Growth media affects susceptibility of air-lifted human nasal epithelial cell cultures to SARS-CoV2, but not Influenza A, virus infection

Posted by klaurent Hopkins

Kavli Affiliate: Michael Beer | Authors: Jessica D. Resnick, Jo L. Wilson, Eddy Anaya, Abigail Conte, Maggie Li, William Zhong, Michael A. Beer and Andrew Pekosz | Summary: Primary differentiated human epithelial cell cultures have been widely used by researchers to study viral fitness and virus-host interactions, especially during the COVID19 pandemic. These cultures recapitulate […]

Annealing-tunable charge density wave in the kagome antiferromagnet FeGe

Posted by dbos UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Xueliang Wu, Xinrun Mi, Long Zhang, Chin-Wei Wang, Nour Maraytta | Summary: The unprecedented phenomenon that a charge density wave (CDW) emerges inside the antiferromagnetic (AFM) phase indicates an unusual CDW mechanism associated with magnetism in FeGe. Here, we demonstrate that both the CDW and magnetism of […]

IXPE and XMM-Newton observations of the Soft Gamma Repeater SGR 1806-20

Posted by klaurent MIT

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Roberto Turolla, Roberto Taverna, Gian Luca Israel, Fabio Muleri, Silvia Zane | Summary: Recent observations with the Imaging X-ray Polarimetry Explorer (IXPE) of two anomalous X-ray pulsars provided evidence that X-ray emission from magnetar sources is strongly polarized. Here we report on the joint IXPE and […]

NuSTAR Observations of Abell 665 and 2146: Constraints on Non-Thermal Emission

Posted by klaurent Stanford

Kavli Affiliate: Grzegorz Madejski | Summary:Observations from past missions such as RXTE and Beppo-SAX suggested the presence of inverse Compton (IC) scattering at hard X-ray energies within the intracluster medium of some massive galaxy clusters. In subsequent years, observations by, e.g., Suzaku, and now NuSTAR, have not been able to confirm these detections. We report […]

Effect of Instrumental Polarization with a Half-Wave Plate on the $B$-Mode Signal: Prediction and Correction

Posted by klaurent Tokyo

Kavli Affiliate: Tomotake Matsumura | Summary:We evaluate the effect of half-wave plate (HWP) imperfections inducing intensity leakage to the measurement of Cosmic Microwave Background (CMB) $B$-mode polarization signal with future satellite missions focusing on the tensor-to-scalar ratio $r$. The HWP is modeled with the Mueller formalism, and coefficients are decomposed for any incident angle into […]

Kavli Affiliate: Brian Caffo, Joshua Vogelstein | Authors: Eric W. Bridgeford, Michael Powell, Gregory Kiar, Stephanie Noble, Jaewon Chung, Sambit Panda, Ross Lawrence, Ting Xu, Michael Milham, Brian Caffo and Joshua T. Vogelstein | Summary: Batch effects, undesirable sources of variance across multiple experiments, present significant challenges for scientific and clinical discoveries. Specifically, batch effects […]

Photometry, Centroid and Point-Spread Function Measurements in the LSST Camera Focal Plane Using Artificial Stars

Posted by klaurent Stanford

Kavli Affiliate: Aaron Roodman | Summary:The Vera C. Rubin Observatory’s LSST Camera (LSSTCam) pixel response has been characterized using laboratory measurements with a grid of artificial stars. We quantify the contributions to photometry, centroid, point-spread function size, and shape measurement errors due to small anomalies in the LSSTCam CCDs. The main sources of those anomalies […]
