ITACA (ITalian ACcelerometric Archive): a Web Portal for the Dissemination of the Italian Strong Motion Data

The Italian strong-motion database contains 2182 three component waveforms generated by 1004 earthquakes with a maximum magnitude of 6.9 (1980 Irpinia earthquake) covering the period range from 1972 to 2004. The database is devoted to serving the seismological and engineering communities.
The database can be accessed on-line at the site http://itaca.mi.ingv.it, where a wide range of search tools enables the user to interactively search events, recording stations and retrieve waveforms with particular characteristics, whose parameters can be specified, as needed, through a graphical user interface. A range of display options allows users to view data in different contexts, extract and download time series and spectral data.
The database was created during a joint project between Istituto Nazionale di Geofisica e Vulcanologia (INGV, Italian institute for geophysics and vulcanology) and Dipartimento della Protezione Civile (DPC, Italian civil protection). The aim of the project was the collection, homogenization and distribution of data acquired over the time period 1972-2004 in Italy by different Italian institutions, namely Ente Nazionale per l’Energia Elettrica (ENEL, Italian electricity company), Ente per le Nuove tecnologie, l’Energia e l’Ambiente (ENEA, Italian energy and environment organization) and DPC. The project had multiple purposes, such as permanent strong motion monitoring and temporary monitoring during seismic sequences or before permanent installation. 
This database brings up to date the ENEA strong motion data collection which ended in 1993 and the European database where the most recent Italian data pertain to the Umbria-Marche sequence of 1997-1998 (Ambraseys at al., 2002). In addition effort was spent reviewing strong motion metadata and data processing to increase data quality and reliability. 
This article describes the steps that led to the completion of the project and provides an overview of the search capabilities available at the database interface website
The ionospheric response during an interval of Pc5 ULF wave activity

A preliminary analysis of Pc5, ULF wave activity observed with the IMAGE magnetometer array and the EISCAT UHF radar in the post midnight sector indicates that such waves can be caused by the modulation of the ionospheric conductivity as well as the wave electric field. An observed Pc5 pulsation is divided into three separate intervals based upon the EISCAT data. In the first and third, the Pc5 waves are observed only in the measured electron density between 90 and 112 km and maxima in the electron density at these altitudes are attributed to pulsed precipitation of electrons with energies up to 40 keV which result in the height integrated Hall conductivity being pulsed between 10 and 50 S. In the second interval, the Pc5 wave is observed in the F-region ion temperature, electron density and electron temperature but not in the D and E region electron densities. The analysis suggests that the wave during this interval is a coupled Alfven and compressional mode.4226
First Results on Applying a non-linear Effect Formalism to Alliances between Political Parties and Buy and Sell Dynamics.

12 month embargo from first publication.We discuss a non linear extension of a model of alliances in politics, recently proposed by one of us. The model is constructed in terms of operators, describing the interest of three parties to form, or not, some political alliance with the other parties. The time evolution of what we call the decision functions is deduced by introducing a suitable Hamiltonian, which describes the main effects of the interactions of the parties amongst themselves and with their environments, which are generated by their electors and by people who still have no clear idea for which party to vote (or even if to vote). The Hamiltonian contains some non-linear effects, which takes into account the role of a party in the decision process of the other two parties.\ud

Moreover, we show how the same Hamiltonian can also be used to construct a formal structure which can describe the dynamics of buying and selling financial assets (without however implying a specific price setting mechanism).Peer-reviewedPost-prin
QED as the tensionless limit of the spinning string with contact interaction.

QED with spinor matter is argued to correspond to the tensionless limit of spinning strings with contact interactions. The strings represent electric lines of force with charges at their ends. The interaction is constructed from a delta-function on the world-sheet which, although off-shell, decouples from the world-sheet metric. Integrating out the string degrees of freedom with fixed boundary generates the super-Wilson loop that couples spinor matter to electromagnetism in the world-line formalism. World-sheet and world-line, but not spacetime, supersymmetry underpin the model
A comparison of local phosphorescence detection and fluid dynamic gauging methods for studying the removal of cohesive fouling layers: effect of layer roughness

The performance of industrial cleaning in place (CIP) procedures is critically important for food manufacture.  CIP has yet to be optimised for many processes, in part since the mechanisms involved in cleaning are not fully understood.  Laboratory tests have an important role in guiding industrial trials, and this paper introduces and compares two experimental techniques developed for studying CIP mechanisms: local phosphorescence detection (LPD), and scanning fluid dynamic gauging (sFDG).  To illustrate the comparison, each technique is used to investigate the influence of soil topology on the cleaning of pre-gelatinised starch-based layers from 316 stainless steel substrates by aqueous NaOH solutions at ambient temperature.  The roughness of the soil surface is varied by incorporating zinc sulphide particles with different particle size distributions (range 1 - 80 μm) into the starch suspensions.  The soil roughness increased with the use of larger particles, increasing the 3D arithmetic mean roughness (Sa) of the dry layers (range 0.37 - 3.33 μm).  Rough layers were cleaned more readily than those containing small inclusions, with a good correlation between the cleaning rates observed during LPD and FDG measurements.  The LPD technique, which is an instrumented CIP test, gives a better indication of the cleaning time, while sFDG measurements provide further insight into the removal mechanisms.NOTICE: this is the author's version of a work that was accepted for publication in Food Bioproducts Processing.

Boltzmann-conserving classical dynamics in quantum time-correlation functions: “Matsubara dynamics”

We show that a single change in the derivation of the linearized semiclassical-initial value representation (LSC-IVR or “classical Wigner approximation”) results in a classical dynamics which conserves the quantum Boltzmann distribution. We rederive the (standard) LSC-IVR approach by writing the (exact) quantum time-correlation function in terms of the normal modes of a free ring-polymer (i.e., a discrete imaginary-time Feynman path), taking the limit that the number of polymer beads N → ∞, such that the lowest normal-mode frequencies take their “Matsubara” values. The change we propose is to truncate the quantum Liouvillian, not explicitly in powers of ħ2 at ħ0 (which gives back the standard LSC-IVR approximation), but in the normal-mode derivatives corresponding to the lowest Matsubara frequencies. The resulting “Matsubara” dynamics is inherently classical (since all terms O(ħ2) disappear from the Matsubara Liouvillian in the limit N → ∞) and conserves the quantum Boltzmann distribution because the Matsubara Hamiltonian is symmetric with respect to imaginary-time translation. Numerical tests show that the Matsubara approximation to the quantum time-correlation function converges with respect to the number of modes and gives better agreement than LSC-IVR with the exact quantum result. Matsubara dynamics is too computationally expensive to be applied to complex systems, but its further approximation may lead to practical methods.T.J.H.H., M.J.W., and S.C.A. acknowledge funding from the U.K. Engineering and Physical Sciences Research Council.

Physics of neutrino flavor transformation through matter-neutrino
  resonances

In astrophysical environments such as core-collapse supernovae and neutron
star-neutron star or neutron star-black hole mergers where dense neutrino media
are present, matter-neutrino resonances (MNRs) can occur when the neutrino
propagation potentials due to neutrino-electron and neutrino-neutrino forward
scattering nearly cancel each other. We show that neutrino flavor
transformation through MNRs can be explained by multiple adiabatic solutions
similar to the Mikheyev-Smirnov-Wolfenstein mechanism. We find that for the
normal neutrino mass hierarchy, neutrino flavor evolution through MNRs can be
sensitive to the shape of neutrino spectra and the adiabaticity of the system,
but such sensitivity is absent for the inverted hierarchy.Comment: 7 pages, 4 figure
Yang-Baxter invariance of the Nappi-Witten model

We study Yang-Baxter deformations of the Nappi-Witten model with a
prescription invented by Delduc, Magro and Vicedo. The deformations are
specified by skew-symmetric classical $r$-matrices satisfying (modified)
classical Yang-Baxter equations. We show that the sigma-model metric is
invariant under arbitrary deformations (while the coefficient of $B$-field is
changed) by utilizing the most general classical $r$-matrix. Furthermore, the
coefficient of $B$-field is determined to be the original value from the
requirement that the one-loop $\beta$-function should vanish. After all, the
Nappi-Witten model is the unique conformal theory within the class of the
Yang-Baxter deformations preserving the conformal invariance.Comment: 12 pages, v2: typos corrected and clarifications added, v3:

Five transiting hot Jupiters discovered using WASP-South, Euler and
  TRAPPIST: WASP-119 b, WASP-124 b, WASP-126 b, WASP-129 b and WASP-133 b

We have used photometry from the WASP-South instrument to identify 5 stars
showing planet-like transits in their light curves. The planetary nature of the
companions to these stars has been confirmed using photometry from the EulerCam
instrument on the Swiss Euler 1.2-m telescope and the TRAPPIST telescope, and
spectroscopy obtained with the CORALIE spectrograph. The planets discovered are
hot Jupiter systems with orbital periods in the range 2.17 to 5.75 days, masses
from 0.3M$_{\rm Jup}$ to 1.2M$_{\rm Jup}$ and with radii from 1R$_{\rm Jup}$ to
1.5R$_{\rm Jup}$. These planets orbit bright stars (V = 11-13) with spectral
types in the range F9 to G4. WASP-126 is the brightest planetary system in this
sample and hosts a low-mass planet with a large radius (0.3 M$_{\rm Jup}$ ,
0.95R$_{\rm Jup}$), making it a good target for transmission spectroscopy. The
high density of WASP-129 A suggests that it is a helium-rich star similar to
HAT-P-11 A. WASP-133 has an enhanced surface lithium abundance compared to
other old G-type stars, particularly other planet host stars. These planetary
systems are good targets for follow-up observations with ground-based and
space-based facilities to study their atmospheric and dynamical properties.Comment: 8 pages, 6 figures. Accepted for publication in A&
Dark Matter and Leptogenesis Linked by Classical Scale Invariance

In this work we study a classically scale invariant extension of the Standard
Model that can explain simultaneously dark matter and the baryon asymmetry in
the universe. In our set-up we introduce a dark sector, namely a non-Abelian
SU(2) hidden sector coupled to the SM via the Higgs portal, and a singlet
sector responsible for generating Majorana masses for three right-handed
sterile neutrinos. The gauge bosons of the dark sector are mass-degenerate and
stable, and this makes them suitable as dark matter candidates. Our model also
accounts for the matter-anti-matter asymmetry. The lepton flavour asymmetry is
produced during CP-violating oscillations of the GeV-scale right-handed
neutrinos, and converted to the baryon asymmetry by the electroweak sphalerons.
All the characteristic scales in the model: the electro-weak, dark matter and
the leptogenesis/neutrino mass scales, are generated radiatively, have a common
origin and related to each other via scalar field couplings in perturbation
theory.Comment: 23 pages, 10 figures, v2: matches the version to appear in JHE
Higher spin super-Cotton tensors and generalisations of the
  linear-chiral duality in three dimensions

In three spacetime dimensions, (super)conformal geometry is controlled by the
(super) Cotton tensor. We present a new duality transformation for N-extended
supersymmetric theories formulated in terms of the linearised super-Cotton
tensor or its higher spin extensions for the cases N=2, 1, 0. In the N=2 case,
this transformation is a generalisation of the linear-chiral duality, which is
known to provide a dual description in terms of chiral superfields for general
models of self-interacting N=2 vector multiplets in three dimensions and N=1
tensor multiplets in four dimensions. For superspin-1 (gravitino multiplet),
superspin-3/2 (supergravity multiplet) and higher superspins s>3/2, the duality
transformation relates a higher-derivative theory to one containing at most two
derivatives at the component level. In the N=1 case, we introduce gauge
prepotentials for higher spin superconformal gravity and construct the
corresponding super-Cotton tensors, as well as the higher spin extensions of
the linearised N=1 conformal supergravity action. Our N=1 duality
transformation is a higher spin extension of the known superfield duality
relating the massless N=1 vector and scalar multiplets. In the
non-supersymmetric (N=0) case, the gauge prepotentials for higher spin
conformal geometry (both bosonic and fermionic) and the corresponding Cotton
tensors can be obtained from their N=1 counterparts by carrying out N=1 --> N=0
reduction. In the bosonic sector, this reduction is shown to lead to the Cotton
tensors for higher spins constructed by Pope and Townsend, and by Damour and
Deser in the spin-3 case. Our N=0 duality transformation is a higher spin
extension of the vector-scalar duality.Comment: 13 pages; V2: title and abstract modified, references and comments

Isolation of underivatized amino acids by ion-pair high performance liquid chromatography for precise measurement of nitrogen isotopic composition of amino acids: development of comprehensive LC x GC/C/IRMS method

Nitrogen isotopic composition of amino acids has been widely applied to biochemical, ecological, archaeological, and biogeochemical studies in an attempt to trace nitrogen source and transformation processes. For accurate isotope analysis of individual amino acids, we validated a preparative method involving the isolation of underivatized amino acids by ion-pair chromatographic separation and confirmed the consistency of nitrogen isotope composition. Ion-pair reversed-phase liquid chromatography coupled with electrospray ionization mass spectrometry (LC/ESI-MS) and gas chromatography/ combustion coupled with isotope ratio mass spectrometry (GC/C/IRMS) were conducted for the purpose of separation of underivatized amino acids and nitrogen isotopic analysis, respectively. Firstly, we confirmed the resolution of proteinogenic and non-proteinogenic amino acids by the preparative ion-pair LC separation. Diagnostic product ions determined by mass spectrometry can support the rapid identification of individual amino acids in screening analyses. Secondly, we observed no dependency on nitrogen isotopic composition for the injection amount of underivatized amino acids and even for different chemical formula including neutral, acidic, sulfur-containing, heterocyclic, and aromatic species. The recovery during the LC was 91.7 ± 4.3% (n=3). The present method and strategy of LC coupled with GC/C/IRMS (i.e., comprehensive LC x GC/C/IRMS) are useful for the high precision determination of the nitrogen isotopic composition of amino acids, in conjunction with an appropriate pre-treatment of cation-exchange chromatographic procedures.CC BY 3.
DC-SCRIPT is a novel regulator of the tumor suppressor gene CDKN2B and induces cell cycle arrest in ERα-positive breast cancer cells

Breast cancer is one of the most common causes of cancer-related deaths in women. The estrogen receptor (ERα) is well known for having growth promoting effects in breast cancer. Recently, we have identified DC-SCRIPT (ZNF366) as a co-suppressor of ERα and as a strong and independent prognostic marker in ESR1 (ERα gene)-positive breast cancer patients. In this study, we further investigated the molecular mechanism on how DC-SCRIPT inhibits breast cancer cell growth. DC-SCRIPT mRNA levels from 190 primary ESR1-positive breast tumors were related to global gene expression, followed by gene ontology and pathway analysis. The effect of DC-SCRIPT on breast cancer cell growth and cell cycle arrest was investigated using novel DC-SCRIPT-inducible MCF7 breast cancer cell lines. Genome-wide expression profiling of DC-SCRIPT-expressing MCF7 cells was performed to investigate the effect of DC-SCRIPT on cell cycle-related gene expression. Findings were validated by real-time PCR in a cohort of 1,132 ESR1-positive breast cancer patients. In the primary ESR1-positive breast tumors, DC-SCRIPT expression negatively correlated with several cell cycle gene ontologies and pathways. DC-SCRIPT expression strongly reduced breast cancer cell growth in vitro, breast tumor growth in vivo, and induced cell cycle arrest. In addition, in the presence of DC-SCRIPT, multiple cell cycles related genes were differentially expressed including the tumor suppressor gene CDKN2B. Moreover, in 1,132 primary ESR1-positive breast tumors, DC-SCRIPT expression also correlated with CDKN2B expression. Collectively, these data show that DC-SCRIPT acts as a novel regulator of CDKN2B and induces cell cycle arrest in ESR1-positive breast cancer cells
Gender Systems and Women's Labor Force Participation in the Salmon Industry in Chiloe, Chile

Contains fulltext :
                  142407.pdf (publisher's version ) (Open Access)This paper, which follows the emergence of the salmon industry in the 1990s in Chiloe, Chile, demonstrates that factors restricting women's participation in labor force and wage differences between women and men are related to the gender systems operating in Chiloe. Results indicate that these systems reflect the territory's demographic and agrarian history and that local gender systems have a positive influence on women's participation in the labor market, though this is not accompanied by decreased salary discrimination in the salmon industry. The implication is that territory-specific and gender factors must be considered in national employment policie
A radiotracer study of the adsorption behavior of aqueous Ba2+ ions on nanoparticles of zero-valent iron

Recently, iron nanoparticles are increasingly being tested as adsorbents for various types of organic and inorganic pollutants. In this study, nanoparticles of zero-valent iron (NZVI) synthesized under atmospheric conditions were employed for the removal of Ba2+ ions in a concentration range 10-3 to 10-6 M. Throughout the study, 133Ba was used as a tracer to study the effects of time, concentration, and temperature. The obtained data was analyzed using various kinetic models and adsorption isotherms. Pseudo-second-order kinetics and Dubinin-Radushkevich isotherm model provided the best correlation with the obtained data. Observed thermodynamic parameters showed that the process is exothermic and hence enthalpy-driven.2006 İYTE 1
Search for pair-produced long-lived neutral particles decaying to jets in the ATLAS hadronic calorimeter in pp collisions at root s=8 Tev

Çetin, Serkant Ali (Dogus Author)The ATLAS detector at the Large Hadron Collider at CERN is used to search for the decay of a scalar boson to a pair of long-lived particles, neutral under the Standard Model gauge group, in 20.3 fb(-1) of data collected in proton-proton collisions at root s = 8 TeV. This search is sensitive to long-lived particles that decay to Standard Model particles producing jets at the outer edge of the ATLAS electromagnetic calorimeter or inside the hadronic calorimeter. No significant excess of events is observed. Limits are reported on the product of the scalar boson production cross section times branching ratio into long-lived neutral particles as a function of the proper lifetime of the particles. Limits are reported for boson masses from 100 GeV to 900 GeV, and a long-lived neutral particle mass from 10 GeV to 150 GeV
Acid/Base-Triggered Switching of Circularly Polarized Luminescence and Electronic Circular Dichroism in Organic and Organometallic Helicenes

International audienceElectronic circular dichroism and circularly polarized luminescence acid/base switching activity has been demonstrated in helicene-bipyridine proligand 1 a and in its “rollover” cycloplatinated derivative 2 a. Whereas proligand 1 a displays a strong bathochromic shift (>160 nm) of the nonpolarized and circularly polarized luminescence upon protonation, complex 2 a displays slightly stronger emission. This strikingly different behavior between singlet emission in the organic helicene and triplet emission in the organometallic derivative has been rationalized by using quantum-chemical calculations. The very large bathochromic shift of the emission observed upon protonation of azahelicene-bipyridine 1 a has been attributed to the decrease in aromaticity (promoting a charge-transfer-type transition rather than a π–π* transition) as well as an increase in the HOMO–LUMO character of the transition and stabilization of the LUMO level upon protonation
Networks of silicon nanowires: A large-sclae atomistic electronic structure analysis

Cataloged from PDF version of article.Networks of silicon nanowires possess intriguing electronic properties surpassing the predictions based on quantum confinement of individual nanowires. Employing large-scale atomistic pseudopotential computations, as yet unexplored branched nanostructures are investigated in the subsystem level as well as in full assembly. The end product is a simple but versatile expression for the bandgap and band edge alignments of multiply-crossing Si nanowires for various diameters, number of crossings, and wire orientations. Further progress along this line can potentially topple the bottom-up approach for Si nanowire networks to a top-down design by starting with functionality and leading to an enabling structure. © 2013 AIP Publishing LLC
