description: If superconductivity is induced in the metallic surface states of topological insulators via proximity, Majorana modes will be trapped on the vortex cores. The same effects hold for doped topological insulators which become bulk s-wave superconductors as long as the doping does not exceed a critical values $ μ^{\pm}_c.$ It is this critical chemical potential at which the material forgets it arose from a band-inverted topological insulator; it loses its topological \emph{imprint.} For the most common classes of topological insulators, which can be modeled with a minimal 4-band Dirac model the values of $μ^{\pm}_c$ can be easily calculated, but for materials with more complicated electronic structures such as HgTe or ScPtBi the result is unknown. We show that due to the hybridization with an additional Kramers' pair of topologically trivial bands the topological imprint of HgTe-like electronic structures (which includes the ternary Heusler compounds) can be widely extended for p-doping. As a practical consequence we consider the effects of such hybridization on the range of doping over which Majorana modes will be bound to vortices in superconducting topological insulators and show that the range is strongly extended for p-doping, and reduced for n-doping. This leaves open the possibility that other topological phenomena may be stabilized over a wider range of doping.

description: A common result to all EMRI investigations on rates is that the possibility that a compact object merges with the MBH after only one intense burst of GWs is much more likely than a slow adiabatic inspiral, an EMRI. The later is referred to as a "plunge" because the compact object dives into the MBH. The event rates for plunges are orders of magnitude larger than slow inspirals. On the other hand, nature MBH's are most likely Kerr and the magnitude of the spin has been sized up to be high. We calculate the number of periapsis passages that a compact object set on to an extremely radial orbit goes through before being actually swallowed by the Kerr MBH and we then translate it into an event rate for a LISA-like observatory, such as the proposed ESA mission eLISA/NGO. We prove that a "plunging" compact object is conceptually indistinguishable from an adiabatic, slow inspiral; plunges spend on average up to hundred of thousands of cycles in the bandwidth of the detector for a two years mission. This has an important impact on the event rate, enhancing in some cases significantly, depending on the spin of the MBH and the inclination. Moreover, it has been recently proved that the production of low-eccentricity EMRIs is severely blocked by the presence of a blockade in the rate at which orbital angular momenta change takes place. This is the result of relativistic precession on to the stellar potential torques and hence affects EMRIs originating via resonant relaxation at distances of about $\sim 10^{-2}$ pc from the MBH. Since high-eccentricity EMRIs are a result of two-body relaxation, they are not affected by this phenomenon. Therefore we predict that eLISA EMRI event rates will be dominated by high-eccentricity binaries, as we present here.

Learning Smooth Pattern Transformation Manifolds

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: Manifold models provide low-dimensional representations that are useful for processing and analyzing data in a transformation-invariant way. In this paper, we study the problem of learning smooth pattern transformation manifolds from image sets that represent observations of geometrically transformed signals. In order to construct a manifold, we build a representative pattern whose transformations accurately fit various input images. We examine two objectives of the manifold building problem, namely, approximation and classification. For the approximation problem, we propose a greedy method that constructs a representative pattern by selecting analytic atoms from a continuous dictionary manifold. We present a DC (Difference-of-Convex) optimization scheme that is applicable to a wide range of transformation and dictionary models, and demonstrate its application to transformation manifolds generated by rotation, translation and anisotropic scaling of a reference pattern. Then, we generalize this approach to a setting with multiple transformation manifolds, where each manifold represents a different class of signals. We present an iterative multiple manifold building algorithm such that the classification accuracy is promoted in the learning of the representative patterns. Experimental results suggest that the proposed methods yield high accuracy in the approximation and classification of data compared to some reference methods, while the invariance to geometric transformations is achieved due to the transformation manifold model.

description: We compute the accuracy at which a LISA-like space-based gravitational wave detector will be able to observe deviations from General Relativity in the low frequency approximation. To do so, we introduce six correction parameters that account for modified gravity in the second post-Newtonian gravitational wave phase for inspiralling supermassive black hole binaries with spin precession on quasi-circular orbits. Our implementation can be regarded as a subset of the ppE formalism developed by Yunes and Pretorius, being able to investigate also next-to-leading order effects. In order to find error distributions for the alternative theory parameters, we use the Fisher information formalism and carry out Monte Carlo simulations for 17 different binary black hole mass configurations in the range 10^5 Msun < M < 10^8 Msun with 10^3 randomly distributed points in the parameter space each, comparing the full (FWF) and restricted (RWF) version of the gravitational waveform. We find that the binaries can roughly be separated into two groups: one with low (< ~10^7 Msun) and one with high total masses (> ~10^7 Msun). The RWF errors on the alternative theory parameters are two orders of magnitude higher than the FWF errors for high-mass binaries while almost comparable for low-mass binaries. Due to dilution of the available information, the accuracy of the binary parameters is reduced by factors of a few, except for the luminosity distance which is affected more seriously in the high-mass regime. As an application and to compare our research with previous work, we compute an optimal lower bound on the graviton Compton wavelength which is increased by a factor of ~1.6 when using the FWF.

description: This paper describes the design of a resistive monolithic Q-band HEMT mixer for optimum conversion loss and IMD performance. Transistor two-sided harmonic measurements across Vds and Vgs revealed the presence of IMD sweet spots that were used to optimize the conversion loss and IMD behavior of the mixer.Minimum conversion loss of 10 dB was measured in the 40.8-49 GHz RF frequency band,showing a reasonable agreement with simulation results.Mixer single-tone IMD was measured and simulated.The minimum output level at 3FIF was less than –102 dBm for an RF input level of –10 dBm and for a bias point near the predicted sweet spot.

description: We add massive fundamental matter to the ABJM model by adding D6-branes wrapped asymptotically over RP3. We find two types of solutions at finite temperature, one that enters the black hole and one that ends before the black hole. We analyze the behavior of the free energy as a function of temperature, and find that the system exhibits a phase transition between the two types of solutions, similar to what happens in the D3-D7 system. We also analyze the meson spectrum in the model and find several massive scalar modes, again, quite like the D3-D7 system. We end with a calculation of the conductivities in the two phases.

Characterization of interactions of TonB and Colicin M with FhuA reconstituted into Nanodiscs
Creators: name: Mills, Allan
Publisher: name: University of British Columbia
Year: 2013

description: TonB-dependent transporters are β-barrel outer membrane proteins that depend on interactions with the inner membrane protein TonB to drive import of scarce nutrients. Upon becoming ligand-loaded, TonB-dependent transporters bind TonB through a β-strand exchange. FhuA is the TonB-dependent transporter that transports hydroxamate iron siderophores, such as ferrichrome and ferricrocin, into the periplasm and also acts as the receptor and transporter of the antimicrobial protein colicin M. The interactions of FhuA with TonB have previously been investigated in detergents, which can affect the conformations of TonB-dependent transporters and alter their interaction with TonB. To exclude the potential negative effects of detergent, FhuA was reconstituted into Nanodiscs that reconstitute a membrane-like environment suitable for biochemical analysis. Binding of TonB to FhuA was found to be strongly dependent on the ligand-loaded state of FhuA. The binding affinity was relatively high (~200 nM) and enthalpy driven, suggesting a disorder-to-order interaction occurring during the β-strand exchange. Colicin M also bound Nanodisc reconstituted FhuA with a high affinity (~3.5 nM) through an entropy driven interaction that may reflect a hydrophobic interaction. The ligand ferricrocin inhibited the binding of colicin M to FhuA. While TonB is required for transport of colicin M into cells, colicin M was not observed to cause the recruitment of TonB to FhuA. Finally, the conformation of FhuA was investigated in the presence of ferricrocin and colicin M by partial proteolysis.

"Open" chromatin : histone acetylation, linker histones & histone variants
Creators: name: Choi, Jennifer Kristel
Publisher: name: University of British Columbia
Year: 2014

description: DNA in the eukaryotic cell is packaged into a structure called chromatin. Chromatin is a dynamic structure that regulates access to DNA in response to environmental stimuli. Two widely conserved mechanisms that influence chromatin structure are the addition of post-translational modifications (PTMs) to histones and other chromatin-associated proteins, and the replacement of canonical histones with histone variants. Histone acetylation is catalyzed by histone acetyltransferases (HATs). HATs are comprised of a catalytic subunit, and associated proteins. Genetic analysis of the yeast HATs has shown that the combined deletion of the two HAT genes, GCN5 and SAS3, results in an inviable strain of yeast. In this thesis, I show that the inviability of the gcn5Δsas3Δ mutant is due to a combined failure to acetylate both histone H3 and the chromatin-remodeler protein Rsc4. Further, I show that acetylation of Rsc4 is catalyzed by Gcn5 in a HAT complex-independent manner. The linker histone, H1, is associated with higher-order chromatin structure; it has been shown that removal of H1 is required to allow access to DNA. In this work, I show that deletion of the linker histone rescues the growth of a conditional gcn5Δ sas3Δ mutant expressing a temperature-sensitive version of Sas3. Further, I present the incorporation of the histone variant Htz1 as an additional mechanism for mobilizing the linker histone away from the +1 nucleosome. I, also, provide data that corroborates evidence suggesting that the yeast linker histone binds a single nucleosome. Another histone variant found in many eukaryotes is histone H3.3, which is primarily incorporated into transcriptionally active regions in chromatin. In this dissertation, we created a series of human-yeast histone hybrids and tested their ability to rescue yeast lacking both endogenous copies of histone H3. Our data shows that the two human histone H3 variants, H3.1 and H3.3, are functionally interchangeable for growth in most nutrient conditions, confirming that the four amino acids that are different between H3.1 and H3.3 are not necessary to create transcriptionally permissive chromatin. Finally, we present evidence that three yeast H3 C-terminal domain amino acids play an important role in regulating the interactions of yeast H3.

description: Recent commercial wireless applications such as Point to Point radio links, LMDS (Local Multipoint  istribution Service), LMCS (Local multi-point Communications Service) and Commercial K-Band Satellite based services have spurred significant activity in development of mmWave power amplifiers. These applications lie in the frequency range of 18 to 42GHz with possible future extensions to 60GHz. These systems employ digital modulation schemes for which highly linear mmWave power amplifiers are essential. This paper presents an overview of some chipsets consisting of High Power amplifiers covering the frequency range of 18 to 32GHz. Preferred solutions to a low cost subsystem vary from one subsystem manufacturer to another as it involves assembly and test capabilities in addition to component costs. The overall direction appears to be toward multi-chip moduleassemblies. Here, both chip and packaged level component options are considered.

description: A fully integrated dual-frequency VCO providing not only a high frequency LO signal to transceiver mixers but also a half-LO-frequency signal to a PLL is described. The circuit has 1.2 GHz tuning range at 7 GHz, 25-dB suppression of fundamental-frequency (3.5-GHz) signal at 7-GHz port, and more than 20dB suppression of 7-GHz-signal at 3.5-GHz port. The VCO chip was packaged and resembled on board for phase-noise measurement. A phase noise of – 80 dBc/Hz at 100kHz offset frequency was obtained. This work avoids the use of frequency dividers, hence the chip sizes, power consumption and cost are reduced.

description: In disturbance-prone ecosystems, fitness consequences of plant reproductive strategies are often determined by the relative timing of seed production and disturbance events, but the role of disturbances as proximate drivers of seed production has been overlooked. We use long-term data on seed production in Quercus chapmanii, Q. geminata and Q. inopina, rhizomatous oaks found in Southcentral Florida's oak scrub, to investigate the role of fire history and its interaction with weather in shaping acorn production and its synchrony. Acorn production increased with the time since last fire, combined with additive or interactive effects of spring precipitation (+) or drought (–). Furthermore, multiple matrix regression models revealed that ramet pairs with shared fire history were more synchronous in seed production than ones that burned in different years. Long-term trends suggest that increasingly drier spring weather, in interaction with fire frequency, may drive a decline of seed production. Such declines could affect the community of acorn-reliant vertebrates in the Florida scrub, including endangered Florida scrub-jays (Aphelocoma coerulescens). These results illustrate that fire can function as a proximate driver of seed production in mast-seeding species, highlighting the increasingly recognized importance of interactions among reproductive strategies and disturbance regimes in structuring plant populations and communities.This article is part of the theme issue ‘The ecology and evolution of synchronized seed production in plants’.

description: We aim at an explicit characterization of the renormalized Hamiltonian after decimation transformation of a one-dimensional Ising-type Hamiltonian with a nearest-neighbor interaction and a magnetic field term. To facilitate a deeper understanding of the decimation effect, we translate the renormalization flow on the Ising Hamiltonian into a flow on the associated Markov chains through the Markov-Gibbs equivalence. Two different methods are used to verify the well-known conjecture that the eigenvalues of the linearization of this renormalization transformation about the fixed point bear important information about all six of the critical exponents. This illustrates the universality property of the renormalization group map in this case.

description: This paper is intended to give an insight in the development of PHEMT multifunction MMICs (MFC) in the millimetre wave frequency range. It applies to the fast growing Multipoint video Distribution System (MVDS) market, offering a five-chip solution for the subscriber transceivers. The focus is on the local oscillator, the up-converter and the down converters at 40GHz. These two last chips include a balanced mixer, a buffer amplifier for the local oscillator and a low noise amplifier used either as a LNA (for Rx) or as a transmit driver (for Tx). The design was oriented toward low chip-size in order to reach the cost requirement for such systems. Results are shown from a demonstrator assembly built with these five MMICs.

Resonating valence bond states in the PEPS formalism

description: We study resonating valence bond (RVB) states in the Projected Entangled Pair States (PEPS) formalism. Based on symmetries in the PEPS description, we establish relations between the toric code state, the orthogonal dimer state, and the SU(2) singlet RVB state on the kagome lattice: We prove the equivalence of toric code and dimer state, and devise an interpolation between the dimer state and the RVB state. This interpolation corresponds to a continuous path in Hamiltonian space, proving that the RVB state is the four-fold degenerate ground state of a local Hamiltonian on the (finite) kagome lattice. We investigate this interpolation using numerical PEPS methods, studying the decay of correlation functions, the change of overlap, and the entanglement spectrum, none of which exhibits signs of a phase transition.

Adler-Bell-Jackiw anomaly in Weyl semi-metals: Application to Pyrochlore Iridates
Creators: name: Aji, Vivek
Publisher: name: arXiv
Year: 2011
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: Weyl semimetals are three dimensional analogs of graphene where the energy of the excitations are a linear function of their momentum. Pyrochlore Iridates $(A_{2}Ir_{2}O_{7})$ with A =yttrium or lanthanide element) are conjectured to be examples of such a system, with the low energy physics described by twenty four Weyl nodes. An intriguing possibility is that these materials provide a physical realization of the Adler-Bell-Jackiw anomaly. In this letter we investigate the properties of pyrochlore iridates in an applied magnetic field. We find that the dispersion of the lowest landau level depends on the direction of the applied magnetic field. As a consequence the magneto-conductivity in an electric field, applied parallel to the magnetic field is highly anisotropic, providing a detectable signature of the semi-metallic state.

description: manuscipt submitted under different title: “Simultaneous optimization of traffic congestion and noise exposures“
description: This study elaborates on the interrelation of external effects, in particular road traffic congestion and noise. An agent-based simulation framework is used to compute and internalize user-specific external congestion effects and noise exposures. The resulting user equilibrium corresponds to an approximation of the system optimum. For traffic congestion and noise, single objective optimization is compared with multiple objective optimization. The simulation-based optimization approach is applied to the real-world case study of the Greater Berlin area. The results reveal a negative correlation between congestion and noise. Nevertheless, the multiple objective optimization yields a simultaneous reduction in congestion and noise. During peak times, congestion is the more relevant external effect, whereas, during the evening, night and morning, noise is the more relevant externality. Thus, a key element for policy making is to follow a dynamic approach, i.e. to temporally change the incentives. During off-peak times, noise should be reduced by concentrating traffic flows along main roads, i.e. inner-city motorways. In contrast, during peak times, congestion is reduced by shifting transport users from the inner-city motorway to smaller roads which, however, may have an effect on other externalities.

description: This paper presents the design of a Local Oscillator for a new Broadband Access System based on Point to MultiPoint microwave Radio Links. The key advance is achieving good enough phase noise performance (100 dBc/Hz@100KHz), over a relatively wide frequency band (15%), with good pulling figure and harmonics suppression, at a low cost and small size, for volume production. A fully monolithic VCO/Prescaler solution, integrating the resonator, the reflection amplifier, a single-stage buffer amplifier, a divider by eight and all main bias circuitry into a 5.16 mm 2 GaAs chip has been developed. The development procedure set to make this possible, with specific emphasis to volume production issues, is hereby described. Some simulation and measured data are also reported. Moreover, some open issues and existing problems that still hinder first run design success are briefly discussed.

description: H Ευρωπαϊκή Επιτροπή τον Δεκέμβριο του 2019 παρουσίασε την Ευρωπαϊκή Πράσινη Συμφωνία, ένα σχέδιο δράσης με στόχο μια κλιματικά ουδέτερη Ευρώπη, απαλλαγμένη από την χρήση συμβατικών ορυκτών καυσίμων. Η συμφωνία βρίσκει εφαρμογή σε όλους τους τομείς της οικονομίας, από τη βιομηχανία και τις μεταφορές μέχρι τα τρόφιμα και τη γεωργία και επεκτείνεται στον κτιριακό τομέα, που αποτελεί έναν από τους μεγαλύτερους καταναλωτές ενέργειας και εκπομπών CO2.
Μέσα από τη στρατηγική «Κύμα Ανακαινίσεων» προωθούνται ανακαινίσεις δημόσιων και ιδιωτικών κτιρίων με σκοπό την αναβάθμιση της ενεργειακής απόδοσης και τον μηδενισμό των αέριων ρύπων τους. Στην παρούσα διπλωματική εργασία θα πραγματοποιηθεί μελέτη για την ενεργειακή αναβάθμιση του Συνεδριακού Κέντρου της Ορθόδοξης Ακαδημίας Κρήτης (ΟΑΚ) με στόχο τη μετατροπή του σε Κτίριο Σχεδόν Μηδενικής Κατανάλωσης σύμφωνα με τα πρότυπα της Ευρωπαϊκής Πράσινης Συμφωνίας. Πιο συγκεκριμένα, θα καθοριστούν σενάρια ενεργειακής αναβάθμισης που αφορούν στην κάλυψη των ενεργειακών αναγκών του κτιρίου της ΟΑΚ με ανανεώσιμες πηγές ενέργειας και θα πραγματοποιηθεί η ενεργειακή αξιολόγησή τους στη βάση κατάλληλων δεικτών ενεργειακής αποδοτικότητας. Στη συνέχεια θα πραγματοποιηθεί τεχνοοικονομική αξιολόγηση των σεναρίων, ώστε να επιλεχθεί αυτό που είναι οικονομικά αποδοτικότερο. Τέλος, θα παρουσιαστούν μελλοντικές προτάσεις ενεργειακής αναβάθμισης οι οποίες θα καλύπτουν τις βασικές αρχές της Πράσινης Συμφωνίας.

Dielectric Breakdown of a Mott Insulator

description: We study the nonequilibrium steady state of a Mott insulator coupled to a thermostat and driven by a constant electric field, starting from weak fields, until the dielectric breakdown, and beyond. We find that the conventional Zener picture does not describe the steady-state physics. In particular, the current at weak field is found to be controlled by the dissipation. Moreover, in connection with the electric-field-driven dimensional crossover, we find that the dielectric breakdown occurs when the field strength is on the order of the Mott gap of the corresponding lower-dimensional system. We also report a resonance and the meltdown of the quasiparticle peak when the field strength is half of this Mott gap.
