Approximate Arithmetic Training Improves Informal Math Performance in Low Achieving Preschoolers
Frontiers in Psychology, 2018 Recent studies suggest that practice with approximate and non-symbolic arithmetic problems improves the math performance of adults, school aged children, and preschoolers. However, the relative effectiveness of approximate arithmetic training compared to

Inequalities for multiplicative arithmetic functions [PDF]
arXiv, 2011 We study arithmetic inequalities for multiplicative, sub(super)-multiplicative, sub(super)-homogeneous functions. Applications for the classical arithmetic functions are pointed out.

Optoelectronic Devices for In‐Sensor Computing
Advanced Materials, EarlyView.The raw data obtained directly from sensors in the noisy analogue domain is often unstructured, which lacks a predefined format or organization and does not conform to a specific data model. Optoelectronic devices for in‐sensor visual processing can integrate perception, memory, and processing functions in the same physical units, which can compress ...

Advanced Materials, EarlyView.Organic photodiodes (OPDs) with low dark current and stable detectivity under light irradiation, air exposure, and heating are realized using a nanoparticle‐based Zn‐chelated PEIE (PEI‐Zn NP) electron transport layer. This formulation effectively suppresses photocurrent degradation and dark current increase, ensuring enhanced environmental stability ...

Occurence of contradictions in Zermelo-Fraenkel theory under extension of base language by recursion functions [PDF]
Компьютерные исследования и моделирование, 2009 It is shown that the extension of base language in Zermelo-Fraenkel theory, which allows a relations on recursion function of natural argument, may lead in Set Theory to contradictive constructions on arithmetic level.

Using QCM‐D for Real‐Time Analysis of Cell Adhesion Dynamics at Biointerfaces
Advanced Materials Interfaces, EarlyView.This study explores adhesion of human fibroblasts to functionalized biomaterial surfaces. Quartz crystal microbalance with dissipation (QCM‐D) is used to measure cell responses in real time. The QCM‐D signalis correlated with changes in cell morphology and focal adhesion kinase (FAK) activation. This data shows a positive correlation between the energy

Advanced Materials Interfaces, EarlyView.This work presents a systematic characterization of an emerging polymer platform, off‐stoichiometry thiol‐ene, in terms of its ability to support the formation, growth, and metabolic activity of Staphylococcus aureus biofilms. The findings indicate that thiol‐enes promote S.

Adelic divisors on arithmetic varieties [PDF]
arXiv, 2013 In this article, we generalize several fundamental results for arithmetic divisors, such as the continuity of the volume function, the generalized Hodge index theorem, Fujita's approximation theorem for arithmetic divisors and Zariski decompositions for arithmetic divisors on arithmetic surfaces, to the case of the adelic arithmetic divisors.
