description: The genetic code underlying protein synthesis is a canonical example of a degenerate biological system. Degeneracies in physical and biological systems can be lifted by external perturbations thus allowing degenerate systems to exhibit a wide range of behaviors. Here we show that the degeneracy of the genetic code is lifted by environmental perturbations to regulate protein levels in living cells. By measuring protein synthesis rates from a synthetic reporter library in Escherichia coli, we find that environmental perturbations, such as reduction of cognate amino acid supply, lift the degeneracy of the genetic code by splitting codon families into a hierarchy of robust and sensitive synonymous codons. Rates of protein synthesis associated with robust codons are up to hundred-fold higher than those associated with sensitive codons under these conditions. We find that the observed hierarchy between synonymous codons is not determined by usual rules associated with tRNA abundance and codon usage. Rather, competition among tRNA isoacceptors for aminoacylation underlies the robustness of protein synthesis. Remarkably, the hierarchy established using the synthetic library also explains the measured robustness of synthesis for endogenous proteins in E. coli. We further found that the same hierarchy is reflected in the fitness cost of synonymous mutations in amino acid biosynthesis genes and in the transcriptional control of sigma factor genes. Our study reveals that the degeneracy of the genetic code can be lifted by environmental perturbations, and it suggests that organisms can exploit degeneracy lifting as a general strategy to adapt protein synthesis to their environment.

description: We present a detailed pulse phase resolved spectral analysis of the persistent high mass X-ray binary pulsar Vela X-1 observed with Suzaku during June 2008. The pulse profiles exhibit both intensity and energy dependence with multiple peaks at low energies and double peaks at higher energies. The source shows some spectral evolution over the duration of the observation and care has been taken to average over data with minimum spectral variability for the analysis. We model the continuum with a phenomenological partial covering high energy cutoff model and a more physical partial covering thermal Comptonization model (CompTT) excluding the time ranges having variable hardness ratio and intensity dependence. For both the models we detect a cyclotron resonant scattering feature (CRSF) and its harmonic at ~ 25 keV and ~ 50 keV. Both the CRSF fundamental and harmonics parameters are strongly variable over the pulse phase, with the ratio of the two line energies deviating from the classical value of 2. The continuum parameters also show significant variation over the pulse phase and give us some idea about the changing physical conditions that is seen with the changing viewing angle at different pulse phases and obscuration by the accretion stream at some pulse phases.

description: Solar-like oscillating giants observed by the space-borne satellites CoRoT and Kepler can be used as key tracers of stellar populations in the Milky Way. When combined with additional photometric/spectroscopic constraints, the pulsation spectra of solar-like oscillating giant stars not only reveal their radii, and hence distances, but also provide well-constrained estimates of their masses, which can be used as proxies for the ages of these evolved stars. In this contribution we provide supplementary material to the comparison we presented in Miglio et al. (2013) between populations of giants observed by CoRoT in the fields designated LRc01 and LRa01.

Creators: name: DeLacey, Virginia Sasser

description: While American, British, and French reactions to the American Revolution are well-known, those of the German people are not, despite the presence of almost 30,000 German soldiers in America fighting for the British army and hundreds of German volunteers fighting for the American patriots. The participation of German soldiers on both sides of the conflict inspired numerous works of German poetry, prose, and drama, all largely forgotten in the wake of the French Revolution and the rise of German Classicism and Romanticism. This thesis examines two works that have received brief mention in the past two centuries: Der hessische Officier in Amerika, a 1783 play by the Gotttingen lawyer and poet Johann August Weppen, and Reizenstein: Die Geschichte eines deutschen Officier, an epistolary novel in two volumes written by the Swabian classics scholar and teacher David Christoph Seybold that was published anonymously in 1778 and 1779. Analysis of these texts suggests that German involvement in the American Revolution led German writers to reevaluate their perceptions of America in light of new information that was being sent home by the soldiers serving there and news reports about the conflict that were being published in German newspapers. These works reflect the popular discourse about America that was being carried on throughout the German territories, reveal the political climate in the areas in which they were written, and show how America and the American Revolution were used to register German idealism and discontent. Weppen and Seybold contributed to a dynamic Amerikabild, or image of America, that developed in Germany during the American Revolution. This Amerikabild contrasted with the static views of America offered in pre- and post-Revolutionary literature about America, including the 1776 play Die Werbung für England by Johann Christoph Krauseneck and the 1798 novel Der Unglückliche Walter by I. Maillard, which this thesis will briefly consider for purposes of comparison.

description: Sound-related behavioural studies explore the effects of sound on underwater animals in tanks under controlled laboratory conditions. In this study, we aim to assess sound pressure distributions and gradients in a small-sized water-filled tank that can be used in behavioural studies to examine anthropogenic sound effects on fish and invertebrates and to raise awareness among scientists in the field of underwater acoustics. To assess sound pressure, a water-filled fish tank was used with dimensions of 35*30*25cm; water depth 20cm. The playedback sound was a white noise file with continuous temporal pattern (200-4000 Hz). The results of the sound pressure gradient in the fish tank showed that in the side wall near the speaker location, there was a sharp sound pressure gradient. Moreover, near all the walls of the fish tank, despite moving away from the sound source, the walls of the fish tank played a role as a secondary source of sound and induced elevation of the sound pressure levels. Oscillation of sound levels and the lack of a clear gradient of sound in the longitudinal direction in the fish tank may be due to the presence of standing waves and related to the dimensions of the fish tank. It is essential to assess the acoustic field in any tank in which sound playbacks and bioacoustics are to be carried out.

Creators: name: Cella, Eleonora
Publisher: name: Sapienza Università Editrice

description: Carbapenems resistant Enterobacteriaceae infections are increasing worldwide representing an emerging public health problem. The application of phylogenetic and phylodynamic analyses to bacterial whole genome sequencing (WGS) data have become essential in epidemiological surveillance of MDR pathogens to discern outbreak from non-outbreak strains in both community and hospital settings.
In this study, K. pneumoniae strains circulating within different wards of university hospital were collected and WGS applied. Moreover a microbiological surveillance on duedonoscopes was performed to evaluate their reprocessing. The aim was to infer the origin and the spread of K. pneumoniae nosocomial strains and to clarify the epidemiological transmission as so as the eventual reservoir in the hospital setting supporting the epidemiological surveillance and infections control strategies.

description: We theoretically investigated phonon dispersion in AA-stacked, AB-stacked and twisted bilayer graphene with various rotation angles. The calculations were performed using the Born-von-Karman model for the intra-layer atomic interactions and the Lennard-Jones potential for the inter-layer interactions. It was found that the stacking order affects the out-of-plane acoustic phonon modes the most. The difference in the phonon densities of states in the twisted bilayer graphene and in AA- or AB-stacked bilayer graphene appears in the phonon frequencies range 90 - 110 1/cm. Twisting bilayer graphene leads to emergence of new phonon branches - termed entangled phonons - which originate from mixing of phonon modes from different high-symmetry directions in the Brillouin zone. The frequencies of the entangled phonon depend strongly on the rotation angle and can be used for non-contact identification of the twist angles in graphene samples. The obtained results and tabulated frequencies of phonons in twisted bilayer graphene are important for interpretation of experimental Raman data and determining thermal conductivity of these materials systems.

description: The strength and direction of migration of low mass embedded planets depends on the disk's thermodynamic state, where the internal dissipation is balanced by radiative transport, and the migration can be directed outwards, a process which extends the lifetime of growing embryos. Very important parameters determining the structure of disks, and hence the direction of migration, are the viscosity and the adiabatic index. In this paper we investigate the influence of different viscosity prescriptions (alpha-type and constant) and adiabatic indices on disk structures and how this affects the migration rate of planets embedded in such disks. We perform 3D numerical simulations of accretion disks with embedded planets. We use the explicit/implicit hydrodynamical code NIRVANA that includes full tensor viscosity and radiation transport in the flux-limited diffusion approximation, as well as a proper equation of state for molecular hydrogen. The migration of embedded 20Earthmass planets is studied. Low-viscosity disks have cooler temperatures and the migration rates of embedded planets tend toward the isothermal limit. In these disks, planets migrate inwards even in the fully radiative case. The effect of outward migration can only be sustained if the viscosity in the disk is large. Overall, the differences between the treatments for the equation of state seem to play a more important role in disks with higher viscosity. A change in the adiabatic index and in the viscosity changes the zero-torque radius that separates inward from outward migration. For larger viscosities, temperatures in the disk become higher and the zero-torque radius moves to larger radii, allowing outward migration of a 20 Earth-mass planet to persist over an extended radial range. In combination with large disk masses, this may allow for an extended period of the outward migration of growing protoplanetary cores.

description: We apply the Hamilton-Jacobi equation (HJE) formalism to solve the dynamics of the Chemical Master Equation (CME). We found exact analytical expressions (in large system-size limit) for the probability distribution, including explicit expression for the dynamics of variance of distribution. We also give the solution for some simple cases of the model with time-dependent rates. We derived the results of Van Kampen method from HJE approach using a special ansatz. Using the Van Kampen method, we give a system of ODE to define the variance in 2-d case. We performed numerics for the CME with stationary noise. We give analytical criteria for the disappearance of bi-stability in case of stationary noise in 1-d CME.

description: We study the dynamics of the interface between two immiscible fluids in contact with a chemically homogeneous moving solid plate. We consider the generic case of two fluids with any viscosity ratio and of a plate moving in either directions (pulled or pushed in the bath). The problem is studied by a combination of two models, namely an extension to finite viscosity ratio of the lubrication theory and a Lattice Boltzmann method. Both methods allow to resolve, in different ways, the viscous singularity at the triple contact between the two fluids and the wall. We find a good agreement between the two models particularly for small capillary numbers. When the solid plate moves fast enough, the entrainment of one fluid into the other one can occur. The extension of the lubrication model to the case of a non-zero air viscosity, as developed here, allows us to study the dependence of the critical capillary number for air entrainment on the other parameters in the problem (contact angle and viscosity ratio).

description: In the recent past, the evolution of stratospheric ozone (O3) was affected by both increasing ozone depleting substances (ODSs) and greenhouse gases (GHGs). The impact of the single forcings on O3 is well known. Interactions between the simultaneously increased GHG and ODS concentrations, however, can occur and lead to nonlinear O3 changes. In this study, we investigate if nonlinear processes have affected O3 changes between 1960 and 2000. This is done with an idealised set of time slice simulations with the chemistry-climate model EMAC. Due to nonlinearity the past ozone loss is diminished throughout the stratosphere, with a maximum reduction of 1.2 % at 3 hPa. The total ozone column loss between 1960 and 2000 that is mainly attributed to the ODS increase is mitigated in the extra-polar regions by up to 1.1 % due to nonlinear processes. A separation of the O3 changes into the contribution from chemistry and transport shows that nonlinear interactions occur in both. In the upper stratosphere a reduced efficiency of the ClOx-catalysed O3 loss chiefly causes the nonlinear O3 increase. An enhanced formation of halogen reservoir species through the reaction with methane (CH4) reduces the abundance of halogen radicals significantly. The temperature-induced deceleration of the O3 loss reaction rate in the Chapman cycle is reduced, which leads to a nonlinear O3 decrease and counteracts the increase due to ClOx. Nonlinear effects on the NOx abundance cause hemispheric asymmetric nonlinear changes of the O3 loss. Nonlinear changes in O3 transport occur in particular in the Southern Hemisphere (SH) during the months September to November. Here, the residual circulation is weakened in the lower stratosphere, which goes along with a reduced O3 transport from the tropics to high latitudes. Thus, O3 decreases in the SH polar region but increases in the SH midlatitudes. The existence of nonlinearities implies that future ozone change due to ODS decline slightly depends on the prevailing GHG concentrations. Therefore the future ozone evolution will not simply be a reversal of the past.
title: Modelling of an Intelligent Microgrid System in a Smart Grid Network
Creators: name: Mariam, Lubna
Publisher: name: Technological University of Dublin
Year: 2018

description: To achieve the goal of decarbonising the electric grid by 2050 and empowering energy citizen, this research focuses on the development of Microgrid (μGrid) systems in Irish environment. As part of the research work, an energy efficient and cost effective solution for μGrid, termed Community-μGrid (C-μGrid) is proposed. Here the users can modify their micro-Generation (μGen) converters to facilitate a single inverter in a C-μGrid structure. The new system could allow: (i) technological advantage of improved Power Quality (PQ); (ii) economic advantage of reduced cost of energy (COE) to achieve sustainability. Analysis of scenarios of C-μGrid (AC) systems is performed for a virtual community in Dublin, Ireland. It consists of (10 to 50) similar type of residential houses and assumes that each house has a wind-based μGen system. It is found that, compared to individual off-grid μGen systems, an off-grid C-μGrid can reduce upto 35% of energy storage capacity. Thus it helps to reduce the COE from €0.22/kWh to 0.16/kWh. In grid connected mode, it can sell excess energy to the grid and thus COE further decreases to €0.11/kWh. Thus a cost-effective C-μGrid is achieved.

The proposed system can advance its energy management efficiency through implementation of Demand Side Management (DSM) technique. For the test case, 50% of energy storage capacity could be avoided through DSM technique. It also helps to further decrease the COE by 25%. The C-μGrid system with storage is optimised by implementing the Economic Model Predictive Control (EMPC) approach operating at the pricing level. Emphasis is given to the operational constraints related to the battery lifetime, so that the maintenance and replacement cost would be reduced. This technique could help to improve the battery performance with optimised storage and also reduces the COE of the system by 25%.

description: This study addresses the challenge of quantifying the complex and non-linear correlations between the technical properties of ultra-high-Performance concrete (UHPC) and its mixture composition through conventional statistical methods. To tackle this, this study employs five advanced machine learning methods: Random Forest (RF), Long-Short-Term Memory, Convolutional Neural Network, K-Nearest Neighbor, and Adaboost. A dataset comprising 308 UHPC compressive strength tests with varying amounts of cement, silica fumes, superplasticizers, ground granulated blast furnace slag, fine aggregates, coarse aggregates, age, and temperature was used to train these models. The models’ performance was validated using statistical metrics, regression error characteristic curve, SHAP analysis, and uncertainty analysis. Among the models, the RF model achieved the highest prediction accuracy with an R2 of 0.9877 and an RMSE of 0.0323. This study also introduces an open-source graphical user interface based on the RF model, providing engineers with a practical tool for estimating the compressive strength of UHPC and facilitating mix proportioning decisions. This interface aims to bridge the gap between machine learning predictions and practical applications in UHPC mix design.

description: Random walks on multidimensional nonlinear landscapes are of interest in many areas of science and engineering. In particular, properties of adaptive trajectories on fitness landscapes determine population fates and thus play a central role in evolutionary theory. The topography of fitness landscapes and its effect on evolutionary dynamics have been extensively studied in the literature. We will survey the current research knowledge in this field, focusing on a recently developed systematic approach to characterizing path lengths, mean first-passage times, and other statistics of the path ensemble. This approach, based on general techniques from statistical physics, is applicable to landscapes of arbitrary complexity and structure. It is especially well-suited to quantifying the diversity of stochastic trajectories and repeatability of evolutionary events. We demonstrate this methodology using a biophysical model of protein evolution that describes how proteins maintain stability while evolving new functions.

multiband channel modelling

description: The present report introduces the measurement results and parameter estimation for multi-band channel modelling in Industry scenario. The measurements were conducted in a Bosch factory and in a laboratory at Fraunhofer facilities, both in Germany. After the measurements, the data needed to be analysed and prepared for the calibration of the channel modelling task presented in Deliverable D3.4. This deliverable presents validation research to enable new cross-frequency services for the industry environment but in the same way, these results are essential for development of new cross-frequency services in other areas such as V2V or Smart Home. The understanding of the different physical propagation properties of the frequency bands from Sub-6 GHz to THz and OWC enables the creation of a unique framework for further developments in 6G, which is currently unique in the world.
Innovations in machine learning: a case study of the Fabricius Workbench
Creators: name: Kelly, Bree
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis investigates how the open-source computer program called the Fabricius Workbench complements the process of translating Hieroglyphic Egyptian texts. The Workbench, developed by Google, Ubisoft, and Psycle Interactive, employs machine learning in an attempt to speed up translation, as has been successfully carried out for other - even ancient - languages. The Workbench utilises machine learning to identify images of Egyptian hieroglyphs. Users can edit a facsimile layer and reconstruct damaged sections of text. The program also suggests words to assist the user in formulating their translation. Workbench project files are stored in a format that is easily shared and edited. By employing eight volunteer Egyptologists of varying skill levels to produce a translation using the Workbench, this thesis evaluated whether there are elements of the program that demonstrate how digital tools might improve the translation process. After analysing the outcomes of the case study by considering the strengths, weaknesses, opportunities, and threats (SWOT) of the program, focusing on user experience, initial expectations of the Workbench had to be reconsidered. The program as it stands would require significant improvements to become a viable tool for Egyptologists. As such, focusing on the individual components of the Workbench would offer earlier rewards and develop a community of users who could demonstrate academic outcomes, thus encouraging further development. Therefore, the program either needs to split into its smaller components or pivot to a tool within a pedagogical program that would sustain the established userbase. Since the Workbench demonstrates that digital technology can be used to capture, manipulate, and analyse hieroglyphic information, it is suggested that students of Hieroglyphic Egyptian could be presented with activities and exercises that show them how to encode and mark up hieroglyphs in order to contribute to the amount of digital textual material of the Ancient Egyptian language available worldwide.
The existence of a canonical lifting of even Poisson Structures to the Algebra of Densities

Publisher: name: arXiv

Subjects: subject: Mathematical Physics (math-ph)

description: In this note we construct a canonical lifting of arbitrary Poisson structures on a manifold to its algbera of densities. Using this construction we proceed to classify all extensions of a fixed structure on the original manifold to its algebra of densities. The question is analogous to the problem studied by H.M.Khudaverdian and Th.Voronov for odd Poisson structures and differential operators. Although the questions are similar the results are distinctly marked, namely in the case of even Poisson structures there always exists a lift which is naturally defined. The proof of this result bears a remarkable resemblance to the construction of the Frolicher-Nijenhuis bracket.

description: We present the metallicity results from the ARGOS spectroscopic survey of the Galactic bulge. Our aim is to understand the formation of the Galactic bulge: did it form via mergers, as expected from Lambda CDM theory, or from disk instabilities, as suggested by its boxy/peanut shape, or both? We have obtained spectra for 28,000 stars at a spectral resolution of R = 11,000. From these spectra, we have determined stellar parameters and distances to an accuracy of < 1.5 kpc. The stars in the inner Galaxy span a large range in [Fe/H], -2.8 < [Fe/H] < +0.6. From the spatial distribution of the red clump stars as a function of [Fe/H] (Ness et al. 2012a), we propose that the stars with [Fe/H] > -0.5 are part of the boxy/peanut bar/bulge. We associate the lower metallicity stars ([Fe/H] < -0.5) with the thick disk, which may be puffed up in the inner region, and with the inner regions of the metal-weak thick disk and inner halo. For the bulge stars with [Fe/H] > -0.5, we find two discrete populations; (i) stars with [Fe/H] ~ -0.25 which provide a roughly constant fraction of the stars in the latitude interval b = -5 deg to -10 deg, and (ii) a kinematically colder, more metal-rich population with mean [Fe/H] ~ +0.15 which is more prominent closer to the plane. The changing ratio of these components with latitude appears as a vertical abundance gradient of the bulge. We attribute both of these bulge components to instability-driven bar/bulge formation from the thin disk. We do not exclude a weak underlying classical merger-generated bulge component, but see no obvious kinematic association of any of our bulge stars with such a classical bulge component. [abridged]

description: For cone-beam three-dimensional computed tomography (3D-CT) scanning system, voxel size is an important indicator to guarantee the accuracy of data analysis and feature measurement based on 3D-CT images. Meanwhile, the voxel size changes with the movement of the rotary table along X-ray direction. In order to realize the automatic calibration of the voxel size, a new easily-implemented method is proposed. According to this method, several projections of a spherical phantom are captured at different imaging positions and the corresponding voxel size values are calculated by non-linear least square fitting. Through these interpolation values, a linear equation is obtained, which reflects the relationship between the rotary table displacement distance from its nominal zero position and the voxel size. Finally, the linear equation is imported into the calibration module of the 3D-CT scanning system, and when the rotary table is moving along X-ray direction, the accurate value of the voxel size is dynamically exported. The experimental results prove that this method meets the requirements of the actual CT scanning system, and has virtues of easy implementation and high accuracy

description: Stars more massive than about 8 Msun end their lives as a Supernova (SN), an event of fundamental importance Universe-wide. Theoretically, these stars have been expected to be either at the red supergiant, blue supergiant, or Wolf-Rayet stage before the explosion. We performed coupled stellar evolution and atmospheric modeling of stars with initial masses between 20 Msun and 120 Msun. We found that the 20 Msun and 25 Msun rotating models, before exploding as SN, have spectra that do not resemble any of the aforementioned classes of massive stars. Rather, they have remarkable similarities with rare, unstable massive stars known as Luminous Blue Variables (LBV). While observations show that some SNe seem to have had LBVs as progenitors, no theoretical model had yet predicted that a star could explode at this stage. Our models provide theoretical support for relatively low-luminosity LBVs exploding as SN in the framework of single stellar evolution. This is a significant shift in paradigm, meaning that a fraction of LBVs could be the end stage of massive star evolution, rather than a transitory evolutionary phase. We suggest that type IIb SN could have LBV as progenitors, and a prime example could be SN 2008ax.

description: We are going to analyze through a first order perturbative formulation the local loss of symmetry when a source of electromagnetic and gravitational field interacts with an agent that perturbes the original geometry associated to the source. As the symmetry in Abelian or even non-Abelian field structures in four dimensional Lorentzian spacetimes is displayed through the existence of local planes of symmetry that we previously called blades one and two, the loss of symmetry will be manifested by the tilting of these planes under the influence of the external agent. In this strict sense the original local symmetry will be lost. But we will prove that the new blades at the same point will correspond after the tilting generated by perturbation to a new symmetry. The point of this note is to prove that the geometrical manifestation of local gauge symmetries is dynamic. The local original symmetries will be lost, nonetheless new symmetries will arise. There is a dynamic evolution of local symmetries.

description: We describe the motivation, field locations and stellar selection for the ARGOS spectroscopic survey of 28,000 stars in the bulge and inner disk of the Milky Way galaxy across latitudes of b = -5 deg to -10 deg. The primary goal of this survey is to constrain the formation processes of the bulge and establish whether it is predominantly a merger or instability remnant. From the spectra (R = 11,000), we have measured radial velocities and determined stellar parameters, including metallicities and [alpha/Fe] ratios. Distances were estimated from the derived stellar parameters and about 14,000 stars are red giants within 3.5 kpc of the Galactic centre. In this paper, we present the observations and analysis methods. Subsequent papers (III and IV) will discuss the stellar metallicity distribution and kinematics of the Galactic bulge and inner disk, and the implications for the formation of the bulge.

The Asia-born population and their descendants in Australia: exploring their heterogeneous labour market outcomes
Creators: name: De Alwis, Sheruni
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: In the decade leading up to 2016, most immigrants arriving in Australia came from Asia, mainly as skilled immigrants. Due to previously small population sizes, the existing literature of immigrant labour market outcomes tended to categorise the Asian population as a homogeneous group with immigrants from other non-English speaking backgrounds. This thesis aims to address a gap in knowledge of Asian intra- and inter-group diversity by delineating the Asian population by country of birth, religious affiliation and generational status. The thesis uses Australian census data from 2011 and 2016 and employs multivariate regression methods. First, this thesis applies a new extension of the realised matches method of measuring over-education to explore the significant differences in the likelihood and severity of an education-occupation mismatch among Asian birthplace groups. The results show that serious cases of over-education are significantly more likely among Asian immigrants—predominantly China-born and India-born—than among other immigrants. It then examines the employment likelihood, occupational status and earnings of the largest Asian birthplace groups and religious subgroups in Australia. The results highlight the critically important role of religion in explaining Asian immigrant labour market outcomes. A birthplace-religion interaction also highlights significant variation in the effects of religion across the Asian birthplace groups. Finally, this thesis explores the occupational status of 1.5 generation and 2nd-generation Asian immigrants in comparison with their 1st-generation counterparts. The results show greater intergenerational upward occupational mobility for all the selected Asian groups compared with immigrants from other countries. However, the extent of upward occupational mobility varies greatly between Asian birthplace groups. The findings of this thesis deepen the understanding of the heterogeneity in Asian immigrants’ labour market integration in Australia. The implications of the findings for immigrant selection, immigrant settlement programs and diversity management practices are also outlined.

description: In typical Dark Triad (DT) questionnaires, generic items oftentimes refer to “others” or “people” in general. Hence, respondents have to mentally aggregate their behavior across several kinds of “others” (e.g., work colleagues, family members, and friends). It remains unknown if individuals consider different kinds of interaction partners equally or if their self-reports contain “hidden” interaction partner-specific tendencies. To shed light on this issue, we assessed generic and contextualized DT items (referring to family, friends, work, and strangers; N = 814 from the general population). The correlated trait-correlated (method − 1) model was used to investigate preregistered research questions. On average, generic DT items showed the strongest association with work-contextualized DT items and the weakest association with family-contextualized DT items. However, the associations varied considerably across DT items and traits. In sum, our results suggest that hidden framings exist in some DT items, which may impact their ability to predict relevant criteria due to contextual (a)symmetries. The generalizability of the findings to other DT instruments, items, and participant groups should be examined in future research.

description: We discuss a class of diffusion-type partial differential equations on a bounded interval and discuss the possibility of replacing the boundary conditions by certain linear conditions on the moments of order 0 (the total mass) and of another arbitrarily chosen order n. Each choice of n induces the addition of a certain potential in the equation, the case of zero potential arising exactly in the special case of n=1 corresponding to a condition on the barycenter. In the linear case we exploit smoothing properties and perturbation theory of analytic semigroups to obtain well-posedness for the classical heat equation (with said conditions on the moments). Long time behavior is studied for both the linear heat equation with potential and certain nonlinear equations of porous medium or fast diffusion type. In particular, we prove polynomial decay in the porous medium range and exponential decay in the fast diffusion range, respectively.

description: We develop a simplified light source at 461 nm for laser cooling of Sr without frequency-doubling crystals but with blue laser diodes. An anti-reflection coated blue laser diode in an external cavity (Littrow) configuration provides an output power of 40 mW at 461 nm. Another blue laser diode is used to amplify the laser power up to 110 mW by injection locking. For frequency stabilization, we demonstrate modulation-free polarization spectroscopy of Sr in a hollow cathode lamp. The simplification of the laser system achieved in this work is of great importance for the construction of transportable optical lattice clocks.
