Analytical solutions for two atoms in a harmonic trap: p-wave interactions
Creators: name: Idziaszek, Zbigniew
Publisher: name: arXiv
Year: 2009
Subjects: subject: Atomic Physics (physics.atom-ph)
subject: FOS: Physical sciences

description: We derive analytical solutions for the system of two ultracold spin-polarized fermions interacting in p wave and confined in an axially symmetric harmonic trap. To this end we utilize p-wave pseudopotential with an energy-dependent scattering volume. This allows to describe the scattering in tight trapping potentials in the presence of scattering resonances. We verify predictions of the pseudopotential treatment for some model interaction potential, obtaining an excellent agreement with exact energy levels. Then we turn to the experimentally relevant case of neutral atom interactions in the vicinity of a p-wave Feshbach resonance. In the framework of the multichannel quantum-defect theory we derive relatively simple formula for an energy-dependent scattering volume, and later we apply it to investigate the energy spectrum of trapped atoms close to the p-wave Feshbach resonance.

description: We study the transformation into a baryon asymmetry of a charge initially stored in a complex (waterfall) scalar field at the end of a hybrid inflation phase as described in Ref[1]. The waterfall field is coupled to right-handed neutrinos, and is also responsible for their Majorana masses. The charge is finally transferred to the leptons of the Standard Model through the decay of the right-handed neutrinos without introducing new CP violating interactions. Other needed processes, like the decay of the inflaton field and the reheating of the Universe are also discussed in detail.

description: The citation impact of Environment and Planning B can be visualized using its citation relations with journals in its environment as the links of a network. The size of the nodes is varied in correspondence to the relative citation impact in this environment. Additionally, one can correct for the effect of within-journal "self"-citations. The network can be partitioned and clustered using algorithms from social network analysis. After transposing the matrix in terms of rows and columns, the citing patterns can be mapped analogously. Citing patterns reflect the activity of the community of authors who publish in the journal, while being cited indicates reception. Environment and Planning B is cited across the interface between the social sciences and the natural sciences, but its authors cite almost exclusively from the domain of the Social Science Citation Index.

description: We propose a dark matter (DM) scenario in an extension of a left-right symmetric model with a gauge-singlet scalar field. The gauge-singlet scalar can automatically become a DM candidate, provided that both P and CP symmetries are only broken spontaneously. Thus no extra discrete symmetries are needed to make the DM candidate stable. After constraining the model parameters from the observed relic DM density we make predictions for direct detection experiments. We show that for some parameter range, the predicted WIMP-nucleon elastic scattering cross section can reach the current experimental upper bound, which can be tested by the experiments in the near future.

Studies of dispersion-hardening parameters

Publisher: name: University of British Columbia
Year: 2011

description: Experiments were carried out with 1 micron copper powder compacts containing up to 7.5 vol % .018 micron alumina, and with various types of lead powder compacts containing up to 20 vol % of various other materials. The results indicate that dispersion-hardened alloys should be divided into three groups on the basis of the nature of the second phase. i) particulate, adherent (not coherent) with matrix ii) particulate, non-adherent with matrix iii) semi-continuous It is suggested that the room temperature strengthening of the second and third groups of alloys may be due primarily to a grain size effect as described by the Hall-Petch relationship. The cell-like structure recently proposed for S.A.P. has been observed in the lead-lead oxide system by electron microscopy. An explanation of the difference in properties between extruded and rolled dispersion-hardened alloys has been offered in terms of the directional deformation caused by rolling.

A self-framing PCM system
Creators: name: Shimokura, Satoru Howard
Publisher: name: University of British Columbia
Year: 2012

description: A single channel pulse code modulation (PCM) speech communication system is described using a binary code with seven digits per code group and a sampling rate of 8000 per second. A unique feature of the system is the pulse group synchronization or framing scheme that is employed to co-ordinate the operations of the coder and the decoder. A method is outlined wherein the system is able to establish correct framing without the use of auxiliary framing digits. The framing information is inherent in the coded signals. The coder operates on the circulating pulse principle and is a modified version of a coder previously described by Hafer. The decoder is basically one of the pulse count type. The received code pulses produce binary amounts of charge which are stored as voltages on a capacitor. The voltage on the capacitor after one cycle of decoder operation is proportional to the amplitude of the original sample taken at the coder. Test results indicate that the performance is adequate for good quality reproduction of speech. The group synchronization scheme performed perfectly and correct framing was achieved in times so short that misframing noise was inaudible. The proposed framing scheme is adaptable to small PCM speech systems where simplicity in the instrumentation and economy in the use of the digits are important.

description: We observe the dynamics of pulse trapping in a microstructured fiber. Few-cycle pulses create a system of two pulses: a Raman shifting soliton traps a pulse in the normal dispersion regime. When the soliton approaches a wavelength of zero group velocity dispersion the Raman shifting abruptly terminates and the trapped pulse is released. In particular, the trap is less than 4ps long and contains a 1ps pulse. After being released, this pulse asymmetrically expands to more than 10ps. Additionally, there is no disturbance of the trapping dynamics at high input pulse energies as the supercontinuum develops further.

description: In this paper we continue our investigation of the analogical neural network, paying interest to its replica symmetric behavior in the absence of external fields of any type. Bridging the neural network to a bipartite spin-glass, we introduce and apply a new interpolation scheme to its free energy that naturally extends the interpolation via cavity fields or stochastic perturbations to these models. As a result we obtain the free energy of the system as a sum rule, which, at least at the replica symmetric level, can be solved exactly. As a next step we study its related self-consistent equations for the order parameters and their rescaled fluctuations, found to diverge on the same critical line of the standard Amit-Gutfreund-Sompolinsky theory.

description: To ascertain if the photopic negative response of the electroretinogram is different in autism spectrum disorder as a potential clinical marker. Visual function can be atypical in autism spectrum disorder and structural imaging of the ganglion cell layers has been reported to differ in these individuals. Therefore, we sought to investigate if the photopic negative response of the full field electroretinograms, a measure of ganglion cell function, could help explain the visual perceptual differences in autism spectrum disorder and support the structural changes observed. Participants (n = 55 autism spectrum disorder, aged 5.4–26.7 years) and control (n = 87, aged 5.4–27.3 years) were recruited for the study. Full-field light-adapted electroretinograms using a Troland protocol with 10 flash strengths from −0.367 to 1.204 log photopic cd.s.m−2 were recorded in each eye. The photopic negative response amplitudes at Tmin and at t = 72 ms were compared between groups along with the a- and b-wave values. There were no significant interactions between groups for the Photopic Negative Response measures of amplitude or time (p > 0.30). There was a group interaction between groups and flash strengths for the b-wave amplitude as previously reported (p The photopic negative response results suggest that there are no significant differences in the summed retinal ganglion cell responses produced by a full-field stimulus.

Subjects: subject: Konferenzschrift
subject: 510

description: Free probability theory is a line of research which parallels aspects of classical probability, in a non-commutative context where tensor products are replaced by free products, and independent random variables are replaced by free random variables. The theory grew out of attempts to solve some longstanding problems about von Neumann algebras of free groups. In the almost twenty years since its creation, free probability has become a subject in its own right, with connections to several other parts of mathematics: operator algebras, the theory of random matrices, classical probability and the theory of large deviations, algebraic combinatorics, topology. Free probability also has connections with applied mathematics (wireless communication) and some mathematical models in theoretical physics. The Oberwolfach workshop on free probability brought together a very strong group of mathematicians representing the current directions of development in the area.

Year: 2005
Subjects: subject: Konferenzschrift
subject: 510

description: The aim of this Arbeitsgemeinschaft was to present the theory of Algebraic Cobordism due to Marc Levine and Fabien Morel through the lines of their original articles: Inspired by the work of Quillen on complex cobordism, one first introduces the notion of oriented cohomology theory on the category of smooth varieties over a field k. Grothendieck’s method allows one to extend the theory of Chern classes to such theories. When char(k) = 0, one proves the existence of a universal oriented cohomology theory X → Ω∗ (X). Localisation and homotopy invariance are then proved for this universal theory. For any field k of characteristic 0 one can prove for algebraic cobordism the analogue of a theorem of Quillen on complex cobordism: the cobordism ring of the ground field is the Lazard ring L and for any smooth k-variety X, the algebraic cobordism ring Ω∗ (X) is generated, as an L-module, by elements of non negative degree. This implies Rost’s conjectured degree formula. One also gives a relation between the Chow ring, the K0 of a smooth k-variety X and Ω∗ (X). The technical construction of pullbacks is the subject of two talks. At the end one presents the state of advances on the conjectural isomorphism between Levine-Morel construction of algebraic cobordism and the ”homotopical algebraic cobordism”, the cohomology theory represented by motivic Thom spectrum in the Morel-Voevodsky A1 -stable homotopy category. The Arbeitsgemeinschaft was organised by Marc Levine(Boston) and Fabien Morel(München). It was well attended with over 40 participants.

On Measuring Accurate 21-cm Line Profiles with the Robert C. Byrd Green Bank Telescope

description: We use observational data to show that 21 cm line profiles measured with the Green Bank Telescope (GBT) are subject to significant inaccuracy. These include ~10% errors in the calibrated gain and significant contribution from distant sidelobes. In addition, there are ~60% variations between the GBT and Leiden/Argentine/Bonn 21 cm line profile intensities, which probably occur because of the high main-beam efficiency of the GBT. Stokes V profiles from the GBT contain inaccuracies that are related to the distant sidelobes. We illustrate these problems, define physically motivated components for the sidelobes, and provide numerical results showing the inaccuracies. We provide a correction scheme for Stokes I 21 cm line profiles that is fairly successful and provide some rule-of-thumb comments concerning the accuracy of Stokes V profiles.

Equitable Compensation for Distress in Commercial Contexts

Publisher: name: Monash University
Year: 2025
Subjects: classificationCode: 480602
subject: Equity and trusts law

description: Despite equity’s longstanding jurisdiction to grant compensation for breaches of equitable obligations, there has been limited analysis of whether that jurisdiction extends to purely personal interests. In two relatively recent breach of confidence cases, Australian courts have awarded equitable compensation for distress. Drawing on those cases, this article seeks to challenge the traditional view that equitable compensation can only vindicate financial losses. It takes the example of ethical investment funds and considers the scenario where the trustees of those funds make profit-generating but unethical investments. It argues that in those circumstances, it would be doctrinally sound to award equitable compensation to beneficiaries who have suffered distress as a result of the unethical investments. That conclusion is arrived at by considering the principles underlying equity’s inherent jurisdiction to award equitable compensation for breaches of general equitable obligations. Based on an inductive approach to earlier cases, the article suggests that equity may award compensation wherever the affected interest is the subject matter of the equitable obligation said to have been breached, regardless of whether that interest is financial in nature.
A survey of low-noise nucleonic amplifiers
Creators: name: Heywood, Donald Robert
Publisher: name: University of British Columbia
Year: 2011

description: In nucleonic energy determinations, pulses from capacitive sources must be amplified with the addition of a minimum amount of noise. The problems encountered in this were considered both theoretically and experimentally. The "classical" theory of Gillespie for systems using ion chambers and tube amplifiers is generalized to include systems using the modern solid-state detectors and amplifiers. Expressions are found relating the "equivalent input noise charge" to the characteristics of the detector, the preamplifier, and the pulse-shaping network. A relationship is derived between the equiv-noise charge and the conventional noise figure of an amplifier. It shows that amplifiers suitable for nucleonic work have noise figures much lower than 1 db. The theoretical study shows that conventional vacuum tubes, Nuvistors, and field effect transistors are the best active devices for this application. Junction transistors, tunnel diodes, para-metric amplifiers and Masers are shown to be unsuitable. Experimental measurements made on preamplifiers built with tubes, Nuvistors, and field effect transistors confirm the theoretical predictions with good accuracy. When the detector capacitance is 20pf, the preamplifiers exhibited noise charges of 310, 360 and 670 electronic charges respectively. The E810F tube is superior to other tubes currently used, while the field effect transistor is, at present, the best solid-state device.
Dissipation of the sectored heliospheric magnetic field near the heliopause: a mechanism for the generation of anomalous cosmic rays

description: The recent observations of the anomalous cosmic ray (ACR) energy spectrum as Voyagers 1 and 2 crossed the heliospheric termination shock have called into question the conventional shock source of these energetic particles. We suggest that the sectored heliospheric magnetic field, which results from the flapping of the heliospheric current sheet, piles up as it approaches the heliopause, narrowing the current sheets that separate the sectors and triggering the onset of collisionless magnetic reconnection. Particle-in-cell simulations reveal that most of the magnetic energy is released and most of this energy goes into energetic ions with significant but smaller amounts of energy going into electrons. The energy gain of the most energetic ions results from their reflection from the ends of contracting magnetic islands, a first order Fermi process. The energy gain of the ions in contracting islands increases their parallel (to the magnetic field ${\bf B}$) pressure $p_\parallel$ until the marginal firehose condition is reached, causing magnetic reconnection and associated particle acceleration to shut down. The model calls into question the strong scattering assumption used to derive the Parker transport equation and therefore the absence of first order Fermi acceleration in incompressible flows. A simple 1-D model for particle energy gain and loss is presented in which the feedback of the energetic particles on the reconnection drive is included. The ACR differential energy spectrum takes the form of a power law with a spectral index slightly above 1.5. The model has the potential to explain several key Voyager observations, including the similarities in the spectra of different ion species.

description: We investigate the new type of excitations on the surface of liquid helium. These excitations, called surfons, appear because helium atoms have discrete energy level at the liquid surface, being attracted to the surface by the van der Waals force and repulsed at a hard-core interatomic distance. The concentration of the surfons increases with temperature. The surfons propagate along the surface and form a two-dimensional gas. Basing on the simple model of the surfon microscopic structure, we estimate the surfon activation energy and effective mass for both helium isotopes. We also calculate the contribution of the surfons to the temperature dependence of the surface tension. This contribution explains the great and long-standing discrepancy between theory and experiment on this temperature dependence in both helium isotopes. The achieved agreement between our theory and experiment is extremely high. The comparison with experiment allows to extract the surfon activation energy and effective mass. The values of these surfon microscopic parameters are in a reasonable agreement with the calculated from the proposed simple model of surfon structure.

This expression illustrates how radiative processes soften the forward angle singularity so that the cross-section for all electrons which have radiated an energy larger that a given amount ΔE, is only logarithmically divergent as m_e→0. Estimate of the total integrated rate at a \\phi-factory are given, and a comparison is made with existing calculations.

description: The-coefficient and pole-zero locations of a transfer function F(s) having m zeros and n poles may be determined by imposing a total of (m+n-l) conditions on the magnitude and phase of F(s) at the origin. If q of these conditions are used to adjust the first q even derivatives of the magnitude of F(s), then (m+n-l-q) conditions may be used to adjust the first (m+n-l-q) even derivatives of the phase slope. By varying these indices m, n, and q, a family of functions may be obtained in which the Butterworth and Bessel-polynomial functions are special cases. A new approach described in this thesis yields some transfer functions which have not been treated in the literature. The step-function response is studied for the realizable solutions, and the relative merits of emphasizing flat magnitude and flat delay are compared.
J/ψ Production Via Fragmentation at the Tevatron
Creators: name: M. Cacciari

Publisher: name: INFN Open Access Repository
Year: 1994

description: The production of J/ψ at large transverse momenta (p_⊥>M_(J/ψ)) in pp ̅ collisions is considered by including the mechanism of fragmentation. Both contributions of fragmentation to J/ψ and of fragmentation to X states followed by radiative decay to J/ψ are taken into account. The latter is found to be dominant and larger than direct production. The overall theoretical estimate is shown to be nearly consistent with the experimental observation.
FINUDA Technical Report
Creators: name: Collaboration, The FINUDA
Publisher: name: INFN Open Access Repository
Year: 1995

description: The present document contains an up-to-date overview of the status of the FINUDA detector. The basic design and the main physics issues remain those of the proposal. However, a considerable deal of improvements and adaptation to the machine needs was performed and the detector design is, at present, nearly frozen. Also the tests on prototypes are pratically completed, and all sub-detectors are passing to the phase of tendering and mass productions, with the objective of having the detector components ready for mid '96.

Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2005
Subjects: subject: Konferenzschrift
subject: 510

description: Numerical upscaling is often the only way in which various multiscale problems can be handled. Numerics related to solving auxiliary problems appearing in asymptotic homogenization, as well as numerical treatment of multiscale problems with non-separable scales, are discussed here. Among the main topics discussed, are classification of multiscale problems and multiscale numerical algorithms; deriving coarse scale approximations via approximate truncations or based on variational principles; iterations over scales; accuracy and robustness of numerical upscaling algorithms; similarity and differences between different approaches (multigrid, multiscale FEM, heterogeneous multiscale method, etc.); convergence issues; area of applicability of the numerical upscaling, etc.
VME - Real - Time Data Acquisition for the Ultracryogenic Gravitational Antenna of Third Generation
Creators: name: G. Mazzitelli
Publisher: name: INFN Open Access Repository
Year: 1996

description: We describe a new design of the front-end electronics for the data acquisition of NAUTILUS, the first ultracryogenic resonant gravitational wave detector, operating in the INFN Laboratori Nazionali di Frascati. The improved sensitivity of this kind of detector poses new requirements on the data acquisition, as more speed, amplitude and timing accuracy are needed. In this work we discuss the results obtained with a new front-end configuration based on VME standard for a data acquisition rate of 5kHz (present rate 220Hz). We also describe the data acquisition system for the cosmic ray telescope assembled around NAUTILUS and the timing system of both the components.

description: How coral reefs survive as oases of life in low-productivity oceans has puzzled scientists for centuries. The answer may lie in internal nutrient cycling and/or input from the pelagic zone. Integrating meta-analysis, field data, and population modelling, we show that the ocean’s smallest vertebrates, cryptobenthic reef fishes, promote internal reef-fish biomass production through exceptional larval supply from the pelagic environment. Specifically, cryptobenthics account for two-thirds of reef-fish larvae in the near-reef pelagic zone, despite limited adult reproductive outputs. This overwhelming abundance of cryptobenthic larvae fuels reef trophodynamics via rapid growth and extreme mortality, producing almost 60% of consumed reef fish biomass. While cryptobenthics are commonly overlooked, their unique demographic dynamics may make them a cornerstone of ecosystem functioning on modern coral reefs.

Mini-Workshop: Particle Systems with Several Conservation Laws: Fluctuations and Hydrodynamic Limit
Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2005
Subjects: subject: Konferenzschrift
subject: 510

description: The Mini-Workshop is concerned with the large-scale description of microscopic many-particle systems with two or more conservation laws. This is topic of common interest for statistical mechanics, probability theory and PDE theory. The main difficulty lies in the proof of the hydrodynamic limit in terms of a system of (generically hyperbolic) PDE’s which includes a proper treatment of shock and boundary discontinuities that result from the microscopic dynamics. Moreover, fundamental properties of current-carrying stationary states of such systems (which are not Gibbs states) are studied in terms of fluctuations of macroscopic quantities. Many powerful tools developed for particle systems (or PDE’s respectively) with one conservation law have no obvious generalization to systems with two or more conservation laws and hence new mathematical ideas need to be developed.
Al Coordination and Local Structure in Minerals: XAFS Determinations and Multiple-Scattering Calculations for K-Feldspars

description: The Al K-edge spectra of three potassium feldspars KAlSi3O8: sanidine, microcline and orthoclase, all with four-fold-coordinated Al, have been measured by X-ray absorption near-edge structure spectroscopy and calculated according to the multiple-scattering formalism using clusters of different sizes and the Xa exchange-correlaition potential. Although these structures are quite complex, and clusters as large as containing ca. 150 atoms are needed to calculate them, a significant agreement has been obtained between experimental spectra and calculated ones up to 60 eV above the threshold, both for energy positions and for relative intensities. Moreover, while the gross features of all spectra appear to be dominated mainly by the first coordination sphere around the absorber, effects due to higher shells are detected.

description: The nucleon magnetic form factors in the unphysical region, i.e. for time-like Q^2 but below the NN ̅ threshold, have been obtained by means of dispersion relations in a model independent way, without any bias towards expected resonances. Space-like and time-like data have been employed along with a regularization unfolding method to solve integral equation. Remarkably, resonance structures with peaks for the ρ(770) and ρ'(1600) and a structure near the NN ̅ threshold are automatically generated. The obtained r has a much larger width, whose significance is explored. No evidence is found for a peak at the F mass, in spite of the expectation if there is a sizeable polarized ss ̅ content in the nucleon.

A study of the acceleration programme at West Vancouver Senior High School
Creators: name: Cullis, Harry E.
Publisher: name: University of British Columbia
Year: 2011

description: The West Vancouver Acceleration Programme was started in 1955 under the direction of the British Columbia Department of Education. It was part of an experiment carried out in three separate schools, to see if some of the top academic students could complete the regular High School curriculum, Grades 9-12, in three instead of four years. The 'above average students' were grouped into special classes in which both acceleration and enrichment took place. In this context, the 'above average students' were those students whose I.Q. was 113 or better and who had achieved consistently high results in the academic subjects English, Mathematics, Social Studies and Science. The question asked was: Have the accelerated students at West Vancouver Senior High School attained an academic standard in three years as high as that attained by a matched group of regular programme students in four years? The experimental group consisted of two divisions of accelerated students at the Grade 12 level, who covered the last four years of the regular High School programme in three years, completing it in 1958. The control group was drawn from the two top divisions of the regular Grade 12 students who were of comparable ability to the accelerated students, and who would probably have been on the "Acceleration Programme" had it commenced one year earlier. The marks used for comparison purposes were those obtained in the 1958 internal Easter examinations. The two groups were matched for I.Q. and the comparison carried out on a subject basis. In Mathematics a statistically significant difference between the means of the marks obtained was found in favour of the accelerated group. In Physics, French and Latin no significant difference was found. It was concluded that in general the accelerated students achieved an academic standard in three years as high as the regular programme students achieved in four years.
Polarized Spots in Anisotropic Open Universes

description: We calculate the temperature and polarization patterns generated in anisotropic cosmological models drawn from the Bianchi classification. We show that localized features in the temperature pattern, perhaps similar to the cold spot observed in the Wilkinson Microwave Anisotropy Probe (WMAP) data, can be generated in models with negative spatial curvature, i.e. Bianchi types V and VII$_{h}$. Both these models also generate coherent polarization patterns. In Bianchi VII$_h$, however, rotation of the polarization angle as light propagates along geodesics can convert E modes into B modes but in Bianchi V this is not necessarily the case. It is in principle possible, therefore, to generate localized temperature features without violating existing observational constraints on the odd-parity component of the polarization of the cosmic microwave background.
