New n-type molecular semiconductor–doped insulator (MSDI) heterojunctions combining a triphenodioxazine (TPDO) and the lutetium bisphthalocyanine (Lu…
2018
International audience; Molecular semiconductor–doped insulator (MSDI) heterojunctions were designed using a new family of sublayers, namely triphenodioxazines (TPDO). The device obtained by combining the tetracyano triphenodioxazine bearing two triisopropylsilylethynyl moieties as a sublayer with the lutetium bisphthalocyanine (LuPc2) as a top layer showed a nonlinear current–voltage characteristic independent of the sign of the polarization, which is the signature of MSDI heterojunctions. Thus, a TPDO was used in a chemical sensor for the first time. Despite LuPc2 being the only material exposed to the atmosphere, the positive response of the device under ammonia revealed the key role pla…
Social comparison, coping and depression in people with spinal cord injury
2006
The present study among 70 people with spinal cord injury examined the prevalence and correlates of identification (seeing others as a potential future) and contrast (seeing others in competitive terms) in social comparison as related to coping and depression. The most prevalent social comparison strategy was downward contrast (a positive response to seeing others who were worse-off), followed by upward identification (a positive response to perceiving better-off others as a potential future), downward identification (a negative response to perceiving worse-off others as a potential future), and upward contrast (a negative response to seeing others who were better-off). Those with less seve…
Analysis of the Modifications in the Spectral and Morphologic Regularity during Ventricular Fibrillation Produced by Physical Exercise and the Use of…
2015
Chronic physical exercise modifies cardiac activity improving response to malignant arrhythmia and, specifically, ventricular fibrillation (VF). Drug administration as glibenclamide, responsible for K + ATP channel blocking, is also generating a positive response against fibrillation.
Cognitive Structuring and Its Cognitive-Motivational Determinants as an Explanatory Framework of the Fear-Then-Relief Social Influence Strategy
2017
According to the fear-then-relief technique of social influence, people who experience anxiety whose source is abruptly withdrawn usually respond positively to various requests and commands addressed to them. This effect is usually explained by the fact that fear invokes a specific program of action, and that when the source of this emotion is suddenly and unexpectedly removed, the program is no longer operative, but the person has not yet invoked a new program. This specific state of disorientation makes compliance more likely. In this paper, an alternative explanation of the fear-then-relief effect is offered. It is assumed that the rapid change of emotions is associated with feelings of …
Event‐related brain potentials to change in rapidly presented acoustic stimuli in newborns
1997
Event-related brain potentials of 28 newborns to pitch change were studied during quiet sleep under stimulus conditions that typically elicit mismatch negativity in adults. Rarely occurring deviant tones of 1100 Hz (probability 12%) were embedded among repeated standard tones of 1000 Hz in an oddball-sequence with an interstimulus interval of 425 ms. Two control conditions were also employed: In the first, the 1100-Hz stimulus was presented alone without the intervening standard stimuli, and in the second the deviant stimulus had a pitch of 1300 Hz. In all conditions the infrequent stimulus elicited in most newborns a slow positive deflection peaking at a latency of 250-350 ms. The response…
