Entire Large Solutions to Elliptic Equations of Power Non-linearities with Variable Exponents
Authors: Lair Alan V. , Mohammed Ahmed 
Published: March 2016

Abstract
We give conditions on the variable exponent q that ensure the existence and nonexistence of a positive solution to the elliptic equation Δu = uq(x) on ℝN (N ≥ 3) which satisfies lim|x|→∞ u(x) = ∞. The nonnegative function q is required to be locally Hölder continuous on ℝN. We prove existence for q > 1 provided q(x) decays to unity rapidly as |x| → ∞. We treat the case q ≤ 1 as a special case of q − 1 changing signs and show that a solution exists provided q is asymptotically radial. In addition, we give an example to show that our results are nearly optimal.
Some Results on Weak KAM Theory for Time-periodic Tonelli Lagrangian Systems
Authors: Wang Kaizhi , Li Yong 
Published: March 2016

Abstract
This paper contributes several results on weak KAM theory for time-periodic Tonelli Lagrangian systems. Wang and Yan [Commun. Math. Phys. 309 (2012), 663-691] introduced a new kind of Lax-Oleinik type operator associated with any time-periodic Tonelli Lagrangian. Firstly, using the new operator we give an equivalent definition of the backward weak KAM solution. Then we prove a result on the asymptotic behavior of the new operators with an arbitrary continuous function as initial condition, by taking advantage of the definition mentioned above. Finally, for a specific class of time-periodic Tonelli Lagrangians, we discuss the rate of convergence of the new operators.

Solutions with Polynomial Growth to an Autonomous Nonlinear Elliptic Problem
Authors: Wei Juncheng , Wang Kelei 
Published: March 2016

Abstract
We study the nonlinear elliptic problem
-Δu = Fʹ (u) in ℝn

where F(u) is a periodic function. Moser (1986) showed that for any minimal and nonself-intersecting solution, there exist α ∈ ℝn and C > 0 such that
(*) |u - α · x| ≤ C.
He also showed the existence of solutions with any prescribed α ∈ ℝn. In this note, we first prove that an solution satisfying (*) with nonzero vector α must be one dimensional. Then we show that in ℝ2, for any positive integer d ≥ 1 there exists a solution with polynomial growth |x|d.
Design of mechatronic systems through aspect and object-oriented modeling
Authors: Barbieri Giacomo , Derler Patricia , Auslander David M. , Borsari Roberto , Fantuzzi Cesare 
Published: March 2016

Abstract
Design of mechatronic systems involves the use of multiple disciplines, from mechanics to electronics and computer
science. Different granularities of hybrid co-simulations with increasing details can be used during the design process. However, there
is the need of modeling tools for effectively managing the necessary abstraction layers. This work proposes a combination of
Aspect-Oriented and Object-Oriented modeling for reaching the goal. Moreover, it shows how the utilization of these tools can
facilitate design-space exploration, segregation of domains of expertise and enhances co-design.
Automatic test case generation from requirements for industrial cyber-physical systems
Authors: Sinha Roopak , Pang Cheng , Martínez Gerardo Santillán , Vyatkin Valeriy 
Published: March 2016

Abstract
Industrial cyber-physical systems require complex software to orchestrate heterogeneous mechatronic components and control physical
processes. This software is typically developed and refined iteratively in a model-driven fashion. Testing such multi-dimensional
systems is extremely difficult as subsequent refinements may not correspond accurately with previous system models.
We propose a framework to generate test-cases from functional requirements at all stages in the model-driven engineering process.
A requirements ontology initially created during requirements engineering is iteratively refined such that test-cases can be generated
automatically. An industrial water process system case study illustrates the strengths of the proposed formalism. We also present an
automatic test-case generation and execution tool called REBATE (REquirements Based Automatic Testing Engine).
Bregman superquantiles. Estimation methods
and applications
Authors: Labopin-Richard T. , Gamboa F. , Garivier A. , Iooss B. 
Published: March 2016

Abstract
In thiswork,we extend some parameters built on a probability distribution introduced before to the
casewhere the proximity between real numbers is measured by using a Bregman divergence. This leads to the
definition of the Bregman superquantile (thatwe can connect with severalworks in economy, see for example
[18] or [9]). Axioms of a coherent measure of risk discussed previously (see [31] or [3]) are studied in the case
of Bregman superquantile. Furthermore,we deal with asymptotic properties of aMonte Carlo estimator of the
Bregman superquantile. Several numerical tests confirm the theoretical results and an application illustrates
the potential interests of the Bregman superquantile.
Facing face: non-professional interpreting in prison mental health interviews
Authors: Martínez-Gómez Aída 
Published: March 2016

AbstractFace, or the public self-image that each individual claims for him-/herself, is continuously constructed and negotiated in interaction. In interpreter-mediated events, the interpreter’s actions may threaten, maintain or enhance the primary participants’ face, as well as their own. This single case study of a real-life interview between a prison psychologist and a foreign language-speaking inmate, interpreted by another inmate, aims to explore how and why the three members of the triad engage in face-threatening acts (Brown and Levinson 1987) and face-boosting acts (Bayraktaroglu 1991). The transcribed audio recording of the interview shows how this non-professional interpreter actively seeks to protect and improve his fellow prisoner’s face, as a potential expression of his in-group loyalty, but ultimately prioritizes his own social image in an attempt to present himself as cooperative and trustworthy before the psychologist. This analysis shows how underlying issues of social distance, power and trust forcefully shape conversational behaviors in the prison environment.
Isotherms and kinetic studies on adsorption of Hg(II) ions onto Ziziphus spina-christi L. from aqueous solutions
Authors: Hashem Ali , Al-Anwar Alaauddin , Nagy Negma M. , Hussein Doaa M. , Eisa Sara 
Published: March 2016

AbstractL. (ZscL) is a plant residue that has been used as adsorbent for the removal of Hg(II) ions from an aqueous solution. The ability of ZscL to adsorb Hg(II) ions was investigated by using the batch adsorption procedure. It was characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) to support the adsorption of Hg(II) ions. The effects of various parameters on the adsorption process, such as contact time, adsorbent concentration, solution pH and initial concentrations of metal ions were studied to optimize the conditions for maximum adsorption. Experimental equilibrium data were fitted to the Freundlich, Langmuir, Dubinin-Radushkevich, Halsey and Temkin (two parameter models), Redlich-Peterson, Sips, Khan, Hill, Radke-Prausnitz, Langmuir-Freundlich and Toth (three parameter models), Fritz-Schlunder and Baudu (four parameter models) and Fritz-Schlunder (five parameter model) at 30°C by using nonlinear regression analysis. The examination of error analysis methods showed that the Halsey model provides the best fit for experimental data compared with the other isotherms. Various kinetic models have been applied to the experimental data to predict the adsorption kinetics. It was found that pseudo-second-order rate was better obeyed than pseudo-first-order reaction, supporting that the chemisorption process was involved. The obtained results show that ZscL can be used as an effective and natural low-cost adsorbent for the removal of Hg(II) ions from aqueous solutions.
The physiology of functional hypothalamic amenorrhea associated with energy deficiency in exercising women and in women with anorexia nervosa
Authors: Allaway Heather C.M. , Southmayd Emily A. , De Souza Mary Jane 
Published: March 2016

Abstract
An energy deficiency is the result of inadequate energy intake relative to high energy expenditure. Often observed with the development of an energy deficiency is a high drive for thinness, dietary restraint, and weight and shape concerns in association with eating behaviors. At a basic physiologic level, a chronic energy deficiency promotes compensatory mechanisms to conserve fuel for vital physiologic function. Alterations have been documented in resting energy expenditure (REE) and metabolic hormones. Observed metabolic alterations include nutritionally acquired growth hormone resistance and reduced insulin-like growth factor-1 (IGF-1) concentrations; hypercortisolemia; increased ghrelin, peptide YY, and adiponectin; and decreased leptin, triiodothyronine, and kisspeptin. The cumulative effect of the energetic and metabolic alterations is a suppression of the hypothalamic-pituitary-ovarian axis. Gonadotropin releasing hormone secretion is decreased with consequent suppression of luteinizing hormone and follicle stimulating hormone release. Alterations in hypothalamic-pituitary secretion alters the production of estrogen and progesterone resulting in subclinical or clinical menstrual dysfunction.
A link between hypothyroidism, obesity and male reproduction
Authors: Aiceles Veronica , da Fonte Ramos Cristiane 
Published: March 2016

Abstract
Hypothyroidism is a condition in which the serum levels of thyroid hormones are below that necessary to carry out physiological functions in the body. Hypothyroidism is related to obesity as an increase in body weight gain is seen in hypothyroid patients. Moreover, an inverse correlation between free thyroxine values and body mass index has been reported. Leptin, a polypeptide hormone produced by adipocytes, was originally thought to be an antiobesity hormone due its anorexic effects on hypothalamic appetite regulation. However, nowadays it is known that leptin conveys information about the nutritional status to the brain being considered a crucial endocrine factor for regulating several physiological processes including reproduction. Since the identification of thyroid hormone and leptin receptors on the testes, these hormones are being recognized as having important roles in male reproductive functions. A clear link exists among thyroid hormones, leptin and reproduction. Both hormones can negatively affect spermatogenesis and consequently may cause male infertility. The World Health Organization (WHO) estimates the overall prevalence of primary infertility ranging from 8 to 15%. The fact that 30% of couples’ inability to conceive is related to a male factor and that the longer hypothyroidism persisted, the greater the damage to the testes, strongly suggest that more studies attempting to clarify both hormones actions directly in the testes need to be conducted specially in cases of congenital hypothyroidism. Therefore, the goal of this review is to highlight the relationship of such hormones in the reproductive system.

Published: March 2016

Abstract
Endometrial cancer (EC) is the commonest gynaecological cancer in the Western World with an alarmingly increasing incidence related to longevity and obesity. Ovarian hormones regulate normal human endometrial cell proliferation, regeneration and function therefore are implicated in endometrial carcinogenesis directly or via influencing other hormones and metabolic pathways. Although the role of unopposed oestrogen in the pathogenesis of EC has received considerable attention, the emerging role of other hormones in this process, such as androgens and gonadotropin-releasing hormones (GnRH) is less well recognised. This review aims to consolidate the current knowledge of the involvement of the three main endogenous ovarian hormones (oestrogens, progesterone and androgens) as well as the other hormones in endometrial carcinogenesis, to identify important avenues for future research.

Published: March 2016

Abstract
The hydrological characteristics and the rate of organic matter supply from coastal lagoons help to understand their responses to nutrient input by anthropogenic and natural sources. The aim of this study was to determine the hydrologic and trophic status of the El Rancho-Empalme lagoon system in a semiarid region in the Gulf of California, Mexico. This lagoon system consists of two geomorphological subsystems which are affected by nutrient inputs from shrimp farm effluents and coastal upwelling. Sampling was conducted over the course of one year and included measurements of temperature, salinity, and dissolved oxygen, surface water grab samples to analyze nitrite, nitrate, ammonia, orthophosphate, and chlorophyll a. The trophic status was assessed using the TRophic IndeX (TRIX). The subsystems El Rancho and Empalme had a similar hydrological behavior throughout the year, reflecting a good exchange of water, materials and energy. The TRIX index showed oligotrophic state during spring, summer and autumn, and a mesotrophic state in winter. Nutrient inputs from shrimp farm effluents were not responsible for trophic status increases, however, coastal upwelling in the region plays an important role in the growing rate of seasonal supply of organic matter to these coastal lagoons.
Artificial hard substrate as a habitat for hard bottom benthic assemblages in the southern part of the Baltic Sea – a preliminary study
Authors: Brzana Radosław , Janas Urszula 
Published: March 2016

Abstract
Benthic species associated with hard substrate are known to form communities characterized by high abundance and biomass. Although the bottom of the Southern Baltic Sea is dominated by soft sediments, such communities find favorable conditions to thrive on artificial substrates of offshore constructions. The aim of this research was to characterize both short-term and long-term benthic communities associated with artificial hard bottom provided by man-made structures in the Southern Baltic Sea. Species composition as well as the abundance and biomass were examined at various sites. An inactive World War II torpedo testing facility in the Gulf of Gdansk served as a site for sampling long-term communities while short-term communities were sampled using settlement panels and PVC cylinders. Panels were deployed at the torpedo testing facility for 127 days. PVC cylinders were deployed for 141-190 days in the Polish Exclusive Economic Zone. Twenty six macrofaunal taxa, including 12 crustaceans, were identified during the research. Mytilus edulis and Amphibalanus improvisus were the most abundant invertebrates at sampled surfaces. Six non-indigenous species were found. For the first time adult individuals of Mytilopsis leucophaeata were found in the Polish Marine Areas indicating that it is possible for this non-indigenous species to reproduce in this region.
Postural instability and falls in Parkinson’s disease
Authors: Crouse Jacob J. , Phillips Joseph R. , Jahanshahi Marjan , Moustafa Ahmed A. 
Published: March 2016

AbstractPostural instability (PI) is one of the most debilitating motor symptoms of Parkinson’s disease (PD), as it is associated with an increased risk of falls and subsequent medical complications (e.g. fractures), fear of falling, decreased mobility, self-restricted physical activity, social isolation, and decreased quality of life. The pathophysiological mechanisms underlying PI in PD remain elusive. This short review provides a critical summary of the literature on PI in PD, covering the clinical features, the neural and cognitive substrates, and the effects of dopaminergic medications and deep brain stimulation. The delayed effect of dopaminergic medication combined with the success of extrastriatal deep brain stimulation suggests that PI involves neurotransmitter systems other than dopamine and brain regions extending beyond the basal ganglia, further challenging the traditional view of PD as a predominantly single-system neurodegenerative disease.
Narrating the Contested Space of Detroit’s River Rouge, 1600–2015
Authors: Nye David E. 
Published: March 2016

Abstract
The River Rouge, which flows through Michigan into the Great Lakes at Detroit, has been a contested space, from the Mound Builders c. 1100 AD to the present. The river’s changing uses and meanings provide a microcosm of North American history, including Native Americans, French fur traders, the British, American settlers, small-scale industries, and Henry Ford’s largest factory. Narratives treat the river as a landscape, as a highway, as a natural resource, as raw material, as a minor detail, or as a threatened environment. The river has been part of a romantic view of pre-history, a heroic story of colonial conquest, a tale of democratic expansion into new land, an exemplary second creation in which unfinished nature is transformed into the world’s largest factory, a narrative of class warfare between workers and capitalists, a tale of the triumph of democracy over National Socialism in World War II, a tragic story of the exploitation of nature, and a recovery narrative in which the river is rescued from pollution and misuse.
“The Americans are Rumored to be Eccentrics”: On Los Angeles through the Romanian Cultural Lens
Authors: Lolea Georgiana 
Published: March 2016

AbstractMy essay brings into focus the ways in which Petru Comarnescu – the first Romanian Americanist – depicted the Los Angeles of the late 1920s, and it shows that his cultural encounter triggered both processes of representation and of misrepresentation, giving rise to varying cultural constructions of place. This is tied to the fact that making the new and unfamiliar meaningful presupposes a continuous process of ‘translation’ laden with approximations, misconceptions, distortions, half-truths, and varying authenticities. When Comarnescu sought to pin down otherness, it was the familiar which resurfaced, and the cultural heritage of the place left behind ‘taught’ the traveler what and how to see. In doing so, travel writings could best exemplify that cultural boundaries are fluid and permanently drawn and redefined.
Neutron powder diffraction and theory-aided structure refinement of rubidium and cesium ureate

Published: March 2016

Abstract
Urea (CN2H4O) is a fundamental biomolecule whose derivatives are abundant throughout chemistry. Among the latter, rubidium ureate (RbCN2H3O) and its cesium analog (CsCN2H3O) have been described only very recently and form the first structurally characterized salts of deprotonated urea. Here, we report on a neutron diffraction study on the aforementioned alkaline-metal ureates, which affords the positions for all hydrogen atoms (including full anisotropic displacement tensors) and thus allows us to gain fundamental insights into the hydrogen-bonding networks in the title compounds. The structure refinements of the experimental neutron data proceeded successfully using starting parameters from ab initio simulations of atomic positions and anisotropic displacement parameters. Such joint experimental-theoretical refinement procedures promise significant practical potential in cases where complex solids (organic, organometallic, framework materials) are studied by powder diffraction.

Abstract
With the advent of third-generation synchrotron sources and the
development of light source techniques, X-ray scattering techniques
have become feasible, leading to new approaches for studying the
structures of disordered materials in a quantitative manner. We
introduce a dedicated diffractometer for high-energy total X-ray
scattering measurement and a newly developed anomalous X-ray
spectrometer at SPring-8. As advanced methodologies for the
measurement of liquids, we now offer three state-of-art levitation
instruments for aerodynamic levitation, electrostatic levitation, and
acoustic levitation at the SPring-8 beamlines, covering a wide
temperature range of −40–3000 ℃. Furthermore,
scientific investigations of glasses, liquids, and amorphous materials
reported in the last five years at SPring-8 are reviewed.
A Comparison of Structural Models of Tb3Al5O12 and Nd3Al5O12 Glasses Obtained When Using X-ray Data Alone and When X-ray and Neutron Data are Combined
Authors: Barnes Adrian 
Published: March 2016

Abstract
X-ray diffraction experiments, including Anomalous X-ray Diffraction,
have been carried out on Tb3Al5O12 and
Nd3Al5O12 glasses. In addition, neutron diffraction
and isotopic substitution experiments have been carried out for
Nd3Al5O12. The data has been analysed by direct
Fourier transform methods and by refinement of atomistic structures
obtained from Molecular Dynamics simulations. For
Nd3Al5O12 good agreement between the Molecular
Dynamics simulations and all the experimental data was obtained. The
Molecular Dynamics configuration was refined further using Reverse
Monte Carlo methods to obtain a final atomistic configuration. The
Nd3Al5O12 Molecular Dynamics configuration was refined
using the X-ray data alone and the results show that the final
configuration was in worse agreement with the data than the original
Molecular Dynamics calculation. From this result it was concluded that
in order to obtain a good atomistic model of Tb3Al5O12
it is essential to include at least one neutron diffraction
measurement in the Molecular Dynamics – Reverse Monte Carlo
refinement.
