    Abstract: A method of characterizing shear wave anisotropy in a formation includes obtaining crossed-dipole waveforms from a borehole penetrating the formation over a range of depths and frequencies, determining far-field slowness in a fast-shear and slow-shear direction using a low-frequency portion of the crossed-dipole waveforms, and determining near-wellbore slowness in the fast-shear and slow-shear directions using a high-frequency portion of the crossed-dipole waveforms. The method also includes marking a selected depth of the formation as having intrinsic anisotropy if at the selected depth the far-field slowness in the fast-shear direction is less than the far-field slowness in the slow-shear direction and the near-wellbore slowness in the fast-shear direction is less than the near-wellbore slowness in the slow-shear direction. The selected depth is marked as having stress-induced anisotropy if the far-field slowness in the fast-shear direction is less than the far-field slowness in the slow-shear direction and the near-wellbore slowness in the fast-shear direction is greater than the near-wellbore slowness in the slow-shear direction.

    Abstract: A dynamic random access memory (DRAM) device having a vertical transistor and an internally-connected strap (ICS) to connect the transistor to the capacitor. The ICS makes no direct contact with the substrate. The DRAM cell operates at a substantially lower cell capacitance than that required for a conventional buried strap trench (BEST) cell without causing any negative impact on device performance. The lower cell capacitance also extends the feasibility of deep trench capacitor manufacturing technology without requiring new materials or processing methods. A method of manufacturing the DRAM includes forming a very thin Si layer on top of a DT cell while at the same time the method forms an isolated layer replacing a conventional collar. The formation of the SOI by internal thermal oxidation (ITO) makes the structure in such a manner that the device may be fully depleted.

    Abstract: A shock-absorbing running shoe has a sole attached to an upper, with a carriage in the upper adapted to receive the rear portion of a runner's foot. The sole has a collapsible area below the carriage. A first strut is attached to the medial side of the sole and extends above the carriage, and a second strut is attached to the lateral side of the sole and extends above the carriage. Elastic bands are coupled to the struts and to the carriage so that the carriage is suspended by the bands over the collapsible area of the sole.

    Abstract: A conduit repair system and method are disclosed for repairing ruptures in underground conduits. One embodiment of the system comprises a repair liner including fusible link twine segments and hook and loop fasteners to allow the tautly wrapping of the repair liner around the inflatable bladder of a carrier and to secure the repair liner in place by attaching fusible link twine segments to the leading and trailing edges of a carrier. Another embodiment of the system includes a hook and loop fastener to directly engage the repair liner to the bladder, in combination with a water base releasing agent coated on the bladder, with or without the use of the fusible link twine segments. The methods disclosed as contemplated by the present invention utilizes the above-described conduit repair systems in combination with an inflatable bladder carrier, a water base releasing agent coated on the bladder or a releasing material such as a plastic sleeve or sheeting attached to the carrier and wrapped between the repair liner and bladder or a combination of a water base releasing agent and a releasing material, a thermosetting resin impregnating the repair liner, and the process of the resin impregnated repair liner cocuring and bonding to the conduit inner wall surface. The fusible link segments melt during the exothermic reaction, thereby disconnecting the repair liner from the carrier.
