ISGylation – a key to lock the cell gates for preventing the spread of threats
Authors: Villarroya-Beltri Carolina , Guerra Susana , Sánchez-Madrid Francisco 
Published: August 2017

ABSTRACT
Interferon stimulated gene 15 (ISG15) is an ubiquitin-like protein whose expression and conjugation to targets (ISGylation) is induced by infection, interferon (IFN)-α and -β, ischemia, DNA damage and aging. Attention has historically focused on the antiviral effects of ISGylation, which blocks the entry, replication or release of different intracellular pathogens. However, recently, new functions of ISGylation have emerged that implicate it in multiple cellular processes, such as DNA repair, autophagy, protein translation and exosome secretion. In this Review, we discuss the induction and conjugation of ISG15, as well as the functions of ISGylation in the prevention of infections and in cancer progression. We also offer a novel perspective with regard to the latest findings on this pathway, with special attention to the role of ISGylation in the inhibition of exosome secretion, which is mediated by fusion of multivesicular bodies with lysosomes. Finally, we propose that under conditions of stress or infection, ISGylation acts as a defense mechanism to inhibit normal protein translation by modifying protein kinase R (PKR, also known as EIF2AK2), while any newly synthesized proteins are being tagged and thus marked as potentially dangerous. Then, the endosomal system is re-directed towards protein degradation at the lysosome, to effectively ‘lock’ the cell gates and thus prevent the spread of pathogens, prions and deleterious aggregates through exosomes.

Introduction: Implants have gained popularity in orthodontics because they facilitate maximum anchorage with minimum patient cooperation. However, some orthodontists avoid using implants because perception and experience of patients towards such anchorage systems is questionable and is not been fully reported.Aim and objectives: To evaluate the patient’s perception and experience towards the treatment with anterior microimplants for intrusion of anterior teeth using questionnaire.Materials and methods: After considering the inclusion and exclusion criteria, Participants who are undergoing orthodontic treatment with anterior implants for the intrusion of the maxillary anterior teeth was selected for the study. Questionnaire which was validated from ten respondents and subject experts will be given to each participant and asked to fill it. After collection of filled questionnaire, all the data was subjected to statistical analysis.Results: Most of the patients had enough confidence on their orthodontist and did not think to take a second opinion when an anterior implant was recommended. Majority of the patients were concerned to know regarding advantages and disadvantages of anterior microimplant and inquired about the time for the placement of anterior microimplant. More patients were worried about how long the anterior microimplant will remain inserted in their mouth and had fear of local anesthesia. On loading of microimplant, most of the patients felt pressure at the implant and few felt pain.Conclusion: The procedure was pleasant and comfortable for large number of patients and they did not felt pain after placement of anterior microimplant. Majority of the patients were satisfied with the treatment and would recommend it to other patients. Highest number of patients got used to the anterior implant by day 7 followed by day 15. An average acceptable time period for the anterior microimplant was 12 months. The overall perception and experience by the patients to the placement of anterior microimplant can be rated as expected and good.
Algoritmo para la estimación de la frecuencia instantánea en señales de fase variante en el tiempo usando la transformación local polinomial de Fourier
Authors: Cubides Herbert Enrique Rojas , Forero Mejia Maria Carolina 
Published: August 2017

La transformación local polinomial de Fourier (LPFT) es una representación tiempo-frecuencia (TFR) que generaliza los resultados obtenidos por la transformación de Fourier de corto tiempo (STFT). Esta herramienta matemática puede ser empleada para estimar la frecuencia instantánea (IF) y sus derivadas en señales no-estacionarias o señales de fase variante en el tiempo . Varias publicaciones presentan diferentes métodos para calcular la LPFT. Sin embargo, estos trabajos no describen de manera completa un algoritmo para su implementación computacional o requieren del cálculo de funciones o transformaciones adicionales. Este artículo propone un algoritmo basado en la definición de la aproximación local polinomial (LPA) y el uso del periodograma local polinomial (LPP) como estimador de la IF y sus derivadas. Así mismo, se presenta la validación del algoritmo propuesto y se consideran los errores (SRMSE) en el cálculo de los estimados de la LPFT. Finalmente, se determinan los costos computacionales a partir de un caso de estudio. Los resultados muestran que el error en el cálculo de la LPFT disminuye dependiendo del ancho de la función ventana y de la resolución dada a los posibles estimados de , aunque esto provoque un incremento en la cantidad de operaciones realizadas.
A Note on Cournot Competition in Differentiated Oligopolies
Authors: Dou Jiangli , Ye Bing 
Published: August 2017

AbstractIn this paper, we study a Cournot competition where there are a group of firms producing a homogeneous product and another group producing a differentiated product. We find that, fixing the total number of firms in the market, each firm’s profit is U-shaped and convex in the number of firms producing the same product when the degree of substitution is large, and each firm’s profit is U-shaped in the cross-price effect parameter when the number of firms producing the same product is large.
Eco-Firms and the Sequential Adoption of Environmental Corporate Social Responsibility in the Managerial Delegation
Authors: Lee Sang-Ho , Park Chul-Hi 
Published: August 2017

AbstractThis article investigates the strategic environmental corporate social responsibility (ECSR) of polluting firms in the presence of eco-firms. When the firms decide to adopt ECSR sequentially within the framework of the managerial incentive design and then face simultaneous price competition, we show that firms will adopt ECSR and purchase abatement goods to mitigate competition if the products are more substitutable, but the late adopter chooses lower ECSR and thus earns higher profit. It can partially explain the current expansive adoption of ECSR as an industry-wide wave.

Abstract
The generation of hydrogen as a chemical energy storage for power generation via fuel cells or for the synthesis of fuels has attained a strong interest in recent years. By way of example this is realized using electrolysis of water with the help of excess electricity of wind power plants. However with low temperature grade waste heat as it could be found in many industrial and household applications, there is another source of usable energy for this purpose. In a first pragmatic experimentation we investigated the pyroelectric effect of ferroelectric BaTiO3 combined with a temperature cycling to generate hydrogen from water. Therefore, single crystals ground to powder were brought into contact with distilled water and set to a cyclical temperature change from 40 °C to 70 °C. With the help of a highly selective and sensitive measuring system based on a coulometric solid electrolyte detector we could provide a first indication of pyroelectric generated hydrogen by a fraction of 300 Vol.-ppb in the sample gas.

Numerical Investigation on the Strain Evolution of Ti-6Al-4V Alloy during Multi-directional Forging at Elevated Temperatures
Authors: Yan Chenkan , Shen Jun , Lin Peng 
Published: August 2017

AbstractMulti-directional forging (MDF) is one of the most promising severe plastic deformation (SPD) methods used in fabricating large-scale bulk metal materials with ultra-fine grains (UFG). A finite element model for MDF is developed to investigate the strain evolution of Ti-6Al-4V alloy subjected to MDF. Results show that the billet subjected to MDF can be divided into four individual strain zones in terms of the equivalence of effective strain evolution, and that the strain increment in each individual strain zone varies from pass to pass. The deviation between the maximum and the minimum strain increases with the increase of passes and friction coefficient. The effective strain linearly decreases from the core to the exterior of the billet in all three directions after the MDF process. With the increase of the passes and friction coefficient, the gradient of the effective strain in the billet increases in all three directions due to the difference of deformability in different individual strain zones. For the definite friction coefficient, the average and maximum effective strains are in proportion to the accumulative compression strain.
The neurology and psychiatry of humor, smiling and laughter: A tribute to Paul McGhee. Part I. Introduction and clinical studies
Authors: Rodden Frank 
Published: August 2017

Abstract
This review article was written for people like Paul McGhee when he was 20 years old: curious and interested in the neurology and psychiatry of humor, smiling and laughter but neither physicians nor experts in cognitive science. It begins with necessary reflections on what it even means to consider humor, smiling and laughter from within these disciplines. These frames of reference, useful as they are, are far from neutral. The reader is encouraged to be sensitive to some logical and linguistic pitfalls that can fatally endanger meaningful discussions of these subjects. The results of empirical studies of humor, smiling and laughter which have employed the tools of neurology and psychiatry are then reviewed, roughly in the order in which the techniques have emerged historically, beginning with clinical studies (Part I) and continuing with current studies employing functional imaging methods in Part II. Therapeutic approaches using humor, smiling and laughter, particularly with respect to neurological and psychiatric diseases – but also including other diseases – are discussed. Finally a short synopsis of what is known about the neurology and psychiatry of humor, smiling and laughter is presented.
Conversational humor and job satisfaction at work: exploring the role of humor production, appreciation, and positive affect
Authors: Robert Christopher , da Motta Veiga Serge P. 
Published: August 2017

AbstractThis study examined whether everyday conversational humor is related to job satisfaction, and if the relationship is mediated by positive affect. We also explored differences between the roles of humor production and humor appreciation, and tested the cyclical nature of the relationship by examining whether job satisfaction stimulates subsequent humor. Data were obtained through an experience sampling study in which participants completed two brief surveys each day for 10 consecutive workdays (Level 1 n=237–279, Level 2 N=35). Results revealed a positive relationship between humor and job satisfaction that was partially mediated by positive affect, and also indicated that job satisfaction on day
Surface Characterization of Sulfated Iron Oxide and Its Synthesis of Biodiesel Under Microwave Radiation

Published: August 2017

AbstractThe solid acid catalysts SO42−/Fe2O3were prepared by impregnation technique, and the preparation conditions were different in calcination temperature, concentration of impregnation solution of H2SO4and impregnation time. The characterization was performed by using Fourier transform infrared spectrometer (FTIR), X-ray diffraction (XRD), Temperature programed desorption of NH3(NH3‒TPD), N2‒BET and microwave absorbing test. As shown by FTIR spectra, the S=O functional group existed in the sample, which was essential for the strong acidity of the SO42‒/MxOytype solid acids. The XRD results indicated that when the calcination temperature exceeded 400℃, iron in SO42‒/Fe2O3transformed from amorphous to crystalline phase. The results from NH3-TPD showed that the prepared sample possessed strong acid and superacid sites. As shown by N2-BET results, the BET surface area of the samples was up to 200m2/g, and their pore size distributions essentially belonged to mesoporous characteristic distribution. The SO42−/Fe2O3solid acid catalysts were used for the transesterification of castor oil under microwave radiation to produce biodiesel. The amounts of FAME in the product were analyzed by high-performance liquid chromatography. The highest yield of product was 65.3 wt.% when the reaction temperature was 65 ℃, alcohol/oil molar ratio was 30/1, catalyst loading was 20 wt.%, the reaction time was 3 h and the power of microwave was 300 w. Furthermore, the reaction results showed that SO42‒/Fe2O3had better catalytic activity under microwave radiation than under conventional heating condition.
Modified Teaching-Learning-Based Optimization for Combined Heat and Power Economic Dispatch
Authors: Pattanaik Jagat Kishore , Basu Mousumi , Dash Deba Prasad 
Published: August 2017

AbstractThis paper develops and suggests modified teaching-learning-based optimization to solve non-smooth non-convex combined heat and power economic dispatch (CHPED) problem. The valve-point loading and forbidden working regions of conventional thermal generator are taken into account. Modified teaching–learning-based optimization (MTLBO) introduces Gaussian random variables in the ‘Teacher phase’ and ‘Learner phase’ which perks up search efficiency and assurances a high probability of acquiring the global optimum without considerably impairing the convergence speed and the simplicity of the structure of teaching-learning-based optimization (TLBO). The efficacy of the suggested MTLBO technique has been confirmed on three test systems and 15 benchmark functions. Test results of the suggested technique have been matched up to those achieved by other evolutionary techniques. It has been observed from the comparison that the suggested MTLBO technique has the ability to endow with superior solution.
Two Time Steps Predictive Control Application to a Bioprocess Simulator
Authors: Altuntaş Semin , Hapoglu Hale 
Published: August 2017

Abstract
The control of batch bioreactors to maintain the pH at a constant set point is quite different from the continuous system applications, because acid and base simultaneous addition has a strong effect on the closed-loop performance which may never reach the desired value. While it is most desirable to use approximate models based on the chemistry of the system, this may not always be possible for batch bioprocesses. The present paper discusses the usage of a simulator with appropriate input and output data obtained from the real batch bioprocess without control. The real process pH behaviour was simulated by using 7 M citric acid flow rate changes in the face of constant base addition. Two time steps predictive control was applied to the bioprocess simulator by coordinating 0.5 M citric acid and 0.5 M sodium bicarbonate flow rates. The best control weighting factor magnitude was determined. The control was achieved successfully for regulator problem.
Language is me: Language maintenance in Chipilo, Mexico
Authors: Tararova Olga 
Published: August 2017

AbstractThe present study analyses the attitudes of Italo-Mexican speakers in a bicultural, bilingual community, Chipilo, Mexico, who have preserved their minority language, Veneto, for over a century. The study was guided by two research questions, which examined the possible instruction in Veneto in schools and the link between speakers’ identity and Veneto. Three social variables were examined: gender, age, and education. The results showed a positive correlation between participants’ identity and Veneto use, specifically among younger male speakers. In terms of instruction in schools, the data revealed the possibility of incorporating Veneto in classrooms; predominantly positive responses were given among males (aged 35–55+) with College and University levels of education. Based on these two results, there is a high probability of Veneto maintenance in the near future.
Rap music in minority languages in secondary education: A case study of Catalan rap
Authors: Aliagas Marín Cristina 
Published: August 2017

AbstractThis article explores hip hop music as a powerful tool for educational institutions to promote minority languages among teenagers living in multilingual contexts. It reports on an educational experience in secondary education that consisted of a series of rhyme workshops given by a guest hip hop artist in a secondary school in Catalonia, where two main languages (Spanish and Catalan) coexist in an unbalanced situation that favours Spanish for peer-communication. Drawing on two articulated pieces of fieldwork (the first one in the classroom and the second outside school with three students who were emergent rappers), the study shows a rift between language practices in the classroom and hip hop language practices in the teenagers’ lives. It also shows the powerful effect of bringing a professional musician into the classroom and how the school can have an impact on the language practices of the students outside school.
The Prosser Letters: Scholar as Dean
Authors: Robinette Christopher J. , Graham Kyle 
Published: August 2017

Abstract
Examining a previously unexplored trove of letters, this article sheds new light on the thinking and work of William L. Prosser, the past century’s leading torts scholar. In these letters to family written while dean of the University of California, Berkeley School of Law, Prosser candidly describes his approach to scholarship; the development of his casebook, the second edition of Prosser on Torts, and some of his most well-known and influential articles. Moreover, Prosser provides his often-cynical impressions of the legal process; his views of his peers at Berkeley and at other institutions; and his work as dean. The letters also demonstrate some of Prosser’s limitations, including his craving for attention, a sometimes petty personality, and racial and ethnic biases. In all, the letters capture a scholar at the zenith of professional accomplishment in his field, who nevertheless showed signs of the insecurity that would later trigger his resignation from the Berkeley deanship and retreat from the forefront of torts scholarship.
The Chow-Lin method extended to dynamic models with autocorrelated residuals
Authors: Poissonnier Aurélien 
Published: August 2017

Abstract
I provide a closed-form solution to temporal disaggregation or interpolation models which is both general in terms of dynamic structure of the model (lags of the high-frequency variable) and flexible in terms of autocorrelation of its residual. As for static models, I show that assuming autocorrelated residuals in dynamic models is practically convenient. To illustrate the potential of the solution proposed, I provide an example for quarterly non-financial corporations’ capital stock in computers and communication equipment.
Semantic values as latent parameters: Testing a fixed threshold hypothesis for cardinal readings of few & many
Authors: Schöller Anthea , Franke Michael 
Published: August 2017

Abstract
Certain uses of vague quantifiers few and many intuitively compare a true quantity to a priori expectations about that quantity. A concrete proposal for the truth conditions of such readings stipulates a contextually-stable threshold on a contextually-variable representation of a priori expectations (Clark, H. H. 1991. Words, the world, and their possibilities. In Lockhead G. R. & Pomerantz J. R. (eds.), The perception of structure: Essays in honor of Wendell R Garner, 263–277. Washington, DC: American Psychological Association; Fernando, T. & H. Kamp. 1996. Expecting many. In Galloway T. & Spence J. (eds.), Proceedings of SALT VI, 53–68. Ithaca, NY: Cornell University.) The main goal of this paper is to introduce data-driven computational modeling as a means to implement and test complex semantic theories of this kind, which may be hard to assess based on solitary introspection of meaning intuitions. Based on an empirical measure of a priori expectations, we use Bayesian inference to estimate likely values of the latent threshold parameters given empirical data from production and comprehension tasks. We demonstrate how posterior inference and statistical model comparison can help assess the plausibility of the fixed threshold hypothesis.
