Green Light‐Driven, Diastereoselective Synthesis of Pentasubstituted α ‐Trifluoromethylated Pyrrolidines via a Singlet Carbene Process

Comprehensive Summary Trifluoromethylated heterocycles represent privileged structural motifs in pharmaceuticals and agrochemicals, as the incorporation of a CF 3 group significantly enhances metabolic stability, lipophilicity, and bioactivity. Among these, α ‐trifluoromethyl pyr...

Mechanism and Origins of Enantioselectivity of Rhodium‐Catalyzed [4+3] Annulation of Benzosilacyclobutenes with 7‐Oxabenzonorbornadienes

ABSTRACT Rhodium‐catalyzed asymmetric [4+3] annulation of benzosilacyclobutenes with 7‐oxabenzonorbornadienes provides an efficient route to enantioenriched seven‐membered sila‐heterocycles. In this study, density functional theory calculations were performed to elucidate the rea...

PCD-Net: prior-context collaborative learning for robust facial expression recognition under noisy labels

Abstract Noisy annotations and class imbalance commonly coexist in real-world facial expression recognition (FER), making hard but correctly labeled minority-class samples difficult to distinguish from unreliable training samples. Existing noisy FER approaches mainly improve robu...

Meta-Analysis of the Factors Influencing Straw Return Effects on Maize Yield in China

Background: Straw return, as an important practice for soil improvement and nutrient recycling, has great potential for enhancing soil fertility and crop productivity. However, its yield-enhancing effects and the major driving factors remain unclear under different ecological env...

Output Matching Model Reduction for Discrete‐Time Singular Systems With High Index

ABSTRACT In this paper, a new model order reduction approach is presented for reducing large‐scale discrete‐time singular systems with higher index. Based on the regularity of the singular system, the singular system is decomposed into a non‐singular subsystem and a singular subs...

Coupling Mechanism and Driving Paths of the Spatial Differentiation of Tourism Attractions from the Perspective of Tourist Perception—A Case Study of Xinjiang, China

As the culture and tourism industry moves toward high-quality development, tourist perception has become a core dimension for measuring that quality. Most existing work on tourism spatial differentiation still looks at the supply side, and describes the pattern of tourism attract...

Evaluating the Precision of 3D Morphological Reconstruction for Asphalt Pavement Textures via Close-Range Photogrammetry

Accurate 3D reconstruction of pavement textures is vital for assessing surface performance. This study systematically evaluates the factors influencing the precision of close-range photogrammetry for pavement texture characterization. Four typical mixtures, AC-13, AC-16, SMA-16,...

Digital Intelligence-Enabled Green Scheduling in Dynamic Job Shops: A Review

Dynamic job shops must absorb new orders, machine failures and processing time variations while operating under increasingly demanding energy and carbon constraints. In such settings, an offline schedule may become obsolete soon after release, especially when production and energ...

Transcriptome-Based Analysis of the Effects of Salt Stress on the Embryos of Hypomesus nipponensis

The increasing salinization and alkalization of inland waters in China pose a growing threat to the early developmental stages of fish. This study investigated the survival rates and transcriptomic response mechanisms of pond smelt (Hypomesus nipponensis) embryos, a species natur...

Research on the Whirling and Vibration Characteristics of Steel–Titanium Alloy Composite Drill Strings for Ultra-Deep Wells

To address whirling- and vibration-induced failures in ultra-deep well drill strings caused by high slenderness ratios and complex loading conditions, this study establishes a nonlinear dynamic finite element model for a steel–titanium alloy composite drill string. The model is d...

Greening of the Taklamakan Desert: Effects of climate change and ecological water conveyance

Oases in the Taklamakan Desert exist in an extremely arid region. Persistent droughts in the late 20th century nearly caused ecosystem collapse in the Lower Tarim River region. Since the implementation of ecological water conveyance in 2000, groundwater levels have increased, veg...

Warnings must cross borders before disasters do

On 26 August 2026, a large rock–ice collapse on Nepal’s Langtang Lirung massif initiated the Gyirong–Rasuwagadhi transboundary cascade. The disaster reveals three clocks governing mountain risk: long-term preconditioning, minute-scale physical cascading and institutional response...

Vibration model test and seismic performance evaluation of polypropylene fiber reinforced concrete lining of mountainside tunnels in Loess Plateau

Abstract Currently, tunnels are key infrastructure projects for traversing the Loess Plateau and ensuring rail connectivity. However, seismic damage surveys indicate that tunnels built along mountainsides in the Loess region suffer severe damage during earthquakes due to their lo...

Superlattice Engineering Stabilizes Bulk‐to‐Surface Microenvironment in Single‐Crystalline Ultrahigh‐Ni Cathodes

ABSTRACT Single‐crystalline ultrahigh‐Ni cathodes hold great promise for high‐energy Li‐ion batteries, but their practical adoption is hindered by sluggish delithiation kinetics and severe structural degradation. Although superlattice engineering has been established as an effect...

Low‐Temperature Sodium‐Ion Batteries: Interfacial and Bulk Perspectives on Performance Limitations and Improvement Strategies

ABSTRACT Sodium‐ion batteries (SIBs) are attractive for low‐temperature energy storage because of their low cost and abundant resources. However, their low‐temperature performance still suffers from capacity decay, severe polarization, poor cycle stability, and increased sodium‐p...

Rational A‐Site Multi‐Cation Design Enables Durable Fe‐Based Perovskite Air Electrodes for Fast Oxygen Reduction

Although Pr 0.5 Ba 0.5 FeO 3–δ (PBF)‐based perovskite cathodes are prevalent for solid oxide fuel cells (SOFCs), their practical application is hindered by Ba 2+ surface segregation, causing structural degradation, and poor CO 2 tolerance. Here, Pr 1/6 La 1/6 Nd 1/6 Ba 1/6 Sr 1/6...

Badmintonvision: a deep learning framework for automated tactical analysis in elite badminton

Tactical analysis in badminton is critical for performance optimization, yet traditional manual video review is time-consuming, subjective, and difficult to scale. Existing deep learning approaches struggle with rapid stroke recognition from single frames and require extensive la...

A novel Alhagi honey polysaccharide-Alum Pickering emulsion adjuvant enhances systemic and mucosal immunogenicity of a BVDV vaccine in calves

Mucosal surfaces are the primary barrier to infection. For pathogens like bovine viral diarrhea virus (BVDV) that invade via the intestinal mucosa, vaccines capable of inducing mucosal immunity are crucial for mounting a comprehensive immune response. In this study, a new assembl...
