Preemptive Scheduling with Controllable Processing Times on Parallel Machines
Authors: Liu Guiqing , Li Kai , Cheng Bayi 
Published: August 2017

AbstractThis paper considers several parallel machine scheduling problems with controllable processing times, in which the goal is to minimize the makespan. Preemption is allowed. The processing times of the jobs can be compressed by some extra resources. Three resource use models are considered. If the jobs are released at the same time, the problems under all the three models can be solved in a polynomial time. The authors give the polynomial algorithm. When the jobs are not released at the same time, if all the resources are given at time zero, or the remaining resources in the front stages can be used to the next stages, the offline problems can be solved in a polynomial time, but the online problems have no optimal algorithm. If the jobs have different release dates, and the remaining resources in the front stages can not be used in the next stages, both the offline and online problems can be solved in a polynomial time.
Heavy OWA Operator of Trapezoidal Intuitionistic Fuzzy Numbers and its Application to Multi-Attribute Decision Making
Authors: Luo Chunlin , Tian Xin , Wan Shuping 
Published: August 2017

AbstractHeavy ordered weighted averaging (OWA) operator is important for characterizing the decision maker’s attitudinal character in multi-attribute decision making (MADM) problem with part or total ignorance. This paper develops a new method based on heavy OWA operator to solve the MADM problem in which the attributes are characterized by some trapezoidal intuitionistic fuzzy numbers (TrIFNs). TrIFN, as a special kind of intuitionistic fuzzy set defined on the real numbers, is useful for characterizing the ill-known quantity in reality. Firstly, the operation laws and the cut sets concept for TrIFNs are introduced. Then the authors define the membership and non-membership average indexes. A new ranking method is developed on the basis of the two indexes. In the proposed decision model, the multi-attribute TrIFN values of the candidates are aggregated by the Heavy OWA operator, and ranked by their membership and non-membership average indexes. Lastly, the authors illustrate the proposed method by a numerical example which implies the practicality and effectiveness of the method.

Abstract
In order to explore the effect of wettability and pore throat heterogeneity on oil recovery efficiency in porous media, physical simulation experiment and nuclear magnetic resonance (NMR) measurements were conducted to investigate how crude oil residing in different sized pores are recovered by water flooding. Experimental results indicate that the recovery factor of water flooding is governed by spontaneous imbibition and also pore throat heterogeneity. It is found that intermediate wetting cores lead to the highest final recovery factor in comparison with water wet cores and weak oil wet cores, and the recovery oil difference in clay micro pore is mainly because of the wettability, the difference in medium pore and large pore is affected by pore throat heterogeneity. Water wet core has a lower recovery factor in medium and large pore due to its poor heterogeneity, in spite of the spontaneous imbibition effect is very satisfying. Intermediate wetting cores has significant result in different sized pore and throat, the difference in medium pore and large pore is affected by pore throat heterogeneity.

Estimation for coefficient of variation of an extension of the exponential distribution under type-II censoring scheme
Authors: Bakoban Rana A. 
Published: August 2017

AbstractThe coefficient of variation [CV] has several applications in applied statistics. So in this paper, we adopt Bayesian and non-Bayesian approaches for the estimation of CV under type-II censored data from extension exponential distribution [EED]. The point and interval estimate of the CV are obtained for each of the maximum likelihood and parametric bootstrap techniques. Also the Bayesian approach with the help of MCMC method is presented. A real data set is presented and analyzed, hence the obtained results are used to assess the obtained theoretical results.
Evaluation of polypropylene hybrid composites containing glass fiber and basalt powder
Authors: Barczewski Mateusz , Matykiewicz Danuta , Mysiukiewicz Olga , Maciejewski Paweł 
Published: August 2017

Abstract
Polypropylene composites filled with inorganic fillers are widely used due to their good mechanical and thermal properties. The modification efficiency of filler incorporated into thermoplastic polymer strongly depends on its shape and dimension. Therefore, the development of novel hybrid composites modified with particle and fibrous shaped fillers expands the range of thermoplastic composite applications. This work investigates the influence of glass fiber and basalt powder and their shape on the mechanical properties of polypropylene-based composites. Mechanical properties of hybrid composites were evaluated using static tensile test, impact resistance, and hardness measurements. The thermomechanical stability of the materials was evaluated via dynamic mechanical thermal analysis. Results indicated that the incorporation of inorganic fillers significantly improved the composite sample stiffness at a wide range of temperatures. The research was complemented with structure investigations realized using scanning electron microscopy. Moreover, the incorporation of basalt powder, which is well known for its low friction coefficient, improved the processing properties, as proven by the melt flow index test.
An Empirical Investigation of Oil-Macro-financial Linkages in Saudi Arabia
Authors: Miyajima Ken 
Published: August 2017

AbstractAgainst the backdrop of low oil prices, oil-macro-financial linkages in Saudi Arabia are analyzed by applying panel econometric frameworks (multivariate and vector autoregression) to macro- and micro-level data for 9 banks spanning 1999–2014. Lower growth of oil prices and nonoil private sector output leads dampen credit and deposit growth and lift nonperforming loan ratios. Positive feedback loops within bank balance sheets in turn dampen economic activity. U.S. interest rates are not found to be a key determinant. The banking system remains strong at present, but policy makers should monitor its health with the important macro-financial feedback loops in mind.
Iconoclasms of Emmett Till and his killers in Lewis Nordan’s Wolf Whistle: A new generation of historiographic metafiction
Authors: Vayo Brendon 
Published: August 2017

Abstract
In this essay, I argue that the apparent historical inaccuracies contained within Lewis Nordan’s Wolf Whistle (Nordan, Lewis. 2003 [1993]. Wolf Whistle. Chapel Hill: Algonquin) represent a systematic repeal of the controversial history surrounding the murder of Emmett Till in 1955. Nordan reconstitutes the principle characters to function as iconoclasms of the historical record. As iconoclasms, these representations undermine our culture’s accepted model of history, what Hayden White terms the “historical account” (White, Hayden. 1975. Metahistory: The historical imagination in nineteenth-century Europe. Baltimore: Johns Hopkins University Press: 30).
A semiosic translation of the term “Bild” in both the Tractatus Logico-Philosophicus and The Philosophical Investigations
Authors: Torres-Martínez Sergio 
Published: August 2017

Abstract
This paper introduces and defends a way to translate Wittgenstein’s Tractatus Logico-Philosophicus and the Philosophical Investigations from a semiotic standpoint. This turn builds on Semiosic Translation (Torres-Martínez 2015, Semiosic translation: A new theoretical framework for the implementation of pedagogically-oriented subtitling. Sign Systems Studies 43(1). 102–130), a framework that advances the interaction of sign systems as a necessary point of departure in the translation process. From this vantage, the key term “Bild,” is analyzed, explained and retranslated into English. This term evinces high levels of complexity and variability that cannot be captured by traditional linguistic translations. In applying a semiotic approach, any iteration of Bild is characterized as reflecting the author’s intentions at a given moment (PI: 108). This semiotic reading seeks to provide semioticians, translators, and philosophers with new conceptual tools leading to an understanding of translation as a systemic operation not confined to the realm of subjective interpretation.
The study of the future, social forecasting, mutations: Semiotic challenges and contributions
Authors: Ceriani Giulia 
Published: August 2017

Abstract
The research fieldwork dedicated to trend analysis and foresight/forecast scenarios building, represents an unusual raid in an area where economic and social sciences have invested many efforts. Nevertheless, the semiotic dimension of this subject is not sufficiently thorough; many issues are at stake:

–
the definition criteria of the corpus;

–
the selection of trend signals, the selection criteria;

–
the narrative framework of scenarios;

–
the deep logic permitting to describe the relationships between the trends and to trace their evolution;

–
the prevision as mutation logic, anticipation exercise, simulation activity;

–
the different application contexts of the anticipation science.

We are going to investigate this area of analysis, for its relevance in post-Greimassian studies, for its interface with social sciences, as well as for its relevance for the legitimacy of semiotics in contemporary discussions of innovation and evolution.
Greimas and gender: Mere recipe or real meal?
Authors: Bostic Heidi 
Published: August 2017

AbstractHow may Greimassian narrative semiotics join forces with feminist inquiry? This essay begins with an analysis of a cake recipe from Alasdair MacIntyre’sAfter Virtueand A. J. Greimas’s “Basil Soup, or the Construction of an Object of Value.” MacIntyre and Greimas raise the issue of gender in distinct ways. MacIntyre’s dismissive attitude toward traditionally feminine household duties contrasts with Greimas’s careful analysis and his unexpected invocation of a law that had a major impact on French women’s lives. The essay discusses what recipes can tell us about gender identity, and what we can learn about being a woman when narrative theorists invoke recipes. Extending the analysis, the essay points out that there is very little extant research on gender in Greimassian semiotics. Readers often assume that this type of semiotics is concerned only with “paper subjects,” that it offers a “mere recipe,” not a “real meal.” However, many of the latest innovations in Greimassian semiotics harmonize with dominant trends in the study of gender. Although Greimas did not foresee feminist analysis, his theoretical contributions certainly prepared rich ground for such work. The future is bright for additional research at the intersection of Greimas and gender.
Less Supervision, More Satisficing? Comparing Completely Self-Administered Web-Surveys and Interviews Under Controlled Conditions
Authors: Mühlböck Monika , Steiber Nadia , Kittel Bernhard 
Published: August 2017

Abstract
Although online surveys are becoming more and more prominent, the quality of the resulting data is still contested. One potential caveat of web surveys is the absence of an interviewer who controls the interview situation, can motivate respondents and prevent them from satisficing, i.e. answering questions with minimal cognitive effort. While there is evidence for differences between data gathered in interviewer-administered surveys and data from self-administered questionnaires, it has not yet been studied whether the sheer presence of an interviewer affects data quality. The present article addresses this research gap. Based on a recent panel study of young unemployed adults, we compare the results from a completely self-administered web survey with those from interviews which were self-administered but conducted in the presence of an interviewer. In particular, we look for differences concerning drop-out, speed, item-non-response, and item-non-differentiation. While we do find significant differences in drop-out rates, we do not find any evidence for interviewer-absence leading to less diligence in filling in the questionnaire. We thus conclude that the presence of an interviewer does not enhance data quality for self-administered questionnaires, but positively affects completion rates.
Ecological and phytochemical attributes of endemic Ferula gummosa Boiss. at vegetative and generative stages
Authors: Karamzadeh Leila , Jafarian Vahab , Vatankhah Elahe 
Published: August 2017

Abstract

Objective
This study was accomplished to find out the ecological as well as some biochemical and physiological properties of Ferula gummosa Boiss.

Methods
Soil samples were analysed. Different plant parts collected during different stages were analysed biochemically (catalase, peroxidase, ascorbate peroxidase and total protein) and physiologically (proline, sugars, phenolic components and photosynthetic pigments).

Results
Soil analysis showed that pH, EC and phosphatase activity were approximately 6.5–6.8, 200 μS/cm and 890 μmol/min, respectively. Among measured elements in soil, only P and Na had significantly higher concentrations at generative and vegetative stages, respectively. The biochemical and physiological analyses of F. gummosa Boiss. leaves and roots showed that the content of proline, sugar and phenolic components were significantly higher at generative stage than vegetative stage, while the content of photosynthetic pigments and activities of catalase, peroxidase and ascorbate peroxidase were significantly lower. Our qualitative analysis by sodium dodecyl sulfate polyacrylamide gel electrophoresis showed that the total protein bands of generative stage were more intensive than vegetative stage.

Conclusion
The phytochemical results strongly supported the idea that the metabolic changes were developmental-dependent.
A new cubic Ia3̅d crystal structure observed in a model single component system by molecular dynamics simulation
Authors: Lokshin Konstantin A. , Levashov Valentin A. , Lobanov Maxim V. 
Published: August 2017

Abstract
In our molecular dynamics simulations of the system of identical particles interacting through the harmonic-repulsive pair potential, we observed the formation of a cubic crystal structure that belongs to the Ia3̅d (#230) crystallographic space group. This crystal structure has not been previously seen either in experiments or in computer simulations, though its framework topology has been known from theoretical crystallographic considerations. Its unit cell contains 16 atoms, occupying only (16b) Wyckoff site, and arranged as two mutually intertwined unconnected networks with packing fraction of 0.37. The appearance of this structure is explained by the soft repulsive nature of the interaction potential. The observed Ia3̅d structure extends the small number of cubic structures formed in single component systems with spherically symmetric pair potentials in MD simulations. We speculate that materials with such structure could be found in soft matter systems or in selected crystals under high pressure.

AbstractStress and glucocorticoid (GC) release are common behavioral and hormonal responses to injury or disease. In the brain, stress/GCs can alter neuron structure and function leading to cognitive impairment. Stress and GCs also exacerbate pain, but whether a corresponding change occurs in structural plasticity of sensory neurons is unknown. Here, we show that in female mice (Mus musculus) basal GC receptor (Nr3c1, also known as GR) expression in dorsal root ganglion (DRG) sensory neurons is 15-fold higher than in neurons in canonical stress-responsive brain regions (M. musculus). In response to stress or GCs, adult DRG neurite growth increases through mechanisms involving GR-dependent gene transcription.In vivo, prior exposure to an acute systemic stress increases peripheral nerve regeneration. These data have broad clinical implications and highlight the importance of stress and GCs as novel behavioral and circulating modifiers of neuronal plasticity.
Attenuated Activity across Multiple Cell Types and Reduced Monosynaptic Connectivity in the Aged Perirhinal Cortex
Authors: Maurer Andrew P. , Burke Sara N. , Diba Kamran , Barnes Carol A. 
Published: August 2017

The perirhinal cortex (PER), which is critical for associative memory and stimulus discrimination, has been described as a wall of inhibition between the neocortex and hippocampus. With advanced age, rats show deficits on PER-dependent behavioral tasks and fewer PER principal neurons are activated by stimuli, but the role of PER interneurons in these altered circuit properties in old age has not been characterized. In the present study, PER neurons were recorded while rats traversed a circular track bidirectionally in which the track was either empty or contained eight novel objects evenly spaced around the track. Putative interneurons were discriminated from principal cells based on the autocorrelogram, waveform parameters, and firing rate. While object modulation of interneuron firing was observed in both young and aged rats, PER interneurons recorded from old animals had lower firing rates compared with those from young animals. This difference could not be accounted for by differences in running speed, as the firing rates of PER interneurons did not show significant velocity modulation. Finally, in the aged rats, relative to young rats, there was a significant reduction in detected excitatory and inhibitory monosynaptic connections. Together these data suggest that with advanced age there may be reduced afferent drive from excitatory cells onto interneurons that may compromise the wall of inhibition between the hippocampus and cortex. This circuit dysfunction could erode the function of temporal lobe networks and ultimately contribute to cognitive aging.SIGNIFICANCE STATEMENTWe report that lower firing rates observed in aged perirhinal cortical principal cells are associated with weaker interneuron activity and reduced monosynaptic coupling between excitatory and inhibitory cells. This is likely to affect feedforward inhibition from the perirhinal to the entorhinal cortex that gates the flow of information to the hippocampus. This is significant because cognitive dysfunction in normative and pathological aging has been linked to hyperexcitability in the aged CA3 subregion of the hippocampus in rats, monkeys, and humans. The reduced inhibition in the perirhinal cortex reported here could contribute to this circuit imbalance, and may be a key point to consider for therapeutic interventions aimed at restoring network function to optimize cognition.
Exosome cofactor hMTR4 competes with export adaptor ALYREF to ensure balanced nuclear RNA pools for degradation and export

AbstractThe exosome is a key RNA machine that functions in the degradation of unwanted RNAs. Here, we found that significant fractions of precursors and mature forms of mRNAs and long noncoding RNAs are degraded by the nuclear exosome in normal human cells. Exosome‐mediated degradation of these RNAs requires its cofactor hMTR4. Significantly, hMTR4 plays a key role in specifically recruiting the exosome to its targets. Furthermore, we provide several lines of evidence indicating that hMTR4 executes this role by directly competing with the mRNA export adaptor ALYREF for associating with ARS2, a component of the cap‐binding complex (CBC), and this competition is critical for determining whether an RNA is degraded or exported to the cytoplasm. Together, our results indicate that the competition between hMTR4 and ALYREF determines exosome recruitment and functions in creating balanced nuclear RNA pools for degradation and export.
Silencing of Repetitive DNA Is Controlled by a Member of an UnusualCaenorhabditis elegansGene Family

Published: August 2017

AbstractLevya-Díaz et al. identify a Caenorhabditis elegans gene involved in transgene silencing and RNA interference.Repetitive DNA sequences are subject to gene silencing in various animal species. Under specific circumstances repetitive DNA sequences can escape such silencing. For example, exogenously added, extrachromosomal DNA sequences that are stably inherited in multicopy repetitive arrays in the nematode Caenorhabditis elegans are frequently silenced in the germline, whereas such silencing often does not occur in the soma. This indicates that somatic cells might utilize factors that prevent repetitive DNA silencing. Indeed, such “antisilencing” factors have been revealed through genetic screens that identified mutant loci in which repetitive transgenic arrays are aberrantly silenced in the soma. We describe here a novel locus, pals-22 (for protein containing ALS2CR12 signature), required to prevent silencing of repetitive transgenes in neurons and other somatic tissue types. pals-22 deficiency also severely impacts animal vigor and confers phenotypes reminiscent of accelerated aging. We find that pals-22 is a member of a large family of divergent genes (39 members), defined by homology to the ALS2CR12 protein family. While gene family members are highly divergent, they show striking patterns of chromosomal clustering. The family expansion appears C. elegans-specific and has not occurred to the same extent in other nematode species for which genome sequences are available. The transgene-silencing phenotype observed upon loss of PALS-22 protein depends on the biogenesis of small RNAs. We speculate that the pals gene family may be part of a species-specific cellular defense mechanism.
