Are there any admins on social.tchncs.de.? Is anonymously spreading lies about over 30 families in Gaza allowed on this instance?
This anonymous coward has been chased off of every server he’s been on and yet he’s still here, still attacking people suffering from genocide and famine.
(And yes, some folks copy posts from others. We’ve asked them not to. But they’re trying to survive genocide, not win social media awards.)
Also (see his second post) we’re not attempting to r…

Linux Is Best (@Linux@social.tchncs.de)
Attached: 2 images 1 of 2 First, let me say: what’s happening in Gaza is absolutely awful. But what’s also awful is that there are dishonest people taking advantage of others during a crisis. In one photo, from Facebook (my job, where I work), we had a woman claiming to be a 36-year-old mother of two children, ages 4 and 7. She spaced out the URL in her post, hoping it wouldn’t get flagged by spam filters (it did). The very next day, someone on the Fediverse posted the exact same messa…

Symbols from Bi-Projections
We initiate a systematic framework for the analysis of analytic properties of finite Feynman integrals that are multiple polylogarithms. Based on the Feynman parameter representation in complex projective space, we make a complete classification of logarithmic singularities of the integral on its principal branch, by what we call touching configurations -- a geometric relationship between the integrand singularity and linear subspaces tied to boundary elements of the integral contour. These on …

Posting this, I idly looked up “folly”; I already knew about them as an affectation, what I did NOT know, was that during the Great Famine in Ireland, follies were built to pay people without “taking work away from workers on actual projects”.
Wouldn’t wanna just GIVE starving people money, eh?🙄 https://mastodon.social…

Fokker-Planck equation for stochastic heat equations
This work is devoted to the study of the Fokker--Planck equation for a stochastic heat equation with an additive $Q$-Wiener noise and non-homogeneous boundary conditions. We explicitly construct the probability density function and establish the associated Fokker--Planck equation by applying the eigenfunction expansion technique. Moreover, the Feynman--Kac formula is used to obtain the probabilistic representation of the solution. The analysis is further extended to cases with multiplicative no…

Knots and variance ordering of sequential Monte Carlo algorithms
Sequential Monte Carlo algorithms, or particle filters, are widely used for approximating intractable integrals, particularly those arising in Bayesian inference and state-space models. We introduce a new variance reduction technique, the knot operator, which improves the efficiency of particle filters by incorporating potential function information into part, or all, of a transition kernel. The knot operator induces a partial ordering of Feynman-Kac models that implies an order on the asymptot…

Feynman-Kac formula gor general time dependent stochastic parabolic equation on a bounded domain and applications
This paper establishes a Feynman-Kac formula to represent the solution to general time inhomogeneous stochastic parabolic partial differential equations driven by multiplicative fractional Gaussian noises in bounded domain where L_t is a second order uniformly elliptic operator whose coefficients can depend on time and generates a time inhomoegenous Markov process. The idea is to use the Aronson bounds of fundamental solution of the associated heat kernel and the techniques from Malliavin calcu…

Anti-de Sitter, plane waves and quantum field theory
We present a new plane-wave expansion of the Wightman functions of anti de Sitter scalar fields and showcase its conceptual and technical importance in AdS quantum field theory. We deduce from it a new integral representation of the Feynman propagator which helps in clarifying the relation between AdS Euclidean and Lorentzian Feynman diagrams in concrete examples. The plane-wave expansion makes it possible also to demonstrate numerous new nontrivial formulas for Bessel and Legendre functions, a…

Jetzt habe ich mich gerade zum ersten Mal unberechtigterweise über mein #PaperTablet #reMarkablePro geärgert, weil ich mit #eBooks kaufen wollte, die einen #Kopierschutz für #DRM haben. Auf dem reMarkable kann ich diese elende Adope-App nicht installieren, mit der ich eine Adope-ID erstellen und so die eBooks überhaupt erst öffnen könnte. Als Ratschlag, der für mich allerdings auch ein Augenthema ist, wäre, eine entsprechende App auf meinem Android-Tablet zu installieren. Nur ist das deutlich kleiner, spürbar schwerer und das Display sehr viel heller (was ein Lesen im Bett, während mein Herzensmensch neben mir schon schlummert, unmöglich macht), nicht matt und draußen auf dem Balkon lesen, wenn die Sonne scheint, würde auch schwierig werden.
Entweder war ich seither nur in Nieschen unterwegs, in denen solche Schutzvorrichtungen nicht nötig sind, oder die Verlage fangen jetzt erst so richtig damit an und ich werde zukünftig dann wohl nur noch sehr selten komfortabel lesen (und mir Notizen machen) können.
Übertragungserkenntnis: wenn ich als #ADHS-ler, für den die Texteinstellungsmöglichkeiten bei eBooks eine enorme Energieersparnis und Lernqualität bedeuten, schon so in diese #WalledGarden-Dinge gedrängt werde, wie heftig ist das dann für Menschen, die vollkommen Abhängig von diversen Hilfen und Unterstützungen sind?
reMarkable selbst kann ich da keinen Vorwurf machen, denke ich.
