The ruthenium dye N3, cis-bis(isothiocyanato)bis(2,2'-bipyridyl-4,4'-dicarboxylato)-ruthenium(ii), deposited on Ag(111) by ultra-high vacuum electrospray ionization is investigated using low-temperature scanning tunneling microscopy. Scanning tunneling spectroscopy of single molecules reveals vibronic excitations that are related to the lowest unoccupied molecular orbital (LUMO). Switching of N...

We prove: (1) every language accepted by a two-way nondeterministic pushdown automaton can be recognized on a random access machine in O(n3/log n) time; (2) every language accepted by a loop-free two-way nondeterministic pushdown automaton can be recognized in O(n3/log 2 n) time; (3) every context-free language can be recognized onqine in O(n3/log z n) time. We improve the results of Aho, Hopcr...

Transient carbonyl nitrenes RC(O)N, formed during thermal- or photoinduced decomposition of carbonyl azides RC(O)N3, are highly liable to the Curtius rearrangement, producing isocyanates RNCO in almost quantitative yield. Contrary to common belief, we found a thermally persistent triplet carbonyl nitrene, FC(O)N, that can be produced by flash pyrolysis of FC(O)N3 in 49% yield. The computed CBS-...

The Lamé curve is an extension of ellipse, the latter being a special case. Dr. Johan Gielis further extended in polar coordinate system by introducing additional parameters (n1, n2, n3; m): rφ=1Acosm4φn2+1Bsinm4φn3−1/n1, which can be applied to model natural geometries. Here, r radius corresponding angle φ; A, B, n1, n2 and n3 are estimated; m positive real number that determines angles curve....

A general linear singular boundary value problem dxi dt = Pi(t) · x3−i + qi(t) (i = 1, 2), xi(τk+)− xi(τk−) = Gi(k) · x3−i(τk) + hi(k) (i = 1, 2; k = 1, 2, . . .); li(x1, x2) = ci (i = 1, 2) is considered, where Pi ∈ Lloc(]a, b[ ,Rni×n3−i), qi ∈ Lloc(]a, b[ ,Ri), Gi : {1, 2, . . .} → Rni×n3−i , hi : {1, 2, . . .} → Ri , ci ∈ Ri , and li is a linear bounded operator (i = 1, 2). The singularity i...

The formin homology protein, mDia1, is a major effector of Rho controlling, together with the Rho-kinase (ROCK), the formation of focal adhesions and stress fibers. Here we show that a constitutively active form of mDia1 (mDia1∆N3) affects the dynamics of microtubules at three stages of their life. We found that in cells expressing mDia1∆N3, (1) the growth rate at the microtubule plus-end decre...
