description: This paper is part of a series on the Azimuthally Symmetric Theory of Gravitation (ASTG) which is built on Laplace-Poisson's well known equation. We show herein that the emergent equations from the ASTG, under some critical conditions determined by the spin, do possess repulsive gravitational fields in the polar regions of the gravitating body in question. This places the ASTG on an interesting pedestal to infer the origins of outflows as a repulsive gravitational phenomenon. Outflows are a ubiquitous phenomenon found in star forming systems and their true origin is a question yet to be settled. Given the current thinking on their origin, the direction that the present paper takes is nothing short of an asymptotic break from conventional wisdom; at the very least, it is a complete paradigm shift because gravitation is not at all associated with this process, but rather it is thought to be an all-attractive force that only tries to squash matter together onto a single point. Additionally, we show that the emergent Azimuthally Symmetric Gravitational Field from the ASTG strongly suggests a solution to the supposed Radiation Problem that is thought to be faced by massive stars in their process of formation. That is, at about 8-10Msun radiation from the nascent star is expected to halt the accretion of matter. We show that in-falling material will fall onto the equatorial disk and from there, this material will be channeled onto the forming star via the equatorial plane, thus accretion of mass continues well past the value of about 8-10Msun, albeit via the disk. Along the equatorial plane, the net force (with the radiation force included) on any material there-on right up to the surface of the star is directed toward the forming star, hence accretion of mass by the nascent star is un-hampered.

description: It is of utmost importance that the instrumental music teacher be able to demonstrate proper tone quality, breath control , fingering techniques, and phrasing. He must also understand the problems which the student will encounter and have to overcome in the study of the different instruments. One of the most effective methods of learning is through actual performance . The teacher learns many points during preparation for acceptable performance which may be applied to other instruments as well as the specific problems of that instrument. The writer felt that the performance of a woodwind recital would be the most practical and beneficial project to improve the knowledge of teaching instrumental music.
The clarinet , flute, and oboe were selected for solo performance. A clarinet quartet composed of former students of the writer was also included in the performance. The major works were performed on the clarinet, the performer ' s major instrument . The flute was also selected because it had been studied previously during undergraduate study. The oboe was selected because of the possibilities it offered for phrasing and control not possible on the clarinet and because of the availability of reeds which the writer had learned to make during undergraduate work.
Because of the great many endurance pressures which accompany solo performances, it was necessary to provide a brief rest for the soloist. This need was fulfilled, and the teaching ability of the writer demonstrated by the student quartet composed of four members of the Sky View High School band. The quartet consisted of one junior and three sophomores. They had been playing the clarinet since they entered junior high school . They had studied private ly from one to three years . They agreed to help with the recital, and practices were arranged on Saturday mornings. During the week prior to the recital, special rehearsals were arranged for during their school lunch period.
The choice of an accompanist was a very important consideration. Mrs. Vichy H. Furness was selected for this very v ital role . The works selected for performance were difficult and called for an accompanist of exceptional ability. Mrs. Furness was a source of great assistance in rehearsals as well as the final performance.

description: Pentagon and triangle shapes in Si-28 and C-12 are discussed in relation with nuclear density wave. In the antisymmetrized molecular dynamics calculations, the $K^π=5^-$ band in Si-28 and the $K^π=3^-$ band in C-12 are described by the pentagon and triangle shapes, respectively. These negative-parity bands can be interpreted as the parity partners of the $K^π=0^+$ ground bands and they are constructed from the parity-asymmetric-intrinsic states. The pentagon and the triangle shapes originate in 7alpha and 3alpha cluster structures, respectively. In a mean-field picture, they are described also by the static one-dimensional density wave at the edge of the oblate states. In analysis with ideal alpha cluster models using Brink-Bloch cluster wave functions and that with a simplified model, we show that the static edge density wave for the pentagon and triangle shapes can be understood by spontaneous breaking of axial symmetry, i.e., the instability of the oblate states with respect to the edge density wave. The density wave is enhanced in the Z=N nuclei due to the proton-neutron coherent density waves, while it is suppressed in Z\ne N nuclei.

The stochastic movements of individual streambed grains
Creators: name: Pierce, J. Kevin
Publisher: name: University of British Columbia
Year: 2021

description: Bedload transport is the movement of coarse grains through river channels by bouncing, rolling, and sliding. Because coarse grains control river stability, predicting the rate of bedload transport is a fundamental problem in river science. This problem is usually approached with continuum mechanics, but this approach is questionable considering that coarse sediment grains rarely move in densities approximating a continuum. An alternative approach describes bedload transport from the trajectories of individual grains using statistical physics. This approach has become increasingly popular in recent decades, but many fundamental issues prevent this approach from being widely adopted. In particular, the connection between individual particle trajectories and transport rates remains unclear, and particle trajectory models remain highly simplified. Feedbacks between topography and sediment transport remain challenging to analyze, and basic properties of bedload motions like downstream travel velocities remain incompletely understood. Buried particles cannot appreciably move downstream, but even this simple observation has not been comprehensively described in the statistical physics approach. This thesis presents four projects completed in my PhD which overcome these issues to provide new understanding of bedload transport from a statistical point of view. First, I demonstrate how to calculate the sediment flux from the dynamics of individual grains, and I model the trajectories of grains alternating through motion and rest having fluctuating velocities in the motion state. This links the sediment flux to the grain-scale dynamics and describes particle trajectories with additional detail compared to earlier descriptions. Second, I include feedbacks between local bed elevations and sediment transport, quantifying the interplay of bed elevation changes and sediment transport rates and predicting how long particles can stay buried in the river bed. Third, I incorporate the sediment burial process into a model of downstream sediment transport, predicting how grains move downstream when they can become buried. Finally, I describe bedload dynamics on short timescales, predicting the movement velocities of bedload particles using methods adopted from granular physics. I conclude by summarizing these developments, discussing their implications for the statistical description of bedload transport, and suggesting how we can use this modeling progress to better understand landscapes.

description: Corollary 2, Entry 9, Chapter 4 of Ramanujan's first notebook claims that a certain sum is asymptotic to ln(x) + gamma, where x is a real variable in the sum and gamma is Euler's constant. Ramanujan's claim is known to be correct for the case n = 1, but incorrect for n > 2 (here n is an integer parameter in the sum). We show that the result is correct for n = 2. We also consider the order of the error term, and discuss a different, correct generalisation of the case n = 1.

description: The real physical space is derived from a mathematical space constructed as a tessellation lattice of primary balls, or superparticles. Mathematical characteristics, such as distance, surface and volume, generate in the fractal tessellation lattice the basic physical notions (mass, particle, the particle's de Broglie wavelength and so on) and the corresponding fundamental physical laws. The submicroscopic mechanics developed in the tessellattice easily results in the conventional quantum mechanical formalism at a larger atomic scale and Newton's gravitational law at a macroscopic scale.

title: An Evaluation of the Promotion Policy of the Iron County Schools
Creators: name: Forsyth, Claudia J.
Publisher: name: Utah State University
Year: 1966

description: In 1931, the Department of Superintendents, National Education Association, in their Nineth Yearbook, put "Pupil Promotion" as first in a listing of five factors needing study . In 1966, more than three decades later, the effects of promotion or nonpromotion, still remain the subject of serious consideration among educators. The problem has been the subject of research studies and many opinion articles.
The Iron County School District, Cedar City, Utah, has advocated a policy of careful evaluation for each child considered for nonpromotion . The philosophy of the district which advocates adjusting instruction to meet individual differences should eliminate, except in rare cases, the need for nonpromotion. The policy, however, has not been accepted without opposition or argument; for there are those who feel that the sole responsibility of the school is to meet the academic needs of the child and that grade standards must be met.

Applying this characterization, the authors prove that quasiconformal mappings preserve $\dot F^s_{n/s,\,q}$ on $\rn$ for all $s\in(0,\,1)$ and $q\in(n/(n+s),\,\infty]$. A metric measure space version of the above morphism property is also established.
Time-Out Lattice Sequential Decoding for the MIMO ARQ Channel

description: The optimal diversity-multiplexing-delay tradeoff for the multi-input multi-output (MIMO) automatic repeat request (ARQ) channel can be achieved using incremental redundancy lattice space-time codes coupled with a list decoder for joint error detection and correction. Such a decoder is based on the minimum mean-square error lattice decoding principle which is implemented using sphere decoding algorithms. However, sphere decoders suffer from high computational complexity for low-to-moderate signal-to-noise ratios, especially for large signal dimensions. In this paper, we would like to construct a more efficient decoder that is capable of achieving the optimal tradeoff with much lower complexity. In particular, we will study the throughput-performance-complexity tradeoffs in sequential decoding algorithms and the effect of preprocessing and termination strategies. We show, analytically and via simulation, that using the \textit{lattice sequential decoder} that implements a time-out algorithm for joint error detection and correction, the optimal tradeoff of the MIMO ARQ channel can be achieved with significant reduction in decoding complexity.

Detailed land cover mapping in a seasonally dry tropical forest landscape using multiple sensor types
Creators: name: Dwiputra, Adrian
Publisher: name: University of British Columbia
Year: 2021

description: Detailed mapping of land cover is essential for supporting science-based sustainable landscape management. Despite the importance of land cover mapping in monitoring landscapes dynamics, land cover data are not always available. Even when the land cover data are available, they often lack detailed discrimination between forest types and plantations. This issue was found in a seasonally dry tropical forest landscape in Siem Reap and Preah Vihear, Cambodia. In this thesis, I explored the potential of (1) the fusion of optical and radar data in developing detailed land cover maps and revealing the driver of landscape change, and (2) vertical vegetation structure acquired by the Global Ecosystem Dynamics Investigation (GEDI) mission—a new mission that harnesses a space-borne waveform lidar sensor installed on the International Space Station—to improve the vegetation mapping in the studied landscape. The fusion between radar (Sentinel-1) and optical (Sentinel-2) satellite data slightly improved the land cover classification accuracy (1.6% overall accuracy increase) relative to Sentinel-2-only classification. Between 2015 and 2019, I detected a 247,781.04 Ha dry deciduous forest loss; most were due to logging (147,314 Ha). Land designations, such as the protected areas and the economic land concessions (ELCs), significantly determine land cover change. The classification of vegetation types using GEDI data had 81.9% overall accuracy despite the limited spatial coverage of GEDI data. The GEDI-only classification results could identify the seasonally inundated forests with better accuracy than the land cover map derived from the fusion of optical-radar data. These results demonstrate the potential of structural information acquired by Sentinel-1 and GEDI to improve our ability to identify vegetation types in complex, heterogeneous landscapes.

description: As this writer began preparation for the recital, many problems of performance began to manifest themselves, problems which are not encountered in opera or oratorio. First one must consider the problem of endurance . Would this singer be able to meet the demands of one full hour or recital performance?
Inasmuch as some of the compositions chosen seemed more demanding than others, it seemed advisable to alternate numbers which placed great physical stress upon the singer with those which allowed some moments of ease and relaxation. It is also necessary to consider significant periods and styles of vocal literature and choose songs and arias which are representative.
or all the vocal performing arts, recital singing may well offer the greatest challenge to singers. It is the responsibility or the singer to communicate to the audience throughout the entire performance, and this must be done without the aid of props, scenery, chorus, staging or lighting, elements that are so common to some other media or vocal performance. It then becomes apparent that it is the sole responsibility of the singer, together with a good accompanist, to keep the feeling of spontaneity and life flowing throughout the performance . Each song or aria requires a change of mood and emotion and it is often difficult for a singer to accomplish this readily.
In order to accurately represent the important forms of vocal literature , it is necessary to have singing proficiencies in a minimum of four languages: English, Italian, French and German. Each language offers a unique challenge.
One difficulty in singing English lies in the fact that each section of our country tends to develop its own peculiar inflections and accents. It is difficult to sing English songs without falling victim to one's own speech habits...

Spectra- and isochrone-fitting coupled with color indices calibration yield [Fe/H]=-0.2+-0.1. At an age of 2.65+-0.20 Gyr BG Ind is well advanced in the main-sequence evolutionary phase - in fact, its primary is at TAMS or just beyond it. Together with three similar systems (BK Peg, BW Aqr and GX Gem) it offers an interesting opportunity to test the theoretical description of overshooting in the critical mass range 1.2-1.5 Msun.

description: We consider supersymmetric shifted hybrid inflation models with a red tilted scalar spectral index n_s in agreement with the WMAP 7-yr central value. If non-minimal supergravity corrections are included, these models can also support a tensor-to-scalar ratio as large as r = 0.02, which may be observable by the Planck Satellite. In contrast to the standard supersymmetric hybrid inflation scenario, topological defects produced via gauge symmetry breaking are inflated away in the shifted version of the theory.

description: It was argued by Brigante et.al that the lower bound on the ratio of the shear viscosity to the entropy density in strongly coupled plasma is translated into microcausality violation in the dual gravitational description. Since transport properties of the system characterize its infrared dynamics, while the causality of the theory is determined by its ultraviolet behavior, the viscosity bound/microcausality link should not be applicable to theories that undergo low temperature phase transitions. We present an explicit model of AdS/CFT correspondence that confirms this fact.

description: This report contains a numerical stability analysis of factorization algorithms for computing the Cholesky decomposition of symmetric positive definite matrices of displacement rank 2. The algorithms in the class can be expressed as sequences of elementary downdating steps. The stability of the factorization algorithms follows directly from the numerical properties of algorithms for realizing elementary downdating operations. It is shown that the Bareiss algorithm for factorizing a symmetric positive definite Toeplitz matrix is in the class and hence the Bareiss algorithm is stable. Some numerical experiments that compare behavior of the Bareiss algorithm and the Levinson algorithm are presented. These experiments indicate that in general (when the reflection coefficients are not all positive) the Levinson algorithm is not stable; certainly it can give much larger residuals than the Bareiss algorithm.

description: The inclusion of such a large number and variety of songs and arias in a vocal recital necessitates a separate discussion of each composer involved and his contributions to vocal literature. Accordingly, the writer has compiled this report into sections dealing with the composers. A brief biographical sketch of each composer has been given and an analysis of the music performed in the recital has been made .
The personal translations of the writer are included with each song written in a foreign language . To a singer not familiar with the language, the meaning of a piece is as important, if not more so, as the phonetics involved, and translating the songs into English from their original settings helped the writer immensely to interpret the songs effectively.
The music presented in the recital and covered in this paper encompasses nearly all periods of musical development. The repertoiry consists of art songs and arias in German, French, Italian, and English.
Amplification and stability of magnetic fields and dynamo effect in young A stars

description: This study is concerned with the early evolution of magnetic fields and differential rotation of intermediate-mass stars which may evolve into Ap stars. We report on simulations of the interplay of differential rotation and magnetic fields, the stability limits and non-linear evolution of such configurations, and the prospects of dynamo action from the unstable cases. The axisymmetric problem delivers a balance between field amplification and back-reaction of the magnetic field on the differential rotation. The non-axisymmetric case involves also the Tayler instability of the amplified toroidal fields. We consider limits for field amplification and apply these to young A stars. Apart from its application to Ap stars, the instability is scrutinized for the fundamental possibility of a dynamo. We are not looking for a dynamo as an explanation for the Ap star phenomenon. The kinetic helicity is concentrated near the tangent cylinder of the inner sphere of the computational domain and is negative in the northern hemisphere. This appears to be a ubiquitous effect not special to the Tayler instability. The latter is actually connected with a positive current helicity in the bulk of the spherical shell giving rise to a small, but non-vanishing alpha-effect in non-linear evolution of the instability.

Towards violation of Born's rule: description of a simple experiment
Creators: name: Khrennikov, Andrei
Publisher: name: arXiv
Year: 2010
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Recently a new model with hidden variables of the wave type was elaborated, so called prequantum classical statistical field theory (PCSFT). Roughly speaking PCSFT is a classical signal theory applied to a special class of signals -- "quantum systems". PCSFT reproduces successfully all probabilistic predictions of QM, including correlations for entangled systems. This model peacefully coexists with all known no-go theorems, including Bell's theorem. In our approach QM is an approximate model. All probabilistic predictions of QM are only (quite good) approximations of "real physical averages". The latter are averages with respect to fluctuations of prequantum fields. In particular, Born's rule is only an approximate rule. More precise experiments should demonstrate its violation. We present a simple experiment which has to produce statistical data violating Born's rule. Since the PCSFT-presentation of this experiment may be difficult for experimenters, we reformulate consequences of PCSFT in terms of the conventional wave function. In general, deviation from Born's rule is rather small. We found an experiment amplifying this deviation. We start with a toy example in section 2. Then we present a more realistic example based on Gaussian states with very small dispersion, see section 3.
description: The paper was completed with the description of an experiment with Gaussian states with very small dispersion. This experiment should induce violation of Born's rule, the fundamental law of QM

Rational Periodic Sequences for the Lyness Recurrence

description: Consider the celebrated Lyness recurrence $x_{n+2}=(a+x_{n+1})/x_{n}$ with $a\in\Q$. First we prove that there exist initial conditions and values of $a$ for which it generates periodic sequences of rational numbers with prime periods $1,2,3,5,6,7,8,9,10$ or $12$ and that these are the only periods that rational sequences $\{x_n\}_n$ can have. It is known that if we restrict our attention to positive rational values of $a$ and positive rational initial conditions the only possible periods are $1,5$ and $9$. Moreover 1-periodic and 5-periodic sequences are easily obtained. We prove that for infinitely many positive values of $a,$ positive 9-period rational sequences occur. This last result is our main contribution and answers an open question left in previous works of Bastien \& Rogalski and Zeeman. We also prove that the level sets of the invariant associated to the Lyness map is a two-parameter family of elliptic curves that is a universal family of the elliptic curves with a point of order $n, n\ge5,$ including $n$ infinity. This fact implies that the Lyness map is a universal normal form for most birrational maps on elliptic curves.

description: We show that an invariant an universal length scale can be consistently introduced in a generally covariant theory through the gravitational sector using the Palatini approach. The resulting theory is able to capture different aspects of quantum gravity phenomenology in a single framework. In particular, it is found that in this theory field excitations propagating with different energy-densities perceive different background metrics, which is a fundamental characteristic of the DSR and Rainbow Gravity approaches. We illustrate these properties with a particular gravitational model and explicitly show how the {\it soccer ball problem} is avoided in this framework. The isotropic and anisotropic cosmologies of this model also avoid the big bang singularity by means of a big bounce.

Playful plates : examining the effects of food presentation on fruit and vegetable consumption in children 8-12 years of age
Creators: name: Schmidtke, Skylar
Publisher: name: University of British Columbia
Year: 2021

description: Exposure to fruits and vegetables at a young age is important for developing a healthy palate and encouraging good dietary habits later in life. Nevertheless, the responsibility of promoting positive dietary behaviours falls to the caregivers who must compete with the allure of highly-processed food items. Preliminary findings suggest that modifying fruit and vegetables to resemble fun shapes and designs can be an effective method for encouraging fruit and vegetable consumption. However, more research is needed to validate this technique in a home-based environment. The purpose of this study was to explore the effect of food modification on the consumption, mood and liking of fruits and vegetables in children. A total of 43 children between the ages of 8-12 years participated in the study. Caregivers were asked to prepare either a visually appealing or standard snack. Children in the kid-friendly condition (n = 22) consumed a visually appealing snack. Whereas children in the non-creative condition (n = 21) consumed a standard snack. Results suggest that the presentation of the snack has no influence on intake, mood and liking of fruits and vegetables in children 8-12 years of age. However, more research is needed to better understand the influence of food modification on fruit and vegetable consumption.

Sequential monitoring of response-adaptive randomized clinical trials
Creators: name: Zhu, Hongjian

Publisher: name: arXiv
Year: 2010
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: Clinical trials are complex and usually involve multiple objectives such as controlling type I error rate, increasing power to detect treatment difference, assigning more patients to better treatment, and more. In literature, both response-adaptive randomization (RAR) procedures (by changing randomization procedure sequentially) and sequential monitoring (by changing analysis procedure sequentially) have been proposed to achieve these objectives to some degree. In this paper, we propose to sequentially monitor response-adaptive randomized clinical trial and study it's properties. We prove that the sequential test statistics of the new procedure converge to a Brownian motion in distribution. Further, we show that the sequential test statistics asymptotically satisfy the canonical joint distribution defined in Jennison and Turnbull (\citeyearJT00). Therefore, type I error and other objectives can be achieved theoretically by selecting appropriate boundaries. These results open a door to sequentially monitor response-adaptive randomized clinical trials in practice. We can also observe from the simulation studies that, the proposed procedure brings together the advantages of both techniques, in dealing with power, total sample size and total failure numbers, while keeps the type I error. In addition, we illustrate the characteristics of the proposed procedure by redesigning a well-known clinical trial of maternal-infant HIV transmission.
