description: Confining gauge theories contain glueballs and mesons with arbitrary spin, and these particles become metastable at large $N$. However, metastable higher spin particles, when coupled to gravity, are in conflict with causality. This tension can be avoided only if the gravitational interaction is accompanied by interactions involving other higher spin states well below the Planck scale $M_{\rm pl}$. These higher spin states can come from either the QCD sector or the gravity sector, but both these resolutions have some surprising implications. For example, QCD states can resolve the problem since there is a non-trivial mixing between the QCD sector and the gravity sector, requiring all particles to interact with glueballs at tree-level. If gravity sector states restore causality, any weakly coupled UV completion of the gravity-sector must have many stringy features, with an upper bound on the string scale. Under the assumption that gravity is weakly coupled, both scenarios imply that the theory has a stringy description above $N\gtrsim \frac{M_{\rm pl}}{Λ_{\rm QCD}}$, where $Λ_{\rm QCD}$ is the confinement scale.

description: The physics reach of a low threshold (100 eV) scintillating argon bubble chamber sensitive to Coherent Elastic neutrino-Nucleus Scattering (CE$ν$NS) from reactor neutrinos is studied. The sensitivity to the weak mixing angle, neutrino magnetic moment, and a light $Z'$ gauge boson mediator are analyzed. A Monte Carlo simulation of the backgrounds is performed to assess their contribution to the signal. The analysis shows that world-leading sensitivities are achieved with a one-year exposure for a 10 kg chamber at 3 m from a 1 MW$_{th}$ research reactor or a 100 kg chamber at 30 m from a 2000 MW$_{th}$ power reactor. Such a detector has the potential to become the leading technology to study CE$ν$NS using nuclear reactors.

description: Questo articolo approfondisce alcuni aspetti della poesia di Milo De Angelis, uno dei più importanti poeti del secondo Novecento, grazie a un confronto con l’opera di Franco Fortini. L’immaginario politico è ciò che apparentemente più separa Fortini, il poeta engagé per eccellenza del Novecento, e De Angelis, da alcuni considerato simbolo del postmoderno in poesia e della cultura del riflusso. Individuare i punti di intersezione è utile per fare alcune considerazioni sul rapporto fra poesia e politica dopo gli anni Settanta. Il lavoro comprende l’analisi di due testi di De Angelis, tratti entrambi da Somiglianze (Guanda, 1976); mi servirò inoltre delle sue traduzioni e dichiarazioni di poetica.

Meaningful work and childhood stress
Creators: name: Naylor, Carol Anne
Publisher: name: University of British Columbia
Year: 2009

description: A multiple case study method was used to investigate the relationship between adult experiences of meaningful work and childhood experiences of existential stress. Three male participants were selected on the basis that they were engaged in personally meaningful work. In-depth interviews were used to collect stories from their childhood and current work life. Childhood and work narratives were transcribed from taperecorded interviews. Each account was reviewed and validated by the case study participants. The accounts were analyzed by comparing the childhood and work narrative plots and the participant's role within these plots. An analysis of the narratives revealed a pattern of experience that was common to all three cases. Overall, participants were found to play similar roles in their childhood and work narratives. In childhood, participants did not feel equipped to fulfill the role in which they were cast. As a result, participants were repeatedly cast in dramas in which the overriding stress of their childhood was played out. In work, however, participants were able to fulfill their roles and were engaged in activities that were instrumental in producing desired outcomes. Those activities cited as meaningful were directly and symbolically related to the resolution of the central stress from their childhood. Several implications emerge from this study. First, the study supports the findings of previous researchers who describe a relationship between childhood stress and meaningful work. Second, it describes a very complex relationship that includes such factors as an individual's sense of agency, enactments of family dramas, re-targeting sources of resolution, and engagement in significant activities. Third, it lends support for the practicability and usefulness of narrative approaches to career counselling. Finally, it supports the idea that meaningful work does not belong only to extraordinary or gifted people.
Relieving the $H_0$ tension with a new interacting dark energy model

description: We investigate an extended cosmological model motivated by the asymptotic safety of gravitational field theory, in which the matter and radiation densities and the cosmological constant receive a correction parametrized by the parameters $δ_G$ and $δ_Λ$, leading to that both the evolutions of the matter and radiation densities and the cosmological constant slightly deviate from the standard forms. Here we explain this model as a scenario of vacuum energy interacting with matter and radiation. We consider two cases of the model: {(i) ${\tildeΛ}$CDM with one additional free parameter $δ_G$, with $δ_{\rm G}$ and $δ_Λ$ related by a low-redshift limit relation and (ii) e${\tildeΛ}$CDM with two additional free parameters $δ_G$ and $δ_Λ$ that are independent of each other.} We use two data combinations, CMB+BAO+SN (CBS) and CMB+BAO+SN+$H_0$ (CBSH), to constrain the models. We find that, in the case of using the CBS data, neither ${\tildeΛ}$CDM nor e${\tildeΛ}$CDM can effectively alleviate the $H_0$ tension. However, it is found that using the CBSH data the $H_0$ tension can be greatly relieved by the models. In particular, in the case of e${\tildeΛ}$CDM, the $H_0$ tension can be resolved to 0.71$σ$. We conclude that as an interacting dark energy model, ${\tildeΛ}$CDM is much better than $Λ(t)$CDM in the sense of both relieving the $H_0$ tension and fitting to the current observational data.

description: The transverse response function R_T(q,omega) for 3He is calculated using the configuration space BonnA nucleon-nucleon potential, the Tucson-Melbourne three-body force, and the Coulomb potential. Final states are completely taken into account via the Lorentz integral transform technique. Non-relativistic one-body currents plus two-body pi- and rho-meson exchange currents as well as the Siegert operator are included. The response R_T is calculated for q=174, 250, 400, and 500 MeV/c and in the threshold region at q=174, 324, and 487 MeV/c. Strong MEC effects are found in low- and high-energy tails, but due to MEC there are also moderate enhancements of the quasi-elastic peak (6%-10%). The calculation is performed both directly and via transformation of electric multipoles to a form that involves the charge operator. The contribution of the latter operator is suppressed in and below the quasielastic peak while at higher energies the charge operator represents almost the whole MEC contribution at the lowest q value. The effect of the Coulomb force in the final state interaction is investigated for the threshold region at q=174 MeV/c. Its neglect enhances R_T by more than 10% in the range up to 2 MeV above threshold. In comparison to experimental data one finds relatively good agreement at q=250 and 400 MeV/c, while at q=500 MeV/c, presumably due to relativistic effects, the theoretical quasi-elastic peak position is shifted to somewhat higher energies. The strong MEC contributions in the threshold region are nicely confirmed by data at q=324 and 487 MeV/c.

description: The composition of Solar System surfaces can be inferred through reflectance and emission spectroscopy, by comparing these observations to laboratory measurements and radiative transfer models. While several populations of objects appear to be covered by sub-micrometre sized particles (referred to as hyperfine), there are limited studies on reflectance and emission of particulate surfaces composed of particles smaller than the visible and infrared wavelengths. We have undertaken an effort to determine the reflectance of hyperfine particulate surfaces in conjunction with high-porosity, in order to simulate the physical state of cometary surfaces and their related asteroids (P- and D-types). In this work, we present a technique developed to produce hyperfine particles of astrophysical relevant materials. Hyperfine powders were prepared and measured in reflectance in the 0.4-2.6 micrometer range. These powders were then included in water ice particles, sublimated under vacuum, in order to produce a hyperporous sample of hyperfine material. When grinded below one micrometre, the four materials studied (olivine, smectite, pyroxene and amorphous silica), show strong decrease of their absorption features together with a blueing of the spectra. This small grain degeneracy implies that surfaces covered by hyperfine grains should show only shallow absorption features if any. These two effects, decrease of band depth and spectral blueing, appear magnified when the grains are incorporated in the hyperporous residue. We interpret the distinct behaviour between hyperporous and more compact surfaces by the distancing of individual grains and a decrease in the size of the elemental scatterers. This work implies that hyperfine grains are unabundant at the surfaces of S- or V-type asteroids, and that the blue nature of B-type may be related to a physical effect rather than a compositional effect.

description: The need to accurately estimate the speed of road vehicles is becoming increasingly important for at least two main reasons. First, the number of speed cameras installed worldwide has been growing in recent years, as the introduction and enforcement of appropriate speed limits is considered one of the most effective means to increase the road safety. Second, traffic monitoring and forecasting in road networks plays a fundamental role to enhance traffic, emissions and energy consumption in smart cities, being the speed of the vehicles one of the most relevant parameters of the traffic state. Among the technologies available for the accurate detection of vehicle speed, the use of vision-based systems brings great challenges to be solved, but also great potential advantages, such as the drastic reduction of costs due to the absence of expensive range sensors, and the possibility of identifying vehicles accurately. This paper provides a review of vision-based vehicle speed estimation. We describe the terminology, the application domains, and propose a complete taxonomy of a large selection of works that categorizes all stages involved. An overview of performance evaluation metrics and available datasets is provided. Finally, we discuss current limitations and future directions.

description: We present a new method for analyzing the global stability of the Sedov-von Neumann-Taylor self-similar solutions, describing the asymptotic behavior of spherical decelerating shock waves, expanding into ideal gas with density \propto r^{-ω}. Our method allows to overcome the difficulties associated with the non-physical divergences of the solutions at the origin. We show that while the growth rates of global modes derived by previous analyses are accurate in the large wave number (small wavelength) limit, they do not correctly describe the small wave number behavior for small values of the adiabatic index γ. Our method furthermore allows to analyze the stability properties of the flow at early times, when the flow deviates significantly from the asymptotic self-similar behavior. We find that at this stage the perturbation growth rates are larger than those obtained for unstable asymptotic solutions at similar [γ,ω]. Our results reduce the discrepancy that exists between theoretical predictions and experimental results.

description: We start up the study of the stability of general graph pairs. This notion is a generalization of the concept of the stability of graphs. We say that a pair of graphs $(Γ,Σ)$ is stable if $Aut(Γ\timesΣ) \cong Aut(Γ)\times Aut(Σ)$ and unstable otherwise, where $Γ\timesΣ$ is the direct product of $Γ$ and $Σ$. An unstable graph pair $(Γ,Σ)$ is said to be a nontrivially unstable graph pair if $Γ$ and $Σ$ are connected coprime graphs, at least one of them is non-bipartite, and each of them has the property that different vertices have distinct neighbourhoods. We obtain necessary conditions for a pair of graphs to be stable. We also give a characterization of a pair of graphs $(Γ, Σ)$ to be nontrivially unstable in the case when both graphs are connected and regular with coprime valencies and $Σ$ is vertex-transitive. This characterization is given in terms of the $Σ$-automorphisms of $Γ$, which are a new concept introduced in this paper as a generalization of both automorphisms and two-fold automorphisms of a graph.

description: «La Francia non è Michel Houellebecq, non è intolleranza, odio e paura», affermava il primo ministro Valls nel corso della prima intervista successiva agli attentati parigini. In quei giorni come recitavano i nostri status e le immagini dei profili dei nostri social network, eravamo tutti Charlie ma nessuno o in pochissimi al di fuori della Francia erano a conoscenza di cosa fosse “Charlie Hebdo” assurto improvvisamente a epitome universale della libertà d’espressione. E in pochissimi probabilmente avevano letto Houellebecq, pur rinnegandolo, per non ricadere dalla parte opposta della coscienza, ammansiti dalla consapevolezza provvisoria della possibilità netta di essere nel giusto. Era stata colpita al cuore quella Francia che ha inciso a fuoco la parola libertà nel DNA della propria storia e della propria identità. All’indomani degli attentati parigini, il testo di Houellebecq ha di fatto moltiplicato d’un colpo recensori e censori rimettendo in discussione il ruolo della letteratura come strumento d’interpretazione della contemporaneità.

description: The superradiant stability of a Kerr-Newman black hole and charged massive scalar perturbation is investigated. We treat the black hole as a background geometry and study the equation of motion of the scalar perturbation. From the radial equation of motion, we derive the effective potential experienced by the scalar perturbation. By a careful analysis of this effective potential, it is found that when the inner and outer horizons of Kerr-Newman black hole satisfy $\frac{r_-}{r_+}\leqslant\frac{1}{3}$ and the charge-to-mass ratios of scalar perturbation and black hole satisfy $ \frac{q}{μ}\frac{Q}{ M}>1 $, the Kerr-Newman black hole and scalar perturbation system is superradiantly stable.

description: We study the quantum ground state phases of the one-dimensional disordered Bose--Hubbard model with attractive interactions, realized by a chain of superconducting transmon qubits or cold atoms. We map the phase diagram using perturbation theory and exact diagonalization. Compared to the repulsive Bose--Hubbard model, the quantum ground state behavior is dramatically different. At strong disorder of the on-site energies, all the bosons localize into the vicinity of a single site, contrary to the Bose glass behavior of the repulsive model. At weak disorder, depending on hopping, the ground state is either superfluid or a W state, which is a multi-site and multi-particle entangled superposition of states where all the bosons occupy a single site. We show that the robustness of the W phase against disorder diminishes as the total number of bosons increases.
Painleve I asymptotics for orthogonal polynomials with respect to a varying quartic weight

description: We study polynomials that are orthogonal with respect to a varying quartic weight \exp(-N(x^2/2+tx^4/4)) for t<0, where the orthogonality takes place on certain contours in the complex plane. Inspired by developments in 2D quantum gravity, Fokas, Its, and Kitaev, showed that there exists a critical value for t around which the asymptotics of the recurrence coefficients are described in terms of exactly specified solutions of the Painleve I equation. In this paper, we present an alternative and more direct proof of this result by means of the Deift/Zhou steepest descent analysis of the Riemann-Hilbert problem associated with the polynomials. Moreover, we extend the analysis to non-symmetric combinations of contours. Special features in the steepest descent analysis are a modified equililbrium problem and the use of Psi-functions for the Painleve I equation in the construction of the local parametrix.

description: The recovery of the underlying low-rank structure of clean data corrupted with sparse noise/outliers is attracting increasing interest. However, in many low-level vision problems, the exact target rank of the underlying structure and the particular locations and values of the sparse outliers are not known. Thus, the conventional methods cannot separate the low-rank and sparse components completely, especially in the case of gross outliers or deficient observations. Therefore, in this study, we employ the minimum description length (MDL) principle and atomic norm for low-rank matrix recovery to overcome these limitations. First, we employ the atomic norm to find all the candidate atoms of low-rank and sparse terms, and then we minimize the description length of the model in order to select the appropriate atoms of low-rank and the sparse matrices, respectively. Our experimental analyses show that the proposed approach can obtain a higher success rate than the state-of-the-art methods, even when the number of observations is limited or the corruption ratio is high. Experimental results utilizing synthetic data and real sensing applications (high dynamic range imaging, background modeling, removing noise and shadows) demonstrate the effectiveness, robustness and efficiency of the proposed method.

description: Elliptical galaxies and their groups having the largest L_x/L_B lie close to the locus in the L_x,L_B diagram expected for closed systems with baryon fractions equal to the cosmic mean value, f_b = 0.16. The estimated baryon fractions for several of these galaxies/groups are also close to 0.16 when the gas density is extrapolated to the virial radius. Evidently they are the least massive baryonically closed systems. Gas retention in these groups implies that non-gravitational heating cannot exceed about 1 keV per particle, consistent with the heating required to produce the deviation of groups from the L_x - T correlation for more massive clusters. Isolated galaxies/groups with X-ray luminosities significantly lower than baryonically closed groups may have undermassive dark halos, overactive central AGNs, or higher star formation efficiencies. The virial mass and hot gas temperatures of nearly or completely closed groups correlate with the group X-ray luminosities and the optical luminosities of the group-centered elliptical galaxy, an expected consequence of their merging history. The ratio of halo mass to the mass of the central galaxy for X-ray luminous galaxy/groups is about 80.

Evaluation of an intensive group-process based model of team leadership development: implications for Canadian health care employees
Creators: name: Black, Timothy G.
Publisher: name: University of British Columbia
Year: 2009

description: The traditional model of leadership in medicine and health care generally centres around a hierarchical structure of power and influence, resting in the hands of a select few administrators, with limited input from employees. A newly developed Cancer treatment centre in the Province of British Columbia, Canada has attempted to institute a unique, team-based system of shared leadership and decision-making. In order to accomplish this task, the Senior Administrator of the centre hired professional group development experts to facilitate the formation of the newly established Leadership Team. A team of nine individuals participated in a group-process based model of team leadership development, consisting of a series of intensive weekend workshops. This study evaluates the impact of those intensive workshops on the members of the Cancer centre Leadership Team. Qualitative case-study methodology, combined with the use of indepth interviews, illuminated eight categories of shared experience among seven of the nine team members, as a result of having participated in the workshop series.

By assessing students' attitudes and satisfaction, educators gain a valuable affective perspective that allows for a more complete examination of strategy effectiveness. This paper examines teamwork satisfaction and student attitude towards online learning, while also highlighting elements of successful online collaboration as identified by students using the instruments developed by Hasler-Waters & Napier, Ku et al, and Tseng et al. This case study was carried out over a seven-week period with first-year engineering students (N=94), in a module entitled Design for Manufacture, during the COVID-19 pandemic. The findings revealed high levels of student satisfaction and attitudes towards working in teams in the online environment while participating in problem and project-based learning (PBL). Additionally, the findings outline multiple factors that affect the success of online collaboration. The relevance of these findings is then discussed in the context of an increasing move towards blended and online engineering education provision

description: We provide a microscopic-level derivation of earlier results showing that, in the critical vicinity of the superconductor-to-insulator transition (SIT), disorder and localization become negligible and the structure of the emergent phases is determined by topological effects arising from the competition between two quantum orders, superconductivity and superinsulation. We find that, around the critical point, the ground state is a composite incompressible quantum fluid of Cooper pairs and vortices coexisting with an intertwined Wigner crystal for the excess (with respect to integer filling) excitations of the two types.

description: We describe Serre functors for (generalisations of) the category O associated with a semi-simple complex Lie algebra. In our approach, projective-injective modules play an important role. They control the Serre functor in the case of a quasi-hereditary algebra having a double centraliser property with respect to a symmetric algebra. As an application of the double centraliser property and our description of Serre functors, we prove three conjectures of Khovanov about the projective-injective modules in the parabolic category O for sl_n.

Extreme mass-ratio gravitational-wave sources: Mass segregation and post binary tidal-disruption captures

description: The gravitational-wave (GW) inspirals of stellar-mass compact objects onto a supermassive black hole (MBH), are some of the most promising GW sources detectable by next-generation space-born GW-detectors. The rates and characteristics of such extreme mass ratio inspirals (EMRIs) sources are highly uncertain. They are determined by the dynamics of stars near MBHs, and the rate at which compacts objects are driven to the close proximity of the MBH. Here we consider weakly and strongly mass-segregated nuclear clusters, and the evolution of stars captured into highly eccentric orbits following binary disruptions by the MBH. We make use of a Monte-Carlo approach to model the diffusion of both captured objects, and compact-objects brought through two-body relaxation processes. We calculate the rates of GW-inspirals resulting from relaxation-driven objects, and characterize EMRIs properties. We correct previous studies and show that relaxation-driven sources produce GW-sources with lower-eccentricity than previously found, and provide the detailed EMRI eccentricity distribution in the weak and strong mass-segregation regimes. We also show that binary-disruption captured-stars could introduce low-eccentricity GW-sources of stellar black-hole EMRIs in mass-segregated clusters. The eccentricities of the GW-sources from the capture channel, however, are strongly affected by relaxation processes, and are significantly higher than previously suggested. We find that both the rate and eccentricity distribution of EMRIs could probe the dynamics near MBHs, and the contribution of captured stars, characterize the mass-function of stellar compact objects, and verify whether weak or strong mass-segregation processes take place near MBHs.

[ARTICLE] Extended Angle Sum and Difference Identity Rules for Scalene Triangles (Canadian Journal of Mathematics Research / 2022) - GAMMA TRIGONOMETRY

description: ABSTRACT The present article extends the applicability of the angle sum and difference identity rules sin(A±B) and cos(A±B) beyond the particular case of a right-angled triangle into the general case of scalene triangles as sin*(A±B,γ) and cos*(A±B,γ), adding the effect of independently varying both the reference angle α = A±B and the obtuse angle γ. Accompanied by appropriate theorems and proofs, the mathematical end result are four updated equations that supersede the traditional expressions sin(A±B) = sin(A)cos(b)± cos(A)sin(B) and cos(A±B) = cos(α)cos(B) ∓ sin(A) sin(B), where the conventional sin(α) and cos(α) functions are replaced by the [already proven] extended versions sin*(α,γ) and cos*(α,γ) enclosing modifications including two angles α and γ. An open-source program scripted in Octave is provided for the verification of the derived expressions, including plotting the geometric results as a figure for both the cases of angle summation and subtraction.

Stress-coping and individuation in enfp-type women : theoretical integration and development
Creators: name: Wolfe, Heather P.
Publisher: name: University of British Columbia
Year: 2009

description: Through a combination of grounded theory method and orientational qualitative inquiry, this study focused on integrating and building upon components of cognitive-transactional stress-coping theory (Lazarus & Folkman, 1984, Lazarus, 1991) and Jungian/Myers-Briggs type theory (Jung, 1921/1971, Myers & McCaulley, 1985) through the exploration of extraverted women's stresscoping processes. Six women (age range 31-42) scoring ENFP on the Myers- Briggs Type Indicator (Form G Self-Scorable, Revised) participated in semistructured interviews taking approximately 90 minutes each. Results indicated general categories of stress-related storing and releasing dynamics, involving both physical and psychological dimensions. The model developed focused mainly on stress involving people, as the women emphasized this as being more personally relevant than task-oriented stressors, and the examples given in their narratives reflected this emphasis. In addition to external behaviours, the results outline intrapsychic processes described by the women, including cognitive-emotional processing of the stressful events. Attention was given to meaning-making and self-actualizing through the stress-coping process (individuation). The women's interview narratives indicated a multifaceted appraisal process linked with issues involving ongoing identity consolidation and reintegration. An overall resulting theme of transcending stress is discussed, presented from an integrated cognitive-transactional and Jungian theoretical perspective. Future implications regarding research and counselling practice are noted.
The characteristics of the Galactic center excess measured with 11 years of Fermi-LAT data

description: The excess of $γ$ rays in the data measured by Fermi-LAT from the Galactic center region is one of the most intriguing mysteries in Astroparticle Physics. This Galactic center excess (GCE), has been measured with respect to different interstellar emission models (IEMs), source catalogs, data selections and techniques. Although several proposed interpretations have appeared in the literature, there are not firm conclusions as to its origin. The main difficulty in solving this puzzle lies in modeling a region of such complexity and thus precisely measuring the characteristics of the GCE. In this paper, we use 11 years of Fermi-LAT data, state of the art IEMs, and the newest 4FGL source catalog to provide precise measurements of the energy spectrum, spatial morphology, position, and sphericity of the GCE. We find that the GCE has a spectrum which is peaked at a few GeV and is well fit with a log-parabola. The normalization of the spectrum changes by roughly $60\%$ when using different IEMs, data selections and analysis techniques. The spatial distribution of the GCE is compatible with a dark matter (DM) template produced with a generalized NFW density profile with slope $γ= 1.2-1.3$. No energy evolution is measured for the GCE morphology between $0.6-30$ GeV at a level larger than $10\%$ of the $γ$ average value, which is 1.25. The analysis of the GCE modeled with a DM template divided into quadrants shows that the spectrum and spatial morphology of the GCE is similar in different regions around the Galactic center. Finally, the GCE centroid is compatible with the Galactic center, with best-fit position between $l=[-0.3^{\circ},0.0^{\circ}],b=[-0.1^{\circ},0.0^{\circ}]$, and it is compatible with a spherical symmetric morphology. In particular, fitting the DM spatial profile with an ellipsoid gives a major-to-minor axis ratio between 0.8-1.2.

description: We investigate for the first time the enhancement of the stimulated Raman scattering in slow-light Silicon-on-Insulator (SOI) photonic crystal line defect waveguides. By applying the Bloch-Floquet formalism to the guided modes in a planar photonic crystal, we develop a formalism that relates the intensity of the down-shifted Stokes signal to the pump intensity and the modal group velocities. The formalism is then applied to two prospective schemes for enhanced stimulated Raman generation in slow-light photonic crystal waveguides. The results demonstrate a maximum factor of 10^4 (66,000) enhancement with respect to SOI channel waveguides. Effects of two photon absorption, intrinsic scattering, and disorder with respect to slow-light Raman generation towards optically-pumped silicon amplifiers and lasers are also discussed.

description: Deep reinforcement learning (DRL) algorithms and evolution strategies (ES) have been applied to various tasks, showing excellent performances. These have the opposite properties, with DRL having good sample efficiency and poor stability, while ES being vice versa. Recently, there have been attempts to combine these algorithms, but these methods fully rely on synchronous update scheme, making it not ideal to maximize the benefits of the parallelism in ES. To solve this challenge, asynchronous update scheme was introduced, which is capable of good time-efficiency and diverse policy exploration. In this paper, we introduce an Asynchronous Evolution Strategy-Reinforcement Learning (AES-RL) that maximizes the parallel efficiency of ES and integrates it with policy gradient methods. Specifically, we propose 1) a novel framework to merge ES and DRL asynchronously and 2) various asynchronous update methods that can take all advantages of asynchronism, ES, and DRL, which are exploration and time efficiency, stability, and sample efficiency, respectively. The proposed framework and update methods are evaluated in continuous control benchmark work, showing superior performance as well as time efficiency compared to the previous methods.
