We give the rst example of systolic freedom over torsion coefcients. The phenomenon is a bit unexpected (contrary to a conjecture of Gromov’s) and more delicate than systolic freedom over the integers. Dedicated to Rob Kirby, a lover of Mathematics and other wild places. Thank you for your inspiration. AMS Classi cation 53C22

Background T1-mapping using the Shortened Modified Look-Locker Inversion Recovery (ShMOLLI) technique [1] enables assessment of myocardial characteristics, such as oedema, scar and diffuse fibrosis. However, cardiac pathology is often accompanied by tachyarrhythmia, which may cause mistriggering and inaccurate T1 estimation. We hypothesised that systolic T1-mapping may overcome this issue witho...

Isolated systolic hypertension (systolic blood pressure of 160 mm Hg or greater, diastolic blood pressure less than 90) was investigated in the Leisure World population at Seal Beach, California. The prevalence of this condition was 13.9% if the blood pressure at the initial examination was used but dropped to 2.7% if the subsequent two determinations of blood pressure were also reviewed. Seven...

Hidden surface removal for real-time realistic display of complex scenes requires intensive computation and justiies usage of parallelism to provide the needed response time. We present a systolic algorithm that identiies visible segments on a scanline with the \real-time" characteristic: visible segments are output on-they as soon as segments are input to the systolic array. The proposed systo...

The effects of an acute increase in left ventricular systolic pressure and the effects of an intravenous isoproterenoi infusion on myocardial (segment) lengthening rate and chamber (minor axis dimension) filling rate were examined hi 12 anesthetized dogs. Measurements of left ventricular systolic pressure (by micromanometer) and of segment length and chamber dimension transients (by ultrasonic ...

Aim To study at what age group blood pressure ceases to increase for women and men Methods Applying change-point technique, we used our existing database mega base-line cross-sectional Hulu Langat Health Study that was initiated in 2000 to locate the most appropriate age limit in planning promotive, preventive and controlling strategies against systolic hypertension. Results Systolic hypertensi...

In this paper a bidirectional linear systolic array (BLSA) that computes minimum cost spanning tree (MCST) of a given graph is designed. We present a synthesis procedure, based on data dependencies and space-time transformations of index space, to design BLSA with optimal number of processing elements (PEs) for a given problem size. The execution time is minimized for that number of PEs. Explic...

A formal proof is presented for a recently presented systolic array for recursive least squares estimation by inverse updates. The derivation of this systolic array is highly non-trivial due to the presence of data contra-flow and feedback loops in the underlying signal flow graph. This would normally prohibit pipelined processing. However, it is shown that suitable delays may be introduced int...
