description: The degradation of spatial resolution in star-forming regions observed at large distances ($d\gtrsim1$ kpc) with Herschel,can lead to estimates of the physical parameters of the detected compact sources (clumps) which do not necessarily mirror the properties of the original population of cores. This paper aims at quantifying the bias introduced in the estimation of these parameters by the distance effect. To do so, we consider Herschel maps of nearby star-forming regions taken from the Herschel-Gould-Belt survey, and simulate the effect of increased distance to understand what amount of information is lost when a distant star-forming region is observed with Herschel resolution. In the maps displaced to different distances we extract compact sources, and we derive their physical parameters as if they were original Hi-GAL maps of the extracted source samples. In this way, we are able to discuss how the main physical properties change with distance. In particular, we discuss the ability of clumps to form massive stars: we estimate the fraction of distant sources that are classified as high-mass stars-forming objects due to their position in the mass vs radius diagram, that are only "false positives". We give also a threshold for high-mass star-formation $M>1282 \ \left(\frac{r}{[\mathrm{pc}]}\right)^{1.42} M_{\odot}$. In conclusion, this paper provides the astronomer dealing with Herschel maps of distant star-forming regions with a set of prescriptions to partially recover the character of the core population in unresolved clumps.

description: Many models of beyond Standard Model physics connect flavor symmetry with a discrete group. Having this symmetry arise spontaneously from a gauge theory maintains compatibility with quantum gravity and can be used to systematically prevent anomalies. We minimize a number of Higgs potentials that break gauge groups to discrete symmetries of interest, and examine their scalar mass spectra.

description: This paper reports new exclusive cross sections for $e p \to e' π^+ π^- p'$ using the CLAS detector at Jefferson Laboratory. These results are presented for the first time at photon virtualities 2.0 GeV^2 < Q^2 < 5.0 GeV^2 in the center-of-mass energy range 1.4 GeV < W < 2.0 GeV, which covers a large part of the nucleon resonance region. Using a model developed for the phenomenological analysis of electroproduction data, we see strong indications that the relative contributions from the resonant cross sections at W < 1.74 GeV increase with $Q^2$. These data considerably extend the kinematic reach of previous measurements. Exclusive $e p \to e' π^+ π^- p'$ cross section measurements are of particular importance for the extraction of resonance electrocouplings in the mass range above 1.6 GeV.

description: This paper reports on the frictional properties of smooth rubber substrates sliding against rigid surfaces covered with various densities of colloidal nano-particles (average diameter 77 nm). Friction experiments were carried out using a transparent Poly(dimethyl siloxane) (PDMS) rubber contacting a silica lens with silica nano-particles sintered onto its surface. Using a previously described methodology (Nguyen \textit{et al.}, \textit{J. of Adhesion} \textbf{87} (2011) 235-250 ), surface shear stress and contact-pressure distribution within the contact were determined from a measurement of the displacement field at the surface of the PDMS elastomer. Addition of silica nano-particles results in a strong, pressure-independent enhancement of the frictional shear stress as compared to the smooth lens. The contribution of viscoelastic losses to these increased frictional properties is analyzed in the light of a numerical model that solves the contact problem between the rubber and the rough surface. An order-of-magnitude agreement is obtained between experimental and theoretical results, the latter showing that the calculation of viscoelastic dissipation within the contact is very sensitive to the details of the topography of the rigid asperities.

description: This paper deals with the two-species chemotaxis-competition system $u_t = d_1 Δu - χ_1 \nabla \cdot (u \nabla w) + μ_1 u(1 - u - a_1 v)$, $v_t = d_2 Δv - χ_2 \nabla \cdot (v \nabla w) + μ_2 v(1 - a_2 u - v)$, $0 = d_3 Δw + αu + βv - γw$, where $Ω$ is a bounded domain in $\mathbb{R}^n$ with smooth boundary, $n\ge 2$; $χ_i$ and $μ_i$ are constants satisfying some conditions. The above system was studied in the cases that $a_1,a_2\in (0,1)$ and $a_1>1>a_2$, and it was proved that global existence and asymptotic stability hold when $\frac{χ_i}{μ_i}$ are small. However, the conditions in the above two cases strongly depend on $a_1,a_2$, and have not been obtained in the case that $a_1,a_2\ge 1$. Moreover, convergence rates in the cases that $a_1,a_2\in (0,1)$ and $a_1 > 1 > a_2$ have not been studied. The purpose of this work is to construct conditions which derive global existence of classical bounded solutions for all $a_1,a_2>0$ which covers the case that $a_1,a_2 \ge 1$, and lead to convergence rates for solutions of the above system in the cases that $a_1,a_2\in (0,1)$ and $a_1\ge 1 >a_2$.

Sound-induced contextual modulation of the representation of oriented visual stimuli in the primary visual cortex of awake behaving mice
Creators: name: McClure, John Patrick
Publisher: name: No Publisher Supplied
Year: 2020

description: The cerebral cortex is continuously receiving sensory information provided by the five senses. The role of sensory processing is to identify and integrate the sensory information necessary for the selection and execution of behaviors most adapted to the environmental conditions. Most of the time, combining or comparing the signals provided by different sensory modalities leads to optimal processing of the information. The mechanisms responsible for the interactions between at least two different sensory modalities are critical for the production of a relevant behavioral response. However, the cellular and network activities underpinning multimodal integration are poorly understood. For decades, scientist thought that multisensory interactions occur only in ‘higher-order’ cortical regions. Only recently, converging evidence has shown that part of cross-modal cortical integration occurs as early as the primary sensory cortices, such as the existence of direct cortico-cortical projections between the primary auditory cortex (A1) and the primary visual cortex (V1). Despite these findings, the effects of sounds on visually-evoked responses along with the influence of the audiovisual context on visual processing and visual perception remain unclear. Therefore, two-photon calcium imaging was performed in V1 of awake mice passively or actively processing oriented visual stimuli in order to determine the effect of sounds on visual processing. The results demonstrated an association between auditory stimulation and improvements on V1 representation of the orientation and the direction of the visual stimulus. This improvement of the representation of the visual stimulus was associated with a decrease in the limits of angular perception of mice performing an angular perception task. Finally, the results indicated that during active audiovisual processing, the modulation of the representation of the visual stimuli in V1 dynamically adapted to the needs of the behavioral task. Altogether, the results showed that other sensory modalities influence visual processing in V1 and visual perception, and are adaptable to the behavioral goal.

description: Music-based interventions are used in the treatment of childhood speech sound disorders (SSDs). Hypotheses on working mechanisms are being developed, focussing on shared neural processes. However, evidence of the effect of treatment with musical elements in SSDs in children is lacking. This study reviews the literature regarding the use of music-based interventions in the treatment of childhood SSDs. A systematic search in six databases was conducted, yielding 199 articles, eight of which met the inclusion criteria. Included articles were reviewed on study characteristics, patient characteristics, interventions, outcomes and methodological quality. This review included four case studies, three single-subject design studies and one cohort study. Seven studies reported positive outcomes on speech production, but outcome measures in the four studies with experimental design were not all aimed at the level of speech (motor) processes. Methodological quality was sufficient in one study. Seven out of eight studies in this review report positive outcomes of music-based interventions in the treatment of SSDs. However, these outcomes are not sufficiently supported by evidence due to insufficient methodological quality. Suggestions for improving methodological quality in future research are presented.

description: Timely speech-language pathology (SLP) involvement with dysphagic patients in the Emergency Department (ED) may improve patient outcomes. This study utilised qualitative interviews to understand current models and explore factors which have influenced establishment and current dysphagia service provision in Australian EDs. Semi-structured interviews were conducted with representatives from 12 acute hospital facilities with a SLP ED service. Interview transcripts were analysed using plain content analysis to identify key themes. Sub-analysis using the Consolidated Framework for Implementation Research (CFIR) model was undertaken for facilities with more “expanded” models (n = 4). SLP ED service models ranged from referral-only services, to models with referral-only and proactive SLP-led screening procedures (classified as “expanded”). Patient-related factors, the ED setting, SLP service factors and perceptions of dysphagia management were key themes reported to impact service delivery. With expanded models, 14 CFIR constructs (innovation source, external policy and incentives, networks and communications, stakeholders and relative priority) were identified as facilitators, while four constructs (adaptability, cost, compatibility, available resources) were barriers to services. There are service-specific issues with providing SLP care within the ED. Factors related to the unique ED environment must be considered by SLP departments when establishing/optimising dysphagia management within the ED.

description: There is growing emphasis on the importance of involving families in all aspects of the early speech–language pathology intervention process, however, both speech–language pathologists (SLPs) and families have reported that this can be challenging. To better understand how SLPs work together with families in intervention, this study aimed to (a) explore what SLPs do to support families to be actively involved in intervention, both inside and outside sessions, and (b) explore the perspectives of families regarding how SLPs supported their active involvement. Video-reflexive ethnography (VRE) was used to explore engagement with 21 matched SLP-family dyads in early intervention services. Up to three intervention appointments for each participating family were video recorded. Short video segments were selected and played to participants in individual semi-structured interviews where participants were invited to reflect on the interactions captured (i.e. “video-reflexive sessions”). Interview data were analysed using template analysis. Participants reported that SLPs supported families to be actively involved in sessions by (1) planning to involve families; (2) setting expectations; (3) modelling and teaching strategies; (4) inviting families to “have a go”; (5) providing feedback; and (6) problem solving together. Participants also reported that families were supported to be involved outside sessions when SLPs: (1) got them to practice in sessions; (2) made home practice achievable and provided resources; (3) asked about home practice; (4) linked home practice to progress; and (5) helped other family members get involved. The results of this study provide an explicit understanding of how SLPs can support families to take an active role in early intervention, and support the importance of a reflective and individualised approach to supporting engagement.

description: Guidelines recommend routine discourse assessment and treatment in paediatric acquired brain injury (ABI) but provide little guidance for clinical practice. The degree to which this has influenced the nature of discourse assessment and treatment in clinical practice has not been examined in detail. Speech-language pathologists working in paediatric ABI (clients aged <18 years) in Australia, New Zealand, the UK, the USA, Canada, and the Asia Pacific region were invited to complete a survey of discourse assessment and intervention practices (n = 77). Clinicians from Australia and New Zealand comprised over half of a responses (53%). The largest proportion had over 10 years’ experience (60%), worked in the metropolitan area (58%), and with secondary school-age children (64%). Routine discourse assessment was undertaken by 80% of respondents, focussing on a limited range of genres. No preferred intervention approach was identified. One-quarter of clinicians routinely considered holistic factors during clinical decision-making. Limited normative data and treatment evidence, insufficient time and training were identified as clinical barriers. Assessment practices were consistent with guidelines, yet interventions were highly variable, reflecting limited evidence, client heterogeneity, time constraints, and limited training. A biopsychosocial approach to practice was evident, yet a focus on impairment level factors was prominent. Findings support the need for standardised discourse assessment and discourse intervention methods. Translation into practice guidelines would promote consistency and confidence in clinical practice.

description: We investigate the properties of magnetized stars in the propeller regime using axisymmetric numerical simulations. We modelled the propeller regime for stars with realistically large magnetospheres (5-7 stellar radii), so that our results could be applied to different types of magnetized stars, including Classical T Tauri stars, cataclysmic variables, and accreting millisecond pulsars. A wide range of propeller strengths has been studied, from very strong propellers (where the magnetosphere rotates much more rapidly than the inner disk) to very weak propellers (where the magnetosphere rotates only slightly faster than the inner disc. In both propellers, matter is accumulated at the inner disc for the majority of the time, while episodes of accretion onto the star and ejection into the wind are relatively brief. The efficiency of the propeller, which characterizes the part of inner disk matter flowing into the wind, strongly depends on the fastness parameter omega_s: propeller efficiency increases with omega_s. The properties of the winds are different in strong and weak propellers. In the strong propellers, matter is accelerated rapidly above the escape velocity and flows at a relatively small opening angle of 40-45 degrees. In the weak propellers, matter may flow faster or slower than the escape velocity and at a large opening angle of 60-70 degrees. A star-disk system loses energy and angular momentum. A part of the rotational energy of the star is ejected to the magnetically-dominated (Poynting flux) jet, which is only present in the strong propellers. The other part of the energy flows from the inner disk into a propeller-driven wind. A star spins down partly due to the flow of angular momentum from the star to the corona or to the Poynting flux jet along the open field lines, and partly due to the flow of angular momentum to the inner disk along the closed field lines.

description: The discovery of topological states of matter has profoundly augmented our understanding of phase transitions in physical systems. Instead of local order parameters, topological phases are described by global topological invariants and are therefore robust against perturbations. A prominent example thereof is the two-dimensional integer quantum Hall effect. It is characterized by the first Chern number which manifests in the quantized Hall response induced by an external electric field. Generalizing the quantum Hall effect to four-dimensional systems leads to the appearance of a novel non-linear Hall response that is quantized as well, but described by a 4D topological invariant - the second Chern number. Here, we report on the first observation of a bulk response with intrinsic 4D topology and the measurement of the associated second Chern number. By implementing a 2D topological charge pump with ultracold bosonic atoms in an angled optical superlattice, we realize a dynamical version of the 4D integer quantum Hall effect. Using a small atom cloud as a local probe, we fully characterize the non-linear response of the system by in-situ imaging and site-resolved band mapping. Our findings pave the way to experimentally probe higher-dimensional quantum Hall systems, where new topological phases with exotic excitations are predicted.

description: The recently developed energy conserving semi-implicit method (ECsim) for PIC simulation is applied to multiple scale problems where the electron-scale physics needs to be only partially retained and the interest is on the macroscopic or ion-scale processes. Unlike hybrid methods, the ECsim is capable of providing kinetic electron information, such as wave-electron interaction (Landau damping or cyclotron resonance) and non-Maxwellian electron velocity distributions. However, like hybrid, the ECsim does not need to resolve all electron scales, allowing time steps and grid spacing orders of magnitude larger than in explicit PIC schemes. The additional advantage of the ECsim is that the stability at large scale is obtained while conserving energy exactly. Three examples are presented: ion acoustic waves, electron acoustic instability and reconnection processes.

description: We present a spin-rotation-invariant Green-function theory for the dynamic spin susceptibility in the spin-1/2 antiferromagnetic Heisenberg model on a stacked honeycomb lattice. Employing a generalized mean-field approximation for arbitrary temperatures, the thermodynamic quantities (two-spin correlation functions, internal energy, magnetic susceptibility, staggered magnetization, N'eel temperature, correlation length) and the spin-excitation spectrum are calculated by solving a coupled system of self-consistency equations for the correlation functions. The temperature dependence of the magnetic (uniform static) susceptibility is ascribed to antiferromagnetic short-range order. The Néel temperature is calculated for arbitrary interlayer couplings. Our results are in a good agreement with numerical computations for finite clusters and with available experimental data on the β-Cu2V2O2 compound.

description: Isolation of chiral molecules as pure enantiomers remains a fundamental challenge in chemical research. Enantioselective enrichment through preferential crystallization is an efficient method to achieve enantiopure compounds, but its applicability depends on the relative stability of the enantiopure and racemic crystal forms. Using a simple thermodynamic model and first-principles density-functional calculations, it is possible to predict the difference in solubility between the enantiopure and racemic solid phases. This approach uses dispersion-corrected density functionals and is capable of accurately predicting the solution-phase entantiomeric excess to within about 10 % of experimental measurements on average. The accuracy of the exchange-hole dipole moment (XDM) model of dispersion enables the viability of the proposed method.

description: This cross-national study investigates the experiences, needs and resilience of children and young people caring for parents or relatives with HIV/AIDS (‘young carers’) in Tanzania and the UK. This study explores similarities and differences in the experiences of this hidden group of young carers.

 The study aimed to understand children’s everyday experiences of unpaid care work in families affected by HIV/AIDS; the push and pull factors influencing whether and why they take on care-giving tasks; the outcomes for children and families; the factors that can reduce children’s vulnerability to negative outcomes and promote their ‘resilience’; caring relationships within families; and how young carers can best be supported in terms of policy and social welfare practice.

 The study's child-focused methodology acknowledged children’s active roles in constructing their caring roles and the social determinants which influence these. Ninety-three semi-structured interviews were conducted with children and young people with caring responsibilities, parents/relatives with HIV and service providers supporting the families in Tanzania and the UK. Participatory methods were also used with the children, including drawings, written diaries and photographs.

description: This paper studies the concept of power dissipation in infinite graphs and fractals associated with passive linear networks consisting of non-dissipative elements. In particular, we analyze the so-called Feynman-Sierpinski ladder, a fractal AC circuit motivated by Feynman's infinite ladder, that exhibits power dissipation and wave propagation for some frequencies. Power dissipation in this circuit is obtained as a limit of quadratic forms, and the corresponding power dissipation measure associated with harmonic potentials is constructed. The latter measure is proved to be continuous and singular with respect to an appropriate Hausdorff measure defined on the fractal dust of nodes of the network.

Using quantum Bayesian theory, we derive analytical expressions for the correlators, which we find to be in very good agreement with experimentally measured output signals. We further discuss how the correlators can be applied to parameter estimation, and use them to infer a small residual qubit Hamiltonian arising from calibration inaccuracy in the experimental data.

description: [Abridged] The infrared ro-vibrational emission lines from organic molecules in the inner regions of protoplanetary disks are unique probes of the physical and chemical structure of planet forming regions and the processes that shape them. The non-LTE excitation effects of carbon dioxide (CO2) are studied in a full disk model to evaluate: (i) what the emitting regions of the different CO2 ro-vibrational bands are; (ii) how the CO2 abundance can be best traced using CO2 ro-vibrational lines using future JWST data and; (iii) what the excitation and abundances tell us about the inner disk physics and chemistry. CO2 is a major ice component and its abundance can potentially test models with migrating icy pebbles across the iceline. A full non-LTE CO2 excitation model has been built. The characteristics of the model are tested using non-LTE slab models. Subsequently the CO2 line formation has been modelled using a two-dimensional disk model representative of T-Tauri disks. The CO2 gas that emits in the 15 $μ$m and 4.5 $μ$m regions of the spectrum is not in LTE and arises in the upper layers of disks, pumped by infrared radiation. The v$_2$ 15 $μ$m feature is dominated by optically thick emission for most of the models that fit the observations and increases linearly with source luminosity. Its narrowness compared with that of other molecules stems from a combination of the low rotational excitation temperature (~250 K) and the inherently narrower feature for CO2. The inferred CO2 abundances derived for observed disks are more than two orders of magnitude lower than those in interstellar ices (~10$^5$), similar to earlier LTE disk estimates. Line-to-continuum ratios are low, of order a few %, thus high signal-to-noise (S/N > 300) observations are needed for individual line detections. Prospects of accurate abundance retreival with JWST-MIRI and JWST-NIRSpec are discussed.

description: This study aimed to better understand the social worlds of older men. It sought to understand masculinity in later life, the nature of older men's social relationships, and factors influencing healthy lifestyles. A particular interest was on the lives of older men who live alone. The research objectives were:
to examine masculinity among older men by focusing on the nature of (a) family support provided to older men, (b) their involvement in social relationships with both older men and women, and (c) participation in formal, leisure and social organisations. These three types of support were examined within the context of older men's differential level of health, living arrangements and other resources

to examine how these three types of social support relationships are linked to older men's lifestyles (physical activity, smoking and drinking) and their self-assessed health and psychosocial health, focusing on how these differ for older men according to their marital status, health status, class, biography and material resources

to examine how the social relationships, health-related behaviour and psychosocial health of older men change in response to declining health status and other changed circumstances, including widowhood

to inform policy by identifying factors which may prevent or delay entry of older men into residential care, and the advisability of providing gender-segregated or gender-integrated social facilities
 Semi-structured interviews were conducted men over the age of 65 stratified according to partnership status: 30 married/remarried/cohabiting; 33 widowed; 10 divorced; and 12 never married. Further information on the study is available from the ESRC award web page.

description: Coherent many-body quantum dynamics lies at the heart of quantum simulation and quantum computation. Both require coherent evolution in the exponentially large Hilbert space of an interacting many-body system. To date, trapped ions have defined the state of the art in terms of achievable coherence times in interacting spin chains. Here, we establish an alternative platform by reporting on the observation of coherent, fully interaction-driven quantum revivals of the magnetization in Rydberg-dressed Ising spin chains of atoms trapped in an optical lattice. We identify partial many-body revivals at up to about ten times the characteristic time scale set by the interactions. At the same time, single-site-resolved correlation measurements link the magnetization dynamics with inter-spin correlations appearing at different distances during the evolution. These results mark an enabling step towards the implementation of Rydberg atom based quantum annealers, quantum simulations of higher dimensional complex magnetic Hamiltonians, and itinerant long-range interacting quantum matter.

description: We introduce a new color index consisting of two spectral band width to measure TiO absorption band strength centered at 567 nm. Based on the most up-to-date line list for TiO we regenerate a grid of synthesized spectra and investigate the temperature sensitivity of the index. The new index behave similar to older Wing TiO-index where itdecreas emonotonically from coolest atmosphere with Teff =2800 up to Teff =4000 where the TiO molecules disassociate. To further examine the feasibility of the new index we reproduce the calibration using a list of observed high resolution spectra and found similar results. This index extend TiO absorption band capability to measure effective temperature of late K to M stars to visual spectrum where it is more accessible to small telescopes for long term dedicated observation.

Multi-Choice Policing Resources for Post-Conflict Situations: Rwanda and Liberia, 2006-2007
Creators: name: Baker, B.
Publisher: name: UK Data Service
Year: 2008

description: The study examines all forms of policing in post-conflict Rwanda and Liberia, to establish the scale and nature of the various forms of policing and the manner in which they were adapting to the post-conflict environment.

 The data consists of semi-structured interview transcripts, focus groups, observation notes and images with providers of policing, users of policing and other key figures.

 The research examined:

perceptions of the public, policing agencies and state as regards the internal threats to order and security

perceptions of the security agencies, government, diplomats and donors as regards the establishment of organised crime and terrorism

the availability and effectiveness of state and non-state policing

the capacity of the two governments to provide effective state civilian policing nationwide

policy options with most potential for national internal security given the practical realities of the two post-conflict countries

 Interviews and focus groups were conducted in English in the presence of a local research colleague(s) and after permission had been granted by local government commissioners, local police commanders and local chiefs. With non-existent or unreliable voting/tax registration, random sampling proved problematic, so purposive sampling was used in interviewing users of policing (ensuring a balance between urban and rural environments, and of gender). For other data gathering, key figures were selected from those authorising and providing policing (state police agencies, commercial security, work-based security associations, youth groups and local authority security provision), and other professionals with insights into internal security and crime (government administration, commercial, legal NGOs, journalists, assembly members, jurists, academics). Every adult interviewed was told the purpose of the research, the background of the researchers and offered a summary of the findings, which was subsequently sent. They were asked for their consent in publishing their answers. All were offered anonymity but in practice very few sought it.

description: The Linac Coherent Light Source (LCLS) at Stanford Linear Accelerator Center (SLAC) is in the process of being upgraded to a superconducting radio frequency (SRF) accelerator and renamed LCLS-II. This upgrade requires thirty five 1.3 GHz SRF cryomodules (CM) and two 3.9 GHz CM. A cryogenic distribution system (CDS) is in development by Fermi National Accelerator Laboratory to interconnect the CM Linac with the cryogenic plant (CP). The CDS design utilizes cryogenic helium to support the CM operations with a high temperature thermal shield around 55 K, a low temperature thermal intercepts around 5 K, and a SRF cavity liquid helium supply and subatmospheric vapor return both around 2 K. Additionally the design must accommodate a Linac consisting of two parallel cryogenic strings, supported by two independent CP utilizing CDS components such as distribution boxes, transfer lines, feed caps and endcaps. The paper describes the overall layout of the cryogenic distribution system and the major thermodynamic factors which influence the CDS design including heat loads, pressure drops, temperature profiles, and pressure relieving requirements. In addition the paper describes how the models are created to perform the analyses.

description: Formation of dressed light-matter states in optical structures, manifested as Rabi splitting of the eigen energies of a coupled system, is one of the key effects in quantum optics. In pursuing this regime with semiconductors, light is usually made to interact with excitons $-$ electrically neutral quasiparticles of semiconductors, meanwhile interactions with charged three-particle states $-$ trions $-$ have received little attention. Here, we report on strong interaction between plasmons in silver nanoprisms and charged excitons $-$ trions $-$ in monolayer tungsten disulphide (WS$_{2}$). We show that the plasmon-exciton interactions in this system can be efficiently tuned by controlling the charged versus neutral exciton contribution to the coupling process. In particular, we show that a stable trion state emerges and couples efficiently to the plasmon resonance at low temperature by forming three bright intermixed plasmon-exciton-trion polariton states. Our findings open up a possibility to exploit electrically charged trion polaritons $-$ previously unexplored mixed states of light and matter in nanoscale hybrid plasmonic systems.
