description: A class of generalized Galileon cosmological models, which can be described by a point-like Lagrangian, is considered in order to utilize Noether's Theorem to determine conservation laws for the field equations. In the Friedmann-Lemaître-Robertson-Walker universe, the existence of a nontrivial conservation law indicates the integrability of the field equations. Due to the complexity of the latter, we apply the differential invariants approach in order to construct special power-law solutions and study their stability.

description: This study focuses on the formation of two molecules of astrobiological importance - glycolaldehyde (HC(O)CH2OH) and ethylene glycol (H2C(OH)CH2OH) - by surface hydrogenation of CO molecules. Our experiments aim at simulating the CO freeze-out stage in interstellar dark cloud regions, well before thermal and energetic processing become dominant. It is shown that along with the formation of H2CO and CH3OH - two well established products of CO hydrogenation - also molecules with more than one carbon atom form. The key step in this process is believed to be the recombination of two HCO radicals followed by the formation of a C-C bond. The experimentally established reaction pathways are implemented into a continuous-time random-walk Monte Carlo model, previously used to model the formation of CH3OH on astrochemical time-scales, to study their impact on the solid-state abundances in dense interstellar clouds of glycolaldehyde and ethylene glycol.

description: Every observation of astrophysical objects involving a spectrum requires atomic data for the interpretation of line fluxes, line ratios and ionization state of the emitting plasma. One of the processes which determines it is collisional ionization. In this study an update of the direct ionization (DI) and excitation-autoionization (EA) processes is discussed for the H to Zn-like isoelectronic sequences. In the last years new laboratory measurements and theoretical calculations of ionization cross sections have become available. We provide an extension and update of previous published reviews in the literature. We include the most recent experimental measurements and fit the cross sections of all individual shells of all ions from H to Zn. These data are described using an extension of Younger's and Mewe's formula, suitable for integration over a Maxwellian velocity distribution to derive the subshell ionization rate coefficients. These ionization rate coefficients are incorporated in the high-resolution plasma code and spectral fitting tool SPEX V3.0.

description: The present paper deals with a prey-predator model with prey refuge proportion to both species and independent harvesting of each species. Our study shows that using refuge as control, it can break the limit circle of the system and reach the required state of equilibrium level. It is established the optimal harvesting policy. The boundedness, feasibility of interior equilibria, bionomic equilibrium have been determined. The main observation is that coefficient of refuge plays an important role in regulating the dynamics of the present system. Moreover the variation of the coefficient of refuge change the system from stable to unstable and vice-versa. Some numerical illustration are given in order to support of our analytical and theoretical findings.

description: We have constructed the most-comprehensive catalog of photometry and proper motions ever assembled for a globular cluster (GC). The core of $ω$Cen has been imaged over 650 times through WFC3's UVIS and IR channels for the purpose of detector calibration. There exist from 4 to over 60 exposures through each of 26 filters, stretching continuously from F225W in the UV to F160W in the infrared. Furthermore, the 11-year baseline between these data and a 2002 ACS survey has allowed us to more than double the proper-motion accuracy and triple the number of well-measured stars compared to our previous groundbreaking effort. This totally unprecedented complete spectral coverage for over 470,000 stars within the cluster's core, from the tip of the red-giant branch down to the white dwarfs, provides the best astro-photometric observational data base yet to understand the multiple-population phenomenon in any GC. In this first paper of the series we describe in detail the data-reduction processes and deliver the astro-photometric catalog to the astronomical community.

description: Very special relativity (VSR) keeps the main features of special relativity but breaks rotational invariance due to an intrinsic preferred direction. We study the VSR modified extended BRST and anti-BRST symmetry of the Batalin-Vilkovisky (BV) actions corresponding to the $p=1,2,3$-form gauge theories. Within VSR framework, we discuss the extended BRST invariant and extended BRST and anti-BRST invariant superspace formulations for these BV actions. Here we observe that the VSR modified extended BRST invariant BV actions corresponding to the $p=1,2,3$-form gauge theories can be written manifestly covariant manner in a superspace with one Grassmann coordinate. Moreover, two Grassmann coordinates are required to describe the VSR modified extended BRST and extended anti-BRST invariant BV actions in a superspace. These results are consistent with the Lorentz invariant (special relativity) formulation.

description: Heusler alloys are promising for several applications, including magnetic refrigeration, due to high magnetocaloric and magnetovolume effects. One way to optimize this potential is by increasing the magnetovolume effect. Using density functional theory with the Korringa-Kohn-Rostoker method, we calculate the effective exchange interaction energies and corresponding mean field Curie temperature as a function of the volume (hydrostatic pressure) in several L2 1 -type Co 2 YZ Heusler alloys. Different qualitative trends and signs of the pressure derivatives of the Curie temperature and moments are found among these compounds, discussed and compared with previous calculations and experiments.

description: We propose a new technique for radio interferometry to obtain super-resolution full polarization images in all four Stokes parameters using sparse modeling. The proposed technique reconstructs the image in each Stokes parameter from the corresponding full-complex Stokes visibilities by utilizing two regularization functions: the $\ell _1$-norm and total variation (TV) of the brightness distribution. As an application of this technique, we present simulated linear polarization observations of two physically motivated models of M87 with the Event Horizon Telescope (EHT). We confirm that $\ell _1$+TV regularization can achieve an optimal resolution of $\sim 25-30$\% of the diffraction limit $λ/D_{\rm max}$, which is the nominal spatial resolution of a radio interferometer for both the total intensity (i.e. Stokes $I$) and linear polarizations (i.e. Stokes $Q$ and $U$). This optimal resolution is better than that obtained from the widely used Cotton-Schwab CLEAN algorithm or from using $\ell _1$ or TV regularizations alone. Furthermore, we find that $\ell _1$+TV regularization can achieve much better image fidelity in linear polarization than other techniques over a wide range of spatial scales, not only in the super-resolution regime, but also on scales larger than the diffraction limit. Our results clearly demonstrate that sparse reconstruction is a useful choice for high-fidelity full-polarimetric interferometric imaging.

Continued Fractions and $q$-Series Generating Functions for the Generalized Sum-of-Divisors Functions
Creators: name: Schmidt, Maxie D.
Publisher: name: arXiv
Year: 2017
Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: We construct new continued fraction expansions of Jacobi-type J-fractions in $z$ whose power series expansions generate the ratio of the $q$-Pochhamer symbols, $(a; q)_n / (b; q)_n$, for all integers $n \geq 0$ and where $a,b,q \in \mathbb{C}$ are non-zero and defined such that $|q| < 1$ and $|b/a| < |z| < 1$. If we set the parameters $(a, b) := (q, q^2)$ in these generalized series expansions, then we have a corresponding J-fraction enumerating the sequence of terms $(1-q) / (1-q^{n+1})$ over all integers $n \geq 0$. Thus we are able to define new $q$-series expansions which correspond to the Lambert series generating the divisor function, $d(n)$, when we set $z \mapsto q$ in our new J-fraction expansions. By repeated differentiation with respect to $z$, we also use these generating functions to formulate new $q$-series expansions of the generating functions for the sums-of-divisors functions, $σ_α(n)$, when $α\in \mathbb{Z}^{+}$. To expand the new $q$-series generating functions for these special arithmetic functions we define a generalized classes of so-termed Stirling-number-like "$q$-coefficients", or Stirling $q$-coefficients, whose properties, relations to elementary symmetric polynomials, and relations to the convergents to our infinite J-fractions are also explored within the results proved in the article.

description: In the present work, we have studied for the first time the combined effect of both sonication and precipitation pH on the structure of amorphous zirconia gels synthesized from zirconium(IV) propoxide. The techniques of small-angle neutron and X-ray scattering (SANS and SAXS) and low temperature nitrogen adsorption provided the integral data on the changes in the microstructure and mesostructure of these materials caused by ultrasonic (US) treatment. Amorphous ZrO2.xH2O synthesized under ultrasonic treatment was found to possess a very structured surface, characterized by the surface fractal dimension 2.9-3.0, compared to 2.3-2.5 for the non US-assisted synthesis, and it was also found to possess a higher specific surface area, while the sizes of the primary particles remain unchanged.

description: The objective of this deliverable is to present the activity done in the reporting period (May 2019 - July 2020) to operate and coordinate the common PRACE Operational Services, foreseen by Task 6.1 of WP6 within the PRACE-6IP project. The operation of the PRACE distributed HPC infrastructure involves the coordination of a set of services which integrate the Tier-0 systems and a number of national Tier-1 systems in a “single” pan-European HPC infrastructure.
 This work is the continuation of the work done by Task 6.1 in the previous PRACE-IP projects to provide continuity to the PRACE Operational Services for the HPC ecosystem.
 Eight Tier-0 systems in five countries were operational in the first year of the PRACE-6IP project period.
 Furthermore, operational support has been provided to twenty national Tier-1 systems that provide services for Tier-0 (i.e. used from SMEs for the SHAPE activity, or as stepping stone towards Tier-0 systems, or to prototype and asses new Operational Services). These Tier-1 systems are distributed among fifteen different countries, ensuring a wide distribution of the European HPC ecosystem and serving the DECI calls.
 A new version of the PRACE Service Catalogue, which describes the PRACE common services, has been created and approved by the PRACE BoD to further guide the operational activity. The PRACE Service Catalogue represents a living document reflecting also the requirement to develop new user-friendly services in the context of PRACE.
 Based on the procedures for incident and change management, the complete set of PRACE common services as defined in the PRACE Service Catalogue (Networking, Data, Compute, AAA and Security, User, Monitoring and Generic) have been operated and monitored on a day-by-day basis to assure continuity and integrity of the services.
 The Security Forum, responsible for all security related activities, is also coordinated by Task 6.1. This is achieved with periodic teleconferences to monitor the infrastructure and prevent possible incidents which could cause vulnerabilities on the PRACE RI.

description: Ant foragers provide food to the rest of the colony, often requiring transport over long distances. Foraging for liquid is challenging because it is difficult to transport and share. Many social insects store liquids inside the crop to transport them to the nest, and then regurgitate to distribute to nest-mates through a behaviour called trophallaxis. Some ants instead transport fluids with a riskier behaviour called pseudotrophallaxis – holding a drop of liquid between the mandibles through surface tension. Ants share this droplet with nest-mates without ingestion or regurgitation. We hypothesised that ants optimize their liquid-collection approach depending on viscosity. Using an ant that employs both trophallaxis and pseudotrophallaxis, we investigated the conditions where each liquid-collection behaviour is favoured by measuring biophysical properties, collection time, and reaction to food quality for typical and viscosity-altered sucrose solutions. We found that ants collected more liquid per unit time by mandibular grabbing than by drinking. At high viscosities ants switched liquid collection method to mandibular grabbing in response to viscosity and not to sweetness. Our results demonstrate that ants change transport and sharing methods according to viscosity – a natural proxy for sugar concentration – increasing the mass of sugar returned to the nest per trip.

description: The variational cluster approximation is used to study the isotropic triangular-lattice Hubbard model at half filling, taking into account the nearest-neighbor ($t_1$) and next-nearest-neighbor ($t_2$) hopping parameters for magnetic frustrations. We determine the ground-state phase diagram of the model. In the strong correlation regime, the 120$^\circ$ Néel and stripe ordered phases appear, and a nonmagnetic insulating phase emerges in between. In the intermediate correlation regime, the nonmagnetic insulating phase expands to a wider parameter region, which goes into a paramagnetic metallic phase in the weak correlation regime. The critical phase boundary of the Mott metal-insulator transition is discussed in terms of the van Hove singularity evident in the calculated density of states and single-particle spectral function.

description: We show that for a heavy vector-like quark model with a down type isosinglet, branching ratio for $c\rightarrow uγ$ decay is enhanced by more than $\mathcal{O}(10^2)$ as compared to that in the Standard model when QCD corrections to next-to-leading order are incorporated. In a left-right symmetric model (LRSM) along with a heavy vector-like fermion, enhancement of this order can be achieved at the bare (QCD uncorrected) level itself. We propose that a measurement of the photon polarization could be used to signal the presence of such new physics inspite of the large long distance effects. We find that there is a large region within the allowed parameter space of model with vector-like quark with additional left-right symmetry, where depending on the exact size of the long distance contribution, the photon polarization can be dominantly right-handed.

description: Our Keck/NIRC2 imaging survey searches for stellar companions around 144 systems with radial velocity (RV) detected giant planets to determine whether stellar binaries influence the planets' orbital parameters. This survey, the largest of its kind to date, finds eight confirmed binary systems and three confirmed triple systems. These include three new multi-stellar systems (HD 30856, HD 86081, and HD 207832) and three multi-stellar systems with newly confirmed common proper motion (HD 43691, HD 116029, and HD 164509). We combine these systems with seven RV planet-hosting multi-stellar systems from the literature in order to test for differences in the properties of planets with semimajor axes ranging between 0.1-5 au in single vs multi-stellar systems. We find no evidence that the presence or absence of stellar companions alters the distribution of planet properties in these systems. Although the observed stellar companions might influence the orbits of more distant planetary companions in these systems, our RV observations currently provide only weak constraints on the masses and orbital properties of planets beyond 5 au. In order to aid future efforts to characterize long period RV companions in these systems, we publish our contrast curves for all 144 targets. Using four years of astrometry for six hierarchical triple star systems hosting giant planets, we fit the orbits of the stellar companions in order to characterize the orbital architecture in these systems. We find that the orbital plane of the secondary and tertiary companions are inconsistent with an edge-on orbit in four out of six cases.

description: Diamond-based magnetic field sensors have attracted great interest in recent years. In particular, wide-field magnetic imaging using nitrogen-vacancy (NV) centers in diamond has been previously demonstrated in condensed matter, biological, and paleomagnetic applications. Vector magnetic imaging with NV ensembles typically requires an applied field (>10 G) to separate the contributions from four crystallographic orientations, hindering studies of magnetic samples that require measurement in low or independently specified bias fields. Here we decompose the NV ensemble magnetic resonance spectrum without such a bias field by modulating the collected light at the microscope's Fourier plane. In addition to enabling vector magnetic imaging at arbitrarily low fields, our method can be used to extend the dynamic range at a given bias field. As demonstrated here, optically-detected diamond magnetometry stands to benefit from Fourier optical approaches, which have already found widespread utility in other branches of photonics.

description: A parallel iterative layered-medium integral-equation solver is presented for fast and scalable network parameter extraction of high-fidelity full-size electronic package models. The solver relies on a 2-D fast-Fourier-transform (FFT)-based acceleration method, a sparse preconditioner, and a scalable parallelization method to reduce the computational costs as well as advanced lumped-port models to improve the accuracy of network parameter extraction. To be able to analyze full-size electronic package models, the solver is integrated to a reduced-domain layered-medium integral-equation formulation that models large portions of planar conductors using layered medium Green’s functions. To demonstrate the method’s efficiency and applicability to complex electronic packaging problems, various package models with increasingly higher fidelities and larger sizes are analyzed, their numerical results are validated, and the costs are quantified. The studied models include a full-size package model with 304 differential-pair traces that fan out on two different routing layers that carry signals from the chip to the board through 10 metallization layers; the model contains 3127 plated-through-hole core-layer vias, 1216 stacked microvias connected to the traces, and ~3×10⁴ single-layer microvias that stitch metallization layers. The proposed parallel layered-medium integral-equation methods reduced the number of unknowns for the full-wave analysis of this model to only ~4.9×10⁶; using 1536 processes on a petascale cluster, the methods required a wall clock time of ̃ 0.58 seconds per iteration, ~28 minutes per excitation, and ~560 hours per frequency to extract the 1216-port network parameters.

description: Non-local carrier injection/detection schemes lie at the very foundation of information manipulation in integrated systems. This paradigm consists in controlling with an external signal the channel where charge carriers flow between a "source" and a well separated "drain". The next generation electronics may operate on the spin of carriers instead of their charge and germanium appears as the best hosting material to develop such a platform for its compatibility with mainstream silicon technology and the long electron spin lifetime at room temperature. Moreover, the energy proximity between the direct and indirect bandgaps allows for optical spin injection and detection within the telecommunication window. In this letter, we demonstrate injection of pure spin currents (\textit{i.e.} with no associated transport of electric charges) in germanium, combined with non-local spin detection blocks at room temperature. Spin injection is performed either electrically through a magnetic tunnel junction (MTJ) or optically, exploiting the ability of lithographed nanostructures to manipulate the distribution of circularly-polarized light in the semiconductor. Pure spin current detection is achieved using either a MTJ or the inverse spin-Hall effect (ISHE) across a platinum stripe. These results broaden the palette of tools available for the realization of opto-spintronic devices.

description: The electromagnetic field in a magnetized neutron star and the underlying volume charges and currents are found. A general case of a rigidly rotating neutron star with infinite conductivity, arbitrary distribution of the internal magnetic field, arbitrarily changing angular velocity, and arbitrary surface velocity less than the velocity of light is considered. Quaternions are used to describe rotation and determine the magnetic field. It is shown that the charge density is not equal to and can exceed significantly the common Goldreich-Julian density. Moreover, corrections to the magnetic field due to stellar rotation are zero. For a rotating neutron star, twisting magnetic field lines causes charge accumulation and current flows. This fact shows a possible link between changing internal magnetic field topology and observed activity of neutron stars.

title: Evaluating role of phosphatidic acid in cold stress tolerance in silage-corn
Creators: name: Wu, Jiaxu
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: Extreme cold weather conditions and short growing seasons during early seedling establishment are the major causes of the low forage yield of silage corn (Zea mays L.). The experiments were conducted under controlled environmental conditions to determine the effects of different temperature regimes (25°C, 20°C, 15°C, 10°C and 5°C) on morphological, physiological and biochemical attributes of two silage-corn genotypes (Yukon-R, A4177G3-RIB) during the early growth stage. Results indicated that cold stress significantly affected seedling growth, photosynthesis, reactive oxygen species (ROS) accumulation and antioxidant enzyme activities. The chlorophyll content, photosynthetic rate, and maximal photochemical efficiency of photosystem-II were drastically decreased under cold conditions. Besides, cold stress induced the accumulation of hydrogen peroxide and malonaldehyde contents. Increased proline content and enzymatic antioxidants were found to alleviate oxidative damage under cold stress. Yukon-R showed significantly higher proline content, and enzymatic antioxidant activities than A4177G3-RIB when the temperature was lower than 10°C. Furthermore, the role of phospholipids, particularly phosphatidic acid (PA) in cold tolerance was investigated. Lipidomic results showed that the membrane lipids phosphatidylcholine and phosphatidylglycerol levels were decreased in contrast to increased levels of phosphatidylethanolamine and PA under cold temperatures. Specifically, Yukon-R showed significantly higher PA, phosphatidylcholine and phosphatidylglycerol contents than A4177G3-RIB in both leaf and root membranes under cold conditions, suggesting their positive roles (stress signaling transduction, maintaining cellular integrity and photosynthetic processes, respectively) in cold tolerance. Taken together, the study suggests that: (i) Yukon-R could be considered a potential candidate genotype to be grown in the boreal climate; (ii) phospholipid remodeling and PA accumulation in leaf and root are required for silage corn cold stress acclimation at the early growth stage.

description: Avalanche photodiodes (APDs) are a practical option for space-based quantum communications requiring single-photon detection. However, radiation damage to APDs significantly increases their dark count rates and reduces their useful lifetimes in orbit. We show that high-power laser annealing of irradiated APDs of three different models (Excelitas C30902SH, Excelitas SLiK, and Laser Components SAP500S2) heals the radiation damage and substantially restores low dark count rates. Of nine samples, the maximum dark count rate reduction factor varies between 5.3 and 758 when operating at minus 80 degrees Celsius. The illumination power to reach these reduction factors ranges from 0.8 to 1.6 W. Other photon detection characteristics, such as photon detection efficiency, timing jitter, and afterpulsing probability, remain mostly unaffected. These results herald a promising method to extend the lifetime of a quantum satellite equipped with APDs.

Towards a cohesive approach for measuring rewilding progress: An analysis of the current proposals and a suggestion of a future framework

description: Rewilding has emerged as a promising concept for ecological restoration and nature conservation. While it is gaining increasing interest from restoration practitioners, conservationists, decision-makers, funders and even philosophers for its engaging narrative, it has been criticised for lacking a consistent best-practice. In order to keep up with the requirements of evidence-based restoration and conservation, rewilding has to build its own evidence base. For this, the crucial step is to measure rewilding progress, i.e. monitor and evaluate the outcomes, put the findings into the greater context and make them accessible for future use. This work reviews the currently available literature on how rewilding progress can be measured and the different approaches are critically discussed. The literature analysis has revealed six approaches that focus on monitoring and evaluating rewilding outcomes. Four of these approaches focus mainly on the ecological dimension of rewilding, from which two concentrate more narrowly only on species distribution and vegetation dynamics. Two approaches have been proposed for measuring the socio-economic impacts of rewilding and how to improve decision-making and overcome anticipated challenges associated with rewilding. The analysis of the six different approaches has revealed a focus on the ecological dimension of rewilding, with promising suggestions of how to comprehensively monitor and evaluate ecological outcomes. However, the socio-economic dimension remains under-represented, still lacking an appropriate framework suited to the particularities of rewilding. For this reason, a draft framework comprising all rewilding dimensions has been developed based on the findings of the literature analysis. This framework helps to improve the measuring of rewilding progress, enables building up rewilding’s evidence base and, with this, guiding it towards a convincing and legitimate pathway for ecosystem recovery that integrates people and nature.

description: In the landscape perspective, our Universe begins with a quantum tunneling from an eternally-inflating parent vacuum, followed by a period of slow-roll inflation. We investigate the tunneling process and calculate the probability distribution for the initial conditions and for the number of e-folds of slow-roll inflation, modeling the landscape by a small-field one-dimensional random Gaussian potential. We find that such a landscape is fully consistent with observations, but the probability for future detection of spatial curvature is rather low, $P \sim 10^{-3}$.

description: In order to improve the time precision of detectors based on diamonds sensors we have built a detector with two scCVD layers connected in parallel to the same amplifier. This note describes the design and the first measurements of such a prototype performed on a particle beam at CERN. With this different configuration we have obtained an improvement on the timing precision of a factor of 1.6-1.7 with respect to a single layer scCVD diamond detector.

description: We present results on the dust attenuation of galaxies at redshift $\sim3-6$ by studying the relationship between the UV spectral slope ($β_{\rm UV}$) and the infrared excess (IRX; $L_{\rm IR}$/$L_{\rm UV}$) using ALMA far-infrared continuum observations. Our study is based on a sample of 67 massive, star-forming galaxies with a median mass of $M_{\ast}\sim 10^{10.7}\,M_{\rm \odot}$ spanning a redshift range $z=2.6-3.7$ (median $z=3.2$) that were observed with ALMA at $λ_{rest}=300\,{\rm μm}$. Both the individual ALMA detections (41 sources) and stacks including all galaxies show the IRX-$β_{\rm UV}$ relationship at $z\sim3$ is mostly consistent with that of local starburst galaxies on average. However, we find evidence for a large dispersion around the mean relationship by up to $\pm0.5$ dex. Nevertheless, the locally calibrated dust correction factors based on the IRX-$β_{\rm UV}$ relation are on average applicable to main-sequence $z\sim3$ galaxies. This does not appear to be the case at even higher redshifts, however. Using public ALMA observations of $z\sim4-6$ galaxies we find evidence for a significant evolution in the IRX-$β_{\rm UV}$ and the IRX-$M_{\ast}$ relations beyond $z\sim3$ toward lower IRX values. We discuss several caveats that could affect these results, including the assumed dust temperature. ALMA observations of larger $z>3$ galaxy samples will be required to confirm this intriguing redshift evolution.
