Re-analysis of fatigue data for welded joints using the notch stress approach
2010
Abstract Experimental fatigue data for welded joints have been collected and subjected to re-analysis using the notch stress approach according to IIW recommendations. This leads to an overview regarding the reliability of the approach, based on a large number of results (767 specimens). Evidently, there are some limitations in the approach regarding mild notch joints, such as butt joints, which can be assessed non-conservatively. In order to alleviate this problem, an increased minimum notch factor of Kw ⩾ 2.0 is suggested instead of the current recommendation of Kw ⩾ 1.6. The data for most fillet-welded joints agree quite well with the FAT 225 curve; however a reduction to FAT 200 is sugg…
Familiares de personas afectadas por COVID-19: psicopatología, estrés, percepción de amenaza y apoyo social
2021
La nueva enfermedad conocida como COVID-19 ha sacudido nuestras vidas y ha supuesto una verdadera amenaza no solo para las personas que la padecen, sino también para sus familiares. Objetivo: Evaluar los factores de riesgo y protección en los familiares de personas afectadas por COVID-19. Método: Una vez firmado el consentimiento informado, los participantes (n=50) completaron una entrevista sociodemográfica y se evaluó su grado de malestar emocional (SCL-90-R), estrés (PSS-14), percepción de amenaza (BIP-Q5) y apoyo social (MOS-SSS). Resultados: Los familiares que participaron presentaron malestar emocional, estrés, sensación de amenaza y apoyo social moderados. Conclusiones: Nuestro estud…
MLOG: a strongly typed confluent functional language with logical variables
1994
Poirriez, V., MLOG: a strongly typed confluent functional language with logical variables, Theoretical Computer Science 122 (1994) 201-223. A new programming language called MLOG is introduced. MLOG is a conservative extension of ML with logical variables. To validate our concepts, a compiler named CAML Light FLU0 was implemented. Numerous examples are presented to illustrate the possibilities of MLOG. The pattern matching of ML is kept for X-calculus bindings and an unification primitive is introduced for the logical variables bindings. A suspension mechanism allows cohabitation of pattern-matching and logical variables, Although the evaluation strategy for the application is fixed, the or…
Diagnostic tools for GAMLSS fitted objects
2015
In the last years GAMLSS models were applied in many research fields representing a good solution to analyze data with huge variabilty. In this paper we propose a new approach to diagnostics in GAMLSS as an alternative to classical worm plot. An application will be shown where the class of GAMLSS is applied in order to detect the presence of liver fibrosis as a function of patients risk factors.
Separate regression modelling of the Gaussian and Exponential components of an EMG response from respiratory physiology.
2014
If Y1 \sim N(\mu ;\sigma^2) and Y2 \sim Exp(\nu), with Y1 independent of Y2, then their sum Y = Y1 +Y2 follows an Exponentially Modified Gaussian (EMG) distribution. In many applications it is of interest to model the two components separately, in order to investigate their (possibly) different important predictors. We show how this can be done through a GAMLSS with EMG response, and apply this separate regression modelling strategy to a dataset on lung function variables from the SAPALDIA cohort study.
The Use of GAMLSS Framework for a Non-Stationary Frequency Analysis of Annual Runoff Data over a Mediterranean Area
2022
Climate change affects all the components of the hydrological cycle. Starting from precipitation distribution, climate alterations have direct effects on both surface water and groundwater in terms of their quantity and quality. These effects lead to modifications in water availability for agriculture, ecology and other social uses. Change in rainfall patterns also affects the runoff of natural rivers. For this reason, studying runoff data according to classical hydrological approaches, i.e., statistical inference methods that exploit stationary probability distributions, might result in missing important information relevant to climate change. From this point of view, a new approach has to…
A flexible approach for modelling a proportion response variable: Loss given default
2016
Loss given default (LGD) is a proportion of a credit exposure that is lost if the obligor defaults on a loan. Response variable LGD contains values between 0 and 1 including both 0 and 1, where 0 means that the balance is fully recovered while 1 means total loss of exposure at default. This article addresses two alternative semi parametric approaches for modelling loss given default, which is measured on the interval [0,1]. The class of models are very flexible and can accommodate skewness and bimodal characteristics of LGD data. The dependence of the predictors of each of the parameters (of the proposed model distribution for LGD) on explanatory variables can be additive P-splines, regress…
Tommaso Salvini 1860: Fortinbras come Garibaldi al Teatro dei Fiorentini di Napoli
2021
Garibaldi landed in Marsala on 11 May 1860. In July of the same year, the Thousand were still fighting in Sicily with the aim of reaching Calabria, where they would have arrived on 1 August, and from there marched to Naples. And on the very evening of 14 July, on the stage of Florentines theatre in Naples, the leading actor Tommaso Salvini (1829-1915) presented a mutilated Hamlet, deprived above all of the most introspective and sentimental scenes, whose interpretation is still preserved in his prompt-book of Hamlet. The declamatory symbols marked by Salvini are still readable in the prompt-book of his 1860 interpretation that is now housed at the Museo Biblioteca dell’Attore, in Genoa. Und…
Evolution of small prokaryotic genomes
2015
As revealed by genome sequencing, the biology of prokaryotes with reduced genomes is strikingly diverse. These include free-living prokaryotes with ∼800 genes as well as endosymbiotic bacteria with as few as ∼140 genes. Comparative genomics is revealing the evolutionary mechanisms that led to these small genomes. In the case of free-living prokaryotes, natural selection directly favored genome reduction, while in the case of endosymbiotic prokaryotes neutral processes played a more prominent role. However, new experimental data suggest that selective processes may be at operation as well for endosymbiotic prokaryotes at least during the first stages of genome reduction. Endosymbiotic prokar…
Amlodipine-induced gingival hyperplasia
2006
Drug-induced gingival hyperplasia is a serious concern both for the patient and the clinician. A 45 year-old Caucasian male patient with hypertension, who received amlodipine (10 mg/day, single dose orally) for two months, sought medical attention because of the new-onset gingival enlargement. On clinical examination a generalized and firm overgrowth of the gingival throughout the maxilla and the mandible were evident. The lack of gingival inflammation and purulent discharge were other features of the clinical scenario. Histological assessment of the biopsy specimen revealed the hyperplasia of connective tissue, epithelial acanthosis, and elongated rete ridges along with few inflammatory ce…
