Authors: Pongsakornsathien Nichakorn , Gardi Alessandro , Lim Yixiang , Sabatini Roberto , Kistan Trevor
Published: June 2022

Emerging Air Traffic Management (ATM) and avionics human–machine system concepts require the real-time monitoring of the human operator to support novel task assessment and system adaptation features. To realise these advanced concepts, it is essential to resort to a suite of sensors recording neurophysiological data reliably and accurately. This article presents the experimental verification and performance characterisation of a cardiorespiratory sensor for ATM and avionics applications. In particular, the processed physiological measurements from the designated commercial device are verified against clinical-grade equipment. Compared to other studies which only addressed physical workload, this characterisation was performed also looking at cognitive workload, which poses certain additional challenges to cardiorespiratory monitors. The article also addresses the quantification of uncertainty in the cognitive state estimation process as a function of the uncertainty in the input cardiorespiratory measurements. The results of the sensor verification and of the uncertainty propagation corroborate the basic suitability of the commercial cardiorespiratory sensor for the intended aerospace application but highlight the relatively poor performance in respiratory measurements during a purely mental activity.

Atopic dermatitis (AD) is a common chronic inflammatory skin dermatosis condition due to skin barrier dysfunction that causes itchy, red, swollen, and cracked skin. Currently, AD severity clinical scores are subjected to intra- and inter-observer differences. There is a need for an objective scoring method that is sensitive to skin barrier differences. The aim of this study was to evaluate the relevant skin chemical biomarkers in AD patients. We used confocal Raman micro-spectroscopy and advanced machine learning methods as means to classify eczema patients and healthy controls with sufficient sensitivity and specificity. Raman spectra at different skin depths were acquired from subjects’ lower volar forearm location using an in-house developed handheld confocal Raman micro-spectroscopy system. The Raman spectra corresponding to the skin surface from all the subjects were further analyzed through partial least squares discriminant analysis, a binary classification model allowing the classification between eczema and healthy subjects with a sensitivity and specificity of 0.94 and 0.85, respectively, using stratified K-fold (K = 10) cross-validation. The variable importance in the projection score from the partial least squares discriminant analysis classification model further elucidated the role of important stratum corneum proteins and lipids in distinguishing two subject groups.

The aim of this study is to evaluate the performance of the Radialis organ-targeted positron emission tomography (PET) Camera with standardized tests and through assessment of clinical-imaging results. Sensitivity, count-rate performance, and spatial resolution were evaluated according to the National Electrical Manufacturers Association (NEMA) NU-4 standards, with necessary modifications to accommodate the planar detector design. The detectability of small objects was shown with micro hotspot phantom images. The clinical performance of the camera was also demonstrated through breast cancer images acquired with varying injected doses of 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (18F-FDG) and qualitatively compared with sample digital full-field mammography, magnetic resonance imaging (MRI), and whole-body (WB) PET images. Micro hotspot phantom sources were visualized down to 1.35 mm-diameter rods. Spatial resolution was calculated to be 2.3 ± 0.1 mm for the in-plane resolution and 6.8 ± 0.1 mm for the cross-plane resolution using maximum likelihood expectation maximization (MLEM) reconstruction. The system peak noise equivalent count rate was 17.8 kcps at a 18F-FDG concentration of 10.5 kBq/mL. System scatter fraction was 24%. The overall efficiency at the peak noise equivalent count rate was 5400 cps/MBq. The maximum axial sensitivity achieved was 3.5%, with an average system sensitivity of 2.4%. Selected results from clinical trials demonstrate capability of imaging lesions at the chest wall and identifying false-negative X-ray findings and false-positive MRI findings, even at up to a 10-fold dose reduction in comparison with standard 18F-FDG doses (i.e., at 37 MBq or 1 mCi). The evaluation of the organ-targeted Radialis PET Camera indicates that it is a promising technology for high-image-quality, low-dose PET imaging. High-efficiency radiotracer detection also opens an opportunity to reduce administered doses of radiopharmaceuticals and, therefore, patient exposure to radiation.
Defects Recognition Algorithm Development from Visual UAV Inspections

Published: June 2022

Aircraft maintenance plays a key role in the safety of air transport. One of its most significant procedures is the visual inspection of the aircraft skin for defects. This is mainly carried out manually and involves a high skilled human walking around the aircraft. It is very time consuming, costly, stressful and the outcome heavily depends on the skills of the inspector. In this paper, we propose a two-step process for automating the defect recognition and classification from visual images. The visual inspection can be carried out with the use of an unmanned aerial vehicle (UAV) carrying an image sensor to fully automate the procedure and eliminate any human error. With our proposed method in the first step, we perform the crucial part of recognizing the defect. If a defect is found, the image is fed to an ensemble of classifiers for identifying the type. The classifiers are a combination of different pretrained convolution neural network (CNN) models, which we retrained to fit our problem. For achieving our goal, we created our own dataset with defect images captured from aircrafts during inspection in TUI’s maintenance hangar. The images were preprocessed and used to train different pretrained CNNs with the use of transfer learning. We performed an initial training of 40 different CNN architectures to choose the ones that best fitted our dataset. Then, we chose the best four for fine tuning and further testing. For the first step of defect recognition, the DenseNet201 CNN architecture performed better, with an overall accuracy of 81.82%. For the second step for the defect classification, an ensemble of different CNN models was used. The results show that even with a very small dataset, we can reach an accuracy of around 82% in the defect recognition and even 100% for the classification of the categories of missing or damaged exterior paint and primer and dents.
Design Optimization of PCB-Based Rotary-Inductive Position Sensors
Authors: Hoxha Aldi , Passarotto Mauro , Qama Gentjan , Specogna Ruben
Published: June 2022

This paper introduces a novel methodology to optimize the design of a ratiometric rotary inductive position sensor (IPS) fabricated in printed circuit board (PCB) technology. The optimization aims at reducing the linearity error of the sensor and amplitude mismatch between the voltages on the two receiving (RX) coils. Distinct from other optimization techniques proposed in the literature, the sensor footprint and the target geometry are considered as a non-modifiable input. This is motivated by the fact that, for sensor replacement purposes, the target has to fit a predefined space. For this reason, the original optimization technique proposed in this paper modifies the shape of the RX coils to reproduce theoretical coil voltages as much as possible. The optimized RX shape was obtained by means of a non-linear least-square solver, whereas the electromagnetic simulation of the sensor is performed with an original surface integral method, which are orders of magnitude faster than commercial software based on finite elements. Comparisons between simulations and measurements performed on different prototypes of an absolute rotary sensor show the effectiveness of the optimization tool. The optimized sensors exhibit a linearity error below 0.1% of the full scale (FS) without any signal calibration or post-processing manipulation.

Published: June 2022

This article discusses the use of a handheld electronic nose to obtain information on the presence of some aromatic defects in natural cork stoppers, such as haloanisoles, alkylmethoxypyrazines, and ketones. Typical concentrations of these compounds (from 5 to 120 ng in the cork samples) have been measured. Two electronic nose prototypes have been developed as an instrumentation system comprise of eight commercial gas sensors to perform two sets of experiments. In the first experiment, a quantitative approach was used whist in the second experiment a qualitative one was used. Machine learning algorithms such as k-nearest neighbors and artificial neural networks have been used in order to test the performance of the system to detect cork defects. The use of this system tries to improve the current aromatic defect detection process in the cork stopper industry, which is done by gas chromatography or human test panels. We found this electronic nose to have near 100 % accuracy in the detection of these defects.
Simultaneous Determination of Caffeic Acid and Ferulic Acid Using a Carbon Nanofiber-Based Screen-Printed Sensor
Authors: Bounegru Alexandra Virginia , Apetrei Constantin
Published: June 2022

This work aims to achieve the simultaneous qualitative and quantitative determination of two hydroxycinnamic acids (ferulic acid and caffeic acid) from standard solutions and from a phyto-homeopathic product using a carbon nanofiber-based screen-printed sensor (CNF/SPE). The two compounds are mentioned in the manufacturer’s specifications but without indicating their concentrations. The stability and reproducibility of the CNF/SPE were found to be effective and the sensitivity was high for both caffeic acid—CA (limit of detection 2.39 × 10−7 M) and ferrulic acid—FA (limit of detection 2.33 × 10−7 M). The antioxidant capacity of the compounds in the analyzed product was also determined by the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The electrochemical method was efficient and less expensive than other analytical methods; therefore, its use can be extended for the detection of these phenolic compounds in various dietary supplements or pharmaceutical products.

Published: June 2022

The study aims to treat artificial wastewater contaminated with copper (II) ions by reverse osmosis using (SEPA CF042 Membrane Test Skid-TFC BW30XFR). Several concentrations of feedstock were prepared. Different operating pressure, temperature, and flow rate were applied. The effect of these operating conditions on both the amount of Cu (II) removal and the permeate flux was monitored. The results of the study revealed that both the permeate flux and Cu (II) removal amount were directly proportional to the operating pressure and feed temperature but inversely proportional to the feed concentration. In contrast, the feed flow rate showed a negligible effect on the permeate flux and Cu (II) removal amount. The temperature correction factor (TCF) of the membrane was calculated and was found to be directly proportional to the feed temperature but inversely proportional to the applied pressure. It was seen that the concentration and flow rate of that feed did not affect the temperature correction factor. Mathematical models have been developed based on these experimental data for both permeate flux and the Cu (II) removal. It was noted that the permeate flux model matched the experimental data, while the Cu (II) removal model did not show a perfect match. In addition to the above, the research highlights for subsequent studies the possibility of a deep link between experimental work and mathematical models.

Some Aspects of Economic Diplomacy of Latin American countries in the XIX century
Authors: Lezginсev Y. M.
Published: June 2022

This brief survey of 19th century Latin America countries economy offered for reader’s attention represents the second article within a series of papers thought by the author in order to follow historical genesis of economical complex of regional states. The indicated period is to be of special interest due to the fact that within it happened development of its specialization accompanied by fundamental processes in commodity production based on destructing of communal Indian land ownership, abolition of slavery and stimulating of European immigration. The experience obtained during application of liberal conceptions in Latin America’s states at the beginning of capitalist economy clearly showed senselessness to borrow alien ideology without taking into consideration local specifics, because this fact frequently contradicted the needs of authentic development in the receiving countries. As a rule these conceptions represented requirements of foreign agents as well as interests of small part of local society aimed at intensification in exploitation of labour and natural resources. Moreover, its implementation led to strengthening of financial and political dependence, imposing rapid economic transformation and converting young creole republics into pseudo-state political formations («banana republics» in Central America, Puerto Rico, Cuba). Submitting more advanced South American areas (La Plata, Brazil, Peru) neocolonial methods have been tested: ruinous foreign loans, direct and indirect control of local industries and change of its structure in the interests of overseas investors. Here could be mentioned artificial boom of raw material export, control and destruction of local processing works. The said economic paradigm conditioned convulsive forms of social life: appearance of caudillos, dictatorships and authoritarian regimes as well as interregional conflicts (Pacific «Salitre» War between Chile, Peru and Bolivia, intervention of Triple Alliance in Paraguay, separation of Panama for constructing of interocean channel etc.). In particular, dynamics and correlation of these events in context of struggle for real national emancipation laid foundations for contemporary state of economic situation in each country including its alliances and determined its peripheral position in international division of labour. This phenomenon should be considered for building effective cooperation with the most of regional partners.

Russia and Latin American states are united by a long history of mutually beneficial and multi-format cooperation. The Parties fairly share common values and the vector of fundamental principles in international politics. The inadmissibility of a unipolar world is also mutually recognized and any segregation in the world community is denied. The Latin Americas states remain reliable partners of Russia in the face of escalating Russophobia and global disinformation. Despite unilateral Western sanctions and harsh pressure from the United States, the LAC states express support and solidarity with Russia, maintaining trade and diplomatic contacts at the same level. The countries of the Latin American region are interested in increasing bilateral trade and, together with Russian partners, are looking for new ways to develop trade cooperation. Two-way dialogue channels are still permanently used for the direct transmission of information. Russian diplomatic missions are actively working to maintain a positive image of Russia in the region and are deepening all-round ties with the countries of Latin America and the Caribbean. In addition, Russian diplomatic missions efficiently cope with delivering objective and truthful information to the public in the Latin America and develop innovative response approaches in the context of information warfare. The active work of Russian diplomatic missions in social networks and messengers attracts the attention of foreigners and compatriots, creating a solid foundation for opposing discrediting in the media and the Internet space. No hostile action will outweigh the importance of the strategic relationship between Russia and the states of Latin America. Historically, the parties have opposed the sanctions strategy of putting pressure on sovereign states and hard influence on the state will.

Responses to external repeated perturbations vary with time intervals
Authors: Kim Dongwon , Hwang Jong-Moon
Published: June 2022

While perturbation training is known to be effective in reducing fall risk, it is unclear whether the interval of perturbations affects motor response. We investigate postural responses that could vary with the interval of perturbations, probably leading to different contributions of relevant learning substrates. A total of 12 male volunteers with no neurological deficits (age: 33.33±3.12 S.D.) experienced two sequences of perturbations. Two sequences of perturbations were designed and administered in turn: the first sequence consisted of 24-time repeated perturbations with an interval of 5 seconds, while the second sequence consisted of ones with an interval of 2.5 seconds. A perturbation of a smaller magnitude was inserted into each sequence as a catch trial. Perturbations were given by a force plate moving in the anterior-posterior direction. The magnitude of the excursions of the center of pressure (COP) and ankle angle in response to perturbations with a longer interval is greater in comparison to that with a shorter interval (P < 0.05). A difference in responses to the perturbation following the catch trial appears in COP (P < 0.05), not in ankle angle (P > 0.05). These results suggest that while contraction of agonist muscles and co-contraction of antagonistic muscle pairs across the ankle joint for stability operate independently of each other, the refinement of the neuromotor system for a newly trained response can be modulated with stimulus intervals. The dependency of postural responses on the interval could imply that the strength of the learning effect varies with stimulus intervals.

The purpose of this study was to determine the influence of infrastructure development policies on provision of quality teaching and learning of early childhood education in Mbita Sub-County Homabay County, Kenya. The study adopted organizational learning theory. Descriptive survey research design was employed. The sample size for this study was 27 head teachers, 54 ECD teachers, 6 Zone ECD Supervisors. The study used simple random sampling and purposive sampling technique. The tools used in this study were questionnaires and interview schedules. Quantitative data was analyzed using descriptive statistics while qualitative data was analyzed according to emerging themes. The analyzed data was presented using tables. The study findings showed that 79.49% (mean=3.97 and Std Dev=1.093) of the respondents accepted that the county has policies guiding classroom structuring which has enhanced teaching and learning. In conclusion, school infrastructures like toilets, play grounds, classrooms, and libraries are constructed according to the ministry of education standards. Toilets, pit latrines are located far from the classrooms to avoid air pollution and provide good learning environment. The study recommends that the ministry of education at the county level should facilitate construction of libraries in the primary schools so as to improve and enhance teaching and learning of children beginning from the preprimary to senior classes. In addition, the facilitation will boost learning and power of implementing and enacting the policies set for improving learning and teaching of learners.
School Inclusion in the Framework of the New Legal Regulations in Chile

Today, the link between concepts of education and diversity are far away in schools in Chile, and even more so in the country's educational policies, which only interests the concept of inclusion as a more segregating than inclusive concept. Three years after it was promulgated by President Michelle Bachelet, on Tuesday, March 1 of this year, the School Inclusion Law begins to be officially applied. Doubts, criticisms and marked differences persist from different sectors towards the new regulations that in principle intends to end the profit, selection and co-payment in subsidized private education establishments and not to the integration and inclusion of students with SEN as a focus principal.

The European Union had the opportunity to play a greater role in international affairs after the Cold War. Relying on its historical experiences and based on liberal approaches, this institution has tried to help a large number of struggling communities to fight extremism and achieve peace. Afghanistan, as a perfect example of a crisis-ridden, conflict-ridden, bankrupt state, has posed one of the most important security issues to the international community over the past twenty years. The European Union, along with other international actors, after the fall of the Taliban government in Afghanistan, tried to learn the principles and concepts of liberal peace theory and provide various financial, military, technical and ... assistance to the country towards peace. Guide and erase the roots of the conflict in this country. The main aim of this research paper is to State the relations of Afghanistan and the European Union from 2001 to 2019, from the Perspective of the EU mission and the hypothesis is the strategy that the EU follows in terms of the Cooperation’s, The relationship between both parties was examined from the point of view of the influential notions such as political, security, economics, Cooperation and history. To answer the question: "Given the 20-year presence of the European Union in Afghanistan with the aim of establishing peace in this country, to what extent has this institution succeeded in achieving its goals?" The present article states that after more than two decade of EU..........

Background: Multiple pregnancies constitute an important portion of high-risk pregnancies and are a matter of grave concern to obstetricians and pediatricians owing to maternal and perinatal morbidity and mortality associated with it. We have very little research-based information regarding the maternal and perinatal outcomes of twin pregnancy. Aim of the study: The aim of this present study was to evaluate the maternal and perinatal outcomes of twin pregnancy. Methods: This cross-sectional observational study was conducted under the Department of Obstetrics & Gynaecology at The Center for Woman and Child Health (CWCH), Dhaka, Bangladesh during the period from January 2018 to December 2020. Fifty-two (52) women of twin pregnancy were selected as study participants purposively. Independent variables of interest were gestational age, preterm delivery, and mode of delivery. Dependent variables of interest were preeclampsia, premature rupture of membranes, postpartum hemorrhage, birth weight, perinatal morbidity, and mortality. Statistical analysis of the results was obtained by using window-based computer Statistical Packages for Social Sciences (SPSS-22). Results: In this study, the total number of vaginal delivery was 50 (1st Twin-26 & 2nd Twin- 24: 48%) and the total number of LSCS was 54 (1st Twin-26 & 2nd Twin 28: 52%). Among total participants, antepartum complication anemia, H gravidarum, HTN (PIH/PE/Eclampsia), polyhydramnios, PROM, gestational DM and APH were found in 48.07%, 7.69%, 28.84%, 5.76%, 9.62%, 3.84%, and 1.92% patients respectively. Among 52 twin pregnancies, the most common intrapartum complication was preterm delivery 59.61% (n=31). Preterm LSCS was 46.15% and preterm vaginal delivery was 13.46%. We found term and preterm deliveries were 40.39% and 59.61% respectively. The most common neonatal complication was the low birth weight which was found in 84.6%. No maternal mortality in the study. Some patients had more than one complication. ..........

Background: Gallstones are the most common cause of emergency hospital admission for people with abdominal pain worldwide. In most of cases they don't cause any symptoms and no need to be treated. Material and methods: A prospective study conducted on 100 patients involving all diagnosed patients of cholelithiasis admitted and supposed to undergo Laparoscopic Cholecystectomy. The first fifty patients undergoing elective Laparoscopic Cholecystectomy will be given injection Ceftriaxone 1.5 gm i.v. after the test dose outside the operation theater in the wards and the antibiotics were continued for 2 days. The next fifty patients were given a single dose of injection Ceftriaxone 1.5 gm i.v. after the test dose just before the induction of anaesthesia. Results: Majority of the cases belongs to 35 patients were in 18-30 years age group, 86 (86%) were females. Our study shows that incidence of Cholelithiasis is more among females which is consistent with general population. Out of the 100 cases of elective Laparoscopic Cholecystectomy, drain were placed in 45 (45%) patients, and no drain required in 55 (55%) of patients. Out of 50 patients of single dose antimicrobial group 32 (64%) developed post-operative fever, 3 patients (6%) had post-operative raised WBC count and 3 patients (6%) had post-operative surgical site infection. Out of 50 patients of multidose antimicrobial group 31 (62%) had post-operative fever, 2 patients (4%) had post-operative raised WBC count and 2 patients (4%) had post-surgical site infection. Conclusion: There is no statistical difference between single dose and multi dose antimicrobial treatment in terms of surgical site infections and post-operative hospital stay.

D-galactose is widely used as an inducing reagent for animal models of aging. The aging model by D-galactose induction has similarities with natural old. In this study, we described the effect of D-galactose administration in rats against their body weight. Thirty healthy male rats aged 2 months were divided into 2 groups. Control group was treated with aqua sterile as placebo, while D-galactose group was treated with 3 mg/kg BW of D-Galactose orally every day for 6 weeks. The rats in both groups were measured using digital weigher every week. The data were analyzed descriptively for the average of body weight (g) each week and statistically for the average of weight gain (%) after 6 weeks using t-test. The average of body weight in control group from week-0 until week-6 were 119± 16.24; 144± 20.24; 160± 27.37; 170± 29.08; 179± 32.79; 197± 32.37; and 208± 32.07, while in D-galactose group were 129± 13.92; 151± 15.94; 164± 24.63; 173± 25.37; 182± 27.15; 192± 25.55; and 197± 25.55. Statistical analysis using t-test showed that there was a significant difference of average weight gain in both groups (p<0.05). The average of weight gain in control group and D-galactose group was 75.59%±21.19% and 53.76%±21.79%, respectively. D-galactose could decrease the weight gain in rat model of aging.
Energy Prediction Model of PSO-BP Neural Network Three-dimensional Clusters based on Atomic Coordinates
Authors: Zhang Zhan , Huang Rong , Li Zhenglong
Published: June 2022

Energy prediction for different cluster structures is the basis for finding and predicting the global optimal structure of clusters. The current methods for predicting the energy of the ground state structures of different clusters include theoretical prediction methods and optimized simplified potential energy function methods. The accuracy of the theoretical prediction method is high, but its calculation amount is too large. Therefore, this paper proposes a PSO-BP neural network three-dimensional cluster energy prediction model based on atomic coordinates, and uses different types of Euclidean distances between atoms as input variables, and the energy of clusters with different structures as output variables. Select gold cluster Au20 and boron cluster B45-part of the sample data as the training set to build the model, and predict the rest of the samples, and finally get: the prediction accuracy of the PSO-BP neural network model is higher than that of the traditional BP neural network model. The cluster energy prediction model is feasible.
