How objects are held determines how they are seen, and may thereby play an important developmental role in building visual object representations. Previous research suggests that toddlers, like adults, show themselves a disproportionate number of planar object views - that is, views in which the objects' axes of elongation are perpendicular or parallel to the line of sight. Here, three experime...

In seeking a method for the routine observation of copulatory behaviour in rats we compared the use of a standard rectangular Makrolon cage, commonly used in toxicology studies, with a Plexiglas cylinder that provided 2.5 times more floor area. The cylinder resulted in a much higher incidence of copulation, either once or for multiple series, within 30 min. This was not affected by whether oest...

We show that Shannon’s information entropy provides a correct physical insight of localization effects taking place in structured fields fashioned by eigenmodes upon substrate. In particular, we find the exchange among levels when an avoided crossing occurs is explainable terms informational trade those levels. use it to characterize resonant Zener-like effect two types ultrasonic superlattices...

To determine the reliability of geometric (edge-detection) quantitative coronary angiographic analysis (QCA) of restenosis within a new Cordis tantalum stent, QCA and intracoronary ultrasound (ICUS) measurements were compared in both an experimental restenosis model and in the clinical follow-up of patients. In the experimental series, Plexiglas phantom vessels with concentric stenosis channels...

PURPOSE To evaluate in an in vitro model the feasibility and accuracy of Roentgen stereophotogrammetric analysis (RSA) versus computed tomography (CT) for the ability to detect stent-graft migration. METHODS An aortic model was constructed from a 22-mm-diameter Plexiglas tube with 6-mm polytetrafluoroethylene inlays to mimic the renal arteries. Six tantalum markers were placed in the wall of ...

In this study, dose rate distribution around a spherical 137Cs pellet source, from a low-dose-rate (LDR) Selectron remote afterloading system used in gynecological brachytherapy, has been determined using experimental and Monte Carlo simulation techniques. Monte Carlo simulations were performed using MCNP4C code, for a single pellet source in water medium and Plexiglas, and measurements were pe...

Lizards commonly climb in complex three-dimensional habitats, and gekkotans are particularly adept at doing this by using an intricate adhesive system involving setae on the ventral surface of their digits. However, it is not clear whether geckos always deploy their adhesive system, given that doing so may result in decreased (i.e. reduction in speed) locomotor performance. Here, we investigate...

In order to test the performance of new neutron thermal scattering law (TSL) evaluations it is desirable have experimental data that highly sensitive TSL and provides high fidelity information on energy dependent evaluations. Three relevant experiments are discussed including: accurate total cross section measurements, die-away experiments, leakage experiments. The setups results reviewed examp...

In this paper, a fully transparent antenna comprising of an Artificial Magnetic Conductor (AMC) backed Co-planar Waveguide (CPW) fed dual-ring monopole is presented. The and AMC structure achieve transparency due to the use AgHT-8 conductive oxide Plexiglas substrate. Measured performance shows impedance bandwidth 5.3 – 6 GHz (12.4%) in U-NII-1 U-NII-4 frequency band with peak gain 5.7 dBi whic...
