Effectiveness of individualized ressource-oriented joint protection education in people with rheumatoid arthritis : a randomized controlled trial

Objective
The modern joint protection (JP) concept for people with rheumatoid arthritis (RA) is an active coping strategy to improve daily tasks and role performance by changing working methods and using assistive devices. Effective group JP education includes psycho-educational interventions. The Pictorial Representation of Illness and Self Measure (PRISM) is an interactive hands-on-tool, assessing (a) the individual's perceived burden of illness and (b) relevant individual resources. Both issues are important for intrinsic motivation to take action and change behaviour. This study compared individual conventional JP education (C-JP) with PRISM-based JP education (PRISM-JP).
Methods
An assessor-blinded multicentre randomized controlled trial, including four JP education sessions over 3 weeks, with assessments at baseline and 3 months.
Results
In total 53 RA patients participated. At 3 months, the PRISM-JP (n = 26) participants did significantly better compared to the C-JP participants (n = 27) in JP behaviour (p = 0.02 and p = 0.008 when corrected for baseline values), Arthritis Self-efficacy (ASES, p = 0.015) and JP self-efficacy (JP-SES, p = 0.047). Within-group analysis also showed less hand pain (p < 0.001) in PRISM-JP group.
Conclusion
PRISM-JP more effectively supported learning of JP methods, with meaningful occupations, resource activation and self-efficacy acting as important mediators.
Practice implications
PRISM improved patient–clinician communication and is feasible for occupational therapy
Tunnel magnetoresistance in GaMnAs: going beyond Jullière formula

The relation between tunnel magnetoresistance (TMR) and spin polarization is explored for GaMnAs∕GaAlAs∕GaMnAs structures where the carriers experience strong spin–orbit interactions. TMR is calculated using the Landauer approach. The materials are described in the 6 band k⋅p model which includes spin–orbit interaction. Ferromagnetism is described in the virtual crystal mean field approximations. Our results indicate that TMR is a function of spin polarization and barrier thickness. As a result of the stong spin–orbit interactions, TMR also depends on the the angle between current flow direction and the electrode magnetization. These results compromise the validity of Julliere formula.This work was supported in part by MCYT of Spain under Contract Nos.

Multi-Particle Quasi Exactly Solvable Difference Equations

Several explicit examples of multi-particle quasi exactly solvable `discrete'
quantum mechanical Hamiltonians are derived by deforming the well-known exactly
solvable multi-particle Hamiltonians, the Ruijsenaars-Schneider-van Diejen
systems. These are difference analogues of the quasi exactly solvable
multi-particle systems, the quantum Inozemtsev systems obtained by deforming
the well-known exactly solvable Calogero-Sutherland systems. They have a finite
number of exactly calculable eigenvalues and eigenfunctions. This paper is a
multi-particle extension of the recent paper by one of the authors on deriving
quasi exactly solvable difference equations of single degree of freedom.Comment: LaTeX with amsfonts, amssymb, amsmath, no figure, 12 page
Extensions of discrete classical orthogonal polynomials beyond the
  orthogonality

It is well known that the family of Hahn polynomials
$\{h_n^{\alpha,\beta}(x;N)\}_{n\ge 0}$ is orthogonal with respect to a certain
weight function up to $N$. In this paper we present a factorization for Hahn
polynomials for a degree higher than $N$ and we prove that these polynomials
can be characterized by a $\Delta$-Sobolev orthogonality.
  We also present an analogous result for dual-Hahn, Krawtchouk, and Racah
polynomials and give the limit relations between them for all $n\in \XX N_0$.
Furthermore, in order to get this results for the Krawtchouk polynomials we
will get a more general property of orthogonality for Meixner polynomials.Comment: 2 figures, 20 page
The sea urchin metallothionein system: Comparative evaluation of the SpMTA and SpMTB metal-binding preferences.

Metallothioneins (MTs) constitute a superfamily of ubiquitous metal-binding proteins of low molecular weight and high Cys content. They are involved in metal homeostasis and detoxification, amongst other proposed biological functions. Two MT isoforms (SpMTA and SpMTB) have been reported in the echinoderm Strongylocentrotus purpuratus (sea urchin), both containing 20 Cys residues and presenting extremely similar sequences, although showing distinct tissular and ontogenic expression patterns. Although exhaustive information is available for the Cd(II)-SpMTA complex, this including the full resolution of its 3D structure, no data has been reported concerning either SpMTA Zn(II) and Cu(I) binding properties, or the characterization of SpMTB at protein level. In this work, both the SpMTA and SpMTB isoforms, as well as their separate α and β domains, have been recombinantly synthesized in the presence of Zn(II), Cd(II) or Cu(II), and the corresponding metal complexes have been analyzed using electrospray mass spectrometry, and CD, ICP-AES and UV-vis spectroscopies. The results clearly show a better performance of isoform A when binding Zn(II) and Cd(II), and of isoform B when coordinating Cu(I). Thus, our results confirm the differential metal binding preference of SpMTA and SpMTB, which, together with the reported induction pattern of the respective genes, highlights how also in Echinodermata the MT polymorphism may be linked to the evolution of different physiological roles
Measurement of the differential and double-differential Drell-Yan cross sections in proton-proton collisions at √s = 7 TeV

Measurements of the differential and double-differential Drell-Yan cross sections are presented using an integrated luminosity of 4.5 (4.8) fb[superscript −1] in the dimuon (dielectron) channel of proton-proton collision data recorded with the CMS detector at the LHC at √s = 7 TeV. The measured inclusive cross section in the Z-peak region (60–120 GeV) is σ(ℓℓ) = 986.4 ± 0.6 (stat.) ± 5.9 (exp. syst.) ± 21.7 (th. syst.) ± 21.7 (lum.) pb for the combination of the dimuon and dielectron channels. Differential cross sections dσ/dm for the dimuon, dielectron, and combined channels are measured in the mass range 15 to 1500 GeV and corrected to the full phase space. Results are also presented for the measurement of the double-differential cross section d[superscript 2]σ/dm d|y| in the dimuon channel over the mass range 20 to 1500 GeV and absolute dimuon rapidity from 0 to 2.4. These measurements are compared to the predictions of perturbative QCD calculations at next-to-leading and next-to-next-to-leading orders using various sets of parton distribution functions.United States.

The dynamical behavior of $f(T)$ theory

Recently, a new model obtained from generalizing teleparallel gravity, named
$f(T)$ theory, is proposed to explain the present cosmic accelerating expansion
with no need of dark energy. In this paper, we analyze the dynamical property
of this theory. For a concrete power law model, we obtain that the dynamical
system has a stable de Sitter phase along with an unstable radiation dominated
phase and an unstable matter dominated one. We show that the Universe can
evolve from a radiation dominated era to a matter dominated one, and finally
enter an exponential expansion phase.Comment: 10 pages, 1 figure; accepted by PL
Non-uniform reionization by galaxies and its effect on the cosmic
  microwave backgroun

We present predictions for the reionization of the intergalactic medium by
stars in high-redshift galaxies. We calculate ionizing luminosities of
galaxies, including the effects of absorption by interstellar gas and dust on
the escape fraction, in order to calculate the filling factor of ionized
hydrogen in the IGM. For a $\Lambda{\rm CDM}$ cosmology and a physical
calculation of the escape fraction, we find that the hydrogen in the IGM will
be reionized at redshift z=6.1 if the IGM has uniform density, but only by
z=4.5 if the IGM is clumped. We combine our model with an N-body simulation of
the distribution of dark matter in the universe in order to calculate the
secondary temperature anisotropies induced in the cosmic microwave background
(CMB) by scattering off free electrons. The models predict a spectrum of
secondary anisotropies covering a broad range of angular scales, with
fractional temperature fluctuations $\sim 10^{-7}-10^{-6}$ on arcminute scales.
The amplitude depends somewhat on the geometry of reionization, with models in
which the regions of highest gas density are reionized first giving larger CMB
fluctuations than the case where galaxies ionize surrounding spherical regions,
and models where low density regions reionize first giving the smallest
fluctuations. Measurement of these anisotropies can therefore put important
constraints on the reionization process, in particular, the redshift evolution
of the filling factor, and should be a primary objective of a next generation
submillimeter telescope such as the Atacama Large Millimeter Array. (abrdiged)Comment: 26 pages, 19 figures, to appear in MNRAS - improved calculation of

Quintessential Inflation with Dissipative fluid

We have investigated cosmological models with a self-interacting scalar field
and a dissipative matter fluid as the sources of matter. Different variables
are expressed in terms of a {\it generating function}. Exact solutions are
obtained for one particular choice of the {\it generating function} The
potential corresponding to this generating function is a standard tree-level
potential arising in the perturbative regime in quantum field theory. With
suitable choice of parameters, the scale factor in our model exhibits both
inflationary behaviour in the early universe as well as an accelerating phase
at late times with a decelerating period in between. It also satisfies the
constraints for primeval nucleosynthesis and structure formation and seems to
solve the cosmic coincidence problem. The solution exhibits a attractor nature
towards a asymptotic de-sitter universe.Comment: 8 pages, Revtex. The title has been changed. Some new features have

Lattice study on kaon pion scattering length in the $I=3/2$ channel

Using the tadpole improved Wilson quark action on small, coarse and
anisotropic lattices, $K\pi$ scattering length in the $I=3/2$ channel is
calculated within quenched approximation. The results are extrapolated towards
the chiral and physical kaon mass region. Finite volume and finite lattice
spacing errors are also analyzed and a result in the infinite volume and
continuum limit is obtained. Our result is compared with the results obtained
using Roy equations, Chiral Perturbation Theory, dispersion relations and the
experimental data.Comment: Latex file typeset with elsart.cls, 9 pages, 3 figure
Spectroscopy of the short-hard GRB 130603B: The host galaxy and
  environment of a compact object merger

Short duration gamma-ray bursts (SGRBs) are thought to be related to the
violent merger of compact objects, such as neutron stars or black holes, which
makes them promising sources of gravitational waves. The detection of a
'kilonova'-like signature associated to the Swift-detected GRB 130603B has
suggested that this event is the result of a compact object merger. Our
knowledge on SGRB has been, until now, mostly based on the absence of supernova
signatures and the analysis of the host galaxies to which they cannot always be
securely associated. Further progress has been significantly hampered by the
faintness and rapid fading of their optical counterparts (afterglows), which
has so far precluded spectroscopy of such events. Afterglow spectroscopy is the
key tool to firmly determine the distance at which the burst was produced,
crucial to understand its physics, and study its local environment. Here we
present the first spectra of a prototypical SGRB afterglow in which both
absorption and emission features are clearly detected. Together with
multiwavelength photometry we study the host and environment of GRB 130603B.
From these spectra we determine the redshift of the burst to be z =
0.3565+/-0.0002, measure rich dynamics both in absorption and emission, and a
substantial line of sight extinction of A_V = 0.86+/-0.15 mag. The GRB was
located at the edge of a disrupted arm of a moderately star forming galaxy with
near-solar metallicity. Unlike for most long GRBs (LGRBs), N_HX / A_V is
consistent with the Galactic ratio, indicating that the explosion site differs
from those found in LGRBs. The merger is not associated with the most
star-forming region of the galaxy; however, it did occur in a dense region,
implying a rapid merger or a low natal kick velocity for the compact object
binary.Comment: Accepted for publication in Astronomy and Astrophysic
Some results from algebraic geometry over Henselian real valued fields

This paper develops algebraic geometry over Henselian real valued (i.e. of
rank 1) fields $K$, being a sequel to our paper about that over Henselian
discretely valued fields. Several results are given including: a certain
concept of fiber shrinking (a relaxed version of curve selection) for definable
sets, the canonical projection $K^{n} \times K\mathbb{P}^{m} \to K^{n}$ and
blow-ups of the $K$-points of smooth $K$-varieties are definably closed maps, a
descent property for blow-ups, a version of the Lojasiewicz inequality for
continuous rational functions and the theorem on extending continuous
hereditarily rational functions, established for the real and $p$-adic
varieties in our joint paper with J. Kollar. The descent property enables
application of desingularization and transformation to a normal crossing by
blowing up in much the same way as over the locally compact ground field. Our
approach applies quantifier elimination due to Pas.Comment: This paper was included in the article "Some results of algebraic

Extending two-Higgs-doublet models by a singlet scalar field - the Case
  for Dark Matter

We extend the two-Higgs doublet models of Type I and Type II by adding a real
gauge-singlet scalar S dark matter candidate (2HDMS models). We impose
theoretical constraints deriving from perturbativity, stability, unitarity and
correct electroweak symmetry breaking and require that the lightest CP-even
Higgs, h, fit the LHC data for the $\sim 125.5$ GeV state at the $68\%$~C.L.
after including existing constraints from LEP and B physics and LHC limits on
the heavier Higgs bosons. We find that these models are easily consistent with
the LUX and SuperCDMS limits on dark-matter-Nucleon scattering and the observed
$\Omega h^2$ for S masses above about 55 GeV. At lower $m_S$, the situation is
more delicate. For points with $m_S$ in the 6-25 GeV range corresponding to the
CDMS~II and CRESST-II positive signal ranges, the dark-matter-Nucleon cross
sections predicted by the Type I and Type II models more or less automatically
fall within the $95\%-99\%$~C.L. signal region boundaries. Were it not for the
LUX and SuperCDMS limits, which exclude all (almost all) such points in the
case of Type I (Type II), this would be a success for the 2HDMS models. In
fact, in the case of Type II there are a few points with 5.5 GeV $\leq m_S
\leq$ 6.2 GeV that survive the LUX and SuperCDMS limits and fall within the
CDMS~II 99\% C.L. signal region. Possibilities for dark matter to be
isospin-violating in this 2HDMS context are also examined.Comment: 30 pages, 20 figures, 6 table
SpeX Spectroscopy of Unresolved Very Low Mass Binaries. II.
  Identification of Fourteen Candidate Binaries with Late-M/Early-L and T Dwarf
  Components

Multiplicity is a key statistic for understanding the formation of very low
mass (VLM) stars and brown dwarfs. Currently, the separation distribution of
VLM binaries remains poorly constrained at small separations ($\leq$ 1 AU),
leading to uncertainty in the overall binary fraction. We approach this problem
by searching for late-M/early-L plus T dwarf spectral binaries whose combined
light spectra exhibit distinct peculiarities, allowing for
separation-independent identification. We define a set of spectral indices
designed to identify these systems, and use a spectral template fitting method
to confirm and characterize spectral binary (SB) candidates from a library of
815 spectra from the SpeX Prism Spectral Libraries. We present eleven new
binary candidates, confirm three previously reported candidates and rule out
two previously identified candidates, all with primary and secondary spectral
types between M7-L7 and T1-T8, respectively. We find that subdwarfs and blue L
dwarfs are the primary contaminants in our sample and propose a method for
segregating these sources. If confirmed by follow-up observations, these
systems may add to the growing list of tight separation binaries, whose orbital
properties may yield further insight into brown dwarf formation scenarios.Comment: 49 pages, 9 figures. v3 includes sigma values for table 4, and

Hint of Lepton Flavour Non-Universality in $B$ Meson Decays

The LHCb collaboration has recently presented their result on R_K = BR(B+ ->
K+ mu+ mu-)/ BR(B+ -> K+ e+ e-) for the dilepton invariant mass bin m_{ll}^2 =
1-6 GeV^2 (l = mu, e). The measurement shows an intriguing 2.6 sigma deviation
from the Standard Model (SM) prediction. In view of this, we study model
independent New Physics (NP) explanations of R_K consistent with other
measurements involving b -> s l l transition, relaxing the assumption of lepton
universality. We perform a Bayesian statistical fit to the NP Wilson
Coefficients and compare the Bayes Factors of the different hypotheses in order
to quantify their goodness-of-fit. We show that the data slightly favours NP in
the muon sector over NP in the electron sector.Comment: Final version, to appear in JHE
Inverse cascade and symmetry breaking in rapidly-rotating Boussinesq
  convection

In this paper we present numerical simulations of rapidly-rotating
Rayleigh-B\'enard convection in the Boussinesq approximation with stress-free
boundary conditions. At moderately low Rossby number and large Rayleigh number,
we show that a large-scale depth-invariant flow is formed, reminiscent of the
condensate state observed in two-dimensional flows. We show that the
large-scale circulation shares many similarities with the so-called vortex, or
slow-mode, of forced rotating turbulence. Our investigations show that at a
fixed rotation rate the large-scale vortex is only observed for a finite range
of Rayleigh numbers, as the quasi-two-dimensional nature of the flow disappears
at very high Rayleigh numbers. We observe slow vortex merging events and find a
non-local inverse cascade of energy in addition to the regular direct cascade
associated with fast small-scale turbulent motions. Finally, we show that
cyclonic structures are dominant in the small-scale turbulent flow and this
symmetry breaking persists in the large-scale vortex motion.Comment: 15 pages, 11 figures, accepted for publication in Physics of Fluid
Non-commutative Duality: High Spin Fields and $CP^1$ Model with Hopf
  Term

We show that the non-commutative $CP^1$ model coupled with Hopf term in 3
dimensions is equivalent to an interacting spin-$s$ theory where the spin $s$
of the dual theory is related to the coefficient of the Hopf term. We use the
Seiberg-Witten map in studying this non-commutative duality equivalence,
keeping terms to order $\theta$ and show that the spin of the dual theory do
not get any $\theta$ dependant corrections. The map between current correlators
show that topological index of the solitons in the non-commutative $CP^1$ model
is unaffected by $\theta$ where as the Noether charge of the corresponding dual
particle do get a $\theta$ dependence. We also show that this dual theory
smoothly goes to the limit $\theta\to 0$ giving dual theory in the commutative
plane.Comment: 13 pages, more references and a footnote are added. Version to appear

Quasi-linear equations in coframe gravity

We consider a certain variant of teleparallel gravity: a differential manifold endowed with a smooth coframe field. The differential-geometric structure on the manifold can be characterized by the objects of anholonomity and its derivative - objects of curvature. We construct a full list of the first and second order $SO(1,3)$-covariants (one- and two-indexed quantities) and a most general quasi-linear field equation with free parameters. A part of the parameters are fixed by a condition that the field equation is satisfied by a quasi-conformal coframe with a harmonic conformal function. Thus we obtain a wide class of field equations with a solution that yields to the Majumdar-Papapetrou metric and, in particularly, to a viable Yilmaz-Rosen metric
A partial wave analysis of the centrally produced $K^{+}K^{-}$ and $K^{0}_{S}K^{0}_{S}$ systems in pp interactions at 450 GeV/c and new information on the spin of the $f_{J}(1710)$

A partial wave analysis of the centrally produced K+K- and K0K0 channels has been performed in pp collisions using an incident beam momentum of 450 GeV/c. An unambiguous physical solution has been found in each channel. The striking feature is the observation of peaks in the S-wave corresponding to the f0(1500) and fJ(1710) with J = 0. The D-wave shows evidence for the f2(1270)/a2(1320), the f2(1525) and the f2(2150) but there is no evidence for a statistically significant contribution in the D-wave in the 1.7 GeV mass region
Electromagnetic Duality and $SU(3)$ Monopoles

We consider the low-energy dynamics of a pair of distinct fundamental
monopoles that arise in the $N=4$ supersymmetric $SU(3)$ Yang-Mills theory
broken to $U(1)\times U(1)$. Both the long distance interactions and the short
distance behavior indicate that the moduli space is $R^3\times(R^1 \times {\cal
M}_0)/Z$ where ${\cal M}_0$ is the smooth Taub-NUT manifold, and we confirm
this rigorously. By examining harmonic forms on the moduli space, we find a
threshold bound state of two monopoles with a tower of BPS dyonic states built
on it, as required by Montonen-Olive duality. We also present a conjecture for
the metric of the moduli space for any number of distinct fundamental monopoles
for an arbitrary gauge group.Comment: LaTeX, 11 pages (a reference is added, the mass-dependence of the
