Detecting Atmospheric CO2 Trends as Population-Level Signatures for Long-Term Stable Water Oceans and Biotic Activity on Temperate Terrestrial Exoplanets
Identifying key observables is essential for enhancing our knowledge of exoplanet habitability and biospheres, as well as improving future mission capabilities. While currently challenging, future observatories such as the Large Interferometer for Exoplanets (LIFE) will enable atmospheric observations of a diverse sample of temperate terrestrial worlds. Using thermal emission spectra that represent conventional predictions of atmospheric CO2 variability across the Habitable Zone (HZ), we assess…

Si(100)-SiO$_2$ Trap Density Dependence on Sample Processing
As silicon-based devices continue to shrink to the nanoscale, traps at the Si-SiO$_2$ interface pose increasing challenges to device performance. These traps reduce channel carrier mobility and shift threshold voltages in integrated circuits, and introduce charge noise in quantum systems, reducing their coherence times. Knowledge of the precise location of such traps aids in understanding their influence on device performance. In this work, we demonstrate that frequency-modulated atomic force m…

Me in GNU Prolog:
```
?- X is 3 - 2

Why is it taking so much time to answer this simple question? Then I realised I forgot the period. After adding the it, gprolog responds,
```
X = 1
yes
```
satisfaction!

Regional chemical potential analysis for material surfaces
We propose a local regional chemical potential (RCP) analysis method based on an energy window scheme to quantitatively estimate the selectivity of atomic and molecular adsorption on surfaces, as well as the strength of chemical bonding forces between a probe tip and a surface in atomic force microscopy (AFM) measurements. In particular, focusing on the local picture of covalent bonding, we use a simple H$_2$ molecular model to demonstrate a clear relationship between chemical bonding forces an…

The Optical Design of the Carbon Investigation(Carbon-I) Imaging Spectrometer
The proposed Carbon Investigation (Carbon-I) Imaging Spectrometer is designed to measure variations of greenhouse gases in Earth's atmosphere. The instrument will survey the Earth from its own spacecraft at an altitude of approximately 610 km. It will use a coarse ground sampling distance (GSD) of <400 m in global mode for land and coastal monitoring and finer 35 m GSD in target mode to sample key regions. The identification and quantification of greenhouse gases require continuous spectral sam…

Apax: A Flexible and Performant Framework For The Development of Machine-Learned Interatomic Potentials
We introduce Atomistic learned potentials in JAX (apax), a flexible and efficient open source software package for training and inference of machine-learned interatomic potentials. Built on the JAX framework, apax supports GPU acceleration and implements flexible model abstractions for fast development. With features such as kernel-based data selection, well-calibrated uncertainty estimation, and enhanced sampling, it is tailored to active learning applications and ease of use. The features and…

One of the most important lessons I've learned in life / continue to learn / managed to forget is the importance of "stopping." It is so easy for life to become overwhelming with all the things I must do. Work, family, friends, volunteering, community, finances, chores, taking care of my health, the list goes on...
"Life is a very simple thing. We make it more complex." - Anonymous
"When we are making our life more complex, that is precisely the time when we are totally incapable of seeing what we are doing. The more complex our lives are, the more we need to be present to them and, surprisingly, this is exactly the time when we are most distracted. When we are distracted, we tend to have poor judgment and make more mistakes . . . usually adding to the confusion . . . and so it goes."
"....We usually respond by trying to become even more controlling and, eventually (or immediately!), this just makes things worse."
"It's time to stop, take stock, take some deep breaths, rest, listen to others, and regroup...We may miss something. We may even miss something we think is important. That's okay. We're more important."
"Taking time to stop may be just what I need to move ahead."
