OBJECTIVES This report characterizes the paradoxical sinus deceleration occasionally observed during dobutamine stress testing and determines its relation to myocardial ischemia. BACKGROUND Dobutamine stress echocardiography is widely accepted as a noninvasive tool for evaluating coronary artery disease. With infusion of dobutamine, there is typically a dose-dependent increase in heart rate. ...

In this Letter we study how fast the energy density of a quantum gas can increase in time, when interatomic interaction characterized by $s$-wave scattering length ${a}_{s}$ is increased from zero with arbitrary time dependence. We show that, at short most as $\sqrt{t}$, which be achieved dependence also proportional to and especially, universal maximum growth rate reached varies $2\sqrt{\ensur...

A system of identical cars on a single-lane road is treated as a microcanonical and canonical ensemble. Behaviour of the cars is characterized by the probability of car velocity as a function of distance and velocity of the car ahead. The calculations a performed on a discrete 1D lattice with discrete car velocities. Probability of total velocity of a group of cars as a function of density is c...

Methods for the production of cold atomic and molecular samples relying on the deceleration of pulsed supersonic beams are described and a review of the corresponding literature is presented. These methods include multistage Stark deceleration, multistage Zeeman deceleration, and Rydberg-Stark deceleration. Recent applications of the cold samples produced with these techniques are summarized.

BACKGROUND It has been suggested that gender differences in the performance of athletic maneuvers is a contributory factor with respect to the disproportionate incidence of non-contact anterior cruciate ligament injury in female athletes. The purpose of this study was to evaluate gender differences in knee joint kinematics, kinetics and muscle activation during a side-step cutting. METHODS Th...

We developed a maximum profit inventory model with generalized deterioration rate where the selling is dependent on level that an extension of two published papers. A complete solution structure provided to decide optimal reasonable conditions supported by numerical examples, and then we prove independent demand pattern. Numerical examples are illustrate our findings. In previously paper, three...

In mammals, somatic growth is rapid in early postnatal life but decelerates with age and eventually halts, thus determining the adult body size of the species. This growth deceleration, which reflects declining proliferation, occurs simultaneously in multiple organs yet appears not to be coordinated by a systemic mechanism. We, therefore, hypothesized that growth deceleration results from a gro...

One of the major resources in regions is financial which are usually translated into Regional Revenue and Expenditure Budget (APBD). In its management, it creates uncertainty about fulfillment human rights regional management. This because one them regulation causes budget allocation for issue Economic, Social Cultural Rights to be very inadequate. this study, authors used a normative research ...

Hydrogen and deuterium Rydberg atoms, initially moving at velocities of 600 m/s and 560 m/s, respectively, in pulsed supersonic beams, have been decelerated and electrostatically trapped following adiabatic 90◦ deflection from their initial axis of propagation to minimise collisions with the trailing edge of the gas pulses. The time evolution of the potential energy surfaces, over which the ato...
