Let X be a finite, n-dimensional, r-connected CW complex. We prove the following theorem: If p ≥ n/r is an odd prime, then the loop space homology Bockstein spectral sequence modulo p is a spectral sequence of universal enveloping algebras over differential graded Lie algebras.

BACKGROUND Device selection has historically been supported by minimal comparative data. Since 1994, we have implanted 43 patients with the CardioWest Total Artificial Heart (CW), 23 with the Novacor Left Ventricular Assist System (N), and 26 with the Thoratec Ventricular Assist System (T). This experience provides a basis for our device selection criteria. METHODS We reviewed retrospectively...

A RFQ linac (3MeV, 350MHz, 20mA, CW and 324cm in length) is being built for the Korea Multipurpose Accelerator Complex (KOMAC). The physical and engineering design of the H/H RFQ linac are described. The fabrication process for the cold model and structure support is described. The current status of the RFQ is reported.

Collaborative writing (CW) in policy agenda setting and grant development is an important aspect of community development. However, solutions need to be found to better deal with distributed CW. This paper establishes a basis for improving distributed, CW for policy agenda setting, and similar efforts, by using a Internet-based collaborative tool. This work utilizes key research to better under...

We show for a finite abelian group G and any element in the image of the Swan homomorphism sw : Z/|G|∗ −→ K̃0(ZG) that it can be realized as the finiteness obstruction of a finitely dominated connected CW -complex X with fundamental group π1(X) = G such that π1(X) is equal to the subgroup G1(X) defined by Gottlieb. This is motivated by the observation that any H-space X satisfies π1(X) = G1(X) a...

Let G be a rank two finite group, and let H denote the family of all rank one p-subgroups of G, for which rankp(G) = 2. We show that a rank two finite group G which satisfies certain group-theoretic conditions admits a finite G-CW-complex X ' S with isotropy in H, whose fixed sets are homotopy spheres.

Let X be a finite, n-dimensional, r-connected CW complex. We prove the following theorem: If p ≥ n/r is an odd prime, then the loop space homology Bockstein spectral sequence modulo p is a spectral sequence of universal enveloping algebras over differential graded Lie algebras.

We classify all essential extensions of the form 0 → B → D → C(X) → 0 where B is a nonunital simple separable finite real rank zero Z-stable C*algebra with continuous scale, and where X is a finite CW complex. In fact, we prove that there is a group isomorphism Ext(C(X),B) → KK(C(X),M(B)/B).

Community is a mesoscopic feature of the multi-scale phenomenon complex networks, which bridge to revealing formation and evolution networks. Due high computational efficiency, label propagation becomes topic considerable interest within community detection, but its randomness yet produces serious fluctuations. Facing inherent flaws propagation, this paper proposes series solutions. Firstly, pr...
