Abstract Origami tessellations can be folded from a given planar pattern into three-dimensional object with specific geometric properties, inspiring developments in various fields of science and engineering such as deployable structures, energy absorption devices, reconfigurable robots, metamaterials. However, the range existing origami patterns functional properties flat-foldability is rather ...

We explore the following problem: given a collection of creases on a piece of paper, each assigned a folding direction of mountain or valley, is there a flat folding by a sequence of simple folds? There are several models of simple folds; the simplest one-layer simple fold rotates a portion of paper about a crease in the paper by ±180◦. We first consider the analogous questions in one dimension...

This paper builds upon the fundamental paper by Niwa et al. [33] that provides the unique possibility to analyze the relative aggregation/folding propensity of the elements of the entire Escherichia coli (E. coli) proteome in a cell-free standardized microenvironment. The hardness of the problem comes from the superposition between the driving forces of intraand inter-molecule interactions and ...

AIMS To assess the influence of glistenings on the optical quality of acrylic foldable intraocular lens. METHODS Several degrees of glistenings in the optic were experimentally created by immersing the lens in water at 37 degrees C for 48 hours and then at 25 degrees C for 24 hours. Optical bench tests were carried out in water including measurements of spectral transmittance with the spectro...

AIM To compare the intraoperative difficulty and postoperative outcome in patients who have white mature cataract in one eye and other types of senile cataract in the other eye undergoing clear corneal phacoemulsification and foldable intraocular lens implantation. METHODS 82 patients who had white mature cataract in one eye, posterior subcapsular, cortical, nuclear, or mixed type cataract in...

Free-standing, highly flexible and foldable supercapacitor electrodes were fabricated through the spray-coating assisted layer-by-layer assembly of Ti3C2Tx (MXene) nanoflakes together with multi-walled carbon nanotubes (MWCNTs) on electrospun polycaprolactone (PCL) fiber networks. The open structure of the PCL network and the use of MWCNTs as spacers not only limit the restacking of Ti3C2Tx fla...

PURPOSE To compare the cost and outcomes of bilateral cataract surgery with the foldable AMOArray multifocal intraocular lens (MIOL) versus the foldable monofocal intraocular lens from the health care payer perspective. METHODS A cost-effectiveness analysis was used to evaluate treatment with the MIOL compared to monofocal lens, using data from clinical trials, literature, expert opinion, and...

The Conceptual design and Embodiment design are two of the important stages in a typical product design and development process. This study aims at generating different concepts for a foldable bicycle product using a systematic concept generation method and the best generated concepts have been selected using various concept selection methods. It also describes a systemic approach to material s...

1. Abstract This research develops a new structural optimization method for foldable motion structure with repeated rigid-body mechanism cell. Compared with conventional rigid-body mechanism, there are many kinematic advantages of a motion structure as it can achieve large shape transformation for real applications such as satellite solar panels, space antennas to shelters, and swimming pool co...

PURPOSE To evaluate the outcome for scleral fixation of a foldable acrylic intraocular lens (IOL) in aphakic post-pars plana vitrectomy eyes for vitreoretinal disease. METHODS The medical records of 15 patients were reviewed. We evaluated such factors as the underlying vitreoretinal disease, preoperative expected refraction and postoperative actual refraction, best corrected visual acuity (BC...
