BACKGROUND Even though oral cavity cancer (OCC; ICD 10 codes C01, C02, C03, C04, C05, and C06) ranks eleventh among the world's most common cancers, accounting for approximately 2 % of all cancers, a trend analysis of OCC in Hong Kong is lacking. Hong Kong has experienced rapid economic growth with socio-cultural and environmental change after the Second World War. This together with the collec...

This study was performed to investigate the significance of gastric juice analysis (GJA) as a diagnostic criterion of a positive challenge in a standard oral cow's milk challenge (OCC) to confirm typical cow's milk protein-induced enterocolitis (CMPIE). Data from 16 CMPIE patients (aged 14 to 44 days) were analyzed. A standard OCC was openly executed using 0.15 g/kg of protein. Three symptoms (...

The problem of dictionary matching is a classical problem in string matching: given a set S of d strings of total length n characters over an (not necessarily constant) alphabet of size σ, build a data structure so that we can match in a any text T all occurrences of strings belonging to S. The classical solution for this problem is the Aho-Corasick automaton which finds all occ occurrences in ...

The Open Cellular Convection (OCC) associated with cold air outbreaks is a common phenomenon over the North Sea where large number of wind parks are presented. Thus, reliable numerical simulations OCC events have great importance for offshore energy. We investigate ability to simulate using Weather Research and Forecast (WRF) model ERA5 reanalysis data as initial lateral boundary conditions OSI...

There is an ever-increasing demand for more complex transactions and higher throughputs in transaction processing systems leading to higher degrees of transaction concurrency and, hence, higher data contention. The conventional two-phase locking (2PL) Concurrency Control (CC) method may, therefore, restrict system throughput to levels inconsistent with the available processing capacity. This is...

Packing several characters into one computer word is a simple and natural way to compress the representation of a string and to speed up its processing. Exploiting this idea, we propose an index for a packed string, based on a sparse suffix tree [8] with appropriately defined suffix links. Assuming, under the standard unit-cost RAM model, that a word can store up to logσ n characters (σ the alp...

Although popular among computer scientists, the OCCmodel of emotions contains a number of ambiguities that stand in the way of a truthful formalization or implementation. This paper aims to identify and clarify several of these ambiguities. Furthermore, a new inheritance-based view of the logical structure of emotions of the OCC model is proposed and discussed.

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...

The polypeptide and structural gene for a high-molecular-mass c-type cytochrome, cytochrome c553O, was isolated from the methanotroph Methylococcus capsulatus Bath. Cytochrome c553O is a homodimer with a subunit molecular mass of 124,350 Da and an isoelectric point of 6. 0. The heme c concentration was estimated to be 8.2 +/- 0.4 mol of heme c per subunit. The electron paramagnetic resonance sp...
