متن کاملEarly China 23 – 24 1998 – 99
Sophia-Karin Psarras 漁聖愛 Shared Imagery: Eastern Zhou Decors and Iconographies 圖象的共通性: 東周的器物紋樣與圖象體系 Recent studies in Chinese archaeological analysis have tended to focus on the characteristics that set one region of China apart from others. While such a development allows for a more complex view of Chinese history, it obscures identification of unifying traits. In terms of material culture alo...
متن کاملColliding Message Pairs for 23 and 24-step SHA-512
Recently, Indesteege et al. [1] had described attacks against 23 and 24-step SHA-512 at SAC ’08. Their attacks are based on the differential path by Nikolić and Biryukov [2]. The reported complexities are 2 and 2 calls to the respective step reduced SHA-512 hash function. They provided colliding message pairs for 23-step SHA-512 but did not provide a colliding message pair for 24-step SHA-512. ...
متن کامل[μ-10,21-Dimethyl-3,6,14,17-tetraazatricyclo[17.3.1.18,12]tetracosa-1(23),8(24),9,11,19,21-hexaene-23,24-diolato-κ8 N 3,N 6,O 23,O 24:N 14,N 17,O 23,O 24]bis[(nitrato-κ2 O,O′)nickel(II)]
In the title centrosymmetric dinuclear nickel complex, [Ni(2)(C(22)H(30)N(4)O(2))(NO(3))(2)], each of the two Ni(II) atoms has a distorted octa-hedral geometry, defined by two N atoms and two O atoms from the macrocyclic ligand and two O atoms from a chelating nitrate anion. The two Ni atoms are bridged by two phenolate O atoms, forming a four-membered Ni(2)O(2) ring.

In the centrosymmetric and dinuclear title complex, [Mn(2)(C(22)H(22)N(4)O(2))(ClO(4))(2)], the two Mn atoms are bridged by two phenolate O atoms of the N(4)O(2) macrocycle with an Mn⋯Mn distance of 2.9228 (11) Å. The distorted square-pyramidal N(2)O(3) coordination geometry is completed by an O atom derived from a perchlorate anion.
