description: We report here on initial results from the Thousand Pulsar Array (TPA) programme, part of the Large Survey Project "MeerTime" on the MeerKAT telescope. The interferometer is used in tied-array mode in the band from 856 to 1712~MHz, and the wide band coupled with the large collecting area and low receiver temperature make it an excellent telescope for the study of radio pulsars. The TPA is a 5 year project which aims to observe (a) more than 1000 pulsars to obtain high-fidelity pulse profiles, (b) some 500 of these pulsars over multiple epochs, (c) long sequences of single-pulse trains from several hundred pulsars. The scientific outcomes from the programme will include determination of pulsar geometries, the location of the radio emission within the pulsar magnetosphere, the connection between the magnetosphere and the crust and core of the star, tighter constraints on the nature of the radio emission itself as well as interstellar medium studies. First results presented here include updated dispersion measures, 26 pulsars with Faraday rotation measures derived for the first time and a description of interesting emission phenomena observed thus far.

description: The Unhanding is a collection of poems in response to loss and the empty spaces it leaves behind. The collection leans on ekphrastic poems based on the visual art of Mark Rothko and others as a means of contributing to the narrator’s journey of sense-making in the face of various kinds of loss. The first section responds to the decline and deaths of older parents and middle-aged friends, miscarriage, the changing seasons of parenthood and friendship, and threats to our well-being. In the next section, poems present responses of anxiety and movement through time and space. The final section acknowledges loss but also renewed discoveries of domestic life, relationships, and fulfilling possibilities. The Unhanding speaks not only to a literal letting-go of physical life, but a letting-go of the angst that keeps a survivor from employing the empty spaces to move forward—and a surrender to what comes next.

description: Background and Objective: In the current study, we sought to determine the value of a meta-analysis to improve decision-making processes related to nutrition in the poultry industry. To this end, nine commercial size experiments were conducted to test the effect of a phytogenic feed additive and three approaches were applied to the data. Materials and Methods: In all experiments, 1-day-old male Cobb 500 chicks were used and fed corn-soybean meal diets. Two dietary treatments were tested: T1, control diet and T2, control diet + feed additive at a 0.05% inclusion rate. The experimental units were broiler houses (7 experiments), floor pens (1 experiment) and cages (1 experiment). The response variables were final body weight, feed intake, feed conversion ratio, mortality and production efficiency. Analyses of variance of data from each and all the experiments were performed using SAS under completely randomized non-blocked or blocked designs, respectively. The meta-analyses were performed in R programming language. Results: No statistically significant effects were found in the evaluated variables in any of the independent experiments (p>0.12), nor following the application of a block design (p>0.08). The meta-analyses showed no statistically significant global effects in terms of final body weight (p>0.19), feed intake (p>0.23), mortality (p>0.09), or European Production Efficiency Factor (p>0.08); however, a positive global effect was found with respect to feed conversion ratio (p<0.046). Conclusion: This meta-analysis demonstrated that the phytogenic feed additive improved the efficiency of birds to convert feed to body weight (35 g less feed per 1 kg of body weight obtained). Thus, the use of meta-analyses in commercial-scale poultry trials can increase statistical power and as a result, help to detect statistical differences if they exist.
Can the galactic rotation curves be explained in brane world models?

description: We consider solutions with conformal symmetry of the static, spherically symmetric gravitational field equations in the vacuum in the brane world scenario. By assuming that the vector field generating the symmetry is non-static, the general solution of the field equations on the brane can be obtained in an exact parametric form, with the conformal factor taken as parameter. As a physical application of the obtained solutions we consider the behavior of the angular velocity of a test particle moving in a stable circular orbit. In this case the tangential velocity can be expressed as a function of the conformal factor and some integration constants only. For a specific range of the integration constants, the tangential velocity of the test particle tends, in the limit of large radial distances, to a constant value. This behavior is specific to the galactic rotation curves, and is explained usually by invoking the hypothesis of the dark matter. The limiting value of the angular velocity of the test particle can be obtained as a function of the baryonic mass and radius of the galaxy. The behavior of the dark radiation and dark pressure terms is also considered in detail, and it is shown that they can be expressed in terms of the rotational velocity of a test particle. Hence all the predictions of the present model can be tested observationally. Therefore the existence of the non-local effects, generated by the free gravitational field of the bulk in a conformally symmetric brane, may provide an explanation for the dynamics of the neutral hydrogen clouds at large distances from the galactic center.

description: Background and Objective: Several studies confirm that the age of hens has a tremendous impact on external and internal egg quality characteristics. Egg production could be at serious risk if egg quality characteristics and age of hens are not seriously considered. This study was conducted to analyze the phenotypic correlations between some internal and external egg quality characteristics in old laying hens. Materials and Methods: A total of 288 eggs of 85-week-old Hy-Line Brown laying hens were collected during 3 weeks and their internal and external egg characteristics were evaluated. Results: Phenotypic correlations between egg quality characteristics in old laying hens indicate a negative impact on shell and albumen quality but not affected yolk quality characteristics. Conclusion: This study helps to understand that raising laying hens above 80 weeks would have a negative impact on egg quality characteristics.

Lectotypus (designated by JESSOP, 1976: 411): (Houttuyn, Nat. Hist. II(12): tab. 85, fig. 1. 1780).
Epitypus (designated here by Callmander & Veldkamp): SOUTH AFRICA: Cape, Thunberg s.n. (UPS-THUNB n° 7991 image seen).
Notes. – The genus Massonia Thunb. ex Houtt. was described by Houttuyn in Natuurlijke Historie (Nat. Hist. II(12): 424. 1780), with M. depressa listed as the only species. The description was based on “A Cape plant recently from the Hortus medicus of this place [Amsterdam] thus named by Mr. Thunberg”. The illustration shows two flowers, which were given to him by its Curator Johannes Storm in 1779. Thunberg was paid by the Hortus for sending seeds and bulbs. No specimen of Massonia has been found in the Houttuyn herbarium in G-PREL. The illustration by Houttuyn must therefore be considered to be the type.
Massonia Thunb. ex L. f. (LINNAEUS f., IV.1782: 27, 193) and Massonia Thunb. (THUNBERG, 10.VII.1782: 39) are later homonyms.
Massonia latifolia L. f. (and Thunb.) is based on a Masson collection that has never been located (LINNAEUS f., 1782: 193; THUNBERG, 1782: 40; see JESSOP, 1976: 410-412). This species is now widely considered to be a synonym of the earlier M. depressa. JESSOP (1976: 411) only found fruiting material at UPS-THUNB and implicitly designated Houttuyn’s plate of flowers as the lectotype. A Thunberg flowering collection in UPS-THUNB, located by M. Hjertson (UPS), is designated here as the epitype.

description: Environmental temperature (ET) often changes the nutrient intake/output for layers. Changing feed formulations based on ET may need to be utilized to obtain optimum performance, shell quality and bone status. This study was conducted to investigate the effects of temperature, Ca intake, non-phytate P (NPP) intake and in vitro limestone solubility (LS) on egg-shell quality and bone status in commercial White Leghorn hens. Egg mass and shell weight per unit surface area (SWUSA) decreased with increasing ET (p lower than 0.05), especially when ET was 29.7 C (cycling mean ET)or a constant ET was 32.2 C. Feeding layers a low soluble larger particle size limestone instead of a highly soluble limestone produced beneficial effects for SWUSA at the thermoneutral ET (21.1 C) but the beneficial effect was less or disappeared when ET was higher than 26.6 C in EXP 1 and 2. Feeding layers 245 and 353 mg NPP/h/d supported satisfactory bone status at 21.1 C, however layers housed at higher than 30 C needed an additional intake of 50 mg NPP/h/d to support bone integrity. Results of EXP 1 and 2 indicates that 48 week old layers housed in thermoneutral or warmer ET require a minimum of 4.2 g Ca/h/d for maintaining optimum shell quality and bone integrity. Feeding low LS (34.1% in vitro solubility) improved egg shell quality only for hens housed in thermoneutral ET (21.1 C) and did not improve egg shell quality at higher ET (constant or cycling). Daily NPP intake of 245 and 353 mg/h/d supported optimum egg production and bone status at 21.1 C, respectively. A higher NPP and Ca intake may be required for bone status compared to egg production, especially in older hens.

description: We present experimental results and theoretical analysis of the diffuse reflection of a Bose-Einstein condensate from a rough mirror. The mirror is produced by a blue-detuned evanescent wave supported by a dielectric substrate. The results are carefully analysed via a comparison with a numerical simulation. The scattering is clearly anisotropic, more pronounced in the direction of the evanescent wave surface propagation, as predicted theoretically.

description: Genus Viaphacops Maximova, 1972
 TYPE SPECIES: Phacops pipa Hall and Clarke, 1888; early Middle Devonian of North America (New York State, Michigan and Southern Ontario).
GENERIC DIAGNOSIS (Maximova, 1972): Preoccipital lobe entirely reduced; preoccipital furrow merged with occipital furrow to form a deep broad furrow on site of preoccipital lobe. Occipital ring usually narrow. Vincular furrow deep, with prominent inner border. Eyes of moderate size, less frequently large. Pygidium usually wide, weakly segmented. Surface of glabella with fairly large nodes.
 SYSTEMATIC NOTE: Those phacopids that were originally placed in the genus Phacops from Central Kazakhstan and the Far Eastern part of the former Soviet Union were reexamined by Maximova (1972), who erected a new genus, Paciphacops, with two subgenera, P. (Paciphacops) and P. (Viaphacops), each containing several species. Elsewhere Viaphacops has been elevated to generic rank (e.g., Ramsköld and Werdelin, 1991; Linsley, 1994) and that practice is also followed here.

Measurement of azimuthal anisotropy of muons from charm and bottom hadrons in Pb+Pb collisions at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV with the ATLAS detector

description: Azimuthal anisotropies of muons from charm and bottom hadron decays are measured in Pb+Pb collisions at $\sqrt{s_\mathrm{NN}}= 5.02$ TeV. The data were collected with the ATLAS detector at the Large Hadron Collider in 2015 and 2018 with integrated luminosities of $0.5~\mathrm{nb}^{-1}$ and $1.4~\mathrm{nb^{-1}}$, respectively. The kinematic selection for heavy-flavor muons requires transverse momentum $4 < p_\mathrm{T} < 30$ GeV and pseudorapidity $|η|<2.0$. The dominant sources of muons in this $p_\mathrm{T}$ range are semi-leptonic decays of charm and bottom hadrons. These heavy-flavor muons are separated from light-hadron decay muons and punch-through hadrons using the momentum imbalance between the measurements in the tracking detector and in the muon spectrometers. Azimuthal anisotropies, quantified by flow coefficients, are measured via the event-plane method for inclusive heavy-flavor muons as a function of the muon $p_\mathrm{T}$ and in intervals of Pb+Pb collision centrality. Heavy-flavor muons are separated into contributions from charm and bottom hadron decays using the muon transverse impact parameter with respect to the event primary vertex. Non-zero elliptic ($v_{2}$) and triangular ($v_{3}$) flow coefficients are extracted for charm and bottom muons, with the charm muon coefficients larger than those for bottom muons for all Pb+Pb collision centralities. The results indicate substantial modification to the charm and bottom quark angular distributions through interactions in the quark-gluon plasma produced in these Pb+Pb collisions, with smaller modifications for the bottom quarks as expected theoretically due to their larger mass.

description: This paper introduces an innovative physics-informed deep learning framework for metamodeling of nonlinear structural systems with scarce data. The basic concept is to incorporate physics knowledge (e.g., laws of physics, scientific principles) into deep long short-term memory (LSTM) networks, which boosts the learning within a feasible solution space. The physics constraints are embedded in the loss function to enforce the model training which can accurately capture latent system nonlinearity even with very limited available training datasets. Specifically for dynamic structures, physical laws of equation of motion, state dependency and hysteretic constitutive relationship are considered to construct the physics loss. In particular, two physics-informed multi-LSTM network architectures are proposed for structural metamodeling. The satisfactory performance of the proposed framework is successfully demonstrated through two illustrative examples (e.g., nonlinear structures subjected to ground motion excitation). It turns out that the embedded physics can alleviate overfitting issues, reduce the need of big training datasets, and improve the robustness of the trained model for more reliable prediction. As a result, the physics-informed deep learning paradigm outperforms classical non-physics-guided data-driven neural networks.

description: Following the recent research enthusiasm on the effect of geometry on near-field heat transfer (NFHT) enhancement, we present an analysis based on simplified yet highly efficient graphene and nanotube models. Two geometries are considered: that of two parallel infinite "graphene" surfaces and that of a one-dimensional infinite "nanotube" line in parallel with an infinite surface. Due to its symmetry, the former is in principal simpler to analyze and even so, earlier works suggested that the application of a full model in this problem still demands heavy computations. Among other findings, our simplified computation - having successfully replicated the results of relevant earlier works - suggests a sharper NFHT enhancement dependence on distance for the line-surface system, namely $J\sim d^{-5.1}$ as compared to $J\sim d^{-2.2}$ for the parallel surface. Such comparisons together with applications of our efficient approach would be the important first steps in the attempt to find a general rule describing geometric dependence of NFHT.

description: Undercapitalization has been recognized as a problem affecting Italian co-operatives to perform in modern agri-food markets. An empirical study on 50 Italian agri-food co-operatives was carried out to investigate co-operatives members’ commitment capability to impact on the level of capitalization. The level of capitalization was also investigated as a mean to influence co-operatives’ innovation and subsequently their performance. The results show how co-operatives with more committed memberships display higher levels of capitalization and that capitalization positively relates with innovation levels. The latter is also confirmed to enhance co-operatives’ performance. These results are relevant from a managerial point of view as they reveal the importance of members’ commitment in this particular type of organizations and provide new insights to improve co-operatives’ innovation and performance.

description: This study analyses technical efficiency (TE) levels among small-scale raspberry producers in Central Chile. Special attention is given in to investigate the impact of the marketing channel used by the farmers on their technical performance. The data used in this study were obtained from a farm-level survey of 139 small-scale raspberry farmers. A stochastic production frontier model was used to evaluate the association between TE, extension, training and farmers’ decisions to sell their production directly to the agro-industry or indirectly through an informal middleman. The empirical results show that the decision to sell raspberries using informal channels is negatively associated with farm productivity and revenues. The analysis also reveals a positive relationship between TE and income among experienced and trained farmers. Implementing food quality and safety standards was also found decisive in increasing farm income. Policy implications stemming from these results are also discussed.

description: Level set-based immersed boundary techniques operate on nonconforming meshes while providing a crisp definition of interface and external boundaries. In such techniques, an isocontour of a level set field interpolated from nodal level set values defines a problem's geometry. If the interface is explicitly tracked, the intersected elements are typically divided into sub-elements to which a phase needs to be assigned. Due to loss of information in the discretization of the level set field, certain geometrical configurations allow for ambiguous phase assignment of sub-elements, and thus ambiguous definition of the interface. The study presented here focuses on analyzing these topological ambiguities in embedded geometries constructed from discretized level set fields on hexahedral meshes. The analysis is performed on three-dimensional problems where several intersection configurations can significantly affect the problem's topology. This is in contrast to two-dimensional problems where ambiguous topological features exist only in one intersection configuration and identifying and resolving them is straightforward. A set of rules that resolve these ambiguities for two-phase problems is proposed, and algorithms for their implementations are provided. The influence of these rules on the evolution of the geometry in the optimization process is investigated with linear elastic topology optimization problems. These problems are solved by an explicit level set topology optimization framework that uses the extended finite element method to predict physical responses. This study shows that the choice of a rule to resolve topological features can result in drastically different final geometries. However, for the problems studied in this paper, the performances of the optimized design do not differ.
Turning Public into Private Participation in GCC States' Infrastructure: Sustainable Institutions in a World of International Investment Standards
Creators: name: Alreshaid, Nasser
Publisher: name: American University
Year: 2023

description: Financing resources are necessarily finite. State governments may envision prospects that entail the most developed infrastructure which provides residents of the country with paramount welfare. The Gulf Cooperation Council (GCC) States of which this study is premised are undergoing a pivotal period where oil rents have experienced volatile phases and the same government means of financing promising large infrastructure projects are no longer sustainable. The study focuses on Kuwait, Saudi Arabia, and the UAE of the GCC States. The introduction of the private sector as a major actor in these countries’ development plans is a shared accord amongst the three states. This study looks into the utilization of public-private partnerships (PPPs) as a tool for the Arab Gulf governments to implement their anticipated projects by empowering the private sector. By using law and development theoretical frameworks on regulations and institutions, the study asserts that the structure of the economic systems of the GCC States as largely welfare states must be well comprehended and outlined in terms of what empowering the private sector through PPPs involves. There are key aspects in light of international investment standards that would shape Gulf States’ institutional practices when adopting PPPs. These standards may nevertheless be balanced with notions like public interest to mitigate the extreme transformation to private sector lead in state development schemes.

State governments may envision prospects that entail the most developed infrastructure which provides residents of the country with paramount welfare. The Gulf Cooperation Council (GCC) States of which this study is premised are undergoing a pivotal period where oil rents have experienced volatile phases and the same government means of financing promising large infrastructure projects are no longer sustainable. The study focuses on Kuwait, Saudi Arabia, and the UAE of the GCC States. The introduction of the private sector as a major actor in these countries’ development plans is a shared accord amongst the three states. This study looks into the utilization of public-private partnerships (PPPs) as a tool for the Arab Gulf governments to implement their anticipated projects by empowering the private sector. By using law and development theoretical frameworks on regulations and institutions, the study asserts that the structure of the economic systems of the GCC States as largely welfare states must be well comprehended and outlined in terms of what empowering the private sector through PPPs involves. There are key aspects in light of international investment standards that would shape Gulf States’ institutional practices when adopting PPPs. These standards may nevertheless be balanced with notions like public interest to mitigate the extreme transformation to private sector lead in state development schemes.

description: We calculate the absorption probability of photons radiated from the surface of the Sun by a left-handed neutrino with definite mass and a typical momentum for which we choose |p_1|=0.2 MeV, producing a heavier right-handed antineutrino. Considering two transitions the ν_1 -> ν_2 and ν_2 -> ν_3 we obtain two oscillation lengths L_{12}=4960.8 m, L_{23}=198.4 m, two absorption probabilities P_{12}^{abs.}=2.5 10^{-67}, P_{23}^{abs.}=1.2 10^{-58} and the two absorption ranges R_{12}^{abs.}=4.47 10^4 R_{\odot}=208.0 au, R_{23}^{abs.}=0.89 10^4 R_{\odot}=41.4 au, using a neutrino mass differences of \sqrt{|Δm^2_{12}|}=10 meV, \sqrt{|Δm^2_{23}|}=50 meV and associated transition dipole moments. We collect all necessary theoretical ingredients, i.e. neutrino mass and mixing scheme, induced electromagnetic transition dipole moments, quadratic charged lepton mass asymmetries and their interdependence.

description: The paper employs a dual moral hazard and adverse selection model to analyse partnerships in agribusiness under joint venture contracts with asymmetric information and imperfect quality measurement by the agent and principal both of which contribute to the final quality of the product in terms of production effort and marketing (offtake) effort, respectively. A salient feature of this paper is the analysis of the ramifications of joint venture contract for quantity and quality, which is often deficient in most previous analyses of moral hazard. The research found that contracts that have rewards based on the quantity produced weakened the agent’s incentive to make effort in ensuring quality. This finding could explain why most contracts in agriculture for products with differentiated markets rarely use retail-price conditioned contracts.

description: Flying insects are capable of vision-based navigation in cluttered environments, reliably avoiding obstacles through fast and agile maneuvers, while being very efficient in the processing of visual stimuli. Meanwhile, autonomous micro air vehicles still lag far behind their biological counterparts, displaying inferior performance at a much higher energy consumption. In light of this, we want to mimic flying insects in terms of their processing capabilities, and consequently show the efficiency of this approach in the real world. This letter does so through evolving spiking neural networks for controlling landings of micro air vehicles using optical flow divergence from a downward-looking camera. We demonstrate that the resulting neuromorphic controllers transfer robustly from a highly abstracted simulation to the real world, performing fast and safe landings while keeping network spike rate minimal. Furthermore, we provide insight into the resources required for successfully solving the problem of divergence-based landing, showing that high-resolution control can be learned with only a single spiking neuron. To the best of our knowledge, this work is the first to integrate spiking neural networks in the control loop of a real-world flying robot.

ALFRED STIEGLITZ’S EQUIVALENTS: LANDSCAPE IN THE AVIATION AGE

description: Between the years 1922 and 1935, American photographer Alfred Stieglitz (1864–1946) photographed over 300 images of clouds from his family’s property at Lake George in upstate New York. About an hour’s drive north of Albany, Lake George experienced highly changeable weather systems and, so, was a fitting site for this extensive series, known as the Equivalents. This thesis focuses on Set XX (1929), a sequence of nine photographs. Whereas a few sets include poplar trees or an indication of the ground, this set focuses almost exclusively on the sky. The clouds themselves are unnaturally angled to the un-pictured horizon and—from photograph to photograph––they shift diagonally on their vertical axis. Scholars consider the Equivalents Stieglitz’s most important late work and have read the images either symbolically or formally, but they have not considered the specific understanding of clouds in the early twentieth-century America. Reading Set XX in relation to developments in meteorology and aviation in the 1920s, this thesis argues that the photographs represent the experience of flight. Throughout his career, Stieglitz worked to champion photography as art, and ironically, drawing upon science enabled him to rival the aesthetic of landscape painting. Whereas nineteenth-century landscape paintings prioritized the horizon line and pictured their subject from a terrestrial perspective, Stieglitz used aeronautic thinking to picture humanity’s ascension into the sky. By invoking and reimagining the genre of landscape, Stieglitz posited photography as equivalent or perhaps even superior to painting.

description: 3D scanning is a complex multistage process that generates a point cloud of an object typically containing damaged parts due to occlusions, reflections, shadows, scanner motion, specific properties of the object surface, imperfect reconstruction algorithms, etc. Point cloud completion is specifically designed to fill in the missing parts of the object and obtain its high-quality 3D representation. The existing completion approaches perform well on the academic datasets with a predefined set of object classes and very specific types of defects; however, their performance drops significantly in the real-world settings and degrades even further on previously unseen object classes. We propose a novel framework that performs well on symmetric objects, which are ubiquitous in man-made environments. Unlike learning-based approaches, the proposed framework does not require training data and is capable of completing non-critical damages occurring in customer 3D scanning process using e.g. Kinect, time-of-flight, or structured light scanners. With thorough experiments, we demonstrate that the proposed framework achieves state-of-the-art efficiency in point cloud completion of real-world customer scans. We benchmark the framework performance on two types of datasets: properly augmented existing academic dataset and the actual 3D scans of various objects.

description: We extend a field theoretic approach for the investigation of the electronic charge-current density response of crystalline systems to arbitrary applied electromagnetic fields. The approach leads to the introduction of microscopic polarization and magnetization fields, as well as free charge and current densities, the dynamics of which are described by a lattice gauge theory. The spatial averages of such quantities constitute the fields of macroscopic electrodynamics. We implement this formalism to study the orbital electronic response of a class of insulators to applied uniform dc electric and magnetic fields at zero temperature. To first-order in the applied fields, the free charge and current densities vanish; thus the response of the system is characterized by the first-order modifications to the microscopic polarization and magnetization fields. Associated with the dipole moment of the microscopic polarization (magnetization) field is a macroscopic polarization (magnetization), for which we extract various response tensors. We focus on the orbital magnetoelectric polarizability (OMP) tensor, and find the accepted expression as derived from the "modern theory of polarization and magnetization." Since our results are based on the spatial averages of microscopic fields, we can identify the distinct contributions to the OMP tensor from the perspective of this microscopic theory, and we establish the general framework in which extensions to finite frequency can be made.
