Artificial neural networks decode brain activity during performed and imagined movements

Science Daily AI - Fri, 2017-08-18 08:23
Filtering information for search engines, acting as an opponent during a board game or recognizing images: Artificial intelligence has far outpaced human intelligence in certain tasks. Researchers are showing how ideas from computer science could revolutionize brain research. They illustrate how a self-learning algorithm decodes human brain signals that were measured by an electroencephalogram (EEG).

When robots help with shopping

Science Daily AI - Wed, 2017-08-09 05:37
Today, the desired book, toy or household appliance can be purchased by a click only -- thanks to online mail order business and smart logistics. The bottleneck in logistics, however, is the high-bay store, where many picking and detection processes cannot yet be executed automatically by robots. At the Amazon Robotics Challenge in Nagoya, Japan, a team has demonstrated how future warehousing may work.

Cathleen Synge Morawetz, 1923-2017

AMS Feed - Tue, 2017-08-08 23:00

Cathleen Synge Morawetz, the second woman to serve as president of the AMS (1995-1996) and the first to receive the National Medal of Science (1998) for work in mathematics, died August 7 at the age of 94. Morawetz was professor emerita at New York University's Courant Institute of Mathematical Sciences and worked in partial differential equations, establishing important results in the study of shock waves, scattering theory, transonic flow, and the nonlinear wave equation. Morawetz, whose father John Lighton Synge was also a mathematician, received her PhD from New York University in 1951 under the direction of Kurt Friedrichs. She then held a position as a research associate at MIT but returned to the Courant Institute after one year, later serving as its director from 1984 to 1988, and retiring in 1993.  Morawetz received several prizes and honors, including the 2004 Steele Prize for Lifetime Achievement, the 2006 Birkhoff Prize, election to the National Academy of Sciences and the American Academy of Arts & Sciences, was the Gibbs lecturer in 1981, and was a member of the inaugural class of AMS Fellows in 2012. Among those achievements, she was often the first or only woman to be so honored.

In her response to being awarded the Steele Prize, Morawetz wrote: "I am forever indebted to my mother for instilling in me the idea of ambition (then very unladylike) and to my father for the idea of intellectual achievement (not to mention the introduction to [Richard] Courant)." For more information on Morawetz' work and life, see her biography in the MacTutor History of Mathematics Archive, her page on the AMS Presidents Timeline, and "Happy 91st, Cathleen Synge Morawetz," by Allyn Jackson, from the May 2014 issue of Notices.

Playing with your brain

Science Daily AI - Tue, 2017-08-08 12:55
Human-computer interactions, such as playing video games, can have a negative impact on the brain, says a new Canadian study. For over 10 years, scientists have told us that action video game players exhibit better visual attention, motor control abilities and short-term memory. But, could these benefits come at a cost?

The legacies and achievements of Marina Ratner and Maryam Mirzakhani

AMS Feed - Mon, 2017-08-07 23:00

"With Snowflakes and Unicorns, Marina Ratner and Maryam Mirzakhani Explored a Universe in Motion," by Amie Wilkinson, published in The New York Times August 7, is on "the legacies and achievements of two great mathematicians [who] will dazzle and intrigue scholars for decades." Wilkinson's essay provides a historical and personal perspective on both women--their backgrounds, mathematics, and impact on current and future mathematics and mathematicians. "I was inspired by both women and their patient assaults on deeply difficult problems. Their work was closely related and is connected to some of the oldest questions in mathematics," writes Wilkinson. "Dr. Ratner and Dr. Mirzakhani studied shapes that are preserved under more sophisticated types of motions, and in higher dimensional spaces." Wilkinson describes their important work, its far-reaching applications, and their legacies--which include inspiring a new generation of young women. "For the inspiration they provide, but above all for the beauty of their mathematics, we celebrate their lives."

Science Daily AI - Wed, 2017-08-02 09:05
Computer science researchers have developed a tool for use with the game Skyrim that can be used to create nonplayer characters that allow for more variability and flexibility in game play. The tool, called CIF-CK, is an artificial intelligence architecture program that uses social behavior models to make individual NPCs more reactive and adaptable to player behavior.

Smaller, smarter, softer robotic arm for endoscopic surgery

Science Daily AI - Wed, 2017-08-02 08:30
Researchers have developed a hybrid rigid-soft robotic arm for endoscopes with integrated sensing, flexibility, and multiple degrees of freedom. This arm -- built using a manufacturing paradigm based on pop-up fabrication and soft lithography -- lies flat on an endoscope until it arrives at the desired spot, then pops up to assist in surgical procedures.

FSF announces new fiscal sponsorship for SeaGL conference

FSF News - Tue, 2017-08-01 11:43

As part of its Working Together for Free Software Fund, the FSF provides fiscal sponsorship for a number of important free software and GNU technical projects, such as the GNU Toolchain and Replicant. Today, SeaGL becomes the first event to receive this sponsorship.

SeaGL is a grassroots technical conference dedicated to spreading awareness and knowledge about the GNU/Linux community, free software, and freedom-respecting hardware. Their interest in free software extends to how they manage the conference, using tools like Jekyll and OSEM, and making sure that nonfree software is not required for attendee registration. In 2016, SeaGL had an attendance of more than 300.

"SeaGL educates new contributors about free software values and provides a friendly forum for community members to share news and tips about free software tools. We can't imagine an organization more in line with our goals than the FSF," said SeaGL board member Deb Nicholson.

As a fiscal sponsor, the FSF will assist SeaGL by providing services required by a legal entity, including the signing of contracts and receiving and processing payments.

"We have always been impressed with the Seattle GNU/Linux Conference's dedication to free software," said John Sullivan, executive director of the FSF and prior speaker at SeaGL. "We are excited to support what they are doing. Conferences are invaluable for building momentum and community within free software."

The FSF has already been represented at SeaGL for several years. FSF staff and volunteers have run an expo table. Richard Stallman, FSF founder, delivered a keynote in 2014. Past speakers include FSF board of directors members Benjamin Mako Hill and Bradley Kuhn. Staff members Donald Robertson III, Georgia Young, and Molly de Blanc have also spoken at the event.

Organizations interested in learning about sponsorship opportunities for SeaGL can view the SeaGL 2017 Sponsors prospectus, and individual supporters can visit the conference's contribution page.

Other free software focused events interested in fiscal sponsorship should contact the FSF at campaigns@fsf.org.

Somersaulting simulation for jumping bots

Science Daily AI - Wed, 2017-07-26 16:43
Engineers have been developing new technologies to enable robots and humans to move faster and jump higher. Soft, elastic materials store energy in these devices, which, if released carefully, enable elegant dynamic motions. A pair of new computational methods takes first steps towards automating the design of the dynamic mechanisms behind these movements.
