description: The lag situation of small farmers forced to seek alternative crops that are more profitable. Because of this we assessed the economic viability of the production of wild tomato (Solanum lycopersicum L.) organic plastic covers low cost, quality and quantity for the product, preserving the environment and achieving economic and social benefits. The project was finished in productive Township Teziutlán, Puebla in an area of 100 m2, obtaining 1299 kg per cycle on average 2595 kg per year, the project was to small backyard producers, as the wild tomato is traded regional, and the cost of this usually remains at $ 18.00 per kilogram price being more stable and higher than conventional tomatoes. In the financial analysis yielded the following indicators: Net Present Value $ 60,452.99, benefit-cost $ 1.79, IRR 19.03% so it is concluded that the project is viable.

description: In Mexico, the municipal governments have acquired the character of government with full rights and own competition since the constitutional reforms of 1999. In the same reforms period, the municipality has grown significantly in numbers of employees, management of economic resources, political influence, and incidence in older areas of the political, economic and social life. (Morales, 2008). However the reforms, in general terms, haven’t increased their institutional capacity; in such a way that in many locations in Mexico, poor municipal management has generated limited economic, political, social and environmental effects in the local municipalities development in Mexico.

description: Quantum error mitigation has been proposed as a means to combat unwanted and unavoidable errors in near-term quantum computing without the heavy resource overheads required by fault tolerant schemes. Recently, error mitigation has been successfully applied to reduce noise in near-term applications. In this work, however, we identify strong limitations to the degree to which quantum noise can be effectively `undone' for larger system sizes. Our framework rigorously captures large classes of error mitigation schemes in use today. By relating error mitigation to a statistical inference problem, we show that even at shallow circuit depths comparable to the current experiments, a superpolynomial number of samples is needed in the worst case to estimate the expectation values of noiseless observables, the principal task of error mitigation. Notably, our construction implies that scrambling due to noise can kick in at exponentially smaller depths than previously thought. They also impact other near-term applications, constraining kernel estimation in quantum machine learning, causing an earlier emergence of noise-induced barren plateaus in variational quantum algorithms and ruling out exponential quantum speed-ups in estimating expectation values in the presence of noise or preparing the ground state of a Hamiltonian.

Superconducting qubits : survey and theoretical investigations for solid state quantum computing
Creators: name: Gupta, Santosh Kumar
Publisher: name: University of British Columbia
Year: 2010

description: Superconducting qubits have in recent years become a promising candidate for the implementation of a quantum computer due to their design flexibility, good protection from decohering elementary excitations, and availability of well developed fabrication and measurement techniques. Superconducting flux qubits, for which the effect of offset charge noise is reduced due to the fact that the Josephson energy dominates over the charging energy, correspond to one of the proposed means of designing a superconducting qubit. A nonlinear dispersive readout scheme of flux qubits involving a DC SQUID magnetometer that avoids the effects of on-chip dissipation can be readily implemented, yielding high contrast output for single qubit readout. Coupling schemes via nonlinear Josephson elements have also been realized. On the other hand, while the means of isolating superconducting qubits from external noise sources has been found, the mechanisms by which they undergo relaxation and decoherence due to intrinsic noise sources in the junctions themselves are not very well understood, and the question of how to deal with these noise sources remains unanswered in the general case. Other questions deal with the problem of experimentally observing entanglement in an array of coupled superconducting qubits, and finding the means by which the existence of entanglement in a typical laboratory setup may to some extent be verified by measurements on a global scale. Following a brief introductory review, we will first investigate the influence of a Two-Level Fluctuator on a DC SQUID driven by a finite current bias. Then we introduce a directly measurable signature of multiqubit entanglement for a large system of qubits and show that it is compatible to a recently introduced measure of global entanglement.
The formation of neutron star systems through accretion-induced collapse in white-dwarf binaries

description: The accretion-induced collapse (AIC) scenario was proposed 40 years ago as an evolutionary end state of oxygen-neon white-dwarfs (ONe WDs), linking them to the formation of neutron star (NS) systems. However, there has been no direct detection of any AIC event so far, even though there exists a lot of indirect observational evidence. Meanwhile, the evolutionary pathways resulting in NS formation through AIC are still not well investigated. In this article, we review recent studies on the two classic progenitor models of AIC events, i.e., the single-degenerate model (including the ONe WD+MS/RG/He star channels and the CO WD+He star channel) and the double-degenerate model (including the double CO/ONe WD channels and the ONe WD+CO WD channel). Recent progress on these progenitor models is reviewed, including the evolutionary scenarios, the initial parameter space and the related objects. For the single-degenerate model, the pre-AIC systems could potentially be identified as supersoft X-ray sources, symbiotics and cataclysmic variables, whereas the post-AIC systems could be identified as low-/intermediate-mass X-ray binaries and the resulting low-/intermediate-mass binary pulsars, most notably millisecond pulsars. For the double-degenerate model, the pre-AIC systems are close double WDs, whereas the post-AIC systems are isolated NSs with peculiar properties. We also review the predicted rates of AIC events, the mass distribution of NSs, and the gravitational wave (GW) signals from double WDs that are potential GW sources in the Galaxy in the context of future space-based GW detectors. Recent theoretical and observational constraints on the detection of AIC events are summarized. In order to confirm the existence of the AIC process, and resolve this long-term issue presented by current stellar evolution theories, more numerical simulations and observational identifications are required.

description: Important goals of RHIC and LHC experiments with ion beams include the creation and study of new forms of matter, such as the Quark Gluon Plasma. Heavy quark production and attenuation will provide unique tomographic probes of that matter. We predict the suppression pattern of open charm and beauty in $Au+Au$ collisions at RHIC and LHC energies based on the DGLV formalism of radiative energy loss. A cancelation between effects due to the $\sqrt{s}$ energy dependence of the high $p_T$ slope and heavy quark energy loss is predicted to lead to surprising similarity of heavy quark suppression at RHIC and LHC.

description: We study the spin- 1/2 two and three dimensional Orbital Compass Models relevant to the problem of orbital ordering in transition metal oxides. We show that these systems display self-dualities and novel (gauge-like) discrete sliding symmetries. An important and surprising consequence is that these models are dual to (seemingly unrelated) recently studied models of p+ip superconducting arrays. The duality transformations are constructed by means of a path-integral representation in discretized imaginary time and considering its Z_{2} spatial reflection symmetries and space-time discrete rotations, we obtain, in a transparent unified geometrical way, several dualities. We also introduce an alternative construction of the duality transformations using operator identities. We discuss the consequences of these dualities for the order parameters and phase transitions of the orbital compass model and its generalizations, and apply these ideas to a number of related systems.

description: In the nearby galaxy NGC 4258, the well-modeled orbital motion of H$_2$O masers about its supermassive black hole provides the means to measure a precise geometric distance. As a result, NGC 4258 is one of a few "geometric anchors" available to calibrate the true luminosities of stellar distance indicators such as the Tip of the Red Giant Branch (TRGB) or the Cepheid Leavitt law. In this paper, we present a detailed study of the apparent magnitude of the TRGB within NGC 4258 using publicly-available HST observations optimally situated in the gas- and dust-free halo along the minor axis, spanning distances ranging from 8 to 22 kpc in projected galactocentric radius. We undertake a systematic evaluation of the uncertainties associated with measuring the TRGB in this galaxy, based on an analysis of 54 arcmin$^2$ of HST/ACS imaging. After quantifying these uncertainties, we measure the TRGB in NGC 4258 to be F814W$_0$ = 25.347 $\pm$ 0.014(stat) $\pm$ 0.042(sys) mag. Combined with a recent 1.5% megamaser distance to NGC 4258, we determine the absolute luminosity of the TRGB to be $M_{F814W}^{TRGB}$ = -4.050 $\pm$ 0.028(stat) $\pm$ 0.048(sys) mag. This new calibration agrees to better than 1% with an independent calibration presented in Freedman et al. (2019, 2020) that was based on detached eclipsing binaries (DEBs) located in the LMC.

description: The Adaptive Large Neighborhood Search (ALNS) algorithm has shown considerable success in solving combinatorial optimization problems (COPs). Nonetheless, the performance of ALNS relies on the proper configuration of its selection and acceptance parameters, which is known to be a complex and resource-intensive task. To address this, we introduce a Deep Reinforcement Learning (DRL) based approach called DR-ALNS that selects operators, adjusts parameters, and controls the acceptance criterion throughout the search. The proposed method aims to learn, based on the state of the search, to configure ALNS for the next iteration to yield more effective solutions for the given optimization problem. We evaluate the proposed method on an orienteering problem with stochastic weights and time windows, as presented in an IJCAI competition. The results show that our approach outperforms vanilla ALNS, ALNS tuned with Bayesian optimization, and two state-of-the-art DRL approaches that were the winning methods of the competition, achieving this with significantly fewer training observations. Furthermore, we demonstrate several good properties of the proposed DR-ALNS method: it is easily adapted to solve different routing problems, its learned policies perform consistently well across various instance sizes, and these policies can be directly applied to different problem variants.

description: A test of quantumness is a protocol where a classical user issues challenges to a quantum device to determine if it exhibits non-classical behavior, under certain cryptographic assumptions. Recent attempts to implement such tests on current quantum computers rely on either interactive challenges with efficient verification, or non-interactive challenges with inefficient (exponential time) verification. In this paper, we execute an efficient non-interactive test of quantumness on an ion-trap quantum computer. Our results significantly exceed the bound for a classical device's success.

For one-qubit fingerprinting of two-bit messages, we prepare `tetrahedral' qubit states experimentally and show that they meet the requirements for quantum fingerprinting to exceed the classical capability. We prove that shared entanglement permits 100% reliable quantum fingerprinting, which will outperform classical fingerprinting even with arbitrary amounts of shared randomness.

Tanulmányunkban ennek a mondhatni speciális szegmensnek a táplálkozási szokásait vettük górcső alá. Fókuszcsoportos vizsgálatunk során arra kerestük a választ, hogy a román és erdélyi fiatalok étkezési kultúrája, milyen hasonlóságokat illetve különbségeket mutat, valamint hogy az erdélyi gasztronómia mennyire őrizte meg magyaros jellegét és milyen mértékben épültek be a román étkezési hagyományok. Lehet-e külön fogyasztói szegmensként kezelni az erdélyi magyarokat, vagy elegendő, ha „egy kalap alá vesszük” őket a román fogyasztókkal. Bemutatásra kerültek a fiatalok otthoni és házon kívüli étkezési szokásai, az élelmiszerfogyasztásukat befolyásoló tényezők, kedvenc élelmiszermárkáik és az egészséges táplálkozással kapcsolatos attitűdjeik. ------------------------------------------------------------------------------------- In recent years the adolescents, who are neither adults nor already children, still depend on their parents. In spite of these, they form a group with several self-sufficient, varied consumer demands and decisions. In our study we examined the eating habits of this special segment. During our focus group testing we tried to find the answers to the following questions: • What are the differences and similarities in the food consumption culture of Romanian and Transylvanian youth? • How much did the Transylvanian gastronomy preserve its Hungarian nature and how much could the Romanian eating traditions integrate into it? • Should the Transylvanian-Hungarians be treated as a separate consumer segment or is it sufficient if we categorize them as Romanian consumers? The home and outdoor eating habits of adolescents, the factors affecting their food consumption, their favourite food brands and their attitudes to healthy eating were presented.

description: We establish an asymptotic formula for $Ψ(x,y)$ whose shape is $x ρ(\log x/\log y)$ times correction factors. These factors take into account the contributions of zeta zeros and prime powers and the formula can be regarded as an (approximate) explicit formula for $Ψ(x,y)$. With this formula at hand we prove oscillation results for $Ψ(x,y)$, which resolve a question of Hildebrand on the range of validity of $Ψ(x,y) \asymp xρ(\log x/\log y)$. We also address a question of Pomerance on the range of validity of $Ψ(x,y) \ge x ρ(\log x/\log y)$.
 Along the way we improve classical estimates for $Ψ(x,y)$ and, on the Riemann Hypothesis, uncover an unexpected phase transition of $Ψ(x,y)$ at $y=(\log x)^{3/2+o(1)}$.

description: In this work we consider a wide variety of alternatives opened when applying the continuous spontaneous localization (CSL) dynamical collapse theory to the inflationary era. The definitive resolution of many of the issues discussed here will have to await, not only for a general relativistic CSL theory, but for a fully workable theory of quantum gravity. Our concern here is to explore these issues, and to warn against premature conclusions. This exploration includes: two different approaches to deal with quantum field theory and gravitation, the identification of the collapse-generating operator and the general nature and values of the parameters of the CSL theory. All the choices connected with these issues have the potential to dramatically alter the conclusions one can draw. We also argue that the incompatibilities found in a recent paper, between the CSL parameter values and the CMB observational data, are associated with specific choices made for the extrapolation to the cosmological context of the CSL theory (as it is known to work in non-relativistic laboratory situations) which do not represent the most natural ones.

This research being a pioneering work in Hungary analyses the impact of disasters and successive reconstruction and restoration activities on rural development. This present paper intends to provide preliminary results of the work already carried out in the Bereg Region. The sample area was selected due to the floods of 2001 and the following reconstruction both being exemplary ’phenomena’. Moreover, the extent of changes induced by such investments has become well-observable in the past 10-year-long period. The research aimed at revealing the impacts reconstruction, restoration and damage prevention had on the environmental, social and economic segments of this disaster-hit area. This paper focuses on the results and conclusions drawn from the analysis of social consequences resultant from the floods.

A korábbi szekunder adatokon elvégzett trendszámítások eredménye és a tényadatok igazolják a biodízel és a bioetanol felhasználás növekedését, amiben a jogszabályi háttér kialakításának és az adókedvezmény alkalmazásának jelentős szerepe van az EU tagállamaiban. Az elvégzett számítások igazolják, hogy a bioüzemanyag felhasználás mértéke a jelenlegi jogszabályi és gazdasági környezett átalakítása nélkül nem fog számottevően növekedni Magyarországon. Az ágazat szereplői között folytatott mélyinterjús megkérdezés és modellszámítás segítségével feltártuk azon változtatandó tényezőket, melyek alapján növelhető lenne Magyarország bioüzemanyag felhasználása, ezzel összefüggésben csökkenthető lenne a környezetszennyezés, valamint kismértékben, de növekedhetne a foglalkoztatottság is.

Results of the earlier trend’s calculations based on secondary data and the effective data prove the increase of use of biodiesel and bioethanol. Development of the legal background and adoption of the tax allowances in the EU member states play a significant role in this increase. Calculations, which have been done prove, that the rate of use of biofuels in Hungary will not significantly increase without the modification of the present legal and business environment. Based on deep interviews with stakeholders of this sector of economy, and on a modelling calculation we revealed the factors to be changed, upon which the use of biofuels in Hungary could be increased, and in this context the rate of employment could increase, and the pollution of environment decrease. The Results of our study however raise the questions: whether the present Hungarian agricultural potential how can be considered as a tool for it.

description: In emergencies, social coordination is especially challenging. People connected with each other may respond better or worse to an uncertain danger than isolated individuals. We performed experiments involving a novel scenario simulating an unpredictable situation faced by a group in which 2480 subjects in 108 groups had to both communicate information and decide whether to ‘evacuate'. We manipulated the permissible sorts of interpersonal communication and varied group topology and size. Compared to groups of isolated individuals, we find that social networks suppress necessary evacuations because of the spontaneous and diffuse emergence of false reassurance; yet, social networks also restrain unnecessary evacuations in situations without disasters. At the individual level, subjects have thresholds for responding to social information that are sensitive to the negativity, but not the actual accuracy, of the signals being transmitted. Social networks can function poorly as pathways for inconvenient truths that people would rather ignore.

description: A biztonság a turizmus egyik alapvető problémájává vált. A 2001 óta tartó időszakban a korábban ritkán jelentkező terrorcselekmények számának gyakoribbá válásával a turizmus szektorban új helyzet formálódott. Magyarországon a 2007-2013-as időszakban a turizmus erőteljes továbbfejlesztését irányozták elő, ugyanez történt az ország egyik jelentős nagyvárosában, Kecskeméten. A tanulmány az általános turizmus-biztonság kapcsolatok mellett a város válaszát is bemutatja a felmerült új problémákra. ----------------------------------------------------------------- Safety has become one of the fundamental problems of tourism. During the period elapsed since 2001, by having the occurrence of previously occasional terror actions increased, a new situation has been shaping in the tourism sector. For Hungary, an intensive improvement of tourism was envisaged for the 2007-2013 period just as in one of the country’s important towns, in Kecskemét. This paper intends to give a review on, in addition to the general tourism-safety intercourses, the response given by the town to the emerging new challenges.

description: In the last several years, tightly coupled PC clusters have become widely applied, cost effective resources for lattice gauge computations. This paper discusses the practice of building such clusters, in particular balanced design requirements. I review and quantify the improvements over time of key performance parameters and overall price to performance ratio. Applying these trends and technology forecasts given by computer equipment manufacturers, I predict the range of price to performance for lattice codes expected in the next several years.

description: In polyandrous species, sexual selection extends beyond mating competition to selection for egg fertilization. As a result, the degree to which factors influencing mating success impact overall reproductive success becomes variable. Here, we used a longitudinal behavioural and genetic dataset for a population of eastern water dragons (Intellagama lesueurii) to investigate the degree to which male dominance, a pre-mating selection trait, influences overall reproductive success, measured as the number of surviving offspring. Moreover, we examine the interactive effects with a genetic trait, individual inbreeding, known to influence the reproductive success of males in this species. We found fitness benefits of male dominance, measured as body size and frequency of dominance behaviours displayed. However, individuals' propensity to display dominance behaviours had mixed effects, depending on the degree of inbreeding. While inbred males benefited from frequent displays, highly outbred males exhibited better reproductive outputs when displaying to a lesser extent. Given that outbred males have enhanced reproductive success in this species, the costs of displaying dominance behaviours may outweigh the benefits. Overall, our results demonstrate the fitness benefits of dominance in a polyandrous lizard, and suggest that these are modulated by an independent genetic trait. Our results may contribute to explaining the presence of alternative mating tactics in this species, due to the variability in net fitness benefits of dominance. Our findings also reveal the challenges associated with investigating fitness traits in isolation, which may undermine the validity of results when important interactions are ignored.

description: Modern smart TVs often communicate with their remote controls (including those smart phone simulated ones) using multiple wireless channels (e.g., Infrared, Bluetooth, and Wi-Fi). However, this multi-channel remote control communication introduces a new attack surface. An inherent security flaw is that remote controls of most smart TVs are designed to work in a benign environment rather than an adversarial one, and thus wireless communications between a smart TV and its remote controls are not strongly protected. Attackers could leverage such flaw to abuse the remote control communication and compromise smart TV systems. In this paper, we propose EvilScreen, a novel attack that exploits ill-protected remote control communications to access protected resources of a smart TV or even control the screen. EvilScreen exploits a multi-channel remote control mimicry vulnerability present in today smart TVs. Unlike other attacks, which compromise the TV system by exploiting code vulnerabilities or malicious third-party apps, EvilScreen directly reuses commands of different remote controls, combines them together to circumvent deployed authentication and isolation policies, and finally accesses or controls TV resources remotely. We evaluated eight mainstream smart TVs and found that they are all vulnerable to EvilScreen attacks, including a Samsung product adopting the ISO/IEC security specification.

description: We present high resolution (~0.1"), very high Strehl ratio (0.97+-0.03) mid-infrared (IR) adaptive optics (AO) images of the AGB star RV Boo utilizing the MMT adaptive secondary AO system. RV Boo was observed at a number of wavelengths over two epochs (9.8 um in May 2003, 8.8, 9.8 and 11.7 um in February 2004) and appeared slightly extended at all wavelengths. While the extension is very slight at 8.8 and 11.7 um data, the extension is somewhat more pronounced at 9.8 um. With such high Strehls we can achieve super-resolutions of 0.1" by deconvolving RV Boo with a point-spread function (PSF) derived from an unresolved star. We tentatively resolve RV Boo into a 0.16" FWHM extension at a position angle of 120 degrees. At a distance of 390(+250)(-100) pc, this corresponds to a FWHM of 60(+40)(-15) AU. We measure a total flux at 9.8 um of 145+-24 Jy for the disk and star. Based on a dust thermal emission model for the observed IR spectral energy distribution and the 9.8 um AO image, we derive a disk dust mass of 1.6x10^-6 Msun and an inclination of 30 to 45 degrees from edge-on. We discuss whether the dust disk observed around RV Boo is an example of the early stages in the formation of asymmetric structure in planetary nebula.

Molecular phylogeny of the oxymonads
Creators: name: Heiss, Aaron Andrew
Publisher: name: University of British Columbia

description: The oxymonads are a group of structurally complex anaerobic flagellates about which we know very little. They are found in association with complex microbial communities in the guts of animals. There are five recognized families of oxymonads; molecular data have been acquired for four of these. Here, I describe the first molecular data from the last remaining group, represented by Saccinobaculus, an organism that is found exclusively in the hindgut of the wood-eating cockroach Cryptocercus. I sequenced small subunit ribosomal RNA (SSU rRNA) from total gut DNA to describe Saccinobaculus SSU rRNA diversity. I also sequenced SSU rRNA from manually isolated cells of the two most abundant and readily identifiable species: the type species S. ambloaxostylus and the taxonomically contentious S. doroaxostylus. I inferred phylogenetic trees including all five known oxymonad subgroups in order to elucidate the internal phylogeny of this poorly-studied group, to resolve some outstanding issues of the taxonomy and identification of certain Saccinobaculus species, and to investigate the evolution of character states within it. My analysis recovered strong support for the existence of the five subgroups of oxymonads, and consistently grouped the subgroups containing Monocercomonoides and Streblomastix, but was unable to resolve any further higher-order branching patterns. Additionally, I sequenced alpha-tubulin from S. ambloaxostylus, which in conjunction with environmentally obtained tubulin sequences established the use of an alternate genetic code by organisms related to Monocercomonoides and not by Saccinobaculus. This same alternate code is also used by Streblomastix, further cementing the relationship between that organism and the group including Monocercomonoides.

description: The effective Lagrangian including one loop corrections is deduced for the couplings of the charged Higgs with quarks and leptons, and with charginos and neutralinos. The effect of the one loop corrections is found to be quite significant in a number of sectors. The effective Lagrangian is then used to analyze the decay of the charged Higgs into a number of decay channels. Specifically we consider the decay of $H^+(H^-)$ into the decay modes $t\bar b$ ($\bar t b$), $\barτν_τ$ ($τ\bar ν_τ$), and $χ_i^+χ_j^0(χ_i^-χ_j^0)$ (i=1,2; j=1-4). The loop corrections to these decay modes are also found to be quite significant lying in the range 20-30% in significant regions of the parameter space of the SUGRA model. The effects of CP phases on the effective Lagrangian and on the branching ratios are also analysed and these effects found to be important.

description: The work presents results of a study conducted in 2009 and involving farmers who owned farms of up to 10 hectare located in 2 communes (gminas). The first commune is typically rural (in the Lubelskie Voivodeship) and the other is a multi-function commune. The farmers interviewed in both gminas, more than 50 years old owners of farms smaller than 5 hectare, are not going to make investment decisions or increase the size of their farms. The respondents who do intend to increase the size of their holding think that the optimum size of a farm, which brings sufficient income, ranges from 20 to 30 ha. They are younger farmers who own farms in a typically agricultural commune. Due to high land prices and lack of capital farmers prefer renting rather than buying land in order to increase their farms size. / Synopsis. Praca przedstawia wyniki badań przeprowadzonych w 2009 roku w gospodarstwach o powierzchni do 10 ha położonych w 2 gminach. Pierwsza z gmin jest gminą typowo rolniczą (woj. lubelskie), a druga należy do gmin wielofunkcyjnych. Ankietowani gospodarze w obydwu gminach, właściciele gospodarstw mniejszych niż 5 ha, w wieku powyżej 50 lat, nie zamierzają podejmować decyzji inwestycyjnych lub powiększać obszaru swoich gospodarstw. Respondenci, którzy wyrażają ochotę powiększenia wielkości gospodarstwa, uważają, że optymalna wielkość gospodarstwa, która przynosi zadowalający dochód, wynosi 20-30 ha. Są to młodsi gospodarze, którzy posiadają gospodarstwa w gminie typowo rolniczej. W związku z wysokimi cenami ziemi i brakiem kapitału, rolnicy preferują dzierżawę ziemi jako formę powiększania wielkości swojego gospodarstwa.
