description: All commercial electron spin polarimeters work in single channel mode, which is the bottleneck of researches by spin-resolved photoelectron spectroscopy. By adopting the time inversion antisymmetry of magnetic field, we developed a multichannel spin polarimeter based on normal incident VLEED. The key point to achieve the multi-channel measurements is the spatial resolution of the electron optics. The test of the electron optics shows that the designed spatial resolution can be achieved and an image type spin polarimeter with 100 times 100, totally ten thousand channels is possible to be realized.

description: New cycloartane, 22-hydroxy-25-hydroperoxycycloart-23E-en-3-one (1), along with six known analogues (2–7) and three steroids (8–10), were isolated from the leaves of Trichilia casaretti. Structures were elucidated mainly on the basis of the analysis of 1D and 2D NMR (1H and 13C) and HRESIMS spectroscopic data, involving comparison with data of the literature. The cytotoxic activities of 1–7 and 10 isolated compounds were also evaluated against human leukemia cell line Molt-4 (acute lymphoblastic) and exhibited good cytotoxic activity with IC50 values ranging from 10.62 to 21.14 μM.

description: We examine the unitarity of a class of generalized Maxwell U(1) gauge theories in (2+1) D containing the pseudodifferential operator $\Box^{1-α}$, for $α\in [0,1)$. We show that only Quantum Electrodynamics (QED$_3$) and its generalization known as Pseudo Quantum Electrodynamics (PQED), for which $α=0$ and $α= 1/2$, respectively, satisfy unitarity. The latter plays an important role in the description of the electromagnetic interactions of charged particles confined to a plane, such as in graphene or in hetero-junctions displaying the quantum Hall effect.

description: Uniquely in Cu2OSeO3, the Skyrmions, which are topologically protected magnetic spin vortex-like objects, display a magnetoelectric coupling and can be manipulated by externally applied electric (E) fields. Here, we explore the E-field coupling to the magnetoelectric Skyrmion lattice phase, and study the response using neutron scattering. Giant E-field induced rotations of the Skyrmion lattice are achieved that span a range of $\sim$25$^{\circ}$. Supporting calculations show that an E-field-induced Skyrmion distortion lies behind the lattice rotation. Overall, we present a new approach to Skyrmion control that makes no use of spin-transfer torques due to currents of either electrons or magnons.

description: We present an efficient polarizable electrostatic model based on direct polarization, SMIRNOFF specification, and bond charge corrections method for improved electrostatics in molecular dynamics (MD) simulations. We developed software to derive electrostatic parameters from quantum mechanical (QM) calculations and benchmarked our model on calculations of gas-phase and condensed-phase properties. Benchmark results show good agreements with reference values, in particular providing critical corrections to dielectric constants of nonpolar organic liquids. This result suggests that our model is a good starting point for developing a general and affordable polarizable force field for biomolecular simulations.

description: We propose a few-body quantum phenomenon, which manifests itself through stochastic state preparations and measurements followed by a conditioned post-processing procedure. We show two experimental protocols to implement these phenomena with existing quantum computers, and examine their feasibility by using simulations.

description: We investigate electric-field induced redshifts of photoluminescence from individual single-walled carbon nanotubes. The shifts scale quadratically with field, while measurements with different excitation powers and energies show that effects from heating and relaxation pathways are small. We attribute the shifts to the Stark effect, and characterize nanotubes with different chiralities. By taking into account exciton binding energies for air-suspended tubes, we find that theoretical predictions are in quantitative agreement.

description: The naturally occurring compound andrographolide 1 was used as a substrate for the synthesis of a novel terminal alkyne 3 which on copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction with azides 4a-l, 7 and 9 furnished a series of regioselective andrographolide triazolyl conjugates 5a-l, 8 and 10, respectively. A free glycoconjugate 6 was also prepared by selective deprotection of compound 5i in good yield. All the compounds were characterized by absorbance, FT-IR, NMR, and HR-MS analyses. The triazolyl conjugate 8 was further investigated as a probe for selective detection of Fe3+ ion in matrix. The mode of attachment of Fe3+ ion to the compound 8 was established by absorbance, fluorescence, infrared (IR), and nuclear magnetic resonance (NMR) spectroscopy, and high resolution mass-spectrometry (HR-MS). The logic gate circuits were constructed for the probe 8 and ethylenediaminetetraacetic acid (EDTA). The environmental perspective of probe 8 was investigated in real water samples.

description: The environment plays an increasingly important role for human health and efficient linkage with environmental and earth observation data is crucial to quantify human exposures. Currently, there are no harmonized metadata standards for automatic mapping. This project aims to facilitate the linkage of data of different research fields by generating and enriching interoperable and machine-readable metadata for exemplary data of our three domains Health (HMGU), Earth & Environment (UFZ), and Aeronautics, Space & Transport (DLR) and by mapping these metadata so that they can be jointly queried, searched and integrated into HMC.
After reviewing several standards, strategies and tools, we developed an approach to align our metadata to a common structure and format. We identified spatial and time coverage as the main mapping criteria. For the environmental metadata and the epidemiological metadata that have a spatial component (study centers, recruitment districts) we converged to the standard ISO 19115 and to the eXtensible Markup Language (XML). 
Additionally for the health domain, we reviewed several metadata standards for health data but currently available standards were set up mostly for medical or clinical data. Thus, they only fit our epidemiological cohort data in a very limited way. Nevertheless, we started to standardize and enrich the metadata of the LISA birth cohort study by supplementing more than 15,000 variables with Maelstrom categories and subcategories. Of these, approximately 900 entries include an ICD-10 code. 
Moreover, we compiled a decision matrix to guide the selection of a suitable application to upload and store the harmonized metadata. Building on this conceptual work, we identified a catalog (GeoNetwork) to store a subset of our cross-domain metadata and set up a test instance on a HMGU server and uploaded the first metadata. 
We are currently populating the mapping platform with further metadata and testing the full functionality of the tool, especially the filtering and search tools options of the application to enable the intended mapping. By the end of the project, we plan to release the platform to HMC and other researchers working in thematically related fields.

description: A new oxazole-type compound (1), named macrooxazole E, and three known macrooxazoles A-C (2–4), were isolated from ethyl acetate (EtOAc) extracts of Phoma sp. JS0228 cultures, an endophytic fungus of Morus alba (M. alba). Structures of the isolated compounds were determined using spectroscopic methods, such as 1 D- and 2 D-nuclear magnetic resonance (NMR) and high-resolution mass spectrometry (HRMS). Macrooxazole E (1) differed from macrooxazole C only in the presence of methyl carboxylate instead of free carboxylic acid. Macrooxazole C showed moderate anti-proliferative activities against human breast cancer (MCF-7) and prostate cancer (LNCaP) cell lines with IC50 values of 0.29 mM and 0.36 mM, respectively. This study presents the possibility of the endophytic fungus Phoma sp. JS0228 to produce new bioactive natural compounds.

Constructing sampling and measurement error models for ICOADS SST from ships based on ESA CCI SST analysis
Creators: name: Kaplan, Alexey
Publisher: name: Zenodo
Year: 2022

description: Short abstract Taking advantage of high resolution, reliable uncertainty estimates, and in situ data independence of daily fields of the European Space Agency (ESA) Climate Change Initiative (CCI) SST Analysis product (hereinafter, CCI SST), versions 1, errors of 1ox1o monthly bin averages of ship SST observations from International Comprehensive Ocean-Atmosphere Data Set (ICOADS), Release 3.0, were modelled as a sum of random effects, once their systematic biases were approximated and removed as their climatologically-averaged differences from similarly binned CCI SST. For 1992-2010 period, in more than 66% (50%) of locations with temporal coverage exceeding 50%(66%) for 1ox1o monthly bins containing more than one observation, the error magnitude agrees within 20%(10%) with the estimates, based on the random error model. These error estimates were also split into sampling and measurement error components. Seasonal variations in the total error magnitude were traced to the sampling error component, which is driven by seasonal changes in the intra-bin SST variability, while the seasonality of measurement error estimates appears not significant (by Levene’s test for variance). Random measurement error estimates for different measurement methods used on ICOADS ships compared well with previously published estimates. Improved error estimates were constructed by recombining all-season measurement error estimates with sampling error estimates based on the full data sample from the CCI SST data set.

description: By applying complementary analytic and numerical methods, we investigate the dynamics of spin-$1/2$ XXZ models with variable-range interactions in arbitrary dimensions. The dynamics we consider is initiated from uncorrelated states that are easily prepared in experiments, and can be equivalently viewed as either Ramsey spectroscopy or a quantum quench. Our primary focus is the dynamical emergence of correlations and entanglement in these far-from-equilibrium interacting quantum systems: we characterize these correlations by the entanglement entropy, concurrence, and squeezing, which are inequivalent measures of entanglement corresponding to different quantum resources. In one spatial dimension, we show that the time evolution of correlation functions manifests a non-perturbative dynamic singularity. This singularity is characterized by a universal power-law exponent that is insensitive to small perturbations. Explicit realizations of these models in current experiments using polar molecules, trapped ions, Rydberg atoms, magnetic atoms, and alkaline-earth and alkali atoms in optical lattices, along with the relative merits and limitations of these different systems, are discussed.

description: New emerging technologies powered by Artificial Intelligence (AI) have the potential to disruptively transform our societies for the better. In particular, data-driven learning approaches (i.e., Machine Learning (ML)) have been a true revolution in the advancement of multiple technologies in various application domains. But at the same time there is growing concern about certain intrinsic characteristics of these methodologies that carry potential risks to both safety and fundamental rights. Although there are mechanisms in the adoption process to minimize these risks (e.g., safety regulations), these do not exclude the possibility of harm occurring, and if this happens, victims should be able to seek compensation. Liability regimes will therefore play a key role in ensuring basic protection for victims using or interacting with these systems. However, the same characteristics that make AI systems inherently risky, such as lack of causality, opacity, unpredictability or their self and continuous learning capabilities, may lead to considerable difficulties when it comes to proving causation. This paper presents three case studies, as well as the methodology to reach them, that illustrate these difficulties. Specifically, we address the cases of cleaning robots, delivery drones and robots in education. The outcome of the proposed analysis suggests the need to revise liability regimes to alleviate the burden of proof on victims in cases involving AI technologies.

description: We perform a numerical analysis of superfluid turbulence produced by thermal counterflow in He II by using the vortex filament model. Counterflow in a low aspect ratio channel is known to show the transition from laminar flow to the two turbulent states TI and TII. The present understanding is that the TI has the turbulent superfluid and the laminar normal fluid but both fluids are turbulent in the TII state. This work studies the vortex tangle in the TI state. Solid boundary condition is applied to walls of a square channel, and the velocity field of the normal fluid is prescribed to be a laminar Poiseuille profile. An inhomogeneous vortex tangle, which concentrates near the solid boundaries, is obtained as the statistically steady state. It is sustained by its characteristic space-time oscillation. The inhomogeneity of the vortex tangle shows the characteristic dependence on temperature, which is caused by two competitive effects, namely the profile of the counterflow velocity and the mutual friction.

A 3-dimensional model of tangential YORP

description: Tangential YORP, or TYORP, has recently been demonstrated to be an important factor in the evolution of an asteroid's rotation state. It is complementary to normal YORP, or NYORP, which used to be considered previously. While NYORP is produced by non-symmetry in the large-scale geometry of an asteroid, TYORP is due to heat conductivity in stones on the surface of the asteroid. Yet to date TYORP has been studied only in a simplified 1-dimensional model, substituting stones by high long walls. This article for the first time considers TYORP in a realistic 3-dimensional model, also including shadowing and self-illumination effects via ray tracing. TYORP is simulated for spherical stones lying on regolith. The model includes only 5 free parameters, and the dependence of the TYORP on each of them is studied. The TYORP torque appears to be smaller than previous estimates from 1-dimensional model, but still comparable to the NYORP torques. These results can be used to estimate TYORP of different asteroids, and also as a basis for more sophisticated models of TYORP.

description: The present research paper is an investigation of dark energy nature of logarithmic $f(R, T)$-gravity cosmology in a flat FLRW space-time universe. We have derived modified Einstein's field equations for the function $f(R, T)=R-16πGα\ln(T)$ where $R$ is the Ricci scalar curvature, $T$ is the trace of the stress energy momentum tensor and $α$ is a model parameter. We have solved field equations in the form of two fluid scenario as perfect-fluid and dark-fluid, where dark fluid term is derived in the form of perfect fluid source. We have made an observational constraints on the cosmological parameters $Ω_{(m)}, ω^{(de)}$ and $H_{0}$ using $χ^{2}$ test with observational datasets like Pantheon sample of SNe Ia and $H(z)$. With these constraints we have discussed our model with deceleration parameter $q$, energy parameters $Ω_{(m)}, Ω_{(de)}$, EoS parameter $ω^{(de)}$ etc. Also, we have done Om diagnostic analysis. The derived $f(R, T)$ model shows a quintessence dark energy model $ω^{(de)}>-1$ and late-time universe approaches to $Λ$CDM model.

description: We have calculated the pulsations of massive stars using a nonlinear hydrodynamic code including time-dependent convection. The basic structure models are based on a standard grid published by Meynet et al. (1994). Using the basic structure, we calculated envelope models, which include the outer few percent of the star. These models go down to depths of at least 2 million K. These models, which range from 40 to 85 solar masses, show a range of pulsation behaviours. We find models with very long period pulsations ( $>$ 100 d), resulting in high amplitude changes in the surface properties. We also find a few models that show outburst-like behaviour. The details of this behaviour are discussed, including calculations of the resulting wind mass-loss rates.

description: An enhancement of localized nonlinear modes in coupled systems gives rise to a novel type of escape process. We study a spatially one dimensional set-up consisting of a linearly coupled oscillator chain of $N$ mass-points situated in a metastable nonlinear potential. The Hamilton-dynamics exhibits breather solutions as a result of modulational instability of the phonon states. These breathers localize energy by freezing other parts of the chain. Eventually this localised part of the chain grows in amplitude until it overcomes the critical elongation characterized by the transition state. Doing so, the breathers ignite an escape by pulling the remaining chain over the barrier. Even if the formation of singular breathers is insufficient for an escape, coalescence of moving breathers can result in the required concentration of energy. Compared to a chain system with linear damping and thermal fluctuations the breathers help the chain to overcome the barriers faster in the case of low damping. With larger damping, the decreasing life time of the breathers effectively inhibits the escape process.

description: We present Finite Volume methods for diffusion equations on generic meshes, that received important coverage in the last decade or so. After introducing the main ideas and construction principles of the methods, we review some literature results, focusing on two important properties of schemes (discrete versions of well-known properties of the continuous equation): coercivity and minimum-maximum principles. Coercivity ensures the stability of the method as well as its convergence under assumptions compatible with real-world applications, whereas minimum-maximum principles are crucial in case of strong anisotropy to obtain physically meaningful approximate solutions.

description: Purpose: Amateur singing is a universal, accessible, and enjoyable musical activity that may have positive impacts on human communication. However, evidence of an impact of singing on speech articulation is still scarce, yet understanding the effects of vocal training on speech production could provide a model for treating people with speech deficits. The aim of this study was to examine speech production in younger and older adults with or without amateur singing experience.Method: Thirty-eight amateur singers (aged 20–87 years, 23 women and 15 men) and 40 nonmusician active controls (aged 23–88 years, 19 women and 21 men) were recruited. A set of tasks were used to evaluate the oral motor sphere: two voice production tasks, a passage reading task, and a modified diadochokinetic (DDK) rates task performed at a natural rhythm and as quickly as possible.Results: Our results show that older age was associated with lower reading rate, lower articulation rate, and articulation rate variability in the DDK task, as well as reduced accuracy for the phonologically complex stimuli. Most importantly, our results show an advantage for singers over cognitively active nonsingers in terms of articulatory accuracy in the most challenging situations.Conclusion: This result suggests extended maximal performance capacities in amateur singers perhaps resulting from the articulatory efforts required during singing.Supplemental Material S1.

description: In this work we investigate the thermodynamical properties and modified dynamics of black hole solutions in the semiclassical regime of affine coherent state quantization. Using the weak correspondence principle we build a semiclassical effective action that we use to study thermodynamics in the canonical ensemble and to compare classical analytical solutions with the corresponding semiclassical ones. We determine a strong compatibility of these affine black holes with the thermodynamical properties of the classical counterparts, with only minor restrictions on the free parameters of the models. Furthermore we obtain that black hole singularities are removed by quantum effects, resulting also in a modified extension of the horizon, in agreement with the sign of entropy corrections.

description: A series of N-heteroaryl substituted Gallamide derivatives 3a-3g were synthesised and the obtained structures were further confirmed by different spectral studies. For in-vitro antibacterial activity, the synthesised compounds were evaluated against three UTI (Urinary Tract Infection) bacterial strains including Staphylococcus aureus, Escherichia coli, and Streptococcus pyogenes. Furthermore, the designed compounds were docked with bacterial DNA gyrase and dihydropteroate synthase. All the compounds had shown good inhibition against S. aureus whereas compound 3e has produced significant inhibition at 28 and 26 mm against S.aureus and E.coli, respectively. The MIC value of the conjugate 3e and 3d was 3.12 and 6.25 μg/mL against S. aureus andE.coli, respectively. Compound 3,4,5-trihydroxy-N-(4-(N-(5-methyl isoxazol-3-yl) sulfamoyl) phenyl)benzamide 3d had shown the highest binding energy against both the targets along with good antibacterial action.

description: We study how rapid rotation influences the relation between the normalized moment of inertia $\bar{I}$ and quadrupole moment $\bar{Q}$ for scalarized neutron stars. The questions one has to answer are whether the EOS universality is preserved in this regime and what are the deviations from general relativity. Our results show that the $\bar{I}-\bar{Q}$ relation is nearly EOS independent for scalarized rapidly rotating stars, but the differences with pure Einstein's theory increase compared to the slowly rotating case. In general, smaller negative values of the scalar field coupling parameters $β$ lead to larger deviations, but these deviations are below the expected accuracy of the future astrophysical observations if one considers values of $β$ in agreement with the current observational constraint. An important remark is that although the normalized $\bar{I}-\bar{Q}$ relation is quite similar for scalar-tensor theories and general relativity, the unnormalized moment of inertia and quadrupole moment can be very different in the two theories. This demonstrates that although the $\bar{I}-\bar{Q}$ relations are potentially very useful for some purposes, they might not serve us well when trying to distinguish between different theories of gravity.
