Personalized active learning for collaborative filtering
Venue: SIGIR '08
Year: 2008

Collaborative Filtering (CF) requires user rated training examples for statistical inference about the preferences of new users. Active learning strategies identify the most informative set of training examples through minimum interactions with the users. Current active learning approaches in CF make an implicit and unrealistic assumption that a user can provide rating for any queried item. This paper introduces a new approach to the problem which does not make such an assumption. We personalize active learning for the user, and query for only those items which the user can provide rating for. We propose an extended form of Bayesian active learning and use the Aspect Model for CF to illustrate and examine the idea. A comparative evaluation of the new method and a well established baseline method on benchmark datasets shows statistically significant improvements with our method over the performance of the baseline method that is representative for existing approaches which do not take personalization into account.
Review on the effects of potential prebiotics on controlling intestinal enteropathogens Salmonella and Escherichia coli in pig production
Venue: Journal of animal physiology and animal nutrition
Year: 2018

Salmonella enterica serotypes (Salmonella sp. are the second cause of bacterial foodborne zoonoses in humans after campylobacteriosis. Pork is the third most important cause for outbreak associated salmonellosis, and colibacillosis is the most important disease in piglets and swine. Attachment to host cells, translocation of effector proteins into host cells, invasion and replication in tissues are the vital virulence steps of these pathogens that help them to thrive in the intestinal environment and invade tissues. Feed contamination is an important source for Salmonella infection in pig production. Many on farm feeding strategies intervene to avoid the introduction of pathogens onto the farm by contaminated feeds or to reduce infection pressure when pathogens are present. Among the latter, prebiotics could be effective at protecting against these enteric bacterial pathogens. Nowadays, a wide range of molecules can potentially serve as prebiotics. Here, we summarize the prevalence of Salmonella sp. and Escherichia coli in pigs, understanding of the mechanisms by which pathogens can cause disease, the feed related to pathogen contamination in pigs and detail the mechanisms on which prebiotics are likely to act in order to fulfil their protective action against these pathogens in pig production. Many different mechanisms involve the inhibition of Salmonella and E. coli by prebiotics such as coating the host surface, modulation of intestinal ecology, downregulating the expression of adhesin factors or virulence genes, reinforcing the host immune system.
Laboratory modelling of grouting in poorly graded sand
Year: 2019

This paper presents a newly designed laboratory apparatus for grouting in poorly graded sand. Sandy soil specimen was prepared by a wet raining method. Bleeding tests were carried out to select a cement bentonite mixture with minimal bleeding. Both water injection tests and grout injection tests were conducted to investigate the threshold seepage velocity, the fracture initiation pressure, and factors affecting the fracture initiation pressure using a plot of injection pressure (p) against injection rate (q) Under low q value, the development of p q curve was not relevant to the overburden pressure applied and the p value was generally in a proportional linear relationship with the q value. It is also noted that for the same q value, the fracturing pressure required was increased with an increase in effective overburden pressure. Vertical oriented fractures were formed and then turned to a horizontal orientation. The subsequent turning of the fractures might be related either to the minimum compressive stress somehow being increased during the test or to the inhomogeneous nature of the sand specimen.
Culturally competent care for nontraditional family structures
Year: 2013

Cultural competency applies not only to minority ethnic or religious groups but also to nontraditional family structures. A review of the evidence based literature and clinical practice tips will be highlighted for the following family types: children being raised in multicultural or bilingual families, children of same gender parents, children being raised by grandparents or in multigenerational families, and transracial adopted children. Same sex parenting alone does not appear to be a risk factor for poor outcomes in children. There is no statistical certainty that distinguishes the developmental, psychological, or social outcomes of children raised by same gender parents to that of children raised by opposite gender parents, when socioeconomic levels of the families are equal. Conversely, children raised by grandparents have an increased incidence of behavioral and emotional disturbances and therefore may require extra attention to mental health needs. Grandparents may face many challenges when they unexpectedly have to step in to care for a grandchild: housing difficulties, financial, feelings of guilt or grief, loss of independence, and work limitation, thus, the grandparents themselves have an increased likelihood of depression and several other chronic medical conditions. There have been a vast number of studies on domestic and international adoption, which demonstrate that transracial adoption itself does not place a child at a higher risk for emotional and behavioral problems. Children of racial or ethnic minorities who are adopted into a family of the ethnic or racial majority, however, are at a potential risk for ethnic identity confusion. Feelings of discrimination and ethnic identity confusion appear to be less prevalent in transracial adopted children whose parents engage in a variety of cultural socialization strategies. Hispanics are more likely than non Hispanic whites to live in multicultural households. Certain child rearing practices may be interpreted as abusive if the provider is unfamiliar with the family's culture, thus being familiar with the cultural practices of the most common local ethnicities is critical. Utilization of professionally trained medical interpreters if bilingual providers are not available can assist with language barriers as well as clarification of cultural beliefs. As the family physicians of these children and their parents or caregivers, we not only need to be informed about and be sensitive to their special concerns, but also have a responsibility to incorporate current evidence based information in our approach.
Advanced Processing of Remotely Sensed Big Data for Cultural Heritage Conservation
Venue: IGARSS 2019 2019 IEEE International Geoscience and Remote Sensing Symposium
Year: 2019

Damage assessment, protection and preservation of built patrimony are a priority at national and local levels due to their importance to many cultural and economic aspects. This paper presents a methodology to estimate the potential damage caused by ground settlement for cultural heritage buildings using remotely sensed big data. Specifically, it presents a framework to assess the potential damage caused by ground settlement for masonry, infilled and bare frames structures using Persistent Scatterer Interferometric (PSI) measurements. The proposed solution advances the state of the art by integrating big Earth observation (EO) environmental, architectural and historical data, for estimating the settlement induced damage to hundreds thousands of buildings. The fully automatic scheme was created within cloud computing environment for accelerating data transfer, processing and modeling and for improving the visualization of image derived products.
A value theoretic approach to economic dynamics and evolution synthesizing different Marxian modules in a simulation model
Year: 2020

This part is devoted to simulation experiments based on the simulation model developed in part I from the value theoretic reconstruction of the main parts of Marx's critique of Political Economy. After introducing the main parameters and the range of their variation (Section 1) a singular run as well as a sensitivity analysis for the chosen standard configuration 'moderation regime' is presented in Section 2. This is accomplished by configurations depicting characteristics of the capitalist development emphasized by Marx, i.e. the social conflict regime (Section 3) and the crisis regime (Section 4) Finally, an assessment of the simulation results (Section 4) is given, and conclusions as well as research requirements are discussed (Section 5)

Venue: Journal of Functional Analysis
Year: 2019

We prove that if (X,\mathsf d,\mathfrak m) is an essentially non branching metric measure space with \mathfrak m(X)=1$ having Ricci curvature bounded from below by $K$ and dimension bounded from above by $N \in (1,\infty) understood as a synthetic condition called Measure Contraction property, then a sharp isoperimetric inequality `a la L\'evy Gromov holds true. Measure theoretic rigidity is also obtained.
Automatic Reviewers Assignment to a Research Paper Based on Allied References and Publications Weight
Venue: 2018 4th International Conference on Computing Communication and Automation (ICCCA)
Year: 2018

Everyday there may be a vast stream of research documents give in to conferences, anthologies, journals, newsletters, annual report, daily paper, and different periodicals. Numerous such publications use unbiased and exterior specialists to survey. This methodology is frequently termed peer review, in addition the assessors are named referees. but it is not always possible to pick out the best referee for reviewing. Moreover, the new fields of research are emerging in every sector and the number of research is increasing dramatically. but, to review all of these papers, every journal assign a short team of referees and maybe they are not expert in all areas. For example, a research paper in the communication technology area should be reviewed by the expert from the same field. So, it is a big challenge to efficiently select the best reviewer or referee for a research paperIn this research work, we proposed and implemented a program or software where, we used a new strategy to select the best reviewers of a research work automatically. As we already know that every research paper contains references in the end of the paper and the references are generally from same area as the paper is. In this work, first of all, we collect the references and count the authors who have at least one paper that belong to the reference section. Once, we collect the authors name, automatically browse the web to extract the research topic keywords. Then again search for finding top researchers in the specific topic field and count their h index, i10 index and citations for first n author. After then, ranked top n authors based on ranking score and automatically browse their homepage to retrieve emails address. We also check their co authors and colleagues from the web and discard them accordingly from the list. The remaining tops n authors (researcher) generally professor and maybe the best referees for reviewing a research paper.

Pesticides pollution: Classifications, human health impact, extraction and treatment techniques
Year: 2020

The word "pesticides" is a complex word that encompasses all compounds that are applied to destroy or regulate pests; this includes insecticides (insects) herbicides (weeds) and fungicides (fungi) One of the primary sponsors of the green revolution was finding ways to improve and use safe pesticides to control the wide range of herbal and insect pests, which affect negatively the quantity and quality of world food production. This review provides an analysis of pesticides' definition, classifications, toxicity, factors affecting toxicity, pesticides in water resources, their environmental fate, impacts on human health and their methods of detection, disposal and treatment. Moreover, this work gives a brief description of the extraction methods used for pesticides analysis besides comparing the analytical techniques used to measure the very low concentration of pesticides. Finally, this work suggests to find further alternative methods to identify the pesticide residues and other highly hazardous pollutants.
Extracellular Matrix Mediated Differentiation of Human Embryonic Stem Cells: Differentiation to Insulin Secreting Beta Cells
Year: 2014

Stem cells have tremendous potential for treating various human diseases. Protocols have been established to differentiate stem cells into specific lineages through the provision of signals in the form of growth factors, cytokines, or small molecules. Herein we investigate an alternative strategy for directed differentiation of human embryonic stem cells (hESCs) extracellular matrix (ECM) mediated differentiation. Decellularized ECM and conditioned media from the appropriate committed cell lines are used to differentiate stem cells to the required phenotype. Applying this strategy to differentiate hESCs to pancreatic beta cells, we have obtained functional cells that secreted insulin in a glucose responsive manner, and were able to recover normoglycemia in a streptozotocin (STZ) induced diabetic mouse model. ECM mediated differentiation was also demonstrated to be effective for the differentiation of hESCs into kidney tubule cells and cardiomyocytes. Gene expression studies suggested the involvement of in.
Three Essays on CEO Risk Preferences, and Ability, Corporate Hedging Decisions, and Investor Sentiment
Year: 2018

THREE ESSAYS ON CEO RISK PREFERENCES, AND ABILITY, CORPORATE HEDGING DECISIONS, AND FIRM VALUE Sonik Mandal Old Dominion University, 2018 Director: Dr. John A. Doukas The derivative hedging research has looked at why firms and how firms hedge and if it increases value for their shareholders. In this dissertation we investigate the relation between CEO risk preferences and ability and whether if affects their hedging decisions and firm value. In our first essay, we challenge the theory and previous empirical evidence that showed CEO risk preferences affects hedging. Using a sample of Fortune 500 firms and 5 years of panel data, and using inside debt (i.e. CEO pension and deferred compensation) and the CEO Vega and CEO Delta, as proxies of CEO risk preferences, we document that neither risk averse (i.e. debt like compensation) nor risk seeking (i.e. convex compensation) inducing CEO compensation packages influence corporate hedging. Moreover, we find CEOs who have more previous work experience and high job tenure to be positively related to hedging. Essay 2 examines the hedging intensity and market value sensitivity of firms run by CEOs with different risk preferences. We find derivatives hedging intensities of risk seeking and risk averse CEOs to be fairly similar, suggesting that compensation contracts designed to motivate risk seeking (less hedging) behavior do not succeed to alter CEOs' inherent riskaversion. We also find, that if the underline asset prices change by three standard deviations the average firm's derivatives portfolio creates only modest gains for both types of CEOs. These results seem consistent with the view that hedging is just an insurance policy and not a firm value

Secure Data Retrieval Using Blockchain
Year: 2020

Medical IoT devices are gradually being widely used, and acquisition requirements such as image type and quantity are also changing. Retrieving medical images can help diagnose the condition and improve treatment timeliness. However, medical images contain a large amount of sensitive patient information, which can easily cause privacy leakage. At the same time, existing research cannot protect the sensitive information of medical images or achieve data sharing. Therefore, it is of practical significance to study the realization of medical image data sharing and retrieval under privacy protection. This chapter proposes a medical image retrieval system based on emerging blockchain technology that can protect image privacy and give a system model and a threat model. Later, we not only capture specific feature vectors based on medical images but also design the transaction structure accordingly, so as to achieve the purpose of privacy protection.
A neurocognitive investigation of the impact of socializing with a robot on empathy for pain
Venue: Philosophical Transactions of the Royal Society B
Year: 2019

To what extent can humans form social relationships with robots? In the present study, we combined functional neuroimaging with a robot socializing intervention to probe the flexibility of empathy, a core component of social relationships, towards robots. Twenty six individuals underwent identical fMRI sessions before and after being issued a social robot to take home and interact with over the course of a week. While undergoing fMRI, participants observed videos of a human actor or a robot experiencing pain or pleasure in response to electrical stimulation. Repetition suppression of activity in the pain network, a collection of brain regions associated with empathy and emotional responding, was measured to test whether socializing with a social robot leads to greater overlap in neural mechanisms when observing human and robotic agents experiencing pain or pleasure. In contrast to our hypothesis, functional region of interest analyses revealed no change in neural overlap for agents after the socializing intervention. Similarly, no increase in activation when observing a robot experiencing pain emerged post socializing. Whole brain analysis showed that, before the socializing intervention, superior parietal and early visual regions are sensitive to novel agents, while after socializing, medial temporal regions show agent sensitivity. A region of the inferior parietal lobule was sensitive to novel emotions, but only during the pre socializing scan session. Together, these findings suggest that a short socialization intervention with a social robot does not lead to discernible differences in empathy towards the robot, as measured by behavioural or brain responses. We discuss the extent to which long term socialization with robots might shape social cognitive processes and ultimately our relationships with these machines. This article is part of the theme issue 'From social brains to social robots: applying neurocognitive insights to human robot interaction'
Competing Against Luck: The Story of Innovation and Customer Choice
Year: 2016

The foremost authority on innovation and growth presents a path breaking book every company needs to transform innovation from a game of chance to one in which they develop products and services customers not only want to buy, but are willing to pay premium prices for. How do companies know how to grow? How can they create products that they are sure customers want to buy? Can innovation be more than a game of hit and miss? Harvard Business School professor Clayton Christensen has the answer. A generation ago, Christensen revolutionized business with his groundbreaking theory of disruptive innovation. Now, he goes further, offering powerful new insights. After years of research, Christensen and his co authors have come to one critical conclusion: our long held maxim that understanding the customer is the crux of innovation is wrong. Customers don't buy products or services; they "hire" them to do a job. Understanding customers does not drive innovation success, he argues. Understanding customer jobs does. The "Jobs to Be Done" approach can be seen in some of the world's most respected companies and fast growing startups, including Amazon, Intuit, Uber, Airbnb, and Chobani yogurt, to name just a few. But this book is not about celebrating these successes it's about predicting new ones. Christensen, Hall, Dillon, and Duncan contend that by understanding what causes customers to "hire" a product or service, any business can improve its innovation track record, creating products that customers not only want to hire, but that they'll pay premium prices to bring into their lives. Jobs theory offers new hope for growth to companies frustrated by their hit and miss efforts. This book carefully lays down the authors' provocative framework, providing a comprehensive explanation of the theory and why it is predictive, how to use it in the real world and, most importantly, how not to squander the insights it provides.
