description: Many of the electronic properties of high-temperature cuprate superconductors (HTSC) are strongly dependent on the number of charge carriers put into the CuO$_2$ planes (doping). Superconductivity appears over a dome-shaped region of the doping-temperature phase diagram. The highest critical temperature (Tc) is obtained for the so-called "optimum doping". The doping mechanism is usually chemical; it can be done by cationic substitution. This is the case, for example, in La$_{2-x}$Sr$_x$CuO$_4$ where La3+ is replaced by Sr2+ thus adding a hole to the CuO$_2$ planes. A similar effect is achieved by adding oxygen as in the case of YBa$_2$Cu$_3$O$_{6+δ}$ where $δ$ represents the excess oxygen in the sample. In this paper we report on a different mechanism, one that enables the addition or removal of carriers from the surface of the HTSC. This method utilizes a self-assembled monolayer (SAM) of polar molecules adsorbed on the cuprate surface. In the case of optically active molecules, the polarity of the SAM can be modulated by shining light on the coated surface. This results in a light-induced modulation of the superconducting phase transition of the sample. The ability to control the superconducting transition temperature with the use of SAMs makes these surfaces practical for various devices such as switches and detectors based on high-Tc superconductors.

description: We present new results on the classical T Tauri star RU Lupi based on three observing runs collecting high-resolution spectra, complementary NIR spectra, multicolour photometric data, and X-ray observations. The photospheric absorption lines are weakened. This veiling becomes extremely strong on occasion, and we show that this effect is due to narrow emission lines that fill in the photospheric lines. The blue-shifted wings in the optical emission lines of He I, attributed to a stellar wind, are remarkably stable in equivalent width. In contrast, the red-shifted wings change dramatically in strength depending on rotational phase. From the pattern of variability we infer that these wings originate in accreting gas close to the star, and that the accretion funnels are bent and trail the hot spot. Forbidden emission lines are very stable over the entire observing period and originate in the disk wind. A system of narrow blue-shifted absorption features seen in lines of Ca II and Na I can be traced to a disk wind as well. Slightly blue-shifted emission components are present in the forbidden lines and might be related to a wide angle molecular disk wind.

description: We study spin-glass systems characterized by continuous occurrence of singularities. The theory of Lee-Yang zeros is used to find the singularities. By using the replica method in mean-field systems, we show that two-dimensional distributions of zeros of the partition function in a complex parameter plane are characteristic feature of random systems. The results of several models indicate that the concept of chaos in the spin-glass state is different from that of the replica symmetry breaking. We discuss that a chaotic phase at imaginary temperature is different from the spin-glass phase and is accessible by quantum dynamics in a quenching protocol.

description: We analyze the effects of $δ-$ meson on hypernuclei within the frame-work of relativistic mean field theory. The $δ-$ meson is included into the Lagrangian for hypernuclei. The extra nucleon-meson coupling ($g_δ$) affects the every piece of physical observables, like binding energy, radii and single particle energy of hypernuclei. The lambda mean field potential is investigated which is consistent with other predictions. Flipping of single particle energy levels are observed with the strength of $g_δ$ in the considered hypernuclei as well as normal nuclei. The spin-orbit potentials are observed for considered hypernuclei and the effect of $g_δ$ on spin-orbit potentials is also analyzed. The calculated single-$Λ$ binding energies ($B_Λ$) are quite agreeable with the experimental data.

description: We report on the lasing in air and pure nitrogen gas pumped by a single 800 nm femtosecond laser pulse. Depending on gas pressure, incident laser power and beam convergence, different lasing lines are observed in the forward direction with rapid change of their relative intensities. The lines are attributed to transitions between vibrational and rotational levels of the first negative band of the singly charged nitrogen molecule-ion. We show that self-seeding plays an important role in the observed intensity changes.

description: We present an optical to near-infrared transmission spectrum of the hot Jupiter HAT-P-1b, based on HST observations, covering the spectral regime from 0.29 to 1.027μm with STIS, which is coupled with a recent WFC3 transit (1.087 to 1.687μm). We derive refined physical parameters of the HAT-P-1 system, including an improved orbital ephemeris. The transmission spectrum shows a strong absorption signature shortward of 0.55μm, with a strong blueward slope into the near-ultraviolet. We detect atmospheric sodium absorption at a 3.3σ significance level, but find no evidence for the potassium feature. The red data implies a marginally flat spectrum with a tentative absorption enhancement at wavelength longer than ~0.85μm. The STIS and WFC3 spectra differ significantly in absolute radius level (4.3 +/- 1.6 pressure scale heights), implying strong optical absorption in the atmosphere of HAT-P-1b. The optical to near-infrared difference cannot be explained by stellar activity, as simulta- neous stellar activity monitoring of the G0V HAT-P-1b host star and its identical companion show no significant activity that could explain the result. We compare the complete STIS and WFC3 transmission spectrum with theoretical atmospheric mod- els which include haze, sodium and an extra optical absorber. We find that both an optical absorber and a super-solar sodium to water abundance ratio might be a sce- nario explaining the HAT-P-1b observations. Our results suggest that strong optical absorbers may be a dominant atmospheric feature in some hot Jupiter exoplanets.

description: The main goal of this report is to evaluate the use of container technology in order to streamline the deployment of HPC end-user applications. Each application to be deployed typically has a number of dependencies in terms of supported versions of the OS, compilers and linked libraries, which make the maintenance of the different
installations complex and error prone on typical HPC systems. The implementation of a lightweight virtualization strategy can strongly improve both the management of the HPC systems and the portability of end-user applications to different HPC centres. This report reviews the considerations necessary and the current status of
some of the competing implementations and proposes a suitable architecture relevant to HPC environments.
Dark halos and elliptical galaxies as marginally stable dynamical systems

description: The origin of equilibrium gravitational configurations is sought in terms of the stability of their trajectories, as described by the curvature of their Lagrangian configuration manifold of particle positions --- a context in which subtle spurious effects originating from the singularity in the two body potential become particularly clear. We focus on the case of spherical systems, which support only regular orbits in the collisionless limit, despite the persistence of local exponential instability of $N$-body trajectories in the anomalous case of discrete point particle representation even as $N \rightarrow \infty$. When the singularity in the potential is removed, this apparent contradiction disappears. In the absence of fluctuations, equilibrium configurations generally correspond to positive scalar curvature, and thus support stable trajectories. A null scalar curvature is associated with an effective, averaged, equation of state describing dynamically relaxed equilibria with marginally stable trajectories. The associated configurations are quite similar to those of observed elliptical galaxies and simulated cosmological halos, and are necessarily different from the systems dominated by isothermal cores, expected from entropy maximization in the context of the standard theory of violent relaxation. It is suggested that this is the case because a system starting far from equilibrium does not reach a 'most probable state' via violent relaxation, but that this process comes to an end as the system finds and (settles in) a configuration where it can most efficiently wash out perturbations. We explicitly test this interpretation by means of direct simulations.

description: Image compression is an important filed in image processing. The science welcomes any tinny contribution that may increase the compression ratio by whichever insignificant percentage. Therefore, the essential contribution in this paper is to increase the compression ratio for the well known Portable Network Graphics (PNG) image file format. The contribution starts with converting the original PNG image into k-Modulus Method (k-MM). Practically, taking k equals to ten, and then the pixels in the constructed image will be integers divisible by ten. Since PNG uses Lempel-Ziv compression algorithm, then the ability to reduce file size will increase according to the repetition in pixels in each k-by-k window according to the transformation done by k-MM. Experimental results show that the proposed technique (k-PNG) produces high compression ratio with smaller file size in comparison to the original PNG file.

Negative differential resistance in graphene-nanoribbon/carbon-nanotube crossbars: A first-principles multiterminal quantum transport study

description: We simulate quantum transport between a graphene nanoribbon (GNR) and a single-walled carbon nanotube (CNT) where electrons traverse vacuum gap between them. The GNR covers CNT over a nanoscale region while their relative rotation is 90 degrees, thereby forming a four-terminal crossbar where the bias voltage is applied between CNT and GNR terminals. The CNT and GNR are chosen as either semiconducting (s) or metallic (m) based on whether their two-terminal conductance exhibits a gap as a function of the Fermi energy or not, respectively. We find nonlinear current-voltage (I-V) characteristics in all three investigated devices---mGNR-sCNT, sGNR-sCNT and mGNR-mCNT crossbars---which are asymmetric with respect to changing the bias voltage from positive to negative. Furthermore, the I-V characteristics of mGNR-sCNT crossbar exhibits negative differential resistance (NDR) with low onset voltage $V_\mathrm{NDR} \simeq 0.25$ V and peak-to-valley current ratio $\simeq 2.0$. The overlap region of the crossbars contains only $\simeq 460$ carbon and hydrogen atoms which paves the way for nanoelectronic devices ultrascaled well below the smallest horizontal length scale envisioned by the international technology roadmap for semiconductors. Our analysis is based on the nonequilibrium Green function formalism combined with density functional theory (NEGF-DFT), where we also provide an overview of recent extensions of NEGF-DFT framework (originally developed for two-terminal devices) to multiterminal devices.

description: Since the discovery of room temperature ferromagnetism in (Ti,Co)O2, the mechanism has been under discussion for a decade. Particularly, the central concern has been whether or not the ferromagnetic exchange interaction is mediated by charge carriers like (Ga,Mn)As. Recent two studies on the control of ferromagnetism in anatase (Ti,Co)O2 at room temperature via electric field effect [Y. Yamada et al., Science 332, 1065 (2011)] and chemical doping [Y. Yamada et al., Appl. Phys. Lett. 99, 242502 (2011)] indicate a principal role of electrons in the carrier-mediated exchange interaction. In this article, the authors review fundamental properties of anatase (Ti,Co)O2 and discuss the carrier mediated ferromagnetism.

description: Die Verwendung eines Rheobasenwertes zur Abschätzung einer Frühgeburtsneigung erscheint uns zur Zeit noch nicht ausreichend gesichert. Die Bestimmung der Rheobase ist in jedem Einzelfall mit so vielen Schwierigkeiten verbunden, die Übertragbarkeit einer Erregbarkeit von der Skelettmuskulatur auf die glatte Muskulatur der vegetativ innervierten Organe so wenig theoretisch und empirisch bewiesen, daß wir in dieser Technik keinen wissenschaftlichen Fortschritt erblicken können. Diese Behauptungen werden zur Zeit durch weitere Untersuchungen an Schwangeren überprüft. Die Verwendung eines Rheobasenwertes zur Erkennung einer drohenden Frühgeburt und zur Kontrolle der Effektivität einer tokolytischen Behandlung wird kritisch erörtert. Zahlreiche Erkenntnisse aus elektrodiagnostischen Untersuchungen schränken den Wert dieses Verfahrens in der Geburtshilfe von vornherein ein. Offenkundige Unzulänglichkeiten bei der Rheobasen-Messung, insbesondere mangelnde Reliabilität sowie ein bisher nicht kontrollierter möglicher Versuchsleiter-Effekt mahnen zu einer vorsichtigen Dateninterpretation. Diese kritische Sichtweise wird mit Daten aus eigenen Experimenten illustriert.

description: Educational aspiration plays an important role in terms of both reinforcing and discouraging future academic achievement of students. The present research aimed at assessing the level of educational aspiration of school-going adolescents in selected primary schools of Shashemene town, Ethiopia. Using the survey method, quantitative data were collected by self-administered questionnaires from randomly selected 500 grade 8 students. Data were entered into SPSS version 20 and both descriptive and inferential statistical techniques were used for data presentation. It was found that 97.5% of respondents reported having planned to directly join secondary schools after completing 8th grade and 85.8% of them aspire to join higher education in the future. Results of correlation statistics revealed that educational aspiration is associated with age and academic performance of students. In addition, coefficients of regression analysis showed that age (0.184, 0.000) and academic performance (0.153, 0.001) of students significantly determine what the students intend to pursue after completing 8th grade under circumstances in which they are free to decide without external influence. Above all, students’ aspiration to join higher educational institutions has been found to be significantly associated with the age (0.168, 0.000) of the students. School-going adolescents in the study area were found to have a very high level of educational aspiration. Converting such potential into an opportunity for Ethiopia’s future development requires family, school, and government institutions to provide the necessary support to the students.

description: In 1899 the American journalist Henry Demarest Lloyd was one of many social reformers who travelled to New Zealand to witness the social programmes instituted by the Liberal government. For Lloyd and other Progressives, New Zealand represented a model industrial democracy. His book Newest England (1900) describes Public Works Department projects built under the direction of the Department’s Minister, Richard Seddon, including the Makōhine Railway Viaduct. This viaduct was significant as the first steel structure built using the cooperative labour system. This paper places Lloyd’s interpretation of the Makōhine Viaduct within the Progressive discourse about design and labour taking place in Chicago around 1900, focusing on the activities of the Chicago Arts and Crafts Society of which Lloyd was a member. Attention to Lloyd’s Newest England reveals a radical plan for the future of industrial society, one that prefigured the technocracy movement of the early twentieth century. In its dedication to the aims of settler colonialism, it also reveals the theme of racial evolution underpinning Progressive visions of the coming industrial democracy. Exploring that theme, the paper expands scholarship on the origins of modern American architecture in Chicago to include the historical context of colonisation and global immigration.

description: We have studied the temperature-pressure phase diagram of CeCoSi by electrical-resistivity experiments under pressure. Our measurements revealed a very unusual phase diagram. While at low pressures no dramatic changes and only a slight shift of the Neél temperature $T_N$ ($\approx 10$ K) are observed, at about 1.45 GPa a sharp and large anomaly, indicative of the opening of a spin-density-wave (SDW) gap, appears at a comparatively high temperature $T_S \approx 38$ K. With further increasing pressure $T_S$ shifts rapidly to low temperatures and disappears at about 2.15 GPa, likely continuously in a quantum critical point, but without evidence for superconductivity. Even more surprisingly, we observed a clear shift of $T_S$ to higher temperatures upon applying a magnetic field. We discuss two possible origins for $T_S$, either magnetic ordering of Co or a meta-orbital type of transition of Ce.

description: Abstract The American economist Thorstein Veblen’s The Theory of the Leisure Class (1899) has been used to support and define concepts of architectural modernity for more than one hundred years. Best known for introducing the concept of “conspicuous consumption,” this influential book has been especially valuable for historians of the architecture of consumer culture. Yet curiously, Veblen’s own architectural examples have escaped scholarly attention. This article explores the link Veblen drew between Gothic Revival architecture and cultural barbarism. Inverting the concepts and terminology of race science, Veblen used the image of the Gothic Revival university to criticize the rhetoric of American exceptionalism. Seen through the lens of Veblen’s writing, Henry Ives Cobb’s design for the University of Chicago (1891–97), where Veblen taught for fourteen years, represents the transformation of leisure-class aesthetics under the logic of capitalism.

description: We investigate the influence of SiO2, Au, Ag, Cu, and Pt substrates on the Raman spectrum of graphene. Experiments reveal particularly strong modifications to the intensity, position, width, and shape of the Raman signal of graphene on platinum, compared to that of suspended graphene. The modifications strongly depend on the relative orientation of the graphene and platinum lattices. These observations are theoretically investigated and shown to originate from hybridization of electronic states in graphene and d-orbitals in platinum. It is expected that, quite generally, hybridization between graphene and any material with d-orbitals near the Fermi level will result in an imprint on the graphene Dirac cone which depends sensitively on the relative orientation of the respective lattices.

description: The collective nature of light interactions with atomic and nuclear ensembles yields the fascinating phenomena of superradiance and radiation trapping. We study the interaction of gamma rays with a coherently vibrating periodic array of two-level nuclei. Such nuclear motion can be generated, e.g., in ionic crystals illuminated by a strong driving optical laser field. We find that deflection of the incident gamma beam into the Bragg angle can be switched on and off by nuclear vibrations on a superradiant time scale determined by the collective nuclear frequency, which is of the order of terahertz. Namely, if the incident gamma wave is detuned from the nuclear transition by much larger frequency it passes through the static nuclear array. However, if the nuclei vibrate with the frequency of the gamma ray detuning then parametric resonance can yield energy transfer into the Bragg deflected beam on the superradiant time scale, which can be used for fast control of gamma rays.

description: We apply a 3+1D viscous hydrodynamic + cascade model to the heavy ion collision reactions with $\sqrt{s_{NN}}=6.3\dots39$ GeV. To accommodate the model for a given collision energy range, the initial conditions for hydrodynamic phase are taken from UrQMD, and the equation of state at finite baryon density is based on Chiral model coupled to the Polyakov loop. We study the collision energy dependence of pion and kaon rapidity distributions and $m_T$-spectra, as well as charged hadron elliptic flow and how shear viscosity affects them. The model calculations are compared to the data for Pb-Pb collisions at CERN SPS, as well as for Au-Au collisions in the Beam Energy Scan (BES) program energies at BNL RHIC. The data favours the value of shear viscosity $η/s\gtrsim0.2$ for this collision energy range.

description: We demonstrate that the supersymmetry is dynamically broken in the four-dimensional SU(N) gauge theory coupled to a strongly-coupled superconformal theory T_N. This is a direct generalization of the model of supersymmetry breaking on deformed moduli space in supersymmetric QCD with an SU(2) gauge group.

Densities, temperatures, pressures, and abundances derived from OII recombination lines in HII regions and their implications

description: Based on high quality observations of multiplet V1 of OII and the NLTE atomic computations of OII we study the density and temperature of a sample of HII regions. We find that the signature for oxygen rich clumps of high density and low temperature is absent in all objects of our sample: one extragalactic and eight Galactic HII regions. The temperatures derived from: a) recombination lines of OII, and b) recombination lines of HI together with Balmer continua are lower than those derived from forbidden lines, while the densities derived from recombination lines of OII are similar or smaller than densities derived from forbidden lines. Electron pressures derived from collisionally excited lines are about two times larger than those derived from recombination lines. These results imply that the proper abundances are those derived from recombination lines and suggest that other processes in addition to direct photoionization, such as dissipation of turbulent energy in shocks, magnetic reconnection, and shadowed regions, might be responsible for the large ADF and t2 values observed in HII regions.

description: Although the growth of social media has changed the way employees communicate at work, our understanding of the related workplace dynamics, particularly in public organizations, is still embryonic. This study fills these research gaps by testing hypotheses, drawn from social cognitive theory and social capital theory, using two sets of data on social media usage patterns and workplace practices among public employees. Our survey data (n = 1,360) analysis revealed that most respondents (more than 72%) spent at least an hour per day on social media while at work, for both work- and non-work-related purposes. Furthermore, public employees with higher levels of social media competence (technical understanding and impact assessment) were more likely to report effective collaboration and seek assistance when needed. The results of scenario-based randomized survey experiment (n = 600) show that the perceived fairness of social media-related termination decisions (or “get dooced”) was influenced by the presence of an explicit workplace social media policy.

description: The fractal dimension of minimal spanning trees on percolation clusters is estimated for dimensions $d$ up to $d=5$. A robust analysis technique is developed for correlated data, as seen in such trees. This should be a robust method suitable for analyzing a wide array of randomly generated fractal structures. The trees analyzed using these techniques are built using a combination of Prim's and Kruskal's algorithms for finding minimal spanning trees. This combination reduces memory usage and allows for simulation of larger systems than would otherwise be possible. The path length fractal dimension $d_{s}$ of MSTs on critical percolation clusters is found to be compatible with the predictions of the perturbation expansion developed by T.S.Jackson and N.Read [T.S.Jackson and N.Read, Phys.\ Rev.\ E \textbf{81}, 021131 (2010)].
Two-particle correlations and balance functions in p-Pb and Pb-Pb collisions at LHC energies with ALICE

description: Recent measurements of two-particle correlations in high-multiplicity p-Pb collisions at $\sqrt{s_{NN}} = 5.02$ TeV revealed a long-range structure (large separation in $Δη$) at the near- ($Δφ\simeq0$) and away-side ($Δφ\simeqπ$) of the trigger particle. At LHC energies, these ridge-like structures have not only been observed in Pb-Pb collisions, but also in high-multiplicity pp collisions. In the first case, this phenomenon is commonly related to collectivity in hadron production, i.e. hydrodynamic evolution, whereas in the latter, mechanisms like longitudinal color connections and multi-parton interactions might play an important role. To shed light on the particle production mechanisms in p-Pb and Pb-Pb collisions and answer the question about collectivity, we extend the two-particle correlation analysis for hadrons in two directions: identified particles, which should show a characteristic pattern in case of collective motion in a hydrodynamic medium, and charge-dependent correlations studied with the balance function, which are sensitive to charge-dependent effects like local charge conservation.

description: No effective therapeutics to treat neurodegenerative diseases exist, despite significant attempts to find drugs that can reduce or rescue the debilitating symptoms of tauopathies such as Alzheimer’s disease, Parkinson’s disease, frontotemporal dementia, amyotrophic lateral sclerosis, or Pick’s disease. A number of in vitro and in vivo models exist for studying neurodegenerative diseases, including cell models employing induced-pluripotent stem cells, cerebral organoids, and animal models of disease. Recent research has focused on microtubule-stabilizing agents, either natural products or synthetic compounds that can prevent the axonal destruction caused by tau protein pathologies. Although promising results have come from animal model studies using brain-penetrant natural product microtubule-stabilizing agents, such as paclitaxel analogs that can access the brain, epothilones B and D, and other synthetic compounds such as davunetide or the triazolopyrimidines, early clinical trials in humans have been disappointing. This review aims to summarize the research that has been carried out in this area and discuss the potential for the future development of an effective microtubule stabilizing drug to treat neurodegenerative disease.
