High sugar content of baby foods sold in Europe
Authors: Hutchinson Jayne , Rippin Holly , Threapleton Diane , Jewell Jo , Breda Joao , Cade Janet 
Published: June 2020

AbstractWHO guidelines on sugars strongly recommend reducing free sugar intake to below 10% of total energy, also their guidance on ‘Ending the inappropriate promotion of foods for infants and young children (IYC)’ recommends avoiding free sugars. Information on the sugar content of commercially available complementary foods (CACFs) for infants is limited, and the levels of added, free, and total sugar in baby foods is not fully addressed in existing guidelines. Up-to-date data is needed to inform recommendations for revising European regulations and guidelines. Front and back of pack information for baby foods from countries across the WHO European Region was collected. Mean sugar content per 100 g product and percentage energy from total sugar by food category were determined. The percentage of products containing added sugars by food category was calculated; as was the percentage of savoury meals containing pureed fruit, which is often used to sweeten products. The creation of the product categories was part of WHO work to develop a Nutrient Profile Model for CACFs marketed as suitable for IYC aged 6–36 months. A literature review of current issues also informed the process. 2642 CACFs from 10 countries were summarised; 768 products sold in the UK; over 200 each from Denmark (319), Spain (241), Italy (430) and Malta (243) and between 100–200 from Hungry, Norway, Portugal and Slovenia. About a third of energy in CACFs in these European countries came from total sugar and the mean contribution of total sugar for most food categories in the countries was higher than 10%. The amount of added and free sugar content was not labelled. However, added sugars listed as ingredients were widespread across product categories, and the type varied across countries and products, though concentrated fruit juice was most common. Savoury meal purees did not contain added sugars except in UK and Malta; however fruit puree as an ingredient was found in 7% of those examined across Europe and were most likely in UK savoury meals: in 15% on average and 41% of pureed meals with meat as the first named food. In conclusion, the sugar content of baby foods across Europe is high and updated regulations and reformulation are needed. Sugars can be restricted in a variety of ways, but first consultation with WHO Europe Member States is required to support the establishment of effective legal and policy measures to avoid inappropriate manufacture and selling of infant foods.

AbstractToxoplasmosis is a parasitic zoonotic disease caused by Toxoplasma (T.) gondii. Limited data are available on the occurrence of T. gondii in women especially pregnant women in Pakistan. The present study aimed to determine the occurrence and risk factors associated with T. gondii in pregnant and non-pregnant women in Punjab Province, Pakistan. A cross-sectional study was conducted and 593 samples were collected from pregnant (n = 293) and non-pregnant (n = 300) women of District Headquarter Hospitals of Chiniot, Faisalabad, Jhang and Okara, Pakistan. Data related to demographic parameters and risk factors were collected using a pretested questionnaire on blood sampling day. Serum samples were screened for antibodies (IgG) against T. gondii using ELISA. A univariant and binomial logistic regression was applied to estimate the association between seropositive and explanatory variables considering the 95% confidence interval. P value ⩽0.05 was considered statistically significant for all analysis. Out of 593, 44 (7.42%) women were seropositive for T. gondii IgG antibodies. Occupation, age, sampling location, socioeconomic status, contact with cat, pregnancy status and trimester of pregnancy were significantly associated with seropositivity for T. gondii antibodies. Location and trimester of pregnancy were identified as potential risk factors for T. gondii seropositivity based on binomial logistic regression. Toxoplasma gondii is prevalent in pregnant and non-pregnant women. Therefore, now a necessitated awareness is required to instruct the individuals about these infectious diseases (toxoplasmosis) and their control strategies to maintain the health of human population. Moreover, health awareness among public can help the minimization of T. gondii infection during pregnancy and subsequent risk of congenital toxoplasmosis.
HUMAN STRAINS: JAMES CLARKE AND THE MUTATING MUSICAL IDEA
Authors: Whittall Arnold 
Published: June 2020

AbstractJames Clarke, successfully completing a PhD in composition as he turned 60, has never been afraid of challenging convention. A recent piece for unaccompanied violin, 2017-V, takes a typically abrasive look at a long-established instrumental genre, and relishes the obvious restrictions – four strings, two hands – in a forceful exploration of a single, multivalent musical idea. That idea evolves through febrile transformations to promote a connected yet never entirely stable music discourse. Various appropriate contexts are referenced in order to define and underline the music's distinctiveness.
The Logic of Illicit Flows in Armed Conflict
Authors: Idler Annette 
Published: June 2020

ABSTRACTWhy is there variation in how violent nonstate groups interact in armed conflict? Where armed conflict and organized crime converge in unstable regions worldwide, these groups sometimes enter cooperative arrangements with opposing groups. Within the same unstable setting, violent nonstate groups forge stable, long-term relations with each other in some regions, engage in unstable, short-term arrangements in others, and dispute each other elsewhere. Even though such paradoxical arrangements have intensified and perpetuated war, extant theories on group interactions that focus on territory and motivations overlook their concurrent character. Challenging the literature that focuses on conflict dynamics alone, the author argues that the spatial distribution of illicit flows influences how these interactions vary. By mapping cocaine supply chain networks, the author shows that long-term arrangements prevail at production sites, whereas short-term arrangements cluster at trafficking nodes. The article demonstrates through process tracing how the logic of illicit flows produces variation in the groups’ cooperative arrangements. This multiyear, multisited study includes over six hundred interviews in and about Colombia’s remote, war-torn borderlands.

Abstract

Background
The median duration of hospital stays due to COVID-19 has been reported in several studies on China as 10−13 days. Global studies have indicated that the length of hospitalisation depends on different factors, such as the time elapsed from exposure to symptom onset, and from symptom onset to hospital admission, as well as specificities of the country under study. The goal of this paper is to identify factors associated with the median duration of hospital stays of COVID-19 patients during the second COVID-19 wave that hit Vietnam from 5 March to 8 April 2020.

Method
We used retrospective data on 133 hospitalised patients with COVID-19 recorded over at least two weeks during the study period. The Cox proportional-hazards regression model was applied to determine the potential risk factors associated with length of hospital stay.

Results
There were 65 (48.9%) females, 98 (73.7%) patients 48 years old or younger, 15 (11.3%) persons with comorbidities, 21 (16.0%) severely ill patients and 5 (3.8%) individuals with life-threatening conditions. Eighty-two (61.7%) patients were discharged after testing negative for the SARS-CoV-2 virus, 51 were still in the hospital at the end of the study period and none died. The median duration of stay in a hospital was 21 (IQR: 16–34) days. The multivariable Cox regression model showed that age, residence and sources of contamination were significantly associated with longer duration of hospitalisation.

Conclusion
A close look at how long COVID-19 patients stayed in the hospital could provide an overview of their treatment process in Vietnam, and support the country's National Steering Committee on COVID-19 Prevention and Control in the efficient allocation of resources over the next stages of the COVID-19 prevention period.
Encodings of Turing machines in linear logic
Authors: Clift James , Murfet Daniel 
Published: June 2020

AbstractThe Sweedler semantics of intuitionistic differential linear logic takes values in the category of vector spaces, using the cofree cocommutative coalgebra to interpret the exponential and primitive elements to interpret the differential structure. In this paper, we explicitly compute the denotations under this semantics of an interesting class of proofs in linear logic, introduced by Girard: the encodings of step functions of Turing machines. Along the way we prove some useful technical results about linear independence of denotations of Church numerals and binary integers.
A clustering framework for lexical normalization of Roman Urdu

Published: June 2020

AbstractRoman Urdu is an informal form of the Urdu language written in Roman script, which is widely used in South Asia for online textual content. It lacks standard spelling and hence poses several normalization challenges during automatic language processing. In this article, we present a feature-based clustering framework for the lexical normalization of Roman Urdu corpora, which includes a phonetic algorithm UrduPhone, a string matching component, a feature-based similarity function, and a clustering algorithm Lex-Var. UrduPhone encodes Roman Urdu strings to their pronunciation-based representations. The string matching component handles character-level variations that occur when writing Urdu using Roman script. The similarity function incorporates various phonetic-based, string-based, and contextual features of words. The Lex-Var algorithm is a variant of the k-medoids clustering algorithm that groups lexical variations of words. It contains a similarity threshold to balance the number of clusters and their maximum similarity. The framework allows feature learning and optimization in addition to the use of predefined features and weights. We evaluate our framework extensively on four real-world datasets and show an F-measure gain of up to 15% from baseline methods. We also demonstrate the superiority of UrduPhone and Lex-Var in comparison to respective alternate algorithms in our clustering framework for the lexical normalization of Roman Urdu.

Published: June 2020

AbstractTo improve speech emotion recognition, a U-acoustic words emotion dictionary (AWED) features model is proposed based on an AWED. The method models emotional information from acoustic words level in different emotion classes. The top-list words in each emotion are selected to generate the AWED vector. Then, the U-AWED model is constructed by combining utterance-level acoustic features with the AWED features. Support vector machine and convolutional neural network are employed as the classifiers in our experiment. The results show that our proposed method in four tasks of emotion classification all provides significant improvement in unweighted average recall.

Published: June 2020

AbstractMungbean yellow mosaic virus (MYMV) disease is one of the most devastating biotic constraints of mungbean production in India. Dependable knowledge on the number and mode of action of genes controlling resistance to MYMV disease is one of the keys to develop resistant cultivars. The F1s of four crosses derived from four MYMV resistant genotypes × one highly susceptible genotype, their parents, F2s and F3s along with a susceptible check were screened for responses to MYMV disease following the infector-row technique under natural infection conditions. A good fit of F2 population segregation to the hypothesized ratio of 15 susceptible:1 resistant and that of F3 population segregation to the expected ratio of 55 susceptible:9 resistant at 55 days after planting confirmed the involvement of two recessive genes in imparting resistance to MYMV disease.
Caught in the web: A tale of filament galaxies
Authors: Singh Ankit , Mahajan Smriti , Shobhana Devika 
Published: June 2020

AbstractThe Coma supercluster is one of the largest, nearby (∼100h−1Mpc) gravitationally bound structures known in the universe. It comprises two large clusters of galaxies and several galaxy groups intersected by a complex network of filaments, providing the perfect laboratory for studying the evolution of galaxies in a range of ‘continuous’ environments. We characterised the different components of the environment to study the properties of galaxies in the optical and ultraviolet (UV) wavebands. Our analysis shows that galaxies experience accelerated evolution as they approach the spine of the filament, suggesting that the intermediate-density environment prevalent in the filaments can accelerate the evolution of galaxies.
Dust mass and dust production efficiencies on the redshift frontier
Authors: Hirashita Hiroyuki , Burgarella Denis , Bouwens Rychard J. 
Published: June 2020

AbstractIn order to clarify the dust production in the early Universe, we constrain the dust mass in high-redshift (z ≳ 5) galaxies using the upper limits obtained by ALMA. We perform fitting to the rest-frame UV–far-infrared spectral energy distribution (SED) of a giant Lyα emitter, Himiko, at z = 6.6 and a composite SED of z > 5 Lyman break galaxies (LBGs). For Himiko, we obtain a high dust temperature > 70 K. This high dust temperature puts a strong upper limit on the total dust mass Md ≲ 2 × 106 M⊙, and the dust mass produced per supernova (SN) md,SN ≲ 0.1 M⊙. Such a low md,SN suggests significant loss of dust by reverse shock destruction or outflow. For the LBG sample, we only obtain an upper limit for md,SN as ∼2 M⊙. This clarifies the importance of observing UV-bright objects (like Himiko) to constrain the dust production by SNe.

AbstractWe present a 4.7σ detection of the [OIII] 88 μm line in a gravitationally-lensed Lyman break galaxy, RXC J2248-ID3, using the Atacama Large Millimeter/submillimeter Array (ALMA). We did not detect [CII] 158 μm and rest-frame 90 μm dust continuum emission, suggesting that the bulk of the interstellar medium (ISM) is ionized. Our two-component SED model combining the previous Hubble Space Telescope (HST) data and new photometry obtained from Very Large Telescope (VLT), Spitzer and ALMA suggests the presence of young (∼2 Myr) and mature (∼600 Myr) stellar components with the metallicity of Z = 0.2Z⊙. Our findings are in contrast with previous results claiming a very young, metal-poor stellar component.

Published: June 2020

AbstractRecently, spectroscopic detections of O[III] 88 μm and Ly-α emission lines from the z ≍ 9.1 galaxy MACS1149-JD1 have been presented, and with these, some interesting properties of this galaxy were uncovered. One such property is that MACS1149-JD1 exhibits a significant Balmer break at around rest-frame 4000 Å, which may indicate that the galaxy has experienced large variations in star formation rate prior to z ∼ 9, with a rather long period of low star formation activity. While some simulations predict large variations in star formation activity in high-redshift galaxies, it is unclear whether the simulations can reproduce the kind of variations seen in MACS1149-JD1. Here, we utilize synthetic spectra of simulated galaxies from two simulation suites in order to study to what extent these can accurately reproduce the spectral features (specifically the Balmer break) observed in MACS1149-JD1. We show that while the simulations used in this study produce galaxies with varying star formation histories, galaxies such as MACS1149-JD1 would be very rare in the simulations. In principle, future observations with the James Webb Space Telescope may tell us if MACS1149-JD1 represents something rare, or if such galaxies are more common than predicted by current simulations.
Probing the ISM of Heiiλ1640 emitters at z = 2–4 via MUSE

Published: June 2020

AbstractHeiiλ1640 emission in the absence of other metal lines is the most sought-after emission line to detect and characterize metal free stellar populations. However, even recent stellar population models with sophisticated treatment of stellar evolution also lack sufficient He+ ionising photons to reproduce observed He 0.1em ii fluxes. We use VLT/MUSE GTO observations to compile a catalogue of 15 z ∼ 2–4 He ii λ1640 emitters from ∼10–30 hour pointings. We show that both He ii λ1640 detections and non-detections occupy similar distribution in UV absolute magnitudes. Rest-UV emission line analysis of our sample shows that the emission lines of our He ii λ1640 emitters are driven by star-formation in solar to moderately sub-solar (∼1/20th) metallicity conditions. However, we find that even after considering effects from binary stars, we are unable to reproduce the He ii λ1640 equivalent widths. Alternative mechanisms are necessary to compensate for the missing He+ ionising photons.
First galaxy SED: Contribution from pre-main-sequence stars
Authors: Mitani Hiroto , Yoshida Naoki , Omukai Kazuyuki , Hosokawa Takashi 
Published: June 2020

AbstractWe calculate the spectral energy distribution of the first galaxies which contain pre-main-sequence stars by using the stellar evolution code Modules for Experiments in Stellar Astrophysics, the spectra model BT-Settl, and the stellar population synthesis code PEGASE. We calculate the galaxy spectral energy distribution for Salpeter Initial Mass Function. We find that very young first galaxies are bright also in mid-infrared, and the contribution of pre-main-sequence stars can be significant over 0.1 Myr after a star-formation episode.
Census of and Lyα, [Oiii]5007, Hα, and [Ciii]158 μm line emission wiht ∼1000 galaxies atz= 4.9 – 7.0 revealed with Subaru/HSC, Spitzer, and ALMA
Authors: Harikane Yuichi 
Published: June 2020

AbstractWe investigate rest-frame UV to far-infrared emission lines and SEDs from 1124 galaxies atz= 4.9 – 7.0. Our sample is composed of 1092 Lyα emitters (LAEs) atz= 4.9–7.0 identified by Subaru/Hyper Suprime-Cam (HSC) narrowband surveys and 34 galaxies atz= 5.148–7.508 with deep [Cii]158μm ALMA data. The SEDs clearly show flux excesses in the Spitzer/IRAC 3.6 and 4.5μm bands, suggesting strong rest-frame optical emission lines of [Oiii] and/or Hα. We model the galaxy SEDs with a flexible code combining stellar population and photoionization models (BEAGLE; Chevallard & Charlot 2016), and investigate relations between the emission lines of Lyα, [Oiii], Hα, and [CII]. We find 1) a positive correlation between the rest-frame Hα equivalent width (EW) and the Lyα, EW,${\EW {^0_Ly\alpha}} $, 2) an interesting turn-over trend that the [Oiii]/Hα flux ratio increases in${\EW {^0_Ly\alpha}} $≃ 0–30 Å, and then decreases out to${\EW {^0_Ly\alpha}} $≃ 130 Å, and 3) a > 99% anti-correlation between a [Cii] luminosity to star-formation rate ratioL[Cii]/SFR) and${\EW {^0_Ly\alpha}} $. Modeling with BEAGLE also suggests that a simple anticorrelation between${\EW {^0_Ly\alpha}} $and metallicity explains self-consistently all of the relations of Lyα, Hα, [Oiii]/Hα, and [Cii] in our study, indicative of detections of very metal-poor (∼0.03Z⊙) galaxies with${\EW {^0_Ly\alpha}} $∼200 Å.
Spatially resolved stellar mass buildup and quenching in massive disk galaxies over the last 10 Gyr revealed with spatially resolved SED fitting
Authors: Abdurro’uf  , Akiyama Masayuki 
Published: June 2020

AbstractDespite decreasing cosmic star formation rate density over the last 10 Gyr, the stellar mass (M*) buildups in galaxies were still progressing during this epoch. About 50% of the current M* density in the universe was built over the last ∼8.7 Gyr. In this research, we investigated the stellar mass buildup and quenching of spatially resolved regions within massive disk galaxies over the last 10 Gyr. We apply the spectral energy distribution (SED) fitting method to SEDs of sub-galactic regions in galaxies to derive the spatially resolved distributions of SFR and M* in the galaxies. This namely pixel-to-pixel SED fitting method is applied to massive disk galaxies at 0.01 < z < 0.02 and 0.8 < z < 1.8. We found that massive disk galaxies tend to build their M* and quench their star formation progressively from the central region to the outskirts, i.e. inside-out stellar mass buildup and quenching.
Which attenuation curves for star-forming galaxies?
Authors: Buat Véronique , Corre David , Boquien Médéric , Małek Katarzyna 
Published: June 2020

AbstractDust attenuation shapes the spectral energy distributions of galaxies and any modelling and fitting procedure of their spectral energy distributions must account for this process. We present results of two recent works dedicated at measuring the dust attenuation curves in star forming galaxies at redshift from 0.5 to 3, by fitting continuum (photometric) and line (spectroscopic) measurements simultaneously with CIGALE using variable attenuation laws based on flexible recipes. Both studies conclude to a large variety of effective attenuation laws with an attenuation law flattening when the obscuration increases. An extra attenuation is found for nebular lines. The comparison with radiative transfer models implies a flattening of the attenuation law up to near infrared wavelengths, which is well reproduced with a power-laws recipe inspired by the Charlot and Fall recipe. Here we propose a global modification of the Calzetti attenuation law to better reproduce the results of radiative transfer models.
Stellar population synthesis of galaxies with chemical evolution model
Authors: Shen Shiyin , Yin Jun 
Published: June 2020

AbstractThe derivation of accurate stellar populations of galaxies is a non-trivial task because of the well-known age-metallicity degeneracy. We aim to break this degeneracy by invoking a chemical evolution model (CEM) for isolated disk galaxy, where its metallicity enrichment history (MEH) is modelled to be tightly linked to its star formation history (SFH). Our CEM has been successfully tested on several local group dwarf galaxies whose SFHs and MEHs have been both independently measured from deep colour-magnitude diagrams of individual stars. By introducing the CEM into the stellar population fitting algorithm as a prior, we expect that the SFH of galaxies could be better constrained.
