Consider two newsvendors: (i) they compete satisfying substitutable demands searching Nash equilibrium or (ii) one is the leader deciding first, the other responds optimally playing a Stackelberg game. The leader profits more than she does in (i). We present conditions under which the leader's profit does not improve from (i) to (ii). 相似文献

Equilibrium dialysis of metal-serum albumin (Ⅱ)——Allosteric effect in Ni(Ⅱ)-serum albumin systems 总被引:1,自引:0,他引:1
Detailed studies were carried out on equilibrium dialysis of the binding of Ni2++ ion to human scrum albumin (HSA) and bovine serum albumin (BSA).The successive stability constants were obtained by the Icfisi squares fitting.The eight binding sites found for both Ni(Ⅱ)-HSA and Ni(Ⅱ)-BSA systems can be divided into two different sets; and for both systems,there exist two identical prior binding sites where the bound Ni2+ ions can he con sidered as allosteric effectors,which induce the allosteric effect in accordance with the model proposed by Moeod et al As indicated by allosteric parameters,the ability of R-state to bind Ni2+ ions is ca 100 times as much as that of T state,and the conformation of HSA is markedly tenser than that of BSA. 相似文献

In this paper we study price competition for two types of location-price models in which facility locations are set up and
price decisions have to be made in order to maximise profit. We discuss the existence and determination of equilibrium prices
in a general location space when facilities have different production costs. It is assumed that each price is bounded from
below and demand for a single homogeneous product is price-inelastic. When facilities set mill prices, a price equilibrium
rarely exists and necessary conditions for existence are obtained. In particular, when the location space is a tree network,
we give a characterisation of the locations for which a unique equilibrium exists for two competitors. With spatial price
discrimination, though equilibrium prices might not exist, it is shown that ε-equilibrium prices always exist for any locations
of the facilities. A characterisation of ε-equilibrium is also given. Then the location-price problem is reduced to a location
problem. A comparison of results with the two types of price determination is also presented.

The equilibrium of sorption of KNO3 from aqueous solutions by a granular polymer containing immobilized dibenzo-18-crown-6 was studied. The thermodynamic characteristics
for sorption of an electrolyte by a crown-containing polymer were determined. It was shown that the adsorption sites are energetically
equivalent in the range of compositions studied.

This paper discusses an extension of the currently available theory of noncooperative dynamic games to game models whose state equations are of order higher than one. In a discrete-time framework, it first elucidates the reasons why the theory developed for first-order systems is not applicable to higher-order systems, and then presents a general procedure to obtain an informationally unique Nash equilibrium solution in the presence of random disturbances. A numerical example solved in the paper illustrates the general approach.Dedicated to G.

The influence of pre-equilibrium emission on (n, p) reaction cross-sections at 14.8 MeV has been studied. Cross-sections for (n, p) reactions have been measured by the activation technique at 14.8 .1; 0.5 MeV neutron energy. The experimental cross-section
values have been compared with the calculated values at 14.8 MeV with and without considering the pre-equilibrium emission.
Equilibrium calculations have been performed according to the statistical model of Hauser and Feshbach while the hybrid model
has been used to include the pre-equilibrium contribution. Pre-equilibrium emission has been considered only in the first
emission step. The comparison of experimental and calculated values clearly indicates the presence of pre-equilibrium emission. 相似文献

In this paper, we will introduce the generalized operator equilibrium problem and generalized operator quasi-equilibrium problem which generalize the operator equilibrium problem due to Kazmi and Raouf [K.R. Kazmi, A. Raouf, A class of operator equilibrium problems, J. Math. Anal. Appl. 308 (2005) 554-564] into multi-valued and quasi-equilibrium problems. Using a Fan-Browder type fixed point theorem in [S. Park, Foundations of the KKM theory via coincidences of composites of upper semicontinuous maps, J. Korean Math. Soc. 31 (1994) 493-519] and an existence theorem of equilibrium for 1-person game in [X.-P. Ding, W.K. Kim, K.-K. Tan, Equilibria of non-compact generalized games with L∗-majorized preferences, J. Math. Anal. Appl. 164 (1992) 508-517] as basic tools, we prove new existence theorems on generalized operator equilibrium problem and generalized operator quasi-equilibrium problem which includes operator equilibrium problems. 相似文献
