EFFECT OF PHYTASE SUPPLEMENTATION TO DIETS FOR WEANLING PIGS ON THE UTILIZATION OF PHOSPHORUS AND CALCIUM
Four experiments were conducted with weanling pigs to determine the effect of phytase supplementation to four diet types on the apparent total tract digestibility and retention of P and Ca. Phytase was supplemented at rates of 0, 500, and 1000FTU/kg to the four diets. A 20% crude protein (CP) corn-soybean meal diet was used in Exp. 1; a 20% CP wheat-soybean meal diet in Exp. 2; a 20% CP wheat-soybean meal-canola meal diet in Exp. 3; and a 19% CP barley-peas-canola meal diet in Exp. 4. Six barrows were used in each experiment and fed the basal and phytase-supplemented diets according to a repeated 3´3 Latin square design. Each experimental period comprised 14 days. The piglets were fed at 08:00 and 20:00 daily equal amounts of each meal at a daily rate of at least 2.4 times the maintnance requirement for metabolizable energy. Feces and urine were collected from 08:00 on day 8 until 08:00 on day 12 of each experimental period. The results show that phytase supplementation, even to diets supplemented with inorganic P, increases the utilization of P and decreases the excretion in feces. The response of phytase on the utilization of Ca varies with diet composition and is dependent on the dietary Ca content. Phytase supplementation at a rate of 1000 compared to 500FTU/kg diet did not further improve the utilization of P and Ca.

Uncertainty Propagation in Multi-Disciplinary Design Optimization of Undersea Vehicles
In this paper the development of statistical metamodels and statistical fast running models is presented first. They are utilized for propagating uncertainties in a multi-discipline design optimization process. Two main types of uncertainty can be considered in this manner: uncertainty due to variability in design variables or in random parameters; uncertainty due to the utilization of metamodels instead of the actual simulation models during the optimization process. The value of the new developments and their engagement in multi-discipline design optimization is demonstrated through a case study. An underwater vehicle is designed under four different disciplines, namely, noise radiation, self-noise due to TBL excitation, dynamic response due to propulsion impact loads, and response to an underwater detonation. The case study also demonstrates the value of the multi-discipline design optimization in identifying a system level optimum, and it emphasizes the importance of including uncertainties in the design optimization process.

Occurrence and Control of Psilothrips indicus Bhatti
Adults and nymphs of Psilothrips indicus Bhatti are harmful to Chinese wolfberry. The insect bodies are densely covered on leaf back under severe condi- tion to suck sap. The damaged leaves are longitudinally reflexed, resulting in early defoliation, atrophy of fruit shape or even fruit dropping. P. ind/cus can be con- trolled by agricultural, physical, chemical control methods.

Towards Staining Independent Segmentation of Glomerulus from Histopathological Images of Kidney
This paper introduces a detection-based framework to segment glomeruli from digital scanning image of light microscopic slide of renal biopsy specimens. The proposed method aims to better use the precise localization ability of Faster R-CNN and powerful segmentation ability of U-Net. We use a detector to localize the glomeruli from whole slide image to make the segmentation only focus on the most relevant area of the image. We explored the ef-fectiveness of the network depth on its localization and segmentation ability in glomerular classification, and then propose to use the classification net-work with enhanced ability of localization and segmentation to construct and initialize a segmentation network. We also propose a weakly supervised training strategy to train the segmentation network by taking advantage of the unique morphology of the glomerulus. Both strong initialization and weakly supervised training are used to resolve the problem of insufficient and inaccurate data annotations and enhance the adaptability of the segmentation network. Experimental results demonstrate that the proposed framework is effective and robust Footnotes * Change the author's email and fixed the incorrect institute name.

A radical sonic departure
W hen Thurston Moore's Trees Outside the Academy was re- leased a few months ago, many listeners did a double-take. Was this real- ly the Sonic Youth kingpin? How could Moore possibly do an album without putting blood in the music? Did someone put the wrong vinyl in the album sleeve . _

The challenges of sub-20nm shallow trench isolation etching
Unlike neutral species, ions are less susceptible to shadowing effects due to their acceleration by the sheath electric field, which leads to more directionality. Consequently, intra-cell depth loading can be reduced if the silicon trench formation were dominated by ions (Cl+ or Br+) instead of radicals. Ion dependent etching can be realized by increasing ion energy or ion density. To increase ion energy, one can elevate the bias power or lower the bias frequency.
