Sub‐Terahertz Memristor Switches Using MoS2 by Liquid–Liquid Interface Assembly

Advanced Science, EarlyView.
This work introduces application‐ready sub‐terahertz memristor switches fabricated from electrochemically exfoliated MoS2 nanosheets assembled at a liquid–liquid interface. The devices exhibit robust unipolar resistive switching, low insertion loss, and high isolation across 10–110 GHz.

Low-metallicity Gas on the Outskirts of the Local Group: The Circumgalactic Medium of Sextans B

The Astrophysical Journal
We present a UV absorption-line analysis of the circumgalactic medium (CGM) of Sextans B, a dwarf irregular galaxy at 1.3 Mpc distance on the outer frontier of the Local Group (LG). Using Hubble Space Telescope Cosmic Origins Spectrograph spectroscopy of

Classifying Passing Maneuvers: A Behavioral Approach [PDF]

, 2005
Passing an impeding vehicle on a two-way two-lane roadway is a complex maneuver because of the variety of passing conditions and driver behavior. In this study, the supposition that passing maneuvers can be classified on the basis of a quantitative ...

Cobalt Single‐Atom Nanozyme for Enhanced Intestinal Radioprotection and Tumor Radiosensitization via Bidirectional ROS Modulation

Advanced Science, EarlyView.
Orally administered, pH‐responsive Co‐SAN exerts dual functions: in the alkaline intestinal milieu, it scavenges reactive oxygen species (ROS) and suppresses the PI3K/AKT pathway and NETs formation, thus providing radioprotection; whereas in the acidic tumor microenvironment, it generates ROS and alleviates hypoxia, thereby enhancing radiosensitization.

Is the nitrogen-rich source PN K4-47 a true planetary nebula?

Astronomy & Astrophysics
Context. The object K4-47 is a young planetary nebula that exhibits low-ionisation structures in the form of two ‘lobes’. The unusual chemistry of the nebula has raised questions about whether K4-47 is a true planetary nebula or if the origins are more ...

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

Advanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

The Truncated Circumgalactic Medium of the Large Magellanic Cloud

The Astrophysical Journal Letters
The Large Magellanic Cloud (LMC) is the nearest massive galaxy to the Milky Way (MW). Its circumgalactic medium (CGM) is complex and multiphase, containing both stripped H i structures like the Magellanic Stream and Bridge and a diffuse warm corona seen ...

Motorcycle characteristics for sight distance investigation on exclusive motorcycle lanes. [PDF]

, 2011
In developing Association of Southeast Asian Nations (ASEAN) countries, the motorcycle is a popular means of transportation because it is cheap and provides flexible door-to-door mobility. However, motorcyclists are also highly involved in road accidents.

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

Advanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.
