The high uncertainty around the COVID‐19 pandemic elicited an unprecedented level of panic buying during the early months. Using the framework of stress and coping, the current study conceptualized and tested a theoretical model that predicts individuals' panic buying in two countries. A survey of US (n = 311) and Korean consumers (n = 347) revealed that negative emotions (loneliness and anxiety) contributed to panic buying, yet two important coping resources, resilience and social support, were effective in protecting consumers from engaging in a maladaptive coping strategy. The hypothesis that collectivism (vs. individualism) would make consumers rely on social (vs. personal) coping resources was partially supported. The results highlight the unique circumstance of the global pandemic in which social support works as both a resource for healthy coping and a source to increase negative emotions, and call for future investigation of the complex role of social support in the context of stress and coping theory.

Summary: In recent years, many initial coin offerings (ICOs) scams have been reported, attracting attention to this relatively new and unregulated ICO market, which lacks disclosure requirements and therefore suffers from intensifying problems of information asymmetry inherent in crowdfunding. As a prospectus‐type document, an ICO white paper serves as a major means of voluntary disclosure practices adopted by ventures seeking external financing. Given the importance of an ICO white paper and the difficulty of assessing its quality, we propose to benchmark it against white paper content for security token offerings (STOs)—a more regulated ICO subset. Using the similarity of ICO white papers with STO white papers to proxy for disclosure quality, we document that the ICO campaigns that have white papers more similar to STO white papers are more likely to raise funding successfully. Our findings provide implications for policymakers, ICO fundraisers, and investors on the importance of white paper quality. [ABSTRACT FROM AUTHOR]

Miniaturized paper‐based electrochemical sensors were fabricated using kraft paper and CO2 laser, dispensing the need for chemical reagents and controlled atmospheric conditions. This study initially evaluated the paper type and laser processing parameters, enhancing the electrodes′ robustness, electrochemical response, and electrical resistance. The sensors were also treated by applying −1 V for 60 s in 1.0 mol L−1 KCl, which is a simple and rapid procedure. The electrochemical treatment increased the electroactive area and roughness, confirmed by scanning electron microscopy. These aspects helped modulate the sensors′ electrochemical response for nitrite determination, improving selectivity and sensitivity for this compound. The sensors also showed repeatability and batch‐to‐batch reproducibility, with 2.2 and 10 % RSD, respectively. Therefore, this work brings a protocol to fabricating competitive electrochemical sensors through a sustainable strategy, opening possibilities for designing new analytical systems.

With the emergence of disposable electronics, compatible safe, flexible, and recyclable power sources have become a critical challenge. Here, an ultra‐thin paper‐based iontronic power source is enabled by highly efficient translational Li+ transport within 2D nanofluidic channels of graphene oxide under a salinity gradient and the fine‐tuned interfacial redox reactions. The paper‐based source can generate volumetric power and energy densities of 438.02 mW cm−3 and 30.02 mWh cm−3, respectively. Its areal power density is 1095.05 mW cm−2, surpassing most flexible batteries. It maintains a working state when bent or even cut and can be simply recycled by incineration. By filling 2D nanofluidic inks in different pens, the power source can be drawn on paper when needed, which not only overcomes the inherent defect of self‐discharge for most batteries but also enables writing directly on any insulating substrates. Furthermore, all‐in‐one disposable electronics comprised of an energy management system (paper‐based triboelectric nanogenerator and iontronic power source) and wireless sensing system (temperature sensor with NFC circuits) are integrated onto one piece of paper by duplex printing, demonstrating the huge potential of such integratable iontronic power sources for soft, wireless, and conformable disposable electronics.

The last few years have witnessed the change in the modalities of smuggling of synthetic cannabinoid receptor agonists (SCRAs) by impregnating them in mail envelopes and fast parcels. Considering the aforementioned scenario, it is important to develop a portable technique to identifying SCRAs through packages. The purpose of this research was to detect SCRAs impregnated into substrates of paper using attenuated total reflectance Fourier transform infrared (ATR‐FTIR) spectroscopy. Three SCRAs that included 5F‐PB‐22, AB‐FUBINACA and AKB‐48 were purchased from Sigma Aldrich. The three SCRAs and four cutting agents were impregnated into paper of variable thickness at four concentrations (10, 15, 20, and 25 mg/mL). Spectra were collected over the wavenumber range of 650–4000 cm−1 using ATR‐FTIR spectroscopy and were exported to Matlab 2020b where data analysis was applied. The FTIR spectral data was able to show the three SCRAs could be detected on paper using ATR‐FTIR spectroscopy and quantitatively modeled using the partial least squares regression algorithm. Principal component analysis showed separate clustering for the compounds that crystallized (5F‐PB‐22, AB‐FUBINACA and caffeine) onto the papers surface from those impregnated into the bulk of the paper (AKB‐48 and procaine) with the latter situated near blank papers in score plots. In summary, ATR‐FTIR spectroscopy has proven to be a successful non‐destructive technique in detecting and quantifying a selection of SCRAs impregnated into paper. [ABSTRACT FROM AUTHOR]

Rewritable photonic crystal (PC) paper has the potential to significantly reduce the consumption of forest resources in the printing industry, while also being environmentally friendly and efficient. However, traditional PC papers based on solvent or photothermal responses can lead to diffusion, which can hinder printing accuracy. In this study, a novel rewritable PC paper compatible with pin‐printing is presented based on a pressure‐responsive shape‐memory PC paper. High‐resolution printing can be realized by both computer‐programmed 3D‐printed seals and pin‐printing techniques. The information written on this PC rewritable paper can be erased by water, enabling the paper to be rewritten and reused at least 8 times without any change in performance. Furthermore, the information stored on the PC paper is stable and can be stored in ordinary environments for at least 6 months without fading. The PC paper has the capability of multicolor printing with a precision finer than 100 μm and has potential in office papers, smart price tags, and anti‐counterfeiting labels. [ABSTRACT FROM AUTHOR]

Retracted articles by Indian scholars have received significant attention in recent times. However, no comprehensive study has been conducted to analyse the citations of retracted papers authored by Indian researchers. This study aimed to assess the citations to retracted works published between 2001 and 2020 pre‐ and post‐retraction. The study found that there was an increase in retractions over time, with empirical data suggesting that the number of retractions has increased significantly, from 72 papers between 2001 and 2010 to 365 papers between 2011 and 2020. Duplication (n = 128) and plagiarism (n = 119) were the primary reasons for retraction. Notably, 90% of the retracted articles continued to receive citations after retraction. Among the retracted papers, eight received more than 50 post‐retraction citations, 39 received 20 to 50 citations, 347 received one to 19 citations, and 43 were not cited at all post‐retraction. There was an overall 8% decrease in citations after retraction. Retractions were observed across journals of varying impact factor, with a higher number of retractions observed in journals with an impact factor of less than 5 (n = 286; 65%). Furthermore, smaller research teams of two to five authors accounted for 72% of the total retractions. [ABSTRACT FROM AUTHOR]

The COVID‐19 outbreak led to widespread disruption and stress to people's lives. Concern about the escalation of domestic violence (DV) rates and related mental health issues soon emerged following the implementation of strategies aimed at curbing the spread of the virus. This perspective paper presents an overview of the issues, argues for greater recognition of the link between DV against women and serious emotional distress, and the need for greater awareness and knowledge about DV among mental health professionals. While we acknowledge that men also experience DV, their rates are much lower than for women and in this paper our focus is on women. [ABSTRACT FROM AUTHOR]

FEMALES - Abstract
How might the visibility of an author's name and/or institutional affiliation allow bias to enter the evaluation of economics papers? We ask highly qualified journal editors to review abstracts of solo‐authored papers which differ along the dimensions of gender and institution of the author. We exogenously vary whether editors observe the name and/or institution of the author. We identify positive name visibility effects for female economists and positive institution visibility effects for economists at the top institutions. Our results suggest that male economists at top institutions benefit the most from non‐blind evaluations, followed by female economists (regardless of their institution). [ABSTRACT FROM AUTHOR]

Rationale: Rapid on‐site detection of persistent organic pollutants (POP) is highly desirable for environmental protection. Methods: Herein, a rapid on‐site analytical workflow was developed for the investigation of polycyclic aromatic hydrocarbons and perfluorinated compounds using multiwalled carbon nanotube–modified paper spray ionization (PSI) coupled with a miniature ion trap mass spectrometer. Critical parameters regarding PSI and miniature mass spectrometry analysis were optimized. Results: The analytical performance of the developed method was evaluated under optimized conditions, obtaining a short analysis duration of less than 1 min, sufficient linearity with correlation coefficients greater than 0.99, acceptable recovery rates of 93.1%–105.8% with relative standard deviations of between 3.5% and 10.3%, and reasonable sensitivity with limits of detection and quantitation of 2–200 and 5–500 μg/L, respectively. Conclusions: Considering these aspects, it was concluded that the present approach demonstrated a promising solution for rapid on‐site detection of emerging POPs. [ABSTRACT FROM AUTHOR]

SOCIAL processes , *INSECT societies - Abstract
Vigilant animals detect and respond to threats in the environment, often changing posture and movement patterns. Vigilance is modulated not only by predators but also by conspecific threats. In social animals, precisely how conspecific threats alter vigilance behavior over time is relevant to long‐standing hypotheses about social plasticity. We report persistent effects of a simulated conspecific challenge on behavior of wild northern paper wasp foundresses, Polistes fuscatus. During the founding phase of the colony cycle, conspecific wasps can usurp nests from the resident foundress, representing a severe threat. We used automated tracking to monitor the movement and posture of P. fuscatus foundresses in response to simulated intrusions. Wasps displayed increased movement, greater bilateral wing extension, and reduced antennal separation after the threat was removed. These changes were not observed after presentation with a wooden dowel. By rapidly adjusting individual behavior after fending off an intruder, paper wasp foundresses might invest in surveillance of potential threats, even when such threats are no longer immediately present. The prolonged vigilance‐like behavioral state observed here is relevant to plasticity of social recognition processes in paper wasps. [ABSTRACT FROM AUTHOR]

The rise of fentanyl and fentanyl analogs in the drug supply pose serious threats to public health. Much of these compounds enter the United States through shipping routes. Here we provide a method for fentanyl screening and analysis that utilizes pressure‐sensitive adhesive (PSA) lined paper to recover drug residues from parcel‐related surfaces. The paper used is commercially available repositionable notes (also called post‐it or sticky notes). From this paper, mass spectra were obtained by paper spray‐mass spectrometry (PS‐MS), where PSA paper served as both a sampling and analysis substrate. Seven fentanyl‐related compounds were analyzed: fentanyl, 4‐anilino‐N‐phenethylpiperidine (4‐ANPP), N,1‐diphenethyl‐N‐phenylpiperidin‐4‐amine (phenethyl‐4‐ANPP), valerylfentanyl, 4‐fluoroisobutyrylfentanyl (4‐FIBF), carfentanil, and p‐fluorofentanyl. These compounds were recovered by PSA paper and identified by PS‐MS from packaging tape and plastic at 50 ng and from cardboard and shipping labels at 100 ng. The impact of cutting agents on PS‐MS analysis of fentanyl analogs was explored. No trends of analyte suppression were found at high concentrations of the cutting agents caffeine, diphenhydramine, and lidocaine when recovered from surfaces. A cartridge that required no precise cutting of PSA paper prior to sampling or analysis was evaluated for use in PS‐MS for fentanyl screening. Recovery and detection of fentanyl from plastic sheeting was demonstrated with this cut‐free cartridge. The cut‐free cartridge showed somewhat less consistency and lower analyte signal than the standard cartridge, but performance was suitable for potential screening applications. In combining PSA surface sampling with PS‐MS for drug screening, both sampling and detection of fentanyl‐related compounds is simple, rapid, and low‐cost. [ABSTRACT FROM AUTHOR]

Epoxy‐impregnated paper transformer bushings are prone to water absorption due to the presence of water‐attracting moieties in the cellulose chemical structure and epoxy resin, leading to moisture‐induced insulation defects. To understand the mechanism of moisture's impact on epoxy‐impregnated paper, this study developed a testing platform that integrated moisture diffusion, adsorption, and dielectric properties of insulating materials. Insulation specimens made of epoxy resin and epoxy‐impregnated paper were prepared and their water diffusion characteristics were investigated using the Fick diffusion model and the Langmuir model, respectively. The Guggenheim–Anderson–de Boer equation was used to examine the vacuum vapour adsorption characteristics of the materials, providing a theoretical foundation for examining the form of water present within them. The dielectric response of materials with varying moisture levels was then tested to study the effect of water on the dielectric spectrum curve. Using the Extended Derivative Method, the characteristic frequency reflecting the water content of the epoxy‐impregnated paper was extracted. The results demonstrate that 0.01‐Hz characteristic frequency provides superior accuracy for moisture assessment in epoxy resins compared to 50 Hz, and extracting and fitting the relaxation peak characteristic frequency in epoxy‐impregnated paper moisture evaluation yields higher accuracy than using tan δ at the power frequency.

Summary: The cost‐effective strategy of using paper‐based materials as alternatives to plastics can aid in reducing environmental stress. Herein, a novel green low‐carbon paper‐based food‐packaging composite was synthesised: curcumin microcapsule‐polyvinyl alcohol/beeswax/chitosan (CURM‐PVA/BW/CS) composite papers. Scanning electron microscopy and X‐ray diffraction results confirmed that curcumin was successfully encased and adhered to the paper. The water vapour permeability and oxygen transmission rate of the composite papers were 42.28 g (m2·d)−1 and 3.41 cm3 (m2·d·atm)−1, respectively. The antioxidant capacity of paper was 93.53%, and the mechanical properties were effectively improved by adding natural antioxidants to the coating. Finally, cakes were packaged in the biodegradable 1%CURM‐PVA/BW/CS papers exhibited optimal preservation during the storage period, based on the characterisation of the cake peroxide value, acid value and microbiological count. Overall, the CURM‐PVA/BW/CS paper showed great potential for food packaging. [ABSTRACT FROM AUTHOR]

In this work, poly‐epoxy‐acrylate (PEA) resin was prepared by modifying polyacrylate resin with epoxy resin through a simple solution polymerization method. The prepared PEA resin was then neutralized by alkaline treatment to obtain excellent water solubility and used as an ecofriendly binder for automotive oil filter paper. The effect of alkaline neutralization degree on the water solubility of the PEA resin was studied. Also, the influence of epoxy content on the grafting degree of PEA resin was tested. The mechanical strength and oil resistance properties of oil filter paper strengthened by the prepared PEA resin were compared to other commercial binders. The microstructure and pore size of the oil filter paper were observed by scanning electron microscope and tested by capillary flow porometer (PMI), respectively. The results show that the prepared PEA resin can greatly enhance the mechanical and oil resistance properties of the oil filter paper while maintaining its filtration properties. The prepared PEA resin has the potential to be used as an ecofriendly water‐based binder for automotive oil filter paper. [ABSTRACT FROM AUTHOR]

- Abstract
Sense‐making, sensemaking, and sense making are terms used in different disciplines. Similarities of usage seem unclear. (1) to examine the concepts used in different approaches to sense‐making/sensemaking/sense making; (2) to identify, classify and synthesize recent studies relevant to information science, as well as similar group on sensemaking in education research; (3) to reflect on future directions for sense‐making/sensemaking methodology in information science. The objectives were to retrieve, examine, classify and perform meta‐synthesis on sense‐making/sensemaking studies in both information science and education research. The review used systematic review principles, with selection criteria for case studies for examination in both information science and education sets. The final meta‐synthesis used a meta‐ethnographic approach, together with findings of recent overviews on organizational sensemaking, and other information science reviews. Qualitative sense‐making studies in information science often used Dervin's SMM (sense‐making methodology) and studies in organizations and education frequently used Weick's organizational sensemaking. Different mixed methods approaches were identified. Sense‐making is actively used in research and practice in information science and knowledge management. Using a coherent sense‐making methodology helps and dialogic principles are useful in planning, data collection and analysis. Individual and collective sense‐making are important to information science. [ABSTRACT FROM AUTHOR]

The development of low‐cost and efficient electrolyzer components is crucial for practical electrochemical carbon dioxide reduction (ECR). In this study, facile non‐woven cellulose‐based porous transport layers (PTLs) were developed for high current density CO2‐to‐CO conversion. By depositing a cobalt phthalocyanine (CoPc) catalyst‐layer over the PTLs, we fabricated ECR‐functioning gas‐diffusion‐electrodes (GDEs) for both flow‐cell and zero‐gap electrolyzers. Under optimal conditions, the Faradaic efficiency of CO (FECO) reached 92 % at a high current density of 200 mA cm−2. Furthering the architecture of the GDEs, CoPc was incorporated into the initial PTL slurry, forming ECR‐active PTLs without the need for an additional catalyst‐layer. The new GDE‐architecture favored the CoPc‐distribution by enhancing the contact and interactions with the carbon substrate and demonstrated a stable electrolysis process for over 50 h in a zero‐gap cell at 200 mA cm−2 with a FECO of 80 %.

Transplantation surgery continues to evolve and improve through advancements in transplant technique and technology. With the increased availability of ultrasound machines as well as the continued development of Enhanced Recovery after Surgery (ERAS) protocols, regional anesthesia has become an essential component of providing analgesia and minimizing opioid use perioperatively. Many centers currently utilize peripheral and neuraxial blocks during transplantation surgery, but these techniques are far from standardized practices. The utilization of these procedures is often dependent on transplantation centers' historical methods and perioperative cultures. To date, no formal guidelines or recommendations exist which address the use of regional anesthesia in transplantation surgery. In response, the Society for the Advancement of Transplant Anesthesia (SATA) identified experts in both transplantation surgery and regional anesthesia to review available literature concerning these topics. The goal of this task force was to provide an overview of these publications to help guide transplantation anesthesiologists in utilizing regional anesthesia. The literature search encompassed most transplantation surgeries currently performed and the multitude of associated regional anesthetic techniques. Outcomes analyzed included analgesic effectiveness of the blocks, reduction in other analgesic modalities—particularly opioid use, improvement in patient hemodynamics, as well as associated complications. The findings summarized in this systemic review support the use of regional anesthesia for postoperative pain control after transplantation surgeries. Part 1 of the manuscript focused on regional anesthesia performed in thoracic transplantation surgeries, and part 2 in abdominal transplantations. Specifically, regional anesthesia in liver, kidney, pancreas, intestinal, and uterus transplants or applicable surgeries are discussed. [ABSTRACT FROM AUTHOR]

We present a method to fabricate handcrafted thermoelectric devices on standard office paper substrates. The devices are based on thin films of WS2, Te, and BP (P‐type semiconductors) and TiS3 and TiS2 (N‐type semiconductors), deposited by simply rubbing powder of these materials against paper. The thermoelectric properties of these semiconducting films revealed maximum Seebeck coefficients of (+1.32 ± 0.27) mV K−1 and (−0.82 ± 0.15) mV K−1 for WS2 and TiS3, respectively. Additionally, Peltier elements were fabricated by interconnecting the P‐ and N‐type films with graphite electrodes. A thermopower value up to 6.11 mV K−1 was obtained when the Peltier element were constructed with three junctions. The findings of this work show proof‐of‐concept devices to illustrate the potential application of semiconducting van der Waals materials in future thermoelectric power generation as well as temperature sensing for low‐cost disposable electronic devices.

HYPEREOSINOPHILIC syndrome , *EOSINOPHILS , *BIOLOGICAL specimens , *TASK forces , *PATHOLOGICAL physiology , *HOMEOSTASIS - Abstract
Over the past years, eosinophils have become a focus of scientific interest, especially in the context of their recently uncovered functions (e.g. antiviral, anti‐inflammatory, regulatory). These versatile cells display both beneficial and detrimental activities under various physiological and pathological conditions. Eosinophils are involved in the pathogenesis of many diseases which can be classified into primary (clonal) and secondary (reactive) disorders and idiopathic (hyper)eosinophilic syndromes. Depending on the biological specimen, the eosinophil count in different body compartments may serve as a biomarker reflecting the underlying pathophysiology and/or activity of distinct diseases and as a therapy‐driving (predictive) and monitoring tool. Personalized selection of an appropriate therapeutic strategy directly or indirectly targeting the increased number and/or activity of eosinophils should be based on the understanding of eosinophil homeostasis including their interactions with other immune and non‐immune cells within different body compartments. Hence, restoring as well as maintaining homeostasis within an individual's eosinophil pool is a goal of both specific and non‐specific eosinophil‐targeting therapies. Despite the overall favourable safety profile of the currently available anti‐eosinophil biologics, the effect of eosinophil depletion should be monitored from the perspective of possible unwanted consequences.

To relief the water shortage crisis in China, the Chinese government has initiated a series of clean production (CP) measures to reduce the freshwater consumption and wastewater discharge from paper industry. In this study, a new CP technology was introduced in the paper industry to reuse tissue paper mill effluent water as intake water of corrugated paper mill. The feasibility and impact of the new CP technology was investigated in three different scales, laboratory experiments, pilot‐scale testing, and long‐term implementation. Results show that the water quality of treated tissue paper mill effluent water is competitive with that of freshwater and some water quality indexes are even better, indicating that treated tissue paper mill effluent water is a suitable alternative to replace the freshwater as intake water for the corrugated paper mill. By reusing tissue paper mill effluent water as intake water of corrugated paper mill, most physical properties of different corrugated paper layers are improved or similar as those by using freshwater as intake water in all different scale experiments. Moreover, the new CP technology significantly reduced the freshwater consumption for the corrugated paper mill, eliminated the wastewater discharged from the tissue paper mill, and at the same time, lowered the operation cost for both paper mills in terms of freshwater consumption and wastewater treatment cost. Total 216,000 RMB will be saved every year with an assumption that tissue paper mill provides annual daily average 2000 cubic meter of effluent water to corrugated paper mill every day. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 934–941, 2018 [ABSTRACT FROM AUTHOR]

PAPER mills ,WESTERN immunoblotting - Abstract
In 2018, the community first observed scientific papers in the biomedical literature that seemed to display systematically fabricated data, pointing to the existence of paper mills: unofficial, potentially illegal organizations selling fake scientific manuscripts. In the present article, we share relevant information specifically about the 'raw data' associated with paper mill manuscripts. If a submitted manuscript displays clear indicators of potential paper mill involvement, we found that the raw data at close inspection often raise doubts about their authenticity. In the absence of real data, paper mills may need to fabricate raw data images when responding to requests from journals. Given the necessity to streamline production of fake manuscripts, the alleged raw data might be created using templates. Some potential methods for generating fake Western blot images are discussed. Paying close attention to image data, including graphs, diagrams, plots and tables, ideally at pre‐publication stage, can clearly help prevent publication of incorrect and fabricated information.

Electrode architectures significantly influence the electrochemical performance, flexibility, and applications of lithium‐ion batteries (LiBs). However, the conventional bar coating for fabricating electrodes limits the addition of customized architecture or patterns. In this study, as a novel approach, patterns are integrated into electrodes through large‐scale roll‐to‐roll (R2R) flexographic printing. Additionally, flexible, recyclable, and biodegradable paper are innovatively used as a printing substrate during printing LiBs manufacturing, which exhibited superior printability. Moreover, the paper is modified with a thin‐layer Al2O3 to function as the separator in the printed LiB. The Al2O3‐coated paper enables an admirable wettability for printing, excellent mechanical properties for high‐speed R2R manufacturing, and outstanding thermal stability for the safe and stable operation of LiBs. The assembled paper cells exhibit nearly 100% discharge capacity retention after 1000 cycles at 3 C and outstanding rate performance. This work inspires future large‐scale microbatteries manufacturing integrated with high‐resolution architecture designs. [ABSTRACT FROM AUTHOR]

At the shelf, highly bleached (soft and white) toilet papers samples of different brands and one grayish toilet paper sample of another brand have been selected for spectroscopy and X‐ray diffraction analysis, in order to figure out if they can present allergic components in their chemical composition. Traces of Ca, associated with the presence of CaC2O4H2O was found in one of the highly bleached toilet paper samples and in the grayish one. However, no traces of fungi were found in the scanning electronic microscopy images. A trial correlation between the chemical composition and mechanical properties of the tested toilet paper samples, surprisingly shows that the grayish toilet paper sample presents the highest softness.

Conventional Al‐air batteries are not suitable as portable power devices due to their complicated water management and bulky system. To resolve this issue, the fiber paper‐ and cotton cloth‐based Al‐air batteries were proposed, which exploited the capillary force from the paper (FP) and cotton cloth (CC) to deliver the solutions and eliminated the external pump. The physical features of the FP and CC were gained including the surface morphologies, surface elementary analysis, liquid absorption and flow rates. CC owned larger liquid absorption and faster flow rate due to its hierarchically woven‐spun fiber structure, compared to the randomly oriented fibers of the FP, although the surface of the CC demonstrated lower O/C ratio than that of the FP. So, the performance of the CC‐based Al‐air battery was largely higher than that of the FP‐based battery. The performance of the CC‐based Al‐air battery was optimal at 1.0 M NaOH electrolyte and the anode‐to‐cathode surface area ratio of 1 : 4, with the peak power density of 14.95±0.28 mW cm−2, and the maximum current density of 36.61±0.54 mA cm−2. To apply the CC‐based Al‐air battery, the two‐battery pack connected in series was assembled to drive a timer and light 9 LEDs. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Early and accurate diagnosis of Alzheimer's disease (AD) is critical to improve illness management and outcomes, making neuropsychological measures an essential tool for clinicians. Research has demonstrated that proactive semantic interference (PSI) and failure to recover from PSI (frPSI) are sensitive to cognitive changes in early mild cognitive impairment (MCI) and preclinical AD determined by Aβ load using PET (Loewenstein et al., 2018; Matias‐Guiu et al., 2017; Curiel et al., 2019). These novel constructs are assessed by the LASSI‐L (Crocco et al., 2018; Crocco et al., 2020). The aim of the current study was to compare a new computerized version of this measure, the LASSI‐BC, to the standard paper‐and‐pencil version of the test. Method: 110 cognitively unimpaired (CU) older adults and 79 older adults diagnosed with amnestic MCI (aMCI) were administered the paper‐and‐pencil form of the LASSI‐L, whereas 62 CU and 52 aMCI participants were administered the LASSI‐BC. Their performance was compared to assess the validity of the LASSI‐BC to discriminate between different diagnostic groups. Result: To assess the validity of the computerized version, both the aMCI and CU groups were compared using χ2 test for categorical variables and ANOVA for continuous variables, with adjustment for covariates such as degree of initial learning, sex, education, and language of evaluation. The performance of CU and aMCI groups using either form was relatively commensurate. Notably, sensitivity and specificity of measures of PSI and frPSI on both versions were calculated to assess diagnostic validity, yielding the following Results Sensitivity of 86.5%, Specificity of 88.1%, and Overall Classification of 87.4% for the LASSI‐BC relative to a Sensitivity of 65.0%, Specificity of 83.6%, and Overall Classification of 75.8% obtained for the paper‐and‐pencil LASSI‐L. Conclusion: The LASSI‐BC displayed exceptionally high diagnostic validity which was comparable to the well‐established LASSI‐L. Notably, the advantages of the LASSI‐BC include a more standardized administration, suitability for remote assessment, and an automated scoring mechanism that can be verified by a built‐in audio recording of responses. These findings support the LASSI‐BC, a novel computerized assessment, as an exceptional tool for the early identification of individuals at risk of progressing to dementia. [ABSTRACT FROM AUTHOR]

The release of toilet paper (TP) and food waste (FW) in domestic sewage is a common practice in developed countries. Nevertheless, this practice has started to be used in developing countries where anaerobic digestion is applied. Therefore, this work aimed at evaluating the influence of the presence of TP and FW on the anaerobic digestion process in UASB reactors. During the experiment, two UASB reactors (8L) were fed with synthetic domestic sewage with the addition of toilet paper (TPR) and food waste (FWR) residues, respectively. In the first stage of the experiment (S‐I), the reactors operated with an organic load of 0.97 kg COD.m–3.d–1 (TPR) and 0.96 kgCOD.m–3.d–1 (FWR) and, in the second stage (S‐II), the quantities were increased to 1.58 kgCOD.m–3.d–1 (TPR) and 1.35 kgCOD.m–3.d–1 (FWR). In the experimental period of 110 days, the parameters total and filtered COD, series of solids, pH, alkalinity, and VFA were monitored. The mean removal of total COD was of 79±1% (S‐I) and 75±1% (S‐II) for TPR, and of 81±2% (S‐I) and 76±1% (S‐II) for FWR. Regarding VSS, the mean removal was of 94 ± 2% (S‐I) and 97 ± 1% (S‐II) for TPR, and of 95 ± 3% (S‐I) and 96 ± 1% (S‐II) for FWR. The VFA/TA ratio increased from S‐I (0.03 for TPR and FWR) to S‐II (0.17 to TPR and 0.10 to FWR), responding to the organic load increases, but still in the range of process stability. The added toilet paper or food waste were efficiently removed in both stages, reaching removals higher than 75%. In general, both reactors presented a good performance for the anaerobic process even under changes in organic load and influent composition. This experiment showed the feasibility of the combined treatment of TP or FW with domestic sewage in UASB reactors. [ABSTRACT FROM AUTHOR]

The present study describes the phytoremediation performance of water lettuce (Pistia stratiotes L.) for physicochemical pollutants elimination from paper mill effluent (PME). For this, pot (glass aquarium) experiments were conducted using 0% (BWW: borewell water), 25%, 50%, 75%, and 100% treatments of PME under natural day/light regime. Results of the experiments showed that the highest removal of pH (10.75%), electrical conductivity (EC: 63.82%), total dissolved solids (TDS: 71.20%) biological oxygen demand (BOD: 85.03%), chemical oxygen demand (COD: 80.46%), total Kjeldahl's nitrogen (TKN: 93.03%), phosphorus (P: 85.56%), sodium (Na: 91.89%), potassium (K: 84.04%), calcium (Ca: 84.75%), and magnesium (Mg: 83.62%), most probable number (MPN: 77.63%), and standard plate count (SPC: 74.43%) was noted in 75% treatment of PME after treatment by P. stratiotes. PCA showed the best vector length for TKN, Na, and Ca. The maximum plant growth parameters including, total fresh biomass (81.30 ± 0.28 g), chlorophyll content (3.67 ± 0.05 mg g−1 f.wt), and relative growth rate (0.0051 gg−1 d−1) was also measured in 75% PME treatment after phytoremediation experiments. The findings of this study make useful insight into the biological management of PME through plant‐based pollutant eradication while leftover biomass may be used as a feedstock for low‐cost bioenergy production. Practitioner points: Biological treatment of paper mill effluent using water lettuce is presented.Best reduction of physicochemical and microbiological pollutants was attained in 75% treatment.Maximum production of chlorophyll, plant biomass, and highest growth rate was also observed in 75% treatment.

Regulation of fluorescence and self‐assembly of a salicylaldehyde azine‐containing amphiphile by a water‐soluble pillar[5]arene via host–guest recognition in water was realized. The fluorescence and the self‐assembled aggregates of the bola‐type amphiphile G can be tailored by adding different amounts of water‐soluble pillar[5]arene (WP5). In addition, the emission property and self‐assembly behavior of G and WP5 are responsive to pH conditions. Furthermore, the fluorescence emission property of G and the regulation by WP5 or pH conditions was applied as information encryption material, rewritable paper, and erasable ink. We believe that this fluorescence regulation strategy is promising for the construction of advanced fluorescent organic materials. [ABSTRACT FROM AUTHOR]

Introduction: In allergic asthma patients, one of the more common phenotypes might benefit from allergen immunotherapy (AIT) as add‐on intervention to pharmacological treatment. AIT is a treatment with disease‐modifying modalities, the evidence for efficacy is based on controlled clinical trials following standardized endpoint measures. However, so far there is a lack of a consensus for asthma endpoints in AIT trials. The aim of a task force (TF) of the European Academy of Allergy and Clinical Immunology (EAACI) is evaluating several outcome measures for AIT in allergic asthma. Methods: The following domains of outcome measures in asthmatic patients have been evaluated for this position paper (PP): (i) exacerbation rate, (ii) lung function, (iii) ICS withdrawal, (iv) symptoms and rescue medication use, (v) questionnaires (PROMS), (vi) bronchial/nasal provocation, (vii) allergen exposure chambers (AEC) and (viii) biomarkers. Results: Exacerbation rate can be used as a reliable objective primary outcome; however, there is limited evidence due to different definitions of exacerbation. The time after ICS withdrawal to first exacerbation is considered a primary outcome measure. Besides, the advantages and disadvantages and clinical implications of further domains of asthma endpoints in AIT trials are elaborated in this PP. Conclusion: This EAACI‐PP aims to highlight important aspects of current asthma measures by critically evaluating their applicability for controlled trials of AIT. [ABSTRACT FROM AUTHOR]

BEST practices - Abstract
To achieve scientific progress in terms of building a cumulative body of knowledge, careful attention to benchmarking is of the utmost importance, requiring that proposals of new methods are extensively and carefully compared with their best predecessors, and existing methods subjected to neutral comparison studies. Answers to benchmarking questions should be evidence‐based, with the relevant evidence being collected through well‐thought‐out procedures, in reproducible and replicable ways. In the present paper, we review good research practices in benchmarking from the perspective of the area of cluster analysis. Discussion is given to the theoretical, conceptual underpinnings of benchmarking based on simulated and empirical data in this context. Subsequently, the practicalities of how to address benchmarking questions in clustering are dealt with, and foundational recommendations are made based on existing literature.

Plain language summary: Over one‐quarter of women in the UK have a caesarean birth (CB). More than one in 20 of these births occurs near the end of labour, when the cervix is fully dilated (second stage). In these circumstances, and when labour has been prolonged, the baby's head can become lodged deep in the maternal pelvis making it challenging to deliver the baby. During the caesarean birth, difficulty in delivery of the baby's head may result – this emergency is known as impacted fetal head (IFH). These are technically challenging births that pose significant risks to both the woman and baby. Complications for the woman include tears in the womb, serious bleeding and longer hospital stay. Babies are at increased risk of injury including damage to the head and face, lack of oxygen to the brain, nerve damage, and in rare cases, the baby may die from these complications. Maternity staff are increasingly encountering IFH at CB, and reports of associated injuries have risen dramatically in recent years. The latest UK studies suggest that IFH may complicate as many as one in 10 unplanned CBs (1.5% of all births) and that two in 100 babies affected by IFH die or are seriously injured. Moreover, there has been a sharp increase in reports of babies having brain injuries when their birth was complicated by IFH. When an IFH occurs, the maternity team can use different approaches to help deliver the baby's head at CB. These include: an assistant (another obstetrician or midwife) pushing the head up from the vagina; delivering the baby feet first; using a specially designed inflatable balloon device to elevate the baby's head and/or giving the mother a medicine to relax the womb. However, there is currently no consensus for how best to manage these births. This has resulted in a lack of confidence among maternity staff, variable practice and potentially avoidable harm in some circumstances. This paper reviews the current evidence regarding the prediction, prevention and management of IFH at CB, integrating findings from a systematic review commissioned from the National Guideline Alliance.

The main insulation structure of the valve‐side winding of converter transformer bears the effect of AC and DC superimposed voltage during operation. The electric field intensity in the pressboard is much higher than that in the pressboard in the AC transformer. This condition increases the probability of failure of insulation structure. Therefore, the design and optimization of the main insulation structure of the valve‐side winding are keys to ensure the stable operation of converter transformer. This study establishes a model of the main insulation structure of the valve‐side winding of the ±1100 kV converter transformer. The influence of the insulating oil–paper configuration on the electric field distribution of the main insulation structure of the valve‐side winding is analysed, and then, an optimization idea is proposed. The oil–paper configuration includes two aspects: oil–paper insulation structural design and combination selection, that is, the influence of typical oil–paper structural design parameters and the aging state of different oil–paper combinations on the electric field distribution. Finally, the optimization idea of the oil–paper configuration for valve‐side winding of converter transformer is obtained, and the established model is optimized. [ABSTRACT FROM AUTHOR]

The employment of ultra‐thin lithium metal anode with high loading cathode is the key to realizing high‐energy‐density rechargeable lithium batteries. Ultra‐thin lithium foils are routinely loaded on a copper substrate in batteries, however, the close contact of these two metals causes galvanic corrosion in the presence of electrolyte, which results in irreversible consumption of lithium and decomposition of electrolyte. Herein, a lightweight and highly conductive flexible graphite paper (GP) is applied to replace Cu foil as the current collector for lithium metal anode. It is demonstrated that the application of GP prevents galvanic corrosion and maintains intimate and steady contact between Li foil and GP current collector during cycling, thereby improving the electrochemical performance of the battery. A 1.08 Ah pouch cell assembled with Li@GP anode and LiNi0.8Co0.1Mn0.1O2 cathode exhibits a long lifetime of 240 cycles with a capacity retention of 91.6% under limited Li, high cathode loading and lean electrolyte conditions.

- Abstract
Rapid and sensitive detection of tetracycline (TC) in the aquatic environment is important for the environmental ecosystem and human health. Herein, we presented on the first attempt to construct a fast‐responding gating system by using horseradish peroxidase (HRP)‐loaded functional RNA superstructures (HRP@3D RNA). Proteins were directly loaded into 3D RNA by the rolling circle transcription (RCT) reaction. We found that the specificity of aptamer‐ligand interaction could serve as a triggered manner to release the loaded HRP from 3D RNA. The above general scheme showed a few minutes of rapid release kinetics. According to the controlled‐release mechanism, we designed a disposable origami paper‐based analytical device (doPAD) coupled with HRP@3D RNA for colorimetric detection of TC. This doPAD can realize target recognition and signal readout by taking advantage of the unique spatial control advantages of 3D origami, thus generating a signal of color change that is positively related to the concentration of TC. This doPAD achieved the quantitative analysis of TC with a limit of detection of 10 nM within 41 min. We envision that the platform will be widely used in the field of environmental monitoring and biosensing. [ABSTRACT FROM AUTHOR]

The efficiency of classical Fenton (CF) and modified Fenton (MF) as well as photo‐Fenton processes in real wastewater treatment of pulp and paper (P&P) mill was investigated in this study. The chemical oxygen demand (COD) was chosen as the reference measurement for evaluating the treatment's efficiency. After determining the optimum parameters for each process, the effect of adding ultrasound (US) on improving treatment efficiency was examined. In addition, kinetic study and phytotoxicity analysis were conducted under optimum conditions for all processes. With pH 4, reaction time 50 min, 1.2 g/L Fe2+ and 8 g/L H2O2 dosages, the best removal efficiency (RE) of COD was determined to be 82.18% in CF process, and this rate rose to 90.1% when US was added. The best RE in MF process was 84.16% with the application of UV‐C, pH 4, reaction time 50 min, 1 g/L Fe0 and 8 g/L H2O2 doses, although it increased to 93.4% when US was applied. The greatest results in the seed germination test were achieved in US processes with 100% of germination percentage (GP) for spinach and tomato and 90% for cress. In the economic evaluation, when conducting the treatment without US, the estimated relative cost decreased in a 15 and 16%, for CF/UV‐C and CF processes respectively, whereas the CF process was 64% cheaper than the MF process in all applications. The US contributed to enhanced water treatment efficiency by having a significant synergistic impact on Fenton applications. Hence, the combination of photo‐Fenton and ultrasound to treat effluent from P&P mills proved to be an effective and promising technique. [ABSTRACT FROM AUTHOR]

The insulation paper is a crucial factor for evaluating the insulation status of transformers. The traditional evaluation methods for insulation paper are dissolved gas component content analysis (CO and CO2) and furfural (2‐FAL) content analysis in oil. The detection principle of the former leads to its low accuracy, while the field application effect of the latter is not ideal due to the easy oxidation of furfural and low content. Methanol, result of its good stability and high production compared with other marker products (CO, CO2, 2‐FAL) has been investigated as a novel marker for aging evaluation of transformer insulating paper in recent years. The results of the investigation indicated that there is a good correlation between the content of methanol in oil and the degree of polymerization under laboratory conditions, which reflected the insulation aging state of the transformer insulating paper more accurately. This paper summarizes the current research status of methanol formation mechanism, detection methods and aging evaluation in insulating oil, and points out the key problems to be solved and development prospects, hoping to provide relevant reference for aging evaluation of oil immersed power transformer.

Flexible sensors have versatile applications in a home environment to create better ambient intelligence, which still have high fabrication costs and disposable value. As a proof‐of‐concept example to resolve these problems, the graphite‐based sensors on a disposable paper cup by laser patterning to measure the water level and temperature are proposed. The optimal process parameters of graphitic film, sensing mechanisms, and the sensor performance are investigated in the experiments. Moreover, the paper cup with graphitic sensors is simulated by the finite element method to analyze the experimental results. This fast and low‐cost manufacturing method may open up avenues for the development of disposable flexible electronics in smart home necessities. [ABSTRACT FROM AUTHOR]

The human absorption, distribution, metabolism, and excretion (hADME) study is the cornerstone of the clinical pharmacology package for small molecule drugs, providing comprehensive information on the rates and routes of disposition and elimination of drug‐related material in humans through the use of 14C‐labeled drug. Significant changes have already been made in the design of the hADME study for many companies, but opportunity exists to continue to re‐think both the design and timing of the hADME study in light of the potential offered by newer technologies, that enable flexibility in particular to reducing the magnitude of the radioactive dose used. This paper provides considerations on the variety of current strategies that exist across a number of pharmaceutical companies and on some of the ongoing debates around a potential move to the so called "human first/human only" approach, already adopted by at least one company. The paper also provides a framework for continuing the discussion in the application of further shifts in the paradigm. [ABSTRACT FROM AUTHOR]

The incineration of high‐moisture solid residues generated at the recycling paper mills represents an energetically unfavourable method of resource utilization. Alternatively, hydrothermal pre‐treatment is considered. In this study, low‐value paper sludges from three different recycling streams were hydrothermally carbonized at 205, 225, and 245°C for 3 h. The raw feedstocks and derived hydrochars were analyzed for energy properties, chemical characteristics, surface morphology, functional groups, and combustion performance employing energy densification and mass yield quantification, scanning electron microscopy, elemental analyzer, Fourier‐transform infrared spectroscopy, and thermogravimetry. The increase in reaction temperature was reported to cause a decrease in mass yield and an increase in energy densification and calorific values corresponding to 5.98%–49.35% and 10.10%–58.51% for raw fibre rejects and final sludge‐derived hydrochar, respectively. Hydrothermal carbonization (HTC) had a non‐significant influence on the energy densification of primary clarifier sludge‐derived hydrochar. Higher reaction temperatures favoured the rate of dehydration and decarboxylation, leading to hydrochars with lower H/C and O/C ratios, thereby enhancing the overall fuel properties. The low‐nitrogen and low‐sulphur fuels obtained validated the effectiveness of HTC treatment to produce high‐quality cleaner solid fuel. The burnout temperature was mostly reduced with an increase in HTC temperature. At HTC‐205 and 225°C, the ignition temperature and the combustion performance increased as a result of the HTC reaction mechanisms. HTC effectively recovered hydrochar with increased carbon content, improved energy densification, and good combustion adequacy. Hydrochar derived from recycling mills may play a role in the energy sector as a substitute for coal or in co‐combustion at coal‐fired power plants. [ABSTRACT FROM AUTHOR]

A simple approach was developed to fabricate high‐performance MXene/cellulose (MC)‐based electromagnetic interference (EMI) shielding papers. The oriented MXene sheets located on one side of cellulose filter paper construct a continuous conductive layer, endowing the MC paper with high electrical conductivity (240.1 S/m) and excellent EMI shielding effectiveness (29.3 dB for 0.192‐mm thickness) at an MXene content of 0.72 vol%. Moreover, the EMI shielding effectiveness of four stacked MC papers reached 40.5 dB. This result means that 99.9911% of the microwave radiation is attenuated, and 0.0089% is transmitted, through the four‐piece MXene/cellulose filter papers. Therefore, MC paper has promising properties for excellent EMI shielding materials in current electronic devices. [ABSTRACT FROM AUTHOR]

Successful practical implementation of bioelectrochemical systems (BES) requires developing affordable electrode structures that promote efficient electrical communication with microbes. Recent efforts have centered on immobilizing bacteria with organic semiconducting polymers on electrodes via electrochemical methods. This approach creates a fixed biocomposite that takes advantage of the increased electrode's electroactive surface area (EASA). Here, it is demonstrated that a biocomposite comprising the water‐soluble conjugated polyelectrolyte CPE‐K and electrogenic Shewanella oneidensis MR‐1 can self‐assemble with carbon paper electrodes, thereby increasing its biocurrent extraction by ≈6‐fold over control biofilms. A ≈1.5‐fold increment in biocurrent extraction is obtained for the biocomposite on carbon paper relative to the biocurrent extracted from gold‐coated counterparts. Electrochemical characterization revealed that the biocomposite stabilized with the carbon paper more quickly than atop flat gold electrodes. Cross‐sectional images show that the biocomposite infiltrates inhomogeneously into the porous carbon structure. Despite an incomplete penetration, the biocomposite can take advantage of the large EASA of the electrode via long‐range electron transport. These results show that previous success on gold electrode platforms can be improved when using more commercially viable and easily manipulated electrode materials. [ABSTRACT FROM AUTHOR]

Paper‐based microfluidic devices are used in point of care diagnostic, sensor technology or lab‐on‐a‐chip devices. Although a number of studies has been reported, only relatively few paper‐based diagnostic tools are available on the market. A remaining challenge is the mechanistic understanding and precise design of capillary flow in paper. Here, silica coatings are applied to control paper wettability, fiber swelling, and thus fluid transport in all three dimensions of a paper sheet via a simple dip‐coating and post‐treatment process. By adjusting the three‐dimensional silica coating distribution, a three‐dimensional asymmetric wettability gradient within the paper sheet is obtained which controls the fluid distribution and imbibition. The correlation between silica coating amount and silica distribution with the resulting fluid behavior is systematically elaborated by analyzing the interaction between fiber and fluid as well as the fiber swelling by applying confocal microscopy. Three different silica‐amount dependent fluid distribution states are demonstrated. These new insights into the mechanism of fluid imbibition using simple silica coatings enable the specific design of different imbibition mechanisms and thus the adjustment of the microfluidic properties in paper‐based microfluidic devices with control over all three spatial dimensions of a paper sheet in one fabrication step.

Pulp and paper companies are characterized by high‐energy consumption and high‐emission in production, placing a heavy burden on the environment. Exploring ways to improve their environmental performance is urgently needed. External coercive pressure from environmental law and internal proactive environmental strategy both enable companies to perform better, but little is known about the difference between them. To close this knowledge gap, our analysis is conducted on a case company in pulp and paper industry to compare the differential impacts of the New Environmental Protection Law of China and the proactive environmental strategy on its environmental performance. In addition, accurately evaluating the environmental performance of pulp and paper companies is essential while research on this topic is scant. Therefore, a novel environmental performance evaluation system for pulp and paper companies (EPESPP) is constructed, including not only internal but also external evaluation indexes based on news reports of various media measured by SNOWNLP sentiment analysis. According to the system, the environmental performance of the case company from 2010 to 2018 is evaluated by the entropy‐weight‐based catastrophe progression method (EWCPM). The results of our case study show that the implementation of a proactive environmental strategy is more conducive to comprehensively improving corporate environmental performance. In other words, the driving effect of the New Environmental Protection Law is not as strong as that of the proactive environmental strategy. [ABSTRACT FROM AUTHOR]

Korean traditional paper known as Hanji is coupled with Ag nanowires (NWs) to be used as multi‐functional paper windows in wooden flame doors of a traditional Korean house (Hanok). The Ag NW is uniformly embedded in a handmade Hanji, consisting of multiple laminated sheets formed through ssangbal filtering up and spray method. The combination demonstrates a low sheet resistance of 28 Ohm square−1 because of a percolating network structure of Ag NWs, which is apt for interconnectors and electrodes. Owing to the flexibility of the Hanji and Ag NWs, outstanding mechanical flexibility, apt for curved or flexible electronic paper windows, is observed. To further examine the potential of the multi‐functional electronic paper window, anti‐bacterial and electromagnetic interference shield properties of the Hanji are also investigated. It is noted that the functional Hanji sterilizes 99.9% of staphylococcus aureus and Klebsiella pneumonia and shows 15 dB (12–18 GHz) shielding efficiency due to the existence of the metallic Ag NWs network. In addition, successful operation of Hanji‐based interconnectors, thin film heaters, and touch panels demonstrates that the Hanji‐based electronic paper window can be used as a device‐integrated paper window in traditional Hanok or oriental traditional houses.
