This article investigates Chinese urban youth’s mediated ‘slice of life’ and playful encounters as part of their identity construction and performance work on Bilibili, one of China’s most influential video-sharing social media sites mediating anime, comics, games and novels. Using a mix-method approach of digital ethnography, participant observation, interviews and data visualisation, this article examines fans’ hermeneutic practices through anime, comic, game and novel prosumption, exemplified by danmaku: ‘bullet screen’, barrage-like comments overlaid on videos. This article argues that Bilibili works as an ‘identity college’ for fans to perform various roles and explore their hybrid identities in a social-hermeneutic engagement process. In particular, the function of anonymous danmaku comments will be closely analysed as it offers a quasi-real-time engagement experience for fans and helps shape fans’ social self. Following a symbolic interactionist tradition, Mead’s ‘generalised other’ and Goffman’s dramaturgical theory are contextualised in the Chinese socio-cultural milieu where fans’ identity performance is regarded as masquerade. Departing from the moral panic rhetoric that Generation Z is ‘amused to death’, becoming ‘infantile and animalised’, or even enslaved by their desires and capable only of ‘cold intimacies’, the findings of this explorative study present a more complex understanding of Chinese youth’s identity work through participatory social media use and networked fandom.

In the present work, a novel database of drug compounds and a rapid screening method based on ultra-high performance liquid chromatography coupled to high resolution orbitrap mass spectrometry were developed and applied in the screening and identification of targeted and nontargeted antihypertensive adulterants in dietary supplements and herbal medicines. The established screening database includes retention time, exact mass, fragments, isotopic pattern, and MS2 spectra library of the target compounds and thus provides automated search and identification of the targets with a single injection. The nontargeted compounds in the samples are identified through the full MS scan and MS2 data by using the Chemspider database and the data analysis in XCalibur, MassFrontier and TraceFinder software. In addition, this method possesses excellent quantitative capacity. The novel approach was applied to 65 batches of samples that are claimed as "all-natural" products having the antihypertensive function, among which nine batches were found to be positive. Multiple targeted and nontargeted antihypertensive adulterants were detected at levels ranging from 2.8 to 27.9 mg/g. The novel database and screening method demonstrated herein will be promising and powerful tools for rapid screening of antihypertensive adulterants in dietary supplements and herbal medicines.

Point-of-sale nutrition information has been adopted by numerous grocery stores to respond to the demand for easy-to-understand nutrition labeling by consumers. Although there is conflicting evidence regarding the effectiveness of providing nutrition information, previous research indicates simplified shelf nutrition labels may lead to healthier choices. However, these studies have not examined how different consumer segments respond to these labels, nor the differential impacts across foods. Using household purchase data from a store that voluntarily adopted the (now defunct) NuVal shelf nutrition labels (a 1-100 numeric score derived from a nutrition-profiling algorithm), we assess NuVal impacts across different consumers and foods. NuVal scores potentially influence not only purchase quantity but also likelihood of buying. Thus, the effect of NuVal was measured by estimating a two-part model and predicting consumers' unconditional purchase responses. We found evidence of heterogeneous impacts of NuVal across consumers and foods. High-income households and households with children shifted their yogurt and frozen dinner purchases to more healthful items. In contrast, households with children and households headed by heads with college education slightly shifted their canned soup purchases to less healthful options. Our findings suggest that specific foods and consumer segments are influenced by simplified shelf nutrition information and further research is necessary to better understand its effect on consumer dietary quality.

Objectives: To investigate the predictive factors for successful recanalization based on digital subtraction angiography and three-dimensional T1W sampling perfection with application-optimized contrasts using different flip angle evolutions (3D T1-SPACE) high-resolution magnetic resonance imaging (MRI) signal features.Methods: Consecutive internal carotid artery occlusion cases with ipsilateral ischemic stroke refractory to therapy who visited our institution between February 2017 and August 2020 were retrospectively analyzed. Epidemiology, symptomatology, imaging morphology on angiography and MRI, peri-procedural complications, technical success rate, and follow-up results were summarized. Factors related to technical success were analyzed using univariate and multivariate analyses.Results: In total, 75 cases (53 men, mean age 57.51 ± 9.71 years) were included. The total successful recanalization rate was 72.00% (54/75), with a complication rate of 13.33% (9/75). Through multivariate analysis, first ischemic stroke in Conclusion: Besides traditional features such as short ischemic event time, tapered stump, and distal ICA reconstitution by the ophthalmic artery, our study demonstrates that luminal and mural changes determined by 3D SPACE high-resolution MRI could also predict successful endovascular recanalization. Endovascular recanalization for non-acute internal carotid artery occlusion is feasible, but prudent case selection is mandatory considering the high periprocedural complication rate.

Summary shelf nutrition labels are one of a handful of practical strategies that hold the promise of improving nutrition and public health. We use a difference‐in‐differences approach to estimate the effect of the NuVal shelf label—an interpretive numeric score, now defunct, that rated the overall nutrition of foods from one (least healthful) to 100 (most healthful)—on consumer demand for yogurt. The results indicate that NuVal labels affected product sales through an information provision effect that increases with the value of the nutrition score on the product and a publicity (i.e., salience) effect that is unrelated to the level of the score. A one‐point increase in NuVal score on a yogurt product is estimated to increase demand by 0.23%.

Weft insertion based on electromagnetic launch technology is a novel and very promising approach for super broad-width (6–12 m) (SBW) looms. There are considerable challenges involved in designing such a system, including analyzing the electromagnetic field while incorporating the effect of a clip weft device, and accurately calculating the electromagnetic and motion parameters of the weft insertion mechanism. In this study, an electromagnetic launch, non-striking weft insertion method for an SBW loom is proposed. The electromagnetic field is analyzed with the finite element method and includes the effect of a clip weft device. Simulation of the motion, analysis of the maximum flight speed of the clip weft device and the work done by electromagnetic force are presented. We also describe an experimental model for electromagnetic launch weft insertion and calculate the electromagnetic force required for weft insertion, using analytical methods and numerical finite element methods. Comparison of the results with measured values shows that this electromagnetic launch weft insertion system has good flexibility. In addition, the weft insertion speed required for different width looms can be obtained by changing the current of the coil or the coil stage number of the launching system.

Objectives: Gait ataxia, incontinence, and cognitive impairment are three typical symptoms of normal pressure hydrocephalus (NPH), however, similarity to other diseases' presentation, the diagnosis of NPH can be frequently missed. NPH-related education program to healthcare professionals appears very well needed and could be a promising way to improve its early diagnosis and treatment, but the actual effect of training programs is unknown. Therefore, we launched the Yangpu Community Training Program and conducted a survey to investigate the knowledge and awareness of NPH among rehabilitation professionals and the effectiveness of our training program. Methods: We conducted a well designed survey among the participants before and after education of NPH and analyzed the responses of returned questionnaires. We compared the percent of respondents who never learned about NPH before and after training, and analyzed potential factors (year of graduation and professions) that might affect NPH education. We also examined the source of the acquired NPH knowledge and the percentage of respondents who demonstrated their increased knowledge of this disease. Results: Eighty-two and eighty-six questionnaires were returned before and after training, respectively. Based on data from the returned questionnaires, more than 80% of participants in the training program are rehabilitation therapists (physical, occupational and speech therapists), 15% are physicians, and 2% are nurses. Before participating in the training program, more than two fifths (41.46%) surveyed healthcare professionals had never learned about NPH, however this number dropped to 4.76% after training, Sixty percent participants indicated that they learned about NPH from the provided training programs. Conclusion: Our results demonstrate that NPH knowledge is lacking among healthcare professionals and that training programs are effective in NPH education. We expect that increased knowledge of this disease would result in improvement on early detection of this condition and appropriate intervention implemented to reduce the patients, family and health care burden in the future.

Objective: The aim of this study is to describe the technique and to evaluate the outcome of single-incision laparoscopic (SILC) approach for linea alba hernia in children. Materials and Methods: A 2 cm vertical umbilical incision was made and stretched horizontally. A 5-mm trocar was inserted through middle port for the telescope. Another extra-long 5-mm 30° trocar was inserted through the lateral port, 5 mm beside the middle port. The extraperitoneal fat was removed, and the defect of linea alba was repaired after hernial sac was excised. The peritoneum was reconstructed with interrupted suture. Results: From May 2014 to May 2015, eight children with linea alba hernia underwent SILC. Pre-operative abdominal ultrasound showed the average diameter of hernia ring was 3.2 ± 0.7 cm. Mean operation time was 32.5 min (range = 30–45 min). Oral intake was resumed during anaesthesia recovery period. All could endure pain and discharge on the post-operative 12 h. There was no post-operative wound infection. The follow-up period was 1–12 months, no recurrence and other complications occurred. Conclusions: SILC approach for linea alba hernia is a safe and effective, minimally invasive new technology. The linea alba hernia could be repaired with a cosmetic outcome.

Elbow cable terminal is widely used in ring main unit and cable branch box and is prone to causing fault. In this paper, experiment and disassembling analysis were made on a fault elbow cable terminal, which occurred faults repeatedly. It was investigated that the key processes of the fault elbow cable terminal were not well-controlled so that led to partial discharge. Finite element method (FEM) was used to calculate the electric field distribution of the elbow cable terminal and the result confirms that the key process is the main reason for the repeated faults. Finally, corresponding suggestions were proposed combined with practical operation and maintenance experience.

Aiming at the problem of inaccurate classification of big data information in traditional English teaching ability evaluation algorithms, an English teaching ability evaluation algorithm based on big data fuzzy K-means clustering and information fusion is proposed. Firstly, the author uses the idea of K-means clustering to analyze the collected original error data, such as teacher level, teaching facility investment, and policy relevance level, removes the data that the algorithm considers unreliable, uses the remaining valid data to calculate the weighting factor of the modified fuzzy logic algorithm, and evaluates the weighted average with the node measurement data and gets the final fusion value. Secondly, the author integrates the big data information fusion and K-means clustering algorithm, realizes the clustering and integration of the index parameters of English teaching ability, compiles the corresponding English teaching resource allocation plan, and realizes the evaluation of English teaching ability. Finally, the results show that using this method to evaluate English teaching ability has better information fusion analysis ability, which improves the accuracy of teaching ability evaluation and the efficiency of teaching resources application.

Distributed compressive video sensing (DCVS) is an effective method for small reconnaissance Unmanned Aerial Vehicle(UAV) to obtain high-quality videos on the battlefield. However, the existing reconstruction algorithms based on deep learning fail to make full use of the temporal correlation of videos, resulting in low reconstruction quality. In this paper, a measurement information compensation network called MCINet is used to compensate for the information in non-key frame measurements with the help of key frame measurements before initial recovery. At joint reconstruction stage, a neural network with autoencoder mix with recurrent neural network (RNN) structure called ECLDNet which makes full use of high-quality key frames is adopted, the encoder extracts temporal-spatial features from key and non-key frames, the RNN uses features of key frame to compensate for missing details in non-key frame features, the decoder reconstructs images in a symmetrical way with encoder. Experimental results indicate that our model can get an additional performance gain of more than 1.5 dB peak signal-noise ratio (PSNR) without any changes at the encoding end. The reconstruction runtime of our model increases slightly, but is still much less than iterative reconstruction algorithms due to the non-iterative nature of deep learning.

Firstly, the improved canny algorithm is used to extract the edge of the collected image of the shockproof hammer bolt, then the improved Hough transform is used to accurately locate the frame and center of the fastening bolt of the shockproof hammer, so as to complete the operation task of the anti-vibration hammer resetting robot. The experimental results show that the method proposed in this paper

This paper presents a combined strategy of the attitude control and vibration suppression for spacecraft with flexible appendages, in the presence of inertia parameter uncertainties and external disturbances. An adaptive robust output feedback controller is designed to achieve precise attitude control under parametric uncertainties and disturbances, and a LQR controller is proposed to suppress residual vibration. The effectiveness of the proposed method is verified by theorem proof and simulation results.

The Supplemental Nutrition Assistance Program (SNAP) provides millions of low-income Americans food benefits and other forms of nutrition assistance. Evidence indicates that SNAP reduces food insecurity. However, there is a concern that the food benefit may increase the demand for less healthy foods more than healthier foods, thereby reducing the overall nutritional quality of the participant’s food basket. This paper aims to examine the association of SNAP participation with the nutritional quality of food-at-home purchases of low-income households and to investigate the potential heterogeneity among consumers with different levels of nutrition attitude. This analysis used food purchase data from the USDA National Household Food Acquisition and Purchase Survey (FoodAPS). Our study sample included 2,218 low-income households, of which 1,184 are SNAP participants, and 1,034 are income-eligible nonparticipants. Multivariate regressions were performed to explore the SNAP-nutritional quality association. A household’s nutrition attitude was measured using its response to a question on whether the household searched for nutrition information online in the last 2 months. Households that affirmed they had an online nutrition search were treated as nutrition-oriented households (21.2% of the low-income sample), and households that did not were considered less nutrition-oriented households (78.8%). For robustness, we also created an alternative nutrition attitude measure based on reported use of the nutrition facts label. We found that among less nutrition-oriented households, SNAP participants had a statistically significant 0.097 points (p = 0.018) lower Guiding Stars rating than low-income nonparticipants. However, there was no significant SNAP-nutritional quality association among nutrition-oriented households. In conclusion, SNAP participation was associated with lower nutritional quality of food purchases among less nutrition-oriented households, but not among nutrition-oriented households. The results suggest that the intended nutritional benefits of restrictions on purchases of healthy foods may not reach the subgroup of nutrition-oriented SNAP participants.

Numerous studies have used store and household scanner data to investigate food policy issues. Some studies have focused on assessing the statistical properties of scanner data to provide a better understanding of the data. Topics of focus related to food policy include food pricing, food access, food assistance, market competition, health and nutrition claims, nutritional content, diet quality, and food safety. This chapter provides an overview of novel and interesting ways scanner data have been used to address food policy issues in the literature.

The One Belt One Road Initiative has promoted the fast development of Silk Road Tourism in so many ways. Contrary to the fast development of Silk Road Tourism, the legislation with regard to tourist-consumer protection is far more late-started. Tourists, as vulnerable consumers assumed to be the weaker contracting party, need a special protection in the realm of private international law when cross-border disputes arise. Nevertheless, despite the fact that Article 42 of the Chinese Conflicts Act provides a special consumer choice-of-law that favors the application of the law of consumer’s habitual residence, there is still no specific consumer jurisdiction rule in place. In addition, the notion of consumer or consumer contract enshrined in Article 42 of the Chinese Conflicts Act and Article 2 of the Consumer Protection Law remains unclear. In the absence of a clear definition of consumer (contract) and a specific consumer jurisdiction rule, the question is whether tourists in China can enjoy protective private international law rules in foreign-related travel disputes. By conducting an empirical analysis, this article aims to figure out the challenges faced by Chinese courts in judicial practice, and point out the aspects in the field of private international law that can be improved in the future to enhance tourist-consumer protection in international travel disputes.

BACKGROUND To explore the effects of metabolic syndrome (MS) on intestinal flora, inflammatory factors and infants of pregnant patients. METHODS A total of 62 pregnant patients with MS in our hospital from March 2016 to February 2017 were randomly selected as the case group, while 62 pregnant women without MS in our hospital during the same period were selected as the control group. The general clinical conditions, anthropometric parameters [height, weight, body mass index (BMI), waist circumference, hip circumference, waist-to-hip ratio (WHR), blood pressure and body fat content], laboratory test indexes [fasting blood glucose (FBG), fasting insulin (FINS), glycated hemoglobin A1c (HbA1c), homeostasis model assessment of insulin resistance (HOMA-IR), triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), serum C-reactive protein (CRP), interleukin-6 (IL-6) and intestinal flora], and infant outcomes were compared between the two groups. RESULTS In the case group, the mean gestational age was higher, and the proportions of subjects with a family history of diabetes, a family history of cardiovascular disease, and a history of cesarean delivery were greater than those in the control group (p < 0.05). In the case group, the BMI, waist circumference, WHR, body fat content, and mean systolic pressure were higher and larger than those in control group (p < 0.05). The case group had higher levels of FBG, HbA1c, FINS, HOMA-IR, TC, TG, HDL-C, LDL-C, serum CRP, and IL-6 than the control group (p < 0.05). In the case group, the levels of Enterobacteria and Saccharomycetes were higher (p < 0.05), while the levels of Bifidobacteria, Lactobacilli, and Bacteroidetes were lower than those in the control group (p < 0.05). The newborn birth weight was larger in the case group than that in the control group (p < 0.05), and the incidence rates of fetal macrosomia, hyperbilirubinemia, fetal distress, and meconium aspiration syndrome were higher in the case group than those in the control group (p < 0.05). CONCLUSIONS Pregnant women with MS have a higher risk of imbalance of intestinal flora, mild inflammatory response and glucolipid metabolism disorder.

Demand system estimates are useful tools to examine the effects of policy-induced changes in prices (i.e., taxes and subsidies), income, changes in food labels, and advertising on food purchasing patterns. This chapter illustrates techniques, opportunities, and challenges of estimating a food demand system using a combination of retail and household scanner data. It includes a general overview of estimating demand systems and an application of estimating a demand system for salty snacks using household purchase and retail sales information recorded in the IRI Academic Datasets.

Purpose The purpose of this paper is to develop a two-way coupling approach for investigating the aerodynamic stability of vehicles under the combined effect of crosswind and road adhesion. Design/methodology/approach The author develops a new two-way coupling approach, which couples large eddy simulation with multi-body dynamics (MBD), to investigate the crosswind stability on three different adhesion roads: ideal road, dry road and wet road. The comparison of the results obtained using the traditional one-way coupling approach and the new two-way coupling approach is also done to assess the necessity to use the proposed coupling technique on low adhesion roads, and the combined effect of crosswind and road adhesion on vehicle stability is analyzed. Findings The results suggest that the lower the road adhesion is, the larger deviation a vehicle generates, the more necessary to conduct the two-way coupling simulation. The combined effect of the crosswind and road adhesion can decrease a vehicle’s lateral motion on a high adhesion road after the disappearing of the crosswind. But on a low adhesion road, the vehicle tends to be unstable for its large head wind angle. The vehicle stability in crosswind on a low adhesion road needs more attention, and the investigation should consider the coupling of aerodynamics and vehicle dynamics and the combined effect of crosswind and road adhesion. Originality/value Developing a new two-way coupling approach which can capture the complex vehicle structures and the road adhesion with MBD model and the completed fluid filed structure with CFD model. The present study might be the first study considering the coupling of crosswind and low adhesion road. The proposed two-way coupling approach will be useful for researchers who study vehicle crosswind stability.

Objective Rex shunt (mesenteric-to-left portal vein bypass) is considered a more physiologically rational treatment for EHPVO than other portosystemic systemic shunts in children. However, about 13.6% of children with EHPVO do not have usable left portal veins and up to 28.1%. Rex operations in children are not successful. Hence, a Rex shunt in these children was impossible. This study reports a novel approach by portal-to-right portal vein bypass for treatment of children with failed Rex shunts. Material and methods Eight children (age 6.1 years, range 3.5–8.9 years) who underwent Rex shunts developed recurrent gastrointestinal bleeding and hypersplenism 13 months (11–30 months) postoperatively. After ultrasound confirmation of blocked shunt, they underwent exploration. Three patients were found to have right portal vein agenesis. Five patients (62.5%) were found to have the patent right portal vein, with the diameter of 3–6 mm. Four patients underwent bypass between the main portal vein in the hepatoduodenal ligament and the right portal vein by interposing an inferior mesenteric vein autograft, whereas the remaining patient underwent a bypass using ileal mesenteric vein autograft. Results The operations took 2.3 h (1.9–3.5 h). The estimated blood loss was 50 ml (30–80 ml), with no complication. The portal venous pressure dropped from 34.6 cmH2O (28–45 cmH2O) before the bypass to 19.6 cmH2O (14–24 cmH2O) after the bypass. The 5 patients were followed up for 10.2 months (4–17 months) and the post-operative ultrasound and CT angiography confirmed the patency of all the grafts and disappearance of the portal venous cavernova in all five patients. Conclusion The portal-to-right portal vein bypass technique is feasible and safe for treatment of children with EHPVO who have had failed Rex shunts. Our preliminary result indicates that this technique extends the success of Rex shunt from left portal vein to right portal vein and open a new indication of physiological shunt for some of the children who not only have had failed Rex shunts or but also are not suitable for the Rex shunts. Type of study Treatment study. Level of evidence Level IV.

Thomas Hardy has been one of the best-loved novelists to Chinese readers for nearly a century, which is an uncanny phenomenon in the circle of literature reception and circulation in China. It seems that Hardy has some magic power to have kept attracting Chinese literature lovers with his keen insight into nature, profound reflection on humanity and whole-hearted concern about human fate in the vast universe. Hardy’s works saturated with nostalgic sentiments for the traditional way of rural life exert unusual resonance in Chinese readers in terms of receptional aesthetic. There is no denial that Hardy is rather loved and admired by generation upon generation of Chinese literates, which can find expression in his exceeding popularity among readers from all trades and walks, from all levels, which ranges from middle school students to professors. In China, his prestige ranks only after Shakespeare among English persons of letters.

In this paper, we propose a hermetically sealed X-ray microchannel plate imager as a more effective and stable alternative to the traditional open-structured imager. With two microstrip photocathodes of 100 nm Au and 100 nm CsI , respectively, the proposed imager has a measured exposure time of 65 ps when applied with a 200 ps width gate pulse. The static response test shows that the image intensity of the CsI microstrip photocathode is 3.4 times that of the Au microstrip photocathode when illuminated by a non-monochromatic portable X-ray source with high energy photons. The sealed imager not only enhances the sensitivity and stability of the framing camera, but also has the potential to reduce crosstalks and artifacts, thus further improves the precision of measurement in practice.

This study aims to determine the safe and effective autologous blood drawing time for preoperative autologous blood donation (PABDs) by comparing the outcome of two different schedules of PABDs. A total of 144 patients who underwent elective surgery (radical resection of digestive tract tumor, lumbarspinesurgery and Intracranial tumor resection) were retrospectively reviewed. 88 patients had donated autologous blood 2 days before the operation (group 1); 56 patients had donated autologous blood more than 3 days before the operation (group 2). Hb and Hct before the operation and on postoperative days one and three, allogeneic blood transfusions, total bleeding, postoperative length of stay, and length of stay were measured and compared. Hb at postoperative day one was lower in group 2 than in group 1 (P 0.05)., The difference in the average number of postoperative hospitalization days between these two groups was not statistically significant (P > 0.05). The 2 days of PABD did not lead to any adverse recovery effect. It would be helpful to conduct preoperative autologous blood transfusions.

Currently, conventional enzyme immunoassays which use manual gold immunoassays and colloidal tests (GICTs) are used as screening tools to detect Treponema pallidum (syphilis), hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus type 1 (HIV-1), and HIV-2 in patients undergoing surgery. The present observational, cross-sectional study compared the sensitivity, specificity, and work flow characteristics of the conventional algorithm with manual GICTs with those of a newly proposed algorithm that uses the automated Bio-Flash technology as a screening tool in patients undergoing gastrointestinal (GI) endoscopy. A total of 956 patients were examined for the presence of serological markers of infection with HIV-1/2, HCV, HBV, and T. pallidum . The proposed algorithm with the Bio-Flash technology was superior for the detection of all markers (100.0% sensitivity and specificity for detection of anti-HIV and anti-HCV antibodies, HBV surface antigen [HBsAg], and T. pallidum ) compared with the conventional algorithm based on the manual method (80.0% sensitivity and 98.6% specificity for the detection of anti-HIV, 75.0% sensitivity for the detection of anti-HCV, 94.7% sensitivity for the detection of HBsAg, and 100% specificity for the detection of anti-HCV and HBsAg) in these patients. The automated Bio-Flash technology-based screening algorithm also reduced the operation time by 85.0% (205 min) per day, saving up to 24 h/week. In conclusion, the use of the newly proposed screening algorithm based on the automated Bio-Flash technology can provide an advantage over the use of conventional algorithms based on manual methods for screening for HIV, HBV, HCV, and syphilis before GI endoscopy.

Objective The cause of the chylous ascites in infants isn't completely clear. The purpose of this study is to discuss our experience of recognition of intestinal malrotation as a cause of congenital chylous ascites in infants. Methods Medical information of 10 infants with chylous ascites, who were admitted to the hospital between 2001 and 2014, was retrospective analyzed. Preoperatively, all patients underwent a period of conservative treatment. Results We found that nine of ten patients with intestinal malrotation, six of them underwent laparoscopic Ladd's procedure and three patients underwent open Ladd's procedure. The remaining one patient suffered from mesenteric lymph nodes rupture and laparoscopic resection was performed. The cylous ascites subsided in all patients after the surgery and no significant recurrence was encountered during follow-up time. Conclusions Our study demonstrates that congenital chylous ascites could be caused by intestinal malrotation, causing the obstruction of the lymphatic flow in the mesenteric lymphatic channels. Ladd's procedure maybe a safe and effective treatment for infantile intractable chylous ascites. Type of study Treatment study. Level of evidence Level IV.

The charging infrastructure, especially the planning and construction of fast charging stations, is extremely important in the process of electric vehicle (EV) marketization. This paper proposes a method which selects the constructing plan of charging stations with the lowest social costs from the candidate sets of constructing plans. First of all, the optimization model of siting and sizing of charging stations is created and the optimal number and location of the charging station (CS) in the unplanned areas and the optimal charging facility configuration can be obtained by solving the model. After that, the sequential construction strategy is proposed considered two development trends of the charging demand. According to the case results, the sequential construction strategy of charging stations can effectively reduce the growth rate of user's waiting time cost and total social cost and promote the charging facility utilization rate, which helps to avoid the loss of funds and waste of resources.

In an accelerator driven sub-critical system (ADS), an intense external neutron source provided by an accelerator coupled to a target is used to drive a sub-critical reactor. To ensure the stable operation of the reactor, it is of crucial importance to locate the beam spot on the target during the operation. In this paper, we have proposed a method for beam position measurement on the target’s beam entrance window. The proposed method is to measure the neutron flux outside the spallation target in the four directions of the east, south, west, and north. Since the neutron flux decreases with the distance between the detector and the beam center, the position of the beam center on the target’s entrance window can be extracted from the measured four neutron fluxes. The simulations based on FLUKA and OpenMC codes have indicated that the x and y positions of the beam center can be extracted from the measured four neutron fluxes. Since the four neutron detectors are fixed inside the reactor core, this method allows for continuous measurement of the beam position.

In this work, the cracks of HB4-49-14CdD swivel nut in aircraft were found and analyzed by macroscopic observation, morphology testing and metallographic examination. In order to figure out the cause of cracks, manufacturing and assembling process were investigated, and finite element method was used to simulate the tightening process. The results showed that overload tightening torque lead to the fracture and failure of swivel nut.

Objective In this randomized controlled study, we aimed to determine whether non-contact infrared thermometers (NCITs) are more time-efficient and create less patient distress than mercury axillary thermometers (MATs) and infrared tympanic thermometers (ITTs). Methods Forty-five rehabilitation inpatients were randomly assigned to one of three groups (NCIT, MAT, and ITT). Time required to measure body temperature with an NCIT, MAT, and ITT was recorded. We examined associations between time required to take patients’ temperature and measuring device used. Patient distress experienced during temperature measurement using the three thermometers was recorded. Results A significantly longer average time was required to measure temperatures using the MAT (mean 43.17, standard deviation [SD] 8.39) than the ITT (mean 13.74, SD 1.63) and NCIT (mean 12.13, SD 1.18). The thermometer used influenced the time required to measure body temperature (t = 33.99). There were significant differences among groups (NCIT vs. ITT, NCIT vs. MAT, and ITT vs. MAT) regarding patient distress among the different thermometers. Most distress arose owing to needing help from others, sleep disruption, and boredom. Conclusion The NCIT has clinically relevant advantages over the ITT and MAT in measuring body temperature among rehabilitation patients, including saving nurses’ time and avoiding unnecessary patient distress.
