A Semi-Classical Schwinger-Keldysh Re-interpretation Of The 4D Majorana Fermion Mass Term
We offer a semi-classical re-interpretation of the 4D Majorana fermion mass
term as an `influence action' in the Schwinger-Keldysh formulation of fermionic

JAVANESE CULTURE DEPICTED IN THE USE OF KINSHIP ADDRESS TERMS
The Javanese system of kinship terms of address relies tightly on its social construction
mirroring not only culture but also point of view of the Javanese people. It is undeniable
that the society has long been structured vertically hierarchical. There is always upper to
lower social relationship among social practices. Hence it is manifested in the form of
Javanese speech levels illustrating that a speaker should consider both role and
circumstance. The levels of speech presumably fall into some smaller linguistic features,
one of which is address term particularly maintaining kinship relationship. Javanese culture
considers ascending generation as the polar asserting that father’s/mother’s big
brothers/sisters, father’s/mother’s big brother’s/sister’s sons/daughters, father’s/mother’s
big brother’s/sister’s son’s/daughter’s sons/daughters would be addressed as all terms
equivalent to big or older sibling
The New Resonating Valence Bond Method for Ab-Initio Electronic Simulations
The Resonating Valence Bond theory of the chemical bond was introduced soon
after the discovery of quantum mechanics and has contributed to explain the
role of electron correlation within a particularly simple and intuitive
approach where the chemical bond between two nearby atoms is described by one
or more singlet electron pairs. In this chapter Pauling's resonating valence
bond theory of the chemical bond is revisited within a new formulation,
introduced by P.W. Anderson after the discovery of High-Tc superconductivity.
It is shown that this intuitive picture of electron correlation becomes now
practical and efficient, since it allows us to faithfully exploit the locality
of the electron correlation, and to describe several new phases of matter, such
as Mott insulators, High-Tc superconductors, and spin liquid phases
