description: Joint poster created by the H2020 (EU funded) projects SABYDOMA (GA no. 862296) and SbD4Nano (GA no. 862195) for the EuroNanoForum 2023 conference (11-13.06.2023, Lund, Sweden).

SABYDOMA's new methodology and technology addresses the existing challenges of Safety-by-Design (SbD) as a control tool for the production of safe(r) nanomaterials, i.e., addressing the SbD as a Control System Problem. The project outcome is a Demonstrator for online production of safe(r) nano: Coupling rapid screening with online production to enable safe(r) nano-manufacture and advance materials - New technology & modelling approaches and software for real world industrial applications.

SbD4Nano's mission is to create an e-infrastructure for performance testing & implementation of Safe-by-Design approaches in the nanotechnology supply chain. A major challenge for the global nanotechnology sector is the development of safe and functional engineered nanomaterials (ENMs) and nano-enabled products (NEPs). In order to minimise the risks to human and environmental health during the engineering of NEPs the goal of the SbD4Nano project is to create a novel e-infrastructure for the definition, performance testing and implementation of Safe-by-Design (SbD) approaches in the nanotechnology supply chains. SbD4Nano will overcome all the barriers to promote the implementation of SbD approaches in the nanotechnology industry, providing SMEs with a set of web-based applications and tools.

description: A stationary state replica analysis for a dual neural network model that interpolates between a fully recurrent symmetric attractor network and a strictly feed-forward layered network, studied by Coolen and Viana, is extended in this work to account for finite dilution of the recurrent Hebbian interactions between binary Ising units within each layer. Gradual dilution is found to suppress part of the phase transitions that arise from the competition between recurrent and feed-forward operation modes of the network. Despite that, a long chain of layers still exhibits a relatively good performance under finite dilution for a balanced ratio between inter-layer and intra-layer interactions.

description: Consumer-level hedonic models are estimated to determine factors affecting retail pork and beef meat cuts. Results indicate that brand premium and discount varies across private, national, and store brands and that brand premium varies across meat cuts carrying the same brand name. Product size discounts are linear for beef and nonlinear for pork, meat items on sale are significantly discounted to non-sale items, specialty stores typically will not garner higher prices than supermarket/grocery stores, and warehouse stores typically have premium prices relative to supermarket/grocery stores.
Above-room-temperature ferromagnetism in half-metallic Heusler compounds NiCrP, NiCrSe, NiCrTe and NiVAs: A first-principles study

description: We study the interatomic exchange interactions and Curie temperatures in half-metallic semi Heusler compounds NiCrZ (Z=P, Se, Te) and NiVAs. The study is performed within the framework of density functional theory. The calculation of exchange parameters is based on the frozen-magnon approach. It is shown that the exchange interactions in NiCrZ vary strongly depending on the Z constituent. The Curie temperature, Tc, is calculated within the mean field and random phase approximations. The difference between two estimations is related to the properties of the exchange interactions. The predicted Curie temperatures of all four systems are considerably higher than room temperature. The relation between the half-metallicity and the value of the Curie temperature is discussed. The combination of a high spin-polarization of charge carriers and a high Curie temperature makes these Heusler alloys interesting candidates for spintronics applications.

description: A Surface Dynamics Profilometer was acquired in December 1968. The SD Profilometer was designed to rapidly and accurately measure the profile of the surface over which it is driven. A Quarter-Car Simulator was obtained in 1970. The simulator, a special purpose analog computer, was designed to process road profiles measured with the SD Profilometer. This processing involves analog simulation of a simplified vehicle. Factors and variables associated with the devices and calibration and test procedures were investigated and standardized. The Automatic Roughness-Measuring System using an automobile (Kentucky interim standard method of test for roughness) was correlated with the SD Profllometer - QC Simulator system to permit continued assessment of pavements previously tested with the automobile.  Precision of the SD Profilometer and QC Simulator was demonstrated by repeated testing of several pavements. Pavements with the higher roughness indices exhibited about the same standard deviation as pavements with lower roughness indices. On a percentage basis, therefore, the measurement precision was better for a rougher pavement than for a smoother pavement. A single measurement was within three percent of the sample mean 95 percent of the time. The roughness index obtained by simulating the Bureau of Public Roads Roughometer within the QC Simulator system was selected as the best expression of road roughness.

description: Tourism represents one of the most important income sources for Italy. In recent years, apart from “traditional” destinations, tourism supply is widely changing in order to satisfy the customers “love for variety” and valorise marginal resources, then new formulas are emerging (e.g. agritourism). This work aims to elaborate and estimate an econometric model able to adequately explain the size of agritourists flows to Italy from main partner countries using the gravity model approach that has been broadly applied to the analysis of international flows. In this work, the “basic” model has been enlarged and improved with the introduction of other explicative variables. The results has allowed to confirm empirical validity of the gravity model in studying international flows of any nature. Furthermore, the estimated econometric model represents a useful analytical instrument to describe, and, eventually, predict demand of foreign visitors for agritourist vacations in Italy.
Feasibility study of a moving hand support for surgery on the beating heart
Creators: name: Trejos, Ana Luisa
Publisher: name: University of British Columbia
Year: 2009

description: A method for performing coronary bypass surgery on the beating heart is proposed, and entails the use of a heart-tracking support to move the hands of the surgeon in synchrony with the heart motion. This method eliminates the damaging effects associated with stopping or stabilizing the heart, while preserving the surgeon's dexterity and accuracy. First, a feasibility study was performed in order to compare the accuracy attained and the completion time required to perform accurate tasks on stable and moving targets, both with and without a motion tracking support. The results demonstrate that the negative effects of the target motion, namely, decreased accuracy and increased task completion time, are considerably reduced with the use of the support. The use of both monocular and stereo vision systems that provide a stable view of the work space was shown to limit the increase in task completion time; however, the accuracy was not improved due to the low resolution of the vision systems used. A solution to the design of the moving hand support consists of a three degree of freedom mechanism with prismatic joints. For this mechanism to accurately track the heart, it is necessary to measure the motion of the surgical area in real-time and to generate a suitable control strategy. After comparing several sensors that could be used to measure the heart motion, a mechanical sensor was designed and built. Despite the measurement error present in this particular prototype, it is believed that the design features of the sensor make it a suitable solution to the heart tracking problem. In order to address the problem of motion control, the moving support system was simulated using SIMULINK® and implemented on an experimental setup with PID and computed torque control. Furthermore, an additional control strategy is proposed that facilitates tracking of quasiperiodic, quantized inputs. Results show that it is possible for the mechanism to accurately follow the trajectory of the heart surface, since the maximum tracking error is approximately 0.15 mm.

description: Statewide survey of skid resistance continued in 1976 with testing of rural, major, collector roads (1985 Functional Classification). This included 5,074 miles (8,166 km) of state secondary roads and 788 miles (1,268 km) of rural secondary roads. About 17 percent of the secondary mileage and about 15 percent of the rural secondary mileage surveyed in 1976 may be considered slippery. A small percentage of both secondary (5.3 percent) and rural secondary (5.8 percent) roads had an average skid number below 26. These sections, in particular, should be flagged for deslicking.  Through 1976, 50 percent of the mileage of rural, state-maintained roads in Kentucky were surveyed. These roadways carried 93 percent of all traffic on rural, state-maintained roads.

description: We investigate the relativistic Fermi motion effect in the case of $J/ψ$ production in various hadron colliders. A light-cone wave function is adopted to represent the $J/ψ$ final state. The change in the confinement parameter which sets a scale for the size of the final state, allows one to see the effect in an explicit manner. While the effect has considerable influence on the fragmentation probabilities and the differential cross sections, the total cross sections are essentially left unchanged. such a feature is in agreement with the momentum sum rule which the fragmentation functions should satisfy.

description: This work introduces a new framework, named SAFFIRE, to automatically extract a dominant recurrent image pattern from a set of image samples. Such a pattern shall be used to eliminate pose variations between samples, which is a common requirement in many computer vision and machine learning tasks. The framework is specialized here in the context of a machine vision system for automated product inspection. Here, it is customary to ask the user for the identification of an anchor pattern, to be used by the automated system to normalize data before further processing. Yet, this is a very sensitive operation which is intrinsically subjective and requires high expertise. Hereto, SAFFIRE provides a unique and disruptive framework for unsupervised identification of an optimal anchor pattern in a way which is fully transparent to the user. SAFFIRE is thoroughly validated on several realistic case studies for a machine vision inspection pipeline.

description: The CAP reform and the recent EC communication aimed at preparing its Health Check emphasise the need for interventions locally based where agricultural policy integrates with a broader policy for rural areas growth. In this context, the paper investigates the possible different sets policy indicators affecting agricultural productivity at the regional level considering spatial heterogeneity by means of a Mixed Geographically Weighted Regression approach. The analysis is based on a set of policy sensitive indicators selected according to the key component of the CAP reform and referred to a sample of 164 EU-15 regions at NUTS2 level. The methodology adopted, new for the empirical literature on the topic, allows for a more accurate understanding of spatial relationship of the agricultural and socio-economic factors affecting agricultural productivity at the local level providing useful information for policy making.

Subjects: subject: Transportation Engineering

description: The purpose of this report was to analyze two urban intersections using conflict data, erratic maneuver data, and near-miss accident data and to recommend site improvements, if necessary. The two intersections selected were Euclid Avenue at Woodland Avenue and New Circle Road at Woodhill Drive in Lexington. Data were taken using 11-hour observation periods.  Proposed improvements for the site on Euclid Avenue included adding dual left-tum lanes and three-phase signals or an extended multi-turn lane. At the New Circle site, a longer, more gradual right-turn lane and repositioning some of the signing are recommended. The conflict data recorded were found to be very useful in identifying the specific causes of the problems.
Wind Development in Minnesota: Policy and Economics

Subjects: Resource /Energy Economics and Policy

description: The growth of wind power as an aspect of Minnesota’s portfolio of electricity has been propelled to its current level by policy initiatives at both the federal and state levels. Existing statutes establish requirements for further expansion of wind energy in this state in the years to come. Locally, production economics exert their influence as wind speed and duration are translated to capacity factor, which reveals the amount of power that can be generated at a particular site. After the flow resource is thus quantified, comes the calculus of economic viability. This consists of determining the capital and operating costs and eligibility for loans and grants as well as the negotiations of wind rights, easements, and power purchase agreements. To date, policy initiatives have been directed toward the production, or generation side of this variable flow resource. Entrepreneurs and lawyers have become more skillful at organizing business forms that can effectively bring together partners capable of utilizing the substantial tax benefits available through the federal Production Tax Credit (PTC) as well as attractive state-sponsored incentives and tariffs offered by utilities. The variable nature of electrical power capacity from wind has been problematic for utilities, which try to meet the variable loads required by the summed demand of their customers. In Minnesota, peak power demands occur in summer months when wind power is the lowest. In addition to seasonal demands, daily and weekly patterns must be accommodated by utilities serving the markets for electricity. By developing and using an investment model, it is possible to understand investor motivations driving the growth of wind energy in this state and the country. Net present values (NPV) and internal rates of return (IRR) are calculated over the life of power production projects conforming to various conditions such as wind capacity factor, the federal Production Tax Credit (PTC), state incentive plans for community-based energy providers, federal grant and loan programs, as well as emerging opportunities to sell “green tags” for renewable power generation. The numerous incentives provided for windpower development on the generation side highlight the difficulties of providing sufficient transmission capacity for to carry this power from the often remote areas where generated to load centers. Equivalent incentives deployed with similar imagination are needed to enhance investment in a transmission system capable of carrying increasing volumes of wind and other renewable sources of electricity.

description: Der Aufsatz gibt einen Überblick über die literarische Produktion in Rheinsberg von der Zeit des Kronprinzen Friedrich (1736–1740) bis in die Gegenwart. Friedrich schrieb im Turmzimmer des Schlosses 1739 seinen Antimachiavell. Bereits im frühen 19. Jahrhundert setzte die Literarisierung der Kronprinzenzeit ein. Theodor Fontane mit seinen Wanderungen durch die Mark Brandenburg, deren erstes Kapitel in Rheinsberg einsetzt (1862), erweiterte den Blick auf den Prinzen Heinrich. Dem folgte der Engländer Andrew Hamilton mit seinem Rheinsberg-Buch (dt. 1882). Im 20. Jahrhundert prägte Kurt Tucholsky mit seinem Rheinsberg. Ein Bilderbuch für Verliebte (1912) das Bild einer heiteren Idylle. Sebastian Haffner und Annemarie Schwarzenbach setzten Anfang der 1930er-Jahre jeweils eigene Akzente. Seit 1995 sind es die Rheinsberger Stadtschreiber (u. a. Barbara Köhler, Annett Gröschner und Wiglaf Droste), die ein facettenreiches literarisches Bild von Rheinsberg liefern.

description: In order to study the possibility of acoustic detection of ultra-high energy neutrinos in water, our group is planning to deploy and operate an array of acoustic sensors using the ANTARES Neutrino telescope in the Mediterranean Sea. Therefore, acoustic sensor hardware has to be developed which is both capable of operation under the hostile conditions of the deep sea and at the same time provides the high sensitivity necessary to detect the weak pressure signals resulting from the neutrino's interaction in water. In this paper, two different approaches to building such sensors, as well as performance studies in the laboratory and in situ, are presented.

description: The benefit transfer refers to the use and adaptation of benefit measures obtained for a specific site (study site), to assess the benefits in another site (policy site), for which no original valuation is possible. Relying on relatively simplicity of application, and allowing saving time and money for the implementation, it represents a ‘second best’ solution and a valid alternative to the disregarding environmental economic values. The literature broadly agrees in considering two main approaches to benefit transfer: the transfer of a value or of a benefit function. The choice of the more suitable approach relies on the number of potential primary studies, the similarity degree between the study and the policy sites, on the purposes of the assessment and on the accuracy required. In this paper, the phases of conducting benefit transfer are outlined, highlighting the conditions for the transfer process and its limitations. Finally, the possible transfer errors related to incorrect transfer are reported and discussed.

We also discuss the relation between brane tilings and the dual Calabi-Yau cones realized as the moduli spaces of gauge theories. Two types of flavor D5-branes in brane tilings and corresponding superpotentials of fundamental quark fields are proposed, and it is shown that the massless loci of these quarks in the moduli space correctly reproduce the worldvolume of flavor D7-branes in the Calabi-Yau cone dual to the fivebrane system.

description: The serendipitous discovery of an unidentified extended TeVgamma-ray source close to the galactic plane named HESS J1303-631 at a significance of 21 standard deviations is reported. The observations were performed between February and June 2004 with the H.E.S.S. stereoscopic system of Cherenkov telescopes in Namibia. HESS J1303-631 was discovered roughly 0.6 deg north of the binary system PSR B1259-63/SS 2883, the target object of the initial observation campaign which was also detected at TeV energies in the same field of view. HESS J1303-631 is extended with a width of an assumed intrinsic Gaussian emission profile of sigma = (0.16 +- 0.02) deg and the integral flux above 380 GeV is compatible with constant emission over the entire observational period of (17 +- 3)% of the Crab Nebula flux. The measured energy spectrum can be described by a power-law dN/dE ~ E^-Gamma with a photon index of Gamma = 2.44 +- 0.05_stat +- 0.2_syst. Up to now, no counterpart at other wavelengths is identified. Various possible TeV production scenarios are discussed.

description: We analyze a data set comprising 370 GW band structures composed of 61716 quasiparticle (QP) energies of two-dimensional (2D) materials spanning 14 crystal structures and 52 elements. The data results from PAW plane wave based one-shot G$_0$W$_0$@PBE calculations with full frequency integration. We investigate the distribution of key quantities like the QP self-energy corrections and renormalization factor $Z$ and explore their dependence on chemical composition and magnetic state. The linear QP approximation is identified as a significant error source and propose schemes for controlling and drastically reducing this error at low computational cost. We analyze the reliability of the $1/N_\text{PW}$ basis set extrapolation and find that is well-founded with narrow distributions of $r^2$ peaked very close to 1. Finally, we explore the validity of the scissors operator approximation concluding that it is generally not valid for reasonable error tolerances. Our work represents a step towards the development of automatized workflows for high-throughput G$_0$W$_0$ band structure calculations for solids.

description: When an amorphous solid is deformed cyclically, it may reach a steady state in which the paths of constituent particles trace out closed loops that repeat in each driving cycle. A remarkable variant has been noticed in simulations where the period of particle motions is a multiple of the period of driving, but the reasons for this behavior have remained unclear. Motivated by mesoscopic features of displacement fields in experiments on jammed solids, we propose and analyze a simple model of interacting soft spots -- locations where particles rearrange under stress and that resemble two-level systems with hysteresis. We show that multiperiodic behavior can arise among just three or more soft spots that interact with each other, but in all cases it requires frustrated interactions, illuminating this otherwise elusive type of interaction. We suggest directions for seeking this signature of frustration in experiments and for achieving it in designed systems.

description: Current projections indicate that by 2025, water scarcity will affect over one quarter of the world’s population. This suggests that the need to manage water more efficiently will become more pressing during the next few years as the demand for water increases along with the expansion of economies and their populations. This paper investigates the economic impacts of efficient intraregional and/or inter-regional water reallocation, and examines their corresponding economic gains. A Ramsey-type growth model of a small, open, competitive economy is fitted to year 2000 Chinese data andthe empirical model is used to perform policy experiments. Within region water reallocation increases per-capita Chinese GDP by about 1.5% per year over the period 2000-2060. The aggregate potential welfare gain due to this reallocation is 1002.51 billion RMB. Transferring water from southern to northern China via the South-North Water Transfer Project, on average, has a smaller impact on per-capita GDP over the period 2000-2060, with an aggregate welfare gain of 557.23 billion RMB.

description: In this work we derive general quantum phenomenological equations of gravitational dynamics and analyse its features. The derivation uses the formalism developed in thermodynamics of spacetime and introduces low energy quantum gravity modifications to it. Quantum gravity effects are considered via modification of Bekenstein entropy by an extra logarithmic term in the area. This modification is predicted by several approaches to quantum gravity, including loop quantum gravity, string theory, AdS/CFT correspondence and generalised uncertainty principle phenomenology, giving our result a general character. The derived equations generalise classical equations of motion of unimodular gravity, instead of the ones of general relativity, and they contain at most second derivatives of the metric. We provide two independent derivations of the equations based on thermodynamics of local causal diamonds. First one uses Jacobson's maximal vacuum entanglement hypothesis, the second one Clausius entropy flux. Furthermore, we consider questions of diffeomorphism and local Lorentz invariance of the resulting dynamics and discuss its application to a simple cosmological model, finding a resolution of the classical singularity.

description: ASAS is a long term project to monitor bright variable stars over the whole sky. It has discovered 50,122 variables brighter than V < 14 mag south of declination +28 degrees, and among them 11,099 eclipsing binaries. We present a preliminary analysis of 5,384 contact, 2,957 semi-detached, and 2,758 detached systems. The statistics of the distribution provides a qualitative confirmation of decades old idea of Flannery and Lucy that W UMa type binaries evolve through a series of relaxation oscillations: ASAS finds comparable number of contact and semidetached systems. The most surprising result is a very small number of detached eclipsing binaries with periods P < 1 day, the systems believed to be the progenitors of W UMa stars. As many (perhaps all) contact binaries have companions, there is a possibility that some were formed in a Kozai cycle, as suggested by Eggleton and his associates.

description: Should I have a beef herd on my farm? If I should, how large should it be? These are questions currently being asked by many farmers. Each farm is a unique business with individual resource and management situations so that no pat answer can be given. However, given the proper information to which farmers can relate their situation, they can provide their own answers. This bulletin provides such information.

description: One of the main challenges in times of sanitary emergency is to quickly develop computer aided diagnosis systems with a limited number of available samples due to the novelty, complexity of the case and the urgency of its implementation. This is the case during the current pandemic of COVID-19. This pathogen primarily infects the respiratory system of the afflicted, resulting in pneumonia and in a severe case of acute respiratory distress syndrome. This results in the formation of different pathological structures in the lungs that can be detected by the use of chest X-rays. Due to the overload of the health services, portable X-ray devices are recommended during the pandemic, preventing the spread of the disease. However, these devices entail different complications (such as capture quality) that, together with the subjectivity of the clinician, make the diagnostic process more difficult and suggest the necessity for computer-aided diagnosis methodologies despite the scarcity of samples available to do so. To solve this problem, we propose a methodology that allows to adapt the knowledge from a well-known domain with a high number of samples to a new domain with a significantly reduced number and greater complexity. We took advantage of a pre-trained segmentation model from brain magnetic resonance imaging of a unrelated pathology and performed two stages of knowledge transfer to obtain a robust system able to segment lung regions from portable X-ray devices despite the scarcity of samples and lesser quality. This way, our methodology obtained a satisfactory accuracy of $0.9761 \pm 0.0100$ for patients with COVID-19, $0.9801 \pm 0.0104$ for normal patients and $0.9769 \pm 0.0111$ for patients with pulmonary diseases with similar characteristics as COVID-19 (such as pneumonia) but not genuine COVID-19.

Anti-Truncation of Disks in Early-Type Barred Galaxies

description: The disks of spiral galaxies are commonly thought to be truncated: the radial surface brightness profile steepens sharply beyond a certain radius (3--5 inner-disk scale lengths). Here we present the radial brightness profiles of a number of barred S0--Sb galaxies with the opposite behavior: their outer profiles are distinctly shallower in slope than the main disk profile. We term these "anti-truncations"; they are found in at least 25% of a larger sample of barred S0--Sb galaxies. There are two distinct types of anti-truncations. About one-third show a fairly gradual transition and outer isophotes which are progressively rounder than the main disk isophotes, suggestive of a disk embedded within a more spheroidal outer zone -- either the outer extent of the bulge or a separate stellar halo. But the majority of the profiles have rather sharp surface-brightness transitions to the shallower, outer exponential profile and, crucially, outer isophotes which are not significantly rounder than the main disk; in the Sab--Sb galaxies, the outer isophotes include visible spiral arms. This suggests that the outer light is still part of the disk. A subset of these profiles are in galaxies with asymmetric outer isophotes (lopsided or one-armed spirals), suggesting that interactions may be responsible for at least some of the disklike anti-truncations.

description: Minimum Jerk trajectories have been long thought to be the reference trajectories for human movements due to their impressive similarity with human movements. Nevertheless, minimum jerk trajectories are not the only choice for $C^\infty$ (i.e., smooth) functions. For example, harmonic trajectories are smooth functions that can be superimposed to describe the evolution of physical systems. This paper analyses the possibility that motor control plans using harmonic trajectories, will be experimentally observed to have a minimum jerk likeness due to control signals being transported through the Central Nervous System (CNS) and muscle-skeletal system. We tested our theory on a 3-link arm simulation using a recently developed planner that we reformulated into a motor control architecture, inspired by the passive motion paradigm. The arm performed 100 movements, reaching for each target defined by the clock experiment. We analysed the shape of the trajectory planned in the CNS and executed in the physical simulator. We observed that even under ideal conditions (i.e., absence of delays and noise) the executed trajectories are similar to a minimum jerk trajectory; thus, supporting the thesis that the human brain might plan harmonic trajectories.

description: We derive an expansion of the functional renormalization (fRG) equations that treats the frequency and momentum dependencies of the vertices in a systematic manner. The scheme extends the channel-decomposed fRG equations to the frequency domain and reformulates them as a series of linear integral equations in the particle-particle, particle-hole and particle-hole exchange channels. We show that the linearity of the equations offers numerous computational advantages and leads to converged, stable solutions for a variety of Hamiltonians. As the expansion is in the coupling between channels, the truncations that are necessary to making the scheme computationally viable still lead to equations that treat contributions from all channels equally. As a first benchmark we apply the two-loop fRG equations to the single impurity Anderson model. We consider the sources of error within the fRG, the computational cost associated with each, and how the choice of regulator affects the flow of the fRG. We then use the optimal truncation scheme to study the Extended Hubbard Hamiltonian in one and two dimensions. We find that in many cases of interest the fRG flow converges to a stable vertex and self-energy from which we can extract the various correlation functions and susceptibilities of interest.
Passive States for Essential Observers

description: The aim of this note is to present a unified approach to the results given in \cite{bb99} and \cite{bs04} which also covers examples of models not presented in these two papers (e.g. $d$-dimensional Minkowski space-time for $d\geq 3$). Assuming that a state is passive for an observer travelling along certain (essential) worldlines, we show that this state is invariant under the isometry group, is a KMS-state for the observer at a temperature uniquely determined by the structure constants of the Lie algebra involved and fulfills (a variant of) the Reeh-Schlieder property. Also the modular objects associated to such a state and the observable algebra of an observer are computed and a version of weak locality is examined.
