description: The evolution of the metal content of galaxies and its relations to other global properties [such as total stellar mass (M*), circular velocity, star formation rate (SFR), halo mass, etc.] provides important constraints on models of galaxy formation. Here we examine the evolution of metallicity scaling relations of simulated galaxies in the Galaxies-Intergalactic Medium Interaction Calculation suite of cosmological simulations. We make comparisons to observations of the correlation of gas-phase abundances with M* (the mass-metallicity relation, MZR), as well as with both M* and SFR or gas mass fraction (the so-called 3D fundamental metallicity relations, FMRs). The simulated galaxies follow the observed local MZR and FMRs over an order of magnitude in M*, but overpredict the metallicity of massive galaxies (log M* > 10.5), plausibly due to inefficient feedback in this regime. We discuss the origin of the MZR and FMRs in the context of galactic outflows and gas accretion. We examine the evolution of mass-metallicity relations defined using different elements that probe the three enrichment channels (SNII, SNIa, and AGB stars). Relations based on elements produced mainly by SNII evolve weakly, whereas those based on elements produced preferentially in SNIa/AGB exhibit stronger evolution, due to the longer timescales associated with these channels. Finally, we compare the relations of central and satellite galaxies, finding systematically higher metallicities for satellites, as observed. We show this is due to the removal of the metal poor gas reservoir that normally surrounds galaxies and acts to dilute their gas-phase metallicity (via cooling/accretion onto the disk), but is lost due to ram pressure stripping for satellites.

description: Abstract Background "Activity space" has been used to examine how people's habitual movements interact with their environment, and can be used to examine accessibility to healthcare opportunities. Traditionally, the standard deviational ellipse (SDE), a Euclidean measure, has been used to represent activity space. We describe the construction and application of the SDE at one and two standard deviations, and three additional network-based measures of activity space using common tools in GIS: the road network buffer (RNB), the 30-minute standard travel time polygon (STT), and the relative travel time polygon (RTT). We compare the theoretical and methodological assumptions of each measure, and evaluate the measures by examining access to primary care services, using data from western North Carolina. Results Individual accessibility is defined as the availability of healthcare opportunities within that individual's activity space. Access is influenced by the shape and area of an individual's activity space, the spatial distribution of opportunities, and by the spatial structures that constrain and direct movement through space; the shape and area of the activity space is partly a product of how it is conceptualized and measured. Network-derived measures improve upon the SDE by incorporating the spatial structures (roads) that channel movement. The area of the STT is primarily influenced by the location of a respondent's residence within the road network hierarchy, with residents living near primary roads having the largest activity spaces. The RNB was most descriptive of actual opportunities and can be used to examine bypassing. The area of the RTT had the strongest correlation with a healthcare destination being located inside the activity space. Conclusion The availability of geospatial technologies and data create multiple options for representing and operationalizing the construct of activity space. Each approach has its strengths and limitations, and presents a different view of accessibility. While the choice of method ultimately lies in the research question, interpretation of results must consider the interrelated issues of method, representation, and application. Triangulation aids this interpretation and provides a more complete and nuanced understanding of accessibility.

description: Bacidia primigenia Vain. (1928: 95)
 Type:— RUSSIA. Khanty-Mansiysk Autonomous Okrug: ”Sibiria occ.: Amensk”, [23–24 July acc. to Alava (1988)] 1880, E. Vainio s. n. (holotype: TUR-V 20803!).
 The type material of Bacidia primigenia was collected on sandy soil covering pine roots along Konda River, a tributary to the Irtysh River in western Siberia. The specimen is, unfortunately, not well preserved, consisting of three smaller envelopes of loamy sand, only some coherent and with observable lichen thalli. Vainio (1928) described it as (in translation) ‘closely related to Arthrorhaphis flavovirescens ’ (a synonym of A. citrinella), having black, sessile, urceolate apothecia that are hardly constricted at the base and measure 0.15–0.2(–0.4) mm across. Spores were described as narrowly fusiform, 17–28 × (2.5–)3–4 μm and with 3–5 septa. We have confirmed that Vainio’s observations were indeed correct. The apothecia are attached to a thin, pale (pale bluish according to Vainio), areolate thallus that may very well belong to a member of Baeomyces.
 Bacidia primigenia belongs, as predicted by Vainio (1928), to the genus Arthrorhaphis. Although spores are somewhat on the short side and have fewer septa than normally expected, we cannot exclude the possibility that B. primigenia is conspecific with A. grisea Th. Fr.

description: We calculate the effects of finite density and temperature of isospin asymmetric strange hadronic matter, for different strangeness fractions, on the in-medium properties of vector $\left( D^{\ast}, D_{s}^{\ast}, B^{\ast}, B_{s}^{\ast}\right)$ and axial-vector $\left( D_{1}, D_{1s}, B_{1}, B_{1s}\right)$ mesons, using chiral hadronic SU(3) model and QCD sum rules. We focus on the evaluation of in-medium mass-shift and shift in decay constant of above vector and axial-vector mesons. In QCD sum rule approach, the properties, e.g., the masses and decay constants of vector and axial-vector mesons are written in terms of quark and gluon condensates. These quark and gluon condensates are evaluated in the present work within chiral SU(3) model, through the medium modification of, scalar-isoscalar fields $σ$ and $ζ$, the scalar-isovector field $δ$ and scalar dilaton field $χ$, in the strange hadronic medium which includes both nucleons as well as hyperons. As we shall see in detail, the masses and decay constants of heavy vector and axial-vector mesons are affected significantly due to isospin asymmetry and strangeness fraction of the medium and these modifications may influence the experimental observables produced in heavy ion collision experiments. The results of present investigations of in-medium properties of vector and axial-vector mesons at finite density and temperature of strange hadronic medium may be helpful for understanding the experimental data from heavy-ion collision experiments in-particular for the Compressed Baryonic Matter (CBM) experiment of FAIR facility at GSI, Germany.

ARTEMIS stabilizes the genome and modulates proliferative responses in multipotent mesenchymal cells
Creators: name: Tompkins, Kathleen
Publisher: name: BioMed Central Ltd
Year: 2010

description: Abstract Background Unrepaired DNA double-stranded breaks (DSBs) cause chromosomal rearrangements, loss of genetic information, neoplastic transformation or cell death. The nonhomologous end joining (NHEJ) pathway, catalyzing sequence-independent direct rejoining of DSBs, is a crucial mechanism for repairing both stochastically occurring and developmentally programmed DSBs. In lymphocytes, NHEJ is critical for both development and genome stability. NHEJ defects lead to severe combined immunodeficiency (SCID) and lymphoid cancer predisposition in both mice and humans. While NHEJ has been thoroughly investigated in lymphocytes, the importance of NHEJ in other cell types, especially with regard to tumor suppression, is less well documented. We previously reported evidence that the NHEJ pathway functions to suppress a range of nonlymphoid tumor types, including various classes of sarcomas, by unknown mechanisms. Results Here we investigate roles for the NHEJ factor ARTEMIS in multipotent mesenchymal stem/progenitor cells (MSCs), as putative sarcomagenic cells of origin. We demonstrate a key role for ARTEMIS in sarcoma suppression in a sensitized mouse tumor model. In this context, we found that ARTEMIS deficiency led to chromosomal damage but, paradoxically, enhanced resistance and proliferative potential in primary MSCs subjected to various stresses. Gene expression analysis revealed abnormally regulated stress response, cell proliferation, and signal transduction pathways in ARTEMIS-defective MSCs. Finally, we identified candidate regulatory genes that may, in part, mediate a stress-resistant, hyperproliferative phenotype in preneoplastic ARTEMIS-deficient MSCs. Conclusions Our discoveries suggest that Art prevents genome damage and restrains proliferation in MSCs exposed to various stress stimuli. We propose that deficiency leads to a preneoplastic state in primary MSCs and is associated with aberrant proliferative control and cellular stress resistance. Thus, our data reveal surprising new roles for ARTEMIS and the NHEJ pathway in normal MSC function and fitness relevant to tumor suppression in mesenchymal tissues.

description: Abstract Background In Uganda, over half of under-five child mortality is attributed to three infectious diseases: malaria, pneumonia and diarrhoea. Integrated community case management (iCCM) trains village health workers (VHWs) to provide in-home diagnosis and treatment of these common childhood illnesses. For severely ill children, iCCM relies on a functioning referral system to ensure timely treatment at a health facility. However, referral completion rates vary widely among iCCM programmes and are difficult to monitor. The Bugoye Integrated Community Case Management Initiative (BIMI) is an iCCM programme operating in Bugoye sub-county, Uganda. This case study describes BIMI’s experience with monitoring referral completion at Bugoye Health Centre III (BHC), and outlines improvements to be made within iCCM referral systems. Methods This study triangulated multiple data sources to evaluate the strengths and gaps in the BIMI referral system. Three quantitative data sources were reviewed: (1) VHW report of referred patients, (2) referral forms found at BHC, and (3) BHC patient records. These data sources were collated and triangulated from January–December 2014. The goal was to determine if patients were completing their referrals and if referrals were adequately documented using routine data sources. Results From January–December 2014, there were 268 patients referred to BHC, as documented by VHWs. However, only 52 of these patients had referral forms stored at BHC. Of the 52 referral forms found, 22 of these patients were also found in BHC register books recorded by clinic staff. Thus, the study found a mismatch between VHW reports of patient referrals and the referral visits documented at BHC. This discrepancy may indicate several gaps: (1) referred patients may not be completing their referral, (2) referral forms may be getting lost at BHC, and, (3) referred patients may be going to other health facilities or drug shops, rather than BHC, for their referral. Conclusions This study demonstrates the challenges of effectively monitoring iCCM referral completion, given identified limitations such as discordant data sources, incomplete record keeping and lack of unique identifiers. There is a need to innovate and improve the ways by which referral compliance is monitored using routine data, in order to improve the percentage of referrals completed. Through research and field experience, this study proposes programmatic and technological solutions to rectify these gaps within iCCM programmes facing similar challenges. With improved monitoring, VHWs will be empowered to increase referral completion, allowing critically ill children to access needed health services.

description: We discuss production of $D^0 D^0$ (and ${\bar D}^0 {\bar D}^0$) pairs related to the LHCb Collaboration results for $\sqrt{s}$ = 7 TeV in proton-proton scattering. We consider double-parton scattering (DPS) mechanisms of double $c \bar c$ production and subsequent $cc \to D^{0}D^{0}$ hadronization as well as double $g$ and mixed $g c\bar c $ production with $gg \to D^{0}D^{0}$ and $gc \to D^{0}D^{0}$ hadronization calculated with the help of the scale-dependent hadronization functions of Kniehl et al. Single-parton scattering (SPS) mechanism of digluon production is also taken into account. We compare our results with several correlation observables in azimuthal angle $φ_{D^{0}D^{0}}$ between $D^{0}$ mesons or in dimeson invariant mass $M_{D^{0}D^{0}}$. The inclusion of new mechanisms with $g \to D^{0}$ fragmentation leads to larger cross sections, than when including only DPS mechanism with standard scale-independent $cc \to D^{0}D^{0}$ fragmentation functions. Some consequences of the presence of the new mechanisms are discussed. In particular a larger $σ_{eff}$ is needed to describe the LHCb data. There is a signature that $σ_{eff}$ may depend on transverse momentum of $c$ quarks and/or $\bar c$ antiquarks.

Birth location preferences of mothers and fathers in rural Ghana: Implications for pregnancy, labor and birth outcomes

Year: 2015

description: Abstract Background Maternal deaths in Sub-Saharan Africa are largely preventable with health facility delivery assisted by skilled birth attendants. Examining associations of birth location preferences on pregnant women’s experiences is important to understanding delays in care seeking in the event of complications. We explored the influence of birth location preference on women’s pregnancy, labor and birth outcomes. Methods A qualitative study conducted in rural Ghana consisted of birth narratives of mothers (n = 20) who experienced pregnancy/labor complications, and fathers (n = 18) whose partners experienced such complications in their last pregnancy. All but two women in our sample delivered in a health facility due to complications. We developed narrative summaries of each interview and iteratively coded the interviews. We then analyzed the data through coding summaries and developed analytic matrices from coded transcripts. Results Birth delivery location preferences were split for mothers (home delivery–9; facility delivery–11), and fathers (home delivery–7; facility delivery–11). We identified two patterns of preferences and birth outcomes: 1) preference for homebirth that resulted in delayed care seeking and was likely associated with several cases of stillbirths and postpartum morbidities; 2) Preference for health facility birth that resulted in early care seeking, and possibly enabled women to avoid adverse effects of birth complications. Conclusion Safe pregnancy and childbirth interventions should be tailored to the birth location preferences of mothers and fathers, and should include education on the development of birth preparedness plans to access timely delivery related care. Improving access to and the quality of care at health facilities will also be crucial to facilitating use of facility-based delivery care in rural Ghana.

description: We present a new, computationally inexpensive method for the calculation of reduced density matrix dynamics for systems with a potentially large number of subsystem degrees of freedom coupled to a generic bath. The approach consists of propagation of weak-coupling Redfield-like equations for the high frequency bath degrees of freedom only, while the low frequency bath modes are dynamically arrested but statistically sampled. We examine the improvements afforded by this approximation by comparing with exact results for the spin-boson model over a wide range of parameter space. The results from the method are found to dramatically improve Redfield dynamics in highly non--Markovian regimes, at a similar computational cost. Relaxation of the mode-freezing approximation via classical (Ehrenfest) evolution of the low frequency modes results in a dynamical hybrid method. We find that this Redfield-based dynamical hybrid approach, which is computationally more expensive than bare Redfield dynamics, yields only a marginal improvement over the simpler approximation of complete mode arrest.

description: To accomplish the energy transition, new methodologies and technical solutions for the storage of renewable energies need to be developed. A fundamental challenge lies in the fact that energy production from renewable sources (wind or sun) is subject to fluctuations that do not match the daily and/or seasonal swings of energy demand. Furthermore, the safe long-term disposal of environmentally hazardous nuclear and toxic waste in geological repositories is a social responsibility. With salt caverns and porous reservoirs, the subsurface offers a great potential for the storage of energy carriers (e.g. hydrogen, synthetic methane), potential energy (compressed energy) or thermal energy. Regardless of the time scale (daily seasonal or even over periods of up to 1 million years), barrier formations like salt, clay or crystalline rock ensure the necessary integrity and safety. This session aims to connect research, technical concepts and case studies addressing the geological boundary conditions of the various storage and repository options. The range of topics involve the description and assessment of the properties of storage and barrier formations and the relevant processes that occur during the operation and post-operation/abandonment phases of storages and repositories. These include the development of exploration methods, laboratory investigations to characterise rock properties at various scales, and the modelling-based analyses and simulations of coupled thermal, hydraulic, mechanical and (geo)chemical processes. An elementary part of these efforts is the incorporation of experience gained over the past decades to validate the models and methods used, as well as the linking of different scales of magnitude.

cells in cerebellar development. Cancer & Metabolism
2013, 1:14
We recently demonstrated that developmentally
regulated aerobic glycolysis is integral to the normal
process of postnatal neurogenesis and becomes
co-opted in medulloblastoma. In our work, we concluded
that Hexokinase 2 (Hk2), which we found to
be required for Shh-induced aerobic glycolysis, was
expressed specifically by cerebellar granule neuron
progenitors (CGNPs). We observed altered migration
of CGNPs in hGFAP-cre;Hk2f/f mice and attributed
this aspect of the phenotype to premature
differentiation of CGNPs caused by loss of aerobic
glycolysis. In response to our work, LePrince draws
attention to the role of Bergmann glia in cerebellar
development.

description: We revisit the accuracy of the post-Newtonian (PN) approximation and its region of validity for quasi-circular orbits of a point particle in the Kerr spacetime, by using an analytically known highest post-Newtonian order gravitational energy flux and accurate numerical results in the black hole perturbation approach. It is found that regions of validity become larger for higher PN order results although there are several local maximums in regions of validity for relatively low-PN order results. This might imply that higher PN order calculations are also encouraged for comparable-mass binaries.

description: We present polarization observations of two Galactic plane fields centered on Galactic coordinates (l,b)=(0 deg,0 deg) and (329 deg, 0 deg) at Q- (43 GHz) and W-band (95 GHz), covering between 301 and 539 square degrees depending on frequency and field. These measurements were made with the QUIET instrument between 2008 October and 2010 December, and include a total of 1263 hours of observations. The resulting maps represent the deepest large-area Galactic polarization observations published to date at the relevant frequencies with instrumental rms noise varying between 1.8 and 2.8 uK deg, 2.3-6 times deeper than corresponding WMAP and Planck maps. The angular resolution is 27.3' and 12.8' FWHM at Q- and W-band, respectively. We find excellent agreement between the QUIET and WMAP maps over the entire fields, and no compelling evidence for significant residual instrumental systematic errors in either experiment, whereas the Planck 44 GHz map deviates from these in a manner consistent with reported systematic uncertainties for this channel. We combine QUIET and WMAP data to compute inverse-variance-weighted average maps, effectively retaining small angular scales from QUIET and large angular scales from WMAP. From these combined maps, we derive constraints on several important astrophysical quantities, including a robust detection of polarized synchrotron spectral index steepening of ~0.2 off the plane, as well as the Faraday rotation measure toward the Galactic center (RM=-4000 +/- 200 rad m^-2), all of which are consistent with previously published results. Both the raw QUIET and the co-added QUIET+WMAP maps are made publicly available together with all necessary ancillary information.

description: Abstract Background Although smoking behavior is known to affect body mass index (BMI), the potential for smoking to influence genetic associations with BMI is largely unexplored. Methods As part of the ‘Population Architecture using Genomics and Epidemiology (PAGE)’ Consortium, we investigated interaction between genetic risk factors associated with BMI and smoking for 10 single nucleotide polymorphisms (SNPs) previously identified in genome-wide association studies. We included 6 studies with a total of 56,466 subjects (16,750 African Americans (AA) and 39,716 European Americans (EA)). We assessed effect modification by testing an interaction term for each SNP and smoking (current vs. former/never) in the linear regression and by stratified analyses. Results We did not observe strong evidence for interactions and only observed two interactions with p-values <0.1: for rs6548238/TMEM18, the risk allele (C) was associated with BMI only among AA females who were former/never smokers (β = 0.018, p = 0.002), vs. current smokers (β = 0.001, p = 0.95, pinteraction = 0.10). For rs9939609/FTO, the A allele was more strongly associated with BMI among current smoker EA females (β = 0.017, p = 3.5x10-5), vs. former/never smokers (β = 0.006, p = 0.05, pinteraction = 0.08). Conclusions These analyses provide limited evidence that smoking status may modify genetic effects of previously identified genetic risk factors for BMI. Larger studies are needed to follow up our results. Clinical Trial Registration NCT00000611

Imprint of modified Einstein's gravity on white dwarfs: Unifying type Ia supernovae

description: We establish the importance of modified Einstein's gravity (MG) in white dwarfs (WDs) for the first time in the literature. We show that MG leads to significantly sub- and super-Chandrasekhar limiting mass WDs, depending on a single model parameter. However, conventional WDs on approaching Chandrasekhar's limit are expected to trigger type Ia supernovae (SNeIa), a key to unravel the evolutionary history of the universe. Nevertheless, observations of several peculiar, under- and over-luminous SNeIa argue for the limiting mass widely different from Chandrasekhar's limit. Explosions of MG induced sub- and super-Chandrasekhar limiting mass WDs explain under- and over-luminous SNeIa respectively, thus unifying these two apparently disjoint sub-classes. Our discovery questions both the global validity of Einstein's gravity and the uniqueness of Chandrasekhar's limit.

description: The production of geothermal energy requires the circulation of large volumes of thermal brines reaching up to several 100 L/s. These brines are the product of long-time water-rock interactions at a high temperature and depth leading to various water compositions. The contained ions have been used for the chemical characterization of a reservoir and are further a challenge for the power plant operator due to the possibility of uncontrolled mineral formation. The chemical analysis of the waters and the related precipitates have shown that the waters can contain critical and strategic mineral commodities at various concentrations. According to known standards of raw material extraction, these are not classic deposits due to their low concentrations. However, in consideration of the high annual volumes circulating in geothermal systems, relevant amounts of different raw materials are in theory extractable. An advantage of the geothermal brines is that the elements of interest are already dissolved in the water and do not have to be extracted from the rock first. Furthermore, a geothermal power plant provides decentralized heat and energy for further refinement of the raw materials. The implementation of a cost-effective and deployable mineral recovery in the geothermal cycle can thus improve the economics of geothermal energy and open up a new raw material market.
