Exact solutions in the FPU oscillator chain
Creators: name: P. Poggi

Publisher: name: INFN Open Access Repository
Year: 1995

description: After a brief comprehensive review of old and new results on the well known
Fermi-Pasta-Ulam (FPU) conservative system of $N$ nonlinearly coupled
oscillators, we present a compact linear mode representation of the Hamiltonian
of the FPU system with quartic nonlinearity and periodic boundary conditions,
with explicitly computed mode coupling coefficients. The core of the paper is
the proof of the existence of one-mode and two-mode exact solutions, physically
representing nonlinear standing and travelling waves of small wavelength whose
explicit lattice representations are obtained, and which are valid also as $N
\rightarrow \infty$. Moreover, and more generally, we show the presence of
multi-mode invariant submanifolds. Destabilization of these solutions by a
parametric perturbation mechanism leads to the establishment of chaotic in time
mode interaction channels, corresponding to the formation in phase space of
bounded stochastic layers on submanifolds. The full mode-space stability
problem of the $N/2$ zone-boundary mode is solved, showing that this mode
becomes unstable through a mechanism of the modulational Benjamin-Feir type. In
the thermodynamic limit the mode is always unstable but with instability growth
rate linearly vanishing with energy density. The physical significance of these
solutions and of their stability properties, with respect to the previously
much more studied equipartition problem for long wavelength initial
excitations, is briefly discussed.

Dirac's Observables for the Rest-Frame Instant Form of Tetrad Gravity in
  a Completely Fixed 3-Orthogonal Gauge

Year: 2001

description: We define the {\it rest-frame instant form} of tetrad gravity restricted to
Christodoulou-Klainermann spacetimes. After a study of the Hamiltonian group of
gauge transformations generated by the 14 first class constraints of the
theory, we define and solve the multitemporal equations associated with the
rotation and space diffeomorphism constraints, finding how the cotriads and
their momenta depend on the corresponding gauge variables. This allows to find
quasi-Shanmugadhasan canonical transformation to the class of 3-orthogonal
gauges and to find the Dirac observables for superspace in these gauges.
  The construction of the explicit form of the transformation and of the
solution of the rotation and supermomentum constraints is reduced to solve a
system of elliptic linear and quasi-linear partial differential equations. We
then show that the superhamiltonian constraint becomes the Lichnerowicz
equation for the conformal factor of the 3-metric and that the last gauge
variable is the momentum conjugated to the conformal factor. The gauge
transformations generated by the superhamiltonian constraint perform the
transitions among the allowed foliations of spacetime, so that the theory is
independent from its 3+1 splittings. In the special 3-orthogonal gauge defined
by the vanishing of the conformal factor momentum we determine the final Dirac
observables for the gravitational field even if we are not able to solve the
Lichnerowicz equation. The final Hamiltonian is the weak ADM energy restricted
to this completely fixed gauge.
A real-time analogue computer for the estimation of system dynamics
Creators: name: Parker, Lloyd Edward George,
Publisher: name: University of British Columbia
Year: 2012

description: It is possible to obtain, the best (in the minimum mean-square error sense) linear model of a control system by solving a convolution-type integral for the impulse response of the system. This thesis presents a method for obtaining an approximate solution for the impulse response by solving a system of linear equations which is statistically equivalent to the convolution integral. An analogue computer which can solve the system of equations is described. The computer samples the sign of the input signal at an adjustable rate and stores this information in a shift register. The output signals from the shift register are then used to compute functions statistically related to the correlation functions of the system signals. A set of linear equations relating these functions is solved using an arrangement similar to the Gauss-Seidel Iteration method. The computer utilizes a time-sharing technique and the step response of the system can be generated as a repetitive waveform. The overall operation of the computer is described in block diagram form. The individual circuits are described and the results of a computational test are given.

Exact height distributions for the KPZ equation with narrow wedge initial condition

description: We consider the KPZ equation in one space dimension with narrow wedge initial condition, $h(x,t=0)=- |x|/δ$, $δ\ll 1$. Based on previous results for the weakly asymmetric simple exclusion process with step initial conditions, we obtain a determinantal formula for the one-point distribution of the solution $h(x,t)$ valid for any $x$ and $t>0$. The corresponding distribution function converges in the long time limit, $t\to\infty$, to the Tracy-Widom distribution. The first order correction is a shift of order $t^{-1/3}$. We provide numerical computations based on the exact formula.

description: Three different tire/road coefficient of friction measuring methods are investigated and compared for their use in the field of vehicular accident reconstruction. Locked-wheel skid tests, considered to be the most accurate method, were performed with an instrumented test vehicle to establish base values that could be compared to values measured using a tow cable method and a portable drag sled method. A set of high performance radial tires and a set of standard production radial tires were each tested on two different surfaces to broaden the range of friction values measured. In a series of tow cable tests, the test vehicle was pulled, with wheels locked, over each surface at low speeds. The tow cable coefficient of friction decreased with increasing sliding speed. Portable drag sleds were constructed from a tire in each tire set. Weights were added to each drag sled to study the effect of increasing load on the coefficient of friction. Tests were performed with drag sleds weighing 26 pounds, 51 pounds, and 76 pounds. The drag sled coefficient of friction was independent of sliding speed. The investigation showed a correlation did not exist between the coefficient of friction values determined by the drag sled and tow cable methods when compared to the values determined by the locked-wheel skid test method. Depending on the tire/surface combination tested, the tow cable tests overestimated the skid test coefficient of friction by 28 to 81.4 percent. Similarly, the drag sleds overestimated the skid test coefficient of friction by 31.4 percent to as much as 114.5 percent

description: The purpose of this paper is to extend the Green-Naghdi-Rivlin balance of energy method to continua with microstructure. The key idea is to replace the group of Galilean transformations with the group of diffeomorphisms of the ambient space. A key advantage is that one obtains in a natural way all the needed balance laws on both the macro and micro levels along with two Doyle-Erickson formulas.

Year: 2003

description: This is part I of a two-part review of charm physics.
  After briefly recapitulating the history of the charm quantum number we
sketch the experimental environments and instruments employed to study the
behaviour of charm hadrons and then describe the theoretical tools for treating
charm dynamics. After discussing a wide range of inclusive production processes
we analyze the spectroscopy of hadrons with hidden and open charm and the weak
lifetimes of charm mesons and baryons.
  In part II we shall address exclusive charm decays, $D^0 - \bar D^0$
oscillations and CP violation.
  This review is meant to be both a pedagogical introduction for the young
scholar and a useful reference for the experienced researcher. We aim for a
complete description of the fundamental features while providing a guide
through the literature for purely technical issues.

description: Bioavailable nitrogen is thought to be a requirement for the origin and sustenance of life. Before the onset of biological nitrogen fixation, abiotic pathways to fix atmospheric N2 must have been prominent to provide bioavailable nitrogen to Earth's earliest ecosystems. Lightning has been shown to produce fixed nitrogen as nitrite and nitrate in both modern atmospheres dominated by N2 and O2 and atmospheres dominated by N2 and CO2 analogous to the Archaean Earth. However, a better understanding of the isotopic fingerprints of lightning-generated fixed nitrogen is needed to assess the role of this process on the early Earth. Here, we present results from spark discharge experiments in N2-CO2 and N2-O2 gas mixtures. Our experiments suggest that lightning-driven nitrogen fixation may have been similarly efficient in the Archaean atmosphere, compared to modern times. Measurements of the isotopic ratio δ15N of the discharge-produced nitrite and nitrate in solution show very low values of -6 to -15 permil after equilibration with the gas phase with a calculated endmember composition of -17 permil. These results are much lower than most δ15N values documented from the sedimentary rock record, which supports the development of biological nitrogen fixation earlier than 3.2 Ga. However, some Paleoarchean records (3.7 Ga) may be consistent with lightning-derived nitrogen input, highlighting the potential role of this process for the earliest ecosystems.

Optimizing end-labeled free-solution electrophoresis by increasing the hydrodynamic friction of the drag-tag

description: We study the electrophoretic separation of polyelectrolytes of varying lengths by means of end-labeled free-solution electrophoresis (ELFSE). A coarse-grained molecular dynamics simulation model, using full electrostatic interactions and a mesoscopic Lattice Boltzmann fluid to account for hydrodynamic interactions, is used to characterize the drag coefficients of different label types: linear and branched polymeric labels, as well as transiently bound micelles. It is specifically shown that the label's drag coefficient is determined by its hydrodynamic size, and that the drag per label monomer is largest for linear labels. However, the addition of side chains to a linear label offers the possibility to increase the hydrodynamic size, and therefore the label efficiency, without having to increase the linear length of the label, thereby simplifying synthesis. The third class of labels investigated, transiently bound micelles, seems very promising for the usage in ELFSE, as they provide a significant higher hydrodynamic drag than the other label types. The results are compared to theoretical predictions, and we investigate how the efficiency of the ELFSE method can be improved by using smartly designed drag-tags.

description: We study the correlators of a recently discovered family of BPS Wilson loops in ${\cal N}=4$ supersymmetric U(N) Yang-Mills theory. When the contours lie on a two-sphere in the space-time, we propose a closed expression that is valid for all values of the coupling constant $g$ and for any rank $N$, by exploiting the suspected relation with two-dimensional gauge theories. We check this formula perturbatively at order ${\cal O}(g^4)$ for two latitude Wilson loops and we show that, in the limit where one of the loops shrinks to a point, logarithmic corrections in the shrinking radius are absent at ${\cal O}(g^6)$. This last result strongly supports the validity of our general expression and suggests the existence of a peculiar protected local operator arising in the OPE of the Wilson loop. At strong coupling we compare our result to the string dual of the ${\cal N}=4$ SYM correlator in the limit of large separation, presenting some preliminary evidence for the agreement.

Accurate Fundamental Stellar Parameters

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We combine results from interferometry, asteroseismology and spectroscopic analyses to determine accurate fundamental parameters (mass, radius and effective temperature) of 10 bright solar-type stars covering the H-R diagram from spectral type F5 to K1. Using ``direct'' techniques that are only weakly model-dependent we determine the mass, radius and effective temperature. We demonstrate that model-dependent or ``indirect'' methods can be reliably used even for relatively faint single stars for which direct methods are not applicable. This is important for the characterization of the targets of the CoRoT and Kepler space missions.

description: The aim of this paper is to present an adaptable Fat Tree NoC architecture for Field Programmable Gate Array (FPGA) designed for image analysis applications. Traditional NoCs (Network on Chip) are not optimal for dataflow applications with large amount of data. On the opposite, point to point communications are designed from the algorithm requirements but they are expensives in terms of resource and wire. We propose a dedicated communication architecture for image analysis algorithms. This communication mechanism is a generic NoC infrastructure dedicated to dataflow image processing applications, mixing circuit-switching and packet-switching communications. The complete architecture integrates two dedicated communication architectures and reusable IP blocks. Communications are based on the NoC concept to support the high bandwidth required for a large number and type of data.
Intrinsic Coupling between Current and Domain Wall Motion in (Ga,Mn)As

description: We consider current-induced domain wall motion and, the reciprocal process, moving domain wall-induced current. The associated Onsager coefficients are expressed in terms of scattering matrices. Uncommonly, in (Ga,Mn)As, the effective Gilbert damping coefficient $α_w$ and the effective out-of-plane spin transfer torque parameter $β_w$ are dominated by spin-orbit interaction in combination with scattering off the domain wall, and not scattering off extrinsic impurities. Numerical calculations give $α_w \sim 0.01$ and $β_w \sim 1$ in dirty (Ga,Mn)As. The extraordinary large $β_w$ parameter allows experimental detection of current or voltage induced by domain wall motion in (Ga,Mn)As.

description: Using in-field single crystal neutron diffraction we have determined the magnetic structure of TbMnO3 in the high field P||a phase. We unambiguously establish that the ferroelectric polarization arises from a cycloidal Mn spins ordering, with spins rotating in the ab plane. Our results demonstrate directly that the flop of the ferroelectric polarization in TbMnO3 with applied magnetic field is caused from the flop of the Mn cycloidal plane.

description: We present a calculation of the N to $Δ$ electromagnetic transition amplitudes using the method of QCD sum rules. A complete set of QCD sum rules are derived for the entire family of transitions from the baryon octet to decuplet. They are analyzed in conjunction with the corresponding mass sum rules using a Monte-Carlo-based analysis procedure. The performance of each of the sum rules is examined using the criteria of OPE convergence and ground-state dominance, along with the role of the transitions in intermediate states. Individual contributions from the u, d and s quarks are isolated and their implications in the underlying dynamics are explored. Valid sum rules are identified and their predictions are obtained. The results are compared with experiment and other calculations.

description: We have investigated the pulse shape evolution of the Crab pulsar emission in the hard X-ray domain of the electromagnetic spectrum. In particular, we have studied the alignment of the Crab pulsar phase profiles measured in the hard X-rays and in other wavebands. To obtain the hard X-ray pulse profiles, we have used six year (2003-2009, with a total exposure of about 4 Ms) of publicly available data of the SPI telescope on-board of the INTEGRAL observatory, folded with the pulsar time solution derived from the Jodrell Bank Crab Pulsar Monthly Ephemeris. We found that the main pulse in the hard X-ray 20-100 keV energy band is leading the radio one by $8.18\pm0.46$ milliperiods in phase, or $275\pm15 μs$ in time. Quoted errors represent only statistical uncertainties.Our systematic error is estimated to be $\sim 40 μs$ and is mainly caused by the radio measurement uncertainties. In hard X-rays, the average distance between the main pulse and interpulse on the phase plane is $0.3989\pm0.0009$. To compare our findings in hard X-rays with the soft 2-20 keV X-ray band, we have used data of quasi-simultaneous Crab observations with the PCA monitor on-board the Rossi X-Ray Timing Explorer (RXTE) mission. The time lag and the pulses separation values measured in the 3-20 keV band are $0.00933\pm0.00016$ (corresponding to $310\pm6 μs$) and $0.40016\pm0.00028$ parts of the cycle, respectively. While the pulse separation values measured in soft X-rays and hard X-rays agree, the time lags are statistically different. Additional analysis show that the delay between the radio and X-ray signals varies with energy in the 2 - 300 keV energy range. We explain such a behaviour as due to the superposition of two independent components responsible for the Crab pulsed emission in this energy band.

description: Traditional hexavalent hard chrome coatings produced from chromium trioxide are providing reasonable corrosion and wear resistance, which recognised as a carcinogen and its use controlled by reach legislation. Many researchers have investigated as the ability of Mo and W to codeposit with iron group metals (Ni, Fe, Co) to form crystalline and amorphous compounds and more recently, work has shown that nano-crystalline coatings may be produced with high hardness.In this thesis, Co-W electrodeposited coatings are investigated structurally, compositionally, and morphologically. Series of Co-W alloy coatings with variable structures and composition were obtained using a gluconate bath and a soluble Co anode at 80 °C temperature and 2.7 Adm-2 current density with air agitation.Some of these samples at the same compositions illustrate at different preferred growth directions of (100), (101), (002) and (110) and these differences occur due to variations in agitation. SEM/EDX and XRD and microhardness were employed to characterise the coatings and how they differ across the samples due to edge effects. Variation in W content of 2 – 3 at.% changes in W content of the coatings affect the hardness significantly up to around 50%.Coatings were selected for heat treatment process based on composition and preferred orientation. The effect on the structure and hardness of the coatings after heat treatment at 600 °C for the duration up to 160 hours was explored using XRD and SEM. Two of 20 at.% W electrodeposited coatings at (100) and (101) preferred growth direction examined on TEM as electrodeposited and after 2 hours heat treatment by sample preparations of ion beam vertically and horizontally to the coating in the cross section using nanotechnological developments. The wear behaviour some of these samples examined under dry sliding conditions.

Iterative synthesis of a flat-staggered emitter-feedback transistor video amplifier
Creators: name: Cameron, Frank Charles
Publisher: name: University of British Columbia
Year: 2011

description: Bruun and Grinich have previously described video amplifier designs using resistance-capacitance feedback in the emitter lead for stages in the common-emitter configuration. Diffusion-type alloy-junction transistors which are well described by the Johnson-Giacoletto hybrid-π equivalent circuit, were used in both cases. The amplifier cascades described by Grinich produced Butterworth-type responses through use of pole-zero cancellation. The research reported here is concerned with an alternative design method using an iterative numerical procedure to obtain broadband amplifier cascades without the use of pole-zero cancellation. In addition, the method is sufficiently general to include both drift- and diffusion-type alloy-junction transistors. Equivalent circuits of the Johnson-Giacoletto hybrid-π type are reviewed and modifications necessary to treat emitter feedback amplifiers using the newer types of high-frequency transistors are developed. Transfer functions for stages and cascades of stages using either drift- or diffusion-types of transistors in the common-emitter configuration with emitter feedback are given. Special attention is given to the property of this type of amplifier that the zeros and poles of the transfer function are interdependent. Suitable parameters for defining this dependence are developed, and the problem of synthesizing for flat amplitude response, in spite of this dependence, is described. A numerical iterative method of solution is proposed. A numerical example of a three-stage amplifier design using a 2N384 p-n-p drift transistor for maximally-flat amplitude response with a passband from 40 cps to 6.5 Mc is given. The design is compared with an equivalent amplifier of the Butter-worth type obtained by the Grinich method. It is shown that an optimum interstage resistance giving maximum dc amplification exists when using this iterative method, but that there is no true optimum for Grinich designs. The theoretical designs obtained by the iterative method give an amplification of 49.6 db, 7.6 db greater than by the Grinich method for the particular value of interstage resistance used (300Ω). Phase linearity, delay, and step-response overshoot are comparable for the two designs. The numerical method shows good convergence properties, except when designing for very small or very large bandwidths, or for very small dc emitter currents or interstage resistances. An amplifier built according to the theoretical design, but fitted with an input impedance-matching pad and an output emitter-follower pair for connection to a 50-Ω line, is described. Test results indicate that the design values obtained using the modified Johnson-Giacoletto hybrid-π equivalent circuit and the iterative method are sufficiently accurate for construction purposes and that very little adjustment is necessary. Suggestions for further development of the method are given.

description: This study investigated the in vitro dissolution and in vivo absorption of rifampicin (RIF)-containing 3D-printed tablets using Selective Laser Sintering (SLS) technology. In vitro dissolution was assessed in acidic (pH 1.2) and alkaline (pH 6.8) buffer media, while in vivo absorption was evaluated in a New Zealand White rabbit model. Both analytical and bioanalytical methods were rigorously developed and validated using LC-ESI-MS/MS, following ICH Q2 (R1) and FDA guidelines, respectively. In the acidic medium, 16.22% of RIF was released within the first 2 h, whereas in the alkaline medium, the release increased to 41.75%, indicating a sustained release from the sintered 3D printed tablets. Pharmacokinetic parameters and their corresponding values of Cmax (445.38 ± 193.62 ng/mL), Tmax (02 ± 0.00 hr), AUC0-t (841.51 ± 334.13 ng.h/mL), AUC0-∞ (861.66 ± 340.54 ng.h/mL), Kel (0.61 ± 0.13 h−1), and t1/2 (1.18 ± 0.25 hr) were obtained, demonstrating effective RIF absorption in the rabbit. Additionally, an in vitro-in vivo correlation (IVIVC) model was developed, demonstrating a good correlation between in vitro release and in vivo absorption, with R2 value of 0.9696. The results underscore the potential of SLS 3DP technology in advancing the development of RIF-containing 3D printed tablets by sustaining in vitro dissolution following in vivo absorption profiles.
