description: We present 2D-spectroscopic observations from Centro Astronómico Hispano Alemán (CAHA) 3.5 m telescope and the millimetre observation from NOrthern Extended Millimeter Array (NOEMA) of the nearby S0 galaxy PGC 26218, which shows central star-formation activity and post-starburst outside in the disk. We estimate the star formation rate (SFR = $0.28\pm0.01$ $M_{\odot} \rm yr^{-1}$) and molecular gas mass ($\rm log\ $$M_{\rm H_{2}}=7.60\pm0.15\ M_{\odot}$) of PGC 26218 based on the extinction-corrected H$α$ emission line and the CO-$\rm H_{2}$ conversion factor ($α_{\rm CO}$) of the Milky Way, respectively. We find that PGC 26218 follows the star forming main sequence (SFMS) and the Kennicutt-Schmidt law. Comparing the kinematics of CO($J$=1-0), stars and H$α$, we find that the rotational axis of CO($J$=1-0) is 45$^{\circ}$ different from that of H$α$. In addition, the profile of the CO($J$=1-0) emission line shows asymmetry and has an inflow component of $\sim$ 46 $\rm km\ s^{-1}$. With the decomposition of the optical image, we confirm that PGC 26218 shows multiple nuclear structures. The projected offset between the most luminous optical center and the center of CO($J$=1-0) is $5.2\arcsec$ ($\sim$ 0.6 kpc) and the latter overlaps with one of the optical cores. These results support that PGC 26218 may have experienced a gas-rich minor merger, extending its star formation and locating it in the SFMS.

Relativistic description of the np to eta d reaction near threshold

description: Relativistic effects in a three-body calculation of the $np\toηd$ process are considered. Relativistic effects on the range and strength of the pion exchange contribution to the reaction mechanism may be large, but boost effects of the two-body interactions are negligible. The relativistic calculation confirms previous non-relativistic results, showing that the shape of the cross section near threshold is essentially determined by the $ηd$ final-state interaction alone. As for the region away from threshold, the relativistic pion exchange contribution is seen to dominate the other mechanisms of the reaction. It turns out that, within the relativistic reaction model, the $np\toηd$ experimental data excludes large values for the real part of the $ηN$ scattering length.

description: We analyze the topological superconductivity and investigate the spectroscopic properties manifested by the zero-energy modes, induced in a metallic strip embedded into a Josephson-type junction. Focusing on the Majorana polarization of such quasiparticles, we propose feasible means for its empirical detection, using the spin-selective Andreev reflection method. Our study reveals a gradual development of a transverse gradient of the Majorana polarization across the metallic strip upon increasing its width. We also inspect the spatial profile and polarization of the Majorana quasiparticles in the presence of a strong electrostatic impurity. We show that, depending on its position, such a defect can lead to a substantial localization of the Majorana mode.

description: The project video highlights key elements and messages to potential audiences, and for promoting the BD4OPEM H2020 project to a wider audience. It ensured that all project stakeholders were made aware of the project scope, direction and results, and maintained momentum and engagement during the project. It acted as a trailer to the second video produced at the end of 2021. Due to (travel) restrictions imposed by the Covid pandemic, there was change in strategy; a first short introductory video in English was produced (M14) presenting the key project elements and guiding the viewer to our website for more information. The video was then localised (M15) and was available in seven project relevant languages represented by partners. The English version of the video has been uploaded to the project website. Each partner is encouraged to use it in their own marketing activities or when presenting the BD4OPEM H2020 project to local stakeholders. Once Covid related restrictions are lifted, two further videos are planned M18 and M42 with clips from pilot sites and interviews with stakeholders to demonstrate the range of impacts of the eighteen BD4OPEM services developed on energy distribution networks.

description: This project investigates the power of ritual and infrastructure at the US-Mexico border, where thousands of asylum seekers have overwhelmed an ill-equipped immigration system and are forced to wait in Mexico for months for the opportunity to present themselves at a port of entry. Operating within the realities of sheltering and processing large volumes of people the project navigates between several tensions: utopia and dystopia, tradition and modernity, human and machine, freedom and confinement. Set in the bi-national conurbation of El Paso and Ciudad Juarez, the project juggles the competing goals of the actors in the region to propose an infrastructure that facilitates rituals for the passage of time and rituals for the passage of people over the border.
Reinterpreting $pp \to W^+W^-$ searches for charginos

description: The hallmark way to search for electroweakinos in natural supersymmetry at the LHC involves the trilepton plus missing energy final state. This approach assumes an electroweakino mass hierarchy that allows for cascade decays leading to a final state of $W^{\pm}Z^0$ plus missing energy. There are, however, situations when that decay pattern may not exist, such as when a chargino is the lightest electroweakino and the lightest supersymmetric particle is the gravitino. In regions of the parameter space where this ordering occurs, the production of any combination of neutralino/chargino leads to a $W^+W^- + X$ plus missing energy final state, where $X$ could be additional jets or leptons. If $X$ is soft, then all neutralino/chargino production modes fall into the same experimental final state, dileptons plus missing energy. ATLAS and CMS have leptonic $W^+W^-$ plus missing energy searches, but their interpretation assumes a spectrum consisting of an isolated charged state. In this paper, we identify the circumstances under which natural supersymmetry models can avoid $W^{\pm}Z^0$ plus missing energy bounds. For scenarios that escape $W^{\pm}Z^0$ plus missing energy, we then recast the latest ATLAS $W^+W^-$ plus missing energy search, taking into account all the states that contribute to the same signal. Assuming the lightest supersymmetric particle is massless, we find a bound of 460 GeV for a higgsino-like degenerate doublet. Finally, we extend our arguments to a non-supersymmetric simplified model containing new electroweak-scale $SU(2)_w$ doublets and singlets.

description: The wide adoption of multimedia service capable mobile devices, the availability of better networks with higher bandwidths, and the availability of platforms offering digital content has led to an increasing popularity of multimedia streaming services. However, multimedia streaming services can be subject to different factors that affect the quality perceived by the users, such as service interruptions or quality oscillations due to changing network conditions, particularly in mobile networks. Dynamic Adaptive Streaming over HTTP (DASH), leverages the use of content-distribution networks and the capabilities of the multimedia devices to allow multimedia players to dynamically adapt the quality of the media streaming to the available bandwidth and the device characteristics. While many elements of DASH are standardized, the algorithms providing the dynamic adaptation of the streaming are not. The adaptation is often based on the estimation of the throughput or a buffer control mechanism. In this paper, we present a new throughput estimation adaptation algorithm based on a statistical method named Adaptive Forgetting Factor (AFF). Using this method, the adaptation logic is able to react appropriately to the different conditions of different types of networks. A set of experiments with different traffic profiles show that the proposed algorithm improves video quality performance in both wired and wireless environments.

title: A qualitative study looking at the experience of mothers with learning disabilities and their school aged children.
Creators: name: Edmonds, Jane C.
Publisher: name: The Open University
Year: 1998

description: This study looked at the experiences of mothers with learning disabilities and their school aged children. The participants comprised a) 8 mothers with learning disabilities, with school aged children (5-18 years old), who had received services from a community team for people with learning disabilities, and b) 4 children from these families whose permission had been obtained to participate. In-depth, semi-structured interviews were conducted to explore the experiences of the mothers and children in relation to key aspects of family life and the psychological consequences of these experiences. Grounded theory was used to analyse the text generated from the interviews. Findings suggested the importance of identity, difficult relationship and attachment styles, psychological vulnerability and lack of control. This led to a formulation of how different aspects of die mother's and children's experiences interact to produce the overall experience for this group. The model tentatively suggests an interaction between external factors (poverty, support networks, life events) and factors within the individual (role identity, lack of control, attachment patterns and vulnerability) which results in psychological distress and need for support. The model is expanded and validated via recourse to existing theory, namely social identity theory (Tajfel, 1981) attachment (Bowlby, 1969) and object relations theory (Guntrip, 1971), a life events model (Brown and Harris, 1978) and a model of locus of control (Cohen, 1980). The findings are evaluated and ideas for future research are discussed. Clinical implications are also addressed.

description: The process of protein synthesis in biological systems resembles a one dimensional driven lattice gas in which the particles (ribosomes) have spatial extent, covering more than one lattice site. Realistic, nonuniform gene sequences lead to quenched disorder in the particle hopping rates. We study the totally asymmetric exclusion process with large particles and quenched disorder via several mean field approaches and compare the mean field results with Monte Carlo simulations. Mean field equations obtained from the literature are found to be reasonably effective in describing this system. A numerical technique is developed for computing the particle current rapidly. The mean field approach is extended to include two-point correlations between adjacent sites. The two-point results are found to match Monte Carlo simulations more closely.

description: We propose and demonstrate a nonlinear optics approach to emulate Ising machines containing up to a million spins and with tailored two and four-body interactions with all-to-all connections. It uses a spatial light modulator to encode and control the spins in the form of the binary phase values of wavelets in coherent laser beams, and emulates the high-order interaction with frequency conversion in a nonlinear crystal at the Fourier plane. By adaptive feedback control, the system can be evolved into effective spin configurations that well approximate the ground states of Ising Hamiltonians with all-to-all connected many-body interactions. Our technique could serve as a new tool to probe complex, many-body physics and give rise to exciting applications in big data optimization, computing, and analytics.

We include analytic expressions for the contributions of gluinos, neutralinos and charginos. We obtain general constraints on off-diagonal mass terms between the first two generations of both down-type and up-type squarks. In the down-squark sector, we compare the results with gluino-only estimates. In the up-squark sector, we find a complete set of bounds on all combinations of chirality conserving or chirality flipping parameters. Finally, we comment on the size of the bounds obtained by imposing left-right symmetry in the squark sector.

description: We investigate the generation of features at large scales in the primordial power spectrum (PPS) when inflation is driven by two scalar fields. In canonical single field models of inflation, these features are often generated due to deviations from the slow-roll regime. While deviations from slow-roll can be naturally achieved in two field models due to a sharp turn in the trajectory in the field space, features at the largest scales of the types suggested by CMB temperature anisotropies are more difficult to achieve in models involving two canonical scalar fields due to the presence of isocurvature fluctuations. We show instead that a coupling between the kinetic terms of the scalar fields can easily produce such features. We discuss models whose theoretical predictions are consistent with current observations and highlight the implications of our results.

description: We study the Josephson-like spin currents between two ferromagnetic metals by deriving the effective action of the junction. A DC spin Josephson current with the full O(3) symmetry is obtained. By the analogy to the superconducting junctions, we have shown that a time-independent uniform magnetic field can serve as the source of the AC spin Josephson effect. That is, the spin current becomes a periodic function of the time with the period proportional to the inverse of the magnitude of the external magnetic field.

description: Recent analyses of solar photospheric abundances suggest that the oxygen abundance in the solar atmosphere needs to be revised downwards. In this study we investigate the consequence of this revision on helioseismic analyses of the depth of the solar convection zone and the helium abundance in the solar envelope and find no significant effect. We also find that the revised abundances along with the current OPAL opacity tables are not consistent with seismic data. A significant upward revision of the opacity tables is required to make solar models with lower oxygen abundance consistent with seismic observations.

description: We study the behaviour of linear and nonlinear spectroscopic quantities in two-dimensional topologically ordered systems, which host anyonic excitations exhibiting fractional statistics. We highlight the role that braiding phases between anyons have on the dynamics of such quasiparticles, which as we show dictates the behaviour of both linear response coefficients at finite temperatures, as well as nonlinear pump-probe response coefficients. These quantities, which act as probes of temporal correlations in the system, are shown to obey distinctive universal forms at sufficiently long timescales. As well as providing an experimentally measurable fingerprint of anyonic statistics, the universal behaviour that we find also demonstrates anomalously fast thermal relaxation: correlation functions decay as a `squished exponential' $C(t) \sim \exp(-[t/τ]^{3/2})$ at long times. We attribute this unusual asymptotic form to the nonlocal nature of interactions between anyons, which allows relaxation to occur much faster than in systems with quasiparticles interacting via local, non-statistical interactions. While our results apply to any Abelian or non-Abelian topological phase in two-dimensions, we discuss in particular the implications for candidate quantum spin liquid materials, wherein the relevant quantities can be measured using pre-existing time-resolved terahertz-domain spectroscopic techniques.

title: Understanding the Factors Which Influence Learning disability Direct Care Staff to Spend Time in 'Focused 1:1 Work' With Clients: An Application of the Theory of Planned Behaviour
Creators: name: Flecknoe, Paul
Publisher: name: The Open University
Year: 1998

description: This study aimed to examine the factors that influence learning disability care staff to spend time with clients that is focused on their developmental needs, rather than the routine, custodial tasks of care. This type of individualised time is defined for the study as time spent in "focused 1:1 work* with clients, and a detailed definition is developed. The value of time spent individually with clients is considered in relation to current service philosophies, the understanding of challenging behaviour and in terms of the satisfaction that staff derive from this aspect of their work. The theory of planned behaviour is suggested as a framework within which this issue can be investigated. It is noted that this study constitutes the application of the theory to a repeated behaviour, which has specific associated methodological issues. A questionnaire, based on the theory of planned behaviour, was developed, to try and understand the Actors that might predict staff members' intentions and behaviour as regards spending time in focused 1:1 work with clients. In addition, a measure of job satisfaction was included to assess the previously reported relationship between client-centred aspects of care work and job satisfaction. Overall, results indicated that perceived behavioural control was the most important factor in understanding time allocation to this activity. This variable accounted for 35 percent of the variance in behavioural intention. The implications of this result in terms of interventions involving learning disability staff and service development are considered. Possibilities for future research are outlined.

The abrupt change of the electric field gradient at the Cl sites, as well as the sizable change of the lattice constants, across the phase boundary indicate that the magnetic order is accompanied by simultaneous lattice deformation.

description: The aim of this paper is to investigate the numerical implementation of the Field Dislocation Mechanics (FDM) theory for the simulation of dislocation-mediated plasticity. First, the mesoscale FDM theory of Acharya and Roy (2006) is recalled which permits to express the set of equations under the form of a static problem, corresponding to the determination of the local stress field for a given dislocation density distribution, complemented by an evolution problem, corresponding to the transport of the dislocation density. The static problem is solved using FFT-based techniques (Brenner et al., 2014). The main contribution of the present study is an efficient numerical scheme based on high resolution Godunov-type solvers to solve the evolution problem. Model problems of dislocation-mediated plasticity are finally considered in a simplified layer case. First, uncoupled problems with uniform velocity are considered, which permits to reproduce annihilation of dislocations and expansion of dislocation loops. Then, the FDM theory is applied to several problems of dislocation microstructures subjected to a mechanical loading.

description: Located on the East shore of Victoria BC Upper Harbour, the Rock Bay Industrial District—the Workshop of the City—is home to a critical reservoir of living income employment, businesses and services essential to the economic health and resilience of the City. Extreme land shortage, paired with aged low-density building stock and high property taxes, have contributed to an affordability crisis threatening viability of the area. The impacts are wide reaching: forcing anchor businesses to migrate regionally, depleting the area’s diversity and development confidence. This highly constrained environment places enormous pressure on small businesses to maintain viability for the area, resulting in inflation, renovictions, and potential large-scale future rezoning.

description: We present the ASCA results of intermediate-mass pre-main-sequence stars (PMSs), or Herbig Ae/Be stars (HAeBes). Among the 35 ASCA pointed-sources, we detect 11 plausible X-ray counterparts. X-ray luminosities of the detected sources in the 0.5-10 keV band are in the range of log LX ~30-32 ergs s-1, which is systematically higher than those of low-mass PMSs. This fact suggests that the contribution of a possible low-mass companion is not large. Most of the bright sources show significant time variation, particularly, two HAeBes - MWC 297 and TY CrA - exhibit flare-like events with long decay timescales (e-folding time ~ 10-60 ksec). These flare shapes are similar to those of low-mass PMSs. The X-ray spectra are successfully reproduced by an absorbed one or two-temperature thin-thermal plasma model. The temperatures are in the range of kT ~1-5 keV, which are significantly higher than those of main-sequence OB stars (kT < 1 keV). These X-ray properties are not explained by wind driven shocks, but are more likely due to magnetic activity. On the other hand, the plasma temperature rises as absorption column density increases, or as HAeBes ascend to earlier phases. The X-ray luminosity reduces after stellar age of a few x10^6 years. X-ray activity may be related to stellar evolution. The age of the activity decay is apparently near the termination of jet or outflow activity. We thus hypothesize that magnetic activity originates from the interaction of the large scale magnetic fields coupled to the circumstellar disk. We also discuss differences in X-ray properties between HAeBes and main-sequence OB stars.

description: Recently Hertog, Horowitz, and Maeda (HHM) (hep-th/0310054) have proposed that cosmic censorship can be violated in the AdS/CFT context. They argue that for certain initial data there is insufficient energy available to make a black hole whose horizon is big enough to cloak the singularity that forms. We have investigated this proposal in the models HHM discuss and have thus far been unable to find initial data that provably satisfy this criterion, despite our development of an improved lower bound on the size of the singular region. This is consistent with recent numerical results (hep-th/0402109). For certain initial data, the energies of our configurations are not far above the lower bound on the requisite black hole mass, and so it is possible that in the exact time development naked singularities do form. We go on to argue that the finite radius cut-off AdS_5 situation discussed by HHM displays instabilities when the full 10D theory is considered. We propose an AdS_3 example that may well be free of this instability.

description: Direct economic impacts of flooding are essential for flood mitigation policies, and are based upon multiple tools, among which 2D hydrodynamic models. These models are dependent on multiple parameters and data, such as topography, and can yield considerably different results depending on their values, ultimately changing the resultant damage estimation. To help in understanding some of the underlying drivers of this variation, this conference paper compares damage estimations issued by two different hydrodynamic models of the Garonne River, near Marmande, in France. The influence of a topo-bathymetry projection method, which aims at reducing some interpolation incoherencies, was also studied. The general conclusion is that these two factors, i.e., a change in the model parameters and the topo-bathymetry projection method, do matter but their influence on the total cost estimation is highly dependent on the description of a few high-vulnerability agricultural fields. Indeed, the latter often account for the majority of the total damage even if occupying a fraction of the total area. This paper then advocates for a more vulnerability-based modelling approach, with a focus on the few high-vulnerability areas.

description: The Rural Income Maintenance Experiment was the second of four major experiments to test the behavioral consequences of a universal income-conditioned cash transfer program. It followed closely its predecessor, the New Jersey Income Maintenance Experiment, in objectives and design. Of the four experiments, its principal uniqueness is that it is the only one focusing on the rural sector (farmers and those in towns of less than 2500).

description: Deep learning provide successful applications in many fields. Recently, machines learning are involved for oceans remote sensing applications. In this study, we use and compare about eight (8) deep learning estimators for retrieval of a mainly pigment of phytoplankton. Depending on the water case and the multiple instruments simultaneouslyobserving the earth on a variety of platforms, several algorithm are used to estimate the chlolophyll-a from marine reflectance. By using a long-term multi-sensor time-series of satellite ocean-colour data, as MODIS, SeaWifs, VIIRS, MERIS, etc, we make a unique deep network model able to establish a relationship between sea surface reflectance and chlorophyll-a from any measurement satellite sensor over West Africa. These data fusion take into account the bias between case water and instruments. We construct several chlorophyll-a concentration prediction deep learning based models, compare them and therefore use the best for our study. Results obtained for accuracy training and test are quite good. The mean absolute error are very low and vary between 0,07 to 0,13 mg/m3.

description: Mt. Abu Faint Object Spectrograph and Camera (MFOSC-P) is an in-house developed instrument for Physical Research Laboratory (PRL) 1.2m telescope at Mt. Abu India, commissioned in February 2019. Here we present the first science results derived from the low resolution spectroscopy program of a sample of M Dwarfs carried out during the commissioning run of MFOSC-P between February-June 2019. M dwarfs carry great significance for exoplanets searches in habitable zone and are among the promising candidates for the observatory's several ongoing observational campaigns. Determination of their accurate atmospheric properties and fundamental parameters is essential to constrain both their atmospheric and evolutionary models. In this study, we provide a low resolution (R$\sim$500) spectroscopic catalogue of 80 bright M dwarfs (J$

description: We analyze the effects of an electron-phonon interaction on the one-electron spectral weight A(k,omega) of a d_{x^2-y^2} superconductor. We study the case of an Einstein phonon mode with various momentum-dependent electron-phonon couplings and compare the structure produced in A(k,omega) with that obtained from coupling to the magnetic pi-resonant mode. We find that if the strength of the interactions are adjusted to give the same renormalization at the nodal point, the differences in A(k,omega) are generally small but possibly observable near k=(pi,0).

description: In a recently suggested method for measuring the weak phase $γ$ in $B^\pm \to K^\pm (KK^*)_D$ decays, the relative strong phase $δ_D$ in $D^0 \to K^{*+} K^-$ and $D^0 \to K^{*-} K^+$ decays (equivalently, in $D^0 \to K^{*+} K^-$ and $\od \to K^{*+} K^-$) plays a role. It is shown how a study of the Dalitz plot in $D^0 \to K^+ K^- π^0$ can yield information on this phase, and the size of the data sample which would give a useful measurement is estimated.

FEDERAL REGULATION OF FRUIT AND VEGETABLE INDUSTRIES

Year: 1977
Subjects: Crop Production/Industries

description: In early 1977, the Economic Research Service initiated a study of the impact of Federal regulations affecting production, processing and distribution of fruits and vegetables. Impetus for the study came from a resource reallocation scheme in ERS for fiscal 1977 which redirected research manpower and dollars according to perceived emerging issues. Christened the "five percent plan," it involved the ERS divisions pooling 5 percent of their resources and then "bidding" for these pooled resources by submitting research proposals. A proposal for a general study of regulations as they affect agriculture ranked high on the list of researchable emerging issues. A commodity approach was recommended with fruits and vegetables ultimately selected as a prototype subsector. The focus of the study was narrowed to Federal regulatory activity because of the large number and diversity of state and local regulations, particularly in the produce industry. Four SMY's and $100,000 were initially allocated to the project. In addition, program areas in ERS not directly assigned a part in the study but having an interest in regulatory activity were encouraged to informally participate. This paper will be followed by a discussion of a complementary ERS study of this type.
