20100029003 | System and methods for identifying miRNA targets and for altering miRNA and target expression - The present invention generally relates to microRNAs such as vertebrate microRNA (miRNA), for example, mammalian miRNA. Various aspects of the invention are directed to the detection, production, or expression of miRNA. In one aspect, the invention provides systems and methods for identifying targets of miRNA sequences. For instance, in one embodiment, gene sequences comprising UTRs are compared with miRNA sequences to determine the degree of interaction, for example, by determining a free energy measurement between the miRNA sequence and the UTR, and/or by determining complementarity between at least a portion of the miRNA sequence and the UTR. In another aspect, the invention is directed to the regulation of gene expression using miRNA. For example, gene expression within a cell may be altered by exposing the cell to an oligonucleotide comprising a sequence that is substantially antisense to at least a portion of an miRNA region of the gene, for example, antisense to a 6-mer or 7-mer portion of the miRNA. In still another aspect, the invention is directed to the treatment of cancer. For instance, in one set of embodiments, an isolated oligonucleotide comprising a sequence that is substantially antisense to an miRNA, or a portion of an miRNA, is administered to a subject having or being at risk of cancer. Yet other aspects of the invention are directed to compositions or kits including oligonucleotides comprising a sequence that is substantially antisense to an miRNA (or a portion of an miRNA), methods of promoting any of the above aspects, or the like. | 02-04-2010 |

20100163308 | DIRECTIONAL DRILLING CONTROL USING PERIODIC PERTURBATION OF THE DRILL BIT - A system for steering the direction of a borehole advanced by cutting action of a rotary drill bit by periodically varying action of a drill bit while continuously rotating a drill string to which the drill bit is operationally attached. The steering system comprises a bit perturbation device cooperating with a bent housing subsection and operationally connected to the drill string and to the drill bit. Drill bit action is varied by periodic varying the rotation speed or rate of penetration of the drill bit. Periodic drill bit action results in preferential cutting of material from a predetermined arc of the borehole wall which, in turn, resulting in borehole deviation. Action of the drill bit can be varied independent of the rotation rate of the drill string | 07-01-2010 |

20130092439 | Analysis of Drillstring Dynamics Using an Angular Rate Sensor - Downhole drilling vibration analysis uses an angular rate sensor on a drilling assembly. During drilling operations, the sensor measures the angular rate of the drilling assembly. Processing circuitry is operatively coupled to the angular rate sensor and is configured to determine whether torsional type vibrations are occurring during drilling based on the angular rate data. Drilling operations can then be modified to overcome or mitigate the torsional type vibrations. | 04-18-2013 |
20150226050 | Method and Apparatus for Communicating Incremental Depth and/or Other Useful Data of a Downhole Tool - A method and apparatus for communicating incremental depth and/or other useful data of a downhole tool. The incremental depth and/or other useful data of the downhole tool being communicated by measuring at least one change in the downhole system, detecting the change downhole, and subsequently determining the incremental depth and/or other useful data of the downhole tool. | 08-13-2015 |
