In both attention conditions, the example neurons had characteristic sigmoidal CRFs, but the responses were stronger while the animal was paying attention to the preferred direction (filled symbols, solid lines) relative to when the same stimuli appeared but the animal's attention was directed toward the null stimulus (open symbols, dashed lines).
Admittedly, our population-specific Ne estimates may suffer from several sources of potential bias (null alleles, open population, metapopulation setting).
Potential catalytically defective mutants in the putative endonuclease domain of Mlh3 exhibit the same meiosis and CO defect of mlh3 null mutants, opening the possibility that Mlh3 might be an endonuclease active in the Msh4 Msh5 CO pathway (Nishant et al. 2008).
Null effects are open to a number of interpretations, particularly the possibility of a Type 2 error (i.e., failing to find a true difference due to lack of power or other methodological error).
FALCON is designed to address these deficiencies, enabling the calculation of nestedness and statistical significance by using a variety of measures and null models, with open source code provided for several platforms.
Once we consider algorithms with matrix inverses such as RLS algorithms, it is well understood that with a lack of persistent excitation, a null space in the solution opens up that offers the algorithm a wide space to diverge.
Nulls, however, operate under the open world assumption, in which some items stored in the database are considered unknown, making the database's stored knowledge of the world incomplete.
Locomotor abilities and anxiety levels were preliminarily analyzed by submitting 2-month-old PC3/Tis21-null and WT mice to open field and plus maze tests [65], [66].
CSW-1 and CATP affect WCC occupancy on the frq promoter in opposite ways: CSW-1 appears to promote nucleosome compaction because the csw-1-null mutant has a relatively open chromatin structure.
These experiments were designed to investigate the performance of baffled and open divertors with single-null plasmas and particle control in double-null plasmas.
To assess the complementation of the Arabidopsis null mutant ndr1-1 [ 20], the open reading frame of CaNDR1a was cloned into the binary vector pCAMBIA 1305.1 (Cambia, Brisbane, Australia) downstream of the strong and constitutive 35S promoter of the cauliflower mosaic virus.
