Biodiversity‐driven spatial conservation planning to delineate temporally stable regions

open access: yesConservation Biology, EarlyView.
Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis

open access: yesVeterinary Dermatology, EarlyView.
ABSTRACT Background Ichthyosis fetalis (IF), also known as harlequin ichthyosis, is a rare and often fatal autosomal recessive congenital skin disorder. It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears.

Tolerability and Feasibility of Minimally Invasive Canine Skin Sampling: Excellent Tolerability Meets Transcriptomic Challenges

open access: yesVeterinary Dermatology, EarlyView.
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 ...

Effect of Worm‐Like Amorphous Phase on Corrosion Resistance and Antibacterial Properties of NiTiCu Alloy

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT By adding CuO, the worm‐like amorphous phase and atomic clusters were simultaneously introduced, enabling the (Ni40Ti40Cu20)99.9O0.1 alloy micron columns to exhibit a uniform flow strain of over 40% and a strength of over 2.5 GPa during compression.

Interleaved High Step-Up Current Auto-balance DC/DC Converter In The Photovoltaic Generation System And Its Paralleled Operation [PDF]

open access: yes, 2016
随着能源和环境问题的日益加剧,光伏电池等新能源并网发电技术得到广泛关注。在光伏并网发电系统中,如何把较低的光伏电池电压转换成并网用的标准母线电压,已成为了重要的研究课题。 本文提出了一种新颖的带耦合电感和开关电容的电流自动平衡高增益DC-DC变换器,该变换器采用耦合电感和开关电容来提升电压增益,同时,主开关管的电压应力大大降低。由于该变换器拓扑具有交叉耦合结构,变换器具备优良电流自动平衡能力。利用交错式操作方式使得输入电流纹波和输出电压纹波都大大减少。此外,在耦合电感的漏感的作用下,开关管实现零电流开通、

Bi/Bi2O3 Nanoparticles In Situ Embedded in Carbon as Anode Materials for Fast and Long‐Lasting Sodium–Ion Storage

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Bismuth anode materials are considered promising anode candidates for sodium–ion batteries (SIBs) due to their high theoretical capacity and appropriate working potential. Nevertheless, the significant volume expansion that occurs during the cycling process restricts its broader application in sodium–ion storage. Herein, Bi/Bi2O3 nanoparticles

In Situ Formation of the Li3Bi Alloy Phase Interface for Robust Garnet Solid‐State Lithium Batteries

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Garnet‐type electrolyte Li6.4La3Zr1.4Ta0.6O12 (LLZTO) is a promising component for commercializing solid‐state batteries owing to its wide electrochemical window, good stability, and high shear modulus. However, poor interface wettability and lithium dendrite growth limit the practical application of the LLZTO electrolyte.

石羊河流域出山口河流流量的变化趋势及特性分析

open access: yesShuitu Baochi Xuebao, 2011
根据相关水文气象台站的降水、蒸发、气温和流量观测资料,分析了石羊河流域年平均流量的变化特征及原因.研究表明:45 a来,石羊河流域年平均流量总体呈略减少趋势,流域东、中部年平均流量呈减少趋势,流域东部减少幅度最大,流域西部年平均流量呈略增加趋势.石羊河流域年平均流量的年内分配因受补给条件的影响四季分明,四季流量大小依次为夏季、秋季、春季、冬季.流域四季年平均流量都呈减少趋势,变幅最大的是夏季,冬季最小.石羊河流域在不同时段不同区域年平均流量都存在6~7 a和9~10a的长周期和2~3 a的短周期 ...
