Summary
Disaster-resilient wireless networks can be built using unmanned aerial vehicles (UAVs). A new tool optimizes UAV backhaul networks, balancing access and backhaul capacity for reliable communication.
Area of Science:
- Engineering
- Computer Science
- Telecommunications
Background:
- Wireless networks are crucial but vulnerable to disasters, disrupting communication.
- Unmanned aerial vehicles (UAVs) offer a solution for rapidly deployable, temporary networks.
Purpose of the Study:
- To develop a capacity-deployment tool for designing and evaluating UAV-aided backhaul networks.
- To analyze backhaul network performance under realistic urban conditions.
Main Methods:
- A novel tool was created to simultaneously allocate resources for ground user access and UAV backhaul.
- Evaluated three backhaul scenarios (3.5 GHz, 3.5 GHz with carrier aggregation, 60 GHz) with different UAV types.
- Simulated performance in Ghent, Belgium, considering backhaul capacity and power constraints.
Main Results:
- An optimal UAV flight height of 80m was identified to balance access and backhaul needs.
- Achieving full network coverage proved challenging.
- Network performance was analyzed concerning UAV flight height and user demand.
Conclusions:
- UAV-aided networks offer a viable solution for disaster resilience in wireless communications.
- Optimizing UAV flight height and resource allocation is key to network performance.
- Further research into advanced mechanisms is needed to enhance UAV network capacity within realistic constraints.

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

01:27Emerging Adulthood
640
Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

02:04Covalently Linked Protein Regulators
8.7K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.

02:18Network Covalent Solids
16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

01:19X-linked Traits
58.3K
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.

Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...
