Abstract: Methods and compositions for the characterizing of cancers by assessing RNA levels, such as determining an RNA pattern, are provided herein. The diagnosis, prognosis, monitoring and treatment or a cancer can be determined by detecting one or more RNAs, such as microRNAs.

Abstract: In accordance with the present invention, a pulsed induction logging system is provided which includes a logging sonde for traversing a borehole and having downhole microprocessor/controller circuitry in operative contact with a separate host computer/controller at the earth's surface. The host computer/controller and two downhole microprocessor/controllers constitute a network of digital computers and generate a digital pulsed logging code for periodically permitting a radiation coil to be driven by an oscillating current having high peak power. A powerful primary pulse of electromagnetic (EM) energy is periodically generated for irradiating the adjacent formation for induction logging purposes. The sonde also includes an antenna array for detecting secondary induced fields in the formation around the borehole. The array preferably includes a series of grouped, paired coils axially spaced along the borehole. Each group of paired coils independently detects the secondary field.

Abstract: An apparatus for making a foam pad for carpets has features to improve the quality of the pad. The apparatus has a hopper section for receiving foam particles coated with heat activated bonding agent. An extruder section compresses the particles as they are moved continuously along a conveyor belt. A heat section heats the particles after being compressed. A raking device in the hopper section rakes the top of the body of particles prior to entering the extruder section. The raking device rakes in a direction opposite to the movement of the body of particles. The raking device can be raised and lowered to change the level of the particles, and thus the density. The raking device also forms the top of the body of particles with upwardly tapered corners. A plate located below the hopper and extruder sections supports the lower conveyor belt. The heat section uses steam chambers with a perforated top, which also serves to support the conveyor belt.
