Recurrent Inequalities and Some of their Applications to Picard and Mann Iterations
Annals of the West University of Timisoara: Mathematics and Computer Science, 2014 Two lemmas concerning the superior bound of a numerical sequence satisfying a common recurrence inequality are given. As applications, the error estimations are obtained for the Picard and Mann iterations in the case of demicontractive mappings ...

A Distributed Procedure for Computing Stochastic Expansions with Mathematica [PDF]
, 2010 The solution of a (stochastic) differential equation can be locally approximated by a (stochastic) expansion. If the vector field of the differential equation is a polynomial, the corresponding expansion is a linear combination of iterated integrals of ...

Raman Spectroscopy–Based Glucose Feed Control Automates Malic Acid Fermentation
Biotechnology and Bioengineering, EarlyView.Raman spectroscopy enables automated, closed‐loop glucose feeding for malic acid production with Ustilago trichophora. Online PLS regression of glucose and malic acid provides input for PID control to maintain 20 g/L glucose. The feed is dynamically adjusted and stopped in response to metabolic demand and product inhibition, demonstrating practical ...

, 2015 We study the impact of possible spiral-arm distributions of Galactic cosmic-ray sources on the flux of various cosmic-ray nuclei throughout our Galaxy. We investigate model cosmic-ray spectra at the nominal position of the sun and at different positions ...

Biological Reviews, EarlyView.ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Power bounded prolongations and Picard-Lindel�f iteration
Numerische Mathematik, 1990 The author continues several earlier studies of Picard-Lindelöf iteration of linear constant coefficient systems \(\dot x+Ax=f(t),\) \(x(0)=x_ 0\), where the matrix A is assumed to be split as \(A=M-N\) for iteration \(\dot x^ n+Mx^ n=Nx^{n-1}+f(t),\) \(x^ n(0)=x_ 0\) [see e.g. the author, ibid. 57, No.2, 147-156 (1990; Zbl 0697.65058)].

Business Strategy and the Environment, EarlyView.ABSTRACT Sustainability reports (SRs) are widely criticized for vague disclosures and selective emphasis on positive outcomes, yet systematic research on two core SR challenges remains limited: materiality (whether disclosed content is relevant) and balance (whether both achievements and challenges are reported).
