A glass series [xSiO(2[-y])center dot 0.36ZnO center dot 0.17Na(2)O center dot 0.05CaO (starting at x = 0.50, y = 0.08 TiO2)] was formulated with TiO2 substituting SiO2. Each glass/silver-coated glass was characterized using X-ray diffraction, X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy. Surface area analysis revealed significant changes after silver coating, 0.43-0.95 m(2)/g (control), to 0.53-1.85 m(2)/g (AU-1), and 0.20-1.11 m(2)/g (AU-2). Ion release from uncoated glasses included sodium (0.08 mg/L), calcium (0.07 mg/L), and zinc (0.008 mg/L), where silver-coated glasses presented 0.42 mg/L (silver), 0.33 mg/L (sodium), 0.02 mg/L (calcium), and 0.01 mg/L (zinc). Ag-coated glasses presented inhibition zones of 7.75 mm (control) compared to 1.04 mm (AU-2).

Implementation and comparison of reconstruction algorithms for magnetic resonance-electric impedance tomography (mr-eit) Martin Lorca, Dario; Eyüboğlu, Behçet Murat; Department of Biomedical Engineering (2007) In magnetic resonance electrical impedance tomography (MR-EIT), crosssectional images of a conductivity distribution are reconstructed. When current is injected to a conductor, it generates a magnetic field, which can be measured by a magnetic resonance imaging (MRI) scanner. MR-EIT reconstruction algorithms can be grouped into two: current density based reconstruction algorithms (Type-I) and magnetic flux density based reconstruction algorithms (Type-II). The aim of this study is to implement a series of r...
A mechanism for the enhanced attachment and proliferation of fibroblasts on anodized 316L stainless steel with nano-pit arrays Ni, Siyu; Sun, Linlin; Ercan, Batur; Liu, Luting; Ziemer, Katherine; Webster, Thomas J. (Wiley, 2014-08-01) In this study, 316L stainless steel with tunable nanometer pit sizes (0, 25, 50, and 60 nm) were fabricated by an anodization procedure in an ethylene glycol electrolyte solution containing 5 vol % perchloric acid. The surface morphology and elemental composition of the 316L stainless steel were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), and X-ray photoelectron spectroscopy (XPS). The nano-pit arrays on all of the 316L stainless steel samples were in a regular arrang...
Measurement of differential and integrated fiducial cross sections for Higgs boson production in the four-lepton decay channel in pp collisions at root s=7 and 8 TeV Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2016-04-01) Integrated fiducial cross sections for the production of four leptons via the H -> 4l decays (l = e, mu) are measured in pp collisions at root s = 7 and 8TeV. Measurements are performed with data corresponding to integrated luminosities of 5.1 fb(-1) at 7TeV, and 19.7 fb(-1) at 8 TeV, collected with the CMS experiment at the LHC. Differential cross sections are measured using the 8 TeV data, and are determined as functions of the transverse momentum and rapidity of the four-lepton system, accompanying jet m...
Evaluation of multivariate adaptive non-parametric reduced-order model for solving the inverse electrocardiography problem: a simulation study Onak, Onder Nazim; Serinağaoğlu Doğrusöz, Yeşim; Weber, Gerhard Wilhelm (Springer Science and Business Media LLC, 2019-05-01) In the inverse electrocardiography (ECG) problem, the goal is to reconstruct the heart's electrical activity from multichannel body surface potentials and a mathematical model of the torso. Over the years, researchers have employed various approaches to solve this ill-posed problem including regularization, optimization, and statistical estimation. It is still a topic of interest especially for researchers and clinicians whose goal is to adopt this technique in clinical applications. Among the wide range of...
Parallel implementation of the accelerated BEM approach for EMSI of the human brain ATASEVEN, YOLDAŞ; Akalin-Acar, Z.; Acar, C. E.; Gençer, Nevzat Güneri (Springer Science and Business Media LLC, 2008-07-01) Boundary element method (BEM) is one of the numerical methods which is commonly used to solve the forward problem (FP) of electro-magnetic source imaging with realistic head geometries. Application of BEM generates large systems of linear equations with dense matrices. Generation and solution of these matrix equations are time and memory consuming. This study presents a relatively cheap and effective solution for parallel implementation of the BEM to reduce the processing times to clinically acceptable valu...
