We define a notion of ghost centre of a Lie superalgebra g = g0 ⊕ g1 which is a sum of invariants with respect to the usual adjoint action (centre) and invariants with respect to a twisted adjoint action (“anticentre”). We calculate the anticentre in the case when the top external degree of g1 is a trivial g0-module. We describe the Harish-Chandra projection of the ghost centre for basic classi...

Color matrix elements of the ghost triangle diagram that appears in the triple gluon vertex and the ghost-ghost-gluon triangle diagram that appears in the ghost-gluon-ghost vertex are calculated. The ghost-ghost-gluon triangle contains a loop consisting of two color diagonal ghost and one gluon and a loop consisting of two color antisymmetric ghost and one gluon. Consequently the pQCD argument ...

A tissue model composed of erythrocyte ghosts was developed to study the effects of compartmentation on the MR signal acquired from biological tissues. This simple and flexible model offers control over the biophysical parameters that contribute to multicomponent signals arising from cellular systems. Cell density, size, intra- and extracellular composition, and membrane permeability can be ind...

Ghost variables are assignable variables that appear in program annotations but do not correspond to physical entities. They are used to facilitate specification and verification, e.g., by using a ghost variable to count the number of iterations of a loop, and also to express extra-functional behaviours. In this paper we give a formal model of ghost variables and show how they can be eliminated...

This paper is concerned with quantitative aspects of the fragmentation of red cells by heat and of the haemolysis which accompanies it. The former process involves a splitting of the cell into fragments which retain, at least in part, some of the properties of the intact cell (ability to swell in hypotonic media, ability to undergo certain shape transformations, etc.; see Ponder, 1949). The lat...

The chemical and enzymatic composition and the respiratory components of an intact membrane preparation, ghosts from Mycobacterium phlei, were compared to those of the electron transport particles. The ghosts were found to contain 5 to 7% of some of the soluble enzymes associated with the cytoplasm. In contrast, 97% of the total content of cytochromes b, cl + c, and a + a3 was found in the ghos...

Calcifying odontogenic cyst (COC) is a term used broadly to define lesions which were either cystic/solid in nature. However, a new term defining dentinogenic ghost cell tumor (DGCT), as its neoplastic counterpart, histopathologically showed the presence of dentinoid-like areas, ghost cells and ameloblastomatous-like odontogenic epithelium. This possesses a great challenge to an oral pathologis...

An adult female Sumatran rhinoceros was observed with a swelling in the left infraorbital region March 2017. The rapidly grew into mass. A radiograph revealed cystic radiolucent area maxilla. In June 2017, euthanized. At necropsy, mass measured 21 cm × 30 cm. Samples of mass, parotid gland, and masseter muscle were collected for histopathology (Hematoxylin & Eosin, Von Kossa, Masson’s trich...

The dependence of the gluon and ghost propagator in pure SU(3) gauge theory on the choice of Gribov copies in Landau gauge is studied. Simulations were performed on several lattice sizes at β = 5.8, 6.0 and 6.2. In the infrared region the ghost propagator turns out to depend on the choice, while the impact on the gluon propagator is not resolvable. Also the eigenvalue distribution of the Faddee...
