Transarterial chemoembolization versus sorafenib in patients with hepatocellular carcinoma and extrahepatic disease
2017
BackgroundSorafenib is the recommended treatment for advanced hepatocellular carcinoma (HCC), but transarterial chemoembolization (TACE) is performed in individual cases with limited extrahepatic spread. The aim of this study was to compare the outcome of patients with HCC and extrahepatic disease (EHD) treated with sorafenib and TACE.MethodsA total of 172 patients with HCC and EHD treated with sorafenib (n = 98) or TACE (n = 74) at three German referral centers (Hannover, Mainz and Hamburg) were included in this study. In order to reduce selection bias, patients were matched for significant demographic differences using a propensity score analysis.ResultsPatients with liver cirrhosis, high…

Image processing applications in object detection and graph matching : from Matlab development to GPU framework
2020
Automatically finding correspondences between object features in images is of main interest for several applications, as object detection and tracking, flow velocity estimation, identification, registration, and many derived tasks. In this thesis, we address feature correspondence within the general framework of graph matching optimization and with the principal aim to contribute, at a final step, to the design of new and parallel algorithms and their implementation on GPU (Graphics Processing Unit) systems. Graph matching problems can have many declinations, depending on the assumptions of the application at hand. We observed a gap between applications based on local cost objective functio…
Increasing the probability of finding an interaction in work stress research: A two-wave longitudinal test of the triple-match principle
2010
Research into work stress has attempted to identify job resources that can moderate the effects of job demands on strain. The recently developed triple-match principle (TMP) proposes that job demands, resources, and strain can be conceptualized as being composed of cognitive, emotional, and physical dimensions. When a psychological imbalance is induced by job demands, individuals activate corresponding resources to reduce the effects of the demands. A closer match occurs when the resources are processed in the same psychological domain as the demands. The further away from a match, the less likely an interactive effect will become. Put simply, the likelihood of finding an interactive effect…
University Performance Before and During Economic Crises. An Analysis of Graduate Characteristics
2020
The aim of this book is to analyze the performance of some Italian universities during a pre-crisis period and an economic crisis period, on the basis of graduate characteristics and graduate placement statistics. The Electre model is used to produce eighteen university rankings according to three different scenarios (Neutral, University and Job), three different roles ascribed to the key criteria (overeducation and mismatching), and two years corresponding to two postgraduation placement sampling surveys carried out in a pre-crisis period (2006) and during a crisis period (2011). The eighteen rankings are based on Economics/Statistics and Political & Social Sciences graduates. The rank…
Cross-age effects on forensic face construction
2015
This work was supported in part by an award from the UK Economic and Social Research Council (RES-000-22-4150) to Dr Charity Brown and Dr Charlie Frowd The own-age bias (OAB) refers to recognition memory being more accurate for people of our own age than other age groups (e.g., Wright and Stroud, 2002). This paper investigated whether the OAB effect is present during construction of human faces (also known as facial composites, often for forensic/police use). In doing so, it adds to our understanding of factors influencing both facial memory across the life span as well as performance of facial composites. Participant-witnesses were grouped into younger (19-35 years) and older (51-80 years)…
[Atrial fibrillation in patients with COVID-19. Usefulness of the CHA
2021
Resumen Introduccion y objetivos La enfermedad por coronavirus de 2019 (COVID-19) esta causada por el segundo coronavirus del sindrome respiratorio agudo y grave. La fibrilacion auricular (FA) es comun en situaciones agudas, en las que conlleva mas complicaciones y mortalidad. Metodos Analisis del Registro internacional HOPE (NCT04334291); el objetivo es evaluar la informacion pronostica de FA en pacientes con COVID-19. Se realizo un analisis multivariable y un emparejamiento por puntuacion de propension para evaluar la relacion entre FA y mortalidad. Ademas, se evaluo en estos pacientes el impacto en la mortalidad y los eventos embolicos de la puntuacion CHA2DS2-VASc. Resultados Entre los …
The veridical perception of object temperature with varying skin temperature.
1988
The effect of skin-adaptation temperature on object-temperature perception was investigated, using the method of dichiric matching, in an attempt to determine whether veridical perception of physical object temperature occurs in human subjects. Observers were presented with a test temperature on one hand and required to find a matching temperature, that is, one that produced the same sensation, on the other, differently adapted, hand. Using equality of test and matching temperatures as a criterion of veridical perception, it was found that the latter improves with ΔT, the difference between object temperature and skin-adaptation temperature. It is postulated that when ΔT is close to zero, v…
