Thermodynamic modeling of the CaO-SiO2-CaCO3-H2O closed and open system at 25ºC
Materiales de Construccion, 2003 This paper reports on a thermodynamic calculation-based study of the CaO-SiO2-CaCO3-H2O closed system at 25 °C, conducted to determine the range of carbonate ion concentrations at which each phase of the system is stable. Portlandite (CH) and the CSH gel

The thermodynamic model for nuclear multifragmentation [PDF]
Physics Reports, 2005 A great many observables seen in intermediate energy heavy ion collisions can be explained on the basis of statistical equilibrium. Calculations based on statistical equilibrium can be implemented in microcanonical ensemble (energy and number of particles in the system are kept fixed), canonical ensemble (temperature and number of particles are kept ...

Thermodynamics of the Schwinger and Thirring models [PDF]
Physical Review D, 1987 The thermodynamical partition functions for both the Schwinger and Thirring models are evaluated. The imaginary time formalism of quantum field theory at finite temperature and pathintegral methods are used. For the Schwinger model, the partition function displays two features: (i) no physical (transverse) photons exist in 1+1 dimensions; (ii) the ...

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

FEBS Open Bio, EarlyView.Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Directed evolution of enzymes at the crossroads of tradition and innovation
FEBS Open Bio, EarlyView.An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.
