A search for low mass narrow vector resonances decaying into quark-antiquark pairs is presented. The analysis is based on data collected in 2017 with the CMS detector at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 41.1 fb−1. The results of this analysis are combined with those of an earlier analysis based on data collected at the same collision energy in 2016, corresponding to 35.9 fb−1. Signal candidates will be recoiling against initial state radiation and are identified as energetic, large-radius jets with two pronged substructure. The invariant jet mass spectrum is probed for a potential narrow peaking signal over a smoothly falling background. No evidence for such resonances is observed within the mass range of 50–450 GeV. Upper limits at the 95% confidence level are set on the coupling of narrow resonances to quarks, as a function of the resonance mass. For masses between 50 and 300 GeV these are the most sensitive limits to date. This analysis extends the earlier search to a mass range of 300–450 GeV, which is probed for the first time with jet substructure techniques.

Community based flood assessment is essential for flood hazard mapping because people know a great deal about their surroundings. Geographic Information System (GIS) and Community Participation are the approaches used to integrate modern technology and to incorporate the knowledge and opinions of rural people in flood hazard assessment. It discusses the flood reconnaissance survey as participated by the locals in the community in order to strengthen a good partnership between local government units, universities in the region and national institutions. The paper also shows flood prone areas in the local community using GIS and was validated using Focus Group Discussion (FGD) and Key Informant Interview (KII). Specifically, the study found out the flood coverage, height of flood, damages brought about by flood, probable cause of flood and other flood hazards encountered. Installation of rain gauge, deployment of digital current flow meter (DCFM) and depth gauge which were participated by community representatives were also presented in this paper. All of these findings and the use of LiDAR technology acquired by UP Diliman Data Acquisition Component are the requisites for the data needed in flood hazard mapping specifically presented through the case of Lipadas River in the province of Davao del Sur, Southern Mindanao, Region XI.

There are challenges of using composite laminates in the marine engineering, i.e., composites are frequently suffering from the effects of impaction including wave impaction, ship or other objects hitting, missiles or bullets hitting and other especially conditions. It is significant to understand the impact behaviors of laminates, in this research, the impact responses of typical laminates are investigated numerically. The delamination responses among the plies and fibre and/or matrix damage responses within the plies are simulated to understand the impaction behaviours of laminates under impaction conditions. The impact damage of composite laminates in the form of intra- and/or inter-laminar cracking is modelled by using stress-based criteria for damage initiation, and fracture mechanics technique is used to capture its evolution. Interface cohesive elements are inserted between plies with appropriate mixed-mode damage laws to predict the delamination. A group of graphite fibre/epoxy laminates with impact energies of 5, 10, 15 and 20 J, respectively, are simulated with a full scale FE model and a simplified FE model respectively. Through comparing the simulation results with each other, we find out that the impact behaviors obtained in the simplified FE model is comparable to experiments with a short computing time, but the simplified model cannot represent the properties of laminate after impact. © (2015) Trans Tech Publications, Switzerland.

Multiple recent neuroimaging studies revealed that functional interactions within brain regions are locally clustered into small sub-networks where different dynamics of functional interaction occur. However, integration models investigating such functional brain dynamics have been rarely explored. In this paper, a novel Bayesian inference model is developed to partition the brain regions into different sub networks and to simultaneously segment temporal sequence of each sub network into several quasi-stable blocks based on the interaction dynamics among regions. The proposed model has been evaluated and validated by two different simulation models. Also, the model has been applied to a working-memory task-based fMRI dataset and interesting results on both dynamic sub networks and change points were obtained. © 2015 IEEE.

This paper identifies the main criteria used by architecture specialists in the task of clustering alternative floor plan designs. It shows how collective actions of respondents lead to their clustering by carrying out an online exercise. The designs were randomly pre-generated by a hybrid evolutionary algorithm and a questionnaire was posed in the end for the respondents to indicate which similarity criteria they have used. A network of designs was then obtained and it was partitioned into clusters using a modularity optimization algorithm. The results show that the main criterion used was the internal arrangement of spaces, followed by overall shape and by external openings orientation. This work allows the future development of novel algorithms for automatic classification, clustering, and database retrieval of architectural floor plans. © Springer International Publishing Switzerland 2015.

A lot of Not Only SQL (NoSQL) databases have been proposed in the era of big data. Distributed Ordered Table (DOT) is one kind of No SQL database that has attracted lots of attention. It horizontally partitions table into regions and distributes regions to region servers according to the keys. Multi-Dimensional Range Query (MDRQ) is a common operation over DOTs. Many indexing techniques have been proposed to improve the performance of MDRQ, but they cannot guarantee high performance on both insert and flexible MDRQ at the same time. In this paper, we propose a novel indexing technique named LC Index, short for Local and Clustering Index, to solve this issue. Experimental results confirm that LC Index can achieve high performance on both insert operations and flexible MDRQ.

Data volume grows dramatically in the era of big data. To save capital cost on storage hardware, datacenters currently prefer using erasure coding rather than simply replication to resist data loss. Erasure coding can provide equivalent three-way fault tolerance to HDFS's default three replication mechanism but degrades data availability for task scheduling. In an erasure-coded system, data reconstruction time will be paid while tasks access the missing blocks during MapReduce job processing. Tasks' accessing corrupt data introduces task stragglers and degrades resource utilization. To overcome these challenges, we propose a novel mechanism, Dominoes, that coordinates lightweight data states checking and job scheduling to hide such recovery penalty during job processing and enhances job throughputs. The experimental results confirm Dominoes' effectiveness and efficiency that improves job throughput by 9% to 9.7% under failure at an overhead of 2.6% for failure-free jobs.

A search for astrophysical point-like neutrino sources using the data collected by the ANTARES detector between January 29, 2007 and December 31, 2017 is presented. A likelihood stacking method is used to assess the significance of an excess of muon neutrinos inducing track-like events in correlation with the location of a list of possible sources. Different sets of objects are tested in the analysis: a) a sub-sample of the Fermi 3LAC catalog of blazars, b) a jet-obscured AGN population, c) a sample of soft gamma-ray selected radio galaxies, d) a star-forming galaxy catalog, and e) a public sample of 56 very-high-energy track events from the IceCube experiment. None of the tested sources shows a significant association with the sample of neutrinos detected by ANTARES. The smallest p-value is obtained for the radio galaxies catalog with an equal weights hypothesis, with a pre-trial p-value equivalent to a 2.8 σ excess, equivalent to 1.6 σ post-trial. In addition, the results of a dedicated analysis for the blazar MG3 J225517+2409 are also reported: this source is found to be the most significant within the Fermi 3LAC sample, with 5 ANTARES events located at less than one degree from the source. This blazar showed evidence of flaring activity in Fermi data, in space-time coincidence with a high-energy track detected by IceCube. An a posteriori significance of 2.0 σ for the combination of ANTARES and IceCube data is reported. Copyright © 2020, The Authors. All rights reserved.

An offline search for a neutrino counterpart to gravitational-wave (GW) events detected during the second observation run (O2) of Advanced-LIGO and Advanced-Virgo performed with ANTARES data is presented. In addition to the search for long tracks induced by νµ (νµ) charged current interactions, a search for showering events induced by interactions of neutrinos of any flavour is conducted. The severe spatial and time coincidence provided by the gravitational-wave alert allows regions above the detector horizon to be probed, extending the ANTARES sensitivity over the entire sky. The results of this all-neutrino-flavour and all-sky time dependent analysis are presented. The search for prompt neutrino emission within ±500 s around the time of six GW events yields no neutrino counterparts. Upper limits on the neutrino spectral fluence and constraints isotropic energy radiated via high-energy neutrinos (from a few TeV to a few tens of PeV) are set for each GW event analysed.
