Minimal Neuron Circuits -- Part I: Resonators
Spiking Neural Networks have earned increased recognition in recent years owing to their biological plausibility and event-driven computation. Spiking neurons are the fundamental building components of Spiking Neural Networks. Those neurons act as computational units that determine the decision to fire an action potential. This work presents a methodology to implement biologically plausible yet scalable spiking neurons in hardware. We show that it is more efficient to design neurons that mimic …

Spegion: Implicit and Non-Lexical Regions with Sized Allocations
Region based memory management is a powerful tool designed with the goal of ensuring memory safety statically. The region calculus of Tofte and Talpin is a well known example of a region based system, which uses regions to manage memory in a stack-like fashion. However, the region calculus is lexically scoped and requires explicit annotation of memory regions, which can be cumbersome for the programmer. Other systems have addressed non-lexical regions, but these approaches typically require the…

Does anyone have suggested spacing guidelines for Molex PicoBlade connectors oriented in a row so that the cables run over each other?
Obviously the three shown here are too close.
But how far apart is far enough?

Characterization of the VKI Plasmatron subsonic ICP jet combining optical emission spectroscopy, intrusive measurements, and CFD simulations
This paper addresses the characterization of the subsonic flow in the 1.2~MW Inductively Coupled Plasma (ICP) wind tunnel at the von Karman Institute for Fluid Dynamics (VKI), targeting chamber pressures of 50 and 100~mbar, and input electric powers between 150 and 300~kW. Ultraviolet to near-infrared optical emission spectroscopy measurements of the free-jet flow are carried out with an updated experimental set-up, calibration procedure, and data processing, providing high-quality absolute spa…

A tactic long used by the #CCP against the family members of #Tibetan, #uyghur and other dissidents who have spoken out from abroad, has finally come to

For this week's #MusicWomenWednesday, something with some real female RAGE. For the last couple days since it came out, I've been thoroughly enjoying Kitchener, Ontario's hardcore quintet BODY MINUS HEAD's debut LP 'An Exercise in Self-Sufficiency'. The whole band is tight and solid, but vocalist Alexandra Garvin really shines on this one. Her screams are unreal, and at …

Been thinking about getting a proper family computer, something more than the kids’ Chromebook and my wife’s old dying MacBook. A Mac Mini should be sufficient, right?
I think I need to pull the trigger before prices get adjusted for tariffs

SpiceMixer - Netlist-Level Circuit Evolution
This paper introduces SpiceMixer, a genetic algorithm developed to synthesize novel analog circuits by evolving SPICE netlists. Unlike conventional methods, SpiceMixer operates directly on netlist lines, enabling compatibility with any component or subcircuit type and supporting general-purpose genetic operations. By using a normalized netlist format, the algorithm enhances the effectiveness of its genetic operators: crossover, mutation, and pruning. We show that SpiceMixer achieves superior pe…
