Valoración de los parámetros inflamatorios como factores de riesgo independiente para supervivencia en los pacientes con cáncer de pulmón no microcít…
2021
Antecedentes: El cáncer de pulmón sigue siendo la causa principal de muerte por cáncer en nuestro medio. En concreto, el cáncer de pulmón no microcítico (CPNM) supone un 80% de los casos y el pronóstico, incluso en enfermedad localmente avanzada sigue siendo pobre, con una supervivencia en torno al 20% en estadio III. Además, la enfermedad localmente avanzada supone un subgrupo heterogéneo, en el que las opciones terapéuticas y la evolución pueden ser muy dispares, y puede incluir tanto la cirugía, como el tratamiento con quimiorradioterapia (QRT), con o sin tratamiento de mantenimiento con inmunoterapia, y el tratamiento paliativo. En este escenario cobra especial importancia la búsqueda d…
Improved chemometric approach for XRF data treatment: application to the reverse glass paintings from the Lipari collection
2023
The Aeolian cultural heritage preserves hundreds of testimonies of the past that have passed through six millennia of history. Among these, the Archeological Park of the Aeolian Islands with the Museum Luigi Bernab`o Brea (Italy) preserves a valuable set of artworks, which are related to a little-known ‘popular’ figurative heritage. It is an assemblage of small glass foils decorated using the technique of reverse painting, datable to between the end of the 17th century and the end of the 18th century, and actually under investigation by historians. Here, an X-ray fluorescence (XRF) spectroscopy study (performed with portable equipment) is combined with a multivariate approach that allows us…
Photoluminescent Detection of Human T-Lymphoblastic Cells by ZnO Nanorods.
2020
The precise detection of cancer cells currently remains a global challenge. One-dimensional (1D) semiconductor nanostructures (e.g., ZnO nanorods) have attracted attention due to their potential use in cancer biosensors. In the current study, it was demonstrated that the possibility of a photoluminescent detection of human leukemic T-cells by using a zinc oxide nanorods (ZnO NRs) platform. Monoclonal antibodies (MABs) anti-CD5 against a cluster of differentiation (CD) proteins on the pathologic cell surface have been used as a bioselective layer on the ZnO surface. The optimal concentration of the protein anti-CD5 to form an effective bioselective layer on the ZnO NRs surface was selected. …

Fibre fragment distribution in a single-fibre composite tension test
2001
Abstract Single fibre fragmentation tests are performed for brittle fibres with Weibull strength distribution and different surface treatments. The fragmentation process is modelled and closed-form expressions for break spacing distribution are obtained. The model accounts for the effect of finite fibre length on the initial fragmentation as well as for break interaction on the advanced fragmentation stage. It is assumed that the exclusion zone due to fibre–matrix interface failure and stress recovery in the fibre is linearly dependent on the applied load. This assumption is validated experimentally. The derived theoretical average fragment length dependence on applied load is used to deter…
One-loop corrections to light cone wave functions: the dipole picture DIS cross section
2018
We develop methods needed to perform loop calculations in light cone perturbation theory using a helicity basis, refining the method introduced in our earlier work. In particular this includes implementing a consistent way to contract the four-dimensional tensor structures from the helicity vectors with d-dimensional tensors arising from loop integrals, in a way that can be fully automatized. We demonstrate this explicitly by calculating the one-loop correction to the virtual photon to quark-antiquark dipole light cone wave function. This allows us to calculate the deep inelastic scattering cross section in the dipole formalism to next-to-leading order accuracy. Our results, obtained using …
Development of microfluidics for sorting of carbon nanotubes
2018
Sorting of carbon nanotubes by their chirality is the current bottleneck in the way to their broad employment based on their exceptional electronic and optical properties. Despite the extensive effort, there is no known method, which would result in really pure chirality ensembles. Previously reported sorting protocols result in enrichment rather than in sorting, alter electronic structure, and suffer from low yield. This is mostly due to the statistical approach, where the nanotubes with mixed chiralities are treated as a set. In this thesis, we propose a new sorting technique based on nanotube-by-nanotube compartmelization, characterization, and sorting in a continuously running droplet-b…

Stikla pakešu konstruktīvo parametru automatizēta noteikšana
2021
Maģistra darba mērķis ir izstrādāt programmatūru, kas pēc ievades datiem spēj būvinženierim parādīt vairākus iespējamos stikla paketes uzbūves variantus, kas atbilst konstruktīvajām prasībām normatīvos. Darbā implementēti vadlīnijās aprakstīti vienkāršojumi, lai izveidotu ātri aprēķināmus galīgo elementu modeļus. Uz ~2 miljonu galīgo elementu modeļu aprēķinu bāzes ir trenēti neironu tīklu “surogāta modeļi”. Iegūta >98% precizitāte, izmantojot Google piedāvātu automatizētu mašīnmācīšanās risinājumu. Izveidotie neironu tīklu modeļi sasniedz ~160-kārtīgu ātruma palielinājumu salīdzinot ar galīgo elementu aprēķiniem, vienu pilnu stiklu paketes izvērtējumu paātrinot līdz ~300 milisekundēm. Šāds …
