Published: March 2023

Background: Early studies found that the mental health problems rate was relatively high in university students. We aimed to investigate the prevalence of mental problems and associated factors in university students. Methods: We conducted a cross-sectional descriptive study at Supara mental health service in the Faculty of Medicine Vajira Hospital between February 2020 to June 2021. The primary outcome was the prevalence of psychiatric diagnosis according to the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10). The secondary assessments included the Patient Health Questionnaire-9 (PHQ-9), 8 items from the Mini International Neuropsychiatric Interview (MINI) to assess suicidal risk (8Q), and the Thai Mental Health Indicator (TMHI-15). The prevalence of mental health problems was presented by frequency and percentage. In addition, multivariable regression analysis was used to identify potential predictors of mental health problems. Results: A total of 184 participants (62% female; mean age = 22.49 years (SD 3.93) were recruited. The depressive disorders, adjustment disorders, and anxiety disorders rates were 57.1%, 15.2% and 13.6%, respectively. Grade point averages (GPAs) below 3.0 (OR=3.09, 95%CI: 1.17-8.14) and a family history of mental disorder (OR=3.40, 95%CI: 1.10-10.48) were significant associated factors of moderate to severe mental health problems. Detecting and screening these factors may help the university to provide early detection and treatment for students. Conclusions: Depressive disorders were the most common mental health disorders. Females, low GPAs and a family history of mental disorder were predictors of moderate to severe mental health problems.
Success rate of repeated cycles of induction in labour in a UK clinical setting: A cohort study
Authors: Alojayli Anas , Haloob Rahim 
Published: March 2023

Background: Births are increasingly started artificially using medications such as prostaglandin, oxytocin, or other mechanical methods, a process known as induction of labour (IOL). The aim of the study was to identify the success rate of a repeat cycle of induction of labour (IOL) with prostaglandins, and any association between smoking and patient response to prostaglandin. Methods: This was a retrospective cohort study set in Basildon and Thurrock University Hospital, UK. IOL data from patients were collected between 1 January 2021 and 30 March 2021. Data were retrieved from hospital records and categorised by prostaglandin cycle(s), administration of oxytocin, artificial rupture of membranes (ARM), spontaneous rupture of membranes (SROM), smoking status, patient BMI, age, ethnicity, gestation age, Bishop score, and delivery method (assisted, unassisted, or Caesarean (C-)section). The data were analysed using Chi-square, binomial and multinomial logistic regression. The success rate was interpreted from relative frequencies of delivery method (unassisted, assisted or C-section). Results: Unassisted vaginal delivery (n =121; 48.0%) was the most common outcome with prostaglandin IOL followed by C-section (n = 105 41.7%). Only 10.3% had an assisted vaginal delivery. Of those who had a repeated IOL cycle, 85.7% had a C-section. There was no difference in prostaglandin administration by smoking status or any association between smoking status and mode of delivery in IOL. Conclusions: Repeat cycle of IOL does not enhance the vaginal delivery with only 14.3% unassisted vaginal births. There was no evidence that smoking impacted on response to prostaglandins or method of delivery.

Published: March 2023

This paper reports the method of generating a 355 nm ultraviolet (UV) quasicontinuous pulse laser by using two periodically poled Mg-doped lithium niobate (PPMgLN) crystals in a single-pass cascade. In the first PPMgLN crystal with a length of 20 mm and a first-order-poled period of 6.97 µm, the second-harmonic light of a 532 nm laser with 780 mW is generated from the 1064 nm laser with an average power of 2 W; After that, in the second PPMgLN crystal with a length of 15 mm and a third-order-poled period of 5.30 µm, the 532 nm laser generated was combined with the 1064 nm laser remaining through the first PPMgLN crystal to obtain a 355 nm UV laser with a maximum output average power of 20 mW, a repetition rate of 40 kHz, a pulse width of 49 ns, and a peak power of 10 W. Compared with existing reports, we have higher peak power and single pulse energy, which is an important application of the PPMgLN crystal. This paper will provide an important case for the realization of a 355 nm UV quasicontinuous or a continuous laser.
High-efficiency dual-layer grating coupler for vertical fiber-chip coupling in two polarizations
Authors: Li Ke , Zhu Jingping , Duan Qihang , Hou Xun 
Published: March 2023

Efficient coupling between optical fibers and high-index-contrast silicon waveguides is essential for the development of integrated nanophotonics. Herein, a high-efficiency dual-layer grating coupler is demonstrated for vertical polarization-diversity fiber-chip coupling. The two waveguide layers are orthogonally distributed and designed for y- and x-polarized LP01 fiber modes, respectively. Each layer consists of two 1D stacked gratings, allowing for both perfectly vertical coupling and high coupling directionality. The gratings are optimized using the particle swarm algorithm with a preset varying trend of parameters to thin out the optimization variables. The interlayer thickness is determined to ensure efficient coupling of both polarizations. The optimized results exhibit record highs of 92% (−0.38dB) and 85% (−0.72dB) 3D finite-difference time-domain simulation efficiencies for y and x polarizations, respectively. The polarization-dependent loss (PDL) is below 2 dB in a 160 nm spectral bandwidth with cross talk between the two polarizations less than −24dB. Fabrication imperfections are also investigated. Dimensional offsets of ±10nm in etching width and ±8 nm in lateral shift are tolerated for a 1 dB loss penalty. The proposed structure offers an ultimate solution for polarization diversity coupling schemes in silicon photonics with high directionality, low PDL, and a possibility to vertically couple.

BackgroundCOVID-19 has affected Healthcare workers in many ways. One of the important areas is the psychological impact. This study aims to examine the effects of the COVID-19 outbreak on the mental health of Healthcare Professionals (HCP) and associated factors.MethodsA cross-sectional study was conducted among healthcare providers in the Emirates of Abu Dhabi, United Arab Emirates, between April 11th, and July 23rd, 2020. The study was conducted by using an online anonymous Self-administered questionnaire through the survey monkey platform. A convenient sampling method was used to distribute the online survey link through the organization’s email network admin list and smartphone messaging. Descriptive statistics, t-tests, and multivariant linear regression were used.ResultsAnxiety and depression risk scores were measured in a total of 1268 participants of healthcare providers. More than half of the participants reported symptoms of anxiety (51.5%). Depression symptoms were revealed in 38.3% of participating providers. A mild risk of anxiety was reported in 28.8% of the participants and 12.68% of the participants registered moderate anxiety risk scores and 9.95% reported a severe risk of anxiety. Among all participants, 4.3% and 2.7% reported moderately severe and severe risk of depression, respectively, while 22.5% and 8.8% of the participating healthcare providers documented mild and moderate depression risk. Anxiety and depression risk scores were significantly and negatively associated with age and working in primary health care.ConclusionsThe high prevalence of anxiety and depression recorded among HCP during the pandemic suggests that mental health intervention and support are necessary to ensure the psychological well-being of HCP.

Objectives
Fibrotic interstitial lung disease (ILD) includes a large group of conditions that lead to scarring of the lungs. The lack of available 5-level EuroQol 5D (EQ5D) data has limited the ability to conduct economic evaluations in ILD. The purpose of this study was to develop and validate a mapping algorithm that predicts EQ5D utilities from commonly collected pulmonary function measurements (forced vital capacity [FVC] and diffusing capacity of the lung for carbon monoxide [DLCO]) in fibrotic ILDs.

Methods
EQ5D utility and pulmonary function measurements from the Canadian Registry for Pulmonary Fibrosis were included. Ordinary least squares (OLS), beta regression, two-part, and tobit models were used to map EQ5D utilities from FVC or DLCO. Model performance was assessed by comparing the predicted and observed utilities. Subgroup analyses were also conducted to test how well models performed across different patient characteristics. The models were then externally validated in the Australian Idiopathic Pulmonary Fibrosis Registry.

Results
The OLS model performed as well as other more complex models (root mean squared error: 0.17 for FVC and 0.16 for DLCO). As with the other models, the OLS algorithm performed well across the different subgroups (except for EQ5D utilities < 0.5) and in the external validation cohort.

Conclusion
We developed a mapping algorithm that predicts EQ5D utilities from FVC and DLCO, with the intent that this algorithm can be applied to clinical trial populations and real-world cohorts that have not prioritized collection of health-related utilities. The mapping algorithm can be used in future economic evaluations of potential ILD therapies.
White matter hyperintensities in cholinergic pathways may predict poorer responsiveness to acetylcholinesterase inhibitor treatment for Alzheimer’s disease
Authors: Lee Li-Hua , Wu Shu-Ching , Ho Cheng-Feng , Liang Wan-Lin , Liu Yi-Chien , Chou Chia-Ju 
Published: March 2023

Background
Acetylcholinesterase inhibitor (AChEI) drug regimens are the mainstay treatment options for patients with Alzheimer’s disease (AD). Herein, We examined the association between clinical response to AChEI and white matter hyperintensities on magnetic resonance imaging (MRI) scan at baseline.

Methods
Between 2020 and 2021, we recruited 101 individuals with a clinical diagnosis of probable AD. Each participant underwent complete neuropsychological testing and 3T (Telsa) brain magnetic resonance imaging. Responsiveness to AChEI, as assessed after 12 months, was designated as less than two points of regression in Mini-Mental State Examination scores (MMSE) and stable clinical dementia rating scale. We also evaluated MRI images by examining scores on the Cholinergic Pathways Hyperintensities Scale (CHIPS), Fazekas scale, and medial temporal atrophy (MTA) scale.

Results
In our cohort, 52 patients (51.4%) were classified as responders. We observed significantly higher CHIPS scores in the nonresponder group (21.1 ± 12.9 vs. 14.9 ± 9.2, P = 0.007). Age at baseline, education level, sex, Clinical Dementia Rating sum of boxes scores, and three neuroimaging parameters were tested in regression models. Only CHIPS scores predicted clinical response to AChEI treatment.

Conclusion
WMHs in the cholinergic pathways, not diffuse white matter lesions or hippocampal atrophy, correlated with poorer responsiveness to AChEI treatment. Therefore, further investigation into the role of the cholinergic pathway in AD is warranted.

Abstract
Single-molecule localization microscopies have gained much attention for their efficient realization of a sub-diffraction-limit imaging with the resolution down to the 10-nm range. In contrast to conventional localization microscopes, which rely on particular fluorescent probes in specific conditions, metamaterial-assisted super-resolution microscopies can be implemented with any fluorescent dye under general conditions. Here, we present a systematic study of fluorescence engineering in metamaterial assisted localization microscopy by using cyclic group metasurfaces coated with a fluorescent film. Tailored variations are clearly demonstrated in both the photoluminescence intensity and the photobleaching lifetime of fluorophores based on the spatially varied Purcell effect near the metasurfaces. The enhanced emissions and blinking dynamics of the fluorophores on these metasurfaces lead to an increased signal-to-noise ratio, and therefore give rise to a super-resolution localization image with 0.9-nm localization accuracy. Our results are not only beneficial for super-resolution localization imaging but also push the control of light–matter interactions beyond the diffraction limit.
Numerical analysis of vibration response of elastic tube bundle of heat exchanger based on fluid structure coupling analysis
Authors: Su Wei , Tao Kerui , Liu Fansheng 
Published: March 2023

Abstract
A tube bundle heat exchanger is a typical heat exchange equipment that exchanges heat between two fluids with different temperatures. Through this equipment, one fluid can be cooled down and another fluid can be heated up to meet their respective needs. The equipment is widely used in chemical, petroleum, pharmaceutical, energy, and other industrial sectors, and is one of the indispensable and important equipments in chemical production. To improve the heat transfer performance and service life of the heat exchanger, a numerical analysis of the vibration response of the elastic tube bundle in the heat exchanger based on fluid–structure coupling analysis is proposed. Using the weak coupling method of fluid–structure coupling, the vibration response of multiple rows of elastic tube bundles induced by shell side fluid in a heat exchanger with different tube row spacing and different tube row numbers is studied numerically, and the effects of shell side fluid and tube side fluid on the vibration response of elastic tube bundles are compared and analyzed. The results show that the maximum relative error of monitoring point amplitude is 43.36% when H = 40 mm and 10.17% when H = 70 mm. For connection IV, the maximum relative error of monitoring point amplitude is 31.71% when H = 40 mm and 24.08% when H = 70 mm. This is because when H is small, the interaction between rows of tube bundles is strong, so the amplitude changes violently with the number of the tube bundle. The step-by-step calculation strategy of rough calculation and actuarial calculation proposed in this article can greatly reduce the calculation time and improve the calculation efficiency.
Hydrovolcanic Explosions at the Lava Ocean Entry of the 2018 Kilauea Eruption Recorded by Ocean-Bottom Seismometers
Authors: Banerjee Puja , Shen Yang 
Published: March 2023

AbstractFrom the beginning of May 2018, the Kilauea Volcano on the island of Hawaii experienced its largest eruption in 200 yr followed by a period of unrest for months. Because hot molten lava entered the ocean from the ocean-entry point near the lower East Rift Zone, the lava–water interaction led to explosions. Some explosions were near the water surface and ejected fragments of lava, also known as lava bombs. In the early morning on 16 July 2018, one of those lava bombs, which was almost the size of a basketball, hit a sightseeing boat and injured 23 people. In this study, we analyzed the hydrophone data recorded from July to mid-September by ocean-bottom seismometers (OBSs) deployed offshore near the ocean entry point to identify and locate the hydroacoustic signals of the lava–water explosions. Acoustic signals of hydrovolcanic explosions are characterized by a short duration (less than a few seconds) and a broad frequency range (at least up to 100 Hz). To automate event detection, a short-term average versus long-term average method was applied to the complete dataset. Approximately 4300 events were detected and located near the coastline and further used to prepare a catalog. The distribution of the lava–water explosions is consistent with the pattern of the offshore lava delta formed during the 2018 eruption. Identifying such hydroacoustic signals recorded by OBSs may provide new avenues of research using various seismoacoustic events associated with volcanic eruptions.

Published: March 2023

Aim. The article is to identify effective conditions for the development of ecological culture in Dagestan schools in the interests of sustainable regional development.Material and Methods. To achieve this goal, adequate methods were used, taking into account the specifics of each stage of the work: analysis of scientific literature (psychological-pedagogical, methodological and environmental), regulatory and programme-methodical documents about the problem; observation, pedagogical experiment, testing, study of pedagogical experience and methods of mathematical processing of experimental results (%2-criterion).Results. The development of the global environmental crisis has set before society the task of survival and ensuring the existence of mankind, in the context of the concept of "sustainable development of mankind", considered as development that meets the needs of the present and does not jeopardize the ability of future generations to meet their needs. This allows us to state the relevance of introducing effective models of environmental education for sustainable development (one-subject, multisubject and mixed) into school curricula. The results of the study show the effectiveness of various types of ecologisation (subject, inter-subject and meta-subject) and the "mixed model". A textbook on regional ecology (Ecology of Dagestan) was developed, taking into account the specifics of the laws of functioning of the ecosystems of the planet and the region. With the inclusion of regional ecology in the "mixed model", school environmental education for sustainable development has been completed.Conclusions. Environmental education in the interests of sustainable development and preservation of the natural and cultural heritage of the region is effective in the greening of school disciplines and the use of a "mixed model", and the inclusion of a national and regional component in their content.
