Detecting patterns of coordinated news article dissemination

This study aims at devising methods for detecting coordination among content spreaders at scale. We focus on methods which uncover the latent structure of the content dissemination networks from the time-series of publications. We identify the advantages of generative models, especially self-exiting stochastic processes, for modeling information cascades and detecting structural patterns in groups of events. We validate the most popular of these models – the Multivariate Hawkes processes – on a large dataset of news websites and achieve an improvement in comparison to simpler baselines, e.g., cosine similarity between time-series of publications

Justification of using Computed Tomography and Magnetic Resonance Imaging for Deep Venous Thrombosis and Pulmonary Embolism

Deep vein thrombosis (DVT) is a medical condition, occurs when a blood clot forms in a deep vein and pulmonary embolism (PE) occurs when a blood clot gets lodged in an artery in the lung, affecting blood flow to part of the lung.The frequencies of using computed tomography (CT) and magnetic resonance imaging (MRI) to diagnose deep venous thrombosis and pulmonary embolism is increasing day by day.Both the technics are noninvasive and provide prompt results. But there are a good number of alternative technics for the same purposes. That is why, till now scholars and respective professionals are interested to know more about the justification and comparative effectiveness of CT and MRI in detecting DVT and PE.This review aimed to analyze the history of several detecting methods for DVT and PE and to dig out the clear concepts about the effectiveness and patient compliances of CT and MRI in detecting deep venous thrombosis and pulmonary embolism. For proper analysis a lot of research as well as meta-analysis had been studied.From this article besides scholars and professionals, general readers will get a clear concept about the features, effectiveness and justifications of CT and MRI in treating DVT and PE

Das Ernennungsverfahren unter "Quarantäne-Bedingungen" könnte den Staatsdienst der Ukraine in die Zeit von Janukowytsch zurückwerfen

Im Rahmen der im Frühjahr in der Ukraine verhängten Quarantäne-Maßnahmen gegen die Ausbreitung des Coronavirus beschloss das Ministerkabinett im April auch eine weitreichende Änderung des 2016 reformierten Ernennungsverfahrens für Staatsämter: Der Auswahlprozess wurde verkürzt und vereinfacht: anstelle eines aufwändigen mehrstufigen Bewerbungsverfahrens reicht ein einfaches Bewerbungsgespräch. Das erhöht das Korruptionsrisiko und könnte nach Ende der Quarantänemaßnahmen zu einem verwaltungstechnischen Vakuum führen. Der nachfolgende Artikel basiert auf einer Auswertung der zwischen April bis Juli 2020 erfolgten Entlassungen und Ernennungen und analysiert die Konsequenzen des vereinfachten Ernennungsverfahrens

Multiprobiotic therapy from childhood prevents the development of nonalcoholic fatty liver disease in adult monosodium glutamate-induced obese rats

Considering the association between microflora and obesity, and the significantly higher prevalence of non-alcoholic fatty liver disease (NAFLD) in obese people, the aim of our study was to investigate the preventive effect of multiprobiotics on the monosodium glutamate (MSG) induced NAFLD model, in rats. The work was carried out on 60 rats placed into three groups: the Control group, the MSG-group and the MSG-probiotic group. The MSG-group and the MSG-probiotic group were injected with 4 mg/g of MSG subcutaneously neonatally on the 2nd-10th days of life. The MSG-probiotic rats were also treated with 140 mg/kg of multiprobiotic “Symbiter” from the 4th week of life. In the 4-month-old rats, biochemical and morphological changes in liver were assessed, and steatosis was confirmed by the NAFLD activity score (NAS). Our results reveal that the multiprobiotic lowered total NAS, the degree of steatosis and the liver lobular inflammation caused by MSG. It also brought about decreased liver total lipids and triglycerids content, as well as decreased visceral adipose tissue mass. However, there was no difference in the liver serum biochemical indicators between all experimental groups. The obtained data does suggest the efficacy of probiotics in the prevention of NAFLD

Does Physical Activity Matter for the Mental Health of University Students during the COVID-19 Pandemic?

Research indicates that university and college students are at higher risk of experiencing mental health problems than other populations. This study aims to examine the relationship between Physical Activity (PA) and the mental health of Ukrainian university students during the Corona Virus Disease 2019 (COVID-19) pandemic lockdown. The conventional sample consisted of 1512 students from 11 Ukrainian universities, with a mean age of 20 years (M = 20.06, SD = 3.05) and 69% of whom were female. The cross-sectional online survey was disseminated through the most popular social media channels in Ukraine (i.e., Facebook, Viber, Telegram) and included the Generalized Anxiety Disorder (GAD-7) scale to measure anxiety and the Patient Health Questionnaire (PHQ-9) to assess depression. Data were collected from 14 May to 4 June 2020 during the COVID-19 pandemic outbreak in Ukraine. Among university students, 43% were engaged in PA ≥ 150 min weekly, 24% met the criteria of GAD, and 32% met the criteria of depression. More students were involved in PA before the COVID-19 outbreak than during the national lockdown. Students with anxiety and depression were almost two times less likely to engage in PA than their counterparts without mental health disorders. The inactive group had higher scores of anxiety and depression than the physically active group. The relationship of PA with anxiety and depression was statistically significant but weak during the COVID-19 pandemic
