2016

We describe completely the link invariants constructed using Markov traces on the Yokonuma-Hecke algebras in terms of the linking matrix and the HOMFLYPT polynomials of sublinks.

Radioloģijas metožu pielietojums kriminālistikā

2022

Bakalaura darba tēma – “Radioloģijas metožu pielietojums kriminālistikā”. Tēmas aktualitāti nosaka tas, ka Latvijā vērojams otrs augstākais vardarbīgo nāves gadījumu skaits un visaugstākais slepkavības gadījumu skaits ES. Būtiski, ka aptuveni desmitajai daļai mirušo nāves cēlonis netiek noteikts, sestā daļa slepkavību netiek atklātas, augsta ir arī tiesu medicīnas ekspertu noslodze. Rodas jautājums, kā ir iespējams padarīt optimālāku tiesu medicīniskās izpētes un ekspertīžu veikšanu, un kā var paaugstināt to precizitāti, rezultativitāti. Darba mērķis - aprakstīt radioloģijas metodes kriminālistikā, izpētīt, kura no tām ir efektīvākā. Pētījuma jautājums: kura no radioloģijas metodēm krimināl…

Therapeutic effects of hMAPC and hMSC transplantation after stroke in mice.

2012

Stroke represents an attractive target for stem cell therapy. Although different types of cells have been employed in animal models, a direct comparison between cell sources has not been performed. The aim of our study was to assess the effect of human multipotent adult progenitor cells (hMAPCs) and human mesenchymal stem cells (hMSCs) on endogenous neurogenesis, angiogenesis and inflammation following stroke. BALB/Ca-RAG 2(-/-) γC(-/-) mice subjected to FeCl(3) thrombosis mediated stroke were intracranially injected with 2 × 10(5) hMAPCs or hMSCs 2 days after stroke and followed for up to 28 days. We could not detect long-term engraftment of either cell population. However, in comparison w…

Impact of intravascular enhancement, heart rate, and calcium score on diagnostic accuracy in multislice computed tomography coronary angiography.

2005

PURPOSE: To assess the effect of intravascular enhancement, heart rate, and calcium score on diagnostic accuracy in the detection of significant coronary artery stenosis using 16-row multislice computed tomography (MSCT). MATERIALS AND METHODS: One hundred patients (88 males; 59+/-11 years) with suspected coronary artery disease who had undergone conventional coronary angiography (CA) and MSCT-CA were retrospectively enrolled for the study. Patients underwent a MSCT-CA, with the following protocol: collimation 16x0.75 mm, gantry rotation time 420 ms, feed/rotation 2.8 mm, kV 120, mAs 400-500. The protocol for contrast material administration was 100 ml of Iodixanol 320 mgI/ml at 4 ml/s and …

A Gramsci Renaissance?

2022

In this article, some recent pedagogical studies about Gramsci’s philosophy of praxis will be analyzed. Starting from these studies, the author ar-gues for the possibility of reading the contemporaneity through Gram-scian lens. In particular, he puts forward the hypothesis of using category of passive revolution to decipher the neoliberal reforms of the (Italian) school system.

Subalternità e filosofia della storia. Appunti sul carteggio Marx-Zasulič

2021

this article proposes, through the Gramscian political-pedagogical category of subalternity, a reading of the brief exchange of letters at the beginning of 1881 between Karl Marx and Vera Zasulič, a russian revolutionary militant at that time member of the populist group Čërnyj peredel (black repartition), on an issue of great importance for the russian socialist movement: the obščina, or that specific form of common ownership of land by russian peasants. to this end, it is necessary to analyze the chapter XXiV of the first book of Capital, in which Marx outlines the historical genesis of capitalism in Western europe and, in particular, in england, through the phenomenon of «the so-called o…

Interior eigenvalue density of large bi-diagonal matrices subject to random perturbations

2017

We study the spectrum of large a bi-diagonal Toeplitz matrix subject to a Gaussian random perturbation with a small coupling constant. We obtain a precise asymptotic description of the average density of eigenvalues in the interior of the convex hull of the range symbol.

Dimensional reduction for energies with linear growth involving the bending moment

2008

A $\Gamma$-convergence analysis is used to perform a 3D-2D dimension reduction of variational problems with linear growth. The adopted scaling gives rise to a nonlinear membrane model which, because of the presence of higher order external loadings inducing a bending moment, may depend on the average in the transverse direction of a Cosserat vector field, as well as on the deformation of the mid-plane. The assumption of linear growth on the energy leads to an asymptotic analysis in the spaces of measures and of functions with bounded variation.

Normal forms and embeddings for power-log transseries

2016

First return maps in the neighborhood of hyperbolic polycycles have their asymptotic expansion as Dulac series, which are series with power-logarithm monomials. We extend the class of Dulac series to an algebra of power-logarithm transseries. Inside this new algebra, we provide formal normal forms of power-log transseries and a formal embedding theorem. The questions of classifications and of embeddings of germs into flows of vector fields are common problems in dynamical systems. Aside from that, our motivation for this work comes from fractal analysis of orbits of first return maps around hyperbolic polycycles. This is a joint work with Pavao Mardešić, Jean-Philippe Rolin and Vesna Župano…
