The Strength of Nesterov's Extrapolation2019
Authors: Tao Qing
Published: January 2020

The extrapolation strategy raised by Nesterov, which can accelerate the convergence rate of gradient descent methods by orders of magnitude when dealing with smooth convex objective, has led to tremendous success in training machine learning tasks. In this paper, we theoretically study its strength in the convergence of individual iterates of general non-smooth convex optimization problems, which we name \textit{individual convergence}. We prove that Nesterov's extrapolation is capable of making the individual convergence of projected gradient methods optimal for general convex problems, which is now a challenging problem in the machine learning community. In light of this consideration, a simple modification of the gradient operation suffices to achieve optimal individual convergence for strongly convex problems, which can be regarded as making an interesting step towards the open question about SGD posed by Shamir \cite{shamir2012open}. Furthermore, the derived algorithms are extended to solve regularized non-smooth learning problems in stochastic settings. {\color{blue}They can serve as an alternative to the most basic SGD especially in coping with machine learning problems, where an individual output is needed to guarantee the regularization structure while keeping an optimal rate of convergence.} Typically, our method is applicable as an efficient tool for solving large-scale $l_1$-regularized hinge-loss learning problems. Several real experiments demonstrate that the derived algorithms not only achieve optimal individual convergence rates but also guarantee better sparsity than the averaged solution.
Permanent Magnet Synchronous Machine Temperature Estimation using Low-Order Lumped-Parameter Thermal Network with Extended Iron Loss Model
Authors: Gedlu Emebet Gebeyehu , Wallscheid Oliver , Böcker Joachim
Published: January 2020

Since temperature rise in electric machines is mainly
due to power losses during electro-mechanical power conversion, temperature estimation is highly attached to power loss modelling. In this contribution, an extended iron loss model is introduced with a direct identification methodology in the context of temperature estimation. The iron loss model is implemented as part of a fourth-order lumped-parameter thermal network (LPTN), which is parametrised using empirical measurements and global identification. Once parameters are identified using training data, the LPTN model is validated using three unseen profiles cross-validation. Satisfactory estimation is achieved with the average mean squared error of 2.1 K2 and the error bias close to zero.

Published: January 2020

En el suelo contaminado en alta concentración de aceite residual automotriz (ARA) causa pérdida de su fertilidad. Una solución es la biorremediación (BR) por doble y secuencial bioestimulación (BS) y posterior fitorremediación (FR) con Sorghum vulgare y Bacillus cereus/Burkholderia cepacia o bacterias promotoras de crecimiento vegetal (BPCV) para reducir el ARA remanente. Los objetivos de este trabajo fueron: a) biorremediar un suelo contaminado con 75000 ppm de ARA por doble y secuencial bioestimulación, y posterior b) fitorremediación con S. vulgare y las BPCV. El suelo contaminado con ARA se biorremedio por BS primero con solución mineral (SM), una segunda BS con Phaseolus vulgaris y BPCV incorporada como abono verde (AV), después por fitorremediación con S. vulgare y las BPCV para minimizar el ARA. Los resultados indicaron que la biorremediación del suelo por doble y secuencial BS: con SM el ARA decreció a 32500 ppm/30 días y con P. vulgaris; lo disminuyo hasta 10100 ppm/90 días. Su fitorremediación para minimizar el ARA remanente con S. vulgare y BPCV a floración lo redujo de 2500 ppm a 800 ppm. Ello apoya que biorestaurar un suelo impactado con elevada concentración de ARA; la mejor es la integración de la BR/FR, que su aplicación por separado.

Authors: Shramko Oleksandr
Published: January 2020

Purpose. The aim of the article is determination of peculiarities of forensic evaluation expertise and its classification on the basis of the analysis of existing scientific views and provisions of the current legislation of Ukraine.

Methodology of research. The theoretical and methodological basis of the study are the fundamental provisions of forensic evaluation expertise, as well as scientific works of domestic scientists, devoted to the problems of classification and conduct of forensic evaluation expertise in Ukraine. Modern research methods are used to achieve this goal: systematic analysis – in the study of theoretical and methodological foundations of forensic evaluation expertise; abstract and logical – to clarify the essence of the basic concepts, definitions and categories of forensic evaluation expertise. We also used such research methods as a monographic and graphical method of presenting information.

Findings. It is determined that in modern conditions forensic expertise is a complex multifaceted activity, which is carried out in expert institutions by relevant highly qualified specialists, which performs multidimensional activity having specific characteristics related to organizational, cognitive, criminal procedural and other parties. It has been established that forensic activities perform an information-providing function to form the conditions for conducting a qualified, objective forensic expertise using scientific methods of cognition. The purpose of the examination is to provide answers to the questions that require special knowledge. The subject matter of the examination is the disputed subject, the subject matter – facts and data related to the question under investigation and which require the expert's judgment. It is determined that the expert's study is formalized by expert opinion, which is evidence of the presence or absence of facts and other data that have been the subject of dispute. The analysis of the legislative framework for the regulation of the national judicial evaluation expertise has been carried out.

Originality. The characteristic features of forensic evaluation expertise that determine their authenticity are highlighted in the article, in particular: the legal concept of examination; “expertise” as an extracurricular check; “expertise” as a procedural inquiry and “independent expertise” as a non-procedural study. The classification and methods used in forensic evaluation are substantiated and determined. Various approaches to the classification of expertise in domestic practice have been generalized and highlighted.

Practical value. The obtained proposals can be used to improve the current system of forensic evaluation development, which determine the need for organizational, procedural and legal solutions to a number of problematic situations.

Published: January 2020

The paper aims to present research results obtained at the study of equilibrium and kinetics of U(VI)aq sorption on in situ generated Fe2O3 x nH2O from model solutions. The studied systems represent U(VI) solutions with CU(VI) = 5-30 mg�L-1 for which maximum U(VI) removal efficiencies (%RU(VI) = 95.98) on in situ generated Fe2O3��nH2O were obtained in the following working conditions: pH = 8.75, tcontact = 30 min, [U(VI)] : [Fe(III)] =1:75 and stirring rate 250 RPM. The Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherm models were used to study U(VI) sorption equilibrium. Langmuir isotherm with the correlation coefficient R2 (0.9808) suggests that it involves physical interactions. Freundlich (R2 = 0.8349) and Temkin (R2 = 0.8715) models describe well the sorption process suggesting that there also exists a chemical component, complexing and/or co-precipitation. The kinetic modelling according to the pseudo-first and pseudo-second order models, respectively has demonstrated that the U(VI) sorption equilibrium follows the pseudo-second order equation suggesting a chemical component of the process.
Crosstalk between Oxidative Stress, Chronic Inflammation and Disease Progression in Essential Thrombocythemia
Authors: Gaman Amelia Maria , Moisa Cornel , Diaconu Camelia Cristina , Gaman Mihnea Alexandru
Published: January 2020

Essential thrombocythemia (ET) is a Philadelphia-negative chronic myeloproliferative neoplasm characterized by acquired somatic mutations: JAK2, CALR or MPL. It is associated with low-grade chronic inflammation, oxidative stress, overproduction of reactive oxygen species (ROS) and antioxidant deficiency. In ET, chronic inflammation and oxidative stress contribute to the genomic instability, the clonal evolution to myelofibrosis and the leukemic transformation. We evaluated ROS levels and the total antioxidant capacity (TAC) in 62 ET patients and investigated the relationship between ROS, TAC, chronic inflammation, leukocytosis, JAK2V617F mutation, and disease progression to myelofibrosis or leukemic transformation. We observed increased levels of ROS and inflammation markers and a decreased TAC in ET patients vs. controls. The acute myeloid leukaemia transformation associated increased levels of oxidative stress and inflammation markers and increased leukocyte counts, while myelofibrosis progression associated an increase in ROS and serum ferritin.

Published: January 2020

Coenzyme Q10 has a powerful antioxidant effect because it protects cells against free radicals and plays an important role in metabolism. Although controversial some preliminary evidence suggests that Coenzyme Q10 can help prevent or treat treatment of diseases of the cardiovascular and musculoskeletal systems and liver problems. Age increase and medical conditions are associated with lower Coenzyme Q10. There are evidences that diet supplementation with supplements containing Coenzyme Q10 may be beneficial. This paper aims to develop an HPLC method for identifying and dosing Ubidecarenone in food supplements. Using this technique, several supplements containing varying Ubidecarenone, ranging from 76 to 103% of the stated amount per dosage form were tested.

Published: January 2020

Salt intake is one of the important predictors of hypertension, a widespread chronic disease among adults. Much remains to be known about its causes, especially in the Romanian context, where there is a scarcity of analyses on this particular topic. Its predictors are relevant for public policy in order to evaluate what strategy should be adopted given actual levels of salt intake and the way people think about their levels of salt intake. Our analyses focus on actual and perceived salt intake. Data for this analysis come from the SEPHAR project, gathered in 2016 (wave 3), a nationally representative sample of Romanians. After noting a major discrepancy between perceived and actual levels of salt intake, we used two regressions with actual and perceived salt intake as dependent variables and three types of factors as independent variables: socio-demographic (age, gender, region, type of locality, education), lifestyle (fat diet, alcohol consumption, active lifestyle, and smoking) and related diseases (obesity and diabetes). Results show Romanians have similar levels of salt intake perceptions independently of the characteristics considered, except fat diet and diabetes, and similar levels of actual salt intake except age and gender, even though previous research shows that there are differences between individuals across these characteristics when it comes to considering hypertension as a dependent variable. We conclude by noting policy interventions regarding salt intake based on the results of this research, especially the need to update the current Romanian TV campaign to reduce salt intake or similar campaigns from other countries.

The aim of the study is to quantify ventricular interactions by comparing tissue and spectral systolic echocardiographic parameters to allow the early identification of ventricular dysfunction. Clinical, paraclinical, electrocardiographic and echocardiographic evaluations were performed. Right ventricular hypertrophy was diagnosed in the M mode subcostal echocardiographic section. RV hypertrophy was defined by a right ventricular free wall thickness of ] 5 mm in diastole. We assessed the following RV and LV tissue and spectral systolic indices: apical systolic excursion of the lateral mitral ring (MAPSE), apical systolic excursion of the lateral tricuspid ring (TAPSE), left (Svs) and right (Svd) ventricular tissue systolic velocities, and RV and LV ejection times. We calculated the following to assess systolic ventricular interdependence: MAPSE/TAPSE, the normal value of which was considered as 0.66 � 0.14, and Svs/Svd, the normal value of which was considered as 0.76 � 0.21. The study group was compared to a control group with the same clinical features but without ventricular hypertrophy. Twenty-one patients were included in the study: 13 men (62%) and eight women (38%) with a mean age of 56 � 3.8 years. We compared the values between the study group and control group, with the following results: TAPSE = 20.4 � 0.9 vs. 24.1 � 0.76 and MAPSE/TAPSE = 0.74 � 0.06 vs. 0.75 � 0.04. MAPSE was comparable between the groups. Svs was comparable between the groups (0.09 � 0.01 vs. 0.12 � 0.02), whereas Svd was different between the groups (0.11 � 0.03 vs 0.16 � 0.03). Svs/Svd was 0.81 � 0.05 in the study group and 0.75 � 0.08 in the control group. LV ejection time was comparable between the two groups (299.8 � 23.6 ms vs. 303.3 � 28 ms), whereas, RV ejection time differed between the groups (275 � 17 ms vs. 245.5 � 28.5). Changes in TAPSE and MAPSE/TAPSE, in addition to Svd and Svs/Svd, are related to right ventricular dysfunction and suggest pathological changes in the interdependence mechanism of the ventricles in patients with RV hypertrophy. In addition, RV free wall thickness was strongly correlated with ventricular interdependence parameters, with the exception of MAPSE. Assessing these parameters and proportions in clinical practice will facilitate the early detection and appropriate treatment of right ventricular dysfunction.

Authors: Pascu Emilia Georgiana , Gaman Mihnea Alexandru , Moisa Cornel , Gaman Amelia Maria
Published: January 2020

Chronic myeloid leukemia (CML) is a chronic myeloproliferative neoplasm characterized by the presence of the Philadelphia chromosome. Oxidative stress is involved in CML etiopathogenesis and disease progression, as well as the response to tyrosine kinase inhibitors (TKI) treatment. We evaluated oxidative stress levels in 47 CML patients vs. controls. The total antioxidant capacity (TAC) was measured using a FLUOstar Omega microplate reader (reagents from Sigma-Aldrich). Cellular reactive oxygen species (ROS) were evaluated using a CyFlow SPACE Sysmex flow-cytometer (reagents from Abcam). Oxidative stress levels were higher in CML patients vs. controls. The maximum TAC value and the minimum ROS value were recorded in CML patients with a BCR-ABL1 transcript value of 0.1-1%, suggesting that the production of plasma antioxidants progressively increases as a compensatory mechanism in CML patients undergoing TKI treatment in order to annihilate ROS. The pseudonormalization of the cell redox status observed in these patients could be an alarm signal prior to the development of resistance to TKI treatment or disease progression.

Published: January 2020

Artificial neural network ANN is an appropriate tool for predestining the different relationships across many scientific researches. Air emissions prediction is an effective method of securing public health by revealing the imminent danger of air pollutants. So far, the existing methods of air emissions concentration prediction became useless on long-term dependencies, and most neglect spatial correlations. In this study, an artificial neural network model, which also takes into account the spatial-temporal variable, is proposed for prediction of air emission. The ANN was used in order to take into account the historical data, auxiliary data such as environmental quality and weather conditions. Evaluation of the results revealed that the developed ANN model appears to be an appropriate tool in predicting environmental air emissions. The data were collected from 12 air quality-monitoring stations from a random county in Romania. The proposed model performed well and presented a relative error varies from 0 to 4.7%.

Published: January 2020

Amyloid-b (Ab) peptides are proteins associated with Alzheimer�s disease (AD), because the extracellular Ab deposits are the main cause of this disorder. The aggregation of Ab has been shown to depend on the interactions with metal ions, such as copper, zinc, aluminum or iron. The N-terminal sequence of Ab(1-42) or Ab(1-40) peptides, namely Ab(1-16) peptide fragment, is considered the metal binding site involved in AD neurodegeneration and amyloidogenesis. Therefore, we have investigated different peptide sequences to understand the role played by some amino acid residues in metal binding. In this paper, we report the chemical synthesis of Ab(9-16) peptide and its analogs by Fmoc/tBu strategy and the mass spectrometric evidence for metal ion binding to newly synthesized peptides. MALDI-ToF mass spectrometry proved to be a reliable tool to detect and identify the metal ion complexes of all peptides investigated with copper, iron and zinc ions.
Aspects on Rotational Cooling of Glyoxal Using Carrier Gases He and Ar
Authors: Duca Mariana D.
Published: January 2020

Molecular beam characterization performed for the carrier gases He and Ar reveals particularities in glyoxal fluorescence signal and beam rotational temperature related to the carrier gas. The dependence of the fluorescence signal on stagnation pressure at constant glyoxal partial pressure shows that the signal has a maximum that is higher for He than for Ar. The estimation of the effective nozzle diameter, deff, for different stagnation pressure values, p0, suggests that the decrease of the fluorescence intensity at higher p0 can be attributed, at least in part, to deff. On the other hand, Ar has the higher rotational cooling efficiency. Also the results show that the velocity slip (i.e. the difference between the mean velocities of the species in the binary mixture expansion) between glyoxal and carrier gas is not responsible for the difference in rotational cooling efficiencies of He and Ar.
