Discovering heavy new physics in boosted Z channels: Z -> l(+)l(-) vs Z ->nu(nu)over-tilde
No full textWe propose a strategy for new physics searches in channels which contain a boosted Z boson and a boosted massive jet in the final state. Our proposal exploits the previously overlooked advantages of boosted Z -> nu(nu) over bar topologies, where collimated neutrinos result in signals with large missing energy. We illustrate the advantage of this channel in a case study of singly produced TeV scale charge 2/3 fermionic top partners (T') which decay to tZ final states. A comparison with the di-leptonic channel reveals that, despite the large t(t)over bar> background, signals with missing energy combined with jet substructure techniques offer superior probes of new physics at TeV scales. The effect can be attributed to a factor of similar to 3 enhancement in the signal cross section, coming from the branching ratio of Z -> nu(nu) over bar We exploit the unique event topology of singly produced top partners to suppress the t(t)over bar> background, as well as further improve on the existing proposals to detect T' in the boosted di-lepton channel. Our conclusions on advantages of Z -> nu(nu) over bar can be extended to most resonance searches which utilize a boosted Z boson in the final state10911Nsciescopu

Effects of transition metal in Sn-based pyrochlores on the methane catalytic combustion
No full textLanthanum stannate pyrochlores, La2Sn2O7 and La2SnMO7 (M=Mn, Fe, Co, Ni, Cu), were successfully prepared by citric acid method and confirmed by XRD. TG and TPR characterizations showed that the introduction of transitional metals resulted in significant impacts on the structures and redox performances of pyrochlores. All the selected transitional metals could significantly improve their methane catalytic combustion performance. Among the doped pyrochlores, La2SnCoO7 pyrochlore possessed optimum activities at low temperatures, and Fe-doped pyrochlore showed highest reactivity for high temperature combustion and was proved to be promising materials for high temperature catalytic combustion. The reactivity differences of La2SnMO7 were reasonably attributed to the strong interactions between Sn and transitional metal
Possible reduction of earthquake hazard on the Wellington Fault, New Zealand, after the nearby 1855, M 8.2 Wairarapa earthquake and implication for interpreting paleoearthquake intervals
No full textBased on the indicative modelling, the changes in Coulomb failure function (?CFS) suggest that the W-HV segment
and the T-P segment could be stable in at least the future 300 years and 190 years respectively, for these
periods should be needed to accumulate the stress released by the M 8.2 Wairarapa earthquake, assuming that
there is no influence from other sources, the earthquake did not alter the failure threshold, and that failure is a
fairly deterministic process. The results also show that the influence on the W-HV segment and T-P segment of
the Wellington Fault caused by the 1855, M 8.2 Wairarapa earthquake is significant considering that the average
fault rupture recurrence interval on the Wellington Fault is about 500-770 years. With our present understanding
of the Wellington and Wairarapa faults, it can be concluded that the 1855 Wairarapa earthquake retarded earthquake
occurrence on the W-HV segment and the T-P segment of the Wellington Fault. Thus the seismic hazard
in the Wellington region may be over-estimated.PublishedJCR Journalope
Z-valued T-norm and T-conorm Operators-based Aggregation of Partially Reliable Information
No full textAbstractT-norm and T-conorm operators are successfully used for processing uncertainty in system analysis, decision analysis, control, modeling and forecasting applications. The complexity of real-world applications is that relevant information is partially reliable. In this regard, Prof. L.A. Zadeh suggested the concept of a Z-number as an ordered pair Z1+Z2 of fuzzy numbers used to describe a value of a random variable X, where A is a fuzzy constraint on values of X and B is a fuzzy reliability of A, and is considered as a value of probability measure of R2. However, processing of Z-number based information is at its initial stage of crystallization. In this paper we consider Z-number valued T-norm and T-conorm operators of Z-numbers. A real-world application is used to illustrate validity and efficiency of Z-number valued T-norm and T-conorm operators based processing of partially reliable information
Landscape and Soil Erosion Changes Along Different Types of Road Over the Past 30 Years in the Largest Loess Tableland of China
No full textRoad construction, as a product of modern civilization, can alter landscape patterns and accelerate erosion, especially in the loess tableland area of China with fragile eco-environment. Different types of road could change land surface and increased soil erosion in different ways, while knowledge about this topic is limited. In this study, our objective is to evaluate the landscape and soil erosion changes along different types of road in the largest loess tableland of China. Results showed that: (1) The land use type became more diverse along the three types of road in 1990-2020, leading to increased landscape fragmentation and spatial heterogeneity. (2) Different types of road had different proportions of soil erosion values. In the expressway and provincial road, the proportion of low soil erosion values (below 100 t ha(-1) yr(-1)) was > 70% in 1990-2020; in the national road, the proportion of low erosion values (below 100 t ha(-1) yr(-1)) was > 50%. (3) In 1990-2020, soil erosion increased with the increase of road-induced landscape fragmentation along the three types of road. For the expressway, soil erosion value increased from 91.5 to 98.5 t ha(-1) yr(-1) between 1990 and 2020; for the national road, soil erosion value increased from 174.5 to 184.8 t ha(-1) yr(-1); and for the provincial road, soil erosion value increased from 93.7 to 97.1 t ha(-1) yr(-1). (4) Effective soil and water conservation programs could mitigate erosion. Compared with the simulated soil erosion value, the actual soil erosion value decreased along the expressway, national road, and provincial road by 1.21, 3.67, and 2.96 t ha(-1) yr(-1), respectively, between 2005 and 2020. This study emphasizes the importance of road in aggravating erosion and the effectiveness of soil and water conservation programs in mitigating soil erosion within the loess area
Measurement of the and production cross sections in multilepton final states using 3.2 fb of collisions at = 13 TeV with the ATLAS detector

All figures including auxiliary figures are available at http://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/TOPQ-2015-22/International audienceA measurement of the and production cross sections in final states with either two same-charge muons, or three or four leptons (electrons or muons) is presented. The analysis uses a data sample of proton-proton collisions at TeV recorded with the ATLAS detector at the Large Hadron Collider in 2015, corresponding to a total integrated luminosity of 3.2 fb. The inclusive cross sections are extracted using likelihood fits to signal and control regions, resulting in pb and pb, in agreement with the Standard Model predictions
