MicroRNAs (miRNAs) are small non-coding RNAs (ncRNAs) that mainly bind to the seed sequences located within the 3' untranslated region (3' UTR) of target genes. They perform an important biological function as regulators of gene expression. Different genes can be regulated by the same miRNA, whilst different miRNAs can be regulated by the same genes. Here, the evolutionary conservation and expression pattern of miR-10a-3p in olive flounder and rock bream was examined. Binding sites (AAAUUC) to seed region of the 3' UTR of target genes were highly conserved in various species. The expression pattern of miR-10a-3p was ubiquitous in the examined tissues, whilst its expression level was decreased in gill tissues infected by viral hemorrhagic septicemia virus (VHSV) compared to the normal control. In the case of rock bream, the spleen, kidney, and liver tissues showed dominant expression levels of miR-10a-3p. Only the liver tissues in the rock bream samples infected by the iridovirus indicated a dominant miR-10a-3p expression. The gene ontology (GO) analysis of predicted target genes for miR-10a-3p revealed that multiple genes are related to binding activity, catalytic activity, cell components as well as cellular and metabolic process. Overall the results imply that the miR-10a-3p could be used as a biomarker to detect VHSV infection in olive flounder and iridovirus infection in rock bream. In addition, the data provides fundamental information for further study of the complex interaction between miR-10a-3p and gene expression.

While clustered VOD (Video On Demand) servers that have been proposed for building large-scale VOD system recently, have the advantages of high availability and scalability, the system level reliability of the clustered VOD servers could be decreased by adding more servers to scale up the capacity of the server. To alleviate this reliability problem and support server-level fault tolerance, this paper proposes and analyzes self recovery system based on RAID-3 and 4 with pipelining concept. The proposed self recovery system could increase the efficiency of the disk by accessing the disk with large size block as in RAID-4. The network resource could be used efficiently and the workload of memory could be decreased by sending data in small size block as in RAID-3. By introducing pipeline concept, the recovery tasks are processed at several nodes in parallel so that the workload in CPU, network, and memory could be distributed to several nodes.

센서노드에서의 빠른 데이터 전달을 위한 효율적 패킷 전송 기법

Sensor network is used to obtain sensing data in vahous area. The interval to sense the events depends on the type of target application and the amounts of data generated by sensor nodes are not constant. Many applications exploit long sensing interval to enhance the life time of network but there are specific applications that requires very short interval to obtain fine-grained, high-precision sensing data. If the number of nodes in the network is increased and the interval to sense data is shortened, the amounts of generated data are greatly increased and this leads to increased amount of packets to transfer to the network. To transfer large amount of packets fast, it is necessary that the delay between successive packet transmissions should be minimized as possible. In Sensor network, since the Operating Systems are worked on the event driven, the Timer Event is used to transfer packets successively. However, since the transferring time of packet completely is varies very much, it is very hard to set appropriate interval. The longer the interval, the higher the delay and the shorter the delay, the larger the fail of transfer request. In this paper, we propose ESTEO which reduces the delay between successive packet transmissions by using SendDone Event which informs that a packet transmission has been completed.In ESTEO, the delay between successive packet transmissions is shortened very much since the transmission of next packet starts at the dme when the transmission of previous packet has completed, irrespective of the transmission timee. Therefore ESTEO could provide high packet transmission rate given large amount of packets.

Effects of task-specific rehabilitation training on tau modification in rat with photothrombotic cortical ischemic damage

Although stroke elicits progressive cognitive decline and is a leading cause of dementia, molecular interplay between stroke and Alzheimer's disease (AD) pathology has not been fully elucidated. Furthermore, studies on the effects of post-stroke rehabilitation on AD pathology are limited. We evaluated the acute effect of stroke on tau modification, and the molecular effects of task-specific training (TST) on tau modification using a model of photochemically-induced thrombosis (PIT)-induced cortical infarction. Following PIT in the dominant side of sensorimotor cortex, the rehabilitation group received 4-weeks of TST rehabilitation once daily by single pellet reaching training, whereas the sedentary control group did not received any type of training. Cortical expression levels of proteins related to tau modification were evaluated on post-stroke day 1 (PSD1) and 28; functional tests were also evaluated performed every week. The expression levels of acetyl-tau, phosphorylated-tau (p-tau), cyclooxygenase-2 and Akt-mTORC1-p70S6K pathway in infarcted cortices on PSD1 were significantly greater, whereas the expression levels of p-AMPK were significantly lower than in the paired contralateral sides. TST rehabilitation for 4 weeks greatly improved functional motor performance but not memory, which concurred with the down-regulations of ipsilateral p-AMPK, cyclooxygenase-2, Akt-mTORC1-p70S6K pathway, and p-tau in rehabilitation group. PIT-induced cortical infarction was found to induce cortical tau modification through the Akt-mTORC1-p70S6K activation, and to suppress the expression of AMPK-related proteins. TST rehabilitation greatly improved motor function, but not memory, and suppressed p-tau expression and neuroinflammation. Nevertheless, the role of TST-mediated regulation of tau hyperphosphorylation required further clarification.

Estimation of the tire slip angle under various road conditions without tire–road information for vehicle stability control

Joa, Eunhyek,Yi, Kyongsu,Hyun, Youngjin Elsevier 2019 Control Engineering Practice Vol.86 No.-

<P><B>Abstract</B></P> <P>This paper presents a tire slip angle estimator based on an Interacting Multiple Model (IMM) algorithm for vehicle stability control. The proposed algorithm is capable of estimating the tire slip angles under various road conditions without the prior knowledge of tire and road condition by only using on-board vehicle sensors. Instead of employing tire and road information, the proposed algorithm utilizes multiple numbers of model candidates to represent all aspects of vehicle motions under various road conditions. Each model candidate is a combination of lateral vehicle dynamics and transient/steady state tire dynamics. The proposed algorithm evaluates the fidelity of each model candidate to the current vehicle dynamics with probability. Moreover, in the proposed algorithm, multiple numbers of Kalman filters are embedded with these model candidates as process models. The final estimate of the proposed algorithm in each time step is a linear sum of the <I>posteriori</I> states from multiple embedded filters with the calculated probability as coefficients. The proposed estimation algorithm has been evaluated via vehicle tests. The tests have been conducted on dry asphalt and wet asphalt using a luxury passenger car equipped with a high-performance GPS for reference and data logging computer. The results have shown that the proposed estimator can successfully estimate tire slip angles with satisfactory accuracy under various road conditions</P>
