description: Repeated observations with high spectral resolution acquired in 1998-2008 are used to study the temporal behavior of the spectral line profiles and velocity field in the atmosphere and circumstellar envelope of the post-AGB star V448Lac. Asymmetry of the profiles of the strongest absorption lines with low-level excitation potentials less 1eV and time variations of these profiles have been detected, most prominently the profiles of the resonance lines of BaII, YII, LaII, SiII. The peculiarity of these profiles can be explained using a superposition of stellar absorption line and shell emission lines. Emission in the (0;1) 5635A Swan band of the C2 molecule has been detected in the spectrum of V448Lac for the first time. The core of the Halpha line displays radial velocity variations with an amplitude ~8 km/s. Radial velocity variations displayed by weakest metallic lines with lower amplitudes, 1-2 km/s, may be due to atmospheric pulsations. Differential line shifts, 0 -- 8 km/s, have been detected on various dates. The position of the molecular spectrum is stationary in time, indicating a constant expansion velocity of the circumstellar shell, Vexp=15.2 km/s, as derived from the C2 and NaI lines.

description: Gyrochronology allows the derivation of ages for cool main sequence stars from their observed rotation periods and masses, or a suitable proxy of the latter. It is increasingly well explored for FGK stars, but requires further measurements for older ages and K-M-type stars. Recent work has shown that the behavior of stellar spindown differs significantly from prior expectations for late-type stars. We study the 4Gyr-old benchmark open cluster M67 to explore this behavior further. We combined a Gaia DR3 sample with the Kepler K2 superstamp of Campaign 5 around M67 and created new light curves from aperture photometry. The light curves are subjected to an extensive correction process to remove instrumental systematics and trending, followed by period analysis to measure stellar rotation. We identify periodic signals in 136 light curves, 47 of which are from the rotation of effectively single main-sequence stars that span from early-G to mid-M type. These results connect well to prior work on M67 and extend it to much later spectral types. We find that the rotation periods of single stars of age 4Gyr define a tight relationship with color, ranging from spectral types F through M. The corresponding surface of rotation period against age and mass is therefore well-defined to an older age than was previously known. However, the deviations from prior expectations of the stellar spindown behavior are even more pronounced at 4Gyr. The binary cluster members do not follow the single star relationship. The majority are widely scattered below the single star sequence. Consequently, they do not seem to be suitable for gyrochronology at present.

description: We present measurements of differential cross sections for the inclusive $Z/γ^*$ + jet production and the inclusive photon plus heavy flavor production in a data sample of 1fb$^{-1}$ collected with the DØdetector in proton-antiproton collisions at $\sqrt{s}$=1.96 TeV. In the first measurement, we compare kinematic distributions of the $Z/γ^*$ and the jets as well as various angles of the $Z$+jet system with different Monte Carlo event generators and next-to-leading order perturbative QCD (NLO pQCD) predictions with non-perturbative corrections applied. In the second measurement, we compare the results with NLO pQCD predictions, covering photon transverse momenta 30-150 GeV, photon rapidities $|y^γ| < 1.0$, jet rapidities $|y^{jet}| < 0.8$, and jet transverse momenta $p_{T}^{jet} > 15$ GeV.

description: significant potential for various applications due to their extended flight endurance. However, optimizing the design of solar-powered UAVs to achieve maximum efficiency and performance remains a complex challenge. The main objective of this research is to explore the sensitivity of solar-powered UAV mass to different design variables and technological constraints. The study employs a conceptual design methodology, iterating through various design configurations while specific design variables within bounds of historical data. Key parameters, including aspect ratio, wing span, payload mass, power consumption, cruise altitude, and technological constraints such as solar panel efficiency and battery energy density, are systematically varied to analyze their impact on UAV mass. The study also considers the influence cloud cover on solar power generation. This parametric study's results divulge solar-powered UAV mass's sensitivity to these design variables and technological constraints. By identifying key factors influencing UAV mass, the study offers actionable insights for designers and engineers in aerospace industry. The findings contribute to advancing the understanding of solar-powered UAV technology and lay the groundwork for future research and development initiatives to enhance UAV performance and efficiency.

description: We compute the equilibrium, the fundamental eigenfrequency of oscillations modes, and quadrupolar tidal deformability of anisotropic polytropic spheres. These studies are respectively performed through the numerical solution of the Tolman-Oppenheimer-Volkoff equation, Chandrasekhar radial oscillation equations, and nonlinear first-order Riccati equation for tidal deformability, all modified from their original version to include the anisotropic effects. For the polytropic exponent $γ=2$ and the anisotropic model of Cattoen, Faber, and Visser, we show that the anisotropy could be reflected in the radial pressure, energy density, speed of sound, radial stability, and tidal deformability.

description: Consider the problem of finding high dimensional approximate nearest neighbors, where the data is generated by some known probabilistic model. We will investigate a large natural class of algorithms which we call bucketing codes. We will define bucketing information, prove that it bounds the performance of all bucketing codes, and that the bucketing information bound can be asymptotically attained by randomly constructed bucketing codes. For example suppose we have n Bernoulli(1/2) very long (length d-->infinity) sequences of bits. Let n-2m sequences be completely independent, while the remaining 2m sequences are composed of m independent pairs. The interdependence within each pair is that their bits agree with probability 1/20. Moreover if one sequence out of each pair belongs to a a known set of n^{(2p-1)^{2}-ε} sequences, than pairing can be done using order n comparisons!

description: The equation of state (EoS) of neutron star (NS) matter is investigated considering kaon condensation. Moreover, the tidal parameters related to the components of binary neutron star mergers are determined and compared to the constraints of GW170817 imposed on these quantities. In this study, we employ the lowest-order constrained variational (LOCV) approach and utilize {AV6$'$, AV8$'$, and AV18 potentials} accompanied by the three nucleon interaction (TNI) {in order to consider the nucleon-nucleon interaction}. It is known that the existence of kaons in the core of NSs softens the EoS {and thus} lowers the value of maximum mass which is expected to be greater than 2 M$_\odot$. Our results demonstrate that considering kaon condensation with a strangeness value, a$_{3}$m$_s$=-134 MeV satisfies the maximum mass constraint except for AV8$'$+TNI potential. However, the calculation of dimensionless tidal deformability shows that with the decrease of strangeness value, the neutron star gets less deformed.

description: Game semantics has been used with considerable success in formulating fully abstract semantics for languages with higher-order procedures and a wide range of computational effects. Recently, nominal games have been proposed for modelling functional languages with names. These are ordinary, stateful games cast in the theory of nominal sets developed by Pitts and Gabbay. Here we take nominal games one step further, by developing a fully abstract semantics for a language with nominal general references.

description: The robustness of deep neural networks (DNNs) is crucial to the hosting system's reliability and security. Formal verification has been demonstrated to be effective in providing provable robustness guarantees. To improve its scalability, over-approximating the non-linear activation functions in DNNs by linear constraints has been widely adopted, which transforms the verification problem into an efficiently solvable linear programming problem. Many efforts have been dedicated to defining the so-called tightest approximations to reduce overestimation imposed by over-approximation. In this paper, we study existing approaches and identify a dominant factor in defining tight approximation, namely the approximation domain of the activation function. We find out that tight approximations defined on approximation domains may not be as tight as the ones on their actual domains, yet existing approaches all rely only on approximation domains. Based on this observation, we propose a novel dual-approximation approach to tighten over-approximations, leveraging an activation function's underestimated domain to define tight approximation bounds. We implement our approach with two complementary algorithms based respectively on Monte Carlo simulation and gradient descent into a tool called DualApp. We assess it on a comprehensive benchmark of DNNs with different architectures. Our experimental results show that DualApp significantly outperforms the state-of-the-art approaches with 100% - 1000% improvement on the verified robustness ratio and 10.64% on average (up to 66.53%) on the certified lower bound.

description: The main objective of this work was to study the reason for low accuracy and misclassified pixels in hybrid corn crop parcels. In this study, we employed Sentinel-2 (S-2) data and Fraction of Absorbed Photosynthetically Active Radiation (fAPAR) acquired between the beginning of April and September 2020, on Mezőhegyes town in south-eastern Hungary. A different set of spectral indices (SI) and fAPAR were applied as inputs to Random Forest (RF) and Support Vector Machine (SVM) algorithms to generate crop map. The research showed that despite the high overall accuracy (OA) classified map, there are might be an error or low pixel resolution on it which can be the result of the temporal, spatial, temporal characteristics and a condition in crop plants. We have found the cause of misclassification are due to overirrigation and high precipitation rate during the growing stage of hybrid corn. Moreover, almost 99% of affected hybrid corn areas are identified when the multi-temporal spectral bands (SB) and spectral indices (SI), in combination with fAPAR datasets were added.

description: Residuals in the Hubble diagram at optical wavelengths and host galaxy stellar mass are observed to correlate in Type Ia supernovae (SNe Ia) (`magnitude step'). Among possible progenitor channels for the associated explosions, those based on dark matter (DM) have attracted significant attention, including our recent proposal that `normal' SNe Ia from bare detonations in sub-Chandrasekhar white dwarf stars are triggered by the passage of asteroid-mass primordial black holes (PBHs): the magnitude step could then originate from a brightness dependence on stellar properties, on DM properties, or both. Here, we present a method to estimate the local DM density and velocity dispersion of the environment of SN Ia progenitors. We find a luminosity step of $0.52\pm 0.11\,$mag corresponding to bins of high vs low DM density in a sample of 222 low-redshift events from the Open Supernova Catalog. We investigate whether the magnitude step can be attributed to local DM properties alone, assuming asteroid-mass PBHs. Given the inverse correlation between SN Ia brightness and PBH mass, an intriguing explanation is a spatially-inhomogeneous PBH mass function. If so, a strong mass segregation in the DM density-dependent PBH mass scale is needed to explain the magnitude step. While mass segregation is observed in dense clusters, it is unlikely to be realized on galactic scales. Therefore, if DM consists of asteroid-mass PBHs, the magnitude step is more likely to exist, and dominantly to be attributed to local stellar properties.

description: We present photometry of 104 M31 globular clusters (GCs) and GC candidates in 15 intermediate-band filters of the Beijing-Arizona-Taiwan-Connecticut (BATC) photometric system. The GCs and GC candidates were selected from the Revised Bologna Catalog (v.3.5). We obtain the cluster ages by comparing the photometric data with up-to-date theoretical synthesis models. The photometric data used are {\sl GALEX} far- and near-ultraviolet and 2MASS near-infrared $JHK_{\rm s}$ magnitudes, combined with optical photometry. The ages of our sample clusters cover a large range, although most clusters are younger than 10 Gyr. Combined with the ages obtained in our series of previous papers focusing on the M31 GC system, we present the full M31 GC age distribution. The M31 GC system contains populations of young and intermediate-age GCs, as well as the `usual' complement of well-known old GCs, i.e., GCs of similar age as the majority of the Galactic GCs. In addition, young GCs (and GC candidates) are distributed nearly uniformly in radial distance from the center of M31, while most old GCs (and GC candidates) are more strongly concentrated.

PHRASEOLOGICAL AND CONCEPTUAL REPRESENTATIONS OF "WOMAN" IN RUSSIAN, ENGLISH, AND KARAKALPAK: A COMPARATIVE APPROACH
Creators: name: Ong'arbaeva, Gumisgul
Publisher: name: Zenodo
Year: 2024

description: This article presents a comparative analysis of the concept of "woman" in Russian, English, and Karakalpak languages, focusing on phraseological and conceptual representations. Drawing on linguistic and cultural studies, the research explores how proverbs, idioms, and other paremiological units in these languages reflect societal norms, gender stereotypes, and evolving roles assigned to women. The study demonstrates that while the concept of "woman" is universally recognized across the three languages, there are significant variations in how women are portrayed. Russian and English phraseological units often carry negative connotations, reflecting traditional gender biases, whereas the Karakalpak language, rooted in conservative traditions, portrays women with a mix of respect and established societal expectations. This comparative approach sheds light on the cognitive frameworks that shape gender perceptions and highlights the importance of language in both perpetuating and challenging cultural gender norms. Such insights contribute to broаder discussions on gender equality, cultural values, and the role of languаge in shaping social identity.

description: Recent anomalies in cosmic rays could be due to dark matter annihilation in our galaxy. In order to get the required large cross-section to explain the data while still obtaining the right relic density, we rely on a non standard thermal history between dark matter freeze-out and Big-Bang Nucleosynthesis (BBN). We show that through a reheating phase from the decay of a heavy moduli or even the gravitino, we can produce the right relic density of dark matter if its self-annihilation cross-section is large enough. In addition to fitting the recent data, this scenario solves the cosmological moduli and gravitino problems. We illustrate this mechanism with a specific example in the context of U(1)_{B-L} extended MSSM where supersymmetry is broken via mirage mediation. These string motivated models naturally contain heavy moduli decaying to the gravitino, whose subsequent decay to the LSP can reheat the universe at a low temperature. The right-handed sneutrino and the B-L gaugino can both be viable dark matter candidates with large cross-section. They are leptophilic because of B-L charges. We also show that it is possible to distinguish the non-thermal from the thermal scenario (using Sommerfeld enhancement) in direct detection experiments for certain regions of parameter space.

description: Doped strontium titanate SrTiO$_3$ (STO) is one of the most dilute superconductors known today. The fact that superconductivity occurs at very low carrier concentrations is one of the two reasons that the pairing mechanism is not yet understood, the other is the role played by the proximity to a ferroelectric instability. In undoped STO, ferroelectric order can in fact be stabilized by substituting $^{16}$O with its heavier isotope $^{18}$O. Here we explore the superconducting properties of doped and isotope-substituted SrTi$(^{18}$O$_{y}^{16}$O$_{1-y})_{3-δ}$ for $0\le y \le 0.81$ and carrier concentrations between $6\times 10^{17}$ and $2\times 10^{20}$ cm$^{-3}$ ($δ<0.02$). We show that the superconducting $T_c$ increases when the $^{18}$O concentration is increased. For carrier concentrations around $5\times 10^{19}$~cm$^{-3}$ this $T_c$ increase amounts to almost a factor $3$, with $T_c$ as high as 580~mK for $y=0.74$. When approaching SrTi$^{18}$O$_3$ the maximum $T_c$ occurs at a much smaller carrier densities than for pure SrTi$^{16}$O$_3$. Our observations agree qualitatively with a scenario where superconducting pairing is mediated by fluctuations of the ferroelectric soft mode.

description: A solid slender beam of length $L$, made from a material of Young's modulus $Y$ and subject to a gentle compressive force $F$, requires a volume of material proportional to $L^{3}f^{1/2}$ [where $f\equiv F/(YL^{2})\ll 1$] in order to be stable against Euler buckling. By constructing a hierarchical space frame, we are able to systematically change the scaling of required material with $f$ so that it is proportional to $L^{3}f^{(G+1)/(G+2)}$, through changing the number of hierarchical levels $G$ present in the structure. Based on simple choices for the geometry of the space frames, we provide expressions specifying in detail the optimal structures (in this class) for different values of the loading parameter $f$. These structures may then be used to create effective materials which are elastically isotropic and have the combination of low density and high crush strength. Such a material could be used to make light-weight components of arbitrary shape.

description: The Hans Jahnke bequest to the Zurich James Joyce Foundation, the latest acquisition of Joycean material, particularly testifies to the central role played by the Italian language in both Joyce’s private and literary writings. The focus of this investigation is to highlight two distinct functions of Joyce’s use of Italian in the Zurich documentation. The first part of the essay proposes an overview on Joyce’s correspondence with his son Giorgio, identifying its most important linguistic features. The second part is devoted to the analysis of the manuscript titled “Sulla Spiaggia a Fontana”, a possible self-translation of the poem “On the Beach at Fontana”, which was published in Pomes Penyeach in 1927. Study of the Jahnke collection not only shows how Joyce’s linguistic creativity varies its shapes according to different languages, but also reveals new aspects of the migrant’s perspective on his cosmopolitan reality.

description: The introduction to the monographic section Italy-Ireland: Cultural Inter-Relations, gives a brief account of how this part of the journal tries to fill a gap in transcultural studies by investigating the hitherto relatively underexplored relationship of Ireland with Italy. The editors argue that the topic deserves special attention because throughout the centuries, owing to a shared religion and Ireland’s colonial and postcolonial status, a special relationship was established. Without neglecting the many contributions published on this topic over the past thirty years, the papers collected in this first issue of SIJIS offer an overall view of the relations between Italy and Ireland from the Middle Ages to the present day demonstrating this special relationship. The opening essay, drawing an ample and interdisciplinary panorama of the representations of Ireland in Italy over the centuries, and  the concluding one, introducing new issues and suggestions for further investigations, frame seven papers organized thematically in subsections.  The translation studies section highlights some specific problems presented to the translator because of the Irish nature of the translated texts. Exploration of the links between some major figures and Italy opens up new perspectives even regarding much studied figures such as Joyce while  the time-honoured comparative method of studying influences yields ground-breaking insights as in the study of links between Commedia dell’Arte and Clarke or Mahon and Pasolini. Representations of Italy and  the presence of Italian settings and characters acquire  a specific Irish edge in the writings of Synge, Lady Morgan and Edward Maturin especially when both countries were still in search  of their identities.

description: We attempt to measure the proper motions of two magnetars - the soft gamma-ray repeater SGR 1900+14 and the anomalous X-ray pulsar 1E 2259+586 - using two epochs of Chandra observations separated by ~5 yr. We perform extensive tests using these data, archival data, and simulations to verify the accuracy of our measurements and understand their limitations. We find 90% upper limits on the proper motions of 54 mas/yr (SGR 1900+14) and 65 mas/yr (1E 2259+586), with the limits largely determined by the accuracy with which we could register the two epochs of data and by the inherent uncertainties on two-point proper motions. We translate the proper motions limits into limits on the transverse velocity using distances, and find v_perp < 1300 km/s (SGR 1900+14, for a distance of 5 kpc) and v_perp < 930 km/s (1E 2259+586, for a distance of 3 kpc) at 90% confidence; the range of possible distances for these objects makes a wide range of velocities possible, but it seems that the magnetars do not have uniformly high space velocities of > 3000 km/s. Unfortunately, our proper motions also cannot significantly constrain the previously proposed origins of these objects in nearby supernova remnants or star clusters, limited as much by our ignorance of ages as by our proper motions.

description: The current study investigated the presence of different anxiety profiles in schoolchildren in order to understand whether Mathematics and Test Anxiety are a manifestation of a general form of anxiety, or the expression of specific forms of anxiety. Moreover, we also examined the influence of personal protective factors. The results of a latent profile analysis, conducted on 664 children attending grades 3 to 6, clearly identified three different profiles distinguished on the basis of the level of general, test and mathematics anxiety. Protective factors, such as self concept and resilience, were differently related to anxiety: The former was clearly lower when the risk profile was higher, whereas students were able to maintain a certain level of resilience up to an average risk of developing forms of anxiety. The implications of these findings may lead to the development of specific intervention programs aimed at reducing students' anxiety and fostering self concept and resilience.

description: Electron transport characteristics are investigated through some molecular chains attached to two non-superconducting electrodes by the use of Green's function method. Here we do parametric calculations based on the tight-binding formulation to characterize the electron transport through such bridge systems. The transport properties are significantly influenced by (a) the length of the molecular chain and (b) the molecule-to-electrodes coupling strength and here we focus are results in these aspects. In this context we also discuss the steady state current fluctuations, the so-called shot noise, which is a consequence of the quantization of charge and is not directly available through conductance measurements.

Energetics of vertical migration in Chaoborus trivittatus larvae
Creators: name: Swift, Michael Crane
Publisher: name: University of British Columbia

description: One of the recent theories for the adaptive value of vertical migration (McLaren 1963) states that migrants gain an energetic advantage over non-migrants because by alternating between areas of high and low temperatures they are able to partition energy into growth more efficiently than non-migrants. The energetics of the vertical migration of fourth-instar Chaoborus trivittatus larvae in Eunice Lake, British Columbia were studied to identify and quantify this hypothesized energetic advantage. Fourth-instar C. trivittatus larvae undergo a regular, synchronous, diel vertical migration which exposes them tc a wide range of temperature and prey density. Feeding occurs primarily at night, and near the surface. Although all 20oplankton in Eunice Lake are potential prey, Diajgtomus kenai constitutes the majority of fhe biomass in the diet of fourth-instar larvae. In Eunice Lake C. trivittatus larvae grew more slowly than their potential growth rate because of low food availability. Several energetics parameters including carbon assimilation efficiency, the effect of temperature on respiration rate, and the effects of ration size and temperature on larval growth were measured in the laboratory. Carbon assimilation efficiency of both copepods and cladocerans by C. trivittatus is about 68%. Respiration rate increases linearly with temperature over the range 5-25°, although there is a suggestion of a plateau in oxygen consumption ever the temperature range the larvae are exposed to during their migration. Temperature and ration size interact to determine larval growth rate; fluctuating temperatures limited growth regardless of prey density while at 20° prey density limited the growth rate. Empirical data from the field and laboratory were incorporated into a generalized computer simulation model of the energetics of a vertically migrating larva. The model was used to examine the effects of various migration patterns, physical parameters, and biological parameters on larval growth. Analysis of several possible migration strategies showed that, on an energetics basis alone, growth will be maximized by either staying near the surface where there is feed, or by vertically migrating with a physiologically determined periodicity based on individual feeding history. The results of laboratory growth experiments and computer simulations agreed with these two alternative strategies. However, C. trivittatus larvae in Eunice Lake do not follow either of these patterns. No alternative hypothesis to explain their migration pattern is attractive?, and I conclude that it is a relict of previous selection for this pattern in lakes containing diurnal vertebrate predators.

description: We propose a new model for Fast Radio Bursts (FRBs) based on a sudden discharge of a charged young magnetar, caused by the short falling timescale of oppositely charged particles onto the magnetar. In this scenario, curvature radiation is emitted by particles accelerated at relativistic by the strong electric fields produced by the disconnection and the subsequent reconnection of the magnetic field lines, a process triggered by the sudden discharge. We modeled the magnetars as charged neutron stars in the static approximation using the exterior metric by the Reissner-Nordström. We also adopted an electrical charge distribution proportional to the mass-energy density, although our results are not strongly sensitive to the specific star charge distribution, only to the total charge. Our calculations show that the discharge and emission timescales are several milliseconds, compatible with the FRB phenomena for magnetars with a total charge of $\sim 10^{20}~\mathrm{C}$ and mass and radius in the range of 1.5 to 3.0 $\mathrm{M_{\odot}}$ and 10 to 45 km, respectively. Furthermore, the calculated total emitted power of a coherent pulse is $P_{tot}\sim 10^{42-43} erg/s$, and the frequency range and time scale are also consistent with FRBs astronomical observations. Finally, if the magnetar does not collapse after the discharge, the existence of FRB repeater sources can not rule out the existence of a blast repetition after the time needed to magnetosphere recharges and produce a new discharge.

description: As online news increasingly include data journalism, there is a corresponding increase in the incorporation of visualization in article thumbnail images. However, little research exists on the design rationale for visualization thumbnails, such as resizing, cropping, simplifying, and embellishing charts that appear within the body of the associated article. Therefore, in this paper we aim to understand these design choices and determine what makes a visualization thumbnail inviting and interpretable. To this end, we first survey visualization thumbnails collected online and discuss visualization thumbnail practices with data journalists and news graphics designers. Based on the survey and discussion results, we then define a design space for visualization thumbnails and conduct a user study with four types of visualization thumbnails derived from the design space. The study results indicate that different chart components play different roles in attracting reader attention and enhancing reader understandability of the visualization thumbnails. We also find various thumbnail design strategies for effectively combining the charts' components, such as a data summary with highlights and data labels, and a visual legend with text labels and Human Recognizable Objects (HROs), into thumbnails. Ultimately, we distill our findings into design implications that allow effective visualization thumbnail designs for data-rich news articles. Our work can thus be seen as a first step toward providing structured guidance on how to design compelling thumbnails for data stories.

description: L’objectif de cet article est d’étudier le rôle du trait de personnalité dans la perception de la qualité des soins à travers l’interaction consommateur-consommateur des usagers des hôpitaux publics de Côte d’Ivoire. Pour atteindre cet objectif de recherche, nous avons mis en œuvre une méthodologie quantitative. Elle a permis de recueillir des données auprès 559 usagers durant les mois de Juin et Août 2022 à l’aide d’un questionnaire. Le traitement des données a été fait en utilisant la modélisation par équations structurelles. Les résultats obtenus révèlent que l’introversion/extraversion des traits de personnalité modère significative et positivement contrairement au névrosisme qui modère négativement cette relation entre l’interaction consommateur-consommateur et la qualité des soins.

description: Resonance Energy Transfer manifests in photosynthesis is an extremely efficient energy transferring process, which has attracted many applications such as artificial light harvesting and sensing bio-proteins and measuring nano meter distances accurately. However, the aspects of this transfer when it occurs in the coherent regime are yet to be fully identified. This thesis studies the coherent resonance energy transfer dynamics in various bath coupling regimes in various perturbed quantum environments. Results of the study delineate the effects of these perturbations to overall energy transfer dynamics which could increase and decrease the observed quantum coherence of a quantum system.

description: We propose a large-area, cost-effective Muon Telescope Detector (MTD) for the Solenoidal Tracker at RHIC (STAR) at mid-rapidity and for the next generation of detectors at a possible electron-ion collider. We utilize Multi-gap Resistive Plate Chambers with large modules and long readout strips (Long-MRPC) in the detector design. The results from cosmic ray and beam tests show the intrinsic timing and spatial resolution for a Long-MRPC are 60-70 ps and $\sim1$ cm, respectively. The prototype performance of such a novel muon telescope detector at STAR indicates that muon identification at the transverse momentum of a few GeV/$c$ can be achieved through the combined information of track matching with the MTD, ionization energy loss in the Time Projection Chamber, and time-of-flight measurements. A primary muon over secondary muon ratio of better than 1/3 can be achieved. This provides a promising device for future quarkonium programs and primordial dilepton measurements at RHIC. Simulations of the muon efficiency, the signal-to-background ratio of $J/ψ$, the separation of $Υ$ 1S from 2S+3S states, and the electron-muon correlation from charm pair production in the RHIC environment are presented.
