Online Trajectory Planning Method for Double-Pendulum Quadrotor Transportation Systems

This study investigates the trajectory planning problem for double-pendulum quadrotor transportation systems. The goal is to restrain the hook swing and payload swing while achieving precise positioning. An online trajectory planning method with two capabilities—precise positioning and swing suppression—is proposed. The stability and convergence of the system are proved using the Lyapunov principle and the LaSalle’s invariance theory. Simulation results show that the proposed method has excellent control performance.
A meta-analysis study on the attitudes of pre-service music teachers towards the teaching profession in Turkey

The objective this study was to determine whether music teacher candidates’ attitudes towards the teaching profession in Turkey differ with respect to different variables. In this direction, a meta-analysis study was carried out on the pre-service music teachers’ attitudes towards their profession. The study consists of 12 studies chosen with predetermined criteria. Since the effect sizes of these studies display a heterogeneous structure, the random effects model was conducted. Effect sizes in the random effects model were calculated by using Hedges g coefficient with 12 studies for gender and nine studies for the form of high school graduated. Taking the results of the findings into consideration, it was concluded that the attitudes of female music teacher candidates towards the teaching profession are more positive than male candidates. There is no difference between Fine Arts and other high schools regarding the variable of the form of high school.
An increase in cases of complicated chronic otitis media: an indirect impact of COVID pandemic

Background: Chronic otitis media is the most common disease dealt by an otologist, the cases of complication of which are remarkably low. The use of antibiotics and mastoidectomies have resulted in the fall of the fatal complications. COVID-19 pandemic called for restrictions which lead to medical care delay.Methods: This study was conducted in the department of otolaryngology of GMC and associated hospitals, Jammu from June 2020 and May 2021. The data was retrospectively collected the data from March 2018 to June 2020. The study group included the patients diagnosed with Chronic suppurative otitis media (CSOM) on otoscopy and the patients with complications of CSOM were evaluated for the symptoms of complication, type of complication, bacteriology, treatment and hospital stay.Results: The 38 (7.5%) patients among these were diagnosed with one or other complication, out of which 29 (76.3%) cases occurred during the COVID pandemic. The extra-cranial complications were more common and young to middle age group was more commonly involved.Conclusions: COM is a common otological disease, the occurrence of which should not be taken lightly. Without timely and accurate treatment, the complications ensue which are difficult to treat and require expertise.
Progress testing and its effect on medical student motivation

Assessment has a pivotal role in medical education, as it can direct student learning. Motivation is an essential factor that determines learning assessment results. One of the aims of assessment is to determine the level of student knowledge, one of which can be measured by a progress test. This study aimed to determine the relationship between progress test and student motivation. This study used a cross-sectional observational analytic method. It was conducted in 2017 at Faculty of Medicine Universitas Sebelas Maret (FM UNS), Indonesia. The respondents consisted of 253 students from batch 2014, 2015, and 2016. The sample was selected by stratified random sampling. The instrument used to assess academic motivation was the academic motivation scale (AMS). The research data were analyzed using the Pearson correlation test. There is a significant positive correlation between progress test results and academic motivation (r=0.500; p=0.000). However, there is no significant difference in motivation level based on gender (p=0.889) and student cohort (p=0.533). In the progress test score, there are significant differences based on gender (p=0.014) and grade-point average (p=0.000). However, there is no significant difference in the progress test scores based on the student batch (p=0.212). The results support that progress test is useful assessment method to support medical student’s motivation.
Towards a Quantitative Cartography of the Grain Boundary Energy Landscape: Paths and Correlations

We apply a newly developed Voronoi fundamental zone (VFZ) framework to gain insights about grain boundary (GB) structure-property relationships in the five degree-of-freedom (5DOF) space of cubic GBs. We analyze the shape and size of a 5DOF fundamental zone (FZ), molecular statics energy uncertainty, property similarity of GBs that are crystallographically \close" (i.e. correlations), and energy pathways through 5DOF space. Considered together, these insights are important for managing tradeoffs between accuracy, complexity, and design considerations for electron backscatter diffraction/serial sectioning, high-energy diffraction microscopy, molecular statics, and density-functional theory. In terms of the shape and size of a 5DOF FZ, we discover that a FZ is smaller than expected at only ∼65° in the largest principal component. Thus, a 10° difference between two GBs, which may have previously been considered small, is actually quite large. We represent a GB by five transformed Cartesian coordinates equipped with a Euclidean distance metric. Using this representation, we find that the FZ has a low aspect-ratio shape (i.e. width, length, height, etc. are similar) which is important for 5DOF numerical differentiation. Semivariogram and numerical optimization methods reveal that grain boundary energy (GBE) in Ni and Fe are globally correlated within ∼6° to 8° in the grain boundary octonion (GBO) sense (multiply by 2 to convert to misorientation angle). For local correlation lengths of high-symmetry GBs of interest, we notice significant variation relative to global correlation lengths and an inverse relationship with the Brandon criterion. We suggest that property data with no more than ± ∼3 % error and point sets with GBs that are no more than ∼3−4° apart should be used and then paired with high-fidelity interpolation strategies. Finally, in terms of dynamic material behavior, geodesic paths through 5DOF space for Ni suggest that, under appropriate conditions, a certain low-energy Σ7 GB may transform into the frequently observed Σ3 coherent-twin GB which may be interesting to verify by experiment or simulation.
An early Cambrian polyp reveals an anemone-like ancestor for medusozoan cnidarians

Extant cnidarians are a disparate phylum of non-bilaterians and their diploblastic body plan represents a key step in animal evolution. Anthozoans (anemones, corals) are benthic polyps, while adult medusozoans (jellyfishes) are dominantly pelagic medusae. A sessile polyp is present in both groups and is widely conceived as the ancestral form of their last common ancestor. However, the nature and anatomy of this ancestral polyp, particularly of medusozoans, are controversial, owing to the divergent body plans of both groups in the extant lineages and the rarity of medusozoan soft tissues in the fossil record. Here we redescribe the enigmatic Conicula striata Luo et Hu from the early Cambrian Chengjiang biota, south China, which has previously been interpreted as a polyp, lophophorate or deuterostome. We show that C. striata possessed features of both anthozoans and medusozoans. Its stalked polyp and fully encasing conical, annulated organic skeleton (periderm) are features of medusozoans. However, the gut is partitioned by ∼28 mesenteries, and has a tubular pharynx, resembling anthozoans. Our phylogenetic analysis recovers C. striata as a stem medusozoan, indicating that the enormously diverse medusozoans were derived from an anemone-like ancestor, with the pharynx lost and number of mesenteries reduced prior to the origin of crown group Medusozoa.
Evaluation of Co-compost of Oil Palm Empty Fruit Bunch and Cow Dung as Fertilizer in Oil Palm Nurseries

Oil palm empty fruit bunch (EFB) is one of the readily available crop residues that can serve as cheap organic fertilizer source for crop. EFB-cow dung composts (EFB: cow dung ratios of 100:0, 80:20, 60:40, and 0:100) pre-treated by soaking in water, unsoaked and sole cow dung (all on dry weight basis) were incubated in an Alfisol under laboratory conditions for 10 months. These treatments were also used to raise oil palm seedlings in the nursery. Nutrient release pattern of unsoaked EFB: cow dung (60:40) was significantly (p<0.05) better than other EFB compost treatments. Correlation coefficient (r) between phosphorus released and ECEC with time of incubation were 1.00 and 0.98 (p<0.01) respectively. Unsoaked EFB cow dung (60:40) was as effective as mineral NPKMg fertilizer in enhancing plant dry matter accumulation and nutrient uptake.
Antiangiogenic Compound Axitinib Demonstrates Low Toxicity and Antitumoral Effects against Medulloblastoma

Simple Summary Medulloblastoma is the most frequent pediatric brain cancer. Despite great improvements in the treatment of this disease over the last decades, survivors are subject to debilitating adverse effects that strongly impair their quality of life. There is an urgent need to find efficient anticancer therapies with fewer toxic effects. In this study, we suggest that an FDA- and EMA-approved antiangiogenic compound named axitinib may display effective antitumoral effects and low toxicity towards children as compared to a reference treatment currently used in clinical protocols. We also show that this compound can enter the brain compartment and exert antitumoral effects in vivo. Our study paves the way towards a clinical trial of repurposing axitinib to a pediatric brain cancer indication. Abstract Background: Despite the improvement of medulloblastoma (MB) treatments, survivors face severe long-term adverse effects and associated morbidity following multimodal treatments. Moreover, relapses are fatal within a few months. Therefore, chemotherapies inducing fewer adverse effects and/or improving survival at relapse are key for MB patients. Our purpose was to evaluate the last-generation antiangiogenic drugs for their relevance in the therapeutic arsenal of MB. Methods: We screened three EMA- and FDA-approved antiangiogenic compounds (axitinib, cabozantinib and sunitinib) for their ability to reduce cell viability of five MB cell lines and their low toxicity towards two normal cell lines in vitro. Based on this screening, single-agent and combination therapies were designed for in vivo validation. Results: Axitinib, cabozantinib and sunitinib decreased viability of all the tested tumor cells. Although sunitinib was the most efficient in tumor cells, it also impacted normal cells. Therefore, axitinib showed the highest selectivity index for MB cells as compared to normal cells. The compound did not lead to acute toxicity in juvenile rats and crossed the blood–brain barrier. Moreover, axitinib efficiently reduced the growth rate of experimental brain tumors. Analysis of public databases showed that high expression of axitinib targets correlates with poor prognosis. Conclusion: Our results suggest that axitinib is a compelling candidate for MB treatment.
An application of the integrated AHP-PGP model for performance measurement of supply chain management

The performance measurement problem has gained great attention in business and operations management literature. The first objective of this study is to determine the required performance measures and to develop a model for performance evaluation, based on these selected measures using analytical hierarchy process (AHP) methodology. The second objective is to explain how an integrated AHP-PGP (pre-emptive goal programming) model can be used in performance measurement while optimising the overall performance. An integration of AHP and multi-objective PGP is used to consider both quantitative and qualitative performance measures in optimising the overall performance of the system. The integrated model is presented with a real-world application using source data provided by a survey conducted in India. Findings demonstrate that the integrated AHP-PGP model can be useful to all supply chain industries in their day-to-day performance measurement decisions.
Changes in the Polyphenolic Profile and Antioxidant Activity of Wheat Bread after Incorporating Quinoa Flour

Quinoa is a trend and a promising functional food ingredient. Following previous research into the impact of incorporating quinoa flour on the polyphenol content and antioxidant activity of bread, this study aimed to bridge an existing gap about the qualitative and quantitative polyphenolic profiles of such bread. The UPLC-MS/MS analysis showed that quinoa bread, made with 25% quinoa flour of a black variety, presented more compounds than refined-wheat bread, and levels were remarkably higher in many cases. Consequently, the quinoa bread presented clearly improved polyphenolic content than the wheat bread (12.8-fold higher considering the sum of extractable and hydrolyzable polyphenols), as supported by greater antioxidant activity (around 3-fold). The predominant compounds in the extractable fraction of quinoa bread were p-hydroxybenzoic acid and quercetin (50- and 64-fold higher than in wheat bread, respectively) and rutin (not detected in wheat bread), while ferulic and sinapic acids were the most abundant compounds in the hydrolyzable fraction (7.6- and 13-fold higher than in wheat bread, respectively). The bread-making impact was estimated, and a different behavior for phenolic acids and flavonoids was observed. Extractable phenolic acids were the compounds that decreased the most; only 2 of 12 compounds were enhanced (p-hydroxybenozoic and rosmarinic acid with increments of 64% and 435%, respectively). Flavonoids were generally less affected, and their concentrations considerably rose after the bread-making process (7 of the 13 compounds were enhanced in the extractable fraction) with especially noticeably increases in some cases; e.g., apigenin (876%), kaempferol (1304%), luteolin (580%) and quercetin (4762%). Increments in some extractable flavonoids might be explained as a consequence of the release of the corresponding hydrolyzable forms. The present study provides new information on the suitability of quinoa-containing bread as a suitable vehicle to enhance polyphenols intake and, hence, the antioxidant activity in daily diets.
The house of reliability

Purpose – The purpose of this paper is to provide a structured methodology for performing build‐in reliability (BIR) investigation during a new product development cycle.Design/methodology/approach – The methodology in this paper represents an extension of the Quality Functional Deployment/House of Quality (QFD/HoQ) concepts to reliability studies. It is able to translate the reliability requisites of customers into functional requirements for the product in a structured manner based on a Failure Mode And Effect Analysis (FMEA). Besides, it then allows it to build a completely new operative tool, named House of Reliability (HoR), that enhances standard analyses, introducing the most significant correlations among failure modes. Using the results from HoR, a cost‐worth analysis can be easily performed, making it possible to analyse and to evaluate the economical consequences of a failure.Findings – The paper finds that the application of the proposed approach allows users to identify and control the design.
Modelling customer satisfaction for product development using genetic programming

Product development involves several processes in which product planning is the first one. Several tasks normally are required to be conducted in the product-planning process and one of them is to determine settings of design attributes for products. Facing with fierce competition in marketplaces, companies try to determine the settings such that the best customer satisfaction of products could be obtained. To achieve this, models that relate customer satisfaction to design attributes need to be developed first. Previous research has adopted various modelling techniques to develop the models, but those models are not able to address interaction terms or higher-order terms in relating customer satisfaction to design attributes, or they are the black-box type models. In this paper, a method based on genetic programming (GP) is presented to generate models for relating customer satisfaction to design attributes. The GP is first used to construct branches of a tree representing structures of a model where interaction terms and higher-order terms can be addressed. Then an orthogonal least-squares algorithm is used to determine the coefficients of the model. The models thus developed are explicit and consist of interaction terms and higher-order terms in relating customer satisfaction to design attributes. A case study of a digital camera design is used to illustrate the proposed method.
Survival of Women Previously Diagnosed of Melanoma with Subsequent Pregnancy: A Systematic Review and Meta-Analysis and a Single-Center Experience

Melanoma incidence has increased over the last few decades. How the prognosis of a previously diagnosed melanoma may be affected by a woman’s subsequent pregnancy has been debated in the literature since the 1950s, and the outcomes are essential to women who are melanoma survivors in their childbearing years. The main objective of this systematic review is to improve the understanding of whether the course of melanoma in a woman may be altered by a subsequent pregnancy and to help clinicians’ diagnosis. Eligible studies for the systematic review were clinical trials, observational cohort studies and case-control studies that compared prognosis outcomes for non-pregnant patients with melanoma, or pregnant before melanoma diagnosis, versus pregnant patients after a diagnosis of melanoma. The search strategy yielded 1101 articles, of which 4 met the inclusion criteria for the systematic review. All the studies were retrospective non-randomised cohorts with patients with melanomas diagnosed before pregnancy. According to our findings, a subsequent pregnancy was not a significant influence on the outcome of a previous melanoma. However, given the small number of identified studies and the heterogeneous data included, it is recommended to approach these patients with caution, and counselling should be given by known prognostic factors. We also reviewed the medical records of 84 patients of childbearing age (35.8 ± 6.3 years, range 21–45 years) who were diagnosed with cutaneous invasive melanoma in our hospital between 2008 and 2018 (N = 724). Of these, 11 (13.1%) had a pregnancy after melanoma diagnosis (age at pregnancy: 35.6 ± 6.3 years). No statistical differences in outcome were detected.
Modeling of Fuel Consumption Rate for Agricultural Tractors

A mathematical model was developed to predict the fuel consumption rate consumed by agricultural tractors under arbitrary loaded conditions. The model utilizes the measured data on the fuel consumptions at the full load and at the rated engine speed with partial loads, which can easily be obtained from the official OECD tractor test reports. It was found from the analysis of the measured fuel consumption data that the fuel consumptions at two different speeds does not change with power. The model was developed based on this fact and validated with the measured data of the 159 tractor test reports. The fuel consumptions predicted by the model were compared with those measured under the partially loaded conditions specified in the official OECD tractor test code II. The percent errors of the predicted fuel consumptions were in a range from 0.36 to 2.86% which assured that the developed fuel consumption model can be used practically to predict the fuel consumptions at any speed and power combinations. It was also shown that the developed model predicts the fuel consumption rate better than the Grisso`s model.
Soliton Transmission in Fibers with Polarization-Mode Dispersion

Abstract The polarization-mode dispersion (PMD) is a dominant statistical effect in ultra-high bit rate transmission systems. In this article, soliton transmission in constant and randomly varying birefringent fibers is reviewed. In particular, soliton robustness to PMD is analyzed and compared with that of linear pulses. It is found that solitons broaden in proportion to the square root of distance, like in the case of linear pulses, but with a reduced coefficient.
Sources of gender differences in competency beliefs and retention in an introductory
 premedical
 science course

Gender disparities in retention in pathways to science continue to vary widely by course. Undergraduates intending to study prehealth and premedicine often represent a majority of students enrolled in introductory science courses, contribute to a large number of eventual science degree earners, and are a population that typically includes a high number of women. However, gender differences in attrition, grades, and attitudes persist in the introductory science courses required by undergraduate preheath and premedical programs, particularly within the physical sciences (i.e., Chemistry and Physics). We use structural equation modeling to study 416 undergraduate students across multiple sections of an Algebra-based Physics course, a common course on the prehealth and premedical track where large gender differences in grades, retention and competency beliefs have been documented. Our analysis focuses on identifying potential academic and attitudinal sources for gender differences in students' beliefs about their Physics abilities at the end of the course, and retention to the second physics course, which is often influenced by these competency beliefs. Results suggest that while men's ability beliefs in Physics are relatively stable and largely derived from early performance indicators, this is a smaller source of ability beliefs for women. Instead, women's ability beliefs are mediated during the course through their sense of belonging in Physics, and the extent to which they believe that Physics ability is fixed or malleable. These findings can inform the design of interventions in Physics courses that specifically target the development of ability beliefs for women intending medical careers.
Contractor Prequalification in Saudi Arabia

The process of investigating and qualifying contractors is important to ensure the success of construction projects. Prequalification has been established as a standard practice by public and semipublic organizations. Its objective is to ensure that the contractor's characteristics and capabilities match the requirements of the project under consideration. Effective and objective qualification processes serve both owners and contractors. Construction is a worldwide industry. The extension of the General Agreement on Tariffs and Trade (GATT) agreement in the construction industry in the near future will make it possible for contractors to bid in different parts of the world. This paper identifies criteria that are considered in prequalification practices for semipublic and private projects in Saudi Arabia. Prequalification practices of 19 large companies were studied. In addition, questionnaires were sent to 202 randomly selected companies. The results indicated that common criteria for evaluation include:.
