When Chronic Pain Clouds Acute Diagnosis: Femoral Shaft Osteonecrosis With Superimposed Pseudomonas Osteomyelitis in a Medically Complex Patient

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT In medically complex patients with chronic pain, new or worsening symptoms should prompt careful reassessment. Avascular necrosis, particularly in the setting of prolonged steroid use, may be overlooked due to diagnostic overshadowing. Timely recognition requires multidisciplinary collaboration and vigilance to distinguish acute pathology from

On ASER Analysis of Energy Efficient Modulation Schemes for a Device-to-Device MIMO Relay Network

IEEE Access, 2020
In this paper, we investigate the performance of a device-to-device (D2D) multiple-input and multiple-output (MIMO) communications using an amplify-and-forward relaying for various energy-efficient modulation schemes.

Fetal Instability and Resuscitative Management During Fetal Intervention: A Retrospective, Descriptive Analysis of 245 Fetal Cardiac and Spina Bifida Procedures

Prenatal Diagnosis, Volume 46, Issue 7, Page 1104-1111, June 2026.
ABSTRACT Objective The heterogeneity of fetal surgery has led to variability in the nature and frequency of fetal instability. Understanding these differences is critical for optimizing management. Methods We reviewed all fetal atrial septal interventions (FASI) and fetoscopic myelomeningocele (fMMC) repairs with fetal instability performed at our ...

Symbol‐Level GRAND‐Assisted Detection for Polar‐Coded Spatial Modulation in MIMO Systems

International Journal of Communication Systems, Volume 39, Issue 7, 10 May 2026.
This research presents an integrated polar‐coded spatial modulation (PCSM) transceiver scheme for MIMO transmission over Rayleigh fading channels. The proposed architecture employs linear spatial signal processing for antenna and symbol estimation, followed by symbol‐level guessing random additive noise decoding (symbol‐level GRAND)–assisted detection ...

Variable rate QAM for mobile radio [PDF]

IEEE Transactions on Communications, 1995
Quadrature amplitude modulation (QAM) schemes which vary the number of modulation levels in accordance with the mobile radio fading channel variations are investigated. Important parameters considered are the fading rate and the block size used. We describe how the adaptive QAM modems can be employed and consider their use in a DECT-like TDD packet ...

Defence traits vary across leaf ages in the thistles (Cardueae)

Functional Ecology, Volume 40, Issue 5, Page 1517-1531, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants produce a variety of structural and chemical defences to deter herbivores, which can covary across every scale of biological organization. Along these lines, it has been suggested that young leaves differ from old leaves in their defence strategies, but studies ...
