Overlapped Arithmetic Codes

open access: yes
Arithmetic codes are usually deemed as the most important means to implement lossless source coding, whose principle is mapping every source symbol to a sub-interval in [0, 1). For every source symbol, the length of its mapping sub-interval is exactly equal to its probability.

Prenatal exposure to antihypertensive medication: A systematic review of neurodevelopmental and educational outcomes

open access: yesJCPP Advances, EarlyView.
This systematic review investigated the association of prenatal exposure to antihypertensive medication with longer‐term poor neurodevelopmental outcomes by evaluating the findings from existing literature. We undertook a systematic review of previous studies looking specifically at neurodevelopmental outcomes in children.

Essential and toxic elements intake from botanical extracts: a probabilistic risk–benefit evaluation within the Italian dietary context

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Botanical extracts are widely consumed for their claimed health benefits, yet their safety profile with respect to chronic consumption remains poorly characterized. Understanding the potential health risks associated with their inorganic content is a crucial issue for ensuring safe use, along with a characterization of the ...

What is “accuracy”? Rethinking machine learning classifier performance metrics for highly imbalanced, high variance, zero‐inflated species count data

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Machine learning has opened the door for the automated sorting (classification) of images, holograms and acoustic backscatters of individual plankton, invertebrates, fish and marine mammals. However, this field is complicated by decades of paradoxically promising reports of classifier performance that do not correlate with real‐world uptake of

Photonic Systolic Array for All‐Optical Matrix–Matrix Multiplication

open access: yesLaser &Photonics Reviews, EarlyView.
A photonic systolic array is introduced, offering extreme parallelism in matrix‐matrix multiplication based on the synchronized movement of optical pulses along a crossbar array. Optical pulses traveling in perpendicular directions meet at freeform‐designed multiply‐accumulate units, each tailored to generate two signals whose intensity difference ...

Impact of E‐Beam Sterilization on Bioglass Composite Shape Memory Scaffolds

open access: yesMacromolecular Materials and Engineering, EarlyView.
Electron beam (E‐beam) sterilization is an attractive alternative to conventional methods (e.g., ethylene oxide) to sterilize medical devices such as scaffolds used to heal bone defects. Herein, the impact of E‐beam sterilization on the properties of “self‐fitting” shape memory polymer (SMP) scaffolds prepared from resorbable polyesters and a bioglass ...

Micromorpho‐anatomical studies on the leaves and woods of Turkish Daphne (Thymelaeaceae) taxa

open access: yesNordic Journal of Botany, EarlyView.
The identification of Daphne taxa is difficult because of the lack of available morphological characteristics. Here, we aimed to describe leaf and wood micromorpho‐anatomical characteristics of native Turkish Daphne taxa (D. glomerata, D. gnidioides, D. mezereum, D. mucronata, D. oleoides subsp. kurdica, D. pontica and D.

Exploring the Tribological Properties of 3D Printed Polymer Composites: An Experimental Study

open access: yesPolymer Composites, EarlyView.
Tribological pin‐on‐disc testing of FDM‐manufactured pins. Pins made from PLA, TPU, bronze‐filled PLA (BRO), and their combinations were tested against a SAE 1020 steel disc to evaluate friction, wear, and surface morphology. ABSTRACT In recent years, additive manufacturing, especially 3D printing, has been gaining more space in the production of parts
