A Pump‐Free, Hydraulic‐Amplification Oscillatory Microfluidic Device for Continuous Particle and Cell Manipulation

open access: yesAdvanced Science, EarlyView.
This study demonstrates a pump‐free, hydraulic‐amplification oscillatory microfluidic device, which generates oscillatory flows by deforming flexible microchannels through reciprocating finger pressing. The mechanism of elasto‐inertial focusing in the oscillatory flows is revealed, and early detection of drug‐treated platelet aggregates and rapid cell ...

Elliptical Lorenz curves

Journal of Econometrics, 1989
A family of elliptic Lorenz curves is proposed for fitting grouped income data. The associated distribution and density functions are displayed together with the Gini indices. Estimation procedures are discussed. Comparisons are made with alternative models using Australian 1967--68 income data.

Elliptic-Curve Cryptography

2020
Elliptic-curve cryptography (ECC) represents a public-key cryptography approach. It is based on the algebraic structure of elliptic curves over finite fields. ECC can be used in cryptography applications and primitives, such as key agreement, digital signature, and pseudo-random generators.
