The Poincare plot (named after Henri Poincare) is a popular two-dimensional visualization tool for dynamic systems due to its intuitive display of the dynamic properties of a system from a time series. This book presents the basis of Poincare plot and focus especially on traditional and new methods for analysing the geometry, temporal and spatial dynamics disclosed by the Poincare plot to evaluate heart rate variability (HRV). Mathematical descriptors of Poincare plot have been developed to quantify the autonomic nervous system activity (sympathetic and parasympathetic modulation of heart rate). Poincare plot analysis has also been used in various clinical diagnostic settings like diabetes, chronic heart failure, chronic renal failure and sleep apnea syndrome. The primary aims of quantification of the Poincare plots are to discriminate healthy physiological systems from pathological conditions and to classify the stage of a disease. The HRV analysis by Poincare plot has opened up ample opportunities for important clinical and research applications. Therefore, the present book can be used either for self-study, as a supplement to courses in linear and nonlinear systems, or as a modern monograph by researchers in this field of HRV analysis.

They Must Fall: Muhammad Ali and the Men He Fought features powerful and often moving images and stories of Muhammad Ali and the men he fought in the ring, by award-winning photographer Michael Brennan. "Around 1978, I had been in Houston, Texas photographing former Ali opponent George Foreman who had then reinvented himself as a roadside preacher. On the plane back to NYC, I thought, 'If that's what George is doing, I wonder what the rest of his opponents are up to?' I set out to track down as many of the old guys as I could find." Brennan spent decades locating Ali's former opponents to discover what had become of them. This unique book is a look through Brennan's remarkable archive, containing numerous never-before- seen photos plus poignant stories illuminating the images and contextualising Ali's powerful role in the world of sport. Includes a special introductory essay by the late, great Jimmy Breslin. "Michael Brennan's iconic 1977 portrait photograph of Muhammad Ali captures something far bigger and deeper than just the beautiful face of a beautiful man. It is a detailed map of the personal journey of one whose incomparable talents and audacity caused literati to swoon, taught a generation to question authority, and ultimately altered the path of a society which had never before seen a man exactly like him. To look at him the way he was then is to remember, with joy and sorrow, who we all once were." - Jim Lampley, discussing the cover image (Boxing commentator, HBO Sports)

Terence Young writes and directs this World War Two action drama. After the success of the Normandy landings, the British Guards Armoured Division sweeps across Europe, taking part in the liberation of Belgium before becoming entangled in the bloody German counter-attack in the Ardennes. Three soldiers are granted leave and return to their normal lives in England - but before long, they are recalled to duty and find themselves on the most perilous mission they have ever undertaken: a daring reconnaissance mission during the advance on Berlin.

World War Two thriller starring John Mills. While out on routine patrol, the Royal Navy submarine Trojan accidentally strikes an electronically-operated drifting mine, and plunges immediately to the sea bed. As time - and air - start to run out, the Captain, Lt Cmdr Armstrong (Mills) gathers the handful of survivors together and tries to figure out the best means of escape. Richard Attenborough and Nigel Patrick co-star.
