Some Aspects of Rotational and Magnetic Energies for a Hierarchy of Celestial Objects
Creators: name: Sivaram, C.

Publisher: name: arXiv
Year: 2010
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: Celestial objects, from earth like planets to clusters of galaxies, possess angular momentum and magnetic fields. Here we compare the rotational and magnetic energies of a whole range of these celestial objects together with their gravitational self energies and find a number of interesting relationships. The celestial objects, due to their magnetic fields, also posses magnetic moments. The ratio of magnetic moments of these objects with the nuclear magnetic moments also exhibits interesting trends. We also compare their gyromagnetic ratio which appears to fall in a very narrow range for the entire hierarchy of objects. Here we try to understand the physical aspects implied by these observations and the origin of these properties in such a wide range of celestial objects, spanning some twenty orders in mass, magnetic field and other parameters.

An infrared study of D₂O and H₂O inert matrices
Creators: name: Shurvell, Herbert F.
Publisher: name: University of British Columbia
Year: 2011

description: Infrared spectra of and H₂O and D₂O trapped in solid argon, krypton and nitrogen have been obtained at 4°K. In addition, spectra have been recorded of D₂O in carbon tetrachloride and ammonia matrices at 77°K, and of a dilute solution of D₂O in carbon tetrachloride at 25°C. Dilution studies involving changing the matrix to water ratio from 50 to 500 have been carried out with D₂O in argon at 4°K. Changes in the spectra of D₂O and H₂O in argon, krypton and nitrogen matrices during warm-up have been observed. The dilution and warm-up studies have made it possible to assign certain peaks to monomer, low polymer and higher polymers. The complex spectra of H₂O and D₂O in argon, krypton and nitrogen at liquid helium temperatures are discussed, and previous simple explanations involving molecular association, rotation and multiple trapping sites advanced by other workers are shown to be inadequate. Consideration is given to the isotope effect and interactions with the matrix in an attempt to account for the observed spectra.
Extension results for slice regular functions of a quaternionic variable

description: In this paper we prove a new representation formula for slice regular functions, which shows that the value of a slice regular function $f$ at a point $q=x+yI$ can be recovered by the values of $f$ at the points $q+yJ$ and $q+yK$ for any choice of imaginary units $I, J, K.$ This result allows us to extend the known properties of slice regular functions defined on balls centered on the real axis to a much larger class of domains, called axially symmetric domains. We show, in particular, that axially symmetric domains play, for slice regular functions, the role played by domains of holomorphy for holomorphic functions.

The semiclassical continuity equation for open chaotic systems

Publisher: name: arXiv
Year: 2008
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: We consider the continuity equation for open chaotic quantum systems in the semiclassical limit. First we explicitly calculate a semiclassical expansion for the probability current density using an expression based on classical trajectories. The current density is related to the survival probability via the continuity equation, and we show that this relation is satisfied within the semiclassical approximation to all orders. For this we develop recursion relation arguments which connect the trajectory structures involved for the survival probability, which travel from one point in the bulk to another, to those structures involved for the current density, which travel from the bulk to the lead. The current density can also be linked, via another continuity equation, to a correlation function of the scattering matrix whose semiclassical approximation is expressed in terms of trajectories that start and end in the lead. We also show that this continuity equation holds to all orders.

Studies on dissolved molecular oxygen in pure and sea water
Creators: name: Mirhej, Michael Edward
Publisher: name: University of British Columbia
Year: 2011

description: Dissolved oxygen was studied in distilled water and salt solutions by means of nuclear magnetic resonance. The free induction technique was employed to measure the spin lattice relaxation time, T-^, for oxygen-free distilled water and for water containing oxygen under one atmosphere of air and one atmosphere of oxygen at temperatures of 1° to 75°C. The same measurements were made for solutions of 0.5 M sodium chloride at temperatures of 1° to 40°C. The spin lattice relaxation probability, 1/T[subscript 1(c)], in the presence of paramagnetic oxygen, was attributed to two relaxation mechanisms: the first a dipole-dipole interaction and the second a hyperfine interaction. The two terms were evaluated from measurements of T[subscript 1(c)] at two different magnetic field strengths at 20°C. Using the theoretical relationship between the dipole-dipole term and η/T, the results were used to evaluate the hyperfine term at different temperatures. The activation energy obtained from the variation of the dipole-dipole term with temperature was assumed to represent the energy required to break one hydrogen bond between two water molecules. The activation energy found for the hyperfine term was taken as a measure of the breaking of a hydrogen bond between one oxygen molecule and an aggregate of water molecules. The activation energy of the hyperfine term was found to be a function of temperature. Comparison of this quantity with heats of solution of dissolved oxygen in distilled water and salt solution showed a similar pattern of change in both. Oxygen supersaturation was studied in sea water cultures of Nitzschia closterium and Chlorella strain "A" at a temperature of 12°C. Saturation values up to 200% were reached under illumination with light energy of 9.2x10[power -3] langlies/min. Nitzschia was found to be more photosynthetically active, under the same culture conditions, than Chlorella. Oxygen production by Nitzschia was shown to be a function of the difference in photosynthetic pigment concentrations (chlorophyll-a — non-astacin carotenoid), total alkalinity, and the change in catalytic activity of the medium. Variation of oxygen concentration in Nitzschia cultures under light and dark periods indicated a mechanism by which oxygen may escape as microbubbles to the atmosphere. The rate of oxygen desupersaturation was measured in water free of organisms. The rate increased with increase of ion content and with the surface to volume ratio of the water column, but was not influenced by addition of siliceous particulate matter to the supersaturated water. Small addition of a surface active agent (heptanoic acid) increased the oxygen desupersaturation rate but further addition decreased the rate.

description: These lectures aim at providing a pedagogical overview of neutrino physics.
We will mostly deal with standard neutrinos, the ones that are part of the
Standard Model of particle physics, and with their standard dynamics, which is
enough to understand in a coherent picture most of the rich data available.
After introducing the basic theoretical framework, we will illustrate the
experimental determination of the neutrino parameters and their theoretical
implications, in particular for the origin of neutrino masses.

description: This article synthezises the most important results on the kinematics of cuspidal manipulators i.e. nonredundant manipulators that can change posture without meeting a singularity. The characteristic surfaces, the uniqueness domains and the regions of feasible paths in the workspace are defined. Then, several sufficient geometric conditions for a manipulator to be noncuspidal are enumerated and a general necessary and sufficient condition for a manipulator to be cuspidal is provided. An explicit DH-parameter-based condition for an orthogonal manipulator to be cuspidal is derived. The full classification of 3R orthogonal manipulators is provided and all types of cuspidal and noncuspidal orthogonal manipulators are enumerated. Finally, some facts about cuspidal and noncuspidal 6R manipulators are reported.

description: We report the discovery of a T8.5 dwarf, which is a companion to the M4 dwarf Wolf 940. At a distance of 12.50 (+0.75,-0.67) pc, the angular separation of 32arcsec corresponds to a projected separation of 400 AU. The M4 primary displays no Halpha emission, and we apply the age-activity relations of West et al. to place a lower limit on the age of the system of 3.5 Gyr. Weak Halpha absorption suggests some residual activity and we estimate an upper age limit of 6 Gyr. We apply the relations of Bonfils et al for V-Ks and M_Ks to determine the metallicity, [Fe/H] = -0.06 +/- 0.20 for Wolf~940A, and by extension the T8.5 secondary, Wolf 940B. We have obtained JHK NIRI spectroscopy and JHKL' photometry of Wolf 940B, and use these data, in combination with theoretical extensions, to determine its bolometric flux, Fbol = 1.75 +/- 0.18 E-16 Wm^-2 and thus its luminosity log(L*/Lsun) = -6.07 +/- 0.04. Using the age constraints for the system, and evolutionary structural models of Baraffe et al. we determine Teff = 570 +/- 25K and log g = 4.75-5.00 for Wolf940B, based on its bolometric luminosity. This represents the first determination of these properties for a T8+ dwarf that does not rely on the fitting of T-dwarf spectral models. This object represents the first system containing a T8+ dwarf for which fiducial constraints on its properties are available, and we compare its spectra with those of the latest very cool BT-Settl models. This clearly demonstrates that the use of the (W_J,K/J) spectral ratios (used previously to constrain Teff and log g) would have over-estimated Teff by ~100K.

Relativistic space-time positioning: principles and strategies
Creators: name: Tartaglia, Angelo
Publisher: name: INFN Open Access Repository
Year: 2012

description: Starting from the description of space-time as a curved four-dimensional
manifold, null Gaussian coordinates systems as appropriate for relativistic
positioning will be discussed. Different approaches and strategies will be
reviewed, implementing the null coordinates with both continuous and pulsating
electromagnetic signals. In particular, methods based on purely local
measurements of proper time intervals between pulses will be expounded and the
various possible sources of uncertainty will be analyzed. As sources of pulses
both artificial and natural emitters will be considered. The latter will
concentrate on either radio- or X ray-emitting pulsars, discussing advantages
and drawbacks. As for artificial emitters, various solutions will be presented,
from satellites orbiting the Earth to broadcasting devices carried both by
spacecrafts and celestial bodies of the solar system. In general the accuracy
of the positioning is expected to be limited, besides the instabilities and
drift of the sources, by the precision of the local clock, but in any case in
long journeys systematic cumulated errors will tend to become dominant. The
problem can be kept under control properly using a high level of redundancy in
the procedure for the calculation of the coordinates of the receiver and by
mixing a number of different and complementary strategies. Finally various
possibilities for doing fundamental physics experiments by means of space-time
topography techniques will shortly be presented and discussed.

Brane SUSY Breaking and Inflation: Implications for Scalar Fields and
  CMB Distorsion
Creators: name: A. Sagnotti
Publisher: name: INFN Open Access Repository
Year: 2013

description: I elaborate on a link between the string--scale breaking of supersymmetry
that occurs in a class of superstring models and the onset of inflation. The
link rests on spatially flat cosmologies supported by a scalar field driven by
an exponential potential. If, as in String Theory, this potential is steep
enough, under some assumptions that are spelled out in the text the scalar can
only climb up as it emerges from an initial singularity. In the presence of
another mild exponential, slow--roll inflation is thus injected during the
ensuing descent and definite imprints are left in the CMB power spectrum: the
quadrupole is systematically reduced and, depending on the choice of two
parameters, an oscillatory behavior can also emerge for low multipoles l < 50,
in qualitative agreement with WMAP9 and PLANCK data. The experimentally favored
value of the spectral index, n_s ~ 0.96, points to a potentially important role
for the NS fivebrane, which is unstable in this class of models, in the Early
Universe.

description: We have investigated a phase transition of a long-range RKKY Ising spin glass \dyyrusi by means of the dc and the ac magnetization measurements. The static nonlinear susceptibility $χ_{2}$ exhibits a divergent behavior toward $\Tg$ $=$ 1.925 K with the exponent of $γ$ $=$ 1.08. The characteristic relaxation time $τ$ obtained from the ac magnetization measurements also diverges to the same $\Tg$ with the exponent of $zν$ $=$ 1.9 in zero static field . These results indicate the spin glass phase transition belonging to the mean-field universality class, in which the exponents of $\gammaMF$ and $\znuMF$ are 1 and 2 respectively. Moreover, we observed the divergence of $τ$ in a finite field of 500 Oe toward $\Tg$ $=$ 1.412 K with the exponent of $zν$ $=$ 2.1, being quite similar to that in zero field. It strongly suggests an existence of the spin glass phase transition in a finite field and the replica symmetry breaking (RSB) in the long-range Ising spin glass \dyyrusi.

La scoperta del primo segnale diretto di onde gravitazionali non smette di stupire. Un nuovo studio, frutto delle collaborazioni LIGO e Virgo, indica che il segnale di fondo dovuto alla fusione di sistemi binari potrebbe essere circa dieci volte più intenso delle previsioni precedenti.

Optical spin orientation of a single manganese atom in a quantum dot

description: A hight degree of spin polarization is achieved for a Mn atom localized in a semiconductor quantum dot using quasi-resonant optical excitation at zero magnetic field. Optically created spin polarized carriers generate an energy splitting of the Mn spin and enable magnetic moment orientation controlled by the photon helicity and energy. The dynamics and the magnetic field dependence of the optical pumping mechanism shows that the spin lifetime of an isolated Mn atom at zero magnetic field is controlled by a magnetic anisotropy induced by the built-in strain in the quantum dots.
Position Analysis of the RRP-3(SS) Multi-Loop Spatial Structure
Creators: name: Innocenti, Carlo
name: Wenger, Philippe
Publisher: name: arXiv
Year: 2010
Subjects: subject: Robotics (cs.RO)
subject: FOS: Computer and information sciences

description: The paper presents the position analysis of a spatial structure composed of two platforms mutually connected by one RRP and three SS serial kinematic chains, where R, P, and S stand for revolute, prismatic, and spherical kinematic pair respectively. A set of three compatibility equations is laid down that, following algebraic elimination, results in a 28th-order univariate algebraic equation, which in turn provides the addressed problem with 28 solutions in the complex domain. Among the applications of the results presented in this paper is the solution to the forward kinematics of the Tricept, a well-known in-parallel-actuated spatial manipulator. Numerical examples show adoption of the proposed method in dealing with two case studies.
Synthesis and photolysis of aromatic nitrate esters
Creators: name: Csizmadia, Imre Gyula
Publisher: name: University of British Columbia
Year: 2011

description: Nitrate esters of aromatic alcohols were synthesized by esterification which involved competition between 0-nitration and aromatic C-nitration. TLC analysis gave a pattern of adsorption affinities for the nitroxy group and other substituents consistent with the molecular conformations. The NMR frequency of the α-protons showed a linear correlation with the accepted group electronegativities of the substituents in molecules with rigid carbon skeletons and gave a value of 4.18 kcal/mole for the nitroxy group. The symmetric and asymmetric IR stretching frequencies of nitroxy groups in dilute cyclohexane solution were shifted to higher values by steric interaction between contiguous groups when the C-ONO₂ bonds were constrained to coplanarity. The UV spectra showed benzenoid, π→π*, and n→π* bands and a solvent perturbation effect assigned to a solvent → solute charge-transfer interaction. The nitrate esters reacted with the solvent when irradiated in solution in the wavelength range of the n→π* excitation. Product analysis indicated that C-C bond cleavage occurred via intermediate alkoxyl radicals. Rate studies showed the following order of reactivity: benzyl nitrate < dl-hydrobenzoin dinitrate < meso-hydrobenzoin dinitrate, < trans-1, 2-acenaphthenediol nitrate < cis-1, 2-acenaphthenediol dinitrate. The rate measurements and ESR spectra gave evidence of intramolecular energy transfer from the naphthalene moiety to the nitroxy groups in the 1, 2-acenaphthenediol dinitrates assigned as a singlet→singlet transfer. Calculations from the apparent first-order rate constants and spectra showed that benzyl nitrate, and meso- and dl-hydrobenzoin dinitrates photolysed with a quantum yield of about 2 in benzene solution. A solvent effect caused k[subscript Et₂O] > k[subscript EtOH] >k[subscript PhH]. On the basis of product analysis, rate measurements, estimated quantum yields and ESR spectra a mechanism for the nitrate ester photolysis was proposed.

Publisher: name: INFN Open Access Repository
Year: 2015

description: We present the calculation of the non-perturbative renormalization constants
of the energy-momentum tensor in the SU(3) Yang-Mills theory. That computation
is carried out in the framework of shifted boundary conditions, where a thermal
quantum field theory is formulated in a moving reference frame. The
non-perturbative renormalization factors are then used to measure the Equation
of State of the SU(3) Yang-Mills theory. Preliminary numerical results are
presented and discussed.

Ising low-temperature polynomials and hard-sphere gases on cubic

description: We derive and analyze the low-activity and low-density expansions of the
pressure for the model of a hard-sphere gas on cubic lattices of general
dimension $d$, through the 13th order. These calculations are based on our
recent extension to dimension d of the low-temperature expansions for the
specific free-energy of the spin-1/2 Ising models subject to a uniform magnetic
field on the (hyper-)simple-cubic lattices. Estimates of the model parameters
are given also for some other lattices
Probing particle and nuclear physics models of neutrinoless double beta decay with different nuclei

description: Half-life estimates for neutrinoless double beta decay depend on particle physics models for lepton flavor violation, as well as on nuclear physics models for the structure and transitions of candidate nuclei. Different models considered in the literature can be contrasted - via prospective data - with a "standard" scenario characterized by light Majorana neutrino exchange and by the quasiparticle random phase approximation, for which the theoretical covariance matrix has been recently estimated. We show that, assuming future half-life data in four promising nuclei (Ge-76, Se-82, Te-130, and Xe-136), the standard scenario can be distinguished from a few nonstandard physics models, while being compatible with alternative state-of-the-art nuclear calculations (at 95% C.L.). Future signals in different nuclei may thus help to discriminate at least some decay mechanisms, without being spoiled by current nuclear uncertainties. Prospects for possible improvements are also discussed.

A posteriori estimates for Euler and Navier-Stokes equations
Creators: name: Morosi, Carlo
name: Pernici, Mario
name: Pizzocchero, Livio
Publisher: name: AIMS Series on Applied Mathematics 8 (2014), 847-855
Year: 2013

description: The first two sections of this work review the framework of [6] for
approximate solutions of the incompressible Euler or Navier-Stokes (NS)
equations on a torus T^d, in a Sobolev setting. This approach starts from an
approximate solution u_a of the Euler/NS Cauchy problem and, analyzing it a
posteriori, produces estimates on the interval of existence of the exact
solution u and on the distance between u and u_a. The next two sections present
an application to the Euler Cauchy problem, where u_a is a Taylor polynomial in
the time variable t; a special attention is devoted to the case d=3, with an
initial datum for which Behr, Necas and Wu have conjectured a finite time
blowup [1]. These sections combine the general approach of [6] with the
computer algebra methods developed in [9]; choosing the Behr-Necas-Wu datum,
and using for u_a a Taylor polynomial of order 52, a rigorous lower bound is
derived on the interval of existence of the exact solution u, and an estimate
is obtained for the H^3 Sobolev distance between u(t) and u_a(t).

Critical frontier of the Potts and percolation models in triangular-type and kagome-type lattices I: Closed-form expressions
Creators: name: Wu, F. Y.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We consider the Potts model and the related bond, site, and mixed site-bond percolation problems on triangular-type and kagome-type lattices, and derive closed-form expressions for the critical frontier. For triangular-type lattices the critical frontier is known, usually derived from a duality consideration in conjunction with the assumption of a unique transition. Our analysis, however, is rigorous and based on an established result without the need of a uniqueness assumption, thus firmly establishing all derived results. For kagome-type lattices the exact critical frontier is not known. We derive a closed-form expression for the Potts critical frontier by making use of a homogeneity assumption. The closed-form expression is new, and we apply it to a host of problems including site, bond, and mixed site-bond percolation on various lattices. It yields exact thresholds for site percolation on kagome, martini, and other lattices, and is highly accurate numerically in other applications when compared to numerical determination.
