Pre-stack time migration in common source domain without velocity model

We show how to use “complementary priors ” to eliminate the explaining away effects that make inference difficult in densely-connected belief nets that have many hidden layers. Using complementary priors, we derive a fast, greedy algorithm that can learn deep, directed belief networks one layer

introduced a greedy layer-wise unsupervised learning algorithm for Deep Belief Networks (DBN), a generative model with many layers of hidden causal variables. In the context of the above optimization problem, we study this al-gorithm empirically and explore variants to better understand its success

To survive in a world where knowledge is limited, time is pressing, and deep thought is often an unattainable luxury, decision-makers must use bounded rationality. In this precis of Simple heuristics that make us smart, we explore fast and frugal heuristics—simple rules for making decisions

involved in carbohydrate metabolism. The integration of transcriptomic and proteomic datasets generated herein sets the scene for future studies aimed at exploring the potential role(s) that molecules might play at the host– parasite interface and for establishing novel strategies for the treatment

The P2 reverse fault (Figure 1) is a major structure within the Athabasca Basin, Saskatchewan, and is spatially associated with the McArthur River deposit, the world’s largest high-grade uranium mine. The McArthur River deposit is classified as an unconformity-type deposit as the mineralization is located at the unconformity (~500 m depth) between the Athabasca sandstone and basement rocks. The P2 is constrained to graphite-bearing paragneiss of the basement and is refracted within

Deep-submicron CMOS designs have resulted in large leakage energy dissipation in microprocessors. While SRAM cells in onchip cache memories always contribute to this leakage, there is a large variability in active cell usage both within and across applications. This paper explores an integrated

time shifts or phase changes along horizontal to gently dipping reflections. Some of these faults cross the planned open-pit mine at depths of about 300–500 m, and are therefore critical for geotechnical planning. In terms of in-pit and near-mine exploration, the mag-matic layering internal

The Wheeler River Property, host of Denison Mine’s Phoenix uranium deposit, is situated near the southeastern rim of the Athabasca Basin in Northern Saskatchewan (Figure 1). The mineralization drilled to date is estimated to contain from 45 to 90 million pounds U O making Phoenix, even at the lower figure, the sixth largest known individual deposit in the 3 8
