--High-performance digital circuits with aggressive timing constraints are usually very susceptible to delay faults. Much research done on delay fault detection needs a rather complicated test setup together with precise test clock requirements. In this paper, we propose a test technique based on the digital oscillation test method. The technique, which was simulated in software, consists of se...

The damping sensitivity analysis of interconnected power system low frequency oscillation is studied. The function of sensitivity analysis is implemented in the Small Signal Stability Analysis Package (SSAP). The paper mainly analyzes the sensitivities of oscillation modes with respect to the parameters of power system stabilizer (PSS) in the excitation systems of generators for a physical larg...

An oscillation with a period of around 500 kb in guanine and cytosine content (GC%) is observed in the DNA sequence of human chromosome 21. This oscillation is localized in the rightmost one-eighth region of the chromosome, from 43.5 Mb to 46.5 Mb. Five cycles of oscillation are observed in this region with six GC-rich peaks and five GC-poor valleys. The GC-poor valleys comprise regions with lo...

There remains considerable uncertainty about the underlying causes and functional significance of cortical oscillation and synchronization. We examined the temporal structure and synchronization of spikes in cell assemblies (groups of 4-6 cells with similar orientation preference). Recordings were made with a 5x5 microelectrode array in supragranular layers of Area 17 of cats paralyzed and anes...

The activated transcription factor NF-κB shuttles between the cytoplasm and the nucleus resulting in the oscillation of nuclear NF-κB (NF-κBn). The oscillation pattern of NF-κBn is implicated in the regulation of gene expression profiles. Using computational models, we previously reported that spatial parameters, such as the diffusion coefficient, nuclear to cytoplasmic volume ratio, transport ...

In this paper, the electronic eigenstates and energy spectra of single and two-interacting electrons confined in a concentric double quantum rings with a perpendicular magnetic field in the presence of         on-center donor and acceptor impurities are calculated using the exact diagonalization method. For a single electron case, the binding energy of on-center donor and acceptor impurities ar...

In a hydroelectric power plant or in a pumping station in order to avoid sudden large increase of pressure due to instantaneous valve closure sometimes a surge tank is installed. The height of surge tank is designed by the highest possible water level during the operation. The theoretical treatment of oscillation in a surge tank is difficult because of the non-linearity of friction term in the ...

Summertime cloud-to-ground lightning strikes are responsible for the majority of wildfire ignitions across vast sections of the seasonally dry western United States. In this study, a strong connection between active phases of the Madden–Julian oscillation (MJO) and regional summertime lightning activity was found across the interior western United States. This intraseasonal mode of lightning ac...

The larynges of nine squirrel monkeys were harvested, dissected, mounted on a tapered pseudotracheal tube, and phonated using heated and humidified air. The patterns of oscillation of the vocal folds were videotaped with stroboscopic illumination, and simultaneous measurements of airflow, subglottal pressure, and audio signal were obtained. The pressure wave and audio signal were subjected to s...

Recent theoretical claims not withstanding, muons can and do oscillate. Muons produced in association with neutrinos (if masses and mixing angles are nonzero) exhibit a joint oscillating spatial distribution. The possible use of muon oscillations as a probe of neutrino mass and mixing parameters is discussed using very simple physical arguments. Space-time oscillations in the secondary decay ve...
