Mood congruence effect in explicit and implicit memory tasks: a comparison between depressed patients, schizophrenic patients and controls
1993
Summary This study investigates mood congruence effect in explicit and implicit memory tasks in 23 inpatients fulfilling DSM-III-R criteria for major depressive disorder. Performances were compared to those of 15 in- or outpatients fulfilling DSM-III-R criteria for schizophrenia, and 37 normal subjects serving as euthymics controls. All subjects were submitted to a standard cued recall test and to a word stem completion test devised to assess the effect of the initial presentation without the explicit retrieval of the words being necessary. The material used for these two tasks consisted of emotionally negative and positive words. The results show a mood congruence effect in the ```implicit…

X-ray fluorescence analysis by the fundamental parameters method without explicit knowledge of the excitation beam spectrum
2000
The results of analyses carried out with the fundamental parameters method without explicit knowledge of the beam exciting the sample are presented. The excitation beam is described by means of the fluorescence produced by a set of thick or thin targets of pure chemical elements. The results are compared with those obtained by using a semi-empirical model and an adjusted spectrum model, all sets of results being in turn compared with the actual chemical composition of the samples. It is concluded that the description of the excitation beam by means of the fluorescence produced on targets of pure elements is suitable for use with the fundamental parameters method.

Occupancy, density, and activity patterns of a Critically Endangered leopard population on the Kawthoolei‐Thailand border
2023
Large carnivores have been largely extirpated from Southeast Asia due to deforestation, habitat fragmentation, and poaching. Estimating the density of endangered carnivore populations, and identifying relationships between species occupancy and both environmental and anthropogenic factors, is essential for effective conservation planning. Recently, the IUCN conservation status of the Indochinese leopard (Panthera pardus delacouri) was upgraded to "Critically Endangered. " We surveyed Kweekoh Wildlife Sanctuary in Kawthoolei, an area administered by the Karen ethnic group in eastern Myanmar, to quantify (1) leopard population density using spatially explicit mark-resight (SMR) models, (2) le…
INTUITION OF FAMILY ENTREPRENEURS: AN EXPLORATORY STUDY OF PERCEPTIONS AND EXPERIENCES
2005
Many business problems do not appear in ideal conditions. Sometimes decisions have to be made very quickly, or there is no explicit knowledge regarding a problem, or there is neither enough time nor enough information. Therefore, entrepreneurs are not always equipped to make the necessary decision or to solve the problem. A successful entrepreneur needs to rely more often on intuition in making decisions and in solving problems. Intuition can be considered, for example, as a sudden awareness of knowledge. Using this type of knowledge, a person knows facts or relations, but without knowing why.Previous studies have described the nature of intuition and they have also addressed the intuitive …
Implicit and explicit syntactic knowledge and reading in pre-adolescents
1999
This aim of this paper is to analyse the links between syntactic awareness and reading, in its recoding and comprehension aspects, in pre-adolescent readers. The study, conducted with 83 sixth grade pupils, examined the relation between (1) seven syntactic and morpho-syntactic tasks (repetition, judgment, correction, localization, explanation, replication and identification) and (2) several indicators of recoding and comprehension in reading. Regression analyses revealed differential contributions as a function of syntactic task, type of agrammaticality, and the aspect of reading tested, after we had controlled for the influence of reasoning, memory, and linguistic competences.

Gravity triggered neutrino condensates
2010
In this work we use the Schwinger-Dyson equations to study the possibility that an enhanced gravitational attraction triggers the formation of a right-handed neutrino condensate, inducing dynamical symmetry breaking and generating a Majorana mass for the right-handed neutrino at a scale appropriate for the seesaw mechanism. The composite field formed by the condensate phase could drive an early epoch of inflation. We find that to the lowest order, the theory does not allow dynamical symmetry breaking. Nevertheless, thanks to the large number of matter fields in the model, the suppression by additional powers in G of higher order terms can be compensated, boosting them up to their lowest ord…
Unidirectional Magnon-Driven Domain Wall Motion Due to the Interfacial Dzyaloshinskii-Moriya Interaction
2018
We demonstrate a unidirectional motion of a quasiparticle without an explicit symmetry breaking along the space-time coordinate of the particle motion. This counterintuitive behavior originates from a combined action of two intrinsic asymmetries in the other two directions. We realize this idea with the magnon-driven motion of a magnetic domain wall in thin films with interfacial asymmetry. Contrary to previous studies, the domain wall moves along the same direction regardless of the magnon-flow direction. Our general symmetry analysis and numerical simulation reveal that the odd order contributions from the interfacial asymmetry is unidirectional, which is dominant over bidirectional contr…
General Hartree–Fock method and symmetry breaking in quantum dots
2010
Interaction and correlation effects in quantum dots play a fundamental role in defining both their equilibrium and transport properties. Numerical methods are commonly employed to study such systems. In this paper we present a two-step approach in which a Hartree-Fock method, with explicit symmetry breaking, is followed by a projection technique for symmetry restoration. Three different Hartree-Fock implementations, with an increasing degree of symmetry breaking, are introduced and applied to the study of interacting planar dots with N = 3 and 6, electrons in the presence of a perpendicular magnetic field. In addition to the restricted and unrestricted techniques already employed for quantu…
Pseudobosons, Riesz bases, and coherent states
2010
In a recent paper, Trifonov suggested a possible explicit model of a PT-symmetric system based on a modification of the canonical commutation relation. Although being rather intriguing, in his treatment many mathematical aspects of the model have just been neglected, making most of the results of that paper purely formal. For this reason we are re-considering the same model and we repeat and extend the same construction paying particular attention to all the subtle mathematical points. From our analysis the crucial role of Riesz bases clearly emerges. We also consider coherent states associated to the model.
