تست اولین قطار 35،000 تنی در چین با قلاب China Tests World's First 35,000-ton Multi-unit Hook-free Train
برای اولین بار در جهای روز 8 دسامبر 2025 ( 17 آذر 1404) در مغولستان چین یک قطار 35،000 تنی تست شده که شامل 7 قطار 5،000 تنی مجزا بودهاست که توسط یک شبکه بیسیم (Wireless) با هم ارتباط داشتهاند، یعنی قلابهای این 7 قطار به هم وصل نبوده و براساس برنامه و سیگنالینگ خاص با هم عمل می کردهاند. این سیستم براساس نرمافزار طرلحی شده در Iچین تستهای موفق حرکت و ترمزگیری را بدون تداخل یا برخورد قطارها پشت سر گذاشتهاست. مزیت این سیستم عدم گسیختگی قلابها بدلیل سنگینی قطار و برنامهریزی راحت برای جداسازی قطارها و ارسال هر قطار به مقصد نهائی بدون توقف و مانورهای اضافی است. #قلاب #چین #بیسیم #Coupling #China #Wireless

That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future. Telegram has gained a reputation as the “secure” communications app in the post-Soviet states, but whenever you make choices about your digital security, it’s important to start by asking yourself, “What exactly am I securing? And who am I securing it from?” These questions should inform your decisions about whether you are using the right tool or platform for your digital security needs. Telegram is certainly not the most secure messaging app on the market right now. Its security model requires users to place a great deal of trust in Telegram’s ability to protect user data. For some users, this may be good enough for now. For others, it may be wiser to move to a different platform for certain kinds of high-risk communications. If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means it’s less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isn’t as secure earned it some criticism. If you’re looking for something that is considered more reliable by privacy advocates, then Signal is the EFF’s preferred platform, although that too is not without some caveats. You may recall that, back when Facebook started changing WhatsApp’s terms of service, a number of news outlets reported on, and even recommended, switching to Telegram. Pavel Durov even said that users should delete WhatsApp “unless you are cool with all of your photos and messages becoming public one day.” But Telegram can’t be described as a more-secure version of WhatsApp. The last couple days have exemplified that uncertainty. On Thursday, news emerged that talks in Turkey between the Russia and Ukraine yielded no positive result. But on Friday, Reuters reported that Russian President Vladimir Putin said there had been some “positive shifts” in talks between the two sides.
