As is well known, the image of J-homomorphism in the stable homotopy groups of spheres is described in terms of the first line of Adams-Novikov E2-term. In this paper we consider an algebraic analogue of the image J using the spectrum T (m)(j) defined by Ravenel and determine the Adams-Novikov first line for small values of j.

Matrix metalloproteinases (MMP) are crucial for homeostasis (tissue remodelling and repair, bone growth, wound healing, etc.) and pathology (metastasis, angiogenesis, aneurysm rupture, etc.). Upregulated MMPs from macrophages are thus a two-edged sword, playing both defensive and aggressive roles. The related family of ADAMs (a disintegrin and a metalloproteinase) is sometimes overlooked becaus...

in this paper‎, ‎we prove a multiplicity result for some biharmonic elliptic equation of kirchhoff type and involving nonlinearities with critical exponential growth at infinity‎. ‎using some variational arguments and exploiting the symmetries of the problem‎, ‎we establish a multiplicity result giving two nontrivial solutions‎.

Proteolytic conversion (shedding) of membrane-bound proteins to soluble forms is a novel regulatory mechanism mediated by enzymes called a disintegrin and metalloproteases (ADAMs). In this review, the potential importance of ADAMs in vascular physiology and disease, especially in relation to atherosclerosis, will be highlighted.

Earlier work by the author and coworkers (Adams & Whittaker, 1948; Adams, 1949; Whittaker, 1949; Mounter & Whittaker, 1950; Mounter, 1951) has shown that the so-called 'true' or 'specific' cholinesterases of erythrocytes, brain and cobra venom, previously believed to act only on acetylcholine and a few other esters, are in reality capable of hydrolysing a wide range of non-choline esters, 3:3-d...

The goal of this work is the construction of the analogue to the Adams spectral sequence in cobordism theory, calculation of the ring of cohomology operations in this theory, and also a number of applications: to the problem of computing homotopy groups and the classical Adams spectral sequence, fixed points of transformations of period p, and others.

ECOMBINATION of auxotrophic and inhibitor resistant characters from crosses of Nocardia canicruria and Nocardia erythropolis have been previously reported (ADAMS and BRADLEY 1963; ADAMS 1964; BROWNELL and ADAMS 1967). Substrains derived from N . canicruria were observed to mate only with substrains derived from N . erythropolis while substrains of homologous origin were incompatible. From these...

The Atlas and Database of Air Medical Services (ADAMS) is a web-based, password-protected, geographic information system containing data on air medical service main and satellite base helipads, communication centers, rotorwing aircraft, and major receiving hospitals for trauma in the United States. ADAMS initially was developed to provide the geographic information needed to support realtime, w...
