Subjects: ING-INF/01 Elettronica

description: In microwave applications, specific high performance packages have to be designed in order to reduce parasitic reflections, coupling effect... In this paper, the design of a package for microwave applications up to 12 GHz is presented. From the geometry of different leads and dielectric properties, an electromagnetic simulator is used to derive propagation characteristics. Results are discussed in terms of signal degradation, coupling and cross talk. Our analysis points out the stronger limitation of performance due to curved leads especially for high frequencies. The influence of the connection layout in the signal degradation for a transmission through the package and the cross coupling between leads are analyzed.

Is $1^-+$ Meson a Hybrid?

description: We calculate the vacuum to meson matrix elements of the dimension-4 operator $\barψγ_4\nblr_i ψ$ and dimension-5 operator $\barψ\epsγ_jψB_k$ of the $1^{-+}$ meson on the lattice and compare them to the corresponding matrix elements of the ordinary mesons to discern if it is a hybrid. For the charmoniums and strange quarkoniums, we find that the matrix elements of $1^{-+}$ are comparable in size as compared to other known $q\bar{q}$ mesons. They are particularly similar to those of the $2^{++}$ meson, since their dimension-4 operators are in the same Lorentz multiplet. Based on these observations, we find no evidence to support the notion that the lowest $1^{-+}$ mesons in the $c\bar{c}$ and $s\bar{s}$ regions are hybrids. As for the exotic quantum number is concerned, the non-relativistic reduction reveals that the leading terms in the dimension-4 and dimension-5 operators of $1^{-+}$ are identical up to a proportional constant and it involves a center-of-mass momentum operator of the quark-antiquark pair. This explains why $1^{-+}$ is an exotic quantum number in the constituent quark model where the center of mass of the $q\bar{q}$ is not a dynamical degree of freedom. Since QCD has gluon fields in the context of the flux-tube which is appropriate for heavy quarkoniums to allow the valence $q\bar{q}$ to recoil against them, it can accommodate such states as $1^{-+}$. By the same token, hadronic models with additional constituents besides the quarks can also accommodate the $q\bar{q}$ center-of-mass motion. To account for the quantum numbers of these $q\bar{q}$ mesons in QCD and hadron models in the non-relativistic case, the parity and total angular momentum should be modified to $P = (-)^{L + l +1}$ and $\vec{J} = \vec{L} + \vec{l} + \vec{S}$, where $L$ is the orbital angular momentum of the $q\bar{q}$ pair in the meson.

description: GaInNAs base layers are enabling performance enhancements over standard GaAs-based HBTs, while preserving the cost effective GaAs platform. We have demonstrated InGaP/GaInNAs HBTs which offer 115 mV lower operating voltage, improved diode symmetry for reduced VCE,offset and Vknee, and superior gain temperature stability as compared with standard InGaP/GaAs HBTs. These enhancements have been realized while simultaneously preserving DC current gain and base doping ( ββ β80, Rsb 530 Ω/†, base thickness -500 Å, base doping ~ 4×10 19 cm 2 ) at the high levels necessary for commercial applications. GaInNAs enables these performance enhancements due to a lower energy gap which advantageously alters relative magnitudes of the collector and various base current components in an HBT.

description: Correlation between chemical and electrical properties of n-InGaP surfaces grown by metal-organic chemical vapor epitaxy (MOVPE) was investigated by x-ray photoelectron spectroscopy (XPS), current-voltage (I-V) and UHV contactless capacitance-voltage (C-V) methods. An air-exposed surface exhibited highly In-rich phase where the InPO 4 -like natural oxide was dominant. Poor I-V characteristics appeared in Schottky contacts fabricated on the air-exposed surfaces. Chemical treatments in HCl and HF solutions were found to be effective in reducing natural oxide and in recovering the surface stoichiometry. The UHV contactless C-V results showed no pronounced Fermi level pinning at the chemically treated InGaP surfaces. Furthermore, such treatments improved Schottky I-V properties.
Time Reversal Violation from the entangled B0-antiB0 system

description: We discuss the concepts and methodology to implement an experiment probing directly Time Reversal (T) non-invariance, without any experimental connection to CP violation, by the exchange of "in" and "out" states. The idea relies on the B0-antiB0 entanglement and decay time information available at B factories. The flavor or CP tag of the state of the still living neutral meson by the first decay of its orthogonal partner overcomes the problem of irreversibility for unstable systems, which prevents direct tests of T with incoherent particle states. T violation in the time evolution between the two decays means experimentally a difference between the intensities for the time-ordered (l^+ X, J/psi K_S) and (J/psi K_L, l^- X) decays, and three other independent asymmetries. The proposed strategy has been applied to simulated data samples of similar size and features to those currently available, from which we estimate the significance of the expected discovery to reach many standard deviations.

description: We describe how regularization of lattice Boltzmann methods can be achieved by modifying dissipation. Classes of techniques used to try to improve regularization of LBMs include flux limiters, enforcing the exact correct production of entropy and manipulating non-hydrodynamic modes of the system in relaxation. Each of these techniques corresponds to an additional modification of dissipation compared with the standard LBGK model. Using some standard 1D and 2D benchmarks including the shock tube and lid driven cavity, we explore the effectiveness of these classes of methods.

A qualitative study : community nurses' experience of organizational trust
Creators: name: Calvin, Leanne
Publisher: name: University of British Columbia
Year: 2014

description: This qualitative inquiry explored nurses’ experience of organizational trust and factors that influence it within a community health context. The study aims were to provide awareness to health organizations as to how they may avoid negative impacts of decreased trust of community nurses' and increase the likelihood of positive acceptance of changing health services and a restructured organization. The British Columbia healthcare system is becoming more reliant on the community nursing sector to address increasing demands in healthcare due to several factors such as an aging population, rise in chronic diseases, and limited financial and human resources. If community nurses do not have trust in the health organization, there may be resistance to changes that have been designed to improve health services. This may result in poorer health outcomes for the population and increased burden on the acute care system. Health organizations that are not aware of factors that may influence community nurses’ organizational trust may encounter higher rates of job turnover, decreased productivity, and challenges in maintaining a viable healthcare system. A qualitative design with an interpretative description approach was used along with theoretical concepts pertaining to organizational trust. Community nurses within the interior region of British Columbia, Canada received invitations to participate via email. Data collection involved semi-structured interviews with 10 participants which were digitally recorded and transcribed professionally. Three main themes identified were 1) leadership support 2) organizational restructure 3) evolving health services and practices. These main themes yielded the following conclusions: that nurses’ perception of leadership support, particularly nurse-leader relationships can significantly influence their trust in the health organization; and that nurses’ lack of participation in decision-making during change can negatively impact their trust in the health organization. The major implications that arose from this study include: 1) implications for leadership to implement strategies to improve interpersonal relationships with nurses, collaborative change processes and a shared vision, opportunities for nurses to engage with organizational structures; 2) implications for practice to include nurses in decision-making and utilize change models; 3) implications for policy to have a nurse representative at the senior level of leadership.

description: We outline a straightforward approach for obtaining a secret key rate using only no-signaling constraints and linear programming. Assuming an individual attack, we consider all possible joint probabilities. Initially, we study only the case where Eve has binary outcomes, and we impose constraints due to the no-signaling principle and given measurement outcomes. Within the remaining space of joint probabilities, by using linear programming, we get bound on the probability of Eve correctly guessing Bob's bit. We then make use of an inequality that relates this guessing probability to the mutual information between Bob and a more general Eve, who is not binary-restricted. Putting our computed bound together with the Csiszár-Körner formula, we obtain a positive key generation rate. The optimal value of this rate agrees with known results, but was calculated in a more straightforward way, offering the potential of generalization to different scenarios.

description: We construct a fully equivariant correspondence between Gromov-Witten and stable pairs descendent theories for toric 3-folds X. Our method uses geometric constraints on descendents, A_n surfaces, and the topological vertex. The rationality of the stable pairs descendent theory plays a crucial role in the definition of the correspondence. We prove our correspondence has a non-equivariant limit. As a result of the construction, we prove an explicit non-equivariant stationary descendent correspondence for X (conjectured previously by MNOP). Using descendent methods, we establish the relative GW/Pairs correspondence for X/D in several basic new log Calabi-Yau geometries. Among the consequences is a rationality constraint for non-equivariant descendent Gromov-Witten series for P^3.

description: The strong spontaneous and piezoelectric polarizations in pseudomorphic AlGaN/GaN on SiC substrates are used to induce 2DEG sheet density of > 1 x 10 13 /cm 2 with mobility up to 1,700 cm 2 /vs. The processing sequence and HEMT electrode layout are presented. The output power and power-added efficiency in the 8-10 GHz frequency range are shown for CW bias conditions and optimum tuning in class B operation. Single-gate, center-fed 100 µm periphery devices gave 11.2 W/mm at 32% power-added efficiency; two-gate, 200 µm periphery devices with 50 µm pitch gave 8.7 W/mm at 48% power-added efficiency, and 12-gate, 1.5 mm periphery devices with 50 µm pitch gave 6.7 W/mm at 42% power-added efficiency. For comparison, the latter gave 9.4 W/mm at 43% power-added efficiency in low duty cycle pulsed operation . The key limitation for CW power performance is self-heating, which raises the knee voltage by (T/300) 1.8 for T channel temperature in °K.

description: Let p be an odd prime, and k_\infty the cyclotomic Z_p-extension of an abelian field k. For a finite set S of rational primes which does not include p, we will consider the maximal S-ramified abelian pro-p extension M_S(k_\infty) over k_\infty. We shall give a formula of the Z_p-rank of Gal(M_S(k_\infty)/k_\infty). In the proof of this formula, we also show that M_{q}(k_\infty)/L(k_\infty) is a finite extension for every real abelian field k and every rational prime q distinct from p, where L(k_\infty) is the maximal unramified abelian pro-p extension over k_\infty.

description: Based upon the active line concept, the conversion mechanisms of microscopic low frequency noise (e.g. generation-recombination noise) located in the channel of a Field Effect Transistor (FET) which is driven by a large RF signal is demonstrated. The first consequence is that the based band (low frequency) input gate noise voltage spectral density is dependent on the magnitude of the input RF power applied to the FET. Moreover, the microscopic generation-recombination noise sources located in the channel are responsible of up-converted input gate noise voltage spectral density around the RF frequency.

description: High-performance measuring multi-port 3-level fixture for active device characterization in the Ku-band is described in this paper. It is a low-cost alternative of the expensive microwave "on-wafer" measurements with CPW probes. The method of modeling of the separate components of the each embedding RF-path of the fixture is used for de-embedding purposes. Testing of several phantom-type structures on the chip-carrier level confirms the ability of the considered fixture to give repeatable results for the extracted own MMIC's parameters: mainly for the insertion phase and the gain.

description: Die genetische Karte zeigt häufige Abweichungen der Marker-Positionen in Vergleich zur physikalischen Karte, besonders im Zentromerbereich. Um dieses Problem in der Gerste zu lösen, wurden 70 Einzelkopie-Sonden des Chromosoms 3H aus dem 5,5 cM langen Zentromerbereich abgeleitet und mittels Fluoreszenz in situ Hybridisierungkartiert. Die physikalische Länge des genetischen Zentromers vom mitotischen Metaphasenchromosom 3H der Gerste umfasst 58% des physischen Chromosoms. Die Analyse von posttranslationalenHiston H3-Modifikationen zeigt, dass die Rekombinationshäufigkeit mit einer bestimmten Chromatinstruktur korreliert. Mithilfe der Kartierung von chromosomenspezifischen Einzelkopie-Sonden auf verwandten Arten der kultivierten Gerste wurde eine hohe Ähnlichkeit zwischen den zu vier verschiedenen Subgenomen zugehörenden untersuchten Arten der Gattung Hordeum nachgewiesen. Die Unterschiede in Markerpositionen zwischen untersuchten Arten können entweder auf die konservierten, jedoch nicht kollinearen Gene im Tribus Triticeae zurückgeführt werden, oder auf subchromosomale Translokationen innerhalb Hordeum hinweisen.
description: Genetic maps often show different positions of molecular markers in comparison to physical maps, particularly in the centromere. To decipher the position and order of DNA sequences genetically mapped to the centromere of barley’s chromosome 3H, fluorescence in situhybridization was performed with 70 genomic single-copy probes derived from 65 fingerprinted BAC contigs genetically assigned to this region. The total physical distribution of the centromeric 5.5 cM bin of 3H comprises 58% of the chromosome length. The analysis of posttranslational histone H3 modifications makes clear that more than the half of the physical length of chromosome 3H is associated with reduced recombination. Comparative FISH mapping of chromosome-specific single copy probes in related species demonstrated a high degree of similarity at the chromosomal level among Hordeum species from different subgenome groups. Detected positional differences within Hordeum occurred either due toconserved, but non-collinear genes among Triticeae, or to small-scale chromosomal rearrangements.

description: We use HST/WFC3 imaging from the CANDELS Multicycle Treasury Survey, in conjunction with the Sloan Digital Sky Survey, to explore the evolution of galactic structure for galaxies with stellar masses >3e10M_sun from z=2.2 to the present epoch, a time span of 10Gyr. We explore the relationship between rest-frame optical color, stellar mass, star formation activity and galaxy structure. We confirm the dramatic increase from z=2.2 to the present day in the number density of non-star-forming galaxies above 3e10M_sun reported by others. We further find that the vast majority of these quiescent systems have concentrated light profiles, as parametrized by the Sersic index, and the population of concentrated galaxies grows similarly rapidly. We examine the joint distribution of star formation activity, Sersic index, stellar mass, inferred velocity dispersion, and stellar surface density. Quiescence correlates poorly with stellar mass at all z<2.2. Quiescence correlates well with Sersic index at all redshifts. Quiescence correlates well with `velocity dispersion' and stellar surface density at z>1.3, and somewhat less well at lower redshifts. Yet, there is significant scatter between quiescence and galaxy structure: while the vast majority of quiescent galaxies have prominent bulges, many of them have significant disks, and a number of bulge-dominated galaxies have significant star formation. Noting the rarity of quiescent galaxies without prominent bulges, we argue that a prominent bulge (and perhaps, by association, a supermassive black hole) is an important condition for quenching star formation on galactic scales over the last 10Gyr, in qualitative agreement with the AGN feedback paradigm.

description: The question of whether hydrogen atoms can exist or not in spaces with a number of dimensions greater than 3 is revisited, considering higher dimensional Euclidean spaces. Previous results which lead to different answers to this question are briefly reviewed. The scenario where not only the kinematical term of Schrödinger equation is generalized to a D-dimensional space but also the electric charge conservation law (expressed here by the Poisson law) should actually remains valid is assumed. In this case, the potential energy in the Schrödinger equation goes like 1/r^{D-2}. The lowest quantum mechanical bound states and the corresponding wave functions are determined by applying the Numerov numerical method to solve Schrödinger's eigenvalue equation. States for different angular momentum quantum number (l = 0; 1) and dimensionality (5 \leq D \leq 10) are considered. One is lead to the result that hydrogen atoms in higher dimensions could actually exist. For the same range of the dimensionality D, the energy eigenvalues and wave functions are determined for l = 1. The most probable distance between the electron and the nucleus are then computed as a function of D showing the possibility of tiny bound states.

description: The Non-Linear Scattering Functions have been theoretically defined and experimentally measured for the linear-equivalent design of non-linear circuits in arbitrary large signal conditions. Non-linear measures and simulations have been compared, with good agreement. Linear CAD concepts can therefore be extended to non-linear circuits in a rigorous way.
Cellular and molecular mechanisms of action of NR2E1 in eye development
Creators: name: Corso-Díaz, Ximena
Publisher: name: University of British Columbia

description: NR2E1 is a highly conserved orphan nuclear receptor crucial for neural stem cell proliferation and maintenance during development and adulthood. Nr2e1-null mice have brain and eye malformations, display cognitive deficits, are aggressive, and blind. NR2E1 regulatory variants have been found in bipolar disorder and cortical malformations in humans. Complete understanding of NR2E1 action requires identification of genes regulated by NR2E1, protein partners including co-regulators that interact with NR2E1, and characterization of the loci where these interactions take place. Importantly, the mechanisms of action and regulation of NR2E1, and its role in human pathology remain poorly understood. In this thesis, I studied the role of NR2E1 in three different systems. First, I explored the potential role of NR2E1 mutations in patients with aniridia and other congenital ocular disorders. I found that mutations in NR2E1 do not play a role in aniridia and provided further evidence on the high genetic conservation of NR2E1 in the human population. Second, I studied the cell-autonomous and non-cellautonomous roles of Nr2e1 in retinal development using Nr2e1-null mice, and chimeric mice comprised of both wild-type and Nr2e1-null cells. I found that Nr2e1 regulates the development of specific retinal cell types and the organization of the neurites of inner nuclear neurons. Third, I studied NR2E1 at the protein level by screening for NR2E1 co-regulators using a peptide array and affinity purification tools. I found that the ligand binding domain of NR2E1 interacts with 19 putative novel co-regulators in vitro, and that most of these interactions are lost with the NR2E1 variant R274G, which I showed, does not affect gross retinal development in vivo. Overall, this study furthers our knowledge on the roles and mechanisms of action of NR2E1 during eye development by ruling out its role in a human eye disorder, demonstrating its role in mouse retinal cell development and lamination, and unraveling some of its potential co-regulatory partners. Future studies are necessary to better characterize the role of NR2E1 in cell development and neurite organization as well as its interaction with the co-regulators herein discovered during retinal and brain development.

description: In dieser Arbeit wird eine neues Konzept zur Untersuchung und Auswertung der radialen Wärmetransportverhältnisse in gasdurchströmten Rohrreaktoren auf der Grundlage instationärer Messungen vorgestellt. Hierdurch war es möglich im Vergleich zu bekannten stationären Untersuchungsansätzen eine Erhöhung des Informationsgehaltes der experimentellen Daten, insbesondere im für die Gaskatalyse typischen Bereich kleiner D/d-Verhältnisse und geringer Durchströmung, zu erzielen. Dadurch konnten die in der Literatur umstrittenen Wärmetransportverhältnisse an der Rohrinnwand aufgeklärt sowie empirische Korrelationen für die Parameter des zweidimensionalen, quasihomogenen Pfropfenströmungsmodell abgeleitet werden, die eine deutlich genauere Wiedergabe der eigenen Messungen als bekannte Ansätze erlauben. Außerdem wurde die Änderung des Wärmetransportverhaltens des Festbettes beim Übergang von Kugeln zu Hohlzylindern untersucht.
description: A novel concept for the investigation and evaluation of radial heat transfer in tubular reactors in absence of a chemical reaction based on instationary measurements is presented in this work. Compared to known stationary investigational concepts one is able to get an increased informational yield from the experimental data especially for low tube-to-particle diameter ratios and small gas mass flow rates to be found typically in heterogeneous catalysis. The question discussed contrary in literature which boundary condition should be applied to the inner reactor wall is answered. A empirical correlation of the parameters for the two dimensional pseudohomogeneous model was found which allows a more accurate description of the experimental findings than known approaches from literature. The experiments were conducted for spherical particles and hollow cylinders made from steatite.

description: Ratio asymptotics for matrix orthogonal polynomials with recurrence coefficients $A_n$ and $B_n$ having limits $A$ and $B$ respectively (the matrix Nevai class) were obtained by Durán. In the present paper we obtain an alternative description of the limiting ratio. We generalize it to recurrence coefficients which are asymptotically periodic with higher periodicity, and/or which are slowly varying in function of a parameter. Under such assumptions, we also find the limiting zero distribution of the matrix orthogonal polynomials, generalizing results by Durán-López-Saff and Dette-Reuther to the non-Hermitian case. Our proofs are based on "normal family" arguments and on the solution to a quadratic eigenvalue problem. As an application of our results we obtain new explicit formulas for the spectral measures of the matrix Chebyshev polynomials of the first and second kind, and we derive the asymptotic eigenvalue distribution for a class of random band matrices generalizing the tridiagonal matrices introduced by Dumitriu-Edelman.

description: In this paper, we present some non exhaustive measurement techniques used for characterization and modeling of high power devices. Capabilities offered by pulsed measurements can be an efficient approach to deal with self-heating effects and sometimes trapping effects encountered in microwave high power devices. Pulsed techniques allow to separate self-heating and trapping effects, making like this the modeling process easier. A pulsed RF and pulsed bias load-pull system is then described as well as a time waveform measurement system. Capabilities of these two characterization tools are illustrated with results obtained on a high power silicon bipolar transistor and on a GaAs MESFET device.

description: From the deep-sea-derived bacterium Bacillus subterraneus 11593, a new indole alkaloid (1) was isolated along with three known compounds (2‒4). By detailed analysis of its NMR spectroscopic data, and further by the theoretical ECD calculations, the absolute configuration of the new compound was determined to be (R)-N-[2-(3-hydroxy-2-oxoindolin-3-yl)ethyl]acetamide, and named bacilsubteramide A. All four isolates were tested for anti-allergic bioactivities; however, none exhibited positive effect (IC50 > 0.2 mM). Noteworthily, it is the first report on secondary metabolites from the bacterium B. subterraneus.

description: We propose a new simple and accurate method for the higher order Taylor coefficient extraction of the channel current in GaAs MESFET. In this method, the nonlinear channel currents are directly measured through a hole current sensor and spectrum analyzer. Taylor coefficients up to 3rd order have been successfully extracted from the measured currents of the low frequency(4MHz, 25MHz) two-tone test, and a resonator is added to the load to remove the gate frequency component from the drain voltage, which makes the problem simple. The proposed extraction procedure is simple and straightforward.
