Kavli Affiliate: Tom Melia | First 5 Authors: David E. Kaplan, Tom Melia, Surjeet Rajendran, , | Summary: Three possible strategies have been advocated to solve the strong CP problem. The first is the axion, a dynamical mechanism that relaxes any initial value of the CP violating angle $bar{theta}$ to zero. The second is the […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Alessandro Peca, Michael J. Koss, Roberto Serafinelli, Claudio Ricci, C. Megan Urry | Summary: We report the serendipitous discovery of an absorption feature at 4.8 keV in the NuSTAR spectra of ESP 39607, a Seyfert 2 galaxy at $z = 0.201$, observed in May 2023 and August […]
Kavli Affiliate: Charles M. Rice | Authors: Matthew A Cattle, Lauren C Aguado, Samantha Sze, Dylan Yueyang Wang, Thales Papagiannakopoulos, Susan Smith, Charles M Rice, William Matthew Schneider and John T Poirier | Summary: Retrons are a retroelement class found in diverse prokaryotes that can be adapted to augment CRISPR-Cas9 genome engineering technology to efficiently […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Andrew Goh, Hitoshi Murayama, Gup Singh, Bethany Suter, Jason Wong | Summary: We present exact non-perturbative solutions to chiral gauge theories based on the $E_6$ gauge group and several matter fermions in the fundamental $bf{27}$-dimensional representation. They are obtained when supersymmetric versions are perturbed by small supersymmetry […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Saghar S. Hosseini, Yuji Tachikawa, Hao Y. Zhang, , | Summary: We revisit the issue of how the perturbative and global fermion anomaly of Type I string theory in ten dimensions is cancelled by the Green-Schwarz mechanism using the RR fields. This will be done by realising […]
Kavli Affiliate: Lina Necib | First 5 Authors: Dylan Folsom, Carlos Blanco, Mariangela Lisanti, Lina Necib, Mark Vogelsberger | Summary: The sensitivity of direct detection experiments depends on the phase-space distribution of dark matter near the Sun, which can be modeled theoretically using cosmological hydrodynamical simulations of Milky Way-like galaxies. However, capturing the halo-to-halo variation […]
Kavli Affiliate: David A. Muller | First 5 Authors: Chia-Hao Lee, Steven E. Zeltmann, Dasol Yoon, Desheng Ma, David A. Muller | Summary: Electron ptychography has recently achieved unprecedented resolution, offering valuable insights across diverse material systems, including in three dimensions. However, high-quality ptychographic reconstruction is computationally expensive and time consuming, requiring a significant amount […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Feng Yuan, Yifan Gao, Wenbin Wu, Keqing Wu, Xiaotong Guo | Summary: Accurate multi-modal medical image translation requires ha-rmonizing global anatomical semantics and local structural fidelity, a challenge complicated by intermodality information loss and structural distortion. We propose ABS-Mamba, a novel architecture integrating the Segment Anything Model […]
Kavli Affiliate: Jos W. Zwanikken | First 5 Authors: Tamara Mijatović, Aimée R. Kok, Jos W. Zwanikken, Marianne Bauer, | Summary: Transcription factor concentrations provide signals to cells that allow them to regulate gene expression to make correct cell fate decisions. Calculations for noise bounds in gene regulation suggest that clustering or cooperative binding of […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Marcelo C. Vergara, Abbas Askar, Albrecht W. H. Kamlah, Rainer Spurzem, Francesco Flammini Dotti | Summary: Context. We present simulations of a massive young star cluster using textsc{Nbody6++GPU} and textsc{MOCCA}. The cluster is initially more compact than previously published models, with one million stars, a total mass […]
