Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The hybrid nanofluid integrated with micropolar fluid shows growing interest due to the enhanced thermal performance in microscale devices. These improved properties are due to their greater thermal conductivity and rotational effects. The proposed study assesses the significance of velocity slip on the flow characteristic of micropolar ...

On the sum of the first n prime numbers [PDF]
, 2014 In this paper we establish a general asymptotic formula for the sum of the first n prime numbers, which leads to a generalization of the most accurate asymptotic formula given by Massias and Robin in 1996.Comment: 5 ...

Asymptotic Formulas for Some Arithmetic Functions [PDF]
Canadian Mathematical Bulletin, 1958 Let f(x) be an increasing function. Recently there have been several papers which proved that under fairly general conditions on f(x) the density of integers n for which (n, f(n)) = 1 is 6/π2 and that (d(n) denotes the number of divisors of n)In particular both of these results hold if f(x) = xα, 0 < α < 1 and the first holds if f(x) = [α x], α ...

Asymptotic unboundedness of the norms of delayed matrix sine and cosine
Electronic Journal of Qualitative Theory of Differential Equations, 2017 In the paper, the asymptotic properties of recently defined special matrix functions called delayed matrix sine and delayed matrix cosine are studied. The asymptotic unboundedness of their norms is proved.

An Alternative Approach to Spontaneous Photon Triplets Generation
Advanced Physics Research, EarlyView.Day by day, communication and computing technologies are progressing at a lightning speed, which is particularly true of the quantum version of these technologies (QIST). Increasingly, these technologies are emerging from unusual and sometimes bewildering quantum optical effects, which are based on exotic quantum physical theories.

The effective use of remainder term estimation in the limit theorems
Lietuvos Matematikos Rinkinys, 2003 We investigate the asymptotic behavior of mean value of multiplicative arithmetic function from the class M1(G). In the present paper the asymptotic formula under special condition on prime elements of Knopfmacher’s semigroup G is obtained.

Existence, Uniqueness and Asymptotic Behavior of Solutions for Semilinear Elliptic Equations
MathematicsA class of semilinear elliptic differential equations was investigated in this study. By constructing the inverse function, using the method of upper and lower solutions and the principle of comparison, the existence of the maximum positive solution and ...

The Anatomical Record, EarlyView.Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.
