description: Concussion is a traumatic transient disturbance of the brain. In sport, the initial time and severity of concussion is known giving an opportunity for subsequent analysis. Variability in susceptibility and recovery between individual athletes depends, among other parameters, on genetic factors. The genes-encoding polypeptides that determine incidence, severity and prognosis for concussion are the primary candidates for genetic analysis. Genetic polymorphisms in the genes contributing to plasticity and repair (APOE), synaptic connectivity (GRIN2A), calcium influx (CACNA1E), uptake and deposit of glutamate (SLC17A7) are potential biomarkers of concussion incidence and recovery rate. With catalogued genetic variants, prospective genotyping of athletes at the beginning of their career will allow medical professionals to improve concussion management and return-to-play decisions.

A Geological and geophysical synthesis of the Svartliden Project, Sweden and its application in defining gold exploration targets.
Creators: name: Laurent, Y
Publisher: name: University Of Tasmania
Year: 2023

description: The Svartliden Project is located in north central Sweden, 7Skm west-northwest of the town of the Lycksele. The geology comprises of a Palaeoproterozoic package of intercalated turbiditic sedimentary rocks and extrusive coherent and non-coherent basaltic rocks. Gold mineralisation is associated with diopside +green amphibole +silica +arsenopyrite. Alteration is best developed along the intersection lineation between bedding and the primary cleavage. Mineralisation is concentrated in areas of low shear strain formed by the pressure shadow effect from the regional rotating syn-orogenic granitoids. Pyrrhotite is the most pervasive sulphide and is found as a primary mineral in carbonaceous sediments and as a late-stage sulphide in the \Mineralised Zone\". Pyrrhotite is responsible for the conductivity chargeability and along with magnetite the magnetic susceptibility found in the Svartliden shear zone. Ground magnetic and electromagnetic surveys were carried out over the project area. The ground magnetics does not differentiate the magnetite-bearing volcanics from the pyrrhotite-bearing carbonaceous sediments and the \"Mineralised Zone\". The ground electromagnetic survey defines high conductive zones generated by the pyrrhotitebearing sediments and the \"Mineralised Zone\" within resistive granitoids and volcanics. Downhole apparent resistivity IP and magnetic susceptibility were conducted on three drillholes along 1700mB. The magnetic susceptibility as with the ground magnetics is unable to differentiate magnetite-bearing volcanic rocks from the pyrrhotite-bearing units. Apparent resistivity has an inverse correlation with chargeability. Log transformation of the ground in-phase EM data delineates first- and second-order conductive anomalies. First-order anomalies represent the pyrrhotite-bearing carbonaceous sedimentary unit. Second-order anomalies represent the pyrrhotite-bearing \"Mineralised Zone\". Second-order anomalies calculated from in-phase EM data can be used to target areas for gold exploration at both a project and regional scale."

description: Theoretical models suggest that social networks influence the evolution of cooperation, but to date there have been few experimental studies. Observational data suggest that a wide variety of behaviors may spread in human social networks, but subjects in such studies can choose to befriend people with similar behaviors, posing difficulty for causal inference. Here, we exploit a seminal set of laboratory experiments that originally showed that voluntary costly punishment can help sustain cooperation. In these experiments, subjects were randomly assigned to a sequence of different groups in order to play a series of single-shot public goods games with strangers; this feature allowed us to draw networks of interactions to explore how cooperative and uncooperative behavior spreads from person to person to person. We show that, in both an ordinary public goods game and in a public goods game with punishment, focal individuals are influenced by fellow group members' contribution behavior in future interactions with other individuals who were not a party to the initial interaction. Furthermore, this influence persists for multiple periods and spreads up to three degrees of separation (from person to person to person to person). The results suggest that each additional contribution a subject makes to the public good in the first period is tripled over the course of the experiment by other subjects who are directly or indirectly influenced to contribute more as a consequence. These are the first results to show experimentally that cooperative behavior cascades in human social networks.

description: Für viele Mitglieder der Gruppe 47 wurde in den letzten Jahrzehnten eine mehr oder weniger gravierende Verstrickung in den Nationalsozialismus nachgewiesen. In dieser Studie wird erstmals untersucht, welche Auswirkungen diese biografischen Hintergründe auf die Literatur sowie die kollektive Identität der Gruppe 47 hatte. Untersucht werden u.a. Texte von Alfred Andersch, Hans Werner Richter, Wolfdietrich Schnurre, Luise Rinser, Günter Eich, Wolfgang Hildesheimer, Ilse Aichinger und Günter Grass. Unter Zuhilfenahme von erinnerungstheoretischen Ansätzen und der historischen Generationenforschung wird die kollektive Identität der Gruppe als engagierte Intellektuelle analysiert. Diese gründete in einer spezifisch westdeutschen Aneignung existenzialistischer Grundsätze und ging mit einem erinnerungshegemonialen Anspruch einher, der einen problematischen Umgang mit jüdischen und emigrierten Autorinnen und Autoren bewirkte. Ein Kernteil der Studie bildet eine vor diesem Hintergrund vorgenommene Relektüre von Günter Grass Erfolgsroman Die Blechtrommel.

description: © 2017 Published by the BMJ Publishing Group Limited. Introduction: Despite global progress on many measures of child health, rates of neonatal mortality remain high in the developing world. Evidence suggests that substantial improvements can be achieved with simple, low-cost interventions within family and community settings, particularly those designed to change knowledge and behaviour at the community level. Using social network analysis to identify structurally influential community members and then targeting them for intervention shows promise for the implementation of sustainable community-wide behaviour change. Methods and analysis: We will use a detailed understanding of social network structure and function to identify novel ways of targeting influential individuals to foster cascades of behavioural change at a population level. Our work will involve experimental and observational analyses. We will map face-to-face social networks of 30 000 people in 176 villages in Western Honduras, and then conduct a randomised controlled trial of a friendship-based network-targeting algorithm with a set of well-established care interventions. We will also test whether the proportion of the population targeted affects the degree to which the intervention spreads throughout the network. We will test scalable methods of network targeting that would not, in the future, require the actual mapping of social networks but would still offer the prospect of rapidly identifying influential targets for public health interventions. Ethics and dissemination: The Yale IRB and the Honduran Ministry of Health approved all data collection procedures (Protocol number 1506016012) and all participants will provide informed consent before enrolment. We will publish our findings in peer-reviewed journals as well as engage non-governmental organisations and other actors through venues for exchanging practical methods for behavioural health interventions, such as global health conferences. We will also develop a 'toolkit' for practitioners to use in network-based intervention efforts, including public release of our network mapping software.
The slope of the mass profile and the tilt of the fundamental plane in early-type galaxies

description: We present a survey, using the Chandra X-ray observatory, of the central gravitating mass profiles in a sample of 10 galaxies, groups and clusters, spanning ~2 orders of magnitude in virial mass. We find the total mass distributions from ~0.2--10Re, where Re is the optical effective radius of the central galaxy, are remarkably similar to powerlaw density profiles. The negative logarithmic slope of the mass density profiles, alpha, systematically varies with Re, from alpha=2, for systems with Re~4kpc to alpha=1.2 for systems with Re>30kpc. Departures from hydrostatic equilibrium are likely to be small and cannot easily explain this trend. We show that the conspiracy between the baryonic (Sersic) and dark matter (NFW/ Einasto) components required to maintain a powerlaw total mass distribution naturally predicts an anti-correlation between alpha and Re that is very close to what is observed. The systematic variation of alpha with Re implies a dark matter fraction within Re that varies systematically with the properties of the galaxy in such a manner as to reproduce, without fine tuning, the observed tilt of the fundamental plane. We speculate that establishing a nearly powerlaw total mass distribution is therefore a fundamental feature of galaxy formation and the primary factor which determines the tilt of the fundamental plane.

description: Autism is a complex developmental disorder that affects approximately 1 in 68 children (according to the recent survey conducted by the Centers for Disease Control and Prevention-CDC) in the U.S., and has become the fastest growing category of special education. Each student with autism comes with her or his own unique needs and an array of behaviors and habits that can be severe and which interfere with everyday tasks. Autism is associated with intellectual disability, impairments in social skills, and physical health issues such as sleep and abdominal disturbances. We have designed an Internet-of-Things (IoT) framework named WearSense that leverages the sensing capabilities of modern smartwatches to detect stereotypic behaviors in children with autism. In this work, we present a study that used the inbuilt accelerometer of a smartwatch to detect three behaviors, including hand flapping, painting, and sibbing that are commonly observed in children with autism. In this feasibility study, we recruited 14 subjects to record the accelerometer data from the smartwatch worn on the wrist. The processing part extracts 34 different features in each dimension of the three-axis accelerometer, resulting in 102 features. Using and comparing various classification techniques revealed that an ensemble of 40 decision trees has the best accuracy of around 94.6%. This accuracy shows the quality of the data collected from the smartwatch and feature extraction methods used in this study. The recognition of these behaviors by using a smartwatch would be helpful in monitoring individuals with autistic behaviors, since the smartwatch can send the data to the cloud for comprehensive analysis and also to help parents, caregivers, and clinicians make informed decisions.

description: This paper deals with the problem of detecting maritime targets embedded in nonhomogeneous sea clutter, where limited number of secondary data is available due to the heterogeneity of sea clutter. A class of linear discriminant analysis (LDA)-based matrix information geometry (MIG) detectors is proposed in the supervised scenario. As customary, Hermitian positive-definite (HPD) matrices are used to model the observational sample data, and the clutter covariance matrix of received dataset is estimated as geometric mean of the secondary HPD matrices. Given a set of training HPD matrices with class labels, that are elements of a higher-dimensional HPD matrix manifold, the LDA manifold projection learns a mapping from the higher-dimensional HPD matrix manifold to a lower-dimensional one subject to maximum discrimination. In the current study, the LDA manifold projection, with the cost function maximizing between-class distance while minimizing within-class distance, is formulated as an optimization problem in the Stiefel manifold. Four robust LDA-MIG detectors corresponding to different geometric measures are proposed. Numerical results based on both simulated radar clutter with interferences and real IPIX radar data show the advantage of the proposed LDA-MIG detectors against their counterparts without using LDA as well as the state-of-art maritime target detection methods in nonhomogeneous sea clutter.

description: © 2017 Author(s). We study the low-temperature charge transfer reaction between a neutral atom and an ion under the influence of near-resonant laser light. By setting up a multi-channel model with field-dressed states, we demonstrate that the reaction rate coefficient can be enhanced by several orders of magnitude with laser intensities of 106 W/cm2 or larger. In addition, depending on laser frequency, one can induce a significant enhancement or suppression of the charge-exchange rate coefficient. For our intensities, multi-photon processes are not important.

This review paper describes the successful searches carried out independently by the two collaborations, allowing the reader to see the similarities and differences that led to the simultaneous discoveries. Both collaborations measured a cross section sigma(ppbar->tb+X,tqb+X) consistent with the standard model prediction at 5.0 standard deviation significance, and set a lower limit on the quark mixing matrix element |V_tb| without assuming matrix unitarity with three quark generations.

Subjects: hep-lat

description: © 2017 American Physical Society. We present results on the renormalization functions of the quark field and fermion bilinears with up to one covariant derivative. For the fermion part of the action, we employ the twisted mass formulation with Nf=2 and Nf=4 degenerate dynamical quarks, while in the gluon sector, we use the Iwasaki-improved action. The simulations for Nf=4 have been performed for pion masses in the range of 390-760 MeV and at three values of the lattice spacing, a, corresponding to β=1.90, 1.95, 2.10. The Nf=2 action includes a clover term with csw=1.57551 at β=2.10, and three ensembles at different values of mπ. The evaluation of the renormalization functions is carried out in the RI′ scheme using a momentum source. The nonperturbative evaluation is complemented with a perturbative computation, which is carried out at one-loop level and to all orders in the lattice spacing, a. For each renormalization function computed nonperturbatively, we subtract the corresponding lattice artifacts to all orders in a, so that a large part of the cutoff effects is eliminated. The renormalization functions are converted to the MS scheme at a reference energy scale of μ=2 GeV after taking the chiral limit.

description: Abstract

Indonesia has a population that is quite high compared to 2007, namely 237,641,326 people in 2014 or an increase of 1.5 percent, namely from 232,900,000 people and in 2020 there were 270,203,917 people. The distribution of the female population is 133,542,018 and the male population is 136,661,899. Based on the results of population projections, in 2019 the population of North Sumatra is 14,562,549 people consisting of 7,266,207 men and 7,296,342 women or with a sex ratio of 99.59 (every 100 women there are 99 men). The aim of the study was to find out the relationship between the decision to choose contraceptive devices and socio-economic conditions on the fertility of couples of childbearing age in the working area of the Bukit Kapur Health Center in Dumai City in 2022. The research method is observational and the type of research is descriptive analytic with cross sectional, namely studying the correlation between risk factors with effects in the form of certain health status. The results of the study showed that there was a relationship between the decision to choose the type of contraception and fertility in the working area of the Bukit Kapur Health Center, Dumai City, in 2022 where the p-value was 0.003 (p <0.05) and there was no relationship between socio-economic status and fertility in the Bukit Kapur City Health Center work area. Dumai in 2022 where the p-value is 0.078 (p <0.05). Communities are able to seek information and increase knowledge about the Relationship between Contraceptive Selection Decisions

description: VBFNLO is a fully flexible parton level Monte Carlo program for the simulation of vector boson fusion, double and triple vector boson production in hadronic collisions at next-to-leading order in the strong coupling constant. VBFNLO includes Higgs and vector boson decays with full spin correlations and all off-shell effects. In addition, VBFNLO implements CP-even and CP-odd Higgs boson via gluon fusion, associated with two jets, at the leading-order one-loop level with the full top- and bottom-quark mass dependence in a generic two-Higgs-doublet model. A variety of effects arising from beyond the Standard Model physics are implemented for selected processes. This includes anomalous couplings of Higgs and vector bosons and a Warped Higgsless extra dimension model. The program offers the possibility to generate Les Houches Accord event files for all processes available at leading order.

Serum protein - bound iodine levels in growing and pregnant sheep
Creators: name: Lee, Winston Keh Chin
Publisher: name: University of British Columbia
Year: 2011

description: Changes in serum protein-bound iodine (PBI) levels were estimated in pregnant and non-pregnant mature ewes during the months from August to March. The PBI levels in ewes appeared to be elevated by low temperature (P < 0.001) and depressed by high temperature. The estrous cycle affected the PBI levels in ewes. The peak of PBI level was within 48 hours of estrus period. Breed differences played an important part on PBI levels; the Dorset breed generally had a higher PBI level than the Suffolk crossbred animal. The PBI levels in pregnant ewes became significantly higher (P < 0.05) than in the control after the third week of pregnancy. This increase in PBI level was followed by a significant increase (P < 0.05) in body weight gain at the seventh week of pregnancy. Toward the end of pregnancy (last seven weeks) the ewes with twin lambs had a significantly higher PBI level than the ewes with single lambs. The higher PBI levels remain elevated after parturition until the end of the lactation period. The PBI levels of lambs implanted with 3 and 6 mg diethystilbestroi (DES) were determined. Female lambs had a higher PBI level than mature ewes. Ten days after DES implantation, a significant (P < 0.001) increase in PBI levels was observed. This was followed by an increase in body weight gain over the control of 35% and 37% for 3 and 6 mg DES implants respectively during the remaining part of the experiment. There was a difference in the response to DES treatment between sexes. The wethers grew faster than the female lambs; this difference in growth rate can be reduced by treating the ewes with a larger dose of DES. Iodinated casein (protamone trade name, 1% thyroid activity) fed at 0, 0.25, 0.5 and 1 gm and also in combination with 1.75 mg DES were fed daily to growing lambs. The results showed that Protamone feeding to lambs as well as in combination with DES, caused a significant increase in PBI levels over the controls (P < 0.001). Blood glucose measurements showed a parallel with PBI in fluctuation. The blood sugar levels of lambs were found to be higher than those of mature ewes. DES and Protamone feeding caused an increase rate of gain over the control (DES 13.2 lb; 0.25 gm Protamone 8.7 lb)and improved feed efficiency (DES 1:3.4; Protamone 1:3.9 and control 1:5.6).

description: Analyses of multifactorial experimental designs are used as an explorative technique describing hypothesized multifactorial effects based on their variation. The procedure of analyzing multifactorial designs is well established for univariate data, and it is known as analysis of variance (ANOVA) tests, whereas only a few methods have been developed for multivariate data. In this work, we present the weighted-effect ASCA, named WE-ASCA, as an enhanced version of ANOVA-simultaneous component analysis (ASCA) to deal with multivariate data in unbalanced multifactorial designs. The core of our work is to use general linear models (GLMs) in decomposing the response matrix into a design matrix and a parameter matrix, while the main improvement in WE-ASCA is to implement the weighted-effect (WE) coding in the design matrix. This WE-coding introduces a unique solution to solve GLMs and satisfies a constrain in which the sum of all level effects of a categorical variable equal to zero. To assess the WE-ASCA performance, two applications were demonstrated using a biomedical Raman spectral data set consisting of mice colorectal tissue. The results revealed that WE-ASCA is ideally suitable for analyzing unbalanced designs. Furthermore, if WE-ASCA is applied as a preprocessing tool, the classification performance and its reproducibility can significantly improve.
Soils and soil capability classification for forestry of the Mission Tree Farm

description: A study of the soils and soil capability classification for forestry of the Mission Tree Farm Licence No. 26 was carried out. The soil survey and soil chemical analyses were done in cooperation with the British Columbia Department of Agriculture, Soils Division, Kelowna, B. C. The purposes of the study were: to characterize the soils found in Compartment One, to determine the forest capability of these soils, to recommend management practices for these soils for forestry purposes, and to compare soil mapping at scales of 1:12,000, 1:15,840, 1:31,680, and 1:63,360. Fourteen soil series were recognized and used as criteria for the mapping units in this area. Ten soil series were established, described, and chemically characterized. Although the soil series could be morphologically recognized in the field, the chemical analyses exhibited very little characteristic differences among the series. Vegetation could not be used consistently as criteria for differentiating among the various mapping units. Landform was the chief aid in establishing the extent of the soil mapping units. Each soil series was rated for capability to produce commercial forest growth. The major tree species involved were western hemlock, Douglas-fir, and western red cedar. The soils were evaluated for forest management practices including, reforestation, road building, erodibility, logging practices, and species adaptation to specific soils. Four scales of mapping were compared and discussed in relation to their uses for specific purposes. For an area such as Compartment One on which good forest management is being practiced, mapping at the scale of 1:15,840 was ideal.

The biogeochemistry and pedogeochemistry of the West Hercules area, Rosebery, western Tasmania
Creators: name: Russell, DW
Publisher: name: University Of Tasmania
Year: 2023

description: Sixteen plant species were sampled over a known pedogeochemical anomaly at West Hercules, Rosebery. This orientation survey was conducted to assess the potential of biogeochemical surveys in the West Coast-type rainforests. Three species were subsequently re-sampled in order to determine the most sensitive plant organ for biogeochemical prospecting. Both a detailed pilot survey and an independent trial survey proved that young Nothofagus cunninghamii leaves accurately and precisely reflected the soil-lead concentrations. The primary plant-ash data can be enhanced with the use of selected elemental ratios. A litter survey down five cut grid lines showed that plant-litter has great potential for reflecting elemental concentrations in the soil. Thirty soil pits were dug and sampled every ten centimetres, both on and off the pedogeochemical anomaly. The samples came from areas with potential copper, lead and zinc mineralization and analyses have been restricted to these elements and potential scavengers. Chemical analyses for carbon, Cu, Pb, Zn, Ni, Fe and Mn revealed a distinct vertical and horizontal distribution that could be explained by changes in Eh/pH environment and presence of \metal scavengers\". A sequential analysis of the soils indicated which elements were distributed over which soil phases. Copper was sorbed in the clay while lead and zinc were occluded in the iron and manganese oxides. The organic matter present in the soil complexed iron manganese lead and zinc. The geochemical pedological and topographic data indicated that the pedogeochemical anomaly at West Hercules was a hydromorphic anomaly formed by seepage of groundwater from the upslope Hercules Host Rocks."

description: © 2017 The Author(s). Advancements in nanoscale engineering of oxide interfaces and heterostructures have led to discoveries of emergent phenomena and new artificial materials. Combining the strengths of reactive molecular-beam epitaxy and pulsed-laser deposition, we show here, with examples of Sr1+x Ti1-x O3+δ, Ruddlesden-Popper phase La n+1Ni n O3n+1 (n = 4), and LaAl1+y O3(1+0.5y)/SrTiO3 interfaces, that atomic layer-by-layer laser molecular-beam epitaxy significantly advances the state of the art in constructing oxide materials with atomic layer precision and control over stoichiometry. With atomic layer-by-layer laser molecular-beam epitaxy we have produced conducting LaAlO3/SrTiO3 interfaces at high oxygen pressures that show no evidence of oxygen vacancies, a capability not accessible by existing techniques. The carrier density of the interfacial two-dimensional electron gas thus obtained agrees quantitatively with the electronic reconstruction mechanism.

description: Recently Horava proposed a renormalizable gravity theory in four dimensions which reduces to Einstein gravity with a non-vanishing cosmological constant in IR but with improved UV behaviors. Here, I study an IR modification which breaks "softly" the detailed balance condition in Horava model and allows the asymptotically flat limit as well. I obtain the black hole and cosmological solutions for "arbitrary" cosmological constant that represent the analogs of the standard Schwartzschild-(A)dS solutions which can be asymptotically (A)dS as well as flat and I discuss some thermodynamical properties. I also obtain solutions for FRW metric with an arbitrary cosmological constant. I study its implication to the dark energy and find that it seems to be consistent with current observational data.

description: Stress factors caused by inadequate storage can induce the unwanted degradation of active compounds in pharmaceutical formulations. Resonance Raman spectroscopy is presented as an analytical tool for rapid monitoring of small concentration changes of tetracycline and the metabolite 4-epianhydrotetracycline. These degradation processes were experimentally induced by changes in temperature, humidity, and irradiation with visible light over a time period of up to 23 days. The excitation wavelength ?exc = 413 nm was proven to provide short acquisition times for the simultaneous Raman spectroscopic detection of the degradation of tetracycline and production of its impurity in small sample volumes. Small concentration changes could be detected (down to 1.4% for tetracycline and 0.3% for 4-epianhydrotetracycline), which shows the potential of resonance Raman spectroscopy for analyzing the decomposition of pharmaceutical products. © 2020 by the authors.

description: © 2016 The Authors. Obesity Science & Practice published by John Wiley & Sons Ltd, World Obesity and The Obesity Society. Purpose: Half of adult cancer survivors under age 50 years are obese. Excess body weight is associated with cancer recurrence, and effective weight loss interventions for younger cancer survivors are needed. Commercially available, online weight loss programmes are readily accessible, but few have been studied in this population. This study employed a single-arm, pre-post intervention (baseline-6 month/baseline-12 month comparisons) to preliminarily explore feasibility, efficacy and safety of an online, commercially available weight loss programme in breast (n = 30) and testicular (n = 16) cancer survivors under age 50 years. Methods: The intervention included three daily components: exercise, nutritional/behavioural modification strategies and health lessons. Intention-to-treat and completers analyses were conducted. Feasibility was measured by participation (number of participants enrolled/number screened), retention (number of participants attending 6/12 month study visit/number of enrolled) and self-reported adherence rates (average of mean percent adherence to each of the three intervention components). Efficacy was assessed by changes in initial weight (percent weight loss). Safety was assessed by adverse events. Results: The mean participation rate was 42%. The retention rate was 59% at 6 and 49% at 12 months. The adherence rate for all participants (completers/dropouts/lost-to-follow-up) was 50.1% at 6 and 44% at 12 months. Completers reported adherence rates of 68% at 12 months. Study participants lost 5.3% body weight at 12 months; completers lost 9%. Only three unexpected adverse events (unrelated to the intervention) were reported. Conclusion: Clinically significant weight loss was observed, although retention rates were low. Findings generally support preliminary feasibility, efficacy and safety of this online weight loss programme, and future randomized control trials should be explored.

description: Acoustic wave generation by turbulence in the stratified, moist atmosphere is studied. It is shown that in the saturated moist air turbulence in addition to the Lighthill's quadrupole and the dipole sources of sound related to stratification and temperature fluctuations, there exist monopole sources related to heat and mass production during the condensation of moisture. We determine acoustic power of these monopole sources. Performed analysis shows that the monopole radiation is dominant for typical parameters of strong convective storms. Obtained results are in good qualitative agreement with the main observed characteristics of infrasound radiation by strong convective storms such as total acoustic power and characteristic frequency.

description: Chemotherapy-induced peripheral neuropathy (CIPN) is a type of neuropathic pain that represents a frequent and serious consequence of chemotherapy agents. Over the last years, significant progress has been achieved in elucidating the underlying pathogenesis of CIPN. The interference of taxanes with microtubule has been proposed as a mechanism that leads to altered axonal transport and to permanent neurological damages. The inflammatory process activated by chemotherapeutic agents has been considered as a potential trigger of nociceptive process in CIPN.In this study we investigated the effect of reparixin, an inhibitor of CXCR1/CXCR2, in suppressing the development of paclitaxel-induced nociception in rats. Moreover, reparixin activity in reversing the neurotoxic effects induced by paclitaxel or GRO/KC in F11 cells was also analyzed.Reparixin administered by continuous infusion ameliorated paclitaxel-induced mechanical and cold allodynia in rats. In F11 cells, reparixin was able to inhibit the increase of acetyladed α-tubulin induced both by paclitaxel and GRO/KC. The subsequent experiments were performed in order to dissect the signal transduction pathways under GRO/KC control, eventually modulated by paclitaxel and/or reparixin. To this aim we found that reparixin significantly counteracted p-FAK, p-JAK2/p-STAT3, and PI3K-p-cortactin activation induced either by paclitaxel or GRO/KC.Overall the present results have identified IL-8/CXCR1/2 pathway as a mechanism involved in paclitaxel-induced peripheral neuropathy. In particular, the obtained data suggest that the inhibition of CXCR1/2 combined with standard taxane therapy, in addition to potentiating the taxane anti-tumor activity can reduce chemotherapy-induced neurotoxicity, thus giving some insight for the development of novel treatments.

description: This paper proposes novel low-profile differential-fed planar antennas with embedded sharp frequency selectively. The antennas are compact and easy to integrate with differential devices without matching baluns. The antenna design is formulated as a topology optimization problem, where requirements on impedance bandwidth, directivity, and filtering are used as the design objectives. The optimized antennas operate over the frequency band 6.0-8.5 GHz. The antennas have reflection coefficients below -15 dB, cross-polarization levels below -42 dB, a maximum gain of 6.0 ± 0.5 dB, and a uniform directivity over more than 130° beamwidth angle in the frequency band of interest. In addition, the antennas exhibit sharp roll-off between the operational band and frequencies around the 5.8GHz WiFi band and the 10 GHz X-band. One antenna has been fabricated with a good match between simulation and measurement results. © 2019 by the authors. Licensee MDPI, Basel, Switzerland.

description: The combination of high spatial and spectral resolution in optical astronomy enables new observational approaches to many open problems in stellar and circumstellar astrophysics. However, constructing a high-resolution spectrograph for an interferometer is a costly and time-intensive undertaking. Our aim is to show that, by coupling existing high-resolution spectrographs to existing interferometers, one could observe in the domain of high spectral and spatial resolution, and avoid the construction of a new complex and expensive instrument. We investigate in this article the different challenges which arise from combining an interferometer with a high-resolution spectrograph. The requirements for the different sub-systems are determined, with special attention given to the problems of fringe tracking and dispersion. A concept study for the combination of the VLTI (Very Large Telescope Interferometer) with UVES (UV-Visual Echelle Spectrograph) is carried out, and several other specific instrument pairings are discussed. We show that the proposed combination of an interferometer with a high-resolution spectrograph is indeed feasible with current technology, for a fraction of the cost of building a whole new spectrograph. The impact on the existing instruments and their ongoing programs would be minimal.

description: Nanoplasmonics has recently experienced explosive development with many novel ideas and dramatic achievements in both fundamentals and applications. The spaser has been predicted and observed experimentally as an active element -- generator of coherent local fields. Even greater progress will be achieved if the spaser could function as a ultrafast nanoamplifier -- an optical counterpart of the MOSFET (metal-oxide-semiconductor field-effect transistor). A formidable problem with this is that the spaser has the inherent feedback causing quantum generation of nanolocalized surface plasmons and saturation and consequent elimination of the net gain, making it unsuitable for amplification. We have overcome this inherent problem and shown that the spaser can perform functions of an ultrafast nanoamplifier in two modes: transient and bistable. On the basis of quantum density matrix (optical Bloch) equations we have shown that the spaser amplifies with gain greater than 50, the switching time less or on the order of 100 fs (potentially, 10 fs). This prospective spaser technology will further broaden both fundamental and applied horizons of nanoscience, in particular, enabling ultrafast microprocessors working at 10 to 100 THz clock speed. Other prospective applications are in ultrasensing, ultradense and ultrafast information storage, and biomedicine. The spasers are based on metals and, in contrast to semiconductors, are highly resistive to ionizing radiation, high temperatures, microwave radiation, and other adverse environments.

description: We construct the chiral gravitational waves from the $z=2$ Hořava-Lifshitz gravity with gravitational Chern-Simons term in the de Sitter and Minkowski backgrounds. These gravitational waves which show a feature of the Hořava-Lifshitz gravity may be related to the generalized uncertainty principle. In addition, we find the classical and quantum IR-UV transition rules in the $z=2$ Hořava-Lifshitz gravity.
