Mice are commonly used to examine the mechanisms by which exercise improves cardiometabolic health; however, exercise compliance and adaptations are often strain-dependent or are variable due to inconsistency in exercise training protocols. In this study, we examined nocturnal/diurnal behavior, treadmill exercise compliance, and systemic as well as cardiac-specific exercise adaptations in two c...

Previous research has demonstrated that English /r/ is perceptually more dissimilar from Japanese /r/ than English /l/ is for native Japanese (NJ) speakers. It has been proposed by the Speech Learning Model that the more distant an L2 sound (phonetic segment) is from the closest L1 speech sound, the more learnable the L2 sound will be (in: W. Strange (Ed.), Speech Perception and Linguistic Expe...

The effect of age of acquisition on first- and second-language vowel production was investigated. Eight English vowels were produced by Native Japanese (NJ) adults and children as well as by age-matched Native English (NE) adults and children. Productions were recorded shortly after the NJ participants' arrival in the USA and then one year later. In agreement with previous investigations [Aoyam...

Current efforts to reconstruct the tree of life and histories of multigene families demand the inference of phylogenies consisting of thousands of gene sequences. However, for such large data sets even a moderate exploration of the tree space needed to identify the optimal tree is virtually impossible. For these cases the neighbor-joining (NJ) method is frequently used because of its demonstrat...

Balanced minimum evolution (BME) is a statistically consistent distance-based method to reconstruct a phylogenetic tree from an alignment of molecular data. In 2000, Pauplin showed that the BME method is equivalent to optimizing a linear functional over the BME polytope, the convex hull of the BME vectors obtained from Pauplin's formula applied to all binary trees. The BME method is related to ...

A non-empty word w is a border of u if |w|<|u| and both prefix suffix u. privileged |u|≤1 or has that appears exactly twice in Peltomäki (2016) presented the following open problem: “Give nontrivial upper bound for B(n)”, where B(n) denotes number words length n. Let ln[0]⁡(n)=n let ln[j]⁡(n)=ln⁡(ln[j−1]⁡(n)), j,n are positive integers. We show q>1 size alphabet j≥3 an integer then there consta...

N, N-Dimethyl proteins were prepared by reductive methylation of their amino groups with formaldehyde and NaBH4. Proteolysis of these alkylated proteins by trypsin, or-chymotrypsin, subtilisin, pepsin, and fungal protease was determined by direct measurement of the bonds split, with the use of trinitrobenzenesulfonic acid to determine directly the appearance of new terminal amino groups. The lo...
