A LIM protein gene homologue of the CRP (cysteine­rich protein) family in the whiter-spotted flower chafer, Protaetia brevitarsis, was cloned. The P. brevitarsis LIM protein cDNA encodes a 92 amino acid polypep­tide with a predicted molecular mass of 10,030 Da and a pI of 8.57. The P. brevitarsis LIM protein contains the cysteine-rich consensus sequence of LIM domain and the glycine-rich consensus sequence observed in the cysteine-rich protein family 1 (CRPl). The potential nuclear targeting signal is retained. The deduced amino acid sequence of the P. brevitarsis LIM protein cDNA showed 92$\%$ identity to another beetle, Apriona germari LIM protein. Northern blot analysis showed that P. brevitarsis LIM protein is highly expressed in epidermis and midgut, but not in the fat body.

In recent year, the cores of ubiquitous environment are sensor networks and RFID systems. RFID system transmits the electronic information of the tag to the reader by using RF signal. Collision happens in RFID system when there are many matched tags, and it degrades the tag identification performance. Such a system needs algorithm which is able to arbitrate tag collision. This paper suggests a hybrid method which reduces collision between the tags, and can quickly identify the tag. The proposed method operates based on certainty, which takes an advantage of tree based algorithm, and to reduce collision it selects transmission time slot by using tag ID. The simulation results show the suggested method has higher performance in the number of queries and collision compared to other tree based and hybrid algorithms.
