Meta-Analysis of Transfer Learning for Segmentation of Brain Lesions [PDF]
arXiv, 2023 A major challenge in stroke research and stroke recovery predictions is the determination of a stroke lesion's extent and its impact on relevant brain systems. Manual segmentation of stroke lesions from 3D magnetic resonance (MR) imaging volumes, the current gold standard, is not only very time-consuming, but its accuracy highly depends on the operator'

Chronic brucellosis with sacroiliitis: A case report
Clinical Case Reports, Volume 12, Issue 11, November 2024.Key Clinical Message Brucellosis, especially with osteoarticular involvement, is uncommon and difficult to diagnose, but it should be considered in a case presenting with prolonged fever, joint pain, and back pain. The diagnosis requires a combination of history, serological examinations, and radiographic studies.

Effects of bacterial density on growth rate and characteristics of microbial-induced CaCO3 precipitates: a particle-scale experimental study [PDF]
arXiv, 2020 Microbial-Induced Carbonate Precipitation (MICP) has been explored for more than a decade as a promising soil improvement technique. However, it is still challenging to predict and control the growth rate and characteristics of CaCO3 precipitates, which directly affect the engineering performance of MICP-treated soils.

Bacterial biofilms use chiral branches to escape crowded environments by tracking oxygen gradient [PDF]
arXiv, 2022 Bacterial biofilms collectively develop distinct and ordered structures, including fibers, bundles, and branches. Often, it is unclear how these structural motifs convey specific advantages to bacterial strains under challenging conditions. In oxygen-limited environments, dense bacterial aggregates generally deplete oxygen, which leads to arrest of ...

Recurrent fungal endocarditis of the aortic valve: A challenging clinical scenario
Clinical Case Reports, Volume 12, Issue 10, October 2024.Key Clinical Message Fungal endocarditis is a rare but potentially fatal infection with significant diagnostic and management challenges. Antifungal therapy and surgical debridement are the preferred treatments in these cases. Antimicrobial therapy with multiple antifungal agents may be required in high‐risk patients presenting with prolonged fever ...

Atypical post‐infectious glomerulonephritis with c‐ANCA positivity followed by endocarditis
Nephrology, Volume 29, Issue 9, Page 607-611, September 2024.Abstract Post‐infectious glomerulonephritis (PIGN), an uncommon variety of glomerulonephritis (GN), is characterized by emergence of nephritic syndrome within a few weeks following an infectious event. PIGN typically presents as a mild condition and tends to resolve by the time of diagnosis for GN.

Onset of Shear Waves In A Bacterial Bath: A Novel Effect [PDF]
arXiv, 2003 Recent experiments on particle diffusion in bacterial baths indicate the formation of correlated structures in the form of bacterial swirls. Here we predict that such a structural ordering would give rise to the new effect of propagating shear waves in a bacterial bath at length scales of the order of a swirl, which corresponds to time scales of the ...
