Implantable electrochemical sensors for continuous blood monitoring

FlexMat, EarlyView.
Implantable electrochemical sensors enable direct, in situ, and continuous blood monitoring, shifting diagnosis from population‐based averages to dynamic, individualized analysis. This review systematically examines the influence of the unique blood properties on sensor design.

A unified framework for co-optimization of PFR and FFR reserves using linearized tri-criteria frequency constraints

International Journal of Electrical Power & Energy Systems
The increasing penetration of inverter-based resources reduces system inertia and heightens concerns about frequency stability. This paper proposes a systematic methodology for jointly optimizing primary frequency response (PFR) and fast frequency ...

The Impact of Uncertainty on Forecasting the US Economy

Journal of Forecasting, EarlyView.
ABSTRACT This paper examines the predictive value of uncertainty measures for key macroeconomic indicators across multiple forecast horizons. We evaluate how different uncertainty proxies—economic policy uncertainty (EPU), VIX, geopolitical risk, and measures of macroeconomic and financial uncertainty—enhance forecast accuracy for industrial production,

Toward SDG 13: A Machine Learning‐Based Assessment of Financial Freedom, Investment Freedom, and Environmental Sustainability

Sustainable Development, EarlyView.
ABSTRACT Previous studies in the context of the finance‐environment nexus mainly rely on quantitative indicators to provide information on activity or depth of the financial system, ignoring how institutional openness and the degree of regulatory autonomy within the financial market shape environmental outcomes that are directly relevant to Sustainable

The roles of multinational enterprises in governing the sustainability of global supply chains

International Journal of Management Reviews, EarlyView.
Abstract An extensive but fragmented body of research shows that multinational enterprises (MNEs) engage with multiple sustainability rules in global supply chains (GSCs) spanning the private, social and public governance sectors. MNEs perform diverse roles by either shaping or complying with these rules.

A Novel Approach for the Implementation of Fast Frequency Control in Low-Inertia Power Systems Based on Local Measurements and Provision Costs [PDF]

, 2022
Transitioning towards carbon-free energy has brought severe difficulties related to reduced inertia in electric power systems. Regarding frequency stability, low-inertia systems are more sensitive to disturbance, and traditional frequency control is ...

Musical Emotion Perception in Bimodal Patients: Relative Weighting of Musical Mode and Tempo Cues

Frontiers in Neuroscience, 2020
Several cues are used to convey musical emotion, the two primary being musical mode and musical tempo. Specifically, major and minor modes tend to be associated with positive and negative valence, respectively, and songs at fast tempi have been ...
