One of the main reasons debugging is hard and time consuming is that existing debugging tools do not provide an explanation for the root causes of failures. Additionally, existing techniques either rely on expensive runtime recording or assume existence of a given program input that reliably reproduces the failure, which makes them hard to apply in production scenarios. Consequently, developers...

A major cause of failures in large database management systems (DBMS) is operator/administrator faults. Although most of the complex DBMS available today have comprehensive recovery mechanisms, the effectiveness of these mechanisms is difficult to characterize. On the other hand, the tuning of a large database is very complex and database administrators tend to concentrate on performance tuning...

Colibacillosis is one of an economically significant disease in the poultry industry, especially for meat breed chickens. Recently it has become a serious problem for layer especially when the birds start laying and also at the later stage of laying. In Japan, the productivity of field laying hens improved when the Δcrp avian colibacillosis live vaccine ("Gall N tect CBL") was used. The surviva...

Intraspecific adaptation in Abies sachalinensis was examined using models based on long-term monitoring data gathered during a reciprocal transplant experiment with eight seed source populations and six transplantation sites along an altitudinal gradient. The consequence of local adaptation was evaluated by testing the home-site advantage for upslope and downslope transplants at five ages. The ...

In the absense of frictionless trade, domestic productivity will be a major determinant of prices. Using repeated cross-sections of absolute prices of individual goods across European countries, I find that products of an industry tend to be cheaper in countries with higher productivity in that industry. Similarly, countries with higher productivity in manufacturing have lower prices for produc...

Cowpea is an important grain legume of arid and semiarid regions of Asia and Africa. Productivity of cowpea is low and stagnant. Conventional breeding approaches aimed at improvement of yield per se have not been successful so far in breaking the yield barrier. Manipulation of physiological processes such as photosynthesis is expected to yield positive results. A land race ‘Goa local’ with a ve...

Annual biomass and productivity of Thalassia testudinum were determined during a year at a seagrass bed located in the Parque Nacional Morrocoy, Venezuela. Leaf, rhizome and root biomass were determined monthly, together with short-shoot density, from February 1992 to January 1993, from nine replicated core samples. Productivity was measured using the methodology by Zieman (1974) with minor mod...

The effect of serum on cell growth and monoclonal antibody (MAb) productivity was studied in a repeated fedbatch mode using both free-suspended and immobilized S3H5/gamma2bA2 hybridoma cells. In the suspension culture, serum influenced the cell growth rate but not the specific MAb productivity. The average specific growth rate of the suspension culture in medium containing 10% serum was approxi...

This paper analyzes the absolute convergence of urban electricity productivity in China during 1990–2011, applying Spatial Error Smooth Transition Auto-regression Model, and examines the spatial effect in convergence process. Then it analyzes the stage characteristics of electricity productivity convergence during the process of electricity market reformation and the conditional convergence whi...
