Advanced Intelligent Systems, EarlyView.Four decades of retinal vessel segmentation research (1982–2025) are synthesized, spanning classical image processing, machine learning, and deep learning paradigms. A meta‐analysis of 428 studies establishes a unified taxonomy and highlights performance trends, generalization capabilities, and clinical relevance.

Approximating the Stieltjes integral via a weighted trapezoidal rule with applications
Mathematical and Computer Modelling, 2013 Abstract In this paper we provide sharp error bounds in approximating the weighted Riemann–Stieltjes integral ∫ a b f ( t ) g ( t ) d α ( t ) by the weighted trapezoidal rule f ( a ) + f ( b ) 2 ∫ a b g ( t ) d α ( t ) .

A Soft Robotic Jellyfish with Decoupled Actuators for Agile 3D Locomotion
Advanced Intelligent Systems, EarlyView.This study presents a soft robotic jellyfish featuring a functionally decoupled actuation architecture. By separating propulsion, steering, and vertical regulation into independent modules, the robot overcomes conventional coupled‐motion limitations. Utilizing a passive‐valve‐based differential drag strategy and lateral water jets, it achieves agile 3D

American Journal of Botany, EarlyView.Abstract Premise Since its emergence in the Mesozoic, Sequoia (Cupressaceae) has been considered to possess conserved leaf morphology. However, recent studies have shown that the leaves of extant S. sempervirens become smaller, with a scale form, with increasing tree height.

A Simple Approximation of Productivity Scores of Fuzzy Production Plans [PDF]
This paper suggests a simple approximation procedure for the assessment of productivity scores with respect to fuzzy production plans. The procedure has a clear economic interpretation and all the necessary calculations can be performed in a spreadsheet ...

Modeling of Natural Settling in a Trapezoidal Sedimentation Basin
, 1994 The objectives of this thesis are to 1) review current theory relative to numerically modeling a trapezoidal settling basin, 2) develop a more appropriate model to better predict settling and deposition within a basin, and 3) confirm the accuracy of the ...

The Anatomical Record, EarlyView.Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Approximating the Stieltjes integral by using the generalized trapezoid rule
Le Matematiche, 2011 Summary: The generalized trapezoid rule is established on the notion of the derivative of a function with respect to an increasing function. This is then used to approximate the Stieltjes integral.

The Anatomical Record, EarlyView.Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,
