description: Entangled networks of stiff biopolymers exhibit complex dynamic response, emerging from the topological constraints that neighboring filaments impose upon each other. We propose a class of reference models for entanglement dynamics of stiff polymers and provide a quantitative foundation of the tube concept for stiff polymers. For an infinitely thin needle exploring a planar course of point obstacles, we have performed large-scale computer simulations proving the conjectured scaling relations from the fast transverse equilibration to the slowest process of orientational relaxation. We determine the rotational diffusion coefficient of the tracer, its angular confinement, the tube diameter and the orientational correlation functions.

Volume 9: Issue 4: Battery Energy Storage at Scale
In this special issue of IEEE Electrification Magazine, we present five feature articles and two columns that address several important aspects of large-scale energy storage deployment. This issue also includes two interesting feature articles on the hyperloop technology that has great potential to reduce carbon emissions in the transportation sector but adds additional requirements on the electricity sector, which energy storage can play an important role to support.
Recruitment into the role of professor of teacher education in physical education
Creators: name: Mitchell, Murray F.
Publisher: name: University of British Columbia
Year: 2010

description: Research on teacher educators in physical education has been the exception, rather than the rule, despite their importance in teacher preparation programs. Fifteen teacher educators possessing a doctoral degree and experience in public schools were selected as subjects from four universities in an effort to launch systematic inquiry in this area of scholarly need. Structured interviews were used to gain information about their recruitment into their professorial roles and their current role orientations. Among the findings was a lack of consensus among them regarding the Ideal teacher, physical education program, teacher educator, and teacher education program, a dominant socialization pattern in which biography emerged as more important than formal education, and personal work priorities that often conflict with institutional reward systems. Five conclusions and their attendant implications emerged from the related findings and signal future research directions.

description: The aim of this paper is to present the construction, out of the Kohn-Rossi complex, of a new hypoelliptic operator $Q_{L}$ on almost CR manifolds equipped with a real structure. The operator acts on all (p,q)-forms, but when restricted to (p,0)-forms and (p,n)-forms it is a sum of squares up to sign factor and lower order terms. Therefore, only a finite type condition condition is needed to have hypoellipticity on those forms. However, outside these forms $Q_{L}$ may fail to be hypoelliptic, as it is shown in the example of the Heisenberg group. We also look at the Fredholm properties of $Q_{L}$ and show that the corresponding Fredholm index is zero.

The effects of forest management on carbon dynamics of soil organic horizons
Creators: name: Lanfranchi, Mauro
Publisher: name: Lancaster University
Year: 2020

description: The carbon sink potential of temperate forests plays a central role in climate change mitigation strategies, and soil organic carbon sequestration can be achieved through afforestation and reforestation. Yet, the main factors responsible for influencing the dynamics of long-term forest carbon stabilization within the soil are poorly understood. This study investigates how different forest management practices affect the carbon sequestration potential within the soil organic surface horizon (Litter, Fragmented and Humic) under second rotation Picea sitchensis plantations in the UK. Fieldwork activities were carried out in two experimental sites of upland Britain to collect samples related to soil carbon quantity, carbon quality and the dynamics of fine root turnover. Two separate experiments were carried out. The first was on a pre-existing experimental site (Forest of Ae) to assess differences between conventional stem-only harvest, whole-tree harvest and fertilization. The second experiment was designed on an existing trial (Clocaenog forest) to compare a stand with no interventions in the overstory or understory since the research area was established in 2002 (Control), and one stand in transformation to continuous cover forestry (irregular shelterwood). At the Forest of Ae, results revealed that fertilization practices had a significant, positive effect on soil carbon storage within the L horizon (conventional harvest p < 0.01, whole-tree harvest p < 0.01). Brash retained on site at the time of harvesting had a significant, positive effect on soil carbon storage within the F horizon (conventional harvesting p = 0.03 and fertilization p = 0.01). Results also suggest that soil nitrogen concentration can be used to predict the soil carbon storage of each organic horizon (adjR2= 0.931). Also, the fine root necromass within the 15 to 30 cm soil depth is significantly higher (p = 0.02) in the fertilized treatment when compared with whole-tree harvest, although this does not affect the carbon storage within the H horizon. At Clocaenog forest, transformation to irregular shelterwood had a highly significant, positive effect on soil carbon storage within the soil H horizon (p < 0.01). Soil nitrogen concentration, C:N ratios and available nitrogen all consistently point towards a higher presence of nitrogen in the Control treatment which could be responsible for SOC and N mineralization in the H horizon. Overall, the study shows that forest management decisions do affect C storage in the organic soil horizons of commercial forest plantations in upland Britain. These dynamics need to be taken into account in C and GHG balances and guidelines for soil protection.

description: This paper reports the Suzaku results on the northeast shell of RCW 86. With the spatial and spectral analysis, we separated the X-rays into three distinct components; low (kT_e~0.3keV) and high (kT_e~1.8keV) temperature plasmas and a non-thermal component, and discovered their spatial distributions are different from each other. The low temperature plasma is dominated at the east rim, whereas the non-thermal emission is the brightest at the northeast rim which is spatially connected from the east rim. The high temperature plasma, found to contain the ~6.42keV line (K alpha of low-ionized iron), is enhanced at the inward region with respect to the east rim and has no spatial correlation with the non-thermal X-ray (the northeast). The Fe-Kalpha line, therefore, is not related to the non-thermal emission but originates from Fe-rich ejecta heated to the high temperatures by the reverse shock. Since the metal abundances of the low temperature plasma are sub-solar, the most possible origin of this component is interstellar medium heated by a blast wave. The non-thermal X-ray, which has a power-law index of ~2.8, is likely to be synchrotron emission. A possible scenario to explain these morphologies and spectra is: A fast moving blast wave in a thin cavity of OB association collided with a dense interstellar medium or cloud at the east region very recently. As the result, the reverse shock in this interior decelerated, and arrived at the Fe-rich region of the ejecta and heated it. In the northeast rim, on the other hand, the blast wave is still moving fast, and accelerated high energy electrons to emit synchrotron X-rays.

description: We present the unsaturated peak profile of SGR 1900+14 giant flare on 1998 August 27. This was obtained by particle counters of the Low Energy Particle instrument onboard the GEOTAIL spacecraft. The observed peak profile revealed four characteristic structures: initial steep rise, intermediate rise to the peak, exponential decay and small hump in the decay phase. From this light curve, we found that the isotropic peak luminosity was $2.3\times10^{46}$ erg s$^{-1}$ and the total energy was $4.3 \times 10^{44}$ erg s$^{-1}$ ($E\gtrsim$ 50 keV), assuming that the distance to SGR 1900+14 is 15 kpc and that the spectrum is optically thin thermal bremsstrahlung with $kT =$ 240 keV. These are consistent with the previously reported lower limits derived from Ulysses and Konus-Wind observations. A comparative study of the initial spikes of SGR 1900+14 giant flare in 1998 and SGR 1806-20 in 2004 is also presented. The timescale of the initial steep rise shows the magnetospheric origin, while the timescale of the intermediate rise to the peak indicates that it originates from the crustal fracturing. Finally, we argue that the four structures and their corresponding timescales provide a clue to identify extragalactic SGR giant flares among short GRBs.

Is the shell-focusing singularity of Szekeres space-time visible?

description: The visibility of the shell-focusing singularity in Szekeres space-time - which represents quasi-spherical dust collapse - has been studied on numerous occasions in the context of the cosmic censorship conjecture. The various results derived have assumed that there exist radial null geodesics in the space-time. We show that such geodesics do not exist in general, and so previous results on the visibility of the singularity are not generally valid. More precisely, we show that the existence of a radial geodesic in Szekeres space-time implies that the space-time is axially symmetric, with the geodesic along the polar direction (i.e. along the axis of symmetry). If there is a second non-parallel radial geodesic, then the space-time is spherically symmetric, and so is a Lema\^ıtre-Tolman-Bondi (LTB) space-time. For the case of the polar geodesic in an axially symmetric Szekeres space-time, we give conditions on the free functions (i.e. initial data) of the space-time which lead to visibility of the singularity along this direction. Likewise, we give a sufficient condition for censorship of the singularity. We point out the complications involved in addressing the question of visibility of the singularity both for non-radial null geodesics in the axially symmetric case and in the general (non-axially symmetric) case, and suggest a possible approach.

description: In this paper, we construct (many) Kolyvagin systems out of Stickelberger elements, utilizing ideas borrowed from our previous work on Kolyvagin systems of Rubin-Stark elements. We show how to apply this construction to prove results on the odd parts of the ideal class groups of CM fields which are abelian over a totally real field, and deduce the main conjecture of Iwasawa theory for totally real fields (for totally odd characters). Although the main results of this paper have already been established by Wiles, our approach provides another example (which slightly differs from the case of Stark elements) on how to study Kolyvagin systems of core rank r > 1 (in the sense of Mazur and Rubin). Also, by making use of the 'rigidity' of the collection of Kolyvagin systems, we establish a link between the Stickelberger elements and the Rubin-Stark elements.

Webinar Slides - SPS Webinar, February 24 2022, Dr. Samet Akcay
X-ray security screening is widely utilized in aviation and transportation, and its importance has sparked interest in automated screening systems. The goal of this webinar is to explore computerized X-ray security imaging methods by classifying them into traditional machine learning and modern deep learning applications. The talk briefly reviews the traditional machine learning methodologies used in X-ray security imaging, and subsequently delves deeper into the applications of recent deep learning-based algorithms. The suggested taxonomy divides deep learning applications into supervised and unsupervised learning categories, with a focus on object categorization, detection, segmentation, and anomaly detection. The session goes on to look at some well-known X-ray datasets and presents a performance benchmark. The talk will be concluded with a discussion and future directions for X-ray security imagery, based on current and future advances in deep learning.

description: We consider classical potential scattering. If no orbit is trapped at energy E, the Hamiltonian dynamics defines an integer-valued topological degree. This can be calculated explicitly and be used for symbolic dynamics of multi-obstacle scattering. If the potential is bounded, then in the non-trapping case the boundary of Hill's Region is empty or homeomorphic to a sphere. We consider classical potential scattering. If at energy E no orbit is trapped, the Hamiltonian dynamics defines an integer-valued topological degree deg(E) < 2. This is calculated explicitly for all potentials, and exactly the integers < 2 are shown to occur for suitable potentials. The non-trapping condition is restrictive in the sense that for a bounded potential it is shown to imply that the boundary of Hill's Region in configuration space is either empty or homeomorphic to a sphere. However, in many situations one can decompose a potential into a sum of non-trapping potentials with non-trivial degree and embed symbolic dynamics of multi-obstacle scattering. This comprises a large number of earlier results, obtained by different authors on multi-obstacle scattering.

Canted-spin-caused electric dipoles: a local symmetry theory

description: A pair of magnetic atoms with canted spins Sa, Sb can give rise to an electric dipole moment P. Several forms for the behavior of such a moment have appeared in the theoretical literature, some of which have been invoked to explain experimental results found in various multiferroic materials. The forms specifically are P1 ~ R x (Sa x Sb); P2 ~ Sa x Sb, and P3 ~ Sa (R . Sa) - Sb (R . Sb), where R is the relative position of the atoms and Sa, Sb are unit vectors. To unify and generalize these various forms we consider P as the most general quadratic function of the spin components that vanishes whenever Sa and Sb are collinear, i.e. we consider the most general expressions that require spin canting. The study reveals new forms. We generalize to the vector P, Moriya's symmetry considerations regarding the (scalar) Dzyaloshinskii-Moriya energy D. Sa x Sb (which led to restrictions on D). This provides a rigorous symmetry argument which shows that P1 is allowed no matter how high the symmetry of the atoms plus environment, and gives restrictions for all other contributions. The analysis leads to the suggestion of terms omitted in the existing microscopic models, suggests a new mechanism behind the ferroelectricity found in the 'proper screw structure' of CuXO2, X=Fe, Cr, and predicts an unusual antiferroelectric ordering in the antiferromagnetically and ferroelectrically ordered phase of RbFe(MoO4)2.
description: 11 pages, 2 figures. The present work is a considerable generalization of the earlier version. It corrects the statement in the abstract as to the generality of the expression for Delta. Clarification of the term 'canted-spin-caused' is given, and adds application to additional experimental examples
Slides for - 20 Years of Musical Genre Classification - Past, Present, and Future
Creators: Dr. George Tzanetakis
Publisher: name: IEEE
Year: 2020

Webinar Slides, July 15, 2020, Dr. George Tzanetakis
In 2000, compact discs were the dominant mode of music distribution and the use of digital compressed audio files for playback using computers was just beginning. Most of the research on analyzing music was done with symbolic representations rather than audio signals. The presenter, Dr. George Tzanetakis, is fascinated by pattern recognition, computer vision, and speech recognition. His curiosity on the topic led him to research whether similar approaches could be followed to analyze audio recordings of music.  His most influential and pioneering publication ?Musical Genre Classification of Audio Signals? was the product of these investigations and heavily influenced the development of research field of Music Information Retrieval (MIR).

In this webinar, Dr. Tzanetakis will discuss the main ideas introduced in the paper, provide some historical context about their development, and trace their impact over the last 20 years.  By telling this story, he hopes to encourage graduate students and young researchers to think about how to conduct research that has long term impact.
Photo fragmentation of large dimers into singly charged ions via the knockout mechanism

Publisher: name: arXiv
Year: 2021
Subjects: subject: Atomic Physics (physics.atom-ph)

description: We study the fragmentation of very large dimers into two singly charged ions caused by absorption of a photon. In this process a photo electron emitted from one atom of the dimer has certain chances to hit the other atom knocking out one of its electrons. This results in the production of two singly charged ions and the consequent Coulomb explosion of the residual doubly charged system. We develop a theory of this process and apply it to calculate the fragmentation of $^4$He$_2$, $^7$Li - $^4$He and $^6$Li - $^4$He dimers. Our results for the helium dimer are in good agreement with available experimental data. For the Li-He dimers (where experimental data are still absent) our results predict that this fragmentation mechanism becomes much more efficient than in the case of He$_2$. We also show that, provided the recoil effects are of minor importance, the so called reflection approximation is very accurate also for large dimers.

On the structure of relativistic collisionless shocks in electron-ion plasmas
Creators: name: Spitkovsky, Anatoly
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Relativistic collisionless shocks in electron-ion plasma are thought to occur in the afterglow phase of Gamma-Ray Bursts (GRBs), and in other environments where relativistic flows interact with the interstellar medium. A particular regime of shocks in an unmagnetized plasma has generated much interest for GRB applications. In this paper we present ab-initio particle-in-cell simulations of unmagnetized relativistic electron-ion shocks. Using long-term 2.5-dimensional simulations with ion-electron mass ratios from 16 to 1000 we resolve the shock formation and reach a steady-state shock structure beyond the initial transient. We find that even at high ion-electron mass ratios initially unmagnetized shocks can be effectively mediated by the ion Weibel instability with a typical shock thickness of ~50 ion skin-depths. Upstream of the shock the interaction with merging ion current filaments heats the electron component, so that the postshock flow achieves near equipartition between the ions and electrons, with electron temperature reaching 50% of the ion temperature. This energy exchange helps to explain the large electron energy fraction inferred from GRB afterglow observations.

Remarks
Most of the descriptive details of this species were provided by Wygodzinsky (1959a) as Stylifera impudica, except for some of the new characters described here for the diagnosis of the new genus which include the clypeal tufts, trichobothrial areas, coxal combs of macrochaetae, pattern and distribution of scales on appendages, and pretarsal microtrichia. Dorsal scales are illustrated in Fig. 19A–B and scales of different appendages in Fig. 19C–F. The scales of the coxae are rounded, but not orbicular (i.e., with the basal part not surrounding the insertion), with a finely denticulate apical margin. Femoral scales are similar in shape to coxal scales, but slightly smaller and apically narrower. Tibial scales are narrower and smaller than those of the femora. Scales covering styli are even smaller, with their apical margin more denticulate. Coxal combs have 3–6 macrochaetae, some of them as long as half the width of the coxa. Details of abdominal chaetotaxy are presented in Table 1, although most of them do not represent an increase of the variability given by Wygodzinsky.

description: The evolution of local defects such as dislocations and cracks often determines the performance of engineering materials. For a proper description and understanding of these phenomena, one needs to descend to a very small scale, at which the discreteness of the material emerges. Fully-resolved discrete numerical models often suffer from excessive computing expenses when used for application-scale considerations. More efficient multiscale simulation procedures are thus called for, capable of capturing the most significant microscopic phenomena while being computationally tractable. Two broad classes of methods are available in the literature. The first class considers the fully-resolved discrete system, which is subsequently reduced through suitable mathematical tools such as projection and reduced integration. The second class first homogenizes the discrete system into an equivalent continuum formulation, into which the main phenomena are added through specific enrichments. This paper provides a thorough comparison of the two different modeling philosophies in terms of their theory, accuracy, and performance. To this goal, two typical representatives are adopted: the Quasicontinuum method for the first class, and an effective continuum with an embedded cohesive zone model for the second class. Two examples are employed to demonstrate capabilities and limitations of both approaches: dislocation propagation and pile-up against a coherent phase boundary, and a three-point bending test of a concrete specimen with crack propagation. In both cases, the accuracy of the two methods is compared against the fully-resolved discrete reference model. It is shown that whereas continuum models with embedded cohesive zones offer good performance to accuracy ratios, they might fail to capture unexpected mechanical behavior. The Quasicontinuum method offers more flexibility at a higher computational cost.

description: Significant systematic errors in high-precision Penning trap mass spectrometry can result from electric and magnetic field imperfections. An experimental procedure to minimize these uncertainties is presented for the on-line Penning trap mass spectrometer ISOLTRAP, located at ISOLDE/CERN. The deviations from the ideal magnetic and electric fields are probed by measuring the cyclotron frequency and the reduced cyclotron frequency, respectively, of stored ions as a function of the time between the ejection of ions from the preparation trap and their capture in the precision trap, which influences the energy of their axial motion. The correction parameters are adjusted to minimize the frequency shifts.

description: The $Q^2$ dependence of the ratio of the cross sections with and without proton spin flip, as well as the polarization asymmetry in the process $e \vec{p} \to e \vec{p}$ has been numerically analyzed using the results of JLab polarization experiments on the measurements of the ratio of the Sachs form factors in the $\vec{e} p \to e \vec{p}$ process. The calculations have been made for the case where the initial (at rest) and final protons are fully polarized and have a common spin quantization axis, which coincides with the direction of motion of the final proton. The longitudinal polarization transfer to the proton has been calculated in the case of the partially polarized initial proton for a kinematics used in the experiment reported in [A. Liyanage et al. (SANE Collaboration), Phys. Rev. C 101, 035206 (2020)], where the double spin asymmetry was measured in the $\vec{e} \vec{p} \to e p$ process. A noticeable sensitivity of the polarization transfer to the proton to the form of the $Q^2$ dependence of the ratio $μ_p G_E/G_M$ has been found. This sensitivity may be used to conduct a new independent experiment to measure this dependence in the $ e \vec{p} \to e \vec{p}$ process. A criterion to assess the reliability of measurements of the ratio of Sachs form factors using the Rosenbluth technique has been proposed and used to analyze the results of two experiments.

description: We systemically investigate the nature of Ce 4f electrons in structurally layered heavy-fermion compounds CcmMnIn3m+2n (with M =Co, Rh, Ir, and Pt, m=l, 2, n=0 - 2), at low temperature using on-resonance angle-resolved photoemission spectroscopy. Three heavy quasiparticle bands f^0, f^1_7/2 and f^1_5/2 are observed in all compounds, but their intensities and energy locations vary greatly with materials. The strong f^0 states imply that the localized electron behavior dominates the Ce 4f states. The Ce 4f electrons are partially hybridized with the conduction electrons, making them have the dual nature of localization and itinerant. Our quantitative comparison reveals that the f^1_5/2 / f^0 intensity ratio is more suitable to reflect the 4f-state hybridization strength.

description: Let G be a finite abelian group with |G|>1. Let a_1,...,a_k be k distinct elements of G and let b_1,...,b_k be (not necessarily distinct) elements of G, where k is a positive integer smaller than the least prime divisor of |G|. We show that there is a permutation $π$ on {1,...,k} such that a_1b_{π(1)},...,a_kb_{π(k)} are distinct, provided that any other prime divisor of |G| (if there is any) is greater than k!. This in particular confirms the Dasgupta-Karolyi-Serra-Szegedy conjecture for abelian p-groups. We also pose a new conjecture involving determinants and characters, and show that its validity implies Snevily's conjecture for abelian groups of odd order. Our methods involve exterior algebras and characters.

description: Electromagnetic waves in a system with a space and time dependent boundary experience both diffraction and Doppler-like frequency conversion. In order to analyse such situations, conventional methods call for either the eigenmodes or the dyadic Green's function in space and time dependent media. Here, we propose a dynamical differential method which does not require either of them. Our method utilises a dynamical coordinate transformation in order to simplify the calculation of the optical response of the space and time dependent system. We reveal that the diffraction symmetry is broken in the presence of traveling-wave type spatiotemporal modulation.

title: Planning for a quality life: A theoretical approach to quality of life research in community planning
Creators: name: Dixon, Marilyn Emily

subject: Social accounting
subject: City planning

description: For many years measuring Gross Domestic Product (GDP) has been the standard to which success has been defined by cities and countries alike. Economic brilliance however, can only take us so far. Measuring quality of life (QOL) is quickly becoming the preferred way of measuring success in the built environment. But what does it mean? QOL is synonymous with terms like ‘happiness’, ‘well-being’ or ‘life satisfaction’, but includes a more holistic evaluation of them. The purpose of this research is to shed light on why it is we do the things we do, and to consider the role of a planner in a pragmatic way. All too often planning is considered to be idealistic where decisions are made on the basis of “best practices”. What this research intends to answer is; who are these ‘best practices’ looking to serve? Have we succeeded in doing what we set out to do? And to understand that just because a decision was made in the past to serve a particular goal, it may not equate to how we should be considering that goal now. What we should be asking ourselves is; what does success look like? Can we define it? Can we measure it? Are we happy? The objective of this research is not only to understand if measuring QOL can better inform policy decisions at a community level, but to understand which approach is worth taking. Some might say its subjectivity is not appropriate for informing policy or decision making. Others seem more optimistic of its potential, in that any movement towards progress should be studied, and is worth while. This research seeks to recognize the extent to which community planning impacts our QOL, with respect to the built environment, and the role government plays in decision making.
