Let p : E → B be a Serre fibration with E compact, B a connected finite CW -complex, and fiber either the real Grassmann manifold O(n)/O(2) × O(n − 2) or the complex Grassmann manifold U(n)/U(2) × U(n− 2), where n ≥ 4. We prove that if n is odd, then the fiber is totally non-homologous to zero in E with respect to Z2.

In this paper we take a totally different approach via Reidemeister homotopy chains, which gives a simpler and more natural proof enabling us to visualize geometrically the free derivatives. Briefly the proof is as follows: We collapse the complement C A of the arc A in C to a 2-dimensional CW-complex K, where C is the closure of the component of S3 S2 containing A. Then it follows from [S] tha...

Abstract The period T CW and quality factor Q of the Chandler wobble (CW) as well polar motion (PM) transfer functions are all determined by Earth’s layered structure, mass distribution, elasticity, rheology energy dissipation, via dynamic figure parameters complex degree-2 Love numbers. However, most previous studies used geophysical excitations derived from real-valued PM to invert for , thus...

Given a knot presented in a grid diagram, we construct a CW complex which has one cell for each generator of the grid chain complex, and whose homology is the grid homology. This space is welldefined, and its stable homotopy type is a knot invariant. Thus to each knot, we can associate an invariant spectrum, whose F2 homology is the knot Floer homology over F2. 1991 Mathematics Subject Classifi...

Background: The dose-related effects of patient setup errors on bio-physical indices were evaluated for the conventional wedge (CW) and field-in-field (FIF) whole breast irradiation techniques (WBI). Materials and Methods: The treatment plans of 10 patients receiving left WBI were retrospectively selected for evaluation. The bio-physical effects of dose variations were evaluated by shifting the...

Aims/hypothesis We analysed the association between humoral autoreactivity to zinc transporter-8 (ZnT8) and the SLC30A8 rs13266634 polymorphism (Arg325Trp), which is located at the most distal loop in the ZnT8 protein. Methods Autoantibodies to ZnT8 were determined by RIA in 270 patients with type 1 diabetes using ZnT8 carboxy-terminal constructs (amino acids 268–369) carrying 325Trp(CW) and 32...
