Measuring galaxy segregation with the mark connection function

2010

(abridged) The clustering properties of galaxies belonging to different luminosity ranges or having different morphological types are different. These characteristics or `marks' permit to understand the galaxy catalogs that carry all this information as realizations of marked point processes. Many attempts have been presented to quantify the dependence of the clustering of galaxies on their inner properties. The present paper summarizes methods on spatial marked statistics used in cosmology to disentangle luminosity, colour or morphological segregation and introduces a new one in this context, the mark connection function. The methods used here are the partial correlation functions, includi…

Overview and prerequisites of well-functioning Latvian national innovation system

2013

Analysis and understanding of the national innovation system can help policy-makers to identify strategies for improving innovative performance and overall competitiveness of the national economy. Nowadays we know too little about how to identify and measure specific problems in the system (if at all possible), despite several attempts to define them. Until now, little analysis on the Latvian innovation system was made. The paper aims to analyse the Latvian national innovation system and to provide a factors of well-functioning Latvian national innovation system. This research gives a possibility to researchers and policy-makers to investigate the mismatch between policies and problems and …

Procesos de autonomia normativa entre perfiles de indipendencia e interdependencia funcional

2010

The author says that to get rules technique and the certainty of the law together is quite a postulate. The certainty of rules is the expression of impartiality and guarantee which should be assured by the "fixity" of the law.Neverthless one can point out the insufficinet reconnaissance of the rules seen as pure written record, that is the "liturgic text" to individuate the real content of the law. The author gives variegated exemplifications about it. Viceversa the rule exists because it is "alive", and in it is its effective vitality. So it exists in the semantics and in the jurisdictional control and in its applicability. After all, the matter of law is a matter of fact. The specific fac…

Labor market matching with application to Finnish data

2014

This thesis studies labor market matching and takes use of a matching function, which describes the technology how unemployed job seekers and vacant jobs search, meet and form new employment relationships. The goal of the study is twofold: First is to provide a comprehensive critical review of previous literature covering both micro models as well as empirical applications. Major limitations in empirical studies are imperfect measures of variables as well as inability to account for all relevant factors making results methodology-sensitive. The second contribution is to estimate a matching function for Finland using annual data from 2006-2012 and thus giving the most recent knowledge on the…

Maladaptive stress coping: An additional psychological factor in the process of chronification of pain or pruritus

2021

Background: Inflammatory skin diseases with chronic pruritus and chronic back pain are very common symptoms in the general population and are associated with a reduced quality of life (QOL). In addition to biological factors, psychosocial reasons are also considered to be responsible for their development. So far, it is not known whether chronic pruritus and chronic back pain are related to maladaptive stress coping. Patients and methods: In our matched pilot case-control study with a total of 259 analyzed subjects, we compared outpatient groups, one suffering from chronic skin diseases with pruritus, the other with chronic back pain, to a healthy control group in terms of their stress copi…

Functional linear models for the analysis of similarity of waveforms

2018

In seismology methods based on waveform similarity analysis are adopted to identify sequences of events characterized by similar fault mechanism and prop- agation pattern. Seismic waves can be considered as spatially interdependent three dimensional curves depending on time and the waveform similarity analysis can be configured as a functional clustering approach, on the basis of which the member- ship is assessed by the shape of the temporal patterns. For providing qualitative ex- traction of the most important information from the recorded signals we propose an integration of the metadata, related to the waves, as explicative variables of a func- tional linear models. The temporal pattern…

The Radó–Kneser–Choquet theorem for $p$-harmonic mappings between Riemannian surfaces

2020

In the planar setting the Rad\'o-Kneser-Choquet theorem states that a harmonic map from the unit disk onto a Jordan domain bounded by a convex curve is a diffeomorphism provided that the boundary mapping is a homeomorphism. We prove the injectivity criterion of Rad\'o-Kneser-Choquet for $p$-harmonic mappings between Riemannian surfaces. In our proof of the injecticity criterion we approximate the $p$-harmonic map with auxiliary mappings that solve uniformly elliptic systems. We prove that each auxiliary mapping has a positive Jacobian by a homotopy argument. We keep the maps injective all the way through the homotopy with the help of the minimum principle for a certain subharmonic expressio…

Quantitative reconstruction of hydroclimate variability over the last 200 kyr in the West Mediterranean

2022

The data show the quantitative annual, winter and summer precipitation reconstructions (mm/yr) from southern Iberian Peninsula for the last ~200,000 years (Camuera et al., 2022), based on the previously published fossil pollen data from the Padul-15-05 lake sediment record (Ramos-Román et al., 2018a, b; Camuera et al., 2019, 2021). The Padul-15-05 record, located in southern Spain (37º00'39''N, 3º36'14''W, 726 masl), was retrieved during summer 2015 from the current edge of the lake using a Rolatec RL-48-L hydraulic percussion coring machine. The quantitative precipitation reconstructions were performed using the performance statistics of the Weighted Averaging-Partial Least Squares (WA-PLS…

1H NMR Urinary Metabolomic Analysis in Older Adults after Hip Fracture Surgery May Provide Valuable Information for Patient Profiling : A Preliminary…

2022

In these times of precision and personalized medicine, profiling patients to identify their needs is crucial to providing the best and most cost-effective treatment. In this study, we used urine metabolomics to explore the characterization of older adults with hip fractures and to explore the forecasting of patient outcomes. Overnight urine specimens were collected from 33 patients (mean age 80 ± 8 years) after hip fracture surgery during their stay at a rehabilitation hospital. The specimens were analyzed with 1H NMR spectroscopy. We performed a metabolomics study regarding assessments of frailty status, Functional Independence Measure (FIM), and Short Physical Performance Battery (SPPB). …
