AGRICULTURE-TO-INSTREAM AND URBAN WATER TRANSFERS IN THE CENTRAL VALLEY OF CALIFORNIA: AN ECONOMIC REALITY CHECK

More than two million acre-feet (MAF) of water transfers from agriculture to urban and instream are discussed and debated in California. We use a regional agricultural production and water transfer model to evaluate potential third party impacts of transferring one MAF of water from the Central Valley of California. A range of impacts is estimated under three different scenarios. Our base scenario shows that the adverse economic impacts in the area of origin include a $170 net personal income loss for each acre-foot of water transferred, and 8 job losses for each thousand acre-feet of water transferred.Resource /Energy Economics and Policy,

On-Line Portfolio Selection with Moving Average Reversion

On-line portfolio selection has attracted increasing interests in machine learning and AI communities recently. Empirical evidences show that stock's high and low prices are temporary and stock price relatives are likely to follow the mean reversion phenomenon. While the existing mean reversion strategies are shown to achieve good empirical performance on many real datasets, they often make the single-period mean reversion assumption, which is not always satisfied in some real datasets, leading to poor performance when the assumption does not hold. To overcome the limitation, this article proposes a multiple-period mean reversion, or so-called Moving Average Reversion (MAR), and a new on-line portfolio selection strategy named "On-Line Moving Average Reversion" (OLMAR), which exploits MAR by applying powerful online learning techniques. From our empirical results, we found that OLMAR can overcome the drawback of existing mean reversion algorithms and achieve significantly better results, especially on the datasets where the existing mean reversion algorithms failed. In addition to superior trading performance, OLMAR also runs extremely fast, further supporting its practical applicability to a wide range of applications.Comment: ICML201

Improved Measurement of B(sub 22) of Macromolecules in a Flow Cell

An improved apparatus has been invented for use in determining the osmotic second virial coefficient of macromolecules in solution. In a typical intended application, the macromolecules would be, more specifically, protein molecules, and the protein solution would be pumped through a flow cell to investigate the physical and chemical conditions that affect crystallization of the protein in question. Some background information is prerequisite to a meaningful description of the novel aspects of this apparatus. A method of determining B22 from simultaneous measurements of the static transmittance (taken as an indication of concentration) and static scattering of light from the same location in a flowing protein solution was published in 2004. The apparatus used to implement the method at that time included a dual-detector flow cell, which had two drawbacks: a) The amount of protein required for analysis of each solution condition was of the order of a milligram - far too large a quantity for a high-throughput analysis system, for which microgram or even nanogram quantities of protein per analysis are desirable. b) The design of flow cell was such that two light sources were used to probe different regions of the flowing solution. Consequently, the apparatus did not afford simultaneous measurements at the same location in the solution and, hence, did not guarantee an accurate determination of B22

Methyl 2-[2-((Z)-{1-trans-[2-(4-fluoro-3-methyl­phen­yl)-2-methyl­cyclo­prop­yl]ethyl­idene}amino­oxymeth­yl)phen­yl]-2-[(E)-methoxy­imino]­acetate

The title compound, C24H27FN2O4, is an important inter­mediate in the synthesis of fungicidal strobilurin-type compounds. In the crystal structure, the oxime bond attached to the cyclo­propane ring adopts a Z configuration, while the oxime bond attached to the benzene ring adopts an E configuration. The fluoro­methyl­phenyl group adopts a trans configuration with respect to the remainder of the mol­ecule, and its mean plane forms a dihedral angle of 56.1 (1)° with the plane of the cyclo­propane ring

Robotic dismembered pyeloplasty in a horseshoe kidney after failed endopyelotomy.

We report our experience performing a robot-assisted dismembered pyeloplasty on a patient with a ureteropelvic junction obstruction in a horseshoe kidney and a prior history of endopyelotomy. We provide 18-month follow-up demonstrating that robotic pyeloplasty is a reasonable second treatment option for patients with horseshoe kidneys with failed prior endourological management
