    Applying the relational modelling and knowledge-based techniques to the emitter database design, Journal of Telecommunications and Information Technology, 2003, nr 1

    The appropriate emitter database is one of the most important elements in the present electronic intelligence (ELINT) system. This paper provides an overview of the relational modelling, which is used to construct the emitter database for current ELINT systems. The method described, delivers the entities’ relational diagram that is independent from the manner of the data storage in further process of implementation. This approach ensures the integrity of the measured data. The process of final emitter identification is based on “the knowledge-based approach” which was implemented during the process of constructing the database

    Applying the radiated emission to the specific emitter identification, Journal of Telecommunications and Information Technology, 2005, nr 2

    During the last years we have observed fast development of the electronic devices and electronic warfare systems (EW). One of the most principal functions of the ESM/ELINT system is gathering basic information from the entire electromagnetic spectrum and its analysis. Simultaneously, utilization of some tools of artificial intelligence (AI) during the process of emitter identification is very important too. A significant role is played by measurement and signature intelligence (MASINT) based on non-intentional emission (calls-radiated emission). This emission is a source of knowledge about an analysed emitter due to its incidental “chemical”, “spectral” traces and non-communication emitter’s characteristics. The process of specific emitter identification (SEI) based on extraction of distinctive radiated emission features is presented by the authors. Specially important is utilization of a database (DB) in the process of identifying a detectable radar emission

    Background: The evidence base regarding the safety of intravenous (IV) iron therapy in patients with chronic kidney disease (CKD) is incomplete and largely based on small studies of relatively short duration. Methods: FIND-CKD (ClinicalTrials.gov number NCT00994318) was a 1-year, open-label, multicenter, prospective study of patients with nondialysis-dependent CKD, anemia and iron deficiency randomized (1:1:2) to IV ferric carboxymaltose (FCM), targeting higher (400-600 µg/L) or lower (100-200 µg/L) ferritin, or oral iron. A post hoc analysis of adverse event rates per 100 patient-years was performed to assess the safety of FCM versus oral iron over an extended period. Results: The safety population included 616 patients. The incidence of one or more adverse events was 91.0, 100.0 and 105.0 per 100 patient-years in the high ferritin FCM, low ferritin FCM and oral iron groups, respectively. The incidence of adverse events with a suspected relation to study drug was 15.9, 17.8 and 36.7 per 100 patient-years in the three groups; for serious adverse events, the incidence was 28.2, 27.9 and 24.3 per 100 patient-years. The incidence of cardiac disorders and infections was similar between groups. At least one ferritin level ≥800 µg/L occurred in 26.6% of high ferritin FCM patients, with no associated increase in adverse events. No patient with ferritin ≥800 µg/L discontinued the study drug due to adverse events. Estimated glomerular filtration rate remained the stable in all groups. Conclusions: These results further support the conclusion that correction of iron deficiency anemia with IV FCM is safe in patients with nondialysis-dependent CKD

    W. Sedlak's Idea of the Chemical-Electronic Coupling in Organisms

    No full text
    The critical discussion on the possible existence of the coupling between biochemical reactions and electronic processes in biological solids is undertaken in connection with the concept of bioplasma and the electromagnetic theory of life. Firstly, a review of more important denotations of the term "coupling" in various disciplines: cybernetics, physics, genetics, biochemistry, thermodynamics, etc. is made. Secondly, a review of related terms with the same designation: quantum seam of life, quantum generator of physical plasma, quantum of life, the least unit of life, quantum pacemaker, quantum junction of life, biological quantum amplifier, etc. has been given. Thirdly, properties, origins, and functions of the chemical-electronic coupling have been discussed. New terms as "photonic microprocessor" and "optoelectronic microrobot" have also been proposed

    The Hypotheses of Silicon Biogenesis and the Problem of the Elementary Unit of Life. Part I: Sedlak’s Hypothesis of “Siliceous Life Forms” and Cairns-Smith’s Hypothesis of “Mineral Genes”

    W artykule przedstawiono problem modelowania minimalnego systemu żywego z punktu widzenia hipotez mineralnych początków życia. Szczególną uwagę poświęcono hipotezom sformułowanym przez Włodzimierza Sedlaka (krzemowe formy życia) i przez Alexandra Grahama Cairns-Smitha (mineralny „gen”). Wskazano na możliwość rekonstrukcji nowego modelu elementarnej jednostki życia. Dokonano przeglądu piśmiennictwa dotyczącego tej problematyki.The problem of the modeling of a minimal living system is presented from the viewpoint of the hypotheses of mineral origins of life. Special attention is paid to the hypotheses formulated by Włodzimierz Sedlak (siliceous life forms) and by Alexander Graham Cairns-Smith (the mineral “gene”). The possibility of the reconstruction of a new model of elementary unit of life is suggested. The significant works concerning above problems have been reviewed

    Włodzimierz Sedlak’s Contribution to the Study of the Origin of Life: From Biochemistry of Silicon across Bioelectronics to Theology of Light

    No full text
    The subject of the presentation was to reveal the main components of the views of Rev. Włodzimierz Sedlak (31.10.1911–17.02.1993) concerning the origin of life. The development of these views passed through the following stages: 1) the theory of silicic life forms (1959–1967) which he labeled “the theory of siliconides”, 2) the bioelectronic model of abiogenesis (1967–1988), and 3) speculations about electromagnetic biogenesis. The basic claims of the theory of silicic life forms are the following: (a) silicon is an essential component of biosystems and fulfils significant roles in phylogenetically older forms of life; (b) the previous essential role of silicon in the organization of life has been reduced in higher organisms to the role of a microelement; (c) the attempts at the reconstruction of the chemical evolution of life should be undertaken, to extend it beyond the organic compounds of carbon, namely to those containing silicon and forming the most primitive forms of life on the Earth; (d) hypothetic silicic organisms made up the most primitive life on the Earth.. The main theses of bioelectronic model of abiogenesis are the following: (a) there exists the coupling between chemical reactions and electronic processes in organisms (he calls it “the quantum seam of life”); photons act as a coupling factor between these two classes of processes; (b) the existence the such coupling makes the generation and duration of the plasma state of particles possible in all metabolizing parts of the organism; (c) there exists bioplasma – a new state of matter – that is characteristic for living organisms only; (d) the first act of the creation of the chemical-electronic coupling is to be regarded as equivalent with biogenesis: (e) bioplasma existed well before the macroscopic organic morphological structures were formed and functioned already when the life was based on aluminosilicates. Sedlak’s speculation on the electromagnetic biogenesis implies that the evolution of biosphere began with the moment of birth of light, i.e. in one of the earliest phases of existence of Universe. God, identified by him with the Light, created life, possessing the luminous nature. Life never altered its electromagnetic foundation: either at any new stage, or at a new level of organization, or when the first human being was created. It seems that Sedlak’s works can be valuable for the present and future investigations aimed at the reconstruction of biogenesis. Although they are undervalued now, they should be regarded as containing many valuable intuitions. They deserve a thorough analysis and – where it is possible – empirical testing of implications drawn from them
