Veterinary Dermatology, Volume 37, Issue 3, Page 375-385, June 2026.ABSTRACT Background Advances in transcriptomics have driven the demand for minimally invasive, reproducible and high‐yield skin sampling methods, particularly for studying inflammatory skin diseases in companion animals. Hypothesis/Objectives We tested tolerability, feasibility and RNA quantity and quality of three minimally invasive skin sampling ...

Dimensional Assembly Engineering of Ce‐MOF Interfaces for Selective Recognition of Phytic Acid
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Selective molecular recognition is central to chemical sensing yet discriminating structurally similar molecules at complex interfaces remains challenging. Traditional strategies based on tuning size, charge, or binding‐site chemistry often suffer from limited flexibility.

四川大学学报. 自然科学版, 2010 应用密度泛函B3P86方法,对H（D）、C、O采用6-311++G**,对Pd采用相对论有效势SDD基集合进行理论计算,得到PdH（PdD）、PdCO、H2、D2、CO等分子的平衡几何和离解能.利用电子-振动近似理论,分别计算了在不同温度下Pd与氢、Pd与氘、以及Pd与CO反应的平衡常数及平衡分压.进而利用同时反应的热力学理论,研究Pd与H2、D2、CO同时反应的平衡组份、平衡分压力及其排代效应和相互耦合竞争效应.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The protracted incubation time has long been the Achilles' heel of the promising 2LiBH4–MgH2 hydrogen storage system. Instead of the usual route‐creating heterogeneous nucleation sites to hasten MgB2 formation, we shortened both de‐ and re‐hydrogenation incubation periods by steering the Mg transformation itself.

四川大学学报. 自然科学版, 2014 针对加权复杂网络中的社区结构发现问题,本文定义基于权重关系的相似度,并在此基础上定义了节点中心度和归属度,改进GN算法的模块度评价函数,提出一种基于相似度的中心聚类算法(SCC).该算法通过计算节点间的相似度,选取合理的中心度大的节点作为社区中心节点,最后基于节点归属度来聚集从而形成社区;同时,提出了用相似度代替边介数的改进GN算法SGN.通过理论分析,并在数据集上进行实验验证,结果表明SCC算法与WGN算法、SGN算法相比,速度和精度上均有较大改善.同时与I2C算法相比,社区的划分有效性更好.

A kinetic model for bedload transport(推移质运动的动力学模型)
Zhejiang Daxue xuebao. Lixue ban, 2001 近底水流中推移质的输移属于固液二相流问题.本文针对固相推移质具有的随机和力学双重特性，通过类似分子运动论中Boltzmann方程的推导方法，建立起推移质运动的控制微分方程，其中碰撞项主要考虑推移层颗粒与床而层颗粒的碰撞效应.据此获得推移质输移问题的固液二相流模型——动力学模型，将推移质通量与所受外力联系起来，便于揭示推移质运动的力学本质，开辟推移质理论研究的新途径.

Strengthening community‐based fisheries monitoring programs with Indigenous perspectives
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Community‐based monitoring (CBM) programs are increasingly recognized as essential for adaptive environmental stewardship. Yet, the CBM literature often highlights successful cases and privileges evaluations by external experts over those of community members themselves.

四川大学学报. 自然科学版, 2009 利用全量子理论,精确求解了非旋波近似下多个二能级原子与单模光场构成的联合系统态矢量的演化规律,讨论了旋波近似下和非旋波近似下纠缠态在光场与原子之间的转化过程。结果表明:旋波近似下,原子纠缠态与光场纠缠态可以方便的交换传递或保持。非旋波近似下,虚光场效应对纠缠态在腔场与原子之间相互转化的过程有明显的影响:光场纠缠信息传递给原子后腔场未能恢复到真空态;伴随着纠缠态的转化和保持过程,相位有所改变并产生了多项干扰。

Automating the analysis of public saliency and attitudes toward biodiversity from digital media
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Measuring public attitudes toward wildlife provides crucial insights into human relationships with nature and helps monitor progress toward Global Biodiversity Framework targets. Yet, conducting such assessments at a global scale presents challenges.
