Retinal Vessel Segmentation: A Comprehensive Review From Classical Methods to Deep Learning Advances (1982–2025)

open access: yesAdvanced 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.

MODELING CHANGES IN THE U.S. DEMAND FOR CROP INSURANCE DURING THE 1990S

open access: yes
The crop insurance purchase decision for a group of Kansas farmers is analyzed using data from 1990sa period that experienced many changes in the federal crop insurance program. Farm-level data are used.

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

open access: yesAdvanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Does risk matter for farm businesses? The effect of crop insurance on production and diversification.

open access: yes
We use a large increase in Federal crop insurance subsidies as a natural experiment to identify the impact of risk on acreage and diversification decisions. Subsidy increases induced greater crop insurance coverage, which reduced farmers' financial risks.

Did Expanding Medicaid Affect Welfare Participation? [PDF]

open access: yes
Using data from the 1988-1996 Current Population Surveys (CPS), we re-examine the evidence presented in Yelowitz (1995) showing that expansions in Medicaid eligibility for children were associated with increased labor force participation and reduced ...

Dielectric Elastomer Actuators as Safe and Effective Tools for Mechanostimulation of Human Cells

open access: yesAdvanced Intelligent Systems, EarlyView.
Replicating physiological forces is crucial for realistic cell models. Dielectric elastomer actuators (DEAs) offer a soft alternative, though their high voltages raised toxicity concerns. We demonstrate that DEA stimulation causes no cell damage, cell death or cell‐cycle disruption, while activating mechanosensitive responses.

Acreage Abandonment, Moral Hazard and Crop Insurance

open access: yes
Empirical evidence for the existence of moral hazard in the U.S. crop insurance program has been inconclusive. Here we use a nested-dynamic programming framework to estimate an intra-seasonal dynamic model that explicitly incorporates a farmer's crop ...

Employee Costs and the Decline in Health Insurance Coverage [PDF]

open access: yes
This paper examines why health insurance coverage fell despite the lengthy economic boom of the 1990s. I show that insurance coverage declined primarily because fewer workers took up coverage when offered it, not because fewer workers were offered ...

An economic evaluation of a crop insurance programme for small-scale commercial farmers in South Africa

open access: yes
Hail insurance is provided by the private sector in South Africa but crop insurance (drought insurance) programmes, after a promising start, failed to attract customers. A crop insurance programme (drought) for small-scale commercial farmers, who are not
