Runaway pacemaker results from pacemaker malfunction and is characterized by sudden increases in the stimulus rate above the set upper rate limit of the pacemaker. Here we report the case of a patient with wide QRS complex tachycardia who was admitted to the emergency unit and diagnosed with runaway pacemaker.

Set of experiments has been developed to study existing runaway electrons in "Damavand" tokamak plasma upon characteristics of hard x-ray emissions produced by collision of the runaway electrons with the plasma particles and limiters. As a first step, spatial distribution of hard x-ray emissions on the equatorial plane of the torus was considered. Obtained spectra of hard x-ray emissions for di...

OBJECTIVE The purpose of this study was to investigate the prevalence of food insecurity and factors related to it among homeless and runaway adolescents. DESIGN Computer-assisted personal interviews were conducted with homeless and runaway adolescents directly on the streets and in shelters. SETTING Interviews were conducted in eight Midwest cities: Des Moines, Cedar Rapids, Iowa City, Kan...

Specific recognition of pathogens is mediated by plant disease resistance (R) genes and translated into a successful defense response. The extent of associated hypersensitive cell death varies from none to an area encompassing cells surrounding an infection site, depending on the R gene activated. We constructed double mutants in Arabidopsis between positive regulators of R function and a negat...

Runaway stars ejected from the Galactic disk populate the halo of the Milky Way. To predict the spatial and kinematic properties of runaways, we inject stars into a Galactic potential, compute their trajectories through the Galaxy, and derive simulated catalogs for comparison with observations. Runaways have a flattened spatial distribution, with higher velocity stars at Galactic latitudes less...

Anti-runaway prevention of rolling stocks at a railway station is essential in railway safety management. The traditional track skates for anti-runaway prevention of rolling stocks have some disadvantages since they are operated and monitored completely manually. This paper describes an anti-runaway prevention system (ARPS) based on intelligent track skates equipped with sensors and real-time m...

The evolution of young compact star clusters is studied using N -body simulations in which both stellar evolution and physical collisions between stars are taken into account. The initial conditions are chosen to represent R 136, a compact star cluster in the 30Doradus region of the Large Magellanic Cloud. The present runs do not include the effects of primordial binaries. We find that physical...

Hydraulic turbines exhibit total load rejection during operation because of high fluctuations in the grid parameters. The generator reaches no-load instantly. Consequently, the turbine runner accelerates to high speed, runaway speed, in seconds. Under common conditions, stable runaway is only reached if after a load rejection, the control and protection mechanisms both fail and the guide vanes ...

LSD1 was defined as a negative regulator of plant cell death and basal disease resistance based on its null mutant phenotypes. We addressed the relationship between lsd1-mediated runaway cell death and signaling components required for systemic acquired resistance (SAR), namely salicylic acid (SA) accumulation and NIM1/NPR1. We present two important findings. First, SA accumulation and NIM1/NPR...
