one of the locations of renal artery atherosclerosis is at the orifice of the renal artery, therefore thestructure of this orifice was assessed in 6 normal, adult male dogs by light microscopy (lm) andtransmission electron microscopy (tem). for the lm study, processed tissues were embedded in paraffinand sectioned serially into 6-μm thickness. sections were stained with orcein. for the tem stud...

For an edge-bicolored graph G where each edge is colored either red or blue, a vertex set S is a dual feedback vertex set if S hits all blue cycles and red cycles of G. In this paper, we show that a dual feedback vertex set of size at most k can be found in time O∗(ck1) and all minimal dual feedback vertex set of size at most k can be enumerated in time O(c +k 2 ) by compact representations for...

The elevated aerodynamic performance of insects has been attributed in part to the generation and maintenance of a stable region of vorticity known as the leading edge vortex (LEV). One explanation for the stability of the LEV is that spiraling axial flow within the vortex core drains energy into the tip vortex, forming a leading-edge spiral vortex analogous to the flow structure generated by d...

The semantic de nition of action re nement on labelled event structures is compared with the notion of syntactic substitution which can be used as another notion of action re nement in a process algebraic setting This is done by studying a process algebra equipped with the ACP sequential composition parallel composition with an explicit synchronization set and an operator for action re nement O...

BACKGROUND Cell salvage is used in obstetric surgery as part of a blood conservation strategy in our Trust. This carries a theoretical risk of amniotic fluid embolism and also a risk of fetal red cells being present in the re-infusion, resulting in alloimmunization. In this study, we attempted to quantify the risk of antibody formation from re-infusion of autologous blood after Caesarean sectio...

Dan Reznik Stan Brown John Canny fdreznik,swb,[email protected] Dept. of EECS, UC-Berkeley, Berkeley, CA 94720 USA Abstract— We use dynamic simulation to optimize the design of an existing micro-electromechanical(MEM) device, called the Manipulation Chip (M-Chip). This device contains an excess of 10,000 moving actuators, called resonators, which oscillate torsionally at a few kHz. Parts dro...

Kelly ((1975) Science, 188, 371-372) showed that a centrally-fixated, contrast-reversing edge has a very different effect on the detection of luminance and red-green flicker. Red-green flicker sensitivity was approximately 3-fold greater for a uniform field than for a 'split' field with the two sides flickering out-of-phase. Just the opposite effects were observed for luminance flicker--the spl...

Leaf area index (LAI) is an important surface biophysical parameter as an input to many process-oriented ecosystem models. Remote sensing technology provides a practical way to estimate LAI at a large spatial scale, and hence, considerable effort has been expended in developing LAI estimation models from remotely sensed imagery. LAI estimation models were usually formulated using multi-spectral...
