title: Credit Card Usage and Knowledge in Thailand
Creators: name: Sangsutisearee, Wanna
Publisher: name: Utah State University
Year: 1993

description: This study was conducted to determine the relationship between the characteristics of credit card holders and the extent of credit card usage, the level of credit card knowledge, and the consumer's choice perspectives. The characteristics of credit card holders studied were (a) gender, (b) age, (c) marital status, (d) education, (e) income, and (f) occupation.
Data for this study were collected in Bangkok, Thailand by telephone interviews during July- August 1993. The sample consisted of 150 Bangkok Bank credit card holders. Chi-square and Cramer's V were used to analyze the hypotheses. For all statistical analyses the level of significance was set at .05.
As a result of the 18 specific null hypothesis tests, only two independent variables were found to have a statistically significant relationship with the extent of credit card usage. The findings suggested a positive relationship between the extent of credit card usage and occupation and income. Respondents with higher occupational status and income tended to use credit cards to a greater extent than those with lower occupational status and income. Gender, age, marital status, and education were not related to the extent of credit card usage in this study.
No significant differences were found among the demographic characteristics of credit card holders and the level of credit card knowledge, and consumer's choice perspectives. Gender, age, marital status. education, occupation, and income were not related to the level of credit card knowledge and the consumer's choice.
The results revealed that most Thai credit card holders were not knowledgeable about credit card terms. They were clearly influenced by environmental stimuli, and the effects of society and group norms when they applied for a credit card. They generally chose a card with incomplete information about the alternatives.

description: Selection in a time-periodic environment is modeled via the two-player replicator dynamics. For sufficiently fast environmental changes, this is reduced to a multi-player replicator dynamics in a constant environment. The two-player terms correspond to the time-averaged payoffs, while the three and four-player terms arise from the adaptation of the morphs to their varying environment. Such multi-player (adaptive) terms can induce a stable polymorphism. The establishment of the polymorphism in partnership games [genetic selection] is accompanied by decreasing mean fitness of the population.

description: The Simpson's formula is obtained by approximating the integral of a function on some interval by the integral of the quadratic polynomial determined by the function. However, a multidimensional analogue of the formula has not been given as far as we know. In this paper such a formula is given. Our formula is simple and beautiful, so it may be convenient in Mathematics or Mathematical Physics.

title: Parenting Style and Child Behavior Problems: A Longitudinal Analysis
Creators: name: Young, Margaret H.
Publisher: name: Utah State University
Year: 1993

description: Data from the National Survey of Children were used to study the relationships between children's perceptions of parental support and control and measures of self-esteem and behavior problems over time. Data were collected in 1976, when the children were aged 7-11; 1981, when the children were in their early to mid teens (age 12 to 16); and 1987, when the children were in their late teens and early 20s (age 17 to 22). Parenting measures, based on children's reports, were developed for each wave from items included in the data; constructed variables measuring self -esteem and internal and external expressions of behavior problems were also comprised of individual items drawn from each wave of data. Preliminary analyses showed that parental support was positively correlated to children's self-esteem and negatively related to behavior problems. Although the parental control measures had little effect on the outcome variables, the effect that was present showed that parental coerciveness, rejection, and permissiveness were negatively correlated with children's self-esteem, while being positively associated with both internal and external behavior problems. The preliminary results also showed that the parental effects of mothers and fathers differed for daughters and sons. LISREL analyses were done in an effort to more fully investigate the interactive effects between the constructed variables of interest. Generally, the measures were related as expected, although the relationships were not as strong as anticipated. Of the parenting measures, parental support showed the strongest effects on child outcomes; parental control measures had very little effect on children's self-esteem or behavior problems. In 1987, parenting style had virtually no effect on youths' self-esteem or on behavior problems. For this wave, self-esteem was the strongest predictor of behavior problems in young adults.

description: We present a Lie algebraic approach to a Hamiltonian class covering driven, parametric quantum harmonic oscillators where the parameter set -- mass, frequency, driving strength, and parametric pumping -- is time-dependent. Our unitary-transformation-based approach provides a solution to our general quadratic time-dependent quantum harmonic model. As an example, we show an analytic solution to the periodically driven quantum harmonic oscillator without the rotating wave approximation; it works for any given detuning and coupling strength regime. For the sake of validation, we provide an analytic solution to the historical Caldirola--Kanai quantum harmonic oscillator and show that there exists a unitary transformation within our framework that takes a generalized version of it onto the Paul trap Hamiltonian. In addition, we show how our approach provides the dynamics of generalized models whose Schrödinger equation becomes numerically unstable in the laboratory frame.

description: We discuss the connection between information and copula theories by showing that a copula can be employed to decompose the information content of a multivariate distribution into marginal and dependence components, with the latter quantified by the mutual information. We define the information excess as a measure of deviation from a maximum entropy distribution. The idea of marginal invariant dependence measures is also discussed and used to show that empirical linear correlation underestimates the amplitude of the actual correlation in the case of non-Gaussian marginals. The mutual information is shown to provide an upper bound for the asymptotic empirical log-likelihood of a copula. An analytical expression for the information excess of T-copulas is provided, allowing for simple model identification within this family. We illustrate the framework in a financial data set.

description: The configurational entropy of supercooled liquids extrapolates to zero at the Kauzmann temperature, causing a crisis called the Kauzmann paradox. Here, using a class of multicomponent lattice glass models, we study a resolution of the paradox characterized by a sudden but smooth turn in the entropy as temperature goes sufficiently low. A scalar variant of the models reproduces the Kauzmann paradox with thermodynamic properties at very low temperatures dominated by correlations. An exactly solvable vector variant without correlation illustrates that a sudden entropy turn occurs when discrete local excitations are largely suppressed. Despite being disordered and infinitely degenerate, the ground states have zero entropy per particle.

description: Wasps of the genus Vespula are social insects that have become major pests and predators in their introduced range. Viruses present in these wasps have been studied in the context of spillover from honey bees, yet we lack an understanding of the endogenous virome of wasps as potential reservoirs of novel emerging infectious diseases. We describe the characterization of 68 novel and nine previously identified virus sequences found in transcriptomes of Vespula vulgaris in colonies sampled from their native range (Belgium) and an invasive range (New Zealand). Many viruses present in the samples were from the Picorna-like virus family (38%). We identified one Luteo-like virus, Vespula vulgaris Luteo-like virus 1, present in the three life stages examined in all colonies from both locations, suggesting this virus is a highly prevalent and persistent infection in wasp colonies. Additionally, we identified a novel Iflavirus with similarity to a recently identified Moku virus, a known wasp and honey bee pathogen. Experimental infection of honey bees with this novel Vespula vulgaris Moku-like virus resulted in an active infection. The high viral diversity present in these invasive wasps is a likely indication that their polyphagous diet is a rich source of viral infections.

description: Stimulated emission of photons from a large number of atoms into the mode of a strong light field is the principle mechanism for lasing in "classical" lasers. The onset of lasing is marked by a threshold which can be characterised by a sharp increase in photon flux as a function of external pumping strength. The same is not necessarily true for the fundamental building block of a laser: a single trapped atom interacting with a single optical radiation mode. It has been shown that such a "quantum" laser can exhibit thresholdless lasing in the regime of strong coupling between atom and radiation field. However, although theoretically predicted, a threshold at the single-atom level could not be experimentally observed so far. Here, we demonstrate and characterise a single-atom laser with and without threshold behaviour by changing the strength of atom-light field coupling. We observe the establishment of a laser threshold through the accumulation of photons in the optical mode even for a mean photon number substantially lower than for the classical case. Furthermore, self-quenching occurs for very strong external pumping and constitutes an intrinsic limitation of single-atom lasers. Moreover, we find that the statistical properties of the emitted light can be adjusted for weak external pumping, from the quantum to the classical domain. Our observations mark an important step towards fundamental understanding of laser operation in the few-atom limit including systems based on semiconductor quantum dots or molecules.

description: We demonstrate that Cherenkov radiation can be manipulated in terms of operation frequency, bandwidth, and efficiency by simultaneously controlling the properties of drifting electrons and the photonic states supported by their surrounding media. We analytically show that the radiation rate strongly depends on the momentum of the excited photonic state, in terms of magnitude, frequency dispersion, and its variation versus the properties of the drifting carriers. This approach is applied to design and realize miniaturized, broadband, tunable, and efficient terahertz and far-infrared sources by manipulating and boosting the coupling between drifting electrons and engineered hyperbolic modes in graphene-based nanostructures. The broadband, dispersive, and confined nature of hyperbolic modes relax momentum matching issues, avoid using electron beams, and drastically enhance the radiation rate - allowing that over 90% of drifting electrons emit photons. Our findings open a new paradigm for the development of solid-state terahertz and infrared sources.

description: Context: Although software development is a human activity, Software Engineering (SE) research has focused mostly on processes and tools, making human factors underrepresented. This kind of research may be improved using knowledge from human-focused disciplines. An example of missed opportunities is how SE employs psychometric instruments. Objective: Provide an overview of psychometric instruments in SE research regarding personality and provide recommendations for adopting them. Method: We conducted a systematic mapping to build an overview of instruments used within SE for assessing personality and reviewed their use from a multidisciplinary perspective of SE and social science. Results: We contribute with a secondary study covering fifty years of research (1970 to 2020). One of the most adopted instruments (MBTI) faces criticism within social sciences, and we identified discrepancies between its application and existing recommendations. We emphasize that several instruments refer to the Five-Factor Model, which despite its relevance in social sciences, has no specific advice for its application within SE. We discuss general advice for its proper application. Conclusion: The findings show that the adoption of psychometric instruments regarding personality in SE needs to be improved, ideally with the support of social science researchers. We believe that the review presented in this study can help to understand limitations and to evolve in this direction.

description: We demonstrate a methodology for computationally investigating the mechanical response of a pure molten lead surface system to the lateral mechanical cyclic loads and try to answer the question: how dose the dynamically driven liquid surface system follow the classical physics of the elastic-driven oscillation? The steady-state oscillation of the dynamic surface tension under cyclic load, including the excitation of high frequency vibration mode at different driving frequencies and amplitudes, was compared with the classical theory of single-body driven damped oscillator. Under the highest studied frequency (50 GHz) and amplitude (5%) of the load, the increase of the (mean value) dynamic surface tension could reach ~5%. The peak and trough values of the instantaneous dynamic surface tension could reach (up to) 40% increase and (up to) 20% decrease compared to the equilibrium surface tension, respectively. The extracted generalized natural frequencies and the generalized damping constants seem to be intimately related to the intrinsic timescales of the atomic temporal-spatial correlation functions of the liquids both in the bulk region and in the outermost surface layers. These insights uncovered could be helpful for quantitative manipulation of the liquid surface tension using ultrafast shockwaves or laser pulses.

(2) They cast doubt on Hawking's prediction of black-hole evaporation. (3) They point at various inconsistencies of the black-hole paradigm, in favour of nuclear-burning central engines of AGN. (4) They re-interpret (a best case of) `anomalous redshifts' as non-cosmological, kinematic redshifts in strong jet sources.

description: In this paper, we perform a comprehensive study for the physical properties of SN 2018gk which is a luminous type IIb supernova (SN). We find that the early-time photospheric velocity vary from a larger value to a smaller value before the photosphere reach a temperature floor. We generalize the photosphere modulus and fit the multi-band light curves (LCs) of SN 2018gk. We find that the $^{56}$Ni mass model require $\sim0.90$ M$_\odot$ of $^{56}$Ni which is larger than the derived ejecta mass ($\sim0.10$ M$_\odot$). Alternatively, we use the magnetar plus $^{56}$Ni and the fallback plus $^{56}$Ni models to fit the LCs of SN 2018gk, finding that the two models can fit the LCs. We favor the magnetar plus $^{56}$Ni since the parameters are rather reasonable ($M_{\rm ej} =1.65$ M$_\odot$, $M_{\rm Ni}=0.05$ M$_\odot$ which is smaller than the upper limit of the value of the $^{56}$Ni mass can by synthesized by the neutrino-powered core collapse SNe $B=6.52\times10^{14}$ G which is comparable to those of luminous and superluminous SNe studied in the literature, and $P_0=10.42$ ms which is comparable to those of luminous SNe), while the validity of the fallback plus $^{56}$Ni model depends on the accretion efficiency ($η$). Therefore, we suggest that SN 2018gk might be a SN IIb mainly powered by a central engine. Finally, we confirm the NIR excesses of the spectral energy distributions (SEDs) of SN 2018gk at some epochs and constrain the physical properties of the putative dust using the blackbody plus dust emission model.

An ecological approach to problems of Dark Energy, Dark Matter, MOND and Neutrinos

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Modern astronomical data on galaxy and cosmological scales have revealed powerfully the existence of certain dark sectors of fundamental physics, i.e., existence of particles and fields outside the standard models and inaccessible by current experiments. Various approaches are taken to modify/extend the standard models. Generic theories introduce multiple de-coupled fields A, B, C, each responsible for the effects of DM (cold supersymmetric particles), DE (Dark Energy) effect, and MG (Modified Gravity) effect respectively. Some theories use adopt vanilla combinations like AB, BC, or CA, and assume A, B, C belong to decoupled sectors of physics. MOND-like MG and Cold DM are often taken as opposite frameworks, e.g. in the debate around the Bullet Cluster. Here we argue that these ad hoc divisions of sectors miss important clues from the data. The data actually suggest that the physics of all dark sectors is likely linked together by a self-interacting oscillating field, which governs a chameleon-like dark fluid, appearing as DM, DE and MG in different settings. It is timely to consider an interdisciplinary approach across all semantic boundaries of dark sectors, treating the dark stress as one identity, hence accounts for several "coincidences" naturally.

Fingerprinting and Analysis of Bluetooth Devices with Automata Learning

description: Automata learning is a technique to automatically infer behavioral models of black-box systems. Today's learning algorithms enable the deduction of models that describe complex system properties, e.g., timed or stochastic behavior. Despite recent improvements in the scalability of learning algorithms, their practical applicability is still an open issue. Little work exists that actually learns models of physical black-box systems. To fill this gap in the literature, we present a case study on applying automata learning on the Bluetooth Low Energy (BLE) protocol. It shows that not only the size of the system limits the applicability of automata learning. Also, the interaction with the system under learning creates a major bottleneck that is rarely discussed. In this article, we propose a general automata learning architecture for learning a behavioral model of the BLE protocol implemented by a physical device. With this framework, we can successfully learn the behavior of six investigated BLE devices. Furthermore, we extended the learning technique to learn security critical behavior, e.g., key-exchange procedures for encrypted communication. The learned models depict several behavioral differences and inconsistencies to the BLE specification. This shows that automata learning can be used for fingerprinting black-box devices, i.e., characterizing systems via their specific learned models. Moreover, learning revealed a crashing scenario for one device.

description: Since the early sixteenth century, the bassoon has played a role of varying importance in musical organizations. Early groups used as many as twenty-four bassoons in conjunction with other instruments. Today, it is common to have no more than two or three bassoons in bands and orchestras because other instruments, as they developed, have replaced the bassoon in the instrumentation of such groups. Although the bassoon is not as important numerically as it formerly was, its place in musical organizations is assured because it has expressive colors and tonal qualities which cannot be duplicated by any other instrument. The bassoon is especially important as a bass instrument in small ensembles.

description: The junior college athletic program at College of Southern Utah commenced in 1923. The facilities were barely satisfactory, and the construction of better facilities began in 1926. A new gymnasium was constructed and was rated as one of the better facilities in the state. The football stadium was relocated in 1928 and constructed almost entirely by donated labor , materials and equipment from community residents. A new and larger gymnasium was constructed in 1949.
Football was inaugrated in 1928 on a full-time basis and has maintained this status, except during World War II The College of Southern Utah won the league championship only once and never did go through a season undefeated.
Basketball was always the big s port, having its beginning in 1923. The basketball teams won the league title for many years and went on to higher honors by winning the intermountain championship and participating in the Western States Tournaments. On one occasion, a basketball team entered the National Junior College Tournament and placed sixth.
Wrestling was tried on several occasions, but it failed to take hold and was not permanent until 1959. This team won the league championship.
Baseball was sporadic because of the unpredictable spring weather, and did not become a strong program until 1950. The team of 1963 finished in third place in the National Junior College Tournament.
Track and field had little success until 1946. The teams from 1946 to 1951 did not lose a dual meet and won the conference championship each year, a league record.
Tennis was a hit and miss sport and never did obtain a full schedule.
Eleven men have served as head coach at College of Southern Utah with the first six serving alone and handling all the coaching duties. The coaching duties were split and two coaches were hired in 1946, one for football and one for basketball. This policy has remained constant since then.

description: We present a search for associated production of the standard model (SM) Higgs boson and a $Z$ boson where the $Z$ boson decays to two leptons and the Higgs decays to a pair of $b$ quarks in $p\bar{p}$ collisions at the Fermilab Tevatron. We use event probabilities based on SM matrix elements to construct a likelihood function of the Higgs content of the data sample. In a CDF data sample corresponding to an integrated luminosity of 2.7 fb$^{-1}$ we see no evidence of a Higgs boson with a mass between 100 GeV$/c^2$ and 150 GeV$/c^2$. We set 95% confidence level (C.L.) upper limits on the cross-section for $ZH$ production as a function of the Higgs boson mass $m_H$; the limit is 8.2 times the SM prediction at $m_H = 115$ GeV$/c^2$.

description: Causal dynamical triangulations (CDT) can be used as a regularization of quantum gravity. In two dimensions the theory can be solved anlytically, even before the cut-off is removed and one can study in detail how to take the continuum limit. We show how the CDT theory is related to Euclidean 2d quantum gravity (Liouville quantum gravity), how it can be generalized and how this generalized CDT model has a string field theory representation as well as a matrix model representationof a new kind, and finally how it examplifies the possibility that time in quantum gravity might be the stochastic time related to the branching of space into baby universes.

description: We present visual classifications of merger-induced tidal disturbances in 143 $\rm{M}_* \sim 10^{11}\rm{M}_\odot$ post-starburst galaxies at z$\sim$0.7 identified in the SQuIGG$\vec{L}$E Sample. This sample spectroscopically selects galaxies from the Sloan Digital Sky Survey that have stopped their primary epoch of star formation within the past $\sim$500 Myrs. Visual classifications are performed on Hyper Suprime Cam (HSC) i-band imaging. We compare to a control sample of mass- and redshift-matched star-forming and quiescent galaxies from the Large Early Galaxy Census and find that post-starburst galaxies are more likely to be classified as disturbed than either category. This corresponds to a factor of $3.6^{+2.9}_{-1.3}$ times the disturbance rate of older quiescent galaxies and $2.1^{+1.9}_{-.73}$ times the disturbance rate of star-forming galaxies. Assuming tidal features persist for $\lesssim500$ Myr, this suggests merging is coincident with quenching in a significant fraction of these post-starbursts. Galaxies with tidal disturbances are younger on average than undisturbed post-starburst galaxies in our sample, suggesting tidal features from a major merger may have faded over time. This may be exacerbated by the fact that, on average, the undisturbed subset is fainter, rendering low surface brightness tidal features harder to identify. However, the presence of ten young ($\lesssim150$ Myr since quenching) undisturbed galaxies suggests that major mergers are not the only fast physical mechanism that shut down the primary epoch of star formation in massive galaxies at intermediate redshift.

description: Half-metals are ferromagnets hosting spin-polarized conducting carriers and crucial for spintronics applications. The chromium spinel HgCr2Se4 represents a unique type of half-metal, which features a half-metal to semiconductor transition (HMST) and exhibits colossal magnetoresistance (CMR) across the ferromagnetic-paramagnetic (FM-PM) transition. Using angle-resolved photoemission spectroscopy (ARPES), we find that the Fermi surface of n-type HgCr2Se4 (n-HgCr2Se4) consists of a single electron pocket which moves above the Fermi level (EF) upon the FM-PM transition, leading to the HMST. Such a Lifshitz transition manifests a giant band splitting which originates from the exchange interaction unveiled with a specific chemical nonstoichiometry. The exchange band splitting and the chemical nonstoichiometry are two key ingredients to the HMST and CMR, consistent with our ab-initio calculation. Our findings provide spectroscopic evidences of the electronic origin of the anomalous properties of HgCr2Se4, which address the unique phase transition in half-metals.

description: We use the state-of-the-arts density-functional-theory method to study various magnetic orders and their effects on the electronic structures of the FeSe. Our calculated results show that, for the spins of the single Fe layer, the striped antiferromagnetic orders with distortion are more favorable in total energy than the checkerboard antiferromagnetic orders with tetragonal symmetry, which is consistent with known experimental data, and the inter-layer magnetic interaction is very weak. We investigate the electronic structures and magnetic property of the distorted phases. We also present our calculated spin coupling constants and discuss the reduction of the Fe magnetic moment by quantum many-body effects. These results are useful to understand the structural, magnetic, and electronic properties of FeSe, and may have some helpful implications to other FeAs-based materials.
title: A History of Intercollegiate Wrestling at Utah State University
Creators: name: McCrary, Delwin W.
Publisher: name: Utah State University
Year: 1967

description: This study presents a historical account of intercollegiate wrestling at Utah State University, from its introduction into the athletic program in 1921 until the school year of 1966. Data were gathered by use of historical research methods and personal interviews.
The intercollegiate wrestling program at Utah State University has shown steady growth and development since its introduction in 1922. The primary motivating force behind the wrestling program was George "Doc" Nelson.
The expanding of all phases of collegiate athletics has necessitated a more complex program. Wrestling at U.S.U. has followed this national trend in program development and has in the past two years gained national recognition.
Teachers' attitudes towards the application of merit pay programs in British Columbia

description: Eight years ago the members of the British Columbia Schools Trustees' Association recommended to the teaching profession in British Columbia that they give serious consideration to the proposition of including merit as one of the factors in the determination of their salaries. The British Columbia Teachers' Federation, representing the teaching profession in the province, was vigorous in its opposition to merit pay schedules. The purpose of the present study is to assess the attitudes of the rank and file in the profession, as opposed to the institutional stand of the Teachers' Federation towards this issue. A study of the existing salary structures for teachers in the province showed that the teachers were paid primarily on the basis of their training and experience. An examination of the literature on merit rating pointed out that the training and experience of a teacher could not be equated with his teaching performance, as the research studies conducted indicated very low correlationships between them. The first part of the study, therefore, concluded that the teachers in British Columbia are not being paid on the basis of their teaching experience. The attitudes of the teachers towards this issue of pay based on teaching performance were then examined. Responses from 402 teachers from all levels of the teaching profession were fed into an IBM computer and the results analyzed. Slightly less than half of them (48.0%) opposed merit rating, and the rest were either in favor (39.0%) or were uncertain or did not answer (13.0%). The study, however, showed that the opposition to merit pay was greater if this meant that salaries were to be affected by double increments or super-maxima salaries superimposed on the existing salary structure. The opposition would be lesser if the merit of a teacher was being recognized by rewarding him/her with supervisory posts carrying extra allowances, granting study leave or sabbatical leave, and awarding travel grants for approved purposes. The recommendations in the concluding chapter were made on this basis.

description: In this work we establish some results concerning the existence of external light rings in extremal black hole spacetimes through the Newman-Penrose formalism. Specifically, assuming conformal flatness, staticity and the null energy condition, we show that a sufficient condition for the existence of external light rings is $R < 2 K_{G}$, where $R$, the curvature scalar of the spacetime and $K_{G}$, the Gaussian curvature of a spacelike two-surface, are both evaluated at the outermost event horizon, which can be endowed with spherical, hyperbolic or planar geometry. Our results are valid for any metric gravity theory where photons follow null geodesics.

description: Laser-plasma physics has developed rapidly over the past few decades as high-power lasers have become both increasingly powerful and more widely available. Early experimental and numerical research in this field was restricted to single-shot experiments with limited parameter exploration. However, recent technological improvements make it possible to gather an increasing amount of data, both in experiments and simulations. This has sparked interest in using advanced techniques from mathematics, statistics and computer science to deal with, and benefit from, big data. At the same time, sophisticated modeling techniques also provide new ways for researchers to effectively deal with situations in which still only sparse amounts of data are available. This paper aims to present an overview of relevant machine learning methods with focus on applicability to laser-plasma physics, including its important sub-fields of laser-plasma acceleration and inertial confinement fusion.

description: Properties of the four families of recently introduced special functions of two real variables, denoted here by $E^\pm$, and $\cos^\pm$, are studied. The superscripts $^+$ and $^-$ refer to the symmetric and antisymmetric functions respectively. The functions are considered in all details required for their exploitation in Fourier expansions of digital data, sampled on square grids of any density and for general position of the grid in the real plane relative to the lattice defined by the underlying group theory. Quality of continuous interpolation, resulting from the discrete expansions, is studied, exemplified and compared for some model functions.

description: This paper provides a new catalog of orbits and their parameters for a practically complete list of currently known galactic globular clusters (GCs), compiled by Vasiliev (2019) based on the most accurate modern measurements of their velocities and positions. The integration of the orbits of 152 globular clusters for 5 Gyr backward was performed using the new average proper motions obtained from the Gaia EDR3 catalog (Vasiliev and Baumgardt, 2021) and new average distances (Baumgardt and Vasiliev, 2021) in the axisymmetric three-component potential with spherical bulge, disk component, and spherical dark Navarro-Frank-White halo (Bajkova and Bobylev, 2016). The new orbital parameters are compared with the orbital parameters constructed by us earlier (Bajkova and Bobylev, 2021) in the same gravitational potential using proper motions obtained from the Gaia DR2 catalog (Vasiliev, 2019) and with the distances from the Harris catalog (2010).
