Generation Z & Y preferences of user acceptance of mobile health recommender systems

Mobile health (mHealth) applications provide equal reach to health care services at an affordable cost. mHealth can play a major role in enhancing the quality and access of health services in developing countries, still the adoption of mHealth in these countries is very low. On the other hand, younger generations have great dependence on mobile devices and have high potential to adopt mobile applications. The aim of this study is to investigate factors that affect user acceptance of mobile health recommender system among Generations Z (between 10 and 25 years old) & Y (between 26 and 40 years old). The research adopts Technology Acceptance Model (TAM3) constructs and extends them to include constructs related to Trust and Reputation, as mHealth is prone to uncertainty and vulnerability. Based on 136 valid responses collected from a survey, structural equation modelling SEM was employed to examine the research questions. The data were analyzed using the Partial Least Squares (PLS) method. The results suggested that for generations Z & Y, Perceived Usefulness has a significant positive effect on behavioral intention to use mobile health recommender system. This direct relationship is affected by user characteristics, namely gender and experience using technology. Perceived Ease of Use and Trust in mHealth applications, significantly increase the Perceived Usefulness. The results reveal the importance of perceived reputation in building Trust in mHealth applications, and it is found that Output Quality has a positive influence on Reputation. Computer anxiety has a negative effect on Perceived Ease of Use. These findings provide a basis for improving the understanding toward factors affecting mHealth applications in developing countries. The study provides number of practical design recommendations for designers and service providers.
Miscentring in Galaxy Clusters: Dark Matter to Brightest Cluster Galaxy Offsets in 10,000 SDSS Clusters

We characterise the typical offset between the Dark Matter (DM) projected centre and the Brightest Cluster Galaxy (BCG) in 10,000 SDSS clusters. To place constraints on the centre of DM, we use an automated strong-lensing analysis, mass-modelling technique which is based on the well-tested assumption that light traces mass. The cluster galaxies are modelled with a steep power-law, and the DM component is obtained by smoothing the galaxy distribution fitting a low-order 2D polynomial (via spline interpolation), while probing a whole range of polynomial degrees and galaxy power laws. We find that the offsets between the BCG and the peak of the smoothed light map representing the DM, \Delta, are distributed equally around zero with no preferred direction, and are well described by a log-normal distribution with =-1.895^{+0.003}_{-0.004}, and \sigma=0.501\pm0.004 (95% confidence levels), or =0.564\pm0.005, and \sigma=0.475\pm0.007. Some of the offsets originate in prior misidentifications of the BCG or other bright cluster members by the cluster finding algorithm, whose level we make an additional effort to assess, finding that ~10% of the clusters in the probed catalogue are likely to be misidentified, contributing to higher-end offsets in general agreement with previous studies. Our results constitute the first statistically-significant high-resolution distributions of DM-to-BCG offsets obtained in an observational analysis, and importantly show that there exists such a typical non-zero offset in the probed catalogue. The offsets show a weak positive correlation with redshift, so that higher separations are generally found for higher-z clusters in agreement with the hierarchical growth of structure, which in turn could help characterise the merger, relaxation and evolution history of clusters, in future studies.

Partially Identified Econometric Models

This paper studies a class of models where full identification is not necessarily assumed. We term such models partially identified. It is argued that partially identified systems are of practical importance since empirical investigators frequently proceed under conditions that are best described as apparent identification. One objective of the paper is to explore the properties of conventional statistical procedures in the context of identification failure. Our analysis concentrates on two major types of partially identified model: the classic simultaneous equations model under rank condition failures; and time series spurious regressions. Both types serve to illustrate the extensions that are needed to conventional asymptotic theory if the theory is to accommodate partially identified systems. In many of the cases studied, the limit distributions fall within the class of compound normal distributions. They are simply represented as covariance matrix or scalar mixtures of normals. This includes time series spurious regressions, where representations in terms of functionals of vector Brownian motion are more conventional in recent research following earlier work by the author.

The Morse index theorem in Hilbert space

When does the critical point of a calculus of variations problem minimize the integral? The classical result is due to Jacobi, who proved that for a regular problem in one independent variable, the integral is minimized at a solution of the Euler-Lagrange equation up to the first conjugate point but not after. Morse extended the theorem to give a formula for the index of a critical curve in terms of the conjugate points along the curve. This result has since been generalized by Edwards [3], Simons [7] and Smale [8] to systems of higher order, minimal surfaces, and partial differential systems respectively. In this article we present an infinite dimensional proof of a general theorem on the index of a bilinear form in Hubert space which can be applied to all these cases. The first section contains the abstract formulation and proof of the main theorem (Theorem 1.11). The second section deals with single integral problems and the third with multiple integral problems. In the applications we assume less differentiability than the previous results.
Special case of Fermat's Theorem

Reproducibility of the point connection technique for measuring hallux valgus angles using a smartphone application

Objective: A) To evaluate the reliability of a new technique for the measurement of both intermetatarsal and hallux valgus angles. B) To evaluate whether this technique can be performed with the aid of a smartphone application. Methods: Preoperative radiographs of 30 patients were evaluated by four observers, two experienced surgeons and two surgeons in training. They performed measurements of the intermetatarsal angle and hallux valgus angle using the classical method and using the new method, both employing a goniometer and a smartphone application. Analysis of agreement was done by quantifying the raw agreement and calculating the intraclass correlation coefficient (ICC). Results: The hallux valgus angle presented excellent agreement (ICC>0.80) both using the traditional method and the point connection method, while the intermetatarsal angle presented a very good agreement (0.60<ICC≤0.80) in both methods. Conclusion: The point connection technique showed good concordance rates when measured by smartphone applications, although it did not prove to be superior to the traditional one.

Conclusion: In this study we observed a marked geographic variation in the relative frequency of various salivary gland neoplasms in Cairo government.
What to Measure

One of the rst questions the algorithmic experimenter faces is: What should I measure? This talk will focus on measuring solution quality, and will survey a variety of performance indicators that can be considered when undertaking computational research on algorithms. Some performance indicators such as the number of colors used, the length of the tour, or the number of problem instances solved to optimality are immediately suggested by the context of the algorithmic problem. However, alternative performance indicators may produce better experimental results. I will draw on a variety of nontraditional statistical methodologies, including graphical analysis, exploratory data analysis, variance reduction techniques, and use of biased estimators, to show how alternative performance indicators can lead to more e cient and powerful experiments, clearer analyses, and stronger conclusions about algorithm performance.
Proving First-Order Equality Theorems with Hyper-Linking

Lee and Plaisted recently developed a new automated theorem proving strategy called hyper-linking. As part of his dissertation, Lee developed a round-by-round implementation of the hyper-linking strategy, which competes well with other automated theorem provers on a wide range of theorem proving problems. However, Lee's round-by-round implementation of hyper-linking is not particularly well suited for the addition of special methods in support of equality. In this dissertation, we describe, as alternative to the round-by-round hyper-linking implementation of Lee, a smallest instance first implementation of hyper-linking which addresses many of the inefficiencies of round-by-round hyper-linking encountered when adding special methods in support of equality. Smallest instance first hyper-linking is based on the formalization of generating smallest clauses first, a heuristic widely used in other automated theorem provers. We prove both the soundness and logical completeness of smallest instance first hyper-linking and show that it always generates smallest clauses first under a large class of ordering on clauses. We discuss which of the refinements used by Lee in round-by-round hyper-linking are also applicable to smallest instance first hyper-linking. We add equality support to smallest instance first hyper-linking using unfailing completion, narrowing, and Brand's equality transformation in a method we call unfailing completion equality support. We show the soundness and logical completeness of smallest instance first hyper-linking with unfailing completion equality support. We also show that Brand's equality transformation is unnecessary for the case where all positive equational literals occur in equational Horn clauses. In particular, this means that for pure equational problems, smallest instance first hyper-linking with unfailing completion equality support simply reduces to an application of unfailing completion. We conclude the dissertation by describing our preliminary implementation of smallest instance first hyper-linking. We present a comparison of our implementation with that of Lee's on the 2,655 problems in the TPTP Problem Library of Sutcliffe and Suttner.
Evaluation of the efficacy of Chlorella vulgaris extract against cutaneous leishmaniasis in white laboratory mice of Balb/c

The current study aimed to evaluate the effectiveness of Chlorella vulgaris extract against the parasite Leishmania major that causes cutaneous leishmaniasis and compare it with ivermectin drug in vivo. This study was conducted in the animal house of the Department of Biology / Faculty of Education for Girls / University of Kufa, and the study period extended from 1/11/2021/ to 1/4/2022. The current study included evaluating the effectiveness of the crude alcoholic extract of C. vulgaris compared with Ivermectin drug in vivo (white mice) where the current study included the use of two concentrations of alcoholic algae extract (500, 1000) mg/ml and one concentration of the drug 2%. The results of the current study showed a decrease in the size of the pest in the group treated with alcoholic extract of the moss. With an increase in the concentration compared to the drug and the positive control group, as the size of the pest treated with the extract became 1000 mg/ml after 15 days of treatment, 0.5 cm, while the size of the pest in the group treated with the drug was 1.2 cm.
Neonatal Feeding Intolerance and Its Characteristics: A Descriptive Study

Background: Feeding intolerance (FI) is common in preterm infants leading to feeding and gastrointestinal disruptions. FI in newborns can be a sign of a variety of problems, ranging from minor, self-limiting illnesses to serious ones. Many causes are found to cause FI such as low intestinal motility, bacterial colonization, hormonal response, and local immunity response. We aim to find out the characteristics of full-term neonates with FI during the neonatal hospitalization period. Methods: This is a descriptive study that was conducted at King Hamad University Hospital in Bahrain. Our targeted population included neonates with FI. Full-term neonates (gestational age, GA >36 weeks) with lower than 1 week of age were included. Data were investigated and compared with the mode of delivery. Results: In this study, 46 neonates were included and their characteristics of FI were evaluated. The most common symptoms observed in neonates with FI were vomiting (91.3%) and abdominal distension (8.7%). Of the total cases, 52.2% of neonates were born through Cesarean section (C-section), while 47.8% had a vaginal delivery. All the neonates had normal APGAR (Appearance, Pulse, Grimace, Activity, and Respiration) scores. C-section cases had more vomiting problems than vaginal delivery cases. Abdominal distention was noted more in neonates born via vaginal delivery when compared to C-section. Conclusion: During hospitalization after birth, refusal to feed with frequent vomiting or abdominal distension is a common characteristic of FI in neonates. Newborns with this condition require constant monitoring and supportive care from competent nurses.
CP VIOLATION IN $B \to C\bar{C}D$ DECAYS AT BELLE

We report a measurement of the CP violation parameters in b->c anti-c d decays. Mixing-induced CP violation involving this transition is studied using a sample of B0->J/psi pi0, D*+D*- and D*+-D-+ decays with a data set accumulated at the Upsilon(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. CP violation parameters are extracted from a fit to the distributions of time intervals between two B0 meson decay vertexes.
Nanomaterials in recycled aggregates concrete applications: mechanical properties and durability. A review

Abstract The use of recycled aggregates concrete (RAC) contributes effectively to reduce CO2 emissions from concrete manufacturing process while also protecting natural resources by utilizing existing available concrete as an aggregates source for a new one. Studies on the behaviour of RAC have revealed negative effects on concrete strength and microstructure development, resulting in deterioration of mechanical and durability properties. As a result, numerous practical studies have been implemented to enhance the RAC properties using various treatment techniques such as chemical, physical and heating treatments. However, most of these techniques are ineffective compared to conventional concrete applications due to poor mechanical performance of RAC, insufficient environmental requirements, and prolonged treatment times. Recently, the use of nanomaterials has been given significant concern in RAC research. Their nano-sized particles can help to reduce micropores formation by acting as a filling agent to produce a high-density microstructure, thereby enhancing the mechanical properties and durability of RAC. This had led to a wide range of studies being published on improving RAC properties by using nanomaterials. However, relatively few literatures had been conducted on the effects of different types of nanomaterials on the performance of RAC exposed to various types of loads and various external environmental impacts. Besides, the conditions used by authors in these literatures limit comparisons, and in some cases contradictory findings are observed. Thus, this paper aims to bridge the knowledge gap between researchers. This would allow the potential of nanotechnology in innovations to be applied in appropriate areas of RAC applications to benefit the general public good. This paper aims to provide a critical review and comprehensive conclusions on the performance of nano-modified RAC under external loads, environmental impacts and other various conditions. The effects of nanomaterials on the compressive, tensile, and flexural strength of RAC are discussed. The nanomaterials considered are nano-SiO2, nano-CaCO3, nano-TiO2, nano-Clay, nano-Al2O3, and nano-Carbon. Durability characteristics including water absorption, chloride penetration, fire exposure, abrasion resistance, acid and carbonation diffusions are extensively discussed. Microstructure characteristics using SEM, XRD, EDS, and micro-hardness of nano-modified RAC are addressed as well.

Background: The main purpose of this study is to evaluate the oral health of diabetic patients through the application of Knowledge, Attitude and Practices (KAP), since periodontitis considered to be one of the complications of diabetes. Methods: This cross-sectional study was conducted at THQ hospital, Kahuta district Rawalpindi, where 104 diabetic patients were selected as study participants. Data was collected by using a structured questionnaire and further analysis was done by using SPSS 21. Results: The study showed that only 38.5% of the participants had adequate knowledge regarding oral manifestations of diabetes. The oral health attitudes and compliance of suggested oral cleanliness practices were also poor. The study results showed that 55% of the diabetic patients brushed their teeth once a day. While only 16.3% brushed twice a day. 39.4% of the participants did not visit the dental clinic within the last 1 year. Conclusion: The study concluded that knowledge about the oral complications was deficient in the diabetic patients. There is need to improve the oral health knowledge of the diabetic patients along with emphasis on adaptation of oral hygiene practices, regular dental visits and strict glycemic control.
Propagation and Chemical Mutgenic Induction of Eustoma Grandiflorum Plant Using Tissue Culture Technique

Mutagenesis is one of the powerful tools for breeding biotechnology. Chemical mutagenesis is an easy tool, which doesn’t require special tools and provide high mutation rate. Effects of different cytokines (BA, 2ip and Kim at 0.4 mg/l) on in vitro shootlet proliferation of Eustoma grandiflorum were studied. Different concentrations of colchicine (30, 60, 120 and 240 mg/l) and sodium azide (5, 10, 15 and 20 mg/l) were added to free-hormone MS medium. In vitro shootlets, of Eustoma grandiflorum, were culture for 7, 14 and 28 days. After each treatment period, the shootlets were transferred to fresh MS medium free (without the chemical mutagenesis). At acclimatization stage, most of morphological parameters and anthocyanin pigment contents in flower recorded decline by most treatments of sodium azide. All colchicine treatments reached to morphological stage and formed bud initiation and death before flowering. Contrary, highest survival % of acclimatized plants (70%) and highest values of number of branches, branches length (cm), leaf area (cm2), most of floral parameters, photosynthetic pigments, carotenoids and anatomical structure were obtained from ( 5,10 mg/l sodium azide for 28, 7 days) and (60, 30mg colchicine for 28 days).
Model Predictive Control of Three-Phase Four Switch Inverter-Fed Induction Motor Drives

: -- The four-switch three-phase (B4) inverter has the possibility of reducing the inverter cost, and it became very attractive in fault-tolerant control to solve the open/short-circuit faults of the six-switch three-phase (B6) inverter. Its application is limited due to the fluctuation of the two dc-link capacitor voltages which causes the unbalance among the phase currents. Predictive torque control (PTC) scheme is proposed for the B4 inverter-fed induction motor (IM) with the dc-link voltage offset suppression. For precise prediction and control of the torque and stator flux, the voltage vectors of the B4 inverter under the fluctuation of the two dc-link capacitor voltages are derived. By directly controlling the stator flux, the three-phase currents are forced to stay balance. The voltage offset of the two dc-link capacitors is modeled and controlled in the predictive point of view.
