We describe and apply choice models, including generalizations of logit called "mixed logits," that do not exhibit the restrictive "independence from irrelevant alternatives" property and can approximate any substitution pattern. The models are estimated on data from a stated-preference survey that elicited customers’ preferences among gas, electric, methanol, and CNG vehicles with various attr...

We have prepared multifunctional magnetic mesoporous Fe-CaSiO3 materials using triblock copolymer (P123) as a structure-directing agent. The effects of Fe substitution on the mesoporous structure, in vitro bioactivity, magnetic heating ability and drug delivery property of mesoporous CaSiO3 materials were investigated. Mesoporous Fe-CaSiO3 materials had similar mesoporous channels (5-6 nm) with...

Mutations in superoxide dismutase 1 (SOD1) polypeptides cause a form of familial amyotrophic lateral sclerosis (FALS). In different kindreds, harboring different mutations, the duration of illness tends to be similar for a given mutation. For example, patients inheriting a substitution of valine for alanine at position four (A4V) average a 1.5 year life expectancy after the onset of symptoms, w...

In [13], Kleene formulated a truth-notion called "readability" for formulas of intuitionistic number theory(1). David Nelson(2) showed that every number-theoretic formula deducible in the intuitionistic predicate calculus(3) (stated by means of schemata, without proposition or predicate variables) from realizable number-theoretic formulas is realizable. In particular, then, every formula in the...

The aim of this paper is to present the notion of higher-dimensional syntax, which is a hierarchy of languages. Each term of a n-dimensional language will be typed by terms of the underlying n ? 1-dimensional language. This is an application of the emerging higher-dimensional category notions. On the lower dimensions live notions of syntax which are already known. So dimension zero corresponds ...

Abstract Mechanical properties consisting of the bulk modulus, shear Young’s Poisson’s ratio, etc., are key factors in determining practical applications MAX phases. These mechanical mainly dependent on strength M-X and M-A bonds. In this study, a novel strategy based crystal graph convolution neural network (CGCNN) model has been successfully employed to tune these Ti 3 AlC 2 -based phases via...

Zeolites, both natural and synthetic, are certainly some of the most versatile minerals for their applications. Since 1940s, they have been used in chemical industry as catalysts, adsorbents ion exchanger extensively, development practical usage is expected to continue upon years. Their versatility result combination peculiar indispensable properties, each which can be found other material a si...

The present study set out to investigate the effect of teaching substitution as a kind of grammatical cohesion on the true identification of confusing substitution elements with cohesive or non-cohesive roles in different contexts and also the production of modal, reporting and conditional contexts through clausal substitution acquaintance. To this end, the following procedures were taken. Firs...

The structure and crystallization of silver-doped germano-gallate glasses for substitution potassium barium ions have been investigated. By means Raman spectroscopy, a structural study has carried out revealing glass network depolymerization with the formation non-bridging oxygens likely localized on germanium tetrahedra when concentration increases. These modifications do not appear to signifi...
