description: We give a manifest supersymmetric description of A and B branes on Kahler manifolds using a completely local N=2 superspace formulation of the world-sheet nonlinear sigma-model in the presence of a boundary. In particular, we show that an N=2 superspace description of type A boundaries is possible, at least when the background is Kahler. This leads to an elegant and concrete setting for studying coisotropic A branes. Here, apgesan important role is played by the boundary potential, whose precise physical meaning remains to be fully understood. Duality transformations relating A and B branes in the presence of isometries are studied as well.

description: We study experimentally the slow growth of a single crack in polycarbonate films submitted to uniaxial and constant imposed stress. The specificity of fracture in polycarbonate films is the appearance of flame shaped macroscopic process zones at the tips of the crack. Supported by an experimental study of the mechanical properties of polycarbonate films, an analysis of the stress dependence of the mean ratio between the process zone and crack lengths, during the crack growth, show a quantitative agreement with the Dugdale-Barenblatt model of the plastic process zone. We find that the fracture growth curves obey strong scaling properties that lead to a well defined growth master curve.

description: In upcoming years, the number of Internet-of-Things (IoT) devices is expected to surge up to tens of billions of physical objects. However, while the IoT is often presented as a promising solution to tackle environmental challenges, the direct environmental impacts generated over the life cycle of the physical devices are usually overlooked. It is implicitly assumed that their environmental burden is negligible compared to the positive impacts they can generate. In this paper, we present a parametric framework based on hardware profiles to evaluate the cradle-to-gate carbon footprint of IoT edge devices. We exploit our framework in three ways. First, we apply it on four use cases to evaluate their respective production carbon footprint. Then, we show that the heterogeneity inherent to IoT edge devices must be considered as the production carbon footprint between simple and complex devices can vary by a factor of more than 150x. Finally, we estimate the absolute carbon footprint induced by the worldwide production of IoT edge devices through a macroscopic analysis over a 10-year period. Results range from 22 to 562 MtCO2-eq/year in 2027 depending on the deployment scenarios. However, the truncation error acknowledged for LCA bottom-up approaches usually lead to an undershoot of the environmental impacts. We compared the results of our use cases with the few reports available from Google and Apple, which suggest that our estimates could be revised upwards by a factor around 2x to compensate for the truncation error. Worst-case scenarios in 2027 would therefore reach more than 1000 MtCO2-eq/year. This truly stresses the necessity to consider environmental constraints when designing and deploying IoT edge devices.

The Weibull - Log Weibull Distribution for Interoccurrence Times of Earthquakes

description: By analyzing the Japan Meteorological Agency (JMA) seismic catalog for different tectonic settings, we have found that the probability distributions of time intervals between successive earthquakes --interoccurrence times-- can be described by the superposition of the Weibull distribution and the log-Weibull distribution. In particular, the distribution of large earthquakes obeys the Weibull distribution with the exponent $α_1 <1$, indicating the fact that the sequence of large earthquakes is not a Poisson process. It is found that the ratio of the Weibull distribution to the probability distribution of the interoccurrence time gradually increases with increase in the threshold of magnitude. Our results infer that Weibull statistics and log-Weibull statistics coexist in the interoccurrence time statistics, and that the change of the distribution is considered as the change of the dominant distribution. In this case, the dominant distribution changes from the log-Weibull distribution to the Weibull distribution, allowing us to reinforce the view that the interoccurrence time exhibits the transition from the Weibull regime to the log-Weibull regime.

description: We show that the shear viscosity of lambda phi^4 theory is sensitive at next-to-leading order to soft physics, which gives rise to subleading corrections suppressed by only a half power of the coupling, eta = [3033.54 + 1548.3 m_{th}/T] N T^3]/[ (N+2)/3 lambda^2], with m^2_th=(N+2)/72 lambda T^2. The series appears to converge about as well (or badly) as the series for the pressure.

description: We investigate the semi-inclusive production of hidden-charm exotic states, including $X(3872)$, $Z_c$, $Z_{cs}$ and the pentaquark $P_c$ states, in lepton-proton scattering processes. These hadrons are close to the thresholds of a pair of charm and anticharm hadrons, and are assumed to have hadronic molecular structure as their main components. In order to give order-of-magnitude estimates of the cross sections, we use Pythia to simulate the short-distance productions of the constituent hadrons, which then rescatter to form the exotic hadrons. The estimates for the $X(3872)$ and $Z_c(3900)^\pm$ are not in conflict with the upper limits measured at the COMPASS experiment for the exclusive photoproduction process. The results here indicate that the considered hidden-charm states can be copiously produced at the proposed electron-ion colliders EicC and US-EIC.

description: Tau decays into hadrons have a twofold interest: On the one hand, they are a clean environment for studying the hadronization of the left-handed current of QCD, while, on the other side, provide relevant dynamical information of the resonances that mediate these processes. Within an effective field theory-like framework, namely Resonance Chiral Theory, we analyse the decays ot the tau into K K pion modes and compare the results with CLEO and BaBar data. In this way, we provide bounds on the couplings entering our Lagrangian and predict the corresponding spectral functions. As a main result -and contrary to the bulk of theoretical studies and experimental analyses- we find vector current dominance on these decays.

The Hudson’s Bay Company and the management of long-distance trade, 1670-1730
Creators: name: Mancke, Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines the Hudson's Bay Company from 1670 to 1730 focussing on its management of long-distance trade, the way it maximized opportunities and minimized risk and uncertainty. The company's involvement in the London fur market, its procurement of trade goods, the barter trade in North America, and their interrelationship are analysed almost entirely from the perspective of the Committee in London which managed the company. The organization of these commercial details in the context of the seventeenth-and eighteenth-century economic world explain how the company coordinated the disparate spheres of its operation and how it survived the drop in fur prices which occurred shortly after its advent. Historiographically the paper relies heavily on a growing body of literature dealing with long-distance trade and the expansion of Europe. In this respect the work brings a new perspective to fur trade historiography.

Systematic Review of Electric Vehicles, Resilience, and Evacuations
Creators: Babaei, Mohammad Hossein

Publisher: name: University of Alberta Library
Year: 2024

Disasters significantly impact communities, often require large-scale evacuations, and damage key infrastructure (e.g., power, transportation). With growing electric vehicle (EV) adoption and electrification of transportation, governments and utilities may face significant power challenges during a disaster, especially during the evacuation stage. Low states-of-charge, sporadic charging infrastructure, or power outages could significantly hamper safe and effective evacuations. Yet, EVs also offer possible resilience benefits to emergency response by more easily charging electronics (e.g., mobile phones, radios, vital medical equipment) or sending power back to the grid through vehicle-to-grid (V2G) technology. To understand this dichotomy, this paper focuses on the use cases, benefits, and drawbacks of EVs in disasters and evacuations through a systematic review of current literature, reports, and sources. Overall, this review discovered EVs show promise as modes of transportation and mobile energy supply units during disasters and emergencies. However, crucial challenges such as charging infrastructure locations, upfront cost of resilience technologies, and user behavior remain understudied. We recommend that more dedicated research, evaluation programs, and demonstrations be conducted to overcome EV shortcomings and guide more realistic implementation of EV benefits.

description: The understanding of the physical processes that lead to the origin of matter in the early Universe, creating both an excess of matter over anti-matter that survived until the present and a dark matter component, is one of the most fascinating challenges in modern science. The problem cannot be addressed within our current description of fundamental physics and, therefore, it currently provides a very strong evidence of new physics. Solutions can either reside in a modification of the standard model of elementary particle physics or in a modification of the way we describe gravity, based on general relativity, or at the interface of both. We will mainly discuss the first class of solutions. Traditionally, models that separately explain either the matter-antimatter asymmetry of the Universe or dark matter have been proposed. However, in the last years there has also been an accreted interest and intense activity on scenarios able to provide a unified picture of the origin of matter in the early universe. In this review we discuss some of the main ideas emphasising primarily those models that have more chances to be experimentally tested during next years. Moreover, after a general discussion, we will focus on extensions of the standard model that can also address neutrino masses and mixing, since this is currently the only evidence of physics beyond the standard model coming directly from particle physics and it is, therefore, reasonable they might also provide a solution to the problem of the origin of matter in the universe.

description: Algorithms for quantum information processing are usually decomposed into sequences of quantum gate operations, most often realized with single- and two- qubit gates[1]. While such operations constitute a universal set for quantum computation, gates acting on more than two qubits can simplify the implementation of complex quantum algorithms[2]. Thus, a single three-qubit operation can replace a complex sequence of two-qubit gates, which in turn promises faster execution with potentially higher Fidelity. One important three-qubit operation is the quantum Toffoli gate which performs a NOT operation on a target qubit depending on the state of two control qubits. Here we present the first experimental realization of the quantum Toffoli gate in an ion trap quantum computer. Our implementation is particular effcient as we directly encode the relevant logic information in the motion of the ion string. [1] DiVincenzo, D. P.

description: Context. We present precise radial-velocity measurements of five solar-type stars observed with the HARPS Echelle spectrograph mounted on the 3.6-m telescope in La Silla (ESO, Chile). With a time span of more than 10 years and a fairly dense sampling, the survey is sensitive to low mass planets down to super-Earths on orbital periods up to 100 days. Aims. Our goal was to search for planetary companions around the stars HD39194, HD93385, HD96700, HD154088, and HD189567 and use Bayesian model comparison to make an informed choice on the number of planets present in the systems based on the radial velocity observations. These findings will contribute to the pool of known exoplanets and better constrain their orbital parameters. Methods. A first analysis was performed using the DACE (Data & Analysis Center for Exoplanets) online tools to assess the activity level of the star and the potential planetary content of each system. We then used Bayesian model comparison on all targets to get a robust estimate of the number of planets per star. We did this using the nested sampling algorithm PolyChord. For some targets, we also compared different noise models to disentangle planetary signatures from stellar activity. Lastly, we ran an efficient MCMC (Markov chain Monte Carlo) algorithm for each target to get reliable estimates for the planets' orbital parameters. Results. We identify 12 planets within several multiplanet systems. These planets are all in the super-Earth and sub-Neptune mass regime with minimum masses ranging between 4 and 13 M$_\oplus$ and orbital periods between 5 and 103 days. Three of these planets are new, namely HD 93385 b, HD 96700 c, and HD 189567 c.

description: We analyze (2+1)-dimensional gravity with a Chern--Simons term and a negative cosmological constant, primarily at the weak field level. The full theory is expressible as the sum of two higher derivative SL(2,R) "vector" Chern-Simons terms, while the physical bulk degrees of freedom correspond to a single massive scalar field, just as for Lambda=0. The interplay of Lambda and the mass parameter mu can be studied, and any physical mass--including the conformal value with null propagation--is accessible by tuning mu. The single bulk mode yields a complete set of normalizable positive energy wave packets, as long as one chooses the usual, "wrong" sign of G necessary to connect smoothly with the known Lambda=0 limit. The chiral Chern--Simons coupling leads to gauge invariant linearized curvatures propagating with chirality-dependent masses. Linearized metric fluctuations have a finite asymptotic Fefferman--Graham expansion about the Poincar'e metric for any mass value greater or equal to a "critical" one, where various amusing effects appear, such as vanishing of one of the two "vector" Chern-Simons terms and an equivalence between tensor and vector excitations. We also find a set of chiral, pp-wave metrics that exactly solve the full nonlinear equations.

description: RESUMO – O Cinturão Sul do Cobre (CSC), na Província Mineral de Carajás (PMC), concentra importantes depósitos tipo-IOCG de classe mundial. Esta província é formada pelas rochas crustais mais antigas do Cráton Amazônico, compreendendo os domínios tectônicos Rio Maria, ao sul, e Carajás, ao norte, limitados por uma descontinuidade regional E-W. No CSC, localiza-se a Mina Sossego e os depósitos Alvo 118 e Cristalino, de classe mundial, além de Bacaba, Bacuri e Castanha, de menor tonelagem. Estudos diversos debatem quanto as gêneses destes depósitos e grande parte as relaciona diretamente com três grandes eventos intrusivos: em 2760-2740 Ma, 2570 Ma e 1880 Ma. Estes eventos ígneos tem sido considerados fundamentais no estabelecimento de um sistema magmático-hidrotermal responsável pela mobilização de fluidos e deposição de minério. A existência de amplos intervalos entre episódios dificulta, no entanto, o estabelecimento de modelos genéticos e geotectônicos consistentes. Assim, o desenvolvimento de parâmetros isotópicos índices de prospecção mineral se torna complexo. Neste sentido, houve o levantamento completo de dados geocronológicos e isotópicos existentes da área, para análise e validação. Um banco de dados georreferenciados, contendo geocronologia, tipos de alteração, paragênese, acompanhado de estruturas e assinaturas geofísicas foi elaborado. Com base nisso, gerou-se mapas geocronológicos preliminares e, assim, um novo plano amostral. Tal plano englobou depósitos da zona, como Sossego e Bacaba, além de rochas encaixantes e do embasamento. U-Pb SHRIMP em zircão e 40Ar39Ar step-heating em minerais hidrotermais forneceram novas idades. Estes dados, em conjunto com os levantamentos realizados, apontam para um evento hidrotermal regional em cerca de 2,1-2,2 Ga, amplamente relacionado às grandes estruturas e coevo ao Ciclo Transamazônico. Análises de elementos terras-raras (ETR) em zircão, via SHRIMP, permitiram verificar o comportamento destes elementos e individualizar populações de zircões: (i) cristais magmáticos, (ii) magmáticos hidrotermalmente afetados e (iii) hidrotermais. Com este estudo, objetiva-se estabelecer padrões elementares, avaliando assim as características do fluido hidrotermal e, caso possível, a individualização de cada episódio de hidrotermalismo. A associação entre estes processos hidrotermais, idades dos eventos e relações com a mineralização irão contribuir na compreensão da influência do Ciclo Transamazônico nos depósitos minerais da PMC.

description: This paper addresses the trajectory tracking problem of an autonomous tractor-trailer system by using a decentralized control approach. A fully decentralized model predictive controller is designed in which interactions between subsystems are neglected and assumed to be perturbations to each other. In order to have a robust design, a tube-based approach is proposed to handle the differences between the nominal model and real system. Nonlinear moving horizon estimation is used for the state and parameter estimation after each new measurement, and the estimated values are fed to robust tube-based decentralized nonlinear model predictive controller. The proposed control scheme is capable of driving the tractor-trailer system to any desired trajectory ensuring high control accuracy and robustness against neglected subsystem interactions and environmental disturbances. The experimental results show an accurate trajectory tracking performance on a bumpy grass field.

description: RESUMO - Considerada como uma das maiores e mais preservadas “sinéclises intracratônicas” do mundo, a Bacia do Paraná registra importantes eventos tectônicos, climáticos e bioestratigráficos, que compõem boa parte do Fanerozóico. Desde os estudos embrionários da Comissão Geográfica e Geológica da Província de São Paulo, a Bacia do Paraná, no Brasil, conta com minuciosos estudos estratigráficos e paleontológicos que representam um marco pioneiro na construção do pensamento moderno e atualístico no que diz respeito à evolução da teoria de tectônica de placas. Sob a ótica da literatura moderna, a sedimentação da Bacia do Paraná, durante o Eopaleozóico, possivelmente teve a influência da sobrecarga litostática relacionada à colisão de blocos alóctones junto à margem pericratônica sudoeste do paleocontinente Gondwana. A fragmentação do Supercontinente Rodinia e abertura do paleooceano Panthalassa produziram aulacógenos que foram reativados durante a colisão de terrenos suspeitos provenientes do Cráton da América do Norte (Laurentia + Greenville) com o proto-continente Gondwana (Orogenia Oclóyica). O Grupo Rio Ivaí (455 Ma a 430 Ma) apresenta geometria assimétrica com maiores espessuras para oeste, em direção ao Paraguai. Paleocorrentes dirigidas para oeste sugerem que o Arco de Assunção ainda não tinha expressão geomorfológica, tendo a Bacia do Paraná continuidade física com as bacias ChacoParaná e Chaco-Tarija. Novos mapas de integração sugerem que o sistema de falhas do Transbrasiliano estava ativo durante a sedimentação do Grupo Rio Ivaí, limitando e direcionando as curvas de iso-espessuras com geometria em mapa, similar às unidades de anti-país da porção boliviana. Após hiato deposicional de ~70 Ma, e com a instalação do segundo evento orogenético (Orogenia Precordilherana), iniciou-se mais um ciclo transgressivo-regressivo, a partir do qual foi depositado o Grupo Paraná (420 Ma a 360 Ma). A expressão em mapa da Formação Furnas sugere geometria dos depocentros de sedimentação muito similar a do Grupo Rio Ivaí, o que não acontece com a Formação Ponta Grossa. Para investigar essas hipóteses, até o momento foram coletadas amostras de exposições chave para que as futuras interpretações de proveniência a partir de estudo isotópico por U-Pb e Lu-Hf em zircão detrítico, se sustentem com as bases litoestratigráficas já bem estabelecidas na região.

Novel Sets of Coupling Expansion Parameters for low-energy pQCD

description: In quantum theory, physical amplitudes are usually presented in the form of Feynman perturbation series in powers of coupling constant $\al .$ However, it is known that these amplitudes are not regular functions at $α=0 .$ For QCD, we propose new sets of expansion parameters ${\bf w}_k(\as)$ that reflect singularity at $\as=0 $ and should be used instead of powers $\as^k.$ Their explicit form is motivated by the so called Analytic Perturbation Theory. These parameters reveal saturation in a strong coupling case at the level $\as^{eff}(\as\gg1)={\bf w}_1(\as\gg 1) \sim 0.5 .$ They can be used for quanitative analysis of divers low-energy amplitudes. We argue that this new picture with non-power sets of perturbation expansion parameters, as well as the saturation feature, is of a rather general nature.

Plastic pellets in sandy beaches: mechanisms and deposition indicators

description: ABSTRACT In the coastal zone, the plastic found is the result of the mismanagement of this kind of waste, particularly in developing countries. The material comes directly from the dispose of offshore by vessels (fishing debris) and by marine currents and winds, as well as urban drainage systems, rivers and/or estuaries. Specifically, in the plastic pellets case, which are spheres with 2-5 mm that constitute the raw material for the manufacture of plastic products, the Santos Port and the plastic factories in Cubatão city, are considered the main local sources of this input at the (environment of the) São Paulo coast. Consequently, the beaches most affected for this pollutant are those near Santos estuary, like Enseada do Guarujá beach. However, some questions are still open, such as: what are the mechanisms which control the pellets deposition, and which locations are most favorable for deposition on the beach? Thus, to develop this work it took four steps: 1) Plastic pellets geodetic survey based on GNSS positioning; 2) Beach geomorphometric parameters (altitude, aspect, and slope) derived by Digital Elevation Model (DEM); 3) Strandline altitude estimated by WaveWatch III (WW3) wave model analysis and tide height; and, 4) Plastic pellets deposition Suitability Index (PSI). The joint analysis of the altimetric, geomorphometric and meteoceanographic aspects showed that the beach areas with altitudes higher than those calculated for the strandline (> 2.06 m), slope ~ 3º and facing the same direction of the higher energy waves (175 - 195°) were more susceptible to pellet deposition. This indicates that the accumulation of this pollutant on the beach is controlled not only by its physical characteristics but mainly by storm surge events. Besides, the work also guides future research surveys optimizing time and avoiding subsamples, as well as beach cleaning. Another advantage brought by the methodology is that: when working with a geodetic reference (fixed, univocal and relatively stable on time), the information collected can be compared with other beaches anywhere on the planet — thus contributing to a standardization of the survey methodology.

Partons and jets at strong coupling from AdS/CFT

description: Calculations using the AdS/CFT correspondence can be used to unveil the short-distance structure of a strongly coupled plasma, as it would be seen by a `hard probe'. The results of these calculations admit a natural physical interpretation in terms of parton evolution in the plasma: via successive branchings, essentially all partons cascade down to very small values of the longitudinal momentum fraction x and to transverse momenta smaller than the saturation momentum Q_s\sim T/x. This scale Q_s controls the energy loss and the transverse momentum broadening of an energetic jet propagating through the plasma. This picture has some striking consequences, like the absence of jets in electron-proton annihilation at strong coupling, of the absence of particle production at forward and backward rapidities in hadron-hadron collisions, which look very different from the corresponding predictions of perturbative QCD and also from the known experimental situation.

Constraining planetesimal stirring: how sharp are debris disc edges?

Publisher: name: arXiv

description: The dust production in debris discs by grinding collisions of planetesimals requires their orbits to be stirred. However, stirring levels remain largely unconstrained, and consequently the stirring mechanisms as well. This work shows how the sharpness of the outer edge of discs can be used to constrain the stirring levels. Namely, the sharper the edge is the lower the eccentricity dispersion must be. For a Rayleigh distribution of eccentricities ($e$), I find that the disc surface density near the outer edge can be parametrised as $\tanh[(r_{\max}-r)/l_{\rm out}]$, where $r_{\max}$ approximates the maximum semi-major axis and $l_{\rm out}$ defines the edge smoothness. If the semi-major axis distribution has sharp edges $e_\mathrm{rms}$ is roughly $1.2 l_{\rm out}/r_{\max}$, or $e_\mathrm{rms}=0.77 l_{\rm out}/r_{\max}$ if semi-major axes have diffused due to self-stirring. This model is fitted to ALMA data of five wide discs: HD 107146, HD 92945, HD 206893, AU Mic and HR 8799. The results show that HD 107146, HD 92945 and AU Mic have the sharpest outer edges, corresponding to $e_\mathrm{rms}$ values of $0.121\pm0.05$, $0.15^{+0.07}_{-0.05}$ and $0.10\pm0.02$ if their discs are self-stirred, suggesting the presence of Pluto-sized objects embedded in the disc. Although these stirring values are larger than typically assumed, the radial stirring of HD 92945 is in good agreement with its vertical stirring constrained by the disc height. HD 206893 and HR~8799, on the other hand, have smooth outer edges that are indicative of scattered discs since both systems have massive inner companions.

Exclusive Double Charmonium Production from $Υ$ Decay

description: The exclusive decay of $Υ$ to a vector plus pseudoscalar charmonium is studied in perturbative QCD. The corresponding branching ratios are predicted to be of order $10^{-6}$ for first three $Υ$ resonances, and we expect these decay modes should be discovered in the prospective high-luminosity $e^+e^-$ facilities such as super $B$ experiment. As a manifestation of the short-distance loop contribution, the relative phases among strong, electromagnetic and radiative decay amplitudes can be deduced. It is particularly interesting to find that the relative phase between strong and electromagnetic amplitudes is nearly orthogonal. The resonance-continuum interference effect for double charmonium production near various $Υ$ resonances in $e^+e^-$ annihilation is addressed.

description: In a recent Letter [A. Lapolla and A. Godec, Phys. Rev. Lett. 125, 110602 (2020)], thermal relaxation was observed to occur faster from cold to hot (heating) than from hot to cold (cooling). Here we show that overdamped diffusion in anharmonic potentials generically exhibits both faster heating and faster cooling, depending on the initial temperatures and on the potential's degree of anharmonicity. We draw a relaxation-speed phase diagram that localises the different behaviours in parameter space. In addition to faster-heating and faster-cooling regions, we identify a crossover region in the phase diagram, where heating is initially slower but asymptotically faster than cooling. The structure of the phase diagram is robust against the inclusion of a confining, harmonic term in the potential as well as moderate changes of the measure used to define initially equidistant temperatures.

description: We study numerically localised short circuits in Li||Bi liquid metal batteries. In the prototype of a classical, three liquid-layer system, we assume a perceptible local deformation of the Li-salt interface. We find that there always exists a critical current at which a Li-droplet is cut off from this hump, and transferred to the Bi-phase. In a second case, we assume that the molten Li is contained in a metal foam, and that a small Li-droplet emerges below this foam due to insufficient wetting. This droplet is deformed by Lorentz forces, until eventually being pinched off. Here, the critical current is slightly lower than in the three-layer system, and both, a droplet transfer and complete short circuits are observed. Finally, we discuss the relevance of our simulations for experimentally observed short circuits and non-faradaic Li-transfer.

description: Recently, the LIGO-Virgo collaborations have reported the coalescence of a binary involving a black hole and a low-mass gap object (LMGO) with mass in the range $\sim2.5-5M_\odot$. Such detections, challenge our understanding of the black hole and neutron star mass spectrum, as well as how such binaries evolve especially if isolated. In this work we study the dynamical formation of compact object pairs, via multiple binary-single exchanges that occur at the cores of globular clusters. We start with a population of binary star systems, which interact with single compact objects as first generation black holes and LMGOs. We evaluate the rate of exchange interactions leading to the formation of compact object binaries. Our calculations include all possible types of binary-single exchange interactions and also the interactions of individual stars with compact object binaries that can evolve their orbital properties, leading to their eventual merger. We perform our calculations for the full range of the observed Milky Way globular cluster environments. We find that the exchanges are efficient in forming hard compact object binaries at the cores of dense astrophysical stellar environments. Furthermore, if the population size of the LMGOs is related to that of neutron stars, the inferred merger rate density of black hole-LMGO binaries inside globular clusters in the local Universe is estimated to be about $0.1 \, \text{Gpc}^{-3}\text{yr}^{-1}$.
