Anorexia nervosa and inflammatory bowel diseases—Diagnostic and genetic associations

Abstract Background Anorexia nervosa (AN), a serious eating disorder, and inflammatory bowel diseases (IBD) share a number of key symptoms, for example, discomfort during eating and early satiety. Despite the symptom overlap, studies on comorbidity are limited and mostly conducted in relatively small samples. This study investigates the comorbidity of diagnosed AN with IBD, and the subtypes Crohn's disease and ulcerative colitis, in a population‐based sample and explores whether genetic factors could play a role in the overlap. Methods The study included 1,238,813 individuals born in Denmark 1981–2005 selected from the population register (5067 diagnosed with AN and 6947 diagnosed with any IBD), including a subsample of 23,236 individuals with genetic information (4271 with AN and 176 with any IBD). By combining hospital‐based diagnoses recorded in health registers until 2013 with polygenic scores (PGS) of AN and IBD, we investigated possible associations between diagnoses of each disorder, both within individuals and families, and between PGS of one disorder and diagnosis of the other disorder. Analyses were conducted using Cox regression and logistic regression. Results We found that a prior diagnosis of AN was associated with hazard ratios of 1.44 (1.05, 1.97) for any IBD, 1.60 (1.04, 2.46) for Crohn's disease, and 1.66 (1.15, 2.39) for ulcerative colitis, whereas IBD diagnoses were not significantly associated with later AN diagnosis. No significant within‐families associations were observed. We found no associations between AN and IBD using PGS. Conclusions AN was associated with later risk of IBD, Crohn's disease, and ulcerative colitis; however, the reverse was not observed. It is important for clinicians to be aware of this association to evaluate IBD as a differential diagnosis or an emergent condition in patients with AN.

Epidemic algorithms for reliable and efficient information dissemination in vehicular

Vehicular ad hoc networks (VANET), which are created by vehicles equipped with short- and medium-range wireless communication, have an array of important applications in intelligent transport systems. Many of these applications require reliable, bandwidth-efficient dissemination of traffic and road information via ad hoc network technology. This is a difficult task since inter-vehicular networks often lack continuous end-to-end connectivity and are characterised by large variations in node density. A new epidemic algorithm for information dissemination in highly dynamic and intermittently connected VANET is introduced. It is shown through realistic simulations in highway traffic that the proposed algorithm is capable of reliable and efficient information dissemination in VANET in the face of frequent network fragmentation and large density variations.
Covid-19 #Takeresponsibility: A Multimodal Discourse Analysis of Select NCDC’s Online Public Health Advertising Campaign

This article examines the Nigerian Center for Disease Control’s (henceforth, NCDC) Covid-19 #TakeResponsibility online public health advertising campaign. This is with a view to exploring how the representational, interactive and compositional resources are realized in these advertising visuals as well as their communicative functions. Forty purposively selected data samples, which were subjected to qualitative analysis, are examined from a multimodal discourse analytical approach. The analysis reveals that the narrative, transactive, action, offer, and the frontal resources, among others, are realized in the adverts. These resources interactively perform the directive, informative, reinforcing, preventive, cautionary and collective functions. Thus, the representational, interactive and compositional resources deployed in the NCDC’s Covid-19 #TakeResponsibility online visuals discursively cohere as multimodal public health campaign strategies geared towards sensitizing the Nigerian populace on the safety guidelines to adhere to in containing the spread of Covid-19 in Nigeria.
Assessment of Sandcrete Blocks Quality in Owerri, Imo State, Nigeria

This study assessed the production management practice being adopted in the manufacture of quality sandcrete blocks in selected sampled parts of Owerri municipal, Imo State, Nigeria. Myriads of literature identify sandcrete blocks as a significant material being used in the building & civil engineering practice and assert that its application as a walling material cannot be over emphasized. Sandcrete block manufacturers in Owerri, Imo State were used for the assessment of the quality of their products in line with the Nigeria Industrial Standard (NIS) specifications. The study adopted field sampling, experimentations and work study methods to determine the compressive strength and water absorption rate properties of the selected sampled sandcrete blocks. The results of the study reveals among others that the mean compressive strength values obtained were as low as 1.92N/mm2, and about 17% water absorption rate from sampled commercial blocks. The results obtained did not compare favorably with the NIS specified acceptable minimum standard values. The study therefore underpinned poor production quality control practice as well as lack of impact of regulatory bodies in Imo State as among factors that contributed to the negative results obtained.
Study on the Water Supply and the Requirements, Yield, and Water Use Efficiency of Maize in Heilongjiang Province Based on the AquaCrop Model

Agricultural irrigation depends heavily on freshwater resources. Under the context of increasingly severe water shortages, studying the relationship among crop water requirements (ETc), actual crop evapotranspiration (ETa), irrigation water requirements (Ir), yield, and water use efficiency (WUE) would be beneficial to improve the agricultural application of irrigation water. Based on the daily data of 26 meteorological stations in Heilongjiang Province from 1960 to 2015, this study used the calibrated AquaCrop model to calculate the ETc, ETa, Ir, and yield of maize (Zea mays L.) in different hydrological years (extremely dry years, dry years, normal years, and wet years) along with WUE to evaluate the mass of yield produced per unit mass of crop evapotranspiration (ET) under rainfed and irrigated scenarios. The results showed that ETc and ETa decreased first and then increased from the west to the east during the four types of hydrological years. Ir exhibited a decreasing trend from the west to the east. Compared with the irrigation scenario, the rainfed scenario’s average yield only decreased by 2.18, 0.55, 0.03, and 0.05 ton/ha, while the WUE increased by 0.32, 0.4, 0.33, and 0.21 kg/m3 in the extremely dry years, dry years, normal years, and wet years, respectively. The results indicated that in the normal and wet years, the WUE was high in the central regions, and irrigation did not significantly increase yield; further, we determined that irrigation should not be considered in these two hydrological years in Heilongjiang Province. In the extremely dry and dry years, irrigation was necessary because it increased the yield, even though the WUE decreased. This study provides a theoretical basis for studying the regional irrigation schedule in Heilongjiang Province.
Responses of Stock Price to the Public Announcement of Forms of Borrowing

This study investigates the question of whether an announcement of bank loan agreement increases the abnormal return. That is, the bank loan agreement conveys some positive information about the borrowing firm. The study used three different event windows (i.e.) two-day, three-day, and five-day windows to check the effect of the announcement for a period of 1995 to 2015. In order to measure the effect, the return has been calculated using the market model, then CARs have been calculated. The study found that CARs is statistically significant for all of the three-event windows. In the two-day window, it is found that abnormal return increases by 15 BPS within these two days, which is almost 19.315% on an annual basis. It is also evident in the study that the effect of the announcement is more on small size firms.
A Comprehensive Methodology for Assessing Human-Robot Team Performance for Use in Training and Simulation

New methodologies and quantitative measurements for evaluating human-robot team performance must be developed to achieve effective coordination between teams of humans and unmanned vehicles. The Mixed Initiative Team Performance Assessment System (MITPAS) provides such a comprehensive measurement methodology. MITPAS consists of a methodology, tools and procedures to measure the performance of mixed manned and unmanned teams in both training and real world operational environments. This paper describes MITPAS and the results of an initial experiment conducted to validate the measures and gain insight into the effect of robot competence on operator trust as well as on human-robot team performance.
Determining the endurance limit of AISI 4340 steels in terms of different statistical approaches

In engineering applications, fatigue phenomenon is a key issue and needs to be analyzed in the beginning of design phase in case of any component exposed to alternating loading on operation otherwise catastrophic fatigue failure may cause. Component can be designed with safe-life, fail-safe, and damage tolerant approach based on whether redundant load path and damage sensitive. Before starting analyzing the structure, material allowable data needs to be presented in a reliable way to predict fatigue life of components. SN curves with presented confidence levels are the robust approach to make a prediction on safe life of a structure in terms of fatigue. In this point, there are so many approaches to determine fatigue limit of materials and issue shall be handled by statistical manner. In literature, different staircase and curve fitting methods were presented to estimate endurance limit of materials and some reliability manuscript published. In this paper, fatigue limit of AISI 4340 steel will be investigated through most convinced staircase and curve fitting approaches and their reliability will be queried.
Performance Criteria for Residential Zero Energy Windows

This paper shows that the energy requirements for today's typical efficient window products (i.e. ENERGY STAR{trademark} products) are significant when compared to the needs of Zero Energy Homes (ZEHs). Through the use of whole house energy modeling, typical efficient products are evaluated in five US climates and compared against the requirements for ZEHs. Products which meet these needs are defined as a function of climate. In heating dominated climates, windows with U-factors of 0.10 Btu/hr-ft{sup 2}-F (0.57 W/m{sup 2}-K) will become energy neutral. In mixed heating/cooling climates a low U-factor is not as significant as the ability to modulate from high SHGCs (heating season) to low SHGCs (cooling season).
High-coupling-efficiency optical interconnection using a 90/spl deg/-bent fiber array connector in optical printed circuit boards

A high-coupling-efficiency optical interconnection has been demonstrated using a 90/spl deg/-bent fiber array connector to deflect beams between surface-emitting lasers or surface-receiving photodiodes and optical layers embedded in a board. A 90/spl deg/-bent fiber array is mounted in a tetragonal body with a millimeter scale size to make it suitable for passive packaging in the board. The bending radius of silica fibers in the connector was controlled to have 1.5 mm resulting in bending loss of about 0.5 dB. An optical link of 2.5-Gb/s signals with a total interconnection loss of -1.3 dB was demonstrated using the connectors and a fiber-embedded board.
Breeding Waterbird Populations Have Declined in South San Francisco Bay: An Assessment Over Two Decades

Availability of wetlands with low salinities during the breeding season can influence waterfowl reproductive success and population recruitment. Salinities as low as 2 ppt (3.6 mScm–1) can impair duckling growth and influence behavior, with mortality occurring above 9 ppt (14.8 mScm–1). We used satellite imagery to quantify the amount of available water, and sampled surface water salinity at Grizzly Island, in the brackish Suisun Marsh, at three time-periods during waterfowl breeding (April, May, July) over 4 years (2016–2019). More water was available and salinity was lower during wetter years (2017, 2019) than during drier years (2016, 2018), and the amount of water in wetlands decreased 73%–86% from April to July. Across all time-periods and years, the majority (64%–100%) of wetland habitat area had salinities above what has been shown to negatively affect ducklings (> 2 ppt), and up to 42% of wetland area had salinities associated with duckling mortality (> 9 ppt). During peak duckling production in May, 81%–95% of available water had salinity above 2 ppt, and 5%–21% was above 9 ppt. In May of the driest year (2016), only 0.5 km2 of low-salinity water (< 2 ppt) was available to ducklings in the study area, compared to 2.6 km2 in May of the wettest year (2017). Private duck clubs own the majority of wetland habitat at Grizzly Island and consistently had a greater percentage of land flooded during summer than did publicly owned wetlands, but private wetlands generally had higher salinities than public wetlands, likely because they draw from higher-salinity water sources. By July, few wetlands remained flooded, and most had salinities high enough to impair duckling growth and survival. Local waterfowl populations would benefit from management practices that provide fresher water during peak duckling production in May and retain more water through July.
Wind-Induced Pressures on Solar Panels Mounted on Residential Homes

AbstractThis paper presents wind load investigations on solar panel modules mounted on low-rise buildings with gable roofs that have two distinct slopes. Wind loads on the solar panels mounted on several zones of the roofs were systematically investigated in a boundary-layer wind tunnel for different wind directions. The results from the wind-tunnel investigation are compared with ASCE provisions for residential bare roofs. The comparison shows a good agreement with the ASCE standard provisions for the main force resisting system. Nevertheless, the cladding loads on individual modules may be lower or higher than those on the corresponding area of a bare roof (depending on their location and array configuration and the roof’s slope). Avoiding the roof critical zones (zones 3 and 2) is recommended to avoid high net minimum pressures acting on the solar panel modules. Solar panels mounted in zone 1 are locally subjected to higher suction at their outer edges. This is most likely attributed to the effect of a.

This research was conducted by researching the gap between the relationship between e-service quality and customer satisfaction and its effect on repurchase interest. The study was conducted to see whether all variables of electronic service quality (usage, website design, responsiveness, personalization / customization, and assurance) had an effect on the total service quality and customer satisfaction which could lead to repurchase. The analysis technique used is SEM (structural equation modeling) with the number of respondents as many as 197 Lazada customers in the city of Semarang. The results of the criteria for goodness of fit RMSEA = 0.066; NFI & NNFI = 0.96 & 0.94; IFI = 0.92; and RFI = 0.93. These results indicate that the model has a good fit and is feasible to use. Based on the research results, there are four hypotheses that have a positive and significant effect, namely, web design, responsiveness, customization, and customer satisfaction on repeat purchase intention. However, there were two objections that were rejected, namely the use of (ease of use) and assurance (assurance) of repeat purchase intentions. Keywords : e-service quality, customer satisfaction, repurchase intentions, Lazada.
Characteristics of Dynamic Positioning Operators' Situation Awareness and Decision Making during Critical Incidents in Maritime Operations

The maritime and offshore industries are increasingly becoming dependent on Dynamic Positioning (DP) systems for automated vessel station keeping. This study aimed to identify characteristics of DP Operators' Situation Awareness (SA) and decision-making during critical incidents. Critical incidents were defined as events that were unplanned, non-routine and where accidents could be avoided. SA was defined by Endsley's three levels model involve perception of cues in the environment (Level I SA), understanding the meaning of the cues (Level II SA) and projection of system state (Level III SA). Semi-structured interviews using the Critical Decision Method were conducted with 13 experienced DP operators. The onset of the critical incident in all 24 incidents was used as a center point for the creation of event trees. Results indicate that in 10 incidents the DPOs were not able to identify the base events (did not form Level I SA) but were able to realize the problem (understand the situation, e.g. form Level II SA), indicating that the establishment of high-level SA may not depend entirely on the establishment of low-level SA. This study contributes to an improved understanding of the formation of situation awareness and the recovery of critical incidents during demanding maritime operations.
PVDF promotes TiO2 dispersion to obtain composite films with high dielectric constant and low loss

A series of three-phase composite films with different filler contents were prepared by in-situ polymerization. The composite films comprise polyimide (PI), poly (vinylidene fluoride) (PVDF), and titanium dioxide (TiO2). Compared with PI/TiO2 composite films, the PI/TiO2-PVDF composite films not only get a significant increase in dielectric constant, but also own better mechanical properties. Our results show that with the loading of 50wt% PVDF particles, the dielectric constant of PI/TiO2-PVDF composite films increased from 6.5 to 18.14 at 1 MHz and room temperature, while the tensile strength of PI/TiO2-PVDF composite films increased from 45 to 72 MPa. In addition, the films maintain a low loss tangent of about 0.02. PI/PVDF composite films were also prepared. It was found that dielectric constant of PI/PVDF composite was significantly lower than that of PI/TiO2-PVDF composite films when the loading of PVDF is 50wt%.
Contact Kinematics in the Roller Screw Mechanism

This paper investigates the nature of the contact between the load transferring surfaces in the roller screw mechanism, i.e., between the screw and roller threads and between the nut and roller threads. The analysis is applied to both planetary roller screws and recirculating roller screws. Prior work has neglected to take a fundamental approach toward understanding the kinematics of the contact between these components and, as a consequence, detailed analyses of aspects such as contact mechanics, friction, lubrication, and wear are not correctly carried out. Accordingly, in this paper, the principle of conjugate surfaces is used to establish contact at the screw/roller and nut/roller interfaces. The in-plane angles to the contact points are derived and it is shown that for the screw/roller interface, the contact point cannot lie on the bodies' line of centers, as has been the assumption in previous papers. Then, based on the curved profile of the roller thread, the radii of contact on the roller, screw, and nut bodies are also derived. Knowledge of the contact point locations is necessary in order to understand the interaction forces between the key components of the roller screw mechanism. The principal radii of curvature at the contact points and the angle between the principal axes are also derived. Lastly, a brief example is developed showing how the developed theory may be used to design a roller screw for improved stiffness and decreased contact stresses.
Extensive mucosal sloughing of the small intestine and colon in a patient with severe COVID‐19

Abstract Patients with coronavirus disease 2019 (COVID‐19) primarily cause respiratory symptoms. However, gastrointestinal (GI) symptoms can also occur. The endoscopic characteristics of the GI tract in COVID‐19 patients remain unclear. We herein report a 62‐year‐old male with severe COVID‐19 who needed multidisciplinary treatment, including extracorporeal membrane oxygenation (ECMO). Despite the improvement in his respiratory status, GI bleeding developed. Capsule endoscopy and colonoscopy revealed extensive mucosal sloughing in the lower intestinal tract. Additionally, we performed a comprehensive analysis of the mRNA expression levels of various proinflammatory cytokines in the intestinal mucosal tissues. The results suggested a significant elevation of IL‐6, which could be involved in the pathophysiology of the GI involvement in COVID‐19. Further investigation with more clinical data, including endoscopic findings and molecular analyses, will contribute to a comprehensive understanding of COVID‐19‐associated GI injury.
