Delay-differential-equation model for mode-locked lasers based on nonlinear optical and amplifying loop mirrors [PDF]

open access: yes, 2021
Delay differential equation model of a nonlinear optical-nonlinear amplifying loop mirror mode-locked laser is developed that takes into account the finite relaxation rate of the gain medium and asymmetric beam splitting at the entrance of the nonlinear ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

The nonnegativity of solutions of delay differential equations

open access: yesApplied Mathematics Letters, 2000
In this paper, the author proves the nonnegativity of solutions to delay equations of the type \[ x'(t)=F(x(t))+G(x(t-\tau)) \] under certain conditions. A few examples are discussed.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Competitive Lotka–Volterra population dynamics with jumps [PDF]

open access: yes, 2011
This paper considers competitive Lotka–Volterra population dynamics with jumps. The contributions of this paper are as follows. (a) We show that a stochastic differential equation (SDE) with jumps associated with the model has a unique global positive ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Stability implications of delay distribution for first-order and second-order systems [PDF]

open access: yes, 2009
In application areas, such as biology, physics and engineering, delays arise naturally because of the time it takes for the system to react to internal or external events.

Investigation of stability in a two-delay model of the ultradian oscillations in glucose-insulin regulation [PDF]

open access: yes, 2015
In this paper, a two-delay model for the ultradian oscillatory behaviour of the glucose-insulin regulation system is studied. Hill functions are introduced to model nonlinear physiological interactions within this system and ranges on parameters ...

A numerical technique for solving nonlinear singularly perturbed delay differential equations

open access: yesMathematical Modelling and Analysis, 2018
This paper presents a numerical technique for solving nonlinear singularly perturbed delay differential equations. Quasilinearization technique is applied to convert the nonlinear singularly perturbed delay differential equation into a sequence of linear
