Advanced technologies such as drones, intelligent algorithms and androids have grave implications for human existence. With the purpose of exploring their basis doing so, paper proposes a framework investigating complex relationship between devices practices language-mediated cognition. Specifically, it centers on importance typically neglected intermediate layer culture which not only drives b...

We propose an approach for tuning a gain spectrum of semiconductor lasers under temperature fluctuations, where the heat-induced effect is dynamically compensated using a mechanical stressing. By stressing GaAs/Ge/Si microbeams, emission wavelength tuning is experimentally demonstrated for the overlying GaAs layers as a proof-of-concept, and the results are followed by theoretical calculations....

These lectures provide an overview of the theory of accretion disks with application to bright sources containing black holes. I focus on the fundamental physics of these flows, stressing modern developments and outstanding questions wherever possible. After a review of standard Shakura-Sunyaev based models and their problems and uncertainties, I describe the basic principles that determine the...

How can stakeholder theory contribute to opportunity theory? We suggest that affords appropriate theoretical lenses for grounding the opportunity-actualization perspective more firmly within real-world constraints of business venturing. Actualization departs from a strong focus on entrepreneurial agency conceptualize how pre-existing environmental conditions determine what action achieve. expla...

The Bianchi Stress Questionnaire was built and validated to assess the stress level of hospital nurses. The questionnaire is selfapplicable, composed of 51 items, and divided into six subscales, each receiving a score that ranges from 1 to 7. Subscales are composed of activities that involve nursing care and management. The use of this questionnaire highlights the most stressing subscale for ei...

OBJECTIVE Atrial septal defect (ASD) occluders are permanent implants in paediatric cardiology which serve as mechanical shields until complete overgrowth and incorporation of the occluding device by autologous tissue has occurred. Thereafter, the foreign body material making up the device is dispensable and bears potential long-term adverse effects. Rapid, firm and complete incorporation into ...

Powder bed fusion is an emerging additive manufacturing technique capable of producing complex formed metallic structures, which are not possible to manufacture with conventional manufacturing. These benefits design freedom and manufacturability often exploited in aerospace together topology optimization produce components low mass high stiffness. However, monolithic structures lead weakly damp...
