Synthetic Electrocardiogram Spectrogram Generation Using Generative Adversarial Network‐Based Models: A Comparative Study

Advanced Intelligent Systems, EarlyView.
Cardiovascular diseases are leading death causes; electrocardiogram (ECG) analysis is slow, motivating machine learning and deep learning. This study compares deep convolutional generative adversarial network, conditional GAN, and Wasserstein GAN with gradient penalty (WGAN‐GP) for synthetic ECG spectrograms; Fréchet Inception Distance (FID) and ...

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

Unpacking the Role of Digital Dynamic Capabilities in ESG Performance: A Social Exchange Perspective on Organizational Trust and Identification

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines the role of digital dynamic capabilities (DDCs) in enhancing ESG performance, integrating insights from social exchange theory (SET). By conceptualizing organizational trust and organizational identification as key antecedents of DDCs, we propose that firms fostering trust‐based and identification‐driven environments are ...

Temperature-constrained lidar retrieval of planetary boundary layer height over Chiang Mai, Thailand [PDF]

Atmospheric Measurement Techniques
Accurate determination of the planetary boundary layer (PBL) height, mixing-layer height (MLH), and aerosol layer top (ALT) is essential for air quality and climate studies, particularly in regions with complex aerosol dynamics such as Chiang Mai ...

Digital Platform Capabilities and Circular Economy: Impact of Customer Green Pressure on Frugal Innovative Strategies

Business Strategy and the Environment, EarlyView.
ABSTRACT Manufacturing entities in emerging economies face significant obstacles implementing circular economy principles due to resource‐constrained environments. Arguably, manufacturers need customer green pressure to propel the circular economy, alongside frugal innovative strategies.

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

Speaker Recognition Using Wavelet Cepstral Coefficient, I-Vector, and Cosine Distance Scoring and Its Application for Forensics

Journal of Electrical and Computer Engineering, 2016
An important application of speaker recognition is forensics. However, the accuracy of speaker recognition in forensic cases often drops off rapidly because of the ill effect of ambient noise, variable channel, different duration of speech data, and so ...

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions

Canadian Journal of Statistics, EarlyView.
Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

An Improved Iterative Fitting Method to Estimate Nocturnal Residual Layer Height

Atmosphere, 2016
The planetary boundary layer (PBL) is an atmospheric region near the Earth’s surface. It is significant for weather forecasting and for the study of air quality and climate. In this study, the top of nocturnal residual layers—which are what remain of the
