COVID-19 diagnosis: A comprehensive review of pre-trained deep learning models based on feature extraction algorithm.

Due to the augmented rise of COVID-19, clinical specialists are looking for fast faultless diagnosis strategies to restrict Covid spread while attempting to lessen the computational complexity. In this way, swift diagnosis techniques for COVID-19 with high precision can offer valuable aid to clinical specialists. RT- PCR test is an expensive and tedious COVID diagnosis technique in practice.

Portal Vein Thrombosis in the Setting of Newly Diagnosed Cushing's Syndrome.

The hallmark manifestations of Cushing's syndrome (CS) are well known, but hypercoagulability is perhaps least recognized. Patients with CS are at increased risk of both spontaneous and postoperative thromboembolism, with the significant majority of events occurring in the lower extremity and pulmonary venous circulations. We present a case of portal vein thrombosis (PVT) occurring in the setting of newly diagnosed CS due to a left adrenal adenoma.

A retrospective study of the natural history of endogenous subclinical hyperthyroidism.

Objective: The treatment of subclinical hyperthyroidism is controversial because the natural history is uncertain. We undertook a retrospective study to examine the natural history of endogenous subclinical hyperthyroidism.

Methods: Between 2002 and 2006, we identified 116 patients with thyroid-stimulating hormone (TSH) concentrations <0.

Time-resolved measurements of supersonic fuel sprays using synchrotron X-rays.

A time-resolved radiographic technique has been developed for probing the fuel distribution close to the nozzle of a high-pressure single-hole diesel injector. The measurement was made using X-ray absorption of monochromatic synchrotron-generated radiation, allowing quantitative determination of the fuel distribution in this optically impenetrable region with a time resolution of better than 1 micros. These quantitative measurements constitute the most detailed near-nozzle study of a fuel spray to date.
