description: In a 2006 article Schlichting conjectured that the negative {\it K--}theory of any abelian category must vanish. This conjecture was generalized in a 2019 article by Antieau, Gepner and Heller, who hypothesized that the negative {\it K--}theory of any category with a bounded {\it t--}structure must vanish. Both conjectures will be shown to be false.

description: Umweltveränderungen beeinflussen nicht nur ganze Zivilisationen, sondern vor allem die Menschen, die sie unmittelbar erleben. Sei es klirrende Kälte, die Menschen erfrieren lässt, Fluten, die Häuser zerstören, oder Dürren, die zu Hungersnöten führen, die Bedrohung von Leib und Leben kann sehr beängstigend sein. Im aktuellen Kapitel betrachte ich deshalb die Geschichte der „Eco-Anxiety“ anhand der klimatischen Veränderungen der letzten 2500 Jahre und deren Auswirkungen auf die Menschheit, konkreter die Ängste, die direkt oder indirekt mit dem Klima zu tun haben. An dieser Stelle ist es mir wichtig anzumerken, dass gesellschaftliche und politische Veränderungen, insbesondere in dem hier dargestellten Ausmaß, stets von vielen Faktoren abhängen und nicht nur auf klimatische Einflüsse allein zurückzuführen sind.

Global maps of the growth of Japanese marine fisheries and fish consumption
Creators: name: Swartz, Wilfram Ken
Publisher: name: University of British Columbia
Year: 2009

description: Globally, consumers are increasingly relying on goods and services produced in other countries. This is particularly true for fish products, nearly 40% of world fish production is currently traded globally. Thus, there now exists a clear disconnect between resource harvesters and resource consumers. This research is concerned with an assessment of fisheries exploitation patterns based on consumption as a complement to assessment based on fisheries catch. Such research requires an examination of two primary modes of fish acquisition: the operation of a country's domestic fishing fleets, i.e., its landings and the purchase of fish caught by foreign fleets, i.e., its fish import. Japanese fish consumption will be used as a case study. Japan has traditionally been one of the world's largest consumers of fish products, with considerable dependence on foreign fisheries resources, initially through the operation of its distant water fleets, and later through the purchase of foreign catches as import. Global maps of Japanese trade statistics were constructed in terms of where catch were likely to have been taken, through a comparison with existing world, landings maps. By combining Japan's trade maps with Japan's catch maps, one can then assess the spatial and temporal patterns of Japanese fish consumption. Examination of the consumption maps indicate that despite the reduction of its distant water fleets, Japan maintains high level consumption throughout the world oceans via its increased reliance on the import of foreign catches. Moreover, maps of Japan's consumption relative to the world catch reveal that Japan remains the most prominent consumer of fisheries resources from many regions of the world, particularly in the South Pacific and the waters around Antarctica. Such maps provide an alternative measure of the level of fisheries exploitation exerted by the demand of fish importing countries. Although the responsibility for ensuring the sustainability of the resource use is on the resource-extracting nation, an understanding of the exploitation pressure exerted by the demand of the importing countries is evidently in their best interest, as it dictates the long-term security and stability of the supply. The mapping of consumption undertaken in my research may lead to more thorough analyses of this issue.

description: An accuracy of the last version of International Reference Ionosphere IRI-2001 at low latitudes is tested by a detailed comparison of longitudinal variations in the equatorial anomaly development following from this model with the ones given by independent ISS-b satellite data. The critical frequency of F2-layer was calculated by either CCIR or URSI submodel, both of which are incorporated into IRI-2001. The main conclusion of our analysis is that the longitudinal variations given by CCIR are substantially oversmoothed in comparison with the ISS-b satellite data, and the variations given by URSI are further smoothed with respect to the CCIR ones. Therefore, further improvements of model description of the low-latitude F2-layer are desirable.

description: The cotton sector has been amongst the most regulated in Africa, and still is to a large extent in West and Central Africa (WCA), despite repeated reform recommendations by international donors. On the other hand, orthodox reforms in East and Southern Africa (ESA) have not always yielded the expected results. This paper uses a stylized contracting model to investigate the link between market structure and equity and efficiency in sub-Saharan cotton sectors and analyze the potential consequences of orthodox reforms in WCA. We argue that the level of the world price and of government intervention, the degree of post-reform competition, as well as the degree of parastatal inefficiency, all contribute to making reforms less attractive (but not less pressing) to farmers and governments in WCA today, as compared to ESA in the 1990s. We illustrate our arguments with empirical observations on the performance of cotton sectors across sub-Saharan Africa.

description: The paper addressees the issues of integration and globalization in the Czech agro-food chain. It describes the situation before 1989 when partial processes of integration took place under strong influence of the state. The relatively closed communist system disabled the globalization as understood by Western sociologists. The paper also examines how the different types of agrofood chain formed under the communist state encounter the integration and globalization known in a market economy after 1989. The character of this connection, and latent conflicts concerning the struggle to influence and to control agro-food chain are documented. Newly emerging types of relations between farmers and food processors with indications as to some factors influencing the action of both groups (especially the role of cultural and social capital), are discussed. The conclusions consider the role of the state, the market and the civil sector (where an important role is played by the grass-root cooperatives) in balancing the relations between local and global levels.

description: The Askey-Wilson algebra is realized in terms of the elements of the quantum algebras $U_q(\mathfrak{su}(2))$ or $U_q(\mathfrak{su}(1,1))$. A new realization of the Racah algebra in terms of the Lie algebras $\mathfrak{su}(2)$ or $\mathfrak{su}(1,1)$ is given also. Details for different specializations are provided. The advantage of these new realizations is that one generator of the Askey-Wilson (or Racah) algebra becomes diagonal in the usual representation of the quantum algebras whereas the second one is tridiagonal. This allows to recover easily the recurrence relations of the associated orthogonal polynomials of the Askey scheme. These realizations involve rational functions of the Cartan generator of the quantum algebras, they are linear with respect to the other generators and depend on the Casimir element of the quantum algebras.

description: This paper describes the crisis faced by the cooperatives in Bulgaria during the period of transition beginning in 1990 when the collapse of the socialist agricultural system started. It examines the transformation of the agrarian relations based on a case study of four villages located in the northeastern part of Bulgaria (the region of Dobrudzha). It points to the declining significance of the cooperatives in the new environment and analyzes the basic reasons for their crisis. The conclusion is that the cooperatives have failed to adapt successfully to the changed economic and political situation in the 1990s rather insisting on continuing with the old socialist mechanisms of collective production lacking new high tech investments and young people with initiative. The philosophy of the transition emphasizing the individual rather than the collective has contributed to the political isolation of the cooperatives and, as a consequence, to their lack of investments and credit.

description: Enduring low agricultural productivity is one of the major causes of rural poverty in South Asia. Based on a review of recent empirical studies, this paper focuses on three key questions: (1) why is agricultural productivity low in the region?; (2) what are the key constraints and opportunities for enhancing agricultural productivity; and (3) what are the effective mechanisms to improve access to key productivity enhancing technologies, factors and services. Two major points raised in the paper are: (a) improved management of land and water is important for increasing productivity, but equally important is farmers' access to non land and water-related inputs and services, which through their complementary relationships with water, increase the productivity and value of water. Even if most of the constraints related to land and water are removed through improved management, the resulting gains in productivity may not be sufficient-in the presence of constraints related to other factors and services-to have any significant impacts on poverty. Therefore, in order to generate any major increases in productivity, farmers' improved access to non land and water-related factors and services is also important; (b) access to these factors and services can be improved by providing them in an integrated manner with public-private sector partnerships. Based on examples of various models, initiatives and practices from Pakistan, India, Sri Lanka, China, Sub-Saharan Mrica and other countries, the study suggests a framework for integrated services provision in the agriculture sector, and raises key research issues and questions to be explored.

Thermal loading on crystals in an X-ray free-electron laser oscillator

Year: 2020

description: X-ray free electron laser oscillators (XFELO) is future light source to produce fully coherent hard X-ray pulses. The X-rays circulate in an optical cavity built from multiple Bragg reflecting mirrors, which has a high reflectance in a bandwidth of ten meV level. The X-ray crystal mirrors exposed to intense X-ray beams in the cavity are subjects to thermal deformations that shift and distort the Bragg reflection. Therefore, the stability of the XFELO operation relies on the abilities of mirrors to preserve the Bragg reflection under such heat load. A new approach was used to analyze the heat load of mirrors and the XFELO operation. The essential light-matter interaction is simulated by the GEANT4 with a dedicated Bragg-reflection physical process to obtain the precise absorption information of the XFELO pulse in the crystals. The transient thermal conduction is analyzed by the finite-element analysis software upon the energy absorption information extract from GEANT4 simulation. A simplified heat-load model is then developed to integrate the heat load in the XFELO. With the help of the heat-load model, the analysis of XFELO operating with several cryogenically cooled diamond mirrors is conducted. The results indicate that the heat load would induce an oscillation when XFELO operates without enough cooling.

description: We have investigated the magnetic field and temperature dependence of the tunneling spectra of the eutectic system Sr2RuO4-Ru. Electric contacts to individual Ru lamellae embedded in Sr2RuO4 enable the tunneling spectra at the interface between ruthenate and a Ru microinclusion to be measured. A zero bias conductance peak (ZBCP) was observed in the bias voltage dependence of the differential conductance, suggesting that Andreev bound states are present at the interface. The ZBCP starts to appear at a temperature well below the superconducting transition temperature. The onset magnetic field of the ZBCP is also considerably smaller than the upper critical field when the magnetic field is parallel to the ab-plane. We propose that the difference between the onset of the ZBCP and the onset of superconductivity can be understood in terms of the existence of the single-component state predicted by Sigrist and Monien.

This paper analyzes the impact of institutional interventions on efficient water management, especially during the land preparation period. It provides a comprehensive understanding of the factors behind prolonged periods of land preparation so that system managers and farmers communities can develop appropriate interventions to reduce water consumption.
A Robust Algorithm for the Pointing Refinement and Registration of Astronomical Images
Creators: name: Masci, Frank J.
name: Makovoz, David
name: Moshir, Mehrdad
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present a generic algorithm for performing astronomical image registration and pointing refinement. The method is based on matching the positions and fluxes of available point sources in image overlap regions. This information is used to compute a set of image offset corrections by globally minimizing a weighted sum of all matched point-source positional differences in a pre-specified reference image frame. A fast linear sparse matrix solver is used for the minimization. From these corrections, the pointings and orientations of images can be refined in either a relative sense where pointings become fixed (registered) relative to a single input image, or, in an absolute sense (in the ICRS) if absolute point source information is known. The latter provides absolute pointing refinement to an accuracy depending on the robustness of point source extractions, match statistics, and accuracy of the astrometric catalog used. The software is currently used in the Spitzer image processing pipelines, although it is adaptable to any astronomical imaging system which uses the FITS image format and WCS pointing standard. We test the algorithm using Monte Carlo simulations and compare them to image data acquired with the Infrared Array Camera (IRAC) on board the Spitzer Space Telescope.

description: We propose a fast impurity solver for the general quantum impurity model based on the perturbation theory around the atomic limit, which can be used in combination with the local density approximation (LDA) and the dynamical mean field theory (DMFT). We benchmark the solver in the two band Hubbard model within DMFT against quantum Monte Carlo (QMC) and numerical renormalization group (NRG) results. We find that the solver works very well in the paramagnetic Mott insulator phase. We also apply this impurity solver to the DMFT study of the anti-ferromagnetic phase transition in the unfrustrated Bethe lattice. The Neel temperature obtained by the fast impurity solver agrees very well with the QMC results in the large Hubbard U limit. The method is a promising tool to be used in combination with the LDA+DMFT to study Mott insulators starting from first principles.

description: We analyze heavy quark free energies in 2-flavor QCD at finite temperature and the corresponding heavy quark potential at zero temperature. Static quark anti-quark sources in color singlet, octet and color averaged channels are used to probe thermal modifications of the medium. The temperature dependence of the running coupling, $α_{qq}(r,T)$, is analyzed at short and large distances and is compared to zero temperature as well as quenched calculations. In parts we also compare our results to recent findings in 3-flavor QCD. We find that the characteristic length scale below which the running coupling shows almost no temperature dependence is almost twice as large as the Debye screening radius. Our analysis supports recent findings which suggest that $χ_c$ and $ψ\prime$ are suppressed already at the (pseudo-) critical temperature and thus give a probe for quark gluon plasma production in heavy ion collision experiments, while $J/ψ$ may survive the transition and will dissolve at higher temperatures.

We use the overlap and clover action for fermions, and the Symanzik improved gluon action for 4- and 6-link loops. We compute the multiplicative renormalization of the topological charge density to one loop; this involves only the gluon part of the action. The power divergent additive renormalization of the topological susceptibility is calculated to 3 loops. Our work serves also as a test case of the techniques and limitations of lattice perturbation theory, it being the first 3-loop computation in the literature involving overlap fermions.

It is shown that the $q$-para Racah polynomials corresponding to a non-conventional truncation of the Askey-Wilson polynomials form a basis for a finite-dimensional representation of $\mathfrak{ska}_4$. The first order Heun operators defined by a degree raising condition on polynomials are shown to form a five-dimensional vector space that encompasses $\mathfrak{ska}_4$. The most general quadratic expression in the five basis operators and such that it raises degrees by no more than one is identified with the Heun-Askey-Wilson operator.

Fibre supply issues of the British Columbia log home manufacturing industry
Creators: name: Thony, Paul J.C.
Publisher: name: University of British Columbia
Year: 2009

description: British Columbia's log home manufacturing industry's fibre supply problems have been documented since 1992. To better understand the issues, an industry wide mail survey of 171 companies was conducted to assess production, sales, markets employment, fibre sources, fibre consumption, fibre costs and alternate fibre usage. The responses provided information on the current status of the industry, its fibre supply characteristics and use of alternative fibre supplies, such as insect killed, fire killed and second growth timber. A sample size of 42 resulted in a 24.6% response rate achieved in the mail survey. Over 90% of respondents reported using hand crafted production methods. The most common product category manufactured was the custom log home "not to lock up" with an average unit price of $71,100, which generated $905.36 in sales per cubic metre of fibre utilized. On average, each respondent consumed 1723 cubic metres of fibre, employed 12.5 full time equivalent personnel and produced 14.6 units per year to generate gross annual sales of $1.1 million. The major markets for BC's log home industry were the United States (46%), British Columbia (31%) and Asia (13%). Of the 55,119 cubic metres of fibre recorded as purchased by respondents, 69% was from the Vancouver and Kamloops forest regions. This fibre was primarily obtained from logging company dryland sortyards, with Douglas fir (Pseudotsuga menziesii [Mirb.] Franco) the preferred species. The weighted average delivered price of all fibre purchased was $153.67 per cubic metre. In addition to old growth timber, insect killed and second growth timber were used as alternative fibre sources with 58.5% of respondents reporting usage of these materials. Just over 26,300 cubic metres of this alternative fibre was purchased by respondents with a weighted average delivered price of $127.60 per cubic metre. The respondents' opinions indicate inconsistent fibre supply and high fibre costs had the greatest impact on the industry's performance. To resolve fibre supply issues, the log home manufacturing industry strongly favoured policy changes to existing fibre allocation programs and the creation of quota systems, over developing business relationships with organizations able to supply fibre.

description: The nature of charge stripe order and its relationship with structural phase transitions were studied using synchrotron X-ray diffraction in La$_{1.875}$Ba$_{0.125-x}$Sr$_{x}$CuO$_{4}$ ($0.05\leq x\leq 0.10$). For $x=0.05$, as temperature increased, incommensurate superlattice peaks associated with the charge order disappeared just at the structural phase transition temperature, $T_{\rm d2}$. However, for $x=0.075$ and 0.09, the superlattice peaks still existed as a short range correlation even above $T_{\rm d2}$, indicating a precursor of charge ordering. Furthermore, temperature dependences of the superlattice peak intensity, correlation length, and incommensurability for $x=0.05$ are different from those for $x=0.075$ and 0.09. These results suggest that the transition process into the charge stripe order strongly correlates with the order of the structural phase transitions. A quantitative comparison of the structure factor associated with the charge order have been also made for all the samples.

description: Price prediction is one of the examples related to forecasting tasks and is a project based on data science. Price prediction analyzes data and predicts the cost of new products. The goal of this research is to achieve an arrangement to predict the price of a cellphone based on its specifications. So, five deep learning models are proposed to predict the price range of a cellphone, one unimodal and four multimodal approaches. The multimodal methods predict the prices based on the graphical and non-graphical features of cellphones that have an important effect on their valorizations. Also, to evaluate the efficiency of the proposed methods, a cellphone dataset has been gathered from GSMArena. The experimental results show 88.3% F1-score, which confirms that multimodal learning leads to more accurate predictions than state-of-the-art techniques.

description: Bars in gas-rich spiral galaxies are short-lived. They drive gas inflows through their gravity torques, and at the same time self-regulate their strength. Their robustness has been subject of debate, since it was thought that only the resulting central mass concentrations (CMCs) were weakening bars, and only relatively rare massive CMCs were able to completely destroy them. Through numerical simulations including gas dynamics, we find that with the gas parameters of normal spiral galaxies, the CMC is not sufficient to fully dissolve the bar. But another overlooked mechanism, the transfer of angular momentum from the infalling gas to the stellar bar, can also strongly weaken the bar. In addition, we show that gravity torques are correctly reproduced in simulations, and conclude that bars are transient features, with life-time of 1-2 Gyr in typical Sb-Sc galaxies, because of the combined effects of CMCs and gravity torques, while most existing works had focussed on the CMC effects alone.

description: A globális pénzügyi és a kibontakozó gazdasági válság időszakában a munkanélküliség jelenti a legsúlyosabb társadalmi és szociális problémát az Európai Unióban és hazánkban is. A tanulmány az országos adatok és folyamatok tükrében az Észak-alföldi Régió munkanélküliséggel kapcsolatos problémáit tárja fel, különös tekintettel az agrárfoglalkoztatás helyzetére. A kutatás egyik legfontosabb következtetése, hogy minél nagyobb a munkanélküliség az adott térségben, annál nagyobb a munkanélküliek között a mezőgazdasági tevékenységgel foglalkozók aránya, azaz a mezőgazdaság szociális ellátó funkciója ezen körzetekben különösen fontos szerepet játszik. A másik fontos megállapítás, hogy a mezőgazdasági munkanélküliség mérséklése érdekében az eddiginél jóval nagyobb mértékben szükséges a régióban megtermelt mezőgazdasági termékek helyben való feldolgozása és értékesítése. Végül sürgető feladat a mezőgazdaságban dolgozók, ezen belül különösen az egyéni gazdálkodók szakképzettségének jelentős növelése. ---------------------------------------------- In the present period of global financial and developing economic crisis, unemployment counts as the most serious social problem both in the European Union and in our country. The present study compares national data and developments with the problems associated with joblessness in the Észak-Alföld Region with special attention to agricultural employment. An important conclusion of the study is that the greater the unemployment in the given region the greater the proportion of those among the unemployed occupied in agriculture, indicating the special importance of the social welfare function that agriculture provides in this regions. Another important conclusion is that much more of the locally produced crops should be locally processed and merchandised in order to ease local unemployment. Finally a significant enhancement of agricultural works’ skills, especially those of private farmers is an immediate task.

description: More and more instructors have begun using blended learning to overcome the challenges encountered during the covid-19 pandemic. However, still not much known about influential factors in students’ acceptance of such hybrid learning systems. For this purpose, a framework that includes key attributes such as; information quality and system quality, system interactivity, user satisfaction, perceived usefulness, perceived ease of use, and blended learning system use was developed. Pearson correlations were used to analyze data from 700 respondents. Findings revealed that, while there exist no significant relationships among system quality-user satisfaction and user satisfaction-use for blended learning and relatively weak, positive relations exist among perceived ease of use-use for blended learning. In addition to a low, positive relationship between perceived usefulness and use for blended learning, moderate positive correlations exist among system interactivity-user satisfaction and perceived ease of use- perceived usefulness. Finally, high positive correlations exist among information quality-user satisfaction, user satisfaction-perceived usefulness, and user satisfaction-perceived ease of use. Information quality is important in students’ satisfaction when using the blended systems. This also affects the perceived ease of use and perceived usefulness of the system. The decision-makers and institutions benefit from this study by considering only the factors leading to a successful implementation of blended learning.

description: We investigate the problem of backscattering off a time-dependent impurity in a one-dimensional electron gas. By combining the Schwinger-Keldysh method with an adiabatic approximation in order to deal with the corresponding out of equilibrium Dirac equation, we compute the total energy density (TED) of the system. We show how the free fermion TED is distorted by the backscattering amplitude and the geometry of the impurity.

Genetic diversity, population structure, mating system and pollen flow in arbutus (arbutus menziesh pursh)
Creators: name: Beland, Jaclyn Darlene
Publisher: name: University of British Columbia
Year: 2009

description: Arbutus (Arbutus menziesii Pursh) is the only broadleaved evergreen tree native to Canada. It is a member of four natural plant communities in British Columbia (BC) considered to be at risk as identified by the BC Conservation Data Centre, the main contributing factors being urban encroachment, fire suppression, grazing and exotic invasive species. Very few studies have been conducted on this species, and no data is available on pollination biology or population genetics. Amplified fragment length polymorphisms (AFLPs) were used to conduct the first genetic examination of A. menziesii in BC. The study included 10 populations spread throughout the geographic range of arbutus in BC as well as one population from Washington State. Genetic diversity estimates were low (mean H within populations = 0.094) relative to long-lived perennials on average (0.25); there were no significant differences among populations. Significant partitioning of genetic variation among populations was detected (FST = 0.15, ΦST = 0.16). This estimate was comparable to the average in long-lived perennials and frugivores-dispersed species (FST = 0.19 and 0.16, respectively). Jackknifed estimates of FST , a dendrogram of Reynolds' coancestry coefficient for all populations and a principal components analysis all suggested that the Gold River, BC population seemed to differ more from other populations, although this trend was not statistically significant. Isolation by distance was significant based on kinship coefficients (p < 0.01): half-sibs were approximately three metres apart. Mating system analysis of the Amelia Island, BC population revealed a high outcrossing rate (0.97), although 10-20% of mating events were attributed to biparental inbreeding. Pollen flow in this population was also investigated using a paternity analysis. Due to the low genetic variability detected in this species as well as the significant biparental inbreeding, the ability to confidently assign paternity was limited. Comparison of paternity assignment at LOD score threshold values of 4 and 5 revealed the characteristic leptokurtic distribution of pollen in many other plant species. The information generated from this investigation is discussed with respect to conservation strategies, and future directions in the study of the genetics of arbutus are suggested.
Narrow Width of Penta-Quark Baryons in QCD String Theory

description: Using the QCD string theory, we investigate the physical reason of the narrow width of penta-quark baryons in terms of the large gluonic-excitation energy. In the QCD string theory, the penta-quark baryon decays via a gluonic-excited state of a baryon and meson system, where a pair of Y-shaped junction and anti-junction is created. On the other hand, we find in lattice QCD that the lowest gluonic-excitation energy takes a large value of about 1 GeV. Therefore, in the QCD string theory, the decay of the penta-quark baryon near the threshold is considered as a quantum tunneling process via a highly-excited state (a gluonic-excited state), which leads to an extremely narrow decay width of the penta-quark system.

description: A Dunaszigeten 300 anyával működő gazdaság eredményességében kulcskérdés a termelési költségek csökkentése, mindenekelőtt a takarmányozás, az egyéb (áram, tejvizsgálat, bérleti díjak stb.), valamint a munkabérköltségek mérséklése. A bevételi oldalon növekvő jelentőségű – a kecsketej- és gidaértékesítés mellett – egyre nagyobb arányban a sajtértékesítés. A jövőt illetően a kockázati tényezők és a fejlesztési lehetőségek számbavétele, a helyi lehetőségek hasznosítása, s az egészségre kedvező hatású tej és sajt megismertetése a meghatározó. ------------------------------------ The success of the farm using 300 mother goats depended on the reduction of production costs including especially that of fodder and others (electricity, milk testing, rent, etc) and the moderation of taxes and dues on labour costs. On the income side selling of milk and goat kid apart merchandising goat cheese is increasingly popular. As for the future it is essential to assess the risk factors and local development opportunities and to bring the attention of consumers to the favourable health effects of goat milk and cheese.
Creation and detection of mobile and non-local spin-entangled electrons

description: We present electron spin entanglers--devices creating mobile spin-entangled electrons that are spatially separated--where the spin-entanglement in a superconductor present in form of Cooper pairs and in a single quantum dot with a spin singlet groundstate is transported to two spatially separated leads by means of a correlated two-particle tunneling event. The unwanted process of both electrons tunneling into the same lead is suppressed by strong Coulomb blockade effects caused by quantum dots, Luttinger liquid effects or by resistive outgoing leads. In this review we give a transparent description of the different setups, including discussions of the feasibility of the subsequent detection of spin-entanglement via charge noise measurements. Finally, we show that quantum dots in the spin filter regime can be used to perform Bell-type measurements that only require the measurement of zero frequency charge noise correlators.

description: We present here a study of selection of rhombic patterns close to a bicritical point at the onset of primary surface instability in viscous fluids under two-frequency vertical vibration. Rhombic patterns appear to be natural at the primary instability in the form of a bicritical point if the ratio of driving frequencies is selected properly. We present two different patterns which may be accessible in a Faraday experiment.

description: It is shown that there exists a possibility of amplification of amplitudes of quantum pion modes with low momenta in the late time of chiral phase transition by using the Gaussian wave functional approximation in the O(4) linear sigma model. It is also shown that the amplification occurs in the mechanism of the resonance by forced oscillation as well as the parametric resonance induced by the small oscillation of the chiral condensate. These mechanisms are investigated in both the case of spatially homogeneous system and the spatially expanded system described by the Bjorken coordinate.
