description: There is a need for empirically based educational practices shown to support learning, yet validation tends to require a high degree of experimental control that can limit ecological validity and translation to classrooms. We describe our iterative intervention design to support preschoolers’ vocabulary through book reading coupled with playful learning, including the process of translating research-based methods to an authentic teacher-delivered intervention. Effectiveness of the teacher-implemented intervention was examined by comparing book reading alone versus book reading plus play in supporting vocabulary development in preschoolers (N = 227) from low-income families with diverse backgrounds. Teachers used definitions, gestures, and pictures to teach vocabulary. During play, teachers led play with story-related figurines while using target vocabulary. Ten teachers read books and engaged children in play (read + play [R + P]), and 6 used only book reading (read-only [RO]). For children in both the R + P and RO conditions, within-subjects analyses of gains on taught versus control words revealed large effects on receptive (R + P, d = 1.08; RO, d = 0.92) and expressive vocabulary (R + P, d = 1.41; RO, d =1.23). Read-only had a statistically significant effect (d = 0.20) on a standardized measure of receptive vocabulary, but there were no statistically significant differences between conditions. Moderate to large effects were found using an expressive task when words were tested 4 months after they were taught. Implications for curriculum design and the potential benefits of enhancing children’s vocabulary through book reading and playful learning are discussed.

description: In this work, a new algorithm is proposed to compute single particle (infinite dilution) thermodiffusion using Non-Equilibrium Molecular Dynamics simulations through the estimation of the thermophoretic force that applies on a solute particle. This scheme is shown to provide consistent results for simple Lennard-Jones fluids and for model nanofluids (spherical non-metallic nanoparticles + Lennard-Jones fluid) where it appears that thermodiffusion amplitude, as well as thermal conductivity, decrease with nanoparticles concentration. Then, in nanofluids in the liquid state, by changing the nature of the nanoparticle (size, mass and internal stiffness) and of the solvent (quality and viscosity) various trends are exhibited. In all cases the single particle thermodiffusion is positive, i.e. the nanoparticle tends to migrate toward the cold area. The single particle thermal diffusion 2 coefficient is shown to be independent of the size of the nanoparticle (diameter of 0.8 to 4 nm), whereas it increases with the quality of the solvent and is inversely proportional to the viscosity of the fluid. In addition, this coefficient is shown to be independent of the mass of the nanoparticle and to increase with the stiffness of the nanoparticle internal bonds. Besides, for these configurations, the mass diffusion coefficient behavior appears to be consistent with a Stokes-Einstein like law.

description: Since the mass of the electron is very small relative to atomic masses, Thomson scattering of low-energy photons ($hν\ll m_ec^2$) produces thermal Doppler frequency shifts that are much larger than atomic Doppler widths. A method is developed here to evaluate the electron scattering emissivity from a given radiation field which is considerably faster than previous methods based on straightforward evaluation of the scattering integral. This procedure is implemented in our multilevel radiative code (MALI), which now takes full account of the effects of noncoherent electron scattering on level populations, as well as on the emergent spectrum. Calculations using model atmospheres of hot, low-gravity stars display not only the expected broad wings of strong emission lines but also effects arising from the scattering of photons across continuum edges. In extreme cases this leads to significant shifts of the ionization equilibrium of helium.

description: Additional file 5. Dye-binding assay and epitope mapping of αSyn_RT-QuIC products generated by MSA-P (n = 20) and MSA-C (n = 10) samples at ITA-lab. Thirty-five μL of αSyn_RT-QuIC products, generated without the use of ThT, were incubated with three different fluorescent dyes: (i) ThT [10 μM], (ii) Congo Red [5 μM] and (iii) Amytracker 630 (purchased from Ebba Biotech and diluted 1:800) for 30 min in the dark at room temperature. Fluorescent signals were measured with the appropriate wave-lengths (448 exc/482 emi for ThT, 544 exc/620 emi for Congo red and 510 exc/635 emi for Amytracker 630) using the BMG LabTech CLARIOSTAR microplate reader. Regardless of the probe used, all MSA-P samples (except for MSA-P_10 and MSA-P_11) showed strong fluorescent signals while the MSA-C did not. These differences were statistically significant in the case of (i) ThT (t-test p = 0.0063), (ii) Congo red (t-test, p = 0.0018) and (iii) Amytracker 630 (t-test, p = 0.0051). Graphs show the mean values (± SEM) of MSA-P and MSA-C fluorescent signals obtained from (i) ThT (graph on the left), (ii) Congo red (graph in the middle) and (iii) Amytracker 630 (graph on the right) analysis (a). Eight μL of αSyn_RT-QuIC products generated by MSA-P and MSA-C samples were treated with PK [2.5 mg/mL] for 1 h at 37 °C under shaking (500 rpm) and immunoblotted with antibodies directed against three different epitopes of α-synuclein: (i) clone 5C2 (epitopes 61–95, Novus Biologicals), (ii) AB5038 (epitopes 111–131, Chemicon international), and (iii) clone 42 (epitopes 15–123, BD Bioscience). No signals were observed in samples immunoblotted with the AB5038 and the clone 5C2, while with the clone 42, PK resistant bands were specifically detected in αSyn_RT-QuIC products seeded with MSA-P but not in those seeded with MSA-C samples (b).

description: Transition metal dichalcogenide (TMD) alloys have attracted great interests in recent years due to their tunable electronic properties, especially the semiconductor-metal phase transition, along with their potential applications in solid-state memories and thermoelectrics. However, the thermal conductivity of layered two-dimensional (2D) TMD alloys remains largely unexplored despite that it plays a critical role in the reliability and functionality of TMD-enabled devices. In this work, we study the temperature-dependent anisotropic thermal conductivity of the phase-transition 2D TMD alloys WSe2(1-x)Te2x in both the in-plane direction (parallel to the basal planes) and the cross-plane direction (along the c-axis) using time-domain thermoreflectance measurements. In the WSe2(1-x)Te2x alloys, the cross-plane thermal conductivity is observed to be dependent on the heating frequency (modulation frequency of the pump laser) due to the non-equilibrium transport between different phonon modes. Using a two-channel heat conduction model, we extracted the anisotropic thermal conductivity at the equilibrium limit. A clear discontinuity in both the cross-plane and the in-plane thermal conductivity is observed as x increases from 0.4 to 0.6 due to the phase transition from the 2H to Td phase in the layered 2D alloys. The temperature dependence of thermal conductivity for the TMD alloys was found to become weaker compared with the pristine 2H WSe2 and Td WTe2 due to the atomic disorder. This work serves as an important starting point for exploring phonon transport in layered 2D alloys.

description: We consider the simplicial state-sum model of Ponzano and Regge as a path integral for quantum gravity in three dimensions. We examine the Lorentzian geometry of a single 3-simplex and of a simplicial manifold, and interpret an asymptotic formula for $6j$-symbols in terms of this geometry. This extends Ponzano and Regge's similar interpretation for Euclidean geometry. We give a geometric interpretation of the stationary points of this state-sum, by showing that, at these points, the simplicial manifold may be mapped locally into flat Lorentzian or Euclidean space. This lends weight to the interpretation of the state-sum as a path integral, which has solutions corresponding to both Lorentzian and Euclidean gravity in three dimensions.

description: We derive the equations of motion for general strings, i.e. strings with arbitrary relation between tension $τ$ and energy per unit length $ε$. The renormalization of $τ$ and $ε$ that results from averaging out small scale wiggles on the string is obtained in the general case to lowest order in the amount of wiggliness. For Nambu-Goto strings we find deviations from the equation of state $ετ= {\rm constant}$ in higher orders. Finally we argue that wiggliness may radically modify the gauge cosmic string scenario.

description: We study the effect of introducing altruistic agents in a Schelling-like model of residential segregation. We find that even an infinitesimal proportion of altruists has dramatic catalytic effects on the collective utility of the system. Altruists provide pathways that move the system away from the suboptimal equilibrium it would reach if the system included only egoist agents, allowing it to reach the optimal steady state.

description: The masses distribution inside the Earth governs the behaviour of the rotation axis in the Earth (polar motion), as well as the Earth rotation rate (or equivalently, length of day). This masses distribution can be measured from space owing to artificial satellites, the orbitography of which provides the Earth gravity field determination. Then, the temporal variations of the Earth gravity field can be related to the variations of the Earth Orientation Parameters (EOP) (with the Inertia Tensor). Nowadays, owing to the satellite laser ranging (SLR) technique and to the new gravimetric satellite missions (such as CHAMP or GRACE), the temporal variations of the low degree coefficients of the Earth gravity field (i.e. Stokes coefficients) can be determined. This paper is one of the first study using gravity variations data in the equations already established (e.g. Lambeck 1988) and linking the variations of the length of day and of the C20 Stokes coefficient (or, linking the polar motion and the C21 and S21 coefficients). This paper combines the Earth rotation data (mainly obtained from VLBI and GPS measurements) and the Earth gravity field variations ones (e.g. Lageos I and II data, or GRACE data), in order to complete and constrain the models of the Earth rotation. The final goal is a better Earth global dynamics understanding, which possible application can be the constraint on the couplings into the Earth system (e.g. core-mantle couplings).

description: Elyonurus muticus (Em) is a discarded native grass from South America, and its essential oil recently demonstrated properties comparable to Cymbopogon flexuosus (Cf) and Cymbopogon citratus (Cc) essential oils. Thus, this study aimed to compare these lemongrass essential oils regarding their potential as food preservatives. Chemical composition (GC/MS), antioxidant, Fe2+ chelatiion, antibacterial activity and phenolic content were done. As for the Fe2+ chelating activity, Em essential oil had IC50 of 0.005 mg. mL−1, three and six times less than Cf and Cc, respectively. The antibacterial test exhibited major activity on Listeria monocytogenes with 54.21% inhibition effect to Em oil (concentration 1:2). Em and Cf oily solutions 0.750 µL.L−1 indicated high postharvest preserving capacity, as they kept phenolic content of strawberries during 15 days with less fungal development. The study emphasized Elyonurus muticus essential oil as suitable alternative to lemongrass species, for food preservation, suggesting pharmaceutical and medical applications.

description: We report the synthesis and characterization of graphite (C) doped MgB2-xCx (x = 0.0, 0.1, 0.2 and 0.3) samples. The crystal structure and microstructural characterization have been investigated by x-ray diffractometer and transmission electron microscopic (TEM) analysis. The superconducting properties especially Jc and Hc2 have been measured by employing physical property measurement system. We found that the graphite doping affects the lattice parameters as well as the microstructure of MgB2 superconductor. In case of optimally doped (x=0.1) sample, the critical current density at 5K corresponds to 1.1 x 10^6 and 5.3 x 10^4 A/cm^2 for 3T and 5T fields respectively. The upper critical field has been enhanced nearly two times after doping. The flux pinning behavior has been investigated by flux pinning force density curve and it reveals that the flux pinning behaviour has improved significantly by doping. TEM micrographs show the graphite nanoparticles of size ~5-10 nm which are invariably present in MgB2 grains. These nanoparticles act as flux pinning centre and are responsible for enhancement of superconducting properties of MgB2.

description: I discuss and extend several results concerning the cancellation of discrete gauge anomalies. I show how heavy fermions do not decouple in the presence of discrete gauge anomalies. As a consequence, in general, cancellation of discrete gauge anomalies cannot be described merely in terms of low energy operators involving only the light fermions. I also discuss cancellation of discrete gauge anomalies through a discrete version of the Green-Schwarz (GS) mechanism as well as the possibility of discrete gauge R-symmetries and their anomalies. Finally, some phenomenological applications are discussed. This includes symmetries guaranteeing absence of FCNC in two-Higgs models and generalized matter parities stabilizing the proton in the supersymmetric standard model. In the presence of a discrete GS mechanism or/and gauge R-symmetries, new possibilities for anomaly free such symmetries are found.

description: The objective of the present study was to characterize the essential oil of Myrciaria tenella (MTEO) leaves, to determine the effects of distillation time (1 to 5 h), and to evaluate its action on acute pain and inflammation both in vivo and in vitro. MTEO was obtained by hydrodistillation for 4 h and 36 compounds were detected, mainly consisting of hydrocarbon terpenes such as β-pinene (21.46%), α-pinene (19.43%), E-caryophyllene (10.89%) and aromadendrene (9.17%). A high yield of α-pinene/β-pinene-rich MTEO was obtained after only 2 h of extraction. For in vivo biological assays, MTEO was administered to male Swiss mice, showing an action against hypernociception (acetic acid-induced abdominal writhing, formalin and Von Frey models) and inhibiting carrageenan-induced paw edema. Production of IL-6, TNF-α, IL-1β, PGE2 was reduced and production of IL-10 was increased, with no change in motor performance. MTEO also reduced cell production of NO and cytokines, in addition to inhibiting COX activity.

description: We study relativistic stars in degenerate higher-order scalar-tensor theories that evade the constraint on the speed of gravitational waves imposed by GW170817. It is shown that the exterior metric is given by the usual Schwarzschild solution if the lower order Horndeski terms are ignored in the Lagrangian and a shift symmetry is assumed. However, this class of theories exhibits partial breaking of Vainshtein screening in the stellar interior and thus modifies the structure of a star. Employing a simple concrete model, we show that for high-density stars the mass-radius relation is altered significantly even if the parameters are chosen so that only a tiny correction is expected in the Newtonian regime. We also find that, depending on the parameters, there is a maximum central density above which solutions cease to exist.

The absolute number of mRNA molecules of OPN-a predominated in normal skin and nonmelanoma skin cancer compared to OPN-b, OPN-c, and OPN-5. However, mRNAs of OPN-a, OPN-b, and OPN-c were expressed in higher levels in cutaneous squamous cell carcinomas (cSCCs) and basal cell carcinomas relative to normal skin. Additionally, OPN-5 expression was higher than OPN-b and OPN-c, and OPN-c, in normal skin and nonmelanoma skin cancer, respectively. Furthermore, we identified four OPN-5 splice variants, which were cloned and analyzed for protein expression.

description: Bone metabolism constitutes the intricate processes of matrix deposition, mineralization, and resorption. Any imbalance in these processes leads to traumatic bone injuries and serious disease conditions. Therefore, bone remodeling plays a crucial role during the regeneration process maintaining the balance between osteoblastogenesis and osteoclastogenesis. Currently, numerous phytobiologics are emerging as the new therapeutics for the treatment of bone-related complications overcoming the synthetic drug-based side effects. They can either target osteoblasts, osteoclasts, or both through different mechanistic pathways for maintaining the bone remodeling process. Although phytobiologics have been widely used since tradition for the treatment of bone fractures recently, the research is accentuated toward the development of osteogenic phytobioactives, constituent-based drug designing models, and efficacious delivery of the phytobioactives. To achieve this, different plant extracts and successful isolation of their phytoconstituents are critical for osteogenic research. Hence, this review emphasizes the phytobioactives based research specifically enlisting the plants and their constituents used so far as bone therapeutics, their respective isolation procedures, and nanotechnological interventions in bone research. Also, the review enlists the vast array of folklore plants and the newly emerging nano-delivery systems in treating bone injuries as the future scope of research in the phytomedicinal orthopedic applications.
Earth rotation and variations of the gravity field, in the framework of the "Descartes-nutation" project

description: The "Descartes-Nutation" Project is devoted to the "understanding of the next decimal of precession-nutation, from the theoretical point of view as well as from the observational point of view". In this framework, we made a proposal in order to contribute to the study of (i) the dynamical flattening of the Earth, (ii) the coupling effects of the lunisolar forcing, (iii) the effect of the geophysical fluids on the EOP and (iv) the Nutation observations. We investigate further the links between Earth Orientation and Gravity Field Variations. Indeed, the masses distributions inside the Earth govern the behaviour of the rotation axis in space (precession-nutation) and in the Earth (polar motion), as well as the Earth rotation rate (or equivalently, length of the day). These distributions of masses can be measured by space owing to artificial satellites, the orbitography of which provides the Earth gravity field determination. Then, the temporal variations of the Earth gravity field can be related to the variations of the Earth Orientation Parameters (EOP) (with the Inertia Tensor). Nowadays, the Earth orientation measurements in space, obtained with Very Long Baseline Interferometry (VLBI), have a precision better than the milliarcsecond level. It is then necessary to consider all the geophysical sources that can improve the models precision. The goal of my PhD Thesis was to use the Earth gravity field measurements, as well as its variations, as a tool to improve the Earth orientation modelisation. We present here the results obtained as well as various proposals to extend these investigations (numerical studies, the use of J2 geophysical series, integration of GRACE data ...).

description: Whitefly (Bemisia tabaci) is a notorious insect pest of many economic important crop plants including cotton, tomato, etc. The main objective of the study was to evaluate the efficacy of new biological control agent to replace toxic chemical pesticides from agro-ecosystem. Clonostachys rosea associated with whitefly and aphid (Aphis gossypii) on cotton plants was isolated and characterised on a morphological and molecular basis. Phylogenetic analysis was also performed based on the internal transcribed spacer (ITS) region. Pathogenicity of C. rosea was evaluated in two concentrations against fourth instar nymphal and adult stages of B. tabaci. The study revealed that C. rosea was highly parasitic against fourth instar nymphs than adults at different spore concentrations. Two isolates of C. rosea were identified in this study, and both were morphologically similar. However, differences were observed in the ITS region of the C. rosea isolates. Our results showed that C. rosea has the prospects to serve as a potential biocontrol agent against economically important insect pests.

description: Older males often perform poorly under post-copulatory sexual selection. It is unclear, however, whether reproductive senescence is due to male age itself or the accumulated costs of the higher lifetime mating effort that is usually associated with male age. To date, very few studies have accounted for mating history and sperm storage when testing the effect of male age on sperm traits, and none test how age and past mating history influence paternity success under sperm competition. Here, we experimentally manipulate male mating history to tease apart its effects from that of age on ejaculate traits and paternity in the mosquitofish, Gambusia holbrooki. We found that old, naive males had more sperm than old, experienced males, while the reverse was true for young males. By contrast, neither male age nor mating history affected sperm velocity. Finally, using artificial insemination to experimentally control the number of sperm per male, we found that old males sired significantly more offspring than young males independently of their mating history. Our results highlight that the general pattern of male reproductive senescence described in many taxa may often be affected by two naturally confounding factors, male mating history and sperm age, rather than male age itself.

description: We consider the process containing two quark lines and an arbitrary number of gluons in a spinor helicity framework. A current with two off-shell gluons appears in the amplitude. We first study this modified gluon current using recursion relations. The recursion relation for the modified gluon current is solved for the case of like-helicity gluons. We apply the modified gluon current to compute the amplitude for $q \bar q \rightarrow q \bar q gg \cdots g$ in the like-helicity gluon case.

description: We study spin control for an electron confined in a flake of silicene. We find that the lowest-energy conduction-band levels are split by the diagonal intrinsic spin-orbit coupling into Kramers doublets with a definite projection of the spin on the orbital magnetic moment. We study the spin control by AC electric fields using the non-diagonal Rashba component of the spin-orbit interactions with the time-dependent atomistic tight-binding approach. The Rashba interactions in AC electric fields produce Rabi spin-flips times of the order of a nanosecond. These times can be reduced to tens of picoseconds provided that the vertical electric field is tuned to an avoided crossing open by the Rashba spin-orbit interaction. We demonstrate that the speedup of the spin transitions is possible due to the intervalley coupling induced by the armchair edge of the flake. The study is confronted with the results for circular quantum dots decoupled from the edge with well defined angular momentum and valley index.
SAMBA2018 Neural basis of somatosensory target detection

description: The scientific study of somatosensory awareness has yielded highly diverse findings with putative neural correlates ranging from local interactions within somatosensory cortices to activation of widely distributed frontoparietal networks. A potential source of these divergent results may reside in latent cognitive processes that often coincide with stimulus awareness in experimental settings. In fact, the most commonly employed experimental paradigm, the near-threshold somatosensory detection task, may conflate somatosensory awareness with processing of stimulus uncertainty, overt reports, and motor planning. To elucidate the contribution of these processes to neural activity commonly assumed to reflect somatosensory awareness, we employed a novel somatosensory detection task in combination with functional magnetic resonance imaging (fMRI). Participants received electrical target stimuli at intensities spanning the full range of their psychometric functions to vary stimulus uncertainty while maintaining spontaneous fluctuations in stimulus awareness. Instead of directly reporting target detection, participants assessed the congruence of their somatosensory percepts with simultaneously presented visual reference cues and reported a match or mismatch by making saccadic eye movements, such that target detection was decorrelated from overt reports and motor planning. Using a Bayesian analysis approach, we track the transformation from physical to perceptual stimulus representations along the somatosensory hierarchy. We show that the emergence of stimulus awareness is largely restricted to somatosensory regions, whereas activity in frontal and parietal areas is best explained by stimulus uncertainty and overt reports. Our results emphasize the role of early sensory cortex for conscious perception and dissect the contribution of the frontoparietal network to classical detection tasks.

description: We establish a condition for the perturbative stability of zero energy nodal points in the quasi-particle spectrum of superconductors in the presence of coexisting \textit{commensurate} orders. The nodes are found to be stable if the Hamiltonian is invariant under time reversal followed by a lattice translation. The principle is demonstrated with a few examples. Some experimental implications of various types of assumed order are discussed in the context of the cuprate superconductors.

description: The fluorescence detection of ultra high energy cosmic rays requires a detailed knowledge of the fluorescence light emission from nitrogen molecules over a wide range of atmospheric parameters, corresponding to altitudes typical of the cosmic ray shower development in the atmosphere. We have studied the temperature and humidity dependence of the fluorescence light spectrum excited by MeV electrons in air. Results for the 313.6 nm, 337.1 nm, 353.7 nm and 391.4 nm bands are reported in this paper. We found that the temperature and humidity dependence of the quenching process changes the fluorescence yield by a sizeable amount (up to 20%) and its effect must be included for a precise estimation of the energy of ultra high energy cosmic rays.

description: The study investigated how the introduction of nurse led admission and discharge processes could impact on the quality of service delivered in a surgical day ward. The study used an adapted qualitative outcome analysis (QOA) methodology developed by Morse, Penrod and Hupcy (2000). This complex methodology has 2 phases and 7 steps. Phase 1 included an assessment of the current service using a SWOT analysis, a process mapping exercise and a retrospective documentation evaluation. Phase 2 involved implementing changes in nursing practice and associated processes based on the outcomes from the phase 1 results. Nurse led admission and discharge processes were implemented as part of a QOA project in phase 2. This was supported by multidisciplinary developed policies and protocols. In service training and education were provided to the nursing and medical staff in advance of the project implementation. Staggered admission times for local and conscious sedation patients were also introduced in an attempt to reduce pre-operative wait times. The service was re-assessed for the impact of these initiatives using repeat process mapping and repeat documentation evaluation which included measurement of the number of patients admitted and discharged by nursing staff. The results of the study showed the success of the introduction of nurse led discharge (30/38 patients) with associated medical time savings of 2hrs and 40m. It confirmed that the standard of nursing documentation is comprehensive and consistent compared to medical documentation and this has further improved with the introduction of new nursing admission and discharge care plans. An associated link was also identified with staggered admission times and a reduction in pre-operative wait times. Finally, the QOA project laid the foundations for long term practice changes in the day ward which is supported by multidisciplinary developed policies and discharge criteria supported by best practice guidelines.

description: The phenomenon of gyroscopic precession is studied within the framework of Frenet-Serret formalism adapted to quasi-Killing trajectories. Its relation to the congruence vorticity is highlighted with particular reference to the irrotational congruence admitted by the stationary, axisymmetric spacetime. General precession formulae are obtained for circular orbits with arbitrary constant angular speeds. By successive reduction, different types of precessions are derived for the Kerr - Schwarzschild - Minkowski spacetime family. The phenomenon is studied in the case of other interesting spacetimes, such as the De Sitter and Gödel universes as well as the general stationary, cylindrical, vacuum spacetimes.

description: Using the covariant approach and conformal transformations, we present a gauge-invariant formalism for cosmological perturbations in generalized Einstein theories (GETs), including the Brans-Dicke theory, theories with a non-minimally coupled scalar field and certain curvature-squared theories. We find an enhancement in the growth rate of density perturbations in the Brans-Dicke theory, and discuss attractive features of GETs in the structure formation process.
