Abstract

The linear submodular bandit problem was proposed to simultaneously address diversified retrieval and online learning in a recommender system. If there is no uncertainty, this problem is equivalent to a submodular maximization problem under a cardinality constraint. However, in some situations, recommendation lists should satisfy additional constraints such as budget constraints, other than a cardinality constraint. Thus, motivated by diversified retrieval considering budget constraints, we introduce a submodular bandit problem under the intersection of $l$ knapsacks and a $k$-system constraint. Here $k$-system constraints form a very general class of constraints including cardinality constraints and the intersection of $k$ matroid constraints. To solve this problem, we propose a non-greedy algorithm that adaptively focuses on a standard or modified upper-confidence bound. We provide a high-probability upper bound of an approximation regret, where the approximation ratio matches that of a fast offline algorithm. Moreover, we perform experiments under various combinations of constraints using a synthetic and two real-world datasets and demonstrate that our proposed methods outperform the existing baselines., accepted at UAI 2020, minor mistakes fixed

8. Measurement of losses and saturated permeability of saturable cores under submicrosecond saturation

Abstract

Two specific methods are introduced for obtaining accurate losses and saturated permeability of saturable cores under submicrosecond saturation. One employs an additional inductor for accurate measurement of the losses. The other minimizes stray inductance for accurate measurement of the saturated permeability. The measured relative permeability of Co-based amorphous cores rapidly drops to nearly 1.0. On the other hand, ferrite cores need a much larger magnetic field than that for Co-based amorphous cores in order to obtain the relative permeability of 1.0.

Abstract

Cs atoms mixed in the CuBr-CsBr-Ne laser system act as energy acceptors of potential energy from the lower laser level the metastable state and enhance laser output and increase laser system efficiency by 30%. These increases occur at a repetition frequency of 35 kHz with a maximum repetition frequency of 55 kHz of achieved for the laser. A decrease in lower copper laser level lifetime accounts for all the increases in the laser system.

Abstract

ストーマ・リハビリテーションと癌告知のかかわりについて,全国主要総合病院の消化器外科・泌尿器科の医局322施設・看護部329施設を対象に,アンケート調査を行った.直接的表現のみでなく婉曲的表現も癌告知とする意見は医師の34%,看護婦の43%に認めた.告知はさまざまな表現,条件で行われており,何らかの形で病状説明はなされていた.告知なしでストーマ造設しても問題なしの意見は72,61%であった.告知の結果ストーマ受容が良好という意見は65,54%,ストーマ・ケアに積極的になったという意見は29,43%に認められた.告知の時期は手術に関係したものが多く,ストーマ・ケアの時期に関係したものは少なく約5%であった.今後癌告知を増やしていく意見は55%,59%と多かった.癌告知により,患者の治療への積極的参加,医療関係者との信頼関係の確立,患者の人格の確保が期待され,ストーマ造設にも癌告知は関無係とはいえず,重要な位置を占めているものと思われる.
