An upper bound on the total inelastic cross-section as a function of the total cross-section

Recently Andr\'e Martin has proved a rigorous upper bound on the inelastic cross-section $\sigma_{inel}$ at high energy which is one-fourth of the known Froissart-Martin-Lukaszuk upper bound on $\sigma_{tot}$. Here we obtain an upper bound on $\sigma_{inel}$ in terms of $\sigma_{tot}$ and show that the Martin bound on $\sigma_{inel}$ is improved significantly with this added information.Comment: 4 page

On zeros of Martin-L\"of random Brownian motion

We investigate the sample path properties of Martin-L\"of random Brownian motion. We show (1) that many classical results which are known to hold almost surely hold for every Martin-L\"of random Brownian path, (2) that the effective dimension of zeroes of a Martin-L\"of random Brownian path must be at least 1/2, and conversely that every real with effective dimension greater than 1/2 must be a zero of some Martin-L\"of random Brownian path, and (3) we will demonstrate a new proof that the solution to the Dirichlet problem in the plane is computable

Documentation of a Collection of Archaeological Materials from the Millsey Williamson Site (41RK3), A Historic Nadaco Caddo Settlement

The Millsey Williamson site (41RK3) is a well known historic 18th century Nadaco Caddo site on Martin Creek in Rusk County, Texas. It is one of a number of 18th and early 19th century Kinsloe phase sites in the middle Sabine River basin apparently affiliated with the Nadaco Caddo settlement of the region. An unknown number of historic Nadaco Caddo burials have been excavated at the site over the years, especially along the western part of the terrace landform above Martin Creek, now marked by the Martin Lake shoreline. There has been intensive collecting activities at Millsey Williamson since Martin Lake was built more than 30 years ago. The collection we document here came from the shoreline in the general area of the other Nadaco Caddo burials reported from Millsey Williamson

Too far ahead of its time: Barclays, Burroughs and real-time banking

The historiography of computing has until now considered real-time computing in banking as predicated on the possibilities of networked ATMs in the 1970s. This article reveals a different story. It exposes the failed bid by Barclays and Burroughs to make real time a reality for British banking in the 1960s
