On some rotational flows of non-integer order rate type fluids with shear stress on the boundary
Ain Shams Engineering Journal, 2018 This article presents rotational flows of some rate type fluids with non-integer order derivatives. The fluid fills an infinite straight circular cylinder and its motion is generated by a time dependent torsion, applied to the surface of the cylinder. As

The Discrete Dantzig Selector: Estimating Sparse Linear Models via Mixed Integer Linear Optimization
, 2017 We propose a novel high-dimensional linear regression estimator: the Discrete Dantzig Selector, which minimizes the number of nonzero regression coefficients subject to a budget on the maximal absolute correlation between the features and residuals ...

Integer solutions of by2 + pn = x3
Journal of Number Theory, 1975 AbstractThe equation by2 + pn = x3 is regarded as a diophantine equation in the integer variables x, y, and n. Solutions of such equations are explicitly constructed for a large class of parameters b and p. For example, the five families of solutions to the equation y2 + 11n = x3 are given. Indeed, the conditions on b and p and the proofs can be viewed

Advanced Materials Interfaces, EarlyView.Although electrochemical scanning tunneling microscopy provides atomic‐scale access to electrified interfaces, quantitative in situ and operando investigations suffer from drift‐induced distortions. This work introduces the Lattice Fourier Analyzer (LFA), which employs substrate‐anchored affine drift correction in reciprocal space to recover precise ...

Complete Solutions to Mixed Integer Programming
American Journal of Computational Mathematics, 2013 This paper considers a new canonical duality theory for solving mixed integer quadratic programming problem. It shows that this well-known NP-hard problem can be converted into concave maximization dual problems without duality gap. And the dual problems can be solved, under certain conditions, by polynomial algorithms.

Topological Point Defects in SmC* Liquid Crystals Under Mechanical Disturbance
Advanced Materials Interfaces, EarlyView.Tangetial air jet shear inducess island formation and nucleates topological point defects in uniform SmC films. Island bounded by edge dislocation loops shrink and transform into isolated point defects under continued shear. Mechanical perturbatio provides a controllable route for defect engineering in smectric liquid crystal thin films.
