Eu preciso fazer uns alongamentos e algumas pequenas tarefas de casa. Mas estš um calor infernal, não estou com coragem de sair de dentro do quarto com ar-condicionado. 😬

Nice annotation of the US-Russia "peace plan" with regard to Ukraine.

The Witkoff-Dmitriev peace plan annotated
We now know a bit more about the process which led to the new peace plan and we now have a copy of its contents, to which I will turn soon.

Predictions for the world in general. Again, outside my field, so these are just guesses.
1) Recession in the US. EU economy hit hard as well.
2) The Russian NWF hits 1% of GDP. The resulting economic downturn is a deciding factor in the peace process.
3) Blue wave in the midterms. Democrats take both the House and the Senate.

Every new initiative from Washington unfolds according to the same pattern:
a diplomatic cavalry charge against Ukraine,
which Kyiv, with other European capitals, manages to fend off.
They stabilise the situation but never actually win the battle.
This pattern will, no doubt, persist.
The White House presumes that it is impossible to force Russia to relinquish the territory that it already controls in Ukraine’s south or east.
The problem is that while reco…

Abstract: Magnetometry based on diamond nitrogen-vacancy (NV) centers has been extensively studied for applications requiring diverse capabilities, spanning from nanometer spatial resolution to subpicotesla sensitivity. Among various applications, diamond magnetometers can demonstrate high sensitivity magnetic sensing within millimeter-scale size for endoscopic applications. However, the trade-off between sensitivity and spatial resolution of diamond magnetometry makes it difficult to achieve such a probe. In this study, we present a millimeter-scale rigid diamond magnetometer probe with enhanced sensitivity via optimizing the optical design. By coupling the frustum diamond with the miniaturized compound parabolic concentrator (CPC) lens, we enhance the fluorescence collection efficiency by 37% within 4 mm diameter, and the achieved sensitivity is 200 pT/Hz1/2 based on the sample with the resonance linewidth of ~8 MHz. With this verified structure, endoscopes with mm-size probe and picotesla sensitivity can be projected for surgical and industrial applications in the future.

Abstract: The discovery of optical frequency combs (OFCs) has revolutionised science and technology by bridging electronics and photonics, driving major advances in precision measurements, atomic clocks, spectroscopy, telecommunications, and astronomy. However, current OFC systems still require further development to enable broader adoption in fields such as communication, aerospace, defence, and healthcare. There is a growing need for compact, portable OFCs that deliver high output power, robust self-referencing, and application-specific spectral coverage. On the conceptual side, progress toward such systems is hindered by an incomplete understanding of the fundamental principles governing OFC generation in emerging devices and materials, as well as evolving insights into the interplay between soliton and mode-locking effects. This roadmap presents the vision of a diverse group of academic and industry researchers and educators from Europe, along with their collaborators, on the current status and future directions of OFC science. It highlights a multidisciplinary approach that integrates novel physics, engineering innovation, and advanced researcher training. Topics include advances in soliton science as it relates to OFCs, the extension of OFC spectra into the visible and mid-infrared ranges, metrology applications and noise performance of integrated OFC sources, new fibre-based OFC modules, OFC lasers and OFC applications in astronomy.
