We study the two-band degenerate Hubbard model using the fluctuation exchange approximation (FLEX) and compare the results with quantum Monte Carlo (QMC) calculations. Both the self-consistent and the non-self-consistent versions of the FLEX scheme are investigated. We find that, unlike in the one-band case, in the multiband case, good agreement with the quantum Monte Carlo results is obtained ...

Demand-driven spectrum allocation can drastically improve performance for WiFi access points struggling under increasing user demands. While their frequency agility makes cognitive radios ideal for this challenge, performing adaptive spectrum allocation is a complex and difficult process. In this work, we propose FLEX, an efficient spectrum allocation architecture that efficiently adapts to dyn...

Micron sizes solder metallurgical joints have been applied in a thin film application of anisotropic conductive film and benefited three general advantages, such as lower joint resistance, higher power handling capability, and reliability, when compared with pressure based contact of metal conductor balls. Recently, flex-on-board interconnection has become more and more popular for mobile elect...

In the purely theoretical approach of pavement design, percentage fatigue cracking is related to damage in a probabilistic manner according to the Miner’s law. Two methods that are currently widely in use are based on assumptions of damage distribution. One method assumes fatigue damage being normally distributed, while the other one assumes fatigue damage being lognormally distributed. Since m...

This paper seeks to understand the impact of the Medicare Rural Hospital Flexibility (Flex) Program on hospital choice and consumer welfare for rural residents. The Flex Program created a new class of hospital, the Critical Access Hospital (CAH), which receives more generous Medicare reimbursements in return for limits on capacity and length of stay. We find that conversion to CAH status result...

FLEX is a new scalable \locality aware" solution for achieving both load balancing and eecient memory usage on a cluster of machines hosting several web sites 1, 2]. FLEX allocates the sites to diierent machines in the cluster based on their traac characteristics. Here, we propose a set of new methods and algorithms (Simple+, Advanced, and Advanced+) to improve the allocation of the web sites t...

This study was conducted by the Flex Monitoring Team with funding from the federal Office of Rural Health Policy (PHS Grant No. U27RH01080) Introduction This report focuses on evidence-based pneumonia Quality Improvement (QI) programs and strategies that are applicable to critical access hospitals (CAHS). The Flex Monitoring Team prepared this report as part of a larger project, whose purpose i...
