Higgs boson mass and complex sneutrino dark matter in the supersymmetric inverse seesaw models

The discovery of a relatively heavy Standard Model (SM)-like Higgs boson challenges naturalness of the minimal supersymmetric standard model (MSSM) from both Higgs and dark matter (DM) sectors. We study these two aspects in the MSSM extended by the low-scale inverse seesaw mechanism. Firstly, it admits a sizable radiative contribution to the Higgs boson mass m h , up to ~4 GeV in the case of an IR-fixed point of the coupling Y ν LH u ν c and a large sneutrino mixing. Secondly, the lightest sneutrino, highly complex as expected, is a viable thermal DM candidate. Owing to the correct DM relic density and the XENON100 experimental constraints, two scenarios survive: a Higgs-portal complex DM with mass lying around the Higgs pole or above W threshold, and a coannihilating DM with slim prospect of detection. Given an extra family of sneutrinos, both scenarios naturally work when we attempt to suppress the DM left-handed sneutrino component, confronting with enhancing m h
Precise Higgs-background predictions: merging NLO QCD and squared quark-loop corrections to four-lepton + 0,1 jet production

We present precise predictions for four-lepton plus jets production at the LHC obtained within the fully automated S herpa + O pen L oops framework. Off-shell intermediate vector bosons and related interferences are consistently included using the complex-mass scheme. Four-lepton plus 0- and 1-jet final states are described at NLO accuracy, and the precision of the simulation is further increased by squared quark-loop NNLO contributions in the gg → 4 ℓ , gg → 4 ℓ + g, g q → 4 ℓ + q , and $ q\overline{q} $ → 4 ℓ + g channels. These NLO and NNLO contributions are matched to the S herpa parton shower, and the 0- and 1-jet final states are consistently merged using the M eps @N lo technique. Thanks to Sudakov resummation, the parton shower provides improved predictions and uncertainty estimates for exclusive observables. This is important when jet vetoes or jet bins are used to separate four-lepton final states arising from Higgs decays, diboson production, and top-pair production. Detailed predictions are presented for the Atlas and C ms H → WW * analyses at 8 TeV in the 0- and 1-jet bins. Assessing renormalisation-, factorisation- and resummationscale uncertainties, which reflect also unknown subleading Sudakov logarithms in jet bins, we find that residual perturbative uncertainties are as small as a few percent
Neutron angular distribution in ( γ , n) reactions with linearly polarized γ -ray beam generated by laser Compton scattering

In 1957, Agodi predicted that the neutron angular distribution in ( γ , n) reactions with a 100% linearly polarized γ -ray beam for dipole excitation should be anisotropic and universally described by the simple function of a+b⋅cos⁡(2ϕ) at the polar angle θ=90° , where ϕ is the azimuthal angle. However, this prediction has not been experimentally confirmed in over half a century. We have verified experimentally this angular distribution in the ( γ , n) reaction for 197 Au, 127 I, and natural Cu targets using linearly polarized laser Compton scattering γ -rays. The result suggests that the ( γ→ , n) reaction is a novel tool to study nuclear physics in the giant dipole resonance region
The Zee–Babu model revisited in the light of new data

We update previous analyses of the Zee–Babu model in the light of new data, e.g., the mixing angle <math altimg="si1.gif" xmlns="http://www.w3.org/1998/Math/MathML"><msub><mrow><mi>θ</mi></mrow><mrow><mn>13</mn></mrow></msub></math> , the rare decay <math altimg="si2.gif" xmlns="http://www.w3.org/1998/Math/MathML"><mi>μ</mi><mo stretchy="false">→</mo><mi>e</mi><mi>γ</mi></math> and the LHC results. We also analyze the possibility of accommodating the deviations in <math altimg="si3.gif" xmlns="http://www.w3.org/1998/Math/MathML"><mi>Γ</mi><mo stretchy="false">(</mo><mi>H</mi><mo stretchy="false">→</mo><mi>γ</mi><mi>γ</mi><mo stretchy="false">)</mo></math> hinted by the LHC experiments, and the stability of the scalar potential. We find that neutrino oscillation data and low energy constraints are still compatible with masses of the extra charged scalars accessible to LHC. Moreover, if any of them is discovered, the model can be falsified by combining the information on the singly and doubly charged scalar decay modes with neutrino data. Conversely, if the neutrino spectrum is found to be inverted and the CP phase δ is quite different from π , the masses of the charged scalars will be well outside the LHC reach
Exploring practice characteristics and research priorities of practitioners of traditional acupuncture in China and the EU-A survey

ETHNOPHARMACOLOGICAL RELEVANCE: Acupuncture practice is based on the theoretical, historical and philosophical principles, which are part of Chinese medicine. Traditional acupuncture practitioners assess their patients' conditions using Chinese medicine diagnostic techniques, which determine clinical care and treatment. Little is known about differences in the perceptions of research evidence among practitioners in the European Union (EU) and China, given the diversity of acupuncture practice. MATERIAL AND METHODS: This study explored differences between practitioners of traditional acupuncture regarding perceived need for research evidence and prioritisation for future clinical trials, based on their practice within the EU and China. A convenience sample of acupuncturists in the EU (contacted by their professional organisation) and China (from geographically dispersed hospitals) were invited to participate in a survey, which was conducted during 2010/2011. Data collected included: practitioners' demographic details, country of training, practice setting, acupuncture techniques, perceived adverse event reporting, diagnostic methods, conditions commonly treated, conditions perceived as needing more evidence and practitioner perceptions of conditions which could demonstrate benefit if investigated in clinical trials. RESULTS: From 1126 survey responses, 1020 (559 EU, 461 China) could be included in the analysis for direct comparison. A response rate for the EU could not be calculated but for China was 98%. Pain was the most frequently reported commonly treated condition by EU acupuncturists and neurological conditions (mainly stroke) for Chinese practitioners. The top reported priorities for research were obstetrics/gynaecological conditions in the EU and neurological problems in China. CONCLUSION: The survey identified differences in practice and training between acupuncturists in China and the EU and between EU member states. These differences may inform prioritisation of health conditions for future trials. Innovative research methods are recommended to incorporate the complexity and plurality of acupuncture practice and theory. Creation of collaborative networks is crucial in overcoming these differences to facilitate international, multi-centre clinical trials
Identification of new susceptibility loci for osteoarthritis (arcOGEN): a genome-wide association study.

To access publisher's full text version of this article. Please click on the hyperlink in Additional Links field.Osteoarthritis is the most common form of arthritis worldwide and is a major cause of pain and disability in elderly people. The health economic burden of osteoarthritis is increasing commensurate with obesity prevalence and longevity. Osteoarthritis has a strong genetic component but the success of previous genetic studies has been restricted due to insufficient sample sizes and phenotype heterogeneity.\ud
We undertook a large genome-wide association study (GWAS) in 7410 unrelated and retrospectively and prospectively selected patients with severe osteoarthritis in the arcOGEN study, 80% of whom had undergone total joint replacement, and 11,009 unrelated controls from the UK. We replicated the most promising signals in an independent set of up to 7473 cases and 42,938 controls, from studies in Iceland, Estonia, the Netherlands, and the UK. All patients and controls were of European descent.\ud
We identified five genome-wide significant loci (binomial test p≤5·0×10(-8)) for association with osteoarthritis and three loci just below this threshold. The strongest association was on chromosome 3 with rs6976 (odds ratio 1·12 [95% CI 1·08-1·16]; p=7·24×10(-11)), which is in perfect linkage disequilibrium with rs11177. This SNP encodes a missense polymorphism within the nucleostemin-encoding gene GNL3. Levels of nucleostemin were raised in chondrocytes from patients with osteoarthritis in functional studies. Other significant loci were on chromosome 9 close to ASTN2, chromosome 6 between FILIP1 and SENP6, chromosome 12 close to KLHDC5 and PTHLH, and in another region of chromosome 12 close to CHST11. One of the signals close to genome-wide significance was within the FTO gene, which is involved in regulation of bodyweight-a strong risk factor for osteoarthritis. All risk variants were common in frequency and exerted small effects.\ud
Our findings provide insight into the genetics of arthritis and identify new pathways that might be amenable to future therapeutic intervention
Near real time regional moment tensor estimation using italian broadband stations

Since 2002, the Istituto Nazionale di Geofisica e Vulcanologia (INGV) in Rome has started the installation of a high quality
regional broadband network throughout the Italian territory. Up today, the network consists of 125 stations equipped with 40 s
natural period instruments. The dense station coverage allows for the implementation of real-time regional moment tensor (MT)
estimation procedures such as that proposed by Dreger and Helmberger (1993).
The automatic MT algorithm uses real-time broadband waveforms continuously telemetered to INGV, and it is triggered for events
with magnitude greater than Ml 3.5. This is the lowermost value for which we have found it possible to obtain reliable MT determination
in the frequency band used in the inversion. The automatic solution is available within about 3-5 minutes after the earthquake
location. Each solution has an assigned quality factor dependent on the number of the station used in the inversion, and the godness
of fit between synthetic and observed data. MT is published on the web after revision by a seismologist.
Efforts are also made to evaluate MT solutions for earthquakes occurring in Italy and neighboring regions in the last years. The
results are compared to those obtained from application of other moment tensor methods. It is always found a good agreement
between the newly determined solutions and those from other methods.
Overall, fast and accurate moment tensor solutions are an important ingredient when attempting to estimate the recorded ground
shaking. Overall, in Italy, earthquakes in the magnitude range 3.5 – 5 are very common; the availability of their focal mechanisms
allows the mapping of the principal stress field axes leading to a better understanding of the ongoing tectonics
Source process of the September 12, 2007 MW 8.4 Southern Sumatra earthquake from tsunami tide gauge record inversion

We infer the slip distribution and average rupture velocity of the magnitude MW 8.4 September 12, 2007, Southern Sumatra earthquake from available tide-gauge records of the ensuing tsunami. We select 9 waveforms recorded along the west coast of Sumatra and in the Indian Ocean. We assume the fault plane and the slip direction to be consistent with both the geometry of the subducting plate and the early focal mechanism solutions. Slip distribution and rupture velocity are determined simultaneously by means of a non linear inversion method. We find high slip values (∼10 m) into a patch 100 km long and 50 km large, between 20 and 30 km of depth, about 100 km north-west from the epicenter. Our estimate of rupture velocity is of 2.1±0.4 km/sec. The relatively large depth of the main slip patch is the likely explanation for the small observed tsunami
Development of a method for determination of VOCs (including methylsiloxanes) in biogas by TD-GC/MS analysis using Supel (TM) Inert Film bags and multisorbent bed tubes

An analytical method based on TD-GC/MS was developed and validated for the determination of volatile organic compounds (VOCs), including linear and cyclic volatile methylsiloxanes (VMSs), in biogas. Biogas was first sampled in Supel (TM) Inert Film bags and subsequently dynamically sampled onto multisorbent bed tubes (Carbotrap, Carbopack X and Carboxen 569) using portable pump equipment. Two sample volumes, 100 and 250ml, were evaluated. Desorption efficiency values for both volumes are in the range of 99-100% for almost all studied compounds while breakthrough values (%VOC on sample tube back section) are below 1% for most evaluated VOCs. However, acetaldehyde, carbon disulphide, ethanol and 1,3-butadiene have breakthrough values higher than 5%. Method detection limits were in the range of 0.01-0.8 ng per sample. The most abundant VOCs in biogas were terpenes with concentrations between 500 and 700mgm(-3). Other important families were ketones, aromatic hydrocarbons and alkanes, with concentrations in the range of 36-46, 20-35 and 14-16mgm(-3), respectively. VMSs presented average concentrations of 4.9 +/- 0.4mgm(-3). Additionally, the Supel (TM) Inert Film bags were evaluated for stability for 4days at room temperature. Although several VOC families' concentrations in the bag increased or decreased significantly (t-test; p <= 0.01, n=5) 2days after collection, recoveries were around 70-130% for most studied VOCs. The results shown demonstrate that the presented methodology is reliable and satisfactory for the evaluation of VOCs in biogas and presents an alternative to the currently existing biogas analytical techniques.Peer ReviewedPostprint (author’s final draft
Habitual chocolate consumption and the risk of incident heart failure among healthy men and women

Background: We aimed to examine the association between chocolate intake and the risk of incident heart failure in a UK general population. We conducted a systematic review and meta-analysis to quantify this association. Methods and results: We used data from a prospective population-based study the European Prospective Investigation into Cancer (EPIC)-Norfolk cohort. Chocolate intake was quantified based on a food frequency questionnaire obtained at baseline (1993-1997) and incident heart failure was ascertained up to March 2009. We supplemented the primary data with a systematic review and meta-analysis of studies which evaluated risk of incident heart failure with chocolate consumption. A total of 20,922 participants (53% women; mean age 58±9 years) were included of whom 1,101 developed heart failure during the follow up (mean 12.5±2.7 years, total person years 262,291 years). After adjusting lifestyle and dietary factors, we found 19% relative reduction in heart failure incidence in the top (up to 100g/d) compared to the bottom quintile of chocolate consumption (HR 0.81 95%CI 0.66-0.98) but the results were no longer significant after controlling for comorbidities (HR 0.87 95%CI 0.71-1.06). Additional adjustment for potential mediators did not attenuate the results further. We identified five relevant studies including the current study (N=75,408). The pooled results showed non-significant 19% relative risk reduction of heart failure incidence with higher chocolate consumption (HR 0.81 95%CI 0.66-1.01). Conclusions: Our results suggest that higher chocolate intake is not associated with subsequent incident heart failure

HCO3−-independent pH Regulation in Astrocytes in Situ Is Dominated by V-ATPase

The mechanisms of HCO3−-independent intracellular pH (pHi) regulation were examined in fibrous astrocytes within isolated neonatal rat optic nerve (RON) and in cultured cortical astrocytes. In agreement with previous studies, resting pHi in cultured astrocytes was 6.82 ± 0.06 and inhibition of the V-ATPase H+ pump by Cl− removal or via the selective inhibitor bafilomycin had only a small effect upon resting pHi and recovery following an acid load. In contrast, resting pHi in RON astrocytes was 7.10 ± 0.04, significantly less acidic than that in cultured cells (p < 0.001), and responded to inhibition of V-ATPase with profound acidification to the 6.3–6.5 range. Fluorescent immuno-staining and immuno-gold labeling confirmed the presence V-ATPase in the cell membrane of RON astrocyte processes and somata. Using ammonia pulse recovery, pHi recovery in RON astrocyte was achieved largely via V-ATPase with sodium-proton exchange (NHE) playing a minor role. The findings indicate that astrocytes in a whole-mount preparation such as the optic nerve rely to a greater degree upon V-ATPase for HCO3−-independent pHi regulation than do cultured astrocytes, with important functional consequences for the regulation of pH in the CNS.This work was supported by Biotechnology and Biological Sciences Research Council (BBSRC) Grant BB/J016969/1 (to R.

Entropy current for non-relativistic fluid.

We study transport properties of a parity-odd, non-relativistic charged fluid in presence of background electric and magnetic fields. To obtain stress tensor and charged current for the non-relativistic system we start with the most generic relativistic fluid, living in one higher dimension and reduce the constituent equations along the light-cone direction. We also reduce the equation satisfied by the entropy current of the relativistic theory and obtain a consistent entropy current for the non-relativistic system (we call it “canonical form” of the entropy current). Demanding that the non-relativistic fluid satisfies the second law of thermodynamics we impose constraints on various first order transport coefficients. For parity even fluid, this is straight forward; it tells us positive definiteness of different transport coefficients like viscosity, thermal conductivity, electric conductivity etc. However for parity-odd fluid, canonical form of the entropy current fails to confirm the second law of thermodynamics. Therefore, we need to add two parity-odd vectors to the entropy current with arbitrary coefficients. Upon demanding the validity of second law, we see that one can fix these two coefficients exactly
New development : managing and accounting for sustainable development across generations in public services – and call for papers

Social and environmental justice across generations is a fundamental attribute of sustainable development. In this article, which is also a call for papers for a future theme in Public Money & Management (PMM), we develop our case for further research on how governments and public service organizations seek to address sustainable development in their decision-making processes. We believe that accounting for social and environmental aspects is an underdeveloped area of research and practice that is worthy of further critical enquiry. We therefore call on researchers and practitioners to submit their research to a themed issue of PMM on managing and accounting for sustainable development in public services
Direct photon production in Pb-Pb collisions at $\sqrt{s_\rm{NN}}$ =
  2.76 TeV

Direct photon production at mid-rapidity in Pb-Pb collisions at
$\sqrt{s_{_{\mathrm{NN}}}} = 2.76$ TeV was studied in the transverse momentum
range $0.9 < p_\mathrm{T} < 14$ GeV$/c$. Photons were detected with the highly
segmented electromagnetic calorimeter PHOS and via conversions in the ALICE
detector material with the $e^+e^-$ pair reconstructed in the central tracking
system. The results of the two methods were combined and direct photon spectra
were measured for the 0-20%, 20-40%, and 40-80% centrality classes. For all
three classes, agreement was found with perturbative QCD calculations for
$p_\mathrm{T} \gtrsim 5$ GeV$/c$. Direct photon spectra down to $p_\mathrm{T}
\approx 1$ GeV$/c$ could be extracted for the 20-40% and 0-20% centrality
classes. The significance of the direct photon signal for $0.9 < p_\mathrm{T} <
2.1$ GeV$/c$ is $2.6\sigma$ for the 0-20% class. The spectrum in this
$p_\mathrm{T}$ range and centrality class can be described by an exponential
with an inverse slope parameter of $(297 \pm 12^\mathrm{stat}\pm
41^\mathrm{syst})$ MeV. State-of-the-art models for photon production in
heavy-ion collisions agree with the data within uncertainties.Comment: 25 pages, 6 captioned figures, 2 tables, authors from page 20,

On-Shell Diagrams for N = 8 Supergravity Amplitudes

We define recursion relations for N = 8 supergravity amplitudes using a
generalization of the on-shell diagrams developed for planar N = 4
super-Yang-Mills. Although the recursion relations generically give rise to
non-planar on-shell diagrams, we show that at tree-level the recursion can be
chosen to yield only planar diagrams, the same diagrams occurring in the planar
N = 4 theory. This implies non-trivial identities for non-planar diagrams as
well as interesting relations between the N = 4 and N = 8 theories. We show
that the on-shell diagrams of N = 8 supergravity obey equivalence relations
analogous to those of N = 4 super-Yang-Mills, and we develop a systematic
algorithm for reading off Grassmannian integral formulae directly from the
on-shell diagrams. We also show that the 1-loop 4-point amplitude of N = 8
supergravity can be obtained from on-shell diagrams.Comment: v3. minor changes, published in JHE
