Elhallgatás, beszéd, szubjektum Kemény Zsigmond regényeiben

A „posztmodern Petőfi” már polgárjogot nyert napjaink esszéisztikus irodalomtörténeti gondolkodásában. „Posztmodern” lenne Kemény Zsigmond is? Aligha, de a jelen befogadói tapasztalatai az életmű új közelítéseit teszik nyomatékossá

„Mégis új…”. A romantikus költészet modern retorikája Ady lírájában

Érdemes komolyan venni konferenciánk címének szövegköziségét, mely számomra azzal a kihívással jár, hogy – talán kissé váratlanul – megkíséreljek érdemben válaszolni a feltett kérdésre

Quantum backreaction effects in macroscopic systems

This thesis is concerned with two effects in macroscopic systems that are only revealed when taking into account the system’s quantum nature. For these effects to become strong, a high microstate degeneracy is essential, which motivates investigating their manifestation in de Sitter and black holes (BHs). The first part is concerned with the quantum description of phenomena of particle creation in a background. The common semiclassical treatment of such scenarios often allows for a nonperturbative method of analysis. We show that resolving the background as an N-particle state allows for a fully quantum perturbative analysis that produces the semiclassical nonperturbative results and allows to go beyond. In a model of two scalars as well as in scalar QED, we thus produce particle creation in time-dependent fields in terms of n -> 2 annihilation processes. Effects of backreaction in particular become dramatic within a single process in the case n ~ N, i.e., the near-classical system non-gradually transitions into a quantum state of a few highly energetic particles. We find that such “quantumization” is in general highly suppressed. By contrast, the reverse, “classicalizing” transitions, 2 -> N, may be unsuppressed because the degeneracy of the N-particle state can be sufficiently high in a consistent theory. For the case of N -> 2, such degeneracy is causing an enhancement only to the extent that the degenerate states are covered within an initial superposition. A BH described in terms of a bound state of N gravitons thus possesses a state unstable to single-process decay. We comment on the possibility of a near-classical BH generating the required level of superposition on relevant time scales. The second part is concerned with the so-called memory burden effect, which is universal to systems of high memory capacity and stops any gradual decay of the system. We study a prototype model to investigate whether the effect may be avoided by rewriting stored quantum information from one set of degrees of freedom to another one. We find that such rewriting-facilitated decay can proceed only very slowly compared to the initial stage of decay, s.t. the decay effectively remains suppressed. In both de Sitter and BHs, the effect manifests in a deviation from the semiclassical evolution of thermal particle emission and becomes strong the latest after a number of emissions on the order of the entropy. The stored quantum information responsible for the effect constitutes a quantum hair and may start to get released around the onset. If inflation ended not long before that time, the imprints of that primordial information can be observable. For BHs, in the absence of other strong effects of destabilizing kind, the effective stabilization after half-decay opens a new window for small primordial BHs as dark matter

Whole genome sequence analysis of a transmissible multidrug-resistance plasmid captured without cultivation from poultry litter

Use of antibiotics in the agricultural industry introduces selective pressure and, consequently, could increase the presence of antibiotic resistant organisms in surrounding environments. One such environment is litter (manure and bedding) produced during large-scale poultry production in the Shenandoah Valley. Litter, with its microorganisms, is commonly applied to fields within the Shenandoah River watershed. Antibiotic resistance (AR) and virulence genes are potentially transmissible between organisms through horizontal gene transfer of genetic mobile elements, for which poultry litter could be a reservoir. The typical, culture-based approach to detecting and analyzing AR plasmids and other mobile genetic elements is limited due to the inability to culture, isolate, and analyze all bacteria in nearly all environments. In addition, the expense and time of extracting and sequencing plasmids from culturable isolates is great. The goals of this study were (i) to use a non-culture-dependent plasmid isolation method to isolate AR plasmids directly from poultry litter, (ii) to sequence and assemble the whole genome of the plasmid capture strain E. coli LA61RifR, and (iii) use a combination of short- and long-read sequencing and computational methods to assemble and annotate one of the captured plasmids. It was also wished to determine the antibiotic susceptibility of the captured plasmids. An exogenous plasmid capture method was used to isolate tetracycline-resistance plasmids EH1-12, some of which conferred phenotypic resistance to a range of late-generation, clinically-significant antibiotics. Of the 12 transconjugants, 11 conferred resistance to more than one antibiotic (excluding tetracycline), the most common were resistances to piperacillin and piperacillin/tazobactam. Perhaps most striking was the resistance conferred by plasmid EH11 to aztreonam, a monobactam antibiotic effective against gram negative aerobic organisms, which has rarely been observed. Other surprising resistance phenotypes included ceftazidime and ciproflaxocin which are members of the cephalosporin and quinolone drug classes, respectively. The whole genomes of both the plasmid capture strain LA61RifR and one of the multidrug resistant transconjugants, LA61RifR::pEH11, were sequenced. SPAdes and Canu were used to assemble the genomes of LA61RifR and of LA61RifR::pEH11, respectively. Ninety-seven contigs assembled from short-read sequencing data comprised the LA61RifR genome and 5 contigs assembled from long-read data comprised the LA61RifR::pEH11 genome. One contig of LA61RifR::pEH11was identified as plasmid EH11. Genes encoding antibiotic resistance, bacteriocins, and aerobactin siderophore systems were annotated with ARGannot, RAST, and Prokka . Eight repeat regions, 47 transposase genes, and two regions responsible for plasmid replication and transfer were also identified. Overall this study, through phenotypic and genotypic analyses, demonstrated that poultry litter can act as reservoir for transmissible multidrug-resistant plasmids. Genome analysis also demonstrated the potential to transfer genes that contribute to a host’s virulence. Such resistances and virulence genes, encoded on transmissible plasmids, provide advantages to infectious agents and enable their survival in poultry litter and other environments, thus possibly complicating treatment of resulting infections

Model-Based Design for AUTOSAR Software Components

International audienceThe AUTOSAR initiative is without doubt one of the most forward-looking and important developments in the automotive industry. Tool support is essential for efficient software development according to AUTOSAR, particularly for developing the actual application software in the form of AUTOSAR software components. This paper deals with the adaptation of model-based design and automatic production code generation techniques to the proposed AUTOSAR workflow. It shows that existing approaches are well suited for the development of AUTOSAR software, preserving all the advantages of model-based design such as early testability, precise specifications, and last but not least, automatic production code generation

Modern Fair-Weather and Storm Sediment Transport Around Ship Island, Mississippi: Implications for Coastal Habitats and Restoration Efforts

The Mississippi – Alabama barrier island chain is experiencing accelerated sea level rise, decreased sediment supply, and frequent hurricane impacts. These three factors drive unprecedented rates of morphology change and ecosystem reduction. All islands in the chain have experienced land loss on the order of hectares per year since records began in the 1840s. In 1969, Hurricane Camille impacted as a Category 5, breaching Ship Island, and significantly reduced viable seagrass habitat. Hurricane Katrina impacted as a Category 3 in 2005, further widening Camille Cut. To better understand the sustainability of these important islands and the ecosystems they support, sediment transport dynamics must be quantified. In this study, four LiDAR datasets are used to investigate both subaerial and subaqueous volume changes during the most recent intense storm impact, Katrina, and the fair-weather period following. During the Katrina event, sediment comparable to 1.5 times the 2004 subaerial island volume was lost from the topo/bathy system. Only 1/5 of this volume was recovered between 2007 and 2010. The island returned to a net sediment loss between 2010 and 2012, although island area continued to increase. This highlights the importance of full topo/bathy datasets for morphodynamic analyses of barrier island systems. Seagrass patches around the island are primarily limited by exposure to wave energy, but are also limited by depth and rapid deposition events. Area and volume trends indicate seagrass habitat will not naturally increase, but a Camille Cut restoration may increase habitable area for seagrass if overwash processes are limited
