Since the discovery of superconductivity in twisted bilayer graphene in 2018, moiré superlattices have emerged as an important platform for controlling electronic states in two-dimensional (2D) ...
Z.C. and P.G.W. were supported both by the Bullard-Welch Chair at Rice University, grant C-0016, and by the Center for Theoretical Biological Physics sponsored by NSF grant PHY- 2019745. Reviewers: ...
I wish to gratefully thank the Editorial Board Member Mary Power for useful suggestions to improve the accessibility of this commentary for a general reader. K. Zhao et al., Variability in alluvial ...
Disputes are central to scientific progress, but their resolution can be difficult. Adversarial collaboration offers a powerful but underexplored method for addressing scientific debate. We offer ...
As the central kinase in antiviral innate immunity, the activation of TANK-binding kinase 1 (TBK1) must be tightly controlled. However, how host metabolic pathways directly regulate TBK1 activity ...

Edge detection is a fundamental tool in image processing, computing, and machine vision. Compared with digital processes, optical analog approaches show enormous advantages owing to its intrinsic ...
We present a systematic study of the Raman spectra of optical phonons in graphene monolayers under tunable uniaxial tensile stress. Both the G and 2D bands exhibit significant red shifts. The G band ...
The Democracy Index finding holds up best. Its negative direct effect on offensive VEI (we use β for SDM coefficients throughout) survives spatial adjustment in every bivariate specification (Table 1) ...
Future drought is projected to occur under warmer temperature conditions as climate change progresses, referred to here as global-change-type drought, yet quantitative assessments of the triggers and ...
The fullerenes are the first “free-standing” elemental hollow cages identified by spectroscopy experiments and synthesized in the bulk. Here, we report experimental and theoretical evidence of hollow ...
