Many researchers have been working on recurrence relation which is an important topic not only in mathematics but also physics, economics and various applications computer science. There are many useful results sequence there main problem to find any term of we need all previous terms sequence. were theorems obtained relations. In this paper given special identity for generalized kth order rela...

background: despite more than a decade experience of annual student congresses in iran, major scientific writing weakness still exists in students’ abstracts submitted to the annual research congress of iran’s medical sciences students (arcimss). assessment of these abstracts can provide information on common scientific writing errors and subsequent development of abstract quality for the futur...

We determined the power and its graph simulations on discrete Poisson Chi-square distributions. There are four important steps of research methodology summarized as follow: (1) determine sufficient statistics (if possible), (2) create rejection area (UMPT test is sometime used), (3) derive formula power, (4) graphs using data (in simulation). The their curves then created <img src=image/1342768...

the aim of this study was to estimate suspended sediment by the ann model, dt with cart algorithm and different types of src, in ten stations from the lorestan province of iran. the results showed that the accuracy of ann with levenberg-marquardt back propagation algorithm is more than the two other models, especially in high discharges. comparison of different intervals in models showed that r...

The research is devoted to the actual problem of harmony ecological development in conditions circular economy formation. aim study develop methodological principles for determining environmental To achieve this goal, main concept were identified, a step-by-step approach assessing was developed and proposed developments tested on example regions Ukraine. Harmony formation gives chance define ce...

From the last few years, generalized bent functions gain a lot of attention in research as they have many applications various fields such combinatorial design, sequence design theory, cryptography, CDMA communication, etc. A deep and broad study with their properties is done literature. Kumar et al.[11] first gave concept function. Many researchers studied characterizations functions. In [2] a...

A dynamical model for COVID-19 spread relating to non-pharmaceutical interventions and vaccination is mathematically generated by adding a gradual compartment the susceptible population considering only symptomatic infectious stage. In our model, there are seven compartments dividing given into , vaccinated src=image/17628733_02.gif>, exposed src=image/17628733_03...

SRC kinases and PKR are intracellular protein kinases, which play key roles in intracellular viral replication. In this research, the effect of SRC kinase inhibition and PKR activation and inhibition on replication of coxsakievirus (CVB3), an entrovirus of the family picornaviridae – causative agents of fatal myocarditis, was studied. Vero and Hela cells were cultured and infected with CVB3 in ...

The present article derives the minimal number N of observations needed to approximate a Bayesian posterior distribution by Gaussian. derivation is based on an invariance requirement for likelihood .
