Breaking the lowest oxygen abundance record.

New results achieved by combining big data captured by the Subaru Telescope and the power of machine learning have discovered a galaxy with an extremely low oxygen abundance of 1.6% solar abundance, breaking the previous record of the lowest oxygen abundance. The measured oxygen abundance suggests that most of the stars in this galaxy formed very recently.

(WTXL) — History could be made right here in the Big Bend this weekend.

For the first time in 45 years, a NASA spacecraft with two American Astronauts on board will splash down off the coast of Florida.

The exact location of where the SpaceX Crew Dragon spacecraft will splashdown hasn’t been announced yet.

Even in a dual-socket AMD EPYC Rome/Milan server and 4 x MI100 PCIe-based accelerators, we’re looking at 128GB of HBM memory on offer with 4.9TB/sec of bandwidth. We see a drop down to 136 TFLOPs here as well.

We are looking at the purported AMD Radeon Instinct MI100 accelerator being around 13% faster in FP32 compute performance over NVIDIA’s new Ampere A100 accelerator. The performance to value ratio is much better, with the MI100 being 2.4x better value over a V100S setup, and 50% better value over Ampere A100.

Admittedly, the project is a little dangerous—not because of a few little fusion reactions but because of the very flammable gas and voltages high enough to instantly kill you.

Do you know what natural ionising radiation is? Where can you find natural resources of radiation? What are the levels of natural sources of radiation in Europe? Do you know the pathways of ionising radiation? Natural radionuclides, both terrestrial and cosmogenic, migrate in the environment through different pathways: air, water, rock, soil and the food chain. Radionuclides may then enter the.

Human body through ingestion (food and drinking water) and inhalation giving, so-called, internal exposure. External exposure is due to cosmic radiation and radiation from terrestrial radionuclides present in soil, rock and building materials. The first ever ‘European atlas of natural radiation’ uses informative texts, stunning photographs and striking maps to answer and explain these and other questions.

Observations of the X8.2 solar flare, which happened on 2017 September 10, could spatially resolve the distribution of the energetic electrons along the reconnection current sheet. More than 99% of them are concentrated at the bottom of the current sheet, not at the reconnection X point.

Obtaining transparent glasses made of functional coordination polymers (CPs) represents a tremendous opportunity for optical applications. In this context, the first transparent and red-emissive glasses of gold thiolate CPs have been obtained by simply applying mechanical pressure to amorphous powders of CPs.

Statistical studies of the motions of millions of stars may reveal the subtle imprint of dark matter.

We have created a new architected material, which is both highly deformable and ultra‐resistant to dynamic point loads. The bio-inspired metallic cellular structure (with an internal grid of large ceramic segments) is non-cuttable by an angle grinder and a power drill, and it has only 15% steel density. Our architecture derives its extreme hardness from the local resonance between the embedded ceramics in a flexible cellular matrix and the attacking tool, which produces high-frequency vibrations at the interface. The incomplete consolidation of the ceramic grains during the manufacturing also promoted fragmentation of the ceramic spheres into micron-size particulate matter, which provided an abrasive interface with increasing resistance at higher loading rates. The contrast between the ceramic segments and cellular material was also effective against a waterjet cutter because the convex geometry of the ceramic spheres widened the waterjet and reduced its velocity by two orders of magnitude. Shifting the design paradigm from static resistance to dynamic interactions between the material phases and the applied load could inspire novel, metamorphic materials with pre-programmed mechanisms across different length scales.
