description: In real-world scenarios, person Re-IDentification (Re-ID) systems need to be adaptable to changes in space and time. Therefore, the adaptation of Re-ID models to new domains while preserving previously acquired knowledge is crucial, known as Lifelong person Re-IDentification (LReID). Advanced LReID methods rely on replaying exemplars from old domains and applying knowledge distillation in logits with old models. However, due to privacy concerns, retaining previous data is inappropriate. Additionally, the fine-grained and open-set characteristics of Re-ID limit the effectiveness of the distillation paradigm for accumulating knowledge. We argue that a Re-ID model trained on diverse and challenging pedestrian images at a large scale can acquire robust and general human semantic knowledge. These semantics can be readily utilized as shared knowledge for lifelong applications. In this paper, we identify the challenges and discrepancies associated with adapting a pre-trained model to each application domain and introduce the Distribution Aligned Semantics Adaption (DASA) framework. It efficiently adjusts Batch Normalization (BN) to mitigate interference from data distribution discrepancy and freezes the pre-trained convolutional layers to preserve shared knowledge. Additionally, we propose the lightweight Semantics Adaption (SA) module, which effectively adapts learned semantics to enhance pedestrian representations. Extensive experiments demonstrate the remarkable superiority of our proposed framework over advanced LReID methods, and it exhibits significantly reduced storage consumption. DASA presents a novel and cost-effective perspective on effectively adapting pre-trained models for LReID. The code is available at https://github.com/QizaoWang/DASA-LReID.

description: Data taken with positrons of different longitudinal polarisation states in collision with unpolarised protons at HERA are used to measure the total cross sections of the charged current process, e^+ p \to \barνX, for negative four-momentum transfer squared Q^2 > 400 GeV^2 and inelasticity y<0.9. Together with the corresponding cross section obtained from the previously published unpolarised data, the polarisation dependence of the charged current cross section is measured for the first time at high Q^2 and found to be in agreement with the Standard Model prediction.

description: In this paper, we present a new deep learning disruption prediction algorithm based on important findings from explorative data analysis which effectively allows knowledge transfer from existing devices to new ones, thereby predicting disruptions using very limited disruptive data from the new devices. The explorative data analysis conducted via unsupervised clustering techniques confirms that time-sequence data are much better separators of disruptive and non-disruptive behavior than the instantaneous plasma state data with further advantageous implications for a sequence-based predictor. Based on such important findings, we have designed a new algorithm for multi-machine disruption prediction that achieves high predictive accuracy on the C-Mod (AUC=0.801), DIII-D (AUC=0.947) and EAST (AUC=0.973) tokamaks with limited hyperparameter tuning. Through numerical experiments, we show that boosted accuracy (AUC=0.959) is achieved on EAST predictions by including in the training only 20 disruptive discharges, thousands of non-disruptive discharges from EAST, and combining this with more than a thousand discharges from DIII-D and C-Mod. The improvement of predictive ability obtained by combining disruptive data from other devices is found to be true for all permutations of the three devices. Furthermore, by comparing the predictive performance of each individual numerical experiment, we find that non-disruptive data are machine-specific while disruptive data from multiple devices contain device-independent knowledge that can be used to inform predictions for disruptions occurring on a new device.

The asymptotic boundary of these solutions are deSitter times a circle. By comparing boundary energies, we study the possibility of a transition from certain class of black holes to these bubbles below a critical radius of the boundary circle. We argue that this may occur when four parameters of the bubble satisfy a constraint among themselves.

description: The objective of this work was to estimate and to analyze the elasticity of substitution between Brazil, the USA and Argentina in the soybeans exports in the selected importers markets. This fact is important, considering that, it increases the integration of the world economies, placing in prominence of the adaptability to the world demand, as a fundamental factor for the exports expansion. Like this, given the economical relevance of the Brazilian exports of soybeans it was looked for, specifically, to verify the substitution possibility between the soybeans exports of Brazil, the USA and Argentina. After accomplishment of Dickey-Fuller expanded tests (ADF) for unit root, and Trace test and Max-eingevalue test for co-integration, the Error Correction Model (ECM) was adopted in the estimate of the elasticity of substitution. That model was shown well adjusted to the datas, allowing to identify the presence or absence of market rigidity, even so there is not perfect substitution in the soybeans exports. This way, investment in differentiation of the product, through rastreability and identity preservation can impulse the Brazilian exports.

description: We show that the largest disc covered by a simple random walk (SRW) on $\mathbb{Z}^2$ after n steps has radius n^{1/4+o(1)}, thus resolving an open problem of Révész [Random Walk in Random and Non-Random Environments (1990) World Scientific, Teaneck, NJ]. For any fixed $\ell$, the largest disc completely covered at least $\ell$ times by the SRW also has radius n^{1/4+o(1)}. However, the largest disc completely covered by each of $\ell$ independent simple random walks on $\mathbb{Z}^2$ after $n$ steps is only of radius $n^{1/(2+2\sqrt{\ell})+o(1)}$. We complement this by showing that the radius of the largest disc completely covered at least a fixed fraction $α$ of the maximum number of visits to any site during the first $n$ steps of the SRW on $\mathbb{Z}^2$, is $n^{(1-\sqrtα)/4+o(1)}$. We also show that almost surely, for infinitely many values of $n$ it takes about $n^{1/2+o(1)}$ steps after step n for the SRW to reach the first previously unvisited site (and the exponent 1/2 is sharp). This resolves a problem raised by Révész [Ann. Probab. 21 (1993) 318--328].

description: We propose a new strategy to search for a particular type of dark matter via nuclear capture. If the dark matter particle carries baryon number, as motivated by a class of theoretical explanations of the matter-antimatter asymmetry of the universe, it can mix with the neutron and be captured by an atomic nucleus. The resulting state de-excites by emitting a single photon or a cascade of photons with a total energy of up to several MeV. The exact value of this energy depends on the dark matter mass. We investigate the prospects for detecting dark matter capture signals in current and future neutrino and dark matter direct detection experiments.

Power consumption in pressure screens
Creators: name: Li, Yubing
Publisher: name: University of British Columbia
Year: 2009

description: Pressure screens are an important unit operation in the manufacture of high quality pulp and paper. During screening, a suspension of water, fibre and contaminants are separated based on their physical dimensions. Most of the research conducted previously focused on the fibre separation or contaminant separation performance, with few studies available in the field of power consumption. The objective of this dissertation is to investigate the factors that influence the power consumption in a pressure screen. This was accomplished by experimentally measuring the torque exerted on the rotor shaft in a laboratory Cross Sectional Screen for a wide range of design and operating conditions. The experimental results are presented in non-dimensional form and empirical correlations are derived. Two conditions were considered in this thesis: a rotor without elements on its periphery (a smooth rotor) and a rotor with elements. It was found that for smooth rotors, the spacing between the rotor and outer housing had a relatively small influence on the required torque (power). The fluid type and viscosity affected the flow behavior in different ways. "Drag reduction" was observed for pulp suspensions. The non-dimensional torque, scaled using viscosity, could be expressed as a power-law function of Reynolds number. The value of the exponent in our experiments was in the range of 1.32 to 1.68. For a rotor with elements, the additional torque generated by the elements was significantly influenced by the element height. This resulted from the high pressure drag on the leading edge of the elements and the vortices downstream. The torque coefficient based on the extra toque was independent of the Reynolds number, but was a strong function of the ratio of element height with rotor spacing.

description: This paper analyzes stochastic networks consisting of finite capacity nodes with different classes of requests which move according to some routing policy. The Markov processes describing these networks do not, in general, have reversibility properties, so the explicit expression of their invariant distribution is not known. Kelly's limiting regime is considered: the arrival rates of calls as well as the capacities of the nodes are proportional to a factor going to infinity. It is proved that, in limit, the associated rescaled Markov process converges to a deterministic dynamical system with a unique equilibrium point characterized by a nonstandard fixed point equation.

description: The objective of this paper was to analyze the risk protection provided by the futures contracts traded at CBOT (Chicago Board of Trade) at different delivery months to Brazilian Soybean hedgers. The empirical approach adopted was the estimation of hedging effectiveness between every Brazilian production state and the CBOT futures contracts. The results showed that the contracts for delivery in the second semester are more effective, mainly those for delivery in July and August. Moreover, supply shocks in the U.S. can make even the contracts for delivery in November and January to be very effective because of stronger procurement for Brazilian soybeans. The results also show that hedging effectiveness is larger near export harbors, as they were the cases of Cândido Mota (SP), Campo Mourão (PR) and Ponta Grossa (PR).

description: COVID-19 is a global epidemic. Till now, there is no remedy for this epidemic. However, isolation and social distancing are seemed to be effective preventive measures to control this pandemic. Therefore, in this paper, an optimization problem is formulated that accommodates both isolation and social distancing features of the individuals. To promote social distancing, we solve the formulated problem by applying a noncooperative game that can provide an incentive for maintaining social distancing to prevent the spread of COVID-19. Furthermore, the sustainability of the lockdown policy is interpreted with the help of our proposed game-theoretic incentive model for maintaining social distancing where there exists a Nash equilibrium. Finally, we perform an extensive numerical analysis that shows the effectiveness of the proposed approach in terms of achieving the desired social-distancing to prevent the outbreak of the COVID-19 in a noncooperative environment. Numerical results show that the individual incentive increases more than 85% with an increasing percentage of home isolation from 25% to 100% for all considered scenarios. The numerical results also demonstrate that in a particular percentage of home isolation, the individual incentive decreases with an increasing number of individuals.

description: Recent mm-wavelength surveys performed with the Atacama Large Millimeter Array (ALMA) have revealed protoplanetary discs characterized by rings and gaps. A possible explanation for the origin of such rings is the tidal interaction with an unseen planetary companion. The protoplanetary disc around DS Tau shows a wide gap in the ALMA observation at 1.3 mm. We construct a hydrodynamical model for the dust continuum observed by ALMA assuming the observed gap is carved by a planet between one and five Jupiter masses. We fit the shape of the radial intensity profile along the disc major axis varying the planet mass, the dust disc mass, and the evolution time of the system. The best fitting model is obtained for a planet with $M_{\rm p}=3.5\,M_{\rm Jup}$ and a disc with $M_{\rm dust}= 9.6\cdot10^{-5}\,M_{\odot}$. Starting from this result, we also compute the expected signature of the planet in the gas kinematics, as traced by CO emission. We find that such a signature (in the form of a "kink" in the channel maps) could be observed by ALMA with a velocity resolution between $0.2-0.5\,\rm{kms}^{-1}$ and a beam size between 30 and 50 mas.

description: The essays collected in this issue all stem from talks delivered at the International Conference, Aesthetic preferences, language games and forms of life: from Ludwig Wittgenstein, which was held on 23-25 January 2013 in the Aula Magna of the Faculty of Education at the University of Florence. Contributions are here published in the same order they were presented at the Conference. With fruitful variety of approach, the entire thematic spectrum of the relationship between Wittgenstein and aesthetics is covered: 1) the question of the presence of specific aesthetic issues in Wittgenstein’s works: from aesthetic judgment to the concept of the beautiful (J.-P. Cometti, G. Tomasi, G. Matteucci); 2) the question of the aesthetic paradigm as the key to understanding Wittgenstein’s philosophical research as a whole as well as the philosopher’s unmistakable style (F. Desideri, S. Säätelä, S. Borutti, F. Valagussa); 3) the issue concerning the crucial difference between showing and saying and the thin boundaries between sense and nonsense (V. Sanfélix, L. Distaso, M. De Iaco); 4) the peculiar, but extremely relevant, question concerning the relationship between music and language (J. Schulte, A. Arbo); 5) the question of the expressive character of the work of art and of the linguistic nature of poetry, considered as a vantage point for the pursuit of the analysis of linguistic facts, as well as the issue of the literary form of Wittgenstein’s later philosophy, with its deeply romantic character (M.W. Rowe, G. Di Giacomo); 6) the controversial issue of "seeing-as" and of its role within theories of depiction and pictoriality (K. Stock, A. Voltolini, E. Caldarola, E. Terrone).

description: The overlap, or similarity, between liquid configurations is at the core of the mean-field description of the glass transition, and remains a useful concept when studying three-dimensional glass-forming liquids. In liquids, however, the overlap involves a tolerance, typically of a fraction $a/σ$ of the inter-particle distance, associated with how precisely similar two configurations must be for belonging to the same physically relevant "state". Here, we systematically investigate the dependence of the overlap fluctuations and of the resulting phase diagram when the tolerance is varied over a large range. We show that while the location of the dynamical and thermodynamic glass transitions (if present) is independent of $a/σ$, that of the critical point associated with a transition between a low- and a high-overlap phases in the presence of an applied source nontrivially depends on the value of $a/σ$. We rationalize our findings by using liquid-state theory and the hypernetted chain (HNC) approximation for correlation functions. In addition, we confirm the theoretical trends by studying a three-dimensional glass-former by computer simulations. We show in particular that \rev{a range of $a/σ$ below what is commonly considered maximizes the temperature of the critical point, pushing it up in a liquid region where viscosity is low and computer investigations are easier due to a significantly faster equilibration.

description: AbstractDespite significant developments in the female labour market during the last century, comparisons between genders indicate the failure to reach equality in labour outcomes, identifying the gender pay gap as a crucial issue in political discussions and academia. This paper provides new empirical evidence on the gender wage gap and its determinants among UK graduates over the 1991-2021 period. Using UK household panel surveys, this study models wages against human capital and labour market characteristics to apply an Oaxaca-Blinder decomposition that divides the gap into explained and unexplained components. Results show that the unexplained gap increased from an insignificant gap in 1991 to 2011 and then declined. In 2021 the model explained 67.2% of the gap, mainly due to differences in work experience (31.1%), occupation (12.0%) and industry (23.3%). New research may analyse the causes of the rapid rise in occupational segregation and further expand the decomposition analysis to other countries.

Publisher: name: Zenodo
Year: 2024

description: This article contributes to the study of Moroccan teacher-researchers career trajectories. The contribution will allow not only for a better understanding, confirmation, examination, and discussion of the many causes for the university professor's career cap but also for a better contextualization of the current techniques employed to manage his career advancement.

Based on our findings, we present a fairly clear discussion of the assumptions, the career cap's most significant meaning for Moroccan academics in particular, its collective determinants (individual, organizational, and contextual), and its effects (both positive and negative) on their work behaviors and attitudes.

description: Superpositions of black holes can be described geometrically using a combined canonical formulation for space-time and quantum states. A previously introduced black-hole model that includes quantum fluctuations of metric components is shown here to give full access to the corresponding space-time geometry of weak-field gravity in terms of suitable line elements with quantum corrections. These results can be interpreted as providing covariant formulations of the gravitational force implied by a distribution of black holes in superposition. They can also be understood as a distribution of quantum matter constituents in superposition for a single black hole. A detailed analysis in the weak-field limit reveals quantum corrections to Newton's potential in generic semiclassical states, as well as new bounds on quantum fluctuations, implied by the covariance condition, rather than the usual uncertainty principle. These results provide additional control on quantum effects in Newton's potential that can be used in a broad range of predictions to be compared with observations.

A concise reference to (projected) Sersic R^{1/n} quantities, including Concentration, Profile Slopes, Petrosian indices, and Kron Magnitudes

description: Given the growing use of Sersic's (1963, 1968) R^{1/n} model for describing the stellar distributions in galaxies, and the lack of any single reference that provides the various associated mathematical expressions, we have endeavoured to compile such a resource here. We present the standard intensity profile, and its various guises such as the luminosity, surface-brightness, and aperture-magnitude profile. Expressions to transform the effective surface brightness into the mean effective and central surface brightness are also given, as is the expression to transform between effective radii and exponential scale-lengths. We additionally provide expressions for deriving the `concentration' of an R^{1/n} profile, and two useful equations for the logarithmic slope of the light-profile are given. Petrosian radii and fluxes are also derived for a range of Sersic profiles and compared with the effective radii and total flux. Similarly, expressions to obtain Kron radii and fluxes are presented as a function of the Sersic index n and the number of effective radii sampled. Illustrative figures are provided throughout. Finally, the core-Sersic model, consisting of an inner power-law and an outer-Sersic function, is presented.

Subleading Logarithmic QED Initial State Corrections to $e^+e^- \rightarrow γ^*/{Z^{0}}^*$ to $O(α^6 L^5)$

description: Using the method of massive operator matrix elements, we calculate the subleading QED initial state radiative corrections to the process $e^+e^- \rightarrow γ^*/Z^*$ for the first three logarithmic contributions from $O(α^3 L^3), O(α^3 L^2), O(α^3 L)$ to $O(α^5 L^5), O(α^5 L^4), O(α^5 L^3)$ and compare their effects to the leading contribution $O(α^6 L^6)$ and one more subleading term $O(α^6 L^5)$. The calculation is performed in the limit of large center of mass energies squared $s \gg m_e^2$. These terms supplement the known corrections to $O(α^2)$, which were completed recently. Given the high precision at future colliders operating at very large luminosity, these corrections are important for concise theoretical predictions. The present calculation needs the calculation of one more two--loop massive operator matrix element in QED. The radiators are obtained as solutions of the associated Callen--Symanzik equations in the massive case. The radiators can be expressed in terms of harmonic polylogarithms to weight {\sf w = 6} of argument $z$ and $(1-z)$ and in Mellin $N$ space by generalized harmonic sums. Numerical results are presented on the position of the $Z$ peak and corrections to the $Z$ width, $Γ_Z$. The corrections calculated result into a final theoretical accuracy for $δM_Z$ and $δΓ_Z$ which is estimated to be of O(30 keV) at an anticipated systematic accuracy at the FCC\_ee of \sim 100 keV. This precision cannot be reached, however, by including only the corrections up to $O(α^3)$.

description: A Cantor minimal system is of finite topological rank if it has a Bratteli-Vershik representation whose number of vertices per level is uniformly bounded. We prove that if the topological rank of a minimal dynamical system on a Cantor set is finite then all its minimal Cantor factors have finite topological rank as well. This gives an affirmative answer to a question posed by Donoso, Durand, Maass, and Petite.

description: Electrical energy storage is considered essential for the future energy systems. Among all the energy storage technologies, battery systems may provide flexibility to the power grid in a more distributed and decentralized way. In countries with deregulated electricity markets, grid-connected battery systems should be operated under the specific market design of the country. In this work, using the Spanish electricity market as an example, the barriers to grid-connected battery systems are investigated using utilization analysis. The concept of "potentially profitable utilization time" is proposed and introduced to identify and evaluate future potential grid applications for battery systems. The numerical and empirical analysis suggests that the high cycle cost for battery systems is still the main barrier for grid-connected battery systems. In Spain, for energy arbitrage within the day-ahead market, it is required that the battery wear cost decreases to 15 Euro/MWh to make the potentially profitable utilization rate higher than 20%. Nevertheless, the potentially profitable utilization of batteries is much higher in the applications when higher flexibility is demanded. The minimum required battery wear cost corresponding to 20% potentially profitable utilization time increases to 35 Euro/MWh for energy arbitrage within the day-ahead market and ancillary services, and 50 Euro/MWh for upward secondary reserve. The results of this study contribute to the awareness of battery storage technology and its flexibility in grid applications. The findings also have significant implications for policy makers and market operators interested in promoting grid-connected battery storage under a deregulated power market.
Majority Rule Dynamics in Finite Dimensions

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We investigate the long-time behavior of a majority rule opinion dynamics model in finite spatial dimensions. Each site of the system is endowed with a two-state spin variable that evolves by majority rule. In a single update event, a group of spins with a fixed (odd) size is specified and all members of the group adopt the local majority state. Repeated application of this update step leads to a coarsening mosaic of spin domains and ultimate consensus in a finite system. The approach to consensus is governed by two disparate time scales, with the longer time scale arising from realizations in which spins organize into coherent single-opinion bands. The consequences of this geometrical organization on the long-time kinetics are explored.

description: Multilegged robots have the ability to perform stable locomotion on relatively rough terrain. However, the complexity of legged robots over wheeled or tracked robots make them difficult to control. This paper presents OpenSHC (Open-source Syropod High-level Controller), a versatile high-level controller {capable of generating gaits and poses for quasi-static multilegged robots, both simulated and with real hardware implementations. With full Robot Operating System (ROS) integration, the controller can be quickly deployed on robots with different actuators and sensor payloads}. The flexibility of OpenSHC is demonstrated on the 30 degrees of freedom hexapod Bullet, analysing the energetic performance of various leg configurations, kinematic arrangements and gaits over different locomotion speeds. With OpenSHC being easily configured to different physical and locomotion specifications, a hardware-based parameter space search for optimal locomotion parameters is conducted. The experimental evaluation shows that the mammalian configuration offers lower power consumption across a range of step frequencies; with the insectoid configuration providing performance advantages at higher body velocities and increased stability at low step frequencies. OpenSHC is open-source and able to be configured for various number of joints and legs.

Lamb Shift of Unruh Detector Levels

description: We argue that the energy levels of an Unruh detector experience an effect similar to the Lamb shift in Quantum Electrodynamics. As a consequence, the spectrum of energy levels in a curved background is different from that in flat space. As examples, we consider a detector in an expanding Universe and in Rindler space, and for the latter case we suggest a new expression for the local virtual energy density seen by an accelerated observer. In the ultraviolet domain, that is when the space between the energy levels is larger than the Hubble rate or the acceleration of the detector, the Lamb shift quantitatively dominates over the thermal response rate.
