NA62 Collaboration (2023). "Search for K + decays into the π +e +e −e +e − final state". arXiv: 2307.04579 [ hep-ex]. {{ cite arXiv}}: CS1 maint: numeric names: authors list ( link) For the Far Cry New Dawn benchmark, the x17 R2 got 87 fps, which was just shy of the 90-fps category average, but still enough to trounce the Strix G15 (81 fps). The Blade 17 got a slightly better result at 89 fps while the Raider notched 113 fps.

Of course, most Windows 10 laptops come with bloat built into the OS, and that's still the case here. Ours, for instance, had Roblox, Tik Tok, Spotify and Hidden City: Hidden Object Adventure filing up our start menu. The X17 particle is a hypothetical subatomic particle proposed by Attila Krasznahorkay and his colleagues to explain certain anomalous measurement results; these anomalous measurements are known as ATOMKI anomaly or beryllium anomaly or X17 anomaly. [2] [3] The particle has been proposed to explain wide angles observed in the trajectory paths of particles produced during a nuclear transition of beryllium-8 atoms and in stable helium atoms. [4] The X17 particle could be the force carrier for a postulated fifth force, possibly connected with dark matter, [4] and has been described as a protophobic (i.e., ignoring protons) [5] vector boson with a mass near 17MeV. [4] History [ edit ] Alienware doesn’t provide a battery life estimate for the x17 R2, but touts the various power modes as a means to ensure you can tailor performance and battery life to your needs.For music, they get decently loud, but CHVRCHES' "How Not to Drown" sounded muddy, with drums and keyboards getting lost with guitars and vocals, all fighting for dominance. Switching to the music audio preset in Alienware Command Center didn't do anything to help. Upgradeability of Alienware x17 Frame mounts provide much-needed breathing space between the canvas and the frame itself while also adding an intriguing and engaging shadow line to the edges of the picture, opening it all up to curious eyes.

We saw similar results on Far Cry New Dawn (1080p, ultra), where the x17 played at 94 fps, just behind the Raider's 99 fps, though here the other Alienware, the m17 R4, took the crown at 104 fps. The display is surrounded by relatively chunky bezels, with a 720p webcam along the top of the display’s housing. Beyond the resolution, which isn't the end-all-be-all, the picture from this webcam has an issue with color. Specifically, a red t-shirt I was wearing looked more orange when I tested the webcam out. That being said, detail was decent enough for a laptop camera, but if this is going to be your daily driver, you may want to invest in one of the best webcams. The Alienware x17 did far better on Grand Theft Auto V ( 1080p, very high), running the game at 129 frames per second, just two frames shy of the Raider, and higher than both the Blade Pro and the m17 R4. The Alienware x17 R2 comes with a 1-year limited warranty. See how Alienware fared on our annual special reports: Tech Support Showdown and Best and Worst Brands. Bottom Line

Case in point, when we ran the Shadow of the Tomb Raider benchmark, the x17 R2 notched 107 fps, which decimated the 86-fps premium gaming laptop average. Neither the Strix G 15 nor the Blade 17 stood a chance at 88 and 86 fps. However, the Raider stole the win with 112 fps.

Gutters are a critical element for a log cabin. They are used for draining water and ensuring the cabin’s safety, aesthetics and energy efficiency. All these requirements are easy to fulfil with the Ruukki steel guttering system. This system is one of the most innovative and simply the best in the market. What’s so good about it? The x17 R2 really shined on our brightness test, averaging 325 nits. That’s slightly below the 328-nit category average, but the x17 R2 is a lighthouse compared to the Strix, Blade 17 and Raider which reached 280, 277 and 259 nits, respectively. Alienware x17 R2 audio The international ISO 9001:2008 and European standard EN544 guarantees the quality of the Shinglas® bitumen shingles. Moreover, the shingles are resistant to open flames and have a much better thermal and noise insulation in comparison with other roof covering materials.And the internals are interesting, too, with quad fans and a new cooling material in Element 31. However, in my usage and testing, I did find the system can get a bit steamy. And while every game we ran was playable, and usually competitive, there were a few instances where extra heat may have been the reason that the x17 wasn't the most competitive laptop in the field. This was covered in science journalism, focusing largely on the implications that the existence of the X17particle and a corresponding fifth force would have in the search for dark matter.

One of those screws completely came out of our unit. Once I got it open, the small metal washer was loose. Alienware informed me that this would not cause warranty issues. I was surprised to learn that at 76% of the DCI-P3 color gamut, the x17 R2 missed the 85.8% premium gaming average. Still, the result was better than the Raider’s 74.5%. However, the Strix (76.7%) and Blade 17 (83.9%) were even more vivid.One thing this webcam does have going for it is infrared support, so you can use it to log in with Windows Hello facial recognition. Some gaming laptops still don't have any biometrics at all, so I appreciated the feature. Software and Warranty on Alienware x17 The standard A paper format is used internationally for print measurements. We all know what an A4 paper looks like, and we have also dealt with A1 – A2 canvases in school or so. However, what size are these A format paper standards anyway? The NA64 experiment and NA62 experiment have reported in 2021 [16] [17] and 2023 [18] [19] respectively results of conducted searches that have put stringent limits for the existence of the X17 particle.
