Polarimetric and spectropolarimetric observations with FoReRo2: Instrument overview and standard star monitoring★

Astronomy & Astrophysics
In this paper, we present a description and characterisation of the 2-Channel Focal Reducer Rozhen (FoReRo2), with an emphasis on its polarimetric and spectropolarimetric observation modes.

Neuromorphic Denoising with Fully Analog Memristive In‐Memory Computing

Advanced Intelligent Systems, EarlyView.
This article borrows the concepts of episodic memory in human brains to experimentally implement a memristor‐based neuromorphic denoising process. A homogeneous memristor processing unit is experimentally demonstrated for both temporal storage and neural network computation, imitating the synapses in the human brain.

X-Rays from RS Ophiuchi’s 2021 Eruption: Shocks In and Out of Ionization Equilibrium

The Astrophysical Journal
The recurrent nova RS Ophiuchi (RS Oph) underwent its most recent eruption on 2021 August 8 and became the first nova to produce both detectable GeV and TeV emission.

Classical and Recurrent Nova Outbursts

, 2011
Over the last 40 years, multi-frequency observations, coupled with advances in theoretical modelling, have led to a much fuller understanding of the nova phenomenon. Here I give a brief review of the current state of knowledge of Classical and Recurrent Novae including their central systems; the causes and consequences of their outbursts; sub-types ...

Genome‐Wide Association Study of Symptom Change Following Cognitive Behavioral Therapy for Common Mental Disorders

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Cognitive behavioral therapy (CBT) is a well‐established, evidence‐based treatment for common mental disorders such as depression, anxiety disorders, and obsessive‐compulsive disorder (OCD). However, treatment outcomes vary widely, and a substantial proportion of patients do not achieve sufficient improvement.

The Accelerating Decline of the Mass Transfer Rate in the Recurrent Nova T Pyxidis

The Astrophysical Journal
The recurrent nova T Pyxidis (T Pyx) has erupted six times since 1890, with its last outburst in 2011, and the relatively short recurrence time between classical nova explosions indicates that T Pyx must have a massive white dwarf (WD) accreting at a ...

Association between Recurrent Novae and Nova Super-Remnants

Proceedings of The Golden Age of Cataclysmic Variables and Related Objects - VI — PoS(GOLDEN2023)
Nova super-remnants (NSRs) are substantially extended structures (up to ~130 parsecs across) encompassing recurrent novae. NSRs grow as a result of frequent nova eruptions transporting vast quantities of the locally surrounding interstellar medium away from the binary system over many millennia into a thin high-density shell, as the central white dwarf

Multi‐Responsive Bowl‐Shaped Janus Nanomotors Based on Polyitaconic acid/Polypyrrole on the Surface of Iron Oxide Nanoparticles with Chemical, Electrical, and Magnetic Field Actuation for Targeted Drug Delivery Applications

Advanced NanoBiomed Research, EarlyView.
Bowl‐shaped Janus nanomotors with platinum, iron oxide, and polypyrrole integrate catalytic, magnetic, and electric propulsion for targeted drug delivery. They demonstrate controlled, directional motion under varying pH and hydrogen peroxide conditions, with optimal performance in neutral media.

Multiwavelength Observations of Multiple Eruptions of the Recurrent Nova M31N 2008-12a

The Astrophysical Journal
We report the optical, UV, and soft X-ray observations of the 2017–2022 eruptions of the recurrent nova M31N 2008-12a. We find a cusp feature in the $r^{\prime} $ - and $i^{\prime} $ -band light curves close to the peak, which could be related to jets ...
