The purpose of this study was to investigate whether the gating of interlimb cutaneous reflexes is altered by holding an earth-referenced handrail during locomotion. In the first experiment, subjects performed locomotor tasks of varying difficulty (level walking, incline walking, and stair climbing) while lightly holding an earth-referenced rail. In the second experiment, the extent of rail con...

Countless children and youth are exposed to gun violence each year--at home, at school, in their communities, or through the media. Gun violence can leave lasting emotional scars on these children. This article reviews research regarding the psychological effects of gun violence on children and youth, and offers suggestions for how parents, school administrators, and mental health workers can m...

OBJECTIVE To estimate the prevalence of gun ownership and methods of gun storage in homes of pediatric patients before and after an educational intervention. DESIGN Before and after trial. SETTING Hospital based, inner city, pediatric primary care practice. PARTICIPANTS Consecutive sample of parents of patients with appointments August to November 1994. INTERVENTION Before the intervent...

Abstract MOS Current-Mode Logic (MCML) is usually used for high-speed applications. However, almost all MCML circuits are realized with dual-rail scheme. The dual-rail logic circuits increase extra area overhead and the complexity of the layout place and route. Moreover, little standard cells of the dualrail logic circuits have been developed for place-and-route tools, such as Cadence Encounter...

The leakage resistance of rail to earth is an important parameter of electrified railways, and it directly affects the characteristics of traction return current and railway signal track circuit. High speed railways mainly adopt the ballastless track in China, whose rail leakage resistance is very different compared to the resistance in the ordinary railway ballast track condition, usually has ...

Title of Thesis: GUN ACCESS AND FEMICIDE: A DIFFERENTIAL IMPACT OF FIREARMS ON INTIMATE KILLINGS Amanda Brown Cross, Master of Arts, 2005 Thesis directed by: Professor Gary LaFree Department of Criminology and Criminal Justice Studies of intimate partner homicide have repeatedly suggested that gun accessibility increases the risk that a confrontation between intimates will end in the death of o...

The effect of the discontinuity of the rail ends and the presence of lower modulus insulation material at the gap to the variations of stresses in the insulated rail joint (IRJ) is presented. A three-dimensional wheel – rail contact model in the finite element framework is used for the analysis. It is shown that the maximum stress occurs in the subsurface of the railhead when the wheel contact ...

An ultra low-power high-speed rail-to-rail buffer amplifier with improved current summing circuit is proposed for LCD source drivers. By placing two complementary differential pairs in parallel, it is possible to obtain a rail-to-rail input stage. Then, a current summing circuit with two embedded comparators is proposed. With the proposed current summing circuit, the output stages will be turne...

A single-stage, sensor less, coil gun was designed to demonstrate the capability to accelerate a ferromagnetic projectile to high velocity. This paper summarize all important steps during coil gun design, such as physical laws of the coil gun, preliminary calculations, the testing device and final product. The electromagnetic FEA model of the capacitor-driven inductance coil gun was constructed...

OBJECTIVE To describe gun shows and assess the impact of increased regulation on characteristics linked to their importance as sources of guns used in crime. DESIGN Cross-sectional, observational. SUBJECTS Data were collected at a structured sample of 28 gun shows in California, which regulates these events and prohibits undocumented private party gun sales; and in Arizona, Nevada, Texas an...
