Controlled Formation of TiO2/MoS2 Core–Shell Heterostructures with Enhanced Visible‐Light Photocatalytic Activities

Most recently, much attention has been devoted to photocatalytic materials that may help to solve the global energy crisis and may provide environmental protection. Herein, novel cocatalysts based on few layered MoS2 and TiO2 nanomaterials have been designed by growing MoS2 nanosheets on the surface of TiO2 nanospheres through a facile hydrothermal method. The method allows the formation of TiO2/MoS2 core–shell heterostructures of uniform morphologies and stable structure and provides a good control over shell thickness. The mechanism that forms these heterostructures is discussed in detail. In addition, as cocatalyst, MoS2 nanosheets can enlarge the light harvesting window to include visible light and improve the photocatalytic ability of TiO2. Using Rhodamine B as the model, the resultant heterostructure is demonstrated to possess excellent and stable photocatalytic activity in the degradation of organic pollutants under visible light illumination. The TiO2/MoS2 heterostructures possess this catalytic activity due to their large surface area and their excellent interface for separating holes and electrons. Therefore, this novel heterostructure nanomaterials possess potential applications in water treatment, degradation of dye pollutants, and environmental cleaning.
The Study of a New Ceramic PZT Material

The PZT is modified by the introduction of doping agents in A-sites and/or B-sites of perovskite structure [1]. The principal role of dopants is generally improving the properties of these materials for their adaptation to specific applications, which is the purpose of this study. Our choice fell on the mixed oxide: acceptor and donor. Five compositions with varying dopants percentage were prepared by the conventional method of thermal synthesis of mixed-oxides. Pb1-0.04Sm0. 02Nd0.02[(Zr0.55,Ti0.45)1-2x,x(Y2/3,Mo1/3),x(Y2/3,Ni1/3)]O3 such that (x = 0.01, 0.03, 0.05, 0.07 and 0.1), are studied. All the samples were being sintered at a temperature ranging from 1100˚C to 1180˚C after being compacted in circular discs. The detailed structure was carried out for sintered specimens. The results of X-ray diffraction showed that all the ceramics specimens have a perovskite phase. The phase structure of Pb1-0.04Sm0. 02Nd0.02[(Zr0.55,Ti0.45)1-2x, x(Y2/3,Mo1/3),x(Y2/3,Ni1/3)]O3 ceramics was transformed from the tetragonal to the rhombohedral, with an increase in the ratio of Zr/Ti in system. The scanning Electron Microscopy (SEM) showed an increase of the mean grain size when the sintering temperature was increased. The lattice parameter measurements showed that tetragonal and rhombohedral unit cells of the phases depend on the sintering temperature.
PWM-Controlled Series Resonant Converter for Universal Electric Vehicle Charger

This article presents a pulsewidth modulation (PWM) controlled series resonant converter (SRC) for a universal EV charger. This article focuses on the boost mode of a SRC. By adapting two PWM boost switches with a full bridge rectifier, it is possible for a SRC to cover a very wide range of gain with a high and flat efficiency curve. As the output voltage increases, the secondary side rectifier of the proposed converter gradually converts from a full bridge rectifier to a voltage doubler rectifier. Since the switching frequency is fixed to the resonant frequency in boost mode, the proposed converter naturally achieves “two peak efficiency points” with full bridge and voltage doubler rectifiers. Two peak efficiency points limit the efficiency drop over a wide range of gain, and that is the reason the proposed converter achieves a high and flat efficiency curve. The effectiveness of the proposed converter and control has been verified on an 800 V input and 200–950 V/3.3 kW output prototype.
High-Gain Conical-Beam Planar Antenna for Millimeter-Wave Drone Applications

In this communication, a high-gain planar antenna with a conical beam (CB) is presented for millimeter-wave drone applications. The proposed antenna comprises a vertical monopole and a circular side reflectors. The high-gain CB is achieved by in-phase reflections from the planar annular-distributed side reflectors which is realized by a series of via walls using the printed-circuit-board (PCB) fabrication. The proposed structure was numerically and experimentally demonstrated. Full-wave analysis shows a 10 dB impedance bandwidth (BW) of 26.50–29.96 GHz, corresponding to 12.26% of the fractional BW, whereas the measured data account for 11.6% in the frequency range of 26.63–29.91 GHz. Meanwhile, a maximum peak gain of 8.51 dBi is observed at a beam-pointing angle of 22°, with a high radiation efficiency of 88.3%. Owing to these valuable features of high gain, good CB radiation performance, and simple planar structure, the proposed antenna is a promising candidate for millimeter-wave drone applications.
Complex genetic alterations contribute to rapid disease progression in an ALK rearrangement lung adenocarcinoma patient: a case report

Anaplastic lymphoma kinase tyrosine kinase inhibitors (ALK-TKIs) have been found to significantly improve the quality of life and survival in ALK-positive non-small cell lung cancer (NSCLC) patients. However, the duration of responses is limited by drug resistance. Genetic heterogeneity of ALK-positive tumors could potentially explain the differences in individual patient outcomes. We performed next-generation sequencing (NGS) on plasma samples, pleural effusion samples, and tissue re-biopsy obtained at various treatment milestones from an ALK rearrangement lung adenocarcinoma patient undergoing targeted therapy. The liver metastases of the EML4-ALK NSCLC patient presented rapid progression after 3.5 months of alectinib, while the other lesions showed good partial response. Targeted NGS identified the newly emerged MET amplification except for EML4-ALK in plasma ctDNA and liver lesions. Subsequently, a clinical benefit was achieved one month after the commencement of crizotinib, a dual ALK and MET inhibitor; however, the patient experienced disease progression another month later. Several rounds of ALK-TKI combination therapy were tried but failed. Concurrent genetic alterations, including loss-of-function mutations in FBXW7 and MLL3, may mainly contribute to poor prognosis in the patient. It highlighted the molecular profiling by using NGS can be useful in identifying the heterogeneity across lesions and the resistance mechanism of targeted treatments.
Finite-Time Event-Triggered Control for Semi-Markovian Switching Cyber-Physical Systems With FDI Attacks and Applications

This paper addresses the finite-time event-triggered control problem for nonlinear semi-Markovian switching cyber-physical systems (S-MSCPSs) under false data injection (FDI) attacks. Compared with the traditional time-triggered mechanism, the proposed event-triggered scheme (ETS) can effectively avoid network resource waste. Considering the network-induced delay in the modeling, a closed-loop system model with time delay is established in the unified framework. By the use of a mode-dependent piecewise Lyapunov-Krasovskii functional (LKF), stochastic finite-time stability (SFTS) criteria are established for the resultant closed-loop system. Then, some solvability conditions are established for the desired finite-time controller in light of a linear matrix inequality framework. Finally, an application example of vertical take-off and landing helicopter model (VTOLHM) is provided to demonstrate the effectiveness of the theoretical findings.
Type Of Marriage And Satisfaction In Light Of Socio - Economic Demographic Factors In Irbid Governorate - Jordan

The present study investigates endogamy and exogamy types. This study addresses the socio-economic and demographic factors. The convenient sample consisted of (291) participants from Irbid Governorate (in terms of availability). Frequencies, percentages and multiple regression were used to examine the role of the socio-economic and demographic factors dimensions in explaining the marital satisfaction. The aspects included are social, psychological and economic satisfaction, while the socio-demographic variables included are age, gender, education, income and period of marriage. The findings revealed that social satisfaction was the greatest, followed by psychological and economic satisfaction, respectively. The comparative means revealed that cases of endogamy are more satisfying than cases of exogamy. The multiple regression revealed that all of socio-economic factors dimensions have significant impact on the marital satisfaction among the participants except for gender.
Fasting and non-fasting lipid profile – A comparative study

Sedentary lifestyle and lack of physical activity predisposes to Hyperlipidaemia which is a modifiable risk factor for coronary artery disease. Deranged lipid profile is also seen in patients of hypertension and diabetes mellitus which are among most common non communicable diseases seen mainly in developed and some of developing countries. Dyslipidaemia depending upon the severity will be monitored by Lipid profile usually done in fasting state and based on differential derangement of lipid levels, treated accordingly. Most of the nations have switched on to non-fasting lipid profiles owing to its convenience and feasibility of testing and also probably considering the fact that body is exposed to non-fasting lipid levels for most time in 24 hours of the day. This pilot study tried to compare and study the fasting and non-fasting lipid profile components by doing an observational cross sectional study on 50 patients attending the Haasana Institute of Medical Sciences laboratory services, Haasana for regular health checkup. There was no statistically significant difference between total cholesterol, HDL cholesterol and LDL cholesterol in fasting and post prandial state whereas triglycerides and VLDL showed significant statistical difference with p value less than 0.05. Our study concludes that non fasting lipid profile is better both technically, operationally with better diagnostic and prognostic capability with respect to monitoring and treatment of dyslipidaemias as compared to fasting lipid profile.
Experimental Validation of Ultra-Precision Nanopositioning System

In this paper, the development of an ultra-precision XY nanopositioning stage is presented. For system structure, the actuator decoupled parallel compliant mechanism is designed to have the same dynamics in both x- and y-direction so that the coupling crosstalk between two axes can be minimized. Throughout the simulation validation of the deformed XY stage, the motion in the x-axis is not transferred to the motion in the y-axis. For the control structure, the simplified feedforward compensator provides the piezoelectric actuator to reduce the control effort of the system. A proportional double integral (PII) feedback controller is used to minimize the ramp-like disturbances so that the compensation of hysteretic nonlinearity and other disturbances can be effectively reduced. Moreover, the jerk-based optimal reference trajectory is designed so that 10 <inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> displacement at the constant speed with the smooth accel/deceleration period can be achieved. Having an experimental setup with several scenarios such as the constant speed of 10 <inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula>/s, 20 <inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula>/s, and 40 <inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula>/s, the tracking error can minimize within ± 2.5 nanometers, ± 3 nanometers, and ± 5 nanometers in the x-axis for each case. Moreover, the hysteresis variable is well compensated that the relationship between the reference trajectory and output displacement is almost linear. The proposed control strategies and implementation methods can operate the piezoelectric actuated XY stage system with the nanoscale precision motion for convenience.
Spectrophotometric Determination of Cefotaxime Sodium with Potassium Ferricyanide

A spectrophotometric method has been set up to determine cefotaxime sodium using potassium ferricyanide as the spectroscopic probe reagent.With the presence of potassium ferricyanide,the degradation product of cefotaxime sodium can reduce Fe3 + to Fe2 + at pH 3.0,which facilitate the formation of soluble Prussian Blue(KFeⅢ[FeⅡ(CN) 6]). The absorbance of soluble Prussian Blue is measured at its absorption maximum of 730 nm and the amount of cefotaxime sodium can be indirectly calculated.Under optimized conditions,a good linear relationship is obtained in the range of 0.040 ～ 24 mg/L of cefotaxime sodium.The linear regression equation is A = 0.05088 + 0. 2166ρ(mg/L) with linear correlation coefficient of 0.9986. The detection limit and relative standard deviation are 0.01 mg/L and 1.36%,respectively.Tthe apparent molar absorption coefficient of indirect determination of cefotaxime sodium is 2.3 × 105 L/(mol·cm). This method has been successfully applied to the determination of cefotaxime sodium in pharmaceutical and serum samples.
YI 2.1 Pulse Wave Velocity Estimation from the Radial PulseWaveform using Gaussian Process Regression: A Machine Learning Based Study

Objective and Motivation: Pulse wave velocity (PWV) is known to be associated with vascular ageing, a risk factor for cardiovascular disease (CVD) [1]. The European gold standard measurement of PWV requires an experienced operator to measure pulse waveforms at multiple sites, sometimes together with an electrocardiogram [2,3]. This study aims to estimate PWV from the radial pulse waveform using machine learning. Methods: Radial pulse waveforms and carotid-femoral PWVs were acquired in 3,082 unselected twins (https://twinsuk.ac.uk). 14 fiducial points on each pulse waveform were extracted using an in-house algorithm [4]. LASSO regression and principal component analysis (PCA) were used to identify the key features (timing and magnitude of the fiducial points) associated with PWV and exclude outliers. Finally, Gaussian process regression was used to estimate the PWV based on those key features only. Results: Results show that PWV can be estimated from the radial pulse waveform only with an overall root mean squared error (RMSE) of 1.82 m/s (Figure A). Most of the measured PWV values were within the 95% confidence interval range of the estimated PWV. The difference between measured and estimated PWV values increased with the increasing PWV. PWV estimation on a subgroup of twins with a healthy range of blood pressure and PWV values [5] was achieved with a RMSE of 1.38 m/s (Figure B). Conclusion: In this proof-of-concept study we have shown the possibility of estimating PWV from the radial pulse waveform using machine learning. This approach could make CVD
Machine Learning Classification of Port Scanning and DDoS Attacks: A Comparative Analysis

Cyber security is one of the major concerns of today’s connected world. For all the platforms of today’s communication technology such as wired, wireless, local and remote access, the hackers are present to corrupt the system functionalities, circumvent the security measures and steal sensitive information. Amongst many techniques of hackers, port scanning and Distributed Denial of Service (DDoS) attacks are very common. In this paper, the benefits of machine learning are taken into consideration for classification of port scanning and DDoS attacks in a mix of normal and attack traffic. Different machine learning algorithms are trained and tested on a recently published benchmark dataset (CICIDS2017) to identify the best performing algorithms on the data which contains more recent vectors of port scanning and DDoS attacks. The classification results show that all the variants of discriminant analysis and Support Vector Machine (SVM) provide good testing accuracy i.e. more than 90%. According to a subjective rating criterion mentioned in this paper, 9 algorithms from a set of machine learning experiments receive the highest rating (good) as they provide more than 85% classification (testing) accuracy out of 22 total algorithms. This comparative analysis is further extended to observe training performance of machine learning models through k-fold cross validation, Area Under Curve (AUC) analysis of the Receiver Operating Characteristic (ROC) curves, and dimensionality reduction using the Principal Component Analysis (PCA). To the best of our knowledge, a comprehensive comparison of various machine learning algorithms on CICIDS2017 dataset is found to be deficient for port scanning and DDoS attacks while considering such recent features of attack.
Computational Analysis of the Proton Transfer to the Secondary Quinone of Type II Photosynthetic Reaction Centers.

Quinones play an important role in industry and nature due to their ability to be doubly reduced and doubly protonated involving charged and radical i ntermediate states. In the study presented here, the energetics of all possible reduction and pr otonation reactions for two quinone systems, the benzoquinone and the duroquinone, are examine d by quantum chemical calculations. Correct relative energy levels of the uncharged reac tant and product state can be calculated easily. In contrast, the charged and radical states are difficult to describe correctly by quantum chemical methods. Our investigations lead to a prot ocol optimizing the coordinates of each states at the B3LYP/6-311++G(2d,2p) level of theory fo llowed by single point calculations at the CCSD/6-311G level. Solvent effects are modeled by the CPCM method. Based on the resulting electron distribution, partial charges are obta ined by popular methods as Mulliken, CHELPG, NPA and MK for Poisson-Boltzmann electrostatic cal culations. By this procedure we succeed in obtaining correct energy levels for the unchar ged, charged and radical states. The resulting reaction energies agree within 1.74 kcal/mol for the best charge model with the most reliable experimental results in literature on benzoquino ne. Interestingly, our calculations lead to pKa values for the protonation reaction of the semiquinone 3-4 u nits lower than in the experiment. This discrepancy can be explained, assuming that the experiments have measured the disproportionation reaction, which was discussed before a s a possible side reaction of the used setup. Thus, the protonation of the semiquinone is less like ly than proposed before. A complete and self-consistent description of the energetics of all mi crostates in a quinone system is given for the first time.

Results: Ethanol extract of P. macrocarpa leaves was able to prevent the decrease in the number of goblet cells (p<0.05). However, the administration of ethanol P. macrocarpa leaf extract could not reduce focal inflammation and angiogenesis in inflammation of the distal colon. Conclusion: Ethanol extract of the Mahkota Dewa leaves is able to prevent inflammation of the distal colon by preventing the decrease in the number of goblet cells.
KLİNİSYENLERİN KLİNİK LİDERLİK ALGILARININ ÖLÇÜLMESİNE YÖNELİK BİR ARAŞTIRMA

This study was conducted to determine the clinical leadership perceptions of healthcare professionals. The sample of the study consisted of 194 healthcare professionals working in a public hospital and agreeing to participate in the study. Clinical Leadership Scale was used in data collection. SPSS 21 statistics program was used to analyze the data obtained in the study. Since the data do not show a normal distribution, nonparametric tests were used in the analysis of the data. In the study, the average score obtained by the participants from the scale, which is a 3-point Likert type scale, was found to be 2.49 ± 0.29. In addition, it was determined that clinical leadership perception differs according to socio-demographic characteristics (duration of work in the institution, title, leadership and clinical leadership training) (p <0.05). In line with these results, it was recommended to add leadership and clinical leadership courses to the training curriculum of clinicians in order to further improve the clinical leadership characteristics of health professionals. In addition, training and studies related to leadership were suggested.
