Previous work revealed that bloodsucking bugs can discriminate between oscillating changes in infrared (IR) radiation and air temperature (T) using two types of warm cells located in peg-in-pit sensilla and tapered hairs (Zopf LM, Lazzari CR, Tichy H. J Neurophysiol 111: 1341-1349, 2014). These two stimuli are encoded and discriminated by the response quotient of the two warm cell types. IR rad...

Radiation accidents frequently involve acute high dose partial body irradiation leading to victims with radiation sickness and cutaneous radiation syndrome that implements radiation-induced cell death. Cells that are not lethally hit seek to repair ionizing radiation (IR) induced damage, albeit at the expense of an increased risk of mutation and tumor formation due to misrepair of IR-induced DN...

Results are presented for a dual-band detector that simultaneously detects UV radiation in the 250-360 nm and IR radiation in the 5-14 microm regions with near zero spectral cross talk. In this detector having separate UV- and IR-active regions with three contacts (one common contact for both regions) allows the separation of the UV and IR generated photocurrent components, identifying the rela...

Abstract The damaging effects of illumination on artwork are well known. Art conservation requires protection from both vandalism and radiation damage. Glass is an appropriate material for these requirements but it partially transmits UV and IR radiation. An optical coating on glass that eliminates UV and IR radiation coming from natural or artificial illumination, is proposed. This coated glas...

OBJECTIVE Infrared (IR) irradiation specialized with wavelengths and contact cooling increases the amount of water in the dermis to protect the subcutaneous tissues against IR damage; thus, it is applied to smooth forehead wrinkles. However, this treatment consistently induces brow ptosis. Therefore, we investigated whether IR irradiation induces muscle thinning. METHODS Rat central back tiss...

Absorption spectra of infra-red (IR) radiation of the disperse water medium absorbing the most important greenhouse gases: 2 CO , O N2 , 4 CH , 2 2H C , 6 2H C have been calculated by the molecular dynamics method. Loss of the absorbing ability at the formation of clusters due to a reduction of the number of centers interacting with IR radiation, results in an anti-greenhouse effect. Absorption...

This work presents measured results demonstrating an uncooled infrared (IR) detector based on gallium nitride (GaN) micromechanical resonators. GaN-based photonic detectors are typically designed to operate in the ultraviolet (UV) regime as the absorption spectrum of wide-band gap GaN peaks at a wavelength of ~360 nm. In contrast, the transduction mechanism of the device presented in this work ...

We used a spectral radiative transfer model to compute the direct radiative effect (DRE) of natural plus anthropogenic aerosols in the solar near-infrared (IR), between 0.85–10μm, namely, their effect on the outgoing nearIR radiation at the top of atmosphere (TOA, 1FTOA), on the atmospheric absorption of near-IR radiation (1Fatmab) and on the surface downward and absorbed near-IR radiation (1Fs...

Global transcriptomic and proteomic profiling platforms have yielded important insights into the complex response to ionizing radiation (IR). Nonetheless, little is known about the ways in which small cellular metabolite concentrations change in response to IR. Here, a metabolomics approach using ultraperformance liquid chromatography coupled with electrospray time-of-flight mass spectrometry w...

The dose limiting toxicities of Ionizing Radiation (IR) in radiosensitive normal tissues, such as bone marrow, intestine, and skin, precludes the delivery of curative or effective palliative doses of radiation in many cases. Despite of the intense research effort in the past to find new effective and well-tolerated radioprotectors, only one drug has been approved by FDA for this indication. One...
