A Periodic Systems Toolbox for MATLAB [PDF]

open access: yes, 2005
The recently developed Periodic Systems Toolbox for MATLAB is described. The basic approach to develop this toolbox was to exploit the powerful object manipulation features of MATLAB via flexible andfunctionally rich high level m-functions, while ...

Variation in the diversity-productivity relationship in young forests of the eastern United States.

open access: yesPLoS ONE, 2017
The diversity-productivity relationship has not been studied as extensively in forests as in other ecosystems. We address this gap in our knowledge by examining the relationship of productivity (primarily the periodic annual increment in aboveground ...

Diameter growth prediction for individual Pinus occidentalis Sw. trees

open access: yesiForest - Biogeosciences and Forestry, 2013
Predictive equations calibrated with remeasurement data from 25 permanent plots having individually identified trees were used to project stem diameter of Pinus occidentalis Sw. in Dominican Republic. The general form of the models used to fit the growth

On computing inner-outer factorizations of periodic systems [PDF]

open access: yes, 2013
A numerically reliable state space algorithm is proposed for computing inner-outer factorizations of causal periodic descriptor systems. The main computational ingredients are the computation of a special condensed Kronecker-like form of periodic ...

Solution of Positive Periodic Discrete Lyapunov Equations with Applications to the Balancing of Periodic Systems. [PDF]

open access: yes, 1997
The discrete-time positive periodic Lyapunov equations have important applications in the balancing and potentially also in the model reduction of discrete-time periodic systems.

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Growth modeling in diameter and height at individual tree level for seasonal semi-deciduous forest

open access: yesBrazilian Journal of Biology
The objective of this study was to evaluate and compare two methodologies for estimating diameter at breast height (dbh) and total height at the individual tree level over time: (i) direct projection of future tree diameter and height (dbh2 and Ht2) and (
