Recognizing Top-Monotonic Preference Profiles in Polynomial Time
Authors: Magiera Krzysztof , Faliszewski Piotr 
Published: September 2019

We provide the first polynomial-time algorithm for recognizing if a profile of (possibly weak) preference orders is top-monotonic. Top-monotonicity is a generalization of the notions of single-peakedness and single-crossingness, defined by Barbera and Moreno. Top-monotonic profiles always have weak Condorcet winners and satisfy a variant of the median voter theorem. Our algorithm proceeds by reducing the recognition problem to the SAT-2CNF problem.

Abstract

Background
Oncology research increasingly involves biospecimen collection and data sharing. Ethical challenges emerge when researchers seek to use archived biospecimens for purposes that were not well defined in the original informed consent document (ICD). We sought to inform ongoing policy debates by assessing patient views on these issues.

Materials and Methods
We administered a cross-sectional self-administered survey to patients with cancer at an academic medical center. Survey questions addressed attitudes toward cancer research, willingness to donate biospecimens, expectations regarding use of biospecimens, and preferences regarding specific ethical dilemmas.

Results
Among 240 participants (response rate 69%), virtually all (94%) indicated willingness to donate tissue for research. Most participants (86%) expected that donated tissue would be used for any research deemed scientifically important, and virtually all (94%) expected that the privacy of their health information would be protected. Broad use of stored biospecimens and data sharing with other researchers increased willingness to donate tissue. For three scenarios in which specific consent for proposed biobank research was unclear within the ICD, a majority of patient's favored allowing the research to proceed: 76% to study a different cancer, 88% to study both inherited (germline) and tumor specific (somatic) mutations, and 70% to permit data sharing. A substantial minority believed that research using stored biospecimens should only proceed with specific consent.

Conclusion
When debates arise over appropriate use of archived biospecimens, the interests of the research participants in seeing productive use of their blood or tissue should be considered, in addition to addressing concerns about potential risks and lack of specific consent.

<p>Energy is an extensive view for industrial advancement. Solar thermal energy is designed by light and heat which is radiated by the sun, in the form of electromagnetic radiation. Solar energy is the highest promptly and sufficiently applicable authority of green energy. Impact of nanoparticle shapes on the Hiemenz nanofluid (water-based Cu, Al2O3 and SWCNTs) flow over a porous wedge surface in view of solar radiation energy has been analyzed. The three classical form of nanoparticle shapes are registered into report, i.e. sphere (m=3.0), cylinder (m=6.3698) and laminar (m=16.1576). Nanoparticles in the water-based Cu, Al<sub>2</sub>O<sub>3</sub> and SWCNTs have been advanced as a means to boost solar collector energy through explicit absorption of the entering solar energy. The controlling partial differential equations (PDEs) are remodeled into ordinary differential equations (ODEs) by applying dependable accordance alteration and it is determined numerically by executing Runge Kutta Fehlberg method with shooting technique. It is anticipated that the lamina shape SWCNTs have dynamic heat transfer attainments in the flow improvement over a porous wedge surface as compared with the other nanoparticle shapes in different nanofluid flow regime.</p><p> </p>

Published: September 2019

<p>Light hydrocarbons are treated as a by-product of the petrochemical industry. They are clean and inexpensive fuels that not only less pollute the environment but also save valuable energy. Through the analysis of light hydrocarbon fuel development status, people now use light hydrocarbon for gasiﬁcation combustion. This usage requires high quality of light hydrocarbon and strict safety. The feasibility of using light hydrocarbon gas as fuel to replace diesel in oil boilers has been proposed for the current industrial boilers in China, and the sources of light hydrocarbon fuels and the safety of such alternative technologies have been speciﬁcally described. We believe such replacement can effectively reduce the dependency of the international oil market. </p>

Objective: To evaluate the clinical efficacy of combined anterior and posterior approach surgery for patients with spinal type. Methods: 96 patients with cervical spondylosis were randomly selected among all patients admitted in our hospital from January 2013 to December 2015. They were evenly assigned to A, B or C group, 32 patients each. Patients in Group A suffered from cervical myelopathy and were treated by combined anterior and posterior approach. Patients in Group B group suffered from cervical vertebra disease and accepted a cervical corpectomy decompression and a bone graft fusion internal fixation surgery. Patients in Group C accepted conventional posterior decompression and fusion surgery for lateral mass screw fixation. Postoperative follow-up, X-ray intervertebral stability and fusion, neurological function JOA score and clinical efficacy of the effective date were compared. Results: JOA scores of all three groups were improved after 6 months. After a year, patients in Group A, B and C scored (16.3 ± 1.83), (15.7 ± 1.15) and (15.59 ± 1.21), respectively. The pairwise score differences between any two groups were statistically significant (P &lt; 0.05). After one year’s follow-up, the bone graft and internal fixation material had no signs of loosening, displacement or subsidence. The fusion rates of Group A, B and C reached 90.6%, 53.1% and 56.25%, respectively. Similarly, the pairwise differences in fusion rate between any two groups were statistically significant (P &lt; 0.05). The clinical effectiveness was classified as apparent, effective, fair and invalid. The effective rates of Group A, B and C were 87.5%, 50% and 56.2%, respectively. The pairwise differences between any two groups were statistically significant (P &lt; 0.05). Conclusion: Combined anterior and posterior approach surgery significantly improved the clinical efficacy than the other two surgeries.

Published: September 2019

A Amazônia brasileira compreende um conjunto único de paisagens e dinâmicas socioecológicas interdependentes, configuradas por uma diversidade de atores, ecossistemas, usos da terra e práticas de manejo de recursos naturais. No entanto, a sociedade brasileira e global vivencia um momento de alto risco em relação Ã sustentabilidade da mega biodiversidade das paisagens amazônicas. A transformação e degradação destes ambientes decorre do modelo de desenvolvimento adotado no país, em conjunto com o modelo político e fatores associados como mudanças climáticas, desmatamento, uso intensivo da terra para agropecuária, mineração, implementação de infraestrutura de forma inadequada, contaminação por agrotóxicos, entre outros. Estaremos Ã beira de um limiar (em inglês, “threshold”) de transformação dos sistemas socioecológicos amazônicos, para ambientes mais secos, menos diversos e mais vulneráveis ao fogo, inundações, insegurança alimentar etc.? Como estabelecer um processo de governança para a Amazônia, considerando e respeitando a sua socio-biodiversidade, neste cenário de transformação?

Published: September 2019

Purpose of the study: The objective of the study was to analyze the perceptions of tahfiz students in understanding the meaning of the verses and their knowledge of the Arabic language syntax and morphology in memorizing the Qur’an. Design/methodology/approach: For this article, the study sample is comprised of 30 tahfiz students at the Azhar Institute of Qiraat in Shobra, Cairo, Egypt. They were chosen as a minimum sample of 30 population tahfiz students who had followed an Arabic Course in Malaysia. The survey method uses a Likert scale-based questionnaire which measures the levels of understanding among tahfiz students, which includes the overall mastery of Qur’anic understanding and the structure of the Arabic language’s syntax and morphology. The data were then analysed using IBM SPSS Statistics to identify the mean values of each item. Findings: The results of this study reveal that the level of understanding of Arabic grammar and morphology of the Qur’an amongst tahfiz students is high. Research Implications: This study recommends to explore the possibility of establishing a curriculum framework that gives provision for the Arabic language to be mastered by students in tahfiz institutions. Once this curriculum is implemented, the tasks of Qur’anic educators will be made easier. Social Implications: The study throws light on the integrated approach in memorizing the Qur'an will produce tahfiz students who are able to master the memorization effectively. Originality/Value: Only a very few have examined the proficiency of the Arabic language and its function to the ḥuffaz in memorizing the Qur'an effectively. Most of the issues often faced by ḥuffaz who are non-native Arabic speakers are closely related to their mastery, or lack thereof, of the Arabic language. Since memorizing the Qur’an involves proper understanding of the purpose and structure of the language, there is a need to carry out a study concerning the same.

Published: September 2019

Kooi and Tamminga's correspondence analysis is a technique for designing proof systems, mostly, natural deduction and sequent systems. In this paper it is used to generate sequent calculi with invertible rules, whose only branching rule is the rule of cut. The calculi pertain to classical propositional logic and any of its fragments that may be obtained from adding a set (sets) of rules characterizing a two-argument Boolean function(s) to the negation fragment of classical propositional logic. The properties of soundness and completeness of the calculi are demonstrated. The proof of completeness is conducted by Kalmár's method.
Most of the presented sequent-calculus rules have been obtained automatically, by a rule-generating algorithm implemented in Python. Correctness of the algorithm is demonstrated. This automated approach allowed us to analyse thousands of possible rules' schemes, hundreds of rules corresponding to Boolean functions, and to nd dozens of those invertible. Interestingly, the analysis revealed that the presented proof-theoretic framework provides a syntactic characteristics of such an important semantic property as functional completeness.
Dialektyka oporu. Edukacja jako proces odkrywania znaczeń
Authors: Łojek-Kurzętkowska Maria 
Published: September 2019

Dominujący w nowoczesności podział praktyk edukacyjnych na dwa niezależne elementy: czynnik poznawczy i emocjonalny, doprowadził do nieadekwatnego pojmowania podmiotu i celu działań edukacyjnych. Stosowanie aparatu pojęciowego związanego z wymianą usług oraz kształtowaniem kompetencji kluczowych, spowodowało zredukowanie działań edukacyjnych do czynników ekonomicznych. Celem artykułu jest ukazanie znaczenia pojęcia oporu jako ogniwa łączącego element kognitywny i emocjonalny w nauczaniu. W tekście przyjęte jest założenie, iż osiągnięcie autonomii moralnej przez wychowanków uznaje się za cel działań edukacyjnych. Pierwsza część tekstu stanowi analizę pojęć samowiedzy, podmiotowości i oporu obecnych w Fenomenologii ducha Georga Wilhelma Friedricha Hegla. W drugiej części rozważań pojęcia te odniesione zostają do problematyki współczesnej edukacji moralnej. Przedstawiona zostaje językowa koncepcja edukacji autorstwa Paula Standisha, podkreślająca rolę czynnika emocjonalnego w kształtowaniu autonomii moralnej wychowanków. Pojęcie oporu edukacyjnego okazuje się być koniecznym ogniwem łączącym dwie istotne perspektywy: samoświadomość wychowanka i dyskursowy świat, składający się ze społecznie uwarunkowanych aktów mowy.
Real-Time Pricing of Smart Grid Based on Piece-Wise Linear Functions
Authors: Xu Zhihong , Guo Liangyu , Gao Yan , Hussain Muhammad , Cheng Panhong 
Published: September 2019

Abstract
In a power grid system, utility is a measure of the satisfaction of users’ electricity consumption; cost is a monetary value of electricity generated by the supplier. The utility and cost functions represent the satisfaction of different users and the supplier. Quadratic utility, logarithmic utility, and quadratic cost functions are widely used in social welfare maximization models of real-time pricing. These functions are not universal; they have to be discussed in detail for individual models. To overcome this problem, a piece-wise linear utility function and a piece-wise linear cost function with general properties are proposed in this paper. By smoothing the piece-wise linear utility and cost functions, a social welfare maximization model can be transformed into a differentiable convex optimization problem. A dual optimization method is used to solve the smoothed model. Through mathematical deduction and numerical simulations, the rationality of the model and the validity of the algorithm are verified as long as the elastic and cost coefficients take appropriate values. Thus, different user types and the supplier can be determined by selecting different elastic and cost coefficients.

Published: September 2019

Abstract
This paper deals with the effort problem under multiple risks in bivariate utility setting. We identify preference conditions to insure positive or negative effect of a background variable uncertainty on effort in the presence of other risks. We allow for the simultaneous presence of wealth and background variable uncertainties. We investigate the joint effect of two-source uncertainties on effort when two risks are either small or positive quadrant dependent. Our work extends the previous model of effort to bivariate utility framework and presents new insights into the issue of optimal effort under uncertainty.
A New Technique for Simultaneous Measurement of Nanodarcy-Range Permeability and Adsorption Isotherms of Tight Rocks Using Magnetic Suspension Balance
Authors: Ratnakar Ram R. , Dindoruk Birol 
Published: September 2019

Summary
Flow and adsorptive characteristics of methane and other natural gases onto tight rock formations are of economic interest for proper engineering evaluation and reservoir performance management. This work presents a novel technique to enable the simultaneous determination of nanodarcy permeability and adsorption isotherms of gas in such formations through the transient analysis of experimental data from magnetic suspension balance (MSB).
MSB has primarily been shown to be an effective tool for evaluating the amount of gases adsorbed onto tight shales/coals, especially when the adsorbed amount is small. In addition to the classical usage of the measured data using MSB, a new mathematical model based on volume averaging has been developed to describe the transient behavior of the adsorption phenomenon and to obtain the nominal or apparent permeability of shale samples from experimental data. Historically, the permeability of nanoporous materials is measured using two leading methods: the Gas Research Institute method and the pressure–pulse–decay method; however, neither of these methods yields information about the adsorptive behavior of the porous medium or considers such phenomena. In this study, we developed a simple theoretical framework to obtain the isotherm of gas adsorption onto a tight shale (or other tight materials such as coal) sample and the permeability of the sample, simultaneously. The results show that the permeability vs. pressure plot follows the Klinkenberg effect at lower pressures, as expected. The overall methodology developed here can be applied to any type of adsorbing gases and shale/coal samples. The utility and validity of the methodology are demonstrated by applying the developed methodology in experiments performed on three tight shale samples (unconventionals) using two different gases: methane and CO2.
