Summary The aim of this paper is to give a survey on several well-known compromise values in cooperative game theory and its applications.
Special attention is paid to the τ-value for TU-games, the Raiffa-Kalai-Smorodinsky solution for bargaining problems, and
the compromise value for NTU-games. 相似文献

Transition probabilities in the odd-odd nucleus146Eu are measured. A recent determination of the lifetime of the 115.6 keV level has indicated a strong retardation of the 115.6 keVM1 transition. In contrast, the present results areT 1/2(230.3)≦165 ps,T 1/2(115.6)≦160 ps. TheE2 cross-over transitions of 269.5 and 230.3 keV were not found in the Ge(Li) gamma spectrum. All results are in agreement with the single particle model. 相似文献

Effect of salt gradients on the separation of dilute mixtures of proteins by ion-exchange in simulated moving beds 总被引:1,自引:0,他引:1

Salt gradients can improve the efficiency during fractionation of proteins by ion-exchange in simulated moving beds (SMBs). The gradients are formed using feed and desorbent solutions of different salt concentrations. The thus introduced regions of high and low affinity may reduce eluent consumption and resin inventory compared to isocratic SMB systems. This paper describes a procedure for the selection of the flow-rate ratios that enables successful fractionation of a dilute binary mixture of proteins in a salt gradient. The procedure is based on the so-called "triangle theory" and can be used both for upward gradients (where salt is predominantly transported by the liquid) and downward gradients (where salt is predominantly transported by the sorbent). The procedure is verified by experiments. 相似文献

The broadening of annihilation line was studied with a Ge detector. The annihilation line was deconvoluted taking into account the instrumental resolution of 1.08 keV. The Pf in several metals are found. The contribution of core electrons to annihilation is deduced. 相似文献

A new class of hexameric Ln12‐containing 60‐tungstogermanates, [Na(H2O)6?Eu12(OH)12(H2O)18Ge2(GeW10O38)6]39? ( Eu12 ), [Na(H2O)6?Gd12(OH)6(H2O)24Ge(GeW10O38)6]37? ( Gd12 ), and [(H2O)6?Dy12(H2O)24(GeW10O38)6]36? ( Dy12 ), comprising six di‐Ln‐embedded {β(4,11)‐GeW10} subunits was prepared by reaction of [α‐GeW9O34]10? with LnIII ions in weakly acidic (pH 5) aqueous medium. Depending on the size of the LnIII ion, the assemblies feature selective capture of two (for Eu12 ), one (for Gd12 ), or zero (for Dy12 ) extra GeIV ions. The selective encapsulation of a cationic sodium hexaaqua complex [Na(H2O)6]+ was observed for Eu12 and Gd12 , whereas Dy12 incorporates a neutral, distorted‐octahedral (H2O)6 cluster. The three compounds were characterized by single‐crystal XRD, ESI‐MS, photoluminescence, and magnetic studies. Dy12 was shown to be a single‐molecule magnet. 相似文献

This paper studies a class of delivery problems associated with the Chinese postman problem and a corresponding class of delivery
games. A delivery problem in this class is determined by a connected graph, a cost function defined on its edges and a special
chosen vertex in that graph which will be referred to as the post office. It is assumed that the edges in the graph are owned
by different individuals and the delivery game is concerned with the allocation of the traveling costs incurred by the server,
who starts at the post office and is expected to traverse all edges in the graph before returning to the post office. A graph
G is called Chinese postman-submodular, or, for short, CP-submodular (CP-totally balanced, CP-balanced, respectively) if for
each delivery problem in which G is the underlying graph the associated delivery game is submodular (totally balanced, balanced, respectively).
For undirected graphs we prove that CP-submodular graphs and CP-totally balanced graphs are weakly cyclic graphs and conversely.
An undirected graph is shown to be CP-balanced if and only if it is a weakly Euler graph. For directed graphs, CP-submodular
graphs can be characterized by directed weakly cyclic graphs. Further, it is proven that any strongly connected directed graph
is CP-balanced. For mixed graphs it is shown that a graph is CP-submodular if and only if it is a mixed weakly cyclic graph.
Finally, we note that undirected, directed and mixed weakly cyclic graphs can be recognized in linear time.

Repartitioning of co-solvents between particles of latex emulsions was investigated by means of a fluorescence method based
on the detection of the amount of co-solvent via the solvatochromic shift of the emission maximum of a fluorescent probe,
copolymerized at a low concentration. Complete repartitioning of co-solvents between particles of latex materials with a low
T
g
(ca. 25 °C) occurred within minutes. For a hydrophilic latex with a T
g
of 68 °C, equilibration was achieved within an hour. Repartitioning was faster for more hydrophobic co-solvents. For a hydrophobic
latex of similar T
g
, co-solvent repartitioning took place on the same time scale, but complete equilibration was not reached. Possibly, there
is an additional slow component in the repartitioning, or the prolonged presence of co-solvent causes a structural change
in the latex particles that affects the outcome of the experiment. 相似文献

We provide a representation for the Müntz orthogonal polynomials as a real integral. This allows us to establish a general result on their asymptotic behavior within the interval of orthogonality. This is the first time that such asymptotics have been obtained for general Müntz exponents {λ n }. We consider some special cases, particularly when the exponents satisfy the asymptotic relation $\lim_{n\rightarrow\infty}\frac{n}{\lambda_n}=\rho $ for some constant ρ>0. 相似文献
