Mass Transfer in Two Post-AGB Binaries with Dusty Disks
Authors: Gorlova N. , Van Winckel H. , Jorissen A. 
Published: March 2017

Abstract
We present a time series of high-resolution spectra for two poorly studied candidate post-AGB stars surrounded by dusty disks, BD+46 442 and IRAS 19135+3937. We find that both stars show radial velocity variations with periods of 130-140 days. IRAS 19135+3937 has been previously classified as a semi-regular variable based on the light variations with a similar period, but our spectra reveal an evolved star which is too warm to be on the AGB. the variability of BD+46 442 has not been studied till now. the stars reveal a number of spectroscopic peculiarities that resemble features in the interactive binaries including the S-type Symbiotics. Namely, H profile alternates between a double-peak emission and a P Cyg profile, which correlates with the radial velocity phase. A weak asymmetry is tentatively detected in the cross-correlation function that moves in anti-phase with the main component. In addition, strong photospheric lines reveal a narrow central absorption. We conclude that these peculiarities are consistent with a picture where the observed post-AGB stars orbit a much fainter companion at a sub-AU separation and transfer mass on it. the companion is surrounded by an accretion disk, possibly with some kind of an outflow. the SED shows that whole system is surrounded by stable dusty disk as well. It remains to be seen with more observations how much of the line asymmetry could be due to the contribution of low-amplitude pulsations.
Reconstructing Historical Light Curves of Symbiotic Stars and Novae
Authors: Jurdana-Šepić R. , Munari U. 
Published: March 2017

Abstract
We reconstructed photometric histories of symbiotic stars and novae from direct inspection and measurement of photographic plates preserved at historical archives. We have completed the digging of the rich Asiago archive, and have started working on the Harvard plate stack, while other plate collections should be added soon. For homogeneity, we use the same UBV RCIC photometric comparison sequences used in current CCD observations. This data harvest has permitted the discovery of past undetected outbursts and secular trends, or to derive previously unknown orbital periods and recurrence times, which are essential to constrain the nature of these capricious and variegated active binaries.

Published: March 2017

Abstract
We are intensively monitoring the current outburst on BF Cyg, both spectroscopically (high and low resolution modes) and photometrically (so far 450 BV RCIC measurements have been collected). the outburst is photometrically reminiscent of the major event BF Cyg experienced in 1890 when it rose by 4 mag in the blue. In this contribution we present the data and describe the plans to investigate this object.

Multiband Study of Radio Sources of the RCR Catalogue with Virtual Observatory Tools
Authors: Zhelenkova O. P. , Soboleva N. S. , Majorova E. K. , Temirova A. V. 
Published: March 2017

Abstract
We present early results of our multiband study of the RATAN Cold Revised (RCR) catalogue obtained from seven cycles of the “Cold” survey carried with the RATAN-600 radio telescope at 7.6 cm in 1980-1999, at the declination of the SS 433 source. We used the 2MASS and LAS UKIDSS infrared surveys, the DSS-II and SDSS DR7 optical surveys, as well as the USNO-B1 and GSC-II catalogues, the VLSS, TXS, NVSS, FIRST and GB6 radio surveys to accumulate information about the sources. For radio sources that have no detectable optical candidate in optical or infrared catalogues, we additionally looked through images in several bands from the SDSS, LAS UKIDSS, DPOSS, 2MASS surveys and also used co-added frames in different bands. We reliably identified 76% of radio sources of the RCR catalogue. We used the ALADIN and SAOImage DS9 scripting capabilities, interoperability services of ALADIN and TOPCAT, and also other Virtual Observatory (VO) tools and resources, such as CASJobs, NED, Vizier, and WSA, for effective data access, visualization and analysis. Without VO tools it would have been problematic to perform our study.
A forecasting performance comparison of dynamic factor models based on static and dynamic methods
Authors: Marra Fabio Della 
Published: March 2017

Abstract
We present a comparison of the forecasting performances of three Dynamic Factor Models on a large monthly data panel of macroeconomic and financial time series for the UE economy. The first model relies on static principal-component and was introduced by Stock and Watson (2002a, b). The second is based on generalized principal components and it was introduced by Forni, Hallin, Lippi and Reichlin (2000, 2005). The last model has been recently proposed by Forni, Hallin, Lippi and Zaffaroni (2015, 2016). The data panel is split into two parts: the calibration sample, from February 1986 to December 2000, is used to select the most performing specification for each class of models in a in- sample environment, and the proper sample, from January 2001 to November 2015, is used to compare the performances of the selected models in an out-of-sample environment. The metholodogical approach is analogous to Forni, Giovannelli, Lippi and Soccorsi (2016), but also the size of the rolling window is empirically estimated in the calibration process to achieve more robustness. We find that, on the proper sample, the last model is the most performing for the Inflation. However, mixed evidencies appear over the proper sample for the Industrial Production.

On the number of functions of k-valued logic which are polynomials modulo composite k
Authors: Selezneva Svetlana N. 
Published: March 2017

Abstract
A function of k-valued logic is called polynomial if it may be represented by a polynomial modulo k. For any composite number k we propose a uniquely defined canonical form of polynomials for polynomial functions of k-valued logic depending on an arbitrary number of variables. This canonical form is used to find, for any composite k, a formula for the number of n-place polynomial functions of k-valued logic. As a corollary, for any composite k we find the asymptotic behaviour of the logarithm of the number of n-place polynomial functions of k-valued logic.

Abstract
We obtain new upper bounds for the size and the depth of formulae for some MOD-functions (that is, functions counting n bits modulo m). In particular, the depth of counting n bits modulo 3 is bounded by 2.8 log2
n + O(1) in the standard basis {Λ, V,—}; the size of counting modulo 5 is bounded by O(n
3.22) in the same basis; the depth of counting modulo 7 is bounded by 2.93 log2
n+O(1) in the basis of all binary Boolean functions.
Macroporous polymer beads derived from a novel coporogen of polyethylene/dichlorobenzene
Authors: Liang Kai , Li Gen , Peng Meixuan , Liu Qingquan 
Published: March 2017

AbstractMacroporous poly(divinylbenzene) (PDVB) beads were prepared by traditional suspension polymerization in the presence of dichlorobenzene (DCB) and polyethylene (PE) as coporogen. Two types of PE with different molecular weights were used as polymer porogen, and the weight percent of PE in DCB varied from 0 to 8.0 wt%. Effects of PE concentration and PE molecular weight on the pore structure of PDVB beads were investigated. As expected, the highest surface area was achieved by the beads prepared with DCB as the sole porogen. Applying coporogen with PE with low molecular weight (LPE) content, the surface area of PDVB beads declined because of early phase separation induced by the cooperation of LPE and DCB. However, the value increased abruptly when 5 wt% LPE in DCB was used as coporogen. Subsequently, the values again decreased when LPE amount further increased. Overall, the molecular weight of PE and the concentration of PE in coporogen had a significant effect on the pore structure and surface morphology of PDVB beads.
Research Article. Towards a tidal loading model for the Argentine-German Geodetic Observatory (La Plata)

Published: March 2017

Abstract
We present a regionalized model of ocean tidal loading effects for the Argentine-German Geodetic Observatory in La Plata. It provides the amplitudes and phases of gravity variations and vertical deformation for nine tidal constituents to be applied as corrections to the observatory’s future geodetic observation data. This model combines a global ocean tide model with a model of the tides in the Río de la Plata estuary. A comparison with conventional predictions based only on the global ocean tide model reveals the importance of the incorporation of the regional tide model. Tidal loading at the observatory is dominated by the tides in the Atlantic Ocean. An additional contribution of local tidal loading in channels and groundwater is examined. The magnitude of the tidal loading is also reviewed in the context of the effects of solid earth tides, atmospheric loading and non-tidal loads.
Multimodal Construction Grammar issues are Construction Grammar issues
Authors: Schoonjans Steven 
Published: March 2017

Abstract
If multimodal work in terms of Construction Grammar is still rare nowadays, this is not just because the upsurge of multimodality in linguistics in general is rather recent. Attempts to include non-verbal layers of expression (especially gesture) in Construction Grammar have uncovered a number of theoretical issues that need to be reflected upon before any serious claims on the existence of multimodal constructions can be made. While some scholars take these issues as reasons for leaving the non-verbal outside of the scope of Construction Grammar, this paper shows that several of these issues are not actually related to multimodality, but rather hint at more general theoretical issues in Construction Grammar. Hence, it is argued that these issues should be seen as an incentive for rethinking and refining the notion of ‘construction’, rather than as a reason for leaving multimodality aside.
The “Negative-Assessment-Construction” – A multimodal pattern based on a recurrent gesture?
Authors: Bressem Jana , Müller Cornelia 
Published: March 2017

Abstract
This paper offers an analysis of a multimodal pattern of negative assessment, which takes as the starting point a particular recurrent gesture: the Throwing Away gesture. Recurrent gestures are characterized by a stabilized form-meaning pairing. In the case of the Throwing Away gesture, form and meaning are grounded in an “Away-Action-Scheme”: i. e., a socially shared, sedimented experience of removing unwanted objects at, on, or approaching a speaker’s body. Based on a cognitive-linguistic analysis of the gesture and its use in five different verbal contexts, we suggest that the Throwing Away gesture enters a verbo-kinesic construction that consists of the “Throwing Away Gesture + particles/negation/N/V/ADV”. The meaning of the verbo-kinesic construction is grounded in an embodied frame of experience in Fillmore’s sense: i. e., a schematized scene involving mundane actions, here ‘removals of unwanted objects’ (e. g., ‘Away-Action-Scenes’). Referring to Goldberg’s “Scene Encoding Hypothesis”, we propose that the “Negative-Assessment-Construction” designates scenes essential to human experience. With this focus, the paper puts forward a gesture-first account on verbo-kinesic constructions and suggests a possible candidate for such a multimodal pattern.
Do we really need a Multimodal Construction Grammar?
Authors: Ziem Alexander 
Published: March 2017

Abstract
A multimodal construction is said to be a conventional pairing of a complex form, comprising at least a verbal and a kinetic element, with a specific meaning or a specific function. Do we need a new constructional approach to account for such multimodal constructions? What are the challenges to account for multimodality? The aim of this contribution is to provide a precise notion ‘multimodal construction’ and, on this basis, to indicate possible pathways for future investigations. The paper opts for cautiously extending the scope of existing constructional approaches in order to include non-linguistic meaningful behavior. In particular, it is argued that even though Construction Grammar invites for treating multimodal on a par with linguistic constructions, there is a huge lack of substantial empirical support to arrive at a more detailed and data-based understanding of the nature of multimodal constructions.

Published: March 2017

Habituation is a basic form of implicit learning and represents a sensory filter that is disrupted in autism, schizophrenia, and several other mental disorders. Despite extensive research in the past decades on habituation of startle and other escape responses, the underlying neural mechanisms are still not fully understood. There is evidence from previous studies indicating that BK channels might play a critical role in habituation. We here used a wide array of approaches to test this hypothesis. We show that BK channel activation and subsequent phosphorylation of these channels are essential for synaptic depression presumably underlying startle habituation in rats, using patch-clamp recordings and voltage-sensitive dye imaging in slices. Furthermore, positive modulation of BK channelsin vivocan enhance short-term habituation. Although results using different approaches do not always perfectly align, together they provide convincing evidence for a crucial role of BK channel phosphorylation in synaptic depression underlying short-term habituation of startle. We also show that this mechanism can be targeted to enhance short-term habituation and therefore to potentially ameliorate sensory filtering deficits associated with psychiatric disorders.SIGNIFICANCE STATEMENTShort-term habituation is the most fundamental form of implicit learning. Habituation also represents a filter for inundating sensory information, which is disrupted in autism, schizophrenia, and other psychiatric disorders. Habituation has been studied in different organisms and behavioral models and is thought to be caused by synaptic depression in respective pathways. The underlying molecular mechanisms, however, are poorly understood. We here identify, for the first time, a BK channel-dependent molecular synaptic mechanism leading to synaptic depression that is crucial for habituation, and we discuss the significance of our findings for potential treatments enhancing habituation.
Proteomics and integrative omic approaches for understanding host–pathogen interactions and infectious diseases
Authors: Jean Beltran Pierre M , Federspiel Joel D , Sheng Xinlei , Cristea Ileana M 
Published: March 2017

AbstractOrganisms are constantly exposed to microbial pathogens in their environments. When a pathogen meets its host, a series of intricate intracellular interactions shape the outcome of the infection. The understanding of these host–pathogen interactions is crucial for the development of treatments and preventive measures against infectious diseases. Over the past decade, proteomic approaches have become prime contributors to the discovery and understanding of host–pathogen interactions that represent anti‐ and pro‐pathogenic cellular responses. Here, we review these proteomic methods and their application to studying viral and bacterial intracellular pathogens. We examine approaches for defining spatial and temporal host–pathogen protein interactions upon infection of a host cell. Further expanding the understanding of proteome organization during an infection, we discuss methods that characterize the regulation of host and pathogen proteomes through alterations in protein abundance, localization, and post‐translational modifications. Finally, we highlight bioinformatic tools available for analyzing such proteomic datasets, as well as novel strategies for integrating proteomics with other omic tools, such as genomics, transcriptomics, and metabolomics, to obtain a systems‐level understanding of infectious diseases.
Isolados e ilhados: indigenismo e conflitos no Vale do Javari, Amazônia
Authors: Arisi Barbara , Milanez Felipe 
Published: March 2017

Nesse artigo, pretendemos mostrar como um certo ideal de índio permeia as utopias indigenistas do Estado brasileiro e como a política de isolamento, influenciada por esses ideais, apresenta suas idiossincrasias e contradições. Apresentamos um estudo sobre os conflitos recentes na Terra Indígena Vale do Javari (AM) que levaram à morte violenta de índios Korubo e Matis, considerados pelo governo respectivamente como “isolados” e de “recente contato”. Analisamos a história do conflito a partir das narrativas indigenistas e dos indígenas. Observamos as formas como os servidores da FUNAI procuram ignorar e negar o direito à autodeterminação indígena e como procuram obliterar o papel e a presença do Estado nas relações interétnicas na região. Concluimos que um possível diálogo parece ser o primeiro passo para pôr fim a uma política de “índios ignorados”. O ideal de isolamento não pode se sobrepor à auto-determinação: o conceito é fragilmente sustentado em uma ideia romântica e contraditória de índios que vivem totalmente à margem de processos históricos, como se não sofressem e reagissem às pressões do velho (neo)desenvolvimento promovido pelo Estado e pela presença de frentes expansionistas como madeireiros, construtoras de barragens ou petroleiras.
A reforma agrária assistida pelo mercado do Banco Mundial na África do Sul e no Brasil (1994-2002)
Authors: Pereira João Márcio Mendes 
Published: March 2017

O artigo analisa a “reforma agrária assistida pelo mercado” (RAAM) do Banco Mundial, abordando a sua racionalidade, a agenda política da qual fez parte e os resultados da sua implantação na África do Sul e no Brasil. Após identificá-la ao processo mais amplo de atualização da agenda neoliberal articulado em meados dos anos 1990, o artigo discute o programa agrário do Banco e detalha os seus componentes, entre os quais a RAAM. Em seguida, resume tanto a crítica do Banco às reformas agrárias redistributivas do passado, baseadas na desapropriação de terras pelo Estado, como as supostas vantagens da RAAM. Também discute a intencionalidade política que orientou a sua implementação e analisa os resultados socioeconômicos e políticos da RAAM nos dois países.
A fogyókúrák buktatói – pszichés tényezők
Authors: Resch Mária 
Published: March 2017

Abstract: Introduction: Eating is one of the fundamental sources of happiness. Slimming diets would deprive you of this very enjoyment without granting something else instead, for example, proper eating behaviours for life or a permanent solution for overweight-related problems. Aim: This paper aims to investigate the psycho-dynamic relationships that might be the reason for the failure of all diets and slimming diets. Method: Analysing overweight, obesity and the failure of slimming diets with the help of the cognitive behavioral therapeutic approach. Results: By applying the principles confirmed and laid down by the cognitive behavioral therapy, we can identify specific ethological causes present in dieting and gaining weight behaviours that can successfully be used in curative symptom and problem oriented psychotherapy. Conclusion: In summary it can be stated that it is advised to approach the defined objective slowly, in small steps. With the help of learning methods and the continual transformation of the environment, obese individuals, having shred their own unwanted behavioral attitudes, can not only build up new attitudes and transform them into new desirable habits but will also have their personalities chiselled.
