Development of the ehive Digital Health App: Protocol for a Centralized Research Platform.

Background: The increasing use of smartphones, wearables, and connected devices has enabled the increasing application of digital technologies for research. Remote digital study platforms comprise a patient-interfacing digital application that enables multimodal data collection from a mobile app and connected sources. They offer an opportunity to recruit at scale, acquire data longitudinally at a high frequency, and engage study participants at any time of the day in any place.

[Digital health: elderly use of electronic services.].

The vulnerability of the elderly was especially exacerbated during the CODID-19 pandemic and after, when strict restrictive measures on freedom of movement were introduced and many services began to be provided remotely.

Porous PZT Films: How Can We Tune Electrical Properties?

Porous ferroelectric lead zirconate titanate (PZT) films are a promising material for various electronic applications. This study focuses on understanding how the structure-directing agent, polyvinylpyrrolidone, can alter the structure and electrical properties of porous PZT films prepared through chemical solution deposition. Films with various porosities of up to ~40 vol.

Econ-assessments.org: Automated Assessment of Economics Skills.

Standard assessments can give instructors reliable objective measures of student skills at the beginning and end of a term. We describe seven standard assessments that we have developed for commonly taught economics courses, and introduce a new website, econ-assessments.org, that allows instructors worldwide to set up any of our assessments for their students.
