title: Forschungskooperationen zwischen Universitäten und Unternehmen: Eine Betrachtung auf Organisationsebene und Projektebene
Creators: name: Gretsch, Oliver
Publisher: name: UNSPECIFIED
Year: 2021

description: Für Unternehmen bieten Forschungskooperationen mit Universitäten (UIC) den Zugang zu komplementären Ressourcen, neuem Wissen und Technologien. Die unterschiedlichen organisationalen Hintergründe setzen jedoch Barrieren für die Zusammenarbeit. Es ist daher aus der Forschungssicht und der Managementperspektive relevant, ein vertieftes Verständnis für die organisationalen Bedingungen und die projektbezogenen Managementaktivitäten zu entwickeln, die den Erfolg in UIC-Projekten beeinflussen. Zudem werden Kontingenzfaktoren betrachtet, die Auswirkungen auf das Management der UIC haben. Es wird untersucht, wie organisations- und projektbezogene Einflussfaktoren miteinander interagieren und es werden Mechanismen aufgezeigt, wie UIC-Projekte erfolgreich gemanagt werden können. Die Dissertation baut auf vier Studien mit vier verschiedenen Datensätzen auf. In Studie 1 werden die kritischen Managementaktivitäten in UIC-Projekten und treibende organisations- sowie projektbezogene Einflussfaktoren untersucht. Die Resultate werden in einem konzeptionellen Modell mit Propositionen für ein effektives Management der UIC-Projekte zusammengefasst. Die Effekte der parallelen Zusammenarbeit eines Unternehmens sowohl in UIC als auch mit marktbasierten Akteuren werden in Studie 2 betrachtet. Die Befunde zeigen, dass die Partnerauswahl und die Wirksamkeit der Zusammenarbeit von dem Innovationsgrad abhängen können. Für hochinnovative Forschungsvorhaben können Unternehmen von der parallelen Zusammenarbeit mit Universitäten und Unternehmen in der sehr frühen Innovationsphase profitieren. In Studie 3 wird die geteilte Wahrnehmung der Innovationsherausforderung in UIC und deren Wirkung auf den Projekterfolg untersucht. Die Resultate zeigen, dass die formelle Projektsteuerung hilft, mit der Ungewissheit explorativer Forschungsvorhaben umzugehen. Besonders die informelle Projektsteuerung unterstützt die Partner, eine geteilte Wahrnehmung zu entwickeln und die Forschungsaufgaben gemeinsam zu bewältigen. Für die unternehmensseitige Aggressivität der Intellectual Property (IP)-Strategie wird in Studie 4 verdeutlicht, dass hauptsächlich informelle Mechanismen der Projektsteuerung die potenziell negativen Effekte dieser Unternehmensstrategie abschwächen helfen, wohingegen formelle Steuerungsmechanismen die Spannungen zwischen den Partnern tendenziell verschärfen. Formelle Steuerungsmechanismen können folglich eine gute Basis für die Zusammenarbeit schaffen, da die Anforderungen und zu erzielenden Resultate festgelegt werden. Informelle Mechanismen der Projektsteuerung schaffen durch eine interaktive Beteiligung und vertrauensvolle Zusammenarbeit allerdings bessere Möglichkeiten zur Überwindung wahrgenommener organisationaler Barrieren und Herausforderungen im Projektfortschritt.

description: This work is devoted to deriving the Onsager-Machlup function for a class of stochastic dynamical systems under (non-Gaussian) Levy noise as well as (Gaussian) Brownian noise, and examining the corresponding most probable paths. This Onsager-Machlup function is the Lagrangian giving the most probable path connecting metastable states for jump-diffusion processes. This is done by applying the Girsanov transformation for measures induced by jump-diffusion processes. Moreover, we have found this Lagrangian function is consistent with the result in the special case of diffusion processes. Finally, we apply this new Onsager-Machlup function to investigate dynamical behaviors analytically and numerically in several examples. These include the transitions from one metastable state to another metastable state in a double-well system, with numerical experiments illustrating most probable transition paths for various noise parameters.

description: We present some evidence that in Lattice Gauge Theory the condensate contains a non-perturbative contribution proportional to $Λ^2$, the square of the physical scale. This result is based on an analysis of the Wilson loop plaquette expectation from Monte Carlo simulations and its perturbative expansion computed to eight loops. The analysis is not fully conclusive since the calculations are done on a finite lattice and one needs an extrapolation to infinite lattice. It has been recently suggested that in the gluon condensate a $Λ^2$-contribution could be present coming from the large momentum behaviour of the running coupling and not connected to operator product expansion.

Subjects: HEV, foodborne viruses, pigs

description: Aim: The aim of the literature review is to summarize current data on the prevalence of Hepatitis E virus (HEV) in human and
 pig population in Bulgaria to 2021. This review is based on reported cases of prevalence of HEV in hospitalized humans and
 prevalence of HEV infection in different groups of pig population in Bulgaria.
 Methods: The scientific papers and reviews, published in PubMed Databases and Bulgarian medical databases, were analyzed.
 Data on the prevalence of Hepatitis E virus in Bulgaria from January 1995 to December 2020 were summarized.
 Results: During the period (1995-2020) it was a 16 paper about prevalence of HEV in human and pig population in Bulgaria.
 They have been reported 6247 blood serums from hospitalized patients and 1381 serum samples from pigs at different ages
 were tested. In total 923 samples (14.7 %) from the hospitalized patients were positive for HEV. AntiHEV-IgG were found in 820
 specimens (88.8 %) and HEV-RNA was present in 103 of those (11.2 %). The first data for HEV in pigs in Bulgaria were published
 in 2017. In total 846 from 1381 pig serum samples (61.2 %) were positive for antiHev-IgG. Of these, 52 samples (6.1 %) were
 from wild boar.
 Conclusions: The spread of HEV among the populations of humans and pigs in Bulgaria is worrying. The data from the literature
 review are insufficient to establish the relationship between the virus in humans and pigs in Bulgaria. The hepatitis E virus needs
 to be considered in the differential diagnosis of acute human hepatitis. The question of its usefulness as an indicator of pork
 food safety is also debatable. The development of a unified harmonized strategy for monitoring and control of this zoonotic
 agent is imperative.

description: We develop a theory for the quantum vortex glass, with both the coupling strengths and the site energies disordered. This model is closely related to XY spin glasses and bosons in random media. For properly chosen distributions of the site disorder the phase diagram consists of a superfluid phase, and Weak and Strong Glass regions, dominated by long range and local fluctuations, respectively. The most direct experimental manifestation of the Strong Glass transition is the lack of divergence of the corresponding non-linear susceptibility.

New universal Lyapunov functions for non-linear reaction networks

Subjects: subject: Chemical Physics (physics.chem-ph)

description: In 1961, Rényi discovered a rich family of non-classical Lyapunov functions for kinetics of the Markov chains, or, what is the same, for the linear kinetic equations. This family was parameterised by convex functions on the positive semi-axis. After works of Csiszár and Morimoto, these functions became widely known as $f$-divergences or the Csiszár--Morimoto divergences. These Lyapunov functions are universal in the following sense: they depend only on the state of equilibrium, not on the kinetic parameters themselves. Despite many years of research, no such wide family of universal Lyapunov functions has been found for nonlinear reaction networks. For general non-linear networks with detailed or complex balance, the classical thermodynamics potentials remain the only universal Lyapunov functions. We constructed a rich family of new universal Lyapunov functions for {\em any non-linear reaction network} with detailed or complex balance. These functions are parameterised by compact subsets of the projective space. They are universal in the same sense: they depend only on the state of equilibrium and on the network structure, but not on the kinetic parameters themselves. The main elements and operations in the construction of the new Lyapunov functions are partial equilibria of reactions and convex envelopes of families of functions.

The Short Path Algorithm Applied to a Toy Model

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

description: We numerically investigate the performance of the short path optimization algorithm on a toy problem, with the potential chosen to depend only on the total Hamming weight to allow simulation of larger systems. We consider classes of potentials with multiple minima which cause the adiabatic algorithm to experience difficulties with small gaps. The numerical investigation allows us to consider a broader range of parameters than was studied in previous rigorous work on the short path algorithm, and to show that the algorithm can continue to lead to speedups for more general objective functions than those considered before. We find in many cases a polynomial speedup over Grover search. We present a heuristic analytic treatment of choices of these parameters and of scaling of phase transitions in this model.

Theory of Non-Reciprocal Optical Effects in Antiferromagnets: The Case Cr_2O_3

Publisher: name: arXiv

description: A microscopic model of non-reciprocal optical effects in antiferromagnets is developed by considering the case of Cr_2O_3 where such effects have been observed. These effects are due to a direct coupling between light and the antiferromagnetic order parameter. This coupling is mediated by the spin-orbit interaction and involves an interplay between the breaking of inversion symmetry due to the antiferromagnetic order parameter and the trigonal field contribution to the ligand field at the magnetic ion. We evaluate the matrix elements relevant for the non-reciprocal second harmonic generation and gyrotropic birefringence.

description: WIRC+Pol is a newly commissioned low-resolution (R~100), near-infrared (J and H band) spectropolarimetry mode of the Wide-field InfraRed Camera (WIRC) on the 200-inch Hale Telescope at Palomar Observatory. The instrument utilizes a novel polarimeter design based on a quarter-wave plate and a polarization grating (PG), which provides full linear polarization measurements (Stokes I, Q, and U) in one exposure. The PG also has high transmission across the J and H bands. The instrument is situated at the prime focus of an equatorially mounted telescope. As a result, the system only has one reflection in the light path, providing minimal telescope induced polarization. A data reduction pipeline has been developed for WIRC+Pol to produce linear polarization measurements from observations. WIRC+Pol has been on-sky since February 2017. Results from the first year commissioning data show that the instrument has a high dispersion efficiency as expected from the polarization grating. We demonstrate the polarimetric stability of the instrument with RMS variation at 0.2% level over 30 minutes for a bright standard star (J = 8.7). While the spectral extraction is photon noise limited, polarization calibration between sources remain limited by systematics, likely related to gravity dependent pointing effects. We discuss instrumental systematics we have uncovered in the data, their potential causes, along with calibrations that are necessary to eliminate them. We describe a modulator upgrade that will eliminate the slowly varying systematics and provide polarimetric accuracy better than 0.1%.

description: We present new numerical method to compute structures of differentially rotating white dwarfs with thermal stratification. Our models have cores composed of ions and completely degenerate electrons and have isentropic envelopes composed of ions, photons, partially degenerate electrons and positrons. The models are intended to mimic very early phases of remnants of white dwarf binary mergers, some of which may lead to type Ia supernovae. The effect of hot envelope to increase the mass depends on its chemical composition through the mean molecular weight of the envelope. For uniformly rotating models, we see only a small increase in mass even in the presence of hot envelope. Differential rotation changes it drastically and super-Chandrasekhar mass model whose mass doubles the Chandrasekhar mass of the degenerate star for some parameter choices. We also compute quasi-equilibrium evolutionary sequences of remnants by fixing either total angular momentum or entropy in the envelope. Existence of these sequences depends on various factors such as the remnant mass, the profile of differential rotation, the entropy and the chemical composition of the envelope.

description: A simple connection between the universal $R$ matrix of $U_q(sl(2))$ (for spins $\demi$ and $J$) and the required form of the co-product action of the Hilbert space generators of the quantum group symmetry is put forward. This gives an explicit operator realization of the co-product action on the covariant operators. It allows us to derive the quantum group covariance of the fusion and braiding matrices, although it is of a new type: the generators depend upon worldsheet variables, and obey a new central extension of $U_q(sl(2))$ realized by (what we call) fixed point commutation relations. This is explained by showing that the link between the algebra of field transformations and that of the co-product generators is much weaker than previously thought. The central charges of our extended $U_q(sl(2))$ algebra, which includes the Liouville zero-mode momentum in a nontrivial way are related to Virasoro-descendants of unity. We also show how our approach can be used to derive the Hopf algebra structure of the extended quantum-group symmetry $U_q(sl(2))\odot U_{\qhat}(sl(2))$ related to the presence of both of the screening charges of 2D gravity.

The focus is set on the ability of neural networks to extract statistical features from a sequence. We demonstrate that the average power-law behavior is learnable, namely, the sequence generated by the trained network obeys the same statistical behavior. The interplay between a correlated weight matrix and the sequence generated by such a network is explored. A weight matrix with a power-law correlation function along the vertical direction, gives rise to a sequence with a similar statistical behavior.

description: Many scenarios of physics beyond the Standard Model that address the hierarchy problem also predict the existence of vector-like top quark partners, which are generally expected around the TeV scale. In this paper, we propose to search for a vector-like top quark partner with charge $2/3$ in a simplified model including only two free parameters, the coupling constant $g^{\ast}$ and top quark partner mass $m_T$. We investigate the observability of the top quark partner through the process $pp \to T(\to th)j\to t(\to b W^+\to b \ell^{+} ν_{\ell})h( \to WW^{\ast}\to \ell^{+}ν\ell^{-}\barν) j$, where $T$ is the heavy top quark partner and $h$ the SM-like Higgs boson, at the Large Hadron Collider (LHC). The discovery prospects and exclusion limits on the parameter plane defined by ($m_T,g^{\ast}$) are obtained for the already scheduled LHC runs as well as at the future High-Luminosity~LHC (HL-LHC). The constraints and projected sensitivities are also interpreted in a realistic model, i.e., the minimal Composite Higgs Model with singlet top quark partners. We finally also analyze the projected sensitivity in terms of the production cross section times branching fraction at the (HL-)LHC.

Structure functions in the polarized Drell-Yan processes with spin-1/2 and spin-1 hadrons: I. general formalism

description: We discuss general formalism for the structure functions which can be investigated in the polarized Drell-Yan processes with spin-1/2 and spin-1 hadrons. To be specific, the formalism can be applied to the proton-deuteron Drell-Yan processes. Because of the spin-1 nature, there are new structure functions which cannot be studied in the proton-proton reactions. Imposing Hermiticity, parity conservation, and time-reversal invariance, we find that 108 structure functions exist in the Drell-Yan processes. However, the number reduces to 22 after integrating the cross section over the virtual-photon transverse momentum Q_T or after taking the limit Q_T->0. There are 11 new structure functions in addition to the 11 ones in the Drell-Yan processes of spin-1/2 hadrons. The additional structure functions are associated with the tensor structure of the spin-1 hadron, and they could be measured by quadrupole spin asymmetries. For example, the structure functions exist for "intermediate" polarization although their contributions vanish in the longitudinal and transverse polarization reactions. We show a number of spin asymmetries for extracting the polarized structure functions. The proton-deuteron reaction may be realized in the RHIC-Spin project and other future ones, and it could be a new direction of next generation high-energy spin physics.

description: An elastic string embedded in 3D space and subject to a short-range correlated random potential exhibits marginal pinning at high temperatures, with the pinning length $L_c(T)$ becoming exponentially sensitive to temperature. Using a functional renormalization group (FRG) approach we find $L_c(T) \propto \exp[(32/π)(T/T_{\rm dp})^3]$, with $T_{\rm dp}$ the depinning temperature. A slow decay of disorder correlations as it appears in the problem of flux line pinning in superconductors modifies this result, $\ln L_c(T)\propto T^{3/2}$.

description: We apply a Bayesian method to model multi-epoch radial velocity measurements in the ultra-faint dwarf galaxy Reticulum II, fully accounting for the effects of binary orbital motion and systematic offsets between different spectroscopic datasets. We find that the binary fraction of Ret II is higher than 0.5 at the 90% confidence level, if the mean orbital period is assumed to be 30 years or longer. Despite this high binary fraction, we infer a best-fit intrinsic dispersion of 2.8$_{-1.2}^{+0.7}$ km/s, which is smaller than previous estimates, but still indicates Ret II is a dark-matter dominated galaxy. We likewise infer a $\lesssim$ 1% probability that Ret II's dispersion is due to binaries rather than dark matter, corresponding to the regime $M_{\odot}/L_{\odot} \lesssim$ 2. Our inference of a high close binary fraction in Ret II echoes previous results for the Segue 1 ultra-faint dwarf and is consistent with studies of Milky Way halo stars that indicate a high close binary fraction tends to exist in metal-poor environments.

Empowering society by reusing privately held data for official statistics - A European approach
Creators: name: Mitrea, Geta

Year: 2023

description: The present paper is focused on the work of an expert group on ‘Facilitating the use of new data sources for official statistics’ created by Eurostat during March 2021 – May 2022. The main purpose of this expert group was to reflect on new opportunities riced once with our rapidly changing and increasingly data-driven society and make recommendations to enhance the reuse of private sector data in official statistics under the European strategy for data.

In this context the Data Documentation Initiative (DDI) standards could play their relevant role to re-use of data, transparency, data sharing respecting the legal framework and the principles described below.The final report highlights the regulatory gaps, fragmentation of practices, and lack of clarity regarding businesses’ rights and obligations. Voluntary partnerships between businesses and statistical authorities have recently been set up and rolled out, but they have rarely led to sustainable data reuse in the regular production of official statistics. To obtain the maximum benefit for society, the Expert Group proposes to prioritize action in four areas.

First, fair and effective partnerships between businesses and statistical authorities must be promoted on a systematic and regular basis. Such partnerships have to be based on a mutual recognition that it is legitimate for the different parties to have different roles and interests, based on trust, social responsibility.

Second, statistical authorities and private data holders should develop a partnership approach to maximize business incentives and minimize risk, based on mutually agreed operational modalities of data reuse.

Third, the legal framework should set out a clear set of requirements and safeguards for private data holders. Where it is necessary to collect data from private data holders, the data protection framework must be respected, and data subjects' rights must be ensured. The legal framework should also clarify businesses’ rights and obligations regarding data sharing and reuse for statistical purposes, including issues related to ownership, intellectual property rights, and commercial confidentiality.

Fourth, the regulatory framework should enable statistical authorities to access privately held data for statistical purposes while ensuring the data protection framework is respected, data subjects' rights are ensured, and businesses’ interests are protected. The report proposes a model based on the principles of transparency, accountability, proportionality, and risk management.

The expert group and the report have contributed in clarifying several issues related to the use of new data sources for official statistics. And, was used for the Proposal for a REGULATION OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL amending Regulation (EC) No 223/2009 on European statistics. The proposal will be further discussed in the European Parliament and the Council following its journey in the EU legislative process.

description: We have observed interaction effects in the differential conductance $G$ of short, disordered metal bridges in a well-controlled non-equilibrium situation, where the distribution function has a double Fermi step. A logarithmic scaling law is found both for the temperature and for the voltage dependence of $G$ in all samples. The absence of magnetic field dependence and the low dimensionality of our samples allow us to distinguish between several possible interaction effects, proposed recently in nanoscopic samples. The universal scaling curve is explained quantitatively by the theory of electron-electron interaction in diffusive metals, adapted to the present case, where the sample size is smaller than the thermal diffusion length.

Dielectric properties of multiband electron systems: II - Collective modes

description: Starting from the tight-binding dielectric matrix in the random phase approximation we examine the collective modes and electron-hole excitations in a two-band electronic system. For long wavelengths (${\bf q}\rightarrow0$), for which most of the analysis is carried out, the properties of the collective modes are closely related to the symmetry of the atomic orbitals involved in the tight-binding states. In insulators there are only inter-band charge oscillations. If atomic dipolar transitions are allowed, the corresponding collective modes reduce in the asymptotic limit of vanishing bandwidths to Frenkel excitons for an atomic insulator with weak on-site interactions. The finite bandwidths renormalize the dispersion of these modes and introduce a continuum of incoherent inter-band electron-hole excitations. The possible Landau damping of collective modes due to the presence of this continuum is discussed in detail.

Interaction of gated and ungated plasmons in two-dimensional electron systems

description: Unique properties of plasmons in two-dimensional electron systems (2DESs) have been studied for many years. Existing theoretical approaches allow for analytical study of the properties of ungated and gated plasmons in two fundamental, ideal cases - the 2DES in dielectric environment and under an infinite metallic gate, respectively. However, it is for the first time that we introduce an analytical theory of the interaction of gated and ungated plasmons in partly gated 2DES. Generally, a finitewidth gate is formed by a metallic strip placed over an infinite plane hosting 2D electrons. Our solution, in particular, describes the propagating plasmon modes with their charge density having N nodes under the gate. In this regard, a new mode with N = 0 has been found in addition to the gapped modes with N = 1, 2,..., previously derived from numerical calculations. Unexpectedly, this fundamental plasmon mode has been found to differ substantially from the rest. In fact, it is characterised by gapless square root dispersion and represents a hybrid of gated and ungated plasmons. In contrast to the higher modes, the currents and lateral fields of the fundamental mode are localized mainly to the outside area in the vicinity of the gate. Heretofore, such a 'near-gate plasmon' has never been considered.

description: The fermion masses and mixing angles are fitted using only 3 free parameters in a non-supersymmetric extension of the Standard Model, with new approximately conserved chiral gauge quantum numbers broken by a set of Higgs fields. The fundamental mass scale of this anti-grand unification model is given by the Planck mass. We also calculate neutrino mixing angles and masses, as well as CP violation from the CKM matrix. A good fit is obtained to the observed fermion masses but our predictions of the neutrino masses are too small to lead to any observable neutrino oscillation effects claimed today, without introducing another mass scale. We also give some arguments in support of this type of model based on the observed fermion masses.

description: The term "Widening countries" refers to the countries that have recently joined the European Union. These countries have lower research and innovation rates, which makes it difficult for them to contribute fully to a knowledge-based and innovation-driven EU. This category has evolved over time based on the ranking of EU member states in the European competitiveness reports. Under Horizon Europe, the Widening category includes EU-13 countries, Greece, and Portugal, along with EU's outermost regions and 14 associate countries from Eastern Europe, the Caucasus, and Northern Africa.

 

Despite their diversity, Central and Eastern European countries share several challenges in terms of research intensiveness and gender equality. Widening countries, in general, and those from CEE, score below the EU average on gender equality indexes. The current situation of gender inequality in each country depends on socially and historically constructed local arrangements, as well as recent political processes such as the transition from authoritarian rule or state socialism, and Europeanisation. This largely accounts for the variety of gender equality regimes in the EU, as well as different R&I settings in terms of (infra)structures, fields of specialisation, or work cultures.

description: We present the analytic solution of the Mode III steady-state crack in a square lattice with piecewise linear springs and Kelvin viscosity. We show how the results simplify in the limit of large width. We relate our results to a model where the continuum limit is taken only along the crack direction. We present results for small velocity, and for large viscosity, and discuss the structure of the critical bifurcation for small velocity. We compute the size of the process zone wherein standard continuum elasticity theory breaks down.

description: Microscopically conserving reduced models of many-body systems have a long, highly successful history. Established theories of this type are the random-phase approximation for Coulomb fluids and the particle-particle ladder model for nuclear matter. There are also more physically comprehensive approximations such as the induced-interaction and parquet theories. Notwithstanding their explanatory power, some theories have lacked an explicit Hamiltonian from which all significant system properties, static and dynamic, emerge canonically. This absence can complicate evaluation of the conserving sum rules, essential consistency checks on the validity of any model. In a series of papers Kraichnan introduced a stochastic embedding procedure to generate explicit Hamiltonians for common approximations for the full many-body problem. Existence of a Hamiltonian greatly eases the task of securing fundamental identities in such models. I revisit Kraichnan's method to apply it to correlation theories for which such a canonical framework has not been available. I exhibit Hamiltonians for more elaborate correlated models incorporating both long-range screening and short-range scattering phenomena. These are relevant to the study of strongly interacting electrons and condensed quantum systems broadly.
