Spherical Top Theory and Molecular Spectra

2011

In this article, we present an overview of the present state of the art of the theory of high-resolution spherical-top spectra in the framework of the effective Hamiltonian approach. We describe the specific features of this class of molecules to explain the basic concepts of the theoretical methods used for the analysis (line positions and intensities) and the simulation of absorption (including pure rotation) and Raman spectra of such species. The non conventional formalism that we use is essentially based on irreducible tensor methods and is especially adapted to computational treatments and global analyses of complex interacting band systems. We give examples concerning mainly methane (…

Virtualization of work in global supply chains

2016

ABSTRACT. Background: The paper is devoted to the notion and benefits of implementing virtual work in global supply chains. Virtual work must be understood as an intentional activity of a human being, aimed at rendering services (tangible and intangible), by means of ITC tools, performed in a distance from the traditional place of work, in a mobile manner. The empirical research were conducted on the basis of 4 case studies of global leaders of supply chains, which in accordance with M. Fisher's classification, represent two types. The case studies confirmed the positive influence of virtual work both in effective and flexible supply chains. Favourable market and technological conditions an…

INTRODUCTION Global economic crisis significantly increases the pressure on reduction of cost and risk connected with the functioning of global supply chains. Among many ways to reduce the cost and the uncertainty of demand for the products of supply chain the essential one is the increase of information transparency due to modern ICT solutions.

Superfluid weight and Berezinskii-Kosterlitz-Thouless transition temperature of twisted bilayer graphene

2019

We study superconductivity of twisted bilayer graphene with local and non-local attractive interactions. We obtain the superfluid weight and Berezinskii-Kosterlitz-Thouless (BKT) transition temperature for microscopic tight-binding and low-energy continuum models. We predict qualitative differences between local and non-local interaction schemes which could be distinguished experimentally. In the flat band limit where the pair potential exceeds the band width we show that the superfluid weight and BKT temperature are determined by multiband processes and quantum geometry of the band.

6-Methyluracil: a redetermination of polymorph (II)

2019

6-Methyluracil, C5H6N2O2, exists in two crystalline phases: form (I), monoclinic, space group P21/c [Reck et al. (1988). Acta Cryst. A44, 417–421] and form (II), monoclinic, space group C2/c [Leonidov et al. (1993). Russ. J. Phys. Chem. 67, 2220–2223]. The structure of polymorph (II) has been redetermined providing a significant increase in the precision of the derived geometric parameters. In the crystal, molecules form ribbons approximately running parallel to the c-axis direction through N—H...O hydrogen bonds. The radical differences observed between the crystal packing of the two polymorphs may be responsible in form (II) for an increase in the contribution of the polar canonical forms…

Association between oral HSV-1 and survival in allogeneic hematopoietic stem cell transplanted patients

2009

Introduction: This study was designed to investigate the effect of oral HSV-1 shedding on the survival of allogeneic hematopoietic stem cell transplanted (allo-HSCT) patients. Methods: One hundred nineteen allo-HSCT patients were included in the study and divided in three groups: before transplant, 100 days after transplant and 1 year of allo-HSCT. Healthy volunteers matched by age and gender were also selected. Oral swabs were performed and the nested PCR was used to detect HSV-1 presence in the oral mucosa. In statistical analysis, chi-square test was used to test the distribution of HSV1 shedding among the three groups. Time to death after allo-HSCT was displayed by means of the Kaplan-M…

Data from: New insights on water buffalo genomic diversity and post-domestication migration routes from medium density SNP chip data

2019

The domestic water buffalo is native to the Asian continent but through historical migrations and recent importations, nowadays has a worldwide distribution. The two types of water buffalo, i.e., river and swamp, display distinct morphological and behavioral traits, different karyotypes and also have different purposes and geographical distributions. River buffaloes from Pakistan, Iran, Turkey, Egypt, Romania, Bulgaria, Italy, Mozambique, Brazil and Colombia, and swamp buffaloes from China, Thailand, Philippines, Indonesia and Brazil were genotyped with a species-specific medium-density 90K SNP panel. We estimated the levels of molecular diversity and described population structure, which r…
