3D simulations of self-propelled, reconstructed jellyfish using vortex methods [PDF]
arXiv, 2009 We present simulations of the vortex dynamics associated with the self-propelled motion of jellyfish. The geometry is obtained from image segmentation of video recordings from live jellyfish. The numerical simulations are performed using three-dimensional viscous, vortex particle methods with Brinkman penalization to impose the kinematics of the ...

Clinical Medicine, 2016 This chapter outlines diagnostic clues of importance in the history in stroke patients and how a stroke or transient ischemic attack may be distinguished from migraine, seizure, syncope, and amyloid spells. Disorders that mimic a stroke are described, as well as focal cortical and brainstem syndromes and the one-and-a-half syndrome. Features permitting

Targeted walking training of patients in the early recovery period of cerebral stroke (preliminary research) [PDF]
Клиническая практика, 2021 Background: Currently, training of the gait function for patients with cerebral stroke using the biofeedback technology is an independent, effective, and promising method. The most common training and exposure parameters are the gait speed, cycle length,

Stroke Extraction of Chinese Character Based on Deep Structure Deformable Image Registration [PDF]
Proceedings of the AAAI Conference on Artificial Intelligence,
37(1), 1360-1367, 2023, 2023 Stroke extraction of Chinese characters plays an important role in the field of character recognition and generation. The most existing character stroke extraction methods focus on image morphological features. These methods usually lead to errors of cross strokes extraction and stroke matching due to rarely using stroke semantics and prior information.

Swiss Medical Forum ‒ Schweizerisches Medizin-Forum, 2020 Stroke is a major cause of death and disability globally. Diagnosis depends on clinical features and brain imaging to differentiate between ischaemic stroke and intracerebral haemorrhage. Non-contrast CT can exclude haemorrhage, but the addition of CT perfusion imaging and angiography allows a positive diagnosis of ischaemic stroke versus mimics and ...
