Frontier Sores

(1) An acute phagedenic ulcer, circular in outline with sharp punched out edges usually commencing on the site of some trivial abrasion not necessarily of recent origin. The rapid increase in area and depth of the ulcer was appalling. Within 24 or 48 hours a trivial abrasion might become an ulcer as big as a rupee and with deep fascia exposed in its base. Considerable swelling of surrounding ti...

Frontier Finance

A growing community of long time horizon institutional investors that includes sovereign wealth funds, pension funds, and other beneficiary institutions located in cities outside of the major international financial centers (IFCs), is pushing back against the misaligned incentives and power asymmetries present in the for-profit asset management industry. This expanding group of beneficiary inst...

Frontier Search

How to search the space of programs for a code that solves a given problem? Standard asymptotically optimal Universal Search orders programs by Levin complexity, implementing an exponential trade-off between program length and runtime. Depending on the problem, however, sometimes we may have a good reason to greatly favor short programs over fast ones, or vice versa. Frontier Search is a novel ...

Stochastic Non-Parametric Frontier Analysis

In this paper we develop an approach that synthesizes the best features of the two main methods in the estimation of production efficiency. Specically, our approach first allows for statistical noise, similar to Stochastic frontier analysis, and second, it allows modeling multiple-inputs-multiple-outputs technologies without imposing parametric assumptions on production relationship, similar to...
