Decoding the Heterogeneity of Diffuse Large B‐Cell Lymphomas: A Comprehensive Genetic, Transcriptomic, and Phenotypic Profiling of B‐Cell Lymphoma Cell Lines

Hematological Oncology, Volume 44, Issue 5, September 2026.
ABSTRACT Diffuse large B‐cell lymphoma (DLBCL) is the most prevalent form of non‐Hodgkin lymphoma, exhibiting significant molecular and clinical heterogeneity. Advances in classification integrating phenotypic, genetic, and transcriptomic features have improved diagnosis and prognosis.

Integrated LEO Constellation and In‐Cabin Distribution System for Continuous Aircraft 5G Connectivity

International Journal of Satellite Communications and Networking, Volume 44, Issue 5, Page 594-606, September/October 2026.
ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency ( > 500 ms) and inadequate coverage at high latitudes,

Space‐Time‐Coding Metasurfaces Enabling Programmable Range‐Angle‐Dependent Energy Auto‐Scanning

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
This paper presents a novel energy auto‐scanning system based on a space‐time‐coding metasurface. By applying progressive time‐delayed, time‐varying phase modulation, the system generates non‐uniform, temporally evolving electromagnetic field distributions across both angle and range.

Discretization and Continualization of MIMO Systems

IFAC Proceedings Volumes, 1993
Abstract New numerically robust algorithms are presented for converting linear continuous-time constant-parameter state models into equivalent discrete-time state models ( discretization ) as well as the reverse problem of determining continuous-time models to represent given discrete-time models ( continualization ).
