Combining ultraconserved elements and mtDNA data to uncover lineage diversity in a Mexican highland frog (Sarcohyla; Hylidae) [PDF]

open access: yesPeerJ, 2018
Molecular studies have uncovered significant diversity in the Mexican Highlands, leading to the description of many new endemic species. DNA approaches to this kind of species discovery have included both mitochondrial DNA (mtDNA) sequencing and ...

Effects of fenofibrate on lipid parameters in obese rhesus monkeys

open access: yesJournal of Lipid Research, 2001
Fenofibrate is a member of the fibrate class of hypolipidemic agents used clinically to treat hypertriglyceridemia and mixed hyperlipidemia. The fibrates were developed primarily on the basis of their cholesterol and triglyceride lowering in rodents ...

Comparison of ultraconserved elements (UCEs) to microsatellite markers for the study of avian hybrid zones: a test in Aphelocoma jays

open access: yesBMC Research Notes, 2019
Objective Hybrid zones are geographic regions where genetically distinct taxa interbreed, resulting in offspring of mixed ancestry. California Scrub-Jays (Aphelocoma californica) and Woodhouse’s Scrub-Jays (A. woodhouseii) come into secondary contact and

On Sound Relative Error Bounds for Floating-Point Arithmetic

open access: yes, 2017
State-of-the-art static analysis tools for verifying finite-precision code compute worst-case absolute error bounds on numerical errors. These are, however, often not a good estimate of accuracy as they do not take into account the magnitude of the ...

Subgame perfect implementation with almost perfect information and the hold-up problem [PDF]

open access: yes, 2009
The foundations of incomplete contracts have been questioned using or extending the subgame perfect implementation approach of Moore and Repullo (1988). We consider the robustness of subgame perfect implementation to the introduction of small amounts of ...

Invers Moore-Penrose pada Matriks Turiyam Simbolik Real

open access: yesJambura Journal of Mathematics, 2023
The symbolic Turiyam matrix is a matrix whose entries contain symbolic Turiyam. Inverse matrices can generally be determined if the matrix is a non-singular square matrix. Currently the inverse of the symbolic Turiyam matrix of size m × n with m 6= n can

Finite Time Robust Control of the Sit-to-Stand Movement for Powered Lower Limb Orthoses

open access: yes, 2018
This study presents a technique to safely control the Sit-to-Stand movement of powered lower limb orthoses in the presence of parameter uncertainty. The weight matrices used to calculate the finite time horizon linear-quadratic regulator (LQR) gain in ...
