Recent developments in video technology enable us to view wider field-of-view (FOV) images using wide flat-panel displays, as one would a television monitor. New video systems with high resolution beyond HDTV have been proposed, but it is not clear that their motion picture quality will be sufficient if traditional video system frame rates are used. In the assessment of picture quality, it is recommended to screen viewers' static visual acuity (SVA), but not their dynamic visual acuity (DVA). Furthermore, the methodology to measure the DVA appropriate for the participants in such an assessment of picture quality has not yet been clearly established. In this paper, we have studied, experimentally, the changes in DVA performance by looking at differences in DVA measurement conditions as the first step to establish the methodology. We successfully verified the improvement of DVA performance in binocular viewing compared to monocular viewing. We also looked at the differences in DVA performance as a function of viewing conditions, including eye rotation direction (nasal or temporal direction), shape of the visual target (a Landolt C or E chart), ocular dominance (dominant or non-dominant eye), and the anisotropy or the difference in target orientation of a laterally moving target. © 2006 IEEE.

An information processing unit and information processing method capable of performing a ground-state search of an Ising model having coefficients of arbitrary values regardless of restrictions on hardware or software is suggested. When a ground state of an original problem, which is an Ising model, or an approximate solution of that ground state is calculated as a solution of the original problem, one or more sub-problems which are Ising models are generated from the original problem and the information processing unit searches the ground state of each generated sub-problem and generates a solution of the original problem based on a solution of each sub-problem obtained from the search; and when types of coefficient values of an Ising model whose ground state can be searched are limited, sub-problems which are Ising models composed of the types of limited values of coefficients are generated.

Purpose: For most of the 20th century, students with visual impairments were placed in separate schools from their peers. With major advances in public policy, it is now more common that all students (regardless of such disabilities) be integrated within schools and in classrooms. Recent research demonstrates a lack of products to support the visually impaired in STEM (science, technology, engineering, and mathematics) classrooms, as schools today often rely on large print or curricular materials that cannot wholly convey information to students. This project will develop a platform to enrich STEM learning among students with (or without) visual impairments. Project Activities: After mock-ups are completed, prototypes of the multi-media learning applications (apps) will be developed. A user-interface will be designed to house the apps and the materials needed to implement the intervention. Next, programming code will be authored to integrate a haptic controller device with the platform to enable tactile sensory learning opportunities. To assess implementation feasibility, the usability of the technology, and to gather data on the promise of the product to support learning, the pilot study will follow 10 classrooms over two months. The classrooms will include a mixture of students with and without visual impairments. Half of the classrooms will use the product to supplement their normal science curriculum whereas the other half will serve as a business-as-usual comparison group. Research questions will address the ease of integration of the product within classrooms, whether visually impaired students have greater access to science data than typical practices, and whether students learn more from using the platform compared to those not using the product. Pre and post measures will address STEM topics.

This invention relates to a method for producing a protein of interest, comprising introducing a protein expression vector which comprises a gene fragment a gene fragment comprising a DNA encoding a protein of interest and a selectable marker gene and transposon sequences at both terminals of the gene fragment, into a suspension mammalian cell; integrating the gene fragment inserted between a pair of the transposon sequences, into a chromosome of the mammalian cell to obtain a mammalian cell capable of expressing the protein of interest; and suspension-culturing the mammalian cell; and a suspension mammalian cell capable of expressing the protein of interest.
