Pensamento e linguagem: uma discussão no campo da psicologia da educação matemática Thought and language: a discussion in the field of psychology of mathematics eucation

Psicologia: Reflexão e Crítica, 2005
O presente artigo retoma a discussão acerca da relação entre pensamento e linguagem no processo de conceptualização em matemática. Nesse sentido, são oferecidos subsídios empíricos a partir de outros estudos, que permitem discutir e contestar a idéia ...

Development of algebraic expressions e-modules through realistic mathematics education approach

Infinity
Students often struggle with algebraic expressions due to the abstract nature of mathematical symbols. The Realistic Mathematics Education (RME) approach offers an alternative to help students solve these problems.

Morse homology for the heat flow

, 2010
We use the heat flow on the loop space of a closed Riemannian manifold to construct an algebraic chain complex. The chain groups are generated by perturbed closed geodesics.

A Perspective on Interactive Theorem Provers in Physics

Advanced Science, EarlyView.
Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Investigation of the Effect of Virtual Manipulatives Usage on the Process of Eliminating Misconceptions about Algebraic Expressions and Equations

International Journal of Turkish Education Sciences
In this study, the effect of activity-based mathematics content enriched with virtual manipulatives on the process of eliminating misconceptions about algebraic expressions and equations was examined.

Selective Targeting of Immune Checkpoints HLA‐G and CD47 Using Novel Dual Signaling Protein DSP216 Promotes Innate Anticancer Immunity

Advanced Science, EarlyView.
The inhibitory immune checkpoints HLA‐G and CD47 are expressed on certain tumor types and inhibit immune cells in the tumor microenvironment. DSP216 binds specifically to cancer cells expressing both HLA‐G and CD47, and blocks their inhibitory signaling.

Difference subgroups of commutative algebraic groups over finite fields

, 1998
The work of Chatzidakis and Hrushovski on the model theory of difference fields in characteristic zero showed that groups defined by difference equations have a very restricted structure. Recent work of Chatzidakis, Hrushovski and Peterzil [CHP] extends the class of difference fields for which this sort of result is known to positive characteristic. In

Mechanoadaptation via Myosin Cytoplasmic Redistribution Protects Circulating Tumor Cells From Shear‐induced Death During Hematogenous Dissemination

Advanced Science, EarlyView.
This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

Distinct Biotypes of Visual Perception in Major Depressive Disorder

Advanced Science, EarlyView.
In a discover dataset (272 acute MDD patients), this work identifies a novel depression biotype characterized by impaired visual motion perception, using machine learning clustering. An independent dataset confirms the robustness of this biotype through cross‐validation and demonstrates its generalizability.
