Although several studies have aimed to identify mare's milk proteins, only the major whey proteins and some caseins have yet been characterized. Incomplete sequencing of the equine genome and the difficulty of recovering highly hydrophobic proteins mean that little is known to date about the proteins associated with milk fat globules, which have been shown to play an important role in newborns' defense mechanisms. The fat fraction, in particular the distribution of unsaturated fatty acids, has been more extensively studied, but complex lipids are only partially elucidated. This study reports a 2-DE approach combined with a powerful method for de novo protein sequencing, and quali-quantitative data on complex lipid composition determined by high performance TLC (HPTLC) and GC. The presence in mare's milk of long-chain highly unsaturated fatty acids, and the evidence of close similarity between equine and human milk fat globule membrane proteins, support the use of mare's milk for human nutrition. 相似文献

In this paper we describe a modeling framework aimed at facilitating the customization and deployment of artificial intelligence
(AI) scheduling technology in real-world contexts. Specifically, we describe an architecture aimed at facilitating software
product line development in the context of scheduling systems. The framework is based on two layers of abstraction: a first
layer providing an interface with the scheduling technology, on top of which we define a formalism to abstract domain-specific
concepts. We show how this two-layer modeling framework provides a versatile formalism for defining user-oriented problem
abstractions, which is pivotal for facilitating interaction between domain experts and technologists. Moreover, we describe
a graphical user interface (GUI)-enhanced tool which allows the domain expert to interact with the underlying core scheduling
technology in domain-specific terms. This is achieved by automatically instantiating an abstract GUI template on top of the second modeling layer. 相似文献

The development of the nitration process in heterogeneous mixtures of benzonitrile and mixed acids of different compositions is followed in a batch stirred isothermal reactor. Preliminary evaluation of the distribution of the chemical species between the organic and acid phases allows mathematical modelling of benzonitrile nitration under heterogeneous conditions to be achieved on the basis of the previously assessed homogeneous nitration kinetics. 相似文献

An architecture for electrically configurable gate arrays 总被引:1,自引:0,他引:1

An architecture for electrically configurable gate arrays using a two-terminal antifuse element is described. The architecture is extensible, and can provide a level of integration comparable to mask-programmable gate arrays. This is accomplished by using a conventional gate array organization with rows of logic modules separated by wiring channels. Each channel contains segmented wiring tracks. The overhead needed to program the antifuses is minimized by an addressing scheme that utilizes the wiring segments, pass transistors between adjacent segments, shared control lines, and serial addressing circuitry at the periphery of the array. This circuitry can also be used to test the device prior to programming and observe internal nodes after programming. By providing sufficient wiring tracks segmented into carefully chosen lengths and a logic module with a high degree of symmetry, fully automated placement and routing is facilitated 相似文献

Arnheim hypothesized that as children develop they invent increasingly more structural equivalents. Thus, in their drawings children should increase the number and complexity of both representational concepts (e.g., object edges) and associated object shape features (e.g., line junctions). The authors tested whether a framework derived from this hypothesis could describe the progression of raised-line (haptic) drawings made during nine months by three children born totally blind. With no drawing tuition, these children made drawings of objects such as cars, human figures, trees, and flowers. Later drawings had more features than earlier ones and could be mapped onto more complex, predicted representational concepts, supporting Arnheim's conjecture. Because this applied even if children did not have visible models, the increase in features occurred not because children learned to copy ornate pictures (or increasingly more conventions) but because they developed increasingly complex concepts to describe the many features of objects. Our findings and reframing of structural equivalences suggest a view of children's drawing as expression of "everyday aesthetics" through the development of personal creativity.

Given a relation ?? ? ?? × ?? on a set ?? of objects and a set ?? of attributes, the AOC-poset (Attribute/Object Concept poset), is the partial order defined on the “introducers” of objects and attributes in the corresponding concept lattice. In this paper, we present Hermes, a simple and efficient algorithm for building an AOC-poset which runs in O(m i n{n m, n α }), where n is the number of objects plus the number of attributes, m is the size of the relation, and n α is the time required to perform matrix multiplication (currently α = 2.376). Finally, we compare the runtime of Hermes with the runtime of other algorithms computing the AOC-poset: Ares, Ceres and Pluton. We characterize the cases where each algorithm is the more relevant. 相似文献

Computing functional dependencies from a relation is an important database topic, with many applications in database management, reverse engineering and query optimization. Whereas it has been deeply investigated in those fields, strong links exist with the mathematical framework of Formal Concept Analysis. Considering the discovery of functional dependencies, it is indeed known that a relation can be expressed as the binary relation of a formal context, whose implications are equivalent to those dependencies. However, this leads to a new data representation that is quadratic in the number of objects w.r.t. the original data. Here, we present an alternative avoiding such a data representation and show how to characterize functional dependencies using the formalism of pattern structures, an extension of classical FCA to handle complex data. We also show how another class of dependencies can be characterized with that framework, namely, degenerated multivalued dependencies. Finally, we discuss and compare the performances of our new approach in a series of experiments on classical benchmark datasets. 相似文献
