A study on congruency effects and numerical distance in fraction comparison by expert undergraduate students
(Frontiers Media, 2020)
School mathematics comprises a diversity of concepts whose cognitive complexity is still poorly understood, a chief example being fractions. These are typically taught in middle school, but many students fail to master ...
Ground state solution for differential equations with left and right fractional derivatives
(Wiley & Sons, 2015)
In this work, we study the existence of positive solutions for a class of fractional differential equation given by
D-t(infinity-infinity)alpha D(t)(alpha)u(t) + u(t) = f(t,u(t)),
u is an element of H-alpha (R), ...
Middle Schoolers’ Biases and Strategies in a Fraction Comparison Task
(Springer Netherlands, 2019)
© 2018, Ministry of Science and Technology, Taiwan.The present study uses a short, computerized task to investigate individual differences among middle school students in terms of the intuitions and strategies that they ...
Semilinear fractional differential equations: global solutions, critical nonlinearities and comparison results
(Juliusz Schauder Center for Nonlinear StudiesTorun, 2015)
In this work we study several questions concerning to abstract fractional Cauchy problems of order 'alfa' 'PERTENCE A' (0; 1). Concretely, we analyze the existence of local mild solutions for the problem, and its possible ...

Monodisperse lignin fractions as standards in size-exclusion analysis Comparison with polystyrene standards
(ELSEVIER SCIENCE BV, 2009)
The difficulty of preparing monodisperse lignin fractions on a large scale is a limiting factor in many applications. The present paper addresses this problem by examining the properties and size-exclusion behavior of ...
Harvest Management Problem with a Fractional Logistic Equation
(Akadémiai Kiadó, 2021-10)
In this article, we study a fractional control problem that models the maximization of the profit obtained by exploiting a certain resource whose dynamics are governed by the fractional logistic equation. Due to the ...
Fractional convexity
(Springer, 2021-08-17)
We introduce a notion of fractional convexity that extends naturally the usual notion of convexity in the Euclidean space to a fractional setting. With this notion of fractional convexity, we study the fractional convex ...
Anticomplementary activity of equine whole IgG antivenoms: comparison of three fractionation protocols
(2005-01)
Early adverse reactions occur in a number of patients treated with heterologous antivenoms and have been associated with anticomplementary activity (ACA). In order to reduce the ACA of equine whole IgG antivenoms produced ...
