This paper delineates experimental and numerical results concerning the effect of the stratification and the tilt on the 3D instabilities of a cylinder wake led at moderate Reynolds numbers from the 2D von Karman vortex street. For a vertical cylinder, shadowgraph visualisations put forward an unstable mode similar to the mode A well known in homogeneous fluids. When the cylinder is tilted a ne...

By means of a dynamic panel data analysis, and using a database from municipalities of the province of Barcelona (1993-99), we describe their process of fiscal adjustment to a shock in tax capacity. About 25% of the shock is internalized through an increase in tax effort, 35% through a reduction in public expenditure (mainly investment), while the rest (40%) is covered by an increase in the lev...

c-reactive protein (crp) response was studied in 44 patients with acute angina pectoris admitted to the coronary care unit. 71 % of patients with acute myocardial infarction (mi)had positive crp test while 73% of patients presumed to have unstable angina pectoris had negative crp test. this test can be helpful in differentiating between acute mi and unstable angina pectoris.

It is demonstrated that the breather solutions recently discovered in the weakly coupled topological discrete sine-Gordon system are spectrally unstable. This is in contrast with more conventional spatially discrete systems, whose breathers are always spectrally stable at sufficiently weak coupling.

In this paper, we study VC-minimal theories and explore related concepts. We first define the notion of convex orderablity and show that this lies strictly between VCminimality and dp-minimality. To do this we prove a general result about set systems with independence dimension ≤ 1. Next, we define the notion of weak VC-minimality, show it lies strictly between VC-minimality and dependence, and...
