Kavli Affiliate: T. Higuchi | First 5 Authors: K. Adamczyk, K. Adamczyk, , , | Summary: The silicon strip sensors of the Belle II silicon vertex detector were irradiated with 90 MeV electron beams up to an equivalent 1-MeV-neutron fluence of $3.0times 10^13~rm n_rm eq/rm cm^2$. We measure changes in sensor properties induced by radiation […]
Kavli Affiliate: Jia Liu | First 5 Authors: Tian Xie, Tian Xie, , , | Summary: Performative prediction (PP) is an algorithmic framework for optimizing machine learning (ML) models where the model’s deployment affects the distribution of the data it is trained on. Compared to traditional ML with fixed data, designing algorithms in PP converging […]
Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Giacomo Sala, Giacomo Sala, , , | Summary: The surface states of 3D topological insulators possess geometric structures that imprint distinctive signatures on electronic transport. A prime example is the Berry curvature, which controls electric frequency doubling via a higher order moment, called Berry curvature triple. […]
Kavli Affiliate: Xuebing Wu | First 5 Authors: Di Wu, Di Wu, , , | Summary: Wide-separation lensed quasars (WSLQs) are a rare subclass of strongly lensed quasars produced by massive galaxy clusters. They provide valuable probes of dark-matter halos and quasar host galaxies. However, only about ten WSLQ systems are currently known, which limits […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Michael Harris, Michael Harris, , , | Summary: We study properties of the restriction of discrete series representations of $G=U(p,q)$ to $G’= U(p-1,q)$ and the corresponding symmetry breaking operators in $operatornameHom_G'(pi|_G’, pi’)$. This leads to the introduction of elementary and coherent pairs of discrete series representations and […]
Kavli Affiliate: Gang Su | First 5 Authors: Chun-Yi Xue, Chun-Yi Xue, , , | Summary: We demonstrate that spin PN junctions-magnetic semiconductor homojunctions with spin splitting-induced band offsets-fundamentally redefine carrier transport via spin-dependent recom bination probabilities. By integrating this mechanism into the Shockley model, we predict a near 100 enhancement in magnetoresistance sensitivity under […]
Kavli Affiliate: David A. Muller | First 5 Authors: Saif Siddique, Saif Siddique, , , | Summary: Classical nucleation theory predicts size-dependent nucleation and melting due to surface and confinement effects at the nanoscale. In correlated electronic states, observation of size-dependent nucleation and melting is rarely reported, likely due to the extremely small length scales […]
Kavli Affiliate: Stephanie Wehner | First 5 Authors: Bethany Davies, Bethany Davies, , , | Summary: In the performance analysis of quantum networks, it is common to approximate bipartite entangled states as either being Bell-diagonal or Werner states. We refer to these as twirled approximations because it is possible to bring any state to such […]
Kavli Affiliate: Sara Seager | First 5 Authors: Amélie Gressier, Amélie Gressier, , , | Summary: We present the James Webb Space Telescope (JWST) transmission spectrum of the exoplanet HAT-P-26 b (18.6 Earth masses, 6.33 Earth radii), based on a single transit observed with the JWST NIRSpec G395H grating. We detect water vapor (ln B […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Ke Wang, , , | Summary: Automatic Pronunciation Assessment (APA) is critical for Computer-Assisted Language Learning (CALL), requiring evaluation across multiple granularities and aspects. Large Multimodal Models (LMMs) present new opportunities for APA, but their effectiveness in fine-grained assessment remains uncertain. This work investigates fine-tuning […]
