The accumulation of contaminating materials on the rotor blades of a gas turbine flowmeter is a condition of concern to the manufacturers, since it can lead to loss of calibration. Over time, a deposit of tar and heavy oil mixed with sand and dust can build up on the rotor blades, which causes the meter factor to change from its original value of calibration. A novel neural-network technique is...

A renewed interest in the role of complement in the pathogenesis of glomerular diseases has improved our understanding of their basic, underlying physiology. All 3 complement pathways-classical, lectin, and alternative-have been implicated in glomerular lesions both rare (e.g., dense deposit disease) and common (e.g., IgA nephropathy). Here we review the basic function of these pathways and hig...

The martian Residual South Polar Cap (RSPC) is a 1–10 m thick deposit of permanent CO 2 ice perched on the much larger H 2 O ice cap. The CO 2 ice is dissected into mesas by erosional landforms that can be broadly classified as (i) quasi-circular pits, (ii) heart-shaped pits, (iii) linear troughs, and (iv) moats. We use HiRISE (25–50 cm/px) images taken at a cadence of days to months to track m...

It has been recognized that Classification trees (CART) are unstable; a small perturbation in the input variables or a fresh sample can lead to a very different classification tree. Some approaches exist that try to correct this instability. However, their benefits can, at present, be appreciated only qualitatively. A similarity measure between two classification trees is introduced that can me...

The goal of exploration geophysics is to infer the nature of buried structure and, in particular, generate drill targets that lead to a mineral deposit discovery or reserve delineation. As a profession, we aim to turn geophysical data into geological information. Most geophysical techniques enable inferences to be made from airborne, ground-based or bore-hole data through a deterministic proces...

Results of arthroscopic management of chronic, recalcitrant calcific tendinopathy of the shoulder in 28 patients were evaluated. Twenty-six patients (average age, 44 years) were ultimately enrolled in the study. Postoperative radiographs were performed to determine the amount of calcium deposit removal. Radiographic examination 2 months after surgery was performed to evaluate further deposit ch...

We analyze a banking system in which the class of feasible deposit contracts, or mechanisms, is broad. The mechanisms must satisfy a sequential service constraint, but partial or full suspension of convertibility is allowed. Consumers must be willing to deposit, ex ante. We show, by examples, that under the socalled “optimal contract,” the post-deposit game can have a run equilibrium. Given a p...

This paper proposes a new approach to determining the supply chain (SC) design for a product comprising different subassemblies. There might be multiple suppliers that could supply the same components as well as many manufacturers that could assemble the product. Each of these options is differentiated by its lead time and cost. Given all the possible options the configuration problem is to sel...

In the recent recession and current economic recovery, policymakers have supported asset prices in the U.S. treasury and mortgage markets, expecting that improvement in the balance sheet of banks will lead to more commercial lending. In general, we document that increases in housing prices in a bank’s deposit base lead banks to decrease commercial lending. Further, we find that a one-standard d...
