description: In recent years, geoscientific data provided considerable insights into the environmental past of polar regions. Conventional coring, seafloor drilling, and terrestrial campaigns led to increasing data availability of past environmental and ice-sheet change at both poles. As these are the regions most sensitively reacting to climatic changes, reliable datasets of past variations are critical for constraining numerical models aiming at simulating future changes more robustly. We therefore invite contributions from colleagues working in marine and terrestrial settings in both polar regions on various timescales. We particularly ask for contributions that integrate field data with numerical modeling, i.e. utilize past variations as target values for calibrating numerical simulations in order to improve their predictive capabilities for future scenarios.

description: Abstract Introduction Perhaps the major challenge in developing more effective therapeutic strategies for the treatment of breast cancer patients is confronting the heterogeneity of the disease, recognizing that breast cancer is not one disease but multiple disorders with distinct underlying mechanisms. Gene-expression profiling studies have been used to dissect this complexity, and our previous studies identified a series of intrinsic subtypes of breast cancer that define distinct populations of patients with respect to survival. Additional work has also used signatures of oncogenic pathway deregulation to dissect breast cancer heterogeneity as well as to suggest therapeutic opportunities linked to pathway activation. Methods We used genomic analyses to identify relations between breast cancer subtypes, pathway deregulation, and drug sensitivity. For these studies, we use three independent breast cancer gene-expression data sets to measure an individual tumor phenotype. Correlation between pathway status and subtype are examined and linked to predictions for response to conventional chemotherapies. Results We reveal patterns of pathway activation characteristic of each molecular breast cancer subtype, including within the more aggressive subtypes in which novel therapeutic opportunities are critically needed. Whereas some oncogenic pathways have high correlations to breast cancer subtype (RAS, CTNNB1, p53, HER1), others have high variability of activity within a specific subtype (MYC, E2F3, SRC), reflecting biology independent of common clinical factors. Additionally, we combined these analyses with predictions of sensitivity to commonly used cytotoxic chemotherapies to provide additional opportunities for therapeutics specific to the intrinsic subtype that might be better aligned with the characteristics of the individual patient. Conclusions Genomic analyses can be used to dissect the heterogeneity of breast cancer. We use an integrated analysis of breast cancer that combines independent methods of genomic analyses to highlight the complexity of signaling pathways underlying different breast cancer phenotypes and to identify optimal therapeutic opportunities.

description: In this study, we will explore and review published literature on communicating pharmacogenomic test results to pediatric patients and/or their caregivers and their expectations, fears, and attitudes towards the test results. Understanding pediatric patients' and/or their caregivers' expectations, fears, and attitudes towards the pharmacogenomic test results will help us find the gaps in current communication approaches. By gaining the knowledge and understanding of the pediatric patients' and/or caregivers' expectations, fears, and attitudes toward the test result, the study aims to develop a communication strategy framework to optimize and standardize care in pediatric pharmacogenomics. Effective communication strategies for healthcare providers are warranted to set up realistic expectations for the evidence-based use of pharmacogenomic test results to empower patients to make positive health care decisions.

description: In an asymptotically flat spacetime of dimension d > 3 and with the Newtonian gravitational constant G, a spherical black hole of initial horizon radius r_h and mass M ~ r_h^{d-3}/G has a total decay time to Hawking emission of t_d ~ r_h^{d-1}/G ~ G^{2/(d-3)}M^{(d-1)/(d-3)} which grows without bound as the radius r_h and mass M are taken to infinity. However, in asymptotically anti-de Sitter spacetime with a length scale l and with absorbing boundary conditions at infinity, the total Hawking decay time does not diverge as the mass and radius go to infinity but instead remains bounded by a time of the order of l^{d-1}/G.

description: We present a simulation method to study electrolyte solutions in a dielectric slab geometry using a modified 3D Ewald summation. The method is fast and easy to implement, allowing us to rapidly resum an infinite series of image charges. In the weak coupling limit, we also develop a mean-field theory which allows us to predict the ionic distribution between the dielectric charged plates. The agreement between both approaches, theoretical and simulational, is very good, validating both methods. Examples of ionic density profiles in the strong electrostatic coupling limit are also presented. Finally, we explore the confinement of charge asymmetric electrolytes between neutral surfaces.
The Effectiveness of Animal Welfare-, Environmental-, and Health-Focused Video Appeals on Implicit and Explicit Wanting of Meat and Intentions to Reduce Meat Consumption

description: The production of meat and its consumption are associated with negative consequences for the environment, the animals raised and slaughtered for food, and the health of those who consume animal-based foods. We investigated whether video appeals that addressed these topics affected participants’ wanting of meat and intentions to reduce meat relative to a control video. Results indicated only the environmental video led to increased intentions to reduce meat relative to controls. Nevertheless, implicit wanting of meat was lower in all three experimental conditions compared to the control condition. Additionally, moral emotions and agreement with the video’s message mediated the relationships between condition and implicit wanting and intentions for the animal welfare and environment conditions. For the health condition, only agreement with the message served as a mediator. These results suggest that although animal welfare-, environmental-, and health-focused video appeals may be effective at shifting immediate desire to consume meat, environmental video appeals may be the most effective for increasing intentions to change future meat intake.

description: Abstract Background Obtaining reliable and reproducible two-color microarray gene expression data is critically important for understanding the biological significance of perturbations made on a cellular system. Microarray design, RNA preparation and labeling, hybridization conditions and data acquisition and analysis are variables difficult to simultaneously control. A useful tool for monitoring and controlling intra- and inter-experimental variation is Universal Reference RNA (URR), developed with the goal of providing hybridization signal at each microarray probe location (spot). Measuring signal at each spot as the ratio of experimental RNA to reference RNA targets, rather than relying on absolute signal intensity, decreases variability by normalizing signal output in any two-color hybridization experiment. Results Human, mouse and rat URR (UHRR, UMRR and URRR, respectively) were prepared from pools of RNA derived from individual cell lines representing different tissues. A variety of microarrays were used to determine percentage of spots hybridizing with URR and producing signal above a user defined threshold (microarray coverage). Microarray coverage was consistently greater than 80% for all arrays tested. We confirmed that individual cell lines contribute their own unique set of genes to URR, arguing for a pool of RNA from several cell lines as a better configuration for URR as opposed to a single cell line source for URR. Microarray coverage comparing two separately prepared batches each of UHRR, UMRR and URRR were highly correlated (Pearson's correlation coefficients of 0.97). Conclusion Results of this study demonstrate that large quantities of pooled RNA from individual cell lines are reproducibly prepared and possess diverse gene representation. This type of reference provides a standard for reducing variation in microarray experiments and allows more reliable comparison of gene expression data within and between experiments and laboratories.

Key attributes of patient centered medical homes associated with patient activation of diabetes patients
Creators: name: Mills, Jon C
Publisher: name: BioMed Central

description: Abstract Background Approximately 24 million Americans are living with diabetes. Patient activation among individuals with diabetes is critical to successful diabetes management. The Patient Centered Medical Home (PCMH) model holds promise for increasing patient activation in managing their health. However, what is not well understood is the extent to which individual components of the PCMH model, such as the quality of physician-patient interactions and organizational features of care, contribute to patient activation. This study’s objective is to determine the relative importance of the PCMH constructs or domains to patient activation among individuals living with diabetes. Methods This study is a cross-sectional analysis of 1253 primary care patients surveyed with type II diabetes. The dependent variable, patient activation, was assessed using the Patient Activation Measure (PAM). Independent variables included 7 PCMH domains- organizational access, integration of care, comprehensive knowledge, office staff helpfulness, communication, interpersonal treatment and trust. Ordered logistic regression was performed to determine whether each PCMH domain was independently associated with patient activation, followed by a final ordered logistic regression that included all the PCMH domains in a single adjusted model. Results Using the full adjusted model, the odds of patients reporting higher activation scores (PAM) were found to be significant in the domains that represented organizational access (OR 1.56, 95% CI 1.31–1.85) and comprehensive knowledge (OR 1.44, 95% CI 1.13–1.85). Conclusions Many practices have struggled with the challenge to develop fully functional patient-centered medical homes. In an effort to become more patient-centered, this study aimed to address what factors activated diabetic patients to adhere to diabetes management plan. Understanding these factors can help identify PCMH attributes that practices can prioritize and improve upon to assist their patients in improving health outcomes. Trial registration Study was not a clinical trial; therefore it was not registered.

description: In a pioneering paper on the role of gravity on false vacuum decay, Coleman and De Luccia showed that a strong gravitational field can stabilize the false vacuum, suppressing the formation of true vacuum bubbles. This result is obtained for the case when the energy density difference between the two vacua is small, the so called thin wall regime, but is considered of more general validity. Here we show that when this condition does not hold, however, {\it a strong gravitational field (Planckian physics) does not necessarily induce a total suppression of true vacuum bubble nucleation}. Contrary to common expectations then, gravitational physics at the Planck scale {\it does not stabilize the false vacuum}. These results are of crucial importance for the stability analysis of the electroweak vacuum and for searches of new physics beyond the Standard Model.

Frequency of HIV-testing and factors associated with multiple lifetime HIV-testing among a rural population of Zambian men
Creators: name: Stringer, Jeffrey
Publisher: name: BioMed Central
Year: 2015

description: Abstract Background Across sub-Saharan Africa, men's levels of HIV-testing remain inadequate relative to women’s. Men are less likely to access anti-retroviral therapy and experience higher levels of morbidity and mortality once initiated on treatment. More frequent HIV-testing by men at continued risk of HIV-infection is required to facilitate earlier diagnosis. This study explored the frequency of HIV-testing among a rural population of men and the factors associated with more frequent HIV-testing. Methods We conducted a secondary analysis of a population-based survey in three rural district in Zambia, from February-November, 2013. Households (N = 300) in randomly selected squares from 42 study sites, defined as a health facility and its catchment area, were invited to participate. Individuals in eligible households were invited to complete questionnaires regarding demographics and HIV-testing behaviours. Men were defined as multiple HIV-testers if they reported more than one lifetime test. Upon questionnaire completion, individuals were offered rapid home-based HIV-testing. Results Of the 2376 men, more than half (61 %) reported having ever-tested for HIV. The median number of lifetime tests was 2 (interquartile range = 1-3). Just over half (n = 834; 57 %) of ever-testers were defined as multiple-testers. Relative to never-testers, multiple-testers had higher levels of education and were more likely to report an occupation. Among the 719 men linked to a spouse, multiple-testing was higher among men whose spouse reported ever-testing (adjusted prevalence ratio = 3.02 95 % CI: 1.37-4.66). Multiple-testing was higher in study sites where anti-retroviral therapy was available at the health facility on the day of a health facility audit. Among ever-testers, education and occupation were positively associated with multiple-testing relative to reporting one lifetime HIV-test. Almost half (49 %) of ever-testers accepted the offer of home-based HIV-testing. Discussion Reported HIV-testing increased among this population of men since a 2011/12 survey. Yet, only 35 % of all men reported multiple lifetime HIV-tests. The factors associated with multiple HIV-testing were similar to factors associated with ever-testing for HIV. Men living with HIV were less likely to report multiple HIV-tests and employment and education were associated with multiple-testing. The offer of home-based HIV-testing increased the frequency of HIV-testing among men. Conclusion Although men's levels of ever-testing for HIV have increased, strategies need to increase the lifetime frequency of HIV-testing among men at continued risk of HIV-infection.
Looking for a hidden-charm pentaquark state with strangeness $S=-1$ from $Ξ^-_b$ decay into $J/ψK^- Λ$

description: Assuming that the recently observed hidden-charm pentaquark state, $P_c(4450)$, is of molecular nature as predicted in the unitary approach, we propose to study the decay of $Ξ^-_b\rightarrow J/ψK^- Λ$ to search for the strangeness counterpart of the $P_c(4450)$. There are three ingredients in the decay mechanism: the weak decay mechanism, the hadronization mechanism, and the finite state interactions in the meson-baryon system of strangeness $S=-2$ and isospin $I=1/2$ and of the $J/ψΛ$. All these have been tested extensively. As a result, we provide a genuine prediction of the differential cross section where a strangeness hidden-charm pentaquark state, the counterpart of the $P_c(4450)$, can be clearly seen. The decay rate is estimated to be of similar magnitude as the $Λ_b^0\rightarrow J/ψK^- p$ observed by the LHCb collaboration.

description: We investigate the structural and magnetic origins of the unusual ultrafast second-harmonicgeneration (SHG) response of femtosecond-laser-excited nickel oxide (NiO) previously attributed to oscillatory reorientation dynamics of the magnetic structure induced by d-d excitations. Using time-resolved x-ray diffraction from the (3/2 3/2 3/2) magnetic planes, we show that changes in the magnitude of the magnetic structure factor following ultrafast optical excitation are limited to $Δ/$ = 1.5% in the first 30 ps. An extended investigation of the ultrafast SHG response reveals a strong dependence on wavelength as well as characteristic echoes, both of which give evidence for an acoustic origin of the dynamics. We therefore propose an alternative mechanism for the SHG response based on perturbations of the nonlinear susceptibility via optically induced strain in a spatially confined medium. In this model, the two observed oscillation periods can be understood as the times required for an acoustic strain wave to traverse one coherence length of the SHG process in either the collinear or anti-collinear geometries.

Publisher: name: BioMed Central
Year: 2010

description: Abstract Background Evidence for a high degree of heritability of EEG alpha phenotypes has been demonstrated in twin and family studies in a number of populations. However, information on linkage of this phenotype to specific chromosome locations is still limited. This study's aims were to map loci linked to EEG alpha phenotypes and to determine if there was overlap with loci previously mapped for alcohol dependence in an American Indian community at high risk for substance dependence. Methods Each participant gave a blood sample and completed a structured diagnostic interview using the Semi Structured Assessment for the Genetics of Alcoholism. Bipolar EEGs were collected and spectral power determined in the alpha (7.5-12.0 Hz) frequency band for two composite scalp locations previously identified by principal components analyses (bilateral fronto-central and bilateral centro-parietal-occipital). Genotypes were determined for a panel of 791 micro-satellite polymorphisms in 410 members of multiplex families using SOLAR. Results Sixty percent of this study population had a lifetime diagnosis of alcohol dependence. Analyses of multipoint variance component LOD scores, for the EEG alpha power phenotype, revealed two loci that had a LOD score of 3.0 or above for the fronto-central scalp region on chromosomes 1 and 6. Additionally, 4 locations were identified with LOD scores above 2.0 on chromosomes 4, 11, 14, 16 for the fronto-central location and one on chromosome 2 for the centro-parietal-occipital location. Conclusion These results corroborate the importance of regions on chromosome 4 and 6 highlighted in prior segregation studies in this and other populations for alcohol dependence-related phenotypes, as well as other areas that overlap with other substance dependence phenotypes identified in previous linkage studies in other populations. These studies additionally support the construct that EEG alpha recorded from fronto-central scalp areas may represent an important endophenotype associated with alcohol and other substance dependence.

description: We characterize the astrometric distortion at the edges of thick, fully-depleted CCDs in the lab using a bench-top simulation of LSST observing. By illuminating an array of forty thousand pinholes (30mu m diameter) at the object plane of a f/1.2 optical reimager, thousands of PSFs can be imaged over a 4Kx4K pixel CCD. Each high purity silicon pixel, 10mu m square by 100mu m deep, can then be individually characterized through a series of sub-pixel dithers in the X/Y plane. The unique character [response, position, shape] of each pixel as a function of flux, wavelength, back side bias, etc. can be investigated. We measure the magnitude and onset of astrometric error at the edges of the detector as a test of the experimental setup, using a LSST prototype CCD. We show that this astrometric error at the edge is sourced from non-uniformities in the electric field lines that define pixel boundaries. This edge distortion must be corrected in order to optimize the science output of weak gravitational lensing and large scale structure measurements for the LSST.

description: The advancement of upper forest limits is driven by environmental conditions, but our current understanding overlooks the attributes of habitats and germination ability of woody species. Habitats, through plant litter, impact the competitive relation of germination and seedling growth. The aims of this study were to identify the selective effect of six litter leachates on the germination of indigenous Norway spruce (Picea abies) and nonindigenous dwarf pine (Pinus mugo) and compare the germination rates of the species. We collected plant litter and seeds from the (sub)alpine belt of the Hrubý Jeseník Mts. (the Eastern Sudetes Mts.; the Czech Republic). We evaluated the effect of plant litter leachates from alpine heathlands, wind-swept alpine grasslands, subalpine tall-herb plants, Pinus mugo scrub, subalpine Vaccinium vegetation, and Norway spruce clonal groups on germination process under standard light and temperature conditions. The germination of Norway spruce was inhibited by the litter leachate from subalpine tall-herb vegetation mainly dominated by Calamagrostis villosa, whereas that of dwarf pine was not. The other five litter leachates had no significant effect on the both. Under standard conditions, the germination time of dwarf pine is on average one day faster. These results suggest that most of the litter leachates examined may have small impacts on the germinability and germination time of Norway spruce and dwarf pine, but litter from the subalpine tall-herb vegetation can act as a filter that influences the seedling composition of the woody species.

description: Abstract
                Background
                Many bacteria and certain eukaryotes utilize multi-step His-to-Asp phosphorelays for adaptive responses to their extracellular environments. Histidine phosphotransfer (HPt) proteins function as key components of these pathways. HPt proteins are genetically diverse, but share a common tertiary fold with conserved residues near the active site. A surface-exposed glycine at the H + 4 position relative to the phosphorylatable histidine is found in a significant number of annotated HPt protein sequences. Previous reports demonstrated that substitutions at this position result in diminished phosphotransfer activity between HPt proteins and their cognate signaling partners.
                Results
                We report the analysis of partner binding interactions and phosphotransfer activity of the prototypical HPt protein Ypd1 from Saccharomyces cerevisiae using a set of H + 4 (G68) substituted proteins. Substitutions at this position with large, hydrophobic, or charged amino acids nearly abolished phospho-acceptance from the receiver domain of its upstream signaling partner, Sln1 (Sln1-R1). An in vitro binding assay indicated that G68 substitutions caused only modest decreases in affinity between Ypd1 and Sln1-R1, and these differences did not appear to be large enough to account for the observed decrease in phosphotransfer activity. The crystal structure of one of these H + 4 mutants, Ypd1-G68Q, which exhibited a diminished ability to participate in phosphotransfer, shows a similar overall structure to that of wild-type. Molecular modelling suggests that the highly conserved active site residues within the receiver domain of Sln1 must undergo rearrangement to accommodate larger H + 4 substitutions in Ypd1.
                Conclusions
                Phosphotransfer reactions require precise arrangement of active site elements to align the donor-acceptor atoms and stabilize the transition state during the reaction. Any changes likely result in an inability to form a viable transition state during phosphotransfer. Our data suggest that the high degree of evolutionary conservation of residues with small side chains at the H + 4 position in HPt proteins is required for optimal activity and that the presence of larger residues at the H + 4 position would cause alterations in the positioning of active site residues in the partner response regulator.

description: We numerically study the work distributions in a chaotic system and examine the relationship between quantum work and classical work. Our numerical results suggest that there exists a correspondence principle between quantum and classical work distributions in a chaotic system. This correspondence was proved for one-dimensional (1D) integrable systems in a recent work [Jarzynski, Quan, and Rahav, Phys. Rev. X 5, 031038 (2015)]. Our investigation further justifies the definition of quantum work via two point energy measurements.

description: Phyllostachys edulis (Poales: Poaceae) is a bamboo species with well-developed rhizomes, which play important roles in growth, resource storage and transport. However, the extent to which rhizomes are produced, accumulated and turn over annually at the stand level remains largely unknown. We studied the biomass, production and turnover rate of rhizomes and other organs (culms, branches, leaves and roots) in a bamboo stand in Japan between 2013 and 2018. We sought to answer the following questions: To what extent is the newly assimilated carbon allocated to rhizomes, and how rapid is carbon turnover in rhizomes? How does biomass allocation to below-ground parts in bamboo ramets compare to that in woody plant individuals of similar size? We found the amount of newly produced rhizomes was 0.90 Mg C ha–1 year−1, which accounted for 9.5% of total new biomass. The carbon turnover rate of rhizomes was 0.11 g g−1 year−1, which was slower than that of other organs (i.e. longer lifespan). Compared to other woody plants of similar biomass, bamboo had 2.0-fold higher biomass allocation to below-ground organs due to the high biomass of rhizomes. Furthermore, bamboo allocated 8.7-fold lower biomass to leaves despite their high growth rates, perhaps due to the thin (but leathery) leaves and green stems that can photosynthesize as well. Our study highlights that the large storage capacity of below-ground rhizomes along with the efficient above-ground production system are the key growth features of P. edulis, which are likely to contribute to their success in temperate forests.
"A man's gonna do what a man wants to do": African American and Hispanic women's perceptions about heterosexual relationships: a qualitative study

description: Abstract: Background: HIV prevention efforts have given limited attention to the relational schemas and scripts of adult heterosexual women. These broader schemas and scripts of romantic and other sexual liaisons, partner selection, relationship dynamics, and power negotiations may help to better understand facilitators and barriers to HIV risk-reduction practices. Methods: We conducted exploratory qualitative interviews with 60 HIV-uninfected heterosexual African-American women from rural counties in North Carolina and Alabama, and Hispanic women from an urban county in southern Florida. Data were collected for relationship expectations; relationship experiences, and relationship power and decision-making. Interview transcripts underwent computer-assisted thematic analysis. Results: Participants had a median age of 34 years (range 18-59), 34% were married or living as married, 39% earned an annual income of $12,000 or less, 12% held less than a high school education, and 54% were employed. Among the Hispanic women, 95% were foreign born. We identified two overarching relationship themes: contradictions between relationship expectations and desires and life circumstances that negated such ideals, and relationship challenges. Within the contradictions theme, we discovered six subthemes: a good man is hard to find; sex can be currency used to secure desired outcomes; compromises and allowances for cheating, irresponsible, and disrespectful behavior; redefining dating; sex just happens; needing relationship validation. The challenges theme centered on two subthemes: uncertainties and miscommunication, and relationship power negotiation. Gender differences in relationship intentions and desires as well as communication styles, the importance of emotional and financial support, and the potential for relationships to provide disappointment were present in all subthemes. In examining HIV risk perceptions, participants largely held that risk for HIV-infection and the need to take precautions were problems of women who differed from them (i.e., abuse drugs, are promiscuous, exchange sex). Conclusion: Underlying women's relational schemas was a belief that relationship priorities differed for men and women. Consequently, expectations and allowances for partner infidelity and negligent behaviors were incorporated into their scripts. Moreover, scripts endorsed women's use of sex as currency in relationship formation and endurance, and did not emphasize HIV risk. Both couple- and gender-specific group-level interventions are needed to deconstruct (breakdown) and reconstruct (rewrite) relationship scripts.

description: We report new observations of multiple transitions of the CS molecular lines in the SgrA region of the Galactic center, at an angular resolution of 40" (=1.5 pc). The objective of this paper is to study the polar arc, which is a molecular ridge near the SgrA region, with apparent non-coplanar motions, and a velocity gradient perpendicular to the Galactic plane. With our high resolution dense-gas maps, we search for the base and the origin of the polar arc, which is expected to be embedded in the Galactic disk. We find that the polar arc is connected to a continuous structure from one of the disk ring/arm in both the spatial and velocity domains. This structure near SgrA* has high CS(J=4-3)/CS(J=2-1) ratios >1. That this structure has eluded detection in previous observations, is likely due to the combination of high excitation and low surface brightness temperature. We call this new structure the connecting ridge. We discuss the possible mechanism to form this structure and to lift the gas above the Galactic plane.

description: The arrival directions of TeV-PeV cosmic rays show weak but significant anisotropies with relative intensities at the level of one per mille. Due to the smallness of the anisotropies, quantitative studies require careful disentanglement of detector effects from the observation. We discuss an iterative maximum-likelihood reconstruction that simultaneously fits cosmic ray anisotropies and detector acceptance. The method does not rely on detector simulations and provides an optimal anisotropy reconstruction for ground-based cosmic ray observatories located in the middle latitudes. It is particularly well suited to the recovery of the dipole anisotropy, which is a crucial observable for the study of cosmic ray diffusion in our Galaxy. We also provide general analysis methods for recovering large- and small-scale anisotropies that take into account systematic effects of the observation by ground-based detectors.
