Heavy‐duty construction tasks implemented by hydraulic manipulators are highly challenging due to unstructured hazardous environments. Considering many tasks have quasirepetitive features (such as cyclic material handling or excavation), a multitarget adaptive virtual fixture (MAVF) method by teleoperation‐based learning from demonstration is proposed to improve task efficiency and safety, by generating an online variable assistance force on the master. First, the demonstration trajectory of picking scattered materials is learned to extract its distribution and the nominal trajectory is generated. Then, the MAVF is established and adjusted online by a defined nonlinear variable stiffness and position deviation from the nominal trajectory. An energy tank is introduced to regulate the stiffness so that passivity and stability can be ensured. Taking the operation mode without virtual fixture (VF) assistance and with traditional weighted adaptation VF as comparisons, two groups of tests with and without time delay were carried out to validate the proposed method.

To examine whether cognitive frailty serves as a predictor of hospitalisation in older adults. PubMed, Web of Science, Embase, Scopus and Cochrane Library databases were systematically searched from inception to February 6, 2024. The reviewers independently selected studies, extracted data and evaluated the quality of studies. Stata 15.1 Software was used to perform the meta‐analysis. A total of 13 articles were included in this study, including 34 230 participants. The results suggested that cognitive frailty was associated with hospitalisation in older adults (odds ratio (OR) = 1.79, 95% CI: 1.33–2.42, P < 0.001). The risk of hospitalisation for patients with cognitive frailty was 1.76 times higher than that for patients without cognitive frailty (relative risk = 1.76, 95% CI: 1.48–2.08, P < 0.001). According to different models of cognitive frailty, the results of subgroup analysis showed that the frail + cognitive impairment group had the highest risk of hospitalisation (OR = 2.22, 95% CI: 1.51–3.26, P < 0.001). Subgroup analysis based on study design showed that the incidence of hospitalisation was lowest in the cohort study group (OR = 1.51, 95% CI: 1.14–2.00, P = 0.004). This study suggested that cognitive frailty was an important predictor of hospitalisation in older adults. Future studies are needed to investigate the impact of cognitive frailty on hospitalisation in older adults, as this may help reduce hospitalisation rates and improve patients' quality of life.

Glutathione (GSH) is one of the most abundant bioethanol antioxidants in living cells. Here, a fluorescent probe based on MnO2 nanosheets and sulfur quantum dots (SQDs) was fabricated. Because of the synergistic effect of IFE and FRET, the fluorescence from SQDs was quenched by MnO2 nanosheets. In the presence of GSH, the fluorescence of SQDs could be recovered because of the reduction of MnO2 nanosheets by GSH. The method can detect GSH in the concentration range of 5 ~ 1000 μM with the detection limit as low as 1.26 μM. This quick, easy, and cost‐effective sensor could be used for the quantification of GSH in serum samples and the imaging of GSH in Escherichia coli O157:H7. [ABSTRACT FROM AUTHOR]

BACKGROUND: Aphid infestation adversely affects the yield and quality of crops. Rapid reproduction and insecticidal resistance have made controlling aphids in the field challenging. Therefore, the present study investigated the insecticidal property of Penicillium oxalicum (QLhf‐1) and its mechanism of action against aphids, Hyalopterus arundimis Fabricius. RESULTS: Bioassay revealed that the control efficacy of the spores against aphids (86.30% and 89.05% on the third day and fifth day after infection, respectively) were higher than other components, such as the mycelium. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) showed that QLhf‐1 invaded the aphid cuticle through spores and used the aphid tissues as a nutrient source for growth and reproduction, causing stiffness and atrophy and a final death. Three extracellular enzymes, lipase, protease, and chitinase had a synergistic effect with spores, and they acted together to complete the infection process by degrading the aphid body wall and accelerating the infection process. CONCLUSION: The newly discovered endophytic penicillin strain P. oxalicum 'QLhf‐1' can effectively kill aphids. The results provided strong evidence for the biological control of aphids, and lay a foundation for the development and utilization of QLhf‐1. © 2024 Society of Chemical Industry.

The plating/stripping efficiency of zinc (Zn) is directly related to the efficiency of zinc utilization and cycle stability of the battery, which is affected by factors such as the solvated water‐related hydrogen evolution reaction (HER), Zn corrosion, and dendrite formation. Therefore, creating a weak solvate shell for Zn2+ with reduced solvated water molecules can promote stable deposition and stripping of the zinc anode. In this work, a novel approach using the concentrated charge effect of anions is proposed to remove the solvated water and improve the efficiency of Zn plating/stripping. 3 mol kg−1 (3 m) ZnCl2, Zn(ClO4)2, and Zn(BF4)2 electrolytes are used as the representatives to investigate how anions regulate the solvent shell of zinc ion to achieve high Zn plating/stripping Coulombic efficiency (CE). Computational results show that Cl− has a more concentrated charge compared to ClO4− and BF4−, indicating a stronger interaction with Zn2+. This concentrated charge effect reduces the number of water molecules in Zn2+ solvation structures. Benefiting from weak solvent structure, the average coulomb efficiency, and cycling stability of the Zn─Cu asymmetric cell using ZnCl2 electrolyte is better. Additionally, the Zn‐NaV3O8 full cell of the ZnCl2 electrolyte exhibits good electrochemical performance. [ABSTRACT FROM AUTHOR]

Graphitic carbon nitride (g‐C3N4) assisted photocatalytic production of hydrogen peroxide (H2O2 has already attracted the interest of many researchers due to its environmental sustainability. Nevertheless, the inherent drawbacks of g‐C3N4 limit its progress. Metal‐free modification strategies, including nanostructure design, defect introduction, doping, and heterojunction construction, have been developed to improve the efficiency of g‐C3N4 photocatalytic H2O2 production. Compared to metal modification, metal‐free strategies avoid the use of precious metals and the leaching of heavy metal ions, which have the advantages of good stability and environmental friendliness. However, a comprehensive review of H2O2 production from g‐C3N4 modified by metal‐free strategies is still lacking. This review first recaps the mechanism of photocatalytic H2O2 production by g‐C3N4, including photoexcitation, carrier separation and redox reactions. Then, the perspective advances in metal‐free modified g‐C3N4 photocatalysts are presented, with the special focus on the kernel connection between different strategies and mechanism based on the pivotal stages of H2O2 production. Subsequently, recent applications of g‐C3N4‐based photocatalysts for in situ generated H2O2, mainly including water purification and organic synthesis, are briefly discussed. Finally, the prospects of g‐C3N4‐based photocatalysts are envisioned with the hope that it will have "something to do" in the field of H2O2 production. [ABSTRACT FROM AUTHOR]

Zn metal as a promising anode for aqueous batteries suffers from severe zinc dendrites, anion‐related side reactions, hydrogen evolution reaction (HER) and narrow electrochemical stable window (ESW). Herein, an "anions‐in‐colloid" hydrated deep eutectic electrolyte consisting of Zn(ClO4)2 ⋅ 6H2O, β‐cyclodextrin (β‐CD), and H2O with mass ratio of 7 : 4.5 : 3 (ACDE‐3) is designed to improve the stability of zinc anode. The ACDE‐3 reconfigures the hydrogen‐bond (HB) network and regulates the solvation shell. More importantly, the hydroxyl‐rich β‐cyclodextrins (β‐CDs) in ACDE‐3 self‐assemble into micelles, in which the steric effect between adjacent β‐CDs in micelles restricts the movement of anions. This unique "anions‐in‐colloid" structure enables the eutectic system with a high Zn2+ transference number (tZn2+) of 0.84. Thus, ACDE‐3 inhibits the formation of dendrite, prevents the anion‐involved side reactions, suppresses the HER, and enlarges the ESW to 2.32 V. The Zn//Zn symmetric cell delivers a long lifespan of 900 hours at 0.5 mA cm−2, and the Zn//Cu half cells have a high average columbic efficiency (ACE) of 97.9 % at 0.5 mA cm−2 from cycle 15 to 200 with a uniform and compact zinc deposition. When matched with a poly(1,5‐naphthalenediamine) (poly(1, 5‐NAPD)) cathode, the full battery with a low negative/positive capacity (N/P) ratio of 2 can still cycle steadily for 200 cycles at a current density of 1.0 A g−1. Additionally, this electrolyte has been proven to be operative over a wide temperature range from −40 °C to 40 °C. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study is to investigate the prevalence and risk factor of cognitive frailty in patients undergoing maintenance hemodialysis. Methods: Systematically searched PubMed, EmBase, Web of Science, Cochrane Library, SinoMed, China Knowledge Resource Integrated Database, Wanfang Database, and Weipu Database from inception until January 1, 2024. Two researchers were independently screened and cross‐checked. Stata 15.1 software was used to perform the meta‐analysis. Results: A total of 15 articles were included, including 5398 patients. The results showed that the prevalence of cognitive frailty in patients undergoing maintenance hemodialysis was 24%. Among them, age (odds ratio [OR] = 1.33, 95% CI [1.16, 1.53]), waist circumference (OR = 1.05, 95% CI [1.03, 1.08]), malnutrition (OR = 2.91, 95% CI [1.94, 4.35]), comorbidities (OR = 1.93, 95% CI [1.47, 2.54]), stroke history (OR = 2.94, 95% CI [1.72, 5.03]), and depression (OR = 3.26, 95% CI [1.91, 5.57]) were the main risk factors for cognitive frailty in patients undergoing maintenance hemodialysis. Education level (OR = 0.48, 95% CI [0.31, 0.73]) was protective factors for cognitive frailty in patients undergoing maintenance hemodialysis. Conclusions: Current evidence showed that the prevalence of cognitive frailty in patients undergoing maintenance hemodialysis was high, and there were many risk factors. Therefore, early identification and intervention of cognitive frailty in maintenance hemodialysis patients should be carried out, which may be helpful to reduce the prevalence rate and occurrence of adverse events and improve the prognosis of patients.

2D van der Waals (vdW) magnets provide the ideal platform for studying magnetism at low dimensions, where the magnetic properties can be further tuned by intercalating magnetic species and manipulating their stoichiometry and local atomic configuration. However, achieving stoichiometric intercalated 2D magnets necessitates precise control of growth parameters to avoid local compositional variations, which fosters phase coexistence that significantly impacts magnetic properties. Here a comprehensive scanning transmission electron microscopy (STEM) examination of the structural evolution in chemical vapor deposition (CVD)‐grown self‐intercalated V1+xSe2 nanoplates is shown, exploring their response to annealing temperature variations and the subsequent influence on magnetic properties. By combining ex situ and in situ post‐growth annealing, the rearrangement of intercalants is directly observed at the interlayer and identify a structural phase transition of the nanodomains embedded in the VSe2 matrix from V3Se4 to a V5Se8 structure occurring at ≈250 °C. The interlayer reconstruction is manifested by a positive‐to‐negative cross‐over in the magnetoresistance and an upturn in resistivity at low temperatures. The results provide new ways for tailoring 2D vdW magnets through post‐growth thermal annealing. [ABSTRACT FROM AUTHOR]

Direct air capture (DAC) is a negative emission technology for removing CO2 from the atmosphere to maintain the CO2 level within a reasonable range so as to address greenhouse effects. In this study, the operational optimization of lab‐scale DAC has been investigated using a crossflow air‐liquid contactor loaded with a three dimensionally printed Gyroid packing structure and a potassium sarcosinate solvent. The effects of various parameters, including feed air flow rate, liquid solvent flow rate, contactor geometry, and ambient temperature, are examined. The results demonstrate that the Gyroid packing design achieves comparable CO2 capture performance to conventional packed beds but with a significantly lower pressure drop of up to 77.8%, suggesting its potential as an efficient and cost‐effective solution for gas–liquid contactors in DAC. Additionally, the study explores the climate impact on CO2 capture performance and finds that as the air temperature increases from 35 to 95°F at a fixed relative humidity of 80%, the CO2 capture rate increased from 23.2% to 46.8% with better stability. The research highlights the importance of optimizing contactor design and operational conditions to improve the CO2 capture rate and feasibility of DAC systems as a negative emission technology for addressing greenhouse effects.

Patient‐derived organoids (PDOs) may facilitate treatment selection. This retrospective cohort study evaluated the feasibility and clinical benefit of using PDOs to guide personalized treatment in metastatic breast cancer (MBC). Patients diagnosed with MBC were recruited between January 2019 and August 2022. PDOs were established and the efficacy of customized drug panels was determined by measuring cell mortality after drug exposure. Patients receiving organoid‐guided treatment (OGT) were matched 1:2 by nearest neighbor propensity scores with patients receiving treatment of physician's choice (TPC). The primary outcome was progression‐free survival. Secondary outcomes included objective response rate and disease control rate. Targeted gene sequencing and pathway enrichment analysis were performed. Forty‐six PDOs (46 of 51, 90.2%) were generated from 45 MBC patients. PDO drug screening showed an accuracy of 78.4% (95% CI 64.9%–91.9%) in predicting clinical responses. Thirty‐six OGT patients were matched to 69 TPC patients. OGT was associated with prolonged median progression‐free survival (11.0 months vs. 5.0 months; hazard ratio 0.53 [95% CI 0.33–0.85]; p =.01) and improved disease control (88.9% vs. 63.8%; odd ratio 4.26 [1.44–18.62]) compared with TPC. The objective response rate of both groups was similar. Pathway enrichment analysis in hormone receptor‐positive, human epidermal growth factor receptor 2‐negative patients demonstrated differentially modulated pathways implicated in DNA repair and transcriptional regulation in those with reduced response to capecitabine/gemcitabine, and pathways associated with cell cycle regulation in those with reduced response to palbociclib. Our study shows that PDO‐based functional precision medicine is a feasible and effective strategy for MBC treatment optimization and customization. [ABSTRACT FROM AUTHOR]

The further development of aqueous zinc (Zn)‐ion batteries (AZIBs) is constrained by the high freezing points and the instability on Zn anodes. Current improvement strategies mainly focus on regulating hydrogen bond (HB) donors (H) of solvent water to disrupt HBs, while neglecting the environment of HB‐acceptors (O). Herein, we propose a mechanism of chaotropic cation‐regulated HB‐acceptor via a "super hydrous solvated" structure. Chaotropic Ca2+ can form a solvated structure via competitively binding O atoms in H2O, effectively breaking the HBs among H2O molecules, thereby reducing the glass transition temperature of hybrid 1 mol L−1 (M) ZnCl2+4 M CaCl2 electrolyte (−113.2 °C). Meanwhile, the high hydratability of Ca2+ contributes to the water‐poor solvated structure of Zn2+, suppressing side reactions and uneven Zn deposition. Benefiting from the anti‐freezing electrolyte and high reversible Zn anode, the Zn||Pyrene‐4,5,9,10‐tetraone (PTO) batteries deliver an ultrahigh capacity of 183.9 mAh g−1 at 1.0 A g−1 over 1600‐time stable cycling at −60 °C. This work presents a cheap and efficient aqueous electrolyte to simultaneously improve low‐temperature performances and Zn stability, broadening the design concepts for antifreeze electrolytes.

Summary: Plants typically activate distinct defense pathways against various pathogens. Heightened resistance to one pathogen often coincides with increased susceptibility to another pathogen. However, the underlying molecular basis of this antagonistic response remains unclear.Here, we demonstrate that mutants defective in the transcription factor ETHYLENE‐INSENSITIVE 3‐LIKE 2 (OsEIL2) exhibited enhanced resistance to the biotrophic bacterial pathogen Xanthomonas oryzae pv oryzae and to the hemibiotrophic fungal pathogen Magnaporthe oryzae, but enhanced susceptibility to the necrotrophic fungal pathogen Rhizoctonia solani.Furthermore, necrotroph‐induced OsEIL2 binds to the promoter of OsWRKY67 with high affinity, leading to the upregulation of salicylic acid (SA)/jasmonic acid (JA) pathway genes and increased SA/JA levels, ultimately resulting in enhanced resistance.However, biotroph‐ and hemibiotroph‐induced OsEIL2 targets OsERF083, resulting in the inhibition of SA/JA pathway genes and decreased SA/JA levels, ultimately leading to reduced resistance. Our findings unveil a previously uncharacterized defense mechanism wherein two distinct transcriptional regulatory modules differentially mediate immunity against pathogens with different lifestyles through the transcriptional reprogramming of phytohormone pathway genes.

In this work, surface‐modified Ce‐Zr oxides and ZnO nanoparticles were conveniently prepared by dopamine (Dpa) treatment and then composited with epoxy (EP) by hot pressing. Thermogravimetric analysis (TGA) and UV‐shielding properties of the EP composites with surface modification with Dpa‐CZ and Dpa‐ZnO were measured. The TGA results showed that the modified treated fillers had no loss of heat resistance of the matrix and had an enhancement effect on the initial and maximum decomposition temperatures. In addition, the UV‐shielding properties of EP composites after Dpa‐CZ and Dpa‐ZnO modifications both showed a significant enhancement effect compared to pure EP. The T(UVA) of the 0.5 wt% Dpa‐ZnO modified composite decreased to less than 0.017%, and the T(UVB) decreased to less than 0.0059%. The T(UVA) of the 0.5 wt% Dpa‐CZ modified composite decreased to less than 15.98%, and the T(UVB) decreased to below 1.14%. The composites have both excellent thermal stability and UV‐shielding efficiency. [ABSTRACT FROM AUTHOR]

The Vela pulsar is a young neutron star with spin period of P = 89 ms and a measured low braking index (˜1.4) that is much less than the standard value of 3 predicted by the magnetic dipole radiation (MDR) model; however, its spin period evolution has been a mystery. In this article, we assume that the spin‐down of the Vela pulsar is attributed to both MDR and wind flow (hereafter MDRW), and find that the ratio of wind flow to the magnetic dipole radiation is about 80%, which is higher than that of the Crab pulsar (25%). In other words, the spin‐down torque of the Vela pulsar is dominated by the wind flow. The spin period (P) evolution of the Vela pulsar depends on its real age, where its supernova remnant age is assumed to be an indicator of its true age, estimated from 10 to 20 kyr, and then we obtain their initial spin periods of ˜53.89 and ˜20.90 ms, respectively, which are consistent with the observed initial spin period ranges of young pulsars. Furthermore, we find that the Vela‐like pulsar by MDRW can evolve to the long spin period of a thousand of seconds in less than million years, which can conveniently help the astronomers understand the recently observed ultra‐long period radio pulsars like GPM J1839‐10 (P = 21 min), GLEAM‐X J1627 (P = 18 min), as well as PSR J0901+4046 (P = 76 s).

Circular economy products are one of the solutions that can help solve the current environmental crisis and consequently achieve environmental sustainability. The theory of planned behavior (TPB) is the most important social psychological theory to explain individual purchasing behavior. However, the theory lacks a consideration of emotions, green altruism, and other factors. In order to address the research gap, this study proposes and tests a new theoretical model that incorporates variables such as emotions, green altruism, and the willingness to be environmentally friendly (WEF) into its extended model based on the TPB framework, in order to investigate the determinants that have an effect on Taiwanese consumers' purchase intention toward circular economy products. This study also uses multi‐group analysis (MGA) to analyze the moderating effects of WEF on its new theoretical model. It collected data from 387 Taiwanese consumers and analyzed the data using partial least squares (PLS). The research results showed (1) emotions, attitudes, green altruism, and perceived behavior control have a positive effect on consumer purchase intention toward circular economy products; (2) emotions have a positive effect on attitudes, green altruism, subjective norms, and perceived behavior control; and (3) groups with different levels of WEF have significant differences on consumer purchase intention toward circular economy products, in terms of emotions, attitudes, and green altruism. The results of this study can provide a reference for manufacturers and public policy makers to understand how consumers' emotions and green altruism can affect the decision‐making process to making purchase of circular economy products.

Structure from motion (SfM) using optical images has been an important prerequisite for reconstructing three‐dimensional (3D) landforms. Although various algorithms have been developed in the past, they suffer from many image pairs for feature matching and recursive searching for the most suitable image to add to SfM reconstruction. Thus, carrying out SfM is computationally costly. This research proposes a boosting SfM (B‐SfM) pipeline containing two phases, indexing graph network (IGN) and graph tracking, to accelerate SfM reconstruction. The IGN intends to form image pairs presenting desirable spatial correlation to reduce the time costs spent for feature matching. Building on the IGN, graph tracking integrates ant colony optimisation and greedy sorting algorithms to encode an optimum image sequence to boost SfM reconstruction. Compared to the results derived from other available means, the experimental results show that the proposed approach can accelerate the two phases, feature matching and 3D reconstruction, by up to 14 times faster. The quality of the camera poses recovered is retained or even slightly improved. As a result, the developed B‐SfM can efficiently achieve SfM reconstruction by suppressing the time cost in the fashion of image pair selection for feature matching and image order determination for more efficient SfM reconstruction.

The widely discussed single‐atom catalysts (SACs) are regarded as a kind of attractive material for sulfate radical‐based advanced oxidation processes (SR‐AOPs) owing to their maximum atomic utilization efficiency and outstanding stability. Currently, metal–organic frameworks (MOFs) have appeared as prospective precursors for building SACs due to extensive chelating sites, functional adjustability, and structural tunability. However, there are few critical and systematic reviews about the application of MOF‐derived SACs in SR‐AOPs, especially in‐depth analysis of the mechanisms. Therefore, this review seeks to offer a thorough summary of the development of MOF‐derived SACs in SR‐AOPs. First, the unique advantages of MOFs as derivative precursors for SACs are discussed thoroughly. Afterward, the current synthesis strategies are elaborated categorically to unveil the formation process of single atoms and their coordination environments. Notably, the roles of different reaction sites including the generation of reactive species and mediating electron transfer are further analyzed to explain mechanisms comprehensively. Thereafter, the characterization techniques and theoretical calculations for mechanisms studies are also highlighted. Eventually, critical insights into present challenges and future developments are proposed, which are expected to enhance the catalytic efficiency of MOF‐derived SACs in SR‐AOPs.

Reported test results suggest reinforcement grade can have an important effect on the seismic displacement demands of reinforced concrete (RC) structures. Two one‐story one‐bay RC frames (Specimens C1 and H1) were mounted in parallel on the NCREE‐Taiwan shake table and simultaneously subjected to 16 base motions, each representing a horizontal component of recorded earthquakes. The dynamic tests were followed by quasi‐static large‐amplitude cyclic testing. The specimens had the same nominal dimensions and base shear strengths with longitudinal reinforcement that was Grade 60 (60 ksi [420 MPa]) in C1 and Grade 100 (100 ksi [690 MPa]) in H1. Maximum drifts of H1 were 1.3 to 2.3 times larger than for C1. The lateral stiffness of H1 was consistently lower than C1, with stiffness ratios (H1 to C1) ranging from 0.78 after Run 1 to 0.45 after Run 16. Drift estimates using stiffness values based on gross‐section properties provided a reasonable upper bound for C1 but were unconservative for H1. Drift estimates based on the secant‐to‐yield stiffnesses, which were inversely proportional to reinforcement grade, provided an upper bound for both specimens. Preliminary recommendations are made for accounting for these effects in design. [ABSTRACT FROM AUTHOR]

Background: Weak theory of mind (ToM) ability is a core deficit in children with autism. A growing body of work has found that there is a close relation between complement syntax and ToM in autistic children. However, researchers have not yet investigated whether other linguistic components may explain the difficulties in ToM reasoning in autistic children. Aims: To determine whether verb factuality (i.e., mental and action verbs) is related to ToM ability, as measured by a false belief understanding (FBU) task after controlling the effect of complement syntax for Mandarin‐speaking autistic children. Methods & Procedures: Participants were verbal autistic children, aged 4–7 years. Their IQ performance (verbal, performance and total IQ) and the comprehension of complement syntax were evaluated. A total of 38 children scoring over 9 points in complement syntax test and 90 points in the verbal IQ test were selected to complete verb factuality and FBU task. The χ2 tests and correlation analyses were carried out on two relations: (1) ToM ability and understanding of verb factuality; and (2) ToM ability and comprehension of complement syntax. Outcomes & Results: A total of 11 autistic children completed the action verb factuality task, while 14 completed the mental verb factuality task and 13 completed both tasks. Participants performed well on the verb factuality task, and their ToM performance appeared to be related to their linguistic ability, regardless of the type of verb (i.e., action or mental verb). However, complement syntax scores did not significantly predict the success of the FBU task for the autistic children. Conclusions & Implications: The results of this study link weaker ToM ability with the understanding of verb factuality among autistic children aged 4–7 and provide new evidence for the view that the development of language facilitates improvement of ToM skills. The findings shed new light on how language affects or determines social interactions. WHAT THIS PAPER ADDS: What is already known on the subject: ToM ability is crucial for social interaction. It has been claimed that mental verb factuality (e.g., think, had thought) may play a role in the development of ToM reasoning in typically developing children, but whether there is a link between the mastery of verb factuality and ToM skills in autistic children is still unclear. What this study adds to existing knowledge: Correlational analysis revealed links between verbal ToM measured by unexpected location task and factuality test of mental verbs as well as action verbs. More importantly, this study confirmed the extra role of verb factuality in explaining ToM ability after excluding the influence of the complement syntax. What are the potential or actual clinical implications of this work?: This study suggests that the factuality of verbs could serve as a tool for autistic children to infer the mental states of others. Thus, training on this linguistic structure could be taken into consideration when improving the social skills of autistic children. [ABSTRACT FROM AUTHOR]

The metallo‐β‐lactamases (MβLs) produced by pathogens has issued a challenge to the treatment of bacterial infections worldwide. A number of oxazolethioacetamides were designed and synthesized as potential MβLs inhibitors. Most of the compounds displayed inhibitory activity against MβL L1 with an IC50 value range of 0.19–0.38 μM. The fluorine substituted compounds also inhibited VIM‐2 with IC50 value of 2.1 to 6.8 μM. Molecule Docking showed the style and position of electron withdrawing groups played important role between the oxazolethioacetamides and MβLs. [ABSTRACT FROM AUTHOR]

Previous studies have shown that the addition of carboplatin to neoadjuvant chemotherapy improved the pathologic complete response (pCR) rate in patients suffering from triple‐negative breast cancer (TNBC) and patients who obtained a pCR could achieve prolonged event‐free survival (EFS) and overall survival (OS). However, no studies have assessed the effects of the combination of docetaxel and carboplatin without anthracycline with taxane‐based and anthracycline‐based regimens. The NeoCART study was designed as a multicenter, randomized controlled, open‐label, phase II trial to assess the efficacy and safety of docetaxel combined with carboplatin in untreated stage II‐III TNBC. All eligible patients were randomly assigned, at a 1:1 ratio, to an experimental docetaxel plus carboplatin (DCb) for six cycles group (DCb group) or an epirubicin plus cyclophosphamide for four cycles followed by docetaxel for four cycles group (EC‐D group). PCR (ypT0/is ypN0) was evaluated as the primary outcome. Between 1 September 2016 and 31 December 2019, 93 patients were randomly assigned and 88 patients were evaluated for the primary endpoint (44 patients in each group). In the primary endpoint analysis, 27 patients in the DCb group (61.4%, 95% CI 47.0‐75.8) and 17 patients in the EC‐D group achieved a pCR (38.6%, 95% CI 24.3‐53.0; odds ratio 2.52, 95% CI 2.4‐43.1; Pnoninferiority =.004). Noninferiority was met, and the DCb regimen was confirmed to be superior to the EC‐D regimen (P =.044, superiority margin of 5%). At the end of the 37‐month median follow‐up period, OS and EFS rates were equivalent in both groups. What's new? In triple‐negative breast cancer (TNBC), neoadjuvant chemotherapy based on anthracycline and taxane can improve survival, if pathologic complete response (pCR) is achieved. The addition of carboplatin to this neoadjuvant regimen for TNBC potentially improves pCR rate. The randomized trial reported here shows that, compared to a standard taxane‐ and anthracycline‐based regimen without carboplatin, pCR rate is significantly improved by combining docetaxel and carboplatin and leaving out anthracycline. Survival rates were similar between the different regimens. The findings suggest that docetaxel plus carboplatin is a promising alternative approach, particularly in TNBC patients who have a contraindication to treatment with an anthracycline.

Many lacewing species (Insecta: Neuroptera) are important predators of pests with great potential in biological control. So far, there is no chromosome‐level published genome available for Neuroptera. Here we report a high‐quality chromosome‐level reference genome for a green lacewing species Chrysopa pallens (Neuroptera: Chrysopidae), which is one of the most important insect natural enemies used in pest biocontrol. The genome was sequenced using a combination of PacBio and Hi‐C technologies and assembled into seven chromosomes with a total size of 517.21 Mb, occupying 96.07% of the genome sequence. A total of 12,840 protein‐coding genes were identified and approximately 206.21 Mb of repeated sequences were annotated. Phylogenetic analyses indicated that C. pallens diverged from its common ancestor with Tribolium castaneum (Coleoptera) approximately 300 million years ago. The gene families involved in digestion, detoxification, chemoreception, carbohydrate metabolism, immunity, nerves and development were significantly expanded, revealing the potential genomic basis for the polyphagia of C. pallens and its role as an excellent biocontrol agent. This high‐quality genome of C. pallens will provide an important genomic resource for future population genetics, evolutionary and phylogenetic investigations of Chrysopidae as well as comparative genomic studies of Neuropterida and other insects.

Somatic copy number alterations (CNAs) are a genomic hallmark of cancers. Among them, the chromosome 17p13.1 deletions are recurrent in hepatocellular carcinoma (HCC). Here, utilizing an integrative omics analysis, we screened out a novel tumour suppressor gene within 17p13.1, myosin heavy chain 10 (MYH10). We observed frequent deletions (~38%) and significant down‐regulation of MYH10 in primary HCC tissues. Deletion or decreased expression of MYH10 was a potential indicator of poor outcomes in HCC patients. Knockdown of MYH10 significantly promotes HCC cell migration and invasion in vitro, and overexpression of MYH10 exhibits opposite effects. Further, inhibition of MYH10 markedly potentiates HCC metastasis in vivo. We preliminarily elucidated the mechanism by which loss of MYH10 promotes HCC metastasis by facilitating EGFR pathway activation.

Objective: The overall prognosis of benign convulsions associated with mild gastroenteritis (CwG) is favorable, and the incidence of afebrile seizure recurrence with or without gastroenteritis (ASwGI and ASwoGI, respectively) is low. In this study we investigated the prognostic factors associated with afebrile seizure (AS) relapse after the first CwG episode. Methods: A hospital‐based cohort with an initial CwG episode from January 2012 to October 2019 was followed for at least 19 months. The relapse types were divided into ASwGI and ASwoGI. Logistic regression analysis was performed to identify the independent prognostic factors for the recurrence of AS after the initial CwG episode. Furthermore, the clinical characteristics between ASwGI and ASwoGI were compared. Results: Among the 868 patients enrolled, 67 (7.7%) experienced a second AS and 71% (48/67) showed gastroenteritis‐associated recurrence. Except for five patients with subsequent epilepsy (0.6%), only eight (0.9%) experienced three seizure episodes. The independent predictive factors for the subsequent recurrence of AS were age less than 18 months at onset (odds ratio [OR]: 2.93, 95% confidence interval [CI]: 1.53–5.63), repeated seizures over 24 h (OR: 4.09, 95% CI: 2.19–7.65), and absence of fever (OR: 2.33, 95% CI: 1.26–4.33) during the first CwG episode. The probability of recurrence of AS for those with one, two, and three predictive factors was 3.23%, 13.35%, and 22.85%, respectively. In addition, the age at onset was significantly lower in the ASwoGI group than in the ASwGI group during the first episode (p <.05). Significance: The risk of AS relapse after the initial CwG episode is low, and the majority of patients presented with gastroenteritis. The risk can be predicted by age at onset, repeated seizures over 24 h, and absence of fever during the first CwG episode. [ABSTRACT FROM AUTHOR]

The transcription factor grainy head (Grh) functions in the protection of the epithelium against the external environment by generating strongly adhesive layers, and this function is conserved in vertebrates and invertebrates. In Drosophila, the top model for holometabolous insects, Grh is necessary during embryonic development, epidermal differentiation, central nervous system specification and epithelial repair. However, the function of this gene in hemimetabolous insect epithelia remains unknown. To examine the function of Grh signaling in regulating epithelium development in Hemimetabola, we focused on the Blattella germanica epidermal layer using a gene knockdown strategy. The spatiotemporal expression pattern of BgGrh was detected, and knockdown of BgGrh and BgCad96ca, which provide positive feedback to BgGrh, caused severe defects in new epithelium development and impeded the molting process required to discard the old integument. Knockdown of the expression of BgGrh and BgCad96ca caused increased expression of chitin synthase gene (BgCHS1) and chitinase gene (BgCht5), the upregulations of which should be mediated by the higher level of hormone receptor 3 (BgHr3) gene. In conclusion, epithelium development is regulated by Grh signaling, which might represent a potential target for the control of urban pest cockroaches. [ABSTRACT FROM AUTHOR]

Cobalt sulfides have been popularly used in energy storage because of their high theoretical capacity and abundant redox reactions. However, poor reaction kinetics, rapid capacity decay, and severe polarization owing to volume changes during electrochemical reaction are still huge challenges for cobalt sulfides in practical applications. Herein, cobalt sulfide yolk–shell spheres were synthesized by phosphorus doping (P‐CoS) to stabilize the structure of cobalt sulfides and improve their electronic/ion conductivity. Kinetic tests and density functional theory calculations confirm that the introduction of phosphorus into cobalt sulfides greatly reduces the diffusion barrier of Li+ in the intrinsic structure, thereby improving the reaction kinetics of electrode materials during the Li+ insertion/extraction process. In consequence, the P‐CoS electrode delivers a high lithium storage capacity (781 mAh g−1 after 100 cycles at 0.2 A g−1), excellent rate capability (489 mAh g−1 at 10 A g−1), and outstanding cycling stability (no significant capacity decay over 4000 cycles at 5 A g−1). Especially for sodium‐ion battery application, the P‐CoS electrode expresses a striking capacity of approximately 260 mAh g−1 at 2 A g−1 after 900 cycles. [ABSTRACT FROM AUTHOR]

To overcome the low energy density bottleneck of graphene‐based supercapacitors and to organically endow them with high‐power density, ultralong‐life cycles, etc., one rational strategy that couple graphene sheets with multielectron, redox‐reversible, and structurally‐stable organic compounds. Herein, a graphene‐indanthrone (IDT) donor–π–acceptor heterojunction is conceptualized for efficient and smooth 6H+/6e− transfers from pseudocapacitive IDT molecules to electrochemical double‐layer capacitive graphene scaffolds. To construct this, water‐processable graphene oxide (GO) is employed as a graphene precursor, and to in situ exfoliate IDT industrial dyestuff, followed by a hydrothermally‐induced reduction toward GO and self‐assembly between reduced GO (rGO) donors (D) and IDT acceptors (A), affording rGO‐π‐IDT D–A heterojunctions. Electrochemical tests indicate that rGO‐π‐IDT heterojunctions deliver a gravimetric capacitance of 535.5 F g−1 and an amplified volumetric capacitance of 685.4 F cm−3. The assembled flexible all‐solid‐state supercapacitor yields impressive volumetric energy densities of 31.3 and 25.1 W h L−1, respectively, at low and high power densities of 767 and 38 554 W L−1, while exhibiting an exceptional rate capability, cycling stability, and enduring mechanically‐challenging bending and distortions. The concept and methodology may open up opportunities for other two‐dimensional materials and other energy‐related devices. [ABSTRACT FROM AUTHOR]

Currently, development of suitable cathode materials for zinc‐ion batteries (ZIBs) is plagued by the sluggish kinetics of Zn2+ with multivalent charge in the host structure. Herein, it is demonstrated that interlayer Mn2+‐doped layered vanadium oxide (Mn0.15V2O5·nH2O) composites with narrowed direct bandgap manifest greatly boosted electrochemical performance as zinc‐ion battery cathodes. Specifically, the Mn0.15V2O5·nH2O electrode shows a high specific capacity of 367 mAh g−1 at a current density of 0.1 A g−1 as well as excellent retentive capacities of 153 and 122 mAh g−1 after 8000 cycles at high current densities up to 10 and 20 A g−1, respectively. Even at a low temperature of −20 °C, a reversible specific capacity of 100 mAh g−1 can be achieved at a current density of 2.0 A g−1 after 3000 cycles. The superior electrochemical performance originates from the synergistic effects between the layered nanostructures and interlayer doping of Mn2+ ions and water molecules, which can enhance the electrons/ions transport kinetics and structural stability during cycling. With the aid of various ex situ characterization technologies and density functional theory calculations, the zinc‐ion storage mechanism can be revealed, which provides fundamental guidelines for developing high‐performance cathodes for ZIBs.

Ancestry informative markers play an important role in medical genetics and forensic analyses. Several ancestry informative SNP panels have been developed and validated that can differentiate global populations into continental or major regional groups. These global panels have served as good first‐tier genetic markers; however, their performance in discriminating populations within regions appears unsatisfactory. To boost ancestry inference for regional populations, second‐tier panels with more refined discrimination power among subpopulations within each of the regions need to be developed. In East Asia, Han Chinese, Japanese, and Korean show highly similar externally visible characteristics and are genetically closely related. Reliable ancestry informative genetic markers appear invaluable in discriminating these populations. In the present study, we compiled a genome‐wide SNP dataset composing of 317,439 clean SNPs for a total of 1101 unrelated individuals from Han Chinese (817), Koreans (184), and Japanese (100). From this starting dataset, we developed a set of four nested ancestry informative SNP panels including 36, 59, 98, and 142 SNPs, respectively. The results of cross‐validation tests indicate that these panels can discriminate the Chinese Han, Japanese, and Korean populations with overall average accuracies ranging from 90% to 99%. In the further performance assessments, these panels also manifested high sensitivity and specificity. In combination with the first‐tier global panels, these second‐tier panels would contribute to medical genetics and forensic research in East Asia. [ABSTRACT FROM AUTHOR]

The utilization of noble‐metal catalysts for the hydrogen evolution reaction (HER) provides an efficient strategy for hydrogen acquisition. However, exploring catalysts with suitable hydrogen binding strength for the HER process is always of great importance, but extremely challenging. In this work, sulfur and phosphor as electron‐withdrawing elements were incorporated into carbon nanotube (CNT)‐supported Ru catalysts, which were prepared through a facile solution reduction reaction and post thermo treatment. Owing to the suitable electronegativity provided by P and synergistic effects of the carbon nanotubes, the RuP2/CNT achieved a high catalytic performance as a HER electrocatalyst. This may result from the modulation effect of the electronic properties and the depressed adsorption free energy of RuP2. Electrochemical tests present that the RuP2/CNT composite exhibit a small overpotential of 58 mV at 10 mA cm−2 in acidic electrolyte. In a neutral or alkaline environment, the overpotential is 82 and 40 mV, respectively. The RuP2/CNT electrode also possesses stable durability for long‐time cycling, suggesting its remarkable property as promising all‐pH HER catalyst. [ABSTRACT FROM AUTHOR]

Heat stress can inhibit follicular development in dairy cows, and thus can affect their reproductive performance. Follicular granulosa cells can synthesize estrogen, that affects the development and differentiation of follicles by apoptosis. Heme oxygenase 1 (HO‐1/heat shock protein 32) plays an antiapoptotic and cytoprotective role in various cells during stress‐induced apoptosis, but little is known about its definitive function in bovine (ovarian) granulosa cells (bGCs). In our study, the roles and mechanism of HO‐1 on the heat stress‐induced apoptosis of bGCs were studied. Our results show that the expression of HO‐1 was significantly increased under heat stress. Moreover, HO‐1 silencing increased apoptosis, whereas its overexpression dampened apoptosis by regulating the expression of Bax/Bcl‐2 and the levels of cleaved caspase‐3. In addition, HO‐1 can also play a cytoprotective role by affecting estrogen levels and decomposing heme to produce biologically active metabolite carbon monoxide (CO). Meanwhile, CO significantly increased the level of HO‐1, decreased Bax/Bcl‐2 levels, and inhibited the activation of extracellular signal‐regulated kinase 1/2 (ERK1/2) signaling pathway. The apoptosis of ovarian GCs can affect the secretion of estrogen and lead to disorder of the ovarian microenvironment, thus affecting the normal function of the ovary. Our results indicate that HO‐1 acts as a cytoprotective enzyme and plays a protective role in heat‐induced apoptosis of bGCs. In conclusion, HO‐1 and its metabolite CO inhibit the apoptosis of bGCs induced by heat stress through the ERK1/2 pathway. The results of this study provide a valuable clue for improving the fertility of heat stressed cows in summer. Heme oxygenase (HO‐1) and its metabolite CO inhibit the apoptosis of bovine granulosa cells (bGCs) induced by heat stress through the extracellular signal‐regulated kinase 1/2 (ERK1/2) pathway. The results of this study provide a target for improving the fertility of heat stressed dairy cows in summer. [ABSTRACT FROM AUTHOR]

The article reports that alcoholic liver disease (ALD), induced by long-term heavy alcohol consumption, encompasses a progressive clinical-histological spectrum of liver injuries from simple fatty liver to alcoholic hepatitis, hepatic fibrosis and cirrhosis. It notes that hepatitis virus infection exerts a synergistic effect on alcohol-induced liver injury. It adds that ALD could both accelerate the development and progression of liver diseases.

Exosome‐encapsulated microRNAs (miRNAs) have been identified as potential biomarkers in autoimmune diseases. However, little is known about the role of exosome‐delivered miRNAs in rheumatoid arthritis (RA). In this study, we investigated the profile of specific exosomal miRNAs by microarray analysis of serum exosomes from three patients with RA and three healthy controls. Quantitative real‐time PCR (qRT‐PCR) was performed to validate the aberrantly expressed exosomal miRNAs. A total of 20 exosome‐encapsulated miRNAs were identified to be differently expressed in the serum of patients with RA compared with controls. Interestingly, we found that exosome‐encapsulated miR‐6089 was significantly decreased after validation by qRT‐PCR in serum exosomes from 76 patients with RA and 20 controls. Besides, miR‐6089 could inhibit lipopolysaccharide (LPS)‐induced cell proliferation and activation of macrophage‐like THP‐1 cells. TLR4 was a direct target for miR‐6089. MiR‐6089 regulated the generation of IL‐6, IL‐29, and TNF‐α by targetedly controlling TLR4 signaling. In conclusion, exosome‐encapsulated miR‐6089 regulates LPS/TLR4‐mediated inflammatory response, which may serve as a novel, promising biomarker in RA. TLR4 is a direct target for miR‐6089. MiR‐6089 regulates the generation of IL‐6, IL‐29, and TNF‐α by targetedly controlling the TLR4 signaling. [ABSTRACT FROM AUTHOR]

We performed a systematic review of genome‐wide gene expression datasets to identify key genes and functional modules involved in the pathogenesis of systemic lupus erythematosus (SLE) at a systems level. Genome‐wide gene expression datasets involving SLE patients were searched in Gene Expression Omnibus and ArrayExpress databases. Robust rank aggregation (RRA) analysis was used to integrate those public datasets and identify key genes associated with SLE. The weighted gene coexpression network analysis (WGCNA) was adapted to identify functional modules involved in SLE pathogenesis, and the gene ontology enrichment analysis was utilized to explore their functions. The aberrant expressions of several randomly selected key genes were further validated in SLE patients through quantitative real‐time polymerase chain reaction. Fifteen genome‐wide gene expression datasets were finally included, which involved a total of 1,778 SLE patients and 408 healthy controls. A large number of significantly upregulated or downregulated genes were identified through RRA analysis, and some of those genes were novel SLE gene signatures and their molecular roles in etiology of SLE remained vague. WGCNA further successfully identified six main functional modules involved in the pathogenesis of SLE. The most important functional module involved in SLE included 182 genes and mainly enriched in biological processes, including defense response to virus, interferon signaling pathway, and cytokine‐mediated signaling pathway. This study identifies a number of key genes and functional coexpression modules involved in SLE, which provides deepening insights into the molecular mechanism of SLE at a systems level and also provides some promising therapeutic targets.

Abstract: A graphene oxide (GO) film is functionalized with metal (Au) and metal‐oxide (MoOx) nanoparticles (NPs) as a hole‐extraction layer for high‐performance inverted planar‐heterojunction perovskite solar cells (PSCs). These NPs can increase the work function of GO, which is confirmed with X‐ray photoelectron spectra, Kelvin probe force microscopy, and ultraviolet photoelectron spectra measurements. The down‐shifts of work functions lead to a decreased level of potential energy and hence increased Voc of the PSC devices. Although the GO‐AuNP film shows rapid hole extraction and increased Voc, a Jsc improvement is not observed because of localization of the extracted holes inside the AuNP that leads to rapid charge recombination, which is confirmed with transient photoelectric measurements. The power conversion efficiency (PCE) of the GO‐AuNP device attains 14.6%, which is comparable with that of the GO‐based device (14.4%). In contrast, the rapid hole extraction from perovskite to the GO‐MoOx layer does not cause trapping of holes and delocalization of holes in the GO film accelerates rapid charge transfer to the indium tin oxide substrate; charge recombination in the perovskite/GO‐MoOx interface is hence significantly retarded. The GO‐MoOx device consequently shows significantly enhanced Voc and Jsc, for which its device performance attains PCE of 16.7% with great reproducibility and enduring stability.

In this study, the authors propose a high‐throughput systolic Dickson basis multiplier over GF(2m). Use of the Dickson basis seems promising when no Gaussian normal basis exists for the field, and it can easily carry out both squaring and multiplication operations. Many squaring operations and multiplications are needed when computing the digital signatures of elliptic curve digital signature algorithm. The proposed systolic Dickson basis multiplier can concurrently compute a great number of multiplications with a high‐throughput rate, thereby substantially increasing the speed of computation for digital signatures.

SIRT7 is a member of the sirtuin family of proteins that are known to be associated with tumor development. However, the functional roles and molecular mechanisms underlying the function of SIRT7 in breast cancer cell survival and tumor development remain unclear. Recent studies demonstrated that SIRT7 is upregulated in breast cancer cells and tissues. In the present study, we systematically explored the roles of SIRT7 in the growth of breast cancer cells and tumors both in vitro and in vivo. Our results showed that SIRT7 plays a major role in facilitating cell survival by promoting cell proliferation and inhibiting apoptosis. SIRT7 depletion significantly inhibited cell invasion and wound healing by blocking cell cycle progression and inducing cell apoptosis. Meanwhile, SIRT7 depletion can increase the sensitivity of breast cancer cells to doxorubicin (DOX). Xenograft model studies showed that stable silencing of SIRT7 inhibited tumor growth and enhanced tumor sensitivity to DOX. Further research revealed that p38MAPK is involved in SIRT7‐mediated regulation of breast cancer cell proliferation and tumor growth. Taken together, our results showed that SIRT7 plays a critical role in breast cancer cell survival, migration, and tumor growth, and increased the efficiency of DOX treatment both in vitro and in vivo. Therefore, SIRT7 is a promising therapeutic target in breast cancer treatment. [ABSTRACT FROM AUTHOR]

The 3d-3d random bimetallic compound [Co2.28Mn0.72(N3)6(mpc-3)2(CH3OH)2] (1) (mpc-3 = N-methylpyridinium-3-carboxylate) was synthesized by partly substituting the CoII ions in the homometallic compound by MnII. Complex 1 was structurally and magnetically characterized. It consists of one-dimensional chains with the neighboring metal ions being linked alternatively by [(μ-EO-N3)2(μ-COO)] (EO = end-on) triple bridges and double EO azide bridges. Hydrogen-bonding interactions and π-π interactions are involved in the formation of a three-dimensional supramolecular network. Magnetic measurements revealed that complex 1 exhibits slow relaxation, which is similar to the homometallic CoII parent compound whereas the TB is lower than that of the CoII analog.

In recent years, subquadratric‐and‐quadratric Toeplitz matrix–vector product (TMVP) computations are widely used for the implementation of binary field multiplication in elliptic curve cryptography. Pure subquadratric TMVP structure involves significantly less space complexity and long computational delay, while quadratric TMVP structure involves larger space complexity and less computation delay. To optimise the tradeoff between time and space complexities, this study presents a novel hybrid multiplier for Gaussian normal basis (GNB) in GF(2m) which combines subquadratic and quadratic structures. From the theoretical analysis, it is shown that the proposed hybrid multiplier can save ∼18% space complexity and 12% time complexity than the existing GNB multiplier with pure TMVP decomposition.
