Syntactic foam is being increasingly conceived for aero engine applications to enhance overall structural reliability under impact loading . Systematic compressive tests without and with lateral confinement are carried out investigate the deformation failure of an epoxy syntactic (ESF) at quasi-static 0.01/s, medium rate 10–100/s high strain rates 500–1100/s gradually increasing temperatures fr...

One loop contributions to the Higgs boson masses and mixings from the chargino sector consisting of the chargino, the W, and the charged Higgs boson (χ −W − H) exchanges and including the effects of large CP violating phases are computed. It is found that the chargino sector makes a large contribution to the mixings of the CP even and the CP odd Higgs sectors through the induced one loop effect...

The relationship between psychology and phenomenology is not one that is easily traceable (for a discussion on the difficulties of this see, e.g., Graumann 1991). One of the reasons for this opaque matter is that neither psychology nor phenomenology can be defined as one subject area. Both have developed over time with different persons representing varying approaches and others yet again furth...

Three decay mechanisms are derived systematically from the QCD Lagrangian using the field correlator method. Resulting operators contain no arbitrary parameters and depend only on characteristics of field correlators known from lattice and analytic calculations. When compared to existing phenomenological models, parameters are in good agreement with the corresponding fitted values.

This paper proposes that adopting a ‘phenomenological stance’ enables a distinctive kind of empathy, which is required in order to understand forms of experience that occur in psychiatric illness and elsewhere. For the most part, we interpret other people’s experiences against the backdrop of a shared world. Hence our attempts to appreciate interpersonal differences do not call into question a ...

In this note we study the correspondence between the " relativistic spin foam " model introduced by Barrett, Crane and Baez and the so(4) Plebanski action. We argue that the so(4) Plebanski model is the continuum analog of the relativistic spin foam model. We prove that the Plebanski action possess four phases, one of which is gravity and outline the discrepancy between this model and the model...

Any viable theory of modified Newtonian dynamics (MOND) as modified gravity is likely to require fields in addition to the usual tensor field of General Relativity. For such theories the MOND phenomenology emerges as an effective fifth force probably associated with a scalar field. Here I consider the constraints imposed upon such theories by solar system phenomenology, primarily by the absence...

A phenomenological model for the dissipation of scalar fluctuations due to the straining by the fluid motion is proposed in this Brief Communication. An explicit equation is obtained for the time evolution of the probability distribution function of a coarse-grained scalar concentration. The model relies on a self-convolution process. We first present this model in the Batchelor regime and then...

Freedom Penultimate draft. Please cite only final version in The Routledge Companion to Phenomenology. Human freedom was Jean-Paul Sartre's central philosophical preoccupation throughout his career. It is hardly surprising, therefore, that the cornerstone of his moral and political thought, Being and Nothingness, contains an extensive and subtle account of the metaphysical freedom that he consi...

We discuss the possibility of a smooth transition from the pre-to the post-big bang regime, in the context of the lowest-order string eeective action (without higher-derivative corrections), taking into account with a phenomenological model of source the repulsive gravitational eeects due to the back-reaction of the quantum uctuations outside the horizon. We determine a set of necessary conditi...
