On social sensitivity to either zealot or independent minorities
This article uses the self-organized temporal criticality (SOTC) model to identify the timing of crucial events as a new mechanism with which to generate criticality, thereby establishing a way for the internal dynamics of the decision making process to suppresss the sensitivity of social opinion to either zealot or independent minorities.

Building a Team for EXtragalactic AStrophysics (TEXAS) in the Dallas-Fort Worth Metroplex
Data management plan for the grant, "Building a Team for EXtragalactic AStrophysics (TEXAS) in the Dallas-Fort Worth Metroplex". The project will build a new partnership between the University of North Texas (UNT), an R1 Minority-Serving Institution (MSI)/ Hispanic-Serving Institution (HSI), and the University of Texas at Dallas (UTD). During the pilot phase, the team will establish a post-baccalaureate bridge program and organize monthly colloquia and annual symposia to broaden the participation of underrepresented groups in astronomy.

Relaxation time approximations in PAOFLOW 2.0
Article presents the implementation of relaxation time approximation models in the calculation of Boltzmann transport in PAOFLOW 2.0 and applies those to model band-structures. In addition, using a self-consistent fitting of the model parameters to experimental conductivity data, the authors provide a flexible tool to extract scattering rates with high accuracy. They illustrate the approximations using simple models and then apply the method to GaAs, Si, Mg₃Sb₂, and CoSb₃.

Magnetic plasma expulsion
The article presents one scheme for what is referred to as magnetic plasma expulsion, which would prevent the plasma from entering a given region. Magnetic plasma expulsion techniques may allow instrumentation access to the interiors of plasmas. Magnetic plasma expulsion techniques may also make alternative approaches for magnetic plasma confinement possible. Particle-in-cell simulation with the Warp code is used to study magnetic plasma expulsion. Some conditions for achieving magnetic plasma expulsion are reported.

Computational Topology Techniques Help To Solve A Long-Lasting Forensic Dilemma: Aldo Moro's Death
The article shows how a recently-introduced method from algebraic topology, namely proximal planar vortex 1-cycles, might be helpful in detecting hidden features of the shapes and holes in images, therefore contributing to the solution of both cold and fresh forensic cases. They apply this technique in a recent case, Aldo Moro's death.

High-Throughput Computational Search for Half-Metallic Oxides
The article describes a high-throughput computational search for half-metallic compounds. The analysis of calculated electronic properties of thousands of materials from the inorganic crystal structure database allowed the authors to identify potential half metals. They found over two-hundred strong half-metallic oxides; several of them have never been reported before.

Topologically driven linear magnetoresistance in helimagnetic FeP
Article presenting a series of high magnetic field experiments on high-quality single crystals of FeP. The study shows that resistance not only increases without saturation by up to several hundred times its zero-field value by 35 T, but that it also exhibits an anomalously linear field dependence over the entire range when the field is aligned precisely along the crystallographic c-axis.
