Intensive surveys have been conducted to unravel spatial patterns of benthic infauna communities. Although it has been recognized that benthic organisms are spatially structured along the horizontal and vertical dimensions of the sediment, little is known on how these two dimensions interact with each other. In this study we investigated the interdependence between the vertical and horizontal d...

We present an electrostatic microelectromechanical systems (MEMS) resonant scanner with large out-of-plane translational stroke for fast axial-scanning in a multi-photon microscope system for real-time vertical cross-sectional imaging. The scanner has a compact footprint with dimensions of 2.1 mm × 2.1 mm × 0.44 mm, and employs a novel lever-based compliant mechanism to enable large vertical di...

PURPOSE The aim of this randomized, controlled, blinded clinical study was to compare ridge dimensions and histologic characteristics of ridges preserved with 2 different graft materials. MATERIALS AND METHODS Twenty-four subjects, each requiring a nonmolar extraction and delayed implant placement, were randomly selected to receive ridge preservation treatment with either an allograft in an e...

We analyzed the variability in position, shape, size and incidence of the infraorbital foramen in Indian dry skulls as little literature is available on this foramen in Indians to prevent clinical complications during maxillofacial surgery and regional block anesthesia. Fifty-five Indian skulls from the Department of Anatomy CSM Medical University were examined. The 110 sides (left and right) o...

Perception of movement in acoustic space depends on comparison of the sound waveforms reaching the two ears (binaural cues) as well as spectrotemporal analysis of the waveform at each ear (monaural cues). The relative importance of these two cues is different for perception of vertical or horizontal motion, with spectrotemporal analysis likely to be more important for perceiving vertical shifts...

This paper examines a monopoly platform’s strategy in offering subsidies based on a microfoundation of trades on the two-sided platform. A key feature is the endogenous network effects that arise from sellers’ and buyers’ entry and trading decisions. The model also captures both horizontal and vertical dimensions of product differentiation, which directly affect these decisions. The results ill...

Microstructure and thermal evolution of sea-ice brine inclusions were investigated with magnetic resonance imaging Ž . 1 MRI techniques. Ice samples were kept at temperatures between y28C and y258C during H imaging in a 4.7-T magnet Ž at 200 MHz. Measurements were completed in a 20-cm diameter cylindrical probe and actively shielded gradient coils max. y1 . 50 mT m , pixel dimensions )0.2 mm, s...

The purpose of this in vivo study was to determine maximum and functional forces simultaneously in three dimensions on mandibular implants supporting overdentures. The anchorage system for overdenture connection was the ball-shaped retentive anchor. Five edentulous patients, each with two mandibular ITI implants, were selected as test subjects. A novel miniaturized piezo-electric force transduc...
