A QCIF 145dB imager for focal plane processor chips using a tone mapping technique in standard 0.35μm CMOS technology [PDF]
, 2011 This paper presents a QCIF HDR imager where visual information is simultaneously captured and adaptively compressed by means of an in-pixel tone mapping scheme [1]. The tone mapping curve (TMC) is calculated from a nonlinear histogram of the previous

Content-Aware Reverse Tone Mapping [PDF]
Proceedings of the 2016 International Conference on Artificial Intelligence: Technologies and Applications, 2016 We present an image analysis approach for reverse tone mapping of high dynamic range (HDR) content. The goal is to expand the dynamic range of existing low dynamic range content, to be properly shown on modern HDR displays. Most of the existing reverse tone mapping operators fail to offer a good solution in cases where the input images contain large ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand
FEBS Letters, EarlyView.Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

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 ...

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.

Deep Reformulated Laplacian Tone Mapping
, 2021 Wide dynamic range (WDR) images contain more scene details and contrast when compared to common images. However, it requires tone mapping to process the pixel values in order to display properly. The details of WDR images can diminish during the tone mapping process.

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
