It is a familiar lesson from physical theory that interactions yield an important probe into structure. In the experiments of Rutherford almost 90 years ago, bits of matter were projected together; the physical properties of their interactions yielded evidence for a nucleus, hidden in the heart of atom. In semantics, the results of Donald Davidson in a famous 1967 paper might be viewed in a sim...

Being overweight or obese is associated with an elevated risk of tendon pathology. However, for sportspeople the epidemiological data linking weight or adiposity on one hand, and risk of tendon pathology on the other, are less consistent. Indeed, the mechanistic links between diet, adiposity and tendon pathology remain largely unexamined. Recent studies have begun to examine the effects of diet...

Muscles attach to bones via tendons that stretch and recoil, affecting muscle force generation and metabolic energy consumption. In this study, we investigated the effect of tendon compliance on the metabolic cost of running using a full-body musculoskeletal model with a detailed model of muscle energetics. We performed muscle-driven simulations of running at 2-5 m/s with tendon force-strain cu...

Previous HPSG accounts of extraction blur the distinction between valents and adjuncts by allowing verbs to lexically control the modifiers that combine with their phrasal projections. However, assuming that adjuncts are valents runs into various difficulties. This paper argues that the distinction between complements and adjuncts can be maintained, and that certain semantic phenomena that chal...

PURPOSE We aimed to provide anatomical data and mechanical tensile properties for the rectus femoris tendon to determine if it is a feasible substitute for the anterior cruciate ligament during knee joint reconstruction. METHODS The length and width of the quadriceps femoris tendon were measured from ten adult cadavers (20 knees; age =48±2 years). The anatomic features of the patellar inserti...

Compliance in jumping robots improves gait stability and enables energy-efficient locomotion. Here, 3D printable auxetic tubular springs from thermoplastic polyurethane (TPU) for rapid sustainable hopping are developed. Because the have negative Poisson's ratios, they become stiffer as compression proceeds theoretically stores 35.2% more energy than a linear spring with same stiffness. As stres...

The controllable workspace of a tendon-based Stewart Platform is the set of postures where forces and torques at the end-eeector can be controlled. A necessary and suucient condition is given for those postures where forces can be controlled; thus, a superset of the controllable workspace can be calculated easily. External forces are modeled as an additional tendon xed at iniinity by introducin...

Rupture of the extensor mechanism knee joints is rare in patients without any systemic disease. Many reports have described tendons getting ruptured at various sites mechanism. We report a case patellar tendon avulsion from tibial tuberosity on right side and quadriceps patella left sustained one accident. A 54 years old man presented with above non-identical bilateral rupture who had no pre-ex...
