description: Background: Due to the deficit of knowledge on fine motor skill far transfer from one domain of expertise to another, piano performance and surgical training serve as a relevant, interdisciplinary context in which to study the transfer of motor skills given both have relatively well-established levels of performance and require complex fine motor skills. Musicians tend to demonstrate greater ease in all aspects of procedural knowledge which are known to contribute to the early stages of motor learning. Previous research in the Piano Pedagogy Research Laboratory (PPRL) found that extensive piano training was correlated with faster learning of surgical knot-tying skills. However, the short-term two-day timeline was a limitation of the study. Objective: Our project has built on previous work in the PPRL to address the short-term nature of previous studies by measuring a long-term performance curve as well as retention of surgical training and also expanded on the previous project by focussing this time on laparoscopic tasks. This study compared performance curves of two participant groups (pianists and controls) over five consecutive days and retention one week later, as measured by speed and accuracy of task completion. Laparoscopic training consisted of six tasks repeated at every session. Since laparoscopy involves a variety of abilities concurrently, we also administered a battery of ten psychometric tests to isolate and measure specific aspects of non-motor and fine motor skills. Results: There was no statistical difference between participant groups on the majority of laparoscopic training and psychomotor assessments based on two-way mixed ANOVA and Mann-Whitney U test analysis, respectively. There were also little to no significant correlations between abilities and laparoscopic performance. The only significant confounding variable was that the control group was significantly more interested in surgery than the musician group (p = .037). Conclusion: Overall, these results demonstrate that piano performance training did not far transfer to laparoscopic surgery. This is relevant to the debate on far transfer of motor skills given this study’s robust design which addressed previous shortcomings by including a longer timeline and more specifications of musicians’ characteristics. Our findings indicate that fine motor skills are domain specific to music and surgery, respectively.

description: Automated feature engineering (AutoFE) is the process of automatically building and selecting new features that help improve downstream predictive performance. While traditional feature engineering requires significant domain expertise and time-consuming iterative testing, AutoFE strives to make feature engineering easy and accessible to all data science practitioners. We introduce a new AutoFE algorithm, IIFE, based on determining which feature pairs synergize well through an information-theoretic perspective called interaction information. We demonstrate the superior performance of IIFE over existing algorithms. We also show how interaction information can be used to improve existing AutoFE algorithms. Finally, we highlight several critical experimental setup issues in the existing AutoFE literature and their effects on performance.

description: The transition metal dichalcogenide PdTe$_2$ was recently shown to be a unique system where a type II Dirac semimetallic phase and a superconducting phase co-exist. This observation has led to wide speculation on the possibility of the emergence of an unconventional topological superconducting phase in PdTe$_2$. Here, through direct measurement of the superconducting energy gap by scanning tunneling spectroscopy (STS), and temperature and magnetic field evolution of the same, we show that the superconducting phase in PdTe$_2$ is conventional in nature. The superconducting energy gap is measured to be 326 $μ$eV at 0.38 K and it follows a temperature dependence that is well described within the framework of Bardeen-Cooper-Schriefer's (BCS) theory of conventional superconductivity. This is surprising because our quantum oscillation measurements confirm that at least one of the bands participating in transport has topologically non-trivial character.

description: The use of abstraction in problem solving is an effective approach to reducing search, but finding good abstractions is a difficult problem. The first algorithm that completely automates the generation of abstraction hierarchies is Knoblock's ALPINE, but this algorithm is only able to automatically abstract the preconditions of operators. In this pa- per we present an algorithm that automatically abstracts not only the preconditions but also the effects of operators, and produces finer-grained abstraction hierarchies than ALPINE. The same algorithm also formalizes and selects the primary effects of operators, which is thus useful even for planning without abstraction. We present a theorem that describes the necessary and sufficient conditions for a planner to be complete, when guided by primary effects.
Is Monetary Policy More Powerful in Recessions or Expansions? Evidence from Canada
Creators: name: Trujillo, Jaime
Publisher: name: My University
Year: 2018

description: Using the local projection strategy of Jordà (2005) along the smooth transition regression of Granger and Teräsvirta (1993), this paper investigates whether the impact of monetary policy varies according to the state of the business cycle. To estimate the model, the paper uses a novel Canadian monetary policy shock series identified by Champagne and Sekkel (2017) and a “state variable” that captures the state of the business cycle. The paper finds that monetary policy tends to be more powerful in expansions than in recessions, particularly due to a higher sensitivity of business and housing investment and durable consumption to changes in the policy rate. While prices appear to be fairly “sticky” in expansions following a contractionary shock, the opposite is true in recessions when prices respond more vividly. The differences observed across expansionary and contractionary regimes emerge whether the “state variable” used in the empirical estimation captures the growth rate of economic activity (i.e. growth rate of GDP) or the level of resource utilization (i.e. output gap).

description: A quantitative evaluation of dilepton sources in heavy-ion reactions is performed taking into account both thermal and non-thermal production mechanisms. The hadronic thermal emission rate is based on an electromagnetic current-correlation function with a low-mass region (LMR, M \lsim 1 GeV) dominated by vector mesons (ρ, ω, ϕ) and an intermediate-mass region (IMR, 1 GeV \le M \le 3 GeV) characterized by (the onset of) a multi-meson continuum. A convolution of the emission rates over a thermal fireball expansion results in good agreement with experiment in the low-mass spectra, confirming the predicted broadening of the ρmeson in hadronic matter in connection with the prevalence of baryon-induced medium effects. The absolute magnitude of the LMR excess is mostly controlled by the fireball lifetime, which in turn leads to a consistent explanation of the dilepton excess in the IMR in terms of thermal radiation. The analysis of experimental transverse-momentum (q_T) spectra reveals discrepancies with thermal emission for q_T \gsim 1 GeV in noncentral In-In collisions, which we address by extending our calculations by: (i) a refined treatment of ρdecays at thermal freezeout, (ii) primordially produced ρ's subject to energy-loss, (iii) Drell-Yan annihilation, and (iv) thermal radiation from t-channel meson exchange processes. We investigate the sensitivity of dilepton spectra to the critical temperature and hadro-chemical freezeout of the fireball. The ρbroadening in the LMR turns out to be robust, while in the IMR Quark-Gluon Plasma radiation is moderate unless the critical temperature is rather low.

description: Hac1p is a key transcription factor regulating the unfolded protein response (UPR) induced by abnormal accumulation of unfolded/misfolded proteins in the endoplasmic reticulum (ER) in Saccharomyces cerevisiae. The accumulation of unfolded/misfolded proteins is sensed by protein Ire1p, which then undergoes trans-autophosphorylation and oligomerization into discrete foci on the ER membrane. HAC1 pre-mRNA, which is exported to the cytoplasm but is blocked from translation by its intron sequence looping back to its 5'UTR to form base-pair interaction, is transported to the Ire1p foci to be spliced, guided by a cis-acting bipartite element at its 3'UTR (3'BE). Spliced HAC1 mRNA can be efficiently translated. The resulting Hac1p enters the nucleus and activates, together with coactivators, a large number of genes encoding proteins such as protein chaperones to restore and maintain ER homeostasis and secretary protein quality control. This review details the translation regulation of Hac1p production, mediated by the nonconventional splicing, in the broad context of translation control and summarizes the evolution and diversification of the UPR signaling pathway among fungal, metazoan and plant lineages.

description: We argue that when the number of spins $N$ in the SK model is finite, the Parisi scheme can be terminated after $K$ replica-symmetry breaking steps, where $K(N) \propto N^{1/6}$. We have checked this idea by Monte Carlo simulations: we expect the typical number of peaks and features $R$ in the (non-bond averaged) Parisi overlap function $P_J(q)$ to be of order $2K(N)$, and our counting (for samples of size $N$ up to 4096 spins) gives results which are consistent with our arguments. We can estimate the leading finite size correction for any thermodynamic quantity by finding its $K$ dependence in the Parisi scheme and then replacing $K$ by K(N). Our predictions of how the Edwards-Anderson order parameter and the internal energy of the system approach their thermodynamic limit compare well with the results of our Monte Carlo simulations. The $N$-dependence of the sample-to-sample fluctuations of thermodynamic quantities can also be obtained; the total internal energy should have sample-to-sample fluctuations of order $N^{1/6}$, which is again consistent with the results of our numerical simulations.

description: Clarke et al. (1986) have developed a model-based verification method and have applied it to validation of VLSI circuits. We have used the method to test automatically the safety and operability of discrete chemical process control systems. The technique involves: (1) a system model describing the process and its software; (2) assertions in temporal logic expressing user-supplied questions about the system behavior with respect to safety and operability; and (3) a model checker that determines if the system model satisfies each of the assertions and provides a counterexample to locate the error if one exists. Temporal logic is used for reasoning about occurrence of events over time. To reveal discrete event errors, we have applied the verification method to a simple combustion system and an alarm acknowledge system.
Minimum Wages and Employment during COVID-19: The Case of Canada

description: COVID-19 is a contagious respiratory disease that first emerged in December 2019 and spread around the world within months. The infectious virus has created numerous health, social, and economic challenges worldwide, among others. On March 11, 2020 the World Health Organization (WHO, 2020) announced COVID-19 as a global health crisis, while declaring the disease as a pandemic. 1 The disease has created an unprecedented global economic recession: The World Bank (2020) projects a 5.2 percent contraction in global GDP in 2020, the deepest global recession in decades. In Canada, the first case of COVID-19 appeared in January 2020. By the end of August 2020, there were approximately 129,000 active cases in Canada. Figure 1 shows a timeline of the outbreak in Canada from January 2019 to August 2020. Starting in March 2020, most Canadian provinces had imposed restrictions on companies, which included the closing non-essential businesses. While necessary, these measurements have placed economic constraints that led the country into a recession. In addition, unemployment rates have been soaring around the world, and Canada is no exception. The federal and provincial governments have put in place different economic response plans to support businesses and individuals, such as the Employment Insurance and the Canada Emergency Response Benefit (CERB). Along with this policies, provincial governments have maintained yearly increases in the minimum wage. Figure 3 shows the minimum wage across those provinces that increased it throughout the pandemic.

description: Primordial Black Holes (PBHs) are capable of emitting extremely energetic particles independent of their interactions with the Standard Model. In this work, we investigate whether PBHs evaporating in the early universe could be responsible for some of the observed high-energy neutrinos above the TeV or PeV scale in the present universe. We compute the energy spectrum of neutrinos directly emitted by PBHs with a monochromatic mass function and estimate the wash-out point, which determines the maximum energy of the spectrum. We find that the spectrum generally extends to high energies following a power law of $E_ν^{-3}$ until it reaches the wash-out point, which crucially depends on the PBH mass. For PBHs of $10^{13}$ grams, the spectrum can extend up to the PeV scale, though the flux is too low for detection. We also consider an indirect production mechanism involving dark particles that are emitted by PBHs and decay into neutrinos at a much later epoch. This mechanism allows lighter (such as those in the gram to kilogram range) PBHs to produce more energetic neutrino fluxes without being washed out by the thermal plasma in the early universe. In this scenario, we find that ultra-high-energy neutrinos around or above the EeV scale can be generated, with sufficiently high fluxes detectable by current and future high-energy neutrino observatories such as IceCube and GRAND.

description: The neutron lifetime, $τ$ = 880.2 $\pm$ 1.0 sec , is an important parameter for particle physics and cosmology. There is, however, an 8.4 sec (4.0$\,σ$) deviation between the measured value of the neutron lifetime using two methods : one method counts neutrons that survive after some time, while the other counts protons resulting from neutron beta decay. A new method is being implemented at J-PARC / MLF / BL05 using a pulsed cold neutron beam. A Time Projection Chamber (TPC) records both the electrons from neutron beta decay and protons from the neutron-$^3$He capture reactions in order to estimate the neutron flux. Electron background signals require the largest correction and are source of uncertainty for this experiment. A solenoidal magnetic field can greatly reduce this background. The TPC drift region must be divided into three region in this case. A prototype detector was developed to study the multi drift layer TPC. The status of a study using a prototype detector is reported in this paper.

description: Robust calibration of vector optically pumped magnetometers (OPMs) is a nontrivial task, but increasingly important for applications requiring high-accuracy such as magnetic navigation, geophysics research, and space exploration. Here, we showcase a vector OPM that utilizes Rabi oscillations driven between the hyperfine manifolds of $^{87}$Rb to measure the direction of a DC magnetic field against the polarization ellipse structure of a microwave field. By relying solely on atomic measurements -- free-induction decay (FID) signals and Rabi measurements across multiple atomic transitions -- this sensor can detect drift in the microwave vector reference and compensate for systematic shifts caused by off-resonant driving, nonlinear Zeeman (NLZ) effects, and buffer gas collisions. To facilitate dead-zone-free operation, we also introduce a novel Rabi measurement that utilizes dressed-state resonances that appear during simultaneous Larmor precession and Rabi driving (SPaR). These measurements, performed within a microfabricated vapor cell platform, achieve an average vector accuracy of 0.46 mrad and vector sensitivities down to 11 $μ$rad$/\sqrt{\text{Hz}}$ for geomagnetic field strengths near 50 $μ$T. This performance surpasses the challenging 1-degree (17 mrad) accuracy threshold of several contemporary OPM methods utilizing atomic vapors with an electromagnetic vector reference.

description: We investigate electrical transport in a quantum wire of $N$ sites connected to an equal number $(N_i/2)$ of sources and drains of charges in bulk. Each source and drain injects and extracts charges at the same rate, respectively. We show that the linear-response electrical current is nonreciprocal in such a system when the arrangement of sources and drains breaks the system's parity. We prove that inelastic scattering is essential for nonreciprocity in this system. For this, we invoke a master equation description of classical charge transport in a similar system. The nonreciprocal current in quantum wire matches that in the classical model for $N_i/N \sim 1$, generating a finite scattering length much smaller than the length of the wire. The nonreciprocity in the quantum wire oscillates with wire length when $N_i/N \ll 1$, and it can vanish at specific lengths.

The tetraquark description of X and Z resonances is shown to be compatible with present limits on the non-observation of charged partners X^+-, of the X(3872) and the absence of a hyperfine splitting between two different neutral states. In the same picture, Z_c and Z_b particles are expected to form complete isospin triplets plus singlets. It is also explained why the decay rate into final states including quarkonia are suppressed with respect to those having open charm/beauty states.

description: This study presents new risk analysis tools and demonstrates the feasibility and applicability of these tools in the design verification of railway interlocking control systems and deadlock prevention in automated manufacturing systems. Our verification methodology consists of the following stages. First, we analyze the rules executed by the controller and extract a state machine model of the controller. Second, we compose safety, reliability, and operability system specifications using a propositional temporal logic. Finally, we use the model checker to check the state machine model of the system against its requirements. The verification approach allows an exhaustive search of all possible behaviors and scenarios. We verified two real railway interlocking control applications with 125 and 452 constraints respectively. Checking two opposing signal protection specifications involving 3 signals ranged between 74 and 1223 seconds depending on the size and the complexity of the interlocking. Traditional verification methods typically require several person weeks

description: Perturbative bulk reconstruction in AdS/CFT starts by representing a free bulk field $ϕ^{(0)}$ as a smeared operator in the CFT. A series of $1/N$ corrections must be added to $ϕ^{(0)}$ to represent an interacting bulk field $ϕ$. These corrections have been determined in the literature from several points of view. Here we develop a new perspective. We show that correlation functions involving $ϕ^{(0)}$ suffer from ambiguities due to analytic continuation. As a result $ϕ^{(0)}$ fails to be a well-defined linear operator in the CFT. This means bulk reconstruction can be understood as a procedure for building up well-defined operators in the CFT which thereby singles out the interacting field $ϕ$. We further propose that the difficulty with defining $ϕ^{(0)}$ as a linear operator can be re-interpreted as a breakdown of associativity. Presumably $ϕ^{(0)}$ can only be corrected to become an associative operator in perturbation theory. This suggests that quantum mechanics in the bulk is only valid in perturbation theory around a semiclassical bulk geometry.

description: This paper studies the effect of differences in the rate of technological progress between sectors on the relative sizes of those sectors in terms of revenues. There are two sectors: a stagnant sector, where productivity does not change over time, and a progressive sector, where costs decrease over time due to exogenous technological progress. We consider a conjectural variation approach to competition in the progressive sector which encompasses perfect competition, Cournot oligopoly and monopoly. The main result of the paper is that the share of the stagnant sector increases over time when demand in the progressive sector is inelastic. Under perfect competition, when initial production costs in the progressive sector are sufficiently low (so that demand is inelastic), the share of the stagnant sector rises over time. Whereas, when initial production costs are sufficiently high (so that demand is elastic), the relative size of the stagnant sector is U-shaped with respect to time. Under monopoly, the share of the stagnant sector always decreases over time. However, the decline in that share is much more rapid the higher are initial costs in the progressive sector. The interaction of market structure and price elasticity (or initial costs) determines how the relative sizes of sectors differing in productivity growth evolve over time. The relationship with the cost disease literature is discussed.
Un regard sur les institutions du travail social au Québec et en Ontario durant les premières vagues de la COVID-19

description: Quelle place a pris le travail social et quelles ont été les contributions des institutions du travail social en Ontario et au Québec durant les premières vagues de la COVID-19? Telle fut la question qui a guidé la rédaction de ce mémoire. Pour commencer le travail social-son historique, ses approches, le contexte de la Nouvelle gestion publique et finalement celui de la pandémie sont présentés. Ensuite, pour répondre à la question de recherche, des institutions clés de travail social en formation et en intervention dans les deux provinces: écoles de travail social, revues scientifiques, ordres et associations professionnelles ont été ciblés. Chez chacune d’elles, des activités, productions ou publications réalisées durant les premières vagues de la pandémie entre mars 2020 et mai 2021 ont été sélectionnées. Le concept d’adaptation secondaire de Goffman (1979) et de Callista Roy (1971) a été mobilisé pour l’analyse qualitative de dix-huit documents. L’adaptation secondaire a été concrétisée dans cette étude suivant quatre dimensions articulées au travail social (le partenariat, la recomposition professionnelle, le renforcement des capacités, l’émergence de nouvelles compréhensions). L’analyse met en lumière la diversité des contributions du travail social pendant les premières vagues de la pandémie. Plus spécifiquement, la recherche montre que les institutions et les professionnels du travail social ont mis en œuvre plusieurs types d’activités: de formation, d’intervention, de recherche, de publication, de témoignage, d’hommage, de financement et de prise de position sociopolitique. Le travail social a proposé un ensemble de mesures sociales et sanitaires en vue de 1-limiter la propagation de la maladie ; 2-apporter du soutien aux personnes (incluant les intervenant.e.s) particulièrement touchées par les problèmes générés par la pandémie ; 3-soutenir les étudiant.e.s dans leur formation à distance; 4-contribuer à une meilleure compréhension du rôle du travail social dans la société en général, et en contexte de crise pandémique en particulier.

description: We study the thermal evolution of hypernuclear compact stars constructed from covariant density functional theory of hypernuclear matter and parameterizations which produce sequences of stars containing two-solar-mass objects. For the input in the simulations, we solve the Bardeen-Cooper-Schrieffer gap equations in the hyperonic sector and obtain the gaps in the spectra of $Λ$, $Ξ^0$ and $Ξ^-$ hyperons. For the models with masses $M/M_{\odot} \ge 1.5$ the neutrino cooling is dominated by hyperonic direct Urca processes in general. In the low-mass stars the $(Λp)$ plus leptons channel is the dominant direct Urca process, whereas for more massive stars the purely hyperonic channels $(Σ^-Λ)$ and $(Ξ^-Λ)$ are dominant. Hyperonic pairing strongly suppresses the processes on $Ξ^-$s and to a lesser degree on $Λ$s. We find that intermediate-mass $1.5 \le M/M_{\odot} \le 1.8$ models have surface temperatures which lie within the range inferred from thermally emitting neutron stars, if the hyperonic pairing is taken into account. Most massive models with $M/M_{\odot} \simeq 2$ may cool very fast via the direct Urca process through the $(Λp)$ channel because they develop inner cores where the $S$-wave pairing of $Λ$s and proton is absent.

International Factors and Rising Authoritarianism in Southeast Asia: China’s Belt and Road Initiative and the role of elite coherence in Malaysia and Indonesia
Creators: name: Rancourt Duchesne, Samuel
Publisher: name: My University

description: The degradation of rights and democracy in Southeast Asia marked by the last five years has captured the world’s attention, initiating a prominent debate and vast literature about this increasingly salient issue. This paper acknowledges that there are domestic causes to this matter but chooses to focus on how international factors contribute to the rise of authoritarianism in Southeast Asia. To find out, it looks at two main hypotheses: China’s growing presence in Southeast Asia through its Belt and Road Initiative (BRI) and the Trump administration’s Asia policy. It looks at Malaysia and Indonesia, using the method of difference, to determine which hypothesis has the greatest impact. This paper is constructed of three arguments. The first concludes that China’s BRI is the most important vector of authoritarianism among the two hypotheses studied. It argues that the illiberal characteristics of the BRI, its holistic approach and its strategic vision make the initiative an effective enabler of illiberal propensities. Although Trump’s Asia policy does reinforce the degradation of rights and democracy in Southeast Asia, it lacks coherence and long-term engagement to have a substantive effect. Secondly, it claims that the effect of the BRI is conditional upon the cohesion of the ruling elite. If there is unanimity among elites to embrace the potential offered by the BRI, authoritarian tendencies will be stronger. On the contrary, divided elites will dampen such tendencies. Finally, this paper argues that the effects of the BRI on authoritarian tendencies in Southeast Asia, notwithstanding the position of the ruling elite, will not last if the enthusiasm for the Chinese initiative is not shared by civil society.
