Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Aspect dependent optical continuum emission in radio quasars [PDF]
, 1996 We have defined a new, complete, low-frequency selected sample of southern radio quasars, the Molonglo Quasar Sample, with the aim of studying the aspect dependence of the radio and optical emission. As a test for enhancement of the optical continuum, we

Radio continuum emission in ring galaxies
The Astronomical Journal, 1980 Radio emission was found in two (Arp 118 and Arp 148) of 27 ring-type galaxies searched with the NRAO interferometer to a detection limit of about 10 mJy at 11.1 cm. These two were also observed at 6 cm with the higher sensitivity and resolution of the VLA.

Effect of terahertz irradiation on DNA damage repair in living cells
FEBS 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.

SEARCH FOR A COMPACT SCINTILLATING COMPONENT IN SNR 3С58 AT DECAMETER WAVELENGTHS
Radio Physics and Radio Astronomy, 2014 The upper limit for the flux of a compact source of continuum radio emission in SNR 3C58, (2.7 ± 0.9) Jy, was obtained by the highest sensitive observations of interplanetary scintillations at decameter wavelengths.

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.

Detections of Compact Radio Continuum toward Methanol Maser Rings Using the VLA
The Astrophysical JournalHigh-mass protostars are deeply embedded in dust inside their natal cores and are not easily detectable. However, maser emission at centimeter wavelengths, owing to its high brightness, enables us to study gas kinematics in protostars’ circumstellar ...

Radio Continuum Emission from FS CMa Stars
, 2011 The FS CMa stars exhibit bright optical emission-line spectra and strong IR excesses. Very little is known of their radio characteristics. We analyzed archive Very Large Array data to search for radio continuum emission in a sample of them. There are good quality data for seven of the $\sim$40 known FS CMa stars.

Advanced Engineering Materials, EarlyView.Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...
