An economy consisting of n>=2 different types of consumers and one publicly owned natural monopoly is under consideration. The preferences of the consumers are assumed to be linear in money and the demand curves are assumed not to cross. We also suppose that the net utility from consumption is so high that we do not have to consider the individual rationality constraints. Given these assumptions,
Classical conditioning of motor responses, e.g., the eyeblink response, depends on the cerebellum. In the theoretical works of David Marr (1969) and James Albus (1971), it was proposed that Purkinje cells in the cerebellar cortex learn to associate the neutral conditioned stimulus with the response. Since their work, several studies have provided data that are consistent with this suggestion, but
Carotenoids play a number of roles in living organisms. In addition to their well-know light-harvesting function in photosynthesis, they have also photoprotective and antioxidative functions in various physiological systems. Studies of dynamics of carotenoid excited states have established the following scheme: after excitation of a carotenoid to its S2 state (1Bu+), a fast relaxation to the Si st
Abstract in UndeterminedLet us by first-order beliefs mean beliefs about the world, such as the belief that it will rain tomorrow, and by second-order beliefs let us mean beliefs about the reliability of first-order, belief-forming processes. In formal epistemology, coherence has been studied, with much ingenuity and precision, for sets of first-order beliefs. However, to the best of our knowledge
Insertions and deletions of nucleotides in the genes encoding the variable domains of antibodies are natural components of the hypermutation process, which may expand the available repertoire of hypervariable loop lengths and conformations. Although insertion of amino acids has also been utilized in antibody engineering, little is known about the functional consequences of such modifications. To i
Polysulfone has been sulfophenylated by lithiation and anionic reaction with 2-sulfobenzoic acid cyclic anhydride. This provides a new convenient method to modify polysulfones by attaching pendant sulfonated phenyl groups via ketone links. Membranes of the sulfophenylated polysulfones show promise for use in proton-exchange-membrane fuel cells. For example, a membrane with 0.9 sulfophenyl units pe
This article argues that the body of foreign direct investment (FDI) literature in general and the ownership, location, and internalization (OLI) paradigm in particular would be enriched if finance-specific factors are explicitly incorporated as drivers of FDI. We suggest that financial strategies involving factors such as debt/equity swaps or equity listings in foreign equity markets affect the f
Bird migration has been assumed, mostly implicitly, to represent a distinct class of animal behavior, with deep and strong homologies in the various phenotypic expressions of migratory behavior between different taxa. Here the evidence for the existence of what could be called a "migratory syndrome," a tightly integrated, old group of adaptive traits that enables birds to commit themselves to high
The written language situation of the minority populations of China is described, with emphasis on script reforms & the creation of new scripts after the founding of the People's Republic in 1949. Despite the efforts of scholars, the new scripts have had little success. Despite the fact that many of these scripts meet some significant criteria for "good writing systems," they also pose problem
GaAs and GaMnAs compounds grown by low temperature (LT) molecular beam epitaxy (MBE), are promising materials for fabricating novel devices. LT-GaAs has already been used in new devices, as it has subpicosecond carrier lifetimes, good carrier mobility and high dark resistivity. GaMnAs compounds are candidates for integrating ferromagnetic materials into semiconductor devices, as they can become fe
The elemental composition of 10 samples of Spanish moss Tillandsia usneoides L. collected mainly in forested areas near Tallahassee, Florida, has been compared to the composition of the ambient aerosol particle background in the forest measured as a function of particle size. For forest samples, moss composition is similar to the composition of aerosol particles greater than about 0.5-μm diameter
In the inversion in R 2 of the exponential Radon transform, a scalar function f is found from its integrals, with exponential weight functions, over lines. In this paper we demonstrate how to define two different kinds of exponential Radon transforms for vector fields in R 2 in a natural way. It is shown that having data from these exponential vectorial Radon transforms it is possible to reconstru
The ability to draw other agents’ attention to objects and events is an important skill on the critical path to effective human-robot collaboration. People use the act of pointing to draw other people’s attention to objects and events for a wide range of purposes. While there is significant work that aims to understand people’s pointing behavior, there is little work analyzing how people interpret
