37. PROFITABILITY INDEX. INTERNAL RATE OF RETURN

RATE OF RETURN Index of profitability (PI - Profitability index) is calculated by the formula

where Investments - initial investment; CFt - net cash flow of month t; N - duration of the project, months; r - monthly discount rate.

The PI indicator shows the relative profitability of the project. It determines the amount of profit per unit of invested funds. A prerequisite for the implementation of the project: the profitability index must be greater than one.

Internal rate of return (IRR-Internal rate of return) is determined from the following ratio:

where Investments - initial investment; OFt - net cash flow of month t; N - duration of the project, months; IRR - internal rate of return.

The project is considered acceptable if the calculated IRR value is not lower than the required rate of return, which is determined by the company's investment policy. At IRR equal to the discount rate, NPV is equal to zero.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Mystery of human brain evolution solved 03.09.2012

The rapid increase in the size and cognitive capabilities of the human brain (in the process of evolution) turned out to be due to repeated copying of the same gene.

Everyone knows that the size and cognitive abilities of the brain make a person a special representative of the animal world of our planet. However, so far no one has been able to unravel the riddle of the rapid evolutionary "spurt" that has awarded us with such an amazing mental tool. The results of a study conducted by scientists at the University of Colorado indicate that the key to the puzzle is a large number of copies of the gene encoding the protein domain DUF1220 (from the English. Domain of unknown function - a domain with an unknown function).

This gene has over 270 copies in the human genome. At the same time, the number of copies in the genome of animals is the greater, the greater the degree of its similarity with humans. For example, the DUF1220 domain is encrypted 125 times in the chimpanzee genome, 99 times in the gorilla genome, 30 times in the monkey genome, and only one copy is present in the mouse genome.

The results of the study showed that the more copies of the gene encoding the DUF1220 domain are contained in the genome, the larger the brain size of the organism. This pattern applies not only to different species, but also to individual representatives of the human population. Moreover, the analysis of the genomes of patients with microcephaly - a congenital disease characterized by an abnormally small brain size - and its opposite - macrocephaly - showed that even with pathological abnormalities, the brain size directly depends on the number of copies of the gene encoding the DUF1220 domain.

This discovery provides specialists with a new approach to diagnosing abnormalities associated with brain size. From a broader point of view, it opens up new avenues for studying the human brain and the incredible increase in its size and capacity that has occurred within a very short period from an evolutionary perspective.
