We present detailed analyses of the vacuum structure of the scalar potential in a supersymmetric Mass Varying Neutrinos model. The observed dark energy density is identified with false vacuum energy and the dark energy scale of order (10eV) is understood by gravitationally suppressed supersymmetry breaking scale, F (TeV)/MPl, in the model. The vacuum expectation values of sneutrinos should be t...

background: in oil refinery plants, shift working is inevitable . shift work is associated with depression; therefore this prospective study was carried out in tehran shahid tondguyan oil refinery in order to determine the prevalence of depression in shift workers and to assess the effects of associated factors with depression among shift workers. in the present study, the shifting work system ...

Search behavior is often used as a proxy for foraging effort within studies of animal movement, despite it being only one part of the foraging process, which also includes prey capture. While methods for validating prey capture exist, many studies rely solely on behavioral annotation of animal movement data to identify search and infer prey capture attempts. However, the degree to which search ...

In the context of interactive, virtual experiences, the use of personality models to maintain consistent character behaviour is becoming more widespread in both industry and academia. Most current techniques, however, are limited in one of three ways: either they overly restrict user actions, have a high cost for creating varied content, or rely on a representation that prohibits conveying comp...

OBJECTIVES We propose an automatic breast mass detection algorithm in three-dimensional (3D) ultrasound (US) images using the Hough transform technique. METHODS One hundred twenty-five cropped images containing 68 benign and 60 malignant masses are acquired with clinical diagnosis by an experienced radiologist. The 3D US images are masked, subsampled, contrast-adjusted, and median-filtered as...

Elevated concentrations of progesterone receptor, a sensitive indicator of estrogen responsiveness, have been measured in this study during early serial transplan tation of estrogen-induced renal adenocarcinoma tissue in hamsters. A new approach of tumor transplantation beneath the renal capsule has been used. Fragments of primary tumor tissue transplanted subpannicularly in es trogen-treated h...

On the basis of the Kerr spinning particle, we show that the mass renormalization is perfectly performed by gravity for an arbitrary distribution of source matter. A smooth regularization of the Kerr-Newman solution is considered, leading to a source in the form of a rotating bag filled by a false vacuum. It is shown that gravity controls the phase transition to an AdS or dS false vacuum state ...
