TiN and (Ti,Mg)N thin film coatings were deposited on titanium substrates by using cathodic arc physical vapor deposition (arc-PVD) technique with magnesium contents of 0, 4.24 at% (low Mg) and 10.42 at% (high Mg). The presence of magnesium on both normal (hFOB) and cancer (SaOS-2) osteoblast cell behavior was investigated in (Ti, Mg) N surfaces with or without prior hydroxyapatite (HA) deposition (in simulated body fluid, SBF). Mg incorporation on TiN films was found to have no apparent effect on the cell ...

M.; Grossmann, J.; Hrubec, J.; Jeitler, M.; Koenig, A.; Krammer, N.; et.al. (Springer Science and Business Media LLC, 2017-11-01)
Results are reported from a search for physics beyond the standard model in proton-proton collision events with a charged lepton (electron or muon), two jets identi fi ed as originating from a bottom quark decay, and signi fi cant imbalance in the transverse momentum. The search was performed using a data sample corresponding to 35.9 fb(-1), collected by the CMS experiment in 2016 at root s = 13 TeV. Events with this signature can arise, for example, from the electroweak production of gauginos, which are pr...

Kayis-Topaksu, A; Onengut, G; van Dantzig, R; de Jong, A; Melzer, O; Oldeman, RGC; Pesen, E; Spada, FR; Visschers, JL; Guler, M; Kose, U; Serin-Zeyrek, A; Sever, R; Tolun, P; Zeyrek, Mehmet Tevfik; Armenise, N; Catanesi, MG; De Serio, M; Leva, M; et.al. (Elsevier BV, 2003-03-01)
A measurement of Lambda(c)(+) production in neutrino nucleon charged-current interactions is presented. In a subsample of about 50 000 interactions located in the emulsion target of the CHORUS detector, exposed to the wide band neutrino beam of the CERN SPS, candidates for decays of short-lived particles were identified using new automatic scanning systems and later confirmed through visual inspection. Criteria based on the flight length allowed a statistical separation among the different charm species thu...
Epistemic Injustice and Cultural Processes in Education
Göktürk Ağın, Duygun (2021-01-01)
This article provides a framework for understanding social and cultural inequalities in education in the context of cultural processes and epistemic injustice. Insight into the cultural processes and the concept of epistemic injustice direct us to the conceptualization of agency of the actors within the educational domain and the institutionalized relations of domination and recognition. The article employs two cultural processes: identification (stigmatization and racialization) and rationalization (st...

Chatrchyan, S.; Khachatryan, V.; Sirunyan, A. M.; Tumasyan, A.; Adam, W.; Bergauer, T.; Dragicevic, M.; Eroe, J.; Fabjan, C.; Friedl, M.; Fruehwirth, R.; Ghete, V. M.; Hammer, J.; Hoch, M.; Hoermann, N.; Hrubec, J.; Jeitler, M.; Kiesenhofer, W.; Krammer, M.; et.al. (IOP Publishing, 2012-10-01)
The performance of muon reconstruction, identification, and triggering in CMS has been studied using 40pb(-1) of data collected in pp collisions at root s = 7TeV at the LHC in 2010. A few benchmark sets of selection criteria covering a wide range of physics analysis needs have been examined. For all considered selections, the efficiency to reconstruct and identify a muon with a transverse momentum p(T) larger than a few GeV/c is above 95% over the whole region of pseudorapidity covered by the CMS muon syste...
Forecasting of Product Quality Through Anomaly Detection
Dinç, Mehmet; Ertekin Bolelli, Şeyda; Özkan, Hadi; Meydanlı, Can; Atalay, Mehmet Volkan (2020)
Forecasting of product quality by means of anomaly detection is crucial in real-world applications such as manufacturing systems. In manufacturing systems, the quality is assured through tests performed on sample units randomly chosen from a batch of manufactured units. One of the major issues is to detect defective units among the sample test units as early as possible in terms of test time and of course as accurate as possible. Traditional way of detecting defective units is to make use of human experts d...

A search for a standard model Higgs boson produced in association with a top-quark pair and decaying to bottom quarks is presented. Events with hadronic jets and one or two oppositely charged leptons are selected from a data sample corresponding to an integrated luminosity of 19.5 fb(-1) collected by the CMS experiment at the LHC in pp collisions at a centre-of-mass energy of 8 TeV. In order to separate the signal from the larger t (t) over bar + jets background, this analysis uses a matrix element method t...

Search regions are defined using the properties of reconstructed jets, the multiplicity of bottom and top quark candidates, and an imbalance in transverse momentum. With no statistically significant excess ...

Sirunyan, A. M.; Tumasyan, A.; Adam, W.; Ambrogi, F.; Asilar, E.; Bergauer, T.; Brandstetter, J.; Brondolin, E.; Dragicevic, M.; Eroe, J.; Del Valle, A. Escalante; Flechl, M.; Fruehwirth, R.; Ghete, V. M.; Hrubec, J.; Jeitler, M.; Krammer, N.; Kraetschmer, I; Liko, D.; et.al. (Elsevier BV, 2018-10-01)
A search for an exotic decay of the Higgs boson to a pair of light pseudoscalar bosons is performed for the first time in the final state with two b quarks and two tau leptons. The search is motivated in the context of models of physics beyond the standard model (SM), such as two Higgs doublet models extended with a complex scalar singlet (2HDM + S), which include the next-to-minimal supersymmetric SM (NMSSM). The results are based on a data set of proton-proton collisions corresponding to an integrated lum...

A search for groups of collimated muons is performed using a data sample collected by the CMS experiment at the LHC, at a centre-of-mass energy of 7TeV, and corresponding to an integrated luminosity of 35 pb(-1). The analysis searches for production of new low-mass states decaying into pairs of muons and is designed to achieve high sensitivity to a broad range of models predicting leptonic jet signatures. With no excess observed over the background expectation, upper limits on the production cross section t...

Sirunyan, A. M.; Tumasyan, A.; Adam, W.; Ambrogi, F.; Asilar, E.; Bergauer, T.; Brandstetter, J.; Brondolin, E.; Dragicevic, M.; Eroe, J.; Flechl, M.; Friedl, M.; Fruehwirth, R.; Ghete, V. M.; Grossmann, J.; Hrubec, J.; Jeitler, M.; Koenig, A.; Krammer, N.; et.al. (Elsevier BV, 2018-06-01)
Angular distributions of the decay B-0 -> K*(0)mu(+)mu(-) are studied using a sample of proton-proton collisions at root s = 8 TeV collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 20.5 fb(-1). An angular analysis is performed to determine the P-1 and P-5' parameters, where the P-5' parameter is of particular interest because of recent measurements that indicate a potential discrepancy with the standard model predictions. Based on a sample of 1397 signal events, the P-...
Precise mapping of the magnetic field in the CMS barrel yoke using cosmic rays
Chatrchyan, S.; Khachatryan, V.; Sirunyan, A. M.; Adam, W.; Arnold, B.; Bergauer, H.; Bergauer, T.; Dragicevic, M.; Eichberger, M.; Eroe, J.; Friedl, M.; Uhwirth, R. Fr; Ghete, V. M.; Hammer, J.; Haensel, S.; Hoch, M.; Hoermann, N.; Hrubec, J.; Jeitler, M.; et.al. (IOP Publishing, 2010-03-01)
The CMS detector is designed around a large 4 T superconducting solenoid, enclosed in a 12 000-tonne steel return yoke. A detailed map of the magnetic field is required for the accurate simulation and reconstruction of physics events in the CMS detector, not only in the inner tracking region inside the solenoid but also in the large and complex structure of the steel yoke, which is instrumented with muon chambers. Using a large sample of cosmic muon events collected by CMS in 2008, the field in the steel of...
