摘要:
A distributed feedback semiconductor laser having a diffractive grating on an active layer in order to generate stimulated emission by recombing electrons with positive holes thereon by the light distributed feedback. This laser can achieve precisely single wavelength longitudinal mode lasing as a thin buffer layer is grown on the surface of the semiconductor layer which has been etched with irregular pattern corresponding to the diffractive grating while the corrugated pattern is being maintained intact and an active layer is grown on the surface thereof in a manner to fill in the valleys of the corrugated pattern as much as possible so that a diffractive grating is formed on the active layer and light distributed feedback is caused mainly by the periodic perturbation of gain coefficients stimulated by the diffractive grating.

The invention generally features compositions and methods for expanding long term hematopoietic stem cells (HSCs) in a population of cells. In particular, the invention relates to a method of expanding long term HSCs by culturing an initial population of HSCs with macrophages that promote self-renewal of long term HSCs. The expanded cell population provides a source of cells for therapeutic treatments utilizing HSC transplantation.

The present disclosure provides an information search method and system applicable in an information search system wherein each document has corresponding forward index data to address the issue of low search efficiency suffered by existing information search techniques. In one aspect, the method may include: receiving an inquiry word and obtaining one or more keywords contained in the inquiry word by segmentation; searching one or more documents matching the one or more keywords and forward index data corresponding to the one or more documents through the information search system's inverted index data; and determining an abstract of each of the one or more documents according to a corresponding document's forward index data, and outputting the abstract and information of the one or more documents as a search result. The proposed techniques can increase efficiency of information search and, at the meantime, guarantee accuracy of the search to a certain extent.

Methods for identifying rock properties in real-time during drilling, are provided. An example of an embodiment of such a method includes positioning one or more acoustic sensors to detect drill sounds emanating from the drill bit and the rock encountered during drilling operations, connecting the sensors to select components of a drilling rig to maximally pick up the drill sounds of the drill bit engaging rock during drilling operations. The method also includes providing and deploying an inductive telemetry, wireless telemetry, or wired transmitting system. The method also includes providing and configuring a computer to analyze the “raw” acoustic signals received from the acoustic sensors through the respective transmitting system.
