However, this concept is still not really understood, when it is referred for instance to consciousness and its informational structure. In this paper it is followed the concept of information from philosophical to physics perspective, showing especially how this concept could be extended to matter in general and to the living in particular, as a result of the intimate interaction between matter and information, the human body appearing as a bipolar informed-matter structure. It is detailed on this way how this concept could be referred to consciousness, and an informational modeling of consciousness as an informational system of the human body is presented. Based on the anatomic architecture of the organism and on the inference of the specific information concepts, it is shown that the informational system of the human body could be described by seven informational subsystems, which are reflected in consciousness as corresponding cognitive centers. These results are able to explain the main properties of consciousness, both the cognitive and extra-cognitive properties of the mind, like that observed during the near-death experiences and other similar phenomena. Moreover, the results of such a modeling are compared with the existing empirical concepts and models on the energetic architecture of the organism, showing their relevance for the understanding of consciousness.展开更多

Based on recent discoveries of quantum physics and astrophysics, revealing a new understanding of our environment and starting from some philosophical concepts on information of matter and of living structures, this work discusses the dynamics of information within the frame of the Informational Model of Consciousness as an informational system of the human body, connected both to the environment and to the body itself, to control the adaptation for survival. It is shown that consciousness is actually an informational projection in the mind of seven informational subsystems, three of which forming the operative system of consciousness for the short-term adaptation, and other three forming the programmed operating system, dedicated to the maintenance of body and to the long-term survival of species, showing various inputs and outputs of information. The seventh subsystem is the information pole, connecting the organism with the external information, especially related to the extra-sensorial properties of the mind, the human body appearing as a bipolar info-matter structure, managed by the brain. The received information is progressively integrated into the informational system of the organism, which absorbs and emanates information as a reactive system for adaptation, able to operate both with matter-related (codified) and non-matter related (virtual) information. As both connections with external and internal environment (body itself) can be described in terms of information, this model opens the gate to investigate consciousness by means of the tools of the information science, offering also answers to the philosophic “mind-body” problem and to the “hard” problem and showing correspondences with some ancient philosophies.展开更多

Since genetic material is life’s blueprint, better understanding of the origins of life is predicated on deciphering the conditions that allowed the formation of this complex molecule with its unique properties. In this article, we propose and examine the hypothesis that informational entropy models would allow for the formation of complex organic molecules with genetic properties, without the disruption of the second law of thermodynamics. Therefore, we demonstrate that formation of life’s blueprint may have initially been derived by informational entropy by means of decomplexification of the materials with higher informational entropy content, leading to the formation of primitive genetic molecules.展开更多

Methodology: A prospective, qualitative study with a phenomenological approach was carried out at the Brachytherapy unit of the National Institute of Oncology in Rabat, Morocco. Purposive sampling was used to recruit 31 patients undergoing high dose-rate brachytherapy for cervical cancer from July 2020 to August 2020. Semi-structured, one-to-one interviews were conducted by a female radiation oncologist in Arabic, guided by a theme list. The interviews were translated and a thematic analysis was performed. Results: Data saturation was achieved having interviewing 31 participants, aged 27 - 70 years. Findings on patients’ informational needs were the overarching theme and form the focus of this article. The informational needs included: providing patients with disease- and treatment-related information in their home language;adequate information concerning pre-treatment preparation, possible side-effects, and sexual intercourse;and providing patients with informative material adapted to their needs as standard procedure. Conclusion: This study has identified unmet women’s informational needs during brachytherapy for cervical cancer. Providing patients with sufficient and understandable information, adequate preparation before the procedure, more sensitive support during the procedure, and debriefing afterward could lessen feelings of fear and anxiety towards treatment delivery. Guidelines with a patient-centered approach could thus be developed to be used as a tool to assist members of multidisciplinary teams in providing quality care to this group of women.展开更多

It is shown that informational noise's entropy as opposed to used differential entropy of continuous signals defines the quantity of qualitative information related to the features of element's structure. Proposed quantitative assessment of information can be used for calculation of information contained in the own noises of other technical systems.展开更多

The author comes to a conclusion that the up-to-date level of the development of information technologies in Sub-Saharan countries doesn't give us an opportunity to estimate the close equal integration of the region into the global information and communication space. African countries don't have appropriate financial and technological resources which seem to be necessary when creating the well-developed information and telecommunication infrastructure on their territory. The author argues that in order to reach the level of the development of well-developed nations African states are forced to seek the aid of Western countries which use the technological and financial dependence of their African partners as the strong instrument of preservation of their influence in the region. In current circumstances it would be very difficult for Afxican countries to create a self-reliant information society and to preserve their cultural identity in the upcoming information age.展开更多

However, concerns have arisen regarding the accuracy, validity, and reproducibility of reported findings. Issues such as replication problems, fraudulent practices, and a lack of expertise in measurement theory and uncertainty analysis have raised doubts about the reliability and credibility of scientific research. Rigorous assessment practices in certain fields highlight the importance of identifying potential errors and understanding the relationship between technical parameters and research outcomes. To address these concerns, a universally applicable criterion called comparative certainty is urgently needed. This criterion, grounded in an analysis of the modeling process and information transmission, accumulation, and transformation in both theoretical and applied research, aims to evaluate the acceptable deviation between a model and the observed phenomenon. It provides a theoretically grounded framework applicable to all scientific disciplines adhering to the International System of Units (SI). Objective evaluations based on this criterion can enhance the reproducibility and reliability of scientific investigations, instilling greater confidence in published findings. Establishing this criterion would be a significant stride towards ensuring the robustness and credibility of scientific research across disciplines.展开更多

Introduction: Patients who are well informed before undergoing surgery experience reduced stress and increased understanding of the postoperative process. Although providing patients with written information before gynecological surgery is widely used and assumed important, no study has investigated what information patients truly need. Methods: In 2014, all 59 gynecological departments in Sweden were asked to provide the information letter they send to patients before hysterectomy on benign indication. 32 letters were analyzed using frequency analysis. In addition, three focus groups were conducted and these data were submitted to Qualitative Content Analysis. Results: The analysis of the information letters showed great variation and discrepancy in pre-operative information. The analysis of the focus groups resulted in the theme You can’t see the forest for the trees, reflecting that, the women found it very difficult to identify the most important information among the massive amount information received. Conclusions: The informational letters did not meet the patients’ expectations and needs. Practice implications: This study could serve as a foundation for the content of informational letters.展开更多

This study was aimed to make a computational model considering the mechanism of informational masking. Several psy- choacoustic experiments were conducted to test the ef- fect of informational masking on speech intelligibility by manipulating the number of masking talker, speech rate, and the similarity of F0 contour between target and masker. The results showed that the speech recep- tion threshold for the target increased as the F0 contours of the masker became more similar to that of the tar- get, suggesting that the difficulty in segregating the tar- get harmonics from the masker harmonics may underlie the informational masking effect. Based on these stud- ies, a new auditory computational model was made by inducing the auditory function of harmonic extraction to the traditional model of speech intelligibility index (SII), named as harmonic extraction (HF) model. The predictions of the HF model are highly consistent with the experimental results.展开更多

Based on these stud- ies, a new auditory computational model was made by inducing the auditory function of harmonic extraction to the traditional model of speech intelligibility index (SII), named as harmonic extraction (HF) model. The predictions of the HF model are highly consistent with the experimental results.
