A Phase Field Model for Continuous Clustering on Vector Fields [PDF]

, 2001
A new method for the simplification of flow fields is presented. It is based on continuous clustering. A well-known physical clustering model, the Cahn Hilliard model, which describes phase separation, is modified to reflect the properties of the data to

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

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.

Transcranial Magnetic Stimulation to the Occipital Place Area Biases Gaze During Scene Viewing

Frontiers in Human Neuroscience, 2018
We can understand viewed scenes and extract task-relevant information within a few hundred milliseconds. This process is generally supported by three cortical regions that show selectivity for scene images: parahippocampal place area (PPA), medial place ...

Human frontal eye fields and spatial priming of pop-out

, 2007
"Priming of pop-out" is a form of implicit memory that facilitates detection of a recently inspected search target. Repeated presentation of a target's features or its spatial position improves detection speed (feature/spatial priming).

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Review on Diagnostic Modalities in Idiopathic Intracranial Hypertension

Delhi Journal of Ophthalmology, 2020
IIH is a well-known but under investigated condition with an unclear etio-pathogenesis. An increase in the incidence of IIH has also been noted in the recent years, which necessitates the need for diagnostic tools to diagnose and monitor the progression ...

Visual acuity after trabeculectomy [PDF]

Vojnosanitetski Pregled, 2005
Background/Aim. In this study we compared the two groups of glaucoma patients who had underwent trabeculectomy, with or without intraoperative application of antimetabolite 5-Fluorouracile (5 FU). Methods. We followed up 50 glaucoma patients (group I) in

A CORF computational model of a simple cell that relies on LGN input outperforms the Gabor function model [PDF]

, 2012
Simple cells in primary visual cortex are believed to extract local contour information from a visual scene. The 2D Gabor function (GF) model has gained particular popularity as a computational model of a simple cell.
