Kavli Affiliate: Ke Wang | First 5 Authors: Amirhossein Ansari, Amirhossein Ansari, , , | Summary: Recent advancements in Vision-Language Models like CLIP have enabled zero-shot OOD detection by leveraging both image and textual label information. Among these, negative label-based methods such as NegLabel and CSP have shown promising results by utilizing a lexicon of […]
Kavli Affiliate: Eliska Greplova | First 5 Authors: Christian Kraglund Andersen, Christian Kraglund Andersen, , , | Summary: It is widely accepted that quantum error correction is essential for realizing large-scale fault-tolerant quantum computing. Recent experiments have demonstrated error correction codes operating below threshold, primarily using local planar codes such as the surface code and […]
Kavli Affiliate: Eric Oberla | First 5 Authors: Jaime Álvarez-Muñiz, Jaime Álvarez-Muñiz, , , | Summary: The Giant Radio Array for Neutrino Detection (GRAND) is an envisioned observatory of ultra-high-energy particles of cosmic origin, with energies in excess of 100 PeV. GRAND uses large surface arrays of antennas to look for the radio emission from […]
Kavli Affiliate: Sara Seager | First 5 Authors: , , , , | Summary: The orbital eccentricities of brown dwarfs encode valuable information of their formation and evolution history, providing insights into whether they resemble giant planets or stellar binaries. Here, we report the discovery of TOI-5575b, a long-period, massive brown dwarf orbiting a low-mass […]
Kavli Affiliate: Bo Gu | First 5 Authors: Songhan Zhao, Songhan Zhao, , , | Summary: In this paper, we consider a semantic-aware reconfigurable intelligent surface (RIS)-assisted wireless network, where multiple semantic users (SUs) simultaneously transmit semantic information to an access point (AP) by using the non-orthogonal multiple access (NOMA) method. The SUs can reshape […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Alexander C. Ogren, Alexander C. Ogren, , , | Summary: Wave propagation on the surface of a material contains information about physical properties beneath its surface. We propose a method for inferring the thickness and stiffness of a structure from just a video of waves on its […]
Kavli Affiliate: Scott K. Cushing | First 5 Authors: Ayantika Sengupta, Ayantika Sengupta, , , | Summary: Compact, scalable, and multiplexed fluorescence lifetime sensors are of great interest for point-of-care diagnostics. However, current solutions either lack broad-range wavelength-tuning capabilities or involve complex optical setups that hinder miniaturization. On-chip entangled photon sources offer a promising alternative […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Joseph F. V. Allingham, Joseph F. V. Allingham, , , | Summary: Massive galaxy clusters act as prominent strong-lenses. Due to a combination of observational biases, cluster evolution and lensing efficiency, most of the known cluster lenses lie typically at $z_lsim0.2-0.7$, with only a few prominent […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Matilde Brazzini, Matilde Brazzini, , , | Summary: The majority of Little Red Dots (LRDs) hosting Active Galactic Nuclei (AGN) exhibits broad H$alpha$ emission, which recent studies propose originates from scattering off free electrons within an ionized and dense medium embedding the Broad Line Region (BLR), rather […]
Kavli Affiliate: Anthony Challinor | First 5 Authors: Carmen Embil Villagra, Carmen Embil Villagra, , , | Summary: We measure the amplitude of matter fluctuations over a wide range of redshifts by combining CMB lensing observations from ACT DR6 and $textitPlanck$ PR4 with the overdensity of quasars from Quaia, a $textitGaia$ and $textitunWISE$ quasar catalog.
