The paper studies the optimal distribution of business and residential land in a circular city. Once the optimum is characterized, we analyze the effect of changes in commuting costs and externality parameters. We also propose policies like labor subsidies, land taxes and zoning restrictions that can implement the efficient allocation as an equilibrium, or close the gap between the optimal and ...

A trusted quantum relay is introduced to enable quantum key distribution links to form the basic legs in a quantum key distribution network. The idea is based on the well-known intercept/resend eavesdropping. The same scheme can be used to make quantum key distribution between several parties. No entanglement is required.

For applications with large data sets, e.g., video servers, magnetic disks have established themselves as the mass storage device of choice. A technique to increase the storage capacity of disks is zoning. A side-eeect of zoning is that it introduces a disk drive with variable transfer rates. This chapter describes techniques to support a continuous display of constant-bit rate video and audio ...

Oregon's land-use planning program is often cited as an exemplary approach to forest and farmland conservation, but analyses of its effectiveness are limited. This article examines Oregon's land-use planning program using detailed spatial data describing building densities in western Oregon. An empirical model describes changes in building densities on forest and agricultural lands from 1974 to...

This paper examines the effects of environmental zoning policies on lakefront land development, sorting, and economic welfare in a model where agents are heterogeneous in preferences and income. Agents consume lakefront amenities that are endogenous to development and the sorting process yields lakes which differ by amenities and frontage prices. Our findings include the following: i) lakes bec...

Large earthquakes occur in rocks undergoing high-pressure/low-temperature metamorphism during subduction. Rhythmic major-element zoning in garnet is a common product of such metamorphism, and one that must record a fundamental subduction process. We argue that rhythmic major-element zoning in subduction zone garnets from the Franciscan Complex, California, developed in response to growth-dissol...

Self-healing group key distribution is a primitive aimed to achieve robust key distribution in wireless sensor networks (WSNs) over lossy communication channels. However, all the existing self-healing group key distribution schemes in the literature are designed for homogenous WSNs that do not scale. In contract, heterogeneous WSNs have better scalability and performance. We are thus motivated ...

Observation of social and economic trends (falling population in the inner city of Paris, increased commuter flows between the centre and the suburbs, and demand for local ticket prices) has led the Syndicat des Transports Parisiens (STP, the Paris transport authority) to re -examine the ticket price system as it is today. Reform of this system will involve a great many stakeholders in the tran...

Despite the unconditionally secure theory of the Quantum Key Distribution (QKD), several attacks have been successfully implemented against commercial QKD systems. Those systems have exhibited some flaws, as the secret key rate of corresponding protocols remains unaltered, while the eavesdropper obtains the entire secret key. We propose the negative acknowledgment state quantum key distribution...
