The robot will find and neutralize a traitor colleague

29.06.2023

Researchers at the University of Lausanne have developed a groundbreaking algorithm that can disable robotic actions that could disrupt a team's functioning.

Based on the principle of voting, the algorithm prevents possible failures and errors that can lead to undesirable consequences.

Colleague robots perform a variety of tasks, including rescue and construction, by working together. However, some robots can go over to the side of opponents and oppose other members of the group. These situations can lead to a disruption in the effectiveness of the entire team.

An algorithm developed by scientists proposes a voting mechanism that allows collaborating robots to identify and isolate Byzantine robots. This ensures that the team's work remains consistent and prevents the negative influence of traitorous elements.

The researchers are confident in the effectiveness of the algorithm and its ability to neutralize Byzantine robots in various scenarios. In addition, the tests carried out confirmed that the algorithm is resistant to possible errors and random changes in the behavior of conventional robots, which makes it a reliable tool for ensuring the safety and efficiency of the work of fellow robots.

The term "Byzantine robot" comes from the "Byzantine generals problem", which was first introduced in 1982 in an article by Leslie Lamport. This problem arises in distributed systems, where participants, in this case robots, must reach agreement in making decisions, despite possible failures or attacks from some participants.

In the context of robotics, Byzantine robot refers to a robot that deliberately or accidentally misinforms or acts incorrectly within a distributed robotic system. This may include passing on incorrect information, performing incorrect actions, or even actively interfering with the work of other robots on the team. The Byzantine robot is an element that violates the integrity and reliability of the system, creating potential problems and risks for the team of accomplice robots.

The development of algorithms and mechanisms capable of detecting and neutralizing Byzantine robots is an important task in the field of robotics and security of distributed robotic systems.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Immunity saves tattoos 11.03.2018

Our skin is regularly updated, and this applies not only to the epidermis, in which the replacement of old cells with new ones takes only a month, but also to a deeper layer - the dermis. But if the skin is renewed, then why do tattoos stay on it for so long?

To understand why the tattoo pigment doesn't fade away as the skin renews itself, researchers from the French Institute INSERM tattooed the tails of mice and observed how the skin cells behave.

When ink gets into the skin during tattooing, it attracts the attention of macrophage immune cells. Their function is to eat everything alien and potentially dangerous. Pigment particles are also perceived by macrophages as something that should neutralize, and absorb them. But the macrophages themselves don't live very long either. It would seem that after the death of the macrophage, the paint that was in it can now come off along with the dying particles of the skin.

However, this "orphan" paint is picked up by other macrophages that have replaced the dead ones. In the experiment, mice a few weeks after the tattoo were given an injection that killed all macrophages in the skin (without harm to the health of animals) - however, the tattoo remained in place: new cells came to where it was and absorbed the paint that was found in the intercellular space of the dermis .

In another experiment, a piece of tattooed skin was transplanted from one mouse to another, and after six weeks, all the dye that was in the transplanted skin passed from the cells of one mouse (donor mouse) to the cells of another. According to the authors of the work, immune macrophages are the only cells in the skin that can absorb tattoo pigment, and tattoos remain on the skin for so long precisely because of this ability, and also because macrophages pick up the paint left after dead cells.

It is known that many people would like to reduce their tattoos, but now it takes quite a long time to erase a tattoo. It is possible that the process can be accelerated if macrophages on the tattooed area of ​​the skin are purposefully destroyed for a while - of course, doing this in such a way as not to damage the immune system as a whole.
