Gain-Boosted X-Band GaN Low-Noise Amplifier MMIC With Y/preZ-Embedding Network

open access: yesIEEE Access
This study improves the performance of an X-band gallium nitride (GaN) low-noise amplifier (LNA) using a gain-boosting embedding network. Using a gain-plane graph, analytical expressions are derived from the Z-parameters of the transistor to determine ...

Non-dissipative thermal transport in the massive regimes of the XXZ chain

open access: yes, 2003
We present exact results on the thermal conductivity of the one-dimensional spin-1/2 XXZ model in the massive antiferromagnetic and ferromagnetic regimes. The thermal Drude weight is calculated by a lattice path integral formulation.

Aptamer‐Functionalized Nanocarriers for Bone and Joint Diseases: Engineering Design Rules and Translational Roadmap

open access: yesSmall Science, Volume 6, Issue 5, May 2026.
Aptamer‐functionalized nanocarriers represent a versatile platform for targeted therapy in bone and joint diseases. This review presents five complementary design strategies: free aptamers for soluble targets, bispecific multivalent constructs for enhanced avidity, nanoparticle‐conjugated aptamers for selective tissue accumulation, aptamer‐based ...

Small Grain Forage Trial Nitrogen Fertility and Harvest Date [PDF]

open access: yes, 2012
Cool season annual forages, such as cereal grains, can provide early season grazing as well as high quality stored feed. However, it is unclear if quality and yield of these forages could be improved through better fertility management.

Telomere Dysfunction and Proteostasis Decline Define Distinct Pathways of Cellular Senescence in the Human Respiratory Tract

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Telomere shortening occurs with age in the respiratory epithelium, but telomere dysfunction‐induced foci (TIF) accumulate only late in life. In contrast, proteostasis decline emerges earlier and correlates with functional impairment, suggesting it may be a primary driver of cellular senescence during physiological aging.

Identification of Urinary Exosomal microRNAs Associated With Subclinical Acute T‐Cell‐Mediated Rejection in Kidney Transplant Recipients

open access: yesClinical and Translational Science, Volume 19, Issue 5, May 2026.
ABSTRACT This study aimed to evaluate the diagnostic utility of urinary exosomal microRNAs (miRNAs) in subclinical rejection following kidney transplantation by comparing miRNA expression profiles in urinary exosomes between patients with no evidence of rejection and patients with subclinical T‐cell‐mediated rejection (sc‐TCMR), as confirmed by ...

OnabotulinumtoxinA treatment among diverse racial groups: Post hoc analysis of the phase 4 Chronic migraine OnabotulinuMtoxinA Prolonged Efficacy open‐Label (COMPEL) trial

open access: yesHeadache: The Journal of Head and Face Pain, Volume 66, Issue 5, Page 1069-1080, May 2026.
Abstract Objective Examine treatment responses to and safety of onabotulinumtoxinA for the preventive treatment of chronic migraine (CM) among diverse racial groups. Background Evidence suggests there are differences in headache treatment patterns, symptom profiles, and burden based on race.
