Auditory hallucinations in anorexia nervosa
2011
The paper describes two case studies of patients with anorexia nervosa who suffer from auditory hallucinations as the only psychotic symptom. A review of the literature regarding clinical cases of anorexic patients with hallucinations is discussed. Hallucinations in anorexic patients are conceptualized according to different theoretical models which point to a dimensional view of eating disorders.

Precision Mass Measurements beyondSn132: Anomalous Behavior of Odd-Even Staggering of Binding Energies
2012
Atomic masses of the neutron-rich isotopes $^{121--128}\mathrm{Cd}$, $^{129,131}\mathrm{In}$, $^{130--135}\mathrm{Sn}$, $^{131--136}\mathrm{Sb}$, and $^{132--140}\mathrm{Te}$ have been measured with high precision (10 ppb) using the Penning-trap mass spectrometer JYFLTRAP. Among these, the masses of four $r$-process nuclei $^{135}\mathrm{Sn}$, $^{136}\mathrm{Sb}$, and $^{139,140}\mathrm{Te}$ were measured for the first time. An empirical neutron pairing gap expressed as the odd-even staggering of isotopic masses shows a strong quenching across $N=82$ for Sn, with a $Z$ dependence that is unexplainable by the current theoretical models.
Competition between intrinsic and extrinsic effects in the quenching of the superconducting state in FeSeTe thin films
2015
We report the first experimental observation of the quenching of the superconducting state in current-voltage characteristics of an iron-based superconductor, namely, in FeSeTe thin films. Based on available theoretical models, our analysis suggests the presence of an intrinsic flux-flow electronic instability along with non-negligible extrinsic thermal effects. The coexistence and competition of these two mechanisms classify the observed instability as halfway between those of low-temperature and of high-temperature superconductors, where thermal effects are respectively largely negligible or predominant.
Hydrodynamic chromatography of macromolecules on small spherical non-porous silica particles
1990
Abstract Non-porous silica spheres with sizes in the range 1.4–2.7 μm were applied as packings for the hydrodynamic chromatography (HDC) of macromolecules. Highly efficient columns, with a reduced plate height below 2, were packed with these small particles. Up to molecular weights of 10 6 the elution behaviour of polystyrenes agreed very well with existing theoretical models. However, for larger polystyrenes the flow-rate exerted an influence on the relative peak positions. The applicability of HDC to rapid separations of soluble macromolecules and inorganic colloids was demonstrated.
Study on New Product Development, by Networking
2015
The paper presents a situation of working in network in order to design or improve a new product. To implement theoretical models and to validate a working algorithm into a virtual research, there was proposed a specific theme from drilling and chamfering tool. The facilities offered by the research centers – database, software - led to rapid selection and configuration solutions, demonstrating achieving research productivity growth and a substantial reduction of times redesign.
Cognitive processes related to problematic pornography use (PPU): A systematic review of experimental studies
2021
Highlights • Some people experience symptoms derived from pornography viewing. • Cognitive processes may be related to the development of Problematic Pornography Use (PPU). • We performed a systematic review of 21 studies exploring cognitive processes related to PPU. • We identified 4 cognitive processes relevant for the development and maintenance of PPU.
Apoyo social de familia, profesorado y amigos, ajuste escolar y bienestar subjetivo en adolescentes peruanos
2021
espanolIntroduccion: La psicologia positiva ha senalado la importancia del bienestar subjetivo de los adolescentes, por ser un precursor del desarrollo positivo de los jovenes. La investigacion resalta la importancia del apoyo social percibido y el ajuste escolar como determinantes del bienestar adolescente. Por ello, este articulo tiene como finalidad analizar las relaciones de la percepcion de apoyo social (de familia, profesorado, amigos) con el bienestar subjetivo de los adolescentes, mediado por su ajuste escolar. Metodo: Participaron 1035 estudiantes peruanos de educacion secundaria, con edades entre 12 y 16 anos. Se probaron dos modelos teoricos con variables latentes, uno con mediac…
Extracting Structured Knowledge From Sensor Data for Hybrid Simulation
2014
Obtaining continuous and detailed monitoring of indoor environments has today become viable, also thanks to the widespread availability of effective and flexible sensing technology; this paves the way for the design of practical Ambient Intelligence systems, and for their actual deployment in real-life contexts, which require advanced functionalities, such as for instance the automatic discovery of the activities carried on by users. Novel issues arise in this context; on one hand, it is important to reliably model the phenomena under observation even though, to this end, it is often necessary to craft a carefully designed prototype in order to test and fine-tune the theoretical models.
Sex-role orientation and memory for gender-related terms: Another uncertain link
1989
Two studies are reported which investigate the relationship between sex-role orientation and memory for gender-related terms. Based on the concept of ‘cognitive schema’, theoretical models have recently been advanced suggesting that the schematic cognitive representation of gender facilitates the recall of words pertinent to gender. One of these models, Markus' self-schema theory, proposes that masculine and feminine sex-typed individuals have a better memory for terms that correspond to their respective self-schemata. In contrast, Bem's gender schema theory implies that sex-typed individuals have a better memory for the category of gender as a whole, i.e. for both masculine and feminine te…
Investigation on the influence of the surface resin rich layer on the thermoelastic signal from different composite laminate lay-ups
2006
This work presents a set of experimental results based on the measured thermoelastic signal from GRP composite coupons adopting different lay-ups. A comparison is made with the thermoelastic signal predicted by two different analytical models: one based on the classical law of the thermoelastic effect for orthotropic materials, and the other based on a novel theory accounting for the presence of a resin layer on the external surface of the composite structure. The composite coupons were designed such to determine a significant difference in the predictions made by the two theoretical models. Experimental results have shown a far better match with the predictions based on the novel theory ac…
