Characterizing the Temporal Variation of Airborne Particulate Matter in an Urban Area Using Variograms

Air
This study aims to determine the optimal frequency for monitoring airborne pollutants in densely populated urban areas to effectively capture their temporal variations. While environmental organizations worldwide typically update air quality data hourly,

Soliton Solutions to the Einstein Equations in Five Dimensions

, 2006
We present a new class of solutions in odd dimensions to Einstein's equations containing either a positive or negative cosmological constant. These solutions resemble the even-dimensional Eguchi-Hanson--(anti)-de Sitter ((A)dS) metrics, with the added ...

Eguchi-Hanson like space-times in F(R) gravity [PDF]

, 2012
We consider a model of F (R) gravity in which exponential and power corrections to Einsteingravity are included. We show that this model has 4-dimensional Eguchi-Hanson type instanton solutions in Euclidean space.

Phospholipid composition of reconstituted high density lipoproteins influences their ability to inhibit endothelial cell adhesion molecule expression

Journal of Lipid Research, 2000
The ability of different phosphatidylcholine (PC) species to inhibit cytokine-induced expression of vascular cell adhesion molecule 1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs) was investigated. PC species containing palmitoylin the sn-1

The China Shock: Learning from Labor Market Adjustment to Large Changes in Trade

Social Science Research Network, 2016
China’s emergence as a great economic power has induced an epochal shift in patterns of world trade. Simultaneously, it has toppled much of the received empirical wisdom about how labor markets adjust to trade shocks.

Methanotrophic bacteria.

Microbiological reviews, 1996
Methane-utilizing bacteria (methanotrophs) are a diverse group of gram-negative bacteria that are related to other members of the Proteobacteria. These bacteria are classified into three groups based on the pathways used for assimilation of formaldehyde,

Analyzing individual rent price ratios in eastern German agricultural land markets: A GAMLSS approach

Agribusiness, EarlyView.
Abstract This study explores the rent price ratio in agricultural land markets, crucial for evaluating market efficiency, policy needs, and farmer decision‐making. Traditionally, the analyses faced challenges due to the absence of concurrent sale and rent data for the same land, potentially leading to biased results.
