On the density of Banach {$C(K)$} spaces with the Grothendieck property

Subjects: subject: Functional Analysis (math.FA)

description: Using the method of forcing we prove that consistently there is a Banach space of continuous functions on a compact Hausdorff space with the Grothendieck property and with density less than the continuum. It follows that the classical result stating that ``no nontrivial complemented subspace of a Grothendieck $C(K)$ space is separable'' cannot be strengthened by replacing ``is separable'' by ``has density less than that of $l_\infty$'', without using an additional set-theoretic assumption. Such a strengthening was proved by Haydon, Levy and Odell, assuming Martin's axiom and the negation of the continuum hypothesis. Moreover, our example shows that certain separation properties of Boolean algebras are quite far from the Grothendieck property.

description: Background: Short-chain fatty acids (SCFAs), including propionic acid (PA), are key in immunological research. Supplementing PA has shown benefits for autoimmune diseases. A comprehensive understanding of the PA pharmacokinetics is essential for the optimal design and execution of studies utilizing orally administered PA. Objective: We propose two methods of measuring PA in serum, carried out by different laboratories. Design: Blood samples from 20 volunteers were collected hourly following PA supplementation. Methods: Serum propionate quantification was performed with two independent mass spectrometry-based (MS) analyses, including liquid-chromatography (LC)-MS and direct-infusion (DI)-MS. Results: PA levels increased within 1 h of ingestion of 500 mg PA. Serum concentrations ranged from 1.3 to 4.5 µmol/L, rising significantly after 1 h (p < 0.05). Serum levels returned to baseline within 2 h. No significant differences were found regarding sex or diet. Conclusion: The shown pharmacokinetics can be used in future PA research.

description: Studying stellar pulsations in open clusters offers the possibility to perform ensemble asteroseismology. The reasonable assumption that the cluster members have the same age, distance, and overall metallicity aids in the seismic modelling process and tightly constrains it. Therefore it is important to identify open clusters with many pulsators. New pulsating stars of the Beta Cephei type were searched for among the members of the open cluster NGC 637. Thirty-one hours of time resolved V filter CCD photometry were obtained. The measurements confirmed two previously known variables, and revealed three new Beta Cephei stars plus one more candidate. All four pulsators have amplitudes high enough for easy mode identification and are multiperiodic. With four certain pulsating members, NGC 637 is now among the six open clusters richest in Beta Cephei stars. It is thus an excellent target for ensemble asteroseismology, and to tackle the question what separates pulsating from apparently constant stars in the Beta Cephei domain.

description: Controlled environment agriculture (CEA) is a practice of food production under optimized conditions to intensify production yield, and thus has potential for addressing food security for a growing population. Aquaculture and aquaponics are two types of CEA that can produce aquatic animals along with plants using non-arable lands and lower inputs of water and nutrients. However, their operations have high energy consumption and generate considerable nutrient-rich sludge and wastewater, making their environmental performance an emerging research focus. This thesis quantitively analyzed the environmental sustainability of aquaponics and aquaculture production using life cycle assessment (LCA).The LCA on aquaponics evaluated a marine aquaponics production system that grew shrimp, red orache, minutina and okahajiki, and analyzed the effect of salinity, C/N ratio, and shrimp-to-plant stocking density. The grow-out stage accounted for over 90% of total environmental impacts with electricity use as the predominant contributor. The marine aquaponic production exhibited best environmental performance when operated at low salinity (10 ppt), and high C/N ratio (15) and stocking density (5:1), which can be further improved by 95–99% via the use of wind power as electricity source. Additionally, variation in the prices of aquaponic products was found to improve the system’s environmental impacts by up to 8%.The aquaculture LCA focused on shrimp recirculating aquaculture systems (RAS) and evaluated the environmental feasibility of microalgae-based wastewater treatment. Microalgae treatment effectively removed 74% of phosphate in RAS wastewater and thus reduced the freshwater eutrophication potential by 55%. However, its remediation performance was inferior to activated sludge treatment due to different operation scales. Electricity was the principal hotspot of microalgae treatment and made up over 99% of all the environmental impacts, which can be considerably decreased by reducing coal use in the electricity supply. Three utilization pathways for algal biomass (feed ingredient, biodiesel and biogas) were investigated; however, only biogas production was found to show environmental benefits to marine eutrophication remediation owing to the low biomass quantity produced.While aquaculture and aquaponics play important roles in meeting the globally growing demand for seafood, this thesis provides valuable life cycle inventory data for these fields. Moreover, the LCA models developed in this thesis are useful decision-making tools for aquaculture and aquaponic producers to adapt farming practices with lower environmental footprint.

Tests were performed to determine the dark rate, charge and timing resolutions, double-pulsing rate, and desired operating voltage for each tube, so that the tubes could be sorted for optimal placement in the detector. Seven phototubes were tested to find the angular dependence of their response. After the Super-K phototube implosion accident, an analysis was performed to determine the risk of a similar accident with MiniBooNE.

description: Activation of the epidermal growth factor (EGF) receptor regulates many processes associated with metastasis,including modulation of cell:cell and cell:substrate interactions,production of matrix-degrading proteinases,and cellular migration. We have demonstrated previously that EGF stimulates migration and matrix metalloproteinase (MMP)-9-dependent invasion of ovarian cancer cells. In this study,we compare the roles of EGF-induced phosphatidylinositol 3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) activities in regulation of cellular responses associated with ovarian tumor cell metastasis. Inhibition of PI3K and MAPK activity impairs EGF-stimulated cell migration,in vitro invasion,and MMP-9 production. PI3K activity is not required for growth factor disruption of cell:cell junctions,whereas inhibitors of extracellular signal-regulated kinase (ERK)1/ERK2 activation and p38 MAPK activity block EGF-dependent junction dissolution. EGF promotes pro-MMP-9 binding to the cell surface through a mechanism that is independent of extracellular enzyme concentration. Interestingly,inhibition of PI3K activity abolishes EGF-induced cell surface association of pro-MMP-9,whereas inhibitors of MAPKs only partially block the response. These data suggest that EGF receptor activation promotes a PI3K-dependent induction of a cell surface pro-MMP-9 binding component that may facilitate gelatinase-mediated cellular invasion and supports an expanded role for elevated PI3K activity in cellular responses associated with ovarian tumor metastasis. In addition,our findings support the hypothesis that divergent kinase activities regulate distinct cellular events associated with growth factor-induced invasion of ovarian cancer cells.
The functional significance of plasma-accessible carbonic anhydrase for cardiovascular oxygen transport in teleosts
Creators: name: Harter, Till S.
Publisher: name: University of British Columbia
Year: 2018

description: A novel mechanism has recently been discovered in rainbow trout that allows these fish to enhance the partial pressure of O₂ (PO₂) in their muscles. Teleosts have evolved highly pH-sensitive haemoglobins (Hb), where an arterial-venous pH shift (ΔpHa-v) can severely reduce Hb-O₂ binding affinity. Most teleosts create large ΔpHa-v by actively regulating the intracellular (pHi) of their red blood cells (RBC) through adrenergically stimulated sodium-proton exchangers (β-NHE). This creates H⁺ gradients across the RBC membrane that are short-circuited in the presence of plasma-accessible carbonic anhydrase (paCA) at the tissues, to greatly enhance O₂ unloading from pH-sensitive Hb. Thus, I hypothesised that teleosts increase the O₂ capacitance of their blood (βb) by a mechanism of active RBC pHi regulation that is modulated through a heterogeneous distribution of paCA, which has functional significance for O₂ transport in vivo. Mechanistically, I discovered that in rainbow trout, the time-course of β-NHE short-circuiting in the capillaries and the recovery of RBC pHi during venous transit, are consistent with a system that can enhance O₂ unloading at the tissues with every pass through the circulation. Functionally, I discovered that the inhibition of paCA in Atlantic salmon swimming at a low speed or at rest, required a compensatory increase in cardiac output of ~30%, corroborating a role of paCA in O₂ transport over a broad range of conditions. Further, I discovered paCA in the heart lumen of coho salmon; thus, also cardiac O₂ supply in salmonids may rely on β-NHE short-circuiting. In teleosts, the evolution of β-NHE short-circuiting required the loss of paCA at the gills. However, in Antarctic icefish, I propose that the loss of Hb and RBCs released the functional constraint on the expression of paCA at the gills, and allowed for the enzyme to catalyse CO₂ excretion in the absence of RBC CA. Collectively, my findings indicate that an active mechanism at the level of the RBC enhances βb and is an integral part of the salmonid mode of cardiovascular O₂ transport, and perhaps most teleosts, with important implications for the physiology, the conservation and the evolutionary history, of nearly half of all vertebrates.

description: The statistical mechanics of phase transitions in dense systems of polydisperse particles presents distinctive challenges to computer simulation and analytical theory alike. The core difficulty, namely dealing correctly with particle size fractionation between coexisting phases, is set out in the context of a critique of previous simulation work on such systems. Specialized Monte Carlo simulation techniques and moment free energy method calculations, capable of treating fractionation exactly, are then described and deployed to study the fluid-solid transition of an assembly of repulsive spherical particles described by a top-hat "parent" distribution of particle sizes. The cloud curve delineating the solid-fluid coexistence region is mapped as a function of the degree of polydispersity $δ$, and the properties of the incipient "shadow" phases are presented. The coexistence region is found to shift to higher densities as $δ$ increases, but does not exhibit the sharp narrowing predicted by many theories and some simulations.

description: We derive the finite-temperature quantum-tunneling rate from first principles. The rate depends on both real- and imaginary-time; we demonstrate that the relevant instantons should therefore be defined on a Schwinger-Keldysh contour, and how the familiar Euclidean-time result arises from it in the limit of large physical times. We generalize previous results for general initial states, and identify distinct behavior in the high- and low-temperature limits, incorporating effects from background fields. We construct a consistent perturbative scheme that incorporates large finite-temperature effects.

description: Meteoritic data, especially regarding chondrules and calcium-rich, aluminum-rich inclusions (CAIs), and isotopic evidence for short-lived radionuclides (SLRs) in the solar nebula, potentially can constrain how planetary systems form. Intepretation of these data demands an astrophysical model, and the "X-wind" model of Shu et al. (1996) and collaborators has been advanced to explain the origin of chondrules, CAIs and SLRs. It posits that chondrules and CAIs were thermally processed < 0.1 AU from the protostar, then flung by a magnetocentrifugal outflow to the 2-3 AU region to be incorporated into chondrites. Here we critically examine key assumptions and predictions of the X-wind model. We find a number of internal inconsistencies: theory and observation show no solid material exists at 0.1 AU; particles at 0.1 AU cannot escape being accreted into the star; particles at 0.1 AU will collide at speeds high enough to destroy them; thermal sputtering will prevent growth of particles; and launching of particles in magnetocentrifugal outflows is not modeled, and may not be possible. We also identify a number of incorrect predictions of the X-wind model: the oxygen fugacity where CAIs form is orders of magnitude too oxidizing; chondrule cooling rates are orders of magnitude lower than those experienced by barred olivine chondrules; chondrule-matrix complementarity is not predicted; and the SLRs are not produced in their observed proportions. We conclude that the X-wind model is not relevant to chondrule and CAI formation and SLR production. We discuss more plausible models for chondrule and CAI formation and SLR production.

Regenerative block empirical likelihood for Markov chains

Year: 2011
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: Empirical likelihood is a powerful semi-parametric method increasingly investigated in the literature. However, most authors essentially focus on an i.i.d. setting. In the case of dependent data, the classical empirical likelihood method cannot be directly applied on the data but rather on blocks of consecutive data catching the dependence structure. Generalization of empirical likelihood based on the construction of blocks of increasing nonrandom length have been proposed for time series satisfying mixing conditions. Following some recent developments in the bootstrap literature, we propose a generalization for a large class of Markov chains, based on small blocks of various lengths. Our approach makes use of the regenerative structure of Markov chains, which allows us to construct blocks which are almost independent (independent in the atomic case). We obtain the asymptotic validity of the method for positive recurrent Markov chains and present some simulation results.

description: Colored tensor models have been recently shown to admit a large N expansion, whose leading order encodes a sum over a class of colored triangulations of the D-sphere. The present paper investigates in details this leading order. We show that the relevant triangulations proliferate like a species of colored trees. The leading order is therefore summable and exhibits a critical behavior, independent of the dimension. A continuum limit is reached by tuning the coupling constant to its critical value while inserting an infinite number of pairs of D-simplices glued together in a specific way. We argue that the dominant triangulations are branched polymers.

description: We have measured neutron diffraction patterns in a single crystal sample of the pyrochlore compound Er$_2$Ti$_2$O$_7$ in the antiferromagnetic phase (T=0.3\,K), as a function of the magnetic field, up to 6\,T, applied along the [110] direction. We determine all the characteristics of the magnetic structure throughout the quantum critical point at $H_c$=2\,T. As a main result, all Er moments align along the field at $H_c$ and their values reach a minimum. Using a four-sublattice self-consistent calculation, we show that the evolution of the magnetic structure and the value of the critical field are rather well reproduced using the same anisotropic exchange tensor as that accounting for the local paramagnetic susceptibility. In contrast, an isotropic exchange tensor does not match the moment variations through the critical point. The model also accounts semi-quantitatively for other experimental data previously measured, such as the field dependence of the heat capacity, energy of the dispersionless inelastic modes and transition temperature.

title: Available potential energy in axisymmetric tropical cyclones
Creators: name: Harris, Bethan Laura
Publisher: name: University of Reading
Year: 2023

description: Tropical cyclone (TC) intensification is challenging to represent in numerical models because it results from complex interactions between multi-scale processes, some of which are poorly understood. This thesis investigates TC development in an idealised axisymmetric model in terms of moist Available Potential Energy (APE) density, and suggests how diagnostics based on moist APE budgets could be applied to forecasting and global climate models to study the links between model parameterisations and the intensity of TCs. The first full budget of moist APE density for the atmosphere in any context is constructed for the axisymmetric model, using the model’s initial environmental sounding as a reference state. The main source of moist APE relative to the environment is the surface latent heat flux occurring in the low-level radial inflow. This APE is then transported inwards and converted into kinetic energy in the eyewall. The budget also reveals that APE density can be discontinuous in time and space in the moist atmosphere if air parcels possess multiple levels of neutral buoyancy, in which case a reservoir of latent APE may exist. The best APE reference state for predicting the domain-integrated rate of kinetic energy generation in a TC is shown to be a vortex in thermal wind balance. Surface fluxes are still the chief source of APE when this reference state is used. Precipitation and subgrid mixing also contribute to the kinetic energy generation. The intensification of TCs in the model, in terms of total power dissipation, is associated with an increase in the efficiency with which surface fluxes generate moist APE, even when the WISHE feedback is cut off so that the surface fluxes themselves do not increase. A two-part WISHE-efficiency feedback is proposed to drive intensification. It is also demonstrated that moist local available energetics can be used to derive a theory of potential intensity
Parallel solution to multi-scale, multi-dimensional coupled DEM-PBM model for high shear granulation using high performance computing

Publisher: name: No Publisher Supplied
Year: 2019

description: Particulate processes are prevalent in the pharmaceutical industry but, the physics underlying‎ these processes are complicated. The particle-level models used to describe these systems require large amounts of computation to solve which makes simulations slow. Another approach to model these systems is less accurate‎ bulk model which does not capture all the particle level data but is more efficient to simulate and requires lesser computational power. A quicker and a more accurate way to model such systems is to use a multi-scale model ‎i.e. use the particle-scale data into a bulk model. Using a coupled model does not decrease the time taken by each individual component of the simulation, thus there is also a need to increase the speed of the separate simulations.In this work, a unidirectional multi-scale model‎ was used to model the high shear wet granulation process. A multi-dimensional population balance‎ model (PBM) was developed with a mechanistic kernel, which obtained‎ collision data from the discrete element modeling (DEM) simulation. The PBM was run in parallel‎ using MPI + OMP hybrid technique. The DEM simulations were performed on LIGGGHTS, which‎ runs in parallel using MPI. Speedup of about 14 times was obtained for the PBM simulations‎ and around 12 for the DEM simulations. This coupling was performed using the radical pilot‎ for scaling studies from 1 to 128 cores for the PBM and up to 256 cores for the DEM. A further improvement to the PBM code was also done by developing a code in CUDA C++ such that it could utilize up to 1024 cores on the NVIDIA graphical processor units (GPU). Using‎ this developed framework, the granulation process has been modeled accurately much faster than‎ existing approaches in literature

description: Processes such as the solar wind sputtering and micrometeorite impacts can modify optical properties of surfaces of airless bodies. This explains why spectra of the main belt asteroids, exposed to these `space weathering' processes over eons, do not match the laboratory spectra of ordinary chondrite (OC) meteorites. In contrast, an important fraction of Near Earth Asteroids (NEAs), defined as Q-types in the asteroid taxonomy, display spectral attributes that are a good match to OCs. Here we study the possibility that the Q-type NEAs underwent recent encounters with the terrestrial planets and that the tidal gravity (or other effects) during these encounters exposed fresh OC material on the surface (thus giving it the Q-type spectral properties). We used numerical integrations to determine the statistics of encounters of NEAs to planets. The results were used to calculate the fraction and orbital distribution of Q-type asteroids expected in the model as a function of the space weathering timescale, t_sw (see main text for definition), and maximum distance, r*, at which planetary encounters can reset the surface. We found that t_sw ~ 1e6 yr (at 1 AU) and r* ~ 5 R_pl, where R_pl is the planetary radius, best fit the data. Values t_sw < 1e5 yr would require that r* > 20 R_pl, which is probably implausible because these very distant encounters should be irrelevant. Also, the fraction of Q-type NEAs would be probably much larger than the one observed if t_sw > 1e7 yr. We found that t_sw ~ q^2, where q is the perihelion distance, expected if the solar wind sputtering controls t_sw, provides a better match to the orbital distribution of Q-type NEAs than models with fixed t_sw. We also discuss how the Earth magnetosphere and radiation effects such as YORP can influence the spectral properties of NEAs.

description: Luminous blue variable (LBV) stars are very massive, luminous, unstable stars that suffer frequent eruptions. In the last few years, these stars have been proposed as the direct progenitors of some core-collapse supernovae (SNe), particularly Type IIn SNe, in conflict with stellar evolution theory. In this paper we investigate various scenarios wherein LBV stars have been suggested as the immediate progenitors of SNe. Many of these suggestions stem from the fact that the SNe appear to be expanding in a high density medium, which has been interpreted as resulting from a wind with a high mass-loss rate. Others arise due to perceived similarities between the SN characteristics and those of LBVs. Only in the case of SN 2005gl do we find a valid possibility for an LBV-like progenitor. Other scenarios encounter various levels of difficulty. The evidence that points to LBVs as direct core-collapse SNe progenitors is far from convincing. High mass-loss rates are often deduced by making assumptions regarding the wind parameters, which are contradicted by the results themselves. A high density need not necessarily imply a high wind mass-loss rate: wind shocks sweeping up the surrounding medium may give a high density shell with a low associated wind mass-loss rate. High densities may also arise due to wind clumps, or due to a previous LBV phase before the SN explodes as a Wolf-Rayet star. Some Type IIn SNe appear to signify more a phase in the life of a SN than a class of SNe, and may arise from more than one type of progenitor. A Wolf-Rayet phase that lasts for a few thousand years or less could be one of the more probable progenitors of Type IIns, and channels for creating short-lived W-R phases are briefly discussed.

description: This is a brief history of my experience with nanopore sequencing over the past [almost] five years, where I talk about things that have inspired me to keep playing around with the MinION, despite its somewhat quirky behaviour. It's amazing to see that the MinION was performing well, almost right from the start.
Social resilience in children with ADHD : buffers of externalizing behaviour, internalizing behaviour, and negative parenting
Creators: name: Jia, Rui Mary

description: Research shows that children with Attention-Deficit Hyperactivity Disorder (ADHD) commonly experience a myriad of social problems. Previous investigations have mainly focused on examining the risk factors for poor social functioning such as the presence of comorbid behaviour problems and negative parenting. Few studies have considered processes which may contribute to social resilience in this population. The present study investigated not only risk factors (i.e., externalizing behaviour, internalizing behaviour, negative parenting), but also compensatory/protective factors (i.e., positive teacher-child relationship quality, parent social competence) associated with social functioning in children with ADHD. The sample consisted of 233 families of children with ADHD (162 boys, 71 girls; age 5 to 12) from Vancouver and Ottawa, Canada, who were seeking assessment and treatment. Parents and teachers reported on children’s behaviour problems and social functioning. Parents also reported on their own social competence and parenting, while teachers reported on their relationship quality with the children in the study. All data were collected at one time point. Results indicated that: (a) comorbid child behaviour problems were associated with poorer social competence; (b) positive teacher-child relationship quality and parent social competence were associated with better social functioning; (c) and parent social competence buffers the risk of comorbid child externalizing behaviour on poor social competence. Additional exploratory analyses were conducted to examine both positive and negative constructs in parenting, parent social competence, and teacher-child relationship quality, and how may they relate differently to child social functioning.

The three graces in the Tits--Kantor--Koecher category

description: A metaphor of Loday describes Lie, associative, and commutative associative algebras as ``the three graces'' of the operad theory. In this article, we study the three graces in the category of $\mathfrak{sl}_2$-modules that are sums of copies of the trivial and the adjoint representation. That category is not symmetric monoidal, and so one cannot apply the wealth of results available for algebras over operads. Motivated by a recent conjecture of the second author and Mathieu, we embark on the exploration of the extent to which that category ``pretends'' to be symmetric monoidal. To that end, we examine various homological properties of free associative algebras and free associative commutative algebras, and study the Lie subalgebra generated by the generators of the free associative algebra.

Isotope effects in high-Tc cuprate superconductors: Ultimate proof for bipolaron theory of superconductivity

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

description: Developing a theory of high-temperature superconductivity in copper oxides is one of the outstanding problems in physics. Twenty-five years after its discovery, no consensus on the microscopic theory has been reached despite tremendous theoretical and experimental efforts. Attempts to understand this problem are hindered by the subtle interplay among a few mechanisms and the presence of several nearly degenerate and competing phases in these systems. Here we provide unified parameter-free explanation of the observed oxygen-isotope effects on the critical temperature, the magnetic-field penetration depth, and on the normal-state pseudogap for underdoped cuprate superconductors within the framework of the bipolaron theory compatible with the strong Coulomb and Froehlich interactions, and with many other independent observations in these highly polarizable doped insulators. Remarkably, we also quantitatively explain measured critical temperatures and magnitudes of the magnetic-field penetration depth. The present work thus represents an ultimate proof of the bipolaron theory of high-temperature superconductivity, which takes into account essential Coulomb and electron-phonon interactions.

description: In this paper, we discuss a new iterative method for computing $\sin_{p}$. This function was introduced by Lindqvist in connection with the unidimensional nonlinear Dirichlet eigenvalue problem for the $p$-Laplacian. The iterative technique was inspired by the inverse power method in finite dimensional linear algebra and is competitive with other methods available in the literature.

description: We strengthen the property $Δ$ of a function $f:[ω_2]^2\rightarrow [ω_2]^{\leq ω}$ considered by Baumgartner and Shelah. This allows us to consider new types of amalgamations in the forcing used by Rabus, Juhász and Soukup to construct thin-very tall compact scattered spaces. We consistently obtain spaces $K$ as above where $K^n$ is hereditarily separable for each $n\in\N$. This serves as a counterexample concerning cardinal functions on compact spaces as well as having some applications in Banach spaces: the Banach space $C(K)$ is an Asplund space of density $\aleph_2$ which has no Fréchet smooth renorming, nor an uncountable biorthogonal system.

Energy Spectrum Of Nonthermal Electrons Accelerated At A Plane Shock

description: We calculate the energy spectra of cosmic ray (CR) protons and electrons at a plane shock with quasi-parallel magnetic fields, using time-dependent, diffusive shock acceleration (DSA) simulations, including energy losses via synchrotron emission and Inverse Compton (IC) scattering. A thermal leakage injection model and a Bohm type diffusion coefficient are adopted. The electron spectrum at the shock becomes steady after the DSA energy gains balance the synchrotron/IC losses, and it cuts off at the equilibrium momentum p_{eq}. In the postshock region the cutoff momentum of the electron spectrum decreases with the distance from the shock due to the energy losses and the thickness of the spatial distribution of electrons scales as p^{-1}. Thus the slope of the downstream integrated spectrum steepens by one power of p for p_{br}
