description: It is rigorously proved that ideal memcapacitors and meminductors are not passive or lossless devices, nor are they satisfying the weaker notion of cyclo-passivity, which arises when dropping the requirement of non-negativity of the storage function. Equivalently, this implies that there exist excitation profiles that allow to extract more energy from the device than it is supplied with; so that their energy conversion efficiency exceeds 100%. This means that ideal memcapacitors and meminductors constitute so-called overunity systems. An illustrative mechanical analogue is provided that explicitly confirms this property. Hence, the question arises if ideal memcapacitors and meminductors will just remain some mathematical toys or artefacts.

Testing Supersymmetry with Lepton Flavor Violating tau and mu decays
Creators: name: Arganda, E.
name: Herrero, M. J.
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In this work the following lepton flavor violating $τ$ and $μ$ decays are studied: $τ^- \to μ^- μ^- μ^+$, $τ^- \to e^- e^- e^+$, $μ^- \to e^- e^- e^+$, $τ^- \to μ^- γ$, $τ^- \to e^- γ$ and $μ^- \to e^- γ$. We work in a supersymmetric scenario consisting of the minimal supersymmetric standard model particle content, extended by the addition of three heavy right handed Majorana neutrinos and their supersymmetric partners, and where the generation of neutrino masses is done via the seesaw mechanism. Within this context, a significant lepton flavor mixing is generated in the slepton sector due to the Yukawa neutrino couplings, which is transmited from the high to the low energies via the renormalization group equations. This slepton mixing then generates via loops of supersymmetric particles significant contributions to the rates of $l_j \to 3 l_i$ and the correlated $l_j \to l_i γ$ decays. We analize here in full detail these rates in terms of the relevant input parameters, which are the usual minimal supergravity parameters and the seesaw parameters. For the $l_j \to 3 l_i$ decays, a full one-loop analytical computation of all the contributing supersymmetric loops is presented. This completes and corrects previous computations in the literature. In the numerical analysis compatibility with the most recent experimental upper bounds on all these $τ$ and $μ$ decays, with the neutrino data, and with the present lower bounds on the supersymmetric particle masses are required. Two typical scenarios with degenerate and hierarchical heavy neutrinos are considered. We will show here that the minimal supergravity and seesaw parameters do get important restrictions from these $τ$ and $μ$ decays in the hierarchical neutrino case.

Characterization of the chloroplast genome of selected dinoflagellates : mini- and digenic circles in adenoides eludens
Creators: name: Nelson, Martha
Publisher: name: University of British Columbia
Year: 2009

description: DNA was isolated from three species of peridinin-containing dinoflagellate (Scrippsiella trochoidea, Prorocentrum micans and Adenoides eludens) and run through a CsCl density gradient to separate it into main (nuclear) and satellite (organellas) fractions. The fractions were hybridized with chloroplast gene probes. This showed that chloroplast genes are found on discrete pieces of satellite 2 DNA in two species: small pieces (~1.5 kb) in Prorocentrum micans, and larger pieces (5 kb, 9 kb and larger) in Adenoides eludens. These results were similar to those of Zhang et al. (1999), who discovered unigenic minicircles in the chloroplast DNA of the peridinin-containing dinoflagellate Heterocapsa triquetra. Sequence data for chloroplast genes psbA, psbC, and psbD were obtained from Adenoides eludens. Outward directed polymerase chain reaction (PCR) primers were designed for these genes to amplify minicircles, and products of 4.1 to 5.2 kb were obtained, indicating the likely presence of minicircles in the chloroplast DNA of this species. The outward PCR products from the psbA reaction were cloned. Sequencing revealed that clones of the psbA minicircle were different from one another, unlike the results of previous studies that showed that the sequence of minicircles containing the same gene are the same (Zhang et al. 1999, Zhang et al. 2002, Barbrook and Howe 2000, Barbrook et al. 2001, Hiller 2001). The clones did share some sequence identity, however, including some secondary structure, repeated motifs, and a 200 base pair conserved region. The length of the fully sequenced region was 4300 base pairs, making the minicircle 4489 base pairs in total. Outward and inward directed PCR primers from three chloroplast genes (psbA, psbC, and psbD) were used in all combinations to amplify many products ranging in size from 5.0 to 6.5 kb. The product resulting from the psbD Ro and psbA Fi primer pair was cloned. The sequence of the ends of three of these clones revealed that both of the gene ends (psbD and psbA) were present and that the non-coding regions of the clones were different from one another. Further experiments using nested PCR showed some similarities between these products and the psbA minicircles. This result implies that digenic circles may exist in Adenoides eludens.

description: We demonstrate a first order metal-insulator phase transition in the repulsive, fully frustrated, single-band Hubbard model as a function of the coupling to a fermion bath. Time dependent manipulation of the bath coupling allows switching between metallic and insulating states both across the phase transition and within the coexistence region. We propose a simple nanoelectronic device for experimentally realizing dynamic control of the bath coupling. Analysis of the device characteristics shows that it can act as a two-terminal memristor.

description: This paper investigates the economic significance of informal borrowing between friends and relatives in rural China. Guided by an economic model of household-production interactions, we provide results from a survey of over 1,500 households including GLM and Logistic regression results. We find evidence of a ‘small farm bias’ in the use of informal credit, but we cannot generalize this to credit rationing as a matter of course. In part we believe that a preference for informal borrowing is related to some forms of credit rationing, spillover effects and collateral as some literature suggests, but our results suggest that by no means are these mutually exclusive or exhaustive.

description: The deregulation of Ghana’s domestic cocoa supply chain that took place in the early 1990s was expected to bring competition among different private buyers and to generate a number of production incentives to the farmers. Most notably, it was expected that competition would emerge by means of price bonuses and/or premiums over the guaranteed price. However, this paper finds that price based competition mechanisms did not develop in the resulting domestic cocoa value chain. Rather, the now increasing numbers of Licensed Buying Companies compete for cocoa supplies based on the provision of different services to farmers. The availability of a number of outlets offers farmers the option to choose among those that can provide cash as well as credit. The cash payment and credit for inputs offered to attract cocoa sales mainly benefit liquidity-constrained farmers, enabling them to invest in productive inputs. Since cash constrained farmers are likely to be the poorest as measured by simple welfare indicators, liberalization may be seen to have had a progressive impact on Ghana’s cocoa farmers.

description: In a recent paper [Beige, Knight, and Vitiello, quant-ph/0404160], we showed that a large number N of particles can be cooled very efficiently using a bichromatic interaction. The particles should be excited by red-detuned laser fields while coupling to the quantized field mode inside a resonant and leaky optical cavity. When the coupling constants are for all particles the same, a collective behavior can be generated and the cooling rate can be as large as square root of N times the single-particle coupling constants. Here we study the algebraic structure of the dynamics and the origin of the collective cooling process in more detail.

description: In contrast to molecular gases, granular gases are characterized by inelastic collisions and require therefore permanent driving to maintain a constant kinetic energy. The kinetic theory of granular gases describes how the average velocity of the particles decreases after the driving is shut off. Moreover it predicts that the rescaled particle velocity distribution will approach a stationary state with overpopulated high-velocity tails as compared to the Maxwell-Boltzmann distribution. While this fundamental theoretical result was reproduced by numerical simulations, an experimental confirmation is still missing. Using a microgravity experiment which allows the spatially homogeneous excitation of spheres via magnetic fields, we confirm the theoretically predicted exponential decay of the tails of the velocity distribution.

description: Previous studies commonly assume that the effects of introducing and ending cereal price subsidies on the poor’s nutrient intakes are symmetric. We question the assumption of symmetry and show that the poor’s nutrient intakes respond asymmetrically to declines and increases in the price of cereal in China. Our results imply that introducing cereal price subsidies can increase the poor’s total energy intake by increasing their calorie intakes from fat and protein, and that ending such subsidies would insignificantly affect the poor’s total energy intake; however, it may further increase their calorie intakes from fat and protein.

Impact of Land Institutional Factors on Farm Management and Soil Quality

description: Soil quality has important implications for sustainable agricultural development and food self-sufficiency in many developing countries. A decrease in soil nutrient stocks, one of the components of soil quality, necessitates more inputs and greater management skills in order to compensate for the reduction in nutrients availability. This is why the interaction of agricultural development and soil quality management attracts widespread attention from researchers. Applying plot level data on input/output, and a selected number of soil quality indicators and farm household level information, from the three villages, this paper examines the impact of land fragmentation and land tenure on soil management, the dynamic component of soil quality, crop husbandry and rice yield at plot level. A 2SLS econometric approach is applied to simultaneously estimate the interlinked relationships between these variables. From these results we conclude that land fragmentation does play a role in farm management practices and decisions. The land tenure status of a plot does not affect crop husbandry decisions on labor and herbicide use. Farmers on rented-in plots do, however, use more chemical fertilizers (phosphorus and potassium). This implies that farmers care more about short-term yields than about the built-up of long-term soil productivity. In order to sustain long-term soil productivity, measures should be taken to ensure that the prices for renting land reflect such soil investments.

description: Algorithmic latency in speech processing is dominated by the frame length used for Fourier analysis, which in turn limits the achievable performance of magnitude-centric approaches. As previous studies suggest the importance of phase grows with decreasing frame length, this work presents a systematical study on the contribution of phase and magnitude in modern Deep Neural Network (DNN)-based speech enhancement at different frame lengths. Results indicate that DNNs can successfully estimate phase when using short frames, with similar or better overall performance compared to using longer frames. Thus, interestingly, modern phase-aware DNNs allow for low-latency speech enhancement at high quality.

Alpha particle production by molecular single-particle effect in reactions of $^{9}$Be just above the Coulomb barrier

description: The $α$-particle production in the dissociation of $^{9}$Be on $^{209}$Bi and $^{64}$Zn at energies just above the Coulomb barrier is studied within the two-center shell model approach. The dissociation of $^{9}$Be on $^{209}$Bi is caused by a molecular single-particle effect (Landau-Zener mechanism) before the nuclei reach the Coulomb barrier. Molecular single-particle effects do not occur at that stage of the collision for $^{9}$Be+$^{64}$Zn, and this explains the absence of fusion suppression observed for this system. The polarisation of the energy level of the last neutron of $^{9}$Be and, therefore the existence of avoided crossings with that level, depends on the structure of the target.

description: Modern environmental issues imply that decision-makers have the capacity to take into account possibly conflicting information from distinct domains, such as science and economics. As the development of technology increases the temporal and spatial scopes of risks, decision-makers can no longer consider economic and scientific information separately but should encourage experts to work together. Boundary organizations, institutions that cross the gap between two different domains, are able to act beyond the boundaries while remaining accountable to each side (Guston, 2001). By encouraging a flow of information across the boundaries, they permit an exchange to take place, while maintaining the authority of each domain (Cash et al., 2003; Clark et al., 2002). The goal is to simulate boundary organizations to assess their impact on the diffusion of experts’ opinions. The hypothesis tested is whether the existence of a boundary organization eases the decision-making process by reducing the number of opinions expressed. The methodology relies on a multi-agent system based on a model of continuous opinion dynamics (Deffuant et al., 2001) extended over two dimensions. The world is defined by two parameters: the uncertainty, that reflects the possible zone of discussion between experts, and the exchange, which represents the openness of discussions. Agents are described by credibility and conviction: the credibility represents how much other agents may be influenced by an agent, and the conviction represents the resistance of an agent to changing its position. Two kinds of agents are left free to interact, modifying their position in their domain (dimension) through one-to-one exchanges. Agents called borgs are introduced: open to trans-disciplinary discussion, they are able to exchange on both dimensions. The results show that the range of expressed opinions is significantly reduced, even at low levels of experts involved in the boundary organization.

description: Active matter systems exhibit rich emergent behavior due to constant injection and dissipation of energy at the level of individual agents. Since these systems are far from equilibrium, their dynamics and energetics cannot be understood using the framework of equilibrium statistical mechanics. Recent developments in stochastic thermodynamics extend classical concepts of work, heat, and energy dissipation to fluctuating non-equilibrium systems. We use recent advances in experiment and theory to study the non-thermal dissipation of individual light-activated self-propelled colloidal particles. We focus on characterizing the transition from thermal to non-thermal fluctuations and show that energy dissipation rates on the order of $\sim k_BT/$s are measurable from finite time series data.

The answer is still not as simple as that because “interesting” in business terms is not only about today, but very much about tomorrow. By the end of 2007 it was obvious that the Romanian insurance market is far from calming down. Not only that for the time being change is still the main real constant in use, but figures show that the market environment becomes more challenging than ever these days. The market situation showed that this allegation it was by that time more likely to be true than ever.

description: Since cell-based virus neutralization assays are still the gold standard to assess a patient's immune protection against a given virus, they are of utmost importance for serodiagnosis, convalescent plasma therapy, and vaccine development. Monitoring the emergence and characteristics of neutralizing antibodies in an outbreak situation, confirming neutralizing antibodies as correlates of protection from infection and testing vaccine-induced potency of neutralizing antibody responses, quests for automated, fast, and parallel neutralization assays. We developed an impedance-based sensor platform (electric cell-substrate impedance sensing, ECIS) providing time-resolved monitoring of the host cell response to viral pseudotypes. For validation, the impedance assay was compared with state-of-the-art quantification of virus-induced reporter protein expression as an independent indicator of virus infection and neutralization. Vesicular stomatitis virus (VSV) derived pseudoviruses encoding the green fluorescent protein (GFP) as reporter and the autologous G protein (VSV-G) for the initial binding to the host cell membrane were used for monitoring of HEK293T cell infection and neutralization with both, impedance and optical readout. Virus-induced cytopathic effects (CPE) were detectable for low pseudotype concentrations (multiplicity of infection 1) in time-resolved impedance profiles as soon as 5–10 h after infection in a concentration-dependent manner. Neutralization efficacy of α-VSV-G antibodies was determined from impedance time courses and IC50 values compared favorably with fluorescence measurements of virus-borne GFP expression. Sera of convalescent COVID-19 patients were tested successfully for SARS-CoV-2 neutralizing antibodies by incubating VSV, pseudotyped with the SARS-CoV-2 spike protein, with different sera before host cell exposure and impedance recordings. In summary: (i) ECIS monitoring was successfully applied to detect virus-mediated cell infection and neutralization; (ii) Impedance-based monitoring allows reducing the assay time to 5–10 h; and (iii) the platform is easily adapted to other virus-based diseases and scalable to high-throughput.

We demonstrate that strong but finite on-site interaction U along with a comparable nearest-neighbor repulsion V result in a thermodynamically stable supersolid ground state just above half-filling, and that the checker-board crystal is unstable for smaller V, and for any V just below half-filling. The interplay between these two interaction energies results in a rich phase diagram which is studied in detail using quantum Monte Carlo methods.

Screening of biflavonoid compounds and British Columbian bryophytes for antiviral activity against potato virus X
Creators: name: Hillhouse, Brian Jason
Publisher: name: University of British Columbia
Year: 2009

description: Plant viruses are responsible for causing significant losses to the agricultural industry. Recent investigations of antiviral compounds have suggested that biflavonoids may be a group of compounds which cause powerful inhibition to a broad spectrum of viral pathogens. Due to the high content of biflavonoids reported in bryophytes, this project has screened 50 bryophyte samples which represent 41 species for Potato Virus X (PVX) inhibition using a local lesion assay in Chenopodium quinoa. As a result of this screening, bryophytes have been identified as a prominent antiviral group; 29 of the 41 species were shown to cause greater than 75% inhibition when tested at 9.1 mg/mL. In addition to screening bryophyte extracts, several biflavonoid compounds were tested directly. When tested at 1.38 mg/mL robustaflavone and hinokiflavone where shown to be highly antiviral and exhibited PVX inhibitions of 85% and 78% respectively. Amentoflavone-7,4',4'trimethyl ether showed a marginal PVX inhibition of 29% and amentoflavone did not inhibit PVX at this concentration. Several compounds from the Columbian medicinal plant Iryanthera megistophylla have also been screened for inhibition of PVX. Of these compounds, iryanterin K, cinchonain Ib, cinchonain Ia, procyanidin B-2 and cinchonain IIa have been shown to be highly active against PVX when tested at 9.1 mg/mL.

description: Hungary is the pioneer of the European Equestrian Tourism. Several thousands foreign tourists visited specific equestrian programmes already in the 1960’s and 1970’s. At the same times some hundred thousands of holiday tourists visited equestrian shows and programs organised in different areas of our country. From the beginning of the 1990’s equestrian enterprises (pensions, stables, specialized equestrian services) have been established. The equestrian tourism enterprises are well represented all over the country. They are well organised, the Hungarian Equestrian Tourism Association integrates 80% of equestrian tourism enterprises. Uniquely in Europe, the voluntary professional qualification, called “the horseshoe qualification system” started in 1998. The most common quality categories are for entrepreneurs are 3 or 2 or 1 horseshoe. The system of Tourism Destination Management organizations could provide the background for the development of equestrian tourism enterprises as well. At local level these needs would be product development, the quality control and quality management, at regional level the most important aims could be the development of regional equestrian image and increasing the attractiveness of this image, finally hardening the positions of equestrian tourism destination.

The first cycle of application of the open method of co-ordination (OMC) to the 3% objective provided an overview of the Member States policies in a number of areas, facilitated mutual learning and led to a number of policy recommendations adopted by CREST in October 2004. The current regional benchmarking practice is made within a 6th Framework Programme project called Cognac, which is the acronym for Coordination of R&D&I policies and their coherence with other policies in Newly Acceded Countries. The project is focusing on two priority subjects: public research spending and policy mixes and SMEs and research. The project was supported within the first cycle of the RTD-OMC NET call. The benchmarking exercise tries to show the differences in the performance of participating regions. It supposed to choose the best regions at NUTS II level by the two priority topic of the project: “Public research spending and policy mixes” and “SMEs and research”. Geographically the analysis covers the area of the eight partnering regions.

description: Interacting many-body systems with explicitly accessible spatio-temporal correlation functions are extremely rare, especially in the absence of integrability. Recently, we identified a remarkable class of such systems and termed them dual-unitary quantum circuits. These are brick-wall type local quantum circuits whose dynamics are unitary in both time and space. For these systems the spatio-temporal correlation functions are non-trivial only at the edge of the causal light cone and can be computed in terms of one-dimensional transfer matrices. Dual-unitarity, however, requires fine-tuning and the degree of generality of the observed dynamical features remained unclear. Here we address this question by introducing arbitrary perturbations of the local gates. Considering fixed perturbations, we prove that for a particular class of unperturbed elementary dual-unitary gates the correlation functions are still expressed in terms of one-dimensional transfer matrices. These matrices, however, are now contracted over generic paths connecting the origin to a fixed endpoint inside the causal light cone. The correlation function is given as a sum over all such paths. Our statement is rigorous in the "dilute limit", where only a small fraction of the gates is perturbed, and in the presence of random longitudinal fields, but we provide theoretical arguments and stringent numerical checks supporting its validity even in the clean case and when all gates are perturbed. As a byproduct, in the case of random longitudinal fields -- which turns out to be equivalent to certain classical Markov chains -- we find four types of non-dual-unitary(and non-integrable) interacting many-body systems where the correlation functions are exactly given by the path-sum formula.

description: We construct tree-level four-particle open-string amplitudes relevant to dilepton and diphoton production at hadron colliders. We expand the amplitudes into string resonance (SR) contributions and compare the total cross-section through the first SR with the $Z^{\prime}$ search at the Tevatron. We establish a current lower bound based on the CDF Run I results on the string scale to be about $1.1-2.1$ TeV, and it can be improved to about $1.5-3$ TeV with 2 fb$^{-1}$. At the LHC, we investigate the properties of signals induced by string resonances in dilepton and diphoton processes. We demonstrate the unique aspects of SR-induced signals distinguishable from other new physics, such as the angular distributions and forward-backward asymmetry. A 95% C.L. lower bound can be reached at the LHC for $M_S>8.2-10$ TeV with an integrated luminosity of 300 fb$^{-1}$. We emphasize the generic features and profound implications of the amplitude construction.

description: We investigate the phase diagram of the heterostructural solid solution (InxGa1-x)2O3 both computationally, by combining cluster expansion and density functional theory, and experimentally, by means of TEM measurements of pulsed laser deposited (PLD) heteroepitaxial thin films. The shapes of the Gibbs free energy curves for the monoclinic, hexagonal and cubic bixbyite alloy as a function of composition can be explained in terms of the preferred cation coordination environments of indium and gallium. We show by atomically resolved STEM that the strong preference of indium for six-fold coordination results in ordered monoclinic and hexagonal lattices. This ordering impacts the configurational entropy in the solid solution and thereby the (InxGa1-x)2O3 phase diagram. The resulting phase diagram is characterized by very limited solubilities of gallium and indium in the monoclinic, hexagonal and cubic ground state phases respectively but exhibits wide metastable ranges at realistic growth temperatures. On the indium rich side of the phase diagram a wide miscibility gap is found, which results in phase separated layers. The experimentally observed indium solubilities in the PLD samples are in the range of x=0.45 and x=0.55 for monoclinic and hexagonal single-phase films, while for phase separated films we find x=0.5 for the monoclinic phase, x=0.65-0.7 for the hexagonal phase and x>0.9 for the cubic phase. These values are consistent with the computed metastable ranges for each phase.

description: Phonon interactions in solid-state photonics systems cause intrinsic quantum decoherence and often present the limiting factor in emerging quantum technology. Due to recent developments in nanophotonics, exciton-cavity structures with very strong light-matter coupling rates can be fabricated. We show that in such structures, a new regime emerges, where the decoherence is completely suppressed due to decoupling of the dominant phonon process. Using a numerically exact tensor network approach, we perform calculations in this non-perturbative, non-Markovian dynamical regime. Here, we identify a strategy for reaching near-unity photon indistinguishability and also discover an interesting phonon-dressing of the exciton-cavity polaritons in the high-Q regime, leading to multiple phonon sidebands when the light-matter interaction is sufficiently strong.

description: Economic slowdown and downturn creates new situation for every organisation, no one can avoid facing to new situation created by the global financial-, and economic crisis. All of the organisational function should reconsider its own role within the company due to the new circumstances, Accounting and Mangement Accounting can not be exception, but they have more complex and emphasized role in these difficult times. In the following paper I can not avoid to mention some general statement about importance of accounting and accounting principles, while there are a number of critical accounting and financial reporting issues that accountants and auditors should consider. In the framework of the paper I can not face with all relevant issues of the topic, but after some general statement I would like to highlight some special area regarding to management accounting, which can be more important during these challenging time for decision makers and accountants. Regarding to balance sheet analysis its important to mention current debate about fair value comparing with historical cost from accounting point of view, on the other hand from the view of management reporting system I would like to highlight the importance of working-capital indicators. More practical topic is the crucial role of budgeting and forecasting during economic downturns, and at the end I would like to show why it is more important monitoring price variance and indirect cost allocation in these uncertain business circumstances.

description: `How do our ideas about quantum mechanics affect our understanding of spacetime?' This familiar question leads to quantum gravity. The complementary question is also important: `How do our ideas about spacetime affect our understanding of quantum mechanics?' This short abstract of a talk given at the Gafka2004 conference contains a very brief summary of some of the author's papers on generalizations of quantum mechanics needed for quantum gravity. The need for generalization is motivated. The generalized quantum theory framework for such generalizations is described and illustrated for usual quantum mechanics and a number of examples to which it does not apply. These include spacetime alternatives extended over time, time-neutral quantum theory, quantum field theory in fixed background spacetime not foliable by spacelike surfaces, and systems with histories that move both forward and backward in time. A fully four-dimensional, sum-over-histories generalized quantum theory of cosmological geometries is briefly described. The usual formulation of quantum theory in terms of states evolving unitarily through spacelike surfaces is an approximation to this more general framework that is appropriate in the late universe for coarse-grained descriptions of geometry in which spacetime behaves classically. This abstract is unlikely to be clear on its own, but references are provided to the author's works where the ideas can be followed up.
