In this paper we obtain a multivariable commutator lifting inequality, which extends to several variables a recent result of Foiaş, Frazho, and Kaashoek. The inequality yields a multivariable lifting theorem generalizing the noncommutative commutant lifting theorem. This is used to solve new operator-valued interpolation problems of SchurCarathéodory, Nevanlinna-Pick, and Sarason type on Fock s...

We give new formulations of the property of soundness and completeness of a resolution system and of the lifting lemma, and we discuss their relationship. The discussion points out why certain resolution systems are not complete, and that there is a simple method for showing that a resolution system is \absolutely incomplete" { that there is no notion of program completion and no logic which co...

In lifting tasks involving manual material handling the coupling component relates to the quality of the hand-toobject interface (grip). Good coupling is theorized to reduce lifting and grip stress, whereas poor coupling is theorized to increase lifting and grip stress. Choosing to lift with one hand is a decision often made by the worker. Understanding the metabolic demand of one-handed liftin...

We consider the family of facets of the binary knapsack polytope from minimal covers. We study previous results on sequential lifting in a unifying framework and explore a class of most violated fractional lifted cover inequalities, defined by Balas and Zemel, which are more general than traditional simple lifted cover inequalities. We investigate some theoretical properties of these inequaliti...

for some function φ : Ω → R. The objective is to find a lifting φ “as regular as u permits.” For example, if u is continuous one may choose φ to be continuous and if u ∈ C one may also choose φ to be C. A more delicate result asserts that if u ∈ VMO (= vanishing means oscillation), then one may choose φ to be also VMO (see R. Coifman and Y. Meyer [1] and H. Brezis and L. Nirenberg [1]). In this...

OBJECTIVES To investigate the relationship between rhegmatogenous retinal detachment (RRD) and frequent heavy lifting in a Danish working population through national register data. METHODS A dynamic cohort of all men aged 20-59 years in Denmark was followed through the Danish Occupational Hospitalisation Register from 1995 to 2010 for diagnosed RRD. Occupational categories were classified acc...

This paper addresses the development of a new rescue tool for saving survivors buried in the debris of a collapsed building caused by a large-scale natural disaster. Because access to the public energy supplies as well as the seriously stricken area are frequently cut off just after the occurrence of a large natural disaster, a new rescue tool powered by metal hydride (MH) is being proposed. Th...

Wavelet transform has demonstrated excellent compression performance with Natural images. However the performance suffers in the neighborhood of oriented edges. Under these conditions the Lifting –style implementation of wavelets are widely used in image coders. The framework of lifting offers the flexibility for developing adaptive wavelet transforms. In this paper adaptive prediction techniqu...
