A Metalloprotease Disintegrin That Controls Cell Migration in Caenorhabditis elegans

Abstract: In Caenorhabditis elegans, the gonad acquires two U-shaped arms by the directed migration of its distal tip cells (DTCs) along the body wall basement membranes. Correct migration of DTCs requires the mig-17 gene, which encodes a member of the metalloprotease-disintegrin protein family. The MIG-17 protein is secreted from muscle cells of the body wall and localizes in the basement membranes of gonad. This localization is dependent on the disintegrin-like domain of MIG-17 and its catalytic activity. These results suggest that the MIG-17 metalloprotease directs migration of DTCs by remodeling the basement membrane.

Guarded evaluation: pushing power management to logic synthesis/design

Abstract: The need to reduce the power consumption of the next generation of digital systems is clearly recognized at all levels of system design. At the system level, power management is a very powerful technique and delivers large and unambiguous savings. The ideas behind power management can be extended to the logic level. This would involve determining which parts of a circuit are computing results that will be used and which are not. The parts that are not needed are then "shut off". This paper describes an approach termed guarded evaluation, which is an implementation of this idea. A theoretical framework and the algorithms that form the basis of the approach are presented. The underlying idea is to automatically determine the parts of the circuit that can be disabled on a per-clock-cycle basis. This saves the power used in all the useless transitions in those parts of the circuit. Initial experiments indicate substantial power savings and the strong potential of this approach for a large number of benchmark circuits. While this paper presents the development of these ideas at the logic level of design, the same ideas have direct application at the register-transfer level of design also.

Identification system employing verification of fingerprints

Abstract: An identification system for identifying authorized personnel compares a streaked pattern of a fingerprint of an individual with selected fingerprint patterns stored in memory of all authorized personnel in order to determine if the individual is included among the authorized personnel. The streaked pattern is compared with the fingerprint patterns stored in memory on the basis of characteristics between a reference point of a fingerprint and its relationship to other selected points of the fingerprint.

Portable communications terminal with camera capable of taking pictures

Abstract: In one side of an upper casing of a portable communications terminal, a close-range-photography camera module, suitable for close-range photography, is provided. An open lens window is provided so that a lens portion of the close-range-photography camera module is exposed. In the opposite side of the upper casing, a long-range camera module having a greater magnifying power than the close-range-photography camera module is provided. An open lens window is provided so that a lens portion of the long-range camera module is exposed. Further, there is provided a flash unit for strong illumination when necessary.
