In this paper using strongly duplexes we introduce a new class of (semi)hypergroups. The associated (semi)hypergroup from a strongly duplex is called duplex (semi)hypergroup. Two computer programs written in MATLAB show that the two groups $Z_{2n}$ and $Z_{n}times Z_{2}$ produce a strongly duplex and its associated hypergroup is a complementary feasible hypergroup.
BACKGROUND AND PURPOSE The purpose of this study was to describe typical ultrasonographic findings of vertebral arteries in patients affected by giant cell arteritis. METHODS Color duplex sonography was used to asses the cervical arteries within 24 hours from stroke onset in 1237 patients. Vertebral arteritis was considered if concentric, homogeneous, and smooth hypoechogenic mural thickening...
Popliteal cyst, also called Baker's cyst, is a popliteal fossa enlargement filled with synovial fluid. Baker's cysts can be symptomatic and cause considerable pathologies such as thrombophlebitis, compartment syndrome and even nerve entrapment. It is the most common nonvascular pathology seen in the popliteal fossa but clinically indistinguishable from deep vein thrombosis. The aim of the prese...
INTRODUCTION Emergency physician-performed compression ultrasonography focuses primarily on the evaluation of the proximal veins of the lower extremity in patients with suspected deep venous thrombosis (DVT). A detailed sonographic evaluation of lower extremity is not performed. The objective of this study was to determine the prevalence of non-thrombotic findings on comprehensive lower extremi...
