X-rays from shock-heated gas in recurrent-nova remnants Nested nova shells in a structured circumstellar medium

Astronomy & Astrophysics
Context. Recurrent symbiotic novae such as RS Oph show extended X-ray emission associated with the interaction of nova ejecta with the circumstellar environment. Aims.

Combined Immune‐Peptide Nanofiber with HSP70/AKT/mTOR Axis Blockade Enhances Photothermal Immunotherapy, Inhibiting Tumor Growth and Recurrence

Advanced Science, EarlyView.
A carrier‐free peptide‐guided PSP@IR‐CF3 nanofiber system integrates PD‐L1 targeting and photothermal immunotherapy for enhanced cancer treatment. By revealing PTIT‐induced activation of the HSP70/AKT/mTOR pathway and incorporating mTOR inhibition, this strategy effectively overcomes therapeutic resistance and prevents tumor recurrence, providing a ...

Hydrodynamic Simulations of Oxygen–Neon Classical Novae as Galactic 7Li Producers and Potential Accretion-induced Collapse Progenitors

The Astrophysical Journal
We report on studies of classical nova (CN) explosions where we follow the evolution of thermonuclear runaways (TNRs) on oxygen–neon (ONe) white dwarfs (WDs).

MoS2 Memristors Made by Liquid–Liquid Interface Assembly and Ultraprecise Metal Printing

Advanced Electronic Materials, EarlyView.
A cleanroom‐free, fully additive fabrication route combines ultraprecise printed silver electrodes with Langmuir–Schaefer‐deposited bilayer MoS2 to realize ultralow‐power resistive switching devices. The resulting microscale memories exhibit low operating voltages, a large memory window, stable retention and endurance, demonstrating a scalable and cost‐

Novae: An Important Source of Lithium in the Galaxy

The Astrophysical Journal
The source of the Galactic lithium (Li) has long been a puzzle. With the discovery of Li in novae, extensive research has been conducted. However, there still exists a significant disparity between the observed abundance of Li in novae and the existing ...

Inverse Design of Electromagnetic‐Induced Transparency Metasurface Using Conditional Generative Adversarial Network

Advanced Intelligent Systems, EarlyView.
This work develops a CGAN‐based metasurface inverse design method. It adopts an integrated workflow of pixel‐based graphical modeling, simulation, and GAF transform for automatic, batch metasurface dataset construction. With a U‐Net architecture, the CGAN generates high‐resolution, high‐fidelity metasurface structures. EIT verification achieves over 90%

Challenging Classical Paradigms: Recurrent Nova M31N 2017-01e, a BeWD System in M31?

The Astrophysical Journal
M31N 2017-01e is the second-fastest recurrent nova known, with a recurrence period of 2.5 yr in the Andromeda galaxy (M31). This system exhibits a unique combination of properties: a low outburst amplitude (∼3 mag), starkly contrasting with known ...

Observations and simulations of recurrent novae: U Sco and V394 CrA [PDF]

, 1988
Observations and analysis of the Aug. 1987 outburst of the recurrent nova V394 CrA are presented. This nova is extremely fast and its outburst characteristics closely resemble those of the recurrent nova U Sco.

Heterozygous Variants in LRP1 Cause a Neurodevelopmental Disorder With Congenital Heart Defects

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT LRP1 encodes the low‐density lipoprotein (LDL) receptor‐related protein 1 (LRP1), a transmembrane protein involved in endocytosis and activation of multiple signaling pathways. LRP1 variants have been implicated in the pathogenesis of congenital heart defects (CHD), Alzheimer's disease, and neurodevelopmental disorders (NDD).
