description: Pathogens can be transported by water through soil to contaminate distant crops. The California LGMA states that leafy green crops within 30ft of flooded soil should be destroyed due to potential contamination. Previously flooded areas should not be replanted for 60 days. This study investigated the transport of Salmonella enterica and Citrobacter freundii through soil in a model system with a positive slope (uphill). Field trials involving flooding one end of a spinach bed with a negative slope (downhill) with water containing Escherichia coli were also conducted. Soil type, soil moisture content, and slope affected bacterial movement. In field trials, E. coli was quickly transported to the 30ft boundary, and persisted significantly longer in the fall trial than the spring. These data suggest the LGMA metrics need to provide additional parameters to prevent the harvest of leafy green crops potentially contaminated by floodwater.

description: Billiard systems, broadly speaking, may be regarded as models of mechanical systems in which rigid parts interact through elastic impulsive (collision) forces. When it is desired or necessary to account for linear/angular momentum exchange in collisions involving a spherical body, a type of billiard system often referred to as no-slip has been used. In recent work, it has become apparent that no-slip billiards resemble non-holonomic mechanical systems in a number of ways. Based on an idea by Borisov, Kilin and Mamaev, we show that no-slip billiards very generally arise as limits of non-holonomic (rolling) systems, in a way that is akin to how ordinary billiards arise as limits of geodesic flows through a flattening of the Riemannian manifold.

Pharmacokinetics, tissue distribution and serum protein binding of (E,Z)-2,3’-diene VPA in rats
Creators: name: Moshenko, Janice Lynn
Publisher: name: University of British Columbia
Year: 2009

description: Valproic acid (VPA) is a broad spectrum anticonvulsant drug presently used for the management of various seizure disorders. Despite its reputation for being a relatively safe antiepileptic, it has been characterized by two potentially fatal side effects, namely hepatotoxicity and teratogenicity. Hence, the development of analogues of VPA lacking the toxic side effects but possessing the desired attributes of conventional anticonvulsants would be of great benefit therapeutically. One interesting observation with VPA therapy is a delayed anticonvulsant effect that occurs after discontinuation of VPA and after VPA has been cleared from the systemic circulation. Since VPA is extensively metabolized and its metabolites have been shown to possess anticonvulsant activity, the possibility exists that one or more of VPA's active metabolites may be contributing to the prolongedpharmacological activity of VPA. One such metabolite, (E,Z)-2,3'-diene VPA, has been of interest in our laboratory. This diene was preferentially found in rat brain after administration of VPA. Preliminary investigations with this compound demonstrated that it possessed equivalent anticonvulsant activity to VPA using the PTZ seizure test in rats and mice, and minimal muscle spasticity and sedative effects when compared to VPA. These studies suggested that this diene may have potential as an alternative medication to VPA. Therefore, investigations into the pharmacokinetics and disposition of (E,Z)-2,3'-diene VPA in rats were conducted in order to assess the diene's contributions to VPA activity and its potential as an alternative medication to VPA.

description: A series of four cascading basins were installed at Hambleton Creek Farm in Chestertown, Maryland to treat agricultural stormwater from a 45.4 ha watershed.  The basins drain into Hambleton Creek, a tributary of the Chesapeake Bay.  The basin system was monitored for 22 months from July 2013 to April 2015 for concentrations and mass loads of suspended sediments, phosphorous and nitrogen.  Over the duration of the study, 27 storm events were successfully sampled and tested.  During this time, the basin system provided statistically significant reductions of sediments, total phosphorus and total nitrogen mass loads.  The total volume reduction exhibited by the system was 56%; volume reduction appears to be the main mechanism of removal for suspended sediments, phosphorus, and nitrogen.  Total mass reductions based on an input/output approach for suspended solids, total phosphorus and total nitrogen were 65%, 59%, and 64%, respectively.

description: We propose a method for broadband long-wavelength photodetection using the nonlinear Hall effect in non-centrosymmetric quantum materials. The inherently quadratic relation between transverse current and input voltage at zero magnetic field is used to rectify the incident terahertz or infrared electric field into a direct current, without invoking any diode. Our photodetector operates at zero external bias with fast response speed and has zero threshold voltage. Remarkably, the intrinsic current responsivity due to Berry curvature mechanism is a material property independent of the incident frequency or the scattering rate, which can be evaluated from first-principles electronic structure calculations. We identify the Weyl semimetal NbP for terahertz photodection with large current responsivity reaching $\sim 1$A/W without external bias.

description: We study in detail a particular statistical method in genetic case-control analysis, labeled "genotype-based association", in which the two test results from assuming dominant and recessive model are combined in one optimal output. This method differs both from the allele-based association which artificially doubles the sample size, and the direct chi-square test on 3-by-2 contingency table which may overestimate the degree of freedom. We conclude that the comparative advantage (or disadvantage) of the genotype-based test over the allele-based test mainly depends on two parameters, the allele frequency difference delta and the Hardy-Weinberg disequilibrium coefficient difference delta_epsilon. Six different situations, called "phases", characterized by the two X^2 test statistics in allele-based and genotype-based test, are well separated in the phase diagram parameterized by delta and delta_epsilon. For two major groups of phases, a single parameter theta = tan^-1 (delta/delta_epsilon) is able to achieves an almost perfect phase separation. We also applied the analytic result to several types of disease models. It is shown that for dominant and additive models, genotype-based tests are favored over allele-based tests.

description: We study the effective field theory (including operators up to dimension five) of models in which dark matter is composite, consisting of either an electroweak doublet Dirac fermion (`higgsino-like dark matter') or an electroweak triplet Majorana fermion (`wino-like dark matter'). Some of the dimension-five operators in the former case cause mass splittings between the neutralino and chargino states, leading to a depleted rate of coannihilations and viable thermal relic dark matter with masses of the order of tens to hundreds of GeV rather than the usual pure higgsino thermal relic mass of 1 TeV. No such effects are found in the latter case (where the usual thermal relic mass is 3 TeV). Other operators, present for both wino- and higgsino-like dark matter, correspond to inelastic electromagnetic dipole moment interactions and annihilation through these can lead to viable models with dark matter masses up by an order of magnitude compared to the usual values.

We use both a stochastic and a continuous framework to treat these interactions and compare the flux of tau leptons propagated after some amount of matter. We discuss the accuracy of the approximation of continuous energy losses by studying the propagation in standard rock of taus with both mono-energetic and power law injection spectra.

description: Reservoir Computing (RC) is an appealing approach in Machine Learning that combines the high computational capabilities of Recurrent Neural Networks with a fast and easy training method. Likewise, successful implementation of neuro-inspired plasticity rules into RC artificial networks has boosted the performance of the original models. In this manuscript, we analyze the role that plasticity rules play on the changes that lead to a better performance of RC. To this end, we implement synaptic and non-synaptic plasticity rules in a paradigmatic example of RC model: the Echo State Network. Testing on nonlinear time series prediction tasks, we show evidence that improved performance in all plastic models are linked to a decrease of the pair-wise correlations in the reservoir, as well as a significant increase of individual neurons ability to separate similar inputs in their activity space. Here we provide new insights on this observed improvement through the study of different stages on the plastic learning. From the perspective of the reservoir dynamics, optimal performance is found to occur close to the so-called edge of instability. Our results also show that it is possible to combine different forms of plasticity (namely synaptic and non-synaptic rules) to further improve the performance on prediction tasks, obtaining better results than those achieved with single-plasticity models.

description: New physics results with identified particles at STAR are presented. Measurements at low $p_T$ address bulk properties of the collision, while those at high $p_T$ address jet energy loss in the bulk matter produced. Between these extremes, measurements at intermediate $p_T$ address the interplay between jets and the bulk. We highlight: measurements of $v_2$ fluctuations as a new, sensitive probe of the initial conditions and the equation of state; correlations involving multi-strange particles, along with ratios of identified particles to test coalescence as a mechanism of particle production at intermediate $p_T$; three particle azimuthal correlation to search for conical emission; and the energy and particle-type dependence of hadron production at high $p_T$ to study quark and gluon jet energy loss.

description: We examined the effect of toroidal magnetic fields on a viscous gaseous disk around a central object under an advection dominated stage. We found self-similar solutions for radial infall velocity, rotation velocity, sound speed, with additional parameter $β$ [$=c_{\rm A}^2/(2c_{\rm s}^2)$], where $c_{\rm A}$ is the Alfvén speed and $c_{\rm s}$ is the isothermal sound speed. Compared with the non-magnetic case, in general the disk becomes thick due to the magnetic pressure, and the radial infall velocity and rotation velocity become fast. In a particular case, where the magnetic field is dominant, on the other hand, the disk becomes to be magnetically supported, and the nature of the disk is significantly different from that of the weakly magnetized case.

description: We study how impurities influence the current-induced dynamics of magnetic Skyrmions moving in a racetrack geometry. For this, we solve numerically the generalized Landau-Lifshitz-Gilbert equation extended by the current-induced spin transfer torque. In particular, we investigate two classes of impurities, non-conducting and magnetic impurities. The former are magnetically rigid objects and yield to an inhomogeneous current density over the racetrack which we determine separately by solving the fundamental electrostatic equations. In contrast, magnetic impurities leave the applied current density homogeneous throughout the stripe. Depending on parameters, we observe four different scenarios of Skyrmion motions in the presence of disorder, the Skyrmion decay, the pinning, the creation of additional Skyrmions, and ordinary Skyrmion passage. We calculate and discuss phase diagrams in dependence of the impurity concentration and radii of the impurities.
Unlocking the Potential of N-O Bonds in Organic Synthesis

Subjects: Uncategorized

description: This thesis examines various aspects of harnessing the reactivity of N-O bond-containing molecules toward useful synthetic organic chemistry. In each chapter, the key to this challenge lies in the careful formation of energetic molecules containing N-O bonds and the controlled release of that energy toward driving the transformation of interest. To achieve this goal, high-throughput experimentation has been employed throughout the course of this research in order to maximize productivity and learning while simultaneously minimizing time and material requirements. Enabled by these tools, this thesis is the result of almost 14,000 experiments. Chapter 1 describes the iron-catalyzed synthesis of indoles from ortho-nitrostyrenes. Mechanistic studies revealed that the iron-phenanthroline catalyst serves to shuttle oxygen atoms from nitro groups to silanes in order to generate reactive ortho-nitrosostyrenes, which then undergo spontaneous 6π-electrocyclization and subsequent reduction to give indoles. Chapter 2 describes the synthesis of furo[2,3-b]indolines from N-hydroxyindoles in a reaction cascade sequence. Key reactive N-alkenyloxyindole intermediates are formed from conjugate addition of N-hydroxyindoles to activated alkynes with catalytic base, and then spontaneously undergo [3,3]-sigmatropic rearrangement and cyclization to form the product heterocycles. Chapter 3 describes the mechanistic study of solvent effects on the [1,4]-4π-electrocyclizations of N-alkenylnitrones and the development of the first example of a catalytic asymmetric [1,4]-4π-electrocyclization. Eyring analysis of activation parameters for the thermal electrocyclization of N-alkenylnitrones was conducted in order to identify solvents with minimal background reactivity that can also solubilize the cationic (MeCN)4Pd(BF4)2 / phosphine catalysts needed to promote enantioselective [1,4]-4π-electrocyclization to form 2,3-dihydroazete-N-oxide products.

description: Quantum imaging can beat classical resolution limits, imposed by diffraction of light. In particular, it is known that one can reduce the image blurring and increase the achievable resolution by illuminating an object by entangled light and measuring coincidences of photons. If an $n$-photon entangled state is used and the $n$th-order correlation function is measured, the point-spread function (PSF) effectively becomes $\sqrt n$ times narrower relatively to classical coherent imaging. Quite surprisingly, measuring $n$-photon correlations is not the best choice if an $n$-photon entangled state is available. We show that for measuring $(n-1)$-photon coincidences (thus, ignoring one of the available photons), PSF can be made even narrower. This observation paves a way for a strong conditional resolution enhancement by registering one of the photons outside the imaging area. We analyze the conditions necessary for the resolution increase and propose a practical scheme, suitable for observation and exploitation of the effect.

description: It has been asked by different authors whether the two classes of Schatten-$p$-norm-based functionals $C_p(ρ)=\min_{σ\in\mathcal{I}}||ρ-σ||_p$ and $ \tilde{C}_p(ρ)= \|ρ-Δρ\|_{p}$ with $p\geq 1$ are valid coherence measures under incoherent operations, strictly incoherent operations, and genuinely incoherent operations, respectively, where $\mathcal{I}$ is the set of incoherent states and $Δρ$ is the diagonal part of density operator $ρ$. Of these questions, all we know is that $C_p(ρ)$ is not a valid coherence measure under incoherent operations and strictly incoherent operations, but all other aspects remain open. In this paper, we prove that (1) $\tilde{C}_1(ρ)$ is a valid coherence measure under both strictly incoherent operations and genuinely incoherent operations but not a valid coherence measure under incoherent operations, (2) $C_1(ρ)$ is not a valid coherence measure even under genuinely incoherent operations, and (3) neither ${C}_{p>1}(ρ)$ nor $\tilde{C}_{p>1}(ρ)$ is a valid coherence measure under any of the three sets of operations. This paper not only provides a thorough examination on the validity of taking $C_p(ρ)$ and $\tilde{C}_p(ρ)$ as coherence measures, but also finds an example that fulfills the monotonicity under strictly incoherent operations but violates it under incoherent operations.

description: A single set of material properties was developed to describe the pyrolysis of fiberglass reinforced polyester composites at multiple composition ratios. Milligram-scale testing was performed on the unsaturated polyester (UP) resin using thermogravimetric analysis (TGA) coupled with differential scanning calorimetry (DSC) to establish and characterize an effective semi-global reaction mechanism, of three consecutive first-order reactions. Radiation-driven gasification experiments were conducted on UP resin and the fiberglass composites at compositions ranging from 41 to 54 wt% resin at external heat fluxes from 30 to 70 kW m-2. The back surface temperature was recorded with an infrared camera and used as the target for inverse analysis to determine the thermal conductivity of the systematically isolated constituent species. Manual iterations were performed in a comprehensive pyrolysis model, ThermaKin. The complete set of properties was validated for the ability to reproduce the mass loss rate during gasification testing.

description: Streptococcus suis (S. suis) is an emerging zoonosis and a leading cause of adult bacterial meningitis in many developing countries. The disease is endemic in Southeast Asia mainly affecting men of working age. In Thailand, S. suis infection is an important health issue and one of the most common causes of bacterial meningitis with a high prevalence in the northern region due to cultural food habits involving consumption of raw pork. To date, much uncertainty remains regarding the understanding of S. suis clinical manifestations and treatment responses as well as gaps between different settings. This Ph.D project aimed to explore insights on risk factors, clinical manifestations and outcomes of S. suis infection as well as to quantify the burden of disease and its economic impact on years of life lost, quality of life and work productivity in Thailand.

description: Adoptive cell transfer therapy (ACT) is one of the most promising immunotherapies against cancer. However, this treatment regimen requires the expansion of a small population of effector cells, known as tumor infiltrating lymphocytes, into the billions in order to overcome the immunosuppressive tumor microenvironment. The cytotoxic T lymphocytes (CTLs) within this invading immune cell population are the most critical components to kill the growing cancer cells. Nonetheless, the rapid expansion of already exhausted tumor-infiltrating cytotoxic T lymphocytes (TICTLs) may further push them to a terminally differentiated state that reduces their proliferative response upon antigen stimulation. Recently, induced pluripotent stem cells (iPSCs) generated from TICTLs have been suggested as a way to create a renewable source of rejuvenated tumor-specific CTLs, but retroviral reprogramming is inefficient, and can lead to an increased chance of tumorigenesis. To improve the expansion of TICTLs, we used transient protein exposure to SOX2, OCT4, and NANOG (SON) in order to push these exhausted TICTLs to a less differentiated stage, preferably stem cell-like memory CTLs (Tscm). These three transcription factors were transiently delivered using a nuclear protein delivery system. We found only the TICTLs treated with SON (STICTLs) exhibited an increased proliferation rate and extended survivability, independent of additional cytokines and antigen stimulation both in vitro and in vivo; effector CTLs did not respond to the SON regimen. These highly proliferative STICTLs could be associated with up regulation of certain genes related in cell cycle control, such as cyclin D1. Though these STICTLs still express a T cell receptor (TCR), as well as many critical downstream components, they were unable to elicit a reaction against antigen exposure. Though clearly not iPSCs, it is possible that the SON treatment had pushed the TICTLs into a state similar to an early double negative thymocyte. Our findings indicate that TICTLs are uniquely responsive to protein SON compared to naïve and effector CTLs; suggesting TICTLs may also be sensitive to regulation by other more lineage specific transcription factors, thus present new avenue for cancer immune therapy.

description: Massive outflows of neutral atomic hydrogen (HI) have been observed in absorption in a number of radio galaxies and are considered a signature of AGN feedback. These outflows on kpc-scales have not been investigated in great detail as they require high-angular resolution observations to be spatially resolved. In some radio AGN, they are likely the result of the radio jets interacting with the interstellar medium. We have used a global VLBI array to map the HI outflow in a small sample of young and restarted radio galaxies which we previously observed with the VLA and the WSRT at lower resolution. Here, we report on our findings for 4C52.37 and 3C293 and we discuss the sample including the previously published sources 4C12.50 and 3C236. For 4C52.37, we present the first-ever HI VLBI observation which recovered the majority of the outflowing HI gas in form of clouds towards the central 100pc of the AGN. The clouds are blue-shifted by up to 600km/s with respect to the systemic velocity. 3C293 is largely resolved out in our VLBI observation, but we detect, towards the VLBI core, some outflowing HI gas blueshifted with respect to the systemic velocity by up to 300km/s. We also find indications that the HI outflow is extended. Overall, we find that the fraction of HI gas recovered by our VLBI observation varies significantly within our sample. In all cases we find evidence for a clumpy structure of both the outflowing and the quiescent gas, consistent with predictions from numerical simulations. The outflows include at least a component of relatively compact clouds (10^4-10^5Msun) often observed already at a few tens of pc (in projection) from the core. We also find indications that the HI outflow might have a diffuse component, especially in larger sources. Our results support the interpretation that we observe these AGNs at different stages in the evolution of the jet-ISM interaction.

description: We report on an extraordinary field effect of the superconducting LaAlO3/KTaO3(111) interface with Tc ~2 K. By applying a gate voltage (VG) across KTaO3, the interface can be continuously tuned from superconducting into insulating states, yielding a dome-shaped Tc-VG dependence. The electric gating has only a minor effect on carrier density as evidenced in the Hall-effect measurement, while it changes spatial profile of the carriers in the interface, hence the carrier's disorder level significantly. As temperature is decreased, the resistance saturates at lowest temperature in both superconducting and insulating sides, despite an initial dramatic dropping or increasing, which suggests an emergence of quantum metallic state associated with failed superconductor and/or fragile insulator. A VG-modulation of the magnetic-field-driven superconductor to insulator quantum phase transition reveals a non-universal criticality.

description: We study the spectrum and eigenstates of the quantum discrete Bose-Hubbard Hamiltonian in a finite one-dimensional lattice containing two bosons. The interaction between the bosons leads to an algebraic localization of the modified extended states in the normal mode space of the noninteracting system. Weight functions of the eigenstates in the space of normal modes are computed by using numerical diagonalization and perturbation theory. We find that staggered states do not compactify in the dilute limit for large chains.

On the Formalism of The Screening Paradox
Creators: name: Balayla, Jacques
Publisher: name: arXiv
Year: 2020
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: Bayes' Theorem imposes inevitable limitations on the accuracy of screening tests by tying the test's predictive value to the disease prevalence. The aforementioned limitation is independent of the adequacy and make-up of the test and thus implies inherent Bayesian limitations to the screening process itself. As per the WHO's $Wilson-Jungner$ criteria, one of the prerequisite steps before undertaking screening is to ensure that a treatment for the condition screened exists. However, in so doing, a paradox, henceforth termed the screening paradox, ensues. If a disease process is screened for and subsequently treated, its prevalence would drop in the population, which as per Bayes' theorem, would make the tests' predictive value drop in return. Put another way, a very powerful screening test would, by performing and succeeding at the very task it was developed to do, paradoxically reduce its ability to correctly identify individuals with the disease it screens for in the future. Where $J$ is Youden's statistic (sensitivity [$a$] + specificity [$b$] - 1), and $ϕ$ is the prevalence, the ratio of positive predictive values at subsequent time $k$, $ρ(ϕ_{k})$, over the original $ρ(ϕ_{0})$ at $t_0$ is given by: $ζ(ϕ_{0},k) = \frac{ρ(ϕ_{k})}{ρ(ϕ_{0})} =\frac{ϕ_k(1-b)+Jϕ_0ϕ_k}{ϕ_0(1-b)+Jϕ_0ϕ_k}$ In this manuscript, we explore the mathematical model which formalizes said screening paradox and explore its implications for population level screening programs. In particular, we define the number of positive test iterations (PTI) needed to reverse the effects of the paradox as follows: $n_{iϕ_e}=\left\lceil\frac{ln\left[\frac{ωϕ_eϕ_k-ωϕ_e}{ωϕ_eϕ_k-ϕ_k}\right]}{2lnω}\right\rceil$ where $ω$ is the square root of the positive likelihood ratio (LR+).

description: One derives the governing equations and the Rankine - Hugoniot conditions for a mixture of two miscible fluids using an extended form of Hamilton's principle of least action. The Lagrangian is constructed as the difference between the kinetic energy and a potential depending on the relative velocity of components. To obtain the governing equations and the jump conditions one uses two reference frames related with the Lagrangian coordinates of each component. Under some hypotheses on flow properties one proves the hyperbolicity of the governing system for small relative velocity of phases.

description: Biological macromolecules like proteins, DNA and polysaccharides, as well as many industrial polymers, are classified as polyelectrolytes, for in solution, the repeat units in their backbone have charge-bearing groups, surrounded by a cloud of counter-ions. Many polyelectrolytes are used as rheology modifiers in paints, pharmaceuticals, and cosmetics. Understanding of, and control over, the influence of added polyelectrolytes on complex free surface flows encountered in printing as well as spraying, dispensing, and microfluidic drops formation are both scientifically and technologically significant problems. Quantitative studies of capillary-driven thinning and pinch-off dynamics of semidilute polyelectrolyte solutions, and their response to extensional flows are relatively rare, and are the focus of this contribution. Here the pinch-off dynamics and extensional rheology of three model polyelectrolytes: poly(sodium 4-styrenesulfonate) (NaPSS), poly(acrylic acid) (PAA), and sodium carboxymethyl cellulose (NaCMC) in different solvents and ionic systems are characterized by using Dripping-onto-Substrate rheometry. Unlike shear relaxation time that decreases with increasing concentration for unentangled, semidilute solutions, the extensional relaxation time of PAA increases with an exponent of 1/2 and exhibits 3/2 for entangled systems. The specific viscosity of all three polymers show higher sensitivity to salt and glycerol in semidilute unentangled solutions compared to entangled systems, whereas the influence on extensional relaxation time and viscosity is less prominent. Using NaPSS in glycerol/water, we show that the specific viscosity and extensional relaxation time values obtained on addition of salt normalized by their salt-free value converge to universal master-curves if plotted as a function of ratio of salt concentration to molar concentration of monomers. Lastly, we find that the addition of glycerol changes the concentration-dependent increase in specific viscosity, and overall change in extensional viscosity due to corresponding changes in dielectric constant and solvent viscosity. The experiments and analysis show how the interplay of stretching due to electrostatics and hydrodynamics influence the shear and extensional rheology response as well as pinching dynamics and processability of polyelectrolyte dispersions. This contribution details how the influence of polymer (type, concentration, molecular weight), salt and solvent affect the rheology of polyelectrolyte dispersions and is expected to help in advancements of macromolecular engineering of multicomponent formulations.

description: We report on crystal structure, magnetic and thermal physical properties of EuPd$_2$Sn$_4$ stannide. From the magnetic susceptibility measurements a divalent state of Eu rare earth element was determined together with an antiferromagnetic (AFM) order at 11 K. By applying magnetic field, the magnetic behavior variation reveals a complex magnetic structure. Above a critical field Bc a ferromagnetic (FM)-like character starts to prevail. AFM and FM regimes are separated by a metamagnetic region. Heat capacity measurements confirm this behavior.

description: This article reports an automated approach to the evaluation of higher-order terms of QED perturbation to anomalous magnetic moments of charged leptons by numerical means. We apply this approach to tenth-order correction due to a particular subcollection of Feynman diagrams, which have no virtual lepton loops. This set of diagrams is distinctive in that it grows factorially in number as the order increases, and also each of the diagrams holds quite a large number of subtraction terms to be treated along renormalization procedure. Thus some automated scheme has long been required to evaluate correctly this class of diagrams. We developed a fast algorithm and an implementation which automates necessary steps to generate from the representation of each Feynman diagram the FORTRAN codes for numerical integration. Currently those diagrams of tenth order are being evaluated.

description: Explainable Artificial Intelligence (XAI) systems, including intelligent agents, must be able to explain their internal decisions, behaviours and reasoning that produce their choices to the humans (or other systems) with which they interact. In this paper, we focus on how an extended model of BDI (Beliefs-Desires-Intentions) agents can be able to generate explanations about their reasoning, specifically, about the goals he decides to commit to. Our proposal is based on argumentation theory, we use arguments to represent the reasons that lead an agent to make a decision and use argumentation semantics to determine acceptable arguments (reasons). We propose two types of explanations: the partial one and the complete one. We apply our proposal to a scenario of rescue robots.

Re-membering the Commercial Hotel in Edmonton, Alberta
Creators: name: Lintott, Christine Anne
Publisher: name: University of British Columbia

description: This Thesis Project is about remembrance and its embodiment in the retention of the physical history of place. That history is both individual and collective, oscillating through time, admitting the present into the past and the past into the future. The Project reflects upon the physical artifact and the circumstances of place which are its own history. Projected upon this reflection is the human experience of that artifact and of that place. In addition, within the realm of the artifact, exists the systemic, an interrelationship between and within which induces a conceptual and physiological layering. The systemic, in turn, has a temporal aspect which engages both of the focal ideas, memory and history. The figures which follow record the transformation (or remembering) of an existing Hotel structure, known as the Commercial Hotel, located in the Old Strathcona district of Edmonton. The program reinvents the existing hotel, bar, restaurant and retail components into a more intensive layering, or system, of variable accommodation, pub, micro brewery, restaurant and performance venue. The existing artifact is an armature for this reinvention, woven into the project additions, reassessing relationships to wall, vertical separation, and inside versus outside. The Project configures itself as having a strong street edge along the main thoroughfare of Strathcona, Whyte Avenue, consistent with the morphological history of this place, which is penetrated by a formal passage through the site. The passage opens up into a performance court, previously a parking lot, which is an extension of the pub and restaurant, and an opportunity for the site to intimately engage the variety of festivals which the Old Strathcona neighbourhood annually hosts. The site becomes a destination of multiplicity, beyond the established renown of the Commercial Hotel as a Jazz and Blues venue. In addition, this multiplicity is embodied by the opening up of the internal system of the existing building, through the vertical penetration of the brewery component. Thus, the systemic of relationships is continuously engaged within the memory of the artifact.
