The mechanism for passive cochlear tuning remains unsettled. Early models considered the organ of Corti complex (OCC) as a succession of spring-mass resonators. Later, traveling wave models showed that passive tuning could arise through the interaction of cochlear fluid mass and OCC stiffness without local resonators. However, including enough OCC mass to produce local resonance enhanced the tu...

A lot of effort in Qualitative Reasoning had been spent in the RCC-8 calculus. This paper proposes a calculus named OCC (Occlusion Calculus) closely related to Galton’s LOS-14 calculus, that is more expressive in a vision context. The OCC relations qualitatively describe configurations from two convex objects in the projective view from a 3D scene. To set OCC on a mathematical ground an axiomat...

Clear cell adenocarcinoma of the ovary (OCC) is a chemo-resistant tumor with a relatively poor prognosis and is frequently associated with endometriosis. Although it is assumed that oxidative stress plays some role in the malignant transformation of this tumor, the characteristic molecular events leading to carcinogenesis remain unknown. In this study, an array-based comparative genomic hybridi...

The function of occludin (Occ) in the tight junction is undefined. To gain insight into its role in epithelial cell biology, occludin levels in Madin-Darby canine kidney II cells were suppressed by stably expressing short interfering RNA. Suppression of occludin was associated with a decrease in claudins-1 and -7 and an increase in claudins-3 and -4. Claudin-2 levels were unaffected. The tight ...

Distributed storage systems run transactions across machines to ensure serializability. Traditional protocols for distributed transactions are based on two-phase locking (2PL) or optimistic concurrency control (OCC). 2PL serializes transactions as soon as they conflict and OCC resorts to aborts, leaving many opportunities for concurrency on the table. This paper presents ROCOCO, a novel concurr...

Occludin is the first identified protein in the tight junction (TJ), but its function has remained for the most part obscure. TJs have been demonstrated to play important roles in the inner ear function, and occludin is expressed in all the epithelial TJs in the inner ear. Thus, we examined the inner ears of occludin-deficient (Occ(-/-)) mice. Although inner ears initially developed normally in...

The Optimistic Concurrency Control (OCC) method has been commonly used for in-memory databases to ensure transaction serializability — a transaction will be aborted if its read set has been changed during execution. This simple criterion to abort transactions causes a large proportion of false positives, leading to excessive transaction aborts. Transactions aborted false-positively (i.e. false ...

The results of this study indicate that the latency and silent periods of OCC cycles do not vary among groups representing distinct dentitional stages. The mean latency period durations obtained from the OCC cycles of the subjects in this study ranged from 16.6 to 19.5 msec and demonstrated the smallest SD of all parameters measured. The mean silent period durations ranged from 11.6 to 15.4 mse...
