Trade-offs among cost, integration, and segregation in the human connectome [PDF]

open access: yesNetwork Neuroscience, 2023
The human brain structural network is thought to be shaped by the optimal trade-off between cost and efficiency. However, most studies on this problem have focused on only the trade-off between cost and global efficiency (i.e., integration) and have ...

Ore-forming mechanism of quartz-vein-type W-Sn deposits of the Xitian district in SE China: Implications from the trace element analysis of wolframite and investigation of fluid inclusions

open access: yesOre Geology Reviews, 2017
Abstract The Xitian W–Sn district is located in eastern Hunan Province of SE China and comprises the Heshuxia, Goudalan, and Longshang W–Sn deposits. Our study on the occurrence, mineral assemblage, and geochemistry of the orebodies shows that quartz-vein orebodies are dominant mode of mineralization and can be divided into three stages: stage I ...

Double-vein (ore-bearing vs. ore-free) structures in the Xitian ore field, South China: Implications for fluid evolution and mineral exploration

open access: yesOre Geology Reviews, 2019
Abstract Two types of spatially and temporally associated hydrothermal veins, ore-bearing and ore-free, occur as double vein structures in the Xitian ore field, South China. Here, we investigated the genetic relationship, material provenance, fluid properties, and prospecting significance of the co-developed veins in the granite-related, fault ...

Lipid goal attainment in post-acute coronary syndrome patients in China: Results from the 6-month real-world dyslipidemia international study II. [PDF]

open access: yesClin Cardiol, 2021
Abstract Background Dyslipidemia International Study II (DYSIS II)‐China was conducted to determine the low‐density lipoprotein cholesterol (LDL‐C) goal (<1.8 mmol/L) attainment rate in patients with post‐acute coronary syndrome (ACS). Hypothesis Compliance with treatment guideline recommendations improves the LDL‐C goal attainment rate in post‐ACS ...

Direct Observation of Hybridization Between Co 3d and S 2p Electronic Orbits: Moderating Sulfur Covalency to Pre-Activate Sulfur-Redox in Lithium-Sulfur Batteries. [PDF]

open access: yesAdv Sci (Weinh)
Advanced inverse photoemission spectroscopy/ultraviolet photoelectron spectroscopy (IPES/UPS) experimentally probes the hybridization of Co 3d and S 2p after Li (from LiPSs) insertion in NC matrix, which gives rise to an enhanced sulfur covalency can pre‐activate the sulfur‐redox and thus improves lithium–sulfur battery performances.
