A Generalization of Connes-Kreimer Hopf Algebra

, 2005
``Bonsai'' Hopf algebras, introduced here, are generalizations of Connes-Kreimer Hopf algebras, which are motivated by Feynman diagrams and renormalization. We show that we can find operad structure on the set of bonsais.

Fluorinated Guanidino‐Polyamine Conjugates with Ribonuclease Activity – Toward a Therapeutic Tool for Multi‐Drug Therapy

Chemistry – A European Journal, Volume 31, Issue 70, December 12, 2025.
This study presents a first‐in‐class demonstration of polymeric cationic gene delivery vectors that exhibit intrinsic artificial ribonuclease activity. Based on low‐generation PAMAM dendrimers and low molecular weight PEI polymers functionalized with a fluorinated linker containing a guanidino group, our conjugates simultaneously enable gene ...

Self‐Spiking Linear Neuromorphic Soft Pressure Sensor for Underwater Sensing Applications

Advanced Materials, Volume 37, Issue 50, December 17, 2025.
This study presents a novel design of a neuromorphic pressure sensor that can generate self‐spiking symmetric signals with direct event‐based encoding through the integration of magnetic spheres and alternating coil circuits. The key advantages of this work include high linearity up to 200 kPa (R2 = 0.997), self‐spiking behavior for simplified signal ...

Realisation of transmission zeros with two RC parallel ladders

Electronics Letters, 1967
The polynomial decompositions due to Calahan and Horowitz can be effectively used for the synthesis of passive RC parallel ladders to realise any zeros of transmission including those on the positive real axis. Only two ladders are sufficient. One of the ladders will be connected via a voltage amplifier having a gain of ±1.

Non-Hermitian description of the dynamics of inter-chain pair tunnelling

, 2017
We study inter-chain pair tunnelling dynamics based on an exact two-particle solution for a two-leg ladder. We show that the Hermitian Hamiltonian shares a common two-particle eigenstate with a corresponding non-Hermitian Hubbard Hamiltonian in which the

Scalar Decay Constant and Yukawa Coupling in Walking Gauge Theories

, 2011
We propose an approach for the calculation of the yukawa coupling through the scalar decay constant and the chiral condensate in the context of the extended technicolor (ETC). We perform the nonperturbative computation of the yukawa coupling based on the

Neutron Scattering and Its Application to Strongly Correlated Systems

, 2013
Neutron scattering is a powerful probe of strongly correlated systems. It can directly detect common phenomena such as magnetic order, and can be used to determine the coupling between magnetic moments through measurements of the spin-wave dispersions ...

QCD Factorized Drell-Yan Cross Section at Large Transverse Momentum

, 2001
We derive a new factorization formula in perturbative quantum chromodynamics for the Drell-Yan massive lepton-pair cross section as a function of the transverse momentum $Q_T$ of the pair.

Cascaded-unit-element network and its ladder- RC equivalent

Electronics Letters, 1967
This letter is aimed at establishing an equivalent LRC network for the cascaded ULC- and URC- networks. * Once the concept of equivalency is established, the wealth of classical synthesis theory of the LRC network can be inherited for the use of cascaded ULC- and URC- networks.
