Role of pressure anisotropy on relativistic compact stars

, 2018
We investigate a compact spherically symmetric relativistic body with anisotropic particle pressure profiles. The distribution possesses characteristics relevant to modeling compact stars within the framework of general relativity.

Porous dust grains in debris disks [PDF]

, 2013
When modeling the density and grain size distribution in debris disks, the minimum particle size is often significantly larger than the corresponding blowout size.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Leading-Edge Thin-Layer MOSFET Potential Modeling Toward Short-Channel Effect Suppression and Device Optimization

IEEE Journal of the Electron Devices Society, 2019
A novel compact model has been developed, which considers the origin of the short-channel effect (SCE) on the basis of the potential distribution along the channel. Thus an enlargement of the insight into SCE suppression in advanced thin-layer MOSFETs is

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

3-nm CFET Process Design Kit for Advancing MOL-Aware Modeling for Precise Circuit Performance Analysis

IEEE Access
Complementary field-effect transistors (CFETs) improve integration density through vertical stacking, but dense middle-of-line (MOL) routing introduces significant parasitics that affect circuit performance.

Influence of $f(R)$ Models on the Existence of Anisotropic Self-Gravitating Systems

, 2017
This paper aims to explore some realistic configurations of anisotropic spherical structures in the background of metric $f(R)$ gravity, where $R$ is the Ricci scalar. The solutions obtained by Krori and Barua are used to examine the nature of particular

The magnetic nature of disk accretion onto black holes [PDF]

, 2006
Although disk accretion onto compact objects - white dwarfs, neutron stars, and black holes - is central to much of high energy astrophysics, the mechanisms which enable this process have remained observationally elusive.

RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

The Compact Model Synthesis for the RADFET Device

Technologies
This article proposes a compact model for the radiation-sensitive field-effect transistor (RADFET). The model represents the basic I–V characteristics of the MOSFET device and includes the effects of threshold voltage shift as a function of absorbed dose
