PREMISE OF THE STUDY Gravitropic movements are unexpected mechanical processes that could disturb tree design allometries derived from the physics of nonliving bodies. We investigated whether the scaling law of gravitropic performance (power of -2 of stem diameter) derived from integrative biomechanical modeling is disturbed by ontogeny or environment, then discuss the silvicultural and dendroe...

One of the approaches to generate narrative consists in modeling narrative in terms of a deep structure, as introduced by narrative theories in the middle of the 20th century. This papers revisits this computational approach, and raises the central issue of dramatic tension: Would it be possible to build a computational model of dramatic tension, where tension could be managed according to the ...

fragments, secure ligaments or tendon to bone, and improve stability in weakened constructs.1–5 The spinous ligaments, ligamentum flavum, facet capsular ligament, and posterior longitudinal ligaments collectively form the natural posterior spinal tension band. The integrity of the posterior spinal ligamentous structures is critical, as they function to limit translation (anterior and posterior)...

In this paper we propose a non-stationary uniform tension controlled interpolating 4-point scheme which provides users with a single tension parameter that, for any value in the range of definition, generates a C1-continuous limit curve. This curve scheme unifies non-stationary interpolating 4-point rules that are capable of representing elements of the linear space spanned by trigonometric, po...

Myocardial oxygen consumption was measured in 11 anesthetized, open-chest dogs in order to compare in the same heart the relative influence on oxygen usage of tension development and the contractile or inotropic state, as reflected in V(max.) the maximum velocity of shortening of the unloaded contractile elements. The isovolumetrically contracting left ventricle was studied with left ventricula...

ANYONE CONTEMPLATING dynamic roentgenograms of hollow viscera must be impressed that the length changes in the smooth muscles that comprise their walls are larger than the threefold range produced by skeletal muscle having a fixed filament array (1), and studies of muscles isolated from these viscera confirm very long functional ranges. Urinary bladder muscle, for example, has been shown to gen...

Cellular networks multitask by exhibiting distinct, context-dependent dynamics. However, network states (parameters) that generate a particular dynamic are often sub-optimal for others, defining a source of "tension" between them. Though multitasking is pervasive, it is not clear where tension arises, what consequences it has, and how it is resolved. We developed a generic computational framewo...
