Constriction for sets of probabilities [PDF]
arXiv, 2023 Given a set of probability measures $\mathcal{P}$ representing an agent's knowledge on the elements of a sigma-algebra $\mathcal{F}$, we can compute upper and lower bounds for the probability of any event $A\in\mathcal{F}$ of interest. A procedure generating a new assessment of beliefs is said to constrict $A$ if the bounds on the probability of $A ...

Transport through constricted quantum Hall edge systems: beyond the quantum point contact [PDF]
Phys. Rev. B 77, 035331 (2008), 2007 Motivated by surprises in recent experimental findings, we study transport in a model of a quantum Hall edge system with a gate-voltage controlled constriction. A finite backscattered current at finite edge-bias is explained from a Landauer-Buttiker analysis as arising from the splitting of edge current caused by the difference in the filling fractions

A mechanical model reveals that non-axisymmetric buckling lowers the energy barrier associated with membrane neck constriction [PDF]
, 2019 Membrane neck formation is essential for scission, which, as recent experiments on tubules have demonstrated, can be location dependent. The diversity of biological machinery that can constrict a neck such as dynamin, actin, ESCRTs and BAR proteins, and the range of forces and deflection over which they operate, suggest that the constriction process is

Lattice Expansion in Seamless Bi layer Graphene Constrictions at High Bias [PDF]
Nano Lett. 2012, 12, 4455, 2012 Our understanding of sp2 carbon nanostructures is still emerging and is important for the development of high performance all carbon devices. For example, in terms of the structural behavior of graphene or bi-layer graphene at high bias, little to nothing is known. To this end we investigated bi-layer graphene constrictions with closed edges (seamless)

MicroRNA-1 downregulation increases connexin 43 displacement and induces ventricular tachyarrhythmias in rodent hypertrophic hearts. [PDF]
PLoS ONE, 2013 Downregulation of the muscle-specific microRNA-1 (miR-1) mediates the induction of pathologic cardiac hypertrophy. Dysfunction of the gap junction protein connexin 43 (Cx43), an established miR-1 target, during cardiac hypertrophy leads to ventricular ...

Differences in the effects of turns and constrictions on the resistive response in current-biased superconducting wire after single photon absorption [PDF]
Supercond. Sci. Technol. 26 (2013) 075008, 2013 We study how turns and constrictions affect the resistive response of the superconducting wire after instant in time and local in space heating, which models the absorption of the single photon by the wire. We find that the presence of constriction favors detection of photons of various energies but the presence of turn increases only ability to detect

Experimental Validation of Simplified Free Jet Turbulence Models Applied to the Vocal Tract [PDF]
arXiv, 2008 Sound production due to turbulence is widely shown to be an important phenomenon involved in a.o. fricatives, singing, whispering and speech pathologies. In spite of its relevance turbulent flow is not considered in classical physical speech production models mostly dealing with voiced sound production. The current study presents preliminary results of
