description: For a locally compact quantum group $\mathbb{G}$, consider the convolution action of a quantum probability measure $μ$ on $L_\infty(\mathbb{G})$. As shown by Junge--Neufang--Ruan, this action has a natural extension to a Markov map on $\mathcal{B}(L_2(\mathbb{G}))$. We prove that the Poisson boundary of the latter can be realized concretely as the von Neumann crossed product of the Poisson boundary associated with $μ$ under the action of $\mathbb{G}$ induced by the coproduct. This yields an affirmative answer, for general locally compact quantum groups, to a problem raised by Izumi (2004) in the commutative situation, in which he settled the discrete case, and unifies earlier results of Jaworski, Neufang and Runde.

description: Background: Cerebral palsy (CP) is the most common motor disability in children, which is instigated by damage to the developing brain that affects the ability to control the muscles. The main types of CP are spastic CP, dyskinesia CP and mixed CP. The aim of this work was to estimate the concentrations of complete blood count (CBC), erythrocytic sedimentation rate (ESR), C-reactive protein (CRP), brain-derived neurotrophic factor (BDNF), and tumor necrosis factor-α (TNF-α) in children with CP compared to the control group. Methods: A total of 75 Egyptian children were enrolled in this study, 45 had CP and 30 were controls. CBC, ESR, CRP, BDNF, and TNF-α were assessed. Results: The ESR, CRP and TNF-α levels showed statistically significant increases in cases compared to controls. While the neutrophil/lymphocyte ratio and the BDNF levels were significantly lower in CP compared with the controls. When comparing the different groups of CP with each other; there were no significant differences. Regarding the correlation of BDNF and different studied parameters, our study showed a positive correlation between BDNF and TNF levels only within the group with spastic CP. Conclusions: BDNF may be considered as a biomarker or treatment target for CP to avoid further complications as still there is insufficient progress in the prediction, early diagnosis, treatment, and prevention of CP. Furthermore, searching for new strategies to increase BDNF levels may open a new opportunity for the treatment of CP.

description: The present paper defines ST-structures (and an extension of these, called STC-structures). The main purpose is to provide concrete relationships between highly expressive concurrency models coming from two different schools of thought: the higher dimensional automata, a \textit{state-based} approach of Pratt and van Glabbeek; and the configuration structures and (in)pure event structures, an \textit{event-based} approach of van Glabbeek and Plotkin. In this respect we make comparative studies of the expressive power of ST-structures relative to the above models. Moreover, standard notions from other concurrency models are defined for ST(C)-structures, like steps and paths, bisimilarities, and action refinement, and related results are given. These investigations of ST(C)-structures are intended to provide a better understanding of the \textit{state-event duality} described by Pratt, and also of the (a)cyclic structures of higher dimensional automata.

description: The robotic 2m Liverpool Telescope, based on the Canary island of La Palma, has a diverse instrument suite and a strong track record in time domain science, with highlights including early time photometry and spectra of supernovae, measurements of the polarization of gamma-ray burst afterglows, and high cadence light curves of transiting extrasolar planets. In the next decade the time domain will become an increasingly prominent part of the astronomical agenda with new facilities such as LSST, SKA, CTA and Gaia, and promised detections of astrophysical gravitational wave and neutrino sources opening new windows on the transient universe. To capitalise on this exciting new era we intend to build Liverpool Telescope 2: a new robotic facility on La Palma dedicated to time domain science. The next generation of survey facilities will discover large numbers of new transient sources, but there will be a pressing need for follow-up observations for scientific exploitation, in particular spectroscopic follow-up. Liverpool Telescope 2 will have a 4-metre aperture, enabling optical/infrared spectroscopy of faint objects. Robotic telescopes are capable of rapid reaction to unpredictable phenomena, and for fast-fading transients like gamma-ray burst afterglows. This rapid reaction enables observations which would be impossible on less agile telescopes of much larger aperture. We intend Liverpool Telescope 2 to have a world-leading response time, with the aim that we will be taking data with a few tens of seconds of receipt of a trigger from a ground- or space-based transient detection facility. We outline here our scientific goals and present the results of our preliminary optical design studies.

description: Kundenorientierung ist in aller Munde. Erfolgsfaktoren zu diesem Modell sind bisher aber kaum empirisch untersucht worden. Dadurch wird Kundenorientierung in der Praxis mehr eine Art Glaubensrichtung als ein fundiertes Managementmodell mit klaren Wirkungsbeziehungen. In dieser Studie werden Erfolgsfaktoren der Kundenorientierung untersucht. Dies erfolgt auf der Basis der Einschätzung von Mitarbeitenden in Bezug auf das eigene Unternehmen. Dieser Ansatz hat eine gewisse Limitierung, weil nur Elemente als Erfolgsfaktoren identifiziert werden können, die auch umfassend in der Praxis zum Einsatz kommen. Es können zehn Erfolgsfaktoren zur Stärkung der Kundenorientierung identifiziert werden. Darüber hinaus kann aufgezeigt werden, dass Unternehmen, die die Erfolgsfaktoren berücksichtigen, sich besser an Veränderungen im Einkaufsverhalten der Kundschaft anpassen können und durchschnittlich 4 % mehr Gewinn erzielen. Somit wird die grundsätzliche Wirkungsweise der Kundenorientierung bestätigt. Die Erkenntnisse dieser Studie bieten für die Praxis eine fokussierte Vorgehensweise bei der Planung und Durchführung von Aktivitäten zur Stärkung der Kundenorientierung. Die Studie leistet einen Beitrag zur Erfolgsfaktorenforschung und dazu, Kundenorientierung als Managementmodell zu fundieren.

description: We study the energy transport between two interacting spin chains which are initially separated, held at different temperatures and subsequently put in contact. We consider the spin-1/2 XXZ model in the gapless regime and exploit its integrability properties to formulate an analytical Ansatz for the non-equilibrium steady state even at temperatures where the low-energy Luttinger liquid description is not accurate. We apply our method to compute the steady energy current and benchmark it both with the known low-energy limit and at higher temperatures with numerical simulations. We find an excellent agreement even at high temperatures, where the Luttinger liquid prediction is shown to fail.

The Most-Drunken Council

description: Judging by the frequency with which Peter I used religious language in his numerous letters, it could be argued that the tsar was a deeply religious man. However, his legislation points to the strength with which he tried to subordinate the official Orthodox church to himself, the culmination of which was the Spiritual Regulations that replaced the patriarchate with a collegial Synod subordinated to the tsarist government. However, the best image of Peter’s attitude to religion is the Most-Drunken Council, which he established at the beginning of his rule and which existed until the end of his life. The activities of this Council consisted of frequent revels and numerous ceremonies which were not devoid vulgarity mocking imitations of the rituals and doctrines of the Orthodox Church.

description: Dynamical properties of a long polymer ring in a melt of unknotted and unconcatenated rings are calculated. We re-examine and generalize the well known model of a ring confined to a lattice of topological obstacles in the light of the recently developed Flory theory of unentangled rings which maps every ring on an annealed branched polymer and establishes that the backbone associated with each ring follows self-avoiding rather than Gaussian random walk statistics. We find the scaling of ring relaxation time and diffusion coefficient with ring length, as well as time dependence of stress relaxation modulus, zero shear viscosity and mean square averaged displacements of both individual monomers and ring's mass center. Our results agree within error bars with all available experimental and simulations data of the ring melt, although the quality of the data so far is insufficient to make a definitive judgment for or against the annealed tree theory. In the end we review briefly the relation between our findings and experimental data on chromatin dynamics.

description: Soft elastic composite materials can serve as actuators when they transform changes in external fields into mechanical deformation. Here, we address the corresponding deformational behavior of magnetic gels and elastomers, consisting of magnetizable colloidal particles in a soft polymeric matrix and exposed to external magnetic fields. Since many practical realizations of such materials involve particulate inclusions of polydisperse size distributions, we concentrate on the effect that mixed particle sizes have on the overall deformational response. To perform a systematic study, our focus is on binary size distributions. We systematically vary the fraction of larger particles relative to smaller ones and characterize the resulting magnetostrictive behavior. The consequences for systems of various different spatial particle arrangements and different degrees of compressibility of the elastic matrix are evaluated. In parts, we observe a qualitative change in the overall response for selected systems of mixed particle sizes. Specifically, overall changes in volume and relative elongations or contractions in response to an induced magnetization can be reversed into the opposite types of behavior. Our results should apply to the characteristics of other soft elastic composite materials like electrorheological gels and elastomers when exposed to external electric fields as well. Overall, we hope to stimulate the further investigation on the purposeful use of mixed particle sizes as a means to design tailored requested material behavior.

description: Dieses Paper untersucht die Gründe, warum Nudging und weitere Erkenntnisse der Verhaltensökonomie im Marketing in der Schweiz deutlich weniger stark genutzt werden, als es aus der Perspektive der Wissenschaft naheliegend wäre. Es werden zunächst die Gründe hierfür analysiert sowie anschliessend herausgearbeitet, wie ein stärkerer Einsatz des Nudging-Konzeptes zu erreichen wäre. Die Erkenntnisse der Verhaltensökonomie sind im Marketing in der Schweiz nur mässig bekannt. Anwendung findet Nudging vor allem im Bereich der Wirtschafts- und beispielsweise Gesundheitspolitik. Im Marketing wird Nudging vor allem im Online-Handel im weiteren Sinne eingesetzt, nicht jedoch in der Breite des Marketings. Dies liegt vor allem daran, dass die Verhaltensökonomie kein greifbares geschlossenes Konzept darstellt, sondern eine Sammlung vieler einzelner Erkenntnisse. Die Forschung wird vor allem durch Ökonomen getrieben; eine Verbindung in die Marketingwissenschaft gibt es nur im Einzelfall. Gleichzeitig sind einzelne Erkenntnisse der Verhaltensökonomie unter anderem Namen im Marketing seit langer Zeit bekannt und werden nicht als relevant neu betrachtet. Das Wissen um nicht vollständig rationale Entscheidungen ist im Marketing etabliertes Wissen. Nudges werden auch ohne Kenntnis dieses Begriffes durchaus eingesetzt, zumeist aber nicht theoriegeleitet und bisweilen nicht evidenzbasiert, wie von den Verhaltensökonomen gefordert. Um die Erkenntnisse der Verhaltensökonomie und das Wissen über Nudging stärker in Marketing und Kommunikation zu verankern, erscheint es notwendig, weniger die Erkenntnisse und Methoden in den Mittelpunkt zu stellen, sondern sich stärker auf den Nutzen bei spezifischen Marketingaufgaben auszurichten. Hierfür entwickelt das Paper eine Heuristik, die die unübersichtliche Anzahl der Nudges in die Logik der Customer Journey einordnet.

description: Rund ein Drittel aller Berufslehrabschlüsse in der Schweiz entfallen auf die Berufslehre Kauffrau/Kaufmann. Studien belegen die Wichtigkeit des Ausbildungserfolgs für die unmittelbare berufliche Anschlusslösung und kumulativ für die weitere berufliche Laufb ahn. Die vorliegende Arbeit geht der Frage nach, welche Faktoren den Ausbildungserfolg in der dualen kaufmännischen Berufslehre, gemessen an der Abschlussnote, erklären. Mit den Daten von 320 Deutschschweizer kaufmännischen Berufslernenden werden, unter Berücksichtigung der Mehrebenenstruktur, Berechnungsmodelle entwickelt, welche eine Vielzahl von Faktoren auf der Mikro- und Mesoebene der Berufsausbildung auf ihre Vorhersagekraft des Ausbildungserfolgs prüfen. Die Ergebnisse zeigen, dass vor allem individuelle Faktoren der Lernenden, wie zum Beispiel Persönlichkeitsdimensionen, die Abschlussnoten erklären. Teils werden auch unterschiedliche Prädiktoren für die berufsfachschulische und die ausbildungsbetriebliche Berufslehrabschlussnote gefunden. So ist der Schulabschluss auf der Sekundarschule I für die berufsfachschulische, nicht aber für die ausbildungsbetriebliche Abschlussnote prädiktiv. Zudem werden unter gegenseitiger Kontrolle neben Faktoren der Person auch Faktoren der Berufsfachschule (Klassenzugehörigkeit) und des Ausbildungsbetriebs (z.B. Anzahl kaufmännische Lernende im Ausbildungsbetrieb) als prädiktiv für die Abschlussnoten festgestellt.

Roche-lobe overflow systems powered by black holes in young star clusters: the importance of dynamical exchanges

description: We have run 600 N-body simulations of intermediate-mass (~3500 Msun) young star clusters (SCs) with three different metallicities (Z=0.01, 0.1 and 1 Zsun). The simulations include the dependence of stellar properties and stellar winds on metallicity. Massive stellar black holes (MSBHs) with mass >25 Msun are allowed to form through direct collapse of very massive metal-poor stars (Z<0.3 Zsun). We focus on the demographics of black hole (BH) binaries that undergo mass transfer via Roche lobe overflow (RLO). We find that 44 per cent of all binaries that undergo an RLO phase (RLO binaries) formed through dynamical exchange. RLO binaries that formed via exchange (RLO-EBs) are powered by more massive BHs than RLO primordial binaries (RLO-PBs). Furthermore, the RLO-EBs tend to start the RLO phase later than the RLO-PBs. In metal-poor SCs (0.01-0.1 Zsun), >20 per cent of all RLO binaries are powered by MSBHs. The vast majority of RLO binaries powered by MSBHs are RLO-EBs. We have produced optical color-magnitude diagrams of the simulated RLO binaries, accounting for the emission of both the donor star and the irradiated accretion disk. We find that RLO-PBs are generally associated with bluer counterparts than RLO-EBs. We compare the simulated counterparts with the observed counterparts of nine ultraluminous X-ray sources. We discuss the possibility that IC 342 X-1, Ho IX X-1, NGC 1313 X-2 and NGC 5204 X-1 are powered by a MSBH.

description: We performed extreme ultraviolet spectroscopy using an 80 lines/mm TEM mesh as dispersive element. We present the usefulness of this instrument for dispersing a high harmonic spectrum from the 13th to the 29th harmonic of a Ti:Sapph laser, corresponding to a wavelength range from 60 to 27 nm. The resolution of the instrument is limited by the image size of the high harmonic generation region on the detector. The best resolution in first order diffraction is under 2 nm over the entire spectral range.

The propagation vector of the magnetic structure is found to be $\bf{k_{IC}}$=(1/2, 1/2, $k_l$) with $k_l$ increasing from $k_l$=0.298 to $k_l$=0.410 when $x$ increases from $x$=0 to $x$=0.26. Surprisingly, for $x$=0.30, the order has changed drastically and a commensurate antiferromagnetism with $\bf{k_{C}}$=(1/2, 1/2, 0) is found. This concentration is located in the proximity of the quantum critical point where superconductivity is expected.

description: This work introduces the Multimodal Diffusion Transformer (MDT), a novel diffusion policy framework, that excels at learning versatile behavior from multimodal goal specifi- cations with few language annotations. MDT leverages a diffusion based multimodal transformer backbone and two self-supervised auxiliary objectives to master long-horizon manipulation tasks based on multimodal goals. The vast majority of imitation learning methods only learn from individual goal modalities, e.g. either language or goal images. However, existing large- scale imitation learning datasets are only partially labeled with language annotations, which prohibits current methods from learning language conditioned behavior from these datasets. MDT addresses this challenge by introducing a latent goal- conditioned state representation, that is simultaneously trained on multimodal goal instructions. This state representation aligns image and language based goal embeddings and encodes suffi- cient information to predict future states. The representation is trained via two self-supervised auxiliary objectives that enhance the performance of the presented transformer backbone. MDT shows exceptional performance on 164 tasks provided by the chal- lenging CALVIN and LIBERO benchmarks, including a LIBERO version that contains less than 2% language annotations. Further, MDT establishes a new record on the CALVIN manipulation challenge, demonstrating an absolute performance improvement of 15% over prior state-of-the-art methods, that require large- scale pretraining and contain 10× more learnable parameters. MDT demonstrated its ability to solve long-horizon manipulation from sparsely annotated data in both simulated and real-world environments.
Open Scholarly Infrastructures for open access academic books: Enabling discoverability and seamless access to academic books from around the world

Open Infrastructure Services

description: Scholarly Communications is amidst a transition to Open Science – resulting in the more widespread availability of open content, data and research practices. Open Science also creates new opportunities for connecting regions, stakeholders and communities around infrastructure services. Two examples of 'open infrastructure services' are the Directory of Open Access Books (DOAB) and the OAPEN Library – two platforms dedicated to high quality, peer-reviewed, open access books. The Directory of Open Access Books (DOAB) indexes over 58,000 open access books, whereas the OAPEN Library provides a structured and premium hosting environment for over 24,000 OA books. The platforms are home to academic books from over 550 publishers and the platforms are used by thousands of libraries worldwide. Why are these open science infrastructures needed, why should they be open, and what global and local benefits do they offer? In this session we will briefly introduce these open infrastructures for open access books and their role in the wider transition to Open Science. Finally, we will look at the value these services offer to the wider scholarly community and engage around the question how this may benefit the MENA region.

The Morava K-theory of BO(q) and MO(q)

description: We give an easy proof that the Morava K-theories for BO(q) and MO(q) are in even degrees. Although this is a known result, it had followed from a difficult proof that BP^*(BO(q)) was Landweber flat. Landweber flatness follows from the even Morava K-theory. We go further and compute an explicit description of K(n)_*(BO(q)) and K(n)_*(MO(q)) and reconcile it with the purely algebraic construct from Landweber flatness.

Onset of Electron Acceleration in a Flare Loop

description: We carried out detailed analysis of X-ray and radio observations of a simple flare loop that occurred on 12th August 2002, with the impulsive hard X-ray (HXR) light curves dominated by a single pulse. The emission spectra of the early impulsive phase are consistent with an isothermal model in the coronal loop with a temperature reaching several keVs. A power-law high-energy spectral tail is evident near the HXR peak time, in accordance with the appearance of footpoints at high energies, and is well correlated with the radio emission. The energy content of the thermal component keeps increasing gradually after the disappearance of this nonthermal component. These results suggest that electron acceleration only covers a central period of a longer and more gradual energy dissipation process and that the electron transport within the loop plays a crucial role in the formation of the inferred power-law electron distribution. The spectral index of power-law photons shows a very gradual evolution indicating a quasi-steady state of the electron accelerator, which is confirmed by radio observations. These results are consistent with the theory of stochastic electron acceleration from a thermal background. Advanced modeling with coupled electron acceleration and spatial transport processes is needed to explain these observations more quantitatively, which may reveal the dependence of the electron acceleration on the spatial structure of the acceleration region.
