The longitudinal study sought to examine the dynamic development of cognitive skills for reading among elementary-level students in china's Mainland. Two groups of students in first （n=164, mean age=6.65 years at first test） and second grade （n=202, mean age=7.73 years at first test） were followed on orthographic awareness, morphological awareness and rapid automatized naming （RAN） for two years. The children exhibited significant improvement in orthographic awareness, morphological awareness and RAN from grades 1 to 4. More importantly, to the orthographic and morphological awareness, while the children took a leap from grade 1 to 2 and grade 3 to 4, the progress developed at relatively slow rates from grade 2 to 3. In order to assure children＇s development of orthographic and morphological awareness, evidence-based orthographically and morphologically enhanced instruction is needed for Chinese children in the early elementary years, especially for those at the stage from grade 2 to 3.

Radar radio frequency （RF） stealth is very important in electronic war （EW）, and waveform design and selection. Existing evaluation rules of radar RF stealth include too many parameters of radar and interceptors, such as Schleher interception factor, which makes it difficult to evaluate radar RF stealth technologies if interceptor parameters are unknown. In communication, security capacity has been presented to describe the possible ability to communicate in complete security. Since the essential of the secu- rity capacity is to have the interceptor get none valued information from the emitter, this paper is proposed to study security infor- mation factors taking advantage of mutual information to evaluate radar RF stealth under some conditions. Through analyzing mutual information obtained by the radar and the interceptor, this paper defines the security information factor with and without cooperative jamming. Furthermore, this paper deduces the ratio of the match filter to the match incoherent filter and discuss mutual information received by the interceptor. Numerical simulations illustrate radar RF stealth effects based on the security information factor concept under different conditions.

In this paper, we present a quantum-key-distribution(QKD)-based quantum private query(QPQ) protocol utilizing single-photon signal of multiple optical pulses. It maintains the advantages of the QKD-based QPQ, i.e., easy to implement and loss tolerant. In addition, different from the situations in the previous QKD-based QPQ protocols, in our protocol, the number of the items an honest user will obtain is always one and the failure probability is always zero. This characteristic not only improves the stability(in the sense that, ignoring the noise and the attack, the protocol would always succeed), but also benefits the privacy of the database(since the database will no more reveal additional secrets to the honest users). Furthermore, for the user's privacy, the proposed protocol is cheat sensitive, and for security of the database, we obtain an upper bound for the leaked information of the database in theory.

Proteasome activity reduction is an important pathological phenomenon, resulting in proteins aggregation and neuronal death in the injured neurons induced by transient ischemia. Our previous report showed that the trap of proteasome in the protein aggregates was a reason to lead to the reduction of proteasome activity. However, the patterns of proteasome entered into protein aggregates are not clear. In this study, we used a global ischemia model, Hematoxylin-Eosin staining, differential centrifuge, proteasome activity assay, sucrose gradient density centrifuge, and Western blot analysis to investigate this problem. Our results show that there are two aggregation patterns of proteasome after transient ischemia and reperfusion. One is that 26S proteasome is trapped by protein aggregates as a whole unit, and the other is that 19S or 20S is trapped in the protein aggregates, respectively, after 26S disassociates.
