Primary field experiences: Critical for primary generalist physical education teachers? [PDF]
Generalist primary teachers teach physical education in many countries, and their preparation has been the subject of attention internationally. While they undertake field experiences as part of their preparation to teach, it is unclear how much of their teaching is focused on physical education.

Free Field Realizations of 2D Current Algebras, Screening Currents and Primary Fields [PDF]
In this paper we consider Wakimoto free field realizations of simple affine Lie algebras, a subject already much studied. We present three new sets of results. (i) Based on quantizing differential operator realizations of the corresponding Lie algebras we provide general universal very simple expressions for all currents, more compact than has been ...

Mapping receptive fields in primary visual cortex
Nearly 40 years ago, in the pages of this journal, Hubel and Wiesel provided the first description of receptive fields in the primary visual cortex of higher mammals. They defined two classes of cortical cells, ‘simple’ and ‘complex’, based on neural responses to simple visual stimuli.

Primary fields in celestial CFT [PDF]
Abstract The basic ingredient of CCFT holography is to regard four-dimensional amplitudes describing conformal wave packets as two-dimensional conformal correlation functions of the operators associated to external particles. By construction, these operators transform as quasi-primary fields under SL(2, ℂ) conformal symmetry group ...

Primary singularities of vector fields on surfaces [PDF]
Unless another thing is stated one works in the $C^\infty$ category and manifolds have empty boundary. Let $X$ and $Y$ be vector fields on a manifold $M$. We say that $Y$ tracks $X$ if $[Y,X]=fX$ for some continuous function $f\colon M\rightarrow\mathbb R$.
