An innovative type called "butterfly-shaped links steel plate shear wall (BLSPSW)" was proposed as a lateral load resisting system. In this novel system, by creating butterfly-shaped links in the four sides of the web plate, the lateral load resisting mechanism is not the development of a diagonal tension field on the web plate (similar to Conventional SPSWs), but the capacity of the system is ...

Hierarchical clustering is a common method used to determine clusters of similar data points in multidimensional spaces. O(n*) algorithms are known for this problem [3,4,11,19]. This paper reviews important results for sequential algorithms and describes previous work on parallel algorithms for hierarchical clustering. Parallel algorithms to perform hierarchical clustering using several distanc...

A scheme for generating a fractal butterfly Floquet spectrum, first proposed by Wang and Gong [Phys. Rev. A 77, 031405(R) (2008)], is extended to driven SU(2) systems such as a driven two-mode Bose-Einstein condensate. A class of driven systems without a link with the Harper-model context is shown to have an intriguing butterfly Floquet spectrum. The found butterfly spectrum shows remarkable de...

There has been widespread concern that neonicotinoid pesticides may be adversely impacting wild and managed bees for some years, but recently attention has shifted to examining broader effects they may be having on biodiversity. For example in the Netherlands, declines in insectivorous birds are positively associated with levels of neonicotinoid pollution in surface water. In England, the total...

This paper studied the topology of NoC (Network-on-Chip). By combining the characteristics of the Clos network and butterfly network, a new topology named BFC (Butterfly Clos-network) network was proposed. This topology integrates several modules, which belongs to the same layer but different dimensions, into a new module. In the BFC network, a bidirectional link is used to complete information...

The title mol-ecule, C(26)H(35)NO(2), contains two cyclo-butane rings that adopt butterfly conformations and are linked by a -CH(OH)CH(2)NHCH(2)CH(OH)- bridge. In the crystal, N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds together with C-H⋯π inter-actions link the molecules.

conclusions surgical and post-surgical findings showed that this segment was not related to the patient’s femur. the foreign segment may have belonged to the other victim of this trauma. introduction femoral shaft fracture is one of the typical bone fractures due to high energy trauma and may occur as an open fracture. some foreign materials may enter the fracture site such as sand, cloth parti...
