A neutron powder diffraction (NPD) and differential scanning calorimetry(DSC) study indicates that Cs 2B 12H 12 undergoes a second-order phase transition near
A study was conducted to evaluate the potential for using a linear relationship between the power input to a residential water heater and the output of thermal
Dear Password, Its time for you to retire. Youve served us well, but the reality is that youre woefully outdated and fundamentally insecure. Moreover, our

A 70 micrometer pinhole and an X-ray CCD camera in single photon counting mode were used to obtain spatially and spectral resolved images of an electron
We propose and implement verification methods for measurements of noise parameters of amplifiers and transistors. Because the verification rests on the
We propose and demonstrate a novel technique to measure the vibration sensitivity of two-port fiber-based optical components. It uses a common-arm counter
The National Institute of Standards and Technology (NIST) is the leader in the development of computer-based fire models that simulate the movement of fire
