Failure analysis of weld cracking of gas gathering pipeline in dewatering station
Authors: Chen Yong , Xie Yi , Wang Wenjing , Li Jichuan 
Published: October 2022

AbstractThere are a lot of welded joints in the shale gas collection pipeline, so the failure risk of the shale gas production line is very high. A leak has occurred in the gas collection pipeline of a dewatering station, and in order to find out the causes of failure and provide technical support for safe shale gas transmission, macroscopic analysis, non-destructive testing (X-ray flaw detection), mechanical properties, and metallurgical analysis were performed on the failed pipe section, and CFD method was used to further analyze the failure mechanism of the ring weld pipe. The macroscopic analysis yielded the weld height is significantly greater than the standard minimum requirement. Non-destructive testing showed a large number of cracks with varying degrees of extension along the weld circumference on the inner surface of the weld. The chemical composition and mechanical properties of the pipe and the weld met the requirements. The microstructure of the base metal met the standard. There are no inclusions, holes, unfused areas, or other welding defects in the weld zone. The cracks originate from the weld fusion zone, and there are a large number of intergranular microcracks. CFD simulation results show that although the stress concentration caused by the height of the weld does not directly lead to weld cracking, under the influence of the stress concentration, cracks tend to sprout at the coarse grain organization of the fusion zone on the inner surface of the weld and can easily propagate throughout the weld and pipe wall thickness, leading to crack damage. Several suggestions to prevent such a failure were proposed to avoid the occurrence of similar accidents.

Abstract
Objective
The aim of this study was to compare the short- and long-term outcomes of laparoscopic surgery (LS) and open surgery (OP) for perihilar cholangiocarcinoma (PHC) using a large real-world dataset in China.

Methods
Data of patients with PHC who underwent LS and OP from January 2013 to October 2018, across 10 centers in China, were extracted from medical records. A comparative analysis was performed before and after propensity score matching (PSM) in the LS and OP groups and within the study subgroups. The Cox proportional hazards mixed-effects model was applied to estimate the risk factors for mortality, with center and year of operation as random effects.

Results
A total of 467 patients with PHC were included, of whom 161 underwent LS and 306 underwent OP. Postoperative morbidity, such as hemorrhage, biliary fistula, abdominal abscess, and hepatic insufficiency, was similar between the LS and OP groups. The median overall survival (OS) was longer in the LS group than in the OP group (NA vs. 22 months; hazard ratio [HR] 1.19, 95% confidence interval [CI] 1.02–1.39, p = 0.024). Among the matched datasets, OS was comparable between the LS and OP groups (NA vs. 35 months; HR 0.99, 95% CI 0.77–1.26, p = 0.915). The mixed-effect model identified that the surgical method was not associated with long-term outcomes and that LS and OP provided similar oncological outcomes.

Conclusions
Considering the comparable long-term prognosis and short-term outcomes of LS and OP, LS could be a technically feasible surgical method for PHC patients with all Bismuth–Corlett types of PHC.
Anchoring on Historical Round Number Reference Points: Evidence from Durable Goods Resale Prices
Authors: Wiltermuth Scott S. , Gubler Timothy , Pierce Lamar 
Published: October 2022

This paper examines how people price the resale of durable goods in systematically biased ways. We show across four studies that the anchoring effect of durable goods’ prior sales prices on subsequent valuations is discontinuous at psychologically salient round number reference points (e.g., $10,000 increments) because these numbers create qualitative differences in how people perceive values below them versus values at/above them. Resellers set disproportionately larger subsequent prices when previous prices move from just below round number thresholds (e.g., $349,000) to those at or just above these thresholds (e.g., $351,000). The findings show that buyers who pay a price just below a round number, therefore, may sacrifice money because they receive disproportionately less when reselling the good. Market forces only partially attenuate this pricing bias, but valuator experience seems to play a moderating role. Archival data show that home buyers who previously paid just under a $10,000 reference point subsequently listed their homes for about 1.8% (over $3,700) less on average than did buyers selling comparable homes who previously paid at or above a round number threshold. This drop is observable controlling for home characteristics and the general relationship between previous and current prices. Three experimental studies looking at housing and used car markets replicate these findings, highlight the mechanism, and increase confidence in causality. Market mechanisms and the negotiation process attenuate discontinuities by about 30%, but lower initial listing prices persist to final sales prices. We find additional weak evidence suggesting that valuator experience may attenuate intergenerational pricing bias.

The One vs. The Many
Authors: Everhart D. T. 
Published: October 2022

This paper looks at a recent exchange concerning the human nature of Christ and the Christological anthropology of Thomas F. Torrance. In this exchange, Oliver Crisp and Christopher Woznicki offer competing readings of Torrance’s Christological anthropology. Crisp argues for a concretist understanding of Christ’s human nature while Woznicki offers an abstractist metaphysic. This paper will look at this exchange in conversation with Torrance’s work and recent work in group ontology, offering a third way forward between the impasse of Crisp’s concretism and Woznicki’s abstractism which I call communal participation and argue is more in line with Torrance’s own understanding.

Dashboards for Decision Making in Higher Education
Authors: Tang Yoke Wah , Toh Suiying , Leow Alex Shuangjie 
Published: October 2022

Dashboards are used as a graphical user interface that provides at-a-glance views into key measures and trends to assist decision makers in the Singapore University of Social Sciences (SUSS) to enhance learning support for students.
A student’s first contact with SUSS often starts at the point of application (i.e., applying for places in the University). Hence, the process of application, selection and offer has been identified as the business problem in this project. An effective dashboard will empower users to make more informed decisions with a visibility to data and ease in generating insights, ultimately streamlining the selection and offer process. The users in this project are the stakeholders who deploy the dashboard in the process of and decision making related to selection and offer.
Quality of information on the dashboard is highly dependent on the state of data, including their completeness and accuracy. Quality of a dashboard can be measured by how much impact it can make, which is directly related to actions taken by users with information extracted from the dashboard. With the right knowledge and skills in developing an effective dashboard, business objectives can be met and user requirements can be catered for. If every decision maker is able to customise his/her own dashboards that meet business objectives and user requirements, the University will be empowered at a functional level, with various departments supporting students through their respective roles and functions. Challenges in data and people issues will be discussed in this paper alongside the future directions in overcoming these issues.
Strategic competence, task complexity, and foreign language learners’ speaking performance: a hierarchical linear modelling approach
Authors: Zhang Weiwei , Zhang Lawrence Jun , Wilson Aaron J. 
Published: October 2022

Abstract
Understanding the intricate relationships among strategic competence, tasks and performance is an issue of perennial interest in the assessment of foreign/second languages especially in integrated speaking assessment, a field that is under-researched. Against this background, we investigated such complex relationships in the context of integrated speaking assessment of English as foreign language (EFL) learners, hoping to provide additional empirical evidence to address the problem. In the investigation, strategic competence was defined as metacognitive strategy use and was measured via an inventory administered on 120 Chinese university EFL students; task characteristics were conceptualised as task complexity and were measured on a self-rating scale by the students and five EFL teachers; and the students’ speaking performance was indicated by their scores on four integrated speaking assessment tasks. Data analysis through a hierarchy linear modelling approach led to two primary findings: Monitoring, one form of strategic competence, moderated the effect of task complexity on performance; strategic competence had no substantial effects on performance which had an inverse relationship with task complexity. These findings will add validity evidence for the foreign language speaking assessment literature and provide implications for speaking instruction and test development.

Abstract
Inventory is the core link of enterprise operation and an essential resource for enterprises to occupy the market. Therefore, optimizing the control and management of inventory is a necessary measure for enterprises to maintain their core competitiveness. However, at present, the optimization of the enterprise’s inventory is basically still at the single inventory level, which seriously shortens the life cycle of the enterprise’s products and reduces the speed of the enterprise’s capital flow. Digital supply chain is the digitization of traditional supply chain services, which can change the traditional thinking of inventory control and management, break down the barriers between enterprises and modern logistics, and build a complete management system for enterprises. Smart logistics is a product of the new era, and it is also a product of the development of the digital supply chain. To this end, this paper proposes an inventory optimization algorithm based on digital supply chain and smart logistics. The algorithm is optimized on the basis of the original inventory optimization scheme, so that the improved algorithm can be more suitable for actual inventory management needs. The experimental results of this paper show that the improved new inventory optimization algorithm improves the comprehensive benefit by 39.1% on the original basis, which can effectively reduce the error in the actual use process.

Published: October 2022

Abstract

Objectives
To evaluate the risk and timing of spontaneous preterm birth (PTB) in asymptomatic twin pregnancies with a short cervical length (CL≤25 mm) at 23–28 weeks of gestation.

Methods
Multicenter retrospective cohort study of asymptomatic twin pregnancies with a short CL between 23 and 28 weeks’ gestation within a university health system from 1/2012 to 12/2019. Cases were divided into 4 groups based on CL measurement (≤10 mm, 11–15 mm, 16–20 mm, and 21–25 mm). The primary outcome was time interval from presentation to delivery. Secondary outcomes included delivery within one and two weeks of presentation, and delivery prior to 32, 34, and 37 weeks, respectively.

Results
104 patients were included. The time interval from presentation to delivery was significantly different among the four groups (p<0.001), with the CL≤10 mm group having the shortest time interval to delivery. Regardless of the CL measurement, spontaneous PTB within one and two weeks was extremely uncommon and occurred in only one patient within the study cohort (1/104, 1.0%). The risk of spontaneous PTB was highest in the shortest CL group (CL ≤ 10 mm; 53.8% PTB<32 weeks, 61.5% PTB<34 weeks, 92.3% PTB<37 weeks).

Conclusions
Asymptomatic twin pregnancies with a CL ≤ 10 mm had the shortest time interval to delivery and thus represent a specifically high risk group for sPTB. Although all patients were at high risk of sPTB, only one delivered within 1 or 2 weeks of presentation.

Abstract
Holograms hidden inside transparent materials are important for information encryption storage because of their advantages of secrecy, and could completely avoid information loss caused by surface wear. Inside the transparent material, the modified filaments array was need for hologram fabrication to change the optical phase or amplitude of incident laser, which is sensitive to the change of refractive index. Then the uniformity of modified filaments inside transparent materials is highly required. In this study, by tuning the interval time of the double-pulse processing, holograms with improved imaging quality were fabricated by double-pulse femtosecond laser and the effect and mechanism of self-trapped excitons (STEs) on the ablation have been systematically studied. The imaging quality of the hologram fabricated with double-pulse laser was superior to that of the one fabricated with the single-pulse laser and 350 fs was verified to be the best time interval for double-pulse processing. The evolution of the electrons dynamics was investigated by using the pump-probe technology. With the double-pulse time interval increasing, the residual electrons, excitons, STEs, and defects caused by the first sub-pulse would become dominated sequentially. The results demonstrated the controllability of STEs and quality improvement of final structures by double-pulse femtosecond laser processing.

Published: October 2022

Abstract
Quantitative molecular detection based on surface-enhanced Raman spectroscopy (SERS) is still a great challenge because of the highly nonuniform distribution of the SERS hot spots and the nondeterministic spatial and spectral overlap of the analyte with the hot spot. Here, we report a nanoparticle-on-mirror plasmonic sensor excited by surface plasmon polaritons for quantitative SERS detection of alpha fetoprotein in serum with ultrahigh sensitivity. The uniform gaps between the nanoparticles and gold film and the alignment of the gap modes relative to the excitation electric field endow this substrate with a uniform and strong SERS enhancement. The limit of detection reaches 1.45 fM, 697 times higher than that under normal excitation and 7800 times higher than a commercial enzyme-linked immunosorbent assay kit. This approach offers a potential solution to overcome the bottleneck in the field of SERS-based biosensing.

Published: October 2022

Abstract
Photodynamic therapy (PDT) for hypoxic tumors has attracted wide attention owing to its noninvasiveness, easy maneuverability, and instantaneity. However, hypoxia in tumors and penetration depth of conventional ultraviolet light has greatly weakened its performance. To solve these problems, under NIR-II light irradiation, squaric acid nanoparticles (SQ NPs) with superior reactive oxygen, especially, hydroxyl radicals (•OH) production performance were first utilized for hypoxic tumor therapy. SQ NPs with intense light capture capability, intense NIR emission, and excellent photobleaching resistance show continuous •OH generation capabilities under NIR-II laser excitation. Through the superior PDT performance, the growth of hypoxic tumors was effectively inhibited, and the survival rate of mice was improved. This work highlights the application of NIR-II photoexcitation in deep tissue type I photodynamic therapy of hypoxic tumors, which will facilitate the development of hypoxic tumor PDT in deep depth.
Jones-matrix imaging based on two-photon interference
Authors: Yung Tsz Kit , Liang Hong , Xi Jiawei , Tam Wing Yim , Li Jensen 
Published: October 2022

Abstract
Two-photon interference is an important effect that is tightly related to the quantum nature of light. Recently, it has been shown that the photon bunching from the Hong–Ou–Mandel (HOM) effect can be used for quantum imaging in which sample properties (reflection/transmission amplitude, phase delay, or polarization) can be characterized at the pixel-by-pixel level. In this work, we perform Jones matrix imaging for an unknown object based on two-photon interference. By using a reference metasurface with panels of known polarization responses in pairwise coincidence measurements, the object’s polarization responses at each pixel can be retrieved from the dependence of the coincidence visibility as a function of the reference polarization. The post-selection of coincidence images with specific reference polarization in our approach eliminates the need in switching the incident polarization and thus parallelized optical measurements for Jones matrix characterization. The parallelization in preparing input states, prevalent in any quantum algorithms, is an advantage of adopting two-photon interference in Jones matrix imaging. We believe our work points to the usage of metasurfaces in biological and medical imaging in the quantum optical regime.

Authors: Rathod Nilesh , Wankhade Sunil 
Published: October 2022

Abstract
In order to classify data and improve extreme learning machine (ELM), this study explains how a hybrid optimization-driven ELM technique was devised. Input data are pre-processed in order to compute missing values and convert data to numerical values using the exponential kernel transform. The Jaro–Winkler distance is used to identify the relevant features. The feed-forward neural network classifier is used to categorize the data, and it is trained using a hybrid optimization technique called the modified enhanced Invasive Weed, a meta heuristic algorithm, and Cuckoo Search, a non-linear optimization algorithm ELM. The enhanced Invasive Weed optimization (IWO) algorithm and the enhanced Cuckoo Search (CS) algorithm are combined to create the modified CSIWO. The experimental findings presented in this work demonstrate the viability and efficacy of the created ELM method based on CSIWO, with good experimental result as compared to other ELM techniques.
Communication networks used by smallholder livestock farmers during disease outbreaks: Case study in the Free State, South Africa
Authors: Nwafor Christopher Ugochukwu , Nwafor Ifeoma Chinyelu 
Published: October 2022

AbstractSmallholder livestock farmers routinely use existing communication networks as their information sources. This study explored these information sources, the frequency of contacts, and perceived usefulness of livestock health-related information received from these sources. Respondents were randomly selected from two farming districts in the Free State province. Using a mix of descriptive and correlation analyses, it categorized respondents according to their total information scores (TISs) and explored the relationship between their scores and socioeconomic characteristics. Findings show that 65% of farmers scored a high reliance on fellow farmers and extension officials. Mass media sources such as radio and television scored low on perceived usefulness. The correlation coefficients for age (−0.228), farming experience (0.183), extension visits (0.002), and information contacts (0.214) were significant (p< 0.05). Level of education (0.256), herd size (0.067), and perceived usefulness of information contacts (0.252) were also significant (p< 0.01). Gender, household size, income, cooperative participation, and access to financial services were not correlated to the TISs of respondents. It was recommended that mass media sources in the area be supported by extension communication specialists to disseminate livestock health-related information.
Consumers, not Contributors? The Study of the Mesolithic and the Study of Hunter-Gatherers
Authors: Elliott Ben , Warren Graeme 
Published: October 2022

Abstract
This article examines the relationship between the archaeology of the Mesolithic and the broader archaeology and anthropology of hunter-gatherers. Bibliographic reviews of articles presented at past MESO conferences and recent high-ranking Mesolithic research publications are compared to content reviews of contributions towards previous Conference on Hunting and Gathering Societies conferences. The results of these are presented as evidence to suggest that, whilst Mesolithic archaeologists consume the results of the broader field of hunter-gatherer research, we do not contribute to this field as much as might be expected. We argue that this lack of engagement impoverishes both Mesolithic archaeology and hunter-gatherer studies and that closer collaboration between these fields would open up new avenues for interdisciplinary research with the capacity to address the challenges of hunter-gatherer societies living around the world today.
Cause analysis of the fluorescent displays on the guide vane platform
Authors: Zhang H. Y. , Lv C. , Qu S. , Dong C. , Wang X. , Zhang Z. 
Published: October 2022

Abstract
After surface grinding, linear and dotlike fluorescent displays were found on the blade platform of a gas turbine guide vane. Through detailed inspections of macro- and micro morphologies and the crack fracture, the fluorescent displays are fine cracks in nature, and the difference in morphology is related to the distribution of the fine cracks. The fine cracks should be shrinkage cracks in castings. The grinding force caused internal cracks to appear on the grinding surface.
