Ultrametricity property of energy landscapes of multidisperse packing problems
2009
We consider the problem of finding the densest closed packing of hard disks with proposed different radii in a circular environment, such that the radius of the circumcircle is minimal. The subspace of the quasioptimum configurations of this problem exhibits the property of ultrametricity.
Solution of the Lindblad equation in Kraus representation
2006
The so-called Lindblad equation, a typical master equation describing the dissipative quantum dynamics, is shown to be solvable for finite-level systems in a compact form without resort to writing it down as a set of equations among matrix elements. The solution is then naturally given in an operator form, known as the Kraus representation. Following a few simple examples, the general applicability of the method is clarified.
Extensive sampling sheds light on species-level diversity in Palearctic Placobdella (Annelida: Clitellata: Glossiphoniiformes)
2022
The bloodfeeding leech genus Placobdella is dominated by North American diversity, with only a single nominal species known from Central America and one from the Palearctic region. This is likely due to considerable underestimation of Palearctic biodiversity, but investigations into potential hidden diversity are lacking. To shed light on this, the present study introduces new data for specimens initially identified as Placobdella costata from Ukraine (close to the type locality), Italy, Germany, Latvia, Montenegro, Bulgaria, Slovenia, Turkey, Azerbaijan, Tunisia, and Algeria, and uses both nuclear (Internal Transcribed Spacer [ITS] region) and mitochondrial (cytochrome c oxidase subunit I …
A Glimpse over the Rising Walls
2009
The authors focus on societal perceptions of the Polish post-communist transformation as reflected in the rising discourse of gated communities. Guarded, (video-) controlled and/or walled housing estates have been on the sprawl in the Polish metropolises throughout the 1990s and 2000s. However, only recently they have been discursively constructed—under the banner of “gated communities”—as a social and political issue in the country. The authors look at this issue from a vantage point offered by Laclau and Mouffe's theory of discourse, which allows the authors to combine a spatial and a linguistic analytical perspective. The analysis emphasizes the manner in which societal perceptions of b…
Saying the Saffu and Beating the Law: The Changing Role of Sacred Sites in the Oromo Politico-Juridical System
2013
This chapter presents a semiotic analysis of the role of sacred sites and other physical features and objects in key political/religious rituals of the Oromo people living in the Horn of Africa. Theoretically, it builds on Jacques Derrida’s deconstruction of the concept of ‘archive’ as an intersection of the topological and the nomological of the place and the law. For Derrida, the place of the archive is not a locatable place, but a topos, the marking of a discourse. In contrast to the European tradition based primarily on archives inscribed in writing and summarised in a codified law, for the traditional Oromo society, laws were part of the oral tradition – a mixture of religion, law and …
Caracterización de la suplementación de folatos en el embarazo a partir de la combinación de sistemas de información sanitaria.
2012
ResumenObjetivosExplorar la utilidad de la combinación de los sistemas de información sanitaria de la Agencia Valenciana de Salud (AVS) para caracterizar la suplementación de folatos en la población de embarazadas de la Comunidad Valenciana.MétodosCohorte de todas las mujeres que parieron en hospitales de la AVS durante 2009, que fueron seguidas retrospectivamente en la historia clínica electrónica ABUCASIS y el sistema GAIA de gestión de la prescripción para identificar el consumo de folatos en los 3 meses previos y posteriores a la concepción.ResultadosDe los 38.069 partos realizados en 2009 en hospitales de la AVS, 37.040 (97,3%) pudieron incluirse en los análisis. Un 34,0% de las mujere…
Bounds for the first Dirichlet eigenvalue attained at an infinite family of Riemannian manifolds
1996
LetM be a compact Riemannian manifold with smooth boundary ∂M. We get bounds for the first eigenvalue of the Dirichlet eigenvalue problem onM in terms of bounds of the sectional curvature ofM and the normal curvatures of ∂M. We discuss the equality, which is attained precisely on certain model spaces defined by J. H. Eschenburg. We also get analog results for Kahler manifolds. We show how the same technique gives comparison theorems for the quotient volume(P)/volume(M),M being a compact Riemannian or Kahler manifold andP being a compact real hypersurface ofM.
The Configuration of Space Through Architecture in the Thinking of Gadamer
2017
Although Gadamer stresses the importance of temporality, historicity and tradition, the aim of this contribution is to underline the uniqueness of architecture in Truth and Methods’ investigation relative to the essence of a work of art. The uniqueness of architecture for Gadamer lies not only in the fact that it gives space for the expression of all other kinds of artworks; a building has to be to understood as self-sufficient and as autarchic, but also as inscribed in the concrete historical life. A further aspect of the uniqueness of architecture originates in the fact that a building determines our way of life or our dwelling even in a political sense.
Molecular barcoding for central-eastern European Crioceris leaf-beetles (Coleoptera: Chrysomelidae)
2011
Abstract Among Crioceris leaf-beetles, the two most widespread species (Crioceris asparagi and C. duodecimpunctata) are serious invasive plant pests, while another two (C. quatuordecimpunctata and C. quinquepunctata) are rare species restricted to steppe-like habitats in Eurasia. The aim of the research was to check the genetic distinctiveness of these four species and develop barcodes for their molecular identification using the mitochondrial Cytochrome Oxidase I (COI) gene and two nuclear markers: Elongation Factor 1-α (EF1-α) and Internal Transcribed Spacer 1 (ITS1). The identification of each species was possible and reliable with the use of COI and ITS1 markers. EF1-α was omitted in an…
Providing QOS in 3G-WLAN environment with RSVP and DIFFSERV
2006
Here we present the end-to-end QoS mechanism in 3G-multiaccess network environment. As multi-access wireless WLAN and wired xDSL wideband multi-access technologies has emerge and become more popular a need for interoperability with different technologies and domains has become necessity. There is also a need for end-to-end QoS management. We show a scenario where the UE-GGSN connection is covered by RSVP and RAN network part uses partial over dimensioning and real-time controlled ATM queuing. DiffServ covers WLAN-Core QoS and radio interface between WLAN AP and WLAN UE uses IEEE's 802.11e. Our interest is to find out how well 3G traffic classes can survive in different traffic conditions in…
