description: Padmasana architecture is part of traditional Balinese architecture, it is a sacred building that functions as God's sthana (place/position). The existence of symbols as religious expressions is very thick coloring the realization of padmasana architecture, a very diverse typology, and there are still many meanings that need to be expressed. Padmasana tiga is one of the most important types of padmasana buildings, manifested from three Padmasana, standing tall on a rectangular base. Its unique shape, different from other padmasana buildings, gives rise to diverse interpretations, thereby increasing the attractiveness of this building for research. Padmasana tiga is located in the main and largest temple in Bali, Besakih Temple, on the slopes of Mount Agung, Karangasem Regency, Bali Province. The purpose of this study is to reveal the padmasana tiga functions and their typology which are closely related to the teachings of Shiva Siddhanta, so that they can be better understood by the Hindu community in Bali and the wider community. In order to express its function and typology, a descriptive qualitative method was used, by observing, documenting and interviewing Hindu priests, intellectuals who understood the Shiva Siddhanta concept, and undagi (traditional Balinese craftsman). Padmasana tiga is the embodiment of the great soul of the universe, a vertical representation of God, a God in three different realms called 'Tri Purusa'. Judging from its layout which is in the middle of the mandala (zone) facing the entrance and at its peak there are 3 rongs (empty throne), this padmasana belongs to the type of padmasana kurung (brackets). Judging from the number of rongs and the number of palih (level), which amounted to 7, padmasana tiga including the type of padmasana anglayang.

description: This paper examines the extent and source of inequality in the distribution of land holdings in Himachal Pradesh using various inequality measures. The results revealed that the trend in inequality has consistently declined, suggesting an improvement in the overall inequality in the land distribution. The Gini's Coefficient has declined from 0.6081 in 1970-71 to 0.5483 for 1985-86. Theil's indices computed separately for the number of holdings and area operated for the four time periods suggest that though the concentration is greater in the case of number of holdings than in the case of area operated yet the concentration has increased in the former and declined in the latter case.' Atkinson's index which has declined from 0.5455 in 1970-71 to 0.4110 in 1985-86 implies that same level of social welfare can be obtained with 45 per cent of the total operated land during 1970-71 and 58.9 per cent of total operated land in 1985-86. The reduction in skewness may have a favourable effect on both production and social environment.

description: In the last ten years silicon photomultipliers (SiPMs) have gained terrain in experiments and applications in which photomultiplier tubes have been the dominant photosensors during decades. Imaging Atmospheric Cherenkov Telescopes (IACTs) for very high energy (VHE, E$>$50 GeV) gamma-ray astronomy are experiencing the same process. Until now FACT was the only IACT using SiPMs. In the Cherenkov Telescope Array (CTA), the next-generation VHE gamma-ray observatory, at least 70 telescopes equipped with SiPMs are planned to be built. The first prototypes have already been constructed and are now being commissioned. Here we discuss some of the advantages and drawbacks of using SiPMs in VHE gamma-ray astronomy and provide a brief overview of different developments related to the use of SiPMs in IACTs.

description: We investigate Lie symmetries of general Yang-Mills equations. For this purpose, we first write down the second prolongation of the symmetry generating vector fields, and compute its action on the Yang-Mills equations. Determining equations are then obtained, and solved completely. Provided that Yang-Mills equations are locally solvable, this allows for a complete classification of their Lie symmetries. Symmetries of Yang-Mills equations in the Lorentz gauge are also investigated.

description: This study introduces a new "Non-Dimensional" star identification algorithm to reliably identify the stars observed by a wide field-of-view star tracker when the focal length and optical axis offset values are known with poor accuracy. This algorithm is particularly suited to complement nominal lost-in-space algorithms, which may identify stars incorrectly when the focal length and/or optical axis offset deviate from their nominal operational ranges. These deviations may be caused, for example, by launch vibrations or thermal variations in orbit. The algorithm performance is compared in terms of accuracy, speed, and robustness to the Pyramid algorithm. These comparisons highlight the clear advantages that a combined approach of these methodologies provides.

description: Diffusion may obliterate fluctuation signals of the QCD phase transition in nuclear collisions at SPS and RHIC energies. We propose a hyperbolic diffusion equation to study the dissipation of net charge fluctuations. This equation is needed in a relativistic context, because the classic parabolic diffusion equation violates causality. We find that causality substantially limits the extent to which diffusion can dissipate these fluctuations.

title: Passive and Acquired Immunity to Respiratory Syncytial Virus in Young Children in Rural Kenya
Creators: name: Ochola-Opiyo, Beldinah R.
Publisher: name: The Open University
Year: 2008

description: The rate of decay and the subsequent antibody responses to RSV are poorly defined in young infants and children who possess maternally derived respiratory syncytial virus (RSV) antibodies. A birth cohort from rural Kenya was studied intensively to monitor infections from whom blood samples were collected at regular intervals to describe the age-related serological characteristics. A simple linear regression model was used to calculate the rate of RSV-specific maternal antibody decline. In addition, the effect of risk factors on cord blood titres was investigated. Using the random effects model, the half-life of RSV maternal antibodies was calculated to be 79 days. Although 97% of infants were bom with RSV-specific maternal antibodies, it was noted that infants who went on to experience an infection in early life, had lower starting titres of RSV maternal antibodies in comparison to infants who did not have any clinically confirmed infection in the first 6 months. Additionally, clinically confirmed infections within the first 6 months of life had no effect on the rate of decay of maternal antibodies. Both RSV group A and B were seen to circulate in the community in varying amounts, with RSV A seen to be the most dominant strain in the 4 epidemics experienced by the cohort. The same RSV strain was observed to cause both RSV-associated upper respiratory tract and lower respiratory tract infections. It was observed that there existed patterns of antibody decay and acquisition of RSV-specific immune responses that groups of children appeared to follow. A group of infants were seen to undergo clinical infection that was subsequently confirmed by the ELISA, or were observed to seroconvert in the absence of clinical symptoms, or infants did not experience any infection at all despite experiencing at least 2 epidemics. Post-infection dynamics showed classical boosting of RSV antibodies, which either quickly waned or remained elevated over time. Furthermore, the risk of re-infection with clinically identified RSV illness decreased with age, from an initial infection rate of 252 to 41/1000 child years observation. In conclusion, the evidence shows that RSV maternal antibodies provide some protection against severe disease during the first 6-7 months. Since there is efficient transfer of antibodies from mother to child, maternal vaccination against RSV may be a useful strategy to consider. However, our observations show that these antibodies decline quickly, hence childhood vaccines should also be taken into consideration to augment the immune responses.

description: Elucidating the phase diagram of lattice gauge theories with fermionic matter in 2+1 dimensions has become a problem of considerable interest in recent years, motivated by physical problems ranging from chiral symmetry breaking in high-energy physics to fractionalized phases of strongly correlated materials in condensed matter physics. For a sufficiently large number $N_f$ of flavors of four-component Dirac fermions, recent sign-problem-free quantum Monte Carlo studies of lattice quantum electrodynamics (QED$_3$) on the square lattice have found evidence for a continuous quantum phase transition between a power-law correlated conformal QED$_3$ phase and a confining valence-bond-solid phase with spontaneously broken point-group symmetries. The critical continuum theory of this transition was shown to be the $O(2)$ QED$_3$-Gross-Neveu model, equivalent to the gauged Nambu-Jona-Lasinio model, and critical exponents were computed to first order in the large-$N_f$ expansion and the $ε$ expansion. We extend these studies by computing critical exponents to second order in the large-$N_f$ expansion and to four-loop order in the $ε$ expansion below four spacetime dimensions. In the latter context, we also explicitly demonstrate that the discrete $\mathbb{Z}_4$ symmetry of the valence-bond-solid order parameter is dynamically enlarged to a continuous $O(2)$ symmetry at criticality for all values of $N_f$.

Future Probes of the Neutron Star Equation of State Using X-ray Bursts

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Observations with NASA's Rossi X-ray Timing Explorer (RXTE) have resulted in the discovery of fast (200 - 600 Hz), coherent X-ray intensity oscillations (hereafter, "burst oscillations") during thermonuclear X-ray bursts from 12 low mass X-ray binaries (LMXBs). It is now beyond doubt that these oscillations result from spin modulation of the thermonuclear burst flux from the neutron star surface. Among the new timing phenomena revealed by RXTE the burst oscillations are perhaps the best understood, in the sense that many of their properties can be explained in the framework of this relatively simple model. Because of this, detailed modelling of burst oscillations can be an extremely powerful probe of neutron star structure, and thus the equation of state (EOS) of supra-nuclear density matter. The new discoveries have spurred much new theoretical work on thermonuclear burning and propagation on neutron stars, so that in the near future it is not unreasonable to think that detailed physical models of the time dependent flux from burning neutron stars will be available for comparison with the observed pulse profiles from a future, large collecting area X-ray timing observatory. In addition, recent high resolution burst spectroscopy with XMM/Newton suggests the presence of redshifted absorption lines from the neutron star surface during bursts. This leads to the possibility of using large area, high spectral resolution measurements of X-ray bursts as a precise probe of neutron star structure. In this work I will explore the precision with which constraints on neutron star structure, and hence the dense matter EOS, can be made with the implementation of such programs.

description: The local entropy production in a shock wave was analysed in the framework of non-equilibrium thermodynamics (NET) of surfaces. We show that the thermodynamic state variables in the shock front are equal to their equilibrium values, despite lack of global equilibrium in the dense gas. This observation was used to develop a theory for the entropy production in a shock wave using Gibbs' surface excess properties. The theoretical results were compared with a numerical evaluation of the entropy balance for the shock front and confirmed by non-equilibrium molecular dynamics (NEMD) simulations. The NET analysis shows that the dominant contribution to the entropy production is the dissipation of kinetic and compression energy. This opens the door to accurate representations of energy conversions in shock waves.

description: Although variations in elemental abundance ratios in the Milky Way Galaxy certainly exist, details remain uncertain, particularly in the inner Galaxy, where stars and H II regions in the Galactic plane are obscured optically. In this paper we revisit two previously studied, inner Galaxy H II regions: G333.6-0.2 and W43. We observed three new positions in G333.6-0.2 with the Kuiper Airborne Observatory and reobserved the central position with the Infrared Space Observatory's Long Wavelength Spectrometer in far-infrared lines of S++, N++, N+, and O++. We also added the N+ lines at 122 and 205 micron to the suite of lines measured in W43 by Simpson et al. (1995). The measured electron densities range from ~40 to over 4000 cm-3 in a single H II region, indicating that abundance analyses must consider density variations, since the critical densities of the observed lines range from 40 to 9000 cm-3. We propose a method to handle density variations and make new estimates of the S/H and N/H abundance ratios. We find that our sulfur abundance estimates for G333.6-0.2 and W43 agree with the S/H abundance ratios expected for the S/H abundance gradient previously reported by Simpson et al. The estimated N/H, S/H, and N/S ratios are the most reliable because of their small corrections for unseen ionization states (< 10%). We compute models of the two H II regions to estimate corrections for the other unseen ionization states. We discuss these predictions and conclude that only a few of the latest models adequately reproduce H II region observations, including the well-known, relatively-large observed Ne++/O++ ratios in low- and moderate-excitation H II regions.

description: Excerpts from the report: This study was undertaken to make available a summary of costs incurred in storing reserve stocks of wheat in several types and sizes of storage units, and to determine the economic effects of holding stocks at various positions in production areas. Its primary purpose was to aid in making decisions regarding the handling of reserve stocks over extended storage periods, taking into consideration the possibility that additional storage space may need to be built to care for large stocks of wheat. At the time the study began, the quantity of wheat owned by the Government in connection with the price-support program was not large enough to require extensive bin-site storage. For this reason records were not available on costs of storing wheat at bin sites. This report, therefore, provides information regarding costs, and factors which affect those costs, for wheat stored at two positions--country elevators and farms. Only costs of storing wheat in buildings of recent construction located in important wheat-producing areas were considered relevant to the purpose of the study.

description: This paper investigates the relationship between current account balance and budget balance in Vietnam using quarterly data from 1997Q1 to 2018Q1. Other explanatory variables are interest rate of government bonds and real exchange rate. The result reveals that all four variables, current account balance, budget balance, government bonds yield and real exchange rate, are co-integrated and there is one co-integrated vector relationship. Otherwises, using the Granger causality test, it is shown that, budget balance has a directional causality relationship with current account balance which means that the research supports Keynesian’s view and there are twin deficits happened in Vietnam during 1997 to 2018. In addition, there are two other directional relationships from real exchange rate to current account and current account to interest rate of government bonds. Furthermore, there are also other factors which can cause the two deficits individually.

description: As the world moves forward into an uncertain future our agro-ecosystems will come under increasing pressure, threatening our food security. In fact, climate change, dwindling water supplies, rising energy costs, the emergence of new pests and diseases, loss of arable land and population growth mean that our crop plants will need to yield more on less land, with fewer inputs under increasingly harsh conditions. For this reason, plant breeders will be forced to mine global plant genetic resources collections for variation that can be used to future-proof our crop plants. However, the genetic resources collections are large and we cannot afford to evaluate every accession in a collection as we hunt for desirable traits. The Focused Identification of Germplasm Strategy (FIGS) was developed to help unlock the variation in genebanks and make it more accessible to the plant breeding community. This paper explains how FIGS works and gives examples of how rare traits have been uncovered by using the technology.

description: Digital agriculture encompasses a value chain framework that supports smallholder farmers’ access to services, knowledge and markets. This helps to unlock the economic potential of agriculture, preserve natural resources and accelerate equitable economic growth in rural communities. Digital agriculture is already the nerve centre for modern food systems. It enables democratisation of information and distillation of big data analytics to provide timely and targeted insight for farmers, input suppliers, aggregators, processors and consumers. These insights are now delivered to the location of a decision (e.g. a farmer’s field on a smart phone) on how to optimise profitability, increase value chain efficiency and support consumer awareness on food and its impact on their nutrition, the rural economy and the environmental footprint of agriculture. Digital tools have the potential to compress value chains and reduce transaction costs, thus moving more value to the farmers’ end for improving incomes and livelihoods. Through ‘big data’ and systems biology, the nutritional quality of crops can be improved by gaining a deeper understanding of the interaction of food, nutrition and human health. Spatial Data Infrastructure combined with unique digital identification can support an ecosystem of integrated services to better serve the needs of farmers – whether it be access to inputs, credit, insurance or markets. Downscaled observed weather data are critically important to support all actors along the value chain, given that agriculture is a solar- and water- driven industry. Maintaining the trust of farmers and consumers is vitally important, so policies to manage personal identification information are essential. However, data also needs to be granular to support precision agriculture practices. An ecosystem of different tools and platforms supported by pragmatic and visionary policies and institutions will position countries to uniquely unlock the power of digital technology to accelerate agricultural development and ultimately enable us to deliver on the Sustainable Development Goals – one country at a time.

description: We describe the implementation of Boosted Decision Trees in the hls4ml library, which allows the translation of a trained model into FPGA firmware through an automated conversion process. Thanks to its fully on-chip implementation, hls4ml performs inference of Boosted Decision Tree models with extremely low latency. With a typical latency less than 100 ns, this solution is suitable for FPGA-based real-time processing, such as in the Level-1 Trigger system of a collider experiment. These developments open up prospects for physicists to deploy BDTs in FPGAs for identifying the origin of jets, better reconstructing the energies of muons, and enabling better selection of rare signal processes.
title: Transplantation of Pancreatic Islet in an Immunoisolation Device
Creators: name: Cornolti, Roberta
Publisher: name: The Open University
Year: 2009

description: Background: Type-1 diabetes is caused by autoimmune destruction of insulin-producing B-cells in the pancreas. Today, transplantation of whole pancreas or islets is the only treatment that can restore endogenous insulin production. Within the past 20 years, pancreatic islet transplantation has become a clinical reality and an option in diabetes treatment. However, large use of this therapy is limited by shortage in organ donations and use of immunosuppressive drugs. Immunoisolation potentially allows elimination of immunosuppressive drugs and use of xenogenic tissue solving the problem of a shortage in organ donation.

Aims: The present work was designed to ameliorate isolation of islets from different species and encapsulation of islets in immunoisolation devices (hollow fibres and microcapsules). Moreover, a mathematical model for immunoisolation membrane selection was developed.

Results and Conclusions: The application of the automated method allows significant increase in the number of islets obtained. These islets were then used for in vitro or in vivo studies of immunoisolation devices, tested in different protocols. Experimental results indicate that islet transplantation using alginate gel microcapsule in the peritoneal cavity successfully control glycaemia in diabetic animals. However, it is not possible to translate in human application for the implantation site. An alternative strategy was developed based on membrane device to be used in the subcutaneous space. Despite permeability properties have been proved to be adequate, the in vivo functional response of transplanted islet in hollow fibre device was only temporary, probably for development of fibrotic tissue around the device.

Future work: The use of theoretical model allows evaluation and selection of new membrane materials for islet immunoisolation. Efficacy of new devices would be determined by performing allo- or xeno- transplantations into diabetic recipients, exploring new sites of implantation that minimize surgical procedures and reduce implant failure.

description: Extreme price changes have become increasingly common in agricultural commodity futures markets. Many empirical studies have shown that agricultural commodity futures returns are not normally distributed and are heavy-tailed. However, most of the studies do not allow for stochastic dependence of extreme events over time. Statistical tools based on Extreme Value Theory can be utilized to model tail risk in agricultural markets. In this paper, we employ a Bayesian hierarchical model for serially-dependent extreme commodity futures price changes. The model assumes that the distribution of marginal price returns follows the generalized Pareto distribution (GPD), and reflects a serial dependence structure in tail distribution. The model proposed here allows both the parameters in the serial dependence function and the marginal GPD to vary over time. Thus, the model provides important information on changes in the shape of the heavy-tailed distribution. For empirical analysis, we use daily futures prices for corn. Based on our preliminary results, recent years have seen considerable increases in the probability of an extreme price decline in several commodity markets. These results have implications for risk management strategies as well as the design and effectiveness of federal insurance programs.

description: Suppose that a topological space $X$ is the union of an increasing sequence of open subsets each of which is homeomorphic to the Euclidean space $R^n$. Then $X$ itself is homeomorphic to $R^n$. This is an old theorem of Morton Brown. We observe that this theorem is an immediate consequence of other two theorems of Morton Brown concerning near homeomorphisms and cellular sets.

description: A vertex colouring of a graph is \emph{nonrepetitive on paths} if there is no path $v_1,v_2,...,v_{2t}$ such that v_i and v_{t+i} receive the same colour for all i=1,2,...,t. We determine the maximum density of a graph that admits a k-colouring that is nonrepetitive on paths. We prove that every graph has a subdivision that admits a 4-colouring that is nonrepetitive on paths. The best previous bound was 5. We also study colourings that are nonrepetitive on walks, and provide a conjecture that would imply that every graph with maximum degree $Δ$ has a $f(Δ)$-colouring that is nonrepetitive on walks. We prove that every graph with treewidth k and maximum degree $Δ$ has a $O(kΔ)$-colouring that is nonrepetitive on paths, and a $O(kΔ^3)$-colouring that is nonrepetitive on walks.

description: This presentation explores the deployment of mobile acquired data (MAD) via tablet-based apps in research for development initiatives. It assesses pros, cons and unexpected consequences in the field, for both researchers and smallholder farmers, using the ACIARfunded, University of Queensland Vanuatu Beef Project as a case study. In 2015, ACIAR sought to understand the potential benefits – intended and unintended – that mobile acquired data (apps on tablets) might deliver to its funded projects. In pursuit of this, AgImpact (an R4D company) was commissioned to design and manage a small research activity which reviewed nearly 20 ‘off the shelf’ apps, then conducted three weeks of field testing in Indonesia surveying beef producers, in partnership with the University of Udayana. The researchers concluded that the use of apps for in-field research has significant potential to improve relationships between researchers and smallholder farmers by improving two-way information exchange in near real time. Some of the key findings were: (i) survey times were reduced by approximately 53%; (ii) 93% of farmers found the use of apps informative when research results were provided to them in near real time; (iii) 73% of farmers found the overall survey experience using apps to be positive. By mid-2016, the research activity had gained momentum and evolved into the ACIAR Mobile Acquired Data (MAD) research series, now involving nine ACIAR projects adopting apps in research for the first time. An exemplar project led by the University of Queensland, ‘Increasing the productivity and market options of smallholder beef cattle farmers in Vanuatu’, designed and built apps featuring auto-calculation functions, look-up tables and case histories, to track changes in cattle production performance and cattle prices for individual animals in real time.
Molecular dynamics study of melting of a bcc metal-vanadium I: mechanical melting

description: We present molecular dynamics simulations of the homogeneous (mechanical) melting transition of a bcc metal, vanadium. We study both the nominally perfect crystal as well as one that includes point defects. According to the Born criterion, a solid cannot be expanded above a critical volume, at which a 'rigidity catastrophe' occurs. This catastrophe is caused by the vanishing of the elastic shear modulus. We found that this critical volume is independent of the route by which it is reached whether by heating the crystal, or by adding interstitials at a constant temperature which expand the lattice. Overall, these results are similar to what was found previously for an fcc metal, copper. The simulations establish a phase diagram of the mechanical melting temperature as a function of the concentration of interstitials. Our results show that the Born model of melting applies to bcc metals in both the nominally perfect state and in the case where point defects are present.

title: Structure and Dynamics of High Mobility Group Box Protein 1 (HMGB1) Complexed With Inhibitors of Its Proinflammatory Activity: A Combined Nuclear Magnetic Resonance and Computational Chemistry Approach
Creators: name: Mollica, Luca
Publisher: name: The Open University
Year: 2008

description: High-mobility group box 1 protein (HMGB1) is a nuclear component, but extracellularly it serves as a signaling molecule involved in acute and chronic inflammation, for example in sepsis and arthritis. The identification of HMGB1 inhibitors is therefore of significant experimental and clinical interest. We show that glycyrrhizin, a natural antiinflammatory and antiviral triterpene in clinical use, inhibits HMGB1 chemoattractant and mitogenic activities, and has a weak inhibitory effect on its intranuclear DNA binding function. NMR and fluorescence studies indicate that glycyrrhizin (and its analogue carbenoxolone) binds directly to HMGB1 (Kd ~ 150 μM), interacting with two shallow concave surfaces formed by the two arms of both HMG boxes, altering the internal mobility of proteins (on the millisecond timescale for Box A, on the nanosecond timescale for Box B) without significantly altering their overall diffusive properties. Due to the reduced number of experimentally determined intermolecular contacts, by means of two different computational approaches (QRFF for the Box A - carbenoxolone complex, HADDOCK data driven docking for the glycyrrhizin containing complexes) it was possible to obtain an atomic level model of the protein-ligand interactions. The presented results explain in part the anti-inflammatory properties of glycyrrhizin, and might direct the design of new derivatives with improved HMGB1-binding properties.

Deuteron polarizations in the proton-deuteron Drell-Yan process for finding the gluon transversity

description: The gluon transversity distribution in the deuteron is defined by the matrix element between linearly-polarized deuteron states, and it could be investigated in proton-deuteron collisions in addition to lepton-deuteron scattering. The linear polarization of photon is often used, whereas it is rarely used for the spin-1 deuteron. Therefore, it is desirable to express deuteron-reaction cross sections in term of conventional deuteron spin polarizations for actual experimental measurements. In this work, we investigate how proton-deuteron Drell-Yan cross sections are expressed by the conventional polarizations for finding the gluon transversity distribution. In particular, we show that the gluon transversity can be measured in the proton-deuteron Drell-Yan process by taking the cross-section difference between the deuteron spin polarizations along the two-transverse axes. Since the gluon transversity does not exist for the spin-1/2 nucleons, a finite gluon transversity of the deuteron could indicate an "exotic" mechanism beyond the simple bound system of the nucleons in the deuteron. Therefore, the gluon transversity is an interesting and appropriate observable to shed light on a new hadronic mechanism in nuclei.

description: This paper is concerned with longtime dynamics of semilinear Lamé systems $$ \partial^2_t u - μΔu - (λ+ μ) \nabla {\rm div} u + α\partial_t u + f(u) = 0, $$ defined in bounded domains of $\mathbb{R}^3$ with Dirichlet boundary condition. Firstly, we establish the existence of finite dimensional global attractors subjected to critical forcings $f(u)$. Writing $λ+ μ$ as a positive parameter $\varepsilon$, we discuss some physical aspects of the limit case $\varepsilon \to 0$. Then, we show the upper-semicontinuity of attractors with respect to the parameter when $\varepsilon \to 0$. To our best knowledge, the analysis of attractors for dynamics of Lamé systems has not been studied before.
