Model-Driven Development of Adaptable Service-Oriented Business Processes

Businesses typically structure their activities with workflows, which are often implemented in a rather static fashion in their IT systems.  Nowadays, system requirements change rapidly as businesses try to maintain their competitive edge, calling for similar agility of the IT systems.  To this end, we present STPOWLA, an approach that marries service oriented architecture, policies and workflows to support the agile execution of business workflows. In STPOWLA, the business is modelled by workflows, whose tasks are eventually carried out by services. Adapatation is obtained by allowing the stakeholders to define policies that establish the quality levels required of the services. The prototype STPOWLA support architecture comprizes the transformation of the workflow model into executable WS-BPEL to be deployed in the ODE-BPEL execution engine, the generation of default policies from the model, and the enactment of the policies by the APPEL policy server. The SENSORIA Finance Case Study is used throughout the paper.Peer-reviewedPost-prin
Quantification of patellar tendon reflex by motion analysis

This study collected quantitative measurements of the patellar tendon reflex using 3-dimensional motion analysis. The study was conducted in the Motion Analysis Laboratory, Faculty of Engineering, University of Malaya, Kuala Lumpur, Malaysia. Patellar tendon reflex of a group of healthy subjects involving 28 males and 22 females was examined. The left and right patellar tendons were tapped by a Queen Square reflex hammer with three different angles where the reflex hammer was released. The phenomenon of Jendrassik maneuver was tested by tapping on the tendon with the hammer raised to an angle of 60Â°. The purpose of this was to investigate the effect of reinforcement method on reflex responses. Results of the study showed that the patellar tendon reflex response of male subjects were higher at higher tapping force. Reflex response of the left and the right side did not show any significant difference. The study of tapping force on reflex response showed greater response at increasing tapping force. The reinforcement method named Jendrassik maneuver increased patellar tendon reflex response for both legs
Consistent Factorization of Jet Observables in Exclusive Multijet
  Cross-Sections

We demonstrate the consistency at the next-to-leading-logarithmic (NLL) level
of a factorization theorem based on Soft-Collinear Effective Theory (SCET) for
jet shapes in e+e- collisions. We consider measuring jet observables in
exclusive multijet final states defined with cone and k_T-type jet algorithms.
Consistency of the factorization theorem requires that the renormalization
group evolution of hard, jet, and soft functions is such that the physical
cross-section is independent of the factorization scale mu. The anomalous
dimensions of the various factorized pieces, however, depend on the color
representation of jets, choice of jet observable, the number of jets whose
shapes are measured, and the jet algorithm, making it highly nontrivial to
satisfy the consistency condition. We demonstrate the intricate cancellations
between anomalous dimensions that occur at the NLL level, so that, up to power
corrections that we identify, our factorization of the jet shape distributions
is consistent for any number of quark and gluon jets, for any number of jets
whose shapes are measured or unmeasured, for any angular size R of the jets,
and for any of the algorithms we consider. Corrections to these results are
suppressed by the SCET expansion parameter lambda (the ratio of soft to
collinear or collinear to hard scales) and in the jet separation measure 1/t^2
= tan^2(R/2)/tan^2(psi/2), where psi is the angular separation between jets.
Our results can be used to calculate a wide variety of jet observables in
multijet final states to NLL accuracy.Comment: 8 pages, 1 figure, uses elsarticle.cls; v2: minor edits, added

Density, structure and dynamics of water: the effect of Van der Waals
  interactions

It is known that ab initio molecular dynamics (AIMD) simulations of liquid
water, based on the generalized gradient approximation (GGA) to density
functional theory (DFT), yield structural and diffusive properties in
reasonable agreement with experiment only if artificially high temperatures are
used in the simulations. The equilibrium density, at normal conditions, of DFT
water has been recently shown by Schmidt et al. [J. Phys. chem. B, 113, 11959
(2009)] to be underestimated by different GGA functionals for exchange and
correlation, and corrected by the addition of interatomic pair potentials to
describe van derWaals (vdW) interactions. In this contribution we present a
DFTAIMD study of liquid water using several GGA functionals as well as the van
der Waals density functional (vdW-DF) of Dion et al. [Phys. Rev. Lett. 92,
246401(2004)]. As expected, we find that the density of water is grossly
underestimated by GGA functionals. When a vdW-DF is used, the density improves
drastically and the experimental diffusivity is reproduced without the need of
thermal corrections. We analyze the origin of the density differences between
all the functionals. We show that the vdW-DF increases the population of
non-H-bonded interstitial sites, at distances between the first and second
coordination shells. However, it excessively weakens the H-bond network,
collapsing the second coordination shell. This structural problem is partially
associated to the choice of GGA exchange in the vdW-DF. We show that a
different choice for the exchange functional is enough to achieve an overall
improvement both in structure and diffusivity.Comment: 11 pages, 9 figures, submitted. Revised versio
WINGS-SPE II: A catalog of stellar ages and star formation histories,
  stellar masses and dust extinction values for local clusters galaxies

The WIde-field Nearby Galaxy clusters Survey (WINGS) is a project whose
primary goal is to study the galaxy populations in clusters in the local
universe (z<0.07) and of the influence of environment on their stellar
populations. This survey has provided the astronomical community with a high
quality set of photometric and spectroscopic data for 77 and 48 nearby galaxy
clusters, respectively. In this paper we present the catalog containing the
properties of galaxies observed by the WINGS SPEctroscopic (WINGS-SPE) survey,
which were derived using stellar populations synthesis modelling approach. We
also check the consistency of our results with other data in the literature.
Using a spectrophotometric model that reproduces the main features of observed
spectra by summing the theoretical spectra of simple stellar populations of
different ages, we derive the stellar masses, star formation histories, average
age and dust attenuation of galaxies in our sample. ~5300 spectra were analyzed
with spectrophotometric techniques, and this allowed us to derive the star
formation history, stellar masses and ages, and extinction for the WINGS
spectroscopic sample that we present in this paper. The comparison with the
total mass values of the same galaxies derived by other authors based on SDSS
data, confirms the reliability of the adopted methods and data.Comment: 13 pages, 9 figures. Accepted for publication in Astronomy and

Estimation of latent variable models for ordinal data via fully
  exponential Laplace approximation

Latent variable models for ordinal data represent a useful tool in different
fields of research in which the constructs of interest are not directly
observable. In such models, problems related to the integration of the
likelihood function can arise since analytical solutions do not exist.
Numerical approximations, like the widely used Gauss Hermite (GH) quadrature,
are generally applied to solve these problems. However, GH becomes unfeasible
as the number of latent variables increases. Thus, alternative solutions have
to be found. In this paper, we propose an extended version of the Laplace
method for approximating the integrals, known as fully exponential Laplace
approximation. It is computational feasible also in presence of many latent
variables, and it is more accurate than the classical Laplace method
Contribution of asymmetric strange-antistrange sea to the
  Paschos-Wolfenstein relation

The NuTeV Collaboration reported a value of $\sin^{2}\theta_{w}$ measured in
neutrino-nucleon deep inelastic scattering, and found that the value is three
standard deviations from the standard model prediction. This result is obtained
under the assumption that the strange-antistrange sea quarks of nucleons are
symmetric, and that the up and down quark distributions are symmetric with the
simultaneous interchange of $u$$\leftrightarrow$$d$ and
$p$$\leftrightarrow$$n$. We discuss the contribution of asymmetric
strange-antistrange sea to the Paschos-Wolfenstein relation in the extraction
of weak mixing angle $\sin^{2}\theta_{w}$. We also point out that the
contribution of asymmetric strange-antistrange sea should remove roughly
30--80% of the discrepancy between the NuTeV result and other determinations of
$\sin^{2}\theta_{w}$, when using the light-cone meson-baryon model to calculate
the contribution of the strange-antistrange sea.Comment: 10 Latex pages, 2 figures, final versio
Distance and proper motion measurement of water masers in Shapless 269
  IRS 2w

We present astrometric analysis of archival data of water masers in the
star-forming region Sharpless 269 (S269) IRS 2w, observed with the VLBI
Exploration of Radio Astrometry. An annual parallax of one of the bright maser
features in this region was previously reported to be 0.189+/-0.008
milliarcsecond (mas) using part of the same archival data as we used. However,
we found that this maser feature is not the best to represent the annual
parallax to S269 IRS 2w because the morphology is remarkably elongated in the
east-west direction. For this study we have selected another maser feature
showing simpler morphology. This makes the new annual parallax estimate more
credible. Our newly obtained annual parallax is 0.247+/-0.034 mas,
corresponding to 4.05+0.65-0.49 kpc. This value is well consistent with the
3.7-3.8 kpc obtained using the kinematic distance estimates and photometric
distance modulus. We considered two hypotheses for the water maser spatial
distribution, a bipolar outflow and an expanding ring, in a kinematic model
fitting analysis with a radially expanding flow. At this stage, any conclusions
about the systemic proper motion could not be drawn from the kinematic
analysis. Alternatively, we evaluated the mean proper motion to be
(0.39+/-0.92, -1.27+/-0.90) mas/yr eastward and northward, respectively, from
the obtained proper motions of the detected water maser features. The newly
obtained annual parallax and mean proper motion give the peculiar motion of
S269 IRS 2w to be (Us, Vs, Ws) of (8+/-6, -21+/-17, 1+/-18) km/s.Comment: Astrophysical Journal, in pres
Precision Measurements of $A_1^n$ in the Deep Inelastic Regime

We have performed precision measurements of the double-spin virtual-photon
asymmetry $A_1$ on the neutron in the deep inelastic scattering regime, using
an open-geometry, large-acceptance spectrometer. Our data cover a wide
kinematic range $0.277 \leq x \leq 0.548$ at an average $Q^2$ value of
3.078~(GeV/c)$^2$, doubling the available high-precision neutron data in this
$x$ range. We have combined our results with world data on proton targets to
extract the ratio of polarized-to-unpolarized parton distribution functions for
up quarks and for down quarks in the same kinematic range. Our data are
consistent with a previous observation of an $A_1^n$ zero crossing near
$x=0.5$. We find no evidence of a transition to a positive slope in $(\Delta d
+ \Delta \bar{d})/(d + \bar{d})$ up to $x=0.548$.Comment: 6 pages, 2 figures, 3 tables. Reported results extended and slightly

CALIFA: a diameter-selected sample for an integral field spectroscopy
  galaxy survey

We describe and discuss the selection procedure and statistical properties of
the galaxy sample used by the Calar Alto Legacy Integral Field Area Survey
(CALIFA), a public legacy survey of 600 galaxies using integral field
spectroscopy. The CALIFA "mother sample" was selected from the Sloan Digital
Sky Survey (SDSS) DR7 photometric catalogue to include all galaxies with an
r-band isophotal major axis between 45" and 79.2" and with a redshift 0.005 < z
< 0.03. The mother sample contains 939 objects, 600 of which will be observed
in the course of the CALIFA survey. The selection of targets for observations
is based solely on visibility and thus keeps the statistical properties of the
mother sample. By comparison with a large set of SDSS galaxies, we find that
the CALIFA sample is representative of galaxies over a luminosity range of -19
> Mr > -23.1 and over a stellar mass range between 10^9.7 and 10^11.4Msun. In
particular, within these ranges, the diameter selection does not lead to any
significant bias against - or in favour of - intrinsically large or small
galaxies. Only below luminosities of Mr = -19 (or stellar masses < 10^9.7Msun)
is there a prevalence of galaxies with larger isophotal sizes, especially of
nearly edge-on late-type galaxies, but such galaxies form < 10% of the full
sample. We estimate volume-corrected distribution functions in luminosities and
sizes and show that these are statistically fully compatible with estimates
from the full SDSS when accounting for large-scale structure. We also present a
number of value-added quantities determined for the galaxies in the CALIFA
sample. We explore different ways of characterizing the environments of CALIFA
galaxies, finding that the sample covers environmental conditions from the
field to genuine clusters. We finally consider the expected incidence of active
galactic nuclei among CALIFA galaxies.Comment: 20 pages, 18 figures, A&A in pres
Cardy Formulae for SUSY Theories in d=4 and d=6

We consider supersymmetric theories on a space with compact space-like
slices. One can count BPS representations weighted by (-1)^F, or, equivalently,
study supersymmetric partition functions by compactifying the time direction. A
special case of this general construction corresponds to the counting of short
representations of the superconformal group. We show that in four-dimensional
N=1 theories the "high temperature" asymptotics of such counting problems is
fixed by the anomalies of the theory. Notably, the combination a-c of the trace
anomalies plays a crucial role. We also propose similar formulae for
six-dimensional (1,0) theories.Comment: 33 pages; added reference
Complete N=4 Structure of Low-Energy Effective Action in N=4 Super
  Yang-Mills Theories

Using the ${\cal N}=2$ superfield approach, we construct full ${\cal N}=4$
supersymmetric low-energy effective actions for ${\cal N}=4$ SYM models, with
both ${\cal N}=2$ gauge superfield strengths and hypermultiplet superfields
included. The basic idea is to complete the known non-holomorphic effective
potentials which depend only on ${\cal N}=2$ superfield strengths $W$ and
${\bar W}$ to the full on-shell ${\cal N}=4$ invariants by adding the
appropriate superfield hypermultiplet terms. We prove that the effective
potentials of the form ${ln} W {ln} \bar W$ can be ${\cal N} = 4$ completed in
this way and present the precise structure of the corresponding completions.
However, the effective potentials of the non-logarithmic form suggested in
hep-th/9811017 and hep-th/9909020 do not admit the ${\cal N}=4$ completion.
Therefore, such potentials cannot come out as (perturbative or
non-perturbative) quantum corrections in ${\cal N}=4$ SYM models.Comment: 14 pages, Latex, no figures, slight corrections, refs adde
Quantum parameter space in super Yang-Mills, II

In [1] (hep-th/0211069), the author has discussed the quantum parameter space
of the N=1 super Yang-Mills theory with one adjoint Higgs field Phi, tree-level
superpotential W_tree = m (Phi^2)/2 + g (Phi^3)/3$, and gauge group U(Nc). In
particular, full details were worked out for U(2) and U(3). By discussing
higher rank gauge groups like U(4), for which the classical parameter space has
a large number of disconnected components, we show that the phenomena discussed
in [1] are generic. It turns out that the quantum space is connected. The
classical components are related in the quantum theory either through standard
singularities with massless monopoles or by branch cuts without going through
any singularity. The branching points associated with the branch cuts
correspond to new strong coupling singularities, which are not associated with
vanishing cycles in the geometry, and at which glueballs can become massless.
The transitions discussed recently by Cachazo, Seiberg and Witten are special
instances of those phenomena.Comment: 12 pages including 2 large figure
The spectrum of multi-flavor $QCD_2$ and the non-Abelian Schwinger equation

Massless $QCD_2$ is dominated by classical configurations in the large $N_f$ limit. We use this observation to study the theory by finding solutions to equations of motion, which are the non-Abelian generalization of the Schwinger equation. We find that the spectrum consists of massive mesons with $M^2={e^2 N_f\over 2\pi}$ which correspond to Abelian solutions. We generalize previously discovered non-Abelian solutions and discuss their interpretation. We prove a no-go theorem ruling out the existence of soliton solutions. Thus the semi-classical approximation shows no baryons in the case of massless quarks, a result derived before in the strong-coupling limit only
T-duality for boundary-non-critical point-particle and string quantum mechanics

It is observed that some structures recently uncovered in the study of Calogero-Sutherland models and anyons are close analogs of well-known structures of boundary conformal field theory. These examples of ``boundary conformal quantum mechanics'', in spite of their apparent simplicity, have a rather reach structure, including some sort of T-duality, and could provide useful frameworks for testing general properties of boundary conformal theories. Of particular interest are the duality properties of anyons and Calogero-Sutherland particles in presence of boundary-violations of conformal invariance; these are here briefly analyzed leading to the conjecture of a general interconnection between (deformed) boundary conformal quantum mechanics, T-type duality, and (``exchange'' or ``exclusion'') exotic statistics. These results on the point-particle quantum-mechanics side are compared with recent results on the action of T-duality on open strings that satisfy conformal-invariance-violating boundary conditions. Moreover, it is observed that some of the special properties of anyon and Calogero-Sutherland quantum mechanics are also enjoyed by the M(atrix) quantum mechanics which has recently attracted considerable attention
The $K^{0}_{s}K^{0}_{s}$ Final State in Two-Photon Collisions and Some Implications for Glueball Searches

The K0sK0s final state in two-photon collisions is studied with the L3 detector at LEP using data at centre of mass energies from 91 GeV to 183 GeV. The K0sK0s mass spectrum is dominated by the formation of the f_2'(1525) tensor meson whose two-photon partial width is measured. Clear evidence for destructive f_2-a_2 interference is observed. No signal is present in the region around 2.2 GeV. An upper limit for the two-photon partial width times the K0sK0s branching ratio of the \xi(2230) glueball candidate is then derived. An enhancement is observed around 1750 MeV. It may be due to the formation of a radial recurrence of the f_2'(1525) or to the s\bar{s} member of the 0++ meson nonet
Towards a solution of pure Yang-Mills theory in 3+1 dimensions

We discuss an analytic approach towards the solution of pure Yang-Mills
theory in 3+1 dimensional spacetime. The approach is based on the use of local
gauge invariant variables in the Schr\"odinger representation and the large
$N$, planar limit. In particular, within this approach we point out unexpected
parallels between pure Yang-Mills theory in 2+1 and 3+1 dimensions. The most
important parallel shows up in the analysis of the ground state wave-functional
especially in view of the numerical similarity of the existing large N lattice
simulations of the spectra of 2+1 and 3+1 Yang Mills theories.Comment: 12 page
Physics of Strongly Coupled N=1 Supersymmetric SO(N_c) Gauge Theories

We construct an effective superpotential that describes dynamical flavor symmetry breaking in supersymmetric N=1 SO(N_c) theories with N_f-flavor quarks for N_f >= N_c. Our superpotential induces spontaneous flavor symmetry breaking of SU(N_f) down to SO(N_c)xSU(N_f-N_c) as nonabelian residual groups and respects the anomaly-matching property owing to the appearance of massless composite Nambu-Goldstone superfields. In massive SO(N_c) theories, our superpotential provides holomorphic decoupling property and consistent vacuum structure with instanton effect if N_c-2 quarks remain massless. This superpotential may reflect the remnant of physics corresponding to N=2 SO(N_c) theories near the Chebyshev point, which also exhibits dynamical flavor symmetry breaking
Representable E-theory for Co(X)-algebras

Let X be a locally compact space, and let A and B be Co(X)-algebras. We
define the notion of an asymptotic Co(X)-morphism from A to B and construct
representable E-theory groups RE(X;A,B). These are the universal groups on the
category of separable Co(X)-algebras that are Co(X)-stable,
Co(X)-homotopy-invariant, and half-exact. If A is RKK(X)-nuclear, these groups
are naturally isomorphic to Kasparov's representable KK-theory groups
RKK(X;A,B). Applications and examples are also discussed.Comment: For journal version, see

Efficient In Vivo Genome Editing Using RNA-Guided Nucleases

Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) systems have evolved in bacteria and archaea as a defense mechanism to silence foreign nucleic acids of viruses and plasmids. Recent work has shown that bacterial type II CRISPR systems can be adapted to create guide RNAs (gRNAs) capable of directing site-specific DNA cleavage by the Cas9 nuclease in vitro. Here we show that this system can function in vivo to induce targeted genetic modifications in zebrafish embryos with efficiencies comparable to those obtained using ZFNs and TALENs for the same genes. RNA-guided nucleases robustly enabled genome editing at 9 of 11 different sites tested, including two for which TALENs previously failed to induce alterations. These results demonstrate that programmable CRISPR/Cas systems provide a simple, rapid, and highly scalable method for altering genes in vivo, opening the door to using RNA-guided nucleases for genome editing in a wide range of organisms
