Reconfigurable device can simplify semiconductor circuit design and enhance computational power and speed — ScienceDaily

Many electronic devices today are dependent on semiconductor logic circuits based on switches hard-wired to perform predefined logic functions. Physicists from the National University of Singapore (NUS), together with an international team of researchers, have developed a novel molecular memristor, or an electronic memory device, that has exceptional memory reconfigurability.

Unlike hard-wired standard circuits, the molecular device can be reconfigured using voltage to embed different computational tasks. The energy-efficient new technology, which is capable of enhanced computational power and speed, can potentially be used in edge computing, as well as handheld devices and applications with limited power resource.

“This work is a significant breakthrough in our quest to design low-energy computing. The idea of using multiple switching in a single element draws inspiration from how the brain works and fundamentally reimagines the design strategy of a logic circuit,” said Associate Professor Ariando from the NUS Department of Physics who led

The Education of a Part-Time Punk

My father’s favorite sound was the sound of the kora, a harp-like instrument with twenty-one strings held taut between a wooden neck and a calabash body. He was from the Gambia, in West Africa, a smart and peculiar boy who left his village for the big city, Banjul, and then left Banjul for college and graduate school and a long career in America as a historian of Christianity and Islam. Perhaps the kora reminded him of the village life he had left behind. He named me after a legendary warrior who is the subject of two important compositions in the kora tradition, “Kuruntu Kelefa” and “Kelefaba.” When I was a kid, in suburban New England, I thought of my dad’s beloved kora cassettes as finger-chopping music, because of the keening voices of the griots, who sounded to me as if they were howling. Everyone’s a critic. Especially me, it turned

Hispanic Heritage Month events feature art, education, activities for kids

LAS VEGAS (KLAS) — National Hispanic Heritage Month will include a variety of celebrations and events in coordination with the City Of Las Vegas from Sept. 10 through Oct. 22:

The Fruits of Our Labor Exhibition by Justin Favela

  • Open 2 to 6 p.m. Tuesday through Friday, through Nov. 4, 2021.
  • Free and open to the public.
  • Mayor’s Gallery, Historic Fifth Street School, 401 S. Fourth St.
  • Award-winning international artist Justin Favela brings his trademark piñata paper technique to the Mayor’s Gallery at the Historic Fifth Street School to kick off Hispanic Heritage Month and the Las Vegas Book Festival. Inspired by Mexican still-life fruit of the 19th century, and paying homage to “cartoon fruit” and to the Sandra Cisneros vignette “The Monkey Garden” from her award-winning book, “The House on Mango Street,” Justin Favela created piñata-style depictions of fruit objects in both two- and three-dimensional forms.

24 schools test high for carbon dioxide, but Education Department says they’re safe

Editor’s Note: A previous version of this story incorrectly identified a list of 24 schools as being those across the province with elevated carbon dioxide levels. In fact, they were the 24 Anglophone West District schools that don’t have mechanical ventilation systems.

Some of the New Brunswick schools that lack adequate ventilation systems have tested high for carbon dioxide, CBC News has learned, less than a week before students and teachers resume in-person classes.

Of the 60 schools with no integrated mechanical ventilation systems, air quality results for 24 of them found that “certain rooms, although safe, did have carbon dioxide (CO2) levels above 1,500 parts per million (ppm), which are less than optimal for learning,” said Department of Education spokesperson Danielle Elliott.

She did not say how high the readings were, but did say it is not until levels reach 5,000 ppm over an eight-hour period weighted average, or
