By using the Transfer Matrix Method, explicit formulas for the embedding distribution of doubly hexagonal chain graphs are computed. Dedicated to Ante Graovac 1 Fasciagraphs and rotagraphs An interesting topic that I have learned from Ante Graovac in the 1980’s [1, 2] is that about fasciagraphs and rotagraphs. Such graphs are frequently studied in crystallography and in mathematical chemistry. ...

The achievements of a group frequently depend on the efforts of just a few members but represent a public good benefit to all members. This paper investigates such a situation: the private provision of a public good whose level is determined as the maximum effort made by a group member. Members’ costs of effort are envisioned as either commonly known or privately known. With perfect information...

Very Preliminary and Incomplete. In this paper, I present and estimate a flexible partial equilibrium on-the-job search model with the goal of better understanding wage dynamics. A very recent literature uses search models to understand the dynamics that govern the evolution of wages. This literature tries to solve the problem of lack of structural interpretation that affects univariate models ...

in the presence of uncertainty about what a country can be good at producing, there can be great social value to discovering costs of domestic activities, because such discoveries can be easily imitated. two failures of the laissez – faire outcome are being highlighted: there is too little investment and entrepreneurship ex ante, and too much production diversi-fication ex post. optimal policy ...

Physiological levels of cortisol have been found to blunt neuroendocrine and metabolic responses to subsequent hypoglycemia in humans. The aim of this study was to determine whether cortisol acts directly on the brain to elicit this effect. A total of 41 conscious unrestrained Sprague-Dawley rats were studied during 2-day experiments. Day 1 consisted of two episodes of clamped 2-h hyperinsuline...

We previously determined that both antecedent hypoglycemia and elevated cortisol levels blunt neuroendocrine and metabolic responses to subsequent hypoglycemia in conscious, unrestrained rats. The adrenal steroid dehydroepiandrosterone sulfate (DHEA-S) has been shown in several studies to oppose corticosteroid action. The purpose of this study was to determine if DHEA-S could preserve counterre...

We present a generalization of the standard random-search model of unemployment in which firms hire multiple workers and in which the hiring process is timeconsuming as well as costly. We follow Stole and Zwiebel (1996a, 1996b) and assume that wages are determined by continuous bargaining between the firm and its employees. The model generates a nontrivial dispersion of firm sizes; when firms’ ...

The ex ante real rate of interest is one of the most important concepts in economics and finance. Because the universally-used Fisher theory of interest requires positive ex ante real interest rates, empirical estimates of the ex ante real interest rate derived from the Fisher theory of interest should also be positive. Unfortunately, virtually all estimates of the ex ante real interest rate pu...

− Noise in deep submicron technology combined with the move towards dynamic circuit techniques for higher performance have raised concerns about reliability and energyefficiency of VLSI systems in the deep submicron era. To address this problem, a new noise-tolerant dynamic circuit technique is presented. In addition, the average noise threshold energy (ANTE) and the energy normalized ANTE metr...
