The New Black Hole Solution with Anisotropic Fluid in f(R,Lm, T) Gravity: Thermodynamics
In this work, we derive a new class of analytic black hole solutions within the framework of f(R,Lm, T) gravity, where the black hole is surrounded by an anisotropic fluid acting as the matter source. We consider both linear and nonlinear forms of the function f(R,Lm, T), enabling a detailed exploration of how anisotropic pressures and different f(R,Lm, T) influence the spacetime structure. Furthermore, we derive the conditions on the coupling parameters (\b{eta}1, \b{eta}2, \b{eta}3) under whi…

Propagation of Galactic cosmic rays: the influence of anisotropic diffusion
We investigate the anisotropic diffusion of cosmic rays in the large-scale Galactic magnetic field, where diffusion occurs at different rates along and across the magnetic field lines. To model this process, we use stochastic differential equations to describe cosmic ray propagation and solve them numerically. The Galactic magnetic field is modeled using the Jansson-Farrar prescription. In this study, we focus on the impact of perpendicular diffusion on the residence time of cosmic rays in the …

An LLM's Apology: Outsourcing Awkwardness in the Age of AI
A key part of modern social dynamics is flaking at short notice. However, anxiety in coming up with believable and socially acceptable reasons to do so can instead lead to 'ghosting', awkwardness, or implausible excuses, risking emotional harm and resentment in the other party. The ability to delegate this task to a Large Language Model (LLM) could substantially reduce friction and enhance the flexibility of user's social life while greatly minimising the aforementioned creative burden and mora…

Hardy-Sobolev inequalities involving mixed radially and cylindrically symmetric weights
We deal with weighted Hardy-Sobolev type inequalities for functions on $\mathbb{R}^d$, $d\geq 2$. The weights involved are anisotropic, given by products of powers of the distance to the origin and to a nontrivial subspace. We establish necessary and sufficient conditions for validity of these inequalities, and investigate the existence/nonexistence of extremal functions.

Inside Amsterdam’s high-stakes experiment to create fair welfare AI
The Dutch city thought it could break a decade-long trend of implementing discriminatory algorithms. Its failure raises the question: can these programs ever be fair?

Tunable plasmon modes and topological transitions in single- and bilayer semi-Dirac materials
We investigate the plasmonic response of single- and bilayer semi-Dirac materials under the influence of a tunable parameter $δ$ that governs topological transitions via Dirac cone generation/merging and incorporating band inversion terms. For single-layer systems, we demonstrate that the emergence of Dirac cones leads to an enhanced plasmon frequency range and that the plasmonic spectrum exhibits strong anisotropy, especially for finite $δ$ and vanishing inversion terms. In the bilayer confi…

Permutation-Avoiding FFT-Based Convolution

Permutation-Avoiding FFT-Based Convolution
Fast Fourier Transform (FFT) libraries are widely used for evaluating discrete convolutions. Most FFT implementations follow some variant of the Cooley-Tukey framework, in which the transform is decomposed into butterfly operations and index-reversal permutations. While butterfly operations dominate the floating-point operation count, the memory access patterns induced by index-reversal permutations significantly degrade the FFT's arithmetic intensity. In practice, discrete convolutions are oft…

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?
