Constraints on Ultra Heavy Dark Matter Properties from Dwarf Spheroidal Galaxies with LHAASO Observations

Kavli Affiliate: Zhuo Li | First 5 Authors: Zhen Cao, F. Aharonian, Q. An, Axikegu, Y. X. Bai | Summary: In this work we try to search for signals generated by ultra-heavy dark matter at the Large High Altitude Air Shower Observatory (LHAASO) data. We look for possible gamma-ray by dark matter annihilation or decay […]

Variable recruitment of distal tuft dendrites shapes new hippocampal place fields

Kavli Affiliate: Attila Losonczy and Franck Polleux | Authors: Justin K. O’Hare, Jamie Wang, Margjele D. Shala, Franck Polleux and Attila Losonczy | Summary: Hippocampal pyramidal neurons support episodic memory by integrating complementary information streams into new ‘place fields’. Distal tuft dendrites are widely thought to initiate place field formation by locally generating prolonged, globally-spreading […]

A feedforward mechanism for human-like contour integration

Kavli Affiliate: George A. Alvarez | Authors: Nathan Wu, Baohua Zhou, Margarida Agrochao and Damon A Clark | Summary: Our intuition suggests that when a movie is played in reverse, our perception of motion in the reversed movie will be perfectly inverted compared to the original. This intuition is also reflected in many classical theoretical […]

Warm Hawking Relics From Primordial Black Hole Domination

Kavli Affiliate: Gordan Z. Krnjaic | First 5 Authors: Christopher J. Shallue, Julian B. Muñoz, Gordan Z. Krnjaic, , | Summary: We study the cosmological impact of warm, dark-sector relic particles produced as Hawking radiation in a primordial-black-hole-dominated universe before big bang nucleosynthesis. If these dark-sector particles are stable, they would survive to the present […]

AToM-Bot: Embodied Fulfillment of Unspoken Human Needs with Affective Theory of Mind

Kavli Affiliate: Jia Liu | First 5 Authors: Wei Ding, Fanhong Li, Ziteng Ji, Zhengrong Xue, Jia Liu | Summary: We propose AToM-Bot, a novel task generation and execution framework for proactive robot-human interaction, which leverages the human mental and physical state inference capabilities of the Vision Language Model (VLM) prompted by the Affective Theory […]

Optical Investigations of Coherence and Relaxation Dynamics of a Thulium-doped Yttrium Gallium Garnet Crystal at sub-Kelvin Temperatures for Optical Quantum Memory

Kavli Affiliate: Wolfgang Tittel | Summary:Rare-earth ion-doped crystals are of great interest for quantum memories, a central component in future quantum repeaters. To assess the promise of 1$%$ Tm$^3+$-doped yttrium gallium garnet (Tm:YGG), we report measurements of optical coherence and energy-level lifetimes of its $^3$H$_6$ $leftrightarrow$ $^3$H$_4$ transition at a temperature of around 500 mK […]

The Size-luminosity Relation of the AGN Torus Determined from the Comparison between Optical and Mid-infrared Variability

Kavli Affiliate: Luis C. Ho | First 5 Authors: Minjin Kim, Suyeon Son, Luis C. Ho, , | Summary: We investigate the optical variability of low-redshift ($0.15< zleq0.4$) active galactic nuclei using the multi-epoch data from the Zwicky Transient Facility. We find that a damped random walk model well describes the ensemble structure function in […]
