Demonstration of a Multi‐Layer, Lithographically Manufactured Plasma Spectrometer

Development of new plasma instruments is needed to enable constellation‐ and small satellite‐based missions. Key steps in the development pathway of ultra‐compact plasma instruments employing lithographically patterned wafers are the implementation of layer‐to‐layer electrical interconnects and demonstration of massively parallel measurements, that is, simultaneous measurements through multiple identical plasma analyzer structures. Here we present energy resolved measurements of electron beams using a 5‐layer stack of wafer‐based, energy‐per‐charge, electrostatic analyzers. Each layer has eight distinct analyzer groups that are comprised of multiple micron scale energy‐per‐charge analyzers. The process of fabricating the electrical interconnects between the layers is described and the measured energy resolution and the angular resolution compared to theoretical predictions. The measurements demonstrate successful operation of 400 micron scale analyzers operating in parallel.
k-bitruss-Attributed Weighted Community Search on Attributed Weighted Bipartite Graphs

Community search on attributed weighted bipartite graphs is an essential problem and its aim is to retrieve high-quality communities containing a query vertex. An important evaluation metric to evaluate the quality of the output community is the attribute cohesiveness of the community search model on attributed weighted bipartite graphs. Nevertheless, the attribute cohesiveness of the existing community search model on attributed weighted bipartite graphs is relatively low, resulting in poor quality of the output communities. To retrieve high-quality communities for a query vertex on attributed weighted bipartite graphs, we propose a novel k-bitruss-Attributed Weighted Community model, where the structure cohesiveness is described by the k-bitruss model, and the attribute cohesiveness and the interaction cohesiveness is maximized. To support fast retrieval of k-bitruss-Attributed Weighted Community, we propose a new three-step approach. Under this three-step approach, a novel indexing technique and efficient algorithms are proposed to retrieve the k-bitruss-Attributed Weighted Community. We conduct comprehensive experiments on five real-world graphs, the experimental results demonstrate that the attribute cohesiveness of the k-bitruss-Attributed Weighted Community model surpasses all baselines and the attribute cohesiveness of the k bitruss-Attributed Weighted Community model exhibits greater stability compared to the existing community search model on attributed weighted bipartite graphs.
Formation of Macro Lead Using Plunge Grinding – a Kinematic Approach

Plunge grinding is considered to produce lead free surfaces for the usage with rotary shaft seals. The term “lead” summarizes all surface structures, which create a rotation dependent pumping effect. Since lead influences the complex tribological system “rotary shaft seal”, it is essential that the process “plunge grinding” manufactures surfaces without lead. A kinematic simulation model of the manufacturing process “plunge grinding” was developed to understand and visualize the complex interactions between the manufacturing parameters and the macro lead parameters on the surface. Additionally, an approach for the stochastic influence on the surface is also presented to investigate parameters for lead free surfaces. The model has been validated by the measurement of plunge ground parts with the same manufacturing parameters.
Coronary artery lesions in Takayasu arteritis

Introduction Takayasu arteritis (TAK) is a granulomatous inflammation of vessels of large diameter, mainly affecting the aorta and its proximal branches, which is more common in young women. The incidence of coronary artery disease in TAK is unknown and not sufficiently studied. Material and methods A literature review was performed for the period 2003 to 2023 using a search of the PubMed and Scopus scientific databases. We used the following key words to search the academic journal databases: “Takayasu arteritis”, “coronary angiography”, “myocardial revascularization”, “coronary artery disease”, “angina pectoris”, and “myocardial infarction”. Results The analysis of studies showed that coronary artery lesions (CAL) in TAK are not uncommon, being identified particularly in children and young individuals. Pathology of the coronary arteries increases the morbidity and mortality of TAK patients. In TAK, the ostia and proximal segments of the coronary arteries are more frequently affected, presenting as stenosis or occlusion with the development of stable coronary artery disease, unstable coronary artery disease, acute myocardial infarction, and sudden death. The diagnosis of TAK and coronary artery pathology is often complicated due to nonspecific manifestations and frequently the absence of symptoms. The treatment of patients with TAK with CAL is challenging and requires both pharmacological therapy and interventional or surgical methods of myocardial revascularization. Conclusions Takayasu arteritis is a more prevalent cause of CAL development, especially in young patients, than previously believed, and cardiovascular death due to CAL is not rare. Early diagnosis of TAK with CAL, particularly occlusion or hemodynamically significant stenosis, and the prompt initiation of appropriate treatment prevent dangerous complications, reduce mortality, and improve prognosis.
English Writing Mindsets and Feedback-Seeking Behaviors of Chinese College EFL Students

English writing effectively prompts learners to internalize the English language knowledge gained through reading and listening into their own linguistic and communicative competence, and thus comprehensively contributes to the improvement of their overall English language proficiency. English writing is the ultimate and most fundamental measure of students’ language proficiency. This study sought to investigate the relationship between English writing mindsets and feedback-seeking behaviors of selected Chinese EFL students. In this study, quantitative research was used. The respondents comprised 400 college students from three Chinese universities. Correlational analysis was used to handle the data that were gathered utilizing survey questionnaires. The results demonstrated that, on the whole, the participants tended toward a growth mindset in the setting of English writing mindset and that, by using monitoring or inquiry techniques and delaying feedback seeking, they had a favorable attitude toward feedback-seeking behaviors. Furthermore, the T-test findings indicated gender disparities in mindsets, with males having stronger growth mindset than females. Additionally, correlation analysis revealed a strong relationship between English writing mindsets and feedback-seeking behaviors. Students who frequently applied growth mindset also tended to have higher levels of feedback-seeking behaviors. Finally, pedagogical suggestions were put forward based on these findings.
Portugal’s Crowdfunding: A Systematic Literature Review

This study aims to analyze and classify the evolution of crowdfunding in Portugal from 2014 to 2020, addressing the central question, “What is the evolution of literature on crowdfunding and its research focuses in Portugal? ”. Additionally, it investigates, through the sub-question, if crowdfunding is perceived as an alternative form of financing. The methodology employs a systematic review, covering four thematic areas: (1) research focus—concepts; (2) research method—quantitative/qualitative identification; (3) geographical area—countries of study; (4) innovation—future research areas. The research begins with Google Scholar, followed by a more specific search of the B-On database, focusing on the Portuguese context. Results highlight the scarcity of research in Portugal, emphasizing the nascency of crowdfunding in the country. The study reveals the importance of investor behavior, influenced by platform security and regulations. Growth in crowdfunding in Portugal is anticipated, attracting multidisciplinary interest but emphasizing the need for more comprehensive studies. Despite limitations in data availability, the study provides valuable insights for entrepreneurs seeking alternative financing in Portugal, demonstrating crowdfunding as an alternative financing method. Integration of crowdfunding with technology, especially blockchain, is suggested as a potentially disruptive system, paving the way for future research and innovations.
Paleontology and stratigraphy of Middle Eocene rock units in the southern Green River and Uinta Basins, Wyoming and Utah

The Bridger Formation is restricted to the Green River Basin in southwest Wyoming, and the Uinta and Duchesne River Formations are located in the Uinta Basin in Utah. These three rock units and their diverse fossil assemblages are of great scientific importance and historic interest to vertebrate paleontologists. Notably, they are also the stratotypes from oldest to youngest for the three middle Eocene North American Land Mammal Ages—the Bridgerian, Uintan, and Duchesnean. The fossils and sediments of these formations provide a critically important record of biotic, environmental, and climatic history spanning approximately 10 million years (49 to 39 Ma). This article provides a detailed field excursion through portions of the Green River and Uinta Basins that focuses on locations of geologic, paleontologic, and historical interest. In support of the field excursion, we also provide a review of current knowledge of these formations with emphasis on lithostratigraphy, biochronology, depositional, and paleoenvironmental history, and the history of scientific exploration.
Procedurally just policing and persons in behavioral crises: investigating public perceptions, stigma and emotion

PurposeThe police often respond to persons who are not in direct violation of the law, but are rather undergoing behavioral crises due to mental illness or substance abuse disorders. The purpose of this study is to examine how police behavior influences civilian bystanders' emotional responses and perceptions of procedural justice (PPJ) when officers interact with these populations, which traditionally have been stigmatized in American culture.Design/methodology/approachUsing a factorial vignette approach, the authors investigate whether perceived public stigma moderates the relationship between police behaviors (i.e. CIT tactics, use of force) and PPJ. The authors also investigate whether emotional reactions mediate the relationship between police behaviors and PPJ.FindingsRegardless of suspect population (mental illness, substance use), use of force decreased participants' PPJ, and use of CIT tactics increased PPJ. These effects were consistently mediated by anger, but not by fear. Interactive effects of police behavior and perceived public stigma on PPJ were mixed.Originality/valueFear and anger may operate differently as antecedents to PPJ. Officers should note using force on persons in behavioral crisis, even if legally justifiable, seems to decrease PPJ. They should weigh this cost pragmatically, alongside other circumstances, when making discretionary decisions about physically engaging with a person in crisis.
Radar observations of density gradients, electric fields, and plasma irregularities near polar cap patches in the context of the gradient‐drift instability

We present observations of plasma density gradients, electric fields, and small‐scale plasma irregularities near a polar cap patch made by the Super Dual Auroral Radar Network radar at Rankin Inlet (RKN) and the northern face of Resolute Bay Incoherent Scatter Radar (RISR‐N). RKN echo power and occurrence are analyzed in the context of gradient‐drift instability (GDI) theory, with a particular focus on the previously uninvestigated 2‐D dependencies on wave propagation, electric field, and gradient vectors, with the latter two quantities evaluated directly from RISR‐N measurements. It is shown that higher gradient and electric field components along the wave vector generally lead to the higher observed echo occurrence, which is consistent with the expected higher GDI growth rate, but the relationship with echo power is far less straightforward. The RKN echo power increases monotonically as the predicted linear growth rate approaches zero from negative values but does not continue this trend into positive growth rate values, in contrast with GDI predictions. The observed greater consistency of echo occurrence with GDI predictions suggests that GDI operating in the linear regime can control basic plasma structuring, but measured echo strength may be affected by other processes and factors, such as multistep or nonlinear processes or a shear‐driven instability.
First natural occurrence of the entomopathogenic fungus Beauveria bassiana (Bals. Criv.) Vuill. on Cosmopolites sordidus (Germar, 1824) (Curculionidae, Coleoptera) in an agroforestry system in the Brazilian Cerrado

The natural occurrence of the fungus Beauveria bassiana is an indicator of environmental balance. When the agroforestry system naturally presents this entomopathogenic fungus on the banana weevil Cosmopolites sordidus, a pest insect in the banana crops, it reinforces the beneficial effects of this agroecosystem. Thus, this work reports the first natural occurrence of B. bassiana on C. sordidus for the agroforestry system and the Cerrado biome. The natural occurrence of this parasitic relationship indicates that the agroforestry system may favor the fungal occurrence and spread.
Early Childhood Education during conflict and change: Learning from the World War 2 experience of Breslau, Germany/Wroclaw, Poland

This research explores Early Childhood Education (ECE) during an intensely chaotic historical period in one city in Eastern/Central Europe. Breslau, initially a German city, was transferred to Poland and renamed Wroclaw in 1945 after World War 2. Breslau/Wroclaw experienced intense upheaval before, during, and after the war including the almost complete physical devastation of the city and the ensuing massive migration from the expulsion of ethnic Germans and the resettlement of Poles from eastern regions. The impact of war and government policies on the development and continuance of Early Childhood Education as Hitler and National Socialism rose to power, during the months of uncertainty around the end of the war, and on the establishment of a new system of Early Childhood Education in Wroclaw under Soviet domination receive focus in this paper. The results and discussion are applied to contemporary circumstances such as the current crisis in Ukraine, as well as social and political upheaval arising from other emergencies.

A study was done in Kut City (Iraq), for detection incidence of Salmonella spp. in local and imported eggs samples. For that purpose 120 samples of eggs, (60) local, (60) imported were obtained from local markets during the period from the February up to May 2012. As results, Salmonella spp. was detected in 54 of 120(45%) local and imported eggs: 30 of 60 (50%) local eggs and 24 of 60 (40%) imported eggs. The prevalence of Salmonella spp in local and imported samples varied between year months with the highest prevalence occurring in May (68.7%) in local and (62.5) in imported eggs. The results of statistical analysis showed significant differences (P>0.05) between local and imported samples of eggs, and there was statistically significant difference (P>0.05) between the months year in prevalence of Salmonella in imported and local eggs. The results of this study showed that eggs are a significant source for Bacterial food poisoning that concerns the public health in Iraq.
A High-Selectivity Filtering Antenna Based on Dual-Post Coaxial Resonators

In this communication, a compact waveguide filtering antenna is designed using dual-post coaxial resonators. The dual-post coaxial resonator consists of a pair of identical metal posts, capable of generating two resonant modes with identical and opposite electric field directions, respectively. The coupling post structure is employed to excite the two modes to achieve positive coupling and negative coupling. The combination of different dual-post coaxial resonators can be used to design higher order filters with transverse topology, realizing multiple transmission zeros. Furthermore, additional transmission zeros can be generated through direct coupling between the source and load, resulting in enhanced out-of-band rejection performance. A fourth-order waveguide filtering antenna is fabricated and measured, achieving high-selectivity performance.
The Impacts of Quality Management Success Factors on the Quality Performance of Construction Projects in the Lake Chad Basin

In the Lake Chad Basin, the drivers of poor-quality performance of construction projects are multi-dimensional, which are compounded with issues related to insecurity and climate change. In the North-Eastern region of Nigeria, an estimated US$ 3.3 Billion was the cost of damages to housing and other public building infrastructures, with an estimated US$ 1.2 Billion needed for reconstruction and repairs to the damaged infrastructures due to activities of various terrorist organizations. Therefore, there is need to deliver projects of high standards as well as to device means to continuously assess their performance throughout the project life-cycle. Hence, this survey examined: the relative impacts of quality management success factors, and determined their effects on the quality performances of construction projects in the region. The study is limited in scope to the Anglophone speaking part of the region. A total of 80 questionnaires were distributed using both a convenience and snowball sampling techniques to the available respondents, ably represented by construction professionals with vast knowledge and years of working experience in the Nigeria’s state of Yobe, being a frontline state in the Lake Chad Basin, and 59 of the questionnaires were successfully retrieved, and analysis was done with the aid of SPSS, a social science analysis software. Findings indicates that, the quality management success factors with the highest relative severity index on the quality performance are: project manager’s previous work experience and supervision skills; project manager’s technical competence and good leadership skills; taking appropriate security measures on project site; project planning, monitoring and evaluation; project team technical capabilities; completeness and consistency of design document; and clear and well detailed contract documents. The quality management success factors will have an overall 59.7% significant cause-effects influence on the quality performances of construction projects in the region. Further findings revealed that, the most significantly impacted quality performance measures, are: minimal or absence of rework; time taking in rectifying defective components and services; satisfaction by end users’, customers and stakeholders; absence of observable defects after project completion; cost of rectifying defective components and services. This study has added to the existing body of knowledge, and has succeeded in bringing to light quality management success factors that are peculiar and applicable to areas devasted with challenges of insecurity and climate change.
The Use of Noninvasive Velacur® for Discriminating between Volunteers and Patients with Chronic Liver Disease: A Feasibility Study

Background and Aims Nonalcoholic fatty liver disease is the leading cause of chronic liver disease globally and can progress to cirrhosis, liver failure, and liver cancer. Current AASLD, AGA, and ADA guidelines recommend assessment for liver fibrosis in all patients with NAFLD. Serum biomarkers for fibrosis, while widely available, have notable limitations. Imaging-based noninvasive testing for liver fibrosis/cirrhosis is more accurate and is becoming more widespread. Methods We evaluated the feasibility of a novel shear wave absolute vibroelastography (S-WAVE) modality called Velacur® for assessing liver stiffness measurement (LSM) for fibrosis and attenuation coefficient estimation (ACE) in differentiating patients with chronic liver disease from normal healthy controls. Results Fifty-four healthy controls and 89 patients with NAFLD or cured HCV with a prior known LSM of >8 kPa were enrolled, and all subjects were evaluated with FibroScan® and Velacur®. Velacur® was able to discriminate patients with increased liver stiffness as determined by a FibroScan® score of >8 kPa from healthy controls with an AUC of 0.938 (0.88-0.96). For assessment of steatosis in NAFLD patients only, Velacur® could identify patients with steatosis from healthy controls with an AUC of 0.831 (0.777-0.880). The Velacur® scan quality assessment was superior in healthy controls, as compared to patients, and the scan quality, as assessed by the quality factor (QF) and interquartile range (IQR)/median, was affected by BMI. Velacur® was safe and well tolerated by patients, and there were no adverse events. Conclusion Velacur® assessment of liver stiffness measurement and liver attenuation is comparable to results obtained by FibroScan® and is an alternative technology for monitoring liver fibrosis progression in patients with chronic liver disease. This trial is registered with NCT03957070.
Conceptual Design of a Solid State Telescope for Small scale magNetospheric Ionospheric Plasma Experiments

The present paper describes the design of a Solid State Telescope (SST) on board the Korea Astronomy and Space Science Institute satellite-1 (KASISat-1) consisting of four [TBD] nanosatellites. The SST will measure these radiation belt electrons from a low-Earth polar orbit satellite to study mechanisms related to the spatial resolution of electron precipitation, such as electron microbursts, and those related to the measurement of energy dispersion with a high temporal resolution in the sub-auroral regions. We performed a simulation to determine the sensor design of the SST using GEometry ANd Tracking 4 (GEANT4) simulations and the Bethe formula. The simulation was performed in the range of 100 ~ 400 keV considering that the electron, which is to be detected in the space environment. The SST is based on a silicon barrier detector and consists of two telescopes mounted on a satellite to observe the electrons moving along the geomagnetic field (pitch angle 0°) and the quasi-trapped electrons (pitch angle 90°) during observations. We determined the telescope design of the SST in view of previous measurements and the geometrical factor in the cylindrical geometry of Sullivan (1971). With a high spectral resolution of 16 channels over the 100 keV ~ 400 keV energy range, together with the pitch angle information, the designed SST will answer questions regarding the occurrence of microbursts and the interaction with energetic particles. The KASISat-1 is expected to be launched in the latter half of 2020.
