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 background 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.

WSN-Wireless sensor networks are greatly in focus for the researchers. The use of WSN is foreseen for bringing massive changes in data gathering, processing and broadcasting. One of the most central design concerns in WSN is energy consumption. Hierarchical routing protocols are best acknowledged in respect to energy efficiency. Mobility based clustering (MbC) provides fruitful packet delivery rate, reduced energy consumption and average control overhead and it can adapt easily to a highly mobile surroundings. This paper presents the hierarchical routing protocol MbC algorithm. The mobility of a sensor node is considered as main aspect in the network as it will consume more energy so the proposed energy efficient routing algorithm handles the mobility of the sensor nodes. The ob.ective of these routing protocols is not only to improve the network life time but also to reduce end to end delay, reduce packet loss and link management etc.

This paper describes how to construct a probability map using sparse representation and dictionary learning to indicate the probability of each optic disk pixel of belonging to the optic cup. This probability map will be used in the future as input to a method for automatically detecting glaucoma from color fundus images. The probability map was obtained constructing a model (using the bayes classifier) which takes into account texture information, by means of sparse representation and RLS-DLA dictionary learning technique, and intensity information. Several experiments on a private database are presented in this work. The results are compared with the segmentation made by specialists, highlighting the promising performance of this technique in difficult cases where the optic cup is barely visib.e.

A search is presented for a narrow resonance decaying to a pair of oppositely charged muons using s=13 TeV proton-proton collision data recorded at the LHC. In the 45–75 and 110–200 GeV resonance mass ranges, the search is based on conventional triggering and event reconstruction techniques. In the 11.5–45 GeV mass range, the search uses data collected with dimuon triggers with low transverse momentum thresholds, recorded at high rate by storing a reduced amount of trigger-level information. The data correspond to integrated luminosities of 137 and 96.6 fb−1 for conventional and high-rate triggering, respectively. No significant resonant peaks are ob.erved in the probed mass ranges. The search sets the most stringent constraints to date on a dark photon in the ∼30–75 and 110–200 GeV mass ranges.

A methodology is presented to predict yield loci of drawing steels with virtual mechanical tests using (i) the statistical ALAMeL crystal plasticity model (VeF software of KU Leuven) and (ii) an approach based on representative volume elements (RVe's) solved with a spectral numerical Fast Fourier Transform (FFT) technique (DAMASK software of MPIe). In the latter case, the RVe's are defined in the form of a regular mesh of grid points in 3D-space with a crystal orientation assigned to each grid point. The experimental texture is derived from XRD pole figure measurements. Only tensile curves in the rolling direction are used to calibrate the hardening model included in the crystal plasticity models. For an interstitial free steel the predictions are compared to experimental yield loci, as obtained from uniaxial tests, plane strain tests, shear tests and through-thickness compression tests. Analytical FACeT yield loci are calibrated to the crystal plasticity (CP) models and these are used in Fe simulations of a square cup deep drawing process, validated by experiments.

The polarizations of promptly produced χc1 and χc2 mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at s=8 TeV. The χc states are reconstructed via their radiative decays χc→J/ψγ, with the photons being measured through conversions to e+e−, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χc2 to χc1 yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ→μ+μ− decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are ob.erved to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum.

The first search for supersymmetry in events with an experimental signature of one soft, hadronically decaying τ lepton, one energetic jet from initial-state radiation, and large transverse momentum imbalance is presented. These event signatures are consistent with direct or indirect production of scalar τ leptons (τ˜) in supersymmetric models that exhibit coannihilation between the τ˜ and the lightest neutralino (χ˜10), and that could generate the ob.erved relic density of dark matter. The data correspond to an integrated luminosity of 77.2 fb−1 of proton-proton collisions at s=13 TeV collected with the CMS detector at the LHC in 2016 and 2017. The results are interpreted in a supersymmetric scenario with a small mass difference (Δm) between the chargino (χ˜1±) or next-to-lightest neutralino (χ˜20), and the χ˜10. The mass of the τ˜ is assumed to be the average of the χ˜1± and χ˜10 masses. The data are consistent with standard model background predictions. Upper limits at 95% confidence level are set on the sum of the χ˜1±, χ˜20, and τ˜ production cross sections for Δm(χ˜1±,χ˜10)=50 GeV, resulting in a lower limit of 290 GeV on the mass of the χ˜1±, which is the most stringent to date and surpasses the bounds from the LeP experiments.

Alkali-activated fly Ash (AAFA) manufactured with conventional thermal curing (85oC) shows comparative mechanical properties to Portland cement (PC) based system, demonstrating its potential as a future low-carbon and environmentally friendly alternative cementitious material. However, the environmental benefit which could have b.en achieved from the low carbon nature of AAFA is often offset by the higher energy consumption from thermal curing. Since microwave heating is usually considered as a low-energy and low-carbon heating method, some pilot attempts have b.en made in the literature to cure AAFA with domestic microwave ovens. However, due to the lack of control on the temperature and humidity in domestic microwave ovens, splashing of fresh AAFA pastes and microcracks of hardened AAFA are two main reasons causing the unsatisfactory performance of microwave cured AAFA. In this study, a custom-made microwave oven equipped with proportional-integral-derivative (PID) control was employed to cure AAFA samples. The microwave power was automatically regulated through the real-time temperature feedback from the fib.e bragg grating (FbG) sensor embedded in the AAFA sample. The microwave curing regime consisted of four curing stages at four different temperatures, namely 65oC, 85oC, 105oC and 125oC. The similar temperature profile was applied on the AAFA cured in a conventional thermal oven. Compressive strength, reaction products and microstructure of AAFA samples with two curing methods were examined by the analytical techniques of XRD, FTIR, NMR, MIP and SeM respectively. The results showed that AAFA under microwave curing exhibited higher compressive strength with less energy consumption than that under the conventional thermal curing. The microwave curing favoured the formation of Al-rich N-A-SH gel in AAFA and a more compacted microstructure. © 2016 International Committee of the SCMT conferences. All rights reserved.

In today's scenario, lots of real-time applications are encountered which includes numerous computations that have to be done in parallel in stipulated period of time. For such tasks single core processors cannot perform well even multiprocessors are not ab.e to, because traditionally, sequential models were used which ignore parallelism between the tasks. However, parallel models have the capability to parallelize specific segments of tasks, thereby leading to shorter response times as possib.e. In this paper, the prob.em of scheduling the real time, periodic, implicit deadline nested-parallel tasks on multi-core processors is discussed. Initially, a nested-parallel task model, which is synchronous in nature wherein each task consists of number of segments and each segment consists number of parallel or nested threads, is considered. After, a novel task disintegration technique that disintegrates each parallel or nested-parallel task into a set of sequential tasks is proposed. Here it is proved that the proposed task disintegration technique achieve a resource augmentation bound of 3.414 when scheduled disintegrated tasks using global eDF scheduling, which means, if any task set is feasib.e on m unit speed processors, it can be scheduled using proposed technique on m 3.414 times faster processors. © 2015 Ieee.
