Background To evaluate incidence and search for possible predictors of brain fog and quality of life at work (QoL-W) among low-to-moderate risk subjects previously hospitalized due to COVID-19. Material and Methods Participants aged ≥18 retrospectively reported 8 brain fog symptoms pre-COVID-19, at 0–4, 4–12 and >12 weeks post-infection via validated clinical questionnaire. The QoL-W was assessed with a 4-point Likert scale where 0, 1, 2, and 3 meant no, mild, moderate, and severe impairment in performing activities at work, respectively. Data on age, sex, comorbidities, and laboratory results (including first in-hospital high-sensitivity cardiac troponin I [hs-cTnI] measurement) were gathered. Results The study included 181 hospitalized subjects (age Me = 57 years), 37.02% women. Most had low disease severity (Modified Early Warning Score = 1, 77.90%) and low comorbidity (Charlson Comorbidity Index 0: 28.72%, 1–2: 34.09%), with no intensive care unit treatment needed. COVID-19 led to almost 3-fold increased brain fog symptoms, with incidence of 58.56%, 53.59%, and 49.17% within 4, 4–12, and >12 weeks, respectively (p < 0.001). First in-hospital hs-cTnI levels were 47.3% higher in participants who later presented with brain fog at median follow-up of 26.7 weeks since the diagnosis of the SARS-CoV-2 infection. Individuals who experienced at least one brain fog symptom at follow-up, had elevated hs-cTnI, less often presented with atrial fibrillation, and used anticoagulants during initial hospitalization due to COVID-19. The Hs-cTnI >11.90 ng/l predicted brain fog symptoms in multivariable model. COVID-19 was associated with 3.6‑fold, 3.0‑fold, and 2.4-fold QoL-W deterioration within 4, 4–12, and >12 weeks post-infection (p < 0.05). Subjects with QoL-W decline >12 weeks were younger, mostly women, had more brain fog symptoms, and higher platelet counts. Multivariable models with self-reported brain fog symptoms (responding coherently and recalling recent information), age, and sex exhibited good discriminatory power for QoL-W impairment (area under the receiver operating characteristic curve 0.846, 95% CI: 0.780–0.912). Conclusions This study highlighted that in non-high-risk subjects hospitalized during the first 2 pandemic’s waves: 1) brain fog was common, affecting nearly half of individuals, and impacting QoL-W >12 weeks after initial infection, 2) after 3 months of COVID-19 onset, the decline in QoL-W was primarily attributed to brain fog symptoms rather than demographic factors, health conditions, admission status, and laboratory findings, 3) components of brain fog, such as answering in an understandable way or recalling new information increased the likelihood of significantly lower QoL-W up to tenfold, 4) biochemical indicators, such as the first hs-cTnI level, might predict the risk of experiencing brain fog symptoms and indirectly decreased QoL-W >12 weeks after COVID-19 onset. Occupational medicine practitioners should pay particular attention to younger and female subjects after COVID-19 complaining of problems with answering questions in understandable way or recalling new information as they have an increased risk of QoL-W impairment.

Opis:
Nearly two years into the pandemic, a large body of data has emerged on how COVID-19-positive patients function with the viral infection. It is now known that the virus targets the central nervous system(CNS). As a result, in addition to the expected common health complaints, patients display cognitive and emotional problems. Cognitive deficits should be expected particularly in patients who have arrived at an intensive care unit as a result of respiratory failure, in patients suffering from comorbid neurodegenerative diseases and respiratory conditions, as well as in the elderly. However, these may also occur in patients with moderate to mild symptoms as well as in those of a younger age. The cognitive impairment has an unknown profile. Given the hypothesised hippocampal vulnerability to the SARS-CoV-2 virus, one might expect particular difficulties with memory, attention, information processing, and executive functions. With varying neuropsychological and emotional problems, convalescents in trying to return to their social, family and professional life require professional psychological assistance. The role of neuropsychologists is here crucial. Indeed, many patients will require a detailed, multifaceted neuropsychological diagnosis that will form the basis for subsequent neuropsychological rehabilitation. An early detection of neuropsychological manifestations could modify the risk of subsequent irreversible impairment and further neurocognitive decline.

Opis:
Diabetes stands as the most widely recognized acute disease globally, resulting in death when it is not treated in an appropriate manner and time. We have developed a closedloop control system that uses continuous glucose, carbohydrate, and physiological variable data to regulate glucose levels and treat hyperglycemia and hypoglycemia, as well as a hypoglycemia early warning module. Overall, the proposed models are effective at predicting a normal glycemic range from >70 to 180 mg/dl, hypoglycemic values of <70 mg/dl, and hyperglycemic value of 180 mg/dl blood sugar levels. We undertook a seven-day, day-and-night home study with 15 adults. Initially, we started with checking insulin levels after meal consumption, and later, we concentrated on how our system reacted to the physical activity of the patients. Evaluation was conducted based on performance parameters such as precision (0.87), recall (0.87), F-score (0.82), delay (26.5±3), and error size (1.14±2).

Opis:
It is a hot topic to investigate resource allocation in fog computing. However, currently resource allocation in fog computing mostly supports only fixed resources, that is, the resource requirements of users are satisfied with a fixed amount of resources during the usage time, which may result in low utility of resource providers and even cause a waste of resources. Therefore, we establish an integer programming model for the time-varying multidimensional resource allocation problem in fog computing to maximize the utility of the fog resource pool. We also design a heuristic algorithm to approximate the solution of the model. We apply a dominant-resource-based strategy for resource allocation to improve resource utilization as well as critical value theory for resource pricing to enhance the utility of the fog resource pool. We also prove that the algorithm satisfies truthful and individual rationality. Finally, we give some numerical examples to demonstrate the performance of the algorithm. Compared with existing studies, our approach can improve resource utilization and maximize the utility of the fog resource pool.

Opis:
Cloud computing provides centralized computing services to the user on demand. Despite this sophisticated service, it suffers from single-point failure, which blocks the entire system. Many security operations consider this single-point failure, which demands alternate security solutions to the aforesaid problem. Blockchain technology provides a corrective measure to a single-point failure with the decentralized operation. The devices communicating in the cloud environment range from small IoT devices to large cloud data storage. The nodes should be effectively authenticated in a blockchain environment. Mutual authentication is time-efficient when the network is small. However, as the network scales, authentication is less time-efficient, and dynamic scalability is not possible with smart contract-based authentication. To address this issue, the blockchain node runs the skip graph algorithm to retrieve the registered node. The skip graph algorithm possesses scalability and decentralized nature, and retrieves a node by finding the longest prefix matching. The worst time complexity is O(log n) for maximum n nodes. This method ensures fast nodal retrieval in the mutual authentication process. The proposed search by name id algorithm through skip graph is efficient compared with the state-of-art existing work and the performance is also good compared with the existing work where the latency is reduced by 30–80%, and the power consumption is reduced by 32–50% compared to other considered approaches.

Opis:
The purpose of this study is to evaluate the effectiveness of functional neuromarker- based electroencephalographic training with neurofeedback (EEG-NFB) for a patient with dysexecutive syndrome following neurosurgical operation of two brain aneurysms of the left and right middle cerebral artery (MCA) detected after COVID-19 disease. A right-handed, 56-years-old, not vaccinated, patient, became infected with SARS- CoV-2 and contracted COVID-19 with the manifestation of respiratory symptoms, high fever, dyspnea and low saturation of 79% Sa02. She was hospitalized at the Infectious Disease Unit, where a positive RT PCR test for COVID-19 was confirmed. The acute phase of COVID-19, during which oxygen therapy was administered, lasted two weeks and was complicated by brain fog and transient hypertension (175/100). There were no signs of focal damage to the central nervous system. She was discharged home in a good general and neurological condition. After returning home, the patient was unable to cope with daily functioning, as she said her brain fog continued to persist, manifesting itself as executive dysfunction. Eight weeks after the infection, the patient's neuropsychiatric condition worsened. On CT and MRI examination of the cerebral vessels, she was diagnosed with the presence of two aneurysms located on the left and right middle cerebral arteries (MCA). She was operated on at the Department of Neurosurgery and Neurotraumatology, where a pterional craniotomy and clipping of both brain aneurysms was performed. The Yasargil titanium clip was placed on the aneurysm neck. During the surgery procedures, performed two months apart, there were no signs of a history of subarachnoid haemorrhage and the post-operative period was uneventful, except for a drooping right-eye eyelid (after the second surgery) with a tendency to improve. Each time, the patient was mobilized and walked independently and was discharged home in a good general condition, with no neurological symptoms, except for executive dysfunction. Approximately five months after the SARS-CoV-2 infection (four weeks after the second surgery), her executive dysfunction worsened. Neuropsychological testing using Mindstreams™ Interaction Computer Tests revealed moderate Dysexecutive Syndrome (DES), while neurophysiological testing using qEEGs, ERPs and sLORETA tomography, a functional neuromarker of frontotemporal area dysfunction. The EEG pattern was characterized by excessive, slow (about 6 Hz) activity in frontotemporal areas, which indicated the progressive loss of cognitive control over time. The patient was offered an electroencephalographic training protocol with neurofeedback (EEG-NFB) based on the detected functional neuromarker, which reduced DES. The improvement achieved during therapy was statistically significant [compared to the normative database (Human Brain Index, HBI)]. In effect, the patient's quality of life improved, as she herself pointed out. Her symptoms of brain fog and DES disappeared and she returned to her previous work as a waitress. The Human Brain Index (HBI) methodology can be successfully used in the neurodiagnosis and implementation of individualized electroencephalographic training with neurofeedback (EEG-NFT) for patients with executive dysfunction after contracting longCOVID.

This study aimed to determine the performance of modified slow sand filter (SSF) media with blood clam shells (Anadara granosa) and activated carbon to remove turbidity, TSS, TDS, and FOG on the food court wastewater. The concentration of water pollutant parameters processed by SSF was determined based on Indonesia water quality standards, as well as knowing the optimum operational parameters of intermittent slow sand filter with Response Surface Methodology (RSM). The research data was processed using the Optimal type (custom) design which consisted of independent factors including the type of filter media, the addition of bacteria to the grease trap pre-treatment unit, and running time, as well as the research response in the form of the effectiveness of removing turbidity, TSS, TDS, and FOG. The reactor was operated intermittently (48 hours) for a maximum of 22 days and the concentration of pollutant parameters was calculated using the Standard Methods. The results of the Analysis of Variance (ANOVA, p<0.05) in the 2FI model of the study showed that there was a significant effect of all independent factors on the effectiveness of removing all water pollutant parameters. The most optimal operational parameters were achieved with the type of activated carbon media, the addition of Bacillus sp. in the grease trap pre-treatment unit in the amount of as much as 1%, and the detention time of 4 days, with the effectiveness of removing turbidity reaching 39.53%; TSS 45.25%; TDS 19.30%; FOG 61.35%.

The unpredictable and huge data generation nowadays by smart devices from IoT and mobile Crowd Sensing applications like (Sensors, smartphones, Wi-Fi routers) need processing power and storage. Cloud provides these capabilities to serve organizations and customers, but when using cloud appear some limitations, the most important of these limitations are Resource Allocation and Task Scheduling. The resource allocation process is a mechanism that ensures allocation virtual machine when there are multiple applications that require various resources such as CPU and I/O memory. Whereas scheduling is the process of determining the sequence in which these tasks come and depart the resources in order to maximize efficiency. In this paper we tried to highlight the most relevant difficulties that cloud computing is now facing. We presented a comprehensive review of resource allocation and scheduling techniques to overcome these limitations. Finally, the previous techniques and strategies for allocation and scheduling have been compared in a table with their drawbacks.

Opis:
The 2009 public debt crisis onset triggered a fundamental constitutional transformation of the European Union (EU). What is the link between this transformation and the enlargement policy? The authors of the article seek an answer to this question. The main thesis is that the method of impersonal authoritarianism in dealing with the Eurozone crisis spilled over into the EU enlargement policy. On the one hand, we consider the systemic reasons for turning the enlargement policy into an instrument of geopolitical control of the states on the outer periphery. On the other hand, the problem is considered from the point of view of Serbia’s interest as an EU membership candidate country. The authors conclude that opening space for innovation and flexibility in relations would be in the mutual interest of the EU and candidate countries. The analysis of the new enlargement policy reform proposal examines the readiness of European leaders to open the door for a new type of relations with the candidate countries that would correspond to today’s European reality of the historical interregnum.

Opis:
Fog networks facilitate ultra-low latency through the use of data availability near the network edge in fog servers. Existing work in fog networks considers the objective of energy efficiency and low latency for internet-of-things (IoT) for resource allocation. These works provide solutions to energy efficiency and low latency resource allocation problem without consideration of secure communication. This article investigates the benefits of fog architecture from the perspective of three promising technologies namely device-to-device (D2D) communication, caching, and physical layer security. We propose security provisioning followed by mode selection for D2D-assisted fog networks. The secrecy rate maximization problem is formulated first, which belongs to mixed-integer nonlinear programming (MINLP) problem. It is NP-hard, that is why an exhaustive search for finding the solution is complex. Keeping in view the complexity, a nonlinear technique namely outer approximation algorithm (OAA) is applied. OAA is a traditional algorithm, whose results are compared with the proposed heuristic algorithm, namely the security heuristic algorithm (SHA). Performance of the network is observed for the different numbers of eavesdroppers, IoT nodes, and fog nodes.

Opis:
Celem pracy jest określenie wpływu cyrkulacji atmosfery na występowanie mgieł na wybranych lotniskach w Polsce. Wykorzystano dane z okresu 1981-2015, obejmujące liczbę godzin z mgłą w poszczególnych dniach na stacjach w Szczecinie, Gdańsku, Poznaniu, Warszawie, Wrocławiu, Krakowie i Rzeszowie. Typy cyrkulacji atmosferycznej zostały opisane zgodnie z typologią J. Lityńskiego. Dodatkowo wykorzystano dane uzupełniające, obejmujące Numeryczny Model Terenu (DEM), mapy sieci rzecznej i zbiorników wodnych w Polsce oraz mapę pokrycia terenu CORINE Land Cover 2012. Z przeprowadzonych analiz wynika, że istotną rolę w występowaniu dni z mgłą odgrywają kierunki adwekcji powietrza. W większości przypadków najwięcej dni z mgłą występowało podczas adwekcji powietrza z kierunków południowych, a najmniej z północnych, niezależnie od pory roku. Zróżnicowanie przestrzenne występowania mgły w określonym typie cyrkulacji jest spowodowane między innymi wpływem warunków lokalnych. Największy wpływ wykazują rzeźba terenu i obecność zbiorników wodnych.
The aim of this paper is to examine the influence of atmospheric circulation on the occurrence of days with fog at the airports in Poland. The data included the number of hours with fog on particular days in the period of 1981-2015 on the stations in Szczecin, Gdańsk, Poznań, Warszawa, Wrocław, Kraków and Rzeszów. The study uses the circulation typology by J. Lityński. Additionallny, Digital Elevation Model, map of rivers and water reservoirs in Poland and land cover map CORINE 2012 were used in this research. The occurrence of days with fog in particular circulation types was assessed with the frequency and conditional probability. It was found that the directions of air advection play an important role in the occurrence of days with fog. In most cases the most days with fog occurred during air advection from southern directions and the least from northern ones. The spatial diversity of fog occurrence in a given type of circulation is caused by the influence of local conditions. The strongest influence is exerted by the relief and the presence of water reservoirs.

Opis:
Extremely dense fog event was studied on the 3rd December 2001, which occurred in the city of Apatity, the Kola Peninsula, northwestern Russia. Fog had low visibility (30–50 m) and lasted 17 h. Variations of atmospheric pressure and electric field before and during the fog event were measured. Multiple Taper Method (MTM) of spectral analysis has revealed pulsations of the atmospheric electric field in the frequency band of 0.007–0.05 Hz with a power-law turbulence spectrum. MTM and wavelet decomposition analysis results indicate the appearance of two types of atmospheric pressure oscillations under the fog conditions: low-frequency variations with periods of internal gravity waves and a substantial increase in pulsation intensity (more than an order of magnitude) in the high frequency (0.03–0.35 Hz) range. These results may help to improve the understanding of the microphysics of fog formation, development, and dissipation. High-frequency pulsations generation of atmospheric pressure under the fog conditions is also of interest because their period is close to the range of infrasonic oscillations, which can have negative consequences for human health.

Opis:
This article reviews some very recent publications pertaining to the long-term neuropsychological effects of COVID 19 (neuroCOVID). Although such publications are now appearing in large numbers on a daily basis, we still do not have enough data of sufficient quality to enable any firm conclusions to be reached. At this point, then, the authors determined to consider the main questions that have emerged so far, as we wait for the results of more thorough research in the future. The article takes up three main questions: (1). What is the etiology and pathomechanism of the neuropsychological symptoms caused by SAR-CoV-2 infection, and what is the prognosis? (2). Of the reported symptoms, which ones should be considered pathognomonic, and what is their significance? (3). What can clinicians do for their patients now, in the absence of the kind of data we need to answer either of the other two questions with any degree of certainty? Although it is not possible at this point in time to answer any of these questions definitively, it does seem increasingly clear that the problems are complex, not only at the cellular level, but also (and perhaps more so) at the conceptual level. The common report of “brain fog,” for example, very much needs to be explored, in order to determine what this vague term actually means, and what, if anything, can be done to allevi- ate it. This will require us to rethink such basic concepts as consciousness, and also to commit ourselves to genuinely interdisciplinary study.
