Scanners for loose papers have become so commonplace that almost every printer includes one, but book scanners have remained frustratingly rare for non-librarians and archivists. [Brad Mattson] ...

Here we report the arrangement of a nanostructure array in microchannels to control equilibrium and nonequilibrium transports of macromolecules. The direct observation and separation of macromolecules ...

This allows the implementation of any logic to handle the actual servo control. For example, you can make use of the standard Servo library for simple setups or add logic to control servos via PWM ...

This paper proposes a high-fidelity scattering control method for phased array based on analytical theory, which is applicable to radar cross section (RCS) reduction. Through theoretical derivation, ...

Accurate control of complex excitation of array elements is key to ensure spatial discrimination capability of millimeter-wave (mmWave) phased array, e.g., beamforming to target signal directions and ...

The Centers for Disease Control and Prevention will no longer recommend routine Covid shots for healthy children and pregnant women, Health and Human Services Secretary Robert F. Kennedy Jr ...

We report an approach for growing aligned ZnO nanowire arrays with a high degree control over size, orientation, dimensionality, uniformity, and possibly shape. Our method combines e-beam lithography ...
