Using data collected with the CDF Run II detector, new measurements on bottom production cross-sections are presented. The latest achievements in bottom hadron spectroscopy are discussed. The results are based on a large sample of semileptonic and hadronic decays of bottom states made available by triggers based on the precise CDF tracking system. 1 First Observation of the Baryons Σb and Σ ∗ b...

A 1 yr field study of a long-llved protobranch bivalve, Yoldia notahiljs Yokoyama, in Otsuchi Bay, northeastern Japan, revealed that there was a large seasonal and spatial variation in growth rate and secondary production, and that primary production in the water column and following organlc supply to the bottom were responsible for the vanation. Both shell and soft tissue growth of each of 9 y...

There is high demand for roadway support in coal mines for the swelling soft rocks. As high strength steel sets can be taken as an effective alternative to control large deformation in this type of rocks, based on an original set, three new sets, including a floor beam set, a roof and floor beams set, and a roof and floor beams and braces set, are proposed in this research. In order to examine ...

This paper reviews recent developments in research in nanostructured permanent magnets (hard magnetic materials) with emphasis on bottom-up approaches to fabrication of hard/soft nanocomposite bulk magnets. Theoretical and experimental findings on the effects of soft phase and interface conditions on interphase exchange interactions are given. Synthesis techniques for hard magnetic nanoparticle...

Tropical soft-bottom communities-complex associations of fish and invertebrates living on the smooth Continental Shelf areas between the tropics of Cancer and Capricorn-are both a marine ecologist's dream and a nightmare. They are a dream because their wide variety of species adaptations and lifehistory str.Hegies implies myriads of possible interactions and allows the foundation of large numbe...

Bottom-Up (BU) saliency models do not perform well in complex interactive environments where humans are actively engaged in tasks (e.g., sandwich making and playing the video games). In this paper, we leverage Reinforcement Learning (RL) to highlight task-relevant locations of input frames. We propose a soft attention mechanism combined with the Deep Q-Network (DQN) model to teach an RL agent h...

Through the analysis of benthic foraminifera in soft bottom sediments Laizhou Bay – Yellow River Delta system, this study characterized foraminiferal biotopes and explored possibility obtaining an index ecological quality comparable with other estuarine coastal environments world. Five have been identified their distribution patterns highlight stress from marine-fluvial water mixing pollution. ...

With the global increase of marine protected area (MPA) implementation, need for monitoring and evaluation their effectiveness becomes ever more important. Currently there is a severe lack information about protection effects soft-substrate ecosystems. While many different methods have been established hard-substrate ecosystems, most these minimally invasive prove ineffective soft- bottom habit...
