Nonlinear normal modes and spectral submanifolds: existence, uniqueness and use in model reduction
, 2016We propose a unified approach to nonlinear modal analysis in dissipative oscillatory systems. This approach eliminates conflicting definitions, covers both autonomous and time-dependent systems and provides exact mathematical existence, uniqueness and ...

That is the question. The search for a single theory of everything is as old as science itself, and is now the beat of quantum cosmologists. But some basic tenets that inform the quest are being challenged.

Fourier Phase Retrieval: Uniqueness and Algorithms
arXiv.org, 2017The problem of recovering a signal from its phaseless Fourier transform measurements, called Fourier phase retrieval, arises in many applications in engineering and science. Fourier phase retrieval poses fundamental theoretical and algorithmic challenges.

CYP1B1: A Unique Gene with Unique Characteristics
Current Drug Metabolism, 2015CYP1B1, a recently described dioxin inducible oxidoreductase, is a member of the cytochrome P450 superfamily involved in the metabolism of estradiol, retinol, benzo[a]pyrene, tamoxifen, melatonin, sterols etc. It plays important roles in numerous physiological processes and is expressed at mRNA level in many tissues and anatomical compartments.

Unique Profession, Unique Preparation
Journal of Architectural Education (1947-1974), 1962Architecture is the only art of habitable space; it is the business of the architect, and of the architect alone, to give to such space, experienced four-dimensionally, visual meaning. Therefore, says Philip Thiel, visual education should have a central place, next to design itself, in the curriculum of any school of architecture, and to be effective ...

Global Uniqueness and Solvability for Tensor Complementarity Problems
Journal of Optimization Theory and Applications, 2015Recently, the tensor complementarity problem has been investigated in the literature. An important question involving the property of global uniqueness and solvability for a class of tensor complementarity problems was proposed by Song and Qi (J Optim ...

Uniquely primate, uniquely human
Developmental Science, 1998Two hypotheses about primate cognition are proposed. First, it is proposed that primates, but not other mammals, understand categories of relations among external entities. In the physical domain primates have special skills in tasks such as oddity, transitivity, and relation matching that require facility with relational categories; in the social ...

AbstractLet L be a finitely generated field extension of a field K. The order of inseparability of L/K is the minimum of {n|[L:S] = pn where S is a separable extension of K}. If V is a subfield of L/K, then its order of inseparability is less than or equal to that of L/K.

In general equilibrium theory, equilibrium prices may be interpreted as those prices which coordinate the buying and selling plans of all the various agents in the economy; equivalently, they may be interpreted as the values of the commodities. Such values will only be well defined if there is only one system of coordinating prices, that is, if the ...
