StreamFlow: Streamlined Multi-Frame Optical Flow Estimation for Video Sequences

Kavli Affiliate: Wei Gao | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Occlusions between consecutive frames have long posed a significant challenge in optical flow estimation. The inherent ambiguity introduced by occlusions directly violates the brightness constancy constraint and considerably hinders pixel-to-pixel matching. To address this issue, multi-frame optical flow methods leverage […]

A Geometric Tension Dynamics Model of Epithelial Convergent Extension

Kavli Affiliate: Boris I. Shraiman | First 5 Authors: Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman, , | Summary: Epithelial tissue elongation by convergent extension is a key motif of animal morphogenesis. On a coarse scale, cell motion resembles laminar fluid flow; yet in contrast to a fluid, epithelial cells adhere to each other […]

Low- and High-velocity ion{O}{6} in Milky Way-like Galaxies: the Role of Stellar Feedback

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zhijie Zhang, Xiaoxia Zhang, Hui Li, Taotao Fang, Qingzheng Yu | Summary: Milky Way-type galaxies are surrounded by a warm-hot gaseous halo containing a considerable amount of baryons and metals. The kinematics and spatial distribution of highly-ionized ion species such as ion{O}{6} can be significantly affected by […]

X-ray Polarization of the Eastern Lobe of SS 433

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Philip Kaaret, Riccardo Ferrazzoli, Stefano Silvestri, Michela Negro, Alberto Manfreda | Summary: How astrophysical systems translate the kinetic energy of bulk motion into the acceleration of particles to very high energies is a pressing question. SS 433 is a microquasar that emits TeV gamma-rays indicating the […]

TIC 184743498: The First Tri-Axial Stellar Pulsator

Kavli Affiliate: Saul Rappaport | First 5 Authors: Valencia Zhang, Saul Rappaport, Rahul Jayaraman, Donald W. Kurtz, Gerald Handler | Summary: We have discovered a $delta$ Scuti pulsator in a tight binary (P = 1.053 d) with nine pulsation modes whose frequencies are between 38 and 56 d$^{-1}$. Each of these modes exhibits amplitude modulations […]
