With the advent of ELIZA, Joseph Weizenbaum's first psychotherapist chatbot, NLP took another major step with pattern-based substitution algorithms based on simple regular expressions.

I found this today when messing around with lifting-bits/sleigh build options and got a build error. Very interesting! Dynamic p-code shenanigans!
“TLDR: there is a (undocumented and disabled by default) feature in the Ghidra decompiler that lets you create your own decompiler passes, using a custom DSL. I leverage it to write a deobfuscation rule for a simple obfuscation technique.”
Thanks you @…

Not sure if those work with a prepaid sim card on a modem (nor if it’s legal to setup such an answering machine on one of them here), but I’ll do some research on it
As for voip numbers, no idea how those work and if they’re universal or if I have to get one from a provider explicitly made for Asterisk compatibility, but they seem quite expensive (specially since the prepaid ones would be basically free since it’s only for receiving calls from nerds, not making calls) anyway.

An Open-source Capping Machine Suitable for Confined Spaces
In the context of self-driving laboratories (SDLs), ensuring automated and error-free capping is crucial, as it is a ubiquitous step in sample preparation. Automated capping in SDLs can occur in both large and small workspaces (e.g., inside a fume hood). However, most commercial capping machines are designed primarily for large spaces and are often too bulky for confined environments. Moreover, many commercial products are closed-source, which can make their integration into fully autonomous wo…

K2 observations of five pulsating subdwarf B stars with white dwarf companions
We report seismic analyses of five pulsating subdwarf B (sdBV) stars observed during Kepler's K2 mission, each with a white dwarf companion. We find three of the five to be g-mode-dominated hybrid pulsators. For the other two, we only detect g modes. We determine rotation periods from frequency multiplets for four stars and each rotates subsynchronously to its binary period, including PG 0101+039 and PG 0902+124 both with binary periods near 0.57 days and spin periods near 9 days. We detect fre…

Emergence of thermodynamic functioning regimes from finite coupling between a quantum thermal machine and a load
Autonomous quantum thermal machines are particularly suited to understand how correlations between thermal baths, a load, and a thermal machine affect the overall thermodynamic functioning of the setup. Here, we show that by tuning the operating temperatures and the magnitude of the coupling between machine and load, the thermal machine can operate in four modes: engine, accelerator, heater, or refrigerator. In particular, we show that as we increase the coupling strength, the engine mode is su…

An Augmented Lagrangian Preconditioner for Navier--Stokes Equations with Runge--Kutta in Time
We consider a Runge--Kutta method for the numerical time integration of the nonstationary incompressible Navier--Stokes equations. This yields a sequence of nonlinear problems to be solved for the stages of the Runge--Kutta method. The resulting nonlinear system of differential equations is discretized using a finite element method. To compute a numerical approximation of the stages at each time step, we employ Newton's method, which requires the solution of a large and sparse generalized saddl…

Detailed Time Resolved Spectral and Temporal Investigations of SGR J1550-5418 Bursts Detected with Fermi/Gamma-ray Burst Monitor
We have conducted a time-resolved spectral analysis of magnetar bursts originating from SGR J1550-5418. Our analysis utilizes a two-step methodology for temporal segmentation of the data. We first generated and fitted overlapping time segments. Subsequently, we obtained non-overlapping time segments with varying lengths based on their spectral evolution patterns, employing a machine learning algorithm called k-means clustering. For the fitting process, we employed three distinct models, namely …

Mitigation of the Flexing-Filtering Effect in Time-Delay Interferometry
In early 2024, ESA formally adopted the Laser Interferometer Space Antenna (LISA) space mission with the aim of measuring gravitational waves emitted in the millihertz range. The constellation employs three spacecraft that exchange laser beams to form interferometric measurements over a distance of 2.5 million kilometers. The measurements will then be telemetered down to Earth at a lower sampling frequency. Anti-aliasing filters will be used on board to limit spectral folding of out-of-band las…
