Fast acquisition of extensive X-ray diffraction patterns of a gas–liquid interface in grazing-incidence geometry

The development of third-generation synchrotron sources has inspired qualitative and quantitative breakthroughs in structural studies of monomol­ecular organic layers. To study such systems formed at the gas–liquid interface, grazing-incidence diffraction (GID) has proved to be the most powerful technique. Until quite recently, in most cases, GID was performed via a scanning approach with use of a collimating system in front of the detector to eliminate the effect of parallax and to achieve the required angular resolution. Owing to the long counting time required, this kind of measurement often introduces significant radiation damage to a sample and considerably restricts time-resolved studies, preventing the pursuit of emerging scientific areas such as the investigation of fast kinetic structural changes in two-dimensional systems. This problem can apparently become a real obstacle for the application of the scanning GID technique at fourth-generation synchrotron sources because of the extremely high X-ray fluxes involved. This article discusses the possibility of significantly reducing the measuring time and avoiding the beam parallax problem by using a high-brilliance submillimetre beam and a large-area two-dimensional detector (e.g. PILATUS) in a single-shot GID measurement on large-area sample surfaces. Both theoretical considerations of the problem and experimental GID results from monomolecular layers of behenic acid at the gas–water interface are presented, with a detailed description of the experimental conditions. The possibility of a diffraction imaging study of the texture of Langmuir monomolecular layers is demonstrated.
Relationship between physicochemical and cooking properties, and effects of cooking on antinutrients, of yellow field peas (Pisum sativum)

The relationship between the physicochemical and cooking properties of yellow peas was examined in this study. A positive correlation was found between seed weight and water hydration capacity. The Peleg model, which was modified, could be used to describe the water absorption characteristics of peas and could be used to predict the rate of water absorption in the initial water absorption period. Cooking time could be measured objectively using the Mattson cooker. Cooking time was found to decrease with an increase in water hydration capacity. Hardness of cooked peas, measured using a texture analyser, was negatively correlated with both seed weight and water hydration capacity. Seed coats had a significant effect on water hydration and cooking quality of peas. Peas with relatively thin seed coats exhibited higher water hydration capacity, shorter cooking times and softer texture after cooking. The effects of soaking and cooking on trypsin inhibitor activity (TIA) and oligosaccharide levels in peas were also studied. Cooking was more effective than soaking in reducing TIA levels and oligosaccharides (raffinose, stachyose and verbascose) in peas. Copyright © 2003 Society of Chemical Industry
Input Test Signal Design and Parameter Estimation Method for the Hammerstein-Wiener Processes

We propose a new parameter estimation method for Hammerstein-Wiener-type processes composed of the input-output nonlinear static functions and a linear dynamic subsystem. A special test signal is designed to separate the identification problems of the linear dynamic subsystem and the output nonlinear static function from that of the input nonlinear static function. Then, the system identification procedure can be significantly simplified: the identification problems of the linear dynamic subsystem and the output nonlinear static function can be solved independently without considering the input nonlinear static function, and the model parameters of the input nonlinear static function can also be estimated analytically without any iterative nonlinear optimization. Furthermore, we develop a new estimation algorithm to identify the linear dynamic subsystem and the output nonlinear static function more efficiently. This algorithm does not need to initialize the model parameters of the output nonlinear static function and reduces the searching space in the iterative nonlinear optimization problem, resulting in more robust and faster convergence and easier initialization in the nonlinear optimization compared to previous approaches.
Dynamic Modeling of Non‐equilibrium Latex Particle Morphology Development During Seeded Emulsion Polymerization

We have developed software to simulate the development of non‐equilibrium latex particle morphologies produced by seeded emulsion polymerization. The diffusion of second stage polymer radicals within seed particles controls the development of morphology in a large number of systems. Knowledge of the conditions present within the latex particles during the reaction is required in order to model this diffusion process, and this makes it necessary to first simulate the kinetics of the polymerization. The program considers both the water phase and particle phase reactions, and can simulate polymerizations carried out under either batch or semi‐batch conditions. The model predictions agree well with experimental results both in terms of the polymerization kinetics and the development of particle morphology.
Enhanced IL-36R signaling promotes barrier impairment and inflammation in skin and intestine

Unrestrained IL-36R signaling in a humanized mouse model causes barrier impairment and increased cutaneous and intestinal inflammation. Sequelae of unrestrained IL-36 signaling The IL-36 receptor integrates signals from three proinflammatory IL-36 agonist ligands opposed by one natural antagonist (IL-36Ra). Hovhannisyan et al. developed mice humanized for the extracellular portion of IL-36R and the IL-36 agonists (α, β, and γ) to evaluate anti-inflammatory treatment using antibodies blocking the human IL-36R. The mouse version of IL-36Ra retained by these mice is a weaker inhibitor at the human IL-36R than its human counterpart, leaving these mice susceptible to enhanced skin and intestinal inflammation after epithelial barrier insults. Antibodies blocking the IL-36R or the shared p40 subunit of IL-12/IL-23 interrupted an overlapping set of proinflammatory circuits in these mice, indicating that IL-36R–targeting therapeutics are candidates to treat some of the same human diseases responsive to inhibition of the IL-23/IL-17 axis. Deficiency in interleukin-36R (IL-36R) antagonist caused by loss-of-function mutations in IL-36RN leads to DITRA (deficiency of IL-36 receptor antagonist), a rare inflammatory human disease that belongs to a subgroup of generalized pustular psoriasis (GPP). We report a functional genetic mouse model of DITRA with enhanced IL-36R signaling analogous to that observed in patients with DITRA, which provides new insight into our understanding of the IL-36 family of molecules in regulating barrier integrity across multiple tissues. Humanized DITRA-like mice displayed increased skin inflammation in a preclinical model of psoriasis, and in vivo blockade of IL-36R pathway using anti-human IL-36R antibody ameliorated imiquimod-induced skin pathology as both prophylactic and therapeutic treatments. Deeper characterization of the humanized DITRA-like mice revealed that deregulated IL-36R signaling promoted tissue pathology during intestinal injury and led to impairment in mucosal restoration in the repair phase of chronic dextran sulfate sodium (DSS)–induced colitis. Blockade of IL-36R pathway significantly ameliorated DSS-induced intestinal inflammation and rescued the inability of DITRA-like mice to recover from mucosal damage in vivo. Our results indicate a central role for IL-36 in regulating proinflammatory responses in the skin and epithelial barrier function in the intestine, suggesting a new therapeutic potential for targeting the IL-36R axis in psoriasis and at the later stages of intestinal pathology in inflammatory bowel disease.
Code-Switching as a Strategy in Conducting Public Affairs: A Case Study of Rural Namibians

Outapi is a rural town in the northern part of Namibia. Its residents are exposed to a variety of languages. Speakers whose English proficiency is limited, but who are able to communicate in Oshiwambo, use Oshiwambo to communicate. The problem arises when communication is in English, as the majority are English second or third language speakers and thus unable to express themselves very well. This study sought to understand the role of code switching between English and Oshiwambo by Outapi residents and public officials when conducting public affairs in the bank, the clinic and the post office. A qualitative research approach based on a case study research design was applied to determine the pertinence of code switching in the multilingual community. Findings from observations and interviews revealed that code switching facilitated communication in Outapi for speakers to attain their communication goals. Although the study indicated how code switching enriches Oshiwambo in terms of vocabulary, it also indicates a contribution to the language death of local languages.
Mobile Mood Tracking

Commonly used mood measures are either lengthy or too complicated for repeated use. Mood tracking research is, therefore, associated with challenges such as user dissatisfaction, fatigue, or dropouts from studies. Previous efforts to improve user experience are mostly ambiguous concerning their validity and the extent of improvement they provide (e.g., compared to established measures, such as PANAS). This paper investigates the shortening of a self-reported mood measure using smartphones with four independent samples, and provides a baseline for comparing the usability and accuracy of future measures. It first examines whether user self-assessment of overall positive and negative activations with a two-item measure can capture mood as well as I-PANAS-SF. It next examines user's learning effect in repeated usage of the measure. Finally, it introduces the design of an adaptive mood measure that reduces the number of questions based on its prediction of user mood fluctuations. This adaptive measure can potentially capture specific mood states, as well as overall mood. The paper then explores user satisfaction and compliance with this measure in a longitudinal study. The results of this paper reveal that the investigated two-item measure is a valid and reliable tool for capturing a user's overall mood and mood fluctuations. The negative activation from this measure is associated with stress. Our results suggest that the association between mood and stress generally depends on the measure of mood and its items. We discovered that a non-complex self-explanatory measure is fairly resilient for repeated use with respect to the required effort and the accuracy of the measure in both daily and weekly evaluations. Adaptively reducing the length of a mood measure does not seem to impact user compliance but may slightly improve usability. We also noticed that positive and negative activations have a slightly different pattern of behavior with reference to the preceding mood states.
Degeneration-Dependent Retinal Remodeling: Looking for the Molecular Trigger

Vision impairment and blindness in humans are most frequently caused by the degeneration and loss of photoreceptor cells in the outer retina, as is the case for age-related macular degeneration, retinitis pigmentosa, retinal detachment and many other diseases. While inner retinal neurons survive degeneration, they undergo fundamental pathophysiological changes, collectively known as “remodeling. ” Inner retinal remodeling downstream to photoreceptor death occurs across mammalian retinas from mice to humans, independently of the cause of degeneration. It results in pervasive spontaneous hyperactivity and membrane hyperpermeability in retinal ganglion cells, which funnel all retinal signals to the brain. Remodeling reduces light detection in vision-impaired patients and precludes meaningful vision restoration in blind individuals. In this review, we summarize current hypotheses proposed to explain remodeling and their potential medical significance highlighting the important role played by retinoic acid and its receptor.
Radiomics Approach for Prediction of Recurrence in Non-Functioning Pituitary Macroadenomas

Objectives A subset of non-functioning pituitary macroadenomas (NFPAs) may exhibit early progression/recurrence (P/R) after surgical resection. The purpose of this study was to apply radiomics in predicting P/R in NFPAs. Methods Only patients who had undergone preoperative MRI and postoperative MRI follow-ups for more than 1 year were included in this study. From September 2010 to December 2017, 50 eligible patients diagnosed with pathologically confirmed NFPAs were identified. Preoperative coronal T2WI and contrast-enhanced (CE) T1WI imaging were analyzed by computer algorithms. For each imaging sequence, 32 first-order features and 75 texture features were extracted. Support vector machine (SVM) classifier was utilized to evaluate the importance of extracted parameters, and the most significant three parameters were used to build the prediction model. The SVM score was calculated based on the three selected features. Results Twenty-eight patients exhibited P/R (28/50, 56%) after surgery. The median follow-up time was 38 months, and the median time to P/R was 20 months. Visual disturbance, hypopituitarism, extrasellar extension, compression of the third ventricle, large tumor height and volume, failed optic chiasmatic decompression, and high SVM score were more frequently encountered in the P/R group (p < 0.05). In multivariate Cox hazards analysis, symptoms of sex hormones, hypopituitarism, and SVM score were high risk factors for P/R (p < 0.05) with hazard ratios of 10.71, 2.68, and 6.88. The three selected radiomics features were T1 surface-to-volume radio, T1 GLCM-informational measure of correlation, and T2 NGTDM-coarseness. The radiomics predictive model shows 25 true positive, 16 true negative, 6 false positive, and 3 false negative cases, with an accuracy of 82% and AUC of 0.78 in differentiating P/R from non-P/R NFPAs. For SVM score, optimal cut-off value of 0.537 and AUC of 0.87 were obtained for differentiation of P/R. Higher SVM scores were associated with shorter progression-free survival (p < 0.001). Conclusions Our preliminary results showed that objective and quantitative MR radiomic features can be extracted from NFPAs. Pending more studies and evidence to support the findings, radiomics analysis of preoperative MRI may have the potential to offer valuable information in treatment planning for NFPAs.
Triple Disadvantage: Neighborhood Networks of Everyday Urban Mobility and Violence in U.S. Cities

This article develops and assesses the concept of triple neighborhood disadvantage. We argue that a neighborhood’s well-being depends not only on its own socioeconomic conditions but also on the conditions of neighborhoods its residents visit and are visited by, connections that form through networks of everyday urban mobility. We construct measures of mobility-based disadvantage using geocoded patterns of movement estimated from hundreds of millions of tweets sent by nearly 400,000 Twitter users over 18 months. Analyzing nearly 32,000 neighborhoods and 9,700 homicides in 37 of the largest U.S. cities, we show that neighborhood triple disadvantage independently predicts homicides, adjusting for traditional neighborhood correlates of violence, spatial proximity to disadvantage, prior homicides, and city fixed effects. Not only is triple disadvantage a stronger predictor than traditional measures, it accounts for a sizable portion of the association between residential neighborhood disadvantage and homicides. In turn, potential mechanisms such as neighborhood drug activity, interpersonal friction, and gun crime prevalence account for much of the association between triple disadvantage and homicides. These findings implicate structural mobility patterns as an important source of triple (dis)advantage for neighborhoods and have implications for a broad range of phenomena beyond crime, including community capacity, gentrification, transmission in a pandemic, and racial inequality.

Mobile Nationalism: Parenting and Articulations of Belonging among Globally Mobile Professionals

This article examines whether and how globally mobile middle-class professional families engage in practices of nationalism through forging connections with a ‘home nation’ despite continuous relocations for work. Drawing on the concept of boundary objects which are used to facilitate frequent boundary crossings, we identify the promotion of language acquisition and cultural or national rituals and traditions as two central family practices that maintain strong connections to a form of national belonging despite being physically de-territorialised. We coin the term ‘mobile nationalism’ to make sense of the ways these globally mobile professional parents cultivate a sense of identity, coherence and the necessary resources for future mobility. We argue that these articulations of nationalism continue to be critical as we seek to understand subjecthood formation in the face of the imperatives of globalisation.
Does Use of Emotion Increase Donations and Volunteers for Nonprofits?

Nonprofits offer services to disadvantaged populations, mobilize collective action, and advocate for civil rights. Conducting this work requires significant resources, raising the question: how do nonprofits succeed in increasing donations and volunteers amid widespread competition for these resources? Much research treats nonprofits as cold, rational entities, focusing on overhead, the “price” of donations, and efficiency in programming. We argue that nonprofits attract donors and volunteers by connecting to their emotions. We use newly available administrative IRS 990 e-filer data to analyze 90,000 nonprofit missions from 2012 to 2016. Computational text analysis measures the positive or negative affect of each nonprofit’s mission statement. We then link the positive and negative sentiment expressed by nonprofits to their donations and volunteers. We differentiate between the institutional fields of nonprofits—for example, arts, education, social welfare—distinguishing nonprofits focused on social bonding from those focused on social problems. We find that expressed positive emotion is often associated with higher donations and volunteers, especially in bonding fields. But for some types of nonprofits, combining positive sentiment with negative sentiment in a mission statement is most effective in producing volunteers. Auxiliary analyses using experimental and longitudinal designs provide converging evidence that emotional language enhances charitable behavior. Understanding the role of emotion can help nonprofit organizations attract and engage volunteers and donors.
Left Behind in the Hungarian Rustbelt: The Cultural Political Economy of Working-Class Neo-Nationalism

Nationalism is back with a renewed force. Hungary is a virulent example of the new nationalist ascendancy. As the country was a former liberal star pupil, Hungary’s neo-nationalist turn has been puzzling researchers for years. This study goes beyond the entrenched polarisations in the literature by highlighting the dynamic interplay between culture, structure and identity. It proposes to conceptualise Hungary’s neo-nationalist turn as a Polanyian countermovement against commodification, globalisation and deindustrialisation. The article presents the results of a thematic analysis of 82 interviews with workers in four towns in Hungary’s rustbelt and highlights how the multiscalar lived experience of commodifying reforms violated an implicit social contract and changed workers’ narrative identities. In the absence of a class-based shared narrative and lacking a viable political tool to control their fate, working-class neo-nationalism emerged as a new narrative identity to express workers’ anger and outrage.
Kalecki on Budget Deficits and the Possibilities for Full Employment

ABSTRACT This paper revisits the writings of Michal Kalecki which relate to issues of fiscal policy, budget deficits and securing full employment in capitalist economies. It seeks to relate those writings to the recent fiscal policy debates after the global financial crises. It covers the issues of the financing and funding of public expenditure and private expenditure. The relationship between the scale of budget deficit and the achievement of full employment is considered. Kalecki’s approach to the ‘burden’ of debt is elaborated. The social and political constraints on the achievement of full employment are revisited.
STUDIES ON POSTHARVEST PHYSIOLOGY AND THE STORAGE TECHNOLOGY OF MANGO (MANGIFERA INDICA L.)

Mango (Mangifera indica L. cv. Hongxiangya and Wacheng) was chosen to study the effect of postharvest biological characters in different storage conditions. The determining items included respiratory rate, total sugar, vitamin C (Vc) content, firmness, polyphenol oxidase (PPO) and peroxidase (POD). The results showed that both 8 and 11C were the better storage temperatures, and the storage life would last 50 days in this situation. The respiration rate increased quickly between the 16th to the 22nd days; the peak values were the 28th and 25th days at 8C for Hongxiangya and Wacheng, respectively. The flesh firmness decreased dramatically at 6 days after harvest. Total sugar content, Vc content, PPO and POD increased at first and then decreased. The color changed from green to yellow with the increase of carotenoids content. After treatment with thiabendozole and iprodione, the number of rot fruits was markedly lower than the other treatments. The best temperature is 11 and 14C for Hongxiangya and Wacheng, respectively. The rot rate is 6.77 and 8.33% with 1,000-ppm iprodine treatment after 50-days storage.
