description: We present a very simple model for the study of charge transport in a molecule patterned on B-DNA. In this model we use a discrete non-linear Schrödinger equation to describe electrons propagating along the sugar-phosphate backbone of the DNA molecule. We find that in this model, for a given nonlinearity, the transport is controlled by $J$, a parameter which relates to the electronic coupling between different molecules on the backbone. For smaller values of $J$ we have localised states while at higher values of $J$ the soliton field is spread out and through its interaction with the lattice it has stronger effects on the distortion of the lattice.

description: In this study we develop a single-station deep-learning approach for fast and reliable estimation of earthquake magnitude directly from raw waveforms. We design a regressor composed of convolutional and recurrent neural networks that is not sensitive to the data normalization, hence waveform amplitude information can be utilized during the training. Our network can predict earthquake magnitudes with an average error close to zero and standard deviation of ~0.2 based on single-station waveforms without instrument response correction. We test the network for both local and duration magnitude scales and show a station-based learning can be an effective approach for improving the performance. The proposed approach has a variety of potential applications from routine earthquake monitoring to early warning systems.
On the discrepancy between two approaches to the equilibrium problem for spinning particles

description: We show that the absence of equilibrium states of two uncharged spinning particles located on the symmetry axis, revealed in an approximate approach recently employed by Bonnor, can be explained by a non-general character of his approximation scheme which lacks an important arbitrary parameter representing a strut. The absence of this parameter introduces an artificial restriction on the particles' angular momenta, making it impossible to find a physical solution to the balance equations.

description: Using an array of coupled microwave resonators arranged in a deformed honeycomb lattice, we experimentally observe the formation of pseudo-Landau levels in the whole crossover from vanishing to large pseudomagnetic field strength. This is achieved by utilizing an adaptable set-up in a geometry that is compatible with the pseudo-Landau levels at all field strengths. The adopted approach enables to observe fully formed flat-band pseudo-Landau levels spectrally as sharp peaks in the photonic density of states, and image the associated wavefunctions spatially, where we provide clear evidence for a characteristic nodal structure reflecting the previously elusive supersymmetry in the underlying low-energy theory. In particular, we resolve the full sublattice polarization of the anomalous 0th pseudo-Landau level, which reveals a deep connection to zigzag edge states in the unstrained case.

description: The WG 5 committee, at its meeting in Delft, May 2005, decided to include co-arrays in the next Fortran Standard. A Fortran program containing co-arrays is interpreted as if it were replicated a fixed number of times and all copies were executed asynchronously. Each copy has its own set of data objects and is called an image. The array syntax of Fortran is extended with additional trailing subscripts in square brackets to give a clear and straightforward representation of access to data on other images. The paper does not atempt to describe the full details of the feature as it now appears in the draft of the new standard. Instead, we describe a subset and demonstrate the use of this subset with examples.
Phase coherence in tight-binding models with nonrandom long-range hopping

description: The density of states, even for a perfectly ordered tight-binding model, can exhibit a tail-like feature at the top of the band, provided the hopping integral falls off in space slowly enough. We apply the coherent potential approximation to study the eigenstates of a tight-binding Hamiltonian with uncorrelated diagonal disorder and long-range hopping, falling off as a power $μ$ of the intersite distance. For a certain interval of hopping range exponent $μ$, we show that the phase coherence length is infinite for the outermost state of the tail, irrespectively of the strength of disorder. Such anomalous feature can be explained by the smallness of the phase-space volume for the disorder scattering from this state. As an application of the theory, we mention that ballistic regime can be realized for Frenkel excitons in two-dimensional molecular aggregates, affecting to a large extent the optical response and energy transport.

description: In order to study the stress sensitivity of tight sand reservoir and evaluate their impact on the productivity, physical and mathematical simulation is carried out under the scanning electron microscopy (SEM), the casting thin sections and the stress sensitivity test technology. The results show that porosity and permeability decreases with pressure, the damage mode of porosity and the permeability can be described as “Falling quickly then falling slowly.” The relative loss rate of porosity is from 4.88% to 8.46%, meanwhile, permeability has stronger stress sensitivity and the relative loss rate of permeability is from 63.86% to 86.14%. The porosity stress sensitivity is connected with the microscopic pore structure, pore size and rock particles compressive capacity, and permeability is mainly affected by the pore distribution and pore size distribution. A productivity equation of tight reservoir in which the stress sensitivity of the porosity and permeability is considered shows that as the reservoir properties become worse, the stronger the rock sensitivity, the higher the degree of impact on the production. This study provides reference for reducing sensitivity damage in tight sandstone reservoirs and improving gas recovery.

description: One of the goals of the Aktienführer-Datenarchiv project is to process data from the Aktienführer and
store it in a structured manner in a database. The Aktienführer is a reference work published annually between 1956-1999 as print book comprising data for companies listed at stock exchanges in Germany.
A high character recognition accuracy is crucial for structure recognition and further analyses of the OCR-output.
To optimize the OCR quality, "Ocromore" was developed.
It is a toolset for combining multiple OCR-outputs.
The best combined result is achieved with an word-wise character confidence-based multi sequence alignment (msa) approach. Our results show an character accuracy increase of 0,49% and an error reduction of 33% compared to the best single result.

description: Water samples from the different basins of the Baltic Sea and North Sea were collected during four cruises taken place in 2016–2017. Altogether 60 water samples for 3H activity concentration and 120 water samples for stable isotopes ratio (δ18O and δ2H) were analysed. Exceptionally strong inflow activity from North Sea to the Baltic Sea occurred prior our surveys. The data obtained enabled comprehensive evaluation of tritium and stable isotopes distribution in waters of Baltic Sea and contributing inputs, including riverine and atmospheric freshwater flux and saline water inflow through the Danish Straits. By comparing with the previous studies, we noticed a tendency toward an increase in the δ18O and δ2H values of zero-salinity component over time, which may be due to climate change. In the case of tritium, the influence of artificial sources has also been noticed.

description: Nonequilibrium states of a nanoscopic system may be achieved by both applying a bias voltage $V$ to its contacts and producing a difference $ΔT$ in their temperatures. Then the total current results from two competing flows, induced by $V$ and $ΔT$, respectively. Here we explore finite frequency quantum noise of this thermoelectric current flowing through a quantum dot whose low-energy dynamics is governed by Majorana degrees of freedom. We demonstrate that at finite frequency $ω$ Majorana zero modes induce a perfect universal symmetry between photon emission and absorption spectra and produce universal thermoelectric resonances in their frequency dependence in contrast to non-Majorana quantum noise which is either asymmetric or non-universal. In particular, at low temperatures the differential thermoelectric quantum noise induced by Majorana zero modes shows resonances with a nontrivial maximum $\frac{e^3}{h}\log(2^{1/4})$ at $ω=\mp\frac{|eV|}{\hbar}$ when $k_\text{B}ΔT\ll|eV|$. Our results challenge cutting-edge experiments using quantum noise detectors to reveal the universal spectral symmetry and resonant structure of the Majorana thermoelectric finite frequency quantum noise.

description: We study the critical Casimir interaction between two spherical colloids immersed in a binary liquid mixture close to its critical demixing point. The surface of each colloid prefers one species of the mixture with the exception of a circular patch of arbitrary size, where the other species is preferred. For such objects we calculate, within the Derjaguin approximation, the scaling function describing the critical Casimir potential, and we use it to derive the scaling functions for all components of the forces and torques acting on both colloids. The results are compared with available experimental data. Moreover, the general relation between the scaling function for the potential and the scaling functions for the force and the torque is derived.

description: The study of ages, helium mass fraction (Y) and chemical composition of globular clusters in dwarf galaxies is important for understanding the physical conditions at the main evolutionary stages of the host galaxies and for constraining the build-up histories of large galaxies. We present the analysis of integrated-light spectra of 8 extragalactic and 20 Galactic globular clusters (GCs) using our population synthesis method. We calculate synthetic spectra of GCs according to the defined stellar mass functions using model atmospheres and stellar parameters ($[Fe/H]$, $T_{eff}$, and $log g$) set by theoretical isochrones. The main advantage of our method is the ability to determine not only chemical composition but also the age and mean Y in a cluster by modelling and analysis of Balmer absorption lines. The knowledge of Y and anomalies of light elements in star clusters is one of the key points for understanding the phenomenon of multiple stellar populations.

description: Spam, also known as Unsolicited Commercial Email (UCE), is the bane of email communication. Many data mining researchers have addressed the problem of detecting spam, generally by treating it as a static text classification problem. True in vivo spam filtering has characteristics that make it a rich and challenging domain for data mining. Indeed, real-world datasets with these characteristics are typically difficult to acquire and to share. This paper demonstrates some of these characteristics and argues that researchers should pursue in vivo spam filtering as an accessible domain for investigating them.

description: Cryptocurrencies represent one of the most attractive markets for financial speculation. As a consequence, they have attracted unprecedented attention on social media. Besides genuine discussions and legitimate investment initiatives, several deceptive activities have flourished. In this work, we chart the online cryptocurrency landscape across multiple platforms. To reach our goal, we collected a large dataset, composed of more than 50M messages published by almost 7M users on Twitter, Telegram and Discord, over three months. We performed bot detection on Twitter accounts sharing invite links to Telegram and Discord channels, and we discovered that more than 56% of them were bots or suspended accounts. Then, we applied topic modeling techniques to Telegram and Discord messages, unveiling two different deception schemes - "pump-and-dump" and "Ponzi" - and identifying the channels involved in these frauds. Whereas on Discord we found a negligible level of deception, on Telegram we retrieved 296 channels involved in pump-and-dump and 432 involved in Ponzi schemes, accounting for a striking 20% of the total. Moreover, we observed that 93% of the invite links shared by Twitter bots point to Telegram pump-and-dump channels, shedding light on a little-known social bot activity. Charting the landscape of online cryptocurrency manipulation can inform actionable policies to fight such abuse.

description: Aims. Our goal is to find the relation between the two-point correlation functions (CFs) of projected and spatial density fields of galaxies in the context of the cosmic web. Methods. To investigate relations between spatial (3D) and projected (2D) CFs of galaxies we used density fields of two simulations: a $Λ$-dominated cold dark matter (LCDM) model with known particle data, and the Millennium simulation with know data on simulated galaxies. We compare 3D and 2D correlation functions. In the 2D case, we use samples of various thickness to find the dependence of 2D CFs on the thickness of samples. We also compare 3D CFs in real and redshift space. Results. The dominant elements of the cosmic web are clusters and filaments, separated by voids filling most of the volume. In individual 2D sheets, the positions of clusters and filaments do not coincide. As a result, in projection, the clusters and filaments fill in 2D voids. This leads to a decrease in the amplitudes of CFs (and power spectra) in projection. For this reason, the amplitudes of 2D CFs are lower than the amplitudes of 3D correlation functions: the thicker the 2D sample, the greater the difference. Conclusions. Spatial CFs of galaxies contain valuable information about the geometrical properties of the cosmic web that cannot be found from projected CFs.

description: Three new hasubanan-type alkaloids, stephalonine Q (1), stephalonine R (2) and stephalonine S (3), together with four known alkaloids, isolonganone (4), eletefine (5), aurantiamide (6), N-cinnamoyltyramine (7), were isolated from the whole plant of Stephania longa. Their structures were identified by NMR, HR-ESI-MS, CD methods and x-ray crystallography, as well as by comparison with the literature data. All isolated compounds were evaluated for their antimicrobial activities against five bacteria in vitro. Compound 5 displayed inhibitory activity against only S. aureus, with an MIC value of 50 μg/mL.

description: We compare and contrast the entanglement in the ground state of two Jahn-Teller models. The $E\otimesβ$ system models the coupling of a two-level electronic system, or qubit, to a single oscillator mode, while the $E\otimesε$ models the qubit coupled to two independent, degenerate oscillator modes. In the absence of a transverse magnetic field applied to the qubit, both systems exhibit a degenerate ground state. Whereas there always exists a completely separable ground state in the $E\otimesβ$ system, the ground states of the $E\otimesε$ model always exhibit entanglement. For the $E\otimesβ$ case we aim to clarify results from previous work, alluding to a link between the ground state entanglement characteristics and a bifurcation of a fixed point in the classical analogue. In the $E\otimesε$ case we make use of an ansatz for the ground state. We compare this ansatz to exact numerical calculations and use it to investigate how the entanglement is shared between the three system degrees of freedom.

description: We obtain Gaussian upper and lower bounds on the transition density q_t(x,y) of the continuous time simple random walk on a supercritical percolation cluster C_{\infty} in the Euclidean lattice. The bounds, analogous to Aronsen's bounds for uniformly elliptic divergence form diffusions, hold with constants c_i depending only on p (the percolation probability) and d. The irregular nature of the medium means that the bound for q_t(x,\cdot) holds only for t\ge S_x(ω), where the constant S_x(ω) depends on the percolation configuration ω.

description: Charge reversal of the planar electrical double layer is studied by means of a well known integral equations theory. By a numerical analysis, a diagram is constructed with the onset points of charge reversal in the space of the fundamental variables of the system. Within this diagram two regimes of charge reversal are identified, referred to as oscillatory and non oscillatory. We found that these two regimes can be distinguished through a simple formula. Furthermore, a symmetry between electrostatic and size correlations in charge reversal is exhibited. The agreement of our results with other theories and molecular simulations data is discussed.

Deep learning velocity signals allows to quantify turbulence intensity

description: Turbulence, the ubiquitous and chaotic state of fluid motions, is characterized by strong and statistically non-trivial fluctuations of the velocity field, over a wide range of length- and time-scales, and it can be quantitatively described only in terms of statistical averages. Strong non-stationarities hinder the possibility to achieve statistical convergence, making it impossible to define the turbulence intensity and, in particular, its basic dimensionless estimator, the Reynolds number. Here we show that by employing Deep Neural Networks (DNN) we can accurately estimate the Reynolds number within $15\%$ accuracy, from a statistical sample as small as two large-scale eddy-turnover times. In contrast, physics-based statistical estimators are limited by the rate of convergence of the central limit theorem, and provide, for the same statistical sample, an error at least $100$ times larger. Our findings open up new perspectives in the possibility to quantitatively define and, therefore, study highly non-stationary turbulent flows as ordinarily found in nature as well as in industrial processes.

description: Galaxies grow through the accretion of gas, minor mergers and major mergers in the hierarchical picture of galaxy evolution. The merging of two gas-rich galaxies cause gas to be driven towards the centres of the individual galaxies producing intense circum-nuclear star formation and creating a fuel reservoir for the accretion onto the central blackhole. Feedback due to supernova winds or AGN (Active Galactic Nuclei) accretion blows out the surrounding gas through an outflow at later merger stages, that may be large enough to deplete the galaxies of their fuel reservoir and hence shut down star formation and starve the central black hole. It is still uncertain what the impact of outflows is on merging galaxies, and when in the merging process they are most significant. This thesis has used Integral Field Spectroscopy (IFS) observations of merging galaxies to probe the impact of outflows on gas-rich major mergers. Using velocity-resolved absorption and emission lines arising from the interstellar medium of the galaxies, this thesis shows that the occurrence of outflows increases with merger stage and also that these outflows are not caused by the same physical processes, such as star formation or an AGN, in each merger system. This thesis describes the machine learning algorithm created to expedite the decision making process of multi-component emission line fitting for studies of ionised gas in large IFS surveys. The remainder of the research outlined in this thesis has identified a number of new facts about merging galaxies that are important for further research in this field including the following; Composite galaxies are being incorrectly classed as the same type of galaxy when they can range in excitation mechanisms; Composite galaxies are not the same between different morphologies, including between merging galaxies and isolated galaxies; The outflow from the northern nucleus of the merging system IRAS F10257- 4339 can be traced in neutral, ionised, and molecular gas, and is most likely caused by starformation; Outflows of neutral gas from galaxies increases with merger stage.

description: Berberine possesses a wide spectrum of lipid regulation, and yet it has poor physicochemical property and cytotoxicity as a drug candidate. In order to alleviate the problems, a total of twenty-one 9-O-cinnamoylberberines and twenty 9-O-cinnamoyltetrahydroberberines were designed, synthesized, and evaluated by in vitro cell viability experiment and four classical lipid-lowering assays involving with total cholesterol, triglyceride, low density lipoprotein cholesterol, and high density lipoprotein cholesterol. A structure–activity relationship study of these compounds resulted in the discovery of two promising candidate molecules (5p and 7u). Compound 5p displayed the most potent inhibitory effect for TG formation, with the inhibitory rates of 40.5% and 76.8% in 3T3-L1 cells and HepG2 cells, respectively. Compound 7u exhibited the most promoting activity for the production of HDLC, with the increasing rates of 52.6% and 70.5% in both models, respectively. These two attractive compounds can be further investigated as new lipid-lowering agents in follow-up researches.

description: To calibrate Fourier analysis of $S_5$ ranking data by Markov chain Monte Carlo techniques, a set of moves (Markov basis) is needed. We calculate this basis, and use it to provide a new statistical analysis of two data sets. The calculation involves a large Gröbner basis computation (45825 generators), but reduction to a minimal basis and reduction by natural symmetries leads to a remarkably small basis (14 elements). Although the Gröbner basis calculation is infeasible for $S_6$, we exploit the symmetry of the problem to calculate a Markov basis for $S_6$ with 7,113,390 elements in 58 symmetry classes. We improve a bound on the degree of the generators for a Markov basis for $S_n$ and conjecture that this ideal is generated in degree 3.

description: Sesleria juncifolia Host (1809: 13), nom. illeg., non Suffren (1802: 113)
 Lectotype (designated here): — CROATIA. Split-Dalmatia: Biokovo, 3 May, Host 113 (W1885-0002432!). Fig. 3. Image available at: http://herbarium.univie.ac.at/database/detail.php? ID =256624
 Other original material examined:— [Icon] Tab. 22 (Host 1809).
 Notes:—The name S. juncifolia was proposed by Host (1809) to describe plants from Dalmatia (“ in rupestribus Dalmatiae ”). The protologue includes a detailed morphological description, iconography (“ Tab. 22 ”), a description of the geographical area in which the specimen was collected (Dalmatia), and the species' habitat (cliffs). Among Host’s collections deposited in W (see Foggi et al. 2004) there is a single herbarium gathering of S. juncifolia (W 1885-0002432) reporting the site of collection as “ Biocovo ”, a locality in the central Dalmatia area. This gathering bears four plant fragments, which probably belong to a single S. juncifolia individual, whose features match Host’s diagnosis. Corresponding in both morphological characters and collection locality, this specimen represents original material for the name Sesleria juncifolia. Having at disposal both a specimen and an illustration, we choose the specimen as the lectotype for this name.
 Sesleria juncifolia Host (1809) is a later homonym of Sesleria juncifolia Suffren (1802) and is therefore illegitimate (Art. 53.1, McNeill et al. 2012). According to Deyl (1946), S. juncifolia Host is a synonym of S. tenuifolia Schrader (Deyl's annotation " Sesleria tenuifolia " is also present on the lectotype; Fig. 3), whereas according to Alegro (2007), S. juncifolia Host is a synonym of S. interrupta Visiani.
