March 2025

Transdisciplinary Science Group, Cawthron Institute, Nelson, New Zealand.

Agriculture and food systems are major sources of plastic pollution but they are also vulnerable to their diverse lifecycle impacts. However, this problem is not well-recognized in global policy and scientific discourse, agendas, and monitoring of food systems. The United Nations-led Global Plastics Treaty, which has been under negotiation since 2022, is a critical opportunity to address pollution across the entire plastics lifecycle for more sustainable and resilient food systems.

Two Fe(III)Mn(III) bimetallic compounds, [Tp*Fe (CN)][(Mnsalen)]·MeOH·MeCN () and [Tp*Fe (CN)][Mnsalphen]·MeOH·HO (), were prepared by assembling the tricyanometalate building block (TEA)N [Tp*Fe(CN)] [Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate] and the respective Mn Schiff base precursors [salen = ,'-ethylenebis(salicylideneiminate), salphen = ,-bis(salicylidene)-1,2-phenylenediamine]. Both compounds exhibit a one-dimensional (1D) zigzag chain structure linked by cyanide bridges, forming a (-Fe-C≡N-Mn-N≡C-) motif. Magnetic studies show a gradual increase of χ values in both complexes upon lowering temperature, indicating ferromagnetic coupling between the Fe and Mn metal centers with Curie-Weiss constants of +1.

Higher Structure of Chiral Symmetry.

Commun Math Phys

March 2025

Center for Cosmology and Particle Physics, New York University, New York, USA.

A recent development in our understanding of the theory of quantum fields is the fact that familiar gauge theories in spacetime dimensions greater than two can have non-invertible symmetries generated by topological defects. The hallmark of these non-invertible symmetries is that the fusion rule deviates from the usual group-like structure, and in particular the fusion coefficients take values in topological field theories (TFTs) rather than in mere numbers. In this paper we begin an exploration of the associativity structure of non-invertible symmetries in higher dimensions.

Ultra-low frequency waves, with periods between 1-1000 s, are ubiquitous in the near-Earth plasma environment and play an important role in magnetospheric dynamics and in the transfer of electromagnetic energy from the solar wind to the magnetosphere. A class of those waves, often referred to as Pc3 waves when they are recorded from the ground, with periods between 10 and 45 s, are routinely observed in the dayside magnetosphere. They originate from the ion foreshock, a region of geospace extending upstream of the quasi-parallel portion of Earth's bow shock.

Objectives: To describe and assess, via simulation, a constraint-based spline approach to implement smooth hazard ratio (HR) waning in time-to-event analyses.

Methods: A common consideration when extrapolating survival functions to evaluate the long-term performance of a novel intervention is scenarios where the beneficial effect of an intervention eventually disappears (treatment effect waning). One approach to relaxing the proportional hazards assumption for a treatment effect is to model it as a function of the timescale, with a spline function offering a flexible approach.
