Repeat interventions as a long-term treatment strategy in the management of progressive coronary artery disease.

Objectives. This study investigates whether repeat coronary interventions, applied over an extended time period, can successfully curtail the progression of ischemic symptoms and angiographic lumen narrowing.
Background. Coronary artery disease is a chronic and generally progressive disorder, and potential treatment strategies should be examined and compared with this chronicity in mind. Percutaneous interventional revascularization procedures could theoretically be useful in controlling progression of the disease through repeated use as new coronary lesions arise. However, the outcome of this long-term management concept has not previously been subjected to detailed investigation.
Methods. From a consecutive series of 4,357 interventional cardiac procedures, 544 patients were identified who received two or more interventions during the 13-year study period. These patients were categorized into one of three groups: restenosis (repeat interventions limited to the same target segment, N = 261), new stenosis (all repeat interventions directed to stenoses not previously treated, N = 155) or both (repeat interventions directed both to the same and to different target lesions, N = 128).
Results. Two to five procedures were performed per patient; the time period (mean ± SD) separating each procedure was significantly less (p < 0.0001) for the restenosis group (4.2 ± 2.3 months) than for the new stenosis (24.2 ± 23.5 months) or the “both” groups (11.4 ± 11.0 months). Despite the need for repeat procedures, the severity of angina (mean New York Heart Association functional class 1.6 ± 0.9) after 6.2 ± 2.3 years of follow-up was substantially better than before the initial procedure (mean functional class 3.2 ± 0.8), with a similar magnitude of change found in all three groups. This long-term functional improvement was mirrored by a corresponding anatomic improvement, with the mean number of diseased vessels remaining constant at the time of each procedure (1.5 ± 0.7, 1.5 ± 0.7 and 1.6 ± 0.7, respectively, for the first, second and third procedures, P = NS). The restenosis and the new stenosis groups also demonstrated statistically similar annual rates of mortality (1.9% vs. 1.8%) and coronary surgery (2.3% vs. 2.6%), although the restenosis group had a lower rate of infarction (1.4% vs. 3.2%, P = 0.002).

Conclusions. Repeat interventional treatment of newly acquired stenoses provides a rational approach for the long-term management of chronic coronary artery disease. In addition to yielding a favorable late outcome, the use of this strategy can result in sustained functional improvement and can check the progression of clinically significant stenoses
Susceptibility and adaptation to human TRIM5α alleles at positive selected sites in HIV-1 capsid.

Numerous in vitro studies attribute to human TRIM5α some modest anti-HIV-1 activity and human population studies suggest some differential effect of TRIM5α polymorphisms on disease progression. If the activity of TRIM5α were relevant in vivo, it could result in positive selection on the viral capsid. To address this issue, we identified 10 positively selected sites in HIV-1 capsid from multiple viral strains and generated 17 clade B viruses carrying a minor (i.e. low frequency) residue or an alanine at those positions. All recombinant viruses were susceptible to the modest effect of common human TRIM5α and allelic variants R136Q, and H419Y; H43Y and G249D TRIM5α were generally inactive. Increased sensitivity to TRIM5α was observed for some capsid variants, suggesting that minor residues are selected against in human populations. On the other hand, the modest potency of human TRIM5α does not translate in escape mutations in the viral capsid

The role played by Paleoproterozoic cratons in southern South America from the Mesoproterozoic\ud

re-assembly as Gondwana through complex oblique collisions in the Late Neoproterozoic to Early\ud

Forming impressions of personality: A replication and review of Asch's (1946) evidence for a primacy-of-warmth effect in impression formation

Contains fulltext :
                  128034-OA.pdf (publisher's version ) (Open Access)Asch's seminal research on "Forming Impressions of Personality'' (1946) has widely been cited as providing evidence for a primacy-of-warmth effect, suggesting that warmth-related judgments have a stronger influence on impressions of personality than competence-related judgments (e. g., Fiske, Cuddy, & Glick, 2007; Wojciszke, 2005). Because this effect does not fit with Asch's Gestalt-view on impression formation and does not readily follow from the data presented in his original paper, the goal of the present study was to critically examine and replicate the studies of Asch's paper that are most relevant to the primacy-of-warmth effect. We found no evidence for a primacyof- warmth effect. Instead, the role of warmth was highly context-dependent, and competence was at least as important in shaping impressions as warmth.11 p
Explicit solutions of generalized Cauchy-Riemann systems using the
  transplant operator

In [8] it was shown that the transplant operator transforms solutions of one
Vekua equation into solutions of another Vekua equation, related to the first
via a Schr\"odinger equation. In this paper we demonstrate a fundamental
property of this operator: it transforms formal powers of the first Vekua
equation into formal powers of the same order for the second Vekua equation.
This property allows us to obtain positive formal powers and a generating
sequence of a "complicated" Vekua equation from positive formal powers and a
generating sequence of "simpler" Vekua equation. Similar results is obtained
regarding construction of Cauchy kernels. Elliptic and hyperbolic
pseudoanalytic function theory are considered and examples are given to
illustrate the procedure.Comment: 18 pages, 1 figur
Long-term multi-wavelength studies of GRS 1915+105 I. A high-energy and
  mid-infrared focus with RXTE, INTEGRAL, and Spitzer

To date, mid-infrared properties of Galactic black hole binaries have barely
been investigated in the framework of multi-wavelength campaigns. Yet, studies
in this spectral domain are crucial to get complementary information on the
presence of dust and/or on the physical processes such as dust heating and
thermal bremsstrahlung. Here, we report a long-term multi-wavelength study of
the microquasar GRS 1915+105. On the one hand, we aimed at understanding the
origins of the mid-infrared emission, and on the other hand, at searching for
correlation with the high-energy and/or radio activities. We observed the
source at several epochs between 2004 and 2006 with the photometer IRAC and
spectrometer IRS, both mounted on the Spitzer Space Telescope. When available,
we completed our set of data with quasi-simultaneous RXTE and INTEGRAL
high-energy and/or Ryle radio observations from public archives. We then
studied the mid-infrared environment and activities of GRS 1915+105 through
spectral analysis and broad band fitting of its radio to X-ray spectral energy
distributions. We detected polycyclic aromatic hydrocarbon molecules in all but
one IRS spectra of GRS 1915+105 which unambiguously proves the presence of a
dust component, likely photoionised by the high-energy emission. We also argue
that this dust is distributed in a disc-like structure heated by the companion
star, as observed in some Herbig Ae/Be and isolated cool giant stars. Moreover,
we show that some of the soft X-ray emission emanating from the inner regions
of the accretion disc is reprocessed and thermalised in the outer part. This
leads to a mid-infrared excess that is very likely correlated to the soft X-ray
emission. We exclude thermal bremsstrahlung as contributing significantly in
this spectral domain.Comment: 46 pages, 6 tables, 6 figures, accepted in Ap
Discovery of "isolated" comoving T Tauri stars in Cepheus

During the course of a large spectroscopic survey of X-ray active late-type
stars in the solar neighbourhood, we discovered four lithium-rich stars packed
within just a few degrees on the sky. These very young stars are projected
several degrees away from the Cepheus-Cassiopea clouds, in front of an area
void of interstellar matter. As such, they are very good "isolated" T Tauri
star candidates. We acquired high-resolution optical spectra as well as
photometric data allowing us to investigate in detail their nature and physical
parameters with the aim of testing the "runaway" and "in-situ" formation
scenarios. We derive accurate radial and rotational velocities and perform an
automatic spectral classification. The spectral subtraction technique is used
to infer chromospheric activity level in the H-alpha line core and clean the
spectra of photospheric lines before measuring the equivalent width of the
lithium absorption line. Both physical (lithium content, magnetic activity) and
kinematical indicators show that all stars are very young (ages in the range
10-30 Myr). In particular, the spectral energy distribution of TYC4496-780-1
displays a strong near- and far-infrared excess, typical of T Tauri stars still
surrounded by an accretion disc. They also share the same Galactic motion,
proving that they form a homogeneous moving group of stars with the same
origin. The most plausible explanation of how these "isolated" T Tauri stars
formed is the "in-situ" model, although accurate distances are needed to
clarify their connection with the Cepheus-Cassiopeia complex
On root categories of finite-dimenisonal algebras

For any finite-dimensional algebra $A$ over a field $k$ with finite global
dimension, we investigate the root category $\cR_A$ as the triangulated hull of
the 2-periodic orbit category of $A$ via the construction of B. Keller in "On
triangulated orbit categories". This is motivated by Ringel-Hall Lie algebras
associated to 2-periodic triangulated categories. As an application, we study
the Ringel-Hall Lie algebras for a class of finite-dimensional $k$-algebras
with global dimension 2, which turn out to give an alternative answer for a
question of GIM Lie algebras by Slodowy in "Beyond Kac-Moody algebra, and
inside".Comment: 25 page
Global and local level dynamics in chaotic microwave billiards

The spectra of Sinai microwave billiards and rectangular billiards with
statistically distributed circular scatterers have been taken as a function of
the position of one wall, and of one of the scatterers, respectively. Whereas
in the first case the velocity distribution and correlations obey the universal
behaviour predicted by Simons and Altshuler, in the second case a completely
different behaviour is observed. This is due to the fact that a shift of one
wall changes the wave function globally whereas the displacement of one
scatterer only leads to a local perturbance.Comment: Proceedings of Localisation99, Hamburg. To appear in Annalen der

The delocalization problem of two interacting electrons in a
  two-dimensional random potential

The problem of two electrons in a two-dimensional random potential is
addressed numerically. Specifically, the role of the Coulomb interaction
between electrons on localization is investigated by writing the Hamiltonian on
a localized basis and diagonalizing it exactly. The result of that procedure is
discussed in terms of level statistics, and the expectation value of the
electron-electron separation.Comment: 4 pages, 2 figures. To be published in phys. stat. sol. (Proceedings

Direct Observation of Longitudinally Polarised W Bosons

The three different helicity states of W bosons, produced in the reaction
e+e- -> W+W- -> l nu q q~ are studied using leptonic and hadronic W decays at
sqrt{s}=183GeV and 189GeV. The W polarisation is also measured as a function of
the scattering angle between the W- and the direction of the e- beam. The
analysis demonstrates that W bosons are produced with all three helicities, the
longitudinal and the two transverse states. Combining the results from the two
center-of-mass energies and with leptonic and hadronic W decays, the fraction
of longitudinally polarised W bosons is measured to be 0.261 +/- 0.051(stat.)
+/- 0.016(syst.) in agreement with the expectation from the Standard Model
Ways to detect a light Higgs boson at the LHC

We summarize the possible processes which may be used to search for a Higgs
boson, of mass in the range 114-130 GeV, at the LHC. We discuss, in detail, two
processes with rapidity gaps: exclusive Higgs production with tagged outgoing
protons and production by Weak Boson Fusion, in each case taking H -> bbbar as
the signal. We make an extensive study of all possible bbbar backgrounds, and
discuss the relevant experimental issues. We emphasize the special features of
these signals, and of their background processes, and show that they could play
an important role in identifying a light Higgs boson at the LHC.Comment: 25 pages, 5 figure
A Light Sterile Neutrino from Friedberg-Lee Symmetry

Light sterile neutrinos of mass about an eV with mixing $\tilde U_{ls}$ of a
few percent to active neutrinos may solve some anomalies shown in experimental
data related to neutrino oscillation. How to have light sterile neutrinos is
one of the theoretical problems which have attracted a lot of attentions. In
this article we show that such an eV scale light sterile neutrino candidate can
be obtained in a seesaw model in which the right-handed neutrinos satisfy a
softly-broken Friedberg-Lee (FL) symmetry. In this model a right-handed
neutrino is guaranteed by the FL symmetry to be light comparing with other two
heavy right-handed neutrinos. It can be of eV scale when the FL symmetry is
softly broken and can play the role of eV scale sterile neutrino needed for
explaining the anomalies of experimental data. This model predicts that one of
the active neutrino is massless. We find that this model prefers inverted
hierarchy mass pattern of active neutrinos than normal hierarchy. An
interesting consequence of this model is that realizing relatively large
$|{\tilde U}_{es}|$ and relatively small $|{\tilde U}_{\mu s}|$ in this model
naturally leads to a relatively small $|{\tilde U}_{\tau s}|$. This interesting
prediction can be tested in future atmospheric or solar neutrino experiments.Comment: 14 pages, references added, version for publication in PL
Spectroscopy of High Energy BL Lac Objects with X-shooter on the VLT

Context. The study of BL Lac objects (BLL) detected in gamma-rays gives
insights on the acceleration mechanisms in play in such systems and is also a
valuable tool to constrain the density of the extragalactic background light.
As their spectra are dominated by the non-thermal emission of the jet and the
spectral features are weak and narrow in the optical domain, measuring their
redshift is challenging. However such a measure is fundamental as it allows a
firm determination of the distance and luminosity of the source, and therefore
a consistent model of its emission. Aims. Measurement of the redshift of BLL
detected in gamma-rays and determination of global properties of their host
galaxies. Methods. We observed a sample of eight BLL (KUV 00311-1938, PKS
0447-439, PKS 0301-243, BZB J0238-3116, BZB J0543-5532, BZB J0505+0415, BZB
J0816-1311 and RBS 334) with the X-shooter spectrograph installed at the ESO
Very Large Telescope in order to take advantage of its unprecedented wavelength
coverage and of its resolution about 5 times higher than generally used in such
studies. We extracted UVB to NIR spectra that we then corrected for telluric
absorption and calibrated in flux. We systematically searched for spectral
features. When possible, we determined the contribution of the host galaxy to
the overall emission. Results. Of the eight BLL, we measured the redshift of
five of them and determined lower limits for two through the detection of
intervening systems. All seven of these objects have redshifts greater than
0.2. In two cases, we refuted redshift values reported in other publications.
Through careful modelling, we determined the magnitude of the host galaxies. In
two cases, the detection of emission lines allowed to provide hints on the
overall properties of the gas in the host galaxies.Comment: 19 pages, 10 figures, 7 tables, in press on A&
Search for pair production of excited top quarks in the lepton + jets
  final state

A search is performed for pair-produced spin-3/2 excited top quarks (t*
t*-bar), each decaying to a top quark and a gluon. The search uses data
collected with the CMS detector from pp collisions at a center-of-mass energy
of sqrt(s) = 8 TeV, selecting events that have a single isolated muon or
electron, an imbalance in transverse momentum, and at least six jets, of which
one must be compatible with originating from the fragmentation of a b quark.
The data, corresponding to an integrated luminosity of 19.5 inverse femtobarns,
show no significant excess over standard model predictions, and provide a lower
limit of 803 GeV at 95% confidence on the mass of the spin-3/2 t* quark in an
extension of the Randall-Sundrum model, assuming a 100% branching fraction of
its decay into a top quark and a gluon. This is the first search for a spin-3/2
excited top quark performed at the LHC.Comment: Replaced with published version. Added journal reference and DO
Measurement of Vacuum Pressure with a Magneto-Optical Trap: a
  Pressure-Rise Method

The lifetime of an atom trap is often limited by the presence of residual
background gases in the vacuum chamber. This leads to the lifetime being
inversely proportional to the pressure. Here we use this dependence to estimate
the pressure and to obtain pressure rate-of-rise curves, which are commonly
used in vacuum science to evaluate the performance of a system. We observe
different rates of pressure increase in response to different levels of
outgassing in our system. Therefore we suggest that this is a sensitive method
which will be useful in applications of cold atom systems, in particular where
the inclusion of a standard vacuum gauge is impractical.Comment: 5 pages, 6 figure
Threshold resummation at N$^3$LL accuracy and soft-virtual cross
  sections at N$^3$LO

We consider QCD radiative corrections to the production of colourless
high-mass systems in hadron collisions. We show that the recent computation of
the soft-virtual corrections to Higgs boson production at N$^3$LO [1] together
with the universality structure of soft-gluon emission can be exploited to
extract the general expression of the hard-virtual coefficient that contributes
to threshold resummation at N$^3$LL accuracy. The hard-virtual coefficient is
directly related to the process-dependent virtual amplitude through a universal
(process-independent) factorization formula that we explicitly evaluate up to
three-loop order. As an application, we present the explicit expression of the
soft-virtual N$^3$LO corrections for the production of an arbitrary colourless
system. In the case of the Drell-Yan process, we confirm the recent result of
Ref.[2].Comment: Slightly expanded text, one reference added, version published on NP
Deviation from Bimaximal Mixing and Leptonic CP Phases in $S_4$ Family
  Symmetry and Generalized CP

The lepton flavor mixing matrix having one row or one column in common with
the bimaximal mixing up to permutations is still compatible with the present
neutrino oscillation data. We provide a thorough exploration of generating such
a mixing matrix from $S_4$ family symmetry and generalized CP symmetry
$H_{CP}$. Supposing that $S_4\rtimes H_{CP}$ is broken down to
$Z^{ST^2SU}_2\times H^{\nu}_{CP}$ in the neutrino sector and
$Z^{TST^{2}U}_4\rtimes H^{l}_{CP}$ in the charged lepton sector, one column of
the PMNS matrix would be of the form $\left(1/2, 1/\sqrt{2}, 1/2\right)^{T}$ up
to permutations, both Dirac CP phase and Majorana CP phases are trivial in
order to accommodate the observed lepton mixing angles. The phenomenological
implications of the remnant symmetry $K^{(TST^2, T^2U)}_4\rtimes H^{\nu}_{CP}$
in the neutrino sector and $Z^{SU}_{2}\times H^{l}_{CP}$ in the charged lepton
sector are studied. One row of PMNS matrix is determined to be $\left(1/2, 1/2,
-i/\sqrt{2}\right)$, and all the three leptonic CP phases can only be trivial
to fit the measured values of the mixing angles. Two models based on $S_4$
family symmetry and generalized CP are constructed to implement these model
independent predictions enforced by remnant symmetry. The correct mass
hierarchy among the charged leptons is achieved. The vacuum alignment and
higher order corrections are discussed.Comment: 44 pages, 7 figure
Three-spin Strings on AdS_5 x S^5 from N=4 SYM

Using the integrable spin chain picture we study the one-loop anomalous
dimension of certain single trace scalar operators of N=4 SYM expected to
correspond to semi-classical string states on AdS_5 x S^5 with three large
angular momenta (J_1,J_2,J_3) on S^5. In particular, we investigate the
analyticity structure encoded in the Bethe equations for various distributions
of Bethe roots. In a certain region of the parameter space our operators reduce
to the gauge theory duals of the folded string with two large angular momenta
and in another region to the duals of the circular string with angular momentum
assignment (J,J',J'), J>J'. In between we locate a critical line. We propose
that the operators above the critical line are the gauge theory duals of the
circular elliptic string with three different spins and support this by a
perturbative calculation.Comment: 13 pages, v2: refs. added, minor textual changes, v3: more refs.

Semi-infinite wedges and the conformal limit of the fermionic
  Calogero-Sutherland Model with spin $\frac{1}{2}$

The conformal limit over an anti-ferromagnetic vacuum of the fermionic spin
  $\frac{1}{2}$ Calogero-Sutherland Model is derived by using the wedge product
formalism. The space of states in the conformal limit is identified with the
Fock space of two complex fermions, or, equivalently, with a tensor product of
an irreducible level-1 module of $\slt$ and a Fock space module of the
Heisenberg algebra.The Hamiltonian and the Yangian generators of the
Calogero-Sutherland Model are represented in terms of $\slt$ currents and
bosons. At special values of the coupling constant they give rise to the
Hamiltonian and the Yangian generators of the conformal limit of the
Haldane-Shastry Model acting in an irreducible level-1 module of $\slt$. At
generic values of the coupling constant the space of states is decomposed into
irreducible representations of the Yangian.Comment: 26 pages, AMSLaTe
