This training study investigates how children learn to refer to things unambiguously. Two hundred twenty-four children aged 2.6, 3.6, and 4.6 years were pre- and posttested for their ability to request stickers from a dense array. Between test sessions, children were assigned to a training condition in which they (a) asked for stickers from an adult, (b) responded to an adult's requests for sti...

Children come across mathematics before they start schooling. From infancy to secondary, develop mathematical concept formation skills and hold misconceptions. Learning concepts is spiral in nature, with one level affecting later learning. Poor performance traceable back Mathematics Misconceptions held by students at an early age. Animations has been used Symmetry Matrices a remarkable reductio...

Let L be the noncrossing partition lattice associated to a finite Coxeter group W. In this paper we construct explicit bases for top homology groups of intervals and rank-selected subposets L. We define multiplicative structure on Whitney in terms basis, resulting algebra has similarities Orlik-Solomon algebra. As an application, obtain four chain complexes which compute integral Milnor fibre r...

A molecular Solomon link was synthesized through the assembly of an interwoven molecular grid consisting of four bis(benzimidazolepyridyl)benzthiazolo[5,4-d]thiazole ligands and four zinc(II), iron(II), or cobalt(II) cations, followed by ring-closing olefin metathesis. NMR spectroscopy, mass spectrometry, and X-ray crystallography confirmed the doubly interlocked topology, and subsequent demeta...

Reviewing the evidence for peer-delivered services, writing in 2004 in this journal, researcher Phyllis Solomon commented on the “high level of evidence” for peer-provided services, including four randomized studies and three quasi-experimental design studies using a variety of meaningful outcome measures (Solomon, 2004). The past two decades have witnessed a number of important studies of thes...

The purpose of this paper is to study and analyze the performance and efficiency of Reed Solomon (RS) coding. In coding theory, Reed Solomon codes are the subset of BCH codes that are one of the most powerful known classes of linear cyclic block codes. Reed Solomon (RS) codes are very efficient and best for correction of burst errors and have a wide range of applications in digital communicatio...

We relate the cohomology of the Orlik-Solomon algebra of a discriminantal arrangement to the local system cohomology of the complement. The Orlik-Solomon algebra of such an arrangement (viewed as a complex) is shown to be a linear approximation of a complex arising from the fundamental group of the complement, the cohomology of which is isomorphic to that of the complement with coefficients in ...
