Method for all-sky searches of continuous gravitational wave signals using the frequency-Hough transform

open access: yes, 2014
In this paper we present a hierarchical data analysis pipeline for all-sky searches of continuous gravitational wave signals, like those emitted by spinning neutron stars asymmetric with respect to the rotation axis, with unknown position, rotational ...

Hyperentanglement in Nanophotonic Systems With Discrete Rotational Symmetry

open access: yesNanophotonics, Volume 15, Issue 6, 27 March 2026.
This work introduces a nanophotonic scheme leveraging discrete rotational symmetry to unlock two quantum capabilities: generation of hyperentangled photon pairs in spin and spatial degrees of freedom; and isomorphic mapping that preserves free‐space degrees of freedom, overcoming the information loss in non‐paraxial photonic systems.

PiP‐Plex: A Particle‐in‐Particle System for Multiplexed Quantification of Proteins Secreted by Single Cells

open access: yesAdvanced Materials, Volume 38, Issue 13, 3 March 2026.
Detecting proteins secreted by a single cell while retaining its viability remains challenging. A particles‐in‐particle (PiPs) system made by co‐encapsulating barcoded microparticles (BMPs) with a single cell inside an alginate hydrogel particle is introduced.

An efficient algorithm for line extraction from laser scans [PDF]

open access: yes, 2004
In this paper, an algorithm for extracting line segments from information gathered by a laser rangefinder is presented. The range scan is processed to compute a parameter that is invariant to the position and orientation of straight lines present.

The cascaded Hough transform

open access: yesProceedings of International Conference on Image Processing, 2002
When using the original slope-intercept parameterisation for the Hough transform, the resulting parameter space actually corresponds to the dual space. Indeed, lines are transformed into points, and for every point there is also a corresponding line.

Changes in Shell and Crystal Structure From Life to Sediments: An EBSD Characterization of Subantarctic Planktic Foraminifera

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Fossil foraminifera store a wealth of information about past climates and ecosystems in their shell chemistry. However, these element and isotope signals may be affected by post‐mortem diagenesis (i.e., alteration). Here, we use Electron Backscatter Diffraction (EBSD; crystal orientation mapping) to evaluate the structural integrity of sub ...

Improving the Hough Transform gathering process for affine transformations

open access: yes, 2001
In this paper, we show that significant wrong evidence can be generated when the Hough Transform (HT) is used to extract arbitrary shapes under rigid transformations.
