Risk of Secondary Extinction in the Asian Songbird Trade, as Exemplified by the Selling of Crested Jayshrikes as Master Birds

Integrative Conservation, Volume 5, Issue 1, Page 33-45, March 2026.
The Asian Songbird Crises negatively affects so‐called master birds, species that are used to increase the song complexity of competitive songbirds. We assessed the trade in a master bird, the crested jayshrike, in Indonesia before and after its legal protection.

Configuration Optimization Design of Magnetic Circuit for Large Magnetostrictive Devices Based on TbDyFe Alloy

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Reliable operation of high‐performance magnetostrictive devices, composed of the giant magnetostrictive material (GMM), that is, the TbDyFe alloy, critically depends on an optimally tailored bias magnetic field. Sufficient intensity and uniformity are essential to induce the ideal initial strain in the GMM, enabling peak reciprocating output ...

Fermi Surface Structure Revealed by Quantum Oscillations in Half‐Heusler Semimetal LuAuSn

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The Fermi surface structure in the half‐Heusler semimetallic compound LuAuSn was systematically investigated using quantum oscillation studies of high‐quality single crystals and first‐principles calculations. Clear bulk quantum oscillation signals were observed for multiple complementary physical properties, including magnetization, Hall ...

Multiscale Study of a Synergistic System in Carbon‐Coated Multimetal‐Based Selenides Toward Rapid and Highly Stable Sodium Storage

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The development of sodium‐ion batteries (SIBs) is limited by slow charge transfer kinetics and large material volume changes caused by the large radius of Na+. Leveraging the excellent physicochemical properties and unique heterostructures of metal selenides, ultrafine hetero‐CuFeSe2‐CoSe2 nanoparticles are in situ wrapped by ...

Dual Synergistic Effects in a Ce‐Modified MnO2/MnO Heterostructure Enabling Outstanding Acidic Oxygen Evolution

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The development of highly efficient and stable nonprecious metal electrocatalysts for the acidic oxygen evolution reaction (OER) is crucial to advance proton exchange membrane (PEM) water electrolysis. In this work, a dual synergistic strategy was proposed by constructing a Ce‐modified MnO2/MnO heterostructure.

Highly Anisotropic TbCo11Ti: Phase Evolution, Microstructure and Magnetic Properties

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Among the 1:12‐type compounds, TbCo11Ti stands out due to its high Curie temperature and pronounced magnetocrystalline anisotropy. However, its magnetic behavior at room temperature and its phase evolution process have not been clearly established.

How Vaccine Mandates Emerged Without a Mandate: Testing Stream Independence in Vietnam's COVID‐19 Response

Review of Policy Research, Volume 43, Issue 2, March 2026.
ABSTRACT This study adapts the Multiple Streams Framework (MSF) to explore why COVID‐19 vaccine mandates were applied at sectoral and subnational levels in Vietnam while the central government maintained that vaccination was voluntary. Document analysis reveals that these mandates arose from the effective coupling of the three streams—problem, policy ...

Tantalum‐Driven Interfacial Reconstruction Enables Ultra‐Low Contact Resistance in TiAlTa/Au GaN HEMTs

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT The transformative potential of gallium nitride high electron mobility transistors (GaN HEMTs) in advancing carbon‐neutral power systems remains bottlenecked by contact resistance (Rc) at the metal–semiconductor (M‐S) interface, a critical determinant of switching losses and frequency response.

±800kV输电线路带电作业电场仿真分析

Gaoya dianqi, 2017
为了确保±800 kV特高压直流输电线路带电作业过程中线路和作业人员的安全。文中运用Ansoft软件建立了杆塔、绝缘子、线路以及人体的仿真模型,并用有限元分析法对带电作业人员以不同方式进入等电位过程中典型位置的体表场强进行了计算。计算结果表明:采用双人直立式沿绝缘子串进入等电位作业,人移动至绝缘子1/4处时的体表场强约为515 kV/m,当人移动至绝缘子1/2处时的人体体表场强约为1030 kV/m;采用吊篮法进入等电位作业,带电作业人员位于杆塔上地电位作业时,作业人员较安全,吊篮移动至距屏蔽环3 ...

Bifunctional Competitive Structure of Biomass Carbon‐Derived Metacomposites for Tunable ε′‐Near‐Zero and ε′‐Negative Responses

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Regulating negative parameters of metacomposites is mainly limited by their unclear mechanisms, which affects their practical applications in new sensing, communication, electromagnetic (EM) protection and other fields. This work proposes a dual‐functional competitive design strategy based on the waste corncob‐derived carbon/polyaniline ...
