It's time to rethink the claim that retention does more harm than good — studies and real life examples show it can improve education outcomes.

Abstract: The design and a proof-of-principle experiment on a gyrotron backward-wave oscillator (gyro-BWO) with broadband frequency tuning are discussed. The considered gyro-BWO uses a recently ...

Abstract: In this study, we demonstrate the relationship between the absorbing frequency and the quasi-bound states in the continuum (quasi-BIC) frequency by employing the coupled-mode theory (CMT) ...

The construction of digital infrastructure, exemplified by China's "Broadband China" policy, has the unintended consequence of increasing corporate borrowing costs. Utilising a quasi-experimental ...
