Coronaviruses in the Sea
Creators: name: Mordecai, Gideon

Publisher: name: Frontiers

description: Interest in coronaviruses because of the 2019 novel coronavirus (SARS-CoV-2) pandemic has generated concern about their occurrence and persistence in aquatic habitats. Coronaviruses are not quantitatively significant constituents of marine virioplankton. Members of the Nidovirales (to which human coronaviruses belong) infect marine mammals, teleosts and possibly invertebrates, and human coronaviruses may persist in marine plankton receiving wastewater effluent. However, virions likely experience significant particle and infectivity decay rates in surface seawater, similar to other enveloped RNA viruses.

description: Living organisms are made up of a multitude of individual cells that are surrounded by biomolecules and fluids. It is well known that cells are highly regulated by biochemical signals; however it is now becoming clear that cells are also influenced by the mechanical forces and mechanical properties of the local microenvironment. Extracellular forces causing cellular deformation can originate from many sources, such as fluid shear stresses arising from interstitial or blood flow, mechanical stretching during breathing or compression during muscle contraction. Cells are able to sense variations in the mechanical properties (elasticity) of their microenvironment by actively probing their surroundings by utilizing specialized proteins that are involved in sensing and transmitting mechanical information. The actin cytoskeleton and myosin-II motor proteins form a contractile (actomyosin) network inside the cell that is connected to the extracellular microenvironment through focal adhesion and integrin sites. The transmission of internal actomyosin strain to the microenvironment via focal adhesion sites generates mechanical traction forces. Importantly, cells generate traction forces in response to extracellular forces and also to actively probe the elasticity of the microenvironment. Many studies have demonstrated that extracellular forces can lead to rapid cytoskeletal remodeling, focal adhesion regulation, and intracellular signalling which can alter traction force dynamics. As well, cell migration, proliferation and stem cell fate are regulated by the ability of cells to sense the elasticity of their microenvironment through the generation of traction forces. In vitro studies have largely explored the influence of substrate elasticity and extracellular forces in isolation, however, in vivo cells are exposed to both mechanical cues simultaneously and their combined effect remains largely unexplored. Therefore, a series of experiments were performed in which cells were subjected to controlled extracellular forces as on substrates of increasing elasticity. The cellular response was quantified by measuring the resulting traction force magnitude dynamics. Two cell types were shown to increase their traction forces in response to extracellular forces only on substrates of specific elasticities. Therefore, cellular traction forces are regulated by an ability to sense and integrate at least two pieces of mechanical information - elasticity and deformation. Finally, this ability is shown to be dependent on the microtubule network and regulators of myosin-II activity.

description: Die Digitalisierung erfordert von industriellen Unternehmen, reaktionsfähig neue Kundenbedürfnisse zu bedienen. Der tägliche Umgang mit digitalen Technologien verändert die Erwartungen der Nutzer an Produkte und Services. Um im Wettbewerb zu bestehen, sind Geschäftsmodelle konsequent kundenorientiert auszurichten und permanent anzupassen. Innovationen ressourceneffizient und schnell in Form von Produkten und Services zu operationalisieren, setzt voraus, dass die Prozesse und Systeme von Unternehmen ein durchgängiges, anpassbares und transparentes Wissens-, Informations- und Datenmanagement gewährleisten. In dieser Arbeit wird ein Modell für ein strukturiertes Vorgehen entwickelt, um neue Geschäftsmodelle zu gestalten und die dafür notwendigen Adaptionen des Produktlebenszyklusmanagements vorzunehmen. Die Anforderungen an das Modell werden anhand der praxisbezogenen Aktionsforschung und qualitativer Untersuchungsmethoden abgeleitet. Darauf aufbauend erfolgt die Modellbildung, in die konkrete Techniken und Handlungsanleitungen einfließen. Anschließend wird das Modell durch den Use Case „Automatisiertes Laden“ evaluiert.

description: Abstract

A condition known as obesity is defined by an abnormal buildup of body fat. It occurs as a result of an imbalance between calories burned and calories ingested. Long-term disregard for this illness could result in serious complications such as fatty liver, cardiac problems, stroke, diabetes, and arthritis. Obesity’s rising prevalence causes more deaths globally. Controlling the complications has indeed been accomplished by treatment. This review will concentrate on using natural cures to manage obesity.

Sheehan's Conjecture

description: In 1975, Sheehan conjectured that every simple 4-regular hamiltonian graph has a second Hamilton cycle. If Sheehan's Conjecture holds, then the result can be extended to all simple d-regular hamiltonian graphs with d at least 3. First, we survey some previous results which verify the existence of a second Hamilton cycle if d is large enough. We will then demonstrate some techniques for finding a second Hamilton cycle that will be used throughout this paper. Finally, we use these techniques and show that for certain 4-regular Hamiltonian graphs whose automorphism group is large enough, a second Hamilton cycle exists.

description: Trade-offs between conflicting objectives are required in most real-world optimization problems. Decision-makers require an approximation of the Pareto frontier which illustrates the corresponding optimal compromises. This thesis develops algorithms that can provide these approximations effectively with provable quality guarantees. In the first part, an algorithm for bicriteria mixed-integer problems is developed. Based on the concept of patches, it is shown that the algorithm obtains an almost-optimal convergence rate. The second part starts with a discussion of algorithms for computing an approximation quality measure for Pareto frontiers. On this basis, a new multicriteria optimization algorithm for an arbitrary number of objectives is developed. Finally, models for multicriteria robust optimization are studied with a focus on supply chains. In various case studies, the proposed algorithms are applied to supply chain models, in particular regarding the objectives of costs and risks. The results show the large practical applicability of the approaches in this thesis.

description: Das Ziel der vorliegenden Bachelorarbeit lag auf der experimentellen Untersuchung zur Steigerung des Huminsäurengehaltes heimischer Braunkohlen mittels Hydrothermaler Carbonisierung (HTC). Hierzu wurden auf Basis der Untersuchungen von Cheng et al. eigene Versuche in einer Laboranlage durchgeführt. Untersucht wurde die Abhängigkeit des erreichbaren Huminsäurengehaltes vom eingesetzten KOH zu Kohleverhältnis als auch vom Wasser zu Kohleverhältnis. Hierzu wurde ein statistischer Versuchsplan erstellt. Bei den Prozessparametern Temperatur und Prozessdauer wurde sich an den in der Literatur beschriebenen optimalen Prozessparametern orientiert. Es konnte gezeigt werden, dass sich der Huminsäurengehalt heimischer Braunkohlen mit diesem Verfahren von 12,69% auf bis zu 85,4% steigern lässt. Ein weiteres Augenmerk lag auf der weiteren Prozessierung des HTC-Produktes. Untersucht wurden Möglichkeiten zur Rückführung der im HTC-Prozess eingesetzten KOH-Lösung. Sowohl die Rückführung der KOH-Lösung nach einer einfachen Fest-Flüssig-Trennung als auch nach einer sich daran anschließenden Membranfiltration lieferten dabei gute Ergebnisse. Es wurden Huminsäurengehalte von ca. 75 % erzielt. Auch konnte gezeigt werden, dass eine Vorbehandlung der Rohbraunkohle keine signifikant besseren Ergebnisse liefert. Hier lag der Huminsäurengehalt bei ca. 78 %. Die Bachelorarbeit liefert somit wichtige Erkenntnisse zur Steigerung des Huminäurengehaltes in heimischen Braunkohlen mittels HTC sowie mögliche Ansatzpunkte für weitere Untersuchungen hinsichtlich der Wirtschaftlichkeit des Gesamtverfahrens.

description: This thesis explores how religion is being represented, interpreted, and discussed in Canadian museums. It draws from a sample of thirty-one semi-structured interviews with curators and museum professionals and from the author’s own observations of fifty-one museums in eleven provinces and territories across Canada to explore the themes of space, power, and identity as they relate to religion in Canadian museums. Using the theories of sacred space created by Knott, this thesis explores how Canadian museums are capable of becoming sacred spaces based on their ability to give visitors numinous experiences, to act as contested spaces, and to serve as a location of religion. Canadian museums are powerful, as argued by Bourdieu and Foucault, by their very nature as places that produce and define knowledge, through claims to objectivity and an emphasis on a progress narrative, giving museums (and curators) power to define what is and is not religious by deciding whether and how to discuss the religious aspects of an artefact, object, or culture. Within the context of these two themes, museums enact Ricoeur’s theory of narrative identity by telling stories about different groups in order to create and communicate their identities. Some museums present a homogenous Canadian identity based on white mainline Christian identity while others explore the complexity of Canadian identity by telling the stories of non-mainstream religious or ethnic groups and their participation in Canadian history. Aboriginal peoples in Canada have become involved in the display of their traditions in larger museums and have started creating their own museums and cultural centres where their voices can take precedence.

description: Piezoelectric micromachined ultrasonic transducers (pMUTs) have been widely developed in recent years. The current trend goes towards a monolithic ASIC (application specific integrated circuit) integration as it results in a smaller chip area and thus larger variety of applications. To reduce the development time and consequently time-to-market as well as costs, virtual prototyping in form of FEM modelling has become a standardized practice in pMUT design. In this work, a pMUT device is designed and modelled for operation in 1 MHz∼10 MHz frequency range and a suitable time-gain-compensation (TGC) amplifier with automatic gain control (AGC) to compensate for the signal attenuation is developed. The coupling between the two design domains (pMUT and ASIC) on a simulation level is achieved as well. Additionally a novel interpolation method based on analytical physics-based equations aimed towards rapid prototyping of fluid-operated pMUTs is presented. The method allows for the definition of design variants, whose resonant frequencies match the target operating frequency and extraction of an optimal design w.r.t the largest transmitting sensitivity. The proposed TGC amplifier, designed for a 5 pF capacitive load and -20 dB∼20 dB gain range, experiences 20 MHz bandwidth at the highest gain setting, ±1 dB gain linearity error and consumes a total of 2.42 mW power. Adaptive gain change implemented by the AGC feedback, decreased the overall signal dynamic range to 10.3 dB, which is by almost a factor of 30 compared to an uncompensated signal.

description: This work describes the foundation to the microparticle simulation code PALADIN (PlasmA LAttice Dust INtegrator), mainly designed for studying microparticle contamination in arbitrary geometries. The theoretical foundation for PALADIN is derived in a detailed way by calculating various moments of the Maxwell-Boltzmann distribution in a plasma, leading to expressions for forces and currents acting on the microparticles. Then, the general functionality of PALADIN is discussed, with some specific examples presented to show the functionality of PALADIN, ranging from a simple box to more complicated geometries. Finally, the EOSS, a magnetron sputter coater, is used as a specific scenario to study the influence of microparticles on optical coatings.

description: Dans la foulée des débats entourant la définition et la compréhension de l’Acadie, dans ses dimensions identitaires et territoriales, cette thèse se veut un regard analytique sur l’adéquation entre la fête, le territoire et l’identité. Par l’étude du 4e Congrès mondial acadien tenu en août 2009 dans la Péninsule acadienne au Nouveau-Brunswick, nous cherchons à mieux cerner le rôle géographique de la fête, de même que son importance dans le développement des collectivités minoritaires comme l’Acadie. Ainsi, en étudiant trois terrains différents, soit le terrain géographique tel que dévoilé dans le jeu politique d’échelles performé par les organisateurs, celui des identités telles qu’elles sont exprimées dans le discours des participants et celui de l’action et des performances spatiales des gens et des paysages, nous tentons de démontrer que le CMA est une fête qui témoigne certes de l’ambivalence de l’Acadie et de nos sociétés contemporaines, mais dans un contexte qui se veut essentiellement culturel, unificateur et rassembleur. En ce sens, il se constitue un événement qui permet à la communauté de se vitaliser, de se renouveler et de s’ancrer non plus uniquement dans un passé trouble, mais dans un présent et un avenir riches de possibilités. Sans nécessairement trancher le débat, cette analyse se veut porteuse d’une réflexion positive pour la communauté acadienne, tout en permettant d’élargir le propos théorique et méthodologique sur la fête en géographie.

description: In dieser Arbeit wird mit Hilfe von durch BIM zur Verfügung gestellten Gebäudedaten ein Reglerentwurfverfahren für eine Heizkesselreglung eines Gebäudes mittels P-Regler entwickelt. Das verwendete Gebäude wird durch eine IFC-Datei beschrieben. Für den Entwurf werden für die Teile des Heizkreislaufs und die Gebäudeteile thermodynamische Modelle entwickelt, welche zusammen ein System gewöhnlicher partieller Differentialgleichungen bilden. Die physikalischen Größen, welche hierfür benötigt werden, werden, wenn vorhanden, aus der IFC-Datei extrahiert. Außerdem werden Scharen an Gebäudevarianten als IFC-Dateien generiert, um das Reglerentwurfverfahren später zu testen. Das gebildete Modell wird zur Überprüfung der Stabilität in einer Ruhelage mit vorgegebener Raumlufttemperatur linearisiert. Die Stabilität wird dann anhand des linearisierten Systems für verschiedene Reglerverstärkungen überprüft. Außerhalb des Arbeitspunkts wird die Stabilität mit Simulationsstudien untersucht. Das Reglerentwurfsverfahren erzeugt für das Beispielgebäude und die Gebäudevarianten zufriedenstellende Reglerparameter, die für stabiles Systemverhalten mit leichten stationären Regelabweichungen sorgen.
description: In this thesis, a controller design procedure for a P-controller to be used as a heating controller of a building is developed with the help of building data provided by BIM. The building used is described by an IFC file. For the design, thermodynamic models are developed for the parts of the heating circuit and the building, which together form a system of ordinary partial differential equations. The physical quantities needed for this are extracted from the IFC file, if available. In addition, families of building variants are generated in the form of IFC files to test the controller design procedure later. The model formed is linearized to check stability at an equilibrium point with a given room air temperature. The stability is then checked using the linearized system for different controller gains. Outside the operating point, stability is also tested with simulation studies. The controller design procedure produces satisfactory controller parameters for the example building and building variants, providing stable system behavior with slight steady-state control deviations.

description: Coordinating the motion of multiple automated vehicles in a delimited area - or, more generally, multiple moving objects in a shared workspace - is a standing challenge in robotics research. In this thesis, approaches for the coordination of multiple mobile robots are investigated and extended to enable automation of large vehicles such as self-driving trucks with trailers operated in logistics distribution centers. Many existing algorithms are limited to simple circular or car-like geometries, which leads to unsatisfactory results for larger vehicle combinations. In the algorithms presented in this thesis, the limitation to simple geometries is overcome by introducing spatiotemporal occupancy tracking that allows for precise coordination of complex vehicle combinations. Various algorithms for deriving coordinated trajectories are presented, evaluated and extended. As disturbances in the execution of coordinated motion plans cannot be excluded in real-world applications, techniques for handling such disturbances are elaborated and tested. All contributions are combined in a software framework that is ready for deployment to real-world applications.

description: The number of personal relationships occurring via the Internet is increasing as more people gain access to it. Many of these relationships are romantic in nature, and evidence is accumulating that they have the potential to have an adverse effect on existing face-to-face relationships. This study explored the formation of romantic relationships on their Internet, their nature, and their possible impact on existing marital or de facto relationships in a sample of 75 adults (mean age 42 years, SD = 11.1 years) who responded to an online survey of individuals involved in extradyadic relationships on the Internet. Respondents reported a variety of means of contacting their online partner. More females than males communicated with them daily. Most respondents knew what their partner looked like, most had contacted them by telephone, and a third had met them. Most reported more satisfaction with their online relationship than with their face-to-face one, though few said that it was more important to them than their primary relationship. Although only a quarter of the sample admitted that their online relationship had affected their primary one, those participants reported concealing the truth about the time or nature of their activities, that everyday tasks did not get done, and that levels of sexual intimacy with their primary partner had dropped. The nature of these and other problems suggests that therapists should be aware of the potential for Internet relationships to seriously affect face-to-face relationships.

description: Space Situational Awareness (SSA) by ground-based digital-array radar systems has been attracting global attention in recent years. One of its fundamental tasks is to provide accurate collision forecasting between space debris and active satellites, leading to increased avoidance probability. This is achieved by a rigorous signal processing stage that successfully detects stray space debris and accurately estimates its parameters from the radar data: range, direction-of-arrival, radial velocity, etc. The objective of this research is to improve the radar performance through the adaptation of the signal processing scheme to SSA. It presents the shortcomings of several key aspects of traditional signal processing and proposes new methods for improved target detection and parameter estimation, supported by numerical demonstrations of a real radar system. The above-mentioned techniques ultimately lead to superior estimation accuracy, higher resource efficiency, and robust detection capabilities, contributing to enhanced SSA. Based on this research, new estimation methods and operational modes can be explored in the context of a single station and radar networks, leading to a safer near-Earth space.

description: The design of digital ecosystems requires the simultaneous consideration of multiple stakeholder groups which leads to complex processes and systems. In practice, the lack of methodological support for the design of digital ecosystems, including the identification of stakeholders and the derivation of requirements, leads to inappropriate business models and insufficient software support. From a scientific perspective, the specificities of digital ecosystems that require an adaptation of software engineering practices are not fully understood. In this research, an approach to support the derivation of requirements for digital platforms was developed to support the design and realization of digital ecosystems. The approach facilitates the gathering of relevant information in digital ecosystems and enables the creation of corresponding representations that document the information appropriately.

description: In two pre-registered studies, we tracked changes in individuals’ feelings of social connection during the COVID-19 pandemic. Both studies capitalized on measures of social connection and well-being obtained prior to the COVID-19 pandemic by recruiting the same participants again in the midst of the pandemic’s upending effects. Study 1 included a sample of undergraduates from a Canadian university (N = 467), and Study 2 included community adults primarily from the United States and the United Kingdom (N = 336). Our results suggest that people experienced relatively little change in feelings of social connection in the face of the initial reshaping of their social lives caused by the COVID-19 pandemic. Exploratory analyses suggested that relatively extraverted individuals exhibited larger declines in social connection. However, after controlling for levels of social connection prior to the pandemic (as pre-registered), the negative effect of extraversion reversed (Study 1) or disappeared (Study 2).

Zur Auslegung von Dickschicht-Aktoren werden grundlegende Kenntnisse über die elektromechanischen Eigenschaften benötigt. Diese Arbeit beschreibt die elektromechanischen Eigenschaften piezokeramischer Dickschichten unter Klein- und Großsignalbedingungen. Durch gezielte Variationen der Biegerlänge und Materialien werden Einflüsse auf die Gefügeentwicklung, das Arbeitsvermögen und weitere elektromechanische Kennwerte beschrieben und optimale Herstellungsparameter identifiziert. Interdigitalelektroden (IDE) ermöglichen die Polarisation und Ansteuerung der piezokeramischen Schicht in der Ebene (in-plane). Aufgrund des das-Effektes kommt es zur Dehnung in der Ebene, woraus eine Verdopplung der Biegung in entgegengesetzter Richtung zu through-thickness-Aktoren resultiert. In der Arbeit wird das Arbeitsvermögen siebgedruckter in-plane-Biegeaktoren in Abhängigkeit vom Substratmaterial, von der Biegerlänge und vom piezokeramischen Material beschrieben und diskutiert. An zwei Mikropositioniersystemen wird die Eignung piezokeramischer Dickschichtaktoren für adaptive optische Systeme gezeigt.

description: Subfamily Brotheinae Simon, 1879, new rank   Type Genus. Brotheas C. L. Koch, 1837. Synonyms.
 Belisariinae Lourenço, 1998, new synonymy (valid as tribe name).
 Composition. This subfamily is established here. It includes two tribes, Brotheini (four genera) and Belisariini (one genus).
 Distribution. Europe, South America.
 Taxonomic history. The name Brotheidae, based on the type genus Brotheas C.L. Koch, 1837, is here taken out of synonymy (Sissom, 2000a: 288). It was never used as a valid family-group name since suggested by Simon (1879: 92) as a family Broteidae (incorrect original spelling), but remained an available synonym. Its establishment as a subfamily does not enable priority of Brotheidae Simon, 1879 over Chactidae Pocock, 1893 and Chactoidea Pocock, 1893; this situation is specifically addressed by the Article 35 of the Code (ICZN, 1999): “After 1999, if a family group name is older than a prevailing name for a higher family group rank, it does not displace the junior name”.
 Biogeographic history. Disjunct range of Brotheinae is a remarkable relict feature, paralleled in scorpions at the subfamily level only in Scorpiopinae and Diplocentrinae. Both the European Belisariini (a single monotypic genus Belisarius) and the South American Brotheini could be relicts of much earlier (Pangean?) distribution of Chactidae. Disjunct distribution of some South American genera of Brotheini can be attributed to the recent (Pleistocene) fluctuations of tropical rainforest (Lourenço, 1988, 1994, 1996b; Monod & Lourenço, 2001).
 Diagnosis. Synapomorphies.

description: Превышение предельно допустимых концентраций в воде химических веществ (фосфатов, фторидов, марганца, стронция, свинца) приводит к повышению уровня онкомаркеров: раковоэмбрионального антигена, альфафетопротеина, простат-специфического антигена и опухолево-ассоциированного поверхностного антигена и, следовательно, может повысить риск развития онкопатологических заболеваний.

Haftflüssigkeit

description: Nasshaftung ist in der Natur weit verbreitet. Von Nasshaftung wird dabei gesprochen, wenn zwei Oberflächen durch eine sich zwischen ihnen befindende Flüssigkeitsschicht aneinander haften. Durch dieses Prinzip ist es möglich, ohne großen Kraftaufwand sowohl auf rauen als auch auf glatten Flächen zu haften, auch wenn diese feucht oder überflutet sind. In dieser Arbeit werden die Grundlagen der Nasshaftung zusammengefasst und verschiedene Einflüsse auf diese experimentell untersucht. Dafür werden die Nasshaftungskräfte zwischen einem Stempel und einer ebenen Platte gemessen. Es wurden unterschiedliche Oberflächen und verschiedene Haftflüssigkeiten miteinander verglichen. Es zeigte sich, dass die Nasshaftungskräfte umso größer sind, je größer die Viskosität der Haftflüssigkeit ist. Außerdem wird die Nasshaftung wesentlich durch den Abstand zwischen den beiden Oberflächen beeinflusst.

Common data model

description: Parkinson’s disease poses significant research challenges due to its biological complexity. While cohort studies have advanced our understanding, they often suffer from biases related to selection criteria and inconsistent naming systems across studies. Effective exploration of Parkinson’s disease, via cross-cohort analyses, requires rigorous data harmonization to enhance the generalizability of findings. Previous initiatives, such as the Observational Medical Outcomes Partnership and the Common Data Element Catalog, have made strides but did not fully address the specific needs of Parkinson’s disease research. To tackle these issues, we developed PASSIONATE, a common data model tailored for the Parkinson’s disease research community. PASSIONATE emphasizes the unique aspects of Parkinson’s disease data and cross-referenced with existing ontologies where applicable to further standardize the naming system. Additionally, we created PDataViewer, a web application that helps researchers locate suitable cohort studies based on variable queries. This tool enhances the visualization of biomarker distributions and provides insight into participant drop-off rates. PDataViewer includes an auto-harmonization tool that streamlines the semantic harmonization of cohort data, allowing users to align variables with PASSIONATE-defined terms as well as those from other cohorts. It employs a vector database for semantic harmonization, ensuring scalability and efficiency. By facilitating the identification of comparable cohorts, PDataViewer is crucial for conducting cross-cohort analyses, improving transparency in patient-level data. The separation of backend and frontend components enhances participant data security, addressing privacy concerns that are common in cohort studies. Overall, the introduction of PASSIONATE and PDataViewer improves the findability, interoperability, and transparency of data in Parkinson’s disease research, potentially paving the way for federated learning approaches in the field.

description: Este trabajo analiza la seguridad de abastecimiento energético de la Unión Europea desde una perspectiva transversal y dimensional. En primer lugar, se revisa la literatura académica referente a la seguridad energética europea, así como las alusiones realizadas en los sucesivos Tratados de la Unión, con el fin de delimitar el concepto objeto de análisis. A continuación, se practica un análisis con una combinación de técnicas cualitativas y cuantitativas para detectar la situación actual y la posible evolución futura de la seguridad de suministro. En esta fase analítica, se añaden elementos que no suelen tenerse en cuenta en otras investigaciones afines, como los condicionantes socioeconómicos y medioambientales. Finalmente, se recogen las principales medidas políticas propuestas para incrementar la seguridad en los diferentes horizontes temporales, prestando especial atención a la construcción de la Unión de la Energía.

Lumbar spine

description: Lacrosse, Canada’s national summer sport, is a sport anchored in first nations’ tradition. Its growing popularity in North America has not been reflected by a similar interest in the scientific literature more specifically on the biomechanics of the lumbar spine with its throwing motion. The aim of this study was to describe the motions, forces and muscle actions of the lumbar spine with the hybrid, overhand and sidearm throw. Twelve subjects were asked to throw at maximal speed while captured by a 3D motion analysis system. Flexion, extension and axial rotation angular velocities as well as positive and negative powers in the two planes were calculated. The first research question pertained to consistency in angular velocities and powers between trials of a given throwing technique. Subjects showed a fairly high variation on all variables but mostly with the angular velocities in extension and the peak positive power in flexion/extension which had high coefficient of variations (CVs). The contralateral rotation velocity and the positive rotation power had the lowest CVs. Overall the CVs for powers exceeded the angular velocities’. The second research question addressed if a difference in variables was present between the three throwing methods. A significant difference was observed in the peak negative power in flexion/extension and the peak positive power in rotation. The contralateral rotation angular velocity also showed a significant difference but the sphericity assumption failed. No other variable showed a significant difference but the observed power for those variables was also quite small. Due to the lack of power and the further need for controlling some unforeseen sources of error, this study can be used as a pilot study to further define and improve future studies in the field of lacrosse biomechanics.
The study of differential 8-PSK trellis-coded modulation in indoor wireless communications through computer simulation.

Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis work studies the use of 4- and 8-state trellis-coded modulation with phase-shift keying and non-coherent, differential signaling for digital indoor wireless communications, at an operating frequency of 1.5 GHz and a transmission rate of 10 Mbits/s. Many other modulation schemes have been considered for the indoor wireless channel in other studies, and trellis-coded modulation has been considered for the satellite and mobile channel. This study presents new BER performance results, obtained through computer simulations, that suggest a performance gain with TCM relative to DQPSK, for certain ranges of SNR and rms delay spread. Equalization is also considered, and it is shown that it can provide considerable performance gain.
Mel Gibson's passion and 'The Passion of the Christ'

description: For weeks there seemed to be scarcely a day when the papers weren't fuelling the publicity surrounding the film by drawing attention either to the inflammatory outbursts of various interest groups or to the secrecy relating to its pre-release screenings. We usually acquire some sort of baggage from the hype attached to major films: it is in the producers' interests to try to ensure this: but what went on before The Passion actually hit the screens was something else again.

description: Background Child undernutrition is a global health issue that is associated with poor sanitation and an altered intestinal microbiota. Immunoglobulin (Ig) A mediates host-microbial homeostasis in the intestine, and acutely undernourished children have been shown to have altered IgA recognition of the fecal microbiota. We sought to determine whether chronic undernutrition (stunting) or intestinal inflammation were associated with antibody recognition of the microbiota using two geographically distinct populations from the Afribiota project. Fecal bacteria from 200 children between 2 and 5 years old in Antananarivo, Madagascar, and Bangui, Central African Republic (CAR), were sorted into IgA-positive (IgA+) and IgA-negative (IgA−) populations by flow cytometry and subsequently characterized by 16S rRNA gene sequencing to determine IgA-bacterial targeting. We additionally measured IgG+ fecal bacteria by flow cytometry in a subset of 75 children. Results Stunted children (height-for-age z-score ≤ −2) had a greater proportion of IgA+ bacteria in the fecal microbiota compared to non-stunted controls. This trend was consistent in both countries, despite the higher overall IgA-targeting of the microbiota in Madagascar, but lost significance in each country individually. Two of the most highly IgA-recognized bacteria regardless of nutritional status were Campylobacter (in CAR) and Haemophilus (in both countries), both of which were previously shown to be more abundant in stunted children; however, there was no association between IgA-targeting of these bacteria and either stunting or inflammatory markers. IgG-bound intestinal bacteria were rare in both stunted and non-stunted children, similar to levels observed in healthy populations. Conclusions Undernourished children carry a high load of intestinal pathogens and pathobionts. Our data suggest that stunted children have a greater proportion of IgA-recognized fecal bacteria. We moreover identify two putative pathobionts, Haemophilus and Campylobacter, that are broadly targeted by intestinal IgA. This study furthers our understanding of host-microbiota interactions in undernutrition and identifies immune-recognized microbes for future study.
