herein, we report the f-18 fluorodeoxyglucose (18f-fdg) positron emission tomography (pet)/computed tomography (ct) findings of a benign solitary fibrous tumor (sft) of the kidney. the patient was a 63-year-old woman with a mass in the right kidney (10×9.7 cm), incidentally found on ct images. the ct scan showed a lobulated tumor arising from the hilum of the right kidney. the tumor consisted o...

background: computed tomography (ct) scan is one the most useful devices in chest imaging. ct scan can be used in mediastinal abnormality, lungs, and pleural evaluations. according to the high prevalence and different causes of pulmonary nodules, we designed this study to evaluate the prevalence and the types of pulmonary nodules in noncancerous patients who underwent chest multi-detector ct (m...

dust acoustic (da) solitary waves are investigated in an unmagnetized dusty plasma comprising of fluid warm dust particles and kappa distributed ions. we assume the electron number density to be sufficiently depleted in this fluid model, i.e., ne  nd . we consider the usual ad hoc damping term, involving the damping rate  due to the dust–neutral collisions; and derived the modified dis...

Solitary Plasmacytoma of the Skull (SPS) is very rare and only 35 cases have been reported in the English literature. It remains controversial whether a solitary plasmacytoma of the skull is essentially identical with a Solitary Plasmacytoma of Bone (SPB) or not. A solitary plasmacytoma of bone, which includes a solitary plasmacytoma of the skull, is characterized by a radiologically solitary b...

A model equation for gravity-capillary waves in deep water is proposed. This model is a quadratic approximation of the deep water potential flow equations and has wavepacket-type solitary wave solutions. The model equation supports line solitary waves which are spatially localized in the direction of propagation and constant in the transverse direction, and lump solitary waves which are spatial...

3 forms of solitude were studied in young children--reticence (onlooker and unoccupied behavior), solitary-passive behavior (solitary-constructive and -exploratory play), and solitary-active behavior (solitary-functional and -dramatic play). 48 4-year-old children grouped in quartets of same-sex unfamiliar peers were observed in several situations. Mothers completed the Colorado Temperament Inv...

The characteristics of arbitrary amplitude dust ion acoustic solitary waves (DIASWs) are studied in unmagnetized dusty plasmas whose constituents are cold uid ions, nonextensive electrons and stationary negative/positive dust particles. The pseudopotential approach has been used to investigate the structure of localized waves. It is found that, solitary waves exist in a definite interval for th...

The existence of solitary-wave solutions to the three-dimensional water-wave problem with strong surface-tension effects is predicted by the KP-I model equation. The term solitary wave describes any solution which has a pulse-like profile in its direction of propagation, and the KP-I equation admits explicit solutions for three different types of solitary wave. A line solitary wave is spatially...

OBJECTIVE The aim of this study was to evaluate the usefulness of a new commercially available computer-aided diagnosis (CAD) system with an automated method of detecting nodules due to lung cancers on chest radiograph. MATERIALS AND METHODS For patients with cancer, 45 cases with solitary lung nodules up to 25 mm in diameter (nodule size range, 8-25 mm in diameter; mean, 18 mm; median, 20 mm...
