Biomass partitioning and growth efficiency in four naturally regenerated forest tree species [PDF]
, 2010 Current forest growth models and yield tables are almost exclusively based on data from mature trees, reducing their applicability to young and developing stands.

Aging Gracefully: A New Model of Microtubule Growth and Catastrophe [PDF]
Biophysical Journal, 2015 Although dynamic instability has beenstudied for 30 years, the structural de-tails and molecular mechanisms thatunderliemicrotubulegrowthandcatas-trophe are still hotly debated (1). Mi-crotubules play defining roles in cellshape and stiffness, they are targetsof anticancer drugs, and they cangenerate mechanical forces in boththeir growing and shrinking ...

Comparison of Some Nonlinear Functions for Describing Broiler Growth Curves of Cobb500 Strain [PDF]
Poultry Science Journal, 2019 This study was conducted to compare some nonlinear functions to describe the broiler growth curve of the Cobb500 strain. A flock of fifty one-day-old chicks were randomly selected from a henhouse of 2500 chicks.

ICT and Productivity Resurgence: A Growth Model for the Information Age [PDF]
The B.E. Journal of Macroeconomics, 2007 Since the mid-1990s, extraordinary advances in semiconductors have enhanced the embodied nature of information technology, fuelling efficiency growth in computers and communication equipment industries. The consequent fall in prices has enabled the rapid diffusion of these new technologies, which have reached the critical threshold to foster ...

Evolution of size-dependent flowering in Onopordum illyricum: A quantitative assessment of the role of stochastic selection pressures [PDF]
, 1999 We explore the evolution of delayed, size-dependent reproduction in the monocarpic perennial Onopordum illyricum, using a range of mathematical models, parameterized with long-term field data.

Individual tree basal area growth models for Chir pine (Pinus roxberghii Sarg.) in western Nepal
Journal of Forest Science, 2015 The individual tree growth models are important decision-making tools in forestry. Age dependent and age independent individual tree basal area growth models were developed for Chir pine (Pinus roxberghii Sarg.) in one of the western districts, Rukum ...

Comparison of four nonlinear growth models in Creole chickens of Mexico
Poultry Science, 2020 Animal growth is a complex and dynamic process that involves physiological and morphological changes from hatching to maturity. It is defined as the increase in body size per time unit.

Multi-Model Approach on Growth Estimation and Association With Life History Trait for Elasmobranchs
Frontiers in Marine Science, 2021 Age and growth information is essential for stock assessment of fish, and growth model selection may influence the accuracy of stock assessment and subsequent fishery management decision making.
