Communication01:03

Communication

8.0K
Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

Communication

9.9K
Sharing information, concepts, and emotions to foster mutual understanding is communication. The sender, recipient, and transaction must be considered in this manner. The sender is the person who shares the message, the recipient is the person who receives and understands the message, and the transaction is the method used to deliver the message and the variables that affect the communication's context and surroundings. The nurse-client connection is built on therapeutic communication.

Contact-dependent Signaling01:19

Contact-dependent Signaling

40.2K
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.

Carrier-Mediated Transport01:06

Carrier-Mediated Transport

1.6K
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...

Group Polarization01:01

Group Polarization

31.3K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Non-ohmic Devices00:51

Non-ohmic Devices

1.5K
In most substances, the current flow is proportional to the voltage applied to it. A simple relationship between the values of current, voltage, and resistance is known as Ohm's law. Nonohmic devices do not exhibit a linear relationship between voltage and current. One such device is the semiconducting circuit element known as a diode. A diode is a circuit device that allows current flow in only one direction.
Consider a simple circuit consisting of a battery, a diode, and a resistor. A...

Background:

  • Smart embedded objects are key to the Internet of Things (IoT).
  • Current solutions for managing groups of smart objects and their resources lack reliability, flexibility, and manageability.

Main Methods:

  • Developed a novel solution building upon the Constrained Application Protocol (CoAP).
  • Implemented a system to create, validate, use, and delete groups of CoAP resources.
  • Introduced a profile-based approach for detailed group manipulation.
  • Quantitatively analyzed performance and compared it against multicast-based CoAP group communication.

Main Results:

  • The implemented solution successfully covers the complete group life-cycle.
  • The proposed method enhances reliability and flexibility in managing groups of smart objects.
  • A trade-off was observed, with increased communication overhead compared to multicast-based approaches.

Conclusions:

  • The novel solution effectively addresses limitations in managing groups of smart objects in IoT environments.
  • The use of profiles offers advanced control over group behavior.
  • The approach provides a viable alternative to existing group communication methods, balancing performance with enhanced functionality.
