TL;DR: Hisense is known for offering some of the most innovative devices on the market, though many of them never make it outside of China, the company’s home turf. Fortunately, the 110-inch ULED X Mini LED TV is an exception. Priced at $20,000 through platforms like Best Buy, this colossal TV can now be yours, too.

The ULED X Mini boasts a 4K Ultra HD LED display with a 120Hz refresh rate (or 144Hz with VRR enabled). The screen utilizes quantum dot technology for enhanced color reproduction, along with Hisense’s Full Array Local Dimming Pro system, which divides the backlight into 40,960 dimming zones. This allows for an impressive 10,000 nit peak brightness while still delivering deep, inky blacks.

The TV supports all the latest HDR formats, including Dolby Vision IQ, HDR10+, and HLG. Hisense has also integrated its Hi-View AI Engine X, which dynamically adjusts image quality in real time for optimal clarity.

Regarding the ‘ULED X’ technology, Hisense claims it combines powerful processing with intelligent backlight control to deliver three times the contrast of conventional OLED TVs and twice the dynamic range.

On the audio front, the 110UX comes equipped with a built-in 102W 4.2.2 channel speaker system that supports Dolby Atmos and DTS for immersive sound.

For smart TV functionality, the 110UX runs Google TV in the US or Hisense’s Vidda U OS in Europe, providing access to all major streaming apps out of the box. It also includes four HDMI 2.1 ports for connecting gaming consoles and Blu-ray players. Game Mode Pro and AMD FreeSync Premium Pro are there to ensure what’s likely to be a sublime gaming experience.

Hisense says the arrival of the 110UX represents a “significant evolution” in its TV product line. It claims it is responding to the surging demand for big-screen entertainment by expanding its ULED and ULED X lineups to include even larger screen sizes. The lineup previously included options in 85 and 98-inch sizes, though this new 110-inch model is the largest among the bunch.

Additionally, Hisense has released a limited “Championship Edition” of the 110UX in the US to coincide with the start of the NBA season. While specific details are scarce, the company says the special edition includes “luxurious enhancements” to celebrate NBA champions. Interestingly, this limited edition is priced the same as the standard model at $19,999 and is available at Best Buy.

Outside of the US, UK customers can pre-order the 110UX for 19,999 from retailers like Crampton and Moore. In Europe, it’s available for 19,999 from specialist dealers.

Massive SpaceX Starship Capacity Makes Radiation Shielding Easy

NASA Space Technology

The radiation dose for the 2.5 year round trip between Earth and Mars should give approximately a 1% lifetime increase of a fatal cancer.

SpaceX Starship will totally change the situation on payload and travel times. The Starship will be refueled in Earth Orbit. All NASA missions to Mars have launched with multiple stages get to orbit and then to go to Mars. This means the final stage that goes to Mars has to go smaller and slower. They are about 20 times smaller than the launch rocket and they go about 2-3 times slower than a fully fueled in orbit Starship.

Starship could travel to Mars one-way in 70-90 days without extra exceptional effort beyond refueling in orbit. This is better than the 180-270 days of other vehicles. Reduced travel time would already halve or quarter the amount of radiation exposure. It would also reduce the time window when crews could be exposed to increased solar storms.

7.15 centimeters of water halves the gamma rays (500 kev or less). 71.5 centimeters of water would reduce gamma rays by 1000 times. 143 centimeters would reduce gamma rays by 1 million times. Water shielding would not be needed for the entire interior volume of Starship. It would be useful for the main sleeping, eating and living areas inside the Starship. A six-sided cube with 4 meters per side would have 96 square meter sections. If those were 71.5 centimeters thick and some tank walls, then 80 tons of material would provide 0.1% of the radiation exposure in a volume of about 64 cubic meters.

The average radiation on Earth is very low at ~6.2 milliSieverts per year (mSv per year). However, in some areas of the city Ramsar, Iran, the radiation level is 260 mSv / year, with no increase in health problems. Thus the radiation safety levels in many countries on Earth, are likely too conservative. This is good news for Mars colonists. The goal is not 6.2 mSv per year, but say 200 to 250 mSv / year.

41 times the average radiation has been proven to be safe. Passive radiation shielding is measured in thickness of material to halve the radiation level. Five levels of radition halving will not actually be necessary.

Also note that sudden radiation doses are much more dangerous than a small steady dose over a long period of time. A solar storm is FAR more dangerous than the slow and steady trickle of cosmic rays.

Long term settlers will need to shield against 3 types of radiation: Electromagnetic radiation, Solar Cosmic Rays, and more powerful Cosmic Rays. Of the last, Galactic Cosmic Rays are by far the most common fraction of these.

Massive Solar Storm Removed Earth’s ‘Tail’ and Gave It Wings Instead

NASA Space Technology

An overwhelming solar burst from the Sun hit the Earth hard enough to change its entire magnetic field, researchers have found.

Astrophysicists at NASA‘s Goddard Space Flight Center detected an explosion originating from April 2023 that disturbed its natural magnetosphere for two hours.

Similar to a supersonic jet being pelted by intense high-speed winds, Earth is perpetually bombarded by a stream of charged particles from the Sun, known as solar wind.

Usually, the Earth moves throughout the solar system with a magnetic field shaped like a tail at its nightside during interactions with solar wind. Experts often compare the shape to a windsock.

During this event, Earth’s typical magnetic tail was replaced by wings.

Observations from NASA’s Magnetospheric Multiscale Mission (MMS) establish how this could be.

This was a result of a rare phenomenon during a coronal mass ejection (CME)—where large-scale outbursts of plasma and magnetic energy erupt from the Sun’s corona, the outermost part of its atmosphere. At over 1.8 million degrees Fahrenheit, the corona is multitudes hotter than the Sun’s surface

The wings are named after the Swedish physicist Hannes Alfvén, who made significant contributions to the understanding of plasma physics.

During the unique transformation, they formed a conduit linking the magnetosphere to the CME. This connection facilitated the transfer of plasma between Earth and the Sun.

CMEs can travel from the Sun at speeds ranging from less than 155 miles per second (mi/s) to nearly 1900 mi/s.

The fastest CMEs directed at Earth may arrive in just 15-18 hours, while slower ones might take several days.

As they move away from the Sun, CMEs expand in size, and larger ones can reach dimensions that cover nearly a quarter of the distance between Earth and the Sun by the time they reach our planet.

This unique event indicates solar wind produced fluctuations in the atmosphere that are faster and more dense than previously understood.

Billions of tons of coronal material would have been expelled to an anomalous extent, as the Earth’s newly-formed wings interacted with intense solar winds.

The discovery of this CME provides valuable insights into the formation and evolution of Alfvén wings.

It has been suggested that such processes may also occur around other magnetically active bodies in our solar system and beyond.

The researchers propose that similar Alfvén wings might explain aurorae on Jupiter’s moon Ganymede and suggest investigating if Earth experiences similar auroral phenomena linked to Alfvén wings in the future.

Amidst massive protests over electricity prices, Pakistan seeks reprofiling of its international debt with China

Top Stories Tamfitronics

Updated – August 04, 2024 at 10:48 AM.| Islamabad

Top Stories Tamfitronics German News outlet DW quotes data saying that from 2022, Pakistan had $26.6 billion worth of Chinese debt, more than any other country in the world

Pakistan has sought reprofiling of more than $27 billion in debt and liabilities with friendly nations — China, Saudi Arabia, and the UAE — to secure a 37-month International Monetary Fund (IMF) bailout package and ease energy sector foreign exchange outflows and consumer tariffs, according to a report in Dawn.

Prime Minister Shehbaz Sharif said that he had written a letter to the Chinese government requesting debt reprofiling for Pakistan in an apparent bid to secure the International Monetary Fund’s approval for a $7 billion economic bailout by next month.

“I have written a letter to China, it’s a matter of public domain now, for debt reprofiling,” Shehbaz Sharif said in an address to his cabinet on Friday. This is on top of Islamabad’s request to Beijing to convert imported coal-based projects to local coal and reprofile more than $15 billion in energy sector liabilities.

German News outlet DW quotes data saying that from 2022, Pakistan had $26.6 billion worth of Chinese debt, more than any other country in the world. DW quoted an economist, Safiya Aftab, as saying that the interest rates on Chinese loans are not concessional.

“These loans were given for infrastructure, which in theory is supposed to start generating returns. The main issue in my opinion is Pakistan’s poor absorption capacity. The government was not able to progress on projects according to schedule. The more relaxations and extensions available, the better it is for Pakistan. China, aware of Pakistan’s financial struggles, often provides breathing space but occasionally leverages this debt for its interests,” Khalid was quoted as saying.

Debt reprofiling is a strategy used to restructure a country’s existing debt obligations. It involves extending the maturity dates of debt, reducing interest rates or altering other terms of the debt agreements to make repayment more manageable.

The IMF previously raised concerns about Pakistan’s external financing gaps. The Shehbaz Sharif government is also under immense pressure to bring down electricity prices by entering into negotiations with power producers.

The high cost of electricity has caused massive protests in the country. Protesters, who have taken to the streets want the government to withdraw taxes imposed on power consumption which have triggered a massive hike in bills.

The protests against the high cost of electricity are being led by Jamaat-e-Islami (JI) causing the shutting down of a major road to Islamabad, while protests were held in several other cities as well by traders. During the last fiscal year that ended on June 30, the Pakistan government approved a 26 per cent increase in the cost of electricity.

On July 13, the public, which was already bearing the brunt of rising inflation, suffered another blow after the Shehbaz administration tacked on another 20 per cent hike. Under pressure, Shehbaz Sharif has agreed to commit to lower electricity prices saying, “Doing politics on the electricity issue is tantamount to humiliating people, the government needs to lower electricity prices to boost exports”.

For the beleaguered Shehbaz Sharif, the troubles keep mounting. Last week a Gallup survey showed that business owners in Pakistan have become more pessimistic about their future because of continued political turmoil and the new tax-heavy budget.

With the Jamaat-e-Islami questioning the government for dragging its feet on critical decisions regarding Independent Power Producers (IPPs) and the Pakistan Tehreek-e-Insaaf also scheduled to hold protests the Shehbaz Shari government is in for some tough times.

According to the World Bank, debt reprofiling refers to “modifications of the aggregate schedule of future country repayments through refinancing, debt substitution, or renegotiations. ”The process can help a country if it’s facing simultaneous maturity of multiple loans or experiencing exposure issues, such as in the currency composition of its liabilities. It can also help a country mitigate currency risk, which frequently exacerbates debt sustainability issues.

PM Shehbaz informed members of the cabinet that Chinese President Xi Jinping had shown “keen interest in his idea” of using local coal to cut down imports. ”I told the president that Thar coal could help the country cut down on imports and save $1 billion in foreign exchange,” the PM said.

He also pointed out that Finance Minister Muhammad Aurangzeb had “very good meetings” in China during his recent visit, noting that efforts were underway to implement structural reforms for reducing circular debt.

”Whether consumers are industrial or household, the government of Pakistan is fully struggling day and night to extend relief,” he said, “This is the joint voice of all parties and the nation. ”Earlier, he had commended friendly ties with China.

”Nobody was ready to invest in our energy sector at the time, but China stepped in and began CPEC, it was the only country to intervene,” he had said, crediting ex-premier and PML-N President Nawaz Sharif’s government for signing the agreements for the infrastructure.

Moreover, he said that the medium-term measures for the government included addressing loans and capacity charges. According to state-owned Radio Pakistan, PM Shehbaz, while talking to a high-level Chinese delegation, informed them of the federal cabinet’s decision to exempt Chinese citizens from visa fees with effect from August 14.

The premier also said that joint ventures between the two countries in the fields of mines and minerals, information technology, export zones, industrial zones, and relocation of industry from China will further strengthen the local economy.
