In a second-price auction with costly bidding, bidders can deter others from participating by publicly pre-committing to bid. Such “bid deterrence” increases total welfare when the reserve price is given, but allows the seller to increase expected revenue when the seller can pre-commit to a reserve price. JEL Codes: D44.
In this paper we prove a recent conjecture [Robnik M and Salasnich L 1997 J. Phys. A: Math. Gen. 3

Objective: In order to increase the level of performance of impact skills in martial arts, based on two main physical principles of work,-energy and impulse-momentum in analyzing these skills was done. Methods: The search of articles was carried out in specialized databases and then 31 related articles selected based on entry and exit criteria were analyzed. Results: In this study, it was spe...
The studied gabbroic rocks have exposures around Darreh-Bid salt dome. The rocks are located about 130 km south of Shahrekord (Chaharmahal and Bakhtiari Province). The studied area is a part of Zagros structural zone. Mineral chemistry studies were done on clinopyroxenes in the gabbroic rocks of the Darreh- Bid salt dome. The clinopyroxenes are diopsid and augite and are plotted in low pressur...
M q ðxÞ 1⁄4 x T q ðxÞ x T q ðxÞ: (5) Since Jþi is a leading-twist operator, it is clear that such a simple partonic interpretation should exist. However, Ji, Xiong, and Yuan misleadingly interpret Jþi as the transverse angular momentum operator. Indeed, in light-front quantization, the role of time is taken by xþ, so that Jþi is the light-front transverse boost operator. In terms of the more co...
A classical theory is developed which calculates the momentum transfer rate constant between an ion and a non-polar molecule. The model takes into consideration the effect of diffraction outside the capture limit on the rate constants. The theory is used to calculate momentum transfer rate constant for Cl- with trans-dichloroethylene and para-difluorobenzene. Theoretical results ...
Bridge abutments are usually located in the floodplain zone of rivers where velocity and shear stress are not uniformly distributed. The influence of channel geometry and lateral momentum transfer in compound flow field on the scouring phenomenon has not been fully investigated and understood yet. The impact of lateral momentum transfer on the local scour at abutments terminating in the floodpl...
