Published: June 2016

AbstractBackgroundLeft ventricular assist devices (LVADs) have become an increasingly popular and effective means for treating advanced heart failure. LVAD implantation requires extensive surgery and postoperative rehabilitation. The Functional Independence Measure (FIM) has been used to quantify functional gains in numerous patient populations, including those with stroke and spinal cord injury. This study investigated functional improvements in patients undergoing LVAD implantation using the FIM score.ObjectiveTo assess functional improvements in patients with advanced heart failure who underwent LVAD implantation.DesignRetrospective.SettingInpatient rehabilitation unit.SubjectsNinety consecutive patients who received acute inpatient rehabilitation after continuous flow LVAD implantation.MethodsDemographic, laboratory, and functional outcomes data including inpatient rehabilitation unit (IRU) length of stay (LOS), discharge disposition, and FIM score were collected for all patients. Paired t‐tests were used to assess change in functional measures and laboratory data.Main Outcome MeasuresPrimary outcome measures included FIM gain, FIM efficiency, discharge disposition, rates of readmission after discharge from rehabilitation, and LOS in the rehabilitation unit.ResultsThe FIM gain was statistically significant at 28.4 ± 12.3 (P < .001) and compared favorably with benchmarks for mean FIM gains at our facility (26.4), regionally (21.5), and nationally (22.7) for patients admitted to IRUs with a cardiac diagnosis. FIM efficiency (FIM gain/IRU LOS) was 1.9 ± 1.0 compared with the mean FIM efficiency at our facility (2.2), regionally (2.1), and nationally (2.2). Seventy‐four percent (n = 67) of patients were discharged directly home after inpatient rehabilitation, 17% (n = 16) were readmitted to the acute hospital service, and 8% (n = 7) required additional rehabilitation at a subacute rehabilitation facility. The IRU LOS was 16.2 ± 6.9 days.ConclusionsOur study indicates that most patients with an LVAD achieve clinically meaningful functional gains from acute inpatient rehabilitation, with the majority of patients being discharged home. Further studies need to be performed to analyze clinical outcomes after acute inpatient rehabilitation.Level of EvidenceIV
The effect of shear-thinning behaviour on rod orientation in filled fluids

Published: June 2016

In the present article, the cell model (or self-consistent scheme) is used to derive constitutive equations for rod suspensions in non-Newtonian viscous matrices such as power-law, Ellis and Carreau fluids. It is found that the shear-thinning character of the matrix influences considerably the rod contribution to the stress tensor, but has no impact on the rod orientation dynamics: the same microstructure evolution as the one encountered in Newtonian fluids is obtained. The rod suspension behaves differently than the unfilled matrix in the sense that, depending on rod orientation, the onset of shear thinning in the composite occurs at lower or higher shear rates. Our analysis also provides a semi-analytical model for rod suspensions in an Ellis fluid, which appears to be suitable for predicting a Newtonian plateau at low shear rates and a shear-thinning behaviour at high shear rates. In addition, the model predictions are in good agreement with the shear viscosity measurements of glass-fibre-filled polystyrene melts (Chan et al., J. Rheol., vol. 22 (5), 1978, pp. 507–524), demonstrating its ability to describe the rheological behaviour of such polymer composites. Finally, the proposed approach is extended to a Carreau fluid although its solution requires the numerical solution of a set of partial differential equations.

AbstractThe objective of this study was to investigate the effects ofl-carnitine and/or maize distillers dried grains with solubles (DDGS) in diets of gestating and lactating sows on the intestinal barrier functions of their offspring. The experiment was designed as a 2×2 factorial with two dietary treatments (soyabean mealv.DDGS) and twol-carnitine levels (0v.100 mg/kg in gestating diets and 0v.200 mg/kg in lactating diets). Sows (Landrace×Large White) with an average parity of 4·2 with similar body weight were randomly assigned to four groups of thirty each. Dietary supplementation withl-carnitine increased the total superoxide dismutase activity but decreased the concentration of malondialdehyde of the jejunal mucosa in newborn piglets and weaning piglets on day 21. Dietary supplementation withl-carnitine decreased the concentrations of IL-1β, IL-12 and TNF-αin the jejunal mucosa of newborn piglets and decreased the concentrations of IL-6 and TNF-αin the jejunal mucosa of weaning piglets on day 21. There was an interaction between dietary treatment andl-carnitine on the bacterial numbers of total eubacteria in the digesta of caecum in weaning piglets on day 21. Bacterial numbers of total eubacteria in weaning piglets on day 21 were significantly increased byl-carnitine only in soyabean meal diet, but there was no significant effect ofl-carnitine in DDGS-based diet. Dietary supplementation withl-carnitine increased the bacterial numbers ofLactobacillusspp. and bifidobacteria spp. in the digesta of caecum in weaning piglets on day 21. Dietary supplementation withl-carnitine in sows affected the expression of tight junction proteins (claudin 1, zonula occludens-1 (ZO-1) and occludin) in the jejunal mucosa of their offspring by increasing the expression of ZO-1 mRNA in the jejunal mucosa of newborn piglets, and by increasing the expression of ZO-1 and occludin mRNA in the jejunal mucosa of weaning piglets on day 21. In conclusion, dietary supplementation withl-carnitine in gestating and lactating sows had positive effects on intestinal barrier functions of newborn piglets and weaning piglets on day 21, but it did not have effects on intestinal barrier functions of growing–finishing pigs in the filial generation. There were no effects of dietary treatment of sows on intestinal barrier functions in their offspring.
CONTRASTING CONCURRENT AND CHILDHOOD SOCIOECONOMIC PREDICTORS OF SELF-RATED HEALTH AMONG OLDER EUROPEAN MEN AND WOMEN
Authors: Verropoulou Georgia , Zakynthinou Maria 
Published: June 2016

SummaryThis study aimed to assess the relative importance of childhood and adulthood socioeconomic position (SEP) on the self-rated health (SRH) of men and women aged 50 or higher in Europe, controlling for a substantial number of mediators and health conditions. Data from Wave 2 (current data) and Wave 3 (retrospective material) of the Survey of Health, Ageing and Retirement in Europe (SHARE) were combined (N=20,829) and logistic regression models applied; the analysis was carried out for males and females separately. The findings indicate that concurrent and past SEP, when considered separately, are both very significant predictors of SRH. When all factors were included in a comprehensive model most childhood and adult SEP variables retained their significance, implying that both types of socioeconomic circumstances have a strong and independent effect on SRH. However, the relative importance of several childhood indicators was reduced, signifying that their effect on SRH is mediated by adult SEP and, especially, educational attainment. Some childhood predictors, such as having experienced a period of hunger, remained very significant. Though these findings roughly hold for both sexes, the relative effects differentiate by sex. Current SEP is more important among women, with the exception of income and ‘making ends meet in the household’. Childhood SEP indicators are more significant among men.
Many important language universals are not reducible to processing or cognition
Authors: Medeiros David P. , Piattelli-Palmarini Massimo , Bever Thomas G. 
Published: June 2016

AbstractChristiansen & Chater (C&C) ignore the many linguistic universals that cannot be reduced to processing or cognitive constraints, some of which we present. Their claim that grammar is merely acquired language processing skill cannot account for such universals. Their claim that all other universal properties are historically and culturally based is a nonsequitur about language evolution, lacking data.
Is Now-or-Never language processing good enough?
Authors: Ferreira Fernanda , Christianson Kiel 
Published: June 2016

AbstractChristiansen & Chater's (C&C's) Now-or-Never bottleneck framework is similar to the Good-Enough Language Processing model (Ferreira et al. 2002), particularly in its emphasis on sparse representations. We discuss areas of overlap and review experimental findings that reinforce some of C&C's arguments, including evidence for underspecification and for parsing in “chunks.” In contrast to Good-Enough, however, Now-or-Never does not appear to capture misinterpretations or task effects, both of which are important aspects of comprehension performance.
Natural language processing and the Now-or-Never bottleneck
Authors: Gómez-Rodríguez Carlos 
Published: June 2016

AbstractResearchers, motivated by the need to improve the efficiency of natural language processing tools to handle web-scale data, have recently arrived at models that remarkably match the expected features of human language processing under the Now-or-Never bottleneck framework. This provides additional support for said framework and highlights the research potential in the interaction between applied computational linguistics and cognitive science.
How long is now? The multiple timescales of language processing
Authors: Honey Christopher J. , Chen Janice , Müsch Kathrin , Hasson Uri 
Published: June 2016

AbstractChristiansen & Chater (C&C) envision language function as a hierarchical chain of transformations, enabling rapid, continuous processing of input. Their notion of a “Now-or-Never” bottleneck may be elaborated by recognizing that timescales become longer at successive levels of the sensory processing hierarchy – that is, the window of “Now” expands. We propose that a hierarchical “process memory” is intrinsic to language processing.
What is the value of security? Contextualising the negative/positive debate
Authors: Nyman Jonna 
Published: June 2016

AbstractReview of International Studieshas seen a debate over thevalueof security. At its heart this is a debate about ethics: concerning the extent to which security is a ‘good’ and whether or not security politics produces the kind of world we want. More recent contributions focus on the extent to which security is ‘positive’ or ‘negative’. However, this article argues that the existing debate is limited and confusing: key authors use the terms ‘positive’ and ‘negative’ in different, and, at times, contradictory ways. The article clarifies the roots of the existing debate, and then draws out two different uses of the terms positive and negative: an analytic frame and a normative frame. In response, it proposes a pragmatist frame that synthesises the existing uses, drawing on pragmatism and practice-centred approaches to analyse the value of security in context. The contribution of the article is thus twofold: it both clarifies the existing debate and suggests a solution. This is key because the debate over the value of security is crucial to thinking about how we want to live.
Visual regimes and the politics of war experience: Rewriting war ‘from above’ in WikiLeaks’ ‘Collateral Murder’
Authors: Tidy Joanna 
Published: June 2016

AbstractWar experiences are a material of political currency, invoked, appropriated, and ‘written’ in particular configurations to sustain, complicate, and contest narratives about war. This occurs through and within the same relations of power that are intrinsic to the conduct of war as war-experiencing subjects comprise a political vocabulary of selves and others that populate and operate within war’s wider social (re)production. To track these power relations and consider implications for how dominant accounts of war can be complicated and contested, the article is grounded in an analysis of the visual regimes at work in footage, photographs, and testimony relating to the shooting of a group of people by an American Apache helicopter in Baghdad, Iraq in 2007. The event was publicised on a dedicated website and dubbed ‘Collateral Murder’ by WikiLeaks in 2010. Analysis of the website reveals how visual modes and the experiences of war subjects accompany each other, revealing war in contrasting locations of sight and violence: the ‘view from above’, the ‘view from below’, and the view of the ‘on-the-ground’ soldier eyewitness. Taken together these discursively produce ‘Collateral Murder’ and contest the dominance of war known through the experience of those who wage it ‘from above’.
Traceless SU(2) representations of 2-stranded tangles
Authors: FUKUMOTO YOSHIHIRO , KIRK PAUL , PINZÓN-CAICEDO JUANITA 
Published: June 2016

AbstractGiven a 2-stranded tangle T contained in a ℤ-homology ball Y, we investigate the character variety R(Y, T) of conjugacy classes of traceless SU(2) representations of π1(Y \ T). In particular we completely determine the subspace of binary dihedral representations, and identify all of R(Y, T) for many tangles naturally associated to knots in S3. Moreover, we determine the image of the restriction map from R(T, Y) to the traceless SU(2) character variety of the 4-punctured 2-sphere (the pillowcase). We give examples to show this image can be non-linear in general, and show it is linear for tangles associated to pretzel knots.
MAYA FLASKS: THE “HOME” OF TOBACCO AND GODLY SUBSTANCES
Authors: Loughmiller-Cardinal Jennifer A. , Zagorevski Dmitri 
Published: June 2016

AbstractAmong the specialized types of Late Classic Maya vessels (a.d.550–900) are small bottle-shaped containers known as “flasks.” Current interpretations of their uses, for example as poison bottles or medicine bottles, are speculative. In some cases, such interpretations rely on analogical comparisons with other Native American containers based on their formal similarities of shape or construction. This paper presents research on basic construction methods of flasks, a set of correlations between the various social mediation roles in which such flasks are depicted in Classic-period artwork, their material correlates (the vessels themselves), and a report of their specific contents. We also provide evidence of the first discovery of nicotine in an ancient Maya vessel, which is the first empirically demonstrated proof for the presence of tobacco contained in a clay vessel from this cultural tradition. The codex-style flask yielding this evidence bears a text that appears to readyo-'OTOT-ti 'u-MAY-ya, spellingy-otoot 'u-mahy“the home of his/her tobacco.” This is only the second case in which residue analysis has shown a Maya vessel to hold the same content as is indicated by a hieroglyphic text on the same vessel.
NEITHER DOPES NOR DUPES: MAYA FARMERS AND IDEOLOGY
Authors: Robin Cynthia 
Published: June 2016

AbstractDrawing inspiration from the work and legacy of Elizabeth Brumfiel, I develop a case study about the lives and religious practices of Maya farmers at the Chan site in Belize, to demonstrate how farmers were neither the dopes, dupes, nor mystified masses of Maya state level ideologies. I use this case study to rethink anthropological theories that attempt to explain the role of state level ideologies in the production of inequality and power, particularly ideas about ideology and false consciousness that are often bundled together and referred to as the ‘dominant ideology thesis.’
THE TRADE IN COOKING POTS UNDER THE AZTEC AND SPANISH EMPIRES
Authors: Rodríguez-Alegría Enrique , Stoner Wesley D. 
Published: June 2016

AbstractElizabeth Brumfiel studied the local production and exchange of pottery in Xaltocan as part of her ongoing efforts to study the link between women's work and political change. We give continuity to Brumfiel's work by presenting a chemical characterization study of Plain Ware and lead-glazed earthenware in Xaltocan, Mexico. These wares were mostly used by women for cooking and storage. The pattern shows that the people of Postclassic Xaltocan increased their reliance on Plain Ware from nearby Cuauhtitlan through time, before and after they were conquered by the Aztecs. After the Spanish conquest, the people of Xaltocan relied more heavily on locally produced Plain Ware and began using lead-glazed earthenware. These two different empires affected the trade in cooking tools even though it was not part of their policies to affect the domestic economy directly.
Caregiving burden and gain among adult-child caregivers caring for parents with dementia in China: the partial mediating role of reciprocal filial piety
Authors: Yu Hua , Wu Li , Chen Shu , Wu Qing , Yang Yuan , Edwards Helen 
Published: June 2016

ABSTRACTBackground:The majority of the family caregivers are adult children in China. The aim of this study was to examine the mediating role of reciprocal filial piety (RFP) between the care recipient's behavioral and psychological symptoms of dementia (BPSD) and the caregiver's burden or gain among adult-child caregivers caring for parents with dementia in China.Methods:Using Kramer's caregiver adaptation model as the research framework, a cross-sectional survey collected data from 401 adult-child caregivers caring for parents with dementia from hospitals in China.Results:Results of the regression analysis revealed that after adjusting for covariates, the regression coefficient between care recipient's BPSD and caregiver burden reduced fromc= 1.01 toc′ = 0.91 when controlling for RFP. Using the bootstrap approach, the estimated indirect effect through RFP between care recipient's BPSD and caregiver burden was 0.11 (95% CI: 0.03, 0.20). The mediation proportion was 11%. The absolute value of the regression coefficient between care recipient's BPSD and caregiver gain reduced fromc= −0.75 toc′ = −0.63 when controlling for RFP. The bootstrapped estimate of the indirect effect through RFP between care recipient's BPSD and caregiver gain was −0.12 (95% CI: −0.18, −0.07). The mediation proportion was 12%.Conclusions:The findings suggest that the effect of care recipient's BPSD on caregiver's burden/gain may be related to the level of RFP among adult-child caregivers in China.

Published: June 2016

AbstractAcute myeloid leukemia (AML) is associated with poor clinical outcome and the development of more effective therapies is urgently needed. G protein-coupled receptors (GPCRs) represent attractive therapeutic targets, accounting for approximately 30% of all targets of marketed drugs. Using next-generation sequencing, we studied the expression of 772 GPCRs in 148 genetically diverse AML specimens, normal blood and bone marrow cell populations as well as cord blood-derived CD34-positive cells. Among these receptors, 30 are overexpressed and 19 are downregulated in AML samples compared with normal CD34-positive cells. Upregulated GPCRs are enriched in chemokine (CCR1, CXCR4, CCR2, CX3CR1, CCR7 and CCRL2), adhesion (CD97, EMR1, EMR2 and GPR114) and purine (including P2RY2 and P2RY13) receptor subfamilies. The downregulated receptors include adhesion GPCRs, such as LPHN1, GPR125, GPR56, CELSR3 and GPR126, protease-activated receptors (F2R and F2RL1) and the Frizzled family receptors SMO and FZD6. Interestingly, specific deregulation was observed in genetically distinct subgroups of AML, thereby identifying different potential therapeutic targets in these frequent AML subgroups.
Torn apart and reunited: impact of a heterotroph on the transcriptome of Prochlorococcus
Authors: Biller Steven J , Coe Allison , Chisholm Sallie W 
Published: June 2016

Abstract
Microbial interactions, whether direct or indirect, profoundly affect the physiology of individual cells and ultimately have the potential to shape the biogeochemistry of the Earth. For example, the growth of Prochlorococcus, the numerically dominant cyanobacterium in the oceans, can be improved by the activity of co-occurring heterotrophs. This effect has been largely attributed to the role of heterotrophs in detoxifying reactive oxygen species that Prochlorococcus, which lacks catalase, cannot. Here, we explore this phenomenon further by examining how the entire transcriptome of Prochlorococcus NATL2A changes in the presence of a naturally co-occurring heterotroph, Alteromonas macleodii MIT1002, with which it was co-cultured for years, separated and then reunited. Significant changes in the Prochlorococcus transcriptome were evident within 6 h of initiating co-culture, with groups of transcripts changing in different temporal waves. Many transcriptional changes persisted throughout the 48 h experiment, suggesting that the presence of the heterotroph affected a stable shift in Prochlorococcus physiology. These initial transcriptome changes largely corresponded to reduced stress conditions for Prochlorococcus, as inferred from the depletion of transcripts encoding DNA repair enzymes and many members of the ‘high light inducible’ family of stress–response proteins. Later, notable changes were seen in transcripts encoding components of the photosynthetic apparatus (particularly, an increase in PSI subunits and chlorophyll synthesis enzymes), ribosomal proteins and biosynthetic enzymes, suggesting that the introduction of the heterotroph may have induced increased production of reduced carbon compounds for export. Changes in secretion-related proteins and transporters also highlight the potential for metabolic exchange between the two strains.

AbstractProduction of chemical fuels by direct solar energy conversion in a photoelectrochemical cell is of great practical interest for developing a sustainable energy system. Various nanoscale designs such as nanowires, nanotubes, heterostructures and nanocomposites have been explored to increase the energy conversion efficiency of photoelectrochemical water splitting. Here we demonstrate a self-organized nanocomposite material concept for enhancing the efficiency of photocarrier separation and electrochemical energy conversion. Mechanically robust photoelectrodes are formed by embedding self-assembled metal nanopillars in a semiconductor thin film, forming tubular Schottky junctions around each pillar. The photocarrier transport efficiency is strongly enhanced in the Schottky space charge regions while the pillars provide an efficient charge extraction path. Ir-doped SrTiO3 with embedded iridium metal nanopillars shows good operational stability in a water oxidation reaction and achieves over 80% utilization of photogenerated carriers under visible light in the 400- to 600-nm wavelength range.
