Over the past decade, the dominance of deep learning has prevailed across various domains of artificial intelligence, including natural language processing, computer vision, and biomedical signal processing. While there have been remarkable improvements in model accuracy, deploying these models on lightweight devices, such as mobile phones and microcontrollers, is constrained by limited resources.

Synthetic Data for Deep Learning in Computer Vision & Medical Imaging: A Means to Reduce Data Bias ACM Comput. Surv. (IF 16.6) Pub Date : 2024-05-09 Anthony Paproki, Olivier Salvado, Clinton Fookes
Deep-learning (DL) performs well in computer-vision and medical-imaging automated decision-making applications. A bottleneck of DL stems from the large amount of labelled data required to train accurate models that generalise well. Data scarcity and imbalance are common problems in imaging applications that can lead DL models towards biased decision making. A solution to this problem is synthetic data

Rhizobia–diatom symbiosis fixes missing nitrogen in the ocean Nature (IF 64.8) Pub Date : 2024-05-09 Bernhard Tschitschko, Mertcan Esti, Miriam Philippi, Abiel T.

Nitrogen (N2) fixation in oligotrophic surface waters is the main source of new nitrogen (N) to the ocean1 and plays a key role in fueling the biological carbon pump2. Oceanic N2 fixation is almost exclusively attributed to cyanobacteria, even though genes encoding nitrogenase, the enzyme fixing N2 into ammonia, are widespread among marine bacteria and archaea3-5. Little is known about these non-cyanobacterial

Structural mechanism of angiogenin activation by the ribosome Nature (IF 64.8) Pub Date : 2024-05-08 Anna B. Loveland, Cha San Koh, Robin Ganesan, Allan Jacobson, Andrei A. Korostelev
Angiogenin, an RNase A-family protein, promotes angiogenesis and has been implicated in cancer, neurodegenerative diseases, and epigenetic inheritance 1-10. Upon activation during cellular stress, angiogenin cleaves tRNAs at the anticodon loop, resulting in translation repression 11-15. The catalytic activity of isolated angiogenin, however, is very low, and the mechanisms of the enzyme activation

The properties of polycrystalline materials are often dominated by defects, and two-dimensional (2D) crystals can even be divided and disrupted by a line defect1-3. In contrast, 2D crystals are often required to be processed into films, which are inevitably polycrystalline and contain numerous grain boundaries, and therefore are brittle and fragile, hindering application in flexible electronics, optoelectronics
