A coordinated multi‐point‐based quality of service provision resource allocation scheme with inter‐cell interference mitigation
Authors: Gong Ming , Ho Pin‐Han , Lin Chih‐Hao
Published: November 2014

The paper investigates resource allocation via power control for inter‐cell interference (ICI) mitigation in an orthogonal frequency division multiple access‐based cellular network. The proposed scheme is featured by a novel subcarrier assignment mechanism at a central controller for ICI, which is further incorporated with an intelligent power control scheme. We formulate the system optimization task into a constrained optimization problem for maximizing accepted users' requirements. To improve the computation efficiency, a fast yet effective heuristic approach is introduced for divide and conquer. Simulation results demonstrate that the proposed resource allocation scheme can significantly improve the network capacity compared with a common approach by frequency reuse.

Cardiac catheterization: consequences for the endothelium and potential for nanomedicine
Authors: Sobolewski Peter , El Fray Miroslawa
Published: November 2014

Cardiac catheterization results in interactions between the catheter and surfaces and the artery lumen, which is lined by the endothelium. These interactions can range from minor rubbing to severe mechanical injury. Further, in the case of radial access, even atraumatic interactions have consequences ranging from clinical complications, such as radial spasm and radial occlusion, to lasting endothelial cell dysfunction. These consequences may be underappreciated; however, endothelial cells play a central role in maintaining vascular homeostasis via nitric oxide production. Existing treatment paradigms do not address endothelial dysfunction or damage and, thus, novel therapeutic approaches are needed. Nanomedicine, in particular, offers great potential in the form of targeted drug delivery, via functionalized coatings or nanocarriers, aimed at increased nitric oxide bioavailability or reduced inflammation.

Inside single cells: quantitative analysis with advanced optics and nanomaterials
Authors: Cui Yi , Irudayaraj Joseph
Published: November 2014

Single‐cell explorations offer a unique window to inspect molecules and events relevant to mechanisms and heterogeneity constituting the central dogma of biology. A large number of nucleic acids, proteins, metabolites, and small molecules are involved in determining and fine‐tuning the state and function of a single cell at a given time point. Advanced optical platforms and nanotools provide tremendous opportunities to probe intracellular components with single‐molecule accuracy, as well as promising tools to adjust single‐cell activity. To obtain quantitative information (e.g., molecular quantity, kinetics, and stoichiometry) within an intact cell, achieving the observation with comparable spatiotemporal resolution is a challenge. For single‐cell studies, both the method of detection and the biocompatibility are critical factors as they determine the feasibility, especially when considering live‐cell analysis. Although a considerable proportion of single‐cell methodologies depend on specialized expertise and expensive instruments, it is our expectation that the information content and implication will outweigh the costs given the impact on life science enabled by single‐cell analysis.

Effects of the Dietary Approach to Stop Hypertension (DASH) diet on cardiovascular risk factors: a systematic review and meta-analysis
Authors: Siervo Mario , Lara Jose , Chowdhury Shakir , Ashor Ammar , Oggioni Clio , Mathers John C.
Published: November 2014

The Dietary Approach to Stop Hypertension (DASH) is recommended to lower blood pressure (BP), but its effects on cardiometabolic biomarkers are unclear. A systematic review and meta-analysis of randomised controlled trials (RCT) was conducted to determine the effects of the DASH diet on cardiovascular risk factors. Medline, Embase and Scopus databases were searched from inception to December 2013. Inclusion criteria were as follows: (1) DASH diet; (2) RCT; (3) risk factors including systolic and diastolic BP and glucose, HDL, LDL, TAG and total cholesterol concentrations; (4) control group. Random-effects models were used to determine the pooled effect sizes. Meta-regression analyses were carried out to examine the association between effect sizes, baseline values of the risk factors, BMI, age, quality of trials, salt intake and study duration. A total of twenty articles reporting data for 1917 participants were included in the meta-analysis. The duration of interventions ranged from 2 to 24 weeks. The DASH diet was found to result in significant decreases in systolic BP ( − 5·2 mmHg, 95 % CI − 7·0, − 3·4; P< 0·001) and diastolic BP ( − 2·6 mmHg, 95 % CI − 3·5, − 1·7; P< 0·001) and in the concentrations of total cholesterol ( − 0·20 mmol/l, 95 % CI − 0·31, − 0·10; P< 0·001) and LDL ( − 0·10 mmol/l, 95 % CI − 0·20, − 0·01; P= 0·03). Changes in both systolic and diastolic BP were greater in participants with higher baseline BP or BMI. These changes predicted a reduction of approximately 13 % in the 10-year Framingham risk score for CVD. The DASH diet improved cardiovascular risk factors and appeared to have greater beneficial effects in subjects with an increased cardiometabolic risk. The DASH diet is an effective nutritional strategy to prevent CVD.

EFFECTS OF Ca AND P NUTRIENT LEVELS ON THE GROWTH OF N-FERTILIZED AND RHIZOBIUM-NODULATED PHASEOLUS VULGARIS L. SUBJECTED TO TWO CONTRASTING TROPICAL SOLAR RADIATION REGIMES AND SPRAYED WITH PROPYL GALLATE
Authors: IZAGUIRRE-MAYORAL MARÍA LUISA , SILVERA JULIAN , RODRÍGUEZ MÓNICA
Published: November 2014

Interactions between two contrasting photosynthetic photon flux densities (PPFD) and increasing Ca and P concentrations were analysed in N-fertilised (+N) and Rhizobium-inoculated (+Rh) Phaseolus vulgaris plants grown for 30 days in glasshouses. Plants were grown in sand-filled Leonard jars with 0.9 L N-free for +Rh plants or plus 6 mM KNO3 for +N plants nutrient solution, pH 6.2 in the lower compartment, and were subjected to midday PPFD ≥ 1650 ≤ 1800 mmol m−2 s−1/37±2°C air temperature (HI/HT) or PPDF ≥ 900 ≤ 1200 μmol m−2 s−1/26±2°C air temperature (MI/MT). The nutrient solutions were supplied with 1, 2, 3 or 4 mM P in combination with 1 or 4 mM Ca. Results revealed a 100% mortality of the HI/HT+Rh plants at the juvenile stage of growth. Whereas, all HI/HT+N plants reached the preflowering stage but showed smaller shoot masses, lower chlorophyll concentrations, unusually high chlorophyll a/b ratios and higher shoot nitrate concentrations when compared to values in +N plants grown at MI/MT. Increasing concentrations of P and Ca, or the daily spray of leaves with 2 mM propyl gallate (Pg), did not counteract the negative effects of HI/HT on +Rh and +N plants. Maximum growth, nodulation, chlorophyll concentration and catabolism of ureides in leaves were exclusively observed in +Rh plants grown under MI/MT conditions and supplied with 2 mM P and 1 mM Ca. In contrast, the greater growth of +N plants, associated with higher chlorophyll and nitrate concentrations, took place at MI/MT conditions combined with 1 mM P and 4 mM Ca. Pg further enhanced the growth of MI/MT+Rh and MI/MT+N plants grown at P < 2 mM, at 1 or 4 mM Ca, respectively. At MI/MT, there was a positive relationship between leaf carotenoid concentration and growth of +Rh and +N plants.
Confessing Incest to a Rabbi: A Talmudic Story in Its Zoroastrian Context
Authors: Kiel Yishai
Published: November 2014

A fascinating anecdote preserved in the Babylonian Talmud (b. ῾Abod. Zar. 17a) tells the story of a woman who comes before Rav Hisda and discloses to him that her younger son is the product of incestuous intercourse she has performed with her older son. Rav Hisda, in turn, rather than instructing her with regard to her penance, orders the preparation of her shrouds, thus indicating that her death is inescapable and imminent. Although the nature of the encounter between Rav Hisda and the sinner is not explicit in the story itself, the passage is situated within the Babylonian Talmud in the context of a broader legal and theological discussion centered on the penitential requirements for a person seeking to turn away fromminut(heresy).
The Exceptionalist Optics of 9/11 Photography
Authors: DARDA JOSEPH
Published: November 2014

During and after the 2001 attacks on New York City and Washington, thousands of photographs were taken. None, however, would become as iconic as Thomas Franklin's photo of three firefighters raising an American flag above the rubble of the World Trade Center. Franklin's photo, I argue in this essay, casts 9/11 in the familiar myth of American exceptionalism, screening out but still gesturing to the heterogeneous memories left unsettled and animate in amateur photographs, missing-person posters, bodies in pain, and performance. In considering the struggle over the visual memory of the attacks, I first consider how, in the wake of 9/11, the discourse of exceptionalism served to disavow the exceptions historically taken by the state and to rationalize the War on Terror. I show how this system of myths works in dialectical relation to other disruptive forms of cultural memory. I then read Franklin's iconic photograph as a screen by which traumatic memories are masked and onto which nationalist desires are projected. Finally, I analyze 9/11 photography that troubles the exceptionalist optics of Franklin's photo by evoking the visual legacy of the Vietnam War and so challenging the logic of righteous warfare.
Sensitizing effect of early adversity on depressive reactions to later proximal stress: Moderation by polymorphisms in serotonin transporter and corticotropin releasing hormone receptor genes in a 20-year longitudinal study
Authors: Starr Lisa R. , Hammen Constance , Conway Christopher C. , Raposa Elizabeth , Brennan Patricia A.
Published: November 2014

Previous research supports gene–environment interactions for polymorphisms in the corticotropin hormone receptor 1 gene (CRHR1) and the serotonin transporter gene linked polymorphic region (5-HTTLPR) in predicting depression, but it has rarely considered genetic influences on stress sensitization processes, whereby early adversities (EA) increase depressive reactivity to proximal stressors later in life. The current study tested a gene–environment–environment interaction (G × E × E; specifically, gene–EA–proximal stress interaction) model of depression in a 20-year longitudinal study. Participants were assessed prospectively for EA up to age 5 and recent chronic stress and depressive symptoms at age 20 and genotyped forCRHR1single nucleotide polymorphismrs110402and5-HTTLPR. EA predicted stronger associations between recent chronic stress and depression, and the effect was moderated by genes.CRHR1A alleles and5-HTTLPRshort alleles were associated with greater stress sensitization (i.e., greater depressive reactivity to chronic stress for those also exposed to high levels of EA). The results are consistent with the notion that EA exposure results in neurobiological and cognitive–emotional consequences (e.g., altered hypothalamic–pituitary–adrenal axis functioning), leading to emotional distress in the face of recent stressors among those with certain genetic characteristics, although further research is needed to explore explanatory mechanisms.
Atypical patterns of respiratory sinus arrhythmia index an endophenotype for depression
Authors: Yaroslavsky Ilya , Rottenberg Jonathan , Kovacs Maria
Published: November 2014

Can atypical patterns of parasympathetic nervous system activity serve as endophenotypes for depression? Using respiratory sinus arrhythmia (RSA) as an index of parasympathetic nervous system function, we examined this question in two studies: one involving mothers with and without depression histories and their offspring (at high and low risk for depression, respectively), and a further study of adolescent sibling pairs concordant and discordant for major depression. In both studies, subjects were exposed to sad mood induction; subjects' RSA was monitored during rest periods and in response to the mood induction. We used Gottesman and Gould's (2003) criteria for an endophenotype and a priori defined “atypical” and “normative” RSA patterns (combinations of resting RSA and RSA reactivity). We found that atypical RSA patterns (a) predicted current depressive episodes and remission status among women with histories of juvenile onset depression and healthy controls, (b) predicted longitudinal trajectories of depressive symptoms among high- and low-risk young offspring, (c) were concordant across mothers and their juvenile offspring, (d) were more prevalent among never-depressed youth at high risk for depression than their low-risk peers, and (e) were more concordant across adolescent sibling pairs in which both versus only one had a history of major depression. Thus, the results support atypical RSA patterns as an endophenotype for depression. Possible mechanisms by which RSA patterns increase depression risk and their genetic contributors are discussed.
Urban conflict and legal strategy in medieval England: the case of Bishop's Lynn, 1346–1350
Authors: PHILLIPS MATTHEW
Published: November 2014

Urban conflict in medieval England often took one of two forms: public confrontation involving ritualistic acts of transgression on the one hand and legal challenges involving litigation on the other. This article explores an urban dispute in the latter category fought at Bishop's Lynn between 1346 and 1350. The rich series of records surviving from this dispute provides a rare opportunity to reconstruct in detail the legal strategies adopted throughout the conflict. The case is significant for the innovative legal challenge adopted by the burgesses, and for the subsequent campaign of misinformation propagated in parliament by the bishop of Norwich.
Public support for a sugar-sweetened beverage tax and pro-tax messages in a Mid-Atlantic US state
Authors: Donaldson Elisabeth A , Cohen Joanna E , Rutkow Lainie , Villanti Andrea C , Kanarek Norma F , Barry Colleen L
Published: November 2014

Objective

To examine the characteristics of supporters and opponents of a sugar-sweetened beverage (SSB) tax and to identify pro-tax messages that resonate with the public.

Design

A survey was administered by telephone in February 2013 to assess public opinion about a penny-per-ounce tax on SSB. Support was also examined for SSB consumption reduction and pro-tax messages. Individual characteristics including sociodemographics, political affiliation, SSB consumption behaviours and beliefs were explored as predictors of support using logistic regression.

Setting

A representative sample of voters was recruited from a Mid-Atlantic US state.

Subjects

The sample included 1000 registered voters.

Results

Findings indicate considerable support (50 %) for an SSB tax. Support was stronger among Democrats, those who believe SSB are a major cause of childhood obesity and those who believe childhood obesity warrants a societal intervention. Belief that a tax would be effective in lowering obesity rates was associated with support for the tax and pro-tax messages. Respondents reporting that a health-care provider had recommended they lose weight were less convinced by pro-tax messages. Women, Independents and those concerned about childhood obesity were more convinced by the SSB reduction messages. Overall, the most popular messages focused on the importance of reducing consumption among children without mentioning the tax.

Conclusions

Understanding who supports and opposes SSB tax measures can assist advocates in developing strategies to maximize support for this type of intervention. Messages that focus on the effect of consumption on children may be useful in framing the discussion around SSB tax proposals.
Surface flux patterns on planets in circumbinary systems and potential for photosynthesis
Authors: Forgan Duncan H. , Mead Alexander , Cockell Charles S. , Raven John A.
Published: November 2014

Recently, the Kepler Space Telescope has detected several planets in orbit around a close binary star system. These so-called circumbinary planets will experience non-trivial spatial and temporal distributions of radiative flux on their surfaces, with features not seen in their single-star orbiting counterparts. Earth-like circumbinary planets inhabited by photosynthetic organisms will be forced to adapt to these unusual flux patterns. We map the flux received by putative Earth-like planets (as a function of surface latitude/longitude and time) orbiting the binary star systems Kepler-16 and Kepler-47, two star systems which already boast circumbinary exoplanet detections. The longitudinal and latitudinal distribution of flux is sensitive to the centre-of-mass motion of the binary, and the relative orbital phases of the binary and planet. Total eclipses of the secondary by the primary, as well as partial eclipses of the primary by the secondary add an extra forcing term to the system. We also find that the patterns of darkness on the surface are equally unique. Beyond the planet's polar circles, the surface spends a significantly longer time in darkness than latitudes around the equator, due to the stars’ motions delaying the first sunrise of spring (or hastening the last sunset of autumn). In the case of Kepler-47, we also find a weak longitudinal dependence for darkness, but this effect tends to average out if considered over many orbits. In the light of these flux and darkness patterns, we consider and discuss the prospects and challenges for photosynthetic organisms, using terrestrial analogues as a guide.
First results of the ORGANIC experiment on EXPOSE-R on the ISS

Published: November 2014

The ORGANIC experiment on EXPOSE-R spent 682 days outside the International Space Station, providing continuous exposure to the cosmic-, solar- and trapped-particle radiation background for fourteen samples: 11 polycyclic aromatic hydrocarbons (PAHs) and three fullerenes. The thin films of the ORGANIC experiment received, during space exposure, an irradiation dose of the order of 14 000 MJ m−2 over 2900 h of unshadowed solar illumination. Extensive analyses were performed on the returned samples and the results compared to ground control measurements. Analytical studies of the returned samples included spectral measurements from the vacuum ultraviolet to the infrared range and time-of-flight secondary ion mass spectrometry. Limited spectral changes were observed in most cases pointing to the stability of PAHs and fullerenes under space exposure conditions. Furthermore, the results of these experiments confirm the known trend in the stability of PAH species according to molecular structure: compact PAHs are more stable than non-compact PAHs, which are themselves more stable than PAHs containing heteroatoms, the last category being the most prone to degradation in the space environment. We estimate a depletion rate of the order of 85 ± 5% over the 17 equivalent weeks of continuous unshadowed solar exposure in the most extreme case tetracene (smallest, non-compact PAH sample). The insignificant spectral changes (below 10%) measured for solid films of large or compact PAHs and fullerenes indicate a high stability under the range of space exposure conditions investigated on EXPOSE-R.
PROVINCIALIZING AMERICA: NEW AND NOT SO NEW INTELLECTUAL HISTORIES OF WEIMAR GERMANY
Authors: GRAF RÜDIGER
Published: November 2014

Together the two volumes under review contain over forty essays on the intellectual history of Weimar Germany and its legacy today. The wide interdisciplinary field of authors, historians, philosophers, theologians, and literary, legal, and religious scholars, as well as social and political scientists, testifies to the continuing fascination of this era of thought in Anglo-American academia. With the exceptions of Mitchell G. Ash, Michael Krois, and Klaus Tanner, the authors teach at American, British or Canadian universities and represent major tendencies of the anglophone engagement with Weimar's intellectual history. Despite the fact that intellectual history of the Weimar Republic has been a flourishing field of research in Germany over the last decades, the volumes contain no contributions by German historians. This observation is by no means negligible in an age of transnational academic exchange, as may be exemplified by the recentOxford Handbook of Modern German History, which contains contributions by German, American, and British experts in their fields.
Electron relaxation in the CdSe quantum dot - ZnO composite: prospects for photovoltaic applications
Authors: Žídek Karel , Abdellah Mohamed , Zheng Kaibo , Pullerits Tõnu
Published: November 2014

Quantum dot (QD)-metal oxide composite forms a “heart” of the QD-sensitized solar cells. It maintains light absorption and electron-hole separation in the system and has been therefore extensively studied. The interest is largely driven by a vision of harvesting the hot carrier energy before it is lost via relaxation. Despite of importance of the process, very little is known about the carrier relaxation in the QD-metal oxide composites. In order to fill this gap of knowledge we carry out a systematic study of initial electron dynamics in different CdSe QD systems. Our data reveal that QD attachment to ZnO induces a speeding-up of transient absorption onset. Detailed analysis of the onset proves that the changes are caused by an additional relaxation channel dependent on the identity of the QD-ZnO linker molecule. The faster relaxation represents an important factor for hot carrier energy harvesting, whose efficiency can be influenced by almost 50%.

Published: November 2014

Analytical detection methods based on lab-on-a-chip (LoC) technologies have been on the rise in the last decade as they provide numerous advantages in comparison with their larger-scale counterparts, like low sample volume requirements, high-throughput capability and better performance. LoC system's designs and development are simultaneously dependent upon the physicochemical properties of the analyte under consideration and governed by the fundamental laws of fluid dynamics, that are usually applied at the macroscale. This chapter provides a brief overview of fluid hydrodynamics and also transport phenomena at the microscale that are relevant to analyte-detection science. This chapter will provide a solid grounding in the possibilities and limitations inherent to operating at the small scale.

Word Recognition and Nonword Repetition in Children With Language Disorders: The Effects of Neighborhood Density, Lexical Frequency, and Phonotactic Probability
Authors: Rispens Judith , Baker Anne , Duinmeijer Iris
Published: November 2014

Purpose

The effects of neighborhood density (ND) and lexical frequency on word recognition and the effects of phonotactic probability (PP) on nonword repetition (NWR) were examined to gain insight into processing at the lexical and sublexical levels in typically developing (TD) children and children with developmental language problems.

Method

Tasks measuring NWR and word recognition were administered to 5 groups of children: 2 groups of TD children (5 and 8 years old), children with specific language impairment (SLI), children with reading impairment (RI), and children with SLI + RI (all 7–8 years old).

Results

High ND had a negative effect on word recognition in the older TD children and in the children with RI only. There was no ND effect in the younger children or in the children with SLI, who all had lower receptive vocabulary scores than the age-matched TD children and the RI groups. For all groups, NWR items with low PP were more difficult to repeat than items with high PP. This effect was especially pronounced in children with RI.

Conclusion

Both the stage of vocabulary development and the type of language impairment (SLI or RI) impact the way ND and PP affect word recognition and NWR.

Estimation of clutter rank of wideband airborne MIMO radar
Authors: Li Ruiyang , Li Jun , Luo Cheng , Han Chunlin , Li Huiyong
Published: November 2014

A convenient formula for the estimation of clutter degrees of freedom is derived in wideband multiple‐input and multiple‐output (MIMO) radar with frequency diversity waveforms. The estimation of the clutter rank of MIMO radar is extended to the mode of the wideband with the help of the time‐bandwidth product lemma; this could be valuable for designing an optimal technique in the application of parameter estimation, target recognition etc. The proposed rule is well verified by simulation results.
