When Vertical Is Horizontal: How Vertical Mergers Lead To Increases In “Effective Concentration”, Serge Moresi, Steven C. Salop

Georgetown Law Faculty Publications and Other Works

This article explains the inherent loss of an indirect competitor and reduction in competition when a vertical merger raises input foreclosure concerns. We then calculate a measure of the effective increase in the HHI measure of concentration for the downstream market, and we refer to this “proxy” measure as the “dHHI.” We derive the dHHI measure by comparing the pricing incentives and associated upward pricing pressure (“UPP”) involved in two alternative types of acquisitions: (i) vertical mergers that raise unilateral input foreclosure concerns (and the associated vertical GUPPI measures), and (ii) horizontal acquisitions of partial ownership interests among …

Short-Term Fatigue Damage Of Tethers Of Long-Span Floating Cable Supported Bridges Under Harsh Waves, Deokhee Won, Keesei Lee, Young-Jong Kang, Seungjun Kim

Journal of Marine Science and Technology–Taiwan

A floating bridge can be effectively used for sea-crossing in deep water. Because the superstructure of the bridge is supported by floating substructures with pontoons, the conventional fixed piers, towers, foundations, and piles are not required. Instead, a rational mooring system can be used to strictly maintain the target position of the floating substructures against environmental loads, including winds, waves, and currents. Recently, long-span cable-supported bridges with floating towers were investigated and found to overcome the limitations of conventional cable-supported bridges, when used as sea-crossing infrastructure. To design the moorings for very large floating structures, the structural safety should be …

BACKGROUND: Unlike β(1)- and β(2)-adrenergic receptors (ARs), β(3)-AR stimulation inhibits cardiac contractility and relaxation. In the failing left ventricular (LV) myocardium, β(3)-ARs are upregulated, and can be maladaptive in the setting of decompensation by contributing to LV dysfunction. This study examined the effects of intravenous (i.v.) infusions of the β(3)-AR antagonist APD418 on cardiovascular function and safety in dogs with systolic heart failure (HF).

METHODS AND RESULTS: Three separate studies were performed in 21 dogs with coronary microembolization-induced HF (LV ejection fraction [LVEF] of approximately 35%). Studies 1 and 2 (n = 7 dogs each) were APD418 dose escalation studies …

Study On Underwater Navigation For Underwater Track Vehicle, Dae-Hyeong Ji, Hyeung-Sik Choi, Sang-Ki Jeong, Hyun-Joon Cho, Ji-Hyeong Lee, Wen-Hsiang Hsieh

Journal of Marine Science and Technology–Taiwan

In this study, an underwater navigation algorithm was developed to apply a navigation system to an underwater track vehicle (UTV). Generally, a Doppler velocity log (DVL) is used to obtain the velocity information of underwater vehicles. However, a DVL cannot be used in a UTV owing to vehicle vibration and limited sensing distance. Hence, dead reckoning navigation is typically used, which results in severe errors in altitude and position values over long periods of operation. To address these problems, in this study, we developed a new underwater navigation system for a UTV using navigation sensors comprising an inertial navigation system, …
