In all, 182 and 220 replies were received from patients in group A and B, respectively. Early complications included haematoma in five (2%) and two (0.9%) patients, respectively, and wound infection in 24 (13%) and 17 (7.7%). Eight patients who had scrotal pain even before vasectomy were excluded from the analysis (two in group A and six in group B). In group A, 25 of 180 (13.8%) had a new onse...

We investigate the structure of the Minkowski sum of standard simplices in R. In particular, we investigate the one-dimensional structure, the vertices, their degrees and the edges in the Minkowski sum polytope. 2000 MSC: 52B05, 52B11, 05C07.

Let A be a finite nonempty set of integers. An asymptotic estimate of several dilates sum size was obtained by Bukh. The unique known exact bound concerns the sum |A + k ·A|, where k is a prime and |A| is large. In its full generality, this bound is due to Cilleruelo, Serra and the first author. Let k be an odd prime and assume that |A| > 8kk. A corollary to our main result states that |2 · A +...

Recently, Eisenbrand, Pach, Rothvoß, and Sopher studied the function M(m, n), which is the largest cardinality of a convexly independent subset of the Minkowski sum of some planar point sets P and Q with |P | = m and |Q| = n. They proved that M(m, n) = O(m2/3n2/3+m+n), and asked whether a superlinear lower bound exists for M(n, n). In this note, we show that their upper bound is the best possib...

The hydroxyl deformation frequencies (900-1 500 cm-l) of lasalocid A, its sodium complex, and their deuterated derivatives were studied with Raman spectroscopy. The secondary and tertiary hydroxyl groups of lasalocid A give rise to spectral lines near 1425, 1303, 1172, and 738 cm-’, typical of hydrogen-bonded hydroxyl groups. In the lasalocid A-sodium complex, these are replaced by peaks at 138...

We have produced a murine monoclonal antibody (MAb), ZX10, recognizing the NTPase/helicase domain of the hepatitis C virus (HCV) nonstructural 3 protein (NS3), from which we designed a single-chain variable fragment (ScFv). The ZX10 MAb recognized a discontinuous epitope of the NTPase/helicase domain, of which the linear sequence GEIPFYGKAIPL at residues 1371 to 1382 constitutes one part. cDNAs...
