description: Density waves are inherent to the phase diagrams of materials that exhibit unusual, and sometimes extraordinarily useful properties, such as superconductivity and colossal magnetoresistance. While the pure charge density waves (CDW) are well described by an itinerant approach, where electrons are treated as waves propagating through the crystal, the charge-orbital ordering (COO) is usually explained by a local approach, where the electrons are treated as localized on the atomic sites. Here we show that in the half-doped manganite La0.5Sr1.5MnO4 (LSMO) the electronic susceptibility, calculated from the angle-resolved photoemission spectra (ARPES), exhibits a prominent nesting-driven peak at one quarter of the Brillouin zone diagonal, that is equal to the reciprocal lattice vector of the charge-orbital pattern. Our results demonstrate that the Fermi surface geometry determines the propensity of the system to form a COO state which, in turn, implies the applicability of the itinerant approach also to the COO.

A powerful tool for measuring Higgs boson associated Lepton Flavour Violation

Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In models with extended Higgs sectors, Higgs-boson-mediated Lepton Flavour Violation (LFV) can naturally appear. We study the physics potential of an electron-photon collider %as an option of the International Linear Collider on searching LFV processes $e^-γ\to\ell^-φ(\ell=μ,τ; φ=H, A)$ where $H$ and $A$ are extra CP even and odd Higgs bosons, respectively, in the minimal supersymmetric standard model and the effective two Higgs doublet model. The production cross section can be significantly large for the maximal allowed values of the LFV coupling constants under the current experimental data. Present experimental upper bounds on the effective LFV coupling constants would be considerably improved by searching these processes, which would be better than MEG and COMET experiments and also those at LHCb and SuperKEKB. Moreover, one can separately measure chirality of effective LFV coupling constants via these processes by selecting electron polarizations.

description: Ionizing radiation is known to delay the cell cycle progression. In particular after particle exposure significant delays have been observed and it has been shown that the extent of delay affects the expression of damage such as chromosome aberrations. Thus, to predict how cells respond to ionizing radiation and to derive reliable estimates of radiation risks, information about radiation-induced cell cycle perturbations is required. In the present study we describe and apply a method for retrieval of information about the time-course of all cell cycle phases from experimental data on the mitotic index only. We study the progression of mammalian cells through the cell cycle after exposure. The analysis reveals a prolonged block of damaged cells in the G2 phase. Furthermore, by performing an error analysis on simulated data valuable information for the design of experimental studies has been obtained. The analysis showed that the number of cells analyzed in an experimental sample should be at least 100 to obtain a relative error less than 20%.

description: We complete our high-accuracy studies of the lattice ghost propagator in Landau gauge in Numerical Stochastic Perturbation Theory up to three loops. We present a systematic strategy which allows to extract with sufficient precision the non-logarithmic parts of logarithmically divergent quantities as a function of the propagator momentum squared in the infinite-volume and $a\to 0$ limits. We find accurate coincidence with the one-loop result for the ghost self-energy known from standard Lattice Perturbation Theory and improve our previous estimate for the two-loop constant contribution to the ghost self-energy in Landau gauge. Our results for the perturbative ghost propagator are compared with Monte Carlo measurements of the ghost propagator performed by the Berlin Humboldt university group which has used the exponential relation between potentials and gauge links.

description: Development of the systems of visual prostheses by human Intervention to restore functional
 vision. Blindness suffering has recently undergone a renaissance that has been fueled by a group
 or combination of celebrity and government interest and progress in the field of bioengineering
 which led to the discovery of a neuroprosthetic system.
 Blindness is generally considered one of the most serious handicaps of human beings. Due
 to the complexity of the visual system and despite numerous research efforts, rehabilitation
 developments in this field seem to be slow. However, this pessimistic picture might be changed
 soon since technological advances offer a whole new range of possibilities.
 Several projects aimed towards developing visual prostheses have been launched recently. Such
 devices would restore lost function bypassing the damaged structures and electrically
 stimulating the remaining visual pathway. Obviously, damage to other structures should be
 avoided and the „artificial vision" provided by the prosthesis has to be useful to the patient. A
 number of important factors (electrical, surgical, biocompatibility, psychophysical) have thus to
 be thoroughly investigated and considered.
 This work intends to set the necessary background to understand visual perception in the context
 of artificial vision and the importance of the determination of minimum requirements for a visual
 prosthesis to restore useful vision. First, the basic anatomy and physiology of the visual system
 will be outlined and the basic issues of blindness and low vision will be discussed. Further along,
 the concept of visual prostheses will be explained in more detail. The different design
 approaches will be described, summarizing the current status of the research.

Subjects: Webinar

description: In this talk I will give an overview of the databases and tools built within my group to exploit the sequence and structure data available for antibodies to build a better understanding of the immune system and aid in the development of biotherapeutics. Our focus is to move from a sequence based view of the system that is common in the area of immunoinformatics to a structure based one. To this end we have built the structural antibody database (SAbDab) and the computational antibody prediction toolset SAbPred for modelling and designing antibodies. These tools are then used to enrich the available sequence data in our Observed Antibody Space (OAS) a database of nearly two billion antibody sequences, Thera-SAbDab, a collection of all antibody and nanobody-related therapeutics recognized by the World Health Organisation and most recently CoV-AbDab, an annotated database of all known antibody and nanobody binders to betacoronoviruses. I will describe how bringing together the huge availability of sequence data alongside structural data and prediction tools has allowed us to develop insights into the natural immune repertoire, response of the repertoire to vaccines and the development of antibody therapeutics.

description: We discuss the angular resolution obtained for events registered with the surface detector alone and for hybrid events, i.e., those observed simultaneously by both the surface and fluorescence detectors. The angular accuracy of the surface detector is directly extracted from the data itself and on an event by event basis, and is given as a function of the number of stations triggered by the event and of the zenith angle of the shower. We compare the angular resolution of the surface detector obtained from hybrid events with the one obtained from the surface detector alone.

description: Outdoor built environments can be designed to enhance thermal comfort, yet the relationship between the two is often assessed in whole-body terms, overlooking the asymmetric nature of thermal interactions between the human body and its surroundings. Moreover, the radiative component of heat exchange-dominant in hot and dry climates-is typically lumped into a single artificial metric, the mean radiant temperature, rather than being resolved into its shortwave and longwave spectral components. The shortwave irradiation distribution on the human body is often highly anisotropic, causing localized thermal discomfort in outdoor environments. However, no existing methods effectively quantify shortwave and longwave irradiation distributions on the human body. To address this gap, we developed two methods to quantify these processes. The first approach uses an outdoor thermal manikin with a white-coated side, enabling the separation of spectral components by subtracting measurements from symmetrically corresponding surface zones of tan color. The second hybrid approach converts radiometer measurements in six directions into boundary conditions for computational thermal manikin simulations. We evaluated irradiation distributions for various body parts using both methods during outdoor measurements across sunny, partially shaded, and fully shaded sites under warm to extremely hot conditions. In most cases, the two methods produced closely aligned results, with divergences highlighting their respective strengths and limitations. Additionally, we used the manikin to quantify irradiation attenuation provided by five long-sleeve shirts with colors ranging from white to black. These advanced methods can be integrated with airflow and thermoregulatory modeling to optimize outdoor built environments for enhanced human thermal comfort.

description: A phenomenological quasiparticle model, featuring dynamically generated self-energies of excitation modes, successfully describes lattice QCD results relevant for the QCD equation of state and related quantities both at zero and non-zero net baryon density. Here, this model is extended to study bulk and shear viscosities of the gluon-plasma within an effective kinetic theory approach. In this way, the compatibility of the employed quasiparticle ansatz with the apparent low viscosities of the strongly coupled deconfined gluonic medium is shown.

Urban characteristics as the determinants of air passenger generation
Creators: name: Ghosh, Ranen Kumar
Publisher: name: University of British Columbia
Year: 2011

description: Both the process of designing better plans and the process of evaluating plans depend heavily on a detailed understanding of the interrelationships among urban activities. This thesis explores the relationship between some of the characteristics of urban areas and their air passenger generation. The research methodology consists of a review of the literature on air passenger generation. Secondly, data from thirty-nine Canadian cities are used for empirical analysis. Factor analysis, grouping analysis and multiple regression techniques are employed. The results explain that, in general, the factor of urbanization plays an important role in determining air passenger generation from urban areas. Also, for some cities, the trade and service functions discourage air passenger generation to some extent. Moreover, this study suggests that available techniques of analysis can be used successfully, to improve upon those which are commonly used in developing predictive equations for air passenger generation. It is evident from the models developed in this study that, for a group of cities, the more they are similar in their characteristics, the better is the predictive equation. Finally, the implications and limitations of this study have been discussed along with the suggestions for further research.

description: In EC3, the fatigue life of a steel structure subjected to a cyclic load is estimated by its detail category. This category is based on the S-N, curves which are obtained by applying the Basquin model. Statistically, this model does not allow extrapolating the S-N curves in the HCF region, neither does it consider the runouts. This affects the fatigue life estimation when a structure bears loading in HCF. To overcome these deficiencies, a new method based on a Weibull distribution is applied.

description: Pulse profile modelling using X-ray data from NICER permits the inference of mass and radius for rotation-powered millisecond pulsars. This in turn constrains the equation of state of cold dense matter. Previous studies indicate that the uncertainty in the inferred radius should reduce as neutron star spin rate increases. Here we test this using one of the pipelines currently being used for pulse profile modelling with NICER data. We synthesize a set of pulse profiles, assuming different neutron star spin frequencies, spanning the range (25-700) Hz. All of the simulated data sets are generated with the same (single) hot spot configuration, assuming a neutron star mass and radius of $1.6\,M_{\mathrm{\odot}}$ and $10$ km. For this restricted set of synthetic data, we find no improvement in the radius credible interval once spin frequency exceeds a certain value (in this specific case $\sim 200$ Hz). If this result were to apply more generally, it would have important implications for the observing strategy for current and future pulse profile modelling missions: targets can be prioritized based on properties other than their spin frequencies, as long as we are in the millisecond range.

Subjects: subject: 510 Mathematics

description: Let G be a group acting properly on a simply connected manifold. There is a fundamental domain DG for that action. The map, which assigns to each subgroup of finite index its fundamental domain D yields a correspondence between coverings of DG of finite degree and finite index subgroups of G. We are interested in the question how the branching points behave under the transition from DG to its finite covers. This work presents an approach which allows to solve such questions in a purely group theoretical framework. This approach is applied to a concrete example.

description: Six urease-negative Campylobacter strains were isolated from cattle feces over a 19-month period from 2009 to 2010. These strains were initially identified as Campylobacter sputorum by 16S rRNA gene and atpA typing. Initial studies characterizing these strains by multi-locus sequence typing and genome sequencing further supported their classification as C. sputorum but indicated that these strains form a divergent clade within the species. A polyphasic study was undertaken here to clarify their taxonomic position. Phylogenetic analyses were performed based on 16S rRNA gene sequences and the concatenated sequences of 330 core genes, with the latter analysis also placing the six strains into a clade distinct from the three C. sputorum biovars. Pairwise digital DNA-DNA hybridization values identified these strains as C. sputorum, and pairwise average nucleotide identity values were consistent with those observed between current Campylobacter subspecies pairs. Standard phenotypic testing was also performed. All strains are microaerobic, anaerobic, motile, Gram-negative, and oxidase and catalase positive; cells are curved rods or spiral. Strains can be distinguished from the C. sputorum biovars by the presence of alkaline phosphate activity and TTC reduction and absence of nitrate reduction. The data presented here show that these strains represent a novel subspecies within Campylobacter sputorum, for which the name Campylobacter sputorum subsp. bovis subsp. nov. (type strain RM8705T=LMG 32300T=CCUG 75470T) is proposed.

description: High-dimensional entanglement in qudit states offers a promising pathway towards the realization of practical, large-scale quantum systems that are highly controllable. These systems can be leveraged for various applications, including advanced quantum information processing, secure communications, computation, and metrology. In this context, quantum frequency combs have a crucial role as they inherently support multiple modes in both temporal and frequency domains, while preserving a single spatial mode. The multiple temporal and frequency modes of quantum frequency combs facilitate the generation, characterization, and control of high-dimensional time-frequency entanglement in extensive quantum systems. In this review article, we provide an overview of recent technological advancements in high-dimensional energy-time entangled quantum frequency combs. We explore how these time-frequency qudits, achieved using scalable telecommunications-wavelength components, can empower the creation of large-scale quantum states. Advances in quantum frequency combs can unlock new capabilities and versatility for promising developments in quantum science and technology.

description: We review the first decade of extensive optical studies of ferromagnetic, III-Mn-V diluted magnetic semiconductors. Mn introduces holes and local moments to the III-V host, which can result in carrier mediated ferromagnetism in these disordered semiconductors. Spectroscopic experiments provide direct access to the strength and nature of the exchange between holes and local moments; the degree of itineracy of the carriers; and the evolution of the states at the Fermi energy with doping. Taken together, diversity of optical methods reveal that Mn is an unconventional dopant, in that the metal to insulator transition is governed by the strength of the hybridization between Mn and its p-nictogen neighbor. The interplay between the optical, electronic and magnetic properties of III-Mn-V magnetic semiconductors is of fundamental interest and may enable future spin-optoelectronic devices.

description: This study examines the influence of Madden-Julian Oscillation (MJO) on Indonesian precipitation during the extended boreal summer (May to September). The MJO is one of the dominant intraseasonal variabilities that influence the extreme precipitation in the tropics, especially in Indonesia. The episodes of intense precipitation (95th percentiles) during active MJO phases from 1998-2015 are evaluated using the daily precipitation datasets from the gridded Asian Precipitation Highly Resolved Observational Data Integration Towards Evaluation of Water Resources (APHRODITE) and several station rain gauges. The boreal summer MJO influences the probability of extreme precipitation, especially in the west and north parts of Indonesia. The west part experiences an increase in the probability of extreme precipitation by up to 55\% and 80\% during phases 2 and 3, respectively. Moreover, the extreme precipitation probability in the north part increases by up to 40 to 70\% during phases 2 to 4. On the other hand, the influence of MJO is relatively weak in the south and east parts of Indonesia. The contrast of the precipitation response between the north and south parts of Indonesia is consistent with the northward movement of boreal summer MJO.

description: Este trabalho investiga imagens de pinturas, disponíveis na internet, que retrataram a alquimia em diferentes séculos. Com base nos estudos dos epistemólogos da Ciência, sabemos que existem inúmeras concepções deturpadas sobre como a Ciência funciona. Estas visões equivocadas podem causar má interpretação acerca da construção do conhecimento científico. Estas imagens são muitas vezes encontradas em alguns livros didáticos. Dai a importância de estudá-las, pois sua utilização pode reforçar uma visão incompleta e/ou incorreta da Ciência. Analisamos somente as pinturas e comentários associados. Utilizamos o software WebQDA para o cruzamento das informações atribuídas às pinturas. Esta análise permitiu concluir que as pinturas tem o potencial de induzir concepções deturpadas sobre a Ciência, especialmente concepções individualista e elitista da ciência, rígida, algorítmica; e ainda aproblemática e ahistórica, fechada e dogmática. Este artigo aponta para novas pesquisas que estudam se a utilização destas pinturas em contextos de ensino e aprendizagem realmente confirmam as potencialidades indicadas.

description: This research provides an analysis of extreme events in the solar wind and in the magnetosphere due to disturbances of the solar wind. Extreme value theory has been applied to a 20 year data set from the Advanced Composition Explorer (ACE) spacecraft for the period 1998-2017. The solar proton speed, solar proton temperature, solar proton density and magnetic field have been analyzed to characterize extreme events in the solar wind. The solar wind electric field, vB$_{z}$ has been analyzed to characterize the impact from extreme disturbances in the solar wind to the magnetosphere. These extreme values were estimated for one-in-40 and one-in-80 years events, which represent two and four times the range of the original data set. The estimated values were verified by comparison with measured values of extreme events recorded in previous years. Finally, our research also suggests the presence of an upper boundary in the magnitudes under study.
Towards algorithm-free physical equilibrium model of computing

description: Our computers today, from sophisticated servers to small smartphones, operate based on the same computing model, which requires running a sequence of discrete instructions, specified as an algorithm. This sequential computing paradigm has not yet led to a fast algorithm for an NP-complete problem despite numerous attempts over the past half a century. Unfortunately, even after the introduction of quantum mechanics to the world of computing, we still followed a similar sequential paradigm, which has not yet helped us obtain such an algorithm either. Here a completely different model of computing is proposed to replace the sequential paradigm of algorithms with inherent parallelism of physical processes. Using the proposed model, instead of writing algorithms to solve NP-complete problems, we construct physical systems whose equilibrium states correspond to the desired solutions and let them evolve to search for the solutions. The main requirements of the model are identified and quantum circuits are proposed for its potential implementation.
Do ecossistema à Wiki: estudo comparativo da colaboração de duas turmas do Ensino Secundário no PBworks

description: A Web 2.0 disponibiliza um universo de ferramentas colaborativas muito diversas e as Wikis são uma das mais promissoras em contextos educativos. Neste trabalho apresentam-se os resultados obtidos num estudo efetuado na plataforma PBworks®, utilizada por duas turmas do Ensino Secundário em 2011 e 2012. Após a saída de campo a um ecossistema, os alunos desenvolveram on-line uma Wiki avaliada, com distinto número de páginas e diferente feedback dado pelo professor. A análise comparativa dos históricos das páginas revelou total participação dos alunos e intensidades colaborativas variáveis entre as Wikis construídas. As respostas dadas pelos alunos mais participativos e menos participativos mostrou que os primeiros dão ênfase à ação, enquanto os segundos mostraram desconfiança em relação às interações sociais e à tecnologia utilizada. Sugere-se que em trabalhos futuros, se enriqueçam os instrumentos de pesquisa aplicados nomeadamente a aplicação de um inquérito por entrevista.

Capital humano versus capital tecnológico: projetos tecnológicos na educação: uma leitura da estratégia portuguesa
Creators: name: Morgado, Evandro

Publisher: name: Internet Latent Corpus Journal
Year: 2014

description: Este artigo apresenta um estudo desenvolvido a partir do corpus latente na Internet, tendo em vista uma análise do discurso dos líderes governamentais portugueses, entre 2007 e 2014, relativamente à visão estratégica portuguesa no que se refere às políticas de investimento em projetos de cariz tecnológico na educação. Esta análise procura minudenciar o nível de paridade entre o investimento no capital humano e no capital tecnológico. A tendência para a principal aposta no capital tecnológico contraria fortemente a revisão da literatura que sublinha a importância da capitalização do fator humano, enquanto garante da proficiência da tecnologia em contexto educativo. Os resultados evidenciam uma disparidade entre o investimento no capital humano e o capital tecnológico, sendo que este último é, de uma forma geral, o foco do esforço financeiro.

description: O estudo procura identificar os determinantes de satisfação e insatisfação no uso e adoção de software entre os utilizadores de software dedicado à investigação qualitativa, nomeadamente à análise qualitativa de dados. O ponto de partida é o de considerar o software como um prestador de serviços aos seus utilizadores. Nesta perspectiva, procurou-se recolher a perceção de utilizadores deste tipo de software. Foram analisadas as respostas dos utilizadores, disponíveis na Internet, a uma pergunta sobre qual o software que recomendavam para apoio à análise de dados. Procurou-se identificar os fatores satisfacientes e insatisfacientes subjacentes às suas recomendações. O estudo revela-se útil como ponto de partida para o monitoramento e melhoria contínua do serviço prestado pelo software, tendo assim uma aplicação prática. De igual modo, a nível teórico, a abordagem do modelo bifatorial aplicado ao uso de software, reforça a ideia de que não basta procurar os fatores de satisfação para que o utilizador recomende um serviço. É necessário identificar os fatores insatisfacientes porque estes resultam da experiência negativa, que se revela marcante no momento do utilizar recomendar ou não um determinado serviço.

D7 Moduli Stabilization: The Tadpole Menace

description: D7-brane moduli are stabilized by worldvolume fluxes, which contribute to the D3-brane tadpole. We calculate this contribution in the Type IIB limit of F-theory compactifications on Calabi-Yau four-folds with a weak Fano base, and are able to prove a no-go theorem for vast swathes of the landscape of compactifications. When the genus of the curve dual to the D7 worldvolume fluxes is fixed and the number of moduli grows, we find that the D3 charge sourced by the fluxes grows faster than 7/16 of the number of moduli, which supports the Tadpole Conjecture of Ref.~\cite{Bena:2020xrh}. Our lower bound for the induced D3 charge decreases when the genus of the curves dual to the stabilizing fluxes increase, and does not allow to rule out a sliver of flux configurations dual to high-genus high-degree curves. However, we argue that most of these fluxes have very high curvature, which is likely to be above the string scale except on extremely large (and experimentally ruled out) compactification manifolds.

Beyond cusp anomalous dimension from integrability

description: We study the first sub-leading correction $O((\ln s)^0)$ to the cusp anomalous dimension in the high spin expansion of finite twist operators in ${\cal N}=4$ SYM theory. Since this approximation is still governed by a linear integral equation (derived already from the Bethe Ansatz equations in a previous paper), we finalise it better in order to study the weak and strong coupling regimes. In fact, we emphasise how easily the weak coupling expansion can be obtained, confirms the known four loop result and predicts the higher orders. Eventually, we pay particular attention to the strong coupling regime showing agreement and predictions in comparison with string expansion; speculations on the 'universal' part (upon subtracting the collinear anomalous dimension) are brought forward.
