Endovascular therapy of arterial occlusive disease has made impressive progress since the first balloon angioplasty conceived by Dr Charles T. Dotter in 1964, followed by the first peripheral balloon angioplasty by Dr Andreas Gruntzig in 1974. Each advancement has frequently faced skepticism after the initial clinical experience. Thankfully, skepticism was met in kind with research seeking faci...

Abstract The recent Covid-19 global health crisis not only brings into sharp relief the current problems afflicting international intellectual property regime (IIPR) but also calls question its legitimacy as an authority. Against this backdrop, article aims to launch investigation of IIPR, co-ordinative authority, designed protect IP rights without prejudice trade norms. Drawing on Raz’s servic...

In this paper circulant matrices in max-plus algebra are presented. Circulant matrices are special form of matrices which are entered by vector of inputs. For special types of matrices such as circulant matrices, the computation can often be performed in the simpler way than in the general case. The so-called max-plus algebra is useful for investigation of discrete events systems and the sequen...

Since its discovery more than 25 years ago, the kinase AKT has become a central figure in cell signaling. We highlight some of the landmark findings in those 25 years that contributed to our understanding of the regulation and function of AKT in directing cellular processes and behavior. Future progress toward fully understanding the roles of AKT in cell, tissue, and organismal biology will dep...

Government intervention often gives rise to contests in which the possible ‘prizes’ are determined by the existing status-quo and some new publicpolicy proposal . In this paper we study the general class of such two-player public-policy contests and examine the effect of a change in the proposed policy, a change that may affect the payoffs of the two contestants, on their effort and performance...

This article is a critique of the U.S. National Academy of Engineering’s report, Grand Challenges for Engineering, based upon the “technocratic view” of progress as defined by historian Leo Marx and as exemplified by the public works of Robert Moses, including the 1964 World’s Fair, as well as technological determinist narratives on the digital age drawn from contemporary culture. While the soc...
