Climbing the Density Functional Ladder: Non-Empirical Meta-Generalized Gradient Approximation Designed for Molecules and Solids

open access: yesPhysical Review Letters, 2003
The electron density, its gradient, and the Kohn-Sham orbital kinetic energy density are the local ingredients of a meta-generalized gradient approximation (meta-GGA).

Extracellular Vesicles (EVs) Are Copurified with Feline Calicivirus, yet EV-Enriched Fractions Remain Infectious

open access: yesMicrobiology Spectrum, 2022
Feline calicivirus (FCV) is a major cause of upper respiratory disease in cats and is often used as a model for human norovirus, making it of great veterinary and human medical importance.

Optimization of The Cell Aggregates Method for Isolation and Purification of Human Granulosa Cells from Follicular Fluid [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2020
Background Aspirated ovarian follicular fluids (FF) contain luteal granulosa cells (LGCs) and other contaminating cell types. Several strategies, such as the antibody binding methods, the flask method, the cell strainer and positive selection of ...

Using spatial distance sampling models to optimize survey effort and address violations of the design assumption

open access: yesEcological Solutions and Evidence, 2021
Conventional distance sampling approaches rely on the design assumption (i.e. uniform distribution of individuals in relation to transects) to ensure unbiased inference to the population of interest.

Does choosing microfluidics for sperm sorting offer an advantage to improve clinical pregnancies in donor egg recipients?

open access: yesJournal of Human Reproductive Sciences, 2022
Background: Microfluidics (MF), an advanced sperm sorting technology results in the extraction of spermatozoa with higher DNA integrity and lower DNA damage compared to existing conventional sperm sorting methods. Aims: The aim of the present study is to

Continuous Percoll Gradient Centrifugation of Erythrocytes—Explanation of Cellular Bands and Compromised Age Separation

open access: yesCells, 2022
(1) Background: When red blood cells are centrifuged in a continuous Percoll-based density gradient, they form discrete bands. While this is a popular approach for red blood cell age separation, the mechanisms involved in banding were unknown.

Smooth-Particle Phase Stability with density and density-gradient potentials [PDF]

open access: yes, 2005
Stable fluid and solid particle phases are essential to the simulation of continuum fluids and solids using Smooth Particle Applied Mechanics. We show that density-dependent potentials, such as Phi=(1/2)Sum (rho-rho_0)^2, along with their corresponding ...

Low-Density Granulocyte Contamination From Peripheral Blood Mononuclear Cells of Patients With Sepsis and How to Remove It – A Technical Report

open access: yesFrontiers in Immunology, 2021
Elucidating the mechanisms contributing to the dysregulated host response to infection as part of the syndrome is a current challenge in sepsis research. Peripheral blood mononuclear cells are widely used in immunological studies.

ASSESSMENT OF GAS-HYDROTHERMAL ACTIVITY OF THE BAIKAL RIFT IN THE LAKE AREA FROM NUMERICAL EXPERIMENT DATA

open access: yesГеодинамика и тектонофизика, 2015
The Baikal rift is characterized by high heat flow, seismic activity and large thickness of sediments through which gas and hydrothermal water are intensely released into the lake water.
