Space is essential to our modern way of life; but as the number satellites in orbit increases, so does chance collisions and subsequent debris. This creation debris increases probability new a positive feedback loop, potentially leading runaway growth called Kessler Syndrome. To investigate this problem, simulation Low Earth Orbit has been created. Results show exponential initially decrease ca...

Abstract The paper explores the evolution of private powers in digital landscape, developing a quadrangular systematisation such phenomenon based on four main aspects: space, values, (private) actors, and (digital) constitutional remedies. Taking trans‐Atlantic approach, shows how these categories, typical constitutionalism, apply to context Internet new technologies both United States Europe. ...

The work is devoted to parametric investigations of the krypton flow in a conical micronozzle when flowing into region with low pressure. features flows are studied at various values stagnation pressure pre-nozzle volume, including occurrence condensed phase flow. Mathematical modeling was carried out on basis numerical solution complete system Navier-Stokes equations, supplemented by equation ...

PURPOSE To report a case of perfluorocarbon liquid (PFCL) migration into the subarachnoid space at the time of vitreoretinal surgery in a patient with morning glory syndrome associated retinal detachment. CASE REPORT A 9-year-old girl underwent pars plana vitrectomy and silicone oil injection for retinal detachment associated with morning glory syndrome. PFCL was used for retinal stabilizatio...

Quadrilateral space syndrome is an uncommon injury. The true prevalence is unknown because of a lack of literature and possible misdiagnosis. Prevalence may increase as knowledge of the syndrome increases. The case is presented of a recreational triathlete who had a spontaneous onset of quadrilateral space syndrome. The diagnosis was made by physical examination and confirmed with magnetic reso...

BACKGROUND AND PURPOSE Incidental MR imaging findings resembling MS in asymptomatic individuals, fulfilling the Okuda criteria, are termed "radiologically isolated syndrome." Those with radiologically isolated syndrome are at high risk of their condition converting to MS. The epidemiology of radiologically isolated syndrome remains largely unknown, and there are no population-based studies, to ...

We present a method for direction field design on surface and volumetric meshes supporting non-orthogonality. Our approach is generalization of the representation 3D cross fields in spherical harmonic basis. As such it induces geometrically meaningful measure smoothness, allows orthogonality control by simple parameter enables orientation constraints single direction. To best our knowledge this...
