A Study of the Funeral Rites Characteristics of “Gulbongjeongchwalto” in “Garakgukgi”
Authors:   The Research Of The Korean Classic, Hyeon Seung-hwan , Byeon Sook-ja
Published: June 2022

This study examines the nature of the funeral rites of “Gulbongjeong󰠀chwalto” presented in the story “Garakgukgi” from the Samgukeusa. “Garakgukgi” is the mythical story of the birth of the ‘Su-ro’. Since myths are transmitted along with rituals, the character and meaning of the myths of aqueducts can be understood concretely only when the ritualistic aspects appearing in the myths of aqueducts are clearly identified. In “Garakgukgi,” the portion pertaining to the birth of “Su-ro” is subdivided into two parts: before and after the birth of Su-ro. The birth of Su-ro signifies the emergence of a new king, while simultaneously signifying the death of the former ruler. In other words, the birth of Su-ro in “Garakgukgi”contains two events: the rite for the birth of a new king and the funeral rites of the former ruler. This is also illustrated through the placement of the tomb of the ancient ruler, “Jiseokmyo,” above that of “Gujibong,” and the rite for the birth of a Su-ro being performed on Gujibong. In this study, folklore materials handed down until today were used to investigate the characteristics of the funeral rites of “Gulbongjeongchwalto.” First, we examined the relationship between the custom of “Jejeol” and “Gulbongjeongchwalto” among the funeral methods handed down in Jeju Island today. Second, we discovered the tradition of singing and dancing to pray for the birth of a new life in the funeral process through the “Dasiraegi”, a funeral method in Jindo where the ancient funeral method called “double funeral” is handed down. “Gulbongjeongchwalto” and “Gujiga” performances consist of praying for the birth of descendants and the transmission of sacredness, raising the possibility that it would be passed down to future generations.
A Study on the Grotesque Features Represented in the ‘Fox Sister’ Folktale
Authors:   The Research Of The Korean Classic, Kim Jun-hee
Published: June 2022

This study investigates the “inconvenience” and “uncertainty” of the Fox Sister folktale through the concept of “the grotesque.” Beyond the visual grotesque of a specific scene, I tried to examine the grotesque in the mere existence of the fox sister and the grotesque that occurs in the tale itself. First, the parents’ wish for a daughter makes things coexist that cannot coexist, given that it is already a wish that defies the society in the story and the “common sense” of the transmitters. The parents’ wish for a daughter eventually becomes a curse that ruins the family, resulting in a conflict between the wish and the curse, as conveyed in the discourse. In addition, as the fox sister is an unnatural being, a hybrid of two heterogeneous species, she is a grotesque being that amplifies collisions with the human world in a state of incongruity rather than converging them, which leads to disharmony. The fox sister’s livestock predation embodies a grotesque in which familiar targets cause confusion. Distrustful of their grown-up sons, the parents also reveal their confusion between uncanniness and familiarity, and the fox sister’s brutal predation also reveals the clash of appearance and behavior and the grotesque of physical immoderation. The fox sister’s grotesque status reflects the character’s lack of specific aims. These grotesque interests and pleasures are related to “liminality” in that they do not pursue any value or high-level aesthetic consciousness. Furthermore, in the scene where the fox sister chases after her brother and is eliminated, the contradictory utterance of eating an inedible object (a person who is called “brother”) is repeated, and the grotesque of disharmony appears. Even if the fox sister is killed, the unresolved state remains in that the complete family cannot be recovered, which shows the “unresolved” in the grotesque.
Translating GPDRR UNDRR 2022, Sendai Framework, and the Bali Agenda for Resilience into Action: Mangrove-Nature Based Solutions and Local Wisdom in Mitigating Sea Level Rise Flood Disasters In Indonesia
Authors: Wibowo Andri
Published: June 2022

The recent global calamity of sea level rise and flooding is a major disaster. Some settlements on Java Island, Indonesia, have been reported to be sinking. Bedono Village is one village on the Central Java Coast that is vulnerable to sea level rise. Aside from the possibility of sea level rise, the calamity in this village is linked to prior mangrove degradation and fish pond expansion. This tragedy has displaced 78.63% of the population over a decade, and the remaining population is still surviving in the remaining lands. This study aims to investigate the effects of sea-level rise-related permanent inundation on the lives of the remaining residents in Bedono Village, with a focus on their adaptation and resilience methods. The results disclosed that remaining populations have taken active initiation by adopting multiple strategies that include structural prevention measures and nature based solution through mangrove reforestations. As a result based on mangrove assessment using Geographic Information Systems, mangrove cover increased from 1 ha in 2010 to 9.5 ha in 2012. This achievement has provided an alternative income through mangrove ecotourism. Women and multi stakeholder participation have also contributed to the implementation of adaptation strategy. Despite those significant achievements, the adaptation and resilience was challenged by lack of education and awareness towards sea level rise issues and their confounding disasters. The nature-based solution and local wisdom in Bedono Village is an example that is in line with GPDRR UNDRR 2022, the Sendai Framework, and The Bali Agenda for Resilience that ensures a whole-of-society approach to sea-level rise by ensuring that no one is left behind, creating an inclusive environment, and promoting gender.

Authors: Szczerska Malgorzata
Published: June 2022

Temperature measurements are of great importance in many fields of human activities, including industry, technology, and science. For example, obtaining a certain temperature value or a sudden change in it can be the primary control marker of a chemical process. Fiber optic sensors have remarkable properties giving a broad range of applications. They enable continuous real-time temperature control in difficult-to-reach areas, in hazardous working environments (air pollution, chemical or ionizing contamination), and the presence of electromagnetic disturbances. The use of fiber optic temperature sensors in polymer technology can significantly reduce the cost of their production. Moreover, the installation process and usage would be simplified. As a result, these types of sensors would becoming increasingly popular in industrial solutions. This review provides a critical overview of the latest development of fiber optic temperature sensors based on Fabry-Perot interferometer made with polymer technology.

The catalytically active vanadium-containing system on γ-Al2O3 was studied using a wide range of physical and chemical methods depending on the synthesis conditions. It is shown that the vanadium-containing system includes several complexes with different thermal stability and catalytic activity. Low-active complexes are destroyed with the formation of more active ones based on V2O5 oxide as the temperature of heat treatment increases. It can be assumed that the V2O5 oxide has the decisive role in its catalytic activity. It was concluded that the vanadium-containing catalytic system on aluminum oxide, in the studied temperature range, is thermal stable and shows high activity not only in the reduction of nitrogen oxides but also in the oxidation of hydrocarbons (even of the most difficult ones, such as oxidizable methane). These properties of the system make it quite promising in the field of application for purification of exhaust gases of motor transport and industrial enterprises from environmentally harmful components as well as for understanding the mechanism of the action of catalysts in these processes, which is very important for solving the problems of decarbonization and achieving carbon neutrality.

Published: June 2022

Case:

A 73-year-old man with a medical history significant for renal cell carcinoma (RCC) presented with widespread osseous metastases and imaging suspicious for RCC metastasizing to a lipoma interdigitated within the right vastus lateralis. The patient's pathological fractures were surgically addressed, and the lipoma excised. Final histology revealed a thigh lipoma involved by metastatic RCC without direct extension.

Conclusion:

Tumor-to-tumor metastasis is a rare occurrence, with RCC typically being the most common “recipient” tumor. This is the first case to the best of our knowledge of RCC metastasizing to a lipoma, highlighting a rare phenomena in a patient with metastatic disease.
Fatal Fulminant Fat Embolism Syndrome in Adult Spine Deformity Surgery
Authors: Mohar Janez
Published: June 2022

Case:

A 68-year-old woman was scheduled to undergo elective correction of coronal spinal malalignment after a previous lumbar instrumented fusion. In the final stages of the operation, the patient became hemodynamically unstable. Her systemic condition worsened subsequently, leading to cardiac arrest followed by unsuccessful resuscitation. An autopsy revealed a massive fat embolism in the lungs.

Conclusions:

The diagnosis of fat embolism syndrome (FES) is clinical, and treatment is supportive, with no clinical or investigative criteria that can facilitate diagnosis in a patient under general anesthesia. This is the first description of FES in adult spinal deformity surgery.

Published: June 2022

Case:

A 77-year-old woman with bilateral symptomatic atypical femoral fractures (AFFs) and severe anterolateral bowing due to long-term bisphosphonate administration was treated using stainless elastic intramedullary nails. Weight-bearing pain disappeared immediately after surgery. Radiographs obtained 1 year postoperatively showed fracture healing.

Conclusion:

Although intramedullary nail insertion has been recommended for symptomatic incomplete AFFs, in cases of severe bowing, rigid nail insertion was often challenging, and the complication rates were higher than those with mild bowing. The advantage of our method is easy insertion, suggesting effective treatment.

Published: June 2022

Pauli spin blockade (PSB) can be employed as a great resource for spin qubit initialisation and readout even at elevated temperatures but it can be difficult to identify. We present a machine learning algorithm capable of automatically identifying PSB using charge transport measurements. The scarcity of PSB data is circumvented by training the algorithm with simulated data and by using cross-device validation. We demonstrate our approach on a silicon field-effect transistor device and report an accuracy of 96% on different test devices, giving evidence that the approach is robust to device variability. The approach is expected to be employable across all types of quantum dot devices.
Bile Microbiome in Patients with Recurrent Common Bile Duct Stones and correlation with the Duodenal Microbiome
Authors: Lee Jungnam , Park Jin-Seok , Bae Jaewoong , Lee Sohee , Hwang Yeonju
Published: June 2022

Background
Common bile duct (CBD) stone recurrence is a common late adverse event after CBD stone treatment. In this preliminary study, we compared the bile fluid and duodenum microbial profiles of patients with or without recurrent CBD stones to identify risk factors associated with recurrence.
Methods
Bile fluid samples of 47 consecutive patients who underwent ERCP for biliary diseases were subjected to microbiome analysis. Nineteen patients were stone recurrent (SR), and 28 patients were non-stone recurrent (NSR). Paired samples (duodenum biopsy tissue and bile fluid samples) from 5 SR patients were used to compare microbiome compositions in the biliary system and duodenum. In addition, we compared the microbiome compositions of these duodenal tissue samples with those 12 controls (gastric ulcer patients without recurrent CBD stones).
Results
Enterococcaceae_unclassified and enterococcus were more abundant in bile fluid in the SR group than in the NSR group (p = 0.002 and p = 0.003, respectively). A comparison of the microbiome compositions of duodenum tissue and bile fluid samples of the 5 recurrent CBD stone patients revealed proteobacteria compositions were almost identical from the phylum to genus level. In these 5 patients, alpha and beta diversities were no different in bile fluid and duodenal tissues. Furthermore, a comparison of the microbiome compositions of duodenal mucosa in patients with recurrent CBD stone patients (n = 5) and controls (n = 12) revealed significant differences between microbiome compositions.
Conclusions
Enterococcus seems to contribute to CBD stone development. Furthermore, our results indicate retrograde migration of the duodenal microbiome may contribute to bile microbiome alterations. We recommend that more research be conducted to confirm this hypothesis.

Published: June 2022

Broadband access is an essential social determinant of health, the importance of which has increased due to the ongoing COVID-19 outbreak. Using data from the City Health Dashboard and American Community Survey, we found that in 2017, 30% of urban households in 766 large US cities still had no access to high-speed broadband internet. After controlling for household income, broadband access in majority Black and Hispanic neighborhoods was 10-15% lower than in White or Asian majority neighborhoods. In 2019, lack of broadband access in urban households decreased to 28%, but substantial broadband disparities still persist in these cities.

Published: June 2022

Gastrointestinal nematodes (GIN) are a major threat to health and welfare in small ruminants worldwide. Teladorsagia circumcincta is a nematode that inhabits the abomasum of sheep, especially in temperate regions, causing important economic losses. Given that T. circumcincta and microbiome share the same niche, interactions between them and the host are expected. Although it is known that within a sheep breed there are animals that are more resistant than others to infection by GIN, it is not known if the microbiome influences the phenotype of these animals. Under this condition, 12 sheep were classified according to their cumulative faecal egg count (cFEC) at the end of a first experimental infection, 6 as resistant group (RG) and 6 as susceptible group (SG) to T. circumcincta infection. Then, all sheep were experimentally infected with 70,000 L3 of T. circumcincta and at day 7 days post-infection were euthanized. At necropsy, gastric mucosa and gastric content from abomasum were collected to extract bacterial DNA and sequence V3-V4 region from 16S rRNA gene using Ilumina technology. After bioanalysis performed, results showed that α-diversity and β-diversity remained similar in both groups. However, resistant phenotype sheep showed a higher number of bacteria butyrate-fermenting species as Clostridium sensu stricto-1 (abundance in RG: 1.29% and in SG: 0.069%; p = 0.05), and Turicibacter (abundance in RG: 0.31% and in SG: 0.027%;p = 0.07) in gastric content but also Serratia spp in gastric mucosa (abundance in RG: 0.12% and in SG: 0.041%; p = 0.07). A trend towards a significant negative correlation between cFEC and Clostridium sensu stricto-1 abundance in gastric content was detected (r = -0.537; p = 0.08). These data suggest that microbiome composition could be another factor that influence in the development of the resistant phenotype modifying the interaction with the host and the in last instance affecting the individual risk of infection.
Research on Competition and Cooperation of Central Ports in the Guangdong-Hong Kong-Macao Greater Bay Area Based on the Multi-group Lotka-Volterra Model
Authors: Wang Xuanfei , Liang Shan , Liao Zhenjie
Published: June 2022

The construction of the Guangdong-Hong Kong-Macao Greater Bay Area requires the establishment of a comprehensive port cooperation mechanism. Coordination is key to port integration. This paper establishes a multi-group Lotka-Volterra model based on the theory of competition and cooperation to study the evolution of the relationships among Hong Kong Port, Shenzhen Port, and Guangzhou Port. The results show that the three major ports have predator-prey roles and form a symbiotic competition and cooperation ecological pattern. The extended Hotelling model is established to study the central ports’ spatial differences; the results show that whether it is the central port cooperation body or the entire central port group, the gains from Shenzhen Port–Guangzhou Port cooperation are greater than between either and Hong Kong Port for Guangdong-Hong Kong-Macao Greater Bay Area’s container business. The biggest competitor to Hong Kong Port in the container business is Guangzhou Port. Hong Kong Port will gain more from cooperation with Shenzhen Port and should strengthen such cooperation. The study provides quantitative support and reference for positioning the strategic development of the high-end shipping business in Hong Kong Port, the pilot free-trade port in Shenzhen Port, and the exploration of the Shenzhen-Hong Kong composite port, Guangzhou Port’s comprehensive shipping hub.
The influence of a coupling nonlinear spring-mass system on dynamic responses of a generally restrained double-beam structure
Authors: Zhao Yuhao , Du Jingtao , Chen Yilin , Liu Yang
Published: June 2022

On various engineering occasions, complex structures are typically simplified as several-beam structures jointed by coupling devices. Coupling devices can be divided into rigid and elastic coupling cases. The elastic coupling device is regarded as a spring-mass system. When the coupling device is high-elastic, the equivalent stiffness of the elastic coupling device exhibits nonlinear characteristics. The existing studies related to double-beam structures are mainly limited to the linear case. There are few studies investigating the dynamic responses of the double-beam structure jointed by a nonlinear spring-mass system. Considering the engineering practice, this study establishes the vibration analysis model of a generally restrained double-beam structure coupled with a nonlinear spring-mass system. The governing equations of the double-beam structure and the coupling nonlinear spring-mass system are derived through the generalized Hamiltonian principle and the variational procedure. The Galerkin truncation method (GTM) is employed to predict the dynamic response of such a double-beam structure. On this basis, the influence of the coupling nonlinear spring-mass system on dynamic responses of the double-beam structure is investigated. It can be concluded that the GTM has good stability and correctness for predicting dynamic responses of the double-beam structure with a coupling nonlinear spring-mass system. Dynamic responses of such a double-beam structure are sensitive to their initial calculation values. Suitable coupling nonlinear stiffness beneficially influences vibration suppression and significantly changes the kinetic energy transfer characteristics of the double-beam structure. Additionally, single-frequency responses can be transferred into multi-frequency responses under a suitable coupling nonlinear stiffness.
Comprehensive analysis of survival related ceRNA regulatory net- work in Cholangiocarcinoma
Authors: Gao Xiaoling , Zhang Wenhao , Jia Yanjuan , Xu Hui , Zhu Yuchen , Pei Xiong
Published: June 2022

Background: Cholangiocarcinoma (CCA) is a highly malignant disease with poor prognosis. Its occurrence and development mechanisms remain unearthed. The ceRNA network describes the relationship between cancer-related RNAs and reveals the potential regulatory mechanism in CCA pathogenesis. Method: The genome transcriptome dataset of CCA was downloaded from the TCGA database. Differential expressional and survival analysis were performed by "edgeR" and "survival" package in R soft (|logFC|≥2, adjusted P-value<0.05), respectively. The interaction of miRNA-lncRNA and miRNA-mRNA were predicted by the miRanda and TargetScan. The ceRNA networks were visualized by the cytoscape 3.7. The heat maps, PCA analysis, KEGG and GO enrichment analysis, and prognostic model were performed and visualized on the online platform. Result: 6837 DEmRNAs, 2771 DElncRNAs, and 173 DEmiRNAs were screened out and ceRNA was constructed consisting of 434 lncRNA-miRNA pairs and 284 miRNA-mRNA pairs with 200 lncRNAs, 21 miRNAs and 245 mRNAs. Moreover, 3 lncRNAs (AC090772.1, LINC00519 and THAP7-AS1) and their downstream mRNAs (MECOM, MBNL3, RCN2) were significantly related to survival time. Finally, four key networks associated with survival-related DElncRNAs and DEmRNAs (LINC00519/hsa-mir-22/MECOM, THAP7-AS1/hsa-mir-429/MBNL3, THAP7-AS1/hsa-mir-155/MBNL3 and THAP7-AS1/hsa-mir-155/RCN2) were obtained. The disease-specific survival (DSS) prognostic model was established and showed the predictive ability based on these candidate ceRNA networks (AUC=0.66~0.83). Conclusion: The study provided a novel ceRNA network related to survival time that had broaden our understanding of the regulatory mechanisms in the development of CCA, as well as served as potential targets for drug development to improve the prognosis of CCA.

Published: June 2022

The aim of the present experiment was to study the feasibility of supplementing a multi-strain probiotic (MSP, Bacillus subtilis and Lactobacillus plantarum) culture by the technology of post-spraying, the viability of the MSP in the post-spraying and storage process, growth performance, digestive enzyme activity, antioxidant capacity and intestinal microbiota of grass carp were assessed. Grass carp (41.4 ± 1.8 g) was fed with a basal diet (control group) and the MSP-basal diet containing 105 CFU/g (T1 group) or 106 CFU/g (T2 group) probiotics supplemented by the post-spraying technology in 9 cages (100 fish/ cage) for 6 weeks. The population of the probiotics was appraised (Log CFU) for 30 days. The results revealed that the viability of the B. subtilis and L. plantarum was 98.14% and 98.09% in the process of post-spraying technology, 99.13% and 99.10% after 30 days of storage respectively. The diet supplemented MSP significantly improved the percent weight gain (PWG), specific growth rate (SGR) and survival rate (SR) of grass carp, and decreased the feed conversion ratio (FCR) (p < 0.05). Additionally, a significant improvement on the digestive enzyme activity and antioxidant capacity was shown in the MSP groups (p < 0.05). Meanwhile, the MSP beneficially modulated the intestinal microbiota of grass carp. Overall, these results indicated that the post-spraying technology supplied a feasible and potential way to supplement the liquid probiotics culture in the aquatic feedstuff industry with high viability to promote the liquid probiotics application.
Combined clustered scan-based metal artifact reduction algorithm (CCS-MAR) for ultrasound-guided cardiac radioablation
Authors: Puvanasunthararajah Sathyathas , Saskia Saskia , Wille Marie-Luise , Fontanarosa Davide
Published: June 2022

Cardiac radioablation is a promising treatment for cardiac arrhythmias, but accurate dose delivery can be affected by heart motion. For this reason, real-time cardiac motion monitoring during radioablation is of paramount importance. Real-time ultrasound (US) guidance can be a solution. The US-guided cardiac radioablation workflow can be simplified by the simultaneous US and planning computed tomography (CT) acquisition, which can result in US transducer-induced metal artifacts on the planning CT scans. To reduce the impact of these artifacts, a new metal artifact reduction (MAR) algorithm (named: Combined Clustered Scan-based MAR [CCS-MAR]) has been developed and compared with iMAR (Siemens), O-MAR (Philips) and MDT (ReVision Radiology) algorithms. CCS-MAR is a fully automated sinogram inpainting-based MAR algorithm, and it does not depend on access to sinograms from CT scanners. The key step of CCS-MAR is the creation of an artifact-free combined clustered scan which is then used in the normalized MAR method to reduce the metal artifacts. To evaluate the robustness of CCS-MAR, conventional CT scans and/or dual-energy CT scans from three anthropomorphic phantoms and transducers with different sizes were used. The performance of CCS-MAR for metal artifact reduction was compared with other algorithms through visual inspection, artifact magnitude calculation, and HU value restoration evaluation. The results of this study show that CCS-MAR effectively reduced the US transducer-induced metal artifacts and that it improved HU value accuracy more or comparable to other MAR algorithms. These promising results justify future research into US transducer-induced metal artifact reduction for the US-guided cardiac radioablation purposes.
Geology and Structure of Uru-Ugworji Diorite Lokpanukwu, Southeastern Nigeria
Authors: Nwosu Obinnaya Chikezie Victor , Ibe Kalu Kalu
Published: June 2022

Geological, Geophysical and Core analyses were carried out in Uru Quarry site, Lokpaukwu located between latitudes 5056.149’N and 5056.193’N and between 7028.312’E and 7028.356’E. Geologic formations that underlie the study area are the Asu River Group and Eze-Aku Formation. Five rock units are found in the area; siltstone found in the eastern portion of the study area and occurs as a “CAP” on the shale. The middle portion of the study area is underlain by shale, and it occupies one-half of the study area. Calcareous sandstone occupies the Western portion of the area. The Eastern portion is Dolerite which is the basic rock matter that cuts across siltstone and shale. Iron is found with the basic rock matter in the area. Geological studies on the study area indicate the five rock units and their outcrops; 2 geological sections were interpreted. Geophysical methods using the Electrical Resistivity Sounding of Schlumberger indicates the West, Northwestern and Central portions of the area have thick sedimentary sequence and the Eastern portion of the study area is made up of igneous body which is the main part of this project; the basic rock having a high resistivity value, followed by sandstone, siltstone and shale with moderate to low resistivity. Core analysis carried on eleven core samples obtained at the Eastern portion of the study area shows that the core samples consist of the rock unit found in the area. In the Obichioke area were nine core samples consisting of rock units too. Core data analysis of the study area indicates the location and kind of rocks found in the study area; mineral present and the strength of the rock units found in Lokpaukwu area. Geologic mapping shows that a major fault occur in the area separating the viable Uru end from the non-viable Obichioke lot. The fault trace shows primarily recrystallization (alcitic matter). Thus, it is suggested that similar studies be made before the establishment of quarries whenever igneous (basic) units occur.
Fractional-order multivariable adaptive control based on a nonlinear scalar update law
Authors: Yan Fang , Hou Xiaorong , Tian Tingting
Published: June 2022

In this article, a new fractional-order model reference adaptive control (FOMRAC) framework based on a nonlinear scalar update law is proposed for a fractional-order multivariable system with parameter uncertainty. The scalar update law does not change as the input-output dimension changes. Compared with the existing results, the main advantage of the proposed adaptive controller is that only one parameter online updating is needed such that the control scheme is structurally simple and computationally inexpensive. We further show that all signals in this adaptive scheme are bounded and that the mean value of the squared norm of the error converges to zero. Two illustrative numerical examples are presented to test the efficiency of the proposed architecture

Published: June 2022

Background
Reliance on P-value of significance in clinical trials is a source of debate because of misconceptions and misinterpretations associated with it. Bayesian methods are suggested as an alternative approach. As randomized-controlled trials (RCTs) are essential in generating research evidence, we investigated the change in the use of P-values and Bayesian analysis and the clustering of P-values at key significance levels in child health RCTs published in 2007 and 2017.
Methods
We searched Cochrane Central Register of Controlled Trials to identify random samples of child health RCTs published in 2007 (n = 300) and 2017 (n = 300). Data on trial characteristics and analytic approaches were extracted. We analyzed the 600 RCTs using the frequentist and Bayesian methods. The change in the proportion of trials reporting P-values and Bayesian analyses was assessed using Pearson/Fisher Exact tests and non-informative Dirichlet priors.
Results
Of 600 RCTs, 535 (89%) used frequentist methods only versus 65 (11%) that included some Bayesian methods. Only 2 of the 65 trials used Bayesian inferential statistics. The use of frequentist methods decreased from (273, 91% to 262, 87%) while the inclusion of Bayesian analysis slightly increased from (27, 9% to 38, 13%) between 2007 and 2017. Although most RCTs were from Europe (172, 29%) and North America (133, 22%), the increase in proportion of trials by continent was most in Asia (mean difference (MD) = 0.14, 95% credible interval (CI) 0.08–0.20) with posterior probability (PP) of 1.00. Parallel (487, 81.2%) and cluster (58, 9.7%) RCTs were the most common RCT types but the increase in cluster RCT (0.06, 95%CI 0.02–0.11, PP = 0.99) was more than any other RCT types over 10 years. We found clustering of P-values at the significance level of 0.05 (437, 72.8%), which increased between 2007 (209, 69.7%) and 2017 (228, 76%). The smallest P-value reported in this review was 0.0001 (1, 0.2%).
Conclusions
The statistical framework in child health RCTs has not changed from the frequentist methods that is based on P-values with an unexplained clustering at the significance level of 0.05. Bayesian methods may increase the confidence in interpretation of results of RCTs

Published: June 2022

Lakes are one of the most important resources for human like tourism, irrigation and drinking. Hence lake water quality should be regularly monitored for better management of the water resources. The aim of the study was to assess the current physicochemical property and the trophic status of lake Hayq which is located in the norther part of Ethiopia. Using non probability with judgmental sampling method, eighteen water samples at six sampling sites were collected in pre wet season (May), wet (July) and post wet (December) of 2020. Both on site and laboratory analyze of water quality parameters were conducted. Data analyses used descriptive statix10 to summarize and analyze of the data, T-test for temporal variation and, GIS (IDW) interpolation was used for analyzing of spatial variation. The result shows, the mean value of temperature 27.3C°, turbidity 7.8NTU, SD 1.3m, pH 8.5, EC 908.83µs/cm, TDS 464.8mg/L, TP1.3mg/L, TN 21.84mg/L, DO 7.69mg/l, COD 13.33mg/l, BOD 6.40 mg/L and chlorophyll a 35µg/L. The comparison of result with fresh water guideline (EPA/USEPA) T, DO, pH and EC with in permissible limits and TDS, Tur, TP, TN, COD, BOD and CH-a was above permissible limits. The temporal variation of pollutions was statistically significant (p<0.05) in average dry and wet. GIS IDW interpolation shows significant color difference in spatially variation of parameters along lake shore. Trophic State index was TSI 76.7 and TLI 67.5 that indicates higher eutrophic level. Therefore, providing terrace, buffer zone, and silt trap are needed to reduce the overflow of pollution.

The 100-m X-ray Test Facility of the Institute of High Energy Physics (IHEP) was initially proposed in 2012 for the test and calibration of the X-ray detectors of the Hard X-ray Modulation Telescope (HXMT) with the capability to support future X-ray missions. The large instrument chamber connected with a long vacuum tube can accommodate the X-ray mirror, focal plane detector and other instruments. The X-ray sources are installed at the other end of the vacuum tube with a distance of 105 m, which can provide an almost parallel X-ray beam covering 0.2∼60 keV energy band. The X-ray mirror modules of the Einstein Probe (EP) and the enhanced X-ray Timing and Polarimetry mission (eXTP) and pay-load of the Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) have been tested and calibrated with this facility. It has been also used to characterize the focal plane camera and aluminum filter used on the Einstein Probe. In this paper, we will introduce the overall configuration and capability of the facility, and give a brief introduction of some calibration results performed with this facility.

Background and Purpose: Nearly half of patients who undergo mechanical thrombectomy (MT) do not experience a favorable outcome. The association between blood pressure fluctuation and clinical outcomes after successful MT is controversial. We evaluated the influence of blood pressure variability (BPV) on the clinical outcomes of stroke patients with large vessel occlusion (LVO) who underwent successful recanalization after MT.Methods: Patients with anterior circulation LVO stroke who underwent successful emergency MT (modified Thrombolysis in Cerebral Infarction, mTICI≥2b[A1] ) at the Shanghai Tenth People's Hospital of Tongji University from 2017 to 2021 were enrolled. Multivariate logistic models were used to investigate the association between BPV (mean arterial pressure [MAP] assessed using the standard deviation [SD]) and clinical outcomes. The primary outcome was 90‐day modified Rankin Scale scores (mRS), and the secondary outcomes were 30-day mortality and symptomatic intracranial hemorrhage (sICH). [A2] Results:A total of 458 patients [A3] (56.8% men), with a mean age of 72 ± 11 years, were enrolled. Among them, 207 (45.2%) patients had unfavorable functional outcomes (mRS score 3–6) at 90 days, 61 (13.3%) patients died within 30 days, and 20 (4.4%) patients had sICH. In a fully adjusted model, BPV was associated with a higher risk of a 90-day mRS score of 3–6 (P=0.04), 30-day mortality (P<0.01), and sICH (P<0.01). [A4] A significant interaction between MAP SD and rescue futile recanalization treatment was observed (P<0.01).Conclusions:Among patients with LVO stroke who underwent successful recanalization, higher BPV was associated with worse functional outcomes, especially in those who underwent rescue treatment.

Purpose
Efficacy of near-infrared spectroscopy monitoring of paraspinal collateral network (cnNIRS) has been shown to provide additional safety in extensive aortic repair. Better understanding of available cnNIRS monitoring systems regarding differences in performance for this specific purpose is required.
Methods
Two systems (FORE-SIGHT®, CAS Medical Systems, USA and INVOS™ 5100C; Medtronic, Ireland) used at 4 paravertebral levels (mid and lower thoracic, upper and lower lumbar) were compared in an acute large animal model during three different experimental sequences mimicking relevant clinical scenarios: segmental artery (SA) occlusion by (1) open-access clip-occlusion (n = 7), (2) endovascular coil-embolization (n = 9) and distal circulatory arrest via (3) aortic cross-clamping (n = 9).
Results
Significant differences in oxygenation measurements between devices were observed only at the lower thoracic level during SA clipping and aortic cross-clamping (p < 0.001). During SA clipping, FORE-SIGHT and INVOS demonstrated reduction to 85% and 72% of baseline values after occlusion of the mid-thoracic region, with mean differences between devices varying from 12.9 to 20.6% (p > 0.05) throughout the experiment. In the aortic cross-clamp sequence, reduction of values was observed in both devices, with FORE-SIGHT having less pronounces decrease during cross-clamping compared to INVOS (mean differences 1.0-14.7%, p > 0.05), and slower response to reperfusion after declamping (72 to 84% within 1 minute in FORE-SIGHT and 57 to 99% in INVOS).
Conclusion
Both devices provide similar cnNIRS monitoring applicability at mid-thoracic, upper and lower lumbar levels. INVOS seems to have a more rapid and pronounced response to open SA sequential occlusion and aortic cross-clamping at the lower thoracic level.

The study was carried out to determine the effect of debittering methods on the chemical, physiochemical and shelf-life of flours produced from dibittered orange seeds. The orange seeds were removed manually from sweet orange fruits, soaked in water for 12 hours and then boiled at 100 0C for 30, 60, 90, 120 and 150 min, respectively. The boiled seeds were dehulled manually, ground, and a portion defatted with absolute ethanol, milled and sieved. The various defatted and undefatted orange seed flours were analyzed for chemical and physiochemical properties. The orange seed flours contained 7.53 % – 54.58 % protein, 3.94 % – 47.32 % fat, 2.55 % – 24.58 % crude fiber, 2.03 % – 6.89 % ash, 2.53 % – 61.27 % moisture content, 5.62 – 58.47 % carbohydrate, 78.10 – 295.22 oxalate, 0.0 – 196.00 Hu/mg haemaglutinin, 0.0 – 86.45 mg/100g tannins, 128.54 – 303 mg/100g pytate, 1.51 – 1.98 g/g water absorption capacity, 1.060 – 1.625 g/g oil absorption capacity, 67 – 75 % dispersibility, 14.44 – 42.00 S wetability, 59.24 – 70.42 0C gelation temperature, 5 – 20 g least gelation capacity, 0.40 – 0.69 g/cm3 and bulk density. Orange seed waste maybe transformed in to useful product due to its nutritional quality to alleviate malnutrition and produce better quality products. Substituting orange seed flour with wheat flour will improved the protein, minerals, vitamin, fat and fiber content of the composite flour.
Urban scale risk assessment including SSI and site amplification
Authors: Amendola Chiara , Pitilakis Dimitris
Published: June 2022

Large-scale risk analysis is typically performed considering existing fragility curves, calculated in most cases without adequately accounting for local site amplification (SA) and soil-structure interaction (SSI) effects. Nevertheless, foundation flexibility and local site effects may lead to a substantial margin of fragility or loss estimates, especially for structures resting on soft soil. Including these effects on the city-scale vulnerability analysis is challenging due to the entailed complexity of defining the whole interacting urban system. We propose a novel framework for the fragility assessment of structures considering the influence of SSI and local site amplification effects, suitable for large-scale applications. The applicability of the proposed approach is based on globally available data regarding the soil, the foundation, and the building portfolio. Site amplification is considered directly in the resulting fragility curves using site response analyses. An improved taxonomy is adopted to make the approach implementable in the OpenQuake software, introducing VS,30 as a proxy for the site and SSI effects. Finally, following the performance-based earthquake engineering framework, the outcomes of the methodological framework are adopted to estimate the nominal probability of failure for selected building classes belonging to the majority of structural types of the city of Thessaloniki, Northern Greece. The main findings demonstrate that the conventional way of calculating fragility curves may lead to an incorrect seismic risk evaluation, especially in soft soil formations.
The effect of station density in geostatistical prediction of air temperatures in Sweden: a comparison of two interpolation techniques

Sparse coverage of meteorological stations reporting climatic variables is a key challenge in generating spatially continuous temperature data set because sparse coverage of stations is known to introduce uncertainty in the interpolation of temperature and related data sets. Consequently, development of methods to improve the accuracy of interpolated surfaces based on sparsely distributed point measurements has been an area of active research in geospatial studies. In this study, we assessed and compared Empirical Bayesian Kriging (EBK) and EBK Regression Kriging (EBKRP) interpolation techniques in terms of their accuracy under varying sampling density scenarios using monthly maximum temperature normals (1991–2020) for the entire area of Sweden as a case study. The EBK family of geostatistical interpolation methods are touted to have a generally higher interpolation accuracy over other interpolation techniques especially when sample data is sparse or locally non-stationary. Here, seven sampling density scenarios were created which ranged from 1 sample per 63,614 km2 to 1 sample per 634,350 km2, representing both low and high sampling density situations. The accuracy assessment was based on five robust prediction performance indices including mean error, mean absolute error, mean square error, root mean square error and Pearson correlation R, obtained from independent validation /cross-validation operation. The results show that generally, prediction accuracy was positively related to sampling density and sampling density accounted for 85% – 87% of interpolation accuracy as indicated in the RMSE and MAE for both EBK and EBKRP techniques. However, even though sampling density increased linearly, the rate of change in accuracy from one sampling density scenario to the next was not constant nor linear. A rapid increase (jump) in accuracy was noted when transiting from 40–60% sampling density scenario, but the rate remained fairly stable before and after 40% and 60%, respectively. For equivalent sampling density set-ups, EBKRP consistently performed better than EBK in all the accuracy metrics and EBKRP is generally considered to be about 40% better than EBK. Generally, the two interpolation techniques produced very low prediction bias at all the sampling density scenarios investigated. Our study suggests that potential effect of low sampling density and non-stationarity of sample data can be significantly reduced and, depending on the desired level of accuracy, EBK and EBKRP could produce reasonably accurate prediction surfaces even in a widely varying sampling densities settings. This is especially true for continuous and slowly varying phenomena such as temperature and similar variables.
