Diagnostic accuracy of Doppler ultrasound technique of the penile arteries in correlation to selective arteriography [PDF]

, 1988
In 63% of 265 patients with erectile dysfunction a relevant arterial inflow disturbance was found by Doppler ultrasound examination. Correlation between Doppler and arteriography in 58 patients showed an accuracy of 95% in detecting penile arteries and ...

An Intelligent Piezoelectric System Integrating Self‐Sensing and Autonomous Operation for Adaptive Vibration Control

Advanced Intelligent Systems, EarlyView.
An intelligent piezoelectric vibration control system integrating self‐sensing, autonomous operation, and adaptive bias‐flip synchronized switching damping (SSD) is developed. The system detects vibration extrema, executes synchronized switching control, and autonomously establishes the bias voltage without external sensing instruments, achieving ...

Severe ADEM‐Like Neuroinflammatory Disease and Cerebrovascular Fragility With Recurrent Pseudoaneurysms and Moyamoya in a Familial Germline CBL Mutation: Expanding the Clinical Phenotype

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous germline variants in CBL disrupt its function as a negative regulator of the Ras/MAPK pathway, classically predisposing to Juvenile myelomonocytic leukemia (JMML) and moyamoya. We describe two affected siblings carrying a paternally inherited CBL variant (c.1210 T> C, p.

Self‐Assembled Telecom Color Centers in Silicon and Their Growth Environment

Advanced Physics Research, EarlyView.
Influence of the growth pressure during the formation of self‐assembled color centers in silicon grown by molecular beam epitaxy at ultra‐low temperatures on the color center's photoluminescence spectral signature. The growth pressure crucially determines color center selectivity, as evidenced by G‐centers, W‐centers, and T‐centers, matrix purity, and ...

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

The Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.
