On Spirallikeness of Entire Functions
MathematicsIn this article, we establish conditions under which certain entire functions represented as infinite products of their positive zeros are α-spirallike of order cos(α)/2. The discussion includes several examples featuring special functions such as Bessel,

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit
Contributions to Plasma Physics, EarlyView.ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

High accuracy trigonometric approximations of the real Bessel functions of the first kind [PDF]
, 2020 We construct high accuracy trigonometric interpolants from equidistant evaluations of the Bessel functions $J_n(x)$ of the first kind and integer order. The trigonometric models are cosine or sine based depending on whether the Bessel function is even or

On the variation with respect to a parameter of zeros of Bessel and q-Bessel functions
Journal of Mathematical Analysis and Applications, 1988 We apply what is essentially the Hellmann-Feynman theorem in a discrete setting to derive representations for the derivatives with respect to a parameter of the positive zeros of a family of entire functions. These representations prove that the zeros are monotone functions of the parameters involved. This family includes the Bessel functions \(J_{\nu}(

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Graphite nanofluids were stabilized using a mixed SDS/Tween 80 surfactant system. The optimized formulation exhibited enhanced colloidal stability, red‐shifted UV–Vis absorption, and improved photothermal conversion under solar irradiation. Achieving stable dispersion of graphite flakes (GFs) in aqueous media remains a critical challenge in developing ...

Univalence of certain integral operators involving q-Bessel functions
Filomat, 2019 In this investigation we make a systematic study of the univalence of certain families of integral operators, which are defined by means of the normalized forms of Jackson?s second and third q-Bessel functions.
