Significant technological breakthroughs are often accompanied by articles on the potential impact of these technologies. This article examines blockchain technology and hypothesizes how this ...technology might create substantial changes to how financial services are delivered and by what types of organizations. Banks and brokerage houses providing custodial and record-keeping services may face a change in the value proposition of these services and thus in their price. Blockchain may also expand the definition of what is a tradable security and consequently expand the investable universe.
Once posited as a revolutionary transportation technology, the Segway never took off as some expected because the social acceptance of the technology was not considered in a systematic manner. Using ...a framework for social acceptance of technology borrowed from the literature on renewable energy, we examine how social, economic, and environmental costs of the Segway, along with regulatory issues presented barriers to implementation. High prices, legislative and spatial issues, and a lack of appeal to consumers presented challenges to acceptance. This case study provides a timely reminder of the multifaceted and complex nature of social acceptance that will need to be applied to future innovations, such as autonomous vehicles, to better understand factors that need to be considered for them to be embraced by society.
The Partizansk and Razdolnaya coal basins of Primorye, Far East of Russia, contain diverse early angiosperm fossils (pollen, leaves, and fruits). In this paper, we revise the previous data on early ...angiosperms of this region and summarize the results of our latest research. Age of the plant-bearing deposits was clarified using isotopic U-Th-Pb LA-ICP-MS and U-Pb ID-TIMS methods. Age of the upper part of the Lipovtsy Formation is 118 ± 1.4 Ma, which corresponds to the late Aptian. The early Albian age (109 ± 1 Ma) is assigned to the upper part of the Frentsevka Formation. The diversification of angiosperms in the Early Cretaceous of Primorye region and their systematic affinity are analyzed. Early representatives of Laurales, Ranunculales, Platanaceae, and probable Cercidiphyllaceae are revealed. New combination Pandanites ahnertii (Krysht.) Golovn., comb. nov. is created, and new species Araliaephyllum vittenburgii Golovn. et Volynets, sp. nov. is described. Reconstructions of herbaceous angiosperms from autochthonous locality Bolshoy Kuvshin are proposed.

Naravni kamen so v okolici Ljubljane (Emona) izkoriščali in uporabljali že v rimskem obdobju. Na tem območju so ohranjeni številni kamniti spomeniki iz tistega časa. V članku je predstavljena analiza ...kamnine dveh nagrobnih stel, najdenih na južnem obrobju Ljubljanskega barja, na Ižanskem: nagrobnik za Kviemonija in njegovo družino iz cerkve sv. Janeza Krstnika v Podkraju pri Tomišlju in nagrobnik za Petona z Marofa na Igu (sekundarni najdišči). Na podlagi makroskopskega in mikroskopskega opisa sklepamo, da je spomenik iz Podkraja izklesan iz litiotidnega apnenca spodnjejurske starosti, spomenik z Iga pa iz ooidnega apnenca, ki po starosti sodi v vrhnji del spodnje jure ali v srednjo juro. Oba litološka različka najdemo na južnem obrobju Ljubljanskega barja, pri čemer je najbolj verjetno nahajališče litiotidnega apnenca okolica Podpeči.
Albert W. Frenkel, a pioneer in photosynthesis research, and discoverer of photophosphorylation in photosynthetic bacteria, is remembered here by two of us: Govindjee (historical corner editor of ...photosynthesis research) and Susanna Frenkel (SF; Albert Frenkel’s daughter, who provided most of the family information).

An extraordinarily well-preserved autochthonous angiosperm herbaceous community is described from the Lower Cretaceous deposits of the Frentsevka Formation, southern Primorye, Far East of Russia. The ...locality Bolshoy Kuvshin is situated on the coast of the Ussuri Bay on the Bolshoy Kuvshin Cape near the town of Bolshoy Kamen. The plant-bearing layer was determined to be early - middle Albian in age. The angiosperm assemblage includes six species: Achaenocarpites capitellatus Krassilov et Volynets, Ternaricarpites floribundus Krassilov et Volynets, Jixia pinnatipartita S.X.Guo et G.Sun, Asiatifolium elegans G.Sun, S.X.Guo et Shao L.Zheng and two new undetermined species. The majority of specimens are represented by fragments of branching stems with attached leaves or fruits or by almost complete plants. Two species (Jixia pinnatipartita and Asiatifolium elegans) are also in the angiosperm assemblage from the Chengzihe Formation (eastern Heilongjiang, China). The angiosperm remains are accompanied by the fern Onychiopsis psilotoides which is represented by almost entire young plants. The plant fossils were buried during a single flooding event and remained very close to their original location. They formed a pioneer open herbaceous community, consisting of ferns and angiosperms with a predominance of the latter and adapted to colonize fresh sediments in periodically flooded areas.

An obituary of Woodie Flowers, MIT educator and first robotic collaborator who died October 11 is presented. An ASEE member for more than three decades, Flowers received the Society's President's ...Award in 2015 on behalf of FIRST Robotics, which he served as Distinguished Adviser and Executive Advisory Board member. At MIT, where he was the Pappalardo Professor Emeritus of Mechanical Engineering, Flowers was instrumental in shaping MIT's hands-on approach to engineering design education, the university said in a press release at his death. He developed teaching methods and learning opportunities that culminated in an annual design-and-build competition held for nearly 50 years. Throughout his career, he also designed above-knee prosthetics.
