The present invention provides a method for preparing homogeneous stem cells and/or precursor cells in a large amount, in a simple and efficient manner, from human (in particular, the subject per se). The present invention further provides a method for preparing tissue implant or graft in a large amount by the use of the stem cells and/or precursor cells of the present invention. The present inventors have unexpectedly discovered that an aspirate from liposuction contains a large number of stem cells and have established a method for preparing stem cells from such an aspirate from liposuction, and thereby achieved the above-mentioned object.

Stem cell reprogramming genes cloned into a single sustained expression-type Sendai viral vector are shown to reprogram differentiated somatic cells into induced pluripotent stem (iPS) cells without integration of vector sequences into the host cell's genome. The genes are transduced into normal differentiated somatic cells via infection with recombinant Sendai virus. After expression of the reprogramming genes and subsequent induction of pluripotency, the vector genome RNA including the reprogramming genes is removed from the cell to establish an iPS cell that is genetically identical to the parent somatic differentiated cell thus reducing the risk of tumorigenic transformation caused by random integration of vector sequences into the host genome. The method promises to provide safe, autologous iPS cells that can be used for human cell replacement and regeneration therapeutic applications.

A frequency domain transforming section 2 transforms mixed signals observed by multiple sensors into mixed signals in the frequency domain, a complex vector generating section 3 generates a complex vector by using the frequency-domain mixed signals, a normalizing section 4 generates a normalized vector excluding frequency dependence of the complex vector, and a clustering section 5 clusters the normalized vectors to generate clusters. Then, a separated signal generating section 6 generates separated signals in the frequency domain by using information about the clusters and a time domain transforming section 7 transforms the separated signals in the frequency domain into separated signals in the time domain.

This invention relates to a method and processor (19) for power analysis in digital circuits. The method incorporates a main processor (19) and an associative memory mechanism (101a, 101b, 102, 104, 105, 106), the associative memory mechanism comprising a plurality of associative arrays (101a, 101b), an input value register (102), at least one result register (104) and a memory block area (29). A circuit design is transformed into a functionally equivalent model format suitable for processing in the associative array and thereafter input vectors are applied to the circuit and a record is kept of the inputs and or the outputs on each of the gates in the circuit over a specified time period. In this way, it is possible to calculate the leakage power dissipation as well as both the toggle dynamic power and the transition dynamic power.

The invention relates to a computer system, a computer-implemented method, a computer program product and a user interface for controlling, detecting, regulating, and/or analyzing biological, biochemical, chemical and/or physical processes, comprising at least two units which are designed to receive a substance or material in order to carry out at least one biological, biochemical, chemical, and/or physical process on said substance. Each unit has at least one sensor which is designed to detect measurement data relating to the process. Additionally, the computer system comprises at least one display unit via which the measurement data of the two units is displayed in respective temporal correlations which allows information to be obtained on a relationship inherent in the displayed measurement data.

An apparatus and a method for active reduction of the noise emission from a jet engine having an air inlet, a gas outlet and an engine arranged between the air inlet and the gas outlet. A first acoustic transducer is arranged in the air inlet upstream of the engine and/or in the gas outlet downstream of the engine in order to convert sound waves into first signals that are a measure of the frequency, amplitude and phase of the sound waves. An electronic control unit converts the first signals into second signals. A second acoustic transducer is centrally arranged in the air inlet upstream of the engine and/or in the gas outlet downstream of the engine in order to convert the second signals into compensation sound waves whose frequency, amplitude and phase are such that the sound waves and the compensation sound waves at least partially cancel one another out.

The quick-release chuck for a rotary power tool is provided for holding a tool bit. The chuck includes a barrel having an axial bore to receive the tool bit and an axially movable sleeve operable to position a locking member to selectively lock or release the tool bit. A proximal end of the chuck near the housing of the power tool includes a low-profile collar which holds a spring in compression against the sleeve, biasing the sleeve in a distal, locked position. The components of the chuck may advantageously be assembled in a stacked manner. The low-profile collar permits the chuck to occupy a minimal length and to be positioned with a minimal separation from the housing of the power tool for enhanced safety.

A color sequential display operative in one of two alternate modes. The first mode is a color sequential mode in which primary color images are displayed in successive frames while respective background light sources are simultaneously flashed on the display. The second mode is a monochrome mode in which the luminance Y signal is displayed in successive frames along with flashes of background white light.

A “Complete Body Fitness Machine” that provides for a muscle building workout as well as a cardiovascular workout for the total body consists generally of an adjustable seat and two arms on either side, which are adjustable in height and have an infinitely and independently variable resistance possible in either clockwise or counterclockwise rotation. The arms are designed to have several types of mechanisms attached, so as to be able to work with a variety of body parts including, but not limited to, hands, arms, legs, feet, torso, neck and shoulders. When the proper attachment is used, the resistance for each direction of rotation of the arm is set, and the exercise is conducted. Depending on the workout desired, the seat and arms could be adjusted to different positions as well as the seat can be free-moving. This, combined with the fact that the arms can rotate 360-degrees, allows the user to simulate rotational cardiovascular exercises such as cycling, rowing, rotation of the arms in a circular motion (similarly to how the legs rotate in the cycling motion), and even running. The two independent arms are infinitely and separately adjusted for resistance in either rotational direction. This means that the body's natural design of using opposing muscle groups such as the bicep and triceps to bend and straighten the arm can be not only be utilized, but also maximized for efficiency of operation and workout.
