Impedance characterization of dielectric horn antennas using FDTD

, 2002
In this paper, we perform a detailed study of the input impedance of dielectric horn antennas with a two conical plate transmission line as a launcher, using the finite-difference time-domain (FDTD) method.

Early stages of tooth development in the harbor porpoise Phocoena phocoena

The Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Bioerosion traces in bones reveal an increase in ethological diversity in the insect exploitation of carcasses in the late Triassic

The Anatomical Record, EarlyView.
Abstract This study presents the first detailed description of bioerosion traces produced by insects in bones from the Santa Cruz Sequence (early Carnian, Santa Maria Supersequence, Brazil). An array of traces is reported, consisting of notches, a tube, trails of grooves attributed to the ichnotaxon Osteocallis mandibulus and ornamented depressions ...

Arthroscopic Lateral Tibial Plateau Translation Correlates With Pivot‐Shift Severity in Anterior Cruciate Ligament‐Deficient Knees

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To quantify arthroscopic lateral tibial plateau (LTP) translation in anterior cruciate ligament (ACL)‐deficient knees using a standardized intraoperative protocol and to evaluate its association with pivot‐shift grade and lateral tibial slope, including its ability to discriminate high‐grade pivot‐shift.
