description: Silver nanoparticles were synthesized through an eco-friendly process using an extract of Zingiber officinale rhizome. Spectrophotometric analysis of the AgNPs exhibited sharp band centered around 400–420 nm. The functionality of phytochemicals present in the Z. officinale was identified using FTIR spectroscopy. The characterization of synthesized AgNPs was done by UV-Vis spectroscopy, transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), and selected area electron diffraction pattern (SAED), particle size, and zeta potential analyzer. The average measured size and diameter of AgNPs were ∼20 nm, measured by XRD and TEM. We have successfully utilized the AgNPs as efficient catalyst in degradation of harmful dyes: methylene blue, methyl red, and safranin O. The rate constant for the degradation of dyes was found to be 14.25 × 10−3 sec−1, 9.68 × 10−3 sec−1 and 4.72 × 10−3sec−1 for methylene blue, methyl red, and safranin O respectively.

description: Understanding how to use generative AI can greatly benefit the learning process. Despite available concepts for teaching “how to prompt”, little empirical evidence exists on students’ current micro-level chatbot use that would justify a need for instruction on how to prompt. This pilot study investigates students’ chatbot use in an authentic setting. Findings reveal general interaction patterns, including a notable lack of conversational patterns, indicating an underutilization of this central chatbot capability. However, despite having no formal instruction, some students discovered specific chatbot affordances. While basic prompting skills are displayed or acquired during exploration, explicit training on effective chatbot interaction could enhance skillful chatbot use. This training should integrate cognitive and metacognitive strategies as well as technological knowledge, helping students leverage the technology’s full potential.

description: Finite temperature quantum field theory in the heat kernel method is used to study the heat capacity of condensed matter. The lattice heat is treated a la P. Debye as energy of the elastic (sound) waves. The dimensionless functional of free energy is re-derived with a cut-off parameter and used to obtain the specific heat of crystal lattices. The new dimensionless thermodynamical variable is formed as the Planck's inverse temperature divided by the lattice constant. The dimensionless constant, universal for a class of crystal lattices, which determines the low temperature region of molar specific heat, is introduced and tested with the data for diamond lattice crystals. The low temperature asymptotics of specific heat is found to be the fourth power in temperature instead of the cubic power law of the Debye theory. Experimental data for the carbon group elements (silicon, germanium) and other materials decisively confirm the quartic law. The true low temperature regime of specific heat is defined by the surface heat, therefore, it depends on geometrical characteristics of a body, while the absolute zero temperature limit is geometrically forbidden. The limit on a growth of specific heat at temperatures close to critical points, known as the Dulong-Petit law, appears from the lattice constant cut-off. Its value depends on the lattice type and it is the same for materials with the same crystal lattice. The Dulong-Petit values of compounds are equal to those of elements with the same crystal lattice type, if one mole of solid state matter were taken as the Avogadro number of the lattice atoms. This means the Neumann-Kopp rule is valid only in some cases.

description: "Sustainably produced" food labels have rapidly grown in popularity over the past decade (Batte 2011). Moreover, because there is no government agency overseeing certification of these production methods, consumers are generally confused about the production attributes that may or may not be present in a sustainable food system. This paper analyzes data from a hypothetical choice experiment to better understand consumer purchasing behavior when faced with competing food production attributes such as "organic" and "local". We seek to estimate preferences for "sustainably produced" food products and determine how they may be affected by varying degrees of information about sustainable agricultural systems. Additionally, the willingness to pay measurements estimated in this paper provide insight into the trade-offs perceived between current eco-labeling schemes, and the potential for differentiating "sustainably produced" products from their "organic" and "local" counterparts.

description: A new basis of states for highest-weight modules in $\ZZ_k$ parafermionic conformal theories is displayed. It is formulated in terms of an effective exclusion principle constraining strings of $k$ fundamental parafermionic modes. The states of a module are then built by a simple filling process, with no singular-vector subtractions. That results in fermionic-sum representations of the characters, which are exactly the Lepowsky-Primc expressions. We also stress that the underlying combinatorics -- which is the one pertaining to the Andrews-Gordon identities -- has a remarkably natural parafermionic interpretation.

description: This article estimates the demand for mint-flavored gum products using grocery store sales data and accounting for consumers’ valuation of quality. Unobserved product attributes, such as flavor quality, are important elements to consider when estimating the demand for gum. The estimation results suggest that gum is an inelastic product. A positive relationship between willingness to pay and unobserved quality was identified, implying that gum industry should be able to command a premium for higher quality mint flavored products.

description: Following recent work by van der Hoeven and Lecerf (ISSAC 2017), we discuss the complexity of linear mappings, called untangling and tangling by those authors, that arise in the context of computations with univariate polynomials. We give a slightly faster tangling algorithm and discuss new applications of these techniques. We show how to extend these ideas to bivariate settings, and use them to give bounds on the arithmetic complexity of certain algebras.

description: Ventricular fibrillation, the major reason behind sudden cardiac death, is turbulent cardiac electrical activity in which rapid, irregular disturbances in the spatiotemporal electrical activation of the heart makes it incapable of any concerted pumping action. Methods of controlling ventricular fibrillation include electrical defibrillation as well as injected medication. Electrical defibrillation, though widely used, involves subjecting the whole heart to massive, and often counterproductive, electrical shocks. We propose a defibrillation method that uses a very-low-amplitude shock (of order mV) applied for a brief duration (of order 100 ms) and over a coarse mesh of lines on our model ventricle.

description: Surfaces of surfactant-templated polyacrylamide hydrogels were imaged by atomic force microscopy (AFM), and the surface morphology was studied by numerical scaling analysis. The templated gels were formed by polymerizing acrylamide plus a cross-linker in the presence of surfactants, which were then removed by soaking in distilled water. Gels formed in the presence of over 20% surfactant (by weight) formed clear, but became opaque upon removal of the surfactants. Untemplated gels formed and remained clear. The surface morphology of the gels was studied by several one- and two-dimensional numerical scaling methods. The surfaces were found to be self-affine on short length scales, with a roughness (Hurst) exponent in the range 0.85 to 1, crossing over to a constant root-mean-square surface width on long scales. Both the crossover length between these two regimes and the saturation value of the surface width increased significantly with increasing surfactant concentration, coincident with the increase in opacity. We propose that the changes in the surface morphology are due to a percolation transition in the system of voids formed upon removal of the surfactants from the bulk.

description: Public policy discussion of the problem of food deserts has concentrated on proximity to retail food stores providing nutritious, affordable foods. Because they offer a wide array of healthful products at lower prices, physical access to a supermarket or supercenter has come to be the standard of adequacy. Less attention has been given to how economic incentives influence access to retail food stores in the wider food environment. The American Recovery and Reinvestment Act (ARRA) enacted a sizable increase in SNAP benefits effective April 2009. Though the primary purpose of the increase was to stimulate the economy, we argue that it had a secondary effect of encouraging SNAP participants to redeem more of their benefits at larger, lower-priced retailers. To investigate the effect of this policy change, we use county-level, administrative data on SNAP redemptions at different types of authorized food stores from May 2007 to May 2010. Data from the Economic Research Service’s Food Desert Locator are used to classify counties according to the percent of their population residing in food deserts. Results show that the SNAP benefit increase is associated with a greater percentage of redemptions at superstores. Estimates are stable across a number of specifications that also control for gas prices and store-type density. Within our sample of counties, we show that an $80 maximum SNAP benefit increased the percentage of benefits redeemed at supermarkets by 1.4 percentage points. In order to achieve a similar increase in redemptions at superstores, store density would have to increase from one superstore every 24 square miles to 1 superstore every 15 square miles. Impacts of the benefit increase were positive, but somewhat smaller in areas with more of their population residing in food deserts.

description: While critical thinking may be difficult to define, development of critical thinking skills is a principle goal of education, particularly higher education. It is vital that college graduates can question assumptions, synthesize information, evaluate evidence, draw inferences, and make reasoned arguments. Critical thinking skills do not improve without practice; effective teaching methods engage students with course material and each other, challenging them to think through issues and problems relevant to the real world. Engagement or problem solving alone, however, does not guarantee improved critical thinking. This study evaluates the impact of one alternative teaching method, team-based learning, on students’ perceptions of the development of critical thinking skills.

description: There is an increasing shift in technology towards biometric solutions, but one of the biggest barriers to widespread use is the acceptance by the users. In this paper we investigate the understanding, awareness and acceptance of biometrics by the general public. The primary research method was a survey, which had 282 respondents, designed to gauge public opinion around biometrics. Additionally, qualitative data was captured in the form of the participants' definition of the term \textit{biometrics}. We applied thematic analysis as well as an automated Word Vector analysis to this data to provide a deeper insight into the perceptions and understanding of the term. Our results demonstrate that while there is generally a reasonable level of understanding of what biometrics are, this is typically limited to the techniques that are most familiar to participants (e.g., fingerprints or facial recognition). Most notably individuals' awareness overlooks emerging areas such as behavioural biometrics (e.g., gait). This was also apparent when we compared participants' views to definitions provided by official, published sources (e.g., ISO, NIST, OED, DHS). Overall, this article provides unique insight into the perceptions and understanding of biometrics as well as areas where users may lack knowledge on biometric applications.

description: Consumption of food away from home (FAFH) is widely believed to be a contributing factor to the current obesity crisis and other diet related problems in North America. Although FAFH expenditure represents a lower proportion of food expenditure in Canada than in the United States (24% versus 50%) it is still a significant part of Canadian diets. The Canadian Heart and Stroke Foundation has developed a third party accreditation program to identify healthy food items in grocery stores and more recently, restaurants, called the Health Check™ program. The program is not without controversy since some people feel that it is inappropriate to pay for the use of the label and it may be misleading that many processors and restaurants choose not to apply for their food products resulting, in some cases, that healthier foods without such a label may be next to other products with labels on shelves or on menus. For such a diet indicator to be helpful in enhancing public health the label must be used by people who have health problems and buy the food products labeled. The objective of this research is to examine the possible impact of the Health Check™ program for a particular group of Canadian FAFH consumers. Through the use of the NPD Group CREST® data over the period February 2007 to February 2009, actual restaurant purchases for a representative panel of Canadians were identified. In August 2009 a survey of 3319 of those same panelists was conducted. As part of the survey, respondents were asked for stated preferences for a turkey sandwich with various different nutrition labels and the Health Check™. The results suggest that there is on average a positive WTP for the provision of additional nutritional information associated with turkey sandwiches and for the Health Check™. The results highlight the importance of providing fat content information, in terms of attracting the attention of the survey respondents to the nutrient content. There is little link between survey respondents level of historical diet quality and their willingness to pay for the Health Check™ information in their sandwich purchases; unfortunately this suggests that the Health Check™ might not have its biggest impact on those that need it the most. For those with the highest historical diet quality the provision of nutrient information and/or the Health Check™ has little appeal, perhaps reflecting their higher existing nutritional engagement – do they actually need more information?

description: Ways of increasing the market for local produce beyond the local residents within the local community, could include the following two potential solutions: 1) an expansion out to a more national/global market, which though would be costly in terms of transportation costs or 2) getting national/global consumers into the local market, e.g. as tourists. The objective of the present paper is to investigate the tourism's potential in the promotion of locally produced food products, within the perspective of context dependency and consumers' preferences for local produce. Firstly, people are asked to state their preferences for locally produced apples and honey, respectively. Secondly, we illustrate how preferences towards local produce depend on the situation, in which the consumers are placed. Applying a CE we find that for honey, the consumers' willingness to pay for local produce displays a considerable variation across respondents, suggesting that there could be a potential segmentation of respondents and their willingness to pay, which could imply the market to be highly niched. This is further investigated by applying a discrete mixture model. The findings from the DM model suggests that the market for the two characteristics local and Danish produce in both honey and apples and within both a daily and a holiday context is segmented into two groups - one group (2/3) who do not have particular high preferences towards neither Danish nor local produce and another group (1/3), who do have rather large preferences for both characteristics.
Exploration of self-assembled carbon nanomaterials through various dimensions

description: The realm of the carbon nanomaterials (CNMs) runs extremely deep and spans many members: nanotubes (CNTs), graphene, buckminsterfullerenes, carbon dots, graphene oxide (GO), nanodiamond, nanoribbons, carbon fibre, nano-onions, peapods, nanobuds, and new members graphyne and fullertubes, with nanotubes, buckminsterfullerenes, and graphene being the most famous of CNM family. They have a plethora of applications ranging from bioimaging to display technology to sensors. In this thesis, we filled carbon nanotubes with fullerenes and metallofullerenes (Lu and Gd) and obtained visual confirmation of this via high resolution scanning transmission electron microscopy. Additionally, we obtained baseline Raman measurements. These filled carbon nanotubes, which are called peapods, were made dispersible in water via a reaction with potassium metal. Then, more measurements via AFM, STEM, Raman, UV-Vis, and others were to help understand and confirm the dispersibility of the peapods. As a wrap-up, we did magnetic resonance imaging (MRI) to test the performance of the water dispersible Gd filled peapods and compared it to OmniscanTM. Here, it proved to have about 6x the contrast ability over OmniscanTM. Also, I functionalized C60 with complementary H-bonding ligands for self-assembly and attempted to covalently link C60 to the surface exfoliated graphite. Then, we move to a summary of fullerene formation, collaborative works involving XPS/STEM/EELS, and miscellaneous projects that did not pan out to wrap it all up.

description: A model of the passive vector quantity advected by a Gaussian time-decorrelated self-similar velocity field is studied; the effects of pressure and large-scale anisotropy are discussed. The inertial-range behavior of the pair correlation function is described by an infinite family of scaling exponents, which satisfy exact transcendental equations derived explicitly in d dimensions. The exponents are organized in a hierarchical order according to their degree of anisotropy, with the spectrum unbounded from above and the leading exponent coming from the isotropic sector. For the higher-order structure functions, the anomalous scaling behavior is a consequence of the existence in the corresponding operator product expansions of ``dangerous'' composite operators, whose negative critical dimensions determine the exponents. A close formal resemblance of the model with the stirred NS equation reveals itself in the mixing of operators. Using the RG, the anomalous exponents are calculated in the one-loop approximation for the even structure functions up to the twelfth order.

description: We report a simple technique for the selective etching of bilayer and monolayer MoS$_2$. In this work, chosen regions of MoS$_2$ were activated for oxygen adsorption and reaction by the application of low doses of He$^+$ at 30 keV in a gas ion microscope. Raman spectroscopy, optical microscopy and scanning electron microscopy were used to characterize both the etched features and the remaining material. It has been found that by using a pre-treatment to introduce defects, MoS$_2$ can be etched very efficiently and with high region specificity by heating in air.

description: The United Kingdom (UK) has one of the highest obesity levels in the world (Mazzocchi et al., 2009). As indicated by the National Health Service (2010), 25% of adults and 17% of children are obese in the UK. This last statistic represents an increase of four points in comparison to 1995. The Government Office for Science (2010) estimated that by 2050, half of the UK population would be obese, with a consequent direct annual cost of £10 billion and an indirect annual cost of £50 billion at today’s prices. This research aims to contribute to the debate on how health-related information impacts household food expenditure and whether this impact varies across income groups and household composition. This study specifically measures the impact of child obesity news on household food expenditure in the UK. To this end, the study calculated a set of elasticities for different income groups (high vs. low) and family composition (families with and without children). This set of elasticities gives us a measure of responsiveness, to change in terms of price, income and news. The results indicate that child obesity news causes different impacts on households according to their income level and household composition. Low-income households without children are not significantly impacted by child obesity news. Low-income households with children change their food expenditure composition to a healthier diet without changing the overall food expenditure. High-income households without children decrease their overall food expenditure, mainly changing red meat for dairy products. Finally, high-income households with children increase their overall food expenditure and move on to a healthier diet. Therefore, in three out of four household cases, child obesity news causes a different and positive impact on diet. Low-income households with children in default-mode spend the smallest proportion of their income on fruit and vegetables; which is even less than low-income households without children. More importantly, low-income households with children influence the nutritional habits of their children. This research shows that low-income households with children respond to child obesity news and move on to a healthier diet without causing undesirable income redistribution.

description: It was recently shown (Keating & Prado, {\it Proc. R. Soc. Lond. A} {\bf 457}, 1855-1872 (2001)) that, in the semiclassical limit, the scarring of quantum eigenfunctions by classical periodic orbits in chaotic systems may be dramatically enhanced when the orbits in question undergo bifurcation. Specifically, a bifurcating orbit gives rise to a scar with an amplitude that scales as $\hbar^α$ and a width that scales as $\hbar^ω$, where $α$ and $ω$ are bifurcation-dependent scar exponents whose values are typically smaller than those ($α=ω=1/2$) associated with isolated and unstable periodic orbits. We here analyze the influence of bifurcations on the autocorrelation function of quantum eigenstates, averaged with respect to energy. It is shown that the length-scale of the correlations around a bifurcating orbit scales semiclassically as $\hbar^{1-α}$, where $α$ is the corresponding scar amplitude exponent. This imprint of bifurcations on quantum autocorrelations is illustrated by numerical computations for a family of perturbed cat maps.

description: Background. Refactoring is a critical task in software maintenance and is generally performed to enforce the best design and implementation practices or to cope with design defects. Several studies attempted to detect refactoring activities through mining software repositories allowing to collect, analyze and get actionable data-driven insights about refactoring practices within software projects. Aim. We aim at identifying, among the various quality models presented in the literature, the ones that are more in-line with the developer's vision of quality optimization, when they explicitly mention that they are refactoring to improve them. Method. We extract a large corpus of design-related refactoring activities that are applied and documented by developers during their daily changes from 3,795 curated open source Java projects. In particular, we extract a large-scale corpus of structural metrics and anti-pattern enhancement changes, from which we identify 1,245 quality improvement commits with their corresponding refactoring operations, as perceived by software engineers. Thereafter, we empirically analyze the impact of these refactoring operations on a set of common state-of-the-art design quality metrics. Results. The statistical analysis of the obtained results shows that (i) a few state-of-the-art metrics are more popular than others; and (ii) some metrics are being more emphasized than others. Conclusions. We verify that there are a variety of structural metrics that can represent the internal quality attributes with different degrees of improvement and degradation of software quality. Most of the metrics that are mapped to the main quality attributes do capture developer intentions of quality improvement reported in the commit messages.

description: We extend a previously proposed deposition model with two kinds of particles, considering the restricted solid-on-solid condition. The probability of incidence of particle C (A) is p (1-p). Aggregation is possible if the top of the column of incidence has a nearest neighbor A and if the difference in the heights of neighboring columns does not exceed 1. For any value of p>0, the deposit attains some static configuration, in which no deposition attempt is accepted. In 1+1 dimensions, the interface width has a limiting value W_s ~ p^{-η}, with η= 3/2, which is confirmed by numerical simulations. The dynamic scaling relation W_s = p^{-η} f(tp^z) is obtained in very large substrates, with z=η.

description: This paper analyses how individuals trade-off health risks against lifestyle choices. The work uses a choice experiment (CE) survey for a representative sample of the Northern Ireland population. Unlike most CE studies for valuing public health programs, this questionnaire uses a tailored exercise based on the individuals’ baseline choices. A fat screener links actual cardiovascular diseases (CVD) risk to each specific choice set in terms of diet. Individuals are informed about their real status quo risk of a fatal cardiovascular event, based on an initial set of health questions. Thus, actual risks, real diet and exercise choices are the elements that constitute the choice task. Our results show that our respondents are willing to pay for reducing mortality risk and, more importantly, are willing to change physical exercise and dietary behaviours. In particular, subjects with Body Mass Index (BMI) in the range of overweight or obese seem more inclined to practise physical exercise than to modify their diet to reduce their CVD risks.

description: The 2008 Farm Act introduced a wholly new type of commodity program intended to protect producers against price and yield variability through a market-oriented revenue guarantee. Expectations were high in 2009 that many producers would choose the new Alternative Crop Revenue Election (ACRE) program, but that did not happen. We analyze this unexpected outcome by using newly available farm-level administrative data to examine a range of characteristics of individual farms and multi-farm operations that enrolled and did not enroll in ACRE. We both confirm some previous survey and county-level findings and identify some additional characteristics associated with the decision. Using a logit model, we examine the probability that non-enrollment might be linked to the number of stakeholders on a farm, since enrollment required unanimous agreement. Unexpectedly, we find that the number of signatories on a base contract did not seem to affect the ACRE decision; if anything, there was a very slight probability that increasing the number of signatories might positively affect the ACRE decision. We also find that on multi-farm operations with some ACRE enrollment, those farms not enrolled in ACRE are distinctly different from the ACRE-enrolled farms and average farms in their regions, a finding we believe warrants additional investigation.

description: Through a geographically weighted panel regression analysis, we demonstrate the spatially varying relationship between weather and corn yields. A balanced panel data of 958 U.S. corn production counties for the period 2002-2006 is used. The results indicate that the relationship between weather and corn yield has large spatial variability. In specific, temperature tends to have negative marginal effects on corn yield in warmer regions, and positive effects in cooler regions. The spatial pattern of precipitation effects is more complicated since it is expected to be largely affected by local irrigation systems.
