In theories with extra dimensions it is well known that the Lorentz invariance of the D = 4 + n-dimensional spacetime is lost due to the compactified nature of the n dimensions leaving invariance only in 4d. In such theories other sources of Lorentz violation may exist associated with the physics that initiated the compactification process at high scales. Here we consider the possibility of cap...

Background: Patients with Trichotillomania (TC) have an irreversible urge to pull their hair.  This self-mutilation behavior is associated with high level of tension before and a sense of gratification and relief after TC. Objective: To investigate the personality characteristics of patients suffering from TC. Method: The study was performed on 43 TC patients and 43 gender and age-matched non-p...

abstract acase of 48-year-old male, hepatitis b cirrhosis , hepatic hydatid cyst, jaundice, fever, chills suffered from severe abdominal pain in the right upper quadrant. he was suffered from acute cholangitis and spontaneous bacterial peritonitis, and received intravenous antibiotics but his condition rapidly deteriorated to sepsis and severe hepatic failure. the presence of dilated common bil...

A natural approach towards powerful machine learning systems is to enable options for additional machine/user interactions, for instance by allowing the system to ask queries about the concept to be learned. This motivates the development and analysis of adequate formal learning models. In the present paper, we investigate two different types of query learning models in the context of learning ...

The four-massless-particle scattering amplitudes are calculated for Witten’s covariant superstring field theory. The picture-changing effect of the Ramond sector propagator and of the three-boson vertex is displayed. The results agree with the first-quantized prescription of Friedan, Martinet and Shenker except for -the four-boson amplitude, where an extra divergent contact term appears. The ad...

We show that a simple account of hadronic high energy total cross-sections and of the observed masses and flavor-gauge-like couplings of the familiar vector mesons is obtained in a hadronic string model suggested by QCD in the limit of a large number of colors. Our picture involves a Minkowski space which in addition to the well established continuous one time and three space dimensions is endo...

The standard picture of viable higher-dimensional theories is that direct manifestations of extra dimensions occur at short distances only, whereas long-distance physics is effectively four-dimensional. We show that this is not necessarily true in models with infinite extra dimensions. As an example, we consider a five-dimensional scenario with three 3-branes in which gravity is five dimensiona...

In a Hamiltonian formalism we study chiral symmetry for lattice Fermions formulated in terms of Shockley surface states bound to a wall in an extra spatial dimension. For hadronic physics this provides a natural scheme for taking quark masses to zero without requiring a precise tuning of parameters. We illustrate the chiral anomaly as a flow of states in this extra dimension. We discuss two alt...
