RETRACTED: Prediction of energy consumption of numerical control machine tools and analysis of key energy‐saving technologies
Authors: Qiang Han , Ikbal Mohammad Asif , Khanna Shaweta
Published: February 2021

The objective of this study is to ensure the sustainable development of traditional machinery manufacturing industry under limited conditions of non‐renewable energy, and reduce the environmental pollution caused by high energy consumption of machine tools. Here the energy consumption of numerical control machine tools is analysed, and the relevant energy‐saving model is established. The energy consumption system of the numerical control machinery tools, including the cutting parameters, is classified. The relevant energy consumption prediction model is built to evaluate the influence of different cutting parameters, feed per tooth, and the back cutting depth on the energy consumption of numerical control machine tools. The results show that classifying the energy consumption system of numerical control machine tools can effectively predict the energy consumption of machine tools, which provides theoretical support for the subsequent energy‐saving experiments. Larger cutting parameters will increase the energy consumption of numerical control machine tools, improve the energy efficiency of machine tools at the same time. Thus, reducing the feed per tooth and the back cutting depth can effectively decrease its energy consumption. The results of this study provide data support and guidance for the energy‐saving experiments and practical applications of numerical control machine tools.
Collaborative transmit resource scheduling and waveform selection for target tracking in multistatic radar system
Authors: Wang Yijie , Shi Chenguang , Wang Fei , Zhou Jianjiang
Published: February 2021

This paper proposes a collaborative transmit resource scheduling and waveform selection (CTRSWS) strategy for target tracking in multistatic radar system which consists of one transmitter and an arbitrary number of receivers. The main mechanism of the proposed CTRSWS strategy is to exploit the optimisation technique to jointly optimise the illumination power, dwell time, waveform bandwidth, and pulse length under the constraints of several resource budgets and the predefined waveform library, aiming at improving the low probability of intercept (LPI) performance and target tracking accuracy of multistatic radar system simultaneously. The analytical expressions for the probability of intercept and the trace of the predicted error covariance matrix corresponding to the target state estimation are derived and adopted to evaluate the LPI performance and target tracking accuracy, respectively. Subsequently, the resulting non‐convex and non‐linear optimisation problem is resolved by an efficient and fast four‐stage solution methodology. Several numerical results are provided to verify the effectiveness and superiority of the proposed CTRSWS scheme in terms of the achievable LPI performance and target tracking accuracy of multistatic radar system.
Underwater source localization in the presence of strong interference
Authors: Li Haipeng , Jakobsson Andreas , Sun Dajun , Zheng Cuie
Published: February 2021

The underwater localization of a broadband target in the presence of strong interference and noise has been widely investigated. A novel clutter suppression approach based on oblique projections is proposed, exploiting the prior information of the expected target response. The method uses a generalised likelihood ratio formulation to select the oblique projection best matching the measured data. The performance of the proposed method is verified through numerical examples and measured sonar data. The results indicate that the method provides good performance for time difference of arrival estimation and target localization under low signal to clutter ratio as compared to existing methods.

Published: February 2021

The clinicopathological implication and prospective molecular mechanisms of miRNA‐145‐5p in the metastasis of prostate cancer (PCa) stand unclear. Herein, it is found that miRNA‐145‐5p expression was remarkably reduced in 131 cases of metastatic PCa than 1371 cases of localised ones, as the standardised mean differences (SMD) was −1.26 and the area under the curve (AUC) was 0.86, based on miRNA‐chip and miRNA‐sequencing datasets. The potential targets of miRNA‐145‐5p in metastatic PCa (n = 414) was achieved from the intersection of miRNA‐145‐5p transfected metastatic PCa cell line data, differential expression of metastatic PCa upregulated genes and online prediction databases. TOP2A was screened as one of the target hub genes by PPI network analysis, which was adversely related to miRNA‐145‐5p expression in both metastatic PCa (r = −0.504) and primary PCa (r = −0.281). Gene‐chip and RNA‐sequencing datasets, as well as IHC performed on clinical PCa samples, showed consistent upregulated expression of TOP2A mRNA and protein in PCa compared with non‐PCa. The expression of TOP2A mRNA was also significantly higher in metastatic than localised PCa with the SMD being 1.72 and the AUC of sROC being 0.91. In summary, miRNA‐145‐5p may participate in PCa metastasis by binding TOP2A and be useful as a biomarker for the detection of metastatic PCa.
Spatially resolved properties of galaxies with a kinematically distinct core
Authors: Omori Kiyoaki Christopher , Takeuchi Tsutomu T.
Published: February 2021

Aims. Interacting galaxies show unique irregularities in their kinematic structures. By investigating the spatially resolved kinematics and stellar population properties of galaxies that demonstrate irregularities, we can paint a detailed picture of the formation and evolutionary processes that took place during their lifetimes.

Methods. In this work, we focused on galaxies with a specific kinematic irregularity: a kinematically distinct stellar core (KDC). In particular, we considered counter-rotating galaxies in which the core and main body of are rotating in opposite directions. We visually identified 11 MaNGA galaxies with a KDC from their stellar kinematics, and we investigated their spatially resolved stellar and gaseous kinematic properties, namely the two-dimensional stellar and gaseous velocity and velocity-dispersion (σ) maps. Additionally, we examined the stellar population properties, as well as spatially resolved recent star formation histories, using the Dn4000 and Hδ gradients.

Results. The galaxies display multiple off-centred symmetrical peaks in the stellar σ maps. The gaseous velocity and σ maps display regular properties. The stellar population properties and their respective gradients show differing properties depending on the results of the spatially resolved emission line diagnostics of the galaxies, with some but not all galaxies showing inside-out quenching. The star formation histories also largely differ based on the spatially resolved emission line diagnostics, but most galaxies show indications of recent star formation either in their outskirts or core.

Conclusions. We find a distinct difference in kinematic and stellar population properties in galaxies with a counter-rotating stellar core, which depends on its classification using spatially resolved emission line diagnostics.

Authors: Xu Yang
Published: February 2021

This paper selects the panel data of 260 listed companies in China’s GEM from 2013 to 2017, and uses a fixed effect regression model to verify and analyze the overall impact of asset financialization of small and medium-sized entrepreneurial companies on R&D investment. The results show that the two are positively related overall. In addition, from the perspective of the shareholding structure, the threshold effect model is used to explore how the direction and extent of the effect of asset financialization on corporate R&D investment dynamically change. It is concluded that these will have a nonlinear relationship with the change in the shareholding structure. Only by optimizing the shareholding structure and adjusting the shareholding ratios of major shareholders and management to an appropriate range can the optimal promotion effect of asset financialization on enterprise R&D investment be achieved, and the harmonious development of the relationship between finance and real economy can be promoted.
Economic consequences of resource trade-offs for special disaster-blessed industries: the case of COVID-19 pandemic Economic consequences of COVID-19 pandemic
Authors: Sajid Muhammad Jawad
Published: February 2021

The new COVID-19 pandemic has spread to almost every nation in the world. Most of the available literature on the economic effects of COVID-19 focuses mainly on the recessionary effects of COVID-19 on different industries and aggregate economies. However, some industries, such as masks (surgical and N95, etc.), ventilators and miscellaneous medical services, benefit economically from the current COVID-19 disaster. More and more resources have been diverted to these industries due to the increased demand of these special industries. Excessive demand from these special industries will eventually return to normal or, under special conditions, fall below their normal (usual) demand once the pandemic has ended. Which, in turn, will not only affect these special industries, but can also have an impact on the recovery of aggregate economies around the globe. The study presents a comprehensive model for the different phases of the short-term lifecycle of these special industries. Presentation of the working and economic backlash resulting from the eventual decline in demand of these industries may encourage world economic policymakers to look beyond the current disastrous situation and to devise the necessary monetary and fiscal policies for the future COVID-19 free era. Otherwise, it will be difficult for the economies recovering from COVID-19 pandemic to move back to normal functioning, because the additional resources (such as labor and capital) allocated to these special industries may be idle for some time, which may increase the burden and drag the recovering economies of the COVID-19 pandemic into a deeper recession even when the pandemic is over.

Authors: Lyu Rui , Liu Zhiqiang
Published: February 2021

With Hexi Corridor as the study case, this study established an evaluation index system for the development of the industrial parks and industrial clusters, and used the coupling coordination model and exploratory spatial data analysis method (ESDA) to explore the evolution and spatial correlation of the coupling coordination between the industrial park and industrial clusters in Hexi Corridor from 2005 to 2017. It is found that from 2005 to 2017, the industrial parks and industrial clusters has shown closer correlations; despite the high level of coordination, the degree of coupling remains low; the Hexi Corridor has not yet developed a growth engine for the coordinated development of the industrial parks and the clusters, and there is no county-level industrial entities that have strong stimulating power. Given the requirements of the current industrial agglomeration model for regional innovation capabilities, this study proposes suggestions for coordinated development of industrial parks and industrial clusters in Hexi Corridor.
Study on the Difficulties of Building a Service-oriented Government——A Case Study on the Satisfaction of Public Service Quality of Guizhou Province in 2019
Authors: Liu Siyue
Published: February 2021

This paper explores the difficulties of building a service-oriented government by taking the evaluation results of public service satisfaction of Guizhou province in 2019 as an example. This paper finds that building a service-oriented government is the process of improving the quality of public service in an all-round way. With the steady improvement of the public service quality in China, the public’s expectation of the public service quality has been improved by changing from the original “yes or no” to the current “good or not”. In order to speed up the construction of service-oriented government, government departments should pay attention to the change of public demand and take the comfort, richness and transparency of public service as the key points of quality improvement.

Research on the Fairness of MPACC Selection Based on Examiner Heterogeneity
Authors: Wang Yan , He Zhuqian , Zheng Jingjie
Published: February 2021

The selection of MPACC (Master of Professional Accountant) is a key step in the training of senior accounting personnel. This paper examines the relationship between examiner heterogeneity and MPACC second test scores. We try to clarify the reason for the unfair phenomenon because of the heterogeneity of examiners in MPACC second test results and seek ways to solve this problem. The study found that the MPACC second test results are unfair. This unfairness is caused by the heterogeneity of the examiner. However, standardized algorithms balance the differences in MPACC examiner heterogeneity. The regression model was constructed by using the MPACC second test scores before and after standardization, which verified the existence of examiner heterogeneity and the effect of the standardized algorithm on the examiner heterogeneity. This article is based on the differences of MPACC second test scores due to examiner’s heterogeneity. We propose the application of standardized algorithm, which will play an important role in improving the quality of MPACC enrollment and promoting the training of senior accounting personnel.

The Misunderstanding of Business Management Innovation in the Digital Economy Era Excess Merger and Corporate Innovation
Authors: Li Shuyan
Published: February 2021

With the development of digital economy and technological innovation, many companies transform their model to improve market competitiveness. Some companies choose to achieve digital transformation through their own exploration, but more companies adapt to the change through large-scale mergers and acquisitions of technologically innovative companies, even cross-border mergers and acquisitions. Some companies want to integrate high-quality resources at the expense of excessive mergers and acquisitions, and eventually form the excess goodwill. However, whether such excess mergers and acquisitions can really promote corporate innovation still needs to be further explored. Through empirical research, this paper finds that excessive mergers and acquisitions do inhibit the innovation and development of enterprises, and then reveals the mechanism of action. This article reveals a misunderstanding of enterprise innovation and development, that is, the harm of excessive mergers and acquisitions to adapt to changes. It provides a new perspective for enterprises pursuing innovation, which is conducive to the management and development of innovative activities.

COVID-19 und Plastische Chirurgie – Schönheitschirurgie oder wichtiger Bestandteil der medizinischen Versorgung?
Authors: Popp Daniel , Smolle Christian , Nischwitz Sebastian P. , Sawetz Isabelle , Schaunig Caroline , Winter Raimund , Spendel Stephan , Kamolz Lars-Peter
Published: February 2021

Einleitung Im Frühjahr 2020 machte die COVID-19-Pandemie weitreichende Veränderungen und Maßnahmen in bisher nie dagewesenem Ausmaß notwendig. Diese Maßnahmen zielten einerseits darauf ab die Ausbreitung der Virusinfektion einzudämmen, und andererseits die landesweite Krankenversorgung weiterhin zu gewährleisten, insbesondere um im Falle einer größeren Anzahl an mit COVID-19 infizierten Patienten ausreichend Intensivkapazitäten zur Verfügung zu haben. In Bezug auf operative Fächer bedeutete dies das temporäre Aussetzen des Elektivprogramms auf unbestimmte Zeit. Ziel dieser Studie war es die Auswirkung dieser Maßnahmen auf das Behandlungsspektrum eines plastisch-chirurgischen Zentrums zu evaluieren.

Methode Die Operationszahlen der klinischen Abteilung für Plastische, Ästhetische und Rekonstruktive Chirurgie der medizinischen Universität Graz während des sog. Lockdowns von 16.3.2020 bis 26.4.2020 (6 Wochen) sowie 2 Wochen davor wurden retrospektiv erhoben. Die Daten wurden zum korrespondierende Vorjahreszeitraum verglichen. Untersucht wurden u. a. Operationsspektrum, Dringlichkeit, Indikation und Komplikationsraten.

Ergebnisse Durch den Wegfall des Elektivprogramms kam es während des Lockdowns im Jahresvergleich zu einem signifikanten Rückgang der OP-Zahlen um 57,5 % (2019: 353, 2020 150 Fälle). Während des Lockdowns wurden im Jahresvergleich signifikant mehr Notfall- und Akuteingriffe durchgeführt (2019: 41, 2020: 58 Fälle, p < 0,001). Außerdem wurde eine signifikante Häufung von Selbstverletzungen bzw. Suizidversuchen beobachtet (2019: 0, 2020: 16 Fälle, p > 0,001). Hinsichtlich Privat- und Arbeitsunfällen gab es keine signifikanten Unterschiede. Es zeigte sich auch kein signifikanter Unterschied bezüglich der Komplikationsrate (2019: 6,8, 2020: 10 %, p = 0,219).

Zusammenfassung Ein signifikanter Anteil plastisch-chirurgischer Operationen an einem Universitätsklinikum mit überregionalem Versorgungsauftrag besteht aus Notfalloperationen, akuten und dringenden medizinisch notwendigen Operationen. Während des Lockdowns wurden Operationen ohne signifikanten Anstieg der Komplikationsrate durchgeführt. Trotz sämtlicher Herausforderungen während der Pandemie konnte eine qualitativ konstante Patientenversorgung auf höchstem Niveau gewährleistet werden. Um die während des Lockdowns angehäuften weniger dringenden, jedoch ebenso wichtigen Fälle zeitgerecht und in entsprechend hoher Qualität abzuarbeiten, wird eine Erweiterung der Operationskapazitäten mit Steigerung der Bettenanzahl und der Ambulanzkapazität notwendig sein. Die vorliegenden Ergebnisse zeigen, wie wichtig die Plastische Chirurgie für die medizinische Versorgung insbesondere in Krisenzeiten ist.

Background The management of proximal humeral fracture (PHF) is not only complex but ever changing. Published epidemiological data are often dated and do not factor in demographic
changes or the latest developments in implant material and surgical techniques.

Aims The primary aim of this study was to evaluate changes in the epidemiology and actual treatment of PHF at a level-1 trauma centre, with a special focus on shoulder surgery.

Hypotheses 1. Between 2009 to 2012 and 2014 to 2017, an increase in complex PHF entities can be observed. 2. In correlation with fracture complexity, an increasing number of
comorbidities, especially osteoporosis, can be observed.

Methods Between 2014 and 2017, a total of 589 patients (73% female; mean age: 68.96 ± 14.9 years) with 593 PHFs were treated. Patient records and imaging (XRs and CTs) of all
patients were analysed. Fractures with ad latus displacement of a maximum of 0,5 cm and/or humeral head angulation of less than 20° were classified as non-displaced. Patients with displaced
fractures were included in the analysis of the therapeutic algorithm. These results were compared to those of a cohort 2009 to 2012 (566 patients, 569 PHFs), which used the same inclusion
criteria.

Results The two cohorts showed comparable patient numbers, as well as gender and age distributions. Between 2009 to 2012 and 2014 to 2017, a decrease in 2-part fractures (13.9 to
8.6%) and a simultaneous increase in 4-part fractures (20.4 to 30%), and thus fracture complexity was observed. Further decreases were observed in conservative therapy (27.8 to 20.6%), nail
osteosynthesis (10.7 to 2.7%) and anatomic shoulder arthroplasty (5,4 to 1%). Furthermore, there was an increase in the use of locking plate osteosynthesis (43.2 to 56.7%) and reverse
shoulder arthroplasty (9 to 18.4%). The general trend shows an increase in surgical therapy between the years (72.2 to 79.4%), as well as an increase in osteoporosis incidence (13 to 20.6%).
The greatest numbers of comorbidities were found in 3- and 4-part fractures.

Conclusion There is an increase in both the complexity of fractures and the number of surgically treated fractures between 2009 and 2012. Furthermore, an increase in osteoporosis
numbers can be observed. New implants (PEEK, fenestrated screws for cement augmentation) and new surgical techniques (double plating osteosynthesis) were used as a result of increasing
fracture complexity. Moreover, reverse total shoulder arthroplasty was used more commonly.

Objective The burden of dengue fever (DF) is increasing rapidly worldwide. Several atypical manifestations of DF are being increasingly reported but there are no clear guidelines on their definition and management. Their timely detection and appropriate management might improve outcomes. We describe here our experience in managing atypical manifestations of DF in children and their outcomes in a teaching hospital in South India.

Methods A retrospective chart review of children (1 month–18 years) hospitalized, between August 2017 and March 2018 with a diagnosis of DF (NS1 antigen or immunoglobulin M antibodies positivity), was done. The clinical details of the atypical manifestations are described.

Results During the study period, 925 children were hospitalized with DF, of which 94 (10.16%) had severe dengue and 2 (0.21%) died. Among the 925 children, 7 (0.75%) had cardiac, 5 (0.54%) had neurological, 5 (0.54%) had hepatic, and 31 (3.3%) had immunological (infection-associated immune dysregulation) manifestations.

Conclusion Most children with atypical manifestations of DF recover with supportive management. There is a need for a clear definition of atypical manifestations so that large prospective multicenter studies on incidence, optimum management, and outcomes can be done.
Medical Management in Focal versus Generalized Epilepsy

About 70% of children with new-onset epilepsy have the potential to become seizure-free on antiepileptic drug (AED) monotherapy with appropriately selected first-line medication. In ideal world, physician is expected to achieve best possible seizure control without impacting the quality of life. There is rapid increase in number of AEDs available over last couple of decades. Although not necessarily all of them are superior to old generation drugs in terms of seizure control, certainly there is change in landscape from perspective of tolerability and side-effect profile. Physicians must therefore be familiar with safety, tolerability, therapeutic effects, synergistic combinations as well as AEDs to avoid in specific circumstances. The article attempts to give general overview of available AEDs under broad umbrella of effectiveness against focal and generalized seizures as well as drugs with “broad spectrum.” The emergence of newer AEDs with broad spectrum and favorable side-effect profile is welcome. However, the future lies in better understanding of underlying diverse pathophysiology of clinical symptom “epilepsy” and developing new compounds acting on molecular targets as well as individualizing therapy. Technological advances in molecular genetics research are bringing precision medicine to the fore.
Ramsay Hunt's Syndrome in Pediatric Age

The Ramsay Hunt's syndrome (RHS), caused by the reactivation of the varicella-zoster virus (VZV), is an infrequent cause of peripheral facial palsy in the pediatric patients. A 16-year-old adolescent boy presented with headache, right earache, and signs of lower motor neuron type facial palsy. He was medicated with deflazacort. Four days later, he developed blurry vision in the right eye, gait imbalance, and vesicular lesions in the right ear with decreased ipsilateral hearing acuity. A diagnosis of RHS was considered. Cerebrospinal fluid (CSF) analysis showed pleocytosis, as well as VZV DNA. Magnetic resonance imaging of the brain identified abnormal uptake of gadolinium contrast in the right seventh cranial nerve, reinforcing the diagnosis. The patient was treated with acyclovir (14 days) and prednisone, with progressive clinical improvement. We emphasize the importance of recognizing this syndrome in patients with facial palsy, since the early antiviral treatment significantly improves the prognosis.
