Tumour growth has been shown to approximate to the exponential in human cancers and, in general, the doubling times range from weeks to months. In contrast, the replicative processes at the cellular level, the cell cycle is completed within a time interval of a few tenths of hours in the majority of cell types.

Central to Keynes's indictment of classical economic analysis is the fundamental Keynesian proposition: a monetaty economy will not in general tend towards filll employment unaided by government policy. Analysis of this proposition in the context of conventional static macroeconomic theory is surely a prologue at best; examining models in which ...

Dynamic scaling in polycrystalline growth
Physical Review B, 1992The dynamic scaling properties of a polycrystalline growth model proposed by Van der Drift are discussed. We present an analytic derivation of the dynamic exponent, describing the growth of monocrystalline surface domains, yielding p=1/2 and 1/4 for two and three dimensions, respectively.

Strategic management of dynamic growth
Long Range Planning, 2017Abstract A great deal of theoretical and empirical work has been performed on firm growth following Edith Penrose's (1959) classic book, but there is growing concern among researchers and practitioners about the relevance of research as the business environment becomes increasingly dynamic.

Dynamic instability of microtubule growth
Nature, 1984We report here that microtubules in vitro coexist in growing and shrinking populations which interconvert rather infrequently. This dynamic instability is a general property of microtubules and may be fundamental in explaining cellular microtubule organization.

Mathematical modeling furnishes valuable and otherwise unattainable insights, some counterintuitive, into the natural history of lung cancer. We modeled lung cancer growth dynamics to show that: (1) early diagnosis of lethal lung cancer by means of radiographic or CT screening is an unattainable goal.

Single polymer growth dynamics
Science, 2017Watching growth, step by step Polymers can grow through the stepwise addition of monomers to an active end site. One might think that this would happen in a continuous linear process. With a focus on ring-opening metathesis polymerization of norbornene catalyzed by a Grubbs' catalyst, Liu et al.

Group dynamics and growth strategies
2008The object of this study is to analyse the particular evolutionary pattern of growth of many small- and medium-sized enterprises (SMEs) towards the formation of business groups.

Growth dynamics of an amphibian tissue
Journal of Cellular Physiology, 1966AbstractBy the “labeled mitoses” method of Quastler and Sherman and others, the cell cycle of the germinative zone cells of the bullfrog lens epithelium has been characterized. It has been shown that this cycle lasts approximately 83 days with the DNA synthetic phase enduring 100 hours and G2, 11 hours. G1 occupies over 90% of the total time.
