Diario Perpetuo o el fuego constante de Aminur Rahman
Authors: Lovo Anastasio
Published: August 2013

Anastasio Lovo presenta la obra Diario Perpetuo de Aminur Rahman, poeta de Bangla Desh, interpretándola a la luz de las concepciones del amor que encontramos en la mística sufí: como un fluir permanente de creación. También establece una filiación con la dialéctica del todo y la nada hegelianos; más una genealogía poética derivada de la concepción del aire (Espíritu Santo), como enseña San Juan de la Cruz, el místico cristiano par excellence. Según Lovo los poemas de Rahman hablan del amor como un medio idóneo para conocer a Dios.

A multilaboratory study was conducted to determine the equivalence of the 3M™ Petrifilm™ Aerobic Count Plate and standard plating methodology for measuring viable bacteria and spores recovered from hard-surface carriers (stainless steel and porcelain), also known as "control carrier counts," used in AOAC antimicrobial efficacy test methods. Six laboratories participated in the study in which carriers inoculated with Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella enterica, and spores of Bacillus subtilis were evaluated using 3M Petrifilm Aerobic Count (AC) plates and standard plating side-by-side. The data were analyzed using a matched-pair t-test to determine the between-method effect with confidence intervals. For all test organisms pooled across all laboratories, the mean difference in log10 concentration between the standard plate count method and 3M Petrifilm AC Plates was −0.012, with a 95% confidence interval of (−0.090, +0.066), which was well within the −0.5, +0.5 interval established as the acceptance criterion. The between-carrier SD averaged 0.139; the between-replicate SD was 0.050. The carrier reproducibility, given that a single replicate per carrier is done, was estimated to be 0.148. Although differences were seen in the final concentrations of the test organisms among laboratories, there were no statistical differences between the enumeration methods. Based on the results from this study, 3M Petrifilm AC Plates are equivalent to standard plating methodology and can be used as an alternative procedure for the enumeration of test organisms used in AOAC Methods 955.14, 955.15, 964.02, and 966.04.
Tactical UAV Localization Using Coordinated Monopulse Trackers with Low Rate Feedback
Authors: An Chan-Ho , Yang Janghoon , Ran Rong , Pak Ui Young , Ryu Young-Jae , Kim Dong Ku
Published: August 2013

To run a tactical unmanned aerial vehicle (UAV), efficient information transmission schemes, such as beamforming, are preferred due to the limit of the payload. Therefore, beam tracking and localization algorithms are considered to be one of the key technologies. In this paper, we propose a coordinated UAV localization algorithm for a tactical scenario where the ground receivers are connected with wireless limited lower rate backhaul and are closely spaced. By applying the αβ filter to the conventional scheme, we first show that the localization performance can be improved significantly. We also propose an efficient localization algorithm for a system with low rate limited feedback. Using numerical simulations, we show that the proposed scheme can improve the localization performance while reducing the feedback over conventional scheme.
Micro Aerial Vehicle (MAV) Flapping Motion Control Using an Immune Network with Different Immune Factors
Authors: Weng Liguo , Xia Min , Hu Kai , Wang An
Published: August 2013

This paper proposes a novel Neural-Immunology/Memory Network to address the problem of motion control for flapping-wing Micro Aerial Vehicles (MAVs). This network is inspired by the human memory system as well as the immune system, and it is effective in attenuating the system errors and other lumped system uncertainties. In contrast to most existing Neural Networks, the convergence of this proposed Neural-Immunology/Memory Network can be theoretically proven. Both analyses and simulations that are based on different immune factors show that the proposed control method is effective in dealing with external disturbances, system nonlinearities, uncertainties and parameter variations.
Foraminifera from the Upper Cretaceous of northern James Ross Island (Antarctica): a preliminary report
Authors: Hradecká Lenka , Vodrážka Radek , Nývlt Daniel
Published: August 2013

The Cretaceous biostratigraphy of the James Ross Island region is generally based on palynomorphs and macrofossils (bivalves, ammonites). During geological mapping of the northern James Ross Island a number of samples from Upper Cretaceous lithologies were gathered to test the presence of foraminifers as a possible tool for stratigraphic evaluation of Upper Cretaceous strata. Limited number of samples did not provide foraminiferal content large enough to give relevant information for biostratigraphic conclusions. Samples from older sediments of Whisky Bay and Kotick Point formations (Albian – Turonian) were either not fossiliferous or contained scarce specimens of agglutinated foraminifers. Foraminiferal assemblages from younger sediments of Hidden Lake and Santa Marta formations (Coniacian – Campanian) contained species with both agglutinated and calcareous types of tests. Many of studied marine sediments were barren of foraminifers, probably due to late diagenetic secondary decalcification. Taxonomy of low-diversified assemblages was carried out and a biostratigraphical and palaeobiogeographical significance discussed.

Efficiency of Co-Expression of Transcription Factors Pdx1, Ngn3, NeuroD and Pax6 with Insulin: A Statistical Approach
Authors: Toit Don F. du , Longo-Mbenza Benjamin , Page Benedict J. , Tchokonte-Nana Venant
Published: August 2013

Aim: The objective of this study was to investigate the time related proﬁle and efﬁciency of co-expression of the homeodomain proteins Pdx1, NeuroD, Ngn3, Pax6 and caspase3 with insulin, and to establish the time periods post PDL optimum for islets transplantation.
Study Design/Methods: In this experimental study, immunoﬂuorescent staining procedure was performed on deparafﬁnized pancreatic duct ligated (PDL) tissues of 78 Sprague–Dawley rats. Quantiﬁcation of protein coexpression was made using a computerized morphometry. The efﬁciency of co-expression was arbitrary deﬁned by the value of mean ratio (score without unit) of insulin expression divided by each expression index of the other proteins, occurring within the time interval of 12–24 h post PDL. Statistical tool was used to analyze the efﬁciency of co-expression of proteins; analysis of variances (one way ANOVA) was used to compare the means of co-expression indexes across the time periods pre- and post PDL. P-values less than 0.05 were considered statistically signiﬁcant; no post hoc test was done.
Results: The curve of insulin expression showed a crossover with that of the co-expression at different time periods pre- and post PDL. The optimal or higher efﬁciency of co-expression was observed for insulin and Ngn3 co-expression, while a good or medium efﬁciency was noted for the co-expression of insulin with Pdx1, insulin with NeuroD and insulin with Pax6. Low or weak efﬁciency was observed for the co-expression of insulin with caspase3.
Conclusion: We therefore propose an early islets transplantation using 12–24 h post PDL harvested pancreatic tissues.
Therapy and prophylaxis in newborn patients
Authors: Manzoni Paolo
Published: August 2013

Fluconazole is the most used drug for antifungal prophylaxis in neonatal population. Despite its effectiveness, sometimes fungal infections occur also in newborn patients undergoing fluconazole prophylaxis: this is mainly due both to biofilm formation in patients who carry a central venous catheter (CVC), a common condi­tion among premature babies, and to the occurrence of an infection by a Candida subspecies with intrinsic resistance to fluconazole (e.g.: C. glabrata and C. krusei). A number of antifungal agents are approved for pediatric use, and their limits and advantages are analyzed in this article, but only micafungin is authorized for use in neonatal patients. Further trials are required in order to assess whether additional drugs could have a similar indication for neonatal use. A big issue is the correct identification of the most effective dosing regimen, because the drug pharmacokinetics is peculiar and somewhat unpredictable in newborn patients. In addition to fluconazole prophylaxis, other measures could be taken to prevent fungal infections in at-risk neonates, such as increasing hygienic measures, encouraging breast-feeding, removing CVCs, using probiotics, and decreasing or avoiding the use of drugs promoting the development of systemic mycoses.
Doble ronda electoral y apoyo al presidente. El caso de Perú
Authors: Salazar-Elena Rodrigo
Published: August 2013

The paper looks to establish the impact of runoff voting systems for electing presidents on the president’s legitimacy, studying the second presidency of Alan García in Peru. At first sight, this case seems to be at odds with the perspective that associates runoff voting with legitimacy. The analysis focuses on the evaluation made by citizens to whom the candidate Alan García was not the first preference, but nevertheless voted for him in the second round. Our findings suggest that judgments made by this group of citizens are not different from those made by those who had García as their first preference. If the two-round system didn’t matter, this group would behave like those who preferred Ollanta Humala to Alan García. Results are robust to inclusion of preferences over policies and cleavages as controls. They are consistent with theoretical expectations that come from asserting a sense of identification by citizens towards the candidate they vote for.
Mercosur, the Role of Ideas and a More Comprehensive Regionalism
Authors: Caballero Santos Sergio
Published: August 2013

Mercosur’s political agenda experienced a “redefinition” after the 1999-2002 regional crisis. The emergence of issues related to pre-existing asymmetries and the creation of a regional Parliament, amongst other things, show the importance of the new sociopolitical agenda since 2003. Thus, a broader and more comprehensive scope which includes an ideational approach is required. Nevertheless, according to presidential discourses, more steps forward should be expected in South American regional integration.

Fe3O4 Nanoparticles Embedded in Uniform Mesoporous Carbon Spheres for Superior High‐Rate Battery Applications
Authors: Chen Yu , Song Bohang , Li Meng , Lu Li , Xue Junmin
Published: August 2013

Robust composite structures consisting of Fe3O4 nanoparticles (∼5 nm) embedded in mesoporous carbon spheres with an average size of about 70 nm (IONP@mC) are synthesized by a facile two‐step method: uniform Fe3O4 nanoparticles are first synthesized followed by a post‐synthetic low‐temperature hydrothermal step to encapsulate them in mesoporous carbon spheres. Instead of graphene which has been extensively reported for use in high‐rate battery applications as a carbonaceous material combined with metal oxides mesoporous carbon is chosen to enhance the overall performances. The interconnecting pores facilitate the penetration of electrolyte leading to direct contact between electrochemically active Fe3O4 and lithium ion‐carrying electrolyte greatly facilitating lithium ion transportation. The interconnecting carbon framework provides continuous 3D electron transportation routes. The anodes fabricated from IONP@mC are cycled under high current densities ranging from 500 to 10 000 mA g−1. A high reversible capacity of 271 mAh g−1 is reached at 10 000 mAh g−1 demonstrating its superior high rate performance.
Production of H2 by Ethanol Photoreforming on Au/TiO2
Authors: Puga Alberto V. , Forneli Amparo , García Hermenegildo , Corma Avelino
Published: August 2013

A deposition‐precipitation method is used to prepare Au/TiO2 solids (0.45–1.7 wt% Au). These materials, consisting of gold nanoparticles (diameter range = 1.5–6.5 nm) supported on the surface of TiO2, are used as photocatalysts for the ethanol photoreforming reaction under either UV‐rich or simulated solar light. The main products of such reactions are H2 in the gas phase and acetaldehyde in the liquid phase according to the reaction CH3CH2OH → CH3CHO ‐ H2. Among the gaseous products, H2 amounts to around or above 99% in all cases; other minor products found in the gas phase are, in decreasing order of molar production: CH4 > CO > C2H4 > CO2 > C2H6 > C3H8. The photoactivity is lower under CO2 atmosphere, as compared to analogous reactions performed under Ar. The H2 production yields are very high (up to a maximum 30 mmol gcat−1 h−1) under UV irradiation, and increase with increasing gold loading. The reactions under simulated solar light also yield significant amounts of H2 (5–6 mmol gcat−1 h−1) as the main gaseous product.
Relation of Nanostructure and Recombination Dynamics in a Low‐Temperature Solution‐Processed CuInS2 Nanocrystalline Solar Cell

Published: August 2013

The understanding and control of nanostructures with regard to transport and recombination mechanisms is of key importance in the optimization of the power conversion efficiency (PCE) of solar cells based on inorganic nanocrystals. Here, the transport properties of solution‐processed solar cells are investigated using photo‐CELIV (photogenerated charge carrier extraction by linearly increasing voltage) and transient photovoltage techniques; the solar cells are prepared by an in‐situ formation of CuInS2 nanocrystals (CIS NCs) at the low temperature of 270 °C. Structural and morphological analyses reveal the presence of a metastable CuIn5S8 phase and a disordered morphology in the CuInS2 nanocrytalline films consisting of polycrystalline grains at the nanoscale range. Consistent with the disordered morphology of the CIS NC thin films, the CIS NC devices are characterized by a low carrier mobility. The carrier density dynamic indicates that the recombination kinetics in these devices follows the dispersive bimolecular recombination model and does not fully behave in a diffusion‐controlled manner, as expected by Langevin‐type recombination. The mobility–lifetime product of the charge carriers properly explains the performance of the thin (200 nm) CIS NC solar cell with a high fill‐factor of 64% and a PCE of over 3.5%.
Different associations of subscapular and triceps skinfold thicknesses with pathogen load: An ecogeographical analysis
Authors: Wells Jonathan C.K. , Cortina‐Borja Mario
Published: August 2013

Objectives

The dominant evolutionary perspective on adipose tissue has considered it a relatively inert energy store. However, variability in adipose tissue distribution has recently been associated with age, parity, thermal environment and immune function. Genes regulating the innate immune system are more strongly expressed in deep‐lying than peripheral adipose tissue. We hypothesized that central adiposity would correlate more strongly than peripheral adiposity with pathogen load across populations.

Methods

Primary outcomes were subscapular and triceps skinfolds from 133 male and 106 female populations. National values for disability‐adjusted life years lost, attributable to infectious diseases, were used to index pathogen load. Linear mixed‐effects models were fitted, including a random effect term by country to investigate the association of each skinfold with pathogen load, adjusting for the other skinfold, mean annual temperature and clustering of the populations across countries.

Results

Adjusting for subscapular skinfold, triceps skinfold was not associated with pathogen load in either sex. Adjusting for triceps skinfold, subscapular skinfold was negatively associated with pathogen load in both sexes (P < 0.02). These associations were independent of variability in annual temperature. Adjusting for pathogen load and temperature, Oceanic populations had a different fat distribution compared to other populations.

Conclusions

Across populations, higher pathogen load was associated with reduced central but not peripheral skinfolds, supporting the hypothesis that central adiposity is more closely associated with immune function. This scenario might explain why some populations increase disproportionately in central adiposity when the environment shifts from low‐energy high‐pathogen status to high‐energy low‐pathogen status.

Objectives

This study assesses the relationships between social context (family and inter‐peer context), stress, and illness in 5–6‐year‐old children.

Methods

To this end, data were collected on spontaneous social interpeer behavior; families provided data on stress, anxiety, and parental acceptance‐rejection; and the children's pediatricians provided data relative to their health. Data on stress‐related hormones (cortisol) were collected using saliva samples.

Results

The results revealed that none of the variables examined were significantly related to illness development in the subjects in the sample group. Cortisol levels, however, were positively associated with a record of chronic or congenital illnesses, the manifestation of behaviors related to the search for leadership status in the group and the presence of stressful events in the family environment.

Conclusions

Despite finding no relationship between children's level of adrenocortical activity and the contracting or contingent development of diseases, we did find that chronic/congenital diseases may constitute a source of early stress in childhood. Certain conditions of uncertainty in the social context (family and interpeer) also seem to constitute different sources of stress. Am. J. Hum. Biol., 25:606‐616, 2013. © 2013 Wiley Periodicals, Inc.

Information on the distribution and abundance of sympatric great apes (Pan troglodytes troglodytesandGorilla gorilla gorilla) are important for effective conservation and management. Although much research has been done to improve the precision of nest‐surveys, trade‐offs between data‐reliability and research‐efficiency have not been solved. In this study, we used different approaches to assess the landscape‐scale distribution patterns of great apes. We conducted a conventional nest survey and a camera‐trap survey concurrently, and checked the consistency of the estimates. We divided the study area (ca. 500 km2), containing various types of vegetation and topography, into thirty 16‐km2grids (4 km × 4 km) and performed both methods along 2‐km transects centered in each grid. We determined the nest creator species according to the definitions by Tutin & Fernandez [Tutin & Fernandez, 1984, Am J Primatol 6:313–336] and estimated nest‐site densities of each species by using the conventional distance‐sampling approach. We calculated the mean capture rate of 3 camera traps left for 3 months at each grid as the abundance index. Our analyses showed that both methods provided roughly consistent results for the distribution patterns of the species; chimpanzee groups (parties) were more abundant in the montane forest, and gorilla groups were relatively homogeneously distributed across vegetation types. The line‐transect survey also showed that the number of nests per nest site did not vary among vegetation types for either species. These spatial patterns seemed to reflect the ecological and sociological features of each species. Although the consistent results may be largely dependent on site‐specific conditions (e.g., high density of each species, distinct distribution pattern between the two species), conventional nest‐surveys and a subsequent check of their consistency with independent estimates may be a reasonable approach to obtain certain information on the species distribution patterns. Further analytical improvement is necessary for camera‐traps to be considered a stand‐alone method. Am. J. Primatol. 75:1220–1230, 2013. © 2013 Wiley Periodicals, Inc.
Male philopatry in spider monkeys revisited
Authors: Aureli Filippo , Di Fiore Anthony , Murillo‐Chacon Evin , Kawamura Shoji , Schaffner Colleen M.
Published: August 2013

Dispersal patterns are critical for understanding social systems as they influence social interactions and relationships. Spider monkeys (Atelesspp.) are typically described as being characterized by male philopatry and female dispersal, with these patterns reflected in stronger affiliative and cooperative relationships among males than among females. Recent findings, however, indicate that male–male relationships may not be as uniformly strong as previously thought, which suggests that male philopatry in spider monkeys may not be universal. Here, we report the first confirmed cases of male immigration and group takeover in spider monkeys. Data were collected on one community ofAteles geoffroyiin northwestern Costa Rica. Behavioral and demographic data were recorded during subgroup follows across 6.5 years, and fecal samples of community members were collected for genetic analysis of relatedness. We documented two separate cases of immigration involving multiple males, which resulted in take‐over of the study community by extra‐community males and the concomitant disappearance of the resident males. In the study community, males were no more closely related to one another, on average, than females were, contrary to what would be expected if males were the more philopatric sex. Comparison of corrected assignment indices for males and females also revealed no evidence of sex‐biased dispersal. Our findings suggest that in spider monkeys male immigration may occur under certain demographic circumstances, contributing to a view of greater flexibility in their social system than previously appreciated. This discovery has implications for other species that are typically characterized by male philopatry. Am J Phys Anthropol 152:86–95, 2013. © 2013 Wiley Periodicals, Inc.

Published: August 2013

The synthesis of oligocarbonate diols from propylene carbonate (PC) and α,ω‐diols with hydrocarbon chain of various length is presented and discussed. Syntheses with different catalysts and molar ratio of the reactants were performed. Novel method of the synthesis of oligo(ester–carbonate) diols based on PC, dimethyl succinate, adipate or terephthalate, and α,ω‐diols was investigated. The resultant oligomerols did not contain any oxy‐1,2‐propylene fragments as well as other ether units in their chemical structure. Based on the obtained oligocarbonate and oligo(ester–carbonate) diols, polyurethanes were obtained according to the prepolymer method using isophorone and hexamethylene diisocyanate and water as a chain extender. The obtained products exhibited very good mechanical properties—tensile strength up to 50 MPa with 425% elongation at break [for PUR based on oligo(tetramethylene carbonate) diol] and 45 MPa, 625% [for (oligo(tetramethylene succinate‐co‐carbonate)diol with 44 mol % of carbonate units]. © 2013 Wiley Periodicals, Inc.

Method comparison on estimation for an unknown specimen in a heteroscedastic controlled calibration model
Authors: Tsai Jia‐Ren , Liao Chen‐Tuo
Published: August 2013

In analytical chemistry applications, statistical calibration models are commonly used to estimate the true value of an unknown specimen. In this article, we consider a heteroscedastic controlled calibration model in which both dependent and independent variables are subject to heteroscedastic measurement errors. The main task of using this model is to estimate the true value of an unknown regressor (independent variable) under the condition that a set of observations on its corresponding response (dependent variable) is available. We introduce four estimation methods to the problem of interest, including generalized least squares (GLS), modified least squares, corrected score, and expectation maximization‐based (EM‐based) methods. Furthermore, an interval estimation based on an asymptotic method is also derived. We compare their performance through detailed simulation studies. In consequence, GLS and EM‐based methods are recommended in practical use. A real data example is given to illustrate the application of the calibration model.
