On a subfamily of starlike functions related to hyperbolic cosine function

open access: yesThe Journal of Analysis, 2023
We introduce and study a new Ma-Minda subclass of starlike functions $\mathcal{S}^*_{\varrho},$ defined as $$\mathcal{S}^{*}_{\varrho}:=\left\{f\in\mathcal{A}:\frac{zf'(z)}{f(z)} \prec \cosh \sqrt{z}=:\varrho(z), z\in\mathbb{D} \right\},$$ associated with an analytic univalent function $\cosh \sqrt{z},$ where we choose the branch of the square root ...

Point-Symmetric Extension-Based Interval Shannon-Cosine Spectral Method for Fractional PDEs

open access: yesDiscrete Dynamics in Nature and Society, 2020
The approximation accuracy of the wavelet spectral method for the fractional PDEs is sensitive to the order of the fractional derivative and the boundary condition of the PDEs.

ON GENERALIZED SINE AND COSINE FUNCTIONS

open access: yesDemonstratio Mathematica, 1995
The author finds addition formulas for functions \(f\), \(g\) which satisfy the functional equation \((f (x))^n+ (g (x))^n =1\), where \(f\), \(g\) are supposed to be real functions on a given group \((X, +)\) and \(n\in \mathbb{N}\) is fixed. The obtained addition formulas coincide with the well known representations of \(\cos (x+y)\) and \(\sin (x+y)\

Status of the COSINE-100 Experiment

open access: yes, 2018
Presently a number of experiments are operating to search for the WIMP, a dark matter candidate. Among these experiments, DAMA/LIBRA claims to observe an annually modulated WIMP signal, while other experiments, using different technologies and target ...

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

open access: yesFEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

On the Superstability Related with the Trigonometric Functional Equation

open access: yesAdvances in Difference Equations, 2009
We will investigate the superstability of the (hyperbolic) trigonometric functional equation from the following functional equations: , , , , which can be considered the mixed functional equations of the sine function and cosine function, of the ...

An Implementation of Inverse Cosine Hardware for Sound Rendering Applications

open access: yesSensors, 2023
Sound rendering is the process of determining the sound propagation path from an audio source to a listener and generating 3D sound based on it. This task demands complex calculations, including trigonometric functions. This paper presents hardware-based

Identification and characterisation of calcitonin receptor isoforms expressed in glioblastoma derived glioma stem and U‐87 MG cells

open access: yesFEBS Open Bio, EarlyView.
Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...
