The THESAN project: Lyman-alpha emitters as probes of ionized bubble sizes

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | Summary:We use the THESAN radiation-hydrodynamics simulations to investigate how Lyman-$α$ emitters (LAEs) trace ionized bubble sizes during the Epoch of Reionization. We generate realistic LAE catalogs by combining accurate intrinsic Ly$α$ production and intergalactic transmission with an empirical model for dust absorption and gas outflows. By calibrating to observationally-constrained Ly$α$ […]

Quadratic Supercontinuum Generation from UV to Mid-IR in Lithium Niobate Nanophotonics

Posted by klaurent Caltech

Kavli Affiliate: Alireza Marandi | Summary:Supercontinuum light sources are widely used for applications ranging from imaging to sensing and frequency comb stabilization. The most common mechanisms for their generation rely on cubic nonlinearities, for instance in crystals, optical fibers, and integrated photonics. However, quadratic supercontinuum generation (QSCG) offers potential for enhanced energy efficiency and broader […]

Memory recall errors reflect interacting sensory and mnemonic representations

Posted by dbos UCSD / Salk

Kavli Affiliate: John Serences | Authors: Holly Kular and John Serences | Summary: Visual working memory (WM) enables the maintenance of information that is no longer present in the environment. Some accounts propose that WM is supported by abstract representations so that new sensory inputs do not interfere with existing memories. Others posit that early […]

Linking Electron Density with Elevated Star Formation Activity from $z=0$ to $z=10$

Posted by klaurent Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Sijia Li, Sijia Li, , , | Summary: The interstellar medium (ISM) in high-redshift galaxies exhibits significantly higher electron densities ($n_rm e$) than in the local universe. To investigate the origin of this trend, we analyze a sample of 9590 centrally star-forming galaxies with stellar masses […]

IF-VidCap: Can Video Caption Models Follow Instructions?

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Shihao Li, Shihao Li, , , | Summary: Although Multimodal Large Language Models (MLLMs) have demonstrated proficiency in video captioning, practical applications require captions that follow specific user instructions rather than generating exhaustive, unconstrained descriptions. Current benchmarks, however, primarily assess descriptive comprehensiveness while largely overlooking instruction-following capabilities. […]

Extinction Coefficients of CdSe, CdS, and CdTe Nanoplatelets in Solution: A Practical Tool for Concentration Determination

Posted by klaurent MIT

Kavli Affiliate: Christopher Burke| First 5 Authors: Michael H. Stewart, Michael H. Stewart, , , | Summary:Semiconductor nanoplatelets possess exceptional optical properties that make them promising candidates for next-generation optoelectronic applications. However, unlike quantum dots where absorption spectroscopy alone can determine both size and concentration, nanoplatelets present a significant characterization challenge: the absorption peak position […]

Effects of Virtual Controller Representation and Virtuality on Selection Performance in Extended Reality

Posted by klaurent MIT

Kavli Affiliate: Rob Simcoe | First 5 Authors: Eric DeMarbre, Eric DeMarbre, , , | Summary: We present an experiment exploring how the controller’s virtual representation impacts target acquisition performance across MR and VR contexts. Participants performed selection tasks comparing four visual configurations: a virtual controller, a virtual hand, both the controller and the hand, […]

Every Benchmark All at Once

Posted by klaurent Delft

Kavli Affiliate: Eliska Greplova | Summary:As quantum technology matures, the efficient benchmarking of quantum devices remains a key challenge. Although sample-efficient, information-theoretic benchmarking techniques have recently been proposed, there is still a gap in adapting these techniques to contemporary experiments. In this work, we re-formulate five of the most common randomized benchmarking techniques in the […]

Chain-of-Conceptual-Thought Elicits Daily Conversation in Large Language Models

Posted by klaurent Cornell

Kavli Affiliate: Dan Luo | First 5 Authors: Qingqing Gu, Qingqing Gu, , , | Summary: Chain-of-Thought (CoT) is widely applied to enhance the LLM capability in math, coding and reasoning tasks. However, its performance is limited for open-domain tasks, when there are no clearly defined reasoning steps or logical transitions. To mitigate such challenges, […]
