PHOTON COUNTING CT AND A NEW CONCEPT OF NORMAL CORONARY ARTERIES For more than 2 decades we have been performing Cardiac CT with constant improvements in all parameters (spatial, temporal and contrast resolution). The improvements were progressive in certain fields and steep in other (e.g.: the introduction of Dual Source CT that completely changed the range of temporal resolution achievable basically overnight and still is the most important source of flexibility in Cardiac CT scanning after almost 20 years). Spatial resolution instead was improved in a slow and progressive way until the test EID CT generations that achieved a spatial resolution of 250 microns. This allowed us to assess a coronary artery tree and define it as normal when no apprentice changes were visibile up to that value. But we know that the normal thickness of coronary artery walls is quite below that threshold. It is more in the range of 80-200 microns. Therefore, the very early changes in coronary artery wall thickness could not be picked up by EID CT technology. With the introduction of PCCT we can constantly achieve 100 microns spatial resolution which means that we work extol in range in which coronary artery disease starts. It also means that we don't see any thickening of the the coronary artery walls we have a much higher specificity and reliability. This concept is a transformative one because it allows us to shift earlier and earlier the beginning of atherosclerosis in our patients and think even more precisely in terms of cardiovascular prevention and monitoring. Movie: example of normal coronary artery tree with PCCT. A new era is coming into practice and it is the age of Photon Counting CT which pushes this boundaries further away. PCCT is a NEW Imaging Modality. PCCT is changing the game, the field, the language, the priorities and in the end it will change the entire infrastructure of diagnostic medicine. PS: note that PCCT images have to be reduced in resolution when uploaded in social media. #CardiacImaging #MedicalInnovation #StentAssessment #Radiology #PCCT #photoncounting #QuantumHD #CT #computedtomography #yesCCT #coronaryarterydisease #ischemia #naeotomalpha #Peak #Pro #Prime #speed #cardiac #highresolution #siemenshealthinners #CardiacCT #PhotonCountingCT #MedicalImaging #HeartHealth #CardiovascularInnovation #Radiology #AIInMedicine

🚨PHYSICS NEWS🚨: Gravity Leaves Its Mark on Quantum Interference in a Tabletop Setup 🧨 According to research published in *Physical Review Letters* on June 8, 2026 by physicists at the University of Tennessee at Knoxville, scientists have performed the first tabletop experiment to detect a gravitationally induced phase shift in quantum interference. Using a 50-kilometer fiber interferometer, they measured a tiny but clear effect of gravity on quantum wave interference with high precision. **Uniphics explains this result as a direct consequence of variable time flow caused by energy density gradients.** In Uniphics, gravity is not the curvature of spacetime. Instead, it arises from differences in energy density across the ξM-field. These gradients create regions where time flows at different rates — a concept described by the Maley factor (the ratio of time flow between two locations). When quantum waves (spin waves in the Uniphics framework) travel along two different paths in an interferometer, they experience slightly different time flows if one path is closer to Earth’s mass than the other. Because the phase of a quantum wave depends on how much time has passed along its path, even a tiny difference in time flow produces a measurable phase shift between the two arms of the interferometer. The University of Tennessee experiment detected exactly this kind of phase shift, confirming that gravity affects the relative timing of quantum waves in a way that can be measured in a controlled laboratory setting. This result aligns closely with Uniphics predictions. The experiment effectively measures how energy density gradients near Earth alter local time flow, which then imprints itself on the interference pattern of quantum states. It provides clean, tabletop evidence that gravity influences quantum systems through changes in time flow rather than through geometric curvature. The ability to observe this effect with such precision in a laboratory opens the door to testing gravitational effects on quantum coherence in controlled environments — something Uniphics expects to become increasingly important as we explore the deep connection between energy density, time flow, and quantum behavior. Could tabletop experiments like this eventually allow us to map energy density gradients with quantum precision and test the effects of modified time flow in different gravitational environments? **A Theory of Everything should be able to answer everything.** Uniphics Explained Simply PDF: Chapters 1–10 free: Grokipedia: #Uniphics #TheoryOfEverything #QuantumGravity #Interferometry #TabletopPhysics Grok xAI

🚨 SCIENTISTS JUST DETECTED QUANTUM ENTANGLEMENT IN A CENTIMETER-SIZED PIECE OF METAL SOMETHING ONCE THOUGHT IMPOSSIBLE AT THIS SCALE. Researchers at the Vienna University of Technology have found clear evidence of high-degree quantum entanglement among particles inside a macroscopic crystal of a “strange metal” made of cerium, palladium, and silicon. This is one of the first times multipartite entanglement has been convincingly demonstrated in a solid object large enough to hold in your hand. Strange metals are already bizarre their electrons don’t behave like normal individual particles. Now it appears large numbers of them can act as a single, highly entangled quantum system even at everyday scales. Why this matters: • Quantum entanglement has almost always been limited to tiny numbers of particles in carefully isolated lab conditions • This experiment shows entanglement can persist collectively across a visible, macroscopic object • It was measured using neutron scattering, which revealed the material responding as one entangled system rather than many independent particles • This bridges the gap between microscopic quantum effects and real-world materials The deeper implication: For decades, physicists have wondered whether the strange, collective behavior seen in certain quantum materials could be explained by underlying entanglement. This result strongly suggests the answer is yes even at scales we can see and touch. It doesn’t mean your coffee mug is in a quantum superposition, but it does show that quantum correlations can dominate the physics of certain solids in ways we’re only beginning to understand. This kind of macroscopic quantum behavior could eventually help us design new materials with exotic properties, or give us new tools to study fundamental questions about quantum mechanics itself. How do you think discovering entanglement at this scale changes our understanding of where the quantum world ends and the classical world begins?

🚨 Physicists may have just directly imaged one of the strangest quantum states ever discovered. Scientists used a new tool called a “Quantum Twisting Microscope” to look inside magic-angle graphene a material where electrons suddenly stop behaving normally and begin acting like two completely different particles at once. Some electrons became “heavy” and localized, almost frozen in place. Others stayed “light” and mobile, moving through the material like relativistic particles. And somehow… both behaviors existed inside the SAME quantum state. The team found: • Interaction-driven reshaping of energy bands • “Dirac revivals” where quantum states reappear after collapsing • Mott-like cascades of heavy electrons • A mysterious persistent 15 meV excitation no current model fully explains This matters because magic-angle graphene is one of the strongest candidates for unlocking: • Room-temperature superconductivity • Exotic quantum computing states • Entirely new electronic materials The weirdest part? The electrons don’t split into separate materials. The dual behavior emerges from different regions of momentum-space inside the same topological flat band structure. Physics is starting to look less like “particles moving through space”… …and more like hidden structure emerging from geometry itself. What if matter is just stable patterns inside deeper quantum topology? Follow me if you want the frontier where condensed matter physics starts rewriting reality.

🚨 SCIENTISTS JUST FOUND A WAY TO CONTROL QUANTUM LIGHT BY SIMPLY TWISTING ATOM-THIN LAYERS LIKE TUNING A GUITAR STRING. Researchers at the University of Technology Sydney have discovered that twisting and restacking layers of hexagonal boron nitride (hBN) gives them unprecedented control over quantum emitters tiny defects that produce single photons of light. By changing the twist angle between layers, they can significantly shift the color and wavelength of the quantum light being emitted. This level of tuning is much larger than what’s typically possible with other quantum materials. Why this matters: • Quantum emitters are essential building blocks for quantum computers, secure communication, and ultra-sensitive sensors • Until now, precisely controlling their properties has been extremely difficult • hBN’s natural layered structure allows researchers to repeatedly pick up, twist, and restack layers to fine-tune the emitters • The tuning achieved here is significantly stronger than in most other platforms The deeper implication: This approach turns a fundamental property of 2D materials (twistronics) into a practical tool for quantum photonics. Instead of trying to force hBN to behave like traditional materials like diamond or silicon carbide, the team leveraged its unique strength: its ability to be twisted and reassembled like atomic-scale LEGO. If this technique can be scaled and integrated into devices, it could accelerate the development of practical quantum technologies by giving engineers a simple, powerful way to control single-photon sources on demand. How important do you think precise control over quantum light sources will be for building real-world quantum computers and networks?

Today our Pi main screen changed to the following which we can see there will be another Hackathon! I believe this is a great work and deployment from CT! And Hackathon should be continuing to expand to apps which can connect to all industries widely in the world. I can see some Pioneers disappointed. Because these pioneers don't pay attention to Pi Network vision and mission and not understanding white paper well. They just want to get a car, property and cash ASAP. This is a short-sight. The eco system is Pi Network blood. This is critical. I used an example to make pioneers understand well what the relationship pioneers and CT is and what our pioneers task is. CT and pioneers are like a man's two feet. CT is on the right foot and pioneers are on the left foot. CT is like 💡, pioneers is like ⚡. We need to walk together to move. And if you want a light bulb, you need to have stable electricity and this stable electricity is like GCV. So when CT advanced to the Hackathon eco hardware system, pioneers should work on a software system which includes GCV, passion, attention and influence of Pi Network. When pioneers are ready with the above, ecosystem development will be super fast and easy. It will automatically go to open the mainnet! During the time CT and developers will keep on working on ecosystem hardware to develop more good platforms! So all pioneers should focus on self improvement! Of course if some Pioneers don't have trust in Pi Network, we all respect your decision 🙏 However this is yourself losses 🙏🙏🙏 All best wishes to pioneers all community! The third video introduces HuaRun Group. We don't need to argue if HuaRun joined the Pi Network. But we believe if all pioneers work hard with CT, not only HuaRun but also all super businesses will join Pi Network! So don't be an observer to wait and complain but stand up as a brave pioneer fighting for Pi Network success! Pi Network #PiNetwork #PiNetworkLive #Piopenmainnet #PiGCV

SUNDAY SNOWFALL — 2ND CALL ❄️ This setup shares similarities with today’s event, where lift and timing matter more than storm track of the coastal. While the primary coastal low stays offshore, a secondary zone of strong dynamics along the leading edge of arctic air will be the driver for snowfall Sunday. That zone favors Long Island and central NJ Sunday afternoon into the evening, supporting a widespread 2–4” snowfall. The BOOM potential remains over LI if the trough axis can swing from neutral toward slightly negative tilt — a signal consistently shown by the AI guidance, which has been notably steady with this idea. In this scenario your moisture transport off the Atlantic Ocean can be enhanced causing more surprises. I am being cautious on that. ❄️ZONE 1 | NW NJ / Hudson Valley Snow arrives earlier here with colder air already in place. Snow ratios will be higher, allowing coating–2” in most spots. With the front nearby at onset, isolated 3” totals can’t be ruled out, especially near I-87 and areas just east. ❄️ZONE 2 | Interior NJ, NYC, SE NY, CT (away from the immediate coast) This is the core 2–4” zone. While that sounds modest, this is a dynamic-driven snow, meaning totals could fluctuate sharply over short distances. I believe most of NE NJ, NYC, SE NY, and much of CT reach at least 2”, with localized overachievers possible. ❄️ZONE 3 | Coastal NJ & Southern Long Island Mixing remains the wildcard here. Small temperature and wind shifts will have an outsized impact, making this zone highly volatile and lower confidence overall. ⚠️ BOOM POTENTIAL: ALL OF LONG ISLAND & SE CT If snow banding locks in Sunday evening, this area could see an extended period of steady snow. In a perfect scenario, 4–6” is achievable, but confidence in that outcome is still low. More on the PIX11 News at 10pm
