ROMANIAN RURAL DEVELOPMENT AND THE FINANCING POLICY
Romania has a large rural areas and a great potential, but the Romanian rural has many economic and social issues. The main idea is that the major risk for the Romanian rural development is generated of the combination between the transition problems, poverty and financing possibilities. For Romania is a need for benchmarking rural development and Romania looks at European Union and United States policy and programme. In Romania there is a vicious circle regarding the correlation between productivity and poverty. Because the poverty is a huge problem for Romanian rural areas, an essential problem is the access to the community funds. Important is the chain of the European structural funds financing: Allocation, Accession, and Absorption. One single error on every part of this chain would stop the investment. All insist that Romania should reform its administration and reduce red tape, to create a depoliticized and transparent system.rural development, financing, structural funds
Multilinear Wavelets: A Statistical Shape Space for Human Faces
We present a statistical model for D human faces in varying expression,
which decomposes the surface of the face using a wavelet transform, and learns
many localized, decorrelated multilinear models on the resulting coefficients.
Using this model we are able to reconstruct faces from noisy and occluded D
face scans, and facial motion sequences. Accurate reconstruction of face shape
is important for applications such as tele-presence and gaming. The localized
and multi-scale nature of our model allows for recovery of fine-scale detail
while retaining robustness to severe noise and occlusion, and is
computationally efficient and scalable. We validate these properties
experimentally on challenging data in the form of static scans and motion
sequences. We show that in comparison to a global multilinear model, our model
better preserves fine detail and is computationally faster, while in comparison
to a localized PCA model, our model better handles variation in expression, is
faster, and allows us to fix identity parameters for a given subject.Comment: 10 pages, 7 figures; accepted to ECCV 201
Novel pendant azobenzene/polymer systems for second harmonic generation and optical data storage
New poly(methyl methacrylate)s bearing push–pull azo-moieties, with the azo-dye content ranging from 31 wt% to 100 wt%, are synthesized by (co)polymerization of a methacrylamide-based azo-monomer. The high reactivity of the colored monomer allowed well-balanced structures to be achieved, characterized by a suitable thermal stability. The second harmonic generation efficiency of the poled samples is investigated by means of the SHG Maker fringes setup. Features that hinder the translation of the azo-moiety optical nonlinearity in the material at the macroscopic level are debated. The results underline the role of chromophore–chromophore and chromophore–polymer interactions on the alignment of the azo-moieties. The polarity of the polymer matrix is proven to influence the chromophore–chromophore interactions. Two-photon absorption is employed for gray scale encoding of second harmonic signals on poled thin films, thus pointing out the possibility to employ these new materials for optical data storage applications.
Translation Representations and Scattering By Two Intervals
Studying unitary one-parameter groups in Hilbert space (U(t),H), we show that
a model for obstacle scattering can be built, up to unitary equivalence, with
the use of translation representations for L2-functions in the complement of
two finite and disjoint intervals.
The model encompasses a family of systems (U (t), H). For each, we obtain a
detailed spectral representation, and we compute the scattering operator, and
scattering matrix. We illustrate our results in the Lax-Phillips model where (U
(t), H) represents an acoustic wave equation in an exterior domain; and in
quantum tunneling for dynamics of quantum states
The church of San Marco in the eleventh century
In 1084 the most important of the few consecrations of St Mark's church in Venice - that which solemnized the completion of its largest altar - took place. It is assumed that Doge Dominico Selvo (1071-1084) assigned Byzantine mosaicists to finish the decorative programme in time for the respective event. In part because of the beauty and the remarkable quality of the works they created, the eleventh century saw the prestige of this Venetian shrine increase. Also what in the popular imagination was the miraculous appearance of the relics of its patron saint from a pillar (either in 1084 or 1094, depending on the source employed) further augmented it. The article attempts to prove that the eleventh century was the most important period in the existence of the medieval Venetian church which much later became the cathedral San Marco. It will venture a description of this shrine not only on the basis of its similarities, claimed by most scholars, with the Apostoleion church in Constantinople, but also using information from extant documents as well as results of new scientific and archaeological discoveries, especially those published in the catalogue of the exhibition organised by its Procuratoria between July and November 2011, in Ken Dark and Ferudun Özgümüş's works, in the reports concerning the research undertaken by the British Museum, and in other sources.En 1084 tuvo lugar la más importante de las pocas consagraciones de la iglesia de San Marcos en Venecia, la que solemnizó la finalización de su altar mayor. Se supone que el dogo Dominico Selvo (1071-1084) encargó mosaicos bizantinos para terminar el programa decorativo a tiempo para el evento respectivo. En parte debido a la belleza y la notable calidad de las obras que crearon, el siglo XI vio aumentar el prestigio de este santuario veneciano. También lo que en el imaginario popular fue la aparición milagrosa de las reliquias de su santo patrón en un pilar (ya sea en 1084 o en 1094, según la fuente empleada) lo aumentó aún más. El artículo intenta demostrar que el siglo XI fue el período más importante en la existencia de la iglesia medieval veneciana, que mucho más tarde se convirtió en la catedral de San Marco. Se venturará una descripción de este santuario no solo sobre la base de sus similitudes, afirmadas por la mayoría de los eruditos, con la iglesia Apostoleion en Constantinopla, sino también utilizando información de documentos existentes, así como los resultados de nuevos descubrimientos científicos y arqueológicos, especialmente los publicados. en el catálogo de la exposición organizada por su Procuratoria entre julio y noviembre de 2011, en las obras de Ken Dark y Ferudun Özgümüş, en los informes sobre la investigación realizada por el Museo Británico, y en otras fuentes
The epektasis [ἐπέκτασις] and the exploits of the soul (ἡψυχή) in Gregory of Nyssa's De anima et resurrectione
The paper refers to a notion central to Gregory of Nyssa's theology -that of epektasis(ἐπέkτασις), i.e. progression of the soul (ἡψυχή) towards its Creator, as presented in the dialogue De anima et resurrectione/On the Soul and the Resurrection. The conversation between Nyssen and his sister Macrina, employing concepts peculiar to the most advanced science of their time, emphasizes that in the afterlife the soul does not leave the body (and neither does human memory). The interesting consequences of this state of affairs for both the resurrection of people and that of Jesus Christ are also discussed.El artículo se refiere a una noción central de la teología de Gregorio de Nisa: la de epektasis(ἐπέkτασις), es decir, la progresión del alma (ἡψυχή) hacia su Creador, como se presenta en el diálogo De anima et resurrectione/Sobre el alma y la resurrección. La conversación entre Nissa ysu hermana Macrina, empleando conceptos propios de la ciencia más avanzada de su tiempo, enfatiza que en el más allá el alma no abandona el cuerpo (tampoco la memoria humana). También se discuten las interesantes consecuencias de este estado de cosas tanto para la resurrección de las personas como para la de Jesús Cristo
Interaction of Co(II), Ni(II) and Cu(II) with dibenzo-substituted macrocyclic ligands incorporating both symmetrically and unsymmetrically arranged N, O and S donors
The synthesis and characterisation of four 17-membered, dibenzo-substituted macrocyclic ligands incorporating unsymmetrical arrangements of their N3S2, N3O2 and N3OS (two ligands) donor atoms are described; these rings complete the matrix of related macrocyclic systems incorporating both symmetric and unsymmetric donor sets reported previously. The X-ray structures of three of the new macrocycles are reported. In two of the Cu(II) structures only three of the possible five donor atoms present in the corresponding macrocyclic ligand bind to the Cu(II) site, whereas all five donors are coordinated in each of the remaining complexes. The interaction of Co(II), Ni(II) and Cu(II) with the unsymmetric macrocycle series has been investigated by potentiometric (pH) titration in 95% methanol; X-ray structures of two nickel and three copper complexes of these ligands, each exhibiting 1 : 1 (M :L) ratios, have been obtained. The results are discussed in the context of previous results for these metals with the analogous 17-membered ring systems incorporating symmetrical arrangements of their donor atoms, with emphasis being given to both the influence of the donor atom set, as well as the donor atom sequence, on the nature of the resulting complexes
Operator theory and function theory in Drury-Arveson space and its quotients
The Drury-Arveson space , also known as symmetric Fock space or the
-shift space, is a Hilbert function space that has a natural -tuple of
operators acting on it, which gives it the structure of a Hilbert module. This
survey aims to introduce the Drury-Arveson space, to give a panoramic view of
the main operator theoretic and function theoretic aspects of this space, and
to describe the universal role that it plays in multivariable operator theory
and in Pick interpolation theory.Comment: Final version (to appear in Handbook of Operator Theory); 42 page

The problem of forming a “dream” team involves many variables, including consideration of human factors and it is not a dilemma solvable in a mathematical way. Empirical studies might provide interesting insights to explain which factors need to be taken into account in building a team of developers and which levers act to optimise productivity among developers. Aim In this paper, we present the results of an empirical study aimed at investigating the link between team diversity (i.e., gender, nationality) and productivity (issue fixing time). Method We consider issues solved from the GHTorrent dataset inferring gender and nationality of each team’s members. We also evaluate the politeness of all comments involved in issue resolution. Results Results show that higher gender diversity is linked with a lower team average issue fixing time (higher productivity), that nationality diversity is linked with lower team politeness and that gender diversity is linked with higher sentiment.Peer reviewedFinal Published versio
