description: We address the linear-mode analysis performed near an equilibrium configuration in the fluid rest frame with a dynamical magnetic field perturbed on a constant configuration. We develop a simple and general algorithm for an analytic solution search that works on an order-by-order basis in the derivative expansion. This method can be applied to general sets of hydrodynamic equations. Applying our method to the first-order relativistic magnetohydrodynamics, we demonstrate that the method finds a complete set of solutions. We obtain two sets of analytic solutions for the four and two coupled modes with seven dissipative transport coefficients. The former set has been missing in the literature for a long time due to the difficulties originating from coupled degrees of freedom and strong anisotropy provided by a magnetic field. The newly developed method resolves these difficulties. We also find that the small-momentum expansions of the solutions break down when the momentum direction is nearly perpendicular to an equilibrium magnetic field due to the presence of another small quantity, that is, a trigonometric function representing the anisotropy. We elaborate on the angle dependence of the solutions and provide alternative series representations that work near the right angle. This identifies the origin of a discrepancy found in recent works. Finally, we discuss the issues of causality and stability based on our analytic solutions and recent developments in the literature.

description: For $m,n\in\mathbb{N}$, let $f_{m,n}(x)=\bigr[ψ^{(m)}(x)\bigl]^2+ψ^{(n)}(x)$ on $(0,\infty)$. In the present paper, we prove using two methods that, among all $f_{m,n}(x)$ for $m,n\in\mathbb{N}$, only $f_{1,2}(x)$ is nontrivially completely monotonic on $(0,\infty)$. Accurately, the functions $f_{1,2}(x)$ and $f_{m,2n-1}(x)$ are completely monotonic on $(0,\infty)$, but the functions $f_{m,2n}(x)$ for $(m,n)\ne(1,1)$ are not monotonic and does not keep the same sign on $(0,\infty)$.

description: We investigate the failed partial eruption of a filament system in NOAA AR 12104 on 2014 July 5, using multiwavelength EUV, magnetogram, and H$α$ observations, as well as magnetic field modeling. The filament system consists of two almost co-spatial segments with different end points, both resembling a C shape. Following an ejection and a precursor flare related to flux cancellation, only the upper segment rises and then displays a prominent twisted structure, while rolling over toward its footpoints. The lower segment remains undisturbed, indicating that the system possesses a double-decker structure. The erupted segment ends up with a reverse-C shape, with material draining toward its footpoints, while losing its twist. Using the flux rope insertion method, we construct a model of the source region that qualitatively reproduces key elements of the observed evolution. At the eruption onset, the model consists of a flux rope atop a flux bundle with negligible twist, which is consistent with the observational interpretation that the filament possesses a double-decker structure. The flux rope reaches the critical height of the torus instability during its initial relaxation, while the lower flux bundle remains in stable equilibrium. The eruption terminates when the flux rope reaches a dome-shaped quasi-separatrix layer that is reminiscent of a magnetic fan surface, although no magnetic null is found. The flux rope is destroyed by reconnection with the confining overlying flux above the dome, transferring its twist in the process.

description: The field of contrast-enhanced ultrasound (CEUS) combines nonlinear, resonant microbubbles (MBs) with dedicated pulse sequences to reveal the vascular function of organs. Clinical ultrasound contrast agents consist of polydisperse MB suspensions with diameters ranging from 0.5 to 10 um and resonance frequencies ranging from 1 to 15 MHz. As a result, just a small fraction of MBs resonates at a given ultrasound frequency. MB suspensions with narrow size distributions can be tuned for a specific imaging frequency, boost CEUS sensitivity and enable deeper vascular imaging. However, their enhanced nonlinear behavior makes imaging susceptible to nonlinear wave propagation artifacts. Here, we numerically investigate the impact of the acoustic wavefront shape on the imaging of nonlinear, monodisperse MBs. Specifically, our approach relies on an extension of the Iterative Nonlinear Contrast Source (INCS) method that accounts for all nonlinear effects in CEUS. We demonstrate that supersonic x-shaped wavefronts referred to as x-waves can be used to generate ultrasound images of monodisperse MBs without nonlinear wave propagation artifacts. On the contrary, imaging based on focused, planar and diverging wavefronts leads to significant nonlinear artifacts. Taken together, our results show that x-waves can harness the full potential of monodisperse MBs by enabling their sensitive and specific detection in a tissue context.

title: RNA structure and function signals in a novel Nidovirus sequence from the Sea Hare Aplaysia californica
Creators: name: Bukhari, Khulud Ibrahim
Publisher: name: University of Reading
Year: 2019

description: Nidoviruses are enveloped, positive stranded RNA viruses that are among the most complex plus-strand RNA viruses known. My work has discovered the sequence of a new, highly divergent virus, tentatively named Abyssovirus, in a pool of sequenced intracellular RNA from a metazoan. Based on comparison of the genomic organization and replicase subunits, Abyssovirus appears to belong to a new family of nidoviruses. The aim of the present project was to validate the sequence data by studying the function of the predicted unusual translational stop-start signal located in the replicase gene, and to express predicted viral proteases and test their catalytic activity in Sf9 insect cells, E. coli and mammalian expression systems. The translational stop-start signal was found to allow ribosomes to readthrough the natural stop codon in the expression systems tested. Additionally, Abyssovirus Main Protease (MPro) showed evidence of cleavage of fragments from both ends of the expressed protease, as is typical for polyprotein-embedded Nidovirus proteases. These results suggest that the Abyssovirus RNA sequence encodes biologically functional proteins, and therefore that the RNA sequence likely does represent an extant virus with some Nidovirus-like features and an Abyssovirus-specific mechanism to translate the second half of the replicase open reading frame.
title: The effect of thermal denaturation on whey protein derived mouthdrying and investigations into mucoadhesion as a mechanism of action
Creators: name: Bull, Stephanie
Publisher: name: University of Reading
Year: 2019

description: Whey protein is a functional ingredient used in sports nutrition and in the prevention of sarcopenia in older adults. Non-compliance of whey protein fortified beverages in clinical settings can be due to negative sensory attributes, such as a drying sensation. The mechanism of whey protein derived mouthdrying is yet to be fully defined, with a focus on low pH beverages in the literature. This study aimed to: investigate the effect of thermal denaturation on the build up of drying elicited by neutral pH whey protein concentrate (WPC); determine potential mechanisms; and mitigate drying. This research investigated the sensory properties of four WPC aqueous samples heated for varying lengths of time using two sensory techniques; quantitative descriptive analysis and sequential profiling. Heating time was found to correlate with higher drying, mouthcoating and chalky intensities, with an increase over repeated consumption and a high persistence of sensation seen for all samples. Heated samples had a larger particle size, which could contribute to the increase in drying observed. The physical build-up of WPC in the mouth was measured using an in vivo retention method, which found the most heated sample had the highest retention up to 60 s after the sample had been swallowed. Accessible thiol concentration was seen to increase with heating time, which could lead to interactions with the mucosa, and consequently a higher oral retention. Interactions of WPC with mucin were observed using particle size analysis and spectroscopic analysis; however, interactions were not observed for individual whey proteins, indicating that the complex mix of WPC contributes to the interactions. Polysaccharides were used in an attempt to mitigate drying by blocking mucoadhesive interactions and lubricating the mouth. Although the mitigation of drying was unsuccessful, a reduction in other mouthfeel attributes was observed suggests this is an area requiring further research. The thesis concludes that both particle size and protein structure are implicated in whey protein derived mouthdrying, supporting the proposal of a mucoadhesive mechanism.

The Tactics of Community Organizations in the Environmental Justice Movement

Subjects: subject: Community organization
subject: Enviromental justice

description: Community organizations aim to create positive change surrounding public health and environmental policies, but which tactics are most successful? In my research I used archival and media materials to analyze two court cases brought by an environmental justice organization against a refinery expansion in California. In one court case, the organization created a coalition of like-minded organizations, which both increased their resources and allowed them to better utilize scientific research to articulate a legitimate argument against expansion, leading to a legal victory. In the other case, the organization did not partner with any other nonprofits and had less overall support from the community leading to a decrease in effectiveness and ultimately a settlement agreement. These findings suggest that community organization litigation may be most effective when organizations partner with other nonprofits, especially those with similar long-term goals.

Dependence of solar wind power spectra on the direction of the local mean magnetic field

Publisher: name: arXiv
Year: 2009
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: (Abridged) Wavelet analysis can be used to measure the power spectrum of solar wind fluctuations along a line in any direction with respect to the local mean magnetic field. This technique is applied to study solar wind turbulence in high-speed streams in the ecliptic plane near solar minimum using magnetic field measurements with a cadence of eight vectors per second. The analysis of nine high-speed streams shows that the reduced spectrum of magnetic field fluctuations (trace power) is approximately azimuthally symmetric about B_0 in both the inertial range and dissipation range; in the inertial range the spectra are characterized by a power-law exponent that changes continuously from 1.6 \pm 0.1 in the direction perpendicular to the mean field to 2.0 \pm 0.1 in the direction parallel to the mean field. The large uncertainties suggest that the perpendicular power-law indices 3/2 and 5/3 are both consistent with the data. The results are similar to those found by Horbury et al. (2008) at high heliographic latitudes.

description: Observations of the ß Cephei star 12 Lacertae have been made at both high time and spectral resolution with an Image Isocon television camera. The observations cover complete cycles of the pulsation on two consecutive nights in October 1972. The spectral region covered includes the two Si III inclines at λ 4553 and λ 4568. The line profile variations have been studied in detail; in particular the line doubling at certain phases of the pulsation. Wavelength shifts of the separate components were measured and a discontinuous radial velocity curve was obtained.

description: Non-equilibrium fluctuation theorems (NFTs) relate work performed on a system as its Hamiltonian varies with time, to equilibrium data of the initial and final states. In a classical context the system energy can be directly measured, while a quantum implementation requires the incorporation of a work-agent. We demonstrate that the uncertainty principle imposes inherent quantum limitations on the applicability of the NFT for probing non-trivial mesoscopic systems. We work out the NFT validity regime for the simplest quantum-dot toy model, and discuss future applications.

Growth of British Columbian native Indian children as assessed from anthropometric measurements
Creators: name: Rabeneck, Sonya
Publisher: name: University of British Columbia
Year: 2010

description: A cross-sectional growth study was designed to obtain information on the growth patterns of British Columbian Native Indian children. The object of the study was to establish whether growth patterns of B.C. Native Indian children living in student residences correspond to those of non-Indian reference children. The study sample consisted of all children 6 to 17 years attending the six student residences administered by the Department of Indian and Northern Affairs. The total sample size was 734 children, representing 77 reserves in the province. Standing height, sitting height, weight, arm circumference, four skinfold thicknesses (triceps, subscapular, biceps and suprailiac), and head circumference were measured according to the recommendations of the International Biological Program (Weiner and Lourie, 1969). Arm muscle diameter, circumference and area were derived according to the method of Frisancho (1974). Individual findings were plotted, as scatter diagrams against standard reference curves, data for which was obtained from Caucasian children. Results indicate a considerable growth deficit in standing and sitting height in younger children which appears to be somewhat corrected by adolescence. Weight measurements, although falling predominantly below the Iowa mean, generally reflect adequate gain with age. Arm measurements indicate well maintained musculature throughout the age-range studied, with relatively low degrees of triceps adipose tissue. Head circumference displays an initial deficit in younger children which is largely corrected by adolescence. It was concluded that protein nutritional status of B.C. Native Indian children living in student residences may be relatively better than calorie nutritional status.

description: We have studied the adsorption of Li atoms at the hollow sites of graphene nanoribbons (zigzag and armchair), graphene, and fullerenes by means of density functional theory calculations including local and semilocal functionals. The binding energy of a Li atom on armchair nanoribbons (of about 1.70 eV for LSDA and 1.20 eV for PBE) is comparable to the corresponding value in graphene (1.55 and 1.04 eV for LSDA and PBE, respectively). Notably, the interaction between Li and zigzag nanoribbons is much stronger. The binding energy of Li at the edges of zigzag nanoribbons is about 50% stronger than in graphene for the functionals studied here. While the charge transfer between the Li adatom and the zigzag nanoribbon significantly affects the magnetic properties of the latter providing an additional interaction mechanism that is not present in two-dimensional graphene or armchair nanoribbons, we find that the morphology of the edges, rather than magnetism, is responsible for the enhanced Li-nanoribbon interaction.

description: A few nearby interacting galaxies are known that host elevated number of ultraluminous X-ray sources. Here we report the results of a multiwavelength study of the X-ray source population in the field of the interacting pair of galaxies NGC5774/NGC5775. A total of 49 discrete sources are detected, including 12 ultraluminous X-ray source candidates. X-ray source positions are mapped onto optical and radio images to search for potential counterparts. Twelve sources in the field have optical counterparts. Optical colors are used to differentiate these sources, which are mostly located outside the optical extent of the interacting galaxies, as potential globular clusters (2), one compact blue dwarf galaxy and quasars (5). We obtained optical spectra of two of the latter, which confirm that they are background quasars. We expect 3 background sources in the field of these two galaxies. These results are used to determine the true X-ray population of these two interacting galaxies, which are connected with two bridges. Two high mass X-ray binaries are detected on these two bridges suggesting their formation through the interaction-induced starformation episode.

description: The method of dimensional recurrences proposed by one of the authors [1,2] is applied to the evaluation of the pentagon-type scalar integral with on-shell external legs and massless internal lines. For the first time, an analytic result valid for arbitrary space-time dimension d and five arbitrary kinematic variables is presented. An explicit expression in terms of the Appell hypergeometric function F_3 and the Gauss hypergeometric function_2F_1, both admitting one-fold integral representations, is given. In the case when one kinematic variable vanishes, the integral reduces to a combination of Gauss hypergeometric functions_2F_1. For the case when one scalar invariant is large compared to the others, the asymptotic values of the integral in terms of Gauss hypergeometric functions_2F_1 are presented in d = 2 - 2 epsilon, 4 - 2 epsilon, and 6 - 2 epsilon dimensions. For multi-Regge kinematics, the asymptotic value of the integral in d = 4 - 2 epsilon dimensions is given in terms of the Appell function F_3 and the Gauss hypergeometric function_2F_1.

description: The advent of blockchain technology has led to a massive wave of different decentralized ledger technology (DLT) solutions. Such projects as Bitcoin and Ethereum have shifted the paradigm of how to transact value in a decentralized manner, but their various core technologies have their own advantages and disadvantages. This paper aims to describe an alternative to modern decentralized financial networks by introducing the Humanode network. Humanode is a network safeguarded by cryptographically secure bio-authorized nodes. Users will be able to deploy nodes by staking their encrypted biometric data. This approach can potentially lead to the creation of a public, permissionless financial network based on consensus between equal human nodes with algorithm-based emission mechanisms targeting real value growth and proportional emission. Humanode combines different technological stacks to achieve a decentralized, secure, scalable, efficient, consistent, immutable, and sustainable financial network: 1) a bio-authorization module based on cryptographically secure neural networks for the private classification of 3D templates of users' faces 2) a private Liveness detection mechanism for identification of real human beings 3) a Substrate module as a blockchain layer 4) a cost-based fee system 5) a Vortex decentralized autonomous organization (DAO) governing system 6) a monetary policy and algorithm, Fath, where monetary supply reacts to real value growth and emission is proportional. All of these implemented technologies have nuances that are crucial for the integrity of the network. In this paper we address these details, describing problems that might occur and their possible solutions. The main goal of Humanode is to create a stable and just financial network that relies on the existence of human life.
Codimension-3 Singularities and Yukawa Couplings in F-theory

description: F-theory is one of the frameworks where all the Yukawa couplings of grand unified theories are generated and their computation is possible. The Yukawa couplings of charged matter multiplets are supposed to be generated around codimension-3 singularity points of a base complex 3-fold, and that has been confirmed for the simplest type of codimension-3 singularities in recent studies. However, the geometry of F-theory compactifications is much more complicated. For a generic F-theory compactification, such issues as flux configuration around the codimension-3 singularities, field-theory formulation of the local geometry and behavior of zero-mode wavefunctions have virtually never been addressed before. We address all these issues in this article, and further discuss nature of Yukawa couplings generated at such singularities. In order to calculate the Yukawa couplings of low-energy effective theory, however, the local descriptions of wavefunctions on complex surfaces and a global characterization of zero-modes over a complex curve have to be combined together. We found the relation between them by re-examining how chiral charged matters are characterized in F-theory compactification. An intrinsic definition of spectral surfaces in F-theory turns out to be the key concept. As a biproduct, we found a new way to understand the Heterotic--F theory duality, which improves the precision of existing duality map associated with codimension-3 singularities.

description: We prove a uniqueness theorem for the charged Nariai black holes and ultracold black holes in four dimensions. In particular, we show that an analytic solution to four-dimensional Einstein-Maxwell theory with a positive cosmological constant containing a static extremal Killing horizon with spherical cross-sections of large radius (compared to the cosmological scale), must be locally isometric to the extremal Reissner-Nordström-de Sitter black hole or its near-horizon geometry. The theorem generalises to extremal static horizons with small radius, establishing uniqueness of cold black holes for generic values of the radius.

description: We formulate a holographic description of effects of disorder in conformal field theories based on the replica method and the AdS/CFT correspondence. Starting with $n$ copies of conformal field theories, randomness with a gaussian distribution is described by a deformation of double trace operators. After computing physical quantities, we take the $n \to 0$ limit at the final step. We compute correlation functions in the disordered systems by using the holographic replica method as well as the formulation in the conformal field theory. We find examples where disorder changes drastically the scaling of two point functions. The renormalization group flow of the effective central charge in our disordered systems is also discussed.

Generic metrics and the mass endomorphism on spin three-manifolds

description: Let $(M,g)$ be a closed Riemannian spin manifold. The constant term in the expansion of the Green function for the Dirac operator at a fixed point $p\in M$ is called the mass endomorphism in $p$ associated to the metric $g$ due to an analogy to the mass in the Yamabe problem. We show that the mass endomorphism of a generic metric on a three-dimensional spin manifold is nonzero. This implies a strict inequality which can be used to avoid bubbling-off phenomena in conformal spin geometry.

description: This paper is the second part of a series of studies discussing a novel attitude determination method for nano-satellites. Our approach is based on the utilization of thermal imaging sensors to determine the direction of the Sun and the nadir with respect to the satellite with sub-degree accuracy. The proposed method is planned to be applied during the Cubesats Applied for MEasuring and LOcalising Transients (CAMELOT) mission aimed at detecting and localizing gamma-ray bursts with an efficiency and accuracy comparable to large gamma-ray space observatories. In this paper we introduce a simulation model aimed at testing the applicability of our attitude determination approach. Its first part simulates the orbit and rotation of a satellite with arbitrary initial conditions while its second part applies our attitude determination algorithm which is based on a multiplicative extended Kalman filter. The simulated satellite is assumed to be equipped with a GPS system, MEMS gyroscopes and the infrasensors. These instruments provide the required data input for the Kalman filter. We demonstrate the applicability of our attitude determination algorithm by simulating the motion of a nano-satellite on Low Earth Orbit. Our results show that the attitude determination may have a 1$σ$ error of $\sim30'$ even with a large gyroscope drift during the orbital periods when the infrasensors provide both the direction of the Sun and the Earth (the nadir). This accuracy is an improvement on the point source detection accuracy of the infrasensors. However, the attitude determination error can get as high as 25$^{\circ}$ during periods when the Sun is occulted by the Earth. We show that following an occultation period the attitude information is immediately recovered by the Kalman filter once the Sun is observed again.

description: We study the semiclassical spectrum of excitations around a long spinning string in AdS_3. In addition to the usual small fluctuations, we find the spectrum contains a branch of solitonic excitations of finite energy. We determine the dispersion relation for these excitations. This has a relativistic form at low energies but also matches the dispersion relation for the "hole" of the dual gauge theory spin chain at high energies. The low-energy behaviour is consistent with the hypothesis that the solitonic excitations studied here are continuously related to the elementary excitations of the string.

description: We study the chaotic behavior of the Gibbs state of spin-glasses under the application of an external magnetic field, in the crossover region where the field intensity scales proportional to $1/\sqrt{N}$, being $N$ the system size. We show that Replica Symmetry Breaking (RSB) theory provides universal predictions for chaotic behavior: they depend only on the zero-field overlap probability function $P(q)$ and are independent of other features of the system. Using solely $P(q)$ as input we can analytically predict quantitatively the statistics of the states in a small field. In the infinite volume limit, each spin-glass sample is characterized by an infinite number of states that have a tree-like structure. We generate the corresponding probability distribution through efficient sampling using a representation based on the Bolthausen-Sznitman coalescent. In this way, we can compute quantitatively properties in the presence of a magnetic field in the crossover region, the overlap probability distribution in the presence of a small field and the degree of decorrelation as the field is increased. To test our computations, we have simulated the Bethe lattice spin glass and the 4D Edwards-Anderson model, finding in both cases excellent agreement with the universal predictions.

Intersecting branes and Nambu$-$Jona-Lasinio model

description: We discuss chiral symmetry breaking in the intersecting brane model of Sakai and Sugimoto at weak coupling for a generic value of separation $L$ between the flavour $D8$ and anti-$D8$-branes. For any finite value of the radius $R$ of the circle around which the colour $D4$-branes wrap, a non-local Nambu$-$Jona-Lasinio (NJL) type short-range interaction couples the flavour branes and anti-branes. We argue that chiral symmetry is broken in this model only above a certain critical value of the 4-dimensional 't Hooft coupling and confirm this through numerical calculations of solutions to the gap equation. We also numerically investigate chiral symmetry breaking in the limit $R \to \infty$ keeping $L$ fixed, but find that simple ways of implementing this limit do not lead to a consistent picture of chiral symmetry breaking in the non-compact version of the non-local NJL model.

description: Gravitational radiation is properly defined only at future null infinity ($\scri$), but in practice it is estimated from data calculated at a finite radius. We have used characteristic extraction to calculate gravitational radiation at $\scri$ for the inspiral and merger of two equal mass non-spinning black holes. Thus we have determined the first unambiguous merger waveforms for this problem. The implementation is general purpose, and can be applied to calculate the gravitational radiation, at $\scri$, given data at a finite radius calculated in another computation.
