Counterflow superfluidity is an anomalous quantum phase that was predicted two decades ago in the context of a two-component Bose–Hubbard model. In this phase, although both components exhibit fluidity, their correlated counterflow currents cancel each
In the next Section 2, we provide an overview of the term mental model against the backdrop of a large body of research. In particular, we include educational psychology and neurology perspectives. 2. Theoretical Background on Mental Models When talking about cognition, the idea of mental ...
To guarantee the arrival of ultra-short pulses at the sample, laser pulse dispersion (pulse broadening), caused by the optical elements of the beam path, can be pre-compensated using, for instance, chirped mirrors (Figure 5) [119,120,121]. As aforementioned, the excitation volume of two-...

In order to clarify the large-scale coherent structure in a turbulent plane jet, the simultaneous measurement of the main streamwise and the cross-streamwise velocity at 9 points in the self-preserving region of a turbulent plane jet has been preformed by an array of X-type hot wire probes....

Today air travel is far safer than driving a car on a busy motor-way. But still there is a danger that grows every year. Airliners get larger and larger. Some airplanes can carry over 300 passengers. And the air itself becomes more and more crowded. If one large airliner struck into an...
but details as basic as what it looks like beneath all that ice have largely remained a mystery.Now,Earther reports that a team of scientists from Denmark,Norway,the Netherlands,and the UK has published the most detailed data yet on the continent's subglacial topography (冰川...
