Descomunicar la pobreza: un análisis filosófico (genealógico) sobre las formas de transmisión de la pobreza y la desigualdad
Authors: DEL PRADO FLORES Rogelio
Published: October 2018

En el presente texto analizamos tres enfoques sobre la pobreza que son importantes en épocas diferentes. En las comunidades cristianas de los primeros siglos, es enunciado una perspectiva que representa un giro con respecto a la filosofía antigua. La nueva perspectiva implica la integración de las comunidades en un proyecto que transciende las expectativas individuales. Aquí se examinan algunos textos de pensadores cristianos que son la base para la unidad de las comunidades. Este proyecto dejó de ser hegemónico tras los acontecimientos que dieron origen al pensamiento anglosajón. Analizamos en particular el Segundo tratado sobre el gobierno civil de John Locke porque es un texto fundacional en el pensamiento liberal europeo. Destacamos el individualismo posesivo, así como la introducción del dinero dentro del experimento mental llamado estado de naturaleza original como relación que incrementa la desigualdad. La construcción lockeana del secularismo y del individualismo metodológico tiene gran relevancia para la defensa de los derechos humanos. Sin embargo, también representa un fuerte competidor con el enfoque cristiano. El liberalismo político contemporáneo es el tercer enfoque que abordamos para analizar el concepto de pobreza. Esta perspectiva liberal es el cimiento de las políticas públicas que combate la pobreza. Aunque las mediciones son exhaustivas, esta forma de acotar la problemática no integra el saber de las personas que viven en situación de pobreza en el diseño de políticas de vida que atiendan de raíz las consecuencias que originan la pobreza.

Background: The nephrotic syndrome (NS) resistance and relapse to treatment pose challenges in the management of NS. Several experimental studies on both animals and humans have assessed the association between NS and the balance between the oxidants and anti-oxidants. The study aims to compare the status of oxidants and anti-oxidants of NS patients between the massive proteinuria, the remission, the steroid resistance and the control groups.

Methods:  a cross-sectional design to assess the status of oxidants and antioxidants in children with the nephrotic syndrome. The eligible subjects were divided into four groups, the massive proteinuria group, the remission group, the steroid resistant group and the control group. The status of oxidants and anti-oxidant were evaluated with the Malondialdehyde (MDA) and the Total Antioxidant Status (TAS), respectively.

Results: The highest mean MDA levels was observed in the steroid resistant group followed by the massive proteinuria group and the remission group. The mean MDA level of the proteinuria group (massive proteinuria and steroid-resistant) is higher than the remission group. The mean TAS levels in the remission group were higher than the massive proteinuria group, but the difference was not statistically significant. Moreover, the mean difference of SAT between the proteinuria group and without proteinuria was not statistically significant.

Conclusions: The oxidative stress marker (MDA) was higher in the NS patients with proteinuria than the patients without proteinuria. The difference in the total anti-oxidant status in NS patients with massive proteinuria, remission and steroid resistance were not statistically significant.

The current article, based on field work from 2004 to 2016, examines the present condition of the sites described in 1972, offers a revised analysis of their significance, and introduces newly discovered rock art that connects Wakhan with the Saka culture of Central Asia and illustrates indigenous traditions of the Pamir-Hindukush ethnolinguistic region.
Scale, Deep Time, and the Politics of Representation in Derek Mahon's Life on Earth
Authors: Flannery Eoin
Published: October 2018

This essay reads Derek Mahon's 2008 collection, Life on Earth, in broadly ecocritical terms, arguing that the ecological concentrations of Mahon's recent work centre on the representational relationships between human and non-human ecologies; on matters of ecological belonging and placelessness, in local and international contexts; as well as probing the ethics of anthropocentric historical narration in terms of geological time and the ‘deep’ past. Furthermore, the argument focuses on the poet's attention to scalar relations in time and space and how they relate to anthropogenic climate change. It also highlights Mahon's recourse to ekphrasis in his meditation upon the politics and ethics of aesthetic representation in the context of global environmental destruction.
Towards an Oceanic Dubliners
Authors: Pearson Nels
Published: October 2018

Oceanic Studies sheds a compelling new light on James Joyce's Dubliners. Although they are citizens of a major imperial port city living amidst a global flow of goods, cultures, and ideas, Joyce's characters are n also impeded from reciprocal engagement in this circuitry. From Eveline, who stands paralyzed at the docks by the North Wall as ‘all the seas of the world tumble about her heart’, to the boys of ‘An Encounter’, who marvel at tall ships but are imprisoned by social dichotomies, to Jimmy Doyle's ill-fated efforts at cosmopolitanism on board an American yacht, to the latent Gaeltacht musings of Gabriel Conroy, a would-be European son of a Dublin Port and Docks board member, Joyce uses water to help identify a persistent desynchronization of national and global Ireland.

Study of Disinfectant Resistance Genes in Ocular Isolates of Pseudomonas aeruginosa
Authors: Subedi Dinesh , Vijay Ajay Kumar , Willcox Mark
Published: October 2018

Background: The prevalence of disinfectant resistance in Pseudomonas aeruginosa is on the rise. P. aeruginosa is the most common bacteria isolated from cases of microbial keratitis. Many multi-purpose contact lens disinfectant solutions are available to decontaminate contact lenses before use and to help reduce the incidence of infections. However, with increasing disinfectant resistance, the effect of multi-purpose disinfectant solutions may diminish. The goal of this study was to examine genes associated with disinfectant resistance in ocular isolates of P. aeruginosa and understand the strain’s susceptibility to different multipurpose disinfectant solutions. Methods: Seven potential disinfectant resistance genes were used in BLASTn searches against the whole genomes of 13 eye isolates of P. aeruginosa. A microdilution broth method was used to examine susceptibility to four different multipurpose disinfectant solutions. Results: All strains possessed the sugE2, sugE3 and emrE (qacE) genes. The sugE1 and qacEdelta1 genes were present in 6/13 isolates. No strains contained the qacF or qacG genes. All tested disinfectant solutions had the ability to kill all test strains at 100% concentration, with some strains being susceptible at 1:8 dilutions of the disinfecting solutions. However, the presence of disinfectant resistance genes was not associated with susceptibility to multi-purpose disinfectants. Conclusion: All four tested contact lens disinfectant preparations are effective against P. aeruginosa isolates regardless of the presence of disinfectant resistance genes.
Extraction Optimization of Phenolics and Antioxidants from Black Goji Berry by Accelerated Solvent Extractor Using Response Surface Methodology
Authors: He Qinghua , Du Bin , Xu Baojun
Published: October 2018

This study aims to provide fundamental knowledge for the use of black goji berry and determine the optimum process parameters that produce maximum phenolics from black goji berry through accelerated solvent extraction (ASE). The optimal extractions of phenolics and antioxidants from black goji were explored via the ASE techniques, applying the response surface methodology (RSM) design. After reaching the optimal conditions for single factors, the optimal ASE extraction conditions were found through a total of 17 runs following the Box-Behnken design (BBD) from RSM. The maximum yield of total phenolic content (TPC) was 17.92 mg GAE/g under the best extraction conditions: an extraction temperature of 89.38 °C, an ethanol concentration of 70% and an extraction time of 13 min. This study indicates that the optimal extraction conditions could serve as the scientific basis for scaled-up industrial production. Black goji berry could be a viable source of nutraceuticals due to the abundance of antioxidant and phenolic substances.
Interference-Aware Cooperative Anti-Jamming Distributed Channel Selection in UAV Communication Networks
Authors: Xu Yifan , Ren Guochun , Chen Jin , Zhang Xiaobo , Jia Luliang , Kong Lijun
Published: October 2018

This paper investigates the cooperative anti-jamming distributed channel selection problem in UAV communication networks. Considering the existence of malicious jamming and co-channel interference, we design an interference-aware cooperative anti-jamming scheme for the purpose of maximizing users’ utilities. Moreover, the channel switching cost and cooperation cost are introduced, which have a great impact on users’ utilities. Users in the UAV group sense the co-channel interference signal energy to judge whether they are influenced by co-channel interference. When the received co-channel interference signal energy is lower than the co-channel interference threshold, users conduct channel selection strategies independently. Otherwise, users cooperate with each other and take joint actions with a cooperative anti-jamming pattern under the impact of co-channel interference. Aiming at the independent anti-jamming channel selection problem under no co-channel interference, a Markov decision process framework is introduced, whereas for the cooperative anti-jamming channel selection case under the influence of co-channel mutual interference, a Markov game framework is employed. Furthermore, motivated by Q-learning with a “cooperation-decision-feedback-adjustment” idea, we design an interference-aware cooperative anti-jamming distributed channel selection algorithm (ICADCSA) to obtain the optimal anti-jamming channel strategies for users in a distributed way. In addition, a discussion on the quick decision for UAVs is conducted. Finally, simulation results show that the proposed algorithm converges to a stable solution with which the UAV group can avoid malicious jamming, as well as co-channel interference effectively and can realize a quick decision in high mobility UAV communication networks.

Changes in the humidity of different bays and the relationship between local humidity and local temperature were investigated. Moreover, the concept as well as a method of calculating the humidity characteristic coefficient (HCC) were put forward, and two models of aircraft local humidity were established using the humidity and temperature of the thermometer shelter as arguments. Furthermore, bays of an airplane were divided into three groups according to differences in local humidity, and the range of the HCC of each group were determined. The results suggest that the rates of change of local humidity and local temperature are negatively correlated, moreover, the theoretical model shows a linear relationship between humidity and temperature, with a negative slope suggesting changes in humidity are inversely proportional to temperature. The ratio of the local environment slope to the external environment slope has a constant value. Finally, bay sealing and temperature features were found to significantly affect local humidity, and average deviations between the monitored humidity and humidity values predicted using the two temperature models were all less than, or equal to, 7.3% relative humidity.

This study examines the decadal change in the relationship between two major Indian Ocean (IO) sea surface temperature patterns, namely the Indian Ocean dipole (IOD) and northern IO and the East Asia summer monsoon (EASM) in the early 2000s. In 1991–1999, the former epoch, the interannual variability of EASM was associated with the IOD-like pattern in the original paper and its relationship weakened in 2000–2016. There are two possible causes for this decadal change; stronger land-sea thermal contrast as a local forcing in latter epoch, which may result in the weakening of the relationship between the IO and the EASM. In addition, the influence of El Niño-southern Oscillation (ENSO) on the western North Pacific subtropical high (WNPSH) could be changed depending on the frequency of ENSO. In the 2000s, the intensity of the low frequency (LF)-type ENSO (42–86 months period) events was weaker compared to the former epoch but that of quasi-biennial (QB)-type ENSO (16–36 months period) remained persistent. This could explain that the QB-type ENSO is remote forcing that modulates the change in the relationship between the tropical IO patterns and EASM in the 2000s.

A simple tailor-made protocol to synthesize graphene-based magnetic nanoparticles (GbMNPs) for nanomedicine is herein reported. Different GbMNPs with very distinctive physicochemical and toxicological properties were synthesized by adjusting the number of carbon precursors in the coating of superparamagnetic iron oxide nanoparticles. In vitro tests show the ability to use these GbMNPs as intelligent and on-demand drug nanocarrier systems for drug delivery, exhibiting the following features: good colloidal stability, good loading capacity of the chemotherapeutic drug doxorubicin, high pH-controlled release of the encapsulated drug (targeting tumour acidic pH conditions), superparamagnetic behaviour and biocompatibility. Due to their combined properties (i.e., physicochemical, magnetic, and biocompatibility), GbMNPs show high potentiality to be combined with other biomedical techniques, such as magnetic hyperthermia, which can represent an enhancement in the treatment of cancer.

Extracellular vesicles (EVs) are membrane enclosed micro- and nano-sized vesicles that are secreted from almost every species, ranging from prokaryotes to eukaryotes, and from almost every cell type studied so far. EVs contain repertoire of bioactive molecules such as proteins (including enzymes and transcriptional factors), lipids, carbohydrates and nucleic acids including DNA, coding and non-coding RNAs. The secreted EVs are taken up by neighboring cells where they release their content in recipient cells, or can sail through body fluids to reach distant organs. Since EVs transport bioactive cargo between cells, they have emerged as novel mediators of extra- and intercellular activities in local microenvironment and inter-organ communications distantly. Herein, we review the activities of EV-associated matrix-remodeling enzymes such as matrix metalloproteinases, heparanases, hyaluronidases, aggrecanases, and their regulators such as extracellular matrix metalloproteinase inducers and tissue inhibitors of metalloproteinases as novel means of matrix remodeling in physiological and pathological conditions. We discuss how such EVs act as novel mediators of extracellular matrix degradation to prepare a permissive environment for various pathological conditions such as cancer, cardiovascular diseases, arthritis and metabolic diseases. Additionally, the roles of EV-mediated matrix remodeling in tissue repair and their potential applications as organ therapies have been reviewed. Collectively, this knowledge could benefit the development of new approaches for tissue engineering.
Real-Time Determination of the Cell-Cycle Position of Individual Cells within Live Tumors Using FUCCI Cell-Cycle Imaging
Authors: Yano Shuya , Hoffman Robert M.
Published: October 2018

Most cytotoxic agents have limited efficacy for solid cancers. Cell-cycle phase analysis at the single-cell level in solid tumors has shown that the majority of cancer cells in tumors is not cycling and is therefore resistant to cytotoxic chemotherapy. Intravital cell-cycle imaging within tumors demonstrated the cell-cycle position and distribution of cancer cells within a tumor, and cell-cycle dynamics during chemotherapy. Understanding cell-cycle dynamics within tumors should provide important insights into novel treatment strategies.

Protein synthesis is at the core of bottom-up construction of artificial cellular mimics. Intriguingly, several reports have revealed that when a transcription–translation (TX–TL) kit is encapsulated inside lipid vesicles (or water-in-oil droplets), high between-vesicles diversity is observed in terms of protein synthesis rate and yield. Stochastic solute partition can be a major determinant of these observations. In order to verify that the variation of TX–TL components concentration brings about a variation of produced protein rate and yield, here we directly measure the performances of the ‘PURE system’ TX–TL kit variants. We report and share the kinetic traces of the enhanced Green Fluorescent Protein (eGFP) synthesis in bulk aqueous phase, for 27 combinatorial block-variants. The eGFP production is a sensitive function of TX–TL components concentration in the explored concentration range. Providing direct evidence that protein synthesis yield and rate actually mirror the TX–TL composition, this study supports the above-mentioned hypothesis on stochastic solute partition, without excluding, however, the contribution of other factors (e.g., inactivation of components).
A QUBO Formulation of the Stereo Matching Problem for D-Wave Quantum Annealers
Authors: Cruz-Santos William , Venegas-Andraca Salvador E. , Lanzagorta Marco
Published: October 2018

In this paper, we propose a methodology to solve the stereo matching problem through quantum annealing optimization. Our proposal takes advantage of the existing Min-Cut/Max-Flow network formulation of computer vision problems. Based on this network formulation, we construct a quadratic pseudo-Boolean function and then optimize it through the use of the D-Wave quantum annealing technology. Experimental validation using two kinds of stereo pair of images, random dot stereograms and gray-scale, shows that our methodology is effective.

As the EU is moving towards a low carbon economy and seeks to further develop its renewable energy policy, this paper quantitatively investigates the impact of plausible energy market reforms from the perspective of bio-renewables. Employing a state-of-the-art biobased variant of a computable general equilibrium model, this study assesses the perceived medium-term benefits, risks and trade-offs which arise from an advanced biofuels plan, two exploratory scenarios of a more ‘sustainable’ conventional biofuels plan and a ‘no-mandate’ scenario. Consistent with more recent studies, none of the scenarios considered present significant challenges to EU food-security or agricultural land usage. An illustrative advanced biofuels plan simulation requires non-trivial public support to implement whilst a degree of competition for biomass with (high-value) advanced biomass material industries is observed. On the other hand, it significantly alleviates land use pressures, whilst lignocellulose biomass prices are not expected to increase to unsustainable levels. Clearly, these observations are subject to assumptions on technological change, sustainable biomass limits, expected trends in fossil fuel prices and EU access to third-country trade. With these same caveats in mind, the switch to increased bioethanol production does not result in significant market tensions in biomass markets.
Performance Analysis of Air Cooled Heat Pump Coupled with Horizontal Air Ground Heat Exchanger in the Mediterranean Climate
Authors: Baglivo Cristina , Bonuso Sara , Congedo Paolo Maria
Published: October 2018

A concept of Air-Cooled Heat Pump (ACHP) coupled with a Horizontal Air-Ground Heat Exchanger (HAGHE), also called Horizontal Earth-To-Air Heat Exchanger (EAHX), has been proposed. The Air-Cooled Heat Pump is a system which transfers heat from outside source (air) to inside sink (water) and vice versa in summertime. The innovation is to provide a geothermal treatment of pre-heating/cooling of air before meeting the evaporator in winter or the condenser in summer of the heat pump. Besides, it is known that the variations of the ground temperature, respect to the external air one, are mitigated already in the first layers of the ground throughout the year, due to the high thermal inertia of the ground, letting the heat pump work with more mitigated conditions, improving the performances. The behaviour of HAGHE has been investigated by varying the length and the installation depth of the probes, the air flow rate and the ground thermal properties. All the combinations have been implemented using TRNSYS 17 software (Transient System Simulation Program) to obtain the outlet temperatures from HAGHE, resulting from the 54 configurations. The results are compared in terms of Coefficient of Performance (COP) in wintertime and Energy Efficiency Ratio (EER) in summertime between configurations with and without the coupling with HAGHE. In addition, two seasonal performance SCOP and SEER coefficients have been calculated considering, not only the inlet air temperatures into the Air-Cooled Heat Pump, but also their frequency of occurrence, the off-set external temperature (16 °C), the nominal external temperature and heating and cooling loads.
