Effect of impeller inlet diameter on saddle-shaped positive slope and non-uniform flow patterns at low flow rates of a mixed-flow pump

open access: yesEngineering Applications of Computational Fluid Mechanics, 2022
Most mixed-flow pumps obtain a saddle-like Q-P curve with a backflow, owing to the increased incidence angle at low flow rates. The backflow was developed near the shroud and followed downstream again at its end to form a recirculating flow. The rotating

Searching the solution landscape by generalized high-index saddle dynamics [PDF]

open access: yesScience China Mathematics, 2020
We introduce a generalized numerical algorithm to construct the solution landscape, which is a pathway map consisting of all stationary points and their connections.

Homoclinic saddle to saddle-focus transitions in 4D systems [PDF]

open access: yesNonlinearity, 2019
A saddle to saddle-focus homoclinic transition when the stable leading eigenspace is 3-dimensional (called the 3DL bifurcation) is analyzed. Here a pair of complex eigenvalues and a real eigenvalue exchange their position relative to the imaginary axis, giving rise to a 3-dimensional stable leading eigenspace.

A tale of two saddles

open access: yesJournal of High Energy Physics, 2022
Abstract We find a new on-shell replica wormhole in a computation of the generating functional of JT gravity coupled to matter. We show that this saddle has lower action than the disconnected one, and that it is stable under restriction to real Lorentzian sections, but can be unstable otherwise.

Subgroup-Specific Diagnostic, Prognostic, and Predictive Markers Influencing Pediatric Medulloblastoma Treatment

open access: yesDiagnostics, 2021
Medulloblastoma (MB) is the most common malignant central nervous system tumor in pediatric patients. Mainstay of therapy remains surgical resection followed by craniospinal radiation and chemotherapy, although limitations to this therapy are applied in ...

Distributed saddle point problems: lower bounds, near-optimal and robust algorithms* [PDF]

open access: yesOptimization Methods and Software, 2020
This paper focuses on the distributed optimization of stochastic saddle point problems. The first part of the paper is devoted to lower bounds for the centralized and decentralized distributed methods for smooth (strongly) convex-(strongly) concave ...

Comparative Analysis of the Lacquer Coating of Archaeological Objects of the Xiongnu and Turkish Periods from the Burial Mounds of Transbaikalya and Tuva

open access: yesАрхеология евразийских степей, 2021
It has been archaeologically proven that the representatives of the clan nobility of Sayan-Altai tribes used lacquer products in everyday life as early as in the Scythian period. In later complexes, lacquer objects, as well as objects coated with lacquer,
