  This report provides a brief review of recently developed extended framework
for fundamental physics, designated as Quantum Field Mechanics and including
causally complete and intrinsically unified theory of explicitly emerging
elementary particles, their inherent properties, quantum and relativistic
behaviour, interactions and their results. Essential progress with respect to
usual theory is attained due to the unreduced, nonperturbative analysis of
arbitrary interaction process revealing a qualitatively new phenomenon of
dynamic multivaluedness of interaction results and their dynamically entangled
structure giving rise to universally defined dynamic complexity
(physics/9806002) and absent in usual, always perturbative and dynamically
single-valued models with the zero value of unreduced complexity (including
substitutes used for "complexity", "chaoticity", "self-organisation", etc.). It
is shown how the observed world structure, starting from elementary particles
and their interactions, dynamically emerges from the unreduced interaction
between two initially homogeneous, physically real protofields
(quant-ph/9902015, quant-ph/9902016). In that way one avoids arbitrary
imposition of abstract entities and unprovable postulates or "principles", let
alone "mysteries", of conventional theory, which now obtain unified, consistent
and realistic explanation in terms of unreduced dynamic complexity. We complete
the description of fundamental world structure emergence and properties by an
outline of experimental implications and resulting causally substantiated
change of research strategy.
