Origami structures enabled by folding and unfolding can create complex 3D shapes. However, even a small 3D shape can have large 2D unfoldings. The huge initial dimension of the 2D flattened structure makes fabrication difficult, and defeats the main purpose, namely compactness, of many origami-inspired engineering. In this work, we propose a novel algorithmic kirigami method that provides super...

Electron transport and recombination in three-dimensionally-ordered (3D-ordered) structure electrodes were investigated using intensity-modulated photocurrent and photovoltage spectroscopy. The surface-modified TiO2 inverse opal structure was applied as a 3D electrode. The morphology, crystalline structure and surface states of the 3D-ordered structure were characterized by SEM, TEM and XPS and...

Topsides of offshore platforms contain different equipments, therefore earthquake excitation may impose large forces on them. In designing these topsides, the interaction of the secondary systems and primary structure is not usually considered, which is not realistic. In order to study this subject a 3D model of a typical platform in the Persian Gulf is constructed and analyzed, using OpenSees ...

The goal of this research is to develop a 3D topological structure with validation functionality and a conversion function. Based on this research question, some sub questions have been defined and a research methodology. The outline of this research is elaborated in chapter 1. The first use of topology has been attributed to Euler in 1736, since then, topology has evolved in mathematics but al...

Direct coupling analysis of nucleotide coevolution provides a novel approach to identify which nucleotides in an RNA molecule are likely in direct contact, and this information obtained from sequence only can be used to predict RNA 3D structures with much improved accuracy. Here we present an efficient method that incorporates this information into current RNA 3D structure prediction methods, s...

3D data modelling is one of the key problems within research works of 3D GIS. This paper focused on the research of a topological model based on space partition for 3D GIS. Firstly the formal definition of 3D spatial features were given. Then the methods for calculating topological properties to support simplexes topologically equivalent to an n-manifold with (n-1)-pseudomanifold boundary cycle...

Chromosomal rearrangement (CR) events have been implicated in many tumor and non-tumor human diseases. CR events lead to their associated diseases by disrupting gene and protein structures. Also, they can lead to diseases through changes in chromosomal 3D structure and gene expression. In this study, we search for CR-associated diseases potentially caused by chromosomal 3D structure alteration ...

Conventional three-dimensional (3D) structure determination methods require either multiple measurements at different sample orientations or a collection of serial sections through a sample. Here we report the experimental demonstration of single-shot 3D structure determination of an object; in this case, individual gold nanocrystals at ~5.5 nm resolution using ~10 fs X-ray free-electron laser ...
