Structural Separation and Semantic Incompatibility in the P vs. NP Problem: Computational Complexity Analysis with Construction Defining Functionality
The Boolean satisfiability problem (SAT) holds a central place in computational complexity theory as the first shown NP-complete problem. Due to this role, SAT is often used as the benchmark for polynomial-time reductions: if a problem can be reduced to SAT, it is at least as hard as SAT, and hence considered NP-complete. However, the CDF framework offers a structural inversion of this traditional view. Rather than treating SAT as merely a representative of NP-completeness, we investigate wheth…

Spectral Masking and Interpolation Attack (SMIA): A Black-box Adversarial Attack against Voice Authentication and Anti-Spoofing Systems
Voice Authentication Systems (VAS) use unique vocal characteristics for verification. They are increasingly integrated into high-security sectors such as banking and healthcare. Despite their improvements using deep learning, they face severe vulnerabilities from sophisticated threats like deepfakes and adversarial attacks. The emergence of realistic voice cloning complicates detection, as systems struggle to distinguish authentic from synthetic audio. While anti-spoofing countermeasures (CMs) …

Well I still suck at it, but thus far I'm really happy with the 1.0.1 build of FreeCAD. They simplified the build procedure so you don't have to keep bouncing between Sketch mode and Part mode. I even figured out how to cut multiple sketches into a part, and the auto-constraint feature is pretty useful.
Progress on this Heltec case is progressing slowly, but it's coming along.
As a side note, I'm starting to see why folks are installing transistors on their GPS …

An Analytical Approach to Privacy and Performance Trade-Offs in Healthcare Data Sharing
The secondary use of healthcare data is vital for research and clinical innovation, but it raises concerns about patient privacy. This study investigates how to balance privacy preservation and data utility in healthcare data sharing, considering the perspectives of both data providers and data users. Using a dataset of adult patients hospitalized between 2013 and 2015, we predict whether sepsis was present at admission or developed during the hospital stay. We identify sub-populations, such as…
