Cloud storage represents the trend of intensive,scale and specialization of information technology,which has changed the technical architecture and implementation method of electronic records management.Moreover,it will provide a convenient way to generate more advanced and efficient management of the electronic data records.However,in cloud storage environment,it is difficult to guarantee the trustworthiness of electronic records,which results in a series of severe challenges to electronic records management.Starting from the definition and specification of electronic records,this paper firstly analyzes the requirements of the trustworthiness in cloud storage during their long-term preservation according to the information security theory and subdivides the trustworthiness into the authenticity,integrity,usability,and reliability of electronic records in cloud storage.Moreover,this paper proposes the technology framework of preservation for trusted electronic records.Also,the technology of blockchain,proofs of retrievability,the open archival information system model and erasure code are adopted to protect these four security attributes,to guarantee the credibility of the electronic record. 展开更多

As the development of smart grid and energy internet, this leads to a significantincrease in the amount of data transmitted in real time. Due to the mismatch withcommunication networks that were not designed to carry high-speed and real time data,data losses and data quality degradation may happen constantly. For this problem,according to the strong spatial and temporal correlation of electricity data which isgenerated by human’s actions and feelings, we build a low-rank electricity data matrixwhere the row is time and the column is user. Inspired by matrix decomposition, we dividethe low-rank electricity data matrix into the multiply of two small matrices and use theknown data to approximate the low-rank electricity data matrix and recover the missedelectrical data. Based on the real electricity data, we analyze the low-rankness of theelectricity data matrix and perform the Matrix Decomposition-based method on the realdata. The experimental results verify the efficiency and efficiency of the proposed scheme. 展开更多

Bone undergoes continuous remodeling by tightly-coordinated actions of bone-resorbing osteoclasts and boneforming osteoblasts.1 Recent studies document that the dysregulation of histone methylation profiles is associated with the progression of osteoclastogenesis.However,the specific epigenetic modifiers are incompletely understood.In this study,we demonstrate an inhibitory role of a variegation 3-9 homolog 1(SUV39H1)in osteoclast formation. 展开更多
