description: We discuss a sample of 29 AGN (16 narrow-lined and 13 broad-lined) discovered in a spectroscopic survey of ~1000 star-forming Lyman-break galaxies (LBGs) at z~3. Reaching apparent magnitudes of R_{AB}=25.5, the sample includes broad-lined AGN approximately 100 times less UV-luminous than most surveys to date covering similar redshifts, and the first statistical sample of UV/optically-selected narrow-lined AGN at high redshift. The fraction of objects in our survey with clear evidence for AGN activity is ~3%. A substantial fraction, perhaps even most, of these objects would not have been detected in even the deepest existing X-ray surveys. We argue that these AGN are plausibly hosted by the equivalent of LBGs. The UV luminosities of the broad-lined AGN in the sample are compatible with Eddington-limited accretion onto black holes that satisfy the locally determined M_{BH} versus M_{bulge} relation given estimates of the stellar masses of LBGs. The clustering properties of the AGN are compatible with their being hosted by objects similar to LBGs. The implied lifetime of the active AGN phase in LBGs, if it occurs some time during the active star-formation phase, is ~10^7 years.

description: This research work, evaluates the effectiveness of liquid fertilizer produced from banana peels on soil nourishment of a phosphate-deficient corn leave. Thus, liquid fertilizer produced from banana peels through extraction by submersion for immersion was applied to soil habituating corn leave cultivation, identified to be deficient in phosphate nutrients, to evaluate the effectiveness of the solution in providing required mineral nutrients for the remediation of the soil environment used by plants. It was found that the corn leaves responded to the application of the fertilizer produced within three to four weeks, signifying the positive effect on recovery upon intake of phosphorus nutrients

description: The power spectrum of redshifted 21 cm emission brightness temperature fluctuations is a powerful probe of the Epoch of Reionization (EoR). However, bright foreground emission presents a significant impediment to its unbiased recovery from interferometric data. We build on the Bayesian power spectral estimation methodology introduced in Sims et al. 2016 and demonstrate that incorporating a priori knowledge of the spectral structure of foregrounds in the large spectral scale component of the data model enables significantly improved modelling of the foregrounds without increasing the model complexity. We explore two astrophysically motivated parametrisations of the large spectral scale model: (i) a constant plus power law model of the form $q_{0}+q_{1}(ν/ν_{0})^{b_{1}}$ for two values of $b_{1}$: $b_{1} = _\mathrm{GDSE}$ and $b_{1} = _\mathrm{EGS}$, the mean spectral indices of the Galactic diffuse synchrotron emission and extragalactic source foreground emission, respectively, and (ii) a constant plus double power law model of the form $q_{0}+q_{1}(ν/ν_{0})^{b_{1}}+q_{2}(ν/ν_{0})^{b_{2}}$ with $b_{1} = _\mathrm{GDSE}$ and $b_{2} = _\mathrm{EGS}$. We estimate the EoR power spectrum from simulated interferometric data consisting of an EoR signal, Galactic diffuse synchrotron emission, extragalactic sources and diffuse free-free emission from the Galaxy. We show that, by jointly estimating a model of the EoR signal with the constant plus double power law parametrisation of the large spectral scale model, unbiased estimates of the EoR power spectrum are recoverable on all spatial scales accessible in the data set, including on the large spatial scales that were found to be contaminated in earlier work.

description: The zeta-function regularization method is used to evaluate the renormalized effective action for massless conformally coupling scalar field propagating in a closed Friedman spacetime perturbed by a small rotation. To the second order of the rotational parameter in the model spacetime the analytic form of the effective action is obtained with the help of the Schwinger perturbation formula. After investigating the time evolution of the rotational parameter we find that the quantum field effect can produce an effect which damps the cosmological rotational in the early universe.

description: Examinations of stormwater delivery in the context of tidal inundation are lacking. Along the coastal plains of the southeastern United States, tidal inundation is increasing in frequency and severity, often with dramatic adverse impacts on timely stormwater discharge, coastal flooding hazards, and even “sunny day flooding”. Therefore, a comprehensive study was conducted to examine tidally-influenced stormwater outfalls discharging to Taylor's Creek, an estuary proximal to Beaufort, NC used regularly for recreation and tourism. Over a wide range of meteorological conditions, water samples were collected and analyzed for fecal indicator bacteria (FIB, used for water quality management) and previously published quantitative microbial source tracking (qMST) markers. Nineteen sampling events were conducted from July 2017–June 2018 with samples classified according to tidal state and defined as either inundated, receding, or transition. A first-of-its-kind multiple linear regression model was developed to predict concentrations of Enterococcus sp. by tidal cycle, salinity and antecedent rainfall. We demonstrated that the majority of variability associated with the concentration of Enterococcus sp. could be predicted by E. coli concentration and tidal phase. FIB concentrations were significantly (<0.05) influenced by tide with higher concentrations observed in samples collected during receding (low) tides (EC: log 3.12 MPN/100 mL; ENT: 2.67 MPN/100 mL) compared to those collected during inundated (high) (EC: log 2.62 MPN/100 mL; ENT: 2.11 MPN/100 mL) or transition (EC: log 2.74 MPN/100 mL; ENT: 2.53 MPN/100 mL) tidal periods. Salinity, was also found to significantly (<0.05) correlate with Enterococcus sp. concentrations during inundated (high) tidal conditions (sal: 17 ppt; ENT: 2.04 MPN/100 mL). Tide, not precipitation, was shown to be a significant driver in explaining the variability in Enterococcus sp. concentrations. Precipitation has previously been shown to be a driver of Enterococcus sp. concentrations, but our project demonstrates the need for tidal parameters to be included in the future development of water quality monitoring programs.

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The aim of this work is to find a simple mathematical framework for our established description of particle physics. We demonstrate that the particular gauge structure, group representations and charge assignments of the Standard Model particles are all captured by the algebra M(8,$\mathbb{C})$ of complex 8$\times$8 matrices. This algebra is well motivated by its close relation to the normed division algebra of octonions. (Anti-)particle states are identified with basis elements of the vector space M(8,$\mathbb{C})$. Gauge transformations are simply described by the algebra acting on itself. Our result shows that all particles and gauge structures of the Standard Model are contained in the tensor product of all four normed division algebras, with the quaternions providing the Lorentz representations. Interestingly, the space M(8,$\mathbb{C})$ contains two additional elements independent of the Standard Model particles, hinting at a minimal amount of new physics.

The two modes $a$ and $b$ are the signal and image band modes of an heterodyne detector, with the field approaching an eigenstate of the photocurrent $\hat{Z}=a+b^†$. The field is obtained by means of a high-gain phase-insensitive amplifier followed by a high-transmissivity beam-splitter with a strong local oscillator at the frequency of one of the two modes.

A Constraint on the Gravitational Lensing Magnification and Age of the Redshift z=6.28 Quasar SDSS 1030+0524

description: The recent discovery of bright quasars around redshift z=6 suggests that black holes (BHs) with masses in excess of 10^9 Msun have already assembled at a very early stage in the evolution of the universe. An alternative interpretation is that these quasars are powered by less massive BHs, but their fluxes are strongly magnified through gravitational lensing by intervening galaxies. Here we analyze the flux distribution of the Ly alpha emission of the quasar with the highest known redshift, SDSS 1030+0524, at z=6.28. We show that this object could not have been magnified by lensing by more than a factor of five. The constraint arises from the large observed size, 30 (comoving) Mpc, of the ionized region around this quasar, and relies crucially only on the assumption that the quasar is embedded in a largely neutral IGM. Based on the line/continuum ratio of SDSS 1030+0524, we argue further that this quasar also cannot be beamed by a significant factor. We conclude that the minimum mass for its resident BH is 4 x 10^8 Msun (for magnification by a factor of five); if the mass is this low, then the quasars had to switch on prior to redshift z=9. From the size of the ionized region, we are also able to place an absolute lower bound on the age of this quasar at t > 2 x 10^7 years.

description: Beenakker noticed that the peculiar band structure of Dirac fermions in 2D solids allows for the specular Andreev reflection in these systems which has no analogue in other 2D electron systems. An interesting deformation of the Dirac equation in the solid state is to tilt it which has now materials realization. In this work we report another peculiar feature of the Andreev reflection in tilted 2D Dirac cone systems. The tilt deformation of the Dirac equation is characterized by two parameters ${\boldsymbolζ}=ζ(\cosθ,\sinθ)$. We show that when the tilt parameter is tuned to its "horizon value" $ζ=1$, irrespective of the incidence angle of electrons, the Andreev reflected hole is always reflected {\em perpendicular} to the interface. Furthermore at the horizon value, if the tilt direction is perpendicular to the interface, the conductance will be energy independent for the entire sub gap energies. For generic tilt $\boldsymbolζ$, the tilt dependence of the conductance line shape can be used to extract information about the direction and magnitude of the tilt.

R-modes of neutron stars with the superfluid core

description: We investigate the modal properties of the $r$-modes of rotating neutron stars with the core filled with neutron and proton superfluids, taking account of entrainment effects between the superfluids. The stability of the $r$-modes against gravitational radiation reaction is also examined considering viscous dissipation due to shear and a damping mechanism called mutual friction between the superfluids in the core. We find the $r$-modes in the superfluid core are split into ordinary $r$-modes and superfluid $r$-modes, which we call, respectively, $r^o$- and $r^s$-modes. The two superfluids in the core flow together for the $r^o$-modes, while they counter-move for the $r^s$-modes. For the $r^o$-modes, the coefficient $κ_0\equiv\lim_{Ω\to 0}ω/Ω$ is equal to $2m/[l^\prime(l^\prime+1)]$, almost independent of the parameter $η$ that parameterizes the entrainment effects between the superfluids, where $Ω$ is the angular frequency of rotation, $ω$ the oscillation frequency observed in the corotating frame of the star, and $l^\prime$ and $m$ are the indices of the spherical harmonic function representing the angular dependence of the $r$-modes. For the $r^s$-modes, on the other hand, $κ_0$ is equal to $2m/[l^\prime(l^\prime+1)]$ at $η=0$ (no entrainment), and it almost linearly increases as $η$ is increased from $η=0$. The mutual friction in the superfluid core is found ineffective to stabilize the $r$-mode instability caused by the $r^o$-mode except in a few narrow regions of $η$. The $r$-mode instability caused by the $r^s$-modes, on the other hand, is extremely weak and easily damped by dissipative processes in the star.

description: This paper analyzes comovements and connectedness of commodity futures in the past two decades. We apply dynamic conditional correlation model (DCC) to capture time-varying dependence structure of a variety of commodities across different sectors. We propose to estimate network connectedness of commodity markets by the modeling framework of Diebold and Yilmaz (2014) that studies direction and magnitude of volatility spillover using reduced-form vector autoregression (VAR) models and generalized forecast error variance decomposition. We find that both DCC and VAR models present consistent results: while comovements and connectedness of commodity markets have dramatically increased during 2007-2009 financial distress, they have returned to the pre-crisis levels after. We also find that recent downward movement of commodity prices does not necessarily indicate stronger connection between commodity markets, which poses challenges on recent studies in commodity financialization.

description: Polarity fields are known to exhibit long distance patterns, in both physical and biological systems. The mechanisms behind such patterns are poorly understood. Here, we describe the dynamics of polarity fields using an original physical model that generalizes classical spin models on a lattice by incorporating effective transport of polarity molecules between neighboring sites. We account for an external field and for ferromagnetic interactions between sites and prescribe the time-evolution of the system using two distinct dissipative classes for non-conserved and conserved variables representing polarity orientation and magnitude, respectively. We observe two main types of steady-state configurations --disordered configurations and patterns of highly polar spots surrounded by regions with low polarity-- and we characterise patterns and transitions between configurations. Our results may provide alternative pattern-generating mechanisms for materials endowed with polarity fields.

description: We report on temperature dependent measurements of the Longitudinal Spin Seebeck Effect (LSSE) in the mixed valent manganite La$_{0.7}$Ca$_{0.3}$MnO$_3$. By disentangling the contribution arising due to the Anisotropic Nernst effect, we observe that these two thermally driven phenomena vary disparately with temperature. In a narrow low temperature regime, the LSSE exhibits a $T^{0.55}$ dependence, which matches well with that predicted by the magnon-driven spin current model. Across the double exchange driven paramagnetic-ferromagnetic transition, the LSSE exponent is significantly higher than the magnetization one. These observations highlights the importance of individually ascertaining the temperature evolution of different mechanisms which contribute to the measured spin Seebeck signal.

description: Protein kinases are critical components of a myriad biological processes and strongly associated with various dis?eases. While kinase research has been a point of focus in biomedical research for several decades, a large portion of the kinome is still considered understudied or“dark,” because prior research is targeted towards a subset of kinases with well-established roles in cellular processes. We present an empirical and in-silico hybrid workfow to extend the functional knowledge of understudied kinases. Utilizing multiplex peptide activity arrays and robust in-silico analyses, we extended the functional knowledge of fve dark tyrosine kinases (AATK, EPHA6, INSRR, LTK, TNK1) and explored their roles in schizophrenia, Alzheimer’s dementia (AD), and major depressive disorder (MDD). Using this hybrid approach, we identifed 195 novel kinase-substrate interactions with variable degrees of afnity and linked extended functional networks for these kinases to biological processes that are impaired in psychiatric and neuro?logical disorders. Biochemical assays and mass spectrometry were used to confrm a putative substrate of EPHA6, an understudied dark tyrosine kinase. We examined the EPHA6 network and knowledgebase in schizophrenia using reporter peptides identifed and validated from the multi-plex array with high afnity for phosphorylation by EPHA6. Identifcation and confrmation of putative substrates for understudied kinases provides a wealth of actionable infor?mation for the development of new drug treatments as well as exploration of the pathophysiology of disease states using signaling network approaches.

In order to confirm that the clusters members extracted by the method correspond to actual globular clusters, the spatial distribution, the vector point diagram of the proper motions and the colour-magnitude diagrams are analysed. We apply the developed method to eight clusters: NGC 1261, NGC 3201, NGC 6139, NGC 6205, NGC 6362, NGC 6397, NGC 6712 and Palomar 13; we show the number of members extracted, the mean proper motions derived from them and finally we compare our results with other authors. In order to analyse the efficiency of the extraction method we perform an estimation of the completeness and the degree of contamination of the extracted members.

description: We present a gauge-invariant formalism to study the evolution of curvature perturbations in a Friedmann-Robertson-Walker universe filled by multiple interacting fluids. We resolve arbitrary perturbations into adiabatic and entropy components and derive their coupled evolution equations. We demonstrate that perturbations obeying a generalised adiabatic condition remain adiabatic in the large-scale limit, even when one includes energy transfer between fluids. As a specific application we study the recently proposed curvaton model, in which the curvaton decays into radiation. We use the coupled evolution equations to show how an initial isocurvature perturbation in the curvaton gives rise to an adiabatic curvature perturbation after the curvaton decays.

description: Prochlorococcus are the most abundant photosynthetic organisms in the modern ocean. A massive DNA loss event occurred in their early evolutionary history, leading to highly reduced genomes in nearly all lineages, as well as enhanced efficiency in both nutrient uptake and light absorption. The environmental landscape that shaped this ancient genome reduction, however, remained unknown. Through careful molecular clock analyses, we established that this Prochlorococcus genome reduction occurred during the Neoproterozoic Snowball Earth climate catastrophe. The lethally low temperature and exceedingly dim light during the Snowball Earth event would have inhibited Prochlorococcus growth and proliferation, and caused severe population bottlenecks. These bottlenecks are recorded as an excess of deleterious mutations accumulated across genomic regions and inherited by descendant lineages. Prochlorococcus adaptation to extreme environmental conditions during Snowball Earth intervals can be inferred by tracing the evolutionary paths of genes that encode key metabolic potential. Key metabolic innovation includes modified lipopolysaccharide structure, strengthened peptidoglycan biosynthesis, the replacement of a sophisticated circadian clock with an hourglass-like mechanism that resets daily for dim light adaption and the adoption of ammonia diffusion as an efficient membrane transporter-independent mode of nitrogen acquisition. In this way, the Neoproterozoic Snowball Earth event may have altered the physiological characters of Prochlorococcus, shaping their ecologically vital role as the most abundant primary producers in the modern oceans.

description: School food authorities (SFAs) run meal service programs in each school district and are reimbursed at a national rate for meals served to eligible students participating in the National School Lunch Program (NSLP). Previous research (Ollinger et al., 2011) showed that meal costs were lower for SFAs that serve more meals, and Newman, Ralston, and Clauson (2008) found that some large volume buyers reduce their food costs by negotiating price discounts. This paper builds on that research by examining factors affecting purchase costs. The main findings are that cost dropped with the volume of product purchased and with the number of meals served for most foods and varied across regions. A major surprise was that small and middle size SFAs in buying cooperatives and SFAs using school food management companies had higher costs than did other SFAs not using co-operatives or food management companies.

description: This document is a deliverable of the Social Sciences and Humanities Open Cloud project (SSHOC). It is a report about the Ethnic and Migrant Minorities (EMM) Survey Registry: an online, publicly available database and tool that displays compiled survey-level metadata of existing quantitative surveys undertaken with ethnic and migrant minority (EMM) populations in Europe, and which is jointly being produced by SSHOC’s Task 9.2 Ethnic and Migration Studies (part of Work Package 9 Data Communities) in collaboration with COST Action 16111 – ETHMIGSURVEYDATA (a network of more than 200 European researchers active in the ethnic and migration studies field) and FAIRETHMIGQUANT (a French Agence Nationale de la Recherche (ANR)-funded Open Science project). This report is intended to inform prospective users of the EMM Survey Registry (i.e. (non)academic researchers, policymakers, and other practitioners interested in quantitative surveys on EMMs’ integration) about what the registry is and how it could be leveraged for their own research and/or policy-related activities. It is also aimed at providing individuals and organisations involved in data curation with a concrete example of how a FAIR-friendly tool for the social sciences can be created from a bottom-up approach, where the data community is the main driver. The report begins by illustrating the role of the FAIR (Findable, Accessible, Interoperable, Reusable) principles in shaping how the EMM Survey Registry has been designed, developed, and delivered. The EMM Survey Registry is currently available in ‘beta’ version, and information for over 400 surveys from 11 different countries are publicly being displayed. More specifically the report follows the trajectory of the EMM Survey Registry, describing how stakeholders specialising in data production, usage, storage, and management were routinely leveraged from conception to delivery (of its current ‘beta’ version), in order to align this registry with the FAIR principles as much as possible. The report concludes by describing the concerted effort the Task 9.2 team is making to facilitate short and long-term sustainability of the EMM Survey Registry by strategically connecting and liaising with potential users interested in quantitative surveys undertaken with EMMs.

description: We investigate the relationship between the quasi-thermal baryon-related photosphere in relativistic outflows, and the internal shocks arising outside them, which out to a limiting radius may be able to create enough pairs to extend the optically thick region. Variable gamma-ray light curves are likely to arise outside this limiting pair-forming shock radius, while X-ray excess bursts may arise from shocks occurring below it; a possible relation to X-ray flashes is discussed. This model leads to a simple physical interpretation of the observational gamma-ray variability-luminosity relation.

description: Water quality trading (WQT) has been suggested as a cost effective approach to achieve water quality goals for many watersheds (EPA, 2007), including the Jordan Lake watershed in North Carolina. Although, theory supports the concept, its implementation has experienced a numbers of failures in the United States. A broad spectrum of physical, social, economic, and intuitional factors have diverted success. One of the institutional hindrances is the WQT baseline. WQT baseline is a reference point that must be met by credit sellers and buyers before being allowed to buy or sell credits. Favorable (unfavorable) weather compared to the baseline can result in gains (losses) attributed to conservation technology. We construct a WQT market applied to the new Jordan Lake Watershed program in North Carolina to examine the role of weather on baseline period as related to total nitrogen (TN) loads in Jordan Lake. Results of our models show that the baseline weather condition has a profound impact on the water quality credits supply. The purpose of this study is to alert policy makers to this issue and to suggest ways to better match the baseline incentives with emission reduction goals when taking weather variability and trends into account.
Galaxy dynamics tracing quantum cosmology beyond ΛCDM below the de Sitter scale of acceleration
Creators: name: van Putten, Maurice H.P.M.

Year: 2024

description: In disks of spiral galaxies, the baryonic Tully-Fisher relation (bTFR) shows a discrepancy α > aN between observed orbital acceleration α and expected Newtonian acceleration aN based on baryonic matter and Newton's law of gravitation. We consider sensitivity of weak gravitation in galaxy dynamics to the de Sitter scale of acceleration adS=cH of the background cosmology, given by the velocity of light c and the Hubble parameter H. The onset to bTFR is identified with crossing of the Rindler horizon and Hubble horizon at accelerations adS, giving rise to a sharp essentially C0-transition to anomalous dynamics α > aN across ζ=1, where ζ=aN/adS. This C0-transition is observed at 6σ significance in SPARC. The anomalous dynamics derives from reduced inertia (a symmetry of the Hamiltonian of orbital motion) due to a Hubble cut-off of potential energy in the Rindler frame of the orbiting stars. Equivalently, this reduced inertia is identified with a dimensional reduction in the Green's function of the Laplace operator. The bTFR is shown to be parameterized by a Milgrom parameter a0=c2/(2π) \sqrt{J}, where J is the trace of the Schouten tensor. This interpretation unifies, with no free parameters, the short time scales in galaxy dynamics and accelerated galaxy formation at cosmic dawn ('JWST Impossible galaxies'). By this sensitivity, spiral galaxies can be used as tracers of background cosmology, providing novel ways to measure the Hubble parameter H0 by resolving the location of the C0-transition at ζ=1. Combined with a0, the resulting H0 carries an associated deceleration parameter q0 through J=(1-q)H^2.
