Examining the Impacts of the Built Environment on Quality of Life in Cancer Patients Using Machine Learning

Despite accumulative evidence regarding the impact of the physical environment on health-related outcomes, very little is known about the relationships between built environment characteristics and the quality of life (QoL) of cancer patients. This study aims to investigate the association between the built environment and QoL by using survey data collected from cancer patients within the United States in 2019. To better understand the associations, we controlled the effects from sociodemographic attributes and health-related factors along with the residential built environment, including density, diversity, design, and distance to transit and hospitals on the self-reported QoL in cancer patients after treatment. Furthermore, machine learning models, i.e., logistic regression, decision tree, random forest, and multilayer perceptron neural network, were employed to evaluate the contribution of these features in predicting the QoL. The results from machine learning models indicated that the travel distance to the closest large hospital, perceived accessibility, distance to transit, and population density were among the most significant predictors of the cancer patients’ QoL. Additionally, the health insurance status, age, and education of patients are associated with QoL. The adverse effects of density on the self-reported QoL in this study can be addressed by individuals’ emotions towards negative aspects of density. Given the strong association between QoL and urban sustainability, consideration should be given to the side effects of urban density on cancer patients’ perceived wellbeing.
Children's stories of parental relationship breakdown and of their relationship with their non-resident parent

Britain has seen dramatic social changes to family life due to the growth of divorce and separation, producing burgeoning divorce literature. Surprisingly, relatively few studies have taken into account children’s views of their experiences. The present study investigated children’s stories of ‘parental relationship breakdown’ (PRB) and of their relationships with their non-resident parent. Twenty-seven children and their resident parent, were interviewed. Detailed qualitative analysis was conducted on the interviews of 18 children. The parent interview was structured to obtain background details of PRB, after which the parent completed a standardised measure of their child’s behaviour. The child interview was child-led. After the interview the children completed a standardised self-esteem measure. Narrative analysis provided a precis of the children’s stories in order to examine the main events they incorporated, and grounded theory was used to analyse the detail of the child’s experience. The majority of the children old enough to recall pre-PRB family life seemed to have an assumption about its permanency, the separation of the parents promoting doubts about their continued loveability and sense of being held in mind by the non-resident parent. Although children employed various strategies hypothesised as addressing these doubts, parents’ handling of the situation also appeared to play a major part in how the children made sense of their experiences and contained their anxieties. Tentative recommendations are that personal meanings of PRB for children (particularly regarding their perceived relationships with their parents) needs to be understood by both parents and clinicians in order to help children better contain feelings arising from the PRB. Families could benefit from more access to advice, support and information about the impending separation and events thereafter.
CFTR gating mechanism: The role of dimerization of nucleotide binding domains

The chloride channel, cystic fibrosis transmembrane conductance regulator (CFTR) has two membrane spanning domains (MSD), forming the channel pore, and two nucleotide binding domains (NBD), controlling the channel gating (opening and closing). The CFTR also has a unique regulatory (R) domain. After the CFTR is phosphorylated at R domain, gating of the phosphorylated CFTR is coupled to ATP binding and hydrolysis at CFTR’s two NBDs. However, the role of dimerization in channel gating is unknown. We first investigated whether two ATP binding sites play an equivalent role in the dynamics of NBD dimerization, therefore in gating CFTR channels. By identifying two critical aromatic amino acids that coordinate the adenine ring of the bound ATP, we conclude that opening of the channel is initiated by ATP binding at the NBD2 site, and tighter binding at W401 at the NBD1 site prolongs channel open time. We then studied the role of signature sequence in channel gating. We found that micromolar [Cd] can dramatically increase the activity of G551D-CFTR. A specific region of the signature sequence is found to result in positive response to Cd. We thus conclude that signature sequence serves as a switch that transmits the signal of Cd binding to the gate opening. The Cd effect is found to work through forming a metal bridge connecting G551D/C to unknown cysteine residue in CFTR. Our data provide the first evidence that R domain is involved in the CFTR channel opening, besides its role in PKA-dependent phosphorylation.
Development of Intercultural Competence and Cultural Empathy in High School Students Participating in a Short-Term Study Abroad Exchange

A major effect of globalization is the decreasing importance of national borders in favor of international economic cooperation. However, many of the issues of the imperialist era of the 16th to the 20th centuries still linger including poverty and marginalized populations of people. A space in schools exists for programs that have an ability to engage students in critical thought through cultural empathy and also prepare students for the modern, interconnected world. When education policymakers attend too much to standardized testing, school curricula do not tend to have options for such critical and empathic education. Through opportunities such as Short-Term Study Abroad (STSA) programs, educators can help to develop intercultural competence among participants. In this dissertation, I investigated the relationship between participation in a 10-day secondary school STSA exchange program to Denmark, and student intercultural competence development. Using Mezirow’s (1997) Transformative Learning Theory as a theoretical framework, I utilized a mixed methods approach in order to measure changes in participants’ intercultural competence before and after participation the exchange. Through this study, I found that high school who participated in a carefully-structured secondary school STSA exchange program experienced significant development in their intercultural competence. Students who took part in this program had opportunities to process cultural differences in meaningful ways and engaged in critical thought through interventions such as journal reflections and group interviews. This dissertation offers several suggestions for implementing successful STSA programs at the high school level.
Gap opening and large spin–orbit splitting in (M = Mo,W; X = S,Se,Te) from the interplay between crystal field and hybridisations: insights from ab-initio theory

Abstract By means of first-principles density functional calculations, we study the maximally localised Wannier functions for the 2D transition metal dichalcogenides (M = Mo,W; X = S,Se,Te). We have found that part of the energy gap is opened by the crystal field splitting induced by the -like atoms. The inversion of the band character between the and the K points of the Brillouin zone is due to the M–M hybridisation. The consequence of this inversion is the closure of the gap in absence of the M–X hybridisation. The M–X hybridisation is the only one that tends to open the gap at every k-point. It is found that the change in the M–X and M–M hybridisation is the main responsible for the difference in the gap between the different dichalcogenide materials. The inversion of the bands gives rise to different spin–orbit splitting at and K point in the valence band. The different character of the gap at and K point offers the chance to manipulate the semiconducting properties of these compounds. For a bilayer system, the hybridisation between the out-of-plane orbitals and the hybridisation between the in-plane orbitals split the valence band respectively at the and K point. The splitting in the valence band is opened also without spin–orbit coupling and occurs due to the M–M and X–X hybridisation between the two monolayers. The transition from direct to indirect band gap is governed by the hybridisation between out-of-plane orbitals of different layers and in-plane orbitals of different layers.
Confined Pressure Calibration for 3 GPa Molten Salt Medium Triaxial Pressure Vessel under High Pressure and Temperature

A triaxial deformation apparatus with 3 GPa molten salt medium pressure vessel was developed.It is based on the conventional Griggs design and the molten salt cell concept modified.There is a huge difference between apparent confined pressure and true confined pressure due to the friction in the assembly and the strength of the confined medium under high temperature and pressure.In this study,we used the partially molten method of LiCl-KCl to make the confined pressure calibration on the basis of the temperature calibration.We successfully observed the simultaneous variation of confined pressure displacement,axial stress and temperature disturbance when the specimen molten initially,then we calculated the true confined pressure by the given equation.Finally,we obtained a series of true confined pressure under different apparent confined pressure of 300~1 400 MPa.Additionally,we gave a interpretation about the friction in the pressure vessel.When the pressure is at 300~500 MPa,the friction percentage changed from 52% to 31.2% gradually.When the pressure is 700~1 200 MPa,the friction percentage dropped about 11.4%. When the pressure is 1 400 MPa,the friction percentage showed a slightly rise from 11.4% to 15.5%. The true confined pressure of the new pressure vessel is not only more accurate than the old one,it has reached the same level with the similar apparatus in other laboratories of the world.

R&D intensity and abnormal stock returns

Technology is one of the most important drivers in the current economy. Many firms listed on the U.S. stock exchange conduct research and development (R&D) activities in order to gain competitive advantages. However, R&D activity negatively impacts the reported financial performance of a firm due to the current accounting rules. Under current U.S. accounting standards, intangible assets are not reported and R&D spending is expensed. Previous research has analyzed whether a potential positive relation between R&D expenditure and future abnormal stock returns exists. Some studies concluded R&D intensity is positively associated with abnormal returns, others concluded this was due to the interaction effect of other variables. This study provides new evidence, based on more recent observations, a positive relation between the level of R&D intensity of a firm and the abnormal stock return exists. A portfolio analysis is conducted to compare different measures of R&D intensity and to determine whether high R&D intensity firms experience higher abnormal returns. Companies with a high level of R&D intensity also tend to be more resilient in times of economic distress.

Solid acid catalyzed synthesis of furans from carbohydrates

ABSTRACT The alternative feedstock, biomass (particularly lignocelluloses), having the profuse availability, is promising for the synthesis of several value-added chemicals which are currently obtained from fossil feedstock. In this article, the synthesis of two extremely significant furan chemicals viz. furfural and 5-hydroxymethylfurfural (HMF) are discussed. In the synthesis of furans from biomass, numerous challenges, i.e., use of edible sugars as substrates, selectivity to furans, their isolation in pure form, reuse of catalyst, environmental issues, etc., are perceived and in the recent past researchers tried to resolve those by developing advance methodologies. This article comprehensively summarizes the latest progress made in the above-mentioned areas and also provides commentary on the analyses of results, rationale for observed activity and mechanisms, etc. It also discusses future aspects of this work.
Superior Sodium Storage in Na2Ti3O7 Nanotube Arrays through Surface Engineering

Sodium‐ion batteries have attracted extraordinary attention owing to their low cost and raw materials in abundance. A major challenge of practical implementation is the lack of accessible and affordable anodes that can reversibly store a substantial amount of Na ions in a fast and stable manner. It is reported that surface engineered sodium titanate (Na2Ti3O7) nanotube arrays directly grown on Ti substrates can serve as efficient anodes to meet those stringent requirements. The fabrication of the nanotube arrays involves hydrothermal growing of Na2Ti3O7 nanotubes, surface deposition of a thin layer of TiO2, and subsequent sulfidation. The resulting nanoarrays exhibit a high electrochemical Na‐storage activity that outperforms other Na2Ti3O7 based materials. They deliver high reversible capacities of 221 mAh g−1 and exhibit a superior cycling efficiency and rate capability, retaining 78 mAh g−1 at 10 C (1770 mA g−1) over 10 000 continuous cycles. In addition, the full cell consisting of Na2Ti3O7 nanotube anode and Na2/3(Ni1/3Mn2/3)O2 cathode is capable of delivering a specific energy of ≈110 Wh kg−1 (based on the mass of both electrodes). The surface engineering can provide useful tools in the development of high performance anode materials with robust power and cyclability.
Rubber Seed Oil Properties, Authentication and Quality Assessment Using (Chloroform: Methanol) as Solvent

Physicochemical and instrumental characterization of rubber (Hevea brasiliensis (kunth. Muell.)) seed oil (RSO) were carried out for the purpose of quality assessment, identification, and authentication. Properties such as free fatty acid (FFA %), acid value, color, saponification value, iodine value, and unsaponifiable matter were determined. Fatty acid (FA) composition and TAG profiles were determined using gas chromatography (GC) and high performance liquid chromatography (HPLC), respectively. Structural features of RSO were also determined using FTIR, 1 H NMR and 13 C NMR spectroscopy. The natural form of RSO is highly acidic (acid value=17.43±0.06 mg KOH/g). The saturated FAs are palmitic (9.10±0.06) and stearic (12.63±0.01), and the main unsaturated FAs are oleic (25.31±0.13), linoleic (36.31±0.09), and linolenic (15.78±0.18). The oil can be classified as semidrying. Polyunsaturated TAGs of LnLnL and LnOO were the major TAGs found in RSO. FTIR, 1 H NMR and 13 C NMR analysis confirmed

An Experimental and Modeling Study of the Adsorption Equilibrium and Dynamics of Water Vapor on Activated Carbon

In this work, the adsorption of water vapor on a commercial activated carbon is studied by means of static and dynamic measurements. To this end, two customized setups are used, which are able to deal with the challenges associated with adsorption measurements under humid conditions. In the first part, the equilibrium of water vapor on activated carbon during adsorption and desorption at 45 °C is characterized. The equilibrium adsorbed amount of water vapor exhibits a pronounced hysteresis loop, requiring the use of an isotherm model with hysteresis to describe the data. In the second part, fixed-bed experiments for both adsorption and desorption conditions at three feed velocities are presented. These dynamic experiments are described by a nonisothermal detailed column model, which considers the linear driving force model for mass transfer and axial dispersion. Heat and mass transfer coefficients are estimated so as to describe the fixed-bed experiments. The results from the static and dynamic measuremen.
Magnetic granulometry from equilibrium magnetization measurements: Mineral magnetometry of superparamagnetic particles and application to synthetic ferrihydrites

Abstract Mineral magnetometry is underused in characterizing natural and synthetic nanophase, nanoparticle, and nanocomposite materials, where it has certain advantages over more sophisticated methods, such as high-resolution microscopies and synchrotron-based spectroscopies. We developed the physical theory of direct current (dc) field equilibrium magnetometry of non-exchange coupled superparamagnetic (SP) particles and determined the most information that can be extracted from field and temperature curves, exactly and without making physical assumptions other than those inherent in superparamagnetism and equilibrium measurements. We gave expressions for all field strengths and we did not make any a priori assumptions about the shapes of the distributions of particle size and of supermoment magnitude (μ) or about any relationship between particle size and particle moment. The extracted number average particle mass, {m}, and extracted moments, {μn}, of the number distribution of μ are valid irrespective of particle shapes and sizes, of the nature of the (magnetocrystalline or other) anisotropy barrier, of dipolar inter-particle interactions, and of the mechanism of formation of the supermoment (antiferromagnetic mismatch, surface pinning, etc.). We generalized the approach further to treat composite samples that included: (1) a magnetically inert (diamagnetic) matrix phase, (2) various populations of paramagnetic (PM) cations, and (3) contributions from ferrimagnetic (FI) and ferromagnetic (FM) phases. We applied these methods to synthetic 2-line ferrihydrites coprecipitated with different anion species (nitrate or sulfate) and to a synthetic 6-line ferrihydrite. These are the first accurate evaluations of μ and its relation to particle size in ferrihydrite. The particle masses agree with known sizes for similar synthetic samples. The μ/m ratios (i.e., intrinsic mass magnetization values) are consistent with a significantly higher degree of intra-particle order in 6-line ferrihydrite and gave insight into the supermoment formation mechanism.
