Improving the performance of cable-driven parallel robots through control, modeling, and calibration See

Cable-driven parallel robots (CDPRs) are a class of robots offering a unique combination of properties: a large workspace, high dynamics, and high payloads. This enables them to be used in various applications where other types of robots are unsuitable. Unfortunately, the potential of&#...

Protein kinase D promotes activity‐dependent AMPA receptor endocytosis in hippocampal neurons See

α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazolepropionic acid (AMPA) type glutamate receptors (AMPARs) mediate the majority of fast excitatory neurotransmission in the brain. The continuous trafficking of AMPARs into and out of synapses is a core feature of synaptic plasticity, which is considered as the cellu...

Manufacture and thermomechanical characterization of wet filament wound C/C‐SiC composites See

The paper presents manufacture of C/C‐SiC composite materials by wet filament winding of C fibers with a water‐based phenolic resin with subsequent curing via autoclave as well as pyrolysis and liquid silicon infiltration (LSI). Almost dense C/C‐SiC composite materials with different&#x...

Effects of acute exercise at different intensities on fine motor‐cognitive dual‐task performance while walking : a functional near‐infrared spectroscopy study See

Studies on the effects of acute exercises on cognitive functions vary greatly and depend on the duration and intensity of exercise and the type of cognitive tasks. This study aimed to investigate the neural correlates that underpin the acute effects of high‐intensity interval (HIIE...

Visual analysis of large‐scale protein‐ligand interaction data See

When studying protein‐ligand interactions, many different factors can influence the behaviour of the protein as well as the ligands. Molecular visualisation tools typically concentrate on the movement of single ligand molecules; however, viewing only one molecule can merely provide a hint of...

Widersprüche als Potenziale : Konzept für einen Multidialektischen Städtebau am Beispiel großer Quartiersplanungen See

Die Dissertation untersucht ‚Widersprüche als Potenziale‘ zur Differenzierung von homogenen großen Quartiersplanungen. Philosophische Grundlage ist das dialektische Denken mit der Vermittlung zwischen Widersprüchen als Kernanliegen und der Differenziertheit des Ganzen als Ziel. Die Untersuchung großer Quartiersplanungen&...

Calibration of fiber orientation simulations for LFT : a new approach See

Short fiber reinforced thermoplastics (SFT) are extensively used due to their excellent mechanical properties and low processing costs. Long fiber reinforced thermoplastics (LFT) show an even more interesting property profile and are increasingly used for structural parts. However, their processing&#x...

Bayesian calibration and validation of a large‐scale and time‐demanding sediment transport model See

This study suggests a stochastic Bayesian approach for calibrating and validating morphodynamic sediment transport models and for quantifying parametric uncertainties in order to alleviate limitations of conventional (manual, deterministic) calibration procedures. The applicability of our method is shown f...

Stereospezifische asymmetrische Synthese tertiärer Allylalkohol‐ Derivate über katalytische [2,3]‐Meisenheimer‐Umlagerungen See

Chirale azyklische tertiäre Allylalkohole sind bedeutende Synthesebausteine, deren enantioselektive Synthese eine anspruchsvolle Aufgabe ist. Eine wesentliche Einschränkung bei katalytisch asymmetrischen 1,2-Additionen an Ketone ist die Enantioseitendifferenzierung durch sterische Unterscheidung beider Ketonreste. Um dieses Proble...

Maneuvering the bumps in the New Silk Road : open innovation, technological complexity, dominant design, and the international impact of Chinese innovation See

Chinese innovation is again flowing westwards, which is fomented by China’s Belt and Road Initiative. In this context, we study the international impact of innovations from specific countries. Based on panel data of patents from 27 countries over 17 years, we find that levels of&#x...

Strategies for simplifying reactive transport models : a Bayesian model comparison See

For simulating reactive transport on aquifer scale, various modeling approaches have been proposed. They vary considerably in their computational demands and in the amount of data needed for their calibration. Typically, the more complex a model is, the more data are required to su...

Cationic group VI metal imido alkylidene N‐heterocyclic carbene nitrile complexes : bench‐stable, functional‐group‐tolerant olefin metathesis catalysts See

Despite their excellent selectivities and activities, Mo‐and W‐based catalysts for olefin metathesis have not gained the same widespread use as Ru‐based systems, mainly due to their inherent air sensitivity. Herein, we describe the synthesis of air‐stable cationic‐at‐metal molybdenum and tungsten ...

Isomerization reactions in anionic mesoionic carbene-borates and control of properties and reactivities in the resulting CoII complexes through agostic interactions See

We present herein anionic borate‐based bi‐mesoionic carbene compounds of the 1,2,3‐triazol‐4‐ylidene type that undergo C-N isomerization reactions. The isomerized compounds are excellent ligands for CoII centers. Strong agostic interactions with the “C-H”‐groups of the cyclohexyl substituents result in an ...

Modifizierte Enzyme ermöglichen die selektive N‐Alkylierung von Pyrazolen unter Verwendung einfacher Halogenalkane See

Die selektive Alkylierung von Pyrazolen ist eine Herausforderung in der Chemie und könnte die Synthese wichtiger Moleküle vereinfachen. In dieser Arbeit berichten wir über eine katalysatorgesteuerte Alkylierung von Pyrazolen durch eine cyclische Kaskadenreaktion mit zwei Enzymen. In diesem enzymatischen&#x...

Two light‐metal dihydrogenisocyanurate hydrates linked by diagonal relationship : syntheses, crystal structures, and vibrational spectra of Li[H2N3C3O3]·1.75 H2O and Mg[H2N3C3O3]2·8 H2O See

Single‐crystalline materials of Li[H2N3C3O3]·1.75 H2O and Mg[H2N3C3O3]2·8 H2O were obtained by dissolving stoichiometric amounts of the respective carbonates with cyanuric acid in boiling water followed by gentle evaporation of excess water after cooling to room temperature. Even though both of t...

Extending quantum links : modules for fiber‐ and memory‐based quantum repeaters See

Elementary building blocks for quantum repeaters based on fiber channels and memory stations are analyzed. Implementations are considered for three different physical platforms, for which suitable components are available: quantum dots, trapped atoms and ions, and color centers in diamond. The&#x...

Exploring the full potential of photocatalytic carbon dioxide reduction using a dinuclear Re2Cl2 complex assisted by various photosensitizers See

Photosensitizing units have already been applied to enable light‐driven catalytic reduction of CO2 with mononuclear rhenium complexes. However, dinuclear catalytic systems that are able to activate CO2 in a cooperative bimetallic fashion have only rarely been combined with photosensitizers. We he...

Revisiting and generalizing the dual iteration for static and robust output‐feedback synthesis See

The dual iteration was introduced in a conference paper in 1997 by Iwasaki as an iterative and heuristic procedure for the challenging and non‐convex design of static output‐feedback controllers. We recall in detail its essential ingredients and go beyond the work of Iwasaki by...
