Title: Further evidence for a gravitational fixed point

Abstract

A theory of gravity with a generic action functional and minimally coupled to N matter fields has a nontrivial fixed point in the leading large N approximation. At this fixed point, the cosmological constant and Newton's constant are nonzero and UV relevant; the curvature squared terms are asymptotically free with marginal behavior; all higher order terms are irrelevant and can be set to zero by a suitable choice of cutoff function.

  • The problem of multicomponent liquid phase adsorption in fixed beds was studied further. In contrast to the earlier work, the method developed in this work is more efficient and also has a greater scope of applicability as it incorporates the use of the IAS (Ideal Adsorbed Solution Theory) method for the estimation of multicomponent adsorption equilibrium data. It was shown that the use of the more complex IAS method for the prediction of the isotherm data does not present insurmountable obstacles as once feared but provides much better prediction of carbon adsorption. An extension of the method to batch adsorptionmore » was shown to be straightforward and presented no special difficulty.« less
  • Assignment of a susceptibility locus for cutaneous malignant melanoma-dysplastic nevus (CMM/DN) to chromosome 1p remains controversial. The authors examined the relationship between CMM/DN and markers D1S47, PND, and D1S160 on seven new families (set B) plus updated versions of six previously reported families (set A). Three linkage analyses were performed: (1) CMM alone - all individuals without confirmed melanoma or borderline lesions were considered unaffected (model I); (2) CMM/DN with variable age at onset and sporadics (model II); and (3) CMM/DN using the model of Bale et al. (model III). For CMM alone and D1S47, Z[sub max] = 3.12 atmore » [theta] = .10. For D1S160 and CMM alone, Z[sub max] = 1.76 at [theta] = .10. PND showed no evidence for linkage to CMM alone. Models II and III showed strong evidence for linkage to D1S47, D1S160, and PND in the set A pedigrees but not in the set B families. The authors tested for homogeneity of CMM/DN (model II) by splitting families into two groups on the basis of (1) the proportion of CMM/DN cases and (2) the occurrence of immune-related tumors. In group 1 there was significant evidence of heterogeneity with both D1S47 and D1S160, and in group 2 there was significant evidence of heterogeneity with D1S160. Thus, diagnostic, clinical, and genetic heterogeneity are the likely reasons that previous studies have failed to confirm linkage of CMM/DN to chromosome 1p. The results showed significant evidence for a CMM locus linked to D1S47, as well as significant evidence for heterogeneity with only a subset of the families appearing linked to chromosome 1p. 38 refs., 1 fig., 5 tabs.« less
  • Glaucoma is a term used to describe a group of disorders which have in common a characteristic degeneration of the optic nerve associated with typical visual field defects and usually associated with elevated intraocular pressure. Two percent of white Americans and 6-10% of black Americans are affected by the disease. Compelling data indicate that susceptibility to many types of glaucoma is inherited. Hereditary juvenile glaucoma is one form of glaucoma that develops in children and is inherited as an autosomal dominant trait with high penetrance. Using a single large Caucasian pedigree affected with autosomal dominant juvenile glaucoma, Sheffield discovered positivemore » linkage to a group of markers that map to a 30 cM region on the long arm of chromosome 1 (1q21-q31). We have subsequently identified three unrelated Caucasian pedigrees affected with autosomal dominant juvenile glaucoma that also demonstrate linkage to this region on chromosome 1, with the highest combined lod score of 5.12 at theta = .05 for marker D1S218. The identification of critical recombinant individuals in our three pedigrees has allowed us to further localize the disease gene to a 12 cM region between markers D1S242 and D1S431. In addition, we have identified several pedigrees which do not demonstrate linkage to chromosome 1q, including a black family affected with autosomal dominant juvenile glaucoma that is indistinguishable clinically from the disorder affecting the caucasian pedigrees and three pedigrees affected with pigmentary dispersion syndrome, a form of glaucoma that also affects the juvenile population and is also inherited as an autosomal dominant trait. These findings provide evidence for genetic heterogeneity in juvenile glaucoma.« less
