Ecography, EarlyView.Phytoplankton communities affect carbon dynamics worldwide, strongly influencing the quality and quantity of organic carbon in coastal ecosystems. Yet, we still know little about the impacts of changing phytoplankton community composition on the potential carbon pathways in estuaries and coasts.

European Eating Disorders Review, EarlyView.ABSTRACT Objective Persons with bulimia nervosa (BN) often gain weight during treatment, which potentially poses a threat to treatment adherence. Although weight suppression has been found to be a predictor of weight gain in persons with BN, research about the trajectory of weight changes during treatment and other predictors thereof is scarce.

Funzioni caratteristiche e polinomi s-ortogonali [PDF]
Rendiconti di Matematica e delle Sue Applicazioni, 1994 Two remarkable systems of s-orthogonal polynomials and their connected hyper-Gaussian quadrature formulae are considered. By method of “characteristic function” (in the complex plane), asymptotic properties for approximate estimations of integrals are ...

On the associated orthogonal polynomials
Journal of Computational and Applied Mathematics, 1990 AbstractBy using the second-order recurrence relation this paper gives some new results on associated orthogonal polynomials without referring to the continued fractions' tool. Some results are very useful for obtaining the second-order differential equation satisfied by the semi-classical orthogonal polynomials (Hendriksen and van Rossum (1985 ...

Food Frontiers, EarlyView.ABSTRACT Osmanthus fragrans extract (OFE) has significant potential for application in the beverage and cosmetic industries. However, the conventional extraction processes of OFE are affected by multiple factors, making it challenging to identify parameters that can be synergistically optimized for diverse qualities.

Stock Return Prediction Based on a Functional Capital Asset Pricing Model
Journal of Forecasting, EarlyView.ABSTRACT The capital asset pricing model (CAPM) is readily used to capture a linear relationship between the daily returns of an asset and a market index. We extend this model to an intraday high‐frequency setting by proposing a functional CAPM estimation approach.

Korobov’s controllability function method via orthogonal polynomials on [0,∞)
Visnik Harkivsʹkogo Nacionalʹnogo Universitetu im. V.N. Karazina. Cepiâ Matematika, Prikladna Matematika i MehanikaGiven a controllable system described by ordinary or partial differential equations and an initial state, the problem of finding a set of bounded positional controls that transfer the initial state to another state, not necessarily an equilibrium point ...
