Sample-based XPath Ranking for Web Information Extraction

Web information extraction typically relies on a wrapper, i.e., program code or a configuration that specifies how to extract some information from web pages at a specific website. Manually creating and maintaining wrappers is a cumbersome and error-prone task. It may even be prohibitive as some applications require information extraction from previously unseen websites. This paper approaches the problem of automatic on-the-fly wrapper creation for websites that provide attribute data for objects in a ‘search – search result page – detail page’ setup. The approach is a wrapper induction approach which uses a small and easily obtainable set of sample data for ranking XPaths on their suitability for extracting the wanted attribute data. Experiments show that the automatically generated top-ranked XPaths indeed extract the wanted data. Moreover, it appears that 20 to 25 input samples suffice for finding a suitable XPath for an attribute

Observation of dressed excitonic states in a single quantum dot

We report the observation of dressed states of a quantum dot. The optically excited exciton and biexciton states of the quantum dot are coupled by a strong laser field and the resulting spectral signatures are measured using differential transmission of a probe field. We demonstrate that the anisotropic electron-hole exchange interaction induced splitting between the x- and y-polarized excitonic states can be completely erased by using the AC-Stark effect induced by the coupling field, without causing any appreciable broadening of the spectral lines. We also show that by varying the polarization and strength of a resonant coupling field, we can effectively change the polarization-axis of the quantum dot

Optimizing Soil Nutrient Management to Improve Dry Edible Bean Yield and Protein Quality

Soil nutrient management is of the utmost importance to ensure crop yields are maximized to feed the world’s growing population. Micro and macronutrient deficiencies can be detrimental to plant growth and cause a drastic reduction in yield. Optimization of nutrient management needs extensive research. Nutrients such as nitrogen increase crop yield, even in legumes capable of using a large amount of nitrogen (N) via biological N fixation. Iron (Fe) fertilizers are also crucial for legumes as they are susceptible to Fe deficiency induced chlorosis. Dry edible beans (Phaseolus vulgaris) are leguminous plants and excellent dietary protein sources. Great Northern (GN) beans are a market class of dry edible beans and a major agricultural commodity in Nebraska. Soil nutrient management with N fertilizer can enhance bean production by increasing N uptake, improving protein quantity and quality, and result in a potential economic benefit to bean farmers. Soil nutrient management with Fe fertilizers can combat iron chlorosis and increase bean yield. Thus, this study aims to evaluate and optimize the effects of N treatment on GN bean yield, total protein, soluble protein, digestibility, and intestinal absorption. This study also aims to evaluate the effects of Fe fertilizers on GN bean yield. Results concluded that N treatment at a rate of 140 kg/ha was successful at increasing GN bean yield, total protein, soluble protein, digestibility, and intestinal absorption compared to the control, which had no added N. Results also concluded that Fe fertilizer, regardless of source and application type, had no significant effect on GN bean yield. As the demand for plant-based protein grows, it brings a large market for legume proteins that can be optimized with N management. N management to enhance dry bean yield, protein content, digestibility, and intestinal absorption will benefit the growing population and ensure nutritious plant-based protein sources are available.

Doppler sonography of the uterine and the cubital arteries in normal pregnancies, preeclampsia and intrauterine growth restriction: evidence for a systemic vessel involvement

Aims: The decrease in uterine resistance during normal pregnancy is known to be related to invading trophoblast cells which derive from placental tissue. Uterine and peripheral resistance is elevated in preeclampsia. The aim of the present study was to prospectively examine uterine and peripheral resistance in pregnancies complicated by preeclampsia (PE), fetal intrauterine growth restriction (IUGR) and pregnancy induced hypertension (PIH). Methods: Sixty-seven women with normal pregnancies, 17 with PE, 12 with IUGR underwent Doppler sonographic investigation of the uterine and the cubital arteries. The Pulsatility Index (PI) was calculated for each vessel. Statistical analysis was performed and a P-value < 0.05 was considered significant. Results: Patients with preeclampsia and IUGR showed a significant higher resistance at the placental (mean PI 1.267 and 1.063), nonplacental (mean PI 1.631 and 1.124) and cubital artery (mean PI 3,777 and 3.995) compared to the normal pregnancy group (mean PI 0.678; 0.859 and 2.95 respectively). Mean birth weight in the PE group was 1409 g, in the IUGR group 1649 g and 3419 g in the normal pregnancy group. Conclusions: Pregnancies with IUGR are associated with elevated peripheral resistance in the maternal arterial system as seen in pregnancies with preeclampsia. Our findings encourage to further investigate the maternal vascular system in high risk pregnancies
