Solid state NMR connectivity experiments involving quadrupolar nuclei
Creators: name: Wong-Moon, Kirby Charles
Publisher: name: University of British Columbia
Year: 2009

description: This thesis describes double-resonance solid-state NMR connectivity experiments involving quadrupolar and spin-1/2 nuclei. Cross-polarization, transferred-echo double-resonance (TEDOR), rotational-echo double-resonance (REDOR), and dipolar-dephasing difference experiments were used to determine connectivities via the heteronuclear dipolar-couplings between quadrupolar and spin-1/2 nuclei. Two-dimensional extensions of the cross-polarization and TEDOR experiments reveal connectivities between specific resonances in two-dimensional correlation spectra. Cross-polarization experiments were performed between 27Al and 31P nuclei in the aluminophosphate molecular sieves VPI-5 and AIPO4-8, and an experimental investigation of the parameters controlling the efficiency of the transfer is presented. REDOR, TEDOR, and dipolar-dephasing difference experiments are also demonstrated. Increased efficiency in cross-polarization experiments involving quadrupolar nuclei is obtained between 27Al and 31P spins in VPI-5 by carrying out the cross-polarization step with the spinning axis parallel to the applied magnetic field. After the cross-polarization step, the spinning axis is rapidly switched to the "magic angle" for detection of the high-resolution signal. The experiments developed for 27Al and 31P nuclei were extended to 27Al and 29Si nuclei for a series of representative zeolite frameworks, in which there is a relative enhancement of a given Si resonance which is approximately linear with the number of aluminum atoms in the neighbouring tetrahedral sites. Further extensions of the techniques to include 11B, 23Na, and 29Si nuclei are demonstrated for borosilicate glasses. The 27Al/ 31P and 27Al/29 Si connectivity experiments were used to determine the method of silicon substitution and reveal the presence of three types of aluminum environments in the sihcoaluminophosphate molecular sieve SAPO-37. The experiments. were also applied to the aluminophosphate AIPO4-5, confirming that the octahedral aluminum formed upon hydration remains bonded in the framework. For the first time, INEPT and DEPT experiments were performed in the solidstate. These experiments utilize coherence-transfer based on heteronuclear J-couplings to detect through-bond connectivities. Examples presented show that the experiments are applicable to both quadrupolar and spin-1/2 nuclei, and that only the +1/2 energy levels of the quadrupolar nuclei are involved in the coherence transfer.
Genetic code on the dyadic plane

description: We introduce the simple parametrization for the space of codons (triples of nucleotides) by 8\times 8 table. This table (which we call the dyadic plane) possesses the natural 2-adic ultrametric. We show that after this parametrization the genetic code will be a locally constant map of the simple form. The local constancy of this map will describe degeneracy of the genetic code. The map of the genetic code defines 2-adic ultrametric on the space of amino acids. We show that hydrophobic amino acids will be clustered in two balls with respect to this ultrametric. Therefore the introduced parametrization of space of codons exhibits the hidden regularity of the genetic code.

description: Neuromorphic processors like Loihi offer a promising alternative to conventional computing modules for endowing constrained systems like micro air vehicles (MAVs) with robust, efficient and autonomous skills such as take-off and landing, obstacle avoidance, and pursuit. However, a major challenge for using such processors on robotic platforms is the reality gap between simulation and the real world. In this study, we present for the very first time a fully embedded application of the Loihi neuromorphic chip prototype in a flying robot. A spiking neural network (SNN) was evolved to compute the thrust command based on the divergence of the ventral optic flow field to perform autonomous landing. Evolution was performed in a Python-based simulator using the PySNN library. The resulting network architecture consists of only 35 neurons distributed among 3 layers. Quantitative analysis between simulation and Loihi reveals a root-mean-square error of the thrust setpoint as low as 0.005 g, along with a 99.8% matching of the spike sequences in the hidden layer, and 99.7% in the output layer. The proposed approach successfully bridges the reality gap, offering important insights for future neuromorphic applications in robotics.

We show that a high-precision proton bunch time-tagging detector could turn a circular particle accelerator facility into a GW observatory sensitive to millihertz (mHz) GWs. We comment on sources of noise and the technological feasibility of ultrafast single photon detectors by conducting a case study of the Large Hadron Collider (LHC) at CERN.

description: Self-regularized low-light image enhancement does not require any normal-light image in training, thereby freeing from the chains on paired or unpaired low-/normal-images. However, existing methods suffer color deviation and fail to generalize to various lighting conditions. This paper presents a novel self-regularized method based on Retinex, which, inspired by HSV, preserves all colors (Hue, Saturation) and only integrates Retinex theory into brightness (Value). We build a reflectance estimation network by restricting the consistency of reflectances embedded in both the original and a novel random disturbed form of the brightness of the same scene. The generated reflectance, which is assumed to be irrelevant of illumination by Retinex, is treated as enhanced brightness. Our method is efficient as a low-light image is decoupled into two subspaces, color and brightness, for better preservation and enhancement. Extensive experiments demonstrate that our method outperforms multiple state-of-the-art algorithms qualitatively and quantitatively and adapts to more lighting conditions.

description: Current models for the folding of the human genome see a hierarchy stretching down from chromosome territories, through A/B compartments and TADs (topologically-associating domains), to contact domains stabilized by cohesin and CTCF. However, molecular mechanisms underlying this folding, and the way folding affects transcriptional activity, remain obscure. Here we review physical principles driving proteins bound to long polymers into clusters surrounded by loops, and present a parsimonious yet comprehensive model for the way the organization determines function. We argue that clusters of active RNA polymerases and their transcription factors are major architectural features; then, contact domains, TADs, and compartments just reflect one or more loops and clusters. We suggest tethering a gene close to a cluster containing appropriate factors -- a transcription factory -- increases the firing frequency, and offer solutions to many current puzzles concerning the actions of enhancers, super-enhancers, boundaries, and eQTLs (expression quantitative trait loci). As a result, the activity of any gene is directly influenced by the activity of other transcription units around it in 3D space, and this is supported by Brownian-dynamics simulations of transcription factors binding to cognate sites on long polymers.

description: Let $q$ be an odd prime, $m$ a positive integer, and let $\Ga_m(q)$ be the group generated by two elements $x$ and $y$ subject to the relations $x^{2m}=y^{qm}=1$ and $x^2=y^q$; that is, $\Ga_m(q)$ is the free product of two cyclic groups of orders $2m$ respectively $qm$, amalgamated along their subgroups of order $m$. Our main result determines the parity behaviour of the generalized subgroup numbers of $\Ga_m(q)$ which were defined in [T. W. Müller, Adv. in Math. 153 (2000), 118-154], and which count all the homomorphisms of index $n$ subgroups of $\Ga_m(q)$ into a given finite group $H$, in the case when $\gcd(m,| H|)=1$. This computation depends upon the solution of three counting problems in the Hecke group $\mathfrak H(q)=C_2*C_q$: (i) determination of the parity of the subgroup numbers of $\mathfrak H(q)$; (ii) determination of the parity of the number of index $n$ subgroups of $\mathfrak H(q)$ which are isomorphic to a free product of copies of $C_2$ and of $C_\infty$; (iii) determination of the parity of the number of index $n$ subgroups in $\mathfrak H(q)$ which are isomorphic to a free product of copies of $C_q$. The first problem has already been solved in [T. W. Müller, in: {\it Groups: Topological, Combinatorial and Arithmetic Aspects}, (T. W. Müller ed.), LMS Lecture Notes Series 311, Cambridge University Press, Cambridge, 2004, pp. 327-374]. The bulk of our paper deals with the solution of Problems (ii) and (iii).

description: In recent years there has been a big debate regarding the ways in which the different educational systems in the world could develop more inclusive practices in their schools. Based on the idea that the education of children considered as having special needs should be considered as a part of a wider process of school development in this study we will try to investigate the implications of the integration of deaf and hard-of-hearing students in rela¬tion to the practices used by teachers. Using qualitative data from a school in Cyprus we form two assertions which are substantiated with examples that include inclusive practices. The integration of deaf and hard-of-hearing students led teachers to the development of more inclusive practices which had an impact on all students of the school.

description: We report a neutron scattering study of the spin excitation spectrum in the superconducting state of slightly overdoped Bi2Sr2CaCu2O8+d system (Tc=87 K). We focus on the dispersion of the resonance peak in the superconducting state that is due to a S=1 collective mode. The measured spin excitation spectrum bears a strong similarity to the spectrum of the YBa2Cu3O6+x system for a similar doping level i.e. x= 0.95-1), which consists of intersecting upward- and downward-dispersing branches. A close comparison of the threshold of the electron-hole spin flip continuum, deduced from angle resolved photo-emission measurements in the same system, indicates that the magnetic response in the superconducting state is confined, in both energy and momentum, below the gapped Stoner continuum. In contrast to YBa2Cu3O6+x, the spin excitation spectrum is broader than the experimental resolution. In the framework of an itinerant-electron model, we quantitatively relate this intrinsic energy width to the superconducting gap distribution observed in scanning tunnelling microscopy experiments. Our study further suggests a significant in-plane anisotropy of the magnetic response.

description: In this master thesis, the issue of the identification of the actual dynamic characteristics of a construction through a suitable instrumentation form is studied. Initially, a literature review on the most important methods of the identification of dynamic characteristics of structures is presented as well as their categorization depending on their major advantages. Subsequently, the “method of modal time-histories” is described and is applied into a series of planar and spatial oscillators using simulated data with appropriate software (SAP2000) for the valuation of the method with respect to the oscillators’ eigen frequencies, modal shapes and modal damping ratios. Then, the thesis describes the instrumentation form of a steel scale with a suitable system of two accelerometers. The evaluation of the scale’s dynamic characteristics is accomplished through processing of the produced records due to ambient vibration. A finite element model of the steel scale is developed and the results of the simulation as well as the suitability of the “method of modal time-histories” are valuated.

description: The first step towards a society that respects and cares for its cultural heritage is formal and informal education that starts from early childhood. This kind of education is provided not only by museums that offer educa¬tional services addressed to schools and families, but depends highly on teacher attitudes and competence to deal with heritage issues and the learn¬ing potentials offered by museums and historical sites. This paper presents efforts made so far in Greece for the education of teachers of elementary, primary and high schools, on this subject, during their initial training in the Universities or in in-service seminars provided mostly by museums and museum organizations.

description: Online suicide games are claimed to involve a series of challenges, ending in suicide. A whole succession of these such as the Blue Whale Challenge, Momo, the Fire Fairy and Doki Doki have appeared in recent years. The challenge culture is a deeply rooted online phenomenon, whether the challenge is dangerous or not, while social media particularly motivates youngsters to take part because of their desire for attention. Although there is no evidence that the suicide games are real, authorities around the world have reacted by releasing warnings and creating information campaigns to warn youngsters and parents. We interviewed teachers, child protection experts and NGOs, conducted a systematic review of historical news reports from 2015-2019 and searched police and other authority websites to identify relevant warning releases. We then synthesized the existing knowledge on the suicide games phenomenon. A key finding of our work is that media, social media and warning releases by authorities are mainly just serving to spread the challenge culture and exaggerate fears regarding online risk.

description: A general stochastic traffic cellular automaton (CA) model, which includes slow-to-start effect and driver's perspective, is proposed in this paper. It is shown that this model includes well known traffic CA models such as Nagel-Schreckenberg model, Quick-Start model, and Slow-to-Start model as specific cases. Fundamental diagrams of this new model clearly show metastable states around the critical density even when stochastic effect is present. We also obtain analytic expressions of the phase transition curve in phase diagrams by using approximate flow-density relations at boundaries. These phase transition curves are in excellent agreement with numerical results.

description: Graphene has two atoms per unit cell with quasiparticles exhibiting the Dirac-like behavior. These properties lead to interband in addition to intraband optical transitions and modify the $f$-sum rule on the longitudinal conductivity. The expected dependence of the corresponding spectral weight on the applied gate voltage $V_g$ in a field effect graphene transistor is $\sim {const}- |V_g|^{3/2}$. For $V_g =0$, its temperature dependence is $T^3$ rather than the usual $T^2$. For the Hall conductivity, the corresponding spectral weight is determined by the Hall frequency $ω_H$ which is linear in the carrier imbalance density $ρ$, and hence proportional to $V_g$, and is different from the cyclotron frequency for Dirac quasiparticles.

We identify a structure, common to all maps consisting of a simple kernel perturbed by diffraction effects. This "essential" baker's map has a different semiclassical limit and can be diagonalized analytically for Hilbert spaces spanned by qubits. In all cases this kernel provides an accurate approximation to the spectral properties - eigenvalues and eigenfunctions - of all the different quantizations.

Broilers nowadays reach slaughter weight comparatively at a younger age and the embryonic period as well as the first week post-hatching represents 45 % of the whole life span. The first 14 post-hatch days represent approximately 25-33% of the growth period for broilers, 12.5% of the pullet development period in layers, and 10-14% of the life of a market turkey. Thus, pre-hatch as well as the transitional post-hatch period must be achieved efficiently. It is known that body weight is increased three to four-fold during the first week and considerable changes in gut, muscle weight and morphology are observed. Meat type broilers are capable of

description: With the prevailing of live video streaming, establishing an online pixelation method for privacy-sensitive objects is an urgency. Caused by the inaccurate detection of privacy-sensitive objects, simply migrating the tracking-by-detection structure into the online form will incur problems in target initialization, drifting, and over-pixelation. To cope with the inevitable but impacting detection issue, we propose a novel Privacy-sensitive Objects Pixelation (PsOP) framework for automatic personal privacy filtering during live video streaming. Leveraging pre-trained detection networks, our PsOP is extendable to any potential privacy-sensitive objects pixelation. Employing the embedding networks and the proposed Positioned Incremental Affinity Propagation (PIAP) clustering algorithm as the backbone, our PsOP unifies the pixelation of discriminating and indiscriminating pixelation objects through trajectories generation. In addition to the pixelation accuracy boosting, experiments on the streaming video data we built show that the proposed PsOP can significantly reduce the over-pixelation ratio in privacy-sensitive object pixelation.

Energy Band Engineering of Periodic Scatterers by Quasi-1D Confinement

description: A mechanism to modify the energy band structure is proposed by considering a chain of periodic scatterers forming a linear lattice around which an external cylindrical trapping potential is applied along the chain axis. When this trapping (confining) potential is tight enough, it may modify the bound and scattering states of the lattice potential, whose three-dimensional nature around each scattering center is fully taken into account and not resorting to zero-range pseudo-potentials. Since these states contribute to the formation of the energy bands, such bands could thereby be continuously tuned by manipulating the confinement without the need to change the lattice potential. In particular, such dimensionality reduction by quantum confinement can close band gaps either at the center or at the edge of the momentum k-space.

description: While the success of density functional theory (DFT) has led to its use in a wide variety of fields such as physics, chemistry, materials science and biochemistry, it has long been recognised that conventional methods are very inefficient for large complex systems, because the memory requirements scale as $N^2$ and the cpu requirements as $N^3$ (where $N$ is the number of atoms). The principles necessary to develop methods with linear scaling of the cpu and memory requirements with system size ($\mathcal{O}(N)$ methods) have been established for more than ten years, but only recently have practical codes showing this scaling for DFT started to appear. We report recent progress in the development of the \textsc{Conquest} code, which performs $\mathcal{O}(N)$ DFT calculations on parallel computers, and has a demonstrated ability to handle systems of over 10,000 atoms. The code can be run at different levels of precision, ranging from empirical tight-binding, through \textit{ab initio} tight-binding, to full \textit{ab initio}, and techniques for calculating ionic forces in a consistent way at all levels of precision will be presented. Illustrations are given of practical \textsc{Conquest} calculations in the strained Ge/Si(001) system.

As part of our model-based fitting methodology, we conducted an investigation into MARCS model atmospheres and found they systematically overestimate flux the cooler the star and bluer the wavelength. In addition, we developed an updated photometric [Fe/H] calibration with Gaia+2MASS photometry for isolated main sequence stars precise to ±0.19 dex. This was built upon a calibration sample of 69 cool dwarfs in binary systems with a hotter FGK companion, valid from super-solar to metal poor, and over 1.51 < Gaia BP‒RP < 3.3.

Oggetti fittizi, emozioni reali, seguite da una riflessione intorno ai temi trattati. Il paradosso della finzione (come è possibile provare emozioni reali per enti non esistenti nella realtà?) viene analizzato dal punto di vista dell’ontologia e di un ripensamento dell’investimento emotivo da parte del fruitore. La riflessione filosofica sulle opere artistiche è accompagnata da uno sguardo analitico sui prodotti di fruizione contemporanei, sulle modalità comunicative e sulcomplesso rapporto tra realtà e finzione.

description: We investigate the triplet-singlet relaxation in a double quantum dot defined by top-gates in an InAs nanowire. In the Pauli spin blockade regime, the leakage current can be mainly attributed to spin relaxation. While at weak and strong inter-dot coupling relaxation is dominated by two individual mechanisms, the relaxation is strongly reduced at intermediate coupling and finite magnetic field. In addition we observe a charateristic bistability of the spin-non conserving current as a function of magnetic field. We propose a model where these features are explained by the polarization of nuclear spins enabled by the interplay between hyperfine and spin-orbit mediated relaxation.

description: A larger portion of fake news quotes untampered images from other sources with ulterior motives rather than conducting image forgery. Such elaborate engraftments keep the inconsistency between images and text reports stealthy, thereby, palm off the spurious for the genuine. This paper proposes an architecture named News Image Steganography (NIS) to reveal the aforementioned inconsistency through image steganography based on GAN. Extractive summarization about a news image is generated based on its source texts, and a learned steganographic algorithm encodes and decodes the summarization of the image in a manner that approaches perceptual invisibility. Once an encoded image is quoted, its source summarization can be decoded and further presented as the ground truth to verify the quoting news. The pairwise encoder and decoder endow images of the capability to carry along their imperceptible summarization. Our NIS reveals the underlying inconsistency, thereby, according to our experiments and investigations, contributes to the identification accuracy of fake news that engrafts untampered images.

description: We elucidate the physics underlying ``anomaly mediation'', giving several alternative derivations of the formulas for gaugino and scalar masses. We stress that this phenomenon is of a type familiar in field theory, and does not represent an anomaly, nor does it depend on supersymmetry breaking and its mediation. Analogous phenomena are common in QFT and this particular phenomenon occurs also in supersymmetric theories without gravity.

description: We report the first experimental demonstration of an all-optical one-way implementation of Deutsch's quantum algorithm on a four-qubit cluster state. All the possible configurations of a balanced or constant function acting on a two-qubit register are realized within the measurement-based model for quantum computation. The experimental results are in excellent agreement with the theoretical model, therefore demonstrating the successful performance of the algorithm.

description: The purpose of this study was to explore similarities and differences in how practicing school psychologists conceptualized culturally responsive consultation across varying consultation paradigms. We conducted a secondary analysis of interviews of 15 school psychologists nationwide. Three major consultation paradigms emerged: (1) structured problem-solving with a medical model lens, (2) structured problem-solving with an ecological lens and, (3) ‘On-the-fly’ consultation with limited use of a problem-solving framework. The participants who described a medical model approach described their conceptualization of cultural variables in a broad manner, and they did not respond to cultural variables in robust ways. The participants who described an eco-behavioral approach to consultation actively incorporated culturally related variables throughout their consultation process. The participants who described an on-the-fly approach varied in their consideration of and response to cultural variables. Implications for research and practice are discussed.

Chomsky- Schützenberger Theorem

description: Το 1963 οι Chomsky και Schützenberger διατύπωσαν το ομώνυμο θεώρημα, το οποίο συνδέει τις γλώσσες χωρίς συμφραζόμενα με τις αναγνωρίσιμες γλώσσες και τις γλώσσες του Dyck. Τα τελευταία χρόνια η έρευνα έχει στραφεί σε αλγεβρικές γραμματικές με βάρη που επεκτείνουν την κλασσική θεωρία. Τα βάρη αυτά συνήθως θεωρούνταν στοιχεία ενός ημιδακτυλίου. Λόγω όμως της αδυναμίας των ημιδακτυλίων να περιγράψουν πράξεις όπως η μέση κατανάλωση πόρων, πρόσφατα οι Droste και Vogler θεώρησαν τα βάρη ως στοιχεία μιας γενικότερης αλγεβρικής δομής, του unital valuation monoid. Στην παρούσα εργασία, αφού ορίσουμε τις προαπαιτούμενες έννοιες, δίνουμε μια απόδειξη του κλασσικού θεωρήματος, κάνουμε μια περιγραφή των αλγεβρικών γραμματικών με βάρη από ένα unital valuation monoid και τέλος παρουσιάζουμε μια εκδοχή του παραπάνω θεωρήματος για τις γραμματικές αυτές.
description: In 1963, Chomsky and Schutzenberger proved the homonymous theorem, which connects context-free languages with recognizable languages and the languages of Dyck. Later, researchers focused on algebraic grammars with weights, in an attempt to extend the classical theory and provide a theoretical background for the applications. The weights were usually considered to be elements of a semiring. However, due to the inability of semirings to include operations, such as average consumption of resources, recently, Droste and Vogler considered taking weights from a more general algebraic structure, that of a unital valuation monoid. In this paper, after the definition of the prerequisite concepts, we give a proof of the classical theorem, we proceed to describe algebraic grammars with weights taken from a unital valuation monoid and, finally, we present a version of the above theorem for such grammars.
Reductionist approach to chemical rate constants using conditional energy probabilities

description: Different rate theories yielded similar forms of rates constants consistent with the phenomenological Arrhenius law, although they were derived from various branches of physics including classical thermodynamics, statistical and quantum mechanics. This convergence supports the validity of the Arrhenius law but also suggests the existence of an even simpler underlying principle. A reductionnist approach is proposed here in which the energetic exponential factor is a conditional probability of sufficient energy and the pre-exponential factor is the frequency of recurrence of the configuration favorable to the reaction, itself proportional to a configurational probability in a chaotic system. This minimalist while rigorous mathematical approach makes it possible to bypass certain questionable postulates of more sophisticated theories and clarifies the meaning of the different types of energies used: activation energy, threshold energy and chemical energy.

Optical reference geometry and inertial forces in Kerr-de Sitter spacetimes

Year: 2007
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Optical reference geometry and related concept of inertial forces are investigated in Kerr-de Sitter spacetimes. Properties of the inertial forces are summarized and their typical behaviour is illustrated. The intuitive 'Newtonian' application of the forces in the relativistic dynamics is demonstrated in the case of the test particle circular motion, static equilibrium positions and perfect fluid toroidal configurations. Features of the optical geometry are illustrated by the embedding diagrams of its equatorial plane. The embedding diagrams do not cover whole the stationary regions of the spacetimes, therefore the limits of embeddability are established. A shape of the embedding diagrams is related to the behaviour of the centrifugal force and it is characterized by the number of turning points of the diagrams. Discussion of the number of embeddable photon circular orbits is also included and the typical embedding diagrams are constructed. The Kerr-de Sitter spacetimes are classified according to the properties of the inertial forces and embedding diagrams.

description: The purposes of the present research are: a) The designing of a learning environment based on the processing of authentic texts in which the message is transmitted through the combination of verbal and visual modes, b) The investigation of the influence of this learning environment on the develop¬ment of school age children's ability to produce different kinds of multi-modal texts. In the research participated 25 7th grade students who attended a private school in a suburb of East Attica. The data used in the research were the diagrams and (lie texts that the students produced during the instructional intervention which lasted six months. Results of the research showed that the participation of the children in a learning environment which gave them the opportunity to read a diagram and transform it in sentences that constitute a certain text type helped them cm the one hand to produce texts that are characterized by systematic use of functional characteristics that differentiate different text types and on the other hand to become aware of the met cognitive skills and strategies that are involved in the writing process of multi-modal texts.

description: We report on the nonlocal gauge invariant operator of dimension two, F 1/D^2 F. We are able to localize this operator by introducing a suitable set of (anti)commuting antisymmetric tensor fields. Starting from this, we succeed in constructing a local gauge invariant action containing a mass parameter, and we prove the renormalizability to all orders of perturbation theory of this action in the linear covariant gauges using the algebraic renormalization technique. We point out the existence of a nilpotent BRST symmetry. Despite the additional (anti)commuting tensor fields and coupling constants, we prove that our model in the limit of vanishing mass is equivalent with ordinary massless Yang-Mills theories by making use of an extra symmetry in the massless case. We also present explicit renormalization group functions at two loop order in the MSbar scheme.
