The white-ivory somatic mutation test of Drosophila melanogaster is based on the reversion of the X-linked eye colour recessive mutation white-ivory to wild-type. Although the exact mechanism of white-ivory reversion is not quite understood, it has been suggested that such reversion, both in somatic and germ-line cells, could be due to the precise excision of the tandemly duplicated 2.96 kb DNA...

Many current-generation human immunodeficiency virus (HIV) vaccines induce specific T cells to control acute viremia, but their utility following infection with escape mutant virus is unclear. We studied reversion to wild type of an escape mutant simian-HIV in major histocompatibility complex-matched vaccinated pigtail macaques. High levels of vaccine-induced CD8+ T cells strongly correlated wi...

In this paper, we present a model of implementation where infeasible allocations are converted into feasible ones through a process of renegotiation that is represented by a reversion function. We describe the maximal set of Social Choice Correspondences that can be implemented in Nash Equilibrium in a class of reversion functions that punish agents for infeasibilities. This is used to study th...

In the present study, the presence of brass mesh on the bond strength of aluminum (AA1050) strips in the cold roll bonding process was investigated. The influence of various process parameters including reduction in thickness, pre-rolling annealing, initial thickness of the strips, and post-rolling annealing was also considered. After cold roll bonding process, peeling test was carried out and ...

Studies on the reversion characteristics of Escherichia coli strains carrying various mutations in the pts region have led to the recognition of a mutation, suc-1, with a previously undescribed phenotype. Strains carrying the suc-1 mutation grow normally on most sources of carbon but are unable to utilize succinate effectively. The suc-1 mutation can be separated genetically from the tightly li...

The Rosenberg-Hastings paper (4) defends a model much like that of Foster (1) and argues that the observed mutagenesis contradicts predictions of the amplification model. On the contrary, amplification indirectly causes weak mutagenesis and allows that mutagenesis to have a detectable effect on lac reversion. However, this mutagenesis is a minor side effect that is neither sufficient nor necess...

Protoplasts of Bacillus megaterium readily reverted to bacillary form in liquid media and when plated in a soft-agar layer onto the surface of appropriate agar media. Three phases of the reversion sequence could be differentiated by phase contrast microscopy: (i) increase in size of the individual protoplasts, (ii) non oriented division of the protoplasts and (iii) outgrowth of the bacillary fo...

We study errors of quantum annealing and simulated annealing to highlight better performance of quantum annealing over simulated annealing. Quantum annealing and simulated annealing perform optimization through a quantum adiabatic evolution and a quasi-static evolution respectively. In both methods, dynamics across a phase transition plays a crucial role. The Kibble-Zurek mechanism is known as ...

backgrounds: evidence is accumulating to support disruption of tissue architecture as a powerful event in tumor formation. for the past four decades, intensive cancer research with the premise of “cancer as a cell based-disease” focused on finding oncogenes or tumor suppressor genes. however, the role of the tissue architecture was neglected. three dimensional (3d) cell cultures which can recap...

OBJECTIVE We examined the impact of adherence to the Alternative Healthy Eating Index (AHEI), a set of dietary guidelines targeting major chronic diseases, on metabolic syndrome (MetS) reversion in a middle-aged population. RESEARCH DESIGN AND METHODS Analyses were carried out on the 339 participants (28% women, mean age 56.4 years) from the Whitehall II study with MetS as defined by the Nati...
