Asymmetric Dual-Arm Task Execution Using an Extended Relative Jacobian

Coordinated dual-arm manipulation tasks can be broadly characterized as possessing absolute and relative motion components. Relative motion tasks, in particular, are inherently redundant in the way they can be distributed between end-effectors. In this work, we analyse cooperative manipulation in terms of the asymmetric resolution of relative motion tasks. We discuss how existing approaches enable

Extracting structural motifs from pair distribution function data of nanostructures using explainable machine learning

Characterization of material structure with X-ray or neutron scattering using e.g. Pair Distribution Function (PDF) analysis most often rely on refining a structure model against an experimental dataset. However, identifying a suitable model is often a bottleneck. Recently, automated approaches have made it possible to test thousands of models for each dataset, but these methods are computationall

Your vibe attracts your tribe – the adaptive reuse of buildings delivering aesthetic experience and social inclusion

A significant amount of embodied energy, materials, and economic capital is tied to vacant and underused buildings. Sharing is an effective way to reduce the excess use of space. Beside sharing, much more focus should be placed on maximizing the functional use of existing buildings. Adaptive reuse can be effective not only in mitigating obsolescence, but also in enhancing the vitality of site surr

Televised stations in Italy : The visualisation of mobility on transportation hubs video networks

Passenger journeys increasingly include mediality in its various manifestations. Mass-transit systems need clear signs, often featured in the form of audiovisual media, and transmitted through displays working for captive and in-transit audiences. With reference to Italian biggest railway stations, the chapter explores the reconfiguration of those television-like networks (commonly known as ‘go-tv

Staff Radiation Protection

From a radiation protection point of view, nuclear medicine is a complex medical specialty that includes both radionuclide and radiopharmaceutical production and patient diagnostics and therapy. The practical work with radiation sources includes a variety of procedures, activity levels, dose rates, and risks of contamination. The radiation dose to the worker is largely determined by the knowledge

Reversible Atomization and Nano-Clustering of Pt as a Strategy for Designing Ultra-Low-Metal-Loading Catalysts

Noble metal-based catalysts have numerous industrial uses, and maximum utilization of the precious metals by lowering the metal loading is of significant interest in heterogeneous catalysis research. However, lowering the metal loading could lead to single-atom metal species formation, which may not be active for important reactions like propylene oxidation. We report a way to drastically reduce p

ANGPTL7, a therapeutic target for increased intraocular pressure and glaucoma

Glaucoma is a leading cause of blindness. Current glaucoma medications work by lowering intraocular pressure (IOP), a risk factor for glaucoma, but most treatments do not directly target the pathological changes leading to increased IOP, which can manifest as medication resistance as disease progresses. To identify physiological modulators of IOP, we performed genome- and exome-wide association an

Are Gender-Neutral Pronouns Really Neutral? Testing a Male Bias in the Grammatical Genderless Languages Turkish and Finnish

Languages differ in how grammatically salient gender is. We explored if grammatically gender-neutral pronouns in Finnish and Turkish, two grammatically genderless languages, are gender neutral or male biased, thereby activating male, rather than female, exemplars. We also tested whether differences in national level gender equality influence the male bias. Results indicated a male bias in both lan

N-doping of nonfullerene bulk-heterojunction organic solar cells strengthens photogeneration and exciton dissociation

N-type doping of the bulk-heterojunction layer in nonfullerene organic solar cells allows to effectively ameliorate inferior electron transportation by filling traps and optimizing electron pathways, leading to a better balance of charge transport in device. This mechanism, however, provides an incomplete understanding of the stronger photogeneration, long-lived excitons and simultaneously increas

Prey capture by the non-native carnivorous pitcher plant Sarracenia purpurea across sites in Britain and Ireland

The carnivorous pitcher plant Sarracenia purpurea is native to North America, but has been introduced into Europe, where it is now widespread. Understanding of how this species functions in its non-native range is limited. We measured pitcher morphology and prey capture by S. purpurea in its non-native range in Britain and Ireland. Pitchers were removed from different plants at each of six bogs co

Some Results on Oscillation Stability in Multi-Mode Harmonic Oscillators

We study the stability of oscillation in two different multi-mode harmonic oscillators by means of Barkhausen’s criterion, involving a minimum of mathematical machinery in favor of a more intuitive, circuit-based approach. The results of the theoretical analysis match very closely those obtained through transient simulations, confirming occasionally surprising outcomes of the latter.

Membrane Assemblies with Soft Protective Layers : Dense and Gel-Type Polybenzimidazole Membranes and Their Use in Vanadium Redox Flow Batteries

Polybenzimidazole (PBI) membranes show excellent chemical stability and low vanadium crossover in vanadium redox flow batteries (VRFBs), but their high resistance is challenging. This work introduces a concept, membrane assemblies of a highly selective 2 µm thin PBI membrane between two 60 µm thick highly conductive PBI gel membranes, which act as soft protective layers against external mechanical

m2ABQ—a proposed refinement of the modified algorithm-based qualitative classification of osteoporotic vertebral fractures

Summary: Currently, there is no reproducible, widely accepted gold standard to classify osteoporotic vertebral body fractures (OVFs). The purpose of this study is to refine a method with clear rules to classify OVFs for machine learning purposes. The method was found to have moderate interobserver agreement that improved with training. Introduction: The current methods to classify osteoporotic ver

Online Representations of Older People Generated by Public Sector Organizations

This article investigates the generation of online representations of older people by institutions. Specifically, it discusses the ways in which public sector organizations generate online representations of older people from a production perspective. This article uses the following questions to frame its analysis: What do we know about online representations of older people generated by public se
