Single-chain derivatives of the 434 repressor containing one wild-type and one mutant DNA-binding domain recognize the general operator ACAA-6 base pairs-NNNN, where the ACAA operator subsite is contacted by the wild-type and the NNNN tetramer by the mutant domain. The DNA-binding specificities of several single-chain mutants were studied in detail and the optimal subsites of the mutant domains...

A scandium hydride supported by a (NNNN)-type macrocycle consists of a trinuclear cation and a trinuclear anion. The anion shows significantly higher reactivity.

A novel single-chain (sc) protein framework containing covalently dimerized DNA-binding domains (DBD) of the phage 434 repressor was used to construct combinatorial mutant libraries in order to isolate mutant DBDs with altered specificities. The library members contain one wild-type DBD and one mutant domain with randomized amino acids in the DNA-contacting region. Based on previous studies, th...

In this article, we have obtained some novel results on bilateral generating functions of the polynomials, YYnn+rr αα−nnnn(xx;kk), a modified form of Konhauser biorthogonal polynomials, YYnn(xx; kk) by group-theoretic method. As special cases, we obtain the corresponding results on Laguerre polynomials, LLnn αα(xx). Some applications of our results are also discussed.

The energy spectra of light-mass kaonic nuclei were investigated using the theoretical framework $0s$-orbital model with zero-range $\bar{K} N$ and $\bar{K}\bar{K}$ interactions effective single-channel real potentials. energies NN$, NNN$, NNNN$, $\bar{K}\bar{K} N$, NN$ systems calculated in cases weak- deep-binding interaction, which was adjusted to fit $\Lambda(1405)$ mass bound state. result...

The realization that entanglement can affect macroscopic properties of bulk solid-state systems is a challenge in physics and Chemistry. Theoretical physicists often are considered the entanglement between nearest-neighbor (NN) spins and tried to find its characterizations in terms of macroscopic thermodynamics observables as magnetization and specific heat. Here, we focus on the entanglement b...

As part of the BIOSANT program (biologically-inspired smart nanotechnology), scientists at NASA-Langley have identified a “self-healing” plastic that spontaneously closes the hole left by the passage of a bullet. To understand and generalize the phenomenon in question, the mechanical properties responsible for this ability are being explored. Low-rate impression testing was chosen to characteri...
