description: This article uses a partial equilibrium approach to measure the impact of trade liberalisation on the demand elasticity of labour in the apparel industry in Mauritius, a sector where, in general, those in the work force are poor. The findings reveal that there is no evidence that trade liberalisation has increased the overall labour demand elasticity with respect to wages, though it has increased the demand elasticity for female workers. We further examine the relationship between trade liberalisation measures and characteristics of poor households and find that the overall results are mixed and inconclusive, probably due to the high level of data aggregation.

description: We determine the \emph{$L_\infty$-algebra} that controls deformations of a relative Rota-Baxter Lie algebra and show that it is an extension of the dg Lie algebra controlling deformations of the underlying LieRep pair by the dg Lie algebra controlling deformations of the relative Rota-Baxter operator. Consequently, we define the {\em cohomology} of relative Rota-Baxter Lie algebras and relate it to their infinitesimal deformations. A large class of relative Rota-Baxter Lie algebras is obtained from triangular Lie bialgebras and we construct a map between the corresponding deformation complexes. Next, the notion of a \emph{homotopy} relative Rota-Baxter Lie algebra is introduced. We show that a class of homotopy relative Rota-Baxter Lie algebras is intimately related to \emph{pre-Lie$_\infty$-algebras}.

Flow of temporal network properties under local aggregation and time shuffling: a tool for characterizing, comparing and classifying temporal networks

description: Although many tools have been developed and employed to characterize temporal networks, the issue of how to compare them remains largely open. It depends indeed on what features are considered as relevant, and on the way the differences in these features are quantified. In this paper, we propose to characterize temporal networks through their behaviour under general transformations that are local in time: (i) a local time shuffling, which destroys correlations at time scales smaller than a given scale $b$, while preserving large time scales, and (ii) a local temporal aggregation on time windows of length $n$. By varying $b$ and $n$, we obtain a flow of temporal networks, and flows of observable values, which encode the phenomenology of the temporal network on multiple time scales. We use a symbolic approach to summarize these flows into labels (strings of characters) describing their trends. These labels can then be used to compare temporal networks, validate models, or identify groups of networks with similar labels. Our procedure can be applied to any temporal network and with an arbitrary set of observables, and we illustrate it on an ensemble of data sets describing face-to-face interactions in various contexts, including both empirical and synthetic data.

description: We investigate the concurrence and Bell violation of the standard Werner state or Werner-like states in the presence of collective dephasing. It is shown that the standard Werner state and certain kinds of Werner-like states are robust against the collective dephasing, and some kinds of Werner-like states is fragile and becomes completely disentangled in a finite-time. The threshold time of complete disentanglement of the fragile Werner-like states is given. The influence of external driving field on the finite-time disentanglement of the standard Werner state or Werner-like states is discussed. Furthermore, we present a simple method to control the stationary state entanglement and Bell violation of two qubits. Finally, we show that the theoretical calculations of fidelity based on the initial Werner state assumption well agree with previous experimental results.

Non-reciprocity is necessary for robust dimensional reduction and strong responses in stochastic topological systems

description: Topological theory predicts the necessary conditions for robust dimensional reduction in a host of quantum and classical systems. Models have recently been proposed for stochastic systems which describe many biological and chemical phenomena. However, general theoretical principles are lacking for this class of systems, exemplified by the breakdown of the celebrated bulk-edge correspondence. We prove that contrary to topological phases in quantum and many classical systems, stochastic systems require non-reciprocal (or non-Hermitian) transitions for robust edge responses, which holds across all dimensions and geometries. We propose a novel explanation of hybridization that destroys edge responses in reciprocal (Hermitian) stochastic systems. Further, we show that stochastic steady states grow dramatically with non-reciprocity, in contrast to their quantum counterparts which plateaus. We analyze the resulting theoretical and physical consequences and how non-reciprocity mitigates the effects of hybridization towards robust edge states in equilibrium and non-equilibrium steady states. These results establish the crucial role of non-reciprocal interactions for responses that are robust to random perturbations in active and living matter.

description: The rapid spread of COVID-19 has made manual contact tracing difficult. Thus, various public health authorities have experimented with automatic contact tracing using mobile applications (or "apps"). These apps, however, have raised security and privacy concerns. In this paper, we propose an automated security and privacy assessment tool, COVIDGUARDIAN, which combines identification and analysis of Personal Identification Information (PII), static program analysis and data flow analysis, to determine security and privacy weaknesses. Furthermore, in light of our findings, we undertake a user study to investigate concerns regarding contact tracing apps. We hope that COVIDGUARDIAN, and the issues raised through responsible disclosure to vendors, can contribute to the safe deployment of mobile contact tracing. As part of this, we offer concrete guidelines, and highlight gaps between user requirements and app performance.

description: We show that the spatio-temporal ElectroHydroDynamic (EHD) force production in surface AC-Dielectric Barrier Discharge (AC-DBD) actuators is strongly influenced by both the streamer regime during the positive phase and the micro-discharge regime during the negative phase. Focusing on the spatial EHD force profiles, we demonstrate that the ionic wind spatial distribution can only be explained by the positive contribution of the streamer regime. The location of maximum ionic wind is found to be directly linked with the maximum elongation of the streamers at several millimeters from the exposed electrode. In both positive and negative phases of the AC-DBD operation, residual volumetric and surface charges once again linked to the streamer formation and afterburn, result to a variety of positive EHD force zones which, when time-averaged in one AC period, contribute to the generation of the experimentally observed induced thin wall jet. Through a thorough elaboration of our numerical results, we provide an illustrative explanation of the EHD force spatio-temporal evolution, showcase the importance of streamers and retrieve a correct representation of the ionic wind spatial profiles when compared to experiments.

Brane world unification of quark and lepton masses and its implication for the masses of the neutrinos

Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: A TeV-scale scenario is constructed in an attempt to understand the relationship between quark and lepton masses. This scenario combines a model of early (TeV) unification of quarks and leptons with the physics of large extra dimensions. It demonstrates a relationship between quark and lepton mass scales at rather ``low'' (TeV) energies which will be dubbed as {\em early quark-lepton mass unification}. It also predicts that the masses of the neutrinos are naturally light and Dirac. There is an interesting correlation between neutrino masses and those of the unconventionally charged fermions which are present in the early unification model. If these unconventional fermions were to lie between 200 GeV and 300 GeV, the Dirac neutrino mass scale is predicted to be between 0.07 eV and 1 eV.

Parametrized multipolar gravitational waveforms for testing general relativity: Amplitude corrections up to 2PN order

Publisher: name: arXiv
Year: 2023
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: A parametrized multipolar gravitational wave phasing within multipolar post-Minkowskian and post-Newtonian formalism was developed in earlier works [S. Kastha et al., PRD 98, 124033 (2018) and PRD 100, 044007 (2019)]. This facilitates the model-agnostic tests for the multipolar structure of compact binaries using gravitational wave observations. In this paper, we derive a parametrized multipolar amplitude of the gravitational wave signal in terms of mass and current-type radiative multipole moments within the post-Newtonian approximation to general relativity. We assume the compact binary to be moving in quasicircular orbits, with component spins (anti-) aligned with respect to the binary's orbital angular momentum. We report a closed-form expression for the parametrized multipolar amplitude of the waveform at second post-Newtonian order both in time and frequency domains. This includes the contribution from the leading five mass-type and the leading four current-type radiative moments. This framework of constructing a parametrized waveform accomplishes a generic parametrization of both gravitational wave phase and amplitude with the same set of phenomenological parameters. Hence, it should significantly enhance the precision of the multipole tests in the context of present and future gravitational wave detectors.

description: The instability of the producers and investors income coming from price fluctuation is a problem whose characteristics and causes should be thoroughly investigated given the importance of the commodity in the national agribusiness and their losses in terms of profitability, jobs and exchange value to Brazil. Given that, it is used the class of autoregressive conditional heteroscedasticity models (ARCH and GARCH) to characterize and analyze the volatility of the time series of monthly returns of soy, coffee, corn and fat ox. This analysis shows that these products are marked by having high price fluctuations, in which positive or negative shocks generate impacts in the long run. The sum of the volatility reaction and persistence coefficients showed values close or larger than one, indicating that the shocks up on volatility will last for a long period of time.

description: Using an isospin- and momentum-dependent transport model we study near-threshold pion production in heavy-ion collisions induced by radioactive beams at the planned Rare Isotope Accelerator (RIA). We revisit the question of probing the high density behavior of nuclear symmetry energy $E_{sym}(ρ)$ using the $π^-/π^+$ ratio. It is found that both the total and differential $π^-/π^+$ ratios remain sensitive to the $E_{sym}(ρ)$ when the momentum-dependence of both the isoscalar and isovector potentials are consistently taken into account. Moreover, the multiplicity and spectrum of $π^-$ mesons are found more sensitive to the $E_{sym}(ρ)$ than those of $π^+$ mesons. Finally, effects of the Coulomb potential on the pion spectra and $π^-/π^+$ ratio are also discussed.

description: Today's mechanical sensors are capable of detecting extremely weak perturbations while operating near the standard quantum limit. However, further improvements can be made in both sensitivity and bandwidth when we reduce the noise originating from the process of measurement itself -- the quantum-mechanical backaction of measurement -- and go below this 'standard' limit, possibly approaching the Heisenberg limit. One of the ways to eliminate this noise is by measuring a quantum nondemolition variable such as the momentum in a free-particle system. Here, we propose and characterize theoretical models for direct velocity measurement that utilize traditional electric and magnetic transducer designs to generate a signal while enabling this backaction evasion. We consider the general readout of this signal via electric or magnetic field sensing by creating toy models analogous to the standard optomechanical position-sensing problem, thereby facilitating the assessment of measurement-added noise. Using simple models that characterize a wide range of transducers, we find that the choice of readout scheme -- voltage or current -- for each mechanical detector configuration implies access to either the position or velocity of the mechanical sub-system. This in turn suggests a path forward for key fundamental physics experiments such as the direct detection of dark matter particles.

description: The study of the spatial distribution of the production of coffee between the 558 micro Brazilian regions is the main aim of this paper. The research is for the period 1991 to 2003. This paper enables us to identify spatial regimes and clusters for coffee’s production and also it’s dynamic during the period. To reach the objective we use the idea of locational quotient to measure the concentration in the production of coffee and also the exploratory spatial data analysis. It was possible to verify that the spatial structure of production of coffee remains spatially concentrated, mainly at Minas Gerais and Espirito Santo states. Those states represent 70.66% of total production of coffee. The result for some micro regions located at Rondonia is also important.

description: Time domain deBroglie wave interferometry [Cahn et al, Phys. Rev. Lett. 79, 784] is applied to Rb87 atoms in a magnetic guide. A standing wave light field is carefully aligned along the guiding direction of the magnetic trapping potential from a soft-ferromagnetic 4-foil structure. A sequence of two standing wave pulses is applied to the magnetically trapped atoms. The backscattered light at the atomic density grating revival time is collected and detected via a heterodyning technique. In addition to the observed recoil oscillations that fit the interferometer theory for atoms in free space, we observe a decay of the interferometer contrast on a millisecond time scale with unexpected millisecond-scale oscillations. We find that the oscillating decay is explained by a residual variation of the linear trapping potential along the standing wave direction.

description: Note: This talk has not gone through a process of peer review, and findings should therefore be treated as preliminary and subject to change. SOAS Linguistics Webinars: Gender Representation in Constructed Example Sentences
 March 24, 2021 Hadas Kotek (MIT) Abstract: This talk surveys two ongoing projects concerned with the representation of women in example sentences in linguistics. (Collaborations with Paola Cépeda, Katharina Pabst, Kristen Syrett, Sarah Babinski, Rikker Dockum, and Christopher Geissler.) The first half of the talk focuses on constructed example sentences in syntax textbooks. Following the 20th anniversary of Macaulay & Brice (1997: M&B)’s survey of example sentences in 11 syntax textbooks, we present an analysis of 6 recently published textbooks. We find that the gender skew and stereotypes reported in M&B are almost all still present: Among other findings, men are twice as likely to occur as subjects, agents, and experiencers. Men additionally engage in intellectual activities, have diverse occupations, and engage in violent activities. The second project examines example sentences published in all papers published in Language, Linguistic Inquiry, and Natural Language & Linguistic Theory over the past 20 years. We find striking similarities to prior work, but are able to provide greater detail. Among our findings: men are more than twice as likely to occur as subjects, agents, and experiencers; men engage in violence and exhibit negative emotion while women are referred to using kinship terms and express positive emotion. These trends remain stable over time and across journals, and do not vary by the language of example. I conclude the talk by discussing the importance of raising awareness of biases in research and teaching materials among individual researchers and (especially) instructors, as well as how we can improve on the current standards.

description: The objective of this study is to determine the optimum economically location of new slaughter and processing plants of poultry and pork in Brazil, considering the minimization of transportation cost and acquisition of corn and soy bran, and the transportation cost of meat. The theory of localization was used, as theoretical approach, reletead to the weberiana theory of the industrial localization, used, with larger intensity. Network capacited model is used as analytic tool. The main result was the indication of Cândido Mota, SP, for the set the processing plant, due, mainly, a short distance among that municipal district and the corn production cluster and its proximity with important meat consuming areas, and with the main ports. The results indicated: for two plants, Cristalina, GO, and Mafra, SC; for the three plants, the two cities previously mentioned, with the inclusion of Cândido Mota, SP, and for four plants, it is insert Lucas do Rio Verde, MT. It was observed that the minimum medium cost of attendance of meat demand, considering the brazilian internal consumption and the exports, was resultant of to opening of four plants that cost decrease was due to reduction in the distance traveled by the until the consuming markets.

description: Assuming that the effect of the residual interaction beyond mean-field is weak and has a short memory time, two approximate treatments of correlation in fermionic systems by means of Markovian quantum jump are presented. A simplified scenario for the introduction of fluctuations beyond mean-field is first presented. In this theory, part of the quantum correlations between the residual interaction and the one-body density matrix are neglected and jumps occur between many-body densities formed of pairs of states $D=| Φ_a > < Φ_b |/< Φ_b . |Φ_a >$ where $| Φ_a >$ and $| Φ_b >$ are antisymmetrized products of single-particle states. The underlying Stochastic Mean-Field (SMF) theory is discussed and applied to the monopole vibration of a spherical $^{40}$Ca nucleus under the influence of a statistical ensemble of two-body contact interaction. This framework is however too simplistic to account for both fluctuation and dissipation. In the second part of this work, an alternative quantum jump method is obtained without making the approximation on quantum correlations. Restricting to two particles-two holes residual interaction, the evolution of the one-body density matrix of a correlated system is transformed into a Lindblad equation. The associated dissipative dynamics can be simulated by quantum jumps between densities written as $D = | Φ>< Φ|$ where $| Φ>$ is a normalized Slater determinant. The associated stochastic Schroedinger equation for single-particle wave-functions is given.

description: This research analyzed the integrated and independent systems of pork production in Brazil, using multiple case studies, which focused on confined and complete-cycle producing units of swines, in the high and low profits periods of the activity. The study focused on the pork production of the State of Santa Catarina (SC), Brazilian’s greatest producer of swines, and presenting the predominance of integrated production, and on the Vale do Piranga (MG) region, one of the main Brazilian regions of the independent production system. The work analyzed the yield of the two systems of pork production through the analysis of the performance of each system in different scenarios. The costs and incomes (economic efficiency) of six producing pork farms, in which three belonged to one production system and three to the other, was the basic analytical structure of the study. The Monte Carlo method was used to analyze the performance of each farm. Considering the comparison between the two production systems in different time periods, in prosperity time, the independent pork production farms presented higher returns. On the other hand, in period of crisis, the integrated production system farms were more successful in terms of performance, as the independent ones presented higher losses.

description: Emerging infectious diseases are existential threats to human health and global stability. The recent outbreaks of the novel coronavirus COVID-19 have rapidly formed a global pandemic, causing hundreds of thousands of infections and huge economic loss. The WHO declares that more precise measures to track, detect and isolate infected people are among the most effective means to quickly contain the outbreak. Based on trajectory provided by the big data and the mean field theory, we establish an aggregated risk mean field that contains information of all risk-spreading particles by proposing a spatio-temporal model named HiRES risk map. It has dynamic fine spatial resolution and high computation efficiency enabling fast update. We then propose an objective individual epidemic risk scoring model named HiRES-p based on HiRES risk maps, and use it to develop statistical inference and machine learning methods for detecting suspected epidemic-infected individuals. We conduct numerical experiments by applying the proposed methods to study the early outbreak of COVID-19 in China. Results show that the HiRES risk map has strong ability in capturing global trend and local variability of the epidemic risk, thus can be applied to monitor epidemic risk at country, province, city and community levels, as well as at specific high-risk locations such as hospital and station. HiRES-p score seems to be an effective measurement of personal epidemic risk. The accuracy of both detecting methods are above 90\% when the population infection rate is under 20\%, which indicates great application potential in epidemic risk prevention and control practice.

description: We introduce a simple autoencoder based on hyperbolic geometry for solving standard collaborative filtering problem. In contrast to many modern deep learning techniques, we build our solution using only a single hidden layer. Remarkably, even with such a minimalistic approach, we not only outperform the Euclidean counterpart but also achieve a competitive performance with respect to the current state-of-the-art. We additionally explore the effects of space curvature on the quality of hyperbolic models and propose an efficient data-driven method for estimating its optimal value.

Search for light long-lived neutral particles from Higgs boson decays via vector-boson-fusion production from $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

description: A search is reported for long-lived dark photons with masses between 0.1 GeV and 15 GeV, from exotic decays of Higgs bosons produced via vector-boson-fusion. Events that contain displaced collimated Standard Model fermions reconstructed in the calorimeter or muon spectrometer are probed. This search uses the full LHC Run 2 (2015-2018) data sample collected in proton-proton collisions at $\sqrt{s}=13$ TeV, corresponding to an integrated luminosity of 139 $fb^{-1}$. Dominant backgrounds from Standard Model processes and non-collision sources are estimated by using data-driven techniques. The observed event yields in the signal regions are consistent with the expected background. Upper limits on the Higgs boson to dark photon branching fraction are reported as a function of the dark-photon mean proper decay length or of the dark-photon mass and the coupling between the Standard Model and the potential dark sector. This search is combined with previous ATLAS searches obtained in the gluon-gluon fusion and \textit{WH} production modes. A branching fraction above 10\% is excluded at 95\% CL for a 125 GeV Higgs boson decaying into two dark photons for dark-photon mean proper decay lengths between 173 and 1296 mm and mass of 10 GeV.

description: The present development in the Brazilian Agro-business, which regards this country as one the most competitive nations in terms of agro industrial commodities, had its best expansion moments from 2006 on especially with the fall of Real currency and due to an increasingly demand in the international market. The aim of this article is to analyze the specialization and competitiveness of the agro-industry in the state of Minas Gerais and its contribution to the increase in the Brazilian exportations. To that end, indexes based on commercial flux will be used so that we are able to identify the trends in the international marked in terms of specializations. The analyses of the international business structure and the profitable competitiveness have shown the diversity of Minas Gerais agro-business, started off in 1999, with the increase in the so-called ‘strong spots’ of economy. Not only did Minas Gerais State manage to keep the competitiveness in traditional sectors such as coffee and timber industry but it also diversified its production to other potential sectors of its economy. However, the competitiveness index has come as ‘neutral’ due to low competition, a fact that has been gradually overcome. Should such tendency maintain, without a shadow of doubt, the agro-business will soon be considered as a strong spot in the Mineira economy.

description: Adding or subtracting a single quantum of excitation to a thermal state of a bosonic system has the counter-intuitive effect of approximately doubling its mean occupation. We perform the first experimental demonstration of this effect outside optics by implementing single-phonon addition and subtraction to a thermal state of a mechanical oscillator via Brillouin optomechanics in an optical whispering-gallery microresonator. Using a detection scheme that combines single-photon counting and optical heterodyne detection, we observe this doubling of the mechanical thermal fluctuations to a high precision. The capabilities of this joint click-dyne detection scheme adds a significant new dimension for optomechanical quantum science and applications.

description: We determine diameters of Markov chains describing one-dimensional N -particle models with an exclusion interaction, namely the Ssep (symmetric simple exclusion process) and one of its non-reversible liftings, the lifted Tasep (totally asymmetric simple exclusion process). The diameters provide lower bounds for the mixing times, and we discuss the implications of our findings for the analysis of these models.
Performance evaluation and optimization of MPEG-4 video streaming over CDMA wireless networks

description: With the advent of next-generation multimedia technologies such as the low bit rate MPEG-4 codec, multimedia streaming over third generation (3G) wireless networks becomes a reality. To deal with the error prone and bandwidth limited nature of wireless networks, this thesis presents a novel error control scheme called Adaptive Delay-constrained Selective Repeat ARQ (ADSR-ARQ) in the radio link layer. ADSR-ARQ is capable of dynamically switching between ARQ and non-ARQ mode and adjusts the retransmission attempts based on the predefined transmission buffer length thresholds to satisfy the overall quality of service (QoS) requirements of video streams. An analytical model is created to analyze the feasibility and efficiency of this measurement-based ARQ scheme. To evaluate the performance of the proposed ADSR-ARQ error control scheme under wireless multimedia environment, as well as to investigate the behavior of video streaming applications under various wireless network conditions, we build a LAN-based real-time wireless video streaming testbed. This testbed includes a wireless emulator, an MPEG-4 streaming server and a client. The wireless emulator implementation is based on the NS2 simulation platform operating in emulation mode to simulate the behavior of CDMA wireless networks, such as packet loss and delay, etc. A two-state Markov chain channel model is implemented in the wireless emulator to model the burst error behavior in wireless networks. In this thesis, end-to-end delay/jitter and throughput of MPEG-4 video transmission are measured under different error conditions over the testbed. The tradeoff between packet loss and delay is evaluated. From the theoretical analysis and experiments results, with an optimal design, our proposed innovative ADSR-ARQ error control scheme can effectively decrease packet losses and improve the channel utilization significantly under specified delay constraints. The ADSR-ARQ scheme outperforms the conventional SR-ARQ scheme with throughput improvement and delay decrease for transmitting MPEG-4 video stream over wireless networks. We also employ a pseudo Robust Header Compression (ROHC) function to demonstrate how the header compression scheme improves the wireless bandwidth efficiency. Furthermore, for future streaming media applications, this wireless emulator is an invaluable tool for the development and verification of new algorithms over wireless networks.
