description: Freeze-out conditions in Heavy Ion Collisions are generally determined by comparing experimental results for ratios of particle yields with theoretical predictions based on applications of the Hadron Resonance Gas model. We discuss here how this model dependent determination of freeze-out parameters may eventually be replaced by theoretical predictions based on equilibrium QCD thermodynamics.

description: Deep Learning (DL) is gaining rapid popularity in various domains, such as computer vision, speech recognition, etc. With the increasing demands, large clusters have been built to develop DL models (i.e., data preparation and model training). DL jobs have some unique features ranging from their hardware requirements to execution patterns. However, the resource management techniques applied in existing DL clusters have not yet been adapted to those new features, which leads to resource inefficiency and hurts the performance of DL jobs. We observed three major challenges brought by DL jobs. First, data preparation jobs, which prepare training datasets from a large volume of raw data, are memory intensive. DL clusters often over-allocate memory resource to those jobs for protecting their performance, which causes memory underutilization in DL clusters. Second, the execution time of a DL training job is often unknown before job completion. Without such information, existing cluster schedulers are unable to minimize the average Job Completion Time (JCT) of those jobs. Third, model aggregations in Distributed Deep Learning (DDL) training are often assigned with a fixed group of CPUs. However, a large portion of those CPUs are wasted because the bursty model aggregations can not saturate them all the time. In this thesis, we propose a suite of techniques to eliminate the mismatches between DL jobs and resource management in DL clusters. First, we bring the idea of memory disaggregation to enhance the memory utilization of DL clusters. The unused memory in data preparation jobs is exposed as remote memory to other machines that are running out of local memory. Second, we design a two-dimensional attained-service-based scheduler to optimize the average JCT of DL training jobs. This scheduler takes the temporal and spatial characteristics of DL training jobs into consideration and can efficiently schedule them without knowing their execution time. Third, we define a shared model aggregation service to reduce the CPU cost of DDL training. Using this service, model aggregations from different DDL training jobs are carefully packed together and use the same group of CPUs in a time-sharing manner. With these techniques, we demonstrate that huge improvements in resource efficiency and job performance can be obtained when the cluster’s resource management matches with the features of DL jobs.

description: We present a comprehensive study of the periodic variations observed in OGLE I-band light curves of SMC Be/X-ray binaries, discovering new optical periodicities in 9 systems. We find that these periodicities derive from a number of mechanisms, notably disturbance of the decretion disk on the orbital period of the system, and aliased non-radial pulsations. We develop metrics that allow these mechanisms to be distinguished on the basis of the shape of the folded optical light curve, and use these metrics to categorise the periodicities present in \sim 50 SMC binary systems. We conclude that extreme care must be taken in the interpretation of the OGLE light curves since only around 30% of the periodicities present can be unambiguously attributed to orbital periods.

The Pursuit of Wisdom in Education

Publisher: name: Education
Year: 2011

description: Bibliography: p. 393-418
description: Wisdom is widely recognized as a precious good. In recent times, efforts have been made to incorporate the pursuit of wisdom into schools through Philosophy for Children (P4C) and Contemplative Education programming. However, such initiatives to reform education have missed their mark in various ways. Modern scholarship has struggled to come to terms with the meaning of wisdom and its significance in the field of education. This thesis examines the importance of pursuing wisdom in schools by turning to ancient and medieval sources for clarification concerning the nature of wisdom. I argue that our current emphasis on the development of rigorous critical-analytic thinking skills, on assessment, and accountability in education have negatively impacted the ability of schools to foster an environment in which both students and teachers might pursue wisdom. I therefore recommend not evermore aggressive work and efficiency in education for the purpose of ensuring our global competitiveness, but rather the institutional promotion of periods of leisure or schole in the school day in which students and teachers might begin to learn what it means to pursue wisdom as the ancients did: namely, as the practice of “immortalizing” and as “the art of dying."

Open timelike curves violate Heisenberg's uncertainty principle

description: Toy models for quantum evolution in the presence of closed timelike curves (CTCs) have gained attention in the recent literature due to the strange effects they predict. The circuits that give rise to these effects appear quite abstract and contrived, as they require non-trivial interactions between the future and past which lead to infinitely recursive equations. We consider the special case in which there is no interaction inside the CTC, referred to as an open timelike curve (OTC), for which the only local effect is to increase the time elapsed by a clock carried by the system. Remarkably, circuits with access to OTCs are shown to violate Heisenberg's uncertainty principle, allowing perfect state discrimination and perfect cloning of coherent states. The model is extended to wave-packets and smoothly recovers standard quantum mechanics in an appropriate physical limit. The analogy with general relativistic time-dilation suggests that OTCs provide a novel alternative to existing proposals for the behaviour of quantum systems under gravity.
Mechanistic studies and manipulation of the enzymes in sialic acid and pseudaminic acid biosynthesis

Publisher: name: University of British Columbia
Year: 2010

description: The Neisseria meningitidis sialic acid synthase (NeuB) catalyzes the metal-dependent condensation of N-acetylmannosamine (ManNAc) and phosphoenolpyruvate (PEP) to generate N-acetylneuraminic acid. This work describes the synthesis and characterization of the first potent inhibitor of sialic acid synthase, a tetrahedral intermediate analogue as a mixture of stereoisomers at the key tetrahedral center. Inhibition studies demonstrate that one stereoisomer binds more tightly than the other. An X-ray crystallographic analysis of the NeuB•inhibitor•Mn²⁺ complex solved to a resolution of 1.75 Å shows that the more tightly bound stereoisomer bears a (2R)-configuration. This suggests that the tetrahedral intermediate formed in the NeuB reaction also bears a (2R)-configuration. This analysis demonstrates that the active site metal serves as a source of nucleophilic water and delivers it to the si face of the oxocarbenium intermediate to generate a tetrahedral intermediate with a (2R)-configuration. The flagellin proteins in pathogenic bacteria such as Campylobacter jejuni and Helicobacter pylori are heavily glycosylated with the nine-carbon α-keto acid, pseudaminic acid. A key step in pseudaminic acid biosynthesis has been shown to involve the generation of 6-deoxy-AltdiNAc from its nucleotide-linked form, UDP-6-deoxy-AltdiNAc, by the action of a hydrolase that cleaves the glycosidic bond and releases UDP. This thesis describes the first characterization of a UDP-6-deoxy-AltdiNAc hydrolase, namely PseG (Cj1312) from C. jejuni. The activity of this enzyme is independent of the presence of divalent metal ions, and the values of the catalytic constants were found to be kcat = 27 s⁻­­­­­¹ and KM = 174 µM. The enzyme was shown to hydrolyze the substrate with an overall inversion of stereochemistry at C1 and to utilize a C-O bond cleavage mechanism during catalysis. The last part of the thesis describes the engineering of C. jejuni. We demonstrated that by feeding non-motile mutant C. jejuni bacteria with a neutral azide-labeled pseudaminic acid precursor, the mutants regained the ability to generate functional azido-bearing flagella and their motility was restored. The presence of the azido-pseudaminic acid on the surface of the flagella provides a bioorthogonal chemical handle that can be used to modify the flagellar proteins and to engineer bacteria for further studies.

description: We study field-effect transistors realized from VO2 nanobeams with HfO2 as the gate dielectric. When heated up from low to high temperatures, VO2 undergoes an insulator-to-metal transition. We observe a change in conductance (~ 6 percent) of our devices induced by gate voltage when the system is in the insulating phase. The response is reversible and hysteretic, and the area of hysteresis loop becomes larger as the rate of gate sweep is slowed down. A phase lag exists between the response of the conductance and the gate voltage. This indicates the existence of a memory of the system and we discuss its possible origins.

O desdém pelo campo receptivo esteve presente nos estudos ligados ao universo cinematográfico que priorizavam, quase que exclusivamente, fatores externos a ele. A imposição de um olhar de inspiração estruturalista, enclausurara o trabalho artístico e a abordagem de seus próprios campos que, na verdade, são campos da experiência. No entanto, mesmo a experiência de se assistir a um filme só pode efetivamente ser considerada levando-se em conta a relação interativa entre espectador e obra, ou seja, com base no seu aspecto comunicativo-receptivo.

description: The magnetic field-pressure-temperature (H-P-T) phase diagram for first order antiferromagnetic (AFM) to ferromagnetic (FM) transition in Fe49(Rh0.93Pd0.07)51 has been constructed using resistivity measurements under simultaneous application of magnetic field (up to 8 Tesla) and pressure (up to 20 kbar). Temperature dependence of resistivity (ρ-T) shows that with increasing pressure, the width of the transition and the extent of hysteresis decreases whereas with the application of magnetic field it increases. Consistent with existing literature the first order transition temperature (TN) increases with the application of external pressure (~ 7.3 K/ kbar) and decreases with magnetic field (~ - 12.8 K/Tesla). Exploiting these opposing trends, resistivity under simultaneous application of magnetic field and pressure is used to distinguish the relative effect of temperature, magnetic field and pressure on disorder broadened first order transition. For this a set of H and P values are chosen for which TN (H1, P1) = TN (H2, P2). Measurements for such combinations of H and P show that the temperature dependence of resistivity is similar i.e. the broadening (in temperature) of transition as well as extent of hysteresis remains independent of H and P. The transition width decreases exponentially with increasing temperature. Isothermal magnetoresistance measurement under various constant pressure show that even though the critical field required for AFM-FM transition depends on applied pressure, the hysteresis as well as transition width (in magnetic field) both remains independent of pressure, consistent with our conclusions drawn from ρ-T measurements.

description: Pretende-se discutir neste artigo a importância da regulamentação da actividade de Lobbying em Portugal. A actividade de Lobbying permite uma melhor apresentação e esclarecimento sobre questões mais complicadas da vida social, trazendo informação pertinente e argumentos válidos para a discussão política e para a procura daquilo que é o interesse público. O Lobbying é, acima de tudo, uma importante ferramenta competitiva num conflito de interesses, sendo que quanto mais transparente e regulado mais são será o sistema democrático. Observar esta actividade enquanto expressão de um interesse permite-nos perceber que uma estratégia de Lobbying é fulcral na influência de políticas públicas, pois o seu principal objectivo é exactamente influenciar proactivamente os agentes políticos. Estando regulado nos países anglo-saxónicos, na União Europeia, e ainda noutros países de diferentes continentes, importa pois perceber a importância que a regulamentação do Lobbying traria a Portugal e as vantagens que a democracia portuguesa poderia beneficiar. Este é essencialmente um estudo exploratório, onde também é utilizada metodologia quantitativa (inquéritos por questionário a agências de comunicação.) e qualitativa (entrevistas a profissionais da área). Através do estudo efectuado conclui-se que a regulamentação actividade de Lobbying é um assunto que não é pacífico junto dos profissionais do sector da Comunicação, apesar de ser perceptível a sua existência (mesmo não regulamentada) e ser uma actividade necessária para o bom funcionamento da Democracia.

description: O século XX trouxe inúmeros avanços e inovações em vários campos. Um dos mais notáveis foi, possivelmente, a Internet, que mudou o Mundo de forma indelével, aproximando pessoas e nações de forma nunca antes vista. Graças à Internet a informação propaga-se quase à velocidade da luz, e a notícia passa a ser transmitida ao microsegundo em vez de diariamente. Um rumor ou informação que seja publicado na Internet ou nas redes sociais pode auxiliar ou destruir a reputação de uma empresa, reputação esta que demorou anos ou décadas a construir. Dada a rapidez do tráfego de informação, torna-se imperativo que os novos profissionais estejam a par das últimas inovações e tecnologias nas áreas da comunicação. Muitas empresas usam o Google +, o Facebook ou o LinkedIn como ferramenta de relações públicas para melhorar a sua presença junto do público aumentar a sua competitividade com outras empresas. É também necessário que estes profissionais as saibam usar de forma proficiente. Só assim poderão tirar o melhor partido possível das novas ferramentas que têm ao seu alcance, usando-as para o benefício da empresa e também para que possam gerir de forma eficiente a forma como a empresa se apresenta ao público e também minimizar mais facilmente danos resultantes de uma crise. Adicionalmente, o novo milénio trouxe também novas preocupações e objetivos para empresários e administradores. Se outrora a função dos últimos era maximizar o lucro a todo o custo, hoje em dia assiste-se à ascensão da Responsabilidade Social das Empresas (RSE) que se coaduna com os conceitos de comércio justo e ética empresarial. Este paper pretende, portanto, analisar não só o impacto da RSE na reputação das empresas, mas também o papel que esta e a ética desempenham no estabelecimento da reputação de uma organização e na forma como estas afetam a perceção da empresa por parte do público. Vão ser também apresentados exemplos práticos de empresas que usaram a Ética e RSE a seu favor bem como de empresas que viram a sua reputação destruída por não terem antecipado o efeito e a influência que estes fatores teriam no seu volume de negócios.

description: The Hartree-Fock-Bogoliubov approximation is very useful for treating both long- and short-range correlations in finite quantum fermion systems, but it must be extended in order to describe detailed spectroscopic properties. One problem is the symmetry-breaking character of the HFB approximation. We present a general and systematic way to restore symmetries and to extend the configuration space using pfaffian formulas for the many-body matrix elements. The advantage of those formulas is that the sign of the matrix elements is unambiguously determined. It is also helpful to extend the space of configurations by constraining the HFB solutions in some way. A powerful method for finding these constrained solutions is the gradient method, based on the generalized Thouless transformation. The gradient method also preserves the number parity of the Bogoliubov transformation, which facilitates the application of the theory to systems with odd particle number.

description: Background:

Understanding the mechanisms by which genes control and regulate complex quantitative traits during periods of fluctuating resources remains a challenging and uncertain task in photosynthesis studies. Most studies have focused on the structure of photosynthesis, the photosynthetic response under stress, or the genetic mechanisms involved in photosynthetic effects and neglected the interactive genetic mechanism that governs various traits through significant quantitative trait loci (QTLs). Results In this study, we have developed a differential dynamic system that enables the identification of QTLs based on the photosynthetic phenotypic and genotypic data under varying levels of light intensity gradients. The framework not only allows for the assessment of the direct effects of QTLs on phenotypes but also captures how they influence interactions among phenotypes as light intensities change. We have analyzed the genetic effects and genetic variance, visualized the genetic network associated with photosynthesis interactions, and validated the effectiveness and stability of the DDS framework. Pivotal QTLs were identified individually to uncover the process and pattern of interaction. Through functional annotation, we made an intriguing discovery that seemingly unimportant QTLs can still have significant genetic effects on phenotypic changes through their regulation with other QTLs. Conclusions This finding emphasizes the significance of considering the interactive genetic architecture when seeking to understand the genetic interaction mechanism of photosynthesis in natural populations of woody plants. Moreover, our research provides a novel framework that can be extended to explore the interactive genetic architecture among organisms, contributing to a deeper understanding of stress resistance mechanisms in woody plants.

description: Com a proliferação dos novos media a comunicação de crise tornou-se mais importante que nunca. Estes podem ajudar ou prejudicar as organizações dependendo da maneira como são usados, no entanto uma monitorização e controle constante dos mesmos, proporcionam um controle da imagem e reputação da organização. Actualmente, as organizações não podem excluir o recurso aos novos sociais media como uma ferramenta fundamental nas comunicações das empresas com os seus clientes, isto porque estes estão a tornar-se no canal preferido para a disseminação de informação e comunicação. Vivemos num mundo globalizado, onde as informações adquiridas modificam atitudes e comportamentos, as redes sociais transformaram a forma como as pessoas e as empresas comunicam entre si, pois permitem a partilha de informação em tempo real, com pessoas fisicamente distantes, provocaram uma mudança na forma e na velocidade de acesso à informação e ao conhecimento, assim como a interacção entre as pessoas. O problema lida com a relação entre as organizações e os seus públicos, num contexto de mediação através do computador, logo a utilização dos novos media como uma nova forma de diálogo entre as organizações e os stakeholders, permitindo o escrutínio imediato das organizações por parte dos seus públicos (ativo e interveniente), que poderão originar consequências numa situação de crise, colocando em risco a reputação e até a própria organização. Com a participação dos novos media, as empresas podem ter de alterar ou modificar a abordagem de decisões tomadas, de modo a prevenir potenciais situações de crise ou em caso de crise que tem como origem os novos media, tomarem medidas adequadas, minimizando os danos em termos de imagem. Na comunicação de crise, existe a necessidade de melhorar a eficiência da utilização dos novos media sociais no sentido de ampliar o conteúdo informacional, aproveitando os recursos disponibilizados pela ferramenta, de modo a reduzir erros, na actualização do conteúdo com o intuito de melhorar a sua eficácia para os diversos públicos para os quais está destinado.

description: O impacto social da revolução proporcionada pela internet traz enormes desafios à prática das Relações Públicas. As modificações que ocorrem todos os dias na esfera social, política e económica têm um impacto direto sobre o dia-a-dia do profissional de Comunicação, que necessita de compreender e dominar a dinâmica das Redes Sociais e as ferramentas desta nova realidade. Esta é, de facto, uma questão central para a construção de relações, não só através da comunicação mediada pela tecnologia, mas toda aquela que, direta ou indiretamente, é por ela impactada. Este artigo apresenta uma reflexão sobre a nova realidade a que as Relações Públicas têm de se adaptar e sobre a função que os seus profissionais desempenham nesta realidade de comunicação bidirecional. Vamos analisar os desafios e as novas dinâmicas que fazem parte do dia-a-dia dos profissionais de Comunicação. Numa fase seguinte a importância, cada vez mais crescente e inevitável, do online na estratégia das Relações Públicas. Apresentaremos ainda os aspetos táticos relevantes para implementar boas práticas online de Relações Públicas e as enormes potencialidades que oferecem à comunicação como um todo.

description: Exciton luminescence of a CdSe quantum dot (QD) inserted in a ZnSe nanowire is strongly influenced by the dark exciton states. Because of the small size of these QDs (2-5nm), exchange interaction between hole and electron is highly enhanced and we measured large energy splitting between bright and dark exciton states ($ΔE\in [4, 9.2 ]$ meV) and large spin flip rates between these states. Statistics on many QDs showed that this splitting depends on the QD size. Moreover, we measured an increase of the spin flip rate to the dark states with increasing energy splitting. We explain this observation with a model taking into account the fact that the exciton-phonon interaction depends on the bright to dark exciton energy splitting as well as on the size and shape of the exciton wave function. It also has consequences on the exciton line intensity at high temperature.

description: All-loop Finite Unified Theories (FUTs) are very interesting N = 1 supersymmetric Grand Unified Theories (GUTs) realising an old field theory dream, and moreover have a remarkable predictive power due to the required reduction of couplings. Based on this theoretical framework phenomenologically consistent FUTs have been constructed. Here we review two FUT models based on the SU(5) gauge group, which can be seen as special, restricted and thus very predictive versions of the MSSM. We show that from the requirement of correct prediction of quark masses and other experimental constraints a light Higgs-boson mass in the range M_h ~ 121 - 126 GeV is predicted, in striking agreement with recent experimental results from ATLAS and CMS. The model furthermore naturally predicts a relatively heavy spectrum with colored supersymmetric particles above ~ 1.5 TeV in agreement with the non-observation of those particles at the LHC.

description: A Connected Dominating Set (CDS) based virtual backbone plays an important role in wireless ad hoc networks for efficient routing and broadcasting. Each node in the network can select some of its 1-hop neighbors as Multi Point Relay (MPR) to cover all its 2-hop neighbors. A MPR based CDS is a promising approach for broadcasting. A node in the CDS consumes more energy and the energy depletes quickly than non dominating nodes. Although previous CDS construction algorithms achieve good results in terms of the size of CDS, a minimum size CDS does not necessarily guarantee an optimal network performance from an energy efficient point of view. In this paper, we propose a distributed algorithm for energy efficient stable MPR based CDS construction to extend the lifetime of ad hoc wireless networks by considering energy and velocity of nodes. We have also implemented route discovery protocol to make use of the CDS nodes to relay route request messages. The simulation results show that our algorithm increases the lifetime up to 25% than previous works and 60% reduction in the route request messages during route discovery process.

description: As tecnologias de informação e comunicação aplicadas à comunicação interna das organizações conferem originalidade e rapidez no acto de comunicação, proporcionando novos métodos e práticas indutoras de participação activa e interacção de comunicação em rede entre os seus diferentes colaboradores. O desenvolvimento da Intranet é um exemplo claro para a dinâmica interna que se espera mais participativa nas organizações, como um decisivo factor para a geração de inovação, conhecimento e espírito de pertença dos seus colaboradores, potenciando e reforçando um clima organizacional positivo e propício ao cumprimento dos objectivos empresariais e seu crescimento sustentado e para a sua cultura e identidade organizacional (Elias e Mascaray, 2003; Aloy et al., 2005; Maurício, 2006; Pinho, 2003; Nestares, 2002; Almeida, 2003; Riel, 1995). O presente estudo centra-se, precisamente, na avaliação dos processos de comunicação interna e monotorização da Intranet da Danone Portugal, empresa que faz parte da multinacional Grupo Danone que tem como conceito central na sua actividade, o saber aliar “o negócio com as pessoas”, sendo considerada desde 2004, pela Revista Exame, como a melhor empresa em Portugal no sector Agro-industrial e classificada como a 16ª melhor empresa para trabalhar em Portugal segundo o Great Place to Work Institute. Pretendeu-se, deste modo, realizar um estudo onde se apurasse o contributo da sua comunicação interna em rede, Intranet, como veículo de participação e envolvimento dos seus colaboradores. Como principais conclusões a que se chegou nesta investigação podemos destacar que se validou a 1 ª hipótese em estudo. No entanto, quanto à 2 ª hipótese, esta só se pode considerar como parcialmente validada, em virtude dos inquiridos entenderem que a Intranet, ainda não lhes permite um nível elevado de participação e interacção, solicitando uma nova fase de aprofundamento das suas potencialidades.
