Medievalismus ohne Mittelalter? Die Anachronie der Bilder in Game of Thrones
Authors: Madersbacher Lukas 
Published: June 2022

ZusammenfassungDas mittelalterlich anmutende Design von Game of Thrones, seine Ansprüche und Wirkungsweisen wurden schon von unterschiedlichsten wissenschaftlichen Perspektiven aus in den Blick genommen. Einem Aspekt galt bislang aber kaum Aufmerksamkeit; der Frage nach der Rolle historischer Kunst in der Serie. Man würde eine Fokussierung auf mittelalterliche Settings und Artefakte erwarten. Doch bedient sich Game of Thrones des Motiv- und Stilrepertoires des gesamten Spektrums der Kunstgeschichte. Was auf den ersten Blick als beliebiger Eklektizismus erscheint, der historische Logik zugunsten visueller Effekte bricht, erweist sich bei eingehenderer Analyse durchaus als Strategie. Am einzelnen Beispiel lässt sich hinter den Sprüngen durch die Epochen das Kalkül erkennen, die Imagination historischer Ferne an die Lebenswelt der Gegenwart zu knüpfen und auf diese Weise rezeptiv aufzuschließen. Einerseits werden Zitate der Moderne in die historisierten Settings implantiert, umgekehrt populäre Motive mittelalterlicher Kunst, wie der Teppich von Bayeux, benutzt, um historische Plausibiliät und Identifikation zu generieren. Die jüngere Bildwissenschaft hat gezeigt, dass die Verschichtung unterschiedlicher Zeitebenen eine alte Technik des neuzeitlichen Bildes ist. Über die Anachronie von Bildern kann zeitliche Distanz ebenso erlebbar gemacht, wie das Vergangene mit der Gegenwart in Bezug gesetzt und damit andere Möglichkeiten rezeptiver Wirkung erzeugt werden, als es über rekonstruktive Bilder von Vergangenheit möglich wäre.
„If you think this has a happy ending, you haven’t been paying attention”. – Der Widerspruch von Serialität und Finalität bei Game of Thrones
Authors: Unterhuber Tobias 
Published: June 2022

ZusammenfassungDas Serienfinale von Game of Thrones wurde von Kritikerinnen und Kritikern und Fans gleichermaßen überwiegend negativ aufgenommen. Hierfür wurden vor allem handwerkliche Fehler der Showrunner verantwortlich gemacht sowie die fehlende Vorlage von George R. R. Martin. Diese Erklärung scheint aber zu kurz gegriffen. Vielmehr zeigt das Serienfinale grundlegende Probleme im Verhältnis von Serialität und Finalität auf, die gerade durch die Erwartung von Komplexitätssteigerung im Quality-TV noch multipliziert werden. Neben diesen strukturellen Gründen scheint es aber vor allem das Vorführen des eigenen Publikums zu sein, das entgegen der Konventionen der Serie dazu gebracht wurde, auf ein Happy End zu hoffen, nur um umso mehr enttäuscht zu werden. Dies wird ausführlich am Beispiel der Figur Daenerys Targaryen analysiert, die von der Serie zunächst als Heilsbringerin inszeniert wird, nur um ein umso tragischeres Ende zu finden. Dass dabei diese positive Inszenierung immer schon fragwürdig war, wurde vom Publikum lange Zeit ignoriert. Abschließend stellt der Beitrag die Frage, ob das Verschwinden von Game of Thrones aus dem öffentlichen Diskurs nicht auch in dem nicht-reproduzierbaren Ereignischarakter der Serie selbst begründet liegt.
Weyl covariance and the energy momentum tensors of higher-derivative free conformal field theories
Authors: Stergiou Andreas , Vacca Gian Paolo , Zanusso Omar 
Published: June 2022

Abstract
Energy momentum tensors of higher-derivative free scalar conformal field theories in flat spacetime are discussed. Two algorithms for the computation of energy momentum tensors are described, which accomplish different goals: the first is brute-force and highlights the complexity of the energy momentum tensors, while the second displays some features of their geometric origin as variations of Weyl invariant curved-space actions. New compact expressions for energy momentum tensors are given and specific obstructions to defining them as conformal primary operators in some spacetime dimensions are highlighted. Our discussion is also extended to higher-derivative free spinor theories, which are based on higher-derivative generalizations of the Dirac action and provide interesting examples of conformal field theories in dimension higher than two.

We compute the independent helicity amplitudes as well as the form factors for this process, expressing them in terms of hyperlogarithms with algebraic arguments. The Feynman integrals are computed by direct integration over Feynman parameters and the results are expressed in terms of a basis of rational prefactors.
Non-Gaussianities in the statistical distribution of heavy OPE coefficients and wormholes
Authors: Belin Alexandre , de Boer Jan , Liska Diego 
Published: June 2022

Abstract
The Eigenstate Thermalization Hypothesis makes a prediction for the statistical distribution of matrix elements of simple operators in energy eigenstates of chaotic quantum systems. As a leading approximation, off-diagonal matrix elements are described by Gaussian random variables but higher-point correlation functions enforce non-Gaussian corrections which are further exponentially suppressed in the entropy. In this paper, we investigate non- Gaussian corrections to the statistical distribution of heavy-heavy-heavy OPE coefficients in chaotic two-dimensional conformal field theories. Using the Virasoro crossing kernels, we provide asymptotic formulas involving arbitrary numbers of OPE coefficients from modular invariance on genus-g surfaces. We find that the non-Gaussianities are further exponentially suppressed in the entropy, much like the ETH. We discuss the implication of these results for products of CFT partition functions in gravity and Euclidean wormholes. Our results suggest that there are new connected wormhole geometries that dominate over the genus-two wormhole.
A new form of QCD coherence for multiple soft emissions using Glauber-SCET
Authors: Pathak Aditya 
Published: June 2022

Abstract
Amplitude-level factorization for a soft gluon emission has long been understood in terms of a product of loop-expanded soft-gluon currents and hard scattering matrix elements, both of which are infrared (IR) divergent. Thus, the amplitude for multiple soft gluon emissions, ordered in their relative softness, can be written as a product of IR divergent soft gluon currents and the matrix elements. In a more recent work, Angeles-Martinez, Forshaw and Seymour [1] (AMFS) showed that the result for this amplitude can in fact be re-expressed in an ordered evolution approach, involving IR finite one-loop insertions where the virtual loop momentum is constrained in a highly non-trivial way by the kT of the adjacent real emissions. The result thus exhibits a novel amplitude level QCD coherence where the IR divergences originating only from the very last, softest, gluon emission remain, and the rest cancel. The proof of the AMFS result at one-loop in QCD, however, involves many diagrams, and only after carefully grouping and summing over all the diagrams does the correct ordering variable emerge, making the higher order extension a challenging task. Moreover, the compact, Markovian nature of the final AMFS result is suggestive of a deeper underlying physics that is obscured in the derivation using traditional diagrammatic QCD. By considering a (recursive) sequence of effective field theories (EFTs) with Glauber-SCET operators, we present an elegant derivation of this result involving only a handful of diagrams. The SCET derivation offers clean physical insights, and makes a higher order extension of the AMFS result tractable. We also show that the grouping of QCD graphs necessary to derive the AMFS result in full theory is already implicit in the Feynman rules of Glauber-SCET operators such that the same result can alternatively be derived with significantly less effort in a single EFT with multiple ordered soft gluon emissions.

Published: June 2022

AbstractThis research work describes the development of a novel bioanalytical method for the assessment of food impact on selected exhaled breath volatile organic compounds (VOCs) using a fast and portable screening VOC prototype sensor based on membrane inlet mass spectrometry (MIMS). Method and sensor prototype functionality was verified by obtaining good response times, linearity in the examined concentration ranges, and sensitivity and repeatability for several breath VOCs—acetone, ethanol, n-pentane, and isoprene. A new VOC sensor prototype was also proven to be sensitive enough for selected breath VOC quantification with limits of detection at low part per billion (ppb) levels—5 ppb for n-pentane, 10 ppb for acetone and ethanol, and 25 ppb for isoprene. Food impact assessment was accomplished by tracking the levels of acetone, ethanol, n-pentane, and isoprene in exhaled breath samples collected from 50 healthy participants before the meal and 60 min and 120 min after the meal. For acetone, isoprene, and n-pentane, a larger impact was noticed 120 min after the meal, while for ethanol, it was after 60 min. Obtained VOC levels were in the expected concentration ranges. Mean values at all time points were ~ 500–900 ppb for acetone and ~ 400–600 ppb for ethanol. Most of the results for n-pentane were below 5 ppb, but the mean value for those which were detected was ~ 30 ppb. Along with samples, data about participants’ lifestyle were collected via a short questionnaire, which were compared against obtained VOC levels in order to reveal some significant correlations between habits of participants and their breath VOC levels.

The role of air–sea coupling on November–April intraseasonal rainfall variability over the South Pacific

Published: June 2022

AbstractWe investigate the impact of resolving air-sea interaction on the simulation of the intraseasonal rainfall variability over the South Pacific using the ECHAM5 atmospheric general circulation model coupled with the Snow-Ice-Thermocline (SIT) ocean model. We compare the fully coupled simulation with two uncoupled ECHAM5 simulations, one forced with sea surface temperature (SST) climatology and one forced with daily SST from the coupled model. The intraseasonal rainfall variability over the South Pacific is reduced by 17% in the uncoupled model forced with SST climatology and increased by 8% in the uncoupled simulation forced with daily SST, suggesting the role of air–sea coupling and SST variability. The coupled model best simulates the key characteristics of the two dominant patterns (modes) of intraseasonal rainfall variability over the South Pacific with reasonable propagation and correct periodicity. The spatial structure of the two rainfall modes in all three simulations is very similar, suggesting the dynamics of the atmosphere primarily generate these modes. The southeastward propagation of rainfall anomalies associated with two leading rainfall modes in the South Pacific depends upon the eastward propagating Madden–Julian Oscillation (MJO) signals from the Indian Ocean and western Pacific. Air-sea interaction improves such propagation as both eastward and southeastward propagations are substantially reduced in the uncoupled model forced with SST climatology. The simulation of both eastward and southeastward propagations considerably improved in the uncoupled model forced with daily SST; however, the periodicity differs from the coupled model. Such discrepancy in the periodicity is attributed to the changes in the SST-rainfall relationship with weaker correlations and the nearly in-phase relationship, attributed to enhanced positive latent heat flux feedbacks.
The neural signatures of psychoses in Alzheimer’s disease: a neuroimaging genetics approach
Authors: Manca Riccardo , Pardiñas Antonio F. , Venneri Annalena ,   for the Alzheimer’s Disease Neuroimaging Initiative
Published: June 2022

AbstractPsychoses in Alzheimer’s disease (AD) are associated with worse prognosis. Genetic vulnerability for schizophrenia (SCZ) may drive AD-related psychoses, yet its impact on brain constituents is still unknown. This study aimed to investigate the association between polygenic risk scores (PRSs) for SCZ and psychotic experiences (PE) and grey matter (GM) volume in patients with AD with (AD-PS) and without (AD-NP) psychosis. Clinical, genetic and T1-weighted MRI data for 800 participants were extracted from the ADNI database: 203 healthy controls, 121 AD-PS and 476 AD-NP. PRSs were calculated using a Bayesian approach and analysed at ten p-value thresholds. Standard voxel-based morphometry was used to process MRI data. Logistic regression models including both PRSs for SCZ and PE, and an AD-PRS were used to predict psychosis in AD. Associations between PRSs and GM volume were investigated in the whole sample and the three groups independently. Only the AD-PRS predicted psychosis in AD. Inconsistent associations between the SCZ-PRS and PE-PRS and GM volumes were found across groups. The SCZ-PRS was negatively associated with medio-temporal/subcortical volumes and positively with medial/orbitofrontal volumes in the AD-PS group. Only medio-temporal areas were more atrophic in the AD-PS group, while there was no significant correlation between psychosis severity and GM volume. Although not associated with psychoses, the SCZ-PRS was correlated with smaller medio-temporal and larger orbitofrontal volumes in AD-PS. Similar alterations have also been observed in SCZ patients. This finding suggest a possible disconnection between these regions associated with psychoses in more advanced AD.
The peperino rocks: historical and volcanological overview
Authors: Marra F. , Palladino D. M. , Licht O. A. Boni 
Published: June 2022

Abstract
The name peperino derives from the Italian word pepe (from the Latin word piper, pepper) and has been used in the common language for lithified volcanic deposits characterized by light grey through dark grey tones and granular textures, resembling that of ground pepper. Among these, the best-known examples are represented by some phreatomagmatic deposits of the Colli Albani Volcanic District, near Rome (Italy), and ignimbrite deposits of the Cimini Mountains near Viterbo (Northern Latium, Italy), which have been widely employed in artefacts of historical and archaeological interest. In particular, these resistant volcanic rocks have been widely employed by the Etruscans and Romans since the seventh century BCE to produce sarcophagi and dimension stones, as well as architectural and ornamental elements. These rocks are still in use for building ornaments, street furniture and artworks in central Italy today. In this review, we provide an overview of the use of this term, and an exhaustive review of the different rocks of central Italy defined as peperino, describing their distinctive textural features, as well as their eruptive sources and outcrop areas. Indeed, despite the common macroscopic aspect, peperino rocks can be associated with several different eruptive styles and emplacement mechanisms. Our review is also addressed to archaeologists concerned with restoration initiatives and provenance studies, as well as to volcanologists studying the genetic processes of pyroclastic rocks and related naming conventions.
Evaluation of a pneumonia multiplex PCR panel for detection of bacterial respiratory tract pathogens from serial specimens collected from hospitalized COVID-19 patients
Authors: Tellapragada Chaitanya , Ydsten Karin Andersson , Ternhag Anders , Giske Christian G. 
Published: June 2022

Abstract
We investigated the concordance between the Unyvero Hospitalized Pneumonia (HPN) application and quantitative culture for detection of bacterial pathogens from serial lower respiratory tract (LRT) specimens collected from the same subject. Comparison of results from HPN application and culture was evaluated using 69 LRT samples from 27 subjects, using two evaluation approaches. False positive detections by the HPN application was 29% (20/69) in Evaluation I vs 10% (7/68) in Evaluation II. Additional pathogens detected by the HPN application could be confirmed in many instances by culture positivity for the same organism from previous or subsequent samples from the same subject.
Algorithm substitution attacks against receivers
Authors: Armour Marcel , Poettering Bertram 
Published: June 2022

AbstractThis work describes a class of Algorithm Substitution Attack (ASA) generically targeting the receiver of a communication between two parties. Our work provides a unified framework that applies to any scheme where a secret key is held by the receiver; in particular, message authentication schemes (MACs), authenticated encryption (AEAD) and public key encryption (PKE). Our unified framework brings together prior work targeting MAC schemes (FSE’19) and AEAD schemes (IMACC’19); we extend prior work by showing that public key encryption may also be targeted. ASAs were initially introduced by Bellare, Paterson and Rogaway in light of revelations concerning mass surveillance, as a novel attack class against the confidentiality of encryption schemes. Such an attack replaces one or more of the regular scheme algorithms with a subverted version that aims to reveal information to an adversary (engaged in mass surveillance), while remaining undetected by users. Previous work looking at ASAs against encryption schemes can be divided into two groups. ASAs against PKE schemes target key generation by creating subverted public keys that allow an adversary to recover the secret key. ASAs against symmetric encryption target the encryption algorithm and leak information through a subliminal channel in the ciphertexts. We present a new class of attack that targets the decryption algorithm of an encryption scheme for symmetric encryption and public key encryption, or the verification algorithm for an authentication scheme. We present a generic framework for subverting a cryptographic scheme between a sender and receiver, and show how a decryption oracle allows a subverter to create a subliminal channel which can be used to leak secret keys. We then show that the generic framework can be applied to authenticated encryption with associated data, message authentication schemes, public key encryption and KEM/DEM constructions. We consider practical considerations and specific conditions that apply for particular schemes, strengthening the generic approach. Furthermore, we show how the hybrid subversion of key generation and decryption algorithms can be used to amplify the effectiveness of our decryption attack. We argue that this attack represents an attractive opportunity for a mass surveillance adversary. Our work serves to refine the ASA model and contributes to a series of papers that raises awareness and understanding about what is possible with ASAs.
Flight altitudes and flight activities of adult Red Kites (Milvus milvus) in the breeding area as determined by GPS telemetry
Authors: Pfeiffer Thomas , Meyburg Bernd-Ulrich 
Published: June 2022

AbstractThe Red Kite has come to the forefront of general consciousness in recent decades. A major contributing factor has been repeated collisions of these raptors with wind turbines and the important role they play in the approval process for new turbines. Efforts to improve their protection sometime encounter challenges due to limited knowledge about some life history aspects, e.g., their flight altitude and flight activity. We investigated these parameters from 2012 to 2018 in an approximately 1000-km2 study area in the vicinity of Weimar (Federal State of Thuringia, Federal Republic of Germany) in 29 breeding birds (19 males and 10 females) equipped with GPS loggers. In addition to more than 11 million GPS data records, accelerometer data from the loggers were evaluated. The start of morning activities correlated with sunrise. Most frequently, Red Kites initiated their first hunting flights immediately at sunrise; males started hunting at 9 min and females started hunting at 12 min after sunrise (medians). The Red Kites mostly foraged and hunted their prey during flight. The proportion of time spent flying during their activity phase was highest during midday hours, reaching 30–80% in males depending on the phase of the breeding season. For males, the time spent flying was approximately two and a half times that for females. The birds sporadically reached flight altitudes of up to 1600 m above ground in the breeding area, while they maintained lower altitudes between 5 and 60 m more frequently and predominantly while foraging (56% of location fixes). Higher altitudes were occupied much less frequently than lower altitudes and were often used to travel relatively long distances in an energy-saving manner. The end of activity was well before sunset, at 87 min prior to sunset for males and 154 min prior to sunset (medians) for females.
Does microhabitat use affect population differentiation? A test with southwestern Palaearctic forest birds
Authors: Talavera Adrián , Tellería José Luis 
Published: June 2022

AbstractWe tested whether microhabitat use affects dispersal and population differentiation in forest birds of the southwestern Palaearctic, a link previously suggested in Neotropical birds. To approach this, the number of subspecies within 32 species was used as a metric of population differentiation and was related to their feeding substrata and seasonal changes in abundance (a surrogate of dispersal) in a mountain range (Guadarrama Mountains, Central Spain). Multivariate analyses in which the effect of range size (a main correlate of within-species diversification) and phylogeny relatedness were considered, showed that those birds adapted to exploit the tree canopy had lower seasonal changes in abundance and more subspecies than ground-dweller birds. Our results support a cause-effect link between the use of stable resources in the canopy, seasonal movements and population differentiation of birds from temperate forests of the southwestern Palaearctic.
On the Non-monotonic Variation of the Entrainment Buoyancy Flux with Wind Shear
Authors: Fodor Katherine , Mellado Juan Pedro , Haghshenas Armin 
Published: June 2022

AbstractThe magnitude of the entrainment buoyancy flux, and hence the growth rate of the convective boundary layer, does not increase monotonically with wind shear. Explanations for this have previously been based on wind-shear effects on the turbulence kinetic energy. By distinguishing between turbulent and non-turbulent regions, we provide an alternative explanation based on two competing wind-shear effects: the initial decrease in the correlation between buoyancy and vertical velocity fluctuations, and the increase in the turbulent area fraction. The former is determined by the change in the dominant forcing; without wind shear, buoyancy fluctuations drive vertical velocity fluctuations and the two are thus highly correlated; with wind shear, vertical velocity fluctuations are partly determined by horizontal velocity fluctuations via the transfer of kinetic energy through the pressure–strain correlation, thus reducing their correlation with the buoyancy field. The increasing turbulent area fraction, on the other hand, is determined by the increasing shear production of turbulence kinetic energy inside the entrainment zone. We also show that the dependence of these conditional statistics on the boundary-layer depth and on the magnitude of the wind shear can be captured by a single non-dimensional variable, which can be interpreted as an entrainment-zone Froude number.
