Specific Avenin Cross-Reactivity with G12 Antibody in a Wide Range of Current Oat Cultivars

Current clinical studies confirm that the consumption of oats for people suffering from celiac disease is safe. Some studies have confirmed different levels of immunoreactive gluten epitopes of oats in different cultivars, while others explain these differences due to contamination with gluten-rich species or as random cross-reactivity ELISA of homologous oat epitopes with anti-wheat gliadin antibodies. The aim of our two-year study was therefore to map cross-reactive oat epitopes in a set of 132 oat cultivars using a G12-based ELISA kit. The results were focused on the varietal and annual level of cross-reactivity (interference) of avenin epitopes with the G12 antibody on the identification of potential cultivars with significantly different interferences and assessing the degree of risk of possible false-contamination with external gluten. Although repeated evaluations confirmed high year-to-year variability (RSD ≥ 30%) in approximately 2/3 of the cultivars, the content of interfering avenin epitopes with G12 did not exceed the considered safe limit (20 mg·kg−1) for celiacs. At the same time, not only annual but, above all, significant cultivar dependences in the interference of avenins to the G12 antibody were demonstrated. Genetic dependence was further confirmed in connection with the proven avenin polymorphism as well as immunoblotting with the identification of interfering peptides with the G12 antibody in the 25 and 30 kDa regions. It was the occurrence of two bands around 30 kDa that predominantly occurred in oat cultivars with a relatively higher content of cross-reactive avenins (12–16 mg·kg−1). Due to the fact that the contents of interfering avenins ranged in several cultivars even over 16 mg·kg−1, the choice of a suitable oat cultivar may be crucial for gluten-free food producers, as it reduces the risk of a possible false-response of the commercial ELISA kits when checking the real-gluten contamination.
Energy harvesting and information processing in two-way multiplicative relay networks

An energy harvesting (EH) and information processing network based on two-way multiplicative relay is proposed. In the proposed scheme, two nodes communicate with each other via an energy constrained multiplicative relay node. The relay node uses power splitting-based relaying protocol for EH and information processing. The numerical results show that the proposed scheme outperforms the legacy amplify-and-forward EH relaying technique.
Bitstream-Quality-Estimation Model for Tile-Based VR Video Streaming Services

SUMMARY Tile-based virtual reality (VR) video consists of high- resolution tiles that are displayed in accordance with the users’ viewing directions and a low-resolution tile that is the entire VR video and displayed when users change their viewing directions. Whether users perceive quality degradationwhenwatchingtile-basedVRvideodependsonhigh-resolutiontilesize,thequalityofhigh-andlow-resolutiontiles,andnetworkcondition.Thedisplaytimeoflow-resolutiontile(hereafterdelay)aﬀectsusers’per-ceivedqualitybecauselongerdelaymakesuserswatchthelow-resolution tileslonger. Sincethesedegradationsoflow-resolutiontilesmarkedlyaﬀect users’ perceived quality, these points have to be considered in the quality-estimation model. Therefore, we propose a bitstream-quality-estimation model for tile-based VR video streaming services and investigate the eﬀect of bitstream parameters and delay on tile-based VR video quality. Subjec- tive experiments on several videos of diﬀerent qualities and a comparison between other video quality-estimation models were conducted. In this pa- per, we prove that the proposed model can improve the quality-estimation accuracy by using the high- and low-resolution tiles’ quantization parame- ters, resolution, framerate, and delay. Subjective experimental results show that the proposed model can estimate the quality of tile-based VR video more accurately than other video quality-estimation models.
Integrated Stratigraphy (Radiolarians, Calcareous Nannofossils, Carbon and Strontium Isotopes) of the Sinemurian–Pliensbachian Transition at Mt. Rettenstein, Northern Calcareous Alps, Austria

A 95 m thick succession of grey siliceous limestone and marl on Mount Rettenstein in the Northern Calcareous Alps allowed us to study well-preserved and diverse radiolarian assemblages across the Sinemur-ian – Pliensbachian boundary. The distribution of 31 most characteristic radiolarian species is presented. Am-monites of the Jamesoni Subzone, the topmost subzone of the Jamesoni Zone, have been previously found in the upper part of the section. The radiolarian data are complemented with calcareous nannofossil biostratigraphy, and carbon and strontium isotope analyses of bulk carbonate samples. A negative stable carbon isotope excursion (CIE) occurs in the middle part of the section and is correlated to the supraregional Sinemurian – Pliensbachian Boundary Event. Radiolarian assemblages below the negative CIE belong to the C anutus rockfishensis – Wrangellium thurstonense and Jacus ? sandspitensis radiolarian zones. Katroma clara and several other species belonging to the subsequent Canutus tipperi – Katroma clara Radiolarian Zone first occur at the beginning of the negative CIE. The first occurrence of the nannofossil Similiscutum cruciulus , which defines the base of the NJ4 Calcareous Nannofossil Zone, was recognized near the top of the negative CIE, 10 m above the inferred stage boundary. The strontium isotope ratio is due to diagenetic alteration of bulk micrite systematically shifted to higher values, but clearly decreases across the stage boundary. This decrease is compatible with the trend of the standard 87 Sr/ 86 Sr curve established in skeletal calcite. This is the first time radiolarian zones across the Sinemurian – Pliensbachian boundary in Europe can be tied to calcareous nannofossil zones and chemostratigraphy and also calibrated to chronostratigraphy. These results contribute to the stability of Lower Jurassic radiolarian zones and will allow the recognition of the Sinemur-ian – Pliensbachian boundary in deep-marine successions where ammonites are absent.
Incidence and Risk Factors for Venous Thromboembolism in Female Patients Undergoing Breast Surgery

Simple Summary Despite the known multiple correlations between venous thromboembolism (VTE) and breast cancer, only a limited number of studies have investigated the association between breast cancer and VTE during the long-term follow-up. Given the constantly increasing number of newly diagnosed breast cancers, the significance of focusing research on the correlation between breast cancer and VTE is becoming increasingly relevant. Furthermore, VTE has a high impact on a patient’s quality of life, with permanent consequences or mortality in the most severe cases. Thus, this study aims to assess the occurrence and timing of VTE during a long period of follow-up to analyze possible correlated factors and the overall survival. These results could impact the health care community, adding knowledge about VTE risk factors. These factors can be helpful as prognostic information and eventually target preventive treatment for VTE because the co-existence of invasive breast cancer VTE has a substantial impact on survival. Abstract Albeit it does not have the highest venous thromboembolism (VTE) incidence compared to other neoplasms, breast cancer contributes to many VTE events because it is the most diagnosed tumor in women. We aim to analyze the occurrence and timing of VTE during the follow-up of patients who underwent breast surgery, the possible correlated factors, and the overall survival. This retrospective study included all female patients diagnosed with mammary pathology and surgically treated in our clinic between January 2002 and January 2012. Of 5039 women who underwent breast surgery, 1056 were found to have no evidence of malignancy, whereas 3983 were diagnosed with breast cancer. VTE rate resulted significantly higher in patients with invasive breast cancer than in women with benign breast disease or carcinoma in situ. Invasive cancers other than lobular or ductal were associated with a higher VTE rate. In addition, chronic hypertension, high BMI, cancer type, and evidence of metastasis turned out to be the most significant risk factors for VTE in women who underwent breast surgery. Moreover, VTE occurrence significantly impacted survival in invasive breast cancer patients. Compared to women with benign mammary pathology, VTE prevalence in women with breast cancer is significantly higher. The knowledge about the risk factors of VTE could be helpful as prognostic information, but also to eventually target preventive treatment strategies for VTE, as far as the co-existence of invasive breast cancer and VTE has a significantly negative impact on survival.
Corporate Private Information and Credit Ratings: Evidence from Corporate Geographic Distance

ABSTRACT This paper uses the geographic distance between corporate locations and headquarters of credit rating agency as a proxy for corporate private information acknowledged by rating agency, to investigate the effect of corporate private information on its credit ratings. Our samples include the Chinese institutional and corporate bond’s credit ratings from 2008 to 2018. Results indicate the geographic distance is negatively associated with the corporate private information accessed by rating agency, leading to a higher information asymmetry, worse institutional and corporate bonds’ credit rating and lower quality of the rating information content. Results remain solid and significant after controlling for the implicit guarantee of the government, corporate public information, ownership structure and analysts’ skills. We find corporate private information generates more values for corporates whose information environments are more complex, reflected in more business segments and less covered analysts. We also find the open of high-speed railway in China facilitates rating agency’s access to corporate private information, thus reducing the impact of geographic distance, while the lockdown periods of Covid-19 pandemic in China suddenly increase the cost of collecting private information and thus aggravating the distance effect.
Criteria for the identification of ineffective open data portals: pretender open data portals

Open data are considered an essential resource for governments, businesses, and citizens. In that context, open data portals have potential for creating enormous economic growth. Open data portals should allow the reuse of open data, ensure the efficiency of data transmission, and enable professional initiatives based on data reuse. However, there are portals that are inefficient because they do not allow reuse of their data. The objective of this work is to define and identify open data portals that do not offer the possibility for professional reuse of their data. We refer to them as “pretender open data portals”. The following research questions are considered herein: What minimum criteria must an open data portal satisfy to enable professional reuse of open data? How can portals that do not meet these criteria be identified? And, what problems might these portals present, and how they might be solved? The results of an analysis of two samples of open data portals in Spain reveal that 63.8% and 56.1% of the portals analyzed in 2019 and 2021, respectively, can be considered pretender open data portals. The existence of pretender open data portals can have negative economic and social impacts, such as wasting public resources and projecting a negative image of the government’s open data policies. To find coordination mechanisms to develop open data portals that, through the professional re-use of their data can create economic and social value, is one important challenge. The analysis of best practices of open data portals can be also a way to go in deep in the understanding of open data reuse impact not only from a professional standpoint.
Prevalence of Adverse Childhood Experiences Among Frontline Homeless Services Workers in Texas

A personal history of trauma can be a risk factor for job-based secondary traumatic stress and burnout. Experts have pointed to the need to understand the prevalence of adverse childhood experiences (ACEs) among people on the frontlines of health and human services to ensure adequate supports. A small body of literature has examined the prevalence of ACEs among direct service providers, including child welfare workers and social workers. This study adds to that research by assessing the prevalence of ACEs in a sample of frontline homeless service workers. Findings suggest an ACE prevalence higher than the general population but similar to that found in other studies of direct service professionals. Implications for organizational support and trauma-informed supervision are discussed.
Children's physical activity and active travel: a cross-sectional study of activity spaces, sociodemographic and neighborhood associations

ABSTRACT Measures of individual mobility, such as activity space, have been previously used to help improve our understanding of individuals’ interactions with their everyday environments. However, such methods have rarely been adopted in studying children's physical activity and active travel behavior. In this study, we use a combination of participatory mapping and accelerometer data collected from children aged 8–13 years living in Tāmaki Makaurau/Auckland, Aotearoa/New Zealand, to describe children's travel behavior and explore associations of active travel, physical activity, and socio-demographic characteristics with environmental attributes. The results from this study reveal complex associations between these different layers. Density of cycling routes was consistently associated with higher levels of physical activity captured via moderate-to-vigorous physical activity (MVPA), prevalence of active travel, and total activity space exposure. Nevertheless, population density, greenspace, and land-use mix revealed varying associations across different activity behaviors including MVPA, number of steps, and prevalence of active travel. The results from this study not only reassert the complexity of person–environment relationships, but also highlight the potential impacts of measurement and analytical methods on the study results. The novel combination of participatory mapping and accelerometer data together with activity space analysis provided new analytical insights which we discuss in this paper. This study concludes by reporting its observations and envisioning future research directions.
Intracranial hemorrhage following drainage of chronic subdural effusion and hematoma: A case report and review of the literature

Abstract Acute intracranial hemorrhage (AIH) after drainage of chronic subdural hematoma is a rare but serious complication. An 86‐year‐old man with bilateral frontotemporal subdural effusion, hematoma, and cerebral hernia was admitted to our department and treated with bilateral burr hole surgery and closed‐system drainage under local anesthesia. After the operation, computed tomography (CT) showed AIH in the left temporal and occipital lobe, and then a series of head CT showed that the hematoma gradually increased day by day. This patient had a medical history of hypertension, diabetes, atrial fibrillation, and taking warfarin. He was treated conservatively, but had not recovered at discharge after 1 month. We reviewed the relevant literature and analyzed the operation opportunity, causes of cerebral hemorrhage, and preventive measures in similar patients. We suppose that the coagulation abnormality and rapid fluctuations of intracranial pressure were the main causes of development of AIH in our patient. Several possible reasons such as brain shift and impaired vascular autoregulation are also associated with postoperative AIH. We must be aware of this complication and keep some preventive measures in our mind.
Dynamic Modeling and Simulation of Electric Scooter Interactions With a Pedestrian Crowd Using a Social Force Model

In recent years, micro-mobility transport vehicles have become very popular. As a result, the challenge of developing new strategies and tools for the safety of users and pedestrians in shared travelways has attracted a lot of attention. Previous studies have generally used a social force model as the main tool for the prediction of pedestrian movements. However, existing models cannot be directly applied to wheeled vehicles such as electrical scooters. This study presents a modified social force model to predict the interactions of an electric scooter with a pedestrian crowd by considering the scooter’s kinematics constraints and geometry and the velocity-dependent behaviors of the rider. Moreover, experiments are performed to calibrate the parameters of the proposed model and compare it to an existing social force model. The experimental results demonstrate that the scooter social force model is superior to the original model due to its higher prediction accuracy. Using the scooter model with experimentally calibrated parameters, numerical simulations illustrate the behavior of an e-scooter rider in a pedestrian crowd. Acceleration and force metrics are introduced to evaluate the pedestrian comfort and safety. Monte Carlo simulations provide insights for urban planners about how travelway width, pedestrian density, and the e-scooter rider’s desired velocity affect pedestrian actual and perceived safety.
Remote Laser Welding of Zn Coated If Steel and 1050 Aluminium Alloy: Processing, Microstructure and Mechanical Properties

The integrity of steel-aluminium dissimilar alloy joints is dependent on the intermetallic phases (IMCs) and the extent of the bonding area. The excessive growth of brittle Al x Fe x IMCs within the weld pool and interfaces is disadvantageous due to the initiation and propagation of hot and cold cracking during the solidiﬁcation. The purpose of this work was to assess the development of Remote Laser Welded (RLW) joints of Zn coated inter-stitial free (IF) steel to 1050 aluminium alloy, which can be used in cooling circuits and electrical connectors in automotive applications. Welding experiments with variable RLW parameters (power, welding speed and focal offset) were performed to study the formation of IMCs and impact of joint integrity. Results showed that while in conduction mode (at power densities of 0.13 e 0.18 MW/cm 2 ) three IMCs were identiﬁed through SEM/EDX and EBSD: h e Al 5 Fe 2 , k e AlFe 3 and q e Al 13 Fe 4 which possessed nano-hardness indentation values of approximately 12, 5 and 5 GPa, respectively; they formed in a non-continuous interfacial layer, the weld pool composition remained homogenous, and cracking was minimal. On the contrary, in keyhole mode (at power densities of 0.16 e 0.40 MW/cm 2 ) welded samples produced a continuous and thick IMC layer, continuous and/or excessive cracking and an inhomogeneous weld pool composition due to the excessive mixing of steel and aluminium, of up to 10 wt. % of Al in the weld pool. The nominal lap shear strength for the sample produced in conduction mode was of 77%, with respect to the weakest joint material (Al). This work found a close link between the welding mode and weld pool chemistry which signiﬁcantly determined the IMCs distribution and thickness, extent of cracking within the weld pool and mechanical properties.
Phoenix Arising from the Ashes: An Event-Oriented Analysis of the Siemens' Corruption Scandal as Nexus between Organization and Society (Phönix aus der Asche: Eine ereignisorientierte Betrachtung des Siemens-Korruptionsskandals als Nexus zwischen Organisation und Umwelt) (German)

In our phenomenon-driven study we address mutual influences between a focal organization and its organizational environment. We draw on concepts and insights of new institutional theory as well as on the results of an extensive ethnographic field study of the 2006 to 2008 Siemens corruption scandal. We find that this event did not only result in considerable consequences for Siemens, but also culminated in a reevaluation of the phenomenon of corporate corruption with regard to its regulative, normative, and cultural-cognitive dimensions. It is therefore particularly suitable to analyze the various effects of institutional change on a focal organization like Siemens. Due to the momentum this scandal generated as well as due to the importance of Siemens our case makes it furthermore possible to analyze action patterns through which the focal company attempts to shape institutional change processes in its organizational environment subsequently to the scandal. According to our comprehension that change can only be assessed meaningfully from a process perspective we reconstruct the development of the institutional context of the phenomenon corruption as well as its effects on the focal company as a sequence of events. We do so by proposing a model which conceptualizes events as nexus between organizations and their organizational environment. Unsere phanomengetriebene Studie hat das wechselseitige Beeinflussungsverhaltnis von Organisation und organisationaler Umwelt zum Gegenstand. Gestutzt auf Konzepte und Erkenntnisse der neueren Institutionentheorie untersuchen wir im Rahmen einer ethnographischen Feldstudie den Siemens-Korruptionsskandal der Jahre 2006 bis 2008. Dieses Ereignis hatte nicht nur fur das betroffene Unternehmen erhebliche Konsequenzen, sondern hat auch zu einer Neubewertung des Phanomens organisa-tionaler Korruption in regulativer, normativer und kultureller Hinsicht gefuhrt, deren Konsequenzen sich erst langsam abzuzeichnen beginnen. Es eignet sich daher in besonderer Weise, die vielfaltigen Auswirkungen institutionellen Wandels auf eine fokale Organisation zu untersuchen. Sowohl aufgrund der Tragweite des Skandals, als auch ob der Bedeutung des involvierten Unternehmens ermoglicht es daruber hinaus eine Untersuchung der Handlungsmuster, durch die das betroffene Unternehmen den Wandel in seiner institutionellen Umwelt im Anschluss an den Skandal mitzugestalten versucht. Entsprechend unserer Uberzeugung, dass sich Wandel nur aus einer Pro-zessperspektive heraus adaquat erfassen lasst, rekonstruieren wir den sich andernden institutionellen Kontext des Phanomens Korruption sowie dessen Auswirkungen auf die fokale Organisation als Abfolge von Ereignissen in einem Modell, welches Ereignisse als Nexus zwischen einer fokalen Organisation und seiner Umwelt begreift (in German).
