description: The diversity of microbial eukaryotes was surveyed by environmental sequencing from tropical lagoon sites of the South Pacific, collected through the American Museum of Natural History (AMNH)'s Explore21 expedition to the Solomon Islands in September 2013. The sampled lagoons presented low nutrient concentrations typical of oligotrophic waters, but contained levels of chlorophyll a, a proxy for phytoplankton biomass, characteristic of meso‐ to eutrophic waters. Two 18S rDNA hypervariable sites, the V4 and V8–V9 regions, were amplified from the total of eight lagoon samples and sequenced on the MiSeq system. After assembly, clustering at 97% similarity, and removal of singletons and chimeras, a total of 2741 (V4) and 2606 (V8–V9) operational taxonomic units (OTUs) were identified. Taxonomic annotation of these reads, including phylogeny, was based on a combination of automated pipeline and manual inspection. About 18.4% (V4) and 13.8% (V8–V9) of the OTUs could not be assigned to any of the known eukaryotic groups. Of these, we focused on OTUs that were not divergent and possessed multiple sources of evidence for their existence. Phylogenetic analyses of these sequences revealed more than ten branches that might represent new deeply‐branching lineages of microbial eukaryotes, currently without any cultured representatives or morphological information.

description: Heterotrophic prokaryotic production (BP) was studied in the western tropical South Pacific (WTSP) using the leucine technique, revealing spatial and temporal variability within the region. Integrated over the euphotic zone, BP ranged from 58 to 120 mg C m−2 d−1 within the Melanesian Archipelago, and from 31 to 50 mg C m−2 d−1 within the western subtropical gyre. The collapse of a bloom was followed during 6 days in the south of Vanuatu using a Lagrangian sampling strategy. During this period, rapid evolution was observed in the three main parameters influencing the metabolic state: BP, primary production (PP) and bacterial growth efficiency. With N2 fixation being one of the most important fluxes fueling new production, we explored relationships between BP, PP and N2 fixation rates over the WTSP. The contribution of N2 fixation rates to bacterial nitrogen demand ranged from 3 to 81 %. BP variability was better explained by the variability of N2 fixation rates than by that of PP in surface waters of the Melanesian Archipelago, which were characterized by N-depleted layers and low DIP turnover times (TDIP 100 h), deeper in the Melanesian Archipelago, or within the entire euphotic zone in the subtropical gyre. The bacterial carbon demand to gross primary production ratio ranged from 0.75 to 3.1. These values are discussed in the framework of various assumptions and conversion factors used to estimate this ratio, including the methodological errors, the daily variability of BP, the bacterial growth efficiency and one bias so far not considered: the ability for Prochlorococcus to assimilate leucine in the dark.
Environmental conditions regulating gene transfer in Rhodobacter capsulatus
Creators: name: Bernelot Moens, Rachel
Publisher: name: University of British Columbia
Year: 2013

description: Rhodobacter capsulatus is a metabolically versatile α-proteobacterium that produces a bacteriophage-like particle called the gene transfer agent (RcGTA) that is capable of mediating horizontal gene transfer. RcGTA particles transfer random 4.5 kb fragments of genomic DNA that integrate into recipient genomes by allelic replacement. This thesis addresses certain environmental conditions, in particular carbon limitation and the presence of subinhibitory concentrations of antibiotics, that influence gene transfer by RcGTA. A new transduction assay was developed to test the effects of various substances on gene transfer. Using this transduction assay, both carbon limitation and low levels of DNA gyrase inhibitors were found to increase the frequency of gene transfer, although by different mechanisms. Carbon limitation caused an increase in production and release of RcGTA. This effect was a general response to carbon limitation, and was independent of carbon source. Gyrase inhibitors, on the other hand, did not influence production or release of RcGTA and instead were thought to act on the recipient cells via DNA gyrase. GyrB overexpression constructs were made in order to confer resistance to novobiocin. The presence of these constructs negated the novobiocin-mediated increase in gene transfer. The results of this thesis suggest that certain antibiotics as well as carbon limitation affect gene transfer in R. capsulatus and may be relevant to microbial genetic exchange in natural ecosystems.

description: No abstracts are to be cited without prior reference to the author.Deepwater fisheries pose particular difficulties for management. Target species are difficult to assess with adequate levels of certainty, they are slow growing and generally vulnerable to overfishing and many of these fisheries reside outside EEZs and are, therefore, not subject to national jurisdictions. The EU project DEEPFISHMAN will develop a range of strategy options for the management of deepwater fisheries in the NE Atlantic that will take account of these factors. The primary objective of the project is to identify and develop new and more effective assessment methods, reference points, control rules and management strategies to be used in the short term. The second objective is to develop a long-term research and management framework in which additional data needs will be specified in order to fill current information gaps to achieve reliable long-term management requirements. This research effort will be supported by a range of case studies selected to reflect the characteristics of the different types of deepwater fisheries found in the NE Atlantic. In addition, two case studies outside the NE Atlantic are selected to give a wider perception of the management and monitoring of deepwater fisheries in the world. Case studies will collate, store, combine and raise data to appropriate fisheries/stocks levels. The socio-economic aspect of the fisheries and the expected impact of the management strategy options will be examined. The project outputs will aim to provide robust guidelines for deepwater fisheries management suitable for adoption within the Common Fishery policy.
Physics of non-Gaussian fields and the cosmological genus statistic

description: We report a technique to calculate the impact of distinct physical processes inducing non-Gaussianity on the cosmological density field. A natural decomposition of the cosmic genus statistic into an orthogonal polynomial sequence allows complete expression of the scale-dependent evolution of the morphology of large-scale structure, in which effects including galaxy bias, nonlinear gravitational evolution and primordial non-Gaussianity may be delineated. The relationship of this decomposition to previous methods for analysing the genus statistic is briefly considered and the following applications are made: i) the expression of certain systematics affecting topological measurements; ii) the quantification of broad deformations from Gaussianity that appear in the genus statistic as measured in the Horizon Run simulation; iii) the study of the evolution of the genus curve for simulations with primordial non-Gaussianity. These advances improve the treatment of flux-limited galaxy catalogues for use with this measurement and further the use of the genus statistic as a tool for exploring non-Gaussianity.

description: In the Koobi Fora region of the northeast Lake Turkana Basin (Kenya) dozens of archeological sites have been studied for decades in order to understand the behavior of Early Pleistocene hominins. Data collected from these sites have been important for demonstrating the manufacture styles of Oldowan stone-tool users, hominin dietary preferences, and processes of Early Stone Age site formation. A particularly rich locality is collection Area 130. Area 130 is noteworthy for hominin fossils KNM-ER 1805 (Homo) and 1806 (Paranthropus) as well as the FxJj 18 site complex, which represents one of the type localities for the Developed Oldowan of Koobi Fora. However, despite research beginning in the late 1960s, and several revisions to the stratigraphy and dating of the Koobi Fora Formation, few published studies provide a detailed chronostratigraphy for Area 130. The lack of a detailed chronostratigraphy has contributed to conflicting interpretations for the dates of the hominin fossils and archaeological sites. Here we present new geochronologic and paleomagnetic data to develop a chronostratigraphic framework that allows us to directly assess the age of the sediments, fossils, and artifacts from Area 130. Individual pumices from the Orange Tuff marker level and a previously unnamed tuff exposed near the FxJj 18 archaeological site complex (referred here as the FxJj 18 tuff) were analyzed for high-precision single crystal 40Ar/39Ar dating and dated at 1.763 ± 0.007 Ma and 1.520 ± 0.005 Ma respectively. Concurrently, we collected orientated paleomagnetic samples from stratigraphic levels of the KBS Member in Area 130 and used them to develop a magnetostratigraphic section. Our findings can be used to refine the sequence and chronology of the archaeological and fossils sites from Area 130 and other penecontemporaneous sites within the Lake Turkana Basin. Our data show that the first appearance of the Developed Oldowan for Koobi Fora does not correlate with any obvious evolutionary changes represented by the local hominin hypodigm nor with the arrival of a cognitively advanced hominin. Therefore we speculate that the advent of this more sophisticated type of stone tool was a response to a change in the diet of the genus Homo.

description: We present multi-wavelength observations of the afterglow of the short GRB111117A, and follow-up observations of its host galaxy. From rapid optical and radio observations we place limits of r \gtrsim 25.5 mag at \deltat \approx 0.55 d and F_nu(5.8 GHz) < 18 \muJy at \deltat \approx 0.50 d, respectively. However, using a Chandra observation at t~3.0 d we locate the absolute position of the X-ray afterglow to an accuracy of 0.22" (1 sigma), a factor of about 6 times better than the Swift-XRT position. This allows us to robustly identify the host galaxy and to locate the burst at a projected offset of 1.25 +/- 0.20" from the host centroid. Using optical and near-IR observations of the host galaxy we determine a photometric redshift of z=1.3 (+0.3,-0.2), one of the highest for any short GRB, and leading to a projected physical offset for the burst of 10.5 +/- 1.7 kpc, typical of previous short GRBs. At this redshift, the isotropic gamma-ray energy is E_{gamma,iso} \approx 3\times10^51 erg (rest-frame 23-2300 keV) with a peak energy of E_{pk} \approx 850-2300 keV (rest-frame). In conjunction with the isotropic X-ray energy, GRB111117A appears to follow our recently-reported E_x,iso-E_gamma,iso-E_pk universal scaling. Using the X-ray data along with the optical and radio non-detections we find that for a blastwave kinetic energy of E_{K,iso} \approx E_{gamma,iso}, the circumburst density is n_0 \sim 3x10^(-4)-1 cm^-3 (for a range of epsilon_B=0.001-0.1). Similarly, from the non-detection of a break in the X-ray light curve at t<3 d, we infer a minimum opening angle for the outflow of theta_j> 3-10 degrees (depending on the circumburst density). We conclude that Chandra observations of short GRBs are effective at determining precise positions and robust host galaxy associations in the absence of optical and radio detections.

description: Discrete-velocity approximations represent a popular way for computing the Boltzmann collision operator. The direct numerical evaluation of such methods involve a prohibitive cost, typically $O(N^{2d+1})$ where $d$ is the dimension of the velocity space. In this paper, following the ideas introduced in [27,28], we derive fast summation techniques for the evaluation of discrete-velocity schemes which permits to reduce the computational cost from $O(N^{2d+1})$ to $O(\bar{N}^d N^d\log_2 N)$, $\bar{N} << N$, with almost no loss of accuracy.

Nuclear symmetry energy and the r-mode instability of neutron stars

Subjects: subject: Nuclear Theory (nucl-th)

description: We analyze the role of the symmetry energy slope parameter $L$ on the {\it r}-mode instability of neutron stars. Our study is performed using both microscopic and phenomenological approaches of the nuclear equation of state. The microscopic ones include the Brueckner--Hartree--Fock approximation, the well known variational equation of state of Akmal, Pandharipande and Ravenhall, and a parametrization of recent Auxiliary Field Diffusion Monte Carlo calculations. For the phenomenological approaches, we use several Skyrme forces and relativisic mean field models. Our results show that the {\it r}-mode instability region is smaller for those models which give larger values of $L$. The reason is that both bulk ($ξ$) and shear ($η$) viscosities increase with $L$ and, therefore, the damping of the mode is more efficient for the models with larger $L$. We show also that the dependence of both viscosities on $L$ can be described at each density by simple power-laws of the type $ξ=A_ξL^{B_ξ}$ and $η=A_ηL^{B_η}$. Using the measured spin frequency and the estimated core temperature of the pulsar in the low-mass X-ray binary 4U 1608-52, we conclude that observational data seem to favor values of $L$ larger than $\sim 50$ MeV if this object is assumed to be outside the instability region, its radius is in the range $11.5-12$($11.5-13$) km, and its mass $1.4M_\odot$($2M_\odot$). Outside this range it is not possible to draw any conclusion on $L$ from this pulsar.

description: Albeit, the implicit feedback based recommendation problem - when only the user history is available but there are no ratings - is the most typical setting in real-world applications, it is much less researched than the explicit feedback case. State-of-the-art algorithms that are efficient on the explicit case cannot be straightforwardly transformed to the implicit case if scalability should be maintained. There are few if any implicit feedback benchmark datasets, therefore new ideas are usually experimented on explicit benchmarks. In this paper, we propose a generic context-aware implicit feedback recommender algorithm, coined iTALS. iTALS apply a fast, ALS-based tensor factorization learning method that scales linearly with the number of non-zero elements in the tensor. The method also allows us to incorporate diverse context information into the model while maintaining its computational efficiency. In particular, we present two such context-aware implementation variants of iTALS. The first incorporates seasonality and enables to distinguish user behavior in different time intervals. The other views the user history as sequential information and has the ability to recognize usage pattern typical to certain group of items, e.g. to automatically tell apart product types or categories that are typically purchased repetitively (collectibles, grocery goods) or once (household appliances). Experiments performed on three implicit datasets (two proprietary ones and an implicit variant of the Netflix dataset) show that by integrating context-aware information with our factorization framework into the state-of-the-art implicit recommender algorithm the recommendation quality improves significantly.

description: Studying toric varieties from a scheme-theoretical point of view leads to toric schemes, i.e. "toric varieties over arbitrary base rings". It is shown how the base ring affects the geometry of a toric scheme. Moreover, generalisations of results by Cox and Mustata allow to describe quasicoherent sheaves on toric schemes in terms of graded modules. Finally, a toric version of the Serre-Grothendieck correspondence relates cohomology of quasicoherent sheaves on toric schemes to local cohomology of graded modules.

description: Temporal variability in dissolved inorganic, organic phosphate (Pi, DOP) and particulate phosphorus (PPO4) concentrations, and microbial utilization of Pi and dissolved adenosine-5′-triphosphate (DATP) was studied at Station ALOHA (22.75◦N, 158◦W) in the North Pacific Subtropical Gyre (NPSG) over a multi-year period. Spatial variability of the same properties was investigated along two transects, to and from Hawaii, that traversed the NPSG boundaries to the east (2014) and north (2016). Radiotracer techniques were employed to measure the turnover time of Pi and DATP pools to calculate Pi uptake rates and the Pi hydrolysis rates of DATP. Pi concentrations were more variable, both in time and space, than DOP, ranging two orders of magnitude compared to a factor of two for DOP. The DATP pool, while constituting on average <0.15% of the total DOP-P, was as dynamic as Pi (∼1–200 pmol l−1), with lowest concentrations coinciding with Pi depletion. The Pi turnover times ranged from a few hours to several weeks, and were correlated with measured Pi concentrations (r = 0.9; Station ALOHA, n = 28; 2014, n = 14; 2016, n = 12). Pi uptake rates averaged 3.6 ± 1.3 nmol-P l−1 d−1 (n = 28: Station ALOHA), 9.2 ± 4.7 nmol-P l−1 d−1, (n = 15; 2014) and 5.1 ± 2.5 nmol-P l−1 d−1, (n = 12; 2016). The turnover time of the DATP pool was typically substantially shorter (0.4–5 days) than for the Pi-pool, and uptake rates ranged from 1 to 115 pmol l−1 d−1. However, at very low Pi and ATP concentrations, ATP turnover was longer than Pi turnover and ATP uptake rates lower. Total ATP hydrolysis was high along both transects, exceeding the ATP taken up by the microbial community, resulting in a net release of Pi into the ambient seawater. This net release was positively correlated to Pi concentration. The relative contribution by microbial size classes to total P-uptake depended on whether P was derived from ambient Pi or from DATP, with the <0.6>0.2 μm size class dominating the DATP uptake. Our results indicate that during Pi limiting conditions, regenerated P is rapidly consumed, and that Pi limitation occurs locally and transiently but does not appear to be the predominant condition in the upper water column of the NPSG.

Magnetic Scaling Laws for the Atmospheres of Hot Giant Exoplanets
Creators: name: Menou, Kristen
Publisher: name: arXiv
Year: 2011
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: We present scaling laws for advection, radiation, magnetic drag and ohmic dissipation in the atmospheres of hot giant exoplanets. In the limit of weak thermal ionization, ohmic dissipation increases with the planetary equilibrium temperature (T_eq >~ 1000 K) faster than the insolation power does, eventually reaching values >~ 1% of the insolation power, which may be sufficient to inflate the radii of hot Jupiters. At higher T_eq values still, magnetic drag rapidly brakes the atmospheric winds, which reduces the associated ohmic dissipation power. For example, for a planetary field strength B=10G, the fiducial scaling laws indicate that ohmic dissipation exceeds 1% of the insolation power over the equilibrium temperature range T_eq ~ 1300-2000 K, with a peak contribution at T_eq ~ 1600 K. Evidence for magnetically dragged winds at the planetary thermal photosphere could emerge in the form of reduced longitudinal offsets for the dayside infrared hotspot. This suggests the possibility of an anticorrelation between the amount of hotspot offset and the degree of radius inflation, linking the atmospheric and interior properties of hot giant exoplanets in an observationally testable way. While providing a useful framework to explore the magnetic scenario, the scaling laws also reveal strong parameter dependencies, in particular with respect to the unknown planetary magnetic field strength.

description: The western tropical South Pacific (WTSP) Ocean has been recognized as a global hot spot of dinitrogen (N₂) fixation. Here, as in other marine environments across the oceans, N₂ fixation studies have focused on the sunlit layer. However, studies have confirmed the importance of aphotic N₂ fixation activity, although until now only one had been performed in the WTSP. In order to increase our knowledge of aphotic N₂ fixation in the WTSP, we measured N₂ fixation rates and identified diazotrophic phylotypes in the mesopelagic layer along a transect spanning from New Caledonia to French Polynesia. Because non-cyanobacterial diazotrophs presumably need external dissolved organic matter (DOM) sources for their nutrition, we also identified DOM compounds using Fourier transform ion cyclotron resonance mass spectrometry (FTICRMS) with the aim of searching for relationships between the composition of DOM and non-cyanobacterial N₂ fixation in the aphotic ocean. N₂ fixation rates were low (average 0.63 ± 0.07 nmol N L⁻¹ d⁻¹) but consistently detected across all depths and stations, representing ∼ 6–88 % of photic N₂ fixation. N₂ fixation rates were not significantly correlated with DOM compounds. The analysis of nifH gene amplicons revealed a wide diversity of non-cyanobacterial diazotrophs, mostly matching clusters 1 and 3. Interestingly, a distinct phylotype from the major nifH subcluster 1G dominated at 650 dbar, coinciding with the oxygenated Subantarctic Mode Water (SAMW). This consistent pattern suggests that the distribution of aphotic diazotroph communities is to some extent controlled by water mass structure. While the data available are still too scarce to elucidate the distribution and controls of mesopelagic non-cyanobacterial diazotrophs in the WTSP, their prevalence in the mesopelagic layer and the consistent detection of active N₂ fixation activity at all depths sampled during our study suggest that aphotic N₂ fixation may contribute significantly to fixed nitrogen inputs in this area and/or areas downstream of water mass circulation.

description: A study of the formation of excitons as a problem of two Dirac particles confined in two-layer graphene sheets separated by a dielectric when gaps are opened and they interact via a Coulomb potential is presented. We propose to observe Bose-Einstein condensation and superfluidity of quasi-two-dimensional dipole excitons in double layer graphene in the presence of band gaps. The energy spectrum of the collective excitations, the sound spectrum, and the effective exciton mass are functions of the energy gaps, density and interlayer separation. The superfluid density ns and temperature of the Kosterlitz-Thouless phase transition Tc are decreasing functions of the energy gaps as well as the interlayer separation, and therefore, could be controlled by these parameters.

description: Drawing on conversation analysis (CA), this study examines reported thought (e.g., “you’re like ‘do I really have to do that?’”) and its function in writing center talk. Previous related studies, which are informed by Goffman’s (1981) notion of footing, have demonstrated how reported thought (RT) is a resource for modeling undesirable reactions and conveying criticisms in instructional interaction (Park, 2018; Sandlund, 2014). Extending this previous research on RT, I show how tutorial participants also produce RT to accomplish two kinds of supportive action: (1) praising drafts and (2) affiliating with interlocutors’ stances. With RT, tutors can “depersonalize” (Waring, 2017, p. 26) their positive assessments of writers’ drafts and demonstrate sympathetic understanding of writers’ complaints. In line with recent research (Baffy, 2018; Brown, 2010), this analysis offers additional evidence that RT is integral for socialization, or conveying and reinforcing key practices, processes, and values in academic writing and reading. To conclude, I consider how future work on RT in writing center talk, specifically on its utility for representing and constructing audiences, might inform teaching pedagogy and future research.

description: In this paper we elaborate on earlier work by the same authors in which a novel Bayesian inference framework for testing the strong-field dynamics of General Relativity using coalescing compact binaries was proposed. Unlike methods that were used previously, our technique addresses the question whether one or more 'testing coefficients' (e.g. in the phase) parameterizing deviations from GR are non-zero, rather than all of them differing from zero at the same time. The framework is well-adapted to a scenario where most sources have low signal-to-noise ratio, and information from multiple sources as seen in multiple detectors can readily be combined. In our previous work, we conjectured that this framework can detect generic deviations from GR that can in principle not be accomodated by our model waveforms, on condition that the change in phase near frequencies where the detectors are the most sensitive is comparable to that induced by simple shifts in the lower-order phase coefficients of more than a few percent ($\sim 5$ radians at 150 Hz). To further support this claim, we perform additional numerical experiments in Gaussian and stationary noise according to the expected Advanced LIGO/Virgo noise curves, and coherently injecting signals into the network whose phasing differs structurally from the predictions of GR, but with the magnitude of the deviation still being small. We find that even then, a violation of GR can be established with good confidence.

description: The evaluation use literature agrees that there is a set of consequences that result from involvement in the evaluation, namely use of process and findings. Recently, research is focusing more on the relationships between use of findings and process. The relationship between process and findings use has been examined in relation to involvement in the evaluation process. Empirical research shows that involvement plays a large role in enhancing use of findings and process, and the effects of process use on the use of evaluation findings. The purpose of this study is to examine the relationship among process use, use of findings, and stakeholder involvement in an evaluation and the effects of factors identified in the literature on use. The study considers use in the context of the evaluation of the “Working on Walls” (WOW) project. Through a Delphi technique with three rounds, perceptions of the ongoing evaluation of the project were elicited from WOW participants. This research investigated process and findings use individually and the relationship between them and it provides an example of using the Delphi method in evaluation research. The Delphi technique that was used had many limitations in this context. The most important were attrition rate, biased results, and misinformed participants. The Delphi survey results provided an accurate but incomplete view of the factors that were available in the evaluation. However, it failed to correctly identify uses of the evaluation. Although this study had some limitations, it provides an example that emphasizes the importance of the personal factor on process and findings use of an evaluation. It also emphasizes the importance of decision-makers’ attitudes towards evaluation on stakeholder’s perceptions of an evaluation. Lastly, the survey created for this study is one of a kind that can be useful for future research on evaluation use.

description: No abstracts are to be cited without prior reference to the author.There are basically two ways that fishery data are collected: by conducting a complete census or by using (it is hoped) a sound of statistical sampling program. It is is clear how a census can produce biased results. For example, fishers not reporting honestly the amount of fish caught during a trip. By contrast, bias inherent in non-census data collection program will be difficult or impossible to detect if the sampling programs is not based on a sound survey design, for example, if it employs an ad hoc sampling scheme.

description: Oligotrophic regions play a central role in global biogeochemical cycles, with microbial communities in these areas representing an important term in global carbon budgets. While the general structure of microbial communities has been well documented in the global ocean, some remote regions such as the western tropical South Pacific (WTSP) remain fundamentally unexplored. Moreover, the biotic and abiotic factors constraining microbial abundances and distribution remain not well resolved. In this study, we quantified the spatial (vertical and horizontal) distribution of major microbial plankton groups along a transect through the WTSP during the austral summer of 2015, capturing important autotrophic and heterotrophic assemblages including cytometrically determined abundances of non-pigmented protists (also called flagellates). Using environmental parameters (e.g., nutrients and light availability) as well as statistical analyses, we estimated the role of bottom–up and top–down controls in constraining the structure of the WTSP microbial communities in biogeochemically distinct regions. At the most general level, we found a “typical tropical structure”, characterized by a shallow mixed layer, a clear deep chlorophyll maximum at all sampling sites, and a deep nitracline. Prochlorococcus was especially abundant along the transect, accounting for 68 ± 10.6 % of depth-integrated phytoplankton biomass. Despite their relatively low abundances, picophytoeukaryotes (PPE) accounted for up to 26 ± 11.6 % of depth-integrated phytoplankton biomass, while Synechococcus accounted for only 6 ± 6.9 %. Our results show that the microbial community structure of the WTSP is typical of highly stratified regions, and underline the significant contribution to total biomass by PPE populations. Strong relationships between N2 fixation rates and plankton abundances demonstrate the central role of N2 fixation in regulating ecosystem processes in the WTSP, while comparative analyses of abundance data suggest microbial community structure to be increasingly regulated by bottom–up processes under nutrient limitation, possibly in response to shifts in abundances of high nucleic acid bacteria (HNA).

description: Diabetes is a disease with high prevalence in the United States with negative consequences on both health and productivity. Type 2 diabetes (T2D) accounts for roughly 90% of diabetes cases in the country and disproportionately affects those identifying as either Black or Hispanic and those of high socioeconomic deprivation (SED). The NIH All of Us program, which has developed a diverse population biobank, provides rich opportunities to study how racial identity, genetic ancestry, and SED interact to affect T2D risk. Data from the program was used to construct the study cohort. Numerical metrics at the level of the individual (iSDI) and zip code (zSDI) were used to quantify SED. The All of Us Researcher Workbench was used to calculate T2D prevalence estimates and to model T2D risk as a function of varying combinations of self-identified race and ethnicity (SIRE), genetic ancestry, iSDI, and zSDI. The study cohort spans 86,488 participants from the four largest SIRE groups in All of Us: Asian (n=2311), Black (n=16,282), Hispanic (n=16,966), and White (n=50,292). The Black and Hispanic SIRE groups have the highest T2D prevalence estimates and the highest average SED based on zSDI. Consistent with prior studies, SED was found to be generally associated with T2D risk. However, higher SED was associated with lower T2D risk within the Black and Hispanic subgroups, running contrary to a similar study we conducted using data from the U.K. Biobank, where membership to a minority group interacted with SED to amplify T2D risk. These findings may be indicative of the effects of the healthy immigrant effect or limitations of the zSDI metric. Furthermore, the contribution of membership to the Black and Hispanic SIRE groups to T2D risk is reduced when controlling for SED, suggesting that SED drives T2D disparities.

description: We investigate whether or not perturbative unitarity is preserved in the Unhiggs model for the scattering process of heavy quarks and longitudinal gauge bosons $\bar q q \to V_L^+ V_L^-$. With the Yukawa coupling given in the original formulation of the Unhiggs model, the model preserves unitarity for Unhiggs scaling dimensions $d\leq 1.5$. We examine the LHC phenomenology that is implied by the Unhiggs model in this parameter range in detail and discuss to what extent the LHC can test $d$ if an excess is measured in the phenomenologically clean $ZZ$ channel in the future or if the LHC measurement remains consistent with the background. We then make use of the AdS/CFT correspondence to derive a new Yukawa coupling that is conformally invariant at high energies, and show that with this Yukawa coupling the theory is unitary for $1 \leq d < 2$.

description: In this paper, we explore the TGTG formula from the perspective of mode summation approach. Both scalar fields and electromagnetic fields are considered. In this approach, one has to first solve the equation of motion to find a wave basis for each object. The two T's in the TGTG formula are T-matrices representing the Lippmann-Schwinger T-operators, one for each of the objects. The two G's in the TGTG formula are the translation matrices, relating the wave basis of an object to the wave basis of the other object. After discussing the general theory, we apply the prescription to derive the explicit formulas for the Casimir energies for the sphere-sphere, sphere-plane, cylinder-cylinder and cylinder-plane interactions. First the T-matrices for a plane, a sphere and a cylinder are derived for the following cases: the object is imposed with general Robin boundary conditions; the object is semitransparent; and the object is magnetodielectric. Then the operator approach is used to derive the translation matrices. From these, the explicit TGTG formula for each of the scenarios can be written down. Besides summarizing all the TGTG formulas that have been derived so far, we also provide the TGTG formulas for some scenarios that have not been considered before.
