description: Prussian blue analogues (PBAs) are a broad and important family of microporous inorganic solids, famous for their gas storage, metal-ion immobilisation, proton conduction, and stimuli-dependent magnetic, electronic and optical properties. The family also includes the widely-used double-metal cyanide (DMC) catalysts and the topical hexacyanoferrate/hexacyanomanganate (HCF/HCM) battery materials. Central to the various physical properties of PBAs is the ability to transport mass reversibly, a process made possible by structural vacancies. Normally presumed random, vacancy arrangements are actually crucially important because they control the connectivity of the micropore network, and hence diffusivity and adsorption profiles. The long-standing obstacle to characterising PBA vacancy networks has always been the relative inaccessibility of single-crystal samples. Here we report the growth of single crystals of a range of PBAs. By measuring and interpreting their X-ray diffuse scattering patterns, we identify for the first time a striking diversity of non-random vacancy arrangements that is hidden from conventional crystallographic analysis of powder samples. Moreover, we show that this unexpected phase complexity can be understood in terms of a remarkably simple microscopic model based on local rules of electroneutrality and centrosymmetry. The hidden phase boundaries that emerge demarcate vacancy-network polymorphs with profoundly different micropore characteristics. Our results establish a clear foundation for correlated defect engineering in PBAs as a means of controlling storage capacity, anisotropy, and transport efficiency.

description: A simple experimentally accessible realization of current rectification by molecules (molecular films) bridging metal electrodes is described. It is based on the spatial asymmetry of the molecule and requires only one resonant conducting molecular level (pi-orbital). The rectification, which is due to asymmetric coupling of the level to the electrodes by tunnel barriers, is largely independent of the work function difference between the two electrodes. Results of extensive numerical studies of the family of suggested molecular rectifiers HS-(CH2)_m-C6H4-(CH2)_n-SH are presented. The highest rectification ratio ~500 is achieved at m = 2 and n = 10.

description: This paper provides microeconomic evidence on food security impacts of privately organized biofuel outgrower schemes in Ethiopia. We conducted a household and community level survey and evaluated the impact of castor bean farming. We use endogenous switching regressions to analyze the impact on food security. Food security (as measured by a “food gap”) and food caloric intake is significantly better in households producing castor beans. “Fuel” and “food” are complements rather than substitutes at the micro-level in castor production in Ethiopia.

description: Long-distance transport of spin information in insulators without long-range magnetic order has been recently reported. Here, we perform a complete characterization of amorphous Y$_3$Fe$_5$O$_{12}$ (a-YIG) films grown on top of SiO$_2$. We confirm a clear amorphous structure and paramagnetic behavior of our a-YIG films, with semiconducting behavior resistivity that strongly decays with increasing temperature. The non-local transport measurements show a signal which is not compatible with spin transport and can be attributed to the drop of the a-YIG resistivity caused by Joule heating. Our results emphasize that exploring spin transport in amorphous materials requires careful procedures in order to exclude the charge contribution from the spin transport signals.

Eikonal quasinormal modes of black holes beyond general relativity II: generalised scalar-tensor perturbations

description: Black hole `spectroscopy', i.e. the identification of quasinormal mode frequencies via gravitational wave observations, is a powerful technique for testing the general relativistic nature of black holes. In theories of gravity beyond general relativity perturbed black holes are typically described by a set of coupled wave equations for the tensorial field and the extra scalar/vector degrees of freedom, thus leading to a theory-specific quasinormal mode spectrum. In this paper we use the eikonal/geometric optics approximation to obtain analytic formulae for the frequency and damping rate of the fundamental quasinormal mode of a generalised, theory-agnostic system of equations describing coupled scalar-tensor perturbations of spherically symmetric black holes. Representing an extension of our recent work, the present model includes a massive scalar field, couplings through the field derivatives and first-order frame dragging rotational corrections. Moving away from spherical symmetry, we consider the simple model of the scalar wave equation in a general stationary-axisymmetric spacetime and use the eikonal approximation to compute the quasinormal modes associated with equatorial and nonequatorial photon rings.

Complete evolution equation for the joint amplitude in photon-pair generation

description: As four-wave-mixing-based photon-pair sources mature, accurate modelling of the photon-pair properties becomes important. Unlike spontaneous parametric down-conversion, four-wave mixing is accompanied by a number of parasitic effects such as nonlinear phase modulation. Currently, most modelling of photon-pair states are analytic in nature, which limits the number and type of effects that can be taken into account. In this work, we derive a complete, dual-pump evolution equation for the joint amplitude of photon pairs, wherein any desired effects can be included. We describe how to efficiently obtain numerical solution to this equation using a split-step approach. Lastly, we cover a few analytical solutions and compare two schemes for pure-photon generation under three different parasitic effects. We show how one scheme is highly sensitive to parasitic effects, while the other is very robust.

description: We present the most continuous data base of optical $BVR_{c}I_{c}$ observations ever published on the BL Lacertae object GC 0109+224, collected mainly by the robotic telescope of the Perugia University Observatory in the period November 1994-February 2002. These observations have been complemented by data from the Torino Observatory, collected in the period July 1995-January 1999, and Mt. Maidanak Observatory (December 2000). GC 0109+224 showed rapid optical variations and six major outbursts were observed at the beginning and end of 1996, in fall 1998, at the beginning and at the end of 2000, and at the beginning of 2002. Fast and large-amplitude drops characterized its flux behaviour. The $R_c$ magnitude ranged from 13.3 (16.16 mJy) to 16.46 (0.8 mJy), with a mean value of 14.9 (3.38 mJy). In the periods where we collected multi-filter observations, we analyzed colour and spectral indexes, and the variability patterns during some flares. The long-term behaviour seems approximatively achromatic, but during some isolated outbursts we found evidence of the typical loop-like hysteresis behaviour, suggesting that rapid optical variability is dominated by non-thermal cooling of a single emitting particle population. We performed also a statistical analysis of the data, through the discrete correlation function (DCF), the structure function (SF), and the Lomb-Scargle periodogram, to identify characteristic times scales, from days to months, in the light curves, and to quantify the mode of variability. We also include the reconstruction of the historical light curve and a photometric calibration of comparison stars, to favour further extensive optical monitoring of this interesting blazar.

description: Previous studies have measured market power when firms consider the consequences of their actions on profits when deciding how much to produce or purchase or both. In contrast, this study illustrates how to measure the exercise of market power when growers collectively control the quantities sold to a market use via a Federal marketing order but exert no control on the quantities produced. The hypothesis that California-Arizona navel orange growers exercised some market power (but not complete monopolistic power) before 1983 could not be rejected. Growers exercised less market power from 1983 on when a USDA policy change curtailed growers' use of marketing order volume controls.

Probing d-wave pairing correlations in the pseudogap regime of the cuprate superconductors via low-energy states near impurities

description: The issue of probing the pseudogap regime of the cuprate superconductors, specifically with regard to the existence and nature of superconducting pairing correlations of d-wave symmetry, is explored theoretically. It is shown that if the d-wave correlations believed to describe the superconducting state persist into the pseudogap regime, but with pair-potential phase-fluctuations that destroy their long-range nature, then the low-energy quasiparticle states observed near extended impurities in the truly superconducting state should also persist as resonances in the pseudogap regime. The scattering of quasiparticles by these phase-fluctuations broadens what was (in the superconducting state) a sharp peak in the single-particle spectral function at low energy, as we demonstrate within the context of a simple model. This peak and its broadening is, in principle, accessible via scanning tunneling spectroscopy near extended impurities in the pseudogap regime. If so, such experiments would provide a probe of the extent to which d-wave superconducting correlations persist upon entering the pseudogap regime, thus providing a stringent diagnostic of the phase-fluctuation scenario.

description: The aim of this paper is to evaluate the impact of collective marketing by FO on cocoa farmer’s price in Cameroun. This evaluation is done through the non-experimental method of impact evaluation which uses the techniques of “Propensity Score Matching”. Data used come from 2006 IITA cocoa baseline survey conducted between March 15 and April 15, 2006 and concern 601 cocoa farmers in Centre region in Cameroon during the 2005/2006 season. Results show that collective marketing has a positive and statistically significant effect on the net price received by farmers. This effect is estimated at 44 FCFA per kilogram of cocoa sold collectively, that means 8% increase on the individual sale price. The main recommendation is to promote the development of FO and collective marketing within FO. The development of FO requires a government policy to support the creation of FOs and by extension the effects of collective sales. Development of collective marketing can be done through creation of credit systems by FO to encourage farmers who sell to individual buyers under the constraint of credit received. This probably would increase significantly the share of supply captured by FO.
Large-S approach to chiral phases in frustrated spin chains

description: A large-S approach to the description of chiral phases in frustrated antiferromagnetic spin-S chains with easy-plane anisotropy is proposed. The approach is valid in the vicinity of the classical Lifshitz point j=1/4, where j is the relative strength of the frustrating next-nearest-neighbor coupling. The effective theory turns out to be the nonlinear sigma-model with the additional fourth-order term in spatial derivatives. The topological term persists for j>1/4, which leads to disappearance of the chiral gapped phase for half-integer S, in accordance with the recent numerical results.

description: The national total expenditure of a country is precipitated on several factors of which revenue generated could be one and very significant. This paper therefore examines the contribution of some selected sources of Nigerian government revenue to total national expenditure. Secondary data sourced and collected from Nigerian Statistical Bulletin of the Central Bank for a period of thirty nine (39) years were used. Statistical and econometric techniques used for the data analysis are unit root test, cointegration test and the error correction model (ECM). Results showed that the original variables are non stationary but are stationary at first difference. Further investigations resulted into the use of the error correction model whose parameters’ estimation was improved by the use of Feasible Generalized Linear (FGLS) Estimator. Findings revealed significant contribution of oil revenue, federation account (federal allocation) and federal retained revenue to the Nigeria total expenditure and that Nigeria may need to be very cautious as non-availability of revenue from these sources points to non-expenditure. These become very essential if the country will have to achieve its developmental goals and objectives towards development and economic growth, among other things.
A Polarization Survey of SiO Maser Variability in Evolved Stars

description: We have monitored the SiO (v = 1, J = 2 -> 1) maser polarization in 17 variable stars (Miras, OH-IR stars, and supergiants) to investigate the long-term persistence of masers. The 8 epochs of observations span 2.5 years, thereby sampling multiple cycles for these stars with typical periods of ~1 year. The average polarization was 23% with a typical dispersion of 7%, although the variability differed substantially from star to star. In the Stokes q and u spectra of individual stars, a few strong maser features tended to dominate the polarization, with the maser features persisting for less than one stellar cycle for some stars, and for multiple cycles for a few stars. Because individual masers are not resolved in our beam-averaged total intensity spectra, we correlated the polarization spectra between epochs to measure the characteristic lifetimes of the features rather than attempting to trace the evolution of separate line components. We found that individual maser feature lifetimes ranged from a few months or less to >2 years. These data indicate that for the sample of stars as a whole, the masers are not reset at a particular stellar phase.

description: In light of recent developments in nearly AdS$_2$ holography, we revisit the semi-classical version of two-dimensional dilaton gravity proposed by Callan, Giddings, Harvey, and Strominger (CGHS) in the early 90's. In distinction to the classical model, the quantum corrected CGHS model has an AdS$_2$ vacuum with a constant dilaton. By turning on a non-normalizable mode of the Liouville field, i.e. the conformal mode of the $2d$ gravity, the explicit breaking of the scale invariance renders the AdS$_2$ vacuum nearly AdS$_2$. As a consequence, there emerges an effective one-dimensional Schwarzian-type theory of pseudo Nambu-Goldstone mode - the boundary graviton - on the boundary of the nearly AdS$_2$ space. We go beyond the linear order perturbation in non-normalizable fluctuations of the Liouville field and work up to the second order. As a main result of our analysis, we clarify the role of the boundary graviton in the holographic framework and show the Virasoro/Schwarzian correspondence, namely that the $2d$ bulk Virasoro constraints are equivalent to the graviton equation of motion of the $1d$ boundary theory, at least, on the $SL(2,R)$ invariant vacuum.

description: The emergence and spread of multidrug-resistant (MDR) pathogenic bacteria is a clinical problem that requires novel anti-infective agents. Targeting pathogenic biofilms is considered a promising strategy to control bacterial infections. In this study, bioactive extracts of Carum copticum were investigated for their anti-biofilm efficacy against extended spectrum β-lactamase (ESβL) producing MDR enteric bacteria. Thymol was also tested for its anti-biofilm properties, as gas chromatography-mass spectrometry revealed a high content (65.8%) of this phytochemical in the C. copticum methanolic extract. Biofilm inhibition was assessed in microtitre plates and further validated by light, electron and confocal laser microscopy. Sub-inhibitory concentrations of bioactive extracts of C. copticum and thymol significantly prevented biofilm development, ranging from 78.6 to 83.9% reductions. Microscopic analysis revealed that biofilms made by ESβL producing MDR enteric bacteria had a weakened structure, scattered microcolonies, and reduced cell density and thickness after exposure to the bioactive extracts and thymol.

description: Electrical conductivity is one of the most commonly used geophysical method for reservoir and environmental studies. Its main interest lies in its sensitivity to key properties of storage and transport in porous media. Its quantitative use therefore depends on the efficiency of the petrophysical relationship to link them. In this work, we develop a new physically based model for estimating electrical conductivity of saturated porous media. The model is derived assuming that the porous media is represented by a bundle of tortuous capillary tubes with a fractal pore-size distribution. The model is expressed in terms of the porosity, electrical conductivity of the pore liquid and the microstructural parameters of porous media. It takes into account the interface properties between minerals and pore water by introducing a surface conductivity. Expressions for the formation factor and hydraulic tortuosity are also obtained from the model derivation. The model is then successfully compared with published data and performs better than previous models. The proposed approach also permits to relate the electrical conductivity to other transport properties such as the hydraulic conductivity.

description: The aim of the hadron physics research programs conducted at J-PARC is to explore the structure of hadronic matter using the world's highest-intensity meson beams. Since the first beam was extracted at the hadron experimental facility (HEF) in February 2009, a wide variety of physics experiments have been proposed and performed to address open questions regarding quantum chromodynamics (QCD) at low energy. The high-intensity $K^-$ and high-momentum beams available at J-PARC open a new era in hadron and nuclear physics, in which strange and charm quarks play an important role. We review the programs focused on addressing the hadron structure as strongly interacting composite particles, the origin of hadron mass, and interactions between hadrons under broken flavor SU(3) symmetry.

description: We study the cosmological consequences of interacting Tsallis holographic dark energy model in the framework of the fractal universe, in which, the Hubble radius is considered as the IR cut-off. We drive the equation of state (EoS) parameter, deceleration parameter and the evolution equation for the Tsallis holographic dark energy density parameter. Our study shows that this model can describe the current accelerating Universe in both noninteracting and interacting scenarios, and also a transition occurs from the deceleration phase to the accelerated phase, at the late time. Finally, we check the compatibility of free parameters of the model with the latest observational results by using the Pantheon supernovae data, eBOSS, 6df, BOSS DR12, CMB Planck 2015, Gamma-Ray Burst.

description: We have created a Bose-Einstein condensate of 87Rb atoms directly in an optical trap. We employ a quasi-electrostatic dipole force trap formed by two crossed CO_2 laser beams. Loading directly from a sub-doppler laser-cooled cloud of atoms results in initial phase space densities of ~1/200. Evaporatively cooling through the BEC transition is achieved by lowering the power in the trapping beams over ~ 2 s. The resulting condensates are F=1 spinors with 3.5 x 10^4 atoms distributed between the m_F = (-1,0,1) states.

Mitigation of tipping point transitions by time-delay feedback control

description: In stochastic multistable systems driven by the gradient of a potential, transitions between equilibria is possible because of noise. We study the ability of linear delay feedback control to mitigate these transitions, ensuring that the system stays near a desirable equilibrium. For small delays, we show that the control term has two effects: i) a stabilizing effect by deepening the potential well around the desirable equilibrium, and ii) a destabilizing effect by intensifying the noise by a factor of $(1-τα)^{-1/2}$, where $τ$ and $α$ denote the delay and the control gain, respectively. As a result, successful mitigation depends on the competition between these two factors. We also derive analytical results that elucidate the choice of the appropriate control gain and delay that ensure successful mitigations. These results eliminate the need for any Monte Carlo simulations of the stochastic differential equations, and therefore significantly reduce the computational cost of determining the suitable control parameters. We demonstrate the application of our results on two examples.

Year: 2024

description: The article explores the psychological aspects of fostering motivation to study among students within modern educational systems. Motivation plays a crucial role in academic success, and understanding the psychological factors that influence it is key to effective learning. The article reviews fundamental motivation theories, such as Maslow’s hierarchy of needs and self-determination theory, and examines how personal characteristics, emotional factors, and psychological barriers impact students' motivation. Additionally, the influence of modern educational systems, including the integration of digital technologies and hybrid learning models, on motivation is analyzed. The study highlights various psychological and pedagogical strategies for enhancing and sustaining students' motivation, emphasizing the importance of self-regulation and a supportive learning environment.
In vitro assessment of inter-kingdom biofilm formation by bacteria and filamentous fungi isolated from a drinking water distribution system

description: The main focus so far in the study of biofilm formation in drinking water has been bacteria. Studies on biofilm formation involving filamentous fungi are, therefore, scarce. This study aimed to assess and characterize the ability of these microorganisms to interact with bacteria whilst forming inter-kingdom biofilms. Biofilms were analysed in terms of total biomass, metabolic activity, bacterial colony forming units and morphology by epifluorescence microscopy. The quantitative methods revealed that biofilm mass increased over time for both single and inter-kingdom biofilms, while specific metabolic activity decreased, in general, along the time points evaluated. Microscopic data visually confirmed the biofilm mass increase over time. This study shows that fungal stage development is important in the first 24 h of biofilm formation. Inter-kingdom biofilm formation is microorganism dependent and inter-kingdom biofilms may provide an advantage to the opportunistic bacterium Acinetobacter calcoaceticus to replicate and proliferate when compared with Methylobacterium oryzae.

description: Abstract

With the continuous development of intellectual property, China has gradually forged a path to intellectual property development with Chinese characteristics. Significant achievements have been made in the cultivation of intellectual property talent; however, there remain prominent issues related to talent structure, quality, and attrition. The main reason for these challenges lies in the current training model for intellectual property talent, which is often vague and one-dimensional, with rigid and singular training entities. Therefore, it is essential to clarify the scope of high-level intellectual property talent, seize the opportunity for integrating industry, education, and research, collaboratively reshape training concepts, refine training methods, and explore innovations and transformations in the training mechanism for intellectual property talent.
title: Möglichkeiten der Mitarbeiterbindung von MitarbeiterInnen der Generation Z an steirische KFZ-Betriebe

Subjects: subject: 658 Allgemeines Management

description: Die steirische KFZ-Wirtschaft steht vor einer großen personellen Herausforderung. Der Mangel an Fachkräften wird durch zwei Dinge stark befeuert. Zum einen der demografischen Wandel und zum anderen der Wunsch nachrückender ArbeitnehmerInnen-Generationen weniger Arbeitsstunden leisten zu müssen. Dieses Problem wird durch den oftmals vorhandenen monetären Background der Vorgenerationen verstärkt, da dieser die Aufnahme von Krediten für eine etwaige Eigenheimbeschaffung hinfällig macht. Es ist somit eine zentrale Frage, die sich Unternehmen stellen müssen, wie es möglich ist, MitarbeiterInnen für das eigene Unternehmen zu gewinnen und an dieses zu binden. Dazu sind verschiedene Maßnahmen erforderlich. Diese Masterarbeit befasst sich damit, wie das Halten von MitarbeiterInnen der Generation Z aktuell möglich ist und auch in Zukunft zu bewerkstelligen sein wird. Dazu wurden speziell die Relevanz der direkten Führungskraft, die Wertehaltung des Unternehmens und die Bedürfnisse der Generation Z als wesentliche Bausteine herausgearbeitet. Wichtig dabei ist es, dass langfristige Mitarbeiterbindung nur durch einen Mix aus Maßnahmen möglich ist. Einzelne Entscheidungen oder Maßnahmen werden nur zu kurzzeitigen Verbesserungen führen oder können im schlimmsten Fall sogar Verschlechterungen hervorbringen. Somit ist es für jedes Unternehmen als essenziell anzusehen sich mit sich selbst zu beschäftigen und den Mitarbeitenden kennenzulernen und in den Fokus zu stellen. Wörter wie Employer Branding oder betriebliche Gesundheitsförderung dürfen für EntscheidungsträgerInnen kein unbekanntes Terrain darstellen, sondern müssen bereits jetzt im betrieblichen Alltag Beachtung finden. Diese Masterarbeit gibt somit einen Überblick über einzelne Maßnahmen, die als erfolgsversprechend einzustufen sind, aber auch über die Charakteristika der Generation Z, die bei der Wahl der Maßnahmen im Auge behalten werden sollen. Am Ende dieser Arbeit ist es dem/r LeserIn möglich die Mitarbeitenden der Genration Z besser zu verstehen und die Relevanz der Mitarbeiterbindung in einem Unternehmen einschätzen zu können. Weiters werden einige, in der Praxis als funktionierende, bewährte Tools vorgestellt, die rasch im eigenen Betrieb umgesetzt werden können.

description: We explain how the usual algebras of Feynman diagrams behave under the grope degree introduced in "Grope cobordism of classical knots." We show that the Kontsevich integral rationally classifies grope cobordisms of knots in 3-space when the ``class'' is used to organize gropes. This implies that the grope cobordism equivalence relations are highly nontrivial in dimension three. We also show that the class is not a useful organizing complexity in four dimensions since only the Arf invariant survives. In contrast, measuring gropes according to ``height'' does lead to very interesting four-dimensional information (Cochran-Orr-Teichner). Finally, several low degree calculations are explained, in particular we show that S-equivalence is the same relation as grope cobordism based on the smallest tree with an internal vertex.

description: The stability of a Bose condensed gas with a negative scattering length is studied with regard to the role played by the initial state. A trapped ideal gas ground state is shown to be unstable when the Gross Pitaevskii equation still predicts the existence of a stable state. A possible relation to a recent experimental study of the critical conditions for stability or collapse of a Bose Einstein condensate [J.L. Roberts et al., Phys. Rev. Lett. 86, 4211 (2001)] is discussed.
