In bismuth-based cuprate superconductors, charge imbalances caused by lattice distortions generate persistent and universal patterns of spin polarization. The results supply a previously missing but essential ingredient in efforts to understand the mechanisms driving the electronic behavior of high-temperature superconductors. Read more »

These filters are capable of avoiding reflections which often inevitably arise when using not perfectly diffuse light sources.

Starting with the obvious style change, the layout remains similar, but the various charts and graphs have been tweaked visually. For example, the wellness balance chart on the app’s main page has morphed from its diamond-like design to a much more readable flower-like design.

There’s also an AI chatbot you can converse with, but as the app notes, it can only respond to fixed questions. Because of this limitation, it’s not the most useful as it repackages the insights the app already gives you. Still, as it develops, I could see the AI becoming a useful fitness companion.

The first of these plans to launch is a Body and Mind Balance plan – a Sleep improvement plan is apparently on the way, according to the app – and after answering a quick survey about your activity patterns, the software will provide specific daily targets for you to achieve so you can steadily morph from your current routine to your new healthier normal.

Those improvements to glanceability extend to other aspects of the home page and stats pages but let’s talk about new features. AI has come to the RingConn app in a big way with the introduction of Health Plans.

RingConn has published an overhaul of its smart ring app, with it getting a fresh coat of paint and a substantial upgrade that leaves the app feeling like a much more robust wellness tool. This is excellent news for anyone looking to pick up a cheap option among the best smart rings, especially right now, as it's on sale for Black Friday.

As I mentioned above, the Ai doesn’t feel entirely helpful, but overall, this RingConn app overhaul looks to be a massive boost instead of a downgrade, and I’m excited to see what improvements we get next.

Enhance visibility and precision with Skytron's procedure lights, designed for optimal performance in various clinical and surgical procedures.

The in-depth insights were useful, but I often just wanted a quick recap of my stats and a brief guide to improving. The app's facelift and health plan tool is perfect and gives me a reason to open it up more frequently, as I can now get that extra detail and daily targets in a condensed, quick-to-read fashion.

Since testing the RingConn Gen 2 for our review, I’ve kept using the ring pretty much all the time – save for the week or two I had lost it (it fell behind my bedside table) – but I’ve realized I increasingly relied on the app a lot less because the stats I cared most about were easily viewable in the Android app widget. I could easily check my sleep, activity score, and ring battery with just a brief look at my home screen.
