6a, b, we found that neutral items encoded during high-valence music (i.e., more positive emotions) were statistically significantly better remembered as a function of increasing arousal (1 SD above the mean = 0.073; β = 0.08, p < 0.001, 95% CI = [0.03, 0.14])...
In this section we discuss three issues in the peer-reviewed publication process which have arisen during the COVID-19 pandemic: fast-track publication, conflicts of interest and lack of data sharing. We highlight the increasing retraction rate of COVID-19 preprints and peer-reviewed articles, ...
In order to study the topological features and the microscopic origin of the transition, we have constructed a tight-binding (TB) Hamiltonian as a function of uniaxial pressure. It comprises the s and p orbitals of the two Sn atoms in the unit cell and the d orbitals of the Ba atom (th...
From the simulation results, it can be known that by increasing the subsidy, the government can stimulate the enterprises to a certain extent and increase their willingness to participate in the cross-border e-commerce B2B export trading. When the government subsidy is 0.3, the operation cost is...
A novel experiment has been devised shedding new light on the phenomenon of unipolar induction, also known as “Faraday’s Paradox”. This is a topic which continues to fascinate scientists and engineers with much debate continuing to this day. In partic
