Social platforms are currently encountering a set of burning issues: low ad conversion rates, cross-channel free-riding phenomena, lack monetary incentives to retain premium content creators, etc. Direct purchase behaviors between social platform users (e.g., making direct through seller's promotional post) can largely resolve these problems. Therefore, it is imperative study the factors that i...

We consider the pricing problem of a platform that matches heterogeneous agents using match‐contingent fees. Absent prices, on short side such markets capture relatively greater surplus than those long (Ashlagi et al. 2017). Nevertheless we show need not bias its price allocation toward either side. With independently drawn preferences, optimal decisions are independent market size or imbalance...

because of fluctuation in leg tension, pitch motion is very effective fatigue and life safety of leg elements in tension leg structures (tlss). in this paper an exact solution for pitch vibration of a tls interacting with ocean wave is presented. the legs of tlp are considered as elastic springs. the flow is assumed to be irrotational and single-valued velocity potentials are defined. the effec...

Experimentation platforms are essential components of modern large IT companies, as they are used to carry out a large number of randomized experiments daily. On such platforms, the classic assumption of no interference among users—that is, the fact that the outcome of a user does not depend on the treatment assigned to other users—is rarely tenable. Here, we introduce an experimental design st...

Clinicians frequently assess movement performance during a bilateral squat to observe the biomechanical effects of foot orthotic prescription. However, the effects of rearfoot position on bilateral squat kinematics have not been established objectively to date. This study aims to investigate these effects in a population of healthy adults with a pronated foot type. Ten healthy participants with...

Sensor networks are rather challenging to deploy, program, and debug. Current programming languages for these platforms suffer from a significant semantic gap between their specifications and underlying implementations. This fact precludes the development of (type-)safe applications, which would potentially simplify the task of programming and debugging deployed networks. In this paper we defin...
