Hyperfine interactions at 181Ta solute in ferromagnetic Hf-Ni alloys with low concentration of Hf atoms [PDF]

open access: yes, 2008
We have measured hyperfine interactions of 181Ta probe in the polycrystalline 0.2at.%Hf-Ni, 2at.%Hf-Ni and 5at.%Hf-Ni alloys, by the time differential perturbed angular correlation (TDPAC) method at room temperature (RT).

Brain Pathology in Myotonic Dystrophy: When Tauopathy Meets Spliceopathy and RNAopathy

open access: yesFrontiers in Molecular Neuroscience, 2014
Myotonic dystrophy (DM) of type 1 and 2 (DM1 and DM2) are inherited autosomal dominant diseases caused by dynamic and unstable expanded microsatellite sequences (CTG and CCTG, respectively) in the non-coding regions of the genes DMPK and ZNF9 ...

Hydrological Changes Caused by Integrated Warming, Wetting, and Greening in Permafrost Regions of the Qinghai‐Tibetan Plateau

open access: yesWater Resources Research, Volume 61, Issue 4, April 2025.
Abstract The Qinghai‐Tibetan Plateau (QTP) has undergone significant warming, wetting, and greening (WWG) over decades, alongside substantial alterations in hydrological regimes. These changes present great challenges for safeguarding water resources and ecosystems downstream.

Visible‐Light‐Switchable Molecular Glues for Reversible Control of Protein Function

open access: yesChemistry – A European Journal, Volume 31, Issue 15, March 12, 2025.
This work presents a modular chemo‐optogenetic system using azobenzene‐based photoswitchable molecular glues (sMGs) to reversibly control protein dimerization/proximity. This system enables reversible control of protein function using orthogonal green/blue and red/blue light Abstract Chemically induced dimerization/proximity (CID/CIP) systems ...

Correlation between differential drought tolerability of two contrasting drought-responsive chickpea cultivars and differential expression of a subset of CaNAC genes under normal and dehydration conditions

open access: yesFrontiers in Plant Science, 2015
Drought causes detrimental effect to growth and productivity of many plants, including crops. NAC transcription factors (TFs) have been reported to play important role in drought tolerance.

A Systematic Review of U‐Net Optimizations: Advancing Tumour Segmentation in Medical Imaging

open access: yesIET Image Processing, Volume 19, Issue 1, January/December 2025.
Since its introduction in 2015, U‐Net has become a foundational model for medical image segmentation, yet challenges remain in tumour segmentation due to heterogeneity and boundary ambiguity. This PRISMA‐based systematic review examines recent strategies aimed at enhancing U‐Net's performance for tumour segmentation in CT and MRI, focusing on backbone,

The influence of electrode material on gas-filled surge arresters response time in gamma and X radiation field [PDF]

open access: yes, 2007
Cilj ovog rada je da se ispita uticaj materijala elektroda na impulsnu karakteristiku modela gasnog odvodnika prenapona u polju gama i X zračenja. Pokazano je da oba tipa zračenja dovode do povećanja brzine odziva odvodnika.
