摘要:
A label anti-collision method is disclosed, which is applied in a radio frequency identification system including a reader and labels. When the labels enter into an arbitration process, the reader sends the predetermined number of labels to the labels; the reader sends start counting instruction; after a label receives the start counting instruction, the label initializes its own information, and according to the predetermined number of the labels, selects a random number as an initial value of a counter and enters into the arbitration process. A label anti-collision system is also disclosed. With the method and the system, all the labels are hashed at the beginning of arbitrating with the Binary Tree method so as to reduce the probability of the collisions and improve the arbitration efficiency.
摘要:
The present invention provides a radio frequency identification (RFID) system and a tag counting ending method for anti-collision thereof. The RFID system comprises a reader-writer and tags. The tag counting ending method comprises: in the counting process, when the reader-writer does not receive a response signal from a tag and the value of a register is not greater than a pre-determined counting ending register threshold value, the reader-writer transmits a Finish command to each of the tags and waits for responses; after receiving the Finish command, the tag determines whether the tag itself is counted successfully, if so, makes no response; if not, sets the counter of tag itself as 0 and transmits a response signal to the reader-writer; if the reader-writer receives the response signal, then determines that counting is not finished and continues to count the tag which makes response; if the reader-writer does not receive the response signal, then determines that counting is finished.

The present invention discloses a method and system for tallying tags in a radio frequency identification system. The method comprises: upon receiving a tallying command sent by the reader, the tags reflecting a first response message used for decoding and checking (S402); upon receiving the first response message, the reader sending a decoded random number (RN) if it decodes the first response message correctly; upon receiving the decoded RN, the tags reflecting a second response message containing tag ID information after confirming that the RN is consistent with their own RN (S405); and upon receiving the second response message, the reader confirming that the tallying is completed if the tag ID information contained in the second response message is correct (S407).
摘要:
A method for calendaring an activity based on roles, including the steps of acquiring a request for calendaring the activity for a plurality of roles invited to attend the activity; acquiring data on existing activities which have been calendared for all the specific individuals in the plurality of roles invited to attend the activity; and determining the time interval for holding the activity based on the data on existing activities which have been calendared for all the specific individuals in the plurality of roles invited to attend the activity and the request for calendaring the activity.
摘要:
The invention provides methods for determining the activity of a plurality of nucleic acid regulatory elements. These methods may facilitate, e.g., the systematic reverse engineering, and optimization of mammalian cis-regulatory elements at high resolution and at a large scale. The method may include integration of multiplexed DNA synthesis and sequencing technologies to generate and quantify the transcriptional regulatory activity of e.g., thousands of arbitrary DNA sequences in parallel in cell-based as says (e.g., mammalian cell based assays).
摘要:
Methods for alleviating the suppression of humoral immunity by myeloid-dependent suppressor cells (MDSCs) are provided which include the administration of a VISTA antagonist and an iNOS/NO inhibitor in a subject in need thereof, e.g., subjects with cancer or infectious disease wherein VISTA is aberrantly expressed. This combination has been discovered to elicit a synergistic or additive effect on alleviating suppression of humoral immunity by VISTA which is elicited by MDSCs.

Disclosed are Dpo4 DNA polymerase mutants with increased DNA synthesis processivity. The mutant enzymes, Dpo4 A181D and Dpo4 E63K, are constructed based on the wild-type Dpo4 derived from Sulfolobus solfataricus to obtain Dpo4DNA polymerase mutants with increased DNA processivity. The extension length of Dpo4 A181D and Dpo4 E63K are respectively increased by 25% and 18.8% than that of the wild-type Dpo4. The fidelity of Dpo4 A181D and wild-type Dpo4 are similar, and the fidelity of Dpo4 E63K is increased from that of the wild-type Dpo4. In summary, the mutants Dpo4 A181D and Dpo4 E63K obtained by the present invention have increased processivity compared to that of the wild-type Dpo4 DNA polymerase.
