High-speed control and navigation for quadrupedal robots on complex and discrete terrain
High-speed legged navigation in discrete and geometrically complex environments is a challenging task because of the high-degree-of-freedom dynamics and long-horizon, nonconvex nature of the optimization problem. In this work, we propose a hierarchical navigation pipeline for legged robots that can traverse such environments at high speed. The proposed pipeline consists of a planner and tracker module. The planner module finds physically feasible foothold plans by sampling-based optimization wi…

Innovative DC-coupled Resistive Silicon Detector for 4D tracking
In the past 10 years, two design innovations, the introduction of low internal gain (LGAD) and of resistive read-out (RSD), have radically changed the performance of silicon detectors. The LGAD mechanism, increasing the signal-to-noise ratio by about a factor of 20, leads to improved time resolution (typically 30 ps for a 50-$μ$m thick sensor), while resistive read-out, sharing the collected charge among read-out electrodes, leads to excellent spatial resolution even using large pixels (about …

#WordWeavers 22/5: If you could magically write a new genre really well, which genre would you choose?
You mean like multi-classing in D&D or do you mean switch genre entirely? I think I'll stick to fantasy, thank you very much. I love my genre, so if I could just get a few levels in "fantasy writing", that'd be great, thank you 🙂

On raconte que les vainqueurs, écrasant la voix de ceux qui ont perdu, écrivent l’Histoire, celle avec un grand H. Un H nettement plus grand que celui, rachitique, de l’innommable.
Comment réagiriez-vous si quelqu’un vous proposait de voir les faits, les approximations, les contre-vérités et les fables sous deux perspectives différentes ?

The Initial Mass Function of Stars and Brown Dwarfs in the Upper Sco Association
I present infrared spectroscopy of 37 brown dwarf candidates in the Upper Sco association, 35 of which are classified as young and cool, making them likely members. This sample includes many of the faintest spectroscopically confirmed members ($K=16$-17 mag), which should have masses down to $\sim0.007$-0.01 $M_\odot$ for the range of ages in Upper Sco (7-14 Myr). Using my updated membership catalog for Upper Sco, I have estimated the initial mass function (IMF) for a field in the center of the…

High-Efficiency Plasma-Based Compressor for Ultrafast Soft X-ray Free-Electron Lasers
The generation of intense, femtosecond-scale X-ray pulses is crucial for probing matter under extreme temporal and field conditions. Current chirped-pulse amplification (CPA) techniques in free-electron lasers (FELs), however, face efficiency limitations in the soft X-ray regime due to the inherent constraints of conventional optical compressors. To address this challenge, we propose a high-efficiency plasma-based compressor utilizing highly ionized noble gas plasma. Exploiting strong refractiv…
