Sensitivities of in vivo markers of arterial organ damage in patients with peripheral atherosclerosis

BACKGROUND  Biomarkers of vascular diseases such as ankle-brachial index (ABI), peripheral pulse pressure (pPP), central pulse pressure (cPP), and pulse wave velocity (PWV) allow assessment of arterial organ damage (AOD). However, the utility of markers other than ABI in patients with peripheral arterial disease (PAD), which are also associated with a significant increase of cardiovascular events, remains unclear.  PATIENTS AND METHODS  Asymptomatic (n = 21) and symptomatic patients (n = 46) with a positive sonography for PAD or history of lower limb revascularization were included. ABI, pPP, cPP, and PWV were assessed. PWV were performed using a brachial cuff-based method (aortic PWV (aPWV)) and oscillography (carotid-femoral pulse wave velocity (cfPWV)), respectively. The two methods for PWV were compared using Bland Altman analysis. Sensitivities of ABI, pPP, cPP, cfPWV, and aPWV for AOD were calculated.  RESULTS  Sixty-seven patients (35.8 % female, mean age 69, range 39-91 years) had a significantly higher aPWV than cfPWV (median 10.5 m/s (IQR: 8.8-12.65 m/s) vs. median 9.0 m/s (IQR: 7.57-10.55 m/s), p = 0.0013). There was no correlation between cfPWV and age (r = 0.311, p = 0.116). Bland Altman analysis revealed a mean difference of -1.04 (-2SD; -6.38 to + 2SD; 4.31). The sensitivities for AOD were 68.7 % for ABI, 61.2 % for aPWV, 40.3 % for cfPWV, 31.3 % for peripheral PP, and 10.4 % for central aortic PP (p < 0.001).  CONCLUSIONS  Brachial-derived aPWV differs from the gold standard assessment (cfPWV), which may be underestimated in PAD due to atherosclerotic obstructions along the aorto-iliac segment. The sensitivities of noninvasive in vivo markers of AOD vary widely and tend to underestimate the actual presence of AOD
Cross section of ??-induced reactions on iridium isotopes obtained from thick target yield measurement for the astrophysical ?? process

These rates are usually derived from statistical model calculations, which need to be validated, but the experimental database is very scarce. This paper presents the results of ??-induced reaction cross section measurements on iridium isotopes carried out at first close to the astrophysically relevant energy region. Thick target yields of 191Ir(??,??)195Au, 191Ir(??,n)194Au, 193Ir(??,n)196mAu, 193Ir(??,n)196Au reactions have been measured with the activation technique between E??=13.4 MeV and 17 MeV. For the first time the thick target yield was determined with X-ray counting. This led to a previously unprecedented sensitivity. From the measured thick target yields, reaction cross sections are derived and compared with statistical model calculations. The recently suggested energy-dependent modification of the ?? + nucleus optical potential gives a good description of the experimental data
Symbiotic stars in X-rays. II. Faint sources detected with XMM-Newton and Chandra

We report the detection from four symbiotic stars that were not known to be X-ray sources. These four object show a β-type X-ray spectrum, that is, their spectra can be modeled with an absorbed optically thin thermal emission with temperatures of a few million degrees. Photometric series obtained with the Optical Monitor on board XMM-Newton from V2416 Sgr and NSV 25735 support the proposed scenario where the X-ray emission is produced in a shock-heated region inside the symbiotic nebulae.Fil: Nuñez, Natalia Edith.

Absence of U(1) anomalous superamplitudes in N ≥ 5 supergravities

We list all potential candidates for U(1) anomalous non-local 1-loop 4-point amplitudes and higher loop UV divergences in N ≥ 5 supergravities. The relevant chiral superinvariants are constructed from linearized chiral superfields and define the corresponding superamplitudes. The anomalous amplitudes, of the kind present in N = 4, are shown to be absent in N ≥ 5. In N = 6 supergravity the result is deduced from the double-copy (N = 4) Y M × (N = 2) Y M model, whereas in N = 5, 8 the result on absence of anomalous amplitudes is derived in supergravities as well as in the (N = 4) Y M × (N − 4) Y M double-copy models
Development of EnergyCalc - a tool to assess cotton on-farm energy uses

Within highly mechanised agricultural productions systems such as the Australian cotton industry, operational energy inputs represent a significant cost to growers. Overall, it has been estimated that machinery may contribute 40-50% of the cotton farm input costs. In this project, a framework to assess the operational energy inputs of various production systems and the relative performance of a grower within an adopted system is developed. This framework is later implemented and incorporated into a user-friendly energy assessment tool (a Betta version web-enabled online energy calculator, EnergyCalc).
N270 sensitivity to conflict strength and working memory: A combined ERP and sLORETA study

The event-related potential N270 component is known to be an electrophysiological marker of the supramodal conflict processing. However little is know about the factors that may modulate its amplitude. In particular, among all studies that have investigated the N270, little or no control of the conflict strength and of the load in working memory have been done leaving a lack in the understanding of this component. We designed a spatial audiovisual conflict task with simultaneous target and cross-modal distractor to evaluate the N270 sensitivity to the conflict strength (i.e., visual target with auditory distractor or auditory target with visual distractor) and the load in working memory (goal task maintenance with frequent change in the target modality). In a first session, participants had to focus on one modality for the target position to be considered (left-hand or right-hand) while the distractor could be at the same side (compatible) or at opposite side (incompatible). In a second session, we used the same set of stimuli as in the first session with an additional distinct auditory signal that clued the participants to frequently switch between the auditory and the visual targets. We found that (1) reaction times and N270 amplitudes for conflicting situations were larger within the auditory target condition compared to the visual one, (2) the increase in target maintenance effort led to equivalent increase of both reaction times and N270 amplitudes within all conditions and (3) the right dorsolateral prefrontal cortex current density was higher for both conflicting and active maintenance of the target situations. These results provide new evidence that the N270 component is an electrophysiological marker of the supramodal conflict processing that is sensitive to the conflict strength and that conflict processing and active maintenance of the task goal are two functions of a common executive attention system
Brief report : just-in-time visual supports to children with autism via the Apple Watch® : a pilot feasibility study

Using augmented input might be an effective
means for supplementing spoken language for children
with autism who have difficulties following spoken directives.
This study aimed to (a) explore whether JIT-delivered
scene cues (photos, video clips) via the Apple Watch®
enable children with autism to carry out directives they
were unable to implement with speech alone, and (b) test
the feasibility of the Apple Watch ®  (with a focus on display
size). Results indicated that the hierarchical JIT supports
enabled five children with autism to carry out the
majority of directives. Hence, the relatively small display
size of the Apple Watch does not seem to hinder children
with autism to glean critical information from visual
supports.http://link.springer.com/journal/108032017-12-31hb2017Centre for Augmentative and Alternative Communication (CAAC
QCD glueball Regge trajectory and the pomeron

Implementing many-body techniques successful in other fields, we report a glueball Regge trajectory emerging from diagonalizing a confining Coulomb gauge Hamiltonian for constituent gluons. Through a BCS vacuum ansatz and gap equation, the dressed gluons acquire a dynamic mass, of order 0.8 GeV, providing the quasiparticle degrees of freedom for a TDA glueball formulation. The TDA eigenstates for two constituent gluons have orbital, L, excitations with a characteristic energy of 0.4 GeV revealing a clear Regge trajectory. In particular, the J(PC) = 2(++) glueball coincides with the pomeron given by alpha(P)(t) = 1.08  (0.25 GeV-2)t. We also ascertain that lattice data supports our result. Finally, we conjecture on the odderon puzzle. \ud

Study of forward Z + jet production in pp collisions at √s = 7 TeV

A measurement of the Z(→ μ [superscript +] μ [superscript −]) + jet production cross-section in pp collisions at a centre-of-mass energy √s = 7 TeV is presented. The analysis is based on an integrated luminosity of 1.0 fb[superscript −1] recorded by the LHCb experiment. Results are shown with two jet transverse momentum thresholds, 10 and 20 GeV, for both the overall cross-section within the fiducial volume, and for six differential cross-section measurements. The fiducial volume requires that both the jet and the muons from the Z boson decay are produced in the forward direction (2.0 < η < 4.5). The results show good agreement with theoretical predictions at the second-order expansion in the coupling of the strong interaction.National Science Foundation (U.S.
Safety management in repair, maintenance, minor alteration, and addition works : knowledge management perspective

Safety of repair, maintenance, alteration, and addition (RMAA) works have long been neglected because RMAAworks are often minute and only last for a short period of time. With rising importance of the RMAA sector in many developed societies, safety of RMAA works has begun to draw attention. Many RMAA contracting companies are small- and medium-sized enterprises (SMEs) that do not have\ud
comprehensive safety management systems. Existing safety legislation and regulations for new construction sites are not fully applicable to RMAAworks. Instead of relying on explicit and well-established safety systems, tacit safety knowledge plays an extremely important role in RMAA projects. To improve safety of RMAAworks, safety knowledge should be better managed. However, safety knowledge is difficult to capture in RMAA works. This study aims to examine safety management practices of RMAA contracting companies to see how safety knowledge of RMAA projects is managed. Findings show that RMAA contracting companies undertaking large-scale RMAA projects have more initiatives of safety management. Safety management of small-scale RMAA works relies heavily on the motivation of site supervisors\ud
and self-regulation of workers. Better tacit knowledge management improves safety performance. To enhance safety capability of RMAA contracting companies, a knowledge sharing culture should be cultivated. The government should provide assistance to SMEs to implement proper safety management practices in small-sized projects. Potentials of applying computer software technology in RMAA projects to\ud
capture, store, and retrieve safety information should be explored. Employees should be motivated to share safety knowledge by giving proper recognition to those who are willing to share
Extended MacMahon-Schwinger's Master Theorem and Conformal Wavelets in
  Complex Minkowski Space

We construct the Continuous Wavelet Transform (CWT) on the homogeneous space
(Cartan domain) D_4=SO(4,2)/(SO(4)\times SO(2)) of the conformal group SO(4,2)
(locally isomorphic to SU(2,2)) in 1+3 dimensions. The manifold D_4 can be
mapped one-to-one onto the future tube domain C^4_+ of the complex Minkowski
space through a Cayley transformation, where other kind of (electromagnetic)
wavelets have already been proposed in the literature. We study the unitary
irreducible representations of the conformal group on the Hilbert spaces
L^2_h(D_4,d\nu_\lambda) and L^2_h(C^4_+,d\tilde\nu_\lambda) of square
integrable holomorphic functions with scale dimension \lambda and continuous
mass spectrum, prove the isomorphism (equivariance) between both Hilbert
spaces, admissibility and tight-frame conditions, provide reconstruction
formulas and orthonormal basis of homogeneous polynomials and discuss symmetry
properties and the Euclidean limit of the proposed conformal wavelets. For that
purpose, we firstly state and prove a \lambda-extension of Schwinger's Master
Theorem (SMT), which turns out to be a useful mathematical tool for us,
particularly as a generating function for the unitary-representation functions
of the conformal group and for the derivation of the reproducing (Bergman)
kernel of L^2_h(D_4,d\nu_\lambda). SMT is related to MacMahon's Master Theorem
(MMT) and an extension of both in terms of Louck's SU(N) solid harmonics is
also provided for completeness. Convergence conditions are also studied.Comment: LaTeX, 40 pages, three new Sections and six new references added. To

Simultaneous analysis of elastic scattering and transfer/breakup
  channels for the 6He+208Pb reaction at energies near the Coulomb barrier

The elastic and alpha-production channels for the 6He+208Pb reaction are
investigated at energies around the Coulomb barrier (E_{lab}=14, 16, 18, 22,
and 27 MeV). The effect of the two-neutron transfer channels on the elastic
scattering has been studied within the Coupled-Reaction-Channels (CRC) method.
We find that the explicit inclusion of these channels allows a simultaneous
description of the elastic data and the inclusive alpha cross sections at
backward angles. Three-body Continuum-Discretized Coupled-Channels (CDCC)
calculations are found to reproduce the elastic data, but not the
transfer/breakup data. The trivially-equivalent local polarization potential
(TELP) derived from the CRC and CDCC calculations are found to explain the
features found in previous phenomenological optical model calculations for this
system.Comment: 7 pages, 6 figures (replaced with updated version
Uncertainty Principles and Balian-Low type Theorems in Principal
  Shift-Invariant Spaces

In this paper, we consider the time-frequency localization of the generator
of a principal shift-invariant space on the real line which has additional
shift-invariance. We prove that if a principal shift-invariant space on the
real line is translation-invariant then any of its orthonormal (or Riesz)
generators is non-integrable. However, for any $n\ge2$, there exist principal
shift-invariant spaces on the real line that are also $\nZ$-invariant with an
integrable orthonormal (or a Riesz) generator $\phi$, but $\phi$ satisfies
$\int_{\mathbb R} |\phi(x)|^2 |x|^{1+\epsilon} dx=\infty$ for any $\epsilon>0$
and its Fourier transform $\hat\phi$ cannot decay as fast as $ (1+|\xi|)^{-r}$
for any $r>1/2$. Examples are constructed to demonstrate that the above decay
properties for the orthormal generator in the time domain and in the frequency
domain are optimal
First Order Metal-Insulator Transition in Two-dimensional Disordered
  Systems

In the absence of magnetic field or spin-orbit coupling the one-parameter
scaling theory predicts localization of all states in two-dimensional (2D)
disordered systems, for any amount of disorder. However, a 2D metallic phase
has been recently reported in high mobility Si-MOS and GaAs-based materials
without magnetic field. We study numerically a recently proposed 2D model which
consists of a compactly coupled pure-random plane structure. This allows to
obtain exactly a continuum of one-dimensional ballistic extended states which
can lead to a marginal metallic phase of finite conductivity
$\sigma_{0}=2e^2/h$, in a wide energy range whose boundaries define the
mobility edges of a first-order metal-insulator transition. We present
numerical diagonalization results and the conductivity of the system in
perpendicular magnetic field, which verify the above analytical predictions.
The model is also discussed in connection to recent experiments.Comment: 10 pages,5 figures, published in the proceedings of PILS'98, Annalen

Method for Determination of $|U_{e3}|$ in Neutrino Oscillation
  Appearance Experiments

We point out that determination of the MNS matrix element |U_{e3}| = s_{13}
in long-baseline \nu_{\mu} \to \nu_e neutrino oscillation experiments suffers
from large intrinsic uncertainty due to the unknown CP violating phase \delta
and sign of \Delta m^2_{13}. We propose a new strategy for accurate
determination of $\theta_{13}$; tune the beam energy at the oscillation maximum
and do the measurement both in neutrino and antineutrino channels. We show that
it automatically resolves the problem of parameter ambiguities which involves
\delta, \theta_{13}, and the sign of \Delta m^2_{13}.Comment: 15 pages, 3 figures, minor corrections, final version to appear in

The Virtual Photon-Gluon Impact Factor with Massive Quarks and Exact
  Gluon Kinematics

We calculate the impact factor coupling a virtual photon to a gluon via a
massive quark-antiquark pair at LL order, but with the imposition of the
correct gluon kinematics. Exact analytical results are presented in triple
Mellin space with respect to scaled Bjorken x, gluon transverse momentum and
heavy quark mass. The application of these results to the calculation of
approximate NLL coefficient functions needed to relate structure functions to
the BFKL gluon is presented. The NLL effects with running coupling are seen to
lead to a suppression of the small x divergence when compared with the fixed
and running coupling LL results, but less than in the massless case.Comment: 12 pages, 1 figur
Global bifurcations to subcritical magnetorotational dynamo action in
  Keplerian shear flow

Magnetorotational dynamo action in Keplerian shear flow is a
three-dimensional, nonlinear magnetohydrodynamic process whose study is
relevant to the understanding of accretion and magnetic field generation in
astrophysics. Transition to this form of dynamo is subcritical and shares many
characteristics of transition to turbulence in non-rotating hydrodynamic shear
flows. This suggests that these different fluid systems become active through
similar generic bifurcation mechanisms, which in both cases have eluded
detailed understanding so far. In this paper, we investigate numerically the
bifurcation mechanisms at work in the incompressible Keplerian
magnetorotational dynamo problem in the shearing box framework. Using numerical
techniques imported from dynamical systems research, we show that the onset of
chaotic dynamo action at magnetic Prandtl numbers larger than unity is
primarily associated with global homoclinic and heteroclinic bifurcations of
nonlinear magnetorotational dynamo cycles. These global bifurcations are
supplemented by local bifurcations of cycles marking the beginning of
period-doubling cascades. This suggests that nonlinear magnetorotational dynamo
cycles provide the pathway to turbulent injection of both kinetic and magnetic
energy in incompressible magnetohydrodynamic Keplerian shear flow in the
absence of an externally imposed magnetic field. Studying the nonlinear physics
and bifurcations of these cycles in different regimes and configurations may
subsequently help to better understand the conditions of excitation of
magnetohydrodynamic turbulence and instability-driven dynamos in various
astrophysical systems and laboratory experiments. The detailed characterization
of global bifurcations provided for this three-dimensional subcritical fluid
dynamics problem may also prove useful for the problem of transition to
turbulence in hydrodynamic shear flows.Comment: 43 pages, 17 figures, accepted for publication in J. Fluid Mec
BCS Instability and Finite Temperature Corrections to Tachyon Mass in
  Intersecting D1-Branes

A holographic description of BCS superconductivity is given in
arxiv:1104.2843. This model was constructed by insertion of a pair of D8-branes
on a D4-background. The spectrum of intersecting D8-branes has tachyonic modes
indicating an instability which is identified with the BCS instability in
superconductors. Our aim is to study the stability of the intersecting branes
under finite temperature effects. Many of the technical aspects of this problem
are captured by a simpler problem of two intersecting D1-branes on flat
background. In the simplified set-up we compute the one-loop finite temperature
corrections to the tree-level tachyon mass using the frame-work of SU(2)
Yang-Mills theory in (1 + 1)-dimensions. We show that the one-loop two-point
functions are ultraviolet finite due to cancellation of ultraviolet divergence
between the amplitudes containing bosons and fermions in the loop. The
amplitudes are found to be infrared divergent due to the presence of massless
fields in the loops. We compute the finite temperature mass correction to all
the massless fields and use these temperature dependent masses to compute the
tachyonic mass correction. We show numerically the existence of a transition
temperature at which the effective mass of the tree-level tachyons becomes
zero, thereby stabilizing the brane configuration.Comment: Article, 95 pages, 59 figures, improved numerics, added reference
The Kepler-10 planetary system revisited by HARPS-N: A hot rocky world
  and a solid Neptune-mass planet

Kepler-10b was the first rocky planet detected by the Kepler satellite and
con- firmed with radial velocity follow-up observations from Keck-HIRES. The
mass of the planet was measured with a precision of around 30%, which was
insufficient to constrain models of its internal structure and composition in
detail. In addition to Kepler-10b, a second planet transiting the same star
with a period of 45 days was sta- tistically validated, but the radial
velocities were only good enough to set an upper limit of 20 Mearth for the
mass of Kepler-10c. To improve the precision on the mass for planet b, the
HARPS-N Collaboration decided to observe Kepler-10 intensively with the HARPS-N
spectrograph on the Telescopio Nazionale Galileo on La Palma. In to- tal, 148
high-quality radial-velocity measurements were obtained over two observing
seasons. These new data allow us to improve the precision of the mass
determina- tion for Kepler-10b to 15%. With a mass of 3.33 +/- 0.49 Mearth and
an updated radius of 1.47 +0.03 -0.02 Rearth, Kepler-10b has a density of 5.8
+/- 0.8 g cm-3, very close to the value -0.02 predicted by models with the same
internal structure and composition as the Earth. We were also able to determine
a mass for the 45-day period planet Kepler-10c, with an even better precision
of 11%. With a mass of 17.2 +/- 1.9 Mearth and radius of 2.35 +0.09 -0.04
Rearth, -0.04 Kepler-10c has a density of 7.1 +/- 1.0 g cm-3. Kepler-10c
appears to be the first strong evidence of a class of more massive solid
planets with longer orbital periods.Comment: 44 pages, 8 figures, accepted for publication in Ap
