Photochemistry and Photobiology, EarlyView.Far‐UVC (200–235 nm) has emerged as a safe and effective indoor disinfection tool, but effects on skin immunomodulation remain unclear. This study demonstrates that 222 nm far‐UVC converts trans‐urocanic acid (UCA) to its biologically active cis isomer at levels comparable with solar radiation. In keratinocytes, far‐UVC alone caused modest increases in

Photochemistry of CryB from Rhodobacter sphaeroides
Photochemistry and Photobiology, EarlyView.Elucidation of the photochemistry of CryB from Rhodobacter sphaeroides was achieved from the nanosecond to second timescale. A fast (<5 ns) deprotonation of the terminal electron donor Trp338 and the involvement of Tyr337 in photoreduction have been revealed.

Plant Biology, EarlyView.Pre‐treatment of grapevine plants with oregano essential oil vapour alleviates downy mildew susceptibility by accumulation of monoterpenol glycosides. Abstract Grapevine downy mildew, caused by the oomycete Plasmopara viticola, is a destructive disease that causes major economic losses as most elite grapevine cultivars are susceptible to this pathogen.

Plant Biology, EarlyView.Common bean genotypes differ in their iron acquisition through distinct Strategy I responses and root exudation patterns. Abstract Iron (Fe) deficiency in food crops, particularly on calcareous soils, limits productivity and human nutrition. This study investigated two common bean (Phaseolus vulgaris) genotypes, Guaymí (high Fe‐accumulating, HI) and ...

The Journal of Physiology, EarlyView.Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...

Voltage‐gated potassium channels mediate thyroid hormone control of skeletal muscle excitability
The Journal of Physiology, EarlyView.Abstract figure legend Thyroid hormone (TH)‐dependent remodelling of potassium (K+) channel networks regulates skeletal muscle (SkM) excitability. Triiodothyronine (T3), locally generated from thyroxine (T4) by type 2 deiodinase (D2), binds thyroid hormone receptors (TRα/β) and modulates transcription via thyroid response elements (TREs).

Energy-Efficient Design in RF Energy Harvesting Relay Networks [PDF]
2015 IEEE Global Communications Conference (GLOBECOM), 2014 In this paper, the energy-efficient design of wireless relay networks with radio frequency (RF) energy harvesting capability is studied. A decode-and-forward relay is used to forward information and harvest energy simultaneously from the same signal with a power splitting architecture.

This paper presents the results of a project in RF Energy Harvesting for scavenging energy from the ubiquitous radio-frequency (RF) electromagnetic waves. Such a device can be very useful to charge mobile phone in jungles and in remote areas or where the electric utility is not available or not reliable.

RF Energy Harvesting in Wireless Networks with HARQ [PDF]
2016 IEEE Globecom Workshops (GC Wkshps), 2016 In this paper, we consider a class of wireless powered communication networks using data link layer hybrid automatic repeat request (HARQ) protocol to ensure reliable communications. In particular, we analyze the trade-off between accumulating mutual information and accumulating RF energy at the receiver of a point-to-point link using HARQ with ...

Harvesting or scavenging the RF(Radio Frequency) energy, better known by its engineering name — “RF energy Scavenging”, is one of the emerging fields, with very good research opportunities. It is a technique, by which, we utilize the RF energy present in the external atmosphere, by scavenging, and convert it into an useful electrical output for driving
