基于家庭内部议价能力与社会规范两种解释，探究夫妻间住房产权归属与家庭教育投资的关系。利用CFPS数据实证发现，通过女性劳动参与和家庭收入两种机制，女性拥有住房产权促进了家庭教育投资绝对数额增加。异质性分析显示，伴随女性受教育水平提升与受教育水平性别差距缩小，住房产权对家庭教育投资的影响得以增强，另外二者间影响仅在男孩子代与独生子女样本中表现明显。进一步分析显示，相较于女性独有产权，夫妻共享住房产权对家庭教育投资的影响更大。

Providing fault tolerance support to client-to-server applications is critical in the data center and cloud computing environments. Virtualization provides a direct way of achieving high availability by encapsulating the protected applications into the virtual machine and by periodically checkpointing the entire virtual machine(VM) state to the backup replication. However, existing VM replication solutions suffer from either excessive checkpointing overhead and network latency or unnecessary CPU resources consumption in backup replication. In this study, we exploit the ingredients of output packets and consider that the replication system maintains external consistency if the pre-released packets originate the already synchronized ***, we transform the active-active primary and slave VM combination into an active-semiactive one by shrinking the number of active virtual CPUs(v CPUs) in the slave VM. The former optimization mechanism improves the performance in read-mostly client-to-server networked applications, whereas the latter one relieves the problem of double scheduling in the slave host. Therefore, we proposed the COLO++system which is built over COLO and is a non-stop service solution with coarse-grained lock-stepping VMs for client-to-server systems. The two plus signs represent two of the optimizations. Experimental results using COLO++ implemented on KVM and Linux depict that it achieves nearly native VM performance under read-mostly workloads, as well as lower scheduling overhead in backup replication.

The realization of the parameter estimation of chirp signals using the fractional Fourier transform （FRFT） is based on the assumption that the sampling duration of practical observed signals would be equal to the time duration of chirp signals contained in the former. However, in many actual circumstances, this assumption seems unreasonable. On the basis of analyzing the practical signal form, this paper derives the estimation error of the existing parameter estimation method and then proposes a novel and universal parameter estimation algorithm. Furthermore, the proposed algorithm is developed which allows the estimation of the practical observed Gaussian windowed chirp signal. Simulation results show that the new algorithm works well.

Hand, foot and mouth disease(HFMD) is a significant health concern in the Asia–Pacific regions for infants and young children in recent years. However, no vaccines or therapeutics are available at present. The causative agents for HFMD include human enterovirus 71(EV71), coxsackievirus A16(CVA16) and some other viruses. Recently, tremendous progress has been made in the development of monovalent and bivalent vaccines against HFMD. A few neutralizing monoclonal antibodies against EV71 or CVA16 have been identified and characterized. Here, we reviewed some achievements for the development of broadly protective vaccines and neutralizing antibodies against HFMD, and discussed challenges and prospects toward broadly protective multivalent vaccines and therapeutic antibodies against HFMD.

BACKGROUND： A cerebral cavernous malformation-1 （CCM1） gene mutation might result in functional loss of KREV interaction trapped-1 （KRIT1）, which is related to onset of cavernous malformations （CM）. However, data addressing sporadic CM in Chinese patients remains limited to date. OBJECTIVE： To analyze CCM1 mutation of Chinese patients with sporadic intracranial CM. DESIGN, TIME AND SETTING： Genetics experiment was performed in the Department of Neurosurgery, Huashan Hospital Affiliated to Fudan University between January 2004 and December 2005. PARTICIPANTS： Ninety patients with sporadic CM served as the CM group, and 30 healthy subjects were considered to be the control group. METHODS： Peripheral blood was collected from patients with CM and from control group subjects Genomic DNA was extracted, and exons 8, 9, 11, 12, 13, 15, 16, 17, and 18, as well as the related introns, were amplified using polymerase chain reaction. DNA sequences were compared with GeneBank. MAIN OUTCOME MEASURES： Abnormal mutable site of CCM1 gene in the two groups. RESULTS： Four exclusive mutations of CCM1 were detected in the CM group, with a sporadic CM mutational rate of 32% （6/19）. Of the four exclusive mutations, there was one missense mutation [exon 12, 1172C→T （S391 F）], one insertion mutation [exon 8, 704insT （K246stop）], one intervening sequence mutation （IVS12-4C→T）, and one synonymous mutation （exon 17, 1875C→T）. With the exception of 1875C→T, all mutations detected in the CM group led to functional changes of the KRIT1 protein, which was encoded by the CCM1 gene. Gene mutations were not detected in the control group. CONCLUSION： Four exclusive mutations of the CCM1 gene were determined in Chinese patients with sporadic CM, which led to functional changes or loss of the encoding KRIT1 protein. KRIT1 protein is considered to be the genetic basis of CM occurrence.
