Minding the Matter of Psychokinesis: A Review of Proof- and Process-Oriented Experimental Findings Related to Mental Influence on Random Number Generators
Authors: Williams Bryan J
Published: January 2022

Many experiments have been conducted over the past eight decades to explore whether the ostensible psychic ability of psychokinesis (PK, or "mind over matter") might be a genuine human potential, and the most extensive of these have involved attempts to mentally influence the output of electronic, binary-bit random number generators (RNGs). Research of this type can generally be divided into two lines: proof-oriented (concerned with the accumulation and statistical evaluation of data from controlled experiments designed specifically to test for the presence of PK effects on the microscopic scale) and process-oriented (concerned with conducting exploratory experiments designed to systematically vary certain test conditions in order to search for and identify any physical, biological, and psychological factors which might have a role in improving or moderating PK effects). To help orient novice investigators and cross-disciplinary researchers who may be considering work along these lines (as well as offer some initial guiding insight on possible directions for future research), this paper provides a general review of some of the notable proof- and process-oriented findings that have been obtained to date in experimental microscopic PK research using RNGs. The review generally indicates that although a considerable amount of proof-oriented data for micro-PK has accumulated over the years, the relatively sparse amount of process-oriented data available at present leaves a lot of open questions regarding the underlying factors involved, providing ample opportunity for novice investigators and cross-disciplinary researchers to make valuable research contributions in the future.

Published: January 2022

BACKGROUND: Treatment of infective endocarditis secondary to Pseudomonas aeruginosa can be challenging because of this organism’s ability to acquire antimicrobial resistance over time. METHODS: We describe a patient with native aortic valve infective endocarditis due to P. aeruginosa who developed progressive multi-drug resistance while on therapy. The resistance mechanisms were characterized using whole-genome sequencing. RESULTS: We identified two mutations in subsequent isolates ( dacB and OprD) that conferred resistance to anti-pseudomonal penicillins, cephalosporins, and carbapenems. The patient was treated with combination high-dose continuous infusion meropenem and ciprofloxacin therapy, in addition to bioprosthetic aortic valve replacement and repair of ventricular septal wall defect. Antibiotics were continued for 6 weeks post–cardiac surgery and the patient remains infection free 18 months post-completion of antibiotic therapy. CONCLUSION: Clinicians should be aware of the ability of P. aeruginosa to acquire resistance mechanisms in response to selective antibiotic pressures in high-inoculum infections such as infective endocarditis. The mutations identified in this case report correlated well with the evolving antimicrobial resistance profile observed.

The article highlights the authors' view on the peculiarities of providing surgical care in the system of medical support of the Defense Forces of Ukraine and identifies problems that need to be addressed at the organizational level. The existence of the armed conflict in eastern Ukraine, which has been going on since 2014, and the experience of the medical service gained over the years, encourages the creation of new structures that bring medical care closer to the wounded. This, in turn, allows you to keep the rule of the "golden hour", because the lack of medical care for 1 hour increases mortality by 10-15 %. The purpose of the work is to develop new structures of the medical forces of the Armed Forces of Ukraine to improve the efficiency of medical care at the second level of medical care. Tactical-special training was conducted, which worked out the main issues of deployment and operation of the advanced surgical team, as a separate stage of medical care. During the practical part, the scope of medical care was analyzed and standardized depending on the operational situation. The issues of terminology are considered in the work, definitions of separate terms are given and their semantic loading is specified. The authors considered the structure and organization of the work of advanced surgical support groups, qualitative characteristics of medical care at the stages of medical evacuation of the second level of medical care, its scope and content, options for strengthening medical care. Variants of application of advanced surgical groups in the conditions of the armed conflict of low intensity and local war – the conflict of high intensity are covered. The obtained results indicate that the creation of an advanced surgical team allows to bring medical care closer to the line of combat. The mobility of the group provides the opportunity to be directly near the center of sanitary losses.
Evaluation of changes in instrumental and biochemical markers of heart diseases in patients with bladder cancer under the condition of intravenous and intravesical doxorubicin administration
Authors: Hodovan N. L.
Published: January 2022

Due to the constant increase in morbidity and mortality, bladder cancer remains a pressing problem in modern medicine. Despite the success of chemotherapy, chemotherapy physicians around the world have been concerned about the safety of these drugs for many years. Doxorubicin has been used as an antitumor drug for more than 40 years in various hematological and solid malignancies, however, its toxic effects when administered intravenously to vital organs and organ systems, including the heart, require further research. The aim of our study was to evaluate the manifestations and progression of cardiotoxicity in patients with bladder cancer with systemic and intravesical administration of doxorubicin. The study included 96 patients who were divided into three groups: the first group or the control group – patients who had a confirmed diagnosis of first stage bladder cancer, were treated surgically and did not receive doxorubicin; the second group – patients who, in addition to surgical treatment, received doxorubicin systemically (intravenously) in a therapeutic dose; the third group – patients who received doxorubicin at a dose of 50 mg, locally, by instillation of the drug into the bladder cavity, after prior catheterization with an elastic catheter. ECG data and biochemical markers of myocardial destruction before and after chemotherapy were studied. The study found that systemic serial administration of doxorubicin to patients with bladder cancer causes significant changes in the myocardium after the first course of chemotherapy. A single intravesical instillation of doxorubicin does not cause changes in laboratory and instrumental heart rate.

Psychological rehabilitation of combatants is especially relevant today, when the hybrid war in the east of our country has been going on for eight years. The scale of this phenomenon in Ukrainian society requires an active study of the psychological problems of servicemen that have emerged during this time. The aim of the work is to determine the effectiveness of medical rehabilitation of servicemen after being in the combat zone according to the indicators of emotional burnout. A specially designed questionnaire was used to assess the impressions of combat and domestic problems that arise in the military in the area of the Joint Forces Operation (JFO) in relation to the effects of internal and external factors of combatants. To determine the development of chronic fatigue, the method "Diagnosis of emotional burnout" by Boyko V. V. was used. Statistical analysis of the obtained results was carried out with the involvement of methods of parametric and nonparametric statistics, cluster, stepwise multiple correlation and stepwise discriminant analysis using the software package STATISTICA 13.3. Analysis of the obtained data showed that six psychophysiological qualities (Rsl=0.67) were the most related to the parameter of stress load "before" treatment. The list of informative characteristics indicates the high activity of the body of servicemen, the dependence of endurance of their nervous system, the level of concentration and reliability of activity from the received stress. After treatment, the number of informative psychophysiological indicators decreases significantly, and the strength of the connection with stress increases slightly (Rsl=0.78), which indicates the gradual restoration of relevant body functions. It was found that the characteristics of emotions are associated with stress (Rsl=0.52). Before treating these relationships, there are three feelings: "self-dissatisfaction", "caged", "emotional and moral disorientation". After treatment, this connection is slightly reduced along with the elimination of the emotion of "self-dissatisfaction", which characterizes the gradual ordering, systematization of the feelings of the combatant, starting with the relationship to himself. It was found that the average efficiency of 10-day treatment is 16.7 %, which indicates the benefit of restorative procedures. Information technology has been developed that allows to quantify the outcome of treatment, the use of which will allow a meaningful approach to the treatment process, to carry out dynamic control of its results and improve rehabilitation techniques.

Research firm Gartner defines IoT as a network of physical objects that contain the means to interact with the environment and with each other, as well as to transmit information about their status and receive commands. McKinsey offers a less abstract definition: IoTs are sensors and drives built into physical devices and Internet connections over wired or wireless networks. IoT is developed not only by device manufacturers, but also by specialized organizations, including the International Telecommunication Union (ITU), the Industrial Internet Consortium and the IETF. In the recommendations of Y.2060 of the International Telecommunication Union, called the Overview of the Internet of Things, the Internet of Things appears as «a global infrastructure that provides complex services by connecting physical and virtual things based on existing and evolving, functionally compatible information and communication technologies». A thing in this definition means an object of the physical or virtual world that can be identified and connected to communication networks. A device in the context of IoT is an element of equipment that has the required communication capabilities and can perform measurements, operate under certain conditions, enter, store and process data. As is typical of any new concept, the process of standardizing the Internet of Things has gone from understanding the network architecture, requirements and capabilities of «things» and ways to apply them to specific technologies that allow to organize the Internet of Things direct interaction of «things» with each other and with devices and people from the outside environment. The article considers the peculiarities of the main organizations involved in IoT standardization at the global level, identifies technological, economic and social benefits of ISO standards, offers a variant of building a topology for the study of IoT protocols, which corresponds to the architecture of the Internet of Things.

The article discusses the topical issue of determining the effectiveness of the use of social networks. Now we live in the age of information technology, where no modern person can do without social networks. They are the most popular resource on the Internet and have become an integral part of our lives. The social network contains a tremendous potential in organizing the collective work of distributed groups of society. The main factor behind the popularity of social networks is the creation of simple interactions between people through social networks. Social networks provide information about the current situation, about the actions of the authorities, about natural phenomena. Information is transmitted in various formats that are convenient for perception: in the form of text messages, in the form of photos, audio, video. The article provides a statement of the problem: Social networks today are one of the most visited resources on the Internet. Therefore, the problem arises of finding methods to improve the effectiveness of the use of social networks in various spheres of society. Against the background of solving this problem, it becomes necessary to determine the effectiveness of the use of social networks for any needs of society, for which it is necessary to have a toolkit for assessing various processes in social networks. The traditional solution to this problem is rooted in the plane of the application of various indicators, parameters and characteristics of assessing the processes and states of social networks, which are not combined into a system of indicators for assessing their effectiveness. The creation of such a system is possible on the basis of an analysis of the architecture of building social networks and the functional purpose of its components, analysis of the specifics and characteristics of processes and methods of using social networks by representatives of society. It is believed that making certain conclusions about the processes taking place in social networks, predicting the behavior of its participants, and simulating social interaction of social networks between representatives of society is possible only after analyzing the information that exists in social networks. It is shown that in order to use mathematical models and various methods for analyzing the properties and data of social networks, a system of indicators of the effectiveness of the functioning of social networks is required. The proposed system of indicators of the effectiveness of the functioning of social networks, which allows you to reveal the features of the use of various forms of relationships between representatives of society in any social processes.

At the present stage of development of society, one of the most important areas is information technology. Every year the amount of information is constantly increasing, forcing you to spend more and more time and labor on your processing. In this regard, modern automated information systems are becoming more and more necessary, able to process input information in a short time and provide it in a convenient form that allow rational and accessible storage of used information. The introduction of information technology has also begun to be used in medical institutions. To do this, you need to move to a more modern level of computer technology. It is computer technology that helps to increase the speed of personnel management and the preparation of paper documentation. Establishment of an expert-diagnostic system, the main task of which is to obtain information based on the list of symptoms of the patient, and to establish the most probable disease that corresponds to the patient's state of health. The objectives of the development are: to remove the factor of human error in diagnosis, increase the percentage of correctly diagnosed, facilitate the process of diagnosis by symptoms, increase patients' trust in doctors, increase the speed of diagnosing patients. The created system has all the capabilities necessary for efficient and fast management of ambulance workers. It contains all the basic tools you may need to function properly, generate reports for the required period, register new employees (users), set up an individual work schedule and receive patients, manage received calls, administer and control vehicles. The WEB interface of the «Reception Manager» was created for the application software interface to be able to coordinate and direct free machines to the specified calls. During the theoretical analysis, the general structure of the system was presented, which includes an application programming interface (API) with web-interfaces, which is divided into several main roles: the role of «Reception Manager», the role of «Direction Manager», the role of «Patient». The system will significantly speed up the work of ambulances by taking over almost all the work on communication between employees and document management, as well as patient management. Collectively, the developed systems will be able to significantly increase the speed and efficiency of doctors.

OBJECTIVE

Prognostication of glioblastoma survival has become more refined due to the molecular reclassification of these tumors into isocitrate dehydrogenase (IDH) wild-type and IDH mutant. Since this molecular stratification, however, robust clinical prediction models relevant to the entire IDH wild-type glioblastoma patient population are lacking. This study aimed to provide an updated model that predicts individual survival prognosis in patients with IDH wild-type glioblastoma.

METHODS

Databases from Germany and the Netherlands provided data on 1036 newly diagnosed glioblastoma patients treated between 2012 and 2018. A clinical prediction model for all-cause mortality was developed with Cox proportional hazards regression. This model included recent glioblastoma-associated molecular markers in addition to well-known classic prognostic variables, which were updated and refined with additional categories. Model performance was evaluated according to calibration (using calibration plots and calibration slope) and discrimination (using a C-statistic) in a cross-validation procedure by country to assess external validity.

RESULTS

The German and Dutch patient cohorts consisted of 710 and 326 patients, respectively, of whom 511 (72%) and 308 (95%) had died. Three models were developed, each with increasing complexity. The final model considering age, sex, preoperative Karnofsky Performance Status, extent of resection, O6-methylguanine DNA methyltransferase (MGMT) promoter methylation status, and adjuvant therapeutic regimen showed an optimism-corrected C-statistic of 0.73 (95% confidence interval 0.71–0.75). Cross-validation between the national cohorts yielded comparable results.

CONCLUSIONS

This prediction model reliably predicts individual survival prognosis in patients with newly diagnosed IDH wild-type glioblastoma, although additional validation, especially for long-term survival, may be desired. The nomogram and web application of this model may support shared decision-making if used properly.

The article is devoted to the study of the influence of carbon content in the auger material on its wear during dehydration of municipal solid waste in the garbage truck. Using the method of regression analysis, the hyperbolic regularities of screw wear depending on the carbon content in its material for different values of the friction path were determined. Graphical dependences of auger wear were constructed, depending on the carbon content in its material for different values of the friction path, which confirms the sufficient convergence of the obtained patterns. Carrying out additional regression analysis allowed to obtain the pattern of wear of the auger, depending on the carbon content in its material and the friction path, which established the following. After two weeks of operation and wear of the auger during the dewatering of solid waste in the garbage truck, increasing the carbon content in the auger material from 0.2% to 2.1% leads to a decrease in the energy intensity of dehydration of solid waste from 19.6% to 4.4 %, which makes the process of dehydration in the garbage truck cheaper. The graphical dependence of the reduction of energy consumption of dehydration of solid household waste due to increased carbon content in the auger material during its two-week wear is presented. The practicality of further research is to determine the rational material of the auger and ways to increase its wear resistance

The relationship between the elastic modulus and the porosity of powder coatings has been investigated for different methods of their deposition. Porosity is the main means of assessing the quality of coatings and depends on the techniques for their production. A decrease in the elastic modulus of coatings after gas flame spraying is due to the presence of porosity to 30%, and after electric arc spraying – to 20%. The electric contact method of forming coatings makes it possible to reduce porosity to 5-6% and so to bring the value of the elastic modulus of coatings closer to that of compact materials

Based on a combination of a system-oriented approach and a synergetic concept, the requirements for the design of tribological polymer composite materials with high-modulus fillers are formed. These materials are considered as an open dynamic system that evolves during operation. The principles of the synergetic concept for tribotechnical systems taking into account the theory of evolution and self-organization to ensure its self-governing and self-supporting development are considered. It is revealed that in the process of interaction of elements of the tribosystem the cooperation of local areas of their materials is formed with the emergence of a critical number of such areas and the creation of an information field about their functioning. The direction of self-organization of processes and states of parts materials in the tribotechnical system and expediency of using the conclusions of the synergetic concept in the construction of polymer composite materials, as well as their nonequilibrium are shown. The issues of creation of tribophysical bases of wear resistance of tribotechnical systems with conjugations of the details made or strengthened by polymeric composite materials are considered. Polymer composite materials are considered as a set of interacting ensembles of local areas, the principle of maximum wear resistance (reliability) is used. Tribological principles and requirements to creation and substantiation of expediency and efficiency of use of high-modulus fillers in polymers are formulated
