description: By using a theoretical formalism able to work in both real and k-spaces, the physical origin of the phenomenon of extraordinary transmission of light through quasi-periodic arrays of holes is revealed. Long-range order present in a quasiperiodic array selects the wavevector(s) of the surface electromagnetic mode(s) that allows an efficient transmission of light through subwavelength holes.

description: Stellar activity hinders the detection of small exoplanets with the radial velocity (RV) method, because it introduces spurious signals that can drown or mimic planetary signatures. It is therefore crucial to understand and filter out activity signals, especially in light of future small planet searches. We investigate ways to reduce activity jitter in RV time series using spectropolarimetric data sets in optical (ESPaDOnS@CHFT and NARVAL@TBL), and in near-infrared (nIR) with SPIRou@CHFT. We employ two approaches: 1) perform a chromatic study of typical stellar activity proxies, and 2) study a parametric selection of spectral lines to build a mask for Least-Square Deconvolution. The study is performed for EV Lac and AD Leo, two very active M dwarfs.

description: DNA methylation and microRNAs (miRNA) are two important forms of epigenetic modifications that play an important role in gene regulation in animals. Methylation at the carbon 5 position of cytosine residues is a fundamental layer of cellular differentiation through the control of transcriptional potential. MiRNA are small noncoding RNA molecules that regulate gene expression. Complete DNA methylomes for several organisms are now available; at the present, methylome of the domestic goat is unexplored. There is also still limited knowledge about miRNAs expression profiles in small ruminant species. Therefore, to contribute information on epigenetic modification in Capra hircus, we analysed the methylome and the miRNA population of three tissues (hypothalamus, pituitary and ovary) from 3 adult Saanen goats. We used Methylated DNA binding domain sequencing with enrichment of methylated DNA fragments and next generation sequencing. We produced least 23 million reads per sample, which were aligned to the goat reference genome. Further analyses were performed to identify peaks corresponding to hyper-methylated regions. We sequenced miRNAs expressed in the three tissues with Illumina high-throughput sequencing. Reads were mapped on the Capra hircus reference genome and both known and novel miRNAs, and miRNA target sites were identified using information collected in miRBase and using specific bioinformatic tools. This study produced a comprehensive miRNA profile related to the biology of goat. Furthermore, this is the first work dealing with methylome in Capra hircus: our preliminary results could provide new information for a deeper comprehension of epigenetic mechanisms of this species.

description: In this work, (3,5-bis((4,6-dichloro-1,3,5-triazine-2-yl)oxy)phenyl)methanol was obtained by reacting cyanuric chloride with 3,5-dihydroxybenzyl alcohol at 0 °C. Then, s-triazine bridged calixarene codded as L1 was obtained by reacting the compounds with 3,5-dihydroxybenzyl alcohol. Targed ligands, which we code as L2 and L3, were obtained from the reaction of the L1 coded compound with 4-aminobenzoic acid or 4-hydroxybenzoic acid, respectively. [MSalen/Saloph] capped s-triazine bridged calixarene complexes were obtained from the reaction of the L2 or L3 codded ligand and the [(MSalen/Saloph)2O] (M = Cr3+, Fe3+, Co3+) starting complexes in 1,4-dioxane media. The ligands and complexes were characterized by using 1H-NMR, FT-IR spectroscopy, UV-Vis spectroscopies, magnetic susceptibility, TGA-DTA and elemental analysis techniques. Metal contents of the complexes were determined by using ICP-AES spectroscopy. Calixarenes can be used in many areas such as chiral phase transfer catalyst, recognition of enantiomers, stationary phase in chromatography, recovery of heavy and precious metals molecules or ions from environmental wastes.

description: Sulfated tungstate catalyzed an efficient and ecofriendly protocol has been described for the synthesis of 2-substituted benzothiazoles. The corresponding benzothiazoles were obtained using a condensation reaction of 2-aminothiophenol with various aldehydes under ultrasound irradiation at room temperature. Various functional groups on the 2-aminothiophenol as well as on the aldehydes were tolerated to provide 2-substituted benzothiazoles derivatives in excellent yields. The faster reaction rate, solvent-free or mild reaction conditions, wide functional group compatibility, excellent yields, easy work-up procedure, and excellent catalyst recyclability are the advantages of this protocol. These advantages make this process more practicable, cost-effective, and environmentally benign.

description: Under suitable conditions, some twisted graphene multilayers and transition-metal dichalcogenides become Chern insulators, exhibiting the anomalous quantum Hall effect and orbital magnetization due to spontaneous valley polarization. We study interaction of a Chern insulator with circularly polarized light. The interaction energy contains an antisymmetric term that couples to the helicity of incident light. For a two-band Chern insulator, this term is expressed as an integral involving the Berry curvature of the system. Taking advantage of this interaction, we propose an experimental protocol for switching topological memory based on orbital magnetization by circularly polarized light. Moreover, two laser beams of opposite circular polarization can nucleate domains of opposite magnetization and thus produce an optically configurable domain wall carrying topologically protected chiral edge modes.

description: We point out that in the minimal supersymmetric standard model terms from the mixing of Higgs and Goldstone bosons which are connected to the renormalization of tan(beta) via Slavnov-Taylor identities give rise to corrections that do not vanish in the limit where the supersymmetric particles are much heavier than the Higgs bosons. These additional contributions have important phenomenological implications as they can lead to potentially large supersymmetric effects in DeltaM_d and to a significant increase of DeltaM_s relative to the standard model prediction for a light pseudoscalar Higgs A0. We calculate all the missing one-loop pieces and combine them with the known effective non-holomorphic terms to obtain improved predictions for the B_(d,s)-anti-B_(d,s) mass differences DeltaM_(d,s) and the branching ratios of B_(d,s) -> mu+mu- in the large tan(beta) regime of the minimal supersymmetric standard model with minimal flavor violation.

description: The validation and recovery of periodic signals in radial velocity data, especially low amplitude signals, is being complicated by the inherent stellar variations due to stellar activity. Using the time-series of high-resolution HARPS-N spectra of stars as well as the Sun, we are developing a new least-squares deconvolution method to determine at the same time a precise radial velocity and an independent measurement of the instantaneous line-of-sight magnetic flux on the visible stellar hemisphere. We present the new method as well as some first results.

description: Listeria monocytogenes (LM) is a foodborne pathogen responsible of listeriosis. In the spreading of this pathology, milk and dairy products are key reservoir for this pathogen1. Food processing represents one of the major steps that could be linked to LM growth. Inhibition of LM growth through competition of Lactococcus lactis (LAC) could represent a solution to this problem. Exoproteome of LM and two different strains of Lactic Acid Bacteria in co-culture have been studied in order to highlight mechanisms of bacterial competition useful to improve food safety. Two different strains of LAC and one strain of LM were cultivated in appropriate medium cultures (BHI), also in competition. Filtrated cultures (SECRETOME) were lyophilized and resuspended for proteomics analysis. Shotgun analysis on each secretome was performed on nano UPLC-MS system. Obtained data reveal, during competition, the higher production by LM of moonlighting protein Enolase and Glucose 6 Phosphate isomerase, of Septation ring formation regulator EzrA, involved into cell replication and the lower secretion of Endopeptidase P60. In parallel, L. lactis produced higher amounts of Secreted 45 kDa protein and switched from lantibiotic Nisin A production to Nisin Z production. In competition with LM, LAC strain investigated produce higher amounts of Secreted 45 kDa protein with peptidoglycan lytic activity and the selective secretion of Nisin Z probably to improve lantibiotic solubility in less acidic environment. Next step will be validation of obtained results in dairy products. These results are of interesting to design new strategies of fighting LM as contaminant in food from animal origin.

Chromospheric activity to age relationship among Sun-like stars

description: Most recent studies have established the viability of deriving usable chromospheric ages for solar-type stars older than 600 Myrs up to at least 6 Gyr, providing that mass and metallicity effects are accounted for. In order to avoid the uncertainty associated with the age determination of field stars, I characterised the long-term evolution of chromospheric activity on Sun-like stars by combining an empirical model of their rotation evolution in intermediate-age open clusters with rotation-activity relationships. The results indicate that the chromospheric activity evolution of Sun-like stars with ages between 1 and 6 Gyr and masses between 0.7 and 1.1 M☉ is steeper than the relationship R’HK ~ age^{-0.5} generally used.

description: We present results from a large volume simulation of Hydrogen reionization. We combine 3d radiative transfer calculations and an N-body simulation, describing structure formation in the intergalactic medium, to detail the growth of HII regions around high redshift galaxies. Our simulation tracks 1024^3 dark matter particles, in a box of co-moving side length 65.6 Mpc/h. This large volume allows us to accurately characterize the size distribution of HII regions throughout most of the reionization process. At the same time, our simulation resolves many of the small galaxies likely responsible for reionization. It confirms a picture anticipated by analytic models: HII regions grow collectively around highly-clustered sources, and have a well-defined characteristic size, which evolves from a sub-Mpc scale at the beginning of reionization to R > 10 Mpc towards the end. We present a detailed statistical description of our results, and compare them with a numerical scheme based on the analytic model by Furlanetto, Zaldarriaga, and Hernquist. We find that the analytic calculation reproduces the size distribution of HII regions and the 21 cm power spectrum of the radiative transfer simulation remarkably well. The ionization field from the simulation, however, has more small scale structure than the analytic calculation, owing to Poisson scatter in the simulated abundance of galaxies on small scales. We propose and validate a simple scheme to incorporate this scatter into our calculations. Our results suggest that analytic calculations are sufficiently accurate to aid in predicting and interpreting the results of future 21 cm surveys. In particular, our fast numerical scheme is useful for forecasting constraints from future 21 cm surveys, and in constructing mock surveys to test data analysis procedures.

description: Brown dwarfs are substellar objects too low mass to initiate the hydrogen fusion necessary to be considered stars. Ultracool dwarfs, objects with spectral types of M7 or later, are a mix of low mass stars and brown dwarfs. We have obtained the first high-resolution (R ∼ 45, 000) H- and K-band spectral sequence of ultracool dwarfs with spectral types ranging from M1.5 V to T6, including known low-gravity objects at six spectral types (M9, L0, L1, L2, L3, L5). All spectra were obtained using the Immersion Grating INfrared Spectrometer (IGRINS) at a resolving power of R ∼ 45,000. We compared 22 of our objects to synthetic spectra created from the atmospheric models of Saumon & Marley (2008), to measure specific properties including effective temperature, cloud properties, rotational velocities, and surface gravity.

description: The effects of the Gribov copies on the gluon and ghost propagators are investigated in SU(2) Euclidean Yang-Mills theory quantized in the maximal Abelian gauge. By following Gribov's original approach, extended to the maximal Abelian gauge, we are able to show that the diagonal component of the gluon propagator displays the characteristic Gribov type behavior. The off-diagonal component is found to be of the Yukawa type, with a dynamical mass originating from the dimension two gluon condensate, which is also taken into account. Furthermore, the off-diagonal ghost propagator exhibits infrared enhancement. Finally, we make a comparison with available lattice data.

description: This paper presents a wearable electrotactile feedback system to enhance contact information for mid-air interactions with virtual objects. In particular, we propose the use of electrotactile feedback to render the interpenetration distance between the user's finger and the virtual content is touched. Our approach consists of modulating the perceived intensity (frequency and pulse width modulation) of the electrotactile stimuli according to the registered interpenetration distance. In a user study (N=21), we assessed the performance of four different interpenetration feedback approaches: electrotactile-only, visual-only, electrotactile and visual, and no interpenetration feedback. First, the results showed that contact precision and accuracy were significantly improved when using interpenetration feedback. Second, and more interestingly, there were no significant differences between visual and electrotactile feedback when the calibration was optimized and the user was familiarized with electrotactile feedback. Taken together, these results suggest that electrotactile feedback could be an efficient replacement of visual feedback for enhancing contact information in virtual reality avoiding the need of active visual focus and the rendering of additional visual artefacts.

description: Genomic studies and their use in selection programs are having a strong impact in dairy cattle selection (E. Liu et al., 2010). The first aim was to create a high resolution map of CNV regions (CNVRs) in Brown Swiss cattle and the characterization of identified CNVs as markers for quantitative and population genetic studies. CNVs were called in a set of 164 sires with PennCNV and genoCN. PennCNV identified 2,377 CNVRs comprising 1,162 and 1,131 gain and loss events, respectively, and 84 regions of complex nature. GenoCN detected 41,519 CNVRs comprising 3,475 and 34,485 gain and loss events, respectively, and 3,559 regions of complex ones. Consensus calls between algorithms were summarized to CNVRs at the population level. GenoCN was also used to identify total allelic content in consensus CNVRs. Moreover, population haplotype frequencies were calculated. Linkage disequilibrium (LD) was established between CNVs and SNPs in and around CNVRs. In this study the potential contribution of CNVs as genetic markers for genome wide association studies (GWAS) has been assessed thanks to PIC and LD values. The next aim is to investigate genomic structural variation in cattle using dense SNP information in more than 1000 samples of the Italian and Swiss Brown Swiss breed genotyped on HD Bovine BeadChips. Today there is still no CNV map available across Brown Swiss populations belonging to different countries. This study therefore expands the catalogue of CNVRs in the bovine genome, delivers an international based high-resolution map of CNVRs specific to Brown Swiss dairy cattle and will lastly provide information for GEBV estimation with CNVs.

description: Mastitis represents the most important disease of dairy cattle. Stabilized or primary epithelial cell lines have been extensively used to study the molecular mechanisms of the immune response in the udder. Both models are considered reliable, but are constituted by a single cell population, i.e. epithelial cells, and changes in cell morphology and metabolism may occur, as a result of subculture, or even genetic instability. The aim of this study was to evaluate the immune response of an ex vivo model of the mammary gland, where the three-dimensional structure is maintained, assuming that the results were more comparable to the in vivo response. Ex vivo 2 mm3 -sections of a heifer udder were cultured under standardized conditions and treated for 3, 6, and 18 h with either E. coli lipopolysaccharide (LPS) or with S. aureus lipoteichoic acid (LTA). These molecules are constituent of the cell walls of Gram-negative or -positive bacteria, respectively and are applied as an inflammatory stimulus in the research of mastitis pathogenesis. Samples were analyzed for cell proliferation and apoptosis by immunofluorescence, in order to validate the model. Thereafter, we analyzed the mRNA expression of key molecules of the innate immune response (TNFα, IL-1β, IL-6, IL-8 and LAP) by quantitative real-time PCR. We used three reference genes validated by geNorm application, as the better internal standard for mammary gland tissue. The model did not show proliferation and apoptosis increased during the culture period. The preliminary results showed diverse patterns for the different cytokines and LAP: mRNA expression was overall increased, but peaked at different time points. These data suggest that such ex vivo model could be a valid approach to study the mammary immune response to bacteria.

description: The kinetic magnetoelectric effect is an orbital analogue of the Edelstein effect and offers an additional degree of freedom to control magnetisation via the charge current. Here we theoretically propose a gigantic kinetic magnetoelectric effect in topological insulators and interpret the results in terms of topological surface currents. We construct a theory of the kinetic magnetoelectric effect for a surface Hamiltonian of a topological insulator, and show that it well describes the results by direct numerical calculation. This kinetic magnetoelectric effect depends on the details of the surface, meaning that it cannot be defined as a bulk quantity. We propose that Chern insulators and Z_2 topological insulators can be a platform with a large kinetic magnetoelectric effect, compared to metals by 5 - 8 orders of magnitude, because the current flows only along the surface. We demonstrate the presence of said effect in a topological insulator, identifying Cu$_2$ZnSnSe$_4$ as a potential candidate.

description: A transition-metal-free Iodine-K2CO3 catalyzed efficient oxidation of 4,7-dihydropyrazolo[3,4-b]pyridines has been developed for the practical synthesis of corresponding pyrazolo[3,4-b]pyridines. The method is suitable for synthesis of variously substituted pyrazolo[3,4-b]pyridines as it is free from tedious purification steps and gives pure products in high yields. Molecular iodine (I2), being inexpensive, environmentally benign, and easy‐to‐handle reagent, was used to carry out the dehydrogenation under mild reaction conditions.

description: An analytical formulation for the band structure and Bloch modes in elliptically birefringent magnetophotonic crystals is presented. The model incorporates both the effects of gyrotropy and linear birefringence generally present in magneto-optic thin film devices. Full analytical expressions are obtained for the dispersion relation and Bloch modes in a layered stack photonic crystal and their properties are analyzed. It is shown that other models recently discussed in the literature are contained as special limiting cases of the formulation presented herein.

description: Assisted by general symmetry arguments and a many-body invariant, we introduce a phase of matter that constitutes a topological SO(5) superfluid. Key to this finding is the realization of an exactly solvable model that displays some similarities with a minimal model of superfluid $^3$He. We study its quantum phase diagram and correlations, and find exotic superfluid as well as metallic phases in the repulsive sector. At the critical point separating trivial and nontrivial superfluid phases, our Hamiltonian reduces to the globally SO(5)-symmetric Gaudin model with a degenerate ground manifold that includes quartet states. Most importantly, the exact solution permits uncovering of an interesting non-pair-breaking mechanism for superfluids subject to external magnetic fields. Nonintegrable modifications of our model lead to a strong-coupling limit of our metallic phase with a ground-state manifold that shows an extensive entropy.

description: We present a detailed analysis of decoherence free subspaces and develop a rigorous theory that provides necessary and sufficient conditions for dynamically stable decoherence free subspaces. This allows us to identify a special class of decoherence free states which rely on incoherent generation of coherences. We provide examples of physical systems that support such states. Our approach employs Markovian master equations and applies primarily to finite-dimensional quantum systems.

description: Poster for the Cool stars 20.5 virtual conference. Abstract: The amount of mass lost by stars during the red-giant branch (RGB) phase is one of the main parameters to correctly study later stages of stellar evolution. In spite of its importance, a fully-comprehensive understanding of this phenomenon is still missing and we mostly rely on empirical formulations. The Galactic Globular Clusters (GCs) are ideal targets to derive such formulations of mass loss, but the presence of multiple populations has been a major challenge.
 We combine Hubble Space Telescope photometry with stellar evolutionary models, to analyse the horizontal branch (HB) stars in 53 GCs. We constrained the helium abundance for the first and the “extreme” second generations stars using independent measurements based on the RGB. With these new constrains the parameters degeneracy traditionally associated to these stars has been broken for the first time. Our main results are: the mass loss of first generation stars is tightly correlated with cluster metallicity; the location of helium enriched stars on the HB is reproduced only by adopting a higher RGB mass loss, compared to the first generation; and, finally, the difference in mass loss tightly correlates with helium enhancement and cluster mass.

rapid rotators

description: Prominences, cool condensations of coronal plasma, have been observed on many types of star. Rapidly rotating stars are known to show “slingshot prominences”, that form multiple stellar radii above the surface. Models of these features typically focus on solar type stars, especially the prototype AB Doradus. Here we model the “prominence formation sites” around a sample of rapidly rotating M-dwarfs. Using Zeeman Doppler Imaging (ZDI) maps of our stellar sample, the magnetic field structure within the corona can be constructed, assuming a potential field. We define “prominence formation sites” as locations of stable equilibrium within the constructed field topologies, which are found via modelling of the ZDI maps. We use the mass loss rates per unit area (Mdot/A) of the modelled prominences to predict this same quantity for the stellar wind, by assuming that the same mechanism of an isothermal up flow feeds both events. We find that all stars in our sample show prominence formation sites, suggesting that prominences are common features on these stars. We plot the prominence mass loss rates per unit area on Wood’s plot of (Mdot/A) versus stellar X-ray flux and find our line of best fit (Mdot/A proportional to 1.32) matches well with previously published relations. We also show that due to the inclination at which we view these stars, many prominences would not cross the stellar disc from our line of sight and therefore would not be found by observational methods, greatly underestimating the true mass loss rate.

description: The development of commercially viable fuel cells and metal‐air batteries requires effective and cheap bifunctional catalysts for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). Multi‐component Pt−Fe−Co−Ni nanoparticles on multi‐walled carbon nanotubes (MWCNTs) were synthesized by wet chemistry route via NaBH₄ reduction of metal salts, followed by sintering at different temperatures. The catalyst demonstrates an excellent ORR activity and a promising OER activity in 0.1 m KOH, with a bi‐functional over‐potential, ΔE of 0.83 V, which is comparable to the values of Pt/C or RuO₂. Furthermore, it shows outstanding long‐term stability in ORR and OER, namely diffusion limited current density at a potential of 0.3 V decreased just by 5.5 % after 10000 cycles in ORR. The results of the PFCN@NT³⁰⁰ indicate a significant effect of the substitution of Pt by the transition metal (TM) and the formation of nanoparticles on the catalytic performance, especially in the OER.
