description: The work presented here is a novel biological approach for the compliant control of a robotic arm in real time (RT). We integrate a spiking cerebellar network at the core of a feedback control loop performing torque-driven control. The spiking cerebellar controller provides torque commands allowing for accurate and coordinated arm movements. To compute these output motor commands, the spiking cerebellar controller receives the robot's sensorial signals, the robot's goal behavior, and an instructive signal. These input signals are translated into a set of evolving spiking patterns representing univocally a specific system state at every point of time. Spike-timing-dependent plasticity (STDP) is then supported, allowing for building adaptive control. The spiking cerebellar controller continuously adapts the torque commands provided to the robot from experience as STDP is deployed. Adaptive torque commands, in turn, help the spiking cerebellar controller to cope with built-in elastic elements within the robot's actuators mimicking human muscles (inherently elastic). We propose a natural integration of a bio inspired control scheme, based on the cerebellum, with a compliant robot. We prove that our compliant approach outperforms the accuracy of the default factory-installed position control in a set of tasks used for addressing cerebellar motor behavior: controlling six degrees of freedom (DoF) in smooth movements, fast ballistic movements, and unstructured scenario compliant movements.

description: Objectives To examine how work-related mobility among female sex workers (FSWs) is associated with gender-based violence (GBV) in Iringa, Tanzania. Design Cross-sectional analyses were conducted on baseline data gathered between October 2015 and April 2016 from FSWs participating in Project Shikamana, a community empowerment-based combination HIV prevention intervention. Setting Participants were recruited for the baseline study using venue-based time-location sampling in two communities in Iringa, Tanzania. Participants FSWs were eligible for participation if they were 18 years or older and had exchanged sex for money within the past month. Four-hundred ninety-six FSWs participated in the baseline survey. Primary and secondary outcome measures Any recent experience of GBV was examined by recent work-related mobility among FSWs. Any recent experience of GBV was also disaggregated by severity for analyses. All bivariate and multivariate binary and multinomial logistic regressions adjusted for intraclass correlations among women recruited from the same venues. Results Forty per cent of participants experienced recent physical or sexual violence, and 30% recently experienced severe physical or sexual violence. Thirtythree per cent of participants recently exchanged sex for money outside of their district or region, and 12% were both intraregionally and inter-regionally mobile for sex work. Intraregionally and inter-regionally mobile FSWs had 1.9 times greater odds of reporting recent GBV (adjusted OR: 1.89; 95% CI: 1.06 to 3.38; p=0.031) compared with non-mobile FSWs and a 2.5 times higher relative risk for recent experience of severe GBV relative to no recent GBV (relative risk ratio: 2.51; 95% CI: 1.33 to 4.74; p=0.005). Conclusions Mobility for sex work may increase FSWs’ exposure to GBV, particularly more severe GBV. The vulnerability of mobile FSWs to violence, particularly severe forms, demands inclusive services that are accessible to mobile FSWs.

description: We address theoretically aggregation of DNA segments by multivalent polyamines such as spermine and spermidine. In experiments, the aggregation occurs above a certain threshold concentration of multivalent ions. We demonstrate that the dependence of this threshold on the concentration of DNA has a simple form. When the DNA concentration c_DNA is smaller than the monovalent salt concentration, the threshold multivalent ion concentration depends linearly on c_DNA, having the form alpha c_DNA + beta. The coefficients alpha and beta are related to the density profile of multivalent counterions around isolated DNA chains, at the onset of their aggregation. This analysis agrees extremely well with recent detailed measurements on DNA aggregation in the presence of spermine. From the fit to the experimental data, the number of condensed multivalent counterions per DNA chain can be deduced. A few other conclusions can then be reached: i) the number of condensed spermine ions at the onset of aggregation decreases with the addition of monovalent salt; ii) the Poisson-Boltzmann theory over-estimates the number of condensed multivalent ions at high monovalent salt concentrations; iii) our analysis of the data indicates that the DNA charge is not over-compensated by spermine at the onset of aggregation.

description: Genus Paravelia Breddin, 1898
 Paravelia is currently comprised of 51 described species and its distribution extends from Mexico to Argentina (Rodrigues et al., 2014b; Aristizábal-García et al., 2015; Rodrigues & Moreira, 2016b, c; Polhemus et al., 2019). The species can be collected in a great variety of environments such as emergent vegetation of streams and lakes, temporary pools, in the tanks of bromeliads, and subterranean waters in caves. The taxonomy of the genus has been examined in the recent years, with articles aimed at redescribing and photographing known species, as well as describing new species (e.g., Polhemus, 2014; Rodrigues et al., 2014b; Rodrigues & Moreira, 2016b, c; Polhemus et al., 2019). In general, in the field it is common to collect only one or a few specimens of Paravelia species. Two recently described species from Brazil are examples of the type series composed only by the holotype: P. cunhai and P. polhemusi.

description: Lecithin:cholesterol acyltransferase (LCAT) catalyzes plasma cholesteryl ester formation and is defective in familial lecithin: cholesterol acyltransferase deficiency (FLD), an autosomal recessive disorder characterized by low high-density lipoprotein, anemia, and renal disease. This study aimed to investigate the mechanism by which compound A [3-(5-(ethylthio)-1,3,4-thiadiazol- 2-ylthio)pyrazine-2-carbonitrile], a small heterocyclic amine, activates LCAT. The effect of compound A on LCAT was tested in human plasma andwith recombinant LCAT.Mass spectrometry and nuclear magnetic resonance were used to determine compound A adduct formation with LCAT. Molecular modeling was performed to gain insight into the effects of compound A on LCAT structure and activity. Compound A increased LCAT activity in a subset (three of nine) of LCATmutations to levels comparable to FLD heterozygotes. The site-directed mutation LCAT-Cys31Gly prevented activation by compound A. Substitution of Cys31 with charged residues (Glu, Arg, and Lys) decreased LCAT activity, whereas bulky hydrophobic groups (Trp, Leu, Phe, and Met) increased activity up to 3-fold (P, 0.005).Mass spectrometry of a tryptic digestion of LCAT incubated with compound A revealed a 1103.017 m/z adduct on Cys31, consistent with the addition of a single hydrophobic cyanopyrazine ring. Molecular modeling identified potential interactions of compound A near Cys31 and structural changes correlating with enhanced activity. Functional groups important for LCAT activation by compound A were identified by testing compound A derivatives. Finally, sulfhydryl-reactive b-lactams were developed as a new class of LCAT activators. In conclusion, compound A activates LCAT, including some FLD mutations, by forming a hydrophobic adduct with Cys31, thus providing a mechanistic rationale for the design of future LCAT activators.

description: We introduce the Friedrichs model at finite temperature which is one- and zero-particle restriction of spin-boson in the rotating wave approximation and obtain the population of the excited state for this model. We also consider the oscillator interacting with bosonic thermal bath in the rotating wave approximation and obtain dynamics of mean excitation number for this oscillator. Both solutions are expressed in terms of integrals of zero-temperature solutions with correspondent correlation functions.

description: We report on a new measurement of the beam transverse single spin asymmetry in electron-proton elastic scattering, $A^{ep}_{\perp}$, at five beam energies from 315.1 MeV to 1508.4 MeV and at a scattering angle of $30^{\circ} < θ< 40^{\circ}$. The covered $Q^2$ values are 0.032, 0.057, 0.082, 0.218, 0.613 (GeV/c)$^2$. The measurement clearly indicates significant inelastic contributions to the two-photon-exchange (TPE) amplitude in the low-$Q^2$ kinematic region. No theoretical calculation is able to reproduce our result. Comparison with a calculation based on unitarity, which only takes into account elastic and $\mathrm{πN}$ inelastic intermediate states, suggests that there are other inelastic intermediate states such as $\mathrm{ππN}$, $\mathrm{K Λ}$ and $\mathrm{ηN}$. Covering a wide energy range, our new high-precision data provide a benchmark to study those intermediate states.

description: Protein reference database (DIAMOND formatted) used for the detection of contaminant- and HGT-derived sequences in genome assemblies of arthropods (1st step of the pipeline). For more details on the construction and use of this database (and the corresponding detection pipeline), see Francois et al. 2020 G3 (https://doi.org/10.1534/g3.119.400758). Briefly: this custom protein reference database was built to cover all domains of life and included 937 species (4,622,809 sequences). The proteomes of 100 eukaryotic species were retrieved from Ensembl (Release 90; Zerbino
 et al. 2017) and Ensembl Metazoa (Release 37; Kersey et al. 2017). These included 40 metazoa (of which 20 arthropods), 20 fungi (of which 10 fungi known to infect arthropods), 20 Viridiplantae and 20 ’protists’. The proteomes of 837 prokaryotic species, of which 748 eubacteria and 89 archae, were retrieved from the Microbial Genome Database for Comparative Analysis (mbgd_2016-01; Uchiyama et al. 2014) selecting one species per genus. An additional 11 known symbionts of arthropods were subsequently included. Within each proteome, redundant sequences (.90% identity) were removed using CD-HIT (Fu et al. 2012).

description: We studied three-particle Fock state contributions to heavy-to-light form factors in the context of soft-collinear effective theory and found that they enter at leading power. These contributions are non-factorizable due to the appearance of endpoint singularities, however they do not violate spin-symmetry relations at leading power. In this talk I present their numerical estimation in a crude model in which the "soft overlap" contribution is cut off and find that they might lower the standard values for the form factors at maximum recoil significantly. Furthermore I briefly discuss the role of soft-collinear messenger modes in the region of soft overlap.

description: Astrophysical systems will never be in a real Thermodynamic equilibrium: they undergo an evaporation process due to the fact that the gravity is not able to confine the particles. Ordinarily, this difficulty is overcome by enclosing the system in a rigid container which avoids the evaporation. We proposed an energetic prescription which is able to confine the particles, leading in this way to an alternative version of the Antonov isothermal model which unifies the well-known isothermal and polytropic profiles. Besides of the main features of the isothermal sphere model: the existence of the gravitational collapse and the energetic region with a negative specific heat, this alternative model has the advantage that the system size naturally appears as a consequence of the particles evaporation.

description: In this work we determine the parameters of spiral structure for a sample of face-on spiral galaxies. In practice, the solution of this problem is a hard task because of the diversity of the observed characteristics of spiral structure, such as the arm number, their shape, arm contrast etc. In this work we study spiral structure in galaxies based on an analysis of photometric cuts perpendicular to the arm direction. The method is based on an approximation of these slices with an analytical function and derivation of the parameters of spiral structure (arm width, asymmetry, pitch angle) using the fitted parameters of this approximation. The algorithm has been applied to a sample of 155 galaxies selected from the Sloan Digital Sky Survey in different passbands. In this paper we only consider the results on the arm width: most spirals show an increase of their width with galactocentric distance. Only 14 per cent of galaxies in our sample show an opposite trend or have an almost constant arm width at all radii.

Stationary shear flows of dense granular materials : a tentative continuum modelling

description: We propose a simple continuum model to interpret the shearing motion of dense, dry and cohesion-less granular media. Compressibility, dilatancy and Coulomb-like friction are the three basic ingredients. The granular stress is split into a rate-dependent part representing the rebound-less impacts between grains and a rate-independent part associated with long-lived contacts. Because we consider stationary flows only, the grain compaction and the grain velocity are the two main variables. The predicted velocity and compaction profiles are in apparent agreement with the experimental or numerical results concerning free-surface shear flows as well as confined shear flows

description: We embed a spiking cerebellar model within an adaptive real-time (RT) control loop that is able to operate a real robotic body (iCub) when performing different vestibulo-ocular reflex (VOR) tasks. The spiking neural network computation, including event- and time-driven neural dynamics, neural activity, and spike-timing dependent plasticity (STDP) mechanisms, leads to a nondeterministic computation time caused by the neural activity volleys encountered during cerebellar simulation. This nondeterministic computation time motivates the integration of an RT supervisor module that is able to ensure a well-orchestrated neural computation time and robot operation. Actually, our neurorobotic experimental setup (VOR) benefits from the biological sensory motor delay between the cerebellum and the body to buffer the computational overloads as well as providing flexibility in adjusting the neural computation time and RT operation. The RT supervisor module provides for incremental countermeasures that dynamically slow down or speed up the cerebellar simulation by either halting the simulation or disabling certain neural computation features (i.e., STDP mechanisms, spike propagation, and neural updates) to cope with the RT constraints imposed by the real robot operation. This neurorobotic experimental setup is applied to different horizontal and vertical VOR adaptive tasks that are widely used by the neuroscientific community to address cerebellar functioning. We aim to elucidate the manner in which the combination of the cerebellar neural substrate and the distributed plasticity shapes the cerebellar neural activity to mediate motor adaptation. This paper underlies the need for a two-stage learning process to facilitate VOR acquisition.

description: Using Hubbard-Stratonovich transformation and drone-fermion representations for spin-1/2 and for spin-3/2, which is presented for the first time, we make a path-integral formulation of the Kondo lattice model. In the case of weak coupling and low temperature, the functional integral over conduction fermions can be approximated to the quadratic order and this gives the well-known RKKY interaction. In the case of strong coupling, the same quadratic approximation leads to an effective local spin-spin interaction linear in hopping energy $t$

description: In this article, we present a detailed analysis of the statistical properties of seeing for the Muztagh-ata site which is the candidate site for hosting future Chinese Large Optical/infrared Telescope (LOT) project. The measurement was obtained with Differential Image Motion Monitor (DIMM) from April 2017 to November 2018 at different heights during different periods. The median seeing at 11 meters and 6 meters are very close but different significantly from that on the ground. We mainly analyzed the seeing at 11 meters monthly and hourly, having found that the best season for observing was from late autumn to early winter and seeing tended to improve during the night only in autumn. The analysis of the dependence on temperature inversion, wind speed, direction also was made and the best meteorological conditions for seeing is given.

description: As one of the oldest systems for certifying sustainable production practices, the Forest Stewardship Council (FSC) can offer important lessons about this approach to conservation. In particular, the nearly 25 year history of FSC makes it possible to evaluate how the impacts of certification evolve over time. We estimate causal effects on deforestation from the year of certification to 2012 in ten certified tropical forest management units (FMUs) in Brazil, Gabon, and Indonesia. In the process, we demonstrate the use of open-access pan-tropical datasets and the synthetic control method (SCM) to evaluate impacts on land use and land cover change. Across the ten FMUs, our point estimates suggest that certification reduces deforestation in most years, but placebo tests show that the estimated effects are generally not significantly different from zero. In the three FMUs for which SCM is most plausible (because the synthetic controls are good matches for the certified FMUs in the pre-certification period), we find that certification reduces deforestation in the year immediately after certification and in the most recent year in our dataset (2012), with statistically significant effects on the FMUs in Brazil and Indonesia. However, looking across all years and FMUs, results are more variable. One possible reason is that our measure of “deforestation” captures a range of disturbances that result in tree cover loss. In Brazil, we test a spatial filtering method for separating small patches that may be related to logging from large patches that more likely represent conversion to agriculture. We find that FSC certification of a FMU reduces small-scale loss of tree cover in the FMU in all years since certification, which is consistent with adoption of the reduced impact logging practices required by FSC.

The effect of sample size on field dependence of Jc for MgB2 superconductor

description: A strong effect of sample size on magnetic Jc(H) was observed for bulk MgB2 when Jc is obtained directly from the critical state model. Thus obtained zero-field Jc (Jc0) decreases strongly with the sample size, attaining a constant value for the samples larger than a few millimetres. On the other hand, the irreversibility field (Hirr) defined at Jc = 100 A/cm2 increases with the sample size. The decrease of Jc0 is described in terms of voids in the bulk MgB2 samples and superconducting screening around the cells of superconducting material between these voids (35 micro-m), because of concentration of the current in the narrow bridges connecting the cells. For samples larger than a few millimetres, the value of magnetic Jc is in agreement with the transport Jc and it is restricted by the voids. The critical state model is not suitable for obtaining Jc for small bulk MgB2. The increase of Hirr with the sample size is an artefact of defining Hirr by the value of Jc at which an additional superconducting screening on 1mm scale dominates Dm.

Η λέξη κλειδί, ώστε να μπορέσει να ανταπεξέλθει ένας σύγχρονος οργανισμός σε αυτό τον καταιγισμό εξελίξεων και στη διαχείριση κρίσεων είναι η ηγεσία. Για να χαρακτηριστεί μία ηγετική συμπεριφορά ως αποτελεσματική, απαιτείται ένας συνδυασμός ρολών ηγεσίας, ο οποίος με τον κατάλληλο τρόπο θα καταφέρει να επιτύχει βραχυπρόθεσμα αποτελέσματα, σε μία παράλληλη προσπάθεια διαμόρφωσης του μέλλοντος του οργανισμού. Η διαχείριση των κρίσεων απαιτούν συστηματική λήψη αποφάσεων, σε συνδυασμό με τη σύνθεση της απαραίτητης σύνθεσης ατόμων, η οποία θα κληθεί να εφαρμόσει αυτές τις αποφάσεις, προκειμένου να επιτευχθούν θετικά αποτελέσματα στο συντομότερο δυνατό χρονικό διάστημα. Καίρια λειτουργία του προγραμματισμού συνιστά η λήψη αποφάσεων, ως η ενέργεια εκλογής ανάμεσα σε εναλλακτικές ενέργειες, δράσεις μέσω των οποίων η ηγεσία αντιμετωπίζει επιχειρησιακά ζητήματα. Οι κάθε είδους καταστροφές ανέκαθεν ανησυχούσαν το ανθρώπινο είδος, με την παγκόσμια διάστασή τους να απαιτεί πολιτικές σε επίπεδο εθνικό, ευρωπαϊκό και διεθνές. Η αξιολόγηση του κινδύνου αποτελεί στρατηγικής σημασίας αναγκαιότητα, καθώς με αυτή τη διαδικασία, συγκρίνονται οι εκτιμώμενοι κίνδυνοι κατά των επικίνδυνων στοιχείων, τα οποία έχει προκαθορίσει ο οργανισμός.

Με την εμφάνιση των προϊόντων “light” έχει προκύψει και ένα μεγάλο διατροφικό ζήτημα: οι θετικές και οι αρνητικές τους επιδράσεις στην υγεία του ανθρώπου. Η επιστήμη της διατροφής έχει στραφεί στην αναζήτηση διαφόρων ουσιών, που να μην επηρεάζουν τα επίπεδα γλυκόζης και ινσουλίνης στο αίμα ή να μην αποδίδουν ενέργεια, ώστε να μπορούν να ικανοποιήσουν όλες τις ομάδες των καταναλωτών, όπως π.χ. διαβητικοί, παχύσαρκοι, χορτοφάγοι. Αντικείμενο αυτής της πτυχιακής είναι η σύγκριση προϊόντων salad dressings και άρτων σε σχέση με τις υγιεινές εκδοχές τους που διατίθενται στην ελληνική αγορά.

Stellar characterization of very late-type M dwarfs
Creators: name: Marfil, Emilio
Publisher: name: Zenodo
Year: 2024

description: Accurate parameter determinations (effective temperature, surface gravity, and metallicity) from stellar spectra in very cool M dwarfs (M7.0 V and beyond) still prove extremely elusive, mostly due to the absence of useful line indicators used in early M dwarfs (e.g. Fe I, Ti I lines) and the impact of stronger molecular absorption bands (TiO, VO) that severely disrupt their spectra. Additionally, the presence of more intense magnetic fields and violent activity phenomena make such determinations even more challenging. However, these accurate parameter determinations are still essential to better characterize the exoplanetary systems (i.e. habitability zone and the constraints on exoplanetary mass, radius, and composition) discovered around very cool M dwarfs: for instance, the M8.0 V exoplanet host star TRAPPIST-1 or the M7.0 V host Teegarden's Star.

In this contribution, we aim to expand the methodology used by Marfil et al. (2021), based on spectral synthesis, to characterize the coolest M dwarfs observed with CARMENES. To do so, we delve into the selection of the most reliable spectral indicators for stellar parameter determinations in a collection of very high-resolution (R = 90,000), high signal-to-noise spectra in the optical and near-infrared wavelength regions (520-1710 nm). With this goal in mind, we employed a new grid of atmospheric models called NewEra (Hauschildt et al. in prep.), which introduces significant improvements to previous grids (e.g. PHOENIX-ACES, BT-Settl, MARCS), such as updated molecular line lists. To validate such analysis, we compared the results obtained with the analysis done by Marfil et al. (2021) for the CARMENES M-dwarf GTO sample up to M7.0 V.

Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: FOS: Physical sciences

description: We present a scaling study of the QCD spectrum using a smeared P4 staggered fermion formulation, in which three, five, and seven-link staples are added to reduce the effects of flavor symmetry breaking. These studies are performed on quenched lattices generated using the one-loop improved Symanzik gauge action, with Beta=10/g^2=7.40,7.75,8.00. The corresponding lattice spacings are a = .31 fm, .21 fm, and .14 fm. Particularly, we study the O(a^2) flavor symmetry violations in the pion spectrum as well as the scaling dependence of m_rho, measured in physical units, on lattice spacing. These results are compared against previous results for the Asqtad action.
