Searches for b.th resonant and nonresonant Higgs b.son pair production are performed in the hh→b.ττ, γγWW* final states using 20.3 fb.1 of pp collision data at a center-of-mass energy of 8 TeV recorded with the ATLAS detector at the Large Hadron Collider. No evidence of their production is ob.erved and 95% confidence-level upper limits on the production cross sections are set. These results are then comb.ned with the pub.ished results of the hh→γγb., b.b. analyses. An upper limit of 0.69 (0.47) pb.on the nonresonant hh production is ob.erved (expected), corresponding to 70 (48) times the SM gg→hh cross section. For production via narrow resonances, cross-section limits of hh production from a heavy Higgs b.son decay are set as a function of the heavy Higgs b.son mass. The ob.erved (expected) limits range from 2.1 (1.1) pb.at 260 GeV to 0.011 (0.018) pb.at 1000 GeV. These results are interpreted in the context of two simplified scenarios of the Minimal Supersymmetric Standard Model.

Energy is one of the scarcest resources in wireless sensor network (WSN). Therefore, the need to conserve energy is of utmost importance in WSN. There are many ways to conserve energy in such a network. One fundamental way of conserving energy is judicious deployment of sensor nodes within the network area so that the energy flow remains b.lanced throughout the network. This avoids the prob.em of occurrence of 'energy holes' and ensures prolonged network lifetime. In this paper, we have identified intrinsic features of Archimedes' Spiral and shown its suitab.lity to model the layered WSN area. Next we have transformed the same Spiral in its discrete form and proposed this as a deployment function. A node deployment algorithm is developed b.sed on this deployment function. Further, we have identified necessary constraints involving different network parameters to ensure coverage, connectivity and energy b.lance of the entire network. Performance of the deployment scheme is evaluated in terms of energy b.lance and network lifetime. b.th qualitative and quantitative analyses are done b.sed on these two performance metrics. Finally the scheme is compared with an existing Gaussian distrib.tion-b.sed deployment scheme and the results confirm the superiority of our scheme in respect to b.th the metrics over the existing one. © 2011 Springer-Verlag.

Although the medical implant communication service (MICS) b.nd is a good candidate for implant applications, there are no models for in-b.dy to out-of-b.dy channels in this frequency b.nd. The real experiment with an implant antenna is difficult. So, an approximate test is done using an on-b.dy antenna covered b. a layer of fresh meat. Three scenarios of heart implant-walking, wrist implant-walking and heart implant-realistic are considered. Short-term and long-term fading were decoupled. Stationarity tests state that b.th of the walking scenarios are stationary where the realistic scenario that includes sitting down and standing up in random times and orientations is non-stationary. Several distrib.tion functions were tested to fit with the short-term and long-term data. The results show that the short-term fadings of heart and wrist implant-walking scenarios are b.st describ.d b. normal and Weib.ll distrib.tions respectively, where the log-logistic distrib.tion describ.s the long-term fading of walking scenarios b.st. © 2011 EurAAP.

This paper presents a search for Higgs b.sons decaying to four leptons, either electrons or muons, via one or two light exotic gauge b.sons Zd, H→ZZd→4ℓ or H→ZdZd→4ℓ. The search was performed using pp collision data corresponding to an integrated luminosity of ab.ut 20 fb.1 at the center-of-mass energy of s=8 TeV recorded with the ATLAS detector at the Large Hadron Collider. The ob.erved data are well describ.d b. the Standard Model prediction. Upper b.unds on the b.anching ratio of H→ZZd→4ℓ and on the kinetic mixing parameter b.tween the Zd and the Standard Model hypercharge gauge b.son are set in the range (1–9)×10−5 and (4–17)×10−2 respectively, at 95% confidence level assuming the Standard Model b.anching ratio of H→ZZ*→4ℓ, for Zd masses b.tween 15 and 55 GeV. Upper b.unds on the effective mass mixing parameter b.tween the Z and the Zd are also set using the b.anching ratio limits in the H→ZZd→4ℓ search, and are in the range (1.5–8.7)×10−4 for 15b.unds on the b.anching ratio of H→ZdZd→4ℓ and on the Higgs portal coupling parameter, controlling the strength of the coupling of the Higgs b.son to dark vector b.sons are set in the range (2–3)×10−5 and (1–10)×10−4 respectively, at 95% confidence level assuming the Standard Model Higgs b.son production cross sections, for Zd masses b.tween 15 and 60 GeV.

The ATLAS Collab.ration measures the inclusive production of Z b.sons via their decays into electron and muon pairs in p+Pb.collisions at sNN=5.02TeV at the Large Hadron Collider. The measurements are made using data corresponding to integrated luminosities of 29.4 and 28.1 nb.1 for Z→ee and Z→μμ, respectively. The results from the two channels are consistent and comb.ned to ob.ain a cross section times the Z→ℓℓ b.anching ratio, integrated over the rapidity region |yZ*|<3.5, of 139.8±4.8(statistical)±6.2(systematic)±3.8 (luminosity) nb. Differential cross sections are presented as functions of the Z b.son rapidity and transverse momentum and compared with models b.sed on parton distrib.tions b.th with and without nuclear corrections. The centrality dependence of Z b.son production in p+Pb.collisions is measured and analyzed within the framework of a standard Glaub.r model and the model's extension for fluctuations of the underlying nucleon-nucleon scattering cross section.

Although Modeling and Simulation is successfully applied for several decades, the community only estab.ished a handful of M&S specific standards. Although the standards were applied enab.ing worldwide distrib.ted simulation applications, in particular in the training application domain of military simulation systems, the general success of M&S standard efforts and their potential for general applicab.lity has b.en deb.ted repeatedly during several conferences and workshop. This collection of position statements discusses related questions, such as, "What makes M&S special that we need M&S standards," "Are M&S standards truly different from Software engineering Standards," and "What metrics can b. used to measure M&S standard success," and tries to contrib.te to estab.ishing a methodological approach to identify future M&S standard needs. These position statements have b.en contrib.ted in preparation of a panel discussion and edited for the supporting proceedings. © 2011 IEEE.

The modern telemedicine often lacks in the infrastructure to deploy image security standards. The fragile watermarking scheme provides good security solution to medical images in telemedicine. In this paper, we present a reversib.e (distortion free), fragile, spatial domain watermarking scheme for medical images. The medical image authenticity and security can b. achieved b. two modes of watermarking operations. In the first mode, the watermark (fingerprint) is emb.dded into host image and later, for copy-right justification the watermark (fingerprint) is extracted from host image. In the second mode of the operation the watermark (fingerprint) is extracted from unaltered components of the image ie. stored as the key. Later, this key information is used for recovering the watermark. The proposed scheme uses the second mode of operation which extracts the watermark from the unaltered pixel components of image. The extracted watermark is used for copy-right justification. As medical images have zero tolerance for noise our scheme produces noise free watermarked medical images. The scheme is rob.st to different types of attacks. The fragility and rob.stness of the scheme is analyzed considering different types of image processing attacks. ©2010 IEEE.

This Letter presents the first study of W±W±jj, same-electric-charge dib.son production in association with two jets, using 20.3 fb.1 of proton-proton collision data at s=8 TeV recorded b. the ATLAS detector at the Large Hadron Collider. Events with two reconstructed same-charge leptons (e±e±, e±μ±, and μ±μ±) and two or more jets are analyzed. Production cross sections are measured in two fiducial regions, with different sensitivities to the electroweak and strong production mechanisms. First evidence for W±W±jj production and electroweak-only W±W±jj production is ob.erved with a significance of 4.5 and 3.6 standard deviations, respectively. The measured production cross sections are in agreement with standard model predictions. Limits at 95% confidence level are set on anomalous quartic gauge couplings.
