there is much interest in finding short presentations for the finite simple groups. indeed it has been suggested that all these groups are efficient in a technical sense. in previous papers we produced nice efficient presentations for all except one of the simple groups with order less than one million. here we show that all simple groups with order between $1$ million and $5$ ...
Economic choice entails assigning values to the available options and is impaired by lesions to the orbitofrontal cortex (OFC). Recent results show that some neurons in the OFC encode the values that monkeys (Macaca mulatta) assign to different goods when they choose between them. A broad and fundamental question is how this neuronal representation of value depends on the behavioral context. He...
Most models used in climate economics so far are full-employment models. In Germany, as in other countries suffering from persistent unemployment, climate policy can only be successful if it is embedded in an economic policy that generates additional jobs at a large scale. To investigate the possibility for such embedding, a long-term model of the German economy is needed. lagom sim is such a m...
BACKGROUND: Phyllodes tumors are biphasic fibroepithelial neoplasms of the breast. While the surgical management of these relatively uncommon tumors has been addressed in the literature, few reports have commented on the surgical approach to tumors greater than ten centimeters in diameter – the giant phyllodes tumor. CASE REPORT: We report a case of a 45-year-old woman who presented with a larg...
Since the 1950’s, prestressed concrete beams have become a factor in almost one third of all new bridge construction in the United States. In Michigan, prestressed concrete was introduced in 1954 and the first prestressed concrete side-by-side box-beam bridge was built in 1955. Pontis data indicates 2,054 side-by-side prestressed concrete box-beam bridges in Michigan; 236 are part of the Nation...

Insecticide-treated nets (ITNs) for malaria control are widespread but coverage remains inadequate. We developed a Bayesian model using data from 102 national surveys, triangulated against delivery data and distribution reports, to generate year-by-year estimates of four ITN coverage indicators. We explored the impact of two potential 'inefficiencies': uneven net distribution among households a...
We report the results of a high-statistics search for H dibaryon production in inclusive Υ(1S) and Υ(2S) decays. No indication of an H dibaryon with a mass near the M(H)=2m(Λ) threshold is seen in either the H→Λpπ(-) or ΛΛ decay channels and 90% confidence level branching-fraction upper limits are set that are between one and two orders of magnitude below the measured branching fractions for in...
