Dynamic Pricing with Parametric Demand Learning and Reference-Price Effects

open access: yesMathematics, 2023
In reality, sellers face challenges in obtaining perfect demand information. Demand is influenced not only by price but also by behavioral factors such as reference effects, which complicate optimal pricing for enterprises.

High-temperature flow behavior and processing map of Inconel 625 alloy under electric heating

open access: yesJournal of Materials Research and Technology
Isothermal tensile tests of Inconel 625 were conducted over a wide temperature range (1173–1373 K) and strain rate domain (0.001–0.1 s−1) using a self-built electric heating tensile testing platform. The flow stress behavior and microstructural evolution

Revisiting two classical results on graph spectra

open access: yes, 2006
Let mu(G) and mu_min(G) be the largest and smallest eigenvalues of the adjacency matricx of a graph G. We refine quantitatively the following two results on graph spectra. (i) if H is a proper subgraph of a connected graph G, then mu(G)>mu(H).

Seiberg-Witten-Floer stable homotopy type of three-manifolds with b_1=0 [PDF]

open access: yes, 2003
Using Furuta's idea of finite dimensional approximation in Seiberg-Witten theory, we refine Seiberg-Witten Floer homology to obtain an invariant of homology 3-spheres which lives in the S^1-equivariant graded suspension category.

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.
