Design Example: Resistive Touchscreen01:14

Design Example: Resistive Touchscreen

522
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

Steps in Outbreak Investigation01:18

Steps in Outbreak Investigation

284
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Overview Of Cell Separation And Isolation01:20

Overview Of Cell Separation And Isolation

6.6K
Cell separation was first achieved in 1964 by S. H. Seal, who separated large tumor cells from the smaller blood cells using filtration. Two years later, Pohl and Hawk performed experiments on how cells respond differently to a nonuniform electric field based on the cell type. Such observations were the inception of cell separation methods, which allow isolating a single cell type from a heterogeneous sample.

Contact-dependent Signaling01:19

Contact-dependent Signaling

45.7K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

In animal cells, gap junctions are formed...

Area of Science:

  • Digital epidemiology
  • Public health technology
  • Mobile application security

Background:

  • Manual contact tracing is resource-intensive and inefficient for large-scale disease outbreaks.
  • Digital contact tracing has become crucial in managing the COVID-19 pandemic.
  • Official Android contact tracing applications from European countries were examined.

Purpose of the Study:

  • To conduct a thorough security and privacy analysis of European Android contact tracing apps.
  • To identify potential vulnerabilities and misconfigurations in these applications.
  • To assess the overall security posture of digital tools used for infectious disease control.

Main Methods:

  • Static analysis included examination of permissions, API calls, external URLs, trackers, manifest, shared software, and taint analysis.
  • Dynamic analysis involved collecting data on Java classes and network traffic.
  • Dynamic instrumentation was employed for in-depth app scrutiny.

Main Results:

  • The study identified several weaknesses, vulnerabilities, and misconfigurations across the analyzed apps.
  • While apps were generally well-engineered, specific security flaws were detected.
  • Potential risks to user security and privacy were highlighted.

Conclusions:

  • European Android contact tracing apps, despite being well-engineered, present security and privacy risks.
  • Vulnerabilities and misconfigurations necessitate further attention to protect users.
  • Continuous security assessment is vital for public health digital tools.
