We prove an upper bound for the spectral radius of the Hadamard product of nonnegative matrices and a lower bound for the minimum eigenvalue of the Fan product of M-matrices. These improve two existing results. During the annual planni...

A modular multichannel microdrive (‘hyperdrive’) is described. The microdrive uses printed circuit board technology and flexible fused silica capillaries. Ghd Stockists Leicester The modular design allows for the fabrication of 4–...

An improved automated apparatus for measuring rotation (circling behavior) is described. The apparatus may be designed for either mice or rats. The logic circuit differentiates between complete 360° rotations and incomplete oscillatory...

Recent evidence from vector autoregressions points towards the importance of interest rate innovations in explaining output variations. We show that this evidence supports an interpretation of business cycles based on nominal contractua...

We have quantitatively studied the behaviour of a time projection chamber (TPC for the DELPHI detector) at small distances from the frame (less than 1 cm). The severe drop in gain near the frame can be overcome by shaping the electric f...

This paper examines the redundancy of tariff protection when there is a single domestic monopolist producer. The cases where the monopolist exports in free trade and where he confronts import competition are distinguished and a general ...

Airborne lead has been Babyliss Pro measured at four urban, one semi-urban and one rural site in Wales during 1984, 1985 and 1986 to assess the effect of the reduction in lead additives in petrol which was required by an EC Directive at...

The paper deals with the convergence of discrete approximations to optimization problems governed by neutral functional differential inclusions. The discrete approximations through Euler finite difference are constructed and the converg...

A signal-conditioning circuit is presented which converts the small signal of a thermal-flow sensor into a digital signal. A balanced chopper with bipolar transistors combined with a class B sigma delta converter keeps the offset beneat...

US-based National Quality Care Inc is planning to adopt a new business plan that is devoted to the research, development, manufacture and sale of a portable, wearable artificial kidney device, according to reports in the US press.This i...
