description: Objectives: We compared the ability of physical activity and sitting time questionnaires (PAQ) for ranking individuals versus continuous volume calculations (physical activity level (PAL), metabolic equivalents of task (MET), sitting hours) against accelerometry measured physical activity as our criterion. Methods: Participants in a cohort from the Tromsø Study completed three questionnaires; (1) The Saltin-Grimby Physical Activity Level Scale (SGPALS) (n=4040); (2) The Physical Activity Frequency, Intensity and Duration (PAFID) questionnaire (n=5902)) calculated as MET-hours·week-1 and (3) The International Physical Activity questionnaire (IPAQ) short-form sitting question (n=4896). We validated the questionnaires against the following accelerometry (Actigraph wGT3X-BT) estimates: vector magnitude counts per minute, steps∙day-1, time (minutes·day-1) in sedentary behaviour, light physical activity, moderate and vigorous physical activity (MVPA) non-bouted and ≥10 min bouted MVPA. Results: Ranking of physical activity according to the SGPALS and quartiles (Q) of MET-hours∙week-1 from the PAFID were both positively associated with accelerometry estimates of physical activity (p<0.001) but correlations with accelerometry estimates were weak (SGPALS (PAL): r=0.11 to 0.26, p<0.001) and weak-to-moderate (PAFID: r=0.39 to 0.44, p<0.01). There was 1 hour of accelerometry measured sedentary time from Q1 to Q4 in the IPAQ sitting question (p<0.001) and also weak correlations (r=0.22, p<0.01). Conclusion: Ranking of physical activity levels measured with PAQs appears to have higher validity than energy expenditure calculations. Self-reported sedentary time poorly reflects accelerometry measured sedentary time. These two PAQs can be used for ranking individuals into different physical activity categories supporting previous studies using these instruments when assessing associations with health outcomes.

description: We formulate a momentum-shell renormalization group (RG) procedure that can be used in theories containing both bosons and fermions with a Fermi surface. We focus on boson-fermion couplings that are nearly forward-scattering, {\it i.e.} involving small momentum transfer ($\vec{q} \approx 0$) for the fermions. Special consideration is given to phase space constraints that result from the conservation of momentum and the imposition of ultraviolet cutoffs. For problems where the energy and momentum scale similarly (dynamic exponent $z = 1$), we show that more than one formalism can be used and they give equivalent results. When the energy and momentum must scale differently ($z \neq 1$), the procedures available are more limited but a consistent RG scheme can still be formulated. Our approach is applicable to a variety of problems in condensed matter physics, such as itinerant-electron magnets and gauge fields interacting with fermions.

description: We have observed 152 nearby solar-type stars with the Infrared Spectrometer (IRS) on the Spitzer Space Telescope. Including stars that met our criteria but were observed in other surveys, we get an overall success rate for finding excesses in the long wavelength IRS band (30-34 micron) of 11.8% +/- 2.4%. The success rate for excesses in the short wavelength band (8.5-12 micron) is ~1% including sources from other surveys. For stars with no excess at 8.5-12 microns, the IRS data set 3 sigma limits of around 1,000 times the level of zodiacal emission present in our solar system, while at 30-34 microns set limits of around 100 times the level of our solar system. Two stars (HD 40136 and HD 10647) show weak evidence for spectral features; the excess emission in the other systems is featureless. If the emitting material consists of large (10 micron) grains as implied by the lack of spectral features, we find that these grains are typically located at or beyond the snow line, ~1-35 AU from the host stars, with an average distance of 14 +/- 6 AU; however smaller grains could be located at significantly greater distances from the host stars. These distances correspond to dust temperatures in the range ~50-450 K. Several of the disks are well modeled by a single dust temperature, possibly indicative of a ring-like structure. However, a single dust temperature does not match the data for other disks in the sample, implying a distribution of temperatures within these disks. For most stars with excesses, we detect an excess at both IRS and MIPS wavelengths. Only three stars in this sample show a MIPS 70 micron excess with no IRS excess, implying that very cold dust is rare around solar-type stars.

description: Objectives: We have previously identified a delay in general practitioner (GP) referrals for patients with degenerative cervical myelopathy (DCM). The aim of this study was to evaluate whether an education gap existed for DCM along the GP training pathway by quantitatively assessing training in, and knowledge of, this condition. Design: Gap analysis: comparison of DCM to other conditions. Comparators selected on the basis of similar presentation/epidemiology (multiple sclerosis), an important spinal emergency (cauda equina syndrome) and a common disease (diabetes mellitus). Subjects: Medical students, foundation doctors and GP trainees. Primary and secondary outcome measures: (1) Assessment of training: quantitative comparison of references to DCM in curricula (undergraduate/postgraduate) and commonly used textbooks (Oxford Handbook Series), to other conditions using modal ranks. (2) Assessment of knowledge: using standardised questions placed in an online question-bank (Passmedicine). Results were presented relative to the question-bank mean (+/−). Results: DCM had the lowest modal rank of references to the condition in curricula analysis and second lowest modal rank in textbook analysis. In knowledge analysis questions were attempted 127 457 times. Performance for DCM questions in themes of presentation (+6.1%), workup (+0.1%) and management (+1.8%) were all greater than the question-bank mean and within one SD. For students and junior trainees, there was a serial decrease in performance from presentation and workup (−0.7% to +10.4% relative to question-bank mean) and management (−0.6% to −3.9% relative to question-bank mean). Conclusions: Although infrequently cited in curricula and learning resources, knowledge relating to DCM was above average. However, knowledge relating to its management was relatively poor.
Learning from imbalanced data : a geometric study on over-parameterized models
Creators: name: Behnia, Tina
Publisher: name: University of British Columbia
Year: 2023

description: Machine learning has trended toward training overparameterized networks that can exactly fit the training set. In this regime, when the training data is class-imbalanced, traditional methods for mitigating imbalances are not effective and yield poor performance on minorities. Tailored to the over-parameterized setting, one successful technique to combat imbalances involves adjusting the logits during training by introducing several hyper-parameters in the cross-entropy loss. The idea behind these adjustments is rooted in the implicit bias analysis which, for linear models, explains why they successfully induce bias on the optimization path towards solutions that favor minorities. However, the impact of these adjustments is not well-understood for deep, non-linear models that simultaneously learn features from the data and fit classifiers on them. In this work, we take a step towards formalizing the impact of data imbalances and the choice of loss function when learning in over-parameterized setups. At the core of our analysis is the unconstrained features model (UFM), which recently provided partial theoretical justification for the empirical finding known as Neural-collapse. Limited to the balanced setting, Neural-collapse suggests that over-parameterized models learn features and classifiers that are arranged in a perfectly symmetric and maximally-separated geometry. Leveraging the UFM in our analysis, we analytically characterize the changes in the learned geometry as data becomes imbalanced or the loss function is modified. Our analysis characterizes the properties of the learned features and classifiers, justifying previously observed empirical findings on imbalanced training. To verify the accuracy of our theoretical predictions, we conduct experiments on benchmark networks and vision datasets. Additionally, we adopt the UFM to conduct a preliminary study on supervised contrastive loss, a recently proposed alternative to the cross-entropy. We observe that these two losses, under UFM, exhibit certain similarities. Furthermore, with a slight modification to the model, we discover that we can make the training geometry invariant to imbalances in this case. Overall, despite its simplicity, UFM uncovers certain biases of over-parameterized models at the training stage. Indeed, this simplification is not without its own limitations, which will become clear throughout our analysis.

description: This paper examines the importance of the human capital development in diversifying Nigerian economy, especially, given the fact that it is oil base economy. It argues that to achieve a successful diversification more time and other resources are required into developing human capital which will exert great impact on the direction of the nation economy. For this, the need for adequate investment in education and training, health and safety, infrastructural facilities and a hostile free work environment are necessary for these human elements to strive in different sectors of the economy. This paper review the effect human capitals have on the economy of Nigeria. It also proposes a framework for new direction. Finally, the paper went further to explain that, in doing so, the accumulated wealth of knowledge, skills, and competencies acquired by the human element remains a great asset to creating several innovative ideas that will re-direct the Nigerian economy from mono-product (oil) to non-oil sectors for future economic development.

We apply MMP algorithms to obtain smallest OMLs with 35 atoms and 35 blocks (35-35) and all other ones up to 38-38. We find out that all but one of them admit exactly one state and discover several other properties of theirs. Previously known such OMLs have 44 atoms and 44 blocks or more. We present some of them in our notation.

As an example, we define homotopy topological conformal field theories and observe that such structures are homotopy invariant.

description: We create a model for recovering the intrinsic, absorption-corrected surface brightness distribution of a galaxy and apply the model to the M31. We construct a galactic model as a superposition of axially symmetric stellar components and a dust disc to analyse the intrinsic absorption efects. Dust column density is assumed to be proportional to the far-infrared flux of the galaxy. Along each line of sight, the observed far-infrared spectral energy distribution is approximated with modified black body functions considering dust components with different temperatures, allowing to determine the temperatures and relative column densities of the dust components. We apply the model to the nearby galaxy M31 using the Spitzer Space Telescope far-infrared observations for mapping dust distribution and temperature. A warm and a cold dust component are distinguished. The temperature of the warm dust in M31 varies between 56 and 60 K and is highest in the spiral arms; the temperature of the cold component is mostly 15-19 K and rises up to about 25 K at the centre of the galaxy. The intensity-weighted mean temperature of the dust decreases from T ~32 K at the centre to T ~20 K at R ~7 kpc and outwards. We also calculate the intrinsic UBVRIL surface brightness distributions and the spatial luminosity distribution. The intrinsic dust extinction in the V-colour rises from 0.25 mag at the centre to 0.4-0.5 mag at R = 6-13 kpc and decreases smoothly thereafter. The calculated total extinction-corrected luminosity of M31 is L_B = (3.64 pm 0.15) 10^10L_sun, corresponding to an absolute luminosity M_B = (-20.89 pm 0.04) mag. Of the total B-luminosity, 20% (0.24 mag) is obscured from us by the dust inside M31. The intrinsic shape of the bulge is slightly prolate in our best-fit model.

description: One of the main challenges of the Tevatron at Fermilab and the Large Hadron Collider (LHC) at CERN is the determination of Standard Model (SM) parameters at the TeV scale. In this context various processes will be investigated which involve bottom-quark jets in the final state, for example decays of top-quarks or gauge bosons of the weak interaction. Hence the theoretical understanding of processes with bottom-quark jets is necessary. In this paper analytic results will be presented for the weak corrections to bottom-quark jet production -- neglecting purely photonic corrections. The results will be used to study differential distributions, where sizeable effects are observed.

description: Excerpt from the report Summary: Of the approximately 1,900 mutual insurance companies that have more than half of their windstorm insurance on farm property, 65 are specialized windstorm companies and about 348 are fire mutuals that also offer windstorm insurance. The extent of the operations of about half of the specialized windstorm mutuals, and a third of the fire-wind mutuals, is at least State-wide. Most of the specialized companies are located in the North Central States, whereas about a third of the fire-wind companies are located in Ohio and Pennsylvania. The 413 companies probably had more than 13.5 billion dollars of windstorm insurance in force at the end of 1950, of which about 6.5 billions were on the books of the specialized companies.

description: We examine the alignment between Brightest Cluster Galaxies (BCGs) and their host clusters in a sample of 7031 clusters with 0.080.65 mag brighter than the mean of the second and third ranked galaxies) show stronger alignment than do clusters with less dominant BCGs at the 4.4 sigma level. Rich clusters show a stronger alignment than do poor clusters at the 2.3 sigma level. Low redshift clusters (z<0.26) show more alignment than do high redshift (z>0.26) clusters, with a difference significant at the 3.0 sigma level. Our results do not depend on the algorithm used to select the cluster sample, suggesting that they are not biased by systematics of either algorithm. The correlation between BCG dominance and cluster alignment may be a consequence of the hierarchical merging process which forms the cluster. The observed redshift evolution may follow from secondary infall at late redshifts.

description: In this paper we study the entanglement properties of free {\em non-relativistic} Bose gases. At zero temperature, we calculate the bipartite block entanglement entropy of the system, and find it diverges logarithmically with the particle number in the subsystem. For finite temperatures, we study the mutual information between the two blocks. We first analytically study an infinite-range hopping model, then numerically study a set of long-range hopping models in one-deimension that exhibit Bose-Einstein condensation. In both cases we find that a Bose-Einstein condensate, if present, makes a divergent contribution to the mutual information which is proportional to the logarithm of the number of particles in the condensate in the subsystem. The prefactor of the logarithmic divergent term is model dependent.

Contraception options and reproductive access (CORA) for newcomer youth in Canada : a qualitative knowledge translation investigation
Creators: name: Khan, Zeba
Publisher: name: University of British Columbia
Year: 2023

description: Access to contraception care, and the knowledge to make informed decisions about contraceptive choices is a critical aspect of reproductive autonomy. Yet, it remains out of reach for many newcomer youth in Canada. I aimed to describe the current literature on the experiences of newcomer youth’s access to contraception in Canada (Aim 1), explore the role of settlement service providers in making contraceptive care accessible to newcomer youth (Aim 2) and investigate the experiences of newcomer youth’s access to contraception care in Canada (Aim 3). I conducted a scoping review of published literature on the experiences of newcomer youth and summarized my findings. My scoping review revealed that sociocultural context is an important factor that determines newcomer youth’s access to contraception care, and culturally appropriate educational interventions can support their ability to access contraception. To explore the role of settlement service providers, I designed a knowledge translation activity consisting of two workshops and an infographic summarizing the key messages generated in the workshops. I learned that settlement service providers are trusted resources in the community who can help newcomer youth navigate contraception access. However, lack of training and referral pathways limit their ability to support youth. Finally, I conducted the analysis of fourteen qualitative one-to-one interviews with newcomers aged 15 to 25 years in Canada and applied a constructivist grounded theory analysis to generate novel theories to explain youth experiences. I identified five analytical themes: i) Sex is a shameful thing that we don’t talk about ii) Preferring contraception options that allow youth to ‘grab n go’ iii) I think you learn from and trust your friends iv) Ability to Seek and Pay v) Ability to Perceive and Engage. My interpretation of the interviews suggests that developing knowledge translation tools for newcomer youth that provide rich, narrative descriptions of various contraceptive methods, and include information on the attributes of contraception that are most important to them can help make contraception care more accessible to newcomer youth living in Canada. In addition, providing appropriate training and resources to settlement service providers can empower them to help newcomer youth navigate contraception care.

description: A non-Abelian geometric method is proposed for rotating of heavy hole spins in a singly positive charged quantum dot in Voigt geometry. The key ingredient is the delay-dependent non-Abelian geometric phase, which is produced by the nonadiabatic transition between the two degenerate dark states. We demonstrate, by controlling the pump, the Stokes and the driving fields, that the rotations about $y$- and $z$-axes with arbitrary angles can be realized with high fidelity. Fast initialization and heavy hole spin state readout are also possible.

description: We discuss Casimir phenomena which are dominated by long-range fluctuations. A prime example is given by "geothermal" Casimir phenomena where thermal fluctuations in open Casimir geometries can induce significantly enhanced thermal corrections. We illustrate the underlying mechanism with the aid of the inclined-plates configuration, giving rise to enhanced power-law temperature dependences compared to the parallel-plates case. In limiting cases, we find numerical evidence even for fractional power laws induced by long-range fluctuations. We demonstrate that thermal energy densities for open geometries are typically distributed over length scales of 1/T. As an important consequence, approximation methods for thermal corrections based on local energy-density estimates such as the proximity-force approximation are expected to become unreliable even at small surface separations.

description: It is nice to be able to hold a conference now for a telescope named after Nancy Grace Roman. For those of you who may not know who Nancy Grace Roman was, I wanted to give you a summary of some of her highlights of her career and accomplishments. She was an amazing, amazing woman. A very accomplished astronomer. Absolutely dedicated and consummate public servant. Someone who really persisted in the face of a lot of obstacles in her career path. She was the first woman on the astronomy faculty of the University of Chicago, but left the University eventually because she realized that she wasn't going to be promoted there. She went to work for NASA. She was the first chief of astronomy and the first woman to hold an executive position at NASA. She really was the person probably more than anyone who is responsible for shepherding NASA’s great observatories right behind the original Orbiting Astronomical Observatories in the late '60s and '70s right through to Hubble. The field of astronomy today would not be the same had it not been for Nancy Grace's persistence or love of science or absolute commitment to making sure that others could explore the universe and love science the way that she did. Beyond that, she was just a tremendous woman who was a joy to talk to. Someone who was a real champion for women and children. She volunteered for reading for the blind and dyslexic. She was an active member of her church. When I gave a statement at her memorial service at her church, I was honored to do that. And I was astounded by the love that that congregation had for her and the interest they had in her life. And so they were extremely pleased to hear that NASA decided to rename WFIRST after Nancy Grace. I think she would've also been very proud to have had the telescope named after her. I think she would've thought it was a very fitting way to cap her tremendous career. It's up to all of us now to make sure that we help that observatory live up to the legacy of her name and what she has done for us. So let's make sure that we do that. What are the things that we can do as part of a community is to come together and think broadly and deeply about the kinds of science that are in the realm of possibility with the Roman space telescope. She would've encouraged us to think broadly. I'm encouraging you to do the same today. Don't be bound by the past or deterred by obstacles in your past. Nancy Grace certainly wasn't. And neither should we be. We have a full program here in this particular conference. I wish all of you a good virtual conference here. Obviously, we would've liked to have done this in person. And there will again be a time when we can do that and help advance the science case for this tremendous observatory. For this week, we will do it virtually, which is the next best thing.
Interplay between disorder and local field effects in photonic crystal waveguides

description: We introduce a theory to describe disorder-induced scattering in photonic crystal waveguides, specifically addressing the influence of local field effects and scattering within high-index-contrast perturbations. Local field effects are shown to increase the predicted disorder-induced scattering loss and result in significant resonance shifts of the waveguide mode. We demonstrate that two types of frequency shifts can be expected, a mean frequency shift and a RMS frequency shift, both acting in concert to blueshift and broaden the nominal band structure. For a representative waveguide, we predict substantial meV frequency shifts and band structure broadening for a telecommunications operating frequency, even for state of the art fabrication. The disorder-induced broadening is found to increase as the propagation frequency approaches the slow light regime (mode edge) due to restructuring of the electric field distribution. These findings have a dramatic impact on high-index-contrast nanoscale waveguides, and, for photonic crystal waveguides, suggest that the nominal slow-light mode edge may not even exist. Furthermore, our results shed new light on why it has hitherto been impossible to observe the very slow light regime for photonic crystal waveguides.

Generation of Sound Bullets with a Nonlinear Acoustic Lens

Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Acoustic lenses are employed in a variety of applications, from biomedical imaging and surgery, to defense systems, but their performance is limited by their linear operational envelope and complexity. Here we show a dramatic focusing effect and the generation of large amplitude, compact acoustic pulses (sound bullets) in solid and fluid media, enabled by a tunable, highly nonlinear acoustic lens. The lens consists of ordered arrays of granular chains. The amplitude, size and location of the sound bullets can be controlled by varying static pre-compression on the chains. We support our findings with theory, numerical simulations, and corroborate the results experimentally with photoelasticity measurements. Our nonlinear lens makes possible a qualitatively new way of generating high-energy acoustic pulses, enabling, for example, surgical control of acoustic energy.

Probing Kitaev Models on Small Lattices

description: We address the following important question: how to distinguish Kitaev models experimentally realized on small lattices from other non-topological interacting spin models. Based on symmetry arguments and exact diagonalization, we show that a particularly characteristic pattern of spin-spin correlations survives despite finite size, open boundary and thermal effects. The pattern is robust against small residual perturbing interactions and can be utilized to distinguish the Kitaev interactions from other interactions such as antiferromagnetic Heisenberg interactions. The effect of external magnetic field is also considered and found to be not critical.
Accurate control of a Bose-Einstein condensate by managing the atomic interaction

description: We exploit the variation of the atomic interaction in order to move ultra-cold atoms across an AC-driven periodic lattice. By breaking relevant symmetries, a gathering of atoms is achieved. Accurate control of the gathered atoms positions can be demonstrated via the control of the atomic localization process. The localization process is analyzed with the help of the nonlinear Floquet states where the Landau-Zener tunneling between states is observed and controlled. Transport effects in the presence of disorder are discussed.

description: We use the integral-field spectrograph SAURON to measure the stellar line-of-sight velocity distribution and absorption line strengths out to four effective radii (Re) in the early-type galaxies NGC 3379 and NGC 821. With our newly developed observing technique we can now probe these faint regions in galaxies that were previously not accessible with traditional long-slit spectroscopy. We make optimal use of the large field-of-view and high throughput of the spectrograph: by adding the signal of all ~1400 lenslets into one spectrum, we obtain sufficient signal-to-noise in a few hours of observing time to reliably measure the absorption line kinematics and line strengths out to large radius. We find that the line strength gradients previously observed within 1 Re remain constant out to at least 4 Re, which puts constraints on the merger histories of these galaxies. The stellar halo populations are old and metal-poor. By constructing orbit-based Schwarzschild dynamical models we find that dark matter is necessary to explain the observed kinematics in NGC 3379 and NGC 821, with 30 - 50 per cent of the total matter being dark within 4 Re. The radial anisotropy in our best-fit halo models is less than in our models without halo, due to differences in orbital structure. The halo also has an effect on the Mgb - Vesc relation: its slope is steeper when a dark matter halo is added to the model.

description: A new accreting millisecond X-ray pulsar, IGR J17511-3057, was discovered in outburst on 2009 September 12 during the INTEGRAL Galactic bulge monitoring programme. To study the evolution of the source X-ray flux and spectral properties during the outburst, we requested a Swift monitoring of IGRJ17511-3057. In this paper we report on the results of the first two weeks of monitoring the source. The persistent emission of IGR J17511-3057 during the outburst is modeled well with an absorbed blackbody (kT~0.9 keV) and a power-law component (photon index~1-2), similar to what has been observed from other previously known millisecond pulsars. Swift also detected three type-I Xray bursts from this source. By assuming that the peak luminosity of these bursts is equal to the Eddington value for a pure helium type-I X-ray burst, we derived an upper limit to the source distance of ~10 kpc. The theoretical, expected recurrence time of the bursts according to the helium burst hypothesis is 0.2-0.9 days, in agreement with the observations.

description: We report measurements of the field and angular dependences of Jc of truly epitaxial Co-doped BaFe2As2 thin films grown on SrTiO3/(La,Sr)(Al,Ta)O3 with different SrTiO3 template thicknesses. The films show Jc comparable to Jc of single crystals and a maximum pinning force Fp(0.6Tc) > 5 GN/m3 at H/Hirr ~ 0.5 indicative of strong vortex pinning effective up to high fields. Due to the strong correlated c-axis pinning, Jc for field along the c-axis exceeds Jc for H//ab plane, inverting the expectation of the Hc2 anisotropy. HRTEM reveals that the strong vortex pinning is due to a high density of nanosize columnar defects.
