This paper locates the notion of technological revolutions in the NeoSchumpeterian effort to understand innovation and to identify the regularities, continuities and discontinuities in the process of innovation. It looks at the microand meso-foundations of the patterns observed in the evolution of technical change and the interrelations with the context that shape the rhythm and direction of in...

In the last ten years or so, exemplar theory has enjoyed much growth in the field of phonetics. More recently, attempts have been made to apply exemplar theory to syntactic phenomena. Thus far, the issue of unifying phonetic and syntactic exemplartheoretic models has not been addressed. This paper presents a single over-arching exemplar-based model of constituent interactions across both lingui...

During routine dissection, we found a rare case of an aberrant muscular slip originating from the pectoralis major called as the "chondroepitrochlearis / thoracoepicondylaris / costohumeralis" and an anomalous slip from the latissimus dorsi called as "axillary arch of Langer / musculus dorsoepitrochlearis" in the same axilla. Interestingly, these two slips found to have a common insertion after...

Adamanasuchus eisenhardtae is a new genus and species of aetosaur from the Upper Triassic (Adamanian: late Carnian) Blue Mesa Member of the Petrified Forest Formation (Chinle Group) in the Petrified Forest National Park, east-central Arizona. Known from part of its dorsal armor, caudal vertebrae, and a femur, A. eisenhardtae is distinguished by relatively narrow and arched paramedian osteoderms...

A photogeologic and physical modeling study indicates that Hebes Chasma, Mars, formed by collapse of the megaregolith. Local heating facilitated drainage of ~105 km3 of brines and entrained particulates through fractures in the chasma fl oor and into a regional aquifer. A megaregolith rich in salts and water is implied by massive, low-gradient allochthonous fl ows that terminate in deep pits an...

Infantile spasm (IS) is a specific rare type of seizure seen in an epilepsy syndrome of infancy; it is also known as West syndrome and is characterized by developmental regression and a specific pattern on electroencephalography (EEG) testing called hypsarrhythmia (chaotic brain waves). Gastroesophageal Reflux Disease (GERD) is considered a common clinical problem in every day paediatrics clini...

Pedestrian crowds often have been modeled as many-particle systems, usually using computer models known as multiagent simulations. The key challenge in modeling crowds is to develop rules that guide how the particles or agents interact with each other in a way that faithfully reproduces paths and behaviors commonly seen in real human crowds. Here, we propose a simple and intuitive formulation o...

The theory behind the success of adaptive reweighting and combining algorithms (arcing) such as Adaboost (Freund & Schapire, 1996a, 1997) and others in reducing generalization error has not been well understood. By formulating prediction as a game where one player makes a selection from instances in the training set and the other a convex linear combination of predictors from a finite set, exis...

Darwinism offers a highly abstract and general meta-theoretical framework to help understand both natural and social evolution. This framework is of significance for ecological economics because it addresses the evolution and coevolution of biological systems and sets of human institutions. This paper outlines this framework and charts its historical origins since the time of Darwin. It is sugg...

This paper presents an approach to describing the three dimensional shape of a violin plate in mathematical form. The shape description begins with standard contour lines and ends with an equation for a surface in three dimensional space. The traditional specification of cross sectional arching is unnecessary. Advantages of this approach are that it employs simple and universal description of p...
