Seabed classification in the Gulf of Alaska from acoustic surveys using deep learning

Limnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract High‐resolution mapping of seafloor habitats has wide applications for fisheries, conservation efforts, offshore infrastructure planning, mineral extraction, and scientific modeling. This study leverages existing widespread single‐beam acoustic data and machine learning to create habitat maps for the Gulf of Alaska at a spatial resolution of ...

Channel Dynamics and SNR Tracking in Millimeter Wave Cellular Systems

, 2016
The millimeter wave (mmWave) frequencies are likely to play a significant role in fifth-generation (5G) cellular systems. A key challenge in developing systems in these bands is the potential for rapid channel dynamics: since mmWave signals are blocked ...

Laryngeal Transplantation in Cancer Patients: Evaluation of Surgical Outcomes and Functional Recovery

MedComm, Volume 7, Issue 5, May 2026.
Our pilot clinical study in laryngeal transplantation achieved divergent outcomes: two cases maintained functional speech/swallowing with around 2 year graft survival and have been ongoing, while two succumbed to sepsis (10mo) and hemorrhagic recurrence (11mo).

Factors influencing obstetric ultrasound examination duration in a tertiary fetal center

Pregnancy, Volume 2, Issue 3, May 2026.
Abstract Objective To quantify scan duration across commonly performed obstetric ultrasound examinations in a tertiary fetal imaging center and to evaluate whether exam type, maternal body mass index (BMI), and sonographer experience independently influence scan time. Methods We conducted a retrospective cohort study of singleton pregnancies undergoing

Cardiopulmonary arrest following extradural analgesia and suspected secondary sympathetic blockade in a critically ill dog

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract An 8‐year‐old, male, entire Cocker Spaniel presented to the Queen Mother Hospital for Animals for treatment of an iatrogenic septic uroabdomen secondary to traumatic urinary catheterisation. After initial stabilisation, it underwent diagnostic imaging and definitive surgical correction comprising a cystotomy and bladder reconstruction.

A Machine Learning Parameterization for the Internal Gravity Wave Spectrum

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract We introduce a stochastic model designed to parametrize the spectral properties of internal waves, using two functions that represent the semidiurnal spectral tidal cusps and the energy continuum between the inertial and the buoyancy frequencies.
