Abstract:
Embodiments of the invention are directed to the utilization of trust tokens to perform secure message transactions between two devices. A trust token transmitted in a message from one device may include first data that is digitally signed by a trust provider computer, and second data that is digitally signed by the device itself. Upon receipt of a message containing a trust token, the recipient may utilize the first data to verify with the trust provider computer that the sender of the message is a trusted party. The trust provider computer may provide the recipient device the public key of the sender. The recipient may utilize the second data and the provided public key to verify that the sender signed the message and that the message is unaltered. These techniques may increase detection of relay, replay, or other man-in-the-middle attacks, decreasing the likelihood that such attacks will be successful.

A method for making a carbon nanotube film structure is related. A rotator having an axis and a rotating surface is provided. A carbon nanotube film drawn from a carbon nanotube array is adhered on the rotating surface of the rotator. The rotator is rotated about the axis to wrap the carbon nanotube film on the rotating surface of the rotator to form a carbon nanotube layer. The carbon nanotube layer is cut along a direction to form the carbon nanotube film structure.
Abstract:
The invention is directed to systems, methods, and apparatus for carrying out multi-stage amplification reactions, especially under fluidly closed conditions. In one aspect, methods of the invention are carried out in a fluidly closed reaction system that permits the isolation of a portion of a first (or prior) reaction mixture and its use as a sample or specimen in a second (or subsequent) reaction mixture, thereby substantially avoiding interfering effects that first reaction components may have in the second reaction if both reaction mixtures were simply combined together. In this aspect, systems, methods, and apparatus of the invention may be used with any amplification reaction that permits multiple stages of amplification based on the use of nested primers.

A bared part is defined at one end of the electrode lead. A pacemaker using the above mentioned electrode lead is also disclosed.
Abstract:
A method for preparing induced pluripotent stem (iPS) cells, which comprises steps as follows: step 1, introducing one or more stem cell pluripotency factors into somatic cells; step 2, culturing the somatic cells, into which the stem cell pluripotency factor has been introduced in the Step 1, by using medium supplemented with lithium salt; and step 3, identifying and characterizing the induced pluripotent stem cells. Furthermore, there provided a medium for preparing induced pluripotent stem cells, which comprising lithium salt. The medium supplemented with lithium salt is used for efficiently inducing pluripotent stem cells. Lithium salt is able to increase the production efficiency of mouse iPS cells by 5-60 times. The present method for inducing iPS cells is in favor of improving the safety of iPS technique and application of iPS cells in regenerative medicine.
