Linear polarization holography
In conventional holography, the hologram is formed by recording the interference fringes of two coherent beams using a photosensitive material. The amplitude and phase information of the original signal wave can be reconstructed correctly when readin.....»»
Is political polarization unique to the US?
About 10 years ago, political scientist James Adams saw something troubling. New polls asked Americans whether they agreed or disagreed that people in the opposing political party weren't simply wrong but evil. Nearly half of people from both politic.....»»
Political polarization poses health risks, new analysis concludes
News coverage of the 2024 election season has often centered on how partisan division has affected our politics. But a new analysis shows that political polarization also poses significant health risks—by obstructing the implementation of legislati.....»»
Q&A: Expert shares opinions on how to depolarize social media
At a time when political polarization is becoming an increasing problem on social media, WashU data scientist Jean Springsteen is working on a way to bring down the temperature and still get buy-in from social media companies......»»
Megastudy tests crowdsourced ideas for reducing political polarization
Showing sympathetic figures with differing beliefs, discussed over a drink. Highlighting a shared identity. Correcting misperceptions about opposing partisans' views on democracy. Those are a few of the most effective strategies for reducing politica.....»»
Researchers create a three-dimensional multi-focus laser for glass micro-sculpting
Glass materials are widely used in optical and optoelectronic devices due to their low cost and excellent mechanical and optical properties. Among them, glass concave/convex linear structures with feature sizes ranging from several micrometers to hun.....»»
Study: Disappointment, not hatred is driving polarization in the states
A new study is redefining how we understand affective polarization. The study proposes that disappointment, rather than hatred, may be the dominant emotion driving the growing divide between ideological groups......»»
The transition to a circular bioeconomy requires getting prices right, study says
Conventional food and agricultural production systems employ a linear "take, make, waste" approach: taking natural resources from the Earth to make food and fuel, generating waste that contaminates the soil and water, and emitting harmful pollutants......»»
Hulu Plus Live TV: plans, price, channels, bundles, and more
Ready to ditch your cable box, but want to hang onto linear programming? You should take a look at Hulu Plus Live TV. Here’s everything you should know......»»
Pinpointing the key size for rapid tropical cyclone intensification
Accurately predicting how rapidly tropical cyclones (TCs) will intensify is a significant challenge due to the complex processes involved. Limited observations show that smaller TCs tend to intensify faster, suggesting a simple linear relationship be.....»»
Romancing SaGa 2: Revenge of the Seven puts a promising twist on turn-based RPGs
Romancing SaGa 2: Revenge remakes a classic non-linear RPG from 1993, but it's turn-based combat is still feeling modern based on what we've played......»»
Few anti-immigration users dominate most UK-based Twitter anti-immigration content with rapid spread, high polarization
A study of more than 200,000 tweets from 2019 and 2020 finds that anti-immigration content spreads faster than pro-immigration tweets, and that a few users disproportionally generated most of the UK-based anti-immigration content. Andrea Nasuto and F.....»»
Spin-controlled generation of a complete polarization set with randomly interleaved plasmonic metasurfaces
Optical metasurfaces are finely crafted two-dimensional artificial nanostructures composed of meticulously designed arrays of ultrathin artificial atoms. These surfaces possess capabilities beyond natural materials, enabling multifunctional control o.....»»
Complete-basis-reprogrammable coding metasurface for generating dynamically-controlled holograms
An article in Opto-Electronic Advances, discusses complete-basis-reprogrammable coding metasurface for generating dynamically-controlled holograms under arbitrary polarization states......»»
Scientists create ultracompact polarization-entangled photon sources for miniaturized quantum devices
Scientists have created an ultra-thin light source that emits pairs of polarization-entangled photons. These specially correlated photons hold promise for future quantum technologies, including ultra-secure communication, powerful computation, and hi.....»»
Correcting misperceptions of opposing party won"t reduce polarization, study finds
Political animus between Republicans and Democrats in the United States is alarmingly high, raising fears of undemocratic or even violent actions. An often-touted intervention to prevent political polarization is to identify and correct misperception.....»»
Achieving enhanced energy storage performance and ultra-fast discharge time in tungsten-bronze ceramic
It is widely recognized that achieving high energy storage density and efficiency in ferroelectric ceramics relies on their ability to exhibit high saturation polarization and low residual polarization, which are essential for excellent energy storag.....»»
Polarization volume gratings break uniformity-efficiency tradeoff in AR waveguide displays
Augmented reality (AR) has evolved from a futuristic concept to a widespread technology, thanks to advancements in microdisplay technologies, ultracompact imaging optics, and high-speed digital processors......»»
3 BritBox shows you should watch in August 2024
The era of streaming has pretty definitive pros and cons. Cable was expensive, but it led to a more linear experience where you know what you subscribed to, and could watch what you wanted only when it was on. Streaming allows for more choice, but wi.....»»
Bacteria encode hidden genes outside their genome; do we?
Since the genetic code was first deciphered in the 1960s, our genes have seemed like an open book. By reading and decoding our chromosomes as linear strings of letters, like sentences in a novel, we can identify the genes in our genome and learn why.....»»
Polarization and wavelength routers based on diffractive neural network
The concept of deep diffractive neural networks (D2NN) was introduced by Professor Ozcan's research team in 2018. D2NN combines the principles of light diffraction with the functionalities of neural networks. It consists of a series of continuous dif.....»»
