description: Thema: Husten ist das häufigste Symptom, bei dem Personen ärztlichen Rat suchen. Die gewöhnliche Erkältung stellt die bekannteste Ursache dar. Darüber hinaus sind steigende Hustenraten mit einer Verschlechterung des Gesundheitszustands bei Krankheiten wie Asthma und COPD assoziiert. Infolgedessen wurden viele Anstrengungen unternommen, um ein objektives Mass für Husten zu schaffen. Bis heute gibt es jedoch keine standardisierte Methode, und es gibt keinen ausreichend validierten generischen Hustenmonitor, der im Handel erhältlich und klinisch akzeptabel ist.
Zielsetzung: Ziel dieses Projekts ist es, die Smartphone-basierte Hustenerkennung über 24 Stunden bei 22 COPD-Patienten zu validieren und die erkannten Hustenzahlen mit menschlichen Annotatoren zu vergleichen.
Methode: Für das Android-Betriebssystem wurde eine App zur Hustenerkennung entwickelt. Die Detektion des Hustens basiert auf einen Ensemble-Klassifikator von fünf Convolutional Neural Networks. Die App fungiert auch als Audiorecorder, sodass die Erkennung anschliessend verifiziert werden kann. Zusätzlich werden Hustendetektionen an einen Studienserver gesendet und können in Echtzeit über einen Web-Client verfolgt werden.
Ergebnisse: Für das Trainieren von Hustenklassifikationsmodellen wurden Audiodaten von 94 Erwachsenen mit Asthma (57% Frauen, Durchschnittsalter 43 Jahre) verwendet, die über 29 Nächte aufgezeichnet wurden. Insgesamt wurden 704.697 Geräusche benutzt, von denen 30.304 als Husten identifiziert wurden. Der Ensemble-Klassifikator wurde vor der Studie auf dem PC evaluiert und schnitt mit einem Matthews-Korrelationskoeffizienten von 94.4% ab. Ob diese Ergebnisse auf dem Smartphone mit COPD Patienten im Krankenhauszimmer oder zu Hause reproduzierbar sind, wird in diesem Projekt erforscht.
Fazit: Smartphone-basierte Hustenerkennung kann einen skalierbaren, kostengünstigen Marker für chronische Atemwegserkrankungen liefern.

description: We observe a relation between closed strings tachyons and one-loop instabilities in non-supersymmetric non-commutative gauge theories. In particular we analyze the spectra of type IIB string theory on C^3/Z_N orbifold singularities and the non-commutative field theory that lives on D3 branes located at the singularity. We find a surprising correspondence between the existence or not of one-loop low-momentum instabilities in the non-commutative field theory and the existence or not of tachyons in the closed string twisted sectors. Moreover, the relevant piece of the non-commutative field theory effective action is suggestive of an exchange of closed string modes. This suggests that non-commutative field theories retain some information about the dynamics of the underlying string configuration. Finally, we also comment on a possible relation between closed string tachyon condensation and field theory tachyon condensation.

 Type host and type locality
 Myliobatis tobijei Bleeker (Rajiformes: Myliobatidae); Taiwan Strait, off Chongwu, Fujian Province, China.
 Site of infection
Stomach.
 Material examined
 Paratypes (one male, one female), collected from M. tobijei; Taiwan Strait, off Chongwu, Fujian Province, China; deposited in Institute of Zoology, Chinese Academy of Sciences (IZ-CAS).
 Remarks
 Yin & Zhang (1983) reported Raphidascaroides myliobatum from the stomach of the Japanese eagle ray Myliobatis tobijei Bleeker (Rajiformes: Myliobatidae) from the Taiwan Strait (off Chongwu, Fujian Province, China). We examined a pair of paratypes of this species and the morphology of R. myliobatum is identical with the diagnostic characters of Mawsonascaris including the lips possessing dentigerous ridges, the presence of interlabia and a gubernaculum, the absence of a ventricular appendage and the spicules being distinctly unequal. Therefore, we have transferred this species to Mawsonascaris. In the genus Mawsonascaris, M. myliobatum can be easily distinguished from congeners by the number of caudal papillae (26–28 pairs in the former versus 14–17 pairs in congeners).

description: Hintergrund: Langsames Atmen hat eine positive Wirkung auf die Herzfunktion und auf das psychische Wohlbefinden. Daher werden entsprechende Atemübungen oft bei chronischen Krankheiten empfohlen; sie werden allerdings aus verschiedenen Gründen nur von bestimmten Personengruppen ausgeübt und haben somit eine eingeschränkte Reichweite und Wirkung.
Ziel: Die Breeze App verfolgt das Ziel, die Reichweite von Atemübungen mit einem spielerischen und skalierbaren Biofeedback-Ansatz zu erhöhen.
Methode: Grundlage der Atemübung Breeze ist die Erkennung der Atmung mit dem Mikrofon des Smartphones, um damit beim Ausatmen «Rückenwind» für ein virtuelles Segelboot zu erzeugen und es somit zu beschleunigen. Entspricht der Atmungs-Zyklus einem validierten Muster (z.B. 4s Einatmung, 2s Ausatmung und 4s Pause), kann mit dem Segelboot, welches in Echtzeit auf dem Bildschirm des Smartphones dargestellt wird, die grösste Reisedistanz zurückgelegt werden. Es wurden Labor- und Online-Experimente durchgeführt, um Breeze hinsichtlich physiologischer Effekte und subjektiver Einschätzungen bei erwachsenen Personen zu evaluieren.
Ergebnisse: Im Labor (N=16) konnte gezeigt werden, dass Breeze nicht nur zu einer Steigerung der Herzfrequenzvariabilität geführt hat (p<.001), sondern auch gegenüber einer validierten Atemübung ohne spielerischen Ansatz von 14 (87.5%) Personen präferiert wurde. Ein Online-Experiment mit Teilnehmenden, welche im Schnitt nur wenig bis gar keine Erfahrung mit Atemübungen hatten, zeigte darüber hinaus, dass die wahrgenommene Entspannung durch Breeze (N=88) mit der einer validierten Atemübung (N=82) vergleichbar ist und 51 (58.0%) Personen Breeze im Alltag nutzen würden.
Zusammenfassung: Breeze hat mit seinem spielerischen Ansatz das Potential, die Reichweite von Atemübungen zu erhöhen, was insbesondere für das Selbstmanagement bei chronischen Krankheiten relevant sein kann.

description: We study the extremal properties of a stochastic process xt defined by the Langevin equation ẋₜ =√2Dₜ ξₜ, in which ξt is a Gaussian white noise with zero mean and Dₜ is a stochastic‘diffusivity’, defined as a functional of independent Brownian motion Bₜ.We focus on threechoices for the random diffusivity Dₜ: cut-off Brownian motion, Dₜt ∼ Θ(Bₜ), where Θ(x) is the Heaviside step function; geometric Brownian motion, Dₜ ∼ exp(−Bₜ); and a superdiffusive process based on squared Brownian motion, Dₜ ∼ B²ₜ. For these cases we derive exact expressions for the probability density functions of the maximal positive displacement and of the range of the process xₜ on the time interval ₜ ∈ (0, T).We discuss the asymptotic behaviours of the associated probability density functions, compare these against the behaviour of the corresponding properties of standard Brownian motion with constant diffusivity (Dₜ = D0) and also analyse the typical behaviour of the probability density functions which is observed for a majority of realisations of the stochastic diffusivity process.

 Type species
 Pycnogonum grossipes O. Fabricius, 1780.
 Remarks
 In establishing the genus Nymphon, J.C. Fabricius (1794) included two species (Pycnogonum grossipes O. Fabricius, 1780 and Nymphon hirtum J.C. Fabricius, 1794), without designating a type species. Of these two nominal species eligible to be the type species, N. hirtum was later designated as the type for Chaetonymphon Sars, 1888. This action, however, does not constitute fixation of P. grossipes as the type species of Nymphon, because Article 69.4 of the Code excludes “fixation by elimination” (ICZN 1999). As far as we are aware, no type was fixed for Nymphon before Child’s designation of “ Nymphon grossipes (O. Fabricius, 1780) ” (Child 1998: 35), although this was not in accordance with Recommendation 67B of the Code (ICZN 1999), which states that “the name of a type species should be cited by its original binomen”.

description: A systematic construction is presented of 1/4 BPS operators in N=4 superconformal Yang-Mills theory, using either analytic superspace methods or components. In the construction, the operators of the classical theory annihilated by 4 out of 16 supercharges are arranged into two types. The first type consists of those operators that contain 1/4 BPS operators in the full quantum theory. The second type consists of descendants of operators in long unprotected multiplets which develop anomalous dimensions in the quantum theory. The 1/4 BPS operators of the quantum theory are defined to be orthogonal to all the descendant operators with the same classical quantum numbers. It is shown, to order $g^2$, that these 1/4 BPS operators have protected dimensions.

description: Introduction: While short-term cognitive impairment following electroconvulsive therapy (ECT) is well described and acknowledged, the relationship between ECT and persistent memory impairment, particularly of autobiographical memory, has been controversial. Methods: We describe the case of a 70-year-old consultant neurophysiologist, AW, who developed prominent, selective autobiographical memory loss following two courses of ECT for treatment-resistant depression. Results: His performance on standard measures of IQ, semantic and episodic memory, executive function and mood was normal, while he performed significantly below controls on measures of episodic autobiographical memory. Conclusions: Explanations in terms of mood-related memory loss and somatoform disorder appear unlikely. We relate AW's autobiographical memory impairment, following his ECT, to reports of similar autobiographical memory impairment occurring in the context of epilepsy, and emphasise the importance of using sensitive approaches to AbM assessment.

description: Macroautophagy/autophagy is a conserved degradation pathway in eukaryotes that is required for recycling unwanted intracellular components, maintaining homeostasis, and coping with biotic and abiotic stresses. Pathogens have evolved to subvert autophagic machinery by secreting host cell-entering effector proteins. Here, we provided evidence that an apple autophagy-related gene MdATG8i, activated autophagy and contributed to resistance against Valsa canker caused by Valsa mali (Vm) when being overexpressed in apple. MdATG8i interacted with a plastid elongation factor Tu (MdEF-Tu) which became insoluble and aggregated during Vm infection and was degraded through the autophagy pathway. Intriguingly, we identified a highly-induced effector secreted from Vm, Vm1G-1794, which competitively interacted with MdATG8i, suppressed autophagy, and depleted MdEF-Tu out of MdATG8i complexes. The formation of stable MdEF-Tu aggregates caused by Vm1G-1794 promoted the susceptibility of apple to Vm. Overall, our study demonstrated that MdATG8i contributed to Vm resistance by targeting and degrading MdEF-Tu, and Vm1G-1794 competed with MdEF-Tu to target MdATG8i and prevent MdEF-Tu degradation, thus favoring infection.

description: The impact of age on hallucination-proneness within healthy adult cohorts and its relation to underlying cognitive mechanisms is underexplored. Based on previously researched trends in relation to cognitive ageing, we hypothesised that older and younger adults, when compared to a middle adult age group, would show differential relations between hallucination-proneness and cognitive performance. A mixed methods, between-groups study was conducted with 30 young adults, 26 older adults, and 27 from a “middle adulthood” group. Participants completed a source memory task, jumbled speech task, Launay-Slade hallucination scale, unusual experiences schedule, and control measures of delusion-proneness and attitudes to mental health. Compared to older age-groups, younger participants demonstrated better scores on the source memory task, and reported hearing more words in jumbled speech. Additionally, younger cohorts rated higher on hallucination-proneness and disclosed more unusual experiences on a customised schedule designed to gather further qualitative data. Jumbled speech scores positively correlated with hallucination-proneness scores, particularly for the “middle” age group. Source memory performance unexpectedly correlated positively with hallucination-proneness, although this may be the product of age differences in task performance. Age differences in hallucination-proneness are evident on self-report and cognitive measures. Implications are discussed for potentially non-overlapping cognitive mechanisms underlying hallucination-proneness in non-clinical groups.

In-situ decameter scale experiment

description: The success of geological carbon storage depends on the assurance of a permanent confinement of the injected CO2 in the storage formation at depth. One of the critical elements of the safekeeping of CO2 is the sealing capacity of the caprock overlying the storage formation, despite faults and/or fractures, which may occur in it. In this work, we present an ongoing injection experiment performed in a fault hosted in clay at the Mont Terri underground rock laboratory (NW Switzerland). The experiment aims at improving our understanding on the main physical and chemical mechanisms controlling i) the migration of CO2 through a fault damage zone, ii) the interaction of the CO2 with the neighbouring intact rock, and iii) the impact of the injection on the transmissivity in the fault. To this end, we inject a CO2-saturated saline water in the top of a 3 m think fault in the Opalinus Clay, a clay formation that is a good analogue of common caprock for CO2 storage at depth. The mobility of the CO2 within the fault is studied at decameter scale, by using a comprehensive monitoring system. Our experiment aims to the closing of the knowledge gap between laboratory and reservoir scales. Therefore, an important aspect of the experiment is the decameter scale and the prolonged duration of observations over many months. We collect observations and data from a wide range of monitoring systems, such as a seismic network, pressure temperature and electrical conductivity sensors, fiber optics, extensometers, and an in situ mass spectrometer for dissolved gas monitoring. The observations are complemented by laboratory data on collected fluids and rock samples. Here we show the details of the experimental concept and installed instrumentation, as well as the first results of the preliminary characterization. Analysis of borehole logging allow identifying potential hydraulic transmissive structures within the fault zone. A preliminary analysis of the injection tests helped estimating the transmissivity of such structures within the fault zone, as well as the pressure required to mechanically open such features. The preliminary tests did not record any induced microseismic events. Active seismic tomography enabled a sharp imaging the fault zone. Weniger anzeigen

Melnikov analysis for multi-symplectic PDEs

description: In this work the Melnikov method for perturbed Hamiltonian wave equations is considered in order to determine possible chaotic behaviour in the systems. The backbone of the analysis is the multi-symplectic formulation of the unperturbed PDE and its further reduction to travelling waves. In the multi-symplectic approach two separate symplectic operators are introduced for the spatial and temporal variables, which allow one to generalise the usual symplectic structure. The systems under consideration include perturbations of generalised KdV equation, nonlinear wave equation, Boussinesq equation. These equations are equivariant with respect to abelian subgroups of Euclidean group. It is assumed that the external perturbation preserves this symmetry. Travelling wave reduction for the above-mentioned systems results in a four-dimensional system of ODEs, which is considered for Melnikov type chaos. As a preliminary for the calculation of a Melnikov function, we prove the persistence of a fixed point for the perturbed Poincare map by using Lyapunov-Schmidt reduction. The framework sketched will be applied to the analysis of possible chaotic behaviour of travelling wave solutions for the above-mentioned PDEs within the multi-symplectic approach.

Polar rings of these galaxies were resolved into ~800 and ~430 stellar objects in the B, V and Ic bands, considerable part of which are blue supergiants located in the young stellar complexes. The stellar features in the CM-diagrams are best represented by isochrones with metallicity Z = 0.008. The process of star formation in the polar rings of both galaxies was continuous and the age of the youngest detected stars is about 9 Myr for NGC 2685 and 6.5 Myr for NGC 4650A.

description: The improved results on a direct search for a new X(16.7 MeV) boson which could explain the anomalous excess of $e^+e^-$ pairs observed in the excited 8Be nucleus decays ("Berillium anomaly") are reported. Due to its coupling to electrons, the X boson could be produced in the bremsstrahlung reaction e-Z -> e-ZX by a high-energy beam of electrons incident on active target in the NA64 experiment at the CERN SPS and observed through its subsequent decay into $e^+e^-$ pair. No evidence for such decays was found from the combined analysis of the data samples with total statistics corresponding to 8.4\times 10^{10} electrons on target collected in 2017 and 2018. This allows to set the new limits on the $X$--$e^-$ coupling in the range 1.2 \times 10^{-4} < ε_e < 6.8 \times 10^{-4}, excluding part of the parameter space favored by the Berillium anomaly. We also set new bounds on the mixing strength of photons with dark photons (A') from non-observation of the decay $A' \to e^+e^-$ of the bremsstrahlung A' with a mass below 24 MeV.

description: This paper describes the participation of smallholders in commercial horticultural farming in Kenya and identifies constraints and critical factors that influence their decision to participate in this industry by selling their produce. The study employs panel survey data on smallholder producers of both international (export) and domestic market vegetables and controls for unobserved heterogeneity across farmers. We find that participation of smallholders in both the domestic and export vegetable markets declined and that this trend is associated with weather risks, high costs of inputs and unskilled labour, and erratic vegetable prices, especially in the international market. Different factors are at play in determining a household’s market choice for the commercialisation of vegetables: credit is important only when vegetables are (also) exported, livestock ownership is negatively related to production for the domestic market, and distance to the nearest market town positively related to all pathways of commercialisation, for example.

description: Despite recent breakthroughs, the ability of deep learning and reinforcement learn- ing to outperform traditional approaches to control physically embodied robotic agents remains largely unproven. To help bridge this gap, we have developed the “AI Driving Olympics” (AI-DO), a competition with the objective of evaluating the state-of-the-art in machine learning and artificial intelligence for mobile robotics. Based on the simple and well specified autonomous driving and navigation en- vironment called “Duckietown,” AI-DO includes a series of tasks of increasing complexity—from simple lane-following to fleet management. For each task, we provide tools for competitors to use in the form of simulators, data logs, code templates, baseline implementations, and low-cost access to robotic hardware. We evaluate submissions in simulation online, on standardized hardware environments, and finally at the competition events. We have held successful AI-DO competitions at NeurIPS 2018 and ICRA 2019, and will be holding AI-DO 3 at NeurIPS 2020. Together, these competitions highlight the need for better benchmarks, which are lacking in robotics, as well as improved mechanisms to bridge the gap between simulation and reality.

Inertial effects of self-propelled particles: from active Brownian to active Langevin motion

Year: 2019
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Active particles which are self-propelled by converting energy into mechanical motion represent an expanding research realm in physics and chemistry. For micron-sized particles moving in a liquid ("microswimmers"), most of the basic features have been described by using the model of overdamped active Brownian motion. However, for macroscopic particles or microparticles moving in a gas, inertial effects become relevant such that the dynamics is underdamped. Therefore, recently, active particles with inertia have been described by extending the active Brownian motion model to active Langevin dynamics which include inertia. In this perspective article recent developments of active particles with inertia ("microflyers") are summarized both for single particle properties and for collective effects of many particles. There include: inertial delay effects between particle velocity and self-propulsion direction, tuning of the long-time self-diffusion by the moment of inertia, effects of fictitious forces in non-inertial frames, and the influence of inertia on motility-induced phase separation. Possible future developments and perspectives are also proposed and discussed.
Prepotential and Instanton Corrections in N=2 Supersymmetric SU(N_1)xSU(N_2) Yang Mills Theories

description: In this paper we analyse the non-hyperelliptic Seiberg-Witten curves derived from M-theory that encode the low energy solution of N=2 supersymmetric theories with product gauge groups. We consider the case of a SU(N_1)xSU(N_2) gauge theory with a hypermultiplet in the bifundamental representation together with matter in the fundamental representations of SU(N_1) and SU(N_2). By means of the Riemann bilinear relations that hold on the Riemann surface defined by the Seiberg--Witten curve, we compute the logarithmic derivative of the prepotential with respect to the quantum scales of both gauge groups. As an application we develop a method to compute recursively the instanton corrections to the prepotential in a straightforward way. We present explicit formulas for up to third order on both quantum scales. Furthermore, we extend those results to SU(N) gauge theories with a matter hypermultiplet in the symmetric and antisymmetric representation. We also present some non-trivial checks of our results.

description: Past research reveals important connections between meditative practices and compassion. Most studies, however, focus on the effects of one type of meditation (vs. a no-intervention control) on a single expression of compassion (e.g. offering a seat) towards a relatable target (e.g. a person on crutches), without exploring possible mechanisms. Hence, few studies include different types of meditation, active controls, multiple ways to express compassion, unrelatable targets, and potential mediators. To this end, the present study compared the effects of mindfulness meditation with those of compassion meditation on different expressions of compassion towards a convicted murderer. Seventy-four participants were randomly assigned to a mindfulness meditation, compassion meditation, or active control class, or a no-class control. After an 8-week programme, we assessed compassion by giving participants the option of fulfilling a murderer’s request that they write him and then coding those letters for empathy, sympathy, forgiveness, and optimism. Participants in the compassion meditation class wrote more optimistic letters compared to participants in the other three conditions, in part because they valued positivity more. No statistically significant differences emerged for the other expressions of compassion. We discuss the implications of these findings for our understanding of how meditation increases compassion towards unrelatable targets.

description: Defining quantum dots in semiconductor based heterostructures is an essential step in initializing solid-state qubits. With growing device complexity and increasing number of functional devices required for measurements, a manual approach to finding suitable gate voltages to confine electrons electrostatically is impractical. Here, we implement a two-stage device characterization and dot-tuning process which first determines whether devices are functional and then attempts to tune the functional devices to the single or double quantum dot regime. We show that automating well established manual tuning procedures and replacing the experimenter's decisions by supervised machine learning is sufficient to tune double quantum dots in multiple devices without pre-measured input or manual intervention. The quality of measurement results and charge states are assessed by four binary classifiers trained with experimental data, reflecting real device behaviour. We compare and optimize eight models and different data preprocessing techniques for each of the classifiers to achieve reliable autonomous tuning, an essential step towards scalable quantum systems in quantum dot based qubit architectures.
On the Meaning of the String-Inspired Noncommutativity and its Implications

description: We propose an alternative interpretation for the meaning of noncommutativity of the string-inspired field theories and quantum mechanics. Arguments are presented to show that the noncommutativity generated in the stringy context should be assumed to be only between the particle coordinate observables, and not of the spacetime coordinates. Some implications of this fact for noncomutative field theories and quantum mechanics are discussed. In particular, a consistent interpretation is given for the wavefunction in quantum mechanics. An analysis of the noncommutative theories in the Schrödinger formulation is performed employing a generalized quantum Hamilton-Jacobi formalism. A formal structure for noncommutative quantum mechanics, richer than the one of noncommutative quantum field theory, comes out. Conditions for the classical and commutative limits of these theories have also been determined and applied in some examples.

description: We study some properties of the extended phase space of a quantum-corrected Schwarzschild black hole surrounded by a perfect fluid. In particular we demonstrate that, due to the quantum correction, there exist first and second order phase transitions for a certain range of the state parameter of the perfect fluid, and we explicitly analyze some cases. Besides that, we describe the efficiency of this system as a heat engine and the effect of quantum corrections for different surrounding fluids.

description: Lonely individuals show increased social monitoring and heightened recognition of negative facial expressions. The current study investigated whether this pattern extends to other nonverbal modalities by examining associations between loneliness and the recognition of vocal emotional expressions. Youth, ages 11–18 years (n = 122), were asked to identify the intended emotion in auditory portrayals of basic emotions (anger, disgust, fear, happiness, sadness) and social expressions (friendliness, meanness). Controlling for social anxiety, age, and gender, links between loneliness and recognition accuracy were emotion-specific: loneliness was associated with poorer recognition of fear, but better recognition of friendliness. Lonely individuals’ motivation to avoid threat may interfere with the recognition of fear, but their attunement to affiliative cues may promote the identification of friendliness in affective prosody. Monitoring for social affiliation cues in others’ voices might represent an adaptive function of the reconnection system in lonely youth, and be a worthy target for intervention.

description: We consider matching from SCETI, which includes ultrasoft and collinear particles, onto SCETII with soft and collinear particles at one loop. Keeping the external fermions off their mass shell does not regulate all IR divergences in both theories. We give a new prescription to regulate infrared divergences in SCET. Using this regulator, we show that soft and collinear modes in SCETII are sufficient to reproduce all the infrared divergences of SCETI. We explain the relationship between IR regulators and an additional mode proposed for SCETII.

description: We prove that a class of partially hyperbolic attractors introduced by Castro and Nascimento have unique equilibrium states for natural classes of potentials. We also show if the attractors are $C^2$ and have invariant stable and centerunstable foliations, then there is a unique equilibrium state for the geometric potential and its 1-parameter family. We do this by applying general techniques developed by Climenhaga and Thompson.
