Architectures and complex functions of tandem riboswitches [PDF]

open access: yesRNA Biology, 2022
Riboswitch architectures that involve the binding of a single ligand to a single RNA aptamer domain result in ordinary dose-response curves that require approximately a 100-fold change in ligand concentration to cover nearly the full dynamic range for ...

Approximation of Directional Step Derivative of Complex-Valued Functions Using a Generalized Quaternion System

open access: yesAxioms, 2021
The step derivative of a complex function can be defined with various methods. The step direction defines a basis that is distinct from that of a complex number; the derivative can then be treated by using Taylor series expansion in this direction.

Stress state of protective shells in the area of holes due to prestressed reinforcement curvature [PDF]

open access: yesИнженерно-строительный журнал, 2017
The stress state around the holes in cylindrical part of prestressed concrete protective shells is examined in this paper. This stress state is caused by general shell prestressing having the aim to compensate internal emergency pressure and the ...

Ansatz and Averaging Methods for Modeling the (Un)Conserved Complex Duffing Oscillators

open access: yesMathematics, 2023
In this study, both the ansatz and averaging methods are carried out for analyzing the complex Duffing oscillators including the undamped/conserved complex Duffing oscillator (CDO) and the damped/unconserved CDO to obtain some approximate analytical ...

Pre-functions and Extended pre-functions of Complex Variables

open access: yesJournal of Nigerian Society of Physical Sciences, 2023
Pre-functions are functions that possess a sequence $\{f_{n}(z,\beta)\}$ which tends to one of the elementary functions as $n$ tends to infinity and $\beta$ tends to 0.

Understanding the mammalian TRAP complex function(s) [PDF]

open access: yesOpen Biology, 2020
In eukaryotic cells, about one-third of the synthesized proteins are translocated into the endoplasmic reticulum; they are membrane or lumen resident proteins and proteins direct to the Golgi apparatus.
