description: Phase retrieval (PR) aims to recover a signal from the magnitudes of a set of inner products. This problem arises in many audio signal processing applications which operate on a short-time Fourier transform magnitude or power spectrogram, and discard the phase information. Recovering the missing phase from the resulting modified spectrogram is indeed necessary in order to synthesize time-domain signals. PR is commonly addressed by considering a minimization problem involving a quadratic loss function. In this paper, we adopt a different standpoint. Indeed, the quadratic loss does not properly account for some perceptual properties of audio, and alternative discrepancy measures such as beta-divergences have been preferred in many settings. Therefore, we formulate PR as a new minimization problem involving Bregman divergences. Since these divergences are not symmetric with respect to their two input arguments in general, they lead to two different formulations of the problem. To optimize the resulting objective, we derive two algorithms based on accelerated gradient descent and alternating direction method of multipliers. Experiments conducted on audio signal recovery from spectrograms that are either exact or estimated from noisy observations highlight the potential of our proposed methods for audio restoration. In particular, leveraging some of these Bregman divergences induce better performance than the quadratic loss when performing PR from spectrograms under very noisy conditions.

description: We propose a scheme to enhance quantum entanglement in an optomechanical system by exploiting the so-called Duffing nonlinearity. Our model system consists of two mechanically coupled mechanical resonators, both driven by an optical field. One resonator supports Duffing nonlinearity, while the other does not.The resonators are coupled to each other via the so-called phonon hopping mechanism. The hopping rate is $θ$-phase-dependent that induces Exceptional Points (EPs) singularities in the system. Interestingly, while the resonator with Duffing nonlinearity exhibits vanishing entanglement with light, we observe an increase in entanglement between light and the other mechanical resonator. This enhanced entanglement persists longer against thermal fluctuations compared to the one without the nonlinearity. Additionally, this entanglement features a sudden death and revival phenomenon, where the peaks happen at the multiple of $θ=\fracπ{2}$. This work opens a new avenue for exploiting nonlinear resources to generate strong quantum entanglement, paving the way for advancements in quantum information processing, quantum sensing, and quantum computing within complex systems.

description: Transmission lines are excellent examples of quantum simulators of quantum fields. By appropriately driving specific circuit elements, these devices can reproduce relativistic and quantum such as particle creation due to the non-adiabatic stimulation of the quantum vacuum. We investigate particle creation in left-handed transmission lines induced by the modulation of the Josephson energy in superconducting quantum interference devices. Our results show that, as a consequence of the peculiar dispersion relations present in these systems, particle production occurs with much more favorable conditions with respect to the usual right-handed transmission lines.

description: The extraordinary sensitivity of plasmonic sensors is well known in the optics and photonics community. These sensors exploit simultaneously the enhancement and the localization of electromagnetic fields close to the interface between a metal and a dielectric. This enables, for example, the design of integrated biochemical sensors at scales far below the diffraction limit. Despite their practical realization and successful commercialization, the sensitivity and associated precision of plasmonic sensors are starting to reach their fundamental classical limit given by quantum fluctuations of light -- known as the shot-noise limit. To improve the sensing performance of these sensors beyond the classical limit, quantum resources are increasingly being employed. This area of research has become known as `quantum plasmonic sensing' and it has experienced substantial activity in recent years for applications in chemical and biological sensing. This review aims to cover both plasmonic and quantum techniques for sensing, and shows how they have been merged to enhance the performance of plasmonic sensors beyond traditional methods. We discuss the general framework developed for quantum plasmonic sensing in recent years, covering the basic theory behind the advancements made, and describe the important works that made these advancements. We also describe several key works in detail, highlighting their motivation, the working principles behind them, and their future impact. The intention of the review is to set a foundation for a burgeoning field of research that is currently being explored out of intellectual curiosity and for a wide range of practical applications in biochemistry, medicine, and pharmaceutical research.

description: Quantum entanglement is essential to the development of quantum computation, communications, and technology. The controlled SWAP test, widely used for state comparison, can be adapted to an efficient and useful test for entanglement of a pure state. Here we show that the test can evidence the presence of entanglement (and further, genuine n-qubit entanglement), can distinguish entanglement classes, and that the concurrence of a two-qubit state is related to the test's output probabilities. We also propose a multipartite measure of entanglement that acts similarly for n-qubit states. The number of copies required to detect entanglement decreases for larger systems, to four on average for many (n>8) qubits for maximally entangled states. For non-maximally entangled states, the average number of copies of the test state required to detect entanglement increases with decreasing entanglement. Furthermore, the results are robust to second order when typical small errors are introduced to the state under investigation.

description: In the European Union member states (EU), it is necessary to evaluate hygienic condition of milk in order to determine milk price. Similar requirement was set by the Republic of Croatia in 2000. The Rulebook defines minimal quality criteria that fresh raw milk must have in order to be purchased. Upon completion of analysis, milk is classified into quality classes, each having a defined price. Increased value of somatic cell count (SCC) (higher than 400.000/ml) and MO (higher than 100.000/ml) directly decreases the raw milk price, while higher content of fat and protein causes its increase. Since the system of market milk price formation was established, producers have been stimulated to produce milk of higher quality: in a total of milk being purchased, the highest quality milk share increased from 23.3% to 34.2%. Referring to a trend of milk purchase price reduction in the EU, and considering the current high milk purchase price in Croatia, Croatian producers have an opportunity to improve conditions in milk industry before the country joins the EU. Current milk production needs to be increased and milk quality also needs to be improved, in order to make Croatian milk production more competitive on the European, as well as world market.

description: Real magnonic crystals - periodic magnetic media for spin wave (magnon) propagation - may contain some defects. We report theoretical spin wave spectra of a one dimensional magnonic crystal with an isolated defect. The latter is modeled by insertion of an additional layer with thickness and magnetic anisotropy values different from those of the magnonic crystal constituent layers. The defect layer leads to appearance of several localized defect modes within the magnonic band gaps. The frequency and the number of the defect modes may be controlled by varying parameters of the constituent layers of the magnonic crystal.

description: In a classically chaotic system that is ergodic, any trajectory will be arbitrarily close to any point of the available phase space after a long time, filling it uniformly. Using Born's rules to connect quantum states with probabilities, one might then expect that all quantum states in the chaotic regime should be uniformly distributed in phase space. This simplified picture was shaken by the discovery of quantum scarring, where some eigenstates are concentrated along unstable periodic orbits. Despite of that, it is widely accepted that most eigenstates of chaotic models are indeed ergodic. Our results show instead that all eigenstates of the chaotic Dicke model are actually scarred. They also show that even the most random states of this interacting atom-photon system never occupy more than half of the available phase space. Quantum ergodicity is achievable only as an ensemble property, after temporal averages are performed.

description: It is not yet understood whether the implementation of traceability systems can contribute towards restoring consumer confidence in food quality and safety, one of the goals of the European Food Law. To date, little is known about how consumers perceive the role and potential impact of traceability within the supply chain. This paper aims to provide insight into how traceability information can offer guarantees of food quality and safety, and contribute towards increased consumer confidence. Data, collected in four EU countries, examines salient cognitions and attitudes that underpin consumer beliefs about product traceability that will influence their decision making. It will link traceability- related food attributes to perceived benefits (in terms of quality and safety) and important consumer values. Furthermore, variations between different consumer s are examined to illustrate how the concepts of food safety and food quality may have different meanings and consequences in the various European countries. Understanding which benefits consumer s associate with traceability will assist in providing consumers with traceability information in line with their requirement s.

description: Gaussian Splatting has emerged as a prominent model for constructing 3D representations from images across diverse domains. However, the efficiency of the 3D Gaussian Splatting rendering pipeline relies on several simplifications. Notably, reducing Gaussian to 2D splats with a single view-space depth introduces popping and blending artifacts during view rotation. Addressing this issue requires accurate per-pixel depth computation, yet a full per-pixel sort proves excessively costly compared to a global sort operation. In this paper, we present a novel hierarchical rasterization approach that systematically resorts and culls splats with minimal processing overhead. Our software rasterizer effectively eliminates popping artifacts and view inconsistencies, as demonstrated through both quantitative and qualitative measurements. Simultaneously, our method mitigates the potential for cheating view-dependent effects with popping, ensuring a more authentic representation. Despite the elimination of cheating, our approach achieves comparable quantitative results for test images, while increasing the consistency for novel view synthesis in motion. Due to its design, our hierarchical approach is only 4% slower on average than the original Gaussian Splatting. Notably, enforcing consistency enables a reduction in the number of Gaussians by approximately half with nearly identical quality and view-consistency. Consequently, rendering performance is nearly doubled, making our approach 1.6x faster than the original Gaussian Splatting, with a 50% reduction in memory requirements.

description: The global health impact of the COVID-19 pandemic has been devastating, particularly for vulnerable populations. This study delves into the question of whether centenarians and semi-supercentenarians, who belong to an extremely vulnerable segment of the population, experienced greater protection during the pandemic. By analyzing monthly Italian mortality data categorized by age-groups, sex, macroregions, and comparing pre-pandemic and pandemic years, this research aims to uncover differential responses among various age-groups during the COVID-19 pandemic. To estimate excess mortality for different age-groups, macroregions, and pandemic waves, a Poisson model incorporating temporal trends and seasonal components is employed. The study reveals that during the initial phase of the pandemic, all age-groups experienced a notable increase in mortality, with evi-dent spatial heterogeneity across the country. However, in subsequent waves, the pandemic affected the entire Italian territory surprisingly sparing centenarians and semi-supercentenarians. This suggests that these vulnerable age-groups may have received comparatively greater protection during the later stages of the pandemic. By enhancing our comprehension of the intricate interplay between COVID-19 and population vulnerability, this study has valuable implications for formulating public health interventions and policies that prioritize the protection of the most suscep tible individuals in subsequent waves of the pandemic or comparable health emergencies.

description: The Barcelona Agreement was signed in 1995, setting forth a structure with bilateral agreements between the EU and twelve Mediterranean countries. The agreement also foresaw the creation of a free trade area in the Euro-Mediterranean region by 2010. For many of the countries surrounding the Mediterranean sea, fruit and vegetables are very important products. In light of the increasing trade liberalization and thus increasing competition between countries, this paper aims to investigate further the competitiveness of Mediterranean countries with respect to fresh fruit and vegetables. The results generally show that the competitiveness of the investigated countries has deteriorated over the period. In only two cases, there is an increase in competitiveness.

description: Two-dimensional (2D) layered materials, demonstrating significantly different properties from their bulk counterparts, offer a materials platform with potential applications from energy to information processing devices. Although some single- and few-layer forms of materials such as graphene and transition metal dichalcogenides have been realized and thoroughly studied, the space of arbitrarily layered assemblies is still mostly unexplored. The main goal of this work is to demonstrate precise control of layered materials' electronic properties through careful choice of the constituent layers, their stacking, and relative orientation. Physics-based and AI-driven approaches for the automated planning, execution, and analysis of electronic structure calculations are applied to layered assemblies based on prototype one-dimensional (1D) materials and realistic 2D materials. We find it is possible to routinely generate moiré band structures in 1D with desired electronic characteristics such as a band gap of any value within a large range, even with few layers and materials (here, four and six, respectively). We argue that this tunability extends to 2D materials by showing the essential physical ingredients are already evident in calculations of two-layer MoS$_2$ and multi-layer graphene moiré assemblies.

Porous sand-asphalts possess the same attributes as other porous, bituminous mixtures. Surely, sand-asphalt mixtures, can be designed to be as porous as the so-called, open-graded plantmix seals. Particle shape and texture otherwise define skid-resistance. Stability remains an assurance against scaling. Stability is assured by maximum utilization of filler-bitumen ratio and the stiffness of asphalt cement.

description: Enterobacter sakazakii, a pathogen that can be found in powdered infant milk formula, can cause adverse health effects on infants. Using Vickrey auction, this study examines parents' willingness to pay (WTP) for a quality assurance label on powdered infant milk formula. The influence of ambiguity with the incidence rate information and provision of safe-handling information on WTP are also evaluated using three experiments/treatments. The mean price premium parents are willing to pay for the safer and quality assurance labelled powdered infant milk formula ranges from 61 to 133 Eurocents per 100 grams depending on the treatment. While no ambiguity effects are generally found, provision of safe-handling information has a significant influence on WTP. When the safe-handling information was given, WTP for the quality assurance label was significantly reduced and ranged from 39 to 69 Eurocents per 100 grams depending on the treatment. The results suggest that parents significantly value a quality assurance label with or without clear incidence rate information. Parents' valuation of the label, however, is reduced with the provision of safe-handling information.

description: We summarise recent results on the properties of gluons, quarks and light mesons from the Green's functions approach to QCD. We discuss a self-consistent, infrared power law solution for the Schwinger-Dyson equations of the 1PI-Greens functions of Yang-Mills theory. The corresponding running coupling has a universal fixed point at zero momentum. Based on these analytical results a truncation scheme for the coupled system of Schwinger-Dyson equations for the propagators of QCD and the Bethe-Salpeter equation for light mesons has been formulated. We compare numerical results for charge eigenstate vector and pseudoscalar meson observables with corresponding lattice data. The effects of unquenching the system are found to be small but not negligible.

description: In this paper, we tackle a persistent numerical instability within the total Lagrangian smoothed particle hydrodynamics (TLSPH) solid dynamics. Specifically, we address the hourglass modes that may grow and eventually deteriorate the reliability of simulation, particularly in the scenarios characterized by large deformations. We propose a generalized essentially non-hourglass formulation based on volumetric-deviatoric stress decomposition, offering a general solution for elasticity, plasticity, anisotropy, and other material models. Comparing the standard SPH formulation with the original non-nested Laplacian operator applied in our previous work \cite{wu2023essentially} to handle the hourglass issues in standard elasticity, we introduce a correction for the discretization of shear stress that relies on the discrepancy produced by a tracing-back prediction of the initial inter-particle direction from the current deformation gradient. The present formulation, when applied to standard elastic materials, is able to recover the original Laplacian operator. Due to the dimensionless nature of the correction, this formulation handles complex material models in a very straightforward way. Furthermore, a magnitude limiter is introduced to minimize the correction in domains where the discrepancy is less pronounced. The present formulation is validated, with a single set of modeling parameters, through a series of benchmark cases, confirming good stability and accuracy across elastic, plastic, and anisotropic materials. To showcase its potential, the formulation is employed to simulate a complex problem involving viscous plastic Oobleck material, contacts, and very large deformation.

description: The "Disk Substructures at High Angular Resolution Project" (DSHARP) has revealed an abundance and ubiquity of rings and gaps over a large sample of young planet-forming disks, which are hypothesised to be induced by the presence of forming planets. In this context, we present the first attempt to directly image these young companions for 10 of the DSHARP disks, by using NaCo/VLT high contrast observations in L'-band instrument and angular differential imaging techniques. We report the detection of a point-like source candidate at 1.1" (174.9 au) for RU Lup, and at 0.42" (55 AU) for Elias 24. In the case of RU Lup, the proper motion of the candidate is consistent with a stationary background contaminant, based on the astrometry derived from our observations and available archival data. For Elias 24 the point-like source candidate is located in one of the disk gaps at 55 AU. Assuming it is a planetary companion, our analysis suggest a mass ranging from $0.5 M_J$ up to $5 M_J$, depending on the presence of a circumplanetary disk and its contribution to the luminosity of the system. However, no clear confirmation is obtained at this stage, and follow-up observations are mandatory to verify if the proposed source is physical, comoving with the stellar host, and associated with a young massive planet sculpting the gap observed at 55\,AU. For all the remaining systems, the lack of detections suggests the presence of planetary companions with masses lower than $5M_J$, based on our derived mass detection limits. This is consistent with predictions of both hydrodynamical simulations and kinematical signatures on the disk, and allows us to set upper limits on the presence of massive planets in these young disks.

description: "To free Kentucky of slick roads" is the high goal toward which Kentucky has been striving since 1950's. A very capable fellow engineer used to say that there was more satisfaction in being able to take down a Slippery When Wet sign than in erecting one.  Considerable effort has been devoted to the development and adaptation of improved methods of skid resistance testing and to the standardization of testing devices (1, 2, 3, 4). Methods of tests have included the NCSA friction wheel (bicycle wheel), automobile deceleration, skewed-wheel (skewed front-wheels of an automobile), skidding automobile, and the skid-test trailer. The development and standardization of a trailer method of test in recent years represents significant progress in the measurement area.  From the outset of our skid resistance measurement program, evaluations of pavement design, construction and maintenance practices were of utmost concern. In fact, the first field tests -- made in 1953 -- resulted in changes of the design mix in the use at that time (5). Every type of pavement and sealing and deslicking treatment used in the state have been monitored and assessed as to their friction properties (1, 6, 7). Insights gained have been applied towards the development and refinements of wearing surfaces.  Skid resistance standards for maintenance and mix design purposes must be established if meaningful improvements in highway safety are to be realized. Arbitrary judgements as to minimum requirements will not suffice because the safety and economics involved are much to important to every highway user. Efforts to derive minimum skid resistance requirements in Kentucky were based on accident statistics. Critical values have been determined for rural, four-lane, controlled access roads (interstates and parkways) (8). Critical values for rural, two-lane roads (U.S. routes) are forthcoming.  Studies of pavement slipperiness have received renewed emphasis as a result of attention directed towards highway safety. Congress recognized the element of pavement skid resistance in the Highway Safety Act of 1966 and the resulting Highway Safety Program Standard !2, dated June 27, 1967. Most recently, Instructional Memorandum 21-2-73, dated July 19, 1973, stressed the importance of pavement skid resistance in providing safe highways. Kentucky has continued to progress in this vital area.

description: During the last years, low price products (e.g., private label) gain increasing market shares in the German meat market. Compared to other countries the share of branded meat from integrated production chains is very low and most fresh meat is sold unlabelled. This study analyzes the advantages of brands from an information economic perspective and emphasizes branding as an important quality assurance and signaling tool. As brand exte nsions offer the opportunity to introduce brands to new markets at much lower costs we examine the brand transfer from the poultry to the red meat market taking Wiesenhof, the German brand leader for chicken and poultry, as an example. We use conjoint and cluster analysis to calculate willingness to pay and market shares for different consumer segments. The results demonstrate, that branded meat reaches almost two third of market share while the low priced private label always gets the lowest proportions of consumer preferences. Given the choice, customers do not always prefer the cheapest offer but trust in branded meat even more. This market potential is actually not used to advantage. The overall total market share of meat brands lies below 5%.

description: We perform the quenched lattice QCD analysis on the nuclear force (baryon-baryon interactions). We employ $20^3\times 24$ lattice at $β=5.7$ ($a\simeq 0.19$ fm) with the standard gauge action and the Wilson quark action with the hopping parameters $κ=0.1600, 0.1625, 0.1650$, and generate about 200 gauge configurations. We measure the temporal correlators of the two-baryon system which consists of heavy-light-light quarks. We extract the inter-baryon force as a function of the relative distance $r$. We also evaluate the contribution to the nuclear force from each ``Feynman diagram'' such as the quark-exchange diagram individually, and single out the roles of Pauli-blocking effects or quark exchanges in the inter-baryon interactions.

An experimental and numerical study of novel nano-grained (γ+ α2)-TiAl/Al2O3 cermets.

In this paper, a microstructure-based finite element model for nano-grained (!+↵2)-TiAl/Al2O3 cermets is proposed based on a modified variational formulation of the Gurson model for an elastic-plastic porous material. In the modeling approach, the high volume fraction of alumina, variability in material characteristics, and microstructural features (e.g., inclusion size) are considered. Mechanical properties and microstructure inputs are derived from nanoindentation and microscopy analysis performed for this study, as well as using available information in the literature. Once developed, modeling results are validated against experimental quasi-static compressive stress-strain measurements using digital image correlation techniques. The validation is extended by comparing experimental observations and computational outputs of the ratio of the lateral to axial strain (as a measure of deformation), and reasonable agreement is found. Once the model is validated for an experimentally known condition, the effect of varying the mechanical properties (e.g., strain hardening parameters and elastic modulus) and microstructure variables (e.g., alumina volume fraction and porosity) on material responses are then explored. These results serve as a foundation for future microstructure optimization.

Subjects: subject: Transportation Engineering

description: Kentucky's first portland cement concrete shoulder project was conceived in 1970 and was inspired by the Portland Cement Association's issue Concrete Shoulders for Safe Modern Highways, Concrete Report, 1970, and FHWA's Informational Memorandum CMPB-17-70, Experimental Project for the Evaluation of Portland Cement Concrete Shoulders Adjacent to Concrete Mainline Pavement; Project Prospectus, National Experimental and Evaluation Program; May 12, 1970. It was expected that at least two states in each region would participate in the national program. A 3.442-mile section of US 31 W, between Radcliff and Tiptop, beginning at the intersection of US 60 and extending southward, scheduled for reconstruction, was chosen for implementation. The site is shown, in Figure 1. Bids were taken February 15, 1973, and project is now nearing completion. Construction cost will be nearly 6 million dollars.

How loud are echoes from exotic compact objects?

description: The first direct observations of gravitational waves (GWs) by the LIGO collaboration have motivated different tests of General Relativity (GR), including the search for extra pulses following the GR waveform for the coalescence of compact objects. The motivation for these searches comes from the alternative proposal that the final compact object could differ from a black hole (BH) by the lack of an event horizon and a central singularity. Such objects are expected in theories that, motivated by quantum gravity modifications, predict horizonless objects as the final stage of gravitational collapse. In such a hypothetical case, this exotic compact object (ECO) will present a (partially) reflective surface at $r_{\rm ECO}=r_{+}(1+ε)$, instead of an event horizon at $r_{+}$. For this class of objects, an in-falling wave will not be completely lost and will give rise to secondary pulses, to which recent literature refers as echoes. However, the largely unknown ECO reflectivity is determinant for the amplitude of the signal, and details also depend on the initial conditions of the progenitor compact binary. Here, for the first time, we obtain estimates for the detectability of the first echo, using a perturbative description for the inspiral-merger-ringdown waveform and a physically-motivated ECO reflectivity. Binaries with comparable masses will have a stronger first echo, improving the chances of detection. For a case like GW150914, the detection of the first echo will require a minimum ringdown signal-to-noise ratio (SNR) in the range $\sim 20-60$. The most optimistic scenario for echo detection could already be probed by LIGO in the next years. With the expected improvements in sensitivity we estimate one or two events per year to have the required SNR for the first echo detection during O4.
