Machine learning the lattice constant of cubic pyrochlore compounds
Authors: Zhang Yun , Xu Xiaojie 
Published: January 2021

AbstractPyrochlores, with a general formula A2B2X7, are promising candidates in many potential applications due to their wide varieties of physical properties. Different combinations of cations and anions in the crystal structure enable the tailoring of their properties and functionalities. For cubic pyrochlores, the lattice constant, a, is an integrated result of stoichiometry, ionic radii, and electronegativities of alloying elements. It also has significant impacts on stabilities, electronic structures, ionic conductivities, and thus performance of materials. Here, we develop the Gaussian process regression model to shed light on the relationship among ionic radii, electronegativities, and lattice constants for cubic pyrochlores. The dataset includes ternary pyrochlores and mixed pyrochlores with co‐doping and multi‐doping situations. One hundred and thirty‐nine samples with lattice constants between 9.287 and 11.150 Å are examined. The model is highly stable and accurate that contributes to efficient and low‐cost lattice constant estimations.

SummaryPassion fruit is the fourth most consumed fruit by the Brazilian population, especially in the form of juice, usually associated with the addition of sucrose. This study aimed to evaluate the ideal sucrose concentration, and its impact on the consumer's acceptance of passion fruit nectar, sweetened with non‐caloric sweeteners as sucrose replacers in five Brazilian geographic regions. The acceptance scores evaluated by anova and Tukey's Honestly Significant Difference test indicated that sucralose‐sweetened samples were the most accepted, with no differences from the sucrose‐sweetened sample (P < 0.05), with a positive purchase intention in the five regions studied (>50%). However, differences in the acceptance scores were observed for the other sweeteners among the regions. Despite the difference in the sweetness perception among the Brazilian geographic regions, it may not be the only determining factor in the acceptance of passion fruit nectar sweetened with non‐caloric sweeteners.

SummaryThe study investigated the feasibility of using a combination of near‐infrared hyperspectral imaging (NIR‐HSI) with two‐dimensional correlation (2DCOS) analysis for rapid and non‐destructive determination of the content of biogenic amines in mutton during refrigerated storage. Total contents of biogenic amines (TBA) were used as the perturbation. By analysing the synchronous and asynchronous two‐dimensional correlation spectra, sensitive variables that were closely related to TBA contents were obtained. The results showed that the wavelengths in the spectra range of 1002–1335 nm were the research area for the detection of TBA contents in mutton. The least‐squares support vector machines (LSSVM) model based on effective wavelengths selected by competitive adaptive reweighted sampling (CARS) from 2DCOS analysis showed excellent results, with correlation coefficient in prediction (Rp) of 0.91, root mean square error in prediction (RMSEP) of 1.67 mg kg−1 and the ratio of performance deviation (RPD) of 2.76. The research demonstrated that the combination of NIR‐HSI and 2DCOS could be used as an effective method for monitoring the content of biogenic amines in mutton.
Development and characterisation of gluten‐free potato bread
Authors: Lu Zhan‐Hui , Donner Elizabeth , Liu Qiang 
Published: January 2021

SummaryThe aim of this study was to develop a novel and entirely potato‐based staple bread. Bread‐making performance of individual potato components (starch, protein and fibre) were independently evaluated and optimised by their ternary mixture. Flours from yellow and purple potatoes were then incorporated up to 25% of full formula weight to maximise the utilisation of resources. Fresh tuber was further added up to 50% for the full benefits from potatoes. The excessive oven‐rising after the crust hardened was manipulated by delicately balancing the strong swelling power of potato starch, which effectively resolved the cracks on the crust. The resultant potato breads showed a typical bread appearance, loaf size, low porosity but high cell density crumb structure and unique favourable sensory qualities, especially those with 2% potato fibre or 30% fresh tuber. Potato breads staled quickly during storage, but reheating could reverse the bread staleness to a nearly freshly baked state.

Published: January 2021

SummaryThis study investigates distribution of three micronutrients in milling streams of three common wheat cultivars to estimate nutritive value of white and brown flours. Among the analysed wheat cultivars, the majority of flour streams of NS Todorka showed a higher content of soluble micronutrients than the other two investigated wheat cultivars. It is necessary to improve bioavailability of Fe and Zn in flours since these micronutrients were mostly in insoluble form. In contrast, considering average Serbian portion sizes for bread, bread made from flour Type ‘110’ could supply almost 75% of the recommended daily intake for Mn.

SummaryUltimate pH (pHu) is an indicator that influences post‐mortem meat quality. We studied physiological and biochemical changes of steaks obtained from Nellore bulls (Bos indicus) during post‐mortem ageing. To this, Longissimus lumborum (LL) muscles were classified into three groups: Normal‐pHu (≤5.79), Intermediate‐pHu (5.80–6.29) and High‐pHu (≥6.30) groups, portioned into steaks, vacuum packaged and matured at 2 °C for 0, 7, 14, 21 and 28 days. High‐pHu steaks exhibited impaired colour stability and were darker compared to the other groups. High‐ and Normal‐pHu steaks showed improved tenderness and myofibrillar fragmentation linked to proteolysis. Intermediate‐pHu steaks were associated with a lower meat tenderness and decreased collagen solubility. High‐pHu steaks retained a high pH during ageing and increased water‐holding capacity. These findings provide evidence that highlight pHu as a strategy for the classification of pHu‐dependent beef quality from Nellore bulls that can be adopted by the Brazilian meat industry.
Effect of starch and non‐starch components on water migration, microstructure, starch retrogradation and texture of flat rice noodles made from different rice varieties

Published: January 2021

SummaryEffects of starch and non‐starch components on rice noodle quality, water migration during rehydration, texture, microstructure and starch retrogradation of dried rice flour and rice starch noodles made from five rice varieties with similar high amylose contents were examined. Rice noodle qualities depended mainly on starch properties and to a lesser extent on the presence of non‐starch components. Elongation of rice flour noodles was lower than rice starch noodles due to the presence of non‐starch components that interrupted the starch network. Non‐starch components reduced cooking loss of flour noodles in some varieties. Water migration in rice flour noodles with a looser microstructure was faster than in rice starch noodles. Nuclear magnetic resonance imaging revealed different water migration speeds in rice flour noodles among varieties, related to noodle microstructure and retrogradation properties. For production of good quality rice noodles, manufacturers should consider not only amylose content but also non‐starch components.
Phenolic, apparent antioxidant and nutritional composition of quinoa (Chenopodiumquinoa Willd.) seeds

Published: January 2021

AbstractQuinoa, a gluten‐free pseudocereal, has a nutrient and phytochemical profile which may benefit health. Our aim was to investigate the variability in the phenolic and apparent antioxidant content of different quinoa varieties to identify a variety with a high phytochemical content to use in a quinoa‐enriched bread. The results showed that free phenolics contributed most (50–83%) to total phenolic content compared with conjugated or bound forms. Apparent antioxidant activities measured by FRAP, ABTS+• and DPPH of free, conjugated and bound extracts were broadly similar, except for free antioxidants when determined by FRAP, which were higher. Phenolic content was positively correlated with FRAP and ABTS+• apparent antioxidant activity. Quinoa samples had a high protein content (13.5 g/100 g dry weight), with a well‐balanced amino acid profile. Incorporation of quinoa into baked products such as bread is proposed as a way to deliver this healthy whole‐grain cereal into the diet.

AbstractIntroductionMinimal residual disease (MRD) is a cornerstone for stratification of upfront B‐lymphoblastic leukemia (B‐ALL) treatment protocols to decrease relapse risk. Although its detection by flow cytometry (FC) and real‐time quantitative polymerase has clinical usefulness, evidence suggests that methods with increased sensitivity could lead to improved outcomes. The aim of this study was to develop an amplicon‐based assay followed by high‐throughput sequencing of the immunoglobulin heavy chain variable region for MRD detection in B‐ALL.MethodsWe analyzed 84 samples, 27 from diagnosis, 5 from relapse, 40 from post‐treatment samples, and 12 from healthy controls.ResultsOur assay was able to identify more neoplastic clones at diagnosis than Sanger sequencing including incomplete DJ rearrangements. From the 40 MRD samples evaluated 21 were positive by our new approach on high‐throughput sequencing assay, but only 15 of these were positive by FC. The remaining 19 were negative by the two techniques.ConclusionWe have developed a novel approach on high‐sensitive assay for MRD detection in B‐ALL, which could add clinical value in the management of patients, especially in cases negative for MRD by FC.

SummaryBackgroundPersistent household food insecurity may have a greater adverse effect on children's health outcomes than experiencing household food insecurity for a shorter duration.ObjectivesExamine how changing household food security status and prolonged exposure to household marginal food security or food insecurity are associated with changes in children's growth from age 5 to 12.MethodsWe analyzed 204 mother‐child dyads from the Center for Health Assessment of Mothers and Children of Salinas (CHAMACOS), a longitudinal birth cohort study of Latino households. Generalized estimating equations assessed how changing household food security status and persistent exposure to marginal food security or food insecurity were associated with growth throughout childhood.ResultsLiving in a marginally food secure of food insecure household compared to highly food secure household was associated with a decrease in BMI z‐score of 0.18 (0.09, 0.26) between age 9 and 10.5. Changing from a highly food secure household to a marginally food secure or food insecure household was associated with a 0.10 (0.01, 0.20) decrease in body mass index z‐score compared to those who persistently lived in highly food secure households.ConclusionsChanges in food security status and duration of food insecurity were associated with changes in children's growth.

AbstractThe COVID‐19 pandemic has had an important impact on the academic world. It is known that university studies can influence the mental health of students, and especially those studying health sciences. In this study, we therefore sought to analyse whether the current pandemic has affected the mental well‐being of final‐year nursing students. This was a multi‐centre study, with a descriptive, longitudinal, and prospective design. Mental well‐being was evaluated using the General Health Questionnaire. A total of 305 participants were included in the study, of whom 52.1% had experienced the COVID‐19 pandemic. Statistically significant differences were found between the two groups analysed in terms of age, access to university, average marks, mental well‐being self‐esteem, emotional exhaustion, and sense of coherence. In the case of mental well‐being, a direct association was found with both the pandemic situation (OR = 2.32, P = 0.010) and emotional exhaustion scores (OR = 1.20, P < 0.001), while an inverse association was found with sense of coherence scores (OR = 0.45, P < 0.001). This study shows that the mental health of students is a significant factor and one that must be taken into consideration when training nursing staff at university. There is a need to promote healthy habits and provide appropriate coping strategies. It is also important to train and prepare students for pandemic situations as these can have an important impact on the mental health of both the members of the public who will be treated by these future nursing professionals and the students themselves.
Love cannot buy you money: Resource exchange on reward‐based crowdfunding platforms

Published: January 2021

AbstractReward‐based crowdfunding platforms – in which campaigns exchange rewards for financial backing to develop a product or service – are one of the fastest‐growing segments of the crowdfunding industry. We use an extension of social exchange theory (SET) called the resource theory of social exchange (RTSE) to examine resource exchanges through rewards on Kickstarter. A resource exchange occurs when a project backer and project creator exchange money (ie, financial backing) for a reward (eg, a thank you or a t‐shirt). A project creator can develop a reward portfolio that contains various types of resources, which in the RTSE are categorised as love, status, information, money, goods and services. Our study provides a comprehensive examination of resource exchange on a major reward‐based crowd funding platform, answering the call to investigate the effects of a key element of such platforms – rewards. We find that the types of resources project creators include in the reward portfolios they offer should be carefully considered. Specifically, our results indicate it is more beneficial to offer rewards that contain universal and concrete resources (eg, goods, services) than resources that are particularistic and symbolic (eg, love, status). However, the positive effect of offering universal and concrete resources as rewards is diminished as the fundraising goal is increased, which suggests that the optimal design of the reward portfolio is contingent on other characteristics of the campaign. Moreover, our findings reveal that while it is advantageous to offer more rewards, it is disadvantageous to offer too many different types of resources across those rewards. Overall, our study adds depth to the understanding of resource exchange in reward‐based crowdfunding and provides practical insight into how to design reward portfolios.
Visual Instruction to Enhance Teaching of Technical Subject to Design Students

Published: January 2021

AbstractVisual instruction complementing verbal lectures is known to promote learning among students. In this study, the role of visual instruction in engaging learners effectively via the simplification of technical concepts was examined. Different aspects of visualisation, such as order of presenting and dimensionality, were tested to observe their effect on students’ approach to learning and learning outcomes. In this mixed‐method quasi‐non‐experimental explanatory study, visual instruction was applied in one of the undergraduate architecture modules that teaches fundamentals of building systems, which students often find difficult to comprehend. Three key variables, including spatial cognitive ability, approach to learning and learning outcomes, were measured using statistically valid instruments along with students’ feedback and interviews. These factors were also measured for the control group that did not receive visual instruction (n = 32), to assess the effect of the intervention. When taught with visualisation, students (n = 69), showed a significant increase in deep approach to learning (e.g., deep motive: t = 2.584, p = 0.011). In interviews, students expressed a deeper interest in the subject and reported that the topic was engaging in class. Visualisation favours students with a higher spatial ability and, thus, is useful for design students who receive spatial ability training in the course. Two‐dimensional visuals must be followed and preceded by three‐dimensional visuals to provide advanced organisation and the connection of new knowledge with known organisational models to be made.

AbstractThis study aimed to compare perspective‐taking with a hypothetical target and perspective‐taking occurring during a real interaction with an outgroup member in reducing prejudice toward people with disabilities and other groups (e.g., immigrants, homosexual people), via increased empathy. We adopted an experimental design with two treatment groups (Hypothetical target vs. Real target) and one control group (no intervention), one pretest and two posttest measures. Participants, who were 437 students aged 11–17 years (M = 14.28; SD = 1.17), were randomly assigned to the various conditions on a classroom basis. Perspective‐taking was facilitated asking participants to travel in a wheelchair on a path that simulated a real pavement in the presence (or not) of an individual with a motor disability. Findings showed that perspective‐taking in the presence of a real target was more effective in reducing prejudice toward people with disabilities than perspective‐taking task without encountering an outgroup member. Perspective‐taking with a hypothetical target was not sufficient to increase participants' empathy toward people with disabilities, which instead was enhanced when the task was performed at the presence of a real member of that group. Positive effects produced by perspective‐taking (with both a hypothetical and a real target) were transferred to immigrants and homosexuals. These findings suggest that, when possible, perspective‐taking in the presence of the target, which can improve empathy by favoring a two‐way exchange process, is highly recommended to improve attitudes toward different stigmatized groups, not necessarily targeted by the intervention.
Multiple potential roles of thymosin β4 in the growth and development of hair follicles
Authors: Dai Bai , Sha Ri‐Na , Yuan Jian‐Long , Liu Dong‐Jun 
Published: January 2021

AbstractThe hair follicle (HF) is an important mini‐organ of the skin, composed of many types of cells. Dermal papilla cells are important signalling components that guide the proliferation, upward migration and differentiation of HF stem cell progenitor cells to form other types of HF cells. Thymosin β4 (Tβ4), a major actin‐sequestering protein, is involved in various cellular responses and has recently been shown to play key roles in HF growth and development. Endogenous Tβ4 can activate the mouse HF cycle transition and affect HF growth and development by promoting the migration and differentiation of HF stem cells and their progeny. In addition, exogenous Tβ4 increases the rate of hair growth in mice and promotes cashmere production by increasing the number of secondary HFs (hair follicles) in cashmere goats. However, the molecular mechanisms through which Tβ4 promotes HF growth and development have rarely been reported. Herein, we review the functions and mechanisms of Tβ4 in HF growth and development and describe the endogenous and exogenous actions of Tβ4 in HFs to provide insights into the roles of Tβ4 in HF growth and development.
