Seeing Is Coding: On the Effectiveness of Vision Language Models in Code Understanding

Large Language Models (LLMs) have achieved remarkable success in source code understanding, yet as software systems grow in scale, computational efficiency has become a critical bottleneck. Currently, these models rely on a text-based paradigm that treats source code as a linear...

Free‐Running Single‐Cavity Dual Combs With Hz‐Level Relative Linewidth

ABSTRACT Single‐cavity dual‐comb lasers provide a compact and efficient source for dual‐comb spectroscopy in gas sensing applications; however, achieving sufficient free‐running mutual coherence for comb‐line‐resolved, high‐resolution measurements remains challenging. Here, we pr...

An Empirical Study of False Negatives and Positives of Static Code Analyzers From the Perspective of Historical Issues

Static code analyzers are widely used to help find program flaws. However, in practice the effectiveness and usability of such analyzers is affected by the problems of false negatives (FNs) and false positives (FPs). This paper aims to investigate the FNs and FPs of such analyzer...

Chiral Arylthiol-Catalyzed Asymmetric Hydrodifluoroalkylation of Alkenes Facilitated by Noncovalent Interaction

Abstract Chiral gem-difluorinated indane scaffolds are valuable fluorinated bioisosteres of medicinally important CH2-containing indane frameworks. Herein, a photodriven enantioselective hydrodifluoroalkylation of methyleneindanes with α-bromodifluoroamides catalyzed by a C2-symm...

The Sino-Soviet Alliance, the Korean War, and the Predicament of the CCP’s Attack Plans for Taiwan, 1949–50

Abstract Drawing on archival materials from the Republic of China (Taiwan), the People’s Republic of China (PRC), the United States, and the former Soviet Union, this article discusses why the PRC’s 1949–50 strike plans for Taiwan went unfulfilled. What prevented the Chinese Comm...

Associations Between Climate Conditions and the Spatial Patterns of Construction Land in China, 2000–2020

This study examines the spatial associations between climatic conditions and construction land in China during 2000–2020. Using construction land data from CNLUCC and spatially interpolated meteorological data, five climatic indicators were selected: annual mean temperature, annu...

Biomimetic Fe(Pytacn)-Catalyzed Intramolecular C(sp3)–H Amination: Access to Heteroarene-Functionalized Sultams

Abstract A new Fe(Pytacn)-catalyzed intramolecular aliphatic C(sp3)–H amination system is reported for the first time via metal-nitrene-mediated C–H insertion. This protocol operates under mild room-temperature conditions, affording 20 structurally diverse sultams in up to 90% yi...

Photoelectrochemical Fiber Cytometry With 60 nm Tip Size for Measuring Serotonin Dynamics at Edges of Cleft and Varicosities

ABSTRACT Tools and methods for investigating neurotransmitter dynamics at synaptic and nonsynaptic varicosities are essential for deciphering neural signaling events. Here, we first built a photoelectrochemical fiber cytometry with a tip size down to ∼60 nm for real‐time collecti...

Does copula choice matter for FX tail risk hedging?

Among the eight representative specifications considered, the choice of copula in foreign exchange (FX) tail-risk hedging involves a trade-off: symmetric copulas such as the Student-t may be misspecified when tail dependence is asymmetric, but flexible asymmetric copulas add para...

A Dual‐Driven Hydrogel Actuator With Programmable Driving Force Enabled by a Shape‐Memory Scaffold and Ion‐Regulated Internal Force Reservoir

ABSTRACT Programmable soft actuators require independent control over both deformation pathways and driving‐force output, yet conventional shape‐memory systems generally encode these functions within a fixed network and therefore exhibit predetermined recovery behavior. Herein, w...

Cultivated relationality: a cross-cultural philosophical dialogue on anthropocentrism in environmental education

Environmental Education (EE) continues to grapple with anthropocentric assumptions that reduce nature to a resource domain, despite decades of advocacy for holistic, relational approaches. Michael Bonnett’s phenomenological critique offers a powerful Western philosophical challen...

Anion-Programmable Poly(Ionic Liquid) Nanocone Antennas for Tunable and Efficient Solar CO2 Photoconversion

Abstract Au/TiO2 is a promising photocatalyst for CO2 reduction, yet its performance is often limited by inefficient light utilization and insufficient local CO2 availability. Here, we present an integrated photocatalytic platform by embedding Au/TiO2 nanoparticles within imidazo...

Taxonomic revision of the genus Phryganogryllacris (Orthoptera: Gryllacrididae) from China

Li, Miao-Miao, Fang, Yan, Liu, Xian-Wei, Li, Kai (2014): Taxonomic revision of the genus Phryganogryllacris (Orthoptera: Gryllacrididae) from China. Zoological Systematics 39 (4): 507-519, DOI: 10.11865/zs.20140404

A wingless species of the genus Hemithyrsocera Saussure (Blattodea: Ectobiidae) from China

Zhang, Sainan, Liu, Xianwei, Li, Kai (2019): A wingless species of the genus Hemithyrsocera Saussure (Blattodea: Ectobiidae) from China. Zoological Systematics 44 (2): 123-131, DOI: 10.11865/zs.201907, URL: http://zoobank.org/31ca011d-0486-45e4-853b-8b888fc23715

ROOTS: recognizing oracle bone inscriptions via an organized tree structure

Oracle bone inscription recognition is hindered by long-tailed class distributions and strong inter-class visual similarity. Existing augmentation and re-weighting methods modify samples or optimization while retaining competition within a flat label space. We propose ROOTS (Reco...

Morphological and Physiological Resource Trade-Offs Affect the Response of Poa pratensis to Urban Shading

The shading of urban buildings and understory space has a severe impact on cold-season turfgrass urban greening. To explore the effect of shading stress on the typical cold-season turfgrass of Poa pratensis, the six shading gradients of 0% (full light, CK, 6 × 104 lux), 20% (1-la...
