For various lattice gas models with nearest neighbour exclusion (and, in one case, second-nearest neighbour exclusion as well), we obtain lower bounds on m, the average number of particles on the non-excluded lattice sites closest ∗We dedicate this work to the memory of Ann Stell, beloved friend of OP and beloved wife of GS.

Lectins (carbohydrate-binding proteins) are able to distinguish different patterns of glycosylation on cell surfaces. This study investigated the effects lectins from Alpinia purpurata inflorescence (ApuL) and Schinus terebinthifolia leaf (SteLL) viability human leukemia cells (K562, chronic myeloid leukemia; JURKAT, acute lymphoblastic leukemia) mesenchymal stem (MSCs) umbilical cords. In addi...

We study the liquid anomalies arising from the Stell-Hemmer interaction, using molecular dynamics simulations and approximate 2D solutions. We observe in the liquid phase three types of anomalies: (i) An increase in specific volume upon cooling, (ii) an increase in isothermal compressibility upon cooling, and (iii) an increase in the diffusion coefficient with pressure. We relate the anomalies ...
