Twenty five years after KLS: A celebration of non-equilibrium statistical mechanics
When Lenz proposed a simple model for phase transitions in magnetism, he
couldn't have imagined that the "Ising model" was to become a jewel in field of
equilibrium statistical mechanics. Its role spans the spectrum, from a good
pedagogical example to a universality class in critical phenomena. A quarter
century ago, Katz, Lebowitz and Spohn found a similar treasure. By introducing
a seemingly trivial modification to the Ising lattice gas, they took it into
the vast realms of non-equilibrium statistical mechanics. An abundant variety
of unexpected behavior emerged and caught many of us by surprise. We present a
brief review of some of the new insights garnered and some of the outstanding
puzzles, as well as speculate on the model's role in the future of
non-equilibrium statistical physics.Comment: 3 figures. Proceedings of 100th Statistical Mechanics Meeting,

Legal aspects of contraceptive implants
Key message points
- There has been litigation in relation to the three types of harm associated with contraceptive implants: non-insertion, deep insertion and nerve injury.
- Recommendations for safe clinical practice can be derived from analysis of legal cases and published case reports.
- Nerve injury has invariably been caused by clinicians without upper limb surgical skills attempting difficult removals.
- The launch of the updated single-rod implant (Nexplanon®) may hold the best possibility for harm reduction.
- Litigation in relation to side effects can lead to the withdrawal of safe and effective contraceptive products, so reducing choice for wome
