ISNI
Organisational Identifiers

description: Over the last year, the International Standard Name Identifier board have been considering the ways in which ISNI as a system can improve to meet new challenges and become more open and transparent. One particular consideration has been to make ISNIs a better solution for organisation identifiers. The British Library as an ISNI Registration Agency has also been developing tools that make it easier to use for identifying organisations, in response to feedback from national and international collaborators. This session will give PIDapalooza an update on ISNI and British Library activities over the past year and demonstrate how we are working to get a wider buy-in on persistent identification of organisations early on – including how we’re attempting to work with funders to embed PID practice.
Energy transfer using unitary transformations

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We study the unitary time evolution of a simple quantum Hamiltonian describing two harmonic oscillators coupled via a three-level system. The latter acts as an engine transferring energy from one oscillator to the other and is driven in a cyclic manner by time-dependent external fields. The S-matrix of the cycle is obtained in analytic form. The total number of quanta contained in the system is a conserved quantity. As a consequence the spectrum of the S-matrix is purely discrete and the evolution of the system is quasi-periodic.
Spin-polarized voltage probes for helical edge state: a model study

description: Theoretical models of a spin-polarized voltage probe (SPVP) tunnel-coupled to the helical edge states (HES) of a quantum spin Hall system (QSHS) are studied. Our first model of the SPVP comprises $N_{P}$ spin-polarized modes (subprobes), each of which is locally tunnel-coupled to the HES, while the SPVP, as a whole, is subjected to a self-consistency condition ensuring zero average current on the probe. We carry out a numerical analysis which shows that the optimal situation for reading off spin-resolved voltage from the HES depends on the interplay of the probe-edge tunnel-coupling and the number of modes in the probe ($N_P$). We further investigate the stability of our findings by introducing Gaussian fluctuations in {\it{(i)}} the tunnel-coupling between the subprobes and the HES about a chosen average value and {\it{(ii)}} spin-polarization of the subprobes about a chosen direction of the net polarization of SPVP. We also perform a numerical analysis corresponding to the situation where four such SPVPs are implemented in a self-consistent fashion across a ferromagnetic barrier on the HES and demonstrate that this model facilitates the measurements of spin-resolved four-probe voltage drops across the ferromagnetic barrier. As a second model, we employ the edge state of a quantum anomalous Hall state (QAHS) as the SPVP which is tunnel-coupled over an extended region with the HES. A two-dimensional lattice simulation for the quantum transport of the proposed device setup comprising a junction of QSHS and QAHS is considered and a feasibility study of using the edge of the QAHS as an efficient spin-polarized voltage probe is carried out in presence of an optimal strength of the disorder.

description: We explore mechanical properties of top down fabricated, singly clamped inverted conical GaAs nanowires. Combining nanowire lengths of 2-9 $μ$m with foot diameters of 36-935 nm yields fundamental flexural eigenmodes spanning two orders of magnitude from 200 kHz to 42 MHz. We extract a size-independent value of Young's modulus of (45$\pm$3) GPa. With foot diameters down to a few tens of nanometers, the investigated nanowires are promising candidates for ultra-flexible and ultra-sensitive nanomechanical devices.

description: The heterogeneous nature of the European Network of Agroecology Living Labs and Research Infrastructures amplifies the importance of allowing for consolidation processes as a key factor for long-term success. Important consolidation processes include the building of trust in relationships to enable open exchange, the establishment, review and adaptation of network governance, and the evolution of network infrastructure.
Funding programmes need to encourage research into defining network types and their characteristics as these have implications for how a network functions and how it may need to be supported by both policy and practice.

description: Background: Biomaterial-based therapies offer significant potential in regenerative approaches for Parkinson’s disease (PD). For preliminary ex vivo assessment of the efficacy/safety of such approaches, the use of explanted tissue containing the dopaminergic pathways affected by PD provides significant advantages over the use of cell culture models.

Aim: Thus, the aim of this study was to assess the utility of ventral mesencephalic tissue explants for assessment of the efficacy and safety of GDNF or GDF-5 functionalised collagen hydrogels ex vivo.

Methods: For this study, 30 embryonic day 14 rat embryos were dissected to obtain the mesencephalic-diencephalic tube which was maintained in tissue culture using the air media interface method2. Explants were then exposed to 5 µg/µl GDF-5 or GDNF either as a bolus or encapsulated in a collagen hydrogel for various time-points, after which they were fixed for histological analyses. Free floating tyrosine hydroxylase immunohistochemistry was completed to identify survival and development of dopaminergic neurons.

Results: Exposure to the collagen hydrogels did not have any detrimental effects on the explanted tissue viability ex vivo. Moreover, when the hydrogels were functionalised with GDNF or GDF-5, this improved dopaminergic axonal outgrowth from the cells.

Conclusions: This experiment successfully demonstrates the utility of ventral mesencephalic tissue explants for assessment of the efficacy/safety neurotrophin-functionalised collagen hydrogels. This approach offers advantages over cellular models for the preliminary assessment of biomaterial-based regenerative therapies for PD.

Enhancing the sensitivity of the LIGO gravitational wave detector by using squeezed states of light

description: Nearly a century after Einstein first predicted the existence of gravitational waves, a global network of earth-based gravitational wave observatories is seeking to directly detect this faint radiation using precision laser interferometry. Photon shot noise, due to the quantum nature of light, imposes a fundamental limit on the attometer level sensitivity of the kilometer-scale Michelson interferometers deployed for this task. Here we inject squeezed states to improve the performance of one of the detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO) beyond the quantum noise limit, most notably in the frequency region down to 150 Hz, critically important for several astrophysical sources, with no deterioration of performance observed at any frequency. With the injection of squeezed states, this LIGO detector demonstrated the best broadband sensitivity to gravitational waves ever achieved, with important implications for observing the gravitational wave Uni- verse with unprecedented sensitivity.
Multi-stage quantum absorption heat pumps

description: It is well known that heat pumps, while being all limited by the same basic thermodynamic laws, may find realization on systems as "small" and "quantum" as a three-level maser. In order to quantitatively assess how the performance of these devices scales with their size, we design generalized $N$-dimensional ideal heat pumps by merging $N-2$ elementary three-level stages. We set them to operate in the absorption chiller mode between given hot and cold baths, and study their maximum achievable cooling power and the corresponding efficiency as a function of $N$. While the efficiency at maximum power is roughly size-independent, the power itself slightly increases with the dimension, quickly saturating to a constant. Thus, interestingly, scaling up autonomous quantum heat pumps does not render a significant enhancement beyond the optimal double-stage configuration.

description: We study the phase diagram of the anisotropic spin-1 Heisenberg chain with single ion anisotropy (D) using a ground-state fidelity approach. The ground-state fidelity and its corresponding susceptibility are calculated within the quantum renormalization group scheme where we obtained the renormalization of fidelity preventing to calculate the ground state. Using this approach, the phase boundaries between the antiferromagnetic Néel, Haldane and large-D phases are obtained for the whole phase diagram, which justifies the application of quantum renormalization group to trace the symmetery protected topological phases. In addition, we present numerical exact diagonalization (Lanczos) results in, which we employ a recently introduced non-local order parameter to locate the transition from Haldane to large-D phase accurately.

description: For the first time, with the Laue project, bent crystals are being used for focusing photons in the 80-300 keV energy range. The advantage is their high reflectivity and better Point Spread Function with respect to the mosaic flat crystals. Simulations have already shown their excellent focusing capability which makes them the best candidates for a Laue lens whose sensitivity is also driven by the size of the focused spot. Selected crystals are Germanium (perfect, (111)) and Gallium Arsenide (mosaic, (220)) with 40 m curvature radius to get a spherical lens with 20 m long focal length. A lens petal is being built. We report the measurement technique by which we are able to estimate the exact curvature of each tile within a few percent of uncertainty and their diffraction efficiency. We also discuss some results.

description: Adhoc wireless network with their changing topology and distributed nature are more prone to intruders. The efficiency of an Intrusion detection system in the case of an adhoc network is not only determined by its dynamicity in monitoring but also in its flexibility in utilizing the available power in each of its nodes. In this paper we propose a hybrid intrusion detection system, based on a power level metric for potential adhoc hosts, which is used to determine the duration for which a particular node can support a network-monitoring node. The detection of intrusions in the network is done with the help of Cellular Automata (CA). IDFADNWCA (Intrusion Detection for Adhoc Networks with Cellular Automata) focuses on the available power level in each of the nodes and determines the network monitors. Power Level Metric in the network results in maintaining power for network monitoring, with monitors changing often, since it is an iterative power optimal solution to identify nodes for distributed agent based intrusion detection. The advantage of this approach entails is the inherent flexibility it provides, by means of considering only fewer nodes for reestablishing network monitors.

description: In den 25 Jahren von 1993 bis 2018 – über die Jahrtausendwende hinweg – haben sich die Methodik und das Instrumentarium der Geodäsie revolutionär weiterentwickelt. Dies betrifft sowohl neue Entwicklungen in der Satellitengeodäsie, vorangetrieben durch den Aufbau verschiedener globaler Satellitennavigationssysteme, insbesondere GPS, aber auch spezifische geodätische Satellitenmissionen wie GRACE, GOCE, TerraSAR-X und TanDEMX als auch methodische Neuerungen in der Industrievermessung (Large Volume Metrology / Sensorik). Durch die ständig wachsende Menge an zu verarbeitenden Daten kommt zudem dem effizienten Management und der Verarbeitung großer Mengen georeferenzierter Daten eine besondere Bedeutung zu. Gleichbedeutend, wenn nicht gar in den letzten Jahren noch gestiegen ist die Notwendigkeit zur interdisziplinären Ausrichtung der Geodäsie. Die Geodäsie kann sich heute als Drehscheibe zwischen verschiedensten Disziplinen wie beispielsweise dem Bauingenieurwesen und den Geowissenschaften, aber auch dem Maschinenbau oder der
Luft- und Raumfahrttechnik bezeichnen.
Auf die neuen Herausforderungen hat das Geodätische Institut auf vielfältige Weise reagiert: Zum Wintersemester 2010/11 wurde der Lehrstuhl für Mathematische und Datenverarbeitende Geodäsie umgewidmet in den Lehrstuhl für Geoinformatik (siehe auch Abschnitt "Strukturelle und personelle Veränderungen"), auf den Prof. Martin Breunig berufen wurde. Der Lehrstuhl
versteht sich seither als bindendes Glied zwischen der Geodäsie, den Bauingenieur- und den Geowissenschaften. Die interdisziplinäre Arbeitsweise spiegelt sich auch in der DFGForschergruppe 3D Tracks wider, von der später in dieser Festschrift noch die Rede sein wird. Die jüngsten Veränderungen betreffen den Lehrstuhl "Physikalische und Satellitengeodäsie", der zum Wintersemester 2018/19 im Zuge der Wiederbesetzung durch Prof. Hansjörg Kutterer in "Geodätische Erdsystemwissenschaft" umgewidmet wurde, verbunden mit einer Neuausrichtung des Lehr- und Forschungsgebiets sowie einer noch stärkeren Fokussierung
auf geowissenschaftliche Themen.
Als der Lehrstuhl Geodäsie I im Jahre 2000 neu besetzt wurde, wurde mit der Umwidmung in "Vermessungskunde und Geodätische Sensorik" mit dem expliziten Verweis auf Sensorik bewusst die Tür in die dimensionelle Messtechnik geöffnet, wobei gleichfalls die Basisausbildung in Vermessungskunde auch für Nachbardisziplinen garantiert werden sollte. Heute
versteht sich der Lehrstuhl als Teildisziplin der Metrologie, also der Wissenschaft des Messens (vgl. auch den Abschnitt "Das Mess- und Kalibrierlabor des Geodätischen Instituts im Kontext aktueller Herausforderungen" in diesem Band) und stellt die geodätischen Messtechniken in einem eher grundsätzlichen Kontext dar. Dies ermöglicht barrierefreie Interaktion mit anderen
Ingenieurdisziplinen, vor allen Dingen der Large Volume Metrology (LVM) im Maschinenbau. In diesem Zusammenhang werden auch Entwicklungen von Messmitteln vorangetrieben.

Such structures will permit detailed studies of the impact of alloy disorder in the fractional quantum Hall regime. At zero magnetic field, we extract an alloy scattering rate of 24 ns-1 per %Al. Additionally we find that for x as low as 0.00057 in the quantum well, alloy scattering becomes the dominant mobility-limiting scattering mechanism in ultra-high purity two-dimensional electron gases typically used to study the fragile nu=5/2 and nu=12/5 fractional quantum Hall states.

description: There is a growing interest in differentiation algorithms that converge in fixed time with a predefined Upper Bound on the Settling Time (UBST). However, existing differentiation algorithms are limited to signals having an $n$-th order Lipschitz derivative. Here, we introduce a general methodology based on time-varying gains to circumvent this limitation, allowing us to design $n$-th order differentiators with a predefined UBST for the broader class of signals whose $(n+1)$-th derivative is bounded by a function with bounded logarithmic derivative. Unlike existing methods whose time-varying gain tends to infinity, our approach yields a time-varying gain that remains bounded at convergence time. We show how this last property maintains exact convergence using bounded gains when considering a compact set of initial conditions and improves the algorithm's performance to measurement noise.

Postcolonial Discourse and Ousmane Sembene's Cinema
Creators: name: Namaz, Yunus

Year: 2023
Subjects: Postcolonialism, Postcolonial Discourse, African Cinema, Ousmane Sembene, Multimodal Film Analysis.

description: This study focuses on the relationship between African cinema and colonialism and postcolonial discourse addresses the cinema of Senegalese director Ousmane Sembene in Sub-Saharan Africa. In Sembene’s films, it was first determined which postcolonial discourses were handled and these discourses were examined by multimodal film analysis. In this study, in which four of the feature films from 1960-2004 were analyzed, the focus was on how postcolonial discourse contributed to the content of the film and which layers corresponded to morphological features and film technique in multi-layered film analysis. Directed by La Noire de ... (1966), Xala (1975), Camp de Thiaroye (1988) and Moolaade (2004) are examples of this work. The film experience of Sembene for over forty years emphasises how the postcolonial discourse has changed in the historical process, the results of pre-colonial and post-colonial themes varying. When the films of Sembene are analyzed, three movies (La Noire de..., Xala, Moolaade) have reached the point where the problems in postcolonial Africa are placed mainly, and in the case of a film (Camp de Thiaroye), attention is drawn to the historicity of the colonial period. It also concludes that in these films the seven postcolonial layers are not evenly processed in each film and that filming varies according to the thematic structure it deals with. It has been observed that in neo-colonialism, postcolonialism colonizer and colonized the relation of multimodal film analysis to the “background, explanation, contrast and parallel” layers is directly related. La Noire and Camp de Thiaroye have a complex narrative structure and a variety of film techniques that have contributed significantly to the discovery of different layers in terms of multimodal analysis.

description: In accreting neutron star binaries, matter is channelled by the magnetic fields from the accretion disc to the poles of neutron stars forming an accretion mound. We model such mounds by numerically solving the Grad-Shafranov equation for axisymmetric static MHD equilibria. From our solutions we infer local distortion of field lines due to the weight of accreted matter. Variation in mass loading at the accretion disc will alter the shape of the accretion mound which will also affect the local field distortion. From simulations of cyclotron resonance scattering features from HMXBs, we conclude that local field distortion will greatly affect the shape and nature of the CRSF. From phase resolved spectral analysis one can infer the local field structure and hence the nature of mass loading of field lines at the accretion disc. We also study the stability of such mounds by performing MHD simulations using the PLUTO MHD code. We find that pressure and gravity driven instabilities depend on the total mass accreted and the nature of mass loading of the field lines.

description: Let $D\geq 1$ and $q\geq 3$ be two integers. Let $H(D)=H(D,q)$ denote the $D$-dimensional Hamming graph over a $q$-element set. Let ${\mathcal T}(D)$ denote the Terwilliger algebra of $H(D)$. Let $V(D)$ denote the standard ${\mathcal T}(D)$-module. Let $ω$ denote a complex scalar. We consider a unital associative algebra $\mathfrak K_ω$ defined by generators and relations. The generators are $A$ and $B$. The relations are $A^2 B-2 ABA +B A^2 =B+ωA$, $B^2A-2 BAB+AB^2=A+ωB$. The algebra $\mathfrak K_ω$ is the case of the Askey-Wilson algebras corresponding to the Krawtchouk polynomials. The algebra $\mathfrak K_ω$ is isomorphic to ${\rm U}(\mathfrak{sl}_2)$ when $ω^2\not=1$. We view $V(D)$ as a $\mathfrak{K}_{1-\frac{2}{q}}$-module. We apply the Clebsch-Gordan rule for ${\rm U}(\mathfrak{sl}_2)$ to decompose $V(D)$ into a direct sum of irreducible ${\mathcal T}(D)$-modules.

description: Recently a broad class of superconformal inflationary models was found leading to a universal observational prediction $n_s=1-2/N$ and $r=12/N^2$. Here we generalize this class of models by introducing a parameter $α$ inversely proportional to the curvature of the inflaton Kahler manifold. In the small curvature (large $α$) limit, the observational predictions of this class of models coincide with the predictions of generic chaotic inflation models. However, for sufficiently large curvature (small $α$), the predictions converge to the universal attractor regime with $n_s=1-2/N$ and $r=12α/N^2$, which corresponds to the part of the $n_s-r$ plane favored by the Planck data.

description: We consider a mathematical model of synthetic aperture radar (SAR) with a known, possibly non-flat, topography. In this context we consider the problem of recovering the wavefront set of the ground reflectivity, given radar data measured along a curved flight path. We show that if singularities are located at "mirror points," then the resulting data may be smooth; in effect, the singularities "cancel." With a flat topography, these mirror points are always discrete, but we show that in a non-flat topography there may be infinite families of mirror points.

description: We use an automated galaxy morphology analysis method to quantitatively measure the spirality of galaxies classified manually as elliptical. The data set used for the analysis consists of 60,518 galaxy images with redshift obtained by the Sloan Digital Sky Survey (SDSS) and classified manually by Galaxy Zoo, as well as the RC3 and NA10 catalogues. We measure the spirality of the galaxies by using the Ganalyzer method, which transforms the galaxy image to its radial intensity plot to detect galaxy spirality that is in many cases difficult to notice by manual observation of the raw galaxy image. Experimental results using manually classified elliptical and S0 galaxies with redshift <0.3 suggest that galaxies classified manually as elliptical and S0 exhibit a nonzero signal for the spirality. These results suggest that the human eye observing the raw galaxy image might not always be the most effective way of detecting spirality and curves in the arms of galaxies.

description: Class I protostars in three high-mass star-forming regions are found to have correlations among the local projected density of other Class I protostars, the summed flux from these other protostars, and the protostellar luminosity in the WISE 22 micron band. Brighter Class I sources form in higher-density and higher-flux regions, while low luminosity sources form anywhere. These correlations depend slightly on the number of neighbors considered (from 2 to 20) and could include a size-of-sample effect from the initial mass function (i.e., larger numbers include rarer and more massive stars). Luminosities seem to vary by neighborhood with nearby protostars having values proportional to each other and higher density regions having higher values. If Class I luminosity is partially related to the accretion rate, then this luminosity correlation is consistent with the competitive accretion model, although it is more collaborative than competitive. The correlation is also consistent with primordial mass segregation, and could explain why the stellar initial mass function resembles the dense core mass function even when cores form multiple stars.

description: Three-dimensional (3D) topological Dirac semimetals (TDSs) represent a novel state of quantum matter that can be viewed as '3D graphene'. In contrast to two-dimensional (2D) Dirac fermions in graphene or on the surface of 3D topological insulators, TDSs possess 3D Dirac fermions in the bulk. The TDS is also an important boundary state mediating numerous novel quantum states, such as topological insulators, Weyl semi-metals, Axion insulators and topological superconductors. By investigating the electronic structure of Na3Bi with angle resolved photoemission spectroscopy, we discovered 3D Dirac fermions with linear dispersions along all momentum directions for the first time. Furthermore, we demonstrated that the 3D Dirac fermions in Na3Bi were protected by the bulk crystal symmetry. Our results establish that Na3Bi is the first model system of 3D TDSs, which can also serve as an ideal platform for the systematic study of quantum phase transitions between rich novel topological quantum states.

description: Im Rahmen der Arbeit „So gelingt demokratische Partizipation“ befassen sich Simone Allenspach und Gian Luca Casanova mit der Frage, welche Rahmenbedingungen und Methoden für eine gelingende demokratische Partizipation – spezifisch von Kindern und Jugendlichen – in der Schweiz förderlich sind. Dazu wird zuerst der Begriff der demokratischen Partizipation anhand von wissenschaftlicher Literatur definiert und mit Inhalt gefüllt. Daraus werden Ziele der demokratischen Partizipation abgeleitet, die dann den aktuellen Forschungsergebnissen zur demokratischen Partizipation in der Schweiz gegenübergestellt werden. Um einen Auftrag der Soziokulturellen Animation im Wirkungsfeld der demokratischen Partizipation formulieren zu können, muss der Sozialisierungsprozess beleuchtet und müssen Gemeinsamkeiten und Differenzen mit anderen Sozialisationsinstanzen aufgezeigt werden. Es wird die Rolle der professionellen Soziokulturellen Animation definiert und untersucht, wie das professionelle Handeln gegenüber Dritten legitimiert werden kann. Um auf die Frage antworten zu können, wie eine gelingende demokratische Partizipation sichergestellt werden und welchen Teil die Soziokulturelle Animation dazu beitragen kann, werden zuerst die Rahmenbedingungen definiert, die förderlichen und hinderlichen Aspekte festgehalten, um danach die Chancen und Risiken aufzeigen zu können, auf welche die Soziokulturelle Animation in diesem Handlungsfeld stossen kann. Anschliessend wird untersucht, welche Bedingungen erfüllt sein müssen, um eine möglichst effiziente und effektive Zusammenarbeit aufbauen und erhalten zu können. Dazu werden unterschiedliche Handlungsprinzipien aufgezeigt. Wenn die Soziokulturelle Animation Methoden zur Verfügung stellt, um Interessen, Bedürfnisse und Erfahrungen sichtbar zu machen, stärkt sie die demokratische Partizipation von Kindern und Jugendlichen einerseits und –in ihrer zirkulären Wirkung - von allen anderen Beteiligten andererseits.

Diffusion of gravity waves by random space inhomogeneities in pancake-ice fields. Theory and validation with wave buoys and synthetic aperture radar

description: We study the diffusion of ocean waves by ice bodies much smaller than a wavelength, such as pancakes and small ice floes. We argue that inhomogeneities in the ice cover at scales comparable to that of the wavelength significantly increase diffusion, producing a contribution to wave attenuation comparable to what is observed in the field and usually explained by viscous effects. The resulting attenuation spectrum is characterized by a peak at the scale of the inhomogeneities in the ice cover, which could explain the rollover of the attenuation profile at small wavelengths observed in field experiments. The proposed attenuation mechanism leads to the same behaviors that would be produced by a viscous wave model with effective viscosity linearly dependent on the ice thickness. This may explain recent findings that viscous wave models require a thickness-dependent viscosity to fit experimental attenuation data. Experimental validation is carried out using wave buoy attenuation data and synthetic aperture radar image analysis.

Detection of high-degree prograde sectoral mode sequences in the A-star KIC 8054146?

description: This paper examines the 46 frequencies found in the Delta Sct star KIC 8054146 involving a frequency spacing of exactly 2.814 c/d (32.57 microHz), which is also a dominant low-frequency peak near or equal to the rotational frequency. These 46 frequencies range up to 146 c/d. Three years of Kepler data reveal distinct sequences of these equidistantly spaced frequencies, including the basic sequence and side lobes associated with other dominant modes (i.e., small amplitude modulations). The amplitudes of the basic sequence show a high-low pattern. The basic sequence follows the equation fm = 2.8519 + m * 2.81421 c/d with m ranging from 25 to 35. The zero-point offset and the lack of low-order harmonics eliminate an interpretation in terms of a Fourier series of a non-sinusoidal light curve. The exactness of the spacing eliminates high-order asymptotic pulsation. The frequency pattern is not compatible with simple hypotheses involving single or multiple spots, even with differential rotation. The basic high-frequency sequence is interpreted in terms of prograde sectoral modes. These can be marginally unstable, while their corresponding low-degree counterparts are stable due to stronger damping. The measured projected rotation velocity (300 km/s) indicates that the star rotates with app. 70% of the Keplerian break-up velocity. This suggests a near equator-on view. We qualitatively examine the visibility of prograde sectoral high-degree g-modes in integrated photometric light in such a geometrical configuration and find that prograde sectoral modes can reproduce the frequencies and the odd-even amplitude pattern of the high-frequency sequence.

description: The radial basis function (RBF) approach is applied in predicting nuclear masses for 8 widely used nuclear mass models, ranging from macroscopic-microscopic to microscopic types. A significantly improved accuracy in computing nuclear masses is obtained, and the corresponding rms deviations with respect to the known masses is reduced by up to 78%. Moreover, strong correlations are found between a target nucleus and the reference nuclei within about three unit in distance, which play critical roles in improving nuclear mass predictions. Based on the latest Weizsäcker-Skyrme mass model, the RBF approach can achieve an accuracy comparable with the extrapolation method used in atomic mass evaluation. In addition, the necessity of new high-precision experimental data to improve the mass predictions with the RBF approach is emphasized as well.

KPZ equation with a small noise, deep upper tail and limit shape

description: In this paper, we consider the KPZ equation under the weak noise scaling. That is, we introduce a small parameter $\sqrt{\varepsilon}$ in front of the noise and let $\varepsilon \to 0$. We prove that the one-point large deviation rate function has a $\frac{3}{2}$ power law in the deep upper tail. Furthermore, by forcing the value of the KPZ equation at a point to be very large, we prove a limit shape of the KPZ equation as $\varepsilon \to 0$. This confirms the physics prediction in Kolokolov and Korshunov (2007), Kolokolov and Korshunov (2009), Meerson, Katzav, and Vilenkin (2016), Kamenev, Meerson, and Sasorov (2016), and Le Doussal, Majumdar, Rosso, and Schehr (2016).
