As usual we watched the "Stoertebekker" stage play at Ralswiek on Rügen Island. The stage setups and wardrobes were as awesome as always. They really try to improve on that every year and come up with clever mechanisms to transform the building for the various acts of the play. The script this year left room for desire ;) Nevertheless a happing worth attending

Adiabatic nonabelian braiding of imperfect Majoranas
Demonstration of a nontrivial result of quasiparticle exchange (or braiding) is usually considered the definitive proof of a topological phase with nonabelian excitations, such as Majorana bound states (MBSs). However, in finite systems with disorder and smooth potential variations, the MBSs are imperfect in the sense that they are not fully isolated in space and can, to a varying degree, resemble conventional fermions. Here, we study the braiding properties of isolated MBSs, regular fermions, …

Vision-driven River Following of UAV via Safe Reinforcement Learning using Semantic Dynamics Model
Vision-driven autonomous river following by Unmanned Aerial Vehicles is critical for applications such as rescue, surveillance, and environmental monitoring, particularly in dense riverine environments where GPS signals are unreliable. We formalize river following as a coverage control problem in which the reward function is submodular, yielding diminishing returns as more unique river segments are visited, thereby framing the task as a Submodular Markov Decision Process. First, we introduce Ma…

An eco-friendly universal strategy via ribavirin to achieve highly efficient and stable perovskite solar cells
The grain boundaries of perovskite films prepared by the solution method are highly disordered, with a large number of defects existing at the grain boundaries. These defect sites promote the decomposition of perovskite. Here, we use ribavirin obtained through bacillus subtilis fermentation to regulate the crystal growth of perovskite, inducing changes in the work function and energy level structure of perovskite, which significantly reduces the defect density. Based on density functional theor…

Moiré dependent Chern insulators in twisted crystalline flatbands
In moiré crystals, the competition between different isospin configurations can be tuned by twist angles and stacking orders, forming various symmetry-broken states. Here we report twisted double rhombohedral-trilayer-gaphene as a new twisted crystalline flatbands system showing rich moiré dependent topological phenomena. For small twist angles, programmable Chern insulators with Chern number C = 3 at integer moiré filling v = 1 have been observed. We have further revealed multiple first-ord…

when it comes to #psychology and #mentalhealth I've read a decent number of #books on the topic.
I think the best I've read are:
- David D. Burns' Feeling Good (CBT generally including anxiety, depression)
- Sue Johnson's Hold Me Tight (romantic/marital relationships)
- Peter Kramer's Against Depression (on why depression is not a creative gift or sign of moral incompetence, biological underpinnings)
Peter Rutter's Sex in the Forbidden Zone has also been instrumental in forming my understanding of the unhealthy ways romantic interest manifests.
Anne Wilson Schaef's Co-Dependence: Misunderstood--Mistreated is the best I've read explaining how "being good" can oftentimes actually be bad.
The latter two are both more things I extract from the books rather than the books themselves and both are couched in ways that make them not ideally suited to the topic...but still the best I've found.
In addition one might include Joel Fuhrman's Eat for Life (I'm reading it now, I originally read Eat to Live) for nutritional health (which affects psychological) and David Allen's Getting Things Done (still one of the most influential books I've read on productivity).
My #question is, are there books you've read that you'd considered "must reads" on psychological / mental health? Not just mental illness, but mental health?

Studies on the effect of low-fluence proton and neutron irradiation on n-type LGADs
The presented study investigates the effects of low fluences from $5\times10^{12}$ up to $1\times10^{14}$ particles/cm$^{2}$ of 60MeV proton and neutron irradiation on n-type Low Gain Avalanche Detectors (nLGADs). An nLGAD is a silicon sensor with a highly doped gain layer that enables controlled charge multiplication via impact ionization. In contrast to the well-established p-type LGADs for high-energy physics (HEP) applications, nLGADs are optimized for the detection of low-penetrating parti…

Grid-Forming Vector Current Control FRT Modes Under Symmetrical and Asymmetrical Faults
Recent research has shown that operating grid-connected converters using the grid-forming vector current control (GFVCC) scheme offers significant benefits, including the simplicity and modularity of the control architecture, as well as enabling a seamless transition from PLL-based grid-following control to grid-forming. An important aspect of any grid-connected converter control strategy is the handling of grid-fault scenarios such as symmetrical and asymmetrical short-circuit faults. This pap…
