Optimal deep learning activity recognition pipeline using animal bio‐logging data
Methods in Ecology and Evolution, EarlyView.Abstract Animal activity recognition using supervised machine learning on bio‐logging data has revolutionized behavioural studies on wildlife and livestock over the past decade. These studies' analytic pipelines differ substantially though, being based on various sensors, features, algorithms and hyperparameter values, which has caused suboptimal or ...

Andrology, EarlyView.ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native

Representation and Weak Convergence of Stochastic Integrals with Fractional Integrator Processes [PDF]
This paper considers the asymptotic distribution of the covariance of a nonstationary fractionally integrated process with the stationary increments of another such process - possibly, itself.

Artificial Organs, EarlyView.Comparative MRI of in vivo kidneys and ex vivo donor kidneys during NMP revealed marked physiological differences and limited correspondence with conventional perfusion or injury metrics. These distinct ex vivo MRI signatures emphasize the need to consider parameters beyond conventional in vivo functional markers when assessing organ viability during ...

Terrain Synthesis and Authoring based on Iso‐Contours
Computer Graphics Forum, EarlyView.Abstract Digital terrains are central to realistic landscape depiction, yet authoring tools must balance perceptual realism with intuitive artistic control. We propose a compact vector‐based representation that models terrain as nested iso‐contours, inspired by geomorphology and cartography.

, 2007 On the surface of a vertically oscillated fluid, capillary waves with a clearly discernible wavelength are formed if the amplitude of the oscillations exceeds a critical value. Particles sprinkled on the fluid surface are experimentally found to move

The FEBS Journal, EarlyView.Congenital dyserythropoietic anemia type I (CDA‐I) arises from mutations in Codanin1 and CDIN1. Using quantitative biophysical approaches, we show that disease‐associated mutations disrupt the CDIN1‐Codanin1 complex. Our findings provide critical insights into the molecular mechanism that links protein dysfunction to disturbing chromatin arrangement ...

Tempered fractional Brownian motion
, 2014 Tempered fractional Brownian motion (TFBM) modifies the power law kernel in the moving average representation of a fractional Brownian motion (FBM), adding an exponential tempering. It also has a harmonizable representation.
