RESONANT ACTIVATION AND NOISE ENHANCED STABILITY IN JOSEPHSON JUNCTIONS

2005

We investigate the interplay of two noise-induced effects on the temporal characteristics of short overdamped Josephson junctions in the presence of a periodic driving. We find that: (i) the mean life time of superconductive state has a minimum as a function of driving frequency, and near the minimum it actually does not depend on the noise intensity (resonant activation phenomenon); (ii) the noise enhanced stability phenomenon increases the switching time from superconductive to the resistive state. As a consequence there is a suitable frequency range of clock pulses, at which the noise has a minimal effect on pulse propagation in RSFQ electronic devices.

Colorectal Cancer Stem Cells: From the Crypt to the Clinic

2014

Since their first discovery, investigations of colorectal cancer stem cells (CSCs) have revealed some unexpected properties, including a high degree of heterogeneity and plasticity. By exploiting a combination of genetic, epigenetic, and microenvironmental factors, colorectal CSCs metastasize, resist chemotherapy, and continually adapt to a changing microenvironment, representing a formidable challenge to cancer eradication. Here, we review the current understanding of colorectal CSCs, including their origin, relationship to stem cells of the intestine, phenotypic characterization, and underlying regulatory mechanisms. We also discuss limitations to current preclinical models of colorectal …

I sette doni dello Spirito Santo nella poesia religiosa tedesca del XII secolo

2016

The essay deals with the theme of the Seven Gifts of the Holy Spirit in a group of early Middle High German works dating from the XII century: a Commentary on the Our Father, the Siebenzahl (or De vii Sigillis), Priester Arnolt’s Loblied auf den heiligen Geist and a passage of Frau Ava’s Leben Jesu devoted to the Gifts of the Holy Spirit. The analysis focuses on the connections between these texts and the devotional literature of medieval Germany, with particular regards to the numerological philosophy, and above all to the symbolism of number “seven”. Attention will be paid to the didactic and catechetic role of the the Seven Gifts of the Holy Spirits within these works, highlighting a num…

Muslim Martyrs and Pagan Vampires

2005

In December 2000 the government of Kano State in Muslim northern Nigeria reintroduced shari’a and established a new board for film and video censorship charged with the responsibility to “sanitize” the video industry and enforce the compliance of video films with moral standards of Islam. Stakeholders of the industry took up the challenge and responded by inserting religious issues into their narratives, and by adding a new feature genre focusing on conversion to Islam. This genre is characterized by violent Muslim/pagan encounters, usually set in a mythical past, culminating in the conversion of the pagans. This article will first outline northern Nigerian video culture and then go on to e…

Research Letter: is neuroticism a risk factor for postpartum depression?

2012

Although the relationship between personality and depressive illness is complex (Shea, 2005), there is empirical evidence that some personality features such as neuroticism, harm avoidance, introversion, dependency, self-criticism or perfectionism are related to depressive illness risk (Gunderson et al. 1999). Moreover, personality traits, especially neuroticism, may explain the increased prevalence of depression among females (Goodwin & Gotlib, 2004). Few studies have explored neuroticism, extraversion and psychoticism as risk factors for depression after an event as stressful as childbirth. Pitt (1968) was the first author to report high scores on neuroticism and low scores on extraversio…

Pot la psicologia rescatar-se a si mateixa?. Incentius, biaix i replicabilitat

2018

En els últims anys la Psicologia està patint internament i externa una crisi important de credibilitat, a la qual tampoc han estat alienes altres ciències, com ara la Medicina o la Biologia. Diversos projectes de ciència de col·laboració suggereixen que una gran part dels resultats de la investigació són difícils de reproduir. Això ve acompanyat d’un conjunt de simulacions i anàlisis quantitatives que situen la quantitat de falsos positius per damunt del 50% del total de dades publicades en la literatura psicològica actual. En aquest breu treball realitzarem una anàlisi actualitzada de la situació i intentarem identificar les causes psicològiques que hi han contribuït. Entre aquestes destaq…

The Narcissistic Personality Inventory 8: Validation of a Brief Measure of Narcissistic Personality

2020

The present study was conducted with the aim of constructing and validating a short form of the Narcissistic Personality Inventory (NPI). The NPI is the most widely-applied measure for the assessment of narcissistic personality traits and, therefore, it is of great relevance for many research questions in personality and social psychology. To develop the short scale, we first found the optimal eight-item solution among all valid combinations of the NPI-15 items in an exploratory subsample (n = 1,165) of our complete representative sample of the German general population. We then validated this model in a confirmatory subsample (n = 1,126). Additionally, we examined its invariance across age…

Modeling the escalation/de-escalation of response operation levels in disaster response networks using hierarchical Colored Petri Nets (CPN) approach

2018

In emergency situations, the first responders need to act promptly to situations, while the disaster management authorities' response might not be at the same speed. Delays by disaster management authorities had a direct impact on response operations led response teams to the shift away from command and control structures to net-centric ones. This paper is part of a study to examine patterns of emerging organizational relations and coordination structures in disaster response operations. Understanding coordination patterns in disaster chaos can help to integrate those patterns in the planning and execution in the modern disaster management operations. We use dynamic modeling methods to anal…
