Finally, portable thermal imaging devices could be here soon.

The primary source of infrared radiation is heat—the radiation produced by the thermal motion of charged particles in matter, including the motion of the atoms and molecules in an object. The higher the temperature of an object, the more its atoms and molecules vibrate, rotate, twist through their vibrational modes, the more infrared radiation they radiate. Because infrared detectors can be “blinded” by their own heat, high-quality infrared sensing and imaging devices are usually cooled down, sometimes to just a few degrees above absolute zero. Though they are very sensitive, the hardware required for cooling renders these instruments less-than-mobile, energy-inefficient and limits in-the-field applications.

A paper published this week in the journal Optics Express, from The Optical Society (OSA), describes a new type of portable, field-friendly, mid-infrared detector that operates at room temperature. Room-temperature operation, notes Andreas Harrer of the TU-Wien Center for Micro- and Nanostructures, Austria and the first author of the paper, “is essential for detectors to be energy-efficient enough for portable and handheld applications. We want to pave the way to an infrared-detection technology which is flexible in design and meets all requirements for compact integrated field-applicable detection systems.”

Interesting work on solar energy and Q-dot photosensitizers.

Interfacial triplet-triplet energy transfer is used to significantly extend the exciton lifetime of cadmium selenide nanocrystals in an experimental demonstration of their molecular-like photochemistry.

Excellent article on improving crystalized formations & usage.

According to conventional understanding, if the interactions are isotropic (where all spin directions are possible), this phenomenon can occur if the spins are arranged in triangular geometries and the interactions between them are antiferromagnetic favouring antiparallel alignment of the spins. For three atoms forming the corners of a triangle, the electronic spin of one atom cannot simultaneously be oriented antiparallel to those on both the other two atoms. In real materials that contain triangular units coupled by antiferromagnetic interactions this “frustration” can prevent the spins from coming to rest in a particular orientation even at absolute zero temperature, instead they move collectively like atoms in a liquid. By contrast, ferromagnetic interactions do not give rise to frustration in isotropic magnets because mutually parallel alignment of the spins can always occur. For these reasons, only a few isotropic materials have been proposed as spin liquid candidates.

Abstract: We prove a lower bound on the information leakage of any classical protocol.

Computing the equality function in the simultaneous message passing (SMP) model. Our bound is valid in the finite length regime and is strong enough to demonstrate a quantum advantage in terms of information leakage for practical quantum protocols. We prove our bound by obtaining an improved finite size version of the communication bound due to Babai and Kimmel, relating randomized.

Communication to deterministic communication in the SMP model. We then relate. information leakage to randomized communication through a series of reductions.

We first provide alternative characterizations for information leakage, allowing us to link it to average length communication while allowing for. shared randomness (pairwise, with the referee). A Markov inequality links this.

BTW — make sure you view that reference whitepaper on the new quantum algorithms on OEM boards.

ComNav Technologies has released its new generation Quantum algorithm to international market. The Quantum algorithm can be easily achieved through a firmware upgrade (version 2.5.2 and above), and suits all ComNav OEM boards and OEM-based receivers.

The public was unenthusiastic on all counts, even about protecting babies from disease.

Americans aren’t very enthusiastic about using science to enhance the human species. Instead, many find it rather creepy.

A new survey by the Pew Research Center shows a profound distrust of scientists, a suspicion about claims of progress and a real discomfort with the idea of meddling with human abilities. The survey also opens a window into the public’s views on what it means to be a human being and what values are important.

After more than 25 years of searching, neuroscientists in the UK recently announced that they’ve discovered a woman who has an extra type of cone cell — the receptor cells that detect colour — in her eyes.

According to estimates, that means she can see an incredible 99 million more colours than the rest of us, and the scientists think she’s just one of a number of people with super-vision, which they call “tetrachromats”, living amongst us.

Most humans are trichromats, which means we have three types of cone cells in our eyes.

Golf, offshore powerboat racing, sky diving: David Hare had led an active lifestyle. Then, in February 2011, he was diagnosed with ALS, a neurological disease that leads to rapid progressive degeneration of nerve cells, the loss of the ability to control muscle movement, and eventually death. The 56-year-old Michigan resident, who was told by doctors that he had less than five years to live, found a new lease of life last year with Obi, a robot that helps the differently abled feed themselves.
