Non-branching geodesics and optimal maps in strong CD(K,∞) -spaces
2014
We prove that in metric measure spaces where the entropy functional is Kconvex along every Wasserstein geodesic any optimal transport between two absolutely continuous measures with finite second moments lives on a non-branching set of geodesics. As a corollary we obtain that in these spaces there exists only one optimal transport plan between any two absolutely continuous measures with finite second moments and this plan is given by a map. The results are applicable in metric measure spaces having Riemannian Ricci curvature bounded below, and in particular they hold also for Gromov-Hausdorff limits of Riemannian manifolds with Ricci curvature bounded from below by some constant. peerReview…
The Forgotten Representatives of the School of Mathematics in Sciences of Management
2017
Szybki rozwój technologii, wzrost poziomu życia i zmiany demograficzne przyczyniają się do dynamicznych zmian zachodzących we współczesnym społeczeństwie. Specjaliści w dziedzinie demografii, zwracają szczególną uwagę na zjawisko „starzejącego się społeczeństwa”, co przyczyni sie do wzrostu zapotrzebowania na usługi medyczne świadczone przez lekarzy specjalizujących się w leczeniu ludzi starszych, oraz miejsca w ośrodkach opiekuńczo-leczniczych (sanatoriach czy hospicjach). Głównym celem niniejszego opracowania była ocena pozycji Polski na tle krajów Unii Europejskiej na podstawie wybranych wskaźników charakteryzujących system opieki zdrowotnej. W badaniach starano sie odpowiedzieć na pytan…
Applicability of a displaced-beam laser scintillometer in a sparse tall Mediterranean vegetation
2009
Recent studies showed that the sensible heat flux (H) measured with an array of eddy-correlation system has an high spatial and temporal variability over sparse tall vegetation, such as olive trees, whereas H determined with a displaced-beam laser scintillometer (DBLS) appeared to behave more stable. In this study, the results are shown of two field experiments performed over an olive tree plantation in Sicily in 2007 and 2008, in order to investigate the applicability of a DBSL in combination with remote sensing techniques for the actual evapotranspiration assessment. In 2007 the laser beams was closer to the top of the canopy than in 2008. Various aspects of the scintillation method will …
Assessment of the Inter-Batch Variability of Microstructure Parameters in Topical Semisolids and Impact on the Demonstration of Equivalence
2019
Demonstration of similar microstructure is essential for demonstrating the equivalence of generic topical products since the microstructure of semisolids may affect the drug release. The objective of this study was to compare the microstructure-defining physical parameters of different batches of a reference ointment containing calcipotriol and betamethasone (Daivobet 50 µ
Different Measurement Setup Configurations for Space Charge test in Mini Cable Specimens with the PEA Method
2019
Under DC stress, the space charge accumulation is believed one of the most responsible of dielectrics ageing. For this reason, due to the increase of the HVDC transmission, a recommendation has been proposed. The latter want to introduce the space charge measure, with the PEA method, in cable specimens during the prequalification or type tests. Considering the several issues related to this kind of measures the aim of the proposed work is find a measurement setup for mini cable specimens which is able to provide a clear and clean space charge profile. Therefore, different tests have been made in this work. In particular, the length of the cable specimen, the width of the pulse electrodes, a…
Violenze “di genere” e violenze “sulle donne”: problemi di definizione e di rilevazione empirica
2020
Il capitolo punta a problematizzare gli aspetti definitori del concetto di “violenza di genere” e quelli legati più strettamente alla sua rilevazione/misurazione, cercando di fornire un contributo all’utilizzo delle statistiche sul tema in maniera avveduta e consapevole. The chapter aims to problematize the defining aspects of the concept of "gender violence" and those related more closely to its detection / measurement, trying to provide a contribution to the use of statistics on the subject in a prudent and conscious manner.
L’attività normativa del governo nel periodo 2020-2021
2022
L’articolo descrive l’attività normativa del governo nel periodo 2020-2021. Il biennio è stato segnato dalle misure di contrasto alla pandemia da Covid-19. Di conseguenza, si prendono in considerazione, innanzitutto, le misure sanitarie adottate nel periodo emergenziale e concernenti tanto gli obblighi di distanziamento fisico e di contenimento dell’epidemia, quanto le disposizioni relative alle vaccinazioni e alla presentazione del «certificato verde» o green pass. Successivamente, si dà conto delle principali normative adottate a supporto dell’economia e del sistema imprenditoriale, distinguendo tra gli ausili finanziari destinati a ridurre l’impatto negativo della pandemia sulle aziende …
Mobility determination of lead isotopes in glass for retrospective radon measurements rad
2008
In retrospective radon measurements, the 22-y half life of 210Pb is used as an advantage. 210Pb is often considered to be relatively immobile in glass after alpha recoil implanted by 222Rn progenies. The diffusion of 210Pb could, however, lead to uncertain wrong retrospective radon exposure estimations if 210Pb is mobile and can escape from glass, or lost as a result of cleaning-induced surface modification. This diffusion was studied by a radiotracer technique, where 209Pb was used as a tracer in a glass matrix for which the elemental composition is known. Using the ion guide isotope separator on-line technique, the 209Pb atoms were implanted into the glass with an energy of 39 keV. The di…
An EEMD Aided Comparison of Time Histories and Its Application in Vehicle Safety
2017
In the context of signal processing, the comparison of time histories is required for different purposes, especially for the model validation of vehicle safety. Most of the existing metrics focus on the mathematical value only. Therefore, they suffer the measuring errors, disturbance, and uncertainties and can hardly achieve a stable result with a clear physical interpretation. This paper proposes a novel scheme of time histories comparison to be used in vehicle safety analysis. More specifically, each signal for comparison is decomposed into a trend signal and several intrinsic mode functions (IMFs) by ensemble empirical mode decomposition. The trend signals reflect the general variation a…
Dynamic Magnetic and Optical Insight into a High Performance Pentagonal Bipyramidal Dy(III) Single-Ion Magnet
2017
The pentagonal bipyramidal single-ion magnets (SIMs) are among the most attractive prototypes of high-performance single-molecule magnets (SMMs). Here, a fluorescence-active phosphine oxide ligand CyPh2PO (=cyclohexyl(diphenyl)phosphine oxide) was introduced into [Dy(CyPh2PO)2(H2O)5]Br3⋅2 (CyPh2PO)⋅EtOH⋅3 H2O, and combined dynamic magnetic measurement, optical characterization, ab initio calculation, and magneto-optical correlation of this high-performance pseudo-D5h DyIII SIM with large Ueff (508(2) K) and high magnetic hysteresis temperature (19 K) were performed. This work provides a deeper insight into the rational design of promising molecular magnets. peerReviewed
