Angiographic Findings and Outcome in Diabetec Patients Treated With Thrombolytic Therapy for Acute Myocardial Infarction: The GUSTO-I Experience

OBJECTIVES: This study sought to determine whether diabetes mellitus, in the setting of thrombolysis for acute myocardial infarction, affects 1) early infarct-related artery patency and reocclusion rates; and 2) global and regional ventricular function indexes. We also sought to assess whether angiographic or baseline clinical variables, or both, can account for the known excess mortality after myocardial infarction in the diabetic population. BACKGROUND: Mortality after acute myocardial infarction in patients with diabetes is approximately twice that of nondiabetic patients. It is uncertain whether this difference in mortality is due to a lower rate of successful thrombolysis, increased reocclusion after successful thrombolysis, greater ventricular injury or a more adverse angiographic or clinical profile in diabetic patients. METHODS: Patency rates and global and regional left ventricular function were determined in patients enrolled in the GUSTO-I Angiographic Trial. Thirty-day mortality differences between those with and without diabetes were compared. RESULTS: The diabetic cohort had a significantly higher proportion of female and elderly patients, and they were more often hypertensive, came to the hospital later and had more congestive heart failure and a higher number of previous myocardial infarctions and bypass surgery procedures. Ninety-minute patency (Thrombolysis in Myocardial Infarction [TIMI] flow grade 3) rates in patients with and without diabetes were 40.3% and 37.6%, respectively (p = 0.7). Reocclusion rates were 9.2% vs. 5.3% (p = 0.17). Ejection fraction at 90 min after thrombolysis was similar in diabetic and nondiabetic patients ([mean +/- SEM] 6.10 +/- 1.6% vs. 60.1 +/- 0.7%, p = 0.7), as was regional ventricular function (number of abnormal chords: 19.1 +/- 2.0 vs. 17.5 +/- 0.8, p = 0.3; SD/chord: -2.3 +/- 0.2 vs. -2.4 +/- 0.1, p = 0.6). Diabetic patients had less compensatory hyperkinesia in the noninfarct zone (SD/ chord: 1.3 +/- 0.2 vs. 1.7 +/- 0.1, p < or = 0.01). No significant difference in ventricular function was noted at 5- to 7-day follow-up. The 30-day mortality rate was 11.3% in diabetic versus 5.9% in nondiabetic patients (p < or = 0.0001). After adjustment for clinical and angiographic variables, diabetes remained an independent determinant of 30-day mortality (p = 0.02). CONCLUSIONS: Early (90-min) infarct-related artery patency as well as regional and global ventricular function do not differ between patients with and without diabetes after thrombolytic therapy, except for reduced compensatory hyperkinesia in the noninfarct zone among patients with diabetes. Diabetes remained an independent determinant of 30-day mortality after correction for clinical and angiographic variables
The Digital Competence as a Cross-Cutting axis of Higher Education Teachers' Pedagogical Competences in the European Higher Education Area

The European Higher Education Area (EHEA) establishes a new educational paradigm centered on student and learning. It involves fundamental changes in university professor's professional tasks, therefore, they should adapt their professional profile according to the new context demands, specially those derived from the impact of ICT over it. Fruit of the convergence of two research projects that combined diverse research tools and techniques in real HE contexts, we have reflected on our findings and conclusions to build a pedagogical competences profile for HE teachers, more adequate to the current context and new training scenarios, incorporating a set of digital competences that we found as cross-cutting axis, not only for the teaching role, but for the rest of the professional roles that rise up as relevant in the recent educational context drawn by the EHEA and the Knowledge Society (KS)
Fitness landscape of the cellular automata majority problem: View from
  the Olympus

In this paper we study cellular automata (CAs) that perform the computational
Majority task. This task is a good example of what the phenomenon of emergence
in complex systems is. We take an interest in the reasons that make this
particular fitness landscape a difficult one. The first goal is to study the
landscape as such, and thus it is ideally independent from the actual
heuristics used to search the space. However, a second goal is to understand
the features a good search technique for this particular problem space should
possess. We statistically quantify in various ways the degree of difficulty of
searching this landscape. Due to neutrality, investigations based on sampling
techniques on the whole landscape are difficult to conduct. So, we go exploring
the landscape from the top. Although it has been proved that no CA can perform
the task perfectly, several efficient CAs for this task have been found.
Exploiting similarities between these CAs and symmetries in the landscape, we
define the Olympus landscape which is regarded as the ''heavenly home'' of the
best local optima known (blok). Then we measure several properties of this
subspace. Although it is easier to find relevant CAs in this subspace than in
the overall landscape, there are structural reasons that prevent a searcher
from finding overfitted CAs in the Olympus. Finally, we study dynamics and
performance of genetic algorithms on the Olympus in order to confirm our
analysis and to find efficient CAs for the Majority problem with low
computational cost
Study of CP violation in D->VV decay at BESIII

In this paper, we intend to study the problem of CP violation in $D$ meson by
$D\to VV$ decay mode in which the T violating triple-product correlation is
examined. That would undoubtedly be another excellent probe of New Physics
beyond Standard Model. For the neutral $D$, we focus on direct CP violation
without considering $D^0-\bar D^0$ oscillation. Experimentally, by a full
angular analysis one may obtain such CP violating signals, and particularly it
is worth mentioning that the upcoming large $D$ data samples at BES-III in
Beijing will provide a great opportunity to perform it.Comment: 5 pages, 2 tables and 1 figure, version to appear in Phys. Lett.
The Herschel Virgo cluster survey: V. Star-forming dwarf galaxies - dust
  in metal-poor environments

We present the dust properties of a small sample of Virgo cluster dwarf
galaxies drawn from the science demonstration phase data set of the Herschel
Virgo Cluster Survey. These galaxies have low metallicities (7.8 < 12 +
log(O/H) < 8.3) and star-formation rates < 10^{-1} M_{sun}/yr. We measure the
spectral energy distribution (SED) from 100 to 500 um and derive dust
temperatures and dust masses. The SEDs are fitted by a cool component of
temperature T < 20 K, implying dust masses around 10^{5} M_{sun} and
dust-to-gas ratios D within the range 10^{-3}-10^{-2}. The completion of the
full survey will yield a larger set of galaxies, which will provide more
stringent constraints on the dust content of star-forming dwarf galaxies.Comment: Letter accepted for publication in A&A (Herschel special issue
Fractal curvature measures and Minkowski content for one-dimensional
  self-conformal sets

We show that the fractal curvature measures of invariant sets of
one-dimensional conformal iterated function systems satisfying the open set
condition exist, if and only if the associated geometric potential function is
nonlattice. Moreover, in the nonlattice situation we obtain that the Minkowski
content exists and prove that the fractal curvature measures are constant
multiples of the $\delta$-conformal measure, where $\delta$ denotes the
Minkowski dimension of the invariant set. For the first fractal curvature
measure, this constant factor coincides with the Minkowski content of the
invariant set. In the lattice situation we give sufficient conditions for the
Minkowski content of the invariant set to exist, contrasting the fact that the
Minkowski content of a self-similar lattice fractal never exists. However,
every self-similar set satisfying the open set condition exhibits a Minkowski
measurable $\mathcal{C}^{1+\alpha}$ diffeomorphic image. Both in the lattice
and nonlattice situation average versions of the fractal curvature measures are
shown to always exist.Comment: 36 page
Off-diagonal disorder in the Anderson model of localization

We examine the localization properties of the Anderson Hamiltonian with
additional off-diagonal disorder using the transfer-matrix method and
finite-size scaling. We compute the localization lengths and study the
metal-insulator transition (MIT) as a function of diagonal disorder, as well as
its energy dependence. Furthermore we investigate the different influence of
odd and even system sizes on the localization properties in quasi
one-dimensional systems. Applying the finite-size scaling approach in
conjunction with a nonlinear fitting procedure yields the critical parameters
of the MIT. In three dimensions, we find that the resulting critical exponent
of the localization length agrees with the exponent for the Anderson model with
pure diagonal disorder.Comment: 12 pages including 4 EPS figures, accepted for publication in phys.

Supersymmetry and the Supergravity Landscape

In the recent times a lot of effort has been devoted to improve our knowledge
about the space of string theory vacua (``the landscape'') to find statistical
grounds to justify how and why the theory selects its vacuum. Particularly
interesting are those vacua that preserve some supersymmetry, which are always
supersymmetric solutions of some supergravity theory. After an general
introduction to how the pursuit of unification has lead to the vacuum selection
problem, we are going to review some recent results on the problem of finding
all the supersymmetric solutions of a supergravity theory applied to the
N=4,d=4 supergravity case.Comment: Enlarged version of the talks given at the Pomeranian Workshop on

First measurement of the double-inclusive B/Bbar hadron energy
  distribution in e+e- annihilations, and of angle-dependent moments of the B
  and Bbar energies

We have made the first measurement of the double-inclusive B/Bbar energy
distribution in e+e- annihilations, using a sample of 400,000 hadronic Z0 decay
events recorded in the SLD experiment at SLAC between 1996 and 1998. The small
and stable SLC beam spot and the CCD-based vertex detector were used to
reconstruct B/Bbar decay vertices with high efficiency and purity, and to
provide measurements of the kinematic quantities used to calculate the B
energies in this novel technique. We measured the B/Bbar energies with good
efficiency and resolution over the full kinematic range. We measured moments of
the scaled energies of the B and Bbar hadrons vs. the opening angle between
them. By comparing these results with perturbative QCD predictions we tested
the ansatz of factorisation in heavy-quark production. A recent next-to-leading
order calculation reproduces the data.Comment: 17 pages, 6 figures; submitted to Physics Letters
Fundamental Constants at High Energy

The progress of Particle Physics is closely linked to the progress in the
understanding of the fundamental constants, like the finestructure constant,
the mass of the electron or nucleon, or the electroweak mixing angle. The
relation between the 18 fundamental constants of the Standard Model and the
elementary units used in other fields like quantum optics or solid state
physics is far from trivial and will be discussed. Relations between the
various constants might exist, providing signals for the physics beyond the
Standard Model. Recent observations in astrophysics indicate a slight time
variation of the finestructure constant. If true, it has profound implications
for many particle and nuclear physics phenomena. In particular the nuclear mass
scale should change in time, a phenomenon which could be observed in the
laboratory using advanced methods of quantum optics.Comment: 8 page
Meson production in nucleon--nucleon collisions close to the threshold

The last decade has witnessed great experimental progress that has led to
measurements of cross sections--polarized as well as unpolarized--of of high
accuracy in several $NN \to NNx$ reaction channels. These data, naturally, pose
challenges to theorists to develop methods by which they can be understood and
explained in commensurate detail.
  In this work we review the status of the theory with special emphasis on
model--independent methods. We discuss in detail not only the many observables
involved in the reactions, but also the physical questions that can be
addressed by studying them in the various reaction channels. The special
advantages of nucleon--nucleon induced reactions are stressed. Foremost among
these is the use of the initial and final states as a spin/isospin filter. This
opens, for example, a window into the spin dependence of the hyperon--nucleon
interaction and the dynamics of the light scalar mesons.Comment: Typos corrected, discussion on polarization observables extended;

Classically Scale-invariant B-L Model and Conformal Gravity

We consider a coupling of conformal gravity to the classically
scale-invariant B-L extended standard model which has been recently proposed as
a phenomenologically viable model realizing the Coleman-Weinberg mechanism of
breakdown of the electro-weak symmetry. As in a globally scale-invariant
dilaton gravity, it is also shown in a locally scale-invariant conformal
gravity that without recourse to the Coleman-Weinberg mechanism, the B-L gauge
symmetry is broken in the process of spontaneous symmetry breakdown of the
local scale invariance (Weyl invariance) at the tree level and as a result the
B-L gauge field becomes massive via the Higgs mechanism. As a bonus of
conformal gravity, the massless dilaton field does not appear and the
parameters in front of the non-minimal coupling of gravity are completely fixed
in the present model. This observation clearly shows that the conformal gravity
has a practical application even if the scalar field does not possess any
dynamical degree of freedom owing to the local scale symmetry.Comment: Published version. arXiv admin note: text overlap with

Encoding the infrared excess (IRX) in the NUVrK color diagram for
  star-forming galaxies

We present an empirical method of assessing the star formation rate (SFR) of
star-forming galaxies based on their locations in the rest-frame color-color
diagram (NUV-r) vs (r-K). By using the Spitzer 24 micron sample in the COSMOS
field (~16400 galaxies with 0.2 < z < 1.3) and a local GALEX-SDSS-SWIRE sample
(~700 galaxies with z < 0.2), we show that the mean infrared excess <IRX>= <
L_IR / L_UV > can be described by a single vector, NRK, that combines the two
colors. The calibration between <IRX> and NRK allows us to recover the IR
luminosity, L_IR, with an accuracy of ~0.21 dex for the COSMOS sample and ~0.27
dex for the local one. The SFRs derived with this method agree with the ones
based on the observed (UV+IR) luminosities and on the spectral energy
distribution fitting for the vast majority (~85 %) of the star-forming
population. Thanks to a library of model galaxy SEDs with realistic
prescriptions for the star formation history, we show that we need to include a
two-component dust model (i.e., birth clouds and diffuse ISM) and a full
distribution of galaxy inclinations in order to reproduce the behavior of the
<IRX> stripes in the NUVrK diagram. In conclusion, the NRK method, based only
on rest-frame UV and optical colors available in most of the extragalactic
fields, offers a simple alternative of assessing the SFR of star-forming
galaxies in the absence of far-IR or spectral diagnostic observations.Comment: 21 pages, 22 figures, in publication in Astronomy & Astrophysic
Solvable Group Representations and Free Divisors whose Complements are
  $K(\pi, 1)$'s

We apply previous results on the representations of solvable linear algebraic
groups to construct a new class of free divisors whose complements are $K(\pi,
1)$'s. These free divisors arise as the exceptional orbit varieties for a
special class of "block representations" and have the structure of
determinantal arrangements.
  Among these are the free divisors defined by conditions for the (modified)
Cholesky-type factorizations of matrices, which contain the determinantal
varieties of singular matrices of various types as components. These
complements are proven to be homotopy tori, as are the Milnor fibers of these
free divisors. The generators for the complex cohomology of each are given in
terms of forms defined using the basic relative invariants of the group
representation.Comment: 19 pages, pdflatex. Reviewed as MR2868903, Zbl 1257.55010. NOTICE:

Non-Hermitian systems of Euclidean Lie algebraic type with real
  eigenvalue spectra

We study several classes of non-Hermitian Hamiltonian systems, which can be
expressed in terms of bilinear combinations of Euclidean Lie algebraic
generators. The classes are distinguished by different versions of antilinear
(PT)-symmetries exhibiting various types of qualitative behaviour. On the basis
of explicitly computed non-perturbative Dyson maps we construct metric
operators, isospectral Hermitian counterparts for which we solve the
corresponding time-independent Schroedinger equation for specific choices of
the coupling constants. In these cases general analytical expressions for the
solutions are obtained in the form of Mathieu functions, which we analyze
numerically to obtain the corresponding energy eigenspectra. We identify
regions in the parameter space for which the corresponding spectra are entirely
real and also domains where the PT symmetry is spontaneously broken and
sometimes also regained at exceptional points. In some cases it is shown
explicitly how the threshold region from real to complex spectra is
characterized by the breakdown of the Dyson maps or the metric operator. We
establish the explicit relationship to models currently under investigation in
the context of beam dynamics in optical lattices.Comment: 17 pages, 5 figure
Trace-anomaly driven inflation in $f(T)$ gravity and in minimal massive
  bigravity

We explore trace-anomaly driven inflation in modified gravity. It is
explicitly shown that in $T^2$ teleparallel gravity, the de Sitter inflation
can occur, although quasi de Sitter inflation happens in $R^2$ gravity.
Furthermore, we investigate the influence of the trace anomaly on inflation. It
is found that in $f(T)$ gravity, the de Sitter inflation can end because it
becomes unstable due to the trace anomaly, whereas also in higher derivative
gravity, the de Sitter inflation can be realized and it will be over thanks to
the trace anomaly for smaller parameter regions in comparison with those in
teleparallelism. The instability of the de Sitter inflation in $T^2$ gravity
and $R^2$ gravity (both with taking account of the trace anomaly) is examined.
In addition, we study trace-anomaly driven inflation in minimal massive
bigravity, where the contribution from the massive graviton acts as negative
cosmological constant. It is demonstrated that the de Sitter inflation can
occur and continue for long enough duration.Comment: 13 pages, no figure, version accepted for publication in Physics

On the structure of the transition disk around TW Hya

For over a decade, the structure of the inner cavity in the transition disk
of TW Hydrae has been a subject of debate. Modeling the disk with data obtained
at different wavelengths has led to a variety of proposed disk structures.
Rather than being inconsistent, the individual models might point to the
different faces of physical processes going on in disks, such as dust growth
and planet formation. Our aim is to investigate the structure of the transition
disk again and to find to what extent we can reconcile apparent model
differences. A large set of high-angular-resolution data was collected from
near-infrared to centimeter wavelengths. We investigated the existing disk
models and established a new self-consistent radiative-transfer model. A
genetic fitting algorithm was used to automatize the parameter fitting. Simple
disk models with a vertical inner rim and a radially homogeneous dust
composition from small to large grains cannot reproduce the combined data set.
Two modifications are applied to this simple disk model: (1) the inner rim is
smoothed by exponentially decreasing the surface density in the inner ~3 AU,
and (2) the largest grains (>100 um) are concentrated towards the inner disk
region. Both properties can be linked to fundamental processes that determine
the evolution of protoplanetary disks: the shaping by a possible companion and
the different regimes of dust-grain growth, respectively. The full
interferometric data set from near-infrared to centimeter wavelengths requires
a revision of existing models for the TW Hya disk. We present a new model that
incorporates the characteristic structures of previous models but deviates in
two key aspects: it does not have a sharp edge at 4 AU, and the surface density
of large grains differs from that of smaller grains. This is the first
successful radiative-transfer-based model for a full set of interferometric
data.Comment: 22 pages, 12 figures, accepted for publication in Astronomy &

The watering of tall trees - Embolization and recovery

We can propound a thermo-mechanical understanding of the ascent of sap to the
top of tall trees thanks to a comparison between experiments associated with
the cohesion-tension theory and the disjoining pressure concept for liquid
thin-films. When a segment of xylem is tight-filled with crude sap, the liquid
pressure can be negative although the pressure in embolized vessels remains
positive. Examples are given that illustrate how embolized vessels can be
refilled and why the ascent of sap is possible even in the tallest trees
avoiding the problem due to cavitation. However, the maximum height of trees is
limited by the stability domain of liquid thin-films.Comment: Extended introduction and additive comments removed from the Journal

CP, T and CPT versus temporal asymmetries for entangled states of the
  Bd-system

The observables used in the K-system to characterize T and CPT violation are
no longer useful for the Bd-system, since the width difference between the
physical states is vanishingly small. We show that only Im(epsilon) and
Re(delta) can survive if Delta Gamma=0, and build alternative CP-odd, CPT-odd,
T-odd and temporal asymmetries for the (B_CP -> B0, B0bar) transitions. These
quantities enable us to test T and CPT invariances of the effective Hamiltonian
for the B-system. The method needs the CP eigenstates B_CP, which can be tagged
unambiguously to order lambda^3 from the entangled states of a B-factory.Comment: 7 pages, no figure
Supersymmetry of RS bulk and brane

We review the construction of actions with supersymmetry on spaces with a domain wall. The latter objects act as sources inducing a jump in the gauge coupling constant. Despite these singularities, supersymmetry can be formulated, maintaining its role as a square root of translations in this singular space. The setup is designed for the application in five dimensions related to the Randall-Sundrum (RS) scenario. The space has two domain walls. We discuss the solutions of the theory with fixed scalars and full preserved supersymmetry, in which case one of the branes can be pushed to infinity, and solutions where half of the supersymmetries are preserved
