Monazite grains from Greater Himalayan Sequence gneisses, Langtang valley, Nepal, were chemically mapped and then dated in situ via Th–Pb ion-microprobe analysis. Correlation of ages and chemistry reveals at least five different generations of monazite, ranging from c. 9 to >300 Ma. Petrological models of monazite chemistry provide a link between these generations and the thermal evolution of t...

Metamorphic Testing Techniques to Detect Defects in Applications without Test Oracles Christian Murphy Applications in the fields of scientific computing, simulation, optimization, machine learning, etc. are sometimes said to be “non-testable programs” because there is no reliable test oracle to indicate what the correct output should be for arbitrary input. In some cases, it may be impossible ...

Informed by object-oriented and relational perspectives on space, this article argues for morecomplex accounts of architectural and urban problématiques. Starting from Isabelle Stengers’distinction between la ville complexe and la ville compliquée, it discusses the 2010 exhibition“Building for Brussels. Architecture and Urban Transformation in Europe” (BOZAR, Centre ofFine Arts ...

Metamorphic epitaxy technique offers the possibility of combining the advantages of low-cost and manufacturability of GaAs substrates and the high performance of InP-based devices. This paper will present the recent development of metamorphic HEMTs and HBTs and discuss their readiness for commercialization.

This is a survey of M-regularity and its applications, expanding on lectures given by the second author at the Seattle conference, in August 2005, and at the Luminy workshop " Géométrie Algébrique Complexe " , in October 2005 1 .

In this article we examine the problem of dynamic self-reconfiguration of a class of modular robotic systems referred to as metumorpkic systems. A metamorphic robotic system is a collection of mechatronic modules, each of which has the ability to connect, disconnect, and climb over adjacent modules. A change in the macroscopic morphology results from the locomotion of each module over its neigh...

The strain relaxation mechanism and defect properties of compositionally step-graded InAsyP1−y buffers grown by molecular beam epitaxy on InP have been investigated. InAsP layers having lattice misfits ranging from 1% to 1.4% with respect to InP, as well as subsequently grown lattice matched In0.69Ga0.31As overlayers on the metamorphic buffers were explored on both 100 and 2° offcut 100 InP sub...

Latent precursors or stem cells of neural crest origin are present in a variety of post-embryonic tissues. Although these cells are of biomedical interest for roles in human health and disease, their potential evolutionary significance has been underappreciated. As a first step towards elucidating the contributions of such cells to the evolution of vertebrate form, we investigated the relative ...

In this paper, we describe an example of a hyperkähler quotient of a Banach manifold by a Banach Lie group. Although the initial manifold is not diffeomorphic to a Hilbert manifold (not even to a manifold modelled on a reflexive Banach space), the quotient space obtained is a Hilbert manifold, which can furthermore be identified either with the cotangent space of a connected component Gr res of...

A tropical curve Γ is a metric graph with possibly unbounded edges, and tropical rational functions are continuous piecewise linear functions with integer slopes. We define the complete linear system |D| of a divisor D on a tropical curve Γ analogously to the classical counterpart. We investigate the structure of |D| as a cell complex and show that linear systems are quotients of tropical modul...
