Wenn ich die CDU Hessen richtig verstanden habe, möchte sie den Mangel an Therapieplätzen für psychisch Erkrankte dadurch beheben, daß Menschen sich keine Hilfe mehr suchen, sondern einfach still leiden (oder irgendwann sich selbst oder anderen Gewalt antun, weil sie nicht mehr anders können), damit sie nicht auf den berüchtigten Listen der Polizei landen.¹
Das ist nicht nur unmenschlich, sondern auch dumm und gefährlich.

Diagnosing the impact of relativistically intense prepulse on few-picosecond timeframes for short scale length laser-matter interactions
With the rapid proliferation of multi-petawatt (MPW) lasers globally, a new era of high-energy density science promises to emerge within the next decade. However, precise control over how light at these ultra-relativistic intensities interacts with matter (especially with solid-density targets) will be crucial to fully realize the cutting-edge scientific advancements and technological breakthroughs that the MPW regime promises to unlock. In this manuscript, we present experimental results, supp…

What does making money have to do with crime?: A dive into the National Crime Victimization survey
In this short article, I leverage the National Crime Victimization Survey from 1992 to 2022 to examine how income, education, employment, and key demographic factors shape the type of crime victims experience (violent vs property). Using balanced classification splits and logistic regression models evaluated by F1-score, there is an isolation of the socioeconomic drivers of victimization "Group A" models and then an introduction of demographic factors such as age, gender, race, and marital stat…

Three regimes of a picosecond magnetoacoustics in ferromagnetic structures
The development of magnonics requires energy-efficient methods for generating spin waves and controlling their parameters. Acoustic waves are known to resonantly excite spin waves through magneto-elastic wave formation or to induce non-resonant forced magnetization oscillations. Short acoustic wavepackets enable another unexplored resonant interaction regime -- the Cherenkov radiation of spin waves. This raises a question regarding the criteria and signatures of these three regimes of picosecon…

Discovery and study of the eclipsing variable star Grigoriev 1
This work is dedicated to the discovery of the eclipsing variable star Grigoriev 1 and determining the parameters of its binary system. The star was found through the systematic checking of ultraviolet sources of GALEX space observatory in Pegasus constellation. Analysis of the ZTF project data has shown the presence of eclipses with two magnitudes depth and a period of 6.5997 days. The duration of eclipse covers only 1% of the orbital period, and the partial phases are at least 30 times shorte…

This short paper gets deep in the weeds of a particular kind of physics, he is sharing a rare example where we were able to both reduce a system and then construct the aggregate behavior. But the broad systems conclusion is what's interesting.
The arrogance of the particle physicist and his intensive research may be behind us (the discoverer of the positron said "the rest is chemistry"), but we have yet to recover from that of some molecular biologists, who seem determined to try to reduce everything about the human organism to "only" chemistry, from the common cold and ailmental disease to the religious instinct. Surely there are more levels of organization between human ethology and DNA than there are between DNA and quantum electrodynamics, and each level can require a whole new conceptual structure.

Numerical simulations of electron acceleration driven by heavy ion beams in plasma with alternating density gradients
Plasma-Based Acceleration (PBA) has been demonstrated using laser, electron, and proton drivers. However, significant challenges remain in achieving high efficiency, stable acceleration, and scalable energy gain. Heavy ion beam drivers, with their high kinetic energy, offer the potential for greater energy transfer to the witness beam. Unfortunately, limited by the relatively low velocity of heavy ion, the dephasing length is really short leading to a low energy gain of the witness beam. Conven…

Pinsker's inequality for adapted total variation
Pinsker's classical inequality asserts that the total variation $TV(μ, ν)$ between two probability measures is bounded by $\sqrt{ 2H(μ|ν)}$ where $H$ denotes the relative entropy (or Kullback-Leibler divergence). Considering the discrete metric, $TV$ can be seen as a Wasserstein distance and as such possesses an adapted variant $ATV$. Adapted Wasserstein distances have distinct advantages over their classical counterparts when $μ, ν$ are the laws of stochastic processes $(X_k)_{k=1}^…

The Multiverse: a Philosophical Introduction
This book is a philosopher's introduction to the idea that our universe is just one of many universes. I present and assess three versions of the idea: one version from philosophy, and two from physics. In short, they are: all the logically possible worlds; all the branches of the quantum state, in an Everettian interpretation of quantum theory; and all the bubbles of inflationary cosmology. For each proposal, I choose one main philosophical question to discuss in depth. They are, respectively:…

Optical force density and surface displacements in transparent dielectrics due to non-ionizing sub-picosecond laser excitation
The optical force density acting in transparent dielectric media due to short laser excitation is theoretically analyzed. For typical laser pulses with picosecond duration, the momentum component of the optical force becomes of the same order of magnitude as the stress component, enhancing the overall optomechanical effects. Simulations of the optically-induced surface displacements in fused silica glass are also presented. With careful choice of realistic simulation parameters, dispersive and …
