Cassini-oval description of atomic binding: New insights into the quantitative relationship between hardness coefficient and bond energy energy [PDF]

PLOS ONE
In this paper, the research hypothesis of conservation of hardness coefficient is put forward, and a mathematical formula for describing and analyzing the relationship between hardness coefficient and bond energy is established in this model. The binding process of two heteronuclear atoms can be represented by Cassini oval in dynamic form, every ...

Rotational modulation and local time dependence of Saturn's infrared H3+ auroral intensity [PDF]

, 2012
Planetary auroral emissions reveal the configuration of magnetospheric field-aligned current systems. In this study, Cassini Visual and Infrared Mapping Spectrometer (VIMS) observations of Saturn's pre-equinox infrared H3+ aurorae were analysed to show ...

Cassini observations of ion and electron beams at Saturn and their relationship to infrared auroral arcs [PDF]

, 2012
We present Cassini Visual and Infrared Mapping Spectrometer observations of infrared auroral emissions from the noon sector of Saturn's ionosphere revealing multiple intense auroral arcs separated by dark regions poleward of the main oval.

Polypolar coordination and symmetries [PDF]

Компьютерные исследования и моделирование, 2010
The polypolar system of coordinates is formed by a family of a parametrized on a radius isofocal of kf-lemniscates. As well as the classical polar system of coordinates, it characterizes a point of a plane by a polypolar radius and polypolar angle . For

Brauer-Type Inclusion Sets of Zeros for Chebyshev Polynomial

Mathematics, 2019
The generalized polynomials such as Chebyshev polynomial and Hermite polynomial are widely used in interpolations and numerical fittings and so on. Therefore, it is significant to study inclusion regions of the zeros for generalized polynomials.

Location of Saturn's northern infrared aurora determined from Cassini VIMS images [PDF]

, 2011
The location of Saturn's northern infrared aurora is described in detail using 12 selected images acquired by Cassini VIMS during 2006–2008. Bright main oval arcs and prevalent polar features are displayed, which do not exhibit a preferred local time or ...

Simultaneous Cassini VIMS and UVIS observations of Saturn's southern aurora: Comparing emissions from H, H-2 and H-3(+) at a high spatial resolution [PDF]

, 2011
Here, for the first time, temporally coincident and spatially overlapping Cassini VIMS and UVIS observations of Saturn's southern aurora are presented. Ultraviolet auroral H and H-2 emissions from UVIS are compared to infrared H-3(+) emission from VIMS ...

Properties of Inverted Cassini Ovals and their Surfaces: Constant Oriented Angle Sums [PDF]

, 2022
In classical geometry, an Apollonian cubic is the locus of points that view two segments at oriented angles which sum to zero or pi radians. In this work we extend this idea to any angle and find, in general, the resulting curve is a Cassini oval ...

Electroacoustic single-cell spectroscopy for morphological differentiation of red blood cells: An in silico feasibility study [PDF]

JASA Express Letters
A computational electroacoustic framework is presented for morphology-dependent characterization of single red blood cells. Electric fields obtained via finite-element modeling were converted into initial electroacoustic pressure sources and propagated ...

A subclass of strongly starlike functions [PDF]

ریاضی و جامعه
Let's denote $\mathcal{S}^{\ast}(f_c)$ as a family of analytic functions $f(z)=z+a_2z^2+a_3z^3+\cdots$ in the open unit disk $\mathbb{D}$ that satisfy the following relation for $c\in (0,1)$:$$\frac{zf'(z)}{f(z)}\prec f_c(z)=\frac{1}{\sqrt{1-cz}}, \quad ...
