Properties of binary systems in a one-dimensional approximation
<p>We present numerically obtained tables of properties of stars in a binary system as a function of the effective potential: volume-equivalent radii of the equipotential surfaces, effective accelerations averaged over the same equipotential surfaces and the properties of the L<sub>1</sub> plane cross-sections. The tables are obtained for binaries where the ratios of the primary star mass to the companion star mass are from 10<sup>-6</sup> to 10<sup>5</sup> and include equipotential surfaces up to the star's outer Lagrangian point. We supply a sample code showing how to use our tables to get the average effective accelerations in one-dimensional stellar codes.</p> <p>Updates will be available at <a href="https://github.com/AliPourmand/1D_binary_star_properties">https://github.com/AliPourmand/1D_binary_star_properties</a>.

Site-directed placement of three-dimensional DNA origami
<p><span>The combination of lithographic methods with 2D DNA origami self-assembly has led, among others, to the development of photonic crystal cavity arrays and the exploration of sensing nanoarrays where molecular devices are patterned on the sub-micron scale. Here we extend this concept to the third dimension by mounting 3D DNA origami onto nano-patterned substrates, followed by silicification to provide mechanical and chemical stability. We created fully addressable, three-dimensional nanopatterns of hybrid DNA-silica structures with heights up to 50 nm and feature size in the sub-10-nm regime. Our versatile and scalable method relying on self-assembly at ambient temperatures offers the potential to 3D-position any inorganic and organic components compatible with DNA origami nanoarchitecture, demonstrated with gold nanoparticles. This way of nanotexturing could provide a route for the low-cost production of complex and 3D-patterned surfaces and integrated devices designed on the molecular level while reaching macroscopic dimensions.</span></p>
Simulation of the Moving Boundary during Freezing of a One-Dimensional Food Slab
<p>To calculate the moving boundary (MB) of a finite 1D moist food slab, which is cooled by convection at the exposed surface, a finite difference model was employed, invoking the Stefan condition. The primary objective of this project was to generate synthetic data comprising MB position-time pairs. The MB time profiles were generated using a nearly orthogonal array, which accounts for the effects of the Biot number, dimensionless cooling-medium temperature, dimensionless latent heat, and thermal conductivity parameter. The last two parameters play a crucial role in controlling the temperature dependence of the effective heat capacity and thermal conductivity of the food material. The generated data will be utilized to develop statistical models of the MB, effectively accounting for the influence of temperature-dependent thermal properties</p>
Plasmoid identification and statistics in two-dimensional Harris sheet and GRMHD simulations
<p>Animations accompanying a scientific paper with the following title; <strong>Plasmoid identification and statistics in two-dimensional Harris sheet and GRMHD simulations</strong>, by authors J.T. Vos, H. Olivares, B. Cerutti, and M.A. Mościbrodzka.</p> <p>The filename denotes to which figure the animation corresponds.</p> <p><strong>Abstract:</strong><br> Magnetic reconnection is a ubiquitous phenomenon for magnetized plasma and leads to the rapid reconfiguration of magnetic field lines. During reconnection events, plasma is heated and accelerated until the magnetic field lines enclose and capture the plasma within a circular configuration. These plasmoids could therefore observationally manifest themselves as hot spots that are associated with flaring behaviour in supermassive black hole systems, such as Sagittarius A*. We have developed a novel algorithm for identifying plasmoid structures, which incorporates watershed and custom closed contouring steps. From the identified plasmoids, we determine the plasma characteristics and energetics in magnetohydrodynamical simulations. The algorithm’s performance is showcased for a high-resolution suite of axisymmetric ideal and resistive magnetohydrodynamical simulations of turbulent accretion discs surrounding a supermassive black hole. For validation purposes, we also evaluate several Harris current sheets that are well-investigated in the literature. Interestingly, we recover the characteristic power-law distribution of plasmoid sizes for both the black hole and Harris sheet simulations. This indicates that while the dynamics are vastly different, with different dominant plasma instabilities, the plasmoid creation behaviour is similar. Plasmoid occurrence rates for resistive general relativistic magnetohydrodynamical simulations are significantly higher than for their ideal counterpart. Moreover, the largest identified plasmoids are consistent with sizes typically assumed for semi-analytical interpretation of observations. We recover a positive correlation between the plasmoid formation rate and a decrease in black-hole-horizon-penetrating magnetic flux. These results demonstrate the efficacy of the newly developed algorithm which has enabled an extensive quantitative analysis of plasmoid formation for black hole accretion simulations.</p>
