Computational investigation and experimental considerations for the classical implementation of a full adder on SO2 by optical pump-probe schemes
2008
International audience; Following the scheme recently proposed by Remacle and Levine Phys. Rev. A 73, 033820 2006 , we investigate the concrete implementation of a classical full adder on two electronic states X˜ 1A1 and C ˜ 1B2 of the SO2 molecule by optical pump-probe laser pulses using intuitive and counterintuitive stimulated Raman adiabatic passage excitation schemes. The resources needed for providing the inputs and reading out are discussed, as well as the conditions for achieving robustness in both the intuitive and counterintuitive pump-dump sequences. The fidelity of the scheme is analyzed with respect to experimental noise and two kinds of perturbations: The coupling to the neigh…
SMS Messages in a Daily Finnish Newspaper : The Contect of Proverb Performances
2017
The article focuses on Finnish proverbs as a part of contemporary colloquial written language in everyday use and context. The article offers a view on what is happening with proverbs in the vernacular in Finnish everyday life. Most traditional Finnish proverbs originate from an agrarian context and still use agrarian language, even if nowadays they live in a new context with a new meaning. As empirical material this article uses a special case that demonstrates the use of proverbs in one Finnish newspaper: proverbs in SMS messages published as a letter to the editor in a newspaper. *** Avtorica se osredinja na finske pregovore kot del sodobnega pogovornega pisnega jezika v vsakdanji rabi i…
"Mais... je ne visite pas!". Une approche ethnographique de l'usage faible des œuvres
2013
Some photographic exhibitions are nowadays set outdoors in order to popularize art. Through a case study, this article examines the "weak use of images" as it is practised in public places, by passers-by who do not identify art pieces as such, and do not consider themselves as visitors. Their relation to art pieces, in this context, is built on an apparent paradox (they relate and at the same time do not relate to the pieces), and constitutes the minor mode of situations and observed interactions (this relation does not organise or structure the latter).
Drivers and outcomes of consumer engagement : Insights from mobile money usage in Ghana
2019
Purpose The purpose of this paper is to examine the drivers of consumer engagement and its consequences via the experiences of mobile money services’ users in Ghana and to discuss its implications for the society, financial service innovation, delivery and operations. Design/methodology/approach A pre-tested survey instrument was used with a sample of 595 mobile money services users in Ghana. SmartPLS application was used to analyze the data and report findings. Findings The study shows that perceived risk, consumer empowerment, subjective norm, performance expectancy and effort expectancy influence the affect component of consumer engagement and explain around half of its variance. The ef…
Comparative Molecular Evolution of Primary (Buchnera) and Secondary Symbionts of Aphids Based on Two Protein-Coding Genes
2001
A+T content, phylogenetic relationships, codon usage, evolutionary rates, and ratio of synonymous versus non-synonymous substitutions have been studied in partial sequences of the atpD and aroQ/pheA genes of primary ( Buchnera) and secondary symbionts of aphids and a set of selected non-symbiotic bacteria, belonging to the five subdivisions of the Proteobacteria. Compared to the homologous genes of the last group, both genes belonging to Buchnera behave in a similar way, showing a higher A+T content, forming a monophyletic group, a loss in codon bias, especially in third base position, an evolutionary acceleration and an increase in the number of non-synonymous substitutions, confirming pre…
Biodiversity and dairy traits of lactic acid bacteria from foliage of aromatic plants before and after dehydration process monitored by a smart senso…
2020
ABSTRACT The main hypothesis of this work was to evaluate the presence of lactic acid bacteria (LAB) intrinsically resistant to plant essential oils in sage (Salvia officinalis L.) and laurel (Laurus nobilis), for future applications in functional cheese production by addition of aromatic herbs. The effect of the drying process on the viability of LAB was evaluated with three biomass densities (3, 4 and 5 kg/m2). The drying densities did not affect weight loss, but influenced the levels of LAB of sage and laurel. A total of 10 different strains of Enterococcus faecium, Enterococcus mundtii, Enterococcus raffinosus and Leuconostoc mesenteroides were identified from laurel, while sage did not…
Quantification of a novel group of nitrate-reducing bacteria in the environment by real-time PCR
2004
Abstract Nitrate reduction is performed by phylogenetically diverse bacteria. Analysis of narG (alpha subunit of the membrane bound nitrate reductase) trees constructed using environmental sequences revealed a new cluster that is not related to narG gene from known nitrate-reducing bacteria. In this study, primers targeting this as yet uncultivated nitrate-reducing group were designed and used to develop a real-time SYBR® Green PCR assay. The assay was tested with clones from distinct nitrate-reducing groups and applied to various environmental samples. narG copy number was high ranging between 5.08×108 and 1.12×1011 copies per gram of dry weight of environmental sample. Environmental real-…
Cloning and sequencing of the dnaK region of Streptomyces coelicolor A3(2)
1993
Abstract The dnaK homologue of Streptomyces coelicolor A3(2) strain M145 has been cloned and sequenced. Nucleotide sequence analysis of a 2.5-kb region revealed an open reading frame (ORF) encoding a predicted DnaK protein of 618 amino acids (Mr = 66 274). The dnaK coding sequence displays extreme codon bias and shows a strong preference for CGY and GGY, for Arg and Gly codons, respectively. The predicted DnaK sequence has a high Lys:Arg ratio which is not typical of streptomycete proteins. The region immediately downstream from dnaK contains an ORF for a GrpE-like protein; the predicted start codon of grpE overlaps the last two codons of dnaK, indicating that the two genes are translationa…
A cluster of cuticle protein genes of Drosophila melanogaster at 65A: sequence, structure and evolution
1997
0016-6731 (Print) Journal Article Research Support, Non-U.S. Gov't Research Support, U.S. Gov't, Non-P.H.S.; A 36-kb genomic DNA segment of the Drosophila melanogaster genome containing 12 clustered cuticle genes has been mapped and partially sequenced. The cluster maps at 65A 5-6 on the left arm of the third chromosome, in agreement with the previously determined location of a putative cluster encompassing the genes for the third instar larval cuticle proteins LCP5, LCP6 and LCP8. This cluster is the largest cuticle gene cluster discovered to date and shows a number of surprising features that explain in part the genetic complexity of the LCP5, LCP6 and LCP8 loci. The genes encoding LCP5 a…
Connection between optimal control theory and adiabatic-passage techniques in quantum systems
2012
This work explores the relationship between optimal control theory and adiabatic passage techniques in quantum systems. The study is based on a geometric analysis of the Hamiltonian dynamics constructed from the Pontryagin Maximum Principle. In a three-level quantum system, we show that the Stimulated Raman Adiabatic Passage technique can be associated to a peculiar Hamiltonian singularity. One deduces that the adiabatic pulse is solution of the optimal control problem only for a specific cost functional. This analysis is extended to the case of a four-level quantum system.
