Published: November 2017

Background:Metabolomics data generation and quantification are different from other types of molecular “omics” data in bioinformatics. Mass spectrometry (MS) based (gas chromatography mass spectrometry (GC-MS), liquid chromatography mass spectrometry (LC-MS), etc.) metabolomics data frequently contain missing values that make some quantitative analysis complex. Typically metabolomics datasets contain 10% to 20% missing values that originate from several reasons, like analytical, computational as well as biological hazard. Imputation of missing values is a very important and interesting issue for further metabolomics data analysis. </P><P> Objective: This paper introduces a new algorithm for missing value imputation in the presence of outliers for metabolomics data analysis. </P><P> Method: Currently, the most well known missing value imputation techniques in metabolomics data are knearest neighbours (kNN), random forest (RF) and zero imputation. However, these techniques are sensitive to outliers. In this paper, we have proposed an outlier robust missing imputation technique by minimizing twoway empirical mean absolute error (MAE) loss function for imputing missing values in metabolomics data.Results:We have investigated the performance of the proposed missing value imputation technique in a comparison of the other traditional imputation techniques using both simulated and real data analysis in the absence and presence of outliers.Conclusion:Results of both simulated and real data analyses show that the proposed outlier robust missing imputation technique is better performer than the traditional missing imputation methods in both absence and presence of outliers.

Authors: Sridharan Kannan , Sivaramakrishnan Gowri 
Published: November 2017

Introduction:
Meibomian Gland Dysfunction (MGD) is a common, often overlooked, chronic condition affecting eyes for which various therapies are being evaluated. Considering the absence of a systematic review and meta-analysis, the present review was carried out.

Methods:
An appropriate search strategy eligibility criteria were framed and electronic databases were scrutinized for appropriate literature. Randomized Controlled Trials (RCTs) enrolling patients diagnosed with MGD were included. Outcome measures were Tear Break Up Time (TBUT), Schirmer’s test, Meibomian Gland (MG) secretion score, MG plugging score, OSDI and SPEED. Cochrane’s tool was used to assess the risk of bias and Forest plot were generated either with fixed or random effects model, with Standardized Mean Difference (SMD).

Results:
TBUTs, Schirmer’s test and OSDI scores for systemic antimicrobials with placebo were 1.58 [1.33, 1.83], 2.93 [0.78, 5.09] and -3.58 [-4.28, -2.89] respectively. No quantitative synthesis was attempted for either mebiomian plugging or meibomian secretion scores and no significant changes were observed with any other outcome parameter.

Conclusion:
Only the systemic antimicrobials were found to improve the clinical features of meibomian gland dysfunction. Varying effects of different therapeutic agents (heat therapies, omega-3-fatty acids and castor oil) were identified for MGD but the risk of bias pertaining to randomization and allocation concealment was found to be associated with most of the current RCTs. More high quality evidence is required to confirm the findings of the present review.

WALKABILITY IN HISTORIC URBAN SPACES: TESTING THE SAFETY AND SECURITY IN MARTYRS' SQUARE IN TRIPOLI
Authors: Abdulla Khairi M. Al-bashir , Abdelmonem Mohamed Gamal , Selim Gehan 
Published: November 2017

Much of the built environment design literature focuses on a composite of walkable spaces variables such as density, diversity, and destination accessibility. One of the most effective factors in walkability is “safety and security”. There is an evident gap in understanding the perceived ability of Libyan public spaces to support walkability. This paper aims to investigate the effectiveness of “walkability” in traditional Libyan urban spaces and analyse the relationship between walking, a safe and secure environment, and its impact on a heritage site in Tripoli city centre. The perceived personal safety of 140 users of the heritage site “Martyrs' Square” were measured; this research is studying the quality of environment and users’ interaction with their environmental issues relating to the study area. Mixed methods were used in this research: this study used both quantitative and qualitative methods to gather information; the quantitative took the form of a questionnaire; and the qualitative took the form of observations. Analysis of quantitative data was conducted with SPSS software; the survey was conducted from August 2016 to September 2016. The results of this study are useful for urban planning, to classify the walkable urban space elements, which could improve the level of walkability in Libyan cities and create sustainable and liveable urban spaces.
SUSTAINED LIVEABILITY: A FRAMEWORK BEYOND ENERGY CONSCIOUS BUILDING CONSERVATION OF MARKET HALLS

Published: November 2017

Market halls are commonly found in contexts of cultural and heritage value. Positioned in urban centres and transport networks, these unique buildings were originally constructed in the 19th century to ensure better food distribution in growing European cities, then copied to other territories such as Egypt. We argue that leaving market halls, with their large spanning structures and indoor open space, for dilapidation is a lost opportunity for sustaining community engagement, and educating the public on the original sustainability, neighbourhood regeneration and cultural thinking that underpinned these buildings. The proposed framework extends current sustainable ‘heritage conservation frameworks’ beyond concepts of adding renewable energy technologies, recycling and sustainable goods movement, to ‘sustaining liveability and social inclusion’. We argue that market halls offer the opportunities to merge the daily activities of buying and selling food with creating local creative economies such as culinary art exhibitions, and culinary schools. The paper consists of two parts: the first discusses the historical urban context of market halls in Cairo; the second proposes a sustainable heritage conservation model for market halls.

Published: November 2017

La empresa familiar adquiere cada vez más importancia en el campo de la investigación organizacional por sus características distintivas que influyen en su desarrollo, su importancia en la generación de empleos y contribución al Producto Interno Bruto Nacional, pero también por los porcentajes tan bajos de supervivencia al transitar de una a otra generación, lo que obliga a observarla desde diferentes ópticas para poder entenderla como fenómeno social. Centrándose la discusión en las diferencias sustanciales que distinguen a las empresas familiares entre sí, se presentan los resultados de una revisión bibliográfica sobre nueve diversas tipologías que han utilizado los estudiosos de la misma para clasificarla. Los resultados indican que durante quince años primó una sola tipología de la empresa familiar: la generacional, posteriormente las clasificaciones se enfocan al estudio de los sistemas que la conforman, la empresa y la familia.

En la actualidad, los quesos crema producidos en las Regiones Costa, Selva y Norte del estado de Chiapas, son los de mayor comercialización. Estos quesos no son producidos en grandes escalas y son heterogéneos. Sin embargo, tienen buena aceptación entre los consumidores por sus características sensoriales que presentan. El propósito de este proyecto fue la caracterización de los quesos étnicos de Chiapas mediante análisis fisicoquímicos para verificar que éstos cumplieran con las normas NMX-F-092-1970 y NOM-243-SSA1-2010. Se llevó a cabo una recolección de muestras de queso crema que se elaboran en las diferentes regiones del Estado de Chiapas, se realizaron pruebas fisicoquímicas: pH, humedad, sólidos totales, grasa, proteína y cenizas, y se compararon con las normas.Los resultados indicaron que, a excepción del pH, los quesos tipo crema de las regiones Costa, Selva y Norte del Estado de Chiapas se encontraban dentro de las Normas Oficiales Mexicanas, y que la Región Costa fue la que presentó los mayores contenidos de cenizas (4.49 %), sin embargo, en relación a contenidos de grasa, sólidos totales, humedad y proteínas en las tres regiones son iguales, por lo que son quesos con valor nutrimental deseable.

AbstractMounting evidence suggests that weight management and physical activity (PA) improve overall health and well being, and reduce the risk of morbidity and mortality among cancer survivors. Although many opportunities exist to include weight management and PA in routine cancer care, several barriers remain. This review summarizes key topics addressed in a recent National Academies of Science, Engineering, and Medicine workshop entitled, “Incorporating Weight Management and Physical Activity Throughout the Cancer Care Continuum.” Discussions related to body weight and PA among cancer survivors included: 1) current knowledge and gaps related to health outcomes; 2) effective intervention approaches; 3) addressing the needs of diverse populations of cancer survivors; 4) opportunities and challenges of workforce, care coordination, and technologies for program implementation; 5) models of care; and 6) program coverage. While more discoveries are still needed for the provision of optimal weight‐management and PA programs for cancer survivors, obesity and inactivity currently jeopardize their overall health and quality of life. Actionable future directions are presented for research; practice and policy changes required to assure the availability of effective, affordable, and feasible weight management; and PA services for all cancer survivors as a part of their routine cancer care.CA Cancer J Clin 2018;68:64‐89. ©2017 American Cancer Society.
Inferring long‐distance dispersal modes in American amphitropically disjunct species through adaptive dispersal structures
Authors: Schenk John J. , Saunders Kelsey 
Published: November 2017

PREMISE OF THE STUDY:A repeated pattern of American amphitropical disjunct species or sister species distributed on either side of the equator has long‐fascinated botanists, but the modes of these disjunctions remain untested. We evaluated diaspore morphology to generate hypotheses on probable dispersal mechanisms.METHODS:The sizes and structures of diaspores, habit, habitat, distribution, and dispersal units were collected for 108 species from literature searches and herbarium specimens. Variation was evaluated with summary statistics, χ2 tests with Monte Carlo simulations, ANOVAs, and the nonparametric Mann–Whitney test.KEY RESULTS:Seeds were the dispersing diaspore in 38.0% of the species, 45.4 were dispersed as fruits, and the remaining were dispersed as infructescences or spores. Diaspores were epizoochorous (52.8%), anemochorous (20.4%), achorous (15.7%), endozoochorous (8.3%), and hydrochorous (2.8%). Epizoochory was significantly greater than expected. Zoochory occurred more frequently than expected when considering achorous diaspores as animal‐dispersed. Most species were associated with wetland, woodland, and grassland habitats. An ANOVA revealed that diaspores associated with hydrochory were larger and anemochory was smaller; all other syndromes were not significantly different.CONCLUSIONS:Botanists have long‐held the assumption that bird migrations are responsible for amphitropical disjunctions. Our results support this hypothesis, with the majority of these events occurring by external attachment of small fruits. However, our results also indicate that anemochory might play a greater role in producing amphitropical distributions than previously thought and at a greater rate than endozoochory or hydrochory.

Abstract
We describe a joint high-contrast imaging survey for planets at the Keck and Very Large Telescope of the last large sample of debris disks identified by the Spitzer Space Telescope. No new substellar companions were discovered in our survey of 30 Spitzer-selected targets. We combine our observations with data from four published surveys to place constraints on the frequency of planets around 130 debris disk single stars, the largest sample to date. For a control sample, we assembled contrast curves from several published surveys targeting 277 stars that do not show infrared excesses. We assumed a double power-law distribution in mass and semimajor axis (SMA) of the form

, where we adopted power-law values and logarithmically flat values for the mass and SMA of planets. We find that the frequency of giant planets with masses 5–20 M
Jup and separations 10–1000 au around stars with debris disks is 6.27% (68% confidence interval 3.68%–9.76%), compared to 0.73% (68% confidence interval 0.20%–1.80%) for the control sample of stars without disks. These distributions differ at the 88% confidence level, tentatively suggesting distinctness of these samples.
Galaxy Populations in Massive z = 0.2–0.9 Clusters. I. Analysis of Spectroscopy

Published: November 2017

Abstract
We present an analysis of stellar populations in passive galaxies in seven massive X-ray clusters at z = 0.19–0.89. Based on absorption-line strengths measured from our high signal-to-noise spectra, the data support primarily passive evolution of the galaxies. We use the scaling relations between velocity dispersions and the absorption-line strengths to determine representative mean line strengths for the clusters. From the age determinations based on the line strengths (and stellar population models), we find a formation redshift of

. Based on line strength measurements from high signal-to-noise composite spectra of our data, we establish the relations between velocity dispersions, ages, metallicities [M/H], and abundance ratios [α/Fe] as a function of redshift. The [M/H]–velocity dispersion and [α/Fe]–velocity dispersion relations are steep and tight. The age–velocity dispersion relation is flat, with zero-point changes reflecting passive evolution. The scatter in all three parameters is within 0.08–0.15 dex at fixed velocity dispersions, indicating a large degree of synchronization in the evolution of the galaxies. We find an indication of cluster-to-cluster differences in metallicities and abundance ratios. However, variations in stellar populations with the cluster environment can only account for a very small fraction of the intrinsic scatter in the scaling relations. Thus, within these very massive clusters, the main driver of the properties of the stellar populations in passive galaxies appears to be the galaxy velocity dispersion.
New Identifications of the CCH Radical in Planetary Nebulae: A Connection to C60?
Authors: Schmidt D. R. , Ziurys L. M. 
Published: November 2017

Abstract
New detections of CCH have been made toward nine planetary nebulae (PNe), including K4–47, K3–58, K3–17, M3–28, and M4–14. Measurements of the N = 1 → 0 and N = 3 → 2 transitions of this radical near 87 and 262 GHz were carried out using the new 12 m and the Sub-Millimeter Telescope (SMT) of the Arizona Radio Observatory (ARO). The presence of fine and/or hyperfine structure in the spectra aided in the identification. CCH was not observed in two PNe which are sources of C60. The planetary nebulae with positive detections represent a wide range of ages and morphologies, and all had previously been observed in HCN and HNC. Column densities for CCH in the PNe, determined from radiative transfer modeling, were N
tot(CCH) ∼ 0.2–3.3 × 1015 cm−2, corresponding to fractional abundances with respect to H2 of f ∼ 0.2–47 × 10−7. The abundance of CCH was found to not vary significantly with kinematic age across a time span of ∼10,000 years, in contrast to predictions of chemical models. CCH appears to be a fairly common constituent of PNe that are carbon-rich, and its distribution may anti-correlate with that of C60. These results suggest that CCH may be a product of C60 photodestruction, which is known to create C2 units. The molecule may subsequently survive the PN stage and populate diffuse clouds. The distinct, double-horned line profiles for CCH observed in K3–45 and M3–28 indicate the possible presence of a bipolar flow oriented at least partially toward the line of sight.
Electron-impact Multiple-ionization Cross Sections for Atoms and Ions of Helium through Zinc
Authors: Hahn M. , Müller A. , Savin D. W. 
Published: November 2017

Abstract
We compiled a set of electron-impact multiple-ionization (EIMI) cross section for astrophysically relevant ions. EIMIs can have a significant effect on the ionization balance of non-equilibrium plasmas. For example, it can be important if there is a rapid change in the electron temperature or if there is a non-thermal electron energy distribution, such as a kappa distribution. Cross section for EIMI are needed in order to account for these processes in plasma modeling and for spectroscopic interpretation. Here, we describe our comparison of proposed semiempirical formulae to available experimental EIMI cross-section data. Based on this comparison, we interpolated and extrapolated fitting parameters to systems that have not yet been measured. A tabulation of the fit parameters is provided for 3466 EIMI cross sections and the associated Maxwellian plasma rate coefficients. We also highlight some outstanding issues that remain to be resolved.
