The addition of Cu(I) to the random-coil peptide, C16C19-GGY, produces a self-organized, metal-bridged 4-helix bundle which displays an intense room-temperature luminescence at 600 nm. Emission, UV, and CD titrations along with X-ray absorption studies indicate that the luminescent cofactor is likely a Cu4S4 cluster in which each Cu atom is bridged by the side chains of two cysteine residues an...

Dinuclear trihydroxido-bridged osmium-arene complexes are inert and biologically inactive, but we show here that linking dihydroxido-bridged Os(II) -arene fragments by a bridging di-imine to form a metallacycle framework results in strong antiproliferative activity towards cancer cells and distinctive knotting of DNA. The shortened spacer length reduces biological activity and stability in solu...

The cartoon figure on the cover image is Monkey King, who a character in classical Chinese novel “Journey to West”. He has 72 polymorphic transformations. As shown cartoon, he only needs blow breath and can create lot of little monkeys. p-Terphenylene-bridged NiII porphyrin dimer, which similar gave syn- anti-doubly heptagon-fused dimers, spiro-pentagon-bridged chlorin doubly octagon-fused dime...

A carbazole-based triple bridging ligand (LH) consisting of two imidazole moieties at 3,6 positions with a diketone unit at the carbazole nitrogen forms carbazole-bridged zinc(II) complexes with structures of [(L(-))4(Zn(2+))n] (n = 2-6), where the strength of aromatic stacking interactions between the carbazole rings increases with an increase in the number of Zn(2+) ions bridged by the imidaz...

According to data from stent-enhanced three-dimensional optical coherence tomography, incomplete stent apposition after side branch dilation in coronary bifurcation stenting can be reduced by the free carina type (no links bridged from a carina) and by distal cell rewiring. This is the first report to describe a bent stent technique that was devised to achieve the free carina type (no links bri...

A rate-dependent model is used to represent the bridging forces acting across a 'ber-bridged slit crack in a homogeneous anisotropic elastic material, with the potential to characterize the inelastic behavior of bridged cracks in composites. The basic equilibrium equations are presented and solved, using a series of Chebychev polynomials and a suitable approximation numerical scheme. An example...

The second generation of Very-High Speed Digital Subscriber Lines (VDSL2) represents a modern high-speed solution for present last-mile access networks. However, the transmission performance of VDSL2 lines is heavily dependent on the real conditions of symmetrical pairs and quads in local metallic lines and cables. One of the frequent elements in metallic access networks, which can negatively i...

A graph is bridged if it contains no isometric cycles of length greater than three. Anstee and Farber established that bridged graphs are cop-win graphs. According to Nowakowski and Winkler and Quilliot, a graph is a cop-win graph if and only if its vertices admit a linear ordering v1 , v2 , ..., vn such that every vertex vi , i>1, is dominated by some neighbour vj , j<i, i.e., every vertex vk ...

A comparative study of the 2,3-dimethyl-3-fluoro-2-butyl cation and its chloro analog was carried out by the ab initio/GIAO-CCSD(T) (gauge invariant atomic orbital-coupled cluster with single, double, and perturbative triple excitation) method. The structures and (13)C NMR chemical shifts of the cations were calculated at the GIAO-CCSD(T)/tzp/dz//MP2/cc-pVTZ level. Bridged fluoronium ion 1, car...
