description: High-precision mass measurements of exotic $^{95-97}$Ag isotopes close to the $N = Z$ line have been conducted with the JYFLTRAP double Penning trap mass spectrometer, with the silver ions produced using the recently commissioned inductively-heated hot cavity catcher laser ion source at the Ion Guide Isotope Separator On-Line facility. The atomic mass of $^{95}$Ag was directly determined for the first time. In addition, the atomic masses of $β$-decaying 2$^+$ and 8$^+$ states in $^{96}$Ag have been identified and measured for the first time, and the precision of the $^{97}$Ag mass has been improved. The newly measured masses, with a precision of $\approx$ 1 keV/c$^2$, have been used to investigate the $N =$ 50 neutron shell closure confirming it to be robust. Empirical shell-gap and pairing energies determined with the new ground-state mass data are compared with the state-of-the-art \textit{ab initio} calculations with various chiral effective field theory Hamiltonians. The precise determination of the excitation energy of the $^{96m}$Ag isomer in particular serves as a benchmark for \textit{ab initio} predictions of nuclear properties beyond the ground state, specifically for odd-odd nuclei situated in proximity to the proton dripline below $^{100}$Sn. In addition, density functional theory (DFT) calculations and configuration-interaction shell-model (CISM) calculations are compared with the experimental results. All theoretical approaches face challenges to reproduce the trend of nuclear ground-state properties in the silver isotopic chain across the $N =$50 neutron shell and toward the proton drip-line.

description: Bias or spurious correlations in image backgrounds can impact neural networks, causing shortcut learning (Clever Hans Effect) and hampering generalization to real-world data. ISNet, a recently introduced architecture, proposed the optimization of Layer-Wise Relevance Propagation (LRP, an explanation technique) heatmaps, to mitigate the influence of backgrounds on deep classifiers. However, ISNet's training time scales linearly with the number of classes in an application. Here, we propose reformulated architectures whose training time becomes independent from this number. Additionally, we introduce a concise and model-agnostic LRP implementation. We challenge the proposed architectures using synthetic background bias, and COVID-19 detection in chest X-rays, an application that commonly presents background bias. The networks hindered background attention and shortcut learning, surpassing multiple state-of-the-art models on out-of-distribution test datasets. Representing a potentially massive training speed improvement over ISNet, the proposed architectures introduce LRP optimization into a gamut of applications that the original model cannot feasibly handle.

description: Under fatigue loading, the stiffness decrease in short-fiber reinforced polymers reflects the gradual degradation of the material. Thus, both measuring and modeling this stiffness is critical to investigate and understand the entire fatigue process. Besides evolving damage, viscoelastic effects within the polymer influence the measured dynamic stiffness. In this paper, we study the influence of a linear viscoelastic material model for the matrix on the obtained dynamic stiffness and extend an elastic multiscale fatigue-damage model to viscoelasticity. Our contribution is two-fold. First, we revisit the complex-valued elastic models known in the literature to predict the asymptotic periodic orbit of a viscoelastic material. For small phase shifts in an isotropic linear viscoelastic material, we show through numerical experiments that a real-valued computation of an “elastic” material is sufficient to approximate the dynamic stiffness of a microstructure with a generalized Maxwell material and equal Poisson’s ratios in every element as matrix, reinforced by elastic inclusions. This makes standard solvers applicable to fiber-reinforced thermoplastics. Secondly, we propose a viscoelastic fatigue-damage model for the thermoplastic matrix based on decoupling of the time scales where viscoelastic and fatigue-damage effects manifest. We demonstrate the capability of the multiscale model to predict the dynamic stiffness evolution under fatigue loading of short-fiber reinforced polybutylene terephthalate (PBT) by a validation with experimental results.

description: Elucidating the reasoning process with structured explanations from question to answer is crucial, as it significantly enhances the interpretability, traceability, and trustworthiness of question-answering (QA) systems. However, structured explanations demand models to perform intricately structured reasoning, which poses great challenges. Most existing methods focus on single-step reasoning through supervised learning, ignoring logical dependencies between steps. Moreover, existing reinforcement learning (RL) based methods overlook the structured relationships, underutilizing the potential of RL in structured reasoning. In this paper, we propose SEER, a novel method that maximizes a structure-based return to facilitate structured reasoning and explanation. Our proposed structure-based return precisely describes the hierarchical and branching structure inherent in structured reasoning, effectively capturing the intricate relationships between different reasoning steps. In addition, we introduce a fine-grained reward function to meticulously delineate diverse reasoning steps. Extensive experiments show that SEER significantly outperforms state-of-the-art methods, achieving an absolute improvement of 6.9% over RL-based methods on EntailmentBank, a 4.4% average improvement on STREET benchmark, and exhibiting outstanding efficiency and cross-dataset generalization performance.

description: The direct detection of dark matter constituents, in particular the weakly interacting massive particles (WIMPs), is central to particle physics and cosmology. In this paper we study WIMP induced transitions from isomeric nuclear states for two possible isomeric candidates: $\rm^{180}Ta$ and $\rm^{166}Ho$. The experimental setup, which can measure the possible decay of $\rm^{180}Ta$ induced by WIMPs, was proposed. The corresponding estimates of the half-life of $\rm^{180}Ta$ are given in the sense that the WIMP-nucleon interaction can be interpreted as ordinary radioactive decay.

description: We extend topologically massive electrodynamics, both by adding a higher derivative action to cast the entire three-term model in Chern-Simons (CS) form, and by embedding it in an AdS background. It can then be written as the sum of two CS terms, one of which vanishes at the "chiral" point, in analogy with its gravitational topologically massive counterpart. Separately we treat pure CS electrodynamics plus Einstein gravity interacting with point sources. The gravity/vector field equations decouple; their solutions are the familiar exterior "conical" metric and vector potentials.

description: Bits and Pieces. Two New Finds from Norway and an Update on the Interpretation of Alsengems
Two new fragmentary Alsengems are presented from the old town of Oslo, the first one found in a grave from the 13th century, the other in the floor of a late 12th century building. Alsengems have long been interpreted as pilgrim badges of the Three Kings in Cologne. This hypothesis of M. Schulze-Dörrlamm is no longer tenable.
Following up on M. Roslund and A. Håkansson, Alsengems are to be regarded as group markers worn by Frisian traders. Alsengems were most probably produced in Friesland. It is put forward that the merchandise of the Frisian traders may have been grain, especially oats, meant for the emergent brewing industry.

description: Understanding the late-time acceleration of the universe and its subtleties is one of the biggest mysteries in cosmology. A lot of different approaches have been put forward to deal with this, ranging from the conventional cosmological constant to various models of dark energy and beyond. Recently one very interesting approach to explaining the late time acceleration has been put forward, where the the expansion of the universe is driven by mergers with other "baby" universes and has been shown to be quite viable as well from the point of view of recent observational data. So in this work we examine the possibility of various rip scenarios and other future cosmological singularities in such "multiversal" scenario, probing such singularities for the first time in a multi universe scenario. We examine two models of such a baby universe merging cosmology, and show that remarkably no rip scenario or future cosmological singularity is possible in such models.

Radiative and Semileptonic B Decays Involving Higher K-Resonances in the Final States

description: We study the radiative and semileptonic B decays involving a spin-$J$ resonant $K_J^{(*)}$ with parity $(-1)^J$ for $K_J^*$ and $(-1)^{J+1}$ for $K_J$ in the final state. Using the large energy effective theory (LEET) techniques, we formulate $B \to K_J^{(*)}$ transition form factors in the large recoil region in terms of two independent LEET functions $ζ_\perp^{K_J^{(*)}}$ and $ζ_\parallel^{K_J^{(*)}}$, the values of which at zero momentum transfer are estimated in the BSW model. According to the QCD counting rules, $ζ_{\perp,\parallel}^{K_J^{(*)}}$ exhibit a dipole dependence in $q^2$. We predict the decay rates for $B \to K_J^{(*)} γ$, $B \to K_J^{(*)} \ell^+ \ell^-$ and $B \to K_J^{(*)}ν\barν$. The branching fractions for these decays with higher $K$-resonances in the final state are suppressed due to the smaller phase spaces and the smaller values of $ζ^{K_J^{(*)}}_{\perp,\parallel}$. Furthermore, if the spin of $K_J^{(*)}$ becomes larger, the branching fractions will be further suppressed due to the smaller Clebsch-Gordan coefficients defined by the polarization tensors of the $K_J^{(*)}$. We also calculate the forward backward asymmetry of the $B \to K_J^{(*)} \ell^+ \ell^-$ decay, for which the zero is highly insensitive to the $K$-resonances in the LEET parametrization.

description: We introduce the task of shadow process simulation, where the goal is to simulate the estimation of the expectation values of arbitrary quantum observables at the output of a target physical process. When the sender and receiver share random bits or other no-signaling resources, we show that the performance of shadow process simulation exceeds that of conventional process simulation protocols in a variety of scenarios including communication, noise simulation, and data compression. Remarkably, we find that there exist scenarios where shadow simulation provides increased statistical accuracy without any increase in the number of required samples.

description: The covariance matrix adaptation evolution strategy (CMA-ES) is one of the most successful methods for solving continuous black-box optimization problems. A practically useful aspect of the CMA-ES is that it can be used without hyperparameter tuning. However, the hyperparameter settings still have a considerable impact on performance, especially for difficult tasks, such as solving multimodal or noisy problems. This study comprehensively explores the impact of learning rate on the CMA-ES performance and demonstrates the necessity of a small learning rate by considering ordinary differential equations. Thereafter, it discusses the setting of an ideal learning rate. Based on these discussions, we develop a novel learning rate adaptation mechanism for the CMA-ES that maintains a constant signal-to-noise ratio. Additionally, we investigate the behavior of the CMA-ES with the proposed learning rate adaptation mechanism through numerical experiments, and compare the results with those obtained for the CMA-ES with a fixed learning rate and with population size adaptation. The results show that the CMA-ES with the proposed learning rate adaptation works well for multimodal and/or noisy problems without extremely expensive learning rate tuning.

Fano-Kondo effect in side-coupled double quantum dots at finite temperatures and the importance of the two-stage Kondo screening
Creators: name: Zitko, Rok
Publisher: name: arXiv
Year: 2010
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We study the zero-bias conductance through the system of two quantum dots, one of which is embedded directly between the source and drain electrodes, while the second dot is side-coupled to the first one through a tunneling junction. Modeling the system using the two-impurity Anderson model, we compute the temperature-dependence of the conductance in various parameter regimes using the numerical renormalization group. We consider the non-interacting case, where we study the extent of the departure from the conventional Fano resonance line shape at finite temperatures, and the case where the embedded and/or the side-coupled quantum dot is interacting, where we study the consequences of the coexistence of the Kondo and Fano effects. If the side-coupled dot is very weakly interacting, the occupancy changes by two when the on-site energy crosses the Fermi level and a Fano-resonance-like shape is observed. If the interaction on the side-coupled dot is sizeable, the occupancy changes only by one and a very different line-shape results, which is strongly and characteristically temperature dependent. These results suggest an intriguing alternative interpretation of the recent experimental results study of the transport properties of the side-coupled double quantum dot [Sasaki et al., Phys. Rev. Lett. 103, 266806 (2009)]: the observed Fano-like conductance anti-resonance may, in fact, result from the two-stage Kondo effect in the regime where the experimental temperature is between the higher and the lower Kondo temperature.

Early identification of developmental impairments in infants from birth to nine months of age / |c by M. Grace Doherty
Creators: name: Doherty, M. Grace
Publisher: name: University of British Columbia
Year: 2010

description: Early recognition of real or potential developmental impairments in infants is an important public health role. Community health nurses have initial access to the infant population by the mandated newborn visit and the necessary skills and tools to assess infants for developmental impairments. This experimental study was undertaken to determine the effectiveness of scheduled nursing assessments of growth, development, vision, hearing and nutrition from birth to nine months of age. A secondary purpose was to determine the predictive validity of currently used pregnancy and infant profiles for subsequent developmental impairment. The null hypotheses tested were: I. That the scheduled, community health nursing assessments between birth and nine months of age will not detect any developmental impairments which have not already been detected by existing health services. II. That there is no significant difference in the number of developmental impairments detected at nine months of age, between a group of infants screened by the proposed schedule of assessments and a group not so screened. III. That there is no significant difference in the number of children exhibiting developmental impairments by nine months of age, between a group of "at risk" and a group of not "at risk" infants, using the criteria from the Vancouver Health Department's Pregnancy Profile and Infant Profile At Risk Criteria. One hundred infants from one health unit area were studied, alternately assigned to an experimental and a control group. The experimental group received three visits in addition to the newborn visit, at 1 month, 3 months, and 6 months, for various combinations of five types of assessments. The control group received only the usual newborn visit, but no control was used to prevent access to any other health services during the study period. Pregnancy and infant profiles were completed for the subjects in both groups at the initial visit. 9 month assessments of growth, development, vision, hearing and nutrition were completed for both groups. The data were subjected to descriptive analysis and statistical analysis by Fisher's exact test of probability, using 2x2 contingency tables. The findings supported scheduled community health nursing assessments of infants from birth to nine months of age. The pregnancy and infant profiles were found to be sensitive but not specific tools for prediction of subsequent developmental impairment. The three null hypotheses were rejected.

The Language of Globalization in Contemporary Irish Poetry

Publisher: name: Biblioteca di Studi di Filologia Moderna: Series, Journals and Workshop
Year: 2014

description: This essay considers how contemporary Irish poets have responded to the changing socio-economic realities of Irish life since 1990. Through an examination of themes of work, consumerism, the encroachment of cyber-space and changing urban lifestyles, the essay demonstrates how Irish poets have risen to the challenge of finding a language to capture what Zygmunt Bauman characterizes as ‘liquid modernity’. A range of poets are considered, including the late Dennis O’Driscoll, Rita Ann Higgins, Peter Sirr as well as Billy Ramsell, Kevin Higgins and Iggy McGovern. These poets’ musings provide excellent examples of how the poet can turn the language of globalization into a critique of globalization’s economic hegemony.

description: Finite-time quantum heat engines are of practical relevance as they can generate finite-power, distinguishing them from ideal quasistatic engines typically used for theoretical purposes. However, these engines encounter energy losses due to quantum friction, which is particularly pronounced in many-body systems with non-trivial coherences in their density operator. Strategies such as shortcuts to adiabaticity and fast routes to thermalization have been developed although the associated cost requirements remain uncertain. In this study, we theoretically investigate the finite-time operation of a trapped-atom Otto engine with light-induced dipole-dipole interactions and projection measurements in one of the isochoric processes. The investigation reveals that appropriate control of dipole-dipole interactions of the working medium prompts engine operation upon interacting with the hot reservoir, while projection measurements and adjustment of the unitary driving protocols effectively reduce quantum friction to enhance finite-time engine performance compared to non-interacting and quasi-static counterparts. This setup presents a compelling avenue for further investigation of finite-time many-body quantum heat engines and provides an opportunity to explore the full potential of photon-mediated dipole-dipole interactions in their operations.

description: We investigate thermodynamical properties of quantum electrodynamics in 1+1 dimensions. Discrete light cone quantization is used to compute the partition function of the canonical ensemble and the thermodynamical potential. The potential is evaluated for different system sizes and coupling strengths. We perform the continuum limit and the thermodynamical limit and present basic thermodynamical quantities as a function of temperature for the interacting system. A more accurate estimation of low lying bound state masses at non-perturbative coupling strength are determined due to the higher harmonic resolution.

Subjects: Uncategorized

description: The main object of this thesis is the design and manufacturing of a mechanical setup to drive multi-directionally-polarized shear wave motion for the purpose of dynamic elastography in a tensile pre-stressed anisotropic biological sample in an Ultra-High Field MRI system. The main requirements for this task are the structural stability of the system at high frequencies, the nonmagnetic materials needed for the manufacturing (since the magnetic field applied is in the order of magnitude of 10 Tesla and magnetic materials pose both a danger and will distort the acquired image), and the connectivity between the actuators and the wave generator to monitor and control the excitation. Once the setup is created, the testing is performed and from the results of the same, the imagining and evaluation steps of the iterative design process are repeated.\\ After an initial analysis of the different Elastography techniques, the focus is set to the Magnetic Resonance Imaging one. The main functioning and hardware requirements are explained, and an overview of the current equipment is provided. Afterward, the design of the setup itself is presented in detail with particular attention to the matching between all the components and the materials adopted to manufacture them. Finally, the testing with different experimental methods is conducted, and the results are discussed and compared with the expected theoretical ones. From this comparison, a conclusion on the validity of the experiments is proposed and some future developments are suggested to continue the work most effectively and efficiently.

description: In high energy proton-nucleus collisions, the gluon saturation effects from the nucleus are fully incorporated into the light-like Wilson lines. The gluon saturation effects from the proton, which are anticipated to be important either in the extreme high energy limit or towards the dense-dense (nucleus-nucleus) collision regimes, have been studied perturbatively within the Color Glass Condensate effective theory in previous papers of this series. A configuration-by-configuration expression for the single inclusive semi-hard gluon production including the first saturation correction was obtained. In this paper, we perform ensemble averaging in the McLerran-Venugopalan model and the Dipole Approximation. We find that, in the saturation correction, the effects of the initial state interactions are negligible while the final state interactions play most important role and give a positive-valued contribution to the semi-hard gluon spectrum. Furthermore, we show that the single gluon spectrum scales approximately $1/k_{\perp}^{4}$ at small $k_{\perp}$, suggesting that a resummation of higher order saturation corrections is required to regulate the infrared region of the gluon spectrum.

The paper deals with bracelets with splayed ends and decorated appliqués from the second half of the Avar period (second half of the 7th and 8th c. AD). This type of jewellery was uncommon in the Avar Kaghanate, most of them being found in the western part of the Carpathian Basin. Six types can be distinguished based on the ornamentation of the terminals. The earliest one with beaded trim and ribs is typical in the Vienna Basin and the Balaton region. Such bracelets are known from the Emilia Romagna, South Tyrolia and Styria. Most likely, the earliest specimens originated from Northern Italy and reached the Avars via the Alps in the last quarter of the 7th century. The other ornamental variations could be the results of internal developments. This kind of jewellery remained in fashion until the second half of the 8th century. The Lombardic-Avar contacts were examined mostly in the context of the Early Avar period. However, the bracelets with splayed ends and decorated appliqués serve as good evidence for the south-western connections of the Avars after the second half of the 7th century.

description: We evaluate the baryon number abundance based on the charge transport scenario of top quarks in the CP-violating two Higgs doublet model, in which Yukawa interactions are aligned to avoid dangerous flavor changing neutral currents, and coupling constants of the lightest Higgs boson with the mass $125~\mathrm{GeV}$ coincide with those in the standard model at tree level to satisfy the current LHC data. In this model, the severe constraint from the electric dipole moment of electrons, which are normally difficult to be satisfied, can be avoided by destructive interferences between CP-violating phases in Yukawa interactions and scalar couplings in the Higgs potential. Viable benchmark scenarios are proposed under the current available data and basic theoretical bounds. We find that the observed baryon number can be reproduced in this model, where masses of additional Higgs bosons are typically $300$--$400~\mathrm{GeV}$. Furthermore, it is found that the triple Higgs boson coupling is predicted to be $35$--$55~\%$ larger than the standard model value.

description: We delineate a general theoretical framework to determine the substrate-regulated graphene morphology through energy minimization. We then apply such a framework to study the graphene morphology on a substrate with periodic surface grooves. Depending on the substrate surface roughness and the graphene-substrate interfacial bonding energy, the equilibrium morphology of graphene ranges from 1) closely conforming to the substrate, to 2) remaining flat on the substrate. Interestingly, in certain cases, the graphene morphology snaps between the above two limiting states. Our quantitative results envision a promising strategy to precisely control the graphene morphology over large areas. The rich features of the substrate-regulated graphene morphology (e.g., the snap-through instability) can potentially lead to new design concepts of functional graphene device components.

description: CIL XIII 7290: ein victimarius legionis XXII aus Mainz-Kastel?
J. Huttich, ein aus Hessen stammender Humanist des frühen 16. Jahrhunderts, hat in seiner 1520 erschienenen Collectanea antiquitatum zahlreiche römische Denkmäler aus Mainz und der näheren Umgebung überliefert, die heute leider verschollen sind. Eines dieser Denkmäler, der in Mainz-Kastel gefundene Grabstein CIL XIII 7290, ist im Verlaufe der Zeit ganz unterschiedlich und zum Teil auch fehlerhaft kopiert worden. Besonders interessant sind dabei die unterschiedlichen Auflösungsvorschläge, die sich auf die militärische Funktion des Stifters beziehen, wobei nicht nur die kritische Auseinandersetzung mit der Überlieferungsgeschichte, sondern auch die zur Verfügung stehende Quellenlage die Möglichkeit in Erwägung ziehen lässt, den Dedikanten als victimarius legionis XXII bzw. victimarius legati legionis XXII zu identifizieren.

description: We consider the problem important for the condensed matter physics, superconductivity physics, and electrodynamics of continuous media - the problem of the matter dielectric permittivity possible values spectrum definition. Two ways of the dielectric permittivity values spectrum identification are analyzed. The proposed technique allows the author to complete the universal criterion of stability identified by D. A. Kirzhnits for a system of charged particles by the criterion of stability for a superconducting system of charged particles.

description: Der Main als militärischer Nachschubweg in römischer Zeit. Neue archäologische und geoarchäologische Untersuchungen
Die Flüsse Lahn, Main und Neckar sind die größten Flüsse der römischen Provinz Obergermanien, die den Rhein mit den östlichen Teilen der Provinz verbinden. Der Main ist derjenige von den drei Flüssen, der außerhalb des Mittelgebirges den längsten Lauf durch flaches Gelände hat. Der Fluss und sein Fließgewässernetz spielen eine zentrale Rolle für die Versorgung des Militärs im nördlichen Grenzabschnitt der Provinz. Zugleich diente er dem Transport von Rohstoffen von der Grenze ins Hinterland. In den letzten Jahren wurden sowohl archäologische als auch geoarchäologische Untersuchungen entlang des Flusses durchgeführt, die dieses Bild des genutzten und kontrollierten Wasserlaufs ergänzen und erweitern. Dies gibt Aufschluss über die unterschiedliche Nutzung des Flusses vom 1. bis zum 4. Jahrhundert n. Chr.

description: The Early Iron Age Hoard from Jodłowno (Pow. Gdański), Northern Poland. Technological Study of the Metal Raw Materials
This article deals with archaeological objects from the Jodłowno deposit in northern Poland. They were discovered using a metal detector. Some of the artifacts were left in situ; therefore, the arrangement of most objects is known. The assemblage dates to the Early Iron Age, probably Ha D (ca. 650/600–500/450 BC). The largest part of the inventory comprises the bar / ingot fragments. Each of the 49 ingots has been tested for its chemical composition. Four groups of raw materials were distinguished, whereby copper with a large amount of impurities was the largest. Lead was also an important addition. The results obtained enrich our knowledge of raw materials in northern Poland, Pomerania, Wielkopolska and Silesia in such categories of objects as ingots, hollow ankle rings and bow-shaped necklaces.

description: A Bronze Age Sauna in Nijmegen (Prov. Gelderland / NL): an Exceptional Site in Mainland Europe
This article presents a Bronze Age site in the Netherlands similar to the burnt mounds of the British Isles. Burnt mounds are, however, very exceptional on the European mainland, especially in combination with deep water pits. The site found in Nijmegen, dating from around the 16th century BC, seems to have comprised at least one sweat lodge and two plunge pools in an oak-dominated wood. Stones, but above all clay balls were used as sources of heat. Some votive deposits found in and near the adjacent residual channel emphasise the site’s ritual character. The long period of use combined with the absence of counterparts in the wider area raises the question whether the site’s users may have been migrants from across the North Sea.

description: Dental implant therapy is widely used to rehabilitate edentulous patients to overcome the limitations of conventional dentures. Treatment includes implant-retained overdentures and fixed complete dentures fabricated with polymethylmethacrylate (PMMA). Previous studies have shown that titanium dioxide (TiO2) coating on PMMA via Atomic Layer Deposition (ALD) has improved surface properties. However, the effect of this TiO2 coating on color is unknown. The goals of this study are to: (1) determine the color difference between PMMA before and after TiO2 coating; and (2) evaluate the color perceptibility and acceptability of PMMA with TiO2 coating. 45 PMMA 10x10x2 mm specimens were fabricated using light, original and dark pink Lucitone 199 according to manufacturer’s protocol. 10 specimens from each group underwent deposition of TiO2 coating using ALD. All specimens were measured with a spectroradiometer (PR 650; PhotoResearch Inc) before and after coating. Color difference (ΔE) before and after coating was calculated with Commission Internationale d’Eclairage formula 2000. Data were analyzed using ANOVA to compare the differences among the 3 groups (α<0.05). In each group, the recorded ΔE was compared to the perceptibility (ΔE = 1.71) and acceptability threshold (ΔE = 4.00) of PMMA by using independent t-tests (α<0.05). A clinical survey used to examine perception and acceptability of PMMA samples with and without TiO2 coating was conducted on 24 patients and 10 prosthodontists. Color change was observed after the deposition of TiO2 coating on all groups, light (ΔE =3.2 ± 0.8), original (ΔE =3.1 ± 0.7) and dark pink (ΔE =3.3 ± 1.2). The original samples had the least color change. There was no statistical significant difference among 3 groups (p=0.845). The ΔE of light (p<0.001), original (p<0.001), and dark pink (p=0.002) acrylic was significantly higher when compared to the established perceptibility threshold. However, this ΔE was significantly lower compared to the established acceptability threshold for light (p=0.01) and original (p=0.004) specimens. The clinical survey is consistent with the in vitro study as it demonstrated that generally a color difference was perceived but was clinically acceptable. This novel TiO2 coating via ALD on PMMA resulted in perceptible color changes, but color changes were generally still clinically acceptable.

description: Sollte auch der Bautypus Geleen in der Ursprungsregion der Bandkeramik entstanden sein? Erste und älteste Nachweise dieser Hausform aus Schwechat bei Wien
Im Spätherbst 2020 kamen bei einer Rettungsgrabung vor Errichtung der Park & Ride-Anlage für den Bahnhof Schwechat erstmals in Österreich zwei Gebäude des Typus Geleen zu Tage. Diese Hausgrundrisse werden hier zusammen mit datierendem Fundmaterial und einer kleinen Serie von fünf Radiokarbondaten präsentiert. Auf Basis der Keramik aus den begleitenden Längsgruben sind beide Häuser in die Spätphase der älteren Linearbandkeramik (Phase I b) zu datieren. Die 14C-Daten sind sehr homogen und weisen auf eine Zeitspanne von 5299–5209 cal. BC. – Bis jetzt sind 103 Hausgrundrisse mit Y-Konstruktion von 40 Fundplätzen bekannt, aber nur von sehr wenigen aus dem Rheinland und den Niederlanden liegen absolute Daten vor. Die neuen Daten aus Schwechat sind zwar deutlich älter, aber die zeitliche Distanz ist nicht sehr groß. Aus diesem Grunde kommt Schwechat wohl nicht als Ursprungsort dieses Konstruktionsprinzips in Frage, wohl aber die nähere Umgebung im östlichen Mitteleuropa. Derzeit gibt es allerdings in dieser Region keine weiteren Nachweise dieses Haustyps, was durch den Forschungsstand bedingt sein kann.
