We have recently observed and simulated confined acoustic phonons in both thin silicon-on insulator films and in SOI membranes [1]. Since progress in silicon device technology is going through increasing use of silicon-on-insulator (SOI) as a strategic device material to increase the operation speed of integrated circuits [2] modifications in the phonon spectrum are of strategic interest to dev...

OBJECTIVE Patient-derived organoids (PDOs), used in multiple tumor types, have allowed evaluation of tumor characteristics from individual patients. This study aimed to assess the feasibility of applying PDO in vitro culture for endocrine-based and drug sensitivity testing in endometrial cancer. METHODS Endometrial cancer cells were enzymatically dissociated from tumors retrieved from fresh h...

Mechanistic assessments based on kinetic and isotopic methods combined with density functional theory are used to probe the diverse pathways by which C-H bonds in CH4 react on bare Pd clusters, Pd cluster surfaces saturated with chemisorbed oxygen (O*), and PdO clusters. C-H activation routes change from oxidative addition to H-abstraction and then to σ-bond metathesis with increasing O-content...

The electrochemical oxidation behavior of m-nitrophenol (m-NP) was studied comparatively on glassy carbon electrode, Pt electrode, PbO2 electrode, SnO2 electrode, and graphite electrode using cyclic voltammetry. The cyclic voltammetry measurements were performed in acidic (1 M H2SO4, pH 0.4), neutral (1 M Na2SO4, pH 6.8), and...

A 4 · 4 strictly nonblocking thermo-optical switch matrix based on Mach–Zehnder (MZ) switching unit was designed and fabricated in silicon-on-insulator (SOI) wafer. The paired multi-mode interferometers (MMI) were used as power splitters and combiners in MZ structures. The device presents an average insertion loss of 17 dB and an average crosstalk of 16.5 dB. The power consumption needed for op...

In this paper, the implementation and characterization of high-sensitivity in-plane capacitive micro-gravity silicon-on-insulator (SOI) accelerometers with the readout circuitry are presented. The devices were implemented in 50 μm thick SOI substrates using a two-mask dry-release process. The fabricated accelerometers were interfaced to a low-noise low-power reference-capacitor-less switched-ca...

This paper is essentially a specification on analytical framework of a PhD thesis. The thesis itself is entitled: “Intellectual capital and economic performance of firms in the knowledge-based economy: a close look at evolution of modern enterprises” and is a study that seeks to understand the nature and function of the business firm as it is evolving with the changing today economy. The first ...

Abstract Flow prediction is regarded as a major computational process in strategic water resources planning. Prediction’s lead time has an inverse relationship with results’ accuracy and certainty. This research studies the impact of climate-atmospheric indices on surface runoff predictions long time. To this end, correlation 36 long-distance climate was examined at 10 key nodes Great Karun mul...

The southern oscillation index (SOI) is a characteristic of the El Niño phenomenon. SOI monthly averaged data is analyzed for the time interval 1866-2000. The tail of the cumulative distribution of the fluctuations of SOI signal is studied in order to characterize the amplitude scaling of the fluctuations and the occurrence of extreme events. Large fluctuations are more likely to occur than the...
