SUBGROUPS is a free online program at the Bilbao Crystallographic Server (https://www.cryst.ehu.es/). It permits the exploration of all possible symmetries resulting from the distortion of a higher-symmetry parent structure, provided that the relation between the lattices of the distorted and parent structures is known. The program calculates all the subgroups of the parent space group which comply with this relation. The required minimal input is the space-group information of the parent structure and the relation of the unit cell of the distorted or pseudo-symmetric structure with that of the parent structure. Alternatively, the wavevector(s) observed in the diffraction data characterizing the distortion can be introduced. Additional conditions can be added, including filters related to space-group representations. The program provides very detailed information on all the subgroups, including group–subgroup hierarchy graphs. If a Crystallographic Information Framework (CIF) file of the parent high-symmetry structure is uploaded, the program generates CIF files of the parent structure described under each of the chosen lower symmetries. These CIF files may then be used as starting points for the refinement of the distorted structure under these possible symmetries. They can also be used for density functional theory calculations or for any other type of analysis. The power and efficiency of the program are illustrated with a few examples.

Soft X-ray spectroscopy is an important technique for measuring the fundamental properties of materials. However, for measurements of samples in the sub-millimetre range, many experimental setups show limitations. Position drifts on the order of hundreds of micrometres during thermal stabilization of the system can last for hours of expensive beam time. To compensate for drifts, sample tracking and feedback systems must be used. However, in complex sample environments where sample access is very limited, many existing solutions cannot be applied. In this work, we apply a robust computer vision algorithm to automatically track and readjust the sample position in the dozens of micrometres range. Our approach is applied in a complex sample environment, where the sample is in an ultra-high vacuum chamber, surrounded by cooled thermal shields to reach sample temperatures down to 2.5 K and in the center of a superconducting split coil. Our implementation allows sample-position tracking and adjustment in the vertical direction since this is the dimension where drifts occur during sample temperature change in our setup. The approach can be easily extended to 2D. The algorithm enables a factor of ten improvement in the overlap of a series of X-ray absorption spectra in a sample with a vertical size down to 70 µm. This solution can be used in a variety of experimental stations, where optical access is available and sample access by other means is reduced.

Beginning July 1, 2011, computer equipment and televisions will be banned from disposal in North Carolina landfills, under a law passed last year by the General Assembly. Catawba County will provide four one-day electronics recycling collection events in fiscal year 2011-2012, free of charge. All residents of Catawba County will have access to these electronics recycling events, including those who live in the cities and towns in the county.

Welcome to the public release of the latest Institute of Medicine report on the quality of health care in America.

To significantly reduce the tens of thousands of deaths and injuries caused by medical errors every year, health care organizations must adopt information technology systems that are capable of collecting and sharing essential health information on patients and their care, says a new report by the Institute of Medicine of the National Academies.

U.S. colleges and universities should respond with urgency to the current surge in undergraduate enrollments in computer science courses and degree programs, which is straining resources at many institutions, says a new report from the National Academies of Sciences, Engineering, and Medicine.

The National Academy of Engineering announced today that the 2018 Charles Stark Draper Prize for Engineering will be awarded to Bjarne Stroustrup.

Given the current state of quantum computing and the significant challenges that still need to be overcome, it is highly unlikely that a quantum computer that can compromise public-key cryptography – a basis for the security of most of today’s computers and networks – will be built within the next decade, says a new report by the National Academies of Sciences, Engineering, and Medicine.

China has developed OpenKylin, an operating system based on the open-source Linux platform, to reduce its dependence on US technology. OpenKylin 1.0, created by a community of approximately 4,000 developers, has been utilised in various sectors, such as finance, energy, and even in its space program. China's tech industry has prioritised developing an operating system that is not dependent on US technology, and OpenKylin is one of several under development that could replace Microsoft's Windows and Apple's MacOS. Notably, the system provides reliable fundamental software services and ensures security in critical areas such as government affairs and finance.

Looking for ways to perform hard drive recovery? Many things can go wrong while you’re using your device. A power surge can fry it and damage the motherboard, an outage can delete hours of progress if you didn’t save your work, and overuse will cause it to go haywire in the long run. While these won’t cause any permanent damage or loss, a hard drive crash can prevent you from getting your data. What’s worse is that the simplest things like an OS update can cause your system to crash. While there’s nothing you can do to prevent it when
