Factorization of the soft gluon divergence from the dipole picture deep inelastic scattering cross sections at next-to-leading order

2018

We use a factorization scheme analogous to one proposed for single inclusive forward hadron production to factorize the soft gluon divergence present in the deep inelastic scattering cross sections in the dipole picture at next-to-leading order (NLO). We show numerically that in this carefully constructed scheme it is possible to obtain meaningful results for the DIS cross sections at NLO, and so we are able to quantitatively study the recently derived NLO corrections to the DIS cross sections. We find that the NLO corrections can be significant and sensitive to the details of the factorization scheme used for the resummation of the large logarithms into the BK evolution equation. In the ca…

Axion cold dark matter: Status after Planck and BICEP2

2014

We investigate the axion dark matter scenario (ADM), in which axions account for all of the dark matter in the Universe, in light of the most recent cosmological data. In particular, we use the Planck temperature data, complemented by WMAP E-polarization measurements, as well as the recent BICEP2 observations of B-modes. Baryon Acoustic Oscillation data, including those from the Baryon Oscillation Spectroscopic Survey, are also considered in the numerical analyses. We find that, in the minimal ADM scenario, the full dataset implies that the axion mass m_a = 82.2 pm 1.1 {\mu}eV (corresponding to the Peccei-Quinn symmetry being broken at a scale f_a = (7.54 pm 0.10)*10^10 GeV), or m_a = 76.6 …

Non-linear systems under Levy White Noise Handled by path integration method

2009

Aim of this paper is an investigation on the consistency of the Path Integration (PI) method already proposed by Naess & Johansen, 1991,1993 for non-linear systems driven by α-stable white noise. It is shown that in the limit, as τ→0, the Einstein-Smoluchowsky (ES) equation is fully restored. Once the consistency of the PI is demonstrated for the half oscillator, then the extension of the ES equation for MDOF system is found starting from the PI method.

In vivo optical coherence tomography imaging in a case of mucous membrane pemphigoid and a negative Nikolsky's sign.

2017

There is currently a growing interest in new diagnostic tools of the oral cavity and mucosa which are non-invasive, repeatable and reliable. A diagnosis of a suspected, autoimmune pathology was made regarding a 57-year-old patient with desquamative gingivitis. However, a negative Nikolsky's sign did not seem to indicate a diagnosis of mucous membrane pemphigoid neither was there any indication as to the optimum location for an incisional biopsy. As an imaging method, the use of optical coherence tomography (OCT) has enabled the obtaining of tomographic (cross-sectional) scans of tissue. Such images are acquired prior to and after verifying Nikolsky's sign, thereby enabling the clinician to …

Paul Rudolph. Bond Centre

2015

Il Bond Centre di Paul Rudolph ad Hong Kong è un complesso di due torri gemelle connesse con un grande basamento. E' particolarmente interessante per il modo in cui articola lo spazio urbano dell'attacco a terra. Esso rivela la concezione di Rudolph dell'edificio alto costituito una parte urbana sottostante (village in the city). Esso viene comparato ad altri progetti di Rudolph ed alle teorie di Rem Koolhaas sugli edifici alti. The Bond Centre is one of the first big skyscrapers in Hong Kong. It is actually a twin towers complex very peculiar in the manner it relates to the urban space of the city. It unfolds Rudolph's ideas about the tall buildings and their link to the city. The author r…

The ARGO-YBJ Experiment Progresses and Future Extension

2010

Gamma ray source detection above 30 TeV is an encouraging approach for finding galactic cosmic ray origins. All sky survey for gamma ray sources using wide field of view detector is essential for population accumulation for various types of sources above 100 GeV. To target the goals, the ARGO-YBJ experiment has been established. Significant progresses have been made in the experiment. A large air shower detector array in an area of 1 km2 is proposed to boost the sensitivity. Hybrid detections with multi-techniques will allow a good discrimination between different types of primary particles, including photons and protons, thus enable an energy spectrum measurement for individual species. F…

Isolated photon production in proton-nucleus collisions at forward rapidity

2018

We calculate isolated photon production at forward rapidities in proton-nucleus collisions in the Color Glass Condensate framework. Our calculation uses dipole cross sections solved from the running coupling Balitsky-Kovchegov equation with an initial condition fit to deep inelastic scattering data. For comparison, we also update the results for the nuclear modification factor for pion production in the same kinematics. We present predictions for future forward RHIC and LHC measurements at $\sqrt{s_{NN}}=200$ GeV and $\sqrt{s_{NN}}=8$ TeV.

Predicting ACL Injury Using Machine Learning on Data From an Extensive Screening Test Battery of 880 Female Elite Athletes

2022

Background: Injury risk prediction is an emerging field in which more research is needed to recognize the best practices for accurate injury risk assessment. Important issues related to predictive machine learning need to be considered, for example, to avoid overinterpreting the observed prediction performance. Purpose: To carefully investigate the predictive potential of multiple predictive machine learning methods on a large set of risk factor data for anterior cruciate ligament (ACL) injury; the proposed approach takes into account the effect of chance and random variations in prediction performance. Study Design: Case-control study; Level of evidence, 3. Methods: The authors used 3-dime…

Palladium local structure of La1-xSrxCo1-yFey-0.03Pd0.03O3-δperovskites synthesized using a one pot citrate method

2014

Nanostructured La1-xSrxCo1-yFey-0.03Pd0.03O3-δ(LSCF-Pd) perovskites with fixed La-Sr composition (x = 0.4) and two different Fe contents (y = 0.2 and 0.8) were successfully synthesized using a one pot citrate method starting from nitrates of the metal cations. Pd-free La1-xSrxCo1-yFeyO3-δ(LSCF) systems were prepared for comparison. LSCF powders were calcined at 1300 °C and characterized by XRD and Rietveld refinement, EXAFS, XPS, TPR analyses. Promotion of La0.6Sr0.4Co0.8Fe0.2O3-δand of La0.6Sr0.4Co0.2Fe0.8O3-δby incorporation of palladium was evidenced by solving the local environment of Pd using EXAFS spectroscopy. XPS analyses, in agreement with TPR measurements, demonstrated an inc…
