Amomi Fructus has been used to treat digestive diseases in the context of traditional Chinese medicine, so we evaluated the effects of a volatile oil from Amomum villosum (VOA) on intestinal mucositis induced by 5-fluorouracil (5-FU). We measured the effect of VOA and its main active constituent, bornyl acetate (BA), on body weight, food intake, diarrhea, inflammatory cytokines, the mucosal bar...

Samples of active and cured compost from across the U.S. are examined for volatile organic acids (VOA) in relation to other microbiological and chemical properties. VOA are considered important because they reflect temporal microbiological properties of active and cured compost that influence the potential for compost to become odorous and phytotoxic. Data collected from 712 compost samples rev...

Acori Graminei Rhizoma is well known for the beneficial effects on CNS disorders in traditional medicine. Though it is frequently prescribed in formulations for brain tumors, the anti-glioma effect has not been examined. We used volatile oil of Acori Graminei Rhizoma (VOA) and human glioblastoma multiforme (GBM) cells in this study. We found that VOA exhibited greater growth suppression in p53 ...

In this article we study a VOA with two Miyamoto involutions generating S3. In [M3], Miyamoto showed that a VOA generated by two conformal vectors whose Miyamoto involutions generate an automorphism group isomorphic to S3 is isomorphic to one of the four candidates he listed. We construct one of them and prove that our VOA is actually the same as VA(e, f) studied by Miyamoto. We also show that ...

In [M2], the author has defined an automorphism τ of a vertex operator algebra (VOA) of order 2 using a sub VOA isomorphic to Ising model L(12 , 0). We here define an automorphism of VOA of order 3 by using a sub VOA isomorphic to a direct sum of 3-state Potts models L(45 , 0) and an its module L( 4 5 , 3). If V is the moonshine VOA V ♮, the defined automorphism is a 3A element of the monster s...

Energy-momentum tensor for the toroidal Lie algebras. Abstract. We construct vertex operator representations for the full (N + 1)-toroidal Lie algebra g. We associate with g a toroidal vertex operator algebra, which is a tensor product of an affine VOA, a sub-VOA of a hyperbolic lattice VOA, affine sl N VOA and a twisted Heisenberg-Virasoro VOA. The modules for the toroidal VOA are also modules...

We use uniqueness of a VOA (vertex operator algebra) extension of (V + EE8) 3 to a Moonshine type VOA to give a new existence proof of a finite simple group of Monster type. The proof is relatively direct. Our methods depend on VOA representation theory and are free of many special calculations which traditionally occur in theory of the Monster.

We study a simple vertex operator algebra (VOA) V containing a set of mutually orthogonal simple conformal vectors ei : i = 1, ..., n with central charge 12 such that the sum is the Virasoro element. In [M3], the author showed that it defines two mutually orthogonal binary linear codes D and S. We prove that V is the only irreducible V -module if D = S⊥. Applying the way of constructing VOA giv...

In this paper, we study the structure of a general framed vertex operator algebra. We show that the structure codes (C,D) of a framed VOA V satisfy certain duality conditions. As a consequence, we prove that every framed VOA is a simple current extension of the associated binary code VOA VC . This result would give a prospect on the classification of framed vertex operator algebras. In addition...

We report on the fabrication and characterization of a single-mode fiber variable optical attenuator (VOA) based on a ferrofluid shutter actuated by a magnetic field created by a low voltage electromagnet. We compare the performance of a VOA using oil-based ferrofluid, with one VOA using water-based 12 ferrofluid, and demonstrate broadband optical attenuation of up to 28 dB with polarization de...
