Bioinformatic analysis using complex networks and clustering proteins involved with Alzheimer's disease.

The detection of protein complexes is an important research problem in bioinformatics, which may help increase our understanding of the biological functions of proteins inside our body. Moreover, new discoveries obtained from identification of protein complexes may be considered important for therapeutic purposes. Several proteins linked with Alzheimer’s disease were investigated. By observing the connectivity between proteins using computational methods such as graph theory and clustering, we can uncover previously unknown relationships that are useful for potential knowledge discovery. Furthermore, we demonstrate how Markov Clustering (MCL) and the Molecular Complex Detection (MCODE) algorithm identify interesting patterns from the protein-protein interaction data related to Alzheimer’s disease
Search for dark matter produced in association with a hadronically decaying vector boson in pp collisions at s=13 TeV with the ATLAS detector.

A search is presented for dark matter produced in association with a hadronically decaying W or Z boson using 3.2 fb−1 of pp   collisions at View the MathML sources=13 TeV recorded by the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet compatible with a W or Z boson and with large missing transverse momentum are analysed. The data are consistent with the Standard Model predictions and are interpreted in terms of both an effective field theory and a simplified model containing dark matter.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW and FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF and DNSRC, Denmark; IN2P3-CNRS, CEA-DSM/IRFU, France; GNSF, Georgia; BMBF, HGF, and MPG, Germany; GSRT, Greece; RGC, Hong Kong SAR, China; ISF, I-CORE and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; RCN, Norway; MNiSW and NCN, Poland; FCT, Portugal; MNE/IFA, Romania; MES of Russia and NRC KI, Russian Federation; JINR; MESTD, Serbia; MSSR, Slovakia; ARRS and MIZS, Slovenia; DST/NRF, South Africa; MINECO, Spain; SRC and Wallenberg Foundation, Sweden; SERI, SNSF and Cantons of Bern and Geneva, Switzerland; MOST, Taiwan; TAEK, Turkey; STFC, United Kingdom; DOE and NSF, United States of America.

On exact correlation functions in SU(N) N = 2\ud
superconformal QCD.

We consider the exact coupling constant dependence of extremal correlation functions of  N=2N=2  chiral primary operators in 4d  N=2N=2  superconformal gauge theories with gauge group SU(N) and Nf = 2N massless fundamental hypermultiplets. The 2- and 3-point functions, viewed as functions of the exactly marginal coupling constant and theta angle, obey the tt* equations. In the case at hand, the tt* equations form a set of complicated non-linear coupled matrix equations. We point out that there is an ad hoc self-consistent ansatz that reduces this set of partial differential equations to a sequence of decoupled semi-infinite Toda chains, similar to the one encountered previously in the special case of SU(2) gauge group. This ansatz requires a surprising new non-renormalization theorem in  N=2N=2  superconformal field theories. We derive a general 3-loop perturbative formula for 2- and 3-point functions in the  N=2N=2  chiral ring of the SU(N) theory, and in all explicitly computed examples we find agreement with the tt* equations, as well as the above-mentioned ansatz. This is suggestive evidence for an interesting non-perturbative conjecture about the structure of the  N=2N=2  chiral ring in this class of theories. We discuss several implications of this conjecture. For example, it implies that the holonomy of the vector bundles of chiral primaries over the superconformal manifold is reducible. It also implies that a specific subset of extremal correlation functions can be computed in the SU(N) theory using information solely from the S4 partition function of the theory obtained by supersymmetric localization
The fluvial flux of total reactive and total phosphorus from the UK in the context of a national phosphorus budget: comparing UK river fluxes with phosphorus trade imports and exports

A national river water quality database of total reactive phosphorus (TRP) and total phosphorus (TP) and flow was used, together with catchment characteristic datasets (soils, land use and hydroclimatic properties), to derive national fluvial phosphorus (P) flux estimates for Great Britain (England, Wales and Scotland) from 1974 to 2012.\ud
These fluvial P fluxes were compared with P imports\ud
and exports, in fertilizer, food, feedstuffs, and industrial\ud
products, along with coastal direct discharge of wastes, at the British national boundary from 1990 to 2012. The results showed that: (i) Average annual river TP concentrations in Great Britain have declined\ud
from a peak of 0.27–0.1 mg P/l and annual river TP flux has declined from 120 to 16 ktonnes P/year (0.49–0.06 tonnes P/km2/year); (ii) Average river TRP \ud
concentration has declined from a peak of 0.19–\ud
0.05 mg P/l and annual river TRP flux has declined \ud
from 71 to 10 ktonnes P/year (0.29–0.05 tonnes \ud
P/km2); (iii) Over the period 2003–2012, even after \ud
the introduction of the Urban Waste Water Directive,\ud
60 % of UK’s TP flux was still from urban areas; and \ud
(iv) In 1990, the fluvial flux of TP from the UK was \ud
equivalent to 41 % of imports; by 2012 this had \ud
decreased to 15 %. The UK (relative to its boundary)\ud
continues to accumulate P and, over the last 15 years,\ud
this accumulation has increased at an average rate of \ud
0.6 ktonnes P/year. Enhanced removal of P in waste \ud
water treatment has shifted the environmental pathway \ud
of sewage P from discharge to rivers to accumulation in sewage sludge, which is largely \ud
disposed of on agricultural land, and which could \ud
eventually provide a sustained legacy source of P to \ud
rivers for decades. However, a substantial proportion \ud
of P accumulation is via food waste into landfills
Isomerism in the “south-east” of 132Sn and a predicted neutron-decaying isomer in 129Pd

Excited states in neutron-rich nuclei located south-east of 132Sn are investigated by shell-model calculations. A new shell-model Hamiltonian is constructed for the present study. The proton–proton and neutron–neutron interactions of the Hamiltonian are obtained through the existing CD-Bonn G matrix results, while the proton–neutron interaction across two major shells is derived from the monopole based universal interaction plus the M3Y spin–orbit force. The present Hamiltonian can reproduce well the experimental data available in this region, including one-neutron separation energies, level energies and the experimental B(E2)B(E2) values of isomers in 134,136,138Sn, 130Cd, and 128Pd. New isomers are predicted in this region, e.g. in 135Sn, 131Cd, 129Pd, 132,134In and 130Ag, in which almost no excited states are known experimentally yet. In the odd–odd 132,134In and 130Ag, the predicted very long E 2 life-times of the low-lying 5−5− states are discussed, demanding more information on the related proton–neutron interaction. The low-lying states of 132In are discussed in connection with the recently observed γ rays. The predicted 19/2−19/2− isomer in 129Pd could decay by both electromagnetic transitions and neutron emission with comparable partial life-times, making it a good candidate for neutron radioactivity, a decay mode which is yet to be discovered
Fluorine directed two-dimensional cruciform π π stacking in diketopyrrolopyrroles

Enhanced bulk dimensionality in organic materials employed in optoelectronic devices is desirable and can overcome fabrication issues related to structural defects and grain boundaries. Herein, we report a novel fluorinated diketopyrrolopyrrole single crystal structure, which displays a unique, mutually orthogonal, 2 dimensional cruciform π π stacking arrangement. The crystal structure is characterised by an unusually large number of nearest neighbour dimer pairs which contribute to a greater thermal integrity than structurally analogous equivalents. Binding energies and charge transfer integrals were computed for all of the crystal extracted dimer pairs by means of M06-2X density functional at 6-311G(d) level. Although weak, a number of intermolecular interactions involving organic fluorine (C-F---H, πF---π and C-F---πF) were identified to influence the supramolecular assembly of these dimer pairs. Charge transfer integrals for the two π-π stacking crystal dimers were determined using the energy splitting in dimer method. Ambipolar charge transport favouring electron transfer approaching that of rubrene is predicted in both of these π-π stacks with a greater magnitude of coupling observed from those dimers perpetuating along the crystallographic a-axis. Charge transport behaviour in the single crystal is greatly influenced by selective fluorination of the N benzyl substituents and is consistent with the crystal extracted π-π stacking dimer geometries and their overall influence on wavefunction overlap. The reported structure is an interesting electron transport material that could be exploited, particularly in thin film based optoelectronic devices, where high bulk dimensionality is required
Latitudinal variability in Jupiter's tropospheric disequilibrium species: GeH4, AsH3 and PH3

Jupiter’s tropospheric composition is studied using high resolution spatially-resolved 5-µm observation from the CRIRES instrument at the Very Large Telescope. The high resolving power (R=96,000) allows us to spectrally resolve the line shapes of individual molecular species in Jupiter’s troposphere and, by aligning the slit north-south along Jupiter’s central meridian, we are able to search for any latitudinal variability. Despite the high spectral resolution, we find that there are significant degeneracies between the cloud structure and aerosol scattering properties that complicate the retrievals of tropospheric gaseous abundances and limit conclusions on any belt-zone variability. However, we do find evidence for variability between the equatorial regions of the planet and the polar regions. Arsine (AsH3) and phosphine (PH3) both show an enhancement at high latitudes, while the abundance of germane (GeH4) remains approximately constant. These observations contrast with the theoretical predictions from Wang et al. (2016) and we discuss the possible explanations for this difference.Giles was supported via a Royal Society studentship, and Fletcher was supported via a Royal Society Research Fellowship at the University of Leicester.

Measurement of the pseudorapidity and transverse momentum dependence of the elliptic flow of charged particles in lead–lead collisions at √sNN = 2.76 TeV with the ATLAS detector

This Letter describes the measurement of elliptic flow of charged particles in lead–lead collisions at √s[subscript NN]=2.76 TeV using the ATLAS detector at the Large Hadron Collider (LHC). The results are based on an integrated luminosity of approximately 7 μb[superscript −1]. Elliptic flow is measured over a wide region in pseudorapidity, |η|<2.5|, and over a broad range in transverse momentum, 0.5<pT<20 GeV. The elliptic flow parameter v2 is obtained by correlating individual tracks with the event plane measured using energy deposited in the forward calorimeters. As a function of transverse momentum, v2(pT) reaches a maximum at pT of about 3 GeV, then decreases and becomes weakly dependent on pT above 7–8 GeV. Over the measured pseudorapidity region, v2 is found to be only weakly dependent on η, with less variation than observed at lower beam energies. The results are discussed in the context of previous measurements at lower collision energies, as well as recent results from the LHC.United States. Dept. of EnergyNational Science Foundation (U.S.
Stakeholder attitudes on carbon capture and storage -- An international comparison

This paper presents results from a survey on stakeholder attitudes towards Carbon Capture and Storage (CCS). The survey is the first to make a global comparison across three major regions; USA, Japan, and Europe. The 30-question survey targeted individuals working at stakeholder organizations that seek to shape, and will need to respond to, policy on CCS, including electric utilities, oil & gas companies, CO2-intensive industries and non-governmental organizations (NGOs).
The results show generally small differences across the regions and between the different groups of stakeholders. All believed that the challenge of significant reductions in emissions using only current technologies was severe. There is a widespread belief both that renewable technologies such as solar power and CCS will achieve major market entry into the electricity sector within the next 10 to 20 years, whereas there is more skepticism about the role of hydrogen and especially nuclear fusion in the next 50 years. All groups were generally positive towards renewable energy. Yet, there were some notable areas of disagreement in the responses, for example, as expected, NGOs considered the threat of climate change to be more serious than the other groups. North Americans respondents were more likely to downplay the threat compared to those of the other regions. The Japanese were more concerned about the burden that would be placed on industry in the coming decade as a result of emissions constraints and NGOs were more likely to believe that the burden would be light or very light. NGOs believed CCS to be far more attractive than nuclear fusion power but much less than renewables. As expected, the risk for leakage from reservoirs was ranked number one of the risk options given.Alliance for Global SustainabilityNational Institute of Advanced Industrial Science and Technology (Japan)Carbon Sequestration InitiativeAlliance for Global Sustainability (AGS project “Pathways to Sustainable European Energy Systems” funding
Combined search for the Standard Model Higgs boson using up to 4.9 fb-1 of pp collision data at sqrt(s) = 7 TeV with the ATLAS detector at the LHC

A combined search for the Standard Model Higgs boson with the ATLAS experiment at the LHC using datasets corresponding to integrated luminosities from 1.04 fb-1 to 4.9 fb-1 of pp collisions collected at sqrt(s) = 7 TeV is presented. The Higgs boson mass ranges 112.9-115.5 GeV, 131-238 GeV and 251-466 GeV are excluded at the 95% confidence level (CL), while the range 124-519 GeV is expected to be excluded in the absence of a signal. An excess of events is observed around mH ~ 126 GeV with a local significance of 3.5 standard deviations (sigma). The local significance of H -> gamma gamma, H -> ZZ(*) -> lll'l' and H -> WW(*) -> lvl'v, the three most sensitive channels in this mass range, are 2.8 sigma, 2.1 sigma and 1.4 sigma, respectively. The global probability for the background to produce such a fluctuation anywhere in the explored Higgs boson mass range 110-600 GeV is estimated to be ~1.4% or, equivalently 2.2 sigma
All-loop correlators of integrable λ-deformed σ-models

We compute the 2- and 3-point functions of currents and primary fields of λ-deformed integrable σ-models characterized also by an integer k. Our results apply for any semisimple group G, for all values of the deformation parameter λ   and up to order 1/k. We deduce the OPEs and equal-time commutators of all currents and primaries. We derive the currents' Poisson brackets which assume Rajeev's deformation of the canonical structure of the isotropic PCM, the underlying structure of the integrable λ-deformed σ-models. We also present analogous results in two limiting cases of special interest, namely for the non-Abelian T-dual of the PCM and for the pseudodual model
Measurement of the CP-violating phase ϕs and the Bs0 meson decay width difference with Bs0 → J/ψϕ decays in ATLAS

A measurement of the Bs0 decay parameters in the Bs0 → J/ψϕ channel using an integrated luminosity of 14.3 fb−1 collected by the ATLAS detector from 8 TeV pp collisions at the LHC is presented. The measured parameters include the CP -violating phase ϕs, the decay width Γs and the width difference between the mass eigenstates ΔΓs. The values measured for the physical parameters are statistically combined with those from 4.9 fb−1 of 7 TeV data, leading to the following:ϕs=−0.090±0.078(stat.)±0.041(syst.)radΔΓs=0.085±0.011(stat.)±0.007(syst.)ps−1Γs=0.675±0.003(stat.)±0.003(syst.)ps−1.In the analysis the parameter ΔΓs is constrained to be positive. Results for ϕs and ΔΓs are also presented as 68% and 95% likelihood contours in the ϕs-ΔΓs plane. Also measured in this decay channel are the transversity amplitudes and corresponding strong phases. All measurements are in agreement with the Standard Model predictions
The light-yield response of a NE-213 liquid-scintillator detector measured using 2–6MeV tagged neutrons

AbstractThe response of a NE-213 liquid-scintillator detector has been measured using tagged neutrons from 2 to 6MeV originating from an Am/Be neutron source. The neutron energies were determined using the time-of-flight technique. Pulse-shape discrimination was employed to discern between gamma-rays and neutrons. The behavior of both the fast (35ns) and the combined fast and slow (475ns) components of the neutron scintillation-light pulses were studied. Three different prescriptions were used to relate the neutron maximum energy-transfer edges to the corresponding recoil-proton scintillation-light yields, and the results were compared to simulations. The overall normalizations of parametrizations which predict the fast or total light yield of the scintillation pulses were also tested. Our results agree with both existing data and existing parametrizations. We observe a clear sensitivity to the portion and length of the neutron scintillation-light pulse considered
General distress, hopelessness—suicidal ideation and worrying in adolescence: Concurrent and predictive validity of a symptom-level bifactor model for clinical diagnoses

AbstractBackgroundClinical disorders often share common symptoms and aetiological factors. Bifactor models acknowledge the role of an underlying general distress component and more specific sub-domains of psychopathology which specify the unique components of disorders over and above a general factor.MethodsA bifactor model jointly calibrated data on subjective distress from The Mood and Feelings Questionnaire and the Revised Children's Manifest Anxiety Scale. The bifactor model encompassed a general distress factor, and specific factors for (a) hopelessness—suicidal ideation, (b) generalised worrying and (c) restlessness—fatigue at age 14 which were related to lifetime clinical diagnoses established by interviews at ages 14 (concurrent validity) and current diagnoses at 17 years (predictive validity) in a British population sample of 1159 adolescents.ResultsDiagnostic interviews confirmed the validity of a symptom-level bifactor model. The underlying general distress factor was a powerful but non-specific predictor of affective, anxiety and behaviour disorders. The specific factors for hopelessness—suicidal ideation and generalised worrying contributed to predictive specificity. Hopelessness—suicidal ideation predicted concurrent and future affective disorder; generalised worrying predicted concurrent and future anxiety, specifically concurrent generalised anxiety disorders. Generalised worrying was negatively associated with behaviour disorders.LimitationsThe analyses of gender differences and the prediction of specific disorders was limited due to a low frequency of disorders other than depression.ConclusionsThe bifactor model was able to differentiate concurrent and predict future clinical diagnoses. This can inform the development of targeted as well as non-specific interventions for prevention and treatment of different disorders
Status of the Zee–Babu model for neutrino mass and possible tests at a like-sign linear collider

AbstractWe provide an updated scan of the allowed parameter space of the two-loop Zee–Babu model for neutrino mass. Taking into account most recent experimental data on μ→eγ as well as the mixing angle θ13 we obtain lower bounds on the masses of the singly and doubly charged scalars of between 1 and 2 TeV, with some dependence on perturbativity and fine-tuning requirements. This makes the scalars difficult to observe at LHC with 14 TeV even with optimistic assumptions on the luminosity, and would require a multi-TeV linear collider to see the scalar resonances. We point out, however, that a sub-TeV linear collider in the like-sign mode may be able to observe lepton flavor violating processes such as e−e−→μ−μ− due to contact interactions induced by the doubly charged scalar with masses up to around 10 TeV. We investigate the possibility to distinguish the Zee–Babu model from the Higgs triplet model using such processes
Informal Learning among Engineering Technology Teachers

AbstractThe purpose of this research is to investigate teachesr’ readiness in informal learning. A learning model was develop to help the teachers to understand the state of their readiness in teaching the Engineering Technology subject based on knowledge and management skills. The study was designed to answer questions on method used in of informal learning, factors that influence engagement in informal learning in the workplace, personal characteristic of the teachers, and the organization's learning culture. Using a set of questionnaire, data was collected from a group of Engineering Technology teachers and analysed using min score and percentage
Experimental investigation of the 02+ band in Sm154 as a β-vibrational band

AbstractA study of Sm154 through γ-ray and internal conversion electron coincidence measurements was performed using the Silicon And GErmanium spectrometer (SAGE). An upper limit for the ρ2(E0;22+→21+) and measurement of the ρ2(E0;42+→41+) monopole transitions strengths were determined. The extracted transition strength for each is significantly lower than that predicted by either the Bohr and Mottelson β-vibration description or the interacting boson model. Hence, the long standing interpretation of these states as a collective band built on the 02+ state, which is conventionally assigned as a Bohr and Mottelson β vibration is questionable
