Modular kayaks may be easy to store and transport, but most are made of plastic, which isn't everyone's favorite material. Two new boats from Stellar are different, in that they feature sleek, stiff, glossy, lightweight composite bodies.Called the S14 MOD and the S19 MOD, both kayaks are modular versions of a non-modular kayak already in Stellar's lineup, the S14G2. They're also both offered in a choice of Advantage or Multi-Sport construction – the former sports a gel-coated fiberglass/foamcore-sandwich hull and deck,…

Most of the time, just keep it simple. Combine your composite keys into a string key for storage in a map or cache if that is the easiest option and performance is not a major concern. In scenarios where performance is critical, make sure to do your own testing. But using nested maps will be the most performant in most cases. It will also likely have the smallest storage requirements. And composite keys are still a performant alternative when nesting mappings become impractical.Read All Most of the time, just keep it…

When treating severely broken bones, doctors want new bone tissue to grow back as fast as possible, and they also want to keep the wound site from becoming infected. Scientists have developed an implantable composite material that reportedly delivers on both counts.The substance was created via the German-government-funded SCABAEGO (Scaffold Bioactive Glass-Enhanced Osteogenesis) collaborative research project.Partnering groups include the Department of Trauma and Reconstructive Surgery at the Heidelberg University…

Two-phase closed thermosyphons (TPCTs) are widely used to tackle external disturbances by cooling the permafrost stratum in permafrost engineering. However,…

Final clean Landsat composite image for the conterminous United States: (a) 2019 leaf-off, and (b) 2019 leaf-on. Credit: Answers could be cloudy for researchers using Landsat images to investigate the coverage of the continental United States. The National Land Cover Database (NLCD) are useful products for scientists to understand how things like tree canopy and road coverage changes over time, but something as simple as…

And how you need to invoke complex numbers to solve a leet-code problem on convolutionPhoto by NOAA on UnsplashMany people consider complex numbers an esoteric concept, showing up in the depths of mathematics and removed from practical applications.Now, consider that the most influential algorithm in computer vision is convolutional neural networks. So, an algorithm that performs convolutions as efficiently as possible is important. And in order to develop the most efficient algorithm, you need to invoke complex numbers.…

French startup Fairmat closed a $35 million Series A funding round (€34 million) last month. It wants to turn carbon fiber composite that is no longer in use into a new material that can be used in new products. Temasek and CNP (Compagnie Nationale à Portefeuille) are leading the round with Pictet Group, Singular, The Friedkin Group International and others also participating. Overall, the company has raised $45.5 million (€44 million) since its inception. The idea behind Fairmat is quite simple. Some high-tech…
