Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Tetraspanin‐ESCRT sorting drives miR‐29b packaging into extracellular vesicles to reverse fibrosis in intrauterine adhesions

open access: yesBMEMat, EarlyView.
MiR‐29b is enriched in extracellular vesicles (EVs) via a tetraspanin transporter‐dependent endocytosis and sorting complex required for the endosomal transport (ESCRT)‐dependent pathway. These EVs target the 3′ untranslated region (3′UTR) of TGFB2, thereby inhibiting the TGF‐β/Smad3 signaling pathway and repairing endometrial damage in intrauterine ...

Detecting Airborne Objects with 5G NR Radars

open access: yesMILCOM 2025 - 2025 IEEE Military Communications Conference (MILCOM)
The integration of sensing capabilities into 5G New Radio (5G NR) networks offers an opportunity to enable the detection of airborne objects without the need for dedicated radars. This paper investigates the feasibility of using standardized Positioning Reference Signals (PRS) to detect UAVs in Urban Micro (UMi) and Urban Macro (UMa) propagation ...

Modular One‐Pot Access to π‐Expanded Tetrakis(Phenothiazinyl)‐Silanes With Broadly Tunable Redox and Emission Properties

open access: yesChemistry – A European Journal, EarlyView.
A library of 21 tetrakis(phenothiazinyl)‐substituted silanes with broadly variable substituent decoration, which are fully reversible multistage redox systems with intense tunable emission from deep blue to yellow–green (441–533 nm), was rapidly synthesized by bromine–lithium exchange/borylation–Suzuki coupling of tetrakis(4‐bromophenyl)silane or by ...

Dominant Lithium‐Ion Conduction and Desolvation Regulation Enabled by Lithiated Monodisperse Nanospheres Composite Separator for High‐Nickel Lithium Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
To match high‐nickel lithium batteries, a composite separator is designed using a sulfonation‐lithiation nanosphere coating modification strategy. The composite separator can enhance the selectivity of lithium‐ion transport, accelerate Li+‐desolvation, and capture Ni, Co, and Mn ions.

MIMO OTFS in 5G NR Resource Grid

open access: yesIEEE Communications Letters
In this letter, we describe a method for transmitting multiple input multiple output (MIMO) orthogonal time frequency space (OTFS) and discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) in 5G new radio (NR) resource grid and also present their corresponding receivers.

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

open access: yesFlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...
