Published: December 2023

Abstract
On 1st October 2022, a moderate crustal earthquake with Mw 5.8 occurred in the northen part of Tarutung region and was strongly felt by the local peoples and followed by massive damages. The occurrence of the Tarutung earthquake was firstly assumed in the southern part of the Renun fault then updated to the pull-apart system of Toru fault. Here, we concern about the ground paramaters that generated a massive shaking and connect with the recent geologic units beneath the Tarutung region. The peak ground acceleration (PGA) and peak ground velocity (PGV) clearly show an amplification case may arise in the basin formation that consists of Alluvium Formation whereas the attenuation to the west and east part with Martimbang and Sipoholon Caldera Formation. The PGV was ranging at 0 – 10 cm/s and the PGA was ranging at 0% – 16% gal which are suitable with the intensity range at 3 – 6 MMI. The PGV, PGA and intensity relationship show a possibility of the building damage percentage is up to 80% and 50% of the surrounding area may potentially experience a complete damage. The pseudo-spectral acceleration (PSV) at 0.3s, 1.0s, and 3.0s also show a potential damage that can be found at low-moderate building structure with 8% - 16% gal. The ground parameters show an empirical relationship that can be used to assess the possible of geologic units in the Tarutung region. Furthermore, our result benefits can be applied to support the mitigation program and environmental planning in Tarutung region in the near future.

Published: December 2023

Abstract
Monel® alloy 400 has excellent corrosion resistance and finds applications in marine industries. The processing of marine components requires high processing efficiency and a quality finish. Hence, this research aims to investigate the effects of the laser processing parameters such as laser fluence, scanning velocity, hatching distance, and the scanning pass on the ablation rates and efficiency, chemistry, and nanomechanical properties of the Monel® alloy 400 after pulsed picosecond (ps) laser ablation. From the experimental findings, the ablation depth increases as the laser fluence increases while decreasing as the scanning velocity increases. Surface roughness was noted to increase as the laser fluence increased. The findings demonstrated that the ablation rate increases as laser fluence increases while ablation efficiency decreases. Energy dispersive x-ray spectroscopy (EDX) showed that the elemental composition of laser-ablated zones is almost similar to that of the polished sample. X-ray spectroscopy (XPS) shows that the outer layer on the surface of Monel® alloy 400 is composed of NiO and CuO. The hardness and Young’s modulus of the laser-processed alloy were found to be less than those of the bulk material. This study can be used to establish optimal processing parameters for the ultrafast ps laser processing of materials to achieve high ablation efficiency with a high-quality surface finish for industrial applications.

Published: December 2023

Abstract
We successfully synthesised nickel vanadate (NiVO3) nanocomposite by an inexpensive hydrothermal technique. Several analytical methods have been employed to characterise the synthesised nanocomposite. The crystal structure of NiVO3 is orthorhombic, and its crystallite size is around 10.3 nm. The NiVO3 nanocomposite has an optical band gap of 2.62 eV from the absorption spectra analysis. At a current density of 5 Ag−1, the NiVO3 nanocomposite exhibits a specific capacitance value of 398 Fg−1 and a retention rate of almost 90% after 2000 cycles. Furthermore, stability studies show that at a current density of 5 Ag−1, 90% of the capacitance is retained for 4000 cycles. The photocatalytic studies to break down the industrial pollutant Fast Orange Red (F-OR) dye show a 98.7% decolourization rate after 120 min of exposure to UV light irradiation. These features promote the creation of such nanocomposites for practical energy and environmental applications while providing a deeper understanding of the material’s characteristics.
Effect of a negative DC bias on a capacitively coupled Ar plasma operated at different radiofrequency voltages and gas pressures

Published: December 2023

Abstract
The effect of a negative DC bias, |V
dc|, on the electrical parameters and discharge mode is investigated experimentally in a radiofrequency (RF) capacitively coupled Ar plasma operated at different RF voltage amplitudes and gas pressures. The electron density is measured using a hairpin probe and the spatio-temporal distribution of the electron-impact excitation rate is determined by phase-resolved optical emission spectroscopy. The electrical parameters are obtained based on the waveforms of the electrode voltage and plasma current measured by a voltage probe and a current probe. It was found that at a low |V
dc|, i.e. in α-mode, the electron density and RF current decline with increasing |V
dc|; meanwhile, the plasma impedance becomes more capacitive due to a widened sheath. Therefore, RF power deposition is suppressed. When |V
dc| exceeds a certain value, the plasma changes to α–γ hybrid mode (or the discharge becomes dominated by the γ-mode), manifesting a drastically growing electron density and a moderately increasing RF current. Meanwhile, the plasma impedance becomes more resistive, so RF power deposition is enhanced with |V
dc|. We also found that the electrical parameters show similar dependence on |V
dc| at different RF voltages, and α–γ mode transition occurs at a lower |V
dc| at a higher RF voltage. By increasing the pressure, plasma impedance becomes more resistive, so RF power deposition and electron density are enhanced. In particular, the α–γ mode transition tends to occur at a lower |V
dc| with increase in pressure.

Published: December 2023

Abstract
Fluid lubricated bearings have been widely adopted as support components for high-end equipment in metrology, semiconductor devices, aviation, strategic defense, ultraprecision manufacturing, medical treatment, and power generation. In all these applications, the equipment must deliver extreme working performances such as ultraprecise movement, ultrahigh rotation speed, ultraheavy bearing loads, ultrahigh environmental temperatures, strong radiation resistance, and high vacuum operation, which have challenged the design and optimization of reliable fluid lubricated bearings. Breakthrough of any related bottlenecks will promote the development course of high-end equipment. To promote the advancement of high-end equipment, this paper reviews the design and optimization of fluid lubricated bearings operated at typical extreme working performances, targeting the realization of extreme working performances, current challenges and solutions, underlying deficiencies, and promising developmental directions. This paper can guide the selection of suitable fluid lubricated bearings and optimize their structures to meet their required working performances.

Transcriptional survey of abiotic stress response in maize (Zea mays) in the level of gene co-expression network and differential gene correlation analysis
Authors: Nazari Leyla , Zinati Zahra 
Published: December 2023

AbstractAbstract. Maize may be exposed to several abiotic stresses in the field. Therefore, identifying the tolerance mechanisms of natural field stress is mandatory. Gene expression data of maize upon abiotic stress were collected, and 560 differentially expressed genes (DEGs) were identified through meta-analysis. The most significant gene ontology terms in up-regulated genes were ‘response to abiotic stress’ and ‘chitinase activity’. ‘Phosphorelay signal transduction system’ was the most significant enriched biological process in down-regulated DEGs. The co-expression analysis unveiled seven modules of DEGs, with a notable positive correlation between the modules and abiotic stress. Furthermore, the statistical significance was strikingly high for the turquoise, green and yellow modules. The turquoise group played a central role in orchestrating crucial adaptations in metabolic and stress response pathways in maize when exposed to abiotic stress. Within three up-regulated modules, Zm.7361.1.A1_at, Zm.10386.1.A1_a_at and Zm.10151.1.A1_at emerged as hub genes. These genes might introduce novel candidates implicated in stress tolerance mechanisms, warranting further comprehensive investigation and research. In parallel, the R package glmnet was applied to fit a logistic LASSO regression model on the DEGs profile to select candidate genes associated with abiotic responses in maize. The identified hub genes and LASSO regression genes were validated on an independent microarray dataset. Additionally, Differential Gene Correlation Analysis (DGCA) was performed on LASSO and hub genes to investigate the gene-gene regulatory relationship. The P value of DGCA of 16 pairwise gene comparisons was lower than 0.01, indicating a gene–gene significant change in correlation between control and abiotic stress. Integrated weighted gene correlation network analysis and logistic LASSO analysis revealed Zm.11185.1.S1_at, Zm.2331.1.S1_x_at and Zm.17003.1.S1_at. Notably, these 3 genes were identified in the 16 gene-pair comparisons. This finding highlights the notable significance of these genes in the abiotic stress response. Additional research into maize stress tolerance may focus on these three genes.
On selection and conditioning in multiple testing and selective inference
Authors: Goeman Jelle J , Solari Aldo 
Published: December 2023

Summary
We investigate a class of methods for selective inference that condition on a selection event. Such methods follow a two-stage process. First, a data-driven collection of hypotheses is chosen from some large universe of hypotheses. Subsequently, inference takes place within this data-driven collection, conditioned on the information that was used for the selection. Examples of such methods include basic data splitting as well as modern data-carving methods and post-selection inference methods for lasso coefficients based on the polyhedral lemma. In this article, we take a holistic view of such methods, considering the selection, conditioning and final error control steps together as a single method. From this perspective, we demonstrate that multiple testing methods defined directly on the full universe of hypotheses are always at least as powerful as selective inference methods based on selection and conditioning. This result holds true even when the universe is potentially infinite and only implicitly defined, such as in the case of data splitting. We provide general theory and intuition before investigating in detail several case studies where a shift to a nonselective or unconditional perspective can yield a power gain.
Social Value of Public Information in Bargaining
Authors: Basak Deepal 
Published: December 2023

Abstract
We consider a bargaining game in which both sides are uncertain about their opponent’s commitment, which leads to delay and welfare loss in equilibrium. We address the following question: does ex ante better public information about a player improve expected social welfare? We show that if the information cannot turn the bargaining table (turns the weak bargainer into a strong one and vice versa), more information does not help. More information about a weak bargainer has zero impact, whereas that about the strong bargainer is strictly detrimental. Moreover, by specialising in a binary signal structure, we show that if the information is more accurate in every state, it improves social welfare when it can turn the table.
Cervical headgear effectiveness in distalizing molars in relation to patient compliance
Authors: Gratsia Sofia , Cocos Alina , Vastardis Heleni , Halazonetis Demetrios 
Published: December 2023

Summary

Objectives
The purpose of this study was to measure the effectiveness of the cervical headgear for distalizing first permanent maxillary molars in relation to hours of use.

Methods
This was a one-centre, prospective, clinical study conducted at the Department of Orthodontics, School of Dentistry, National and Kapodistrian University of Athens, Athens, Greece. Participants (N = 26; 17 females, 9 males) were patients with no history of orthodontic treatment, no syndromes or clefts, and Angle’s Class II malocclusion, where the treatment plan included a cervical headgear. They were instructed to wear the appliance for at least 12 h per day. A TheraMon® microsensor was embedded in the headgear’s strap to objectively measure wear-time. To measure tooth movement, pre- and post-treatment digital models were superimposed, using the palate as a reference area; translation and rotation were measured along three axes. Superimposition and movement measurements were made with the Viewbox 4 software.

Results
Average treatment time and headgear wear were 130 days and 55 days, respectively, i.e. 10.1 h/day. During this period, distal movement averaged 1.75 mm with high variability (min 0.2 mm, max 4.5 mm). Distal tipping and rotation had an average of approximately 5 °C. Cumulative headgear wear was significantly correlated with distal movement (r2 = 0.32, P &lt; .002), distal tipping (r2 = 0.27, P &lt; .01), and distal rotation around the long axis of the tooth (r2 = 0.20, P &lt; .05).

Conclusion
Compliance is critical for having a successful clinical outcome. Distalization of the molar with a cervical headgear is correlated with the cumulative hours of appliance use, with hours per day being a weaker predictor.
Biomechanical analysis of miniscrew-assisted molar distalization with clear aligners: a three-dimensional finite element study
Authors: Guo Runzhi , Lam Xiang Yao , Zhang Liwen , Li Weiran , Lin Yifan 
Published: December 2023

Abstract

Background/Objectives
To compare the biomechanical characteristics of maxillary molar distalization with clear aligners in conjunction with three types of miniscrew anchorage.

Materials/Methods
Three-dimensional (3D) finite element models of maxillary molar distalization with clear aligners and three types of miniscrew anchorage were established, including (A) control group, (B) direct buccal miniscrew anchorage group, (C) direct palatal miniscrew anchorage group, and (D) indirect buccal miniscrew anchorage group. The 3D displacement of maxillary teeth and the principal stress (maximum tensile and compressive stress) on the root and periodontal ligament (PDL) during molar distalization were recorded.

Results
The tooth displacement pattern during maxillary molar distalization in the four groups showed similarities, including labial tipping of anterior teeth, mesial and buccal tipping of premolars, and distal and buccal tipping of molars, but with varying magnitudes. Group C exhibited the greatest molar distalization, with the first molar achieving 0.1334 mm of crown distalization. Group D demonstrated a notable buccal crown movement (0.0682 mm) and intrusion (0.0316 mm) of the first premolar. Compared to Groups A and B, Groups C and D showed less labial crown tipping of the central incisor. Group B showed the greatest amount of maxillary incisor intrusion (central incisor: 0.0145 mm, lateral incisor: 0.0094 mm). Moreover, Groups C and D displayed significantly lower levels of compressive and tensile stress in the roots and PDL of the maxillary central and lateral incisors.

Limitation
Molar distalization is a dynamic process involving sequential tooth movement stages; however, our research primarily examined the tooth movement patterns in the initial aligner.

Conclusions/Implications
The use of miniscrew anchorage, especially direct palatal miniscrew anchorage, may enhance the treatment efficacy of maxillary molar distalization with clear aligners, leading to increased molar distalization, reduced mesial movement of premolars, and minimized labial tipping of anterior teeth.

Published: December 2023

Abstract

Background
Coronavirus disease 2019 (COVID-19) caused major disruptions in healthcare services worldwide. Yet, little is known about the association between perceived disruption in healthcare services and socio-demographic factors, pre-existing health conditions as well as concurrent physical and psychological symptoms.

Methods
Leveraging data from the Icelandic COVID-19 National Resilience Cohort, we performed a repeated measure analysis among 15 754 participants who responded to the question on perceived disruption in healthcare services from December 2020 to July 2021, to explore its association with socio-demographic factors, health indicators and conditions. Furthermore, we performed a longitudinal analysis among 7848 participants with two repeated measures to explore the association between timing and duration of perceived disruption in healthcare services and changes in depression, anxiety, sleep quality and somatic symptoms.

Results
The prevalence of perceived disruption in healthcare services slightly decreased over time (P &lt; 0.01). Perceived disruption in healthcare services was more prevalent among individuals with pre-existing health conditions, i.e. history of psychiatric disorders (prevalence ratio = 1.59, 95% confidence interval 1.48–1.72) and chronic somatic conditions [1.40 (1.30–1.52)]. However, no increase in the prevalence of perceived disruption in healthcare services was observed among individuals diagnosed with COVID-19 [0.99 (0.84–1.18)]. Moreover, we found that emerging perceived disruption in healthcare services was associated with an increase in symptoms of mental illness during the pandemic (βs 0.06–0.68).

Conclusions
A disruption in healthcare services during the COVID-19 pandemic was reported by vulnerable groups, while the Icelandic healthcare system managed to maintain accessible services to individuals with COVID-19.
Telomere Length Is a Driving Hallmark for Aging-Related Biochemical Hallmarks: Evidence From the Shared Genetic Effect and Causal Inference

Published: December 2023

Abstract
Telomere shortening is an important sign and driving factor of aging, but its association mechanisms and causal effects with other aging-related biochemical hallmarks are largely unknown. This study first performed comprehensive genetic analyses (eg, shared genetic analysis, pleiotropic analysis, and gene enrichment analysis) to detect the underlying molecular mechanisms for the associations between telomere length (TL) and aging-related biochemical hallmarks. Then, further bidirectional Mendelian randomization (MR) analyses investigated the causal effects between TL and other biochemical hallmarks. The genetic correlations were negative between TL and growth differentiation factor-15 (GDF15) (p = .024), C-reactive protein (p = .007), hemoglobin A1c (p = .007), and red blood cell (RBC) (p = .022), but positive between TL and insulin-like growth factor 1 (IGF-1) (p = .002) and white blood cell counts (p = .007). The increased TL has causal effects on the low levels of GDF15 (p = 3.73E-06), sex hormone binding globulin (p = 6.30E-06), testosterone (p = 5.56E-07), fasting insulin (p = 2.67E-05), and RBC (p = 1.54E-05), but the higher levels of IGF-1 (p = 3.24E-07). In conclusion, the observed phenotypic correlations between TL and aging-related biochemical hallmarks may arise from a combination of shared genetic components and causal effects. Telomere length is regarded as a driving hallmark for aging-related biochemical hallmarks.
