Are most proposed ridge parameter estimators skewed and do they have any effect on MSE values?
(Taylor and Francis Ltd., 2021)
Multicollinearity is a common problem in multiple regression that occurs whenever two or more explanatory variables are highly correlated. When multicollinearity exists, the method of Ordinary Least
Square (OLS) is likely ...
Electrochemical sensor based on perylene diimide derivative modified electrode
(Springer, 2021)
A N,N’-Bis(1-isobutyl-1H-benzimidazole-2-yl)perylene-3,4,9,10-tetracarboxylic acid diimide (H1) modified carbon felt electrode has been prepared and applied for dopamine detection. Dopamine was chosen as the test analyte ...
Determining the Flat Sales Prices by Flat Characteristics Using Bayesian Network Models
(Springer, 2021)
There are various factors affecting flat sales prices. Various characteristics of a flat play an important role in determining its sales price. In this study, a machine learning based Bayesian network was built by a ...
Improvement effect of the MoO3 interface layer on the p- Si-based Schottky diode
(Springer, 2021)
The aim of this study is to compare the effects of the molybdenum trioxide (MoO3) used as an interface layer in a p-type Si-based metal–semiconductor (MS) junction with and without this layer. For this purpose, Al/p-Si and ...
Monitoring exponentially distributed time between events data: self-starting perspective
(TAYLOR & FRANCIS INC, 2021)
Time between events (TBE) control charts have been widely used to monitor high yield processes. Traditionally, an estimated in-control occurrence rate from a Phase I dataset is used to calculate the control limits when the ...
UPLC-ESI-MS/MS screening, potential of larvicide and antioxidant activity of bioactive compounds in gagea bohemica extracts
(Parlar Scientific Publications, 2020)
This work was designed to phenolic compound analysis with UPLC-ESI-MS/MS (Ultra Performance Liquid Chromatography-Tandem Mass Spectrometry), antioxidant and larvicidal (against Musca domestica and Culex pipiens) activities ...
Indirect dating of an olive tree planting event using luminescence of the sediments lying beneath the roots of the tree: a pilot study in the south-western part of Anatolia, Turkey
(John Wiley and Sons Ltd, 2020)
The aim of the present study is to attempt assessing the age of a monumental olive tree located between the Antique Cities of Militus (Didim-Aydın region) and Iasos (Milas-Muğla region). Wood from the trunk of an olive ...
Analogy between periodic patterns in thin smectic liquid crystal films and the intermediate state of superconductors
(Natl Acad Sciences, 2020)
Spontaneous breaking of symmetry in liquid crystal (LC) films often reveals itself as a microscopic pattern of molecular align-ment. In a smectic-A LC, the emergence of positional order at the transition from the nematic ...
Onosma pulchra: Phytochemical composition, antioxidant, skin-whitening and anti-diabetic activity
(Elsevier, 2020)
Researchers have discovered in recent years that some Onosma species have interesting biological/pharmacological activities. This study was conducted to investigate the antioxidant, tyrosinase and alpha-amylase inhibitor ...
Efficient photochemical vapor generation of bismuth using a coiled Teflon reactor: Effect of metal sensitizers and analytical performance with flame-in-gas-shield atomizer and atomic fluorescence spectrometry
(Elsevier Inc., 2021)
Photochemical vapor generation (PVG) of bismuth was accomplished in a simple flow–injection system with a standard Hg low-pressure tube lamp and a coiled Teflon reactor. The influence of a reaction medium flow rate ...
