Identifying genes that influence phenotypic variation is extremely difficult, especially when the allelic variants only have a small effect. A recent study has used a novel approach to identify a gene that affects the behaviour of mice.

A viologen–phenylene–imidazole (VPI) conjugate, previously shown to be singly complexed by CB[7] and doubly bound CB[8], is herein form antiparallel triple stacks in water with cucurbit[10]uril (CB[10]), pairwise complexing the guest trimer. The quinary host:guest 2:3 complex showed features assignable charge-transfer interactions. Under reductive conditions, CB[10] could solubilize a VPI radic...

SOCIAL CLASSES.-The basic unit of the social class grouping is the occupational group. Every occupation in the country, of which there are many thousands, is assignable to one or other of 586 occupational unit groups (General Register Office, 1951). These 586 occupational groups are each assigned as a whole to one or other of five social classes (Table I), on the basis of the predominant charac...

A new ruthenium(ii) polypyridyl-platinum(ii) diethynyl triad containing 3-ethynylphenanthroline linked by platinum(ii) bis-tributylphosphine organometallics, Ru(ii)-Pt(ii)-Ru(ii), and platinum(ii) bis-ethynylphenanthroline complex has been prepared. The ruthenium(ii)-metal triads, Ru(ii)-M-Ru(ii) (M = Pt(ii) and Au(i)), showed typical MLCT absorption bands and a lowest energy pi-pi* absorption ...

Control charts are widely implemented in firms to establish and maintain statistical control of a process which leads to the improved quality and productivity. Design of control charts requires that the engineer selects a sample size, a sampling frequency and the control limits for the chart. In this paper, a possible combination of design parameters is considered as a decision making unit whic...

In this paper we present several algorithms which combine a partial enumeration with meta-heuristics for the solution of general mixed-integer programming problems. The enumeration is based on the primal values assignable to the integer variables of the problem. We develop some algorithms for this integration, and test them using a set of well-known benchmark problems. Key-words: Enumeration, L...

This paper studies the relation between types and normalization in the context of Combinator Systems. It presents notions of approximants for terms, intersection type assignment, and reduction on derivations; the last will be proved to be strongly normalizable. With this result, it is proved that, for every typeable term, there exists an approximant of that term with the same type, and a charac...

We study the π-calculus, enriched with pairing and non-blocking input, and define a notion of type assignment that uses the type constructor →. We encode the circuits of the calculus X into this variant of π, and show that all reduction (cut-elimination) and assignable types are preserved. Since X enjoys the Curry-Howard isomorphism for Gentzen’s calculus LK, this implies that all proofs in LK ...

A manufacturing process cannot be released to production until it has been proven to be stable. Also, we cannot begin to talk about process capability until we have demonstrated stability in our process. This means that the process variation is the result of random causes only and all assignable or special causes have been removed. In complicated manufacturing processes, such as drilling proces...

Principal component analysis-based two-dimensional (PCA2D) correlation spectroscopy, combined with the eigenvalue manipulating transformation (EMT) of a spectral data set, was applied to the temperature-dependent IR spectra of poly(hydroxybutylate) (PHB). In asynchronous PCA2D correlation spectrum, we clearly captured the existence of two components in the crystalline band of the C=O stretching...
