Mutation Analysis of LMX1B Gene in Nail-Patella Syndrome Patients
1998
SummaryNail-patella syndrome (NPS), a pleiotropic disorder exhibiting autosomal dominant inheritance, has been studied for >100 years. Recent evidence shows that NPS is the result of mutations in the LIM-homeodomain gene LMX1B. To determine whether specific LMX1B mutations are associated with different aspects of the NPS phenotype, we screened a cohort of 41 NPS families for LMX1B mutations. A total of 25 mutations were identified in 37 families. The nature of the mutations supports the hypothesis that NPS is the result of haploinsufficiency for LMX1B. There was no evidence of correlation between aspects of the NPS phenotype and specific mutations.
IR Bandshapes of Intramolecularly H-Bonded Systems II. 2,4-Dibromophenol
1984
A detailed quantitative study of the IR bandshape of the ϑs(OH) vibration of 2,4-dibromophenol in a series of solvents is presented.A distinct dependence of band positions, shape parameters, correlation functions and correlation times from solvent polarity has been found.The contribution of various shaping mechanisms to the profile is discussed.
ANALYSIS OF BUSINESS CYCLES CONVERGENCE IN A SWITCHING REGIME VIEW
2012
In this paper I analyzed the convergence between Romanian and Euro Zone`s business cycles using a Switching approach. Considering the evolution of final consumption expenditure as proxy for the business cycles, the underlying study is calibrated on the second key feature of Burns and Mitchell`s (1946) definition about business cycles, namely the cycles are divided and also treated differently for cases of expansionary and downward regimes. Therefore a cyclical convergence between Romanian and Euro Zone`s business cycles is characterized by synchronization in the occurrence of different regimes (states) and also in the time for which these regimes are standing up. For this purpose, I called …
CLASSIFICATION OF EUROPEAN UNION COUNTRIES ACCORDING TO NATIONAL COMPETITIVENESS AND SOVEREIGN DEBT LEVELS
2013
National competitiveness is defined by World Economic Forum as "the set of institutions, policies, and factors that determine the level of productivity of a country". Therefore, the competitiveness of the European Union member states will be analyzed in the context of the governments' economic policies implemented in the previous period that had as main effects an increased public debt and an exposure of European Union to sovereign debt crisis. This paper attempts to examine how public debt takes its toll on the competitiveness of the EU member countries. So, the researchers will explore the strength of the connection between the percentage of public debt in GDP and the national competitive…
STUDY REGARDING THE ANALYSIS OF THE FINANCIAL SITUATION OF THE SOCIETIES FROM THE PHARMACEUTICAL INDUSTRY IN TERMS OF THE CORRELATION BETWEEN THE LIQ…
2015
The relationship between different rates of liquidity and profitability, is one of the most popular topics of research in the financial management field. In order to demonstrate the correlation between these variables, we used the statistical program SPSS. The analyzed societies are: Zentiva, Biofarm and Antibiotice Iasi, listed at the Bucharest Stock Exchange. The research leads to the conclusion that all the societies have sufficient liquidity to cover the payment obligations. Also, using the Pearson correlation coefficient, we demonstrated the fact that the liquidity is one of the indicators that determine the profitability of the analyzed societies.
CORRELATION ANALYSIS FOR TOURISM HEDONIC AND UTILITARIAN MOTIVATORS IN THE DECISION MAKING PROCESSÂ
2013
For centuries, the marketing concept claims that organizations must forecast and satisfy consumer needs if their goals are to make profit and develop a connection with their customers. The marketing concept plays a vital role because consumers have a variety of choices and lately, they are better educated, with eagerness in spending and they are capable to shop around much more in order to purchase everything that satisfy their needs and expectations. In this line of ideas, this study examines correlations between consumer motivators to buy a tourism package.
Jet shape modification in Pb-Pb collisions at √S[sub]N[sub]N= 2.76 TeV using two-particle correlations
2018
This thesis focuses on two separate topics. The first topic concerns the upgrade of the Time Projection Chamber (TPC) detector of the ALICE experiment. The upgrade will take place during the second Long Shutdown (2019-2020). The part of the upgrade I participated in was the replacement of the detector’s current readout electronics with Gas Electron Multiplier (GEM) foils. This change would allow for the continuous readout of the data, resulting in a hundredfold increase in the amount of data the ALICE experiment can process, as the TPC is the central tracking detector. I was involved in the Quality Assurance (QA) of these GEM foils. The advanced QA procedure consists of three measurements, a…
Freeze-out radii extracted from three-pion cumulants in pp, p–Pb and Pb–Pb collisions at the LHC
2014
In high-energy collisions, the spatio-temporal size of the particle production region can be measured using the Bose-Einstein correlations of identical bosons at low relative momentum. The source radii are typically extracted using two-pion correlations, and characterize the system at the last stage of interaction, called kinetic freeze-out. In low-multiplicity collisions, unlike in high-multiplicity collisions, two-pion correlations are substantially altered by background correlations, e.g. mini-jets. Such correlations can be suppressed using three-pion cumulant correlations. We present the first measurements of the size of the system at freeze-out extracted from three-pion cumulant correl…
Linking the residential satisfaction to landscape metrics: a tool for urban planning?
2010
International audience; This paper examines the links between residential satisfaction of periurban households and landscape structure of their spatial neighbourhood. Satisfaction of people was measured using a survey while landscape composition was quantified from remotely sensed data. Results are simulated in order to identify areas of satisfaction.
Digital Correlation Method Based on Micro-geometrical Texture Pattern for Strain Field Measurement
2011
International audience; Image correlation methods are widely used in experimental mechanics to obtain displacement field measurements. Currently, these methods are applied using digital images of the initial and deformed surfaces sprayed with black or white paint. Speckle patterns are then captured and the correlation is performed with a high degree of accuracy to an order of 0.01 pixels. In 3D, however, stereo-correlation leads to a lower degree of accuracy. Correlation techniques are based on the search for a sub-image (or pattern) displacement field. The work presented in this paper introduces a new correlation-based approach for 3D displacement field measurement that uses an additional …
