Purpose We investigated the effect of graded range of horizontal duction on the shape of the peripapillary Bruch's membrane (ppBM) and optic nerve head (ONH). Methods In 50 eyes of 25 normal subjects, the ONH and peripapillary retina were imaged by optical coherence tomography (OCT) in central gaze and incremental angles of add- and abduction. Displacements of the Bruch's membrane opening (BM...

Abstract The use of dead reckoning and fingerprint matching for navigation is a widespread technical method. However, mismatching low fusion accuracy are prevalent issues in indoor systems. This work presents an improved dynamic time warping chicken particle filter to handle these two challenges. To generate the Horizontal Vertical (HV) fingerprint, pitch roll employed instead original intensit...

Methods Front and back digital photographs of patients with idiopathic scoliosis (Cobb>25o) were obtained. Shoulder, armpit and waist angles, in addition to trunk asymmetry indexes, were calculated on front and back photographs with Surgimap software. On AP radiographs Coronal Cobb angles and radiological shoulder imbalance using CRIA angle (Angle between horizontal line and a line drawn betwee...

BACKGROUND Cam impingement as a known sequelae of slipped capital femoral epiphysis (SCFE) has led to speculation that subclinical SCFEs may be the causative factor in idiopathic cam morphology; alternatively, others have implicated an abnormal extension of the growth plate as a causative factor. HYPOTHESIS/PURPOSE To investigate the growth plate tilt angle in 4 patient cohorts: normal patien...

Recent advancements in renewable generation resources and their vast implementation power sectors have posed serious challenges regarding operation, protection, control. Maintaining operating frequency at its nominal value reducing tie-line deviations represent crucial factors for these due to continuous reduction of system inertia. In this paper, a new modified load controller (LFC) method is ...

background: to determine the most important preoperative factors that affect postoperative coronal parameters of scoliotic curves.   methods: all adolescent idiopathic scoliosis (ais) patients included in the study were classified according to lenke and king classification. the fusion levels were selected according to the rigidity of the existing curves (correction less than 50%), tilt of t1 an...

OBJECTIVES To evaluate the relationship between Trendelenburg tilt and internal jugular vein (IJV) diameter, and to examine any cumulative effects of tilt on the IJV diameter. METHODS Using a tilt table, healthy volunteers were randomised to Trendelenburg tilts of 10 degrees, 15 degrees, 20 degrees, 25 degrees, and 30 degrees. Ultrasound was used to measure and record the lateral diameter of ...

During surgical laparoscopy, total hepatic blood flow (THBF) may be modified by CO2insufflation, changes of tilt, ventilation with high tidal volume, hypercapnia, and anesthesia, but little information is available on the THBF during the procedure. To investigate the changes of hepatic blood flow following the combination of abdominal CO2 insufflation and changes of tilt, we measured mean arter...
