description: We perform a theoretical study of a fermionic gas with two hyperfine states confined to an optical lattice. We derive a generic state diagram as a function of interaction strength, particle number, and confining potential. We discuss the central density, the double occupancy and their derivatives as probes for the Mott state, connecting our findings to the recent experiment of Jördens et al. Using entropic arguments we compare two different strategies to reach the antiferromagnetic state in the presence of a trapping potential.

description: The di-photon decay channel of the lightest Higgs boson is considerd as a probe to explore CP violation in the Minimal Supersymmetric Standard Model (MSSM). The scalar/pseudo-scalar mixing is considered along with CP violation entering through the Higgs-sfermion-sfermion couplings, with and without light sparticles. The impact of a light stop on the decay width and Branching Ratio (BR) is established through a detailed study of the amplitude of the process H1 --> gamma.gamma. The other sparticles have little influence even when they are light. With a suitable combination of other MSSM parameters, a light stop can change the BR by more than 50 % with a CP-violating phase phi_mu ~ 90 deg., while the change is almost nil with a heavy stop.

description: We present a detailed study of the interface morphology of an electro-deposited (ED) Ni/Cu bilayer film by using off-specular (diffuse) neutron reflectivity technique and Atomic Force Microscopy (AFM). The Ni/Cu bilayer has been electro-deposited on seed layers of Ti/Cu. These two seed layers were deposited by magnetron sputtering. The depth profile of density in the sample has been obtained from specular neutron reflectivity data. AFM image of the air-film interface shows that the surface is covered by globular islands of different sizes. The AFM height distribution of the surface clearly shows two peaks [Fig. 3] and the relief structure (islands) on the surface in the film can be treated as a quasi-two-level random rough surface structure. We have demonstrated that the detailed morphology of air-film interfaces, the quasi-two level surface structure as well as morphology of the buried interfaces can be obtained from off-specular neutron reflectivity data. We have shown from AFM and off-specular neutron reflectivity data that the morphologies of electro-deposited surface is distinctly different from that of sputter-deposited interface in this sample. To the best of our knowledge this is the first attempt to microscopically quantify the differences in morphologies of metallic interfaces deposited by two different techniques viz. electro-deposition and sputtering.

description: Pulsar surveys offer one of the few opportunities to monitor even a small fraction (~0.00001) of the radio sky for impulsive burst-like events with millisecond durations. In analysis of archival survey data, we have discovered a 30-Jy dispersed burst of duration <5 ms located three degrees from the Small Magellanic Cloud. The burst properties argue against a physical association with our Galaxy or the Small Magellanic Cloud. Current models for the free electron content in the Universe imply a distance to the burst of <1 Gpc No further bursts are seen in 90-hr of additional observations, implying that it was a singular event such as a supernova or coalescence of relativistic objects. Hundreds of similar events could occur every day and act as insightful cosmological probes.

description: We use femtosecond optical pulses to induce, control and monitor magnetization precession in ferromagnetic Ga0.965Mn0.035As. At temperatures below ~40 K we observe coherent oscillations of the local Mn spins, triggered by an ultrafast photoinduced reorientation of the in-plane easy axis. The amplitude saturation of the oscillations above a certain pump intensity indicates that the easy axis remains unchanged above ~TC/2. We find that the observed magnetization precession damping (Gilbert damping) is strongly dependent on pump laser intensity, but largely independent on ambient temperature. We provide a physical interpretation of the observed light-induced collective Mn-spin relaxation and precession.

description: Background: Dental caries is a significant public health problem and one of the most common chronic conditions affecting children. The potential for the non-dental workforce to improve children's oral health is well documented. For well over a decade, there have been calls for pediatricians to address children's oral health, but the incorporation of oral health screening, referral, and oral healthcare in pediatric practice remains underdeveloped. Developing action to strengthen the role of pediatricians' in children's oral health requires an understanding of their current knowledge and practice. In this scoping review, we aimed to comprehensively map what is known about the knowledge and practice of pediatricians regarding children's oral health. Methods: Arksey & O'Malley's five-stage review process was used to comprehensively map studies undertaken on pediatrician's knowledge and practice regarding children's oral health. Key search terms were developed and a total of 42 eligible articles are included in the review. Results: The studies were conducted in 19 countries. The majority (41/42) were quantitative, with over 90% using self-reported surveys. Only four studies used previously validated survey tools, with most adapting questions from previous studies. Observational designs were used in two studies and one used qualitative methods. Sample size ranged from 15 to 862. Oral health knowledge amongst pediatricians was reported to be mostly poor, with many gaps in key areas including age for first dental visit, dental caries and oral health risk assessments. Studies on the translation of oral health knowledge to practice were limited, with wide variation in rates of assessment. Few studies assessed actual practice. Conclusions: This scoping review highlights growing international interest in the role of pediatricians in children's oral health. Findings demonstrate that pediatricians have limited knowledge and understanding in critical areas, including; initial clinical signs of dental caries, recommended age for first dental visit, etiology of dental caries and recommended use of fluorides. Barriers for pediatricians include inadequate education and training, time constraints in practice and lack of referral pathways. Development of a validated tool to assess knowledge and practice is needed. This review provides a starting point to guide future research and areas for systematic reviews.

description: The data augmentation (DA) algorithm is a widely used Markov chain Monte Carlo (MCMC) algorithm that is based on a Markov transition density of the form $p(x|x')=\int_{\mathsf{Y}}f_{X|Y}(x|y)f_{Y|X}(y|x') dy$, where $f_{X|Y}$ and $f_{Y|X}$ are conditional densities. The PX-DA and marginal augmentation algorithms of Liu and Wu [J. Amer. Statist. Assoc. 94 (1999) 1264--1274] and Meng and van Dyk [Biometrika 86 (1999) 301--320] are alternatives to DA that often converge much faster and are only slightly more computationally demanding. The transition densities of these alternative algorithms can be written in the form $p_R(x|x')=\int_{\mathsf{Y}}\int _{\mathsf{Y}}f_{X|Y}(x|y')R(y,dy')f_{Y|X}(y|x') dy$, where $R$ is a Markov transition function on $\mathsf{Y}$. We prove that when $R$ satisfies certain conditions, the MCMC algorithm driven by $p_R$ is at least as good as that driven by $p$ in terms of performance in the central limit theorem and in the operator norm sense. These results are brought to bear on a theoretical comparison of the DA, PX-DA and marginal augmentation algorithms. Our focus is on situations where the group structure exploited by Liu and Wu is available. We show that the PX-DA algorithm based on Haar measure is at least as good as any PX-DA algorithm constructed using a proper prior on the group.

The role of abandoned stream channels as over-wintering habitat for juvenile salmonids
Creators: name: Brown, Thomas Gordon
Publisher: name: University of British Columbia
Year: 2010

description: The role of ephemeral swamps and intermittent tributaries (off-stream habitat) located on the flood-plain of a west coast Vancouver Island stream (Carnation Creek), as over-wintering habitat, was examined for two winters. All trout (Salmo gairdneri and S_. clarki clarki) and juvenile coho salmon (Oncorhynchus kisutch) off-stream habitat were identified and characterized. Within this habitat: seasonal movement of salmonids was noted, coho growth rates were measured, salmonid populations were enumerated and contribution of off-stream habitat to the total coho smolt production was estimated. Coho and trout did not occupy all winter flooded land. Trout occupied intermittent tributaries, while coho occupied both intermittent tributaries and ephemeral swamps. Salmonid use of flooded meadows was negligible. The contribution of off-stream habitat to the watershed's total smolt production was at least 23% and more than 15% came from sites devoid of water in summer. Seasonal movement of juvenile coho followed a distinct pattern and appeared dependent upon climatic conditions such as magnitude and timing of the first fall (Oct-Nov) freshet. Climatic conditions in spring (March-May) appeared to influence both growth and survival of coho within one small ephemeral swamp.

description: We derive an upper limit for the mixedness of single bosonic mode gaussian states propagating in dissipative channels. It is a function of the initial squeezing and temperature of the channel only. Moreover the time at which von Neumann's entropy reaches its maximum value coincides with that of complete loss of coherence, thus defining a quantum-classical transition.

description: The direct determination of the excitation level density and radiative strength functions of their exciting gamma-transitions is impossible for the larger part of the stable and long-life radioactive target nuclei. This circumstance is uniquely determined by the fact, that the level spacing much less than the resolution of the existing spectrometers of gamma-rays and charged particles. The extraction of these parameters of nucleus in this situation can be executed by their only fitting to the most probable values, reproducing the measured in the nuclear reactions spectra and sections. This inverse problem of mathematical analysis of its nature is principally ambiguous. Moreover, system of equations, those connecting the number of excitable levels and probability of the emission of charge particles are assigned usually within the framework of some assumptions about the mechanism of nuclear reaction and factors, determining the dynamics of the studied process. The verification of these parameters can be partially executed by the calculation of total gamma-spectra for their different sets. As, in particular, the results of this analysis show, the calculation of the structure of the excited levels to a change in the form of the energy dependence of radiative strength functions most likely must be considered to the neutron-binding energy. It is not possible to exclude the possibility of that, that also radiative, and neutron strength functions depend on the structure of neutron resonance and for the higher excitation energies.

description: (abriged)In this paper we study different properties of quasars and their host galaxies at high redshifts up to z~3.4. We compare our results to those of other authors and discuss the correlation between galaxy evolution and quasar activity. We analysed broad-band images in eight filters (from U to K) of eight quasars in the FORS Deep Field with redshifts between z=0.87 and z=3.37. A fully 2-dimensional decomposition was carried out to detect and resolve the host galaxies. We were able to resolve the host galaxies of two out of eight quasars between z=0.87 and z=2.75. Additionally, two host galaxies were possibly resolved. The resolved low-redshift quasar (z=0.9) was identified as a late type galaxy with a moderate star formation rate of 1.8 M_{sun}/yr hosting a supermassive black hole with a mass of <10^{8}M_{sun}. The resolved high redshift host galaxy (z=2.8) shows moderate star formation of 4.4-6.9 M_{sun}/yr, for the black hole mass we found a lower limit of >10^{7}M_{sun}. All quasars host supermassive black hole with masses in the range ~10^{7}-10^{9}M_{sun}. Our findings are well consistent with those of other authors.

It covers some of the major challenges facing scientists and regulatory officials working in agricultural research. These challenges are manifold and complex, and the scientific efforts to meet them are at times inadequate. However, some of the tools to help manage our environment are available, some are being developed and tested, many others have not reached the drawing board. Certainly not all of these tools will work. There is no panacea—no quick solution. It will require a national effort by millions of people working together. It is hoped this report will help you as an individual recognize more fully some of the challenges facing all of us—and thereby involve you in "Managing Our Environment."

description: Quantum digital signatures (QDS) exploit quantum laws to guarantee non-repudiation, unforgeability and transferability of messages with information-theoretic security. Current QDS protocols face two major restrictions, including the requirement of the symmetrization step with additional secure classical channels and quadratic scaling of the signature rate with the probability of detection events. Here, we present an efficient QDS protocol to overcome these issues by utilizing the classical post-processing operation called post-matching method. Our protocol does not need the symmetrization step, and the signature rate scales linearly with the probability of detection events. Simulation results show that the signature rate is three orders of magnitude higher than the original protocol in a 100-km-long fiber. This protocol is compatible with existing quantum communication infrastructure, therefore we anticipate that it will play a significant role in providing digital signatures with unconditional security.

description: The model-free analysis of experimental data in the intensities of two-step cascades into 163Dy shows, that the basically special features of the cascade gamma-decay of its compound-state completely correspond to those observed in other nuclei. Thus, the density of the levels in this nucleus with good precision it is reproduced as sum of three, five, seven-quasiparticle excitations with the tenfold, as the minimum, by an increase due to vibration type excitations. The greatest changes in the sum of the radiation strength functions of dipole primary gamma-transitions correlate with a change in the number of excitable quasi-particles. Accordingly, model presentations about the radiation strength functions of larger, than for those existing, accuracy must consider as a quantity of excited quasi-particles, so the presence of the vibration type excitations of all possible types. Moreover, the reliable picture of the studied process can be obtained only from the approximation of the distributions of the intensities of cascades in the function of energies of their primary gamma-transitions.

description: Coronaviruses have been a source of significant risk to global health. Almost four million lives have been lost to SARS-CoV-2 (COVID-19). Major efforts are ongoing to mitigate the current pandemic and future outbreaks by designing broad-spectrum drugs to target coronaviruses across species. We identified the positions of residues that participate in binding by using the 3D visualization tool Mol* (https://molstar.org/) to view known inhibitors interacting with the active site of SARS-CoV-2 proteases, two essential enzymes to virus maturation. Experimental structures from the Protein Data Bank (PDB) were used where available and additional models were generated using Robetta (https://robetta.bakerlab.org/). Sequences for additional coronaviridae proteases were obtained from NCBI (https://blast.ncbi.nlm.nih.gov/Blast.cgi). A sequence-based comparison was performed using Clustal (https://www.ebi.ac.uk/Tools/msa/clustalo/) and a structure-based comparison was performed using Dali (http://ekhidna2.biocenter.helsinki.fi/dali/), both using SARS-CoV-2 as the template. The preliminary results show some positions with mutations that remain within the same amino acid classification, groupings by structural, chemical, and functional similarity. Other mutations result in a different classification in that position that may have a significant impact on the active site structure and binding. We will continue to analyze these changes to identify patterns in the mutations and to identify which mutations have the most impact and are most relevant to potential viral evasion of broad-spectrum drugs.

description: Do white dwarfs have inner cores made of iron? Neutron rich nuclei like $^{56}$Fe experience a net gravitational force and sediment toward the core. Using new phase diagrams and molecular dynamics simulations, we show that $^{56}$Fe should separate into mesoscopic Fe-rich crystallites due to its large charge relative to the background. At solar abundances, these crystallites rapidly precipitate and form an inner core of order 100 km and $10^{-3} M_\odot$ that may be detectable with asteroseismology. Associated cooling delays could be up to a Gyr for low mass white dwarfs but are only $\sim$0.1 Gyr for massive white dwarfs, so while this mechanism may contribute to the Q-branch the heating is insufficient to fully explain it.

description: Strain induced by a magnetic field is a common phenomenon for ferromagnets, but few antiferromagnets show large strain induced by a magnetic field. On the basis of linear strain measurements of sintered samples of triangular antiferromagnet ACrS2 (A = Cu, Ag, and Au) in magnetic fields up to 9 T, the AgCrS2 sample was found to show a large strain, yielding a large volume change over 700 ppm, which is one of the largest volume changes measured to date for an antiferromagnet. This large strain appeared only at the Néel temperature of 42 K and was not restored to its initial state when the applied magnetic field was decreased to zero; however, it was initialized by cooling the sample to far below the Néel temperature. These results suggest that the coexistence of magnetically ordered and paramagnetic phases at the first-order phase transition plays an important role. AuCrS2 showed a magnetic-field-induced strain with similar features, although it was smaller than that in AgCrS2.

description: Classical Cepheids (DCEPs) are the most important primary indicators of the extragalactic distance scale. Establishing the dependence on metallicity of their period--luminosity and period--Wesenheit ($PLZ$/$PWZ$) relations has deep consequences on the calibration of secondary distance indicators that lead to the final estimate of the Hubble constant (H$_0$). We collected high-resolution spectroscopy for 47 DCEPs plus 1 BL Her variables with HARPS-N@TNG and derived accurate atmospheric parameters, radial velocities and metal abundances. We measured spectral lines for 29 species and characterized their chemical abundances, finding very good agreement with previous results. We re-determined the ephemerides for the program stars and measured their intensity-averaged magnitudes in the $V,I,J,H,K_s$ bands. We complemented our sample with literature data and used the Gaia Early Data Release 3 (EDR3) to investigate the $PLZ$/$PWZ$ relations for Galactic DCEPs in a variety of filter combinations. We find that the solution without any metallicity term is ruled out at more than the 5 $σ$ level. Our best estimate for the metallicity dependence of the intercept of the $PLK_s$, $PWJK_s$, $PWVK_s$ and $PWHVI$ relations with three parameters, is $-0.456\pm$0.099, $-0.465\pm$0.071, $-0.459\pm$0.107 and $-0.366\pm$0.089 mag/dex, respectively. These values are significantly larger than the recent literature. The present data are still inconclusive to establish whether or not also the slope of the relevant relationships depends on metallicity. Applying a correction to the standard zero point offset of the Gaia parallaxes has the same effect of reducing by $\sim$22\% the size of the metallicity dependence on the intercept of the PLZ/PWZ relations.

description: A high finesse optical cavity can be used to search for cosmic axions in the mass range 10^{-6}< m_a <10^{-4} eV. Either a two-arm or a single-arm cavity is suitable and in either case the signal as resonant sidebands imposed on the carrier. Assuming for the local axion density the usual figure of 500 MeV/cm^3 [8], the KSVZ axion line [4] g/m_a = 0.4 Gev^{-2}, can be reached over the full mass range in a one year search.

description: Granular particles vibrated in a fluid have been found to exhibit self-organization with attractive and repulsive interactions between the particles. These interactions have been attributed to the steady streaming flow around oscillating particles. Here we examine the steady streaming flow surrounding a vertically oscillating sphere using three dimensional particle tracking velocimetry. We present measurements of the flow with the sphere far from boundaries, close to the bottom wall of the tank, and near another oscillating sphere. The steady velocity field is found to disagree with available analytic calculations. When the sphere is oscillated near the bottom wall the entire topology of the flow changes, resulting in a larger repulsive region than expected. Previous experiments saw attraction between particles in the region where the flow around a single particle is repulsive. We conclude that advection in the streaming flow due to a single particle cannot explain the observed attractive and repulsive interactions, rather non-linear interactions between the flows around two or more spheres must be responsible.

description: Electrically generated spin accumulation due to the spin Hall effect is imaged in n-GaAs channels using Kerr rotation microscopy, focusing on its spatial distribution and time-averaged behavior in a magnetic field. Spatially-resolved imaging reveals that spin accumulation observed in transverse arms develops due to longitudinal drift of spin polarization produced at the sample boundaries. One- and two-dimensional drift-diffusion modeling is used to explain these features, providing a more complete understanding of observations of spin accumulation and the spin Hall effect.

description: Quantum many-body scars (QMBS) constitute a new quantum dynamical regime in which rare "scarred" eigenstates mediate weak ergodicity breaking. One open question is to understand the most general setting in which these states arise. In this work, we develop a generic construction that embeds a new class of QMBS, rainbow scars, into the spectrum of an arbitrary Hamiltonian. Unlike other examples of QMBS, rainbow scars display extensive bipartite entanglement entropy while retaining a simple entanglement structure. Specifically, the entanglement scaling is volume-law for a random bipartition, while scaling for a fine-tuned bipartition is sub-extensive. When internal symmetries are present, the construction leads to multiple, and even towers of rainbow scars revealed through distinctive non-thermal dynamics. Remarkably, certain symmetries can lead rainbow scars to arise in translation-invariant models. To this end, we provide an experimental road map for realizing rainbow scar states in a Rydberg-atom quantum simulator, leading to coherent oscillations distinct from the strictly sub-volume-law QMBS previously realized in the same system.

description: Short thermalization times of less than 1 fm/c for quark and gluon matter have been suggested by recent experiments at the Relativistic Heavy Ion Collider (RHIC). It has been difficult to justify this rapid thermalization in first-principle calculations based on perturbation theory or the color glass condensate picture. Here, we address the related question of the decoherence of the gluon field, which is a necessary component of thermalization. We present a simplified leading-order computation of the decoherence time of a gluon ensemble subject to an incoming flux of Weizsacker-Williams gluons. We also discuss the entropy produced during the decoherence process and its relation to the entropy in the final state which has been measured experimentally.

description: We theoretically show that a two-band system with very different masses harbors a resonant pair scattering that leads to novel pairing properties, as highlighted by the Bardeen-Cooper-Schrieffer (BCS) to Bose-Einstein condensation (BEC) crossover. Most importantly, the interband pair-exchange coupling induces an effective intraband attraction in each band, enhancing the superfluidity/superconductivity. The effect, a kind of Suhl-Kondo mechanism, is specifically enhanced when the second band has a heavy mass and is incipient (lying close to, but just above, the chemical potential, $μ$), which we call a resonant pair scattering. By elucidating the dependence of the effective interactions and gap functions on $μ$, we can draw an analogy between the resonant pair scattering and the Feshbach resonance.

Container nursery methods for producing seedlings of chinese pine (Pinus tabulaeformis Carr.) and oriental arborvitae (Thuja orientalis (L.) Franco)

description: An experiment was conducted to determine the suitability of nine types of plastic or paper containers for raising planting stock of Chinese pine (Pinus tabul aeformis Carr.) and oriental arborvitae (Thuja orientalis (L.) Franco). Plants were grown on the campus of the University of British Columbia, initially, in an unheated plastic shelter and later in a shade house. Height, root-collar diameter and dry weight measurements were taken 22 weeks after germination. Results showed that dry matter production per unit area increased as container spacing decreased. However, the dry weight of individual plants increased with increase in both the volume and spacing of containers. Shoot/root and height/root-collar diameter ratios decreased with increase in container spacing. A controlled experiment, in which plant density was varied independently of container volume, showed that with closer seedling density shoot height increased, but root-collar diameter decreased. In P. tabul aeformi s but not T. orientalis, there was a significant negative relationship between seedling density and whole plant dry weight. A controlled experiment in which container volume was varied independently of plant spacing showed a significant positive relationship between container volume and total plant dry weight in both species. Comparison of three mineral nutrient regimes indicated that elevation of phosphorus level at the beginning and end of the growing season did not increase seedling dry matter production. Growth was better when nitrogen was supplied at 100 ppm, than at 250 ppm. Lateral roots of both species were prevented from growing down or around the container wall by painting the inside of the containers with acrylic latex paint containing cupric carbonate. The chemically-inhibited roots were able to resume elongating after the seedlings were transplanted from the containers. Thus, after transplanting, the primary lateral roots of the chemically root-pruned plants extended straight out from the tap root. In contrast, the primary roots of plants from unpainted containers grew mainly from the lower end of the root plug where they were air-pruned after growing down the container wall. In trials with kraft paper containers, the paper disintegrated before the end of the growing season. Thus roots of adjacent seedlings became intermeshed and were difficult to separate. This was prevented either by using polyethylene coated kraft paper, pr by impregnating the paper with copper sulfide. Lateral roots of seedlings raised in copper sulfide impregnated paper containers were pruned as efficiently as those of seedlings grown in copper-painted plasic containers, yet retained the capacity to resume elongation after transplanting.

description: We study effects of tilted magnetic fields on energy levels in a double-quantum-well (DQW) system, focusing on the coupling of subbands and Landau levels (LLs). The subband-LL coupling induces anticrossings between LLs, manifested directly in the magnetoresistance. The anticrossing gap becomes larger than the spin splitting at the tilting angle $θ\sim 20^\circ $ and larger than the cyclotron energy at $θ\sim 50^\circ $, demonstrating that the subband-LL coupling exerts a strong influence on quantum Hall states even in at a relatively small $θ$ and plays a dominant role for larger $θ$. We also find that when the DQW potential is asymmetric, LL coupling occurs even within a subband. Calculations including higher-order coupling reproduce the experimental results quantitatively well.
