Shedding light on the star formation rate-halo accretion rate connection and halo quenching mechanism via DECODE, the Discrete statistical sEmi-empiriCal mODEl

Posted by dbos February 10, 2025February 24, 2025Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Hao Fu, Lumen Boco, Francesco Shankar, Andrea Lapi, Mohammadreza Ayromlou | Summary: Aims: The relative roles of the physical mechanisms involved in quenching galaxy star formation are still unclear. We tackle this fundamental problem with our cosmological semi-empirical model DECODE (Discrete statistical sEmi-empiriCal mODEl), designed to predict […]

Nonrenormalization Theorem for ${cal N}=(4,4)$ Interface Entropy

Posted by dbos February 10, 2025February 24, 2025Tokyo

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Andreas Karch, Hirosi Ooguri, Mianqi Wang, , | Summary: We derive a formula for the half-BPS interface entropy between any pair of ${cal N}=(4,4)$ theories on the same conformal manifold. This generalizes the diastasis formula derived in arXiv:1311.2202 for ${cal N}=(2,2)$ theories, which is restricted to the […]

Evolving dark energy models: Current and forecast constraints

Posted by dbos February 10, 2025February 24, 2025Chicago

Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Anowar J. Shajib, Joshua A. Frieman, , , | Summary: Recent results from Type Ia supernovae (SNe Ia) and baryon acoustic oscillations (BAO), in combination with cosmic microwave background (CMB) measurements, have focused renewed attention on dark energy models with a time-varying equation-of-state parameter, $w(z)$. In […]

Heisenberg-limited calibration of entangling gates with robust phase estimation

Posted by dbos February 10, 2025February 24, 2025Berkeley

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Kenneth Rudinger, J. P. Marceaux, Akel Hashim, David I. Santiago, Irfan Siddiqi | Summary: The calibration of high-quality two-qubit entangling gates is an essential component in engineering large-scale, fault-tolerant quantum computers. However, many standard calibration techniques are based on randomized circuits that are only quadratically sensitive to […]

Reconstructing the shape of the non-linear matter power spectrum using CMB lensing and cosmic shear

Posted by dbos February 10, 2025February 24, 2025Cambridge

Kavli Affiliate: Blake Sherwin | First 5 Authors: Karen Perez Sarmiento, Alex Laguë, Mathew Madhavacheril, Bhuvnesh Jain, Blake Sherwin | Summary: We reconstruct the non-linear matter power spectrum $P(k)$ using a joint analysis of gravitational lensing of the cosmic microwave background (CMB) and lensing of galaxies. This reconstruction is motivated by the $S_8$ tension between […]

Simulation as Reality? The Effectiveness of LLM-Generated Data in Open-ended Question Assessment

Posted by dbos February 10, 2025February 24, 2025UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Long Zhang, Meng Zhang, Wei Lin Wang, Yu Luo, | Summary: The advancement of Artificial Intelligence (AI) has created opportunities for e-learning, particularly in automated assessment systems that reduce educators’ workload and provide timely feedback to students. However, developing effective AI-based assessment tools remains challenging due to […]

Impact of mass transfer on the orbital evolution of a white dwarf close to an intermediate-mass black hole

Posted by dbos February 10, 2025Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Yang Yang, Jie Yang, Xian Chen, Zihan Zhang, | Summary: Extreme mass ratio inspiral (EMRI) systems composed of low-mass white dwarfs (WDs, $0.1 – 0.3$ $mathrm{M}_{odot } $) and intermediate-mass black holes (IMBHs, $10^{3} – 10^{5}$ $mathrm{M}_{odot } $) are ideal objects for multi-messenger astronomy because they […]

Sweeps in space: leveraging geographic data to identify beneficial alleles in Anopheles gambiae

Posted by dbos February 9, 2025February 19, 2025Columbia

Kavli Affiliate: Scott Small | Authors: Clara T Rehmann, Scott T Small, Peter L Ralph and Andrew D. Kern | Summary: As organisms adapt to environmental changes, natural selection modifies the frequency of non-neutral alleles. For beneficial mutations, the outcome of this process may be a selective sweep, in which an allele rapidly increases in […]

Delta — Contrastive Decoding Mitigates Text Hallucinations in Large Language Models

Posted by dbos February 9, 2025UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng Huang, Hao-Yuan Chen, , , | Summary: Large language models (LLMs) demonstrate strong capabilities in natural language processing but remain prone to hallucinations, generating factually incorrect or fabricated content. This issue undermines their reliability, particularly in high-stakes domains such as healthcare and legal advisory. To […]

The SUPERCOLD-CGM survey: II. [ion{C}{1}]$(1-0)$ emission and the physical conditions of cold gas in Enormous Ly$α$ nebulae at $z,sim,2$

Posted by dbos Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Jianan Li, Bjorn H. C. Emonts, Zheng Cai, Jianrui Li, Ran Wang | Summary: We report ALMA and ACA observations of atomic carbon ([ion{C}{1}]$(1-0)$) and dust continuum in 10 Enormous Ly$alpha$ Nebulae hosting ultra-luminous Type-I QSOs at $z=2.2-2.5$, as part of the SUrvey of Protocluster ELANe Revealing […]
