Comb.ned measurements of Higgs b.son production cross sections and b.anching fractions are presented. The comb.nation is b.sed on the analyses of the Higgs b.son decay modes H→γγ, ZZ*, WW*, ττ, b.¯, μμ, searches for decays into invisib.e final states, and on measurements of off-shell Higgs b.son production. Up to 79.8 fb.1 of proton–proton collision data collected at s=13 TeV with the ATLAS detector are used. Results are presented for the gluon–gluon fusion and vector-b.son fusion processes, and for associated production with vector b.sons or top-quarks. The glob.l signal strength is determined to b. μ=1.11−0.08+0.09. The comb.ned measurement yields an ob.erved (expected) significance for the vector-b.son fusion production process of 6.5σ (5.3σ). Measurements in kinematic regions defined within the simplified template cross section framework are also shown. The results are interpreted in terms of modifiers applied to the Standard Model couplings of the Higgs b.son to other particles, and are used to set exclusion limits on parameters in two-Higgs-doub.et models and in the simplified minimal supersymmetric Standard Model. No significant deviations from Standard Model predictions are ob.erved.

A search for the direct production of the supersymmetric partners of τ-leptons (staus) in final states with two hadronically decaying τ-leptons is presented. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of 139 fb.1, recorded with the ATLAS detector at the Large Hadron Collider at a center-of-mass energy of 13 TeV. No significant deviation from the expected Standard Model b.ckground is ob.erved. Limits are derived in scenarios of direct production of stau pairs with each stau decaying into the stab.e lightest neutralino and one τ-lepton in simplified models where the two stau mass eigenstates are degenerate. Stau masses from 120 GeV to 390 GeV are excluded at 95% confidence level for a massless lightest neutralino.

Rapid development of metropolitan cities into smart cities and daily increased in numb.r of vehicles on the roads causes increase in traffic maintenance challenges such as traffic congestion, accidents, dispatching of emergency vehicle and pollution. It will suffers people travel time, delay in response time of emergency vehicle such as amb.lance, fire b.igade, police etc., causes heavy loss or effects society in terms of wealth, emotions and security. The research work done in the area of Intelligent Transportation Systems and Traffic Management primarily focuses on determining effectively green light duration along with dispatching of emergency vehicle. In this research paper, we propose an algorithm which not only determines green light duration dynamically b.t also handles the emergency vehicle management efficiently. The ob.ectives of the proposed algorithm are minimizing average waiting time. It always analysis the traffic situation at traffic intersection, along with continuous monitoring of emergency vehicle arrival at different lanes causes to optimize the waiting time of vehicle in lanes. It also deals with the deadlock and starvation condition, due to arrival of emergency vehicle in repeated interval of time in traffic intersection. The security level of emergency vehicle is in consideration during dispatching that assigned and verified b. authorities to preserve security measures and society values. Here, the source of input on dynamic traffic condition is collected through Wireless Sensor Networks technology.

A search is conducted for a low-mass charged Higgs b.son produced in a top quark decay and sub.equently decaying into a charm and a strange quark. The data sample was recorded in proton-proton collisions at s=13 TeV b. the CMS experiment at the LHC and corresponds to an integrated luminosity of 35.9 fb.1. The search is performed in the process of top quark pair production, where one top quark decays to a b.ttom quark and a charged Higgs b.son and the other to a b.ttom quark and a W b.son. With the W b.son decaying to a charged lepton (electron or muon) and a neutrino, the final state comprises an isolated lepton, missing transverse momentum, and at least four jets, of which two are tagged as b.jets. To enhance the search sensitivity, one of the jets originating from the charged Higgs b.son is required to satisfy a charm tagging selection. No significant excess b.yond standard model predictions is found in the dijet invariant mass distrib.tion. An upper limit in the range 1.68%–0.25% is set on the b.anching fraction of the top quark decay to the charged Higgs b.son and b.ttom quark for a charged Higgs b.son mass b.tween 80 and 160 GeV.

A search is describ.d for the production of a pair of b.ttom-type vectorlike quarks (VLQs), each decaying into a b.or b. quark and either a Higgs or a Z b.son, with a mass greater than 1000 GeV. The analysis is b.sed on data from proton-proton collisions at a 13 TeV center-of-mass energy recorded at the CERN LHC, corresponding to a total integrated luminosity of 137 fb.1. As the predominant decay modes of the Higgs and Z b.sons are to a pair of quarks, the analysis focuses on final states consisting of jets resulting from the six quarks produced in the events. Since the two jets produced in the decay of a highly Lorentz-b.osted Higgs or Z b.son can merge to form a single jet, nine independent analyses are performed, categorized b. the numb.r of ob.erved jets and the reconstructed event mode. No signal in excess of the expected b.ckground is ob.erved. Lower limits are set on the VLQ mass at 95% confidence level equal to 1570 GeV in the case where the VLQ decays exclusively to a b.quark and a Higgs b.son, 1390 GeV for when it decays exclusively to a b.quark and a Z b.son, and 1450 GeV for when it decays equally in these two modes. These limits represent significant improvements over the previously pub.ished VLQ limits.

Virtual Ob.ervatory (VO) is a world-wide ecosystem of mutually compatib.e datasets, resources, services, and software tools which use a common set of technologies and standards. SPLAT-VO is a leading stellar spectra analysis tool that allows displaying, modifying and analyzing astronomical spectra. SPLAT-VO also serves as a reference implementation of new VO protocols and data models and is b.ing enhanced in a way of interaction with other tools and collab.ration, as well as user experience. Our enhancements of SPLAT-VO allows to send large data sets received from VO data archives to other tools via SAMP protocol, export spectral data to b.g Data-friendly formats and to work with light curves in VOTab.e data cub. format. There is also a preview of other enhancements that significantly improves the user experience with large data sets and lowers the memory consumption of SPLAT-VO.

We present a measurement of the Hub.le constant H0 using the gravitational wave (GW) event GW190814, which resulted from the coalescence of a 23 M☉ b.ack hole with a 2.6 M☉ compact ob.ect, as a standard siren. No compelling electromagnetic counterpart with associated host galaxy has b.en identified for this event, thus our analysis accounts for ∼ 2,700 potential host galaxies within a statistical framework. The redshift information is ob.ained from the photometric redshift (photo-z) catalog from the Dark Energy Survey. The luminosity distance is provided b. the gravitational wave sky map pub.ished b. the LIGO/Virgo Collab.ration. Since this GW event has the second–smallest sky localization area after GW170817, GW190814 is likely to provide the b.st constraint on cosmology from a single standard siren without identifying an electromagnetic counterpart. Our analysis uses photo-z prob.b.lity distrib.tion functions and corrects for photo-z b.ases. We also reanalyze the b.nary–b.ack hole GW170814 within this updated framework. We explore how our findings impact the H0 constraints from GW170817, the only GW merger associated with a unique host galaxy, and therefore the most powerful standard siren to date. From a comb.nation of GW190814, GW170814 and GW170817, our analysis yields H0 = 69.0+−147.5 km s−1 Mpc−1 (68% Highest Density Interval, HDI) for a prior in H0 uniform b.tween [20,140] km s−1 Mpc−1. The addition of GW190814 and GW170814 to GW170817 improves the 68% HDI from GW170817 alone b. ∼ 12%, showing how well–localized mergers without counterparts can provide a marginal contrib.tion to standard siren measurements, provided that a complete galaxy catalog is availab.e at the location of the event.

Packet size optimization in WSN using LDPC codes

Packet size optimization in WSN using LDPC codes

In Wireless Sensor Networks energy (WSN) resources are limited. Most of the energy in a WSN is consumed in communication b.tween the sensor nodes. Packet size is one of the important parameter of the wireless communication. Larger packets have low energy consumption per b.t. However larger packets are less reliab.e. This paper studies packet size optimization in a WSN b.sed on energy throughput and reliab.lity metrics and analyzes the effect of using LDPC codes on energy efficiency. Our results show that LDPC codes can give larger optimal packet size and higher energy efficiency in comparison to no error control at higher prob.b.lity of b.t error rate.
