Panini: Reconciling Concurrency and Modularity in Design
Writing correct and efficient concurrent programs still remains a challenge. Explicit concurrency is difficult, error prone, and creates code which is hard to maintain and debug. This type of concurrency also treats modular program design and concurrency as separate goals, where modularity often suffers. To solve these problems, we are designing a new language that we call panini. In this paper...
متن کاملAqueous complexation of thorium(IV), uranium(IV), neptunium(IV), plutonium(III/IV), and cerium(III/IV) with DTPA.
Aqueous complexation of Th(IV), U(IV), Np(IV), Pu(III/IV), and Ce(III/IV) with DTPA was studied by potentiometry, absorption spectrophotometry, and cyclic voltammetry at 1 M ionic strength and 25 °C. The stability constants for the 1:1 complex of each trivalent and tetravalent metal were calculated. From the potentiometric data, we report stability constant values for Ce(III)DTPA, Ce(III)HDTPA,...
متن کاملExtraction-Separation of Eu(III)/Th(IV) Ions with a Phosphorylated Ligand in an Ionic Liquid
Extraction-separation of Eu(III) and Th(IV) ions from nitrate media into the ionic liquid 1-hexyl-3-methylimidazolium hexafluorophosphate by a phosphorylated salen extractant, bis(chlorophosphoryle)decahydro-2,4-di(2-hydroxyphenyl)benzo[d][1,3,6]oxadiazepine (DPO), is investigated. It is found that Eu(III) ions are extracted via a solvation mechanism, and the extraction of Th(IV) i...
متن کاملOn Panini and the Generative Capacity of Contextualized Replacement Systems
This paper re-examines the widely held belief that the formalism underlying the rule system propounded by the ancient Indian grammarian, Pān. ini (ca. 450–350 BCE), either anticipates or converges upon the same expressive power found in finite state control systems or the context-free languages that are used in programming language theory and computational linguistics. While there is indeed a s...
متن کاملZirconium(IV) dilanthanum(III) pentasulfide
Zirconium(IV) dilanthanum(III) penta-sulfide, ZrLa(2)S(5), crystallizes with four formula units in the space group Pnma in the U(3)S(5) structure type. The asymmetric unit comprises one Zr, one La and four S atoms. The Zr and three S atoms are situated on mirror planes. The structure consists of LaS(8) face-sharing bicapped distorted trigonal prisms and ZrS(7) edge-sharing monocapped octa-hedra.
