Posterior Horn Meniscus Centroid Position Is Altered Soon After Noncontact ACL Injury in Males and Females

open access: yesJournal of Orthopaedic Research, Volume 44, Issue 5, May 2026.
ABSTRACT Anterior cruciate ligament (ACL) injury and subsequent changes in the magnitude and distribution of contact stress about the articular surfaces of the knee are associated with post‐traumatic osteoarthritis. Soon after ACL injury, changes in tibial articular cartilage thickness occur that can be explained, in part, by abnormal positioning of ...

Freeze-out from HBT and Coulomb Effects

open access: yes, 1998
The freeze-out of hot and dense hadronic matter formed in relativistic nuclear collisions is probed by HBT interferometry of identical pions, kaons, etc. Coulomb repulsion/attraction of positive/negative particles show up at small particle momenta and is

A Multi‐Dimensional Cathodoluminescence Detector With 3D Printed Micro‐Optics on a Fiber

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 4, April 2026.
A fiber‐based cathodoluminescence (CL) spectroscopy detector is realized by printing a micro‐optical lens directly onto the fiber's facet using two‐photon polymerization. This compact collection scheme enables efficient CL acquisition across complex sample geometries, offering simplified alignment, modular integration, and access to spatially resolved ...

Viscous Corrections to Spectra, Elliptic Flow, and HBT Radii

open access: yes, 2002
I compute the first viscous correction to the thermal distribution function. With this correction, I calculate the effect of viscosity on spectra, elliptic flow, and HBT radii.

Large-signal charge control modeling of photoreceivers for applications up to 40 Gb/s [PDF]

open access: yes, 2009
A charge control model was used to simulate the sensitivity and responsivity in a range of photodetector configurations including heterojunction bipolar phototransistors (HPTs), PIN-HBT, and APDs.

Multiple Photon Subtraction on Light with Tunable Intensity Correlations

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 4, April 2026.
Subtracting photons from bunched classical light paradoxically increases its intensity. This systematic study combines theory and experiment to map photon subtraction effects across Gaussian optical fields with tunable g(2)${\rm g}^{(2)}$(0) from 1.00 to 2.85. Beam‐splitter‐based heralded detection confirms the transformation ξ→ξ$\xi \rightarrow \xi$ +

HBT with Space- vs. Time-like Hydrodynamic Freezeout [PDF]

open access: yes, 1997
Bose-Einstein correlations in relativistic heavy ion collisions and their dependence on the freeze-out condition in hydrodynamic models is compared to time-like freeze-out, where particles are emitted away only from the surface, i.e. space- vs. time-like

Transverse momentum dependence of Hanbury Brown-Twiss radii of pions from a perfectly opaque source with hydrodynamic flow

open access: yes, 2003
We investigate the transverse momentum dependence of pion HBT radii on the basis of a hydrodynamical model. Recent experimental data show that $R_{\text{out}}/R_{\text{side}} < 1$, which suggests a strong opaqueness of the source.

Pion interferometry in Au+Au collisions at $\sqrt{\mathrm{s}_{_{\mathrm{NN}}}}$ = 200 GeV [PDF]

open access: yes, 2005
We present a systematic analysis of two-pion interferometry in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV using the STAR detector at RHIC. We extract the HBT radii and study their multiplicity, transverse momentum, and azimuthal angle dependence.

DNA‐Based Exciton Collider to Monitor Exciton Diffusion and Annihilation

open access: yesSmall Structures, Volume 7, Issue 4, April 2026.
We used DNA origami to build one‐dimensional photonic wires with up to nine precisely positioned organic dyes. Excitons are injected from both ends via FRET and diffuse along the wire; their encounters trigger singlet‐singlet annihilation, leading to single‐photon emission.
