Operating LISA as a Sagnac interferometer
, 2003 A phase-locking configuration for LISA is proposed that provides a significantly simpler mode of operation. The scheme provides one Sagnac signal readout inherently insensitive to laser frequency noise and optical bench motion for a non-rotating LISA ...

In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque
Advanced Science, EarlyView.In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...

Shifting tax burden to top income earners: what is the best way to reduce inequality?
Economics: Journal Articles, 2019 The authors analyze to what extent and how the tax burden should be shifted towards top income earners in order to reduce income inequality. Starting from Lambert and Aronson (Inequality decomposition analysis and the Gini coefficient revisited 1993) and

Wearable Metamaterials with Embodied Intelligence for Programmable Control of Human Limbs Tremor
Advanced Intelligent Systems, EarlyView.Resulting from alternating muscle contractions, tremors can severely limit human ability to perform everyday tasks like walking or talking, due to their disruptive nature. Medication and surgery may not always effectively address tremor control. A wearable device embodying programmable smart metamaterials with adaptable intelligence to meet the demand ...

Improved performance of d31-mode needle-actuating transducer with PMN-PT piezocrystal [PDF]
, 2018 Prototypes of a PZT-based ultrasound needle-actuating device have shown the ability to reduce needle penetration force and enhance needle visibility with color Doppler imaging during needle insertion for tissue biopsy and regional anesthesia. However, the demand for smaller, lighter devices and the need for high performance transducers have motivated ...
