EMG-based wake gestures eliminate false activations during out-of-set activities of daily living: An online myoelectric control study.

Objective: While myoelectric control has been commercialized in prosthetics for decades, its adoption for more general human-machine interaction has been slow. Although high accuracies can be achieved across many gestures, current control approaches are prone to false activations in real-world conditions. This is because the same electromyogram (EMG) signals generated during the elicitation of gestures are also naturally activated when performing activities of daily living (ADLs), such as when driving to work or while typing on a keyboard.

Enhanced Advance care planning and life Review Longitudinal Intervention (EARLI): Protocol for a cluster randomized controlled cross-over trial of life story work and facilitated advance care planning among older Australian adults in community settings.

Background: Advance care planning (ACP) is potentially helpful for older adults, however, the rate of uptake in community aged care settings is low. Previous pilot studies suggest that holistic, person-centered ACP approaches may be effective for older adults who experience functional impairment but do not necessarily have life-limiting conditions with clear prognoses. This paper describes the protocol of a randomized trial to test the effectiveness of combined life story work and facilitated ACP in promoting ACP engagement among older adults receiving community aged care services.

Ion Spectroscopy in the Context of the Diffuse Interstellar Bands: A Case Study with the Phenylacetylene Cation.

Identification of the molecular carriers of diffuse interstellar bands (DIBs) requires gas phase electronic spectra of suitable candidate structures. Recording the spectra of these in the laboratory is challenging because they include large, carbon-rich molecules, many of which are likely to be ionic. The electronic spectra of ions are often obtained using action spectroscopy methods, which can induce small perturbations to the absorption characteristics and hinder comparison with astronomical observations.

Recent Advances in Selective Chemical Etching of Nanomaterials for High-Performance Electrodes in Electrocatalysis and Energy Storage.

To move beyond an energy economy dominated by fossil fuel utilization, high-performance electrochemical cells must be designed for energy storage and conversion. Selective etching is a promising, cost-effective solution-processing method for the large-scale top-down production of nanomaterials for high-performance electrodes. This review outlines general methodologies and mechanisms by which selective etching can be applied to create nanomaterials, including various template-assisted, facet-selective, and electrochemical methods, as well as in-depth case studies of state-of-the-art research involving selectively etched nanomaterials for electrocatalytic and energy storage applications.

A whole food, plant-based diet reduces amino acid levels in patients with metastatic breast cancer.

Background: Amino acids are critical to tumor survival. Tumors can acquire amino acids from the surrounding microenvironment, including the serum. Limiting dietary amino acids is suggested to influence their serum levels.
