Experimental Analysis on the Effect of Contact Pressure, Activity Level, and Skin Tone as Influencing Factors in PPG Sensors Performance

At present photoplethysmographic (PPG) sensors are rapidly spreading thanks to their multiple advantages: they are small, economic, and they can provide information on multidomain quantities related to cardiovascular health. For these reasons, research in this field is very active. Nonetheless, the measurement accuracy of this type of sensor and the factors that can interfere with their metrological performance are often neglected. The contact pressure between sensor and skin, the level of the activity performed by the subject, and also her/his skin tone are some of the quantities needing attention. The aim of this paper is to compare the measurement accuracy of a PPG sensor in relation to both contact pressure (20,60, and 75 mmHg) and walking/running speed (3,6, and 8 km/h) - using a cardiac belt as gold standard. Moreover, preliminary tests on dark skin subjects are performed to evaluate also the impact of this factor. The results show that the best performance is given at 60 mmHg and the uncertainty increases with activity level (passing from 8.2 bpm to 28.2 bpm when speed passes from 3 to 8 km/h, coverage factor k=2). Furthermore, it can be noticed that darker skin tone deteriorates the signal quality, increasing the mean absolute percentage error to values above 10% for speeds above 3 km/h. Plus, by considering the subjective optimal contact pressure at each speed, it is possible to improve significantly the accuracy and to reduce the mean absolute percentage error for moderate speed (6 km/h) at 1.89 %, which is known to be acceptable also for a clinical use. These results can be useful for researchers and producers of PPG-based wearable sensors, catching up on innovations potentially improving the quality of the measurement results. This could open new possibilities in terms of applications and stakeholders. In future, different wavelengths could be explored to expand the technology applicability

Brain network modulation in response to directional and Non-Directional Cues: Insights from EEG connectivity and graph theory

Objective: Directional cues have a profound impact on cognitive processes and behavior, and studying the involved brain networks can provide insights into their processing. This research aimed to investigate the neural network modulation associated with cognitive processing after the administration of directional cues using connectivity and graph theory. Methods: Twenty healthy volunteers were enrolled and underwent EEG recording while they were asked to perform a visuomotor task, such as directional (DS) and non-directional (nDS). From EEG data, network parameters such as Small-World (SW) and Lagged linear connectivity across different EEG frequency bands were evaluated, analyzing the response to DS and nDS. Results: The results revealed significant differences in the SW index, particularly in the Alpha 1 band, where participants exhibited a higher SW index when presented with DS compared to nDS. Moreover, the analysis of Alpha 1 band Lagged linear connectivity revealed close to statistically significant differences predominantly in the frontal and central regions. Conclusions: This research contributes to our understanding of the neural mechanisms underlying the processing of directional cues. Significance: It has potential implications for rehabilitation settings, for example in the rehabilitation of visual dysfunction and motor impairment following a stroke, by optimizing cognitive processing to enhance functional outcomes

Alternative colometriche negli Scholia vetera ad Aristofane

Some of the Scholia metrica vetera on the text of Aristophanes report the existence of several possible colometric divisions of the same portion of text. This paper focuses on selected Scholia to Peace and Clouds and investigates whether the attested colometric alternatives should be considered as deriving from different editions of the same comic text or only one colometry is authentic, with the others resulting from mistakes in the manuscripts tradition or being proposed by Heliodorus in his own commentary

Economy-Wide Material Flow Accounting: Application in the Italian Glass Industry

Italy supplies about one-seventh of the European Union’s total glass production, and the sector’s sizeable resource demands make it a linchpin of national industrial strategy. With growing environmental regulations and the push for resource efficiency, Material Flow Accounting has become essential for companies to stay compliant and advance sustainability. The investigation concentrates on Italy’s glass industry to clarify its material requirements, ecological footprint, and overall sustainability performance. STAN software v2, combined with an Economy-Wide Material Flow Accounting (EW-MFA) framework, models the national economy as a single integrated input–output system. By tracking each material stream from initial extraction to end-of-life, the analysis delivers a cradle-to-grave picture of the sector’s environmental impacts. During the 2021 production year, Italy’s glass makers drew on a total of 10.5 million tonnes (Mt) of material inputs, supplied 76% (7.9 Mt) from domestic quarries, and 24% (2.6 Mt) via imports. Outbound trade in finished glass removed 1.0 Mt, leaving 9.5 Mt recorded as Domestic Material Consumption (DMC). Within that balance, 6.6 Mt (63%) was locked into long-lived stock, whereas 2.9 Mt (28%) left the system as waste streams and airborne releases, including roughly 2.1 Mt of CO2. At present, the post-consumer cult substitutes only one-third of the furnace batch, signalling considerable scope for improved circularity. When benchmarked against EU-27 aggregates for 2021, Italy registers a NAS/DMI ratio of 0.63 (EU median 0.55) and a DPO/DMI ratio of 0.28 (EU 0.31), indicating a higher share of material retained in stock and slightly lower waste generated per ton of input. A detailed analysis of glass production identifies critical stages, environmental challenges, and areas for improvement. Quantitative data on material use, waste generation, and recycling rates reveal the industry’s environmental footprint. The findings emphasise Economy-Wide Material Flow Accounting’s value in evaluating and improving sustainability efforts, offering insights for policymakers and industry leaders to drive resource efficiency and sustainable resource management. Results help scholars and policymakers in the analysis of the Italian glass industry context, supporting in the data gathering, while also in the use of this methodology for other sectors

Inertial Sensing for Human Motion Analysis: Enabling Sensor-to-Body Calibration Through an Anatomical and Functional Combined Approach

The use of inertial measurement units is gaining attention to estimate human joint kinematics. However, to obtain clinically meaningful results, sensor frame needs to be aligned with the underlying anatomical one. Although during the years different approaches have been proposed, a common consensus has not been reached. Further, inertial sensor positioning on human segments can affect frame definition and kinematics estimation. Thus, the aim of the present work is to define an anatomical calibration procedure for lower limb joints kinematics, robust with respect to sensor misalignment, and based on a limited set of movements, with static and functional assumptions. To this purpose, straight walking and turning motor tasks in six healthy subjects were considered, and results were compared with those provided by an optoelectronic system. Three sensor placements have been also evaluated to test the procedure with respect to sensor positioning. After offset removal, an average RMSE ≤2.5 deg in gait, and ≤2 deg in turning for all the configurations were obtained, outperforming results from previous approaches. Average offset values resulted about 6 deg for hip and ankle, whereas negligible for the knee. Outcomes of this study enable a simple and accurate measurement of clinically meaningful joints kinematics, also without a strict sensor placement
