description: With an implicit Particle-in-cell/Monte Carlo model, capacitively coupled plasmas are studied in two-dimensional and axisymmetric geometry. Self-bias dc voltage effects are self-consistently considered. Due to finite length effects, the self-bias dc voltages show sophisticating relations with the electrode areas. Two-dimensional kinetic effects are also illuminated. Compare to the fluid mode, PIC/MC model is numerical-diffusion-free and thus finer properties of the plasmas are simulated.

How to suppress the shot noise in galaxy surveys

description: Galaxy surveys are one of the most powerful means to extract the cosmological information and for a given volume the attainable precision is determined by the galaxy shot noise sigma_n^2 relative to the power spectrum P. It is generally assumed that shot noise is white and given by the inverse of the number density n. In this paper we argue one may be able to considerably improve upon this: in the halo picture of cosmological structure all of the dark matter is in halos of varying mass and galaxies are formed inside these halos, but for the dark matter mass and momentum conservation guarantee that nonlinear effects cannot develop a white noise in the dark matter power spectrum on large scales. This suggests that with a suitable weighting a similar effect may be achieved for galaxies, suppressing their shot noise. We explore this idea with N-body simulations by weighting central halo galaxies by halo mass and find that the resulting shot noise can be reduced dramatically relative to expectations, with a 10-30 suppression at the highest number density of n=4*10^-3 (Mpc/h)^3 resolved in our simulations. For specific applications other weighting schemes may achieve even better results and for n=3*10^-4(Mpc/h)^3 we can reduce sigma_n^2/P by up to a factor of 10 relative to uniform weighting. These results open up new opportunities to extract cosmological information in galaxy surveys, such as the recently proposed multi-tracer approach to cancel sampling variance, and may have important consequences for the planning of future redshift surveys. Taking full advantage of these findings may require better understanding of galaxy formation process to develop accurate tracers of the halo mass.

description: Spiking neural networks (SNNs) present a promising computing paradigm for neuromorphic processing of event-based sensor data. The resonate-and-fire (RF) neuron, in particular, appeals through its biological plausibility, complex dynamics, yet computational simplicity. Despite theoretically predicted benefits, challenges in parameter initialization and efficient learning inhibited the implementation of RF networks, constraining their use to a single layer. In this paper, we address these shortcomings by deriving the RF neuron as a structured state space model (SSM) from the HiPPO framework. We introduce S5-RF, a new SSM layer comprised of RF neurons based on the S5 model, that features a generic initialization scheme and fast training within a deep architecture. S5-RF scales for the first time a RF network to a deep SNN with up to four layers and achieves with 78.8% a new state-of-the-art result for recurrent SNNs on the Spiking Speech Commands dataset in under three hours of training time. Moreover, compared to the reference SNNs that solve our benchmarking tasks, it achieves similar performance with much fewer spiking operations.

Particle Flow Calorimetry and the PandoraPFA Algorithm

description: The Particle Flow (PFlow) approach to calorimetry promises to deliver unprecedented jet energy resolution for experiments at future high energy colliders such as the proposed International Linear Collider (ILC). This paper describes the PandoraPFA particle flow algorithm which is then used to perform the first systematic study of the potential of high granularity PFlow calorimetry. For simulated events in the ILD detector concept, a jet energy resolution of sigma_E/E < 3.8 % is achieved for 40-400 GeV jets. This result, which demonstrates that high granularity PFlow calorimetry can meet the challenging ILC jet energy resolution goals, does not depend strongly on the details of the Monte Carlo modelling of hadronic showers. The PandoraPFA algorithm is also used to investigate the general features of a collider detector optimised for high granularity PFlow calorimetry. Finally, a first study of the potential of high granularity PFlow calorimetry at a multi-TeV lepton collider, such as CLIC, is presented.

description: Many mechanisms, functions and structures of life have been unraveled. However, the fundamental driving force that propelled chemical evolution and led to life has remained obscure. The 2nd law of thermodynamics, written as an equation of motion, reveals that elemental abiotic matter evolves from the equilibrium via chemical reactions that couple to external energy toward complex biotic non-equilibrium systems. Each time a new mechanism of energy transduction emerges, e.g., by random variation in syntheses, evolution prompts by punctuation and settles to a stasis when the accessed free energy has been consumed. The evolutionary course toward an increasingly larger energy transduction system accumulates a diversity of energy transduction mechanisms, i.e., species. The rate of entropy increase is identified as the fitness criterion among the diverse mechanisms which places the theory of evolution by natural selection on the fundamental thermodynamic principle with no demarcation line between inanimate and animate.

Terahertz Radar for Stand Off Through Clothes Imaging Slides
Creators: Goutam Chattopadhyay

MTT Webinar Slides
Demand for new surveillance capabilities for usage in airport screenings and battlefield security check-points has led to the development of terahertz imagers and sensors. There are several advantages of imaging at terahertz frequencies compared to microwave or infrared: the wavelengths in this regime are short enough to provide high resolution with modest apertures, yet long enough to penetrate clothing. Moreover, unlike in infrared, the terahertz frequencies are not affected by dust, fog, and rain. Several groups around the world are working on the development of terahertz imagers for various applications. One option is to use passive imaging techniques, which were very successful at millimeter-wave frequencies, by scaling in frequencies to terahertz range. However, the background sky is much warmer at terahertz frequencies due to high atmospheric absorption. Since passive imagers detect small differences in temperatures from the radiating object against the sky background, at these frequencies passive imagers do not provide enough scene contrast for short integration times. On the other hand, in an active imager, the object is illuminated with a terahertz source and the resulting reflected/scattered radiation is detected to make an image. However, the glint from the background clutter in an active terahertz imager makes it hard to provide high fidelity images without a fortunate alignment between the imaging system and the target. We have developed an ultra wideband radar based terahertz imaging system that addresses many of these issues and produces high resolution through-clothes images at stand-off distances. The system uses a 675 GHz solid-state transmit/receive system in a frequency modulated continuous wave (FMCW) radar mode working at room temperature. The imager has sub-centimeter range resolution by utilizing a 30 GHz bandwidth. It has comparable cross-range resolution at a 25m stand-off distance with a 1m aperture mirror. A fast rotating small secondary mirror rapidly steers the projected beam over a 50 x 50 cm target at range to produce images at frame rates exceeding 1 Hz.  This presentation  explains in detail the design and implementation of the terahertz imaging radar system. We will show how by using a time delay multiplexing of two beams, we achieved a two-pixel imaging system using a single transmit/receive pair. Moreover, we will also show how we improved the signal to noise of the radar system by a factor of 4 by using a novel polarizing wire grid and grating reflector.  The research described herein was carried out at the Jet Propulsion Laboratory, California Institute of Technology, Pasadena, California, USA, under contract with National Aeronautics and Space Administration.

Given three minutes, you have to present your complex, highly technical work to an audience that is educated, but that has specialized neither in your personal niche nor even in your broad field of endeavor. Is it even possible? Can you capture the non-specialist imagination and inspire them to ask for more? Sheer enthusiasm is not enough to hold people’s attention for any length of time. To engage them, it takes practice and empathy. First challenge you have to kill the jargon. In this webinar we address the art of brief, effective live communication of complex technical material in language suited to a non-specialist audience. We draw on actual 3MT® experience, including organizing, mentoring and hands-on competing. Much of what we discuss is applicable to regular technical presentations: the importance of first impressions, subtext, authenticity, articulation, stage presence, slide composition, metaphor, story-telling, authenticity, articulation, and much more.

description: We study induced modules of nonzero central charge with arbitrary multiplicities over affine Lie algebras. For a given pseudo parabolic subalgebra ${\mathcal P}$ of an affine Lie algebra ${\mathfrak G}$, our main result establishes the equivalence between a certain category of ${\mathcal P}$-induced ${\mathfrak G}$-modules and the category of weight ${\mathcal P}$-modules with injective action of the central element of ${\mathfrak G}$. In particular, the induction functor preserves irreducible modules. If ${\mathcal P}$ is a parabolic subalgebra with a finite-dimensional Levi factor then it defines a unique pseudo parabolic subalgebra ${\mathcal P}^{ps}$, ${\mathcal P}\subset {\mathcal P}^{ps}$. The structure of ${\mathcal P}$-induced modules in this case is fully determined by the structure of ${\mathcal P}^{ps}$-induced modules. These results generalize similar reductions in particular cases previously considered by V. Futorny, S. König, V. Mazorchuk [Forum Math. 13 (2001), 641-661], B. Cox [Pacific J. Math. 165 (1994), 269-294] and I. Dimitrov, V. Futorny, I. Penkov [Comm. Math. Phys. 250 (2004), 47-63].

description: A leading interpretation of the electron/positron excesses seen by PAMELA and ATIC is dark matter annihilation in the galactic halo. Depending on the annihilation channel, the electron/positron signal could be accompanied by a galactic gamma ray or neutrino flux, and the non-detection of such fluxes constrains the couplings and halo properties of dark matter. In this paper, we study the interplay of electron data with gamma ray and neutrino constraints in the context of cascade annihilation models, where dark matter annihilates into light degrees of freedom which in turn decay into leptons in one or more steps. Electron and muon cascades give a reasonable fit to the PAMELA and ATIC data. Compared to direct annihilation, cascade annihilations can soften gamma ray constraints from final state radiation by an order of magnitude. However, if dark matter annihilates primarily into muons, the neutrino constraints are robust regardless of the number of cascade decay steps. We also examine the electron data and gamma ray/neutrino constraints on the recently proposed "axion portal" scenario.

To fit the supernova data, a large local void on the scales of 1 Gpc is found, contrary to the small scales of 200 Mpc in the previous finding. A more realistic inhomogeneous cosmological model may be required to fit the supernova data. Alternatively, a clumpy universe with clumpiness parameter < 1 can fit the supernova data with reduced local void scales.

Fourteen ways of looking at a blackbird : point of view in The Sound and the Fury
Creators: name: Layman, Lewis Magnus
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is an intensive analysis of The Sound and the Fury, focussing on Faulkner's treatment of point of view. The novel is examined as an exploration of the act of perception, reflecting the author's Bergsonian view of consciousness. Faulkner's statement that every reflector sees one aspect of the truth and that the writing of the novel is an attempt to achieve a comprehensive overview is used as a focal point for the thesis. In the introductory chapter I state my basic approach: to discuss the validity and distortion of each point of view as conveyed by the rendering of authorial involvement and distance from the presented perspectives. Before applying these criteria to the reflectors of the novel, I briefly discuss The Sound and the Fury in relation to As I Lay Dying, Light in August, Absalom, Absalom! and Go Down, Moses. The four subsequent chapters are close analyses of each section of the book. I emphasize Benjy's function as a literal embodiment of the Compson dilemma. In Chapter 3 I stress the relationship of Quentin's monologue to Benjy's as a reflection of the growth of consciousness. I also explore the significance of incest and the quixotic aspects of Quentin's character. The focus of Chapter 4 is upon Jason as a reflector who fully expresses the negative impulses to renounce responsibilities and withdraw from human involvement. I suggest that Part Three is simultaneously a realization of destructive possibilities and a kind of comic relief. The likelihood that Joyce's use of perspective in the Cyclops episode of Ulysses was a precedent for this horror-comedy is explored. In Chapter Five I examine the narrative point of view and the way the language of Section Four reflects the process of perception. I study the interrelationship of the various parts of this section to each other and to the monologues of the Compson brothers. I assert that there is a sense of affirmation, stemming from the author's and audience's ability to comprehend the significance of experience, that is not embodied in any characters in the novel. The final chapter contains some general conclusions about the book and a discussion of the "Appendix" written in 1945. By intensively analyzing aspects of the novel such as the use of multi-perspectives, the function of a character who begins and ends the book, and the anti-climactic ending, I have striven to achieve two goals. First, I have attempted to gain a full understanding of The Sound and the Fury. Second, in exploring distinctive and essential features of Faulkner's novels I have sought to gain insight into his works as a whole.

Dynamic measurement of hydrologic characteristics of a layered soi l during drainage, evaporation and subsequent wetting
Creators: name: Chow, Thien Lien
Publisher: name: University of British Columbia
Year: 2011

description: Instrumentation and methodology were developed and used for dynamic measurement of hydrologic characteristics of an undisturbed layered soil column over the soil water matric potential range between -0.1 and -90 bars. This instrumentation included the gamma radiation attenuation technique to measure water content and the tensiometer-pressure transducer and the three-terminal double loop thermocouple psychrometer techniques to measure water potential. The thermal stability of this psychrometer is approximately 40 times better than that of the two-terminal psychrometer (Spanner type) for ambient temperature fluctuations with a time rate of change greater than 0.2°C/min. Water potential measurements carried out with this psychrometer on silty clay and silt loam soil samples were within ± 0.4 bar of the porous plate extractor equilibrium values. Water content and the corresponding water potential of an undisturbed layered soil were measured simultaneously with this instrumentation as a continuous function of time and depth for the soil water matric potential between -0.1 and -90 bars. These measurements were carried out during water flow induced by drainage and evaporation, followed by rewetting. Water retention and flow characteristics were then calculated from these measurements. The same properties were also determined for the top layer separately. None of these properties showed system dependence. Both water retention, w(ψ[sub M]), and unsaturated hydraulic conductivity-matric potential function, K(ψ[sub M]), showed hysteresis effects at soil water matric potential (ψ[sub M]) between -0.1 and -3.0 bars, w(ψ[sub M]) showed no hysteresis at ψ[sub M]> -3.0 bars, whereas K(ψ[sub M]) showed inconclusive hysteresis in this range. The unsaturated hydraulic conductivity-water content function, K(w), and diffusivity-water content function, D(w), displayed inconclusive hysteresis. Propagated errors in both unsaturated hydraulic conductivity and diffusivity were estimated to be ± 7.8 to ± 20.0% and ± 8.1 to ± 38.2% respectively.

description: We present the color-magnitude and color-stellar mass diagrams for galaxies with z_phot < ~2, based on a K < 22 (AB) catalog of the Extended Chandra Deep Field South (ECDFS) from the MUltiwavelength Survey by Yale-Chile (MUSYC). Our main sample of 7840 galaxies contains 1297 M_* > 10^11 M_Sol galaxies in the range 0.2 < z_phot < 1.8. We show empirically that this catalog is approximately complete for M_* > 10^11 M_Sol galaxies for z_phot < 1.8. For this mass-limited sample, we show that the locus of the red sequence color-stellar mass relation evolves as Del(u-r) ~ (-0.44+/-0.02) z_phot for z_phot < ~1.2. For z_phot > ~1.3, however, we are no longer able to reliably distinguish red and blue subpopulations from the observed color distribution; we show that this would require much deeper near infrared data. At 1.5 < z_phot <1.8, the comoving number density of M_* > 10^11 M_Sol galaxies is ~50% of the local value, with a red fraction of ~33%. Making a parametric fit to the observed evolution, we find n_tot(z) ~ (1+z_phot)^(-0.52+/-0.12(+/-0.20)). We find stronger evolution in the red fraction: f_red(z) ~ (1+z_phot)^(-1.17+/-0.18(+/-0.21)). Through a series of sensitivity analyses, we show that the most important sources of systematic error are: 1. systematic differences in the analysis of the z~0 and z>>0 samples; 2. systematic effects associated with details of the photometric redshift calculation; and 3. uncertainties in the photometric calibration. With this in mind, we show that our results based on photometric redshifts are consistent with a completely independent analysis which does not require redshift information for individual galaxies. Our results suggest that, at most, 1/5 of local red sequence galaxies with M_* >10^11 M_Sol were already in place at z ~ 2.

description: We present a theory of neutrino interactions with nuclei aimed at the description of the partial cross-sections, namely quasi-elastic and multi-nucleon emission, coherent and incoherent single pion production. For this purpose, we use the theory of nuclear responses treated in the random phase approximation, which allows a unified description of these channels. It is particularly suited for the coherent pion production where collective effects are important whereas they are moderate in the other channels. We also study the evolution of the neutrino cross-sections with the mass number from carbon to calcium. We compare our approach to the available neutrino experimental data on carbon. We put a particular emphasis on the multi-nucleon channel, which at present is not easily distinguishable from the quasi-elastic events. This component turns out to be quite relevant for the interpretation of experiments (K2K, MiniBooNE, SciBooNE). It can account in particular for the unexpected behavior of the quasi-elastic cross-section.

Millimeter Wave Power Amplifiers: State of the Art and Future Technology Trends Slides

MTT Webinar Slides
With 5G communication just around the corner, there is a rapidly increasing need for high-performance mm-Wave power amplifiers (PA). However, these next-generation mm-Wave PAs are often expected to deliver nearly “perfect” performance. They should offer large output power to ensure sufficient link budget, broad bandwidth to support multi-standard communication or frequency reconfigurability/agility, high peak and back-off efficiency for energy saving, and also inherent linearity for Gbit/s complex modulations with minimum or even no digital pre-distortions (DPD). It is noteworthy that in conventional design notions a given PA design should typically take trade-offs among these performance aspects. Interestingly, this somehow unreasonable quest for “perfect” mm-Wave PAs has recently stimulated a new wave of mm-Wave PA innovations at both circuit levels and architecture levels in recent years. In this webinar, we  first review the state of the art of mm-Wave PA technologies and identify the technology trends based on the "Power Amplifiers Performance Survey 2000-Present" by research group at Georgia Tech. Next, we present several recent mm-Wave PA designs that feature various innovations at both circuit-level and architecture-level. We will also showcase several mm-Wave PA/antenna co-design examples that exploit this new design paradigm to further enhance mm-Wave PA output power and efficiency.

description: Magnetic tunnel junctions for spin-transfer torque switching were prepared to investigate the dielectric breakdown. The breakdown occurs typically at voltages not much higher than the switching voltages, a bottleneck for the implementation of spin-transfer torque Magnetic Random Access Memory. Intact and broken tunnel junctions are characterized by transport measurements and then prepared for transmission electron microscopy and energy dispersive x-ray spectrometry by focussed ion beam. The comparison to our previous model of the electric breakdown for thicker MgO tunnel barriers reveals significant differences arising from the high current densities.

description: In an earlier paper Cooper, Shepard, and Sodano introduced a generalized KdV equation that can exhibit the kinds of compacton solitary waves that were first seen in equations studied by Rosenau and Hyman. This paper considers the PT-symmetric extensions of the equations examined by Cooper, Shepard, and Sodano. From the scaling properties of the PT-symmetric equations a general theorem relating the energy, momentum, and velocity of any solitary-wave solution of the generalized KdV equation is derived, and it is shown that the velocity of the solitons is determined by their amplitude, width, and momentum.

MTT Webinar Slides
Widespread applications and commercial success of GHz and THz electronic and photonic devices and systems including RF, microwaves and millimeter-waves are closely related to their manufacturing cost and antenna-circuit integration. Our proposed integration technology of planar and non-planar structures as well as related new progress indicate that the emerging substrate integrated circuits (SICs) are able to provide unprecedented advantages for developing low-cost GHz/THz components, antennas, circuits and systems as well as wireless photonic applications. This talk reviews the state-of-the-art and underlying features of the proposed integration platforms for designing the next generation RF/millimeter-wave/THz ICs and systems. Challenging issues and future directions are discussed for R&D opportunities. Potential problems and possible solutions are also presented. It is believed that the technological platform of SICs will offer a cost-effective and performance-promising solution for mass commercial applications. With the development of innovative fabrication processes and material synthesis techniques, unique hybrid and monolithic high-density integration of planar and non-planar structures (or system-on-substrate approach) become realizable. It can also be demonstrated that this scheme of SICs may be able to effectively bridge the gap between electronics and photonics. In this presentation, global research activities and future RF/millimeter-wave developments will be discussed.

description: Being able to quickly select among gamma-ray bursts (GRBs) seen by the Swift satellite those which are high-z candidates would give ground-based observers a better chance to determine a redshift for such distant GRBs. Information about these high-z GRBs is important in helping to resolve questions about the early universe such as the formation rate of high-z GRBs, the re-ionization period of the universe, the metallicity of the early universe, and the Hubble expansion. Initially using a sample of 51 GRBs with previously measured redshifts, we have developed high-z screening criteria employing the GRB spectral as well as temporal characteristics of the prompt emission from the Burst Alert Telescope (BAT) on Swift. Now that the sample has increased to 81 GRBs, we have revisited the screening criteria and our methodology. Our updated high-z screening criteria are presented in this paper.

The Dirac Equation, Mass and Arithmetic by Permutations of Automaton States

description: The cornerstones of the Cellular Automaton Interpretation of Quantum Mechanics are its underlying ontological states that evolve by permutations. They do not create would-be quantum mechanical superposition states. We review this with a classical automaton consisting of an Ising spin chain which is then related to the Weyl equation in the continuum limit. Based on this and generalizing, we construct a new ``Necklace of Necklaces'' automaton with a torus-like topology that lends itself to represent the Dirac equation in 1 + 1 dimensions. Special attention has to be paid to its mass term, which necessitates this enlarged structure and a particular scattering operator contributing to the step-wise updates of the automaton. As discussed earlier, such deterministic models of discrete spins or bits unavoidably become quantum mechanical, when only slightly deformed.

La tradizione dell amalattia d'amore dal mondo classico allo Scriptum super cantilena Guidonis de Cavalcantibus di Dino del Garbo
Creators: name: Ciavolella, Massimo
Publisher: name: University of British Columbia
Year: 2011

description: This study traces the evolution of the medical concept of aegritudo amoris from the Greeks to the end of the Middle Ages, paying attention to the correlation between medical doctrines and literary conventions. In Chapter One it is argued that the concept of love-sickness has its roots in the doctrine of melancholy and of folly developed by the Hippocratic writers. The evolution of the concept is not, however, restricted within the narrow limits of the medical tradition, but it is characterized by a gradual penetration of elements taken from Greek philosophy, represented by Plato and Aristotle, and from the literary tradition, especially Euripides. The influence of this concept is traced through the Roman world (the story of Antiochus and Stratonices, Lucretius, Ovid) and through the writings of the early Fathers of the Church. Chapter Two follows the development of the medical concept of love-sickness from the Byzantine physicians Oribasius and Paulus Aegineta to those medical writers, Arabic and Latin, who dedicated sections of their works to the study of love. The second part of the Chapter provides a transcription of these medical treatments of love. The final Chapter assesses the contribution of this tradition to the literature of the late Middle Ages, through an examination of three prose-treatises on love, the first Arabic: The Dove's Meek Ring by Ibn Hazm, the second French: the De Amore by Andreas Capellanus, the third Italian: the Scriptum super cantilena Guidonis de Cavalcantibus by Dino del Garbo. Finally, the canzone "Donna me prega" by Cavalcanti is examined both from a thematic point of view and in relation to the conception of love developed by Cavalcanti’s "primo amico", Dante Alighieri.

description: We have used Low Energy Electron Microscopy (LEEM) and Photo Emission Electron Microscopy (PEEM) to study and improve the quality of graphene films grown on Ir(111) using chemical vapor deposition (CVD). CVD at elevated temperature already yields graphene sheets that are uniform and of monatomic thickness. Besides domains that are aligned with respect to the substrate, other rotational variants grow. Cyclic growth exploiting the faster growth and etch rates of the rotational variants, yields films that are 99 % composed of aligned domains. Precovering the substrate with a high density of graphene nuclei prior to CVD yields pure films of aligned domains extending over millimeters. Such films can be used to prepare cluster-graphene hybrid materials for catalysis or nanomagnetism and can potentially be combined with lift-off techniques to yield high-quality, graphene based electronic devices.
