The sequences and gene organisation of two LEAP-2 molecules (LEAP-2A and LEAP-2B) from rainbow trout, Oncorhynchus mykiss are presented. Both genes consist of a 3 exon/2 intron structure, with exon sizes comparable to known mammalian genes. LEAP-2A notably differs from LEAP-2B in having larger introns and a larger 3' UTR. The predicted proteins contain a signal peptide and prodomain, followed b...

With the method of kinematics, the paper gives a new definition for “leap” and “leap-development”, and suggests that the essential property of “leap” is “acceleration”. By analysis of leap development mechanism, the paper puts forward the leap development strategy and the approach of carrying out the strategy for China conventional enterprises. Keyword: Leap development mechanism, Conventional ...

The Leap Motion controller is a consumer gesture sensor aimed to augment a user’s interactive experience with their computer. Using infrared sensors, it is able to collect data about the position and motions of a user’s hands. This data allows the Leap to be used as an authentication device. This study explores the possibility of performing both login as well as continuous authentication using ...

To study the block structure of a connected graph G = (V,E), we introduce two algebraic approaches that reflect this structure: a binary operation + called a leap operation and a ternary relation L called a leap system, both on a finite, nonempty set V . These algebraic structures are easily studied by considering their underlying graphs, which turn out to be block graphs. Conversely, we define...

A clustered randomized design was used in which 28 inclusive preschool classrooms were randomly assigned to receive 2 years of training and coaching to fidelity in the LEAP (Learning Experiences and Alternative Program for Preschoolers and Their Parents) preschool model, and 28 inclusive classes were assigned to receive intervention manuals only. In total, 177 intervention classroom children an...

We introduce Leap-List, a concurrent data-structure that is tailored to provide linearizable range queries. A lookup in Leap-List takes O(log n) and is comparable to a balanced binary search tree or to a skip-list. However, in Leap-List, each node holds up-to K immutable key-value pairs, so collecting a linearizable range is K times faster than the same operation performed non-linearizably on a...
