Competitive newsvendor problems with the same Nash and Stackelberg solutions

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).


Pseudoscalar-meson decuplet-baryon coupling constants in light cone QCD
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (American Physical Society (APS), 2009-11-01)
Taking into account the SU(3)(f) breaking effects, the strong coupling constants of the pi, K, and eta mesons with decuplet baryons are calculated within the light cone QCD sum rules method. It is shown that all coupling constants, even in the case of SU(3)(f) breaking, are described in terms of only one universal function. It is shown that for Xi(*0)->Xi(*0)eta, transition violation of SU(3)(f) symmetry is very large and for other channels when SU(3)(f) symmetry is violated, its maximum value constitutes 1...
Quantitative Comparison of Approximate Solution Sets for Multicriteria Optimization Problems with Weighted Tchebycheff Preference Function
Bozkurt, Bilge; Fowler, John W.; Gel, Esma S.; Kim, Bosun; Köksalan, Mustafa Murat; Wallenius, Jyrki (Institute for Operations Research and the Management Sciences (INFORMS), 2010-05-01)
We consider. the problem of evaluating the quality of solution sets generated by heuristics for multiple-objective combinatorial optimization problems. We extend previous research on the integrated preference functional (IPF), which assigns a scalar value to a given discrete set of nondominated points so that the weighted Tchebycheff function can be used as the underlying implicit value function. This extension is useful because modeling the decision maker's value function with the weighted Tchebycheff func...
Calculation of the dielectric constant as a function of temperature near the smectic AC* phase transition in ferroelectric liquid crystals
Kilit, E.; Yurtseven, Hasan Hamit (Informa UK Limited, 2008-01-01)
We calculate here. the dielectric constant E as a function of temperature for the AC* phase transition of a ferroelectric liquid crystal using a mean field model. Using the values of the polarization P and the tilt angle theta, calculated from the mean field model with the P-2 theta(2) coupling for 4-(3-methyl-2-chlorobutanoyloxy)-4'-heptyloxybiphenyl, the dielectric constant E is calculated in the smectic C* phase of this ferroelectric liquid crystal at various temperatures at constant electric fields.
Comment on 'Rockfall avalance deposits associated with normal faulting in the NW of the Cankiri basin: implications for the post-collisional tectonic evolution of the Neo-Tethyan suture zone' by G. Seyitoglu, N. Kazanci, L. Karadenizli, S. Sen, B. Varol, and T. Karabiyikoglu
Kaymakcı, Nuretdin (Wiley, 2003-04-01)
Seyitoglu et al. (2000) described their interpretation, based on a single fault surface and rockfall avalanche deposits previously mapped as a W-vergent thrust klippen above the Neogene successions in the Hancili Basin, that in central Anatolia there was a single extensional basin throughout the Miocene - Early Pliocene. It was later fragmented by a structural high of Neo-Tethyan ophiolitic basement bounded by an E-vergent thrust fault in the east along the western margin of the Cankiri Basin and a west-dip...
Cu-Catalyzed Selective Mono-N-pyridylation: Direct Access to 2-AminoDMAP/Sulfonamides as Bifunctional Organocatalysts
Isik, Murat; Tanyeli, Cihangir (2013-02-15)
Direct and selective mono-N-pyridylation of trans-(R,R)-cyclohexane-1,2-diamine is described here. Facile preparation of a novel chiral 2-aminoDMAP core catalaphore via Cu catalysis has led to the development of various sulfonamide/2-aminoDMAPs as bifunctional acid/base organocatalysts (most in two steps overall), which have been shown to very effectively promote asymmetric conjugate addition of acetylacetone to trans-beta-nitroolefins with good to excellent yields (87-93%) and enantioselectivites (up to 99%).
