Adaptive Differential Event Detection for Space-Based Infrared Aerial Targets

open access: yesRemote Sensing
Space resources are of economic and strategic value. Infrared (IR) remote sensing, unaffected by geography and weather, is widely used in weather forecasting and defense.

Configurable circular-polarization-dependent optoelectronic silent state for ultrahigh light ellipticity discrimination

open access: yesLight: Science & Applications, 2023
Filterless light-ellipticity-sensitive optoelectronic response generally has low discrimination, thus severely hindering the development of monolithic polarization detectors.

Effect of terahertz irradiation on DNA damage repair in living cells

open access: yesFEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Evaluation of time-series registration methods in dynamic area telethermometry for breast cancer detection [PDF]

open access: yes, 2013
Automated motion reduction in 3D dynamic infrared imaging is on demand in many applications. Few methods for registering time-series dynamic infrared frames have been proposed.

Analytical and simulation performance modelling of indoor infrared wireless data communications protocols [PDF]

open access: yes
The Infrared (IR) optical medium provides an alternative to radio frequencies (RF) for low cost, low power and short-range indoor wireless data communications. Low-cost optoelectronic components with an unregulated IR spectrum provide the potential for

TRPML1 agonist ML‐SA5 attenuates pulmonary fibroblast activation by suppressing mTOR and restoring autophagic flux

open access: yesFEBS Open Bio, EarlyView.
TGF‐β1 stimulation downregulates lysosomal channel TRPML1 in pulmonary fibroblasts. The TRPML1 agonist ML‐SA5 suppressed fibroblast‐to‐myofibroblast activation and collagen production. Mechanistically, ML‐SA5 inhibited mTOR phosphorylation, restored autophagic flux, and its effects were enhanced by rapamycin (mTOR inhibitor) and reversed by MHY1485 ...

The Use of Infrared Technology To Detect Heat Loss

open access: yes, 1979
Infrared refers to electro magnetic energy with a wave length longer than those of visible light. Researchers developed methods to quantify, focus and form real-time images to infrared energy. This spawned the development of infrared Thenrography.

Long‐Term Efficacy of Immunotherapy in Autoimmune Autonomic Ganglionopathy—A 10‐Year Follow Up Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Autoimmune autonomic ganglionopathy (AAG) is a rare but potentially treatable cause of severe autonomic failure. Evidence guiding long‐term immunotherapy, treatment sequencing, and residual autonomic impairment is limited. We evaluated long‐term treatment response, residual autonomic dysfunction, and relapse patterns in patients with

Silicon photonic modulators for the mid-infrared

open access: yes, 2013
Mid-infrared group-IV material photonics is an emerging field, which aims to migrate techniques used for near-infrared silicon photonics to longer wavelengths, and to address applications in areas such as environmental and bio-chemical sensing, homeland ...
