This paper contributes to a better knowledge of the behaviour of conventional CMOS and CPL full-adder circuits when low voltage, low power or small power-delay products are of concern. It completes and overcomes limitations of previous studies as optimal power-delay curves, for CPL and CMOS full adders, have been built up using an automatic sizing tool based on statistical optimization.

Poly(quinoxaline-2,3-diyl)s containing (S)-2-methylbutoxy side chains were found to exhibit blue circularly polarized luminescence (CPL). The handedness of the CPL could be switched by a solvent-dependent helix inversion of the polymer backbone between chloroform (M-helical structure) and 1,1,1-trichloroethane (P-helical structure).

Query languages and their optimizations have been a very important issue in the database community. Languages for updating databases, however, have not been studied to the same extent, although they are clearly important since databases must change over time. The structure and expressiveness of updates is largely dependent on the data model. In relational databases, for example, the update lang...

Chrisopher Strachey was the most significant contributor to the design and implementation of the programming language CPL. At the time there was little understanding of the complexities of computer language design and how type systems could cope with lists and the kinds of structures needed to represent, for instance, parse trees. The CPL project cannot be regarded as being successful since it ...

The Call Processing Language (CPL in short, RFC2824) is an XML-based language, which provides a flexible mean to create end-user services in the Internet Telephony (VoIP). However, the service description by non-experts does not always guarantee reliable services, thus, could be a cause of system faults. This paper first proposes six classes of the semantic warnings within the CPL scripts. For ...

The paper provides an informal account of CPL, a new programming language currently being implemented for the Titan at Cambridge and the Atlas at London University. CPL is based on, and contains the concepts of, ALGOL 60. In addition there are extended data descriptions, command and expression structures, provision for manipulating non-numerical objects, and comprehensive input-output facilitie...

We review the recent progress in the field of helically assembled π-conjugated polymers, focusing on aromatic conjugated polymers with interchain helical π-stacking that exhibit circularly polarized luminescence (CPL). In Part 1, we discuss optically active polymers with white-colored CPL and the amplification of the circular polarization through liquid crystallinity. In Part 2, we focus on the...

We present a novel formulation of the modal logic CPL, a constructive logic of provability that is closely connected to the Gödel-Löb logic of provability. Our logical formulation allows modal operators to talk about both provability and non-provability of propositions at reachable worlds. We are interested in the applications of CPL to logic programming; however, this report focuses on the pre...

The combined use of chemometrics and chemiluminescence (CL) measurements, with the aid of the stopped-flow mixing technique, developed a simple time-resolved CL method for the simultaneous determination of captopril (CPL) and hydrochlorothiazide (HCT). The stopped-flow technique in a continuous-flow system was employed in this work in order to emphasize the kinetic differences between the two a...

In general, circularly polarized luminescence (CPL) is generated by a chiral luminophore, that is, structures and packing styles are essential for organic organometallic luminophores to exhibit CPL properties. However, it difficult introduce structure into inorganic metal-cluster luminophores. this minireview, we have reported magnetic (MCPL) systems. Upon the application of an external field, ...
