This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

Reverberation Time and Power Model in Indoor Wireless Scenarios [PDF]
A novel, room-electromagnetics-theory-based model for reverberation time, path gain and Power Delay Profile (PDP) is proposed. Unlike the traditional models describing only the reflections, the new model takes not only reflections at boundaries, but also

Modeling plate and spring reverberation using a DSP-informed deep neural network [PDF]
Plate and spring reverberators are electromechanical systems first used and researched as means to substitute real room reverberation. Nowadays they are often used in music production for aesthetic reasons due to their particular sonic characteristics.

This work demonstrates an interphase strain engineering strategy to regulate capacitive energy storage performance in high‐entropy oxide thin films. Through introducing pyrochlore nanocolumns, the polarization response of perovskite unit cells is strengthened, yielding recoverable energy densities up to 93 J cm−3 with an efficiency of 83% under ...

The Acoustics of the Double Elliptical Vault of the Royal Palace of Caserta (Italy)
This work investigates the acoustic characteristics of the double elliptical vault, which overlooks the Grand Staircase of the Royal Palace of Caserta (Italy). The Royal Palace was built by the architect Luigi Vanvitelli in the Seventeenth Century and it

A series of ACHPES‐based hydrogels are developed and realizing multiple functions like anti‐fouling properties, alkali‐induced color/fluorescence‐changing ability and strain sensing. Furthermore, the hydrogels show excellent anti‐freezing performance, whose optical, mechanical and electrical properties remain stable at −47.3 °C.

SRMR variants for improved blind room acoustics characterization [PDF]
Reverberation, especially in large rooms, severely degrades speech recognition performance and speech intelligibility. Since direct measurement of room characteristics is usually not possible, blind estimation of reverberation-related metrics such as the reverberation time (RT) and the direct-to-reverberant energy ratio (DRR) can be valuable ...

This study reports a novel strategy for preparing a biocompatible adhesive hydrogel crosslinked with a muscle tissue‐derived extracellular matrix (MEM) for in situ muscle regeneration. As a natural crosslinker, MEM not only mediates combinatorial polymer networks but also stimulates satellite cells to induce a cell‐free therapeutic solution.

Comments on “Reverberation Radius in Real Rooms” [PDF]
The goal of this letter is to comment on the article "Reverberation Radius in Real Rooms" by Mijić and Mašović (2010). Mijić and Mašović measured critical distance and reverberation time in four different size rooms from 125 Hz to 4 kHz octave bands ...
