Adjoint Tomography of Northeast Japan Revealed by Common-Source Double-Difference Travel-Time Data
Authors: Chen Jing , Chen Guoxu , Wu Hao , Yao Jiayuan , Tong Ping
Published: March 2022

We present the wave equation-based adjoint tomography of northeastern Japan using common-source double-difference travel-time data. More than 30,000 high-quality first P-wave arrivals from 117 local earthquakes recorded by 713 seismic stations are included in the inversion, generating more than 350,000 double-difference travel times of first P-wave arrivals. In comparison with commonly used travel-time data, the common-source double-difference travel times are insensitive to source parameters and source-side structures but place enhanced constraints on receiver-side structures. As a result, these robust double-difference travel times generate a reliable VP model down to a depth of 120 km. Our inversion results clearly show crustal low-velocity anomalies beneath the volcanic arc. The subducting Pacific slab is illuminated as a landward-dipping high-velocity anomaly, and the arc magmatism in the mantle wedge is shown as low-velocity anomalies. Thanks to the newly operated Seafloor Observation Network (S-net), prominent high-velocity bodies are detected in the fore-arc mantle wedge at depths of 30–60 km. These abnormal high-VP bodies indicate a low degree of serpentinization in the fore-arc mantle wedge at low temperatures, correlating well with the previous finding that the uppermost mantle in the Kuril and Tohoku fore-arc is cold and dry. Our inversion results reveal reliable tectonic features in the subduction zone beneath northeastern Japan, suggesting that wave equation-based common-source double-difference travel-time adjoint tomography is an effective and robust method to illuminate detailed structures of the crust and uppermost mantle.
Understanding How Time and Memory Interact with Network Topology in Real-World Systems with Selected Applications
Authors:   , Craig Adam George , Kriete Andres
Published: March 2022

Networks are an increasingly common way of summarizing complex systems, especially those in which interacting components transmit information. We here show that reintroducing motion and memory to these static representations of nodes and edges provides new insights into network structure. We analyzed memory biased random walks (MBRW) to show that spectral dimension, a random-walk based measure of network dimensionality, relate more strongly to the kinds of community structure found in a wide variety of real-world biological networks than do shortest-path based methods that analyze static network structure to calculate network fractal dimension and that MBRW generalized spectral dimension is a more effective means of exploring the heterogeneity of such networks than is simple random walk (RW) spectral dimension. Additionally, we find that all the measures considered show a pronounced finite size effect over the range of sizes within which the real-world networks fall (fewer than 10,000 nodes), reflecting the disparity between the infinite recursive hierarchy of structure implied by the concept of fractality and the limited sizes of networks describing real-world systems. However, the systematic study of complex systems, including the scientific community itself, demands not only analytical methods but infrastructure for managing the descriptions of their components and interactions. To this end, we propose an approach to using the Nexus-PORTALDOORS (NPDS) metadata and data management system to store semantic representations of the statements and attributions of those statements found in scholarly research articles in order to better trace the flow of ideas from paper to paper and compare it to the network of citations in order to measure adherence to good citation practices and promote proper attribution in a way that will eventually be able to scale with the ever-growing output of the modern biomedical science and engineering community.
The empty shell of social dialogue
Authors: Árendás Zsuzsanna , Hungler Sára
Published: March 2022

The European Social Model involves among other things: fundamental social rights, social protection and social dialogue. The neoliberal path chosen by Europe combined with the financial crisis led to the introduction of austerity measures that endanger key elements of that model. Europe and its Member States have common and national mechanisms to ensure distributive justice, citizens’ participation and the continuity of the European Social Model even when it is threatened by international financial conditions or the political choices of its rulers. As a part of the ETHOS Struggles for Justice – Impact of Social and EU Charters in times of crisis project, our research aims to answer two leading questions: to what extent is the national social dialogue a democratic instrument that uses horizontal and democratic processes and whether it is a powerful instrument for the preservation of the European Social Model?Our paper reports on the actual status and functioning of social dialogue as a mechanism to produce a more effective enjoyment of labour rights between the different political and social actors in Hungary. We interviewed key actors of trade unions and confederations, lead character of an employers’ association, and analysed the relevant international and national legal framework concerning social dialogue. The case studies focus on two special – strongly polarised and politicised – areas: healthcare and public education. Interviews conducted with sectoral representatives aim to find out the different perceptions about the practices of social dialogue and social partners’ views on the role of the state in social dialogue.

A hiánygazdaság, a rugalmatlan állami vállalatok árnyékában erősödő piac, a régió többi országát megelőző reformok már a nyolcvanas évek Magyarországán a felemelkedés vissza nem térő lehetőségét teremtették meg azoknak, akik a piacon eladható tudással rendelkeztek, vagy nyitottak voltak ilyet elsajátítani.

Dolgozatunkban két – a rendszerváltás folyamatába ágyazódott – esetet mutatunk be, amikor a szereplők éltek a történelemadta kivételes lehetőséggel, s karrierjük meredeken és gyorsan emelkedett magasra a nyolcvanas évek végén, a kilencvenes évek elején anélkül, hogy a tőketulajdonosi jogosítványok újraelosztásában részt vettek volna. A két eset bemutatása során arra fókuszáltunk, hogy egyrészt mik voltak azok az erőforrások, amik (verseny)előnynek bizonyultak, illetve hogy ezek segítségével milyen módon tudták megragadni a helyzet kínálta lehetőségeket.

Problems of Construction of Receiving Stations for Wastewater from Vessels in Marinas and Ports
Authors: Burić Emil , Kovačić Mirjana
Published: March 2022

The paper presents the legislation of Croatia and the EU on the prevention of sea water pollution by
wastewater from boats, yachts and other smaller vessels. The authors analyse the key legal determinants
and explain their impact on the pollution caused by the discharge of wastewater from boats, yachts and
other smaller vessels. The specifics of the Adriatic Sea with regard to potential pollution are determined
and the previous experiences and effects on the environment are explained.
It’s a fact that the national legislation is not effective enough in matters of marine environmental
protection, which is why the authors propose changes and qualitative solutions. A review of previous
research has shown that there are appropriate solutions and interest from boaters in terms of using
appropriate receiving stations for the reception of wastewater from vessels and boats. A SWOT analysis
was made where the strengths and opportunities for the establishment of an appropriate system of
receiving stations were identified.

Feeding America Eastern Wisconsin (FAEW) distributed 81% more food to community members in need during the COVID-19 pandemic than in the prior year. Though systems were in place to manage food receipt and distribution data, social distancing requirements and technological barriers revealed inefficiencies in how these data were being utilized. In pursuit of data-driven decision making and in the context of a global pandemic, FAEW partnered with Marquette University data scientists through an industry supported grant. Applying newly learned skills in Business Intelligence, students have produced detailed reports of data cleanliness in FAEW’s source systems to improve underlying data quality and better support analytic efforts. Additionally, students have synchronized Human Centered Design Thinking and Visual Analytics to produce an interactive application that is being used to optimize inventory management, storage availability, and product distribution. Finally, students are utilizing Business Analytics techniques such as supervised and unsupervised data mining to provide new insights about food receipt and distribution patterns that will have a sustainable impact on FAEW operations. This unique partnership is providing experiential learning opportunities for students, tangible data science solutions that FAEW will use to ensure best practices, and real-world solutions to collaboratively end hunger in our communities.

Authors: Anzorov V.A. , Moryakina S.V.
Published: March 2022

The work is devoted to the study of the impact of pregnancy on the state of the cardiovascular system in women. The process of pregnancy is accompanied by significant changes in the rhythm of the heart performance and blood pressure, and the duration of the ECG waves and segments are not significantly fluctuated. The heart rhythm, gradually increasing, reaches its maximum value of 87.3 beats per minute (P < 0.001) in the last trimester, in women of the reference group 69.8. The minimum level of systolic blood pressure is 105.6 mm Hg, diastolic 69.5 mm Hg, detected in the second trimester of pregnancy, and the maximum - 146.4 and 88.0 mm Hg, respectively in the third one. The time of the P wave during pregnancy tends to decrease. The minimum time 0.151 s and maximum 0.162 in the reference is used for excitation from the atria to the ventricles in the third trimester. The coverage time of the ventricular excitation during pregnancy is reduced. Thus, the excitation in the third trimester occurred in 0.077 s, and 0.083 s in the reference group. In the reference group of women, the duration of QT was 0.346 s, and 0.331 s by the end of pregnancy.

Published: March 2022

Autotransplantation of a free flap of the gracilis muscle is currently actively used in reconstructive surgery for persistent prosoplegia, injuries of the brachial plexus, for plastic closure of defects in the upper lip, and in the treatment of pelvic sepsis. This study provides important information about the anatomical features of the gracilis muscle and its neurovascular bundle, which are highly variable. The study of the anatomical and topographic features of this fine thigh muscle was carried out on a sectional study of 25 corpses of both sexes, 50 lower limbs. The present study demonstrates that the median value of the total length of m. Gracilis, the length of its muscular part, as well as the length of the tendon were 452.25 (439.7; 462.0); 225.3(208.1;239.0); 230.5 (213.0; 244.4) mm, respectively. The number of vascular pedicles included in m. Gracilis, ranged from 1 to 5. In 86% of the cases, the deep femoral artery formed the dominant vascular pedicle, and in 14% of cases, it was the medial circumflex artery. Small secondary vascular pedicles originated from the descending genicular artery or the anterior branch of the obturator arter: from the basin of the internal iliac artery. The length of the main feeding artery varied from 76 to 134 mm, the median value was 100.5(90;110) mm, and its diameter ranged from 1.4 to 2.1 mm (M = 1.9(1.8;2, 0) mm. The innervation of the fine muscle of the thigh was carried out by the anterior branch of the obturator nerve, which in 82% of the cases was represented by a single trunk; less often a loose type of structure was observed. The proper nerve was located at a distance of 108.5 (96; 117) mm from the origin of the muscle; its diameter was 2.1 (1.9; 2.2) mm. Knowledge of the topographic and anatomical relationships of the neurovascular bundle with the surrounding formations, variants of its individual anatomical variability are the key to successful reconstructive surgery.

Published: March 2022

Based on the results of our own research, examination of scientific dossier materials and reference literature data, it was established that dry powder Mungoltin made from the shoots of mung beans produced by Oriona-Scorpion LLC (Uzbekistan) contains a sufficient amount of protein, minerals, vitamins and dietary fiber, does not have a negative impact on the health status of experimental animals and does not result in functional and material cumulation. Acute systemic toxicity testing with intragastric administration of Mungoltin was carried out in 18 adult white male rats. Animals were divided into 4 groups. The animals of the first group received a nutrition dose of 5000 mg/ kg; the white rats of the second group were administered with a dose of 7500 mg/kg, and the rodents in the third group were given a dose of 10000 mg/kg, respectively. The animals in group 4 (the reference group) received distilled water. Upon a prolonged intragastric exposure to Mungoltin, no changes in biochemical parameters were detected. The activity indicators of alkaline phosphatase, trans-aminase enzymes and total protein in the blood serum did not differ significantly from those found in the reference group. Therefore, using Mungoltin will not cause a cytotoxic effect in relation to normal highly proliferating cells in an organism. The results of histomorphological studies of tissues of internal organs upon intragastric administration of Mungoltin within 30 days confirm the absence of toxic effects. According to toxicity parameters under the conditions of the above acute experiments, Mungoltin can be attributed to class 5 practically as a non-toxic substance.

As the formation of brachial plexus involves numerous nerve roots, it is more common than rare to find variations in the formation and its branching pattern. Innumerable variations in the formation of lateral cord of brachial plexus and the branches of the lateral cord of brachial plexus are reported. This study is done with an intension to specifically look into the possible variations in the formation and branches of the lateral cord of brachial plexus only. The present study was carried on cadavers during undergraduate dissection, in the Department of Anatomy, Velammal Medical College, Annupanadi, Madurai, Tamilnadu India. In the present study The cadavers were dissected out to find the branching pattern of the Lateral cord and the observations were analysed, many variations in the branching patterns were observed, significant one being the musculocutaneous nerve being absent, coracobrachialis being supplied by branch from lateral root of median nerve, in another musculocutaneous nerve ends by supplying only coracobrachialis and the rest are supplied by the branches from median nerve. The frequency of anomalies found in the arrangement and distribution of lateral cord and its branches makes this anatomic region complicated with regard to surgical approaches.

Published: March 2022

The Distributed Denial of Service (DDoS) attack is a serious cyber security attack that attempts to disrupt the availability security principle of computer networks and information systems. It's critical to detect DDoS attacks quickly and accurately while using as less computing power as possible in order to minimize damage and cost efficient. This research proposes a fast and high-accuracy detection approach by using features selected by proposed method for Exploitation-based DDoS attacks. Experiments are carried out on the CICDDoS2019 datasets Syn flood, UDP flood, and UDP-Lag, as well as customized dataset. In addition, experiments were also conducted on a customized dataset that was constructed by combining three CICDDoS2019 datasets. Pearson, Spearman, and Kendall correlation techniques have been used for datasets to find un-correlated feature subsets. Then, among three un-correlated feature subsets, choose the common un-correlated features. On the datasets, classification techniques are applied to these common un-correlated features. This research used conventional classifiers Logistic regression, Decision tree, KNN, Naive Bayes, bagging classifier Random forest, boosting classifiers Ada boost, Gradient boost, and neural network-based classifier Multilayer perceptron. The performance of these classification algorithms was also evaluated in terms of accuracy, precision, recall, F1-score, specificity, log loss, execution time, and K-fold cross-validation. Finally, classification techniques were tested on a customized dataset with common features that were common in all of the dataset’s common un-correlated feature sets.

Błąd antropologiczny to igranie z ogniem miłości
Authors: Grygiel Stanisław
Published: March 2022

Artykuł analizuje problematykę błędu antropologicznego przez pryzmat miłości małżeńskiej. Autor pokazuje, w jaki sposób błąd antropologiczny narusza prawdę o człowieku stworzonym mężczyzną i kobietą oraz ich wzajemne bycie darem zobowiązującym do odpowiedzi. Ostatecznie błąd antropologiczny niszczy w człowieku dwa paradygmaty miłości: niszczy różnicę ontologiczną, łączącą człowieka ze Stwórcą, oraz różnicę seksualną, łączącą mężczyznę i kobietę w „jedno ciało”. Niszcząc historię miłości, w konsekwencji daje on początek ideologiom, które – pełniąc funkcje metafizyki – nie znają daru, a samą historię miłości przekształcają w historię zaspokajania takiej lub innej potrzeby, niekiedy sprzeciwiającej się godności osoby.

We contacted 294 students, of which 199 responded. The data were analyzed and presented using Microsoft Excel.
Results – The findings of the study showed the keen interest of the students in library resources and services. It also showed that the students were not fully satisfied with the current library space and working hours. They wanted enhanced quiet areas and collaborative spaces where information experts help them use the current technology to improve their learning experience. Based on the gathered data analysis, an IC model for redesigning the existing library has been recommended.
Conclusion – The present study was the first step in research on ICs in the Indian context. This pilot study captured the perception and expectations of all levels of students: postgraduate, working executives, and senior-level executives. Most of the suggestions have been incorporated into the plan. With very few construction changes and new furniture, this model can be easily implemented in a small academic library without discarding the old furniture.

The case report of a patient with post-sternotomy mediastinitis is presented. A successful case of treatment of such a formidable complication after cardiac surgery was demonstrated. Success in the treatment of such patients depends on the complete cupping inflammatory process in the site of operation, as well as chest wall reconstruction. The positive clinical effect of vacuum-assisted dressings in the treatment of post-sternotomy mediastinitis is shown. The vertical rectus abdominis myocutaneous flap was used as a plastic material to cover a defect in the chest wall. The course of surgery and the result of treatment are described in details. To date, the surgical society has not developed a generally accepted tactic in the treatment of poststernotomy mediastinitis, both at the stage of arresting the infectious process, and in the process of reconstructive and restorative intervention. In practice, along with alloplastic materials, synthetic and metal implants are used. The autologous tissues include muscle flaps and the greater omentum. In thoracic surgery, the rectus abdominis can serve as an alternative to omentoplasty for extended chest wall defects.

Objective. Development of a non-invasive assessing diagnostic and severity grading accuracy of portal hypertension in cirrhosis of the liver. Methods. To identify diagnostically significant indicators, a statistical analysis of the data of laboratory and instrumental diagnostics was carried out in 60 patients with liver cirrhosis. The followingbiochemical indicators weredetermined: general and biochemical blood tests, coagulogram, general urine analysis; the level of interleukin-6 (IL-6), matrix metalloproteinases 1 and 9 (MMP-1, MMP-9), tissue inhibitor of matrix metalloproteinase 1 (TIMP-1), hepatocyte growth factor (HGF); abdominal ultrasound examination, esophagogastroscopy. The index of the ratio of the number of blood platelets (N×109 / L) to the transverse size (D) of the spleen in millimeters (PSR - Platelet count to Spleen diameter Ratio) was calculated: PSR = NTr / D spleen. Results. The following indicators turned out to be diagnostically significant (predictive values based on ROC analysis are presented): blood levels of IL-6 (>19.9 pg/ml), MMP-1 (>8.06 ng/ml), cholesterol (≤4,5mmol/L), portal vein diameter (>13 mm), PSR (≤1.89). Diagnosticmethods for cirrhosis and portal hypertension was developed, based on a point assessment of a set of laboratory and instrumental criteria (AUC = 0.931; p <0.001). The method can be used in a complex of medical services aimed at diagnosis of portal hypertension severity in patients with cirrhosis of the liver, as well as medical prevention of life-threatening complications of the disease. Conclusion. The developed method makes it possible to identify patients with a «severe» form of portal hypertension, to recommend an unscheduled FEGDS with an endoscopic assessment of the risk of bleeding, and to carry out preventive and therapeutic procedures. If a low probability of a “severe” form of PH is identified, FEGDS should be refrained from if the patient has absolute or relative contraindications to the use of this diagnostic method. The method can be used in a complex of medical services aimed at diagnosing the severity of portal hypertension against the background of liver cirrhosis. What this paper adds For the first time, a method for diagnosis of portal hypertension in liver cirrhosis has been developed. It is based on a score assessment of a set of laboratory and instrumental criteria, including blood levels of interleukin-6, matrix metalloproteinase-1, cholesterol, platelet count, portal vein diameter and transverse size of the spleen. The method can be used in a complex of medical services aimed to estimate the severity of portal hypertension in cirrhosis of the liver, as well as medical prevention of life-threatening complications of the disease.

Background: The purpose of the current study was comparing pregnancy outcomes for natural cycle in vitro fertilization (IVF) per fresh embryo transfer (ET) and oocyte pick-up (OPU) in intrauterine insemination (IUI).
Methods: This was a retrospective cohort study of women who underwent either IUI (n=246) or OPU with fresh ET for natural cycle IVF (n=291), conducted between April 2017 and February 2018 at the Center for Reproductive Medicine and Implantation Research, Sugiyama Clinic Shinjuku, Tokyo, Japan. Patients in both groups did not receive ovarian stimulation and luteal support; gonadotropin-releasing agonist spray was administered 35 hr before OPU or IUI. The clinical pregnancy rate was compared between the IUI and IVF groups. Data analysis was based on the number of cycles. The p≤0.05 was considered significant.
Results: The clinical pregnancy rate per OPU in the IVF group was higher than the one in IUI group (20.6% vs. 10.1%), and the difference was significant (p<0.01). The pregnancy rate for natural cycle IVF calculated per fresh ET was 36.8%. The miscarriage rate did not significantly differ between the IVF (4.1%) and IUI (8.0%) groups.
Conclusion: Fresh ET in natural cycle IVF provides a higher implantation rate than IUI.

Background: Oocyte donation has facilitated couples to achieve pregnancy in conditions like diminished ovarian reserve, premature ovarian failure, and inheritable disorders. However, it is unclear whether pregnancy complications are due to oocyte donation per se or due to confounding factors such as maternal age or the allogenic fetus. In this retrospective comparative cohort, an attempt was made to evaluate and compare multiple obstetric and perinatal outcomes.
Methods: The present study comprised all women in the age range of 20-45 years who conceived from oocyte donation (n=102) between 1/12/2011 to 30/09/2017. Control group consisted of spontaneous conception cases (n=306) in ratio of 1:3 with no previous medical or surgery comorbidity. Obstetric and perinatal outcomes were compared between two groups.
Results: Mean maternal age was significantly higher in the donor oocyte IVF group (group 1; 35.13 years) as compared to spontaneous conception group (group 2; 31.75 years). Parity between the two groups was comparable. Pregnancy induced hypertension (PIH) was seen in 33.33% of cases in group 1 as compared to 7.18% in group 2. Moreover, gestational diabetes mellitus was seen in 34.31% of cases in group 1 as compared to 9.47% in group 2 (p=0.001). By the same token, there was significant difference in perinatal outcomes between the two groups.
Conclusion: Oocyte donation should be treated as an independent risk factor for miscarriage, hypertensive disorder, and gestational diabetes mellitus in pregnancy.

Background: Growth of Mycoplasma in genital tract can cause problems such as infertility, pelvic inflammatory disease (PID), and preterm labor. This study was designed to evaluate the role of these bacteria in preterm labor among individuals in Gorgan city which is located in north of Iran.
Methods: The study included 100 women with complaints of pain in preterm labor before 37 weeks of pregnancy (case group) and 100 women with term labor (control group) who were referred to Shahid Sayyad Shirazi Teaching Hospital in Gorgan city, north of Iran. Vaginal swabs, collected from all of these women, were evaluated for genital Mycoplasma sp. by molecular method using specific primers with polymerization chain reaction (PCR). The comparison of results was done by conducting X2 and p<0.05 was considered significant.
Results: Genital Mycoplasma was detected in 78 cases (39%) of 200 vaginal samples. Genital Mycoplasma colonization rates in the preterm and term samples were 60% and 18%, respectively, with relative risk of 2.05 (1.78-2.37) (p=0.001). The proportion of Ureaplasma parvum (44% and 15%), Ureaplasma urealyticum (11%, 3%), and Mycoplasma homins (5%, 0%) was significantly higher in women with preterm birth (PTB) than term labor. No cases of Mycoplasma genitalum were detected in this study.
Conclusion: There is a significant relationship between presence of genital Mycoplasma in vaginal secretion and the risk of preterm labor.

Background: The COVID-19 pandemic has been shown to impact the lifestyle of couples of reproductive age and, in particular, their desire for parenthood. The purpose of this study was to carry out an evaluation on the potential changes of desire for parenthood among infertile couples waiting for assisted reproduction during the pandemic.
Methods: In this multicenter cross-sectional study, the quality of sexual life in Italian infertile couples was assessed and their well-being was evaluated before the pandemic and during the quarantine. All couples were asked to fill out a questionnaire, in which their desire for parenthood, sexual life, and well-being were investigated.
Results: Out of 1650 cases, 300 patients were finally enrolled. COVID-19 negatively impacted the well-being of individuals, leading to significantly reduced scores of happiness, feeling energetic, and interest in life (p<0.05). Although most couples had prolonged infertility, a small number of cases (4.0%) achieved a spontaneous natural pregnancy during the lockdown, probably due to more intimacy and longer time spent together. However, major concerns about the consequential effects of the virus on pregnancy and the risk of contagion in the hospital led a small number of infertile couples (5.0%) to decide to postpone their parenting project.
Conclusion: The COVID-19 pandemic may have created a further negative impact on couples, reducing their desire for parenthood. This attitude could result in a decrease in births in the near future.
