description: The observational basis of quantum theory in accelerated systems is studied. The extension of Lorentz invariance to accelerated systems via the hypothesis of locality is discussed and the limitations of this hypothesis are pointed out. The nonlocal theory of accelerated observers is briefly described. Moreover, the main observational aspects of Dirac's equation in noninertial frames of reference are presented. The Galilean invariance of nonrelativistic quantum mechanics and the mass superselection rule are examined in the light of the invariance of physical laws under inhomogeneous Lorentz transformations.

Productivity Analysis

description: This study contributes to the agricultural productivity literature in developing countries and Nigeria especially by quantifying the level of efficiency for sample of rice farmers from North Central Zone of Nigeria. A stochastic efficiency decomposition frontier analysis was used to derive technical efficiency measures separately for rice under two production systems (upland and lowland systems). Average economic efficiency of 51.9 % and 55.4 % found for up land and lowland rice farmers respectively suggests that there is room for productivity gain for farms in the sample through better use of available resources given the state of technology. Gains in productivity growth have become increasingly important to Nigerians as demand for rice continue to increase due to population increase. Although, all the socio-economic variables tested against efficiency were significant at one level or the other there was no clear strategy of improving the relationship between them. One possible explanation for this finding is the existence of stage of developing threshold below which there is no consistent relationship between socioeconomic variables and productivity. The results suggest that rice farmers can still improve to reach such threshold in Nigeria. Hence, adoption of improved rice varieties, improvements in educational levels would be needed to go beyond this threshold before additional investments in human capital and other related factors.

description: A diamond anvil cell (DAC) which can generate extremely high pressure of multi-megabar is promising tool to develop a further physics such a high-transition temperature superconductivity. However, electrical transport measurements, which is one of the most important properties of such functional materials, using the DAC is quite difficult because the sample space is very small and a deformation of electrodes under extreme condition. In this study, we fabricated a boron-doped diamond micro-electrode and an undoped diamond insulation on a beveled culet surface of the diamond anvil. By using the developed DAC, we demonstrated the electrical transport measurements for sulfur hydride H$_2$S which known as a pressure-induced high-transition temperature superconducting H$_3$S at high pressure. The measurements were successfully conducted under high pressure up to 192 GPa, and then a multi-step superconducting transition composed from pure sulfur and some kinds of surfer hydrides, which is possible HS$_2$, was observed with zero resistance.

description: The production of lepton pairs in the Higgs boson decay $h \to \ell^+ \ell^- γ$ is studied. The emphasis is put on the structure of the Higgs boson interaction with the fermions. This interaction is chosen as a mixture of the scalar and pseudo-scalar couplings, and, in addition, it is supposed to be non-Hermitian. We study prediction of this model for the observables in the $h \to \ell^+ \ell^- γ$ decay for the $e^+ e^-$, $μ^+ μ^-$ and $τ^+ τ^-$ pairs. The differential decay width and lepton forward-backward asymmetry are calculated as functions of the dilepton invariant mass for several sets of $h f \bar{f}$ coupling constants. The influence of non-Hermitian $h f \bar{f}$ interaction on the forward-backward asymmetry is studied, and large influence of a possible non-Hermiticity of the Higgs interaction with the top quarks on forward-backward asymmetry for $e^+ e^-$ and $μ^+ μ^-$ pairs is stressed.

description: The present study investigates the analysis of poverty persistence of Chinese farm households in the well-off Zhejiang province in the southeast. We firstly apply an ordered probit model examining household, farm, and regional characteristics affecting the probability that households are chronically poor. In addition, we apply a hazard approach to identify the risk of falling into and climbing out of poverty. Results indicate that there are increasing chances to climb out of poverty over time, and that the risk of falling into poverty seems to decrease after the household spent some time outside poverty.

description: The research objective is to shed light on the structural adjustment process of farming enterprises in Switzerland. To this end, an analytical tool is developed which allows us to identify the most important influencing factors and to estimate in advance their effects on the structural adjustment process. The resulting structures will be compared with the relevant goals of the (agricultural) policy in order to draw conclusions about the effectiveness of the adjustment process. Using scenario techniques combined with an agent-based simulation, the influencing factors are varied to investigate alternative options like cooperation and collaboration strategies for improving the effectiveness with respect to the social, ecological and economic goals.

description: Protein interactions are important in a broad range of biological processes. Traditionally, computational methods have been developed to automatically predict protein interface from hand-crafted features. Recent approaches employ deep neural networks and predict the interaction of each amino acid pair independently. However, these methods do not incorporate the important sequential information from amino acid chains and the high-order pairwise interactions. Intuitively, the prediction of an amino acid pair should depend on both their features and the information of other amino acid pairs. In this work, we propose to formulate the protein interface prediction as a 2D dense prediction problem. In addition, we propose a novel deep model to incorporate the sequential information and high-order pairwise interactions to perform interface predictions. We represent proteins as graphs and employ graph neural networks to learn node features. Then we propose the sequential modeling method to incorporate the sequential information and reorder the feature matrix. Next, we incorporate high-order pairwise interactions to generate a 3D tensor containing different pairwise interactions. Finally, we employ convolutional neural networks to perform 2D dense predictions. Experimental results on multiple benchmarks demonstrate that our proposed method can consistently improve the protein interface prediction performance.

description: Based on the model of consumers' variety-seeking behavior introduced by Anderson et al. (1992), this paper derives a hedonic price function for a households' consumption bundle. The price a consumer pays for her consumption bundle reflects the values of the underlying attributes of goods purchased but also accounts for any preference for variety that she might have. The empirical analysis is conducted for 3,240 German households and their expenditure on 182 different soft drinks over a six-month period. We find that consumers have a preference for variety in food consumption, ceteris paribus. Furthermore, the per-unit price is found to be significantly larger for higher income households, as well as households where the principal wage earner has a high level of education. Larger households tend to spend less on soft drinks per unit.

description: The Bergman-Milton bounds provide limits on the effective permittivity of a composite material comprising two isotropic dielectric materials. These provide tight bounds for composites arising from many conventional materials. We reconsider the Bergman-Milton bounds in light of the recent emergence of metamaterials, in which unconventional parameter ranges for relative permittivities are encountered. Specifically, it is demonstrated that: (a) for nondissipative materials the bounds may be unlimited if the constituent materials have relative permittivities of opposite signs; (b) for weakly dissipative materials characterized by relative permittivities with real parts of opposite signs, the bounds may be exceedingly large.

description: Retinal artery/vein (A/V) classification plays a critical role in the clinical biomarker study of how various systemic and cardiovascular diseases affect the retinal vessels. Conventional methods of automated A/V classification are generally complicated and heavily depend on the accurate vessel segmentation. In this paper, we propose a multi-task deep neural network with spatial activation mechanism that is able to segment full retinal vessel, artery and vein simultaneously, without the pre-requirement of vessel segmentation. The input module of the network integrates the domain knowledge of widely used retinal preprocessing and vessel enhancement techniques. We specially customize the output block of the network with a spatial activation mechanism, which takes advantage of a relatively easier task of vessel segmentation and exploits it to boost the performance of A/V classification. In addition, deep supervision is introduced to the network to assist the low level layers to extract more semantic information. The proposed network achieves pixel-wise accuracy of 95.70% for vessel segmentation, and A/V classification accuracy of 94.50%, which is the state-of-the-art performance for both tasks on the AV-DRIVE dataset. Furthermore, we have also tested the model performance on INSPIRE-AVR dataset, which achieves a skeletal A/V classification accuracy of 91.6%.

description: Glass transition process gets affected in ultrathin films having thickness comparable to the size of the molecules. We observe systematic broadening of glass transition temperature (Tg) as the thickness of the polymer film reduces below the radius of gyration but the change in the average Tg was found to be very small. Existence of reversible negative and positive thermal expansion below and above Tg increased the sensitivity of our thickness measurements performed using energy dispersive x-ray reflectivity. A simple model of Tg variation as a function of depth expected from sliding motion could explain the results. We observe clear glass transition even for 4 nm polystyrene film that was predicted to be absent from ellipsometry measurements of thicker films.

description: We investigate how to theoretically and empirically incorporate demographic translating in consumer distance functions. Consumer distance functions yield inverse demand systems that are of interest when attempting to better understand questions of price formation.

Examples are included for illustrative purposes.

description: The situation that a scalar field provides the source of the accelerated expansion of the universe while rolling down its potential is common in both the simple models of the primordial inflation and the quintessence-based dark energy models. Motivated by this point, we address the possibility of causing the current acceleration via the primordial inflation using a simple model based on hybrid inflation. We trigger the onset of the motion of the quintessence field via the transition field, and find that the fate of the universe depends on the true vacuum energy determined by choosing the parameters. We also briefly discuss the variation of the equation of state and the possible implementation of our scenario in supersymmetric theories.

Tasks sequencing in mixed-model assembly systems considering workers' competencies

Publisher: name: Zenodo
Year: 2023

description: Mixed-model assembly implies several models or versions of the same product assembled on one assembly line. The models differ on some characteristics despite sharing some basic parts and operations. This implies an additional layer of complexity for production scheduling. Due to the high variability of products, mixed-model assembly lines are often manual, with operators performing most of the assembly tasks. Operators require a certain level of competency to perform each task in its standard time. Operators who are less skilled than required cannot complete tasks within standard time, while overly skilled operators perform tasks faster and vice-versa. Optimising operator assignments based on their skills can enhance overall line performance.

Most research on Mixed-Model Sequencing focuses on product sequencing and overlooks operator assignment and competence variations. Competence is typically evaluated separately for each task without considering task similarities. Task competence can be viewed as a combination of elementary competencies representing individual skills and knowledge. An operator's task competence depends on proficiency in these elementary competencies and their relevance to the task.

Our research focuses on extending the classical Mixed-Model Sequencing problem to include worker assignation and thus, the variations in process time associated with operator competencies. We achieve this by including worker assignation, competence gap and corrected process times according to competence. In addition, we consider task competence to emerge from a set of elemental competencies present throughout the process. The resulting model has an extra degree of freedom, as workers can be matched to the workstations in which they are most capable, preventing line blockages in a way impossible in the classical formulation. Future research shall focus in developing faster solution methods and evaluating the effect of considering elemental competencies.

description: This paper aims at analyzing the asymmetries in the process of globalization and its differentiated outcomes on (i) developed and less developed countries, and (ii) on LDC agriculture. The consequences of these asymmetries are reflected in the dramatic changes in world agricultural trade - an unprecedented growth of agricultural trade in real terms and a dramatic change in its composition which is increasingly moving away from bulk commodities towards high-value, processed consumer-ready agricultural goods. The impacts of these changes on LDC agriculture have been quite differentiated, with most countries experiencing a worsening of their agricultural trade balance. This change of the LDC trade position is counterintuitive if we still think of agricultural trade as a comparative-advantage-based trade, i.e. based on cost competition. It seems instead that the change in the composition of agricultural trade is the epiphenomenon of a fundamental change in the rules of the game, which are increasingly based on the reputation of agricultural products and imply a quality-based competition. Unfortunately, the implications for LDC agriculture do not seem encouraging. The intrinsic poverty of these economies, with the implied burden in terms of missing assets to compete under the new rules of the game and some adverse globalization-induced changes in LDCs macro fundamentals, are crucial handicaps that work against the development of LDC agriculture. Furthermore, the underlying forces driving globalization (increasing returns to scale, research, development of new products, etc.) undermine the traditional role of agriculture as engine of growth. The analysis carried out in this paper represents one more piece of evidence that the effects of globalization are asymmetric and that development success requires selective and phased integration with world markets. Without the required investments in terms of infrastructure, institutions, human and social capital, LDC agriculture will hardly be able to claim the expected benefits of globalization.

We comment on the extension of the calculation to next-to-next-to-leading logarithms.

description: Through empirical simulations of the Taiwanese rice market, we estimate the effects of agricultural policies designed to ensure optimal levels of two multifunctional outputs, groundwater recharge and methane emissions. The settings of policy instruments differ by region to reflect land quality and the conditions of the aquifers. The effects on rice production, resource allocation, and returns to farm assets also differ. Welfare gains are highest if transboundary costs of methane emissions are taken into account. National payments set as a weighted average of optimal regional payments may result in similar welfare gains at lower administrative costs. The costs of assistance measures to help farmers adapt to the impact of lower asset values are shown to be less than under current support policies.

description: A feed-forward neural network model is trained to calculate the nuclear charge radii. The model trained with input data set of proton and neutron number $Z,N$, the electric quadrupole transition strength $B(E2)$ from the first excited 2$^+$ state to the ground state, together with the symmetry energy. The model reproduces well not only the isotope dependence of charge radii, but also the kinks of charge radii at the neutron magic numbers $N=82$ for Sn and Sm isotopes, and also $N=126$ for Pb isotopes. The important role of $B(E2)$ value is pointed out to reproduce the kink of the isotope dependence of charge radii in these nuclei. Moreover, with the inclusion of the symmetry energy term in the inputs, the charge radii of Ca isotopes are well reproduced. This result suggests a new correlation between the symmetry energy and charge radii of Ca isotopes. The Skyrme HFB calculation is performed to confirm the existence of this correlation in a microscopic model.

description: Based on recent data collected by the UNESCO Institute of Statistics and the OECD in the context of their joint "World Education Indicators" project, labour market outcomes of education can be reassessed for selected non-OECD countries (Brazil, Chile, Indonesia, Malaysia, Peru, Thailand and Uruguay) integrating particularly interesting characteristics of developing country labour markets such as high underemployment and informal sector employment. These specific data, available by level of educational attainment, gender and age, have not yet been published and are presented for the first time within this report. Based on the new information available, some light can be shed on ongoing discussions about perceived differences between OECD and non-OECD countries with respect to labour market outcomes of education. In fact, once the important characteristics of underemployment and informal sector employment are taken into account, the link between education and labour market prospects no longer differs significantly between the two country groups. In both groups, employment prospects, earnings and labour market participation tend to be positively related to the level of educational attainment. Across all levels of education, young people and women tend to be in the most unfavourable situation. However, gender discrepancies with respect to employment prospects appear to be more important in non-OECD than in OECD countries, and no structural trend can be observed that would indicate an improvement of the situation over time.

description: We investigate the physics of an optically-driven micromotor of biological origin. A single, live red blood cell, when placed in an optical trap folds into a rod-like shape. If the trapping laser beam is circularly polarized, the folded RBC rotates. A model based on the concept of buckling instabilities captures the folding phenomenon; the rotation of the cell is simply understood using the Poincarè sphere. Our model predicts that (i) at a critical intensity of the trapping beam the RBC shape undergoes large fluctuations and (ii) the torque is proportional to the intensity of the laser beam. These predictions have been tested experimentally. We suggest a possible mechanism for emergence of birefringent properties in the RBC in the folded state.

description: Employing the light-cone sum rule approach in QCD, we relate the $B$-meson distribution amplitude to the $B\to π$ form factor at zero momentum transfer. In leading order, the sum rule is converted into a simple expression for the inverse moment $λ_B$ of the distribution amplitude $ϕ_{+}^B$. Using as an input the $B\toπ$ form factor calculated from the light-cone sum rule in terms of pion distribution amplitudes, we obtain an estimate: $λ_B =460 \pm 160 $ MeV. We investigate how this result is modified by the $B$-meson three-particle distribution amplitudes.

In this paper, we study celestial amplitudes of loop level gluons and gravitons. We focus on the rational amplitudes that carry all-plus and single-minus external helicities. Because these amplitudes are finite, they provide a concrete example of celestial amplitudes of Yang- Mills and gravity theory beyond tree level. We give explicit examples of four and five point functions and comment on higher point amplitudes.

description: The rise of Generative-AI has resulted in heated debate in the qualitative research community, with some heralding this new era with enthusiasm whilst others look at what’s occurring with horror. Whether you’re an advocate or a sceptic, come along to discuss the issues and consider whether and how it might be appropriate to integrate AI tools into the qualitative analysis workflow. This session begins by mapping the landscape; providing some historical context and outlining the three core genres AI tools in the qualitative data analysis (QDA) space: the use of general-purpose chatbot tools (such as ChatGPT and similar), a plethora of new Apps harnessing Gen-AI functionality, and the integration of Gen-AI features into established qualitative software platforms. We then focus in on how Gen-AI integrations can be used in methodologically appropriate ways to assist QDA in different contexts. Current options are outlined, demonstrated and discussed: AI Summaries, AI Code Suggestions / Coding, and AI Chatting. We then consider how and when these tools can be used appropriately and in combination with human interpretation at different stages of the analytic workflow. This includes ethical issues including model development, informed consent, and authorship, and methodological implications such as interpretive capabilities, the changing role of digital tools and collaborative analysis. 

This session is part of the 2025 IASSIST QDA Workshop Series, a year-long series exploring tools and technologies for qualitative data analysis (QDA).

Discussed in the first two sections are the history and evolution of school grounds, play and the environment, the effects of place-identity on self-identity, as well as the power of place in pedagogy. The design framework is supported by precedent studies, intending to reflect the design principles, programs, ideas and values of the ecological, curriculum-based and narrative landscape design layers. The final master plan design is an amalgamation of these three layers, representing an educational setting that will foster a dynamic interchange between children and their milieu.

description: We consider ergodic families of Verblunsky coefficients generated by minimal aperiodic subshifts. Simon conjectured that the associated probability measures on the unit circle have essential support of zero Lebesgue measure. We prove this for a large class of subshifts, namely those satisfying Boshernitzan's condition. This is accomplished by relating the essential support to uniform convergence properties of the corresponding Szego cocycles.

description: Foreign direct investment (FDI) is a crucial indicator for a country's integration into the global division of labour and its general level of development. Empirical analyses of integration processes however require an extensively harmonized procedure to compile and disseminate FDI data. This paper focuses on the question whether and to what extent a comparability of FDI data can be taken for granted. In the recent past, comparability of FDI data has improved a lot: According to IMF surveys in 2001 and 1997, the Applicant Countries (ACs) in particular were rather successful in complying with the international standards. However, a lot of problems remain, especially concerning the inclusion of indirectly owned direct investment enterprises, the comprehensive coverage of FDI components, the reporting of reverse investment and the measurement of stock data. For certain established EU countries the problem of international holding companies causes further complications. Moreover, harmonization in recent years does not necessarily mean respective ex post adjustments. So international comparisons should focus on the very recent years of more successful harmonization and always keep in mind, that deviations might, to a high extent, be due to statistical and methodological reasons.
title: Defect chemistry in perovskite titanate : from materials to interfaces

description: The increasing demand for energy consumption and environmental protection accelerates renewable energy applications. Due to the intermittence supply of renewables such as wind and wave, the development of energy conversion and storage techniques is in urgent need. H₂, with high energy density, huge reserves and zero emissions, becomes one of the most promising energy carriers in the future. High temperature steam electrolysis and photoelectrolysis are two promising methods for H₂ production that can use renewable energies like wind and solar. However, the catalysts degradation is still the main drawback for their wide application. This thesis explores a promising candidate perovskite titanate that can be used as catalyst substrates. The influences of A-site cation deficiency on materials microstructure, electronic structure and redox stability are the main issues studied in this project. This work illustrates the metal-oxide interactions enhancements when cation deficiency exists in perovskite titanate oxides. Promoted cation migration results in metal-oxide interface reconstruction, which in turn increases contact area and adhesion force between catalyst and substrate. Electron microscopy and thermogravimetry analysis showed enhanced particle stability on A-site deficient perovskite at 700 °C in redox atmosphere. The influence of cation deficiency on perovskites electronic structure was also discussed based on La and Cr co-doped SrTiO₃. Although A-site deficiency doesn’t contribute to band structure, it introduces electrons and increases carrier mobility. Thus, a dramatical enhancement in H₂ production rate was achieved in materials containing a small amount of cation deficiency. The highest H₂ production rate is 7.5 μM·h⁻¹ under visible light (>420 nm, 250 W). The reduction of perovskite in strong reducing atmosphere not only creates oxygen vacancies, but also pushes B-site cations out the lattice when A-site cation deficiency exists. Here, a series of materials doped with Fe, Co, Ni and Cu were prepared and analysed to compare the different exsolution ability. Cation size, oxygen vacancies and doping level all affect the exsolution process of transition metals. N-type conductivity due to Ti reduction suggests the possibility usage for anode material in SOFC. The initial trial with such material achieved 0.7 W·cm⁻² for single fuel cell with wet H₂ (3%H₂O) at 900 °C. Also, it can produce H₂ efficiently when working in SOEC mode. The fundamental properties of A-site deficient perovskite titanate explored in this thesis gives insight for further material design related to various functionality.
High-pT pi0, eta, Identified and Inclusive Charged Hadron Spectra from PHENIX

description: PHENIX has extended the measurement of the pi0, eta, identified and inclusive charged hadron up to 20 GeV/c, and extended the measurement to the Cu+Cu collision system. A strong suppression is observed for both pi0 and charged hadron yields in central Au+Au and Cu+Cu collisions. Comparing Au+Au and Cu+Cu systems, RAA becomes independent of pT above 5 GeV/c. Its centrality dependence is compared with two models in order to test for universal Npart scaling that is independent of system; results are inconclusive. The results are compatible with energy loss predictions. In addition, the ratio of eta to pi0 approaches, within uncertainties, a constant value of 0.4-0.5 at high pT in p+p, d+Au, and Au+Au, while the ratio of Ks to pi0 is also consistent with a constant value at high pT in d+Au and p+p. These results are compatible with normal jet fragmentation.

description: Die EU-Richtlinie 2003/87/EG zur Einführung eines europaweiten Emissionshandelssystems überlässt die Verteilung der sog. Emissionsberechtigungen an die Emittenten den einzelnen Mitgliedstaaten. In Deutschland wird diese Allokation im Zuteilungsgesetz 2007 (ZuG 2007) festgelegt, welche zahlreiche Sonderregeln enthält. Der vorliegende Report untersucht für ausgewählte Regelungen des Zuteilungsgesetzes 2007, welche ökologischen Effekte ausgelöst werden und ob es zu Wettbewerbsverzerrungen in der Stromerzeugung kommt. Es wird gezeigt, dass die Übertragungsregel (§10 ZuG 2007) auf gesamtwirtschaftlicher Ebene keinen ökologischen Nutzen stiftet und den Wettbewerb zwischen vorhandenen Betreibern fossil befeuerter Anlagen und Neuanbietern deutlich verzerrt. Die Kompensationsregel (§ 15 ZuG 2007) verfälscht den Wettbewerb zwischen den Kernkraftwerksbetreibern, die in der ersten Handelsperiode stilllegen müssen, auf der einen Seite, und ihrer Konkurrenz auf der anderen Seite. Das Zuteilungsgesetz führt in diesen Punkten zu einer ökonomisch nicht begründbaren Beeinflussung des Wettbewerbs.

description: We prove general superrigidity results for actions of irreducible lattices on CAT(0) spaces; first, in terms of the ideal boundary, and then for the intrinsic geometry (including for infinite-dimensional spaces). In particular, one obtains a new and self-contained proof of Margulis' superrigidity theorem for uniform irreducible lattices in non-simple groups. The proofs rely on simple geometric arguments, including a splitting theorem which can be viewed as an infinite-dimensional (and singular) generalization of the Lawson-Yau/Gromoll-Wolf theorem.
