Comments to the paper "do we really need new medical information about the Turin Shroud?".
2015
Abstract Following the interesting arguments raised in a recent letter to the editor, about a paper recently published in this journal, the authors are happy to take a cue from them to clarify some facts that have not been sufficiently treated for space. After a description of the methods used, arguments regarding a blunt trauma on the right shoulder with consequent dislocation, the position of the hands on the pubis with brachial plexus injury, and the wrist nailing that caused retracted thumbs are discussed in detail.
LA PARTICIÓN FOCO–TRASFONDO EN LAS ORACIONES INTERROGATIVAS DEL CATALÁN Y DEL ESPAÑOL: ESTUDIO DE CORPUS
2018
El catalán y el español expresan la partición foco-trasfondo (FR) de forma muy diferente (Villalba, 2007, 2011, Leonetti 2011, Planas-Morales y Villalba, 2015), especialmente en las oraciones interrogativas, en las cuales el catalán permite la dislocación a la derecha (DD) del trasfondo, en lugar de la omisión (recuperable por el clítico o la concordancia). Además, el español nunca expresa el trasfondo con la DD, sino que lo representa in situ. En esta comunicación, presentamos un estudio comparativo de corpus que demuestra que la partición FR de las oraciones interrogativas genera diferencias microparamétricas Catalan and Spanish express the focus-background (FB) partition of sentence in a…
La dislocació a la dreta en català i castellà: microvariació en la interfície sintaxi/pragmàtica
2007
This article investigates the use of right-dislocation in Catalan and Spanish. We have measured the productivity of right-dislocation in a corpus of an original Catalan text and its Spanish translation regarding four variables: category, grammatical function, discourse function, and distance with respect to the antecedent. The analysis shows that right-dislocation is a marginal phenomenon in Spanish, not only from a quantitative (10 occurrences vs. 232 occurrences in the Catalan text), but from a qualitative point of view: right-dislocation in Catalan affects all the categories, grammatical functions, discourse functions, and distances with respect to the antecedent, whereas in Spanish it i…
Shrinkage efficiency bounds: An extension
2023
Hansen (2005) obtained the efficiency bound (the lowest achievable risk) in the p-dimensional normal location model when p≥3, generalizing an earlier result of Magnus (2002) for the one-dimensional case (p=1). The classes of estimators considered are, however, different in the two cases. We provide an alternative bound to Hansen's which is a more natural generalization of the one-dimensional case, and we compare the classes and the bounds.
A dynamic analysis of SP 500, FTSE 100 and EURO STOXX 50 indices under different exchange rates.
2018
In this study, we assess the dynamic evolution of short-term correlation, long-term cointe-gration and Error Correction Model (hereafter referred to as ECM)-based long-term Granger causality between each pair of US, UK, and Eurozone stock markets from 1980 to 2015 using the rolling-window technique. A comparative analysis of pairwise dynamic integration and causality of stock markets, measured in common and domestic currency terms, is conducted to evaluate comprehensively how exchange rate fluctuations affect the time-varying integration among the S&P 500, FTSE 100 and EURO STOXX 50 indices. The results obtained show that the dynamic correlation, cointegration and ECM-based long-run Gra…

Flash-Floods Influence Macroinvertebrate Communities Distribution in Lotic Ecosystems
2019
Abstract Stream dwelling invertebrate populations are facing an ample array of stressors including the habitat imbalance caused by important floods. In this research we used a novel way to estimate the impact of floods upon the substrate, by utilising a remote variable named “flash-flood potential” (FFP), which accounts for the site slope and the average slope of the upstream catchment. The results showed that certain groups are sensitive to the influence of the FFP whereas other are not. We propose this remote variable as a surrogate for assessing stress imposed by floods and sediment scouring for lotic macroinvertebrates.
Statistical-based tolerance setting by eliciting the loss function reasoining
2009
An issue still open in the statistical-engineering literature concerns the tolerance allocation, i.e. the setting of admitted limits for critical characteristics or performances of interest of the system under study. A common approach to tolerance allocation is based on the idea of Loss function initially developed by Taguchi. Unfortunately, some obstacles prevent from a full exploitation of the Taguchi approach, since despite its clarity and elegance, it is poorly operational. Based on Taguchi’s proposal, researchers have been more concerned on developing different analytical models of loss function than clarifying the reasoning behind the loss function idea. So there is a missing link for…
Distributed routing and channel allocation in multi-channel multi-hop ad hoc networks
2013
In this paper, we propose a novel routing protocol which is integrated with channel assignment for multi-channel multi-hop wireless ad hoc networks. In such a network, each node is equipped with three transceivers. One is always tuned on a control channel which is responsible for control and broadcast messages, and the other two perform as transmitter and receiver respectively for traffic flows on different data channels. The routing protocol works in an on-demand manner, and the proposed routing discovery process selects a path that potentially traverses nodes with lighter traffic load and lower number of carried flows. With a given number of non-overlapping channels, the optimal solution …
A mini-slot-based cooperative MAC protocol for wireless mesh networks
2010
This paper proposes a TDMA-based medium access control protocol with cooperative communications enabled in wireless mesh networks. The proposed scheme is based on a multi-hop scenario which is extended from the conventional one-hop triangle cooperative transmission scenario. Benefiting from the elaborate mini-slot design, channel resources are fairly and efficiently allocated to each router so that no handshake is needed prior to every packet transmission. By giving priority for channel access to cooperative transmission performed by an optimal helper which is determined based on the received SNR, higher successful transmission rate can be achieved. Numerical results demonstrate that the pr…
