Published: November 2023

Abstract

Background
Among all urogenital fistulas Vesicouterine fistula (VUF) is the rarest. The most common cause of VUFs is a previous cesarean section. We report a patient with a unique presentation of VUF, which is a protruded amniotic sac through urethra.
Case presentation
A 29-year-old woman in her fifth pregnancy presented to the emergency department at 24 weeks gestation with an abdominal pain and a sac protruding from vulva during urination thinking she was aborting. The pelvic examination revealed a thin-walled fluid-filled 5 cm × 5 cm- sized clear serous sac protruding from her urethra with no connection of the cervix or bleeding. Gynecologic examination showed partial cervical canal dilation without bleeding or leakage of amniotic fluid. Based on the clinical and ultrasound findings, we suspected a uterine and bladder rupture with the amniotic sac protruding from the urethra, therefor an emergency cesarean section was done. During the procedure, we addressed the fistula and The patient was discharged after a two-day recovery period.
Conclusions
Vesicouterine fistulae could interfere with many other disorders and should be considered as a differential diagnosis in every woman with a protruding amniotic sac.
Efficient preparation of the AKLT State with Measurement-based Imaginary Time Evolution
Authors: Chen Tianqi , Byrnes Tim 
Published: November 2023

Abstract

Quantum state preparation plays a crucial role in several areas of quantum information science, in applications such as quantum simulation, quantum metrology and quantum computing. However, typically state preparation requires resources that scale exponentially with the problem size, due to their probabilistic nature or otherwise, making studying such models challenging. In this article, we propose a method to prepare the ground state of the Affleck-Lieb-Kennedy-Tasaki (AKLT) model deterministically using an measurement-based imaginary time evolution (MITE) approach. By taking advantage of the special properties of the AKLT state, we show that it can be prepared efficiently using the MITE approach. Estimates based on the convergence of a sequence of local projections, as well as direct evolution of the MITE algorithm suggest a constant scaling with respect to the number of AKLT sites, which is an exponential improvement over the naive estimate for convergence. We show that the procedure is compatible with qubit-based simulators, and show that using a variational quantum algorithm for circuit recompilation, the measurement operator required for MITE can be well approximated by a circuit with a much shallower circuit depth compared with the one obtained using the default Qiskit method.

Abstract
To investigate the influence of fractures on the mechanical and seepage characteristics of rock masses, the fracture network within the rock mass is simplified as a single fracture. Under three-dimensional stress conditions, stress-seepage tests are conducted on inclined single-fracture sandstone rock samples at different confining pressures and water pressures. Three-dimensional surface scanners are used to scan and analyze the morphology of the fractures after the tests, studying the relationship between morphology and mechanical and seepage characteristics. The research results demonstrate that: Confining pressure significantly enhances the peak effective stress and effective crack damage threshold, while water pressure has the opposite effect. Confining pressure also has a positive impact on the elastic modulus and Poisson's ratio, the elastic modulus and Poisson's ratio nonlinearly increased with increasing confining pressure, which can be described by log function. With increasing pore pressure, the elastic modulus exhibited a slight initial increase, followed by a significant decrease after reaching 6 MPa. The Poisson's ratio exhibited a noticeable decrease with increasing pore pressure. A revised permeability calculation formula for a rough single fracture was proposed by introducing the fractal dimension, under three-dimensional stress conditions, permeability is a dynamic evolutionary process that can be divided into two modes. In Mode 1, the evolution of permeability can be divided into three stages: a stage of permeability decrease (stage I), a stage of initial increase followed by decrease (stage II), and a stage of rapid increase (stage III). In Mode 2, due to the absence of new flow channels, only stages I and II are observed. The negative correlation between the fractal dimension of fracture surface morphology and permeability confirms the validity of the permeability calculation formula.

Published: November 2023

Abstract

Grinding of silicon nitride ceramics has been seen the existence of processing problems such as low processing efficiency and high grinding forces. In response to the problem this paper mainly analyzes the processing mechanism of the laser-assisted grinding process, simulates the grinding process of a single abrasive grain grinding the surface of the silicon nitride microgroove through the coupled simulation of the smooth particle hydrodynamics (SPH), and finite element method (FEM), and analyzes the change of the material removal process with the grinding force and the depth of damage. The simulation results show that the grinding force and damage depth are significantly reduced when the abrasive grain cuts in the position of microgroove proximity due to the change of microstructure on the crack extension direction. An indentation experiment was carried out on silicon nitride ceramics, when the indenter was pressed in the closer position of the microgroove, the diagonal crack of the indentation would be extended to the side of the microgroove, which showed reasonable agreement with simulation results. It also proved that the laser heat source had a softening effect on the material. Two kinds of microgroove surfaces with different groove spacings were designed, and the laser-induced surfaces were subject to grinding experiments. The experimental results show that compared with the non-groove surface, the micro-grooved surface can significantly reduce the grinding force and improve the machining efficiency, and modifying the parameters of the grinding process can impact the effectiveness of laser-assisted grinding in reducing grinding force.

Abstract
This qualitative study aimed to gain a deep understanding of the spiritual needs of patients with advanced cancer. A qualitative study using semi-structured interviews was conducted. The interviews were audio-recorded, transcribed verbatim, and subjected to thematic analysis. Two researchers coded the interviews independently in NVivo 12 plus and developed major themes and subthemes by inductive and constant comparison. This study was conducted in the inpatient ward of a tertiary cancer hospital in Hunan Province, Chinese Mainland. Eligible participants with advanced cancer were recruited using the purposive sampling method. The sample size was determined by data saturation. All interviews were conducted face-to-face individually from May 2021 to July 2021. A total of 13 patients with advanced cancer patients were interviewed. Six themes were identified, namely being treated as normal and independent individuals, receiving and giving love, seeking inner peace, connecting with spiritual sources, finding meaning and purpose, and preparing for death. Different categories of spiritual needs of patients with advanced cancer were identified in this study. Healthcare professionals need to develop interventions that aim to meet patients’ spiritual needs.

Abstract

With the continuous development of intelligent technology, it is an inevitable trend for enterprises to accept and apply technology. But whether the technology adoption model is still effective in the mobile era is worth further study. This paper employs a quantitative meta-analysis of previous research on the technology acceptance model (TAM) use data of 81 article from 2006–2020. Results found that eight potential moderators related to the intrinsic attributes of the technology, the context of the study, and the characteristics of the participants, respectively. Research findings also show that all pairwise relationships of the variables in the focal part of TAM (5 variables and 10 relationships) are significant. Moreover, different moderation effects were found in these significant relationships and managerial implications are proposed.

Abstract

Live-Attenuated Vaccines (LAVs) stimulate robust mucosal and cellular responses and have the potential to protect against Respiratory Syncytial Virus (RSV) and Human Metapneumovirus (HMPV), the main etiologic agents of viral bronchiolitis and pneumonia in children. We inserted the RSV-F gene into an HMPV-based LAV (Metavac®) we previously validated for the protection of mice against HMPV challenge, and rescued a replicative recombinant virus (Metavac®-RSV), exposing both RSV- and HMPV-F proteins at its surface and expressing them in reconstructed human airway epithelium models. When administrated to BALB/c mice by the intranasal route, bivalent Metavac®-RSV demonstrated its capacity to replicate with reduced lung inflammatory score and to protect against both RSV and lethal HMPV challenges in vaccinated mice while inducing strong IgG and broad RSV and HMPV neutralizing antibody responses. Altogether, our results showed the versatility of the Metavac® platform and suggested that Metavac®-RSV is a promising mucosal bivalent LAV candidate to prevent pneumovirus-induced diseases.

Abstract
Nesidiocoris tenuis (Reuter) is an important omnivorous insect in tobacco fields. It is of practical scientific significance to regulate the population of N. tenuis by employing insect lure strategies with specific light spectra. In this study, the phototactic behavior of N. tenuis adults and nymphs to 15 kinds of monochromatic lights was examined. N. tenuis adults have a higher response rate and a longer displacement to different light spectra and different light intensities compared with nymphs. N. tenuis adults were more attractived by monochromatic lights at 628, 504, 568 and 589 nm among the 15 monochromatic lights. While N. tenuis nymphs were more attractived by monochromatic lights at 628, 549 and 577 nm, and there was no significant difference between the nymphs' response displacements to monochromatic lights except for red light at 628 nm and darkness treatments. The light intensity significantly affected the phototactic behavior of N. tenuis adults but not nymphs. These results suggested that insect traps with a red light at 628 nm, blue-green light at 504 nm, yellow-green light at 568 nm, and yellow-green light at 589 nm can be used to monitor and regulate N. tenuis population.

Published: November 2023

Abstract
Background
Uterine infections pose a significant problem for dairy farmers worldwide, leading to poor reproductive performance and economic losses. These infections, caused primarily by bacterial pathogens, can negatively affect cow fertility, milk production, and overall welfare. This study was conducted between December 2020 and December 2021 to gain insights into the incidence risk of uterine infections in postpartum dairy cows, isolate and identify bacterial causes and determine the antimicrobial susceptibility profile of the isolated bacteria. A total of 236 cows from 74 dairy farms were monitored from calving to 90 days postpartum, and aseptic uterine swab samples were collected from 40 cows with uterine infections. The samples were cultured, and the isolated bacteria were tested for antimicrobial susceptibility using the disk diffusion method.
Results
Out of 236 cows monitored during the postpartum phase, 45 (19.1%) were found to have contracted uterine infection, which could be either metritis or clinical endometritis. The incidence risk of metritis was 11.4% (n=27), while the incidence risk of endometritis was 7.6% (n=18). Of the 40 cultured swab samples, 29 (72.5%) had one or more bacteria isolated. The most commonly isolated bacteria were Escherichia coli(45%), coagulase-positive staphylococci (30%), and Klebsiella spp. (22.5%). Other bacteria, including Arcanobacterium pyogenes. (12.5%), Fusobacteriumspp. (12.5%), Enterobacter aerogenes (12.5%), coagulase-negative staphylococci (12.5%), Streptococcus spp. (7.5%) Salmonellaspp, (5%) Proteus spp (5%) and Pasteurella spp (2.5%) were also isolated. All of the isolated bacteria demonstrated resistance to at least one of the antimicrobials tested. Multidrug resistance was observed in E. coli, Klebsiella spp., A. pyogenes, and Fusobacterium spp. Gentamicin was found to be the most effective antimicrobial against all bacteria tested, while tetracycline was the least effective of all.
Conclusion
The study found that a significant proportion of cows in the population were affected by uterine infections and the isolated bacteria developed resistance to several antimicrobials. The study emphasizes the need for responsible use of antimicrobials to prevent the emergence of antimicrobial resistance. It also highlights the importance of raising awareness among dairy farmers to avoid the indiscriminate use of antibiotics and its consequences.

Published: November 2023

Abstract
Objective

Youth with anorexia nervosa inevitably interact with peers during inpatient care, which can affect their wellbeing. To help clinicians further improve care for these youth, this study aims to qualitatively research the experiences of social interaction among peers with anorexia nervosa in inpatient care.

Method

Semi-structured interviews were conducted with eleven adolescents and young adults with a history of inpatient care for anorexia nervosa. Their views and experiences surrounding social interaction among peers with anorexia nervosa in inpatient care were discussed comprehensively and processed through thematic analysis.

Results

Participants expressed corresponding views on social interaction among peers during admissions. Three main themes, including the positive and negative effects of social interaction, were defined: (1) the duality of social interaction, (2) the pressure to become the “best anorexic” and (3) multiple ways of interaction. Most participants noted a duality of positive and negative effects, which impacted their motivation for recovery.

Conclusions

Negative aspects of social interaction between patients with anorexia nervosa during admissions overshadow the positive aspects. This study provides insight in the benefits and risks of peer interaction and discusses the potential role of experts by experience and the importance for practitioners to acknowledge the impact of social media.

Published: November 2023

Abstract

Air pollution continues to be an international problem that endangers both human health and the environment. Over the past few decades, air pollution in Malaysia has emerged as a serious potential risk due to accelerated economic expansions and seasonal transnational pollution. Particulate matter atmospheric air pollutants in Malaysia have been identified as the most rampant and dominant in the air pollution index (API) amongst other criteria pollutants. The aim of this study is to investigate the statistical issues of long memory and volatility persistence in the level of particulate matter emission from 1 January 2011 to 31 December 2021 in fourteen continuous air monitoring stations of industrial, urban, and suburban categories using the main and partitioned series before and after the regimes of break. The Ordinary Least Square Cumulative Sum (OLS-based CUSUM) test was employed to partition the original series in each monitoring station based on its estimated break dates. The long memory parameter d alongside its standard error was estimated through three techniques namely, Geweke and Porter-Hudak, Fractionally Differenced Sperio, and Exact Local Whittle estimation. The issue of volatility persistence was investigated using the hybrid of the Autoregressive Fractionally Integrated Moving Average (ARFIMA) and Generalized Autoregressive Conditional Heteroskedastic (GARCH) model. The results confirm evidence of a mean-reverting form of long memory with a higher degree of persistence in the main series and volatility persistence in both the main and partitioned series that encountered structural break. This confirms that the data-generating process of particulate matter pollutant in Malaysia possesses true long memory and volatility persistence not spurious due to neglected structural break problem. Maximum emissions in all monitoring sites were observed during the pre-break regime except for Kota Kinabalu station where it occurred during the post-break regime. Most series were characterized by higher values of kurtosis and skewness implying the significant fluctuation and non-Gaussian behavior in the affected series.
Life cycle assessment of nutrient recovery from domestic wastewaters for sustainability of water resources and environmental benefits
Authors: Pausta Carla Mae , Kalbar Pradip , Saroj Devendra 
Published: November 2023

Abstract
Increase in anthropogenic activities proliferated the consumption of resources such as phosphorus; and increase the adverse environmental impacts especially eutrophication on water resources such as lakes. Nutrient recovery from domestic wastewaters to produce a fertiliser has been explored to address these challenges in the context of a sustainable circular nutrient economy. Life cycle assessment (LCA) was performed to holistically assess the impacts of integrating a nutrient recovery system on wastewater and water resource management using Laguna de Bay, Philippines as the geographical boundary. The inventory was developed based on the results of the emerging nutrient recovery reactor operations and the application of the recovered fertiliser on the agricultural crops. The LCA results for the proposed scenario showed environmental benefits of about 83.6% freshwater eutrophication, 102.5% terrestrial ecotoxicity, 26.9% water consumption, 100.7% mineral resource scarcity, while the global warming potential is 95.4% higher than the baseline scenario. Results imply policy review for septage management, system optimisation, and evaluation of alternative methods of wastewater management, in terms of life cycle thinking and sustainability across the globe.

Published: November 2023

Abstract
A comprehensive study on the variability and climatology of Arunachal Pradesh (study region) has been studied with the suite of automatic weather stations (AWS) and manual measured observations. Important meteorological variables such as air temperature (T), relative humidity (RH), wind speed (WS), wind direction (WD), and rainfall (RF) have been assessed, and explored the trend and variabilities for the study region. A very good correspondence is seen between two rainfall estimates (correlation coefficient value R = 0.77) over the study region, whilst during the monsoon season 10–20% higher R values were registered. The minimum (maximum) R value is 0.67 (0.92) at Ziro (Daporijo) station. Most of the stations in the study region exhibit significant monthly, seasonal, and diurnal variabilities in above mentioned meteorological attributes, whereas the diurnal variability is less significant in WD and RF. Spatial distribution of rainfall exhibits substantial season-to-season variation, where isolated (scattered) rainfalls are dominant during the cooler (warmer) seasons with values are almost 65% (40%). In addition, a higher percentage of fairly widespread (32%) and widespread rainfalls (8%) are noticed during the monsoon relative to other seasons, whereas dry percentage is higher during the cooler seasons. The frequency of heavy, very-heavy, and extremely heavy rainfall events is 2-times higher during with respect to the pre-monsoon season. Interestingly, the contribution of very light rain, light rain, and moderate rain to the total rainfall is ≈ 70%, whilst heavy, very heavy contributes about ≈ 30%. A significant negative trend in RF with a slope rate of -0.08 mm/year during the period 1976 to 2021, whereas the frequency of heavy and very-heavy rainfall events is increased with a slope rate of 1.28/year and 0.35/year, respectively for the study region.
