description: We propose a realization of a charge parity meter based on two double quantum dots alongside a quantum point contact. Such a device is a specific example of the general class of mesoscopic quadratic quantum measurement detectors previously investigated by Mao et al. [Phys. Rev. Lett. 93, 056803 (2004)]. Our setup accomplishes entangled state preparation by a current measurement alone, and allows the qubits to be effectively decoupled by pinching off the parity meter. Two applications of the parity meter are discussed: the measurement of Bell's inequality in charge qubits and the realization of a controlled NOT gate.

description: The study of neutrinoless double beta decay is of outmost importance for neutrino physics. It is considered to be the gold plated channel to probe the fundamental character of neutrinos and to determine the neutrino mass. From the experimental point about nine different isotopes are explored for the search. After a general introduction follows a short discussion on nuclear matrix element calculations and supportive measurements. The current experimental status of double beta searches is presented followed by a short discussion of the ideas and proposals for large scale experiments.

description: Andean potato cultivars, a staple crop for diets and agriculture in the Andes, are declining largely due to lack of public interest and consumer demand, posing socio-economic and environmental challenges. Potato is native to the South American Andes, where farmers have, for millennia, selected thousands of cultivars for specific traits. This study aimed to explore and identify potential strategy options to increase the cultivation and preservation of Andean potato cultivars in Ecuador. This qualitative research consisted of semi-structured interviews with Andean farmers in the province of Chimborazo to identify farmers’ key challenges, and a document analysis co-developed with local experts to identify key strategies that target public interest in Andean potato cultivars. Twelve strategy options were preliminarily identified and narrowed down to the six most applicable options, having added socio-economic and environmental benefits, and that could be implemented in Ecuador to incentivize cultivation and preservation Andean potato cultivars.

description: A quantum graph model for a single sheet of graphene is extended to bilayer and trilayer Bernal-stacked graphene; the spectra are characterized and the dispersion relations explicitly obtained; Dirac cones are then proven to be present only for trilayer graphene, although the bilayer has a gapless parabolic band component. Our model rigorously exhibits basic facts from tight-binding calculations, effective two-dimensional models and a $π$-orbital continuum model with nearest-neighbour tunneling that have been discussed in the physics literature.

description: We present sets of equation of state (EOS) of nuclear matter including hyperons using an SU_f(3) extended relativistic mean field (RMF) model with a wide coverage of density, temperature, and charge fraction for numerical simulations of core collapse supernovae. Coupling constants of Sigma and Xi hyperons with the sigma meson are determined to fit the hyperon potential depths in nuclear matter, U_Sigma(rho_0) ~ +30 MeV and U_Xi(rho_0) ~ -15 MeV, which are suggested from recent analyses of hyperon production reactions. At low densities, the EOS of uniform matter is connected with the EOS by Shen et al., in which formation of finite nuclei is included in the Thomas-Fermi approximation. In the present EOS, the maximum mass of neutron stars decreases from 2.17 M_sun (Ne mu) to 1.63 M_sun (NYe mu) when hyperons are included. In a spherical, adiabatic collapse of a 15$M_\odot$ star by the hydrodynamics without neutrino transfer, hyperon effects are found to be small, since the temperature and density do not reach the region of hyperon mixture, where the hyperon fraction is above 1 % (T > 40 MeV or rho_B > 0.4 fm^{-3}).

description: Cellulose nanocrystals (CNC) can be considered as model colloidal rods and have practical applications in the formation of soft materials with tailored anisotropy. Here, we employ two contrasting microfluidic devices to quantitatively elucidate the role of shearing and extensional flows on the alignment of a dilute CNC dispersion. Characterization of the flow field by micro-particle image velocimetry is coupled to flow-induced birefringence analysis to quantify the deformation rate--alignment relationship. The deformation rate required for CNC alignment is 4$\times$ smaller in extension than in shear. Alignment in extension is independent of the deformation rate magnitude, but is either 0$^\circ$ or 90$^\circ$ to the flow, depending on its sign. In shear flow the colloidal rods orientate progressively towards 0$^\circ$ as the deformation rate magnitude increases. Our results decouple the effects of shearing and extensional kinematics at aligning colloidal rods, establishing coherent guidelines for the manufacture of structured soft materials.

description: We present a detailed analysis of the new planetary nebula (PN) IPHASX J193718.6+202102 using deep imaging and intermediate- and high resolution spectroscopy that are interpreted through morpho-kinematic and photoionisation modelling. The physical structure of the nebula consists of a fragmented torus and an extremely faint orthogonal bipolar outflow, contrary to the pinched waist PN morphology suggested by its optical image. Our kinematic analysis indicates that the torus is expanding at 25$\pm$5 km s$^{-1}$ and is gradually breaking up. At an estimated distance of 7.1$_{-0.3}^{+0.8}$ kpc, the corresponding kinematic age of $\sim$26000 years is consistent with a faint and disintegrating PN. The intermediate-resolution spectra reveal an excited PN with chemical abundances typical of Type II PNe. Based on the latter we also estimate an initial mass for the progenitor in the range 2--3 M$_{\odot}$ and a central star (CSPN) mass $M_\mathrm{CSPN}\sim$0.61 M$_{\odot}$. The Spitzer MIPS 24 $μ$m emission that closely follows the fragmented torus could be attributed to the emission of [O IV] at 25.9 $μ$m rather than to dust emission. All the results coherently point towards an evolved moderately massive bipolar Type II PN on the brink of dissolving into the interstellar medium.

description: We present a new method for the quantization of totally constrained systems including general relativity. The method consists in constructing discretized theories that have a well defined and controlled continuum limit. The discrete theories are constraint-free and can be readily quantized. This provides a framework where one can introduce a relational notion of time and that nevertheless approximates in a well defined fashion the theory of interest. The method is equivalent to the group averaging procedure for many systems where the latter makes sense and provides a generalization otherwise. In the continuum limit it can be shown to contain, under certain assumptions, the ``master constraint'' of the ``Phoenix project''. It also provides a correspondence principle with the classical theory that does not require to consider the semiclassical limit.

description: We present a clean, magnitude-limited (IRAC1 or WISE1$\leq$15.0 mag) multiwavelength source catalog for the LMC. The catalog was built upon crossmatching ($1''$) and deblending ($3''$) between the SEIP source list and Gaia DR2, with strict constraints on the Gaia astrometric solution to remove the foreground contamination. The catalog contains 197,004 targets in 52 different bands including 2 ultraviolet, 21 optical, and 29 infrared bands. Additional information about radial velocities and spectral/photometric classifications were collected from the literature. The bright end of our sample is mostly comprised of blue helium-burning stars (BHeBs) and red HeBs with inevitable contamination of main sequence stars at the blue end. After applying modified magnitude and color cuts based on previous studies, we identify and rank 2,974 RSG, 508 YSG, and 4,786 BSG candidates in the LMC in six CMDs. The comparison between the CMDs of the LMC and SMC indicates that the most distinct difference appears at the bright red end of the optical and near-infrared CMDs, where the cool evolved stars (e.g., RSGs, AGB, and RGs) are located, which is likely due to the effect of metallicity and SFH. Further quantitative comparison of colors of massive star candidates in equal absolute magnitude bins suggests that, there is basically no difference for the BSG candidates, but large discrepancy for the RSG candidates as LMC targets are redder than the SMC ones, which may be due to the combined effect of metallicity on both spectral type and mass-loss rate, and also the age effect. The $T_{\rm eff}$ of massive star populations are also derived from reddening-free color of $(J-K_{\rm S})_0$. The $T_{\rm eff}$ ranges are $35008000$ K for BSG population, with larger uncertainties towards the hotter stars.

description: Herein, we analyze an efficient branching particle method for asymptotic solutions to a class of continuous-discrete filtering problems. Suppose that $t\to X_t$ is a Markov process and we wish to calculate the measure-valued process $t\toμ_t(\cdot)\doteq P\{X_t\in \cdot|σ\{Y_{t_k}, t_k\leq t\}\}$, where $t_k=kε$ and $Y_{t_k}$ is a distorted, corrupted, partial observation of $X_{t_k}$. Then, one constructs a particle system with observation-dependent branching and $n$ initial particles whose empirical measure at time $t$, $μ_t^n$, closely approximates $μ_t$. Each particle evolves independently of the other particles according to the law of the signal between observation times $t_k$, and branches with small probability at an observation time. For filtering problems where $ε$ is very small, using the algorithm considered in this paper requires far fewer computations than other algorithms that branch or interact all particles regardless of the value of $ε$. We analyze the algorithm on Lévy-stable signals and give rates of convergence for $E^{1/2}\{\|μ^n_t-μ_t\|_γ^2\}$, where $\Vert\cdot\Vert_γ$ is a Sobolev norm, as well as related convergence results.

description: Problem Studied:  The numbers of overweight people in the United States have more than doubled since the 1980's.  According to the National Health and Nutrition Examination Survey (NHANES), the percentage of overweight and obese Americans between the ages of 20 and 74 has increased from 15% of the population in 1980 to 32.9% of the population in 2004.  This trend seems to hold true for children and adolescents, as well.  In 2004, 17.1% of U.S. children and adolescents were overweight (Ogden, et al., 2004).  Among these, Hispanic children and adolescents had the highest rates of being overweight.  According to a recent study 38.2% of Hispanic children and adolescent aged 2 to 19 are overweight or obese (Ogden, et.al. 2010). Compared to their normal weight counterparts, overweight or obese children and adolescents have higher risks for developing high blood pressure, sleep apnea, and type 2 diabetes in addition to psychological problems associated with alienation, eating disorders, mental health problems, and discrimination.  These conditions can be expensive to treat and manage.  However, perhaps the most important consequence of childhood obesity is that children do not simply outgrow the weight, and they are more likely to grow up to be overweight adults if the weight problem is not addressed at a younger age. Researchers have been studying causes and consequences of overweight and obesity during childhood and adulthood as well as ways to alter or improve childhood overweight trends in the U.S.  It is possible that greater access to health care, including health insurance coverage and access to a usual source of care (i.e. periodic well child visits) can improve this problem.  However, to date, research in the possible causal relationship between health insurance status and the use of a usual source of care and childhood overweight is limited.  Results:  Based on the results from previous studies, we divided our study population into three different age groups (2-6 yrs., 7-11 yrs., and 12-17 yrs.) and estimated the effects for each age group separately.  The overall results indicate that USC and health insurance coverage was not endogenous in the overweight and obesity outcomes of lower income children and adolescents.  Our LPM and probit results showed that CHIP eligibility significantly reduced the overweight and obesity probabilities of 2-6 year old Hispanic children, excepting those at the lowest income levels.  In contrast to the results for the youngest age group, we did not see a significant reduction in overweight or obesity probabilities of lower income 7-11 year old children or adolescents.  Although among adolescents CHIP eligibility had no significant effects on overweight and obesity outcomes, the LPM results indicate that CHIP eligibility significantly increased the health insurance coverage for non-Hispanic adolescents.

description: The first essay uses spatially and temporally referenced data and spatial econometric techniques to determine how different types of developed land uses (low-density, medium-density, and high-density) affect stream ecosystem health and which measure of urbanization (total development, disaggregated development categories, or impervious surface cover [ISC]) captures more variation in ecosystem health measures.  While all three measures of urbanization illustrates a strong association between up-stream development and the condition of the stream ecosystem, our study found that ISC might offer the better measure of urbanization's impact on the stream.  Our results were robust to alternative measures of stream biotic conditions. The second essay complements the existing literature on the effects of ISC on stream health and water quality by examining the link between various development regulations, including parcel-level ISC limits and clustering requirements, and the amount of ISC.  Our results found, using parcel-level data and regression analysis that higher-density development generates less ISC and requires the conversion of less undeveloped land than low-density development and clustered subdivisions have less total ISC than traditional subdivisions, although the result may not be practically significant. We also found that when examined at scales larger than the individual parcel, such as the subdivision, low density zoning and parcel-level ISC limits may actually lead to increases in overall ISC as well as the amount of land converted to development.   Clustered developments have been put forth as one mechanism to reduce the environmental impacts of development, however, the economics of clustered subdivisions are not well understood.   The final essay examines the link between the type of residential development (clustered versus traditional subdivisions) and house price and appreciation rates.  We find the coefficient on the variable indicating whether the house was located in a clustered subdivision to be positive, but not statistically significant.  In addition, our results suggest, after controlling for house characteristics, houses located in traditional and clustered subdivisions followed a similar price path between 1983 and 2009, with the difference between the two subdivision types not statistically or practically significant.

description: This study examines the non- medical, or recreational use, of prescription drugs among  undergraduate students. Research conducted at University of Maryland, Baltimore  County attempts to answer several research questions regarding the non- medical use of  prescription medications. First, significant differences in the classifications of  prescription drugs that are used for non- medical reasons will be examined. Demographic  differences among various race and ethnic groups will also be explored in addition to  differences between the gender, age, declared major and academic class standing in the  non- medical use of prescription drugs. Lastly, the sources that provide undergraduate  college students with the prescription drugs for non- medical use will be examined along  with the reasons for such recreational use. Data are collected through self- administered  surveys taken in classes across an array of disciplines across campus. Surveys are  administered to all students within the selected classes as a method of reducing non-respondent  bias.

description: The present study seeks to fill a gap within the literature pertaining to the formal and informal job search methods utilized by college-educated African Americans. An online survey was administered to members of Black alumni groups at various universities, and referral sampling followed. Statistics were computed on responses to closed-ended items using SPSS, and thematic analysis was used to analyze results of open-ended items. Sending out r?sum?s was the job search method most utilized among both employed and unemployed respondents, however leveraging personal relationships was the job search method with the highest reported success rate among those currently employed. Over half (56.6%) of employed respondents reported that they received assistance from a personal contact in the process of obtaining their current jobs. Utilizing the help of family, friends, professors and acquaintances in the job search process is the most effective form of job search for college-educated African Americans.

description: We employ transformation optics to study analytically nonlinear wave mixing from a singular geometry of touching plasmonic wires. We obtain the analytic solution of the near-field and complement it with a solution of the far-field properties. We find, somewhat surprisingly, that optimal efficiency (in both regimes) is obtained for the degenerate case of the Second-harmonic generation. We exploit the analytic solution obtained to trace this behaviour to the spatial overlap of the input fields near the geometric singularity.

description: Fractal geometry of random curves appearing in the scaling limit of critical two-dimensional statistical systems is characterized by their harmonic measure and winding angle. The former is the measure of the jaggedness of the curves while the latter quantifies their tendency to form logarithmic spirals. We show how these characteristics are related to local operators of conformal field theory and how they can be computed using conformal invariance of critical systems with central charge $c \leqslant 1$.

description: In order to investigate how an integration centered ideology of a planned community  influenced interracial contact among adolescents in its high schools, this study  examined whether the racial composition of sports teams and extracurricular groups  in a high school located in a planned community were more diverse than those in a  high school located in an unplanned community. Multiple yearbooks were used to  investigate if patterns changed over time. The high school located in the planned  community revealed higher rates of minority representation among these groups in 11  of 16 ratio comparisons. As the minority enrollment in the schools increased over  time, rates of minority representation among groups increased in the high school  located in the planned community and decreased in the high school located in the  unplanned community. Living in a planned community may have a positive effect on  interracial mixing among teams and organizations within a high school.

description: The widespread adoption of Competency-Based Medical Education (CBME) has resulted in a more explicit focus on learners’ abilities to effectively demonstrate achievement of the competencies required for safe and unsupervised practice. While CBME implementation has yielded many benefits, by focusing explicitly on what learners are doing, curricula may be unintentionally overlooking who learners are becoming (i.e., the formation of their professional identities). Integrating professional identity formation (PIF) into curricula has the potential to positively influence professionalism, well-being, and inclusivity; however, issues related to the definition, assessment, and operationalization of PIF have made it difficult to embed this curricular imperative into CBME. This paper aims to outline a path towards the reconciliation of PIF and CBME to better support the development of physicians that are best suited to meet the needs of society. To begin to reconcile CBME and PIF, this paper defines three contradictions that must and can be resolved, namely: (1) CBME attends to behavioral outcomes whereas PIF attends to developmental processes; (2) CBME emphasizes standardization whereas PIF emphasizes individualization; (3) CBME organizes assessment around observed competence whereas the assessment of PIF is inherently more holistic. Subsequently, the authors identify curricular opportunities to address these contradictions, such as incorporating process-based outcomes into curricula, recognizing the individualized and contextualized nature of competence, and incorporating guided self-assessment into coaching and mentorship programs. In addition, the authors highlight future research directions related to each contradiction with the goal of reconciling ‘doing’ and ‘being’ in medical education.
Gay Male Intimate Partner Violence: Prevalence Measures and a New Theoretical Model

description: Intimate partner violence is difficult to measure and assess in heterosexual couples given the high levels of social and personal stigma associated with being a victim of the violence. This issue is made more difficult when such violence occurs in gay male couples. Hidden even from their own community, gay victims of domestic violence struggle to receive help and treatment for their abuse. A major purpose of this paper is to highlight issues associated with intimate partner violence through a comprehensive literature review. A second purpose of this research is to obtain another indicator of the prevalence of gay male intimate partner violence. This was accomplished by constructing three scales of abuse types. In addition to providing researchers and other professionals with theoretical and health considerations about the intimate partner violence problem for gay men, it includes validation for these measures. Similar to interpersonal violence for heterosexual couples there were significant correlations among the three types of abuse experienced (physical, psychological and sexual). The thesis concludes with recommendations for future research and programs needed for this population.

We find that the power factor of Ta2PdX6 is relatively high from middle-low to room temperatures, and notably Ta2PdSe6 shows the largest power factor among thermoelectric materials with an electrical conductivity of 10-2 Ωcm at 300 K. Ta2PdS6 will be a possible candidate for a Peltier cooling material if the lattice thermal conductivity is reduced by chemical substitution.

description: This article compares the Ks magnitude distribution of Small Magellanic Cloud asymptotic giant branch stars obtained from the DENIS and 2MASS data with theoretical distributions. Theoretical Ks magnitude distributions have been constructed using up-to-date stellar evolution calculations for low and intermediate-mass stars, and in particular for thermally pulsing asymptotic giant branch stars. Separate fits of the magnitude distributions of carbon- and oxygen-rich stars allowed us to constrain the metallicity distribution across the galaxy and its star formation rate. The Small Magellanic Cloud stellar population is found to be on average 7-9 Gyr old but older stars are present at its periphery and younger stars are present in the direction of the companion galaxy the Large Magellanic Cloud. The metallicity distribution traces a ring-like structure that is more metal rich than the inner region of the galaxy. The C/M ratio discussed in Paper I is a tracer of the metallicity distribution only if the underlying stellar population is of intermediate-age.

description: Terrorism poses a major threat to nations around the world in terms of its negative consequences.  State policies to curb terrorism have become a central item in government agendas. Turkey has had a prolonged problem with terrorist violence, predominantly the Kurdistan Workers' Party (PKK) that has resulted in approximately 35,000 fatalities. To thwart PKK violence, Turkey has implemented diversified policies, including those that are deterrence, anti-defiance and accommodative in nature. The main purpose of this research was to examine Turkish Government's policies during the PKK violence (1984-2007), and to analyze the effects of these policies in reducing PKK violence. Using quantitative and qualitative techniques on various large-scale datasets, I conducted descriptive and statistical (VAR) analyses to address the problem. Based on these analyses, I found that, despite the deterrent effect of certain policies in the mid-run, none had a sustainable deterrent impact on the PKK violence (in the entire span). I also found that incapacitating PKK members had a statistically significant counterproductive impact on PKK-initiated violence for a three month period. I also examined the PKK's internal dynamics and identified the relationship between the PKK's strategic moves and its use of violence. I found that the level and other aspects (i.e., form, purpose, location, and target status) of PKK violence were directly related to the PKK's strategic decisions, rather than to government policies. I found, however, that the PKK's evolution in different strategies has been as a result of government's deterrence policies that defeated and forced the PKK to readjust its goals and strategies over the time. However, these policies are highly likely to be perceived illegitimate and have the nature to increase anti-governmental hostility, in turn, to increase the support level from Turkey's Kurdish society to the PKK (keeping its viability). Results also indicated that despite its militarily defeat and limited flexibility, the PKK's ability to initiate violent incidents did not end. Results from the entire analysis revealed that despite PKK's militarily defeat, deterrence policies are ineffective in eliminating PKK violence entirely in the long term even if certain policies reduce the violence level in the mid-term.

description: We develop a theory of double clubs which extends Kelly's theory of clubs to the pseudo double categories of Pare and Grandis. We then show that the club for symmetric strict monoidal categories on Cat extends to a `double club' on the pseudo double category of `categories, functors, profunctors and transformations'.

description: Detecting quality in large unstructured datasets requires capacities far beyond the limits of human perception and communicability and, as a result, there is an emerging trend towards increasingly complex analytic solutions in data science to cope with this problem. This new trend towards analytic complexity represents a severe challenge for the principle of parsimony or Occams Razor in science. This review article combines insight from various domains such as physics, computational science, data engineering, and cognitive science to review the specific properties of big data. Problems for detecting data quality without losing the principle of parsimony are then highlighted on the basis of specific examples. Computational building block approaches for data clustering can help to deal with large unstructured datasets in minimized computation time, and meaning can be extracted rapidly from large sets of unstructured image or video data parsimoniously through relatively simple unsupervised machine learning algorithms. Why we still massively lack in expertise for exploiting big data wisely to extract relevant information for specific tasks, recognize patterns, generate new information, or store and further process large amounts of sensor data is then reviewed; examples illustrating why we need subjective views and pragmatic methods to analyze big data contents are brought forward. The review concludes on how cultural differences between East and West are likely to affect the course of big data analytics, and the development of increasingly autonomous artificial intelligence aimed at coping with the big data deluge in the near future.

description: Terahertz (THz) communications are regarded as a pillar technology for the sixth generation (6G) wireless systems, by offering multi-ten-GHz bandwidth. To overcome the short transmission distance and huge propagation loss, ultra-massive (UM) MIMO systems that employ sub-millimeter wavelength antennas array are proposed to enable an enticingly high array gain. In the UM-MIMO systems, hybrid beamforming stands out for its great potential in promisingly high data rate and reduced power consumption. In this paper, challenges and features of the THz hybrid beamforming design are investigated, in light of the distinctive THz peculiarities. Specifically, we demonstrate that the spatial degree-of-freedom (SDoF) is less than 5, which is caused by the extreme sparsity of the THz channel. The blockage problem caused by the huge reflection and scattering losses, as high as 15 dB or over, is studied. Moreover, we analyze the challenges led by the array containing 1024 or more antennas, including the requirement for intelligent subarray architecture, strict energy efficiency, and propagation characterization based on spherical-wave propagation mechanisms. Owning up to hundreds of GHz bandwidth, beam squint effect could cause over 5~dB array gain loss, when the fractional bandwidth exceeds 10%. Inspired by these facts, three novel THz-specific hybrid beamforming architectures are presented, including widely-spaced multi-subarray, dynamic array-of-subarrays, and true-time-delay-based architectures. We also demonstrate the potential data rate, power consumption, and array gain capabilities for THz communications. As a roadmap of THz hybrid beamforming design, multiple open problems and potential research directions are elaborated.

description: The partial eruption of a filament channel with bifurcated substructures is investigated using datasets obtained from both ground-based and space-borne facilities. Small-scale flux reconnection/cancellation events in the region triggered the pile-up of ambient magnetic field, observed as bright EUV loops in close proximity of the filament channel. This led to the formation of a V-shaped cusp structure at the site of interaction between the coalesced EUV loops and the filament channel, with the presence of distinct plasmoid structures and associated bidirectional flows. Analysis of imaging data from SDO/AIA further suggests the vertical split of the filament structure into two substructures. The perturbed upper branch of the filament structure rose up and erupted with the onset of an energetic GOES M1.4 flare at 04:30 UT on January 28, 2015. The estimated twist number and squashing factor obtained from nonlinear force free-field extrapolation of the magnetic field data support the vertical split in filament structure with high twist in upper substructure. The loss in equilibrium of the upper branch due to torus instability, implying this as a potential triggering mechanism of the observed partial eruption.

description: Statefinder diagnostic is a useful method which can differ one dark energy model from the others. The Statefinder pair $\{r, s\}$ is algebraically related to the equation of state of dark energy and its first time derivative. We apply in this paper this method to the dilaton dark energy model based on Weyl-Scaled induced gravitational theory. We investigate the effect of the coupling between matter and dilaton when the potential of dilaton field is taken as the Mexican hat form. We find that the evolving trajectory of our model in the $r-s$ diagram is quite different from those of other dark energy models.

description: We consider bounds on codes in spherical caps and related problems in geometry and coding theory. An extension of the Delsarte method is presented that relates upper bounds on the size of spherical codes to upper bounds on codes in caps. Several new upper bounds on codes in caps are derived. Applications of these bounds to estimates of the kissing numbers and one-sided kissing numbers are considered. It is proved that the maximum size of codes in spherical caps for large dimensions is determined by the maximum size of spherical codes, so these problems are asymptotically equivalent.

The mountain pine beetle (Dendroctonus ponderosae Hopkins) (Coleoptera: Curculionidae) is a significant destructive force in the pine forests of western Canada and has the capacity to spread east into a novel host tree species, jack pine (Pinaceae).
New populations have been documented in central Alberta, Canada, but the source populations for these outbreaks have yet to be identified. In this study we use genetic data to identify parent populations for recent outbreak sites near Slave Lake, Lac La Biche, and Hinton, Alberta. We found the northern population cluster that entered Alberta near Grande Prairie was the source of the most eastern established population near Lac La Biche, and the range expansion to this leading-edge population has been too rapid to establish evidence of population structure. However, some dispersal from a population in the Jasper and Hinton area has been detected as far north and east as Slave Lake, Alberta. We also identified two potential source populations for the current outbreak in Hinton: most beetles appear to be from Jasper National Park, Alberta, but some also originated from the northern population cluster. These findings demonstrate the dynamic dispersal capabilities of mountain pine beetle across the Alberta landscape and the potential hazard of increased dispersal to newly established
leading-edge populations.

description: It is argued that not only the blue (at the brightness maximum) but also the red (in the slow decay phase) components of the optical continuum of powerful flares on dMe stars are formed near the photosphere. The possible appearance of HeI lines in the relaxation zones for the plasma to a state of thermal equilibrium (as a result of a rise in electron temperature owing to elastic collisions of electrons with atoms and ions) is noted (for sufficiently high speeds of a non-stationary chromospheric shock wave propagating toward the photosphere of the Sun and stars). A scheme is proposed for the positioning of the "layers" of plasma responsible for the generation of radiation in the white light continuum during the impulsive phase of powerful stellar flares.
