Optimizing 3D Bin Packing of Heterogeneous Objects Using Continuous Transformations in SE(3)
Advanced Intelligent Systems, EarlyView.This article presents a method for solving the three‐dimensional bin packing problem for heterogeneous objects using continuous rigid‐body transformations in SE(3). A heuristic optimization framework combines signed‐distance functions, neural network approximations, point‐cloud bin modeling, and physics simulation to ensure feasibility and stability ...

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.

Lost in aggregation? On the importance of local food price data for food poverty estimates
American Journal of Agricultural Economics, EarlyView.Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Climate change and perennial crop production: Evidence of yield impact and adaptation in California
American Journal of Agricultural Economics, EarlyView.Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...

Associations between inclusive community coalition leadership and use of evidence‐based practices
American Journal of Community Psychology, EarlyView.Abstract Community coalitions have the potential to elicit diverse participants' perspectives on complex issues and generate shared commitment to adaptive strategies. Ideally, these approaches have been found effective elsewhere. Despite evidence that leadership plays a generally important role in coalitions, there have been limited prior findings ...

Automated drusen segmentation and quantification in SD-OCT images [PDF]
Medical Image Analysis, 2013 Spectral domain optical coherence tomography (SD-OCT) is a useful tool for the visualization of drusen, a retinal abnormality seen in patients with age-related macular degeneration (AMD); however, objective assessment of drusen is thwarted by the lack of a method to robustly quantify these lesions on serial OCT images.

Intraoperative SD-OCT in Macular Surgery
Ophthalmic Surgery, Lasers and Imaging Retina, 2012BACKGROUND AND OBJECTIVE: Intraoperative use of spectral-domain optical coherence tomography (SD-OCT) using an OCT-mounted surgical microscope could provide additional information to predict visual outcomes of macular surgery and identify intraoperative changes in the macular anatomy that affect visual recovery.

Characteristic SD-OCT Findings in Preeclampsia
Ophthalmic Surgery, Lasers and Imaging Retina, 2012High-resolution spectral-domain optical coherence tomography of a patient affected by acute macular edema secondary to preeclampsia is described. The particular optical coherence tomography pattern was characterized by bilateral macular edema with a tent-shaped organization, associated with massive neurosensorial retinal detachment.

Drusen segmentation with sparse volumetric SD-OCT sampling
Medical Imaging 2021: Image Processing, 2021Age-Related Macular Degeneration (AMD) is a common eye disease characterized by the build-up of drusen, small deposits of extracellular materials in the macula. Early detection of drusen is key to understanding the progression of AMD. Therefore, accurate and robust segmentation of drusen during AMD progression is important for automated detection ...
