Research progress on the depth of anesthesia monitoring based on the electroencephalogram

Ibrain, Volume 11, Issue 1, Page 32-43, Spring 2025.
Electroencephalogram (EEG) can noninvasive, continuous, and real‐time monitor the state of brain electrical activity, and the monitoring of EEG can reflect changes in the depth of anesthesia (DOA). The development of artificial intelligence can enable anesthesiologists to extract, analyze, and quantify DOA from complex EEG data.

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

Psychology &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 ...

Political Partisanship and State‐Level Bank Efficiency

Financial Review, EarlyView.
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

Parallel Complementary Virtual Arrays Algorithm for Direction of Arrival (DOA) Estimation

International Journal on Recent and Innovation Trends in Computing and Communication, 2023
This Paper discusses the challenges faced by previous method 2D Direction of Arrival (DOA) systems, such as low degrees of freedom, poor resolution, and significant estimation errors in scenarios with small snapshots. In response to these issues, the present method proposes a low-complexity 2D Direction of Arrival (DOA) estimation algorithm based on a ...

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

Advanced 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 ...

Tensor-Based Angle Estimation Approach for Strictly Noncircular Sources with Unknown Mutual Coupling in Bistatic MIMO Radar

Sensors, 2018
In the paper, the estimation of joint direction-of-departure (DOD) and direction-of-arrival (DOA) for strictly noncircular targets in multiple-input multiple-output (MIMO) radar with unknown mutual coupling is considered, and a tensor-based angle ...

TEMPO Applications During Poor Wintertime Air Quality in Salt Lake City: An Analysis of Persistent Cold Air Pooling Events

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract During the wintertime, the Salt Lake Valley (SLV) experiences episodes of poor air quality during persistent cold air pools (PCAPs), wherein the atmospheric boundary layer remains stable for several days. We examine insights into the accumulation of primary emissions during PCAPs gained from NO2 tropospheric column abundances derived from ...
