description: The physics aims at the proposed high-energy $e^+e^-$ collider CLIC pose challenging demands on the performance of the detector system. Precise hit-time tagging, an excellent spatial resolutions, and a low mass are required for the vertex and tracking detectors. To meet these requirements, an all-silicon vertex and tracking detector system is foreseen, for which a broad R&D programme on a variety of novel silicon detector technologies is being pursued. For the ultra-low mass vertex detector, different hybrid technologies with innovative sensor concepts and interconnection techniques are explored. For the large-scale tracking detector, the focus of the R&D lies on monolithic HV-MAPS and HR-CMOS technologies. This contribution gives an overview of the ongoing activities with a focus on monolithic technologies for the CLIC tracking detector. Recent results from laboratory and test-beam measurement campaigns of the ATLASpix_Simple and the CLICTD sensor prototypes are presented.

description: Adam is a commonly used stochastic optimization algorithm in machine learning. However, its convergence is still not fully understood, especially in the non-convex setting. This paper focuses on exploring hyperparameter settings for the convergence of vanilla Adam and tackling the challenges of non-ergodic convergence related to practical application. The primary contributions are summarized as follows: firstly, we introduce precise definitions of ergodic and non-ergodic convergence, which cover nearly all forms of convergence for stochastic optimization algorithms. Meanwhile, we emphasize the superiority of non-ergodic convergence over ergodic convergence. Secondly, we establish a weaker sufficient condition for the ergodic convergence guarantee of Adam, allowing a more relaxed choice of hyperparameters. On this basis, we achieve the almost sure ergodic convergence rate of Adam, which is arbitrarily close to $o(1/\sqrt{K})$. More importantly, we prove, for the first time, that the last iterate of Adam converges to a stationary point for non-convex objectives. Finally, we obtain the non-ergodic convergence rate of $O(1/K)$ for function values under the Polyak-Lojasiewicz (PL) condition. These findings build a solid theoretical foundation for Adam to solve non-convex stochastic optimization problems.

description: O estudo visa compreender a representação dos agricultores familiares em espaços institucionais de participação social através de uma pesquisa junto aos Conselhos Municipais de Desenvolvimento Rural e Grupo Gestor do Território Sudoeste do Paraná. Esses espaços, oriundos do processo de descentralização das instituições do Estado e da aposta na aproximação da sociedade civil da gestão estatal, determinam um processo diferenciado de representação protagonizados pelos representantes dos diferentes grupos sociais. A representação é analisada a partir da representatividade e da capacidade de intervenção dos representantes nos espaços. A pesquisa demonstra que diferentes configurações dos espaços alteram o processo de representação a partir da distinção dos perfis dos representantes, do relacionamento dos representantes com os representados e de como os espaços institucionais de participação social se identificam com as conformações associativas. O processo de representação agricultores familiares não é condicionada pela escala destes espaços, mas pela relação entre a escala e a forma como se estruturam as práticas associativas no território.-------------------------------------------This study aims to present a research on the family farmers’ representation at institutional social participation spaces. Data were obtained from City Councils for Rural Development and Management Group of Southwest Territory of Paraná, which are institutional spaces originated from decentralization process in an effort to develop civil society participation in state management. Such spaces determine an unusual representation process where protagonists are social groups representatives. Representation is analysed considering the representativeness and the representatives ability to intervene in the spaces. This study has demonstrated that different configurations of space change the representation process related to the following topics: profile distinction among representatives; forms of relationship among the representatives and the represented people; and the way that occur identification between institutional spaces and local associative conformity. Therefore the family farmers’ representation process is not determined by the ratio of these spaces but it is determined by the correlation between this ratio and the local associative arrangements.

description: This work presents retQSS, a novel methodology for efficient modeling and simulation of particle systems in reticulated meshed geometries. On the simulation side, retQSS profits from the discrete-event nature of Quantized State System (QSS) methods, which enable efficient particle tracking algorithms that are agnostic of the application domain. On the modeling side, retQSS relies on the standardized Modelica modeling language, yielding compact and elegant specifications of hybrid (continuous/discrete) dynamic systems. Combined together, these features offer a sound, general-purpose framework for modeling and simulation of particle systems. We show how the state-events that arise when particles interact with a reticulated mesh are seamlessly translated into easily tractable time-events. The latter can substantially improve simulation performance in scenarios where discontinuities dominate the computational demand. We showcase the flexibility of our approach by addressing four case studies arising from different application domains. Performance studies revealed that retQSS can perform similarly to, and even outperform, well-known domain-specific particle simulation toolkits while offering a clear and sound accuracy control interface.

description: O desenvolvimento da agricultura e da pecuária na Amazônia tem resultado na expansão dos desmatamentos, o que contribui para emissão de gases de efeito estufa na atmosfera e redução da biodiversidade. A evolução dos desmatamentos realizada pelos produtores rurais é condicionada por características das famílais produtoras e pelo ambiente socioeconômico. O objetivo desse estudo foi identificar os condicionantes de desmatamentos nos principais pólos de produção agropecuária familiar no estado do Acre. Foi utilizado o modelo econométrico logit multinomial para essa avaliação. Os resultados obtidos demonstram que maior disponibilidade de mão-de-obra familiar, acesso a crédito, maior patrimônio, maior ocorrência de contratação de trabalho e titulação definitiva dos lotes de terra são fatores causais de maior desmatamento e que maior tamanho do lote e maior nível de consciência ambiental por parte dos produtores são fatores que atuam para a menor proporção de terra desmatada nas pequenas propriedades. Os resultados mostram que melhoria na renda e riqueza das famílias não tem resultado em maior preservação das matas nativas nas regiões estudadas, o que indica que políticas de melhoria de renda e qualidade de vida devem ser acompanhadas de medidas que favoreçam a conservação dos recursos naturais, especialmente a redução dos desmatamentos.----------------------------------------------The development of agricultural and cattle production has addressed larger deforestation in the Brazilian Amazon, and it lead to greenhouse gas emissions and to biodiversity loss. The increase in the deforestation made by settlers is linked by factors related to household features and microeconomic environment. The objective of this study was to identify the determinant factors for deforestation in main region of household agricultural production in the state of Acre, Brazilian Amazon. The methodology is based on multinomial logistic econometric model. The results show that household labor, access to credit, farmer wealth, hired labor and land tenure favor the deforestation, while greater farm size and environmental-consciousness reduce deforestation.

description: In this paper, we consider stochastic reaction-diffusion equations with super-linear drift on the real line $\mathbb{R}$ driven by space-time white noise. A Freidlin-Wentzell large deviation principle is established by a modified weak convergence method on the space $C([0,T], C_{tem}(\mathbb{R}))$. Obtaining the main result in this paper is challenging due to the setting of unbounded domain, the space-time white noise, and the superlinear drift term without dissipation. To overcome these difficulties, the special designed norm on $C([0,T], C_{tem}(\mathbb{R}))$, one order moment estimates of the stochastic convolution and two nonlinear Gronwall-type inequalities play an important role.

description: O presente artigo propõe uma reflexão sobre o enfoque convencional de desenvolvimento da região denominada de Metade Sul do Rio Grande do Sul, tomando como referência uma comunidade situada na APA do Ibirapuitã, no município de Rosário do Sul. As abordagens atuais, apoiadas em indicadores como PIB per capta, Valor Adicionado Fiscal e geração de postos de trabalho, consideram a região como pouco desenvolvida. Entre as estratégias utilizadas para reversão desse quadro destacam-se a expansão das modernas lavouras empresarias de arroz e soja e o fomento aos empreendimentos no ramo florestal. Assim, a pergunta central desse artigo é sobre a capacidade dessas estratégias em promover verdadeiramente o “desenvolvimento” da metade sul do RS. O estudo destaca os possíveis impactos das estratégias convencionais de desenvolvimento na complexa situação sócio-ambiental da região e sugere a necessidade de aprofundar os conhecimentos sobre as especificidades locais, considerando os princípios de sustentabilidade.------------------------------------------------This paper proposes a reflection about the troubles with actual development approach used in the southern half region in the Rio Grande do Sul state. The case study use as reference a community located in the APA do Rio Ibirapuitã at Rosário do Sul County. The actual approaches using GDP per capita, Value Added Tax and job generation, consider the region as poorly developed. Among the strategies used to reversal of this framework the increase of rice and soybean crop production and forest crop are used. Thus, the central question of this article is these strategies in fact to support the "development" of the southern half of the RS. The study highlights the potential impact of conventional development strategies in the complex socio-environmental region situation and suggests more investigation to recognize specific location situation, considering the principles of sustainability.
Minor element behavior in the INCO CRED process
Creators: name: Qin, Guoming
Publisher: name: University of British Columbia
Year: 2009

description: In LNCO's Copper Refinery Electrowinning Department (CRED) the copper sulfide residue containing precious metals (referred as the first stage cake), is subjected to an oxidative pressure leach. The leach - referred as second stage leaching, produces a copper sulfate solution and basic copper sulfate. The basic copper sulfate is releached with spent electrolyte from copper electrowinning containing sulfuric acid to produce impure copper sulfate solution and a precious metals residue. A sample of first stage cake from INCO CRED was shipped to UBC and treated under second stage leaching conditions. The minor element behavior in the process was the objective of the study. The minor elements include cobalt, iron, arsenic, antimony, bismuth, selenium, tellurium and tin. Four important factors that might affect the behavior of minor elements were investigated: Cu/Acid ratio in the feed, Cu/S ratio in the feed, impurity levels in the feed and degree of oxidation. Four series of experiments were performed with filtrate solutions and solid residues analyzed by ICP scan for chemical compositions. Selenium was the minor element of greatest interest due to the difficulty in removing Se from the CRED impure leach solution. Selenium species if present will contaminate copper cathodes and therefore must be removed. The two principal forms of selenium in the CRED streams are believed to be selenite (SeIV) and selenate (SeVI), respectively. INCO CRED had a great concern about selenium speciation in the second stage leaching, which will help to understand the behavior of selenium better and remove it more efficiently. A method for selenium analysis was developed, which was based on Atomic Fluorescence Spectrometry with Hydride Generation (AFS-HG). A pretreatment process was applied to suit the samples in the project and eliminate interferences in Se analysis caused by sulfate and cations. This method was initially applied to samples generated in the UBC lab work. In addition, some samples were taken from INCO CRED plant and analyzed by this method.

description: AIDS adalah kumpulan gejala penyakit yang merupakan hasil manifestasi dari pelemahan sistem imun pada manusia dengan agen etiologis berupa HIV. Walaupun dengan angka kasus baru dan kematian yang meningkat setiap tahunnya, terapi standar yang diberikan saat ini, yaitu obat antiretrovirus (ART), tidak mampu menghancurkan HIV secara menyeluruh. Maka dari itu, sebuah inovasi terapi baru dibutuhkan, yaitu dengan sel T CAR ganda yang merupakan modifikasi dari CAR generasi ketiga. Tinjauan pustaka kali ini akan berfokus dalam menelisik potensi sel T CAR ganda lebih lanjut sebagai imunoterapi terhadap HIV-AIDS. Dalam sebuah studi preklinik, sel T CAR ganda yang memiliki reseptor berupa CD4 menunjukkan hasil yang menjanjikan dalam usaha menangani HIV-AIDS. Pada kondisi terstimulasi antigen maupun tidak, sel T CAR ganda memperlihatkan kemampuan proliferasi dan kesintasannya dalam jangka panjang yang lebih baik dibandingkan dengan kelompok kontrol. Sel T CAR ganda tersebut dimodifikasi lebih lanjut agar dapat mengekspresikan C34-CXCR4 yang mampu menghambat internalisasi dari HIV. Implikasinya, sel T CAR ganda tersebut mampu mengurangi viremia akut secara signifikan dibandingkan dengan kelompok kontrol. Dengan demikian, sel T CAR CD4 ganda berpotensi sebagai imunoterapi terhadap HIV-AIDS. Diharapkan tinjauan pustaka ini mampu dikembangkan lebih lanjut hingga dapat diimplementasikan secara klinis dalam pasien HIV-AIDS.

description: Metric learning is an important problem in machine learning. It aims to group similar examples together. Existing state-of-the-art metric learning approaches require class labels to learn a metric. As obtaining class labels in all applications is not feasible, we propose an unsupervised approach that learns a metric without making use of class labels. The lack of class labels is compensated by obtaining pseudo-labels of data using a graph-based clustering approach. The pseudo-labels are used to form triplets of examples, which guide the metric learning. We propose a probabilistic loss that minimizes the chances of each triplet violating an angular constraint. A weight function, and an orthogonality constraint in the objective speeds up the convergence and avoids a model collapse. We also provide a stochastic formulation of our method to scale up to large-scale datasets. Our studies demonstrate the competitiveness of our approach against state-of-the-art methods. We also thoroughly study the effect of the different components of our method.

description: The primary aim of this article is to extensively study female occupant kinematics and muscle activations in vehicle maneuvers potentially occurring in precrash situations and with different seat belt configurations. The secondary aim is to provide validation data for active human body models (AHBMs) of female occupants in representative precrash loading situations. Front seat female passengers wearing a 3-point seat belt, with either standard or pre-pretensioning functionality, were subjected to multiple autonomously carried-out lane change and lane change with braking maneuvers while traveling at 73 km/h. This article quantifies the head center of gravity and T1 vertebra body (T1) linear and rotational displacements. This article also includes surface electromyography (EMG) data collected from 38 muscles in the neck, torso, and upper and lower extremities, all normalized by maximum voluntary contraction (MVC). The raw EMG data were filtered, rectified, and smoothed. Separate Wilcoxon signed-rank tests were performed on EMG onset and amplitude as well as peak displacements of head and T1 considering 2 paired samples with the belt configuration as an independent variable. Significantly smaller lateral and forward displacements for head and T1 were found with the pre-pretensioner belt versus the standard belt (P P The presented results from female passengers complement the previously published results from male passengers subjected to the same loading scenarios. The data provided in this article can be used for validation of AHBMs of female occupants in both sagittal and lateral loading scenarios potentially occurring prior to a crash. Additionally, our results show that a pre-pretensioner belt decreases muscle activation onset and amplitude as well as forward and lateral displacements of head and T1 compared to a standard belt, confirming previously published results.

description: Using a multi-phase field model, we examine how particle deformability, which is a proxy for cell stiffness, affects motility induced phase separation (MIPS). We show that purely repulsive deformable, i.e., squishy, cells phase separate more effectively than their rigid counterparts. This can be understood as due to the fact that deformability increases the effective duration of collisions. In addition, the dense regions become increasingly disordered as deformability increases. Our results contextualize the applicability of MIPS to biological systems and have implications for how cells in biological systems may self-organize

description: Continuing previous work reported in an earlier paper [L.M. Burko, A.I. Harte, and E. Poisson, Phys. Rev. D 65, 124006 (2002)] we calculate the self-force acting on a point scalar charge in a wide class of cosmological spacetimes. The self-force produces two types of effect. The first is a time-changing inertial mass, and this is calculated exactly for a particle at rest relative to the cosmological fluid. We show that for certain cosmological models, the mass decreases and then increases back to its original value. For all other models except de Sitter spacetime, the mass is restored only to a fraction of its original value. For de Sitter spacetime the mass steadily decreases. The second effect is a deviation relative to geodesic motion, and we calculate this for a charge that moves slowly relative to the dust in a matter-dominated cosmology. We show that the net effect of the self-force is to push on the particle. We show that this is not an artifact of the scalar theory: The electromagnetic self-force acting on an electrically charged particle also pushes on the particle. The paper concludes with a demonstration that the pushing effect can also occur in the context of slow-motion electrodynamics in flat spacetime.

description: The emergence of quasiparticles in quantum many-body systems underlies the rich phenomenology in many strongly interacting materials. In the context of doped Mott insulators, magnetic polarons are quasiparticles that usually arise from an interplay between the kinetic energy of doped charge carriers and superexchange spin interactions. However, in kinetically frustrated lattices, itinerant spin polarons - bound states of a dopant and a spin-flip - have been theoretically predicted even in the absence of superexchange coupling. Despite their important role in the theory of kinetic magnetism, a microscopic observation of these polarons is lacking. Here we directly image itinerant spin polarons in a triangular lattice Hubbard system realised with ultracold atoms, revealing enhanced antiferromagnetic correlations in the local environment of a hole dopant. In contrast, around a charge dopant, we find ferromagnetic correlations, a manifestation of the elusive Nagaoka effect. We study the evolution of these correlations with interactions and doping, and use higher-order correlation functions to further elucidate the relative contributions of superexchange and kinetic mechanisms. The robustness of itinerant spin polarons at high temperature paves the way for exploring potential mechanisms for hole pairing and superconductivity in frustrated systems. Furthermore, our work provides microscopic insights into related phenomena in triangular lattice moiré materials.

description: We study a class of matrix function algebras, here denoted $\mathcal{T}^{+}(\mathcal{C}_n)$. We introduce a notion of point derivations, and classify the point derivations for certain finite dimensional representations of $\mathcal{T}^{+}(\mathcal{C}_n)$. We use point derivations and information about $n \times n$ matrices to show that every $\mathcal{T}^{+}(\mathcal{C}_n)$-valued derivation on $\mathcal{T}^{+}(\mathcal{C}_n)$ is inner.

description: In this work, we demonstrate high performance indium-tin-oxide (ITO) transistors with the channel thickness down to 1 nm and ferroelectric Hf0.5Zr0.5O2 as gate dielectric. On-current of 0.243 A/mm is achieved on sub-micron gate-length ITO transistors with a channel thickness of 1 nm, while it increases to as high as 1.06 A/mm when the channel thickness increases to 2 nm. A raised source/drain structure with a thickness of 10 nm is employed, contributing to a low contact resistance of 0.15 Ωmm and a low contact resistivity of 1.1{\times}10-7 Ωcm2. The ITO transistor with a recessed channel and ferroelectric gating demonstrates several advantages over 2D semiconductor transistors and other thin film transistors, including large-area wafer-size nanometer thin film formation, low contact resistance and contact resistivity, atomic thin channel being immunity to short channel effects, large gate modulation of high carrier density by ferroelectric gating, high-quality gate dielectric and passivation formation, and a large bandgap for the low-power back-end-of-line (BEOL) CMOS application.

Some Common Mistakes in the Teaching and Textbooks of Modal Logic

description: We discuss four common mistakes in the teaching and textbooks of modal logic. The first one is missing the axiom $\Diamondφ\leftrightarrow\neg\Box\negφ$, when choosing $\Diamond$ as the primitive modal operator, misunderstanding that $\Box$ and $\Diamond$ are symmetric. The second one is forgetting to make the set of formulas for filtration closed under subformulas, when proving the finite model property through filtration, neglecting that $\Boxφ$ and $\Diamondφ$ may be abbreviations of formulas. The third one is giving wrong definitions of canonical relations in minimal canonical models that are unmatched with the primitive modal operators. The final one is misunderstanding the rule of necessitation, without knowing its distinction from the rule of modus ponens. To better understand the rule of necessitation, we summarize six ways of defining deductive consequence in modal logic: omitted definition, classical definition, ternary definition, reduced definition, bounded definition, and deflationary definition, and show that the last three definitions are equivalent to each other.

description: Motorcycle drivers are among the most vulnerable road users, accounting for a large proportion of global traffic accidents. This study aimed to investigate the association between the score of adult attention-deficit/hyperactivity (ADHD) traits and risky driving behaviors (RDB) with alcohol intake (AI) and narcotics consumption (NC) among motorcyclists in Iran. This multi-center cross-sectional study encompassed 1747 motorcyclists from three cities in Iran. A random sampling method was applied in this study, and the required data was collected using three standard questionnaires on ADHD, substance abuse, and RDB. Independent sample t-test, covariance analysis, and quantile regression (QR) were used to analyze the data. The results of t-test and analysis of covariance indicated that AI and NC were significantly associated with ADHD score and RDB among the motorcycle drivers. Additionally, the QR models showed that these effects were significant at all quantiles of ADHD and RDB, even for individuals who were at lower quantiles. Considering the potential dangers of driving after AI and NC, appropriate measures should be adopted before certifying a driving license to screen ADHD as a predisposing factor for substance abuse and RDB. Furthermore, it is essential to equip traffic police with adequate diagnosis kits and establish heavy penalties for the offenders. In this regard, all interventions aimed to reduce traffic accidents among motorcycle drivers should be done considering the interrelationship between ADHD, RDB, and substance abuse.

description: We compute the weight 2 cohomology of the Feynman transforms of the cyclic (co)operads $\mathsf{BV}$ and $\mathsf{HyCom}$, and the top$-2$ weight cohomology of the Feynman transforms of $D\mathsf{BV}$ and $\mathsf{Grav}$. Using a result of Giansiracusa, we compute, in particular, the top$-2$ weight cohomology of the handlebody group. We compare the result to the top$-2$ weight cohomology of the moduli space of curves $\mathcal{M}_{g,n}$, recently computed by Payne and the last-named author. We also provide another proof of a recent result of Hainaut-Petersen identifying the top weight cohomology of the handlebody group with the Kontsevich graph cohomology.

Infrared Abelian Dominance and Dual Higgs Mechanism in Maximally Abelian Gauge

description: We study infrared abelian dominance and the dual Higgs mechanism in the maximally abelian (MA) gauge using the lattice QCD Monte Carlo simulation. In the MA gauge, the off-diagonal gluon phase tends to be random, and the off-diagonal gluon $A_μ^\pm$ acquires the effective mass as $M_{\rm off} \simeq$ 1.2 GeV. From the monopole current in the MA gauge, we extract the dual gluon field $B_μ$ and estimate the dual gluon mass as $m_B \simeq $ 0.5 GeV. The QCD-monopole structure is also investigated in terms of off-diagonal gluons. From the lattice QCD in the MA gauge, the dual Ginzburg-Landau (DGL) theory can be constructed as a realistic infrared effective theory based on QCD.

description: Penrose's Spin Geometry Theorem is extended further, from $SU(2)$ and $E(3)$ (Euclidean) to $E(1,3)$ (Poincaré) invariant elementary quantum mechanical systems. The Lorentzian spatial distance between any two non-parallel timelike straight lines of Minkowski space, considered to be the centre-of-mass world lines of $E(1,3)$-invariant elementary classical mechanical systems with positive rest mass, is expressed in terms of \emph{$E(1,3)$-invariant basic observables}, viz. the 4-momentum and the angular momentum of the systems. An analogous expression for \emph{$E(1,3)$-invariant elementary quantum mechanical systems} in terms of the \emph{basic quantum observables} in an abstract, algebraic formulation of quantum mechanics is given, and it is shown that, in the classical limit, it reproduces the Lorentzian spatial distance between the timelike straight lines of Minkowski space with asymptotically vanishing uncertainty. Thus, the \emph{metric structure} of Minkowski space can be recovered from quantum mechanics in the classical limit using only the observables of abstract quantum mechanical systems.
