What feature of behavior when choosing from several alternatives makes people and frogs related?

A study of Tungara frogs revealed an irrational approach of females in choosing a marriage partner, which usually occurs in a lower tone and longer duration of sounds made by the male. If the females were allowed to listen to the sounds of only two males A and B from the speakers, then they always chose male A according to the criteria described above. However, when the sound of male C, which is worse than the first two, was introduced into the experiment, the females in most cases approached speaker B. Similar behavior It is also known in people in the process of making a decision to purchase a product - it is called the "bait effect".

Random interesting fact from the Great Encyclopedia:

Who was the first ruler of England?

We used to think that Britain has always been part of Europe. But it is not. She was not until the XNUMXst century BC. e. The Romans took over Britain and no one in Europe knew anything about it. This is a period in British history about which we know very little.

During the first conquest, the population was called "Britons". They spoke various Celtic dialects, were engaged in agriculture, raised cattle and horses, used iron to make utensils and weapons. Most of them lived in thatched huts in large villages. It was the Romans who built the cities and connected them with roads.

After the departure of the Romans at the beginning of the XNUMXth century, the population remained weakened and fragmented. Hordes of Angles, Saxons and Jutes moved from Denmark and the countries lying on the Rhine. Only after the approval of the Angles, the country received the name "England". Seven large kingdoms formed from small scattered tribes and established themselves in England.

The first settlers, the Britons, were forced into the highlands of Wales and Scotland. These seven kingdoms were called the Heptarchy, or the Union of the Seven States of the Angles and Saxons. In the ninth century they were united under Egbert, who became the first king of England. By this time, England had adopted the Christian faith, which united her with the countries of continental Europe.

Under King Alfred the Great, England was once again forced to fight for independence against the daring invasions of the Danes. This continued until the 24th century, when the country fell under the rule of the Danish king Canute. Later, when the Anglo-Saxon king Edward the Confessor ascended the throne, during his reign the country received a XNUMX-year respite of peace. And after his death, strife flared up again, who would become his successor.

Eventually, in 1066, William, Duke of Normandy, captured England and was later proclaimed its king. The conquest of England by the Normans so changed the life of the country that it can be considered the beginning of a new period in its history.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Intel Tunnel Falls silicon qubit processor 12.06.2023

Intel announced the release of the Tunnel Falls processor, equipped with 12 silicon qubits, and made it available to quantum researchers. Tunnel Falls allows scientists to immediately begin experiments and calculations, instead of wasting time building their own devices. This expands the possibilities of research in the field of the foundations of qubits, quantum dots and the development of new methods for working with multi-qubit devices.

The Tunnel Falls chip is manufactured on 300mm wafers at the Intel D1 factory. This 12-qubit device utilizes Intel's industry-leading transistor manufacturing technologies, including Extreme Ultraviolet Lithography (EUV). Silicon spin qubits encode information (0/1) using the spin (direction of rotation) of the electron. Each qubit is an electronic transistor that can be produced using technology similar to a standard line based on complementary metal-oxide-semiconductor (CMOS).

Through the application of this manufacturing technology, Tunnel Falls achieves high performance, delivering 95% chip yield across the entire wafer, resulting in over 24 working quantum chips per wafer. These chips can be configured from 000 to 4 qubits, which can be isolated or used simultaneously according to the needs of the researchers.

Intel claims that silicon spin qubits are superior to other qubit technologies due to their compatibility with advanced transistors. With dimensions comparable to that of a transistor (approximately 50x50 nm), they are several orders of magnitude smaller than other types of qubits and, according to Nature Electronics, have "the greatest potential for scaling quantum computing."

In an effort to further research into hardware, Intel is actively investigating various parameters such as quantum dot sizes, qubit geometry, and length. In addition, the company is integrating performance testing tools into its chips.

Intel also announced partnerships with several institutions, including the University of Maryland Physical Science Laboratory, the College Park Qubit Collaboratory, the National Quantum Information Science Research Center, and Sandia National Laboratories. These collaborations are aimed at the development of quantum computing. The company plans to make its Intel Quantum Software Development Kit (SDK) version 1.0 available to developers and researchers later this year through the Intel Developer Cloud.

The integration of silicon qubits into the Tunnel Falls processor and their availability to the scientific community is a significant step in the development of quantum computing. This allows researchers to turn to more complex problems, accelerating progress in the field. Quantum computing based on silicon spin qubits is expected to make a significant contribution to science, technology, and solving complex problems that cannot be effectively solved by classical computers.
