Abstract
Wind power, as a new energy generation technology, has been applying widely and growing rapidly, which make it become the main force of renewable energy. However, wind speed sequence has its own character of the intermittent and uncertainty, which brings a great challenge to the safety and stability of the power grid, one of the valid ways solving the problem is improving the wind speed predicting accuracy. Therefore, given atmospheric disturbances, we firstly used empirical mode decomposition (EMD) to deal with the non-linear wind speed sequence, and combined with strong adaptive and self-learning ability of BP neural network, then, a wind speed prediction model, EMD-BP neural network based on Lorenz disturbance, was proposed. Finally, it was to made use of actual wind speed data to take a simulation experiment and explored the improvement effect of the preliminary forecasting sequence of wind speed influenced by Lorenz equation in the transient chaos and chaos. The results show that, the improved model weakened the random fluctuation of wind speed sequence, effectively corrected the wind speed sequences initial prediction values, and made a great improvement for the short-term wind speed prediction precision. This research work will help the power system dispatching department adjust the dispatching plan in time, formulate the wind farm control strategy reasonably, reduce the impact brought by wind power grid connection, increase the wind power penetration rate, and then promote the global energy power market innovation.
Performance optimization of permanent magnet synchronous motor by cogging torque reduction
Authors: Sarac Vasilija 
Published: July 2019

Abstract
The development of the robotics and the automation and the need for the motors that can work in the applications that require high speed, precision and increased efficiency have led to the increased use of permanent magnet synchronous motors and their continuous development in terms of improving their performance. Cogging torque is one of the features of these types of the motors that deteriorate motor performance especially at low speeds. Therefore, in this paper the method of genetic algorithms (GA) is applied as an optimization tool, for minimizing the cogging torque without changing the other important operating parameters like output power, torque or current. Even more, the optimized motor model has improved efficiency compared to the starting model and has the decreased weight of the permanent magnets. The optimization is done by changing the rotor design in terms of the magnet thickness, pole span and shape of the magnets. Finite elements (FE) models of the optimized and the basic motor were derived and from them the flux density distribution in the motor cross section and in the air gap was calculated. In addition, the improvement of the motor operation is observed from the torque characteristics calculated by the FE models.

Authors: Twumasi Baidenger Agyekum , Li Jia-Lin 
Published: July 2019

Abstract
Bowtie antenna-based time reversal mirror (TRM), incorporating with randomly distributed and arbitrarily shaped wire metamaterials medium, is proposed to realize super-resolution target detection. The achieved performance for standard and scatterer bowtie antenna TRM is compared and discussed. The dual-band bowtie antennas resonate at 2.45 GHz and 5.2 GHz and a super-resolution of 0.0817 of the free-space wavelength at 2.45 GHz has been achieved. For the first time, studies show that the TRM with microstructure perturbations (namely scatterers) can enhance the resolution in some cases. Proposing a method of super-resolving transmission of electromagnetic waves is very important to realize multi-independent channels in a compact space for the related applications.
On interactions of static magnetic fields
Authors: Zor Ömer 
Published: July 2019

Abstract
We investigated the interaction energy of a Gilbertian magnetic charge with each of the “point” magnetic field sources. Finally we extrapolated a Dirac string can only be defined if there is at most one Dirac monopole in the medium. If there is only one Dirac monopole/string in the universe, the probability of detecting it is essential zero, such that Dirac’s monopole would remain just a “theorist’s particle”.

Published: July 2019

Abstract
Congenital malalignment of the toenail is characterized by the lateral (rarely medial) deviation of nail plates that affects mostly the great toes from one foot or both, but has also been described on other toes, even on the hands. This nail disease is still considered a rare entity, although it is not a rare clinical observation in daily practice. We present a few cases in children and adults, highlighting the diagnosis made by clinical observation, regardless of the different grades of severity of the nail disease. Conclusion: It is of great importance to clinically recognize this entity in young children and to make the correct recommendations.

Published: July 2019

Abstract

Background: Daclizumab is a humanized monoclonal antibody against the D-subunit (CD25) of the high-affinity interleukin (IL)–2 receptor, used for the treatment of relapsing-remitting multiple sclerosis with a large spectrum of cutaneous adverse reactions. Case presentation: We present the case of a middle-aged man treated with daclizumab for multiple sclerosis, who developed skin reactions difficult to evaluate. A 4 mm punch-biopsy was taken from the plantar area. Histological examination of the biopsy revealed hyperkeratosis and acanthosis but no parakeratosis, while a discrete inflammatory infiltrate was noticed around vessels in the dermis. Treatment with fluconazole 50 mg/day for 10 days, moisturizers, and grade I topical steroids was followed by slight improvement of the clinical picture. Treatment with daclizumab was not discontinued. Conclusion: The clinical efficacy and side effects of daclizumab have to be reported and confirmed in clinical practice in the following years. Any clinical report can contribute to validate the efficacy and risk of the drug’s administration. Any type of adverse skin reaction must be reported for clarifying the diagnosis.
Uncommon Differential Diagnosis of Acute Right-sided Abdominal Pain – Case Report
Authors: Kwizera Cédric , Wagner Benedikt , Wagner Johannes B. , Molnar Călin 
Published: July 2019

Abstract
The appendix is a worm-like, blind-ending tube, with its base on the caecum and its tip in multiple locations. Against all odds, it plays a key role in the digestive immune system and appendectomy should therefore be cautiously considered and indicated. We report the case of a 45-year-old male with a known history of Fragile-X syndrome who presented to the emergency department with intense abdominal pain and was suspected of acute appendicitis, after a positive Dieulafoy’s triad was confirmed. The laparoscopic exploration showed no signs of inflammation of the appendix; nonetheless, its removal was carried out. Rising inflammatory laboratory parameters led to a focused identification of a pleural empyema due to a tooth inlay aspiration. Our objective is to emphasize the importance of a thorough anamnesis, even in cases of mentally impaired patients, as well as to highlight a rare differential diagnosis for appendicitis. Acute appendicitis is an emergency condition that requires a thorough assessment and appropriate therapy. Clinical examinations are important, but in this particular case, imaging methods had a much more important role in establishing the right treatment approach. Furthermore, the signs of acute appendicitis are mimicked by several medical conditions including respiratory tract infections.

Illegal Access to a Computer System from the Standpoint of the Current Criminal Code
Authors: Drăgan Alin Teodorus 
Published: July 2019

Abstract
One of the forms that cybercrime can take at present is illegal access to a computer system. From the very beginning, the world of computers and of the Internet was based on imperfections, defects, and sometimes on poorly understood processes. We might even call this fact “the original sin” of the Internet. In the end, it is not only computer scientists who have come to exploit such defects, but also criminals. In the real world, there are people who break into homes and take away everything they find valuable. In the virtual world, there are individuals who penetrate into computer systems and steal all valuable data.
Decision-Making in the International Monetary Fund: Implications for Sovereign Equality of States
Authors: Ansong Alex 
Published: July 2019

Abstract
The International Monetary Fund (IMF) is one of the post-Second World War international organizations set up to promote good international economic cooperation among states. Unlike international organizations like the United Nations (UN) and the World Trade Organization (which succeeded the General Agreement on Tariff and Trade 1947), decision-making in the IMF is quite peculiar in that it is based on the joint stock company model where the value of shares determine the value of a member’s vote. Thus the principle of sovereign equality of states that underpins the one-member-one-vote system in the UN and WTO is absent in the IMF. This paper discusses the various decisionmaking organs in the IMF and concludes with a discussion on the sovereignty implications of the use of IMF conditionalities in the giving of loans, especially to developing countries.
The Defence of Necessity in International Law and Investor Versus State Dispute Settlement
Authors: AlModarra Bader Bakhit M 
Published: July 2019

Abstract
The ability of foreign investors to sue host states without reliance on diplomatic protection is one of the most important developments in international investment law in the post-World War II era. The rise of investor-state dispute settlement under international regimes like the Convention Establishing the International Centre for the Settlement of Investment Disputes (ICSID Convention) raises some concerns from states regarding loss of sovereignty. However, there are defences available to states when they intervene in their economies for purposes like public utility or the need to safeguard an essential interest. Thus in spite of treaty commitments that bind states to protect the investments of foreign investors within their domains, there are available defences for their intervention in their economies even if such interventions become inimical to the interests of foreign investors and could, prima facie, raise the possibility of infringements of the rights of foreign investors. One of such defences available to states is the principle of necessity. This article explores the principle of necessity in international law and how it operates as a defence for states in investor-state dispute settlement. It also conducts analysis of the Annulment Decision in the CMS v Argentina case to shed light on the principle of necessity.

SummaryBackgroundThe purpose of the present study was to assess saliva reliability in diagnosis and monitoring type 2 diabetes instead of blood.MethodsBlood and unstimulated whole saliva were collected from 300 type 2 diabetic subjects and 300 healthy controls in fasting. Then, the salivary flow rate was calculated. All parameters including glucose, urea, amylase, total protein, albumin, C-reactive protein (CRP), immunoglobulin A (IgA), potassium, calcium and chloride were assessed in the supernatant, using an autoanalyzer. Oral exam was conducted by a single examiner on full mouth excluding third molars. Statistical analysis was performed by the SPSS 20.0 version.ResultsSaliva screening showed that glucose, urea, amylase, total protein, potassium, calcium and chloride were significantly higher in patients compared to controls (p < 0.05). Whereas, the IgA level and salivary flow rate were significantly reduced in patients (p < 0.05). No significant difference was found in albumin and CRP levels (p = 0.05). There was a significant positive correlation between salivary and plasma glucose levels (r = 0.887, and r = 0.900, p < 0.001), as well as, salivary and blood urea (r = 0.586, and r = 0.688, p < 0.001) in patients and controls, respectively.ConclusionsFrom this study, saliva could be suggested as a useful diagnostic tool for type 2 diabetes.

Published: July 2019

Summary

Background
Our aim was to study changes in the serum proteomic profile in coronary atherosclerosis.

Methods
The study involved two groups of patients: 1) men with coronary heart disease and coronary atherosclerosis (n = 15); 2) control (n = 15): men without coronary heart disease. The object of this study was blood serum. Separation of proteins for the investigation of differences in serum protein components was performed by two-dimensional electrophoresis. Identification of protein fractions was carried out using peptide mass maps by the matrix-assisted laser desorption ionization method.

Results
In blood serum samples from patients with coronary atherosclerosis, protein separation in two-dimensional gels with mass-spectrometric identification revealed an increase of some proteins: hemopexin, transthyretin (monomeric form), retinol-binding protein 4, and components of the complement system: C3 (chain B) and C9. There was a decrease of some proteins: kininogen, zinc finger protein 133, and B-cell CLL/lymphoma 6 member B protein. Comparisons between the experimental and control group were carried out in protein fractions where the protein amount differed more than 1.5-fold (p < 0.05).

Conclusions
Proteome profiling of serum revealed a change in the content of kininogen, hemopexin, transthyretin, retinol-binding protein, and proteins of the complement system (C9, and C3) in coronary atherosclerosis. The contribution to the differential expression of a protein was often made by isoforms of the protein, particularly transthyretin. The change in the concentrations of functionally interacting proteins, such as transthyretin and retinol-binding protein, were noted.
Rs1799817 in INSR associates with susceptibility to polycystic ovary syndrome
Authors: Daghestani Maha H. 
Published: July 2019

Summary

Background
Insulin and its receptor (INSR) have been implicated in the etiology of the polycystic ovarian syndrome (PCOS). Here, we investigate the association between INSR rs1799817 polymorphism and PCOS in Saudi Arabian women.

Methods
study group included 126 PCOS women and 118 normo-ovulatory matched controls. The demographic data was recorded, and the plasma levels of glucose, lipids, leptin, E2, LH, FSH, T, SHBG, and insulin were determined. The genotypic and allele frequencies of rs1799817 were evaluated in both PCOS and control group. Polymerase chain reaction (PCR) was used to amplify Exon 17 of the INSR gene, and the amplified products were analyzed by direct sequencing. A single-nucleotide polymorphism (C to T) was found at locus 10923 (His1058) of rs1799817.

Results
In the PCOS group, the mutant allele T occurs at a significantly higher frequency (0.306) compared to the control group (0.174) (p<0.001). It shows a dominant effect and elevates the relative risk of PCOS even in the heterozygotes (RR=2.82). After stratification of the participants by body mass index, the frequency of T allele was significantly higher in the lean patients with PCOS compared to the lean control. The obese PCOS also had a higher frequency than the obese control, but the difference was not statistically significant. Several parameter values were affected by the INSR genotype, particularly W/H ratio, lipid, insulin and glucose levels and insulin resistance in PCOS patients.

Conclusion
The INSR gene polymorphism rs1799817 is a susceptibility locus associated with PCOS in Saudis and associated metabolic and hormonal changes, particularly, in the lean PCOS females.

Published: July 2019

SummaryBackgroundEarly diagnosis of acute kidney injury (AKI) after cardiac surgery is based on serum creatinine which is neither a specific nor a sensitive biomarker. In our study, we investigated the role of serum Klotho in early prediction of AKI after cardiac surgery using cardiopulmonary bypass (CPB).MethodsThe included patients were classified into three groups according to AKI stages using KDIGO criteria. The measurements of creatinine and Klotho levels in serum were performed before surgery, at the end of CPB, 2 hours after the end of CPB, 24 hours and 48 hours postoperatively.ResultsSeventy-eight patients were included in the study. A significant increase of creatinine levels (p<0.001) was measured on the first day after the surgery in both AKI groups compared to the non-AKI group. However, a significant difference between AKI-2 and AKI-1 groups (p=0.006) was not measured until the second day after the operation. Using decision trees for classification of patients with a higher or lower risk of AKI we found out that Klotho discriminated between the patients at low risk of developing more severe kidney injury in the first hours after surgery and the patients at high risk better than creatinine. Adding also the early measurements of creatinine in the decision tree model further improved the prediction of AKI.ConclusionSerum Klotho may be useful to discriminate between the patients at lower and the patients at higher risk of developing severe kidney injury after cardiac surgery using CPB already in the first hours after surgery.

SummaryBackgroundRecurrent pregnancy loss (RPL) is a heterogeneous condition affecting up to 5% of women of reproductive age. Inherited thrombophilia have been postulated as one of the causes of RPL. Here we examined the prevalence of nine thrombophilic gene polymorphisms among women with history of recurrent miscarriages and fertile controls.MethodsThe study included 70 women with history of at least three early pregnancy losses and 31 fertile controls with no miscarriages. We investigated mutations in genes responsible for clotting and fibrinolysis, including factor V (FV) Leiden, FV H1299R, factor II (FII) G20210A, methylene tetrahydrofolate reductase (MTHFR) C677T and A1298C, factor XIII (FXIII) V34L, plasminogen activator inhibitor-1 (PAI-1) 4G/5G and endothelial protein C receptor (EPCR) H1 and H3 haplotypes using reverse polymerase chain reaction ViennaLab cardiovascular disease StrippAssays.ResultsOur results showed no significant increase in prevalence of tested polymorphisms in women with RPL. However, relative risk for PRL among women heterozygous for FXIII V34L was 2.81 times increased (OR 2.81, 95% CI 1.15–6.87, P=0.023). Haplotype analysis showed that combined presence of high-risk genotypes for FXIII and PAI-1 significantly increases risk for RPL (OR 13.98, CI 95% 1.11–17.46, P=0.044).ConclusionsThis is the first study in Serbian population that investigated prevalence of FVR2, A1298C, FXIII V34L and EPCR gene variants. Compound heterozygosity for FXIII V34L and PAI-1 4G is significant risk factor for recurrent miscarriage. Our results should be viewed in context of small case-control study, so further large prospective studies are need for confirmation of our findings.
