Background. Fish species may be identified based on their unique otolith shape or contour. Several pattern recognition methods have been proposed to classify fish species through morphological features of the otolith contours. However, there has been no fully-automated species identification model with the accuracy higher than 80%. The purpose of the current study is to develop a fully-automate...

The ultrathin sections of the developing otolith of mouse fetuses 15.5 days to 20 days after birth were observed with the aid of the electron microscope. The first step of otolith formation is an aggregation of organic clusters observed in the sacculus of the 15.5-day fetus. These organic structures are modified and assume a hexagonal shape in the 17.5-day fetus. The unmineralized stages of the...

Relationships between fish length and otolith length, width mass were examined in the Australian anchovy Engraulis australis (White, 1790) recovered from food of Gannet colonies at islands Horuhoru Rock Mahuki Islands Hauraki Gulf, New Zealand. The relationships length- total (TL), otolith-weight-TL, otolith-width-TL investigated by means non-linear regression models (TL = 0.54 OL 16.86, TL 4.3...

Drawing on a panel study of parents and children, we investigate linkages between parents' marital quality and adult children's attitudes toward a range of family issues, including premarital sex, cohabitation, lifelong singlehood, and divorce. We hypothesize that parents' marital quality will be negatively related to children's support for these behaviors in adulthood and that parents' marital...

Understanding the functional linkages between the pelagic and demersal stages of marine organisms is a central goal in ecology. To better understand events that occurred during the larval period as well as their initial influence on juvenile traits, we examined individual level variation in early life-history traits (larval and early juvenile otolith growth rates, size-at-age, and larval durati...

Analysis of the shape properties of fish otolith is one way to identify stocks of different species in the marine environment. Length, width, area, perimeter, form factor, aspect ratio, roundness, circularity, ellipticity and rectangularity analyses of otoliths were undertaken to assess patterns of spatial and temporal stock structure of a wide-ranging fish, the Arabian yellow fin sea bream Aca...

The GEM muon system [1] is designed to achieve high momentum resolution by precisely measuring muon trajectories at three equidistant superlayers separated by a long lever arm in a large magnetized volume. In order to retain the desired precision at high momentum (i.e. ∆pt/pt ≈ 5% for the barrel detector at pt = 500 GeV/c), the muon system must determine the net 3-point sagitta of a muon track ...

Recent studies by Diamond and Markham have identified significant correlations between space motion sickness susceptibility and measures of disconjugate torsional eye movements recorded during parabolic flights. These results support an earlier proposal by von Baumgarten and Thumler which hypothesized that an asymmetry of otolith function between the two ears is the cause of space motion sickn...

Current concepts postulate a decisive role of the cerebellar nodulus in the processing of otolith input. We hypothesized that nodular lesions abolish otolith-perceptual integration, predicting alignment of perceived direction of earth vertical with the z-axis of the head and not with gravity. In an 80-year-old patient with acute heminodular infarction, the subjective visual vertical deviated co...

Inflight and post-landing "immunity" to the "coriolis sickness susceptibility test", observed during the Skylab M131 experiment, suggests that the otolith organs play a major role in space motion sickness (SMS). This view is supported by the report that ocular counter-torsion asymmetries correlate with SMS incidence and severity. Further data indicate that sensory-motor adaptation to microgravi...
