Optimizing 3D Bin Packing of Heterogeneous Objects Using Continuous Transformations in SE(3)
Advanced Intelligent Systems, EarlyView.This article presents a method for solving the three‐dimensional bin packing problem for heterogeneous objects using continuous rigid‐body transformations in SE(3). A heuristic optimization framework combines signed‐distance functions, neural network approximations, point‐cloud bin modeling, and physics simulation to ensure feasibility and stability ...

On Propagation in Loop Quantum Gravity
Universe, 2022 A rigorous implementation of the Wheeler–Dewitt equations was derived in the context of Loop Quantum Gravity (LQG) and was coined Quantum Spin Dynamics (QSD). The Hamiltonian constraint of QSD was criticised as being too local and to prevent “propagation”

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model
Systems Research and Behavioral Science, EarlyView.ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Micro-canonical and canonical description for generalised entropy
Physics Letters B, 2023 Few parameters dependent generalised entropy includes Tsallis entropy, Rényi entropy, Sharma-Mittal entropy, Barrow entropy, Kaniadakis entropy, etc as particular representatives. Its relation to physical systems is not always clear.

Insights into the catalytic mechanism of formate dehydrogenases from different microbial sources
The FEBS Journal, EarlyView.This integrated study combines experimental enzyme kinetics with QM/MM simulations to map the catalytic mechanisms of four formate dehydrogenases at the atomic level. This approach reveals the key determinants of catalytic efficiency and guides the rational design of biocatalysts for effective CO2 reduction—a crucial step towards sustainable ...

Generalised Wick Transform in Dimensionally Reduced Gravity
, 2003 In the context of canonical quantum gravity, we study an alternative real quantisation scheme, which is arising by relating simpler Riemannian quantum theory to the more complicated physical Lorentzian theory - the generalised Wick transform.

Making the gravitational path integral more Lorentzian, or: Life beyond Liouville gravity [PDF]
, 1999 In two space-time dimensions, there is a theory of Lorentzian quantum gravity which can be defined by a rigorous, non-perturbative path integral and is inequivalent to the well-known theory of (Euclidean) quantum Liouville gravity.
