The special issue contains 17 papers based on extended work presented at the conference, covering topics such as multistatic radar, passive radar, target signatures, and advanced radar processing techniques. The authors hope that this special issue will serve as a valuable resource for further research in the field. [Extracted from the article]

Paper has attracted considerable interest as a promising pressure‐sensing element owing to its foldability/bendability and deformability due to its high porosity. However, paper‐based tactile sensors reported hitherto cannot achieve high sensitivity and a wide sensing range simultaneously. In this study, a resistive tactile sensor using carbon nanotube‐ and silver nanoparticle‐printed mulberry paper as a pressure‐sensing element and electrodes, respectively, is developed. The rough surface and high inner porosity of mulberry paper induce a significant change in the contact area when a multilayer‐stacked structure is used, resulting in increased sensitivity to pressure. Moreover, the enhanced mechanical robustness of mulberry paper originating from the highly bonded network of long and thick fibers affords a wide pressure‐sensing range. The sensor exhibits a high sensitivity exceeding 1 kPa−1 in an applied pressure range of 0.05–900 kPa; this achievement has not been reported among paper‐based tactile sensors. Furthermore, the sensor exhibits a fast response/relaxation time, low detection limit, high resolution, high durability, and high flexibility. The advantages of the sensor afford several applications, including a crosstalk‐free pressure sensor array, a three‐axis pressure sensor, and wearable devices for measuring signals from a user.

In 2014 leading publishers withdrew more than 120 nonsensical publications automatically generated with the SCIgen program. Casual observations suggested that similar problematic papers are still published and sold, without follow‐up retractions. No systematic screening has been performed and the prevalence of such nonsensical publications in the scientific literature is unknown. Our contribution is 2‐fold. First, we designed a detector that combs the scientific literature for grammar‐based computer‐generated papers. Applied to SCIgen, it has a 83.6% precision. Second, we performed a scientometric study of the 243 detected SCIgen‐papers from 19 publishers. We estimate the prevalence of SCIgen‐papers to be 75 per million papers in Information and Computing Sciences. Only 19% of the 243 problematic papers were dealt with: formal retraction (12) or silent removal (34). Publishers still serve and sometimes sell the remaining 197 papers without any caveat. We found evidence of citation manipulation via edited SCIgen bibliographies. This work reveals metric gaming up to the point of absurdity: fraudsters publish nonsensical algorithmically generated papers featuring genuine references. It stresses the need to screen papers for nonsense before peer‐review and chase citation manipulation in published papers. Overall, this is yet another illustration of the harmful effects of the pressure to publish or perish. [ABSTRACT FROM AUTHOR]

Objective: This study assessed the features of the 100 most‐cited papers on oral health‐related quality of life (OHRQoL). Methods: The 100 most‐cited OHRQoL papers were collected from Web of Science, adopting a combined keyword search strategy. Google Scholar and Scopus databases were searched to compare citations. The following data were extracted from papers: title of the paper, number of citations, authorship, country, year of publication, title of the journal, study design, sample size, topic and OHRQoL instruments used. Graphical bibliometric networks were created using VOSviewer software. Results: The number of citations of the top 100 most‐cited OHRQoL papers ranged from 73 to 949. Fifty‐six papers received at least 100 citations and two received more than 400 citations. Most papers were from Canada (23%) and had been published in Community Dentistry and Oral Epidemiology (37%). David Locker was the most‐cited author (25 papers; 3,521 citations). The cross‐sectional study design was the most common (68%). The impact of oral health conditions on OHRQoL (43%) was the most frequent topic, and the Oral Health Impact Profile (OHIP) was the most commonly used OHRQoL instrument (48%). Conclusions: This bibliometric analysis highlighted the characteristics of the 100 most‐cited OHRQoL papers, demonstrating that this field is far from saturated. This list of the most‐cited articles can provide a reference point to guide oral health research, education and services. [ABSTRACT FROM AUTHOR]

Background and Aims: Accurate assessment of patient‐reported oropharyngeal dysphagia (OPD) is essential to guide appropriate management and evaluate response. The Sydney Swallow Questionnaire (SSQ) is a paper‐based 17‐item inventory developed and validated to objectively detect risk of OPD. An easy‐to‐use electronic version with digital output has significant potential in streamlining patient assessment. This study aims to develop and validate an electronic version of the SSQ (eSSQ) against the original paper version. Method: The English‐based paper SSQ was adapted on the online REDcap (Research Electronic Data Capture) platform to be accessible on computer and mobile devices. Patients with OPD and asymptomatic controls completed both electronic and paper versions in randomized order. Patients with stable symptoms then repeated the eSSQ after ≥14 days for test–retest reliability. Paper‐based and eSSQs were also collected from an independent cohort for external validation. Agreement of total scores between both versions and eSSQ test–retest reliability were calculated using two‐way mixed‐effects intra‐class correlation coefficient (ICC). Results: 47 dysphagic patients, 32 controls, and 31 patients from an external validation cohort were recruited. The most common underlying etiology was head and neck cancer. Mean eSSQ total score was 789 in dysphagic patients, and 68 in controls. eSSQ had excellent agreement with paper SSQ in total scores among all participants, with ICC 0.97 (95% CI [0.93, 0.98]) in controls, 0.97 (95% CI [0.94, 0.98]) in dysphagic patients and 0.96 (95% CI [0.92, 0.98]) in validation cohort. Test–retest reliability was also excellent (ICC 0.96, 95% CI [0.90, 0.98]). Conclusion: The newly developed eSSQ shows excellent agreement with the paper version and test–retest reliability. Future applications of its use may allow for more efficient and accessible patient assessment. [ABSTRACT FROM AUTHOR]

A new efficient approach to the synthesis of intensely colored 2‐(2‐oxo‐3H‐pyrrol‐3‐ylidene)malononitrile (OP) was developed. Using the reaction of OP with amines, a series of previously unknown colorless organic salts – dicyano(2‐oxo‐2,5‐dihydro‐1H‐pyrrol‐3‐yl)methanides were synthesized, bearing in the structure two fragments of same or diverse amines of different nature (covalent and ionic). TGA‐DTA study of the synthesized salts showed a thermal reversibility of their formation. The introduction of violet OP into paper followed by treatment with amine vapors revealed prospects of using such a system for naked‐eye detection of volatile amines. It was also shown that OP‐based rewritable paper can be created, to which a data can be applied by local heating and erased by the action of amine or temperature. [ABSTRACT FROM AUTHOR]

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.

Responsive photonic crystals are widely employed to construct rewritable paper, where patterns are written and erased repeatedly via color switching. The working principle mainly lies in the changes on the lattice constant of periodic structures, which, however, restricts the localized color tuning of the recorded patterns and thus limits multicolor information transfer. Herein, a novel strategy is reported to write, erase, and importantly to tune the colors by developing unique light‐driven cholesteric liquid crystals (CLCs) that possess self‐organized helical superstructures with two structural elements of pitch lengths (lattice constant) and helical axes (reconfiguration). Reconfiguration of the helical axes provides two high‐contrast optical states for writing and erasing by pressure and electricity, whereas precise photocontrol of the pitch lengths contributes to localized color tuning. These features primarily capitalize on the light‐driven CLC with diverse photostationary colors, which is induced by a newly designed binary chiral system and confined in the polymer dispersed liquid crystal layer. Distinct multicolor patterns are mechanically written, optically tuned, and electrically erased on the rewritable photonic paper in a programmable manner. Such photonic paper has potential to record, program, and remember optically addressed images in visualized color information and user‐interactive display technologies. [ABSTRACT FROM AUTHOR]

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]

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]

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]

The aim of the present guidance paper is to update the previous ENETS guidelines on well differentiated appendiceal neuroendocrine tumours (NET), providing practical guidance for the diagnosis and management of appendiceal NET (aNET); poorly differentiated neoplasms are dealt with in a separate guidance paper. This paper is structured on a question‐answer format in order to also address controversial issues and areas where uncertainty regarding the management and follow‐up of aNET exists. All recommendations are offered on the basis of the best available evidence, along with the authors' experiences in managing these neoplasms. Each recommendation for treatment will provide a level of evidence and grade of recommendation as per the GRADE system (adapted in Infectious Disease Society of United States Public Health Service grading system).

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]

The value of large‐scale collaborations for solving complex problems is widely recognized, but many barriers hinder meaningful authorship for all on the resulting multi‐author publications. Because many professional benefits arise from authorship, much of the literature on this topic has focused on cheating, conflict and effort documentation. However, approaches specifically recognizing and creatively overcoming barriers to meaningful authorship have received little attention.We have developed an inclusive authorship approach arising from 15 years of experience coordinating the publication of over 100 papers arising from a long‐term, international collaboration of hundreds of scientists.This method of sharing a paper initially as a storyboard with clear expectations, assignments and deadlines fosters communication and creates unambiguous opportunities for all authors to contribute intellectually. By documenting contributions through this multi‐step process, this approach ensures meaningful engagement by each author listed on a publication.The perception that co‐authors on large authorship publications have not meaningfully contributed underlies widespread institutional bias against multi‐authored papers, disincentivizing large collaborations despite their widely recognized value for advancing knowledge. Our approach identifies and overcomes key barriers to meaningful contributions, protecting the value of authorship even on massively multi‐authored publications. [ABSTRACT FROM AUTHOR]

Rational interphase reaction provides a feasible method to overcome the matters of insufficient adsorption of CO2 molecules at the catalytic sites and competitive hydrogen evolution reaction (HER), which can increase the formation rate and selectivity of carbon derivatives in photocatalytic CO2 reduction. Herein, a hydrophobic photocatalyst with TiO2 nanosheet arrays grown on hydrophobic carbon paper (TiO2‐HCP) is fabricated using a combination of magnetron sputtering and hydrothermal method, and its unique structure not only endows it excellent light absorption and effective carrier spatial separation but also avoids the hydrophobic reagent covering reactive sites. When the interphase reaction shifts from solid–liquid diphase to gas‐liquid‐solid tri‐phase, the photocatalytic CO2 reduction over TiO2‐HCP mainly generates CO molecules and effectively suppresses HER due to the HCP suppressing the mass transfer of H2O molecules to active sites. Notably, amounts of H2 byproduct can further react with CO2/CO to produce high value‐added CH4 resultant by modifying the N‐doped TiO2‐HCP with nickel/nickel oxide species. In the tri‐phase interfacial CO2 photoreduction system, the CH4 formation rate of Ni@N‐doped TiO2‐HCP reaches 134.17 µmol m−2 h−1 (about 74.6% selectivity) and total carbon derivatives selectivity is about 93%.

Flexible gas sensors made of polyaniline (PANI)‐reduced graphene oxide (rGO) nanocomposite were prepared using three different substrates, namely filter paper, cotton fabric, and weighing paper, through in‐situ reduction of GO and in‐situ polymerization of aniline. Preliminary analysis showed that the PANI/rGO coated on filter paper possesses a superior electrical conductance than PANI/rGO coated on cotton fabric and weighing paper. Such observation was attributed to the good attachment of the PANI/rGO nanocomposites onto the high‐density mesh‐like structure of the filter paper with rough surfaces. In contrast, PANI/rGO coated onto weighing paper and cotton fabric of different surface structures presented lower‐to‐almost negligible conductance. Accordingly, PANI/rGO filter paper was selected for the subsequent evaluation of gas sensing properties. The gas‐sensing performances of the PANI/rGO filter paper sensors indicated that the 5 wt% PANI/rGO (i.e., 5 wt% rGO) sample exhibited the best response of 306% for 500 ppm carbon dioxide (CO2) gas at room temperature with a recovery rate of 41.5%. On the other hand, the optimum recovery rate of 59.5% was identified at 0.5 wt% PANI/rGO sample which exhibited a response of 155%. Owing to the synergy effect, the PANI/rGO sensor outperformed the sensor made of pure PANI or pure rGO. [ABSTRACT FROM AUTHOR]

Background: Chlorpyrifos is a commonly used organophosphorus pesticide in agriculture. However, its neurotoxicity poses a huge threat to human health. In the present study, a chitosan‐modified filter paper‐based surface enhanced Raman scattering active substrate (Ch/AgNPs/paper) was fabricated and used to detect trace amounts of chlorpyrifos in 120 treated wheat samples. Results: Results showed that the Ch/AgNPs/paper substrate could be used to enhance the chlorpyrifos spectral fingerprint only up to a concentration of 0.000558 mg L−1. Following Raman spectra acquisition, three pre‐processing methods, including Savitzky–Golay (Savitsky–Golay filter with a second order polynomial) smoothing with first derivative and second derivative and normalization, were used to reduce baseline variation and increase resolutions of spectral peak features of the original spectra dataset. Then, prediction models based on partial least squares were established for detecting chlorpyrifos pesticide residue in wheat. The partial least squares model with normalization yielded optimal result, with a correlation coefficient of 0.9764, root mean square error of prediction of 1.22 mg L−1 in the prediction, and relative analysis deviation of 4.12. Five unknown samples were prepared to verify the accuracy of the prediction model. The predicted recoveries were calculated to be between 97.25% and 119.38% with an absolute t value of 0.598. The value of a t‐test shows that the prediction model is accurate and reliable. Conclusion: The present study demonstrates that the proposed method can achieve rapid detection of chlorpyrifos in wheat. © 2022 Society of Chemical Industry. [ABSTRACT FROM AUTHOR]

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]

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]

Background: The HABS‐HD study is an epidemiological study of aging in diverse populations and began transitioning from entirely paper‐based charting to electronic data capture (EDC) in 2018. As the study evolved, the team realized that neuropsychological testing, scoring, and quality review consumed many resources and much staff time. This abstract aims to describe how the HABS‐HD study moved from paper‐based capture of neuropsychological data to EDC with a small data team. Method: The HABS‐HD staff recognized the time commitment for scoring and reviewing scores for the neuropsychological assessment, which created a delay between a participant completing the study and the research diagnosis. Senior research assistants worked with internal developers to create an EDC for the neuropsychological assessment. The data core is small and consists of a director, an assistant director, two developers, two data entry personnel, and a clinician. Specific components were completed on paper to prevent an increase in equipment cost and maintain methodological consistency. These components were reviewed post‐assessment, and a senior research assistant directly entered the scores into the EDC. Result: The EDC neuropsychological assessment was tested before going live. The team adapted data capture from the older method into the EDC. The new system allows the research director to obtain statistics of individual testers and provide more training as needed. It also permits more senior personnel to review the paper components and enter them directly into the EDC, which improves throughput. Conclusion: Smaller data core teams can transition larger projects from paper methods to EDC. The change does not need to be entirely paper or electronic, but investigators should evaluate which methodologies function best for their populations. Finally, communication between the personnel capturing the data, reviewing the quality of the capture, and writing the EDC software is essential. [ABSTRACT FROM AUTHOR]

This Good Practice Paper provides recommendations for the diagnosis, risk stratification and management of the monoclonal gammopathy of undetermined significance (MGUS). It describes the recently recognised entity of the monoclonal gammopathy of clinical significance (MGCS), and recommends how it should be managed. The potential for targeted population screening for MGUS is also discussed., (© 2023 British Society for Haematology and John Wiley & Sons Ltd.)

Cellulases are used in textile, pulp and paper, brewery and wine, sugars, and ethanol industries. Four fungal isolates obtained from organic municipal solid wastes (OMSW) were selected based on their cellulolytic activity on carboxymethyl cellulose (CMC) agar medium. Based on the internal transcribed spacer (ITS) sequence of the ribosomal DNA, the four cellulolytic isolates were identified as Aspergillus fumigatus AKAL1, Aspergillus oryzae AKAL4, Aspergillus flavus AKAL8, and Aspergillus flavus AKAL9. After 9 days of fermentation at 30°C and pH 6.5 under 110 rpm agitation, these isolates produced the maximum amount of cellulase. The cellulase showed optimum activity at temperature 35-40°C and pH 6.0-7.0 and was stable for 1 h at 25-45°C and pH 5.0-7.0. The Mg 2+ and Zn 2+ significantly increased but Hg 2+ , K + , and Ca 2+ severely repressed the cellulase activity. Degradation of filter papers and bio-stoning of denim was successfully done with the crude cellulase. An endo-β-1,4-glucanase was isolated and characterized from Aspergillus isolates. Genome-wide analysis revealed that the genomes of A. oryzae, A. fumigatus, and A. flavus, the pertinent species of the fungal isolates, had 23, 25, and 22 cellulase genes, respectively. Phylogenetic analysis revealed that the cellulases in these fungal species were divided into three major groups, and the isolated endo-β-1,4-glucanase clustered to Group II. Ten different motifs are present in cellulases of the three species. Results herein provide a valuable resource for understanding cellulase genes in Aspergillus species and potential application of cellulase in textile and fermentable sugars production industries., (© 2022 International Union of Biochemistry and Molecular Biology, Inc.)

We tested the use of nasal swabs spotted onto filter paper (Whatman 3M) for the molecular diagnosis of SARS‐CoV‐2 infection. Spots of a positive nasal swab in conservation medium (B.1.177 strain, 21Ct) were still positive (duo E‐gene/IP4) after 10, 20, and 30 days of conservation at room temperature, with Ct values of 28, 27, and 26, respectively. Direct spotting of the swab at bedside (omicron strain) still gave a positive result after 10 days in two RT‐qPCR systems: 33.7 Ct using duo E‐gene/IP4, and 34.8 using a specific Omicron system. Spotting of a dilution range of media spiked with the Delta (strain 2021/FR/0610, lineage B 1.617.2) and Omicron strains (strain UVE/SARS‐CoV‐2/2021/FR/1514) showed a threshold of 0.04 TCID50 after 10 days of conservation. We show, for the first time, that this simple and low‐cost conservation method can be used to store samples for RT‐qPCR against SARS‐CoV‐2 for up to at least 1 month. [ABSTRACT FROM AUTHOR]

There is an urgent need for energy sources with lower environmental impacts to dispose of waste generated by human activities. In this context, a holistic analysis of energy use of waste from agricultural and forestry activities, animal excreta, urban solid waste and sewage, waste from the pulp and paper industry and charcoal in Brazil is presented. Based on a bibliographic review, the current Brazilian panorama is presented in figures giving, a vision of national potential for harnessing bioenergy from this theoretical and technical potential. The QGIS3.24.2 Tisler geoprocessing tool was used to generate potentiality maps from census data of microregions and municipalities available in the IBGE database (2022) and in the Geocentric Reference System for the Americas (SIRGAS 2000). The results of map analysis by micro‐regions of the primary energy from agricultural residues highlight sugar cane, corn and soybeans crops, followed by wastewater and animal excreta. They stood out amont the studied sources of biomass with technical potentials of 53.17, 15.23 and 6.81 GW, respectively. With these results, it is concluded that Brazil could enable around 75 GW installed power, reusing all biomass, potentially 12.5 PJ, without considering the 16 GW already installed from sugarcane and paper black liquor plants.

Ecologists have worked to ascribe function to the variation found in plant populations, communities and ecosystems across environments for at least the past century. The vast body of research in functional ecology has drastically improved understanding of how individuals respond to their environment, communities are assembled and ecosystems function. However, with limited exceptions, few studies have quantified differences in plant function during the earliest stages of the plant life cycle, and fewer have tested how this early variability shapes populations, communities and ecosystems.Drawing from the literature and our collective experience, we describe the current state of knowledge in seedling functional ecology and provide examples of how this subdiscipline can enrich our fundamental understanding of plant function across levels of organisation. To inspire progressive work in this area, we also outline key considerations involved in seedling functional research (who, what, when, where and how to measure seedling traits) and identify remaining challenges and gaps in understanding around methodological approaches.Within this conceptual synthesis, we highlight three critical areas in seedling ecology for future research to target. First, given wide variation in the definition of a 'seedling', we provide a standard definition based on seed reserve dependence while emphasising the need to measure ontogenetic variation more clearly both within and following the seedling stage. Second, studies demonstrate that seedlings can be studied in multiple media (e.g. soil, agar, filter paper) and conditions (e.g. field, greenhouse, laboratory). We recommend that researchers select methods based on explicit goals, yet follow standard guidelines to reduce methodological noise across studies. Third, research is critically needed to assess the implications of different methodologies on trait measurement and compatibility across studies.By highlighting the importance of seedling functional ecology and suggesting pathways to address key challenges, we aim to inspire future research that generates useful and comparable data on seedling functional ecology. This work is critical to explain variation within and among populations, communities and ecosystems and integrate this most vulnerable stage of plant life into ecological frameworks.

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]

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.

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.

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]

Paper has become one of the most promising substrates for building low‐cost and powerful sensing platforms due to its self‐pumping ability and compatibility with multiple patterning methods. Paper‐based sensors have been greatly developed in the field of environmental monitoring. In this review, we introduced the research and application of paper‐based sensors in environmental monitoring, focusing on the deposition and patterning methods of building paper‐based sensors, and summarized the applications of detecting environmental pollutants, including metal ions, anions, explosives, neurotoxins, volatile organic compounds, and small molecules. In addition, the development prospects and challenges of promoting paper‐based sensors are also discussed. The current review will provide references for the construction of portable paper‐based sensors, and has implications for the field of on‐site real‐time detection of the environment.

This study reports the selective hydroxylation of macroscopic carbon surfaces that renders initially hydrophobic carbon fiber paper hydrophilic for more than one year (62 weeks) so far. This long time of sustained hydrophilicity is unprecedented and transforms the utility of macroscopic carbon materials. Quantification of surface oxygenates of a systematic series of 13 chemical treatments reveals that surface hydroxyls are predictors of long‐lasting hydrophilicity. The rapid, mild, acid‐free, transition‐metal‐free treatment does not leave surface residues, inhibits overoxidation of graphitic carbon beyond hydroxyls, and introduces the highest edge density on carbon surfaces, without altering the mesostructure of carbon fiber network architectures and without lowering the flexural strength of carbon fiber paper. Graphitic edges are required for enhanced stability of surface oxygenates that retain a threshold amount of adsorbed water, which is necessary for keeping carbon fiber paper hydrophilic. Application of hydrophilic carbon fiber paper as high‐surface‐area working electrode supports for alkaline water oxidation catalyzed by [NiFe]‐layered double hydroxide nanosheets demonstrates a factor of 60 higher mass activity compared to catalysis on flat basal‐plane highly ordered pyrolytic graphite electrodes.

Among plastic items, single‐use straws are particularly detrimental to marine ecosystems because such straws, including those made of poly(lactic acid) (PLA), are sharp and extremely slowly degradable in the ocean. While paper straws are promising alternatives, they exhibit hydration‐induced swelling even when coated with a non‐degradable plastic coating and promote effervescence (fizzing) in soft drinks owing to their surface heterogeneities. In this study, upgraded paper straw is coated with poly(butylene succinate) cellulose nanocrystal (PBS/CNC) composites. CNC increases adhesion to paper owing to their similar chemical structures, optimizes crystalline PBS spherulites through effective nucleation, and reinforces the matrix through its anisotropic and rigid features. The straws are not only anti‐fizzing when used with soft drinks owing to their homogeneous and seamless surface coatings, but also highly water‐resistant and tough owing to their watertight surfaces. All degradable components effectively decompose under aerobic composting and in the marine environment. This technology contributes to United Nations Sustainable Development Goal 14 (Life Below Water). [ABSTRACT FROM AUTHOR]

Human–machine interaction will be revolutionarily different in the future Internet of Things (IoT) environments. Many displays will be adopted onto electronic devices to enhance human–device communication, even under a very bright sunlight ambience. Thus, power consumption and sunlight visibility are important attributes for this application. Electrophoretic displays (EPDs) have the inherent advantages of ultra‐low power consumption and high sunlight visibility, which are perfectly suitable for IoT applications. The low power consumption resulted from the balance of viscosity, gravity, and other complicated forces involved in the electrophoretic dispersion. This force balance is generally termed "bistability," meaning the particle‐packing can be stable without external power at black and white image states. However, good bistability implies a slow image updating rate, significantly degrades users' experience. In this work, a 3D network structure that undergoes disruption and reorganization with the particles' movement is utilized in the electrophoretic ink dispersion. Dynamic viscosity modulation enables the bistable and fast‐response dual‐working modes. The newly developed design can increase the response speed of EPDs by a factor of 2.38, simultaneously maintaining the bistability. The electronic ink with this reversible network provides a promising solution for the future video‐rate e‐paper displays. [ABSTRACT FROM AUTHOR]
