description: In this paper, we improve the previous work on the MHD Alfven wave oscillation model for the neutron star (NS) kHz quasi-periodic oscillations (QPOs), and compare the model with the updated twin kHz QPO data. For the 17 NS X-ray sources with the simultaneously detected twin kHz QPO frequencies, the stellar mass M and radius R constraints are given by means of the derived parameter A in the model, which is associated with the averaged mass density of star as ${\rm \lan ρ\ran = 3M/(4πR^{3}) \simeq 2.4\times 10^{14} (g/cm^{3}) (A/0.7)^{2}}$, and we also compare the M-R constraints with the star equations of states. Moreover, we also discuss the theoretical maximum kHz QPO frequency and maximum twin peak separation, and some expectations on SAX J1808.4-3658 are mentioned, such as its highest kHz QPO frequency $\sim$~870 (Hz), which is about 1.4-1.5 times less than those of the other known kHz QPO sources. The estimated magnetic fields for both Z sources (about Eddington accretion rate $\med$) and Atoll sources ($ 1% \med$) are approximately $10^9$ G and $10^8$ G respectively.

description: We report a novel high pressure structural sequence for the functionally graded thermoelectric, narrow band gap semiconductor AgSbTe$_{2}$, using angle dispersive x-ray diffraction in a diamond anvil cell with synchrotron radiation at room temperature. The compound undergoes a B1 to B2 transition; the transition proceeds through an intermediate amorphous phase found between 17-26 GPa that is quenchable down to ambient conditions. The pressure induced structural transition observed in this compound is the first of its type reported in this ternary cubic family, and it is new for the B1-B2 transition pathway reported to date. Density Functional Theory (DFT) calculations performed for the B1 and B2 phases are in good agreement with the experimental results.

description: Investigating out-of-equilibrium dynamics with two-dimensional (2D) systems is of widespread theoretical interest, as these systems are strongly influenced by fluctuations and there exists a superfluid phase transition at a finite temperature. In this work, we realise matter-wave interference for degenerate Bose gases, including the first demonstration of coherent splitting of 2D Bose gases using magnetic trapping potentials. We improve the fringe contrast by imaging only a thin slice of the expanded atom clouds, which will be necessary for subsequent studies on the relaxation of the gas following a quantum quench.

If adult education were integrated into university education of BSc or MSc level, extension courses for practicing teachers would not loose their importance, but on the contrary, those would be arranged at an upper level. Adult education should be changed to competence based education, as the competent andragogical knowledge can hide the possibility of some extra profit. Teachers and trainers in vocational education, who are engineers and economists etc. at the same time, would mean potentially the best qualified adult educators, whose teaching competences should only be completed with andragogical competences. They are appropriate and can be let in one the task, but they are not used up.

description: We have obtained Gemini/GMOS spectra for 22 GCs associated with NGC 3379. We derive ages, metallicities and alpha-element abundance ratios from simple stellar population models using the multi-index chi^2 minimisation method of Proctor & Sansom (2002). All of these GCs are found to be consistent with old ages, i.e. >10 Gyr, with a wide range of metallicities. A trend of decreasing alpha-element abundance ratio with increasing metallicity is indicated. The projected velocity dispersion of the GC system is consistent with being constant with radius. Non-parametric, isotropic models require a significant increase in the mass-to-light ratio at large radii. This result is in contrast to that of Romanowsky et al. (2003) who find a decrease in the velocity dispersion profile as determined from planetary nebulae. Our constant dispersion requires a normal sized dark halo, although without anisotropic models we cannot rigorously determine the dark halo mass. A two-sided chi^2 test over all radii, gives a 2 sigma difference between the mass profile derived from our GCs compared to the PN-derived mass model of Romanowsky et al. (2003). However, if we restrict our analysis to radii beyond one effective radius and test if the GC velocity dispersion is consistently higher, we determine a >3 sigma difference between the mass models, and hence favor the conclusion that NGC 3379 does indeed have dark matter at large radii in its halo.

Models of fluidized granular materials: examples of non-equilibrium stationary states

description: We review some models of granular materials fluidized by means of external forces such as: random homogeneous forcing with damping, vibrating plates, flow in an inclined channel and flow in a double well potential. All these systems show the presence of density correlations and non-Gaussian velocity distributions. These models are useful to understand the role of a kinetically defined ``temperature'' (in this case the so-called {\em granular temperature}) in a non-equilibrium stationary state. In the homogeneously randomly driven gas the granular temperature is {\em different} from that of the driving bath. Moreover two different granular materials mixed together may stay in a stationary state with different temperatures. At the same time, granular temperature determines (as in equilibrium systems) the escape time from a well in a double well potential.

description: Intelligent systems designed using machine learning algorithms require a large number of labeled data. Background knowledge provides complementary, real world factual information that can augment the limited labeled data to train a machine learning algorithm. The term Knowledge Graph (KG) is in vogue as for many practical applications, it is convenient and useful to organize this background knowledge in the form of a graph. Recent academic research and implemented industrial intelligent systems have shown promising performance for machine learning algorithms that combine training data with a knowledge graph. In this article, we discuss the use of relevant KGs to enhance input data for two applications that use machine learning -- recommendation and community detection. The KG improves both accuracy and explainability.

description: We demonstrate Resonant Tunneling Diodes, embedded in double metal cavities, strongly coupled to the cavity field, while maintaining their electronic properties. We measure the polariton dispersion and find a relative vacuum Rabi splitting of 16%, which explicitly qualifies for the strong-coupling regime. Additionally we show that electronic transport has a significant influence on the polaritons by modulating the coupling strength. The merge between electronic transport and polaritonic physics in our devices opens up a new aspect of cavity quantum electro-dynamics and integrated photonics.

description: Based on the results from this study our conclusions refer to the following ideas: The economic degree still is the first choice for enrollment in the higher education. Students believe that a diploma achieved in a economic faculty could help them in finding a good job. The competition in labor force market increasing and give advantages to employers in attracting good capacities and knowledge. Students believe that a work experience along the period of higher education process could be a good start for being employed. The most important weaknesses identified by graduates are: tools and methods of teaching process and the content of textbooks or study materials. The students appreciate as important for higher education system the novelty of the knowledge share in the process and the practical characteristics of the its. The graduates are satisfied by the novelty level of the knowledge and information share but the examination model and practical characteristics seems to be inappropriate. In conclusion the Romanian higher education has to apply the reform started in this sector not only with regulation and curricula changes but also with the opportunities offer to the staff in order to become professionals in teaching and forming activities. This could improve the quality of the education process because the general attitude of people is to place in the center of the educational systems, responsible for the good performance of the students, the professor.

description: Films produced by assembling bare gold clusters well beyond the electrical percolation threshold show a resistive switching behavior whose investigation has started only recently. Here we address the challenge to charaterize the resistance of a nanogranular film starting from limited information on the structure at the microscopic scale by the means of Bruggeman's approach to multicomponent media, within the framework of Effective Medium Approximations. The approach is used to build a model that proves that the observed resistive switching can be explained by thermally regulated local structural rearrangements.

description: The contemporary education process is necessary tied to information-technology and to Informatic. By using the Internet as source and as knowledge’s transmission modality one modifies the learning parameters. From the quantitative point of view, the Informatic increases the education process efficiency. From the qualitative point of view, the Informatic imposes a change of the education paradigm. The Informatic determines status modifications for the purveyor and for the beneficiary of the knowledge. The Informatic modifies the psychosocial characteristics of the knowledge process too. Using the Internet supposes the assumption of at least two levels reality. A more than one level reality representation agrees with the quantum mechanics and with relativity theory. Such reality representation is pertinent as contemporary knowledge paradigm.

description: We investigate the dynamical and chemical evolution of the Large Magellanic Cloud (LMC) interacting with the Galaxy and the Small Magellanic Cloud (SMC) based on a series of self-consistent chemodynamical simulations. Our numerical models are aimed at explaining the entire properties of the LMC, i.e., the observed structure and kinematics of its stellar halo and disk components as well as the populations of the field stars and star clusters. The main results of the present simulations are summarized as follows. (1) Tidal interaction between the Clouds and the Galaxy during the last 9 Gyr transforms the initially thin, non-barred LMC disk into the three different components: the central bar, thick disk, and kinematically hot stellar halo. The central bar is composed both of old field stars and newly formed ones with each fraction being equal in its innermost part. The final thick disk has the central velocity dispersion of $\sim$ 30 km s$^{-1}$ and shows rotationally supported kinematics with $V_{\rm m}/σ_{0}$ $\sim$ 2.3. (2) The stellar halo is formed during the interaction, consisting mainly of old stars originating from the outer part of the initially thin LMC disk. The outer halo shows velocity dispersion of $\sim$ 40 km s$^{-1}$ at the distance of 7.5 kpc from the LMC center and has somewhat inhomogeneous distribution of stars. The stellar halo contains relatively young, metal-rich stars with the mass fraction of 2 %.

description: We present a network-based modal analysis technique that identifies key dynamical paths along which perturbations amplify over a time-varying base flow. This analysis is built upon the Katz centrality, which reveals the flow structures that can effectively spread perturbations over a time-evolving network of vortical interactions on the base flow. Motivated by the resolvent form of the Katz function, we take the singular value decomposition of the resulting communicability matrix, complementing the resolvent analysis for fluid flows. The right-singular vectors, referred to as the broadcast modes, give insights into the sensitive regions where introduced perturbations can be effectively spread and amplified over the entire fluid-flow network that evolves in time. We apply this analysis to a two-dimensional decaying isotropic turbulence. The broadcast mode reveals that vortex dipoles are important structures in spreading perturbations. By perturbing the flow with the principal broadcast mode, we demonstrate the utility of the insights gained from the present analysis to effectively modify the evolution of turbulent flows. The current network-inspired work presents a novel use of network analysis to guide flow control efforts, in particular for time-varying base flows.
Assessing the motivations and implications of US biological warfare policy

Publisher: name: University of British Columbia

description: The 1972 Biological and Toxin Weapons Convention (BTWC) was the first international treaty in the history of arms control to successfully ban an entire class of strategic military weapons. Despite its historical precedent however, subsequent grievous violations of the convention by at least two state parties to the treaty revealed its profound weaknesses. In the absence of even the most rudimentary verification mechanisms, the diffusion and advancement of biotechnology resulted in severe violations by both the former Soviet Union and the former government of Iraq. In response to the violations of the international regime banning biological warfare, the state parties to the BTWC began to take steps to repair the regime in the early 1990s by initiating negotiations to create a set of multilateral verification protocols for the convention. In 2001, after have spent seven long years in negotiation, the positions of the state parties to the BTWC had begun to converge on a set of verification instruments that satisfied the vast majority of the participating nations. This progress however, was abruptly undercut by the United States when it not only rejected the draft verification protocols that had been negotiated by the state parties to the convention, but it also went on to reject the very process of strengthening the regime through the creation of multilateral verification mechanisms. To date, the U.S. policy toward the development of verification protocols has effectively prevented the international community from moving forward to strengthen the BTWC, as the U.S. is the world leader in biotechnology and any effective verification protocols would need the support of the United States. While the current U.S. policy toward verification protocols represents a formidable setback in the international community's effort to restore credibility to the BTWC, current illicit research and development by the U.S. military into the creation a new generation of offensive biological weapons has dealt yet another blow to the long standing international norm against biological warfare. In order to restore credibility to the international regime banning biological warfare, the U.S. must not only retreat from its polarized position of opposing the institution of multilateral verification protocols, but it must also bring itself back into full compliance with its obligations under the BTWC.

description: The paper intends to perform a relevant study on the closed-end fund puzzle in the perspective of an emerging market. Quarterly data of 36 closed-end mutual funds traded in Dhaka Stock Exchange are collected over the sample period of 2016 to 2019. Dependent and independent variables are mapped down by exploring previous researches. Weight of top 10 investments, fund size, fund age, fund maturity, turnover and dividend yield are taken as explanatory variable to analyze the impact on CEF discount. A fixed effects panel regression is performed on the data set with few diagnostic tests to ensure the reliability of the analysis conducted. The results show that, the variable fund size and fund maturity have a significant positive and turnover has a significant negative impact on CEF discount while the impact of weight of top 10 investments, dividend yield and fund age are found insignificant.

description: The new approach to measurement of IC of community was presented. In the conceptualization of the problem it was proposed to treat the IC as a latent construct that is measured via directly observable proxies. The results presented are the final obtained after having discarded some variables due to their lack of fit to the estimated models. It is worth mentioning that such a situation concerned only two constructs – the most complex one – activity, and orientation on self-education. The reason in the former case was its complexity and in the latter – the variable the expenses on education despite highly correlated with willingness to update knowledge, professional skills, take part in workshops (P3) was not significant and therefore discarded. Nonetheless CFA performed provided proofs that the conceptualization was quite good as all observable variables loaded strongly to the factors where they were expected to load. All fit indices, despite not always at the maximum level, were acceptable given the small sample size. The most stipulations concerned the activity factor but it was understandable as this construct was the most complex. Finally, it is important to stress that this model is not and cannot be the only one proper and possible. This is the very first one conceptualized for Lubelszczyzna region and in the future it will be re-formulated but do so more research and thus more time and data is needed.

description: We discuss the effect of clustering for the determination of the merger rate of binary black holes in the LIGO mass range. While for a Poissonian initial distribution, and assuming isolated binaries, the allowed fraction of Primordial Black Holes (PBHs) to dark matter (DM) is a few percent, we show that this bound can be relaxed if PBHs are clustered. More precisely we show that for large clustering the merger rate can drop with increasing fraction of PBHs, introducing a degeneracy in the parameters of the theory consistent with a given present merger rate, and allowing all the DM to be in the form of stellar mass PBHs. This degeneracy can however be broken by looking at the evolution of the merger rate with redshift. For a simple clustering model that we consider, we show that the LIGO projected sensitivity can disentangle, through the observation of a stochastic background of gravitational waves, different clustered distributions having the same present merger rate.

description: Using quarterly U.S. census division data for time period 1975-2006, this paper investigates the dynamic relationships among the house prices of nine divisions (regions): Pacific, Mountain, South Atlantic, Middle Atlantic, New England, East South Central, West South Central, West North Central, and East North Central. Johansen’s ML procedure is applied to shed light on the short-run and long-run components on the error correction model. Furthermore, a symmetric error-correction model is estimated followed by the contemporaneous causality structure that is provided by the directed acyclic graphs. The latter is used as an “input” for estimating the impulse response functions along with the forecast error variance decompositions. The results provide evidence of the presence of large number of cointegration relations between the regional house prices in the US. Moreover, in most cases, West North Central and New England appear to strongly and positively lead the house price changes in most other regions. The statement holds for Middle Atlantic which actually generates negative responses. On the other hand, house prices in East North Central and Mountain are highly influenced by changes in house prices of other regions. These results mostly hold for the dynamic period or from time horizon 0 (contemporaneous) to 35 (8.5 years). Furthermore, the real estate market in the US appears to be mainly led by regions that are influential in many other ways, such as financial, economic, etc.

description: Presented here are results of simulations of neutron background performed for a time projection chamber acting as a particle dark matter detector in an underground laboratory. The investigated background includes neutrons from rock and detector components, generated via spontaneous fission and (alpha, n) reactions, as well as those due to cosmic-ray muons. Neutrons were propagated to the sensitive volume of the detector and the nuclear recoil spectra were calculated. Methods of neutron background suppression were also examined and limitations to the sensitivity of a gaseous dark matter detector are discussed. Results indicate that neutrons should not limit sensitivity to WIMP-nucleon interactions down to a level of (1 - 3) x 10^{-8} pb in a 10 kg detector.

description: Any one-field inflation is actually realized in a multifield configuration because the inflaton must have couplings with other fields to reheat the universe and is coupled to all other fields at least gravitationally. In all single inflaton models, it is explicitly or implicitly assumed that the heavier fields are stuck to their potential minima during inflation, which are time-dependent in general. We present a formalism to calculate curvature perturbations in such a time-dependent background and show that the proper expression can be obtained using a single-field analysis with a reduced potential in which all these heavy fields are situated at their respective, time-dependent minima. Our results provide a firm ground on the conventional calculation.

Risk and Uncertainty

description: This research analyzes daily commodity spot prices and designs risk contingent structured financial instruments as a means to mitigate business and financial risk by reducing debt obligations depending on the embedded commodity options whose payoffs are linked with commodity price fluctuations. Models are developed for operating loans and farm mortgages. The results show that the distributions with the embedded option have higher probability of greater returns and the embedded option with the repayment contingent on the price fluctuation reduces the downside risk of the return from the investment.

description: Complex geometries as common in industrial applications consist of multiple patches, if spline based parametrizations are used. The requirements for the generation of analysis-suitable models are increasing dramatically since isogeometric analysis is directly based on the spline parametrization and nowadays used for the calculation of higher-order partial differential equations. The computational, or more general, the engineering analysis necessitates suitable coupling techniques between the different patches. Mortar methods have been successfully applied for coupling of patches and for contact mechanics in recent years to resolve the arising issues within the interface. We present here current achievements in the design of mortar technologies in isogeometric analysis within the Priority Program SPP 1748, Reliable Simulation Techniques in Solid Mechanics.

description: The USDA Farm Service Agency (FSA) direct farm loan program is designed to provide credit to family-sized farms unable to obtain credit from conventional sources at reasonable rates and terms despite having sufficient cash flow to repay and an ability to fully securitize the loan. FSA policy encourages borrowers to exit the program as soon as possible. This study uses Cox proportional hazard models in a competing risks framework to identify predictive factor of: (1) loan success or default, and (2) length of time to loan termination. Survey data from 1925 direct loans originated in federal fiscal years 1994-95 are used for analysis. Only data available to FSA at time of origination were collected. Since these data are all the information FSA has at time of loan origination, the competing risk models provide an alternative method for measuring priori relative riskiness indicated by borrower and loan characteristics. Results indicate that borrower financial strength, intensity of borrowers' current relationship with FSA and loan characteristics are significant measures of loan risk.
Entanglement and the Einstein-Podolsky-Rosen paradox with coupled intracavity optical downconverters

description: We show that two evanescently coupled $χ^{(2)}$ parametric downconverters inside a Fabry-Perot cavity provide a tunable source of quadrature squeezed light, Einstein-Podolsky-Rosen correlations and quantum entanglement. Analysing the operation in the below threshold regime, we show how these properties can be controlled by adjusting the coupling strengths and the cavity detunings. As this can be implemented with integrated optics, it provides a possible route to rugged and stable EPR sources.

Negotiating femininity : an expoloratory study of young women’s everyday experiences
Creators: name: Carter, Claire L.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis explores how young women negotiate femininity in their everyday lives. My research is based upon a theoretical analysis of current literature on femininity, and is informed by a group interview. The main areas of emphasis within the literature focus on the problematic of how women 'do' and explore the potential agency that women enact in the construction of their identities. My analysis of these ideas gave rise to three themes that depict the different, but often overlapping, theoretical positions on femininity. Firstly, that women are disciplined to be feminine, secondly, that women enact agency in the development of their identities, and thirdly, women negotiate their ever-changing identities in relation to social as well as individual pressures and circumstances. Through exploring and critiquing these themes I suggest that negotiation, as an approach, enables femininity to be theorized as a cultural discourse that shapes and disciplines women, as well as a conscious, negotiated embodiment. Furthermore, the findings from the group interview demonstrate the importance of bringing women's lived experience into the centre of analyses of identity and agency, by providing insight into how femininity is negotiated.

Polaron action for multimode dispersive phonon systems

description: Path-integral approach to the tight-binding polaron is extended to multiple optical phonon modes of arbitrary dispersion and polarization. The non-linear lattice effects are neglected. Only one electron band is considered. The electron-phonon interaction is of the density-displacement type, but can be of arbitrary spatial range and shape. Feynman's analytical integration of ion trajectories is performed by transforming the electron-ion forces to the basis in which the phonon dynamical matrix is diagonal. The resulting polaron action is derived for the periodic and shifted boundary conditions in imaginary time. The former can be used for calculating polaron thermodynamics while the latter for the polaron mass and spectrum. The developed formalism is the analytical basis for numerical analysis of such models by path-integral Monte Carlo methods.

description: Nulling interferometry is one of the most promising technologies for imaging exoplanets within stellar habitable zones. The use of photonics for carrying out nulling interferometry enables the contrast and separation required for exoplanet detection. So far, two key issues limiting current-generation photonic nullers have been identified: phase variations and chromaticity within the beam combiner. The use of tricouplers addresses both limitations, delivering a broadband, achromatic null together with phase measurements for fringe tracking. Here, we present a derivation of the transfer matrix of the tricoupler, including its chromatic behaviour, and our 3D design of a fully symmetric tricoupler, built upon a previous design proposed for the GLINT instrument. It enables a broadband null with symmetric, baseline-phase-dependent splitting into a pair of bright channels when inputs are in anti-phase. Within some design trade space, either the science signal or the fringe tracking ability can be prioritised. We also present a tapered-waveguide $180^\circ$-phase shifter with a phase variation of $0.6^\circ$ in the $1.4-1.7~μ$m band, producing a near-achromatic differential phase between beams{ for optimal operation of the tricoupler nulling stage}. Both devices can be integrated to deliver a deep, broadband null together with a real-time fringe phase metrology signal.

description: Weak gravitational lensing of background galaxies provides a direct probe of the projected matter distribution in and around galaxy clusters. Here we present a self-contained pedagogical review of cluster--galaxy weak lensing, covering a range of topics relevant to its cosmological and astrophysical applications. We begin by reviewing the theoretical foundations of gravitational lensing from first principles, with special attention to the basics and advanced techniques of weak gravitational lensing. We summarize and discuss key findings from recent cluster--galaxy weak-lensing studies on both observational and theoretical grounds, with a focus on cluster mass profiles, the concentration--mass relation, the splashback radius, and implications from extensive mass calibration efforts for cluster cosmology.
