Analysis of shallow depth profiles of titanium nitride and N-implanted titanium by GD-OES: the ‘hydrogen effect’ after the discharge startup and a correction thereof

Disturbing effects, affecting depth profile analysis by GD-OES of the near-surface layers of Ti–N matrices, are described and attributed to the desorption of atmospheric gases including moisture from the inner surfaces of the glow discharge source. These effects are viewed as a perturbation, affecting sample atomization and excitation of analyte species. A formalism is proposed to correct for this perturbation when evaluating experimental data. The emission intensity of the hydrogen line at 121.567 nm is used as a variable expressing the magnitude of the perturbation. The modified quantification procedure is applied in the analysis of a series of titanium samples implanted with nitrogen.
Transformational Leadership Survey

Several previous research have described transformational leadership as successful leadership that led higher education to implement changes for the better. However, a more comprehensive survey on the implementation of transformational leadership in higher education has not been conducted. This research aims at observing a transformational leadership style with the model 4I, namely idealized influence, intellectual stimulation, individual consideration, and inspirational motivation, which is applied to higher education comprehensively. A survey method with questionnaires taken from lecturers working at higher education in Indonesia was used in this research. The findings revealed that attention given to individuals and reducing penalty towards any mistakes by subordinates must be given more attention so that the application of complete combination between one dimension and other dimensions and each indicator of transformational leadership must be carried out. This research is expected to have implications for the effectiveness of higher education leadership, and be used as a reference by higher education leaders in choosing a leadership style.
Halogen Adsorption and Reaction with Bi2(Se,Te)3 and Bi/Bi2(Se,Te)3

Bi$_2$Se$_3$ and Bi$_2$Te$_3$, and these same surfaces covered with Bi films, are exposed to Br$_2$ and Cl$_2$ in ultra-high vacuum. Low energy electron diffraction (LEED) and low energy ion scattering (LEIS) are used to investigate the surface composition before and after halogen exposure. It is found that Br$_2$ weakly chemisorbs to the Se- or Te-terminated clean surfaces and light annealing removes the adsorbates restoring the intact surfaces. In contrast, halogens dissociatively adsorb onto surfaces covered with an additional bilayer of Bi, having a p-doping effect. Annealing these halogen-covered surfaces at 130{\deg}C causes Bi atoms to be chemically etched away and the surface reverts to a Se- or Te-termination. This work shows how halogen adsorption and reaction can be used to modify the surface termination of such materials.
4-Cyclohexyl-1-(2-methoxybenzoyl)thiosemicarbazide with an unknown solvent

In the title compound, C15H21N3O2S, a short intra­molecular N—H⋯O hydrogen bond generates an S(6) ring. The mol­ecule is twisted with a dihedral angle between the benzene ring and the mean plane of the cyclo­hexyl ring being 58.90 (6)°. In the crystal, inversion dimers are formed with each molecule linked to the other by two N—H(H)⋯O hydrogen bonds to the same acceptor, generating R21(6) loops. A region of disordered electron density was corrected for using the SQUEEZE routine in PLATON [Spek (2015). Acta Cryst. C71, 9–18]. The given chemical formula and other crystal data do not take into account the unknown solvent molecule(s).
Continuous effectiveness and safety after a hospital‐wide switch to adalimumab biosimilar: An observational study in rheumatoid arthritis patients

The objective of this study was to examine the maintenance of effect and safety after a hospital‐wide switch for economic reasons from adalimumab originator Humira® to biosimilar Amgevita® in real‐world rheumatoid arthritis (RA) patients and patient satisfaction with the switch. We conducted a single‐center retrospective observational study of RA patients on the course of their disease activity (DAS28, ESR, and CRP), health‐related quality of life (SF‐36), and functional disability (HAQ‐DI) before and up to 1 year after the switch, supplemented with a cross‐sectional survey on satisfaction and experienced side effects approximately 18 months after the switch. Treatment outcomes were analyzed with linear mixed modeling and generalized estimating equations. Of 52 RA patients sufficient data were available. Disease activity levels, the proportion of patients in remission, and SF‐36 and HAQ‐DI scores did not significantly change from before the switch. Overall, patients were satisfied with the switch. Three patients (7.9%) stopped the biosimilar due to side effects. In conclusion, switching to the adalimumab biosimilar did not result in increased disease activity or worse patient‐reported outcomes. Also, there was no apparent evidence of increased side effects. Patients themselves were mostly satisfied with the switching experience.
A GENERALIZED APPROACH TO GENERATE THE COMPONENT MODELS FOR MULTI-OBJECTIVE OPTIMIZATION IN POWER ELECTRONIC APPLICATIONS

Multi-objective optimization (MOO) in the area of power electric applications requires complete and reliable component models. This contribution presents a simple and standardized method to generate the component models. After a short introduction, the stepwise approach is presented using the example ‘dc-link capacitor’. The problem of reliable component prices at low minimum order quantities (MOQ) is addressed and a concept called ‘linear-price estimation’ is introduced to solve the problem. Results of the models are shown and discussed. It is shown that small errors between training data and the models can be achieved for the cost, size and efficiency models with the approach. Finally, the approach is classified in the research field of MOO and it is briefly outlined that the approach can also be applied to other components (e.g. semiconductors).
Development of Wind IPMSG Based Bipolar DC Microgrids

This paper presents the development of a wind Interior Permanent-Magnet Synchronous Generator (IPMSG) based bipolar DC microgrids along with various switch-mode rectifiers. Firstly, the wind IPMSG is established and adequately controlled to possess satisfactory generating characteristics during different driven speeds and loads. Later, the boost switch-mode rectifier (SMR) based bipolar DC bus is established. Further, three-phase single-switch (3P1SW) boost SMR, three-phase two-switch (3P2SW) three-level boost SMR, and a three-phase three-switch (3P3SW) Vienna SMR are comparatively evaluated. Along with the proposed robust voltage and current controls, a well-regulated microgrid DC-bus voltage is established. Moreover, the voltage balancing control is proposed to minimize the imbalance in the bipolar DC-bus voltage. For the wind IPMSG having Vienna SMR, the commutation angle setting is adjusted to use the reluctance power component effectively.
Cobalt−Tetracyanoquinodimethane Monolayer as Efficient Bi-Functional Single Atom Electrocatalyst: A First Principles Investigation

A bi-functional electrocatalyst is a stable and catalytically active material for both oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), the development of which is highly challenging, although essential for application in fuel cells. Herein, the first principle based density functional theory (DFT) computations have been carried out to investigate a series of transition metal-tetracyanoquinodimethane (TM-TCNQ: TM = Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Ru, Rh, Pd) monolayer for bi-functional single atom electrocatalyst towards ORR and OER. Amongst various first transition metal row based TCNQ substrates, Cobalt-TCNQ (Co-TCNQ) monolayer was predicted to exhibit best bi-functional catalytic activity. At equilibrium potential (1.23 V, vs RHE), the free energy portraits of Co-TCNQ monolayer for OER in acidic or alkaline media are not completely downhill, measuring an excess potential of 0.6 V, equal to the overpotential, which is needed to be supplied externally to promote the OER activity. On the other hand, an onset potentials of 0.34 V (vs RHE) in acidic media are measured for ORR to proceed. The promising catalytic activity of two dimensional Co-TCNQ monolayer towards ORR and OER as revealed by DFT investigations has been explained in terms of density of states and Bader charge analysis.
Flexible and Stretchable Biobatteries: Monolithic Integration of Membrane‐Free Microbial Fuel Cells in a Single Textile Layer

The fabrication and performance of a flexible and stretchable microbial fuel cell (MFC) monolithically integrated into a single sheet of textile substrate are reported. The single‐layer textile MFC uses Pseudomonas aeruginosa (PAO1) as a biocatalyst to produce a maximum power of 6.4 µW cm−2 and current density of 52 µA cm−2, which are substantially higher than previous textile‐MFCs and are similar to other flexible paper‐based MFCs. The textile MFC demonstrates a stable performance with repeated stretching and twisting cycles. The membrane‐less single‐chamber configuration drastically simplifies the fabrication and improves the performance of the MFC. A conductive and hydrophilic anode in a 3D fabric microchamber maximizes bacterial electricity generation from a liquid environment and a silver oxide/silver solid‐state cathode reduces cathodic overpotential for fast catalytic reaction. A simple batch fabrication approach simultaneously constructs 35 individual devices, which will revolutionize the mass production of textile MFCs. This stretchable and twistable power device printed directly onto a single textile substrate can establish a standardized platform for textile‐based biobatteries and will be potentially integrated into wearable electronics in the future.
“Nobody complies with it anyway. Well yes, those who do not smoke” – Combining methods for understanding adolescents’ approach to a smoke-free agreement.

Background: Non-smoking agreements has shown effective in preventing smoking among adolescents. However, to date, this is the first study to explore: 1) if adolescents who do or do not sign have specific characteristics, 2) adolescents’ attitudes towards signing and committing to these smoke-free agreements (SFA). Methods: This is explored by combining questionnaire and focus group data. The questionnaire data is gathered as part of the evaluation of X:IT study II; a smoking preventive intervention targeting adolescents in 7 th -9 th grade. In this paper data from second follow (8 th grade) up is used. Eight focus groups (N=43) were conducted with the adolescents in 8 th grade at two Danish secondary schools. Inspired by theory integration we draw from resistance theory to combine the results from the methods. Results: The questionnaire data showed that adolescents who were partaking in smoking or smoking-related behavior including current or ever smoked as well as have ever tried hash, snuff or electronic cigarettes to a less degree signed a SFA. Focus group analysis showed that even though the adolescents at the two schools emphasized a lack of attention to the SFA, the lack of attention was ascribed to different approaches to smoking and the SFA. In general, adolescents at one of the schools had no intention of smoking and thus willingly signed and committed. Whereas, adolescents at the other school expressed a greater resistance to signing as well as committing to the SFA. Instead, what seemed important for the adolescents at this school was a desire to act freely and appear with no strains, including possibility to smoke, which the SFA seemingly threated. Conclusion: Although non-smoking agreements, implemented in the school setting, have been effective in decreasing smoking among adolescents in other studies, our results suggest that the SFA may appeal differently to adolescents according to certain characteristics, while getting overall very little attention.
Investigation on the Effect of Current Density on Porous GaN Fabricated by UV-assisted Electrochemical Etching

84 Abstract—This paper reported the anodization of porous GaN by UV-assisted electrochemical etching with a usage of lower power of UV light in an electrolyte that consist of 4% potassium hydroxide (KOH) with a variations of applied current density (20, 30 and 40 mA/cm). Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-Ray (EDX), Atomic Force Microscopy (AFM) and X-ray Diffraction (XRD) were used to characterize the morphological and structural characteristics while the Raman spectroscopy was used to identify the optical properties of the prepared porous GaN. Top view images from the FESEM demonstrated that the pore uniformity and porosity are affected significantly by the current density. The porous GaN sample etched with 40 mA/cm produces a higher porosity and larger diameter pore structure compared to other porous GaN sample. This shows that the morphology and structural characteristic of porous GaN are increase with the increase of current density. The EDX result revealed there is no contamination occur, as only significant Ga and N atom presence in all samples. The AFM verified that the surface roughness and the pore depth are increased as current density increased. There were relatively large variations of the peak intensities for 2Thetascan patterns as exposed by XRD. Raman intensity found to be enhanced with the increase in current density and among the porous GaN sample, the peak for sample fabricated with 30 mA/cm and 40 mA/cm was observed to be slightly shifted to lower frequency.

Highly stable ultrathin TiO2 based resistive random access memory with low operation voltage

In this article, we display the fabrication methods and characterizations of the ITO/TiO2/Pt resistive random access memory (RRAM). By transmission electron microscopy (TEM) analysis, the fabricated TiO2 thin film of our RRAM device was confirmed to be amorphous instead of other common crystal direction. The RRAM here shows bipolar resistive switching characteristic for over a hundred times switching cycles with a resistance ratio (RHRS/RLRS) of more than 1 order and high stable retention characteristic for over 104 seconds with a resistance ratio (RHRS/RLRS) of around 2 orders. We found that conduction mechanism was dominated only by ohmic conduction in both set and reset procedure. The set and reset voltage of the ITO/amorphous TiO2 (a–TiO2)/Pt of this article were around 0.6 and –0.5 V, make it state–of–the–art in low operation voltage application. © The Author(s) 2018.

Spectral Anomaly Detection Based on Dictionary Learning for Sea Surfaces

Anomalies in remote sensing images are generally reflected in two aspects of spatial and spectral ones, as for the anomaly detection of sea surface using multispectral or hyperspectral images, spectral information is more important. To this end, a novel spectral anomaly detection method based on dictionary optimization is proposed in this letter. More specifically, the normal scene is first defined to distinguish the anomaly. Then, without any assumption about the distribution of anomaly, a spectral dictionary is formulated and derived theoretically with optimization to express the normal scenes. Using the sparse and low-rank constraints, the alternating direction method of multiplier (ADMM) is employed to solve the above optimization in the spectral domain. Finally, for a given sea-surface image to be detected, the error matrix that cannot be fully expressed by the optimized spectral dictionary is regarded as anomalies. It shows certain generality for various kinds of spectral anomalies on the sea surface. Taking multispectral images obtained by the HY-1C satellite as an example, comparisons with related state-of-the-art methods demonstrate that our proposed method achieves the best anomaly detection performance not only for oil-spill pollution but also for algae pollution.
Serum free fatty acid levels and insulin resistance in patients undergoing one-anastomosis gastric bypass

Introduction One anastomosis gastric bypass (OAGB) leads to improvement in glucose homeostasis; however, the mechanism of this beneficial effect is not fully understood. Increased serum free fatty acid (FFA) concentrations in obese subjects contribute to the development of insulin resistance and type 2 diabetes. Aim The authors hypothesized that improvement in glucose homeostasis after OAGB may be associated with a decrease in FFA concentration. Material and methods Serum FFA levels were measured by gas chromatography-mass spectrometry before and 3 months after OAGB and, for comparison, in patients who underwent laparoscopic sleeve gastrectomy (LSG). Serum insulin was assayed by immunoenzymatic method, and other parameters by standard laboratory methods. Results OAGB resulted in a large decrease in FFA levels and great improvement in insulin sensitivity. These effects in patients after LSG were less prominent. Conclusions Results suggest that decreased serum FFA levels after OAGB contribute to resolution of insulin sensitivity after this type of bariatric surgery.
