Organic solar cells (OSCs) based on nonfullerene acceptors (NFAs) have made significant
breakthrough in their device performance, now achieving a power conversion efficiency of≈ …

While FPGAs have seen prior use in database systems, in recent years interest in using
FPGA to accelerate databases has declined in both industry and academia for the following …

The aim of this systematic review was to assess evidence from randomized controlled trials
(RCTs) on the effectiveness and safety of acupuncture and electroacupuncture in patients …

The mechanism of high-temperature superconductivity in the newly discovered iron-based
superconductors is unresolved. We use spectroscopic imaging–scanning tunneling …

The randomness of dopant atom distributions in cuprate high–critical temperature
superconductors has long been suspected to cause nanoscale electronic disorder. In the …

The doping dependence of nanoscale electronic structure in superconducting Bi 2 Sr 2 Ca
Cu 2 O 8+ δ is studied by scanning tunneling microscopy. At all dopings, the low energy …

Formation of electron pairs is essential to superconductivity. For conventional
superconductors, tunnelling spectroscopy has established that pairing is mediated by …

The antiferromagnetic ground state of copper oxide Mott insulators is achieved by localizing
an electron at each copper atom in real space (r-space). Removing a small fraction of these …

Direct volume rendering is a key technology for visualizing large 3D data sets from scientific
or medical applications. Transfer functions are particularly important to the quality of direct …

We have measured 3D face geometry, skin reflectance, and subsurface scattering using
custom-built devices for 149 subjects of varying age, gender, and race. We developed a …
