Cover Story: Some boron compounds are atropisomers, which may have different properties according to their rotation. Axial chirality has been found in certain borazines, azaborines, NHC-boranes, aminoarylboranes, and even nonbiaryl compounds doped with boron. Since many boron compounds have interesting pharmaceutical, optical, and electronic properties, the methods to isolate their rotamers, or even to produce them pure by asymmetric synthesis, have become an important research target.

Virtual Coordinate System Based on a Circulant Topology for Routing in Networks-On-Chip

  • Andrei M. Sukhov,
  • Aleksandr Y. Romanov and
  • Maksim P. Selin

21 January 2024

In this work, the circulant topology as an alternative to 2D mesh in networks-on-chip is considered. A virtual coordinate system for numbering nodes in the circulant topology is proposed, and the principle of greedy promotion is formulated. The rules...

Detecting Phase Transitions through Non-Equilibrium Work Fluctuations

  • Matteo Colangeli,
  • Antonio Di Francesco and
  • Lamberto Rondoni

20 January 2024

We show how averages of exponential functions of path-dependent quantities, such as those of Work Fluctuation Theorems, detect phase transitions in deterministic and stochastic systems. State space truncation—the restriction of the observations...

Optimizing Connectivity and Coverage for Millimeter-Wave-Based Networks

  • Pablo Adasme,
  • Ali Dehghan Firoozabadi and
  • Sergio Cordero

19 January 2024

In this article, the problem of achieving the minimum backbone connectivity cost while simultaneously maximizing user coverage for 5G millimeter-wave (mmWave)-based networks is considered. Let G=(N,E) be an input graph instance with a set of nodes N...
