RC Tab

description: Azure doesn’t provide a flexible multi-subscription management system that would allow setting automatic hard budgetary limits on subscriptions (accounts) that are paid via the pay-as-you-go or prepayment (monetary commitments) models. For example, it is not straightforward to set expiry dates or budget limits that would automatically turn subscriptions off when one of the criteria is met. The Turing uses a multi-subscription model on Azure where we typically dedicate one subscription per project. This results in having more than a hundred subscriptions active at any given moment in time. Without being able to set automatic budgetary limits on subscriptions we would have to either dedicate most of the Research Computing team’s capacity for manual monitoring and management of subscriptions and would have to limit which services researchers are able to use. To address this challenge we have developed RC Tab, a software framework designed to support Azure subscription management, reporting, and usage monitoring. RC Tab comprises of multiple modules, such as a web frontend, command-line interface, and email notifications. It is open-source, configurable, quick to deploy and has been in active use at the Turing for several months. RC Tab has significantly reduced the amount of time the team spends on managing Azure subscriptions allowing us to concentrate on further developing the cloud experience at The Turing. In this presentation, we would like to share our group’s experience of managing cloud computing resources at The Turing, as well as advertise and share RC Tab with other organisations that are using, or planning to use, Azure.

description: Two forms of G4-DNA, with parallel and pairwise anti-parallel strands, are studied using atomic force microscopy. The directionality of the strands affects the molecules' structural properties (different height and length) and their electrical polarizability. Parallel G4-DNA is twice as polarizable as anti-parallel G4-DNA, suggesting it is a better electrical wire for bio-nanoelectronics.

description: The expression of virulence factors, such as biofilm formation, in association with the acquisition of resistance to multiple drugs, has evidenced the need for new and effective antimicrobial agents against Staphylococcus aureus. The evaluation of the pharmacological properties of plant-derived compounds is a promising alternative to the development of new antimicrobials. In this study, we aimed to evaluate the antibacterial, antibiofilm, and the synergistic and cytotoxic effects of netzahualcoyonol isolated from Salacia multiflora (Lam.) DC. roots. Netzahualcoyonol presented bacteriostatic (1.56–25.0 µg/mL) and bactericidal (25.0–400.0 µg/mL) effects against Gram-positive bacteria, disrupted the biofilm of S. aureus, and presented a synergistic effect after its combination with β-lactams and aminoglycosides. The low cytotoxicity of netzahualcoyonol (Selectivity Index (SI) for S. aureus (2.56), S. saprophyticus (20.56), and Bacillus subtilis (1.28)) suggests a good security profile. Taken together, these results show that netzahualcoyonol is promising for the development of a new effective antibacterial agent.

description: A new glycoiridoid (1) together with seven (7) known compounds were isolated from the methanol crude extract of the root bark of Stereospermum kunthianum using chromatography methods. Their structures were elucidated using HR-ESI-MS, 1 D- & 2 D-NMR spectroscopies in comparison with previous literature. The antioxidant activity was investigated by using FRAP, DPPH, ABTS and HRSA methods while the antibacterial activity was assays on Escherichia coli (ATCC25922) and Salmonella typhimurium (ATCC14028) strains. The results showed that the isolated compounds had significantly (p < 0.01) high radical scavenging (IC50) and reducing power activity. All bacteria strains showed important minimal inhibitory concentration activity against isolated compounds started at 5 mg/mL with an inhibition zone of 6 mm. Thus, the isolated compounds in S. kunthianum justify the use of the plant in traditional medicine for the treatment of various diseases in humans. These isolated compounds can be used for formulation of new drug discovery to treat infectious diseases.

description: Due to the growing capacity of gravitational-wave astronomy and black-hole imaging, we will soon be able to emphatically decide if astrophysical objects lurking in galactic centers are black holes. Sgr A*, one of the most prolific astronomical radio sources in our galaxy, is the focal point for tests of general relativity. Current mass and spin constraints predict that the central object of the Milky Way is supermassive and slowly rotating, thus can be conservatively modeled as a Schwarzschild black hole. The well-established presence of accretion disks and astrophysical environments around supermassive objects can deform their geometry and complicate their observational scientific yield. Here, we study extreme-mass-ratio binaries comprised of a minuscule secondary object inspiraling onto a supermassive Zipoy-Voorhees compact object; the simplest exact solution of general relativity that describes a static, spheroidal deformation of Schwarzschild spacetime. We examine geodesics of prolate and oblate deformations for generic orbits and reevaluate the non-integrability of Zipoy-Voorhees spacetime through the existence of resonant islands in the orbital phase space. By including radiation loss with post-Newtonian techniques, we evolve stellar-mass secondary objects around a supermassive Zipoy-Voorhees primary and find clear imprints of non-integrability in these systems. The peculiar structure of the primary, allows for, not only typical single crossings of transient resonant islands, that are well-known for non-Kerr objects, but also inspirals that traverse through several islands, in a brief period of time, that lead to multiple glitches in the gravitational-wave frequency evolution of the binary. The detectability of glitches with future spaceborne detectors can, therefore, narrow down the parameter space of exotic solutions that, otherwise, can cast identical shadows with black holes.

description: A new prenylated kaempferol, conglomeratin (1), alongside 7 known compounds including flavonoids (2 and 3), ellagic acid derivatives (4 and 5), triterpenoids (6 and 7), and a coumarin (8) were isolated from the leaves (1 − 5) and stem bark (6 − 8) of Macaranga conglomerata. Their structures were elucidated using spectroscopic and spectrometric techniques. The antibacterial assay was performed using disc diffusion method against Gram-positive and Gram-negative microorganisms. Compound 1 was significantly active against Pseudomonas aeruginosa ATCC 27853 (MIC = 7.8 µg/mL) and moderately active towards Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922 and Klebsiella pneumoniae ATCC 31488 (MIC = 62.5 µg/mL). Compound 2 showed potency against P. aeruginosa ATCC 27853 (MIC = 1.0 µg/mL) while 4 and 7 were selective towards K. pneumoniae ATCC 31488 (MIC = 7.8 and 1.0 µg/mL, respectively). These findings suggest that prenylation of flavonoids may contribute to improving their broad-spectrum antimicrobial activities.

description: Estimating fluid dynamics is classically done through the simulation and integration of numerical models solving the Navier-Stokes equations, which is computationally complex and time-consuming even on high-end hardware. This is a notoriously hard problem to solve, which has recently been addressed with machine learning, in particular graph neural networks (GNN) and variants trained and evaluated on datasets of static objects in static scenes with fixed geometry. We attempt to go beyond existing work in complexity and introduce a new model, method and benchmark. We propose EAGLE, a large-scale dataset of 1.1 million 2D meshes resulting from simulations of unsteady fluid dynamics caused by a moving flow source interacting with nonlinear scene structure, comprised of 600 different scenes of three different types. To perform future forecasting of pressure and velocity on the challenging EAGLE dataset, we introduce a new mesh transformer. It leverages node clustering, graph pooling and global attention to learn long-range dependencies between spatially distant data points without needing a large number of iterations, as existing GNN methods do. We show that our transformer outperforms state-of-the-art performance on, both, existing synthetic and real datasets and on EAGLE. Finally, we highlight that our approach learns to attend to airflow, integrating complex information in a single iteration.

description: Soil infertility constraints and low soil pH are the predominant problems to barley production and productivity in the highland regions of Ethiopia. In reaction to this, the experimentation was carried out in highland areas with low soil pH, on the effects of split application of lime on soil pH and grain yield of barley from 2018 to 2020 for three cropping years. Six treatments were used for this experiment such as control (no inputs); 200 kg ha-1 of NPKSZnB + 94 kg ha-1 of urea top-dressed; lime applied at once (7.6 t ha-1); two splits or 50% (1st and 2nd years); three splits or 33% (1st, 2nd and 3rd years); two splits or 50% (1st and 3rd years). The RCBD design was employed with three replications to arrange treatments. The result of soil analysis after lime application revealed that it improve available phosphorus and concentration of soil pH, and decreased exchangeable acidity compared to before application of lime and control treatments. Among the treatments, splits of lime application (1st and 3rd years) gave the maximum grain yield (3061.5 kg ha-1) of barley meaningfully, whereas the minimum yield was obtained from the control (untreated plot). The maximum grain yields in the third year were obtained from the application of two splits or 50% (1st and 3rd years) were statistically non-significant with the application of three splits or 33% in each year (1st, 2nd and 3rd years) and two splits or 50% (1st and 2nd years). To enhance soil fertility status and obtaining increased barley grain yield, farmers must undertake the use of a split application of lime with chemical fertilizer rather than sole application of inorganic fertilizer for barley production on strongly acidic soil. It suggested that, depending on the accessibility of lime and affordability of barley producers, farmers in the study area could use the above application frequencies with recommended inorganic fertilizer (69N and 46P2O5).

Gluon distributions from Oliveira-Martin-Ryskin combined BFKL+DGLAP evolution equations

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Kwiecinski, Martin, Stasto [13] argue for inclusion of DGLAP terms into BFKL evolution of unintegrated gluon density. The equation was reformulated by Oliveira, Martin, Ryskin [6] employing the opening angle θ = k/xp as the evolution variable. It leads to a description of a θ-integrated gluon density. This paper is a numerical study of these two similar combined BFKL+DGLAP formulations. It is a demonstration of feasibility of the new approach. The different ways of subtracting the contribution common for BFKL and DGLAP proposed in [13] and [6] are compared. The numerical tests confirm that the θ variable is a more natural evolution variable for this kind of equation.

description: We aimed to evaluate the neuroprotective effect of H. sibthorpioides against monosodium-glutamate (MSG) induced excitoneurotoxicity in rats. We randomly divided the animals into 11 groups (n = 8) and subjected them to high doses of MSG (2 g/kg body weight) and the test dose (1 week). The test chemicals were H. sibthorpioides extracts of petroleum ether, chloroform, methanol, and water. We used Dizocilpine-hydrogen-maleate as a standard and assessed the cognitive property using Morris-water-maze and elevated-plus-maze. After the experimental period, we evaluated the biochemical parameters. We found chloroform and methanolic extracts significantly enhanced the cognitive behaviour of rats compared to control. Biochemical analysis suggested that there was a high level of antioxidants and lower levels of glutamate and proinflammatory cytokines in the cortex and hippocampus. We concluded that chloroform and methanolic extracts of H. sibthorpioides enhanced the level of antioxidants, decreased proinflammatory-cytokines and glutamate in the brain, and thus prevented the monosodium-glutamate-induced-excite-neurotoxicity.

description: The motivation of this paper is to study the natural quiver of an artinian algebra, a new kind of quivers, as a tool independing upon the associated basic algebra. In \cite{Li}, the notion of the natural quiver of an artinian algebra was introduced and then was used to generalize the Gabriel theorem for non-basic artinian algebras splitting over radicals and non-basic finite dimensional algebras with 2-nilpotent radicals via pseudo path algebras and generalized path algebras respectively. In this paper, firstly we consider the relationship between the natural quiver and the ordinary quiver of a finite dimensional algebra. Secondly, the generalized Gabriel theorem is obtained for radical-graded artinian algebras. Moreover, Gabriel-type algebras are introduced to outline those artinian algebras satisfying the generalized Gabriel theorem here and in \cite{Li}. For such algebras, the uniqueness of the related generalized path algebra and quiver holds up to isomorphism in the case when the ideal is admissible. For an artinian algebra, there are two basic algebras, the first is that associated to the algebra itself; the second is that associated to the correspondent generalized path algebra. In the final part, it is shown that for a Gabriel-type artinian algebra, the first basic algebra is a quotient of the second basic algebra. In the end, we give an example of a skew group algebra in which the relation between the natural quiver and the ordinary quiver is discussed.

description: Remote sensing consists in measuring some characteristics of an object from a distance. A key example of remote sensing is the Earth observation from sensors mounted on satellites that is a crucial aspect of space programs. The first satellite used for Earth observation was Explorer VII. It has been followed by thousands of satellites, many of which are still working. Due to the availability of a large number of different sensors and the subsequent huge amount of data collected, the idea of obtaining improved products by means of fusion algorithms is becoming more intriguing. Data fusion is often exploited for indicating the process of integrating multiple data and knowledge related to the same real-world scene into a consistent, accurate, and useful representation. This term is very generic and it includes different levels of fusion. This dissertation is focused on the low level data fusion, which consists in combining several sources of raw data. In this field, one of the most relevant scientific application is surely the Pansharpening. Pansharpening refers to the fusion of a panchromatic image (a single band that covers the visible and near infrared spectrum) and a multispectral/hyperspectral image (tens/hundreds bands) acquired on the same area.

description: Considering a cluster of different hierarchical order with various barrier or cadre levels and steps within levels, there is no availability of a structural framework to help exclusively analyze, formulate, identify, differentiate, and design standardized provisional values to cluster members at various barrier levels and steps within levels. This study designs stepwise analysis, generation, and applications of Kifilideen’s Matrix Structural Framework for an infinite term of increasing members of successive levels with the first level having one member of Kifilideen’s Generalized Matrix Progression Sequence. The values of members of the cluster were designed and developed for Kifilideen’s Generalized Matrix Progression Sequence of the infinite term of increasing members of successive levels with the first level having one member and Kifilideen’s Structural Framework was generated for the clusters of such sequence. This Kifilideen’s Matrix Structural Framework also helps to generate Kifilideen’s formulas to identify members and assign values and grades of values to each member within and across levels of Kifilideen’s Matrix Structural Framework. Applications of Kifilideen’s formulas established for Kifilideen’s Generalized Matrix Progression Sequence of the infinite term was carried out. Kifilideen’s Matrix Structural Framework generated some help to exclusively differentiate varying members in the clusters into various levels and steps within levels.

description: We report on a magneto-Raman scattering study of graphene flakes located on the surface of a bulk graphite substrate. By spatially mapping the Raman scattering response of the surface of bulk graphite with an applied magnetic field, we pinpoint specific locations which show the electronic excitation spectrum of graphene. We present the characteristic Raman scattering signatures of these specific locations. We show that such flakes can be superimposed with another flake and still exhibit a graphene-like excitation spectrum. Two different excitation laser energies (514.5 and 720 nm) are used to investigate the excitation wavelength dependence of the electronic Raman scattering signal.

description: The magnetic response is a state-defining property of superconductors. The magnetic flux penetrates type-II bulk superconductors by forming quantum vortices when the enclosed magnetic flux is equal to the magnetic flux quantum. The flux quantum is the universal quantity that depends only on the ratio of fundamental constants: the electron charge and the Planck constant. This work investigates the vortex state in the hole-overdoped Ba$_{1-x}$K$_x$Fe$_2$As$_2$ by using scanning superconducting quantum interference device (SQUID) magnetometry. We observed quantum vortices that carry only a fraction of the flux quantum, which vary continuously with temperature. This finding establishes the phenomenon that superconductors support quantum vortices with non-universally quantized magnetic flux. Furthermore, the demonstrations of the mobility of the fractional vortices and the manipulability of their positions open up a route for future fluxonics applications.

description: Pimenta pseudocaryophyllus (Gomes) Landrum is a Brazilian native plant. The mechanisms by which it promotes analgesia are unknown. We demonstrated the analgesic effect of P. pseudocaryophyllus dried extract (3 mg/kg; i.p.) in the following models of inflammatory pain (maximal inhibition): phenyl-p-benzoquinone (89%), formalin (72% - 1st phase and 96% - 2nd phase for flinches, and 50% - 1st phase and 71% - 2nd phase for licking behavior), complete Freund’s adjuvant (95% - flinches and 33% - licking behavior), and carrageenin (56% - mechanical and 85% - thermal hyperalgesia) without motor impairment. Its analgesic effect depends on inhibiting neutrophil recruitment (95% - histopathology, 83% - myeloperoxidase activity, and 80% - LysM-eGFP mice), oxidative stress (86% - GSH and 98% - superoxide anion), and cytokine production (35% - IL-33, 80% - TNF-α, and 95% - IL-1β). The present study advances in understanding the analgesic mechanisms of P. pseudocaryophyllus.

description: We study the non-relativistic limit of quantum fields for an inertial and a non-inertial observer. We show that non-relativistic particle states appear as a superposition of relativistic and non-relativistic particles in different frames. Hence, the non-relativistic limit is frame-dependent. We detail this result when the non-inertial observer has uniform constant acceleration. Only for low accelerations, the accelerated observer agrees with the inertial frame about the non-relativistic nature of particles locally. In such a quasi-inertial regime, both observers agree about the number of particles describing quantum field states. The same does not occur when the acceleration is arbitrarily large (e.g., the Unruh effect). We furthermore prove that wave functions of particles in the inertial and the quasi-inertial frame are identical up to the coordinate transformation relating the two frames.

description: Hydrides represent the first steps of interstellar chemistry. Sulfanylium (SH$^+$), in particular, is a key tracer of energetic processes. We used ALMA and the IRAM 30 m telescope to search for the lowest frequency rotational lines of SH$^+$ toward the Orion Bar, the prototypical photo-dissociation region illuminated by a strong UV radiation field. On the basis of previous $Herschel$/HIFI observations of SH$^+$, we expected to detect emission of the two SH$^+$ hyperfine structure (HFS) components of the $N_J = 1_0 - 0_1$ fine structure (FS) component near 346 GHz. While we did not observe any lines at the frequencies predicted from laboratory data, we detected two emission lines, each $\sim$15 MHz above the SH$^+$ predictions and with relative intensities and HFS splitting expected for SH$^+$. The rest frequencies of the two newly detected lines are more compatible with the remainder of the SH$^+$ laboratory data than the single line measured in the laboratory near 346 GHz and previously attributed to SH$^+$. Therefore, we assign these new features to the two SH$^+$ HFS components of the $N_J = 1_0 - 0_1$ FS component and re-determine its spectroscopic parameters, which will be useful for future observations of SH$^+$, in particular if its lowest frequency FS components are studied. Our observations demonstrate the suitability of these lines for SH$^+$ searches at frequencies easily accessible from the ground.

description: Context. Plaskett's star (HD47129) is a very massive O-star binary in a post Roche-lobe overflow stage. CoRoT observations of this system revealed photometric variability with a number of frequencies. Aims. The aim of this paper is to characterize the variations in spectroscopy and investigate their origin. Methods. To sample its short-term variability, HD47129 was intensively monitored during two spectroscopic campaigns of six nights each. The spectra were disentangled and Fourier analyses were performed to determine possible periodicities and to investigate the wavelength dependence of the phase constant and the amplitude of the periodicities. Results. Complex line profile variations are observed. Frequencies near 1.65, 0.82, and 0.37 d^-1 are detected consistently in the He i 4471, He ii 4542, and N iii 4510-4518 lines. These frequencies are consistent with those of the strongest signals detected in photometry. The possibilities that these variations stem from pulsations, a recently detected magnetic field or tidal interactions are discussed. Conclusions. Whilst all three scenarios have their strengths, none of them can currently account for all the observed properties of the line profile variations.

description: Radio-loud quasars at high redshift (z > 4) are rare objects in the Universe and rarely observed with Very Long Baseline Interferometry (VLBI). But some of them have flux density sufficiently high for monitoring of their apparent position. The instability of the astrometric positions could be linked to the astrophysical process in the jetted active galactic nuclei in the early Universe. Regular observations of the high-redshift quasars are used for estimating their apparent proper motion over several years. We have undertaken regular VLBI observations of several high-redshift quasars at 2.3 GHz (S band) and 8.4 GHz (X band) with a network of five radio telescopes: 40-m Yebes (Spain), 25-m Sheshan (China), and three 32-m telescopes of the Quasar VLBI Network (Russia) -- Svetloe, Zelenchukskaya, and Badary. Additional facilities joined this network occasionally. The sources have also been observed in three sessions with the European VLBI Network (EVN) in 2018--2019 and one Long Baseline Array (LBA) experiment in 2018. In addition, several experiments conducted with the Very Long Baseline Array (VLBA) in 2017--2018were used to improve the time sampling and the statistics. Based on these 37 astrometric VLBI experiments between 2017 and 2021, we estimated the apparent proper motions of four quasars: 0901+697, 1428+422, 1508+572, and 2101+600.
An invariance principle for a class of non-ballistic random walks in random environment

description: We are concerned with random walks on $\mathbb{Z}^d$, $d\geq 3$, in an i.i.d. random environment with transition probabilities $ε$-close to those of simple random walk. We assume that the environment is balanced in one fixed coordinate direction, and invariant under reflection in the coordinate hyperplanes. The invariance condition was used in Baur and Bolthausen (2014) as a weaker replacement of isotropy to study exit distributions. We obtain precise results on mean sojourn times in large balls and prove a quenched invariance principle, showing that for almost all environments, the random walk converges under diffusive rescaling to a Brownian motion with a deterministic (diagonal) diffusion matrix. We also give a concrete description of the diffusion matrix. Our work extends the results of Lawler (1982), where it is assumed that the environment is balanced in all coordinate directions.

Room temperature spin thermoelectrics in metallic films

description: Considering metallic films at room temperature, we present the first theoretical study of the spin Nernst and thermal Edelstein effects which takes into account dynamical spin-orbit coupling, i.e., direct spin-orbit coupling with the vibrating lattice (phonons) and impurities. This gives rise to two novel processes, namely a dynamical Elliott-Yafet spin relaxation and a dynamical side-jump mechanism. Both are the high-temperature counterparts of the well-known $T = 0$ Elliott-Yafet and side-jump, central to the current understanding of the spin Hall, spin Nernst and Edelstein effects at low $T$. We consider the experimentally relevant regime $T > T_D$, with $T_D$ the Debye temperature, as the latter is lower than room temperature in transition metals such as Pt, Au and Ta typically employed in spin injection/extraction experiments. We show that the interplay between intrinsic (Bychkov-Rashba type) and extrinsic (dynamical) spin-orbit coupling yields a nonlinear $T$- dependence of the spin Nernst and spin Hall conductivities.

description: The present study investigated the cardioprotection of Indole-3-carbinol on isoproterenol (ISO)-induced myocardial infarction in Wistar rats. I3C treatment significantly reduced the prolongation of the QRS complex, QT interval, and ST-segment elevation. I3C was also able to normalise blood pressure (SBP, DBP, and MAP) and HR. I3C significantly decreased heart weight, cardiac troponin I (cTn I), CK-MB, LDH, AST and ALT. I3C ameliorated acute hyperglycaemia, hyperlipidemia, and myocardial infarction (%) in ISO rats. I3C treatment significantly elevated the antioxidant enzymes like SOD, CAT, and GSH and attenuated the MDA levels. I3C reduced the inflammatory cytokines (TNF-α and IL-6) and increased the anti-inflammatory cytokine 1 L-10. Furthermore, I3C significantly recovered myocardial structure by inhibiting neutrophil infiltration and oedema. Moreover, I3C attenuated apoptotic markers (cytochrome C, caspase 9 and caspase 3). Consequently, I3C restored cardiac function in MI rats by alleviating oxidative stress, inflammation, and apoptosis, and I3C could be used to treat myocardial infarction.

description: The phytochemical investigation of the DCM/MeOH (1:1) extract of the fruits of Cnestis ferruginea led to the isolation and characterization of one new quinic acid derivative, ferruginoic acid (1), together with six known compounds 2–7. Compounds 3–7 were reported for the first time from this species. The structures of compounds 1–7 were elucidated on the basis of 1 D and 2 D NMR spectroscopic data, mass spectrometry and by comparison of spectroscopic data with those from the literature. The anticholinesterase (AChE and BChE) activity and DPPH free radical scavenging assay of compounds 1, 3, 4 and 7 were evaluated. Ferruginoic acid (1) exhibited moderate anticholinesterase activity with IC50 value of 36.18 ± 1.78 µg/mL against AChE. Compounds 3, 4 and 7 showed high activity against free radical (DPPH•) scavenging assay (DPPH) with IC50 values 40.09 ± 0.96 µg/mL, 61.70 ± 0.78 µg/mL and 41.87 ± 0.62 µg/mL respectively. These results indicate that C. ferruginea and its constituents could be employed in the management of Alzheimer’s disease.

description: We introduce a method for solving the "inverse" phase equilibria problem: How should the interactions among a collection of molecular species be designed in order to achieve a target phase diagram? Using techniques from convex optimization theory, we show how to solve this problem for phase diagrams containing a large number of components and many coexisting phases with prescribed compositions. We apply our approach to commonly used mean-field models of multicomponent fluids and then use molecular simulations to verify that the designed interactions result in the target phase diagrams. Our approach enables the rational design of "programmable" fluids, such as biopolymer and colloidal mixtures, with complex phase behavior.
