Electronic structure and electron correlations of the Hubbard model on β-Mn lattice have been investigated basis momentum dependent local ansatz wavefunction method. It is found that electrons are significantly correlated as compared with those face centered cubic (fcc) body (bcc) lattices; correlation energy gain largest among β-Mn, fcc, bcc structures, charge fluctuations show a significant s...

Corticosteroid-induced reduction in contrast enhancement on radiographic imaging is most commonly associated with lymphoma but has been reported in other entities, including glioma. This finding may represent a diagnostic dilemma. Concern that steroid-induced cytotoxicity obscures histological diagnosis of suspected lymphoma may lead to postponement of a biopsy. If glioma is not considered in t...

BACKGROUND Mammography screening is a cost-efficient modality with high sensitivity for detecting impalpable cancer with microcalcifications, and results in reduced mortality rates. However, the probability of finding microcalcifications without associated cancerous masses varies. We retrospectively evaluated the diagnosis and cancer probability of the non-mass screened microcalcifications by d...

PURPOSE We aimed to evaluate the imaging features of breast lymphoma using magnetic resonance imaging (MRI). METHODS This retrospective study consisted of seven patients with pathologically confirmed breast lymphoma. The breast lymphomas were primary in six patients and secondary in one patient. All patients underwent preoperative dynamic contrast-enhanced MRI and one underwent additional dif...

We investigated the electron–phonon coupling (EPC), in the vicinity of the Fermi level, for the surface-weighted states of Mo(112) from high resolution angle-resolved photoemission data taken parallel to the surface corrugation (i.e. 〈1̄1̄1〉). The surface-weighted bandwidth may be discussed in terms of electron–electron interactions, electron impurity scattering and electron–phonon coupling and e...

We describe the CT and MR findings of primary leiomyosarcoma of the liver and review the radiological findings of the previous reports of this disease. A 35-year-old woman presented with discomfort in the right upper quadrant of the abdomen. On contrast-enhanced CT, a well circumscribed and lobulated, homogeneously hypoattenuating solid mass with slight peripheral enhancement was identified in ...

A 41-year-old man presented with bilateral leg numbness and paraparesis for 3 months. MRI showed a circumferential long epidural mass extending from T2 to T4 level (figure 1). Histologic examination demonstrated dense fibrous tissue with inflammatory infiltrate (figure 2). By exclusion of trauma, infectious diseases, and autoimmune diseases, idiopathic hypertrophic spinal pachymeningitis (IHSP)...

PURPOSE To describe the MR findings in six patients with recurrent cerebral astrocytomas before, immediately after, and 3 months after local immunotherapy with tumor-infiltrating lymphocytes and interleukin-2. METHODS Contrast-enhanced MR studies were obtained in six patients (three with anaplastic astrocytoma and three with glioblastoma multiforme) at the time of tumor recurrence, after a se...

We show that the Galactic Cosmic Ray source (GCRS) composition is best described in terms of (i) a general enhancement of the refractory elements relative to the volatile ones, and (ii) among the volatile elements, an enhancement of the heavier elements relative to the lighter ones; this mass dependence most likely reflects a mass-to-charge (A/Q) dependence of the acceleration efficiency; among...

A complete theoretical presentation of the Continuum-mechanical, Anisotropic Flow model, based on an anisotropic Flow Enhancement factor (CAFFE model) is given. The CAFFE model is an application of the theory of mixtures with continuous diversity for the case of large polar ice masses in which induced anisotropy occurs. The anisotropic response of the polycrystalline ice is described by a gener...
