a r t i c l e i n f o A pre-and post-test quasi-experimental design was used to test the impact of a 30-week, theoretically-based social and emotional learning (SEL) curriculum, The RULER Feeling Words Curriculum (" RULER "), on the academic performance and social and emotional competence of 5th and 6th grade students (N = 273) in fifteen classrooms in three schools. Academic performance was as...

The needle length of the Yersinia spp. injectisome is determined by Yop secretion protein P (YscP), an early substrate of the injectisome itself. There is a linear correlation between the length of YscP and the length of the needle, suggesting that YscP acts as a molecular ruler. However, it is not known whether one single molecule of YscP suffices to control the length of one needle or whether...

A Golomb ruler with M marks can be defined as a set {ai} of integers so that all differences δij = aj − ai, i 6= j, are distinct. An order 2 Golomb ruler is a Golomb ruler such that all differences δijk` = |δk` − δij |, {i, j} 6 = {k, `}, are distinct as much as possible. Contruction of optimum order 2 Golomb ruler, i.e., of rulers of minimum length, is a highly combinatorial problem which has ...

BACKGROUND Cobeljić et al. recently reported a numeric table method to provide precise rotational osteotomy which is a well established orthopaedic procedure. The numeric table requires four pages in length that is rather inconvenient during performing an osteotomy operation. METHODS We thus develop our own method by summarizing the data of the four-page table into a small ruler, which is eas...

C urrent controversies over presidential power suggest. that significant separation of powers depends on the existence of some effective counterweight to the executive ruler, which in turn presupposes a disposition to restrain the ruler that does not come from the ruler himself. One might conclude that schemes for separation of powers grow out of either a fundamental opposition to ruling or at ...

Despite the known relevance of genomic structural variants to pathogen behavior, cancer, development, and evolution, certain repeat based structural variants may evade detection by existing high-throughput techniques. Here, we present ruler arrays, a technique to detect genomic structural variants including insertions and deletions (indels), duplications, and translocations. A ruler array explo...
