Ma-schlenker C -octahedra in the 2-sphere

چکیده
We present constructions inspired by the Ma-Schlenker example of [9] that show the non-rigidity of spherical inversive distance circle packings. In contrast to the use in [9] of an infinitesimally flexible Euclidean polyhedron, embeddings in de Sitter space, and Pogorelov maps, our elementary constructions use only the inversive geometry of the 2-sphere.

Composition tunable ternary Pt-Ni-Co octahedra for optimized oxygen reduction activity.
Herein, we report a one-step synthesis method for octahedral Pt-Ni-Co ternary catalysts with tunable compositions and fixed shapes. Impressively, the composition optimized octahedral PtNi0.55Co0.1/C demonstrated a significant improvement in ORR activity compared to those of previously reported Pt-Ni-Co alloy octahedra, showing an outstanding specific activity of 5.05 mA cm-2 and a mass activity...
متن کاملCounting Gluings of Octahedra
Three–dimensional colored triangulations are gluings of tetrahedra whose faces carry the colors 0, 1, 2, 3 and in which the attaching maps between tetrahedra are defined using the colors. This framework makes it possible to generalize the notion of two–dimensional 2p–angulations to three dimensions in a way which is suitable for combinatorics and enumeration. In particular, universality classes...
متن کاملThe Social Effective Factors Involved in Gender Stereotyping Believe between Private and Public Sphere
An important part of understanding women's and men's attitudes and behaviors is considering their ideas and opinions. Based on gender stereotyping of view women and men have different types of behavior, manner and characteristics. Both genders do their jobs differently. Stereotyping process focuses on ability and characteristics of women, and men are lack of them. On the other hand, it also f...
متن کاملEngineering single crystalline Mn3O4 nano-octahedra with exposed highly active {011} facets for high performance lithium ion batteries.
Well shaped single crystalline Mn3O4 nano-octahedra with exposed highly active {011} facets at different particle sizes have been synthesized and used as anode materials for lithium ion batteries. The electrochemical results show that the smallest sized Mn3O4 nano-octahedra show the best cycling performance with a high initial charge capacity of 907 mA h g(-1) and a 50th charge capacity of 500 ...
متن کاملElectrochemical Deposition and Formation Mechanism of Single-Crystalline Cu2O Octahedra on Aluminum
A simple electrochemical deposition was developed to synthesize the cuprous oxide (Cu(2)O) octahedra on aluminum foils. The average edge length of the octahedra is about 300 nm. The chemical composition of the octahedra was determined using energy dispersive X-ray spectroscopy and electron energy-loss spectroscopy. The microstructure of the octahedra was investigated using transmission electron...
