description: The decisive role violence has played in the ordering of the Third World cannot be ignored or consigned to the past. Accordingly, we argue for a more systematic and determined attention to the connections between the devastation unleashed by colonialism, imperialism, and other forms of large-scale violence in the post-independence periods. In contradistinction to situating violence in and against the Third World as a backdrop of incomplete modernization, we recognize that its proper location is in the larger dynamics of racialized and colonial international relations. The articles in this volume address these dynamics of violence.

OBJECTIVES: Pay-it-forward incentives effectively promote hepatitis B virus (HBV) and hepatitis C virus (HCV) testing among men who have sex with men (MSM) by offering free testing and donation opportunities. This study aims to explore the interaction between pay-it-forward incentives and recreational drug use on HBV and HCV testing uptake among Chinese MSM. METHODS: We pooled data from two pay-it-forward studies that aimed to promote dual HBV and HCV testing among MSM in Jiangsu, China. We explored factors associated with hepatitis testing uptake in the two study groups and examined the interaction between pay-it-forward incentives and recreational drug use on hepatitis testing uptake. RESULTS: Overall, 511 MSM participated in these two studies, with 265 participants in the pay-it-forward incentives group and 246 participants in the standard-of-care group. Among these participants, 59.3% in the pay-it-forward incentive group and 24.8% in the standard-of-care group received dual HBV and HCV testing, respectively. In the pay-it-forward incentives group, participants who used recreational drugs in the past 12 months (adjusted OR (AOR)=1.83, 95% CI 1.09 to 3.06) were more likely to receive dual HBV and HCV testing, compared with those who never used recreational drugs, whereas in the standard-of-care group, those who used recreational drugs were less likely to receive dual HBC and HCV testing (AOR=0.38, 95% CI 0.18 to 0.78). MSM with higher community connectedness (AOR=1.10, 95% CI 1.00 to 1.21) were also more likely to receive hepatitis testing with pay-it-forward incentives. There was a synergistic interaction on both the multiplicative (ratio of ORs=4.83, 95% CI 1.98 to 11.7) and additive scales (the relative excess risk of interaction=2.97, 95% CI 0.56 to 5.38) of pay-it-forward incentives and recreational drug use behaviours on dual HBV and HCV testing uptake among MSM. CONCLUSION: Pay-it-forward incentives may be particularly useful in promoting hepatitis testing among MSM who use recreational drugs.

description: The increasing demands on computational lithography and imaging in the design and optimization of lithography processes necessitate rigorous modeling of EUV light diffracted from the mask. Traditional EMF solvers are inefficient for large-scale technology problems, while deep neural networks rely on a huge amount of expensive rigorously simulated or measured data. To overcome these constraints, we explore the potential of physics-informed neural networks (PINN) as a promising solution for addressing complex optical problems in EUV lithography and accurate modeling of light diffraction from typical reflective EUV masks, which include an absorber on top of a multilayer. Lithography simulations are done for 3D masks with line-space patterns and contact holes. Based on the obtained results, the perspectives of an accelerated PINN-based EMF solver as an alternative solution to traditional methods are discussed. The capabilities of the established PINNs approach to simulate typical 3D mask effects including non-telecentricities, shifts of the best focus position, and image blur are demonstrated. The coupling of the predicted diffraction spectrum with image simulations enables the evaluation of PINN performance in terms of relevant lithographic metrics. The results of modeling near- and far-field diffraction using PINN showcase a good performance in terms of convergence behavior, stability, and accuracy. Process windows predicted by PINN completely overlap the ones rigorously simulated by the numerical solver. The outcomes of our study demonstrate a real benefit of PINN: differently from numerical solvers, once trained, generalized PINN can simulate light scattering in several milliseconds without re-training and independently of problem complexity. As a result, PINN demonstrates a significant speed up (up to x10000) compared to the Waveguide simulation of the same instance.

description: We report on the first direct observation of a transition from a Tomonaga-Luttinger liquid to a Fermi liquid behavior in potassium intercalated mats of single wall carbon nanotubes (SWCNT). Using high resolution photoemission spectroscopy an analysis of the spectral shape near the Fermi level reveals a Tomonaga-Luttinger liquid power law scaling in the density of states for the pristine sample and for low dopant concentration. As soon as the doping is high enough to fill bands of the semiconducting tubes a distinct transition to a bundle of only metallic SWCNT with a scaling behavior of a normal Fermi liquid occurs. This can be explained by a strong screening of the Coulomb interaction between charge carriers and/or an increased hopping matrix element between the tubes.

description: A novel tertiary phosphine oxide containing two quinaldinyl substituents has been synthesized according to adapted literature procedures. Its coordination properties toward Cu(I) and Ag(I) were investigated and the resulting complexes were analyzed by single crystal X-ray diffraction. Multinuclear complexes are formed, wherein the ligand is bridging across two metal centers. Though for the silver complex, no argentophilic interactions are present. The copper complex was characterized further by multinuclear NMR spectroscopy at variable temperatures.

description: We have developed an economical and efficient method for the synthesis of medicinally and synthetically important indole-based triarylmethanes by using indoles and benzhydrols in the presence of propylphosphonic anhydride (T3P®). This methodology is an alternate approach for the C–C bond formation with good to excellent yields. In this T3P-mediated dehydration approach, the by-product is highly soluble in water, so that it can be done at larger scale also. In addition to that this efficient protocol has several advantages such as mild reaction conditions, short reaction time and operational simplicity. We have successfully synthesized pyrrole, imidazothiadiazole and imidazolo pyridine based triarylmethanes also.

description: Cross-lingual word embeddings aim to bridge the gap between high-resource and low-resource languages by allowing to learn multilingual word representations even without using any direct bilingual signal. The lion's share of the methods are projection-based approaches that map pre-trained embeddings into a shared latent space. These methods are mostly based on the orthogonal transformation, which assumes language vector spaces to be isomorphic. However, this criterion does not necessarily hold, especially for morphologically-rich languages. In this paper, we propose a self-supervised method to refine the alignment of unsupervised bilingual word embeddings. The proposed model moves vectors of words and their corresponding translations closer to each other as well as enforces length- and center-invariance, thus allowing to better align cross-lingual embeddings. The experimental results demonstrate the effectiveness of our approach, as in most cases it outperforms state-of-the-art methods in a bilingual lexicon induction task.

description: The infinite reduction of couplings is a tool to consistently renormalize a wide class of non-renormalizable theories with a reduced, eventually finite, set of independent couplings, and classify the non-renormalizable interactions. Several properties of the reduction of couplings, both in renormalizable and non-renormalizable theories, can be better appreciated working at the regularized level, using the dimensional-regularization technique. We show that, when suitable invertibility conditions are fulfilled, the reduction follows uniquely from the requirement that both the bare and renormalized reduction relations be analytic in epsilon=D-d, where D and d are the physical and continued spacetime dimensions, respectively. In practice, physically independent interactions are distinguished by relatively non-integer powers of epsilon. We discuss the main physical and mathematical properties of this criterion for the reduction and compare it with other equivalent criteria. The leading-log approximation is solved explicitly and contains sufficient information for the existence and uniqueness of the reduction to all orders.

description: Based on the recently introduced black-bounce spacetimes, we shall consider the construction of the related spherically symmetric thin-shell traversable wormholes within the context of standard general relativity. All of the really unusual physics is encoded in one simple parameter $a$ which characterizes the scale of the bounce. Keeping the discussion as close as possible to standard general relativity is the theorist's version of only adjusting one feature of the model at a time. We shall modify the standard thin-shell traversable wormhole construction, each bulk region now being a black-bounce spacetime, and with the physics of the thin shell being (as much as possible) derivable from the Einstein equations. Furthermore, we shall apply a dynamical analysis to the throat by considering linearized radial perturbations around static solutions, and demonstrate that the stability of the wormhole is equivalent to choosing suitable properties for the exotic material residing on the wormhole throat. The construction is sufficiently novel to be interesting, and sufficiently straightforward to be tractable.

description: Given a flat metric one may generate a local Hamiltonian structure via the fundamental result of Dubrovin and Novikov. More generally, a flat pencil of metrics will generate a local bi-Hamiltonian structure, and with additional quasi-homogeneity conditions one obtains the structure of a Frobenius manifold. With appropriate curvature conditions one may define a curved pencil of compatible metrics and these give rise to an associated non-local bi-Hamiltonian structure. Specific examples include the F-manifolds of Hertling and Manin equipped with an invariant metric. In this paper the geometry supporting such compatible metrics is studied and interpreted in terms of a multiplication on the cotangent bundle. With additional quasi-homogeneity assumptions one arrives at a so-called weak $\F$-manifold - a curved version of a Frobenius manifold (which is not, in general, an F-manifold). A submanifold theory is also developed.

description: Galaxy clusters will distort the pattern of temperature anisotropies in the microwave background via gravitational lensing. We create lensed microwave background maps using clusters drawn from numerical cosmological simulations. A distinctive dipole-like temperature fluctuation pattern is formed aligned with the underlying microwave temperature gradient. For a massive cluster, the characteristic angular size of the temperature distortion is a few arcminutes and the characteristic amplitude a few micro-Kelvin. We demonstrate a simple technique for estimating the lensing deflection induced by the cluster; microwave background lensing measurements have the potential to determine the mass distribution for some clusters with good accuracy on angular scales up to a few arcminutes. Future high-resolution and high-sensitivity microwave background maps will have the capability to detect lensing by clusters; we discuss various systematic limitations on probing cluster masses using this technique.

description: We review the present status of the experimental and theoretical developments in the field of strangeness in nuclei and neutron stars. We start by discussing the $\bar K N$ interaction, that is governed by the presence of the $Λ(1405)$. We continue by showing the two-pole nature of the $Λ(1405)$, and the production mechanisms in photon-, pion-, kaon-induced reactions as well as proton-proton collisions, while discussing the formation of $\bar K NN$ bound states. We then move to the theoretical and experimental analysis of the properties of kaons and antikaons in dense nuclear matter, paying a special attention to kaonic atoms and the analysis of strangeness creation and propagation in nuclear collisions. Next, we examine the $ϕ$ meson and the advances in photoproduction, proton-induced and pion-induced reactions, so as to understand its properties in dense matter. Finally, we address the dynamics of hyperons with nucleons and nuclear matter, and the connection to the phases of dense matter with strangeness in the interior of neutron stars.

description: In this paper, we studied systematically the semileptonic decays $\bar{B}_s \to K^{(*)} \ell^+ \ell^-$ with $l^-=(e^-,μ^-,τ^-)$ by using the perturbative QCD (PQCD) and the "PQCD+Lattice" factorization approach, respectively. We first evaluated all relevant form factors $F_i(q^2)$ in the low $q^2$ region using the PQCD approach, and we also take the available Lattice QCD results at the end point $q^2_{max}$ as additional inputs to improve the extrapolation of the form factors to the high $q^2$ region. We calculated the branching ratios and other twelve kinds of physical observables. From our studies, we find the following points: (a) for $ \bar{B}_s \to K l^+ l^-$ decays, the PQCD and "PQCD+Lattice" predictions for branching ratios (BRs) ${\cal B}(\bar{B}_s \to K l^+ l^-)$, the ratios of the BRs $R_K^{eμ}$ and $R_K^{μτ}$, and the longitudinal polarization asymmetry of the leptons $P_L$ agree well within errors; (b) the PQCD and "PQCD+Lattice" predictions for the CP averaged branching ratio ${\cal B}(\bar{B}_s \to K^* μ^+ μ^-)$ are $(3.17^{+0.95}_{-0.78})\times 10^{-8}$ and $(2.48^{+0.56}_{-0.50})\times 10^{-8}$ respectively, which agree well with the LHCb measured value $(2.9\pm 1.1) \times 10^{-8}$ and the light-cone sum rule (LCSR) prediction; (c) for the ratios $R_{K^\ast}^{eμ}$ and $R_{K^\ast}^{μτ}$, the PQCD and "PQCD+Lattice" predictions agree well with each other and have a small error less than $10\%$; (d) for the direct CP asymmetries ${\cal A}_{CP}$ of all considered decay modes, they are always very small as expected: less than $5\%$ in magnitude; and (e) for the angular observables $P_{1,2,3}$ and $P^\prime_{4,5,6,8}$ , our theoretical predictions for each kind of lepton are consistent within errors. We believe that above predictions could be tested by future LHCb and Belle-II experiments.

description: A key aspect of the design of evolutionary and swarm intelligence algorithms is studying their performance. Statistical comparisons are also a crucial part which allows for reliable conclusions to be drawn. In the present paper we gather and examine the approaches taken from different perspectives to summarise the assumptions made by these statistical tests, the conclusions reached and the steps followed to perform them correctly. In this paper, we conduct a survey on the current trends of the proposals of statistical analyses for the comparison of algorithms of computational intelligence and include a description of the statistical background of these tests. We illustrate the use of the most common tests in the context of the Competition on single-objective real parameter optimisation of the IEEE Congress on Evolutionary Computation (CEC) 2017 and describe the main advantages and drawbacks of the use of each kind of test and put forward some recommendations concerning their use.

description: We investigate the spin-current linear response conductivity tensor to an electric field in a paramagnetic two dimensonal electron gas with both Rashba and Dresselhaus spin-orbit coupling in the weak scattering regime. In the ususal case where both spin-orbit-split bands are occupied, we find that the spin-Hall conductivity depends only on the sign of the difference in magnitude of the Rashba and Dresselhaus coupling strengths except within a narrow window where both coupling strengths are equal. We also find a new effect in which a spin current is generated in the direction of the driving field whenever the Dresselhaus spin-orbit coupling is nonzero. We discuss experimental implications of this finding taking into account the finite mobility and typical parameters of current samples and possible experimental set ups for its detection.

description: The new Alma Mater Society (AMS) Student Union Building (SUB) aims to incorporate functionality as one of the primary buildings at the heart of campus with the promotion and practicing of sustainable living during its operation. This paper explores the methods and the effects of the addition of a public display board to meet this goal. The current projection of the new SUB includes such a display, but its implementation has yet to be decided. The scope of this paper includes a triple bottom line assessment (TBLA) of the following two products of display boards, both of which are currently offered on the market: Samsung’s UE46A Display and Sony’s Bravia EX720 Display. These product models have been selected based on economic, environmental, and social benefits, along with feasibility of either implementing a single large display in the atrium, multiple small displays, or a hybrid of the two structures. This paper will also explore recommendations based on a survey conducted of 100 random University of British Columbia (UBC) students at the existing SUB. Primary research was completed in order to evaluate how effective students felt the display board could be in attaining the goal of raising awareness towards sustainable living, and what specific content would be most effective on the display to meet this goal. Based on the analysis of obtained primary and secondary data, the recommendation that the display board should be a hybrid of both small displays, and a single large display has been made. Furthermore, the display board should exhibit UBC’s PULSE Energy live feed as a visual data representation, a public comment board accessible wirelessly or via the internet, and general information relating to sustainability and global climate change.

description: We have observed a narrow state near 2.32 GeV/c^2 in the inclusive Ds+ pi0 invariant mass distributionfrom e+e- annihilation data at energies near 10.6 GeV. The observed width is consistent with the experimental resolution. The small intrinsic width and the quantum numbers of the final state indicate that the decay violates isospin conservation. The state has natural spin-parity and the low mass suggests a JP=0+ assignment. The data sample corresponds to an integrated luminosity of 91 fb-1 recorded by the BABAR detector at the PEP2 asymmetric-energy e+e- storage ring.

description: Corruption politics have received little attention in human geography. We offer a critical geography of corruption as an alternative to economistic framings that take corruption as an objective set of deviant practices mostly besetting states in the Global South. Instead, we theorize corruption as a historically shifting, subjective discourse about the abuse of entrusted power. Geographic and cognate disciplinary approaches reveal how corruption narratives become politicized and yoked to symbolic, material, and territorial regimes of power. We suggest that recent theories of urban informality provide a revealing lens into the ethico-politics and territorial struggles of contemporary capitalism across the North and South.

description: Polaritons enable the resonant coupling of excitons and photons to vibrations in the application-relevant super high frequency (SHF, 3-30 GHz) domain. We introduce a novel platform for coherent optomechanics based on the coupling of exciton-polaritons and electrically driven SHF longitudinal acoustic phonons confined within the spacer region of a planar Bragg microcavity. An intrinsic property of the microcavity platform is the back-feeding of phonons via reflections at the sample boundaries, which enables frequency x quality factors products exceeding 10^14 Hz as well as huge modulation amplitudes of the optical transition energies (up to 8 meV). We show that the modulation is dominated by the phonon-induced energy shifts of the excitonic polariton component, thus leading to an oscillatory transition between the regimes of weak and strong light-matter coupling. These results open the way for polariton-based coherent optomechanics in the non-adiabatic, side-band-resolved regime of coherent control.

description: Context In its best-practices recommendation, the Inter-Association Task Force for Preventing Sudden Death in Secondary School Athletics Programs urged all high schools to have a certified athletic trainer (AT) on staff. Despite the recommendation, many high schools lack the medical services of an AT. Objective To examine the barriers that athletic directors (ADs) face in hiring ATs in public high schools and in providing medical coverage for their student-athletes. Design Qualitative study. Setting Semistructured telephone interviews. Patients or Other Participants Twenty full-time public high school ADs (17 men, 3 women) from various geographical regions of the United States (6 North, 4 South, 4 Midwest, 6 West) participated. Data saturation guided the total number of participants. Data Collection and Analysis We completed telephone interviews guided by a semistructured questionnaire with all participants. Interviews were recorded and transcribed verbatim. Multiple-analyst triangulation and peer review were included as steps to establish data credibility. We analyzed the data using the principles of the general inductive approach. Results We identified 3 themes. Lack of power represented the inability of an AD to hire an AT, which was perceived to be a responsibility of the superintendent and school board. Budget concerns pertained to the funding allocated to specific resources within a school, which often did not include an AT. Nonbudget concerns represented rural locations without clinics or hospitals nearby; misconceptions about the role of an AT, which led to the belief that first-aid–trained coaches are appropriate medical providers; and community support from local clinics, hospitals, and volunteers. Conclusions Many ADs would prefer to employ ATs in their schools; however, they perceive that they are bound by the hiring and budgeting decisions of superintendents and school boards. Public school systems are experiencing the consequences of national budget cuts and often do not have the freedom to hire ATs when other school staff are being laid off.

description: Abstract: Control is typically seen as a dyadic relationship, meaning that there is a controller who exercises control over another person, the controllee. Until now, research in the field of IS project control mainly focused on the controller perspective, covering aspects like control choices and its effects on project performance. This unilateral research focus has led to gaps regarding the controllee’s perspective on control mechanisms - neglecting influence of the controllee’s resulting behavior on control efficiency and effectiveness. The ongoing research presented in this paper therefore aims at investigating the factors that determine congruence between controller and controllee in an IS project setting. For this purpose, a quantitative vignette study will be conducted as an approach that is able to combine the advantages of both qualitative and quantitative research methods. Potential findings include a considerable impact of a controllee’s congruence on compliance with IS project control mechanisms. Maximizing the level of congruence could improve IS project control efficiency and effectiveness and thus help increasing IS project success.

description: In this paper, we simultaneously determine the optimal sensor precision and the observer gain, which achieves the specified accuracy in the state estimates. Along with the unknown observer gain, the formulation parameterizes the scaling of the exogenous inputs that correspond to the sensor noise. Reciprocal of this scaling is defined as the sensor precision, and sparseness is achieved by minimizing the $l_1$ norm of the precision vector. The optimization is performed with constraints guaranteeing specified accuracy in state estimates, which are defined in terms of $\mathcal{H}_2$ or $\mathcal{H}_{\infty}$ norms of the error dynamics. The results presented in this paper are applied to the linearized longitudinal model of an F-16 aircraft.
Duality in Left-Right Symmetric Seesaw Mechanism

description: We consider type I+II seesaw mechanism, where the exchanges of both right-handed neutrinos and isotriplet Higgs bosons contribute to the neutrino mass. Working in the left-right symmetric framework and assuming the mass matrix of light neutrinos $m_ν$ and the Dirac-type Yukawa couplings to be known, we find the triplet Yukawa coupling matrix $f$, which carries the information about the masses and mixing of the right-handed neutrinos. We show that in this case there exists a duality: for any solution $f$, there is a dual solution $\hat{f}=m_ν/v_L-f$, where $v_L$ is the VEV of the triplet Higgs. Thus, unlike in pure type I (II) seesaw, there is no unique allowed structure for the matrix $f$. For $n$ lepton generations the number of solutions is $2^n$. We develop an exact analytic method of solving the seesaw non-linear matrix equation for $f$.

description: This report investigates the feasibility of installing electricity harvesting exercise equipment as part of a display in the atrium of the new Student Union Building. This display’s purpose is to increase energy awareness, fit the exercise-needs of students, and produce renewable electricity. Three companies that provide electricity harvesting exercise equipment that are investigated in this report are ReRev, PlugOut, and Human Dynamo. After performing a triple bottom-line assessment, it is concluded that installation of electricity harvesting exercise equipment would promote physical fitness, be reasonable to implement, and work well with other displays in encouraging energy conservation awareness at the new Student Union Building. The PlugOut visCycle is chosen as the best option for implementation as it is economical, environmentally friendly, easily installable, and students surveyed have shown interest in stationary bikes over the elliptical machines or the human dynamo system. This report recommends that two PlugOut visCycles be purchased for integration into a display at the atrium of the new Student Union Building that allows students to race, keep track of the electricity they have produced, and keep track of the amount of carbon emissions that they have offset. A recommendation is also made that discounts at the new building’s vendors based on electricity generated be offered to students as an incentive. However, contacting vendors for particular discounts has been determined to be beyond the scope of this paper. Overall, this paper predicts a significant social impact, at a price much lower than other displays with similar goals such as the Pavogen step system currently being investigated for implementation. Surveys show a strong student interest in the implementation of the recommendations of this report, supporting its predicted success.

description: One can solve the Jeans equation analytically for equilibrated dark matter structures, once given two pieces of input from numerical simulations. These inputs are 1) a connection between phase-space density and radius, and 2) a connection between velocity anisotropy and density slope, the α-βrelation. The first (phase-space density v.s. radius) has been analysed through several different simulations, however the second (α-βrelation) has not been quantified yet. We perform a large set of numerical experiments in order to quantify the slope and zero-point of the α-βrelation. When combined with the assumption of phase-space being a power-law in radius this allows us to conclude that equilibrated dark matter structures indeed have zero central velocity anisotropy, central density slope of α_0 = -0.8, and outer anisotropy of approximately β_\infinity = 0.5.

"O Último Albardeiro": notas históricas e  etnográficas sobre um ofício em extinção
Creators: name: António Luis Pereira
Publisher: name: Revista Memória Rural
Year: 2023

description: Neste artigo propõe-se uma aproximação histórica a uma das profissões tradicionais outrora mais conhecida e procurada no mundo rural e urbano. O albardeiro esteve presente nas cidades, nas vilas e nas aldeias durante séculos, até que a revolução dos transportes e as alterações processadas no mundo rural o transformam num mester obsoleto. O motor de combustão interna, primeiro, a mecanização agrícola e as transformações operadas no mundo rural a partir de meados do século XX, depois, traçaram um destino sem futuro para estes mestres de um saber-fazer tão ancestral como a domesticação do cavalo, do burro, da égua, do macho ou do boi. Com a substituição destes animais de trabalho, de tração e de carga, por máquinas mais rápidas, mais operacionais, mas também mais poluidoras, as oficinas dos albardeiros, paulatinamente, foram encerrando portas. Em pouco mais  de três décadas a profissão entrou em completa decadência. Na atualidade talvez se possa contar pelos dedos das mãos os artesãos ativos que ainda laboram no nosso país. Os que ainda fazem obra bem podem ser considerados como os últimos resistentes de uma arte antiga, mas já absolutamente moribunda. Um desses resistentes chama-se Carlos dos Santos Almeida e trabalha em Torre de Dona Chama, no concelho de Mirandela. Foi por ele e pela sua resiliência que resolvemos escrever este  artigo. É também a partir do seu testemunho pessoal e história de vida que ambicionamos deixar um registo histórico, antropológico e etnográfico para memória futura. O registo possível sobre a obra e os artefactos produzidos pelos atuais e ancestrais mestres desta já praticamente extinta profissão.
