Nouvelle économie du développement et essais cliniques randomisés : une mise en perspective d’un outil de preuve et de gouvernement by Agnès Labrousse

“…It is an instrument of proof but also a trendy instrument of government – in the Foucaldian sense. Its manifold applications remind of other forms of social engineering and belong to a type of governmentality noticeably distinct from the neoliberal tradition.…”

Transition from the topological to the chaotic in the nonlinear Su–Schrieffer–Heeger model by Kazuki Sone, Motohiko Ezawa, Zongping Gong, Taro Sawada, Nobuyuki Yoshioka, Takahiro Sagawa

“…We also propose the correspondence between the absolute value of the topological invariant and the dimension of the stable manifold under sufficiently weak nonlinearity. Our results provide a general guiding principle to investigate the nonlinear bulk–edge correspondence that can potentially be extended to arbitrary dimensions.…”

Graphing, homotopy groups of spheres, and spaces of long links and knots by Robin Koytcheff

“…We show that, up to knotting, these account for all the homotopy groups in a range which depends on the dimensions of the source manifolds and target manifold and which roughly generalizes the triple-point-free range for isotopy classes. …”

Convergence Rates of Gradient Methods for Convex Optimization in the Space of Measures by Chizat, Lénaïc

“…We study the convergence rate of Bregman gradient methods for convex optimization in the space of measures on a $d$-dimensional manifold. Under basic regularity assumptions, we show that the suboptimality gap at iteration $k$ is in $O(\log (k)k^{-1})$ for multiplicative updates, while it is in $O(k^{-q/(d+q)})$ for additive updates for some $q\in \lbrace 1,2,4\rbrace $ determined by the structure of the objective function. …”

From applied ethics to innovation practice: an ethics-by-design approach for constructive consideration of ELSI in technological design decisions by Jan Mehlich, Christiane Woopen

“…The manifold ethical, legal, and societal implications (ELSI) of new and emerging technologies are often elicited and dealt with too late in the innovation process which creates severe challenges and risks for regulators, appliers, and users as well as society as a whole. …”

Anthropological Perspective on the Decision-Making Process in Environmental Protection by Grzegorz Embros

“…Against this backdrop, the paper draws on selected patterns, which constitute a point of reference in the formulation of the decision-making process, namely, the Deming Cycle, and the control system worked out by Marian Mazur. Among the manifold determinants of the decision-making process, special emphasis is put on the anthropological one, with reference to the approach proposed by Michał Gierycz. …”
