"[…] Wanting a man got me into awful troubles more than once. But wanting to get married, never! No, no. None of that for me."
"Why not?" Tenar demanded.
Taken aback, Moss said simply, "Why, what man'd marry a witch?" And then, with a sidelong chewing motion of her jaw, like a sheep shifting its cud, “And what witch’d marry a man?"
They split rushes.
"What's wrong with men?" Tenar inquired cautiously.
As cautiously, lowering her voice, Moss replied, "I don't know, my dearie. I’ve thought on it. Often I’ve thought on it. The best I can say it is like this. A man’s in his skin, see, like a nut in its shell." She held up her long, bent, wet fingers as if holding a walnut. “It’s hard and strong, that shell, and it’s all full of him. Full of grand man-meat, man-self. And that’s all. That’s all there is. It’s all him and nothing else, inside."
Tenar pondered awhile and finally asked, "But if he's a wizard—"
"Then it's all his power, inside. His power’s himself, see. That’s how it is with him. And that’s all. When his power goes, he’s gone. Empty." She cracked the unseen walnut and tossed the shells away. “Nothing."
"And a woman, then?"
"Oh, well, dearie, a woman's a different thing entirely. Who knows where a woman begins and ends? Listen, mistress, I have roots, I have roots deeper than this island. Deeper than the sea, older than the raising of the lands. I go back into the dark." Moss’s eyes shone with a weird brightness in their red rims and her voice sang like an instrument. “I go back into the dark! Before the moon I was. No one knows, no one knows, no one can say what I am, what a woman is, a woman of power, a woman’s power, deeper than the roots of trees, deeper than the roots of islands, older than the Making, older than the moon. Who dares ask questions of the dark? Who’ll ask the dark its name?"

Why M-dwarf flares have limited impact on sub-Neptunes' atmospheric evaporation
M-type stars are prime targets for exoplanet searches within their habitable zones (HZs). M-type stars also exhibit significant magnetic flaring activity, especially during the first billion years, which can potentially accelerate the evaporation of the hydrogen-helium envelopes of close-in planets. We use the time-dependent photo-ionization hydrodynamics code ATES to investigate the impact of flares on atmospheric escape, focusing on a sub-Neptune-sized planet orbiting an early M-type star at …

Measurement of radionuclide production probabilities in negative muon nuclear capture and validation of Monte Carlo simulation model
As part of the development of a sample radioactivity calculation program, we have measured radionuclide production probabilities in negative muon nuclear capture to update experimental data and to validate a calculation dataset obtained by a Monte Carlo simulation code. The probabilities have been obtained by an activation experiment on $^{27}$Al, $^\mathrm{nat}$Si, $^{59}$Co, and $^\mathrm{nat}$Ta targets. The obtained probabilities expand the validation scope to the radionuclide production pr…

Comparing observations of the closely located JUICE and STEREO-A spacecraft during the widespread solar energetic particle event of 2024 May 13
JUICE was launched in April 2023, and it is now in its cruise phase to Jupiter, where it is scheduled to arrive in July 2031. JUICE carries a radiation monitor, namely the RADiation hard Electron Monitor (RADEM) to measure protons, electrons, and ions, detecting particles coming mainly from the anti-Sun direction. On 2024 May 13, a large solar energetic particle (SEP) event took place in association with an eruption close to the western limb of the Sun as seen from Earth. Providentially, at tha…

Why I Gave Up My Smartwatch
Somewhere between the first time I tapped my wrist to skip a song and the three hundredth time I anxiously checked my resting heart rate, I started to hate my Apple Watch. The promise of the smartwatch was elegance, convenience, optimization. What I got was constant data drip, subtle panic,

FAUST XXVI. The dust opacity spectral indices of protostellar envelopes bridge the gap between interstellar medium and disks
The sub-millimetre dust opacity spectral index is a critical observable to constrain dust properties, such as the maximum grain size of an observed dust population. It has been widely measured at galactic scales and down to protoplanetary disks. However, because of observational and analytical challenges, quite a gap exists in measuring dust properties in the envelopes that feed newborn protostars and their disks. To fill this gap, we use sensitive dust continuum emission data at 1.2 and 3.1 mm…

Robust and Safe Multi-Agent Reinforcement Learning Framework with Communication for Autonomous Vehicles
Deep multi-agent reinforcement learning (MARL) has been demonstrated effectively in simulations for many multi-robot problems. For autonomous vehicles, the development of vehicle-to-vehicle (V2V) communication technologies provide opportunities to further enhance safety of the system. However, zero-shot transfer of simulator-trained MARL policies to hardware dynamic systems remains challenging, and how to leverage communication and shared information for MARL has limited demonstrations on hardw…

Complexity of Firefighting on Graphs
We consider a pursuit-evasion game that describes the process of extinguishing a fire burning on the nodes of an undirected graph. We denote the minimum number of firefighters required by $\text{ffn}(G)$ and provide a characterization for the graphs with $\text{ffn}(G)=1$ and $\text{ffn}(G)=2$ as well as almost sharp bounds for complete binary trees. We show that deciding whether $\text{ffn}(G) \leq m$ for given $G$ and $m$ is NP-hard. Furthermore, we show that shortest strategies can have supe…
