The Simple prEservatioN of Single cElls method for cryopreservation enables the generation of single-cell immune profiles from whole blood

Frontiers in Immunology, 2023
IntroductionCurrent multistep methods utilized for preparing and cryopreserving single-cell suspensions from blood samples for single-cell RNA sequencing (scRNA-seq) are time-consuming, requiring trained personnel and special equipment, so limiting their

Characteristics of plasma boundaries with large density gradients and their effects on Kelvin–Helmholtz instability

Frontiers in Astronomy and Space Sciences
Boundaries between space plasmas occur in numerous contexts and scales, from astrophysical jets to planetary magnetospheres. Mass and momentum transport across boundaries poses a fundamental problem in magnetospheric physics. Kelvin–Helmholtz instability

The effect of a density difference on shear-layer instability [PDF]

, 1972
Measurements of mass flow rate and mean density have been made in separated laminar boundary layers with large transverse density gradients. Two-dimensional shear layers were formed by exhausting a half-jet of one gas into a reservoir of another gas with

Design and fabrication of a microfluidic device for separation of lymphocytes for use as part of a radiation biodosimeter

Engineering and Applied Science Research, 2022
A radiation biodosimeter is a measure of biological response to radiation that can help determine the exact dose received by using biological markers or radiation-damaged chromosomes using a blood sample as a surrogate tissue. Today, many researchers are

Burgers Turbulence with Large-scale Forcing

, 1998
Burgers turbulence supported by white-in-time random forcing at low wavenumbers is studied analytically and by computer simulation. It is concluded that the probability density Q of velocity gradient displays four asymptotic regimes at very large ...

A macroscopic crowd motion model of gradient flow type [PDF]

, 2010
A simple model to handle the flow of people in emergency evacuation situations is considered: at every point x, the velocity U(x) that individuals at x would like to realize is given.

Tangling clustering of inertial particles in stably stratified turbulence

, 2010
We have predicted theoretically and detected in laboratory experiments a new type of particle clustering (tangling clustering of inertial particles) in a stably stratified turbulence with imposed mean vertical temperature gradient.

Can Microfluidics Improve Sperm Quality? A Prospective Functional Study

Biomedicines
The same sperm selection techniques in assisted reproduction clinics have remained largely unchanged despite their weaknesses. Recently, microfluidic devices have emerged as a novel methodology that facilitates the sperm selection process with promising ...

Density-Functional-Based Determination of the CH3-CH4 Hydrogen Exchange Reaction Barrier

, 1994
Due to the overbinding that is inherent in existing {\em local} approximations to the density-functional formalism, certain reaction energies have not been accessible.

Combining Step Gradients and Linear Gradients in Density [PDF]

Analytical Chemistry, 2015
Combining aqueous multiphase systems (AMPS) and magnetic levitation (MagLev) provides a method to produce hybrid gradients in apparent density. AMPS—solutions of different polymers, salts, or surfactants that spontaneously separate into immiscible but predominantly aqueous phases—offer thermodynamically stable steps in density that can be tuned by the ...
