Fabrication of Multicavity Hierarchically Porous Carbon Nanospheres Using Compressed CO2 for Overall Water Splitting

Abstract The rational design of efficient bifunctional electrocatalysts is crucial for overall water splitting. As a catalyst support, the multicavity hierarchically porous carbon spheres scaffold facilitates efficient electron transport and structural stability during catalysis....

The product of nonabelian simple groups and dihedral groups

Abstract Let X = G ⁢ D X=GD be a group, where 𝐺 is a nonabelian simple group and 𝐷 is a dihedral group. These groups 𝑋 are closely related to regular Cayley maps. The main theorems of this paper describes 𝑋.

The Impact of Negative Emotion on Visual Working Memory Under Excessive Cognitive Load: The Role of the Resource-Allocation Stage and Location Information

Visual working memory (VWM) enables people to temporarily store important information for use in subsequent tasks. Previous studies have indicated that a negative emotional state can influence the processing of VWM; however, the direction of this influence and its underlying cogn...

Mimicry of mantis and Selaginella from Cretaceous provides new evidence for the deep‐time co‐evolution of insects and plants

Summary Mimicry between insects and plants represents sophisticated survival strategies. Their long‐term evolutionary interactions led to mutual adaptation, creating a complex ecological symbiosis. However, the deep‐time ecological associations of mimicry between insects and plan...

Spatial-homogenized soil-surface pollen data can service as substitute for lake-surface pollen assemblage

Lake-surface pollen assemblage is the ideal modern analogue for past climate and vegetation reconstructions quantitatively based on lacustrine fossil pollen spectra. Soil-surface pollen assemblage, on the other hand, has been more widely applied due to its ready accessibility, ye...

Multifunctional Boron Nitride/Sodium Alginate Lamellar Membranes for Robust Osmotic Energy Harvesting and Thermal Management

Abstract Osmotic energy, derived from salinity-gradient-driven mixing, is a clean renewable resource that may help address energy and environmental challenges. Ion-exchange membranes incorporating two-dimensional (2D) materials are attractive for reverse electrodialysis, yet manu...

普通话文白异读的形成机制与教学启示 − 基于 2016 年《普通话异读词审音表 (修订稿)》条目

提要 普通话以北京语音为标准音, 但其语音系统并非单一共时方言的直接反映, 而是在复杂历时演变中逐步定型, 其中 “文白异读” 尤能体现多重层次的沉积与语体分工。本文以 2016 年《普通话异读词审音表 (修订稿)》为主要依据, 最终整理出普通话中常见的 23 个文白异读条目。本文在音韵学视角下, 运用历史...

A Variation of the Morris Constant Term

The Morris constant term identity is important due to its equivalence with the well-known Selberg integral. We find a variation of the Morris constant term, denoted $h_n(t)$, in the study of the Ehrhart polynomial $H_n(t)$ of the $n$-th Birkhoff polytope, which consists of all do...

Development and Engineering Application of a Vertically Installed FBG Sensor for Subgrade Strain Monitoring

Subgrade deformation under load is accumulated from the local compressive strain of each layer. Solely relying on the overall settlement monitoring at the top surface makes it difficult to reveal the internal strain distribution and the evolutionary characteristics of early damag...

Insula Grey Matter Volume Moderates the Relationship Between Emotional Intelligence and Domain‐Specific Creativity

ABSTRACT Emotional intelligence (EI) is linked to enhanced cognitive and social functioning, but its neurostructural correlates and relationship with domain‐specific creative achievement remain poorly understood. This study examined 266 young adults using the Emotional Intelligen...

Ecological fitting in a deceptive trap flower: Aristolochia gibertii recruits native drosophilid flies outside South America

Deceptive pollination, in which plants lure pollinators without offering rewards, represents a sophisticated evolutionary strategy. The trap-flowers of Aristolochia provide an excellent system to study the coordinated evolution of floral morphology, chemistry, and phenology. Howe...

Shot-location polarization and post-2018 pace stabilization in the NBA: Evidence from 21 seasons of team and shot-coordinate data (2004–2025)

NBA offenses increasingly reflect a “space-and-pace” approach, yet it remains unclear whether recent tempo changes primarily reflect long-run strategic adaptation or the 2018–19 14-second offensive-rebound shot-clock reset. We combined team-season metrics with shot-location data...

Multifunctional Defense of Achelura yunnanensis Cocoon: High-Strength Tough Silk Fiber, Biomineral Reinforcement, and Protease Degradation Resistance

Abstract Natural silks offer combinations of mechanical performance and biological functionality that synthetic materials still struggle to replicate. Here, we report the structural, mechanical, and biochemical characterization of cocoon silk from Achelura yunnanensis (Lepidopter...

Recent advances in deep learning for biological microscopy image analysis beyond segmentation

In the past decade, we have witnessed an unprecedented growth of artificial intelligence (AI) techniques for high-resolution microscopy images. More importantly, we are observing a paradigm evolution of these deep learning (DL) methods, from a post-hoc analysis tool to nowadays a...

Iron rich concretions accelerate localized degradation of marine recovered bluish white glaze

Iron-rich concretions are common on marine-recovered ceramics, but their role in glaze degradation remains poorly constrained. We combine archaeological characterization of bluish-white porcelain from the Nanhai I shipwreck with controlled replica exposures to evaluate how iron-r...

Reservoir Neuromorphic Computing Based on Spin-Orbit Coupling in an Organic Crystal Resonator

Abstract Neuromorphic computing is at the basis of the recent progress in artificial intelligence, but this progress is accompanied by an increasing demand for computational resources and power supply. Reservoir neuromorphic computing uses a nonlinear physical system to replace a...

Multi-Temporal Phenology–Spectral Feature Optimization and Decision Tree Classification for Estuarine Wetland Vegetation Mapping

Estuarine wetlands are highly dynamic ecosystems, and the vegetation serves as a critical indicator of ecological health. Accurate mapping of different vegetation types remains challenging due to spectral similarities and the high dimensionality of time-series data. This research...

Terahertz Spectroscopic Characterization of a Daidzein-Piperazine Crystalline Solid Form Prepared by Liquid-Assisted Grinding

Daidzein is a natural flavonoid with low aqueous solubility and bioavailability. The low-frequency terahertz spectroscopic characteristics and corresponding vibrational origins of the 1:1 daidzein–piperazine (DAI–PIP) crystalline system remain insufficiently explored. In this stu...

Asymmetric Response of Land Precipitation Variability Under Carbon Dioxide Removal

Abstract Precipitation variability describes fluctuations between wet and dry conditions and plays an important role in shaping hydrological extremes and their societal impacts. Using idealized carbon dioxide removal experiments from CMIP6 models, we assess how precipitation vari...

Land Transition Pathways Govern Carbon Storage Dynamics in an Olympic Host Region: A PLUS–InVEST Simulation in Yanqing District

Mega-events can accelerate land–use/land cover change (LULCC) through infrastructure development and ecological interventions, but the carbon consequences of different land transition pathways remain unclear. Using Yanqing District, a host region of the Beijing 2022 Winter Olympi...
