Phosphoglycerate mutase catalyzes the interconversion between 2-phosphoglycerate and 3-phosphoglycerate in the glycolytic and gluconeogenic pathways. They exist in two unrelated forms, that is either cofactor (2,3-diphosphoglycerate) dependent or cofactor-independent. These two enzymes have no similarity in amino acid…

We provide extended evidence that mode-coupling theory (MCT) of supercooled liquids for the F(12) schematic model admits a microscopic realization based on facilitated spin models with tunable facilitation. Depending on the facilitation strength, one observes two distinct dynamical glass transition lines--continuous a…

The phase behavior of the water confined between hydrophobic pillars was studied by using a simple thermodynamic theory and the lattice gas Monte Carlo simulation. The drying transition of water with decreasing spacing between pillars is related to the Wenzel (WZ) to Cassie–Baxter (CB) transition of droplet. Our theor…

The adiabatic temperature change (ΔT) during the magnetization and demagnetization processes of bulk gadolinium is directly measured for several applied magnetic fields in the temperature range 285 K to 305 K. During the magnetization process, ΔT measurements display the same maximum for each applied field when plotte…
