description: As galactic cosmic rays propagate through the turbulent plasma environment within the heliosphere, they undergo a process of diffusion, drift and energy loss, leading to a notable reduction in their flux. This is the solar modulation impact. Recently, the cosmic-ray experiment AMS-02 published daily fluxes of proton and Helium for the period from May 20, 2011 to October 29, 2019 in the rigidity interval from about 1 to 100 GV, exhibiting fine time structures that correlate with solar wind properties on daily basis. In this work, we employ three different modified force field approximation models to fit the data. By fitting to the daily proton and Helium fluxes, we get the time series of solar modulation potential. We find good agreement of data and model predictions for both proton and Helium with the same parameters in two modified force field approximation models. The results in this study verify that the modified FFA model is a valid parametrization of the GCR spectrum also at daily time scales.

description: Accurate localization is a critical component of mobile autonomous systems, especially in Global Navigation Satellite Systems (GNSS)-denied environments where traditional methods fail. In such scenarios, environmental sensing is essential for reliable operation. However, approaches such as LiDAR odometry and Simultaneous Localization and Mapping (SLAM) suffer from drift over long distances, especially in the absence of loop closures. Map-based localization offers a robust alternative, but the challenge lies in creating and georeferencing maps without GNSS support. To address this issue, we propose a method for creating georeferenced maps without GNSS by using publicly available data, such as building footprints and surface models derived from sparse aerial scans. Our approach integrates these data with onboard LiDAR scans to produce dense, accurate, georeferenced 3D point cloud maps. By combining an Iterative Closest Point (ICP) scan-to-scan and scan-to-map matching strategy, we achieve high local consistency without suffering from long-term drift. Thus, we eliminate the reliance on GNSS for the creation of georeferenced maps. The results demonstrate that LiDAR-only mapping can produce accurate georeferenced point cloud maps when augmented with existing map priors.

description: The plate boundary between the American and Eurasian plates runs in southwest Iceland along a 5-10 km wide seismicity zone on the Reykjanes Peninsula. There, tectonic spreading events take place as continuous seismic release and seismic episodes (swarms and individual large events) with recurrence interval of about 40 years and volcanic episodes at intervals of 800-1000 years. The crust in Reykjanes is, therefore, particularly thin and hot and geothermal energy is currently harnesses in two areas on the western part of the peninsula in Reykjanes and Svartsengi.

Since January 2020, earthquake swarms with larger events up to M5.6 have been occurring frequently over the entire Reykjanes Peninsula, accompanied by unusual uplift (up to 12 cm) and subsidence cycles in the Svartsengi-Eldvörp fissure swarm. This raises the question whether we might be at the beginning of a new volcanic episode. In order to classify such processes at an early stage, multidisciplinary geophysical measurements are particularly valuable.

The Icelandic Meteorological Office (IMO), University of Iceland as well as ISOR and several partners responded immediately after the unrest began. As soon as January 2020, GFZ proposed a rapid response field campaign (MAGIC: MultidisciplinAry imaGIng and Characterization of the magma/fluid reservoir beneath Svartsengi). Only one week after the uplift start and first earthquake swarm, we connected a Distributed Acoustic Sensing interrogator to a 21 km long telecommunication fibre optic cable which crosses the uplift and swarm area. In addition, while we complied to strict constraints due to the Covid-19 pandemic, the rapid response activities comprised deployment of several additional sensors including broadband seismology, rotational seismology and we performed repeated surveys including gas-, gravity-, electromagnetic-, airborne and ground magnetic- measurements.

We present preliminary results from various techniques and discuss their role in discriminating different scenarios aiming at explaining the magma-tectonic unrest phase. In particular, we analyze how the combination of airborne snapshots of ground morphology can be combined with the high temporal and spatial resolution deformation fields along the fibre optic cable.

description: Virtual Reality (VR) is an exciting new consumer technology which offers an immersive audio-visual experience to users through which they can navigate and interact with a digitally represented 3D space (i.e., a virtual world) using a headset device. By (visually) transporting users from the real or physical world to exciting and realistic virtual spaces, VR systems can enable true-to-life and more interactive versions of traditional applications such as gaming, remote conferencing, social networking and virtual tourism. However, as with any new consumer technology, VR applications also present significant user-privacy challenges. This paper studies a new type of privacy attack targeting VR users by connecting their activities visible in the virtual world (enabled by some VR application/service) to their physical state sensed in the real world. Specifically, this paper analyzes the feasibility of carrying out a de-anonymization or identification attack on VR users by correlating visually observed movements of users' avatars in the virtual world with some auxiliary data (e.g., motion sensor data from mobile/wearable devices held by users) representing their context/state in the physical world. To enable this attack, this paper proposes a novel framework which first employs a learning-based activity classification approach to translate the disparate visual movement data and motion sensor data into an activity-vector to ease comparison, followed by a filtering and identity ranking phase outputting an ordered list of potential identities corresponding to the target visual movement data. Extensive empirical evaluation of the proposed framework, under a comprehensive set of experimental settings, demonstrates the feasibility of such a de-anonymization attack.

description: Die Besitzlosigkeit bzw. Armut der Priester und der Verzicht der Kirche auf jede politische Herrschaft waren eine der wesentlichsten Forderungen der hussitischen Bewegung und Inhalt des vierten Prager Artikels (1421). Auf dem Konzil zu Basel verteidigte der englische Theologe Peter Payne dieses Programm in einem theologischen Disput gegen den spanischen Kanonisten Juan Palomar. Diese Arbeit analysiert in ihrem Hauptteil die Rede Paynes vor dem Konzil: Ihre Struktur, die verwendete Begrifflichkeit und die Argumentation Paynes. In der Einleitung wird die Quellenlage behandelt: Alle Reden aus Basel wurden vollständig überliefert (die Rede Paynes in einer einzigen Handschrift) und später ediert. Das zweite Kapitel beschäftigt sich mit dem „Egerer Richter“ (1432), in dem die hermeneutischen Grundlagen und die Regeln für den Disput formuliert werden. Im dritten Kapitel wird die Genese des vierten Prager Artikels skizziert: Die Reformstimmung in Böhmen in der zweiten Hälfte des 14. Jahrhunderts, der entscheidende Einfluss des Wyclifismus auf das theologische Denken (nicht nur) an der Prager Universität. Die Positionen von Johannes Wyclif fanden Eingang auch in das theologische Werk von Johannes Hus, der genauso wie Wyclif die Kritik der angeblichen Missstände in der Kirche (die Simonie) mit der Forderung einer umfassenden Kirchenreform (Rückkehr zum Evangelium und zur Praxis der ecclesia primitiva) verbunden hat. Bei der eigentlichen Analyse der Rede Paynes auf dem Konzil (4. Kapitel) wird zunächst auf die wichtigsten Begriffe eingegangen: Die Definitionen und Begrifflichkeiten stammen ursprünglich vor allem aus dem Kontext des sog. theoretischen Armutsstreites (z.B. Wilhelm von Ockham) und Payne adaptiert sie mit Hilfe von Wyclif auf den ganzen Weltklerus. Als für die Diskussion äußerst problematisch erweist sich der Gesetzesbegriff Paynes: Die Heilige Schrift (in ihrem wörtlichen Sinn) soll der höchste Schiedsrichter sein und steht daher über der Kirche. Das Konzil verstand sich dagegen als der höchste Repräsentant der unfehlbaren Kirche, in der die Schrift normativ ausgelegt werden darf bzw. soll. Seine Thesen begründet Payne hauptsächlich mit einigen Stellen aus der Bibel und mit verschiedenen Zitaten der Kirchenväter (vor allem Klemens von Rom, Hieronymus, Augustinus und Bernhard von Clairvaux). Diese werden im 5. Kapitel genauer analysiert und anschließend wird im 6. Kapitel auch die replica von Juan Palomar bzw. ihre Argumentation kurz vorgestellt.

description: One of the greatest challenges facing polymeric cardiovascular devices is the issue of hemocompatibility. Devices such as polymeric heart valves potentially offer improved mechanical properties and quality of life compared to their animal tissue counterparts. However, they are still strongly limited by problematic interactions with blood. The reduction of platelet adhesion, thrombogenicity, and calcification have been addressed in a variety of surface and bulk modification methods, generally by increasing the hydrophilic character of polymers. However, most hydrophilization processes – oxygen plasma in particular – tend to offer limited longevity. The crystallinity of polymers has previously been observed to influence the extent of platelet adhesion, though the underlying mechanisms for this phenomenon are not clear. In this research, we report on the effect of crystallinity on hemolysis, thrombogenicity, and platelet adhesion in PEEK surfaces. By tailoring the bulk crystallinity, we demonstrate changes in the surface chemical composition and propose a potential strategy to achieve longer term surface modification for improved hemocompatibility. Additionally, we explore the influence of crystallinity on the mechanical properties of thin PEEK films, establishing the multi-dimensional impact of polymer crystallinity. The results shown here may have implications for the design of polymeric cardiovascular devices and considerations that should be taken during material selection.

description: The spectra of galactic cosmic rays (GCRs) contain crucial information about their origin and propagation through the interstellar medium. When GCRs reach Earth, they are significantly influenced by the solar wind and the heliospheric magnetic field, a phenomenon known as solar modulation. This effect introduces time-dependent variations in GCR fluxes. The AMS-02 experiment has released time-dependent flux data for protons, electrons, and positrons, revealing clear correlations with solar modulation. Studies suggest that cosmic rays with the same charge, such as protons and helium nuclei, exhibit similar/same solar modulation parameters. In this work, we derive the LIS for protons and positrons under the assumption of a common solar modulation potential, using data from Voyager 1 and a 7-year average from AMS-02. Similarly, the LIS for antiprotons and electrons is derived by assuming they are governed by a separate solar modulation potential. We demonstrate that the time-dependent fluxes of positrons and protons can be accurately modeled using the same set of solar modulation parameters within a modified force-field approximation framework. Based on this, we predict the time-dependent fluxes of antiprotons using the corresponding electron flux data.

Continuous signal sparse encoding using analog neuromorphic variability

Subjects: subject: Neural and Evolutionary Computing (cs.NE)
subject: FOS: Computer and information sciences

description: Achieving fast and reliable temporal signal encoding is crucial for low-power, always-on systems. While current spike-based encoding algorithms rely on complex networks or precise timing references, simple and robust encoding models can be obtained by leveraging the intrinsic properties of analog hardware substrates. We propose an encoding framework inspired by biological principles that leverages intrinsic neuronal variability to robustly encode continuous stimuli into spatio-temporal patterns, using at most one spike per neuron. The encoder has low model complexity, relying on a shallow network of heterogeneous neurons. It relies on an internal time reference, allowing for continuous processing. Moreover, stimulus parameters can be linearly decoded from the spiking patterns, granting fast information retrieval. Our approach, validated on both analog neuromorphic hardware and simulation, demonstrates high robustness to noise, spike jitter, and reduced heterogeneity. Consistently with biological observations, we observed the spontaneous emergence of patterns with stereotyped spiking order. The proposed encoding scheme facilitates fast, robust and continuous information processing, making it well-suited for low-power, low-latency processing of temporal data on analog neuromorphic substrates.

description: This paper presents a novel approach for the safe control design of systems with parametric uncertainties in both drift terms and control-input matrices. The method combines control barrier functions and adaptive laws to generate a safe controller through a nonlinear program with an explicitly given closed-form solution. The proposed approach verifies the non-emptiness of the admissible control set independently of online parameter estimations, which can ensure the safe controller is singularity-free. A data-driven algorithm is also developed to improve the performance of the proposed controller by tightening the bounds of the unknown parameters. The effectiveness of the control scheme is demonstrated through numerical simulations.

description: Using the path integral approach, we derive the low energy interactions between axions and electromagnetic field that arise in models with heavy dyons charged under a spontaneously broken global axial $U(1)$ symmetry. Hence, we obtain generic axion-Maxwell equations relevant for experimental searches. We find that the structure of the axion Maxwell equations could be significantly different compared to what is normally assumed in the literature, as the derived equations feature new axion-dependent terms including CP-violating ones. The new terms can reconcile the Peccei-Quinn solution to the strong CP problem with astrophysical axion hints, as well as give unique signatures in light-shining-through-wall and haloscope experiments. Moreover, via the latter signatures, these experiments can indirectly probe the existence of heavy dyons.

description: Continual learning research has shown that neural networks suffer from catastrophic forgetting "at the output level", but it is debated whether this is also the case at the level of learned representations. Multiple recent studies ascribe representations a certain level of innate robustness against forgetting -- that they only forget minimally in comparison with forgetting at the output level. We revisit and expand upon the experiments that revealed this difference in forgetting and illustrate the coexistence of two phenomena that affect the quality of continually learned representations: knowledge accumulation and feature forgetting. Taking both aspects into account, we show that, even though forgetting in the representation (i.e. feature forgetting) can be small in absolute terms, when measuring relative to how much was learned during a task, forgetting in the representation tends to be just as catastrophic as forgetting at the output level. Next we show that this feature forgetting is problematic as it substantially slows down the incremental learning of good general representations (i.e. knowledge accumulation). Finally, we study how feature forgetting and knowledge accumulation are affected by different types of continual learning methods.

title: Homines novi - eine empirisch-theoretische Kritik an Konzepten und Messungen sozialer Herkunft unter Studierenden
Creators: name: Hartl, Jakob
Year: 2012

description: Die Bildungsexpansion der zweiten Hälfte des 20sten Jahrhunderts hat zu einem starken Anstieg an AkademikerInnen in den meisten (west-)europäischen Gesellschaften geführt. Beschreibungen der sozialen Zusammensetzung von Studierendenpopulationen tragen dieser Entwicklung aber nicht Rechnung, sondern verharren in den Kategorien „AkademikerIn“ vs. „Nicht-AkademikerIn“. Bei voranschreitender Höherqualifizierung ist aber davon auszugehen, dass die alten Kategorien die soziale Herkunft der Studierenden immer weniger adäquat abbilden. Um diese Differenzierung aufzuzeigen, muss das „Was?“ und „Wie?“ des Studierens in den Mittelpunkt gerückt werden. Die Hypothese einer praxistheoretischen Kritik an den a priori gefassten Kategorien sozialer Herkunft ist folglich, dass sich in der sozialen Praxis der Studierenden die Wirkmächtigkeit ihrer sozialen Herkunft abbildet, wodurch Rückschlüsse auf die Wirkmechanismen sozialer Herkunft möglich werden. Diese Hypothese wurde mittels K-Means-Clusteranalyse über ein Sub-Sample von über 15.000 Studierenden aus der österreichischen Studierenden-Sozialerhebung 2009 geprüft. In die Konstruktion der Cluster flossen Variablen zum Studierverhalten (Studienrichtung, Auslandserfahrung, Zweitstudium) ebenso ein wie Variablen zur sozio-ökonomischen Situation (Finanzierung, Wohnsituation, Erwerbsausmaß) und Skalenvariablen, die etwa Schwierigkeiten der Studierenden im Studienalltag, Studienmotive oder Employability-Strategien abbilden. Die Untersuchung der Cluster auf ihre soziale Zusammensetzung zeigt deutlich, wie sich die Studierenden in ihrem Studierverhalten herkunftsabhängig differenzieren, aber auch, dass diese Differenzen nicht einfach entlang der herkömmlichen Trennlinien sozialer Herkunft verlaufen, sondern letztere sich in den gebildeten Clustern unterschiedlich, z.B. abhängig vom Hochschulsektor und dem Geschlecht der Studierenden, manifestiert. Damit kann die Zugehörigkeit zu den jeweiligen Clustern Ausgangspunkt für eine praxistheoretische Kritik und Innovation für die Messung sozialer Herkunft unter Studierenden sein.

The review starts off with a pedagogical introduction on the modified bulk-boundary correspondence, the synergy and hybridization of NHSE and band topology in higher dimensions, as well as, the associated topology on the complex energy plane such as spectral winding topology and spectral graph topology. Following which, emerging topics are introduced such as non-Hermitian criticality, dynamical NHSE phenomena, and the manifestation of NHSE beyond the traditional linear non-interacting crystal lattices, particularly its interplay with quantum many-body interactions. Finally, we survey the recent demonstrations and experimental proposals of NHSE.

description: This paper introduces a noise-tolerant computing method for over-the-air computation (AirComp) aimed at weighted averaging, which is critical in various Internet of Things (IoT) applications such as environmental monitoring. Traditional AirComp approaches, while efficient, suffer significantly in accuracy due to noise enhancement in the normalization by the sum of weights. Our proposed method allows nodes to adaptively truncate their weights based on the channel conditions, thereby enhancing noise tolerance. Applied to distributed Gaussian process regression (D-GPR), the method facilitates low-latency, low-complexity, and high-accuracy distributed regression across a range of signal-to-noise ratios (SNRs). We evaluate the performance of the proposed method in a radio map construction problem, which involves visualizing the radio environment based on limited sensing information and spatial interpolation. Numerical results show that our approach maintains computational accuracy in low-SNR scenarios and achieves performance close to ideal conditions in high SNR environments. In addition, a case study targeting a federated learning (FL) system demonstrates the potential of our proposed method in improving model aggregation accuracy, not only for D-GPR but also for FL systems.

description: Countless studies have demonstrated ways in which forests and trees affect catchment water balances. Water balance differences between forested and non-forested landscapes are often attributed to characteristics related to trees’ ability to take up and transpire water, as well as their ability to intercept precipitation. However, another potentially important characteristic of forests that has been largely overlooked in hydrologic studies is the retention and accumulation of debris, litter and deadwood on the forest floor. Here we leverage ongoing measurements at the new hillslope laboratory “Waldlabor” in Zurich, Switzerland, where water retention in forest litter, deadwood and the top soil layer has been investigated using frequent field campaigns and innovative new sensing techniques.

Several approaches were used to determine the maximum storage capacity as well as the storage dynamics of different types and layers of litter. In-lab saturation experiments revealed the maximum storage capacity of various litter types (i.e., leaf and needle litter). Those values were also supported with field pre- and post- rainfall sampling campaigns to determine in-situ litter storage dynamics, as well as to understand the interplay between litter interception and soil-water recharge. Importantly, recharge was often substantially smaller at plots with litter, compared to those without litter. The storage and water retention capacity of deadwood samples was measured in the field by logging the diurnal differences in deadwood weight over a six month period. Dew and fog deposition during the night led to larger water availability for evaporation during the day. We measured increased humidity at sensors in the forest at 1 and 3m heights respectively, compared to the humidity outside the forest. Daily weight measurements over eight weeks of 40 deadwood pieces at our forest site revealed differences in the storage capacity depended on the degree of decomposition. Additionally, we found that water stored in forest floor spruce cones (daily measurements of 20 pieces) actively contributed to evaporation fluxes.

The combination of continuous sensor measurements (soil moisture, deadwood water content), field measurements (litter and deadwood grab samples) as well as laboratory work (saturation experiments) revealed the water storage and retention capacity of litter and deadwood in a typical temperate mixed forest and their contribution to evaporation. These measurements are one component of the new ETH Zürich “Waldlabor” research infrastructure, which also includes measurements of precipitation, xylem water, soil water, groundwater, and discharge amounts, isotope ratios, and other chemical characteristics.

description: Managing the explosion of data from the edge to the cloud requires intelligent supervision such as fog node deployments, which is an essential task to assess network operability. To ensure network operability, the deployment process must be carried out effectively in terms of two main factors: connectivity and coverage. The network connectivity is based on fog node deployment which determines the physical topology of the network while the coverage determines the network accessibility. Both have a significant impact on network performance and guarantee the network QoS. Determining an optimum fog node deployment method that minimizes cost, reduces computation and communication overhead, and provides a high degree of network connection coverage is extremely hard. Therefore, maximizing coverage as well as preserving network connectivity is a non-trivial problem. In this paper, we proposed a fog deployment algorithm that can effectively connect the fog nodes and cover all edge devices. Firstly, we formulate fog deployment as an instance of multi-objective optimization problems with a large search space. Then, we leverage Marine Predator Algorithm (MPA) to tackle the deployment problem and prove that MPA is well-suited for fog node deployment due to its rapid convergence and low computational complexity compared to other population-based algorithms. Finally, we evaluate the proposed algorithm on a different benchmark of generated instances with various fog scenario configurations. The experimental results demonstrate that our proposed algorithm is capable of providing very promising results when compared to state-of-the-art methods for determining an optimal deployment of fog nodes.

description: I consider QCD$_2$ in the $N_c \to \infty$ limit at fixed $g^2N_c$. The derivation starts from equal-time $q\bar q$ bound states in coordinate space and temporal ($A^0=0$) gauge, avoiding the use of quark and gluon propagators. The wave function is given analytically by a $_1F_1$ function with an explicit frame dependence. In the infinite momentum frame the Fourier transformed wave function satisfies the 't~Hooft equation, however with contributions also from quarks with negative kinetic energy. Such contributions are present also in the rest frame, and do not vanish under boosts.

description: Time-bin (TB) and energy-time (ET) entanglement are crucial resources for long-distance quantum information processing. Recently, major efforts have been made to produce compact high-quality sources of TB/ET entangled photons based on solid-state integrated technologies. However, these attempts failed to close the so-called "post-selection loophole". Here, we present an integrated photonic general Bell-test chip for genuine (i.e., free of the post-selection loophole) TB and ET entanglement certification. We report a violation of a Bell inequality by more than 10 standard deviations using our device based on the "hug" interferometric scheme. The experiment also demonstrates that the hug scheme, previously exploited for ET entanglement, can also be used for genuine TB entanglement.

description: Drones have been widely used in various services, such as delivery and surveillance. Authentication forms the foundation of the security of these services. However, drones are expensive and may carry important payloads. To avoid being captured by attackers, drones should keep a safe distance from the verifier before authentication succeeds. This makes authentication methods that only work in very close proximity not applicable. Our work leverages drone noises for authentication. While using sounds for authentication is highly usable, how to handle various attacks that manipulate sounds is an \emph{unresolved challenge}. It is also unclear how to ensure robustness under various environmental sounds. Being the first in the literature, we address the two major challenges by exploiting unique characteristics of drone noises. We thereby build an authentication system that does \emph{not} rely on any drone sound fingerprints, keeps resilient to attacks, and is robust under environmental sounds. An extensive evaluation demonstrates its security and usability.

description: Quantum error correction (QEC) is theoretically capable of achieving the ultimate estimation limits in noisy quantum metrology. However, existing quantum error-correcting codes designed for noisy quantum metrology generally exploit entanglement between one probe and one noiseless ancilla of the same dimension, and the requirement of noiseless ancillas is one of the major obstacles to implementing the QEC metrological protocol in practice. Here we successfully lift this requirement by explicitly constructing two types of multi-probe quantum error-correcting codes, where the first one utilizes a negligible amount of ancillas and the second one is ancilla-free. Specifically, we consider Hamiltonian estimation under Markovian noise and show that (i)~when the Heisenberg limit (HL) is achievable, our new codes can achieve the HL and its optimal asymptotic coefficient; (ii)~when only the standard quantum limit (SQL) is achievable (even with arbitrary adaptive quantum strategies), the optimal asymptotic coefficient of the SQL is also achievable by our new codes under slight modifications.

title: Nicht-Direktivität in der Arbeit mit verhaltensauffälligen Kindern und Jugendlichen
Creators: name: Blumer, Bettina
Year: 2012

description: Das Krankheitsbild der Verhaltensaufälligkeiten bei Kindern und Jugendlichen wird seit Jahren intensiv behandelt. Nichts desto trotz kann aufgrund der unterschiedlichsten Symptome, Auswirkungen, Häufigkeitserscheinungen und Intensitäten keine einheitliche Definition gegeben werden, die all diese Bereiche umfasst. Fest steht jedoch, dass bei dem Versuch einer Bezeichnung des Krankheitsbildes Bewusstsein dafür geschaffen werden soll, das von der Gesellschaft als auffällig bezeichnete Verhalten als Teil des Individuums zu sehen. Das Verhalten definiert nicht den Heranwachsenden, sondern ist ein Teil von ihm und sollte aus diesem Grund auch in diesem Sinne Platz in der Definition finden. In vorliegender Arbeit wird daher von Kindern und Jugendlichen mit Verhaltensauffälligkeiten gesprochen. Weiters wird durch die intensive Auseinandersetzung eben genannter Aspekte mit Blick auf die humanistische Pädagogik, die von einer positiven Natur des Menschen und der ihr inhärenten Tendenz der Weiterentwicklung des Selbst ausgeht, tiefergehend auf den nicht-direktiven Ansatz nach Carl Rogers in Bezug genommen. Auf Basis mehrerer problemzentriert-geführter Interviews mit Sozialpädagoginnen und den daraus gewonnenen Daten werden die Möglichkeiten und Chancen einer Umsetzung des nicht-direktiven Ansatzes mit Heranwachsenden mit Verhaltensauffälligkeiten beleuchtet. Der Einsatz nicht-direktiver Gesprächsführung ist im sozialpädagogischen Setting der Wohngemeinschaft nur bedingt einsetzbar, sodass zusammenfassend gesagt werden kann, dass einige nicht-direktive Aspekte Einzug in die sozialpädagogische Arbeit mit Kindern und Jugendlichen mit Verhaltensauffälligkeiten genommen hat, diese jedoch in modifizierter Form, wie Rogers dies auch propagierte, umgesetzt werden.

description: Leaf phenology is key for regulating total growing season mass and energy fluxes. Long-term temporal trends towards earlier leaf unfolding are observed across Northern Hemisphere forests. Phenological dates also vary between years, whereby end-of-season (EOS) dates correlate positively with start-of-season (SOS) dates and negatively with growing season total net CO2 assimilation (Anet). These associations have been interpreted as the effect of a constrained leaf longevity or of premature carbon (C) sink saturation - with far-reaching consequences for long-term phenology projections under climate change and rising CO2. Here, we use multi-decadal ground and remote-sensing observations to show that the relationships between Anet and EOS are opposite at the interannual and the decadal time scales. A decadal trend towards later EOS persists in parallel with a trend towards increasing Anet - in spite of the negative Anet-EOS relationship at the interannual scale. This indicates that acclimation of phenology has enabled plants to transcend a constrained leaf longevity or premature C sink saturation over the course of several decades, leading to a more effective use of available light and a sustained extension of the vegetation CO2 uptake season over time.
