This paper analyzes optimal contracts in a linear hidden-action model with normally distributed returns possessing two moments that are governed jointly by two agents who have negative exponential utilities. They can observe and verify each others’ effort levels and draft enforceable side-contracts on effort levels and realized returns. Standard constraints, resulting in incentive contracts, fa...

The synthetic glucocorticoid dexamethasone markedly decreases the invasiveness of HT-1080 human fibrosarcoma cells. We show here that dexamethasone treatment of HT-1080 cell aggregates more than doubles their cohesivity from 3.9 to 9.7 dyne/cm. Western blot analysis shows a corresponding increase in cadherin expression. This was accompanied by an increase in the rate of calcium-dependent aggreg...

Blockchain-based distributed computing platforms enable the trusted execution of computation—defined in the form of smart contracts—without trusted agents. Smart contracts are envisioned to have a variety of applications, ranging from financial to IoT asset tracking. Unfortunately, the development of smart contracts has proven to be extremely error prone. In practice, contracts are riddled with...

The capability to reallocate items|e.g. tasks, securities, bandwidth slices, Mega Watt hours of electricity, and collectibles|is a key feature in automated negotiation. Especially when agents have preferences over combinations of items, this is highly nontrivial. Marginal cost based reallocation leads to an anytime algorithm where every agent's payo increases monotonically over time. Di erent c...

buy-back contracts in the upstream oil and gas projects of iran, has experienced the third generation of this kind of contracts since its inception on 1373 (1994) when the oil and gas industry of iran opend its petroleum market to the foreign investment. these contracts have since been subject to the various critieques raised by international oil companies, foreign investors, or petroleum exper...

the analyze of petroleum contracts demonstrate that in respect to the intensity of the cooperation between the state company and oil companies, we could find the different evaluative categories of the contracts on upstream oil industry.historically, the first generation of the petroleum contracts was the concession agreement in which the transferring of ownership was the base. the license agree...

time sharing contracts are a new type of contracts relating to immovable property created in response to modern life necessities. the main feature of this type of contract is that the ownership of property is transferred to the buyer for a limited period of the year. unlike traditional sale contracts in which the buyer acquires the complete and continuous ownership of the property purchased, in...

The in vitro cytocompatibility of silicate (Laponite clay) cross-linked poly(ethylene oxide) (PEO) nanocomposite films using MC3T3-E1 mouse preosteoblast cells was investigated while cell adhesion, spreading, proliferation and mineralization were assessed as a function of film composition. By combining the advantageous characteristics of PEO polymer (hydrophilic, prevents protein and cell adhes...
