Ecology and fisheries of seamount ecosystems

description: This thesis explores some fundamental questions about seamount ecology and fisheries. Initially, I characterized the seamount distribution on the Azores Exclusive Economic Zone using two bathymetry datasets. The algorithm developed was able to map and describe 63 large and 332 small seamount-like features in the EEZ of the Azores. The distribution suggests that large proportion of seamounts occur in chains along the Mid Atlantic Ridge, however, few isolated seamounts are also present in the Azores. In clarifying how seamounts affect primary productivity, I show that primary production enhancement is not sufficient to support often-observed large aggregations of fish. My work supports an alternative hypothesis, that a horizontal flux of prey is the key factor in sustaining rich communities living on seamounts. Additionally, the importance of seamounts to some large pelagic fish, marine mammals and seabirds is also demonstrated. In the case of skipjack and bigeye tuna, common dolphin and Cory's shearwater, these species were significantly more abundant in the vicinity of some seamount summits. I found that seamounts may act as feeding stations for some of these visitors. The methodology developed, however, failed to demonstrate seamounts' association for bottlenose dolphins, spotted dolphin, sperm whale, terns, yellow-legged gull, and loggerhead sea turtles. Fisheries exploitation is a major threat to seamount ecosystems, but I am not presently able to quantify the amount of catches taken from seamounts around the world. Instead, 1 demonstrate that global landings of demersal marine fishes have shifted to deeper water species over the last 50 years, an indirect indication that seamounts have also increased in importance. Moreover, I show that 'deep-water', 'seamount' and 'seamount-aggregating' fish stocks may be at serious risk of depletion, since their life histories render them highly vulnerable to overfishing with little resilience to overexploitation. Finally, ecosystem modelling analyses indicate that sustainable seamount fisheries with tolerable ecosystem impacts can be found only by maximizing an 'ecological' objective function. This suggests that industrial fisheries are not viable on seamounts. However, regulated small-scale artisanal fishing fleets could be sustained by seamount ecosystems.

description: Manejar las expectativas de los consumidores para los alimentos con marcas de origen de calidad genera una efiencia superior a la obtenida si unicamiente se tienen en cuenta elementos de calidad objetiva. Sin embargo, conocer la inferencia de calidad subjetiva de esta categoria de alimentos que genera el consumidor no es tarea facil, porque se mezclan en la marca de origen calores simbolicos y emocionales, como la tradicion, la autenicidad, el patrimonia, la cultura; con aspectos del producto como la particularidad del proceso, sus componentes hedonicas, su incidencia en la salud, la garantia generada y su conveniencia de utilizacion. El grado de conocimiento del consumidor de la region, del producto y su experiencia pasada, moderada pr sus valores cilturales y su actitud hacia la alimentacion, marcaran su interes por esta categoria de productos, yendo desde el extremo de los habilidosos identidicados por arquetipos, a los mas alejados asociados con los estereotipos. En todo caso, la globalizacion de los mercados, el continuo proceso de innocacion del sector, la estructura habitual del sector productor y las modificaciones de los patrones culturales y de costumbres, puede limitar las posibilidades de estos alimentos, con rasgos de etnocentrismo, como elemento de desarrollo rural, enfrentados ademas a demandas generalmentre reducidas...Working in the consumer expectations to food quality with origin labels is more efficient than only to analyse the objective quality with origin labels is more efficient than only to analyse the objective quality elements. However, to know the subjective quality inference of the consumer is difficult, because into the region quality labels coexist symbolic and emotional values, like tradition, authenticity, heritage or culture; with other product aspects specially the process particularities, hedonic components, health incidence, guarantee appreciate and convenience aptitude. The knowledge level of the region, product and past experience, moderates by cultural values and food attitude, affects to the interest and less experts associated with 'stereotypes'. But, the globalisation of the markets, the continuous food sector innovation process, the classical supply structure and the evolution of the cultural and food habits, could limited the influence of these ethnocentric products on the rural development, besides in front to a reduced demand segments.

description: We present a formulation of chiral gauge theories, which admits more general spectra of Dirac operators and reveals considerably more possibilities for the structure of the chiral projections. Our two forms of correlation functions both also apply in the presence of zero modes and for any value of the index. The decomposition of the total set of pairs of bases into equivalence classes is carefully analyzed. Transformation properties are derived.

description: The picosecond geminate recombination kinetics for hydrated electrons generated by 200 nm two photon absorption (12.4 eV total energy) has been measured in both light and heavy water. The geminate kinetics are observed to be almost identical in both H2O and D2O. Kinetic analysis based upon the independent reaction time approximation indicates that the average separation between the electron and its geminate partners in D2O is 13% narrower than in H2O (2.1 nm vs. 2.4 nm). These observations suggest that, even at this high ionization energy, autoionization of water competes with direct ionization.

description: A szövetkezeti hitelintézetek 160 éve vannak jelen Magyarországon, és az 1950-es évek elején végrehajtott állami felszámolásukat követően újraélesztett takarékszövetkezetek is már közel 60 éve bizonyítják életképességüket, de a hazai gazdaságot a válság kirobbanása óta jellemző alulfinanszírozottság új feladatok elé állítja ezeket. Míg az ezredfordulón alig több mint 4%-os piaci részesedéssel rendelkeztek a mezőgazdaság finanszírozásában, addig napjainkban ez az arány már 15 és 20% között mozog. Az írás a szövetkezeti hitelintézetek agrárfinanszírozással összefüggő kérdéseit vizsgálja, és arra igyekszik rámutatni, hogy egyrészről hagyományaiknál, lehetőségeiknél és sajátosságaiknál fogva kifejezetten alkalmasak a magyar agrárgazdaság finanszírozására, másrészről ennek érdekében meg kell szüntetni az akadályokat, amik gátolják szerepvállalásukat e területen. Ezek közül a két legjelentősebb a hálózatszerű működés kialakítása, másrészről a szolgáltatási színvonal egységesítése, melyek nélkül a szövetkezeti szektor nem lesz képes jelentős mértékben növelni piaci részesedését. Emellett a leírtak alapján a hazai szövetkezeti hitelintézeteknél is igazolva látjuk, hogy a szektor és szereplőinek gazdasági kiegyenlítő erejét is figyelembe véve a takarékszövetkezetek szerepének újragondolása, aktivitásuk, részesedésük növelése pártolandó.------------------------Cooperative Banks have existed in Hungary for more than 160 years, and the re-newed Savings Cooperatives have been demonstrating for 60 years the reason for their existence, but the under-financing of the domestic economy, which is symptomatic in Hungary during the financial crisis, gives them a lot of new tasks. The Co-operatives had around 4 % of market share in rural loans in 2000 but currently this figure is be-tween 15 and 20 %. This paper researches the questions of rural financing connected with Co-operative banks and shows that they are capable of resolving the financial problems of Hungarian agriculture by means of their traditions, facilities and particu-larities. The most important tasks are the creation of a network and to standardise their services because, without these steps, the sector will not be capable of increasing its market share. On the basis of the results presented in this paper it seems to be con-firmed that, considering the countervailing power of the Co-operatives, their role needs rethinking and supporting in order to increase both their activities and their market share.

description: This paper describes the National Research Council (NRC) Word Sense Disambiguation (WSD) system, as applied to the English Lexical Sample (ELS) task in Senseval-3. The NRC system approaches WSD as a classical supervised machine learning problem, using familiar tools such as the Weka machine learning software and Brill's rule-based part-of-speech tagger. Head words are represented as feature vectors with several hundred features. Approximately half of the features are syntactic and the other half are semantic. The main novelty in the system is the method for generating the semantic features, based on word \hbox{co-occurrence} probabilities. The probabilities are estimated using the Waterloo MultiText System with a corpus of about one terabyte of unlabeled text, collected by a web crawler.

Experimental evaluation of manufacturing parameters on the structural performance of rounded dovetail connections
Creators: name: Anastas, Hiba
Publisher: name: University of British Columbia
Year: 2011

description: The revival of timber framing in recent years and the development of computer numerically controlled (CNC) machines have led to a number of research projects and related studies on traditional timber joinery. This paper examines the experimental evaluation of the structural performance of rounded dovetail connections. The study investigates four different climatic conditions to evaluate their influence on the load carrying capacity, stiffness, and failure modes o f single and double dovetail joints under static shear loading. The study also examines the effect of manufacturing tolerances such as machining speed and joint tightness (tight joint versus loose joint) on the overall performance of the dovetail joints. It was found that the specimens manufactured and tested in the dry condition outperformed the specimens evaluated under the other climatic conditions. In the study of different manufacturing tolerances, it was determined that the joints produced at low speed and without a gap had a higher capacity than those produced at higher speed and with a gap.

description: `Hot jupiters,' giant planets with orbits very close to their parent stars, are thought to form farther away and migrate inward via interactions with a massive gas disk. If a giant planet forms and migrates quickly, the planetesimal population has time to re-generate in the lifetime of the disk and terrestrial planets may form (Armitage 2003). We present results of simulations of terrestrial planet formation in the presence of hot jupiters, broadly defined as having orbital radii <= 0.5 AU. We show that terrestrial planets similar to those in the Solar System can form around stars with hot jupiters, and can have water contents equal to or higher than the Earth's. For small orbital radii of hot jupiters (e.g. 0.15, 0.25 AU) potentially habitable planets can form, but for semi-major axes of 0.5 AU or greater their formation is suppressed. We show that the presence of an outer giant planet such as Jupiter does not enhance the water content of the terrestrial planets, but rather decreases their formation and water delivery timescales. We speculate that asteroid belts may exist interior to the terrestrial planets in systems with hot jupiters.

description: In recent years, machine learning (ML) and neural networks (NNs) have gained widespread use and attention across various domains, particularly in transportation for achieving autonomy, including the emergence of flying taxis for urban air mobility (UAM). However, concerns about certification have come up, compelling the development of standardized processes encompassing the entire ML and NN pipeline. This paper delves into the inference stage and the requisite hardware, highlighting the challenges associated with IEEE 754 floating-point arithmetic and proposing alternative number representations. By evaluating diverse summation and dot product algorithms, we aim to mitigate issues related to non-associativity. Additionally, our exploration of fixed-point arithmetic reveals its advantages over floating-point methods, demonstrating significant hardware efficiencies. Employing an empirical approach, we ascertain the optimal bit-width necessary to attain an acceptable level of accuracy, considering the inherent complexity of bit-width optimization.

description: Die vorliegende Masterarbeit beschäftigt sich mit dem Entwurf eines Wohnbaukomplexes in Seoul. Die südkoreanische Hauptstadt gehört mit ihren 10 Mio. Einwohner zu den am dichtest besiedelten Metropolen der Welt. Aus diesem Grund gelten Wohnflächen als besonders selten, bzw. teuer. Der Bauplatz befindet sich im Bezirk Seocho. Dieser befindet sich westlich vom Bezirk Gangnam und grenzt an der südlichen Seite des Flusses Han. Anhand eines fiktiven Projektes werden verschiedene Lösungen für den Mangel an Wohn- und Grünflächen erforscht. Trotz günstigen Mietpreisen soll hochwertiges Wohnen durch ein gemischtes Raumprogramm entstehen, ohne dabei die Eigenschaften der koreanischen Wohnweise zu vernachlässigen. Hierbei wird besonders viel Wert auf die stets wachsende Nachfrage der Einzimmerwohnungen und deren Einrichtung gelegt. Durch die besondere Anordnung dieser Wohneinheiten entstehen dreidimensionale Wellen, die sich an die vorhandene Bergsilhouette von Seoul anlehnen. Gleichzeitig sorgen architektonische Lösungen dafür, dass verschiedene Haushaltsstrukturen aufeinandertreffen und sich bestenfalls austauschen. Des Weiteren werden anhand dieser Arbeit auf bestehende Probleme im Straßenverkehr und in der Arbeitswelt hingewiesen. Eine fast Auto-lose-Nachbarschaft wird angeboten, die unter anderem auch die kontroverse Work-Life-Balance in Seoul verbessert. Fußgänger statt Autofahrer und Freizeit statt Stress. So entsteht eine quasi -autofreie- Mikrostadt namens -PIXELATED MICROCITY-.
description: This master thesis deals with the design of a residential complex in Seoul. With its 10 Million inhabitants, the South Korean capital has one of the highest population densities in the world. For this reason, living areas are considered particularly rare and expensive. The site is located in Seocho district, located to the west of the Gangnam district, bordering the southern side of the Han River. Based on an imaginary project, multiple solutions for the lack of residential space and green areas are being explored. Despite low rental housing prices, high quality living and mixed functions are being created, while keeping an eye on Korean culture. Furthermore, the thesis focuses on the rise of single households and several experiments are being made on very compact single home units. The playful combination of these units, also called -Pixels-, creates three-dimensional waves, that fade into the hilly panorama of Seoul, also known as the Green Belt. At the same time, spatial configurations ensure that different households can meet and socialize. Thus, a particular attention is drawn on the high traffic commute in Seoul and its controversial work-life balance. In a new self-contained neighborhood, where pedestrians have more freedom than car drivers, where lost time in traffic jams becomes leisure time, and where stress converts into productivity, an almost car-less neighborhood, named -PIXELATED MICROCITY-, is born.
Reconstructing the evolution of white dwarf binaries: further evidence for an alternative algorithm for the outcome of the common-envelope phase in close binaries

description: We determine the possible masses and radii of the progenitors of white dwarfs in binaries from fits to detailed stellar evolution models and use these to reconstruct the mass-transfer phase in which the white dwarf was formed. We confirm the earlier finding that in the first phase of mass transfer in the binary evolution leading to a close pair of white dwarfs, the standard common-envelope formalism equating the energy balance in the system, does not work. An algorithm equating the angular momentum balance can explain the observations. This conclusion is now based on ten observed systems rather than three. With the latter algorithm the separation does not change much for approximately equal mass binaries. Assuming constant efficiency in the standard α-formalism and a constant value of γ, we investigate the effect of both methods on the change in separation in general and conclude that when there is observational evidence for strong shrinkage of the orbit, the γ-algorithm also leads to this. We then extend our analysis to all close binaries with at least one white dwarf component and reconstruct the mass transfer phases that lead to these binaries. We find that all observations can be explained with a single value of γ, making the γ-algorithm a useful tool to predict the outcome of common-envelope evolution. We discuss the consequences of our findings for different binary populations in the Galaxy, including massive binaries, for which the reconstruction method cannot be used (abbriged).

description: A szövetkezetek befektetői tulajdonú vállalkozássá alakulása fontos kérdés nem csak az elmélet, de a szövetkezet tagjai/tulajdonosai szempontjából is. Szükségszerű-e ez az átalakulás akkor, amikor a szövetkezet elér egy bizonyos fejlettségi szintet? Át kell-e alakulni a működés biztosítása miatt, vagy ez választási lehetősége a tulajdonosi körnek? A tanulmány ezt a kérdést vizsgálja, valamint azt, hogy azok az átalakulások, amelyeket leírtak a szakirodalomban, a szövetkezeti forma alapvető jellegzetességei miatt vagy egyéb okokból mentek végbe. A hipotézisek vizsgálata alapján megállapítható, hogy a szövetkezet átalakulása nem szükségszerű folyamat, a keletkezett jellegzetes hatékonysági problémák megoldhatók egyéb eszközökkel is. A második hipotézis, mely szerint a szövetkezeti átalakulásnak nem a szövetkezet alapvető hatékonysági gyengesége az oka, hanem egyéb okok is szerepet játszanak, részben igazolható a fentiek alapján, de nem teljesen. Kérdéses, hogy a „szövetkezeti előnyök” meddig képesek hatékonyan támogatni a gazdasági tevékenységet és kiküszöbölni a strukturális jellegzetességek okozta nehézségeket.---------------------------Transformation of cooperatives into investor owned firms is an important question not just from a theoretical point of view but also because of the member/owners. Is it an unavoidable necessity when the cooperative achieves a certain level of development; does it have to transform to ensure secure operations, or is it a conscious choice of the owners? The article examines this problem and those transformations that were de-scribed in the literature: why did they occur, because of the inherent characteristics of the cooperative form or for other reasons? Based on hypotheses checking it can be said that transformation of the cooperative is not an absolute necessity, solving the effi-ciency problems can be done with other measures. The second hypothesis, that the cause of cooperative transformation is not the inherent inefficiency of the cooperative form, but for other reasons, can be only partially verified. It is questionable for how long the cooperative advantage can support business activities and aid in eliminating the problems caused by structural characteristics.

description: We extend a bottom up holographic model, which has been used in studying the color superconductivity in QCD, to the imaginary chemical potential ($μ_I$) region, and the phase diagram is studied on the $μ_I$-temperature (T) plane. The analysis is performed for the case of the probe approximation and for the background where the back reaction from the flavor fermions are taken into account. For both cases, we could find the expected Roberge-Weiss (RW) transitions. In the case of the back-reacted solution, a bound of the color number $N_c$ is found to produce the RW periodicity. It is given as $N_c\geq 1.2$. Furthermore, we could assure the validity of this extended model by comparing our result with the one of the lattice QCD near $μ_I=0$.

description: Core-periphery structure is an essential mesoscale feature in complex networks. Previous researches mostly focus on discriminative approaches while in this work, we propose a generative model called masked Bayesian non-negative matrix factorization. We build the model using two pair affiliation matrices to indicate core-periphery pair associations and using a mask matrix to highlight connections to core nodes. We propose an approach to infer the model parameters, and prove the convergence of variables with our approach. Besides the abilities as traditional approaches, it is able to identify core scores with overlapping core-periphery pairs. We verify the effectiveness of our method using randomly generated networks and real-world networks. Experimental results demonstrate that the proposed method outperforms traditional approaches.

The evolution equation is given by $$X_{t}=\frac{1}{\sqrtτ} \textbf{B}$$ where $τ$ is the torsion and $\textbf{B}$ is the unit binormal vector. In the case of constant curvature, we find all of the stationary solutions and linearize the PDE for torsion around stationary solutions admitting an explicit formula. Afterwards, we prove the $L^2(\mathbb{R})$ linear stability of the stationary solutions corresponding to helices with constant curvature and constant torsion.

description: We report the experimental observation of the spin-Hall effect in a two-dimensional (2D) hole system with Rashba spin-orbit coupling. The 2D hole layer is a part of a p-n junction light-emitting diode with a specially designed co-planar geometry which allows an angle-resolved polarization detection at opposite edges of the 2D hole system. In equilibrium the angular momenta of the Rashba split heavy hole states lie in the plane of the 2D layer. When an electric field is applied across the hole channel a non zero out-of-plane component of the angular momentum is detected whose sign depends on the sign of the electric field and is opposite for the two edges. Microscopic quantum transport calculations show only a weak effect of disorder suggesting that the clean limit spin-Hall conductance description (intrinsic spin-Hall effect) might apply to our system.

description: Spoken language understanding (SLU) is a key component of task-oriented dialogue systems. SLU parses natural language user utterances into semantic frames. Previous work has shown that incorporating context information significantly improves SLU performance for multi-turn dialogues. However, collecting a large-scale human-labeled multi-turn dialogue corpus for the target domains is complex and costly. To reduce dependency on the collection and annotation effort, we propose a Context Encoding Language Transformer (CELT) model facilitating exploiting various context information for SLU. We explore different transfer learning approaches to reduce dependency on data collection and annotation. In addition to unsupervised pre-training using large-scale general purpose unlabeled corpora, such as Wikipedia, we explore unsupervised and supervised adaptive training approaches for transfer learning to benefit from other in-domain and out-of-domain dialogue corpora. Experimental results demonstrate that the proposed model with the proposed transfer learning approaches achieves significant improvement on the SLU performance over state-of-the-art models on two large-scale single-turn dialogue benchmarks and one large-scale multi-turn dialogue benchmark.

description: We investigate the gravitational collapse of rapidly rotating relativistic supermassive stars by means of a 3+1 hydrodynamical simulations in conformally flat spacetime of general relativity. We study the evolution of differentially rotating supermassive stars of $q \equiv J/M^{2} \sim 1$ ($J$ is the angular momentum and $M$ is the gravitational mass of the star) from the onset of radial instability at $R/M \sim 65$ ($R$ is the circumferential radius of the star) to the point where the conformally flat approximation breaks down. We find that the collapse of the star of $q \gtrsim 1$, a radially unstable differentially rotating star form a black hole of $q \lesssim 1$. The main reason to prevent formation of a black hole of $q \gtrsim 1$ is that quite a large amount of angular momentum stays at the surface. We also find that most of the mass density collapses coherently to form a supermassive black hole with no appreciable disk nor bar. In the absence of nonaxisymmetric deformation, the collapse of differentially rotating supermassive stars from the onset of radial instability are the promising sources of burst and quasinormal ringing waves in the Laser Interferometer Space Antenna.

description: Accurate prediction of wind speed and power is vital for enhancing the efficiency of wind energy systems. Numerous solutions have been implemented to date, demonstrating their potential to improve forecasting. Among these, deep learning is perceived as a revolutionary approach in the field. However, despite their effectiveness, the noise present in the collected data remains a significant challenge. This noise has the potential to diminish the performance of these algorithms, leading to inaccurate predictions. In response to this, this study explores a novel feature engineering approach. This approach involves altering the data input shape in both Convolutional Neural Network-Long Short-Term Memory (CNN-LSTM) and Autoregressive models for various forecasting horizons. The results reveal substantial enhancements in model resilience against noise resulting from step increases in data. The approach could achieve an impressive 83% accuracy in predicting unseen data up to the 24th steps. Furthermore, this method consistently provides high accuracy for short, mid, and long-term forecasts, outperforming the performance of individual models. These findings pave the way for further research on noise reduction strategies at different forecasting horizons through shape-wise feature engineering.

description: Belle data for the pi-pi mass spectrum in X(3872) -> pi-pi + JPsi are well fitted by rho + J/Psi with JPC = 1++, but are poorly fitted by the pi-pi S-wave. Formulae for partial wave amplitudes are given for all likely JPC and decay modes of the 3941 MeV peak in omega + J/Psi. Angular correlations involving up to five angles may allow a spin-parity determination, even with quite low statistics. Special attention is given to the case where X(3872) is a cusp or quasi-bound state with the same quantum numbers as the 3941 MeV peak.

description: En este trabajo se comparan las industrias agroalimentarias andaluza y valenciana con la espanola en 1995 utilizando tecnicas input-output. Tras revisar la literatura sobre interdependencia sectorial, antes de abordar su analisis empirico se examina la especializacion productiva, obteniendo algunas diferencias, aunque en ambos casos destacan los sectores tradicionales e intensivos en trabajo. El estudio de las ligazones directas entre las ramas permite no solo realizar una tipologia sectorial, sino tambien identificar las actividades que muestran miveles de desarrollo difrenciado, lo que podria servir como guia para mejorar el comportamiento de algunos sectores. las ligazones totales se han examindado mediante un nuevo modelo que combina aspectos de demanda y oferta, dada la complementariedad de ambas perspectivas. Su aplicacion a las tablas input-output de 1995 muestra el elevado potencial cuantitativo del sector agroindustrial, tanto para impulsar como, especialmente, captar el crecimiento...This paper compares the agro-food industries of Andalucia and Valencia with their Spanish counterparts in 1995 using input-output techniques. Before the empirical analysis, we review the literature concerning inter-sectoral relations and also show the structure of production in these economies. Although this analysis reveals some differences between the regions, in both of them prevail labor-intensive industries. In the input-output framework, the study of direct interdependences between sectors allows us to typify the industries and also identify the more advanced sectors. Total linkages are examined using a new input-output model that combines factors of supply and demand, showing the high relevance of agro-food industries to promote and, especially, to attract economic growth.

description: Single-atom metal alloy catalysts (SAACs) have recently become a very active new frontier in catalysis research. The simultaneous optimization of both facile dissociation of reactants and a balanced strength of intermediates' binding make them highly efficient and selective for many industrially important reactions. However, discovery of new SAACs is hindered by the lack of fast yet reliable prediction of the catalytic properties of the sheer number of candidate materials. In this work, we address this problem by applying a compressed-sensing data-analytics approach parameterized with density-functional inputs. Our approach is faster and more accurate than the current state-of-the-art linear relationships. Besides consistently predicting high efficiency of the experimentally studied Pd/Cu, Pt/Cu, Pd/Ag, Pt/Au, Pd/Au, Pt/Ni, Au/Ru, and Ni/Zn SAACs (the first metal is the dispersed component), we identify more than two hundred yet unreported candidates. Some of these new candidates are predicted to exhibit even higher stability and efficiency than the reported ones. Our study demonstrates the importance of breaking linear relationships to avoid bias in catalysis design, as well as provides a recipe for selecting best candidate materials from hundreds of thousands of transition-metal SAACs for various applications.
Inflationary Quantum Cosmology: General Framework and Exact Bianchi I Solution

description: Using the methods of loop quantum gravity, we derive a framework for describing an inflationary, homogeneous universe in a purely quantum theory. The classical model is formulated in terms of the Ashtekar-Sen connection variables for a general subclass of Bianchi class A spacetimes. This formulation then provides a means to develop a corresponding quantum theory. An exact solution is derived for the classical Bianchi type I model and the corresponding semi-classical quantum state is found to also be an exact solution to the quantum theory. The development of a normalizable quantum state from this exact solution is presented and the implications for the normalizability of the Kodama state discussed. We briefly consider some consequences of such a quantum cosmological framework and show that the quantum scale factor of the universe has a continuous spectrum in this model. This result may suggest further modifications that are required to build a more accurate theory. We close this study by suggesting a variety of directions in which to take the results presented.

title: Systematic review of candidate prognostic factors for falling in older adults identified from motion analysis of challenging walking tasks

description: The objective of this systematic review is to identify motion analysis parameters measured during challenging walking tasks which can predict fall risk in the older population. Numerous studies have attempted to predict fall risk from the motion analysis of standing balance or steady walking. However, most falls do not occur during steady gait but occur due to challenging centre of mass displacements or environmental hazards resulting in slipping, tripping or falls on stairs. We conducted a systematic review of motion analysis parameters during stair climbing, perturbed walking and obstacle crossing, predictive of fall risk in healthy older adults. We searched the databases of Pubmed, Scopus and IEEEexplore. A total of 78 articles were included, of which 62 simply compared a group of younger to a group of older adults. Importantly, the differences found between younger and older adults did not match those found between older adults at higher and lower risk of falls. Two prospective and six retrospective fall history studies were included. The other eight studies compared two groups of older adults with higher or lower risk based on mental or physical performance, functional decline, unsteadiness complaints or task performance. A wide range of parameters were reported, including outcomes related to success, timing, foot and step, centre of mass, force plates, dynamic stability, joints and segments. Due to the large variety in parameter assessment methods, a meta-analysis was not possible. Despite the range of parameters assessed, only a few candidate prognostic factors could be identified: older adults with a retrospective fall history demonstrated a significant larger step length variability, larger step time variability, and prolonged anticipatory postural adjustments in obstacle crossing compared to older adults without a fall history. Older adults who fell during a tripping perturbation had a larger angular momentum than those who did not fall. Lastly, in an obstacle course, reduced gait flexibility (i.e., change in stepping pattern relative to unobstructed walking) was a prognostic factor for falling in daily life. We provided recommendations for future fall risk assessment in terms of study design. In conclusion, studies comparing older to younger adults cannot be used to explore relationships between fall risk and motion analysis parameters. Even when comparing two older adult populations, it is necessary to measure fall history to identify fall risk prognostic factors.
