Early warning signs for saddle-escape transitions in complex networks [PDF]
, 2015 Many real world systems are at risk of undergoing critical transitions, leading to sudden qualitative and sometimes irreversible regime shifts. The development of early warning signals is recognized as a major challenge.

Journal of NeuroEngineering and Rehabilitation, 2021 Introduction After a stroke, a wide range of deficits can occur with varying onset latencies. As a result, assessing impairment and recovery are enormous challenges in neurorehabilitation. Although several clinical scales are generally accepted, they are

Effects of saddle tilt and stirrup length on the kinetics of horseback riders [PDF]
PeerJ, 2022 Background How the modification of saddle fitting parameters in horse riding affects rider’s kinetics is very uncertain. The aim of this study is to describe how manipulating the two main adjustments that an end-user is likely to perform (saddle tilt and

Saddle pulmonary thromboembolism [PDF]
QJM, 2013 A 27-year-old previously healthy man was presented to the emergency department with acute onset breathlessness since 9 h. He denied a history of fever, cough, chest pain and haemoptysis. There was no history of chest trauma. On examination, he was in respiratory distress with a respiratory rate of 40/min. His oxygen saturation was 85% by pulse oximetry

The saddle-straddle method to test for Wada basins
, 2020 First conceived as a topological construction, Wada basins abound in dynamical systems. Basins of attraction showing the Wada property possess the particular feature that any small perturbation of an initial condition lying on the boundary can lead the ...

Evolution of transonicity in an accretion disc [PDF]
, 2007 For inviscid, rotational accretion flows driven by a general pseudo-Newtonian potential on to a Schwarzschild black hole, the only possible fixed points are saddle points and centre-type points.
