    • Described is a technique to exhaustively enumerate the thermodynamic properties of the water molecules solvating the active site of a protein in its apostate and calculate the relative binding affinities of congeneric compounds that bind to this protein. The subject matter includes sampling the configurations of the solvating water in the active site; extracting the thermodynamic information about the solvating water from these configurations by clustering the observed water configurations into regions of high water occupancy (e.g., “hydration sites”), computing the average system interaction energies of water molecules occupying the various hydrations sites, computing excess entropies of water molecules occupying the hydration sites; constructing a 3 dimensional hydration thermodynamics map of the protein active site; and computing relative binding affinities of congeneric ligands based on the principle that tighter binding ligands can displace more entropically structured and energetically depleted hydration sites from the active site into the bulk fluid.

    • In accordance with the present invention, a phonation valve which is cooperatively connectable to a breathing tube connected to a patient's airway, includes a valve body having first and second ends through which gas passes into and out of the valve. The first end is connectable to the breathing tube for passage of gas between the breathing tube and the valve. A valve seat is located within the valve body between the first and second ends. A thin, flexible diaphragm is provided, which is seated against the valve seat when the patient exhales. The diaphragm has a comfort-improving structural feature which can be 1) a shape which is at least partly concave on a side of the diaphragm facing the seat, and/or 2) a web of substantially uniform thickness with a plurality of discrete areas of different thicknesses dispersed around the web, which are capable of damping resonance vibration of the diaphragm during breathing by the patient.
