description: The renaturation of river and coastal embankments needs to include ecological aspects and the stability of shorelines. The impact of waves caused by heavy ship traffic could lead to erosion processes and to the degradation of soils along the coast. To evaluate the stability of shorelines it is necessary to quantify soil stability parameters as well as stress impacts of the waves. Therefore, stress measurements of ship waves were carried out at Kiel Canal. In order to determine the three main stresses (σ1, σ2, and σ3), the averaged mean stress (MNS), and the oc-tahedral shear stress a new developed stress state transducer system was firstly tested. This newly constructed system (Mudflat-SST) is equipped with an exchangeable battery for long time measurements and waterproof, which allows measurements in water and saturated soils. The sensors heads were placed above and below the middle water level for determining the effect of waves and a potential drag effect. During two periods, different types of ships were measured such as container vessel, cargo ship, ferry, and catamaran. Maximum stress impacts of 3 kPa were determined. The results show different kind of waves regarding their period or expression for the different ship types. In order to quantify the maximum stress impact of breaking waves, further research is needed to optimize sensor head´s location in the water and saturated soil.

description: Due to the absence of direct measurement, the magnetic field in the solar corona is usually extrapolated from the photosphere in numerical way. At the moment, the nonlinear force-free field (NLFFF) model dominates the physical models for field extrapolation in the low corona. Recently we have developed a new NLFFF model with MHD relaxation to reconstruct the coronal magnetic field. This method is based on CESE--MHD model with the conservation-element/solution-element (CESE) spacetime scheme. In this paper, we report the application of the CESE--MHD--NLFFF code to \SDO/HMI data with magnetograms sampled for two active regions (ARs), NOAA AR 11158 and 11283, both of which were very non-potential, producing X-class flares and eruptions. The raw magnetograms are preprocessed to remove the force and then inputted into the extrapolation code. Qualitative comparison of the results with the \SDO/AIA images shows that our code can reconstruct magnetic field lines resembling the EUV-observed coronal loops. Most important structures of the active regions are reproduced excellently, like the highly-sheared field lines that suspend filaments in AR 11158 and twisted flux rope which corresponds to a sigmoid in AR 11283. Quantitative assess of the results shows that the force-free constraint is fulfilled very well in the strong-field regions but apparently not that well in the weak-field regions because of data noise and numerical errors in the small currents.

description: Recently a debate has arisen over which of the two distinct parts of the Fermi surface of Sr2RuO4, is the active part for the chiral p-wave superconductivity. Early theories proposed p-wave pairing on the two dimensional gamma-band, while a recent proposal focuses on the one dimensional (alpha,beta) bands whose nesting pockets are the source of the strong incommensurate spin density wave (SDW) fluctuations. We apply a renormalization group theory to study quasi-one dimensional repulsive Hubbard chains and explain the form of SDW fluctuations, reconciling the absence of long range order with their nesting Fermi surface. The mutual exclusion of p-wave pairing and SDW fluctuations in repulsive Hubbard chains favors the assignment of the two dimensional gamma-band as the source of p-wave pairing.

description: We revise the conditions for the physical viability of a cosmological model in which dark matter has bulk viscosity and also interacts with dark energy. We have also included radiation and baryonic matter components; all matter components are represented by perfect fluids, except the dark matter, that is treated as an imperfect fluid. We impose upon the model the condition of a complete cosmological dynamics that results in an either null or negative bulk viscosity, but the latter also disagrees with the Local Second Law of Thermodynamics. The model is also compared with cosmological observations at different redshifts: type Ia supernova, the shift parameter of CMB, the acoustic peak of BAO, and the Hubble parameter H(z). In general, observations consistently point out to a negative value of the bulk viscous coefficient, and in overall the fitting procedure shows no preference for the model over the standard LCDM model.

description: Numerical relativity simulations of compact binaries with the Z4c and BSSNOK formulations are compared. The Z4c formulation is advantageous in every case considered. In simulations of non-vacuum spacetimes the constraint violations due to truncation errors are between one and three orders of magnitude lower in the Z4c evolutions. Improvements are also found in the accuracy of the computed gravitational radiation. For equal-mass irrotational binary neutron star evolutions we find that the absolute errors in phase and amplitude of the waveforms can be up to a factor of four smaller. The quality of the Z4c numerical data is also demonstrated by a remarkably accurate computation of the ADM mass from surface integrals. For equal-mass non-spinning binary puncture black hole evolutions we find that the absolute errors in phase and amplitude of the waveforms can be up to a factor of two smaller. In the same evolutions we find that away from the punctures the Hamiltonian constraint violation is reduced by between one and two orders of magnitude. Furthermore, the utility of gravitational radiation controlling, constraint preserving boundary conditions for the Z4c formulation is demonstrated. The evolution of spacetimes containing a single compact object confirm earlier results in spherical symmetry. The boundary conditions avoid spurious and non-convergent effects present in high resolution runs with either formulation with a more naive boundary treatment. We conclude that Z4c is preferable to BSSNOK for the numerical solution of the 3+1 Einstein equations with the puncture gauge.

description: Acquiring lexical information is a complex problem, typically approached by relying on a number of contexts to contribute information for classification. One of the first issues to address in this domain is the determination of such contexts. The work presented here proposes the use of automatically obtained FORMAL role descriptors as features used to draw nouns from the same lexical semantic class together in an unsupervised clustering task. We have dealt with three lexical semantic classes (HUMAN, LOCATION and EVENT) in English. The results obtained show that it is possible to discriminate between elements from different lexical semantic classes using only FORMAL role information, hence validating our initial hypothesis. Also, iterating our method accurately accounts for fine-grained distinctions within lexical classes, namely distinctions involving ambiguous expressions. Moreover, a filtering and bootstrapping strategy employed in extracting FORMAL role descriptors proved to minimize effects of sparse data and noise in our task.

Der Sensor konnte in das bestehende Monitoring-System eingebunden werden. Die Auswertung erfolgte mit Analysemethoden der Signaltheorie. Bisher kam zur Frequenzanalyse meist nur die konventionelle Fourier-Transformation zur Anwendung. Mit der Wavelet-Transformation und der Kurzzeit-Fourier-Transformation stehen aber Methoden zur Verfügung, die auch die zeitlichen Veränderungen der Schwingungsfrequenzen aufzeigen. Die berechneten Werte stimmen mit Dauer und Zeitpunkt der einzelnen Glockenschwingungen überein. Die Auswertung der Zeitreihen ergab für alle eingesetzten Sensortypen vergleichbare Amplituden und Frequenzen. Darüber hinaus wurden weitere Objekte messtechnische untersucht.

description: In the context of high quality food, such as meals in a gastronomic restaurant, classical approaches using liking levels hardly differentiate recipes as products are all rated excellent. More, recipes are often complex, with many stimuli contributing the overall judgment: the visual dressing of the plate, the flavour and texture of each component, e.g. meat, vegetable 1, vegetable 2, sauce, starch…
The objective of this work is to define a way to measure consumer opinion of complex dishes allowing to compare recipes and draw conclusions for possible improvements.
The selected method is based on spontaneous language as it is hypothesised that emotions would be more relevant than liking scores to reach a better discriminability. Consumers are asked to give 3 words to describe their experience of the food. Then the R3M algorithm takes into account the language structure: the meaning but also the world nature (grammatical, logic, valence...) and the verbalisation context. Consumers are also asked to rate their liking of the food and give positive and negative reasons explaining the given scores. Regular clients of the restaurant participated in the study (n=120). Four dishes of two menus were evaluated : Menu Créativité and Menu Bien-être.
In a general perspective, the two methods gave consistent results and allow to show the menu Créativité was slighty more preferred than the other one.
In a detailed analysis, the spontaneous language approach allowed to identify associated emotions that were not verbalised in the liking measures. More specifically, it also allowed to identify some sensory characteristics to be adjusted for better satisfaction.
The spontaneous verbalization helped to go beyond rational diagnosis, bringing emotional dimensions crucial for this high-end culinary universe, such as surprise, aesthetics and originality of the dishes.

description: The effective potential of the order parameter for confinement is calculated for SU(N) Yang--Mills theory in the Hamiltonian approach. Compactifying one spatial dimension and using a background gauge fixing, this potential is obtained within a variational approach by minimizing the energy density for given background field. In this formulation the inverse length of the compactified dimension represents the temperature. Using Gaussian trial wave functionals we establish an analytic relation between the propagators in the background gauge at finite temperature and the corresponding zero-temperature propagators in Coulomb gauge. In the simplest truncation, neglecting the ghost and using the ultraviolet form of the gluon energy, we recover the Weiss potential. We explicitly show that the omission of the ghost drastically increases the transition temperature. From the full non-perturbative potential (with the ghost included) we extract a critical temperature of the deconfinement phase transition of 269 MeV for the gauge group SU(2) and 283 MeV for SU(3).

description: Die Unterzeichnung der „Berliner Erklärung über offenen Zugang zu wissenschaftlichem Wissen“ im Herbst 2003 war für die DFG Anlass, sich verstärkt für die Bereitstellung freier, nachnutzbarer Publikationen und Daten zu engagieren. Dieses Engagement findet seinen Ausdruck nicht nur in einschlägigen Förderrichtlinien und Förderprogrammen, sondern auch in den wissenschaftspolitischen Aktivitäten der DFG. Der Beitrag zeigt auf, wie sich die konkreten Formen der Unterstützung von Open Access und Open Data durch die DFG aus einigen wenigen Prinzipien erklären lassen, die für das Förderhandeln der DFG grundlegend sind. Nach einer kurzen Erläuterung der wesentlichen Förderrichtlinien werden sowohl Förderprogramme vorgestellt, die wissenschaftlichen Communities die Möglichkeit bieten, aus eigener Initiative für sie relevante Open Access Entwicklungen anzustoßen und umzusetzen, als auch solche Förderinstrumente, denen eine konkret strukturbildende Zielsetzung inhärent ist. Damit die Transformation vom Subskriptionsmodell hin zu einer durch Open Access geprägten Wissenschaftskommunikation gelingen kann, sind auch wissenschaftliche Einrichtungen sowie Forscherinnen und Forscher dazu aufgerufen, die finanziellen, technischen und rechtlichen Aspekte zu beachten und zu gestalten, die für die offene Bereitstellung von Forschungsergebnissen unerlässlich sind.
description: After the DFG signed the „Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities“, the organisation started to strengthen its commitment for the open sharing of re-usable publications and data. This is not only proven by dedicated funding guidelines and funding programmes, yet also by DFG’s commitment in science policy. The article shows how the concrete forms of DFG’s support for open access and open data can easily be derived from a few principles which are fundamental to all of DFG activities. The paper depicts the relevant funding guidelines and explains which funding instruments offer the opportunity to a scientific community to develop and deploy open-access-initiatives which specifically benefit the researchers. Furthermore, some funding programmes which target the establishment of specific open access infrastructures are presented. The transformation from the subscription model to a science communication which is characterized by open access can only succeed, however, if research institutions as well as researchers and scholars themselves consider the financial, technical and legal challenges and design the implementation in a way that is necessary for the open provision of research results

Diese monatlichen Lösungen wurden mittels eigener GRACE-SIGMA Software in zwei Prozessierunsschritten unter Verwendung von Variationsgleichungen berechnet. Im ersten Schritt werden Satellitenbögen und die Zustands- und Parametersensitivitätsmatrizen dynamisch mittels eines Gauss-Jackson-Integrators modelliert. Hierfür verwenden wir Satellitenbögen mit einer Länge von 3 Stunden. In diesem Schritt werden Zustandsvektoren und Akzelerometer-Bias-Parameter mit GRACE L1B reduziert-dynamischen Positionen als Hauptbeobachtungen bestimmt. Im zweiten Schritt werden Normalgleichungen akkumuliert und normalisierte sphärisch-harmonische Schwerefeldkoeffizienten bis Grad und Ordnung 80 zusammen mit empirischen Parametern und Parametern aus Schritt 1 bestimmt. Hierfür werden KBRR-Messungen als Hauptbeobachtungen verwendet. Zudem werden reduziert-dynamische Positionen eingeführt, um die Koeffizienten niederen Grades zu bestimmen. Die Grad-Standardabweichungen unserer Lösungen sind vergleichbar mit den korrespondierende Werten der drei Analysezentren CSR, GFZ und JPL. Im Folgenden werden Prozessierungsdetails präsentiert und unsere Lösungen den Referenzlösungen gegenübergestellt. Die neuen Zeitreihen mit dem Namen LUH-GRACE2018 sind auf den Webseiten des IfE und ICGEM zu finden.

description: This study aims to assess the vegetation cover and topographic humidity index of the Trueno microbasin and the Brisas site of the Bolivar canton (Manabi, Ecuador) so it can be used as a tool for policies decision. Starting from a quantitative approach and applying the hypothetical-deductive method; the following phases were established: i) determination of the Hydrological Protection Index (HPI), in this case plots made up of "three radiated transects 50 m long, located at 120° from each other; and, ii) establishment of the topographic humidity index, as a result of the treatment of the information in QGIS 3.30.1 through a Digital Elevation Model (DEM). The primary findings demonstrate that the light forests achieved an HPI per unit of vegetation (HPI-UV) of 0.95, while the dense forests attained a maximum of 1. On the other hand, the whole annual grasslands scored 0.64, while the degraded annual grasslands scored 0.32, the lowest possible score. When paired with other criteria, the ITH's values, which carry out a classification of the soil into five categories, range from 0 to 19, indicating a close association with the microbasin's water network. These assessments serve as a management tool for the creation and implementation of successful policies that ensure the stability of these ecosystems. Keywords: hydrological protection, microbasin, topographic humidity.

description: The prompt fission neutron spectra for neutron-induced fission of 233U for low energy neutrons (below 6 MeV) are calculated using the nuclear evaporation theory with a semi-empirical method, in which the partition of the total excitation energy between the fission fragments for the nth+233U fission reactions are determined with the available experimental and evaluation data. The calculated prompt fission neutron spectra agree well with the experimental data. The proportions of high- energy outgoing neutrons of prompt fission neutron spectrum versus incident neutron energies are investigated with the theoretical spectra, and the results are consistent with the systematics. We conclude that the semi-empirical method is sound, and it could be a useful tool for prompt fission neutron spectra evaluation.

description: Der Artikel vermittelt einen kurzen Überblick darüber, welche archäologischen ‚Primärdaten’ aktuell, also im Jahr 2014, als Open Data im deutschsprachigen Raum verfügbar sind und stellt das Projekt IANUS vor, das sich die langfristige Archivierung und Bereitstellung dieser Daten zum Ziel gesetzt hat. In den meisten deutschen altertumswissenschaftlichen Projekten werden die Ergebnisse und Materialvorlagen als statische analoge oder digitale Publikationen vorgelegt. Die zugehörigen Forschungsdaten bleiben dagegen meistens verschlossen und sind einer weiteren Nutzung entzogen, obwohl diese Anforderung immer häufiger formuliert wird. Es wird daher untersucht, welche Angebote und Datenbestände derzeit tatsächlich in verschiedenen digitalen Archiven, Onlineportalen und Verlagen frei zugänglich sind. Das resultierende Bild wird mit der Situation in anderen Fachdisziplinen und im Ausland verglichen, um die technischen Möglichkeiten und wissenschaftlichen Potentiale einer konsequenten Open Data-Strategie aufzuzeigen. Im zweiten Teil wird das von der DFG geförderte Projekt IANUS vorgestellt, mit dem ein nationales Forschungsdatenzentrum für die Archäologien und Altertumswissenschaften in Deutschland aufgebaut wird. Das Ziel ist es, eine langfristige, fachspezifische Infrastruktur zu betreiben, die sowohl eine professionelle Archivierung als auch einen dauerhaften Zugriff auf Daten gewährleistet. Neben knappen Angaben zum Stand des Projektes werden auch potentielle Hürden bei der Verbreitung der Open Access-Idee in den Altertumswissenschaften in Deutschland thematisiert.
description: This article will discuss the possibilities of finding and re-using primary research data from archaeological disciplines in Germany and will introduce the future data research center IANUS, that will archive and provide these kind of data. Most projects, at least in the field of ancient studies in Germany, publish their final results and catalogues as static data either in printed or digital format. However, the related ‘raw data’ remains in most cases closed and inaccessible for third parties although this demand is formulated with increasing pressure. Thus the authors examine how much data is indeed freely available and reusable in different digital archives, online-portals and data-publications. Comparisons with other disciplines and practices in other countries will contrast the results. The second part will describe the DFG funded project IANUS which aims to establish a national, domain specific technical infrastructure for the professional archiving and free dissemination of raw data. The article will present the current status of the project, its future services and the obstacles in promoting the ideas of open access and reuse of data in the field of ancient studies in Germany.

description: It is argued that the stress caused by vortex cores in the mixed state of superconductors may result in a field dependent contribution to the free energy and magnetization of measurable levels. For sufficiently strong stress dependence of the critical temperature, $\partial T_c/\partial p$, this contribution may result in the so-called "second peak" in the field dependence of the reversible magnetization, the effect often masked by vortex pinning and creep.

description: Pumped municipal solid waste landfill leachate samples (7 cells from a site in Nebraska, 4 cells from a site in Illinois) have been analyzed for 62 elements using Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). A procedure for complete dissolution of solids in the leachate was developed. Complete dissolution aims to reduce material loss in filtration by eliminating the need for filtration, and frees materials entrapped in undissolved solids. The procedure uses centrifugation to separate solid phase matter from the raw sample to maximize the effect of acid, and uses Chloric, Nitric, Fluoric, and Boric acids with microwave digestion to achieve full dissolution. The dissolved solid fraction precipitates yttrium fluoride and some other metals due to over-solubility concentrations; the precipitate is recovered and redissolved for analysis. Platinum, (Post-) Transition, and Lanthanide group metals were positively detected in the landfill leachate. Individual metals from these groups were detected in either/both aqueous or/and solid phases: solid phase metals are usually at least one magnitude of concentration greater than liquid phase metals, unless the solid phase produced no detection of the metal where the liquid phase did. Noteworthy results are: in the solid phase; Al was quantified from 10 to 103 𝜇g/g of solid mass; Sc, Cr, Ti, and Cu were quantified in the solid phase from 1 to 50 𝜇g/g of solid mass; Zr and Eu were quantified from .5 to ~8 𝜇g/g of solid mass. In the liquid phase: Ti, Cr, Li, Cu, As, and Zr were quantified mostly between 10-2 to 10-1 𝜇g/g of liquid mass, but occasionally reach out of those bounds; Al, Sc, Pt, Co, and V were quantified mostly from 10-3 to 10-2 𝜇g/g of solid mass. Solid phase metals were positively detected with a minimum Limit of Detection (LOD) usually around 10-1 𝜇g/g of solid mass, including: In, Ge, Pb, Ru, Sb, Ta, Hf, Bi, Yb, La, Ti, Pd, Lu, Dy, and Tb. Liquid phase metals were positively detected with a minimum LOD usually around 10-5 𝜇g/g of liquid mass, including: Tm, Ge, Au, Pb, Sb, Ta, Hf, Sm, Nb, Ho, Ga, Bi, Yb, Pd, Er, and Cd.

description: In recent work, robust mixture modelling approaches using skewed distributions have been explored to accommodate asymmetric data. We introduce parsimony by developing skew-t and skew-normal analogues of the popular GPCM family that employ an eigenvalue decomposition of a positive-semidefinite matrix. The methods developed in this paper are compared to existing models in both an unsupervised and semi-supervised classification framework. Parameter estimation is carried out using the expectation-maximization algorithm and models are selected using the Bayesian information criterion. The efficacy of these extensions is illustrated on simulated and benchmark clustering data sets.

description: In the paper, the authors discover the best constants $α_{1}$, $α_{2}$, $β_{1}$, and $β_{2}$ for the double inequalities $$ α_{1}\bar{C}(a,b)+(1-α_{1}) A(a,b)< T(a,b) 0$ with $a\ne b$, where $$ \bar{C}(a,b)=\frac{2(a^{2}+ab+b^{2})}{3(a+b)},\quad A(a,b)=\frac{a+b}2, $$ and $$ T(a,b)=\frac{2}π\int_{0}^{π/{2}}\sqrt{a^2{\cos^2θ}+b^2{\sin^2θ}}\,\tdθ$$ are respectively the centroidal, arithmetic, and Toader means of two positive numbers $a$ and $b$. As an application of the above inequalities, the authors also find some new bounds for the complete elliptic integral of the second kind.

title: “Cross-Writing” and War Memory: Fridrich Gorenshtein’s Autobiographical Story The House with a Turret
Creators: name: Rudova, Larissa
Publisher: name: AvtobiografiЯ

description: This article focuses on the representation of childhood in Fridrikh Gorenshtein’s (1932-2002) autobiographical story The House with a Turret (1964) that epitomizes the collective experience of his generation of Soviet children growing up during WWII. Much of Gorenshtein’s fiction could be described as autofiction, a term coined by the French writer and critical theorist Serge Dubrovsky, a narrative form that undermines the generic borders between autobiography and fiction. This article examines how in his autofiction, Gorenshtein redefines the boundaries of childhood by calling attention to two narrative perspectives: the child’s perception of the surrounding uncanny world and the adult narrator’s perception of the states of abjection, trauma, and neglect to which his young hero is subjected.

description: Autobiographical Recollections of the ‘Family Childhood’: The Adventures of Dzherik by Natalia Nusinova
This article offers a detailed cross-reading of Natalia Nusinova’s Adventures of Dzherik (2009), which is discussed as both an example of contemporary children’s literature and an autobiographical text. The novella is placed into the broader context of contemporary discussion over the nature of autobiographical genre, directly addressing the issue of the place of autobiography within the boundaries of children’s literature. Special attention is given to the multimodal function of this text as a combination of verbal and visual components. The story that combines fact and fiction and written for the dual audience of children and adults, relates to the complexity of soviet childhood experience as it is being presented through the eyes of a child and commented on by the adult author.

description: We set up a correspondence between solutions of the Yang-Mills equations on R×S3 and in Minkowski spacetime via de Sitter space. Some known Abelian and non-Abelian exact solutions are rederived. For the Maxwell case we present a straightforward algorithm to generate an infinite number of explicit solutions, with fields and potentials in Minkowski coordinates given by rational functions of increasing complexity. We illustrate our method with some nontrivial examples.

title: Besser dem Zufall vertrauen oder strategisch auswählen? Selektionsstrategien für archäologische Sammlungen
Creators: name: Karl, Raimund
Publisher: name: University Library Heidelberg

description: Archäologische Sammlungen und Archive leiden zunehmend unter Platznot und Ressourcenmangel. Funde in Depots sind oftmals selbst für WissenschaftlerInnen de facto und für die Öffentlichkeit ohnehin gänzlich unzugänglich; wenn sie nicht sogar in diesen auf Grund suboptimaler Lagerungsbedingungen vor sich hin verrosten, verschimmeln und verrotten. Der Auswertungsstand der in diesen Depots gelagerten archäologischen Quellen übersteigt selten einstellige Prozentsätze. Die meisten Archive sind voll, zahlreiche übervoll, manche müssen über Neuaufnahmestopps für Fundmaterial nachdenken. Resultat ist eine Selektion archäologischer Quellen durch das Zufallsprinzip. In diesem Beitrag wird argumentiert, dass es dringend nötig ist, bereits in der Feldforschung, dann in der Aufnahme und schließlich in der Revision von bestehenden Sammlungen radikale Selektionsstrategien zur Anwendung zu bringen. Nur durch diese wird es möglich sein, nicht nur den stetig fortschreitenden Neuanfall zusätzlichen Fundmaterials langfristig zu bewältigen, sondern auch tatsächlich eine nachhaltige Erhaltung wirklich wichtiger archäologischer Quellen sicherzustellen. Der durch radikale Selektion entstehende Überschuss an nicht erhaltenswerten Funden sollte hingegen kreativ zur Stärkung des öffentlichen Bewusstseins für die Wichtigkeit von Archäologie und zur Gewinnung zusätzlichen ökonomischen und sozialen Kapitals genutzt werden, das dann seinerseits zur weiteren Stärkung der Archäologie verwendet werden kann.
description: Archaeological archives increasingly suffer from space and resource shortages. Finds in stores increasingly are inaccessible to both scholars and the public; if they don’t slowly rust, mould or rot there due to suboptimal storage conditions. The percentage of the stored sources that have been analysed and published in any meaningful way rarely exceeds single figures. Most archives are full, many more than full, some have reached the point where they must consider refusing to take in new finds. This results in a selection of archaeological sources based on the principle of random sampling. In this contribution, it is argued that we direly need to adopt and apply radical strategic selection strategies, starting in the field during data collection, supplemented by further selection at the point of accessioning, and finally, in the revision of existing collections. Only this will allow us to cope in the long term not just with the continuing stream of new finds that must be collected, but also ensure a sustainable preservation of those sources that are truly important to maintain in perpetuity. The surplus created by radical selection, of finds not worthy of long term preservation, should in turn be used to strengthen public perception of the importance of archaeology and to gain additional economic and social capital, which in turn can be used to further strengthen archaeology.

description: This document encapsulates key recommendations resulting from the PD-AGE workshop, focusing on the critical decision of choosing non-human primate (NHP) species for modelling Parkinson's disease (PD) and understanding the impact of ageing on PD pathology. Through comprehensive discussions with experts, the workshop leaders discussed the irreplaceable role of NHP models and identified an ideal NHP species to model PD. The document provides a rationale for these choices and serves as a valuable guide for researchers navigating the selection of NHP species in PD and ageing studies, fostering informed decisions and advancing translational research in this crucial field.
