2b or not 2b

Motivated by new physics models which lead to final states containing a high multiplicity of bottom and top quarks; we develop a tagging strategy to suppress reducible and non-reducible multi-jet backgrounds. The idea takes advantage of the properties of light parton showers and of the gluon fragmentation into heavy quarks to reject jets that do not originate from a bottom quark.Comment: 23 pages, 16 figure

Increasing the acceptance rate of H-\u3e 4e- Run 1 events by relaxing the applied cuts

The Decay mode of Higgs into four leptons allows for accurate parameter reconstruction and is thus a useful channel to research. The study attempted to increase the number of four electron events that pass selection cuts, without greatly increasing the amount of background noise, by varying the transverse momentum, invariant mass of the subleading electrons, and electron identification. With the application of a boosted decision tree targeting the ZZ* noise, the study found that the optimal configuration was a loose electron identification with the invariant mass greater than 10 GeV and the transverse momentum greater than 7 GeV

The Enhancement of Cooperative Ability and Becoming a Good Listener Ability in Solubility and Solubility Product by Learning of Hypnoteaching Method

The purpose of this research is to describe the effectiveness of improving the cooperative ability and becoming a good listener with using hypnoteaching in solubility and solubility product.The research was done in class XI IPA2 State Senior High School 13 Bandar Lampung. This study used a pre-experimental method with One Shoot Case Study Design. The effectiveness of hypnoteaching is measured by the percentage of average research finding in each meeting. After observation in five meetings, the average percentage of cooperative ability has improved significantly with percentage 44.85%, 50.00%, 61.25%, 63.53%, and 65.00%. Then, becoming a good listener with percentage 66.67%, 70.56%, 73.13%, 74.71%, and 81.11% has improved significantly too. Therefore, it can be concluded that learning with hypnoteaching is significant to improve cooperative ability and becoming a good listener

Late Pleistocene glaciations and catastrophic glacial floods of Central Colorado

Late Pleistocene glaciations of the Sawatch and Elk Mountain Ranges of Central Colorado at ~130 and ~20 ka left behind glacial features in the topography, ideal for constraining the local climactic variability. In the northern end of the Sawatch Range, distinct lateral and terminal moraines reveal strong geologic evidence that multiple large glaciers drained eastward. Two of these appear to have dammed the Arkansas River. Very fine-grained lacustrine sediments, &lsquo;ice-rafted&rsquo; boulders, and catastrophic glacial flood boulders down-valley, show at least two glacial-ice dammed lakes that catastrophically drained. We report flood discharge calculations consistent with previous estimates, on the order of ~50,000 m3/s. For this study, we employ a 1-D finite difference staggered-grid mass conservation numerical model to reconstruct paleoglacier extent and equilibrium line elevations. I prescribe a mass balance based on a scaled approximation of the marine &delta;18O record, with normally distributed random number generation. Modeled ELA&rsquo;s on the order of ~3400 m are consistent with temperature depressions nearly ~6 &ordm;C below the modern mean annual air temperature. Our model shows internal consistency with the dependence of catchment geometry and variable metrological forcing on glacier disequilibrium response time. In the West Elk Mountains lies Snowmass Creek Valley, where at ~20 ka the ice extent is required to have preserved the famous Ziegler Reservoir paleontological site. Employing our 1-D numerical model on this site, for the climate at ~20 ka, reveals that the required temperature depression is on the order of ~1&ordm;C warmer than it was during the Bull Lake glaciation at ~130 ka.</p

Pengaruh Elektrolit Terhadap Sinyal Pada Sensor Pestisida

Telah diteliti pengaruh elektrolit terhadap sinyal sensor pestisida menggunakan sensor diazinon dan sensor klorpirifos. Sensor menggunakan reseptor molecularly imprinted polymer (MIP) poli vinil alkohol (PVA)-Fe3O4. Komposisi reseptor MIP PVA-Fe3O4 untuk sensor diazinon adalah PVA 70,19 %; Fe3O4 1,72 %; glutaraldehid 12,48 %; asam sitrat 15,59 % dan diazinon 0,02 %. Komposisi reseptor MIP PVA-Fe3O4 untuk sensor klorpirifos adalah PVA 82,8 %; Fe3O4 0,5%; glutaraldehid 7,4 %; asam sitrat 9,2 % dan klorpirifos 0,1 %.

Aplikasi MIP Poli Vinil Alkohol (PVA)-Fe3O4 dalam Pengembangan Sensor Diazinon dan Monosodium Glutamat

Molecularly Imprinted Polymer (MIP) dari poli vinil alkohol (PVA)-Fe3O4 telah dikembangkan sebagai reseptor pada sensor kimia untuk diazinon dan monosodium glutamat (MSG). MIP dibuat dari PVA menggunakan glutaraldehid sebagai crosslinker dan asam sitrat sebagai katalis. Reseptor adalah suatu template yang disesuaikan dengan sensornya; template diazinon untuk sensor diazinon dan template MSG untuk sensor MSG. Reseptor MIP PVA-Fe3O4 dilapiskan pada permukaan elektroda karbon tipe screen printed (SPE). Pada penelitian ini, telah dipelajari pengaruh asam sitrat dan glutaraldehid terhadap pembentukan MIP. Dipelajari juga pengaruh kadar diazinon dan MSG terhadap kinerja masing-masing sensor. Kadar diazinon dalam reseptor yang dipelajari adalah 0,01; 0,02; dan 0,03%, sedangkan kadar MSG adalah 0,5; 0,9; dan 4,5%. Berdasarkan spektrum FTIR, hasil penelitian menunjukkan bahwa pada MIP PVA-glutaraldehid terdapat gugus fungsi C-O yang menunjukkan adanya ikatan silang antara PVA dan glutaraldehid; sedangkan pada MIP PVA-asam sitrat tidak menunjukkan adanya gugus fungsi tersebut. Kinerja sensor diazinon dan MSG dipengaruhi oleh kadar/jumlah template dalam reseptor. Kinerja optimum sensor dihasilkan pada membran reseptor masing-masing adalah diazinon 0,02 %, dan MSG 0,5 %. Kepekaan sensor diazinon adalah&nbsp; 33,8 mV/dekade pada pH 2, dalam buffer fosfat-KCl, rentang konsentrasi 10-5-10-12 M, dan waktu respon 150 detik. Kepekaan sensor MSG adalah 33,25 mV/dekade pada kisaran konsentrasi 10-5-10-1 M,&nbsp; dalam pH 5 dan waktu respon 180 detik
