Within the framework of the e ective eld theory, we examine the phase transitions of the spin1 2 Ising lm in a transverse eld. We study the critical temperature of the lm as a function of the exchange interactions, the transverse eld and the lm thickness. We nd that, if the ratio of the surface exchange interactions to the bulk ones R= Js=J is smaller than a critical value Rc, the critical temp...

The transverse-axial tubular system (TATS) of cardiac ventricular myocytes is a complex network of tubules that arises as invaginations of the surface membrane; it appears to form a specialised region of cell membrane that is particularly important for excitation-contraction coupling. However, much remains unknown about the structure and role of the TATS. In this brief review we use experimenta...

Although conduction velocity in cardiac tissue is dependent on fiber orientation, the influence of commonly used antiarrhythmic agents on conduction longitudinal and transverse to such fibers is unknown. We evaluated the effects of procainamide on conduction velocity and intracellular potentials in vitro during conduction longitudinal and transverse to fiber orientation in epicardial strips obt...

Energy intensity, Ie (kWh/m3) is the most popular indicator when characterizing energy requirements of water cycle, due to its direct and easy interpretation. In pressurized transport systems, referred an appropriate physical framework (such as a single pipeline), it assesses efficiency process. However, in complex urban networks, only provides basic notion needs system. The aim this paper defi...

A recently proposed and fundamentally different Cenozoic geology glacial history paradigm (new paradigm) is used to explain previously reported other anomalous Monongahela River drainage basin system evidence (observable on detailed topographic maps in the form of barbed tributaries, asymmetric tributary basins, large abandoned meander cutoffs, poorly explained transverse drainages drainages). ...

We describe a case of acute transverse myelitis after the administration of the recombinant form of hepatitis B vaccine. Abnormal enhancement of MR imaging accompanied residual neurologic deficit.

We investigate the dynamical possibility for the formation of a transient new coherent condition of matter in high–energy hadronic collisions. The coherent bosonic amplitude is characterized by a non–zero momentum and is sustained by P–wave interactions of quasi–pions in a dense fermionic medium. We make quantitative estimates of several essential properties: the condensate momentum and the fer...

[1] The Great Salt Lake is a terminal lake whose level is determined by the balance between inflows and outflows. We examine the causes for multimodality in the distributions of lake level and hence volume and area that have previously been examined from a system dynamics perspective. We focus on the role of bathymetry in the dynamics of this system and show that some of the modes that are obse...

The technique of extracellular space tracing with horseradish peroxidase is adapted for labeling the transverse tubular system (T system) in rat heart. In rat ventricular muscle the T system shows extensive branching and remarkable tortuosity. The T system can only be defined operationally, since it does not display specific morphological features throughout its entire structure. Owing to branc...

We study the vortex phase diagram in untwinned YBCO crystals with columnar defects. These randomly distributed defects are expected to induce a "Bose glass" phase of localized vortices exhibiting a vanishing resistance and Meissner effect for magnetic fields H( perpendicular) transverse to the columns. We directly observe the transverse Meissner effect using a Hall probe array. As predicted, th...
