description: The excitation of the carbon $2^+$ state at 4.439 MeV by $70-150$ MeV electron impact and its subsequent decay to the ground state by photon emission is described within the distorted-wave Born approximation. The transition densities are obtained from the nuclear quasiparticle phonon model. The photon angular distributions are compared with earlier results and with experiment, including the influence of bremsstrahlung. Predictions for spin asymmetries in the case of polarized electron impact are also made.

Bethe ansatz solution of zero-range process with nonuniform stationary state
Creators: name: Povolotsky, A. M.

Year: 2004
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The eigenfunctions and eigenvalues of the master-equation for zero range process with totally asymmetric dynamics on a ring are found exactly using the Bethe ansatz weighted with the stationary weights of particle configurations. The Bethe ansatz applicability requires the rates of hopping of particles out of a site to be the $q$-numbers $[n]_q$. This is a generalization of the rates of hopping of noninteracting particles equal to the occupation number $n$ of a site of departure. The noninteracting case can be restored in the limit $q\to 1$. The limiting cases of the model for $q=0,\infty$ correspond to the totally asymmetric exclusion process, and the drop-push model respectively. We analyze the partition function of the model and apply the Bethe ansatz to evaluate the generating function of the total distance travelled by particles at large time in the scaling limit. In case of non-zero interaction, $q \ne 1$, the generating function has the universal scaling form specific for the Kardar-Parizi-Zhang universality class.

description: A theory of heterostructures comprised of LaTiO$_3$ (a Mott insulator) and SrTiO$_3$ (a band insulator) is presented. The band structure of the Ti $d$% -electrons is treated with a nearest neighbor tight-binding approximation; the electric fields arising from the La$^{3+}$/Sr$^{2+}$ charge difference and the carriers are treated within a Hartree approximation; and the on-site interactions are treated by unrestricted Hartree-Fock. The phase diagram as a function of interaction strength and layer number is determined and predictions are made for optical conductivity experiments. A note worthy finding is that the edges of the heterostructure are generally metallic.

description: Abstract

This research advances the integration of AI and robotics for autonomous exploration and navigation in dynamic and unstructured environments. Employing an interpretivist philosophy, a deductive approach, and a descriptive design, the study focuses on sensor fusion, SLAM techniques, decision-making algorithms, and platform integration. Through secondary data collection, technical details encompassing Bayesian sensor fusion, CNN-based perception, and Graph SLAM with loop closure detection are explored. Hardware modifications enable seamless AI-robotics integration, with software middleware like ROS facilitating real-time data processing. Rigorous testing and validation in simulated and real-world environments confirm system robustness. The research reveals that advanced perception strategies and SLAM techniques significantly enhance environmental understanding and mapping accuracy. Decision-making algorithms, particularly RL methods, demonstrate adaptability and intelligence in navigation. The integration of AI with the robotic platform showcases the pivotal role of hardware and software harmonization in achieving seamless operation. Recommendations include exploring semantic perception, dynamic obstacle avoidance, and multi-agent collaboration. Future work should focus on deep reinforcement learning, bio-inspired algorithms, and emerging sensor technologies.

description: Employing the density-matrix renormalization group technique in the matrix-product-state representation, we investigate the photoexcited superconducting correlations induced by the $η$-pairing mechanism in the half-filled Hubbard chain. We estimate the characteristic pair correlation function and verify the accuracy of our numerical results by comparison with exact-diagonalization data for small systems. The optimal parameter set of the pump that most enhances the $η$-pair correlations, is calculated in the strong-coupling regime. For such a pump, we explore the possibility of quasi-long-range order.

description: Altermagnetism is a newly discovered magnetic class named after the alternating spin polarizations in both real and reciprocal spaces. Like the spin-splitting of electronic bands, the magnon bands in altermagnets are predicted to exhibit alternating chiral splitting. In this work, by performing inelastic neutron scattering on $α$-MnTe, we directly verified the chiral splitting in altermagnetic magnon dispersions. The lifted degeneracy of chirality is further explained by a symmetric-exchange origin. In addition, the $g$-wave magnetism was identified in MnTe.

description: With the advancement in personal smart devices and pervasive network connectivity, users are no longer passive content consumers, but also contributors in producing new contents. This expansion in live services requires a detailed analysis of broadcasters' and viewers' behavior to maximize users' Quality of Experience (QoE). In this paper, we present a dataset gathered from one of the popular live streaming platforms: Facebook. In this dataset, we stored more than 1,500,000 live stream records collected in June and July 2018. These data include public live videos from all over the world. However, Facebook live API does not offer the possibility to collect online videos with their fine grained data. The API allows to get the general data of a stream, only if we know its ID (identifier). Therefore, using the live map website provided by Facebook and showing the locations of online streams and locations of viewers, we extracted video IDs and different coordinates along with general metadata. Then, having these IDs and using the API, we can collect the fine grained metadata of public videos that might be useful for the research community. We also present several preliminary analyses to describe and identify the patterns of the streams and viewers. Such fine grained details will enable the multimedia community to recreate real-world scenarios particularly for resource allocation, caching, computation, and transcoding in edge networks. Existing datasets do not provide the locations of the viewers, which limits the efforts made to allocate the multimedia resources as close as possible to viewers and to offer better QoE.

description: Surface alloying is shown to produce electronic states with a very large spin-splitting. We discuss the long range ordered bismuth/silver(111) surface alloy where an energy bands separation of up to one eV is achieved. Such strong spin-splitting enables angular resolved photoemission spectroscopy to directly observe the region close to the band edge, where the density of states shows quasi-one dimensional behavior. The associated singularity in the local density of states has been measured by low temperature scanning tunneling spectroscopy. The implications of this new class of materials for potential spintronics applications as well as fundamental issues are discussed.

description: The spatial and temporal discreteness of gravitational wave sources leads to shot noise that may, in some regimes, swamp any attempts at measuring the anisotropy of the gravitational wave background. Cross-correlating a gravitational wave background map with a sufficiently dense galaxy survey can alleviate this issue, and potentially recover some of the underlying properties of the gravitational wave background. We quantify the shot noise level and we explicitly show that cross-correlating the gravitational wave background and a galaxy catalog improves the chances of a first detection of the background anisotropy with a gravitational wave observatory operating in the frequency range (10Hz,100Hz), given sufficient sensitivity.

Our procedure allow a simple treatment for generally covariant noncommutative extended systems and it contains, as a particular case, the thermodynamics and the quantum tensionless string theory. The effect induced by noncommutativity in the field space is to produce a confinement among pairing of null p-branes.

Final Stages of Planet Formation

Year: 2004

description: We address three questions regarding solar system planets. What determined their number? Why are their orbits nearly circular and coplanar? How long did they take to form? Runaway accretion in a disk of small bodies resulted in a tiny fraction of the bodies growing much larger than all the others. This was followed by oligarchic growth during which the big bodies maintained similar masses and uniformly spaced semi-major axes. We depart from standard treatments of planet formation by assuming that as the big bodies got bigger, the small ones got smaller as the result of undergoing a collisional fragmentation cascade. It follows that oligarchy was a brief stage in solar system evolution. When the oligarchs' surface mass density matched that of the small bodies, dynamical friction was no longer able to balance viscous stirring, so their velocity dispersion increased to the extent that their orbits crossed. This marked the end of oligarchy. What happened next differed in the inner and outer parts of the planetary system. In the inner part, where the ratios of the escape velocities from the surfaces of the planets to the escape velocities from their orbits are smaller than unity, big bodies collided and coalesced after their random velocities became comparable to their escape velocities. In the outer part, where these ratios are larger than unity, the random velocities of some of the big bodies continued to rise until they were ejected. In both parts, the number density of the big bodies eventually decreased to the extent that gravitational interactions among them no longer produced large scale chaos. After that their orbital eccentricities and inclinations were damped by dynamical friction from the remaining small bodies. The last and longest stage in planet formation was the clean up of small bodies.

Session-Based Recommender Systems for Action Selection in GUI Test Generation

Year: 2020
Subjects: subject: Software Engineering (cs.SE)
subject: FOS: Computer and information sciences

description: Test generation at the graphical user interface (GUI) level has proven to be an effective method to reveal faults. When doing so, a test generator has to repeatably decide what action to execute given the current state of the system under test (SUT). This problem of action selection usually involves random choice, which is often referred to as monkey testing. Some approaches leverage other techniques to improve the overall effectiveness, but only a few try to create human-like actions---or even entire action sequences. We have built a novel session-based recommender system that can guide test generation. This allows us to mimic past user behavior, reaching states that require complex interactions. We present preliminary results from an empirical study, where we use GitHub as the SUT. These results show that recommender systems appear to be well-suited for action selection, and that the approach can significantly contribute to the improvement of GUI-based test generation.

description: A theorem of Batyrev's asserts that if two nonsingular varieties V,W are birational, and their canonical bundles agree after pull-back to a resolution of indeterminacies of a birational map between them, then the Betti numbers of V and W coincide. We prove that, in the same hypotheses, the total homology Chern classes of V and W are push-forwards of the same class in the Chow group of the resolution. For example, it follows that the push-forward of the total Chern class of a crepant resolution of a singular variety is independent of the resolution.

description: Motivated by the geometrical structures of quantum mechanics, we introduce an almost-complex structure $J$ on the product $M\times M$ of any parallelizable statistical manifold $M$. Then, we use $J$ to extract a pre-symplectic form and a metric-like tensor on $M\times M$ from a divergence function. These tensors may be pulled back to $M$, and we compute them in the case of an N-dimensional symplex with respect to the Kullback-Leibler relative entropy, and in the case of (a suitable unfolding space of) the manifold of faithful density operators with respect to the von Neumann-Umegaki relative entropy.

description: 4D Einstein gravity coupled to scalars and abelian gauge fields in its 2-Killing vector reduction is shown to be quasi-renormalizable to all loop orders at the expense of introducing infinitely many essential couplings. The latter can be combined into one or two functions of the `area radius' associated with the two Killing vectors. The renormalization flow of these couplings is governed by beta functionals expressible in closed form in terms of the (one coupling) beta function of a symmetric space sigma-model. Generically the matter coupled systems are asymptotically safe, that is the flow possesses a non-trivial UV stable fixed point at which the trace anomaly vanishes. The main exception is a minimal coupling of 4D Einstein gravity to massless free scalars, in which case the scalars decouple from gravity at the fixed point.

description: We report on multi-band (UBVRIZJsKs) observations of the host galaxy of the April 18, 2000 gamma-ray burst. The Spectral Energy Distribution (SED) is analysed by fitting empirical and synthetic spectral templates. We find that: (i) the best SED fit is obtained with a starburst template, (ii) the photometric redshift is consistent with the spectroscopic redshift, (iii) the colours of the host are inconsistent with an old stellar population, and (iv) the global extinction is constrained to be in the range Av=0.12-0.61 mag. The derived global extinction agrees with the one reported for the afterglow (Av=0.4-0.9 mag), suggesting a homogeneous distribution of the interstellar medium (ISM) in the host galaxy. These findings are supplemented by morphological information from Hubble Space Telescope (HST) imaging: the surface brightness profile is smooth, symmetric and compact with no underlying structures (like dust lanes, spiral arms or disks). A natural scenario which accounts of all the above results is a nuclear starburst that harbours a young population of stars from which the GRB originated.

description: Over the years, the rising food prices coupled with the prevailing food insecurity in the entire Sub-Saharan Africa region are perceived to be having debilitating effects on nutrition and health outcomes. This paper therefore examines the impact of rising food prices on under-five and infant mortality rates in 31 selected sub-Saharan African countries for the period 2001-2012 using the fixed effects, random effects, difference GMM and the system GMM. The results show that rising food prices exert significant adverse effects on both infant and under-five mortality rates in Sub-Saharan Africa. The paper suggests the need for increased government’s efforts toward increased food supply and urgent nutritional support involving nutrient-rich-food items to the target groups

description: In this study, the objective is to identify consumers’ willingness to consume different foods and the factors that could drive their food preferences. One hundred non-academic staff and students at the University of Alberta in Edmonton, Canada participated in the study. Data were collected using focus group discussions, a survey questionnaire and a contingent valuation exercise. In the focus groups, participants discussed their preferences for traits in livestock and their products, their interest in natural foods and their perceptions regarding naturalness of food in relation to the different types of farming and technologies. In the survey questionnaire, participants were asked about their food consumption habits, perceptions, attitudes and preferences for different foods and technologies, generalized trust in people and trust in groups or institutions responsible for food in Canada among other issues. In the contingent valuation exercise, participants chose the price they were willing to pay for pork with different information about carnosine and omega-3 fatty acids. We find that there is heterogeneity in terms of consumers’ perceptions, attitudes and behaviour regarding natural foods. In summary, the cost of food, concerns about human and environmental impacts and trustworthiness of information on labels are some of the factors that influence participants’ decisions to buy pork labeled as coming from disease resilient or feed efficient pigs or pigs that are higher in a human or animal health component. Although some people accept genetic modification, other participants were concerned about its use in improving disease resilience, feed efficiency and human or animal health component in pigs. Although there are some variations in the results, generalized trust in people, food technology neophobia and concerns about product leanness, country of origin of the product, nutrition content, use of hormones and antibiotics in livestock production and environmental foot print of livestock production are associated with attitudes, perceptions and behaviour regarding natural foods. Participants are willing to pay more for pork chops with more information about carnosine and omega-3 fatty acids as compared to pork chops with less information. In comparison to carnosine, participants are willing to pay more for pork chops with information about omega-3 fatty acids. Generalized trust in people, trust in advocacy groups, natural product interest, frequency of purchasing products with a health claim and knowledge of sodium content in pork that have a health claim are associated with willingness to pay for enhanced carnosine and omega-3 fatty acids in pork.

description: We analyzed high angular resolution 45.5 GHz images of the W49 North massive star forming region obtained in 1998 and 2016 with the Very Large Array. Most of the ultracompact HII regions show no detectable changes over the time interval of the observations. However, subcomponents B1, B2, G2a and G2c have increased its peak flux densities by values in the range of 3.8 to 21.4 \%. Most interestingly, the cometary region C clearly shows proper motions that at the distance of the region are equivalent to a velocity of 76$\pm$6 km s$^{-1}$ in the plane of the sky. We interpret this region as the ionized bowshock produced by a runaway O6 ZAMS star that was ejected from the eastern edge of Welch's ring about 6,400 years ago.

description: The study estimates the rate of technological change in Uganda’s agriculture during 2005-2010, and across the 4 major regions of the country. Using a nationally representative household panel data set, a time trend variable in the stochastic production frontier was used to account for hicksneutral technological change. The frontier is then re-modelled using binary time trend dummy variables to capture the temporal pattern of technological change. Overall it was found that technological progress was small and insignificant of 0.031% but further decomposition at regional level revealed more interesting findings. The western region had technological progress at 0.6%, and the central region had technological regress of 0.57%, both significant at 5% level. The northern region had technological progress at 0.008% and the eastern region had technological regress of 0.11% both insignificant at 5% level. The findings suggest that more public and private investments in region-specific technology development would be required to accelerate technological progress especially in the northern and eastern regions of the country. Alternatively with the existing level of investment, effort should be made to address the institutional issues that constrain efficient dissemination of the technologies developed from the National Agricultural Research System.
From Thermodynamic Sufficiency to Information Causality

description: The principle called information causality has been used to deduce Tsirelson's bound. In this paper we derive information causality from monotonicity of divergence and relate it to more basic principles related to measurements on thermodynamic systems. This principle is more fundamental in the sense that it can be formulated for both unipartite systems and multipartite systems while information causality is only defined for multipartite systems. Thermodynamic sufficiency is a strong condition that put severe restrictions to shape of the state space to an extend that we conjecture that under very weak regularity conditions it can be used to deduce the complex Hilbert space formalism of quantum theory. Since the notion of sufficiency is relevant for all convex optimization problems there are many examples where it does not apply.

description: Trust and perceptions of fairness in markets have been shown to be important in consumer behavior in different contexts. However, there have not been many studies relating the concept of fairness is supply chains to food purchasing behavior. In this study, we explore the relationships between trust, fairness and perception of quality of food produced from three food technologies. The technologies are as follows: (i) bread fortified with omega-3 fatty acids using nanotechnology (ii) pork chops from pigs selectively bred for disease resistance using genomic selection (iii) baby spinach treated with essential oils to reduce concentrations of E. coli O157:H7. Data are from a small exploratory project conducted in 2015 at the University of Alberta, Canada, where 31 non-academic staff participated in stated preference experiments and completed a survey questionnaire. Stated preference data are analysed using conditional logit regressions. Different potential explanatory fairness variables are created using questions from previous studies. From the results, both the constructs associated with trust and with fairness in supply chains have explanatory power. Although there are some variations in results (depending on the type of questions used to measure fairness), fairness positively influences trust in the food supply chain. Future studies might need to consider including perceptions of fairness in supply chains in the analysis of consumer acceptance of novel technologies.

description: This paper presents a novel, more efficient proper orthogonal decomposition (POD) based reduced-order model (ROM) for compressible flows. In this POD model the governing equations, i.e., the conservation of mass, momentum, and energy equations were written using specific volume instead of density. This substitution allowed for the pre-computation of the coefficients of the system of ODEs that make up the reduced-order model. Several methods were employed to enhance the stability of the ODE solver: the penalty method to enforce boundary conditions, artificial dissipation, and a method that modifies the number of modes used in the POD approximation. This new POD-based reduced-order model was validated for four cases at both on- and off-reference conditions: a quasi-one-dimensional nozzle, a two-dimensional channel, a three-dimensional axisymmetric nozzle, and a transonic fan. The speedup obtained by using the POD-based ROM vs. the full-order model exceeded four orders of magnitude in all cases tested.

Theory of Aging in Structural Glasses

description: The random first order transition theory of the dynamics of supercooled liquids is extended to treat aging phenomena in nonequilibrium structural glasses. A reformulation of the idea of ``entropic droplets'' in terms of libraries of local energy landscapes is introduced which treats in a uniform way the supercooled liquid (reproducing earlier results) and glassy regimes. The resulting microscopic theory of aging makes contact with the Nayaranaswamy-Moynihan-Tool nonlinear relaxation formalism and the Hodge-Scherer extrapolation of the Adam-Gibbs formula, but deviations from both approaches are predicted and shown to be consistent with experiment. The nonlinearity of glassy relaxation is shown to quantitatively correlate with liquid fragility. The residual nonArrhenius temperature dependence of relaxation observed in quenched glasses is explained. The broadening of relaxation spectra in the nonequilibrium glass with decreasing temperature is quantitatively predicted. The theory leads to the prediction of spatially fluctuating fictive temperatures in the long-aged glassy state, which have non-Gaussian statistics. This can give rise to ``ultra-slow'' relaxations in systems after deep quenches.
