Chinese electronics will be assembled in the US

15.12.2012

Chinese manufacturer Lenovo plans to start assembling desktops and laptops in America in the near future. According to industrial sources of the Digitimes resource, the production capacity of the constructed line will be small, but it will be quite enough to fulfill government orders and supplies for the corporate segment.

In line with the trend towards growth in total in-house manufacturing, Lenovo has built five factories in China. However, the company has two plants outside the country - in Mexico and India. In the near future, it is also planned to build factories for the production of computer equipment in Sao Paulo (Brazil) and North Carolina (USA). Sources also do not rule out the possibility of the Chinese company building factories in Germany and Canada. If we talk about own production, then its share in the total volume of manufactured products by Lenovo, according to sources, is expected to increase from 20% in 2012 to 50% in 2013.

According to IDC, Lenovo ranked second in the enterprise desktop market in the third quarter, with a market share of 18,4%. Market leader Hewlett-Packard (HP) has 19,3%. And in the production of laptops for the corporate segment, Lenovo is a confident leader with a market share of 22,3%.

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, ... >>

Neutrino mass measured 14.10.2019

Neutrinos are responsible for many important processes that take place in stars. This particle was previously predicted only theoretically and was introduced to explain the excess energy that comes from the Sun when thermonuclear reactions take place on it. Observing neutrinos directly is very difficult, and for this, scientists carry out ultra-precise measurements in the water column of a huge volume.

Until recently, it was believed that the neutrino is a massless particle, the same as a photon. But the new study not only claims it has mass, it puts limits on its meaning. To do this, scientists used information from various sources, including space and ground-based telescopes that observe the first light of the universe (cosmic microwave background radiation), supernovae, the largest 3D map of galaxies in the universe, particle accelerators and nuclear reactors.

The analysis method they use can be applied to many other types of particles, the scientists say. With the help of it, it was possible to impose restrictions on the mass of all three types of neutrino - electron, muon and tau. Previously, the approximate total mass of all types of neutrinos was established. Now, scientists have gone further and, using the Grace supercomputer, have calculated the maximum mass of one of the types of particles.

It turned out that the mass of the electron neutrino is about a million times less than the electron itself - 1,5x10^-37 kilograms. According to the data, the measurement confidence interval is 95 percent - this is the probability that the real value will be close to the calculated value within the error.

Scientists were able to get this value using a huge array of modern measuring instruments. But even it is not enough to calculate the approximate value of the mass of the other two types of "ghost particles". According to experts, launching new space telescopes and obtaining data from Cherenkov radiation detectors will solve this problem.
