Alternating Spatial‐Temporal Optimization for Continuous Collision Detection of Signed Distance Fields

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present a fast, robust method for continuous collision detection (CCD) directly between pairs of complex signed distance fields (SDFs). By casting CCD as an alternating spatio‐temporal optimization and driving a small set of smartly sampled surface points along SDF tangent spaces, our approach avoids dense sampling or triangle meshes ...

Antimicrobial photodynamic therapy in Candida spp. biofilms: In vitro and in vivo protocols

open access: yesPhotochemistry and Photobiology, EarlyView.
This review addresses the critical challenges in translating in vitro antimicrobial photodynamic therapy protocols to in vivo models, with a particular focus on the hurdles of standardization. The vast diversity in photosensitizers and light parameters across different target cells and models requires a rigorous optimization process.

Coating stent materials with polyhedral oligomeric silsesquioxane-poly(carbonateurea)urethane nanocomposites [PDF]

open access: yes, 2009
The long-term efficacy of coronary or peripheral stenting is limited by in-stent restenosis (ISR), which occurs in 15 to 30% of patients and is attributed primarily to neointimal hyperplasia.

Using polyhedral models to automatically sketch idealized geometry for structural analysis [PDF]

open access: yes, 2001
Simplification of polyhedral models, which may incorporate large numbers of faces and nodes, is often required to reduce their amount of data, to allow their efficient manipulation, and to speed up computation.

Surface Ligand Engineering in Quantum Dot Photocatalysis: Mechanisms, Design Principles, and Applications

open access: yesAdvanced Chemical Engineering, Volume 1, Issue 2, December 2026.
Surface ligands govern quantum dot photocatalysis through thermodynamic band‐edge tuning, kinetic charge‐transfer regulation, and microenvironmental control. Rational ligand engineering, using short‐chain, inorganic, conjugated, or dual‐ligand systems, enables efficient solar fuel production, selective organic transformations, environmental remediation,

On the noninterpolation of polyhedral maps [PDF]

open access: yes, 1994
In this paper we show that if attention is restricted to polyhedral embeddings of graphs, no theorem analogous to the Duke interpolation theorem for 2-cell embeddings is true.

Evaluation of Phantom Doping Materials in Quantitative Susceptibility Mapping

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 4, Page 1545-1556, October 2026.
ABSTRACT Purpose To measure magnetic susceptibility (χ) with Quantitative Susceptibility Mapping (QSM) and evaluate its repeatability using four phantom doping materials relevant to QSM applications. Methods A cylindrical phantom was constructed containing vials of agarose gel doped with two paramagnetic materials (ferritin, USPIO) and two diamagnetic ...

Euclidean decompositions of hyperbolic manifolds and their duals [PDF]

open access: yes, 2007
Epstein and Penner constructed in [EP88] the Euclidean decomposition of a non-compact hyperbolic n-manifold of finite volume for a choice of cusps, n >= 2. The manifold is cut along geodesic hyperplanes into hyperbolic ideal convex polyhedra.
