A Note on the Existence and Optimal Control of Atangana–Baleanu Fractional Stochastic Integrodifferential System With Noninstantaneous Impulses

Optimal Control Applications and Methods, EarlyView.
Optimal Control of AB Caputo Fractional Stochastic Integrodifferential Control System with Noninstantaneous Impulses. ABSTRACT This study is concerned with the existence of mild solution and optimal control for the Atangana–Baleanu fractional stochastic integrodifferential system with noninstantaneous impulses in Hilbert spaces. We verify the existence

Batch Heterogeneous Catalytic Selective Hydrogenation of Vegetable Oils Over Lindlar Catalyst: Kinetic Modeling Supported by Reaction Mechanisms

ChemistryOpen, EarlyView.
Heterogeneous catalytic selective hydrogenation of vegetable oils was modeled by Hougen–Watson approach to obtain kinetic rate laws. Parameters were obtained by nonlinear regressions on batch experimental data, and the best mechanism to interpret those experimental data was chosen on a statistical basis (higher coefficient of determination R2) and by ...

Unraveling the Link Between n‐Back Working Memory and Algebraic Ability in Adolescents: Correlations and Training Effects

PsyCh Journal, EarlyView.
ABSTRACT Individuals with higher working memory capacities excel in mathematics performance. However, limited research has explored the impact of working memory on adolescents' algebraic ability and the transferability of training effects. Therefore, we conducted the current investigation with Chinese adolescents. In a correlational study (n = 218), we

Numerical Simulation of Three‐Dimensional Unsteady Extrudate Swell Through Annular Dies: Effects of Die Core Opening Position and Sag on Parison Formation

Polymer Engineering &Science, EarlyView.
Study on transient parison formation at various strokes during extrusion of Newtonian and viscoelastic fluids. In the presence of an offset between the mandrel and the bushing, Newtonian fluids exhibit a reduction in extrudate diameter, whereas viscoelastic fluids display diameter swelling only at flow rates exceeding a critical threshold.

Exploration of the Predictive Validity of Middle School Math Screeners

Psychology in the Schools, EarlyView.
ABSTRACT Universal screening is a key element of multi‐tiered systems of support. Relative to literacy, fewer studies have investigated the psychometric properties of math assessments particularly amongst middle school students. We investigated whether outcomes from two types of curriculum‐based measures (CBMs), computational fluency (M‐COMP) and ...

A Comparison of the Validity of Growth Estimates From Early Math Curriculum Based Measures and a Computer Adaptive Test

Psychology in the Schools, EarlyView.
ABSTRACT This study compared the extent to which growth on two types of early math assessments (curriculum‐based measures [CBMs] and computer adaptive tests) predicted end of year performance in broad math skills as well as improvement in broad math skills in Kindergarten (n = 211) and Grade 1 (n = 79) students.

Recursive Relations for the S‐matrix of Liouville Theory

Fortschritte der Physik, EarlyView.
Abstract The relation between the vertex operators of the in and out fields in Liouville theory is analyzed. This is used to derive equations for the S‐matrix, from which a recursive relation for the normal symbol of the S‐matrix for discrete center‐of‐mass momenta is obtained.
