Socially engaged art and the affects of Chinese rural community: A case study of ‘Someone Nearby’
Authors: Zhou Yanhua
Published: November 2018

This article examines Yangdeng Cooperatives, a socially engaged art project in the rural area of Guizhou Province, Southwest of China (2012–present) with a special focus on an artwork named ‘Someone Nearby’ (2016). The work is created by a young artist Zhang Chao, also a member of Yangdeng Cooperatives. Zhang uses his Wechat, a digital chatting App popular in mainland China, to set up a dialogical system between the artist and the local residents in Yangdeng Township in order to explore local residents’ daily life in detail. By using contemporary affect theory, with a special focus on Lauren Berlant’s (2011) discussions of ‘cruel optimism’, I investigate how a socially engaged art project in the rural area of China reveals local residents’ daily life dilemma. Moreover, I attempt to explore how this dilemma is operated by the affective apparatus of Yangdeng society, which is driven by the cruel optimism related to people’s attachments to their good-life fantasy under the precarious condition of China’s urbanization. I argue that ‘cruel optimism’ is the everyday affects of the local residents which is used to deal with the ordinary crisis that they are encountering every day, and Zhang Chao’s work examines the ‘cruel optimism’, the product of the affective apparatus of Yangdeng society, through its social engagements.

Groundwater Level Fluctuation in Response to Climatic Variation and its Geotechnical Implication in Part of Awgu Shale, Central Benue Trough, Nigeria
Authors: . Umar , Degree Nuhu , . Idris , Giza Ibrahim , Aliyu Itari Abdullahi
Published: November 2018

The role of climate variation on groundwater level and its geotechnical implication was studied. Static water levels (SWL) and elevations of 57 dug wells and boreholes were measured during dry and wet seasons. The differences between the SWL for dry and wet season was used to establish the depth of groundwater fluctuation, while geophysical investigation was conducted to delineate the subsurface geo-electric layers. This information is vital for groundwater assessment and evaluation, however, this research is biased towards its geotechnical implications. SWL varied between 5.5 – 13 and 2.2 - 9.2 meters below sea level (mbsl), while groundwater elevation ranges from 131.8 – 157.2 and 136-160 meters above sea level (masl) for dry and wet seasons respectively. The depth of fluctuation (active zone) lies between 1.1 – 5.9 mbsl. The wells showed a direct rapid response to short term seasonal precipitation attributable to climate variation, which implies a shallow aquifer. Groundwater flows from the northern parts towards the southern parts. Foundations in the study area are underlain by sandy-clays, clays and sands as revealed by geophysical investigations. Engineering structures with shallow foundation may be prone to shrink-swell behavior, and should be laid beyond active zone.
Principal component analysis of rare earth elements in Sechahun iron deposit, central Iran.
Authors: Sarparandeh Mohammadali , Hezarkhani Ardeshir
Published: November 2018

Principal component analysis (PCA) is a sufficient way for finding the groups of correlated features. In geochemical exploration of precious metals, it helps to cluster the elements. Especially for rare earth elements (REEs), because of multiplicity of parameters, the proposed method helps to have a better interpretation. Geochemical exploration programs aim to find the hidden information about specific element(s), its abundance, its behavior and its relation with minerals and some other elements. REEs are a group of elements with same chemical behavior. However, some chemical characteristics of light rare earth elements (LREEs) and heavy rare earth elements (HREEs) are different. In this study, relationship between these elements was investigated by applying PC analysis method in Kiruna-type iron ore deposit of Se-Chahun in Central Iran. The four first PCs covered the most variances of the REEs. All the elements showed a correlation together with exception of La, Ce, Nd, Yb and Y. Results of PC analysis are related to the anomaly of Rare earth elements. It can be concluded that in anomalous areas, loadings of the principal components are affected by variance and anomalous content of the elements.

A study was conducted in the Department of Agronomy, Bangladesh Agricultural University (BAU), Mymensingh from April to August 2012 to examine the salinity tolerance of eight jute varieties (CVE-3, C-83, CVL-1, BJC-7370, O-795, O-9897, OM-1, O-72) and two kenaf varieties (HC-95 and HC-2). Initially germination of these varieties were evaluated under six salinity levels viz. 0mM, 20mM, 40mM, 60mM, 80mM, and 100mM NaCl in the seed laboratory of the Department of Agronomy. Afterwards, all the varieties was grown in pots in the net house under four salinity levels viz. 0mM, 25mM, 50mM, and 75mM. The results from the germination study revealed that under control condition (0mM NaCl) all the jute varieties showed germination more than 80% both at 7 and at 14 days after seed sowing, whereas kenaf varieties had germination a little less than 80%. Among the jute varieties, O-72 showed the highest germination (92%), which was statistically similar with those of OM-1(91%), O-795 (90%), and C-83(87%). Salinity stress decreased germination drastically in all of the jute and kenaf varieties. A salinity level of 100mM caused the highest germination inhibition (74.70%) in jute variety CVL-1, which was very close to those of BJC-7370 and O-72. On the other hand, the lowest germination inhibition (51.11%) was recorded in jute variety O-795. The results of the pot trail showed that the plant characters of jute and kenaf varieties were affected significantly by salinity stress. All the varieties produced their respective plant height, number of leaves per plant, and plant dry weight under control condition (no salinity). Among these varieties, CVE-3 produced the highest plant height (145.2cm), and total dry weight (22.55g), whereas O-72 produced the highest number of leaves per plant (24.67). All these plant characters decreased sharply due to salinity stress irrespective of variety. However, the rate of decrease of plant characters occurred differentially in the jute and kenaf varieties. The highest rate of decrease in number of leaves (74.22%) was found from the variety CVE-3, whereas the lowest one was recorded from the variety HC-2 (51.68%). Salinity stress caused the highest decrease in total plant dry weight (73.68%) in the variety CVL-1 and plant height (73.64%) also in the variety CVL-1. On the contrary, the lowest decrease in plant dry weight (50.99%) was found in the variety O-9897 and plant height also in variety O-9897 (50.88%). Based on the results from germination test and pot trail, it can be inferred that jute variety O-9897 appeared to be the most salt tolerant followed by O-795, HC-2, HC-95, CVE-3, O-72, C-83, BJC-7370, OM-1, and CVL-1.

Published: November 2018

Neste trabalho foram realizados testes de controle de qualidade em dispositivos de exibição de imagens (monitores) empregados em radiodiagnóstico médico e em monitores comuns. A avaliação foi realizada com base na curva característica da luminância em função da menor diferença detectável, curva DICOM GSDF. Nos testes foi empregado um fotodetector conectado a um eletrômetro como um método alternativo de medidor de luminância, a partir de grandezas elétricas. Com o auxílio de um LED no lugar do fotodetector, definindo-se o valor de ângulo sólido do fotodetector, foi possível a conversão de unidades de medida de iluminância em luminância, para a classificação dos monitores como primários ou secundários. Os seguintes testes foram realizados: reflexão difusa, reflexão especular, reflexão interna ou velamento, resolução, ruído, resposta de luminância e contraste e uniformidade de luminância. Para os testes, empregou-se imagens padrão teste denominadas de TG18 disponibilizadas pela Associação Americana dos Físicos em Medicina (AAPM). As recomendações de controle de qualidade para análise dos resultados foram baseadas no protocolo da própria AAPM e outros da Europa. Os softwares utilizados foram o Radiant DICOM e o Isyte Radiology da Phillips. O dispositivo alternativo possibilitou a classificação dos monitores, mostrando-se útil para a medição de luminância na ausência de fotômetro, que é o equipamento idealmente empregado para esse tipo de avaliação.

Este estudo buscou verificar as principais manifestações clínicas apresentadas por pacientes portadores de doença hepática gordurosa não alcoólica (DHGNA) com diferentes graus de acúmulo esteatogênico acompanhados em dois centros ambulatoriais de Recife-PE. Estudo transversal, multicêntrico, de natureza quantitativa, realizado com indivíduos adultos diagnosticados com DHGNA via ultrassonografia. As variáveis coletadas foram: idade, gênero, grau de DHGNA, dados bioquímicos (TGO, TGP, GGT, FA, colesterol total, HDL, LDL, triglicerídeos Glicemia em jejum,), pressão arterial e dados antropométricos (peso, altura, circunferência da cintura e índice de massa corporal). Foram revisados os prontuários e elencados as manifestações clinicas apresentadas. Para definir síndrome metabólica utilizou-se os critérios do NCEP-ATPIII e para definir obesidade os critérios da OMS e OPAS. As variáveis foram analisadas como frequências e associações por teste de inferência estatística. Foram selecionados 110 indivíduos, em sua maioria do sexo feminino (80,9%) e com menos de 60 anos. O grau de esteatose moderado foi prevalente na amostra. Das manifestações encontradas, a hipertensão arterial (80%), obesidade (73,6%) e síndrome metabólica (67,3%) foram as mais importantes. As médias de glicemia em jejum se associaram aos graus de esteatose (p=0.023), assim como o colesterol total (p=0.038). Inúmeras manifestações clinicas acham-se no escopo da DHGNA. Nesse estudo, a hipertensão arterial e obesidade foram as mais importantes. Ademais, um descontrole glicêmico tanto quanto maior aumenta com a gravidade da doença e, portanto, piora o prognóstico. Logo, evidencia-se a necessidade ações multidisciplinares promotoras de saúde ligadas a mudanças no estilo de vida.
A telescope for LISA – the Laser Interferometer Space Antenna
Authors: Escudero Sanz Isabel , Heske Astrid , Livas Jeffrey C.
Published: November 2018

Gravitational waves are a prediction of Einstein’s general relativity theory. In autumn 2017, the Laser Interferometer Gravitational-Wave Observatory (LIGO; https://www.ligo.caltech.edu/) experiment reported the first detection of gravitational waves in addition to electromagnetic radiation from the collision of two neutron stars. This marks the first time that a cosmic event has been viewed in both gravitational waves and light and opens the door to a new type of astronomical observatory based on gravitational waves. The gravitational wave spectrum covers a broad span of frequencies and requires both space- and ground-based observatories to cover the full range. Space-based gravitational wave observatories, such as the proposed Laser Interferometer Space Antenna (LISA), operate at frequencies between 0.1 mHz and 1 Hz and complement the frequency range of 30–1000 Hz accessible by ground-based gravitational wave observatories, such as LIGO. A rich array of high-energy astrophysical sources is expected in the LISA measurement band. LISA was selected in 2017 as the third large mission of the Cosmic Vision program of the European Space Agency. The National Aeronautics and Space Administration will collaborate on both the scientific and technical aspects of this mission. This paper addresses the design of the optical telescope as an essential component of LISA’s long-distance interferometric measurement system.
Core-Periphery Relations in the Eurozone
Authors: De Grauwe Paul , Ji Yuemei
Published: November 2018

We argue that the case for the existence of some deterministic force that condemns countries in the periphery to stay in the periphery indefinitely, is weak. Countries that are in the periphery today can become part of the core and vice versa. We also argue that the long run success of the Eurozone depends on a continuing process of political unification. Political unification is needed because the Eurozone has dramatically weakened the power and legitimacy of nation states without creating a nation at the European level. This is particularly true in the field of stabilization. The political willingness to go in this direction, however, is non-existent today. There is no willingness to provide a common insurance mechanism that would put taxpayers in one country at risk of having to transfer money to other countries. Under those conditions the sovereign bond markets in the Eurozone will continue to be prone to instability.
Binding as agree and index raising: The case of Polish accusative object experiencers
Authors: Witkoś Jacek , Dziubała-Szrejbrowska Dominika , Łęska Paulina
Published: November 2018

This paper aims to account for peculiar binding properties of non-nominative arguments of Polish psychological predicates focusing on accusative Object Experiencers (hence, OE). It has been observed that although Polish anaphors are subject oriented, they can be bound by accusative experiencers (Bondaruk and Szymanek 2007; Tajsner 2008; Wiland 2016). At the same time, these arguments, unlike nominative subjects, are also proper antecedents for both reflexive and pronominal possessives. This mixed behaviour poses a puzzle for the traditional formulation of Binding Theory (Chomsky 1981, 1986; Manzini and Wexler 1987; Rappaport 1986; Willim 1986/1989; Reinders-Machowska 1991), which assumes complementarity between anaphors and pronominals in their local domains and plainly states that the subject is the privileged binder in Slavic. We base our analysis on a number of recent proposals, including Hicks (2009), Safir (2014) and Nikolaeva (2014), following Hestvik (1992). The proposal implements the concept of binding as (upward) Agree as well as Index Raising (IR), where the head of the anaphoric/pronominal element (henceforth the index) is (covertly) moved and adjoined to v or T. Lexicalisation and distribution of anaphoric and pronominal elements is determined by two factors: the movement of the index and the case position of the binder.
A note on lexicalizing ‘what’ and ‘who’ in Russian and in Polish
Authors: Wiland Bartosz
Published: November 2018

The contrast between the Russiančtoand the Polishco‘what’ is syntactic and reflects the way in which an identical sequence of features in the syntactic representation becomes realized as morphology. Specifically, I argue that this scenario follows from a spell-out mechanism outlined in Starke (2018), where prefix formation, as in the Russian tri-morphemicčt-obut not in the Polish bi-morphemicc-o, takes place in order to spell out a feature which cannot be spelled out in the mainline derivation. Next, I explore a possibility that the wh-prefix inkto‘who’, the same form in Russian and Polish, merges with a syntactically different stem than the one present in the lexical items for ‘what’, a scenario more transparently visible on the example of Englishwh-atandwh-o.
Cardinal numerals and complex numerals as specifiers
Authors: Witkoś Jacek , Dziubała-Szrejbrowska Dominika
Published: November 2018

The goal of this study is to argue for a more widespread application of a uniform representation of Numeral Noun Constructions (NNCs) which captures both patterns with higher numerals (≥5, NumH) agreeing in case with the modified noun (case matching pattern) or bearing a distinct case from a noun (case independence pattern) in Polish and in other languages. Our account draws on the analysis of cardinal numerals in Bailyn (2004) in which both agreeing and non-agreeing numerals are placed within the projection (QP) of the functional head FQ, but contrary to Bailyn (2004), it advocates a predominant cardinal-as-specifier representation of NNCc and complex NNCs in Polish, a language whose numeral/quantificational system is fairly challenging. We propose that many cases discussed in Bošković (2006), Ionin and Matushansky (2006), Kayne (2010), Danon (2012), Norris (2014) and Willim (2015) may have a uniform representation. In short, both the case matching and the case independence patterns are represented as equivalent to the cardinal-as-specifier representation. This serves to preserve derivational and structure building transparency and avoids the issue of look-ahead and the No Tampering ban (Chomsky 2000, 2001; Stepanov 2001, 2007). In the spirit of Burzio’s (1986) Generalization we submit that the case valuation capacity of FQ is conditioned directly by an independent case (feature) of NumP occupying FQ’s specifier position. Our proposal receives further support from recent work on the structure of complex numerals in Di Sciullo (2015, 2017) and Kayne (2016), where their component parts are combined in asymmetric structures involving silent functional projections.
Effects of Calcium Carbonate Nanoparticles and Fly Ash on Mechanical and Permeability Properties of Concrete
Authors: Nejad Fereidoon Moghadas , Tolouei Morteza , Nazari Hossein , Naderan Ali
Published: November 2018

The use of additives to supplement or replace cement in concrete is a well-studied topic. The use of fibers, polymers, minerals, and even nanomaterials has been considered for improving concrete properties such as permeability and strength, and these issues are constantly under investigation. In this study, the mechanical properties and permeability of concrete containing calcium carbonate (CaCO3) nanoparticles and fly ash are investigated. For this purpose, concrete specimens with different proportions of nanoparticles and fly ash were prepared and aged for 7 days and 28 days to investigate the mechanical properties via compressive strength tests, tensile strength tests, and flexural strength tests under three-point loading and also to study the permeability properties via full water absorption tests and the testing of penetration depth under water pressure. To determine the distribution of nanoparticles and their size and microstructure, scanning electron microscopy (SEM) images were obtained, and energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD) analyses were performed. The results show the positive effect of CaCO3 nanoparticles in filling concrete pores, which leads to increased strength and reduced permeability. In general, the SEM images and EDS and XRD analyses showed that there was a good correlation between the materials used in the concrete and also that the nanoparticles were appropriately distributed in the concrete samples.
Response of Concrete to Incremental Aggression of Sulfuric Acid
Authors: Mahmoud M. H. , Bassuoni M. T.
Published: November 2018

There is lack of standardized tests for specifically evaluating the resistance of concrete to sulfuric acid attack, which has caused great variability, for example, in terms of solution concentration, pH level/control, etc., among previous studies in this area. Accordingly, there are conflicting data about the role of key constituents of concrete (e.g., supplementary cementitious materials [SCMs]) and uncertainty about building codes’ stipulations for concrete exposed to sulfuric acid. Hence, the aim of this study was to assess the behavior of the same concretes, prepared with single and blended binders, to incremental levels (mild, severe, and very severe) of sulfuric acid solutions over 36 weeks. The test variables included the type of cement (general use [GU] or portland limestone cement [PLC]) and SCMs (fly ash, silica fume, and nanosilica). The severe (1 %, pH of 1) and very severe aggression (2.5 %, pH of 0.5) phases caused mass loss of all specimens, with the latter phase providing clear distinction among the performance of concrete mixtures. The results showed that the penetrability of concrete was not a controlling factor under severe and very severe damage by sulfuric acid attack, whereas the chemical vulnerability of the binder was the dominant factor. Mixtures prepared from the PLC performed better than those prepared from GU. While the quaternary mixtures that consisted of GU or PLC, fly ash, silica fume, and nanosilica showed the highest mass losses after 36 weeks, the binary mixtures incorporating GU or PLC with fly ash had the lowest mass losses.
Buckling and Free Vibration Behavior of Cenosphere/Epoxy Syntactic Foams under Axial Compressive Loading
Authors: Waddar Sunil , Pitchaimani Jeyaraj , Doddamani Mrityunjay , Gupta Nikhil
Published: November 2018

The buckling and free vibration behavior of cenosphere/epoxy syntactic foams under axial compressive loading are investigated experimentally in this work. The buckling load is obtained from the load-deflection curve based on the Double Tangent Method (DTM) and Modified Budiansky Criteria (MBC). Furthermore, the influence of an axial compression load on the natural frequencies associated with the first three transverse bending modes is analyzed. Finally, the buckling loads predicted using DTM and MBC are compared to the buckling load calculated based on the vibration correlation technique. It is observed that the buckling loads predicted through the three different methods are in close agreement. The experimental results revealed that the buckling load and natural frequency of the syntactic foams increase with the cenosphere volume fraction. It is observed that the natural frequencies reduce with increases in the axial compression load for all the modes. However, a rapid increase in the fundamental frequency is observed when the compressive load is near and beyond the critical buckling load.
Caroline Chisholm: public pedagogy personified

Authors: Fernandes Henrique Campagnollo Dávila , Zanello Valeska
Published: November 2018

Objetivo: problematizar a noção biomédica patológica sobre as alucinações auditivas, através de uma contextualização histórica e cultural. Método: revisão integrativa de literatura, com busca nas bases de dados Publicações Médicas (PubMed) e Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). Os dados foram divididos em cinco subtópicos, referentes aos períodos históricos, a uma nova abordagem do fenômeno no campo da saúde e da cultura. Resultados: na Antiguidade, as alucinações eram um meio de comunicação com as divindades e na Idade Média foram relacionadas à espiritualidade. Culturas que não sofreram influência da medicina ocidental possuem outros vieses sobre o fenômeno. Conclusões: outras formas de compreender as alucinações devem ser consideradas, a fim de evitar a medicalização e o aumento do sofrimento, e proporcionar a criação de possibilidades de existência e convivência do próprio sujeito com sua experiência.

Published: November 2018

Objetivo: caracterizar os ouvidores de vozes que participaram de um Congresso no Brasil, bem como o processo relacional com as vozes durante as suas vidas. Métodos: estudo qualitativo de abordagem descritiva, com 12 ouvidores de vozes. Os dados foram coletados em outubro de 2017. As entrevistas foram registradas na forma de anotações, organizadas e analisadas a partir de temáticas. Resultados: os participantes são em sua maioria homens, acima de 40 anos. O surgimento das vozes ocorreu devido a eventos traumáticos, antes dos 20 anos. O uso de medicamentos é a estratégia mais utilizada para o enfrentamento das vozes, enquanto escrever sobre as vozes é pouco utilizada. A maioria dos ouvidores acreditam que as vozes possam ser de entidades, bons espíritos, deuses, fantasmas e anjos. Considerações Finais: este estudo apresentou informações que potencializam a difusão do Movimento dos Ouvidores de Vozes, estimulando novas produções em diferentes cenários.

Balancing Prediction and Sensory Input in Speech Comprehension: The Spatiotemporal Dynamics of Word Recognition in Context
Authors: Klimovich-Gray Anastasia , Tyler Lorraine K. , Randall Billi , Kocagoncu Ece , Devereux Barry , Marslen-Wilson William D.
Published: November 2018

Spoken word recognition in context is remarkably fast and accurate, with recognition times of ∼200 ms, typically well before the end of the word. The neurocomputational mechanisms underlying these contextual effects are still poorly understood. This study combines source-localized electroencephalographic and magnetoencephalographic (EMEG) measures of real-time brain activity with multivariate representational similarity analysis to determine directly the timing and computational content of the processes evoked as spoken words are heard in context, and to evaluate the respective roles of bottom-up and predictive processing mechanisms in the integration of sensory and contextual constraints. Male and female human participants heard simple (modifier-noun) English phrases that varied in the degree of semantic constraint that the modifier (W1) exerted on the noun (W2), as in pairs, such as “yellow banana.” We used gating tasks to generate estimates of the probabilistic predictions generated by these constraints as well as measures of their interaction with the bottom-up perceptual input for W2. Representation similarity analysis models of these measures were tested against electroencephalographic and magnetoencephalographic brain data across a bilateral fronto-temporo-parietal language network. Consistent with probabilistic predictive processing accounts, we found early activation of semantic constraints in frontal cortex (LBA45) as W1 was heard. The effects of these constraints (at 100 ms after W2 onset in left middle temporal gyrus and at 140 ms in left Heschl's gyrus) were only detectable, however, after the initial phonemes of W2 had been heard. Within an overall predictive processing framework, bottom-up sensory inputs are still required to achieve early and robust spoken word recognition in context.

SIGNIFICANCE STATEMENTHuman listeners recognize spoken words in natural speech contexts with remarkable speed and accuracy, often identifying a word well before all of it has been heard. In this study, we investigate the brain systems that support this important capacity, using neuroimaging techniques that can track real-time brain activity during speech comprehension. This makes it possible to locate the brain areas that generate predictions about upcoming words and to show how these expectations are integrated with the evidence provided by the speech being heard. We use the timing and localization of these effects to provide the most specific account to date of how the brain achieves an optimal balance between prediction and sensory input in the interpretation of spoken language.
A Tale of Two Cities: Differences in Wine Culture in Nice and London
Authors: Gibson Lacey
Published: November 2018

The French Paradox is the theory that France has an unexpectedly low prevalence of coronary heart disease compared to levels that would be predicted by their high consumption of fats. Aside from high-fat foods, wine is portrayed by English media to be a staple of the French diet. In this article, I explore the wine-drinking cultures in Nice, France, and London, England, that were revealed by conducting semi-structured interviews, participant observation, and descriptive surveys. I describe two mealtime vignettes of my ethnographic experience that are symbolic of my main findings from this study. Specifically, I find that residents of Nice consume wine in smaller portions, often during shared social experiences at meals, whereas Londoners are more likely to consume wine in larger portions and more frequently for relaxation than their counterparts in Nice. Wine connoisseurship in London is a relatively novel practice, and wine drinking is often associated with the potential for inebriation, whereas mindful appreciation of high-quality wines is a staple element of French identity in Nice. Further epidemiological research is needed to determine causality of French wine culture's impact on cardiovascular health. However, it is evident from my research that the aesthetics of French wine culture may be a powerful tool to promote mindfulness and moderation.
MANAGEMENT OF ENDOCRINE DISEASE: The role of confirmatory tests in the diagnosis of primary aldosteronism
Authors: Morera Julia , Reznik Yves
Published: November 2018

The strategy for diagnosis of primary aldosteronism (PA) in the hypertensive population includes firstly a screening step, based on the measurement of plasma aldosterone-to-renin ratio (ARR), a test which must have high sensitivity, and secondly a confirmatory step based on the demonstration of excessive aldosterone production independent of the renin-angiotensin-aldosterone system (RAAS) activity. The high proportion of false-positive ARR results and conversely of actual PA without a persistent elevation in baseline plasma aldosterone concentration necessitates the addition of a confirmatory step in the work-up of PA diagnosis. The present review focuses on the description of the different dynamic tests available for demonstrating autonomy of aldosterone secretion, on the performance and limitations of confirmatory tests and on possible strategies for PA diagnosis which may either include or avoid the confirmatory step for PA diagnosis. Large prospective studies comparing different strategies with and without dynamic testing are mandatory to delineate clearly the role and limits of confirmatory tests in the work-up of PA.

Published: November 2018

In this paper, we consider a cholera model with periodic incidence rate and saturated treatment function. Under certain conditions, we establish a criterion on the global exponential stability of positive periodic solutions for this model by using a novel method. We illustrate our theoretical results with numerical simulations by using Matlab.
Fixed-time control of delayed neural networks with impulsive perturbations
Authors: Hu Jingting , Sui Guixia , Lu Xiaoxiao , Li Xiaodi
Published: November 2018

This paper is concerned with the fixed-time stability of delayed neural networks with impulsive perturbations. By means of inequality analysis technique and Lyapunov function method, some novel fixed-time stability criteria for the addressed neural networks are derived in terms of linear matrix inequalities (LMIs). The settling time can be estimated without depending on any initial conditions but only on the designed controllers. In addition, two different controllers are designed for the impulsive delayed neural networks. Moreover, each controller involves three parts, in which each part has different role in the stabilization of the addressed neural networks. Finally, two numerical examples are provided to illustrate the effectiveness of the theoretical analysis.

OBJECTIVES:

To compare the neonatal outcomes of very preterm triplets with those of matched singletons using a large international cohort.

METHODS:

A retrospective matched-cohort study of preterm triplets and singletons born between 2007 and 2013 in the International Network for Evaluation of Outcomes in neonates database countries and matched by gestational age, sex, and country of birth was conducted. The primary outcome was a composite of mortality or severe neonatal morbidity (severe neurologic injury, treated retinopathy of prematurity, and bronchopulmonary dysplasia). Unadjusted and adjusted odds ratios with 95% confidence intervals (CIs) were calculated for model 1 (maternal hypertension and birth weight z score) and model 2 (variables in model 1, antenatal steroids, and mode of birth). Models were fitted with generalizing estimating equations and random effects modeling to account for clustering.

RESULTS:

A total of 6079 triplets of 24 to 32 weeks’ gestation or 500 to 1499 g birth weight and 18 232 matched singletons were included. There was no difference in the primary outcome between triplets and singletons (23.4% vs 24.0%, adjusted odds ratio: 0.91, 95% CI: 0.83–1.01 for model 1 and 1.00, 95% CI: 0.90–1.11 for model 2). Rates of severe neonatal morbidities did not differ significantly between triplets and singletons. The results were also similar for a subsample of the cohort (1648 triplets and 4944 matched singletons) born at 24 to 28 weeks’ gestation.

CONCLUSIONS:

No significant differences were identified in mortality or major neonatal morbidities between triplets who were very low birth weight or very preterm and matched singletons.
