Bayesian estimation of student-t garch model using lindley's approximation
(Acad Economic Studies, 2019)
The dependency of conditional second moments of financial time series is modelled by Generalized Autoregressive conditionally heteroscedastic (GARCH) processes. The maximum likelihood estimation (MLE) procedure is most ...
A Mathematical modelling approach in the spread of the novel 2019 Coronavirus SARS-CoV-2 (COVID-19) pandemic
(Modestum Ltd, 2020)
The novel 2019 coronavirus, SARS-CoV-2 (COVID-19), emerged towards the end of 2019 in the city of Wuhan in the province of Hubei in the People's Republic of China, and it has spread to the entire world very fast and in a ...
Genome-wide differentiation in closely related populations: the roles of selection and geographic isolation
(Wiley, 2016)
Population divergence in geographic isolation is due to a combination of factors. Natural and sexual selection may be important in shaping patterns of population differentiation, a pattern referred to as 'isolation by ...
Global song divergence in barn swallows (Hirundo rustica): exploring the roles of genetic, geographical and climatic distance in sympatry and allopatry
(Oxford Univ Press, 2018)
Divergence in acoustic signals plays an important role in the production and maintenance of biodiversity in numerous taxa. In this study, we assess patterns of acoustic divergence in geographically isolated and sympatric ...
Numerical investigation of the effects of geometric structure of microchannel heat sink on flow characteristics and heat transfer performance
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2019)
A numerical study was performed to investigate the thermal-hydraulic performance of different microchannel heat sink (MCHS) designs for cooling channels in a lithium-ion battery including various geometric modifications. ...
Synthesis, characterization, and application of transition metals (Ni, Zr, and Fe) doped TiO2 photoelectrodes for dye-sensitized solar cells
(Elsevier, 2020)
In this paper, we present the synthesis of different metal-doped TiO2 compounds (pure TiO2, Fe doped TiO2 (FexTi1-xO2), Ni doped TiO2 (NixTi1-xO2), Zr doped TiO2 (ZrxTi1-xO2)) thin films in order to improve the performance ...
Mathematical modeling of packed bed and microwave drying of enriched couscous
(Springer, 2018)
In this study, the drying kinetics and modeling of enriched couscous with two different compositions (A and B) were carried out by using packed bed (60 and 80 A degrees C) and microwave (180 and 360 W) drying techniques. ...
Protective effects of N-acetyl cysteine against paclitaxel-induced cardiotoxicity through modulation of transient receptor potential melastatin 2 channels
(Gazi Univ, Fac Med, 2019)
Aim : In our study, we investigated the paclitaxel induced cardiotoxicity and alterations in Ca2+ influx, oxidative stress and apoptosis through transient receptor potential melastatin 2 (TRPM2) channels and modulator role ...
The effects of carvacrol on oxidative stress parameters and adoptosis process via TRPA1 channels in neuroblastoma cells
(Polskie Towarzystwo Farmaceutyczne, 2019)
Objectives: This study is a preliminary study to investigate the effects of carvacrol (CRV) obtained from thyme on the apoptosis process in neuroblastoma cells. Methods: In this study, seven groups were designed as control, ...
Fracture toughness enhancement of yttria-stabilized tetragonal zirconia polycrystalline ceramics through magnesia-partially stabilized zirconia addition
(Vietnam Natl Univ, 2020)
In this work, for the first time, we report a novel method on the fracture toughness enhancement of 3 mol % yttria-stabilized tetragonal zirconia polycrystalline (3Y-TZP) ceramics through the incorporation of 8 mol % ...
