Symbolic play among children with autism spectrum disorder: a scoping review

2021

Symbolic play is considered an early indicator in the diagnosis of autism spectrum disorder (ASD) and its assessment. The objective of this study was to analyze the difficulties in symbolic play experienced by children with ASD and to determine the existence of differences in symbolic play among children with ASD, children with other neurodevelopmental disorders and children with typical development. A scoping review was carried out in the Web of Science (WoS), Scopus, ERIC, and PsycInfo databases, following the extension for scoping reviews of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The number of papers included in the review was 22. The r…

A novel putative insect chitinase with multiple catalytic domains: hormonal regulation during metamorphosis

2002

0264-6021 (Print) Journal Article Research Support, Non-U.S. Gov't; We have used differential display to identify genes that are regulated by juvenile hormone in the epidermis of the beetle Tenebrio molitor. One of the genes encodes T. molitor chitinase 5 (TmChit5), a chitinase possessing an unusual structure. Sequence analysis of TmChit5 identified five 'chitinase units' of approx. 480 amino acids with similarity to chitinase family 18. These units are separated by less conserved regions containing putative PEST (rich in proline, glutamic acid, serine and threonine) sequences, putative chitin-binding domains and mucin domains. Northern-blot analysis identified a single transcript of approx…

Developments in the use of baculoviruses for the surface display of complex eukaryotic proteins

2001

The ability to couple genotype to phenotype has proven to be of immense value in systems such as phage display and has allowed genes encoding novel functions to be selected directly from complex libraries. However, the complexity of many eukaryotic proteins places a severe constraint on successful display in Escherichia coli. This restriction could be resolved if a eukaryotic virus could be similarly engineered for display purposes. Preliminary data have suggested that the baculovirus Autographa californica, a multiple nuclear polyhedrosis virus (AcMNPV) is a candidate for eukaryotic virus display because the insertion of peptides into the native virus coat protein, or the expression of for…

Integral Imaging Monitors with an Enlarged Viewing Angle

2015

Enlarging the horizontal viewing angle is an important feature of integral imaging monitors. Thus far, the horizontal viewing angle has been enlarged in different ways, such as by changing the size of the elemental images or by tilting the lens array in the capture and reconstruction stages. However, these methods are limited by the microlenses used in the capture stage and by the fact that the images obtained cannot be easily projected into different displays. In this study, we upgrade our previously reported method, called SPOC 2.0. In particular, our new approach, which can be called SPOC 2.1, enlarges the viewing angle by increasing the density of the elemental images in the horizontal …

Microscopic and macroscopic 3D imaging and display by integral imaging

2011

Integral imaging is a rising 3D imaging technique that can be considered the incoherent version of holography. In integral imaging the multiperspective information of 3D scenes is stored in a 2D picture. Such picture, composed by a set of elemental images, is obtained through a 2D array of microlenses. The elemental-images set can be used for many purposes. One is the display of 3D color scenes to audiences or much more than one person. Other is the 3D display, with full parallax, in personal monitors, like the screen of a smartphone, a tablet, or the monitor used by a surgeon in an endoscopic operation. Other important types of applications are connected with the topographic reconstruction…

Full-parallax immersive 3D display from depth-map cameras

2016

We exploit two different versions of the Kinect to make comparison of three-dimensional (3D) scenes displayed by proposed integral imaging (InI) display system. We attempt to show the difference between each version specifications and capacity. Furthermore, we illustrate our study result with some empirical imaging experiment in which the final result are displayed with full-parallax. Each demonstrated integral images can provide clear comparison results to the observer.

Extended View Angle Integral Imaging 3D Display using Smart Pseudoscopic-to-orthoscopic Conversion with Head Tracking

2016

We overview a head tracking integral imaging display using the smart pseudoscopic-to-orthoscopic conversion method. The crosstalk for a large viewing angle in integral imaging is eliminated by generating a new set of elemental images.

Full parallax three-dimensional display from Kinect v1 and v2

2016

We exploit the two different versions of Kinect, v1 and v2, for the calculation of microimages projected onto integral-imaging displays. Our approach is based on composing a three-dimensional (3-D) point cloud from a captured depth map and RGB information. These fused 3-D maps permit to generate an integral image after projecting the information through a virtual pinhole array. In our analysis, we take into account that each of the Kinect devices has its own inherent capacities and individualities. We illustrate our analysis with some imaging experiments, provide the distinctive differences between the two Kinect devices, and finally conclude that Kinect v2 allows the display of 3-D images …
