Automated detection of bicycle helmets using deep learning

Journal of Cycling and Micromobility Research
Bicycle helmets are a main measure for injury prevention in case of a crash and are a central variable in transport safety studies. Despite this, helmet use data is only collected sporadically, as the observation of helmet use in traffic by human ...

Toward Inter‐Sonication Monitoring of Skull and Brain Temperatures in Transcranial MRgFUS Using a 3D Stack‐of‐Spirals Sequence

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an MRI approach for simultaneous skull and brain temperature monitoring between sonications in transcranial MR‐guided focused ultrasound (MRgFUS) surgeries. Methods A 3D stack‐of‐spirals dual‐echo ultra‐short TE (UTE) sequence incorporating fat suppression, spiral deblurring, trajectory measurement, and B1 correction was ...

Helmet Non-invasive Ventilation in a Do-Not-Intubate Patient with Acute Respiratory Failure

Tokyo Women's Medical University Journal, 2020
Non-invasive ventilation (NIV) is occasionally used for management of acute respiratory failure in a do-not-intubate (DNI) patient, when conventional oxygen administration or high-flow nasal cannula fail to improve respiratory distress.

Reducing Inequalities Through Sustainable Digital Design: Assistive Technology Development for SDG 3 and SDG 10

Sustainable Development, EarlyView.
ABSTRACT Limited access to appropriate assistive technologies (AT) remains a major barrier to health, well‐being, and social inclusion, particularly among vulnerable and marginalised populations. Addressing this challenge is central to Sustainable Development Goal (SDG) 3 (Good Health and Well‐being) and SDG 10 (Reduced Inequalities).
