description: We demonstrate the utility of dendrograms at representing the essential features of the hierarchical structure of the isosurfaces for molecular line data cubes. The dendrogram of a data cube is an abstraction of the changing topology of the isosurfaces as a function of contour level. The ability to track hierarchical structure over a range of scales makes this analysis philosophically different from local segmentation algorithms like CLUMPFIND. Points in the dendrogram structure correspond to specific volumes in data cubes defined by their bounding isosurfaces. We further refine the technique by measuring the properties associated with each isosurface in the analysis allowing for a multiscale calculation of molecular gas properties. Using COMPLETE 13CO(1-0) data from the L1448 region in Perseus and mock observations of a simulated data cube, we identify regions that have a significant contribution by self-gravity to their energetics on a range of scales. We find evidence for self-gravitation on all spatial scales in L1448 though not in all regions. In the simulated observations, nearly all of the emission is found in objects that would be self-gravitating if gravity were included in the simulation. We reconstruct the size-line width relationship within the data cube using the dendrogram-derived properties and find it follows the standard relation: s_v ~ R^0.58. Finally, we show that constructing the dendrogram of CO J=1-0 emission from the Orion-Monoceros region allows for the identification of giant molecular clouds in a blended molecular line data set using only a physically motivated definition (self-gravitating clouds with masses 5x10^4 Msun.

description: Software engineering best practices favour the creation of better quality projects, where similar projects should originate from similar layout, also called software templates. This approach greatly enhances project comprehension and reduces developers’ effort in the implementation of high-quality code. As an example, reproducibility and reusability are the key aspects of this software engineering process, the use of packaging tools and containers is a common practice to achieve robustness and portability for long-term software maintenance. However, these tools are not always easy to use and require a certain level of expertise to implement from scratch. Software templates are known to be an excellent way to reduce the complexity load on the use of such tools on the developer’s side.

There exist various tools to create such templates and routinely generate projects from them. One such Open Source tool is cookiecutter [1], a cross-platform command-line utility where a new project is replicated according to a set of files and directories that are pre-configured to provide the base structure. These templates, or cookiecutters, can be re-used and freely hosted on software version control platforms e.g. GitHub, where customization is achieved by filling in placeholders in the template files using project-specific values.

In this contribution, we show you how to develop custom modules within the AI4OS dashboard and make use of the best software development practices for this scientific framework. We present a new service that provides a collection of best templates on a marketplace/hub and use them to generate new projects on-fly through a web interface without requiring the installation of the cookiecutter tool on the client side. The platform features a GitHub repository to collect metadata about templates, a python-based backend, and a javascript Web GUI with the authentication via EGI Check-In. From data preprocessing to model evaluation, this session covers the most critical steps in the process of module development, empowering participants to achieve the desired reproducibility and reusability in their projects.

description: The structure of our Galaxy has been studied from ultraviolet (UV) star counts obtained with the Ultra-Violet Imaging Telescope (UVIT) on board the {\em AstroSat} satellite, in Far-UV (FUV) and Near-UV (NUV) bands. The F154W (BaF2) and N263M (NUVB4) filters were used in the FUV and NUV bands, respectively. The point sources are separated from the extra-galactic sources of UVIT observations using infrared (IR) color cut method. The observed UVIT star counts match well with the simulations obtained from the Besançon model of stellar population synthesis towards several Galactic directions. We also estimated the scale length and scale height of the thick disc and the scale height of the thin disc using the space density function and the exponential density law for the stars of intermediate Galactic latitudes. The scale length of the thick disc ranges from 3.11 to 5.40 kpc whereas the scale height ranges from 530$\pm$32 pc to 630$\pm$29 pc. The scale height of the thin disc comes out to be in the range of 230$\pm$20 pc to 330$\pm$11 pc.

description: We demonstrate an information hiding and retrieval scheme with the relative phases between states in a Rydberg wave packet acting as the bits of a data register. We use a terahertz half-cycle pulse (HCP) to transfer phase-encoded information from an optically accessible angular momentum manifold to another manifold which is not directly accessed by our laser pulses, effectively hiding the information from our optical interferometric measurement techniques. A subsequent HCP acting on these wave packets reintroduces the information back into the optically accessible data register manifold which can then be `read' out.

description: The objective of task 6.1 is to identify the functional and non-finctional requirements of the different stakeholders in the ReIReS consortium with regard to the resource discovery platform on religious history, which itself is the objective of Work Package 6. There exist already many digital resources and databases in this field. These are, however, still dispersed and the datasets are organized along various data models, which hinders the interoperability of all these resources related to religious studies. WP6 therefore aims to enhance the discoverability of data, regardless of location, metadata models, classifications and language while also improving visibility for public and commercial database providers.
 The first task and deliverable in this work package relates to the first steps generally taken in the creation of a data repository and discovery system: requirements analysis and use case models. The requirements analysis involves collecting input from the relevant data providers and researchers from the partner organizations regarding the needs and conditions that the unified data repository and discovery system must meet. User stories, the first step in collecting input, represent requirements told from the perspective of potential users to show the needs of future users. This helps to identify potential requirements the proposed platform needs to adhere to for it to become an instrument for resource discovery and linking for religious studies.
 A survey pertaining to the datasets already managed by the ReIReS partner institutions was also sent out to develop an overview of their potential interoperability on technical and metadata level. This is partly preparation for Task 6.2. (Metadata & ontology modeling), but in 6.1. serves to motivate the selection of datasets to be included in a pilot project of the unified repository and discovery system to be built on and to build on the requirements overview and use case models.

description: Cold inelastic collisions of atoms or molecules are analyzed using very general arguments. In free space, the deactivation rate can be enhanced or suppressed together with the scattering length of the corresponding elastic collision via a Feshbach resonance, and by interference of deactivation of the closed and open channels. In reduced dimensional geometries, the deactivation rate decreases with decreasing collision energy and does not increase with resonant elastic scattering length. This has broad implications; e.g., stabilization of molecules in a strongly confining two-dimensional optical lattice, since collisional decay of the highly vibrationally excited states due to inelastic collisions is suppressed. The relation of our results with those based on the Lieb-Liniger model are addressed.

School-house : additions and renovations to White Calf Collegiate, Lebret, Saskatchewan

Publisher: name: University of British Columbia
Year: 2009

description: White Calf Collegiate is a former residential school in Lebret, Saskatchewan that offers junior and secondary academic programs and accommodation for 220 students of First Nations ancestry. The thesis explores the possibility of interventions that resist the normalizing structures imposed by the architecture of the institution while using them to its' advantage. The thesis project accepts the former residential school as the ground on which a new architecture is inscribed Fundamental to the thesis is a belief that minor cultures best resist marginalization, not by operating in strict opposition to, but upon and within the major culture. The existing institution relies on a hierarchical and rational separation of spaces. These spaces are inflected inwards, clearly distinguishing the occupants relationships to one another, and their relationship to the surrounding landscape and to the greater community. A number of reorientations - physical and programmatic - are proposed. These reorientations where developed in relation to the physical site and ideas of movement through the landscape. As well, they acknowledge traditional relationships between edge and centre that are evident in Cree ceremonies and encampments. Significantly the domestic and heterotropic nature of the program is accented. The effect of these reorientations is to reestablish a relationship of the building to its' immediate site, and the social relationship of the students to one another and to the greater community. Fundamentally, there is a turning of what were once boundaries and limits, into in between spaces and edges. Porch spaces mediate between inside and outside, and between private and public domains. The central corridors are replaced by inhabitable halls linking living rooms which in turn open onto verandas. The envelope boundaries that once clearly established an inside and an outside become permeable membranes linking the building to its additions. The existing institution is both literally and figuratively undermined but only to the extent that it can be reclaimed. Its general order remains visible but no longer dominates.

description: A medium- and high-resolution spectroscopic survey of helium-rich hot subdwarfs is being carried out using the Southern African Large Telescope (SALT). Objectives include the discovery of exotic hot subdwarfs and of sequences connecting chemically-peculiar subdwarfs of different types. The first phase consists of medium-resolution spectroscopy of over 100 stars selected from low-resolution surveys. This paper describes the selection criteria, and the observing, classification and analysis methods. It presents 107 spectral classifications on the MK-like Drilling system and 106 coarse analyses ($T_{\rm eff}, \log g, \log y$) based on a hybrid grid of zero-metal non-LTE and line-blanketed LTE model atmospheres. For 75 stars, atmospheric parameters have been derived for the first time. The sample may be divided into 6 distinct groups including the classical `helium-rich' sdO stars with spectral types (Sp) sdO6.5 - sdB1 (74) comprising carbon-rich (35) and carbon-weak (39) stars, very hot He-sdO's with Sp $\lesssim$ sdO6 (13), extreme helium stars with luminosity class $\lesssim 5$ (5), intermediate helium-rich subdwarfs with helium class 25 -- 35 (8), and intermediate helium-rich subdwarfs with helium class $10 - 25$ (6). The last covers a narrow spectral range (sdB0 -- sdB1) including two known and four candidate heavy-metal subdwarfs. Within other groups are several stars of individual interest, including an extremely metal-poor helium star, candidate double-helium subdwarf binaries, and a candidate low-gravity He-sdO star.

description: Magnetic fields are ubiquitous in galaxy clusters, yet their radial profile, power spectrum, and connection to host cluster properties are poorly known. Merging galaxy clusters hosting diffuse polarized emission in the form of radio relics offer a unique possibility to study the magnetic fields in these complex systems. In this paper, we investigate the intra-cluster magnetic field in Abell 2345. This cluster hosts two radio relics that we detected in polarization with 1-2 GHz JVLA observations. X-ray XMM-Newton images show a very disturbed morphology. We derived the Rotation Measure (RM) of five polarized sources within $\sim$ 1 Mpc from the cluster center applying the RM synthesis. Both, the average RM and the RM dispersion radial profiles probe the presence of intra-cluster magnetic fields. Using the thermal electron density profile derived from X-ray analysis and simulating a 3D magnetic field with fluctuations following a power spectrum derived from magneto-hydrodynamical cosmological simulations, we build mock RM images of the cluster. We constrained the magnetic field profile in the eastern radio relic sector by comparing simulated and observed RM images. We find that, within the framework of our model, the data require a magnetic field scaling with thermal electron density as $B(r)\propto n_e(r)$. The best model has a central magnetic field (within a 200 kpc radius) of $2.8\pm0.1$ $μ$G. The average magnetic field at the position of the eastern relic is $\sim$0.3 $μ$G, a factor 2.7 lower than the equipartition estimate.

'Slow' and Fast Rotators among Hypervelocity Stars

description: We measure the projected rotational velocities of the late B-type hypervelocity stars HVS7 and HVS8 from high resolution spectroscopy to be 60 +/- 17 km/s and 260 +/- 70 km/s. The 'slow' rotation of HVS7 is in principle consistent with having originated in a binary system, assuming a high inclination angle of the stellar rotation axis. However, the fast rotation of HVS8 is more typical of single B-type stars. HVS8 could have therefore been ejected by a mechanism other than that proposed by Hills. We also estimate the effective temperatures and surface gravities for HVS7 and HVS8 and obtain an additional measurement of their radial velocities. We find evidence in support of a blue horizontal branch nature for HVS7, and a main sequence nature for HVS8.

Coherence as a key ingredient to learn effective communication strategies
Creators: name: Khalid, Baber
Publisher: name: No Publisher Supplied
Year: 2023

description: Coherence is a very important aspect of communication and helps keep track of the ongoing discussion. It gives structure to discourse and can be categorized through a set of qualitative coherence relations [Hobbs, 1979]. Human interlocutors collaborate with each other to engage in coherent communication and utilize a wide range of communication strategies, e.g., clarifications and corrections, to resolve any ambiguities in the context and achieve shared objectives [Clark and Wilkes-Gibbs, 1986]. Conversational models, based on MDP or end-to-end neural networks, assume that coherence can be estimated implicitly from the conversational data. In this work, we present a dialogue architecture which utilizes a coherence-aware state representation to learn communication in referential communication task. We show it is able to learn effective and flexible communication strategies which improve the task success rate. We also show that our coherence based state tracking mechanisms allow us to build simulation environments which can be used to empirically analyze different communication aspects such as clarifications. This enables us to identify the usefulness of techniques like reinforcement learning (RL) and identify cases where such techniques are most useful. Lastly, we present experiments which show how explicit use of coherence signals can help in building effective evaluation models.
Bulk versus Brane Emissivities of Photon Fields: For the case of Higher-Dimensional Schwarzschild Phase

description: The emission spectra for the spin-1 photon fields are computed when the spacetime is a $(4+n)$-dimensional Schwarzschild phase. For the case of the bulk emission we compute the spectra for the vector mode and scalar mode separately. Although the emissivities for the scalar mode is larger than those for the vector mode when $n$ is small, the emissivities for the vector mode photon become dominant rapidly with increasing $n$. For the case of the brane emission the emission spectra are numerically computed by making use of the complex potential method. Comparision of the total bulk emissivities with total brane emissivities indicates that the effect of the field spin makes the bulk emission to be rapidly dominant with increasing $n$. However, the bulk-to-brane relative emissivity per degree of freedom always remains smaller than unity. The importance for the spin-2 graviton emission problem is discussed.

Elastic positivity vs extremal positivity bounds in SMEFT: a case study in transversal electroweak gauge-boson scatterings

description: The positivity bounds, derived from the axiomatic principles of quantum field theory (QFT), constrain the signs of Wilson coefficients and their linear combinations in the Standard Model Effective Field Theory (SMEFT). The precise determination of these bounds, however, can become increasingly difficult as more and more SM modes and operators are taken into account. We study two approaches that aim at obtaining the full set of bounds for a given set of SM fields: 1) the traditional elastic positivity approach, which exploits the elastic scattering amplitudes of states with arbitrarily superposed helicities as well as other quantum numbers, and 2) the newly proposed extremal positivity approach, which constructs the allowed coefficient space directly by using the extremal representation of convex cones. Considering the electroweak gauge-bosons as an example, we demonstrate how the best analytical and numerical positivity bounds can be obtained in several ways. We further compare the constraining power and the efficiency of various approaches, as well as their applicability to more complex problems. While the new extremal approach is more constraining by construction, we also find that it is analytically easier to use, numerically much faster than the elastic approach, and much more applicable when more SM particle states and operators are taken into account. As a byproduct, we provide the best positivity bounds on the transversal quartic-gauge-boson couplings, required by the axiomatic principles of QFT, and show that they exclude $\approx 99.3\%$ of the parameter space currently being searched at the LHC.

description: We calculate the spectrum of fluctuations of a probe Dk-brane in the background of N Dp-branes, for k=p,p+2,p+4 and p< 5. The result corresponds to the mesonic spectrum of a (p+1)-dimensional super-Yang-Mills (SYM) theory coupled to `dynamical quarks', i.e., fields in the fundamental representation -- the latter are confined to a defect for k=p and p+2. We find a universal behaviour where the spectrum is discrete and the mesons are deeply bound. The mass gap and spectrum are set by the scale M ~ m_q/g_{eff}(m_q), where m_q is the mass of the fundamental fields and g_{eff}(m_q) is the effective coupling evaluated at the quark mass, i.e. g_{eff}^2(m_q)=g_{ym}^2 N m_q^{p-3}. We consider the evolution of the meson spectra into the far infrared of three-dimensional SYM, where the gravity dual lifts to M-theory. We also argue that the mass scale appearing in the meson spectra is dictated by holography.

description: Emerging artificial enzymes with reprogrammed and augmented catalytic activity and substrate selectivity have long been pursued with sustained efforts. The majority of current candidates rely on noble metals or transition metal oxides with rather poor catalytic activity compared with natural molecules. To tackle this limitation, we strategically designed a novel artificial enzyme based on a structurally well-defined Au25 cluster, namely clusterzyme, which is endowed with intrinsic high catalytic activity and selectivity driven by single-atom substitutions with modulated bond lengths. The 3-mercaptopropionic acid (MPA)-stabilized Au24Cu1 and Au24Cd1 clusterzymes exhibit 137 and 160 times higher antioxidant capacities than the natural trolox, respectively. Meanwhile, the clusterzymes each demonstrate preferential enzyme-mimicking catalytic activities with compelling selectivity: Au25 exhibits superior glutathione peroxidase-like (GPx-like) activity; Au24Cu1 shows a distinct advantage towards catalase-like (CAT-like) activity by its Cu single active site; Au24Cd1 preferably acts as a superoxide dismutase-like (SOD-like) enzyme via the Cd single active site. This unique diversified catalytic landscape manifests distinctive reactions against inflammation in brain. Au24Cu1 behaves as an endogenous multi-enzyme mimic that directly decreases peroxide in injured brain via catalytic reactions, while Au24Cd1, catalyzes superoxide and nitrogenous signal molecules by preference, and significantly decreases inflammation factors such as IL-1\b{eta}, IL-6, and TNFα, indicative of an important role in mitigating neuroinflammation.

description: We examine the AdS/CFT correspondence through a manifestly 5D supersymmetric formalism, corresponding to a 4D N=1 supersymmetric CFT. We find that the dimensions of scalar and fermionic component operators are simply related, and that there is a smooth transition of scalar operator dimensions through the value d_s = 2. By using this formalism, we also show that the formula used in the string literature for the dimension of fermion operators is incomplete.

description: We describe a cavity QED analogue for the coupling system of a spin and a nanomechanical resonator with a magnetic tip. For the quantized nanomechanical resonator, a spin-boson model for this coupling system can refer to a Jaynes-Cummings(JC) or an anti-JC model. These observations predict some quantum optical phenomena, such as squeezing and "collapse-revival" in the single oscillation mode of the nanomechanical resonator when it is initially prepared in the quasi-classical state. By modulating the phase of RF magnetic field one can switch the system between the JC and anti-JC model, which provides a potential protocol for the detection of the single spin. A damping mechanism is also analyzed.

description: The DArk Matter Particle Explorer (DAMPE) is a space-borne high energy cosmic-ray and $γ$-ray detector which operates smoothly since the launch on December 17, 2015. The bismuth germanium oxide (BGO) calorimeter is one of the key sub-detectors of DAMPE used for energy measurement and electron proton identification. For events with total energy deposit higher than decades of TeV, the readouts of PMTs coupled on the BGO crystals would become saturated, which results in an underestimation of the energy measurement. Based on detailed simulations, we develop a correction method for the saturation effect according to the shower development topologies and energies measured by neighbouring BGO crystals. The verification with simulated and on-orbit events shows that this method can well reconstruct the energy deposit in the saturated BGO crystal.

description: We show that the ratio of molecular to atomic gas in galaxies is determined by hydrostatic pressure and that the relation between the two is nearly linear. The pressure relation is shown to be good over three orders of magnitude for 14 galaxies including dwarfs, HI-rich, and H_2-rich galaxies as well as the Milky Way. The sample spans a factor of five in mean metallicity. The rms scatter of individual points of the relation is only about a factor of two for all the galaxies, though some show much more scatter than others. Using these results, we propose a modified star formation prescription based on pressure determining the degree to which the ISM is molecular. The formulation is different in high and low pressure regimes defined by whether the gas is primarily atomic or primarily molecular. This formulation can be implemented in simulations and provides a more appropriate treatment of the outer regions of spiral galaxies and molecule-poor systems such as dwarf irregulars and damped Lyman-alpha systems.

description: Generation of spin imbalance in nonmagnetic semiconductors is crucial for the functioning of many spintronic devices. An attractive design of spin injectors into semiconductors is based on a spin pumping from a precessing ferromagnet, typically excited by a microwave magnetic field leading to a high power consumption of the device. Here we describe theoretically a spin injector with greatly reduced energy losses, in which the magnetic dynamics is excited by an elastic wave injected into a ferromagnet-semiconductor heterostructure. To demonstrate the efficient functioning of such an injector, we perform micromagnetoelastic simulations of the coupled elastic and magnetic dynamics in Ni films and Ni/GaAs bilayers. For thick Ni films, it is shown that a monochromatic acoustic wave generates a spin wave with the same frequency and wavelength, which propagates over distances of several micrometers at the excitation frequencies close to the frequency of ferromagnetic resonance. The simulations of Ni/GaAs bilayers with Ni thicknesses comparable to the wavelength of the injected acoustic wave demonstrate the development of a steady-state magnetization precession at the Ni/GaAs interface. The amplitude of such a precession has a maximum at Ni thickness amounting to three quarters of the wavelength of the elastic wave, which is explained by an analytical model. Using simulation data obtained for the magnetization precession at the Ni/GaAs interface, we evaluate the spin current pumped into GaAs and calculate the spin accumulation in it by solving the spin diffusion equation. Then the electrical signals resulting from the spin flow and the inverse spin Hall effect are determined via the numerical solution of the Laplace's equation. It is shown that amplitudes of these ac signals are large enough for experimental measurement, which indicates an efficient acoustically driven spin pumping into GaAs.

title: Process Modeling of Composites for Automated Fiber Placement

description: Fiber-reinforced composites are available in various material systems, each requiring specific manufacturing techniques to exploit their unique properties fully. Systems such as woven fabrics and preimpregnated fibers employ distinctive methods to harness these properties effectively. For instance, non-crimp fabrics (NCF) use high-pressure resin transfer molding and prepregs, like IM7-8552, use manufacturing method called automated fiber placement (AFP). However, these manufacturing processes often introduce deposition features that can evolve into defects. Their occurrence and impact on morphology must be predicted using experimentally informed finite element models. The research began with compaction experiments on NCF fabric, leading to the development of a constitutive equation for an FEA model that simulated the evolution of fiber volume fraction and wrinkling between the woven fabric layers. The model highlighted the strain-rate dependence on fiber volume fraction distribution across NCF layers. The study then focused on the deposition of a prepreg tow on a composite substrate, modeled using a visco-hyperelastic constitutive equation with an anisotropic tensorial viscosity. This was coupled with a thermo-rheological model to predict heat transfer and resin development within the composite layers. Experiments with increasing substrate layers were conducted, with the spreading of the tow recorded in both experimental trials and numerical models. The substrate layers influenced the compaction and temperature gradient, affecting the substrate's viscous properties. After deposition, the visco-hyperelastic model was validated during early curing phases by creating and measuring unidirectional composite coupons, comparing this data to similar models. A laminate with a single fiber tow gap was also studied, revealing discrepancies in predicting resin rich region volumes. Incorporating resin bleed-out into the model improved accuracy by accounting for fiber volume fraction evolution and internal pressure in the fiber tow gap, providing structural support to the sinking plies. The addition of the resin bleed out results in a more accurate model prediction. The research culminates in attempting to predict the morphology of a laminate with multiple fiber tow gaps. Although the previous concepts were applied, they did not accurately predict the laminate's morphology, indicating potential for further research and the development of new concepts to simulate the composite manufacturing process accurately.

description: We have performed time-resolved spectroscopy on InAs quantum dot ensembles in photonic crystal membranes. The influence of the photonic crystal is investigated by varying the lattice constant systematically. We observe a strong slow down of the quantum dots' spontaneous emission rates as the two-dimensional bandgap is tuned through their emission frequencies. The measured band edges are in full agreement with theoretical predictions. We characterize the multi-exponential decay curves by their mean decay time and find enhancement of the spontaneous emission at the bandgap edges and strong inhibition inside the bandgap in good agreement with local density of states calculations.

The effect of rifampin on isoniazid-induced hepatotoxicity in rabbits

description: The objective of this study was to examine the effect of rifampin pretreatment on isoniazid-induced hepatotoxicity. For more than 25 years, it has been suggested that the concomitant administration of rifampin with isoniazid potentiates the hepatotoxicity induced by isoniazid. However, evidence to support this suggestion has been non-conclusive. Isoniazid and rifampin are still the two most commonly used drugs in the prophylaxis and treatment of tuberculosis. The relatively high incidence of tuberculosis throughout the world has not diminished and with more than 30 million deaths in this decade, tuberculosis is still the major killer among all single pathogens. Isoniazid is associated with potentially fatal liver damage in 1 - 2% of individuals exposed. However, the mechanism of isoniazid-induced hepatotoxicity remains largely unknown at the present time. Our laboratory has recently established a reliable model of isoniazid-induced hepatotoxicity in rabbits with features similar to those seen in humans. The dosing regimen in this study consisted of seven days rifampin pretreatment (50 mg/kg/day) followed by concomitant rifampin and isoniazid (each day consisting of an initial dose of 50 mg/kg followed by 3 x 35 mg/kg doses) administration for two days. Controls for each of these drugs were also included in the study design. The aim of the present study was to determine the effect of rifampin on the degree of isoniazid-induced hepatotoxicity, as well as to increase our understanding of the mechanism of isoniazid-induced hepatotoxicity. The following are the major findings in this thesis. Using the aforementioned protocol, rifampin significantly protected rabbits from isoniazid-induced hepatic necrosis. However, rifampin had no significant effect on plasma levels of hydrazine at 12 or 32 hours of isoniazid dosing in rabbits receiving rifampin plus isoniazid. Rifampin treatment alone significantly decreased cytochrome P-450 (CYP) 2E1 and significantly increased cytochrome P-450 reductase activities. The protective effect of rifampin in INH-induced hepatotoxicity could be due to its effect on CYP2E1 or reductase activities or another effect of rifampin not measured in this study. In conclusion, the protective effect of rifampin on isoniazid-induced hepatic necrosis observed in this study is concordant with the results of a double-blind placebo-controlled trial in humans, adding to the support for the usefulness of this rabbit model.

description: The Auto Incident Recording System (AIRS) is a sound-actuated video recording system. It automatically records potential incidents when activated by sound (horns, clashing metal, squealing tires, etc.). The purpose is to detect patterns of crashes at intersections for use in implementing relevant improvements. Videos of incidents and near-incidents were obtained after AIRS was placed in service at an intersection in Louisville, Kentucky on July 22, 2001. Crash reports were obtained from January 1998 through September, 2004 to; a) compare to the available data from AIRS videos, and b) compare the crashes before and after various improvements were made. A traffic conflict study was made at the intersection and the the traffic conflictdata was compared to results obtained from AIRS and to the crash summary.

description: The terrestrial magnetopause is the boundary that shields the Earth's magnetosphere on one side from the shocked solar wind and its embedded interplanetary magnetic field on the other side. In this paper, we show observations from two of the Time History of Events and Macroscales Interactions during Substorms (THEMIS) satellites, comparing dayside magnetopause crossings with flank crossings near the terminator. Macroscopic properties such as current sheet thickness, motion, and current density are examined for a large number of magnetopause crossings. The results show that the flank magnetopause is typically thicker than the dayside magnetopause and has a lower current density. Consistent with earlier results from Cluster observations, we also find a persistent dawn-dusk asymmetry with a thicker and more dynamic magnetopause at dawn than at dusk.
