An Active Shaping Reflector Method for Space-Borne Membrane Reflector Antennas
IEEE AccessConventional space-borne antenna shaping designs predominantly rely on a pre-defined reflector geometry, which lacks the capability to adapt to varying multi-stage service requirements once in orbit.

Aging and Cancer, EarlyView.This systematic review synthesizes prognostic models for survival and recurrence in resected non‐small cell lung cancer. While many models demonstrate moderate to good discrimination, few are externally validated and reporting quality is variable, limiting clinical applicability and highlighting the need for robust, transparent model development ...

Shared Genetic Effects and Antagonistic Pleiotropy Between Multiple Sclerosis and Common Cancers
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Epidemiologic studies have reported inconsistent altered cancer risk in individuals with multiple sclerosis (MS). Factors such as immune dysregulation, comorbidities, and disease‐modifying therapies may contribute to this variability.

Immune‐Driven Expression in Inclusion Body Myositis With T‐Cell Large Granular Lymphocytic Leukemia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives T‐cell large granular lymphocytic leukemia (T‐LGLL), reported in up to 58% of inclusion body myositis (IBM) patients, is a rare leukemia of cytotoxic or less commonly helper T cells. The range of myopathies in T‐LGLL and the impact of coexisting T‐LGLL in IBM are not well understood. Our objectives are to investigate the spectrum of

Radiation patterns of paraboloids
, 1942 This report contains the results of a study of various methods of exciting paraboloids, made in an effort to obtain methods which would give usable radiation patterns and at the same time permit wobbling the beam for split-beam direction finding. The curves attached to this report give representative radiation patterns and much of the information ...
