description: We study the market impact of a meta-order in the framework of the Minority Game. This amounts to studying the response of the market when introducing a trader who buys or sells a fixed amount h for a finite time T. This perturbation introduces statistical arbitrages that traders exploit by adapting their trading strategies. The market impact depends on the nature of the stationary state: We find that the permanent impact is zero in the unpredictable (information efficient) phase, while in the predictable phase it is non-zero and grows linearly with the size of the meta-order. This establishes a quantitative link between information efficiency and trading efficiency (i.e. market impact). By using statistical mechanics methods for disordered systems, we are able to fully characterize the response in the predictable phase, to relate execution cost to response functions and obtain exact results for the permanent impact.

description: We report the results of a phase-shift analysis (PSA) of the low-energy $π^\pm p$ elastic-scattering data. Following the method which we had set forth in our previous PSA (Matsinos et al., 2006), we first investigate the self-consistency of the low-energy $π^\pm p$ elastic-scattering databases, via two separate analyses of (first) the $π^+ p$ and (subsequently) the $π^- p$ elastic-scattering data. There are two main differences to our previous PSA: a) we now perform only one test for the acceptance of each data set (based on its contribution to the overall $χ^2$) and b) we adopt a more stringent acceptance criterion in the statistical tests. We show that it is possible to obtain self-consistent databases after removing a very small amount of the data (4.57% of the initial database). We subsequently fit the ETH model (Goudsmit et al. 1994) to the truncated $π^\pm p$ elastic-scattering databases. The model-parameter values show reasonable stability when subjected to different criteria for the rejection of single data points and entire data sets. Our result for the pseudovector $πN N$ coupling constant is $0.0726 \pm 0.0014$. We extract the scattering lengths and volumes, as well as the s- and p-wave hadronic phase shifts up to T=100 MeV. Large differences in the s-wave part of the interaction can be seen when comparing our hadronic phase shifts with the current SAID solution (WI08); there is general agreement in the p waves, save for the $\tildeδ_{1-}^{1/2}$ hadronic phase shift.

description: This paper reports on the growth, patterning, and
characterization of plasma-enhanced chemical vapor deposition
(PECVD) thin diamond film for DC-65 GHz applications.
Nanocrystalline films are successfully demonstrated with an average
grain size of less than 60 nm that can replace conventional
low-quality dielectrics in RF MEMS switches. In addition to
their excellent surface properties, the diamond film has negligible
RF loss up to at least 65 GHz, but non-zero DC conductivity
of approximately 0.2 μS/m that allows the film to provide a
conductive path for potential trapped charges. Such films are
envisioned to be integrated in today’s capacitive RF MEMS
switches that suffer from charge-induced stiction.

description: This paper examines how contextual variables can explain the significant gap in performance for unsupervised modeling of tones in Tai Khamti [ISO 639-3: kht] spoken in Myanmar. Two corpora were extracted from citation tones and tones in running speech in order to assess the utility and limitations of these methods. Taking native judgments as ground truth, current results show high precision on citation tones, between 0.93 and 1.0, in three of the four expected tonal categories, as well as recall 0.79-0.86 in all four. Tones in sentential contexts showed precision just 0.28-0.62, with recall between 0.21 and 0.63.

description: Transceiver designs implemented in silicon
technology are most competitive in design cycle-time and
performance versus cost when compared to other technologies.
Scaling is driving silicon technology towards gain-bandwidths
of 300GHz, enabling circuits operating deep into
mm-wave frequency bands (i.e., well above 30 GHz). However,
innovations in on-chip passive design and construction
currently being pioneered in mixed-signal silicon technologies
may be the real technology enablers at these frequencies.

description: Colin Pennycuick was almost single-handedly responsible for the successful, and continuing, merger of the engineering and mathematical sciences of aerodynamics and flight mechanics with ornithology, ecology and bird flight behaviour. He developed a mathematical/aerodynamical/ecological model of bird flight that could explain and predict bird body and wing shapes and sizes, and hence flight behaviour over a broad range of length- and time-scales, for real birds. He sought to bring rigorous quantitative methods to the people, and insisted that no matter how complex and sophisticated a theoretical model may be, unless it showed some improvement and advance in its practical utility, then it was of questionable value. He similarly insisted that model predictions be testable, and that results be openly and quantifiably given. His approach was marked by two distinct characteristics: first he pioneered the use of small aircraft and powered and unpowered gliders to follow soaring and migrating birds in their natural environment, exploiting his top-level pilot skills; second, he invented, designed and built novel instrumentation for making hitherto unheard-of laboratory and field measurements. The most well-known were his tilting wind tunnels, in which birds and bats could be trained to perform steady gliding flight. His intellectually and geographically-broad range of interests and contacts led to his being a giant influence in theoretical and practical bird flight mechanics and behaviour, one that is likely to stay with us for many decades.
Entanglement Entropy of Fermi Liquids via Multi-dimensional Bosonization

description: The logarithmic violations of the area law, i.e. an "area law" with logarithmic correction of the form $S \sim L^{d-1} \log L$, for entanglement entropy are found in both 1D gapless system and for high dimensional free fermions. The purpose of this work is to show that both violations are of the same origin, and in the presence of Fermi liquid interactions such behavior persists for 2D fermion systems. In this paper we first consider the entanglement entropy of a toy model, namely a set of decoupled 1D chains of free spinless fermions, to relate both violations in an intuitive way. We then use multi-dimensional bosonization to re-derive the formula by Gioev and Klich [Phys. Rev. Lett. 96, 100503 (2006)] for free fermions through a low-energy effective Hamiltonian, and explicitly show the logarithmic corrections to the area law in both cases share the same origin: the discontinuity at the Fermi surface (points). In the presence of Fermi liquid (forward scattering) interactions, the bosonized theory remains quadratic in terms of the original local degrees of freedom, and after regularizing the theory with a mass term we are able to calculate the entanglement entropy perturbatively up to second order in powers of the coupling parameter for a special geometry via the replica trick. We show that these interactions do not change the leading scaling behavior for the entanglement entropy of a Fermi liquid. At higher orders, we argue that this should remain true through a scaling analysis.

Robust and fast T2 decay analysis for measuring myelin water in MRI
Creators: name: Yoo, Youngjin
Publisher: name: University of British Columbia
Year: 2013

description: Myelin is an essential component of nerve fibers and monitoring its health is important for studying neurological diseases that attack myelin, such as multiple sclerosis. The amount of water trapped within myelin, which is a surrogate for myelin content and integrity, can be measured in vivo using MRI relaxation techniques that acquire a series of images at multiple echo times to produce a T₂ decay curve at each voxel. These curves are then analyzed, most commonly using non-negative least squares (NNLS) fitting, to produce T₂ distributions from which water measurements are made. T₂ decay analysis using NNLS has two main challenges: instability and high computational demands. The main contributions of this thesis are: 1) we propose a new regularization algorithm in which local and non-local information is gathered and used adaptively for each voxel and 2) we propose a hybrid utilization method of multicore CPUs and GPUs to improve the efficiency of a T₂ decay analysis, with consideration of the increased computational burden of regularization and careful analysis of which algorithmic components would benefit from multicore CPU vs. GPU parallelization. Our results demonstrated that the proposed regularization method provided more globally consistent myelin water measurements, yet preserved fine structures. Our experiment with real patient data suggested that the algorithm improved the reproducibility and the ability to distinguish between the myelin maps of multiple sclerosis patients and healthy subjects. We also demonstrated our optimized implementation’s performance by comparing with a parallelized implementation written in MATLAB which is the most commonly used platform for the analysis of T₂ relaxation data. We found an improvement in speed of over 4× when computing single seven-slice myelin map and over 14× for a batch processing using the same number of CPU cores.

description: We study the optical orientation of electron spins in GaAs/AlGaAs quantum wells for excitation in the growth direction and for in-plane excitation. Time- and polarization-resolved photoluminescence excitation measurements show, for resonant excitation of the heavy-hole conduction band transition, a negligible degree of electron spin polarization for in-plane excitation and nearly 100% for excitation in the growth direction. For resonant excitation of the light-hole conduction band transition, the excited electron spin polarization has the same (opposite) direction for in-plane excitation (in the growth direction) as for excitation into the continuum. The experimental results are well explained by an accurate multiband theory of excitonic absorption taking fully into account electron-hole Coulomb correlations and heavy-hole light-hole coupling.

description: The New Jersey Energy Master Plan Phase I Report provides a framework for managing the transition of the State's natural gas and electric power industries from markets guided by the regulation of monopolies to chose guided by market-based principles and competition. The Plan enunciates standards which ensure continued consumer protection as New Jersey moves toward more competitive markets. The Plan recommends the adoption of:1. rate flexibility as a short-term or interim measure which allows utilities to compete in order to retainand attract customers in a changing regulatory environment;2. alternative regulation as an interim and possibly as a long-term measure which allows market forces to stimulate efficiency, productivity and innovation; 3. significant consumer protection standards to ensure that captive ratepayers do not subsidize competitiveactivities and to ensure that all ratepayers benefit from the transition to greater competition; and,4. integrated resource planning and a competitive supply side procurement process as interim measures tostreamline the regulatory review process, lower costs to all ratepayers through increased competition, and ensure that the State's environmental and energy conservation goals are met in a competitive marketplace.

applications. The integration is based on the System In
Package (SiP) approach achieving high performances and
integration density level at microwave and millimeterwave
frequencies thanks to the mixing of state-of–the-art
technologies both for active (SiGe or RF-MOS
technologies) and passive (dielectric based technology)
devices/circuits. This concept can also take full benefit of
the MEMS technologies to provide various smart
functionalities to microsystem. The proposed approach is
illustrated through different applications which outline
the design issues of such heterogeneous microsystem.

description: Recent hydrostatic X-ray studies of the hot interstellar medium (ISM) in early-type galaxies underestimate the gravitating mass as compared to stellar dynamics, implying modest, but significant deviations from exact hydrostatic equilibrium. We present a method for combining X-ray measurements and stellar dynamical constraints in the context of Bayesian statistics that allows the radial distribution of the implied nonthermal pressure or bulk motions in the hot ISM to be constrained. We demonstrate the accuracy of the method with hydrodynamical simulations tailored to produce a realistic galaxy model. Applying the method to the nearby elliptical galaxy NGC4649, we find a significant but subdominant nonthermal pressure fraction (0.27+/-0.06) in the central (<5 kpc) part of the galaxy, similar to the level of deviations from hydrostatic equilibrium expected in galaxy clusters. Plausible sources of systematic error, if important, may reduce this fraction. This would imply >360 km/s random turbulence or a magnetic field B=(39+/-6)(n_e/0.1 cm^{-3})^{0.59+/-0.09} muG, whereas gas rotation alone is unlikely to explain the detailed nonthermal profile. Future observations with Astro-H will allow turbulence or gas rotation at this level to be detected.

description: In den letzten Jahrzehnten wurde sowohl die Biosynthese der Jasmonsäure (JA) aufgeklärt, als auch die umfangreichen Wirkungen von JA während der Reaktion auf biotischen und abiotischen Stress und während der pflanzlichen Entwicklung vielfältig analysiert. Weitaus weniger ist hingegen über die verschiedenen Metabolite von JA bekannt. Ziel dieser Arbeit war die funktionale Charakterisierung der JA-Metabolite 12-OH- JA, 12-HSO4-JA und 12-O-Gluc-JA. Das differentielle Vorkommen dieser Metabolite konnte in verschiedenen Pflanzen gezeigt werden. Mit Hilfe von Tomaten-Mutanten konnte die Abhängigkeit der Bildung der drei JA-Metabolite von einer vollständigen JA-Biosynthese belegt werden. Die im Vergleich zu JA fehlende Hemmung von Wurzelwachstum und Keimung sowie die Repression JA-responsiver Gene durch 12-OH-JA und 12-HSO4-JA deuten auf ein Abschalten des JA-Signals durch Metabolisierung hin. Ein weiteres Ziel dieser Arbeit bestand in der Manipulation des 12-OH-JA-, 12-HSO4-JA- und 12-O-Gluc-JA-Gehaltes in planta mit Hilfe transgener Ansätze. Nach Überexpression der 12-OH-JA-Sulfotransferase aus Arabidopsis thaliana (AtST2a) in Tomate konnte u.a. ein erhöhter 12-HSO4-JA-Gehalt nachgewiesen werden. Entsprechende Pflanzen zeigten eine veränderte Infloreszenz-Morphologie. Dies unterstreicht die Bedeutung des JA-Metabolismus bzw. der JA-Metabolite für die pflanzliche Entwicklung.
description: The biosynthesis of jasmonic acid (JA) as well as various effects of JA on plant growth and the reaction on different stresses was elucidated during the last decades. In contrast only little is known about the biological function of naturally occurring derivatives of JA. The aim of this work was the functional characterisation of the JA metabolites 12-OH-JA, 12-HSO4-JA and 12-O-Gluc-JA. The differential occurrence of these metabolites could be shown for various plant species. Analysis of tomato mutants demonstrated the dependence of the generation of the JA metabolites on a complete JA biosynthesis. One further aim was the manipulation of 12-OH-JA, 12-HSO4-JA and 12-O-Gluc-JA contents in planta using transgenic approaches. Following overexpression of the 12-OH-JA sulfotransferase from Arabidopsis thaliana in tomato an increase of the 12-HSO4-JA level and a decrease of the 12-OH-JA as well as the 12-O-Gluc-JA level in conjunction with an altered inflorescence phenotype was observed. This demonstrates the impact of JA metabolism on plant development.

description: This paper reviews the relevance of the
widely used device metrics fT, fmax as well as the recently
introduced device metrics fA and fcross for broadband circuit
design. Usually, IC processes are benchmarked on the basis
of their fT and fmax. For most circuit applications however,
there is only an indirect relation between fT, fmax and circuit
bandwidths. Since the differential pair amplifier is a key
building block in broadband circuits, the metric fA provides
a nearly direct relation to broadband circuit performance.
This is demonstrated via the maximum operating frequency
of a current-mode logic frequency divider, processed in 3
generations of a BiCMOS process. Metric fcross is valuable
for the design of circuits employing a cross-coupled
differential pair as active negative resistance, such as in LCVCOs.
The metrics can be expressed in terms of transistor
parameters (e.g., Rb, Cbc, …), allowing to derive a link
between circuit performance and technology. Based on our
experience, we evaluate IC processes on the basis of fT, fA
and fcross rather than fT and fmax.

description: We consider a boson gas on the stretched horizon of the Schwartzschild and Kerr black holes. It is shown that the gas is in a Bose-Einstein condensed state with the Hawking temperature $T_c=T_H$ if the particle number of the system be equal to the number of quantum bits of space-time $ N \simeq {A}/{ł_{p}^{2}}$. Entropy of the gas is proportional to the area of the horizon $(A)$ by construction. For a more realistic model of quantum degrees of freedom on the horizon, we should presumably consider interacting bosons (gravitons). An ideal gas with intermediate statistics could be considered as an effective theory for interacting bosons. This analysis shows that we may obtain a correct entropy just by a suitable choice of parameter in the intermediate statistics.

description: The low resistivity substrate that is used in
bulk silicon processes (CMOS and BiCMOS) limits the
integration of high-quality passives components and gives
rise to severe substrate coupling issues. This paper will show
how to take advantage of HR SOI to improve RF circuit
performances as well as the effectiveness of HR SOI to
reduce substrate coupling. Potentiality of mm-wave passive
integration is also shown.
Two-dimensional chiral crystals in the NJL model

description: We investigate the phase structure of the Nambu--Jona-Lasinio model at zero temperature, allowing for a two-dimensional spatial dependence of the chiral condensate. Applying the mean-field approximation, we consider various periodic structures with rectangular and hexagonal geometries, and minimize the corresponding free energy. We find that these two-dimensional chiral crystals are favored over homogeneous phases in a certain window in the region where the phase transition would take place when the analysis was restricted to homogeneous condensates. It turns out, however, that in this regime they are disfavored against a phase with a one-dimensional modulation of the chiral condensate. On the other hand, we find that square and hexagonal lattices eventually get favored at higher chemical potentials. Although stretching the limits of the model to some extent, this would support predictions from quarkyonic-matter studies.

description: The efficiency at maximum power (EMP) of irreversible Carnot-like heat engines is investigated based on the weak endoreversible assumption and the phenomenologically irreversible thermodynamics. It is found that the weak endoreversible assumption can reduce to the conventional one for the heat engines working at maximum power. Carnot-like heat engines are classified into three types (linear, superlinear, and sublinear) according to different characteristics of constitutive relations between the heat transfer rate and the thermodynamic force. The EMPs of Carnot-like heat engines are proved to be bounded between $η_C/2$ and $η_C/(2-η_C)$ for the linear type, 0 and $η_C/(2-η_C)$ for the superlinear type, and $η_C/2$ and $η_C$ for the sublinear type, respectively, where $η_C$ is the Carnot efficiency.

description: For the first time this paper presents strip lines fabricated using SU-8 as the dielectric material. It shows the complete fabrication process of micromachined strip lines with a total height of as well as their characterization by on-wafer S-parameter measurements with frequencies up to the mm-wave range. Strip lines with a a strip thickness of , a line length of 3mm and variations of strip width between 6 and were manufactured and measured. The characteristic impedance, the phase constant, the phase velocity and the attenuation onstant of the lines were determined from the measured S-parameters. Characteristic impedance values between and were measured and on the strip line an attenuation constant of and at and respectively were determined. Since the fabricated strip line is totally shielded and its dielectric consists solely of SU-8, determination of the relative dielectric constant and the loss tangent of SU-8 was performed from microwave measurements on the strip lines. A relative dielectric constant of 1 and a loss tangent of for SU-8 was determined.
Spatial curvature and cosmological tests of general relativity

description: It is well-known that allowing for spatial curvature affects constraints on cosmological parameters such as the dark energy equation of state parameters. Here we study the effect of curvature on constraints on parameters used to test general relativity (GR) at cosmological scales, commonly known as modified growth (MG) parameters, as while current data taken in the context of the $Λ$CDM model points to a universe that is flat or very close to it, this constraint may not hold in modified theories of gravity. Using the latest cosmological data sets we find that MG parameters are correlated with the curvature parameter $Ω_k$ and the constraints on the MG parameters are weakened compared to when $Ω_k$ is not included in the parameter analysis. We next use various future simulated data sets, including cosmic microwave background, weak lensing, and Integrated Sachs-Wolfe-galaxy cross-correlations, where the fiducial model is spatially curved but we assume a flat model when fitting the MG parameters. We find the assumption of a spatially flat model on a spatially curved universe does indeed cause an artificial shift in the constraints on the MG parameters, in some cases even producing an apparent deviation from GR in the MG parameter space. For our simulated data, tension with GR begins to manifest itself for fiducial models with $\abs{Ω_k} \geq 0.02$ and apparent deviations appear for $\abs{Ω_k} \geq 0.05$. We find that for negatively curved models the apparent deviation is more significant. The manifestation of this apparent deviation from GR due to the assumption of spatial flatness above leads one to conclude that, when using future high-precision data to perform these tests, spatial curvature must be included in the parameter analysis along with the other core cosmological parameters and the MG parameters.

description: Let Gamma be a connected, locally finite graph of finite tree width and G be a group acting on it with finitely many orbits and finite node stabilizers. We provide an elementary and direct construction of a tree T on which G acts with finitely many orbits and finite vertex stabilizers. Moreover, the tree is defined directly in terms of the structure tree of optimally nested cuts of Gamma. Once the tree is constructed, standard Bass-Serre theory yields that G is virtually free. This approach simplifies the existing proofs for the fundamental result of Muller and Schupp that characterizes context-free groups as f.g. virtually free groups. Our construction avoids the explicit use of Stallings' structure theorem and it is self-contained. We also give a simplified proof for an important consequence of the structure tree theory by Dicks and Dunwoody which has been stated by Thomassen and Woess. It says that a f.g. group is accessible if and only if its Cayley graph is accessible.

description: Recently, CMOS has been demonstrated to be a viable technology for very-high-bit-rate broadband and wireless communication systems up to 40 Gb/s and 50 GHz. Advances in device scaling and doping-profile optimization have also resulted n SiGe bipolar transistors with impressive performance, includ-ing cut-off frequencies of more than 200 GHz. This paper presents advances in circuit design which fully exploit the high-speed potential of a 0.13 µm CMOS technology up to 50 GHz and of a high-performance SiGe bipolar technology up to 110 GHz oper-ating frequency. The combination of advanced circuit techniques and a state-of-the-art fabrication-process technology results in continuing the upward shift of the frequency limits.

description: In this paper we examine the validity of the linear perturbation theory near a bounce in the covariant analysis. Some linearity parameters are defined to set up conditions for a linear theory. Linear evolution of density perturbation and gravitational waves have been computed previously. We have calculated the vector and scalar induced parts of the shear tensor. For radiationlike and dustlike single fluid dominated collapsing Friedmann-Lemaitre-Robertson-Walker background it is shown that the linearity conditions are not satisfied near a bounce.

description: The bulk and shear viscosities ($η$ and $ζ$) have been studied for quark-gluon-plasma produced in relativistic heavy ion collisions within semi-classical transport theory, in a recently proposed quasi-particle model of (2+1)-flavor lattice QCD equation of state. These transport parameters have been found to be highly sensitive to the interactions present in hot QCD. Contributions to the transport coefficients from both the gluonic sector and the matter sector have been investigated. The matter sector is found to be significantly dominating over the gluonic sector, in both the cases of $η$ and $ζ$. The temperature dependences of the quantities, $ζ/{\mathcal S}$, and $ζ/η$ indicate a sharply rising trend for the $ζ$, closer to the QCD transition temperature. Both $η$, and $ζ$ are shown to be equally significant for the temperatures that are accessible in the relativistic heavy ion collision experiments, and hence play crucial role while investigating the properties of the quark-gluon plasma.

description: Existing technology cannot adequately address growing needs of submillimeter wave applications. The emerging approaches,such as Quantum Cascade Lasers or terahertz sources using interband transitions operate involve photonics and are limited to cryogenic temperatures.Deep scaled down HEMTs,InP and SiGe HBTs,and even advanced Si MOSFETs are trying to reach the low frequency bound of this range.In this paper,we consider a plasma wave electronics approach for generation and detection of submillimeter wave radiation.This approach that relies on the excitation of electron density haves rather than on the electron drift shows great promise for submillimeter wave applications.

description: Shocks of supernova remnants (SNRs) are important (and perhaps the dominant) agents for production of the Galactic cosmic rays. Recent $γ$-ray observations of several SNRs have made this case more compelling. However, these broadband high-energy measurements also reveal a variety of spectral shape demanding more comprehensive modeling of emissions from SNRs. According to the locally observed fluxes of cosmic ray protons and electrons, the electron-to-proton number ratio is known to be about 1%. Assuming such a ratio is universal for all SNRs and identical spectral shape for all kinds of accelerated particles, we propose a unified model that ascribes the distinct $γ$-ray spectra of different SNRs to variations of the medium density and the spectral difference between cosmic ray electrons and protons observed at Earth to transport effects. For low density environments, the $γ$-ray emission is inverse-Compton dominated. For high density environments like systems of high-energy particles interacting with molecular clouds, the $γ$-ray emission is $π^0$-decay dominated. The model predicts a hadronic origin of $γ$-ray emission from very old remnants interacting mostly with molecular clouds and a leptonic origin for intermediate age remnants whose shocks propagate in a low density environment created by their progenitors via e.g., strong stellar winds. These results can be regarded as evidence in support of the SNR-origin of the Galactic cosmic rays.
