Effects of mirror birefringence and its fluctuations to laser interferometric gravitational wave detectors

Posted by klaurent July 31, 2023Caltech

Kavli Affiliate: Rana Adhikari | Summary:Crystalline materials are promising candidates as substrates or high-reflective coatings of mirrors to reduce thermal noises in future laser interferometric gravitational wave detectors. However, birefringence of such materials could degrade the sensitivity of gravitational wave detectors, not only because it can introduce optical losses, but also because its fluctuations create […]

IXPE and multi-wavelength observations of blazar PG 1553+113 reveal an orphan optical polarization swing

Posted by klaurent July 31, 2023MIT

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Riccardo Middei, Matteo Perri, Simonetta Puccetti, Ioannis Liodakis, Laura Di Gesu | Summary: The lower energy peak of the spectral energy distribution of blazars has commonly been ascribed to synchrotron radiation from relativistic particles in the jets. Despite the consensus regarding jet emission processes, the particle […]

Poly-MOT: A Polyhedral Framework For 3D Multi-Object Tracking

Posted by klaurent July 31, 2023Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Xiaoyu Li, Tao Xie, Dedong Liu, Jinghan Gao, Kun Dai | Summary: 3D Multi-object tracking (MOT) empowers mobile robots to accomplish well-informed motion planning and navigation tasks by providing motion trajectories of surrounding objects. However, existing 3D MOT methods typically employ a single similarity metric and physical […]

Echoes Beyond Points: Unleashing the Power of Raw Radar Data in Multi-modality Fusion

Posted by dbos July 31, 2023Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Yang Liu, Feng Wang, Naiyan Wang, Zhaoxiang Zhang, | Summary: Radar is ubiquitous in autonomous driving systems due to its low cost and good adaptability to bad weather. Nevertheless, the radar detection performance is usually inferior because its point cloud is sparse and not accurate due to […]

Chronic brain functional ultrasound imaging in freely moving rodents performing cognitive tasks

Posted by klaurent July 29, 2023August 8, 2023Hopkins

Kavli Affiliate: Adam S. Charles | Authors: Ahmed El Hady, Daniel Y Takahashi, Ruolan Sun, Oluwateniola Akinwale, Tyler Boyd-Meredith, Yisi Zhang, Adam Charles and Carlos Brody | Summary: Functional ultrasound imaging (fUS) is an emerging imaging technique that indirectly measures neural activity via changes in blood volume. To date it has not been used to […]

Hallucination proneness alters sensory feedback processing in self-voice production

Posted by klaurent July 29, 2023August 8, 2023Hopkins

Kavli Affiliate: David Linden | Authors: Suvarnalata Xanthate Duggirala, Michael Schwartze, Lisa K Goller, David E.J. Linden, Ana Pinheiro and Sonja A Kotz | Summary: Background: Sensory suppression occurs when hearing ones self-generated voice, as opposed to passively listening to ones own voice. Quality changes of sensory feedback to the self-generated voice can increase attentional […]

Existence and regularity of pullback attractors for nonclassical non-autonomous diffusion equations with delay

Posted by klaurent July 28, 2023Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Bin Yang, Yuming Qin, Alain Miranville, Ke Wang, | Summary: In this paper, we consider the asymptotic behavior of weak solutions for non-autonomous diffusion equations with delay in time-dependent spaces when the nonlinear function $f$ is critical growth, the delay term $g(t, u_t)$ contains some hereditary characteristics […]
