description: The study focused on the binary system 6OCB and 8OCB, which is well-suited for investigating stable re-entrant nematic-phase transitions. High-resolution measurements of heat capacity and birefringence are used to analyse critical behaviours near the nematic – smectic-A (N-SmA) and the smectic-A – re-entrant nematic (SmA-NR) phase transitions. The critical behaviour of these transitions has been explored with the aid of a differential quotient extracted from the birefringenceΔnvalues. Simultaneously, critical exponents extracted from the specific heat capacity anomaly are also used to analyse the critical behaviour of the phase transition. The results indicate that the SmA to NR phase transition exhibits non-universal behaviour, with effective exponents falling between the tricritical (TCP) and 3D-XY values, similar to the N-SmA phase transition. The study reveals the existence of two tricritical points: one associated with the N-SmA transition and the other corresponding to the SmA-NR transition. This is supported by plotting the McMillan ratio against the critical exponents obtained from both birefringence and specific heat capacity anomaly. Again, with an increase in the SmA range, the SmA-NR transition tends towards the tricritical point (TCP), suggesting a relationship between the SmA range and the transitional behaviour.

description: RESUMO

O objetivo do presente estudo foi verificar o efeito crônico do treinamento de força de membros inferiores com diferentes frequências de vibração localizada sobre a corrida de velocidade. Após a realização de um teste de velocidade de corrida de 40m (V40m), 55 homens, não treinados, foram distribuídos em quatro grupos: Isométrico, vibração localizada com frequência de 8-Hz, vibração localizada com frequência de 26-Hz e Controle. Após as 4 semanas de treinamento foi realizado novamente o teste V40m. A comparação das médias dos quatro grupos nas etapas de pré e pós-teste foi realizada a partir da ANOVA com Medidas Repetidas e post hoc de Tukey. Não foram encontradas diferenças significativas entre os valores de velocidade média no teste V40m entre o pré-teste e pós-teste para nenhum dos quatro grupos citados. A partir dos resultados encontrados, foi possível concluir que o treinamento de força com aplicação de vibração localizada na direção da resultante das forças musculares, com frequências de 8 e 26 Hz, não foi capaz de aumentar a velocidade de corrida.

description: Minced grey cod fillets were inoculated with lactic acid bacteria starter cultures namely, Pediococcus cerevisiae (Lactacel 75, No. L750480, Microlife Technics) and a mixture of Pediococcus cerevisiae and Lactobacillus plantarum (Lactacel MC, No. M12772, Microlife Technics). Results showed that when lactic acid bacteria was added to the minced product to a final cell population of 10⁸ or 10⁹/g of mince, growth of psychrotrophic bacteria at normal refrigeration temperature was inhibited. Inhibition was more pronounced with the addition of 0.3% dextrose. This study points towards the potential application for utilizing lactic acid bacteria to preserve the quality of a refrigerated minced fish product. Potential application of the use of lactic acid bacteria, through a dipping procedure to extend the storage life of fish fillets, is also discussed.

description: We make predictions for the metallicity of diffuse stellar components in systems ranging from small spiral galaxies to rich galaxy clusters. We extend the formalism of Purcell et al. (2007), in which diffuse stellar mass is produced via galaxy disruption, and we convolve this result with the observed mass-metallicity relation for galaxies in order to analyze the chemical abundance of intrahalo light (IHL) in host halos with virial mass 10^10.5 M_sun < M_host < 10^15 M_sun. We predict a steep rise of roughly two dex in IHL metallicity from the scales of small to large spiral galaxies. In terms of the total dynamical mass M_host of the host systems under consideration, we predict diffuse light metallicities ranging from Z_IHL < -2.5 for M_host ~ 10^11 M_sun, to Z_IHL ~ -1.0 for M_host ~ 10^12 M_sun. In larger systems, we predict a gradual flattening of this trend with Z_IHL ~ -0.4 for M_host ~ 10^13 M_sun, increasing to Z_IHL ~ 0.1 for M_host ~ 10^15 M_sun. This behavior is coincident with a narrowing of the intrahalo metallicity distribution as host mass increases. The observable distinction in surface brightness between old, metal-poor IHL stars and more metal-rich, dynamically-younger tidal streams is of crucial importance when estimating the chemical abundance of an intrahalo population with multiple origins.

description: Recent work in multi-agent reinforcement learning has investigated inter agent communication which is learned simultaneously with the action policy in order to improve the team reward. In this paper, we investigate independent Q-learning (IQL) without communication and differentiable inter-agent learning (DIAL) with learned communication on an adaptive traffic control system (ATCS). In real world ATCS, it is impossible to present the full state of the environment to every agent so in our simulation, the individual agents will only have a limited observation of the full state of the environment. The ATCS will be simulated using the Simulation of Urban MObility (SUMO) traffic simulator in which two connected intersections are simulated. Every intersection is controlled by an agent which has the ability to change the direction of the traffic flow. Our results show that a DIAL agent outperforms an independent Q-learner on both training time and on maximum achieved reward as it is able to share relevant information with the other agents.

description: 5CB liquid crystal (LC) is a well-studied material for a variety of applications due to its orientational ordering and viscosity. LCs mostly suffer from ionic impurities which can be filtered using metal oxide nanoparticles. Beyond this conventional role of TiO2 nanoparticles (NPs) in ionic impurity filtration in LCs, we have employed a new methodology to improve the planar orientation of 5CB molecules by depositing a thin layer of NPs on either side of the ITO electrode. The 5CB LC exhibits a typical birefringent schlieren texture; however, the presence of TiO2 layer alters the molecular orientation. On the TiO2 surface, the 5CB LC molecules showed schlieren defect points characterised by both twofold (s = ± 1/2) and fourfold (s = ± 1) brush-like structures. The change in texture and lowering of dielectric permittivity might be attributed to the change in the pretilt angle of 5CB molecules owing to the mutual interactions between 5CB and TiO2 layer. Remarkably, the 5CB LC within the TiO2-coated cell attains the isotropic phase at lower temperature as compared to the cells coated with polyimide SE-130. The underlying mechanism for coarsening kinetics in the 5CB is elucidated using the Lifshitz-Slyozov-Wagner (LSW) theory.

description: Postural sway variability was evaluated in Parkinson’s disease (PD) patients at different stages of disease. Twenty PD patients were grouped into two groups (unilateral, 14; bilateral, 6) according to disease severity. The results showed no significant differences in postural sway variability between the groups (p ≥ 0.05). Postural sway variability was higher in the antero-posterior direction and with the eyes closed. Significant differences between the unilateral and bilateral groups were observed in clinical tests (UPDRS, Berg Balance Scale, and retropulsion test; p ≤ 0.05, all). Postural sway variability was unaffected by disease severity, indicating that neurological mechanisms for postural control still function at advanced stages of disease. Postural sway instability appears to occur in the antero-posterior direction to compensate for the stooped posture. The eyes-closed condition during upright stance appears to be challenging for PD patients because of the associated sensory integration deficit. Finally, objective measures such as postural sway variability may be more reliable than clinical tests to evaluate changes in balance control in PD patients.

description: We present the results of H- and K-band VLT/SINFONI integral field spectroscopy of the ULIRG IRAS 19254-7245 (The Super-antennae), an interacting double galaxy system containing an embedded AGN. Deep K-band spectroscopy reveals PaAlpha arising in a warped disc with position angle of 330 degree and an inclination i=40-55 degree. The kinemetric parameters derived for H2 are similar to PaAlpha. Two high-ionization emission lines, [SiVI] and [AlIX], are detected and we identify as [NiII] the line observed at 1.94 micron. Diluting non-stellar continuum, which was previously detected, has decayed, and the H-band continuum emission is consistent with pure stellar emission. Based on H2 emission line ratios it is likely that at the central 1-kpc region H2 is excited by UV fluorescence in dense clouds while shock excitation is dominant further out. This scenario is supported by very low PaAlpha to H2 line ratio detected outside the nuclear region and non-thermal ortho/para ratios (~2.0 - 2.5) close to the nucleus.

description: The study investigated the role of motivation and metacognition in the formation of cognitive and affective outcomes from participation in physical education lessons within the framework of self-determination theory. A sample of 630 adolescents (M age = 14.06, SD = .29) participated in the study. Participants completed questionnaires including measures of perceived autonomy support in PE, autonomous motivation in PE, metacognitive processes in PE, enjoyment, boredom in PE and intention for leisure-time physical activity. Multiple linear regression analyses revealed that perceptions of autonomy supportive motivational climate significantly predicted enjoyment, boredom and intentions towards leisure-time physical activity. In addition autonomous motivation and metacognition significantly predicted enjoyment, boredom and intentions, whereas controlling motivation was a significant predictor of boredom. Multiple mediation modeling indicated that perceptions of autonomy supporting climate on these responses was mediated mainly by autonomous motivation and metacognition. The findings of the present study provide valuable information on the mediating role of autonomous motivation and metacognition on the effects of autonomy supportive motivational climate on students’ cognitive and affective responses during physical education lessons.

description: The aim of this study was to analyze the relationship between physical activity (PA) and total body (BLM), leg (LLM) and arm lean mass (ALM) in menopausal women. Sixty two 62 menopausal women were included (61.2±7.6 years). Their practice of PA was assessed by Actigraph GT3X accelerometer, and is reported as minutes per week of light or moderate-vigorous PA, and total PA. The sample was dichotomized into two groups according to their weekly practice of PA moderate-vigorous; physically active (≥150 minutes) and insufficiently active (<150 minutes). Body composition measures were assessed by DXA and were reported as percentages. Comparisons between the groups of PA and total and segmental lean body mass were performed by independent t test. Association between the tertile of BLM and the groups of PA were performed by chi-square test. Physically active women showed significantly higher mean values for BLM (52.8±5.4 vs 49.8±4.7; p=0.028) and LLM (17.1±2.2 vs 15.9±1.8; p=0.026), whereas the difference in the ALM was not significant. When the BLM was categorized into tertiles, it was significantly greater in physically active women (higher tertile=44.7%), compared with the insufficiently active women (higher tertile=16.7%). Menopausal women who spent more minutes engaged in moderate-vigorous PA can showed higher BLM and LLM.

description: The cover shows the set-up and the key results of the element $Z=115$ experiment conducted at GSI's gas-filled recoil separator TASCA. The $\alpha$-photon coincidence spectroscopy set-up TASISpec consists of a box of pixelated Si-detectors with surrounding composite Ge-detectors (schematic representation top right). This setup allows detecting superheavy nuclei via their implantation and subsequent nuclear decay and their direct identification by measuring characteristic $X$ rays. \\For the experiment an intense $^{48}$Ca beam provided by the UNILAC accelerator impinged on a radioactive $^{243}$Am target wheel placed at the entrance to TASCA (photo bottom left).  30 correlated $\alpha$-decay chains, assigned to element 115, were registered in TASISpec within three weeks. Twenty-two of them originated from the isotope with mass number 288 (average values given in the displayed chain at the diagonal). Observed $\alpha$-photon coincidences (black histograms, upper left) include two $K$ $X$-ray candidates along the decay chain, the energies of which are compatible with the assignment of the chains to element $Z=115$. Further coincidences led for the first time to detailed decay schemes (lower right) of superheavy elements near the predicted 'Island of Stability'. The $E1$ $\gamma$ rays in $^{276}$Mt give rise to significant constraints on nuclear structure models. A complex, but in parts still tentative, decay scheme of $^{272}$Bh can explain the emission of the two $K$ $X$-ray candidates. Detailed GEANT4 Monte-Carlo simulations (see TASISpec scheme, top right) were employed for the first time in an experiment on such superheavy nuclei. They allow for a crucial self-consistency check of the interpretation (decay schemes, bottom right) of the measured data (spectra, green curves, top left).\\This experiment was selected by the American Physics Society as one of the top ten 'Physics Newsmakers of the Year 2013'.

description: We explore the Magellanic Stream (MS) using a Gaussian decomposition of the HI velocity profiles in the Leiden-Argentine-Bonn (LAB) all-sky HI survey. This decomposition exposes the MS to be composed of two filaments distinct both spatially (as first pointed out by Putman et al.) and in velocity. Using the velocity coherence of the filaments, one can be traced back to its origin in what we identify as the SouthEast HI Overdensity (SEHO) of the Large Magellanic Cloud (LMC), which includes 30 Doradus. Parts of the Leading Arm (LA) can also be traced back to the SEHO in velocity and position. Therefore, at least one-half of the trailing Stream and most of the LA originates in the LMC, contrary to previous assertions that both the MS and the LA originate in the Small Magellanic Cloud (SMC) and/or in the Magellanic Bridge. The two MS filaments show strong periodic, undulating spatial and velocity patterns that we speculate are an imprint of the LMC rotation curve. If true, then the drift rate of the Stream gas away from the Magellanic Clouds is ~49 km/s and the age of the MS is ~1.74 Gyr. The Staveley-Smith et al. high-resolution HI data of the LMC show gas outflows from supergiant shells in the SEHO that seem to be creating the LA and LMC filament of the MS. Blowout of LMC gas is an effect not previously accounted for but one that probably plays an important role in creating the MS and LA.

description: In this addendum to Phys.Rev. D74 (2006) 023502, we present an update of cosmological constraints on single-field inflation in light of the Wilkinson Microwave Ansiotropy Probe satellite mission five-year results (WMAP5). We find that the cosmic microwave background data are quite consistent with a Harrison-Zel'dovich primordial spectrum with no running and zero tensor amplitude. We find that the three main conclusions of our analysis of the WMAP three-year data (WMAP3) are consistent with the WMAP5 data: (1) the Harrison--Zel'dovich model is within the 95% confidence level contours; (2) there is no evidence for running of the spectral index of scalar perturbations; (3) From the WMAP 5 data alone, potentials of the form $V \propto ϕ^p$ are consistent with the data for $p = 2$, and are ruled out for $p = 4$. Furthermore, consistent with our WMAP3 analysis, we find no evidence for primordial tensor perturbations, this time with a 95% confidence upper limit of $r < 0.4$ for the WMAP5 data alone, and $r < 0.35$ for the WMAP5 data taken in combination with the Arcminute Cosmology Bolometer Array (ACBAR).

description: Whether the things we love are truly things or people or places, we love them because they are a part of us. As a writer, I remember special moments, carry special memories, and when writing poems, try to recall and put into words of special meaning these recollections. I try to recreate that time, that place, that person and look for the best words I can find, then put them in their best order to make my poetry. My early years in the country, among country things and people, have given me a real feel for earthy simple things.

Just as influential are books and their authors. As Denise Levertov has said, all of them “are in the poet's mind,” When my writing begins, therefore, the page isn't really blank. There, invisible before me, are those poems and stories remembered from years of reading, the ones that rema.in long after the exact wording has been forgotten. I remember the flavor of Robert Frost's poems of New England, Wendell Berry's poems of country farms, Maxine Kumin's poems about horses.

Poets of other years also help to make up the broad base of this compiled influence. Wordsworth's and Yeats' poems are equally as much a part of this heritage as the contemporary poets mentioned before.

The poems in Over My Shoulder picture a little of this influence, Childhood experiences become vivid, As Robert Frost recalled what it was like to swing on young birches, so in “Chicken Plucking" and “Eggs” of Section I, I have remembered those very special times in my youth. I have tried to speak with clarity and brevity, using the familiar voice of country people, unadorned with rhetorical devices.

Section II contains poems of wider scope, dealing with people known only through second-hand knowledge, easily recognizable and important in their influence, Who could read about John Milton without recognizing his daughters? Or Anne Bradstreet without remembering her amazing outpouring of poetry in the wilderness of America in the 1600’s?

The technical tools used in Over My Shoulder vary. Free verse is generally used--rhyme avoided. I tried to make sounds, rhythms and imagery as vivid as possible. The circular concept is evident in several poems; "Eggs" is one, "Baby, Baby” another.

As a unit, My Shoulder attempts to make one complete statement: that "we love the things we love for what they are"--memories of things past, books read and people remembered, and the tell these things helped me form these poems.

description: In the era of rapid development of informatization, the informatization construction of national higher vocational colleges has been in the period of application deepening. China's education system is deepening to the development of mass education, and higher vocational colleges’ adult continuing education plays a great role for the realization of education popularization. With the continuous expansion of continuing education enrollment scale, the diversified development of education mode, the higher complexity of continuing education management and the increase of management workload, the traditional management method has gradually become unapplicable. Higher vocational colleges can greatly improve the management level by promoting the informatization of education management according to their own professional or regional advantages.

description: A new series of liquid crystal dimers, 4-cyano-1,3-phenylene bis(4-((4’-cyano-[1,1’−biphenyl]-n-yl)oxy)alkanoate), has been synthesised and confirmed for their molecular structure using standard spectroscopic techniques. Thermal behaviour is assessed using optical polarising microscope (OPM), differential scanning calorimetry (DSC), and X-ray diffraction. Interestingly, all the dimers exhibit a super-cooled nematic phase without crystallisation during cooling cycles. These molecules self-assemble with head-on aggregation assessed by UV–Visible absorption spectra, and they also have a distinct fluorescence characteristic. A super-cooled nematogens self-assemble into head-on aggregation with a fluorescence property. Moreover, the materials were studied for their fluorescence properties and proved to be fluorescence active, making them excellent candidates to be used in designing photo-responsive optical sensor devices.

description: The DEK oncoprotein is a ubiquitous nuclear factor that has been consistently associated with tumor progression: its expression level differs between normal and cancer cells, raising the possibility of using DEK as a tumor marker. Moreover, DEK is a non-histone architectural chromatin factor that may influence nucleosomal accessibility and therefore gene activity. The interest of this work is to investigate, using super-resolution microscopy approaches, the correlation between the organization of the DEK oncoprotein and the local chromatin structure depending on the degree of cell malignancy. A model based on three well-established human breast cell lines was chosen to represent different subtypes of breast cancer (MCF10A, MCF7 and MDA-MB-231 cells). We performed dual-color confocal and STED imaging followed by the pixel intensity spatial correlation analysis, to show the differences of the nanoscale distribution of DEK in relation to the chromatin organization pattern (observed by particular histone modification immunostaining). We expect that this study will provide novel insights into the tumor-promoting activity of DEK and thus progress our understanding of basic mechanisms of cancerogenesis.

description: We consider the problem of generating rankings that are fair towards both users and item producers in recommender systems. We address both usual recommendation (e.g., of music or movies) and reciprocal recommendation (e.g., dating). Following concepts of distributive justice in welfare economics, our notion of fairness aims at increasing the utility of the worse-off individuals, which we formalize using the criterion of Lorenz efficiency. It guarantees that rankings are Pareto efficient, and that they maximally redistribute utility from better-off to worse-off, at a given level of overall utility. We propose to generate rankings by maximizing concave welfare functions, and develop an efficient inference procedure based on the Frank-Wolfe algorithm. We prove that unlike existing approaches based on fairness constraints, our approach always produces fair rankings. Our experiments also show that it increases the utility of the worse-off at lower costs in terms of overall utility.

description: Speech enhancement attenuates interfering sounds in speech signals but may introduce artifacts that perceivably deteriorate the output signal. We propose a method for controlling the trade-off between the attenuation of the interfering background signal and the loss of sound quality. A deep neural network estimates the attenuation of the separated background signal such that the sound quality, quantified using the Artifact-related Perceptual Score, meets an adjustable target. Subjective evaluations indicate that consistent sound quality is obtained across various input signals. Our experiments show that the proposed method is able to control the trade-off with an accuracy that is adequate for real-world dialogue enhancement applications.

description: A novel family of rod-like liquid crystals designed by Prof. G.W. Gray having nematic phase has been extensively used to make stable informative liquid crystal displays. These 4’-alkyl- and 4’-alkoxy-4-cyanobiphenyl molecules were created using his extensive understanding of liquid crystal chemical structure and physical properties. Following the discovery of this family of nematogens for display applications, the development of liquid crystal molecule designing and synthesising has resulted in the emergence of a broad new family of functional liquid crystals. This feature article presents the review of reports on the liquid-crystalline behaviour of 4-cyanobiphenyl-based oligomeric systems, which are ‘in-between’ polymeric and low molar mass systems and exhibit distinct molecular structures.

description: This dissertation focuses on “organizational efficacy”, in particular on employees’ beliefs of organizational capacity to be efficacious. Organizational efficacy is considered from two perspectives – competing values approach and collective efficacy, and evaluated in internationalized companies. The dissertation is composed of three studies. The data were collected in thirteen Italian companies on different stages of internationalization for a total number of respondents is 358. In the first study the factorial validity of the competing values instrument (Rohrbaugh, 1981) was investigated and confirmed. Two scales were used to measure collective efficacy: a general collective efficacy scale (Bohn, 2010),  and a specific collective efficacy scale, developed following suggestions of Borgogni et al. (2001), it evaluates employees’ beliefs of efficacy of organizations in the international market. The findings suggest that competing values and collective organizational efficacy instruments may provide a multi-faceted measurement of employees’ beliefs of organizational efficacy. The second study examined the relationship between organizational efficacy and collective work engagement. To measure collective work engagement the UWES-9 (Schaufeli & Bakker, 2003) was adapted at the group level; its factor structure and reliability were similar to the standard UWES-9. The findings suggest that organizational efficacy fully predicts collective work engagement. Also we investigated whether leadership moderates the relationship between organizational efficacy and collective work engagement. We operationalized leadership style with MLQ (Bass & Avolio, 1995); the results suggest that intellectual stimulation and idealized influence (transformational leadership) and contingent reward (transactional leadership) enhance the impact of organizational efficacy on collective work engagement. In the third study we investigated organizational efficacy and collective work engagement in internationalized companies. The findings show that beliefs of organizational efficacy vary across companies in different stages of internationalization, while no significant difference was found for collective work engagement. Limitations, practical implications and future studies are discussed in the conclusion.

description: The Performance and Development Framework for Principals, Executives and Teachers in New South Wales Public Schools (NSWPDF) was mandated for all State Government schools in 2015 and represented a culmination of educational reform around the gradual professionalisation of the teaching workforce.This thesis comprises the report of a study that explored the impact of the NSWPDF on teachers and teaching in Sydney government secondary schools The research investigated performance and development processes through principals’ and teachers’ perspectives to develop an understanding of the factors that promote and inhibit successful performance and development outcomes. The study considered the role of school leadership in positioning the structural capital required to leverage the school’s social capital to achieve the desired outcomes of the NSWPDF.This mixed methods study explored school principals’ actions, strategies and challenges in implementing the NSWPDF and teachers’ perceptions of the principal’s leadership style, the school’s culture, the structures developed to support the implementation of the NSWPDF and the degree to which outcomes are achieved. In a single-phase design, data were collected in guided interviews with principals and a teacher questionnaire. A newly developed Performance and Development Scale operationalised the constructs associated with the successful implementation of the NSWPDF. Results from the quantitative and qualitative data analysis were integrated and triangulated to provide a more holistic and nuanced understanding of the implementation of the NSWPDF.Findings were presented using the constructs of the study’s theoretical framework and model and suggest several factors that support the achievement of performance and development outcomes. Recommendations were made for further research into the leadership of performance and development in other educational jurisdictions and for more widespread use of the Performance and Development Scale for further methodological validation in other contexts.

description: Stellar models applied to large stellar surveys of the Milky Way need to be properly tested against a sample of stars with highly reliable fundamental stellar parameters. We have established a program aiming to deliver such a sample. We present new fundamental stellar parameters of nine dwarfs that will be used as benchmarks for large stellar surveys. One of these stars is the solar-twin 18Sco, which is one of the Gaia-ESO benchmarks. The goal is to reach a precision of 1% in Teff. This precision is important for accurate determinations of the full set of fundamental parameters and abundances of stars observed by the surveys. We observed HD131156 (xiBoo), HD146233 (18Sco), HD152391, HD173701, HD185395 (thetaCyg), HD186408 (16CygA), HD186427 (16CygB), HD190360 and HD207978 (15Peg) using the high angular resolution optical interferometric instrument PAVO/CHARA. We derived limb-darkening corrections from 3D model atmospheres and determined Teff directly from the Stefan-Boltzmann relation, with an iterative procedure to interpolate over tables of bolometric corrections. Surface gravities were estimated from comparisons to Dartmouth stellar evolution model tracks. We collected spectroscopic observations from the ELODIE spectrograph and estimated metallicities ([Fe/H]) from a 1D non-local thermodynamic equilibrium (NLTE) abundance analyses of unblended lines of neutral and singly ionized iron. For eight of the nine stars, we measure the Teff less than 1%, and for one star better than 2%. We determined the median uncertainties in logg and Fe/H as 0.015dex and 0.05dex, respectively. This study presents updated fundamental stellar parameters of nine dwarfs that can be used as a new set of benchmarks. All parameters were based on consistently combining interferometric observations, 3D limb-darkening modelling and spectroscopic analysis. The next paper will extend our sample to metal-rich giants.
