Errors and Their Mitigation at the Kirchhoff-Law-Johnson-Noise Secure Key Exchange
Yessica Saez, Laszlo B. Kish
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0081103
Abstract: A method to quantify the error probability at the Kirchhoff-law-Johnson-noise (KLJN) secure key exchange is introduced. The types of errors due to statistical inaccuracies in noise voltage measurements are classified and the error probability is calculated. The most interesting finding is that the error probability decays exponentially with the duration of the time window of single bit exchange. The results indicate that it is feasible to have so small error probabilities of the exchanged bits that error correction algorithms are not required. The results are demonstrated with practical considerations.
Cable Capacitance Attack against the KLJN Secure Key Exchange

Physics , 2015, DOI: 10.3390/info6040719
Abstract: The security of the Kirchhoff-law-Johnson-(like)-noise (KLJN) key exchange system is based on the Fluctuation-Dissipation-Theorem of classical statistical physics. Similarly to quantum key distribution, in practical situations, due to the non-idealities of the building elements, there is a small information leak, which can be mitigated by privacy amplification or other techniques so that the unconditional (information theoretic) security is preserved. In this paper, the industrial cable and circuit simulator LTSPICE is used to validate the information leak due to one of the non-idealities in KLJN, the parasitic (cable) capacitance. Simulation results show that privacy amplification and/or capacitor killer (capacitance compensation) arrangements can effectively eliminate the leak.
Current and voltage based bit errors and their combined mitigation for the Kirchhoff-law-Johnson-noise secure key exchange
Yessica Saez,Laszlo B. Kish,Robert Mingesz,Zoltan Gingl,Claes G. Granqvist
Computer Science , 2013, DOI: 10.1007/s10825-013-0515-2
Abstract: We classify and analyze bit errors in the current measurement mode of the Kirchhoff-law-Johnson-noise (KLJN) key distribution. The error probability decays exponentially with increasing bit exchange period and fixed bandwidth, which is similar to the error probability decay in the voltage measurement mode. We also analyze the combination of voltage and current modes for error removal. In this combination method, the error probability is still an exponential function that decays with the duration of the bit exchange period, but it has superior fidelity to the former schemes.

Everolimus-eluting coronary stents
Alejandro Saez, Raul Moreno
Medical Devices: Evidence and Research , 2010, DOI: http://dx.doi.org/10.2147/MDER.S4422
Abstract: olimus-eluting coronary stents Review (4155) Total Article Views Authors: Alejandro Saez, Raul Moreno Published Date September 2010 Volume 2010:3 Pages 51 - 56 DOI: http://dx.doi.org/10.2147/MDER.S4422 Alejandro Saez, Raul Moreno Division of Interventional Cardiology, University Hospital La Paz, Madrid, Spain Abstract: Bare metal stents enabled a reduction in the risk of early procedural complications and restenosis in comparison with balloon angioplasty alone, but introduced a new and device-specific iatrogenic condition, ie, in-stent restenosis due to increased neointimal hyperplasia. Sirolimus- and paclitaxel-eluting stents reduce restenosis and the need for new revascularizations in comparison with bare metal stents, although at the cost of a slight increase in the risk of late stent thrombosis and a need for prolonged dual antiplatelet therapy. Everolimus is an analog of sirolimus with an increased solubility. In this review, the currently available evidence for everolimus-eluting stents is revised, including randomized trials against bare metal stents, and head-to-head trials comparing this stent with other drug-eluting stents.

Los Sistemas de Costes Convencionales y el Método ABC: Análisis Comparativo
Angel Saez Torrecilla
Revista de Contabilidad : Spanish Accounting Review , 1997,
Abstract: A fin de proporcionar una mejor respuesta a los nuevos problemas a que se enfrentan sus usuarios, el carácter dinámico de la Contabilidad de Gestión se pone de manifiesto en el desarrollo de nuevas técnicas de gestión más acordes con la evolución del entorno productivo y empresarial. En este sentido, una de las principales técnicas de gestión desarrollada en la última década ha sido el modelo ARC. En el presente trabajo se realiza un análisis comparativo entre el modelo tradicional de costes completos y el ARC a través del estudio de las distintas etapas del proceso de cálculo y asignación de costes seguidas en este último modelo. In order to provide a better answer to the new problems that their users must face, the dynamic character of Management Accounting is highlighted in the development of new management techniques more suited to the evolution of a productive and managerial environment. In this sense, one of the major management accounting techniques developed over the last decade has been the ARC model. In this paper we carry out a comparative analysis between the traditional full-costing model and the ARC through the study of the different stages of cost calculation and allocation process in the latter model.
