description: We present a general theoretical model for the spatio-temporal dynamics of animal contests. Inspired by interactions between physical particles, the model is formulated in terms of effective interaction potentials, which map typical elements of contest behaviour into empirically verifiable rules of contestant motion. This allows us to simulate the observable dynamics of contests in various realistic scenarios, notably in dyadic contests over a localized resource. Assessment strategies previously formulated in game-theoretic models, as well as the effects of fighting costs, can be described as variations in our model’s parameters. Furthermore, the trends of contest duration associated with these assessment strategies can be derived and understood within the model. Detailed description of the contestants’ motion enables the exploration of spatio-temporal properties of asymmetric contests, such as the emergence of chase dynamics. Overall, our framework aims to bridge the growing gap between empirical capabilities and theory in this widespread aspect of animal behaviour.

description: The operation of electric machines is accompanied by losses which are mostly converted to heat. The heat needs to be dissipated from the machine. With a properly dimensioned motor, the arising heat is balanced with dissipated one. After the motor is started at ambient temperature, all functional parts of the machine are gradually warmed until stabilized. Any overloading of the machine leads to stabilization at temperatures higher than expected by the designers. High temperatures in the machine could cause a crash by damaging an insulation. In case of machines with permanent magnets, the temperature affects their magnetic properties and can leads to demagnetization at the Curie temperature. Therefore, the measuring of temperature is so important for verifying the allowed warming of the motor. Contact and noncontact methods could be used for temperature measuring. Thermal warming and temperature distribution in an electric machine can be also determined by theoretical calculations based, for example, on the finite element method. This method is used by a number of computer software such as Ansys. The article deals with generation and propagation of heat in electric motors and with measuring of warming characteristics with a variable value of a load factor for intermittent periodic loading of asynchronous machine. The loading is carried out by the dynamometer. The temperature measurement is implemented by temperature sensors which are located on the stator winding of the asynchronous motor and are in operation for the whole time the motor is loaded.

description: We consider implications of a fourth generation of leptons, allowing for the most general mass patterns for the fourth generation neutrino. We determine the constraints due to the precision electroweak measurements and outline the signatures to search for at the LHC experiments. As a concrete framework to apply these results we consider the minimal walking technicolor (MWTC) model where the matter content, regarding the electroweak quantum numbers, corresponds to a fourth generation.

description: We examine the energy spectrum of a charged particle in the presence of a {\it non-rotating} finite electric dipole. For {\emph{any}} value of the dipole moment $p$ above a certain critical value p_{\mathrm{c}}$ an infinite series of bound states arises of which the energy eigenvalues obey an Efimov-like geometric scaling law with an accumulation point at zero energy. These properties are largely destroyed in a realistic situation when rotations are included. Nevertheless, our analysis of the idealised case is of interest because it may possibly be realised using quantum dots as artificial atoms.

description: Automated language processing is central to the drive to enable facilitated referencing of increasingly available Sanskrit E texts. The first step towards processing Sanskrit text involves the handling of Sanskrit compound words that are an integral part of Sanskrit texts. This firstly necessitates the processing of euphonic conjunctions or sandhis, which are points in words or between words, at which adjacent letters coalesce and transform. The ancient Sanskrit grammarian Panini's codification of the Sanskrit grammar is the accepted authority in the subject. His famed sutras or aphorisms, numbering approximately four thousand, tersely, precisely and comprehensively codify the rules of the grammar, including all the rules pertaining to sandhis. This work presents a fresh new approach to processing sandhis in terms of a computational schema. This new computational model is based on Panini's complex codification of the rules of grammar. The model has simple beginnings and is yet powerful, comprehensive and computationally lean.

description: An isotropic anti-ferromagnetic quantum state on a square lattice is characterized by symmetry arguments only. By construction, this quantum state is the result of an underlying valence bond structure without breaking any symmetry in the lattice or spin spaces. A detailed analysis of the correlations of the quantum state is given (using a mapping to a 2D classical statistical model and methods in field theory like mapping to the non-linear sigma model or bosonization techniques) as well as the results of numerical treatments (regarding exact diagonalization and variational methods). Finally, the physical relevance of the model is motivated. A comparison of the model to known anti-ferromagnetic Mott-Hubbard insulators is given by means of the two-point equal-time correlation function obtained i) numerically from the suggested state and ii) experimentally from neutron scattering on cuprates in the anti-ferromagnetic insulator phase.

description: The FINUDA experiment performed a systematic study of the charged mesonic weak decay channel of $p$-shell $Λ$-hypernuclei. Negatively charged pion spectra from mesonic decay were measured with magnetic analysis for the first time for ${^{7}_ΛLi}$, ${^{9}_ΛBe}$, ${^{11}_ΛB}$ and ${^{15}_ΛN}$. The shape of the $π^{-}$ spectra was interpreted through a comparison with pion distorted wave calculations that take into account the structure of both hypernucleus and daughter nucleus. Branching ratios $Γ_{π^{-}}/Γ_{tot}$ were derived from the measured spectra and converted to $π^{-}$ decay rates $Γ_{π^{-}}$ by means of known or extrapolated total decay widths $Γ_{tot}$ of $p$-shell $Λ$-hypernuclei. Based on these measurements, the spin-parity assignment $1/2^+$ for ${^{7}_ΛLi}$ and $5/2^+$ for ${^{11}_ΛB}$ ground-state are confirmed and a spin-parity $3/2^+$ for ${^{15}_ΛN}$ ground-state is assigned for the first time.

The use of aerial photographs and sub sampling in the identification and assessment of moose ranges in southern British Columbia
Creators: name: Baynes, Raymond Arthur
Publisher: name: University of British Columbia
Year: 2011

description: A random sample of forty high altitude block vertical aerial photographs was drawn from two extensive districts of the south Cariboo region of British Columbia. The five hundred square miles of sample area so obtained was cover-typed through interpretation of the aerial photographs. Both mature and seral forest stages constituting moose habitat were identified primarily through the use of criteria which permitted the recognition of individual tree species and secondarily through the recognition of characteristics peculiar to the aspect of each forest type when viewed as a unit. Stereoscoptic examination permitted delimination of the types on the aerial photographs. Planimetric measurement of these areas followed. Sub—sampling of these areas resulted in the establishment of sixty—four permanent plots. Twelve thousand feet of line-interception transect data were obtained from the plots. Browse species were classified both for amount of available food and for degree of utilization by moose. Availability was largely determined by standards derived from shrub height and D.B.H., while utilization was categorized into four degrees on the basis of the amounts or the previous years twigs that had been removed from the shrub by the browsing of moose. Analysis of the ground shrub and tree layers resulted in distinctive floral compositions being obtained for seven forest types which constitute moose habitat. Characteristic intensities of browse utilization were also evident in each forest type—the more dense, mature forests receiving heavier usage than the open forest stands. Index ratings were established both for the density of available browse and for the degree or utilization of browse in each of the seven forest types, Application of these indices to the areas of each forest type indicated relative food productivity and usage of browse in the two sample districts. With the establishment of the indices, moose ranges in the remainder of the sample district may be assessed solely from aerial photographs thereby eliminating extensive ground survey, Extension of this method to other forest areas will permit similar assessment of moose habitat in these regions, once any new forest types are identified and valuated through limited ground subsampling. Severe browsing of unpalatable species, not generally consumed, indicated overuse of many moose winter ranges. Controlled burning of certain severely overbrowsed ranges and further reductions in the moose population through either-sex seasons are suggested.

description: Symmetric mass generation is a novel mechanism to give gapless fermions a mass gap by non-perturbative interactions without generating any fermion bilinear condensation. The previous studies of symmetric mass generation have been limited to Dirac/Weyl/Majorana fermions with zero Fermi volume in the free fermion limit. In this work, we generalize the concept of symmetric mass generation to Fermi liquid with a finite Fermi volume and discuss how to gap out the Fermi surfaces by interactions without breaking the U(1) loop group symmetry or developing topological orders. We provide examples of Fermi surface symmetric mass generation in both (1+1)D and (2+1)D Fermi liquid systems when several Fermi surfaces together cancel the Fermi surface anomaly. However, the U(1) loop group symmetry in these cases is still restrictive enough to rule out all possible fermion bilinear gapping terms, such that a non-perturbative interaction mechanism is the only way to gap out the Fermi surfaces. This symmetric Fermi surface reconstruction is in contrast to the conventional symmetry-breaking mechanism to gap the Fermi surfaces. As a side product, our model provides a pristine 1D lattice regularization for the (1+1)D U(1) symmetric chiral fermion model (e.g., the 3-4-5-0 model) by utilizing a lattice translation symmetry as an emergent U(1) symmetry at low energy. This opens up the opportunity for efficient numerical simulations of chiral fermions in their own dimensions without introducing mirror fermions under the domain wall fermion construction.

description: This study presents the implementation of a digital ethnographic project in college-level online Korean language and content courses, inspired by Berti’s (2020) approach to cultural teaching through digital ethnography. The primary aim of this project was to foster critical perspectives among Korean as a Foreign Language (KFL) learners regarding contemporary Korean society, culture, and its people. As part of this initiative, students engaged in the collection and analysis of digital images and photographs. The outcomes of these student projects demonstrated the effectiveness and challenges of digital ethnography as a pedagogical tool. Students from both language and content courses demonstrated varying levels of cultural sensitivity and criticality. Furthermore, this approach encouraged students to develop richer intercultural perspectives encompassing their own culture and that of Korea. This study underscores the potential of digital ethnography as an innovative pedagogical approach in foreign language education, facilitating critical thinking and intercultural competence.

A study of the spark spectra of Indium
Creators: name: Nodwell, Roy Andrew
Publisher: name: University of British Columbia
Year: 2012

description: The spectra of Indium have been photographed from the infra-red to the vacuum ultra-violet on a two metre vacuum spectrograph, a twenty-one foot grating, and a Littrow prism spectrograph. Two sources have been used: an electrodeless discharge and a condensed vacuum spark. Some 1250 Indium lines have been measured in the region 8200 to 237 Angstroms. Oh the basis of these measurements, new energy levels have been found for all spark spectra up to In V. The main extension of analysis has been in In III where we have added thirty-five new terms. The resulting analyses have been critically examined in terms of intermediate coupling theory, which is shown to be satisfactory when perturbations are not present, except in one configuration in In IV in which there are serious departures from theory. Hyperfine structure has been measured in In III and In II, and perturbation calculations have been made which account for observed departures from the Landé interval rule.
Dispersion and collapse in stochastic velocity fields on a cylinder

description: The dynamics of fluid particles on cylindrical manifolds is investigated. The velocity field is obtained by generalizing the isotropic Kraichnan ensemble, and is therefore Gaussian and decorrelated in time. The degree of compressibility is such that when the radius of the cylinder tends to infinity the fluid particles separate in an explosive way. Nevertheless, when the radius is finite the transition probability of the two-particle separation converges to an invariant measure. This behavior is due to the large-scale compressibility generated by the compactification of one dimension of the space.

description: Many complex systems, including networks, are not static but can display strong fluctuations at various time scales. Characterizing the dynamics in complex networks is thus of the utmost importance in the understanding of these networks and of the dynamical processes taking place on them. In this article, we study the example of the US airport network in the time period 1990-2000. We show that even if the statistical distributions of most indicators are stationary, an intense activity takes place at the local (`microscopic') level, with many disappearing/appearing connections (links) between airports. We find that connections have a very broad distribution of lifetimes, and we introduce a set of metrics to characterize the links' dynamics. We observe in particular that the links which disappear have essentially the same properties as the ones which appear, and that links which connect airports with very different traffic are very volatile. Motivated by this empirical study, we propose a model of dynamical networks, inspired from previous studies on firm growth, which reproduces most of the empirical observations both for the stationary statistical distributions and for the dynamical properties.

description: A Josephson junction consisting of an Anderson impurity weakly coupled with two-band and single-band superconductors exposes a time reversal breaking ground state when the coupling between the two bands exceeds a certain threshold. The critical regime occurs around local moment formation. This indicates a fundamental and distinct role of strong correlations: Driving a system into a time reversal breaking ground state. One of the observable consequences is that the impurity magnetization in this phase is reduced.

Time dispersion in quantum electrodynamics

Year: 2022
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: If we use the path integral approach, we can write quantum electrodynamics (QED) in a way that is manifestly relativistic. However the path integrals are confined to paths that are on mass-shell. What happens if we extend QED by computing the path integrals over all paths in energy momentum space, not only those on mass-shell? We use the requirement of covariance to do this in an unambiguous way. This gives a QED where the time/energy components appear in a way that is manifestly parallel to the space/momentum components: we have dispersion in time, entanglement in time, full equivalence of the Heisenberg uncertainty principle (HUP) in time to the HUP in space, and so on. Entanglement in time has the welcome side effect of eliminating the ultraviolet divergences. We recover standard QED in the long time limit. We predict effects at scales of attoseconds. With recent developments in attosecond physics and in quantum computing, these effects should be detectable. Since the predictions are unambiguous and testable the approach is falsifiable. Falsification would sharpen our understanding of the role of time in QED. Confirmation would have significant implications for attosecond physics, quantum computing and communications, and quantum grav

description: We present a learning-enabled Task and Motion Planning (TAMP) algorithm for solving mobile manipulation problems in environments with many articulated and movable obstacles. Our idea is to bias the search procedure of a traditional TAMP planner with a learned plan feasibility predictor. The core of our algorithm is PIGINet, a novel Transformer-based learning method that takes in a task plan, the goal, and the initial state, and predicts the probability of finding motion trajectories associated with the task plan. We integrate PIGINet within a TAMP planner that generates a diverse set of high-level task plans, sorts them by their predicted likelihood of feasibility, and refines them in that order. We evaluate the runtime of our TAMP algorithm on seven families of kitchen rearrangement problems, comparing its performance to that of non-learning baselines. Our experiments show that PIGINet substantially improves planning efficiency, cutting down runtime by 80% on problems with small state spaces and 10%-50% on larger ones, after being trained on only 150-600 problems. Finally, it also achieves zero-shot generalization to problems with unseen object categories thanks to its visual encoding of objects. Project page https://piginet.github.io/.

description: We investigate how uncertainties in flux measurements affect the results from modified blackbody SED fits. We show that an inverse correlation between the dust temperature T and spectral index (beta) naturally arises from least squares fits due to the uncertainties, even for sources with a single T and beta. Fitting SEDs to noisy fluxes solely in the Rayleigh-Jeans regime produces unreliable T and beta estimates. Thus, for long wavelength observations (lambda >~ 200 micron), or for warm sources (T >~ 60 K), it becomes difficult to distinguish sources with different temperatures. We assess the role of noise in recent observational results that indicate an inverse and continuously varying T - beta relation. Though an inverse and continuous T - beta correlation may be a physical property of dust in the ISM, we find that the observed inverse correlation may be primarily due to noise.

Toroidal Super-Heavy Nuclei in Skyrme-Hartree-Fock Approach

description: Within the self-consistent constraint Skyrme-Hartree-Fock+BCS model (SHF+BCS), we found equilibrium toroidal nuclear density distributions in the region of super-heavy elements. For nuclei with a sufficient oblate deformation ($Q_{20}\leq$ -200 b), it becomes energetically favourable to change the genus of nuclear surface from 0 to 1, i.e., to switch the shape from a biconcave disc to a torus. The energy of the toroidal (genus=1) SHF+BCS solution relative to the compact (genus=0) ground state energy is strongly dependent both on the atomic number Z and the mass number A. We discuss the region of Z and A where the toroidal SHF+BCS total energy begins to be a global minimum.

description: This paper presents the design and the realization of a hybrid wireless Gigabit Ethernet indoor communications system operating at 60 GHz. As the 60 GHz radio link operates only in a single-room configuration, an additional Radio over Fiber (RoF) link is used to ensure the communications within all the rooms of a residential environment. The system uses low complexity baseband processing modules. A byte synchronization technique is designed to provide a high value of the preamble detection probability and a very small value of the false detection probability. Conventional RS (255, 239) encoder and decoder are used for channel forward error correction (FEC). The FEC parameters are determined by the tradeoff between higher coding gain and hardware complexity. The results of bit error rate measurements at 875 Mbps are presented for various antennas configurations.

Un gruppo di ricercatori ha utilizzato diversi indici, come l'indice di similarità terrestre e un modello matematico di produttività biologica, per studiare i pianeti attorno alla stella più vicino al Sole: esisterebbero 11 pianeti nella zona abitabile. Due di loro sono in linea o, addirittura, hanno condizioni migliori rispetto alla Terra per la vita fotosintetica.

description: We present heat capacity, electrical and thermal transport measurements of kagome metals $A$V$_3$Sb$_5$ ($A$ = K, Rb, Cs). In all three compounds, development of short-range charge fluctuations above the charge density wave (CDW) transition temperature $T_\mathrm{CDW}$ strongly scatters phonons via electron-phonon coupling, leading to glasslike phonon heat transport, i.e., phonon thermal conductivity decreases weakly upon cooling. Once the long-range charge order sets in below $T_\mathrm{CDW}$, short-range charge fluctuations are quenched, and the typical Umklapp scattering dominated phonon heat transport is recovered. The charge-fluctuations-induced glasslike phonon thermal conductivity implies sizable electron-phonon coupling in $A$V$_3$Sb$_5$.

An inquiry into the usefulness of psychometric techniques in the selection of prison officers
Creators: name: Downey, Richard Harold
Publisher: name: University of British Columbia

description: The purpose of the study was to explore the use of certain psychometric procedures and to study their value in relation to the problems of selection and prediction of prison personnel. The tests selected were the Wesman Personnel Classification Test, the Kuder Preference Record, form CH, the Minnesota Multiphasic Personality Inventory, and the Manson Evaluation. The criterion used to evaluate the tests was supervisors' ratings based on a forced distribution rating scale which measured only one trait, namely job proficiency. The total sample consisted of 100 employed prison officers and all were rated for job proficiency. Sub-samples from the main sample were formed from the extreme ratings of the whole group. Thus, the top 27 per cent represented the successful group and the bottom 27 per cent the unsuccessful group. The tests were analyzed individually. Mean profiles for the total sample were computed for all test variables and were compared with the published norms for each test. Mean scores and standard deviations for both groups of officers were computed and these data were examined for significant differences between the two groups. From an analysis of the mean scores 14 out of 35 test variables significantly discriminated between the two groups. The best predictor proved to be the Social Service scale of the Kuder Preference Record. The next best predictor was Part I (verbal) of the Personnel Classification Test. Biserial correlation coefficients from widespread classes were also computed. These coefficients were generally of a low order, ranging from .04 to .49. Fourteen coefficients were significantly greater than zero. A scattergram analysis of all tests and subtests was also undertaken to determine the best critical scores. This analysis revealed that, for practical purposes, six scales yielded effective cutting scores. The six scales in descending order of effectiveness for selection purposes were Part I, Personnel Classification Test, the Kuder Social Service scale, the MMPI Psychasthenia scale, the MMPI Depression scale, the MMPI Hostility scale, and the Manson Evaluation Total score. In general, the results indicate the psychometric tests have value for the screening of prison officers. However, it is indicated that the results must be employed with caution until a further validation study is carried out on a sample of officers that is more representative of the population upon which it is intended to use the tests, viz., a sample of job applicants.
