Comparison of Rapid Antibody Test and Thorax Computed Tomography Results in Patients who Underwent RT-PCR with the Pre-Diagnosis of COVID-19
Authors: Kızıloglu İlker , Şener Aslı , Siliv Neslihan
Published: February 2021

Introduction: In this study, it is planned to compare the RT-PCR test,
which is the gold standard in the diagnosis of COVID-19, with Thorax
computed tomography (CT) and rapid antibody test results. Methods:
Patients who were admitted to the emergency service of İzmir Çiğli
Training and Research Hospital between 01.04.2020 and 31.05.2020 and who
were suspected of having COVID-19 infection were included in the study.
The medical records of the patients were retrospectively analyzed
through the hospital data processing database. Age, gender,
hospitalization, status of home quarantine, real-time reverse
transcription-polymerase chain reaction (RT-PCR), thorax CT and rapid
antibody test results of the patients were examined. The relationship
between RT-PCR, thorax CT and rapid antibody test results were compared
statistically. Results: A total of 181 patients, 115 (63.5%) male and
66 (36.5%) female, with an average age of 56.4 ± 18.06 years were
included in the study. The nasopharyngeal swab PCR result obtained at
the first admission of the patients to the emergency department was
positive in 71 (39.2%) patients. Thorax CT was performed in 173
(95.6%) patients who applied to the emergency department, and 112
(64.7%) of them had findings that could be compatible with COVID-19.
According to the thorax CT findings in patients, sensitivity,
specificity, positive predictive value (PPV) and negative predictive
value (NPV) for detecting COVID-19 infection were respectively; 76.1%,
43.1%, 48.2% and 72.1% (ĸ: 0.176, p <0.001). In our study,
the mortality rate for COVID-19 was found to be 2.8%. Conclusion: Rapid
antibody test and thorax CT examinations were found to have low
diagnostic value in patients who admitted to the emergency department of
our hospital and whose first RT-PCR SARS-CoV-2 test was positive.
Studies involving larger patient groups are needed for their use alone
in diagnosis and screening.
Emergency Cardiac Surgery in Patients on Oral Anticoagulants
Authors: Akhrass Rami , Gillinov A. Marc , Bakaeen Faisal , Cameron Scott , Bishop Jay , Kapadia Samir , Svensson Lars
Published: February 2021

Emergency surgery, blood transfusion, and reoperation for bleeding have
been associated with increased morbidity and mortality. Every effort is
made to optimize patients preoperatively including cessation of oral
anticoagulants in an attempt to normalize the coagulation profile. The
recent explosive use of direct oral anticoagulants (DOACs) and
antiplatelet medications has made the above more difficult.
Cardiopulmonary bypass (CPB), with its associated fibrinolysis and
platelet consumption, may exacerbate a pre-existing coagulopathy. In
addition, the underlying surgical pathology, such as endocarditis
accompanied by sepsis and disseminated intravascular coagulopathy (DIC)
or aortic dissection requiring hypothermia and circulatory arrest, can
aggravate an already challenged hematological profile. Ensuring a dry
operative field upon entry by correcting the coagulopathy is offset by
the concern of potentially hindering efforts to anticoagulate the
patient in preparation for CPB, in addition to possibly creating a
hypercoagulable state that could increase the risk of thromboembolic
events. Management is challenging and decisions are typically made on a
case-by-case basis. Surgery is delayed when possible and less invasive
percutaneous options should be considered if feasible. If surgery is
unavoidable, attention is paid to exercising meticulous techniques,
avoiding excessive hypothermia, treating coexisting issues such as
sepsis and correcting the coagulopathy with antidotes, reversal agents
and blood products, with the understanding that a normal coagulation
profile does not necessarily translate into hemostasis or the absence of
thrombosis. Proper knowledge of the mechanism of action of the oral
anticoagulants, available antidotes and their time to onset are
essential in properly treating this difficult patient population.

In this paper, we consider the chemotaxis model
u_t&=\Delta
u-\nabla\cdot(u\nabla v),&
\qquad
x\in\Omega,\,t>0,v_t&=\Delta

x\in\Omega,\,t>0,under
homogeneous Neumann boundary conditions in a bounded and convex domain
$\Om\subset
\mathbb{R}^3$ with smooth boundary, where
$\delta>0$ is a given parameter. It is
shown that for arbitrarily large initial data, this problem admits at
least one global weak solution for which there exists
$T>0$ such that the solution $(u,v,w)$ is bounded and
smooth in
$\Om\times(T,\infty)$.
Furthermore, it is asserted that such solutions approach spatially
constant equilibria in the large time limit.

Published: February 2021

Today, the matters pertaining to regional and urban development in the EU are increasingly integrated into EU development plans and strategies. The EU actively facilitates regional development by supporting the development of small and medium-sized enterprises in the regions to contribute to employment, education and social integration. The strategic goal of the National Development Plan of Latvia 2021-2027 is to promote also regional development in Latvia in order to ensure long-term balanced growth in the country. Promoting entrepreneurship in the regions is of great importance, as Latvia is still one of the countries in the European Union experiencing unbalanced regional development and having socio-economic disparities. Consequently, financial performance and financial stability play an important role in sustainable business development. Rural entrepreneurs whose business is seasonal often lack an awareness of the role of financial leverage degrees, which could lead to making wrong decisions. Performing an assessment of the degrees of financial leverage could be useful not only in a situation when experiencing a business expansion but also when a business decline occurs, which is specific to rural entrepreneurship. A hypothesis of the present research is based on the authors’ opinion that by meaningfully applying the degrees of financial leverage, it is possible to enhance the financial performance of enterprises, which is particularly important for rural entrepreneurship. The aim of the research is to define the degrees of financial leverage – the degree of operating leverage (DOL), the degree of financial leverage (DFL) and the degree of combined leverage (DCL) – as measures of financial performance of enterprises and classify the principles of measure assessment in relation to whether the indicator percentage changes used in financial leverage calculations are positive or negative. The research employed the following methods: induction – to make scientific assumptions and identify similarities based on individual elements – and deduction – to logically systematize and explain empirical data. Applying the empirical and logical construction methods, the authors analysed six different theoretically possible situations, gave six different examples, defined and classified the principles of leverage degree assessment as different (positive and negative) in relation to the indicator percentage changes used in financial leverage calculations.

Published: February 2021

Demographic transformation and increase of older people in Europe have encouraged discussions regarding how economics could help older people to grow old in a dignified way and be active in labour market. In Latvia the term older people is usually applied to pensioners. In this research the author analysed the number of pensioners in Latvia from 2012 till 2018, as well as change of pensioners’ employment level in population aged 45 and over. This research showed that 63.1 % of pensioners (45 years old and over) in Latvia were employed in 2018. Compared to 2012 the amount of employed pensioners in 2018 has increased by 10.2 %. Regression analysis between employed pensioners and average pension in Latvia from 2004 till 2018 shows a statistically significant linear interrelationship (R2 = 0,723) but the data correlation analysis shows a strong positive correlation (r = 0,850).

After the collapse of Soviet system, immediately after declaration of independence, Estonia, Latvia and Lithuania decided to initiate land reform within the framework of agrarian reform. The defined general objectives of land reform were: to establish a fairer system of property and use rights, to create conditions for intensity and productivity increasing of land use, to strengthen the rights of lessors and tenants, to grant land to those who wish to cultivate or otherwise use the land. However, the legislation and administrative systems of separate Baltic States were different, so the objectives and tasks of land reform, as well as the measures and methods for implementing the land reform, were different. The aim of the article is to compare and evaluate the land ownership reform processes in Estonia, Latvia and Lithuania, to analyse their legal security, the objectives, tasks, process and procedures of the reform, as well as the results obtained. In order to find out the situation and to make comparative judgments and conclusions, in research mainly document analysis and monographic or descriptive method haves been used. The positive role of land reform in all Baltic States is the restoration of land ownership, which has led to more targeted and intensive use of land in agriculture and other sectors. Land reform has created the preconditions for initiative and action of landowners in market economy. An additional effect is the development and implementation of state-of-the-art real estate registration systems in administration of each state. The article also analyses the shortcomings and problems encountered during the reform.

Authors: Diannissa Tiffianti , Qodir Abdul
Published: February 2021

This study aims to analyze the financial statements at IAIN Palangka Raya for three periods, namely the 2016-2018 period. This analysis was conducted to determine the financial performance of higher education when viewed from the ROA. It is fitting that the performance of IAIN Palangka Raya is carried out in accordance with Islamic law. In addition to providing information on financial conditions, the results of financial ratio analysis can also be used as a basis for decision making, especially to improve the financial condition of IAIN Palangka Raya in the future. The financial statements will be analyzed using financial ratio analysis, including: liquidity ratios, debt to equity ratios and debt to income ratios. Comparisons are also made using Sharia provisions. The results obtained from this study are that in the 2016-2018 period the value of the IAIN Palangka Raya financial ratio analysis is still very good. When viewed from the results of the t test, the liquidity ratio, debt to equity ratio and debt to income ratio have a partially positive and significant effect on financial performance. Meanwhile, if viewed from the results of the F test, the liquidity ratio, debt to equity ratio and debt to income ratio have a positive and significant effect simultaneously or together on financial performance in the IAIN Palangka Raya environment. So it can be said that IAIN Palangka Raya has performed well and is in accordance with sharia provisions.

Published: February 2021

The accurate comprehension of the risk drivers of different depository institutions is the key to their sustainable operation. In this paper, we analyze two stochastic approaches to model Non-Maturing Assets (NMAs) employing an Ornstein–Uhlenbeck process that can be used for the evaluation of the liquidity and interest risk of savings accounts in banks. We detail the models’ specifications, parameters, and simulation results. Furthermore, we examine the regular patterns, throughout the year, of the behavior of the volume of deposits into saving accounts in Colombia, in line with the results of other researchers in different countries. Finally, we found that a trend term should be incorporated into the model to capture the growth of the series.
Intramuscular myxoma of the left thigh: a rare tumor
Authors: Papageorgiou Michael S.
Published: February 2021

Background:

Intramuscular myxomas are rare tumors of mesenchymal origin and are usually presented in skeletal or cardiac muscles. They are of gelatinous texture and tend to reach large dimensions. They usually present as a painless mass which grows significantly with time, but rarely causing symptoms as pain or pressure to nearby structures. Intramuscular myxomas are usually diagnosed with ultrasound, computed tomography scan or magnetic resonance imaging scan, but the definite diagnosis is acquired by the histology report of the excised mass.

Case Presentation:

We report a rare case of a large (4 × 4 cm) symptomatic myxoma of the left thigh in a 49-year-old female.

Conclusion:

Intramuscular myxomas are rare tumors of mesenchymal origin, which can reach large dimensions. Excision is advised, even in smaller-sized masses, in order to have a definite diagnosis.
Design and Implementation of 6 DOF ROTARIC Robot Using Inverse Kinematics Method
Authors: Limanuel Fransisko , Susanto Calvin , Manalu Ferry Rippun Gideon
Published: February 2021

This paper will discuss the calculation of inverse kinematic which will be used to control the 6-DOF articulated robot. This robot consists of 6 Dynamixel MX-28 smart servo with OpenCM 9.04 microcontroller. The articulated robot has been simplified to 4-DOF because there are no obstacles in the work area and no special movements are required. The calculation method uses the intersection point equation between the ball and the line, so that it can make it easier to determine the point in calculating the kinematic inverse. The experiment is carried out using the desired position as input for the kinematic inverse to produce the angle of each joint. From the angle of each joint obtained, it will be entered into forward kinematic so that the end-effector position will be obtained. The desired position will be compared with the end-effector position, and then how much difference will be calculated. From the experimental results, it was found that the inverse kinematic method which has been inverted by the forward kinematic produces the same final position.

Keywords: 6-DOF manipulator, Articulated robot, inverse kinematics and forward kinematics, Dynamixel MX-28, OpenCM 9

Pengaruh Kombinasi Pemangkasan Ujung Magnet Permanen dan Axial Channel pada inti rotor terhadap Torka Cogging pada Generator Tipe Fractional Slot Number
Authors: Suherman Yudha , Nur Tajuddin
Published: February 2021

This paper is about to discuss the effect of combining a magnetic shaping technique with an axial channel in the rotor core to reduce the cogging torque of a permanent magnet synchronous generator. Computation process is performed by using the optimization response surface method. In this case, this research is done by employing two types of axial channel systems, namely circular and hexagonal. The axial channel area at the core of the engine rotor is 0.000279683 m2. Determination of magnetic shaping was carried out with an angle of 10 and a surface angle of 530. The effect of the combination of the cogging torque reduction technique with magnetic shaping and axal channel was analyzed by numerical method based on the finite element method (FEMM). Based on the analysis, it is found that the combination shows a decrease in cogging torque by 98% when compared with the cogging torque in the initial design (initial structure). Another advantage of the combination of the two cogging torque reduction techniques is that there is no significant increase in the magnetic flux density of the engine core. It can be said that the combination of the cogging torque reduction technique and the axial channel at the core of the engine rotor can significantly reduce the cogging torque.
Exploring Disruptive Thinking Possibilities in Construction and Engineering
Authors: Sittimont Kanjanabootra
Published: February 2021

Innovation adoption in construction and engineering projects is often claimed to be problematic and slow. Traditional analysis of innovation adoption is grounded in evidence- based practice and financial risk analysis. This has the effect of making innovation development in construction rarely able to disrupt industry. Innovation tends to occur in a drip feed like manner resulting in incremental and slower adoption. This is perceived as a problem for the construction industry. This paper uses the concept of Disruptive Thinking to examine a potential frame of reference for construction practitioners in their work and how they approach innovation adoption. The research uses interviews producing personal stories with professionals working on construction and engineering projects. The research shows that there is some evidence of use of disruptive mindsets by construction and engineering professionals, resulting in disruptive practice in certain sectors, not in the construction industry as a whole. The paper concludes that Disruptive Thinking is a starting point, and vehicle that can lead practitioners to more readily adopt innovation. Disruptive thinking can be a means to adoption when the mindset of evidence- based practice can be infiltrated.

Kuwait Oil Company (KOC) has a vast pool of heavy oil reservoirs. Cost-effective artificial lift technologies, are required to produce these reservoirs, optimally. With this strategic objective, pilot of newly developed ‘ES-HR-PCP’ (Electrical Submersible Hydraulically Regulated PCP) technology, is carried out in KOC. Scope of this technical paper is to highlight significance of this technology and to share results of our pilot studies, which are carried out to maximize cold heavy oil production.

With regard to our methodology, initially, techno-economic evaluation of ‘ES-HR-PCP’ system, is carried out. Selected well for the pilot, is having horizontal completion, with 3-1/2″ tubing and 7″ casing. Perforation is at 1900 feet MD (TVD at 686 feet). Oil API gravity is 17. Target liquid production rate is 200 b/d. After finalization of design, pilot of ‘ES-HR-PCP’ system is commissioned and pump performance is monitored for 6 months. Results are analyzed to determine success of the pilot. This study is based on actual field implementation and does not include lab studies.

Technology evaluation has shown that ‘ES-HR-PCP’ system has definite edge over conventional PCP system. Standard PCP can handle only 25% of free gas; while ‘ES-HR-PCP’ can handle 90% of free gas, due to its unique design concept. ‘ES-HR-PCP’ system uses electric cable (and not sucker rods) and down- hole permanent magnet motor (PMM), to transmit power. PMM system can deliver more production, at higher speed; while expending less power. All these factors enable ‘ES-HR-PCP’, to be installed, near to the perforation zone, especially, in horizontal wells, thereby, allowing to attain lowest possible pump intake pressure and maximize production.

During the pilot, peak liquid rate of 270 b/d (at 220 rpm), is achieved with installed ‘ES-HR-PCP’ system. Simulation studies also indicated that this technology could handle more than 40% of free gas, for given operating conditions. It is relevant to note that peak liquid rate of 223 b/d (at 375 rpm), is achieved, when this particular well, was installed with standard PCP, earlier. Substantial savings in power consumption is also witnessed by using ‘ES-HR-PCP’ system. Overall, performance of ‘ES-HR-PCP’ system, is observed highly encouraging during the pilot period.

It is inferred from our studies that ‘ES-HR-PCP’ technology can offer distinct advantages over standard PCP, to accomplish, enhanced oil gain, operational flexibility and savings in operating expenses. Findings of this study can serve, as a valuable reference, for effective exploitation of heavy oil reservoirs of similar nature.

Spatial search using flip-flop quantum walk
Authors: J. Abhijith , Patel Apoorva
Published: February 2021

We analyse the eigenvalue and eigenvector structure of the flip-flop quantum walk on regular graphs, explicitly demonstrating how it is quadratically faster than the classical random walk. Then we use it in a controlled spatial search algorithm with multiple target states, and determine the oracle complexity as a function of the spectral gap and the number of target states. The oracle complexity is optimal as a function of the graph size and the number of target states, when the spectral gap of the adjacency matrix is $\Theta(1)$. It is also optimal for spatial search on D>4 dimensional hypercubic lattices. Otherwise it matches the best result available in the literature, with a much simpler algorithm. Our results also yield bounds on the classical hitting time of random walks on regular graphs, which may be of independent interest.
Perfect sampling for quantum Gibbs states
Authors: Franca Daniel S.
Published: February 2021

We show how to obtain perfect samples from a quantum Gibbs state on a quantum computer. To do so, we adapt one of the ``Coupling from the Past''-algorithms proposed by Propp and Wilson. The algorithm has a probabilistic run-time and produces perfect samples without any previous knowledge of the mixing time of a quantum Markov chain. To implement it, we assume we are able to perform the phase estimation algorithm for the underlying Hamiltonian and implement a quantum Markov chain such that the transition probabilities between eigenstates only depend on their energy. We provide some examples of quantum Markov chains that satisfy these conditions and analyze the expected run-time of the algorithm, which depends strongly on the degeneracy of the underlying Hamiltonian. For Hamiltonians with highly degenerate spectrum, it is efficient, as it is polylogarithmic in the dimension and linear in the mixing time. For non-degenerate spectra, its runtime is essentially the same as its classical counterpart, which is linear in the mixing time and quadratic in the dimension, up to a logarithmic factor in the dimension. We analyze the circuit depth necessary to implement it, which is proportional to the sum of the depth necessary to implement one step of the quantum Markov chain and one phase estimation. This algorithm is stable under noise in the implementation of different steps. We also briefly discuss how to adapt different ``Coupling from the Past''-algorithms to the quantum setting.
Stabiliser states are efficiently PAC-learnable
Authors: Rocchetto Andrea
Published: February 2021

The exponential scaling of the wave function is a fundamental property of quantum systems with far reaching implications in our ability to process quantum information. A problem where these are particularly relevant is quantum state tomography. State tomography, whose objective is to obtain an approximate description of a quantum system, can be analysed in the framework of computational learning theory. In this model, Aaronson (2007) showed that quantum states are Probably Approximately Correct (PAC)-learnable with sample complexity linear in the number of qubits. However, it is conjectured that in general quantum states require an exponential amount of computation to be learned. Here, using results from the literature on the efficient classical simulation of quantum systems, we show that stabiliser states are efficiently PAC-learnable. Our results solve an open problem formulated by Aaronson (2007) and establish a connection between classical simulation of quantum systems and efficient learnability.

The increasingly high quality curriculum that will be implemented certainly has to be accompanied by needs with good quality standards as well. It is often difficult for the education provider to provide the need for tools to support practice, with high prices and modules that are not always available making it difficult for students to study independently in these circumstances. Game is one of the media to be able to do things in the real world without the need to have real equipment, such as education games with the genre of serious games that have been developed as alternative media of modern education, accompanied by Augmented Reality (AR) technology, This simulation can be achieved by pretty good. So, the purpose of this research is to design an educational game with a simulation game genre that can represent basic electronic practice by Vocational High School students so that students can learn independently more easily and lower costs and reduce the risk of errors when do practical work directly. The game is designed with the Design Thinking approach with Mobile Augmented Reality (MAR) to simulate virtual objects. Based on the results of the game test evaluation through a questionnaire on vocational students majoring in Communication Electronics as many as 30 students, where aspects were tested terari from the respondent's background, interaction with the User Interface, and User Experience obtained by respondents from game simulations showed that the average respondent was interested in doing basic electronics assembly through simulation games with a score of 83.10% and can receive a pretty good education through the game with 79.16% test results.

Authors: ÖZ Özge , IŞIKSAL Mine
Published: February 2021

Amaç: Bu çalışmanın amacı ortaokul yedinci sınıf öğrencilerinin istatistiksel araştırma sürecini anlamlandırmalarını incelemektir. Bu bağlamda, yedinci sınıf öğrencilerine gerçek veri kümeleri verilerek istatistiksel araştırma sürecini oluşturan problemi belirleme, veri toplama, veriyi analiz etme ve sonuçları yorumlama aşamalarının her birindeki seviyeleri belirlenmiştir.

Yöntem: Bu çalışmada, kesitsel tarama deseni kullanılmıştır. Öğrencilerin istatiksel araştırma sürecini anlamlandırmalarının belirlenmesi için öğrencilerin hazırlanan teste verdikleri cevaplar derinlemesine incelenmiştir. Çalışmanın örneklemini, 2017-2018 eğitim öğretim yılında İstanbul’un Pendik ilçesinde öğrenim gören 121 yedinci sınıf öğrencisi oluşturmaktadır.

Bulgular: Çalışmanın sonuçları, öğrencilerin istatistiksel araştırma sorusu oluşturma seviyelerinin genel olarak orta ve yüksek seviyede olduğunu göstermiştir. Öte yandan, öğrencilerin araştırma sürecinde en yabancı oldukları kısmın, veri toplama yöntemine karar vermek olduğu görülmüştür. Öyle ki, birçok öğrencinin, ‘aritmetik ortalama, medyan ve mod’ gibi merkezi eğilim ölçülerini veri toplama yöntemi olarak belirttikleri görülmüştür. Ayrıca, öğrencilerin verileri analiz etmede orta seviyede oldukları görülmüştür. Diğer bir deyişle, öğrencilerin hem veri türüne hem de karşılaştırma yapmak gibi verilen durumların amacına uygun grafik türünü seçmekte zorlandıkları gözlemlenmiştir. Son olarak, öğrencilerin sonuçları yorumlama seviyelerinin genel olarak orta veya ileri düzey olduğu belirlenmiştir. Diğer bir deyişle, öğrencilerin büyük çoğunluğunun, grafik üzerinde verilen bir sıklığı ifade etmek yerine grafikte verilen bilgileri bütün olarak ele alan, karşılaştıran ya da grafikte açıkça verilmeyen ilişkilere değinen yorumlar yaptıkları gözlemlenmiştir.

Sonuçlar ve Öneriler: Bu çalışmanın bulgularının diğer yedinci sınıflara genellenebilmesi için seçkisiz örnekleme yöntemi kullanılarak tekrarlanabilir. Ayrıca, öğrencilerin istatiksel süreçteki hatalarının ve zorluklarının sebepleri incelenebilir.
