description: We present an exposure-time calculator (ETC) for the Immersion Grating Infrared Spectrograph (IGRINS). The signal and noise values are calculated by taking into account the telluric background emission and absorption, the emission and transmission of the telescope and instrument optics, and the dark current and read noise of the infrared detector arrays. For the atmospheric transmission, we apply models based on the amount of precipitable water vapor along the line of sight to the target. The ETC produces the expected signal-to-noise ratio (S/N) for each resolution element, given the exposure-time and number of exposures. In this paper, we compare the simulated continuum S/N for the early-type star HD 124683 and the late-type star GSS 32, and the simulated emission line S/N for the H2 rovibrational transitions from the Iris Nebula NGC 7023 with the observed IGRINS spectra. The simulated S/N from the ETC is overestimated by 40-50% for the sample continuum targets.

description: We experimentally investigate the distribution of the non-equilibrium work done by an external force on a mesoscopic system with many coupled degrees of freedom: a colloidal monolayer mechanically driven across a periodic light field. Since this system mimics the spatiotemporal dynamics of a crystalline surface moving on a corrugated substrate, our results show general properties of the non-equilibrium work distribution of atomically flat surfaces undergoing friction. We address the role of several parameters which can influence the shape of the work distribution, e.g. the number of particles used to locally probe the system and the time interval to measure the work. We find that, when tuning the control parameters to induce particle depinning from the substrate, there is an abrupt change of the shape of the work distribution. While in the completely static and sliding friction regimes the work distribution is Gaussian, non-Gaussian tails show up due to the spatiotemporal heterogeneity of the particle dynamics during the transition between these two regimes.

description: Radio astronomy is currently thriving with new large ground-based radio telescopes coming online in preparation for the upcoming Square Kilometre Array (SKA). Facilities like LOFAR, MeerKAT/SKA, ASKAP/SKA, and the future SKA-LOW bring tremendous sensitivity in time and frequency, improved angular resolution, and also high-rate data streams that need to be processed. They enable advanced studies of radio transients, volatile by nature, that can be detected or missed in the data. These transients are markers of high-energy accelerations of electrons and manifest in a wide range of temporal scales. Usually studied with dynamic spectroscopy of time series analysis, there is a motivation to search for such sources in large interferometric datasets. This requires efficient and robust signal reconstruction algorithms. To correctly account for the temporal dependency of the data, we improve the classical image deconvolution inverse problem by adding the temporal dependency in the reconstruction problem. Then, we introduce two novel neural network architectures that can do both spatial and temporal modeling of the data and the instrumental response. Then, we simulate representative time-dependent image cubes of point source distributions and realistic telescope pointings of MeerKAT to generate toy models to build the training, validation, and test datasets. Finally, based on the test data, we evaluate the source profile reconstruction performance of the proposed methods and classical image deconvolution algorithm CLEAN applied frame-by-frame. In the presence of increasing noise level in data frame, the proposed methods display a high level of robustness compared to frame-by-frame imaging with CLEAN. The deconvolved image cubes bring a factor of 3 improvement in fidelity of the recovered temporal profiles and a factor of 2 improvement in background denoising.

description: Two-view knowledge graphs (KGs) jointly represent two components: an ontology view for abstract and commonsense concepts, and an instance view for specific entities that are instantiated from ontological concepts. As such, these KGs contain heterogeneous structures that are hierarchical, from the ontology-view, and cyclical, from the instance-view. Despite these various structures in KGs, most recent works on embedding KGs assume that the entire KG belongs to only one of the two views but not both simultaneously. For works that seek to put both views of the KG together, the instance and ontology views are assumed to belong to the same geometric space, such as all nodes embedded in the same Euclidean space or non-Euclidean product space, an assumption no longer reasonable for two-view KGs where different portions of the graph exhibit different structures. To address this issue, we define and construct a dual-geometric space embedding model (DGS) that models two-view KGs using a complex non-Euclidean geometric space, by embedding different portions of the KG in different geometric spaces. DGS utilizes the spherical space, hyperbolic space, and their intersecting space in a unified framework for learning embeddings. Furthermore, for the spherical space, we propose novel closed spherical space operators that directly operate in the spherical space without the need for mapping to an approximate tangent space. Experiments on public datasets show that DGS significantly outperforms previous state-of-the-art baseline models on KG completion tasks, demonstrating its ability to better model heterogeneous structures in KGs.

description: We leverage the Open Research Knowledge Graph - a scholarly infrastructure that supports the creation, curation, and reuse of structured, semantic scholarly knowledge - and present an approach for persistent identification of FAIR scholarly knowledge. We propose a DOI-based persistent identification of ORKG Papers, which are machine-actionable descriptions of the essential information published in scholarly articles. This enables the citability of FAIR scholarly knowledge and its discovery in global scholarly communication infrastructures (e.g., DataCite, OpenAIRE, and ORCID). While publishing, the state of the ORKG Paper is saved and cannot be further edited. To allow for updating published versions, ORKG supports creating new versions, which are linked in provenance chains. We demonstrate the linking of FAIR scholarly knowledge with digital artefacts (articles), agents (researchers) and other objects (organizations). We persistently identify FAIR scholarly knowledge (namely, ORKG Papers and ORKG Comparisons as collections of ORKG Papers) by leveraging DataCite services. Given the existing interoperability between DataCite, Crossref, OpenAIRE and ORCID, sharing metadata with DataCite ensures global findability of FAIR scholarly knowledge in scholarly communication infrastructures.

description: The synthesis and characterisation of p-t-butylcalix[4]arene functionalised at the lower rim with four tetrazole moieties is reported. The macrocycle is found to be a poorer ionophore for lanthanoid cations than the bis-tetrazole–substituted analogue. Solution-phase photophysical studies strongly suggested that the cations interacted only weakly with the calixarene ligand. A mixed sodium/triethylammonium salt of the calixarene ligand was crystallised in the presence of lanthanoid cations and structurally characterised. Strong intramolecular interactions are hypothesised to be the cause of the observed behaviour.

description: Herein, we report a series of 1D, 2D and 3D coordination polymers formed from di-2-pyrazinylmethane (dpzm) and silver(I) salts in which we examine the role the non-coordinating methylene hinge plays in distorting these structures away from those observed for related pyrazine containing coordination polymers. {[Ag2(dpzm)(NO3)2]}n (1) is a 1D ladder-like structure, {[Ag(dpzm)]SO3CF3}n (2) is a 44 connected 2D network and {[Ag2(dpzm)3](X)2}n (X = ClO4, 4a; X = PF6, 4b), {[Ag4(dpzm)5](BF4)4}n (5) and {[Ag3(dpzm)4](SbF6)3}n (6) have pseudo-cubic lattices with some connections between Ag(I) centres missing; this is a consequence of the pyrazine in some cases only acting as a monodentate group (4) or a low ligand:Ag ratio in 5 and 6. Most of the structures compare well to previously reported 1D, 2D and 3D assemblies formed with pyrazine, although an evident feature of dpzm coordination was the geometrical restriction of the methylene hinge, which was apparent in the long Ag–N bond lengths observed for the 3D materials.

description: In this article, we report the synthesis and characterisation of five ligands L1–L5 containing the 2-(pyrazol-1-yl)-benzimidazole chelating group, and investigate their structural chemistry when reacted with either Cu(II) or Zn(II) ions. The mononuclear complexes [Zn(L1)2(NO3)]NO3, 1 and [Cu(L2)2(NO3)]NO3, 2, display similar metal coordination environments although their intermolecular interactions differ through the presence or absence of a benzimidazole N-H group, which allows intermolecular hydrogen bonding to occur in 1, while complex 2 associates purely through π–π interactions. The crystal structure of the dinuclear complex {[Cu2(L3)2(OH2)2]4(ClO4)·PhMe·2MeCN·2H2O}, 3, reveals a series of cyclic units containing internal cavities, within which reside disordered toluene molecules, and which align to form one-dimensional solvent channels throughout the crystal lattice. The structure of the related complex {[Cu2(L4)2(NO3)2]2(NO3)·MeCN}, 4 consists of dimeric units of similar formulation to that of 3, but it contains no internal cavity, and shows a reversal of the relative metal–nitrogen bond length trend observed for the other complexes, due to the steric strain imposed by the backbone group. The structure of complex {[Cu2(L5)2(OH2)2]4(BF4)·0.5(C9H12)}, 5 shows that it forms similar cyclic dimers to those observed in 3, which align throughout the crystal lattice to form much larger (ca. 1 nm diameter) solvent channels.

description: We consider the combined effects that overshooting and the $^{12}$C($α$, $γ$)$^{16}$O reaction rate have on variable white dwarf stellar models. We find that carbon-oxygen white dwarf models continue to yield pulsation signatures of the current experimental $^{12}$C($α$, $γ$)$^{16}$O reaction rate probability distribution function when overshooting is included in the evolution. These signatures hold because the resonating mantle region, encompassing $\simeq$\,0.2\,\Msun\ in a typical $\simeq$\,0.6\,\Msun\ white dwarf model, still undergoes radiative helium burning during the evolution to a white dwarf. Our specific models show two potential low-order adiabatic g-modes, $g_2$ and $g_6$, that signalize the $^{12}$C($α$, $γ$)$^{16}$O reaction rate probability distribution function. Both g-mode signatures induce average relative period shifts of $ΔP/P = 0.44 \%$ and $ΔP/P = 1.33\%$ for $g_2$ and $g_6$ respectively. We find that $g_6$ is a trapped mode, and the $g_2$ period signature is inversely proportional to the $^{12}$C($α$, $γ$)$^{16}$O reaction rate. The $g_6$ period signature generally separates the slower and faster reaction rates, and has a maximum relative period shift of $ΔP/P = 3.45\%$. We conclude that low-order g-mode periods from carbon-oxygen white dwarfs may still serve as viable probes for the $^{12}$C($α$, $γ$)$^{16}$O reaction rate probability distribution function when overshooting is included in the evolution.

description: We study the experimental signatures of top flavored dark matter (top FDM) in direct detection searches and at the LHC. We show that for a dark matter mass above 200 GeV, top FDM can be consistent with current bounds from direct detection experiments and relic abundance constraints. We also show that next generation direct detection experiments will be able to exclude the entire perturbative parameter region for top FDM. For regions of parameter space where the flavor partners of top FDM are not readily produced, the LHC signatures of top FDM are similar to those of other models previously studied in the literature. For the case when the flavor partners are produced at the LHC, we study their impact on a search based on transverse mass variables and find that they diminish the signal significance. However, when the DM flavor partners are split in mass by less than 120-130 GeV, the LHC phenomenology becomes very distinctive through the appearance of displaced vertices. We also propose a strategy by which all parameters of the underlying model can be experimentally determined when the flavor partners can be observed.

description: A series of peptide-functionalised perylene imide molecules was studied to examine the effect of peptide chirality on the self-assembly of the perylene imides core into nanofibres. Peptide stereogenic positions, stereochemical configurations, amphiphilic substitution and perylene core modification were spectroscopically evaluated with respect to chiral assembly. For dipeptide molecules, stereocenters in peptide residue positions proximal to the perylene core (1–5 units) were found to impart helical chirality to the perylene core, while stereocenters in more distal residue positions did not exert a chiral influence. Diastereomers involving stereocenter inversions within the proximal residues consequently manifested spectroscopically as pseudo-enantiomers. Increased side-chain steric demand in the proximal positions gave similar chiral influence but exhibited diminished Cotton effect intensity with additional longer wavelength features attributed to interchain excimers. Replacing one of the two peptide substituents with an alkyl chain to create strongly amphiphilic perylene bisimides disrupted chiral self-assembly. On the other hand, amphiphilic structures achieved through the modification of the perylene imide core with a bisester moiety prompted strongly exciton-coupled, solvent-responsive self-assembly into long, chiral nanofilaments.

description: Mass-transfer interactions in binary stars can lead to accretion disk formation, mass loss from the system and spin-up of the accretor. To determine the trajectory of the mass-transfer stream, and whether it directly impacts the accretor, or forms an accretion disk, requires numerical simulations. The mass-transfer stream is approximately ballistic, and analytic approximations based on such trajectories are used in many binary population synthesis codes as well as in detailed stellar evolution codes. We use binary population synthesis to explore the conditions under which mass transfer takes place. We then solve the reduced three-body equations to compute the trajectory of a particle in the stream for systems with varying system mass ratio, donor synchronicity and initial stream velocity. Our results show that on average both more mass and more time is spent during mass transfer from a sub-synchronous donor than from a synchronous donor. Moreover, we find that at low initial stream velocity the asynchronous rotation of the donor leads to self-accretion over a large range of mass ratios, especially for super-synchronous donors. The stream (self-)intersects in a narrow region of parameter space where it transitions between accreting onto the donor or the accretor. Increasing the initial stream velocity leads to larger areas of the parameter space where the stream accretes onto the accretor, but also more (self-)intersection. The radii of closest approach generally increase, but the range of specific angular momenta that these trajectories carry at the radius of closest approach gets broader. Our results are made publicly available.

description: We demonstrate a method to create arbitrary intensity distributions of multiple wavelengths of light, which can be useful for ultracold atom experiments, by using regional phase-calculation algorithms to find a single hologram which is illuminated with overlapped laser beams. The regionality of the algorithms is used to program spatially distinct features in the calculated intensity distribution, which then overlap in the Fourier plane due to the dependence of diffraction angle on wavelength. This technique is easily integrated into cold atom experiments, requiring little optical access. We demonstrate the method and two possible experimental scenarios by generating light patterns with 670nm, 780nm and 1064nm laser light which are accurate to the level of a few percent.

description: Apart from the assumption that the inflation started at an infinite time in the past, the more realistic initial state of the quantum fluctuations is described by a mixed quantum state imposed at a finite value of the initial time. One of the most important non-trivial vacua is the $α$-vacuum, which is specified by a momentum cutoff $Λ$ \cite{Danielsson:2002kx}. As a consequence, the initial condition is imposed at different initial times for the different $k$-modes. This modifies the amplitude of the quantum fluctuations, and thus the corresponding power spectra. In this paper, we consider the imprint of the $α$-vacuum state on the power spectrum of scalar perturbations in a generic $f(R)$ gravity by assuming an ultraviolet cutoff $Λ$. As a specific model, we consider the Starobinsky model and find the trans-Planckian power spectrum. We find that the leading order corrections to the scalar power spectra in $f(R)$ gravity have an oscillatory behavior as in general relativity \cite{Lim}, and furthermore, the results are in sufficient agreement with the $Λ$CDM model.

description: In their paper titled "On $F$-inverse covers of inverse monoids", Auinger and Szendrei have shown that every finite inverse monoid has an $F$-inverse cover if and only if each finite graph admits a locally finite group variety with a certain property. We study this property and prove that the class of graphs for which a given group variety has the required property is closed downwards in the minor ordering, and can therefore be described by forbidden minors. We find these forbidden minors for all varieties of Abelian groups, thus describing the graphs for which such a group variety satisfies the above mentioned condition.

description: Major advances in X-ray sources including the development of circularly polarized and orbital angular momentum pulses make it possible to probe matter chirality at unprecedented energy regimes and with Angström and femtosecond spatiotemporal resolutions. We survey the theory of stationary and time-resolved nonlinear chiral measurements that can be carried out in the X-ray regime using tabletop X-ray sources or large scale (XFEL, synchrotron) facilities. A variety of possible signals and their information content are surveyed.

description: Surface damage caused by ionizing radiation in SiO$_2$ passivated silicon particle detectors consists mainly of the accumulation of a positively charged layer along with trapped-oxide-charge and interface traps inside the oxide and close to the Si/SiO$_2$-interface. High density positive interface net charge can be detrimental to the operation of a multi-channel $n$-on-$p$ sensor since the inversion layer generated under the Si/SiO$_2$-interface can cause loss of position resolution by creating a conduction channel between the electrodes. In the investigation of the radiation-induced accumulation of oxide charge and interface traps, a capacitance-voltage characterization study of n/$γ$- and $γ$-irradiated Metal-Oxide-Semiconductor (MOS) capacitors showed that close agreement between measurement and simulation were possible when oxide charge density was complemented by both acceptor- and donor-type deep interface traps with densities comparable to the oxide charges. Corresponding inter-strip resistance simulations of a $n$-on-$p$ sensor with the tuned oxide charge density and interface traps show close agreement with experimental results. The beneficial impact of radiation-induced accumulation of deep interface traps on inter-electrode isolation may be considered in the optimization of the processing parameters of isolation implants on $n$-on-$p$ sensors for the extreme radiation environments.

description: The increasing use of life cycle analysis (LCA) methods in order to estimate environmental and social impacts of food products enhances a better understanding of how agricultural production systems contribute to their territories’ environmental and social quality in a positive or negative way. However, the contribution of agriculture to landscape quality and living environment within these territories is never included although some agricultural practices, such as urban pastures, may generate significant landscape amenities that may be valued by locals. From a series of surveys within the Nantes Métropole territory and relying on the study-case of the Vache nantaise, we provide a set of indicators to measure the living environment dimension into future impact analysis. We show how the development of a local urban meat branch involving pastures may contribute to the living environment through inhabitants’ experience, branch sustainability and territorial sustainability.

description: A new tetrapyridine ligand, 5,5′-(3-pyridyl)-2,2′-bipyridine (2) was prepared from 5,5′-dibromo-2,2′-bipyridine (1) via Pd(0)-mediated Suzuki coupling. The reaction was performed either directly upon the free ligand, or upon its Ru(II) complex. The structures of [Ru(1)3](PF6)2 and [Ru(2)3](PF6)2 were studied in solution by NMR, and in the solid state by single crystal X-ray diffraction. Solution NMR data suggests distorted structures, consistent with the observed slow reactivity of the ligands towards Ru(II) ions, and their reluctance to coordinate to Fe(II) ions. However, solid-state X-ray data indicated little distortion from ideal geometries, suggesting the effect may be more electronic than steric in nature.

description: The reaction of ligands based on 3,6-di(3,5-dimethyl-1H-pyrazol-1-yl)pyridazine having carbocyclic rings fused to the pyridazine ring; 1,4-bis(3,5-dimethylpyrazol-1-yl)-6,7-dihydro-5H-cyclopenta[d]pyridazine (L1), 1,4-bis(3,5-dimethylpyrazol-1-yl)-5,6,7,8-tetrahydrophthalazine (L2) and 7,10-bis(3,5-dimethyl-1H-pyrazol-1-yl)-8,9-diazafluoranthene (L3) with silver triflate gave complexes 1–3. Characterisation of these using single-crystal X-ray structure determination clearly showed that the steric bulk of the carbocycle stops the 3,5-dimethyl-1H-pyrazole from chelating metal atoms. Ligands L1 and L3 were tetrabridging (complexes 1 and 3), while L2 formed a one-dimensional zigzag polymer (complex 2).

description: The currently established electronic phase diagram of cuprates is based on a study of single- and double-layered compounds. These CuO$_2$ planes, however, are directly contacted with dopant layers, thus inevitably disordered with an inhomogeneous electronic state. Here, we solve this issue by investigating a 6-layered Ba$_2$Ca$_5$Cu$_6$O$_{12}$(F,O)$_2$ with inner CuO$_2$ layers, which are clean with the extremely low disorder, by angle-resolved photoemission spectroscopy (ARPES) and quantum oscillation measurements. We find a tiny Fermi pocket with a doping level less than 1% to exhibit well-defined quasiparticle peaks which surprisingly lack the polaronic feature. This provides the first evidence that the slightest amount of carriers is enough to turn a Mott insulating state into a metallic state with long-lived quasiparticles. By tuning hole carriers, we also find an unexpected phase transition from the superconducting to metallic states at 4%. Our results are distinct from the nodal liquid state with polaronic features proposed as an anomaly of the heavily underdoped cuprates.

description: In this thesis, we consider deep neural networks for Machine Learning. We depict neural networks as weighted directed graphs and we represent them as parametric functions that receive an input and compute an output, or prediction, given some fixed parameters, the weights and the biases. The quintessence of a neural network is the feed-forward model, in which the underlying graph does not contain cycles (acyclic graph) and the parametric function is defined in a compositional, or hierarchical, way.
Throughout our presentation, we focus on a supervised learning setting, where our neural network model, or learner, has access to a training set that contains examples of how pairs of input-output data are related. In other words, supervised learning amounts to learning from examples. Given a training set, depending whether the outputs have real or categorical values, we consider regression and logistic regression. For each setting, we provide the basic statistical framework and construct a loss function known as the empirical risk. We train our neural network by minimizing the empirical risk w.r.t. its parameters by using gradient-based optimization methods. The gradient of the loss function is computed via the back-propagation algorithm.
We showcase the convergence and generalization properties of different algorithms (deep neural network models and optimization methods) using real-world data.
