On the analyzing of bifurcation properties of the one‐dimensional Mackey–Glass model by using a generalized approach

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.

Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...

Presynaptic Congenital Myasthenic Syndromes

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Presynaptic congenital myasthenic syndromes (CMS) encompass a large number of rare neurologic disorders caused by impaired release of acetylcholine (ACh) from motor nerve terminals. There are two main groups of presynaptic CMS: one in which the amount of ACh in synaptic vesicles (SV) is diminished and another in which the mechanism of synaptic

The hunt for Scabiosa trenta Hacq: how the pursuit of a phantom ignited a passion for botany and mountaineering

open access: yesNordic Journal of Botany, EarlyView.
Scabiosa trenta Hacq. was first described in 1782 by Balthasar Hacquet, with its specific epithet referring to the Trenta Valley in Slovenia. Since then, S. trenta has been the focus of numerous mountaineering and botanical expeditions, particularly by the alpinist Julius Kugy during the Golden Age of Alpinism, a period in the second half of 19th ...
