Classification of Epileptic and Non-Epileptic Electroencephalogram (EEG) Signals Using Fractal Analysis and Support Vector Regression
Authors: Buchanna G. , Premchand P. , Govardhan A. 
Published: January 2022

Seizures are a common symptom of this neurological condition, which is caused by the discharge of brain nerve cells at an excessively fast rate. Chaos, nonlinearity, and other nonlinearities are common features of scalp and intracranial Electroencephalogram (EEG) data recorded in clinics. EEG signals that aren't immediately evident are challenging to categories because of their complexity. The Gradient Boost Decision Tree (GBDT) classifier was used to classify the majority of the EEG signal segments automatically. According to this study, the Hurst exponent, in combination with AFA, is an efficient way to identify epileptic signals. As with any fractal analysis approach, there are problems and factors to keep in mind, such as identifying whether or not linear scaling areas are present. These signals were classified as either epileptic or non-epileptic by using a combination of GBDT and a Support Vector Regression (SVR). The combined method's identification accuracy was 98.23%. This study sheds light on the effectiveness of AFA feature extraction and GBDT classifiers in EEG classification. The findings can be utilized to develop theoretical guidance for the clinical identification and prediction of epileptic EEG signals. Doi: 10.28991/ESJ-2022-06-01-011 Full Text: PDF
Expected Values of Molecular Descriptors in Random Polyphenyl Chains
Authors: Raza Zahid , Naz Kiran , Ahmad Sarfraz 
Published: January 2022

A chemical graph is a model used to indicate a chemical combination. In a molecular graph, vertices define atoms, and edges are represented as chemical bonds. A topological index is a single number to characterize the graph of a molecule. In this article, we study the topological properties of some special chains. The polyphenyl chains with hexagons are graphs of aromatic organic compounds. The key purpose of this article is to explore the expected value of Sombor, reduced Sombor, and average Sombor index for this category of organic compounds. It was investigated that the Sombor, reduced Sombor and average Sombor index revealed adequate discriminative potential of alkanes. It has been tested that these indicators can be used effectively in modeling chemical thermodynamic structures. The average value of the Sombor, reduced Sombor, and average Sombor index for the set of all spiro and random polyphenyl chains has been determined. Finally, the ratio between the expected values of these mentioned indices for both random chains has been resolved. Doi: 10.28991/ESJ-2022-06-01-012 Full Text: PDF

The Science of Spirit: Parapsychology, Enlightenment and Evolution by Luis Portela
Authors: Ginsberg Robert 
Published: January 2022

When one sees an opening chapter entitled “From Science to Love” it begs for further reading. After all, for most these are incongruent terms that represent two seemingly opposite sides in a debate, logic, and systematic evaluation vs. emotion. There have been many books written about the convergence of science and spirituality, and one cannot help but notice how some of today’s physicists are sounding more like spiritualists than scientists, but Dr. Portola uses this platform as wake up call for humanity.
There is a brief discussion about some well-known enlightened beings in our history, including founders of today’s organized religions, and our progression from animism to polytheism, and eventually monotheism, but Portola astutely points out the role that science played in explaining natural phenomena. Our ancestors could not have imagined these discoveries, and it was science that moved us past idol worship to spiritual independence. The author is well versed in the primary disciplines of research that suggest survival and devotes part of the book to discussions of the nature of consciousness, neuroscience, thought transmission, psychokinesis, near-death experiences, reincarnation, mediumship, and instrumental TransCommunication, but the overall message is clear that science can show us the road but changing the world paradigm starts with individual transformation. In the discussion of the neurosciences and parapsychology it is suggested that perhaps an adjustment to the scientific method is indicated by putting more value on the anecdotal personal experiences that are so prevalent. In his discussion about a paradigm shift Portola suggests that all people, including scientists and mediums, will understand more by first finding themselves through contemplation and reflection. It is only after we open to the subtle layers of consciousness that we can achieve the necessary balance needed to reach our objectives. The suggestion that scientists also need to contemplate and reflect upon the bigger picture seems contrary to the definition of science, but I suspect that Portola is correct.

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.

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.

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.
