On the Lie-solvability of Novikov algebras
Journal of Algebra and Its Applications, 2022 We prove that any Novikov algebra over a field of characteristic [Formula: see text] is Lie-solvable if and only if its commutator ideal [Formula: see text] is right nilpotent. We also construct examples of infinite-dimensional Lie-solvable Novikov algebras [Formula: see text] with non-nilpotent commutator ideal [Formula: see text].

Advanced Robotics Research, EarlyView.This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

SIMILARITY SOLUTIONS AND CONSERVATION LAWS FOR THE BEAM EQUATIONS: A COMPLETE STUDY
Acta Polytechnica, 2020 We study the similarity solutions and we determine the conservation laws of various forms of beam equations, such as Euler-Bernoulli, Rayleigh and Timoshenko-Prescott.

On saturated formations of solvable Lie algebras [PDF]
Pacific Journal of Mathematics, 1973 The concepts of formations, J^~-projectors and J^~normalizers have all been developed for solvable Lie algebras. In this note, for each saturated formation J^~ of solvable Lie algebras, the class ^Γ(κ^) of solvable Lie algebras L in which each ^"-normalizer of L is an ^'-projector is considered.

Advanced Science, EarlyView.A conversion‐resolved constitutive framework is developed for the hydrogen‐based direct reduction of iron oxide pellets. Effective reaction and transport timescales are inferred directly from measured trajectories and mapped against operating conditions, pellet architecture, and composition. The analysis reveals how late‐stage transport control emerges

International Journal of Mathematics and Mathematical Sciences, 2012 Let Cl+1(R) be the 2(l+1)×2(l+1) matrix symplectic Lie algebra over a commutative ring R with 2 invertible. Then tl+1CR = {m-1m-20-m-1T ∣ m̅1 is an l+1 upper triangular matrix, m̅2T=m̅2, over R} is the solvable subalgebra of Cl+1(R).

A SIMPLE DERIVATION OF FINITE-TEMPERATURE CFT CORRELATORS FROM THE BTZ BLACK HOLE
Acta Polytechnica, 2014 We present a simple Lie-algebraic approach to momentum-space two-point functions of two-dimensional conformal field theory at finite temperature dual to the BTZ black hole.

Advanced Science, EarlyView.Expanded‐graphite/graphene‐nanoplatelet hybrids deliver a near‐order‐of‐magnitude thermal‐conductivity enhancement in paraffin phase‐change materials. A microCT‐informed 3D modeling framework resolves the percolating EG backbone and captures sub‐voxel GNP enrichment, quantitatively linking microstructure to heat flow and revealing a graphene‐enabled ...
