Research on Rumor Spreading Model with Time Delay and Control Effect
Authors: Yao Hongxing , Zou Yushi 
Published: September 2019

Abstract
Information flow retains a critical role in decision making among investors. In this paper, we employ a diffusion model based on epidemiology theory to study the rumor spreading process within investors. The paper introduce the feedback mechanism of classical control theory into the model, which helps to reflect the interaction between rumor spreaders and information supervision. Further we apply a time delay factor to give investors access to transparent information and change their behavior. Subsequently, the stability of the rumor disappearance equilibrium and the rumor existence equilibrium are analyzed and the condition for the system undergoes a Hopf-bifurcation is given. The mathematical arguments are subjected to numerical simulations to present the ideal case scenarios. The results suggest that, increase the general strength of information supervision and the proportion coefficient associated with the infected population in the short-term delay are conducive to better control.
Teaching Systems Theory/Thinking/Behavior: Systemic Behavior Instead of One-Sidedness: Making Bridges Among Specialists
Authors: Mulej Matjaž , Ženko Zdenka , Jakulin Tadeja Jere 
Published: September 2019

Abstract
In the current real life, systems theory is an abstract background of systems thinking, which is a part of systemic behavior. The systemic behavior is the alternative to the currently prevailing one-sidedness that puts all of humankind in danger of self-destruction due to the crucial over-sights (all the way to world wars) that unavoidably result from the current over-specialization (along with crucial, but partial insights), if the specialists fail to practice creative interdisciplinary cooperation. This contribution is a next phase of research after the contributions by Matjaz̆ Mulej, Zdenka Z̆enko and Viktor Z̆akelj (2017) and by Matjaz̆ Mulej, et al. (2013). Although the abstract background and thinking that the systemic behavior applies, are very necessary, theory and thinking are no longer enough for systems science to be a relevant science and practice helping humankind find the way out from the current blind alley and survive as a healthy civilization with a healthy social and natural environment. The suggestion in this contribution therefore reads: Let us systems and cybernetics scientists make/enable the transition to systemic behavior, which applies all the many theories, which are components in the background of systemic behavior in practice, next to each other and/or in synergy. Analysis, i.e., studying per isolated parts is too overlooking and one-sided to be enough. So is teaching on a single one out of several systems theories. Reality is too complex. Teaching is a part of this necessary effort, which must lead to a global peace and survival of humankind of today instead of the current hating the human descendants.

Abstract
Introduction The application of PET/CT directly improved treatment choice and management in 25% of non-small cell lung cancer patients and 29% of small cell lung cancer patients. However, the long-term outcome of altering the management of these patients remains unclear. The aim of this study was to compare the 5-year overall survival rates of two groups of clinical stage I lung cancer patients: those who received PET/CT and those who did not.Methods Data were obtained from the Taiwan Society of Cancer Registry. There were 6,587 clinical stage I lung cancer patients analyzed between 2009 and 2014 in this retrospective study. We performed propensity matching to reduce the bias; it resulted in both groups having 2,649 patients. We measured the 1, 3, and 5-year survival rates of all clinical stage I lung cancer patients and the survival rates of pathological I, II and III lung cancer patients and compared the survival rates between clinical stage I lung cancer patients with PET/CT scans and patients without PET/CT scans.Results The 1, 3, and 5-year survival rates of all clinical stage I lung cancer patients are 97.2%, 88.2% and 79.0%, respectively. The 1, 3, and 5-year survival rates are 97.0%, 88.2% and 79.8% in the PET/CT group and 97.5%, 88.1% and 78.2% in the no PET/CT group; there was no statistical difference (p= 0.6528).Conclusion Although stage I lung cancer patients who received PET/CT had their management strategies modified and avoided any unnecessary thoracotomies, our data showed that there was no 5-year survival benefit for these patients.

Abstract
Background : To investigate the influence of body mass index (BMI) on the short-term and long-term outcome s including disease free survival (DFS) and overall survival (OS) rate in patients with liver carcinoma who underwent laparoscopic hepatectomy (LH) as primary treatment.Methods: Data were collected from 137 patients with liver carcinoma who underwent attempted LH between August 2003 and April 2014. Patients were classified into three groups depending on their BMI according to the WHO’s definition of obesity for Asia-Pacific region: underweight (BMI< 18.5kg/ m 2 , Group1), normal (18.5≤BMI< 23kg/m 2, Group2), overweight (BMI≥ 23kg/m 2, Group3) respectively. Short-term and long-term outcome s including overall survival (OS) and disease free survival (DFS) were compared across the BMI categories.Results: Of the 137 patients, 14 were underweight, 65 were normal weight, and 58 were overweight. The overall conversion rate of 137 patients was 20.44 %. Conversion rate in the three groups was 14.29%, 21.54% and 20.69 % (P=0.8284). The median follow-up duration was 26 months , 30 months , and 28 months, respectively. The mean postoperative hospital stay in the three groups were comparable (10.85±4.04, 11.57±5.56 , and 10.88±5.70, P=0.76). The complications rate was much higher in Group 1 (42.85%) than that in Group 2 and Group 3 (20.08% and 17.2%, P=0.048). Underweight patients were more likely to develop grade III or higher postoperative complications ( Clavien-Dindo classification ) as compared to normal and overweight patients (P=0.042). Overweight patients had a longer 3- and 5-years DFS (41.4%, 36.2%) than those for underweight (21.4%, 14.3%) and normal weight (28.1%, 21.9%) patients (P=0.048, and 0.025). Overweight patients had a longer 5-years OS (44.8%) than those for underweight (28.6%) and normal weight (28.0%) patients (P=0.043).Conclusions : Being underweight was associated with an increased perioperative complication and being overweight has a better 3-, 5-years DFS and 5-years OS than those in under and normal weight patients with liver carcinoma who underwent LH.

Digital crisis in enterprise innovation
Authors: Dneprovskaya N. V. 
Published: September 2019

The purpose of the research is to reveal the phenomenon of “digital crisis” in the context of the development of the digital economy, to identify its impact and consequences for the innovative activity of the enterprise. Commitment to the development of the digital economy suggests that the gathering and processing of the increasing volume of digital data will increase the effectiveness of various types of economic activities. However, throughout the scientific and technological progress, the amount of accumulated information has increased at a pace ahead of the intellectual and computational capabilities of the society to process them. Statistical studies show the accumulated contradiction between the growing level of digitalization of Russian society and the stagnation of innovative activity of Russian enterprises.Materials and methods of research include the study of the ITindustry as a provider of resources for the development of innovations in the digital society. The analytical reports of consulting ITcompanies (IDC, McKinsey), the results of studies of the accumulated experience of its implementation in the activities of enterprises, the official statistics made up the factual basis of the research. The methodological basis of the study includes approaches to assessing the effectiveness of access to digital data, assessing the effectiveness of their use for solving economic problems.The results of research show the presence of the digital crisis, which is expressed in the inability of the IT-infrastructure to provide enterprises with effective access to digital data in the course of their innovation. At the same time, the volume of digital data is growing exponentially with the spread of the Internet of things and the increasing frequency of citizens’ interactions with digital services and platforms. The digital crisis makes it impossible for enterprises to extract knowledge from the data stream to develop innovation.Conclusion. While Russian enterprises are experiencing the impact of the digital crisis, which makes it difficult to develop innovations using a combination of IT and digital data, the Russian and global market is filled with foreign digital goods and services. The achievements of digitalization of Russian society become the basis for the development and dissemination of foreign innovations. Overcoming the digital crisis depends on factors either the external and internal environment of enterprises. The competence of the enterprise itself is the improvement of its organizational structure, business model and human resources. The external environment should create favorable conditions for enterprises’ access to innovation resources.

Published: September 2019

The purpose of the study is to improve the quality indicators of adaptive multichannel detection-resolution-measurement parameters of stochastic signals under parametric a prior uncertainty.Materials and methods. The methodology for the synthesis of signal detectors of various structures, taking into account various factors, is used to achieve the goal. This makes it possible to exclude from the expression for estimating the signal power the terms due to “colored” internal noises and an uncorrelated background. The tools of correlation analysis, adaptive Bayes approach, criterion of generalized likelihood ratio, methods of calculating its logarithm are also used. Results. In this paper, the problems of synthesis of adaptive multichannel detection-resolution algorithms for stochastic signals of various structures under the influence of intense noise interference are considered. An integral element of the detection task is a joint assessment of the intensity of the useful signal and the correlation matrix of interference. This problem is effectively solved for highintensity signals, and the nonstationarity of the internal noise of the receiving uncorrelated background of the interfering signals is not taken into account. A multi-channel receiving system consisting of a number of independent spatially separated elements that form a linear antenna array is considered. The width of the spectrum of the received signals should be considered sufficiently narrow, so that the delay of the signals at the antenna aperture can be neglected. This provision can significantly improve the performance of detection and resolution of stochastic signals in the background of noise interference. Based on the analysis of a finite discrete sample of complex amplitudes of received oscillations, a detection problem was solved, which is formulated as a problem of checking statistical hypotheses regarding distribution parameters. The detection algorithm is reduced to a comparison with the likelihood ratio threshold, and the threshold level value is determined by the selected optimality criterion and for the Neumann-Pearson criterion remains dependent on the power of interfering oscillations.Conclusion. The presented detector possesses higher characteristics of detection and resolution of stochastic signals in comparison with the known ones. It can be shown that an important property of the obtained statistics is the stabilization of the probability of false detection. This is achieved by normalizing the noise power at the output of the adaptation device. In addition, the resulting algorithm is invariant to the form used for its calculation of the correlation matrix of interference. If we take into account that an uncorrelated background will be added to the internal noise power, with a large number of noise jammers, a significant improvement in the detection performance has been achieved.

Pahlawan Perang Dunia II Winston Churchill suatu ketika pernah berkata, “Sejarah dibuat oleh para pemenang”. Jika kita membaca dan mencermati sejarah dunia dari masa ke masa, kata-kata tersebut barangkali ada benarnya. Para penakluk Spanyol (conquistadores) mulai dari Christopher Columbus, Fransisco Pizzaro, sampai Hernan Cortez mengarang cerita bahwa orang-orang Indian Amerika adalah masyarakat barbar (uncivilized) sehingga menjustifikasi penaklukan oleh masyarakat Eropa yang ‘tercerahkan’ (civilized). Pasca Perang Dunia II Sekutu sebagai pihak yang menang punya otoritas penuh untuk mereka-ulang rancang-bangun tatanan internasional. Dalam konteks ini, pendukung setia hegemoni Amerika John Ikenberry mengatakan dalam bukunya berjudul ‘After Victory: Institutions, Strategic Restraint, and the Rebuilding of Order After Major Wars’ bahwa munculnya institusi-institusi global semacam GATT yang kemudian berubah menjadi WTO, IMF, Bank Dunia, bahkan PBB tak luput dari upaya Amerika Serikat untuk merekonstruksi dunia menurut sudut pandangnya.Jika benar dunia dibentuk oleh kekuatan besar, lantas bagaimana peran negara-negara lain, lebih khusus negara-negara berkembang? Kita semua mahfum bahwa negara-negara berkembang dulunya adalah negara terjajah. Negara-negara ini rata-rata baru lahir dalam kurun waktu pasca Perang Dunia II sampai dengan dekade 1960-an. Dari segi geografis, negara-negara ini menempati tiga kawasan besar dunia yakni Asia, Afrika, dan Amerika Latin. Ketiga kawasan itu secara ekonomi dulunya dianggap sebagai kawasan marjinal, atau periphery menurut istilah penganut teori dependensia klasik. Kombinasi antara faktor politik sebagai negara terjajah dan faktor ekonomi sebagai negara ‘kelas dua’ membuat negara-negara berkembang tidak memiliki andil besar dalam arsitektur tatanan internasional.Tetapi apakah benar demikian?

Sugarcane mosaic virus (SCMV, genus Potyvirus, family Potyviridae) is a prominent pathogen of sugarcane (Saccharum sp. hybrids). It can cause losses in susceptible varieties, in crop as well as sugar production, economically. Although it has been studied in major sugar-producing countries, research on the definement of SCMV from Indonesian isolates based on molecular study has been very limited. This study aimed to obtain a proper recombinant antigens emanating from coat protein of SCMV from Indonesian isolate in order to produce polyclonal antibodies that cann be used for immunodiagnosis assays in a subsequent study. A gene-encoding coat protein of SCMV (CP-SCMV) was amplified using RT-PCR and cloned into vector pJET1.2. The cDNA was inserted into 6X His-tag expression plasmid of pET28a(+) and over-expressed in Escherichia coli BL21(DE3) to produce a recombinant protein. The highest expression was found in 0.1M IPTG induction media for 5 h at 37oC. SDS-PAGE analysis clarified that the recombinant CP-SCMV remained as an insoluble fraction. Purifications was carried out by the affinity Ni-NTA resin, followed by electroelution to obtain a highly purified protein. To meet the quality requirements of a proper antigen, the highly purified protein was concentrated. A molecular weight of the rCP-SCMV (approximately 40 kDa) was clearly observed by 10% SDS-PAGE at the concentration of 16.184 mg/mL.
