In this paper, we address a method for supporting origami folding process on origami. We focus on a folding operation with a view to understanding the state of origami. We estimate the folding operations by using one camera. The folding operation can be estimated by comparing origami shapes of before and after a folding operation. A silhouette model is introduced to grasp the correspondence of ...

We propose a new model for the alignment of fibrillin molecules within fibrillin microfibrils. Automated electron tomography was used to generate three-dimensional microfibril reconstructions to 18.6-A resolution, which revealed many new organizational details of untensioned microfibrils, including heart-shaped beads from which two arms emerge, and interbead diameter variation. Antibody epitope...

We investigated the impact of hydrodynamic interactions (HI) on protein folding using a coarse-grained model. The extent of the impact of hydrodynamic interactions, whether it accelerates, retards, or has no effect on protein folding, has been controversial. Together with a theoretical framework of the energy landscape theory (ELT) for protein folding that describes the dynamics of the collecti...

The pattern of angular correlations of hadrons with a (semi-)hard trigger hadron in heavy-ion collisions has attracted considerable interest. In particular, unexpected large angle structures on the away side (opposite to the trigger) have been found. Several explanations have been brought forward, among them Mach shockwaves and Cherenkov radiation. Most of these scenarios are characterized by r...

Two types of rod-coil block copolymers including poly(3-hexylthiophene)-block-poly(ethylene glycol) (P3HT-b-PEG) and PEG-block-polyaniline (PANI) were synthesized using Grignard metathesis polymerization, Suzuki coupling, and interfacial polymerization. Afterward, two types of single crystals were grown by self-seeding methodology to investigate the coily and rod blocks in grafted brushes and o...

We introduce an autonomous laser kirigami technique, a novel custom manufacturing machine system which functions somewhat similar to photocopier. This technique is capable of creating functional freeform shell structures using cutting and folding (kirigami) operations on sheet precursors. Conventional techniques are operated manually rely heavily precise calibrations. However, it unrealistic de...

In this paper, we suggest a novel transmission for the DC motor-based flapping-wing micro aerial vehicles (FWMAVs). Most FWMAVs employ linkage structures, such as crank-rocker or crank-slider, which are designed to transmit motor’s rotating motion wing’s flapping motion. These transmitting linkages have shown successful performance; however, they entail possibility of mechanical wear originatin...
