A Stability study of gravity oriented satellites
Creators: name: Brereton, Robert Cloudesley
Publisher: name: University of British Columbia
Year: 2011

description: The stability of gravitational gradient oriented satellites is examined by considering four simplified models. The investigation is carried out numberically and analytically. The techniques employed involve considerable computation and hence are particularly suited to solution by a digital computer. The analysis of the planar motion of a rigid satellite leads to the concept of an invariant surface or integral manifold. Numerical integration of the equation of motion is employed to determine the manifolds. It is shown that for specified values of the parameters describing the satellite, the region in phase space that is consistent with stable motion corresponds to the largest invariant surface which can be found. It is also demonstrated that the manifolds are intimately connected with periodic solutions of the equation of motion and this knowledge permits determining limits on the parameters so as to ensure stable motion by a study of the solution of the variational equation. Several charts suitable for design purposes are presented. The planar motion of a satellite containing a damping mechanism is studied using a simplified model. It is shown that for small dampers the motion eventually becomes nearly identical with a periodic solution of the undamped case. The third model represents a flexible satellite free to deform under the influence of solar heating. An analysis of the temperature distribution in the structure permits determination of the shape of the satellite solely in terms of its position. The resulting equation of motion is derived and it is shown that flexibility does not greatly affect the stability pro- vided that the flexible member is not too long. The case of an axi-symmetric satellite in a circular orbit is also considered. It is shown that in this case manifolds also exist although in some cases apparently ergodic motion can occur. Stability can be guaranteed if the Hamiltonian is less than a prescribed value. Values of the Hamiltonian larger than this may also permit stable motion and in this case an invariant surface is always described in phase space. The stability of the general motion is somewhat greater than that for the planar motion. Charts are presented giving the maximum permissible disturbances for stable motion.

Statistics of first-passage times in disordered systems using backward master equations and their exact renormalization rules

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)

description: We consider the non-equilibrium dynamics of disordered systems as defined by a master equation involving transition rates between configurations (detailed balance is not assumed). To compute the important dynamical time scales in finite-size systems without simulating the actual time evolution which can be extremely slow, we propose to focus on first-passage times that satisfy 'backward master equations'. Upon the iterative elimination of configurations, we obtain the exact renormalization rules that can be followed numerically. To test this approach, we study the statistics of some first-passage times for two disordered models : (i) for the random walk in a two-dimensional self-affine random potential of Hurst exponent $H$, we focus on the first exit time from a square of size $L \times L$ if one starts at the square center. (ii) for the dynamics of the ferromagnetic Sherrington-Kirkpatrick model of $N$ spins, we consider the first passage time $t_f$ to zero-magnetization when starting from a fully magnetized configuration. Besides the expected linear growth of the averaged barrier $\bar{\ln t_{f}} \sim N$, we find that the rescaled distribution of the barrier $(\ln t_{f})$ decays as $e^{- u^η}$ for large $u$ with a tail exponent of order $η\simeq 1.72$. This value can be simply interpreted in terms of rare events if the sample-to-sample fluctuation exponent for the barrier is $ψ_{width}=1/3$.

description: This paper provides a perspective on applying the concepts of information thermodynamics, developed recently in non-equilibrium statistical physics, to problems in theoretical neuroscience. Historically, information and energy in neuroscience have been treated separately, in contrast to physics approaches, where the relationship of entropy production with heat is a central idea. It is argued here that also in neural systems information and energy can be considered within the same theoretical framework. Starting from basic ideas of thermodynamics and information theory on a classic Brownian particle, it is shown how noisy neural networks can infer its probabilistic motion. The decoding of the particle motion by neurons is performed with some accuracy and it has some energy cost, and both can be determined using information thermodynamics. In a similar fashion, we also discuss how neural networks in the brain can learn the particle velocity, and maintain that information in the weights of plastic synapses from a physical point of view. Generally, it is shown how the framework of stochastic and information thermodynamics can be used practically to study neural inference, learning, and information storing.

description: We propose a new low-energy theory for itinerant fermions near a ferromagnetic quantum critical point. We show that the full low-energy model includes, in addition to conventional interaction via spin fluctuations, another type of interaction, whose presence is crucial for the theory to satisfy SU(2) spin conservation. We demonstrate the consistency between a loop-wise expansion and a Fermi liquid description for the full model. We further show that, prior to the ferromagnetic instability, the system develops a Pomeranchuk-type instability into a state with zero magnetization but with p-wave deformations of the Fermi surfaces of spin-up and -down electrons (a spin nematic).

Subjects: subject: Algebraic Geometry (math.AG)

description: This paper contains a proof of a conjecture of Braverman concerning Laumon quasiflag spaces. We consider the generating function Z(m), whose coefficients are the integrals of the equivariant Chern polynomial (with variable m) of the tangent bundles of the Laumon spaces. We prove Braverman's conjecture, which states that Z(m) coincides with the eigenfunction of the Calogero-Sutherland hamiltonian, up to a simple factor which we specify. This conjecture was inspired by the work of Nekrasov in the affine \hat{sl}_n setting, where a similar conjecture is still open.

Generic controllability properties for the bilinear Schrödinger equation

Subjects: subject: Optimization and Control (math.OC)

description: In [15] we proposed a set of sufficient conditions for the approximate controllability of a discrete-spectrum bilinear Schrödinger equation. These conditions are expressed in terms of the controlled potential and of the eigenpairs of the uncontrolled Schrödinger operator. The aim of this paper is to show that these conditions are generic with respect to the uncontrolled and the controlled potential, denoted respectively by $V$ and $W$. More precisely, we prove that the Schrödinger equation is approximately controllable generically with respect to $W$ when $V$ is fixed and also generically with respect to $V$ when $W$ is fixed and non-constant. The results are obtained by analytic perturbation arguments and through the study of asymptotic properties of eigenfunctions.

Expressions for $E_{corr}$ both in the non-relativistic and ultra-relativistic regimes have been derived and compared with the exchange and kinetic term present in the perturbation series. It is observed that the inclusion of correlation energy does not rule out the possibility of the ferromagnetic phase transition at low density within the model proposed by Tatsumi\cite{tatsumi00}. We also derive the spin stiffness constant in the high density limit of such a spin polarized matter.

description: Under two assumptions, we determine the distribution of the difference between two functions each counting the numbers < x that are in a given arithmetic progression modulo q and the product of two primes. The two assumptions are (i) the Extended Riemann Hypothesis for Dirichlet L-functions modulo q, and (ii) that the imaginary parts of the nontrivial zeros of these L-functions are linearly independent over the rationals. Our results are analogs of similar results proved for primes in arithmetic progressions by Rubinstein and Sarnak. In particular, we show that the bias for products of two primes is always reversed from the bias for primes. For example, while Rubinstein and Sarnak showed, under (i) and (ii), that 99.6% of the time there are more primes up to x which are 3 mod 4 than those which are 1 mod 4, we show that 89.4% of the time, there are more products of two primes which are 1 mod 4 than 3 mod 4.

Conductance through a potential barrier embedded in a Luttinger liquid: nonuniversal scaling at strong coupling

description: We calculate the linear response conductance of electrons in a Luttinger liquid with arbitrary interaction g_2, and subject to a potential barrier of arbitrary strength, as a function of temperature. We map the Hamiltonian in the basis of scattering states into an effective low energy Hamiltonian in current algebra form. First the renormalization group (RG) equation for weak interaction is derived in the current operator language both using the operator product expansion and the equation of motion method. To access the strong coupling regime, two methods of deducing the RG equation from perturbation theory, based on the scaling hypothesis and on the Callan-Symanzik formulation, are discussed. The important role of scale independent terms is emphasized. The latter depend on the regulaization scheme used (length versus temperature cutoff). Analyzing the perturbation theory in the fermionic representation, the diagrams contributing to the renormalization group beta-function are identified. A universal part of the beta-function is given by a ladder series and summed to all orders in g_2. First non-universal corrections beyond the ladder series are discussed and are shown to differ from the exact solutions obtained within conformal field theory which use a different regularization scheme. The RG equation for the temperature dependent conductance is solved analytically. Our result agrees with known limiting cases.

Von Neumann and Luders postulates and quantum information theory

description: This note is devoted to some foundational aspects of quantum mechanics (QM) related to quantum information (QI) theory, especially quantum teleportation and ``one way quantum computing.'' We emphasize the role of the projection postulate (determining post-measurement states) in QI and the difference between its Lüders and von Neumann versions. These projection postulates differ crucially in the case of observables with degenerate spectra. Such observables play the fundamental role in operations with entangled states: any measurement on one subsystem is represented by an observable with degenerate spectrum in the Hilbert space of a composite system. If von Neumann was right and Lüders was wrong the canonical schemes of quantum teleportation and ``one way quantum computing'' would not work. Surprisingly, we found that, in fact, von Neumann's description of measurements via refinement implies (under natural assumptions) Lüders projection postulate. It seems that this important observation was missed during last 70 years. This result closed the problem of the proper use of the projection postulate in quantum information theory. One can proceed with Lüders postulate (as people in quantum information really do).
What Determines Size Distributions of Heavy Drops in a Synthetic Turbulent Flow?

Year: 2009
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We present results from an individual particle based model for the collision, coagulation and fragmentation of heavy drops moving in a turbulent flow. Such a model framework can help to bridge the gap between the full hydrodynamic simulation of two phase flows, which can usually only study few particles and mean field based approaches for coagulation and fragmentation relying heavily on parameterization and are for example unable to fully capture particle inertia. We study the steady state that results from a balance between coagulation and fragmentation and the impact of particle properties and flow properties on this steady state. We compare two different fragmentation mechanisms, size-limiting fragmentation where particles fragment when exceeding a maximum size and shear fragmentation, where particles break up when local shear forces in the flow exceed the binding force of the particle. For size-limiting fragmentation the steady state is mainly influenced by the maximum stable particle size, while particle and flow properties only influence the approach to the steady state. For shear fragmentation both the approach to the steady state and the steady state itself depend on the particle and flow parameters. There we find scaling relationships between the steady state and the particle and flow parameters that are determined by the stability condition for fragmentation.

Collision Thermalization of Nucleons in Relativistic Heavy-Ion Collisions

description: We consider a possible mechanism of thermalization of nucleons in relativistic heavy-ion collisions. Our model belongs, to a certain degree, to the transport ones; we investigate the evolution of the system created in nucleus-nucleus collision, but we parametrize this development by the number of collisions of every particle during evolution rather than by the time variable. We based on the assumption that the nucleon momentum transfer after several nucleon-nucleon (-hadron) elastic and inelastic collisions becomes a random quantity driven by a proper distribution. This randomization results in a smearing of the nucleon momenta about their initial values and, as a consequence, in their partial isotropization and thermalization. The trial evaluation is made in the framework of a toy model. We show that the proposed scheme can be used for extraction of the physical information from experimental data on nucleon rapidity distribution.

description: We use a Feshbach resonance to tune the scattering length a of a Bose-Einstein condensate of 7Li in the |F = 1, m_F = 1> state. Using the spatial extent of the trapped condensate we extract a over a range spanning 7 decades from small attractive interactions to extremely strong repulsive interactions. The shallow zero-crossing in the wing of the Feshbach resonance enables the determination of a as small as 0.01 Bohr radii. In this regime, evidence of the weak anisotropic magnetic dipole interaction is obtained by comparison with different trap geometries.
Studies of feeding activities of cope-pods in Marion Lake, B.C.
Creators: name: McQueen, Donald James
Publisher: name: University of British Columbia
Year: 2011

description: The standing crop of the copepod G. b. thomasi Forbes in Marion Lake, B. C, has been recorded during 1966 and 1967. These copepods excysted as stage IV copepodids during April and moulted to adults, which produced eggs in May. The new population developed to the copepodid IV stage by mid-summer, when 85 % of the animals returned to the bottom and encysted. The copepodids of stage IV and V and the adults are predators. In the laboratory, six groups of animals were presented separately to the predator, which preyed most efficiently on cyclopoid nauplii and copepodids, diaptomid nauplii and rotifers; and least efficiently on diaptomid copepodids and cladocera. In the lake, the forms least affected by cyclopoid predation were also the diaptomid copepodids and cladocera. There was a correlation between C. b. thomasi encystment and food shortage, which suggests that food shortage may stimulate encystment of stage IV copepodids.

Cryogenic developments towards the Einstein Telescope (ET)
Creators: name: Grohmann, Steffen

Year: 2021

description: The Einstein Telescope (ET) is a 3rd generation gravitational-wave detector planned in triangular shape with 10 km arm lengths in an underground installation at a depth of 200 m to 300 m. While 2nd generation detectors and the ET high-frequency interferometer are operated at room-temperature, the ET low-frequency (LF) interferometer shall be operated at cryogenic mirror temperatures of 10 K to 20 K, extending the frequency range of ET down to 3 Hz and opening a new window to precision astronomy. The cryogenic operation is required to reduce the Brownian motion of atoms in the mirrors and suspensions that limits the achievable sensitivity. The mirror cooling, however, needs to be performed in an ultra-quiet manner in order to ensure a mirror stability on the level of $1\times10^{-20}\,\mathrm{m/\sqrt{Hz}}$. Beside the challenging mirror cooling, cryogenic developments are required for cryopumping in the cryostats, in particular for the mitigation and the regeneration of frost formation on the mirror surfaces, and for the cooling of large cryo-traps between the 10 km arm pipe ends and the cryostats. Starting with an overview on the ET objectives, design and project schedule, this talk summarises the cryogenic requirements of this large-scale future experiment. Present developments for the ET-LF mirror cooling and the cryo-vacuum technology are being presented.

description: The subjects of this paper are the Kingdom of Tonga,1 its monarchy, its constitution, its traditional values and political reform. It is now well known that the government and Legislative Assembly of Tonga (the Assembly) made a momentous decision four years ago in 2010, when it amended the Constitution of Tonga (the Constitution) to shift most of the executive powers of the state from the monarch to a cabinet of elected leaders. For the firsttime in Tonga’s history, the government was then elected. Four years later, on 27 November 2014, that government was called to account when Tongans went to the polls again to elect a second one.

description: We consider the recent limits on dark matter - nucleon elastic scattering cross section from the analysis of CDMS II collaboration using the two signal events observed in CDMS experiment. With these limits we try to interpret the Super-Kamiokande (SK) bounds on the detection rates of up-going muons induced by the neutrinos that are produced in the sun from the decay of annihilation products of dark matter (WIMPs) captured in the solar core. Calculated rates of up-going muons for different annihilation channels at SK using CDMS bounds are found to be orders below the predicted upper limits of such up-going muon rates at SK. Thus there exists room for enhancement (boost) of the calculated rates using CDMS limits for interpreting SK bounds. Such a feature is expected to represent the PAMELA data with the current CDMS limits. We also show the dependence of such a possible enhancement factor (boost) on WIMP mass for different WIMP annihilation channels.

description: Two generations of a novel detector for high-resolution transmission imaging and spectrometry of fast-neutrons are presented. These devices are based on a hydrogenous fiber scintillator screen and single- or multiple-gated intensified camera systems (ICCD). This detector is designed for energy-selective neutron radiography with nanosecond-pulsed broad-energy (1 - 10 MeV) neutron beams. Utilizing the Time-of-Flight (TOF) method, such a detector is capable of simultaneously capturing several images, each at a different neutron energy (TOF). In addition, a gamma-ray image can also be simultaneously registered, allowing combined neutron/gamma inspection of objects. This permits combining the sensitivity of the fast-neutron resonance method to low-Z elements with that of gamma radiography to high-Z materials.

description: Oxidative stress has impacts on the KRas and Nrf2/Keap1 pathways, which have multiple interactions with each other and play important roles in colorectal cancer (CRC). This study investigated the expressions of proteins in the KRas and Nrf2/Keap1 pathways and their associations with clinicopathological features in CRC. The protein levels of Nrf2, Keap1, Bach1, p62, HO1, KRas, Erk, Raf1 and PI3K in both the tumour and normal tissues of 60 CRC subjects were determined by Western blot and their T/N (tumour/normal tissue) ratios were correlated with clinicopathological features. The T/N ratios of proteins in the KRas and Nrf2/Keap1 pathways had correlation patterns and proximity profiles in cluster dendrograms different in CRC with different status of lymphovascular invasion (LVI) or lymph node/distant metastases. The Keap1 protein T/N ratio was a significant predictor (odd ratio: 2.24; 95% confidence interval: 1.26 − 4.38) of LVI, which in turn predicted metastases (11.0; 3.49 − 39.8). The interactions between the KRas and Nrf2/Keap1 pathways may be affected differently by LVI and metastases, and the protein T/N ratio of Keap1 may be helpful for predicting LVI in CRC.
Measure for the Degree of Non-Markovian Behavior of Quantum Processes in Open Systems

description: We construct a general measure for the degree of non-Markovian behavior in open quantum systems. This measure is based on the trace distance which quantifies the distinguishability of quantum states. It represents a functional of the dynamical map describing the time evolution of physical states, and can be interpreted in terms of the information flow between the open system and its environment. The measure takes on nonzero values whenever there is a flow of information from the environment back to the open system, which is the key feature of non-Markovian dynamics.

description: We study how the resonant decay of moduli fields arising in the Minimal Supersymmetric Standard Model (MSSM) could affect large scale curvature perturbations in the early universe. It has been known for some time that the presence of entropy perturbations in a multi-component system can act as seeds for the curvature perturbations on all scales. These entropy perturbations could be amplified exponentially if one of the moduli decays via stochastic resonance, affecting the curvature power spectrum in the process. By imposing the COBE normalization on this power spectrum, one could put constraints on the masses and couplings of the underlying particle physics model without having to rely on collider experiments. We discuss in detail the case of the MSSM but this method could be applied to other theories beyond the Standard Model.

From Margins to Mainstream: A Longitudinal Analysis of Women's Empowerment in Pakistan and the Role of International Tourism
Creators: name: Rehman, Wasi Ur

Publisher: name: Zenodo
Year: 2023

description: The primary objective of this study is to investigate the impact of international tourism, female literacy, female participation rate, gender disparity in health, women's access to finance, and economic growth on women's empowerment in Pakistan. The analysis isconducted using data from the period spanning 1975 to 2020. The findings of the study reveal that international tourism plays a significant role in promoting women's empowerment. However, gender disparity in health, education, access to finance, andeconomic growth hinders women's empowerment in the country. Consequently, it is crucial for the government to focus on reducing gender disparities in health to empower women effectively. Furthermore, the government should create more opportunities for women to participate in the financial market, as this can contribute to improving their livelihoods. Efforts should be made to attract more foreign visitors to the country, as this can generate additional revenue and foster women's empowerment, particularly in tourist destinations.
Reproductive physiology of the viviparous sea perch, Cymatogaster aggregata Gibbons
Creators: name: Wiebe, John P.
Publisher: name: University of British Columbia
Year: 2011

description: The natural cycle of reproduction in Cymatogaster aggregata Gibbons, a viviparous teleost, has been described and investigated experimentally. Laboratory manipulations of photo-period and temperature show that both are concerned with the environmental regulation of the cycle. The role of the pituitary was studied by the use of Methallibure, a chemical inhibitor of pituitary gonadotropic function. 3β— and 17β- hydroxysteroid dehydrogenases were localized in the gonads by histochemical tests and testicular steroids were partly identified biochemically. The role of androgens was studied with gonadectomized specimens and steroid replacement therapy. These various techniques indicate that increasing daylength in March and April stimulates production and/or release of pituitary gonadotropins and that the gonadotropins in turn initiate spermatogenesis and stimulate interstitial Leydig cells. The warm temperature of intertidal waters in addition to the long period of daily illumination from May to July accelerate spermatogenesis and testicular steroidogenesis. Increased gonadal androgen production, in turn, results in a modification of the male anal fin and brings on a full display of reproductive behaviour; some of the behaviour sequence, however, is controlled by pituitary gonadotropins. Restitution of the testes occurs in fall and winter. Oocyte formation appears to be enhanced by a lowered titre of gonadotropic hormones resulting from the warm temperatures of July and August. On the other hand, oocyte maturation in late autumn and early winter and gestation during early pregnancy require pituitary gonadotropins.
Magnetization reversal in amorphous Fe/Dy multilayers: a Monte Carlo study

description: The Monte Carlo method in the canonical ensemble is used to investigate magnetization reversal in amorphous transition metal - rare earth multilayers. Our study is based on a model containing diluted clusters which exhibit an effective uniaxial anisotropy in competition with random magnetic anisotropy in the matrix. We simulate hysteresis loops for an abrupt profile and a diffuse one obtained from atom probe tomography analyses. Our results evidence that the atom probe tomography profile favors perpendicular magnetic anisotropy in agreement with magnetic measurements. Moreover, the hysteresis loops calculated at several temperatures qualitatively agree with the experimental ones.
Monopole operators in N=4 Chern-Simons theories and wrapped M2-branes

description: Monopole operators in Abelian N=4 Chern-Simons theories described by circular quiver diagrams are investigated. The magnetic charges of non-diagonal U(1) gauge symmetries form the SU(p)xSU(q) root lattice where p and q are numbers of untwisted and twisted hypermultiplets, respectively. For monopole operators corresponding to the root vectors, we propose a correspondence between the monopole operators and states of a wrapped M2-brane in the dual geometry.
