The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Numerical Simulation of a Turbulent Flow in a Channel with Surface Mounted Cubes [PDF]

, 1998
In this paper we report on a fourth-order, spectro-consistent simulation of a complex turbulent flow. A spatial discretization of a convection-diffusion equation is termed spectro-consistent if the spectral properties of the convective and diffusive ...

Filtered density functions from direct numerical simulation of a reactive jet in cross-flow

, 2010
Direct numerical simulation (DNS) with multi-step hydrogen-air chemical kinetics is used to investigate the nearfield of a flame stabilized above a reactive jet in cross-flow (JICF). JICF configurations are typically used where rapid mixing is desirable;

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

The Bottleneck in the Scalar Dissipation Rate Spectra: Dependence on the Schmidt Number

Fluids
The mean dissipation rate of turbulent energy reaches a constant value at high Taylor–Reynolds numbers (Rλ). This value is associated with the well-scaling dissipation spectrum in Kolmogorov units, where the maximum corresponds to the bottleneck peak ...
