Understanding Human Physiological Limitations and Societal Pressures in Favor of Overeating Helps to Avoid Obesity
Authors: Borer Katarina T.
Published: January 2019

Fat gain in our United States (US) environment of over-abundant, convenient, and palatable food is associated with hypertension, cardiovascular disease, diabetes, and increased mortality. Fuller understanding of physiological and environmental challenges to healthy weight maintenance could help prevent these morbidities. Human physiological limitations that permit development of obesity include a predilection to overeat palatable diets, inability to directly detect energy eaten or expended, a large capacity for fat storage, and the difficulty of losing body fat. Innate defenses resisting fat loss include reduced resting metabolism, increased hunger, and high insulin sensitivity, promoting a regain of fat, glycogen, and lean mass. Environmental challenges include readily available and heavily advertised palatable foods, policies and practices that make them abundant, less-than-ideal recommendations regarding national dietary macronutrient intake, and a frequently sedentary lifestyle. After gaining excess fat, some metabolic burdens can be mitigated though thoughtful selection of nutrients. Reduced dietary salt helps lower hypertension, less dietary sugar lowers risk of cardiovascular disease and obesity, and reducing proportion of dietary carbohydrates lowers post-meal insulin secretion and insulin resistance. Food intake and exercise should also be considered thoughtfully, as exercise in a fasted state and before the meals raises glucose intolerance, while exercising shortly after eating lowers it. In summary, we cannot directly detect energy eaten or expended, we have a genetic predisposition to eat palatable diets even when not hungry, and we have a large capacity for fat storage and a difficult time permanently losing excess fat. Understanding this empowers individuals to avoid overeating and helps them avoid obesity.

Introduction: Proteins, particularly whey proteins, represent the most satiating macronutrient in animals and humans. A dietetic regimen based on proteins enriched preload before eating might be a strategy to counteract obesity. Aims and Methods: The aim of the present study was to evaluate the effects of an isocaloric drink containing whey proteins or maltodextrins (preload) on appetite (satiety/hunger measured by a visual analogue scale or VAS), glucometabolic control (blood glucose/insulin), and anorexigenic gastrointestinal peptides (pancreatic polypeptide or PP, glucagon-like peptide 1 or GLP-1 and peptide YY or PYY) in a cohort of obese young women (n = 9; age: 18.1 ± 3.0 years; body mass index, BMI: 38.8 ± 4.5 kg/m2). After two and a half hours, they were administered with a mixed meal at a fixed dose; satiety and hunger were measured by VAS. Results: Each drink significantly augmented satiety and reduced hunger, and the effects were more evident with whey proteins than maltodextrins. Similarly, there were significant increases in GLP-1 and PYY levels (but not PP) after the ingestion of each drink; these anorexigenic responses were higher with whey proteins than maltodextrins. While insulinemia identically increased after each drink, whey proteins induced a lower glycemic response than maltodextrins. No differences in satiety and hunger were found after the meal, which is presumably due to the late administration of the meal test, when the hypophagic effect of whey proteins was disappearing. Conclusions: While whey proteins actually reduce appetite, stimulate anorexigenic gastrointestinal peptides, and improve glucometabolic homeostasis in young obese women, further additional studies are mandatory to demonstrate their hypophagic effects in obese subjects, when administered as preload before eating.
Investigating Items to Improve the Validity of the Five-Item Healthy Eating Score Compared with the 2015 Healthy Eating Index in a Military Population

Published: January 2019

Military researchers utilize a five-item healthy eating score (HES-5) in the Global Assessment Tool (GAT) questionnaire to quickly assess the overall diet quality of military personnel. This study aimed to modify the HES-5 to improve its validity relative to the 2015 Healthy Eating Index (HEI-2015) in active duty military personnel (n = 333). A food frequency questionnaire was used to calculate HEI-2015 scores and to assess sugar-sweetened beverage (SSB) intake in 8-oz (SSB-8) and 12-oz servings. GAT nutrition questions were used to calculate HES-5 scores and capture breakfast and post-exercise recovery fueling snack (RFsnack) frequencies. Two scoring options were considered for the highest RFsnack category: “4” vs. “5” (RFsnack-5). Potential candidates were added alone and in combination to the HES-5 and compared to the HEI-2015 with a Pearson correlation coefficient. Scores with the highest correlations were compared via a z-score equation to identify the simplest modification to the HES-5. Correlations between HES-5 and HEI-2015 scores in total participants, males, and females were 0.41, 0.45 and 0.32, respectively. Correlations were most significantly improved in total participants by adding RFsnack-5, SSB-8, RFsnack-5 + SSB-8, and RFsnack-5 + SSB-8 + breakfast, though the addition of SSB-8 + RFsnack-5 performed best (r = 0.53). Future work should consider scoring mechanisms, serving sizes, and question wording.
Can the Efficacy of [18F]FDG-PET/CT in Clinical Oncology Be Enhanced by Screening Biomolecular Profiles?
Authors: O’Neill Hazel , Malik Vinod , Johnston Ciaran , Reynolds John V , O’Sullivan Jacintha
Published: January 2019

Positron Emission Tomography (PET) is a functional imaging modality widely used in clinical oncology. Over the years the sensitivity and specificity of PET has improved with the advent of specific radiotracers, increased technical accuracy of PET scanners and incremental experience of Radiologists. However, significant limitations exist—most notably false positives and false negatives. Additionally, the accuracy of PET varies between cancer types and in some cancers, is no longer considered a standard imaging modality. This review considers the relative influence of macroscopic tumour features such as size and morphology on 2-Deoxy-2-[18F]fluoroglucose ([18F]FDG) uptake by tumours which, though well described in the literature, lacks a comprehensive assessment of biomolecular features which may influence [18F]FDG uptake. The review aims to discuss the potential influence of individual molecular markers of glucose transport, glycolysis, hypoxia and angiogenesis in addition to the relationships between these key cellular processes and their influence on [18F]FDG uptake. Finally, the potential role for biomolecular profiling of individual tumours to predict positivity on PET imaging is discussed to enhance accuracy and clinical utility.

Published: January 2019

Glycoside Hydrolase 3 (GH3), a member of the Auxin-responsive gene family, is involved in plant growth, the plant developmental process, and various stress responses. The GH3 gene family has been well-studied in Arabidopsis thaliana and Zea mays. However, the evolution of the GH3 gene family in Oryza species remains unknown and the function of the GH3 gene family in Oryza sativa is not well-documented. Here, a systematic analysis was performed in six Oryza species/subspecies, including four wild rice species and two cultivated rice subspecies. A total of 13, 13, 13, 13, 12, and 12 members were identified in O. sativa ssp. japonica, O. sativa ssp. indica, Oryza rufipogon, Oryza nivara, Oryza punctata, and Oryza glumaepatula, respectively. Gene duplication events, structural features, conserved motifs, a phylogenetic analysis, chromosome locations, and Ka/Ks ratios of this important family were found to be strictly conservative across these six Oryza species/subspecies, suggesting that the expansion of the GH3 gene family in Oryza species might be attributed to duplication events, and this expansion could occur in the common ancestor of Oryza species, even in common ancestor of rice tribe (Oryzeae) (23.07~31.01 Mya). The RNA-seq results of different tissues displayed that OsGH3 genes had significantly different expression profiles. Remarkably, the qRT-PCR result after NaCl treatment indicated that the majority of OsGH3 genes play important roles in salinity stress, especially OsGH3-2 and OsGH3-8. This study provides important insights into the evolution of the GH3 gene family in Oryza species and will assist with further investigation of OsGH3 genes’ functions under salinity stress.

Black pepper (Piper nigrum L.) is a tropical crop with extensive medicinal potential in ethnomedicine and nutraceutical applications. The essential oil of black pepper finds wide applications in inhabitation of respiratory infections and soothing of muscular pains due to its warming and energizing property. The pungent bioactive piperine is responsible for this function, and therefore, efficient technology is required for an optimal extraction process of this compound. In the present article, we have developed a procedure for extracting black pepper essential oil from Vietnam, optimizing conditions that affect the extraction process. The effect of process parameters, namely material size, preservation method, the concentration of sodium chloride, the concentration of soak time, the ratio of material to water, temperature extraction, time extraction on the extraction yield, and relative efficiency were investigated. Results demonstrated that 20 g of black pepper milled with a mesh size of 160 obtained 0.48 g of essential oil (2.4%) at a raw material to water ratio of 1/21 (g/mL) at 150 °C in a time of 5.2 h. GC-MS (Gas chromatography–mass spectrometry) spectra showed that 3-carene (29.21%), D-limonene (20.94%), caryophyllene (15.05%), and β-pinene (9.77%) were present as major components. These results suggested that the essential oil extracted from Vietnamese black pepper is applicable in the manufacturing processes of insecticides and air deodorizers.
Sex-Specific Proteomic Changes Induced by Genetic Deletion of Fibroblast Growth Factor 14 (FGF14), a Regulator of Neuronal Ion Channels

Published: January 2019

Fibroblast growth factor 14 (FGF14) is a member of the intracellular FGFs, which is a group of proteins involved in neuronal ion channel regulation and synaptic transmission. We previously demonstrated that male Fgf14−/− mice recapitulate the salient endophenotypes of synaptic dysfunction and behaviors that are associated with schizophrenia (SZ). As the underlying etiology of SZ and its sex-specific onset remain elusive, the Fgf14−/− model may provide a valuable tool to interrogate pathways related to disease mechanisms. Here, we performed label-free quantitative proteomics to identify enriched pathways in both male and female hippocampi from Fgf14+/+ and Fgf14−/− mice. We discovered that all of the differentially expressed proteins measured in Fgf14−/− animals, relative to their same-sex wildtype counterparts, are associated with SZ based on genome-wide association data. In addition, measured changes in the proteome were predominantly sex-specific, with the male Fgf14−/− mice distinctly enriched for pathways associated with neuropsychiatric disorders. In the male Fgf14−/− mouse, we found molecular characteristics that, in part, may explain a previously described neurotransmission and behavioral phenotype. This includes decreased levels of ALDH1A1 and protein kinase A (PRKAR2B). ALDH1A1 has been shown to mediate an alternative pathway for gamma-aminobutyric acid (GABA) synthesis, while PRKAR2B is essential for dopamine 2 receptor signaling, which is the basis of current antipsychotics. Collectively, our results provide new insights in the role of FGF14 and support the use of the Fgf14−/− mouse as a useful preclinical model of SZ for generating hypotheses on disease mechanisms, sex-specific manifestation, and therapy.

Published: January 2019

Neonatal hearing loss is one of the most common anomalies and is frequently associated with delivery problems. The effects of growth hormone (GH) on brain regeneration after an injury are well known. This paper looks at a male child diagnosed with cerebral palsy, psychomotor affectation, left spastic hemiparesis, and bilateral sensorineural hearing loss after fetal distress due to ruptured membranes before the delivery of more than 30 hours of evolution and several episodes of severe hypoglycemia. From 3.5 months of age, we treated him with GH (0.04 mg/kg/day), Melatonin (5 mg/day and 6 months later 10 mg/day) and rehabilitation, for a period of 14 months; at discharge, the child fully recovered all the disabilities produced by his cerebral palsy, including normal hearing; GMFM-88 increased from 7.84% to 48.23%; Battelle scores increased from 2 to 9 after 7 months of treatment, and to 30, 1 year after discharge. Most likely hearing loss was recovered due to the effect of GH on the production of hair cells from stem cells (only present in very young children) in the cochlear sensory epithelium. This is the first case of recovery of hearing loss in humans after GH administration. Moreover, GH administration is useful and safe for early treatment of cerebral palsy.
MHD Stagnation Point Flow of Nanofluid on a Plate with Anisotropic Slip
Authors: Sadiq Muhammad Adil
Published: January 2019

In this article, an axisymmetric three-dimensional stagnation point flow of a nanofluid on a moving plate with different slip constants in two orthogonal directions in the presence of uniform magnetic field has been considered. The magnetic field is considered along the axis of the stagnation point flow. The governing Naiver–Stokes equation, along with the equations of nanofluid for three-dimensional flow, are modified using similarity transform, and reduced nonlinear coupled ordinary differential equations are solved numerically. It is observed that magnetic field M and slip parameter λ 1 increase the velocity and decrease the boundary layer thickness near the stagnation point. Also, a thermal boundary layer is achieved earlier than the momentum boundary layer, with the increase in thermophoresis parameter N t and Brownian motion parameter N b . Important physical quantities, such as skin friction, and Nusselt and Sherwood numbers, are also computed and discussed through graphs and tables.
Comparative Overview of the Mechanisms of Action of Hormones and Endocrine Disruptor Compounds
Authors: Combarnous Yves , Nguyen Thi Mong Diep
Published: January 2019

Endocrine Disruptor Compounds (EDCs) are synthetic or natural molecules in the environment that promote adverse modifications of endogenous hormone regulation in humans and/or in wildlife animals. In the present paper, we review the potential mechanisms of EDCs and point out the similarities and differences between EDCs and hormones. There was only one mechanism, out of nine identified, in which EDCs acted like hormones (i.e., binding and stimulated hormone receptor activity). In the other eight identified mechanisms of action, EDCs exerted their effects either by affecting endogenous hormone concentration, or its availability, or by modifying hormone receptor turn over. This overview is intended to classify the various EDC mechanisms of action in order to better appreciate when in vitro tests would be valid to assess their risks towards humans and wildlife.
Evolutionary Ecology of Fish Venom: Adaptations and Consequences of Evolving a Venom System
Authors: Harris Richard J. , Jenner Ronald A.
Published: January 2019

Research on venomous animals has mainly focused on the molecular, biochemical, and pharmacological aspects of venom toxins. However, it is the relatively neglected broader study of evolutionary ecology that is crucial for understanding the biological relevance of venom systems. As fish have convergently evolved venom systems multiple times, it makes them ideal organisms to investigate the evolutionary ecology of venom on a broader scale. This review outlines what is known about how fish venom systems evolved as a result of natural enemy interactions and about the ecological consequences of evolving a venom system. This review will show how research on the evolutionary ecology of venom in fish can aid in understanding the evolutionary ecology of animal venoms more generally. Further, understanding these broad ecological questions can shed more light on the other areas of toxinology, with applications across multiple disciplinary fields.
BmTudor-sn Is a Binding Protein of Destruxin A in Silkworm Bm12 Cells
Authors: Wang Jingjing , Hu Weina , Hu Qiongbo
Published: January 2019

Destruxin A (DA), a hexa-cyclodepsipeptidic mycotoxin secreted by the entomopathogenic fungus Metarhizium anisopliae, was reported to have an insecticidal effect and anti-immunity activity. However, its molecular mechanism of action remains unclear. Previously, we isolated several potential DA-affinity (binding) proteins in the Bombyx mori Bm12 cell line. By docking score using MOE2015, we selected three proteins—BmTudor-sn, BmPiwi, and BmAGO2—for further validation. First, using Bio-Layer Interferometry in vitro, we found that BmTudor-sn had an affinity interaction with DA at 125, 250, and 500 µM, while BmPiwi and BmAGO2 had no interaction signal with DA. Second, we employed standard immunoblotting to verify that BmTudor-sn is susceptible to DA, but BmPiwi and BmAGO2 are not. Third, to verify these findings in vivo, we used a target engagement strategy based on shifts in protein thermal stability following ligand binding termed the cellular thermal shift assay and found no thermal stability shift in BmPiwi and BmAGO2, whereas a shift was found for BmTudor-sn. In addition, in BmTudor-sn knockdown Bm12 cells, we observed that cell viability increased under DA treatment. Furthermore, insect two-hybrid system results indicated that the key site involved in DA binding to BmTudor-sn was Leu704. In conclusion, in vivo and in vitro experimental evidence indicated that BmTudor-sn is a binding protein of DA in silkworm Bm12 cells at the 100 µM level, and the key site of this interaction is Leu704. Our results provide new perspectives to aid in elucidating the molecular mechanism of action of DA in insects and developing new biopesticide.
Regional Flood Frequency Analysis of the Pannonian Basin
Authors: Leščešen Igor , Dolinaj Dragan
Published: January 2019

In this paper, we performed Regional Flood Frequency Analysis (RFFA) by using L-moments and Annual Maximum Series (AMS) methods. Time series of volumes and duration of floods were derived using the threshold level method for 22 hydrological stations in the Pannonian Basin. For flood definition, a threshold set at Q10 was used. The aim of this research is to derive best-fit regional distribution for the four major rivers within the Pannonian Basin and to provide reliable prediction of flood quantiles. The results show that the investigated area can be considered homogeneous (Vi < 1) both for flood volumes (0.097) and durations (0.074). To determine the best-fit regional distribution, the six most commonly used distributions were used. Results obtained by L-moment ratio diagram and Z statistics show that all distributions satisfy the test criteria, but because the Log-Normal distribution has the value closest to zero, it can be selected as the best-fit distribution for the volumes (0.12) and durations (0.25) of floods.
Search for Sodium-rich Stars among Metal-poor Stars*
Authors: Pereira C. B. , Holanda N. , Drake N. A. , Roig F.
Published: January 2019

Sodium-rich stars are often found in globular clusters giants. However, some sodium-rich stars have been found among field metal-poor stars. These stars are considered as evaporated from globular clusters. Identified such kind of stars among the field stars in the Galaxy may provide insights of which mechanism was responsible for the ejection from a globular cluster and may reveal some chemical peculiarity. Therefore, we started a search, using high-resolution spectroscopy, among metal-poor stars from several sources of the literature to find a sodium-rich star. Here we present the results for the temperature, gravity, metallicity, and sodium abundances for the stars of our sample. For many of them we determined the temperature, gravity, metallicity, and sodium abundances for the first time. As a result of our search we found one star, CD-23°16310, which has a [Na/Fe] ratio of +1.09. We also show that CD-23°16310 is not a carbon-enhanced metal-poor (CEMP) star since carbon is not enriched but is nitrogen-rich. We did not detect any variation of the radial velocity that would support the hypothesis of mass transfer. Thus, the high sodium and nitrogen abundance could be due to a strong internal mixing process, suggesting that CD-23°16310 is an early asymptotic giant branch star.
Instabilities in the Early Solar System Due to a Self-gravitating Disk
Authors: Quarles B. , Kaib N.
Published: January 2019

Modern studies of the early solar system routinely invoke the possibility of an orbital instability among the giant planets triggered by gravitational interactions between the planets and a massive exterior disk of planetesimals. Previous works have suggested that this instability can be substantially delayed (about hundreds of megayears) after the formation of the giant planets. Bodies in the disk are typically treated in a semi-active manner, wherein their gravitational force on the planets is included, but interactions between the planetesimals are ignored. We perform N-body numerical simulations using GENGA, which makes use of GPUs to allow for the inclusion of all gravitational interactions between bodies. Although our simulated Kuiper Belt particles are more massive than the probable masses of real primordial Kuiper Belt objects, our simulations indicate that the self-stirring of the primordial Kuiper Belt is very important to the dynamics of the giant planet instability. We find that interactions between planetesimals dynamically heat the disk and typically prevent the outer solar system’s instability from being delayed by more than a few tens of megayears after giant planet formation. Longer delays occur in a small fraction of systems that have at least 3.5 au gaps between the planets and planetesimal disk. Our final planetary configurations match the solar system at a rate consistent with other previous works in most regards. Pre-instability heating of the disk typically yields final Jovian eccentricities comparable to the modern solar system’s value, which has been a difficult constraint to match in past works.
Multi-frequency Variability Study of Ton 599 during the High Activity of 2017
Authors: Prince Raj
Published: January 2019

In this work, I have presented a multi-frequency variability and correlation study of the blazar Ton 599, which was observed for the first time in the flaring state at the end of 2017. Data from Fermi-LAT, Swift-XRT/UVOT, Steward observatory, and Owens Valley Radio Observatory(OVRO) (15 GHz) are used and it is found that the source is more variable in γ-rays and optical/UV than in X-rays and radio. Large variations in degree of polarization and position angle are observed during the flaring period. Maximum flux during the γ-ray flare is found to be 12.63 × 10−7 at MJD 58057.5 from the 1 day bin light curve, which is the highest flux ever achieved by this source. It is further found that all the peaks of the flare are very symmetric, which suggests the cooling time of electrons is much smaller than the light-crossing time. Using 1 day as a fast variability time, the size of the γ-ray emission region is estimated as 1.88 × 1016 cm. Two 42 GeV of photons are detected during the flare, which puts a constraint on the location of the emission region, and it is found that the γ-ray emitting blob is located at the outer edge or outside the broad-line region. The trend of increasing fractional variability toward higher energies is also seen. Strong correlations were seen between γ-ray, optical/UV, X-ray, and radio (15 GHz) emission. A small time lag between γ-rays and the optical/UV suggests their emission to be co-spatial, while the lag of 27 days between γ-rays and OVRO (15 GHz) suggests two different emission zones separated by a distance of ∼5 pc.

Published: January 2019

We develop a framework for joint constraints on the CO luminosity function based on power spectra (PS) and voxel intensity distributions (VID) and apply this to simulations of CO Mapping Array Pathfinder (COMAP), a CO intensity mapping experiment. This Bayesian framework is based on a Markov chain Monte Carlo (MCMC) sampler coupled to a Gaussian likelihood with a joint PS + VID covariance matrix computed from a large number of fiducial simulations and re-calibrated with a small number of simulations per MCMC step. The simulations are based on dark matter halos from fast peak patch simulations combined with the L
CO(M
halo) model of Li et al. We find that the relative power to constrain the CO luminosity function depends on the luminosity range of interest. In particular, the VID is more sensitive at large luminosities, while the PS and the VID are both competitive at small and intermediate luminosities. The joint analysis is superior to using either observable separately. When averaging over CO luminosities ranging between

, and over 10 cosmological realizations of COMAP Phase 2, the uncertainties (in dex) are larger by 58% and 30% for the PS and VID, respectively, when compared to the joint analysis (PS + VID). This method is generally applicable to any other random field, with a complicated likelihood, as long a fast simulation procedure is available.
Anchoring Magnetic Fields in Turbulent Molecular Clouds. II. From 0.1 to 0.01 pc
Authors: Zhang Y. , Guo Z. , Wang H. H. , Li H-b
Published: January 2019

We compared the magnetic field directions inferred from polarimetry data obtained from 100 pc scale inter-cloud media (ICM) and from subparsec scale molecular cloud cores. The highly correlated result led us to conclude that cloud turbulence must be sub-Alfvénic. Here we extend the study with 0.01 pc cores observed by interferometers. The inferred field directions at this scale significantly deviate from that of the surrounding ICM. An obvious question to ask is whether this high-resolution result contradicts the sub-Alfvénic picture concluded earlier. We performed MHD simulations of a slightly super-critical (magnetic criticality = 2) clouds with Alfvénic Mach number M
A = 0.63 (M

means the average within the entire simulated volume; e.g., Burkhart et al. 2009), which can reproduce the Paper I results, and observed the development toward smaller scales. Interestingly, all subregions hosting cores with n
H2 > 105/cc (the typical density observed by interferometers) possess M
A = 2–3. Not too surprisingly, these slightly super-Alfvénic cores result in B-field orientation offsets comparable to the interferometer observations. The result suggests that gravity can concentrate (and maybe also contribute to, which requires further study to confirm) turbulent energy and create slightly super-Alfvénic cores out of sub-Alfvénic clouds. The results of our simulations also agree with the observed velocity-scale, mass-scale, and field-density relations.

The PERLAS potential has been successfully used in many studies related to the dynamics of the spiral arms on the equatorial plane of normal (nonbarred) spiral galaxies. In the present work, we extend these studies by investigating the three-dimensional (3D) dynamics of the spiral arms in the same type of potential. We consider a typical open, logarithmic, spiral pattern of pitch angle 25° and we examine the stellar orbits that can support it as the ratio of the masses of the spiral over the disk component (M

d
ratio increases. We find that a bisymmetric spiral with 25° pitch angle is better supported by orbits in models with

. In these cases, a strong spiral pattern is supported between the radial 2:1 and 4:1 resonances, whereas local enhancements of the imposed spirals are encountered in some models between 4:1 and corotation. A characteristic barlike structure is observed in all models at radii smaller than the radius of the 2:1 resonance.
A Novel Approach to Constrain Rotational Mixing and Convective-core Overshoot in Stars Using the Initial–Final Mass Relation
Authors: Cummings Jeffrey D. , Kalirai Jason S. , Choi Jieun , Georgy C. , Tremblay P.-E. , Ramirez-Ruiz Enrico
Published: January 2019

The semi-empirical initial–final mass relation (IFMR) connects spectroscopically analyzed white dwarfs (WDs) in star clusters to the initial masses of the stars that formed them. Most current stellar evolution models, however, predict that stars will evolve to WDs ∼0.1 M
⊙ less massive than that found in the IFMR. We first look at how varying theoretical mass-loss rates, third dredge-up efficiencies, and convective-core overshoot may help explain the differences between models and observations. These parameters play an important role at the lowest masses (M
initial < 3 M
⊙). At higher masses, only convective-core overshoot meaningfully affects WD mass, but alone it likely cannot explain neither the observed WD masses nor why the IFMR scatter is larger than observational errors predict. These higher masses, however, are also where rotational mixing in main sequence stars begins to create more massive cores, and hence more massive WDs. This rotational mixing also extends a star's lifetime, making faster-rotating progenitors appear like less massive stars in their semi-empirical age analysis. Applying the observed range of young B-dwarf rotations to the MIST or SYCLIST rotational models demonstrates a marked improvement in reproducing both the observed IFMR data and its scatter. The incorporation of both rotation and efficient convective-core overshoot significantly improves the match with observations. This Letter shows that the IFMR provides a valuable observational constraint on how rotation and convective-core overshoot affect the core evolution of a star.
Collembola of Canada
Authors: Turnbull Matthew S. , Stebaeva Sophya
Published: January 2019

The state of knowledge of diversity of Collembola in Canada was assessed by examination of literature and DNA barcode data. There are 474 described extant Collembola species known from Canada, a significant change compared to the 520 species estimated to occur in Canada in 1979 (Richards 1979) and the 341 reported in the most recent national checklist (Skidmore 1993). Given the number of indeterminate or cryptic species records, the dearth of sampling in many regions, and the growing use of genetic biodiversity assessment methods such as Barcode Index Numbers, we estimate the total diversity of Collembola in Canada to be approximately 675 species. Advances in Collembola systematics and Canadian research are discussed.
Megaloptera of Canada

An updated summary on the fauna of Canadian Megaloptera is provided. Currently, 18 species are recorded in Canada, with six species of Corydalidae and 12 species of Sialidae. This is an increase of two species since 1979. An additional seven species are expected to be discovered in Canada. Barcode Index Numbers are available for ten Canadian species.
Grylloblattodea of Canada
Authors: Schoville Sean D.
Published: January 2019

The enigmatic insect order Grylloblattodea comprises two described species in Canada, which are limited to the Montane Cordillera and Pacific Maritime ecozones. One of the described species has three Canadian subspecies of uncertain taxonomic ranking, and there are two additional undescribed or unreported species known in close proximity to the Canadian border in western Alberta and British Columbia that likely also occur in Canada. Thus, as much as 50% of the total taxonomic diversity of Grylloblattodea in Canada is still undocumented. Targeted surveys and taxonomic work, as well as studies that describe the ecology and conservation status of Grylloblattodea are important goals for future research.

Numbers of species currently known from Canada, total Barcode Index Numbers (BINs), and estimated numbers of undescribed or unrecorded species are provided for each family. An overview of recent changes in the systematics and Canadian faunistics of major groups is provided as well as some general information on biology and life history. A total of 116 families and 9620 described species of Canadian Diptera are reported, representing more than a 36% increase in species numbers since the last comparable assessment by JF McAlpine et al. (1979). Almost 30,000 BINs have so far been obtained from flies in Canada. Estimates of additional number of species remaining to be documented in the country range from 5200 to 20,400.
The diversity of terrestrial arthropods in Canada
Authors: Langor David W.
Published: January 2019

Based on data presented in 29 papers published in theBiota of CanadaSpecial Issue of ZooKeys and data provided herein about Zygentoma, more than 44,100 described species of terrestrial arthropods (Arachnida, Myriapoda, Insecta, Entognatha) are now known from Canada. This represents more than a 34% increase in the number of described species reported 40 years ago (Danks 1979a). The most speciose groups are Diptera (9620 spp.), Hymenoptera (8757), and Coleoptera (8302). Less than 5% of the fauna has a natural Holarctic distribution and an additional 5.1% are non-native species. A conservatively estimated 27,000–42,600 additional species are expected to be eventually discovered in Canada, meaning that the total national species richness is ca. 71,100–86,700 and that currently 51–62% of the fauna is known. Of the most diverse groups, those that are least known, in terms of percent of the Canadian fauna that is documented, are Acari (31%), Thysanoptera (37%), Hymenoptera (46%), and Diptera (32–65%). All groups but Pauropoda have DNA barcodes based on Canadian material. More than 75,600 Barcode Index Numbers have been assigned to Canadian terrestrial arthropods, 63.5% of which are Diptera and Hymenoptera. Much work remains before the Canadian fauna is fully documented, and this will require decades to achieve. In particular, greater and more strategic investment in surveys and taxonomy (including DNA barcoding) is needed to adequately document the fauna.
Boréalisme. Pour un atlas sensible du Nord
Authors: Briens Sylvain
Published: January 2019

L’article se propose d’établir, en forgeant le terme de boréalisme , un programme de recherche dont l’ambition serait de tracer l’histoire des déplacements, des transformations, des circulations qui se réfèrent au « Nord ». Dépassant la définition d’un boréalisme comme transposition de l’orientalisme, il explore les cadres conceptuels d’un tel programme et croise les outils épistémologiques que les sciences historiques, la géographie, la littérature comparée et plus généralement l’histoire culturelle ont développés dans le domaine de l’histoire des représentations. Le boréalisme apparaît alors comme un cadre pour penser une conceptualité spatiale qui refuse une essentialisation du « Nord » et de l’imaginaire collectif qui lui est associé, et pour saisir un processus dynamique qui redéfinit le « Nord » à chaque énonciation.
Asger Jorn et l’Institut Scandinave de Vandalisme Comparé. La création d’un boréalisme endogène
Authors: Jamet Raphaëlle
Published: January 2019

Asger Jorn, artiste danois, crée au début des années 1960 l’Institut Scandinave de Vandalisme Comparatif. Que signifie ce projet qui met en relation l’art populaire nordique, l’archéologie et les dernières évolutions de l’avant-garde artistique ? Cet espace hybride peut être difficile à cerner tant il déploie ses activités à travers les frontières à la fois géographiques, conceptuelles et disciplinaires. Le concept de boréalisme , présenté dans cet ouvrage, met en lumière que, par ce projet, Asger Jorn tente d’apporter une réponse complexe à la fois à l’actualité politique, artistique et scientifique. Partant d’une prise de conscience des effets d’une représentation du Nord subie dans un contexte historique et géopolitique mouvementé, il poursuit un travail engagé dans l’avant-garde artistique de l’après-guerre en se réappropriant les concepts de centre et de périphérie pour finalement par le biais de la double figure de l’artiste et du scientifique insuffler une nouvelle puissance et révéler des « Nords » d’ores et déjà présents dans la culture mondiale.
La transparence est notre censure
Authors: Alloa Emmanuel
Published: January 2019

Contrairement à ce qu’on continue d’affirmer, l’âge de la censure n’a pas été remplacé par un âge de la transparence. Dans les régimes post-répressifs qui caractérisent nos sociétés, la transparence représente une forme nouvelle, particulièrement efficace – car imperceptible – de censure. Si la nature de ce nouveau mécanisme de sélection nous échappe encore, c’est parce que nous restons prisonniers d’une conception moderne – et prohibitive – de ce qu’est la censure. Pourtant, à ses origines, l’institution du «  census  » n’avait pas pour but d’interdire mais de recenser les vies afin de les gouverner plus efficacement.
L’Index des clés performatives
Authors: Tkacz Nathaniel , Citton Yves
Published: January 2019

D’où vient la transparence et où va-t-elle ? Quelles sont ses méthodes ? Quels types de savoirs doivent être constitués pour nous la fournir ? Cet article propose la description d’un tableau de bord informationnel, c’est-à-dire d’une interface de plus en plus souvent déployée dans les initiatives relevant de la transparence. Cet Index des Clés Performatives aide à percevoir l’emprise des régimes de mesure et de gestion de performance sur notre monde. Pour expliquer le parcours allant de la transparence à la gestion de performance à travers les tableaux de bord, cet article revient sur un scandale récent de la politique britannique qui a déclenché une nouvelle poussée d’appels à la transparence, et finalement à la multiplication des tableaux de bords.
La grève des camionneurs au Brésil
Authors: Naback Clarissa , Mendes Alexandre
Published: January 2019

L’article analyse la grève des camionneurs au Brésil, à partir de la centralité de la logistique en tant que terrain de lutte et d’accumulation dans le capitalisme contemporain. Dans le cas du Brésil, l’interruption complète de la provision d’intrants de base et l’occupation de routes dans tout le pays signifiaient la fin d’un cycle politico-économique basé sur la fausse alternative entre le néolibéralisme et le développementisme progressiste. La lutte des camionneurs, bien que ambiguë et contradictoire, révèle l’urgence pour nouvelles formes de protection sociale et concrète, de valorisation des revenus et de la vie dans le cadre des luttes de la logistique.
« La table du Seigneur »
Authors: Boselli Goffredo , Caldiroli Daniela
Published: January 2019

Le renouvellement de la façon concrète de célébrer l’eucharistie, dont un besoin urgent se fait largement sentir aujourd’hui, pourra se réaliser dans la mesure où l’on reviendra à l’Évangile, afin d’y vérifier nos concepts, d’y juger nos pratiques pour les rendre vivantes. La voie pour renouveler la pratique eucharistique sera de poursuivre sans crainte le chemin de conversion évangélique commencée avec la réforme liturgique du concile Vatican II. Esquisser un style d’eucharistie pour le christianisme qui nous attend, signifie retrouver une vérité réellement chrétienne, car véritablement évangélique, une vérité que la théologie eucharistique ainsi que la pratique liturgique sont aujourd’hui appelées à redécouvrir et à s’approprier : cette vérité est contenue dans l’expression paulinienne « la table du Seigneur » (1 Co 10, 21). La communauté chrétienne est une communauté de table.
Sites of rare form of auricula (Primula auricula var. tolminensis nom. prov.) in the southern Julian Alps / Rastišča redke oblike lepega jegliča (Primula auricula var. tolminensis nom. prov.) v južnih Julijskih Alpah

Abstract In the southern Julian Alps under the northwestern ridge of Kobilja Glava above the pasture of Lom and on the slopes of Krikov Vrh between pastures of Lom and Kuk (Podkuk), on stony shady pasturelands and in limestone and dolomite rocks at elevations ranging between 1,100 and 1,200 m, two forms of auricula (Primula auricula) occur side by side. The more common specimens with bright (deep) yellow flowers are accompanied and outnumbered by plants with slightly smaller stems and distinctly pale, lemon-coloured flowers. Although Primula auricula as a species boasts impressive variability in the size and shape of leaves and their meal covering, as well as in the size and colour of flowers, we have not observed populations with such distinctly pale yellow flowers anywhere else in Slovenia. The taxa described elsewhere in the distribution area of Primula auricula s. lat. (including those that supposedly belong to Primula lutea) are distinctly different from the studied auriculas, at least in terms of flower colour. We infer that they are a new variety, Primula auricula var. tolminensis (the Tolmin auricula), but will have to conduct further research to corroborate this conclusion. In this paper we describe its sites and current distribution. Key words: flora, taxonomy, infraspecies variability, phytosociology, Primula auricula, Kobilja Glava, Julian Alps, Slovenia IzvlečekV južnih Julijskih Alpah, pod severozahodnim grebenom Kobilje glave nad planino Lom in na pobočjih Krikovega vrha med to planino in planino Kuk (Podkuk) na kamnitih osojnih pašnikih in v apnenčastem in dolomitnem skalovju na nadmorski višini med 1100 m in 1200 m skupaj rasteta dve obliki lepega jegliča (Primula auricula). Poleg običajno živo (temno) rumeno cvetočih primerkov, ki so v manjšini, prevladujejo rastline z nekoliko manjšimi stebli in cvetovi, ki imajo izrazito svetlorumeno, limonasto barvo. Čeprav je za vrsto Primula auricula značilna velika variabilnost glede velikosti in oblike listov in njihovega poprha, kot tudi glede velikosti in barve cvetov, takih izrazito svetlorumeno cvetočih populacij drugje v Sloveniji do zdaj nismo opazili. Tudi taksoni, ki so opisani drugod v območju areala vrste Primula auricula s. lat. (tudi tisti, ki naj bi pripadali vrsti Primula lutea) se vsaj v barvnem odtenku cvetov od preučenih avrikljev očitno razlikujejo. Sklepamo, da gre za novo varieteto Primula auricula var. tolminensis, slovensko jo imenujemo tolminski jeglič, kar pa bomo morali v nadaljnjih raziskavah še potrditi. V prispevku opisujemo njena rastišča in do zdaj znano razširjenost. Ključne besede: flora, taksonomija, znotrajvrstna variabilnost, fiteconeologija, Primula auricula, Kobilja glava, Julijske Alpe, Slovenija

Una ensalada anónima del siglo XVII de los Romances y letras de a tres vozes (Biblioteca Nacional de Madrid)
Authors: Lambea Mariano
Published: January 2019

Procedentes del Fondo Barbieri y bajo las signaturas M. 1370, M. 1371 y M. 1372, se conservan en la Biblioteca Nacional de Madrid tres volúmenes manuscritos , en su mayor parte de polifonía profana, pertenecientes a las primeras décadas del siglo XVII. Aproximadamente la primera mitad de las piezas de esta compilación fueron publicadas por Miguel Querol en un único tomo, sin que hasta la fecha hayan visto la luz las restantes composiciones, al menos, agrupadas en un segundo volumen. Entre éstas, en las páginas 95-97 de los citados manuscritos, figura una "Ensalada a 3" de autor anónimo, que viene a engrosar el reducido, pero valioso, repertorio musical que poseemos hasta el momento sobre este género literariomusical tan típicamente hispánico, ya que, si atendemos al número de obras conservadas, las fuentes literarias que contienen ensaladas y ensaladillas han llegado siempre hasta nosotros en mayor medida que las fuentes específicamente musicales.
Apuntes para la evaluación de la actividad de las Sociedades Musicales en España (1921-1925)
Authors: Pérez Zalduondo Gemma
Published: January 2019

Adolfo Salazar, en 1930, definió las sociedades filarmónicas como "los principales órganos de difusión de la música en España", indicando así la innegable importancia de las mismas para el conocimiento de la evolución musical de comienzos del Siglo XX en nuestro país. A pesar de ello, existen escasos aportes documentales sobre el tema. En el presente artículo pretendemos ofrecer y analizar datos parciales sobre la actividad de la Sociedad Filarmónica de Madrid y la Sociedad Sevillana de Conciertos, junto a otros pertenecientes a asociaciones musicales de diversa índole. Todos los datos corresponden a las temporadas concertísticas de los años 1921 a 1925 , período en el que se produjeron acontecimientos tan significativos como el estreno de El Retablo de Maese Pedro en ambas Sociedades y las visitas de Wanda Landowska y Arthur Rubinstein a Sevilla. Hemos centrado nuestro análisis en: la programación de las temporadas de conciertos; los intérpretes contratados; la clasificación estilística del repertorio; la presencia de la música española y la novedad de las obras ejecutadas.
