description: Background: In aerodynamic levitation, solids and liquids are floated in a vertical gas stream. In combination with CO2-laser heating, containerless melting at high temperature of oxides and silicates is possible. We apply aerodynamic levitation to bulk rocks in preparation for microchemical analyses, and for evaporation and reduction experiments. Results: Liquid silicate droplets (~2 mm) were maintained stable in levitation using a nozzle with a 0.8 mm bore and an opening angle of 60°. The gas flow was ~250 ml min-1. Rock powders were melted and homogenized for microchemcial analyses. Laser melting produced chemically homogeneous glass spheres. Only highly (e.g. H2O) and moderately volatile components (Na, K) were partially lost. The composition of evaporated materials was determined by directly combining levitation and inductively coupled plasma mass spectrometry. It is shown that the evaporated material is composed of Na > K >> Si. Levitation of metal oxide-rich material in a mixture of H2 and Ar resulted in the exsolution of liquid metal. Conclusions: Levitation melting is a rapid technique or for the preparation of bulk rock powders for major, minor and trace element analysis. With exception of moderately volatile elements Na and K, bulk rock analyses can be performed with an uncertainty of ± 5% relative. The technique has great potential for the quantitative determination of evaporated materials from silicate melts. Reduction of oxides to metal is a means for the extraction and analysis of siderophile elements from silicates and can be used to better understand the origin of chondritic metal.

Powering the city : planning for the future

description: This study addresses a topic that receives very little attention in traditional planning circles: the reliability of the electrical supply in the Lower Mainland of British Columbia, Canada. The economic and social viability of this region is highly dependent on electrical power and while the electricity needed to supply its critical infrastructure is currently available and relatively inexpensive, research indicates that this may not be the case in the near future. The purpose of this thesis is twofold: first to make the case that the Lower Mainland would benefit from greater redundancy in electrical energy supply and, second, to investigate supply-side options available to create a forward looking, sustainable and secure electrical supply. To understand what some of the challenges to displacing conventional sources of electricity are, academics, members of industry, communitybased organizations and government as well as senior employees of conventional energy providers were interviewed. Twenty-eight local experts were asked to identify both what they perceived as the principle challenges or barriers to the implementation of small-scale renewable energy, and what opportunities exist in this field. The most commonly identified challenges include: i) the relatively high price of alternative technologies, ii) the attitudes and practices of local developers and the current building environment, iii) lack of awareness of energy-related issues and alternatives, iv) the relatively low price of electricity and natural gas, v) status quo municipal land use planning, and vi) uninformed municipal officials. Areas which were identified as important to promote the proliferation of small-scale, renewable generation include: i) the provision of alternative financing mechanisms to overcome high first-costs, ii) new ways to use existing municipal tools, iii) the development of large scale demonstration projects, iv) improved marketing, and v) the enhancement of general and specifically targeted educational and training opportunities. A brief comment regarding possible implementation strategies is also presented.

description: The SARS-CoV-2 virus is primarily transmitted through virus-laden fluid particles ejected from the mouth of infected people. Face covers can mitigate the risk of virus transmission but their outward effectiveness is not fully ascertained. Objective: by using a background oriented schlieren technique, we aim to investigate the air flow ejected by a person while quietly and heavily breathing, while coughing, and with different face covers. Results: we found that all face covers without an outlet valve reduce the front flow through by at least 63% and perhaps as high as 86% if the unfiltered cough jet distance was resolved to the anticipated maximum distance of 2-3 m. However, surgical and handmade masks, and face shields, generate significant leakage jets that may present major hazards. Conclusions: the effectiveness of the masks should mostly be considered based on the generation of secondary jets rather than on the ability to mitigate the front throughflow.

description: We continue the investigation of the spectral theory and exponential asymptotics of Markov processes, following Kontoyiannis and Meyn (2003). We introduce a new family of nonlinear Lyapunov drift criteria, characterizing distinct subclasses of geometrically ergodic Markov processes in terms of inequalities for the nonlinear generator. We concentrate on the class of "multiplicatively regular" Markov processes, characterized via conditions similar to (but weaker than) those of Donsker-Varadhan. For any such process {Phi(t)} with transition kernel P on a general state space, the following are obtained. 1. SPECTRAL THEORY: For a large class of functionals F, the kernel Phat(x,dy) = e^{F(x)}P(x,dy) has a discrete spectrum in an appropriately defined Banach space. There exists a "maximal" solution to the "multiplicative Poisson equation," defined as the eigenvalue problem for Phat. Regularity properties are established for Λ(F) = \log(λ), where λis the maximal eigenvalue, and for its convex dual. 2. MULTIPLICATIVE MEAN ERGODIC THEOREM: The normalized mean E_x[\exp(S_t)] of the exponential of the partial sums {S_t} of the process with respect to any one of the above functionals F, converges to the maximal eigenfunction. 3. MULTIPLICATIVE REGULARITY: The drift criterion under which our results are derived is equivalent to the existence of regeneration times with finite exponential moments for {S_t}. 4. LARGE DEVIATIONS: The sequence of empirical measures of {Phi(t)} satisfies an LDP in a topology finer than the τ-topology. The rate function is Λ^* and it coincides with the Donsker-Varadhan rate function. 5. EXACTR LARGE DEVIATIONS: The partial sums {S_t} satisfy an exact LD expansion, analogous to that obtained for independent random variables.

Tunable deconfined quantum criticality and interplay of different valence-bond solid phases

description: We use quantum Monte Carlo simulations to study a quantum $S=1/2$ spin model with competing multi-spin interactions. We find a quantum phase transition between a columnar valence-bond solid (cVBS) and a Néel antiferromagnet (AFM), as in the scenario of deconfined quantum-critical points, as well as a transition between the AFM and a staggered valence-bond solid (sVBS). By continuously varying a parameter, the sVBS--AFM and AFM--cVBS boundaries merge into a direct sVBS--cVBS transition. Unlike previous models with putative deconfined AFM--cVBS transitions, e.g., the standard $J$-$Q$ model, in our extended $J$-$Q$ model with competing cVBS and sVBS inducing terms the transition can be tuned from continuous to first-order. We find the expected emergent U(1) symmetry of the microscopically $Z_4$ symmetric cVBS order parameter when the transition is continuous. In contrast, when the transition changes to first-order the clock-like $Z_4$ fluctuations are absent and there is no emergent higher symmetry. We argue that the confined spinons in the sVBS phase are fracton-like. We also present results for an SU(3) symmetric model with a similar phase diagram. The new family of models can serve as a useful tool for further investigating open questions related to deconfined quantum criticality and its associated emergent symmetries.

The branching ratios calculated in our approach for $B^0 \to \bar D^{(*)0} η$ agree with current experiments. By neglecting the gluonic contribution, we predict the branching ratios of $B^0 \to \bar D^{(*)0} η'$ are at the comparable size of $B^0 \to \bar D^{(*)0} π^0$, but smaller than that of $B^0 \to \bar D^{(*)0} η$.

Two types (Y and U type) of the waveguide bends utilizing the circular photonic crystal are studied. It has been shown, compared with the conventional photonic crystal waveguide bends, transmission properties for these bends can be significantly improved. Over a 6.4% bandwidth, less than 1-dB loss/bend are observed. U bent waveguide, i.e., $180^o$ bend, can be easily realized with low loss using the circular photonic crystal.

Year: 2010

description: The interpretation of processes yielding aqueous contaminant removal in the presence of elemental iron (e.g. in Fe(0)/H(2)O systems) is subject to numerous complications. Reductive transformations by Fe(0) and its primary corrosion products (Fe(II) and H/H(2)) as well as adsorption onto and co-precipitation with secondary and tertiary iron corrosion products (iron hydroxides, oxyhydroxides, and mixed valence Fe(II)/Fe(III) green rusts) are considered the main removal mechanisms on a case-to-case basis. Recent progress involving adsorption and co-precipitation as fundamental contaminant removal mechanisms have faced a certain scepticism. This work shows that results from electrocoagulation (EC), using iron as sacrificial electrode, support the adsorption/co-precipitation concept. It is reiterated that despite a century of commercial use of EC, the scientific understanding of the complex chemical and physical processes involved is still incomplete.

description: Quantum sensing explores protocols using the quantum resource of sensors to achieve highly sensitive measurement of physical quantities. The conventional schemes generally use unitary dynamics to encode quantities into sensor states. In order to measure the spectral density of a quantum reservoir, which plays a vital role in controlling the reservoir-caused decoherence to microscopic systems, we propose a nonunitary-encoding optical sensing scheme. Although the nonunitary dynamics for encoding in turn degrades the quantum resource, we surprisingly find a mechanism to make the encoding time a resource to improve the precision and to make the squeezing of the sensor a resource to surpass the shot-noise limit. Our result shows that it is due to the formation of a sensor-reservoir bound state. Enriching the family of quantum sensing, our scheme gives an efficient way to measure the quantum reservoir and might supply an insightful support to decoherence control.
A Dynamic Model of Social Network Formation

Subjects: subject: Probability (math.PR)

description: We consider a dynamic social network model in which agents play repeated games in pairings determined by a stochastically evolving social network. Individual agents begin to interact at random, with the interactions modeled as games. The game payoffs determine which interactions are reinforced, and the network structure emerges as a consequence of the dynamics of the agents' learning behavior. We study this in a variety of game-theoretic conditions and show that the behavior is complex and sometimes dissimilar to behavior in the absence of structural dynamics. We argue that modeling network structure as dynamic increases realism without rendering the problem of analysis intractable.

description: We study the site-diluted double exchange (DE) model and its effective Ruderman-Kittel-Kasuya-Yosida-like interactions, where localized spins are randomly distributed, with the use of the Self-learning Monte Carlo (SLMC) method. The SLMC method is an accelerating technique for Markov chain Monte Carlo simulation using trainable effective models. We apply the SLMC method to the site-diluted DE model to explore the utility of the SLMC method for random systems. We check the acceptance ratios and investigate the properties of the effective models in the strong coupling regime. The effective two-body spin-spin interaction in the site-diluted DE model can describe the original DE model with a high acceptance ratio, which depends on temperatures and spin concentration. These results support a possibility that the SLMC method could obtain independent configurations in systems with a critical slowing down near a critical temperature or in random systems where a freezing problem occurs in lower temperatures.

description: One of the most important tasks of the National Agricultural Research and Innovation Centre Institute of Agricultural Engineering (NARIC MGI) is to annually provide information on the evolution of agricultural machine operation costs in Hungary. Therefore, the Institute – in addition to other activities – monitors and updates changes concerning agricultural machinery through the use of operational data and values of basic farms on a yearly basis. The work results in the development and publication of a booklet which best summarizes the actual cost of agricultural work performed by different machines. It contains the average performance and cost of agricultural machines and equipment calculated by expected prices, wages, and other costs. In this article, our aim is to present the main results of the observation and summarize the main conclusions of traditional and organic farms in Hungary.

description: A theory for diffusivity estimation for spatially extended activator-inhibitor dynamics modelling the evolution of intracellular signaling networks is developed in the mathematical framework of stochastic reaction-diffusion systems. In order to account for model uncertainties, we extend the results for parameter estimation for semilinear stochastic partial differential equations, as developed in [PS20], to the problem of joint estimation of diffusivity and parametrized reaction terms. Our theoretical findings are applied to the estimation of effective diffusivity of signaling components contributing to intracellular dynamics of the actin cytoskeleton in the model organism Dictyostelium discoideum.

description: Automatic Defect Analysis and Qualification (ADAQ) is a collection of automatic workflows developed for high-throughput simulations of magneto-optical properties of point defect in semiconductors. These workflows handle the vast number of defects by automating the processes to relax the unit cell of the host material, construct supercells, create point defect clusters, and execute calculations in both the electronic ground and excited states. The main outputs are the magneto-optical properties which include zero-phonon lines, zero-field splitting, and hyperfine coupling parameters. In addition, the formation energies are calculated. We demonstrate the capability of ADAQ by performing a complete characterization of the silicon vacancy in silicon carbide in the polytype 4H (4H-SiC).

description: The aim of the study was to examine the changes in acreage of fruit trees and shrubs in Poland and to verify that changes the size of the absolute crops acreage also were accompanied by changes in the participation in the structure of crops. The basis for analysis were statistical data of GUS on the area of cultivation of fruit trees and shrubs. The scope of the analysis includes two periods, beginning in the census years: 2002-2009 and 2010-2015. The changes were specified using the index and the coefficient of linear regression. There were also specified the significance of the differences between the average area of crops in the two periods. The analysis shows that the contribution of each species in the structure of fruit crops in Poland has not changed substantially over the analysis period. There are trends in reducing growing area of plum trees, sour cherries and gooseberries and the increase in acreage of blueberries, raspberries and hazelnuts, however, the share of these species and the changes are not enough to result in changes to the structure of the acreage of fruit crops in Poland.
Expression of human ABCG1 in mice modulates cholesterol metabolite levels and does not influence guanidine-extractable abeta levels in brain
Creators: name: Burgess, Braydon
Publisher: name: University of British Columbia
Year: 2011

description: Growing evidence suggests that cholesterol plays a key role in Alzheimer's Disease (AD). Importantly, membrane cholesterol levels influence generation of the amyloid-beta (Aß) peptide from amyloid precursor protein (APP). The amyloid cascade hypothesis of AD posits that increased accumulation of (Aß) peptides and their deposition as amyloid in the brain, promote neurodegeneration in AD. The ATP-binding-cassette-G1 (ABCG1) transporter is highly expressed in the brain and periphery and is believed to regulate cholesterol levels in peripheral cells and tissues. This suggests that the ABCG1-mediated effects on cholesterol homeostasis may influence Aß production and AD. To determine the effect of ABCG1 overexpression in brain and to evaluate whether ABCG1 could influence Aß production or amyloid deposition, ABCG1 overexpression was studied both in vitro and using a novel ABCG1 transgenic mouse. We generated an ABCG1 overexpressing mouse containing the entire ABCG1 genomic locus and regulatory sequence, to promote "physiological" expression patterns of overexpression. We found that the ABCG1 transgene is physiologically regulated in vivo and overexpressed 3-6-fold at the protein level. Using a LacZ reporter driven by endogenous ABCG1 regulatory sequences, we showed that ABCG1 is highly expressed in hippocampal neurons. Importantly, ABCG1 overexpressing mice express the ABCG1 transgene in primary neurons and astrocytes. Unexpectedly, the level of cholesterol biosynthetic precursors and 24S-hydroxycholesterol levels were reduced in adult ABCG1 overexpressing brain, suggesting a novel function of ABCG1. Total levels of cholesterol and other lipids were unaffected. In contrast to numerous published studies that studied constitutive overexpression of ABCG1 in vitro, overexpression of physiologically regulated ABCG1 in primary astrocytes did not facilitate cholesterol efflux to HDL. These experiments suggest that the role of ABCG1 in vivo is not entirely understood and that ABCG1 may influence cholesterol biosynthesis or cholesterol precursor transport. ABCG1 overexpression increased APP processing by ß-secretase and the production of Aß in transfected HEK cells. However, in vivo ABCG1 overexpression or deficiency did not significantly affect murine Aß levels nor did overexpression affect amyloid formation or ß-secretase mediated APP cleavage. These experiments suggest that ABCG1 overexpression does not impact amyloid formation as hypothesized.

description: We evaluate bulk distribution of energies, pressures and various D-brane/F-string charges generated by nontrivial matrix configurations in nonabelian D-brane effective field theories, using supergravity source density formulas derived originally in Matrix theory. Off-diagonal elements of worldvolume nonabelian fields, especially transverse scalar fields, induce various interesting bulk structures exhibiting the shape of branes. First, we study the energy distribution of string-brane networks generated in the bulk by the Yang-Mills monopoles and the 1/4 BPS dyons, and confirm force balance of them. An application to the Yang-Mills description of recombination of intersecting D-branes gives results indicating presence of the tachyon matter. Second, we analyse the shape of fuzzy D-branes given by nonabelian scalar fields which are mutually noncommutative. We employ fuzzy S^2, fuzzy S^4 and fuzzy cylinder/supertube as matrix configurations of N D0-branes representing higher dimensional noncommutative D-branes. We find that in the continuum (large N) limit the D-brane charge distributions become in the expected shape of a sphere or a cylinder with an infinitesimal thickness. However, the distributions found for finite N are difficult to interpret, which leaves a puzzle for a possible dual description in terms of higher dimensional D-branes. A resolution is provided with use of an ordering ambiguity in the charge density formulas.

On the limits of photon-mediated interactions in one-dimensional photonic baths

description: The exchange of off-resonant propagating photons between distant quantum emitters induces coherent interactions among them. The range of such interactions, and whether they are accompanied by dissipation, depends on the photonic energy dispersion, its dimensionality, and/or the light-matter couplings. In this manuscript, we characterize the limits of photon-mediated interactions for the case of generic one-dimensional photonic baths under the typical assumptions, that are, having finite range hoppings for the photonic bath plus local and rotating-wave light-matter couplings. In that case, we show how, irrespective of the system's parameter, the coherent photon-mediated interactions can always be written as a finite sum of exponentials, and thus can not display a power-law asymptotic scaling. As an outlook, we show how by relaxing some of these conditions, e.g., going beyond local light-matter couplings (e.g., giant atoms) or with longer-range photon hopping models, power-law interactions can be obtained within certain distance windows, or even in the asymptotic regime for the latter case.

description: The global grape and wine market has been rearranged during the past 15 years. Over the course of events, as new world wines gained ground, further emerging countries joined in and the production of old world wines decreased, giving rise to a new era. It was affected by globalization that placed concentrated markets in an advantageous position. As a result, there is a growing emphasis on the formation of vine growth and wine production collaboration networks in case of both the new world and European countries, which are able to provide solutions to global challenges arising as a result of global wine market development. In European wine producing countries with great traditions, integration, necessary for the stable operation of the sector, was established much earlier, typically in the form of producer cooperatives. In new areas, concentration began later, thus forming clusters constituting an appropriate form in many cases. This paper examines the necessity of cooperation and overviews the advantages and drawbacks that can be obtained from it. It compares wine producing collaboration networks in European countries and areas overseas. The aim of the study is to find the most important attributes leading to success
Characterizing the discoloration of methylene blue in Fe0/H2O systems.

Publisher: name: FID GEO

description: Methylene blue (MB) was used as a model molecule to characterize the aqueous reactivity of metallic iron in Fe(0)/H(2)O systems. Likely discoloration mechanisms under used experimental conditions are: (i) adsorption onto Fe(0) and Fe(0) corrosion products (CP), (ii) co-precipitation with in situ generated iron CP, (iii) reduction to colorless leukomethylene blue (LMB). MB mineralization (oxidation to CO(2)) is not expected. The kinetics of MB discoloration by Fe(0), Fe(2)O(3), Fe(3)O(4), MnO(2), and granular activated carbon were investigated in assay tubes under mechanically non-disturbed conditions. The evolution of MB discoloration was monitored spectrophotometrically. The effect of availability of CP, Fe(0) source, shaking rate, initial pH value, and chemical properties of the solution were studied. The results present evidence supporting co-precipitation of MB with in situ generated iron CP as main discoloration mechanism. Under high shaking intensities (>150 min(-1)), increased CP generation yields a brownish solution which disturbed MB determination, showing that a too high shear stress induced the suspension of in situ generated corrosion products. The present study clearly demonstrates that comparing results from various sources is difficult even when the results are achieved under seemingly similar conditions. The appeal for an unified experimental procedure for the investigation of processes in Fe(0)/H(2)O systems is reiterated.
Elemental metals for environmental remediation: learning from cementation process.
Creators: name: Noubactep, C.
Publisher: name: FID GEO

description: The further development of Fe(0)-based remediation technology depends on the profound understanding of the mechanisms involved in the process of aqueous contaminant removal. The view that adsorption and co-precipitation are the fundamental contaminant removal mechanisms is currently facing a harsh scepticism. Results from electrochemical cementation are used to bring new insights in the process of contaminant removal in Fe(0)/H(2)O systems. The common feature of hydrometallurgical cementation and metal-based remediation is the heterogeneous nature of the processes which inevitably occurs in the presence of a surface scale. The major difference between both processes is that the surface of remediation metals is covered by layers of own oxide(s) while the surface of the reducing metal in covered by porous layers of the cemented metal. The porous cemented metal is necessarily electronic conductive and favours further dissolution of the reducing metal. For the remediation metal, neither a porous layer nor a conductive layer could be warrant. Therefore, the continuation of the remediation process depends on the long-term porosity of oxide scales on the metal surfaces. These considerations rationalized the superiority of Fe(0) as remediation agent compared to thermodynamically more favourable Al(0) and Zn(0). The validity of the adsorption/co-precipitation concept is corroborated.

description: The study examines preferences of customers of the Spółdzielnia Piekarsko-Ciastkarska bakery in Warsaw regarding attributes of baked goods and rolls produced using the innovative technology “cool rising”, which is a method of regulated dough preparation used in baking “crispy baked goods”. The study applies own survey data collected in November 2014. The majority of respondents were women, most of respondents had at least high school education, and income between 1501PLN and 3000PLN. Summary of responses shows that the most important attributes of baked goods produced using the innovative technology include the longest period of maintaining freshness, delicate and crunchy surface, and well defined taste and aroma. It has to be stressed that bakery customers did not name price an attribute deciding about the purchase what seems to contradict the opinion coinciding with the Law of Demand expressed by the sector’s leaders, namely that the price increase is the primary reason for the baked goods consumption decline. Results of this study indicate sensory attributes of rolls as the most important in encouraging purchase. The application of an innovative technology seems justified in order to stop the systematically declining consumption of bakery products.

description: We investigate the effect of sterile neutrinos that are nearly degenerate with active ones on the flux of ultrahigh-energy cosmic ray neutrinos at earth. This offers a way to probe neutrino oscillations in the mass-squared range (10^{-16} eV^2 < δm^2 < 10^{-11} eV^2) which maybe hard to detect by any other means. Taking into account the present experimental uncertainties of the active-active mixing angles and by allowing any values for the active-sterile mixing angles we find that the ratio of the electron and muon neutrino fluxes may change by -40 % to 70 % in comparison with the ratio in the absence of active-sterile mixing.
