Synergetic and redundant information flow detected by unnormalized Granger causality: application to resting state fMRI

2015

Objectives: We develop a framework for the analysis of synergy and redundancy in the pattern of information flow between subsystems of a complex network. Methods: The presence of redundancy and/or synergy in multivariate time series data renders difficult to estimate the neat flow of information from each driver variable to a given target. We show that adopting an unnormalized definition of Granger causality one may put in evidence redundant multiplets of variables influencing the target by maximizing the total Granger causality to a given target, over all the possible partitions of the set of driving variables. Consequently we introduce a pairwise index of synergy which is zero when two in…

Intrahepatic bile duct dilation and gallbladder hydrops due to a cystic duct stenosis in a 2-month-old boy.

2015

A 2-month-old boy presented with slight diffuse abdominal pain after an uncomplicated pregnancy and perinatal period. Height (62 cm) and weight (5.5 kg) were according to the age. Routine blood tests showed no abnormalities except for a minimal elevation of aspartate aminotransferase to 38 units/L (reference range 5–35 U/L). Primary abdominal ultrasound showed a dilation of the common bile duct and a gallbladder hydrops (figure 1). MR cholangiopancreatography (MRCP) was indicated to detect the cause for these incidental findings. Contrary to normal bile ducts in …

Pleistocene allopatric differentiation followed by recent range expansion explains the distribution and molecular diversity of two congeneric crustac…

2021

AbstractPleistocene glaciations had a tremendous impact on the biota across the Palaearctic, resulting in strong phylogeographic signals of range contraction and rapid postglacial recolonization of the deglaciated areas. Here, we explore the diversity patterns and history of two sibling species of passively dispersing taxa typical of temporary ponds, fairy shrimps (Anostraca). We combine mitochondrial (COI) and nuclear (ITS2 and 18S) markers to conduct a range-wide phylogeographic study including 56 populations of Branchinecta ferox and Branchinecta orientalis in the Palaearctic. Specifically, we investigate whether their largely overlapping ranges in Europe resulted from allopatric differe…

Slope units-based flow susceptibility model: using validation tests to select controlling factors

2011

A susceptibility map for an area, which is representative in terms of both geologic setting and slope instability phenomena of large sectors of the Sicilian Apennines, was produced using slope units and a multiparametric univariate model. The study area, extending for approximately 90 km2, was partitioned into 774 slope units, whose expected landslide occurrence was estimated by averaging seven susceptibility values, determined for the selected controlling factors: lithology, mean slope gradient, stream power index at the foot, mean topographic wetness index and profile curvature, slope unit length, and altitude range. Each of the recognized 490 landslides was represented by its centroid po…

Assessing Effects of Temperature Change on Four Limonium Species from Threatened Mediterranean Salt-Affected Habitats

2018

[EN] Evaluation of tolerance to temperatures in the germination stage is an important tool to foresee the possible effect of global warming. Moreover, establishing germination protocols for endemic and threatened species is most interesting for restoration and management plans that focus on habitat conservation. Seed germination was analysed in four species of the genus Limonium (L. virgatum, L. narbonense, L. girardianum and L. santapolense) growing in two saline habitats on the eastern coast of the Iberian Peninsula. The study aim was to compare responses of seed germination to different temperature regimes. Seeds were collected in two protected areas, `L¿Albufera de Valencia¿ (province o…

Can the absence of solvation of neutral reagents by ionic liquids be responsible for the high reactivity in base-assisted intramolecular nucleophilic…

2005

[reaction: see text] The kinetics of the rearrangement of the Z-phenylhydrazone of 3-benzoyl-5-phenyl-1,2,4-oxadiazole (1a) into the relevant 4-benzoylamino-2,5-diphenyl-1,2,3-triazole (2a) induced by amines have been studied in two room-temperature ionic liquids (IL-1, [BMIM][BF4] and IL-2, [BMIM][PF6]). The data collected show that the reaction occurs faster in ionic liquids than in other conventional solvents previously studied (both polar or apolar, protic or aprotic). Presumably, this could depend on their peculiar ability to minimize the strong substrate-solvent, amine-solvent and amine-amine interactions occurring in conventional solvents.

Wkład ks. prof. Alojzego Kleina (1934–2002) w recepcję uzgodnień katolicko-reformowanych

2017

Artykuł przedstawia postać ks. prof. Alojzego Kleina (1934–2002), wieloletniego dyrektora Instytutu Ekumenicznego im. J.A. Möhlera w Paderborn, mającego wielkie zasługi w rozwoju ruchu ekumenicznego ze strony Kościoła katolickiego. W opracowaniu ukazano jedynie mały wycinek jego dorobku naukowego – wkład w recepcję uzgodnień katolicko reformowanych. Skoncentrowano się na dwóch fazach tegoż dialogu: fazie dialogu chrystologicznego i fazie dialogu eklezjologicznego. Końcowa część syntetycznie zbiera wyniki badań i formułuje wnioski.
