Multilevel security or multiple levels of security (MLS) is the application of a computer system to process information with incompatible classifications (i.e., at different security levels), permit access by users with different security clearances and needs-to-know, and prevent users from obtaining access to information for which they lack authorization.
A high-level comparison of in-kernel and kernel-to-userspace APIs and ABIs The Linux kernel and GNU C Library define the Linux API. After compilation, the binaries offer an ABI. Keeping this ABI stable over a long time is important for ISVs. In computer software, an application binary interface (ABI) is an interface between two binary program ...
The likelihood-ratio test can be employed for model building in general, for examining what happens when effects in a model are allowed to vary, and when testing a dummy-coded categorical variable as a single effect. [2] However, the test can only be used when models are nested (meaning that a more complex model includes all of the effects of a ...
This yields a single-level mathematical program with complementarity constraints, i.e., MPECs. If the lower level problem is not convex, with this approach the feasible set of the bilevel optimization problem is enlarged by local optimal solutions and stationary points of the lower level, which means that the single-level problem obtained is a ...
Multi-level governance is an approach in political science and public administration theory that originated from studies on European integration.Political scientists Liesbet Hooghe and Gary Marks developed the concept of multi-level governance in the early 1990s and have continuously been contributing to the research program in a series of articles (see Bibliography).

One application of multilevel modeling (MLM) is the analysis of repeated measures data. Multilevel modeling for repeated measures data is most often discussed in the context of modeling change over time (i.e. growth curve modeling for longitudinal designs); however, it may also be used for repeated measures data in which time is not a factor.
According to ABI, the SOLiD 3plus platform yields 60 gigabases of usable DNA data per run. Due to the two base encoding system, an inherent accuracy check is built into the technology and offers 99.94% accuracy.
Acquired brain injury (ABI) is brain damage caused by events after birth, rather than as part of a genetic or congenital disorder such as fetal alcohol syndrome, perinatal illness or perinatal hypoxia. [1] ABI can result in cognitive, physical, emotional, or behavioural impairments that lead to permanent or temporary changes in functioning. [1]
