Published: November 2022

Abstract
To determine the diagenesis and evolution of the Cambrian DEPS (dolomite-evaporite paragenesis system) in the eastern Sichuan basin, the isotopic geochemistry characteristics of C, O, and fluid inclusions were studied. Four diagenetic systems were determined in the Cambrian DEPS based upon the hydrological system. These include the pore brine during the penecontemporaneous stage, sealed brine during the early diagenetic stage, compaction hot brine during the middle and late diagenetic stage, and mixed hydrothermal fluids involving deep thermal water during the later tectonic uplift stage. The character and source of fluids of various diagenetic stages and systems have a certain familiarity and inheritance features of development and evolution. However, fluids of various diagenetic stages and systems have different effects on the reservoirs. The diagenetic systems and manner of diagenesis are related to reservoir development closely. These include burial dolomitization and dissolution of sealed brine of the early diagenetic stage, and TSR (thermochemical sulfate reduction) and recrystallization of the mixed hydrothermal fluids involving deep thermal water during the tectonic uplift stage. Analyzing the basin structure indicates that a series of faults caused by the Cambrian detachment layer in the Eastern Sichuan Basin are the dominant factor controlling the spatiotemporal coupling relationship between the diagenetic systems and the reservoir in DEPS. The grain shoal subfacies control the regional distribution of the reservoir. During the early diagenetic stage, buried dolomitization helped with continued reservoir development, while TSR and recrystallization in the tectonic diagenetic stage improved reservoir quality by enhancing porosity and permeability. The Cambrian DEPS strata and the underlying Qiongzhusi Formation mud shale form a high-quality source-reservoir-caprock assemblage in the eastern Sichuan Basin.

Published: November 2022

Abstract
Background: Viral myocarditis (VMC) is an important factor leading to dilated cardiomyopathy (DCM), yet the molecular mechanism is far from elucidated. Autophagy has been proven to be associated with cardiomyopathies, but the role of autophagy in the progression from VMC to DCM is unclear and requires further study.
Methods: Common differentially expressed genes (CoDEGs) in DCM and VMC were screened from the related microarray datasets. Enrichment analysis and protein-protein interaction analysis were performed to identify key pathways and Hub Genes. The differentially expressed ARGs were used for receiver operating characteristic analysis to identify potential biomarkers. The expression of these identified genes was further verified in external datasets.
Results: A total of 134 CoDEGs were identified and these genes were mainly enriched in the pathways of “inflammatory response”, “response to virus”, “JAK-STAT signaling pathway”, and “PI3K-Akt signaling pathway”. The top 6 hub genes CCND1, STAT3, THBS1, CCL2, POSTN, IFIT2 and 11 Common differentially expressed ARGs BCL2L1, CCL2, CCND1, NAMPT, NRG1, S100A8, S100A9, SESN3, SNCA, STAT3, TUBA1C were identified. These genes had a similar expression pattern in DCM and VMC. Finally, in the external validation dataset, mice showed an enhanced inflammatory response and apoptotic response at the initial stage of coxsackievirus B3 infection and indicated DCM phenotype in the chronic stage of infection.
Conclusions: Inflammatory response and autophagy may be the vital biological pathways in the progression from VMC to DCM, and appropriate intervention of these processes may be a novel and potential therapeutic strategy.

Abstract
The neuro-ophthalmologic symptoms and retinal changes have been increasingly noticed after thalamic stroke and increasing evidence showing distinct alterations occurred in the vision-related functional network, while their intrinsic correlations are not completely understood. We aimed to explore the altered of functional network linking patterns and retina parameters, and their correlations with visual performance in thalamic stroke patients. Multi-modular functional connectivity (FC) was obtained with resting-state functional MRI. Optical coherence tomography-angiography was used to obtain retina parameters (retinal nerve fiber layer, RNFL; ganglion cell-inner plexiform layer, GCIP; superficial vascular complex, SVC; and deep vascular complex, DVC). Visual performance was measured through visual acuity (VA). Forty-six patients with first-ever unilateral thalamic stroke (mean age 59.74 ± 10.02 years, 33 males) were included. Significant associations were found in FC of Attention-to-Default Mode with SVC, RNFL, and GCIPL, and in FC of Attention-to-Visual with RNFL (p < 0.05). Both RNFL and GCIPL were significantly associated with the FC of Visual-to-Visual (p < 0.05). Only GCIPL was associated with VA (p = 0.038). In stratified analysis based on the disease duration of 6-month, distinct and significant linking patterns were displayed in muti-modular FC and various certain retina parameters; and their correlations with VA varied in each subgroup, respectively. These findings provide new insight into the understanding of the neural basis of the associations between brain network dysfunction and impaired visual performance in patients with thalamic stroke. Our findings are novel and might benefit targeted and individualized therapies in the future. Further in-depth studies are needed to verify our results.
On the regularity of generalized random spectral measures and their applications

Published: November 2022

Abstract
This paper is devoted to the regularity of generalized random spectral measures. First, we prove that every generalized random spectral measure defined on a locally compact metric space with values in a separable Hilbert space is regular. A solution of the Schrödinger-type random equation is obtained as an application. In the second part of this paper, we show that every finitely additive generalized random spectral measure defined on an arbitrary measurable space with values in a finite-dimensional Hilbert space is also regular. In addition, an random version of Jordan’s classical decomposition theorem for a matrix is provided.

Comparison of genetic variations between high- and low-risk Listeria monocytogenes isolates using whole-genome de novo sequencing
Authors: Ryu Jihye , Choi Yukyung , Yoon Yohan 
Published: November 2022

Abstract
In this study, genetic variations and characteristics of Listeria monocytogenes isolates from enoki mushrooms (23), smoked ducks (7), and processed ground meat products (30) were examined with respect to hemolysis, virulence genes, growth patterns, and heat resistance. The isolates that showed the highest pathogenicity were analyzed to obtain the whole-genome sequence, and the sequences were further analyzed to identify genetic variations in virulence, low-temperature growth-related, and heat resistance-related factors. All isolates had β-hemolysis and virulence genes (actA, hlyA, inlA, inlB, and plcB). At low temperatures, isolates with high growth (L. monocytogenes strains SMFM 201803 SD 1-1, SMFM 201803 SD 4-2, and SMFM 201804 SD 5-3) and low growth (L. monocytogenes strains SMFM 2019-FV43, SMFM 2019-FV42, and SMFM 2020-BT30) were selected. Among them, L. monocytogenes SMFM 201804 SD 5-3 showed the highest resistance at 60°C and 70°C. The strains SMFM 201804 SD 5-3 (high-risk) and SMFM 2019-FV43 (low-risk) harbored 45 virulence genes; 37 single nucleotide variants (SNVs) and 4 single nucleotide polymorphisms (SNPs; lntA, inlK, actA, and plcB) were identified between these two isolates. A comparison of 27 genes related to low-temperature growth revealed 14 SNVs and 4 SNPs (motA, ltrC, betL, and gbuB) between these two isolates; a comparison of the 21 genes related to heat resistance revealed 16 SNVs. These results indicate that the differences in the pathogenicity of L. monocytogenesSMFM 201804 SD 5-3 and L. monocytogenesSMFM 2019-FV43 are associated with the SNPs identified in virulence (lntA, inlK, actA, and plcB) and low-temperature growth-related (gbuB, betL, motA, and ltrC) genes.

Published: November 2022

Abstract
This work presents Chronos-V, a Many-Core System-on-Chip (MCSoC) that adopts abstract hardware modeling, executing the FreeRTOS Operating System (OS) at each processing element (PE). Chronos-V is a heterogeneous architecture with two regions: (i) General Purpose Processing Elements (GPPE), responsible for executing user applications; (ii) peripherals that provide IO capabilities or hardware acceleration to the system. Besides the standard goal of high-level models, design space exploration at early design stages with reduced simulation time, our goal is to advance the state-of-the-art in the MCSoC research field by proposing an architecture with hardware and software support for management techniques. As a case study, we present an ODA (Observe-Decide-Actuate) loop for thermal management, comparing it to a dark silicon patterning mapping in a platform with 196 PEs. Thermal maps show the benefits of using dynamic thermal management in terms of hotspot avoidance and temperature reduction.
Mineralogy, geochemistry and depositional environment of phosphates in the Pabdeh Formation, Khormuj anticline, SW of Iran
Authors: Haddad Fatemeh , Yazdi Mohammad , Behzadi Mehrdad , Yakymchuk Chris , Khoshnoodi Khalegh 
Published: November 2022

Abstract

Phosphate deposits are found in the Khormuj anticline at the end of the Folded Zagros Zone of Iran and are enriched in REE and trace metals. Field survey, petrography, X-ray diffraction and whole-rock geochemistry were used to determine the petrogenesis of these phosphate deposits and evaluate the mechanisms of trace metal enrichment. Khormuj anticline phosphate layers are hosted by carbonate rocks of the Pabdeh Formation (Lower Paleocene-Oligocene). The phosphatic layers are composed of phosphorus grainstone–packstone with microfossils and contains green glauconite. Whole-rock compositions of phosphates indicate a minimal detrital component and enrichment in U and HREE. These elements are not enriched in the limestone units that overlie and underlie the phosphate layers. Overall, the textures and trace element compositions of phosphate layers are interpreted to represent accumulation on a basin margin carbonate ramp, in the reduced and suboxic-to-anoxic zone, with low detrital input but occasional high-energy erosional events. Upwelling process played a fundamental role in the deposition of the sandy glauconite-bearing phosphate layers. Phosphate mineralization has syngenetic, diagenetic, and epigenetic components. Positive correlations between P2O5 and REE, U and other trace elements suggest that cation substitution into carbonate fluorapatite and not ion adsorption is the dominant mechanism for metal enrichment in these phosphates. REE patterns in these phosphate layers show strong negative Ce anomalies, positive Eu and Y anomalies and high La/Yb ratios (> 10). Yttrium versus (La/Nd)N ratios are in the seawater range and have been affected by diagenesis process. These elevated ratios suggest that the phosphates are relatively enriched in both the LREE and HREE. This enrichment is related to their marine origin, and weathering had no effect on the phosphate horizons. This research show that marine phosphates have high potential to preferentially fractionate the HREE and U and could represent a future source of these metals.

Published: November 2022

Abstract

Background: This study examined the factors influencing willingness-to-repurchase for each class of airline service, and integrate the constructs of service quality, satisfaction, and willingness-to-repurchase which were rooted on Engel-Kollat-Blackwell (EKB) model. The study focuses on the domestic and international arrival of passengers at Murtala Muhammed International Airport in Lagos and Nnamdi Azikwe International Airport in Abuja. Information was gathered from domestic and foreign passengers who had post-purchase experience and had used the airline's services more than once. The survey data were obtained concurrently from arrival passengers at two major international airports in Lagos and Abuja using an electronic questionnaire. The e-questionnaire targeted 606 respondents using purposive sampling and snowball sampling techniques. The data was analysed using the ordinal logit model and structural equatin model.
Results: From the 606 respondents, 524 responses were received but 489 responses were valid for data analysis and reporting and were obtained mostly from economy and business class passengers. The study found that the quality of 30-32 inches seat pitch; accessibility to digital TV during flight; allowance of 30kg luggage permission; and availability of online check-in 24 hours before the departing flight are the major service factors influencing willingness-to-repurchase for an economy ticket. Also, the quality of space for legroom between seats is wide (79 to 87 inches seat pitch) and the quality of seats can be converted into a fully flat bed; are the major service factor influencing willingness-to-repurchase economy tickets. Also, it was found that passengers' willingness to repurchase is influenced majorly by service quality, but not necessarily influenced by satisfaction.
Conclusions: The study identified the factors influencing willingness-to-repurchase for economy and business class tickets. It was concluded that seat comfort and baggage handling are most crucial in bth economy and business class tickets. From these findings, it was revealed that airlines will be able to have a better understanding of passengers’ willingness-to-repurchase airline services, especially for the economy and business fares concerning satisfaction perspectives, and can also be employed to improve business profitability and airline marketing capabilities.Recommendations were suggested for airline management based on each class.

Published: November 2022

Abstract
Video content analysis has a variety of application scenarios, including automatic content-based indexing and retrieval, video surveillance content description, automatic addition of dialogue subtitles for video, etc., which are urgently needed by enterprises and governments. These application scenarios currently require a large amount of manpower to label the specific content of the video, training the relevant personnel will cost a lot of resources, and the efficiency of manual labeling is low, if we can use computers to automatically analyze the video content will save a lot of costs for the relevant industries and bring revolutionary development. Traditional video analysis methods mainly rely on manually constructed features for matching to achieve the coarse classification of video, often dividing the video into a few categories or a dozen categories simply, which cannot be in line with the era of big data. Therefore, how to use the existing data resources and technical means to complete the content analysis of videos gradually becomes the focus of research. For the characteristics of large data volume and real-time of short videos, fast extraction of key frames containing the main information is the direction to focus on.
In this paper, we will consider the characteristics of short video multi-modality and fully exploit the information of each modality of short video. We focus on the semantic annotation methods for short videos. To address the problem that traditional video analysis methods cannot obtain high-value semantic information within the video, this paper first obtains key frames from the video that represent the main information of the video by key frame extraction technique. Based on migration learning, we use pre-trained models to improve the target detection and image description algorithms, extract the high-value regions in key frames, and perform semantic description. The research can better address the needs of short video content analysis and provide data basis for subsequent deep application scenarios.

Abstract

Although Culex species are considered to be equally affected by control measures targeting malaria vectors, there are still not enough evidences of the impact of interventions such as larviciding on these mosquito species distribution. The present study assessed the impact of a larviciding trial targeting malaria vectors on Culex mosquito species in the city of Yaoundé. A cluster randomized trial comparing thirteen treated clusters and thirteen untreated clusters was implemented. Data were collected at baseline and during larviciding intervention, from March 2017 to November 2020. The microbial larvicide VectoMax G was applied once every 2 weeks in intervention areas. Adult mosquitoes were collected using CDC light traps in both intervention and non-intervention areas and compared between arms. Globally, larviciding intervention was associated with 69% reduction in aquatic habitats with Culex larvae and 36.65% reduction of adult Culex densities in houses. Adult Culex densities were reduced both indoor (35.26%) and outdoor (42,37%). No change in the composition of Culex species was recorded. The study suggested a high impact of larviciding on Culex mosquito species distribution. The impact of the intervention could be improved if typical Culex breeding habitats including pit latrines were targeted.
High-efficiency sediment-transport requirements for operation of the Xiaolangdi Reservoir in the Lower Yellow River
Authors: Chen Cuixia , Fu Jian , Wu Moxi , Gao Xing , Ma Liming 
Published: November 2022

Abstract
Sediment accumulation is severe in the Lower Yellow River. Improving sediment-transport efficiency is an important way to save water resources. In this study, we analyzed the sediment-transport efficiency at different sediment concentrations and discharge levels using data from 306 non-overbank floods in the lower reaches of the Yellow River from 1960 to 2016. When the sediment concentrations were below 20 kg/m3, 60 kg/m3, and greater than 100 kg/m3, the clear water volumes for transporting sediment were above 50 m3/t, approximately 16 m3/t, and less than 10 m3/t, respectively. Given current scheduling, the Xiaolangdi Reservoir can lower its water level and increase non-overbank large water flows with an outflow discharge of &gt;3,000 m3/s when the incoming water flow has a sediment concentration of &gt;60 kg/m3. Mathematical modeling indicates that, for an incoming sediment load of 600 million tons in the Middle Yellow River, the average sediment-transport water volume at the downstream Huayuankou Station decreased by 27%, Optimized scheduling at the Xiaolangdi Reservoir could reduce the sedimentation in the downstream channel by 1.1 billion tons more than current scheduling, and extend the reservoir's sediment-trapping period by ten years. These findings can be applied widely in sandy rivers.
Dual-energy CT Virtual Non-Calcium Image is Beneficial for the Detection
of Non-displaced Knee Fractures
Authors: Fang Yijie , Liu Chaoran , Yu Wen , Zhan Yingying , Li Wenjuan , Liang Jianchao , Hong Guobin 
Published: November 2022

Background:
Early and accurate diagnosis is vital for avoiding the development of nondisplaced
fractures to displaced fractures. Dual-energy CT (Computed Tomography) can detect bone
marrow edema (BME), which may help to detect non-displaced fractures.

Aim:
To evaluate the value of DECT (Dual-Energy Computed Tomography) VNCa (Virtual noncalcium)
images for improving diagnostic performance and confidence in acute non-displaced knee
fractures.

Methods:
125 patients with clinical suspicion of knee fractures underwent both DECT and MR. Conventional
linear-blended CT and VNCa images were obtained from DECT. First, five readers with
varying levels of experience evaluated the presence of fractures on conventional linear-blended CT
and graded their diagnostic confidence on a scale of 1 to 10. Then BME with VNCa images was evaluated
and compared with MR. Finally, the VNCa images combined with conventional linear-blended
CT images were used to reassess the presence of fractures and diagnostic confidence. Diagnostic performance
and matched pair analyses were performed.

Results:
20 non-displaced knee fractures were detected. The consistency test of VNCa images and MR
by five radiologists showed Kappa values are 0.76, 0.79, 0.81,0.85,and 0.90,respectively. The diagnostic
performance of all readers was improved when using VNCa images combined with conventional
linear-blended CT compared with that with conventional linear-blended CT alone. Diagnostic confidence
was improved with combined conventional linear-blended CT and VNCa images (median
score:8,8,9,9, and 10, respectively) compared with conventional linear-blended CT alone (median
score:7,7,8,9, and 9).

Conclusion:
DECT VNCa images could improve the radiologists' diagnostic performance and confidence
with varying levels of experience in the detection of non-displaced knee fractures.
