Carrier-Mediated Transport01:06

Carrier-Mediated Transport

1.5K
Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...

Journal Bearings

1.3K
Journal bearings are mechanical components that support and provide lateral stability to rotating shafts and axles. They are crucial in reducing friction, wear, and vibration in machinery such as engines, turbines, and pumps. The principle behind journal bearings is forming a thin lubricant film between the bearing surface and the rotating shaft, which minimizes direct contact and reduces frictional forces.
To better understand the concept of journal bearings, consider a rope winch with dry or...

Social Loafing01:37

Social Loafing

39.8K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Role-Based Identity01:21

Role-Based Identity

254
Role-based identities are central to understanding how individuals navigate social environments by adopting distinct self-conceptions aligned with various societal roles. These identities are not fixed traits but are constructed through personal actions and the social feedback individuals receive in context-specific interactions. Each social role, such as student, teacher, or friend, carries a set of expectations and norms that influence how people think, feel, and behave within that...

Carrier Transport

1.1K
The generation of electrical current in semiconductors is fundamentally driven by two mechanisms: drift and diffusion. These processes are essential for the functionality and performance of semiconductor-based devices.
Drift Current:
The drift of charge carriers is started by an external electric field (E). Charged particles, such as electrons and holes, experience an acceleration between collisions with lattice atoms. For electrons, this results in a drift velocity (vd) given by:

IP3/DAG Signaling Pathway01:11

IP3/DAG Signaling Pathway

15.6K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the  phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

Area of Science:

  • Computer Science
  • Information Security

Background:

  • The publish/subscribe paradigm enhances IoT service scalability and flexibility by decoupling event producers and consumers.
  • Existing middleware lacks robust mechanisms for preserving IoT service policy privacy, leaving publishers with limited control and subscribers unable to filter events.

Purpose of the Study:

  • To present a novel access control framework designed to preserve IoT service policy privacy within the publish/subscribe communication infrastructure.
  • To address the challenges of policy privacy in large-scale IoT systems.

Main Methods:

  • A two-layer cooperating method is employed, with a data layer for protecting IoT events and an application layer for preserving service policy privacy.
  • The anonymous-set-based principle is utilized for policy embedding, encoding, and matching.
  • The framework was implemented by extending the open-source Apache ActiveMQ broker with a policy-based authorization mechanism.

Main Results:

  • The proposed policy privacy framework is proven to be Chosen-Plaintext Attack secure.
  • Performance evaluation demonstrates that the approach is scalable and introduces only reasonable overheads.

Conclusions:

  • The developed framework effectively preserves IoT service policy privacy in publish/subscribe systems.
  • The integration with Apache ActiveMQ provides a practical and efficient solution for enhancing IoT security.
