The overestimation of equipartition magnetic field strengths from synchrotron emission using synthetically observed galaxies

Posted by dbos Stanford

Kavli Affiliate: Susan E. Clark | First 5 Authors: Tara Dacunha, Sergio Martin-Alvarez, Susan E. Clark, Enrique Lopez-Rodriguez, | Summary: Understanding the role that magnetic fields play on the stage of galaxy formation requires accurate methods for inferring the properties of extragalactic magnetic fields. Radio synchrotron emission has been the most promising avenue to infer […]

Multiple and subject-specific roles of uncertainty in reward-guided decision-making

Posted by dbos UCSD / Salk

Kavli Affiliate: Angela Yu | Authors: Alexander Paunov, Maëva L’Hôtellier, Zoe He, Dalin Guo, Angela Yu and Florent Meyniel | Summary: Decision-making in noisy, changing, and partially observable environments entails a basic tradeoff between immediate reward and longer-term information gain, known as the exploration-exploitation dilemma. Computationally, an effective way to balance this tradeoff is by […]

Impact of Stain Variation and Color Normalization for Prognostic Predictions in Pathology

Posted by dbos Caltech

Kavli Affiliate: Changhuei Yang | First 5 Authors: Siyu, Lin, Haowen Zhou, Richard J. Cote, Mark Watson | Summary: In recent years, deep neural networks (DNNs) have demonstrated remarkable performance in pathology applications, potentially even outperforming expert pathologists due to their ability to learn subtle features from large datasets. One complication in preparing digital pathology […]

Spinon spin current

Posted by dbos UCSB

Kavli Affiliate: Leon Balents | First 5 Authors: Ren-Bo Wang, Naveen Nishad, Anna Keselman, Leon Balents, Oleg A. Starykh | Summary: We present the theory of the longitudinal spin Seebeck effect between a Heisenberg spin-1/2 chain and a conductor. The effect consists of the generation of a spin current across the spin chain-conductor interface in […]

Constraining atmospheric composition from the outflow: helium observations reveal the fundamental properties of two planets straddling the radius gap

Posted by dbos MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Michael Zhang, Jacob L. Bean, David Wilson, Girish Duvvuri, Christian Schneider | Summary: TOI-836 is a $sim2-3$ Gyr K dwarf with an inner super Earth ($R=1.7,R_oplus$, $P=3.8,d$) and an outer mini Neptune ($R=2.6,R_oplus$, $P=8.6,d$). Recent JWST/NIRSpec 2.8–5.2 $mu$m observations have revealed flat transmission spectra for both planets. […]
