This paper provides a pair similarity optimization viewpoint on deep feature learning, aiming
to maximize the within-class similarity s_p and minimize the between-class similarity s_n. …

Two-dimensional atomic crystals are extensively studied in recent years due to their exciting
physics and device applications. However, a molecular counterpart, with scalable …

Air pollution may increase risk of Alzheimer’s disease and related dementias (ADRD) in the
US, but the extent of this relationship is unclear. Here, we constructed two national US …

Dielectric materials with both high recoverable energy-storage density W rec and efficiency
η have attracted a lot of attention in recent years. Permittivity plays a crucial role in …

Colorectal cancer (CRC) is one of the most common malignancies worldwide. China, Europe
and northern America account for more than half of the new CRC cases and associated …

Hitherto, Pt-based catalysts still are state of the art for oxygen reduction reaction (ORR) and
hydrogen evolution reaction (HER), but high dosage, low atom-utilization efficiency, and …

Pancreatic cancer is a malignancy with poor prognosis and high mortality. The recent
increase in pancreatic cancer incidence and mortality has resulted in an increased number of …

The mammalian brain is a complex organ comprising neurons, glia, and more than 1 × 10
14 synapses. Neurons are a heterogeneous group of electrically active cells, which form the …

Postmeiotic spermatids use a unique strategy to coordinate gene expression with
morphological transformation, in which transcription and translation take place at separate …

As one of the energy-efficient alternatives of conventional neural networks (CNNs), spiking
neural networks (SNNs) have gained more and more interest recently. To train the deep …
