The basic structures for linking squares into polyhedra and networks (reticulation) are enumerated, and corresponding examples are described in which crystals were synthesized by linking paddle wheel (square) units into metal-organic frameworks (MOFs)--named MOF-102 to MOF-112.

INTRODUCTION Racket sports require athletes to constantly improve and progress in their physical qualities in order to maintain competitive standards. This includes achieving and maintaining an optimal body composition. However, few studies have been published addressing this topic. OBJECTIVE This study tries to provide a complete anthropometric profile, including somatotype and body composit...

This study was divided into two complementary parts. In Part 1, we proposed a novel paddle strokes analysis based on the force signal from a 30-s all-out tethered test; and compared these results with video recordings. In Part 2, we investigated the relationship between force data from the same test with paddle stroke results from both methods. Eleven male elite slalom kayakers (Brazilian natio...

Few gating-modifier toxins have been reported to target low-voltage-activated (LVA) calcium channels, and the structural basis of toxin sensitivity remains incompletely understood. Studies of voltage-gated potassium (Kv) channels have identified the S3b-S4 "paddle motif," which moves at the protein-lipid interface to drive channel opening, as the target for these amphipathic neurotoxins. Voltag...

BACKGROUND Wound re-epithelialization has been traditionally described to occur from the dermal appendages of the wound edges. As such, the role of the dermal wound bed in re-epithelialization has been questioned. In a patient undergoing breast reconstruction with free tissue transfer, the buried portions of the free flap skin paddle could be either de-epithelialized or deskinned. In case of ma...

The dynamics of single-crystal silicon ;100 mm size rectangular paddle oscillators at room temperature have been studied using a recently developed high-resolution scanning laser vibrometer. The dynamic mechanical behavior is determined by scans of the entire device, providing both amplitude and phase spatial maps of the vibratory response. These reveal more than 16 normal modes below 500 kHz. ...
