The success of DeepSeek’s powerful artificial intelligence (AI) model R1 — that made the US stock market plummet when it was ...

Imagine you are developing antibodies—drugs precisely aimed at a target, for example a viral protein or onco-marker. You test a series of antibodies and find that some work, while others do not.

Heckman's (Ann Econ Soc Meas 4(5), 475-492, 1976; Econometrica 47, 153-161, 1979) sample selection model has been employed in three decades of applications of linear regression studies. This paper ...

Symage, a provider of physics-based, high-fidelity synthetic image data for training AI and computer vision models, will ...

A new artificial intelligence (AI) tool could make it much easier-and cheaper-for doctors and researchers to train medical imaging software, even when only a small number of patient scans are ...

Chinese scientists have constructed a numerical model to simulate the Martian atmosphere and thus assist the country's plans to collect rock samples from the Red Planet. The model replicates the ...
