description: It has been suggested by Groot Nibbelink and Pospelov that Lorentz invariance can be an emergent symmetry of low-energy physics provided the theory enjoys a non-relativistic version of supersymmetry. We construct a model that realizes the latter symmetry dynamically: it breaks Lorentz invariance but leaves the supersymmetry generators intact. The model is a supersymmetric extension of the dynamical aether theory of Jacobson and Mattingly. It shows rich dynamics and possesses a family of inequivalent vacua realizing different symmetry breaking patterns. In particular, we find stable vacua that break spontaneously spatial isotropy. Supersymmetry breaking terms give masses to fermionic and bosonic partners of the aether field. We comment on the coupling of the model to supergravity and on the implications for Horava gravity.

description: This thesis examines certain aspects of Stoney verbal morphology and phonology. Chapter I presents a morphological sketch of the language and Chapter II consists of a taxonomic classification of the verbal prefixes and suffices. Although the affixes exhibit relatively little phonological and morphological variation, one of the prefix categories exhibits a great deal. This category has been examined in detail in Chapter III and it is hypothesized that the possessive prefix gi-, the benefactive prefix giji-, and the reflexive prefix ici- are all derived from the same underlying source, #ki#, through application of rules such as “Palatalization,” "Reduplication," "Tri-Syllabic Reduction," and "Reflexive Syllable Deletion." Reduplication itself is examined in Chapter IV. It is shown that an underlying monosyllabic form must be postulated to account for reduplication of some disyllabic surface forms. The phonological process of "Consonant Cluster Devoicing" and "Coronal Dissimilation" are also discussed in relation to the process of reduplication.
Measure-driven impulsive systems : stabilization, optimal control and applications
Creators: name: Code, Warren Joseph
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation studies various standard facets of nonlinear control problems in the impulsive setting, using a framework of measure-driven systems. Containing a Borel measure in their dynamics, these systems model significant time scale discrepancies; the measure may weight actions at instants, producing trajectories that mix discrete and continuous dynamics on the "fast" and "slow" time scales, respectively. A central feature of our work is the careful use of a time reparametrization to transform these systems into standard, non-impulsive ones, so that the wealth of recent results in nonlinear control may be applied. Closed-loop stabilization of impulsive control systems containing a measure in the dynamics is addressed. It is proved that, as for regular affine systems, an almost everywhere continuous stabilizing impulsive feedback control law exists for such impulsive systems. An example illustrating the loop closing features is also presented. Necessary conditions for optimal control have recently been developed in the non-convex case by Clarke and Vinter, among others. We extend these results to generalized differential inclusions where a signed, vector-valued measure appears. In particular, we offer a set of stratified necessary conditions in optimal control of measure-driven systems, as well as a set of standard (global) conditions under weak regularity hypotheses on the differential inclusion maps. An auxiliary result essential to our proof extends existing free end-time necessary conditions results to Clarke's stratified framework. We work in the context of pseudo-Lipschitz multifunctions, which provide localized Lipschitz-like properties in the absence of convexity. We take a well-evolved solution concept framework in new directions, introducing a workable system of state-dependent measures and measure-based constraints, such as a forced impulse schedule, a restriction to purely discrete impulse dynamics or a state-dependent impulse restriction, and prove necessary conditions in optimal control for this new framework. This is an important step in the renewed use of measure-driven systems in modeling a broad range of applications within a familiar, mathematically sound framework. Taken together, these results span a broad range of topics in nonlinear, state-space control in the impulsive context, and refresh the measure-driven framework, paving the way for future research and further value in applications.
Regulation of thymic T cell progenitor importation
Creators: name: Gossens, Klaus Paul
Publisher: name: University of British Columbia
Year: 2010

description: The thymus does not contain self-renewing T cell progenitors (TCP) and therefore requires continuous importation of progenitors from the blood to sustain T cell production. Recruitment of TCP to the thymus is facilitated by a multistep adhesion cascade initiated by the interaction of PSGL-1 expressed on TCP with P-selectin expressed on thymic endothelium. Thymic TCP importation is not a steady state process but is a periodic, gated event thought to be regulated by a negative feedback signal dependent on the occupation status of intrathymic TCP niches. However the nature of this feedback mechanism remains enigmatic. The aim of this study is to analyze the underlying mechanism that control thymic TCP importation in a temporal and quantitative manner. The study is based on the hypothesis that ingress of TCP into the thymus is controlled by the regulated expression of key molecules within the thymic adhesion cascade. Indeed, the first set of data shows that Pselectin and CCL25 expression correlate with thymic receptivity. Furthermore, this study finds that P-selectin and CCL25 are periodically expressed in thymic tissues indicating that they are essential parts of the thymic gate-keeping-mechanism. Absence of the P-selectin on thymic endothelial cells or functional P-selectin ligands on TCP significantly reduces the numbers of the earliest intrathymic TCP population and abolishes periodic expression of Pselectin and CCL25 suggesting that niche occupancy plays a role in regulating the periodicity of thymic TCP importation. The study further shows that the size of the peripheral lymphocyte pool directly affects thymic P-selectin expression and TCP receptivity indicating that extrathymic factors also control thymic receptivity. As a feedback signal that could mediate changes in the peripheral lymphocyte pool into altered thymic TCP receptivity sphingosine-1-phosphate (S1P) was identified. These findings suggest a model whereby thymic TCP importation is controlled by both early thymic niche occupancy and the peripheral lymphocyte pool via S1P.

description: The history of oil in Canada began in the cormnunities of Oil Springs, Petrolia and Sarnia Ontario in the mid 1800's. The men who learned their trade there, developed the "Canadian rig" for oil drilling and were in demand in United States and in other parts of the world. John Lineman is credited with bringing in the first oil well in Alberta at Cameron Creek in 1902 and William Aldridge was the first to put the seepages in Waterton-Oil City, Pincher Creek area to commercial use. In 1890 natural gas had been discovered in Medicine Hat when Canadian Pacific Railway men were drilling for coal. In 1909, Eugene Coste founder of Canadian Western Natural Gas Company Ltd., Calgary, brought in Bow Island No. 1 well, and gasification of southern Alberta towns slowly followed. Oil in Turner Valley, Dingman No. 1, followed in 1914, and not since the Gold Rush to the Klondike was there such excitement in Western Canada. The boom was short-lived due to the First Great War. Following the Turner Valley 1914 discovery there were ten barren years before Royalite found the Mississipian discovery and twelve more before Turner Valley uncovered the deep-seated oil column. Eleven more barren years and Imperial Oil's one hundred and thirty-three dry holes followed before they were rewarded with the discovery of Leduc, in 1947. In 1938 the Oil and Gas Conservation Act of Alberta was passed to control production of oil and waste of natural gas, and the Petroleum and Natural Gas Conservation Board was set up. In 1971 the name was changed to the Energy Resources Conservation Board. It holds an unique position today with wide powers under the Act which established it, involving good drilling and production practises.

description: The current data tends to be more complex than conventional data and need dimension reduction. Dimension reduction is important in cluster analysis and creates a smaller data in volume and has the same analytical results as the original representation. A clustering process needs data reduction to obtain an efficient processing time while clustering and mitigate curse of dimensionality. This paper proposes a model for extracting multidimensional data clustering of health database. We implemented four dimension reduction techniques such as Singular Value Decomposition (SVD), Principal Component Analysis (PCA), Self Organizing Map (SOM) and FastICA. The results show that dimension reductions significantly reduce dimension and shorten processing time and also increased performance of cluster in several health datasets.

description: We have conducted a series of numerical experiments with the spherically symmetric, general relativistic, neutrino radiation hydrodynamics code Agile-BOLTZTRAN to examine the effects of several approximations used in multidimensional core-collapse supernova simulations. Our code permits us to examine the effects of these approximations quantitatively by removing, or substituting for, the pieces of supernova physics of interest. These approximations include: (1) using Newtonian versus general relativistic gravity, hydrodynamics, and transport; (2) using a reduced set of weak interactions, including the omission of non-isoenergetic neutrino scattering, versus the current state-of-the-art; and (3) omitting the velocity-dependent terms, or observer corrections, from the neutrino Boltzmann kinetic equation. We demonstrate that each of these changes has noticeable effects on the outcomes of our simulations. Of these, we find that the omission of observer corrections is particularly detrimental to the potential for neutrino-driven explosions and exhibits a failure to conserve lepton number. Finally, we discuss the impact of these results on our understanding of current, and the requirements for future, multidimensional models.

description: The barnacles included in the superfamily Coronuloidea are epizoic symbionts of various marine vertebrates (including cetaceans, sirenians, and sea turtles) and other crustaceans (crabs and horseshoe crabs). Among Coronuloidea, the so-called turtle barnacles (Chelonibiidae) are known from Paleogene times, whereas the whale barnacles (Coronulidae) likely appeared in the late Pliocene (Piacenzian). Although a derivation from the turtle barnacles (and especially from the genus Chelonibia) has been proposed, the evolutionary origin of Coronulidae remains to date obscure. In this work we reappraise a fossil record from upper Pliocene (Piacenzian) marine deposits at Casenuove (Empoli municipality, Tuscany, Italy) comprising various shells of Chelonibia testudinaria associated to a partial skeleton of a balaenid mysticete. Based on taphonomic and morpho-functional considerations, we discuss the hypothesis that the barnacles were hosted on the baleen whale, possibly on its callosities, which could have represented an analogous of the horny carapace of marine turtles. This record strongly suggests that the baleen whales can be added to the list of the possible hosts of the barnacles of the genus Chelonibia, thus hinting that the whale barnacles may have evolved from an ancient phase of dispersal of Chelonibia (or a similar ancestor) on mysticete cetaceans.

description: Exogenous ketone monoesters can raise blood β-OHB and lower glucose without other nutritional modifications or invasive procedures. However, unpleasant taste and potential gastrointestinal discomfort may make adherence to supplementation challenging. Two novel ketone supplements promise an improved consumer experience but differ in their chemical properties; it is currently unknown how these affect blood β-OHB and blood glucose compared to the ketone monoester. In a double-blind randomized cross-over pilot study, N=12 healthy individuals (29 ± 5 years, BMI = 25 ± 4 kg/m2, 42% female) participated in three experimental trials with a different ketone supplement providing 10 grams of active ingredient in each; (i) the monoester (R)-3-hydroxybutyl (R)-3-hydroxybutyrate, (ii) D-β-hydroxybutyric acid with R-1,3-butanediol, and (iii) R-1,3-butanediol. Blood β-OHB and glucose were measured via finger prick capillary blood samples at baseline and across 240 minutes post-supplementation. Supplement acceptability, hunger, and gastrointestinal distress were assessed via questionnaires. β-OHB was elevated compared to baseline in all conditions. Total and incremental area under the curve (p < 0.05) and peak β-OHB (p < 0.001) differed between conditions with highest values seen in the ketone monoester condition. Blood glucose was reduced after consumption of each supplement, with no differences in total and incremental area under the curve across supplements. Supplement acceptability was greatest for D-β-hydroxybutyric acid with R-1,3-butanediol, with no effect on hunger or evidence of gastrointestinal distress across all supplements. All ketone supplements tested raised β-OHB with highest values seen after ketone monoester ingestion. Blood glucose was lowered similarly across the assessed time frame with all three supplements.

description: We present the FOXSI (Focusing Optics X-ray Solar Imager) small explorer (SMEX) concept, a mission dedicated to studying particle acceleration and energy release on the Sun. FOXSI is designed as a 3-axis stabilized spacecraft in low-Earth orbit making use of state-of-the-art grazing incidence focusing optics combined with pixelated solid-state detectors, allowing for direct imaging of solar X-rays. The current design being studied features multiple telescopes with a 14 meter focal length enabled by a deployable boom. FOXSI will observe the Sun in the 3-80 keV energy range. The FOXSI imaging concept has already been tested on two sounding rocket flights, in 2012 and 2014 and on the HEROES balloon payload flight in 2013. FOXSI will image the Sun with an angular resolution of 8'', a spectral resolution of 0.8 keV, and sub-second temporal resolution. FOXSI is a direct imaging spectrometer with high dynamic range and sensitivity and will provide a brand-new perspective on energy release on the Sun. We describe the mission and its science objectives.

description: Given the difficulty in directly determining prominence physical parameters from observations, prominence seismology stands as an alternative method to probe the nature of these structures. We show recent examples of the application of magnetohydrodynamic (MHD) seismology techniques to infer physical parameters in prominence plasmas. They are based on the application of inversion techniques using observed periods, damping times, and plasma flow speeds of prominence thread oscillations. The contribution of Hinode to the subject has been of central importance. We show an example based on data obtained with Hinode's Solar Optical Telescope. Observations show an active region limb prominence, composed by a myriad of thin horizontal threads that flow following a path parallel to the photosphere and display synchronous vertical oscillations. The coexistence of waves and flows can be firmly established. By making use of an interpretation based on transverse MHD kink oscillations, a seismological analysis of this event is performed. It is shown that the combination of high quality Hinode observations and proper theoretical models allows flows and waves to become two useful characteristics for our understanding of the nature of solar prominences.

On the Testing of Seismicity Models

description: Recently a likelihood-based methodology has been developed by the Collaboratory for the Study of Earthquake Predictability (CSEP) with a view to testing and ranking seismicity models. We analyze this approach from the standpoint of possible applications to hazard analysis. We arrive at the conclusion that model testing can be made more efficient by focusing on some integral characteristics of the seismicity distribution. This is achieved either in the likelihood framework but with economical and physically reasonable coarsening of the phase space or by choosing a suitable measure of closeness between empirical and model seismicity rate in this space.

description: Repositories are a vital tool in modern information management and a key component of preserÂ­vation and long-term availability. They are not well-suited, however, to the current chalÂ­lenges posed by our information-rich society and the multitude of stakeholders involved in the modern scholarly publishing system. Strengthening repositories and standardizing preservaÂ­tion processes are critically important. This challenge will require not only leading multiÂ­ple stakeholder groups but also reforming multiple information systems, architectures, phiÂ­losophies, practices, and more.
OSI2016 Workgroup Question
Are we satisfied with the current state of global knowledge preservation? What are the currentÂ­ preservation methods? Who are the actors? Is this system satisfactory? What role do instituÂ­tional repositories play in this process? What does the future hold for these repositories (taking into account linking efforts, publishing company concerns about revenue declines, wideÂ­spread dark archiving practices, and so on)? Would new mandates help (or do we simply need to tighten existing mandates so they actually compel authors to do certain things)? And how do versions of record figure into all of thisâ€”that is, how do archiving poliÂ­cies (with regard to differences between pre-journal and post-journal versions) affect knowledge accuracÂ­yÂ­ and transfer? How can digital preservation advance open scholarship?

description: About twenty years ago, Choptuik studied numerically the gravitational collapse (Einstein field equations) of a massless scalar field in spherical symmetry, and found strong evidence for a universal, self-similar solution at the threshold of black hole formation. We prove rigorously the existence of a real analytic solution, that we interpret as the solution observed by Choptuik. Our construction covers an open neighborhood of the past light cone of the singularity. The proof is computer assisted. Starting from an explicit approximate solution, we show that nearby there is a true solution. The source code and a high precision data file (about 80 significant decimal digits, with rigorous error bounds) are included. We do not study perturbations.

description: While Research Information continues to mature as an area of expertise, discussions regarding the implementation and adoption of standardisation initiatives, such as CASRAI and CERIF, have intensified. Possessing the capacity to use a standard does not obligate its adoption, so the extent to which standards are employed varies across use cases and institutions, in a way that is difficult to qualify and determine. We are presenting a light-weight visualisation framework for presenting, comparing and improving the adoption of research information standards for research institutions. The framework is implemented for providing insight into identifier adoption at the University of Cambridge. The tool is easy to deploy and implement, and the insights it generates are intended to express clearly the extent to which Research Information standards have been adopted. Furthermore, the framework can be used to make this adoption knowledge available as linked open data held at a local level, reducing the need for costly metastudies and helping the standardisation community to monitor and focus standardisation development.

description: This study investigated the effects of chlorella supplementation on submaximal endurance, time trial performance, lactate threshold, and power indices during a repeated sprint performance test by fourteen male trained cyclists. Participants ingested 6 g/day of chlorella or placebo for 21-days in a double-blinded randomized counter-balanced cross-over design, with a fourteen-day washout period between trials. Each completed a 2-day testing period comprising a 1-hour submaximal endurance test at 55% external power output max and a 16.1 km time trial (Day-1), followed by a lactate threshold (Dmax) and repeated sprint performance tests (3 X 20 s sprints interspersed by 4-mins) (Day-2). Heart rate (b.min−1), RER, V̇O2 (ml·kg−1·min−1), lactate and glucose (mmol/L), time (secs), power output (W/kg), and hemoglobin (g/L) were compared across conditions. Following chlorella supplementation (chlorella vs. placebo for each measurement) average lactate and heart rate were significantly lower (p < 0.05) during submaximal endurance tests (1.68 ± 0.50 mmol/L vs. 1.91 ± 0.65 mmol/L & 138 ± 11b.min−1 vs. 144 ± 10b.min−1), average power and peak power (W/kg) were significantly higher during repeated sprint bouts (9.5 ± 0.7 W/kg vs. 9.0 ± 0.7 W/kg & 12.0 ± 1.2 W/kg vs. 11.4 ± 1.4 W/kg), hemoglobin significantly increased (149.1 ± 10.3 g/L) in comparison to placebo (143.4 ± 8.7 g/L) (p = 0.05). No differences existed between conditions for all oxygen consumption values, 16.1 km time trial measures and lactate threshold tests (p > 0.05). In conclusion, chlorella may pose as an additional supplement for cyclists to consider, particularly for those cyclists who want to improve their sprinting.

A normative account of risk
Creators: name: Ahmad, Rana Amber
Publisher: name: University of British Columbia
Year: 2010

description: Risks, even though familiar, are in fact more complicated than might first seem. To call something a risk is to describe potentially harmful events in the world. However, sometimes we mean to do more than merely describe the chance of harm occurring. To call something a risk is to also mean that some action ought to be taken to avoid it. By providing reasons for action, risk can also be a source of normative force. There are therefore two senses of risk, the descriptive and the prescriptive, yet it is often the case that only the descriptive sense is recognized. Many technical views, such as those of risk analysts or scientists assume that risks are objective matters of fact, however it is assumed that what counts as harmful includes a limited range of events such as illness, injury or death. Criticisms from other disciplines such as the social sciences and psychology have challenged the narrowly construed technical views and argued that in fact, it is difficult to distinguish what is harmful, tolerable or desirable. Incorporating these concerns I argue that a more encompassing definition of risk is the chance of some harm occurring, where harm is understood to be whatever negatively affects something of value to someone. This thesis will provide an account of normative risk by first placing it in historical context to explain how this definition of risk emerges. I will then provide an argument against the idea that risk is an objective matter of fact, and thus an ontological categorization, in favour of the view that it is subjective harm is a matter of evaluation. Following this, I then propose that risk is weakly normative in a similar way to morality. Finally I argue that when risk is understood as what might negatively affect something of value, and since a single situation might involve a threat to different values at the same time, it might be the case that different actions are prescribed.

description: The most powerful explosions on the Sun [...] drive the most severe space-weather storms. Proxy records of flare energies based on SEPs in principle may offer the longest time base to study infrequent large events. We conclude that one suggested proxy, nitrate concentrations in polar ice cores, does not map reliably to SEP events. Concentrations of select radionuclides measured in natural archives may prove useful in extending the time interval of direct observations up to ten millennia, but as their calibration to solar flare fluences depends on multiple poorly known properties and processes, these proxies cannot presently be used to help determine the flare energy frequency distribution. Being thus limited to the use of direct flare observations, we evaluate the probabilities of large-energy solar explosions by combining solar flare observations with an ensemble of stellar flare observations. We conclude that solar flare energies form a relatively smooth distribution from small events to large flares, while flares on magnetically-active, young Sun-like stars have energies and frequencies markedly in excess of strong solar flares, even after an empirical scaling with the mean activity level of these stars. In order to empirically quantify the frequency of uncommonly large solar flares extensive surveys of stars of near-solar age need to be obtained, such as is feasible with the Kepler satellite. Because the likelihood of flares larger than approximately X30 remains empirically unconstrained, we present indirect arguments, based on records of sunspots and on statistical arguments, that solar flares in the past four centuries have likely not substantially exceeded the level of the largest flares observed in the space era, and that there is at most about a 10% chance of a flare larger than about X30 in the next 30 years.

description: Losses in superconducting planar resonators are presently assumed to predominantly arise from surface-oxide dissipation, due to experimental losses varying with choice of materials. We model and simulate the magnitude of the loss from interface surfaces in the resonator, and investigate the dependence on power, resonator geometry, and dimensions. Surprisingly, the dominant surface loss is found to arise from the metal-substrate and substrate-air interfaces. This result will be useful in guiding device optimization, even with conventional materials.

description: In dieser Arbeit wird die Herstellung von monolithischem, gleichförmigem nanoporösem Palladium über einen elektrochemischen Ein-Schritt-Prozess des Entlegierens von Kupfer-Palladium-Legierungen in Schwefelsäure entwickelt und etabliert. An diesem neuartigen Material werden mechanische Reaktionen wie Ausdehnung und Elastizitätsvariationen durch elektrochemisch kontrollierte Wasserstoffaufnahme mittels in-situ Dilatometrie und in-situ dynamisch mechanischer Analyse untersucht. Die Änderung des experimentell ermittelten Elastizitätsmoduls von nanoporösem Palladium unter Wasserstoffbeladung stimmt hervorragend mit den Vorhersagen der Larché-Cahn Theorie der Elastizität offener Systeme überein.
description: This thesis establishes the synthesis of monolithic, uniform nanoporous palladium via a single-step electrochemical dealloying of copper-palladium alloys in sulfuric acid. With this nanoporous palladium material, mechanical responses such as large strain and elasticity variations through electrochemically controlled hydrogen sorption are explored by in-situ dilatometry and in-situ dynamic mechanical analysis. The variation of experimentally measured Young’s modulus of nanoporous palladium with hydrogen content agrees well with prediction by Larché-Cahn open-system elasticity theory.

description: The rapid, irreversible change of the photospheric magnetic field has been recognized as an important element of the solar flare process. This Letter reports such a rapid change of magnetic fields during the 2011 February 13 M6.6 flare in NOAA AR 11158 that we found from the vector magnetograms of the Helioseismic and Magnetic Imager with 12-min cadence. High-resolution magnetograms of Hinode that are available at ~-5.5, -1.5, 1.5, and 4 hrs relative to the flare maximum are used to reconstruct three-dimensional coronal magnetic field under the nonlinear force-free field (NLFFF) assumption. UV and hard X-ray images are also used to illuminate the magnetic field evolution and energy release. The rapid change is mainly detected by HMI in a compact region lying in the center of the magnetic sigmoid, where the mean horizontal field strength exhibited a significant increase by 28%. The region lies between the initial strong UV and hard X-ray sources in the chromosphere, which are cospatial with the central feet of the sigmoid according to the NLFFF model. The NLFFF model further shows that strong coronal currents are concentrated immediately above the region, and that more intriguingly, the coronal current system underwent an apparent downward collapse after the sigmoid eruption. These results are discussed in favor of both the tether-cutting reconnection producing the flare and the ensuing implosion of the coronal field resulting from the energy release.

Solution of the momentum-space Schrödinger equation for bound states of the N-dimensional Coulomb problem (revisited)

description: The Schrödinger-Coulomb Sturmian problem in $\mathbb{R}^{N}$, $N\geqslant2$, is considered in the momentum representation. An integral formula for the Gegenbauer polynomials, found recently by Cohl [arXiv:1105.2735], is used to separate out angular variables and reduce an integral Sturmian eigenvalue equation in $\mathbb{R}^{N}$ to a Fredholm one on $\mathbb{R}_{+}$. A kernel of the latter equation contains the Legendre function of the second kind. A symmetric Poisson-type series expansion of that function into products of the Gegenbauer polynomials, established by Ossicini [Boll. Un. Mat. Ital. 7 (1952) 315], is then used to determine the Schrödinger-Coulomb Sturmian eigenvalues and associated momentum-space eigenfunctions. Finally, a relationship existing between solutions to the Sturmian problem and solutions to a (physically more interesting) energy eigenvalue problem is exploited to find the Schrödinger-Coulomb bound-state energy levels in $\mathbb{R}^{N}$, together with explicit representations of the associated normalized momentum-space Schrödinger-Coulomb Hamiltonian eigenfunctions.

Asymptotics of generalized Galois numbers via affine Kac-Moody algebras

description: Generalized Galois numbers count the number of flags in vector spaces over finite fields. Asymptotically, as the dimension of the vector space becomes large, we give their exponential growth and determine their initial values. The initial values are expressed analytically in terms of theta functions and Euler's generating function for the partition numbers. Our asymptotic enumeration method is based on a Demazure module limit construction for integrable highest weight representations of affine Kac-Moody algebras. For the classical Galois numbers, that count the number of subspaces in vector spaces over finite fields, the theta functions are Jacobi theta functions. We apply our findings to the asymptotic number of q-ary codes, and conclude with some final remarks about possible future research concerning asymptotic enumerations via limit constructions for affine Kac-Moody algebras.

description: Charge carrier mobility in disordered organic materials is being actively studied, motivated by several applications such as organic light emitting diodes and organic field-effect transistors. It is known that the mobility in disordered organic materials depends on the chemical potential which in turn depends on the carrier concentration. However, the functional dependence of chemical potential on the carrier concentration is not known. In this study, we focus on the chemical potential in organic materials with Gaussian disorder. We identify three cases of non-degenerate, degenerate and saturated regimes. In each regime we calculate analytically the chemical potential as a function of the carrier concentration and the energetic disorder from the first principles.
