Pedestrian Prediction by Planning using Deep Neural Networks

Accurate traffic participant prediction is the prerequisite for collision avoidance of autonomous vehicles. In this work, we predict pedestrians by emulating their own motion planning. From online observations, we infer a mixture density function for possible destinations. We use this result as the goal states of a planning stage that performs motion prediction based on common behavior patterns. The entire system is modeled as one monolithic neural network and trained via inverse reinforcement learning. Experimental validation on real world data shows the system's ability to predict both, destinations and trajectories accurately

An inventory of yeast proteins associated with nucleolar and ribosomal components

BACKGROUND: Although baker's yeast is a primary model organism for research on eukaryotic ribosome assembly and nucleoli, the list of its proteins that are functionally associated with nucleoli or ribosomes is still incomplete. We trained a naïve Bayesian classifier to predict novel proteins that are associated with yeast nucleoli or ribosomes based on parts lists of nucleoli in model organisms and large-scale protein interaction data sets. Phylogenetic profiling and gene expression analysis were carried out to shed light on evolutionary and regulatory aspects of nucleoli and ribosome assembly. RESULTS: We predict that, in addition to 439 known proteins, a further 62 yeast proteins are associated with components of the nucleolus or the ribosome. The complete set comprises a large core of archaeal-type proteins, several bacterial-type proteins, but mostly eukaryote-specific inventions. Expression of nucleolar and ribosomal genes tends to be strongly co-regulated compared to other yeast genes. CONCLUSION: The number of proteins associated with nucleolar or ribosomal components in yeast is at least 14% higher than known before. The nucleolus probably evolved from an archaeal-type ribosome maturation machinery by recruitment of several bacterial-type and mostly eukaryote-specific factors. Not only expression of ribosomal protein genes, but also expression of genes encoding the 90S processosome, are strongly co-regulated and both regulatory programs are distinct from each other

Computability in basic quantum mechanics

The basic notions of quantum mechanics are formulated in terms of separable infinite dimensional Hilbert space H. In terms of the Hilbert lattice L of closed linear subspaces of H the notions of state and observable can be formulated as kinds of measures as in [21]. The aim of this paper is to show that there is a good notion of computability for these data structures in the sense of Weihrauch’s Type Two Effectivity (TTE) [26]. Instead of explicitly exhibiting admissible representations for the data types under consideration we show that they do live within the category QCB0 which is equivalent to the category AdmRep of admissible representations and continuously realizable maps between them. For this purpose in case of observables we have to replace measures by valuations which allows us to prove an effective version of von Neumann’s Spectral Theorem

Die Sozialfigur des Ehrenamtlichen im Roten Kreuz - Ergebnisse einer vergleichenden empirischen Untersuchung

Auf der Grundlage eines neu erhobenen Datensatzes werden die sozioökonomischen Charakteristika der Ehrenamtlichen im Deutschen Roten Kreuz beschrieben. Zudem wird auf der Basis theoretischer Überlegungen ein Vergleich mit den Ehrenamtlichen in Fußballvereinen gezogen. Damit wird ein Vergleich des Ehrenamts in altruistischen bzw. egoistischen Organisationstypen möglich. Theoriegeleitet werden Hypothesen zur Schichtabhängigkeit, zu den Motiven der Ehrenamtlichen und dem Umfang ihres Engagements und ihren Nutzenerfahrungen geprüft. Abschließend werden auf der Grundlage der empirischen Befunde Empfehlungen zur Rekrutierung und Bindung Ehrenamtlicher erarbeitet.Using a new dataset, we study the socioeconomic characteristics of volunteers working for the German Red Cross. Based on theoretical considerations, we compare volunteers of the German Red Cross with volunteers working for German football clubs. Such a comparison allows volunteerism in altruistic versus egoistic clubs to be studied. We use our theoretical considerations to derive hypotheses regarding the class-dependence of volunteerism, the motives of volunteers and the time they spent on volunteering, and the utility volunteers derive from their work. Against the background of our empirical results, we discuss how the recruitment of volunteers and their commitment can be strengthened

Ionothermal Synthesis, Crystal Structure, and Magnetic Study of Co2PO4OH Isostructural with Caminite

A new framework cobalt(II) hydroxyl phosphate, Co2PO4OH, was prepared by ionothermal synthesis using 1-butyl-4-methyl-pyridinium hexafluorophosphate as the ionic liquid. As the formation of Co2PO4F competes in the synthesis, the synthesis conditions have to be judiciously chosen to obtain well-crystallized, single phase Co2PO4OH. Single-crystal X-ray diffraction analyses reveal Co2PO4OH crystallizes with space group I41/amd (a = b = 5.2713(7) Å, c = 12.907(3) Å, V = 358.63(10) Å3, and Z = 4). Astonishingly, it does not crystallize isotypically with Co2PO4F but rather isotypically with the hydroxyl minerals caminite Mg1.33[SO4(OH)0.66(H2O)0.33] and lipscombite Fe2–yPO4(OH) (0 ≤ y ≤ 2/3). Phosphate tetrahedra groups interconnect four rod-packed face-sharing ∞1{CoO6/2} octahedra chains to form a three-dimensional framework structure. The compound Co2PO4OH was further characterized by powder X-ray diffraction, Fourier transform–infrared, and ultraviolet–visible spectroscopy, confirming the discussed structure. The magnetic measurement reveals that Co2PO4OH undergoes a magnetic transition and presents at low temperatures a canted antiferromagnetic spin order in the ground state
