Automated Mechanism to Support Trade Transactions in Smart Contracts with Upgrade and Repair
In our previous research, we addressed the problem of automated transformation of models, represented using the business process model and notation (BPMN) standard, into the methods of a smart contract. The transformation supports BPMN models that contain complex multi-step activities that are supported using our concept of multi-step nested trade transactions, wherein the transactional properties are enforced by a mechanism generated automatically by the transformation process from a BPMN mode…

Transformation formula of Dwork's $p$-adic hypergeometric function

Transformation formula of Dwork's $p$-adic hypergeometric function
In this paper, we give a transformation formula of Dwork's $p$-adic hypergeometric function between $t$ and $t^{-1}$. As an appendix, we introduce a finite analogue of this transformation formula, which implies the special case of the above transformation formula.

❝We humans are stability-seeking creatures. Getting accustomed to what used to seem unthinkable can feel like an accomplishment. And when the unthinkable recedes at least a bit…it’s easy to mistake it for proof that the dark times are ending.
But these comparatively small victories don’t alter the direction of our transformation — they don’t even slow it down measurably — even while they appeal to our deep need to normalize.…And so just when we most need to act — while there is indeed room for action and some momentum to the resistance — we tend to be lulled into complacency by the sense of relief on the one hand and boredom on the other.❞

Uncertainty principles for free metaplectic transformation and associated metaplectic operators
In this paper, we systematically investigate the Heisenberg-Pauli-Weyl uncertainty principle for free metaplectic transformation, as well as metaplectic operators. Specifically, we obtain two different types of the uncertainty principle for free metaplectic transformations in terms of the so-called phase derivative, one of which can be generalized to the $L^p$-case with $1\le p\le 2$. The obtained results are valid not only for free metaplectic transformations but also for general metaplectic o…

The Attractor-Cycle Notation for Finite Transformations
We describe a new notation for finite transformations. This attractor-cycle notation extends the orbit-cycle notation for permutations and builds upon existing transformation notations. How the basins of attraction of a finite transformation flow into permuted orbit cycles is visible from the notation. It gives insight into the structure of transformations and reduces the length of expressions without increasing the number of types of symbols.

Generalized Wigner-Weyl calculus for gauge theory and non-dissipative transport
We consider a theory of fermions interacting with a (in general, non-Abelian) gauge field. The theory is assumed to be essentially inhomogeneous, which might be provided by non-trivial background fields interacting with both fermions and gauge bosons. For this theory, a version of Wigner-Weyl calculus is developed, in which the Wigner transformation of the fermion Green function belongs to a matrix representation of gauge group. We demonstrate the power of the proposed formalism through the rep…

Rényi divergence guarantees for hashing with linear codes
We consider the problem of distilling uniform random bits from an unknown source with a given $p$-entropy using linear hashing. As our main result, we estimate the expected $p$-divergence from the uniform distribution over the ensemble of random linear codes for all integer $p\ge 2$. The proof relies on analyzing how additive noise, determined by a random element of the code from the ensemble, acts on the source distribution. This action leads to the transformation of the source distribution in…

Beta function without UV divergences
In this paper, we construct the beta function in the functorial formulation of two-dimensional quantum field theories (FQFT). A key feature of this approach is the absence of ultraviolet divergences. We show that, nevertheless, in the FQFT perturbation theory, the local observables of deformed theories acquire logarithmic dimension, leading to a conformal anomaly. The beta function arises in the functorial approach as an infinitesimal transformation of the partition function under the variation…

The classical theory of free analysis generalizes the noncommutative (nc) polynomials and rational functions, easily providing such results as an nc analogue of the Jacobian conjecture. However, the classical theory misses out on important functions, such as the Schur complement. This paper presents a generalization of free functions, viewing them as a natural categorial structure: functors between functor categories that commute with natural transformation.

Resonant photon scattering in the presence of external fields and its applications for the Gamma Factory
This theoretical study explores resonant elastic photon scattering in the presence of external electric and magnetic fields, motivated by potential applications in storage ring experiments, such as the Gamma Factory project at CERN. In this framework, resonant scattering involves head-on collisions of relativistic ion beams and counter-propagating laser photons, leading to a strong enhancement of the external field strength due to the Lorentz transformation between ion rest and laboratory frame…

MOND as a transformation between non-inertial reference frames via Sciama's interpretation of Mach's Principle
Milgrom's Modified Newtonian Dynamics (MOND) correction to Newtonian gravity or inertia is shown to be equivalent to a more fundamental transformation between a non-inertial local reference frame and the fixed background of the observable universe, complying with Mach's principle. Both Newton's gravitational constant and Milgrom's MOND acceleration parameter or scale constant are substituted for two varying, measurable, physical, and cosmological parameters under the justification of Sciama's i…

"But there were technologists and open source projects in attendance. Notably, representatives from the Mastodon and Bluesky teams were at the Festival. The Newsmast Foundation was also present, incisively taking part in conversations to help newsrooms onboard themselves onto both of them. I got to hang out with them all, connecting with people I’d spoken with but never interacted with in person. Mastodon has undergone a transformation, has doubled its team, and is working on smoothing out some of its rough edges, while not letting go of its core ethos. It’s also beginning to position itself as a European alternative to American social media platforms, with a community-first values system and new services to directly help organizations join the network.
Bluesky, on the other hand, has done an able job of bringing journalists onto its existing social app, and is now hard at work explaining why its underlying protocol matters. Both want to engage with newsrooms and journalists and do the right thing by them. They each have something different to prove: Mastodon that it can be usable and accessible, and Bluesky that it can provide a return to its investors and truly decentralize while holding onto its values. I’m rooting for both of them.
These platforms’ messages dovetail with my own: news can own the platforms that support them. Lots of people at the Festival were worried about the impact of US big tech on their businesses — particularly in a world where tech moguls seem to be aligning themselves with a Presidential administration that has positioned itself as being adversarial to news, journalists, sources, and, arguably, the truth. The good news is that the technology is out there, the values-aligned technologists are out there, and there’s a strong path forward. The only thing left is to follow it."
