Acupuncture and needle-stimulation, differences in concepts and methods
Based on related elaboration of the Yellow Emperorâs Canon of Medicine, this article analyzed and summarized the clinical meaning, application principles and the basic operating methods of Traditional Acupuncture (TA), and demonstrated that the TA is completely different to modern needle stimulation. TA has a specific application background, direct-viewing thinking mode and clear operational connotation. The key of operation in TA is how to grasp and control Qi, which typically reflect the unique image of the Chinese civilization with intuitive perceptual characteristics of thinking. In contrast, modern needle-stimulation uses needles as a stimulus, to activate a series of physical and functional reactions in a body. There have great differences between the two. It was indicated that correctly understanding with the basic principle and specific meaning of TA is very important in acupuncture clinical and research works.published_or_final_versio

Acupoints originated from the ancient belief that diseases were caused by ghosts and evil spirits haunting the body. Acupoints were believed to be where the ghost and evil spirits hid, and thus, the rationale for healing was to expel the ghost and evil spirits directly from the diseased body part. Huang Di Nei Jing (Yellow Emperor's Inner Canon), an ancient Chinese medical text, mentions "pain as the point" in describing how to locate and manipulate the acupoint. During the era in which Huang Di Nei Jing (Yellow Emperor's Inner Canon) was written, the wide applications of filiform needle acupuncture expedited the amalgamation between acupoint and meridian theories. As a result, the concept of acupoints were further strengthened and expanded in their structures and functions. In the meantime, acupoints had developed to become the key points for qi and blood circulating inside the human body rather than where evil spirits hid. The formation and finalization of acupoints actually reveal a historical progression from witchcraft to medicine. © 2012 Shanghai Research Institute of Acupuncture and Meridian and Springer-Verlag Berlin Heidelberg.postprin
Hom-quantum groups I: quasi-triangular Hom-bialgebras
We introduce a Hom-type generalization of quantum groups, called
quasi-triangular Hom-bialgebras. They are non-associative and non-coassociative
analogues of Drinfel'd's quasi-triangular bialgebras, in which the
non-(co)associativity is controlled by a twisting map. A family of
quasi-triangular Hom-bialgebras can be constructed from any quasi-triangular
bialgebra, such as Drinfel'd's quantum enveloping algebras. Each
quasi-triangular Hom-bialgebra comes with a solution of the quantum
Hom-Yang-Baxter equation, which is a non-associative version of the quantum
Yang-Baxter equation. Solutions of the Hom-Yang-Baxter equation can be obtained
from modules of suitable quasi-triangular Hom-bialgebras.Comment: 21 page

Zooming in on local level statistics by supersymmetric extension of free probability
We consider unitary ensembles of Hermitian NxN matrices H with a confining
potential NV where V is analytic and uniformly convex. From work by
Zinn-Justin, Collins, and Guionnet and Maida it is known that the large-N limit
of the characteristic function for a finite-rank Fourier variable K is
determined by the Voiculescu R-transform, a key object in free probability
theory. Going beyond these results, we argue that the same holds true when the
finite-rank operator K has the form that is required by the Wegner-Efetov
supersymmetry method of integration over commuting and anti-commuting
variables. This insight leads to a potent new technique for the study of local
statistics, e.g., level correlations. We illustrate the new technique by
demonstrating universality in a random matrix model of stochastic scattering.Comment: 38 pages, 3 figures, published version, minor changes in Section
Rigorous Derivation of the Gross-Pitaevskii Equation
The time dependent Gross-Pitaevskii equation describes the dynamics of
initially trapped Bose-Einstein condensates. We present a rigorous proof of
this fact starting from a many-body bosonic Schroedinger equation with a short
scale repulsive interaction in the dilute limit. Our proof shows the
persistence of an explicit short scale correlation structure in the condensate.Comment: 4 pages, 1 figur
