Low rank Runge-Kutta methods, symplecticity and stochastic Hamiltonian problems with additive noise

Full-text article is free to read on the publisher website.\ud
\ud
In this paper we extend the ideas of Brugnano, Iavernaro and Trigiante in their development of HBVM($s,r$) methods to construct symplectic Runge-Kutta methods for all values of $s$ and $r$ with $s\geq r$. However, these methods do not see the dramatic performance improvement that HBVMs can attain.  Nevertheless, in the case of additive stochastic Hamiltonian problems an extension of these ideas, which requires the simulation of an independent Wiener process at each stage of a Runge-Kutta method, leads to methods that have very favourable properties. These ideas are illustrated by some simple numerical tests for the modified midpoint rule
Re-examining the evidence in radiation dermatitis management literature : an overview and a critical appraisal of systematic reviews

Purpose: \ud
\ud
To provide an overview and a critical appraisal of systematic reviews (SRs) of published interventions for the prevention/management of radiation dermatitis.\ud
\ud
Methods and Materials: \ud
\ud
We searched Medline, CINAHL, Embase, and the Cochrane Library.  We also manually searched through individual reference lists of potentially eligible articles and a number of key journals in the topic area. Two authors screened all potential articles and included eligible SRs. Two authors critically appraised and extracted key findings from the included reviews using AMSTAR (the measurement tool for “assessment of multiple systematic reviews”).\ud
\ud
Results: \ud
\ud
Of 1837 potential titles, 6 SRs were included. A number of interventions have been reported to be potentially beneficial for managing radiation dermatitis. Interventions evaluated in these reviews included skin care advice, steroidal/nonsteroidal topical agents, systemic therapies, modes of radiation delivery, and dressings. However, all the included SRs reported that there is insufficient evidence supporting any single effective intervention. The methodological quality of the included studies varied, and methodological shortfalls in these reviews might create biases to the overall results or recommendations for clinical practice.\ud
\ud
Conclusions: \ud
\ud
An up-to-date high-quality SR in the prevention/management of radiation dermatitis is needed to guide practice and direction for future research. We recommend that clinicians or guideline developers critically evaluate the information of SRs in their decision making
Utilizing interactive multimedia for the empowerment of aboriginal health workers

This paper reports on a study that was based on the expectation that using interactive multimedia technology to develop an up-to-date education program for Aboriginal health workers has the potential to expand and reinforce their professional skills throughout their careers. It could maintain and improve their capabilities, improve the quality of healthcare delivery and overall health outcomes for their patients; empower them by being self independent learning, build up self-confidence by allowing them to apply this new learning technology in their work. This article first looks at the Aboriginal health gaps, then explains the approach and findings.  Then through a qualitative semi-structure open ended interview as a general need assessment for Interactive multimedia program development, it explores the factors affecting Aboriginal health workers' ability to have more control over their continuing education and being self–esteem and confidence.
Innovating like China: a theory of stage-dependent intellectual property rights

Inspired by the Chinese experience, we develop a Schumpeterian growth model of distance to frontier in which economic growth in the developing country is driven by
domestic innovation as well as imitation and transfer of foreign technologies through foreign direct investment. We show that optimal intellectual property rights (IPR)
protection is stage-dependent. At an early stage of development, the country implements weak IPR protection to facilitate imitation. At a later stage of development, the
country implements strong IPR protection to encourage domestic innovation. We also calibrate the model to aggregate data of the Chinese economy to simulate the optimal
path of patent strength, which is increasing as the country evolves towards the world technology frontier, and this dynamic pattern is consistent with the actual evolution of
the patent system in China. Furthermore, we use a dynamic panel regression model to provide empirical evidence that supports the key implication of our theoretical model.
Search for direct slepton and gaugino production in final states with two leptons and missing transverse momentum with the ATLAS detector in pp collisions at root s = 7 TeV

ATLAS Collaboration Contributor: Paul Douglas Jackson and Nitesh Soni of School of Chemistry and Physics, University of Adelaide, Adelaide, Australia.A search for the electroweak pair production of charged sleptons and weak gauginos decaying into final states with two leptons is performed using 4.7 fb⁻¹ of proton–proton collision data at √s = 7 TeV recorded with the ATLAS experiment at the Large Hadron Collider. No significant excesses are observed with respect to the prediction from Standard Model processes. In the scenario of direct slepton production, if the sleptons decay directly into the lightest neutralino, left-handed slepton masses between 85 and 195 GeV are excluded at 95% confidence level for a 20 GeV neutralino. Chargino masses between 110 and 340 GeV are excluded in the scenario of direct production of wino-like chargino pairs decaying into the lightest neutralino via an intermediate on-shell charged slepton for a 10 GeV neutralino. The results are also interpreted in the framework of the phenomenological minimal supersymmetric Standard Model.ATLAS Collaboratio
Phenotypic Association Analyses With Copy Number Variation in Recurrent Depressive Disorder.

BACKGROUND: Defining the molecular genomic basis of the likelihood of developing depressive disorder is a considerable challenge. We previously associated rare, exonic deletion copy number variants (CNV) with recurrent depressive disorder (RDD). Sex chromosome abnormalities also have been observed to co-occur with RDD.
METHODS: In this reanalysis of our RDD dataset (N = 3106 cases; 459 screened control samples and 2699 population control samples), we further investigated the role of larger CNVs and chromosomal abnormalities in RDD and performed association analyses with clinical data derived from this dataset.
RESULTS: We found an enrichment of Turner's syndrome among cases of depression compared with the frequency observed in a large population sample (N = 34,910) of live-born infants collected in Denmark (two-sided p = .023, odds ratio = 7.76 [95% confidence interval = 1.79-33.6]), a case of diploid/triploid mosaicism, and several cases of uniparental isodisomy. In contrast to our previous analysis, large deletion CNVs were no more frequent in cases than control samples, although deletion CNVs in cases contained more genes than control samples (two-sided p = .0002).
CONCLUSIONS: After statistical correction for multiple comparisons, our data do not support a substantial role for CNVs in RDD, although (as has been observed in similar samples) occasional cases may harbor large variants with etiological significance. Genetic pleiotropy and sample heterogeneity suggest that very large sample sizes are required to study conclusively the role of genetic variation in mood disorders
And then came Complex Project Management

The subject of management is renowned for its addiction to fads and fashions.
Project Management is no exception. The issue of interest for this paper is the
establishment of standards in the area, specifically the ‘College of Complex
Project Managers’ and their ‘competency standard for complex project managers’.
Both the college and the standard have generated significant interest in the
Project Management community. Whilst the need for development of the means to
manage complex projects is acknowledged, a critical evaluation show significant
flaws in the definition of complex in this case, the process by which the
College and its standard have emerged, and the content of the standard. If
Project Management is to continue to develop as a profession, it will need an
evidence-based approach to the generation of knowledge and standards. The issues
raised by the evaluation provide the case for a portfolio of research that
extends the existing bodies of knowledge into large-scale complicated (or major)
projects. We propose that it would be owned by the practitioner community,
rather than focused on one organization. Research questions are proposed that
would commence this stream of activity towards an intelligent synthesis of what
is required to manage in both complicated and truly complex environments. This
is a revised paper previously presented at the 21st IPMA World Congress on

Thermoreversible behavior of κ-carrageenan and its apatite-forming ability in simulated body fluid

Osteoconductive materials with self-setting ability have received much attention because their properties allow developing injectable materials for bone defects. Thermosensitive hydrogel with ability of bone-like apatite formation in a body environment is a candidate of injectable bone fillers with osteoconductivity because the apatite formation on materials is an essential to show osteoconduction. The present study focused on the development of a thermosensitive hydrogel through modifications of the sulphonic groups of the polysaccharide, κ-carrageenan, with potassium chloride (KCl) and calcium chloride (CaCl2). We found that the gelation temperature of κ-carrageenan solutions increased with increasing amounts of K+ ions. Apatite formation was observed on the gel after exposure to simulated body fluid for 0.5 day when the gel was prepared with a molar ratio of Ca2+/sulfonic groups = 1.5. These results indicate that a thermosensitive κ-carrageenan hydrogel with apatite-forming ability was obtained through the incorporation of K+ and Ca2+ ions into the solution
Almost rejectionless sampling from Nakagami-m distributions (m ≥ 1)

The Nakagami-m distribution is widely used for the simulation of fading channels in wireless communications. A novel, simple and extremely efficient acceptance-rejection algorithm is introduced for the generation of independent Nakagami-m random variables. The proposed method uses another Nakagami density with a half-integer value of the fading parameter, mp ¼ n/2 ≤ m, as proposal function, from\ud
which samples can be drawn exactly and easily. This novel rejection technique is able to work with arbitrary values of m ≥ 1, average path energy, V, and provides a higher acceptance rate than all currently available methods.\ud

Control of across-wind vortex shedding induced vibrations in tall buildings using the tuned mass-damper-inerter (TMDI)

In this paper, the effectiveness of the tuned mass-damper-inerter (TMDI) vis-à-vis the classical tuned mass-damper (TMD) is assessed to suppress vortex shedding induced vibrations to tall building structures in the across-wind direction. The TMDI, previously proposed in the literature to mitigate earthquake-induced vibrations in multi-storey buildings, benefits from the mass amplification effect of the inerter (i.e., a two-terminal device developing a resisting force proportional to the relative acceleration of its terminals by the inertance constant) to achieve improved vibration suppression performance from the classical TMD for the same attached mass. Herein, a linear reduced-order structural system is developed, defined by a diagonal mass matrix and full damping and stiffness matrices, which captures faithfully the dynamic properties of a detailed finite element model corresponding to a benchmark 74-storey building with square floor plan. A TMDI is added to the structural system by elementary operations to the mass, damping, and stiffness matrices under the assumption of an ideal linear inerter. The wind action is represented by an analytical spectral density matrix modelling correlated across-wind induced forces accounting for vortex shedding and the structural analysis step is undertaken in the frequency domain for efficiency. A comprehensive parametric analysis is undertaken demonstrating that the TMDI achieves better performance in terms of peak top floor acceleration reduction with increasing inertance than a classical TMD with the same attached mass. This is also true for relatively small attached masses of practical interest to tall buildings (less than 0.5% the total buildings mass) for the case of peak top floor displacements. Further, it is shown that the TMDI reduces significantly the peak attached mass displacement, while the peak developing forces at the inerter are not excessive and can be locally accommodated by the building
A search for top squarks with R-parity-violating decays to all-hadronic final states with the ATLAS detector in root s=8 TeV proton-proton collisions

Çetin, Serkant Ali (Dogus Author)A search for the pair production of top squarks, each with R-parity-violating decays into two Standard Model quarks, is performed using 17.4 fb(-1) of root s = 8 TeV proton-proton collision data recorded by the ATLAS experiment at the LITC. Each top squark is assumed to decay to a b- and an 8-quark, leading to four quarks in the final state. Background discrimination is achieved with the use of b-tagging and selections on the mass and substructure of large-radius jets, providing sensitivity to top squark masses as low as 100 GeV. No evidence of an excess beyond the Standard Model background prediction is observed and top squalls decaying to bs are excluded for top squark masses in the range 100 <= m((t) over tilde) <= 315 GeV at 95% confidence level
Lung stereotactic body radiotherapy with an MR-linac - Quantifying the impact of the magnetic field and real-time tumor tracking

Background and purpose: There are concerns that radiotherapy doses delivered in a magnetic field might be distorted due to the Lorentz force deflecting secondary electrons. This study investigates this effect on lung stereotactic body radiotherapy (SBRT) treatments, conducted either with or without multileaf collimator (MLC) tumor tracking. Material and methods: Lung SBRT treatments with an MR-linac were simulated for nine patients. Two different treatment techniques were compared: conventional, non-tracked deliveries and deliveries with real-time MLC tumor tracking, each conducted either with or without a 1.5 T magnetic field. Results: Slight dose distortions at air-tissue-interfaces were observed in the presence of the magnetic field. Most prominently, the dose to 2% of the skin increased by 1.4 Gy on average. Regardless of the presence of the magnetic field, MLC tracking was able to spare healthy tissue, for example by decreasing the mean lung dose by 0.3 Gy on average, while maintaining the target dose. Conclusions: Accounting for the magnetic field during treatment plan optimization allowed for design and delivery of clinically acceptable lung SBRT treatments with an MR-linac. Furthermore, the ability of MLC tumor tracking to decrease dose exposure of healthy tissue, was not inhibited by the magnetic field. (C) 2016 The Author(s). Published by Elsevier Ireland Ltd
NLO and off-shell effects in top quark mass determinations.

We study the impact of different theoretical descriptions of top quark pair production on top quark mass measurements in the di-lepton channel. To this aim, the full NLO corrections to   pp→W+W−bb¯¯→(e+νe)(μ−ν¯¯¯μ)bb¯¯  production are compared to calculations in the narrow width approximation, where the production of a top quark pair is calculated at NLO and combined with three different descriptions of the top quark decay: leading order, next-to-leading order and via a parton shower. The different theory predictions then enter the calibration of template fit functions, which are used for a fit to pseudo-data. The offsets in the top quark mass resulting from the fits based on the various theoretical descriptions are determined
Multimodel response assessment for monthly rainfall distribution in some selected Indian cities using best-fit probability as a tool

We carry out a study of the statistical distribution of rainfall precipitation data for 20 cites in India . We have determined the best-fit probability distribution for these cities from the monthly precipitation data spanning 100 years of observations from 1901 to 2002. To fit the observed data, we considered 10 different distributions. The efficacy of the fits for these distributions was evaluated using four empirical nonparametric goodness-of-fit tests, namely Kolmogorov–Smirnov, Anderson–Darling, Chi-square test, Akaike information criterion, and Bayesian information criterion. Finally, the best-fit distribution using each of these tests were reported, by combining the results from the model comparison tests . We then find that for most of the cities, generalized extreme value distribution or inverse Gaussian distribution most adequately fits the observed data
Measurement of B meson production cross-sections in proton-proton collisions at s√=7 TeV

The production cross-sections of B mesons are measured in pp collisions at a centre-of-mass energy of 7 TeV, using data collected with the LHCb detector corresponding to a integrated luminosity of 0.36 fb−1. The B +, B 0 and B0s mesons are reconstructed in the exclusive decays B + → J/ψK +, B 0 → J/ψK *0 and B0s→J/ψϕ , with J/ψ → μ + μ −, K *0 → K +π− and ϕ → K + K − . The differential cross-sections are measured as functions of B meson transverse momentum p T and rapidity y, in the range 0 < p T < 40 GeV/c and 2.0 < y < 4.5. The integrated cross-sections in the same p T and y ranges, including charge-conjugate states, are measured to be σ(pp→B++X) =38.9±0.3(stat.)±2.5(syst.)±1.3(norm.)μb,σ(pp→B0+X) =38.1±0.6(stat.)±3.7(syst.)±4.7(norm.)μb,σ(pp→B0s+X) =10.5±0.2(stat.)±0.8(syst.)±1.0(norm.)μb, where the third uncertainty arises from the pre-existing branching fraction measurements
Activity of upper body muscles during bowing and prostration tasks in healthy subjects

This paper investigate the activity of the neck extensors (NE), sternocleidomastoideus (SCM), trapezius (TRP), deltoid (DT), biceps brachii (BB), triceps brachii (TB), rectus abdominal (RA), and erector spine (ES) muscles in healthy subjects during bowing and prostration using surface electromyography (EMG). A group of student aged between 23 to 28 years voluntarily participated in this study. The subjects were asked to perform two types of flexion positions, namely bowing (90Â° forward flexion with the hands on the respective knees) and prostration (flexion with the palms of the hands and the forehead flat on the floor). The motion signals of the muscles were recorded. The finding indicated that during the bowing, there was contraction of the NE, DT, TB, and RA muscles while the muscle relaxation was found in the SCM, TRP, BB, and ES. During prostration, there was contraction at the SCM, DT, TB, and RA but muscle relaxation was found at the NE, TRP, BB, and ES. For the muscles that showed electrical activity in both the postures, the Wilcoxon Rank Sum Test showed a statistically no significant difference between bowing and prostration only for DT (p = 0.534) and but statistically significant difference for RA and TB (p<0.05). The muscle relaxation that existed at the ES showed no significant difference between bowing and prostrating (Wilcoxon Rank Sum Test, p = 0.075). This study indicates the effects of bowing and prostration on the biomechanical response of the human muscles. Muscle contraction and relaxation that occur, show an agonist-antagonist response which is good for exercise and strengthening programmers. These two movements are involved in the Muslim's prayer, called the salat. Hence, the current experiment can be taken as a pilot study on the biomechanical response of the human muscles during one's act of performing the salat. Â© 2011 Springer-Verlag
The Hermitian Laplace Operator on Nearly K\"ahler Manifolds

The moduli space NK of infinitesimal deformations of a nearly K\"ahler
structure on a compact 6-dimensional manifold is described by a certain
eigenspace of the Laplace operator acting on co-closed primitive (1,1) forms.
Using the Hermitian Laplace operator and some representation theory, we compute
the space NK on all 6-dimensional homogeneous nearly K\"ahler manifolds. It
turns out that the nearly K\"ahler structure is rigid except for the flag
manifold F(1,2)=SU_3/T^2, which carries an 8-dimensional moduli space of
infinitesimal nearly K\"ahler deformations, modeled on the Lie algebra su_3 of
the isometry group.Comment: 23 page
Simultaneous Multiwavelength Observations of Markarian 421 During
  Outburst

We report on the results of two coordinated multiwavelength campaigns that
focused on the blazar Markarian 421 during its 2006 and 2008 outbursts. These
campaigns obtained UV and X-ray data using the XMM-Newton satellite, while the
gamma-ray data were obtained utilizing three imaging atmospheric Cerenkov
telescopes, the Whipple 10m telescope and VERITAS, both based in Arizona, as
well as the MAGIC telescope, based on La Palma in the Canary Islands. The
coordinated effort between the gamma-ray groups allowed for truly simultaneous
data in UV/X-ray/gamma-ray wavelengths during a significant portion of the
XMM-Newton observations. This simultaneous coverage allowed for a reliable
search for correlations between UV, X-ray and gamma-ray variability over the
course of the observations. Investigations of spectral hysteresis and modeling
of the spectral energy distributions are also presented.Comment: 27 pages, 5 figures, Accepted for publication in The Astrophysical

The evolutionary limit for models of populations interacting
  competitively with many resources

We consider a integro-differential nonlinear model that describes the
evolution of a population structured by a quantitative trait. The interactions
between traits occur from competition for resources whose concentrations depend
on the current state of the population. Following the formalism of\cite{DJMP},
we study a concentration phenomenon arising in the limit of strong selection
and small mutations. We prove that the population density converges to a sum of
Dirac masses characterized by the solution $\phi$ of a Hamilton-Jacobi equation
which depends on resource concentrations that we fully characterize in terms of
the function $\phi$
The impact of the air-fluorescence yield on the reconstructed shower
  parameters of ultra-high energy cosmic rays

An accurate knowledge of the fluorescence yield and its dependence on
atmospheric properties such as pressure, temperature or humidity is essential
to obtain a reliable measurement of the primary energy of cosmic rays in
experiments using the fluorescence technique. In this work, several sets of
fluorescence yield data (i.e. absolute value and quenching parameters) are
described and compared. A simple procedure to study the effect of the assumed
fluorescence yield on the reconstructed shower parameters (energy and shower
maximum depth) as a function of the primary features has been developed. As an
application, the effect of water vapor and temperature dependence of the
collisional cross section on the fluorescence yield and its impact on the
reconstruction of primary energy and shower maximum depth has been studied.Comment: Accepted in Astroparticle Physic
