Abstract
We infer the temporal changes in the pressure sources that induced crustal deformation during the 2018 Shinmoe-dake eruption using strain and tilt observations and discern that the deep magmatic activity associated with the early stage of this eruption began approximately 19 hours earlier than the previously defined onset of magmatic activity. Distinct tilt changes were observed from around 09:00 on 6 March to 12:00 on 8 March 2018 (JST), coincident with observed lava outflow into the crater and lava dome formation. Existing studies have attributed this tilt change to the onset of the deflation of a spherical pressure source located at ~ 7 km bsl (below sea level) to the northwest of Shinmoe-dake. Here we examine strain and tilt data that were acquired in the Kirishima volcanic group, and we find that the distinct changes in the measured strain at Isa-Yoshimatsu Observatory began at around 14:00 on 5 March. This change can be explained by the deflation of a spherical pressure source, thereby suggesting that the onset of magma ascent was earlier than previously thought. The time variation in the spherical pressure source is estimated using the time-dependent inversion of the Ensemble Kalman Filter; the deflation source ascended from ~ 11 to 7 km bsl during Phase 1 (14:00 on 5 March to 06:00 on 6 March) and descended from 7 to 8 km bsl during Phase 2 (06:00 on 6 March to 12:00 on 8 March). Interferometric synthetic aperture radar analysis suggests that a dike intrusion had occurred just below Shinmoe-dake crater until 5 March, and this inflatable crustal deformation is attributed to the emplacement of residual volcanic fluids from the 2011 eruption. It is also known that the surface eruptive activity increased during Phase 1, including an increase in ash venting from the night of 5 March. These strain and tilt observations therefore suggest that magma ascended from ~ 11 km bsl to the magma reservoir at 7 km bsl during Phase 1, followed by a deflation of the magma reservoir during Phase 2 due to the large magma supply to the surface.

Abstract
It is vital to develop a quick and reliable approach for nitrobenzene in gas phase detection. In this work, the quartz crystal microbalance (QCM) platform was used to take advantage of the porphyrin-based metal-organic frameworks (MOFs) of PCN-224 as a novel sensing material for the sensitive and selective detection of nitrobenzene vapor. Besides, a quick response time of only 16 s was achieved. Meanwhile, the frequency shift in gas sensor could be proportionally quenched in correlation with the concentration of nitrobenzene vapor. Additionally, this PCN-224-based sensor demonstrated great stability to nitrobenzene vapor. This foreshadowed the huge potential of nitrobenzene detection in gas phase for practical applications in public security.

Abstract
Objectives. The study aimed to analyze and quantify three-dimensional consecutive changes in facial swelling following impacted mandibular third molar (IM3M) surgery, and verify the repeatability and accuracy of three-dimensional(3D) photogrammetry.
Materials and methods. A total of 46 patients was scheduled to undergo IM3M surgery. 3D facial scanning images were obtained before surgery, and the first consecutive 5 days postoperatively. 3D software was used to assess and quantify volumetric changes between serial 3D images. Swelling of the face was measured in relation to the change in volume and thickness. Additionally, repeatability measurements for 3D images were performed on non-surgical side to gain access to the reliability and validity of this measurement.
Results. The maximum evident volumetric swelling was 23.64±11.15cm3, occurred on the second post-operative day, and the maximum thickness swelling was 6.08±2.25mm, occurred on the first post-operative day. The repeatability test showed no significant difference in pairs comparisons for the five non-surgical datasets.
Conclusions. Facial swelling after IM3M surgery reached its maximum volume on the 2nd postoperative day and its maximum thickness on the 1st postoperative day, and the 3D photogrammetry system is a reliable tool for measuring and monitoring changes in the swelling of the face.
Clinical Relevance. Quantity the consecutive changes over time in postoperative facial swelling following IMTM surgery，and verify the 3D photogrammetry is a reliable tool to monitor changes in facial swelling.
Ranking optimization investigation using hybrid AHP-TOPSIS MCDM technique on hybrid AA2024 ― Ceramic particulate alloy composite materials prepared through stir casting

Published: February 2023

Abstract
In reality, most often have to make decisions such as ranking the finite available materials alternatives that meet certain performance norms/criteria fulfilling certain objectives/goals. The problem becomes more complex as the number of criteria and alternatives increases. In such scenarios, Multi-Criteria-Decision-Making (MCDM) techniques such as hybrid AHP (Analytical hierarchy process) – TOPSIS (Technique for Order Preferences by Similarity to Ideal Solution) and others assist in quantitative decision making by accounting for qualitative human judgments. For example, materials often used in sliding wear applications have numerous criteria for their performance, such as physical, mechanical, thermal, thermo-mechanical, etc. that controls/monitor their realistic sliding wear performance. Consequently, material scholars find it challenging to subjectively rank the composite materials compositions. Alternatively, MCDM techniques aid in quick material selection/ranking decision making. This research work illustrates the application of a hybrid AHP- TOPSIS technique to the ranking of alloy composites. The properties defining data such as physical, mechanical, thermal, thermo-mechanical, etc. are weighted using AHP technique, thereafter, relative weights are used to rank the alloy composite compositions by TOPSIS method. The compositions comprise of AA2024 alloy as matrix phase and reinforcing phase consists of silicon carbide, silicon nitride and graphite particulates. The ranking analysis orders are found to be consistent with subjective analysis. Furthermore, the robust ranking order was validated by sensitivity analysis.

Abstract
Studying evaporation in the oceans is important for understanding the earth's climate and water cycle, and for making informed decisions about the management of natural resources. The research investigates the monthly changes in meteorological parameters and evaporation over the Arabian Sea in the year 2013. Several mathematical formulae have been used to study the same using meteorological data collected by multiple sensors of the buoy, and the results obtained through them were also compared with the satellite data. National Institute of Ocean Technology (NIOT) has been deploying OMNI buoys in the Indian Ocean to gather data on meteorological and subsurface conditions at depths of up to 500m. The average value of wind speed, sea surface temperature (SST), air temperature and relative humidity data were taken month wise from the AD06 buoy (180N, 670E) for the whole year (2013). Results comparison among the buoy data and satellite data reveals that the evaporation rate as given by the Dalton’s equation depends not only on the humidity gradient but also on the wind speed and the relative humidity. We have successfully demonstrated a strong correspondence between the buoy observations and the satellite estimates.

Abstract
Introduction:
Ventriculo-gallbladder shunt (VGS) has been recognized as a last-resort alternative to treat hydrocephalus when the peritoneum and/or other distal sites can no longer receive shunts. In some specific conditions, it may be conceded as a first-line treatment.
Case presentation:
We report the case of a 6- month-old girl with progressive post-hemorrhagic hydrocephalus and who presented a concomitant chronic abdominal symptom. Specific investigations ruled out acute infection and led to the diagnosis of chronic appendicitis. Both problems were managed in a one-stage salvage procedure consisting of laparotomy sanctioning to treat the abdominal pathology and seize the opportunity to perform a VGS as a first option since the abdomen is prone to ventriculoperitoneal shunt (VPS) failure.
Conclusion:
Only few cases have reported the use of VGS as the first option to handle uncommon complex cases due to abdominal or Cerebro-Spinal Fluid (CSF) conditions. We wish to draw attention to VGS as an effective procedure not only in children with multiple shunt failures but also as first-line management in some selected cases.
Long-term spectral wave climate in the Black Sea based on directional wave spectra
Authors: Amarouche Khalid , Akpınar Adem 
Published: February 2023

Abstract

Directional wave spectra describe complex sea states in frequency and directional domains and provide more detailed information than the bulk wave parameters. Spectral wave informations are important for the design of ships and offshore structures. Using hourly directional wave spectra hindcasted for a period of 42 years between 1979 and 2020, long-term spectral wave climate in the Black and Azov Seas was assessed. To determine the climatic wave spectrum, variance densities are averaged over the frequencies and directions for annual and seasonal, monthy scales. Futhermore, The individual wave system observed in each directional wave spectra are determined referring to the independent spectral peak at each observation. The different sea states conditions, including the uni-modal and multi-modal wave systems are classified and analysed; The energy, frequency, and direction of the three first prominent individual wave system peaks are deeply evaluated as a function of the sea state conditions. Occurrences as foction of spectral peak density and directions of the prominent individual wave system peaks are also computed and discussed. The results reveal that multi-modal spectra are more frequent in most regions, although the highest peak density values and lowest peak frequencies were observed within the wave spectra of uni-modal sea states. The spectral peak densities, frequencies, and directions depend both on the number of wave systems in the wave spectrum and on the geographic location. The first peaks in the wave spectra are mostly derived from two dominant directions and ~ 54% of the peaks had a density greater than 2 m2/Hz. In contrast, the second and third peaks in the wave spectra are typically derived from three or more dominant directions and rarely exceed a density of 2 m2/Hz.

Published: February 2023

Abstract

Hierarchical porous carbon aerogels were synthesized from liquefied wood via physical and chemical activation. The morphology and structure of the KOH treated carbon aerogel (K-LWCA) and steam treated carbon (H-LWCA) were systematically investigated by SEM, N2 adsorption, FTIR, XRD and XPS, and the electrochemical properties were evaluated based on cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy. The H-LWCA and K-LWCA had the high reached specific surface area (1996 and 1780 cm2 g− 1, respectively) and developed hierarchical porous structures. Compared with H-LWCA, K-LWCA showed the higher specific capacitance, better rate performance and superior cyclic stability due to more defects and hydrophilic functional groups. As expected, the K-LWCA exhibited the optimal mass-specific capacitance of 201.47 F g− 1 at 0.5 A g− 1, and achieved ideal capacitance retention of 70.15% at 20 A g− 1 as well as exceptional cycling stability of 94.11% retention after 5000 cycles. Moreover, the button symmetric supercapacitor device assembled based on K-LWCA demonstrated a specific capacitance of 117.78 F g− 1 at 0.5A g− 1 and presented an energy density of 9.2 Wh kg− 1 at a power density of 375W kg− 1. Accordingly, this work provides a novel approach for the preparation of biomass-derived carbon aerogel electrode materials in practical supercapacitor applications.

Abstract
Background
Patients with lymphoma and hepatitis B virus infection need to be treated with both chemotherapy and nucleotide analogues (NAs) therapy. However, the dynamic change of HBV DNA with the increase of chemotherapy cycles is lacking. It is unknown that whether HBV replication markers: quantitative hepatitis B core antibody (qAnti-HBc), HBV RNA, and hepatitis B virus core-related antigen (HBcrAg) are also sensitive to predict HBV reactivation (HBVr).
Methods
From 29th June 2010 to 6th December 2021, clinical data and serial serum samples were collected from patients with diffuse large B lymphoma and HBV infection. Serum HBV DNA load (real time fluorescent quantitative PCR), qAnti-HBc (developed chemiluminescent particle immunoassay), HBV RNA (simultaneous amplification testing method based on real-time fluorescence detection), and HBcrAg (Lumipulse G HBcrAg assay) were tested and actors related to HBV DNA reactivation were analyzed.
Results
Under the NAs, load of HBV DNA in 69 HBsAg + lymphoma patients declined from 3.15 (2.13–4.73) lg IU/ml at baseline to 1.00 (1.00-1.75) lg IU/ml at the end of chemotherapy, and further declined to 1.00 (1.00-1.04) lg IU/ml at the end of 24-month follow-up. Serum qAnti-HBc level decreased gradually during chemotherapy in HBsAg + lymphoma patients (F = 7.090, p = 0.009). Serum HBV RNA and HBcrAg levels stayed stabled. Multivariate analysis revealed that a higher level of qAnti-HBc (1.97 ± 1.20 vs. 1.12 ± 0.84 lg IU/ml, OR = 8.367, [95% CI:1.439–48.645], p = 0.018) and a higher level of HBV RNA (1.00 ± 1.13 vs. 0.37 ± 0.80 lg copies/ml, OR = 3.654, [95% CI:1.208–11.048], p = 0.022) were related to HBVr in HBsAg-/anti-HBc + lymphoma patients.
Conclusions
The HBV DNA load declined by NAs under chemotherapy in lymphoma patients. In HBsAg-/anti-HBc + lymphoma patients, higher level of baseline serum qAnti-HBc and HBV RNA predict the HBVr during chemotherapy.
Detection of orofacial pain of cardiac origin due to coronary artery disease: A case report and literature review
Authors: Choi Eunhye , Lee Yeon-Hee 
Published: February 2023

Abstract
Background. When diagnosing orofacial pain, clinicians should also consider non-odontogenic origin and systemic diseases as possible etiological factors, along with odontogenic origin. This case report aimed to provide information for early detection of orofacial pain of cardiac origin by dentists, when pain due to coronary artery disease is the only presenting symptom.
Case Presentation. A 60-year-old male patient with unexplained isolated bilateral jaw pain was referred to a dentist by an anesthesiologist whosuspected temporomandibular joint disorder. Oral examination and radiography of the temporomandibular joints revealed no bony abnormalities. Eventually, the patient was referred to a cardiologist for further evaluation since his pain was induced by physical activity. Coronary artery disease (CAD) was diagnosed using coronary computed tomographyangiography, and the pain was considered to be angina pectoris. Percutaneous coronary intervention was successfully done for the patient, after which his orofacial symptoms disappeared.
Conclusions. Isolated craniofacial pain of cardiac origin may lead to patients seeking dental care or visiting orofacial pain clinics. In these settings, dentists and orofacial pain specialists may contribute to the diagnosis of CAD and refer patients for cardiac evaluation and appropriate management.
Seismic Arrival-time Picking on Distributed Acoustic Sensing Data using Semi-supervised Learning
Authors: Zhu Weiqiang , Biondi Ettore , Li Jiaxuan , Yin Jiuxun , Ross Zachary , Zhan Zhongwen 
Published: February 2023

Abstract
Distributed Acoustic Sensing (DAS) is an emerging technology for earthquake monitoring and subsurface imaging. The recorded seismic signals by DAS have several distinct characteristics, such as unknown coupling effects, strong anthropogenic noise, and ultra-dense spatial sampling. These aspects differ from conventional seismic data recorded by seismic networks, making it challenging to utilize DAS at present for seismic monitoring. New data analysis algorithms are needed to extract useful information from DAS data, such as determining the first arrival times of P and S phases for earthquake monitoring and tomography. Previous studies on conventional seismic data demonstrated that deep learning models could achieve performance close to human analysts in picking seismic phases after training on large datasets of manual labels. However, phase picking on DAS data is still a difficult problem due to the lack of manual labels. Further, the differences in mathematical structure between these two data formats, i.e., ultra-dense DAS arrays and sparse seismic networks, make model fine-tuning or transfer learning difficult to implement on DAS data. In this work, we design a new approach using semi-supervised learning to solve the phase-picking task on DAS arrays. We use a pre-trained PhaseNet model as a teacher network to generate noisy labels of P and S arrivals on DAS data and apply the Gaussian mixture model phase association (GaMMA) method to refine these noisy labels to build training datasets. We develop a new deep learning model, PhaseNet-DAS, to process the 2D spatial-temporal data of DAS arrays and train the model using DAS arrays at Long Valley and Ridgecrest, California. The new deep learning model achieves high picking accuracy and good earthquake detection performance. We then apply the model to process continuous data and build earthquake catalogs directly from DAS recording. Our approach using semi-supervised learning provides a way to build effective deep learning models for DAS, which have the potential to improve earthquake monitoring using large-scale fiber networks.

Bird species richness and diversity responses to land use change in the Lake Victoria Basin, Kenya
Authors: Mugatha S. , Ogutu Joseph O. , Piepho Hans-Peter , Maitima Joseph M. 
Published: February 2023

Abstract

The increasing demand for cultivated lands driven by human population growth, escalating consumption and activities, combined with the vast area of uncultivated land, highlights the pressing need to better understand the biodiversity conservation implications of land use change in Sub-Saharan Africa. Land use change alters natural wildlife habitats with fundamental consequences for biodiversity. Consequently, species richness and diversity typically decline as land use changes from natural to disturbed. We assess how richness and diversity of avian species, grouped into feeding guilds, responded to land use changes, primarily expansion of settlements and cultivation at three sites in western Kenya, following tsetse control interventions. Each site consisted of a matched pair of spatially adjacent natural/semi-natural and settled/cultivated landscapes. Radical changes occurred in bird species richness and diversity in the disturbed relative to the natural landscape. Whilst species diversity was far lower, a couple of finch species were more common in the disturbed landscapes. Specifically, estrildid finches were often observed on the scrubby edges of modified habitats. In contrast, the natural and less disturbed wooded areas had relatively fewer estrildid species and were completely devoid of several other species. In aggregate, land use changes significantly reduced bird species richness and diversity on the disturbed landscapes. Accordingly, land use planning should integrate conservation principles that preserve salient habitat qualities required by different bird species, such as adequate patch size and habitat connectivity, conserve viable bird populations and restore degraded habitats to alleviate adverse impacts of land use change on avian species richness and diversity.
