Basing on the ideas used by Kiselev, we study Hayward black hole surrounded quintessence. By setting for quintessence state parameter at special case of $\omega=-\frac{2}{3}$, using metric and definition effective potential, analyzed in detail null geodesics different energies. We also horizons as well shadow hole.

In light of the growing interest in Hayward black hole solution, a detailed study on corresponding lapse function and its roots is presented. The expressed terms classical Schwarzschild radius $r_s$ Hayward's parameter $l$. Both these quantities are used as thermodynamic variables to find related quantities. this context, variable $l$ associated with canonical conjugate $\mathcal{F}_H$, free en...

The plant growth regulator ethylene controls the onset of ripening in climacteric fruit (Schuch et al., 1989). Two enzymes are responsible for ethylene biosynthesis from its precursor S-adenosyl methionine: ACC synthase and ACC oxidase (Yang and Hoffman, 1984). Two cDNA clones, pTOM13 and pHTOM5, have been isolated from tomato and shown to encode ACC oxidase by expression in yeast (Hamilton et ...

The Hayward Tuning Vine is a software interface for exploring the system of microtonal tuning known as Just Intonation. Based ultimately on prime number relationships, harmonic space in Just Intonation is inherently multidimensional, with each prime number tracing a unique path in space. Taking this multidimensionality as its point of departure, the Tuning Vine interface assigns a unique angle ...

At the outset we should emphasize that nothing in Hayward and Tarr’s commentary speaks to the main results of the Biederman and Bar (1999) report: Slight costs of rotation in detecting geon differences when matching a sequential pair of novel objects (3.3% increase in error rates), but massive costs (46.2% increase in error rates) in the detection of metric differences. Their comments are all a...

RAND working papers are intended to share researchers' latest findings and to solicit informal peer review. They have been approved for circulation by RAND Infrastructure, Safety, and Environment but have not been formally edited or peer reviewed. Unless otherwise indicated, working papers can be quot...

Motivated by Dark Energy (DE) activities, we study certain physical behaviors of the quintessential Hayward-AdS black holes in four dimensions. We generalize some properties ordinary Hayward AdS without dark sector. elaborate a terms new quantities $c$ and $\omega_q$ parametrizing sector moduli space. investigate effect such parameters on thermodynamic optical aspects. To show behaviors, first ...
