Light-field imaging based on tilt-aberration
, 2023 Disclosed is a method for obtaining a transverse phase gradient of a wave field from at least a first and a second wavefield intensity map comprising the steps of; capturing at a first incoherent tilt aberration said first wave field intensity map of a target at a first degree of incoherent tilt aberration, using a filter positioned between a source of

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

IEEE AccessThe most popular technique for converting two-class images into binary images is thresholding. However, thresholding methods tend to perform poorly when dealing with images affected by uneven lighting. To address this issue, local thresholding techniques

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Mechanisms of parasite‐mediated disruption of brain vessels
FEBS Letters, EarlyView.Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

A NON-LINEAR TECHNIQUE FOR THE ENHANCEMENT OF EXTREMELY NON-UNIFORM LIGHTING IMAGES
Havacılık ve Uzay Teknolojileri Dergisi, 2007 At night scenes and under nonuniform lighting conditions, either the low intensity areas or the high intensity areas cannot be clearly seen. Various image processing techniques have been developed to recover the meaningful

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Image Enhancement by Frequency Analysis
MATEC Web of Conferences, 2018 Because of lighting or the quality of CMOS/CCD, poor images are often gained, which greatly affect subjective observation. Image enhancement can improve the contrast of poor image.
