Beamforming for Direction-of-Arrival (DOA) Estimation-A Survey

open access: yesInternational Journal of Computer Applications, 2013
Direction-of-Arrival (DOA) estimation plays a vital role in many applications. Beamforming is the most prominent technique to estimate DOA. In this survey, a study of various beamforming techniques and algorithms to estimate the direction of arrival of a signal is made.

Piezoelectric Sensors for Lamb Waves’ Direction of Arrival (DoA) Estimation [PDF]

open access: yesEUROSENSORS 2018, 2018
A novel strategy to design piezoelectric sensor clusters suited for direction of arrival (DoA) estimation of Lamb waves is presented in this work. The designed clusters are composed by three piezoelectric patches (P1, P2 e P3) to be bonded on the structure to be inspected.

Does Fit Always Fit? The Paradox of Brand–Cause Misfit and Authenticity

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Brand–cause research generally treats coherence between a brand and a social cause as a prerequisite for authenticity, leaving unexplained why some moderately misfitting initiatives are judged more authentic than expected. We develop a paradox‐based process account in which authenticity arises not only from coherence but also from consumers ...

Spaceborne Distributed Array Processing for Precision Source Localization

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Satellite‐based signals intelligence and spectrum sensing increasingly rely on low‐latency signal localization. However, operational processing chains often remain ground‐based, stressing feeder links and limiting scalability as constellations grow.

Political Partisanship and State‐Level Bank Efficiency

open access: yesFinancial Review, Volume 61, Issue 4, Page 1197-1223, November 2026.
ABSTRACT We examine the relationship between political partisanship and commercial bank efficiency in the United States from 1972 to 2020, assessing the persistent influence of political affiliations at the state and District of Columbia levels. Bank efficiency scores are estimated using a double‐bootstrap approach, and the analysis is conducted within

Measuring and Mapping Urban NO2 Pollution Heterogeneity Using a Custom Pandora Spectrometer Experiment and Observations From TEMPO

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Nitrogen dioxide (NO2) is a primary pollutant present at high concentrations in urban areas. Ground based measurements remain sparse and satellite observations rely on retrievals, so understanding intraurban, diurnal‐scale changes in NO2 is challenging.

Space‐Time Metasurface Antenna Enabled High‐Dimensional Electromagnetic Modulation for Intrinsic Physical Layer Security

open access: yesAdvanced Science, Volume 13, Issue 57, 14 October 2026.
The concept of high‐dimensional EM modulation using the STMA for physical layer secure communication is illustrated in figure. The STMA consists of a series of programmable unit cells, with 1‐bit reconfigurable phase states (0/π). The STMA is excited by a monochromatic continuous wave (CW) at frequency fc and controlled by a field‐programmable gate ...

Toward Predictable Nanomedicine: Current Forecasting Frameworks for Nanoparticle–Biology Interactions

open access: yesAdvanced Intelligent Discovery, Volume 2, Issue 5, October 2026.
Predictive models successfully screen nanoparticles for toxicity and cellular uptake. Yet, complex biological dynamics and sparse, nonstandardized data limit their accuracy. The field urgently needs integrated artificial intelligence/machine learning, systems biology, and open‐access data protocols to bridge the gap between materials science and safe ...

Optical Radiation Pressure: Resonant Mechanical Excitation of Thin Films

open access: yesAnnalen der Physik, Volume 538, Issue 10, October 2026.
The modulation of a laser beam generates a modulated radiation pressure force acting on a thin film. A resonant response is observed, leading to a net average thinning of the film. ABSTRACT Optical radiation pressure was directly observed for the first time more than a century ago.

Improved Power Tracking and Performance Evaluation Using a Tri‐Meta Hybrid DOA–CSA–WOA‐Based MPPT Controller for Standalone PV System

open access: yesEnergy Science &Engineering, Volume 14, Issue 10, Page 4963-4987, October 2026.
A Tri‐Meta Hybrid DOA–CSA–WOA Maximum Power Point Tracking controller is developed to enhance photovoltaic system performance. The proposed approach achieves higher tracking efficiency, faster convergence, and robust operation under dynamic irradiance and partial shading conditions.
