SMTC Configuration and Window Adjustment Strategies for Beam Hopping in NR‐NTN

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Beam hopping is an effective transmission strategy for nonterrestrial networks (NTNs), enabling satellites to allocate limited power and spectrum resources across different geographical regions over time. However, in NR‐based NTN systems, beam hopping complicates synchronization monitoring because synchronization signal block (SSB) arrivals ...

Cardiomyocyte Membrane‐Camouflaged Spinach Nano‐Thylakoids Enhance Myocardial Energy Metabolism and Ameliorate Heart Failure

open access: yesSmall, EarlyView.
Schematic illustration of the construction of MM‐NTU, its cardiac‐targeting behavior, and its light‐activated therapeutic mechanism. Thylakoids isolated from spinach chloroplasts were processed into nano‐thylakoid units (NTU) and further camouflaged with cardiomyocyte membranes to generate MM‐NTU.

Robust Reconstruction of Atomic Force Microscopy Tip Shape From Force‐Indentation Curves

open access: yesSmall Methods, EarlyView.
A robust method, termed Piecewise Inverse Force Curve Analysis (PIFCA), is introduced for reconstructing the shape of atomic force microscopy (AFM) tips. The approach relies on piecewise linear axisymmetric approximation of the tip shape based on the analysis of force versus indentation depth curves acquired on a soft reference sample.

Characterization of Nonmetallic Inclusions in Ce‐Containing Steels at the Submicroscopic Level

open access: yessteel research international, EarlyView.
Accurate detection of nonmetallic inclusions (NMIs) is crucial for ensuring high standards in steel cleanness and properties. Optimized automated SEM/EDS measurements are required for evaluating Ce‐containing NMIs. This study enhances the characterization of submicroscopic NMI in Ce‐alloyed ultralow‐carbon, high‐manganese, and electrical steels ...
