A quantitative assessment of bone and cartilage morphology at the glenohumeral joint in manual wheelchair users
Creators: name: LaFrance, Amy Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: Debilitating shoulder pain is prevalent among wheelchair users, however the causes remain unknown. Shoulder pain is reported to be greater among those who began wheeling after skeletal maturity (adulthood-onset, AO) than among those who began wheeling prior to skeletal maturity (childhood-onset, CO). It is unclear whether functional load-bearing from manual wheelchair use affects glenohumeral bone and cartilage morphology. Bone is known to adapt to loading, however the literature is conflicting regarding cartilage’s capacity to adapt to loading. We performed a pilot study to quantify bone and cartilage morphology at the glenohumeral joint of manual wheelchair users (nco=3, nao=5) and age- and gender-matched able-bodied controls (nc=8). Bone morphology (volumetric bone mineral density (vBMD) and normalized cross-sectional area (nCSA)) was evaluated using quantitative computed tomography. Bone density distribution was assessed across the glenoid and, for the first time, across the humeral head using a novel quantitative CT-Osteoabsorptiometry method. Cartilage morphology (thickness, volume, and surface area) was evaluated using quantitative magnetic resonance imaging, in the first assessment at 3T MRI. This novel combination of methods provides complementary quantitative data of glenohumeral bone and cartilage morphology. Compared to the AO, the CO in our study had significantly higher (p<0.05) glenoid subchondral nCSA, non-significantly lower glenoid subchondral vBMD, and non-significantly higher humeral head and glenoid trabecular vBMD. A reasonable cross-sectional study (n=22) would likely show higher humeral head and glenoid trabecular vBMD and glenoid subchondral nCSA in CO subjects but would not find differences in nCSA of humeral head total, trabecular, and cortical bone, or glenoid trabecular bone. Surprisingly, vBMD was (non-significantly) lower in the wheelchair users than in the able-bodied controls, however activity levels varied considerably. Significant correlations were found between humeral head and glenoid trabecular vBMD (r=0.94), and between humeral head trabecular vBMD and physical activity scores (r= 0.84). Given the small effect sizes and the large variance in humeral head and glenoid cartilage thickness, volume, and surface area, it is not likely that further study of these parameters would provide insight into wheelchair users’ shoulder pain. Gaining a better understanding of how glenohumeral bone and cartilage respond to wheelchair use would allow for rehabilitation programs and wheelchair-design to be tailored to childhood-onset and adulthood-onset wheelchair users.

description: Due to the proliferation of malware, defenders are increasingly turning to automation and machine learning as part of the malware detection tool-chain. However, machine learning models are susceptible to adversarial attacks, requiring the testing of model and product robustness. Meanwhile, attackers also seek to automate malware generation and evasion of antivirus systems, and defenders try to gain insight into their methods. This work proposes a new algorithm that combines Malware Evasion and Model Extraction (MEME) attacks. MEME uses model-based reinforcement learning to adversarially modify Windows executable binary samples while simultaneously training a surrogate model with a high agreement with the target model to evade. To evaluate this method, we compare it with two state-of-the-art attacks in adversarial malware creation, using three well-known published models and one antivirus product as targets. Results show that MEME outperforms the state-of-the-art methods in terms of evasion capabilities in almost all cases, producing evasive malware with an evasion rate in the range of 32-73%. It also produces surrogate models with a prediction label agreement with the respective target models between 97-99%. The surrogate could be used to fine-tune and improve the evasion rate in the future.

description: We introduce a two-dimensional growth model where every new site is located, at a distance $r$ from the barycenter of the pre-existing graph, according to the probability law $1/r^{2+α_G} (α_G \ge 0)$, and is attached to (only) one pre-existing site with a probability $\propto k_i/r^{α_A}_i (α_A \ge 0$; $k_i$ is the number of links of the $i^{th}$ site of the pre-existing graph, and $r_i$ its distance to the new site). Then we numerically determine that the probability distribution for a site to have $k$ links is asymptotically given, for all values of $α_G$, by $P(k) \propto e_q^{-k/κ}$, where $e_q^x \equiv [1+(1-q)x]^{1/(1-q)}$ is the function naturally emerging within nonextensive statistical mechanics. The entropic index is numerically given (at least for $α_A$ not too large) by $q = 1+(1/3) e^{-0.526 α_A}$, and the characteristic number of links by $κ\simeq 0.1+0.08 α_A$. The $α_A=0$ particular case belongs to the same universality class to which the Barabasi-Albert model belongs. In addition to this, we have numerically studied the rate at which the average number of links $$ increases with the scaled time $t/i$; asymptotically, $ \propto (t/i)^β$, the exponent being close to $β={1/2}(1-α_A)$ for $0 \le α_A \le 1$, and zero otherwise. The present results reinforce the conjecture that the microscopic dynamics of nonextensive systems typically build (for instance, in Gibbs $Γ$-space for Hamiltonian systems) a scale-free network.

description: In recent years there has been a dynamic growth in the share of private labels in the market. Survey which was carried out by direct questionnaire among the Tri-City consumers shows that these products enjoy growing reputation and are more popular. Respondents point to the low price of the product and good quality. The barriers are accessibility of markets and bad placement of products on the shelves. The most popular private labels are these offered by Biedronka, Lidl and Tesco. Private labels are an alternative for the development of small domestic companies, promotion of local producers and products

description: The concept of crowdsourced measurements allows service providers to outsource the expensive and time consuming task of performance measurements to the end user device. This approach is obviously appealing for the industry, though giving up the control on the experiment in favor. In this thesis we took a first step into the analysis of crowdsourced data sets in order to build up a view of the current status of the network. This work aims at answering the question whether it is possible to use crowdsourced data to meaningfully characterize properties of the network. The thesis i) introduces theoretical concepts for systematic description and processing of data rate series based on data volume samples; ii) describes implementation of generic framework allowing for repeated measurements and benchmarking various measurement tools; iii) analyzes results of controlled measurements produced by the same tools which are used for crowdsourced measuremnts; iv) analyzes results of crowdsourced measurements. Controlled measurements reveal great potential of crowdsourced open data, yielding positive answer to the stated question. The use of real data set collected by the regulatory body in Austria, RTR, proofed to be challenging due to multiple factors: The first element is the pollution of the data set by systematic events, e.g. operator tests at special locations, operator optimizations in user profiling and many more. The second element is the dynamic of the data set in temporal and spatial dimension. The analysis and the reference measurements reveal clear time of day effects, e.g. clear diurnal load cycles in the cells. Finally, current implementation of RTR data is recorded in a lossy fashion. The analysis shows that the information loss cannot be recovered. Therefore, limitations due to user tariffs and network dynamics cannot be precisely removed. However, this work shows that even considering all these effects it is possible to already use the data set to gather network performance benchmark figures.

description: We report an unexpected theoretical discovery of a spin one half matter field with mass dimension one. It is based on a complete set of eigenspinors of the charge conjugation operator. Due to its unusual properties with respect to charge conjugation and parity it belongs to a non standard Wigner class. Consequently, the theory exhibits non-locality with (CPT)^2 = - I. Its dominant interaction with known forms of matter is via Higgs, and with gravity. This aspect leads us to contemplate it as a first-principle candidate for dark matter.

description: We use techniques for lower bounds on communication to derive necessary conditions in terms of detector efficiency or amount of super-luminal communication for being able to reproduce with classical local hidden-variable theories the quantum correlations occurring in EPR-type experiments in the presence of noise. We apply our method to an example involving n parties sharing a GHZ-type state on which they carry out measurements and show that for local-hidden variable theories, the amount of super-luminal classical communication c and the detector efficiency eta are constrained by eta 2^(-c/n) = O(n^(-1/6)) even for constant general error probability epsilon = O(1).

description: Production Planning and Control Systems aim to achieve an optimum of efficiency and flexibility in all processes to cope with the requirements a modern production faces. Events that lead to deviations from actual production to planned are considered to have negative consequences on the achievement of operational objectives. To manage the probability and severity of such turbulences, a system can be optimized regard its resilience. Resilience is the capability of a system to avoid and endure a disturbance as long as possible and recover quickly afterwards. The goal of this master´s thesis is to develop a framework for the integration of resilience into traditional production planning and control systems. The framework has to guide the reader thru the theoretical context of production planning and control systems, risk and resilience management, control systems as well as the creation and integration of resilience in an existing system. The methodology applied to create such a framework is design science research. After the identification of the research problem and the motivation to solve such, the objectives of a solution are defined. The design and development of an artifact that is applicable to solve the research problem is the main contribution to current research knowledge. By applying the methodology of design science research, a framework for the integration of resilience into a traditional production planning and control system was designed, created and demonstrated. The objectives and requirements for such a framework and the concluding characteristics of a system after applying it are met as defined in the scope and problem statement.

description: This letter presents a two-dimensional nuclear magnetic resonance(NMR) approach for constructing a two-logical-qubit decoherence-free subspace (DFS) based on the fact that the three protons in a CH3 spin system can not be resolved in one-dimension NMR spectroscopy, but to a certain extent, can be distinguished by two-dimensional multiple-quantum NMR. We used four noisy physical nuclear spins, including three protons and one carbon in the CH3 spin system, to generate two decoherence-free logical quantum bits. It made full use of the unaddressed spins which could not be used in one-dimensional spectrum. Furthermore, we have experimentally demonstrated such an approach. Our experimental results have shown that our DFS can protect against far more types of decoherence than the one composed of four noisy physical qubits all with different chemical shifts. More importantly, this idea may provide new insights into extending qubit systems in the sense that it effectively utilizes the magnetically equivalent nuclei.

description: Background: The nuclear symmetry energy $E_{sym}(ρ)$ encodes information about the energy necessary to make nuclear systems more neutron-rich. While its slope parameter L at the saturation density $ρ_0$ of nuclear matter has been relatively well constrained by recent astrophysical observations and terrestrial nuclear experiments, its curvature $K_{\rm{sym}}$ characterizing the $E_{sym}(ρ)$ around $2ρ_0$ remains largely unconstrained. Over 520 calculations for $E_{sym}(ρ)$ using various nuclear theories and interactions in the literature have predicted several significantly different $K_{\rm{sym}}-L$ correlations. Purpose: If a unique $K_{\rm{sym}}-L$ correlation of $E_{sym}(ρ)$ can be firmly established, it will enable us to progressively better constrain the high-density behavior of $E_{sym}(ρ)$ using the available constraints on its slope parameter L. We investigate if and by how much the different $K_{\rm{sym}}-L$ correlations may affect neutron star observables. Method: A meta-model of nuclear Equation of States (EOSs) with three representative $K_{\rm{sym}}-L$ correlation functions is used to generate multiple EOSs for neutron stars. We then examine effects of the $K_{\rm{sym}}-L$ correlation on the crust-core transition density and pressure as well as the radius and tidal deformation of canonical neutron stars. Results:The $K_{\rm{sym}}-L$ correlation affects significantly both the crust-core transition density and pressure. It also has strong imprints on the radius and tidal deformability of canonical neutron stars especially at small L values. The available data from LIGO/VIRGO and NICER set some useful limits for the slope L but can not distinguish the three representative $K_{\rm{sym}}-L$ correlations considered.

description: We consider wormhole geometries subject to a gravitational action consisting of non-linear powers of the Ricci scalar. Specifically, wormhole throats are studied in the case where Einstein gravity is supplemented with a Ricci-squared and inverse Ricci term. In this modified theory it is found that static wormhole throats respecting the weak energy condition can exist. The analysis is done locally in the vicinity of the throat, which eliminates certain restrictions on the models introduced by considering the global topology.

description: The recent deep generative models for static graphs that are now being actively developed have achieved significant success in areas such as molecule design. However, many real-world problems involve temporal graphs whose topology and attribute values evolve dynamically over time, including important applications such as protein folding, human mobility networks, and social network growth. As yet, deep generative models for temporal graphs are not yet well understood and existing techniques for static graphs are not adequate for temporal graphs since they cannot 1) encode and decode continuously-varying graph topology chronologically, 2) enforce validity via temporal constraints, or 3) ensure efficiency for information-lossless temporal resolution. To address these challenges, we propose a new model, called ``Temporal Graph Generative Adversarial Network'' (TG-GAN) for continuous-time temporal graph generation, by modeling the deep generative process for truncated temporal random walks and their compositions. Specifically, we first propose a novel temporal graph generator that jointly model truncated edge sequences, time budgets, and node attributes, with novel activation functions that enforce temporal validity constraints under recurrent architecture. In addition, a new temporal graph discriminator is proposed, which combines time and node encoding operations over a recurrent architecture to distinguish the generated sequences from the real ones sampled by a newly-developed truncated temporal random walk sampler. Extensive experiments on both synthetic and real-world datasets demonstrate TG-GAN significantly outperforms the comparison methods in efficiency and effectiveness.

description: The performance of a company is usually dependent on numerous external and internal factors. In this master’s thesis the focus was centered around the influence of the company’s size and its age on the financial performance of a corporation. More specifically, food and beverage restaurant franchises were examined for their efficiency and profitability potential. The United States was appointed as geographical focus of this research, considering the importance of the franchise sector which is expected to outperform the growth of the national GDP this year again, generating about USD 710 billion output in 2017 and contributing to the job creation with approximately 7.888.500 employments. Out of the 744.437 franchise establishments in the United States, about 30% belong to the food and beverage restaurant sector. The analysis conducted was originally undertaken for 56 food and beverage franchise quoted on the American stock exchange. Through the help of the data envelopment analysis method, the study has revealed the most efficient franchises, which include amongst others Dominos’s Pizza, the Bravo Brio Restaurant Group, Dunkin Brands Group, McDonalds and Bojangles Chicken. The most profitable companies comprise of Yum Brands!, Freshii, Papa John’s International, McDonalds and Popeys’ Louisiana Kitchen. The subsequent linear regression analysis has been undertaken to analyze the relationship between age / size and the newly obtained relative efficiency scores and profitability percentage. The results revealed a significant positive relationship between the size of the company and profitability. A non-significant but positive relationship was concluded on in the case of efficiency and company size as well as efficiency and firm age. The correlation between age and profitability was on the other hand non-significantly negative. Thus these results call for future research on the food and beverage restaurant franchises in the United States.

description: The noetic end-to-end response selection challenge as one track in the 7th Dialog System Technology Challenges (DSTC7) aims to push the state of the art of utterance classification for real world goal-oriented dialog systems, for which participants need to select the correct next utterances from a set of candidates for the multi-turn context. This paper presents our systems that are ranked top 1 on both datasets under this challenge, one focused and small (Advising) and the other more diverse and large (Ubuntu). Previous state-of-the-art models use hierarchy-based (utterance-level and token-level) neural networks to explicitly model the interactions among different turns' utterances for context modeling. In this paper, we investigate a sequential matching model based only on chain sequence for multi-turn response selection. Our results demonstrate that the potentials of sequential matching approaches have not yet been fully exploited in the past for multi-turn response selection. In addition to ranking top 1 in the challenge, the proposed model outperforms all previous models, including state-of-the-art hierarchy-based models, on two large-scale public multi-turn response selection benchmark datasets.

description: The filamentous cyanobacterium Nostoc puntiforme ATCC 29133 is a promising strain for sustainable production of different compounds. The aim of this thesis is to investigate the native light-inducible promoter PcpeC as a tool for future biotechnological approaches. For this work the expression levels of different genes of Synechocystis sp. PCC 6803 and Clamydomonas reinhardtii under the regulation of PcpeC were analyzed. The genes were fused to fluorescence protein YFP or GFP to quantify the protein amount by determination of fluorescence. Three N. punctiforme strains containing the different constructs were tested under different green light conditions for induction, and under red light as repressing conditions. The results showed that there are different expression levels as well as different growth behavior of the tested strains. Furthermore, we were able to show that PcpeC in N. punctiforme ATCC 29133 is regulated by different intensities of green light and that this promoter is completely repressed by red light. Thus indicating its usefulness as a tool to regulate expression of recombinant proteins in cyanobacteria.

description: It has been an interesting question that why there are one-third of Kuiper Belt Objects (KBOs) trapped into the 3:2 resonance but, in contrast, only several KBOs are claimed to be associated with the 2:1 resonance. In a model proposed by Zhou et al. (2002), the stochastic outward migration of the Neptune could reduce the number of particles in the 2:1 resonance and thus the objects in the 3:2 resonance become more distinct. As a complementary study, we investigate the effect of proto-stellar discs on the resonance capture. Our results show that the gaseous drag of a proto-stellar disc can trap KBOs into the 3:2 resonance rather easily. In addition, no objects are captured into the 2:1 resonance in our simulation.

title: Effects of the implementation of the Austrian Energy Efficiency Act on electric utilities - recent experiences and adaptations in business models to address energy efficiency

description: The importance of taking energy efficiency measures for electric utilities has increased since the Energy Efficiency Directive (2012/27/EU) was issued. This thesis focuses on the implementation of the Austrian Energy Efficiency Act and on how its legal obligation has affected electric utilities after the second reporting period. It provides insights in their experiences and adaptations in business models to address energy efficiency. Primary data to answer both research questions were obtained through guided interviews based on Bortz and Döring (2014). The techniques of qualitative content analysis by Mayring (2014) were applied for the evaluation of the experts’ interviews. In total, six representatives of five electricity utilities, with energy sales of more than 45 GWh during the last year and with more than 249 employees, were interviewed. As a result, familiarity with procedures during the first reporting period allowed a smooth implementation of the second period’s reporting requirements. The measures by the household sector were basically the same as reported in the first year. According to the interviewees, the only economically viable and scalable business models are in the heating sector (gas thermal value equipment and heat pump). Overall, the interviewees strongly criticized the bureaucratic expenditure for reporting energy efficiency measures, in particular, as the energy efficiency measures taken at end customers by the energy suppliers do not necessarily lead to a decrease in the overall consumption of energy. In general, the interviewees see no challenges for their companies to report the obligated measures until 2020, but they are concerned about the framework that will be put in place for the years 2020 to 2030.

description: We present a method for constructing stationary, asymptotically flat, rotating solutions of Einstein's field equations. One of the spun-up solutions has quasilocal mass but no global mass. It has an ergosphere but no event horizon. The angular momentum is constant everywhere beyond the ergosphere. The energy-momentum content of this solution can be interpreted as a rotating string-fluid.

description: The paper elaborates on the characterization and assessment of the American experience in the use of commodity promotion to increase the efficiency of the producers and processors of pork and competitiveness of the sector and attempt to present recommendations for the pork meat sector in Poland. Competitiveness of the pork sector is determined, inter alia, by the joint actions of pork producers and processors in the range of generic promotional activities. For the assessment of the pork meat sector in Poland, currently surviving structural crisis it seems important to know the experiences of other countries in this regard. Experience commodity promotion programs in the U.S. have confirmed as their economic efficiency and to ensure the development of this sector and stabilize producers’ incomes

Mechanics and dynamics of drilling
Creators: name: Roukema, Jochem Christiaan
Publisher: name: University of British Columbia
Year: 2011

description: This thesis presents the mathematical modeling of drilling mechanics and dynamics in order to improve hole shape accuracy, optimize the drill tool geometry and drilling operations. The thesis presents prediction of cutting forces, torque, power, vibrations and hole shape as a function of drill edge geometry, work material dependent cutting coefficients, drill structure and drilling conditions. The forces and torque are expressed as a function of chip load distribution along the cutting edge and cutting force coefficients. As the drill rotates and thrusts into the material, it experiences torsional, lateral and axial vibrations. The coordinates of the cutting edges, which generate the cut surface, are predicted by applying cutting forces and torque on the drill's structural dynamic model. The generated surface is digitized, and the chip distribution along the flute is calculated by subtracting it from the surface generated by the previous flute. Hence, the exact model of drilling kinematics and structural dynamics are considered, which leads to integrated simulation of static, dynamic and regenerative chatter vibrations of the drilling process and generated hole surface. The model is also used to investigate the mechanism of whirling vibrations and the hole wall formation by imposing commonly observed whirling motion on the drill. The simulation shows good similarity with experimentally measured cutting forces and hole geometries. Although it is computationally costly, the numerical model of the drilling process considers the full physical model with true kinematics, dynamics and nonlinearities such as cutting coefficients and tool jumping out of cut due to excessive vibrations. As an alternative, an analytical frequency domain stability analysis for drilling is proposed for efficient generation of stability charts. The stability lobes predicted by the numerical and linear frequency domain models agreed well. Although the models agreed well with the experimental results published in the literature, a significant discrepancy is observed at practical drilling speeds where the high frequency modes of the drill led to chatter. It is shown that the unmodeled rubbing of the drill's flank with the wavy surface finish and chisel edge contact, i.e. process damping, remains a fundamental challenge in further research.

description: Galactic nuclei showing recurrent phases of activity and quiescence have recently been discovered, with recurrence times as short as a few hours to a day -- known as quasi-periodic X-ray eruption (QPE) sources -- to as long as hundreds to a thousand days for repeating nuclear transients (RNTs). Here we present a multi-wavelength overview of Swift J023017.0+283603 (hereafter Swift J0230+28), a source that exhibits repeating and quasi-periodic X-ray flares from the nucleus of a previously unremarkable galaxy at $\sim$ 165 Mpc, with a recurrence time of approximately 22 days, an intermediary timescale between known RNTs and QPE sources. The source also shows transient radio emission, likely associated with the X-ray emission. Such recurrent soft X-ray eruptions, with no accompanying UV/optical emission, are strikingly similar to QPE sources. However, in addition to having a recurrence time that is $\sim 25$ times longer than the longest-known QPE source, Swift J0230+28's eruptions exhibit somewhat distinct shapes and temperature evolution than the known QPE sources. Scenarios involving extreme mass ratio inspirals are favored over disk instability models. The source reveals an unexplored timescale for repeating extragalactic transients and highlights the need for a wide-field, time-domain X-ray mission to explore the parameter space of recurring X-ray transients.

How transverse thermal fluctuations disorder a condensate of chiral spirals into a quantum spin liquid

description: For a scalar theory with a global $O(N)$ symmetry, when $N=2$ a spatially inhomogeneous condensate arises when the term in the Lagrangian with two spatial derivatives has a negative coefficient. If the condensate for such a chiral spiral includes only one mode, characterized by a momentum $k_0 \hat{z}$, then in perturbation theory at nonzero temperature the propagator for the static mode has a double pole when $\vec{k}^2 = k_0^2$. We conjecture that since chiral spirals spontaneously break both global and spacetime symmetries, that such double poles are a universal property of their static transverse modes. Fluctuations from double poles generate linear infrared divergences in any number of spatial dimensions and disorder the condensate of chiral spirals, analogous to a type of quantum spin liquid. The characteristic feature of this region is that over large spatial distances the two point function is the usual exponential times an oscillatory function. We prove this at large $N$ and suggest this occurs for all $N > 2$. Implications for four-fermion models and the phase diagram of QCD are discussed.
