I COLEOTTERI TENEBRIONIDI DI ROMA (Coleoptera, Tenebrionidae)
Creators: name: Fattorini, Simone
Publisher: name: Fragmenta Entomologica
Year: 2013

description: In base alla revisione dei dati di letteratura e all’esame di circa 2000 esemplari raccolti a Roma dal 1880 ai nostri giorni, è stata accertata la presenza in questa città di 45 specie di Tenebrionidi, ovvero oltre il 26% delle specie e sottospecie di Tenebrionidi note per l’Italia peninsulare. Altre 18 specie, di cui è stato esaminato materiale cartellinato “Roma” o citato di questa città, sono da considerarsi certamente o verosimilmente estranee. 11 specie citate da Gardini (1997) sono rimosse dalla fauna di Roma, mentre ne vengono segnalate per la prima volta altre 29. Di ogni specie sono indicati: i dati riguardanti il materiale esaminato, i dati di letteratura, la distribuzione, l’ecologia, la distribuzione ambientale nella città di Roma. In base all’estensione temporale delle ricerche, l’elenco fornito dovrebbe essere considerato pressoché completo. Specie rare sono B. gigas, B. lethifera, C. atropos, M. tibialis, G. obscurum, S. metallica, Corticues spp. e N. picipes. Per alcune di esse sono noti pochi reperti, prevalentemente di vecchia data. Alcune specie presenti a Roma mostrano una generale rarefazione, anche in ambienti naturali, probabilmente a causa di pressioni antropiche. Specie considerate un tempo comuni a Roma (come T. italica, A. bacarozzo, Gonocephalum spp., O. sabulosum o N. planippennis) sono oggi piuttosto rare o localizzate, mentre specie con una più ristretta tolleranza ecologica (come C. atropos, M. tibialis, S. metallica, P. violacea, Corticeus spp.) sono probabilmente divenute molto rare o si sono estinte a Roma. Le specie che hanno avuto maggior successo nella colonizzazione degli ambineti urbani sono elementi xerotermofili, o con ampia tolleranza ecologica, come A. luigionii, S. striatus, B. gibba e P. meridianus., specie tipiche di ambienti aperti ed aridi, comuni nei giardini, nei parchi, nei siti archeologici, nelle aree ruderali, ecc. La presenza nella città di queste specie, tuttora abbondanti, può essere seriamente compromessa dalle operazioni di pulizia delle aree verdi, dall’inquinamento e dalla espansione urbanistica.

description: We use multifractal detrended fluctuation analysis (MF-DFA), to See query 1 study sunspot number fluctuations. The result of the MF-DFA shows that there are three crossover timescales in the fluctuation function. We discuss how the existence of the crossover timescales is related to a sinusoidal trend. Using Fourier detrended fluctuation analysis, the sinusoidal trend is eliminated. The Hurst exponent of the time series without the sinusoidal trend is $0.12\pm 0.01$. Also we find that these fluctuations have multifractal nature. Comparing the MF-DFA results for the remaining data set to those for shuffled and surrogate series, we conclude that its multifractal nature is almost entirely due to long range correlations.

FIFTY (50) SENIOR MALE ATHLETES, FROM THREE DIFFERENT SPORTS; AMONG THEM, NINETEEN (19) KARATEKAS, THIRTEEN (13) HANDBALL PLAYERS, AND EIGHTEEN (18) CYCLISTS PARTICIPATED IN THIS STUDY. THESE ATHLETES UNDERWENT ANTHROPOMETRIC MEASUREMENTS AND A FORCE-VELOCITY TEST ON AN AXIOM STATIONARY ERGOMETER, WHICH INVOLVED TWO 6-SECOND ACCELERATIONS, INTERSPERSED WITH AT LEAST 5 MINUTES OF ACTIVE RECOVERY. THE PURPOSE OF THE TEST IS THE MEASUREMENT OF PEAK POWER USING A POWERTAP G3 HUB POWER METER. ALL STATISTICAL ANALYSES WERE PERFORMED USING SPSS VERSION 22.0 FOR WINDOWS. COMPARISONS BETWEEN THE HREE GROUPS OF ATHLETES WERE MADE USING ANALYSES OF VARIANCE (ANOVA). INTERGROUP OMPARISON WAS PERFORMED USING THE TUKEY POST HOC TEST.INTERGROUP ANALYSIS SHOWED THAT HANDBALL PLAYERS ARE HEAVIER AND TALLER THAN KARATEKAS AND CYCLISTS. THE MAXIMAL ANAEROBIC POWER IN THE ABSOLUTE VALUE OBTAINED BY THE HANDBALL PLAYERS WAS HIGHER THAN THAT FOUND IN THE KARATEKAS AND ALMOST SIMILAR TO THAT RECORDED BY THE HANDBALL PLAYERS.

description: A number of very careful econometric studies have been interpreted as showing that publicly funded research and development conducted by private firms has had little discernable impact on firm level profits or productivity. In contrast historical studies have shown that military and defense-related research development and procurement conducted by private firms has been an important source of technology development across a broad spectrum of U.S. manufacturing industries. Careful narrative analysis represents a more effective way of capturing the complementarities between military and defense-related research, development, and procurement on commercial technology development than econometric analysis.

description: $β$-NMR of isolated $^8$Li has been investigated in the normal state of 2H-NbSe$_2$. In a high magnetic field of 3T a single resonance is observed with a Gaussian line width of 3.5 kHz. The line shape varies weakly as function of magnetic field and temperature but has a strong orientation dependence. The nuclear electric quadrupole splitting is unresolved implying that the electric field gradients are 10-100 times smaller than in other non-cubic crystals. The nuclear spin relaxation rate is also anomalously small but varies linearly with temperature as expected for Korringa relaxation in a metal. These results suggest that Li adopts an interstitial position between the weakly coupled NbSe$_2$ layers and away from the conduction band.

description: Photon loss in optical fibers prevents long-distance distribution of quantum information on the ground. Quantum repeater is proposed to overcome this problem, but the communication distance is still limited so far because of the system complexity of the quantum repeater scheme. Alternative solutions include transportable quantum memory and quantum-memory-equipped satellites, where long-lived optical quantum memories are the key components to realize global quantum communication. However, the longest storage time of the optical memories demonstrated so far is approximately 1 minute. Here, by employing a zero-first-order-Zeeman magnetic field and dynamical decoupling to protect the spin coherence in a solid, we demonstrate coherent storage of light in an atomic frequency comb memory over 1 hour, leading to a promising future for large-scale quantum communication based on long-lived solid-state quantum memories.
Bayesian approach to superstatistics
Creators: name: Sattin, Fabio
Publisher: name: arXiv
Year: 2006
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The superstatistics approach recently introduced by Beck [C. Beck and E.G.D. Cohen, Physica A 322, 267 (2003)] is a formalism that aims to deal in a unifying way with a large variety of complex nonequilibrium systems, for which spatio-temporal fluctuations of one intensive variable (the "temperature" 1/b) are supposed to exist. The intuitive explanation provided by Beck for superstatistics is based on the ansatz that the system under consideration, during its evolution, travels within its phase space which is partitioned into cells. Within each cell, the system is described by ordinary Maxwell-Boltzmann statistical mechanics, i.e., its statistical distribution is the canonical one, but b varies from cell to cell, with its own probability density f(b). In this work we first address that the explicit inclusion of the density of states in this description is essential for its correctness. The correction is not relevant for developments of the theory, but points to the fact that its correct starting point, as well its meaning, must be found at a more basic level: the pure probability product rule involving the intensive variable b and its conjugate extensive one. The question therefore arises how to assign a meaning to these probabilities for each specific problem. We will see that it is easily answered through Bayesian analysis. This way, we are able to provide an interpretation for f(b), that was not fully elucidated till now.

ATLAS: The cotyles of a partial atlas, AMNH 8481, are round in shape and are separated by a short intercotyle process. The posterior cotyle is round and is incompletely filled in with bone. The ventral side of the vertebra is marked by a depression, which is deeper on the anterior side and bounded by two ridges that meet along the midline. The atlas of Opisthotriton can be distinguished from that of Prodesmodon by its larger size, rounded cotyles, and more prominent intercotylar process.
DORSAL VERTEBRAE: A dorsal vertebra of Opisthotriton kayi has been described in great detail by Estes (1964, pp. 82-83). TheJudith River Formation specimens are of the same size or slightly smaller than AMNH 8112 from the Lance Formation, but are otherwise morphologically indistinguishable.
DENTARY: Unfortunately, specimen AMNH 8485 is fragmentary and without teeth. The tooth bases indicate that the teeth are pleurodont and extend close to the lingual edge of the tooth-bearing border. The anterior part of Meckel's fossa has been broken and the divergence between the dorsal and ventral border of the fossa is not so great as in Habrosaurus.

Viene proposta la riabilitazione di Agrilus (Agrilus) italicus Obenberger, 1920 come sottospecie di Agrilus cyanescens (Ratzeburg, 1837) e della ssp. populneus Schaefer, 1946 di A. suvorovi Obenberger, 1920. A seguito della designazione del lectotipo di Agrilus (Agrilus) paganettii Obenberger, 1913, viene ridescritto A. paganettii sensu Curletti, 1980 con il nome di A. etruscus n. sp. E’ inoltre espressa l’opinione secondo cui le specie del genere Agrilus presenti in Italia siano da attribuire a soli quattro sottogeneri, e non a nove come proposto da Alexeev (1998).

description: We investigate the mass-velocity dispersion relation (MVDR) in 29 galaxy clusters in the HIghest X-ray FLUx Galaxy Cluster Sample (HIFLUGCS). We measure the spatially resolved, line-of-sight velocity dispersion profiles of these clusters, which we find to be mostly flat at large radii, reminiscent of the rotation curves of galaxies. We discover a tight empirical relation between the baryonic mass $M_\mathrm{bar}$ and the flat velocity dispersion $σ$ of the member galaxies, i.e. MVDR, $\log(M_\mathrm{bar}/M_\odot)=4.1^{+0.4}_{-0.4}\,\log(σ/\mathrm{km}\,\mathrm{s}^{-1})+1.6^{+1.0}_{-1.3}$, with the lognormal intrinsic scatter of $12^{+3}_{-3}\%$. The residuals of the MVDR are uncorrelated with other cluster properties like temperature, cluster radius, baryonic mass surface density, and redshift. These characteristics are reminiscent of the MVDR for individual galaxies, albeit about ten times larger characteristic acceleration scale. The cluster baryon fraction falls short of the cosmic value, exposing a problem: the discrepancy increases systematically for clusters of lower mass and lower baryonic acceleration.

Large Magellanic Cloud Microlensing Optical Depth with Imperfect Event Selection
Creators: name: Bennett, David P.

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I present a new analysis of the MACHO Project 5.7 year Large Magellanic Cloud (LMC) microlensing data set that incorporates the effects of contamination of the microlensing event sample by variable stars. Photometric monitoring of MACHO LMC microlensing event candidates by the EROS and OGLE groups has revealed that one of these events is likely to be a variable star, while additional data has confirmed that many of the other events are very likely to be microlensing. This additional data on the nature of the MACHO microlensing candidates is incorporated into a simple likelihood analysis to derive a probability distribution for the number of MACHO microlens candidates that are true microlensing events. This analysis shows that 10-12 of the 13 events that passed the MACHO selection criteria are likely to be microlensing events, with the other 1-3 being variable stars. This likelihood analysis is also used to show that the main conclusions of the MACHO LMC analysis are unchanged by the variable star contamination. The microlensing optical depth toward the LMC is = 1.0 +/- 0.3 * 10^{-7}. If this is due to microlensing by known stellar populations, plus an additional population of lens objects in the Galactic halo, then the new halo population would account for 16% of the mass of a standard Galactic halo. The MACHO detection exceeds the expected background of 2 events expected from ordinary stars in standard models of the Milky Way and LMC at the 99.98% confidence level. The background prediction is increased to 3 events if maximal disk models are assumed for both the MilkyWay and LMC, but this model fails to account for the full signal seen by MACHO at the 99.8% confidence level.

The following taxa are considered valid subgenera of the genus Xantholinus: Typhlolinus Reitter, 1908; Helicophallus Coiffait, 1956, and obviously Xantholinus s. str. (linearisgroup); Neohypnus Coiffait & Saiz, 1964 = Sungaria Bordoni, 2003, syn. n. The following new combinations are subsequently established: Neohypnus mandschuricus (Bernhauer, 1923), comb. n. (East Russia, S Mongolia, Korea); Neohypnus meridionalis (Bordoni, 2003), comb. n. (Guanxi); Neohypnus rougemonti (Bordoni, 2003), comb. n. (Zhejiang, Shaanxi). The genus Sylea Bordoni, 2001 is not a synonym of Vulda Jaquelin du Val, 1853, and is here a revalidated genus, and Xantholinus kazachstanicus Janak, 1979 does not belong to Vulda or Sylea, but it certainly belongs to a different genus, till now pending a formal name, whose delimitation and possible description need additional available material.

description: One advantage of quantum algorithms over classical computation is the possibility to spread out, process, analyse and extract information in multipartite configurations in coherent superpositions of classical states. This will be discussed in terms of quantum state identification problems based on a proper partitioning of mutually orthogonal sets of states. The question arises whether or not it is possible to encode equibalanced decision problems into quantum systems, so that a single invocation of a filter used for state discrimination suffices to obtain the result.

How clinical nursing instructors define and construct interpersonal boundaries with their students
Creators: name: Zieber, Mark Richard Pijl
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to examine how nursing instructors define and construct interpersonal boundaries with the students they teach. While the last two decades have seen a transition in the philosophy of teaching and learning in nursing, boundary construction within the new direction has not yet been fully examined. The literature reflects a wide variety of opinions on what constitutes an interpersonal boundary in the context of a teaching practice. Data collection involved open-ended interviews with eight nursing instructors. The data were analyzed from the perspective of naturalistic inquiry and utilized a constant comparative technique. The study found that interpersonal boundaries were defined as limitations in the relational dynamics between the instructor and student. The construction of boundaries was a process that involved a series of boundary crossings between the delineation of professional and personal. The process of boundary crossing was enacted in the level of connection between the clinical participants and the amount and depth of self disclosure.

description: The onset of planet formation in protoplanetary disks is marked by the growth and crystallization of sub-micron-sized dust grains accompanied by dust settling toward the disk mid-plane. Here we present infrared spectra of disks around brown dwarfs and brown dwarf candidates. We show that all three processes occur in such cool disks in a way similar or identical to that in disks around low- and intermediate-mass stars. These results indicate that the onset of planet formation extends to disks around brown dwarfs, suggesting that planet formation is a robust process occurring in most young circumstellar disks.

This allows for the accurate calculation of the real-time correlation functions in this strongly interacting quantum system for arbitrary distances and times.

description: The relevance of encounters on the destruction of protoplanetary discs in the Orion Nebula Cluster (ONC) is investigated by combining two different types of numerical simulation. First, star-cluster simulations are performed to model the stellar dynamics of the ONC, the results of which are used to investigate the frequency of encounters, the mass ratio and separation of the stars involved, and the eccentricity of the encounter orbits. The results show that interactions that could influence the star-surrounding disc are more frequent than previously assumed in the core of the ONC, the so-called Trapezium cluster. Second, a parameter study of star-disc encounters is performed to determine the upper limits of the mass loss of the discs in encounters. For simulation times of $\sim$ 1-2 Myr (the likely age of the ONC) the results show that gravitational interaction might account for a significant disc mass loss in dense clusters. Disc destruction is dominated by encounters with high-mass stars, especially in the Trapezium cluster, where the fraction of discs destroyed due to stellar encounters can reach 10-15%. These estimates are in accord with observations of (Lada et al. 2000) who determined a stellar disc fraction of 80-85%. Thus, it is shown that in the ONC - a typical star-forming region - stellar encounters do have a significant effect on the mass of protoplanetary discs and thus affect the formation of planetary systems.

description: In vibrational strong coupling (VSC), molecular vibrations strongly interact with the modes of an optical cavity to form hybrid light-matter states known as vibrational polaritons. Experiments show that the kinetics of thermally activated chemical reactions can be modified by VSC. Transition-state theory, which assumes that internal thermalization is fast compared to reactive transitions, has been unable to explain the observed findings. Here, we carry out kinetic simulations to understand how dissipative processes, namely those that VSC introduces to the chemical system, affect reactions where internal thermalization and reactive transitions occur on similar timescales. Using the Marcus-Levich-Jortner type of electron transfer as a model reaction, we show that such dissipation can change reactivity by accelerating internal thermalization, thereby suppressing nonequilibrium effects that occur in the reaction outside the cavity. This phenomenon is attributed mainly to cavity decay (i.e., photon leakage), but a supporting role is played by the relaxation between polaritons and dark states. When nonequilibrium effects are already suppressed in the bare reaction (the reactive species are essentially at internal thermal equilibrium throughout the reaction), we find that reactivity does not change significantly under VSC. Connections are made between our results and experimental observations.

description: The purpose of this study is to evaluate the risks faced by fed cattle producers. With the development of livestock insurance programs as part of the Agricultural Risk Protection Act of 2000, a thorough investigation into the probabilistic measures of individual risk factors is needed. This research jointly models cattle production yield risk factors, using a multivariate dynamic regression model. A multivariate framework is necessary to characterize yield risk in terms of four yield factors (dry matter feed conversion, averaged daily gain, mortality, and veterinary costs), which are highly correlated. Additionally, a conditional Tobit model is used to handle censored yield variables (e.g., mortality). The proposed econometric model estimates parameters that influence the mean and variance of each production yield factor, as well as the covariance between variables. Following the model fitting using a maximum likelihood approach, simulation methods allow for profits, revenue, and gross margins to be evaluated given different assumptions concerning volatility among other shocks. The profit function is composed of random draws, based on conditioning variables, as well as parameter estimates. Shocks to variability, yield factors, or prices allow for a visual representation of the vulnerability of cattle feeder profits to these shocks.

description: A new species of Trechus from the Oromia Province (Ethiopia) is described in the present note. This new taxon shows some peculiar characters, such as a much swollen abdomen of pseudophysiogastric aspect, a feature shared by other high altitude Trechinae, as for instance Queinnectrechus Deuve, 1992 from Asia. The integuments are glabrous; the antennae are short; the pronotum is larger than long, with regularly rounded sides and hind angles; the elytrae are short and rounded (pseudophysiogastric) with the first six striae well engraved, on the third of them two discal foveolate setae are well visible. The aedeagus is big and stout, abruptly narrowing at the tip (in lateral view), with a small botton slanting upwards; the copulatory piece is big and well sclerified, triangular, with a more or less sharpened tip. Well recognizable for the “pseudophysiogastric” aspect, Trechus (Trechus) ericalis n.sp. belongs to the bipartitus group.

Introducing enterprise education: Innovative curriculum at three case study schools in Australia

description: This thesis investigates three Australian schools conducting enterprise education, an approach to education that is significantly different to the curriculum set by governments and their education authorities. It explores why schools decide to develop and implement enterprise education at a local level and the implications that occur as a result. The thesis discusses the tensions between state-set curriculum and school-developed curriculum to reveal the risks and vulnerabilities faced by teachers when they diverge from the established practices of school curriculum.The research was conducted via semi-structured interviews with 17 participants at three case study schools located in three different states of Australia. The schools were in the process of developing or already conducting enterprise education on a large scale in terms of the number of students within a cohort and the time allocated to enterprise education during a school year.The participants perceived Australia’s school system as fixated on an outcomes-based curriculum that made the achievement of grades the ultimate goal of school education. They also perceived a need to develop students’ thinking and social skills and personal capabilities beyond the curriculum as imposed by educational authorities. The introduction of enterprise education was seen as a means to address the imbalance between students’ knowledge of subjects and the development of students more holistically. Overall, the aim was to provide students with agency in life by centring the curriculum on who they were and who they were becoming.The teachers involved in curriculum development found that the risk of creating something new whilst collaborating intensely with other teachers meant they were experiencing, like their students, a form of enterprise education. However, the risk provided teachers with great rewards due to the successes of their students and the learning from each other. Participating in the development and implementation of their own curriculum also gave them an increased sense of agency.The research therefore reveals many of the issues inherent in outcomes-based curriculum and excessive emphasis on achievement of grades. It demonstrates that it is feasible for schools to develop and implement curriculum that can work alongside or in conjunction with state-set curriculum when school context allows it. To make significant change in curriculum at the local level, it takes educators who are prepared to experience risk and vulnerability in the process.

description: The issue of extending geographic indicator protection to products other than wines and spirits has created wide divergences between demandeurs and opponent countries at the WTO. This article examines the economic impacts of the proposals submitted at the WTO by these two groups of countries, focusing mainly on market access, generic names and impacts for the consumer in North America. Results from our survey show that reducing tariff and non-tariff barriers in North America would be more important in improving market access for EU geographical indications (GIs) than would GI extension. In addition, it would appear that North American consumers may not benefit from extension of protection to products other than wines and spirits..

description: Surface-enhanced optical third-harmonic generation (THG) is observed in silver island films. The THG intensity from Ag nanoparticles is enhanced by more than two orders of magnitude with respect to the THG intensity from a smooth and homogeneous silver surface. This enhancement is attributed to local plasmon excitation and resonance of the local field at the third-harmonic wavelength. The diffuse and depolarized component of the enhanced THG is associated with the third-order hyper-Rayleigh scattering in a 2-D random array of silver nanoparticles.

description: The quantum repeater protocol is a promising approach to implement long-distance quantum communication and large-scale quantum networks. A key idea of the quantum repeater protocol is to use long-lived quantum memories to achieve efficient entanglement connection between different repeater segments with a polynomial scaling. Here we report an experiment which realizes efficient connection of two quantum repeater segments via on-demand entanglement swapping by the use of two atomic quantum memories with storage time of tens of milliseconds. With the memory enhancement, scaling-changing acceleration is demonstrated in the rate for a successful entanglement connection. The experimental realization of entanglement connection of two quantum repeater segments with an efficient memory-enhanced scaling demonstrates a key advantage of the quantum repeater protocol, which makes a cornerstone towards future large-scale quantum networks.

description: The Israeli citrus export sector was liberalized in 1991 with the aim to increase citrus growers' income and to improve overall efficiency of the international citrus marketing channel. However, the former government export monopoly's activities were mainly taken over by four large companies accounting for over 90% of total Israeli citrus market exports. In addition, citrus exporters maintained the monopoly's consignment system, substantially limiting transparency on how the grower price is determined. This lead the government to intervene in the newly liberalized market by implementing a minimum price agreement in the 1994/95 season to protect citrus growers against exporters' abuse of market power. In this paper we analyze whether market power was exerted by exporting companies over citrus growers in the form of asymmetric price transmission. Our study is unique in that it investigates vertical price transmission across international borders, i.e. in the context of Israeli grapefruit exports to France. We explicitly account for possible changes in exporters' pricing behaviour in the post-liberalization period. We apply an error correction model (ECM) to disaggregated firm-level Israeli grower price and French import price data. An ECM is estimated individually for each of the major exporting companies within a seemingly unrelated regression (SUR) framework. We find asymmetric price transmission in the first years after liberalisation, but symmetry in the second half of the 1990s. Our results indicate that growers' losses due to asymmetry amounted to as much as 2.5% of their total revenues. Our results suggest that liberalization improved the efficiency of the Israeli citrus international marketing channel, but that this took time and was probably accelerated by government intervention.

description: We present the unfiltered ROTSE-III light curve of the optical transient associated with GRB 050319 beginning 4 s after the cessation of gamma-ray activity. We fit a power-law function to the data using the revised trigger time given by Chincarini et al. (2005), and a smoothly broken power-law to the data using the original trigger disseminated through the GCN notices. Including the RAPTOR data from Wozniak et al. (2005), the best fit power-law indices are alpha=-0.854 (+/- 0.014) for the single power-law and alpha_1=-0.364 (+/- 0.020), alpha_2= -0.881 (+/- 0.030), with a break at t_b = 418 (+/- 30) s for the smoothly broken fit. We discuss the fit results with emphasis placed on the importance of knowing the true start time of the optical transient for this multi-peaked burst. As Swift continues to provide prompt GRB locations, it becomes more important to answer the question, "when does the afterglow begin" to correctly interpret the light curves.

description: In this paper, we propose a novel receiver structure for single-carrier transmission with frequency domain equalization (FDE) that is exposed to power amplifier (PA) nonlinearities. A two-stage approach is adopted, in which linear communication channel is equalized at the first stage, and it is followed by a post-distortion where nonlinear distortion is reduced. In literature, nonlinear processing techniques are proposed, which performs memoryless compensation of nonlinear distortion together with FDE. However, in this study, we show that even if a memoryless nonlinearity exists, the received signal is impaired by nonlinear inter-symbol-interference. Therefore, we propose a class of symbol rate post-distortion techniques, which use neighboring received symbols to suppress the nonlinear interference. Two different post-distortion techniques, Gaussian process regression (GPR) and neural network (NN) based post-distorters, are considered. Also, a decision metric, combining outputs of fractional delayed bank of FDE's after post-distortion, is proposed to overcome performance degradation of FDE for frequency selective channels under nonlinear distortion. Performances of the proposed techniques are compared with that of the state-of-the-art techniques in terms of bit error rate and achievable information rate metrics via simulations. Simulation results demonstrate that GPR and NN based post-distortion methods together with bank of FDE outperform state-of-the-art techniques.

description: A supersymmetric vacuum has to obey a set of constraints on fluxes as well as first order differential equations defined by the G-structures of the internal manifold. We solve these equations for type IIB supergravity with SU(3) structures. The 6-dimensional internal manifold has to be complex, the axion/dilaton is in general non-holomorphic and a cosmological constant is only possible if the SU(3) structures are broken to SU(2) structures. The general solution is expressed in terms of one function which is holomorphic in the three complex coordinates and if this holomorphic function is constant, we obtain a flow-type solution and near poles and zeros we find the so-called type-A and type-B vacuum.
