🏡 Here is the data analysis for Calgary, Summer 2025. This chart shows the relationship between vegetation density (NDVI) and Land Surface Temperature (LST).
🔥 The data reveals a critical "tipping point": vegetation only starts effectively cooling the environment once it reaches a specific density threshold. Below this threshold (the left side of the curve), green spaces stay just as hot as the surrounding concrete.
Sparse or isolated trees don't act as air conditioners—they "burn" in the urban furnace right along with us.
❗ What does this mean for Calgary? Simply planting a few scattered trees isn't enough. To actually move the needle on temperature, we need dense, healthy green belts. Otherwise, it’s just a waste of water and resources.

RE: https://fediscience.org/@snakemake/116295568336688286
This is a big step forward: The SLURM plugin for Snakemake now supports so-called job arrays. These are cluster jobs, with ~ equal resource requirements in terms of memory and compute resources.
The change in itself was big: The purpose of a workflow system is to make use of the vast resources of an HPC cluster. Hence, jobs are submitted to run concurrently. However, for a job array, we have to "wait" for all eligible jobs to be ready. And then we submit.
To preserve concurrent execution of other jobs which are ready to be executed, a thread pool has been introduced. In itself, I do not see job arrays such a big feature: The LSF system profited much more from arrays than the rather lean SLURM implementation does.
BUT: the new code base will ease further development to pooling many shared memory tasks (applications which support no parallel execution or are confined to one computer by "only" supporting threading). Until then, there is more work to do.

One more quick byproduct of my MDEM development: a bivariate map integrating volumetric structural data (SAR) with surface temperature (LST). This approach identifies the exceptionally intensive dissipative role of volumetric vegetation structure (trees and tall shrubs). By accounting for these high-performance cooling elements, we can better understand how they supplement traditional landscaping to enhance the city's overall thermal resilience.

⚠️ Call for participation ⚠️
If you are an archaeologist working with #3D, I'd be super grateful if you dedicate 15 minutes of your time to answer this survey.
It's part of my #PhD research and will bring a clearer picture of how archaeologists use 3D tools and data.

Update. New study: At least in #Germany, in the field of #economics, "men tend to seek reputation, while women favor visibility through #OpenAccess…Overall female researchers appear to contribute more to the public good of #OpenScience, while their male colleagues focus on private reputation. These findings may offer an additional explanatory channel for the academic #gender gap."

🧪 The “Oversaturation Illusion” in Kryvbas Mine Waters
While modeling Kryvbas water chemistry (R + PHREEQC), I found a fundamental issue in how saturation is often evaluated.
We usually calculate calcite equilibrium from ion concentrations — fine for fresh water.
But Kryvbas mine waters are brines, where ionic strength and complexation dominate.
📉 Results from ~1000 samples (minteq.v4):
- Once salinity exceeds ~3 g/L, Ca²⁺ activity drops sharply.
- At 15–20 g/L, calcium activity coefficient is ≈ 0.35.
Meaning: more than half of the “calcium concentration” is inert — a dead load that cannot form precipitates.
This explains why traditional methods predicted oversaturation where the water was actually aggressive and dissolving rocks.
Modeling: PHREEQC + minteq.v4 (US EPA), Davis equation.
