description: Turbidity currents are turbulent particle suspensions that are the primary mechanism for transporting terrestrial sediments to the deep marine, and generate some of the largest depositional features on Earth. However the fluid-particle interactions that sustain these currents are poorly understood, principally due to the technical challenges posed by obtaining accurate velocity and density measurements, which are critical for describing flow behavior and depositional characteristics. Numerous studies have bypassed these issues by using saline density currents, but this negates the ability to link flow processes with depositional features, and it is unclear whether their density structures are representative of particle gravity flows. Consequently, numerous questions remain over the flow conditions that build up a significant part of the deep-marine geologic record. In this thesis I reports on the flow processes and depositional features of sediment-gravity currents across a broad range of particle sizes and concentrations. The technical challenges of obtaining reliable density data are overcome by running the experimental flows through a medical grade computed tomography (CT) scanner, and pair this data with three-dimensional velocity measurements using an ultrasonic Doppler velocity profiler (UDVP-3D) to get one of the first glimpses of the internal structure of turbidity currents. Unlike previous studies where flow processes are described in terms of the velocity field, this thesis demonstrates that fluid-particle interactions are controlled by momentum characteristics, and that the velocity field is determined largely by the current’s density structure. Moreover, the density structure also exerts a first order control on the morphology of their deposits.

Digital image watermarking for ownership verification
Creators: name: Guo, Huiping
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2003
Subjects: subject: Computer Science.

description: The development of the Internet has greatly contributed to the expanded use of digital media, for example, images, audio, video, VRML objects. These media can be duplicated unlimitedly without any quality loss and can also be easily distributed and tempered. This presents problems of digital media security, such as copyright protection and authentication, which creates a pressing need for digital media protection schemes. A new emerging technology, digital watermarking, protects digital media by embedding a robust signal directly into the media, thus providing a promising way to protect the digital media from illicit copying and manipulation. In this thesis, we mainly consider digital image watermarking for ownership verification. Though lots of such schemes have been proposed in literature, there are still some problems that have not been addressed or have not been adequately addressed such as how to detect a watermark progressively while at the same time be robust to geometrical transformations, how to embed a watermark in the fractal domain and how to embed a watermark into an object in an image instead of into the whole image. Several new watermarking algorithms are proposed here to address these problems respectively and experiments show satisfactory results. The next problem that has been ignored by the watermarking community is the joint ownership verification. If an image is created collaboratively by multiple owners, all current watermarking schemes will fail to protect the image from potential dishonest owners, since they are only designed to protect an image from dishonest users. To address this problem, a novel framework of the watermarking system that makes use of a secret sharing scheme is proposed. Based on this framework, several new watermarking algorithms are proposed where the secret watermark embedding key is split into shares and each owner holds one share. Multiple watermarks contributed by each owner are embedded into spectrum domain of the image and multiple thresholds are set so that the watermark can verify joint ownership as well as partial ownership. To the best knowledge of the author, the problem of joint ownership has not been addressed so far and the watermarking schemes proposed are the first ones to address them.

description: SCUBA-2 is an innovative 10,000 pixel submillimeter camera due to be delivered to the James Clerk Maxwell Telescope in late 2006. The camera is expected to revolutionize submillimeter astronomy in terms of the ability to carry out wide-field surveys to unprecedented depths addressing key questions relating to the origins of galaxies, stars and planets. This paper presents an update on the project with particular emphasis on the laboratory commissioning of the instrument. The assembly and integration will be described as well as the measured thermal performance of the instrument. A summary of the performance results will be presented from the TES bolometer arrays, which come complete with in-focal plane SQUID amplifiers and multiplexed readouts, and are cooled to 100mK by a liquid cryogen-free dilution refrigerator. Considerable emphasis has also been placed on the operating modes of the instrument and the "common-user" aspect of the user interface and data reduction pipeline. These areas will also be described in the paper. Copyright 2006 Society of Photo-Optical Instrumentation Engineers. One print or electronic copy may be made for personal use only.

description: Follicle stimulating hormone (FSH) is an important survival factor in the ovarian follicular development. Inhibitor of apoptosis proteins (IAPs) is a family of intracellular anti-apoptosic proteins. X-linked IAP (XIAP) has been shown to be involved in multiple biological activities (e.g. inhibition of caspase activities, promotion of ubiquitin-proteasome-mediated protein degradation, regulation of cell signaling pathways). The present thesis research project examines: (1) the role and gonadotropic regulation of XIAP expression in rat granulosa cells during ovarian follicular development and atresia; (2) the possible involvement of intra-ovarian factors such as transforming growth factor alpha (TGFalpha) in the FSH-induced XIAP expression and follicular development; and (3) the signal pathways involved in the gonadotropic up-regulation of XIAP during follicular development in vitro. A follicle culture system coupled to an adenoviral gene manipulation procedure has been established. FSH significantly increased follicular growth as evident by increases in follicular size, cell number and DNA contents in vitro. While cultured pre-antral or early-antral follicles showed a low XIAP content and evidence of apoptosis in the absence of FSH, gonadotropin addition increased XIAP content and suppressed apoptosis. At low FSH concentration, adenoviral XIAP sense cDNA expression increased follicular cell XIAP and DNA contents, reduced apoptosis, and enhanced follicular growth, while XIAP antisense elicited opposite responses. FSH-induced XIAP up-regulation appeared mediated, in part, by the secretion and action of follicular TGFalpha. In cultured rat follicles, FSH-stimulated estradiol production, TGFalpha secretion, XIAP expression and follicular growth were suppressed by intra-follicular injection of a neutralizing anti-TGFalpha antibody or addition of the estradiol antagonist ICI 182780 to the culture media. These results support my hypothesis that the FSH induces follicular growth by stimulating granulosa cell proliferation via theca TGFalpha secretion and action in response to increased granulosa cell estradiol synthesis. Since the promoter region of XIAP gene has nuclear kappa B (NFkappaB) binding site, it is possible that the transcription of XIAP is mediated via NFkappaB activation. FSH increased rat granulosa cell XIAP mRNA abundance and protein content. While the gonadotropin induced granulosa cell NFkappaB translocation from cytoplasm to nucleus and increased NFkappaB-DNA binding activity, pretreatment with an NFkappaB translocation inhibitor suppressed FSH-stimulated XIAP expression.

description: Gulf War syndrome is a chronic multi-symptom illness that has affected about a quarter of the deployed veterans of the 1991 Gulf War. Exposure to prolonged low-level organophosphate insecticides and other toxic chemicals is now thought to be responsible. Chlorpyrifos was one commonly used insecticide. The metabolite of chlorpyrifos, chlorpyrifos oxon, is a potent irreversible inhibitor of acetylcholinesterase, much like the nerve agent Sarin. To date, the target brain region(s) most susceptible to the neuroactive effects of chlorpyrifos oxon have yet to be identified. To address this we tested ability of chlorpyrifos oxon to influence neuronal excitability and induce lasting changes in the locus coeruleus, a brain region implicated in anxiety, substance use, attention and emotional response to stress. Here we used an ex vivo rodent model to identify a dramatic effect of chlorpyrifos oxon on locus coeruleus noradrenergic neuronal activity. Prolonged exposure to chlorpyrifos oxon caused acute inhibition and a lasting rebound excitatory state expressed after days of exposure and subsequent withdrawal. Our findings indicate that the locus coeruleus is a brain region vulnerable to chlorpyrifos oxon-induced neuroplastic changes possibly leading to the neurological symptoms affecting veterans of the Gulf War.

description: This article uses a combination of documentary and physical evidence to explore variations in the historic housing stock of the county. Particular emphasis is placed on the use of hearth tax records as a meter of these variations. The author suggests that the hearth tax reveals distinct variations in the vernacular housing stock of seventeenth-century Norfolk, and that the roots of these variation are to be found not only in the emergence of distinctive farming economies and social structures based on soil regions, but also in the emergence of divergent building traditions.

description: We present the results of characterization measurements on a 1280 pixel superconducting bolometer array designed for operation at wavelengths around 450 μm. The array is a prototype for the sub-arrays which will form the focal plane for the SCUBA-2 sub-mm camera, being built for the James Clerk Maxwell Telescope (JCMT) in Hawaii. With over 10 000 pixels in total, it will provide a huge improvement in both sensitivity and mapping speed over existing instruments. The array consists of molybdenum-copper bi-layer TES (transition edge sensor) pixels, bonded to a multiplexer. The detectors operate at a temperature of approximately 175 mK, and require a heat sink at a temperature of approximately 60 mK. In contrast to previous TES arrays, the multiplexing elements are located beneath each pixel (an "in-focal plane" configuration). We present the results of electrical and optical measurements, and show that the optical NEP (noise equivalent power) is less than 1.4 × 10-16 W Hz-0.5 and thus within the goal of 1.5 × 10-16 W Hz-0.5.

Vision-based localization, map building and obstacle reconstruction in ground plane environments
Creators: name: Hajjdiab, Hassan
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2004
Subjects: subject: Artificial Intelligence.
subject: Computer Science.

description: The work described in this thesis develops the theory of 3D obstacle reconstruction and map building problems in the context of a robot, or a team of robots, equipped with one camera mounted on board. The study is composed of many problems representing the different phases of actions taken by the robot. This thesis first studies the problem of image matching for wide baseline images taken by moving robots. The ground plane is detected and the inter-image homography induced by the ground plane is calculated. A novel technique for ground plane matching is introduced using the overhead view transformation. The thesis then studies the simultaneous localization and map building (SLAM) problem for a team of robots collaborating in the same work site. A vision-based technique is introduced in this thesis to solve the SLAM problem. The third problem studied in this thesis is the 3D obstacle reconstruction of the obstacles lying on the ground surface. In this thesis a Geometric/Variational level set method is proposed to reconstruct the obstacles detected by the robots.
SPIDER: a new balloon-borne experiment to measure CMB polarization on large angular scales.
Creators: name: Halpern, Mark
Publisher: name: Society of Photo-Optical Instrumentation Engineers (SPIE)
Year: 2011

description: We describe SPIDER, a novel balloon-borne experiment designed to measure the polarization of the Cosmic Microwave Background (CMB) on large angular scales. The primary goal of SPIDER is to detect the faint signature of inflationary gravitational waves in the CMB polarization. The payload consists of six telescopes, each operating in a single frequency band and cooled to 4 K by a common LN/LHe cryostat. The primary optic for each telescope is a 25 cm diameter lens cooled to 4 K. Each telescope feeds an array of antenna coupled, polarization sensitive sub-Kelvin bolometers that covers a 20 degree diameter FOV with diffraction limited resolution. The six focal planes span 70 to 300 GHz in a manner optimized to separate polarized galactic emission from CMB polarization, and together contain over 2300 detectors. Polarization modulation is achieved by rotating a cryogenic half-wave plate in front of the primary optic of each telescope. The cryogenic system is designed for 30 days of operation. Observations will be conducted during the night portions of a mid-latitude, long duration balloon flight which will circumnavigate the globe from Australia. By spinning the payload at 1 rpm with the six telescopes fixed in elevation, SPIDER will map approximately half of the sky at each frequency on each night of the flight.

Focus errors from tracking sodium layer altitude variations with laser guide star adaptive optics for the Thirty Meter Telescope.
Creators: name: Hickson, Paul
Publisher: name: Society of Photo-Optical Instrumentation Engineers (SPIE)
Year: 2011

description: Laser guide star (LGS) adaptive optics systems for extremely large telescopes must handle an important effect that is negligible for current generation telescopes. Wavefront errors, due to improperly focusing laser wavefront sensors (WFS) on the mesospheric sodium layer, are proportional to the square of the telescope diameter. The sodium layer, whose mean altitude is approximately 90 km, can move vertically at rates of up to a few metres per second; a few seconds lag in refocusing can substantially degrade delivered image quality (15 m of defocus can cause 120 nm residual wavefront error on a 30-m telescope.) As well, the range of temporal frequencies of sodium altitude focus, overlaps the temporal frequencies of focus caused by atmospheric turbulence. Only natural star wavefront sensors can disentangle this degeneracy. However, applying corrections with representative focus mechanisms having modest control bandwidths causes appreciable tracking errors. In principle, electronic offsets measured by natural guide star detectors could be rapidly applied to laser WFS measurements, but to provide useable sky coverage, integrating sufficient photons causes an unavoidable time delay, again resulting in potentially serious focus tracking errors. However, our analysis depends on extrapolating to temporal frequencies greater than 1 Hz from power spectra of sodium profile time series taken at 1-2 minute intervals. In principle, with a pulsed laser, (e.g. 3-µs pulses) and dynamic refocusing on a polar-coordinate CCD, this focus tracking error may be eliminated. This result is an additional benefit of dynamic refocusing beyond the commonly recognized amelioration of LGS WFS spot elongation. Copyright 2006 Society of Photo-Optical Instrumentation Engineers.

Introduction: Multidisciplinary Perspectives on Innovation in East Asia
Creators: name: Conlé, Marcus
Publisher: name: Asien
Year: 2021

description: Previous research on developments within East Asian societies has demonstrated that the “East Asian miracle,” and with it the region’s renewed ascent to being an economic, political, and cultural hub, is a lot more than just the story of labor surpluses, the diffusion of established knowledge, and imitation. Novelties that quickly come to mind range from Japanese production systems (e.g. Womack et al. 1990) and the more recently discussed Chinese manufacturing approaches (Berger 2013; Steinfeld and Beltoft 2014), to Japanese humanoid robotics, Korean online gaming, and various other pop cultural phenomena associated with “Cool Japan” and the “Korean Wave” (e.g. Storz 2008; Wagner 2009; Wi 2009). Developments and achievements like these raise expectations that the region will also originate thought-provoking and impactful responses to those societal challenges that are currently high on the agenda of decision makers around the world. Among the most pressing challenges faced are those that are identified, for instance, in the European Union’s “Horizon 2020,” which comprise, inter alia, food security, healthcare, the provision of “smart, green and integrated transport” — particularly in urban environments — and “secure, clean and efficient energy.” (Horizon 2020) In short, the manifold developments within the region are a valuable source of inspiration, knowledge, and reflection in two respects: for finding tools to address real-world problems and for pushing innovation research more generally. Tapping the full potential of the vast repertoire of regional experiences, initiatives, and solutions is, however, impossible to achieve without cross-disciplinary exchange and the provision of fora for bringing together different lines of research.

Dabei wurde der Ansatz des radialen Basisfunktionen Least Orthogonal Interpolant Verfahrens (RBF-LOI) und des radialen Basisfunktionen finite Differenzen Verfahrens (RBF-FD) in schwacher Form kombiniert. Es wurde dabei eine Methode hergeleitet, um die Oberfläche gitterfrei zu approximieren, was die approximative Auswertung von schwachen Formen von Differentialoperatoren auf Mannigfaltigkeiten erlaubt. Hierzu wird zuerst die nötige Theorie zu der Interpolation mit radialen Basisfunktionen, des RBF-FD-Verfahrens und der Differentialgeometrie erläutert. Darauf aufbauend wird das neue Verfahren vorgestellt und eine Fehleranalyse durchgeführt. Anschließend wird das Verfahren auf verschieden Poisson-Problemen mit inhomogenen Dirichlet-Randbedingungen auf Mannigfaltigkeiten angewandt, um das Fehlerverhalten in Anwendungen zu beurteilen.

Catégorisation acoustique des voyelles moyennes antérieures arrondies en français laurentien

Subjects: subject: Language, Linguistics.

description: L'objectif de cette thèse est d'offrir une contribution à la catégorisation acoustique des voyelles moyennes antérieures arrondies (VMAA) en français laurentien (FL). Pour ce faire, des analyses statistiques ont été exécutées sur un ensemble de sept VMAA évoluant en syllabe ouverte: quatre VMAA non finales ([o], [oe] , schwa stable et schwa instable) et trois VMAA finales (la voyelle de l'enclitique --le, la lettre  et la voyelle de la pause remplie (euh)). Les données proviennent de trois corpus de trente locuteurs de français laurentien. Les traitements statistiques consistent en une analyse spectrale des trois premiers formants (F1, F2, F3), une analyse de la corrélation entre la durée et le timbre de la voyelle et une analyse de la variabilité des voyelles. Les résultats ont montré que la catégorisation est possible pour la voyelle [o], qui s'éloigne du centre de l'espace vocalique autour duquel gravitent les autres VMAA. En outre, le comportement de la voyelle de la pause remplie suggère qu'elle n'est pas soumise aux contraintes temporelles qui affectent les autres voyelles à l'étude: d'une durée extraordinaire, elle se situe malgré tout au centre de l'espace vocalique, ce qui suggère qu'elle pourrait correspondre à une base articulatoire. Les cinq VMAA restantes forment un regroupement de voyelles au centre de l'espace vocalique du FL. Le chevauchement des aires de dispersion pour chacune des voyelles et la faible valeur de l'effet statistique sur F2 et F3 empêchent une catégorisation acoustique décisive, malgré les différences significatives révélées par les analyses formantiques. La position des voyelles sur le plan cartésien F2/F1 suggère qu'il existe une corrélation entre la durée de la voyelle et l'endroit ou elle fait surface: plus elle s'allonge, plus elle se déplace vers le bas sur l'axe vertical (F1). Je rends compte de ce comportement proposant l'existence d'une seule voyelle générique dont on observe le comportement dans cinq conditions temporelles différentes, de la voyelle courte à la voyelle très longue.

NFIRAOS: TMT narrow field near-infrared facility adaptive optics.
Creators: name: Hickson, Paul
Publisher: name: Society of Photo-Optical Instrumentation Engineers (SPIE)
Year: 2011

description: Although many of the instruments planned for the TMT (Thirty Meter Telescope) have their own closely-coupled adaptive optics systems, TMT will also have a facility Adaptive Optics (AO) system, NFIRAOS, feeding three instruments on the Nasmyth platform. This Narrow-Field Infrared Adaptive Optics System, employs conventional deformable mirrors with large diameters of about 300 mm. The requirements for NFIRAOS include 1.0-2.5 microns wavelength range, 30 arcsecond diameter science field of view (FOV), excellent sky coverage, and diffraction-limited atmospheric turbulence compensation (specified at 133 nm RMS including residual telescope and science instrument errors.) The reference design for NFIRAOS includes six sodium laser guide stars over a 70 arcsecond FOV, and multiple infrared tip/tilt sensors and a natural guide star focus sensor within instruments. Larger telescopes require greater deformable mirror (DM) stroke. Although initially NFIRAOS will correct a 10 arcsecond science field, it uses two deformable mirrors in series, partly to provide sufficient stroke for atmospheric correction over the 30 m telescope aperture, but mainly to improve sky coverage by sharpening near-IR natural guide stars over a 2 arcminute diameter "technical" field. The planned upgrade to full performance includes replacing the ground-conjugated DM with a higher actuator density, and using a deformable telescope secondary mirror as a "woofer." NFIRAOS feeds three live instruments: a near-Infrared integral field Imaging spectrograph, a near-infrared echelle spectrograph, and after upgrading NFIRAOS to full multi-conjugation, a wide field (30 arcsecond) infrared camera.

To the heart of the continent: Canada and the negotiation of the St Lawrence Seaway and Power Project, 1921--1954

description: The St. Lawrence Seaway and Power Project, built cooperatively between 1954 and 1959 by Canada and the United States, is the largest navigable inland waterway in the world and the largest borderlands project ever undertaken jointly by two countries. This thesis combines diplomatic, political, and environmental history to chart the course of domestic and international negotiations, particularly in the 1945-1954 period, that resulted in the bilateral 1954 agreement to build the seaway. The focus is on the Canadian federal government and to a lesser extent the U.S. federal government, as well as involved state and provincial governments and their public power utilities. These negotiations are extremely revealing in terms of the history of Canadian-American relations, and this thesis also examines issues connected to North American attitudes toward water resources, state-building, high modernism, and technology in the early Cold War period. After a number of failed attempts at a cooperative waterway, in the late 1940s the Liberal government of Louis St. Laurent began to explore the possibility of an all-Canadian seaway, and backed by widespread public support, had adopted this as policy by 1952. The drive for an all-Canadian seaway stemmed from various forms of nationalism which framed the St. Lawrence as an exclusively "Canadian" resource that was intimately tied to Canadian identity. However, the Truman administration and different American interests deemed a unilateral Canadian waterway to be an economic and national security threat to the United States, and delayed the requisite power licenses needed for Canada to undertake the transborder St. Lawrence project. Canada partly contributed to this situation by repeatedly making vague offers to leave the door open project. The Eisenhower administration also stalled Ottawa's efforts to "go it alone" until American participation was finally sanctioned by Congress in 1954 and the requisite licenses were granted. The St. Laurent government then reluctantly acquiesced to the American desire for a joint endeavour in order to maintain harmonious Canada-U.S. relations, although Canada did extract key concessions from Washington about the shape and placement of the project.

Lunar Liquid Mirror Telescope (LLMT) for deep-field infrared observations near the lunar pole.

Year: 2011

description: We have studied the feasibility and scientific potential of a 20 - 100 m aperture astronomical telescope at the lunar pole, with its primary mirror made of spinning liquid at less than 100K. Such a telescope, equipped with imaging and multiplexed spectroscopic instruments for a deep infrared survey, would be revolutionary in its power to study the distant universe, including the formation of the first stars and their assembly into galaxies. The LLMT could be used to follow up discoveries made with the 6 m James Webb Space Telescope, with more detailed images and spectroscopic studies, as well as to detect objects 100 times fainter, such as the first, high-red shift stars in the early universe. Our preliminary analysis based on SMART-1 AMIE images shows ridges and crater rims within 0.5° of the North Pole are illuminated for at least some sun angles during lunar winter. Locations near these points may prove to be ideal for the LLMT. Lunar dust deposited on the optics or in a thin atmosphere could be problematic. An in-situ site survey appears necessary to resolve the dust questions. Copyright 2006 Society of Photo-Optical Instrumentation Engineers.

Hamon: An Activity Recognition Framework for Health Monitoring Support in Home Environments
Creators: name: Alhamid, Mohammed
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Computer Science.

description: Nowadays, technology advances accelerate the quality and type of services provided for health care and especially for monitoring health conditions. Sensors have become more powerful to sense different physiological signs and have the ability to be worn on the human body using wireless communication modules. A variety of software tools have been developed to help in processing a variance list of vital signs by analyzing and visualizing data generated by multiple sensors. In this thesis, we introduced a Health signs and Activity recognition MONitoring framework (Hamon). Hamon, of German origin meaning a home protector, is designed to be an enabling prototype for health monitoring applications. Using off-the-shelf sensors, we implemented an activity detection framework for detecting five types of activity: falling, lying down, sitting, standing, and walking. The framework collects and analyzes sensory data in real-time, and provides different feedback to the users. In addition, it can generate alerts based on the detected events and store the data collected to a medical sever. Context information such as the weather condition, the type of activity, and physiological data collected such as the heart rate, is also integrated in the framework. A number of challenges have been addressed in this thesis including: the design and the implementation of the framework, the selection and the implementation of the activity recognition algorithm, and the classification method used for detection.
Adhesive Applied Roofing System Resistance Evaluation and its Quantification

Subjects: subject: Engineering, Civil.

description: Adhesive Applied Roofing System (AARS) is a new generation of built-up roof, gaining popularity in the North American low-slope roofing market. All components of AARS are integrated using adhesives. Wind flow creates suction over a low-slope roof, which exerts uplift forces on the roof system. The components of AARS are subjected to the combined action of tensile and shearing forces due to the dynamic wind uplift action. As part of a research project, to quantify the wind performance of AARS, three different test methods, namely, pullout (to simulate the tensile force), peel (to simulate the shear force), and wind uplift tests were developed by Current (2009), Wu (2008) and Murty (2010), respectively. Three test methods have been submitted to standard development organizations for industrial applications. The present study proposes a correlation among these three different test methods, namely, "Higher resistance in both peel and pullout tests will result in the same or higher wind uplift resistance". The present proposal is being verified through experimental study. For four different scenarios, two set of samples were constructed by varying only one component between the samples. For each sample, more than eight specimens were tested in all three test methods. Data from peel, pullout and wind uplift test methods were compared and it successfully verified the present hypothesis. It is concluded that the test results obtained from the small-scale pullout and peel experiments can be used to predict the effectiveness of full-scale system behaviour. This finding is very useful to assess the wind uplift performance of AARS that are already in service. It is also applicable to the situation where the component substitution for AARS is needed at the construction site. To help the industrial partners, a portable tester was designed such that it can be used for pullout and peel tests in the field. The design specifications of the portable tester were extracted from the requirements of the pullout and peel test methods based on the laboratory tests. The tester was manufactured by SAI Design Inc. First, the functionality of the portable tester was verified by testing the resistance of roofing fasteners. To further validate the portable tester, more than two hundred AARS specimens of different configurations were constructed and tested by using both the portable tester and Instron machine. The test results and observed failure modes were compared. The data confirmed that the portable tester is a useful and valid equipment in performing both the pullout and peel tests. The device can be used in the field for the evaluation of system response under wind action. Thus it will be useful in quantifying the impact of environmental conditions on the AARS specimens and to examine the effects of component substitutions.

description: Spontaneous clearance of hepatitis C (HCV) may provide protection against re-infection. In a large, community-based cohort study of 3,553 inner city residents (consisting mainly of injection drug users), we identified HCV-infected individuals in whom virologic clearance had occurred and compared the rate of re-infection in this group to that observed in previously uninfected members of the same cohort. We identified 926 HCV uninfected and 658 infected viremic subjects at baseline, with 152/658 (23.1%) spontaneously clearing viremia over a median follow-up of 5.2 years (IQR, 2.8-7.4). At baseline, individuals with HCV clearance were more likely to be HIV co-infected (P<0.001), engaged in frequent illicit drug use (P=0.004) and injection drug use (P<0.001). The occurrence of HCV infection was lower in individuals with previous infection (14/152, 9.2%) when compared to those without previous infection (172/926, 18.6%), with incidence rates of 1.8 (95% CI, 0.9-3.0 cases/100 person-years) and 8.1 cases/100 person-years (95% CI, 6.9-9.4 cases/100 person-years), respectively, after accounting for follow-up. In a logistic regression analysis, when previous HCV infection was assessed as a covariate with other potential confounding variables (age, sex, ethnicity, HIV infection, housing status and illicit and injection drug use), individuals with previous HCV infection and viral clearance were 4 times less likely to develop infection than those infected for the first time [adjusted odds ratio, 0.23; 95% CI, 0.10-0.51, P<0.001]. In conclusion, individuals with clearance of HCV infection may have a lower risk of acquiring HCV than individuals who have never been infected, despite ongoing exposure to HCV.

description: Traditionally, common processor augmentation solutions have involved the addition of coprocessors or the datapath integration of custom instructions within extensible processors as Instruction Set Extensions (ISE). Rarely is the hybrid option of using both techniques explored. Much research already exists concerning the mutually exclusive identification and selection of custom hardware blocks from hardware/software partitioning techniques. The question of how to best select and use this hardware within a user system where both coprocessors and datapath augmentations are possible and are mutually inclusive remains. Here a system with both types of these custom instructions is denoted as a hybrid SoC. In this work, both the coprocessor and internal datapath custom instruction design decisions are modeled within a design space exploration framework created to facilitate hybrid SoC development. We explore how to best select and integrate these instructions using available metrics and traditional combinatorial optimization techniques while packaging these ideas together into a complete toolchain framework. This framework is integrated into industry design flow tools in an attempt to achieve significant performance gains over existing methodologies.

description: Non-commutative diagrams, where X → Y → Z is allowed and X → Z → Y is not, may equally well apply to Malusian experiments with photons traversing polarizers, and to sequences of elementary chemical reactions. This is why non-commutative probabilistic, logical, and dynamical structures necessarily occur in chemical or biological dynamics. We discuss several explicit examples of such systems and propose an exactly solvable nonlinear toy model of a “brain–heart” system. The model involves non-Kolmogorovian probability calculus and soliton kinetic equations integrable by Darboux transformations.

description: Genus Aptesis Förster, 1850
 Aptesis Förster, 1850: 71. Type species: Ichneumon sudeticus Gravenhorst, 1815. Designated by Viereck (1914).
 Pezoporus Förster, 1869: 181. Type species: Ichneumon nigrocinctus Gravenhorst, 1815. Name preoccupied.
 Clypediodon Aubert, 1968: 7. Type species: Aptesis (Clypeodiodon) flavifaciator Aubert, 1968. Original designation.
 Diagnosis. Townes (1970) proposed diagnosis of this genus. We refer it with some additional data of character states of Japanese species below. Clypeus weakly to moderately convex in lateral view, its apex truncate or somewhat arcuate (Figs 1B, 2B, 3A, B). Median 0.2 and more of apical margin of clypeus sharp, narrowly reflexed (Figs 1B, 2B, 3A, B). Mandible with two teeth, its upper tooth as long as (Fig. 3B) or shorter than lower tooth. Apical half of flagellum not strongly flattened below, not strongly tapered to apex (Figs 1A, 2A, 3A). Basal flageller segments short and slender (Figs 1A, 2A, 3A), F2 shorter than 3.3 times as long as wide in lateral view. Propodeal spiracle not strongly elongate (Fig. 3E), at most 2.0 times as long as wide. Areolet pentagonal (Fig. 3C). Spiracle of T1 situated behind the mid-length (Fig. 3D). Postpetiole usually with a complete or incomplete dorsolateral longitudinal carina or ridge between its spiracle and apicolateral corner (Fig. 3D). T2 more or less polished (Figs 1A, F, 2A). Ovipositor straight, its upper valve without oblique or transverse teeth (Figs 1A, 3F).
 Distribution. Holarctic, Oriental and Afrotropical regions (Yu et al., 2012).
 Remarks. Eleven species of this genus were previously recorded from Eastern Palaearctic region (Yu et al., 2012; Li et al., 2013). Japanese fauna of this genus is still poorly studied. We recognized seven species of this genus from Japan. Three of them are described species, A. albibasalis (Uchida, 1930), A. albidipes (Walker, 1874) and A. opaca (Cushman, 1937). In this study, we describe a new species, Aptesis flavitrochanterus sp. nov., which was previously recorded as Aptesis sp. A by Taniwaki & Watanabe (2012). The remainders may be undescribed or unrecorded species.
Females of Japanese species of this genus can be distinguished by the following preliminary key. Identification of males difficult, thus identification of the new species should be compared with the following original description.

description: Considering transport or tendency of transport of physical entities from an initial to a final point,we come to a similar basis of understanding of various physical phenomena.The trajectory-behaviour of such transport represents the effect or field of influence.This way,we may explain cluster-formation in the universe,an expanding universe,etc.This may also lead to a similar basis for understanding the four non-contact forces of nature.Also,for different ranges of acceleration in the field formed in spacetime,we have different properties of matter interacting.This may explain the difference in ranges of the various forces.
