A Late-time Radio Survey of Type Ia-CSM Supernovae with the Very Large Array
The Astrophysical JournalType Ia-CSM supernovae (SNe) are a rare and peculiar subclass of thermonuclear SNe characterized by emission lines of hydrogen or helium, indicative of high-density circumstellar medium (CSM). Their implied mass-loss rates of ∼10 ^−4 –10 ^−1 M _⊙ yr ^−1 (

Flow-Heat Conjugate Numerical Simulation Based on the Time-Domain Method
Xibei Gongye Daxue Xuebao, 2020 For the popups of the applicability of the time-domain based unsteady flow-heat coupling numerical simulation method in physical problems with time-period characteristic, the cases of the plate convection heat transfer and the hollow blunt-nosed blade ...

Evidence for Multiple Shocks from the γ-Ray Emission of RS Ophiuchi
The Astrophysical Journal, 2023 In 2021 August, the Fermi Large Area Telescope, H.E.S.S., and MAGIC detected GeV and TeV γ -ray emission from an outburst of recurrent nova RS Ophiuchi. This detection represents the first very high-energy γ -rays observed from a nova, and it opens a new

Time-Domain Filtering of Metasurfaces [PDF]
Scientific Reports, 2015 AbstractIn general electromagnetic response of each material to a continuous wave does not vary in time domain if the frequency component remains the same. Recently, it turned out that integrating several circuit elements including schottky diodes with periodically metallised surfaces, or the so-called metasurfaces, leads to selectively absorbing ...

FEBS Letters, EarlyView.The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

A 2.9 hr Periodic Radio Transient with an Optical Counterpart
The Astrophysical Journal LettersWe present a long-period radio transient (GLEAM-X J0704−37) discovered to have an optical counterpart, consistent with a cool main-sequence star of spectral type M3. The radio periodicity occurs at the longest period yet found, 2.9 hr, and was discovered

Time-domain studies of M31 [PDF]
Astronomical Review, 2016 M31, our closest neighboring galaxy, is a stepping stone to studies of stellar evolution, star formation, galaxy evolution, and cosmology. However, due to the difficulties of performing photometry in such crowded fields and the lack of wide cameras to encompass the entire galaxy, there has not been a complete census of the stellar contents of M31.

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
