Universal Uncertainty Principle in the Measurement Operator Formalism
, 2005 Heisenberg's uncertainty principle has been understood to set a limitation on measurements; however, the long-standing mathematical formulation established by Heisenberg, Kennard, and Robertson does not allow such an interpretation.

Active disturbance rejection control of temperature of thermoelectric module
Revista Iberoamericana de Automática e Informática Industrial RIAI, 2021 This article presents an active disturbance rejection approach for the control of the temperature in the cold face of a thermoelectric module fed by a type buck DC-DC converter. The dynamics of the module is seen as a disturbance of an unknown nature and

Estimates for practical quantum cryptography [PDF]
, 1999 In this article I present a protocol for quantum cryptography which is secure against attacks on individual signals. It is based on the Bennett-Brassard protocol of 1984 (BB84). The security proof is complete as far as the use of single photons as signal

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
