Various studies have highlighted older persons' problems in potentially failing to keep pace with developments in information technology and the latest technologies that prevent physical and social loss. In contrast to such studies that treat users as static and technology as changing, it's important to understand the use of technology can change over time. For example, older persons have used tec

We have experimentally studied the conditions for acoustic particle focusing inside aqueous droplets in two-phase-systems, and confirmed our findings by theoretical analysis. The results show that the acoustic properties of the two fluids have to be matched to achieve strong acoustic resonance and focusing in the system.

We derive an expression for the acoustic force density acting on an inhomogeneous fluid with a continuous spatial variation in density and compressibility. A key prediction of our theory, validated by confocal imaging in an acoustofluidic microchip, is that inhomogeneous fluid configurations can be stabilized in the presence of destabilizing forces due to gravity or acoustic streaming flows.

This abstract reports a novel acoustofluidic method to measure the hematocrit level of a whole blood sample within 20 seconds. The method is substantially faster than conventional centrifugation methods, has no moving parts and can be fully automated and integrated with further unit operations for analysis of blood samples at the point of care [1].

Laser-induced fluorescence for remote imaging of historical monuments is an established technique, which in this work has been used in measurement campaigns at the Coliseum and the Baptistery of San Giovanni in Laterano in Rome, Italy. The results presented here are examples that show that biodeteriogens can be monitored and that. materials can be identified. Also, cleaned and soiled areas on the

Abstract in UndeterminedThe success of the Wii and of the iPhone together with the persisting problem of displaying information on the small screens of mobile devices is currently pushing the development of non-visual interaction channels such as gestures, tactile/haptic interaction and sound. This development presents both potential and risk, since new channels of interaction may result either in

Monitoring a microservice system may bring a lot of benefits to development teams such as early detection of run-time errors and various performance anomalies. In this study, we explore deep learning (DL) solutions for detection of anomalous system's behavior based on collected monitoring data that consists of applications' and systems' performance metrics. The study is conducted in a collaboratio

This chapter gives an overview of key actions by the activist group Gender Relations in New Music, which advocates for increased gender equality and intersectional diversification in contemporary classical music (CCM). The chapter describes this particular group’s activities, which have included creating statistics, organizing events, protesting actions, and connecting interested people in this st

We present a fabrication scheme of contacting arrays of vertically standing nanowires (NW) for LEDs (Duan et al. Nature 409:66–69, 2001), photodetectors (Wang et al. Science (NY) 293:1455–1457, 2001) or solar cell applications (Wallentin et al. Science (NY) 339:1057–1060, 2013). Samples were prepared by depositing Au films using nano-imprint lithography (Ma rtensson et al. Nano Lett 4:699–702, 200

Students’ learning developments of limits were studied in a calculus course. Theiractions, such as problem solving and reasoning, were considered traces of theirmental representations of concepts and were used to describe the developmentsduring a semester. Several students went through the course with a vague conception of limits which in some cases was wrong. A higher awareness about their mental

The paper presents a work in progress which is part of a larger study. Studentslearning analysis was investigated with the aim to find out how their concept images changed from the beginning of an analysis course to a year after the course. Their links between concepts were studied after the year had passed. The influence of the students’ pre-knowledge was durable and sometimes prevented students

We present a microchannel-based adaption of density-gradient centrifugation that allows the instantaneous, precise, and repeatable generation of a 1-dimensional mass-density gradient and determination of single-cell densities with integrated mass-density calibration.
