Article Synopsis
- - Surface morphology plays a crucial role in the effectiveness of electrocatalysts, and manipulating atomic-level structures can enhance their performance.
- - The study focused on how heat treatment in a specific reductive atmosphere at 300 °C influences the arrangement of surface atoms in platinum thin-film catalysts, improving their catalytic properties.
- - Results showed that increasing the proportion of (100) planes through thermal annealing can boost catalyst performance for methanol oxidation reactions significantly, highlighting a method for designing better electrocatalysts.
Background: Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) can assess tumour vascularity, which depends on the process of angiogenesis and affects tumour response to treatment. Our study explored the associations between DCE-MRI parameters and the expression of plasma angiogenic factors in human papilloma virus (HPV)-negative oropharyngeal cancer, as well as their predictive value for response to concurrent chemoradiotherapy (cCRT).
Patients And Methods: Twenty-five patients with locally advanced HPV-negative oropharyngeal carcinoma were prospectively enrolled in the study.
Chemical sensors, relying on changes in the electrical conductance of a gas-sensitive material due to the surrounding gas, typically react with multiple target gases and the resulting response is not specific for a certain analyte species. The purpose of this study was the development of a multi-sensor platform for systematic screening of gas-sensitive nanomaterials. We have developed a specific Si-based platform chip, which integrates a total of 16 sensor structures.

- Hematoma volume significantly impacts functional outcomes in acute intracerebral hemorrhage (ICH), with the study focusing on its relationship with neurological deficits at admission.
- A retrospective analysis of 338 patients revealed that NIHSS scores at admission mediated a portion of the variance in outcomes related to different ICH volumes, explaining 30% for smaller volumes and 14% for larger ones.
- Key findings suggest that larger ICH volumes and specific locations in the brain are linked to worsening neurological conditions, while factors like younger age and lower ICH volumes promote recovery, highlighting the need for considering additional factors beyond NIHSS for patient prognosis.
Despite theoretical benefits of collaborative robots, disappointing outcomes are well documented by clinical studies, spanning rehabilitation, prostheses, and surgery. Cognitive load theory provides a possible explanation for why humans in the real world are not realizing the benefits of collaborative robots: high cognitive loads may be impeding human performance. Measuring cognitive availability using an electrocardiogram, we ask 25 participants to complete a virtual-reality task alongside an invisible agent that determines optimal performance by iteratively updating the Bellman equation.
