S. Bauer and M. Furuta defined a stable cohomotopy refinement of the Seiberg-Witten invariants. In this paper, we prove a vanishing theorem of Bauer-Furuta invariants for 4-manifolds with smooth Z2-actions. As an application, we give a constraint on smooth Z2-actions on homotopy K3#K3, and construct a nonsmoothable locally linear Z2-action on K3#K3. We also construct a nonsmoothable locally lin...

The Bauer-Furuta invariants of smooth 4-manifolds are investigated from a functorial point of view. This leads to a definition of equivariant BauerFuruta invariants for compact Lie group actions. These are studied in Galois covering situations. We show that the ordinary invariants of all quotients are determined by the equivariant invariants of the covering manifold. In the case where the Bauer...

BACKGROUND In patients with spinal metastatic disease, survival prognosis is a key consideration in selection for surgery and determining the extent of treatment. Individual survival prediction however remains difficult. We sought to validate the prognostic accuracy of seven preoperative scoring systems. METHODS 61 patients surgically treated for spinal metastases were retrospectively reviewe...

objective(s):   the ongoing increasing antibiotic resistance is one of the biggest challenges faced by global public health. the perennial need for new antimicrobials against a background of increasing antibiotic resistance in pathogenic and opportunistic microorganisms obliges the scientific community to constantly develop new drugs and antimicrobial agents. lichens are known prolific sources ...

Although Bauer’s influence has been powerful, it has not been pervasive. There appear to be some in the economic development community on whom his message seems not to have made even a dent. A case in point is the much-acclaimed study by two World Bank economists, Craig Burnside and David Dollar (2000, henceforth BD). Relying on a panel data set of 56 countries over six 4-year periods (beginnin...

Modification of sample size or in a broader sense total amount of statistical information during the course of a clinical trial has drawn a great deal of attention in the past decade. In the early 90s, the modification of focus to many investigators was based on some nuisance parameter (e.g., standard deviation of a continuous response variable, background event rate of some clinical outcome), ...

A rapid (6-7 hr), modified Kirby-Bauer disk-susceptibility method, by which derivatives of tetrazolium dyes are used to enhance delineation between areas of growth and zones of inhibition, has been developed. Inoculated petri plates, prepared by the Kirby-Bauer method, were sprayed, after 6 to 7 hr of incubation (37 C), with aqueous solutions of MTT-tetrazolium or INT-tetrazolium resulting in r...
