Assessing the Progress of Stock Rebuilding in the Northeast Atlantic Against Levels That Can Produce Maximum Sustainable Yield

Fish and Fisheries, Volume 27, Issue 3, Page 519-536, May 2026.
ABSTRACT Rebuilding fish stocks to levels above which they produce Maximum Sustainable Yield (MSY) is a management aim for all European commercially exploited stocks. Progress is typically monitored against the fishing mortality that produces MSY in the long term (FMSY), however, the corresponding biomass target (BMSY) is rarely evaluated nor reported.

The Inner Regions of Disk Galaxies: A Constant Baryonic Fraction?

Galaxies, 2014
For disk galaxies (spirals and irregulars), the inner circular-velocity gradient dRV0 (inner steepness of the rotation curve) correlates with the central surface brightness ∑*,0 with a slope of ~0.5.

Super-high sensitivity FBAR temperature sensor based on size effect of Ti insertion layer

Materials Research Express, 2021
The temperature sensitivity is one of the critical parameters for the thin film bulk acoustic resonator (FBAR) based temperature sensors. In this work, FBARs with Au/Fe _0.8 Ga _0.2 /Ti/AlN/Mo structure are developed.

MEMS‐Based Magnetoelectric Antennas for Wireless Power Transmission in Brain‐Implantable Devices

Advanced Materials Technologies, Volume 11, Issue 3, 5 February 2026.
Magnetoelectric (ME) antennas allow the minimization of the invasiveness of brain implantable devices, via powering wirelessly systems able to actuate neural tissue. In order to achieve the necessary power efficiency transmission, the choice of the materials and the system assembly is vital.

Dependence of Barred Galaxy Fraction on Galaxy Properties and Environment

, 2011
We investigate the dependence of occurrence of bars in galaxies on galaxy properties and environment. We use a volume-limited sample of 33,391 galaxies brighter than $M_{r}=-19.5+5$log$h$ at $0.02\le z\le0.05489$, drawn from the SDSS DR 7.

Fabrication of Bulk Acoustic Wave Resonator with Multilayer Graphene Electrode

physica status solidi (b), Volume 262, Issue 12, December 2025.
Herein, multilayer graphene structures are grown on the silicon substrate for the fabrication of the bulk acoustic wave resonator device. The result reveals that both methods can be used to replace the Bragg reflector. Two bulk acoustic wave resonator (BAW) devices with multilayer graphene as bottom electrodes are fabricated using the chemical vapor ...

Effects of mode couplings on the vibration characteristics of partially electroded thin-film bulk acoustic wave resonators

AIP Advances, 2019
Mode coupling vibrations in thin-film bulk acoustic wave resonators (FBARs) were systematically analyzed in the series of our work. Previously, the two-dimensional theory of multi-layered FBAR plate has been established and used for the analysis of both ...

Optimized test PCBs for SAW / FBAR RF filters [PDF]

IEEE Ultrasonics Symposium, 2004, 2005
The characterization of the precise performance of packaged SAW RF filters is an extremely difficult task, due to their high complexity and high performance. If printed circuit boards (PCB) for testing the filters are not carefully designed, they presumably show parasitic effects influencing the measurement results of the overall system consisting of ...

Epitaxial and Fiber‐Textured Stacks of Al0.7Sc0.3N/Mo/AlN Prepared by Magnetron Sputter Epitaxy for Bulk Acoustic Wave Devices: A Comparison using High Overtone Bulk Acoustic Wave Resonator

physica status solidi (a), Volume 222, Issue 16, August 2025.
The study compares high overtone bulk acoustic wave resonators (HBAR) using fiber‐textured and epitaxial Al0.7Sc0.3N/Mo/AlN stacks on Si(111). HBAR fabricated using an epitaxial stack show superior performance, with 25% higher figure of merit due to improved crystal quality and piezoelectric response.

The Rise of Refractory Transition‐Metal Nitride Films for Advanced Electronics and Plasmonics

Advanced Materials Interfaces, Volume 12, Issue 12, June 23, 2025.
Transition‐metal nitrides (TMNs) are exceptional materials with high stability, biocompatibility, and semiconductor integration, which have been extensively employed in various fields. However, the epitaxial growth of TMN films remains a challenge. The absence of high‐quality TMNs limits the understanding of their condensed matter physics and hinders ...
