Scanning Hall probe microscopy (SHPM) has been used to study vortex structures in thin epitaxial films of the superconductor MgB2. Unusual vortex patterns observed in MgB2 single crystals have previously been attributed to a competition between short-range repulsive and long-range attractive vortex-vortex interactions in this two band superconductor; the type 1.5 superconductivity scenario. Our...

We consider the 3+1 visible sector to live on a Hanany-Witten D-brane construction in type IIA string theory. The messenger sector consists of stretched strings from the visible brane to a hidden D6-brane in the extra spatial dimensions. In the open string channel supersymmetry is broken by gauge mediation while in the closed string channel supersymmetry is broken by gravity mediation. Hence, w...

We study the physics of spontaneously broken family symmetries acting on the third generation. Massless familons φ associated with such broken symmetries are motivated especially by cosmological scenarios with decaying tau neutrinos. We first note that, in marked contrast with the case for the first two generations, constraints on third generation familon couplings are poor, and are, in fact, n...

Abstract We revisit the mass-size relation of molecular cloud structures based on column density map Cygnus-X complex. extract 135 peaks in and analyze distributions around these peaks. The averaged profiles, N(R) , all can be well fitted with broken power-laws, which are described by an inner power-law index n outer m radius R TP N at transition point. then explore M-R different samples varyin...

Image-guided surgery can be broken down into two broad categories: frame-based guidance and frameless guidance. In order to reduce both the invasive nature of stereotactic guidance and the cost in equipment and time, we have developed a new guidance technique based on rapid prototyping (RP) technology. This new system first builds a computer model of the patient anatomy and then fabricates a ph...

A simple thermodynamic analysis suggests that oil can spontaneously displace water from coal’s surface if the coal particle has a water contact angle greater than 90°. However, the clean coal products obtained from laboratory-scale dewatering-by-displacement (DbD) test work assayed moistures substantially higher than expected. These high moisture contents were attributed to the formation of wat...

a “cocktail”of several probe drugs is often used to evaluate metabolic activity of multiple cytochrome p450 enzymes in one session. some interactions among probe drugs can appear and may impact the rate of biotransformation of other ones. our presented work was to aim on the influence of bupropion on rat cytochrome p450-mediated metabolism of tolbutamide. the biotransformation rates of tolbutam...

We analyze the thermal phases of a non critical holographic model of QCD. The model is based on a six dimensional background of Nc non extremal D4 branes wrapping a spacial circle of radius R and the compactified Euclidean time direction of radius β = 1/T . We place in this background stacks of Nf D4 and anti-D4 flavor probe branes with a separation distance L at large radial direction. The ana...
