Feed accounts for 60 to 70% of broiler production costs . Thus, improvement in feed efficiency is needed. Ileal digestibility (ID) and total-tract amino acid (AA) utilization are the parameter used to evaluate feed ingredients . However, ID of AA can be affected, for example, by gut inflammation as a result of a coccidial vaccine challenge. Adedokun et al. (2014) showed significantly high ileal...
Studies of past sea-level markers are commonly used to unveil the tectonic history and seismic behavior of subduction zones. We present new evidence on vertical motions of the Hellenic subduction zone as resulting from a suite of Late Pleistocene - Holocene shorelines in western Crete (Greece). Shoreline ages obtained by AMS radiocarbon dating of seashells, together with the reappraisal of shor...
Dam safety is considerably affected by seepage, and uplift pressure a key indicator of dam seepage. Thus, making accurate predictions trends can improve hazard forecasting. In this study, convolutional neural network, (CNN)-gated recurrent (GRU)-based prediction model was developed, which included the CNN model’s feature extractability GRU learnability for time series correlation data. Then, pe...
[1] We introduce a quantitative model of global mantle convection that reconstructs the detailed motion of a warm mantle upwelling over the last 30 Ma towards the interior of the southwestern USA from observed present-day mantle heterogeneity. The onset and evolution of uplift in the central Basin and Range province and Colorado Plateau during this time is determined by tracking the topographic...
[1] We image the crustal architecture of the Musgrave Province with petrophysically constrained forward models of new potential field data. These models image divergent shallow-dipping crustal scale thrusts that, at depth, link with an axial zone defined by steeper, lithospheric scale transpressional shear zones. They also show that to permit a near-surface density distribution that is consiste...
We introduce Score As You Lift (SAYL), a novel Statistical Relational Learning (SRL) algorithm, and apply it to an important task in the diagnosis of breast cancer. SAYL combines SRL with the marketing concept of uplift modeling, uses the area under the uplift curve to direct clause construction and final theory evaluation, integrates rule learning and probability assignment, and conditions the...
[1] Motions of three hundred and sixty Global Positioning System (GPS) sites in Canada and the United States yield a detailed image of the vertical and horizontal velocity fields within the nominally stable interior of the North American plate. By far the strongest signal is the effect of glacial isostatic adjustment (GIA) due to ice mass unloading during deglaciation. Vertical velocities show ...
The Peruvian Andes is a prime example of highly-elevated topography generated by oceanic plate subduction. As a result, several studies have been made to further understand the formation of the Andean Mountain Range, but as indicated by previous studies (Schildgen et al, 2007), researchers are still unable to ascertain the of the magnitude of the uplift solely based on structural history due to...
[1] We describe a procedure to measure coseismic change of shallow coastal bathymetry using multispectral imagery. This technique is applied to HYPERION hyperspectral images acquired along the shallow coast of the North Andaman Islands to estimate the uplift induced by the Mw 9.15, 26 December 2004, earthquake. Attenuation coefficient of the particularly clear coastal waters is estimated from t...
In this work we assess the most recent estimates of glacial isostatic adjustment (GIA) for Antarctica, including those from both forward and inverse methods. The assessment is based on a comparison of the estimated uplift rates with a set of elastic-corrected GPS vertical velocities. These have been observed from an extensive GPS network and computed using data over the period 2009-2014. We fin...
