description: Evolutionary models form a vital part of stellar population research to understand their evolution, but despite their long history of development, they often misrepresent and misinterpret the properties of stellar population observed through broadband and spectroscopic measurements. With the growing numbers of these synthesis models, model comparison becomes an important analysis to choose a suitable model for upgrade. Along with the model comparison, we reinvestigate the technique of modified Strömgren photometry to measure reliable parameter-sensitive colours and estimate precise model ages and metallicities. The assessment of Rakos/Schulz models with GALEV and Worthey's Lick/IDS model find smaller colour variation: Δ(uz-vz) $\leq$ 0.056, Δ(bz-yz) $\leq$ -0.05 and Δ(vz-yz) $\leq$ 0.061. The study conveys a good agreement of GALEV models with the modified Strömgren colours but with poor UV model predictions with the observed globular cluster data, while the spectroscopic models perform badly due to the use of older isochrone and stellar spectral libraries with inaccurate/insufficient knowledge of various stellar phases and their treatment. Overall, the assessment finds modified Strömgren photometry well suited to study different types stellar populations by mitigating the effects of the age-metallicity degeneracy.

description: We present next-to-leading order predictions for the production of triphoton final states at the LHC and the Tevatron. Our results include the effect of photon fragmentation for the first time and we are able to quantify the impact of different isolation prescriptions. We find that calculations accounting for fragmentation effects at leading order, and those employing a smooth cone isolation where no fragmentation contribution is required, are in reasonable agreement with one another. However, larger differences in the predicted rates arise when higher order corrections to the fragmentation functions are included. In addition we present full analytic results for the $γγγ$ and $γγ+$jet one-loop amplitudes. These amplitudes, which are particularly compact, may be useful to future higher-order calculations. Our results are available in the Monte Carlo code MCFM.

description: Mon travail consiste en une proposition de modèle permettant de transposer di-dactiquement le texte de l’Ethique de Spinoza, soit son principal ouvrage. Auteur majeur de l’époque moderne, dont le nom est inscrit dans le plan d’étude de maturité du gymnase vaudois pour la philosophie, cet auteur demeure passablement difficile à aborder, en raison principalement d’un texte à la réputation difficile tant sa forme est peu habituelle. Celle-ci est composée « more geometrico » comme on le dit, c’est-à-dire à grand renfort de propositions, démonstrations et scolies, soit en repre-nant la forme des traités géométriques qu’on fait habituellement remonter à celui d’Euclide. Je pars de l’hypothèse qu’un texte philosophique ne peut être bien compris et enseigné si on isole la forme du fond. Ainsi, je m’efforce de montrer un certain nombre de thèses spinozistes qu’il est difficile de bien comprendre si on les isole de leur contexte démonstratif. Ensuite de quoi, j’essaie d’amener un mode de sché-matisation du coeur conceptuel de la troisième partie de l’Ethique, dans laquelle Spinoza traite des affects humains. Ces propositions de schématisation devraient permettre à l’enseignant de mieux saisir cette pensée afin de pouvoir l’expliquer plus aisément. Mais peut-être également de s’en inspirer afin de communiquer une pensée qui demeure plutôt difficile d’accès, surtout pour des élèves du gymnase. Enfin, ce travail est l’occasion d’esquisser, dans le prolongement de cette pro-position de schématisation, quelques questions autour des ressources informatiques qui servent de plus en plus de support de communication, et dont il n’est pas certain que la forme n’impose pas parfois des contraintes à notre façon de saisir une pensée complexe. À ce niveau encore, on voit que la forme ne saurait être tout à fait pensée comme indifférente au fond.

description: We theoretically investigate the threshold current for thermally activated switching of a perpendicular magnet by spin-orbit spin torque. Based on the Fokker-Planck equation, we obtain an analytic expression of the switching current, in agreement with numerical result. We find that thermal energy barrier exhibits a quasi-linear dependence on the current, resulting in an almost linear dependence of switching current on the log-scaled current pulse-width even below 10 ns. This is in stark contrast to standard spin torque switching, where thermal energy barrier has a quadratic dependence on the current and the switching current rapidly increases at short pulses. Our results will serve as a guideline to design and interpret switching experiments based on spin-orbit spin torque

Cross-lingual Dependency Transfer with Harmonized Indian Language Treebanks

Publisher: name: University of Tübingen
Year: 2014

description: One of the most important aspect of cross-lingual dependency trans- fer is how different annotation styles which often negatively influence the transfer accuracy are handled. The emerging trend is that the an- notation style of different language treebanks can be harmonized into one style and the cumbersome manual transformation rules thus can be avoided. In this paper, we use harmonized treebanks (POS tagsets and dependency structures of original treebanks mapped to a common style) for inducing dependencies in a cross-lingual setting. We transfer dependencies using delexicalized parsers that use harmonized version of the original treebanks. We apply this approach to five Indian lan- guages (Hindi, Urdu, Telugu, Bengali and Tamil) and show that best performance can be obtained in delexicalized parsing when the transfer takes place from Indian language (IL) to IL treebanks.

description: We introduce a framework for model reduction of chain models for dissipative particle dynamics (DPD) simulations, where the characteristic size of the chain, pressure, density, and temperature are preserved. The proposed methodology reduces the number of degrees of freedom required to represent a particular system with complex molecules (e.g., linear polymers). Based on geometrical considerations we map fine-grained models to a reference state through a consistent scaling of the system, where short length and fast time scales are disregarded while the properties governing the phase equilibria are preserved. Following this coarse graining process we consistently represent high molecular weight DPD chains (i.e., >200 beads per chain) with a significant reduction in the number of particles required (i.e., > 20 times the original system).

description: Software-as-a-Service (SaaS) is a viable option for some companies bearing their business processes. There is a considerable adoption rate, with companies already using more than two services for over two years. However, while some companies have plans to put more business processes supported by these services in the near future, others do not know if they will. They have several concerns regarding the software providers service level. These concerns are mainly technical and functional issues, service availability and payment models. There are major changes compared to the traditional software that have implications on how the software is developed and made available to the users. The existing research addresses specific aspects and few studies give a broader view of the implications of SaaS for anyone who develops and provides software, and also for those who consumes it as an end user. What are the real needs of the Portuguese market? What fears and what is being done to mitigate them? Where should we focus our attention related to the SaaS offering in order to create more value? Thus, to analyze these questions four exploratory case studiesare used to assess the possible implications of SaaS on software developers or software providers based in Portugal and also on end-users. This article appears in the context of a realistic and deep research that includes the involvement of managers, leaders and decision makers of Portuguese companies, to realize what actually constitutes a problem in SaaS and what effectively companies would like to have available in this offer. The results of this study reveal that SaaS effectively constitutes a very interesting and solid solution for the development of Portuguese companies, however there is a lack for greater efforts particularly in terms of customization for each customer (tenant) and integration with the back-end on-premise applications.
Growth Factor Pathways in Development of Endocrine Resistance in Human Breast Cancer Cells

Subjects: C130 - Cell biology

description: Growth of MCF7 McGrath human breast cancer cells (MCF7) under conditions of longterm oestrogen deprivation results in loss of oestrogen dependence for growth (MCF7?ED) and provides a model system to study the molecular basis of endocrine resistance in breast cancer. MCF7?ED cells had higher levels of phosphorylated mitogen activated protein kinase (MAPK) than MCF7 cells. However, since a similar increase inphosphorylated MAPK was found in MCF7 cells within hours of insulin withdrawal from the medium, and as the growth rate of the MCF7?ED cells in the absence of oestrogen was only marginally affected by the MAPK inhibitors PD98059 (2.5?20?g/ml) and U0126 (2.5?10?M), it would seem that raised levels of phosphorylated MAPK are a response to insulin withdrawal rather than a mechanism for enhanced basal growth.By contrast, although no difference in levels of phosphorylated?Akt (Thr308/Ser473) were observed between MCF7 and MCF7?ED cells, the growth rate of the MCF7?ED cells in the absence of oestrogen was inhibited by the inhibitor of phosphatidylinositol 3?kinase (PI3K), LY294002 (2.5?10?M). The IGF1R inhibitor Picropodophyllin (PPP) also inhibited growth of the MCF7?ED cells and decreased phosphorylation of Akt and p?70S6K, a major downstream target of mTORC1. The mTORC1 inhibitor rapamycin could decrease the growth of stock MCF7?ED cells but not MCF7 cells suggesting a mechanistic role of PI3K/Akt/mTORC1 in oestrogen independence. Combination of rapamycin (1nM) with LY294002 (2.5?10?M) revealed greater growth inhibition of MCF7?ED cells than when added alone which may be explained by blocking thenegative feedback loop that exists between mTORC1/p?70S6K and PI3K. Comparison with other cell models showed that long?term oestrogen deprived T47D cells exhibited even greater sensitivity towards rapamycin alone or in combination with LY294002. In ZR?75?1 cells, however, rapamycin alone or in combination with LY294002 could inhibit growth of the oestrogen maintained as well as the oestrogen deprived cells. The above findings thus reinstate the emerging potential of combination therapy with mTOR and PI3K inhibitors in breast cancer.

description: We use a tight-binding model and the random-phase approximation to study the Coulomb excitations in simple-hexagonal-stacking multilayer graphene and discuss the field effects. The calculation results include the energy bands, the response functions, and the plasmon dispersions. A perpendicular electric field is predicted to induce significant charge transfer and thus capable of manipulating the energy, intensity, and the number of plasmon modes. This could be further validated by inelastic light scattering or electron-energy-loss spectroscopy.

description: This study investigates how digital archival collections influence the professional practice of academic historians and library professionals by uniquely analysing beliefs, attitudes, and awareness among staff at Newcastle University.Existing research provides fearful conclusions on historians’ use of digital collections, almost universally arguing that packages created by commercial organizations have negatively affected academic research. This study reviewed the high-profile works of Tim Hitchcock, Michelle Moravec, Elizabeth Toon, and Andrew Bingham who have been particularly influential in asserting this belief.However, this research found little tangible evidence to support the received wisdom from existing studies. Furthermore, library professionals have so far been absent from the discussion, which limits full comprehension of how academic faculty engage with their institution’s digital archival collections.This study held interviews with a sample of historians and library professionals at Newcastle University and performed content analysis of transcripts, using NVivo where appropriate. The findings show that historians and library professionals’ expressed beliefs and attitudes demonstrate abundant awareness of issues relating to “digital selectivity”. They account for this in their practice. This finding contradicts existing studies.The project also finds that a lack of standardized practice has produced inadequate data for all research into this issue. It concludes that further research into historians’ information-seeking behaviour is necessary, but that standardized metadata practice must be enacted first.As the project provides the first examination of perceptions, attitudes, and beliefs of both academic historians and library staff, it provides new insight and makes an original contribution to existing research on the subject.

description: We have investigated the transport and magnetic properties of group-IV ferromagnetic semiconductor Ge1-xFex films (x = 1.0 and 2.3 %) with and without boron doping grown by molecular beam epitaxy (MBE). In order to accurately measure the transport properties of 100-nm-thick Ge1-xFex films, (001)-oriented silicon-on-insulator (SOI) wafers with an ultra-thin Si body layer (~5 nm) were used as substrates. Owing to the low Fe content, the hole concentration and mobility in the Ge1-xFex films were exactly estimated by Hall measurements because the anomalous Hall effect in these films was found to be negligibly small. By boron doping, we increased the hole concentration in Ge1-xFex from ~1018 cm-3 to ~1020 cm-3 (x = 1.0%) and to ~1019 cm-3 (x = 2.3%), but no correlation was observed between the hole concentration and magnetic properties. This result presents a contrast to the hole-induced ferromagnetism in III-V ferromagnetic semiconductors.

More precisely, we show that if the second largest eigenvalue of a $d$-regular graph $G$ is less than $d-\frac{2k-1}{d+1}$, then $G$ contains at least $k$ edge-disjoint spanning trees, when $k\in \{2,3\}$. We construct examples of graphs that show our bounds are essentially best possible. We conjecture that the above statement is true for any $k

description: We consider the thermodynamic properties of systems in contact with an information source and focus on the consequences of energetic cost associated with the exchange of information. To this end we introduce the model of a thermal tape and derive a general bound for the efficiency of work extraction for systems in contact with such a tape. Depending on the perspective, the correlations between system and tape may either increase or reduce the efficiency of the device. We illustrate our general results with two exactly solvable models, one being an autonomous system, the other one involving measurement and feedback. We also define an ideal tape limit in which our findings reduce to known results.

description: L’informatique est en passe de devenir une discipline obligatoire au gymnase. Beaucoup de besoins nouveaux vont naître de ce changement parmi lesquels il y aura la nécessité d’avoir des manuels scolaires à disposition. Le plus simple dans ce cas (le moins coûteux en ressources) est de partir d’un manuel existant et de l’adapter aux besoins du public cible qui nous intéresse. Dans le cadre de ce travail, il a été décidé de partir de l’ouvrage d’André Schiper qui se nomme : « Découvrir le numérique : une introduction à l’informatique et aux systèmes de communication ». Le problème est que cet ouvrage a été conçu pour les élèves de 1ère année de l’EPFL qui ont un niveau plus élevé que les élèves de 1ère année du gymnase. La question est de savoir comment adapter un ouvrage dont les explications risquent fortement de dépasser la capacité de compréhension des élèves pour lequel il est destiné ? Quels sont les éléments à maintenir, quels sont ceux dont une reformulation est indispensable ? Quels sont ceux à supprimer, quels sont ceux à ajouter ? C’est en travaillant sur le 1e chapitre de cet ouvrage, que nous avons tenté de répondre à ces différentes questions. Nous avons aussi profité de modifier ce chapitre pour qu’il soit désormais adapté aux élèves du gymnase.

description: We discuss the action principle and resulting Hamiltonian equations of motion for a class of integer-valued cellular automata introduced recently [1]. Employing sampling theory, these deterministic finite-difference equations are mapped reversibly on continuum equations describing a set of bandwidth limited harmonic oscillators. They represent the Schroedinger equation. However, modifications reflecting the bandwidth limit are incorporated, i.e., the presence of a time (or length) scale. When this discreteness scale is taken to zero, the usual results are obtained. Thus, the linearity of quantum mechanics can be traced to the postulated action principle of such cellular automata and its conservation laws to discrete ones. The cellular automaton conservation laws are in one-to-one correspondence with those of the related quantum mechanical model, while admissible symmetries are not.

description: It is thought that the proposed new family of multi-functional materials namely the ferroelectric thermoelectrics may exhibit enhanced functionalities due to the coupling of the thermoelectric parameters with ferroelectric polarization in solids. Therefore, the ferroelectric thermoelectrics are expected to be of immense technological and fundamental significance. As a first step towards this direction, it is most important to identify the existing high performance thermoelectric materials exhibiting ferroelectricity. Herein, through the direct measurement of local polarization switching we show that the recently discovered thermoelectric semiconductor $AgSbSe_{2}$ has local ferroelectric ordering. Using piezo-response force microscopy, we demonstrate the existence of nanometer scale ferroelectric domains that can be switched by external electric field. These observations are intriguing as $AgSbSe_{2}$ crystalizes in cubic rock salt structure with centro-symmetric space group (Fm-3m) and therefore no ferroelectricity is expected. However, from high resolution transmission electron microscopy (HRTEM) measurement we found the evidence of local superstructure formation which, we believe, leads to local distortion of the centro-symmetric arrangement in $AgSbSe_{2}$ and gives rise to the observed ferroelectricity. Stereochemically active $5s^{2}$ lone pair of Sb can also give rise to local structural distortion, which creates ferroelectricity in $AgSbSe_{2}$.
At the roots of limbed vertebrate diversity: new light on patterns and processes of early tetrapod evolution
Creators: name: Author, Unknown
Publisher: name: University of Lincoln
Year: 2023

description: The origin of limbed vertebrates (tetrapods) from their fish-like ancestors is an iconicexample of a major evolutionary radiation. The group of vertebrates that covered thistransition, the early tetrapods, encompassed 12-15 groups, ranging from the Late Devonian tothe Middle Cretaceous. The tempo and mode of the evolutionary diversification undergone bythese organisms, however, remains largely unknown. To fill this gap in our understanding ofthe early proliferation of vertebrates, the core objective of the project is to quantify models ofskeletal transformation across the transition from fish-like ancestors to early tetrapods in lightof a revised, amended, and expanded database of cranial traits. Studies so far have relied on alimited database of osteological characters, often with few characters for certain complexes ora reduced taxon set for tetrapods over the transition. Here, I create a new database that will beused to retrieve a tree for the group which will be subjected to macroevolutionary analyses,answering questions concerned with rate and disparity. The retrieved tree shows a wellresolved pattern of taxa with groupings that have been found previously. New taxa haveimpacted the tree tremendously pushing the divergence between the stem-amniotes and stemamphibians backwards. The analysis of disparity reveals that phylogenetic diversificationresulted in higher degrees of morphological disparity among clades relative to the degrees ofwithin clade variation. Both the rate and disparity analyses indicate that early tetrapods showa burst of evolution at the start of the lineage and also at the amphibian-amniote split. Thisstudy has shed light upon how the early tetrapod group has evolved, revealing that theseorganisms underwent a degree of rapid diversification at the beginning of the clade acrossboth analyses as well as creating a new tree for the group. The next step would be to add postcranial characters to the dataset allowing an even more comprehensive look at the earlytetrapod radiation. Overall, my research contributes to appreciate the patterns and ratesunderlying the early proliferation of tetrapods, which is a fundamental step to advance ourunderstanding of the subsequent diversification of modern tetrapods and their morphologicalcomplexities.

description: This is one of a collection of 11 fact sheets bringing together existing scientific information on the impacts of sediment on freshwater and estuarine fish used for mahinga kai. These fact sheets bring together existing scientific information on these effects, along with expert scientific knowledge, in an easy-to-read format by community groups and land-water managers interested in protecting mahinga kai. The sensitivity of each of 11 species of fish are summarised on a dial from low to high. The assessment is made by considering the influence of sediment on habitat, behaviour, feeding, growth and survival, all in the context of background information such as the life cycle and places where the species are usually found. Scientific references are provided for further detail. Readers might also be interested in the Taonga Species Fact Sheets which provide a broader range of information on selected species.

description: We report the discovery of four doubly imaged quasar lenses. All the four systems are selected as lensed quasar candidates from the Sloan Digital Sky Survey data. We confirm their lensing hypothesis with additional imaging and spectroscopic follow-up observations. The discovered lenses are SDSS J0743+2457 with the source redshift z_s=2.165, the lens redshift z_l=0.381, and the image separation theta=1.034", SDSS J1128+2402 with z_s=1.608 and theta=0.844", SDSS J1405+0959 with z_s=1.810, z_l~0.66, and theta=1.978", and SDSS J1515+1511 with z_s=2.054, z_l=0.742, and theta=1.989". It is difficult to estimate the lens redshift of SDSS J1128+2402 from the current data. Two of the four systems (SDSS J1405+0959 and SDSS J1515+1511) are included in our final statistical lens sample to derive constraints on dark energy and the evolution of massive galaxies.

description: Predator-prey relationships are one of the most studied interactions in population ecology. However, little attention has been paid to the possibility of role exchange between species once determined as predators and preys, despite firm field evidence of such phenomena in the nature. In this paper, we build a model capable of reproducing the main phenomenological features of one reported predator-prey role-reversal system, and present results for both the homogeneous and the space explicit cases. We find that, depending on the choice of parameters, our role-reversal dynamical system exhibits excitable-like behaviour, generating waves of species' concentrations that propagate through space.

Investigating the morphology and functional properties of Sylviidae nests

description: Investigating the functional properties of bird nests has received an increasedinterest in recent years. Despite this, quantitative data for nest composition is scarcefor many species and relatively little is known about functional aspects of nestconstruction across species. This thesis provides additional quantitative data fornest composition and investigates the thermal and hydrological properties of nestsfrom three closely related species from the Sylviidae family; Eurasian BlackcapsSylvia atricapilla, Eurasian Reed Warblers Acrocephalus scirpaceus and WillowWarblers Phylloscopus trochilus. Willow Warblers built nests with the greatest masswhereas Blackcap nests were the smallest in mass of the three species. Principalcomponent analysis revealed that there was interspecific variation in thecomposition of warbler nests. Willow Warbler nests were characterised by a largerquantity of moss and feathers than in Reed Warbler and Blackcap nests, with anabsence of invertebrate silk and artificial materials. Reed Warbler nests wereprimarily composed of dry grasses, invertebrate silk and artificial materials.Blackcap nests were constructed with roots and grasses, artificial materials andinvertebrate silk. Internal cooling rates were greatest for Blackcap nests under stilland moving air conditions in comparison to Reed Warbler and Willow Warbler nests.Internal cooling rates in moving air were the smallest for Reed Warbler nests.Heavier nests with thicker nest floors were better insulating than smaller nests understill air conditions. Warbler nests were able to reduce the effect of air movement ontemperature loggers despite the increasing internal cooling rate, suggesting thatpresence of a nest is beneficial during periods of air movement. Nests with greatergrass mass were better at reducing the effect of air movement on the internalmicroclimate of warbler nests. The effect of test location on the output for thermaldata by temperature loggers placed in warbler nests was also investigated bycomparing the thermal measures recorded in an open laboratory and an enclosedtest chamber. Test location had a significant effect on thermal measurementsrecorded for nests. Species had a significant effect on the hydrological properties ofwarbler nests. Willow Warbler nests had the longest drying times and greater waterabsorption of the three species. Nest materials did not influence the hydrologicalproperties of warbler nests. This thesis provides further quantified data for the iicomposition of nest materials and builds on the evidence for the relationshipbetween avian nest construction and function.

description: Implicit solvers present strong limitations when used on supercomputing facilities and in particular for adaptive mesh-refinement codes. We present a new method for implicit adaptive time-stepping on adaptive mesh refinement-grids. We implement it in the radiation hydrodynamics solver we designed for the RAMSES code for astrophysical purposes and, more particularly, for protostellar collapse. We briefly recall the radiation hydrodynamics equations and the adaptive time-stepping methodology used for hydrodynamical solvers. We then introduce the different types of boundary conditions (Dirichlet, Neumann, and Robin) that are used at the interface between levels and present our implementation of the new method in the RAMSES code. The method is tested against classical diffusion and radiation hydrodynamics tests, after which we present an application for protostellar collapse. We show that using Dirichlet boundary conditions at level interfaces is a good compromise between robustness and accuracy and that it can be used in structure formation calculations. The gain in computational time over our former unique time step method ranges from factors of 5 to 50 depending on the level of adaptive time-stepping and on the problem. We successfully compare the old and new methods for protostellar collapse calculations that involve highly nonlinear physics. We have developed a simple but robust method for adaptive time-stepping of implicit scheme on adaptive mesh-refinement grids. It can be applied to a wide variety of physical problems that involve diffusion processes.

description: We consider a class of nonlocal reaction-diffusion problems, referred to as replicator-mutator equations in evolutionary genetics. By using explicit changes of unknown function, we show that they are equivalent to the heat equation and, therefore, compute their solution explicitly. Based on this, we then prove that, in the case of beneficial mutations in asexual populations, solutions dramatically depend on the tails of the initial data: they can be global, become extinct in finite time or, even, be defined for no positive time. In the former case, we prove that solutions are accelerating, and in many cases converge for large time to some universal Gaussian profile. This sheds light on the biological relevance of such models.

description: We prove that if $H$ denotes the operator corresponding to the canonical Dirichlet form on a possibly locally infinite weighted graph $(X,b,m)$, and if $v:X\to \mathbb{R}$ is such that $H+v/\hbar$ is well-defined as a form sum for all $\hbar >0$, then the quantum partition function $\mathrm{tr}(\mathrm{e}^{-β\hbar ( H + v/\hbar)})$ satisfies $$ \mathrm{tr}(\mathrm{e}^{-β\hbar ( H + v/\hbar)})\xrightarrow[]{\hbar\to 0+}\sum_{x\in X} \mathrm{e}^{-βv(x)} \text{ for all $β>0$}, $$ regardless of the fact whether $\mathrm{e}^{-βv}$ is apriori summable or not. We also prove natural generalizations of this semiclassical limit to a large class of covariant Schrödinger operators that act on sections in Hermitian vector bundle over $(X,m,b)$, a result that particularly applies to magnetic Schrödinger operators that are defined on $(X,m,b)$.
