The three-dimensional Gaussian core model (GCM) for soft-matter systems has repulsive interparticle interaction potential ? ( r ) = ? exp [ ? / ? 2 ] , with the distance between a pair of atoms, and positive constants setting energy length scales, respectively. is mostly soft in character, without typical hard present fluid models. We work out thermodynamic Ricci curvature scalar R GCM, particu...

BACKGROUND AND PURPOSE Identification of the central region is of special importance to avoid neurologic deficits in brain surgery. Brain surface reformatted images (Mercator view) map the frontoparietal brain surface in 1 view and provide a synopsis of the most important landmarks. In this view, the U-shaped subcentral gyrus appears as a distinctive anatomic structure enclosing the Sylvian end...

A retrospective study was performed to determine the clinical and pathologic features, etiology, and outcome of children with the reversal sign. The reversal sign, a striking CT finding, probably represents a diffuse, anoxic/ischemic cerebral injury. CT features of the reversal sign are diffusely decreased density of cerebral cortical gray and white matter with a decreased or lost gray/white ma...

There is now growing evidence that parkinsonism and other extrapyramidal signs are highly prevalent in patients with first-episode psychosis who have never been exposed to antipsychotic drugs. However, the neurocognitive correlates of parkinsonism in this population remained to be clarified. A sample comprising 100 consecutive drug-naive patients with first-episode psychosis were enrolled on th...

  Bronchiolo-alveolar carcinoma with subcutaneous chest wall metastasis is a very rare presentation. A case of 36- year-old male with metastatic subcutaneous chest nodule of bronchiolo-alveolar carcinoma, diagnosed by fine needle aspiration cytology, is reported here. Cutaneous metastases are of diagnostic importance because they may be the first manifestation of an undiscovered internal malig...

We report on the radiological findings in a series of 871 consecutive primary condylar knee replacements followed up for an average of four years. A new radiological sign has been identified, consisting of a smoothly tapering wedge of cement visible beneath the horizontal portion of the tibial component on the anteroposterior radiograph. This was found in 25.4% of our cases and appears to indic...

STUDY OBJECTIVE To describe and prospectively evaluate a new radiologic sign with the potential to increase the diagnostic accuracy of soft-tissue radiography of the neck in the identification of adult epiglottitis. METHODS We conducted a prospective, before-and-after blinded study at two tertiary care institutions. A convenience sample of four staff emergency physicians, three otolaryngology...

A simple PS adaptive integral sliding mode controller is designed for the pitch channel linear model of supersonic missile firstly. In order to improve the performance of the proposed method, two improvements also proposed. Finally, a hybrid PISS adaptive control is formed which contains proportion control, integration control, the sign function adn soft function. Also nurmerical simulations ar...
