Controlling variation in the comet assay [PDF]

open access: yesFrontiers in Genetics, 2014
Variability of the comet assay is a serious issue, whether it occurs from experiment to experiment in the same laboratory, or between different laboratories analysing identical samples. Do we have to live with high variability, just because the comet assay is a biological assay rather than analytical chemistry? Numerous attempts have been made to limit

Supervised Machine Learning with Control Variates for American Option Pricing

open access: yesFoundations of Computing and Decision Sciences, 2018
In this paper, we make use of a Bayesian (supervised learning) approach in pricing American options via Monte Carlo simulations. We first present Gaussian process regression (Kriging) approach for American options pricing and compare its performance in ...

Corn Silage as a Total Diet with by-Products of the Babassu Agroindustry in the Feed of Confined Ruminants

open access: yesAgronomy, 2023
This study aimed to evaluate the chemical composition of total ration silage (TRS) containing two babassu by-products to replace the corn. The silages were formulated to meet the requirements of sheep for an average daily gain of 200 g/day.

Vector-Valued Control Variates

open access: yes, 2021
Control variates are variance reduction tools for Monte Carlo estimators. They can provide significant variance reduction, but usually require a large number of samples, which can be prohibitive when sampling or evaluating the integrand is computationally expensive.

Optimal Control of Variational Inequalities [PDF]

open access: yesCommunications in Information and Systems, 2010
We consider control problems for the variational inequality describing a single degree of freedom elasto-plastic oscillator. We are particularly interested in finding the "critical excitation", i.e., the lowest energy input excitation that drives the system between the prescribed initial and final states within a given time span.

Association of vitamin D receptor gene variants with polycystic ovary syndrome: a meta-analysis

open access: yesBMC Medical Genetics, 2019
Background Polycystic ovary syndrome (PCOS) is a common endocrine disorder in reproductive-age women. Multiple susceptible gene as well as environmental factors and their interaction each other are contributed to the PCOS risk.

Being a morning man has causal effects on the cerebral cortex: a Mendelian randomization study

open access: yesFrontiers in Neuroscience, 2023
IntroductionNumerous studies have suggested a connection between circadian rhythm and neurological disorders with cognitive and consciousness impairments in humans, yet little evidence stands for a causal relationship between circadian rhythm and the ...
