Lock–release laboratory experiments are performed to examine saline and particleladen flows down a slope into both constant-density and linearly stratified ambients. Both hypopycnal (surface-propagating) currents and hyperpycnal (turbidity) currents are examined, with the focus being upon the influence of ambient stratification on turbidity currents. Measurements are made of the along-slope fro...

The information about the distance of separation between two point targets that is contained in scattering data is explored in the context of the scalar Helmholtz operator via the Fisher information and associated Cramér-Rao bound (CRB) relevant to unbiased target separation estimation. The CRB results are obtained for the exact multiple scattering model and, for reference, also for the single ...

Switchable solvents are changing properties when exposed to an external stimulus. As example, for thermomorphic multiphasic system (TMS), temperature changes can induce phase separations. Aqueous systems presented here formulated with a carboxylic acid (weak acid) and amphiphilic tertiary amine base). They show thermo-switchable hydrophobicity after separation, the weak base mainly found in org...

Chiroptical signals (generally very weak) play significant roles in chiral discrimination that bring great benefits biochemistry, pharmacy, chemical, and so on. But, high-precise chiroptical detection is still a challenge. In this paper, measurement of optical rotatory dispersion (ORD) based on weak value amplification (WVA) presented. We proposed ORD method with parameter separation: by introd...
