description: We make inroads into understanding the robustness of Variational Autoencoders (VAEs) to adversarial attacks and other input perturbations. While previous work has developed algorithmic approaches to attacking and defending VAEs, there remains a lack of formalization for what it means for a VAE to be robust. To address this, we develop a novel criterion for robustness in probabilistic models: $r$-robustness. We then use this to construct the first theoretical results for the robustness of VAEs, deriving margins in the input space for which we can provide guarantees about the resulting reconstruction. Informally, we are able to define a region within which any perturbation will produce a reconstruction that is similar to the original reconstruction. To support our analysis, we show that VAEs trained using disentangling methods not only score well under our robustness metrics, but that the reasons for this can be interpreted through our theoretical results.

description: Mission-critical and safety-critical applications generally tend to incorporate triple modular redundancy (TMR) to embed fault tolerance in their physical implementations. In a TMR realization, an original function block, which may be a circuit or a system, and two exact copies of the function block are used to successfully overcome any temporary fault or permanent failure of an arbitrary function block during the routine operation. The corresponding outputs of the function blocks are majority voted using 3-input majority voters whose outputs define the outputs of a TMR realization. Hence, a 3-input majority voter forms an important component of a TMR realization. Many synchronous majority voters and an asynchronous non-delay insensitive majority voter have been presented in the literature. Recently, quasi delay insensitive (QDI) asynchronous majority voters for TMR applications were also discussed in the literature. In this regard, this paper presents a new QDI asynchronous majority voter for TMR applications, which is better optimized in area compared to the existing QDI majority voters. The proposed QDI majority voter requires 30.2% less area compared to the best of the existing QDI majority voters, and this could be useful for resource-constrained fault tolerance applications. The example QDI TMR circuits were implemented using a 32/28nm complementary metal oxide semiconductor (CMOS) process. The delay insensitive dual rail code was used for data encoding, and 4-phase return-to-zero and return-to-one handshake protocols were used for data communication.

description: Статья посвящена анализу рассказа В.В.Набокова «Возвращение Чорба». По мнению автора, этот рассказ необычен тем, что Набоков прибегает к нарративным приемам и мотивам, хорошо известным по поздней прозе А.П.Чехова. Сопоставление с таким чеховским рассказом, как «Ионыч», позволяет расширить возможности интерпретации. Принято считать, что в рассказе Набокова духовно богатый мир главного героя противопоставлен мещанскому миру супругов Келлер, однако противостояние двух миров в рассказе слишком условно, не имеет фактического наполнения и потому обычно ошибочно трактуется с опорой на литературные клише. При всем том, что в «Возвращении Чорба» используются характерные для поэтики Чехова приемы (структура повествования, отсутствие назидательности, открытый финал, неспособность персонажей вести диалог), Набоков далек от идейно-нравственных исканий своего предшественника, смещая акценты в эстетическую плоскость.

description: The comparative historical method is a way of studying and explaining various phenomena, in which, based on the establishment of similarities between these phenomena in form, a conclusion is made about their genetic relationship, i.e. about their common origin. The peculiarity of the comparative historical method used in the study of cultural phenomena is that its starting point is the restoration and comparison of the most ancient elements common to various areas of material culture and knowledge.

description: The astrophysical S-factor of 14N(p,gamma)15O has been measured for effective center-of-mass energies between E_eff = 119 and 367 keV at the LUNA facility using TiN solid targets and Ge detectors. The data are in good agreement with previous and recent work at overlapping energies. R-matrix analysis reveals that due to the complex level structure of 15O the extrapolated S(0) value is model dependent and calls for additional experimental efforts to reduce the present uncertainty in S(0) to a level of a few percent as required by astrophysical calculations.

Sufficient conditions for local scaling laws for stationary martingale solutions to the 3D Navier-Stokes equations

Year: 2020
Subjects: subject: Analysis of PDEs (math.AP)

description: The main goal of this paper is to obtain sufficient conditions that allow us to rigorously derive local versions of the 4/5 and 4/3 laws of hydrodynamic turbulence, by which we mean versions of these laws that hold in bounded domains. This is done in the context of stationary martingale solutions of the Navier-Stokes equations driven by an Ornstein-Uhlenbeck process. Specifically, we show that under an assumption of \say{on average} precompactness in $L^3,$ the local structure functions are expressed up to first order in the length scale as nonlinear fluxes, in the vanishing viscosity limit and within an appropriate range of scales. If in addition one assumes local energy equality, this is equivalent to expressing the structure functions in terms of the local dissipation. Our precompactness assumption is also shown to produce stationary martingale solutions of the Euler equations with the same type of forcing in the vanishing viscosity limit.

description: We study a system of rods on the 2d square lattice, with hard-core exclusion. Each rod has a length between 2 and N. We show that, when N is sufficiently large, and for suitable fugacity, there are several distinct Gibbs states, with orientational long-range order. This is in sharp contrast with the case N=2 (the monomer-dimer model), for which Heilmann and Lieb proved absence of phase transition at any fugacity. This is the first example of a pure hard-core system with phases displaying orientational order, but not translational order; this is a fundamental characteristic feature of liquid crystals.

Tejelő tehenek legeltetésére a jó legelőkkel rendelkező, 20-30 tehenet tartó gazdaságok gondolhatnak. - Joining the European Union has opened up several new possibilities and challenges for farmers. One of these is grass farming and pasture feeding. Due to its low share and quality, the development of our grass farming is a very important task, because it doesn’t fulfil the role that it should. Farmers don’t realise the benefits of grassland-based feeding in the case of dairy cattle herds. Grazing is devoted only to young heifers. Nevertheless, nearly all of them have already joined various support programmes connected to grass farming or grassland usage. In their opinion the best solution would be Hungarian spotted cattle farming or beef cattle farming. Only the farmers with good pastures and 20-30 dairy cows can consider pasture feeding.

description: A szerzők vizsgálataikban a hazai juhtenyésztés jövedelmezőségének és ver-senyképességének javítása érdekében két biotechnikai eljárás – az ivarzás-indukálás és a mesterséges termékenyítés – gyakorlati alkalmazásával és ökonó-miai elemzésével foglalkoztak. Magyar merinó juhokat, továbbá lacaune és lacaune keresztezett jerkéket próbáltak vemhesíteni szezonon kívül, május végén, ivarzás-indukálás után. Így az állatokat a szokásos vemhesítési periódus előtt, négy hónappal korábban vették tenyésztésbe, megcélozva ezzel a magasabb vágóállat felvásárlási árakat. A kezelések költségét jelentős mértékben megha-ladta a bárányonként elérhető extraprofit, amit a decemberi – keresleti piacra történő – bárányértékesítéskor értek el, ráadásul a laktációs idő és a kifejt tej mennyiségének növelésével további bevételre tettek szert a lacaune állománynál. Azok a tenyésztők, akik megfelelő tartási és takarmányozási körülményekkel rendelkeznek, eredményesen próbálkozhatnak a különböző biotechnikai eljárások alkalmazásával, ezzel lehetőség nyílik a juhtenyésztés jövedelmezőségének fokozására. - During their investigations the authors dealt with the practical applications and economic analysis of two biotechnical methods - oestrus induction and artificial insemination – in the interests of improving domestic lambing’s profitability and competitiveness. Two groups of animals of different species were examined. Attempts were made out of season, at the end of May, to impregnate Hungarian merino lambs in the first group, and Lacaune and Lacaune-crossed ewe lambs in the second group, following oestrus induction. In this manner, animals were taken into breeding four months before the usual breeding season, targeting the higher buying-up price for slaughter-lambs. The cost of treatment was significantly lower than the extra profit achieved in the market in December. Furthermore, the longer lactation period and increased quantity of milk resulted in additional income from the Lacaune stock. These investigations proved that breeders with suitable maintenance and feeding conditions can try different biotechnical methods with success. With the help of biotechnical methods the profitability of sheep breeding can be raised. These methods are already available for breeders.

description: We apply a theoretical approach, originally introduced to describe aeolian ripples formation in sandy deserts, to the study of surface instability in ion sputtered surfaces. The two phenomena are distinct by several orders of magnitudes and by several physical mechanisms, but they obey to similar geometrical constraints and therefore they can be described by means of the same approach. This opens a novel conceptual framework for the study of the dynamical surface roughening and ripple formation on crystal and amorphous surfaces during ion sputtering.

description: Dalam dua dekade terakhir, praktik kolektif dalam penciptaan seni telah menjadi kecenderungan yang semakin berkembang, tidak hanya dalam produksi karya seni, tetapi juga dalam praktik kuratorial. Kolektif seniman menjadi aktor utama dalam menjalankan seni secara kolektif. ruangrupa (selalu ditulis dengan huruf kecil dan tanpa spasi) merupakan kolektif seniman yang didirikan pada tahun 2000 di Jakarta. ruangrupa ditunjuk sebagai kurator untuk edisi ke-15 Documenta (selanjutnya disebut documenta fifteen), sebuah pameran seni kontemporer internasional berformat biennale yang diselenggarakan setiap lima tahun sekali. Dalam documenta fifteen, ruangrupa memperkenalkan konsep “lumbung” sebagai mekanisme pengelolaan dan berbagi sumber daya bersama.

Penelitian ini berfokus pada praktik kuratorial kolektif yang dijalankan oleh ruangrupa dalam documenta fifteen, dengan dua aspek utama: pertama, bagaimana praktik kuratorial kolektif ruangrupa dikembangkan melalui mekanisme lumbung; kedua, bagaimana resepsi kritis terhadap praktik kuratorial kolektif ruangrupa dalam documenta fifteen. Penelitian ini bertujuan untuk memberikan pemahaman baru dalam wacana studi kuratorial. Pendekatan yang digunakan dalam penelitian ini adalah metode deskriptif-kualitatif, dengan teori utama Curatorial Studies dan Art Collective. Selain itu, penelitian ini juga menyoroti aspek Critical Reception untuk memahami bagaimana publik merespons praktik kuratorial dalam documenta fifteen.

Penelitian ini menyimpulkan bahwa praktik kuratorial yang diterapkan oleh ruangrupa telah mendesentralisasikan peran kurator. Berdasarkan analisis terhadap respon kritis, struktur kuratorial yang terdesentralisasi menghadapi sejumlah tantangan dan kendala dalam proses penerapannya. Desentralisasi agensi kurator bukanlah hal baru dalam sejarah Documenta, karena beberapa edisi sebelumnya telah menerapkan struktur Collective Curating, di mana sekelompok kurator bekerja sebagai tim. Namun, dalam documenta fifteen, ruangrupa beroperasi sebagai kolektif seniman dengan nilai-nilai kolektif yang telah mereka praktikkan sejak lama. Oleh karena itu, praktik kuratorial kolektif oleh kolektif seniman dapat dipandang sebagai fenomena baru dalam sistem operasional Documenta dan sebagai gejala baru dalam studi kuratorial.

description: A gyümölcsök fogyasztása 1993 és 1997 között fokozatosan visszaesett 65 kg-ról 49 kg-ra, majd emelkedésnek indult. Ez a folyamat egészen 2003-ig tartott, amikor 72 kg volt a fejenkénti fogyasztás. A termékek közül legtöbbet almából fogyasztunk, átlagosan 15 kg-ot fejenként, ennek a mennyiségnek valamivel több mint fele fogy el déligyümölcsökből és ettől is kevesebb görögdinnyéből, a többi gyümölcs jóval ezen értékek alatt található. A különböző szegmensek fogyasztási ingadozásai alapján elmondható, hogy a magasabb jövedelműek fogyasztása mindig stabilabb (a fogyasztás átlagához viszonyítva, százalékban kifejezve). Abszolút mércével viszont (az átlagtól való, kg-ban mért eltérés alapján) a magasabb jövedelműek fogyasztása nagyobb mértékben ingadozik, és így a teljes fogyasztást is nagyobb mértékben befolyásolják. A gyümölcsöket a piac differenciáltsága és a fogyasztás ingadozása alapján két csoportba osztottuk. Az 1. csoportba az ingadozó fogyasztású és differenciált piacú gyümölcsök tartoznak. A 2. csoportba pedig azok a termékek kerültek, amelyek fogyasztása kevésbé változik és a piacuk is kevésbé differenciált. - The aim of this work is to describe changes in fruit consumption in different income levels. Our hypothesis is that in higher income levels the fluctuation of consumption is higher (in absolute values), but relatively it is lower (according to average consumption at a given income level). While consumers with higher incomes have a stronger influence on consumption as a whole (than those with lower incomes), their relative indicator is much more stabilised. This is demonstrated in the case of processed fruits: consumers with the highest income increased their consumption to the highest degree (in absolute values); yet according to their average consumption (relative value) their increase was the lowest. This principle can be found in the case of other fruits as well. Apples, watermelon and tropical fruits are emphasised in this research. As for the relationship between segments with the lowest and highest income, the gap between them has been decreasing since 1997. This fact is due to the consumption fluctuations of those with the highest income (in absolute values). After the research into the above-mentioned products, other important fruits are examined and categorised.

description: Supernova remnants (SNRs) are believed to be the source of Galactic cosmic rays (CRs). SNR shocks accelerate CR protons and electrons which reveal key insights into the non-thermal physics by means of their synchrotron and $γ$-ray emission. The remnant SN 1006 is an ideal particle acceleration laboratory because it is observed across all electromagnetic wavelengths from radio to $γ$-rays. We perform three-dimensional (3D) magnetohydrodynamics (MHD) simulations where we include CR protons and follow the CR electron spectrum. By matching the observed morphology and non-thermal spectrum of SN 1006 in radio, X-rays and $γ$-rays, we gain new insight into CR electron acceleration and magnetic field amplification. 1. We show that a mixed leptonic-hadronic model is responsible for the $γ$-ray radiation: while leptonic inverse-Compton emission and hadronic pion-decay emission contribute equally at GeV energies observed by Fermi, TeV energies observed by imaging air Cherenkov telescopes are hadronically dominated. 2. We show that quasi-parallel acceleration (i.e., when the shock propagates at a narrow angle to the upstream magnetic field) is preferred for CR electrons and that the electron acceleration efficiency of radio-emitting GeV electrons at quasi-perpendicular shocks is suppressed at least by a factor ten. This precludes extrapolation of current one-dimensional plasma particle-in-cell simulations of shock acceleration to realistic SNR conditions. 3. To match the radial emission profiles and the $γ$-ray spectrum, we require a volume-filling, turbulently amplified magnetic field and that the Bell-amplified magnetic field is damped in the immediate post-shock region. Our work connects micro-scale plasma physics simulations to the scale of SNRs.

A genetic and molecular analysis of histone deacetylase one in Drosophila melanogaster : specific missense mutations suppress position effect variegation
Creators: name: Mottus, Randall C.
Publisher: name: University of British Columbia
Year: 2009

description: Essentially all higher organisms are made up of two or more types of tissues. The specific identity of those tissues is dependent on the genes that are expressed within the cells of the particular tissue type. The correct set of genes must be expressed and genes, that are not part of the set specific to that tissue, must be kept silenced. In addition, in most cells, the decision whether a gene will be active or not is made early in development and therefore must be passed on to daughter cells. The focus of this thesis is an investigation into the mechanism or mechanisms employed by eukaryotes to silence genes and to maintain that silenced state throughout development. The model system our laboratory has been using to investigate silencing is position effect variegation (PEV) in D. melanogaster. In PEV a gene is silenced in a certain proportion of the cells of a tissue in which it is normally expressed due to its proximity to an heterochromatic breakpoint. The decision whether a gene will be active or inactive is made early in development and that decision is passed on to daughter cells with reasonable fidelity. Thus PEV mimics normal development in many ways. This has led our lab, and several others, to try to dissect the mechanisms underlying PEV with the hope they will shed some light on the more general silencing mechanisms that occur during normal development. In Chapter 2 of this thesis I describe the cloning and characterization of a gene identified in a screen for dominant suppressors of the variegation associated with PEV [Su(var)s]. The gene encodes HDAC1 , an histone deacetylase homologous to HDAC1 from mammals and Rpd3 from S. cerevisiae. Specific mis-sense mutations in HDAC1 cause strong dominant suppression of PEV while null or hypomorphic mutations have no effect on the variegating phenotype. I present a model proposing that the mis-sense mutations are acting as anti-morphic mutations that "poison" the deacetylase complex. The level of variegation of a gene subject to PEV is very sensitive to a wide variety of factors, some, which may be acting directly and some, which may be acting indirectly. HDAC1 localizes to a large number of sites on the polytene chromosomes of D. melanogaster (Pile and Wasserman, 2000) and therefore appears to regulate a large number of genes. Thus it is a possibility that the Su(var) mutations in HDAC1 are affecting PEV indirectly. In Chapter 3 I present data from chromatin immuno-precipitation experiments (X-ChIP) that provides compelling evidence that HDAC1 is acting directly on the euchromatic region subject to silencing in PEV. I propose a model linking the histone deacetylase activity of HDAC1 to the function of other proteins known to be involved in the silencing associated with PEV.

description: We present the first near-infrared (K'-band) homogeneous observations of a complete sub-sample of the 3CR radio catalogue comprising all High Excitation Galaxies (HEGs) at z<0.3. After showing that the surface brightness decomposition technique to measure central point-like sources is affected by significant uncertainties for the objects in the studied sample, we present a new, more accurate method based on the R-K' color profile. Via this method we find a substantial nuclear K'-band excess in all but two HEGs -- most likely directly associated to their nuclear emission -- and we measure the corresponding 2.12 $μ$m nuclear luminosities. Within the frame of the unification scheme for radio-loud active galactic nuclei, it appears that obscuration alone is not able to account for the different nuclear properties of the majority of the HEGs and Broad Line Radio Galaxies (BLRGs), and also scattering of the (optically) hidden nuclear light from a compact region must be invoked. More precisely, for ~70% of the HEGs the observed point-like optical emission is dominated by the scattered component, while in the K'-band both scattered and direct light passing through the torus contribute to the observed nuclear luminosity. The estimated fraction of scattered light ranges from a few tenths to a few percent, while the torus extinction is between 15

description: Az elemzés szerint a Somogy megyei vadásztársaságok nyereségesek voltak. Az összköltség szignifikánsan (p<0,05) befolyásolta a bevételek nagyságát. A vizsgált időtartam alatt a legnagyobb bevételi forrás (értékben, arányban) a kül-földi bérvadásztatásból, a legjelentősebb kiadás a vadgazdálkodási költségből származott. A 2004. évben a nagymértékű kiadásnövekedést a Somogy megyei vadásztársaságok kompenzálták, de az eltérő adottságok és lehetőségek miatt, a felmerült problémát a társaságok különböző módon oldották meg (pl. tagdíj nö-velésével, a vaddisznóhajtás értékesítésével, tárgyi eszközök értékesítésével, a vadgazdálkodási költség csökkentése segítségével). A kutatás kvalitatív részéből (a mélyinterjúkból) kiderült, hogy a vadásztársaságok anyagi tartalékai (pl. a pénztartalék, az eszközállomány) a 2005. év végére jelentősen lecsökkentek, és szinte minden esetben felmerült az a kérdés, hogy a jövőben milyen forrásból, il-letve miként finanszírozzák a folyamatosan növekedő költségeket? - The economic and social conditions of agricultural production have greatly changed since the process of acceding to the EU. The changes occurring in externals have a deep impact on the operation of game management companies, which influences the costs and revenues at micro level. Therefore, the aim of the study was to investigate the costs and revenues of hunting companies in Somogy County, during the years from 2003 to 2005, and to carry out statistical analyses and reveal the reasons and causes. The results show that the total revenue is higher than the total cost in the three years, thus on average, the game management companies are profitable, and the total costs have significant (p<0.05) impact on the revenues. During the period analysed, the highest revenue (both in value and proportion) came from foreign guest-shooting, while the highest costs were represented by game management costs. Although the hunting companies in Somogy County were able to compensate for the huge increase in expenses seen in 2004, due to their different potentials and conditions the companies solved that problem in different ways (such as increasing membership fees, wild boar beating, sale of assets, or a decrease in game management costs). According to the qualitative survey carried out with in-depth interviews, the material reserves (cash, assets) of the hunting companies fell by the end of 2005. In almost all cases the question arose, from what sources can the companies finance the continuously increasing costs in the future?

description: Based on the classical SIR model, we derive a simple modification for the dynamics of epidemics with a known incubation period of infection. The model is described by a system of integro-differential equations. Parameters of our model directly related to epidemiological data. We derive some analytical results, as well as perform numerical simulations. We use the proposed model to analyze COVID-19 epidemic data in Armenia. We propose a strategy: organize a quarantine, and then conduct extensive testing of risk groups during the quarantine, evaluating the percentage of the population among risk groups and people with symptoms.

description: Axion-like particles (ALPs) are pseudo Nambu-Goldstone bosons associated with spontaneously broken global symmetries emerging in many extensions of the Standard Model. Assuming the most general effective Lagrangian up to dimension-5 operators for an ALP interacting with the SM fields, we investigate for the first time the sensitivity of the LHC13 to the ALP production in association with a di-jet. This study is focused on light ALPs which appear as invisible particles at the detector. Performing a realistic detector simulation and deploying a multivariate technique to best discriminate the signal from backgrounds, we set expected upper bounds on the ALP coupling to gluons. A comprehensive set of background processes is considered, and it is shown that this process provides significant sensitivity to the ALP-gluon coupling and the resulting bound is more stringent than those already obtained at the LHC. We also present prospects for the HE-LHC27 and FCC-hh100 and show that these future colliders are able to improve the limits from the LHC by roughly one order of magnitude.

description: A canonical quantization scheme for localized surface plasmons (LSPs) in a metal nanosphere is presented based on a microscopic model composed of electromagnetic fields, oscillators that describe plasmons, and a reservoir that describes excitations other than plasmons. The eigenmodes of this fully quantum electrodynamic theory show a spectrum that includes radiative depolarization and broadening, including redshifting from the quasi-static LSP modes, with increasing particle size. These spectral profiles correctly match those obtained with exact classical electrodynamics (Mie theory). The present scheme provides the electric fields per plasmon in both near- and far-field regions whereby its utility in the fields of quantum plasmonics and nano-optics is demonstrated.

Complexity in Strongly Correlated Electronic Systems

description: A wide variety of experimental results and theoretical investigations in recent years have convincingly demonstrated that several transition metal oxides and other materials, have dominant states that are not spatially homogeneous. This occurs in cases in which several physical interactions -- spin, charge, lattice, and/or orbital -- are simultaneously active. This phenomenon causes interesting effects, such as colossal magnetoresistance, and it also appears crucial to understand the high temperature superconductors. The spontaneous emergence of electronic nanometer-scale structures in transition metal oxides, and the existence of many competing states, are properties often associated with complex matter where nonlinearities dominate, such as soft materials and biological systems. This electronic complexity could have potential consequences for applications of correlated electronic materials, because not only charge (semiconducting electronic), or charge and spin (spintronics) are of relevance, but in addition the lattice and orbital degrees of freedom are active, leading to giant responses to small perturbations. Moreover, several metallic and insulating phases compete, increasing the potential for novel behavior.

description: In Thouless pump, the charge transport in a one-dimensional insulator over an adiabatic cycle is topologically quantized. For nonequilibrium initial states, however, interband coherence will induce a previously unknown contribution to Thouless pumping. Though not geometric in nature, this contribution is independent of the time scale of the pumping protocol. In this work, we perform a detailed analysis of our previous finding [Phys. Rev. B 91, 085420 (2015)] in an already available cold-atom setup. We show that initial states with interband coherence can be obtained via a quench of the system's Hamiltonian. Adiabatic pumping in the post-quench system are then examined both theoretically and numerically, in which the interband coherence is shown to play an important role and can hence be observed experimentally. By choosing adiabatic protocols with different switching-on speeds, we also show that the contribution of interband coherence to adiabatic pumping can be tuned. It is further proposed that the interband coherence induced correction to Thouless pumping may be useful in capturing a topological phase transition point. All our results have direct experimental interests.

Influence of ultraviolet-B radiation on crop-weed competitive interactions

description: A greenhouse study showed that ultraviolet-B (UV-B; 290-315 nm) radiation effects on seedling growth and morphology differed widely among agricultural weeds, vegetable crops, and broccoli cultivars. Relative UV-B-sensitivity of plants within these groups also differed. These differential responses to UV-B radiation may alter competition among associated species for limited resources. Broccoli (Brassica oleracea L. var. italica cv. Purple Sprouting) and lamb's-quarters (Chenopodium album L.) were chosen for competition experiments based on their growth and morphological sensitivity to UV - B radiation. Greenhouse competition experiments were conducted in 1999 (summer) and 2000 (fall) at ambient (4 kJ m⁻²D⁻¹) and above-ambient (7 kJ m⁻²D⁻¹) biologically effective UV - B (UV-BBE) radiation levels. Broccoli and lamb's-quarters were grown in monocultures (144, 256, and 400 plants m⁻²) and all binary mixtures in a randomized block design with four replications. Yield per plant declined with increasing species densities; UV - B - effects and treatment interactions were often significant. Inverse yield-density relationships using biomass indicated that in both years broccoli gained in competitiveness relative to lamb's-quarters at above-ambient UV - B radiation. UV - B effects were greater on inter- compared with intraspecific competition. Growth indices (specific leaf weight, leaf weight ratio, leaf area ratio, leaf area index, and shootroot ratio) indicated that morphology and biomass partitioning were influenced by experimental treatments. Total biomass growth was proportional to growth of biomass components and leaf area. Plant densities had greater influence compared with UV-B-effects on allometric adjustments. Direct UV - B radiation and species densities effects were more often detected in broccoli compared with lamb's-quarters. Broccoli height and leaf greenness increased at aboveambient UV - B radiation, while those of lamb's-quarters declined. Over time, inverse yield-density relationships indicated that the contribution of broccoli to interception of photosynthetically active radiation (PAR) decreased at ambient and increased at above-ambient U V - B radiation. Inverse yield-density relationships using overhead canopy coverage showed that lamb's-quarters was always the stronger competitor. Broccoli however, gained in competitiveness relative to lamb'squarters at above-ambient UV - B radiation in both years. Overall, this study indicated that architectural and physiological plasticity of broccoli and lamb's-quarters, in response to UV - B radiation, influenced ability of each species within this association to compete for PAR.

description: The paper intends to draw some topics about relationship between word and image in works and thinking of Aby Warburg and Walter Benjamin. In recent history of ideas, word and image are frequently interpreted as alternative ways to express reality. In both, Warburg and Benjamin, and in spite of their very different methods of approaching history of art and history of culture, we can find a similar idea of the connection between word and image. The two authors deem that this relationship is necessary to understand historical facts and legacy.

description: A bizalom és a közös akciókhoz való hozzájárulás közötti pozitív kapcsolat az egyén önmagára vonatkozó megítélésében a kutatásban igazolódott. A bizalmi szintet jónak ítélők egyértelműen hajlandóak az időbeli áldozatvállalásra, azonban a megfelelő szintű bizalom a pénzügyi hozzájárulásban már nem elegendő, itt már hiányzik a pozitív irányú kapcsolat. A bizalmi szint és mások időbeli és pénzbeli hozzájárulási hajlandósága közötti kapcsolat nem egyértelmű. A bizalmi szint növekedéséből nem következik automatikusan, hogy a gazdasági szereplők mások hozzájárulási hajlandóságát pozitívabbnak ítélnék. Az ágazati szereplők szervezettségi szintje és az érdekérvényesítés gyakoriságának vizsgálatakor nem állítható, hogy az ágazatot szervezettebbnek vélők pozitívabbnak ítélnék az érdekérvényesítést is. A szervezettségi szint és a bizalom közötti kapcsolat vizsgálatánál bebizonyosodott, hogy a kapcsolat nem szignifikáns, vagyis a magasabb szervezettségi szintből sem következik egyértelműen, hogy az ágazat szereplői jobban bíznának egymásban. - Research has shown that trust and contribution to common action is positively related to an individual’s self-assessment. People who favourably judge the level of trust are willing to make sacrifices of their time. However, an adequate level of trust is not sufficient for money contributions because in this case the above positive relationship is absent. The relationship between the level of trust and others’ willingness to contribute time and money is not unambiguous. An increase in trust level does not automatically follow a positive increase in judging the willingness of other economic partners to contribute. From studies involving organisation levels and frequency of defending common interest it has been shown that people who are better organised do not necessarily judge more positively the efficiency with which their interests are defended. When investigation the relationship between organisational level and trust we have shown that this relationship is not significant, that is just because people are better organised, it does not unambiguously follow that they necessarily trust each other more.
