description: In this paper, the thesis is put forward that selective outcome incentives for party membership gain relevance over time. Two possible mechanisms are identified as the cause of this increase in importance: a supply-side mechanism based on processes of societal change that took place through generational succession and a demand-side mechanism focusing on shifts in the self-image and organizational structure of political parties. The supply-side mechanism should lead to changes in the motives of potential members, whereas the demand-side mechanism alters the incentives potential and current members are exposed to. The empirical analyses are based on the German Party Membership Studies of 1998, 2009 and 2017. These three studies are nationwide representative surveys of the members of the following six parties: Christian Democratic Union (CDU), Christian Social Union (CSU), Social Democratic Party of Germany (SPD), Free Democratic Party (FDP), Alliance90/The Greens (Bündnis90/Die Grünen), and The Left (Die Linke). Within the German Party Membership Studies, both the motives for joining the party and the current membership motives are surveyed. Empirically, it is shown that there is indeed an increase in the importance of selective outcome membership motives over the period under study. The mechanisms behind this increase in importance are investigated using multivariate Age-Period-Cohort (APC) models based on the cumulated data of the German Party Membership Studies. These analyses are based on a total of nearly 30,000 cases. The results of the APC analyses are largely consistent with the supply-side explanation of the increased importance of selective outcome motives for party entry and membership. The demand-side explanation is only partially confirmed.

description: The search of a clustering signal in the arrival directions of ultra-high-energy cosmic rays (UHECRs) is a standard method to assess the level of anisotropy of the data sets under investigation. Here, we first show how to quantify the sensitivity of a UHECR detector to the detection of anisotropy, and then propose a new method that pushes forward the study of the two-point auto-correlation function, enabling one to put astrophysically meaningful constraints on both the effective UHECR source density and the angular deflections that these charged particles suffer while they propagate through the galactic and intergalactic magnetic fields. We apply the method to simulated data sets obtained under various astrophysical conditions, and show how the input model parameters can be estimated through our analysis, introducing the notion of "clustering similarity" (between data sets), to which we give a precise statistical meaning. We also study how the constraining power of the method is influenced by the size of the data set under investigation, the minimum energy of the UHECRs to which it is applied, and a prior assumption about the underlying source distribution. We also show that this method is particularly adapted to data sets consisting of a few tens to a few hundreds of events, which corresponds to the current and near-future observational situation in the field of UHECRs.

description: Recovering credible cosmological parameter constraints in a weak lensing shear analysis requires an accurate model that can be used to marginalize over nuisance parameters describing potential sources of systematic uncertainty, such as the uncertainties on the sample redshift distribution $n(z)$. Due to the challenge of running Markov Chain Monte-Carlo (MCMC) in the high dimensional parameter spaces in which the $n(z)$ uncertainties may be parameterized, it is common practice to simplify the $n(z)$ parameterization or combine MCMC chains that each have a fixed $n(z)$ resampled from the $n(z)$ uncertainties. In this work, we propose a statistically-principled Bayesian resampling approach for marginalizing over the $n(z)$ uncertainty using multiple MCMC chains. We self-consistently compare the new method to existing ones from the literature in the context of a forecasted cosmic shear analysis for the HSC three-year shape catalog, and find that these methods recover similar cosmological parameter constraints, implying that using the most computationally efficient of the approaches is appropriate. However, we find that for datasets with the constraining power of the full HSC survey dataset (and, by implication, those upcoming surveys with even tighter constraints), the choice of method for marginalizing over $n(z)$ uncertainty among the several methods from the literature may significantly impact the statistical uncertainties on cosmological parameters, and a careful model selection is needed to ensure credible parameter intervals.

description: Carrier-selective and passivating SiOx/TiOy heterocontacts are an attractive alternative to conventional contacts due to their high efficiency potentials combined with relatively simple processing schemes. It is widely accepted that post deposition annealing is necessary to obtain high photovoltaic efficiencies, especially for full area aluminum metallized contacts. Despite some previous high-level electron microscopy studies, the picture of atomic-scale processes underlying this improvement seems to be incomplete. In this work, we apply nanoscale electron microscopy techniques to macroscopically well-characterized solar cells with SiOx/TiOy/Al rear contacts on n-type silicon. Macroscopically, annealed solar cells show a tremendous decrease of series resistance and improved interface passivation. Analyzing the microscopic composition and electronic structure of the contacts, we find that partial intermixing of the SiOx and TiOy layers occurs due to annealing, leading to an apparent thickness reduction of the passivating SiOx. However, the electronic structure of the layers remains clearly distinct. Hence, we conclude that the key to obtain highly efficient SiOx/TiOy/Al contacts is to tailor the processing such that the excellent chemical interface passivation of a SiOx layer is achieved for a layer thin enough to allow efficient tunneling through the layer. Furthermore, we discuss the impact of aluminum metallization on the above mentioned processes.

description: We have studied the laser induced ultrafast quenching of Gd 4f magnetic order in ferrimagnetic Co100-xGdx alloys to highlight the role of the inter-atomic exchange coupling. We have taken advantage of the ultrashort soft X-ray pulses deliver by the femtoslicing beamline at the BESSY II synchrotron radiation source at the Helmholtz-Zentrum Berlin to perform element- and time-resolved X-ray Magnetic Circular Dichroism spectroscopy.Our results show that the laser induced quenching of Gd 4f magnetic order occurs on very different time-scales for the Co72Gd28, the Co77Gd23 and the Co79Gd21 alloys. Most of the magnetic moment losses occur within the first picosecond (ps) while the electron distribution is strongly out of equilibrium. After the equilibration of the electrons and lattice temperatures (t > 1 ps), the magnetic losses occur on slower rates that depend on the alloy composition: increasing the Co composition speeds up the demagnetization of Gd 4f sublattice. The strength of the inter-atomic exchange coupling which depends on composition, determines the efficiency of the angular momentum flow from the Gd 4f spin towards the lattice. Our results are in qualitative agreements with the predictions of the microscopic three temperatures model for ferrimagnetic alloys.

Multi-phase view of the ISM in the Carina Nebula

description: The Carina Nebula Complex (CNC) is a spectacular star-forming region located at a distance of 2.3 kpc, which is close enough to observe a wide range of size scales in detail. With more than 65 O-stars and more than 900 young stellar objects identified it is also the nearest analogue of more extreme star forming regions, such as 30 Doradus.  In this talk I will present the results of a major effort to study the relationship between the different gas phases in the Carina region from 100 pc to 0.01 pc using the Australia Telescope Compact Array, the Mopra telescope and ALMA.  At large scales, CO image combined with far-infrared data from Herschel revealed the overall molecular mass and its distribution across the CNC.  An extremely detailed map of the HI 21-cm line across the whole nebula revealed a complex filamentary structure in the atomic gas, which allowed the identification of regions where phase transition between atomic and molecular gas is happening. Most recently, we have released a 1-3 GHz radio continuum image across the whole Caria region, revealing a complete and spectacular view of the ionized gas in the region.  At small scales, ALMA high spatial resolution observations of molecular line tracers and dust showed that the level of stellar feedback effectively influences the fragmentation process in clumps, and provides further evidence for a higher level of turbulence in the material with a higher level of massive stellar feedback.

description: This paper investigates the polytropic matter shell collapse in the non-commutative Reissner-Nordstr$\ddot{o}$m geometry. Using the Israel criteria, equation of motion for the polytropic matter shell is derived. In order to explore the physical aspects of this equation, the most general equation of state, $p=kρ^{({1+\frac{1}{n}})}$, has been used for finite and infinite values of $n$. The effective potentials corresponding to the equation of motion have been used to explain different states of the matter shell collapse. The numerical solution of the equation of motion predicts collapse as well as expansion depending on the choice of initial data. Further, in order to include the non-commutative correction, we modify the matter components and re-formulate the equation of motion as well as the corresponding effective potentials by including non-commutative factor and charge parameter. It is concluded that charge reduces the velocity of the expanding or collapsing matter shell but does not bring the shell to static position. While the non-commutative factor with generic matter favors the formation of black hole.

description: We present the AGILE gamma-ray observations in the energy range 50 MeV - 10 GeV of the supernova remnant (SNR) W44, one of the most interesting systems for studying cosmic-ray production. W44 is an intermediate-age SNR (20, 000 years) and its ejecta expand in a dense medium as shown by a prominent radio shell, nearby molecular clouds, and bright [SII] emitting regions. We extend our gamma-ray analysis to energies substantially lower than previous measurements which could not conclusively establish the nature of the radiation. We find that gamma-ray emission matches remarkably well both the position and shape of the inner SNR shocked plasma. Furthermore, the gamma-ray spectrum shows a prominent peak near 1 GeV with a clear decrement at energies below a few hundreds of MeV as expected from neutral pion decay. Here we demonstrate that: (1) hadron-dominated models are consistent with all W44 multiwavelength constraints derived from radio, optical, X-ray, and gamma-ray observations; (2) ad hoc lepton-dominated models fail to explain simultaneously the well-constrained gamma-ray and radio spectra, and require a circumstellar density much larger than the value derived from observations; (3) the hadron energy spectrum is well described by a power-law (with index s = 3.0 \pm 0.1) and a low-energy cut-off at Ec = 6 \pm 1 GeV. Direct evidence for pion emission is then established in an SNR for the first time.

Sensor Observability Index: Evaluating Sensor Alignment for Task-Space Observability in Robotic Manipulators

Publisher: name: arXiv
Year: 2022
Subjects: subject: Robotics (cs.RO)

description: In this paper, we propose a preliminary definition and analysis of the novel concept of sensor observability index. The goal is to analyse and evaluate the performance of distributed directional or axial-based sensors to observe specific axes in task space as a function of joint configuration in serial robot manipulators. For example, joint torque sensors are often used in serial robot manipulators and assumed to be perfectly capable of estimating end effector forces, but certain joint configurations may cause one or more task-space axes to be unobservable as a result of how the joint torque sensors are aligned. The proposed sensor observability provides a method to analyse the quality of the current robot configuration to observe the task space. Parallels are drawn between sensor observability and the traditional kinematic Jacobian for the particular case of joint torque sensors in serial robot manipulators. Although similar information can be retrieved from kinematic analysis of the Jacobian transpose in serial manipulators, sensor observability is shown to be more generalizable in terms of analysing non-joint-mounted sensors and other sensor types. In addition, null-space analysis of the Jacobian transpose is susceptible to false observability singularities. Simulations and experiments using the robot Baxter demonstrate the importance of maintaining proper sensor observability in physical interactions.

Thermoelectric response across the semiconductor-semimetal transition in black phosphorus

description: In spite of intensive studies on thermoelectricity in metals, little is known about thermoelectric response in semiconductors at low temperature. An even more fascinating and unanswered question is what happens to the Seebeck coefficient when the semiconductor turns to a metal. By precisely tuning the ground state of black phosphorus with pressure from the semiconducting to semimetallic state, we track a systematic evolution of the Seebeck coefficient. Thanks to a manifest correlation between the Seebeck coefficient and resistivity, the Seebeck response in each conduction regime, i.e., intrinsic, saturation, extrinsic, and variable range hopping (VRH) regimes, is identified. In the former two regimes, the Seebeck coefficient behaves in accordance with the present theories, whereas in the later two regimes available theories do not give a satisfactory account for its response. However, by eliminating the extrinsic sample dependence in the resistivity $ρ$ and Seebeck coefficient $S$, the Peltier conductivity $α=S/ρ$ allows to unveil the intrinsic thermoelectric response, revealing vanishing fate for $α$ in the VRH regime. The emerged ionized impurity scattering on entry to the semimetallic state is easily surpassed by electron-electron scattering due to squeezing of screening length accompanied by an increase of carrier density with pressure. In the low temperature limit, a small number of carriers enhances a prefactor of $T$-linear Seebeck coefficient as large as what is observed in prototypical semimetals. A crucial but largely ignored role of carrier scattering in determining the magnitude and sign of the Seebeck coefficient is indicated by the observation that a sign reversal of the $T$-linear prefactor is concomitant with a change in dominant scattering mechanism for carriers.

description: All large superconducting applications require electrical connections between superconductors or between superconductors and other metallic parts of the systems. Such connections are essential components for these applications and are usually made by melting the solder (or soft soldering). In general, the melting point, electrical resistivity, mechanical and wetting properties and toxicity are all important criteria when choosing the best solder for a specific application. If the solder itself is superconducting under the operating conditions of the application then there is also the possibility of extremely low resistance joints. In this work we report on the superconducting properties of six low melting point solders: Bi49Pb18In21Sn12 (Cerrolow 136), Pb20Sn34Bi46, Pb20Sn60Bi20, In52Sn48, Pb38Sn62 and Pb57Bi36Sb7 and the mechanical properties of three of the six solders (Pb38Sn62, Cerrolow 136 and Pb20Sn34Bi46). We have found that all the solders except Pb38Sn62 and In52Sn48 have relatively high upper critical fields (higher than 2 T) at temperatures lower than 3 K. Although the good ductility and high maximum fracture elongation of Pb38Sn62 is useful when using low temperature superconductors, other solders may be preferred with high temperature superconductors because their lower melting temperatures mean they are less likely to delaminate them.

description: We produce oriented rotational wave packets in CO and measure their characteristics via high harmonic generation. The wavepacket is created using an intense, femtosecond laser pulse and its second harmonic. A delayed 800 nm pulse probes the wave packet, generating even-order high harmonics that arise from the broken symmetry induced by the orientation dynamics. The even-order harmonic radiation that we measure appears on a zero background, enabling us to accurately follow the temporal evolution of the wave packet. Our measurements reveal that, for the conditions optimum for harmonic generation, the orientation is produced by preferential ionization which depletes the sample of molecules of one orientation.

description: By using dynamical invariants theory, Hassoul et al. [1,2] investigate the quantum dynamics of two (2D) and three (3D) dimensional time-dependent coupled oscillators. They claim that, in the 2D case, introducing two pairs of annihilation and creation operators uncouples the original invariant operator so that it becomes the one that describes two independent subsystems. For the 3D case, the authors pretend that they have obtained a diagonalized invariant which is exactly the sum of three simple harmonic oscillators. We show that their investigations suffer from basic errors and therefore the found results are not valid .

description: The RhoGEF Trio is a large multi-domain protein and an activator of the small GTPases Rac1, RhoG, and RhoA. Although Trio has been implicated in many cellular mechanisms like leukocyte transendothelial migration, cell-cell junction stability, lamellipodia formation, axon outgrowth, and muscle fusion, it remains unclear how Trio is activated. Using stable isotope labelling by amino acids in cell culture (SILAC)-based mass spectrometry analysis of endothelial cells, we identified two serine residues (S1785/S1786) located in between the two exchange domains of Trio that were highly phosphorylated upon short thrombin treatment. Using phosphomimetic Trio S1785D/S1786D double mutants, we did not find an increase in Rac1/RhoG activity, indicating that the phosphorylation events do not increase Trio exchange activity. However, we found that the Trio mutants localized more strongly at cell-cell junctions and prevented junction destabilization upon thrombin treatment, judged by junction linearity. Our data suggest that serine phosphorylation of Trio potentiates the localization of Trio to junctional regions, resulting in locally promoting the exchange for Rac1 at junction regions and increasing endothelial cell-cell junction stability upon permeability-inducing reagents such as thrombin.
Fabrication and characterization of nanoparticulate and related iridium oxide-based glucose biosensors

description: The electrochemical oxidation of glucose utilizing nanoparticulate hydrous Ir oxide (IrOx) films, formed using an approach similar to sol-gel (SG) synthesis, was studied in neutral phosphate buffer solution. The results were compared to glucose detection at IrOx films formed electrochemically on bulk Ir wires and foils. The synthesis of the Ir sol involved an Ir precursor (IrCy and a reducing agent (sodium ethoxide) refluxed in ethanol. The sol was found to be composed of stable metallic nanoparticles of Ir (~ 2 nm in dia.) suspended in the solution phase. Several techniques were used to characterize the products and films formed from the Ir sol. Cyclic Voltammetry (CV) results showed that approximately 46% of the IrCl3 was converted to metallic Ir in the sol phase, while the remaining 54% was present in the precipitate phase. The precipitate phase was composed mainly of Ir02, based on the X-Ray Diffraction, CV and Thermogravimetric analysis results, in both pure ethanol and in a 50:50 ethanohwater solvent, employed to stabilize the enzyme, glucose oxidase (GOx). GOx was immobilized in the IrOx films formed by the electrochemical oxidation of the Ir sol in neutral buffer solutions, and the response of these films to glucose was studied under a range of conditions. It was found that these films respond well to glucose in the presence of oxygen, utilizing the oxidation/reduction signal of H2O2 (non-mediated conditions). As well, these films also showed a very good response to glucose in the absence of oxygen by regenerating the GOx active sites via the Ir(III)/Ir(IV) oxide redox sites. When coated with Nafion®, these films showed a very good selectivity towards glucose, and were unresponsive to interferences like ascorbic acid, uric acid and acetaminophen. The characterization of the Ir-GOx sol-derived films using Transmission Electron Microscopy showed that the Ir/IrOx particles retained their nanometer size (2.2 nm in dia). However, the CV results demonstrated that the IrOx electrochemistry was suppressed at high GOx concentrations in the film. The Michaelis-Menten kinetics (MM) plots for these films were examined, and the kinetic parameters, such as the apparent MM constant (K'm ) and the maximum reaction velocity (imax) were also determined. It was shown that K'm values for the mediated conditions are higher than for the non-mediated, at the same GOx concentrations. Also, a deeper analysis of these kinetic parameters shows that glucose detection at sol-based IrOx films is more sensitive, reproducible and stable vs. glucose biosensors fabricated using bulk Ir.

description: In this paper, we give a characterization of digraphs $Q, |Q|\leq 4$ such that the associated Hecke-Kiselman monoid $H_Q$ is finite. In general, a necessary condition for $H_Q$ to be a finite monoid is that $Q$ is acyclic and its Coxeter components are Dynkin diagram. We show, by constructing examples, that such conditions are not sufficient.

A data-driven approach to viscous fluid mechanics -- the stationary case

description: We introduce a data-driven approach to the modelling and analysis of viscous fluid mechanics. Instead of including constitutive laws for the fluid's viscosity in the mathematical model, we suggest to directly use experimental data. Only a set of differential constraints, derived from first principles, and boundary conditions are kept of the classical PDE model and are combined with a data set. The mathematical framework builds on the recently introduced data-driven approach to solid-mechanics [KO16,CMO18]. We construct optimal data-driven solutions that are material model free in the sense that no assumptions on the rheological behaviour of the fluid are made or extrapolated from the data. The differential constraints of fluid mechanics are recast in the language of constant rank differential operators. Adapting abstract results on lower-semicontinuity and $\mathscr{A}$-quasiconvexity, we show a $Γ$-convergence result for the functionals arising in the data-driven fluid mechanical problem. The theory is extended to compact nonlinear perturbations, whence our results apply to both inertialess fluids and flows with finite Reynolds number. Data-driven solutions provide a new relaxed solution concept. We prove that the constructed data-driven solutions are consistent with solutions to the classical PDEs of fluid mechanics if the data sets have the form of a monotone constitutive relation.

description: It is now known (or in some cases just believed) that many quantum field theories exhibit dualities, equivalences with the same or a different theory in which things appear very different, but the overall physical implications are the same. We will discuss some of these dualities from the point of view of a mathematician, focusing on "charge conservation" and the role played by K-theory and noncommutative geometry. Some of the work described here is joint with Mathai Varghese and Stefan Mendez-Diez; the last section is new.

Signature of exceptional point phase transition in Hermitian systems

description: Exceptional point (EP) is a spectral singularity in non-Hermitian systems. The passing over the EP leads to a phase transition, which endows the system with unconventional features that find a wide range of applications. However, the need of using the dissipation and amplification limits the possible applications of systems with the EP. In this work, we demonstrate an existence of signature of exceptional point phase transition in Hermitian systems that are free from dissipation and amplification. We consider a composite Hermitian system including both two coupled oscillators and their environment consisting only of several tens of degrees of freedom. We show that the dynamics of such a Hermitian system demonstrate a transition, which occurs at the coupling strength between oscillators corresponding to the EP in the non-Hermitian system. This transition manifests itself even in the non-Markovian regime of the system dynamics in which collapses and revivals of the energy occur. Thus, we demonstrate that the phase transition occurring at the passing over the EP in the non-Hermitian system manifests itself in the Hermitian system at all time. We discuss the experimental scheme to observe the signature of EP phase transition in the non-Markovian regime.

description: According to the magnetoshperic accretion scenario, during their evo-

lution, Classical T Tauri stars accrete material from their circumstellar

disk. The accretion process is regulated by the stellar magnetic eld and

produces hot and dense post-shocks on the stellar surface as a result of

impacts of the downfalling material. The impact regions are expected

to strongly radiate in UV and X-rays. Several lines of evidence support

the magnetospheric accretion scenario, especially in optical and infrared

bands. However several points still remain unclear as, for instance,where

the complex-pro le UV lines originate, or whether and how UV and X-ray

emission is produced in the same shock region. The analysis of a large

solar eruption has shown that EUV excesses might be e ectively produced

by the impact of dense fragments onto the stellar surface. Since a steady

accretion stream does not reprouce observations, in this work we investi-

gate the e ects of a fragmented accretion stream on the

uxes and pro les

of C IV and O VIII emission lines. To this end we model the impact of a

fragmented accretion stream onto the chromosphere of a CTTS with 2D

axysimmetric magneto-hydrodynamic simulations. Our model takes into

account of the gravity, the stellar magnetic eld, the thermal conduction

and the radiative cooling from an optically thin plasma.

From the model results, we synthesize the UV and X-ray emission

including the e ect of Doppler shift along the line of sight. We nd that

a fragmented accretion stream produces complex pro les of UV emission

lines which consists of multiple components with di erent Doppler shifts.

Our model predicts line pro les that are consistent with those observed

and explain their origin as due to the stream fragmentation.

description: We consider the Random-Cluster model on $\mathbb{Z}^d$ with interactions of infinite range of the form $J_x = ψ(x)\mathsf{e}^{-ρ(x)}$ with $ρ$ a norm on $\mathbb{Z}^d$ and $ψ$ a subexponential correction. We first provide an optimal criterion ensuring the existence of a nontrivial saturation regime (that is, the existence of $β_{\rm sat}(s)>0$ such that the inverse correlation length in the direction $s$ is constant on $[0,β_{\rm sat}(s))$), thus removing a regularity assumption used in a previous work of ours. Then, under suitable assumptions, we derive sharp asymptotics (which are not of Ornstein-Zernike form) for the two-point function in the whole saturation regime $(0,β_{\rm sat}(s))$. We also obtain a number of additional results for this class of models, including sharpness of the phase transition, mixing above the critical temperature and the strict monotonicity of the inverse correlation length in $β$ in the regime $(β_{\rm sat}(s), β_{\rm c})$.

description: Trying to connect a fundamentally non-commutative spacetime with the conservative perturbative approach to quantum gravity, we are led to the natural question: are non-commutative geometrical effects already present in the regime where perturbative quantum gravity provides a predictive framework? Moreover, is it necessary to introduce non-commutativity by hand, or does it arise through quantum-gravitational effects? We show that the first question can be answered in the affirmative, and the second one in the negative: perturbative quantum gravity predicts non-commutativity at the Planck scale, once one clarifies the structure of observables in the quantum theory.
