In the Wireless Sensor Network, a new MAC protocol: one-persistent CSMA protocol with monitoring functions and multichannel mechanism for Wireless Sensor Network based on conflict resolution algorithm is proposed. Protocol from the system throughput, collision rate, better service quality for higher priority and other aspects improve the traditional CSMA system to perfect the controllability of the system, making the system more stable for the big data, better adapted to different business. The average cycle method is used to derive rigorous mathematical expressions of specific relevant parameters. Using MATLAB simulation tool for the accuracy of the agreement is demonstrated.

ERF transcription factor involves in many aspectsof plant development and response to both biotic and abioticenvironmental stimuli. In this study, we provided evidencethat PsnERF75 can improve the salt tolerance ability oftransgenic Arabidopsis. RT-qPCR analysis described thespatio-temporal expression patterns of PsnERF75 in differentpoplar tissues. Under salt stress condition, root and leaftissues were more sensitive than stem tissue. In addition,seed germination rates of PsnERF75 transgenic Arabidopsiswere significantly enhanced. Growth status of PsnERF75transgenic Arabidopsis seedlings was much better than thatof the controls. Physiological and histochemical assaysindicated PsnERF75 transgenic Arabidopsis have a greatercapacity to eliminate reactive oxygen species and lighten thedamages to plants than the controls. Using RNA-seq analysis,100 DEGs that were significant differentially expressedbetween PsnERF75 transgenic Arabidopsis and the controlsunder salt stress conditions were identified. Seventeen upregulatedand 10 down-regulated DEGs participate in plantsalt stress response process. In addition, subcellular localizationshowed that PsnERF75 is a nuclear-localized protein. All ofthe results will provide novel insights into the functions ofERF75 in plants under abiotic stress condition.

<P>While nonfullerene small-molecule solar cells (NF-SMSCs) have relatively inferior performance compared with nonfullerene polymer solar cells, their performance is improving. In this work, a weak crystalline molecular donor BSFTR, was designed and synthesized to achieve efficient NF-SMSCs. By blending with a strong crystalline acceptor NBDTP-Fout, BSFTR achieves a well-intermixed blending morphology, which favors the formation of efficient charge percolation pathways with suppressed recombination. The BSFTR:NBDTP-Fout device obtains a power-conversion efficiency (PCE) of approximately 11.97% by achieving an efficient cathode interfacial layer (CIL)-free device that delivers an even higher PCE of 12.3%, which ranks among the top values for the reported NF-SMSCs. This work provides a simple solution for achieving high-performance NF-SMSCs by identifying the key factors for designing efficient, cost-saving, mass production-favorable CIL-free organic photovoltaic devices.</P>

This paper presents a new sensor network MAC protocol: the multi-channel p - persistent CSMA protocol with monitoring function (ACKPPCMA) from the perspective of improving the channel utilization and meeting the demand of the high QoS for high priority. Analyze the model by using the average cycle method. The Computer simulation results verify the correctness of the theory. Has some practical significance.
