Analysis of logistic growth models [PDF]
, 2001 A variety of growth curves have been developed to model both unpredated, intraspecific population dynamics and more general biological growth. Most successful predictive models are shown to be based on extended forms of the classical Verhulst logistic ...

Magnetar powered GRBs: Explaining the extended emission and X-ray plateau of short GRB light curves
, 2013 Extended emission (EE) is a high-energy, early time rebrightening sometimes seen in the light curves of short gamma-ray bursts (GRBs). We present the first contiguous fits to the EE tail and the later X-ray plateau, unified within a single model.

Broadband modelling of short gamma-ray bursts with energy injection from magnetar spin-down and its implications for radio detectability [PDF]
, 2015 The magnetar model has been proposed to explain the apparent energy injection in the X-ray light curves of short gamma-ray bursts (SGRBs), but its implications across the full broadband spectrum are not well explored.

Colonization and spatiotemporal distribution of bruchid pests in lentil and faba bean fields
Pest Management Science, EarlyView.This study of 104 fields identifies Bruchus signaticornis in lentils and B. rufimanus in faba beans as the sole grain‐damaging species. Their uniform distribution within fields and the strong effect of regulatory factors on larvae and egg survival emphasize the need for species‐specific, phenology‐based and spatially informed integrated pest management

On the Construction of Some Fractional Stochastic Gompertz Models
Mathematics, 2020 The aim of this paper is the construction of stochastic versions for some fractional Gompertz curves. To do this, we first study a class of linear fractional-integral stochastic equations, proving existence and uniqueness of a Gaussian solution.

Bootstrap Resampling in Gompertz Growth Model with Levenberg–Marquardt Iteration
JTAM (Jurnal Teori dan Aplikasi Matematika), 2022 Soybean plants have limited growth with a planting period of 12 weeks, which causes the observed sample to be very small. A small sample of soybean plant growth observations can be bias causes in the conclusion of prediction results on soybean plant ...

Assessing pest control treatments from phenology models and field data
Pest Management Science, Volume 81, Issue 4, Page 1851-1859, April 2025.Theoretical effect of two larvicide sprays, two delayed larvicide sprays that follow an oil treatment, mating disruption, and mating disruption plus four virus sprays on codling moth larva (brown for treated versus pink for untreated) and adult (dark green for treated versus light green for untreated) phenology.

A reaction-diffusion model for the growth of avascular tumor
, 2001 A nutrient-limited model for avascular cancer growth including cell proliferation, motility and death is presented. The model qualitatively reproduces commonly observed morphologies for primary tumors, and the simulated patterns are characterized by its ...
