We study the evolution with pressure P and band filling y of the heat capacity, Hall coefficient, and resistivity at the approach to the T~O Mott-Hubbard metal-insulator transition (MIT) in highly correlated V2 ~03. Under P, the electronic effective mass m diverges at the MIT with a negligible change in carrier concentration n away from half-filling. Conversely, in the doped system m actually d...

[1] Enhancements in F-region electron density and temperature and bottomside Pedersen conductivity caused by soft electron precipitation are shown to enhance the Joule heating per unit mass and the mass density of the thermosphere at F-region altitudes. The results are derived from the coupled magnetosphere-ionosphere-thermosphere model (CMIT) including two types of causally specified soft elec...

Quark and lepton masses in technicolor theories can be enhanced if the high energy, extended technicolor (ETC) interactions play an important role in electroweak symmetry breaking. This happens when the ETC coupling and the technicolor gauge coupling at high energies lie close to a certain critical line. The enhancement has been associated with the existence of composite scalars made mainly of ...

Gastric carcinosarcoma is a rare cancer of adults with poor prognosis compared with other gastric malignancies. To the best of our knowledge, the present report is the first case of gastric carcinosarcoma with chondroblastic differentiation in Iran. A 63-year-old man with epigastric pain was admitted to the surgery department. Abdominopelvic CT-scan showed a hypodense mass lesion in distal gast...

Based on a realistic model for the meson in free space we investigate its medium modiications through rescattering in a hot hadron gas. Within the vector dominance model the corresponding in-medium spectral function is applied to calculate e + e ? spectra in central Pb+Au as measured by the CERES collaboration at CERN-SpS energies; we also compare to results obtained with the assumption of a 'd...

Three different cases of magnetic field reentrant ground states in heavy fermion systems, URhGe, UGe2 and CeRhIn5 recently studied in Grenoble, are discussed. URhGe is a ferromagnetic superconductor with reentrace of superconductivity under magnetic field (H) which is associated to the spin reorientation field. UGe2 is a ferromagnetic superconductor with an enhancement of the upper critical fie...

Graphene oxide was prepared using modified Hummers method. Stable ethylene-glycol nanofluids containing graphene oxide nanosheets were provided. Nd: YAG pulsed laser was applied to prepare reduced nanofluids. Experimental results revealed that thermal conductivity of the nanofluids is increased with increasing the concentration of graphene oxide (GO) in ethylene glycol. The enhancement ratio of...

AIMS Cardiac involvement in sarcoidosis is reported in up to 30% of patients. Left ventricular involvement demonstrated by contrast-enhanced cardiac magnetic resonance has been well validated. We sought to determine the prevalence and distribution of right ventricular late gadolinium enhancement in patients diagnosed with pulmonary sarcoidosis. METHODS AND RESULTS We prospectively evaluated 8...

Accepted 6 September 1995 A nine-year-old girl was admitted to our hospital with difficulty in walking in September 1993. On physical examination there was a solid mass of 10 x 10 cm in the lumbosacral region and the patient was unable to walk or stand. Bilateral deep tendon reflexes of the lower extremities were hypoactive and muscle strength was also decreased. There was hypoesthesia at L4, L...
