A Functionally Conserved Enhancer is Critical for PGC1A Expression and Thermogenesis in Brown Fat

Advanced Science, EarlyView.
An evolutionarily conserved enhancer controls PGC1A expression and thermogenic activation in brown adipose tissue. Integrative multi‐omics analyses identify two BAT‐specific enhancers, with PGC1A‐En1 functioning as the dominant regulatory element that maintains thermogenic capacity across species.

Isolation and Gain Enhancement Using Metamaterial Based Superstrate for MIMO Applications [PDF]

Radioengineering, 2019
In this paper, a metamaterial superstrate in¬spired multiple-input-multiple-output (MIMO) for gain and isolation enhanced antenna system is investigated for WLAN applications. The superstrate layer generates a resonant cavity effect which results in gain

Self‐Nitriding Nanostructured Transition Metal Nitrides in Architected‐Carbon Matrices: Unveiling Mechanisms and Advancing Performance in Lithium‐Sulfur Pouch Cells

Advanced Science, EarlyView.
Imidazolium PIL nanoparticles, as an N‐rich template and morphology director, enable a colloidal self‐nitriding route to TMNs (VN, Mo2N) within controlled solid/hollow carbon architectures. As sulfur hosts/additives, TMNs accelerate Li–S redox kinetics and support high‐loading cathodes.

Numerical Simulations of Thermohaline Convection: Implications for Extra-Mixing in Low-Mass RGB Stars

, 2010
Low-mass stars are known to experience extra-mixing in their radiative zones on the red-giant branch (RGB) above the bump luminosity. To determine if the salt-fingering transport of chemical composition driven by 3He burning is efficient enough to ...

ALKBH3 m1A Demethylase Deficiency Reduces Alzheimer's Amyloid‐β Pathology

Advanced Science, EarlyView.
This study identifies that ALKBH3‐driven m1A demethylation orchestrates Alzheimer's disease progression by disrupting mitochondrial and synaptic homeostasis. This epitranscriptomic mechanism suppresses PINK1‐mediated mitophagy via m1A erasure, leading to mitochondrial dysfunction, oxidative stress, elevated Aβ production, and impaired microglial ...
