In treating diseases with drugs, dosing is critical; too little is ineffective, while too much can be lethal. New research takes a mathematical approach to achieving optimal dosing for various drugs
Researchers have come up with a means of boosting wireless efficiency without increasing interference by mixing full and half duplex radios in base stations. This tunable solution could also allow wireless providers to adjust the mix of cells based on the needs of a region. The research team conducted the first known study to investigate the impact of mixed-cell base stations on spectral efficiency and outages.
New research raises concerns about how easily hackers could take control of flying drones and land or, more drastically, crash them.
A well-insulated home with a high-efficiency air conditioner and programmable thermostat are only as effective as the person using it. A new study shows that people living in green dwellings who don't maximize their technology can lose half of the energy savings available to them.
What happens if people increasingly rely on automated machines to carry out the socially essential work of communicating with one another? Automation of communication raises broad social, economic, and political concerns.
Scientists can now identify the exact location of a single atom in a silicon crystal, a discovery that is key for greater accuracy in the operation of tomorrow's silicon based quantum computers.
Scientists have developed an extremely efficient small-size energy storage, a micro-supercapacitor, which can be integrated directly inside a silicon microcircuit chip.
In a world of digital natives, microfiction and social media in academic settings, Twitter is the ideal tool for regenerating twenty first century writing, according to a recent study.
How many medals will each country win in Rio at this Summer's Olympic Games? Researchers who derived predictions from two different models anticipate that the USA, China, Russia, and the UK will retain their top positions in the medals ranking, but Brazil and Japan are expected to make the biggest gains.
Given the difficult-to-digest subject matter in many STEM classrooms, educators have customarily relied on traditional lecture-based educational methods where they spend class time walking through content and then assign homework problems to supplement that learning. The problem is that this is a difficult way for some students to learn, so educators applying a new approach by flipping their classrooms.
Cheap cameras on drones can be used to measure environmental change which affects billions of people around the world, new research shows.
In the first study of its kind, university researchers say that hackers can discover the identities of people who requested to be delisted under Europe's 'Right to be Forgotten' law. The law allows citizens to petition Internet search providers such as Google to remove search results linked to personal information that is negative or defamatory.
There is a gap in the theory explaining what is happening at the macroscopic scale, in the realm of our everyday lives, and at the quantum level, at microscopic scale. Scientists now say that the assumption that quantum particles move because they follow a precise trajectory over time has to be called into question.
It's common now to see people snubbing social companions to concentrate on their smartphone. But what causes this behavior -- known as 'phubbing' -- and how did it come to be regarded as normal?
You may not be anonymous as you think you are online; reveals a new study. Your browsing behavior can indicate your personality and provide a unique digital signature which can identify you, sometimes after just 30-minutes of browsing.
Mobile phone data may reveal an underlying mathematical connection between how we move and how we communicate that could make it easier to predict how diseases -- and even ideas -- spread through a population, according to an international team of researchers.
For the first time, scientists used methods of network science to solve a fundamental astrophysical problem -- explaining the so-called 'initial mass function', a distribution of stars by mass in galaxies and starclusters.
A new algorithm that could help astronomers produce the first image of a black hole has been constructed by scientists. The algorithm would stitch together data collected from radio telescopes scattered around the globe, under the auspices of an international collaboration called the Event Horizon Telescope. The project seeks, essentially, to turn the entire planet into a large radio telescope dish.
To improve the efficiency of waveguides -- devices that guide light on the surface of silicon optical computer chips -- a complex balance must be struck. The need for enhanced optical signal processing properties competes with the demand for low optical losses in waveguide material. Now researchers have developed an alloy that fits the bill while achieving compatibility with existing silicon computer chip fabrication technology.
Automated robot that scans library shelves using laser mapping and radio tags can ensure no book is misplaced again.
