description: We present extensive simulations of a quantum version of the Hopfield Neural Network to explore its emergent behavior. The system is a network of $N$ qubits oscillating at a given $Ω$ frequency and which are coupled via Lindblad jump operators built with local fields $h_i$ depending on some given stored patterns. Our simulations show the emergence of pattern-antipattern oscillations of the overlaps with the stored patterns similar (for large $Ω$ and small temperature) to those reported within a recent mean-field description of such a system, and which are originated deterministically by the quantum term including $s_x^i$ qubit operators. However, in simulations we observe that such oscillations are stochastic due to the interplay between noise and the inherent metastability of the pattern attractors induced by quantum oscillations, and then are damped in finite systems when one averages over many quantum trajectories. In addition, we report the system behavior for large number of stored patterns at the lowest temperature we can reach in simulations (namely $T=0.005\, T_C$). Our study reveals that for small-size systems the quantum term of the Hamiltonian has a negative effect on storage capacity, decreasing the overlap with the starting memory pattern for increased values of $Ω$ and number of stored patterns. However, it also impedes the system to be trapped for long time in mixtures and spin-glass states. Interestingly, the system also presents a range of $Ω$ values for which, although the initial pattern is destabilized due to quantum oscillations, other patterns can be retrieved and remain stable even for many stored patterns, implying a quantum-dependent nonlinear relationship between the recall process and the number of stored patterns.

description: This paper is based on an European study on products with a Protected Denomination of Origin and particularly analyses four cheeses and their supply chain : Parmigiano-Reggiano, the Grana Padano, the Comté and the Cantal. After short theoretical considerations concerning technological development in agriculture, the importance for a PDO product to be very specific in order to differentiate itself from substitutes product is explained. This specificity must have a link with the product terroir. This paper looks then at how the link between a product and its terroir can be defined in the product's specification (code of practices) and how it can be threatened by technological changes. A supply chain can indeed take advantage of a loose code of practice to reduce its costs production and standardise its production, but such a development not necessarily generates overall benefits for the supply chain. The players' strategy might however rather tend to reinforce the specific technological trajectory of the product in order to strengthen its specificity. We will finally see how the co-ordination within a supply chain and the actors' motivation are important to preserve the product uniqueness.
X-ray Spectra and Pulse Frequency Changes in SAX J2103.5+4545

description: The November 1999 outburst of the transient pulsar SAX J2103.5+4545 was monitored with the large area detectors of the Rossi X-Ray Timing Explorer until the pulsar faded after a year. The 358 s pulsar was spun up for 150 days, at which point the flux dropped quickly by a factor of 7, the frequency saturated and, as the flux continued to decline, a weak spin-down began. The pulses remained strong during the decay and the spin-up/flux correlation can be fit to the Ghosh and Lamb derivations for the spin-up caused by accretion from a thin, pressure-dominated disk, for a distance 3.2 kpc and a surface magnetic field 1.2 10^{13} Gauss. During the bright spin-up part of the outburst, the flux was subject to strong orbital modulation, peaking 3 days after periastron of the eccentric 12.68 day orbit, while during the faint part, there was little orbital modulation. The X-ray spectra were typical of accreting pulsars, describable by a cut-off power-law, with an emission line near the 6.4 keV of K alpha fluorescence from cool iron. The equivalent width of this emission did not share the orbital modulation, but nearly doubled during the faint phase, despite little change in the column density. The outburst could have been caused by an episode of increased wind from a Be star, such that a small accretion disk is formed during each periastron passage. A change in the wind and disk structure apparently occurred after 5 months such that the accretion rate was no longer modulated or the diffusion time was longer. The distance estimate implies the X-ray luminosity observed was between 1 10^{36} ergs s^{-1} and 6 \times 10^{34} ergs s^{-1}, with a small but definite correlation of the intrinsic power-law spectral index.

description: Quantum key distribution (QKD) enables two remote parties to share encryption keys with security based on the laws of physics. Continuous variable (CV) QKD with coherent states and coherent detection integrates well with existing telecommunication networks. However, thus far, long-distance CV-QKD has only been demonstrated using a highly complex scheme where the local oscillator is transmitted, opening security loopholes for eavesdroppers and limiting its potential applications. Here, we report a long-distance CV-QKD experiment with a locally generated local oscillator over a 100 km fiber channel with a total loss of 15.4 dB. This record-breaking distance is achieved by controlling the phase-noise-induced excess noise through a machine-learning framework for carrier recovery and optimizing the modulation variance. We implement the full CV-QKD protocol and demonstrate the generation of keys secure against collective attacks in the finite-size regime. Our results mark a significant milestone for realizing CV quantum access networks with a high loss budget, and pave the way for large-scale deployment of secure QKD.

description: Im Projekt Foresight4Youth anlässlich des Wissenschaftsjahres 2018 „Zukunft der Arbeit“ wurden mit über 100 Jugendlichen aus prekären Verhältnissen Workshops zur Zukunftsvisualisierung durchgeführt. Hierbei wurden Einstellungen und Verhaltensweisen bezüglich Mediennutzung, Nachrichtenaufnahme und persönliche sowie gesellschaftliche Zukunftsentwicklungen erfragt. Diese wurden mit einer Vergleichsgruppe von 34 Gymnasiasten der Oberstufe vergleichen, wobei sich zahlreiche Gemeinsamkeiten aber auvh Unterschiede ergaben. In beiden Gruppen ist beobachtbar, dass Fernsehen und Zeitungen durch Smartphone und Internet in allen Bereichen des Alltags inkl. Nachrichtenaufnahme deutlich zurückgedrängt wurden. Insgesamt zeigt die gymnasiale Vergleichsgruppe größeres Interesse an Nachrichten und verwendet ein größeres Spektrum an Medien und Informationskanälen. Außerdem ist sie besser über Zukunftsentwicklungen informiert und beurteilt die Auswirkung auf die Zukunft differenzierter. Nichts desto trotz sind viele zukunftsassoziierte Begriffe, wie beispielsweise „Internet of Things“ oder „Co-Working Spaces“ auch in der Vergleichsgruppe weitestgehend unbekannt. Während die Jugendlichen, unabhängig vom sozioökonomischen Status, fast durchgängig der Meinung sind, dass Fachwissen, Fleiß, Pünktlichkeit, Genauigkeit ebenso wichtig sind wie Teamfähigkeit und Kommunikationsfähigkeit, zeigen verschiedene Studien, dass insbesondere Digital- und Computer-Kompetenzen, sowie Problemlösefähigkeit das Fachwissen und die „typisch deutschen Tugenden“ Fleiß, Pünktlichkeit und Genauigkeit längst in ihrer Bedeutung für den Arbeitsmarkt weit hinter sich gelassen haben. Besonders bemerkenswert ist jedoch, dass die Jugendlichen beider Gruppen sowohl Programmierkenntnissen, als auch allgemeinen Computerkenntnissen kaum Bedeutung beimessen.

description: We used 3.1 million spectroscopically labelled sources from the Sloan Digital Sky Survey (SDSS) to train an optimised random forest classifier using photometry from the SDSS and the Widefield Infrared Survey Explorer (WISE). We applied this machine learning model to 111 million previously unlabelled sources from the SDSS photometric catalogue which did not have existing spectroscopic observations. Our new catalogue contains 50.4 million galaxies, 2.1 million quasars, and 58.8 million stars. We provide individual classification probabilities for each source, with 6.7 million galaxies (13%), 0.33 million quasars (15%), and 41.3 million stars (70%) having classification probabilities greater than 0.99; and 35.1 million galaxies (70%), 0.72 million quasars (34%), and 54.7 million stars (93%) having classification probabilities greater than 0.9. Precision, Recall, and F1 score were determined as a function of selected features and magnitude error. We investigate the effect of class imbalance on our machine learning model and discuss the implications of transfer learning for populations of sources at fainter magnitudes than the training set. We used a non-linear dimension reduction technique, Uniform Manifold Approximation and Projection (UMAP), in unsupervised, semi-supervised, and fully-supervised schemes to visualise the separation of galaxies, quasars, and stars in a two-dimensional space. When applying this algorithm to the 111 million sources without spectra, it is in strong agreement with the class labels applied by our random forest model.

description: In this work we investigate observational signatures of a primordial power spectrum with exponential infrared suppression, motivated by the choice of a non-oscillatory vacuum in a bouncing and inflationary geometry within Loop Quantum Cosmology (LQC). We leave the parameter that defines the scale at which suppression occurs free and perform a Bayesian analysis, comparing with CMB data. The data shows a preference for some of the suppression to be within the observable window. Guided by this analysis, we choose concrete illustrative values for this parameter. We show that the model affects only slightly the parity anomaly, but it is capable of alleviating the lensing and power suppression anomalies.

description: We argue that the Karch-Randall compactification is holographically dual to a 4-d conformal field theory coupled to gravity on Anti de Sitter space. Using this interpretation we recover the mass spectrum of the model. In particular, we find no massless spin-2 states. By giving a purely 4-d interpretation to the compactification we make clear that it represents the first example of a local 4-d field theory in which general covariance does not imply the existence of a massless graviton. We also discuss some variations of the Karch-Randall model discussed in the literature, and we examine whether its properties are generic to all conformal field theory.

description: We address the classical and quantum marginal problems, namely the question of simultaneous realizability through a common probability density in phase space of a given set of compatible probability distributions. We consider only distributions authorized by quantum mechanics, i.e. those corresponding to complete commuting sets of observables. For four-dimensional phase space with position variables qi and momentum variables pj, we establish the two following points: i) given four compatible probabilities for (q1,q2), (q1,p2), (p1,q2) and (p1,p2), there does not always exist a positive phase space density rho({qi},{pj}) reproducing them as marginals; this settles a long standing conjecture; it is achieved by first deriving Bell-like inequalities in phase space which have their own theoretical and experimental interest. ii) given instead at most three compatible probabilities, there always exist an associated phase space density rho({qi},{pj}); the solution is not unique and its general form is worked out. These two points constitute our ``three marginal theorem''.

description: 455. Polietes Rondani, 1866a: 71, 91.
 ORIGINALLY INCLUDED SPECIES: Musca lardaria Fabricius, 1781.
 TYPE SPECIES: Musca lardaria Fabricius, 1781, by original designation.
 CURRENT STATUS: Valid genus [teste Pont (1986b: 85)].
FAMILY: MUSCIDAE.
 456. Polionoma Rondani, 1856: 107.
ORIGINALLY INCLUDED SPECIES: None.
 FIRST INCLUDED SPECIES: Sapromyza obsoleta Fallén, 1820 (in Coquillett, 1910: 593).
 TYPE SPECIES: Sapromyza obsoleta Fallén, 1820, by subsequent designation (Coquillett, 1910: 593).
 CURRENT STATUS: Junior synonym of Sapromyza Fallén, 1810 [teste Rondani (1868b: 36; 1868c: 234)].
FAMILY: LAUXANIIDAE.
 REMARKS: Originally proposed in Rondani (1856) without included species. Although placed by Rondani (1868b: 36; 1868c: 234) in synonymy with Sapromyza, no species were expressly included for Polionoma there. Coquillett (1910: 593) is interpreted here as the first to expressly include a species (Sapromyza obsoleta Fallén, 1820), and he designated it as the type of Polionoma Rondani, 1856. The name has not been treated in any of the regional Diptera catalogs so we follow Rondani (1868c, d) in treating Polionoma Rondani, 1856 as a junior synonym of Sapromyza Fallén, 1810.
 [Polyetes] Rondani, 1877c: 302.
 CURRENT STATUS: Incorrect subsequent spelling of Polietes Rondani, 1866.
FAMILY: MUSCIDAE.
REMARKS: Criteria for making this name available as an emendation were not found to be fulfilled in this work.
 [Porphirops] Rondani, 1856: 142, 145, 220.
 CURRENT STATUS: Incorrect subsequent spelling of Porphyrops Meigen, 1824.
FAMILY: DOLICHOPODIDAE.
 REMARKS: The earliest mention of Porphyrops Meigen, 1824 using the spelling “ Porphirops ” that we have found in this study is in Macquart (1834a: “explication des planches”, page 7). Porphirops would be eligible as an unjustified emendation in Macquart (1834a) by virtue of similar spelling changes in two or more names from “y” to “i” in the same work, but as Macquart (1834a: 434) also used the original spelling Porphyrops, his treatment of the name is ambiguous. We thus follow ICZN Code Article 33.5 in treating this spelling as an incorrect subsequent spelling. Porphyrops Meigen, 1824 is an objective senior synonym of Argyra Macquart, 1834. However, due to prevailing usage, Argyra is retained here for stability following Dyte & Smith (1980: 458). An application to the ICZN Commission is warranted to either suppress Porphyrops Meigen, 1824 and conserve Argyra Macquart, 1834 or to deem reversed synonymy when these genus-group names are considered synonyms of each other.

description: Additional file 6: Supplemental Figure 6. Sows and piglets have significantly different gut microbiome compositions. Shotgun metagenomic sequencing was performed for fecal samples from 18 mother sows that were collected at days 37 and 114 of gestation, and from fecal swabs from 3 offspring of each pig collected 10 days after delivery. A) An NMDS plot representing the Bray-Curtis beta diversity between the 90 samples (36 sow and 54 piglet) was generated. The microbiome compositions of sows are significantly different from that of piglets (P = 1e-5). B) A heatmap was generated using the 32 bacterial species with relative abundance >1% among either sows or piglets. For each sample, the heatmap shows the relative abundance of each species. Consistent with the NMDS plot, the heatmap separates into two major phylogenetic branches, with sows on the left and piglets on the right. Four sow samples cluster within the piglet branch and are noted below the heatmap.
A Cyberattack Detection-Isolation Scheme For CAV Under Changing Driving Environment

description: Under a changing driving environment, a Connected Autonomous Vehicle (CAV) platoon relies strongly on the acquisition of accurate traffic information from neighboring vehicles as well as reliable commands from a centralized supervisory controller through the communication network. Even though such modalities are imperative to ensure the safe and efficient driving performance of CAVs, they led to multiple security challenges. Thus, a cyberattack on this network can corrupt vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication, which can lead to unsafe or undesired driving scenarios. Hence, in this paper, we propose a cyberattack detection-isolation algorithm comprised of a unified V2V and V2I cyberattack detection scheme along with a V2I isolation scheme for CAVs under changing driving conditions. The proposed algorithm is constructed using a bank of residual generators with Lyapunov function-based performance guarantees, such as disturbance-to-state stability, robustness, and sensitivity. Finally, we showcase the efficacy of our proposed algorithm through extensive Monte-Carlo simulations using real-world highway and urban driving data. The results show that the proposed algorithm can enhance the cybersecurity of CAVs by detecting cyberattacks on CAV platoons and isolating infrastructure-level traffic manipulation.

description: Multiple Instance Learning (MIL) is a weak supervision learning paradigm that allows modeling of machine learning problems in which labels are available only for groups of examples called bags. A positive bag may contain one or more positive examples but it is not known which examples in the bag are positive. All examples in a negative bag belong to the negative class. Such problems arise frequently in fields of computer vision, medical image processing and bioinformatics. Many neural network based solutions have been proposed in the literature for MIL, however, almost all of them rely on introducing specialized blocks and connectivity in the architectures. In this paper, we present a novel and effective approach to Multiple Instance Learning in neural networks. Instead of making changes to the architectures, we propose a simple bag-level ranking loss function that allows Multiple Instance Classification in any neural architecture. We have demonstrated the effectiveness of our proposed method for popular MIL benchmark datasets. In addition, we have tested the performance of our method in convolutional neural networks used to model an MIL problem derived from the well-known MNIST dataset. Results have shown that despite being simpler, our proposed scheme is comparable or better than existing methods in the literature in practical scenarios. Python code files for all the experiments can be found at https://github.com/amina01/ESMIL.

description: Within the minimum model of neutron stars (NS) consisting of neutrons, protons and electrons, a new approach is proposed for inferring the symmetry energy of super-dense neutron-rich nucleonic matter above twice the saturation density $ρ_0$ of nuclear matter directly from integrating iteratively barotropic pressures in both neutron stars and heavy-ion reactions. Simultaneously, the proton fraction of NSs at $β$ equilibrium is extracted as a function of baryon density from the same procedure. An application of this approach using the NS pressure from GW170817 and the pressure in cold symmetric nuclear matter (SNM) extracted earlier by analyzing nuclear collective flow data in relativistic heavy-ion collisions provides a useful constraining band for the symmetry energy above $2ρ_0$.

ROAD and K2 photometry of V348 Sgr: probing the pulsation dust connection

Year: 2019
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: V348 Sgr is simultaneously an active hot R Coronae Borealis (RCB) variable, a peculiar extreme helium star, and the hydrogen-deficient central star of a planetary nebula. Explaining the RCB-type variability has been difficult since the star spends much of its time at minimum light. We present new ground-based multicolour photometry covering 5 observing seasons and 80 days of continuous photometry from space. The latter demonstrate small-amplitude (< 0.01 mag.) variability at maximum light on timescales typical for strange-mode pulsation in hot helium supergiants. These could provide a trigger for frequent dust-production episodes; other mechanisms must also be considered. Multi-colour photometry probes the reddening properties of extinction events from minimum to maximum light. The latter are comparable with extinction events due to carbonaceous grains seen in cooler RCB stars. Minimal reddening at minimum light is indicative that starlight scattered from circumstellar dust into the line of sight dominates transmitted light.

description: In this work, the performances of two ionic liquid matrices (ILMs) with the same ammonium counterpart for mass spectrometric analysis of the insoluble and soluble sucralfate were compared. Matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS) was performed assisted by the butylammonium salts of α-cyano-hydroxycinnamic acid (CHCAB) and 2,5-dihydroxybenzoic acid (DHBB). CHCAB has a higher IE than DHBB, but better optical properties. CHCAB is more suitable for the analysis of sucralfate, although molecular ions of both compounds were detectable only with low intensities. Thus, optical properties of ILMs are crucial to enhance the sensitivity of MALDI MS detection of polysulfated oligosaccharides.

description: We investigate the classical geometry corresponding to a collection of fractional D3 branes in the orbifold limit of an ALE space. We discuss its interpretation in terms of the world-volume gauge theory on the branes, which is in general a non conformal N=2 Yang-Mills theory with matter. The twisted fields reproduce the perturbative behaviour of the gauge theory. We regulate the IR singularities for both twisted and untwisted fields by means of an enhancon mechanism qualitatively consistent with the gauge theory expectations. The five-form flux decreases logarithmically towards the IR with a coefficient dictated by the gauge theory beta-functions.

description: Additional file 7: Supplemental Figure 7. The relative abundance of bacterial taxa in a sow does not correlate with the relative abundance of that taxa in her offspring. Linear regression analyses was performed for each of the 8 bacterial species with average relative abundance >1% across all samples and that were present in at least two-thirds of all samples. For each piglet, the relative abundance of each bacterial species in its mother at Day 114 was plotted (X-axis) against the relative abundance of that species in the piglet 10 days after delivery (Y-axis). Fecal swabs from three piglets from each sow were sequenced. There were no significant correlations between bacterial species in mother and offspring in any of the eight species (Adj. P > 0.3).

description: New virial black-hole mass estimates are presented for a sample of 72 AGN covering three decades in optical luminosity. Using a model in which the AGN broad-line region (BLR) has a flattened geometry, we investigate the M_{bh)-L_{bulge} relation for a combined 90-object sample, consisting of the AGN plus a sample of 18 nearby inactive elliptical galaxies with dynamical black-hole mass measurements. It is found that, for all reasonable mass-to-light ratios, the M_{bh}-L_{bulge} relation is equivalent to a linear scaling between bulge and black-hole mass. The best-fitting normalization of the M_{bh}-M_{bulge} relation is found to be M_{bh}=0.0012M_{bulge}, in agreement with recent black-hole mass studies based on stellar velocity dispersions. Furthermore, the scatter around the M_{bh}-L_{bulge} relation for the full sample is found to be significantly smaller than has been previously reported (Δ\log M_{bh}=0.39 dex). Finally, using the nearby inactive elliptical galaxy sample alone, it is shown that the scatter in the M_{bh}-L_{bulge} relation is only 0.33 dex, comparable to that of the M_{bh}-sigma relation. These results indicate that reliable black-hole mass estimates can be obtained for high redshift galaxies.

description: We present measurements of the component masses in 15 Cataclysmic Variables (CVs) - 6 new estimates and 9 improved estimates. We provide new calibrations of the relationship between superhump period excess and mass ratio, and use this relation to estimate donor star masses for 225 superhumping CVs. With an increased sample of donor masses we revisit the implications for CV evolution. We confirm the high mass of white dwarfs in CVs, but find no trend in white dwarf mass with orbital period. We argue for a revision in the location of the orbital period minimum of CVs to $79.6 \pm 0.2$ min, significantly shorter than previous estimates. We find that CV donors below the gap have an intrinsic scatter of only 0.005 R$_{\odot}$ around a common evolutionary track, implying a correspondingly small variation in angular momentum loss rates. In contrast to prior studies, we find that standard CV evolutionary tracks - without additional angular momentum loss - are a reasonable fit to the donor masses just below the period gap, but that they do not reproduce the observed period minimum, or fit the donor radii below 0.1 M$_{\odot}$.

description: Background and Purpose: The “Disability Attitudes in Health Care” scale contains 17 items and measures attitudes toward persons with disabilities in healthcare settings. This study aimed to analyze the psychometric properties of the Disability Attitudes in Health Care in order to improve its measurement quality. Materials and Methods: The Disability Attitudes in Health Care scale was administered to 272 students at a medical school. Rasch analysis was conducted to assess the category use, the overall fit of the model, and the person-item fit. Results: Compared to the previous 5-point Likert scoring system, the combination of category 1 (strongly disagree) and 2 (disagree), which transformed the Disability Attitudes in Health Care into a 4-point scale, was more appropriate. Items 2 and 13 had a poor fit with the model because of low construct homogeneity and low point-measure correlation, respectively; therefore, they were removed. However, there were not enough questions regarding the difficulty level for distinguishing medical students’ attitudes toward persons with disabilities more sensitively. Conclusions: The results of this study suggest that constructing Disability Attitudes in Health Care with 15 items and using a 4-category scoring method could help to increase the scale’s reliability and validity. The revised version of Disability Attitudes in Health Care could be of value to those who educate medical students and train rehabilitation professionals.IMPLICATIONS FOR REHABILITATIONConstructing a Disability Attitudes in Health Care scale with 15 items by using a 4-category scoring method could increase the reliability and validity of the scale.To improve the sensitivity of the Disability Attitudes in Health Care, it is necessary to add more difficult items to the scale.The Disability Attitudes in Health Care could be of value to those who educate medical students and train rehabilitation professionals.

description: We investigate a mean curvature flow obtained via elliptic regularization, and prove that it is not only a Brakke flow, but additionally a generalized BV flow proposed by Stuvard and Tonegawa. In particular, we show that the change in volume of the evolving phase can be expressed in terms of the generalized mean curvature of the Brakke flow.

description: In this paper, an attempt is made to describe the supply chains of two Greek PDO products, namely Peza olive oil and Zagara apples. Both products are produced in regional areas and constitute a major source of income for the local economies. Still, the differences noticed in their chain management underline the role of an industrial processor actor's participation : Peza olive oil is marketed in a highly competitive market in which many large private firms are operating, whereas Zagara apples, being marketed in the fresh product market, have a less typical and organised supply chain. The purpose of the paper is to analyse the structure of the two supply chains and to determine the relative importance of the PDO scheme on each product market performance. Thus, the whole set of participating actors is examined and the interrelations and the economic coordination between farmers, processors and retailers are highlighted. In addition, the competitive position of each product in the relevant market is investigated and compared to other competitive non-PDO products. The revealed strengths and weaknesses and the economic performance of the overall supply chains can provide some guidance, notably regarding the question whether, and when, it is worth to market a product under the PDO scheme.

description: Modification of active membrane surface is an auspicious way to enhance the membrane performance. In our study, a commercially available composite polyamide Nanofiltration (NF) membrane was modified by immobilizing silver doped TiO2 (Ag–TiO2) nanoparticles. Ag–TiO2 with different nanoparticles concentration (0.05, 0.1, and 0.5 wt. %) were coated on the surface of the membrane by a dip coating method. The evidence of successful coating was evaluated by Scanning Electron Microscopy coupled with Energy Dispersive Spectroscopy and Atomic Force Microscopy images. Moreover, the Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR), contact angle measurement and permeation tests were carried out in order to evaluate the membrane performance after coating. The antifouling property of the modified membrane was evaluated for Gram-positive (Bacillus subtilis) and Gram-negative (Escherichia coli) bacteria by colony counting method. The results indicated that the modified membranes keep efficient antibacterial efficacy against both types of bacteria. The bacterial growth reduced approximately 93% and 91% on the modified membrane as compared to the unmodified membrane for E.coli and B.subtilis, respectively. Ag–TiO2 nanoparticles imbedded nanofiltration membranes inhibit the biofilm formation and facilitate in cleaning membrane surface without using excessive chemical agents.

description: Tuning of spin-orbit coupling and electron correlation effects in pyrochlore iridates is considered for many interesting phenomena. We have investigated the temperature evolution of structural, magnetic and electronic properties in doped Y$_2$(Ir$_{1-x}$Ti$_{x}$)$_2$O$_7$ ($x$ = 0.0, 0.02, 0.05, 0.10 and 0.15) where the substitution of nonmagnetic Ti$^{4+}$ (3$d^0$) for Ir$^{4+}$ (5$d^5$) amounts to dilution of magnetic network and tuning of these parameters in opposite way. The system retains its original structural symmetry but local structural parameters show an evolution with Ti content. While the magnetic transition temperature is not largely influenced, both magnetic moment and magnetic frustration decreases with Ti doping. Magnetic relaxation measurement shows the parent compound Y$_2$Ir$_2$O$_7$ as well as its Ti doped analogues are in nonequilibrium magnetic state where the magnetic relaxation rate increases with Ti. Temperature dependent Raman measurements indicate no changes in structural symmetry, however, across the magnetic transition temperature an anomaly in A$_{1g}$ Raman mode is observed. Temperature dependent x-ray diffraction data also support the Raman spectroscopy data, however, an evolution of lattice parameters with temperature is observed. The electrical resistivity data of Y$_2$(Ir$_{1-x}$Ti$_{x}$)$_2$O$_7$ series exhibits insulating behavior throughout the temperature range, however, the resistivity decreases with Ti doping. The nature of charge conduction is found to follow power-law behavior in whole series but the validity of this model varies with temperature. A negative magnetoresistance has been observed at low temperature in present series which is explained with weak localized mechanism. Similar to other Ir based oxides, a crossover from negative to positive MR has been observed in present system.

Renormalizable Abelian-projected effective gauge theory derived from Quantum Chromodynamics II

description: In the previous paper\cite{KS00b}, we derived the Abelian projected effective gauge theory as a low energy effective theory of the SU(N) Yang-Mills theory by adopting the maximal Abelian gauge. At that time, we have demonstrated the multiplicative renormalizability of the propagators for the diagonal gluon and the dual Abelian anti-symmetric tensor field. In this paper, we show the multiplicative renormalizability of the Green's functions also for the off-diagonal gluon. Moreover we complement the previous results by calculating the anomalous dimension and the renormalization group functions which are undetermined in the previous paper.
