title: Anti-Inflammatory Properties of Xylitol in a Model of Chronic Sinus Disease
Creators: name: Thompson, Melissa
Publisher: name: Griffith University
Year: 2013
Subjects: subject: Chronic rhinosinusitis
subject: Nasal and sinus mucosa
subject: Xylitol
subject: Sinusitis

description: Background. Chronic rhinosinusitis is a highly prevalent condition estimated to affect 9% of the adult population in Australia. It is responsible for a significant burden of disease at a population level and imparts considerable morbidity and reduced quality of life to affected individuals. Recent American data has suggested an $8.6 billion annual direct healthcare cost associated with chronic rhinosinusitis. Few medical options for treating chronic rhinosinusitis exist and there is a paucity of evidence in support of a best medical treatment. Currently available treatments confer a modest benefit. The hallmark of chronic rhinosinusitis is chronic inflammation of the nasal and sinus mucosa lasting in excess of twelve weeks and resulting in typical symptoms. Chronic rhinosinusitis is a multi-factorial disease for which there are many postulated contributory factors. Although the aetiology of the disease is yet to be fully elucidated, current literature suggests the primacy of immune dysfunction in its pathogenesis and treatment recalcitrance. Characteristic inflammatory cell infiltrates and cytokine response have been identified for chronic rhinosinusitis subtypes. Inflammatory mediators with altered activity and/or expression in chronic rhinosinusitis represent potential therapeutic targets. Aims and Objectives. This study sought to investigate the anti-inflammatory and immune modulating activity of xylitol, an agent that has anecdotal utility in CRS and established antibacterial and antibiofilm actions. In order to achieve this aim inflammatory mediator targets were identified and the activity of xylitol against their production was examined relative to that of established anti-inflammatory agents. A further objective in this study was to establish a cell-based in-vitro model that best resembled the clinical condition of CRS and considered the effect of xylitol on epithelial and immune cells likely to be encountered in-vivo.

description: A new approach is suggested to quantum differential calculus on certain quantum varieties. It consists in replacing quantum de Rham complexes with differentials satisfying Leibniz rule by those which are in a sense close to Koszul complexes from \cite{G1}. We also introduce the tangent space on a quantum hyperboloid equipped with an action on the quantum function space and define the notions of quantum (pseudo)metric and quantum connection (partially defined) on it. All objects are considered from the viewpoint of flatness of quantum deformations. A problem of constructing a flatly deformed quantum gauge theory is discussed as well.

description: DC-magnetization data measured down to 40 mK speak against conventional freezing and reinstate YbMgGaO$_4$ as a triangular spin-liquid candidate. Magnetic susceptibility measured parallel and perpendicular to the $c$-axis reaches constant values below 0.1 and 0.2 K, respectively, thus indicating the presence of gapless low-energy spin excitations. We elucidate their nature in the triple-axis inelastic neutron scattering experiment that pinpoints the low-energy ($E$ $\leq$ $J_0$ $\sim$ 0.2 meV) part of the excitation continuum present at low temperatures ($T$ $$ $J_0$ that is rooted in the breaking of nearest-neighbor valence bonds and persists to temperatures well above $J_0$/$k_B$, the low-energy one originates from the rearrangement of the valence bonds and thus from the propagation of unpaired spins. We further extend this picture to herbertsmithite, the spin-liquid candidate on the kagome lattice, and argue that such a hierarchy of magnetic excitations may be a universal feature of quantum spin liquids.

Searching for the Signature of the Magnetic Fields at the Base of the Solar Convection Zone with Solar-Cycle Variations of p-Mode Travel Time
Creators: name: Chou, Dean-Yi

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We study the solar-cycle variations of solar p-mode travel time for different wave packets to probe the magnetic fields at the base of the solar convection zone. We select the wave packets which return to the same spatial point after traveling around the Sun with integral number of bounces. The change in one-bounce travel time at solar maximum relative to minimum is approximately the same for all wave packets studied except a wave packet whose lower turning point is located at the base of the convection zone. This particular wave packet has an additional decrease in travel time at solar maximum relative to other wave packets. The magnitude of the additional decrease in travel time for this particular wave packet increases with solar activity. This additional decrease in travel time might be caused by the magnetic field perturbation and sound speed perturbation at the base of the convection zone. With the assumption that this additional decrease is caused only by the magnetic field perturbation at the base of the convection zone, the field strength is estimated to be about a 4-7x10^5 gauss at solar maximum if the filling factor is unity. We also discuss the problem of this interpretation.

Zooming-in on a Lévy process: Failure to observe threshold exceedance over a dense grid

description: For a Lévy process $X$ on a finite time interval consider the probability that it exceeds some fixed threshold $x>0$ while staying below $x$ at the points of a regular grid. We establish exact asymptotic behavior of this probability as the number of grid points tends to infinity. We assume that $X$ has a zooming-in limit, which necessarily is $1/α$-self-similar Lévy process with $α\in(0,2]$, and restrict to $α>1$. Moreover, the moments of the difference of the supremum and the maximum over the grid points are analyzed and their asymptotic behavior is derived. It is also shown that the zooming-in assumption implies certain regularity properties of the ladder process, and the decay rate of the left tail of the supremum distribution is determined.

description: Vocabulary gap among children with language delays and their typically developing peers has been addressed and studied for a long time. This gap not only adversely affects developmental trajectory and future academic achievement of children, especially for those who were left behind at an early age, but also would become wider and wider when children apply their vocabulary knowledge into reading and learning. This gap change is also referred as Matthew Effect: the rich get richer and the poor get poorer. To approach a deeper understanding on how to prevent Matthew Effect and provide high quality vocabulary intervention to narrow gap, this study systematically reviewed 31 peer-reviewed studies with 159 effect sizes regarding vocabulary intervention for young children with and without language delays from preschool to first grade. Data sources included ERIC, ProQuest, PsychInfo, PubMed, and Google Scholar from 2000 to December 2018. Besides, high-ranked scholarly journals in special education were used to manually search additional references. Grounded from previous meta-analyses on vocabulary interventions, the current synthesized analyses also explored reviewed studies’ characteristics such as participants’ background, intervention type, intervention duration, intervention delivery, measurement mechanism, research design, and summary effect size. To analyze how effective and efficient the reviewed studies were to improve children’s vocabulary learning, the current study applied random effect model based meta-analysis strategies with R programming to measure the overall effect size across reviewed studies, the associations among learning outcome and research characteristics, and the learning outcome for children with and without language delays respectively. Results indicated that these interventions were moderately effective to improve children’s vocabulary knowledge including children who were having language delays. Certain instructional types and instruments were reinforced such as explicit instructions, targeted word selection, and measurement adoption. In addition, the concern regarding intervention efficiency for gap narrowing and the investigation on gap narrowing measurement were discussed. The results on efficiency suggested that future investigation and teaching implementation should continuously explore how research design, gap change measurement, and word selection could benefit gap narrowing for young children.

description: V838 Mon underwent, after a first nova-like outburst in January and a usual decline, a second outburst after one month, and a third weak one again a month later. Moreover a very small increase of the temperature at the beginning of April gives us a hint on a physical process with a period of one month. We obtained a BVRIc time sequence and modelled the photometric behaviour of the object. This leads us to the conclusion that the interstellar foreground extinction has to be 0.6 < E(B-V) < 0.8 and that the quasi-photosphere had persistently unusually low temperatures for nova-like systems. The photometry was used to follow the dramatic changes of the expansion. While the appearing 10 micron excess can be well described by the heating of material ejected during this event, the IRAS emission near the location of the progenitor, originates most likely from dust, which were formed during the previous evolution of the object. Assuming that the light echoes are coming from circumstellar material, the distance is 640 to 680 pc - smaller than the 790 pc given in Munari et al. (2002). In our opinion V838 Mon and V4332 Sgr are manifestations of a new class of eruptive variables. We do not count M31 RV to this class.

description: A series of studies have been carried out to elucidate the sediment effect on the saturation level of methane hydrate in sediments. The specimens tested covered most of the natural sediment types, with various combinations of particle size and mineral composition. The results obtained indicate that particle size and clay contents are the two key factors determining the saturation level of gas hydrate in sediments: the finer the particle size and/or the higher the clay content, the lower the hydrate saturation. The observed particle size effect and clay effect on hydrate saturation can be accredited to the specific surface area of a sediment.

description: Understanding the protein folding process is an outstanding issue in biophysics; recent developments in molecular dynamics simulation have provided insights into this phenomenon. However, the large freedom of atomic motion hinders the understanding of this process. In this study, we applied persistent homology, an emerging methods to analyze topological features in a dataset, to reveal protein folding dynamics. We developed a new method to characterize protein structure based on persistent homology and applied this method to molecular dynamics simulations of chignolin. Using principle component analysis or non-negative matrix factorization, our analysis method revealed two stable states and one saddle state, corresponding to the native, misfolded, and transition states, respectively. We also identified an unfolded state with slow dynamics in the reduced space. Our method serves as a promising tool to understand the protein folding process.

description: In this note we introduce a new model for the mailing problem in branched transportation in order to allow the cost functional to take into account the orientation of the moving particles. This gives an effective answer to [Problem 15.9] of the book "Optimal transportation networks" by Bernot, Caselles, and Morel. Moreover we define a convex relaxation in terms of rectifiable currents with group coefficients. With such approach we provide the problem with a notion of calibration. Using similar techniques we define a convex relaxation and a corresponding notion of calibration for a variant of the Steiner tree problem in which a connectedness constraint is assigned only among a certain partition of a given set of finitely many points.

Sound in virtual reality

description: Sound is a crucial part of our life. Well-designed acoustic behaviors can lead to significant improvement in both physical and virtual interactions. In computer graphics,  most existing methods focused primarily on improving the accuracy. It remained  underexplored on how to develop efficient acoustic simulation algorithms for interactive practical applications.
      The challenges arise from the dilemma between expensive accurate simulations and fast feedback demanded by intuitive user interaction: traditional physics-based acoustic simulations are computationally expensive; yet, for end users to benefit from the simulations, it is crucial to give prompt feedback during interactions.
      In this thesis, I investigate how to develop efficient acoustic simulations for real-world applications such as immersive media and digital fabrication. To address the above-mentioned challenges, I leverage precomputation and optimization to significantly improve the speed while preserving the accuracy of complex acoustic phenomena. This work discusses three efforts along this research direction: First, to ease sound designer's workflow, we developed a fast keypoint-based precomputation algorithm to enable interactive acoustic transfer values in virtual sound simulations. Second, for realistic audio editing in  360° videos, we proposed an inverse material optimization based on fast sound simulation and a hybrid ambisonic audio synthesis that exploits the directional isotropy in spatial audios. Third, we devised a modular approach to efficiently simulate and optimize fabrication-ready acoustic filters, achieving orders of magnitudes speedup while maintaining the simulation accuracy. Through this series of projects, I demonstrate a wide range of applications made possible by efficient acoustic simulations.

New examples of quasi-exactly solvable multidimensional matrix Schrödinger operators on curved manifolds are obtained by applying the above results.

Efficiency in Lung Transplant Allocation Strategies
Creators: Zou, Jingjing
Publisher: name: Columbia University
Year: 2015
Subjects: subject: Statistics
subject: FOS: Mathematics

description: Currently in the United States, lungs are allocated to transplant candidates based on the Lung Allocation Score (LAS). The LAS is an empirically derived score aimed at increasing total life span pre- and post-transplantation, for patients on lung transplant waiting lists. The goal here is to develop efficient allocation strategies in the context of lung transplantation.
      In this study, patient and organ arrivals to the waiting list are modeled as independent homogeneous Poisson processes. Patients' health status prior to allocations are modeled as evolving according to independent and identically distributed finite-state inhomogeneous Markov processes, in which death is treated as an absorbing state. The expected post-transplantation residual life is modeled as depending on time on the waiting list and on current health status. For allocation strategies satisfying certain minimal fairness requirements, the long-term limit of expected average total life exists, and is used as the standard for comparing allocation strategies.
      Via the Hamilton-Jacobi-Bellman equations, upper bounds as a function of the ratio of organ arrival rate to the patient arrival rate for the long-term expected average total life are derived, and corresponding to each upper bound is an allocable set of (state, time) pairs at which patients would be optimally transplanted. As availability of organs increases, the allocable set expands monotonically, and ranking members of the waiting list according to the availability at which they enter the allocable set provides an allocation strategy that leads to long-term expected average total life close to the upper bound.
      Simulation studies are conducted with model parameters estimated from national lung transplantation data from United Network for Organ Sharing (UNOS). Results suggest that compared to the LAS, the proposed allocation strategy could provide a 7% increase in average total life.

description: Pressure represents a clean tuning parameter for traversing the complex phase diagrams of interacting electron systems and as such has proved of key importance in the study of quantum materials. Application of controlled uniaxial pressure has recently been shown to more than double the transition temperature of the unconventional superconductor Sr$_{2}$RuO$_{4}$ for example, leading to a pronounced peak in $T_\mathrm{c}$ vs. strain whose origin is still under active debate. Here, we develop a simple and compact method to apply large uniaxial pressures passively in restricted sample environments, and utilize this to study the evolution of the electronic structure of Sr$_{2}$RuO$_{4}$ using angle-resolved photoemission. We directly visualize how uniaxial stress drives a Lifshitz transition of the $γ$-band Fermi surface, pointing to the key role of strain-tuning its associated van Hove singularity to the Fermi level in mediating the peak in $T_\mathrm{c}$. Our measurements provide stringent constraints for theoretical models of the strain-tuned electronic structure evolution of Sr$_{2}$RuO$_{4}$. More generally, our novel experimental approach opens the door to future studies of strain-tuned phase transitions not only using photoemission, but also other experimental techniques where large pressure cells or piezoelectric-based devices may be difficult to implement.

description: We study the projective linear group PGL_2(A), associated with an arbitrary algebra A, and its subgroups from the point of view of their action on the space of involutions in A. This action formally resembles Moebius transformations known from complex geometry. By specifying A to be an algebra of bounded operators in a Hilbert space H, we rediscover the Moebius group defined by Connes and study its action on the space of Fredholm modules over the algebra A. There is an induced action on the K-homology of A, which turns out to be trivial. Moreover, this action leads naturally to a simpler object, the polarized module underlying a given Fredholm module, and we discuss this relation in detail. Any polarized module can be lifted to a Fredholm module, and the set of different lifts forms a category, whose morphisms are given by generalized Moebius tranformations. We present an example of a polarized module canonically associated with the differentiable structure of a smooth manifold V. Using our lifting procedure we obtain a class of Fredholm modules characterizing the conformal structures on V. Fredholm modules obtained in this way are a special case of those constructed by Connes, Sullivan and Teleman.

description: Context: Within the field of Mining Software Repositories, there are numerous methods employed to filter datasets in order to avoid analysing low-quality projects. Unfortunately, the existing filtering methods have not kept up with the growth of existing data sources, such as GitHub, and researchers often rely on quick and dirty techniques to curate datasets. Objective: The objective of this study is to develop a method capable of filtering large quantities of software projects in a resource-efficient way. Method: This study follows the Design Science Research (DSR) methodology. The proposed method, PHANTOM, extracts five measures from Git logs. Each measure is transformed into a time-series, which is represented as a feature vector for clustering using the k-means algorithm. Results: Using the ground truth from a previous study, PHANTOM was shown to be able to rediscover the ground truth on the training dataset, and was able to identify "engineered" projects with up to 0.87 Precision and 0.94 Recall on the validation dataset. PHANTOM downloaded and processed the metadata of 1,786,601 GitHub repositories in 21.5 days using a single personal computer, which is over 33% faster than the previous study which used a computer cluster of 200 nodes. The possibility of applying the method outside of the open-source community was investigated by curating 100 repositories owned by two companies. Conclusions: It is possible to use an unsupervised approach to identify engineered projects. PHANTOM was shown to be competitive compared to the existing supervised approaches while reducing the hardware requirements by two orders of magnitude.

description: Lithium abundances in the atmospheres of the super Li-rich C-giants WZ Cas and WX Cyg are derived by the spectral synthesis technique {\bf using} the Li I resonance line at λ670.8 nm and {\bf three subordinate} lines at λλ812.6, 610.4 and 497.2 nm. The differences between the Li abundances derived from the λ670.8 nm line and the λλ497.2, 812.6 nm lines do not exceed $\pm$ 0.5 dex. The lithium line at \la610.4 nm provides typically lower abundances than the resonance line (by $\approx$ 1 dex). The mean LTE and NLTE Li abundances from three Li I lines (excluding \la610.4 nm) are 4.7, 4.9 for WZ Cas, and 4.6, 4.8 for WX Cyg, respectively.

description: Coastal structures are always facing the threat of damage caused by different wave actions. A better understanding of different seabed behaviours could effectively reduce the damage caused by waves. In this thesis, four different models (u-w-p, u-p, u and w-p) are developed to analyse the different behaviours of seabeds composed of fine granular soil (silt and normally consolidated clay) and coarse granular soil (loose sand, dense sand, and gravel). In relation to the u-w-p model, which is also the most important and comprehensive one used in this study, acceleration, velocity and displacement were considered, with the three important parameters being analysed: pore water pressure, effective stress, and shear stress. The purpose of this research was to illustrate the general behaviour of various seabeds under wave actions, and to clarify the roles of different seabed soil parameters, then to identify the probability of liquefaction and shear failure for seabed composed of different materials. The research also sought to compare the different behaviour of fine granular soil and coarse granular soil, especially via a detailed description of the behaviour of fine granular soil, and giving a wider picture of seabed response under wave actions, which has not been studied in previous research and could become an important foundation in further analysis of fine grained seabed.

Some Properties of Riesz Means and Spectral Expansions

description: It is well known that short-time expansions of heat kernels correlate to formal high-frequency expansions of spectral densities. It is also well known that the latter expansions are generally not literally true beyond the first term. However, the terms in the heat-kernel expansion correspond rigorously to quantities called Riesz means of the spectral expansion, which damp out oscillations in the spectral density at high frequencies by dint of performing an average over the density at all lower frequencies. In general, a change of variables leads to new Riesz means that contain different information from the old ones. In particular, for the standard second-order elliptic operators, Riesz means with respect to the square root of the spectral parameter correspond to terms in the asymptotics of elliptic and hyperbolic Green functions associated with the operator, and these quantities contain "nonlocal" information not contained in the usual Riesz means and their correlates in the heat kernel. Here the relationship between these two sets of Riesz means is worked out in detail; this involves just classical one-dimensional analysis and calculation, with no substantive input from spectral theory or quantum field theory. This work provides a general framework for calculations that are often carried out piecemeal (and without precise understanding of their rigorous meaning) in the physics literature.

Efficient Estimation of the Expectation of a Latent Variable in the Presence of Subject-Specific Ancillaries

Subjects: subject: Statistics

subject: Latent variables
subject: Estimation theory

description: Latent variables are often included in a model in order to capture the diversity among subjects in a population. Sometimes the distribution of these latent variables are of principle interest. In studies where sequences of observations are taken from subjects, ancillary variables, such as the number of observations provided by each subject, usually also vary between subjects. The goal here is to understand efficient estimation of the expectation of the latent variable in the presence of these subject-specific ancillaries.
      Unbiased estimation and efficient estimation of the expectation of the latent parameter depend on the dependence structure of these three subject-specific components: latent variable, sequence of observations, and ancillary. This dissertation considers estimation under two dependence configurations. In Chapter 3, efficiency is studied under the model in which no assumptions are made about the joint distribution of the latent variable and the subject-specific ancillary.  Chapter 4 treats the setting where the ancillary variable and the latent variable are independent.

Dasyatidae

description: Family Dasyatidae   Dasyatidae (stingrays) are the dominant group of rays in the coastal tropical Indo-West Pacific. While stingray taxonomy is problematic, recent revisions have vastly improved knowledge of this family (Last et al. 2016a). Dasyatidae are amongst the most commonly landed ray groups in Bangladesh, with high demand for consumption and accessories (Last et al. 2016a; Haque et al. 2018). This report identified seven species of Dasyatidae rays in addition to the 24 species previously reported in Bangladesh (Roy et al. 2015).

Integrating security policy design in the software design

description: Security is an integral part of most distributed modern software systems, but is still not considered as an explicit part in the development process. Security mechanisms and policies are generally added to existing systems as an afterthought, with all the problems of unsatisfied security requirements, integration difficulties and mismatches between running system and the design models. We propose to integrate the design of application-oriented access control policies early into the system’s development process. The standard language for modeling the design of systems the Unified Modeling Language (UML), is used to specify access control policies. Within the integration we will develop extensions of the UML model support the automatic generation and verification of a access control policy to configure a distributed component- based for view-based access control.

description: It is shown that Einstein-Weyl (EW) equations in 2+1 dimensions contain the dispersionless Kadomtsev-Petviashvili (dKP) equation as a special case: If an EW structure admits a constant weighted vector then it is locally given by $h=d y^2-4d xd t-4ud t^2, ν=-4u_xd t$, where $u=u(x, y, t)$ satisfies the dKP equation $(u_t-uu_x)_x=u_{yy}$. Linearised solutions to the dKP equation are shown to give rise to four-dimensional anti-self-dual conformal structures with symmetries. All four-dimensional hyper-Kähler metrics in signature $(++--)$ for which the self-dual part of the derivative of a Killing vector is null arise by this construction. Two new classes of examples of EW metrics which depend on one arbitrary function of one variable are given, and characterised. A Lax representation of the EW condition is found and used to show that all EW spaces arise as symmetry reductions of hyper-Hermitian metrics in four dimensions. The EW equations are reformulated in terms of a simple and closed two-form on the $\CP^1$-bundle over a Weyl space. It is proved that complex solutions to the dKP equations, modulo a certain coordinate freedom, are in a one-to-one correspondence with minitwistor spaces (two-dimensional complex manifolds ${\cal Z}$ containing a rational curve with normal bundle $Ø(2)$) that admit a section of $κ^{-1/4}$, where $κ$ is the canonical bundle of ${\cal Z}$. Real solutions are obtained if the minitwistor space also admits an anti-holomorphic involution with fixed points together with a rational curve and section of $κ^{-1/4}$ that are invariant under the involution.
