As transit agencies scramble to adjust to the new transport landscape of mobility services, this has become an important question.This study focuses on New York’s commuter vans (also Your Heart known as “dollar vans„), private vans that have operated along
With the development of nanotechnology, bioengineering and biology, it is envisioned that biological nanomachines may flourish in assorted valuable applications considering their unique characteristics including energy efficiency, bio-compatibility and extremely small scale.However, current biological nanomachines are only able to perform simple ta
Abstract We consider the positivity bounds for WIMP scalar dark matter with effective Higgs-portal couplings up to dimension-8 operators.Taking the superposed states for Standard Model Higgs and scalar dark matter, we show that the part of the parameter space for the effective couplings, otherwise unconstrained by phenomenological bounds, is ruled
