Long-term results of catheter radiofrequency ablation of cavotricuspid isthmus in patients with typical atrial flutter and diabetes mellitus type 2

open access: yesRUDN Journal of Medicine, 2016
Aim - to evaluate the effectiveness of radiofrequency ablation cavotricuspid of the isthmus in patients with diabetes mellitus (DM) type 2, and typical atrial flutter, as well as to identify the factors of recurrence of atrial flutter after the procedure.

Electroluminescent Liquid Metal Marbles for Reconfigurable Multi‐Color Display

open access: yesAdvanced Science, EarlyView.
Phosphor‐coated liquid metal marbles offer a reconfigurable electroluminescent multicolor display platform, where the plasma discharge across marble arrays generates colored light. By tuning the mixing ratio of different types of primary‐color‐emitting phosphor particles, full‐spectrum additive color mixing is achieved.

Comparison of analytical and wind-tunnel results for flutter and gust response of a transport wing with active controls [PDF]

open access: yes
Two flutter suppression control laws wre designed and tested on a low speed aeroelastic model of a DC-10 derivative wing. Both control laws demontrated increases in flutter speed in excess of 25 percent above the passive wing flutter speed.

A Large Area Hybrid Phototransistor Platform with Large Detectivity and Fast Response to NIR Light

open access: yesAdvanced Electronic Materials, EarlyView.
A geometrically engineered tri‐channel architecture with a 4‐mm2 large sensing area is implemented in a hybrid multilayer phototransistor. The side channels electrically coupled to the 4 mm2 large central area enable efficient and fast detection of small perturbations of the charge density at the sensing surface, produced by a near‐infrared ...

Experimental Methods Applied in a Study of Stall Flutter in an Axial Flow Fan

open access: yesShock and Vibration, 2004
Flutter testing is an integral part of aircraft gas turbine engine development. In typical flutter testing blade mounted sensors in the form of strain gages and casing mounted sensors in the form of light probes (NSMS) are used.
