We study ionic current fluctuations in solid-state nanopores over a wide frequency range and present a complete description of the noise characteristics. At low frequencies (f ≲ 100 Hz) we observe ...

Functional diversity in a lipidome In their study, Schuhmacher et al. (5) use the tools of chemical biology to synthesize individual molecular species of DAG including stearyl arachidonyl DAG (SAG) as ...

The n-back task that was used as the training task, illustrated for a 2-back condition. The letters were presented auditorily at the same rate as the spatial material was presented visually.

Accurately controlled, very long wavelength moiré patterns are realized in small-twist-angle bilayer graphene, and studied using electron transport and scanning probe microscopy. We observe gaps in ...

A key challenge of ecosystem management is determining how to manage multiple ecosystem services across landscapes. Enhancing important provisioning ecosystem services, such as food and timber, often ...

Using a large-scale and representative survey, we examine who has adopted ChatGPT, how workers anticipate the technology will affect their jobs, and why some workers use it and others do not. We show ...

Formation of knots in mathematical self-avoiding random walks has been extensively studied (10 – 16). In the 1960s, Frisch and Wasserman (10) and Delbruck (11) conjectured that the probability of ...

The above theoretical works are concerned with TMD homobilayers with a small twist angle starting from the AA stacking, where every metal (M) or chalcogen (X) atom on the top layer is aligned with the ...

Control regions in the brain are thought to provide signals that configure the brain's moment-to-moment information processing. Previously, we identified regions that carried signals related to ...
