Retinal biomarkers of Cerebral Small Vessel Disease: A systematic review

Plos.org 

by Elena Biffi, Zachary Turple, Jessica Chung, Alessandro Biffi

Introduction

Cerebral Small Vessel Disease (CSVD), a progressive degenerative disorder of small caliber cerebral vessels, represents a major contributor to stroke and vascular dementia incidence worldwide. We sought to conduct a systematic review of the role of retinal biomarkers in diagnosis and characterization of CSVD.

Methods

We conducted a systematic review of MEDLINE, PubMed, Scopus, the Cochrane Library Database, and Web of Science. Читать дальше...

Socio-economic drivers of irrigated paddy land abandonment and agro-ecosystem degradation: Evidence from Japanese agricultural census data

Plos.org 

by Kota Mameno, Takahiro Kubo

The abandonment of irrigated paddy land has increased in Japan, which can cause a decline in food security and biodiversity. Despite the importance of individual decisions, most studies have only examined regional or community-based determinants of paddy land abandonment. This study aimed to uncover the socio-economic determinants affecting individual landowners’ decisions to abandon paddy land, using Japanese agricultural census data (2005, 2010, and 2015) composed...

Association between use of sodium-glucose cotransporter 2 inhibitors, glucagon-like peptide 1 agonists, and dipeptidyl peptidase 4 inhibitors with kidney outcomes in patients with type 2 diabetes: A systematic review and network meta-analysis

Plos.org 

by Shuo Yang, Wei He, Lu Zhao, Yaochuan Mi

Background

This study aimed to compare the efficacies of sodium-glucose cotransporter 2 (SGLT-2) inhibitors, glucagon-like peptide 1 (GLP-1) agonists, and dipeptidyl peptidase 4 (DPP-4) inhibitors on kidney outcomes in patients with type 2 diabetes using network meta-analysis.

Methods

PubMed, EMBASE, and CENTRAL were searched for studies published up to September 28, 2020. Randomized clinical trials enrolling participants with type 2 diabetes were included... Читать дальше...



Mechanical properties of charcoal and its representativeness of vegetation in northern China

Plos.org 

by Nan Sun, Xiabo Li, Fan Luo, Liang Xiao

The objective of this paper is to examine the representativeness of charcoal taxa at archeological sites in northern China. We carried out standardized laboratory compression tests on 168 samples representing 21 taxa charred at four different temperatures to characterize the mechanical properties of common taxa in temperate China. The results indicate that significant fragmentation differences occur between taxa. Ring-porous/semi-ring-porous taxa... Читать дальше...

DAO-CP: Data-Adaptive Online CP decomposition for tensor stream

Plos.org 

by Sangjun Son, Yong-chan Park, Minyong Cho, U. Kang

How can we accurately and efficiently decompose a tensor stream? Tensor decomposition is a crucial task in a wide range of applications and plays a significant role in latent feature extraction and estimation of unobserved entries of data. The problem of efficiently decomposing tensor streams has been of great interest because many real-world data dynamically change over time. However, existing methods for dynamic tensor decomposition sacrifice the accuracy too much... Читать дальше...

Improved heat coefficients for joint-space metabolic energy expenditure model during level, uphill, and downhill walking

Plos.org 

by Jazmin Cruz, James Yang

A previously developed joint-space metabolic energy expenditure (MEE) model includes subject-specific parameters and was validated using level walking gait data. In this work, we determine how well this joint-space model performs during various walking grades (-8%, 0%, and 8%) at 0.8 m·s ⁻1 and 1.3 m·s ⁻1 using published gait data in the literature. In response to those results, we formulate an optimization problem and solve it through the particle swam method plus... Читать дальше...
