Exponential Growth of Solutions for Nonlinear Coupled Viscoelastic Wave Equations
Universal Journal of Mathematics and Applications, 2019 In this work, we consider an initial-boundary value problem related to the nonlinear coupled viscoelastic equations \[ \left\{ \begin{array}{c} \left\vert u_{t}\right\vert ^{j}u_{tt}-\Delta u_{tt}-div\left( \left\vert \nabla u\right\vert ^{\alpha -2 ...

bioRxiv, 2019 Models of cancer cell population expansion assume exponential growth kinetics at low cell densities, with deviations from exponential growth only at higher densities due to limited resources such as space and nutrients.

Bound on the exponential growth rate of out-of-time-ordered correlators. [PDF]
Physical Review E, 2017 It has been conjectured by Maldacena, Shenker, and Stanford [J. Maldacena, S. H. Shenker, and D. Stanford, J. High Energy Phys. 08 (2016) 10610.1007/JHEP08(2016)106] that the exponential growth rate of the out-of-time-ordered correlator (OTOC) F(t) has a

Control and maintenance of mammalian cell size
BMC Cell Biology, 2004 Background Conlon and Raff propose that mammalian cells grow linearly during the division cycle. According to Conlon and Raff, cells growing linearly do not need a size checkpoint to maintain a constant distribution of cell sizes.

On exponential growth and uniformly exponential growth for groups
Inventiones Mathematicae, 2004 The paper gives a negative answer to \textit{M. Gromov}'s question [Structures métriques pour les variétés riemanniennes. Textes Mathématiques, 1. Paris (1981; Zbl 0509.53034)], (Remark 5.2) posed in 1981. Gromov asked `if groups of exponential growth necessarily have uniform exponential growth'.

Models for plant self‐thinning
Ecosphere, 2018 Plant self‐thinning, which is density‐dependent mortality, has several observed characteristics, including a certain mathematical relationship between growth and density. The original equation that describes self‐thinning is logw¯=C−(3/2)×logdensity, w¯ =

The Human Ecology of Overshoot: Why a Major ‘Population Correction’ Is Inevitable
World, 2023 Homo sapiens has evolved to reproduce exponentially, expand geographically, and consume all available resources. For most of humanity’s evolutionary history, such expansionist tendencies have been countered by negative feedback.
