Accelerated MRI protocols routinely involve a predefined sampling pattern that undersamples the k-space. Finding an optimal pattern can enhance the reconstruction quality, however this optimization is a challenging task. To address this challenge, we introduce a novel deep learning framework, AutoSamp, based on variational information maximization that enables joint optimization of sampling pattern and reconstruction of MRI scans. We represent the encoder as a non-uniform Fast Fourier Transform that allows continuous optimization of k-space sample locations on a non-Cartesian plane, and the decoder as a deep reconstruction network. Experiments on public 3D acquired MRI datasets show improved reconstruction quality of the proposed AutoSamp method over the prevailing variable density and variable density Poisson disc sampling for both compressed sensing and deep learning reconstructions. We demonstrate that our data-driven sampling optimization method achieves 4.4dB, 2.0dB, 0.75dB, 0.7dB PSNR improvements over reconstruction with Poisson Disc masks for acceleration factors of R =5, 10, 15, 25, respectively. Prospectively accelerated acquisitions with 3D FSE sequences using our optimized sampling patterns exhibit improved image quality and sharpness. Furthermore, we analyze the characteristics of the learned sampling patterns with respect to changes in acceleration factor, measurement noise, underlying anatomy, and coil sensitivities. We show that all these factors contribute to the optimization result by affecting the sampling density, k-space coverage and point spread functions of the learned sampling patterns.

Financial executives are focusing on the potential benefits of Trump's support for the crypto industry, hoping for legislation that will make it easier for companies to enter the cryptoassets market. However, the recent launch of Trump's memecoin, which quickly lost value, could complicate efforts to pass digital-asset legislation through Congress. Despite the controversy surrounding the memecoin, some executives at Davos are cautiously exploring their own entry into the crypto space. The future of crypto regulation and adoption remains uncertain as political tensions and concerns about maturity in the market persist. [Extracted from the article]

Veon Ltd., a telecommunications company based in Dubai, is in discussions with Elon Musk's Starlink to enhance their collaboration for satellite-powered cellular services in regions beyond Ukraine. The company aims to provide space-based connectivity in areas where traditional networks do not reach, such as Pakistan, Bangladesh, Kazakhstan, and Uzbekistan. Veon's strategy involves expanding into under-served markets for telecom access, with plans to venture into financial services and entertainment sectors. Starlink, a unit of SpaceX, is among the companies exploring satellite-based connectivity for consumer smartphones, with recent approvals for commercial use in the United States and potential discussions with the Italian government for secure communications.

Israeli technology startups are expected to raise more funds in 2025 compared to the previous year, attributed to the Gaza ceasefire and lower interest rates. The nation's innovation chief, Alon Stopel, anticipates increased investment from venture capital funds in the country. Despite the challenges faced by Israeli companies during the fifteen-month war, there is optimism for a more lasting peace and a potential surge in new startups. Additionally, the relationship between Israel and the US, particularly under President Trump's administration, is seen as beneficial for Israeli companies, with hopes for continued support in accessing advanced technology.

The United Arab Emirates criticized the European Union for keeping it on a "black list" of countries with deficiencies in combating illicit money flows. The UAE's Economy Minister expressed concerns about the EU's labor requirements and the potential impact on industries like oil and natural gas. Despite efforts to address the situation, the EU has not removed the UAE from its black list, even though the Financial Action Task Force removed it from its "gray list" last year.

According to a Bloomberg article, the CEO of Randstad NV believes that Donald Trump's presidency could have a positive impact on the job market due to optimism about deregulation, growth, and innovation in the US. While there is uncertainty regarding immigration policies, the US is expected to see liberalization of regulations and pro-business tax policies under Trump. Despite challenging economic conditions in Europe, employees are prioritizing work-life balance over pay, and are becoming more assertive in their demands from employers.

The Dutch government is considering legislation that would require screening for scientists and master's degree students entering technology programs to prevent spying. The screening would apply to all individuals, regardless of nationality. This initiative follows a previous attempt to restrict Chinese students from sensitive technology programs due to concerns about economic security. The government aims to address challenges in assessing risks associated with economic and scientific cooperation with China. [Extracted from the article]

The Netherlands has implemented stricter export control rules for ASML Holding NV, requiring the company to apply for licenses with the Dutch government instead of Washington for certain tools. These rules, effective from April 1, pertain to specific measuring and inspection equipment made by Dutch semiconductor gear makers like ASML and ASM International NV. The US has also updated its list of restricted technologies, including metrology and software, and placed restrictions on chip factories, particularly in China. ASML, a key producer of lithography machines for high-end chips, has faced limitations in selling its most advanced machines to China due to US-led export restrictions. The US government has been urging allies like the Netherlands to impose broader export controls on China to safeguard national security interests. China, a significant market for ASML, has expressed concerns over these restrictions, emphasizing the impact on the global semiconductor supply chain. [Extracted from the article]

Eindhoven University of Technology, a key talent feeder for chip machine maker ASML Holding NV, suspended classes and shut down its computer network due to a cyberattack. The attack prompted the university to take necessary measures to prevent further damage, with no lectures or educational activities until at least Wednesday. While there is no evidence of data theft, investigations are ongoing, and the hackers' identity remains unknown. ASML has heavily invested in the university to train future employees, and this incident is not the first cybersecurity issue the institution has faced. [Extracted from the article]

Veon Ltd. has announced plans to list its subsidiary Kyivstar, Ukraine's largest mobile phone operator, on the Nasdaq exchange in New York through a special purpose acquisition company. The deal, with veteran dealmaker Betsy Cohen's Cohen Circle Acquisition Corp. I SPAC, aims to make Kyivstar the first purely Ukrainian investment opportunity to be publicly listed on a US stock exchange. Veon will retain a majority stake in the listed firm, and Kyivstar has committed to investing $1 billion in Ukraine's digital infrastructure over a five-year period. [Extracted from the article]

Veon Ltd. has announced plans to list its subsidiary Kyivstar, Ukraine's largest mobile phone operator, on the Nasdaq exchange in New York through a special purpose acquisition company. The deal, which would make Kyivstar the first purely Ukrainian investment opportunity on a US stock exchange, aims to indirectly list the firm while Veon retains a majority stake. Kyivstar has committed to investing $1 billion in Ukraine's digital infrastructure over a five-year period and recently partnered with Elon Musk's Starlink to introduce satellite-powered cellular service in Ukraine.

Europe's largest pension fund, Stichting Pensioenfonds ABP, sold its entire €571 million stake in Tesla Inc. in the third quarter due in part to concerns over Elon Musk's remuneration package. The fund cited issues with Musk's pay, costs, return on investment, and responsible investment requirements as reasons for divesting. Additionally, poor working conditions at Tesla were mentioned as a factor in ABP's decision. Musk's record-setting pay package was recently invalidated by a Delaware judge, despite shareholder approval, with ABP previously voting against it as well. [Extracted from the article]
