Circularly polarized light (CPL) exerts a force of different magnitude on left- and right-handed enantiomers, an effect that could be exploited for chiral resolution of chemical compounds as well as controlled assembly of chiral nanostructures. However, enantioselective optical forces are challenging to control and quantify because their magnitude is extremely small (sub-piconewton) and varies ...

Scanning small and wide angle X-ray scattering (scanning SWAXS) experiments were performed on healthy and pathologic human bone sections. Via crystallographic tools the data were transformed into quantitative images and as such compared with circularly polarized light (CPL) microscopy images. SWAXS and CPL images allowed extracting information of the mineral nanocrystalline phase embedded, with...

Helically chiral N,N,O,O-boron chelated dipyrromethenes showed solution-phase circularly polarized luminescence (CPL) in the red region of the visible spectrum (λem (max) from 621 to 663 nm). The parent dipyrromethene is desymmetrised through O chelation of boron by the 3,5-ortho-phenolic substituents, inducing a helical chirality in the fluorophore. The combination of high luminescence dissymm...

The dynamic transfer of a conjugated polymer's organization-dependent properties from the solution state to the solid film state was probed by circularly polarized luminescence (CPL) and circular dichroism (CD) spectroscopy. Different supramolecular organizations within films and aggregate solutions of a chiral poly(p-phenylenevinylene) derivative led to opposite CPL and CD spectra. These drama...

Functional materials with circularly polarized luminescence (CPL) have attracted tremendous attention due to their promising applications in three-dimensional displays, chiral recognition and catalysis, photoelectronic devices, contrast imaging, information encryption, other fields. Among various CPL-active materials, polymeric systems aggregation-induced emission (AIE) emerged as excellent can...

In this paper sequent calculi for the classical fragment (that is, the conjunction-disjunction-implication-negation fragment) of the nonsense logics B3, introduced by Bochvar, and H3, introduced by Halldén, are presented. These calculi are obtained by restricting in an appropriate way the application of the rules of a sequent calculus for classical propositional logic CPL. The nice symmetry bet...

Smart sustainable cities (SSC) tend to utilise technology promote themselves by involving their citizens in urban development. Several around the world have adopted “smart city” label recognition of these advantages. In fact, citizen engagement public development and decision making has been acknowledged globally many countries; yet, evaluations outcomes that allow contribution empowerment be m...

This document defines the Call Processing Language (CPL), a language to describe and control Internet telephony services. It is designed to be implementable on either network servers or user agents. It is meant to be simple, extensible, easily edited by graphical clients, and independent of operating system or signalling protocol. It is suitable for running on a server where users may not be al...

This note is on cautious cut elimination for one of Veltman's might logics. Syntactically, the logic is presented as an extension of a sequent system for classical propositional logic (hence: cpl). I show that this extension preserves the completeness and decidability of cpl. The proof has cautious cut elimination as a corollary. I also give a rather general syntactic proof of cautious cut elim...
