description: We used data from a prospective study of 300 women attending a sexually transmitted infection clinic in Kingston, Jamaica, to compare participant self-report of recent semen exposure to actual semen exposure measured by prostate-specific antigen in vaginal swabs. Underreporting of semen exposure was significantly more frequent at follow-up than baseline, suggesting the accuracy of reports of sexual behavior may vary over time.

description: Probabilistic graphical models such as Bayesian Networks are one of the most powerful structures known by the Computer Science community for deriving probabilistic inferences. However, modern cognitive psychology has revealed that human decisions could not follow the rules of classical probability theory, because humans cannot process large amounts of data in order to make judgements. Consequently, the inferences performed are based on limited data coupled with several heuristics, leading to violations of the law of total probability. This means that probabilistic graphical models based on classical probability theory are too limited to fully simulate and explain various aspects of human decision making. Quantum probability theory was developed in order to accommodate the paradoxical findings that the classical theory could not explain. Recent findings in cognitive psychology revealed that quantum probability can fully describe human decisions in an elegant framework. Their findings suggest that, before taking a decision, human thoughts are seen as superposed waves that can interfere with each other, influencing the final decision. In this work, we propose a new Bayesian Network based on the psychological findings of cognitive scientists. We made experiments with two very well known Bayesian Networks from the literature. The results obtained revealed that the quantum like Bayesian Network can affect drastically the probabilistic inferences, specially when the levels of uncertainty of the network are very high (no pieces of evidence observed). When the levels of uncertainty are very low, then the proposed quantum like network collapses to its classical counterpart.

description: We examine the potential of the $ep\toν_{e}qγX$ and $ep\toν_{e}qZX$ processes to search for the anomalous couplings of $WWγ$ and $WWZ$ vertices at the LHeC with the electron beam energy of $E_{e}=60$ GeV and $E_{e}=140$ GeV. The difference of maximum and minimum bounds on the anomalous couplings, ($δΔκ_γ$, $δλ_γ$) and ($δΔκ_{Z}$, $δλ_{Z}$) are obtained as ($0.990$, $0.122$) and ($0.362$, $0.012$) without electron beam polarization at the beam energy of $E_{e}=140$ GeV for an integrated luminosity of $L_{int}=100$ fb$^{-1}$, respectively. With the possibility of $e-$beam polarization, we obtain more improved results as ($0.975$, $0.118$) and ($0.285$, $0.009$) for ($δΔκ_γ, δλ_γ$) and ($δΔκ_{Z}, δλ_{Z}$), respectively. The results are found to be comparable with the current experimental limits obtained from two-parameter analysis at the lepton and hadron colliders. It is found that the limits on the anomalous couplings ($Δκ_{Z}$, $λ_{Z}$) through the process $ep\toν_{e}qZX$ at the LHeC can further improve the current experimental limits.

description: The inverse Rashba-Edelstein effect (IREE) in a two-dimensional electron gas (2DEG) induced by spin pumping from an adjacent ferromagnetic insulator (FI) is investigated theoretically. In particular, spin and current densities in the 2DEG in which both Rashba and Dresselhaus spin-orbit interactions coexist are formulated, and their dependencies on ferromagnetic resonance frequency and orientation of the spin in the FI are clarified. It is shown that spin density diverges when the ratio between the Rashba and Dresselhaus spin-orbit interactions approaches unity, while current density stays finite there. These results can be applied for evaluating spin splitting on the Fermi surface in a 2DEG and designing spintronic devices using IREE.

description: In this paper we present and analyze HSkip+, a self-stabilizing overlay network for nodes with arbitrary heterogeneous bandwidths. HSkip+ has the same topology as the Skip+ graph proposed by Jacob et al. [PODC 2009] but its self-stabilization mechanism significantly outperforms the self-stabilization mechanism proposed for Skip+. Also, the nodes are now ordered according to their bandwidths and not according to their identifiers. Various other solutions have already been proposed for overlay networks with heterogeneous bandwidths, but they are not self-stabilizing. In addition to HSkip+ being self-stabilizing, its performance is on par with the best previous bounds on the time and work for joining or leaving a network of peers of logarithmic diameter and degree and arbitrary bandwidths. Also, the dilation and congestion for routing messages is on par with the best previous bounds for such networks, so that HSkip+ combines the advantages of both worlds. Our theoretical investigations are backed by simulations demonstrating that HSkip+ is indeed performing much better than Skip+ and working correctly under high churn rates.

description: Exposure to alcohol outlets may influence sexual health outcomes at the individual- and community-level. Visiting alcohol outlets facilitates alcohol consumption and exposes patrons to a risky environment and network of potential partners, while presence of alcohol outlets in the community may shift social acceptance of riskier behavior. We hypothesize that living in communities with more alcohol outlets is associated with increased sexual risk.

description: What is necessary to reach net zero emissions in the transport sector on a global level? To keep limiting global warming to 1.5° C within reach, the world has to decarbonise by mid-century, with every sector contributing as much as possible as soon as possible. This paper identifies what has to be done in road transport, aviation, and shipping to achieve net zero emission in the transport sector. For this purpose, it first sets the scene by providing an overview of the origins and impacts of the concept of net zero emissions in international climate policy as well as of the current state and future prospects of global transport emissions using currently available scenarios for low-emission and net zero transport. While for staying below 1.5° C, the basic approach to reducing transport emissions remains unchanged from what has been suggested in the past, the set, intensity and pace of actions as to shift fundamentally. Without first drastically reducing traffic volume and shifting transport demand to low-emission modes, reaching net zero transport will not be feasible: the amount of additional electricity required to fully electrify the sector with renewable energy is otherwise just too huge. After portraying key instruments for achieving net zero emissions in land transport, aviation, and shipping, this paper identifies key barriers for net zero transport. Based on this analysis, the authors recommend the following to be able to move transport to net zero: 1. Adapt Decarbonisation Strategies to Different Transport Sub-sectors 2. Prioritise and Significantly Increase Investment in Zero-/low-carbon Infrastructure 3. Massively Invest in the Development and Roll out of Zero-/low-emission Technologies 4. Focus on a Just Transition to Overcome Social and Political Barriers 5. Increase International Support and Cooperation

description: In this paper, we have successfully identified the triangular-shaped defect structures with stacking fault tetrahedra. These structure often appeared in hard-sphere (HS) crystals grown on a square pattern under gravity. We have, so far, performed Monte Carlo simulations of the HS crystals under gravity. Single stacking faults as observed previously in the HS crystals grown on a flat wall were not seen in the case of square template. Instead, defect structures with triangular appearance in $xz$- and $yz$- projections were appreciable. We have identified them by looking layer by layer. Those structures are surrounded by stacking faults along face-centered cubic (fcc) {111}. Also, we see isolated vacancies and vacancy-interstitial pairs, and we have found octahedral structures surrounded by stacking faults along fcc {111}.

description: Each summer, the IFREMER laboratory of Arcachon monitors, in the scope of an agreement with the Regional Conchological Comity of Arcachon, the reproduction of Pacific oysters in the Arcachon Bay. This monitoring aims to provide oyster farmers with information necessary to the spat collecting: - dates and amount of spawn, - larval development speed, - presence of the most evolved stages in the habitat (close to fixation). Reproduction is monitored from June to September, with plankton being sampled four times a week on different representative sites. Oyster larvae at different stages are counted. At the end of the reproduction period (September-October), larval recruitment on collectors is estimated via the counting of the spats collected, at various collection areas. Furthermore, the results gathered in the framework of the IFREMER “RESCO” network are used to characterise the spawners' maturation in the spring preceding the reproduction period. This report presents the results of the 2013 reproduction season, and their interpretation through old data.
description: Durant chaque saison estivale, le laboratoire IFREMER d'Arcachon réalise, dans le cadre d'une convention avec Comité Régional Conchylicole (CRC) Arcachon-Aquitaine, le suivi de la reproduction des huîtres creuses dans le Bassin d'Arcachon. Ce suivi a pour but de fournir aux ostréiculteurs les informations nécessaires à la mise en oeuvre du captage de naissains : - dates et importance des pontes, - vitesse de développement des larves, - présence dans le milieu des stades les plus évolués (proches de la fixation). Le suivi de la reproduction est réalisé entre juin et septembre, des pêches de plancton étant réalisées quatre fois par semaine dans différents sites représentatifs du Bassin. Les larves d'huîtres aux différents stades y sont dénombrées. A l'issue de la saison de reproduction (octobre-novembre), l'estimation du recrutement larvaire sur les collecteurs est effectuée par comptage des naissains captés sur un certain nombre de collecteurs (tuiles et coupelles) prélevés dans les différents secteurs de captage. Par ailleurs, les résultats obtenus dans le cadre du réseau « RESCO » de l'IFREMER sont utilisés pour caractériser la maturation des géniteurs au cours du printemps précédant la saison de reproduction. Ce rapport présente les résultats de la saison de reproduction 2013, interprétés à la lumière des séries de données anciennes.

description: Let $F$ be a totally real number field and $E/F$ a totally imaginary quadratic extension of $F$. Let $Π$ be a cohomological, conjugate self-dual cuspidal automorphic representation of $GL_n(\mathbb A_E)$. Under a certain non-vanishing condition we relate the residue and the value of the Asai $L$-functions at $s=1$ with rational structures obtained from the cohomologies in top and bottom degrees via the Whittaker coefficient map. This generalizes a result in Eric Urban's thesis when $n = 2$, as well as a result of the first two named authors, both in the case $F = \mathbb Q$.

description: Silicon quantum dot qubits show great promise but suffer from charge noise with a 1/f^αspectrum, where f is frequency and α\lesssim 1. It has recently been proposed that 1/f^αnoise spectra can emerge from a few thermally activated two-level fluctuators in the presence of sub-bath temperature fluctuations associated with a two-dimensional electron gas (2DEG)~\cite{Ahn2021}. We investigate this proposal by doing Monte Carlo simulations of a single Ising spin in a bath with a fluctuating temperature. We find that to obtain noise with a $1/f^α$ spectrum with $alpha \lesssim 1 down to low frequencies, the duration of temperature fluctuations must be comparable to the inverse of the lowest frequency at which the noise is measured. This result is consistent with an analytic calculation in which the fluctuator is a two-state system with dynamics governed by time-dependent switching rates. In this case we find that the noise spectrum follows a Lorentzian at frequencies lower than the inverse of the average duration of the lowest switching rate. We then estimate relaxation times of thermal fluctuations by considering thermal diffusion in an electron gas in a confined geometry. We conclude that temperature fluctuations in a 2DEG sub-bath would require an unphysically long duration to be consistent with experimental measurements of 1/f-like charge noise in quantum dots at frequencies extending well below 1 Hz.

description: In this paper we present the SPICE approach for sparse parameter estimation in a framework that unifies it with other hyperparameter-free methods, namely LIKES, SLIM and IAA. Specifically, we show how the latter methods can be interpreted as variants of an adaptively reweighted SPICE method. Furthermore, we establish a connection between SPICE and the l1-penalized LAD estimator as well as the square-root LASSO method. We evaluate the four methods mentioned above in a generic sparse regression problem and in an array processing application.

description: The history of the Magellanic Clouds is investigated using N-body hydrodynamic simulations where the initial conditions are set by a genetic algorithm. This technique allows us to identify possible orbits for the Magellanic Clouds around the Milky Way, by directly comparing the simulations with observational constraints. We explore the parameter space of the interaction between the Magellanic Clouds and the Milky Way, considering as free parameters the proper motions of the Magellanic Clouds, the virial mass and the concentration parameter ($c$) of the Galactic dark matter halo. The best orbital scenarios presented here are considered with two different sets of parameters for the Milky Way disc and bulge components. The total circular velocity at the Sun's position ($\rm{R_{\odot}}=8.5\,\rm {kpc}$) is directly calculated from the rotation curve of the corresponding Galactic mass model. Our analysis suggests that the Magellanic Clouds have orbited inside the virial radius of the Milky Way for at least $3\,\rm{Gyr}$, even for low mass haloes. However, this is possible only with high values for the concentration parameter ($c\ge20$). In both orbital models presented here, the mutual interaction between the Magellanic Clouds is able to reproduce the observed features of the Magellanic System.

description: Pistachio (Pistacia vera L.) forests support livelihoods in communities within Afghanistan’s Pistachio Belt, a region characterized by extreme poverty and chronic insecurity. In this study, we used ecological data, as well as survey data to characterize standing attributes and resource user perceptions about local pistachio forests and their management. The survey questionnaire was verbally administered to 507 household representatives in remote communities that were chosen from eight districts in northern and northwestern Afghanistan based on accessibility and their location within the Pistachio Belt. Stand density and tree form varied widely between sites and as a function of elevation. Partial harvesting for fuelwood collection was positively correlated with stand density. The survey data also showed that pistachio forests support a variety of livelihood activities among respondents and their households. However, suboptimal nut collection timing and use of damaging nut harvesting methods were widespread with little effort to accommodate natural regeneration. Forest users typically recognized the degraded condition of the pistachio forest and the negative impacts of grazing and fuelwood collection on forest density. Respondents also recognized the impacts of nut collection practices, fuelwood collection, and grazing on forest regeneration status. These results suggest that efforts to sustainably manage pistachio forests must recognize considerable variation within and between communities regarding forest physical condition, accustomed uses by associated communities, and existing or potential mechanisms regulating forest uses. All of these necessitate context-specific forest management planning. We discuss challenges inherent to collecting baseline data needed for planning multiple-use community-based natural resources management in highly insecure environments.
A frailty-contagion model for multi-site hourly precipitation driven by atmospheric covariates

description: Accurate stochastic simulations of hourly precipitation are needed for impact studies at local spatial scales. Statistically, hourly precipitation data represent a difficult challenge. They are non-negative, skewed, heavy tailed, contain a lot of zeros (dry hours) and they have complex temporal structures (e.g., long persistence of dry episodes). Inspired by frailty-contagion approaches used in finance and insurance, we propose a multi-site precipitation simulator that, given appropriate regional atmospheric variables, can simultaneously handle dry events and heavy rainfall periods. One advantage of our model is its conceptual simplicity in its dynamical structure. In particular, the temporal variability is represented by a common factor based on a few classical atmospheric covariates like temperatures, pressures and others. Our inference approach is tested on simulated data and applied on measurements made in the northern part of French Brittany.

description: A gestão de pessoas deve atuar como um componente estratégico visando a utilização planejada de abordagens próprias aos colaboradores da instituição com a finalidade de implementação e junção das estratégias da organização. É a busca pela retenção, desenvolvimento, engajamento e motivação dos funcionários para que satisfaçam as suas necessidades como seres humanos e proporcionem assim a satisfação das necessidades da organização e dos clientes. Na presente pesquisa, considerou-se que uma ação vinculada à perspectiva de gestão de pessoas promoveria a satisfação das necessidades dos funcionários fazendo com que eles se mostrassem mais engajados e motivados no trabalho. Neste caso, o entendimento foi de que, a partir do momento em que a instituição fornece o meio para que o colaborador se qualifique, ele se sentirá mais motivado e engajado. Nessa perspectiva, o objetivo central dessa dissertação consistiu em verificar se os docentes do Instituto Federal de Educação, Ciência e Tecnologia do Norte de Minas Gerais (IFNMG) sentiam-se motivados e engajados após a oportunidade de afastamento para qualificação, oferecida pelo órgão, e o retorno do servidor às suas atividades. Para que essa situação fosse verificada, procedeu-se o estudo das teorias de engajamento no trabalho propostas por Kahn (1990) e Schaufeli et al. (2002), e o estudo das teorias a respeito da motivação no trabalho propostas por Maslow (Teoria da Hierarquia das Necessidades), Alderfer (Teoria ERG), Vroom (Teoria da Expectativa), McClelland (Teoria das Necessidades), Adams (Teoria da Equidade), Herzberg (Teoria dos Dois Fatores), Locke e Latham (Teoria da Fixação de Metas). O estudo foi feito em uma abordagem qualitativa, sendo do tipo exploratório e utilizando como formas de investigação a pesquisa de campo, bibliográfica e o estudo de caso. Os dados foram coletados por meio de análise documental, pesquisa bibliográfica e entrevistas com os docentes da instituição. Os resultados indicaram que os professores do IFNMG que se afastaram para mestrado ou doutorado, beneficiados pela ação do órgão, sentem-se mais engajados e motivados no trabalho após o retorno às suas atividades. Indicaram ainda que a obtenção do título acadêmico é essencial tanto para vida pessoal quanto profissional dos docentes, e que o afastamento para qualificação é um fator diferencial e está atrelado à questão da motivação no trabalho.

description: The Lorentz reciprocal theorem -- that is used to study various transport phenomena in hydrodynamics -- is violated in chiral active fluids that feature odd viscosity with broken time-reversal and parity symmetries. Here we show that the theorem can be generalized to fluids with odd viscosity by choosing an auxiliary problem with the opposite sign of the odd viscosity. We demonstrate the application of the theorem to two categories of microswimmers. Swimmers with prescribed surface velocity are not affected by odd viscosity, while those with prescribed active forces are. In particular, a torque-dipole can lead to directed motion.

description: In these three lectures, I overview the theoretical framework of the flavour physics and CP violation. The first lecture is the introduction to the flavour physics. Namely, I give theoretical basics of the weak interaction. I follow also some historical aspect, discovery of the CP violation, phenomenological studies of charged and neutral currents and the success of the GIM mechanism. In the second lecture, I describe the flavour physics and CP violating phenomena in the Standard Model (SM). I also give the latest experimental observation of the CP Violation at the B factories and the LHC and discuss its interpretation. In the third lecture, I discuss the on-going search of the signals beyond SM in the flavour physics and also the future prospects.

description: The use of native species for timber plantations in the tropics has lately gained interest. Recent studies have shown that native tree plantations can have greater economic, and ecological benefits than non-native plantations. Facilitative nutritional interactions with nitrogen-fixing trees are a common practice used in hopes of enhancing nitrogen input. Dalbergia retusa and Terminalia amazonia are two neotropical species frequently used for timber extraction. In order to understand these species belowground interactions, we worked on 33 plots of the T. amazonia and D. retusa mixtures in the Agua Salud Project Native Species plantations in Panama. The objective of this study was to assess if soil biochemical properties under T. amazonia trees might be influenced by D. retusa in these mixtures. For this, soil samples were collected and analyzed for nitrogen pools, extractable cations and selected phosphorus constituents. Our results showed that nutrient concentrations were not significantly different below D. restusa and T. amazonia trees. Nonetheless, temporal and physicochemical characteristics of the plantation might be influencing the tree performance and should be considered for a better understanding of the nutrient dynamics in native tree plantations.
Monitoring sexual behaviour in general populations: a synthesis of lessons of the past decade
Creators: name: Cleland, J

description: This supplement contains selected papers from a workshop on the measurement of sexual behaviour in the era of HIV/AIDS held at the London School of Hygiene and Tropical Medicine in September 2003. The focus was on low and middle income countries, where the majority of HIV infections occur. The motive for holding such a meeting is easy to discern. As the AIDS pandemic continues to spread and as prevention programmes are scaling up, the need to monitor trends in sexual risk behaviours becomes ever more pressing. Behavioural data are an essential complement to biological evidence of changes in HIV prevalence or incidence. Biological evidence, though indispensable, is by itself insufficient for policy and programme guidance. AIDS control programmes need to be based on monitoring of not only trends in infections but also of trends in those behaviours that underlie epidemic curtailment or further spread.
Small Total-Cost Constraints in Contextual Bandits with Knapsacks, with Application to Fairness

description: We consider contextual bandit problems with knapsacks [CBwK], a problem where at each round, a scalar reward is obtained and vector-valued costs are suffered. The learner aims to maximize the cumulative rewards while ensuring that the cumulative costs are lower than some predetermined cost constraints. We assume that contexts come from a continuous set, that costs can be signed, and that the expected reward and cost functions, while unknown, may be uniformly estimated -- a typical assumption in the literature. In this setting, total cost constraints had so far to be at least of order $T^{3/4}$, where $T$ is the number of rounds, and were even typically assumed to depend linearly on $T$. We are however motivated to use CBwK to impose a fairness constraint of equalized average costs between groups: the budget associated with the corresponding cost constraints should be as close as possible to the natural deviations, of order $\sqrt{T}$. To that end, we introduce a dual strategy based on projected-gradient-descent updates, that is able to deal with total-cost constraints of the order of $\sqrt{T}$ up to poly-logarithmic terms. This strategy is more direct and simpler than existing strategies in the literature. It relies on a careful, adaptive, tuning of the step size.

description: We have succeeded in growing single crystals of SmPt2Si2 and have performed electrical resistivity, magnetization and specific heat measurements. The magnetic susceptibility shows that SmPt2Si2 is an Ising magnet with the crystalline-electric-field ground state of Jz=+-3/2. We have found the existence of two magnetically ordered states, i.e., an antiferromagnetically (AFM) ordered phase (I) setting in at TN=5.1 K and a field-induced magnetization plateau phase (II). In the phase I, unlike the usual AFM states, a pronounced Curie-Weiss contribution remains in magnetic susceptibility, indicating the existence of "partially disordered" Sm ions. Largely enhanced Sommerfeld-coefficient (350 mJ/K2mol) in the phase I can be attributed to formation of Kondo sublattice with heavy quasiparticles in the partially disordered Sm ions. These findings may reflect substantial magnetic frustrations inherent in SmPt2Si2.

description: Schwinger boson mean field theory is a powerful approach to study frustrated magnetic systems which allows to distinguish long range magnetic orders from quantum spin liquid phases, where quantum fluctuations remain strong up to zero temperature. In this work, we use this framework to study the Heisenberg model on the Kagome lattice with up to third nearest neighbour interaction and Dzyaloshinskii-Moriya (DM) antisymmetric exchange. This model has been argued to be relevant for the description of transition metal dichalcogenide bilayers in certain parameter regimes, where spin liquids could be realized. By means of the projective symmetry group classification of possible ansätze, we study the effect of the DM interaction at first nearest neighbor and then compute the $J_2$-$J_3$ phase diagram at different DM angles. We find a new phase displaying chiral spin liquid characteristics up to spin $S=0.5$, indicating an exceptional stability of the state.

description: It is one of the most challenging tasks at the Large Hadron Collider and at a future Linear Collider not only to observe physics beyond the Standard Model, but to clearly identify the underlying new physics model. In this paper we concentrate on the distinction between two different supersymmetric models, the MSSM and the NMSSM, as they can lead to similar low energy spectra. The NMSSM adds a singlet superfield to the MSSM particle spectrum and simplifies embedding a SM-like Higgs candidate with the measured mass of about 125.5 GeV. In parts of the parameter space the Higgs sector itself does not provide sufficient indications for the underlying model. We show that exploring the gaugino/higgsino sectors could provide a meaningful way to distinguish the two models. Assuming that only the lightest chargino and neutralino masses and polarized cross sections $e^+e^-\to \tildeχ^0_i\tildeχ^0_j$, $\tildeχ^+_i\tildeχ^-_j$ are accessible at the linear collider, we reconstruct the fundamental MSSM parameters $M_1$, $M_2$, $μ$, $\tanβ$ and study whether a unique model distinction is possible based on this restricted information. Depending on the singlino admixture in the lightest neutralino states, as well as their higgsino or gaugino nature, we define several classes of scenarios and study the prospects of experimental differentiation.
