Published: December 2023

Abstract
Objective Appliances used in preventive and interceptive orthodontics, which are often provided to correct or intercept a specific malocclusion or habit, may be detrimental. to a child's oral health. The objective of this study was to evaluate the effect of intra oral appliance wear on the plaque index, gingival index, bleeding on probing, and on levels of salivary Streptococcus mutans.
Materials and Methods A total of 60 children requiring any preventive or interceptive orthodontic treatment (appliance therapy) were randomly divided into two groups, as fixed orthodontic appliance group (n = 30) and removable appliance group (n = 30). Preoperative and post operative assessments of patients were done before and after wearing appliances. Assessment was done by determining oral hygiene status and microbiological evaluation of saliva for S. mutans count. S. mutans colonies were counted from saliva cultured on mitis-salivarius-bacitracin (MSB) agar.
Statistical Analysis Data that are continuous in nature were summarized as standard deviation and mean. For “within group” comparisons, paired t-tests were used to analyze the continuous data. For “between group” comparisons, unpaired t-tests and Fisher's exact test were used to analyze the continuous data.
Results Appliance treatment increases plaque and gingival indices. Plaque and gingival index changes 1 month after deployment of both fixed and removable appliances were essentially the same and statistically non-significant with p-values of 0.412 and 0.965. Bleeding on probing after insertion of both appliances was not statistically significant (p=0.423). S. mutans numbers increased following removable and fixed orthodontics. Fixed appliances had more S. mutans than removable appliances (p=0.014).
Conclusion The inherent levels of these microorganisms are related with plaque accumulation due to fixed or removable appliances. Increase in the level of plaque and microorganisms after fixed and removable appliance therapy can hamper optimum oral health and thus is a concern for pedodontists. During orthodontic therapy, cariogenic pathogens should be reviewed, and to prevent cariogenic pathogens from increasing and to maintain oral hygiene during orthodontic treatment, proper recall visits, patient and parent education, and regular fluoride application are essential.

Published: December 2023

Abstract
Background The adoption of technology in health care settings is often touted as an opportunity to improve patient safety. While some adverse events can be reduced by health information technologies, technology has also been implicated in or attributed to safety events. To date, most studies on this topic have focused on acute care settings.
Objectives To describe voluntarily reported safety events that involved health information technology in community and primary care settings in a large Canadian health care organization.
Methods Two years of safety events involving health information technology (2016–2018) were extracted from an online voluntary safety event reporting system. Events from primary and community care settings were categorized according to clinical setting, type of event, and level of harm. The Sittig and Singh sociotechnical system model was then used to identify the most prominent sociotechnical dimensions of each event.
Results Of 104 reported events, most (n = 85, 82%) indicated the event resulted in no harm. Public health had the highest number of reports (n = 45, 43%), whereas home health had the fewest (n = 7, 7%). Of the 182 sociotechnical concepts identified, many events (n = 61, 59%) mapped to more than one dimension. Personnel (n = 48, 46%), Workflow and Communication (n = 37, 36%), and Content (n = 30, 29%) were the most common. Personnel and Content together was the most common combination of dimensions.
Conclusion Most reported events featured both technical and social dimensions, suggesting that the nature of these events is multifaceted. Leveraging existing safety event reporting systems to screen for safety events involving health information technology, and applying a sociotechnical analytic framework can aid health organizations in identifying, responding to, and learning from reported events.

Published: December 2023

Metallic hydrogen (MH) has been predicted to be metastable, a high temperature superconductor, and a powerful rocket propellant. If true, MH could have an enormous impact on society. We have produced MH in a diamond anvil cell and studied its metastability. At a temperature of 5 K, the load on the metallic hydrogen was stepwise reduced until the pressure was essentially zero. While turning the load or pressure down, the sample evidently transformed to the molecular phase and escaped; the hole in the gasket containing the MH closed. We were unable to determine this value of the metastability pressure. Metallic hydrogen was not observed to be metastable at zero pressure, with no uncertainty.
Losers of representation: Gains and losses of globalisation as seen by workers in internationalised companies in the Netherlands
Authors: Hurenkamp Menno , Dekker Paul , Tonkens Evelien 
Published: December 2023

ABSTRACT
Dichotomisation between winners and losers is a prominent element of the debate on globalisation, with ordinary workers often considered losers. However, little is known about what workers make of globalisation, how they experience the phenomenon, and how they talk about it. We use a set of focus groups to explore meaning-making on the globalisation of the economy among lower-educated employees of Dutch internationalised firms. We find that they weigh up the pros and cons and proudly struggle with the consequences of globalisation. To the degree that they feel left behind, it is by politics and government. This suggests that dislike of globalisation is the result of negative experiences with politics, rather than the other way around.

Published: December 2023

Abstract
Room temperature ionic liquids (ILs) characterized by high dielectric loss factors and conductivity emerge as promising candidates for liquid-based metamaterial absorbers (LMMAs). In this work, the IL 1-ethyl-3-methyl-imidazolium dicyanamide was employed to construct an IL-based LMMA, leveraging a cross-architecture (C-A) design paradigm. Numerical analyses reveal that the C-A ILMMA achieves an absorption efficiency exceeding 90% within the frequency range of 7.5–57.8 GHz, translating to a relative absorption bandwidth of 153%. Moreover, the symmetrical configuration of the C-A ILMMA ensures its robust performance across a comprehensive range of polarization angles (0° to 90°), thereby underscoring its polarization insensitivity. Even with an increased incident angle of 60°, the C-A ILMMA sustains an absorption rate above 85% within the frequency intervals of 9.0–13.3 GHz and 24.7–60.0 GHz, highlighting its broad incident angle absorption capability. Owing to the superior thermal stability of the IL, the C-A ILMMA consistently maintains an absorption rate of over 90% across a temperature gradient from 20 °C to 100 °C. Mechanistic investigations reveal that the optimal absorption of the C-A ILMMA predominantly stems from dielectric polarization loss and the ionic current induced within the ILs. Subsequent experimental evaluations corroborate that the C-A ILMMA exhibits an absorptivity in excess of 90% over an ultra-broadband frequency spanning 10–40 GHz, aligning closely with numerical predictions. This IL-based C-A ILMMA not only augments the absorption bandwidth substantially but also enhances the adaptability of ILMMA in more rigorous environments, attributed to the commendable physicochemical properties of ILs.
Effect of the energy band bending on surface by Cu-poor layer of Cu(In, Ga)Se2-related photoelectrode for water splitting
Authors: Ueda Kana , Sugiyama Mutsumi 
Published: December 2023

Abstract
To achieve the field of photoelectrochemical water splitting, the modulating of the valence band maximum (VBM) grading on the surface of Cu(In, Ga)Se2 (CIGS) photoelectrodes via the deposition of additional In and Se (forming Cu-poor-CIGS layer) following CIGS growth was investigated. The resulting downshift of the Fermi level was likely to occur around the surface of the CIGS films for modulating the VBM grading, increasing the onset potential of the CIGS-related photoelectrodes. Moreover, a hole-blocking layer was obtained via modulated VBM grading of the CIGS-related photoelectrode, which increased the photocurrent density of the CIGS-related photoelectrode. Subsequently, a Cu-poor-CIGS/CIGS interface was formed for modulating the VBM grading using Cu-poor-CIGS, which contributed to increasing the photocurrent density owing to the enhancement of charge separation by the depletion layer in the Cu-poor-CIGS/CIGS interface. This study shows that water splitting can be effectively improved by modulating the VBM grading on the surface of CIGS-related photoelectrodes.

Abstract
In recent years, the excitation of surface phonon polaritons (SPhPs) in van der Waals materials received wide attention from the nanophotonics community. Alpha-phase Molybdenum trioxide (α-MoO3), a naturally occurring biaxial hyperbolic crystal, emerged as a promising polaritonic material due to its ability to support SPhPs for three orthogonal directions at different wavelength bands (range 10–20 μm). Here, we report on the fabrication, structural, morphological, and optical IR characterization of large-area (over 1 cm2 size) α-MoO3 polycrystalline film deposited on fused silica substrates by pulsed laser deposition. Due to the random grain distribution, the thin film does not display any optical anisotropy at normal incidence. However, the proposed fabrication method allows us to achieve a single α-phase, preserving the typical strong dispersion related to the phononic response of α-MoO3 flakes. Remarkable spectral properties of interest for IR photonics applications are reported. For instance, a polarization-tunable reflection peak at 1006 cm−1 with a dynamic range of ΔR = 0.3 and a resonance Q-factor as high as 53 is observed at 45° angle of incidence. Additionally, we report the fulfillment of an impedance matching condition with the SiO2 substrate leading to a polarization-independent almost perfect absorption condition (R < 0.01) at 972 cm−1 which is maintained for a broad angle of incidence. In this framework our findings appear extremely promising for the further development of mid-IR lithography-free, scalable films, for efficient and large-scale sensors, filters, thermal emitters, and label-free biochemical sensing devices operating in the free space, using far-field detection setups.

Published: December 2023

Abstract
Correct and reliable measurement data are crucial for state monitoring, safe operations, health assessment, and life prediction of integrated energy systems (IESs). Sensors are often installed in harsh environments and prone to all kinds of faults; therefore, it is necessary to diagnose sensor faults. A diagnostic method for sensor faults based on gradient histogram distribution (GHD) combined with light gradient boosting machine (LightGBM) is presented in this paper. This proposed method effectively utilizes the coupling information between the relevant parameters. The GHD efficiently extracted the time-domain characteristics of sensor faults and reduced the dimension of eigenvectors. This is beneficial to increasing the diagnostic speed. The kernel density estimation distributions of the gradient and eigenvectors for the sensor with strong correlation are similar, but that for the sensor with weak correlation are completely different. A LightGBM classifier trained based on the feature vectors was utilized to diagnose and classify the sensor faults. The diagnosis accuracy and the diagnosis time of this developed method were examined using the multiple-condition practical operation data of gas turbines in the IES. The experiment results demonstrate that the diagnostic accuracy of five sensor faults using this developed method is all above 90%. The diagnostic time is about 0.47–1.34 s, and is less than 2 s for the gradual faults.
A domain adaptation network with feature scale preservation for remaining useful life prediction of rolling bearings under variable operating conditions
Authors: She Daoming , Wang Hu , Zhang Hongfei , Chen Jin 
Published: December 2023

Abstract
Transfer learning and domain adaptation (DA) methods have been utilized in bearing prognostic and health management, but most of the current DA methods do not take into account the feature scale change of degraded features when aligning the feature distribution, and these methods are more suitable for the classification problem, which is more robust to the feature scale change. However, they perform poorly in regression problems. In addition, most of the remaining useful life (RUL) prediction methods require preprocessing such as statistical feature extraction on the signal, which makes the prediction process complicated. To solve the above problems, a DA method based on the representation subspace distance (RSD) is proposed for predicting the bearing RUL under different operating conditions. First, the proposed convolutional neural network (CNN) self-attention (SA) long short term memory network model is utilized to extract the deep features from the original signal, which overcomes the limitations of the CNN in extracting time series. Then, the RSD in the Riemannian geometry of the Grassmann manifold is proposed as a domain transfer loss to learn domain invariant features. The modified method can align the feature distribution of the source domain and the target domain without changing the feature scale. At the same time, the bases mismatch penalization is introduced to avoid destroying the semantic information of the features in the process of domain alignment. Finally, the effectiveness of the proposed method is verified by experiments on four types of transfer tasks, and its superiority is also demonstrated by comparison with other advanced methods.

Published: December 2023

Abstract
Subsea pipelines rely primarily on imaging sonar for detection and identification. We analyze the imaging principles of side scan sonar, multi-beam sonar, synthetic aperture sonar, seafloor penetrating sonar and forward-looking sonar. We discuss their effectiveness in detecting seabed pipelines, as well as their limitations in image recognition capabilities. As intelligent algorithms have become increasingly important in the field of image processing, we review the sonar image intelligent detection and recognition algorithms in the past six years and summarize the internal principles and application effects of classic algorithms such as Scale-Invariant Feature Transform, K-means algorithm, and constant false-alarm rate that currently show good application prospects. Simultaneously, we review the particular strengths exhibited by these algorithms, such as contour feature extraction, image segmentation and clustering, target recognition under background noise, etc. The research on intelligent processing of sonar images opens up a new way to solve the difficult problem of the seabed targets detection and recognition.

Analyzing the corrosion and tribocorrosion performances of monolayer TiO2 and bilayer TiO2-SiO2 coatings at different SBF temperatures
Authors: Acar M T 
Published: December 2023

Abstract
In this study, monolayer TiO2 coating was formed by the anodization method and bilayer TiO2-SiO2 coating was formed by the spin-coating method on commercially pure titanium (Cp-Ti) samples. The aim of this work compare the effects of monolayer and bilayer coatings at 37 °C and 60 °C in simulated body fluid (SBF) on the corrosion and tribocorrosion behaviors of Cp-Ti material. XRD and SEM were used for structural characterization of the coatings. Afterward, the adhesion strength of monolayer and bilayer coatings was investigated. The bilayer film began to separate from the Cp-Ti surface at higher forces, which was associated with energy dissipation between the layers, increased load-carrying capacity, and increased surface hardness. The best resistance was achieved from the bilayer film in tribocorrosion experiment at both 37 °C and 60 °C SBF temperatures; the result was attributed to higher surface hardness and film thickness. Consequently, untreated, monolayer, and bilayer Cp-Ti samples were tested for adhesion strength, corrosion, and tribocorrosion and bilayer samples exhibited the highest performance.

Published: December 2023

Abstract
The unique magnetic properties of triangulene and its homologues have generated a great deal of interest in recent years. Triangulene dimers, with their magnetic ground states and the detection of singlet-triplet spin excitations, have been synthesized on-surface by Mishra, and shown to be suitable for spintronics applications. In our study, we use first-principles calculations to investigate the photogalvanic effect (PGE) of triangulene dimers based nano-devices. The devices are constructed by two graphene nanoribbon electrodes and a triangulene dimer molecule connected by carbon chains, which has a spatial inversion symmetry. We find that when light irradiation is applied to the device, there are both spin-up and spin-down current induced with the same magnitude and opposite flowing directions. In this case, there is no accompanying charge current, but a finite pure spin current arises. Furthermore, we find that the currents generated by PGE can be tuned by impurity states. When nitrogen atoms are doped into the triangulene dimer molecule, we observe the emergence of impurity states, which supply other electron transition modes and result in a photo-current under different photon energy. Our findings provide a useful insight into the real application of tunable photoelectric carbon-based nano-devices. The PGE properties of triangulene dimers can be applied in the development of efficient spintronics devices.
Evaluation of indicators of railway-induced annoying vibration based on building measurements developed by TOD: a discussion

Published: December 2023

Abstract
The main negative impact of the residential buildings located on the cover structure of a Transit Oriented Development (TOD) metro depot is that residents would suffer from the train-induced annoying vibrations. Arguments accordingly arose on the possibility of evaluating indicators controversy for this application that acceleration data was more captured in the past while velocity would be more related to structure born noise. Therefore, this paper provided a relative comparison based on a measurement campaign that both velocity and acceleration sensors were installed together at the same time. The collected vibration accelerations and velocities are analyzed and discussed using the methods of transmission loss, coherence, and time and frequency domain analysis. The results indicated that even there was no difference for identifying the resonance frequency of structure, but the transit mobility and human annoyance evaluation were obviously different by using velocity or acceleration. Attempts to establish a relationship between the two indicators using the calculus method failed because they showed the largest error at the peak frequency at the same vibration level, which would have affected the evaluation results and the judgment on the choice of mitigation measures.
