So to define MLS policy, it is necessary to first specify a set of security levels. This set of security levels is associated with a partial order relation denoted <. If l1 and l2 are two security levels then l1 < l2 is read l1 is lower than l2. When < is a partial order relation, it may happen that both l1 < l2 and l2 < l1 and l1 = l2 are false. In this case, we say that l1 and l2 are incompar...

Programmed death-1 (PD-1), upon engagement by its ligands, programmed death ligand-1 (PD-L1) and programmed death ligand-2 (PD-L2), provides signals that attenuate adaptive immune responses. Here we describe the identification of the Pekin duck PD-L2 (duPD-L2) and its gene structure. The duPD-L2 cDNA encodes a 321 amino acid protein that has an amino acid identity of 76% and 35% with chicken an...

the present study intended to investigate the processing behavior of 2 groups of l2 learners of english (high and mid in proficiency) and a group of english native speakers on english active and passive reduced relative clauses. three sets of tasks, an offline task, and 2 online tasks were conducted. results revealed that the high-proficiency group’s performance was the same as that of the nati...

The ability to elicit cross-neutralizing antibodies makes human papillomavirus (HPV) L2 capsid protein a possible HPV vaccine. We examined and compared the humoral response of mice immunized with a HPV-16 L2 DNA vaccine or with HPV-16 L2 protein. The L2 DNA vaccine elicited a non-neutralizing antibody response unlike the L2 protein. L2 DNA vaccination suppressed the growth of L2-expressing C3 t...

teachers can influence the complex process of learning in education, in general, and in second/foreign language (l2) learning in particular. in this light, understanding the factors influencing teachers’ pedagogical success can help l2 teachers achieve more effective teaching. this study then investigated the role of spiritual intelligence (si) in l2 teachers’ pedagogical success. in so doing, ...

For high-performance chip multiprocessors (CMPs) to achieve their maximum performance potential, an efficient support for memory hierarchy is important. Since off-chip accesses require a long latency, high-performance CMPs are typically based on multiple levels of on-chip cache memories. For example, most current CMPs support two levels of on-chip caches. While the L1 cache architecture of thes...
