Prefreezing is the prewetting of the crystalline phase at the interface of a melt to a solid substrate via a first-order phase transition. We present a phenomenological theory of prefreezing and analyze thermodynamic properties of the prefrozen crystalline layer. The theory enables a clear thermodynamic explanation of the abrupt formation of a mesoscopically thick crystalline layer during cooling and defines the corresponding transition temperature as a function of the interfacial free energies. It is shown that the interfacial energy difference γ-( γ+ γ) acts as a driving force for prefreezing. The analytical results are congruent with recent experimental outcomes for poly(ε-caprolactone) crystallized on graphite via prefreezing. The calculated interfacial free energies take reasonable values being close to the experimental estimates.

The internally contracted multireference coupled-cluster (icMRCC) method is analyzed through third order in perturbation theory. Up to second order, the icMRCC perturbation expansion is equivalent to ...
We perform a nonperturbative study of the electroweak phase transition (EWPT) in the two Higgs doublet model (2HDM) by deriving a dimensionally reduced high-temperature effective theory for the model,...
We combine tools from effective field theory and generalized unitarity to construct a map between on-shell scattering amplitudes and the classical potential for interacting spinless particles. For gen...
Interpretative phenomenological analysis (IPA) is an approach to qualitative analysis that has increasingly been used in health and psychology over the past 10-15 years.

Case-control comparison of clinical population, interventional and single-center research.
An interdisciplinary study dealing with the transmission of messages or signals, or the communication of information. Information theory does not directly deal with meaning or content, but with physical representations that have meaning or content. It overlaps considerably with communication theory and CYBERNETICS.
A psychological theory based on dimensions or categories used by a given person in describing or explaining the personality and behavior of others or of himself. The basic idea is that different people will use consistently different categories. The theory was formulated in the fifties by George Kelly. Two tests devised by him are the role construct repertory test and the repertory grid test. (From Stuart Sutherland, The International Dictionary of Psychology, 1989)
The theory that the radiation and absorption of energy take place in definite quantities called quanta (E) which vary in size and are defined by the equation E=hv in which h is Planck's constant and v is the frequency of the radiation.
The theory that infectious agents, symbiotic microorganisms, and parasites are normal stimulants for the maturation of the immune system toward a balanced immune response. The theory predicts that lack of such stimulation leads to allergies and AUTOIMMUNE DISEASES.
The ability to attribute mental states (e.g., beliefs, desires, feelings, intentions, thoughts, etc.) to self and to others, allowing an individual to understand and infer behavior on the basis of the mental states. Difference or deficit in theory of mind is associated with ASPERGER SYNDROME; AUTISTIC DISORDER; and SCHIZOPHRENIA, etc.
