description: Os sistemas de visão permitem obter informações sobre o comportamento de estrutural de forma eficiente, sendo aplicados para extrair informações estruturais relevantes, p.e., deslocamentos e deformações em secções críticas. Este artigo introduz uma metodologia para a monitorização de ensaios dinâmicos utilizando visão por computador. A abordagem permite seguir alvos artificiais, com cor e geometria selecionada para otimizar a sua deteção, colocados em secções predefinidas – ‘alvos móveis’, e na mesa sísmica de ensaio – ‘alvos de controlo’. São captadas imagens durante os ensaios, nas quais são detetadas as coordenadas dos centros dos alvos. Posteriormente, os deslocamentos são calculados com base nas diferenças de coordenadas entre os alvos referidos nos vários instantes. Para calibrar a metodologia foram monitorizados ensaios num modelo reduzido imprimido em ABS. Posteriormente, a metodologia foi validada no ensaio de um modelo reduzido de uma casca de betão. Os resultados demonstram a capacidade da metodologia desenvolvida na monitorização de ensaios dinâmicos, permitindo o acompanhamento contínuo de alvos colocados na estrutura.
description: Vision systems enable efficient extraction of structural behavior information, applied to obtain relevant data such as displacements and deformations in critical sections. This paper introduces a methodology for monitoring dynamic tests using computer vision. The approach allows tracking artificial targets, with color and geometry selected to optimize their detection, placed in predefined sections – 'mobile targets' – and on the shaking table during testing – 'control targets'. Images are captured during the tests, in which the coordinates of the target centers are detected. Afterwards, displacements are calculated based on the coordinate differences between the targets at different instants. To calibrate the methodology, tests were monitored on a reduced-scale model printed in ABS. Later, the methodology was validated in the testing of a scaled model of a concrete shell. The results demonstrate the capability of the developed methodology in monitoring dynamic tests, enabling continuous tracking of targets placed on the structure.

description: The hard-disk problem, the statics and the dynamics of equal two-dimensional hard spheres in a periodic box, has had a profound influence on statistical and computational physics. Markov-chain Monte Carlo and molecular dynamics were first discussed for this model. Here we reformulate hard-disk Monte Carlo algorithms in terms of another classic problem, namely the sampling from a polytope. Local Markov-chain Monte Carlo, as proposed by Metropolis et al. in 1953, appears as a sequence of random walks in high-dimensional polytopes, while the moves of the more powerful event-chain algorithm correspond to molecular dynamics evolution. We determine the convergence properties of Monte Carlo methods in a special invariant polytope associated with hard-disk configurations, and the implications for convergence of hard-disk sampling. Finally, we discuss parallelization strategies for event-chain Monte Carlo and present results for a multicore implementation.

description: In this project, I worked to genetically manipulate the tardigrade species Hypsibius exemplaris as a means towards developing viable transgenic tardigrades. By observing the eye pigmentation pathways in the related organism Drosophila melanogaster and finding homologs of the involved genes in Hypsibius, I developed a list of target genes for RNA interference. I designed primers for the target genes, amplified them by PCR, and translated them to make dsRNAs, which were then injected into the adult tardigrade. Offspring of injected adults were observed for loss of eye pigments. This project also involved experiments to incorporate mRNA into the the body cavity of an injected adult tardigrade.

description: $UBVRI$ photometry of the five open clusters Czernik 4, Berkeley 7, NGC 2236, NGC 7226 and King 12 has been carried out using ARIES 104 cm telescope, Nainital. Fundamental cluster parameters such as foreground reddening $E(B-V)$, distance, and age have been derived by means of the observed two colour and colour-magnitude diagrams, coupled to comparisons with theoretical models. $E(B-V)$ values range from 0.55 to 0.74 mag, while ages derived for these clusters range from $\sim$10 to $\sim$500 Myr. We have also studied the spatial structure, mass function and mass segregation effects. The present study shows that evaporation of low mass stars from the halo of the clusters increases as they evolve.

description: We present results of the instability analysis of the post-main sequence massive star models against radial and nonradial pulsations. We confirm that both p- and g-modes can be excited by the $κ$-mechanism acting in the metal opacity bump. However, as opposed to the previous claims, we find that an intermediate convective zone (ICZ) related to the hydrogen burning shell is not necessary for excitation of g-modes. These modes can be reflected at a minimum of the Brunt-Väisälä frequency, located at the top of the chemical composition gradient region surrounding the radiative helium core. This minimum is associated with the change of actual temperature gradient from the adiabatic value in the semiconvective zone to the radiative value above it. Thus, the existence of pulsations at this evolutionary stage does not prove the existence of the convective zone but only some reflective layer. Finally, we show that no regular patterns can be expected in oscillation spectra of blue supergiant pulsators but there is a prospect for identification of the mode degree, $\ell$, from multicolour photometry.

description: In this letter, we report on unipolar vertical transport characteristics in c-plane GaN/AlGaN/GaN heterostructures. Vertical current in heterostructures with random alloy barriers was found to be independent of dislocation density and heterostructure barrier height, and significantly higher than theoretical estimates. Percolation-based transport due to random alloy fluctuations in the ternary AlGaN is suggested as the dominant transport mechanism, and confirmed through experiments showing that non-random or digital AlGaN alloys and polarization-engineered binary GaN barriers can eliminate percolation transport and reduce leakage significantly. The understanding of vertical transport and methods for effective control proposed here will greatly impact III-nitride unipolar vertical devices.

description: We combine UV/Optical/near-IR/mid-IR data on a sample of ~240 S0 galaxies to examine various star formation related processes in them. We split the sample into bright and faint S0 galaxies based on their K band luminosity. Comparing the FUV-NUV versus NUV-K color-color diagram with a Simple Stellar Population (SSP) model shows that ellipticals and bright S0 galaxies are dominated by a stellar population of age > 10^9 years while faint S0 galaxies may contain stars as young as 10^8 years, providing evidence for relatively recent star formation activity. The strength of the 4000A break is also systematically higher in brighter S0 galaxies, again indicating the presence of an old stellar population. Their mid-IR colours indicate that bright S0 colours are like those of ellipticals while faint S0 colours are more like spirals. All these observations are consistent with a scenario in which low-luminosity S0 galaxies likely formed by the stripping of gas from the discs of late-type spiral galaxies, which in turn formed their pseudo bulges through secular evolution processes, possibly involving multiple episodes of star formation. On the other hand, more luminous S0 galaxies likely formed the bulk of their stars at early epochs, similar to the star formation in elliptical galaxies, and are characterised by an old coeval stellar population and classical bulge

description: In this paper we apply a Bayesian framework to the problem of geodesic curve matching. Given a template curve, the geodesic equations provide a mapping from initial conditions for the conjugate momentum onto topologically equivalent shapes. Here, we aim to recover the well-defined posterior distribution on the initial momentum which gives rise to observed points on the target curve; this is achieved by explicitly including a reparameterisation in the formulation. Appropriate priors are chosen for the functions which together determine this field and the positions of the observation points, the initial momentum $p_0$ and the reparameterisation vector field $ν$, informed by regularity results about the forward model. Having done this, we illustrate how Maximum Likelihood Estimators (MLEs) can be used to find regions of high posterior density, but also how we can apply recently developed \SLC{Markov chain Monte Carlo (MCMC)} methods on function spaces to characterise the whole of the posterior density. These illustrative examples also include scenarios where the posterior distribution is multimodal and irregular, leading us to the conclusion that knowledge of a state of global maximal posterior density does not always give us the whole picture, and full posterior sampling can give better quantification of likely states and the overall uncertainty inherent in the problem.

description: Este artigo apresenta (1) o processo adotado na produção industrial de um protótipo de uma casca ultrafina com dupla curvatura, constituída por módulos pré-fabricados em betão de ultraelevado desempenho (UHPC) e (2) a metodologia desenvolvida para a sua montagem e assemblagem in situ, com recurso a pré-esforço.
Face aos diferentes desafios impostos, nomeadamente (1) a forma de dupla curvatura, (2) a elevada esbelteza das peças, (3) as diminutas tolerâncias e o elevado rigor geométrico das ligações indentadas secas e (4) a localização precisa do traçado dos cordões de pré-esforço, decidiu adotar-se uma cofragem metálica e betonagem na direção vertical.
Foi especialmente desenvolvido um apoio com o objetivo de garantir a integridade estrutural da casca, servir de ancoragem aos cordões de pré-esforço e transmitir os esforços da casca para as fundações. Subsequentemente, todas as soluções (moldes, produção, montagem, apoios) foram validadas na construção de um modelo à escala reduzida (1:3).

description: This paper presents (1) the process adopted in the industrial production of an ultra-thin double curvature shell prototype, made of precast modules in ultra-high performance (UHPC) fiber-reinforced concrete, and (2) the methodology developed for assembling it on-site, using prestress, and fixing it to the supports.
To deal with all the challenges, namely (i) the double curvature shape, (ii) the ultra-thin thickness and the consequent high slenderness of the parts, (iii) the low tolerances and the high geometric accuracy of the indented dry connections, and (iv) the precise positioning of the prestressing strands layout, particularly relevant at the joints between parts, it was decided to adopt a metal formwork and concreting in the vertical direction.
A support was specially developed to ensure the structural integrity of the shell, serve as anchorage for the prestressing strands, and transfer forces from the shell to the foundation.
Subsequently, all solutions (molds, production, assembly, supports) were validated in a reduced model (1:3 scale).

description: Core-collapse supernovae emit on the order of 3x10^53 ergs in high-energy neutrinos over a time of order 10 seconds, and so decrease their mass by about 0.2 solar mass. If the explosion is nearly spherically symmetric, there will be little gravitational wave emission. Nevertheless, the sudden decrease of mass of the progenitor may cause a change in the gravitational time delay of signals from a nearby pulsar. We calculate the change in arrival times as successive pulses pass through the neutrino shell at different times, and find that the effect may be detectable in ideal circumstances.

description: Dispersal is a key process in ecology and evolutionary biology, as it shapes biodiversity patterns over space and time. Mounting evidence is showing that attitude to disperse is unevenly distributed among individuals within animal populations, and that individual personality can have pivotal roles in the shaping of this attitude. Here, we contribute to the study of the genetic underpinnings of dispersal-related behavioral variation by assembling and annotating the first de novo transcriptome of the head tissues of Salamandra salamandra. Although dispersal occurs mostly during the post-metamorphic terrestrial life stage in this species, variation in dispersal-related personality traits is already evident at the aquatic larval stage, making it an excellent candidate species for studies of carry-over effects. We employed a structured pipeline to de-novo assemble and annotate transcripts from RNA-Seq in a set of individuals representative of distinct behavioral profiles. We obtained 1,153,432,918 reads, which were successfully de novo assembled and annotated. The high-quality assembly was confirmed by comparing BUSCO, DETONATE and TransRate with the S. salamandra dataset. By aligning the contigs against the de novo transcriptome we obtained a percentage of mapping higher than 94%. The homology annotation performed with DIAMOND led to 153,048 (blastx) and 95,942 (blastp) shared contigs, annotated on NCBI nr, Swiss-Prot and TrEMBL. The domain and site protein prediction made with InterProScan led to 9850 GO-annotated contigs. This de-novo transcriptome represents reliable reference for whole transcriptome and proteome studies of other amphibians, for designing primers to clone specific genes or monitor their expression, and for analyzing comparative gene expression profiles between alternative behavioral types.

description: The energy spectra of galactic cosmic rays carry fundamental information regarding their origin and propagation. These spectra, when measured near Earth, are significantly affected by the solar magnetic field. A comprehensive description of the cosmic radiation must therefore include the transport and modulation of cosmic rays inside the heliosphere. During the end of the last decade the Sun underwent a peculiarly long quiet phase well suited to study modulation processes. In this paper we present proton spectra measured from July 2006 to December 2009 by PAMELA. The large collected statistics of protons allowed the time variation to be followed on a nearly monthly basis down to 400 MV. Data are compared with a state-of-the-art three-dimensional model of solar modulation.

description: Neste artigo apresenta-se um estudo numérico para analisar o efeito do pré-esforço em cascas ultrafinas pré-fabricadas em UHPC não armado. A forma da casca segue o antifunicular do peso próprio, sendo sensível a esforços de flexão provocados por ações não uniformes. Um traçado de cabos aderentes e pós-tensionados é proposto observadas as direções de tensões principais geradas pela combinação de ações mais desfavorável. A solução adotada melhora a capacidade de carga reduzindo significativamente as tensões de tração. Contudo, o seu efeito é limitado: a reduzida espessura da casca, a variabilidade de ações, e a consequente ausência de excentricidade dos cabos não permitem contributos significativos para a resistência à flexão. Adicionalmente, o préesforço gera tensões radiais indesejáveis que, embora de intensidade moderada, têm um carácter permanente. A adoção de um UHPC revela-se acertada, sugerindo-se o reforço com fibras para permitir reduzir a espessura, e/ou nível de pré-esforço instalado e melhorar a ductilidade.
description: This paper presents a numerical study to analyse the effects of prestress in ultra-thin precast UHPC shells. The shell's shape follows the anti-funicular of its self-weight, making it vulnerable to bending moments caused by non-uniform actions. A layout of adherent and post-tensioned cables is proposed, considering the principal stress directions resulting from the most unfavourable load combination. The results indicate that the adopted solution enhances the loadcarrying capacity by reducing tensile stresses. However, its effect is limited due to the shell's reduced thickness, loads variability, and the consequent absence of cable eccentricity, which limits the bending strength increase. Additionally, the prestress induces permanent and unwanted radial stresses of moderate intensity. The use of UHPC is deemed appropriate. Fibre reinforcement is suggested to further reduce thickness, lower the pre-stressing levels, and improve ductility.

description: В Ставропольском крае отмечаются региональные особенности изменения климата, которые оказывают влияние на продуктивность сельскохозяйственных культур. Выявление климатических показателей и оценка их значимости для получения высоких урожаев озимой пшеницы является важной практической задачей исследования. В результате установлено наличие достоверной корреляционной зависимости между урожайностью озимой пшеницы и температурой декабря, января, февраля и марта. Выявлена высокая доля влияния тепло- и влагообеспеченности октября, а также суммы осадков весенних месяцев. Отмечается сложность выявления отдельных периодов года, которые определяют урожайность озимой пшеницы, поскольку продукционный процесс является многофакторным.
description: In Stavropol Region regional features of climate change which have an impact on efficiency of crops are noted. Identifying climatic indicators and assessing their significance for obtaining high yields of winter wheat is an important practical task of the study. As a result, a reliable cor-relation was found between the yield of winter wheat and the temperature of December, Janu-ary, February and March. A high proportion of heat and moisture influence on October was re-vealed, as well as the amount of precipitation in the spring months. It is noted the difficulty of identifying individual periods of the year, which determine the yield of winter wheat, since the production process is multifactorial.

description: This paper presents a new approach for optimizing multitheaded programs with pointer constructs. The approach has applications in the area of certified code (proof-carrying code) where a justification or a proof for the correctness of each optimization is required. The optimization meant here is that of dead code elimination. Towards optimizing multithreaded programs the paper presents a new operational semantics for parallel constructs like join-fork constructs, parallel loops, and conditionally spawned threads. The paper also presents a novel type system for flow-sensitive pointer analysis of multithreaded programs. This type system is extended to obtain a new type system for live-variables analysis of multithreaded programs. The live-variables type system is extended to build the third novel type system, proposed in this paper, which carries the optimization of dead code elimination. The justification mentioned above takes the form of type derivation in our approach.

description: The method of Monte Carlo configuration interaction (MCCI) [1,2] is applied to the calculation of multipole moments. We look at the ground and excited state dipole moments in carbon monoxide. We then consider the dipole of NO, the quadrupole of the nitrogen molecule and of BH. An octupole of methane is also calculated. We consider experimental geometries and also stretched bonds. We show that these non-variational quantities may be found to relatively good accuracy when compared with FCI results, yet using only a small fraction of the full configuration interaction space. MCCI results in the aug-cc-pVDZ basis are seen to generally have reasonably good agreement with experiment. We also investigate the performance of MCCI when applied to ionisation energies and electron affinities of atoms in an aug-cc-pVQZ basis. We compare the MCCI results with full configuration-interaction quantum Monte Carlo [3,4] and `exact' non-relativistic results [3,4]. We show that MCCI could be a useful alternative for the calculation of atomic ionisation energies however electron affinities appear much more challenging for MCCI. Due to the small magnitude of the electron affinities their percentage errors can be high, but with regards to absolute errors MCCI performs similarly for ionisation energies and electron affinities.

description: Artykuł został napisany z myślą o analizie zjawiska autorytetu nauczyciela w Polskiej Rzeczypospolitej Ludowej, w szczególności relacji między założeniami a rzeczywistością. Wyniki wskazują i podkreślają tezę, że polityka edukacyjna nie wspierała procesu formowania się prawdziwego autorytetu nauczyciela. Oficjalne akty prawne i praktyczne szkolenia ideologiczne często zmuszały nauczycieli do pracy w niezgodzie ze swoim sumieniem i podważały ich autorytet w oczach ucznia. Z drugiej strony, pomimo ograniczeń politycznych, niektórzy nauczyciele byli w stanie bronić swoich przekonań i pozycji, stosując typowe strategie w systemie PRL-u: zatajanie niektórych informacji, mowę ciała i protest przeciwko indoktrynacji.

description: Neste artigo analisa-se o efeito das ações regulamentares vento
e neve, com forte variabilidade espacial de intensidade e sentido, no comportamento de uma casca fina triangular em betão, com três apoios, cuja forma foi determinada e otimizada com base na análise não linear de uma membrana sujeita ao seu peso próprio. Para a avaliação dos efeitos do vento e da neve no comportamento estrutural da casca, recorreu-se a uma análise elástica linear com o software ABAQUS. Os resultados obtidos demonstraram que a ação do vento, mas sobretudo o efeito acidental da neve num cenário de cargas deslocadas, produzem esforços significativos de flexão na casca, a sua descompressão e o desenvolvimento de tensões de tração elevadas. A produção destas cascas com recurso à pré-fabricação de módulos, e sem utilização de armaduras ordinárias, requer a utilização de um betão de ultraelevado desempenho reforçado com fibras e a utilização de pré-esforço.
description: In this article the effect of normative loads such as wind and snow, which exhibit strong spatial variability in intensity and direction, on the behavior of a thin triangular concrete shell with three supports is analyzed. The shape of the shell was generated and optimized based on a nonlinear analysis of a membrane subjected to its self-weight. To assess the wind and snow effects, a linear-elastic structural analysis of the shell was performed on the ABAQUS software. The results obtained show that the wind action, but especially the effect of the accidental snowfall, in a scenario of displaced loads, produce important bending moments in the shell, capable of causing its decompression and the development of high tensile stresses. The production of these shells using prefabrication of modules, and without the use of ordinary reinforcement, requires the use of an ultra-high performance fiber-reinforced concrete and the use of prestress.
