Analytic solutions of a two-fluid hydrodynamic model
Mathematical Modelling and Analysis, 2021 We investigate a one dimensional flow described with the non-compressible coupled Euler and non-compressible Navier-Stokes equations in the Cartesian coordinate system.

Rarefaction wave in relativistic steady magnetohydrodynamic flows [PDF]
, 2014 We construct and analyze a model of the relativistic steady-state magnetohydrodynamic (MHD) rarefaction that is induced when a planar symmetric flow (with one ignorable Cartesian coordinate) propagates under a steep drop of the external pressure profile.

Heisenberg-type higher order symmetries of superintegrable systems separable in Cartesian coordinates [PDF]
Nonlinearity, 2017 Heisenberg-type higher order symmetries are studied for both classical and quantum mechanical systems separable in cartesian coordinates. A few particular cases of this type of superintegrable systems were already considered in the literature, but here they are characterized in full generality together with their integrability properties. Some of these

Bilateral symmetry detection on the basis of Scale Invariant Feature Transform. [PDF]
PLoS ONE, 2014 The automatic detection of bilateral symmetry is a challenging task in computer vision and pattern recognition. This paper presents an approach for the detection of bilateral symmetry in digital single object images.

A novel laser-based stereotactic localization device for intracranial mass resection
Brain Hemorrhages, 2021 Unfortunately, both frame-based and frameless stereotactic neuronavigation platforms are far from ubiquitous in global neurosurgery, and many facilities lack accurate localization technology to ensure the safety of intracranial surgery such as cerebral ...

Advanced Engineering Materials, EarlyView.Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

The conservation equations for multicomponent gas mixtures in arbitrary coordinate systems [PDF]
, 1958 The conservation equations for multicomponent reacting gas mixtures are generally given only in Cartesian or orthogonal curvilinear coordinate systems. Actually, the conservation equations are easily expressed in an arbitrary coordinate system.

Advanced Functional Materials, EarlyView.This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.
