A study on the dimensional design of brackets of multi-tiered wooden pagodas in East Asia
Journal of Asian Architecture and Building EngineeringMethods for dimensional design of brackets of multi-tiered wooden pagodas in East Asia are discussed. The research method for quantifying the brackets design of each wooden five-tiered pagoda by setting a V-value with an initial value equal to 1, and ...

Canonical endomorphism field on a Lie algebra
, 2010 We show that every Lie algebra is equipped with a natural $(1,1)$-variant tensor field, the "canonical endomorphism field", naturally determined by the Lie structure, and satisfying a certain Nijenhuis bracket condition.

Advanced Functional Materials, EarlyView.Garnet‐like luminescence upon Ce3+‐activation is found in the first six representatives Li9RESi4N4O8 (RE = Y, La, Gd, Dy, Yb, Lu) of the substance class of lithium rare‐earth oxonitridolithosilicates, which also show a novel structure type. High‐temperature solid‐state synthesis yielded crystalline samples for single‐crystal X‐ray diffraction‐based ...

Advanced Materials, EarlyView.A multi‐generational compositional design creates a printable low‐loss dielectric composite that achieves over 16 W m−1 K−1. This breakthrough is enabled by thermal post‐processing, which promotes templated crystallization in a polymer matrix from surface‐modified particles, creating a “hetero‐percolated network.” The resulting material is three ...

Turkish Journal of Orthodontics, 2004 Because an important part of force is lost in friction, this friction between wire and bracket is very important for clinicians. The aim of the study is to investigate the effect of an angle on the friction resistance between the stainless steel bracket ...
