The authors define a new subclass of A of functions involving complex order in the open unit disk U. For this new class, we obtain certain inclusion properties involving the Gaussian hypergeometric functions. [ABSTRACT FROM AUTHOR]

Abstract: Making use of a certain linear operator, which is defined here by means of the Hadamard product (or convolution), we introduce two novel subclasses of the class of normalized -valent analytic functions in the open unit disk. The main objective of the present paper is to investigate the various important properties and characteristics of each of these subclasses. Furthermore, several properties involving neighborhoods of functions in these subclasses are investigated. We also derive many results for the modified Hadamard products of functions belonging to the class . Finally, some applications of fractional calculus operators are considered.

Neuroendocrine adjustments to maximal and submaximal exercise were investigated in men as a function of age and training status. Twenty-four trained cyclists and 23 sedentary men constituting a young (M = 22.9 yrs, n = 16), middle-aged (M = 44.9 yrs, n = 16), and old (M = 65.5 yrs, n = 15) group performed both a maximal (GXT) and a 45-minute submaximal exercise test (cycle ergometer) at the workload corresponding to their lactate threshold. Plasma lactate, glucose, growth hormone, cortisol, norepinephrine, and epinephrine concentrations were analyzed both at rest and during exercise. Peak oxygen consumption (VO2 peak) was lower with age; however, all trained groups had higher values for VO2 peak compared to sedentary groups, regardless of age. Lactate threshold, when expressed in absolute terms, was lower with advancing age (sedentary decreases 9 and 26%: trained decreases 19 and 35% for middle-age and old, respectively, when compared to young). Pre-exercise plasma norepinephrine levels were higher with age in both trained and sedentary subjects. Cortisol levels were lower with age for sedentary subjects and were significantly elevated in trained subjects across all age groups. Endurance training resulted in increased hormonal responses, as measured by plasma concentrations, to both maximal and submaximal exercise across all age groups. However, regardless of training status, age-related declines were observed in peak responses for lactate, growth hormone, and cortisol during the GXT. During the 45-minute submaximal exercise test, these age-related differences that had been present in the GXT were abolished. This submaximal test represented a lower absolute work load for old compared to young as well as sedentary compared to trained subjects; however, individuals were working at similar relative exercise intensities. We conclude that older individuals are capable of similar hormonal responses to submaximal exercise of identical durations and intensities as their young and middle-aged counterparts, and that chronic endurance training can enhance the hormonal response to exercise in all age groups.

We derive subordination and superordination results for a family of normalized analytic functions in the open unit disk defined by integral operators. We apply this to obtain sandwich results and generalizations of some known results. [ABSTRACT FROM AUTHOR]

Ruscheweyh and Sheil-Small proved the Po´lyarSchoenberg conjecture that the class of convex analytic functions is closed under convolution or Hadamard product. They also showed that close-to-convexity is preserved under convolution with convex analytic functions. In this note, we investigate harmonic analogs. Beginning with convex analytic functions, we form certain harmonic functions which preserve close-to-convexity under convolution. An auxiliary function enables us to obtain necessary and sufficient convolution conditions for convex and starlike harmonic functions, which lead to sufficient coefficient bounds for inclusion in these classes.
