GEOMETRY, ALLOMETRY AND BIOMECHANICS OF FERN LEAF PETIOLES: THEIR SIGNIFICANCE FOR THE EVOLUTION OF FUNCTIONAL AND ECOLOGICAL DIVERSITY WITHIN THE PTERIDACEAE

Herbaceous plants rely on a combination of turgor, ground tissues and geometry for mechanical support of leaves and stems.Unlike Male Pump most angiosperms however, ferns employ a sub-dermal layer of fibers, known as a hypodermal sterome, for support of their leaves.The sterome is nearly ubiquitous in ferns, but nothing is known about its role in l

Erectile dysfunction (ED) is a major complication after radical prostatectomy (RP); however, debate continues regarding the efficacy of penile rehabilitation in the recovery of the postoperative erectile function (EF).This study included a total of 103 consecutive sexually active Japanese men with localized prostate cancer undergoing nerve-sparing

In order to better solve discrete 0-1 knapsack problems, a novel global-best harmony search algorithm with binary coding, called DGHS, is proposed.First, an initialization based on a greedy mechanism is employed to improve the initial solution quality in DGHS.Next, we present a novel improvisation process based on intuitive cognition of improvising
