Sensitivity of quantitative symmetry measurement algorithms for convergent beam electron diffraction technique.

We investigate the sensitivity of symmetry quantification algorithms based on the profile R-factor (R) and the normalized cross-correlation (NCC) coefficient (γ). A DM (Digital Micrograph) script embedded in the Gatan digital microscopy software is used to develop the symmetry quantification program. Using the Bloch method, a variety of CBED patterns are simulated and used to investigate the sensitivity of symmetry quantification algorithms.

An Ultrasonic Multi-Beam Concentration Meter with a Neuro-Fuzzy Algorithm for Water Treatment Plants.

Ultrasonic concentration meters have widely been used at water purification, sewage treatment and waste water treatment plants to sort and transfer high concentration sludges and to control the amount of chemical dosage. When an unusual substance is contained in the sludge, however, the attenuation of ultrasonic waves could be increased or not be transmitted to the receiver. In this case, the value measured by a concentration meter is higher than the actual density value or vibration.

Superficial mastoid fascia as an accessible donor for various augmentations in Asian rhinoplasty.

This study was designed to assess the anatomic characteristics and clinical versatility of superficial mastoid fascia as a soft-tissue donor for augmentation in Asian rhinoplasty. Dissections were performed on four fresh cadavers (eight ears) for histologic study. A 3×10 mm2-sized full layer of skin and underlying soft tissue was harvested from the postauricular area, transversely and longitudinally (cephalic and caudal directions), 5 mm apart from the midpoint of the auriculocephalic sulcus.

An update on auricular reconstruction: three major auricular malformations of microtia, prominent ear and cryptotia.

Purpose Of Review: Microtia, prominent ear, and cryptotia are the most common types of auricular malformations. This review provides updated information on these types of reconstructions, in addition to recalling previously accepted surgical methods.

Recent Findings: Autogenous costal cartilage is still considered as an ideal material for framework fabrication in microtia reconstruction.
