The two astronauts were expecting a short flight on NASA’s new Starliner spacecraft. They’d fly to the International Space Station, or ISS (see “Space Station”). Successfully docking there would certify… Audio Spanish People Dreaming of a Cure August 15, 2024 When Heman Bekele ...
Surface chemistry of gunshot residue (GSR) particles by time of flight secondary ion mass spectrometry (ToF SIMS) - Complement to electron microscopy (SEM/... Time-of-flight secondary ion mass spectrometry (ToF SIMS) is used to complement scanning electron microscopy/ energydispersive X-ray spectr...
Real-time imaging of temporal focusing of single ultrashort laser pulses is of great significance in exploring the physics of the space–time duality and finding diverse applications. The drastic changes in the width and intensity of an ultrashort laser pulse during temporal focusing impose a ...
The method is sensitive to small changes in core level positions. Fast measurements at low pump fluences are enabled by the use of a pump laser at a lower repetition frequency than the repetition frequency of the X-ray pulses used to probe the core level electrons: Through the use of a ...
While I don’t suggest waiting until late at night, even if you call yourself a night owl, I do acknowledge that everyone isn’t capable of solving the world’s problems — or even chemistry — at 8 AM. Make a plan Using your class schedule as the foundation, create a time management...
This work presents in vitro and in vivo aroma release analysis of three espresso coffees carried out by PTR-ToF-MS headspace and nosespace analysis, respectively. The products were C. arabica coffees prepared using an espresso coffee machine: a low-caffe
A new type of partially delay-dependent controller (PDDC) is designed so that the resulting closed-loop systems are finite-time bounded and satisfy a given 𝐻∞ disturbance attenuation level. The PDDC contains both non-time-delay and time-delay states, though not happening at the same time...
A good example of where it is explicitly considered is a late stage financing where a company specifically seeks out “passive capital.” In that scenario, both sides are choosing to largely remove the time equation from the investment analysis and simply treat the deal as an exchange of capita...
