Improving the performance of 3D image model compression based on optimized DEFLATE algorithm

This study improves the DEFLATE algorithm for NX 3D image model compression. DEFLATE outperforms the Wavelet and C-Bone algorithms, offering higher compression ratios, shorter compression times, and increased data throughput, especially for small and medium models. It also enhances reliability in large model compression. The study highlights DEFLATE's effectiveness and provides insights for future research.

Web2Code: A Large-scale Webpage-to-Code Dataset and Evaluation Framework for Multimodal LLMs

MLLMs struggle with webpage screenshots and HTML code generation. Web2Code addresses this with a new benchmark and large-scale dataset for instruction tuning. It enhances existing datasets and creates new webpage images, pairing them with instructions to generate HTML code.

New method for generating monochromatic light in storage rings

A new method for generating monochromatic light in storage rings involves using a pulsed laser to modulate the energy of an electron beam, making the emitted radiation coherent and highly powerful. This technique, proposed by physicists in 2010, significantly boosts the radiant power to several kilowatts, making it millions of times more powerful than traditional methods. This breakthrough has potential applications in materials research.

Photochemistry sheds light on the direct functionalisation of native sugars

A new photochemical reaction creates glycosidic bonds in native sugars without protective groups, simplifying the process. Researchers developed a stable 'reactive intermediate' that easily couples with various nucleophiles, including proteins. This method, praised by Nobel laureate Carolyn Bertozzi, allows for the creation of more stable sugars and sugar mimics, with potential applications in drug development.

Pulmonary Arterial Hypertension Drug OK'd by Europe

Winrevair (sotatercept) received a positive opinion from the European Medicines Agency for treating pulmonary arterial hypertension in adults with WHO functional class II-III. It improves exercise capacity when used alongside other PAH therapies.

Plant-based meats may boost heart health despite being ultra-processed, study finds

Plant-based meat alternatives (PBMAs) are gaining popularity, particularly among young and health-conscious consumers seeking to substitute animal meat in their diets. A study in the Canadian Journal of Cardiology examines the cardioprotective effects of PBMAs in Canadians.

Japan launches advanced Earth-observing satellite on 3rd flight of H3 rocket

Japan's new H3 rocket successfully launched the Advanced Land Observing Satellite-4 (ALOS-4 or DAICHI-4) from Tanegashima Space Center. The launch occurred at 11:06 p.m. EDT (0306 GMT on July 1), deploying ALOS-4 into low Earth orbit as scheduled, confirmed by Japan Aerospace Exploration Agency (JAXA) commentators.

Chinese rocket static-fire test results in unintended launch and huge explosion

In Hausjärvi, Finland, a test firing of Space Pioneer's Tianlong-3 rocket stage ended in a catastrophic failure and explosion on Sunday. The static-fire test at a facility in Henan province saw the rocket stage unexpectedly ignite, lift off, and then crash back to the ground, causing a significant explosion upon impact.
