description: We consider the class of higher derivative field equations whose wave operator is a square of another self-adjoint operator of lower order. At the free level, the models of this class are shown to admit a two-parameter series of integrals of motion. The series includes the canonical energy. Every conserved quantity is unbounded in this series. The interactions are included into the equations of motion such that a selected representative in conserved quantity series is preserved at the non-linear level. The interactions are not necessarily Lagrangian, but they admit Hamiltonian form of dynamics. The theory is stable if the integral of motion is bounded from below due to the interaction. The motions are finite in the vicinity of the conserved quantity minimum. The equations of motion for fluctuations have the derived form with no resonance. The general constructions are exemplified by the models of the Pais-Uhlenbeck oscillator with multiple frequency and Podolsky electrodynamics. The example is also considered of stable non-abelian Yang-Mills theory with higher derivatives.

description: We report on the detection of low-column density neutral hydrogen clumps in the halo of the Milky Way. Using high-resolution (FWHM~7 km/s) optical spectra obtained with the VLT/UVES spectrograph we detect narrow interstellar absorption by CaII and NaI at high radial velocities near -150 km/s toward the quasar PKS 1448-232 (l=335.4, b=+31.7). Follow-up HI 21cm observations with the VLA unveil the presence of a complex of small neutral hydrogen clumps with HI column densities <8x10^18 cm^-2. The measured HI line widths imply that the gas is relatively cold with temperatures T<900 K. Although the line of sight towards PKS 1448-232 does not pass immediately through a known large high-velocity cloud (HVC), the sky position and the measured radial velocities suggest that these clumps are associated with HVC cloud complex L. An inspection of other UVES quasar spectra shows that weak, narrow CaII absorption at high velocities is a common phenomenon, even in directions where high-velocity HI 21cm emission is not detected. This suggests that the Milky Way halo contains a large number of high-velocity neutral gas clumps with low HI column densities. If such clumps are typical for halos of spiral galaxies, they should contribute significantly to the population of strong MgII absorbers and Lyman-Limit Systems (LLS) seen in the circumgalactic environment of other galaxies.

description: Adenosine receptors are G-protein-coupled receptors involved in a wide range of physiological and pathological phenomena in most mammalian systems. All four receptors are widely expressed in the central nervous system, where they modulate neurotransmitter release and neuronal plasticity. A large number of gene association studies have shown that common genetic variants of the adenosine receptors (encoded by the ADORA1, ADORA2A, ADORA2B and ADORA3 genes) have a neuroprotective or neurodegenerative role in neurologic/psychiatric diseases. New genetic studies of rare variants and few novel associations with depression or epilepsy subtypes have recently been reported. Here, we review the literature on the genetics of adenosine receptors in neurologic and/or psychiatric diseases in humans, and discuss perspectives for further genetic research. We also provide an update on the genetic structures of the four human adenosine receptor genes and their regulation - a topic that has not been extensively addressed. Our review emphasizes the importance of (i) better characterizing the genetics of adenosine receptor genes and (ii) understanding how these genes are regulated.

Hodge Duality and Cosmological Constant

Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We present a simple mechanism to eliminate cosmological constants both in supersymmetric and non-supersymmetric theories. This mechanism is based on the Hodge (Poincare) duality between a 0-form and D-form field strengths in D-dimensional space-time. The new key ingredient is the introduction of an extra Chern-Simons term into the D-form field strength H dual to the 0-form field strength. Our formulation can be also made consistent with supersymmetry. Typical applications to four-dimensional N=1 supergravity and to ten-dimensional type IIA supergravity are given. The success of our formulation for both supersymmetric and non-supersymmetric systems strongly indicates the validity of our mechanism even after supersymmetry breakings at the classical level. Our mechanism may well be applicable to quantized systems, at least for supersymmetric cases with fundamental D-brane actions available.

description: We obtain the asymptotic density of open p-brane states with zero-modes included. The resulting logarithmic correction to the p-brane entropy has a coefficient - \frac{p + 2}{2 p}, and is independent of the dimension of the embedding spacetime. Such logarithmic corrections to the entropy, with precisely this coefficient, appear in two other contexts also: a gas of massless particles in p-dimensional space, and a Schwarzschild black hole in (p + 2)-dimensional anti de Sitter spacetime.

title: The Work of Lionel Britton
Creators: name: Shaw, Tony
Publisher: name: The Open University
Year: 2007

description: This thesis is the first long study of the forgotten novelist and playwright Lionel Britton, whose creative works were all published in the 1930s. Throughout, the emphasis is on his only published novel, the very long and experimental Hunger and Love (1931). The Lionel Britton Collection at Southern Illinois University in Carbondale, U. S. A., along with many unpublished materials of Britton's, holds former states of the novel, and I use a large amount of this material in my thesis; I suggest reasons why the content of the typescripts was gradually changed from the 1920s to 1930. Another vital issue is Britton's status as a working-class author, and it is my contention that Hunger and Love is an important working-class novel, although it has been almost totally neglected by the critics recovering this sub-genre. My thesis also addresses modernism in working-class fiction, a subject which has all too often been ignored by the almost automatic foregrounding of realism, and is a strong feature of Hunger and Love. Following this, my thesis broadens out to cover political minorities represented as outsiders in literature, and deals with the unmarried woman, the homosexual and the non-white, comparing them with the working-class protagonist in Hunger and Love. The concluding chapter involves the utopias and dystopias of minority groups, with special reference to Britton's Brain (1930) and Spacetime Inn (1932), which as plays are very unusual to the science fiction genre.

description: In minimal invasive surgery, it is important to rebuild and visualize the latest deformed shape of soft-tissue surfaces to mitigate tissue damages. This paper proposes an innovative Simultaneous Localization and Mapping (SLAM) algorithm for deformable dense reconstruction of surfaces using a sequence of images from a stereoscope. We introduce a warping field based on the Embedded Deformation (ED) nodes with 3D shapes recovered from consecutive pairs of stereo images. The warping field is estimated by deforming the last updated model to the current live model. Our SLAM system can: (1) Incrementally build a live model by progressively fusing new observations with vivid accurate texture. (2) Estimate the deformed shape of unobserved region with the principle As-Rigid-As-Possible. (3) Show the consecutive shape of models. (4) Estimate the current relative pose between the soft-tissue and the scope. In-vivo experiments with publicly available datasets demonstrate that the 3D models can be incrementally built for different soft-tissues with different deformations from sequences of stereo images obtained by laparoscopes. Results show the potential clinical application of our SLAM system for providing surgeon useful shape and texture information in minimal invasive surgery.

description: 1E 1740.7-2942 is one of the strongest hard X-ray emitters in the Galactic Centre region, believed to be a black hole in a high-mass X-ray binary system. Although extensively studied in X-rays, many aspects about the underlying nature of the system are still unknown. For example, X-ray data analyses of 1E 1740.7-2942 up to date have not yet unveiled the signature of a reflection component, whose modelling could be used to estimate parameters such as the spin of the black hole and inclination of the disc. We report here on the determination of these parameters from the analysis of the reflection component present in a public \textit{NuSTAR} observation which hasn't been subject to any previous study. We include \textit{XMM-Newton} and \textit{INTEGRAL} data to build a combined spectrum, enabling a joint analysis of both the disc and comptonisation components. Results point to a relatively high inclination disc $\gtrsim$ 50$^{\circ}$ (3 $σ$) and a near-maximum speed rotating black hole. The former is in agreement with a previous radio study and the latter is reported here for the first time. Lastly, we follow the methodology of recent efforts to weight black holes with only X-ray spectra and find results that suggest a black hole mass of about 5 M$_\odot$ for 1E 1740.7-2942.

description: Context
Lack of education, stigma, and negative self-attitudes are key barriers to help-seeking in Gaelic footballers. With the prevalence of mental health issues in Gaelic footballers and the increased risk of experiencing mental health challenges after injury, mental health literacy (MHL) interventions are necessary.
Objectives
To design and implement a novel MHL educational intervention program in Gaelic footballers.
Design
Controlled laboratory study.
Setting
Online.
Patients or Other Participants
Elite and subelite Gaelic footballers divided into intervention (n = 70; age = 25.1 ± 4.5 years) and control (n = 75; age = 24.4 ± 6.0 years) groups. In the intervention group, 85 participants were recruited, but 15 dropped out after completing baseline measures.
Interventions
A novel educational intervention program, “GAA [Gaelic Athletic Association] and Mental Health—Injury and a Healthy Mind,” was designed to address the key components of MHL and was underpinned by the Theory of Planned Behavior and the Help-Seeking Model. The intervention was implemented online via a brief 25-minute presentation.
Main Outcome Measures
Measures of stigma, help-seeking attitudes, and MHL were completed by the intervention group at baseline, immediately after viewing the MHL program, and at 1 week and 1 month after the intervention. The control group completed the measures at similar time points.
Results
Stigma decreased, and attitudes toward help-seeking and MHL increased in the intervention group from baseline to after the intervention (P < .05), with significant differences sustained at 1-week and 1-month follow-ups. Our results showed differences in stigma, attitudes, and MHL between groups across time points. Intervention participants provided positive feedback, and the program was appraised as informative.
Conclusions
Remote online delivery of a novel MHL educational program can effectively decrease mental health stigma, improve attitudes toward help-seeking, and increase the recognition and knowledge of mental health issues. Gaelic footballers with improved MHL may be better equipped to manage their mental health and cope with stressors, leading to improved mental health outcomes and overall mental well-being.
Improving Transaction Success Rate via Smart Gateway Selection in Cryptocurrency Payment Channel Networks

description: The last decade has experienced a vast interest in Blockchain-based cryptocurrencies with a specific focus on the applications of this technology. However, slow confirmation times of transactions and unforeseeable high fees hamper their wide adoption for micro-payments. The idea of establishing payment channel networks is one of the many proposed solutions to address this scalability issue where nodes, by utilizing smart contracting, establish payment channels between each other and perform off-chain transactions. However, due to the way these channels are created, both sides have a certain one-way capacity for making transactions. Consequently, if one sides exceeds this one-way capacity, the channel becomes useless in that particular direction, which causes failures of payments and eventually creates an imbalance in the overall network. To keep the payment channel network sustainable, in this paper, we aim to increase the overall success rate of payments by effectively exploiting the fact that end-users are usually connected to the network at multiple points (i.e., gateways) any of which can be used to initiate the payment. We propose an efficient method for selection of the gateway for a user by considering the gateway's inbound and outbound payment traffic ratio. We then augment this proposed method with split payment capability to further increase success rate especially for large transactions. The evaluation of the proposed method shows that compared to greedy and maxflow-based approaches, we can achieve much higher success rates, which are further improved with split payments.

Contaminants in ATCA baselines with shadowing: a case study of cross talk in short-spacing interferometers

description: Interferometric telescopes made of close-packed antenna elements are an important tool for imaging extended radio sources, specifically structures that have angular sizes comparable to or even greater than the FWHM of the beams of the antennas. They have proved useful in observations of cosmic microwave background anisotropies that require high brightness-sensitivity. However, the visibilities measured in baselines formed between close antenna elements -- in particular, between shadowed elements -- of Fourier-synthesis arrays are often observed to be corrupted. We discuss the multiplicative and additive errors affecting such short-baseline interferometers. As a case study, we have examined the nature of the spurious correlations between the Cassegrain-type paraboloidal reflectors that are elements of the Australia Telescope Compact Array. In configurations with geometric shadowing, the cross talk here appears as an additive component. Analysis of the characteristics of this cross talk leads us to believe that when these reflector antennas are in a shadowed configuration, the receivers in the antenna pair pick up correlated emission from opposite sides of the main reflector surface of the front antenna. The slots between the panels that make up the main reflector surface provide the pathway for the coupling across the reflector surface. This mode of cross talk may be avoided by constructing the main reflectors of short spacing interferometers as continuous conducting surfaces.

Optical memories and switching dynamics of counterpropagating light states in microresonators

description: The Kerr nonlinearity can be a key enabler for many digital photonic circuits as it allows access to bistable states needed for all-optical memories and switches. A common technique is to use the Kerr shift to control the resonance frequency of a resonator and use it as a bistable, optically-tunable filter. However, this approach works only in a narrow power and frequency range or requires the use of an auxiliary laser. An alternative approach is to use the asymmetric bistability between counterpropagating light states resulting from the interplay between self- and cross-phase modulation, which allows light to enter a ring resonator in just one direction. Logical HIGH and LOW states can be represented and stored as the direction of circulation of light, and controlled by modulating the input power. Here we study the switching speed, operating laser frequency and power range, and contrast ratio of such a device. We reach a bitrate of 2 Mbps in our proof-of-principle device over an optical frequency range of 1 GHz and an operating power range covering more than one order of magnitude. We also calculate that integrated photonic circuits could exhibit bitrates of the order of Gbps, paving the way for the realization of robust and simple all-optical memories, switches, routers and logic gates that can operate at a single laser frequency with no additional electrical power.

description: Increasing rate of unemployment among the graduates of Iranian higher agricultural education system has been developed into one of the major socio-economic problems of the nation. Entrepreneurship is one of the most important factors contributing to economic and social development, that is, it is a main driver for employment creation. As such, many policy initiatives in Iran attempt to pull agricultural students toward an entrepreneurial career choice. In this regard, considering the importance of entrepreneurship, and applying Ajzen’s (1991) theory of planned behavior, the present study was conducted to investigate the factors affecting entrepreneurial behavior of agricultural students in Razi University. The population of this study consisted of all senior agricultural students of Razi University in Iran (N=300), 169 of whom were selected as the sample using the proportional stratified sampling method. Data were analyzed by SPSS and AMOS version23 software in two phases of descriptive and inferential statistics. Results of structural equation modeling revealed that personal attitude toward entrepreneurship, perceived behavioral control, and subjective norm were the main predictors of entrepreneurial intention (R 2 =0.46) and behavior (R 2 =0.45) among agricultural students. The findings of this study can have practical implications concerning the promotion of entrepreneurial intention and behavior among agricultural students for higher agricultural education managers, planners, and educators.

description: The main objective of this study was identifying the effects of educational, extension and research factors on the development of medicinal plants in Markazi Province of Iran. The statistical population included all managers, extension agents and experts involved in medicinal plants in Markazi Province in 2014 (N = 50), who were selected by the census sampling method (n=50). The research instrument was a questionnaire whose face and content validity were confirmed by a panel of experts and specialists of medicinal plants and also its reliability was estimated by Cronbach's alpha to be 0.78. Results showed that some factors such as informing and training the people about medicinal plants via television and training the physicians about medicinal plants benefits prove more effective in the development of this industry. On the other hand, from among five main factors which explained the variance of medicinal plants development factors, the following three factors have priority: training and extension of medicinal plants (Var. =16.54), educational standards of medicinal plants (Var. =13.18), and technical and vocational education (Var. =11.48). Also, the variables of education level, job experience in agriculture section, current attitude towards development of prescribing medicinal plants by physicians, current amount of using medicinal plants capacity in the province, and assessment of current attitudes toward medicinal plants production, have caused more significant difference in the view of statistical sample about the effect of some educational, extension and research factors on the medicinal plants industry development.

description: We study the phase diagram of the two-dimensional fully frustrated XY model (FFXY) and of two related models, a lattice discretization of the Landau-Ginzburg-Wilson Hamiltonian for the critical modes of the FFXY model, and a coupled Ising-XY model. We present Monte Carlo simulations on square lattices $L\times L$, $L\lesssim 10^3$. We show that the low-temperature phase of these models is controlled by the same line of Gaussian fixed points as in the standard XY model. We find that, if a model undergoes a unique transition by varying temperature, then the transition is of first order. In the opposite case we observe two very close transitions: a transition associated with the spin degrees of freedom and, as temperature increases, a transition where chiral modes become critical. If they are continuous, they belong to the Kosterlitz-Thouless and to the Ising universality class, respectively. Ising and Kosterlitz-Thouless behavior is observed only after a preasymptotic regime, which is universal to some extent. In the chiral case, the approach is nonmonotonic for most observables, and there is a wide region in which finite-size scaling is controlled by an effective exponent $ν_{\rm eff} \approx 0.8$. This explains the result $ν\approx 0.8$ of many previous studies using smaller lattices.

description: This research presents a coordination approach for the expansion of gas transportation networks to serve an increasing customer base. An empirical study of natural gas markets in the southeastern United States shows that horizontal cooperation among transportation service providers (i.e., pipeline companies) allows for expanding the gas transportation networks efficiently to serve new customers. The benefits of coordination are identified through key structural elements such as number and location of additional pipeline links, lower infrastructure expansion costs, and demand segmentation for the gas transportation service providers.

description: We present predictions for the double parton scattering (DPS) four-jet production cross sections in $pA$ collisions at the LHC. Relying on the experimental capabilities to correlate centrality with impact parameter $B$ of the proton-nucleus collision, we discuss a strategy to extract the double parton scattering contributions in $pA$ collisions, which gives direct access to double parton distribution in the nucleon. We show that the production cross sections via DPS of four jets, out of which two may be light- or heavy-quark jets, are large enough to allow the method to be used already with data accumulated in 2016 $pA$ run.

description: Strategic environmental sustainability management is and can be practiced in a wide variety of economic sectors worldwide, but many such sectors have yet to be recognized for doing so. This paper identifies three global economic sectors --- the direct selling, sports, and military sectors --- as exhibiting “environmentally-hidden” profiles, and discusses reasons why that situation exists, why it deserves attention, and how it can be addressed. In addition, the paper forwards several suggestions that emanate from that analysis on how strategic environmental sustainability management can be upgraded to produce better environmentally sustainable results. Finally, implications are advanced for researchers to explore and for practitioners to encourage other “environmentally- hidden” economic sectors to upgrade their environmental profiles for more significant and urgently necessary societal greening.

description: Accurate prediction of bridge component condition over time is critical for determining a reliable maintenance, repair, and rehabilitation (MRR) strategy for highway bridges. Based on bridge inspection data, regression models are the most-widely adopted tools used by researchers and state agencies to predict future bridge condition (FHWA 2007). Various regression models can produce quite different results because of the differences in modeling assumptions. The evaluation of model quality can be challenging and sometimes subjective. In this study, an external validation procedure was developed to quantitatively compare the forecasting power of different regression models for highway bridge component deterioration. Several regression models for highway bridge component rating over time were compared using the proposed procedure and a traditional apparent model evaluation method based on the goodness-of-fit to data. The results obtained by applying the two methods are compared and discussed in this paper.
Towards a Stringy Resolution of the Cosmological Singularity

description: We study cosmological solutions to the low-energy effective action of heterotic string theory including possible leading order $α'$ corrections and a potential for the dilaton. We consider the possibility that including such stringy corrections can resolve the initial cosmological singularity. Since the exact form of these corrections is not known the higher-derivative terms are constructed so that they vanish when the metric is de Sitter spacetime. The constructed terms are compatible with known restrictions from scattering amplitude and string worldsheet beta-function calculations. Analytic and numerical techniques are used to construct a singularity-free cosmological solution. At late times and low-curvatures the metric is asymptotically Minkowski and the dilaton is frozen. In the high-curvature regime the universe enters a de Sitter phase.

description: Musical gestures connect the symbolic layer of the score to the physical layer of sound. I focus here on the mathematical theory of musical gestures, and I propose its generalization to include braids and knots. In this way, it is possible to extend the formalism to cover more case studies, especially regarding conducting gestures. Moreover, recent developments involving comparisons and similarities between gestures of orchestral musicians can be contextualized in the frame of braided monoidal categories. Because knots and braids can be applied to both music and biology (they apply to knotted proteins, for example), I end the article with a new musical rendition of DNA.

description: We calculate differential cross sections for proton-nucleus elastic scattering by using a Glauber theory in the optical limit approximation and nucleon distributions that can be obtained in the framework of macroscopic nuclear models in a way dependent on the equation of state of uniform nuclear matter near the saturation density. We find that the peak angle calculated for unstable neutron-rich nuclei in the small momentum transfer regime increases as the parameter L characterizing the density dependence of the symmetry energy decreases. This is a feature associated with the L dependence of the predicted matter radii.

title: Effects of tumour hypoxia on cell migration
Creators: name: Schioppa, Tiziana
Publisher: name: The Open University
Year: 2006

description: Cell adaptation to hypoxia requires activation of transcriptional programs that coordinate expression of genes involved in oxygen delivery (via angiogenesis) and metabolic adaptation (via glycolisis). During migration and invasion of normal and pathological tissues, cells may encounter different oxygen levels, due to poor or altered vascularization, and recent evidence has suggested that chemotaxis is a cell function which may be affected by oxygen availability.

This thesis describes how oxygen avaibility is a determinant parameter in the setting of chemotactic responsiveness to Stromal-Derived Factor 1 (SDF-1, CXCL12). Low oxygen concentration induces high expression of the CXCL12 receptor CXCR4, in different cell types (monocytes, monocyte-derived macrophages, tumor associated macrophages, endothelial cells, cancer cells and dendritic cells) as both mRNA and protein expression, which is paralleled by increased chemotactic responsiveness to its specific ligand. Furthermore, preliminary results on dendritic cells (DC) show that hypoxia may affect their maturation (CCR7low/CCR5high) and functions. In particular, hypoxia-derived DC do not migrate in response to the CCR7 ligand CCL 19, while they do express higher levels of pro-inflammatory cytokines (IL-12, TNF-α), as compared to normoxia-derived DC. CXCR4 induction by hypoxia is dependent on both activation of hypoxia-inducible factor 1 (HIF-1α) and transcript stabilization. Our data identify the hypoxia/HIF-1/CXCR4 pathway as a relevant molecular circuit in the functional tuning of the chemokine system and provide novel insights into the mechanisms controlling cell migration in hypoxic regions, with potential relevance in the pathogenesis of human diseases, including chronic inflammatory diseases and cancer.

description: This paper analyzes the influence of driving knowledge on highway safety by estimating regression models on U.S. state-level data over six years (2005 through 2010). The models incorporate a representative set of motor vehicle fatality determinants. Driving knowledge?as measured by performance on the GMAC Insurance National Drivers Test?has a statistically significant lifesaving effect. Negatively related to the motor vehicle death rate and statistically significant are: real per capita income, precipitation, seat belt use, and a linear trend. Statistically significant positive associations with the rate are found for: the ratio of rural to urban driving, temperature, the percentage of young drivers, the percentage of old drivers, and alcohol consumption.

description: According to the topological design theory and method of parallel mechanism (PM) based on position and orientation characteristic (POC) equations, this paper studied a 3-DOF translational PM that has three advantages, i.e., (i) it consists of three fixed actuated prismatic joints, (ii) the PM has analytic solutions to the direct and inverse kinematic problems, and (iii) the PM is of partial motion decoupling property. Firstly, the main topological characteristics, such as the POC, degree of freedom and coupling degree were calculated for kinematic modeling. Thanks to these properties, the direct and inverse kinematic problems can be readily solved. Further, the conditions of the singular configurations of the PM were analyzed which corresponds to its partial motion decoupling property.

description: It is shown that the definition for the volume of stationary black holes advocated in hep-th/0508108 readily generalizes to the case of dilaton gravity in D=2. The dilaton field is included as part of the measure. A feature observed in D=3 and 4 has been the impossibility to obtain infinite volume while retaining finite area without encountering some kind of pathology. It is demonstrated that this also holds in D=2. Consistency with spherically reduced gravity is shown. For the Witten black hole it is found that the area is proportional to the volume.
