Suppressing selection for antibiotic resistance in the environment: A transparent, ecology-based approach to predicted no-effect concentrations Open
Selection for antibiotic resistance has been demonstrated at low, environmentally-relevant antibiotic concentrations. Over the past decade, the concept of minimum selective concentrations (MSC) has been adopted in environmental regulation …

Conformal Surface Splines Open
We introduce a family of boundary conditions and point constraints for conformal immersions that increase the controllability of surfaces defined as minimizers of conformal variational problems. Our free boundary conditions fix the metric …

N fertilization strategies for the use of P-rich organic amendments in the restoration of soil productivity—short-term responses in two soils Open
To facilitate nutrient management and the use of manure as a feedstock for biogas production, manure is often separated into a solid and a liquid fraction. The former fraction is usually high in P and low in N, so when incorporated in the …

Rolling spheres and the Willmore energy Open
The Willmore energy plays a central role in the conformal geometry of surfaces in the conformal 3-sphere \(S^3\). It also arises as the leading term in variational problems ranging from black holes, to elasticity, and cell biology. In the …

Plasma knots Open
We present a Lagrangian method for the computation of ideal plasma knots and links. It is based on a variational principle for stable equilibria of an ideal plasma in the case of a free boundary subjected to external magnetic or plasma pre…

Constrained willmore surfaces Open
Smooth curves and surfaces can be characterized as minimizers of squared curvature bending energies subject to constraints. In the univariate case with an isometry (length) constraint this leads to classic non-linear splines. For surfaces,…

The International Political Thought of Johann Jacob Schmauss and Johann Gottlieb Heineccius: Natural Law, Interest, History and the Balance of Power Open
This chapter explores the international political thought of Johann Jacob Schmauss (1690–1757) and Johann Gottlieb Heineccius (1681–1741). Their writings are discussed in the wider context of the natural law tradition (in particular in vie…

Introduction Open
The devastating fire in the 200-year-old Museu Nacional in Rio de Janeiro on September 2, 2018, demonstrates the vital importance of the historiography of sciences and the arts. As most collections have vanished, it is left to the history …

“Three Long Rows of Empty Shelves” to Fill Open
In 1928-29 and 1930, the German-Brazilian anthropologist Curt Nimuendajú was contracted twice by German ethnological institutions (above all, museums) for organizing ethnographic collections and carrying out anthropological research among …

Finding Conformal and Isometric Immersions of Surfaces Open
We introduce a family of variational functionals for spinor fields on a compact Riemann surface $M$ that can be used to find close-to-conformal immersions of $M$ into $\mathbb{R}^3$ in a prescribed regular homotopy class. Numerical experim…

Trust in Early Modern International Political Thought, 1598–1713 Open
Can there ever be trust between states? This study explores the concept of trust across different and sometimes antagonistic genres of international political thought during the seventeenth century. The natural law and reason of state trad…

Methodological flaws introduce strong bias into molecular analysis of microbial populations Open
The identified weaknesses of commonly used methods to study microbial diversity can be overcome by a multi-level approach, which produces more reliable data about the fate and behaviour of microbial communities of engineered habitats such …

Partnership for Edge Physics Simulation (EPSI) Open
We propose to develop advanced simulation codes, based upon an extreme parallelism, first principles kinetic approach, to address the challenges associated with the edge region of magnetically confined plasmas. This work is relevant to bot…
