An improved adaptive channel hopping scheme for WIA-PA Industrial Wireless Networks

Wireless Industrial communication technology becomes increasingly important and has attracted widespread attention for industrial applications. WIA-PA (Wireless Networks for Industrial Automation-Process Automation) standard is one of the three international industrial wireless standards. Because of operating on shared ISM band, anti-interference is a key issue and WIA-PA standard adopts adaptive channel hopping mechanism to coexist with other interfering systems. However, current WIA-PA standard does not present any specified scheme for the mechanism. In this paper, we propose an improved and integrated adaptive channel hopping scheme for WIA-PA networks. We present a selection approach for channel hopping sequence by considering the interference characteristic. Then we develop a novel channel assessment scheme. The detailed method combining the channel hopping scheme with WIA-PA superframe mechanism is also presented. The experimental results show that the proposed scheme can effectively improve the reliability of the system and is easy to implement in practical industrial wireless networks.
An evidence-based mobile decision support system for subaxial cervical spine injury treatment

Bringing evidence to practice is a key issue in modern medicine. The key barrier to information searching is time. Clinical decision support systems (CDSS) can improve guideline adherence. Mounting evidence exists that mobile CDSS on handheld computers support physicians in delivering appropriate care to their patients. Subaxial cervical spine injuries account for almost half of spine injuries, and a majority of spinal cord injuries. A valid and reliable classification exists, including evidence-based treatment algorithms. A mobile CDSS on this topic was not yet available. We developed and tested an iPhone application based on the Subaxial Injury Classification (SLIC) and 5 evidence-based treatment algorithms for the surgical approach to subaxial cervical spine injuries. The application can be downloaded for free. Users are cordially invited to provide feedback in order to direct further development and evaluation of CDSS for traumatic lesions of the spinal column.
‘Morbid tiers of immortality’: Don DeLillo'sPlayersand the financialisation of the USA

This article reads DeLillo's novel Players (1977) as an account of the transition from the 1970s’ capitalist crisis in the USA to what Greta Krippner calls ‘financialisation’. The process of ‘financialisation’ gave rise to a specific economic regime, social materiality, and a peculiar ‘structure of feeling’ grounded in finance capital. The protagonists of Players, Lyle and Pammy Wynant, participate in the fictitious vaporisation of social materiality that finance produces and structure their existences upon the workings of the medium of speculative capital in which they are immersed. I shall argue that the anxiety and dread pervading the Wynants can be interpreted as melancholia understood, following the theories of Abraham and Torok, as a ‘refusal to mourn’ and ‘incorporation’, and that such melancholia originates in the structural forgetting of the commodity form which is at the heart of the financial regime of accumulation. This essay aims to demonstrate that Players offers a powerful representation an...
Tipo de cambio real y balanza comercial: Condición Marshall-Lerner entre Ecuador y Estados Unidos (2000-2020)

Uno de los elementos fundamentales para el análisis de las interacciones de un país con el resto del mundo es el saldo de la balanza comercial. El presente artículo analiza el impacto del tipo de cambio real en la balanza comercial del Ecuador con respecto a Estados Unidos para el período 2000–2020. Los modelos implementados se basan en el análisis de elasticidad de la demanda de importaciones y exportaciones haciendo uso de datos mensuales y la metodología de cointegración de Johansen. Los resultados encontrados verifican la existencia de la condición Marshall-Lerner. Entonces, para el largo plazo se observan elasticidades poco superiores a la unidad en la ecuación de importaciones mientras que el coeficiente asociado con la tasa de cambio real bilateral resulta poco inferior a la unidad en la ecuación de exportaciones. En el corto plazo se registran grandes elasticidades, sin embargo, el ajuste realizado cada mes por el término de corrección de error es pequeño y al mismo tiempo el índice ecuatoriano de actividad económica no resulta estadísticamente significativo. Todo ello implica que una depreciación real puede mejorar la balanza comercial de Ecuador.
Experimental acoustic signal analyzed by the parametric and non parametric time-frequency representations

In this paper, we introduce the parametric and non parametric time-frequency representations for modeling non-stationary signals particularly the acoustic signals. The impulse response backscattered by Aluminium cylindrical shell, of radii ratio equal to 0.95, is analyzed from these time-frequency representations. The first representation is called spectrogram distribution SP and the second is the time-varying autoregressive spectrum TVAS. In this work we have chosen these two representations for these interesting properties. The SP and TVARS are applied to identify the circumferential waves, propagating around the circumference of the tube, and to determine the cut-off frequency of these waves. From the time-frequency images obtained, we have determined the cut-off frequencies. These frequencies are compared with those computed by the proper modes theory given in the scientific literature. A good agreement is obtained.
Nanoscale mechanical and tribological properties of fluorocarbon films grafted onto plasma-treated low-density polyethylene surfaces

Fluorocarbon (FC) films were grafted onto Ar plasma-treated low-density polyethylene (LDPE) surfaces by plasma polymerization and deposition. The evolution of the surface morphology of the grafted FC films was investigated at different scales with an atomic force microscope. Nanoscale sliding experiments performed with a surface force microscope provided insight into the nanotribological properties of Ar plasma-treated LDPE, with and without grafted FC films, in terms of applied normal load and number of sliding cycles. The observed trends are explained in the context of microstructure models accounting for morphological and structure changes at the LDPE surface due to the effects of plasma treatment (e.g., selective etching of amorphous phase, chain crosslinking and FC film grafting) and surface sliding (e.g., crystalline lamellae alignment along the sliding direction). Nanoindentation experiments elucidated the effect of plasma treatment on surface viscoelasticity and global contact stiffness. The results of this study demonstrate that plasma-assisted grafting of FC films is an effective surface modification method for tuning the nanomechanical/tribological properties of polymers.
ACTIVE FILTER TOPOLOGY FOR CASCADED INVERTERS

A method for generating a combined output waveform (VOUT ) in a power inverter system (100) is disclosed. The power inverter system comprises a voltage equaliser (120) having an energy storage element adapted to be charged by a combined output voltage from a plurality of switching units and to add an adjustable voltage to the combined output waveform. A voltage of the combined output waveform is measured, a difference (Δ) between the measured voltage of the output waveform and a voltage of a target waveform (UT ) is determined, and a voltage (UCORR ) corresponding to the determined difference is added, by the voltage equaliser, to the combined output waveform so as to improve the matching of the combined output power waveform and the target power waveform.
Hydrological cycle of the CADSES regions

The project HYDROCARE wishes to develop an integrated system capable of assessing the impact of hydrometeorological events on the water resources in the CADSES region. Emphasis will be put on the development of effective transnational tools for a rational exploitation of the water resources, with the purpose of preserving and enhancing economical and environmental welfare. Such managing tools will be illustrated also in practical terms by performing some case studies. Other main points of the project will be the reconstruction of the large and basin-scale hydrological cycle in the CADSES area, to be obtained by suitably merging observations (both local and remote) and models, and the development of a high level ICT network within a transnational frame for collecting and exchanging hydrometeorological data and providing relevant information to end-users such as professionals, farmers, entrepreneurs, public administrations and agencies.
Post-Crisis urban governance transformations in southern europe: a comparativist approach

The post-crisis transformations of the socio-political landscapes in Southern Europe have shaped crucial opportunities for emergent political actors and the civil society to introduce new governance mechanisms. Following a turbulent period of social mobilizations, rapid political and institutional transformations are underway at the city, regional and national levels in countries such as Spain and Greece, and particularly in Madrid and Athens. These provide a crucial theoretical, methodological and analytical challenge for urban studies and a key opportunity for the development of a novel relational comparative approach regarding the modifications of urban governance in Madrid and Athens. The prime research aim of URBANiTE is to investigate the ongoing socio-political developments in the two cities, the relationship between civil society and emergent political actors and the ways these shape institutional changes. The project will produce context-sensitive, innovative outcomes on multi-level territorial governance, of high relevance for science, society and policy, in times of sweeping challenges in Europe and beyond. Moreover, it involves integrated interdisciplinary research with policy implications for the governance of inclusive, innovative and reflective societies, hence fully responds to challenges set out in the Horizon 2020 Societal challenges programme. The Fellowship will provide opportunity for knowledge exchange, as the fellow will bring expertise from the UK and Greece on urban politics, citizenship and grassroots social innovation in austerity contexts. It will also allow the fellow to advance her knowledge in an interdisciplinary research environment and learn from a new regional context, which will contribute to greater understandings of urban governance changes, social innovation and policy implementation in contemporary Europe. Lessons generated will be of wider relevance for EU- level urban governance, with transferable outcomes to other contexts.
Brief Report: Childhood Disintegrative Disorder: A Brief Examination of Eight Case Studies

Childhood disintegrative disorder (CDD) is a rare condition characterized by distinct regression of developmental and behavioral functioning following a period of apparently normal development for at least 2 years. The purpose of this article is to present the developmental, behavioral, psychosocial, and medical histories of eight children who have been diagnosed with CDD in an attempt to advance the understanding of this rare disorder. Results indicate the average age of onset was 3.21 years. Three cases reported an insidious onset while two cases exhibited acute onset. Developmental and behavioral milestones were met at age appropriate times in each case and significant deterioration of formerly acquired skills and abnormalities in functioning were clinically present in all eight cases.
SUSPENSION DEGASSING

The invention relates to a device for degassing a fibrous material suspension (1) in a closed degassing space (2) having at least one feed (3) through which the fibrous material suspension (1) is introduced, wherein the fibrous material suspension (1) collects in the lower part of the degassing space (2), the degassing space (2) is connected above the suspension level (4) of the collecting fibrous material suspension (1) to a reduced pressure source (5) which sucks out the gas that has been separated out, at least one outlet (6) which is beneath the suspension level (4) and removes the degassed fibrous material suspension (1), and an overflow present between the feed (3) and outlet (6) at the height of the suspension level (4), wherein the feed (3), overflow and outlet (6) are each spaced apart horizontally from one another. In this context, the extent of the degassing space (2) and hence also of the material expenditure are to be reduced, without impairing the function, by forming the overflow from at least one elongated overflow channel (7) which runs transverse to the flow direction of the fibrous material suspension (1) between the feed (3) and outlet (6) and is open at the top.
"Até que todas sejamos livres": o ativismo 'sentipensado' das feministas agroecológicas brasileiras contra as violências agrocapitalistas

A autora analisa as mobilizações agroecológicas feministas no Brasil a partir das conceitualizações do "sentipensar" e do corazonar. O vínculo com a Terra e a fusão entre emoções e análise política são analisadas através do estudo de materiais ativistas (mística, canções, poemas, slogans) e entrevistas com ativistas rurais. A compreensão deste sentipensamento lança luz sobre as diferentes dimensões da violência. É proposta uma análise da violência de gênero, entendida como uma estratégia do agrocapital. Violência conjugal e "feminicídios agrocapitalistas" fazem parte do que a autora chama de "necropolítica agrocapitalista". As estratégias coletivas de superação usadas pelas ativistas favorecem uma afirmação de força e uma continuidade da luta e da vida
El (des)exilio de Victoria Kent. Una republicana irredenta frente a la transición democrática española

Victoria Kent (Malaga, 1892 – Nueva York, 1987) fue una de las pocas mujeres que ejercieron funciones politicas de primer plano durante la Segunda Republica. Hasta su muerte en Estados Unidos, pais en el que vivio la mayor parte de su exilio, continuo su actividad militante, a traves de la revista Iberica. Por la libertad (1953-1974) y su compromiso en la Accion Republicana Democratica Espanola (ARDE), partido legalizado demasiado tardiamente como participar en las elecciones de 1977. 
Este capitulo vuelve sobre la expresion de este compromiso politico frente al proceso de Transicion democratica en Espana. Aunque fuese discreta, esta actuacion ofrece una perspectiva interesante sobre los dos problemas fundamentales vinculados a la cuestion del retorno de los exiliados: la dificultad vital de su reingreso a un pais profundamente transformado despues de cuatro decadas de dictadura, y la integracion del proyecto republicano que encarnaban los exiliados al modelo de Estado disenado durante la Transicion. Prueba de estas dificultades es la negativa de Victoria Kent a permanecer en Espana, y su regreso definitivo a Nueva York. 
A partir de los pocos articulos que publico la ex ministra en la prensa espanola; de extractos de su correspondencia con algunos de sus companeros de lucha politica e intelectual; y de un repaso de las reacciones que suscito su retorno incompleto a Espana, esta comunicacion propondra una reflexion sobre el triple obstaculo que suponia en aquel momento el hecho de ser mujer, exiliada y republicana de cara a una integracion en la vida politica espanola.
RePaLi participation to CLEF eHealth IR challenge 2014: leveraging term variation

This paper describes the participation of RePaLi, a team composed with members of IRISA, LIMSI and STL, to the biomedical information retrieval challenge proposed in the framework of CLEF eHealth. For this first participation, our approach relies on a state-of-the-art IR system called Indri, based on statistical language modeling, and on semantic resources. The purpose of semantic resources and methods is to manage the term variation such as synonyms, morpho-syntactic variants, abbreviation or nested terms. Different combinations of resources and Indri settings are explored, mostly based on query expansion. For the runs submitted, our system shows up to 67.40 p@10 and up to 67.93 NDCG@10.
Influence of Indium Tin Oxide Surface Treatment on Spatially Localized Photocurrent Variations in Bulk Heterojunction Organic Photovoltaic Devices

A correlation between anode surface treatment and spatially localized photocurrent variations has been found in bulk heterojunction poly(3-hexylthiophene):[6,6]-phenyl-C-61-butyric acid methyl ester (P3HT:PCBM) organic photovoltaic (OPV) devices. Atomic force photovoltaic microscopy was used to scan arrays of 2 μm diameter OPV devices with varied indium tin oxide (ITO) surface treatments. The standard deviation of the average photocurrent was found to be 11.4% for devices fabricated on untreated ITO, 8.6% for devices with a poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) interlayer, and 6.7% for devices with a HCl-treated ITO surface. These results suggest that spatial variations in the structure and electronic properties of the anode surface degrade the overall performance of OPVs, including reductions in short-circuit current by up to 20%, thus highlighting the importance of surface treatments that improve the homogeneity of ITO.
Assessment of bioaerosols at a concentrated dairy operation

Increased bioaerosol loadings in down- wind plumes from concentrated animal feeding oper- ations (CAFOs) may increase the risk for allergy and infection in humans. In this study, we monitored airborne concentrations of culturable bacteria and fungi at upwind (background) and downwind sites at a 10,000 milking cow dairy over the course of a year. The average bacterial concentrations at the upwind site were 8.4 9 10 3 colony forming units (CFU) m -3 and increased to 9.9 9 10 5 CFU m -3 at the down- wind edge of the cattle lots, decreasing to 6.3 9 10 4 CFU m -3 200 m farther downwind. At the same sites, the average fungal concentrations were 515, 945, and 1,010 CFU m -3 , respectively. Significant correla- tions between the ambient weather conditions and airborne fungal and bacterial concentrations were identified. Sequence analysis of PCR-amplified DNA from bacterial clones and fungal isolates revealed genus and species level differences between upwind and downwind sites. Although we could not cultivate gram-negative bacteria, bacterial clones at downwind sites identified as being gram-negative matched with the following genera: Acinetobacter, Bradyrhiz- obium, Escherichia, Idiomarina, Methylobacterium, Ralstonia, and Novosphingobium. Fungal isolates from downwind matched with the following genera: Acremonium, Alternaria, Ascomycte, Aspergillus, Basidiomycete, Cladosporium, Davidiella, Doratomy- ces, Emericella, Lewia, Onygenales, Penicillium, Rhizopus, and Ulocladium. None of the bacterial and fungal sequence matches were affiliated with genera and species known to be pathogenic to humans. Overall, the data suggest that exposure to bioaerosols in the downwind environment decreases with increas- ing distance from the open-lot dairy.
IMPROVEMENTS IN AND RELATING TO AN INJECTION DEVICE

Injection devices are known for the self administration of a medicament by patients. The medicament is typically contained within a cartridge located within an injection device. It is a problem that injection devices should be small enough to fit into a jacket pocket or a hand bag without difficulty. Concurrently, the injection device must be of a size that enables a piston used to drive a cartridge bung within the cartridge to both to a maximum dispense position within the cartridge and to be fully withdrawn from the cartridge to allow for replacement of the cartridge. A drive mechanism for an injection device is disclosed comprising a piston member (10), a semi rigid belt (12) connected at a first end to the piston member (10), a belt drive means to drive the semi rigid belt (12) and a dose setting mechanism to control the driving of the semi rigid belt (12) in which the belt drive means comprises a first cable means (22) connected at a first end to a second end of the semi rigid belt (12) and at a second end to a first spool (24). An injection device comprising such a drive mechanism is also disclosed.
Synthesis and spark plasma sintering of sub-micron HfB2: Effect of various carbon sources

Abstract The present work describes a simple process to synthesise HfB 2 powder with sub-micron sized particles. Hafnium chloride and boric acid were used as the elemental sources whilst several carbon sources including sucrose, graphite, carbon black, carbon nanotubes and liquid and powder phenolic resin were used. The carbon sources were characterised using thermogravimetric analysis and transmission electron microscope. The mechanism by which the structure of the carbon source used, affects the size and morphology of the resultant HfB 2 powder was studied; the HfB 2 powders were characterised using X-ray diffraction and scanning and transmission electron microscopy. The powder synthesised using powder phenolic resin had a surface area of 21 m 2  g −1 and a particle size distribution between 30 and 150 nm. This was sintered using SPS to a relative density of 94% of theoretical density (TD) at 2100 °C and 50 MPa pressure without the help of any sintering aids.
