Reflectivity measurements in uniaxial superconductors: a methodological discussion applied to the case of La(2-x)Sr(x)CuO(4)
Most of the novel superconductors are uniaxial crystals, with metallic planes
() orthogonal to an insulating axis (). Far-infrared measurements of the
reflectivity provide valuable information on their low-energy
electrodynamics, but involve delicate experimental issues. Two of them are a
possible contamination of from the c axis and the
extrapolation of the data to =0, both above and below .
Here we discuss quantitatively these issues with particular regard to
LaSrCuO, one of the most studied high- materials.Comment: 13 pages with 3 Fig
Implementación del modelo C-FaR en empresas emisoras de deuda privada del sector real colombiano
Trabajo de InvestigaciónCon el resultado de investigación se prevé calcular el valor en riesgo del flujo de caja de las empresas del sector real colombiano que emiten deuda privada mas no cotizan en la Bolsa de Valores, con el fin de analizar y observar los posibles cambios en los flujos de dichas empresas. Permitiendo un proceso de análisis más idóneo sobre el comportamiento de los mismos, así como la variación de liquidez del sector en un periodo determinado tras los movimientos que ocurren en el normal comportamiento de la economía.INTRODUCCIÓN

L'arteterapia per i pazienti con cardiopatia congenita: metodologia di intervento psicologico presso il Reparto di cardiologia, cardiochirurgia pediatrica e cardiopatie conge- nite dell'adulto, IRCCS Policlinico San Donato = Art therapy for hospitalised congenital heart disease patients: a method of psychological intervention at the IRCCS Policlinico San Donato Milanese Hopsital
Il presente lavoro si colloca nell\u2019ambito della Psicocardiologia e si propone di indagare un nuovo progetto di intervento presso il reparto di Cardiologia pediatrica e del congenito adulto dell\u2019IRCSS di San Donato Milanese. A partire dalla rilevazione delle numerose problematiche che affliggono il bambino e l\u2019adolescente ospedalizzato, fino ad arrivare al peso che lo stato emotivo del genitore ha sulla buona salute del figlio, \ue8 stato individuato un forte bisogno di \u201cprendersi cura\u201d, oltre il mero \u201ccurare\u201d, ossia un bisogno di attenzione sul versante emotivo oltre che fisico. L'arteterapia pu\uf2 essere una risposta a tale bisogno: recenti studi hanno dimostrato la sua efficacia in ambito ospedaliero, tenendo conto anche della predisposizione maggiore che bambini e adolescenti hanno alla creativit\ue0. Attraverso la somministrazione e l'analisi di 10 disegni di giovani pazienti con cardiopatia congenita ricoverati, si riscontra come questo intervento offra loro la possibilit\ue0 di esprimere paure e sentimenti relativi all\u2019intervento chirurgico e al vissuto di malattia, in una modalit\ue0 pi\uf9 libera ed immediata. Inoltre, la creazione di un prodotto tangibile d\ue0 agli psicologi l\u2019occasione per poter meglio considerare il disagio psicologico dei giovani pazienti e poter quindi attuare interventi di supporto pi\uf9 specifici e mirati ad essi e ai loro genitori. Questo studio si occupa di valutare le percezioni che i genitori hanno di questo nuovo intervento terapeutico proposto presso il reparto di Cardiologia e Cardiochirurgia Pediatrica, confermandone l\u2019utilit\ue0 per gli attori coinvolti nel \u201cprendersi cura\u201d dei giovani pazienti affetti da CHD.The current work is the presentation of a new project at the IRCSS San Donato Milanese University hospital, in the sphere of Psychocardiology. Hospitalised children and adolescents often face psychosocial difficulties and the psychological condition of their parents frequently has an impact on their wellbeing. A strong need to take care, beyond the mere cure, is necessary in the hospital settings - that is a need to pay attention also to psychological aspects apart from the medical ones. Art therapy could be an answer for this need: the literature has outlined its efficacy in hospital, also due to the higher inclination of children and adolescents toward creativity. By providing and analysing the drawings of 10 young patients with congenital heart disease (CHD), this study outlines how the art therapy program gives these patients the opportunity to freely and directly express fears and anxieties about medical procedures and their disease. Moreover, through the creation of a tangible product, psychologists can better evaluate the psychological troubles of young patients and provide them and their parents with more focused and personalized support. This study also focuses on the perception of the utility that parents have of this new therapeutic intervention, offered at the Department of Paediatric Cardiac Surgery, confirming that art therapy is perceived as being effective and is definitely a good instrument in helping to "take care" of children and adolescents suffering from CHD
Sample-Based High-Dimensional Convexity Testing
In the problem of high-dimensional convexity testing, there is an unknown set S in the n-dimensional Euclidean space which is promised to be either convex or c-far from every convex body with respect to the standard multivariate normal distribution. The job of a testing algorithm is then to distinguish between these two cases while making as few inspections of the set S as possible.
In this work we consider sample-based testing algorithms, in which the testing algorithm only has access to labeled samples (x,S(x)) where each x is independently drawn from the normal distribution. We give nearly matching sample complexity upper and lower bounds for both one-sided and two-sided convexity testing algorithms in this framework. For constant c, our results show that the sample complexity of one-sided convexity testing is exponential in n, while for two-sided convexity testing it is exponential in the square root of n
A Note on Mackinawite (so-called Valleriite) from the Kawayama Mine, Japan
Mackinawite, a new species of copper-free iron sulfide mineral given by EVANS et al. (1964), has been described in connection with its paragenesis with some others. On the basis of its microtextures it is deducible that from the original ore solution four types of solid solutions A (rich in FeS), B (rich in ZnS), C (rich in CuFeS2) and D (including all other sulfide minerals such as FeS2, PbS, etc.) might have been fractionated, and mackinawite is related only to the second type. The thermal effects on the specimens have been scrutinized and the results obtained evidently suggest that the mineral in question is reasonably contained in the system of Cu-Fe-S and gets to be immiscible at certain temperatures (l30°C~200°C) far lower than those shown in the preceding literatures.今村外治教授退官記念特集
