People often see the same evidence but draw opposite conclusions, becoming increasingly polarized over time. Prior discussions of this puzzle have focused on the failure of Bayesian reasoning or on the possibility of non-common priors. By contrast, we offer a model of diverging opinions in a Bayesian environment with common priors. In our model, people hold different private information and dis...

Although hypersaline environments pose challenges to life because of the low water content (water activity), many such habitats appear to support eukaryotic microbes. This contribution presents brief reviews of our current knowledge on eukaryotes of water-column haloclines and brines from Deep Hypersaline Anoxic Basins (DHABs) of the Eastern Mediterranean, as well as shallow-water hypersaline m...

A dangerous border collision bifurcation has been defined as the dynamical instability that occurs when the basins of attraction of stable fixed points shrink to a set of zero measure as the parameter approaches the bifurcation value from either side. This results in almost all trajectories diverging off to infinity at the bifurcation point, despite the eigenvalues of the fixed points before an...

Neurodegenerative diseases (ND) are characterized by the progressive loss of specific neuronal populations with consequent deterioration of brain's function. While some ND have monogenic causes, the vast majority is sporadic. Accordingly, etiology varies greatly between these conditions; the pathogenesis, however, shares important common traits. Trophic deprivation, oxidative stress, accumulati...

Intense pressure and velocity oscillations, as well extensive air entrainment, make the investigation of hydraulic leap created in stilling basins very difficult. Its intricacy, coupled with real-world need for to dissipate energy, puts physical modelling front center. Despite basins' essential role engineering, bibliographic research has often focused primarily on more familiar case classical ...

Ogee spillway is the most important structure used to get rid of excess water during flood. Scouring phenomenon occurring in downstream region due high energy dissapation an envitable. This study aims reduce amount scour occurred at stilling basin ogee by using three dissipation blocks namely as baffle, triangle and stepped blocks. A new distribution was proposed for each type dissipated block,...

using of nanofluids and ducts with corrugated walls are both supposed to enhance heat transfer, by increasing the heat transfer fluid conductivity and the heat transfer area respectively. use of a diverging duct with a jet at inlet section may further increase heat transfer by creating recirculation zones inside the duct. in this work two-dimensional incompressible laminar flow of a nanofluid e...

This paper presents an experimental study of the transition from supercritical to subcritical flow at an abrupt drop. The paper reports a wide range of experimental conditions and the relevant regime charts. Long-term experimental results show that some flow configurations tend to behave quasiperiodically (i.e. oscillating flow patterns). The experimental results have direct implications on the...

Block ramps are ecofriendly drop structures, which ensure more stability in the downstream riverbed. The scouring stilling basin bed material generated by rapidly varied flow transition affects of ramp structure. In present study, a modified configuration is tested along with uniform conventional arrangements to check non-cohesive beds block ramps. Uniform horizontal configurations and sill arr...
