A noncommutative version of the usual electro-weak theory is constructed. We discuss how to overcome the two major problems: 1) although we can have noncommuta-tive U (n) (which we denote by U ⋆ (n)) gauge theory we cannot have noncommutative SU (n) and 2) the charges in noncommutative QED are quantized to just 0, ±1. We show how the problem with charge quantization, as well as with the gauge g...

This paper re-addresses the old problem of providing a categorical model for Intuitionistic Linear Logic (ILL). In particular we compare the now standard model proposed by Seely to the lesser known one proposed by Benton, Bierman, Hyland and de Paiva. Surprisingly we nd that Seely's model is unsound in that it does not preserve equality of proofs. We shall propose how to adapt Seely's deenition...

Background: Filial piety is a fundamental virtue that defines children’s care-giving obligation to older parents in Chinese families. This study aims to evaluate whether gender difference exists in the expectation and receipt of filial piety among U.S Chinese older adults. Methods: Data were drawn from the PINE study, a population-based study of U.S. Chinese older adults aged 60 and above in th...

Horizontal black surfaces are usually very attractive to polarotactic aquatic insects, since they generally reXect highly and horizontally polarized light, and thus imitate water surfaces. We monitored highly polarizing black burnt-up stubble-Welds, but surprisingly never found aquatic insects or their carcasses in the ash, although Xying polarotactic insects were abundant in the area, which we...

We consider the problem of modeling a helicopter’s dynamics based on state-action trajectories collected from it. The contribution of this paper is two-fold. First, we consider the linear models such as learned by CIFER (the industry standard in helicopter identification), and show that the linear parameterization makes certain properties of dynamical systems, such as inertia, fundamentally dif...

is quite strange that, in this chapter, some results do concern constant delays as well. I would have preferred it considered in a separate chapter or, at least, comments and analysis could have been unified in another section. Part III (Chapter 8) concludes the book with input–output stability analysis, mainly using the small gain theorem. First the method of comparison systems (embedding the ...

the conditional formal potential, e°′of methyldopa has been studied by cyclic voltammetry at the surface of activated glassy carbon electrode (agce) as the working electrode in different ph phosphate buffered solutions. the experimental standard redox potential, e°′, of methyldopa is obtained to be 0.72 mv versus she (standard hydrogen electrode). e°′ values have also been calculated with the a...

the regulated price policy may be implemented for some products. it is generally implemented for some products such as electricity, natural gas, water and so on that are supplied as monopolist. the regulated price shock on these products may lead to an adjustment in the endowments of primary factors. the aim of this paper is to investigate the effects of a regulated price shock on price indices...

Data envelopment analysis (DEA) is a common technique in measuring the relative efficiency of a set of decision making units (DMUs) with multiple inputs and multiple outputs. ‎‎Standard DEA models are ‎‎quite limited models‎, ‎in the sense that they do not consider a DMU ‎‎at different times‎. ‎To resolve this problem‎, ‎DEA models with dynamic ‎‎structures have been proposed‎.‎In a recent pape...
