A measurement of the KS lifetime is presented using data recorded by the NA48 experiment at the CERN-SPS during 1998 and 1999. The KS lifetime is derived from the ratio of decay time distributions in simultaneous, collinear KS and KL beams, giving a result which is approximately independent of the detector acceptance and with reduced systematic errors. The result obtained is τS = (0.89598 ± 0.0...

Genetic studies in the Lepidoptera Many of you will know that my interest in human genetics derived from breeding butterflies, and it was the phenomenon of mimicry in these insects which caused my colleague P. M. Sheppard and myself to become interested in the Rhesus blood groups, and through them in the general subject of blood group incompatibility between mother and foetus. Because the conne...

Chronic right ventricular myocardial pacing causes an asynchronous pattern of left activation, reduces ejection fraction (LVEF), and may be associated with worsening clinical outcomes in the long term. Although emergence algorithms that minimize it became possible to reduce percentage paced complexes patients sinus node dysfunction, permanent is still inevitable high-degree atrioventricular (AV...

We consider rectangular tilings of orthogonal polygons with vertices located at integer lattice points. Let G be a set of reals closed under the usual addition operation. A G-rectangle is a rectangle at least one of whose sides is in G. We show that if an orthogonal polygon without holes can be tiled with G-rectangles then one of the sides of the polygon must be in G. As a special case this sol...

We investigate how the compression size of the compressed version of a two-dimensional image changes when we cut o3 a part of it, e.g. extract a photo of one person from a photo of a group of people, when compression is considered in terms of "nite automata. Denote by c(T ) the compression size of a square image T in terms of deterministic automata, it is the smallest size of a deterministic ac...

The direct CP violation parameter Re(ε/ε) has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. With 3.3 million KL → π0π0 events collected during the 1998 and 1999 running periods, a result of Re(ε/ε) = (15.0 ± 2.7)×10−4 has been obtained. The result combined with the published 1997 sample is Re(ε/ε) = (15.3± 2.6)×10−4. 1) Present addre...

Oxidation of low-density lipoprotein (LDL), the major cholesterol-carrying protein in human blood plasma, is now commonly implicated as an initiator of atherosclerosis [1]. Oxidation of the lipid moiety appears to be a key event in the process preceding the modification of apolipoprotein B-100, eventual uptake of the lipoprotein by macrophages and the formation of foam cells [2]. A key piece of...

The paper considers broadcasting in radio networks, modeled as unit disk graphs (UDG). Network stations are modeled as points in the plane, where a station is connected to all stations at Euclidean distance at most 1 from it. A message transmitted by a station reaches all its neighbors, but a station hears a message (receives the message correctly) only if exactly one of its neighbors transmits...
