Elementary presentation of self‐consistent intermediate Hamiltonians and proposal of two totally dressed singles and doubles configuration interactio…
1994
Intermediate Hamiltonians are effective Hamiltonians which are defined on an N‐dimensional model space but which only provide n<N exact eigenvalues and the projections of the corresponding eigenvectors onto the model space. For a single root research, the intermediate Hamiltonian may be obtained from the restriction of the Hamiltonian to the model space by an appropriate, uniquely defined dressing of the diagonal energies or of the first column. Approximate self‐consistent dressings may be proposed. The simplest perturbative form gives the same result as the original 2nd order intermediate Hamiltonian or the ‘‘shifted Bk’’ technique but it is of easier implementation. Self‐consistent inclus…
Resting the mind – A novel topic with scarce insights. Considering potential mental recovery strategies for short rest periods in sports
2019
Abstract Both meticulously structured trainig routine as well as specific characteristics of various sports (e.g., swimming, shooting, modern pentathlon) with multiple competition bouts in a single day appear to be mentally demanding and may result in a state of mental fatigue. Due to these multidimensional demands, adequate training and competition recovery is essential. Consequently, the idea of mental recovery embraces the spotlight of research. On training and competition days, short rest periods implemented as a vital part, can be used for mental recovery and can help in assisting athletes to return to baseline levels of mental abilites (e.g., concentration, attention). Sport-specific …
Root Canal Morphology and Configuration of the Mandibular Canine: A Systematic Review
2021
The aim of this study was to systematically review the root canal morphology and configuration (RCC) of mandibular canines (MaCa). The review was registered in the PROSPERO database (ID-272297) and it was carried out following the PRISMA guidelines. Three electronic databases (MEDLINE via PubMed, Embase, Scopus) were searched. Randomized controlled trials, cross-sectional, cohort, comparative, evaluation and validation studies have been included. The anatomical quality assessment (AQUA) tool was used for a quality assessment of the anatomical studies. Of 910 studies retrieved from the systematic search, 28 studies investigating RCCs were included. Most MaCa were single-rooted (87.9–100%), w…
Coordinate space calculation of two- and three-loop sunrise-type diagrams, elliptic functions and truncated Bessel integral identities
2019
We integrate three-loop sunrise-type vacuum diagrams in $D_0=4$ dimensions with four different masses using configuration space techniques. The finite parts of our results are in numerical agreement with corresponding three-loop calculations in momentum space. Using some of the closed form results of the momentum space calculation we arrive at new integral identities involving truncated integrals of products of Bessel functions. For the non-degenerate finite two-loop sunrise-type vacuum diagram in $D_0=2$ dimensions we make use of the known closed form $p$-space result to express the moment of a product of three Bessel functions in terms of a sum of Claussen polylogarithms. Using results fo…
"How to make a mountain out of a molehill": a corpus-based pragmatic and conversational analysis study of hyperbole in interation.
2006
Since antiquity figures have been widely studied within the framework of rhetoric, although contemporary rhetoric has tended to disregard their importance and relegate their study to the domain of literary criticism. However, since the 1980s, there has been a renewed interest in figurative language not only in literary studies, but also in other fields of research. Indeed, research on figuration has emerged as a new and distinct discipline, namely figurative language studies. However, within this framework, metaphor and irony have received the greatest attention, while other non-literal forms have been largely ignored. This is certainly the case of hyperbole, a long neglected trope despite …
Multiplet coupling and band structure in L2,3-edge XAS through multi-channel multiple scattering theory.
2009
International audience; Using the recently developed multi-channel multiple scattering (MCMS) method we have calculated the x-ray absorption spectra (XAS) at the L2,3-edge of transition metal compounds. The MCMS method is an ab initio scheme which combines an accurate description of the band structure of the material with a correlated many-electron wave function on the absorber atom. Thereby configuration interaction in the XAS final state, in particular multiplet effects, can be taken into account. In the present implementation, we use an electron-hole wave function and treat the interaction with all other electrons on a mean-field level. The calculated spectra agree well with experiment f…
Mapping the political toponymy of educational namescapes: A quantitative analysis of Romanian school names
2019
Abstract This study sets out to map the political toponymy of Romanian schooling network. Starting from the theoretical premise that national memory is toponymically inscribed, inter alia, on a series of public organizations that form an institutional namescape, the paper reads the Romanian historical memory through the looking glass of school names. Exhaustive data was collected for the Romanian secondary schools bearing a nominal identity (N = 2850). Data were analyzed in terms of the ethnic and gender distribution, the social (occupational), spatial, and historical structures of the Romanian educational namescape. Our findings reveal that the political toponymy of the Romanian schooling …
Mans mnemòniques en l’Ars demonstrativa de Ramon Llull
2014
Aquest article recupera el concepte d’art de la memòria aplicat a les obres de Ramon Llull a partir de la presentació i el comentari de figures de mans amb finalitats mnemotècniques, especulatives i predicadores, que es troben en els manuscrits lul·lians de l’Ars demonstrativa –escrita el 1283– datats del segle xiii i el xvi. En els manuscrits de Venècia (Bibl. Marciana, Lat. VI. 200), de Bèrgam (MA 365) i de San Candido (B. della Collegiata, VIII C.8), la mà està vinculada a la figura S de l’Ars demonstrativa. En el ms &.IV.6 de l’Escorial, en canvi, la mà representa la figura A. El precedent més rellevant d’aquesta iconografia manual és la mà guidoniana, en l’àmbit musical, juntament amb …

Review of the volume that is configured as an essay on the declamatory phenomenon as a whole, but above all as a reading entirely internal to the first corpus of declamatory texts by Seneca il Vecchio that has come down to us
Prácticas de alto rendimiento : un enfoque configuracional aplicado al caso español
2008
Roberto.Luna@uv.es Joaquin.Camps@uv.es El principal objetivo de esta investigación es analizar diferentes configuraciones de prácticas de recursos humanos (RH) que se dan en una muestra de 183 empresas españolas. A continuación se relacionan estas configuraciones con las estrategias competitivas de las empresas con el fin de validar la estructura configuracional obtenida. Los resultados muestran tres tipos de configuraciones. La primera, empresas con prácticas de alto rendimiento (PAR) (37,5%), se caracteriza por un intenso y generalizado uso de dichas prácticas. La segunda, empresas desarrollando PAR (46,4%), se caracteriza por el uso de una amplia gama de PAR, pero con una limitada aplica…
