Probability of Default Estimation for Commercial Lenders in Developing Economies: Creditworthiness of Consumer Borrower
(Global Scientific Journals, 2019-06)The Business of advancing credits is gradually becoming a major target for many banks, as a result there is high competition among the financial institutions leading to default of most credits. In order to raise the quality ... -
Knockdown of Ghalba_4 and Ghalba_5 Proteins in Cotton Inhibits Root Growth and Increases Sensitivity to Drought and Salt Stresses
(Frontiers, 2019-10-15)We found 33, 17, and 20 Alba genes in Gossypium hirsutum, Gossypium arboretum, and Gossypium raimondii, respectively. The Alba protein lengths ranged from 62 to 312 aa, the molecular weight (MW) from 7.003 to 34.55 kDa, ... -
A Logistic Nonlinear Black-Scholes-Merton Partial Differential Equation: European Option
(International Journal of Research - GRANTHAALAYAH, 2018-06-30)Nonlinear Black-Scholes equations provide more accurate values by taking into account more realistic assumptions, such as transaction costs, illiquid markets, risks from an unprotected portfolio or large investor's ... -
Volatility Estimation Using European-Logistic Brownian Motion with Jump Diffusion Process
(International Journal of Mathematics And its Applications, 2020)Volatility is the measure of how we are uncertain about the future of stock or asset prices. Black-Scholes model formed the foundation of stock or asset pricing. However, some of its assumptions like constant volatility ... -
Genome wide identification of the trihelix transcription factors and overexpression of Gh_A05G2067(GT-2), a novel gene contributing to increased drought and salt stresses tolerance in cotton
(John Wiley & Sons Ltd, 2019-01)We identified 102, 51 and 51 proteins encoded by the trihelix genes in Gossypium hirsutum, Gossypium arboretum and Gossypium raimondii, respectively. RNA sequence data and real-time quantitative polymerase chain reaction ... -

Lie Symmetry Analysis of Modified Diffusive Predator-prey Competition System of Equations
(International Journal Of Multidisciplinary Sciences And Engineering, 2020-03)The predator-prey equations were developed and used by Lotka and Volterra to analyze the dynamics of biological systems in which two species interact, one as a predator and the other as prey [3]. Several attempts have been ... -
Use of Infinitesimal Transformations in obtaining the Generator of a harmonic fourth order non-linear ordinary differential equation.
(International Journal of Engineering& Scientific Research, 2017-05-05)Lie group Theory is applied to differential equations occurring as mathematical models [4]. This paper seeks to obtain a generator T for a harmonic fourth order non-linear ordinary differential equation using the Lie ... -
Integrated Approach to Wetland Protection: A Sure Means for Sustainable Water Supply to Local Communities of Nyando Basin, Kenya
(The International Journal of Engineering and Science (IJES), 2017)Wetlands have a buffering role particularly the ones at the lake shore, functioning like living filters by removing dissolved and suspended pollutants, thereby contributing to keeping lake waters clean and clear. They also ... -
