Circuit equivalence in 2-nilpotent algebras
CoRR, 2019 The circuit equivalence problem of a finite algebra $\mathbf A$ is the computational problem of deciding whether two circuits over $\mathbf A$ define the same function or not. This problem not just generalises the equivalence problem for Boolean circuits, but is also of high interest in universal algebra, as it models the problems of checking ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death
FEBS Open Bio, EarlyView.Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Fractional Diffusion Equations and Equivalent Circuits Applied to Ionic Solutions
International Journal of Electrochemical Science, 2014 We investigate dilute solutions of different salts (KClO3, K2SO4, and CdCl2H2O) dissolved in Milli-Q deionized water in the context of the fractional diffusion equations and equivalent circuits.

Origins of the equivalent circuit concept: the voltage-source equivalent [PDF]
Proceedings of the IEEE, 2003 This paper describes the development of the voltage-source equivalent circuit. A subsequent paper concerns the current-source equivalent and summarizes the story. The formal roots of equivalent circuits are Ohm's Law, Kirchoff's Laws, and the Principle of Superposition.

Versatile vector tools for efficient protein screening across multiple expression systems
FEBS Open Bio, EarlyView.A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Power Conservative Equivalent Circuit for DC Networks
IEEE Access, 2020 This paper introduces a new equivalent circuit for linear direct current networks containing independent voltage sources and resistors, which represents all internal losses and can be used for the power and efficiency analysis of the actual circuit.
