Conservation Status, Decline Factors, and Strategies for Globally Endangered Musk Deer (Moschus spp.) in China 中国境内全球濒危麝属 (Moschus spp.) 物种的保护现状、致危因素及应对策略

open access: yesWildlife Letters, EarlyView.
This review summarizes the status of musk deer in China, highlighting severe population declines due to illegal hunting and habitat loss, and proposes integrated conservation strategies including habitat protection, captive breeding, and law enforcement to support the recovery and sustainable management of this ecologically and economically important ...

N‐Heterocyclic Tetrylenes with a 1,1′‐Ferrocenylene Backbone and Bis(2,4,6‐triisopropylphenyl)boryl N‐Substituents

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Ferrocene‐based N‐heterocyclic tetrylenes [Fe{(η5‐C5H4)NBTrip2}2E](E = GePb; Trip = C6H2‐2,4,6‐iPr3)exhibit long EN and short BN bonds, in agreement with increased electrophilicity due to the ‐M effect of the N‐substituents, whose stericdemand prevents coordination of 4‐(dimethylamino)pyridine (DMAP) to theplumbylene PbII atom, but allows the ...

Dynamic Bayesian Network for Continuous Health Index Estimation and Condition Assessment of Power Transformers

open access: yesHigh Voltage, EarlyView.
ABSTRACT To address the limitations of traditional transformer health index (HI), such as high dependence on data integrity and inability to assist in diagnosing latent faults, this study proposes an HI prediction method based on dynamic Bayesian network (DBN).

Radio Interference Prediction Method for EHV AC Transmission Lines at High Altitudes Based on Long‐Term Observations

open access: yesHigh Voltage, EarlyView.
ABSTRACT Radio interference (RI) is a critical factor in the design of extra‐high voltage (EHV) transmission lines at high altitudes. To address the insufficient field data of RI on high‐altitude transmission lines, the lack of adequate validation for existing RI prediction methods, and the difficulty in assessing RI levels under various meteorological

Signal‐to‐noise and spatial resolution in in‐line imaging. 3. Optimization using a simple model

open access: yesJournal of Synchrotron Radiation, EarlyView.
Geometrical magnification and X‐ray energy are optimized with respect to spatial resolution, contrast, noise, radiation dose and other image quality characteristics. The optimization is performed using a simple theoretical model of a homogeneous edge feature embedded in a bulk uniform sample, and the resulting generic analytical expressions for image ...
