Cover Story: Gear shifting is best known from car driving. On a flat highway, the highest gear gives the highest speed. When driving uphill, shifting to a lower gear may increase the speed and prevent stalling; the optimal gear number decreases with the increasing slope of the hill. Can living organisms shift gears? The answer is yes. Cells can engage in alternative pathways that enable them to continue making energy molecules (‘ATP’) when these contain more Gibbs energy, even though this uses more nutrient energy per energy molecule. The continued synthesis of the energy molecules enables the cells to utilize these for growth and survival when faced with thermodynamic challenges. View this paper

Friction and Stiffness Dependent Dynamics of Accumulation Landslides with Delayed Failure

  • Srđan Kostić,
  • Kristina Todorović,
  • Žarko Lazarević and
  • Dragan Prekrat

24 July 2023

We propose a new model for landslide dynamics under the assumption of a delay failure mechanism. Delay failure is simulated as a delayed interaction between adjacent blocks, which mimics the relationship between the accumulation and feeder part of th...

Kinetic Models of Wealth Distribution with Extreme Inequality: Numerical Study of Their Stability against Random Exchanges

  • Asim Ghosh,
  • Suchismita Banerjee,
  • Sanchari Goswami,
  • Manipushpak Mitra and
  • Bikas K. Chakrabarti

24 July 2023

In view of some recent reports on global wealth inequality, where a small number (often a handful) of people own more wealth than 50% of the world’s population, we explored if kinetic exchange models of markets could ever capture features where...

Kernel-Free Quadratic Surface Regression for Multi-Class Classification

  • Changlin Wang,
  • Zhixia Yang,
  • Junyou Ye and
  • Xue Yang

24 July 2023

For multi-class classification problems, a new kernel-free nonlinear classifier is presented, called the hard quadratic surface least squares regression (HQSLSR). It combines the benefits of the least squares loss function and quadratic kernel-free t...
