description: The article is devoted to the problem of relationship between Russian Federation and NATO in the XXI century. The relevance of the question is indisputable considering the fact that the global stability in the world depends on both positive or negative tendencies in this relationship. Since the collapse of the Soviet Union the new quality of cooperation between NATO and Russia seemed to be outworked. But still there is a huge list of factors and unsolved problems between this two key actors of the international relations which cannot grant permanent security and stability in the world. The present-day crisis that forms the political and international agenda today grows on the soil of this complex of issues which were either ignored or underestimated in the 1990-s first decade of the 2000-s and now we just yield what we've got. The article doesn't have the objection to analyze the ongoing crisis in Ukraine or disagreements between Russia and the USA on Syria e t.c. The authors wanted to analyze prehistorical backgrounds of the relationship between NATO and Russia and, maybe, reveal some crucial points responsible for turning this relationship on the road of new confrontation. That's why our research chronologically includes two decades past the collapse of the USSR (1991-2012). The authors consider that it was the crucial time when the fundamental basis of the potential cooperation between Russia and NATO was formed. Working on the material the authors applied to the methodology of political science and international relations. The methods of political analysis, structural analysis and invent-analysis (studying the official documents) were used in the article. For the better understanding of the issue and in order to prevent the readers from the danger of being “over-informed” the authors divided the material into two parts. The first part published in №1 of the Journal was devoted to the historical analysis of the Cold War. The second one, introduced in this number, reflects the post-Cold war situation in the world in the last decade of the XX-first decade of the XXI-st centuries.
title: Moral im Nationalsozialismus
Creators: name: Prattes, Vanessa
Year: 2021

description: Im Zentrum der Arbeit steht die Grundannahme, dass sich in der Propaganda eine spezifische nationalsozialistische Moral manifestierte, die mit optischen Mitteln verfestigt wurde. Dies wird anhand von Filmaufnahmen aus dem Warschauer Ghetto untersucht. Die Aufnahmen wurden im Mai 1942 im Ghetto gedreht, sind aber nie in den Korpus eines Propagandafilms eingebettet worden. Folgende Fragen stehen im Mittelpunkt der Analyse: Durch welche Visualisierungsstrategien werden im Filmmaterial Emotionen erzeugt, die zur Umschreibung von Wertesystemen beitragen und die Verankerung des Antisemitismus der Volksgemeinschaft verstärken? Anhand der Kategorien: Der Jude im Ghetto, Der Jude als Fremder, Der Jude als Parasit, Der Jude und das Geld und Der Jude als Bedrohung für Blut und Boden werden die propagandistischen Visualisierungsstrategien der Fotografien sowie deren emotionale Wirkung herausgearbeitet. Die Analyse der einzelnen antisemitischen Topoi konnte zeigen, welche moralischen Schemata in den Aufnahmen transportiert werden. Die Aufnahmen nehmen somit eine mobilisierende Rolle ein und können als aktives Element der nationalsozialistischen Vernichtungspolitik gesehen werden, da sie die "Endlösung" ideologisch vorbereiten und politische Maßnahmen mit antisemitischen Bildformeln legitimieren.
description: At the center of the research is the basic assumption that a specific National Socialist morality manifested itself in propaganda and was visually substantiated through visual means. This is examined based on footage shot in the Warsaw Ghetto in May 1942, but never embedded in the corpus of a propaganda film. The following questions are at the center of the analysis: Through which visualization strategies are emotions generated in the footage that ultimately contribute to the rewriting of value systems and strengthened the anchoring of the anti-Semitism of the Volksgemeinschaft? Using the categories: The Jew in the Ghetto, The Jew as Stranger, The Jew as Parasite, The Jew and Money, and The Jew as Threat to Blood and Soil, propagandistic visualization strategies of the photographs as well as their emotional impact will be elaborated. The analysis of the individual anti-Semitic topoi was able to show which moral schemata were transported in the footage. The footage thus take on a mobilizing role and can be seen as an active element of the National Socialist extermination policy, as they ideologically prepare for the "Final Solution" and legitimize political measures with anti-Semitic image formular.

description: Let $F$ be a field with positive odd characteristic $p$. We prove a variety of new sum-product type estimates over $F$. They are derived from the theorem that the number of incidences between $m$ points and $n$ planes in the projective three-space $PG(3,F)$, with $m\geq n=O(p^2)$, is $$O( m\sqrt{n} + km ),$$ where $k$ denotes the maximum number of collinear planes. The main result is a significant improvement of the state-of-the-art sum-product inequality over fields with positive characteristic, namely that \begin{equation}\label{mres} |A\pm A|+|A\cdot A| =Ω\left(|A|^{1+\frac{1}{5}}\right), \end{equation} for any $A$ such that $|A|
description: This is a revised version: Theorem 1 was incorrect as stated. We give its correct statement; this does not seriously affect the main arguments throughout the paper. Also added is a seres of remarks, placing the result in the context of the current state of the art

description: Haag's theorem cries out for explanation and critical assessment: it sounds the alarm that something is (perhaps) not right in one of the standard way of constructing interacting fields to be used in generating predictions for scattering experiments. Viewpoints as to the precise nature of the problem, the appropriate solution, and subsequently-called-for developments in areas of physics, mathematics, and philosophy differ widely. In this paper, we develop and deploy a conceptual framework for critically assessing these disparate responses to Haag's theorem. Doing so reveals the driving force of more general questions as to the nature and purpose of foundational work in physics.

description: Residual errors in shear measurements, after corrections for instrument systematics and atmospheric effects, can impact cosmological parameters derived from weak lensing observations. Here we combine convergence maps from our suite of ray-tracing simulations with random realizations of spurious shear. This allows us to quantify the errors and biases of the triplet $(Ω_m,w,σ_8)$ derived from the power spectrum (PS), as well as from three different sets of non-Gaussian statistics of the lensing convergence field: Minkowski functionals (MF), low--order moments (LM), and peak counts (PK). Our main results are: (i) We find an order of magnitude smaller biases from the PS than in previous work. (ii) The PS and LM yield biases much smaller than the morphological statistics (MF, PK). (iii) For strictly Gaussian spurious shear with integrated amplitude as low as its current estimate of $σ^2_{sys}\approx 10^{-7}$, biases from the PS and LM would be unimportant even for a survey with the statistical power of LSST. However, we find that for surveys larger than $\approx 100$ deg$^2$, non-Gaussianity in the noise (not included in our analysis) will likely be important and must be quantified to assess the biases. (iv) The morphological statistics (MF,PK) introduce important biases even for Gaussian noise, which must be corrected in large surveys. The biases are in different directions in $(Ω_m,w,σ_8)$ parameter space, allowing self-calibration by combining multiple statistics. Our results warrant follow-up studies with more extensive lensing simulations and more accurate spurious shear estimates.

description: The accretion of matter onto primordial black holes (PBHs) during the dark ages and the subsequent energy injection in the medium should have left imprints on the cosmic microwave background (CMB) anisotropies. Recent works have claimed stringent CMB limits on the PBH abundance, hardly compatible with a PBH interpretation of the gravitational-wave observations of binary BH mergers. By using a more realistic accretion model based on hydrodynamical simulations and conservative assumptions for the emission efficiency, we show that CMB limits on the PBH abundance are up to two orders of magnitude less stringent than previously estimated between $10$ and $10^4$ M$_\odot$. This reopens the possibility that PBHs might explain at the same time (at least a fraction of) the dark matter, some of the LIGO-Virgo-KAGRA binary BH mergers and the existence of super-massive BHs. More generally, we emphasize that PBH accretion can be a rather complex physical process with velocity dependences that are hard to assess, which introduces large uncertainties in accretion-based limits on the PBH abundance.

description: We consider Gaussian quantum circuits that alternate unitary gates and post-selected weak measurements, with spatial translation symmetry and time periodicity. We show analytically that such models can host different kinds of measurement-induced phase transitions detected by entanglement entropy, by mapping the time evolution and weak measurements to Möbius transformations. We demonstrate the existence of a log-law to area-law transition, as well as a volume-law to area-law transition. For the latter, we compute the critical exponent $ν$ for the Hartley, von Neumann and Rényi entropies exactly.

description: The main goal of work package 4 is to increase the performance of oceanographic observatories in Europe. One major point is the formulation and the evaluation of best practises of sensor calibration. This is an issue of great interest for institutions dealing with different (automated) observation systems. So, this report is providing information about the best practises for sensor calibration of different types of sensors. Each sensor type has typical characteristics, which have to be addressed when calibration routine has to be applied to the sensor. This is outlined in the next sections for the different sensor types. However, there are also several general advices for sensor calibration which are valid for any sensor when reliable sensor data are needed. Temperature and conductivity sensors cannot be calibrated in the field, so thoroughly lab calibration is necessary, i.e. the preparing and maintaining of temperature baths. For Chlorophyll sensors it is generally agreed that FChla measurements do not necessarily reflect true analytically measured [Chla], so this has to be taken into account when calibrating chlorophyll fluorescence sensors. No generally accepted method for fluorometer calibration exists, so also manufacturers have different conventions. Various solutions for primary fluorometer calibration include factory calibration, use of algae cultures, chemical standards dissolved in water or in various solvents, or solid standards. Calibration of chemical sensors relies strongly on proper handling of water samples and reagents and the preparing of standard solutions. Monitoring of more than one nutrient parameter with one device has to be carried out carefully. For oxygen sensors the according calibration routine relies on comparing lab analyses via Winkler titration which needs some experience to carry out including proper sampling. A wide range of different concentration levels and different temperature levels must be used for calibration of optical oxygen sensors.

description: Центральноазиатский регион является сегодня одним из наиболее «взрывоопасных». Тому есть несколько причин. Первая заключается в том, что с момента дезинтеграции единого советского пространства обороны и безопасности, гарантированных в рамках СССР в течение более 70 лет, образовался колоссальный идейно-политический, идеологический и духовный вакуум, заполнить который неизбежно стремятся те силы, которые рассчитывают закрепить свои позиции в регионе. Не в последнюю очередь это относится к различным организациям радикального исламского и псевдо-религиозного толка. Вторая причина кроется в том, что одним из основных источников угроз безопасности центрально-азиатского региона СНГ с начала 90-х гг. ХХ столетия остается хроническая неурегулированность афганской проблемы. Восстановление мира и стабильности в Афганистане одна из актуальных международных и региональных проблем, прежде всего, для государств Центральной Азии, напрямую сталкивающихся с негативными последствиями многолетней войны в этой стране. Конфликт в Афганистане породил угрозы и вызовы стабильности и безопасности стран Центральной Азии, переживающих сложный этап становления и укрепления своей государственности, такие, как религиозный экстремизм, этническая нетерпимость, терроризм, наркобизнес и контрабанда оружия. Кроме того, возможность переноса конфликтной ситуации из Афганистана в страны СНГ отнюдь не является гипотетичной. Прежде всего, потому, что по обе стороны границ проживают представители одних и тех же этносов, веками связанных друг с другом узами историко-культурной общности, а подчас и родства. Все эти фактора обусловливают сложность решения проблемы, традиционные политические или гуманитарные подходы к которой в данном случае не работают. Используя методологию политической науки (метод политанализа) и исторической науки (историко-аналитический метод, метод сравнения и метод ретроспективной оценки), автор попытался выявить ключевые закономерности, характерные для процессов, протекающих в регионе в течение последних трех десятилетий.

description: In this work we derive the general conditions for obtaining nonreciprocity in multi-mode parametrically-coupled systems. The results can be applied to a broad variety of optical, microwave, and hybrid systems including recent electro- and opto-mechanical devices. In deriving these results, we use a graph-based methodology to derive the scattering matrix. This approach naturally expresses the terms in the scattering coefficients as separate graphs corresponding to distinct coupling paths between modes such that it is evident that nonreciprocity arises as a consequence of multi-path interference and dissipation in key ancillary modes. These concepts facilitate the construction of new devices in which several other characteristics might also be simultaneously optimized. As an example, we synthesize a novel three-mode unilateral amplifier design by use of graphs. Finally, we analyze the isolation generated in a common parametric multi-mode system, the DC-SQUID.

Contrasting farmers' perception of climate change and climatic data: How (in)consistency supports risk reduction and resilience?

Publisher: name: Zenodo

description: Farmers’ adaptation to climate change is a two-step process that involves perceiving stressors and identifying impacts to respond to variability and changes through specific actions and strategies. Hence, successful adaptation depends on how well changing climate is perceived, either from a ‘bottom-up’ pathway –where farmers observe and identify changes through past experience–, or by using a ‘top-down’ pathway –where changes are identified through climate records. A gap between both pathways tends to be related to farmers’ misperception. For example, as life experiences influence perception, farmers who have been directly affected by extreme climatic events tend to report that the probability of such event happening again is relatively high. Furthermore, as perception is in part a subjective phenomenon, therefore, different farmers in the same locality might construct different perceptions of climate change impacts even though they experience the same weather patterns. Consequently, increased attention has been put on combining the ‘civic science’ of farmers’ perceptions with the ‘formal science’ from meteorological reports to identify the (in)consistency between perceived and observed data and how this affect farmers’ resilience when facing climate change impacts. This contribution provides a review comparing farmers’ perception and climate observations to address a twofold research question: 1) Which extreme events and compound risks are perceived by farmers in contrast with observed data? And 2) How do past experiences and social-learning influence farmers’ resilience and their adaptive capacity? We analyze a portfolio of 147 articles collected from Scopus library catalogue since 2000. The bibliometrics analysis was coupled with the systematic review to 103 articles selected from the original portfolio. Comparison between perceived and observed changes were focus on what was changing (onset, duration or cessation regarding temperature and rainfall patterns) and how it was changing (amount, frequency, intensity or inter-annual variability). Results will be useful for managers, developers, and policymakers of climate adaptation strategies to be more in tune with farmers’ understandings of when and how weather is changing. Furthermore, the review could generate recommendations for the design, formulation, and implementation of adaptation policies that are better tailored to farmers’ perception at local conditions, being more efficient and conducive to risk analysis when facing climate change.

description: Within exact electron density-functional theory, we investigate Kohn-Sham (KS) potentials, orbital energies, and non-interacting kinetic energies of the fractional ions of Li, C and F. We use quantum Monte Carlo densities as input, which are then fitted, interpolated at non-integer electron numbers $N$, and inverted to produce accurate KS potentials $v_s^N(r)$. We study the dependence of the KS potential on $N$, and in particular we numerically reproduce the theoretically predicted spatially constant discontinuity of $v_s^N(r)$ as $N$ passes through an integer. We further show that, for all the cases considered, the inner orbital energies and the non-interacting kinetic energy are nearly piecewise linear functions of $N$. This leads us to propose a simple approximation of the KS potential $v_s^N(r)$ at any fractional electron number $N$ which uses only quantities of the systems with the adjacent integer electron numbers.

description: Phase fluctuations determine the low-energy properties of quantum condensates. However, at the condensation threshold, both density and phase fluctuations are relevant. While strong emphasis has been given to the investigation of phase fluctuations, which dominate the physics of the quantum system away from the critical point -- number fluctuations have been much less explored, even in thermal equilibrium. In this work, we report experimental observation and theoretical description of fluctuations in a circularly-confined non-equilibrium Bose-Einstein condensate of polaritons near the condensation threshold. We observe critical fluctuations, which combine the number fluctuations of a single-mode condensate state and competition between different states. The latter are analogous to mode hopping in photon lasers. Our theoretical analysis indicates that this phenomenon is of a quantum character, while classical noise of the pump is not sufficient to explain the experiments. The manifestation of a critical quantum state competition unlocks new possibilities for the study of condensate formation while linking to practical realizations in photonic lasers.

description: Fluctuations in a fluid are strongly affected by the presence of a macroscopic gradient making them long-ranged and enhancing their amplitude. While small-scale fluctuations exhibit diffusive lifetimes, larger-scale fluctuations live shorter because of gravity, as theoretically and experimentally well-known. We explore here fluctuations of even larger size, comparable to the extent of the system in the direction of the gradient, and find experimental evidence of a dramatic slowing-down in their dynamics. We recover diffusive behaviour for these strongly-confined fluctuations, but with a diffusion coefficient that depends on the solutal Rayleigh number. Results from dynamic shadowgraph experiments are complemented by theoretical calculations and numerical simulations based on fluctuating hydrodynamics, and excellent agreement is found. The study of the dynamics of non-equilibrium fluctuations allows to probe and measure the competition of physical processes such as diffusion, buoyancy and confinement.

description: We present several examples of fundamental problems involving weak continuity and compactness for nonlinear partial differential equations, in which compensated compactness and related ideas have played a significant role. We first focus on the compactness and convergence of vanishing viscosity solutions for nonlinear hyperbolic conservation laws, including the inviscid limit from the Navier-Stokes equations to the Euler equations for homentropy flow, the vanishing viscosity method to construct the global spherically symmetric solutions to the multidimensional compressible Euler equations, and the sonic-subsonic limit of solutions of the full Euler equations for multidimensional steady compressible fluids. We then analyze the weak continuity and rigidity of the Gauss-Codazzi-Ricci system and corresponding isometric embeddings in differential geometry. Further references are also provided for some recent developments on the weak continuity and compactness for nonlinear partial differential equations.

description: We show that the continuum limit of moiré graphene is described by a $(2+1)$-dimensional field theory of Dirac fermions coupled to two classical vector fields: a periodic gauge and spin field. We further show that the existence of a flat band implies an effective dimensional reduction, where the time dimension is ``removed.'' The resulting two-dimensional Euclidean theory contains the chiral anomaly. The associated Atiyah-Singer index theorem provides a self-consistency condition for flat bands. In the Abelian limit, where the spin field is disregarded, we reproduce a periodic series of quantized magic angles known to exist in twisted bilayer graphene in the chiral limit. However, the results are not exact. If the Abelian field has zero total flux, perfectly flat bands can not exist, because of the leakage of edge states into neighboring triangular patches with opposite field orientations. We demonstrate that the non-Abelian spin component can correct this and completely flatten the bands via an effective renormalization of the Abelian component into a configuration with a non-zero total flux. We present the Abelianization of the theory where the Abelianized flat band can be mapped to that of the lowest Landau level. We show that the Abelianization corrects the values of the magic angles consistent with numerical results. We also use this criterion to prove that an external magnetic field splits the series into pairs of magnetic field-dependent magic angles associated with flat moiré-Landau bands. The topological criterion and the Abelianization procedure provide a generic practical method for finding flat bands in a variety of material systems including but not limited to moiré bilayers.

description: We consider massive $SU(N)$ gauge theory with fermions. Gauge bosons become massive due to the interaction with the scalar field, whose vacuum average provides the spontaneous breakdown of gauge symmetry. We investigate Dyson - Schwinger equation for the fermion propagator written in ladder approximation and in Landau gauge. Our analysis demonstrates that the chiral symmetry breaking in the considered theory is the strong coupling phenomenon. There are the indications that there appears the second order phase transition between chirally broken and symmetric phases of the theory at the value of coupling constant $α_c = (1+γ)\times \fracπ{3}\times \frac{1}{2 C_2(F)}$, where $0

description: Die Arbeit beschäftigt sich mit barocken Kunstwerken aus der reichen Sammlung des kärntnerischen Benediktinerstiftes St. Paul im Lavanttal, die die Themen Tod und Vergänglichkeit zum Inhalt haben. Im Mikrokosmos einer Klostersammlung, die aus ihrer Geschichte mächtige Erzählungen schöpft, ist es Ziel dieser Arbeit, Kunstwerke am Schnittpunkt von Kunst und Philosophie zu vernetzen. Nach dem Erläutern philosophischer und religiöser Meilensteine im Nachdenken über Tod und Vergänglichkeit sowie dem Vorstellen der Sammlungsgeschichte des Stiftes St. Paul werden im Hauptteil der Arbeit Kunstwerke, überwiegend Gemälde und Graphik, aus der barocken Epoche teilweise erstmalig in dieser Tiefe analysiert. Einerseits werden damit bereits erzielte Forschungsergebnisse gefestigt und untermauert, andererseits neue wissenschaftliche Erkenntnisse erzielt.
description: The thesis deals with Baroque artworks from the rich collection of the Carinthian Benedictine monastery of St. Paul in the Lavant valley, which have death and transience as their subject of matter. In the microcosm of a monastery collection that draws powerful narratives from its history, the aim of this thesis is to link artworks at the intersection of art and philosophy. After explaining philosophical and religious milestones in thinking about death and transience and introducing the history of the St. Paul Monastery’s collection, the main part of the thesis analyses works of art, predominantly paintings and graphic art, from the Baroque era, in some cases for the first time in such depth. On the one hand, this consolidates and substantiates research results already achieved, and on the other hand, it provides new scientific insights.

Induced almost para-Kähler Einstein metrics on cotangent bundles

description: In earlier work we have shown that for certain geometric structures on a smooth manifold $M$ of dimension $n$, one obtains an almost para-Kähler--Einstein metric on a manifold $A$ of dimension $2n$ associated to the structure on $M$. The geometry also associates a diffeomorphism between $A$ and $T^*M$ to any torsion-free connection compatible with the geometric structure. Hence we can use this construction to associate to each compatible connection an almost para-Kähler--Einstein metric on $T^*M$. In this short article, we discuss the relation of these metrics to Patterson--Walker metrics and derive explicit formulae for them in the cases of projective, conformal and Grassmannian structures.

description: В статье рассматриваются перспективы развития в Республике Беларусь сценария «цветной революции». Автор изучает феномен «цветной революции» и факторы, детерминирующие его применение. Доказывается, что «цветная революция» есть суть верхушечный государственный переворот. Показано, что события, произошедшие в Беларуси в феврале-марте 2017 г. попыткой осуществить «цветную революцию» не являлись. Выявлены условия, которые на данном этапе препятствуют реализации сценария по демонтажу политического режима в Беларуси. В частности, к таковым отнесена лояльность силовиков действующему в стране политическому режиму. Вместе с тем отмечены и обстоятельства, которые способны поощрить будущий протест в Беларуси, к таковым автор относит рост националистических настроений в республике.

description: Introduction Major depression affects over 300 million people worldwide, but cases are often detected late or remain undetected. This increases the risk of symptom deterioration and chronification. Consequently, there is a high demand for low threshold but clinically sound approaches to depression detection. Recent studies show a great willingness among users of mobile health apps to assess daily depression symptoms. In this pilot study, we present a provisional validation of the depression screening app Moodpath. The app offers a 14-day ambulatory assessment (AA) of depression symptoms based on the ICD-10 criteria as well as ecologically momentary mood ratings that allow the study of short-term mood dynamics. Materials and methods N = 113 Moodpath users were selected through consecutive sampling and filled out the Patient Health Questionnaire (PHQ-9) after completing 14 days of AA with 3 question blocks (morning, midday, and evening) per day. The psychometric properties (sensitivity, specificity, accuracy) of the ambulatory Moodpath screening were assessed based on the retrospective PHQ-9 screening result. In addition, several indicators of mood dynamics (e.g. average, inertia, instability), were calculated and investigated for their individual and incremental predictive value using regression models. Results We found a strong linear relationship between the PHQ-9 score and the AA Moodpath depression score (r = .76, p < .001). The app-based screening demonstrated a high sensitivity (.879) and acceptable specificity (.745). Different indicators of mood dynamics covered substantial amounts of PHQ-9 variance, depending on the number of days with mood data that were included in the analyses. Discussion AA and PHQ-9 shared a large proportion of variance but may not measure exactly the same construct. This may be due to the differences in the underlying diagnostic systems or due to differences in momentary and retrospective assessments. Further validation through structured clinical interviews is indicated. The results suggest that ambulatory assessed mood indicators are a promising addition to multimodal depression screening tools. Improving app-based AA screenings requires adapted screening algorithms and corresponding methods for the analysis of dynamic processes over time.

description: Decomposition puzzles are pencil-and-paper logic puzzles that involve partitioning a rectangular grid into several regions to satisfy certain rules. In this paper, we construct a generic card-based protocol called printing protocol, which can be used to physically verify solutions of decompositon puzzles. We apply the printing protocol to develop card-based zero-knowledge proof protocols for two such puzzles: Five Cells and Meadows. These protocols allow a prover to physically show that he/she knows solutions of the puzzles without revealing them.

description: A total of 256 fecal specimens were randomly collected from farmed poultry in Germany and screened for the presence of Cryptosporidium spp. by PCR and further characterized by direct automated DNA sequencing. Using a nested PCR amplifying approximately 830 bp 18S rDNA fragment, 7.03% (n = 18) of the samples were Cryptosporidium-positive. In detail, Cryptosporidium was detected in 9.3% (8/86) of turkeys, 5.7% (9/158) of broilers and 8.3% (1/12) of layers. After DNA sequencing, Cryptosporidium parvum the most frequently observed species was identified in 5.1% (13/256) of all poultry species, including 8.1% (7/86) of turkeys, 3.2% (5/158) of broilers and 8.3% (1/12) of layers. Cryptosporidium baileyi was detected in 1.3% (2/256) of the broilers only. Three novel unclassified Cryptosporidium spp. were detected in 1.2% (1/86) of turkeys and 1.3% (2/158) of broilers. The infection rate was high in 13–20 week old turkeys, 1–6 weeks old broilers and >20 weeks old layers but differences between age groups were not significant. This is the first study in Germany uses molecular methods for the detection of Cryptosporidium in poultry. The results indicate that Cryptosporidium parasites are common among broilers and turkeys in Germany. Considering the large size of the poultry industry, the large amount of poultry meat that is consumed and the fact that C. parvum is also the most common Cryptosporidium parasite in humans, poultry might also be a source of human infections.
