Abstract: Berg and Ulfberg and Amano and Maruoka have used CNF-DNF-approximators to prove exponential lower bounds for the monotone network complexity of the clique function and of Andreev’s function. We show that these approximators can be used to prove the same lower bound for their non-monotone network complexity. This implies P not equal NP.
Honey bees really are tiny hardworking superheroes of the insect world — not only do they keep our agriculture going by pollinating many of our crops, but they also produce a myriad of beneficial substances, like honey and beeswax.
For thousands of years honey has been prized for its topical antiseptic properties. But now researchers have discovered that its lesser-known cousin, royal jelly, has special molecules that speed up wound healing.
Royal jelly is the superfood worker bees secrete and feed all their larvae, especially the queen bees. While queens are developing, they basically float in a pool of this stuff, and humans have figured out how to stimulate queen larva production to then harvest the royal jelly.
Famously described as ‘the deepest problem in solid state physics’ by Nobel Laureate, Philip Andersen, the glass transition, by which a liquid transforms into a solid without freezing, is shedding its mystique.
Until now, researchers’ understanding has been splintered at best, with mutually incompatible interpretations of the physical processes underlying the emergence of amorphous solids (glasses).
Now a team of scientists from the University of Bristol and Johannes Gutenberg Universität Mainz in Germany may have found the missing fragment, enabling the reconciliation of differing interpretations.
In addition to an upcoming virtual reality hub at NYU, New York City will also host its first VR-focused convention later this year. The NYVR Expo, which will take place at the Javits Center from Oct. 26th through 28th, aims to be the biggest virtual reality conference on the East Coast. It’ll be a place for both newcomers and existing VR professionals to explore what’s next in the burgeoning medium. And since the NYVR Expo will run alongside the PhotoPlus Expo at Javits, it will have easy reach to a wide audience of media enthusiasts.
According to Emerald Expositions, which organizes both shows, the new event came about after it noticed that PhotoPlus Expo attendees were increasingly interested in VR. While it considered creating a small virtual reality pavilion as part of the existing show, according to Senior Vice President John McGeary, the company realized it made more sense to start a completely new conference. Together, both the NYVR Expo and PhotoPlus Expo are expected to gather around 20,000 attendees.
As you’d expect, the virtual reality conference will show off how the technology can be used in a variety of sectors, including health care, education and entertainment. It’ll also take advantage of NYC’s unique position as a melting pot for a variety of industries.
Researchers have achieved a major turning point in the quest for efficient desalination by announcing the invention of a graphene-oxide membrane that sieves salt right out of seawater.
At this stage, the technique is still limited to the lab, but it’s a demonstration of how we could one day quickly and easily turn one of our most abundant resources, seawater, into one of our most scarce — clean drinking water.
The team, led by Rahul Nair from the University of Manchester in the UK, has shown that the sieve can efficiently filter out salts, and now the next step is to test this against existing desalination membranes.
In a major step towards creating a tricorder, University of Illinois at Urbana-Champaign researchers have invented a device that allows smartphones to perform the kinds of lab-grade medical diagnostic tests that previously had to be done on large and expensive instruments.
The device, called a spectral transmission-reflectance-intensity (TRI)-Analyzer, plugs into a smartphone and is able to run tests on a patient’s blood, urine, or saliva as reliably as clinic-based instruments that cost thousands of dollars. The researchers say their TRI Analyzer costs only $550.
“Our TRI Analyzer is like the Swiss Army knife of biosensing,” said Prof. Brian Cunningham, the Donald Biggar Willett Professor of Engineering and director of the Micro + Nanotechnology Lab at Illinois.
