On the generalized proximate order of functions analytic on the unit disc
The concept of Lindel$ \ddot{o} $f proximate order has been used extensively to study the functions of completely regular growth. The main drawback of this approach is that it completely ignores the value of lower order. To overcome this problem, Chyzykov et al. introduced the concept of…

Slow Growth and Optimal Approximation of Pseudoanalytic Functions on the Disk
…considered the approximation of pseudoanalytic functions on the disk. Kumar et al. [9] studied the generalized order and generalized type of PAF in terms of the Fourier coefficients occurring in its local expansion and optimal approximation errors in Bernstein sense on the disk. The aim of this…

A computational technique for solving boundary value problem with two small parameters
In this article we study a singularly perturbed boundary-value problem for a delay differential equation with a small delay parameter in the first derivative term whose solution has a single boundary layer. The proposed method is shown to be stable, and its performance is confirmed with examples.

On Moment Generating Function of Generalized Order Statistics From Extended Type II Generalized Logistic Distribution
In this paper, explicit expressions and some recurrence relations are derived for marginal and joint moment generating functions of generalized order statistics from extended type II loglogistic distribution. Further the results are deduced for moments of k -- th record values and ordinary order…

Generalized growth and approximation errors of entire harmonic functions in \(R^n\), \(n \geq 3\)
In this paper we study the continuation of harmonic functions in the ball to the entire harmonic functions in space \(\mathbb{R}^n\), \(n\geq 3\). The generalized order introduced by M.N. Seremeta has been used to characterize the growth of such functions. Moreover, the generalized order…

On the Growth and Approximation of Transcendental Entire Functions on Algebraic Varieties
Let X be a complete intersection algebraic variety of codimension m > 1 in Cm+n. Inthis paper we characterized the classical growth parameters order and type for transcendental entire functions f ∈ ⊕(X), the space of holomorphic functions on the complete intersection algebraic variety X, in terms…

\(L^p\)-approximation and generalized growth of generalized biaxially symmetric potentials on hyper sphere
The generalized order of growth and generalized type of an entire function \(F^{\alpha,\beta}\) (generalized biaxisymmetric potentials) have been obtained in terms of the sequence \(E_n^p(F^{\alpha,\beta},\Sigma_r^{\alpha,\beta})\) of best real biaxially symmetric harmonic polynomial approximation…

On the Rational Approximation of Analytic Functions Having Generalized Types of Rate of Growth
The present paper is concerned with the rational approximation of functions holomorphic on a domain G⊂C, having generalized types of rates of growth. Moreover, we obtain the characterization of the rate of decay of product of the best approximation errors for functions f having fast and slow rates…

Hepatopulmonary fusion: a rare and potentially lethal association with right congenital diaphragmatic hernia
Hepatopulmonary fusion is an extremely rare accompaniment of right congenital diaphragmatic hernia. It is associated with abnormal systemic arterial supply and venous drainage of the right lung along with congenital heart disease. Children with this condition have a comparatively poor prognosis. We…

Management of long segment congenital esophageal stenosis: A novel technique
Congenital esophageal stenosis (CES) is a rare cause of dysphagia in children. Diagnosis is often apparent on esophagogram. Surgical treatment for the subtype with tracheobronchial remnants (TBR) includes resection and anastomosis of the stenosed segment, myectomy, enucleation of cartilage, etc…

Post-operative Adult Onset Tic Disorder: A Rare Presentation
Tics are rapid and repetitive muscle contractions resulting in stereotype movements and vocalizations that are experienced as involuntary. Onset before 18-year is a diagnostic criterion for tic disorders. Children and adolescents may exhibit tic behaviors after a stimulus or in response to an…
