Due to the rapid penetration of Internet Things (IoT) into human life, illegal access IoT resources (e.g., data and actuators) has greatly threatened our safety. Access control, which specifies who (i.e., subjects) can what objects) under conditions, been recognized as an effective solution address this issue. To cope with distributed trust-less nature systems, we propose a decentralized trustworthy Capability-Based Control (CapBAC) scheme by using Ethereum smart contract technology. In...
The large-scale and trustless nature of the Internet Things (IoT) calls for distributed trustworthy access control schemes to prevent unauthorized resource access. This paper proposes a Capability-Based Access Control (CapBAC) scheme by applying emerging Ethereum blockchain technology. uses smart contracts, i.e., executable codes residing in blockchain, store manage capability tokens, special data structures that maintain allowed actions user (i.e., subject) on certain object). To provide...
Abstract Regarding crystalline film growth on large lattice-mismatched substrates, there are two primary modes by which thin films grow a crystal surface or interface. They Volmer-Weber (VW: island formation) mode and Stranski-Krastanov (SK: layer-plus-island) mode. Since both end up in the formation of three-dimensional (3D) islands, fabrication single substrates has been challenging. Here, we demonstrate another mode, where buffer layer consisting 3D islands initially forms relaxed...
Natural product-derived carbon dots (CDs) have been widely studied as environmentally friendly materials for various applications, such bioimaging and sensors, catalysts, solar cells. Electroluminescence (EL) is one of the most desirable characteristic CDs optical devices in display lighting applications. EL with possess a layered structure, which serve middle emission layer sandwiched by transport layers electrodes. Electrons holes are injected into active CD an external bias voltage give...
In this position paper, we introduce an instance of interlanguage clones in a multilingual Web application system and then discuss research challenges on the detection analysis.
The Angkor monuments were built between the 9th and 15th centuries using gray to yellowish brown sandstone, red greywacke, which are petrologically classified as feldspathic arenite, quartz lithic wacke, respectively. Gray sandstone was generally used in all of monument temples. Red main building material Banteay Srei temple but also occasionally mixed with temples after late Bayon period. Greywacke five sanctuaries atop Ta Keo for statues Linga-Yoni pedestals. To distinguish these...
Heteroepitaxial growth of single-crystalline zinc oxide (ZnO) films on a c-plane sapphire substrate is an important technology for electronics and optoelectronic devices. Recently, the inverted Stranski–Krastanov (SK) mode has been demonstrated, it realized heteroepitaxial ZnO by sputtering. In this mode, 10 nm-thick buffer layer consisting three-dimensional islands (3D layers) initially forms relaxes strain, then, two-dimensional film (2D layer) grows involving small strain. To clarify...
Front Cover: In article number 1900240 by Shinjiro Machida and co-workers, photo temperature-responsive poly(2-isopropyl-2-oxazoline)s with a spiropyran group in the side-chain are synthesized, their stimuli-responsive properties aqueous solution evaluated. The introduction of groups causes marked decrease cloud point even when pendant contain zwitterionic merocyanine form. photoinduced phase transition is demonstrated at an optimum temperature.
Defects in spacecraft software may result loss of life and serious economic damage. To avoid such consequences, the development process incorporates code review activity. A conducted by a third-party organization independently team can effectively identify defects software. However, activity is difficult for reviewers, because they need to understand entire structure within limited time without prior knowledge. In this study, we propose tool visualize inter-module dataflow source systems....
Abstract Poly(2‐isopropyl‐2‐oxazoline)s with varied loading of the spiropyran side‐chain are synthesized, and their photochemical thermosensitive properties characterized in aqueous solution. The absorption spectrum sample solution (0.1 wt%) indicates that 7.8 mol% pendant groups zwitterionic merocyanine form. introduction causes a marked decrease cloud point even when contain samples form is slightly (less than 1 °C) lower bearing group. Moreover, photoinduced phase transition demonstrated...
放射性物質に汚染された廃棄物の熱処理では，含有されるセシウム (Cs) が飛灰へ移行するため，飛灰中 Cs の不溶化が必要である。本研究では，カオリン試薬の熱的変化やアルカリ溶液への Al, Si の溶解特性を調査した。さらに，焼成したカオリン試薬を用い，模擬飛灰中 のジオポリマーによる不溶化処理を行なった。その結果，メタカオリンは焼成パイロフィライトと比較して，アルカリ溶液に溶解しやすく，作製した固化体の 溶出率は低くなった。Si/Al のような材料構成比では，アルミノケイ酸塩の種類や NaOH 濃度による 不溶化への影響の評価は困難であったが，Sidissolved/Aldissolved を用いることで，Cs 不溶化に直接寄与する のバランスの変化が明確になった。本研究より，アルミノケイ酸塩のアルカリ溶液への溶解特性は，ジオポリマーによるCs不溶化性能を制御する重要な指標となることが示唆された。

We propose a new framework of collective decision-making, which takes conflicts interest among the voters and voting alternatives (e.g., committee members/referees applicants/contestants for some competition) into account. extend notion social welfare function to include structures introduce two accountability axioms: Impartiality No-Power-Game property. is voter behavior, property discourages applicants from increasing interested voters. Although many extensions scoring rules satisfy these...
