Propagation and interaction of ultrashort electromagnetic pulses in nonlinear media with a quadratic-cubic nonlinearity

, 2000
Propagation of extremely short unipolar pulses of electromagnetic field ("videopulses") is considered in the framework of a model in which the material medium is represented by anharmonic oscillators (approximating bound electrons) with quadratic and ...

Clinical predictors of the defibrillation threshold with the unipolar implantable defibrillation system

Journal of the American College of Cardiology, 1995
The purpose of this study was to determine the relation between clinical variables and the defibrillation threshold by using a standardized testing protocol and a uniform implantable defibrillator system.Past studied have not revealed useful correlations between clinical variables and the energy required to terminate ventricular fibrillation.

From unipolarity to bipolarity: Systemic transformation and the emergence of post-unipolar international politics

Journal of Regional Security
With the decline of U.S. unipolarity and the rise of Sino-American bipolarity, this article explores a conceptualization of systemic transformation in international politics and its implications for outcomes in state behaviors during the transition.

Bright Light as a Personalized Precision Treatment of Mood Disorders

Frontiers in Psychiatry, 2019
Background: The use of light for its antidepressant action dates back to the beginnings of civilization. Three decades ago, the use of bright-light therapy (BLT) for treating Seasonal Affective Disorder (SAD) was officially proposed.

Maternal Interaction Style in Affective Disordered, Physically Ill, and Normal Women

, 1993
Affective style (AS) and communication deviance (CD) have been suggested as markers of dysfunctional family environments that may be associated with psychiatric illness. Studies have focused mainly on parental responses during family interactions when an

The roots of coronal structure in the Sun's surface [PDF]

, 1994
We have compared the structures seen on X-ray images obtained by a flight of the NIXT sounding rocket payload on July 11, 1991 with near-simultaneous photospheric and chromospheric structures and magnetic fields observed at Big Bear.

From unipolarity to multipolarity: toward global order, or disorder?

Australian and New Zealand Journal of European Studies
Multipolarity is often viewed as the alternative to a hegemonic international political order managed since 1991 by the United States. With the inauguration of President Donald Trump in January 2025, the unipolar order has not been abandoned even if ...

SiOx-based resistive switching memory integrated in nanopillar structure fabricated by nanosphere lithography [PDF]

, 2014
textA highly compact, one diode-one resistor (1D-1R) SiOx-based resistive switching memory device with nano-pillar architecture has been achieved for the first time using nano-sphere lithography. The average nano-pillar height and diameter are 1.3 μm and
