Sonographic Diagnosis of an Intercostal Artery Pseudoaneurysm: A Case Report and Literature Review

Journal of Clinical Ultrasound, EarlyView.
A 63‐year‐old male presented to the emergency department after being found unconscious during a welfare check. Following a prolonged three‐month hospital admission, the patient developed left flank pain. Spectral Doppler ultrasound revealed a large isoechoic lesion with layering echoes, and spectral Doppler demonstrated bidirectional flow.

Low-Complexity Channel Estimation for OTFS via Coordinate Descent Exploiting Delay-Domain Sparsity

IEEE Open Journal of the Communications Society
Orthogonal time frequency space (OTFS) modulation has attracted considerable attention for high-mobility wireless communications; however, accurate channel estimation (CE) remains challenging in the presence of fractional Doppler shifts.

Air-Ground Doppler-delay spread spectrum for dense scattering environments

, 2015
Applications using Air-Ground communications are expected to grow in the future. Low altitude phases of these wireless links are considered sever channels, as they experience huge delay and Doppler spreads, however, they are not yet accurately ...

Complicated Acute Appendicitis Conservatively Treated in Two Patients With Crohn's Disease: The Role of Intestinal Ultrasound and Contrast‐Enhanced Ultrasound

Journal of Clinical Ultrasound, EarlyView.
Intestinal ultrasound and contrast‐enhanced ultrasound were used to diagnose, monitor, and guide conservative treatment of complicated acute appendicitis in two patients with Crohn's disease. Serial imaging enabled early identification of treatment response, allowing long‐term surgery‐free outcomes.

Parallel Coding for Orthogonal Delay-Doppler Division Multiplexing

IEEE Transactions on Communications
This paper proposes a novel parallel coding transmission strategy and an iterative detection and decoding receiver signal processing technique for orthogonal delay-Doppler division multiplexing (ODDM) modulation. Specifically, the proposed approach employs a parallel channel encoding (PCE) scheme that consists of multiple short-length codewords for ...

Complaints Involving Sonographers: What Three Decades of Cases From A Public New Zealand Database Can Teach Us

Journal of Medical Radiation Sciences, EarlyView.
Health consumer complaints to the New Zealand Health and Disability Commissioner involving sonographers are rare, totalling 15 in the last 31 years and averaging 1.5 cases per year over the last decade. A large proportion of complaints involve an undetected finding, obstetric examination and private setting.

The substantial economic burden of rotator cuff pathology: A nationwide cost‐of‐illness study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this study is to evaluate the nationwide economic burden of rotator cuff (RC) pathology by quantifying expenditures related to outpatient consultations including out‐of‐pocket expenses, hospitalisations and occupational insurance claims, within a national healthcare system.

Transoral Ultrasound in the Diagnostic Workup of Peritonsillar Abscess—A Randomized Clinical Trial

The Laryngoscope, EarlyView.
Peritonsillar abscess frequently mimics peritonsillar cellulitis, exposing many patients to unnecessary and often painful blind needle aspirations. In this multicenter randomized clinical trial of 95 patients, adding transoral ultrasound to standard examination reduced needle aspiration attempts by nearly one third.
