description: We present broad band optical afterglow observations of a long duration GRB 060124 using the 1.04-m Sampurnanand Telescope at ARIES, Nainital and the 2.01-m HCT at IAO, Hanle, including the earliest ground based observations in R band for this GRB. We determine the decay slope of the light curve at different bands and examine the reality of a proposed jet break. We use data from our observations as well as others reported in the literature to construct light curves in different bands and make power law fits to them. The spectral slope of the afterglow emission in the optical band is estimated. Our first R-band observations were taken $\sim 0.038$~d after burst. We find that all available optical data after this epoch are well fit by a single power law, with a temporal flux decay index $α\sim 0.94$. We do not find any evidence of a jet break within our data, which extend till $\sim 2$~d after the burst. The X-ray light curve, however, shows a distinct break around 0.6 day. We attribute this break to a steepening of the electron energy spectrum at high energies. We conclude that the above measurements are consistent with the picture of a standard fireball evolution with no jet break within $t\sim 2$~days after the burst. This sets a lower limit of $3\times 10^{50}$~erg to the total energy released in the explosion.

description: This artifact contains all information of the results reported and needed for replication. Machine Learning Based Invariant Generation: A Framework and Reproducibility Study Abstract—Software verification is the task of proving correct-
 ness of programs against specified requirements. Key to software
 verification is the automatic generation of loop invariants. In
 recent years, template- and logic-based approaches to invariant
 generation have been complemented by machine learning (ML)
 techniques. A number of proposals for such techniques exist
 today. Although all authors perform experimental evaluations
 of their proposals, comparability of the core techniques is nev-
 ertheless hindered by differing benchmarks, specific tunings of
 hyperparameters, missing public availability as well as specialized
 preprocessings and runtime environments.
 In this paper, we present the modular framework MIGML
 for experimentation with and comparison of ML invariant
 generators. MIGML contains the core ingredients of ML based
 invariant generators (i.e. a teacher and a learner) as instantiable
 components with clear-cut interfaces. This conceptually novel
 framework allows for a reproducibility study of four existing
 ML invariant generators: we re-implement the teacher and
 learner components of the four techniques within our framework
 which permits a comparison on equal grounds. We are able
 to successfully reproduce and partially confirm the reported
 results. We furthermore experiment with novel combinations of
 components, e.g. employ the data generator within the teacher
 of technique A together with the learner of technique B. As a
 result, we observe that such combinations can lead to an overall
 enhanced effectiveness. A minimal version is also published.

description: Measurements of the static magnetic susceptibility and of the nuclear magnetic resonance of multiwalled vanadium-oxide nanotubes are reported. In this nanoscale magnet the structural low-dimensionality and mixed valency of vanadium ions yield a complex temperature dependence of the static magnetization and the nuclear relaxation rates. Analysis of the different contributions to the magnetism allows to identify individual interlayer magnetic sites as well as strongly antiferromagnetically coupled vanadium spins (S = 1/2) in the double layers of the nanotube's wall. In particular, the data give strong indications that in the structurally well-defined vanadium-spin chains in the walls, owing to an inhomogeneous charge distribution, antiferromagnetic dimers and trimers occur. Altogether, about 30% of the vanadium ions are coupled in dimers, exhibiting a spin gap of the order of 700 K, the other ~ 30% comprise individual spins and trimers, whereas the remaining \~ 40% are nonmagnetic.

description: We present a simple scheme to implement the Deutsch-Jozsa algorithm based on two-atom interaction in a thermal cavity. The photon-number-dependent parts in the evolution operator are canceled with the strong resonant classical field added. As a result, our scheme is immune to thermal field, and does not require the cavity to remain in the vacuum state throughout the procedure. Besides, large detuning between the atoms and the cavity is not necessary neither, leading to potential speed up of quantum operation. Finally, we show by numerical simulation that the proposed scheme is equal to demonstrate the Deutsch-Jozsa algorithm with high fidelity.

Structural influences on reduction potential, electron transfer and stability in cytochrome c
Creators: name: Lo, Terence Pui-Kwan
Publisher: name: University of British Columbia
Year: 2009

description: The work described in this thesis was directed toward understanding the contributions of Phe82, Leu85 and associated residues to the structure and function of cytochrome c. One focus of these studies concerned the roles of these residues at the interactive face formed during electron transfer reactions involving cytochrome c and its redox partners. Phe82 was found to make an important contribution to this process, while the adjacent Leu85 does not have a significant impact. However, both residues indirectly affect complex formation by influencing the placement of the side chain of Arg13. In related studies, Leu85 was found to contribute to the formation of the heme binding pocket as a participant in a cluster of conserved leucine residues. This leucine cluster, as well as an adjacent internal hydrophobic cavity, were shown to provide a measure of conformational flexibility when mutations are made in cytochrome c and may facilitate the structural transition of this protein between oxidation states. It was also determined that replacement of Leu94, which is also a member of this leucine cluster, did not alter the helix-helix interactions of the N- and C-terminal helices of cytochrome c as had been suggested by earlier studies. Also apparent from further studies was the important functional role played by Phe82 in the regulation of heme reduction potential which could be attributed to its contribution to the nonpolar environment of the heme pocket. Related to this, it was found that the effects of polar groups on reduction potential were mitigated when these groups were shielded from the heme macrocycle by intervening heme substituents. An additional factor in the regulation of reduction potential was characterized as part of the study of Phe82 and distal residues involved in interactions with heme propionate A. Here it was shown that the mechanisms by which Arg38 and Asn52 influence reduction potential differ from that of Phe82. Furthermore, for Arg38 and Asn52, these effects overlap and synergistic effects are observed when they are replaced in concert. In contrast, the structural implications of either single or multiple substitutions at Arg38, Asn52 and Phe82 were determined to be independent as was the impact on structural stability as a whole. Overall it is clear from these studies that Phe82, Leu85, and likely many other residues in cytochrome c, have multiple structural and functional roles and that the interplay between the roles of these residues are correspondingly complex and difficult to predict.

description: Transformer has become the new standard method in natural language processing (NLP), and it also attracts research interests in computer vision area. In this paper we investigate the application of Transformer in Image Quality (TRIQ) assessment. Following the original Transformer encoder employed in Vision Transformer (ViT), we propose an architecture of using a shallow Transformer encoder on the top of a feature map extracted by convolution neural networks (CNN). Adaptive positional embedding is employed in the Transformer encoder to handle images with arbitrary resolutions. Different settings of Transformer architectures have been investigated on publicly available image quality databases. We have found that the proposed TRIQ architecture achieves outstanding performance. The implementation of TRIQ is published on Github (https://github.com/junyongyou/triq).

description: Fine-Grained Visual Categorization (FGVC) is a challenging topic in computer vision. It is a problem characterized by large intra-class differences and subtle inter-class differences. In this paper, we tackle this problem in a weakly supervised manner, where neural network models are getting fed with additional data using a data augmentation technique through a visual attention mechanism. We perform domain adaptive knowledge transfer via fine-tuning on our base network model. We perform our experiment on six challenging and commonly used FGVC datasets, and we show competitive improvement on accuracies by using attention-aware data augmentation techniques with features derived from deep learning model InceptionV3, pre-trained on large scale datasets. Our method outperforms competitor methods on multiple FGVC datasets and showed competitive results on other datasets. Experimental studies show that transfer learning from large scale datasets can be utilized effectively with visual attention based data augmentation, which can obtain state-of-the-art results on several FGVC datasets. We present a comprehensive analysis of our experiments. Our method achieves state-of-the-art results in multiple fine-grained classification datasets including challenging CUB200-2011 bird, Flowers-102, and FGVC-Aircrafts datasets.

description: Software systems play an ever more important role in our lives and software engineers and their companies find themselves in a position where they are held responsible for ethical issues that may arise. In this paper, we try to disentangle ethical considerations that can be performed at the level of the software engineer from those that belong in the wider domain of business ethics. The handling of ethical problems that fall into the responsibility of the engineer have traditionally been addressed by the publication of Codes of Ethics and Conduct. We argue that these Codes are barely able to provide normative orientation in software development. The main contribution of this paper is, thus, to analyze the normative features of Codes of Ethics in software engineering and to explicate how their value-based approach might prevent their usefulness from a normative perspective. Codes of Conduct cannot replace ethical deliberation because they do not and cannot offer guidance because of their underdetermined nature. This lack of orientation, we argue, triggers reactive behavior such as "cherry-picking", "risk of indifference", "ex-post orientation" and the "desire to rely on gut feeling". In the light of this, we propose to implement ethical deliberation within software development teams as a way out.

description: Thanks to the excellent learning capability of deep convolutional neural networks (CNN), monocular depth estimation using CNNs has achieved great success in recent years. However, depth estimation from a monocular image alone is essentially an ill-posed problem, and thus, it seems that this approach would have inherent vulnerabilities. To reveal this limitation, we propose a method of adversarial patch attack on monocular depth estimation. More specifically, we generate artificial patterns (adversarial patches) that can fool the target methods into estimating an incorrect depth for the regions where the patterns are placed. Our method can be implemented in the real world by physically placing the printed patterns in real scenes. We also analyze the behavior of monocular depth estimation under attacks by visualizing the activation levels of the intermediate layers and the regions potentially affected by the adversarial attack.

description: We consider the problem of pulsed biexciton preparation in a quantum dot and show that a pulse-sequence with a simple on-off-on modulation can achieve complete preparation of the target state faster than the commonly used constant and hyperbolic secant pulses. The durations of the pulses composing the sequence are obtained from the solution of a transcendental equation. Furthermore, using numerical optimal control, we demonstrate that for a wide range of values of the maximum pulse amplitude, the proposed pulse-sequence prepares the biexciton state in the numerically obtained minimum time, for the specific system under consideration. We finally show with numerical simulations that, even in the presence of dissipation and dephasing, high levels of biexciton state fidelity can be generated in short times.

description: Recommender systems play a crucial role in helping users to find their interested information in various web services such as Amazon, YouTube, and Google News. Various recommender systems, ranging from neighborhood-based, association-rule-based, matrix-factorization-based, to deep learning based, have been developed and deployed in industry. Among them, deep learning based recommender systems become increasingly popular due to their superior performance. In this work, we conduct the first systematic study on data poisoning attacks to deep learning based recommender systems. An attacker's goal is to manipulate a recommender system such that the attacker-chosen target items are recommended to many users. To achieve this goal, our attack injects fake users with carefully crafted ratings to a recommender system. Specifically, we formulate our attack as an optimization problem, such that the injected ratings would maximize the number of normal users to whom the target items are recommended. However, it is challenging to solve the optimization problem because it is a non-convex integer programming problem. To address the challenge, we develop multiple techniques to approximately solve the optimization problem. Our experimental results on three real-world datasets, including small and large datasets, show that our attack is effective and outperforms existing attacks. Moreover, we attempt to detect fake users via statistical analysis of the rating patterns of normal and fake users. Our results show that our attack is still effective and outperforms existing attacks even if such a detector is deployed.

description: Atomic force microscopy-based nanoindentation (AFM-NI) enables characterization of the basic mechanical properties of wood pulp fibers in conditions representative of the state inside a paper sheet. Determination of the mechanical properties under different loads is critical for the success of increasingly advanced computational models to understand, predict and improve the behavior of paper and paperboard. Here, AFM-NI was used to indent fibers transverse to and along the longitudinal axis of the fiber. Indentation moduli and hardness were obtained for relative humidity from 25 % to 75 %. The hardness and the indentation modulus exhibit moisture dependency, decreasing by 75 % and 50 %, respectively, over the range tested. The determined indentation moduli were combined with previous work to estimate the longitudinal and transverse elastic modulus of the fiber wall. Due to the relatively low indentation moduli, the elastic constants are also low compared to values obtained via single fiber testing.

Looking at the emerging, effective description of the apparatus given by the action of a coarse-graining channel, we have been able to recover information about the superposition coefficients of the system.We have also been able to visualize the death of quantum correlations between system and apparatus and the death of quantum coherences in the apparatus' effective state, in the limit of a strong coarse-graining action - a situation akin to decoherence, although it is not necessary to evoke any interaction with the surrounding environment.

description: Η παρούσα διπλωματική εργασία εξετάζει τις προοπτικές ανάπτυξης των ελληνικών τραπεζών στην περιοχή της χερσονήσου του Αίμου και της Νοτιοανατολικής Ευρώπης. Αρχικά, γίνεται μια αναφορά σχετικά με την παρουσία των ελληνικών επιχειρήσεων στη Βαλκανική χερσόνησο και στη Νοτιοανατολική Ευρώπη αναφέροντας τους λόγους για τους οποίους επένδυσαν και εξακολουθούν να επενδύουν οι Έλληνες επιχειρηματίες εκεί, καθώς και τις ευκαιρίες που υπάρχουν, αλλά και τους κινδύνους που εγκυμονούν οι εκεί επενδύσεις. Υπάρχουν αναφορές σχετικά με τη θεωρία της διαμεσολάβησης, με τη δομή και ολοκλήρωση του ευρωπαϊκού τραπεζικού συστήματος καθώς και ανάλυση της οικονομίας κάθε χώρας της Νοτιοανατολικής Ευρώπης και των Βαλκανίων. Η έρευνα συνεχίζει με την ανάλυση του νομικού πλαισίου που διέπει τις συγχωνεύσεις και τις εξαγορές καθώς και τους λόγους για τους οποίους ευδοκιμούν ή μη τέτοιες ενέργειες στον τραπεζικό κλάδο. Ολοκληρώνοντας, το πρακτικό μέρος της εργασίας επικεντρώθηκε στην ανάλυση των οικονομικών καταστάσεων για τη διετία 2008 και 2009 και μέσω αριθμοδεικτών επιδιώχθηκε να εξαχθούν συμπεράσματα ως προς την πορεία τριών ελληνικών χρηματοπιστωτικών ιδρυμάτων (Ε.Τ.Ε, Alpha Bank, Τράπεζα Πειραιώς) στις αγορές αυτές. Αποδεικνύεται, λοιπόν, ότι οι τράπεζες αυτές έχουν ισχυρή παρουσία στο χώρο των Βαλκανίων και της Νοτιοανατολικής Ευρώπης και παρουσιάζουν ανοδική πορεία καθώς εξαπλώνονται συνεχώς, τόσο αυξάνοντας το μερίδιο αγοράς τους όσο και παρέχοντας καινοτόμες τραπεζικές υπηρεσίες.
description: This diplomatic work examines the development prospects of Greek banks in the Peninsula area of' Balkan and the South-Eastern Europe. Initially, is a reference on the presence of Greek undertakings in the Balkan peninsula and in the Southeastern Europe indicating the reasons for the reasons why they have invested and continue to invest the Greek operators there, and the opportunities which exist, but also the risks posed by investments there. There are reports on the theory of mediation, with the structure and completion of the European banking system and analysis of the economy each country of South East Europe and the Balkans. The investigation continues with the analysis of the legal framework governing mergers and acquisitions, and the reasons why they thrive or non-such actions in the banking sector. In conclusion, the practical part of the work has focused on analysis of financial statements for the two years 2008 and 2009 and through indicators sought to draw conclusions as to the progress made three Greek financial institutions ( N.B.G, Alpha Bank, Piraeus Bank) in these markets. It is proved, therefore, that these banks have a strong presence in the Balkan area and south-east Europe and presenting upward trend as spreads continuously, both by increasing their market share as well as providing innovative banking services.

description: $(π^-,K^+)$ hyperon production inclusive spectra with $p_π=1.2$ GeV/c measured at KEK on $^{12}$C and $^{28}$Si are analyzed by the semiclassical distorted wave model. Single-particle wave functions of the target nucleus are treated using Wigner transformation. This method is able to account for the energy and angular dependences of the elementary process in nuclear medium without introducing the factorization approximation frequently employed. Calculations of the $(π^+,K^+)$ $Λ$ formation process, for which there is no free parameter since the $Λ$ s.p. potential is known, demonstrate that the present model is useful to describe inclusive spectra. It is shown that in order to account for the experimental data of the $Σ^-$ formation spectra a repulsive $Σ$-nucleus potential is necessary whose magnitude is not so strong as around 100 MeV previously suggested.

Relaxation mechanism for electron spin in the impurity band of n-doped semiconductors

description: We propose a mechanism to describe spin relaxation in n-doped III-V semiconductors close to the Mott metal-insulator transition. Taking into account the spin-orbit interaction induced spin admixture in the hydrogenic donor states, we build a tight-binding model for the spin-dependent impurity band. Since the hopping amplitudes with spin flip are considerably smaller than the spin conserving counterparts, the resulting spin lifetime is very large. We estimate the spin lifetime from the diffusive accumulation of spin rotations associated with the electron hopping. Our result is larger but of the same order of magnitude than the experimental value. Therefore the proposed mechanism has to be included when describing spin relaxation in the impurity band.

Ut pictura poesis: Keats, anamorphosis, and Taoism
Creators: name: Li, Richard W.
Publisher: name: University of British Columbia
Year: 2009

description: The present dissertation proposes a fresh approach to Keats's remarkable growth and development as a poet by assessing his works in relation to four different but interrelated contexts: the tradition of poetry as a "speaking picture," Lacanian interpretations of that tradition, the related nature of classical Chinese poetry, and parallels between Keatsian themes and Taoist principles. Chapter one seeks to assess Keats's poetry by articulating the relationship between "ut pictura poesis" on the one hand, and psychoanalysis and Taoist philosophy on the other. Chapter two deals with the invisible ground of the sympathetic imagination. Chapter three discusses Keats's philosophy of "negative capability" with reference to the Taoist philosophy of the "Middle Path." Chapter four compares Keats's Lamia to the Chinese legend The White Snake. Chapter five concludes the work by showing how the poet matures into "poethood" through an anamorphotic process of developing from the imaginary to the symbolic. The focus of this dissertation is on the pictorial and sculptural qualities of Keats's poetry in comparison with many poems in the Chinese and western traditions. Efforts have also been made to combine psychoanalytical theory and Taoist philosophy and poetics to shed light on the discussion. Even though the dissertation seeks to assess Keats's poetry through an analogy with the plastic arts and to extend this assessment through conceptual categories provided by psychoanalysis (with reference to the poet's maturing into "poethood") and Taoist philosophy (with reference to the poet's philosophy of "negative capability"), it does not assert that Keats is a psychoanalyst nor does it claim that he is a Taoist. Keats is mainly a poet dealing with human emotion, love, beauty, truth, and imagination — a poet with "no self," a poet who can be regarded as "the perfect man" (Tao Te Chinq, 18) in the truest sense of a Taoist.
Quasi-one-dimensional disordered systems: fluctuations, transport and interplay

description: In a one dimensional lattice thermal fluctuations destroy the long-range order making particles of the lattice move on a scale much larger than the lattice spacing. We discuss the assumption that this motion may be responsible for the transport of localized electrons in a system of weakly coupled chains. The model with diffusing localization sites gives a temperature-independent mobility with a crossover to an activated dependence at high temperature. This prediction is consistent with and might account for experimental results on discotic liquid crystals and certain biopolymers.

description: (Abridged) The strong lensing models of galaxy clusters rely on the number and quality of multiple images with spectroscopic redshifts. We present an updated strong lensing model of MACS J0416.1-2403 with the largest sample of multiple images with spectroscopic redshifts in a galaxy cluster field to date. Furthermore, we aim to demonstrate the effectiveness of JWST, particularly its NIRISS camera, for strong lensing studies. We used NIRCam imaging and NIRSpec and NIRISS spectroscopy from the CAnadian NIRISS Unbiased Cluster Survey (CANUCS). The cluster mass model was constrained using Lenstool software. Our new dataset, which we used for constraining the lens model, comprises 303 secure multiple images with spectroscopic redshifts from 111 background sources and includes 95 systems with previously known MUSE redshift and 16 systems (with 46 multiple images) for which we obtained spectroscopic redshift for the first time using NIRISS and NIRSpec spectroscopy. Three of the spectroscopic systems were not identified by previous JWST studies. The total number of secure spectroscopic systems is more than 20% higher than in the previous strong lensing studies of this cluster. The model can reproduce multiple images with the root-mean-square distance of ~ 0.52''. We also provide a full catalogue with 415 multiple images, including less reliable candidates. In total, we provide 15 new multiple-image system candidates (with 38 multiple images) not reported in previous studies. Furthermore, we demonstrate the effectiveness of JWST, particularly NIRISS, for obtaining spectroscopic redshifts of multiple images. As NIRISS F115W, F150W, and F200W grism spectroscopy captures at least two of the [OII], [OIII] and H$α$ lines at 1 < z < 3 (a redshift range particularly relevant for strong lensing studies) without target pre-selection, it complements MUSE and NIRSpec observations extremely well.

A Deep Learning Algorithm for Fault Imbalance Diagnostics in Wind Turbine Rotors Using Electrical Generator Signals
Creators: name: Franchi:, C.M.
Publisher: name: Zenodo
Year: 2019

description: This work attempts to answer the following research question: can fault imbalance diagnostics in wind turbine rotors using electrical generator signals be improved with deep learning methods? For this purpose, a framework using TurbSim/FAST/Simulink was developed to simulate electric signals generated from a 1.5 MW WT for different wind inflow scenarios and blade imbalances parameters. The simulations were used to train, validate and test a deep learning algorithm, and the fault classification metrics were
 obtained. It is possible to detect amplitude and frequency modulation from the current spectrum due to the imbalance, which spread the harmonics components in sidebands around its nominal frequency.
