description: We bring together two popular formalisms which generically parameterise deviations from General Relativity on astrophysical and cosmological scales, namely the parameterised post-Newtonian (PPN) formalism and the effective field theory (EFT) of dark energy and modified gravity. These separate formalisms are successfully applied to independently perform tests of gravity in their respective regimes of applicability on vastly different length scales. Nonlinear screening mechanisms indeed make it imperative to probe General Relativity across a wide range of scales. For a comprehensive interpretation of the complementary measurements it is important to connect them to effectively constrain the vast gravitational model space. We establish such a connection within the framework of Horndeski scalar-tensor theories restricted to a luminal propagation speed of gravitational waves. This is possible via the reconstruction of the family of linearly degenerate covariant Horndeski actions from the set of EFT functions and the subsequent derivation of the PPN parameters from the reconstructed theory. We outline the required conditions which ensure a reconstructed Horndeski model possesses a screening mechanism that enables significant modifications on cosmological scales while respecting stringent astrophysical bounds. Employing a scaling method, we then perform the general post-Newtonian expansion of the reconstructed models to derive their PPN parameters $γ$ and $β$ in their screened regimes.

Classification of multi-channel EMGs for jaw motion recognition by signal processing and artificial neural networks
Creators: name: Fu, Bin
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents an EMG pattern recognition method to identify jaw movements. Pattern recognition is carried out using backpropagation artificial neural networks (BPN) trained by supervised learning. Different feature extraction methods have been implemented. Results are presented to support the feasibility of the suggested approach. Electromyography (EMG) is electrical activity of muscle. Bruxism is the involuntary and excessive clenching and grinding of teeth. It is one of the reasons that cause serious teeth damage and jaw muscle disorder and currently there is no definitive cure. Knowing actual jaw actions during bruxism will help in designing a more targeted treatment mode. EMG provides information about the neuromuscular activity from which it originates. When performing different muscle contractions, different EMGs are detected. Different muscle contractions are related to various movement tasks. Therefore it is possible to process the EMG to obtain movement classification. The purpose of this study is to design an algorithm to detect jaw motion (simulated bruxism) from the EMG signals. The process consists of feeding the EMG signals to a feature extraction block; and then the extracted features are supplied to an artificial neural network (ANN). The ANN classifies the motion into six categories: left, right and forward with two speeds, fast and slow. The application of this algorithm can provide the basis for a clinical evaluation of bruxism. In this study, three feature extraction techniques have been implemented for comparative analysis: EMG linear envelope (LE), autoregressive modelling (AR parameter estimation) and a hybrid approach of the AR model and discrete wavelet transform (DWT). The performance of the three methods has been evaluated. The ANN structure consists another part of the study. While both linear envelope method and AR model method were able to classify the direction of jaw movement, each confused with the fast and slow speed at the same direction to some extent. To solve the problem, a new ANN structure was designed for the linear envelope method by adding more features like the duration and the integral information of the waveform These features work as bias to the ANN structure and they not only yield high correct classification rates but also strengthen the robustness of the ANN. Finally the classification performance of the algorithm was checked in 10 healthy subjects and reasonable results were obtained. These were best with downsampled LE with the ANN (structure III).

description: In order to investigate the origin of the far-UV (FUV) flux from the early-type galaxies, Galaxy Evolution Explorer (GALEX) is collecting the UV data for the elliptical-rich clusters at moderate redshifts (z < 0.2) where the dominant FUV source is predicted to be hot horizontal-branch (HB) stars and their post-HB progeny. Here we present our first result for the early-type galaxies in Abell 2670 at z = 0.076. Compared to NGC 1399, a nearby giant elliptical galaxy in the Fornax cluster, it appears that the rest-frame FUV - V color of the giant ellipticals gets redder by ~ 0.7 mag at the distance of Abell 2670 (z = 0.076; look-back time ~ 1.0 Gyr). Although a detailed comparison with the models is postponed until more cluster data are accumulated, it is interesting to note that this value is consistent with the variation predicted by the population synthesis models where the mean temperature of HB stars declines rapidly with increasing look-back time.

description: Purpose: To demonstrate the feasibility and performance of a fully automated deep learning framework to estimate myocardial strain from short-axis cardiac magnetic resonance tagged images. Methods and Materials: In this retrospective cross-sectional study, 4508 cases from the UK Biobank were split randomly into 3244 training and 812 validation cases, and 452 test cases. Ground truth myocardial landmarks were defined and tracked by manual initialization and correction of deformable image registration using previously validated software with five readers. The fully automatic framework consisted of 1) a convolutional neural network (CNN) for localization, and 2) a combination of a recurrent neural network (RNN) and a CNN to detect and track the myocardial landmarks through the image sequence for each slice. Radial and circumferential strain were then calculated from the motion of the landmarks and averaged on a slice basis. Results: Within the test set, myocardial end-systolic circumferential Green strain errors were -0.001 +/- 0.025, -0.001 +/- 0.021, and 0.004 +/- 0.035 in basal, mid, and apical slices respectively (mean +/- std. dev. of differences between predicted and manual strain). The framework reproduced significant reductions in circumferential strain in diabetics, hypertensives, and participants with previous heart attack. Typical processing time was ~260 frames (~13 slices) per second on an NVIDIA Tesla K40 with 12GB RAM, compared with 6-8 minutes per slice for the manual analysis. Conclusions: The fully automated RNNCNN framework for analysis of myocardial strain enabled unbiased strain evaluation in a high-throughput workflow, with similar ability to distinguish impairment due to diabetes, hypertension, and previous heart attack.

description: We identify a strong similarity among several distinct originally second-class systems, including both mechanical and field theory models, which can be naturally described in a gauge-invariant way. The canonical structure of such related systems is encoded into a gauge-invariant generalization of the quantum rigid rotor. We pursue the BRST symmetry analysis and the BFV functional quantization for the mentioned gauge-invariant version of the generalized quantum rigid rotor. We obtain different equivalent effective actions according to specific gauge-fixing choices, showing explicitly their BRST symmetries. We apply and exemplify the ideas discussed to two particular models, namely, motion along an elliptical path and the $O(N)$ nonlinear sigma model, showing that our results reproduce and connect previously unrelated known gauge-invariant systems.

Vision-based 3D motion tracking in natural environments
Creators: name: Saeedi, Parvaneh
Publisher: name: University of British Columbia
Year: 2009

description: Remotely controlled mobile robots have been a subject of interest for many years. They have a wide range of applications i n science and in industries such as aerospace, marine, forestry, construction and mining. A key requirement of such control is the full and precise knowledge of the location and motion of the mobile robot at each moment of time. This thesis presents a vision-based location tracking system suitable for autonomous vehicle navigation and guidance in unknown environments. The system includes a trinocular vision head that can be mounted anywhere on a navigating robot. Consecutive sets of triplet 2D images are used to determine the 3D location and the 3D motion parameters of the robot at each frame. By selecting only the most informative points of each image, using a feature detection algorithm, faster performance is achieved. The use of 3 cameras improves the accuracy and the robustness of the system. By tracking the 3D location of world features within a multi-stage tracking approach, the location of the observer camera is estimated and tracked over time. The motion with 6 DoF is found via a least squares minimization method. A Kalman filter implementation is used to optimize the 3D representation of scene features in order to improve the accuracy of the overall system. The system introduces several novel contributions for vision-based trajectory tracking. Firstly, it presents a new binary corner detector that can automatically detect the most informative and reliable scene feature points. This feature detector performs 60% faster than the most common method, the Harris corner detector, used in vision-based tracking applications. Secondly, it compensates for an inherent source of inaccuracy in the camera geometry. By identifying and matching features in raw images, and then unwarping matched data, accurate 3D world feature reconstruction is achieved. Thirdly, through a two-stage search and tracking design, similar 3D world feature points axe identified and tracked over time. This design, by itself, improves the accuracy of the estimated motions at each time by up to 10%. Finally, it improves the accuracy of the 3D trajectory tracking system with 6 degrees of freedom in natural environments. Results of the application of our method to the trajectory tracking problem in natural and unknown environments are reported to validate our approach, hypotheses and methods. The cumulative translational and rotational errors of the system are less than 1% for the studied examples.

description: We present a general method for the computation of tree-level superpotentials for the world-volume theory of B-type D-branes. This includes quiver gauge theories in the case that the D-brane is marginally stable. The technique involves analyzing the A-infinity structure inherent in the derived category of coherent sheaves. This effectively gives a practical method of computing correlation functions in holomorphic Chern-Simons theory. As an example, we give a more rigorous proof of previous results concerning 3-branes on certain singularities including conifolds. We also provide a new example.

description: Whereas roots of globalization are far reaching, it is primarily a modern age phenomenon. Modern business operation and the world economy are characterized by domination of multinational corporations, strong presence of the government in economy and the long-term tendency towards globalization in manufacturing, trading and consumption in the world. Containing both risks and opportunities, globalization is a problem of manifold nature. For some it means regression and falling into “neocolonialism”, the others glorify it. It is logical to ask the following questions: What are the consequences of globalization for governments, nations, companies and individuals? What are the business, social and ethical issues it causes? In one word, is it possible to be ethical, to avoid and correct “bad” and keep “good” consequences of total phenomena as the globalization, and whether it is rewarding in the increasing market competition?

We discuss that there are boundary degrees of freedom residing at the horizon. We describe their symmetries and their interactions with gravitational waves. This fits into a larger picture of boundary plus bulk degrees of freedom and their interactions in gauge theories. Existence and dynamics of the near horizon degrees of freedom could be crucial to address fundamental questions and apparent paradoxes in black holes physics.

description: ABSTRACT--Shariah regulations play a fundamental role in the governance of the Islamic banking industry. The Shariah board is an essential tool of the Shariah governance. This paper aims to investigate the efficacy of Shariah governance in Islamic banks in the evolving regulatory frameworks and sheds some light on the Islamic corporate governance. This study theoretically compares different Shariah governance structures, the centralized Shariah structure followed by Pakistan, Malaysia, Iran and the decentralized Shariah structure in Gulf Cooperation Council (GCC) countries. The Shariah board’s independence in its supervisory role is the main feature of an effective Shariah governance framework. In terms of the efficiency and credibility of Islamic banks, thecentralized Shariah structure seems to be more advantageous for the industry. The centralized Shariah structure ensures consistency and uniformity in Islamic banking in issuing the fatwas (Shariah opinions). It improves the Shariah board’s role and independence that can analyze divergence issues across the entire Shariah board. Thisstudy could be helpful to researchers, practitioners, regulators, and academicians in understanding the true picture of Shariah governance. This paper emphasizes the importance of investigating the Shariah governance in Islamic banking. The study gives a direction to empirically investigate the role of centralized and decentralized Shariahstructure on Islamic banks’ performance.

description: In the last decade of the 20th century knowledge has gained importance in the economy. This lead to the emergence of knowledge-based activities: knowledge-intensive organizations, and particularly knowledge-intensive services. These organizations function as external knowledge sources for other organizations. Their performance depends largely on professional knowledge. Since their performance has an impact on the success of their clients, it is important to look at those factors which influence the knowledge transfer between service provider and client organization. Based on theory and empirical research, the paper addresses the specific aspects of knowledge transfer from knowledge-intensive business service organizations to client organizations.

description: We perform the first direct determination of the position of the leading singularity of the pressure in the complex chemical potential $μ_B$ plane in lattice QCD using numerical simulations with 2-stout improved rooted staggered fermions. This provides a direct determination of the radius of convergence of the Taylor expansion of the pressure that does not rely on a finite-order truncation of the expansion. The analyticity issues in the complex $μ_B$ plane of the grand canonical partition function of QCD with rooted staggered fermions are solved with a careful redefinition of the fermion determinant that makes it a polynomial in the fugacity on any finite lattice, without changing the continuum limit of the observables. By performing a finite volume scaling study at a single coarse lattice spacing, we show that the limiting singularity is not on the real line in the thermodynamic limit, thus showing that the radius of convergence of the Taylor expansion gives a lower bound on the location of a possible phase transition. In the vicinity of the crossover temperature at zero chemical potential, the radius of convergence turns out to be $μ_B/T \approx 2$ and roughly temperature independent.

description: Cool pavements designate alternative pavements designed to reduce their contribution to urban heating. Urban heating generally refers to the sensible heat exchanged with the atmosphere by urban materials but can also include the radiative load they impose on pedestrians. In either case, pavement surface temperature is a very important parameter, which cool pavements seek to decrease compared with standard pavement designs. The energy balance of a pavement surface or very thin pavement slab helps identify the outbound flows which cool pavements attempt to promote and fundamental physical principles which govern them. On this basis, cool pavements can be classified as reflective pavements, green and evaporative pavements, high inertia or phase changing pavements as well as conductive or heatharvesting pavements. This chapter presents the urban heat island and the urban heating phenomena and provides an overview of cool pavement technologies, detailing areas which require further scientific investigation.

description: We review the definition of a quandle, and in particular of the core quandle $\mathrm{Core}(G)$ of a group $G$, which consists of the underlying set of $G$, with the binary operation $x\lhd y = x y^{-1} x$. This is an involutory quandle, i.e., satisfies the identity $x\lhd (x\lhd y) = y$ in addition to the other identities defining a quandle. Trajectories $(x_i)_{i\in\mathbb{Z}}$ in groups and in involutory quandles (in the former context, sequences of the form $x_i = x z^i$ where $x,z\in G,$ among other characterizations; in the latter, sequences satisfying $x_{i+1}= x_i\lhd\,x_{i-1})$ are examined. A family of necessary conditions for an involutory quandle to be embeddable in the core quandle of a group is noted. Some implications are established between identities holding in groups and in their core quandles. Upper and lower bounds are obtained on the number of elements needed to generate the quandle $\mathrm{Core}(G)$ for $G$ a finitely generated group. Several questions are posed.

In [1, 2], an ODD scheme was proposed based on the Chernoff bound on the pairwise error probability (PEP) for maximum-likelihood sequence estimation (MLSE) [3]. It was shown that the ODD scheme outperforms the generalized delay diversity (GDD) scheme proposed in [4] in frequency-selective fading channels. However, the MLSE scheme is too complex for most practical applications. Therefore, low-complexity equalization schemes such as decision-feedback equalization (DFE) [5] or even linear equalization (LE) [6] have to be used. In this work, two novel ODD schemes are investigated. The ODD transmit filters of the two novel schemes are optimized for correlated multiple-input multiple-output (MIMO) frequencyselective Rayleigh fading channels with suboptimum DFE or LE employed at the receiver, respectively. An equivalent discrete-time channel model containing the DD transmit filters, the pulse shaping filters, the mobile channel, and the receiver input filters is first given. Then, the worst-case pairwise error probabilities (PEPs) for both DFE and LE are derived based on the discretetime channel model and the error variances of the two schemes. Finally, a stochastic gradient algorithm for optimization of the ODD filter coefficients is proposed. The algorithm assumes knowledge of the channel impulse response (CIR) at the receiver while only the statistics of the CIRs are required at the transmitter. The proposed algorithm takes into account the equivalent discrete-time channel, the operating signal-to-noise ratio (SNR), the modulation scheme, the length of the ODD transmit filters as well as the correlations of the transmit and receive antennas. The resulting ODD filters are applied to GSM1 [7, 8] and EDGE2 [9, 10]. Simulation results show that the ODD filters obtained in this work achieve a lower bit error rate (BER) than those obtained in [1, 2, 4] when DFE and LE are used at the receiver, respectively. The results of this thesis have been summarized in [11, 12].

description: Development of infrastructure is essential presumption for growth and development of relevant economic entities. The empirical evidence of private initiative importance and potentials in the establishment of cooperation with the public sector in infrastructure projects financing and operation refocused professional and academic attention on the studies of this phenomenon. The realm of the public private partnership (PPP) became scientifically treated as an interdisciplinary skill based mostly on project financing, whilst practically it became almost mandatory method for economic prosperity. Practical problems in implementation appeared due to lack of knowledge and nonsystematic approach in researches of private public partnership. This paper presents theoretical and practical directions for actors in this cooperation, scoping for mobilization of assets and energy for development and facilitation, and advancing of project investments efficiency.

description: Quantum Speed Limits (QSLs) rule the minimum time for a quantum state to evolve into a distinguishable state in an arbitrary physical process. These fundamental results constrain a notion of distance travelled by the quantum state, known as the Bures angle, in terms of the speed of evolution set by nonadiabatic energy fluctuations. We theoretically propose how to measure QSLs in an ultracold quantum gas confined in a time-dependent harmonic trap. In this highly-dimensional system of continuous variables, quantum tomography is prohibited. Yet, QSLs can be probed whenever the dynamics is self-similar by measuring as a function of time the cloud size of the ultracold gas. This makes possible to determine the Bures angle and energy fluctuations, as we discuss for various ultracold atomic systems.

description: To ease the difficulty of acquiring annotation labels in 3D data, a common method is using unsupervised and open-vocabulary semantic segmentation, which leverage 2D CLIP semantic knowledge. In this paper, unlike previous research that ignores the ``noise'' raised during feature projection from 2D to 3D, we propose a novel distillation learning framework named CUS3D. In our approach, an object-level denosing projection module is designed to screen out the ``noise'' and ensure more accurate 3D feature. Based on the obtained features, a multimodal distillation learning module is designed to align the 3D feature with CLIP semantic feature space with object-centered constrains to achieve advanced unsupervised semantic segmentation. We conduct comprehensive experiments in both unsupervised and open-vocabulary segmentation, and the results consistently showcase the superiority of our model in achieving advanced unsupervised segmentation results and its effectiveness in open-vocabulary segmentation.

description: We revisit the computation (hep-th/0306130) of 1-loop AdS_5 x S^5 superstring sigma model correction to energy of a closed circular string rotating in S^5. The string is spinning around its center of mass with two equal angular momenta J_2=J_3 and its center of mass angular momentum is J_1. We revise the argument in hep-th/0306130 that the 1-loop correction is suppressed by 1/J factor (J= J_1 + 2 J_2 is the total SO(6) spin) relative to the classical term in the energy and use numerical methods to compute the leading 1-loop coefficient. The corresponding gauge theory result is known (hep-th/0405055) only in the J_1=0 limit when the string solution becomes unstable and thus the 1-loop shift of the energy formally contains an imaginary part. While the comparison with gauge theory may not be well-defined in this case, our numerical string theory value of the 1-loop coefficient seems to disagree with the gauge theory one. A plausible explanation should be (as in hep-th/0405001) in the different order of limits taken on the gauge theory and the string theory sides of the AdS/CFT duality.

description: We study the double Compton (DC) process for a wide range of particle energies, extending previous treatments well beyond the soft photon limit, employing both numerical and analytical methods. This allows us to investigate the physics of the DC process up to the highly relativistic regime relevant to electromagnetic particle cascades in the early Universe and photon-dominated astrophysical plasmas. Generalized exact analytic expressions for the DC emissivity in the soft photon limit are obtained. These are compared to existing approximations, for the first time studying the ultra-relativistic regime. We also numerically integrate the full DC collision term calculating the DC emissivity at general particle energies. A careful treatment of DC infrared divergences inside astrophysical plasmas, including subtle effects related to the presence of stimulated DC emission, is discussed. The obtained results can be efficiently represented using the code DCpack, which also allows one to compute average emissivities for general incoming electron and photon distributions. This puts the modelling of the DC process inside astrophysical plasmas on a solid footing and should find applications in particular for computations of the cosmological thermalization problem in the early Universe.

description: Despite numerous appeals, since the beginning 1987, to diversify the economy of Russia, the aim is not achieved. The article argues that the diversification as a process lacks adequate institutional conditioning. Path-dependency provided stability to economic growth while the structure of economy remains mainly unchanged. Global financial crisis gives an opportunity to stir up discussion on diversification as driving factor of innovative development. The author believes that methodology and theory of constructing sustained and diversified productions is mechanically imported from foreign sources, regardless institutional realities of Russian market. Considering all this, the paper suggests creating institutional framework capable to manage processes of economy diversification.
Non-Markovian effect on quantum Otto engine: -Role of system--reservoir interaction-

description: We study a limit cycle of a quantum Otto engine whose each cycle consists of two finite-time quantum isochoric (heating or cooling) processes and two quantum adiabatic work-extracting processes. Considering a two-level system as a working substance that weakly interacts with two reservoirs comprising an infinite number of bosons, we investigate the non-Markovian effect (short-time behavior of the reduced dynamics in the quantum isochoric processes (QIPs)) on work extraction after infinite repetition of the cycles. We focus on the parameter region where energy transferred to the reservoir can come back to the system in a short-time regime, which we call energy backflow to show partial quantum-mechanical reversibility. As a situation completely different from macroscopic thermodynamics, we find that the interaction energy is finite and negative by evaluating the average energy change of the reservoir during the QIPs by means of the full-counting statistics, corresponding to the two-point measurements. The feature leads us to the following findings: (1) the Carnot theorem is consistent with a definition of work including the interaction energy, although the commonly used definition of work excluding the interaction leads to a serious conflict with the thermodynamic law, and (2) the energy backflow can increase the work extraction. Our findings show that we need to pay attention to the interaction energy in designing a quantum Otto engine operated in a finite time, which requires us to include the non-Markovian effect, even when the system-reservoir interaction is weak.
