Uniqueness of diffusion on domains with rough boundaries
2016
Let $\Omega$ be a domain in $\mathbf R^d$ and $h(\varphi)=\sum^d_{k,l=1}(\partial_k\varphi, c_{kl}\partial_l\varphi)$ a quadratic form on $L_2(\Omega)$ with domain $C_c^\infty(\Omega)$ where the $c_{kl}$ are real symmetric $L_\infty(\Omega)$-functions with $C(x)=(c_{kl}(x))>0$ for almost all $x\in \Omega$. Further assume there are $a, \delta>0$ such that $a^{-1}d_\Gamma^{\delta}\,I\le C\le a\,d_\Gamma^{\delta}\,I$ for $d_\Gamma\le 1$ where $d_\Gamma$ is the Euclidean distance to the boundary $\Gamma$ of $\Omega$. We assume that $\Gamma$ is Ahlfors $s$-regular and if $s$, the Hausdorff dimension of $\Gamma$, is larger or equal to $d-1$ we also assume a mild uniformity property for $\Omega$ i…
An initial comparative map of copy number variations in the goat (Capra hircus) genome
2010
Abstract Background The goat (Capra hircus) represents one of the most important farm animal species. It is reared in all continents with an estimated world population of about 800 million of animals. Despite its importance, studies on the goat genome are still in their infancy compared to those in other farm animal species. Comparative mapping between cattle and goat showed only a few rearrangements in agreement with the similarity of chromosome banding. We carried out a cross species cattle-goat array comparative genome hybridization (aCGH) experiment in order to identify copy number variations (CNVs) in the goat genome analysing animals of different breeds (Saanen, Camosciata delle Alpi,…
New evidence on accelerator performance based on funding and location
2020
Seed accelerators (SAs) appear as a more advanced version of business incubators. These for-profit organizations in exchange of equity, help setting new start-ups by providing mentoring and funding during its first months. Due to their emergent nature, the impact and expectations of SAs remains largely unknown. Therefore, the purpose of this study is to throw new light on this field by empirically assessing for the first time the performance and prospects of these organizations through a survey of 116 SAs.,A model based on the Business Incubators literature is built with four categories covering size, location, age and profitability variables, leading to two hypotheses to be tested empirica…
El efecto mediador y moderador de la internacionalización en la relación entre los sistemas de control de gestión y el compromiso con la innovación
2019
La literatura contable revela resultados contradictorios al evaluar el efecto que los diferentes usos de los sistemas de control de gestión (SCG) tienen en la innovación. Siguiendo el marco teórico establecido por Simons (1995), este trabajo prueba el efecto que la internacionalización, bien sea directo, mediador o moderador, tiene en la relación entre el uso interactivo de los SCG y el compromiso de las empresas con la innovación. Tomando una muestra de 231 organizaciones del sector agroalimentario español, los resultados obtenidos ponen de manifiesto la ausencia de una relación directa entre el uso interactivo del conjunto de herramientas de SCG y el compromiso con la innovación. Del mism…

7C: Computational Chromosome Conformation Capture by Correlation of ChIP-seq at CTCF motifs.
2019
Abstract Background Knowledge of the three-dimensional structure of the genome is necessary to understand how gene expression is regulated. Recent experimental techniques such as Hi-C or ChIA-PET measure long-range chromatin interactions genome-wide but are experimentally elaborate, have limited resolution and such data is only available for a limited number of cell types and tissues. Results While ChIP-seq was not designed to detect chromatin interactions, the formaldehyde treatment in the ChIP-seq protocol cross-links proteins with each other and with DNA. Consequently, also regions that are not directly bound by the targeted TF but interact with the binding site via chromatin looping are…
Nanodaļiņu nogādāšana uz audzēju šūnām mezenhimālo cilmes šūnu un MDA-MB-231 šūnu 3D kopkultūras modelī
2016
Nanodaļiņas tiek uzskatītas par potenciālām transporta molekulām, kuras varētu nogādāt pretvēža zāles tieši uz audzēju šūnām. Bakalaura darba mērķis bija analizēt vai notiek nanodaļiņu pārnese uz audzēja šūnām mezinhimālo cilmes šūnu un MDA-MB-231 šūnu 3D kopkultūru modelī. Abas šūnu kultūras tika kultivēts S10 barotnē. Šūnu kultūru diferenciēšanai tika izvēlēts CD90 marķieris. MCŠ tika iezīmētas ar QD655 un pēc 6h inkubācijas tika veikta plūsmas citometrijas analīze. 3D kopkultūras modelis tika izveidots izmantojot PolyHEMA pārklājumu. QD pārnese uz vēža šūnām tika analizēta ar plūsmas citometriju pēc 48h kultivēšanas 3D kopkultūras modelī. 97% MCŠ 2D kultūrā pēc 6h inkubācijas uzņem QD655…
Field Oriented Control of IPMSM Fed by Multilevel Cascaded H-Bridges Inverter with NI-SOM sbRIO-9651 FPGA controller
2022
Electrical drives fed by Multilevel Inverters (MIs) are of considerable interest for traction and e-mobility applications. In detail, Cascaded H-Bridge Multilevel Inverter (CHBMI) is a promising solution for electrical drive optimization purposes in terms of efficiency, safety, integration and flexible use of energy sources. The aim of this paper is the experimental implementation of the field-oriented control strategy of Interior Permanent Magnet Synchronous Machine (IPMSM) fed by CHBMI by use of NI-SOM sbrRIO-9651 FPGA controller. This FPGA controller can be programmable in the LabVIEW programming environment with the consequent benefits of graphical programming. The paper address the acq…
Synthesis and studies of new optimised chelating agents for targeting chemokine receptor CXCR4
2012
The objective of this thesis work was to develop CXCR4-targeted tools to localize and treat cancer at an early stage. In this line, we investigated the synthesis of new target-specific radiopharmaceuticals. The work focused on two main axes, i.e. the chelating agent and the carrier, by using the know-how and the expertise of our group in polyazacycloalkanes synthesis and functionalization. In the first part, we were interested in developing new macrocyclic scaffolds of high potential for copper and gallium chelation. We first focused on the development of a new powerful route towards selectively functionalized constrained homocyclens. The second part was based on C-functionalized 1,4,7-tria…
