Thermal niche breadth shapes regional elevational range sizes of tropical‐like mountain stream insects: evidence for Janzen's tropical mountain passes hypothesis

open access: yesEcography, EarlyView.
The core of Janzen's tropical mountain passes hypothesis is that relatively stable annual temperature variation limits species' thermal tolerances breadth, which, in combination with steep elevational temperature gradients, constrains the elevational distributions of these species. In addition to thermal niche breadth, elevational ranges were shaped by

Synthesis of Naphthoquinones by Pd‐Catalyzed Heck–Matsuda Arylation of Lapachol

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Direct Heck–Matsuda arylation of lapachol enables the efficient synthesis of diverse naphthoquinones under homogeneous and heterogeneous palladium catalysis. The methodology features broad substrate scope, gram‐scale applicability, and provides a practical platform for quinone diversification.

Influence of Outer Protective Sleeve on the Flow Capacity of Concentric Screen

open access: yesShiyou jixie
The outer protective sleeve is an important component of the mechanical screen, and its influence on the flow capacity of the screen cannot be ignored. Taking the concentric screen as an example, the influence of the outer protective sleeve on the flow ...

Effect of the Surface Roughness on the Shear Strength of Granular Materials in Ring Shear Tests

open access: yesApplied Sciences, 2019
Surface roughness plays an important role in estimating the shear strength of granular materials. A series of ring shear tests with different surface roughnesses (i.e., smooth and rough surfaces) were performed.

Oligogenic inheritance in epilepsy: A systematic exome‐wide analysis

open access: yesEpilepsia, EarlyView.
Abstract Objective Genetic factors contribute to the majority of epilepsies, but the exact genetic cause remains unknown in most patients. Incomplete penetrance and variable expressivity are frequent, and recent studies showed a burden of deleterious variants in epilepsy genes, suggesting a role for oligogenic inheritance.
