Budget-Limited Multi-armed Bandit Problem with Dynamic Rewards and Proposed Algorithms

We focus on budget-limited multi-armed bandit (BL-MAB) problems in which an agent's actions are costly and constrained by a fixed budget. The existing BL-MAB problems assume that reward distributions are static. In this paper, we assume that rewards are dynamic since it is much more realistic. For example, the effect of online advertising, which is one real-world application of BL-MAB problems, is dynamic for trends and dates. For dynamic situations we propose two new bandit algorithms: D-KUBE and SW-KUBE. D-KUBE uses discounted rate gamma. SW-KUBE uses scope tau. In our experiments, we compared the existing bandit algorithm with our proposed bandit algorithms. The main contributions of this paper can be described as follows: (1) When the reward distributions are static, KUBE, D-KUBE, and SW-KUBE have almost the same results. (2) When the reward distributions are dynamic, our proposed D-KUBE and SW-KUBE outperform KUBE. (3) The total rewards of the abrupt changes case are better than those of the gradual changes case.

THE EFFECTIVENESS OF GALERY WALK TECHNIQUE TOWARD GRAMMAR COMPETENCE OF ENGLISH DEPARTMENT STUDENTS OF UNHASY

Almost all of the students who learn English assume that learning grammar of English is not so important. They often think that their English is already acceptable in every condition without good grammar. This assumption makes their care on how important grammar is for their English less. It causes their grammar competence becomes low. Besides, the lecturer’s way of teaching which is not interesting also gives contribution to this low competence. This pre-experimental research was done by implementing gallery walk technique which is believed as an interesting and challenging teaching technique in intermediate English grammar class. The objectives of this research were to know: (1) the students’ grammar competence before the implementation of gallery walk technique, (2) the students’ competence on grammar after being taught by using GWT and (3) the effectiveness of GWT towards students’ grammar competence. The population of this study was two classes of the third semester students of English language eduacation department of UNHASY in the academic year of 2019/2020. The sample was class B comprising of 19 students by using purposive sampling. The students’ average score of grammar before GWT was applied was 67. After GWT was implemented, their mean score of grammar became 73. Because the value of sig. (2-tailed) was lower than 0.05, it showed that the improvement of the average results of pretest and posttest was significantly different. Then, it came to the conclusion that GWT was effective for teaching grammar.

Hydrophobicity and specific biofilm features of Bacillus cereus spores subjected to pH stresses

Bacillus cereus is a foodborne pathogen that often persists on food processing surfaces due the formation of spores and biofilms. Spores of 12 selected B. cereus strains from genotypes that recurred in a pasteurized milk processing line were investigated in this study, for their surface and biofilm characteristics. The main objective was to have an insight into their persistence strategies. Spore surface hydrophobicity and acid-base properties, were assessed using the microbial adhesion to solvents (MATS) method. To determine how hydrophobicity was affected by cleaning procedures, this property was measured when spores were submitted to alkali or acidic stresses mimicking those of cleaning-in-place (CIP) procedures. Biofilms formation on stainless steel coupons by pH-treated spores was investigated in three culture media and imaged by using environmental scanning electron microscopy (ESEM). Results showed that spores were either hydrophilic or moderately hydrophobic. Alkali-stress reduced spore surface hydrophobicity, whereas acidic shock increased it. More limited hydrophobicity changes following alkaline stress suggest alkali adaptation of spores. In addition, spores submitted to pH-stresses produced specific biofilm features on stainless steel as shown by ESEM imaging. Alkali tolerance and the biofilm lifestyle are strategies that permit B. cereus recurrent genotypes to persist in the milk processing line. Overall, this study gives an insight into hydrophobicity and specific biofilm features of B. cereus spores submitted to chemical cleaning. Key words: Bacillus cereus, biofilms, spores, hydrophobicity, CIP-like stress, dairy industry, environmental scanning electron microscopy (ESEM).

Review of the UK air quality index

This is the first report prepared by the Standards Advisory Subgroup (CSAS) of the Committee on the Medical Effects of Air Pollutants. The subgroup was formed in June 2009 when the Expert Panel on Air Quality Standards (EPAQS) was merged with COMEAP. The work of the subgroup is supported by a joint Secretariat from both the Department for Environment, Food and Rural Affairs (Defra) and the Health Protection Agency. In 2009, the subgroup was asked by Defra to review the current UK air quality index. Since the air quality index was last revised in 1998, there have been a number of developments in the regulation of air pollution and in the presentation of air quality information, which are reflected in these proposals. COMEAP is very keen to enhance the way we communicate facts about air pollution to the public and the findings from the public insight study, which was commissioned by Defra, have been invaluable for developing the health advice and the presentation of the index. I am grateful to Stephen Holgate, the Chairman of the Standards Advisory Subgroup, who has ensured that the needs of the public for clear information were central to the development of these proposals. I am also grateful to the Secretariat and Members of the subgroup who developed the report and, indeed, to all Members of COMEAP. This is a real advance in helping the public deal with the impact of polluted air. I look forward to seeing how these proposals are received by Defra.

Geologic and Engineering Implications of Production History From Five Mesaverde Wells in Central Piceance Creek Basin, Northwest Colorado

Summary Five gas wells completed in low-permeability rocks of the Upper Cretaceous Williams Fork and Iles formations in the central part of the Piceance Creek basin, northwest Colorado, have been on continuous production for about 2 years. A general comparison is made between these wells and the Dept, of Energy 's Multiwell Experiment (DOE MWX) wells about 30 miles [48 km] to the southeast. The five wells were completed with gelled KC1 water/sand fractures in various intervals over a 3,000-ft [910m] section of largely fluvial and paludal rocks of the Williams Fork and Iles formations of the Mesaverde group. Flow has apparently stabilized at low flowing tubing pressures at a rate of 30 to 125 Mcf/D [0.84 to 3.5 × 103 m3/d] per well, with minor water and variable condensate volumes. On the basis of production information to date, attempts to select intervals with better-than-average effective permeabilities by state-of-the-art techniques were not successful. The study points out several important differences in the Mesaverde group between the area of the five wells and the MWX site. Formation temperatures are higher and levels of thermal maturity are lower in the area of the five wells than at the MWX site. High formation pressures were encountered in the lower part of the Williams Fork and Iles formations at the MWX site, while thus far, only near normal to slightly below normal pressures have been encountered in the Mesaverde group in the area of the five wells. Gas shows and gas production characteristics in the area of the five wells appear to be related in part to the availability of gas-generating source rocks. Gas shows are sparse in the upper 1,000 to 1,700 ft [305 to 520 m] of the Williams Fork formation, where good source rocks are uncommon. Gas shows generally occur in only the upper parts of sandstones in this interval, suggesting that discrete gas/water contacts (GWC 's) are present. Completion attempts in this interval are commonly hindered by higher-than-average volumes of formation water. In contrast, almost continuous gas shows occur throughout the remainder of the Williams Fork formation and underlying Iles formation, where good source rocks are abundant. Discrete GWC 's are rare in this interval. Completions in this part of the section are capable of sustaining continuous gas production. The differences in the Mesaverde group between the MWX site and the area of the five wells point out the need to expand the MWX data base to include other gasproducing areas in the Piceance Creek basin.

Child Undernutrition and Infant and Young Child Feeding Indicators: A Secondary Analysis of Edhs 2011

Background: - Optimal Infant and Young Child Feeding (IYCF) practices play an important role in reducing early childhood morbidity and mortality, as well as in improving early child growth and development. There are different predictors of child nutritional outcomes like economic and contextual factors. But infant nutritional status (stunting, wasting and underweight) can be associated with an immediate cause such as infant feeding practice. Objectives: To determine the association between WHO core IYCF indicator and different forms of child under nutrition in Ethiopia. Methods: Data from the 2011 Ethiopia Demographic Health Surveys (EDHS), which is nationally representative data, were used. The study subjects were Last born infants and their mothers.Analyses were conducted using multiple linear regression and logisticregression analyses adjusted for the complex survey design of the survey, controllingfor child, maternal and household characteristics.Regression models used the 'svy' command in STATA to ensure that standard errors &amp;adjusted for the complex survey design. Result: A total of 3826 children are included in the analysis. After adjusting for possible confounders minimum acceptable diet (AOR 0.39, 95%CI 0.18-0.84) &amp; minimum diet diversity with (AOR 0.48 95% 0.24-0.96) was found to be significantly associated with stunting. Similarly minimum acceptable diet (AOR 0.36, 95%CI 0.13-0.98) &amp; minimum diet diversity (0.33 95%CI (0.12-0.87) was found to be significantly associated with underweight. Among the IYCF indicators only minimum meal frequency (AOR 0.70, 95% 0.51-0.96) was found to be significantly associated with wasting.But exclusive breastfeeding (EBF) had no association with underweight. Conclusion &amp; Recommendation: Achieving Minimum acceptable diet and minimum diet diversity are protective against stunting and underweight. And minimum meal frequency was still protective against wasting. Programmatic interventions that support a focus on complementary feeding and EBF should be implemented.

Unveiling the Dynamics of User Engagement: Exploring Factors Shaping User Intentions and Return Behavior in Hotel Gamified Mobile Applications

ABSTRACT The surge in mobile technologies has prompted extensive research, driven by the widespread adoption of mobile devices and advancements in related technologies. Within the hospitality industry, mobile applications have fundamentally altered consumer behavior, highlighting the insufficiency of merely establishing a mobile presence for increased engagement. In contrast, the gaming industry has effectively explored factors influencing usage, achieving both engagement and profitability. The evolution of mobile gaming applications suggests ample opportunity for the proliferation of gamified applications. Utilizing quantitative data from 763 mobile users with hotel visitation experience, using CFA the study identifies six factors (i.e., perceived ease of use, perceived enjoyment, interactivity), that collectively play a crucial role in influencing users' decisions not only to initially adopt but also to revisit and sustain their interaction with hotel gamified mobile apps. The research enriches theoretical understanding of mobile use behavior in the hospitality sector, offering valuable insights for hotel marketers to optimize the design and promotion of gamified mobile applications, thereby shaping users' return behavior.

The Role of Individual- and Contextual-Level Social Capital in Product Boycotting: A Multilevel Analysis

Product boycotts represent an important form of sustainable consumption, as withholding purchasing can restrain firms from damaging the natural environment or breaking social rules. However, our understanding of consumer participation in these protests is limited. Most previous studies have focused on the psychological and economic determinants of product boycotting. Drawing on social capital literature, this study builds a framework that explains how individual- and contextual-level social capital affects consumer participation in boycotts of products. A multilevel logistic regression analysis of 29 country representative samples derived from the European Social Survey (N = 54221) shows that at the individual level product boycotting is associated with a person’s social ties, whereas at the country level, generalized trust and social networks positively affect consumer decisions to take part in these protests. These results suggest that to better understand differences among countries in consumer activism, it is necessary to consider the role of social capital as an important predictor of product boycotting.

Salt tolerance of lactose-grown Vibrio parahaemolyticus carrying Escherichia coli lac genes

Lac- strains of Vibrio parahaemolyticus were converted to Lac+ on receiving a hybrid plasmid containing the lactose utilization genes of Escherichia coli K-12. A V. parahaemolyticus strain containing this hybrid plasmid exhibited optimal growth rates on glucose and other carbon sources in the presence of 0.2 to 0.4 M NaCl. Growth of the same strain on lactose was inhibited at similar concentrations of NaCl. The altered growth rate responses in lactose medium appeared to be attributable to effects of NaCl on the activity of lactose permease, and possibly on that of beta-galactosidase, rather than on the levels of these enzymes in V. parahaemolyticus cells.

An image destriping method combining feature extraction and nonlinear fitting

With the development of semiconductor technology, the performance of many new image sensors, such as infrared focal planes and CMOS image sensors, have been improved. Also, it is an alternative choice of CCD, vacuum tube or other equipment that promotes this kind of sensors to become the mainstream of the market. However, this kind of image sensors has a weakness that is the stripe noise, due to the inconsistent readout circuit response. This noise influences the quality of image directly, as a result, the poor image quality in-benefits for recognition and classification. Thus, how to remove the stripe noise arises the interests for many researchers. Most of them only focus on one certain type of stripe features, instead of combining different features together, leading to the poor performance of denoising. This paper proposes a method of removing stripes that combines feature extraction and function fitting. Firstly, extract the statistics and spatial position of the stripes, and then perform two steps of rough processing and fine processing on the image. The PSNR, SSM value show that the algorithm meets the design expectations and has a certain degree of robustness.

Phase Locking of SWL Array Junctions in Submillimeter Mixing

We have fabricated a submillimeter mixer with two SWL (short-weak-link) junctions connected in series. This mixer has been used for a 337 GHz fundamental mixing. It has been found that these two junctions independently contribute the IF (intermediate frequency) output when the applied LO (local oscillator) power is small, but that they behave just as a single junction for the increased LO power.

In Silico DISCOVERY OF NOVEL HEPATITIS C VIRUS P7-TRANSACTIVATED PROTEIN1INHIBITOR BY USING STRUCTURE-BASED VIRTUAL SCREENING

Hepatitis C Virus (HCV) infection is a serious cause of chronic liver disease worldwide with more than 170 million infected individuals at a risk of developing significant morbidity and mortality.Till date there is no effective drug for the treatment or vaccine to prevent this infection.The present study aims in discovering novel inhibitors which target an allosteric binding site of P7-transactivated Protein1 of HCV.Virtual screening uses computer-based methods to discover new ligands on the basis of biological structures.A structure based virtual screening of Zinc database by computational docking and the post docking analysis of energy calculations and interactions followed by ADMET studies were conducted.The approach adopted was receptorbased.Docking screens, guided with contact pharmacophores and neural-network activity prediction models on all allosteric binding sites and MD simulations, constituted our analysis workflow for identification of potential hits.Steps included: 1) Using two phases docking screen with moe and Glide Xp programs, 2) Ranking based on scores, and important H interactions.From the final hits, we selected best 10 compounds for further anti-HCV activity and cellular cytotoxicity assay.All 10 compounds have more potential to be 104 MAHMOUD EL HEFNAWI et al. considered as lead compoundsto inhibit ion channel activity of p7 with docking score and binding energy (E_score) values ranging from -16.5087 to -15.8089 and all these compounds displayed no cellular cytotoxicity.Finally, 10 hit compounds of different scaffolds having interactions with important active site residues were predicted as lead candidates.These candidates having unique scaffolds have a strong likelihood to act as further starting points in the optimization and development of novel and potent p7 ion channel inhibitors.

Development of Boccia Play Support System Based on Fingertip Operation

It is important for the patients with neurological difficulties such as ALS and SMA to improve their quality of life. We focused on the sport called Boccia that can be played even by people with relatively severe disabilities, and the ultimate goal is to construct the system for patients with intractable diseases. In this research, we developed the Boccia play support system which can allow the disabled player to determine both the direction of the lamp and the launch height of the ball, and to launch the ball using movable body part, on the assumption that it can be remotely controlled. Here we paid attention to the slight movement of fingertip. The skin surface on the fingertips was observed with USB camera, and the amount of movement of feature points on the skin surface was derived by using optical flow, and a non-contact interface based on skin strain detection was developed.
