We consider a team of k identical, oblivious, and semi-synchronous mobile robots that are able to sense (i.e., view) their environment, yet are unable to communicate, and evolve on a constrained path. Previous results in this weak scenario show that initial symmetry yields high lower bounds when problems are to be solved by deterministic robots. In this paper, we initiate research on probabilis...

Let D be a connected region inside a simple polygon, P . We define the angle hull of D, AH(D), to be the set of all points in P that can see two points of D at a right angle. We show that the perimeter of AH(D) cannot exceed in length the perimeter of D by more than a factor of 2. This upper bound is tight. Our result can be generalized to angles different from 90◦, and to settings where region...

We propose an abstract framework for Design Space Exploration (DSE) in the context of model-based embedded system development. The goal is to enable the integration of a set of concrete DSE methods addressing different system characteristics and design goals while still having a common understanding of design artifacts.

Purpose The purpose of this study is to evaluate the efficacy and safety stimulating vagus nerve in patients with disorders consciousness (DOCs). Methods A comprehensive systematic review was conducted, encompassing search databases such as PubMed, CENTRAL, EMBASE PEDro from their inception until July 2023. Additionally, manual searches exploration grey literature were performed. conducted inde...

Recurrent carpal tunnel syndrome occurs in up to 12% of cases after carpal tunnel release. Recurrent carpal tunnel syndrome is defined as recurrence of classic symptoms confirmed by electrodiagnostic studies after a symptom-free interval of a minimum of 6 months, as opposed to persistent carpal tunnel syndrome, where a symptom-free interval never occurs after carpal tunnel release, which is att...

THE diagnosis of progressive unilateral visual failure, when occurring as a solitary symptom in association with a visual field defect and when all routine investigations are negative, presents many difficulties. Amongst the conditions to be considered are retinal vascular disease, chronic simple glaucoma, atypical forms of toxic amblyopia, optic neuritis, and optic nerve compression. Meadows (...

AIm: Treatment options for traumatic brachial plexus injuries include nerve grafting, or neurotization. The type of lesion and the reconstructive procedures affect functional results and postoperative pain relief. mAterIAl and methOds: A total number of twenty five patients suffering from post-traumatic brachial plexus injury were included in the study. The patients underwent exploration and pr...

A 20-year-old man suffered the combined axillary and suprascapular nerve palsies associated with scapulothoracic dissociation by motorcycle accident. The dislocated shoulder girdle was reduced and stabilized with osteosynthesis of the fractured clavicle and reattachment of the trapezius avulsed from the scapular spine for removal of continuous traction force to these damaged nerves. Because of ...

INTRODUCTION Spontaneous radial palsy is a not rare finding in hand clinics. The anatomy of the radial nerve renders it prone to pressure paralysis as often called "Saturday night palsy". This problem is a transient nerve lesion and an acute one but the case presented here is very unusual in that it seems this entity can also occur as an acute on chronic situation with neuroma formation. CASE...
