Virtual knots undetected by 1 and 2-strand bracket polynomials [PDF]
arXiv, 2004 Kishino's knot is not detected by the fundamental group or the bracket polynomial; these invariants cannot differentiate between Kishino's knot and the unknot. However, we can show that Kishino's knot is not equivalent to unknot by applying either the 3-strand bracket polynomial or the surface bracket polynomial.

Advanced Synthesis &Catalysis, EarlyView.Abstract Pd‐catalyzed reactions are among the most straightforward and efficient methods to proficiently build Csp2‐Csp2 bonds. Nevertheless, thermal activation remains mandatory in most cases, which may decrease the compatibility with sensitive functional groups.

Abstract categorial grammars with island constraints and effective decidability [PDF]
arXiv, 2019 A well-known approach to treating syntactic island constraints in the setting of Lambek grammars consists in adding specific bracket modalities to the logic. We adapt this approach to abstract categorial grammars (ACG). Thus we define bracketed (implicational) linear logic, bracketed lambda-calculus, and, eventually, bracketed ACG based on bracketed ...

Advanced Theory and Simulations, EarlyView.Analytic morphing of wurtzite nanowire cross sections to arbitrary shapes yields numbers of nanowire atoms, of bonds between these and of nanowire interface bonds, plus the nanowire cross section area. The ratios of above variables help to interpret any spectroscopic nanowire data which depend on diameter and cross section shape, and can be applied to ...

Ion−π interactions for constructing organic luminescent materials
Aggregate, Volume 3, Issue 6, December 2022., 2022 The construction of organic fluorescence and room temperature phosphorescence materials by using ion−π interactions including anion−π interactions and cation−π interactions is presented in this minireview. The applications of these ion−π type organic luminescent materials in bioimaging, imaging‐guided anticancer, and antibacterial treatment are also ...
