IP3/DAG Signaling Pathway01:11

IP3/DAG Signaling Pathway

13.0K
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...

Role-Based Identity01:21

Role-Based Identity

38
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...

The Availability Heuristic01:08

The Availability Heuristic

6.7K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Short-distance Transport of Resources02:12

Short-distance Transport of Resources

16.8K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Issues And Trends In Healthcare Delivery System

5.9K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Applications of IR Spectroscopy: Overview01:11

Applications of IR Spectroscopy: Overview

1.6K
The non-destructive nature and ability to provide valuable chemical information make IR spectroscopy a versatile technique with broad applications in various scientific and industrial fields. IR spectroscopy is commonly used to identify and characterize organic and inorganic compounds. It provides information about the functional groups present in a molecule and the bonding between atoms. This helps in the structural elucidation of compounds during organic synthesis, pharmaceutical research,...

Area of Science:

  • Computer Science
  • Network Security
  • Internet of Things

Background:

  • The proliferation of Internet of Things (IoT) devices necessitates efficient and secure resource discovery mechanisms.
  • Current discovery models often lack attribute-based access control, leading to privacy concerns and potential security vulnerabilities.
  • Decentralized approaches are crucial to manage the scale and complexity of IoT networks.

Purpose of the Study:

  • To propose Attred, a novel decentralized resource discovery model for IoT networks.
  • To enable secure and location-aware resource discovery based on client and resource attributes.
  • To enhance privacy and reduce reliance on central authorities in IoT resource management.

Main Methods:

  • Implementation of a decentralized model using a Region-based Distributed Hash Table (RDHT).
  • Integration of Attribute-Based Encryption (ABE) to enforce attribute-driven discovery policies.
  • Utilization of secret sharing for secure and distributed computation of resource registration and key generation.

Main Results:

  • Attred facilitates secure and location-aware resource discovery based on inherent client attributes.
  • The model effectively distributes workload for key generation and resource registration, minimizing central authority risks.
  • Performance analysis confirms significant reduction in computation cost through distributed computation while maintaining security.

Conclusions:

  • Attred provides an efficient and secure solution for resource discovery in IoT environments.
  • The proposed model ensures discovery correctness, soundness, resource privacy, and client privacy.
  • Decentralization and attribute-based access control are key to scalable and secure IoT resource management.
