    Kirti Vardhan Singh @KVSinghMPGonda · 14h Visited Max Super Speciality Hospital, Saket and AIIMS New Delhi and met those injured in the tragic fire incident in Malviya Nagar, including foreign nationals.

    Praying for the speedy recovery of all those undergoing treatment. Deepest condolences to the families who have lost their loved ones.

    Ministry of External Affairs remains in close touch with the concerned Embassies and is extending all necessary assistance. Commend the dedicated efforts of the doctors, nurses, and hospital staff whose timely and exceptional care has been instrumental in saving lives and treating the injured.

    I also appreciate the swift response of the local MLA Shri Satish Upadhyay Ji ( @upadhyaysbjp ) and BJP karyakartas, who played a vital role in providing immediate rescue and relief to those affected.

    Abstract

    When a photon traverses a cloud of atoms without scattering, how much time does it spend as an atomic excitation? To address this question, we used the cross-Kerr effect to weakly probe the degree of atomic excitation caused by a transmitted resonant “signal” photon by measuring the phase shift induced on a (separate, off-resonant) “probe” beam, postselected on cases when the signal photon is transmitted. The time integral of this observed phase shift, properly normalized and averaged over many runs in which the photon is detected after transmission, is the excitation time of interest, in a weak-valued sense. We measured mean atomic excitation times ranging from (−0.82±0.31)⁢𝜏0 for the most narrow band pulse to (0.54±0.28)⁢𝜏0 for the most broadband signal pulse, where 𝜏0 is the non-post-selected excitation time, given by the scattering probability multiplied by the atomic lifetime 𝜏sp . Across a range of pulse durations and optical depths, our results are consistent with the recent theoretical prediction that the weak value of the atomic excitation time caused by a transmitted photon equals the group delay experienced by the light. Our experimental results show that negative times are not limited to describing the shift in the peak of a reshaped wave packet (as resulting from group delay), but they also provide the appropriate description of the weak-valued time the photon spends as an atomic excitation.

    Atomic excitation refers to the process where an electron in an atom absorbs energy and moves to a higher energy level or orbit.

  • Brembo’s new “Sensify” braking system takes that one step further, eliminating the hydraulic system entirely and relying instead purely on electronic brake-by-wire and electric motors. Brembo is positioning its system as a plug-and-play solution that can be integrated at both the platform level (as part of a dedicated zonal architecture) or as part of an existing ecosystem, perhaps as part of a supplemental ADAS package.

    “Designed as a scalable and adaptable solution, Sensify is engineered to support a wide range of advanced vehicle architectures, from next-generation driver assistance systems to fully autonomous applications, marking a key milestone in the evolution of braking toward a truly software-defined future,” Brembo said in its announcement.

    But officer, I couldn’t pull over. The car kept telling me “Update in progress. 93% complete.”













  • This is a serious problem for the Internet. While there are sites like https://512kb.club/ (it features lightweight websites with content), but there’s not an easy way to learn about new or niche sites.

    According to https://growthbadger.com/traffic-study/ from April 5, 2020 (yes, it’s 6 years old)

    What 3.25 Billion Website Visits Tell Us About the Internet’s Top Traffic Sources

    1. Search is the single largest online traffic source, driving well over 50% of most industries’ web traffic.
    1. Google drives 8 times more traffic than all social media networks combined.
    1. The average top blog gets 66.47% of its traffic from search, of which 99.77% is organic and only 0.23% is paid.
    1. In almost every industry, Facebook still sends more traffic than all other social networks. The two exceptions are Design and Development (for which the top network is YouTube) and Crypto (for which it is Twitter).
    1. The niche that is most reliant on Google is Health and Medical, with 87.85% of its traffic coming from search.
    1. The niche that is least reliant on Google is Crypto, with 45.74% of its traffic coming from search.
    1. Facebook delivers 65.36% of all social media traffic: more visits per month than all other social networks combined.
    1. Instagram drives very little traffic: under 1% overall across all niches. Even fashion and beauty brands that were launched by Instagram influencers (e.g. Kylie Cosmetics) receive less than 5% of their monthly visits from Instagram — while search brings in about 10 times as many.
    1. The niche that is most reliant on Facebook is Business and Marketing, which gets 13.52% of its traffic from the network.
    1. Reddit drives over 3 times as much traffic to blogs as YouTube.
