description: There are two distinct approaches to the study of initial value problem of the periodic box-ball systems. One way is the rigged configuration approach due to Kuniba--Takagi--Takenouchi and another way is the 10-elimination approach due to Mada--Idzumi--Tokihiro. In this paper, we describe precisely interrelations between these two approaches.

Authoritarianism and the closure phenomenon
Creators: name: Duncan, Frances Mary
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study was to note the effect of certain variables on perceptual closure. Closure has been defined by Mooney (1951) as, "the facility with which individuals can apprehend the structural implications of a confused or incomplete visual configuration." Since research into the effect of variables such as age, sex, and intelligence have yielded few results, it was thought that the field of personality traits might be a lucrative one in which to look for factors affecting closure ability. Authoritarianism was chosen as a possible starting-point because it has been shown that high authoritarians are high in rigidity, a factor having a deterrent effect on closure. (Luchins 1959) The Pensacola Z Scale (Jones 1957) was used as the measure of authoritarian personality, since it consists of four factored, separately scorable, subscales: anxiety; dependency; hostility; and rigidity. The closure phenomenon was measured by Mooney's Closure Test (1951) because it can be administered to either an individual or a group. The sample consisted of fifty volunteer students attending the University of British Columbia summer session. Subjects were divided into two groups for testing purposes; one group received the Closure Test first, and the other received the Pensacola first. The purpose of this procedure was to randomize the effects of the two tests on each other. Analysis of the data yielded a Pearson Product-Moment coefficient of -.345, significant at the 5% level, between Closure and the total Pensacola scores, which supported the original hypothesis that there would be an inverse relationship between scores obtained on a measure of authoritarianism and those obtained on a measure of closure. When Closure was correlated with each of the Pensacola subscales, only two were significant; closure-anxiety (-.32) at 57% level, and closure-dependency (-.40) at the 1% level. The other two coefficients can only be regarded as chance occurrences. The multiple correlation coefficient of -.495 calculated between closure, and anxiety and dependency, indicated the better predictive value of the combined scales of dependency and anxiety over the use of them singly, or over the use of the total Pensacola scale. From this study it was concluded that high authoritarians possess qualities which interfere with the ability necessary for achieving closure. Also, the results of this study point to the fact that one place to look for variables affecting closure is within the field of personality traits.

Subjects: subject: Craniofacial growthm dental development, Skeletal maturation, Genetic variation, WNT, RUNX2

description: Background
This study evaluated if genetic variations in the WNT family members and RUNX2 are associated with craniofacial maturation, investigating dental and skeletal maturity in children and teenagers.
Methods
Radiographs from pre-orthodontic treatment of Brazilian patients (7 to 17 years-old) were used to assess dental (panoramic radiographs) and skeletal maturity (cephalometric radiographs). The chronological age (CA) was calculated based on the date of birth and the time the radiographs were performed. For the dental maturity analysis, the Demirjian (1973) method was used and a delta [dental age - chronological age (DA-CA)] was calculated. For the skeletal maturity analysis, the Baccetti et al. (2005) method was used and the patients were classified as “delayed skeletal maturation”, “advanced skeletal maturation” or “normal skeletal maturation”. DNA isolated from buccal cells was used for genotyping of two genetic variations in WNT family genes: rs708111 (G > A) in WNT3A and rs1533767 (G > A) in WNT11; and two genetic variations in RUNX2: rs1200425 (G > A) and rs59983488 (G > T). A statistical analysis was performed and values of p < 0.05 indicated a significant difference.
Results
There were no associations between dental maturity and genotypes (p > 0.05). In the skeletal maturity analysis, the allele A in the rs708111 (WNT3A) was statistically more frequent in patients with delayed skeletal maturation (Prevalence Ratio = 1.6; 95% Confidence Interval = 1.00 to 2.54; p-value = 0.042).
Conclusions
The rs708111 in the WNT3A gene impacts on skeletal maturation.

Transformation of Optical Vortex Beams by Holograms with Embedded Phase Singularity

Year: 2009
Subjects: subject: Optics (physics.optics)

description: Spatial characteristics of diffracted beams produced by the "fork" holograms from incident circular Lauerre-Gaussian modes are studied theoretically. The complex amplitude distribution of a diffracted beam is described by models of the Kummer beam or of the hypergeometric-Gaussian beam. Physically, in most cases its structure is formed under the influence of the divergent spherical wave originating from the discontinuity in the beam spatial profile or its derivatives caused by the hologram's groove bifurcation. Presence of this wave is manifested by the ripple structure in the near-field diffracted beam profiles and in the power-law amplitude decay at the beam periphery. Conditions when the divergent wave is not excited are discussed. The diffracted beam carries a screw wavefront dislocation (optical vortex) whose order equals to algebraic sum of the incident beam azimuthal index and the topological charge of the singularity imparted by the hologram. The input beam singularity can be healed when the above sum is zero. In such cases the diffracted beam can provide better energy concentration in the central intensity peak than the Gaussian beam whose initial distribution coincides with the Gaussian envelope of the incident beam. Applications are possible for generation of optical-vortex beams with prescribed properties and for analyzing the optical-vortex beams in problems of information processing.

Measurement of the depth of equilibrium saltation layers
Creators: name: Cherewick, Harvey Richard
Publisher: name: University of British Columbia
Year: 2011

description: Generally, the problem studied in this dissertation concerns a particular phenomenon encountered in conveying granular solids in gaseous-solids phase horizontal transport. The phenomenon is that at a certain velocity particles will no longer be conveyed, but will settle on the tube bottom forming a layer of stationary solids. Specifically, the goal of this study was to obtain a relationship between the depth of these layers and all the pertinent variables. This relationship was found to be [formula omitted] where: r is the layer depth d is the particle diameter D is the test section pipe diameter g is the local acceleration of gravity W is the solids flow rate/pipe cross-section area Pp is the particle density P is the air density The values or range of values of the pertinent variables for which the above relationship applies is as follows: d 0.032 to 0.201 inches D 2 and 3 inches W 0.68 to 33.3 lb/sec - ft² Pp 15 to 79 lb/cu.ft. P 0.073 lb/cu.ft. Tests were conducted using nearly spherical particles in 100° F, 0.5 psig air. Ambient temperature ranged from 70 - 72° F.

A Common Thread

Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The structures, the phase diagrams, and the appearance of a neutron resonance in the superconducting state provide phenomenological evidence which relate the heavy fermion, cuprate and Fe superconductors. Single- and multi-band Hubbard models have been found to describe a number of the observed properties of these materials so that it is reasonable to examine the origin of the pairing interaction in these models. Here based on the experimental phenomenology and studies of the momentum and frequency dependence of the pairing interaction for Hubbard-like models, we suggest that spin-fluctuation mediated pairing is the common thread linking this broad class of superconducting materials.
description: This work arose from an invitation to present an overview regarding "the mechanism of high temperature superconductivity including the cuprates and Fe- pnictides" at the 9th International Conference on Materials and Mechanisms of Superconductivity held in Tokyo (September 7-12, 2009)
PACS-CS results for 2+1 flavor lattice QCD simulation on and off the physical point

description: We report on the PACS-CS project focusing on a direct simulation of 2+1 flavor QCD on the physical point and chiral analysis of meson and baryon masses off the physical point with both the SU(2) and SU(3) chiral perturbation theories. Configurations are generated with the O(a)-improved Wilson quark action and the Iwasaki gauge action. The up-down quark is simulated by employing the DDHMC algorithm with several improvements and the UV-filtered PHMC algorithm is implemented for the strange quark. We investigate the convergence behaviors of the SU(2) and SU(3) chiral expansions up to NLO for the pseudoscalar meson sector, where the up-down quark mass ranges from 3 MeV to 24 MeV and the strange quark mass is chosen around the physical value. The fit results for the low energy constants are compared with those recently obtained by other groups. We also discuss the importance of the direct simulation at the physical point by comparing the physical quantities measured on the physical point with those estimated by the extrapolation method.

description: We show for the first time that a planar metamaterial, an array of coupled metal split-ring resonators with a unit cell lacking mirror symmetry, exhibits asymmetric transmission of terahertz radiation (0.25-2.5 THz) propagating through it in opposite directions. This intriguing effect, that is compatible with Lorentz reciprocity and time-reversal, depends on a directional difference in conversion efficiency of the incident circularly polarized wave into one of opposite handedness, that is only possible in lossy low-symmetry planar chiral metamaterials. We show that asymmetric transmission is linked to excitation of enantiomerically sensitive plasmons, these are induced charge-field excitations that depend on the mutual handedness of incident wave and metamaterial pattern. Various bands of positive, negative and zero phase and group velocities have been identified indicating the opportunity to develop polarization sensitive negative index and slow light media based on such metamaterials.

description: Digital Watermarking is used for copyright protection and authentication. In the proposed system, a Dual Watermarking Scheme based on DWT SVD with chaos encryption algorithm, will be developed to improve the robustness and protection along with security. DWT and SVD have been used as a mathematical tool to embed watermark in the image. Two watermarks are embedded in the host image. The secondary is embedded into primary watermark and the resultant watermarked image is encrypted using chaos based logistic map. This provides an efficient and secure way for image encryption and transmission. The watermarked image is decrypted and a reliable watermark extraction scheme is developed for the extraction of the primary as well as secondary watermark from the distorted image.

description: Detailed spin-wave spectra of magneto-electric LiNiPO4 have been measured by neutron scattering at low temperatures in the commensurate (C) antiferromagnetic (AF) phase with ordering temperature 20.8 K. An anomalous low-energy mode is observed at the modulation vector of the incommensurate (IC) AF phase appearing above the 20.8 K. A linear spin-wave model based on Heisenberg exchange couplings and single ion anisotropies accounts for all the observed spin-wave dispersions and intensities. Along the b axis an unusually strong next-nearest-neighbor AF coupling competes with the dominant nearest-neighbor AF exchange interaction and causes the IC structure.

Controlling electronic and adiabatic isolation of quantum dots from the substrate: An ionization-energy theoretic study

description: Recent controversy on the quantum dots dephasing mechanisms (between pure and inelastic) is re-examined by isolating the quantum dots from their substrate by using the appropriate limits of the ionization energy theory and the quantum adiabatic theorem. When the phonons in the quantum dots are isolated adiabatically from the phonons in the substrate, the elastic or pure dephasing becomes the dominant mechanism. On the other hand, for the case where the phonons from the substrate are non-adiabatically coupled to the quantum dots, the inelastic dephasing process takes over. This switch-over is due to different elemental composition in quantum dots as compared to its substrate. We also provide unambiguous analyses as to understand why GaAs/AlGaAs quantum dots may only have pure dephasing while InAs/GaAs quantum dots give rise to the inelastic dephasing as the dominant mechanism. Our study accentuates the importance of the elemental composition (of both quantum dots and substrate) in evaluating the dephasing mechanisms of quantum dots.

Grammar and logic
Creators: name: Fielding, David Anthony
Publisher: name: University of British Columbia
Year: 2011

description: The structure of our world is given in the grammar of our native tongue. If so people whose native tongue has quite a different grammar must be living in a quite different world. A logic such as Aristotle's may seem universal to the speakers of Greek, in fact it may seem universal to speakers of any Indo-European tongue, but the logic will hold good only for the 'universe' of the language or language-family in question. This implies a relationship between logic and grammar rather like the one Russell and Whitehead -claimed for mathematics and logic. Their Principia Mathematica tried to show that the mathematical notion of number rests on, or arises out of, the logical notion of class, that is, we come to understand what a number is through our grasp of what a class is. This thesis is a kind of Principia Logica: it suggests that the whole framework of common sense logic rests on, or arises out of, the grammatical structure of the language the logic was conceived in or took shape in terms of. And if so logical criteria come into being and take shape inside a language or language-family, and are dependent for their validity and even for their meaning on the structure of the language in question. To test, or to try to test, a mode of thought or an argument form against a logical system would be to put the cart before the horse: the logic only makes sense because the form of argument or mode of thought was there already. If so philosophers and logicians ought to think of the words 'world', 'universe' and 'universal' with tongue in cheek. In so far as a judgment seems to us universally true it is unlikely to hold good for the world of an alien language family. If our world is not the only world anybody writing logic or philosophy down ought to make it clear whose world he has in mind - and to do this it may be enough to make sure it is addressed to somebody in particular. Western philosophers seem to have addressed themselves to the whole world, or to mankind, or God. This thesis shows, if nothing else, how hard it can be to address even one other human being. To sum up with another analogy; it seems to me, as a single man, that the difference between one and two is greater than the difference between any other two numbers. There may be a world of difference between zero and one, but between one and two there's all the difference in the world - and that's the difference that matters. Perhaps the only way 1,000 differs from 1,001, as Frege puts it, is in the expression on its face.

How to quantify energy landscapes of solids
Creators: name: Oganov, Artem R.

Publisher: name: arXiv
Year: 2009
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: We explore whether the topology of energy landscapes in chemical systems obeys any rules and what these rules are. To answer this and related questions we use several tools: (i)Reduced energy surface and its density of states, (ii) descriptor of structure called fingerprint function, which can be represented as a one-dimensional function or a vector in abstract multidimensional space, (iii) definition of a ''distance'' between two structures enabling quantification of energy landscapes, (iv) definition of a degree of order of a structure, and (v) definitions of the quasi-entropy quantifying structural diversity. Our approach can be used for rationalizing large databases of crystal structures and for tuning computational algorithms for structure prediction. It enables quantitative and intuitive representations of energy landscapes and reappraisal of some of the traditional chemical notions and rules. Our analysis confirms the expectations that low-energy minima are clustered in compact regions of configuration space ("funnels") and that chemical systems tend to have very few funnels, sometimes only one. This analysis can be applied to the physical properties of solids, opening new ways of discovering structure-property relations. We quantitatively demonstrate that crystals tend to adopt one of the few simplest structures consistent with their chemistry, providing a thermodynamic justification of Pauling's fifth rule.

Here we study in detail the structure of this one-cocycle. In particular we show that its non-triviality relates to the presence of a (Dirac) magnetic monopole bundle. We also explicitely present the finite version of the cocycle.

description: We describe the control system for the new DAPHNE  ϕ-factory under construction at the Frascati National Laboratories. The system is based on a centralized architecture for simplicity and reliabilty. A central processor unit coordinates all communications between the consoles and the lower level distributed processing power, and continuosly updates a central memory which contains the whole machine status. This memory constitutes the machine database prototype. A simple message passing scheme built on a system of mailboxes takes advantage of high speed busses and of Fiber Optic interfaces. Macintosh II personal computers are used as consoles. The lower levels are all built using the VME standard.

description: At the end of February 1991, a 'triple-axis' high-resolution diffractometer for on powder sample measurements with synchrotron radiation was put in operation on the Adone wiggler line BX1 at Frascati. The diffractometer is based on a Seifert goniometer, designed according to our specifications. During the project, particular attention was paid in assuring the highest reliability together with great flexibility in the use. In fact, the diffractometer can also be used in a 'medium resolution' configuration. For preliminary alignment and data collection, it is possible to operate with a traditional x-ray tube, too. The alignment procedure of the diffractometer to the x-ray beam is very easy. Powder samples can be measured both on the flat holder and on the capillary. An IBM PC computer is used for the instrument actuation and preliminary on-line data collection, while a large software package has been developed for the data analysis performed by a Macintosh IIcx. The instrument performance has been tested with a standard Si sample and quartz and Ni oxide samples. For the two possible resolution configurations, a test on a NiO sample gave FWHM values of 0.16^o and 0.04^o, respectively, for the [012] peak.

description: The absorption cross section is studied in the low-frequency region for a propagating scalar field under the warped AdS$_3$ black hole background in the topologically massive gravity. It can be shown that the absorption cross section is significantly deformed by the gravitational Chern-Simons term, which is proportional to the scattering area of black hole with an additional contribution depending on the left-moving and right-moving temperatures. It means that the cross section is larger than the area in spite of the s-wave limit. Finally, we discuss the left-right quasinormal modes for the scalar perturbation in this black hole.

description: Density functional theory calculations demonstrate that rocksalt MgN is a magnetic material at the verge of half-metallicity, with an electronic structure robust against strong correlations and spin-orbit interaction. Furthermore the calculated heat of formation describes the compound as metastable and suggests that it can be fabricated by tuning the relative Mg and N abundance during growth. Intriguingly the equilibrium lattice constant is close to that of MgO, so that MgN is likely to form as an inclusion during the fabrication of N-doped MgO. We then speculate that the MgO/MgN system may represent a unique materials platform for magnetic tunnel junctions not incorporating any transition metals.

description: We discuss existency conditions for toponium bound states and evaluate the wave function at the origin, comparing different models for the static interquark potential. We evaluate the production cross-section for J^PC=0^+-,1^-- for the case of a static Coulomb Potential. For the pseudoscalar case, which at LHC and SSC would be produced with the highest cross-section, we compare the signal with the expected QCD background. We find that the present lower limits on the top mass almost exclude the possibility of these bound states and their detectability.

description: Electromagnetic interactions between colliding heavy ions at the Large Hadron Collider (LHC) at CERN will give rise to localized beam losses that may quench superconducting magnets, apart from contributing significantly to the luminosity decay. To quantify their impact on the operation of the collider, we have used a three-step simulation approach, which consists of optical tracking, a Monte-Carlo shower simulation and a thermal network model of the heat flow inside a magnet. We present simulation results for the case of Pb ion operation in the LHC, with focus on the ALICE interaction region, and show that the expected heat load during nominal Pb operation is 40% above the quench level. This limits the maximum achievable luminosity. Furthermore, we discuss methods of monitoring the losses and possible ways to alleviate their effect.

Wake Fields and Impedance

description: Knowledge of the electromagnetic interaction between a beam and the surrounding vacuum chamber is necessary in order to optimize the accelerator per-formance in terms of stored current. Many instability phenomena may occur in the machine because of the fields produced by the beam and acting back on itself as in a feedback device. Basically, these fields produce an extra voltage and energy gain, affecting the longitudinal dynamics, and a transverse momentum kick which deflects the beam. In this paper we describe the main features of this interaction with typical machine components.

description: This deliverable has been projected as the long-awaited and definitive description of the Data Lake, that mythical answer to all dwelling technical questions in the whole FAIR-EASE project. The approach presented in this document tries to address that expectation, yet allows itself to do so without conforming to any assumptions derived from common existing definitions of a Data Lake. Instead, it applies high-level systems engineering on the base requirements as gathered in D5.1 and presented during the one-on-one pilot interviews, to conclude in a General Architecture plan that replaces the "Central Data Lake" scenario with a "Many Lakes" one. Overall, this deliverable is intended to provide a framework for planning the rest of the work and should not be evaluated solely based on how accurately it describes the end result when the project finishes. It is as much a management tool as an actual architecture document, and we hope that it will serve as a useful guide for all stakeholders involved in the FAIR-EASE project.

description: Background

Genome-wide association studies (GWAS) have identified hundreds of genetic loci associated with kidney function. By combining these findings with post-GWAS information (e.g., statistical fine-mapping to identify independent association signals and to narrow down signals to causal variants; or different sources of annotation data), new hypotheses regarding physiology and disease aetiology can be obtained. These hypotheses need to be tested in laboratory experiments, for example, to identify new therapeutic targets. For this purpose, the evidence obtained from GWAS and post-GWAS analyses must be processed and presented in a way that they are easily accessible to kidney researchers without specific GWAS expertise.
Main

Here we present KidneyGPS, a user-friendly web-application that combines genetic variant association for estimated glomerular filtration rate (eGFR) from the Chronic Kidney Disease Genetics consortium with annotation of (i) genetic variants with functional or regulatory effects (“SNP-to-gene” mapping), (ii) genes with kidney phenotypes in mice or human (“gene-to-phenotype”), and (iii) drugability of genes (to support re-purposing). KidneyGPS adopts a comprehensive approach summarizing evidence for all 5906 genes in the 424 GWAS loci for eGFR identified previously and the 35,885 variants in the 99% credible sets of 594 independent signals. KidneyGPS enables user-friendly access to the abundance of information by search functions for genes, variants, and regions. KidneyGPS also provides a function (“GPS tab”) to generate lists of genes with specific characteristics thus enabling customizable Gene Prioritisation (GPS). These specific characteristics can be as broad as any gene in the 424 loci with a known kidney phenotype in mice or human; or they can be highly focussed on genes mapping to genetic variants or signals with particularly with high statistical support. KidneyGPS is implemented with RShiny in a modularized fashion to facilitate update of input data (https://kidneygps.ur.de/gps/).
Conclusion

With the focus on kidney function related evidence, KidneyGPS fills a gap between large general platforms for accessing GWAS and post-GWAS results and the specific needs of the kidney research community. This makes KidneyGPS an important platform for kidney researchers to help translate in silico research results into in vitro or in vivo research

Confirmation of a recent bipolar ejection in the very young hierarchical multiple system IRAS 16293-2422

description: We present and analyze two new high-resolution (approx 0.3 arcsec), high-sensitivity (approx 50 uJy beam-1) Very Large Array 3.6 cm observations of IRAS 16293-2422 obtained in 2007 August and 2008 December. The components A2alpha and A2beta recently detected in this system are still present, and have moved roughly symmetrically away from source A2 at a projected velocity of 30-80 km s-1. This confirms that A2alpha and A2beta were formed as a consequence of a very recent bipolar ejection from A2. Powerful bipolar ejections have long been known to occur in low-mass young stars, but this is -to our knowledge-- the first time that such a dramatic one is observed from its very beginning. Under the reasonable assumption that the flux detected at radio wavelengths is optically thin free-free emission, one can estimate the mass of each ejecta to be of the order of 10^-8 Msun. If the ejecta were created as a consequence of an episode of enhanced mass loss accompanied by an increase in accretion onto the protostar, then the total luminosity of IRAS 16293-2422 ought to have increased by 10-60% over the course of at least several months. Between A2alpha and A2beta, component A2 has reappeared, and the relative position angle between A2 and A1 is found to have increased significantly since 2003-2005. This strongly suggests that A1 is a protostar rather than a shock feature, and that the A1/A2 pair is a tight binary system. Including component B, IRAS 16293-2422 therefore appears to be a very young hierarchical multiple system.

Turbulent flow in concentric and eccentric annuli
Creators: name: Denton, John Douglas
Publisher: name: University of British Columbia
Year: 2011

description: The turbulent flow of air through the annular gap between two tubes was studied experimentally, both with the tubes concentric and with the inner tube at eccentricities of 50% and 100%. Air velocities were measured using small traversable impact tubes. The shear stresses on the boundaries were studied both by measuring the pressure gradient and by means of a calibrated shear probe attached to the inner tube. For all three annuli complete nondimensional velocity profiles were obtained at Reynolds numbers around 55,000 and the variation of average friction factor with Reynolds number was studied in the Reynolds number range 20,000 -55,000. The variation of local shear stress around the surface of the inner tube was obtained for the eccentric annuli. The results for the concentric annulus agree well with previous investigations. For the eccentric annuli the results are compared qualitatively with Deissler and Taylor's semi-theoretical investigation. The agreement is not good and this is thought 'to show that the Deissler-Taylor method is not applicable to annuli. It is concluded that the study of velocity profiles in non-symmetrical ducts is of little help in obtaining quantitative heat transfer data.
