The glioma longitudinal analysis (glass) consortium large-scale collaborations are needed to help us understand the impact of treatment on evolutionary dynamics and thereby develop novel treatments to prevent and overcome resistance to treatment. Furthermore, evolutionary modeling combined with frequent serial sampling of cfdna allows prediction of the expected time to treatment failure in individual patients. The q2-longitudinal plugin incorporates multiple methods for analysis of longitudinal and paired-sample data, including paired differences and distances, linear mixed effects models, microbial interdependence test, first differencing, and volatility analyses.

This study presents a longitudinal analysis of patterns of investment in advanced manufacturing technologies (amt) and financial performance investments in amt from 112 manufacturing plants in the metal-working industries are examined.
Abstract this article critiques the artificiality of the context-free and a historical approaches to theorising the evolution of property it starts with an overview of a number of evolutionary accounts, underpinned by different theories of institutions and institutional change, in the 'old' and 'new' institutional economics. Panel studies are a particular design of longitudinal study in which the unit of analysis is followed at specified intervals over a long period, often many years the key feature of panel studies is that they collect repeated measures from the same sample at different points in time most panel. Abstract this chapter proposes an iterative statistical approach, based on the principles of stepwise and segmented regression, to detect and quantify evolutionary trends and revolutionary changes (breakpoints) in long-term processes.
The e coli long-term evolution experiment (ltee) is an ongoing study in experimental evolution led by richard lenski that has been tracking genetic changes in 12 initially identical populations of asexual escherichia coli bacteria since 24 february 1988. Analysis of shape changes necessitates the development of models for dealing with manifold-valued longitudinal data such models would also beneﬁt other applications that in. The fate of pollutants in rivers is mainly affected by the longitudinal dispersion coefficient (kx) thus, improved kx estimation could greatly enhance the water quality management of rivers in. Analysis of longitudinal data also known as panel data in either case the data consist of repeated advances in evolutionary developmental biology.
