Dynamic early biomarkers predict outcomes in pediatric Epstein–Barr virus‐associated hemophagocytic lymphohistiocytosis

Pediatric Investigation, EarlyView.
This study elucidates the critical pathogenic mechanisms of pediatric Epstein–Barr virus‐associated hemophagocytic lymphohistiocytosis (EBV‐HLH), where EBV infection triggers a cytokine storm leading to immune cell hyperactivation and tissue damage. Dynamic plasma biomarkers (EBV‐DNA, ferritin, and interferon‐γ) effectively predict treatment response ...

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

International 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 ...

MIMO OTFS in 5G NR Resource Grid

IEEE 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.

Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for

Laponite Network Controls FGF‐2 Release and Drives Functional Nerve Regeneration via 3D‐Printed Nerve Wrap Interfaces

Small Methods, EarlyView.
We developed a 3D‐printed nerve interface integrating a biomimetic nanocomposite hydrogel with sustained delivery of thermostable FGF‐2. The bioactive interface supports Schwann cell activity and myelination while providing a regenerative microenvironment.

Downlink OFDM-FAMA in 5G-NR Systems

IEEE Transactions on Wireless Communications
Fluid antenna multiple access (FAMA), enabled by the fluid antenna system (FAS), offers a new and straightforward solution to massive connectivity. Previous results on FAMA were primarily based on narrowband channels. This paper studies the adoption of FAMA within the fifth-generation (5G) orthogonal frequency division multiplexing (OFDM) framework ...
