description: In 1981, Takeuti introduced quantum set theory by constructing a model of set theory based on quantum logic represented by the lattice of closed linear subspaces of a Hilbert space in a manner analogous to Boolean-valued models of set theory, and showed that appropriate counterparts of the axioms of Zermelo-Fraenkel set theory with the axiom of choice (ZFC) hold in the model. In this paper, we aim at unifying Takeuti's model with Boolean-valued models by constructing models based on general complete orthomodular lattices, and generalizing the transfer principle in Boolean-valued models, which asserts that every theorem in ZFC set theory holds in the models, to a general form holding in every orthomodular-valued model. One of the central problems in this program is the well-known arbitrariness in choosing a binary operation for implication. To clarify what properties are required to obtain the generalized transfer principle, we introduce a class of binary operations extending the implication on Boolean logic, called generalized implications, including even non-polynomially definable operations. We study the properties of those operations in detail and show that all of them admit the generalized transfer principle. Moreover, we determine all the polynomially definable operations for which the generalized transfer principle holds. This result allows us to abandon the Sasaki arrow originally assumed for Takeuti's model and leads to a much more flexible approach to quantum set theory.

description: In this paper we study several closely related fundamental problems for words and matrices. First, we introduce the Identity Correspondence Problem (ICP): whether a finite set of pairs of words (over a group alphabet) can generate an identity pair by a sequence of concatenations. We prove that ICP is undecidable by a reduction of Post's Correspondence Problem via several new encoding techniques. In the second part of the paper we use ICP to answer a long standing open problem concerning matrix semigroups: "Is it decidable for a finitely generated semigroup S of square integral matrices whether or not the identity matrix belongs to S?". We show that the problem is undecidable starting from dimension four even when the number of matrices in the generator is 48. From this fact, we can immediately derive that the fundamental problem of whether a finite set of matrices generates a group is also undecidable. We also answer several question for matrices over different number fields. Apart from the application to matrix problems, we believe that the Identity Correspondence Problem will also be useful in identifying new areas of undecidable problems in abstract algebra, computational questions in logic and combinatorics on words.

description: With any self-similar action of a finitely generated group $G$ of automorphisms of a regular rooted tree $T$ can be naturally associated an infinite sequence of finite graphs $\{Γ_n\}_{n\geq 1}$, where $Γ_n$ is the Schreier graph of the action of $G$ on the $n$-th level of $T$. Moreover, the action of $G$ on $\partial T$ gives rise to orbital Schreier graphs $Γ_ξ$, $ξ\in \partial T$. Denoting by $ξ_n$ the prefix of length $n$ of the infinite ray $ξ$, the rooted graph $(Γ_ξ,ξ)$ is then the limit of the sequence of finite rooted graphs $\{(Γ_n,ξ_n)\}_{n\geq 1}$ in the sense of pointed Gromov-Hausdorff convergence. In this paper, we give a complete classification (up to isomorphism) of the limit graphs $(Γ_ξ,ξ)$ associated with the Basilica group acting on the binary tree, in terms of the infinite binary sequence $ξ$.

description: We systematically investigate the mass spectra of $\{Q\bar{s}\}\{\bar{Q}^{(')}s\}$ molecular states in the framework of QCD sum rules. The interpolating currents representing the molecular states are proposed. Technically, contributions of the operators up to dimension six are included in operator product expansion (OPE). The masses for molecular states with various $\{Q\bar{s}\}\{\bar{Q}^{(')}s\}$ configurations are presented. The result $4.36\pm0.08 GeV$ for the $D_{s}^{*}\bar{D}_{s0}^{*}$ molecular state is consistent with the mass $4350^{+4.6}_{-5.1}\pm0.7 MeV$ of the newly observed $X(4350)$, which could support $X(4350)$ interpreted as a $D_{s}^{*}\bar{D}_{s0}^{*}$ molecular state.

description: Private queries allow a user Alice to learn an element of a database held by a provider Bob without revealing which element she was interested in, while limiting her information about the other elements. We propose to implement private queries based on a quantum key distribution protocol, with changes only in the classical post-processing of the key. This approach makes our scheme both easy to implement and loss-tolerant. While unconditionally secure private queries are known to be impossible, we argue that an interesting degree of security can be achieved, relying on fundamental physical principles instead of unverifiable security assumptions in order to protect both user and database. We think that there is scope for such practical private queries to become another remarkable application of quantum information in the footsteps of quantum key distribution.

description: We report on a new class of fast-roll inflationary models. In a huge part of its parameter space, inflationary perturbations exhibit quite unusual phenomena such as scalar and tensor modes freezing out at widely different times, as well as scalar modes reentering the horizon during inflation. In another, narrower range of parameters, this class of models agrees with observations. One specific point in parameter space is characterized by extraordinary behavior of the scalar perturbations. Freeze-out of scalar perturbations as well as particle production at horizon crossing are absent. Also the behavior of the perturbations around this quasi-de Sitter background is dual to a quantum field theory in flat space-time. Finally, the form of the primordial power spectrum is determined by the interaction between different modes of scalar perturbations.

Total management information system concept
Creators: name: Allsopp, Harold Robert
Publisher: name: University of British Columbia
Year: 2011

description: The objective of this thesis is to develop and define the concept of a total management information system. The term "total system" has been grossly misrepresented since its coinage, however, the misuse can be attributed to ignorance of its full meaning. The misuse is also attributed to narrow thinking on behalf of the user for its application has mainly been directed to a specific circumstance. The study defines the term "total management information system" and it also outlines the attributes which make up the total system. As in all situations where an ideal is created, there is resistence to reaching the ideal - these barriers are enumerated and commented upon. To test the validity of the concept, it is applied to an existing company's informational system by the methodology of a systems analysis. Conclusions are reached on the soundness of the concept and on the status of the case company toward its claim of holding the totality status. Primary research was conducted on the theory of a total system; secondary research was conducted into the existing systems of the case company. Throughout the study, observations were made concerning the problems associated with the topic and an evaluation is made on the status of the evolution of the total information system.

description: We express the Noether charge entropy density of a black brane in anti-deSitter space in terms of local operators in the anti-deSitter space bulk. We find that Wald's expression for the Noether charge entropy needs to be modified away from the horizon by an additional term that vanishes on the horizon. We then determine the field theory dual of the Noether charge entropy for theories that asymptote to Einstein theory. We do so by calculating the value of the entropy density at the anti-deSitter space boundary and applying the standard rules of the AdS/CFT correspondence. We interpret the variation of the entropy density operator from the horizon to the boundary as due to the renormalization of the effective gravitational couplings as they flow from the ultra-violet to the infra-red. We discuss the cases of Einstein-Hilbert theory and f(R) theories in detail and make general comments about more complicated cases.

We also provide a computational method to classify all such hypersurfaces that admit an automorphism of prime order p. In particular, we show that p<2^{n+1} and that any such hypersurface admitting an automorphism of order p>2^n is isomorphic to the Klein n-fold. We apply our method to compute exhaustive lists of automorphism of prime order of smooth cubic threefolds and fourfolds. Finally, we provide an application to the moduli space of principally polarized abelian varieties.

description: We study a spatial Prisoner's dilemma game with two types (A and B) of players located on a square lattice. Players following either cooperator or defector strategies play Prisoner's Dilemma games with their 24 nearest neighbors. The players are allowed to adopt one of their neighbor's strategy with a probability dependent on the payoff difference and type of the given neighbor. Players A and B have different efficiency in the transfer of their own strategy therefore the strategy adoption probability is reduced by a multiplicative factor (w < 1) from the players of type B. We report that the motion of the influential payers (type A) can improve remarkably the maintenance of cooperation even for their low densities.

description: Thoracic endometriosis syndrome (TES) is a rare disease in which a functioning endometrial tissue is observed in the pleura, lung, parenchyma, airways, and/or diaphragm. The optimal management of this disease remains a matter of debate. We aimed to report TES cases and their effective hormonal treatment and management. In this retrospective study, women presented as catamenial hemoptysis (CH) diagnosed with thoracic endometriosis were included. The main outcome of measure was cessation or recurrence of the clinical manifestations of thoracic endometriosis. The mean onset age of the 14 patients was 30.21 ± 5.40 years. CH was characteristic symptom of these patients. All patients underwent chest computed tomography (CT) scan during menstruation and 2 or 3 weeks after menstruation, which showed the obvious shrinking or disappearance of the lesions. All of the patients were given Gonadotropin releasing hormone agonists (GnRHa) for 3 to 6 months, eleven of them were administered with combined oral contraceptives (COC) cyclically after GnRHa. The median follow-up duration was 24 months. Hemoptysis recurrence was observed in one patient. CH is a rare clinical entity of thoracic endometriosis, the change of CT images during and after menstruation or the response to GnRHa were helpful for accurate diagnosis. Hormonal treatment with GnRHa followed by COCs cyclically could be employed for efficient management of thoracic endometriosis.
A Variant of the Stanley Depth for Multisets

subject: 06A07

description: We define and study a variant of the \emph{Stanley depth} which we call \emph{total depth} for partially ordered sets (posets). This total depth is the most natural variant of Stanley depth from $\llbracket S_k\rrbracket$ -- the poset of nonempty subsets of $\{1,2,\dots,k\}$ ordered by inclusion -- to any finite poset. In particular, the total depth can be defined for the poset of nonempty submultisets of a multiset ordered by inclusion, which corresponds to a product of chains with the bottom element deleted. We show that the total depth agrees with Stanley depth for $\llbracket S_k\rrbracket$ but not for such posets in general. We also prove that the total depth of the product of chains $\bm{n}^k$ with the bottom element deleted is $(n-1)\lceil{k/2}\rceil$, which generalizes a result of Bir{ó}, Howard, Keller, Trotter, and Young (2010). Further, we provide upper and lower bounds for a general multiset and find the total depth for any multiset with at most five distinct elements. In addition, we can determine the total depth for any multiset with $k$ distinct elements if we know all the interval partitions of $\llbracket S_k\rrbracket$.

description: The problem of model selection arises in a number of contexts, such as compressed sensing, subset selection in linear regression, estimation of structures in graphical models, and signal denoising. This paper generalizes the notion of \emph{incoherence} in the existing literature on model selection and introduces two fundamental measures of coherence---termed as the worst-case coherence and the average coherence---among the columns of a design matrix. In particular, it utilizes these two measures of coherence to provide an in-depth analysis of a simple one-step thresholding (OST) algorithm for model selection. One of the key insights offered by the ensuing analysis is that OST is feasible for model selection as long as the design matrix obeys an easily verifiable property. In addition, the paper also characterizes the model-selection performance of OST in terms of the worst-case coherence, μ, and establishes that OST performs near-optimally in the low signal-to-noise ratio regime for N x C design matrices with μ= O(N^{-1/2}). Finally, in contrast to some of the existing literature on model selection, the analysis in the paper is nonasymptotic in nature, it does not require knowledge of the true model order, it is applicable to generic (random or deterministic) design matrices, and it neither requires submatrices of the design matrix to have full rank, nor does it assume a statistical prior on the values of the nonzero entries of the data vector.

description: INTRODUCTION

 

In the introduction, I have chosen to elucidate why I opted for this particular topic.

 

Relevance

 

As I have previously mentioned, there is much to contemplate, and perhaps this became the primary reason. In this work, I will convey all the known information about gravitational waves, encompassing theories and assumptions, and I will also conduct a data analysis. For a deeper understanding of this topic, I have joined the GRANDMA project, which investigates the nature of gravitational waves at a highly advanced level. I believe that gravitational waves represent a new trend in contemporary and future astrophysics.

 

Gravitational waves are an extraordinarily intriguing object that demands observation. Thanks to gravitational waves, we can discover new astronomical objects. Additionally, gravitational waves have been instrumental in reaffirming numerous scientific theories, such as the general theory of relativity and the theory of the big bang. I am of the opinion that gravitational waves will assist us in better comprehending the Universe, and perhaps even draw scientists closer to the creation of new theories (such as the theory of everything).

 

Objective: Analysis of data from gravitational wave signals on gravitational interferometers. Search for sources of gravitational waves in the visible range.

 

Tasks:

1. Analyze all data on gravitational waves known at the moment.

2. Extract parameters of gravitational waves necessary for their registration.

3. Participate in the program to search for sources of gravitational waves in the visible range.

description: The nature of the gravitational interaction between ordinary and dark matter is still open. Any deviation from universality or the Newtonian law also modifies the standard assumption of collisionless dark matter. On the other hand, obtaining a Yukawa-like large-distance modification of the gravitational potential is a nontrivial problem, that has so far eluded a consistent realization even at linearized level. We propose here a theory providing a Yukawa-like potential, by coupling non-derivatively the two metric fields related respectively to the visible and dark matter sectors, in the context of massive gravity theories where the local Lorentz invariance is broken by the different coexisting backgrounds. This gives rise to the appropriate mass pattern in the gravitational sector, producing a healthy theory with the Yukawa potential. Our results are of a special relevance in the scenario of dark matter originated from the mirror world, an exact duplicate of the ordinary particle sector.

description: We investigate the SL(2,R) invariant geodesic curves with the as- sociated invariant distance function in parabolic geometry. Parabolic geom- etry naturally occurs in the study of SL(2,R) and is placed in between the elliptic and the hyperbolic (also known as the Lobachevsky half-plane and 2- dimensional Minkowski half-plane space-time) geometries. Initially we attempt to use standard methods of finding geodesics but they lead to degeneracy in this setup. Instead, by studying closely the two related elliptic and hyperbolic geometries we discover a unified approach to a more exotic and less obvious parabolic case. With aid of common invariants we describe the possible dis- tance functions that turn out to have some unexpected, interesting properties.

A New Methodology for Generalizing Unweighted Network Measures

description: Several important complex network measures that helped discovering common patterns across real-world networks ignore edge weights, an important information in real-world networks. We propose a new methodology for generalizing measures of unweighted networks through a generalization of the cardinality concept of a set of weights. The key observation here is that many measures of unweighted networks use the cardinality (the size) of some subset of edges in their computation. For example, the node degree is the number of edges incident to a node. We define the effective cardinality, a new metric that quantifies how many edges are effectively being used, assuming that an edge's weight reflects the amount of interaction across that edge. We prove that a generalized measure, using our method, reduces to the original unweighted measure if there is no disparity between weights, which ensures that the laws that govern the original unweighted measure will also govern the generalized measure when the weights are equal. We also prove that our generalization ensures a partial ordering (among sets of weighted edges) that is consistent with the original unweighted measure, unlike previously developed generalizations. We illustrate the applicability of our method by generalizing four unweighted network measures. As a case study, we analyze four real-world weighted networks using our generalized degree and clustering coefficient. The analysis shows that the generalized degree distribution is consistent with the power-law hypothesis but with steeper decline and that there is a common pattern governing the ratio between the generalized degree and the traditional degree. The analysis also shows that nodes with more uniform weights tend to cluster with nodes that also have more uniform weights among themselves.

Controlling Energy Gap of Bilayer Graphene by Strain

description: Using the first principles calculations, we show that mechanically tunable electronic energy gap is realizable in bilayer graphene if different homogeneous strains are applied to the two layers. It is shown that the size of energy gap can be simply controlled by adjusting the strength and direction of these strains. We also show that the effect originates from the occurrence of strain-induced pseudo-scalar potentials in graphene. When homogeneous strains with different strengths are applied to each layer of bilayer graphene, transverse electric fields across the two layers can be generated without any external electronic sources, thereby opening an energy gap. The results demonstrate a simple mechanical method of realizing pseudo-electromagnetism in graphene and suggest a maneuverable approach to fabrication of electromechanical devices based on bilayer graphene.

Studies of the blood cells and tunic of the ascidian, Halocynthia Aurantium (Pallas)
Creators: name: Smith, Michael Joseph
Publisher: name: University of British Columbia
Year: 2011

description: The morphology and histochemistry of the blood cells and tunic of the ascidian Halocynthia aurantium were studied. The nature of the tunic was investigated by both chemical and biochemical means. Quantitative studies of the blood of Halocynthia display ten blood cell types, four of which are concentrated in tunic in higher concentrations than in blood. Of these four, two, including an iron bearing cell, display discrete stable aggregation areas in the body of the tunic, and a third is a phagocyte. Histochemical examination of the tunic and blood cells reveals that the tunic fibers and epidermis stain for acid mucopolysaccharide and protein. The spinous processes on the surface of the tunic do not stain like the epidermis or fibers, but do display some similarity to the blood cell type which aggregates in their proximity. There is a coincidence of absorption spectra of methanol extracts of blood cells and tunic, but no particular blood cell has been indicated as the pigment cell. The blood cells, in the tunic, do not display staining properties which would indicate that they are contributing to the carbohydrate component. Morphological characteristics and histochemical properties of epidermis indicate that it is the major tunic secreting tissue. The histogenetic relationship of various blood cells is discussed on the basis of analogous histochemistry and quantitative hematology. The function of particular blood cell types in the tunic is suggested by the discrete positional relationships of cells and the morphology of the tunic. The chemical composition of tunic is approximately 50% protein and 50% carbohydrate. Amino acid analysis of tunic before and after proteolytic enzyme treatment shows that the protein does not have the characteristics of common connective tissue proteins such as collagen, elastin, or others, and that the protein-polysaccharide link probably involves glucosamine and serine. Five per cent of the dry weight of tunic is hexosamine with both galactosamine and glucosamine present in a ratio of 1 to 4. The carbohydrate component of the tunic releases 75% of its weight as glucose upon acid hydrolysis. This carbohydrate consistently displays a negative P.A.S. reaction and is resistant to several cellulose dispersing reagents. The elemental composition of the carbohydrate reveals a hydrogen content which is too low and an oxygen content which is too high to indicate cellulose. Tunic, pronase treated tunic, and tunic carbohydrate were submitted to cellulase, chitinase, and hyaluronidase digestion. None of these materials are subject to degradation by chitinase or hyaluronidase. Tunic is refractory to cellulase. Pronase treated tunic will release 20% of its weight as glucose upon incubation with cellulase. Tunic carbohydrate component will release 55% of its weight as glucose upon cellulase treatment, although chemical properties indicate that it may be more complex than cellulose.

description: We discuss astrophysical implications of the modified gravity model in which the two matter components, ordinary and dark, couple to separate gravitational fields that mix to each other through small mass terms. There are two spin-2 eigenstates: the massless graviton that induces universal Newtonian attraction, and the massive one that gives rise to the Yukawa-like potential which is repulsive between the ordinary and dark bodies. As a result the distances much smaller than the Yukawa radius $r_m$ the gravitation strength between the two types of matter becomes vanishing. If $r_m \sim 10$ kpc, a typical size of a galaxy, there are interesting implications for the nature of dark matter. In particular, one can avoid the problem of the cusp that is typical for the cold dark matter halos. Interestingly, the flat shape of the rotational curves can be explained even in the case of the collisional and dissipative dark matter (as e.g. mirror matter) that cannot give the extended halos but instead must form galactic discs similarly to the visible matter. The observed rotational curves for the large, medium-size and dwarf galaxies can be nicely reproduced. We also briefly discuss possible implications for the direct search of dark matter.

Nonequilibrium Fluctuation Relation for Sheared Micellar Gel in a Jammed State

description: We show that the shear rate at a fixed shear stress in a micellar gel in a jammed state exhibits large fluctuations, showing positive and negative values, with the mean shear rate being positive. The resulting probability distribution functions (PDF's) of the global power flux to the system vary from Gaussian to non-Gaussian, depending on the driving stress and in all cases show similar symmetry properties as predicted by Gallavotti-Cohen steady state fluctuation relation. The fluctuation relation allows us to determine an effective temperature related to the structural constraints of the jammed state. We have measured the stress dependence of the effective temperature. Further, experiments reveal that the effective temperature and the standard deviation of the shear rate fluctuations increase with the decrease of the system size.

description: For a sigma model of AKSZ-type, we show that the local BRST cohomology is isomorphic to the cohomology of the target space differential when restricted to coordinate neighborhoods both in the base and in the target. An analogous result is shown to hold for the cohomology in the space of functional multivectors. Applications of these latter cohomology classes in the context of the inverse problem of the calculus of variation for general gauge systems are also discussed.
