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

open access: yesGalaxies, 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.

How to Conduct a Multi‐Domain Systematic (Literature) Review? Guidelines Using The Lotus Protocol

open access: yesPsychology &Marketing, Volume 43, Issue 6, Page 1297-1326, June 2026.
ABSTRACT Complex challenges increasingly demand multidisciplinary research across intersecting knowledge domains. However, existing systematic (literature) review protocols offer limited guidance and tend to confine scholars to single‐domain or single‐intersection reviews.

Electrically tunable and temperature compensated FBAR

open access: yes, 2005
This paper describes the design, fabrication and measurement of an electrically tunable, temperature compensated film bulk acoustic resonator (FBAR) that is formed by integrating FBAR with an electrostatic MEMS actuator. About 0.9% tuning (Δf ≅26 MHz) of

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

open access: yesAIP 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 ...

Auger Parameter Analysis for TiN and AlN Thin Films via Combined In Situ XPS and HAXPES

open access: yesSurface and Interface Analysis, Volume 58, Issue 6, Page 387-399, June 2026.
ABSTRACT Auger parameter analysis provides in‐depth information about electronic and chemical bonding properties of TiN and AlN thin films, which are relevant across a wide range of technologies. Meaningful interpretation and analysis of Auger parameter of these materials have been hindered due to, among other reasons, the absence of reliable ...

Approach to improve ZnO-based FBAR devices

open access: yes, 2007
Presented is a new technique to improve the resonance characteristics of film bulk acoustic-wave resonator (FBAR) devices. The FBAR devices were fabricated on multilayer Bragg reflectors into which ultra-thin chromium (Cr) adhesion layers were inserted ...

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

open access: yesMaterials 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.

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

open access: yesFish 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.

Film Bulk Acoustic-wave Resonator (FBAR) based infrared sensor

open access: yes, 2010
This paper described an infrared (IR) radiation sensor based on Film Bulk Acoustic-wave Resonator (FBAR). The resonant frequency of FBAR sensor downshifts linearly when there is IR (peak wavelength at 780nm) illumination on the device.

smsR: A seasonal assessment model for exploited stocks

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
We present a seasonal age‐based stock assessment model implemented in R, enabling stochastic estimation within the Template Model Builder framework for efficient parameter estimation and random effects modelling. Applied as the official model for several North Sea small pelagic stocks, the approach captures within‐year variation in growth, mortality ...
