Efficient visualization of security events in a large agent society

A production market with given preferences, technology and compe tition technology is vulnerable if it admits both perfect competition and monopoly or oligopoly. Under decreasing returns, sunk costs combined with a potential for monopoly profits provide a sufficient basis for vulnerability. A large agent can establish monopoly by installing enough productive capacity. The monopolist deters entry by threatening to oversupply the market. The threat is credible if the future discount rate is low enough and if enough small players enter the market in the absence of punishment. Financial institutions can capture vulnerable markets for profit, reducing competition, efficiency and equity.

Large Agent

Biophysical procedures have been used to determine the size and structure of the biologically active agent responsible for the transmission, through milk, of mouse mammary adenocarcinoma. Filtration of milk from RIII high-breast-cancer mice through gradocol membranes with decreasing pore sizes indicated that a minimum of activity passed through intermediate pore sizes (100 to 160 mµ). Filtrates through smaller pores were significantly active. Milk treated with small doses of deuteron irradiation produced more tumors than the control, unirradiated milk; larger doses indicated a particle size much less than 100 mµ. Free diffusion experiments indicated that the activity was associated with particles of two different sizes. Altogether the data denoted the presence of a large agent about 100 mµ in diameter and a small agent 20 to 30 mµ in diameter or possibly smaller. Furthermore, the presence in the milk of an inhibitor 40 to 60 mµ is indicated by the results of all three approaches. The complex nature of the milk agent disclosed by the physical measurements agrees with the picture of one of the structures revealed by electron microscopy as well as with seemingly conflicting measurements reported in the literature. The large agent defined by these indirect methods corresponds to the whole particle seen in the electron microscope and the small agent corresponds to its internal core or nucleoid. It is suggested that the nucleoid is essentially a nucleic acid which may, in the absence of the "inhibitor," retain its activity after being stripped of its outer membrane or sac.
