description: Land Use and Land Cover (LULC) changes significantly impact groundwater resources, particularly in regions experiencing rapid urbanization and agricultural expansion. In Anambra State, Southeastern Nigeria, these dynamics are crucial for understanding groundwater availability and sustainability. This study aims to analyze the temporal changes in LULC between 2017 and 2023 in Anambra State and assess their implications on groundwater recharge and dynamics. The study utilizes remote sensing data and Geographic Information Systems (GIS) to map and analyze LULC changes over seven years. The LULC categories include Trees, Rangeland, Built Area, Crops, Water bodies, Flooded Vegetation, and Bare Ground. The data are statistically analyzed to determine trends and variations in land cover types. The results indicate a significant reduction in tree cover from 1,807.49 km² in 2017 to 1,345.35 km² in 2023, accompanied by an increase in built-up areas from 1,105.26 km² to 1,329.77 km². Cropland expanded considerably from 235.03 km² in 2020 to 437.04 km² in 2023. Rangeland coverage fluctuated, peaking at 1,700.13 km² in 2022 before decreasing to 1,345.51 km² in 2023. Water bodies remained relatively stable, while Flooded Vegetation saw a significant decline from 160.13 km² in 2019 to 22.07 km² in 2023. The reduction in tree cover and the expansion of built-up areas are likely to decrease groundwater recharge due to reduced infiltration and increased surface runoff. The expansion of croplands suggests increased groundwater extraction for irrigation, potentially leading to over-extraction and depletion of groundwater reserves. The variability in rangeland and flooded vegetation areas reflects changes in land management practices, which also influence groundwater dynamics. The study highlights the critical need for sustainable land management practices to protect groundwater resources in Anambra State. The observed LULC changes pose a significant threat to groundwater recharge, emphasizing the need for policies that balance development with groundwater conservation. This study provides a comprehensive temporal analysis of LULC changes over seven years and their direct implications on groundwater dynamics in a rapidly urbanizing region.

description: Following the suggestion of hep-th/0506249 and hep-th/0612011, we represent quarter BPS dyons in N=4 supersymmetric string theories as string network configuration and explore the role of genus two surfaces in determining the spectrum of such dyons. Our analysis leads to the correct contour prescription for integrating the partition function to determine the spectrum in different domains of the moduli space separated by the walls of marginal stability.

description: Understanding how the brain segregates and binds complex information distributed in time is a challenging endeavour for the neuroscientific community, requiring computationally and neurobiologically informed approaches to solve. Language is a salient example of the complexity of the binding problem, where hierarchically organized dependencies (for example, nested dependencies between words and phrases in sentences) feature prominently. However, the problem is not unique to language nor humans, since binding in the time domain is relevant for auditory cognition more generally and for executing complex action sequences. To understand the contributions of the diverse regions involved in this process, it is increasingly important that we generate specific, testable, and mutually consistent hypotheses. Vector symbolic architectures are ideally placed to serve as a common language for neurocomputational hypothesis generation and triangulation of evidence across domains. Here we provide evidence for a vector symbolic account of the mechanisms supporting sequence representation in the human brain.

description: The Casimir And Non-Newtonian force EXperiment (CANNEX) implements the unique geometry of macroscopic plane parallel plates that guarantees an optimum sensitivity with respect to interfacial forces and their gradients. Based on experience from the recently completed proof-of-principle phase, we have started a re-design of the setup aiming to reduce systematic effects and maximize the achievable sensitivity. Several propositions have been made to measure Casimir forces in and out of thermal equilibrium, hypothetical axion and axion-like dark matter interactions, and forces originating from chameleon or symmetron dark energy interactions. In the present article, we give details on the design for the next implementation stage of CANNEX and discuss the experimental opportunities as well as limitations expected for this new setup.
Streamflow generation in a sub-alpine basin in the coast mountains of British Columbia
Creators: name: Barrett, Gary Edward
Publisher: name: University of British Columbia
Year: 2010

description: Stormflow generation was studied in a two square kilometre, sub-alpine, first-order basin tributary to Ryan River, which is in the Pacific Ranges of the Coast Mountains of British Columbia. Preliminary field work suggested that neither saturation overland flow nor subsurface stormflow were important mechanisms of stormflow generation Hortonian overland flow appeared to be dominant. The infiltrability of the soils dropped considerably during storm events. Three possible causes of this decline were considered initially: (1) a reduction in capillary gradients as wetting proceeds, (2) a textural contrast in the profile, and (3) air entrapment. All of the preceeding were rejected on the basis of more detailed observations. Instead, it was proposed that a water-repellent layer existed near the top of the soil profile. Laboratory experiments conducted on intact soil samples demonstrated that a repellent layer on the order of a few centimetres thickness did exist near the soil surface. The implications of this finding for infiltration and stormflow generation are discussed.

description: We investigate fully nonlinear, non-Abelian excitations of quark-antiquark plasma, using relativistic fluid theory in cold plasma approximation. There are mainly three important nonlinearities, coming from various sources such as non-Abelian interactions of Yang-Mills (YM) fields, Wong's color dynamics and plasma nonlinearity, in our model. By neglecting nonlinearities due to plasma and color dynamics we get back the earlier results of Blaizot {\it et. al.}, Phys. Rev. Lett. 72, 3317 (1994). Similarly, by neglecting YM fields nonlinearity and plasma nonlinearity, it reduces to the model of Gupta {\it et. al.}, Phys. Lett. B498, 223 (2005). Thus we have the most general non-Abelian mode of quark-gluon plasma (QGP). Further, our model resembles the problem of propagation of laser beam through relativistic plasma, Physica 9D, 96 (1983). in the absence of all non-Abelian interactions.

description: Recently, a theoretical study [Li {\it et al.},~npj Quantum Materials 6, 36 (2021)] investigated a model of a disordered $d$-wave superconductor, and reported local time-reversal symmetry breaking current loops for sufficiently high disorder levels. Since the pure $d$-wave superconducting state does not break time-reversal symmetry, it is surprising that such persistent currents arise purely from nonmagnetic disorder. Here we perform a detailed theoretical investigation of such disorder-induced orbital currents, and show that the occurrence of the currents can be traced to local extended $s$-wave pairing. We discuss the energetics leading to regions of $s\pm id$ order, which support spontaneous local currents in the presence of inhomogeneous density modulations.

description: Schemes to generate Greenberger-Horne-Zeilinger(GHZ) and W states of three distant atoms are proposed in this paper. The schemes use the effects of quantum statistics of indistinguishable photons emitted by the atoms inside optical cavities. The advantages of the schemes are their robustness against detection inefficiency and asynchronous emission of the photons. Moreover, in Lamb-Dicke limit, the schemes do not require simultaneous click of the detectors, this makes the schemes more realizable in experiments.

description: DC and ac magnetization, resistivity, specific heat, and neutron diffraction data reveal that stoichiometric LaOFeP is metallic and non-superconducting above T = 0.35 K, with gamma = 12.5 mJ/mol*K. Neutron diffraction data at room temperature and T = 10 K are well described by the stoichiometric, tetragonal ZrCuSiAs structure and show no signs of structural distortions or long range magnetic ordering, to an estimated detectability limit of 0.07 uB/Fe. We propose a model, based on the shape of the iron-pnictide tetrahedron, that explains the differences between LaOFeP and LaOFeAs, the parent compound of the recently discovered high-Tc oxyarsenides, which, in contrast, shows both structural and spin density wave (SDW) transitions.

Development and Evaluation of Therapeutic Mixed Reality Applications
Creators: name: Mostajeran, Fariba
Publisher: name: Zenodo
Year: 2021

description: Mixed Reality (MR) Pharmacy aims at examining psycho-physiological effects of exposure
 to and interaction with a collection of MR-based therapeutic applications. The scope of the
 research was narrowed down to personal prevention and management of specific disorders,
 which mainly fall in the category of mental disorders, i.e., Anxiety Disorders, Psychotic
 Disorders, Mood Disorders, Alcohol Use Disorders, and Cognitive Disorders. Moreover, in
 order to take into account the ageing population, a particular age-related category of disorders,
 namely Balance Disorders was included in this work as well.
 For each of these disorders, MR-based therapeutic interventions were designed, developed,
 and evaluated. Along the way, some of the clinical-MR challenges, such as validation, usability,
 and acceptance were tackled. To measure different aspects of these interventions,
 including their effects on human psychology, physiology, and cognition, several user studies
 were conducted. Additionally, the developed MR-based interventions were validated against
 in-vivo, control, or non-immersive alternative conditions. The usability of the applications
 was also measured along with the user experience and acceptance.
 The results show that MR provides enormous advantages over tested alternatives. Depending
 on the disorder and the needs of the therapy receivers, MR-based interventions can
 be used to decrease or increase psycho-physiological reactions such as anxiety. For instance,
 for treating Social Anxiety Disorders, one can increase Social Anxiety in training situations,
 whereas for treating Depressive and Mood Disorders, one can elevate mood and decrease anxiety
 levels. Moreover, we observed positive effects of exposure to virtual natural environments
 on human cognition. The MR-based applications were well accepted as well, as users found
 them novel, encouraging, and stimulating. Furthermore, obtained functional brain connectivity
 between brain regions as a result of training in MR, imply that MR may be most suited
 for long-term brain training interventions. Finally, the outcomes of this research provide
 evidence for practice and facilitate forming the foundations of planning future clinical trials.

description: Quantum Key Distribution (QKD) using polarisation encoding can be hard to implement over deployed telecom fibres because the routing geometry and the birefringence of the fibre link can alter the polarisation states of the propagating photons. These alterations cause a basis mismatch, leading to an increased Quantum Bit Error Rate (QBER). In this work we demonstrate a technique for dynamically compensating fibre-induced state alteration in a QKD system over deployed fibre. This compensation scheme includes a feedback loop that minimizes the QBER using a stochastic optimization algorithm.

description: Mathematics can serve many functions in physics. It can provide a computational system, reflect a physical idea, conveniently encode a rule, and so forth. A physics student thus has many different options for using mathematics in his physics problem solving. We present a short example from the problem solving work of upper level physics students and use it to illustrate the epistemic framing process: framing because these students are focusing on a subset of their total math knowledge, epistemic because their choice of subset relates to what they see (at that particular time) as the nature of the math knowledge in play. We illustrate how looking for the warrants students use, the often unspoken reasons they think their evidence supports their mathematical claims, serves as a window to their epistemic framing. These warrants provide a powerful, concise piece of evidence of their epistemic framing.

description: “Ibride” nasce da una ricerca sociologica e da un percorso di riflessione intrapreso durante un periodo di ricerca sul campo presso l’Istituto Nazionale Tumori Regina Elena di Roma tra il 2017 e il 2019. L’ibridazione, a cui il testo fa più volte riferimento, indica la mescolanza di elementi eterogenei e nel caso specifico vuole riferirsi al processo che si attiva quando le categorie biomediche entrano nel campo della vita quotidiana. Il caso del cancro al seno è emblematico in quanto ai grandi investimenti in ambito oncologico e all’enfasi crescente sulla prevenzione nel discorso pubblico corrisponde una densità dell’esperienza, di malattia e di genere, forse senza eguali. Ciò che emerge è che quando il rischio genetico, le tecniche di cura e di miglioramento del corpo, le rappresentazioni sociali, entrano nel campo delle scelte biografiche il processo di ibridazione tra natura e cultura, tra umano e non-umano assume contorni incerti e che meritano un maggiore approfondimento teorico ed empirico. La propensione, di matrice Actor Network Theory, a seguire il cancro nella sua complessità ha reso possibile l’incontro con le donne intervistate, con i loro corpi assemblati, deturpati, cibernetici, con i geni BRCA e i filamenti di DNA, approfondendo elementi di storia sociale della medicina, analizzando le rappresentazioni sociali e l’ambivalente attivismo delle sopravvissute.

description: Symmetries play a major role in identifying topological phases of matter and in establishing a direct connection between protected edge states and topological bulk invariants via the bulk-boundary correspondence. One-dimensional lattices are deemed to be protected by chiral symmetry, exhibiting quantized Zak phases and protected edge states, but not for all cases. Here, we experimentally realize an extended Su-Schrieffer-Heeger model with broken chiral symmetry by engineering one-dimensional zigzag photonic lattices, where the long-range hopping breaks chiral symmetry but ensures the existence of inversion symmetry. By the averaged mean displacement method, we detect topological invariants directly in the bulk through the continuous-time quantum walk of photons. Our results demonstrate that inversion symmetry protects the quantized Zak phase, but edge states can disappear in the topological nontrivial phase, thus breaking the conventional bulk-boundary correspondence. Our photonic lattice provides a useful platform to study the interplay among topological phases, symmetries, and the bulk-boundary correspondence.

The statist impulse : the case of Petro-Canada
Creators: name: Lawson, Brian J. (Brian John)
Publisher: name: University of British Columbia
Year: 2010

description: The Statist Impulse: The Case of Petro-Canada seeks to find cause for the establishment and phenomenal growth of Canada's National Petroleum Corporation. The study argues that Petro-Canada is part and parcel of an historically constituted statist dynamic common to all advanced capitalist countries. Utilizing Marxist theory, the thesis contends that statism serves to resolve the problems or failures of capitalist economies, and is an essential prerequisite for the growth of capital. Such was the case with Petro-Canada. The international oil crisis of the early seventies, which resulted in so much economic disorder and concern about future energy security, caused governments to increasingly turn to state enterprise, in the hope of filling their national petroleum needs. The statist impulse was furthered by the fact that the private oil companies, particularly in the eyes of .the majority of governments, failed to respond to the crisis adequately or satisfactorily. After an examination of the western industrialized nations growing reliance on state capitalist forms for obtaining energy security, the thesis investigates Petro-Canada in more detail. The study develops the point that Canada's vigorous public enterprise tradition played no small role in the crown corporation's creation and success. It is then argued that although the NDP and nationalist wave of the late 1960's spawned the concept of a Petro-Canada, the Liberals and Federal state singlehandedly implemented the proposal. The Government wholeheartedly embraced Petro-Canada, not for the sake of the NDP, but for reasons having to do with state capitalism. Through Petro-Canada's subsequent participation in numerous joint ventures, the state has socialized part of the private oil industry's exploration and development risk so as to prod the petroleum corporations into greater activity. But the crown corporation has also acted as a substitute for the petroleum giants in certain areas, such as crude importation, so as to protect energy dependent general capital. The study contends that from a position of outright hostility toward Petro-Canada, the private sector gradually accepted state intervention into petroleum because of the lucrative joint ventures. Accordingly, it is argued that the state acted autonomously in setting-up Petro-Canada, without the support of the Canadian bourgeoisie. Finally, the study looks at the Tory effort to dismantle Petro-Canada and concludes that statism, in the form of the National Petroleum Corporation, proved too potent a force for the Conservatives to tackle. The issue of 'privatization' politically isolated the Tories from the majority of Canadians and became such a contentious internal issue that it divided and paralyzed the Conservative Government. In the end, Petro-Canada helped defeat the Tories and symbolizes the victory of state-capitalism over anti-statism.

description: The scientific views upon life and death of Homo neanderthalensis, the closest species to Homo sapiens ever lived, changed continuously through time. Once considered a form of brutish, unintelligent and savage hominin, Neanderthals are now rightfully seen as a highly social, clever and ecologically plastic species, whose behavior must have been much closer to modern humans than we thought before. Extensive gene exchange between the two species and convincing evidence of imitation by Neanderthals of H. sapiens practices and technologies bolster this view, suggesting the interactions between the two were possibly untroubled. This casts serious doubts on the conventional opinion that H. sapiens could have violently exterminated Neanderthals. In contrast, the much stronger than ever evidence that Neanderthals were not a coldloving species, and an increased awareness of the effect of climate change on extinction in hominins, reinforce the idea that H. sapiens did not cause their demise.

description: The purpose of this thesis is to study the Balkan folk dance tradition in the region of Eastern Rumelia through the custom and dance of the anastenarides and its connection with the regions of central Macedonia. We initially examined the concept of folk tradition and folk culture through customs and traditions, always in relation to traditional dance. Then we studied the Balkan folk tradition and Balkan culture through the customary events in the Orthodox countries of the Balkans, mainly in Bulgaria and Greece. We also referred in detail to the custom of the anastenarides, through an analytical description of the custom, focusing more on the ritual part of the custom and mainly on the dance. Another topic we touched on was the folk dance tradition of the two regions, through the customs, traditions and folk events. Also listing the traditional dances of the region and the occasions in which they were danced, emphasizing the rich dance tradition of the region. Finally, we dealt with the presence of the custom in the area of Strandza and the relationship of the custom with the two regions of central Macedonia (Agia Eleni of Serres and Mavrolefki of Drama) today.

description: We demonstrate a new class of molecules for exceptional performance in molecular electronics and spintronics. Phenalenyl-based radicals are stable radicals whose electronic properties can be tuned readily by heteroatom substitution. We employ density functional theory-based non-equilibrium Green's function (NEGF-DFT) calculations to show that this class of molecules exhibits tunable spin- and charge-transport properties in single molecule junctions. Our simulations identify the design principles and interplay between unusually high conductivity and strong spin-filtering: Paired with moderate conductance ($10^{-3} G_0$), two of the four radicals investigated exhibit above 80% spin filter efficiency that is moreover tunable via bias control. Conversely, two radicals that make modest spin filters are excellent conductors with a low bias conductance reaching $0.48 G_0$. This is made possible by the unusually good alignment of the singly occupied or unoccupied molecular orbital with the Fermi level of the electrodes, overcoming the limitations of Fermi level pinning that typically plague molecular electronics. We show that this interplay between excellent conductance and high spin-filter efficiency is determined by the energy alignment between the singly (un)occupied molecular orbital and the Fermi level of the electrodes, and that for phenalenyls this can be readily controlled with judicious heteroatom substitution.

description: We propose orbital fluctuations in a multi-band ground state as the superconducting pairing mechanism in the new iron-based materials. We develop a general SU(4) theoretical framework for studying a two-orbital model and discuss a number of scenarios that may be operational within this orbital fluctuation paradigm. The orbital and spin symmetry of the superconducting order parameter is argued to be highly non-universal and dependent on the details of the underlying band structure. We introduce a minimal two-orbital model for the Fe-pnictides characterized by non-degenerate orbitals that strongly mix with each other. They correspond to the iron "d_xy" orbital and to an effective combination of "d_zx" and "d_zy", respectively. Using this effective model we perform RPA calculations of susceptibilities and effective pairing interactions. We find that spin and orbital fluctuations are, generally, strongly coupled and we identify the parameters that control this coupling as well as the relative strength of various channels.

In our experiments, we find that such character-level models cut the number of untranslated words by over 40% and are especially competitive (improvements of 2-3 BLEU points) in the case of limited training data. We explore the impact of character alignment, phrase table filtering, bitext size and the choice of pivot language on translation quality. We further compare cascaded translation models to the use of synthetic training data via multiple pivots, and we find that the latter works significantly better. Finally, we demonstrate that neither word-nor character-BLEU correlate perfectly with human judgments, due to BLEU's sensitivity to length.

description: Falls among older adult patients in the hospital setting are a critical issue. In the project hospital, the number of older adult patient falls increased over the last three years. Existing evidence shows that mobilization of patients prevents functional decline and muscle loss. One fall prevention strategy is to promote early mobilization. A nursing mobility protocol can assist nursing staff to implement early, and continuous mobility interventions based on the patients assessed functional status. This performance improvement project included conducting surveys of registered nurses’ and nursing aides’ perceptions regarding fall prevention and promotion of early mobility. In collaboration with the hospital’s education and physical therapy departments and current best practices, an early mobility protocol was adapted from the existing hospital protocol. Staff members were educated and trained on the protocol before implementation. Data analysis consisted of the evaluation of existing data and survey results before and after the implementation of the mobility protocol. The data were analyzed from the hospital’s existing aggregated reports. The data included fall rates, the length of hospital stay, physical therapy referrals, and mobility activities. Data collected and analyzed demonstrated a significant increase (t(24.40) = -5.46, p < .001) in patient mobility activities. There was one fall during the study period which may have been contributed to increased patient acuity and limited nursing aide staff. There were no falls with injury noted. Therefore, a mobility protocol has the potential to iv improve patient outcomes by guiding nursing care and empowering nurses to assist with and direct patient mobility activities.

description: We present the discovery of a Baldwin effect in 8 nearby Seyfert galaxies for the three most prominent mid-infrared forbidden emission lines observable from the ground that are commonly found in AGN, [ArIII](8.99 micron), [SIV](10.51 micron), and [NeII](12.81 micron). The observations were carried out using the VLT/VISIR imager and spectroraph at the ESO/Paranal observatory. The bulk of the observed line emission comes from the inner <0.4 arcsec which corresponds to spatial scales <100 pc in our object sample. The correlation index is approximately -0.6 without significant difference among the lines. This is the strongest anti-correlation between line equivalent width and continuum luminosity found so far. In the case of Circinus, we show that despite the use of mid-infrared lines, obscuration by either the host galaxy or the circumnuclear dust torus might affect the equivalent widths. Given the small observed spatial scales from which most of the line emission emanates, it is unclear how these observations fit into the favored "disappearing NLR'' scenario for the narrow-line Baldwin effect.

Interband, intraband and excited-state direct photon absorption of silicon and germanium nanocrystals embedded in a wide band-gap lattice

description: Embedded Si and Ge nanocrystals (NCs) in wide band-gap matrices are studied theoretically using an atomistic pseudopotential approach. From small clusters to large NCs containing on the order of several thousand atoms are considered. Effective band-gap values as a function of NC diameter reproduce very well the available experimental and theoretical data. It is observed that the highest occupied molecular orbital for both Si and Ge NCs and the lowest unoccupied molecular orbital for Si NCs display oscillations with respect to size among the different irreducible representations of the $C_{3v}$ point group to which these spherical NCs belong. Based on this electronic structure, first the interband absorption is thoroughly studied which shows the importance of surface polarization effects that significantly reduce the absorption when included. This reduction is found to increase with decreasing NC size or with increasing permittivity mismatch between the NC core and the host matrix. Reasonable agreement is observed with the experimental absorption spectra where available. The deformation of spherical NCs into prolate or oblate ellipsoids are seen to introduce no pronounced effects for the absorption spectra. Next, intraconduction and intravalence band absorption coefficients are obtained in the wavelength range from far-infrared to visible region. These results can be valuable for the infrared photodetection prospects of these NC arrays. Finally, excited-state absorption at three different optical pump wavelengths, 532 nm, 355 nm and 266 nm are studied for 3- and 4 nm-diameter NCs. This reveals strong absorption windows in the case of holes and a broad spectrum in the case of electrons which can especially be relevant for the discussions on achieving gain in these structures.

description: We show that for tripartite quantum pure states of qubits, all the kinds of entanglement in terms of SLOCC classification are experimentally measurable by simple projective measurements, provided that four copies of the composite quantum system are available. In particular, the entanglement of reduced density matrices, even though they are mixed states, can be exactly determined in experiment. Concurrence of assistance is also shown to be measurable by introducing an interesting equations with explicit physical meanings.

Translating from Morphologically Complex Languages: A Paraphrase-Based Approach

description: We propose a novel approach to translating from a morphologically complex language. Unlike previous research, which has targeted word inflections and concatenations, we focus on the pairwise relationship between morphologically related words, which we treat as potential paraphrases and handle using paraphrasing techniques at the word, phrase, and sentence level. An important advantage of this framework is that it can cope with derivational morphology, which has so far remained largely beyond the capabilities of statistical machine translation systems. Our experiments translating from Malay, whose morphology is mostly derivational, into English show significant improvements over rivaling approaches based on five automatic evaluation measures (for 320,000 sentence pairs; 9.5 million English word tokens).

description: We present work on sentiment analysis in Twitter for Macedonian. As this is pioneering work for this combination of language and genre, we created suitable resources for training and evaluating a system for sentiment analysis of Macedonian tweets. In particular, we developed a corpus of tweets annotated with tweet-level sentiment polarity (positive, negative, and neutral), as well as with phrase-level sentiment, which we made freely available for research purposes. We further bootstrapped several large-scale sentiment lexicons for Macedonian, motivated by previous work for English. The impact of several different pre-processing steps as well as of various features is shown in experiments that represent the first attempt to build a system for sentiment analysis in Twitter for the morphologically rich Macedonian language. Overall, our experimental results show an F1-score of 92.16, which is very strong and is on par with the best results for English, which were achieved in recent SemEval competitions.

description: Some early-type galaxies show a correlation between color and integrated magnitude among the brighter metal-poor globular clusters (GCs). This phenomenon, known as the blue tilt, implies a mass-metallicity relationship among these clusters. In this paper we show that self-enrichment in GCs can explain several aspects of the blue tilt, and discuss predictions of this scenario.

description: We develop an algorithm of polynomial complexity for evaluating one-loop amplitudes with an arbitrary number of external particles. The algorithm is implemented in the Rocket program. Starting from particle vertices given by Feynman rules, tree amplitudes are constructed using recursive relations. The tree amplitudes are then used to build one-loop amplitudes using an integer dimension on-shell cut method. As a first application we considered only three and four gluon vertices calculating the pure gluonic one-loop amplitudes for arbitrary external helicity or polarization states. We compare our numerical results to analytical results in the literature, analyze the time behavior of the algorithm and the accuracy of the results, and give explicit results for fixed phase space points for up to twenty external gluons.

description: We give a presentation of Pure type systems where contexts need not be well-formed and show that this presentation is equivalent to the usual one. The main motivation for this presentation is that, when we extend Pure type systems with computation rules, like in the logical framework Dedukti, we want to declare the constants before the computation rules that are needed to check the well-typedness of their type.

Constraining Orbital Parameters Through Planetary Transit Monitoring

description: The orbital parameters of extra-solar planets have a significant impact on the probability that the planet will transit the host star. This was recently demonstrated by the transit detection of HD 17156b whose favourable eccentricity and argument of periastron dramatically increased its transit likelihood. We present a study which provides a quantitative analysis of how these two orbital parameters affect the geometric transit probability as a function of period. Further, we apply these results to known radial velocity planets and show that there are unexpectedly high transit probabilities for planets at relatively long periods. For a photometric monitoring campaign which aims to determine if the planet indeed transits, we calculate the expected transiting planet yield and the significance of a potential null result, as well as the subsequent constraints that may be applied to orbital parameters.
