description: By tackling shared problems through concerted policies, the European Union (EU) is thought to have a superior output legitimacy. However, EU policies change as they are being ‘customised’ during the implementation process. How do such patterns of ‘differentiated implementation’ affect EU governance in practice? While some studies highlight the danger of ‘watering down’ the objectives of EU law, others emphasise the role of decentralised problem-solving. We analyse how customisation affects states’ practical compliance with EU anti-discrimination, environmental, and justice and home affairs directives in 27 member states (excluding Croatia) between 2007 and 2013. The findings show that customised density (higher number of rules than prescribed by the EU directives) reduces practical compliance. Conversely, customised restrictiveness (stricter requirements than the EU directives) improves practical compliance. In contrast to earlier implementation research, we conclude that literal implementation is not the best form to ensure practical implementation.

Multiple electron-hole scattering effect on quasiparticle properties in a homogeneous electron gas

description: We present a detailed study of a contribution of the T matrix accounting for multiple scattering between an electron and a hole to the quasiparticle self-energy. This contribution is considered as an additional term to the GW self-energy. The study is based on a variational solution of the T-matrix integral equation within a local approximation. A key quantity of such a solution, the local electron-hole interaction, is obtained at the small four-momentum transfer limit. Performed by making use of this limit form, extensive calculations of quasiparticle properties in the homogeneous electron gas over a broad range of electron densities are reported. We carry out an analysis of how the T-matrix contribution affects the quasiparticle damping rate, the quasiparticle energy, the renormalization constant, and the effective mass enhancement. We find that in comparison with the GW approximation the inclusion of the T matrix leads to an essential increase of the damping rate, a slight reduction of the GW band narrowing, a decrease of the renormalization constant at the Fermi wave vector, and some "weighting" of quasiparticles at the Fermi surface.

FUEL PREHEATING FOR IMPROVING THE PERFORMANCE OF IC ENIGNE
Creators: name: PSG College of Technology
Publisher: name: Zenodo
Year: 2025
Subjects: AUTOMOBILE ENGINEERING

description: This study presents a passive fuel preheating system designed to enhance combustion efficiency in internal combustion engines by utilizing exhaust gas heat recovery. The system employs a copper coil wound around a secondary fuel tank, through which hot exhaust gases are directed. As the gases flow through the coil, thermal energy is transferred to the fuel, raising its temperature prior to combustion. Preheated fuel exhibits lower viscosity, resulting in improved atomization, more efficient combustion, and reduced emissions. The setup includes two fuel tanks—one standard and one preheated—to allow performance comparisons. This method eliminates the need for external power sources and leverages otherwise wasted thermal energy, making it a cost-effective and energy-efficient solution. Experimental observations indicate potential improvements in fuel economy and engine performance. The system is particularly suitable for small to medium-capacity engines, offering a practical approach to enhancing thermal efficiency through waste heat utilization.

description: We discuss a model comprising two coupled nonlinear oscillators (Kerr-like nonlinear coupler) with one of them pumped by an external coherent excitation. Applying the method of nonlinear quantum scissors we show that the quantum evolution of the coupler can be closed within a finite set of n-photon Fock states. Moreover, we show that the system is able to generate Bell-like states and, as a consequence, the coupler discussed behaves as a two-qubit system. We also analyze the effects of dissipation on entanglement of formation parametrized by concurrence.

The sacred vs. the secular : evangelical Christian psychologists’ religious values and ethical practice
Creators: name: Irvine, Kathleen A.
Publisher: name: University of British Columbia
Year: 2009

description: Evangelical Christian psychologists sometimes experience tension between their religious and moral values and the values represented by the ethics codes of their professional associations. A qualitative study, using the Critical Incident Technique (CIT), was done to explore the question: "What factors help or hinder evangelical Christian psychologists in dealing with the tensions they experience between their religious moral values and the ethics of professional psychological practice as embodied in professional ethics codes?" Twelve participants identified a variety of tensions and factors that helped and hindered in resolving these tensions. Their responses were categorized into 306 incidents, which were organized into 13 helping categories and 5 hindering categories. Experiencing support, engaging in a process of self-reflection, acquiring knowledge, being open to God, and being clear on beliefs and roles were the primary factors that helped participants deal with these tensions.

The cross-wind excitation of bluff structures and the incident turbulence mechanism
Creators: name: Jancauskas, Erin Douglas
Publisher: name: Monash University
Year: 2020
Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: The excitation of a structure by wind action can be conveniently considered under the divisions 'along-wind excitation' and 'cross-wind excitation'. In the case of along-wind excitation, it has been shown (primarily from the work of Davenport [1967] and Vickery [1971]) that the excitation results almost entirely from the action of the longitudinal velocity fluctuations. As a result, analytical prediction techniques for along-wind excitation have become highly developed.On the other hand, the cross-wind excitation process has proved to be extremely complex and, as Melbourne points out in his 1975 review paper on cross-wind aerodynamics, there is as yet no generalised analytical method available to calculate the cross-wind response of structures. This is despite the fact that the cross-wind excitation is often the major source of excitation for many real structures, such as bridge decks and tall buildings.

description: This article assesses how trilogues affect the possibilities to hold the European Parliament to account from the perspectives of democracy as political equality and democracy as epistemic quality. Trilogues, informal and secluded meetings between a limited number of participants, have become standard operating procedure for reaching legislative decisions in the EU. Trilogues are defended because they provide efficient settings where decision-makers can discuss more freely but are also criticised for hindering open and inclusive decision-making processes. Despite recent rule reforms, we argue that the democratic problem with trilogues is not their informal or secluded character per se, but that the compromises reached in these settings are not sufficiently linked to or discussed among the collective of MEPs in arenas where external actors have access to legislators’ arguments and debates. When internal and external accountability is not linked, legislative proposals are deprived of sufficient democratic authorisation.
Spin Hall effect and zitterbewegung in an electron waveguide

description: We study spin-resolved probability distributions for electrons in a multichannel waveguide in the presence of a spin-orbit interaction. For a spin-polarized electron injection, a zitterbewegung pattern is predicted in the probability distribution of electrons in the waveguide. For a spin-unpolarized injection, the spin-resolved electron probability in the waveguide shows spin accumulations. In addition to the spin Hall phenomenon, namely accumulations of opposite spins at the lateral edges of the waveguide, we predict the existence of a regular stripe pattern of spin accumulations in the internal region of the waveguide. We show that the predicted zitterbewegung and spin Hall effect stem from the same mechanism and are formed from coherent states of electrons in the waveguide.

description: Improving upon the previous treatment by Mueller and Son, we derive the Boltzmann equation that results from a classical scalar field theory. This is obtained by starting from the corresponding quantum field theory and taking the classical limit with particular emphasis on the path integral and perturbation theory. A previously overlooked Van-Vleck determinant is shown to control the tadpole type of self-energy that can still appear in the classical perturbation theory. Further comments on the validity of the approximations and possible applications are also given.

Solving Kepler's equation with CORDIC double iterations

description: In a previous work, we developed the idea to solve Kepler's equation with a CORDIC-like algorithm, which does not require any division, but still multiplications in each iteration. Here we overcome this major shortcoming and solve Kepler's equation using only bitshifts, additions, and one initial multiplication. We prescale the initial vector with the eccentricity and the scale correction factor. The rotation direction is decided without correction for the changing scale. We find that double CORDIC iterations are self-correcting and compensate possible wrong rotations in subsequent iterations. The algorithm needs 75\% more iterations and delivers the eccentric anomaly and its sine and cosine terms times the eccentricity. The algorithm can be adopted for the hyperbolic case, too. The new shift-and-add algorithm brings Kepler's equation close to hardware and allows to solve it with cheap and simple hardware components.

Minimax determination of the energy spectrum of the Dirac equation in a Schwarzschild background

description: We calculate the bound-state energy spectrum of the Dirac Equation in a Schwarzschild black hole background using a minimax variational method. Our method extends that of Talman to the case of non-Hermitian interactions, such as a black hole. The trial function is expressed in terms of a basis set that takes into account both the Hermitian limit of the interaction in the non-relativistic approximation, and the general behaviour of the solutions at the origin, the horizon and infinity. Using this trial function an approximation to the full complex energy bound-state spectrum is computed. We study the behaviour of the method as the coupling constant of the interaction is increased, which increases both the relativistic effects and the size of the non-Hermitian part of the interaction. Finally we confirm that the method follows the expected Hylleraas-Undheim behaviour.

description: Increasing demand for on-device Automatic Speech Recognition (ASR) systems has resulted in renewed interests in developing automatic model compression techniques. Past research have shown that AutoML-based Low Rank Factorization (LRF) technique, when applied to an end-to-end Encoder-Attention-Decoder style ASR model, can achieve a speedup of up to 3.7x, outperforming laborious manual rank-selection approaches. However, we show that current AutoML-based search techniques only work up to a certain compression level, beyond which they fail to produce compressed models with acceptable word error rates (WER). In this work, we propose an iterative AutoML-based LRF approach that achieves over 5x compression without degrading the WER, thereby advancing the state-of-the-art in ASR compression.

description: We performed numerical simulations of decaying quantum turbulence by using a generalized Gross-Pitaevskii equation, that includes a beyond mean field correction and a nonlocal interaction potential. The nonlocal potential is chosen in order to mimic He II by introducing a roton minimum in the excitation spectrum. We observe that at large scales the statistical behavior of the flow is independent of the interaction potential, but at scales smaller than the intervortex distance a Kelvin wave cascade is enhanced in the generalized model. In this range, the incompressible kinetic energy spectrum obeys the weak wave turbulence prediction for Kelvin wave cascade not only for the scaling with wave numbers but also for the energy fluxes and the intervortex distance.

description: Irradiation of solids with ultrashort pulses and laser processing in the mid-Infrared (mid-IR) spectral region is a yet predominantly unexplored field with a large potential for a wide range of applications. In this work, laser driven physical phenomena associated with processes following irradiation of fused silica (SiO2) with ultrashort laser pulses in the mid-IR region are investigated in detail. A multiscale modelling approach is performed that correlates conditions for formation of perpendicular or parallel to the laser polarisation low spatial frequency periodic surface structures for low and high intensity mid-IR pulses (not previously explored in dielectrics at those wavelengths), respectively. Results demonstrate a remarkable domination of tunneling effects in the photoionisation rate and a strong influence of impact ionisation for long laser wavelengths. The methodology presented in this work is aimed to shed light on the fundamental mechanisms in a previously unexplored spectral area and allow a systematic novel surface engineering with strong mid-IR fields for advanced industrial laser applications.

X-ray Emission Properties of Large Scale Jets, Hotspots and Lobes in Active Galactic Nuclei

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: We examine a systematic comparison of jet-knots, hotspots and radio lobes recently observed with Chandra and ASCA. This report will discuss the origin of their X-ray emissions and investigate the dynamics of the jets. The data was compiled at well sampled radio (5GHz) and X-ray frequencies (1keV) for more than 40 radio galaxies. We examined three models for the X-ray production: synchrotron (SYN), synchrotron self-Compton (SSC) and external Compton on CMB photons (EC). For the SYN sources -- mostly jet-knots in nearby low-luminosity radio galaxies -- X-ray photons are produced by ultrarelativistic electrons with energies 10-100 TeV that must be accelerated in situ. For the other objects, conservatively classified as SSC or EC sources, a simple formulation of calculating the ``expected'' X-ray fluxes under an equipartition hypothesis is presented. We confirmed that the observed X-ray fluxes are close to the expected ones for non-relativistic emitting plasma velocities in the case of radio lobes and majority of hotspots, whereas considerable fraction of jet-knots is too bright at X-rays to be explained in this way. We examined two possibilities to account for the discrepancy in a framework of the inverse-Compton model: (1) magnetic field is much smaller than the equipartition value, and (2) the jets are highly relativistic on kpc/Mpc scales. We concluded, that if the inverse-Compton model is the case, the X-ray bright jet-knots are most likely far from the minimum-power condition. We also briefly discuss the other possibility, namely that the observed X-ray emission from all of the jet-knots is synchrotron in origin.

description: Effective Lagrangian models of charmonium have recently been used to estimate dissociation cross sections with light hadrons. Detailed study of the symmetry properties reveals possible shortcomings relative to chiral symmetry. We therefore propose a new Lagrangian and point out distinguishing features amongst the different approaches. Moreover, we test the models against Adler's theorem, which requires, in the appropriate limit, the decoupling of pions from the theory for the normal parity sector. Using the newly proposed Lagrangian, which exhibits SU_L(N_f) x SU_R(N_f) symmetry and complies with Adler's theorem, we find dissociation cross sections with pions that are reduced in an energy dependent way, with respect to cases where the theorem is not fulfilled.

Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to investigate the reading comprehension problems associated with hyperlexia in young children. Two 8-year-old children with hyperlexia and two children with mild intellectual delays (MID), matched in terms of age, grade, and IQ, were evaluated using various decoding and reading comprehension tasks. Children with hyperlexia had excellent decoding abilities, far above what would be expected for their cognitive level, but did not comprehend passages as well as students without hyperlexia who had similar cognitive ability. Prior knowledge aided the reading comprehension for the MID participants, where as high interest strongly aided the comprehension for the hyperlexia participants. Students with hyperlexia demonstrated less comprehension monitoring than the MID students. Results are discussed with regards to implications for teaching children with hyperlexia and MID.

description: Magnetic shields that use both active and passive components to enable the generation of a tailored low-field environment are required for many applications in science, engineering, and medical imaging. Until now, accurate field nulling, or field generation, has only been possible over a small fraction of the overall volume of the shield. This is due to the interaction between the active field-generating components and the surrounding high-permeability passive shielding material. In this paper, we formulate the interaction between an arbitrary static current flow on a cylinder and an exterior closed high-permeability cylinder. We modify the Green's function for the magnetic vector potential and match boundary conditions on the shield's interior surface to calculate the total magnetic field generated by the system. We cast this formulation into an inverse optimization problem to design active--passive magnetic field shaping systems that accurately generate any physical static magnetic field in the interior of a closed cylindrical passive shield. We illustrate this method by designing hybrid systems that generate a range of magnetic field profiles to high accuracy over large interior volumes, and simulate them in real-world shields whose passive components have finite permeability, thickness, and axial entry holes. Our optimization procedure can be adapted to design active--passive magnetic field shaping systems that accurately generate any physical user-specified static magnetic field in the interior of a closed cylindrical shield of any length, enabling the development and miniaturization of systems that require accurate magnetic shielding and control.

description: This paper estimates the effect of environmental regulation on industry location and compares it with other determinants of location such as agricultural, education and R&D country characteristics. The analysis is based on a general empirical trade model that captures the interaction between country and industry characteristics in determining industry location. The Johnson-Neyman technique is used to fully explicate the nature of the conditional interactions. The model is applied to data on 16 manufacturing industries from 13 European countries. The empirical results indicate that the pollution haven effect is present and that the relative strength of such an effect is of about the same magnitude as other determinants of industry location. A significant negative effect on industry location is observed only at relatively high levels of industry pollution intensity.

Positivity Bounds and the Massless Spin-2 Pole

description: The presence of a massless spin-2 field in an effective field theory results in a $t$-channel pole in the scattering amplitudes that precludes the application of standard positivity bounds. Despite this, recent arguments based on compactification to three dimensions have suggested that positivity bounds may be applied to the $t$-channel pole subtracted amplitude. If correct this would have deep implications for UV physics and the Weak Gravity Conjecture. Within the context of a simple renormalizable field theory coupled to gravity we find that applying these arguments would constrain the low-energy coupling constants in a way which is incompatible with their actual values. This contradiction persists on deforming the theory. Further enforcing the $t$-channel pole subtracted positivity bounds on such generic renormalizable effective theories coupled to gravity would imply new physics at a scale parametrically smaller than expected, with far reaching implications. This suggests that generically the standard positivity bounds are inapplicable with gravity and we highlight a number of issues that impinge on the formulation of a three-dimensional amplitude which simultaneously satisfies the required properties of analyticity, positivity and crossing symmetry. We conjecture instead a modified bound that ought to be satisfied independently of the precise details of the high energy completion.

description: Motivated by the BPS/CFT correspondence, we explore the similarities between the classical $β$-deformed Hermitean matrix model and the $q$-deformed matrix models associated to 3d $\mathcal{N}=2$ supersymmetric gauge theories on $D^2\times_{q}S^1$ and $S_b^3$ by matching parameters of the theories. The novel results that we obtain are the correlators for the models, together with an additional result in the classical case consisting of the $W$-algebra representation of the generating function. Furthermore, we also obtain surprisingly simple expressions for the expectation values of characters which generalize previously known results.

description: We consider QCD radiative corrections to WW pair production in hadron collisions. We perform a calculation that consistently combines next-to-leading order predictions with soft-gluon resummation valid at small transverse momenta ptWW of the WW pair. We present results for the ptWW distribution at the LHC up to (almost) next-to-next-to-leading logarithmic accuracy, and study the effect of resummation on the charged-lepton distributions. Soft-gluon effects are typically mild, but they can be strongly enhanced when hard cuts are applied. The relevant distributions are generally well described by the MC@NLO event generator.

description: What is the rate at which people discount future lives saved? The answer to this question has important implications when comparing policies on the grounds of cost per life saved, especially in the context of hazardous waste site remediation, where risk reductions may occur at different times, depending on the permanence of the remedy. We estimate this rate by asking a sample of Italian residents to choose between saving 100 lives now and X lives in T years, where both X and T are varied to the respondents. Assuming constant exponential discounting, the responses to these questions imply a rate of time preference for saving lives of 12%. There is little evidence that this rate is systematically associated with observable individual characteristics of the respondent. There is, however, strong evidence that it declines with the time horizon when the lives would be saved, ranging from 16% for T=10 to less than 4% for T³40. We fit a hyperbolic discount model, finding that it yields a similar value of the discount function for T=10 (the shortest horizon we used in the survey), and that it discounts the future less heavily than the regular exponential discounting model for longer time horizon. We apply our estimated discount functions to two alternate remedial plans for a heavily contaminated area in Italy, and find that—due to the high estimated discount rates—the less permanent solution is found to be more cost-effective.

From Coffee Beans to Microchips: Export Diversification and Economic Growth in Costa Rica

Subjects: International Relations/Trade

description: During the early 1980s Costa Rica experienced its worst economic crisis since World War II, which led to the abandonment of the import substitution model of development adopted in the 1960s. This severe economic downturn also spurred the implementation of a series of new policies supporting foreign investment in high-value-added industries and the diversification of the nation’s exports. As a result, Costa Rica has diversified its economic activity, moved away from its historical dependence on agricultural exports, and gained new competitive advantages in the manufacturing sector. This study presents a straightforward generalization of the model proposed by Herzer and Nowak-Lehnmann’s (2006) to test the hypothesis that export diversification has influenced economic growth in Costa Rica via externalities of learning-by-exporting and learning-by-doing. To examine whether a long-run relationship exists between export diversification and economic growth, two types of statistical methodologies are used: the bounds test to cointegration within a distributed lag (ARDL) framework and the dynamic OLS (DOLS). Overall results sufficiently conclude that, at least in the Granger’s sense, there is no long-run causality between export diversification and economic growth in Costa Rica over the period of 1965 to 2006.

description: Between 1983 and 1992, the Australian Centre for International Agricultural Research (ACIAR) invested A$3 million in research to find a vaccine that could provide protection from Newcastle disease in chickens and be applied in village environments in developing countries. A further $160 000 was invested in follow up projects which ended in 1996. Village chickens often provide the only source of protein to poor villagers living in remote areas and Newcastle disease frequently devastates unvaccinated village flocks. The ACIAR-sponsored research was highly successful in developing a heat resistant vaccine (HRV4) which could be readily used in the field by coating it onto chicken feed. The vaccine was commercialised by an Australian company which subsequently was taken over by an American firm. Uptake of that technology has been somewhat limited to date. The capacity of poor villagers to pay for vaccine is limited, and logistical problems have been encountered in transporting and storing large quantities of vaccine-coated grain. Having perceived these problems, ACIAR sponsored further research which led to the production of a new, uncommercialised vaccine, I2. Quantities of the seed of this vaccine are now being sent to many countries, particularly in Africa. From this seed vaccine the heat resistant vaccine can be made locally and applied to chickens in drinking water or by eye drops. The results of this analysis indicate that on the basis of conservative assumptions, the benefits from the research have already outweighed the costs. In the longer term, the discounted net present value of the research is estimated at $211 million. Malaysia and Vietnam have been the major beneficiaries to date, but large benefits are also expected in Africa.
Nonlinear entanglement witnesses

description: Entanglement detection typically relies on linear inequalities for mean values of certain observables (entanglement witnesses), where violation indicates entanglement. We provide a general method to improve any of these inequalities for bipartite systems via nonlinear expressions. The nonlinearities are of different orders and can be directly measured in experiments, often without any extra effort.

description: The introduction of accelerator devices such as graphics processing units (GPUs) has had profound impact on molecular dynamics simulations and has enabled order-of-magnitude performance advances using commodity hardware. To fully reap these benefits, it has been necessary to reformulate some of the most fundamental algorithms, including the Verlet list, pair searching and cut-offs. Here, we present the heterogeneous parallelization and acceleration design of molecular dynamics implemented in the GROMACS codebase over the last decade. The setup involves a general cluster-based approach to pair lists and non-bonded pair interactions that utilizes both GPUs and CPU SIMD acceleration efficiently, including the ability to load-balance tasks between CPUs and GPUs. The algorithm work efficiency is tuned for each type of hardware, and to use accelerators more efficiently we introduce dual pair lists with rolling pruning updates. Combined with new direct GPU-GPU communication as well as GPU integration, this enables excellent performance from single GPU simulations through strong scaling across multiple GPUs and efficient multi-node parallelization.

description: We adapt a non-linear filter proposed by Hu 2001 for detecting lensing of the CMB by large-scale structures to recover surface-density profiles of galaxy clusters from their localised, weak gravitational lensing effect on CMB fields. Shifting the band-pass of the filter to smaller scales, and normalising it such as to reproduce the convergence rather than the deflection angle, we find that the mean density profile of a sample of 100 clusters can be recovered to better than 10% from well within the scale radius to almost the virial radius. The kinetic Sunyaev-Zel'dovich effect is shown to be a negligible source of error. We test the filter applying it to data simulated using the characteristics of the Atacama Cosmology Telescope (ACT), showing that it will be possible to recover mean cluster profiles outside a radius of 1' corresponding to ACT's angular resolution.
