We present some techniques in C.C.C. forcing, and apply them to prove consistency results concerning the isomorphism and embeddability relations on the family of X,-dense sets of real numbers. In this direction we continue the work of Baumgartner [2] who proved the axiom BA stating that every two Xi-dense subsets of R are isomorphic, is consistent. We e.g. prove Con(BA+ (2’0 > X,)). Let (KH, S)...

We try to control many cardinal characteristics by working with a notion of orthogonality between two families of forcings. We show that b < g is consistent. This work is dedicated to James Baumgartner on the occasion of his 60th birthday.

My main research interest is software engineering, with a focus on improving programmer productivity. I develop techniques and tools that make both managers and developers aware of history: learning from past successes and failures, helps us create better software. My research activities cover program analysis, aspect-oriented programming, empirical studies, and in particular, the analysis of s...

Patients with pectus carinatum are at risk for a disturbed body image and reduced quality of life. Until recently, treatment required surgical reconstruction. A growing body of literature, however, now supports the use of orthotic bracing as a nonoperative alternative in select patients. This article reviews the current literature and describes the evaluation and management of children with pec...

In the past lecture we introduced 3-player variants of both the CHSH and Magic Square games. These have the property that, even though from the point of view of classical players the new games are exactly as hard as the 2-player variants (ω(CHSH2) = ω(CHSH3) and ω(MS2) = ω(MS3)), for quantum players the 3-player variants proved much more challenging: we showed ω∗(CHSH3) = ω(CHSH3) < ω∗(CHSH2) a...

nature which gave to Thompson's work a value of its own. But not less necessary for this work, upon which Thompson and the Society were alike engaged, was his ability to consider his subject from every view-point; to state in exact proportion the evidence which told in favour of, or against, a hypothesis that had to be examined. There has passed into the hands of the Societ}' an unfinished piec...

1916), believed that whitening of hair was related to pigment absorbed and carried away by phagocytes he observed in the vicinity of dystrophic hair follicles and called 'pigmentophages' [9]. In 1981, Guin et al. [10] reported a lady whose hair turned white over 3 months with hair thinning but no patches of alopecia. Immu-nofluorescence studies demonstrated immune deposits along the follicular ...
