Nucleic acids have been used to create diverse synthetic structural and dynamic systems. Toehold-mediated strand displacement has enabled the construction of sophisticated circuits, motors, and molecular computers. Yet it remains challenging to demonstrate complex structural reconfiguration in which a structure changes from a starting shape to another arbitrarily prescribed shape. To address th...

The automated generation of 3D models buildings from point clouds is under heavy research. Currently, this Scan-to-BIM process requires high manual effort, and the previous research in low occlusion level. We propose a novel “void-growing” approach that extracts walls, floors, ceilings automatically. Different majority current approaches starting with detecting surfaces elements, our grows void...

Given a set of rectangular items, all of them associated with a profit, and a single bigger rectangular bin, we can ask to find a non-rotational, non-overlapping packing of a selection of these items into the bin to maximize the profit. A detailed description of the (2 + )-approximation algorithm of Jansen and Zhang [8] for the twodimensional case is given. Furthermore we derive a (16 + )-appro...

A perfect parallelepiped has edges, face diagonals, and body diagonals all of integer length. We prove the existence of an infinite family of dissimilar perfect parallelepipeds with two nonparallel rectangular faces. We also show that we can obtain perfect parallelepipeds of this form with the angle of the non-rectangular face arbitrarily close to 90◦. Finally, we discuss the implications which...

The authors present the case of a nine-year-old female patient who presented with pain in her right foot associated with physical activities. After this case was diagnosed as cuboid-navicular tarsal coalition, the patient was treated surgically with resection of the coalition, thereby resolving the symptoms. The literature was reviewed and the importance of adequate physical examination and ima...

INTRODUCTION Isolated cuboid dislocations are rare injuries Jacobson (1990). It is clinically significant and important in surgical education, as it is an injury and a source of lateral foot pain that can be misdiagnosed at the time of initial presentation and may be difficult to identify clinically or with imaging Drummond and Hastings (1969). PRESENTATION OF CASE We present a case report in...

We derive an approximate energy barrier equation considering its adaptation to our model calculation employing the Néel-Arrhenius with Stoner-Wohlfarth grain or dot in magnetic recording. First, we calculate as a function of field by numerical for angle 0 180 deg between easy axis and field. This relation is represented 90 deg, taking account Pfeiffer’s approximation deg. Next, shape anisotropy...

We investigate the problem of computing a minimum volume container for the non-overlapping packing of a given set of three-dimensional convex objects. Already the simplest versions of the problem are NPhard so that we cannot expect to find exact polynomial time algorithms. We give constant ratio approximation algorithms for packing axis-parallel (rectangular) cuboids under translation into an a...
