Leaf Hydraulic Conductance Mediates the Effect of Precipitation on Leaf Nutrients in Subtropical Forests

Zhimin Li, Zhaofeng Chang, Conghui Guo, Huiying Lin et autres

ABSTRACT Precipitation will increase in some regions and decrease in others. These changes can alter plant nutrient status, and consequently, impact the terrestrial carbon cycle. However, the ecological and physiological mechanisms underlying plant nutrient responses to changes in precipitation remain poorly understood. …

Leaf C:P ratio as a universal indicator of photosynthesis in subtropical woody species: Stoichiometric thresholds and metabolic trade‐offs

Minghao Chen, Yahong Zheng, 蔡敏玲, Songbo Tang et autres

Abstract The stoichiometric ratios of carbon (C), nitrogen (N) and phosphorus (P) serve as important indicators for assessing nutrient balance in forest ecosystems, but their relationships with photosynthetic dynamics require deeper characterization. This study systematically examined the associations between leaf C‐N‐P stoichiometry …

CVE-Factory: Scaling Expert-Level Agentic Tasks for Code Security Vulnerability

Xianzhen Luo, Jingyuan Zhang, Shiqi Zhou, Rain Huang et autres

Evaluating and improving the security capabilities of code agents requires high-quality, executable vulnerability tasks. However, existing works rely on costly, unscalable manual reproduction and suffer from outdated data distributions. To address these, we present CVE-Factory, the first multi-agent framework to achieve expert-level …

Global change reshapes glomalin‐mediated soil carbon sequestration by influencing plant inputs

Xianzhen Luo, Lingling Zhang, Hans Lambers, Akhter B. Hossain et autres

Abstract Glomalin‐related soil protein (GRSP), a by‐product of arbuscular mycorrhizal fungi (AMF), plays a crucial role in stabilizing soil organic carbon (SOC). Global change factors (GCFs) such as elevated atmospheric carbon dioxide (CO 2 ), climate warming and anthropogenic nitrogen (N) input …

Divergent Shifts in Soil Nutrient Stoichiometry and Microbial Quotient From Topsoil to Subsoil After Forest Conversion

Rui Zhang, Lingling Zhang, Rufeng Guo, Dazhi Wen et autres

ABSTRACT Soil microbial quotient (qMB), representing the proportion of soil elements contained within microbial biomass, is a critical indicator of microbial community efficiency in regulating soil quality and nutrient cycling. Changes in qMB are vital for ecosystem functioning and maintenance of soil …

From Code Foundation Models to Agents and Applications: A Comprehensive Survey and Practical Guide to Code Intelligence

Jian Yang, Xianglong Liu, Weifeng Lv, Ken Deng et autres

Large language models (LLMs) have fundamentally transformed automated software development by enabling direct translation of natural language descriptions into functional code, driving commercial adoption through tools like Github Copilot (Microsoft), Cursor (Anysphere), Trae (ByteDance), and Claude Code (Anthropic). While the field has …

Automated Snippet-Alignment Data Augmentation for Code Translation

Zhiming Zhang, Qingfu Zhu, Xianzhen Luo, Yixuan Wang et autres

Code translation aims to translate the code from its source language to the target language and is used in various software development scenarios. Recent developments in Large Language Models (LLMs) have showcased their capabilities in code translation, and parallel corpora play a …

How Many Code and Test Cases Are Enough? Evaluating Test Cases Generation from a Binary-Matrix Perspective

Xianzhen Luo, J. C. Huang, Wenzhen Zheng, Qingfu Zhu et autres

Evaluating test cases automatically generated by Large Language Models (LLMs) is a critical yet challenging task. Existing benchmarks often evaluate the exclusion ratio on large, unstructured collections of wrong codes, suffering from high computational costs and score inflation. Furthermore, they inadvertently reward …
