Comparing Different Light Models for Virtual Electrodes in Optoelectronic Tweezers
ELECTROPHORESIS, EarlyView.ABSTRACT Optoelectronic tweezers (OET) allow for the physical manipulation of particles of interest via dielectrophoresis (DEP) in microfluidic devices. To produce the nonuniform electric field required to enable DEP, light is used to expose a photoconductive film and create a so‐called virtual electrode (VE).

SDF‐Guided Point Cloud Generation Framework for Mesh‐Free CFD
International Journal for Numerical Methods in Fluids, EarlyView.This paper presents different methods for generating clouds of points around objects for use with meshless methods in computational fluid dynamics. This image shows the cloud generated around the original ROBIN body. ABSTRACT Meshing is a bottleneck of CFD workflows, especially when complex geometries are considered.

Combining Volatility Forecasts of Duration‐Dependent Markov‐Switching Models
Journal of Forecasting, EarlyView.ABSTRACT Duration‐dependent Markov‐switching (DDMS) models require a user‐specified duration hyperparameter, for which there is currently no established procedure for estimation or testing. As a result, an ad‐hoc duration choice must be heuristically justified.

Emerging Technologies for Timely Point‐of‐Care Diagnostics of Skin Cancer
Global Challenges, EarlyView.With the global incidence of skin cancer on the rise and a persistent lack of rapid, noninvasive and sensitive point‐of‐care diagnostic platforms, current and emerging technologies are critically reviewed. Among these, the emerging Raman spectroscopy system is identified as a promising complementary to conventional costly and invasive methods, offering

Independent Sets of Random Trees and Sparse Random Graphs
Journal of Graph Theory, EarlyView.ABSTRACT An independent set of size k $k$ in a finite undirected graph G $G$ is a set of k $k$ vertices of the graph, no two of which are connected by an edge. Let xk ( G ) ${x}_{k}(G)$ be the number of independent sets of size k $k$ in the graph G $G$ and let α ( G ) = max { k ≥ 0 : x k ( G ) ≠ 0 } $\alpha (G)=\max \{k\ge 0:{x}_{k}(G)\ne 0\}$. In 1987,

Depth‐enhanced light field camera system based on focus‐tunable geometric phase lens module
Journal of the Society for Information Display, EarlyView.We propose a GPL‐based LF camera that significantly extends the depth range over passive optics. During elemental image acquisition and LF rendering, chromatic aberration is compensated by adjusting reconstruction depth and magnification per color channel, with optimized GPL operations considering color‐dependent depth of focus.
