We propose a new thin and flat virtual reality (VR) display design using Fresnel lenslet array, lens, polarization-based optical folding technique. The proposed system has wide field of view (FOV) 102°x102°, eye-box 8.8 mm, an ergonomic eye-relief 20 mm. Simultaneously, only 3.3 mm physical distance is required between the panel so that integrated VR can have compact form factor like sunglasses...

Native topology correlates with folding rate: entangled topological relationships between protein loops facilitate folding. High numbers of topologically independent units (circuits) – normalized by size are associated fast kinetics.

BACKGROUND Endoderm organ primordia become specified between gastrulation and gut tube folding in Amniotes. Although the requirement for RA signaling for the development of a few individual endoderm organs has been established a systematic assessment of its activity along the entire antero-posterior axis has not been performed in this germ layer. METHODOLOGY/PRINCIPAL FINDINGS RA is synthesiz...

Ankylosing spondylitis (AS) is highly associated with the expression of human leukocyte antigen-B27 (HLA-B∗27). HLA-B∗27 heavy chain (B27-HC) has an intrinsic propensity to fold slowly, leading to the accumulation of the misfolded B27-HC in the endoplasmic reticulum (ER) and formation of the HLA-B∗27 HC homodimer, (B27-HC)2, by a disulfide linkage at Cys-67. (B27-HC)2 displayed on the cell surf...

The human prefrontal cortex has been considered different in several aspects and relatively enlarged compared to the rest of the cortical areas. Here we determine whether the white and gray matter of the prefrontal portion of the human cerebral cortex have similar or different cellular compositions relative to the rest of the cortical regions by applying the Isotropic Fractionator to analyze th...

We report multi-responsive and double-folding bilayer hydrogel sheet actuators, whose directional bending response is tuned by modulating the solvent quality and temperature and where locally crosslinked regions, induced by ionoprinting, enable the actuators to invert their bending axis. The sheets are made multi-responsive by combining two stimuli responsive gels that incur opposing and comple...

To compensate for the lack of abstraction in field origami, this paper, we propose a categorical description that can be introduced to map folding. Specifically, use particular expression abstract folding process with logical matrices. When operations are restricted two certain kinds, simple folds and unfolds, define categories partly folded states as poset categories. The property posets induc...
