This paper presents the effect of varying the type of Z‐pin on the delamination bridging performance of unidirectional composite laminates. Carbon and Kevlar Z‐pins were inserted in thick composite laminates using the pre‐hole insertion Z‐pinning process and their bridging performance characterized across the different mode‐mixity range. The bridging response indicated that Kevlar Z‐pin experienced load reduction driven by interfacial friction (Stage III), which was absent in the Carbon Z‐pin. When Mode II dominated the bridging crack, Kevlar Z‐pin showed partial pullout and fiber shear cracking, while the Carbon Z‐pin exhibited clean transverse fracture. Although the bridging load obtained by the Carbon Z‐pin was twice that of Kevlar Z‐pin, the Kevlar Z‐pin provided a higher interlaminar fracture energy. The superior bridging performance of Kevlar Z‐pin is correlated with the enhanced ductility. Moreover, the resin‐rich area was involved in deformation and provided the extra axial load of Z‐pin. Highlights: The comparison of mixed‐mode bridging mechanism between Kevlar Z‐pin and Carbon Z‐pin.Reveal the variation of multi‐directional load and energy consumption with mixed‐mode angle in thick laminates.Detailed scanning electron microscope observation to understand failure characteristics of ductile Z‐pin.Evidence that the extra axial load of Z‐pin provided by resin‐rich area.

Chemical self‐recharging zinc ion batteries (ZIBs), which are capable of auto‐recharging in ambient air, are promising in self‐powered battery systems. Nevertheless, the exclusive reliance on chemical energy from oxygen for ZIBs charging often would bring some obstacles in charging efficiency. Herein, we develop photo‐assisted chemical self‐recharging aqueous ZIBs with a heterojunction of MoS2/SnO2 cathode, which are favorable to enhancing both the charging and discharging efficiency as well as the chemical self‐charging capabilities under illumination. The photo‐assisted process promotes the electron transfer from MoS2/SnO2 to oxygen, accelerating the occurrence of the oxidation reaction during chemical self‐charging. Furthermore, the electrons within the MoS2/SnO2 cathode exhibit a low transfer impedance under illumination, which is beneficial to reducing the migration barrier of Zn2+ within the cathode and thereby facilitating the uniform inserting of Zn2+ into MoS2/SnO2 cathode during discharging. This photo‐assisted chemical self‐recharging mechanism enables ZIBs to attain a maximum self‐charging potential of 0.95 V within 3 hours, a considerable self‐charging capacity of 202.5 mAh g−1 and excellent cycling performance in a self‐charging mode. This work not only provides a route for optimizing chemical self‐charging energy storage, but also broadens the potential application of aqueous ZIBs. [ABSTRACT FROM AUTHOR]

It is well known that the properties of a crystal evolve as it increases in size from a single atomic plane to that of the bulk. Such size‐dependent transitions can stem from many different origins and depend on minute changes to crystal bonding and composition. A model example is that of LaCoO3, which is non‐magnetic in the bulk but can display ferromagnetism at the nanoscale. Here, the evolution of structure‐property relationships is studied in the LaCoO3−δ/SrTiO3 (001) system as the thickness of LaCoO3−δ is increased from a single plane to 10 unit cells. In situ synchrotron X‐ray studies are performed during and post‐deposition to probe changes in the interactions between structure, stoichiometry, and magnetic behavior. Structural quantification indicates that the oxygen octahedral rotation pattern evolves with thickness, due to inherent differences in crystal symmetry between the film and substrate. The change in rotation modifies the required energy barrier for the spin state transition via the Co–O bond length and Co–O–Co bond angle, affecting the appearance of ferromagnetism. Our results highlight the contributions of high spin Co2+ and/or high spin Co3+ to respective weak and robust ferromagnetism and the evolution of properties with size in ultrathin LaCoO3−δ heterostructures.

Aim: To investigate the association between metabolically healthy obesity (MHO) and left ventricular geometric remodelling in Chinese children. Materials and Methods: This cross‐sectional study used data from two population‐based samples in China, including 2871 children aged 6–11 years. Weight status was defined based on body mass index according to the World Health Organization growth chart. Metabolic status was defined based on the 2018 consensus‐based criteria proposed by Damanhoury et al. Obes Rev 2018;19:1476–1491 (blood pressure, lipids and glucose). Left ventricular geometric remodelling was determined as concentric remodelling, eccentric hypertrophy, and concentric hypertrophy. Multinomial logistic regression analysis was used to determine odds ratios (ORs) and 95% confidence intervals (CIs) for the association between categories of weight and metabolic status and left ventricular geometric remodelling. Results: Compared with children with metabolically healthy normal weight, those with MHO had higher odds of left ventricular geometric remodelling, with adjusted ORs (95% CIs) of 2.01 (1.23–3.28) for concentric remodelling, 6.36 (4.03–10.04) for eccentric hypertrophy, and 17.07 (7.97–36.58) for concentric hypertrophy. Corresponding ORs (95% CIs) were 2.35 (1.47–3.75), 10.85 (7.11–16.55), and 18.56 (8.63–39.94), respectively, for children with metabolically unhealthy obesity. In contrast, metabolically unhealthy normal weight was not associated with higher odds of left ventricular geometric remodelling. Findings were consistent in sensitivity analyses that used different definitions of weight and metabolic status and left ventricular geometric remodelling. Conclusions: Children with MHO had higher odds of left ventricular geometric remodelling than their metabolically healthy normal weight counterparts. Our findings suggest MHO may not be a benign condition for cardiac health in children. [ABSTRACT FROM AUTHOR]

FAULT gouge ,SUBDUCTION zones ,FAULT zones ,EARTHQUAKE zones ,EARTHQUAKES ,KAOLINITE - Abstract
Several borehole cores intersecting faults related to coseismic slip display high‐temperature features, including thermal decomposition of fault gouge. We present evidence that these features may be related to fluid drainage of the slip zone during seismic slip. We sheared water‐saturated kaolinite powders under both fluid drained and undrained conditions, expected for seismic slip at shallow crustal depths. Our results show typical dynamic weakening behavior regardless of conditions. Under fluid drained condition, restrengthening accompanied by the thermal decomposition of kaolinite occurs. In addition, thermal decomposition of kaolinite tends to be initiated at high normal stresses (>5 MPa) with short displacement (<5 m). We propose that thermal pressurization acts as a weakening mechanism but ceases because of fluid drainage, triggering kaolinite thermal decomposition. This finding explains seismic‐slip‐related clay anomalies at depth rather than at the surface, as observed in the borehole after the 1999 Mw 7.6 Chi‐Chi earthquake, Taiwan. Plain Language Summary: Seismic faulting at depth can drive thermochemical reactions within the slip zone, given the high slip velocity and large displacement. Several slip‐zone samples from deep drilling projects following catastrophic earthquakes have exhibited high‐temperature geological characteristics, which were not present in fault zone outcrops hosting surface ruptures. We sheared kaolinite (as an analogue of fault zone materials) under both fluid drained and undrained conditions, simulating conditions expected during seismic slip at borehole depths. Our results show that, regardless of the applied conditions, the materials tend to weaken dramatically during shearing. However, when fluids are allowed to drain from the slip zone, there is a subsequent strengthening accompanied by the thermal decomposition of kaolinite. We suggest that thermal pressurization operates as the weakening mechanism but is ceased due to fluid drainage, resulting in the thermal decomposition of kaolinite gouges. In addition, the thermal decomposition of kaolinite tends to be triggered at large normal stresses. Because kaolinite is a common component in both fault zones and subduction zones at shallow depths, our findings have potential implications for reported thermally driven reactions within slip zones as a potential seismic indicator at shallow crustal depths. Key Points: Thermal pressurization operates as the dynamic weakening mechanism during experimental seismic slip regardless of the ambient conditionsThermal pressurization ceases because of fluid drainage and is followed by kaolinite thermal decompositionThermal decomposition of kaolinite tends to be initiated at large normal stresses in the seismic slip range [ABSTRACT FROM AUTHOR]

PHOTONIC crystals ,STRUCTURAL colors ,COLLOIDAL crystals ,OPTICAL materials ,DIELECTRIC materials - Abstract
Photonic crystals are a new class of optical microstructure materials characterized by a dielectric constant that varies periodically with space and features a photonic bandgap. Inspired by natural photonic crystals such as butterfly scales, a series of artificial photonic crystals are developed for use in integrated photonic platforms, biosensing, communication, and other fields. Among them, colloidal photonic crystals (CPCs) have gained widespread attention due to their excellent optical properties and advantages, such as ease of preparation and functionalization. This work reviews the classification and self‐assembly principles of CPCs, details some of the latest biomedical applications of large‐area, high‐quality CPCs prepared using advanced self‐assembly methods, summarizes the existing challenges in CPC construction and application, and anticipates future development directions and optimization strategy. With further advancements, CPCs are expected to play a more critical role in biosensors, drug delivery, cell research, and other fields, bringing significant benefits to biomedical research and clinical practice.

Articular cartilage is a tissue with relatively poor self‐regeneration capacity due to insufficient blood vessels and chondrocytes in the region. Biomaterial‐assisted tissue engineering has shown great potential in cartilage regeneration. However, there are still many worries over the uses of exogenous growth factors, stem cells and scaffolds. To address these concerns, here a dynamic proteinaceous hydrogel with a self‐recruiting ability of cartilage‐inducing factor for in situ cartilage regeneration is reported. The dynamic hydrogel (Pep‐GelSH) is prepared by using thiol‐modified gelatin and thiol‐capped TGF‐β1‐affinity peptide through the Au‐S coordination. The injectability and self‐recovery of Pep‐GelSH hydrogel enabled not only minimally invasive implantation but also the adaptability of the scaffold to irregular defect shapes. Meanwhile, the dynamic hydrogel showed improved adherence to the host tissue and allowed quick infiltration of host cells. More importantly, the hydrogel significantly enhanced local enrichment of endogenous TGF‐β1 and led to the recruitment of stem cells in vivo. After implantation, the hydrogel scaffold triggered the innate repair capacity of cartilage defects by successively promoting stem cells recruitment, infiltration and differentiation, resulting in significantly enhanced chondrogenesis and improved cartilage repair. Therefore, the study in this work may provide a feasible and promising approach for in situ cartilage regeneration. [ABSTRACT FROM AUTHOR]

Energy information is vulnerable to malicious denial of service (DoS) attacks due to the diversity and openness of the smart grid environment. In order to cope with the above challenges, this paper first proposes to adopt Markov hopping model to describe the random packet loss of measurement due to DoS attacks. Then, based on Holt two‐parameter exponential smoothing and untraced Kalman filtering techniques, a one‐step predictive value compensation method for measurement data loss is proposed, and an improved dynamic untraced particle filtering algorithm based on data fusion compensation strategy is designed. Finally, an IEEE‐30 bus system is used to simulate the proposed dynamic state estimation method, which proves that the proposed method can effectively resist DoS attack. [ABSTRACT FROM AUTHOR]

MXene, a highly regarded material, has garnered significant attention within the electromagnetic wave (EMW) absorption field. However, the practical application of MXene is limited in harsh environments. Herein, a magic technique strategy of intercalation growth nucleation engineering is employed to prepare multifunctional MXene‐based EMW absorption materials. By regularly introducing different metal ions between the layers of MXene, an ultrathin absorber can be achieved by annealing after reacting in specific positions. The synthesized MCFC‐69‐8 shows hydrophobicity properties and exhibits a large charge‐transfer resistance of 18112 Ω cm2 with a low corrosion rate and corrosion rate, indicating a good anti‐corrosion property. Through applying a series of mathematical methods, MCFC‐69‐8 shows 25% relaxation polarization loss and 75% conduction loss, and its relaxation time is linked with the specific type of relaxation polarization loss, resulting in an effective absorption bandwidth (EAB) of 4.9 GHz with an ultra‐thin optimal matching thickness of 1.48 mm. Finally, an absorber is built using CST to attain an ultrabroad EAB covering 2–18 GHz. This engineering not only simplifies the intercalation process but also achieves a high‐performance and anti‐corrosion EMW absorber, providing a valuable perception for realizing thinner MXene‐based EMW absorbers in the future.

Sunlight has long served as primary energy source on our planet, shaping the behavior of living organisms. Extensive research has been dedicated to unraveling the evolutionary pathways involved. When the formation of Earth atmosphere, it primarily consisted of small gas molecules, which are considered crucial for the emergence of life. Recent demonstrations have shown that these molecules can also be transformed into semiconductors, with the potential to harness solar energy and catalyze chemical reactions as photocatalysts. Building upon this research, this minireview focuses on the potential revolutionary impact of photocatalysis on Earth. Initially, it examines key reactions, such as the formation of prebiotic molecules and the oxygen evolution reaction via water oxidation. Additionally, various C−N complexes in photocatalysts are explored, showcasing their roles in catalyzing chemical reactions.

Electrocatalytic conversion of CO2 into formate is recognized an economically‐viable route to upgrade CO2, but requires high overpotential to realize the high selectivity owing to high energy barrier for driving the involved proton‐coupled electron transfer (PCET) processes and serious ignorance of the second PCET. Herein, we surmount the challenge through sequential regulation of the potential‐determining step (PDS) over Te‐doped Bi (TeBi) nanotips. Computational studies unravel the incorporation of Te heteroatoms alters the PDS from the first PCET to the second one by substantially lowering the formation barrier for *OCHO intermediate, and the high‐curvature nanotips induce enhanced electric field that can steer the formation of asymmetric *HCOOH. In this scenario, the thermodynamic barrier for *OCHO and *HCOOH can be sequentially decreased, thus enabling a high formate selectivity at low overpotential. Experimentally, distinct TeBi nanostructures are obtained via controlling Te content in the precursor and TeBi nanotips achieve >90 % of Faradaic efficiency for formate production over a comparatively positive potential window (−0.57 V to −1.08 V). The strong Bi−Te covalent bonds also afford a robust stability. In an optimized membrane electrode assembly device, the formate production rate at 3.2 V reaches 10.1 mmol h−1 cm−2, demonstrating great potential for practical application. [ABSTRACT FROM AUTHOR]

BACTERIAL communities , *MICROBIAL diversity , *SOIL microbiology , *PLANT diversity , *FUNGAL communities - Abstract
Studies have shown that the microbiome of saline‐tolerant plants plays a significant role in promoting salt stress in non‐saline‐tolerant plants, but the microorganisms are still unclear. In the present study, the microbial diversity changes in Suaeda salsa (L.) Pall. in the Yellow River Delta region were investigated. In the bacterial community, the dominant bacteria in the rhizosphere soil of the low‐saline soil (YDL), moderate‐saline soil (YDM), and high‐saline soil (YDH) groups were Proteobacteria, Chloroflexi, Bacteroidota, and Actinobacteriota (at the phylum level), while Ascomycota and Basidiomycota were the dominant fungi in the fungal community. At the family level, with the increase of salinity, the relative abundance of Rhodobacteraceae (bacterial community), Thermoascaceae, and Phaffomycetaceae (fungal community) gradually increased; and to the best of our knowledge, there are no reports on the relationship between Thermoascaceae and Phaffomycetaceae families with salt stress. At the genus level, Salinimicrobium (bacterial community) was the dominant bacterium in the rhizosphere soil of the YDL, YDM, and YDH groups, while with the increase of salinity, the relative abundance of Byssochlamys and Wickerhamomyces (fungal community) gradually increased, and to the best of our knowledge there are no reports on the relationship between Byssochlamys and salt stress. Salinity mainly affected the bacterial community abundance, but it had little effect on the fungi community abundance. The bacterial community of the YDH group was dominated by bacteria of unknown origin (52.76%), while bacteria of unknown origin accounted for 26.46% and 20.78% of the bacterial communities in the YDM and YDL groups, respectively. The fungi community of the YDH group was dominated by YDL group fungi (relative abundance of 44.44%), followed by YDM group fungi (29.42%) and fungi of unknown origin (26.14%). These results provide a better understanding of the rhizosphere microbial diversity of saline–alkali‐tolerant plants, laying a foundation for developing a saline–alkali‐tolerant plant microbiome. Studies have shown that the microbiome of saline‐tolerant plants plays a significant role in promoting salt stress in non‐saline‐tolerant plants, but the microorganisms and their mechanisms are still unclear. In this study, the Suaeda salsa (L.) Pall. in Yellow River Delta region was selected to study the changes of microbial diversity. These results can provide valuable information for understanding the rhizosphere microbial diversity of saline–alkali‐tolerant plants, and lay a foundation for developing saline–alkali‐tolerant plant microbiome.

To achieve high‐energy‐density and safe lithium‐metal batteries (LMBs), solid‐state electrolytes (SSEs) that exhibit fast Li‐ion conductivity and good stability against lithium metal are of great importance. This study presents a systematic exploration of selenide‐based materials as potential SSE candidates. Initially, Li8SeN2 and Li7PSe6 were selected from 25 ternary selenides based on their ability to form stable interfaces with lithium metal. Subsequently, their favorable electronic insulation and mechanical properties were verified. Furthermore, extensive theoretical investigations were conducted to elucidate the fundamental mechanisms underlying Li‐ion migration in Li8SeN2, Li7PSe6, and derived Li6PSe5X (X = Cl, Br, I). Notably, the highly favorable Li‐ion conduction mechanism of vacancy diffusion was identified in Li6PSe5Cl and Li7PSe6, which exhibited remarkably low activation energies of 0.21 and 0.23 eV, and conductivity values of 3.85 × 10−2 and 2.47 × 10−2 S cm−1 at 300 K, respectively. In contrast, Li‐ion migration in Li8SeN2 was found to occur via a substitution mechanism with a significant diffusion energy barrier, resulting in a high activation energy and low Li‐ion conductivity of 0.54 eV and 3.6 × 10−6 S cm−1, respectively. Throughout this study, it was found that the ab initio molecular dynamics and nudged elastic band methods are complementary in revealing the Li‐ion conduction mechanisms. Utilizing both methods proved to be efficient, as relying on only one of them would be insufficient. The discoveries made and methodology presented in this work lay a solid foundation and provide valuable insights for future research on SSEs for LMBs. [ABSTRACT FROM AUTHOR]

Comprehensive Summary: Carbon‐based nanomaterials show great potential in selective electrochemical oxygen reduction reaction (ORR) through two‐electron (2e−) pathway for H2O2 production, which provides an eco‐friendly alternative to industrial energy‐intensive anthraquinone process. However, it still remains challenging to directly construct topological defects, which makes it difficult to study the working mechanism on 2e– ORR. Herein, we propose a precursor‐mediated chemical vapor deposition (CVD) approach for direct growth of topological defect‐rich hierarchical nanocarbons. Boric acid (H3BO3) is introduced into the precursor for disturbing the nucleation and growth through decomposing B‐containing species, which can in situ induce the formation of pentagon defects. The topological defect is found to be capable of introducing lattice strain, which can modify the electronic structure of nanocarbons and promote the key intermediate (*OOH) formation, thus greatly enhancing the 2e– ORR performance. Experimentally, the 2e– ORR selectivity shows a positive correlation to the topological defect density, where the average H2O2 selectivity reaches above 90% over a wide potential range with optimized concentration of H3BO3 as mediator. Moreover, in a flow cell, the hierarchical nanocarbons achieve a high H2O2 production rate of 998 mmol·gcatalyst−1·h−1 over 20 h of continuous electrocatalysis with stable current density (>100 mA·cm–2) and Faradaic efficiency (> 90%). This work provides a straightforward method for the synthesis of active metal‐free carbon‐based catalyst for sustainable H2O2 production. [ABSTRACT FROM AUTHOR]

- Abstract
The electrochemical CO2 reduction reaction (CO2RR) into valuable chemicals represents an effective approach for realizing carbon neutralization goals. Copper oxide‐derived catalysts are particularly promising due to their tunable electronic structures. In this study, we focused on investigating the Ag2Cu2O3 model catalyst and a mixture of CuO and Ag2O with an identical metal molar ratio (denoted an as M–CuAgO). Electrochemical CO2RR tests revealed that Ag2Cu2O3 exhibited selectivity towards ethanol, while M–CuAgO showed no selectivity towards multi‐carbon products. Characterizations of the post‐reaction materials showed differences in the specific crystal structures of the two catalysts. Further X‐ray photoelectron spectroscopy (XPS) analysis demonstrated that the Ag2Cu2O3 structure, after the reaction, facilitated the transfer of electrons from Cu to Ag, thereby promoting the formation of multi‐carbon products. This work underscores the significance of structural design in precatalysts and opens up new avenues for the design of high‐performance catalysts. [ABSTRACT FROM AUTHOR]

Advanced artificial nerve conduits offer a promising alternative for nerve injury repair. Current research focuses on improving the therapeutic effectiveness of nerve conduits by optimizing scaffold materials and functional components. In this study, a novel poly(3,4‐ethylenedioxythiophene) (PEDOT)‐integrated fish swim bladder (FSB) is presented as a conductive nerve conduit with ordered topology and electrical stimulation to promote nerve regeneration. PEDOT nanomaterials and adhesive peptides (IKVAV) are successfully incorporated onto the decellularized FSB substrate through pre‐coating with polydopamine. The obtained PEDOT/IKVAV‐integrated FSB substrate exhibits outstanding mechanical properties, high electrical conductivity, stability, as well as excellent biocompatibility and bioadhesive properties. In vitro studies confirm that the PEDOT/IKVAV‐integrated FSB can effectively facilitate the growth and directional extension of pheochromocytoma 12 cells and dorsal root ganglion neurites. In addition, in vivo experiments demonstrate that the proposed PEDOT/IKVAV‐integrated FSB conduit can accelerate defective nerve repair and functional restoration. The findings indicate that the FSB‐derived conductive nerve conduits with multiple regenerative inducing signals integration provide a conducive milieu for nerve regeneration, exhibiting great potential for repairing long‐segment neural defects.

Here, an approach to produce a hierarchical porous Fe‐N‐C@TABOH catalyst with densely accessible high intrinsic active FeNx sites is proposed. The method involves a single‐step pyrolysis of Zn/Fe‐zeolitic imidazolate framework (Zn/Fe‐ZIF‐H) with tetrabutylammonium hydroxide (TABOH) micelles, which is obtained by utilizing TABOH as a structural template and electronic mediator at room temperature for a brief duration of 16 min. Notably, the yield of Zn/Fe‐ZIF‐H is 3.5 times that of Zn/Fe‐ZIF‐N prepared by conventional method. Results indicate that in addition to expediting synthesis and increasing yield of the Zn/Fe‐ZIF‐H, the TABOH induces a hierarchical porous structure and fosters the formation of more and higher intrinsic active FeNx moieties in Fex‐N‐C@TABOH, showing that TABOH is a multifunctional template. Crucially, the increased mesoporosity/external surface area and optimized microenvironment of Fe‐N‐C@TABOH significantly enhance ORR activity by facilitating the formation of high intrinsic active FeNx sites, increasing accessible FeNx sites, and reducing mass transfer resistance. Through structure tailoring and microenvironment optimization, the resulting Fe‐N‐C@TABOH exhibits superior ORR performance. DFT calculation further validates that the synergistic effect of these two factors leads to low ORR barrier and optimized *OH adsorption energy. This study underscores the importance of structure and electronic engineering in the development of highly active ORR catalysts. [ABSTRACT FROM AUTHOR]

Aqueous zinc metal battery (AZMB) has received widespread attention due to the advantages of low cost and high safety. However, challenges of dendritic growth, hydrogen evolution reaction, and other side‐reaction impede the performance of the Zn anode. Herein, 4‐amino‐benzene‐sulfonic acid (ABSA) is proposed as an additive to the ZnSO4 electrolyte for improving the performance of AZMB. Combined analyses of theoretical calculations and experiment results, ABSA assumes a pivotal function in constructing an adsorptive layer, facilitating the subsequent formation of a stable sulfur‐rich solid‐electrolyte interphase (SEI). Consequently, the SEI layer modulates the pathway of Zn2+ electrodeposition/dissolution and effectively hinders the deleterious growth of dendrites and unwanted side reactions. As a result, the Zn||Zn cells stably cycles for 2500 h at 1 mAh cm−2/1 mA cm−2 and over 1000 h at 10 mAh cm−2/10 mA cm−2. Significantly, the pouch cell of Zn||VO2 can obtain the specific capacity of 151 mAh g−1 after 100 cycles. This work may provide a new perspective for designing advanced electrolytes from the prospect of interface protection for the AZMB and other metal ion batteries. [ABSTRACT FROM AUTHOR]

White matter (WM) functional activity has been reliably detected through functional magnetic resonance imaging (fMRI). Previous studies have primarily examined WM bundles as unified entities, thereby obscuring the functional heterogeneity inherent within these bundles. Here, for the first time, we investigate the function of sub‐bundles of a prototypical visual WM tract—the optic radiation (OR). We use the 7T retinotopy dataset from the Human Connectome Project (HCP) to reconstruct OR and further subdivide the OR into sub‐bundles based on the fiber's termination in the primary visual cortex (V1). The population receptive field (pRF) model is then applied to evaluate the retinotopic properties of these sub‐bundles, and the consistency of the pRF properties of sub‐bundles with those of V1 subfields is evaluated. Furthermore, we utilize the HCP working memory dataset to evaluate the activations of the foveal and peripheral OR sub‐bundles, along with LGN and V1 subfields, during 0‐back and 2‐back tasks. We then evaluate differences in 2bk‐0bk contrast between foveal and peripheral sub‐bundles (or subfields), and further examine potential relationships between 2bk‐0bk contrast and 2‐back task d‐prime. The results show that the pRF properties of OR sub‐bundles exhibit standard retinotopic properties and are typically similar to the properties of V1 subfields. Notably, activations during the 2‐back task consistently surpass those under the 0‐back task across foveal and peripheral OR sub‐bundles, as well as LGN and V1 subfields. The foveal V1 displays significantly higher 2bk‐0bk contrast than peripheral V1. The 2‐back task d‐prime shows strong correlations with 2bk‐0bk contrast for foveal and peripheral OR fibers. These findings demonstrate that the blood oxygen level‐dependent (BOLD) signals of OR sub‐bundles encode high‐fidelity visual information, underscoring the feasibility of assessing WM functional activity at the sub‐bundle level. Additionally, the study highlights the role of OR in the top‐down processes of visual working memory beyond the bottom‐up processes for visual information transmission. Conclusively, this study innovatively proposes a novel paradigm for analyzing WM fiber tracts at the individual sub‐bundle level and expands understanding of OR function. [ABSTRACT FROM AUTHOR]

Background: Low‐intensity pulsed ultrasound (LIPUS) combined with acupoint can promote gastric motility of diabetic rats. The switch of gastric smooth muscle cell (GSMCs) phenotype was related to the diabetes‐induced gastric dysfunction, but the mechanism is not clearly elucidated. This study was aimed at exploring the underlying mechanism of LIPUS stimulation application in diabetic gastroparesis rats. Methods: In this study, Sprague–Dawley male rats were divided into three groups: control group (CON), diabetic gastroparesis group (DGP), and LIPUS‐treated group (LIPUS). LIPUS irradiation was performed bilaterally at ST36 for 20 min per day for 4 weeks. The gastric emptying rate was measured by ultrasound examination. Contraction ability of GSMCs was assessed by muscle strip experiment. The expression of related proteins or mRNAs including α‐SMA, SM22α, MHC, RhoA, Rock2, p‐MYPT1, MYPT1, p‐MLC, MLC, MALAT1, miR‐449a, and DLL1 was detected by different methods such as western blotting, RT‐qPCR, immunohistochemistry, and immunofluorescence staining, as appropriate. Key Results: (a) LIPUS stimulation at ST36 could improve the gastric motility dysfunction of diabetic rats. (b) LIPUS increased RhoA, Rock2, p‐MYPT1, and p‐MLC expression level. (c) MALAT1 and DLL1 contents were decreased, but the level of miR‐449a was increased in the LIPUS group. Conclusions & Inferences: LIPUS may affect the contractile marker expression of gastric smooth muscle through the RhoA/Rock and MALAT1/miR‐449a/DLL1 pathway to ameliorate DGP. [ABSTRACT FROM AUTHOR]

Asymmetric electrosynthesis provides an efficient and controllable route for chiral synthesis. In comparison to traditional symmetric synthesis methods, asymmetric electrosynthesis typically operates under milder conditions, reducing waste generation and energy consumption. This aligns with the current trend in green chemistry, contributing to the development of environmentally friendly synthetic pathways. Apart from reactions initiated with chiral substrates, introducing appropriate chiral factors during the electrochemical process is crucial. In this context, chiral electrodes have garnered significant attention due to their advantages such as high catalytic activity, enantioselectivity, and reusability. This concept aims to introduce the preparation of three main types of chiral electrodes over the past decade, including chiral modified electrodes, chiral immobilized electrodes and chiral imprinted electrodes, and their applications in asymmetric electrosynthesis. The article provides insights into the current state of the field and outlines prospects for future research. [ABSTRACT FROM AUTHOR]

Comprehensive Summary: The problem of molecular diffusion in the soup of chemical reactions attracts mounting interest across fields ranging from chemistry to biophysics to material science. Chemical reactions involve bond breakup and formation, whose time scale is typically on the orders of fs to ps, while molecular diffusion occurs at time scales of μs to ms. The two processes are often considered orthogonal, given the vastly different scales. The serial results show that the enzyme's diffusion is enhanced in a substrate‐dependent manner, which was further extended to small molecule reaction systems, challenging this classical paradigm. However, the results from different groups using different techniques do not quantitatively agree, and a general mechanism is yet to be understood. We summarize experimental studies on diffusion problems and seek to reconcile the interpretation with understanding the limits of measurement tools and the chemical nature of reaction systems. Understanding molecular diffusion in chemical reactions will provide fresh thoughts in designing chemical systems such as molecular machines that harvest work at the nanoscale in a controllable manner.

With the merits of high atomic utilization and well‐defined configuration, metal−nitrogen−carbon (M−N−C) single‐atomic catalysts (SACs), show great capability in selective reduction of CO2 into CO and formate. However, the metal center with the planar configuration of M−N4 has a highly symmetric structure, which is not conductive to charge transfer, thus limiting the intrinsic activity of SACs. Introduction of axially coordinated atoms with M−N4 center can break the symmetry and optimize the intermediate adsorption for accelerating CO2 reduction. Here, we briefly discuss the CO2RR pathway on single atoms and introduce the emerging synthetic methods for SACs with axial ligands. Then we review the axial coordination effect on CO2RR behavior. This review will be helpful for understanding the working mechanism of axially coordinated single atoms for enhancing CO2RR performance and thereby designing ideal coordination ligand in the axial direction.

This article discusses a rare case of CD10-negative adult B-lymphoblastic leukemia (B-LBL) with amplification of the KMT2A gene without rearrangement. The KMT2A gene is typically associated with myeloid neoplasms but rarely occurs in B-LBL. The patient in this case was a 70-year-old female who presented with pancytopenia and was found to have a high percentage of lymphoblasts in her bone marrow. The article provides detailed information about the patient's diagnosis, including flow cytometry, karyotyping, fluorescence in situ hybridization (FISH), and genetic analysis. The article also discusses the similarities and differences between B-LBL with KMT2A amplification and B-LBL with KMT2A rearrangements. The prognosis for patients with KMT2A amplification is generally poor, and this case was no exception, as the patient passed away shortly after diagnosis. Overall, this article provides valuable information about a rare and poorly understood form of B-LBL. [Extracted from the article]

Studies in medicine, bioscience, psychology, sociology, and public health have provided various contextual, individual, and vaccine‐specific explanations for vaccine uptake. However, one significant yet often ignored fact is that vaccination could be viewed as a site of citizen‐state interaction in implementing public vaccination policy. This begs the questions: What barriers create administrative burdens in vaccination? How do the experiences of administrative burdens (i.e., the learning, psychological, and compliance costs in citizen‐state interactions) shape the public's willingness to vaccinate? According to theoretical insights drawn from the extant literature on administrative burden and vaccine uptake, this study uses a conjoint experiment design based on a representative sample of China to reveal the role of administrative burdens in shaping the public's willingness to vaccinate against the monkeypox outbreak, a 'Public Health Emergency of International Concern' from July 2022 to May 2023. The experimental results suggest that multiple salient barriers have distinct effects on the respondents' learning, psychological, and compliance costs, thus significantly influencing their vaccine uptake. These findings have important implications for both future research and efforts to promote mass immunization programs. [ABSTRACT FROM AUTHOR]

Aim: To analyse the factorial structure and psychometric properties of the Chinese Short‐Form Five Facets of Mindfulness Questionnaire (FFMQ‐SF) among nursing students in the Chinese mainland. Design: A cross‐sectional study. Methods: A total of 240 undergraduate nursing students were recruited from a school of nursing in Beijing, China from 25 to 30 April 2021. FFMQ‐SF and Depression‐Anxiety‐Stress Scale were used to collect information on the mindfulness level and mental health status of the study participants. Descriptive analyses were performed to examine the demographic characteristics. Confirmatory factor analyses (CFAs) were used to test the structural, convergent and discriminant validity of the scale model. Pearson correlation analysis was used to test the correlation between the variables and the criterion validity. Results: The overall fit of the scale model is good (Bollen–Stine χ2 = 177.206, df = 142, GFI = 0.923, AGFI = 0.883, TLI = 0.980, CFI = 0.983, RMSEA = 0.032, SRMR = 0.090). One‐factor models using CFA demonstrated the overall best fit for four out of five subscales of the FFMQ‐SF. In the five‐factor CFA of the FFMQ‐SF, the composite reliability values of the five factors were from 0.685 to 0.870 and the values of average variance extracted were from 0.426 to 0.627. Patient or Public Contribution: The students who participated in this study contributed to the advancement of knowledge on mindfulness and mental health among nursing students in China. They voluntarily completed the online questionnaires and provided their honest and valid responses. Their data was used to evaluate the psychometric properties of the FFMQ‐SF and to examine the relationship between mindfulness and psychological problems. Their feedback also helped to improve the quality and applicability of the FFMQ‐SF instrument for future research and practice. [ABSTRACT FROM AUTHOR]

SUMMARY: Bermudagrass (Cynodon dactylon) is a globally distributed, extensively used warm‐season turf and forage grass with high tolerance to salinity and drought stress in alkaline environments. However, the origin of the species and genetic mechanisms for salinity tolerance in the species are basically unknown. Accordingly, we set out to study evolution divergence events in the Cynodon genome and to identify genes for salinity tolerance. We developed a 604.0 Mb chromosome‐level polyploid genome sequence for bermudagrass 'A12359' (n = 18). The C. dactylon genome comprises 2 complete sets of homoeologous chromosomes, each with approximately 30 000 genes, and most genes are conserved as syntenic pairs. Phylogenetic study showed that the initial Cynodon species diverged from Oropetium thomaeum approximately 19.7–25.4 million years ago (Mya), the A and B subgenomes of C. dactylon diverged approximately 6.3–9.1 Mya, and the bermudagrass polyploidization event occurred 1.5 Mya on the African continent. Moreover, we identified 82 candidate genes associated with seven agronomic traits using a genome‐wide association study, and three single‐nucleotide polymorphisms were strongly associated with three salt resistance genes: RAP2‐2, CNG channels, and F14D7.1. These genes may be associated with enhanced bermudagrass salt tolerance. These bermudagrass genomic resources, when integrated, may provide fundamental insights into evolution of diploid and tetraploid genomes and enhance the efficacy of comparative genomics in studying salt tolerance in Cynodon. Significance Statement: We have successfully sequenced the first heterozygous, tetraploid genome of Cynodon dactylon, a key warm‐season turfgrass and forage crop. Our GWAS analysis has identified genes linked to vital agronomic traits, enhancing our understanding of bermudagrass cultivation. [ABSTRACT FROM AUTHOR]

Background: The current study reported a case with a history of neuroradiculitis. Within 2 months of the COVID‐19 vaccine, critical Guillain‐Barre Syndrome (GBS) appeared after acute diarrhea, progressive myasthenia, and sudden respiratory and cardiac symptoms. Methods: The syndrome was addressed with measures, such as endotracheal intubation and cardiopulmonary resuscitation vasoactive drugs. Next, we conducted six cycles of human immunoglobulin treatment (dose of 400 mg/kg·d intravenously for 5 days consecutively) and three times plasma exchange (PE, 30 ml/kg), followed by methylprednisolone sodium succinate. Rehabilitation training was carried out continuously. Results: The consciousness of the patient returned to normal, wherein he carried out normal communication. The muscle strength recovered gradually but still could not stand independently. Presently, he is recovering at home. Conclusions: For patients with previous radiculitis, COVID‐19 vaccination may increase the susceptibility to GBS. Thus, it is recommended to extend the vaccination interval for these patients and ensure that any potential increased risk is continually assessed. [ABSTRACT FROM AUTHOR]

Purpose: Lung cancer (LC) and breast cancer (BC) are the most common causes of brain metastases (BMs). Time from primary diagnosis to BM (TPDBM) refers to the time interval between initial LC or BC diagnosis and development of BM. This research aims to identify clinical, molecular, and therapeutic risk factors associated with shorter TPDBM. Methods: We retrospectively reviewed all diagnosed LC and BC patients with BM at Harbin Medical University Cancer Hospital from 2016 to 2020. A total of 570 patients with LC brain metastasis (LCBM) and 173 patients with breast cancer brain metastasis (BCBM) patients who met the inclusion criteria were enrolled for further analysis. BM free survival time curves were generated using Kaplan–Meier analyses. Univariate and multivariate Cox regression analyses were applied to identify risk factors associated with earlier development of BM in LC and BC, respectively. Results: The median TPDBM was 5.3 months in LC and 44.4 months in BC. In multivariate analysis, clinical stage IV and M1 stage were independent risk factors for early development of LCBM. LC patients who received chemotherapy, targeted therapy, pulmonary radiotherapy, and pulmonary surgery had longer TPDBM. For BC patients, age ≥ 50 years, Ki67 ≥ 0.3, HER2 positive or triple‐negative breast cancer subtype, advanced N stage, and no mastectomy were correlated with shorter TPDBM. Conclusions: This single‐institutional study helps identify patients who have a high risk of developing BM early. For these patients, early detection and intervention could have clinical benefits.

Image recognition is the key to smart logistics systems. Traditional handwriting feature extraction is difficult to meet the requirements of image recognition. Deep learning is used for image recognition. Firstly, convolutional neural network (CNN) and deep Boltzmann machines under deep learning are introduced. Second, cellular neural networks are used to perform feature recognition and extraction on images. Finally, a Parzen classifier is used to classify the obtained image features. The novelty is that through the structural design and research of the intelligent logistics system, the CNN is combined to construct a management system of supply chain logistics of image recognition and information processing. The experimental results show that the recognition accuracy time of the proposed improved fusion algorithm on the Mixed National Institute of Standards and Technology data set is 198.85 s. When the improved algorithm achieves the same recognition accuracy, it takes 159.65 s. The recognition efficiency of the improved algorithm is 19.71% higher than that of the unimproved algorithm. In addition, when the unimproved algorithm reaches the maximum number of iterations, the error rate is 2.47%. The error rate of the improved algorithm is only 0.74%. This study provides a basis for improving the image recognition accuracy and has certain practical value. [ABSTRACT FROM AUTHOR]

Film mulching and biochar have been applied as effective measures for increasing crop yields in arid and semi‐arid areas for many years. However, the effects of the temporal and spatial distributions of soil hydrothermal properties on crop yields are still unclear under film mulching and biochar addition. Thus, we conducted a field experiment with winter wheat on the Loess Plateau of China for two years (2020–2022) with three treatments: control, film mulching, and biochar. The results demonstrated that film mulching and biochar addition increased the average soil temperature in the 0–50 cm soil depth throughout the whole growth period and the influence depth exceeded 50 cm. Biochar addition only significantly increased soil temperature in the overwintering stage (p < 0.05). Film mulching increased the maximum and minimum temperatures in the 0–50 cm soil depth at seedling stage. Film mulching and biochar increased average ≥10°C accumulated soil temperature by increasing the ≥10°C accumulated soil temperature in the daytime and nighttime, and the number of days with a daily soil temperature ≥10°C during the whole growth period. Film mulching improved soil water storage in the 0–300 cm soil depth in each growth stage during both years, and also increased the wheat grain yield, aboveground biomass, and water use efficiency. Biochar addition increased the wheat grain yield and aboveground biomass of two years compared with control, but the increases were not significant (p > 0.05). In addition, correlation analysis showed that adequate temperatures in the 0–50 cm soil depth during the seedling and overwintering stages, and suitable soil moisture conditions in the 0–300 cm soil depth before sowing, jointing, and filling stages were important factors for increasing wheat grain yields under film mulching. In summary, film mulching mainly regulated the soil temperature in the 0–50 cm soil depth and moisture conditions in the 0–300 cm soil depth during different growth stages to increase grain yields. Film mulching has more obvious effects on moisture regulation, temperature regulation, and yield increases than biochar addition. Some environmentally friendly measures (such as conservation agriculture) with the same yield improving effect as mulching are also recommended to explore and promote in theLoess Plateau region.

Eutrophication of freshwater ecosystems is a global problem, but restoration can be difficult due to ongoing problems relating to water pollution, sedimentary nutrient stores and altered aquatic biodiversity. Mitigation of Eutrophication is often conducted alongside transplantation of submerged macrophytes and dredging, but knowledge of ecosystem response to post‐dredging transplantation of submerged macrophytes is limited.We report a long‐term (2008–2018) in situ monitoring study to evaluate the effects of different restoration measures: dredging only (Dredged) and dredged with post‐transplantation of submerged macrophytes (Dredged with macrophytes) conducted in five subtropical eutrophic lakes, Taihu basin. Water and sediment nutrients, bloom‐forming algae Microcystis and macroinvertebrate were monitored every 2 years for each treatment and compared with reference areas (Control) established in unrestored parts of the same lake.Dredging only decreased sediment nutrients (e.g. carbon, phosphorus) significantly; however, this effect diminished about 5 years later. Dredged with macrophytes had a stronger, longer lasting positive effect on water quality than dredged alone. Disturbance caused by dredging (without macrophytes transplantation) decreased the biomass of Microcystis, while transplantation of macrophytes shortly after dredging did not contribute to the decreasing of Microcystis biomass. The biomass of Microcystis in Dredged with macrophytes areas was always similar to Control over the period of our monitoring.A positive effect of submerged macrophytes transplantation post‐dredging was found for macroinvertebrate abundance and diversity: Dredged with macrophytes areas had significantly higher macroinvertebrate biomass and richness than Dredged areas after 9 years' recovery. Macroinvertebrate richness in Dredged with macrophytes areas nearly doubled compared to Control, while Dredged areas were just restored to Control levels.Synthesis and applications: Our study provides an long‐term field monitoring with new findings about the benefits and caution of submerged macrophytes transplantation post‐dredging and the effect of partial restoration, which could inform eutrophic waterbody restoration schemes.

Social insects are prone to pathogen infection because of high exposure rates from social interactions. However, it remains unclear whether queens have enhanced pathogen resistance, because reproduction is largely confined to queens. Here, we used a natural host–pathogen system, the subterranean termite Reticulitermes chinensis and the entomopathogenic fungus Metarhizium anisopliae, to investigate the differences in allogrooming, locomotion, and immune gene expression between queens and workers against pathogen infection. We found that fungal infection significantly reduced survival in both queens and workers. Infected queens received significantly more grooming time from sanitary nestmates than infected workers, but they returned much less grooming time to sanitary nestmates than infected workers. Infection resulted in a reduction in the average locomotion speed and distance of queens but had no effect on worker locomotion. Infection resulted in upregulated expression of two immune genes (termicin and transferrin), two antioxidant genes (CAT and SOD), and phosphate genes CYP450 in queens but not in workers. Our results indicated that eusocial termites evolved strategies that prioritize the reproductive castes' welfare in defending against the pathogen infection to ensure continued reproduction and colony persistence.

CuSbSe2 is a promising light‐harvesting material for solar cells, which shows advantages including low melting point, low cost, and environmental friendliness, as well as excellent optoelectronic properties. In this work, a three‐source co‐evaporation method is employed to deposit CuSbSe2 thin films for the first time. Well‐crystallized and pure‐phase CuSbSe2 films are obtained through a two‐stage co‐evaporation, and the reaction mechanism of CuSbSe2 is revealed based on the phase evolution during film deposition process. It is also found that the growth atmosphere during the high‐temperature stage of co‐evaporation deposition exerts a significant impact on the phase, composition, crystallinity, and optoelectronic properties of CuSbSe2 films. Eventually, a Mo/CuSbSe2/CdS/ZnO:Al (AZO)/Ag‐structured solar cell is successfully constructed, yielding a considerable power conversion efficiency of 1.83%. [ABSTRACT FROM AUTHOR]

Colloidal crystals are materials self‐assembled from the colloidal nanoparticles. Due to the ordered microstructure, they exhibit significant optical properties and have shown huge potential in the field of biosensing. Besides, the unique macroscopic shapes can also play a critical role in the sensing process. Here, we present a comprehensive discussion on the colloidal crystal‐based biosensors with different topological shapes, including the development strategies of currently reported colloidal crystal particles, films, and fibers, and their recent progress in biosensing. In addition, the faced challenges and the possible solutions are also concluded and discussed. We expect this review can enrich the knowledge and encourage the communication of interdisciplinary researchers, thus promoting the further development and practical applications of colloidal crystal‐based biosensors.

The improvement of optical absorption behavior of the second near‐infrared region (NIR‐II, 1000–1350 nm) based on new function materials is significant for the development of biomedicine and optical imaging. Therefore, the electronic structures and optical absorption of 2H phase MoS2 doped by F, Cl, Br, and I atoms with various doping concentrations are calculated, results show that halogen elements introduced extra transition allowed bands which is about 1.0 eV wide to 2H‐MoS2, and the increasing of impurity concentration can trigger strong spin splits. The transformation of electronic structures leads to 2H‐MoS2 metallic behaviors, improves transition efficiency, and lowers photon energy loss. More importantly, strong light–mass interaction is verified and breaks the energy level degeneracy, makes absorption peaks at 0.6–1.0 eV photon energy region, successfully extends the work region of 2H‐MoS2 to NIR‐II window, greatly improves the optical response and application potential in the photoelectric field. These results not only prove the potential of halogen elements as dopants in bandgap engineering of 2H‐MoS2 but also may indicate a direction for seeking new generation function materials that own excellent performance in the NIR‐II window, which is of great significance to promote the development of optoelectronics and bioimaging applications.

Eucalyptus is a widely planted hardwood tree species due to its fast growth, superior wood properties and adaptability. However, the post‐transcriptional regulatory mechanisms controlling tissue development and stress responses in Eucalyptus remain poorly understood. In this study, we performed a comprehensive analysis of the gene expression profile and the alternative splicing (AS) landscape of E. grandis using strand‐specific RNA‐Seq, which encompassed 201 libraries including different organs, developmental stages, and environmental stresses. We identified 10 416 genes (33.49%) that underwent AS, and numerous differentially expressed and/or differential AS genes involved in critical biological processes, such as primary‐to‐secondary growth transition of stems, adventitious root formation, aging and responses to phosphorus‐ or boron‐deficiency. Co‐expression analysis of AS events and gene expression patterns highlighted the potential upstream regulatory role of AS events in multiple processes. Additionally, we highlighted the lignin biosynthetic pathway to showcase the potential regulatory functions of AS events in the KNAT3 and IRL3 genes within this pathway. Our high‐quality expression atlas and AS landscape serve as valuable resources for unravelling the genetic control of woody plant development, long‐term adaptation, and understanding transcriptional diversity in Eucalyptus. Researchers can conveniently access these resources through the interactive ePlant browser (https://bar.utoronto.ca/eplant_eucalyptus). Summary statement: We provide a dataset on gene expression and alternative splicing in Eucalyptus tissues across various developmental stages, stress conditions, and hormone treatments. It was integrated into the interactive ePlant browser, providing a valuable resource for understanding the transcriptional and post‐transcriptional regulation of woody plants. [ABSTRACT FROM AUTHOR]
