Purpose Shifting the region-of-interest within the input image to compensate for gaze shifts ("gaze compensation") may improve hand-eye coordination in visual prostheses that incorporate an external camera. The present study investigated the effects of eye movement on hand-eye coordination under simulated prosthetic vision (SPV), and measured the coordination benefits of gaze compensation. Me...

The completion of tensors, or high-order arrays, attracts significant attention in recent research. Current literature on tensor completion primarily focuses on recovery from a set of uniformly randomly measured entries, and the required number of measurements to achieve recovery is not guaranteed to be optimal. In addition, the implementation of some previous methods are NP-hard. In this artic...

Modeling of irrigation and agricultural drainage requires knowledge the soil hydraulic properties. However, uncertainty in direct measurement saturation moisture content (θs) has been generated several methodologies for its estimation, such as Pedotransfer Functions (PTFs) Artificial Neuronal Networks (ANNs). In this work, eight different PTFs were developed which relate to proportion sand clay...

PURPOSE The aim of this study was to evaluate a clinical test of hyperacuity in the assessment of retinal-neural function in patients with posterior capsular opacification. METHODS Neodymium (Nd):YAG laser capsulotomy was performed on 39 subjects (mean age, 76.72 years +/- 10.41 years). Measurements of refractive error, logMAR acuity, and displacement threshold hyperacuity (DTH) were made bef...

ID: 6000 Title: MRI Relaxometry BMD Measurements using Conventional Phase Symmetrized Rapid Increased Flip Spin Echo and Standard Gradient Echo and its correlation with DXA Purpose: Recently, several special MRI protocols have been developed for BMD measurements for deriving R2(=1/T2), R2*(=1/T2*) and R2'(=R2*-R2) applied in several cross sectional studies. But, due to high slew rate gradients ...

BACKGROUND Myotonic dystrophy type 1 (DM1) is a multisystem disorder that demonstrates variable symptoms and rates of progression. Muscle weakness is considered one of the main problems with a clinical picture that is characterized by distal weakness of the limbs progressing to proximal weakness. The main objective of this study was to characterize the maximal strength of ankle eversion and dor...

PURPOSE This study aimed to develop a new field test protocol with a standardized measurement of strength and power in plantar flexor muscles targeted to functionally independent older adults, the calf-raise senior (CRS) test, and also evaluate its reliability and validity. PATIENTS AND METHODS Forty-one subjects aged 65 years and older of both sexes participated in five different cross-secti...
