Published: February 2024

Walking rehabilitation following injury or disease involves voluntary gait modification, yet the specific brain signals underlying this process remains unclear. This aim of this study was to investigate the impact of an auditory cue on changes in brain activity when walking overground (O) and on a treadmill (T) using an electroencephalogram (EEG) with a 32-electrode montage. Employing a between-group repeated-measures design, 24 participants (age: 25.7 ± 3.8 years) were randomly allocated to either an O (n = 12) or T (n = 12) group to complete two walking conditions (self-selected speed control (sSC) and speed control (SC)). The differences in brain activities during the gait cycle were investigated using statistical non-parametric mapping (SnPM). The addition of an auditory cue did not modify cortical activity in any brain area during the gait cycle when walking overground (all p > 0.05). However, significant differences in EEG activity were observed in the delta frequency band (0.5–4 Hz) within the sSC condition between the O and T groups. These differences occurred at the central frontal (loading phase) and frontocentral (mid stance phase) brain areas (p < 0.05). Our data suggest auditory cueing has little impact on modifying cortical activity during overground walking. This may have practical implications in neuroprosthesis development for walking rehabilitation, sports performance optimization, and overall human quality-of-life improvement.

Authors: Zhang Yingzhe , Caccese Jaclyn B. , Kiourti Asimina
Published: February 2024

We have previously reported wearable loop sensors that can accurately monitor knee flexion with unique merits over the state of the art. However, validation to date has been limited to single-leg configurations, discrete flexion angles, and in vitro (phantom-based) experiments. In this work, we take a major step forward to explore the bilateral monitoring of knee flexion angles, in a continuous manner, in vivo. The manuscript provides the theoretical framework of bilateral sensor operation and reports a detailed error analysis that has not been previously reported for wearable loop sensors. This includes the flatness of calibration curves that limits resolution at small angles (such as during walking) as well as the presence of motional electromotive force (EMF) noise at high angular velocities (such as during running). A novel fabrication method for flexible and mechanically robust loops is also introduced. Electromagnetic simulations and phantom-based experimental studies optimize the setup and evaluate feasibility. Proof-of-concept in vivo validation is then conducted for a human subject performing three activities (walking, brisk walking, and running), each lasting 30 s and repeated three times. The results demonstrate a promising root mean square error (RMSE) of less than 3° in most cases.

Published: February 2024

Sensor degradation and failure often undermine users’ confidence in adopting a new data-driven decision-making model, especially in risk-sensitive scenarios. A risk assessment framework tailored to classification algorithms is introduced to evaluate the decision-making risks arising from sensor degradation and failures in such scenarios. The framework encompasses various steps, including on-site fault-free data collection, sensor failure data collection, fault data generation, simulated data-driven decision-making, risk identification, quantitative risk assessment, and risk prediction. Leveraging this risk assessment framework, users can evaluate the potential risks of decision errors under the current data collection status. Before model adoption, ranking risk sensitivity to sensor data provides a basis for optimizing data collection. During the use of decision algorithms, considering the expected lifespan of sensors enables the prediction of potential risks the system might face, offering comprehensive information for sensor maintenance. This method has been validated through a case study involving an access control.

Authors: Lee Jin-Shyan , Chen Ze-Hua , Hong Yue
Published: February 2024

In smart cities, bicycle-sharing systems have become an essential component of the transportation services available in major urban centers around the globe. Due to environmental sustainability, research on the power-assisted control of electric bikes has attracted much attention. Recently, fuzzy logic controllers (FLCs) have been successfully applied to such systems. However, most existing FLC approaches have a fixed fuzzy rule base and cannot adapt to environmental changes, such as different riders and roads. In this paper, a modified FLC, named self-tuning FLC (STFLC), is proposed for power-assisted bicycles. In addition to a typical FLC, the presented scheme adds a rule-tuning module to dynamically adjust the rule base during fuzzy inference processes. Simulation and experimental results indicate that the presented self-tuning module leads to comfortable and safe riding as compared with other approaches. The technique established in this paper is thought to have the potential for broader application in public bicycle-sharing systems utilized by a diverse range of riders.

Published: February 2024

We propose a new methodology for long-term biopotential recording based on an MEMS multisensor integrated platform featuring a commercial electrostatic charge-transfer sensor. This family of sensors was originally intended for presence tracking in the automotive industry, so the existing setup was engineered for the acquisition of electrocardiograms, electroencephalograms, electrooculograms, and electromyography, designing a dedicated front-end and writing proper firmware for the specific application. Systematic tests on controls and nocturnal acquisitions from patients in a domestic environment will be discussed in detail. The excellent results indicate that this technology can provide a low-power, unexplored solution to biopotential acquisition. The technological breakthrough is in that it enables adding this type of functionality to existing MEMS boards at near-zero additional power consumption. For these reasons, it opens up additional possibilities for wearable sensors and strengthens the role of MEMS technology in medical wearables for the long-term synchronous acquisition of a wide range of signals.

Published: February 2024

In modern society, the popularity of wearable devices has highlighted the need for data security. Bio-crypto keys (bio-keys), especially in the context of wearable devices, are gaining attention as a next-generation security method. Despite the theoretical advantages of bio-keys, implementing such systems poses practical challenges due to their need for flexibility and convenience. Electrocardiograms (ECGs) have emerged as a potential solution to these issues but face hurdles due to intra-individual variability. This study aims to evaluate the possibility of a stable, flexible, and convenient-to-use bio-key using ECGs. We propose an approach that minimizes biosignal variability using normalization, clustering-based binarization, and the fuzzy extractor, enabling the generation of personalized seeds and offering ease of use. The proposed method achieved a maximum entropy of 0.99 and an authentication accuracy of 95%. This study evaluated various parameter combinations for generating effective bio-keys for personal authentication and proposed the optimal combination. Our research holds potential for security technologies applicable to wearable devices and healthcare systems.
Performance of the Thies Clima 3D Stereo Disdrometer: Evaluation during Rain and Snow Events
Authors: Angeloni Sabina , Adirosi Elisa , Bracci Alessandro , Montopoli Mario , Baldini Luca
Published: February 2024

Imaging disdrometers are widely used in field campaigns to provide information on the shape of hydrometeors, together with the diameter and the fall velocity, which can be used to derive information on the shape–size relations of hydrometeors. However, due to their higher price compared to laser disdrometers, their use is limited to scientific research purposes. The 3D stereo (3DS) is a commercial imaging disdrometer recently made available by Thies Clima and on which there are currently no scientific studies in the literature. The most innovative feature of the 3DS is its ability in capturing images of the particles passing through the measurement volume, crucial to provide an accurate classification of hydrometeors based on information about their shape, especially in the case of solid precipitation. In this paper. the performance of the new device is analyzed by comparing 3DS with the Laser Precipitation Monitor (LPM) from the same manufacturer, which is a known laser disdrometer used in many research works. The data used in this paper were obtained from measurements of the two instruments carried out at the Casale Calore site in L’Aquila during the CORE-LAQ (Combined Observations of Radar Experiments in L’Aquila) campaign. The objective of the comparison analysis is to analyze the differences between the two disdrometers in terms of hydrometeor classification, number and falling speed of particles, precipitation intensity, and total cumulative precipitation on an event basis. As regards the classification of precipitation, the two instruments are in excellent agreement in identifying rain and snow; greater differences are observed in the case of particles in mixed phase (rain and snow) or frozen phase (hail). Due to the different measurement area of the two disdrometers, the 3DS generally detects more particles than the LPM. The performance differences also depend on the size of the hydrometeors and are more significant in the case of small particles, i.e., D < 1 mm. In the case of rain events, the two instruments are in agreement with respect to the terminal velocity in still air predicted by the Gunn and Kinzer model for drops with a diameter of less than 3 mm, while, for larger particles, terminal velocity is underestimated by both the disdrometers. The agreement between the two instruments in terms of total cumulative precipitation per event is very good. Regarding the 3DS ability to capture images of hydrometeors, the raw data provide, each minute, from one to four images of single particles and information on their size and type. Their number and coarse resolution make them suitable to support only qualitative analysis of the shape of precipitating particles.

Published: February 2024

In the validation of microclimate simulation software, the comparison of simulation results with on-site measurements is a common practice. To ensure reliable validation, it is crucial to utilize high-quality temperature sensors with a deviation smaller than the average absolute error of the simulation software. However, previous validation campaigns have identified significant absolute errors, particularly during periods of high solar radiation, possibly attributed to the use of non-ventilated radiation shields. This study addresses the issue by introducing a ventilated radiation shield created through 3D printing, aiming to enhance the accuracy of measurements on cloudless summer days with intense solar radiation. The investigation employs two pairs of sensors, each comprising one sensor with a ventilated and one with a non-ventilated radiation shield, placed on a south-oriented facade with two distinct albedos. Results from the measurement campaign indicate that the air temperature measured by the non-ventilated sensor is elevated by up to 2.8 °C at high albedo and up to 1.9 °C at a low albedo facade, compared to measurements with the ventilated radiation shield. An in-depth analysis of means, standard deviations, and 95% fractiles highlights the strong dependency of the non-ventilated sensor error on wind velocity. This research underscores the importance of employing ventilated radiation shields for accurate microclimate measurements, particularly in scenarios involving high solar radiation, contributing valuable insights for researchers and practitioners engaged in microclimate simulation validation processes.

Authors: Yang Chang-Ho , Chuang Mei-Chen , Chen Der-Fa
Published: February 2024

A circular economy is a concept of sustainable development that enhances a company’s image and influences consumers’ attitudes toward the corporation. Trust, commitment, and identification in relationship marketing are key factors for fostering long-term relationships. This study aimed to examine the relationship quality and attitudes between higher education students’ personal environmental perspectives and circular economy products, further investigating their impact on the purchase intention of circular economy products. Therefore, this research proposed and tested a theoretical framework that combined variables, including environmental concern, environmental awareness, relationship quality with circular economy products, and attitudes, to determine the influencing factors on higher education students’ purchase intention of circular economy products. This study adopted a survey design method and employed partial least squares structural equation modeling (PLS-SEM) to analyze data from 443 higher education students from Taiwan and Thailand. The results indicated that environmental awareness and environmental concern are critical antecedent factors for attitude and relationship quality (trust and identification) in circular economy products. In addition, trust and attitude in circular economy products have a significant impact on commitment. Furthermore, trust, commitment, and identification with circular economy products are crucial determining factors for the purchase intention of circular economy products. The findings contribute to a deeper understanding of the factors influencing higher education students’ purchase intention of circular economy products, thereby achieving the goal of environmental sustainability.
A Simple Quantum Picture of the Relativistic Doppler Effect
Authors: Hodgson Daniel , Kanzi Sara , Beige Almut
Published: February 2024

The relativistic Doppler effect comes from the fact that observers in different inertial reference frames experience space and time differently, while the speed of light always remains the same. Consequently, a wave packet of light exhibits different frequencies, wavelengths, and amplitudes. In this paper, we present a local approach to the relativistic Doppler effect based on relativity, spatial and time translational symmetries, and energy conservation. Afterwards, we investigate the implications of the relativistic Doppler effect for the quantum state transformations of wave packets of light and show that a local photon is a local photon at the same point in the spacetime diagram in all inertial frames.

Introduction: The prognostic value of CT-derived liver volume in terms of cancer outcomes is not clear. The aim of the present study was to examine the relationship between liver area on a single axial CT-slice and the total liver volume in patients with colonic cancer. Furthermore, we examine the relationship between liver volume, determined using this novel method, clinicopathological variables and survival. Methods: Consecutive patients who underwent potentially curative surgery for colonic cancer were identified from a prospectively maintained database. Maximal liver area on axial CT-slice (cm2) and total volume (cm3), were obtained by the manual segmentation of pre-operative CT-images in a PACS viewer. The maximal liver area was normalized for body height2 to create the liver index (LI) and values, categorized into tertiles. The primary outcome of interest was overall survival (OS). Relationships between LI and clinico-pathological variables were examined using chi-square analysis and binary logistic regression. The relationship between LI and OS was examined using cox proportional hazard regression. Results: A total of 359 patients were included. A total of 51% (n = 182) of patients were male and 73% (n = 261) were aged 65 years or older. 81% (n = 305) of patients were alive 3-years post-operatively. The median maximal liver area on the axial CT slice was 178.7 (163.7–198.4) cm2. The median total liver volume was 1509.13 (857.8–3337.1) cm3. Maximal liver area strongly correlated with total liver volume (R2 = 0.749). The median LI was 66.8 (62.0–71.6) cm2/m2. On multivariate analysis, age (p < 0.001), sex (p < 0.05), BMI (p < 0.001) and T2DM (p < 0.05) remained significantly associated with LI. On univariate analysis, neither LI (continuous) or LI (tertiles) were significantly associated with OS (p = 0.582 and p = 0.290, respectively). Conclusions: The simple, reliable method proposed in this study for quantifying liver volume using CT-imaging was found to have an excellent correlation between observers and provided results consistent with the contemporary literature. This method may facilitate the further examination of liver volume in future cancer studies.
Impact of Conditioning Agent Addition Sequence on Dewatering Performance of Advanced Anaerobic Digested Sludge
Authors: Cao Xiuqin , Yu Ran , Wang Xin
Published: February 2024

The advanced anaerobic digestion process enhances sludge resource utilization. However, thermal hydrolysis pretreatment of anaerobically digested sludge reduces dewatering efficiency due to excessive organic matter decomposition. This necessitates significant time and effort for sludge conditioning in wastewater treatment plants. Using conditioning agents can achieve high dewatering efficiency. This study investigates how the order of adding coagulants and flocculants impacts the dewatering performance of digested sludge. The results indicate that, compared to the flocculation–coagulation process with the same dosage, the coagulation–flocculation process leads to a 15–20% increase in the average particle size of digested sludge. The content of polysaccharides and proteins in S-EPS decreases by 28.8–30.8% and 10.1–11.3%, respectively. The filter cake solids content increases by 8.5%, and there is an increase in surface water channels within the flocs. This is because initially adding coagulants efficiently adsorbs small particles, forming larger aggregates that settle effectively. This promotes the breakdown of extracellular polymeric substances, releasing more bound water. Adding flocculants later bridges the aggregates, further enhancing settling and filtration performance, thereby improving sludge dewatering efficiency. These research findings contribute to a better understanding of the mechanisms of coagulant and flocculant co-conditioning for digested sludge and provide recommendations for optimizing sludge conditioning steps.
Borderless offices : Opportunity for tax optimisation?
Authors: Tóth Orsolya Éva
Published: February 2024

The prevalence of telework, or working remotely or from home, has grown significantly in recent years, in which the COVID-19 pandemic played a major role. This paper focuses on a narrower subsection of remote work arrangements, and analyses employees’ possibilities for tax optimization and potential taxation risks in the context of cross-border remote work or telework. Major obstacles to the spread of remote work are identified by investigating the challenges associated with cross-border remote work from an employer’s perspective. As a further objective, the paper aims to explore how jobs offered in the Hungarian labour market, but performed remotely from abroad influence domestic tax revenues. Three scenarios were developed which reveal that the budget of Hungary suffers at least HUF 46 billion loss in fiscal revenues if 10% of remote job vacancies are filled from across Hungary’s borders. If only 50% of remote/workfrom-home job vacancies are filled within borders, the potential loss in revenue from taxes and contributions is HUF 229 billion. The research conducted under this study highlights the tax consequences of technology-driven changes in the labour market for individuals, employers and central budgets. States need to consider these factors when shaping their tax systems to ensure sustainable tax revenues.

Sustainable Compliance Programs in Complex Organizations
Authors: Klumpes Paul
Published: February 2024

I identify and test the empirical implications of complexity theory to investigate the effectiveness of the firm’s risk management program in monitoring compliance program activity. I provide a direct link between the quality of Business Regulatory Compliance Unit (which executes and oversees the compliance program implementation) and the overall risk management quality of the firm. I use a multi-method design, incorporating survey questionnaires and econometric multivariate analysis of a sample of European firms. I find a relationship between the risk management exposure of European firms and the quality of their internal control department. I also find a strong relationship between earnings at risk for UK firms and asset-liability at risk for financial firms, but only a weak relationship between cash flow at risk and internal audit quality for European firms. The quality of internal compliance business units is strongly positively related to corporate performance over time.

Authors: Trung Hiep Nguyen , Thi Thuy Hoa Hoang , Phuong Vu Thai
Published: February 2024

Waste bamboo chopsticks encounter limited recycling. Several treatment procedures necessitate sophisticated technologies and intricate processes that need more practicality for local-scale production, leading to substantial challenges in effectively repurposing waste from disposable bamboo chopsticks. In this research, waste bamboo chopsticks were used as raw materials for the production of ball-milled biochar (BM-WBCB). FTIR, SEM, and BET were among the numerous analytical methods used to describe the BM-WBCB. The outcomes showed that the surface was made up of hollow, porous structures. In addition, the pHpzc value of the biochar was 8.7, and it had a BET-specific surface area (273.11 m2 g-1). The study also investigated ball-milled biochar's adsorption capacity and efficiency in removing MB from aqueous solutions. Batch adsorption experiments were conducted under various experimental conditions, such as initial dye concentration, contact time, pH, and adsorbent dose, to evaluate the adsorption kinetics, equilibrium, and thermodynamics of the adsorption process. The results showed the optimal adsorption conditions, such as pH solution, MB concentration, dose of BM-WBCB, and contact time at 10, 30 mg L-1, 0.3 mg, and 60 min, respectively. With a maximal adsorption capacity of 4.2 mg g-1, monolayer adsorption was shown by the fit of the adsorption isotherm data to the Langmuir isotherm model. It was demonstrated that the kinetics of biochar adsorption may be accurately modeled using the linear pseudo-second-order kinetic model.

Published: February 2024

Interest in the study and characterization of aerosols has been growing given its multiple connections with air quality and climate. However, the limited ground-based stations for measurements in many countries are not enough to completely study a big city or a region. Low-cost technology arises as a viable alternative to improve the spatial resolution of measurements. This study aims to demonstrate that the properties of aerosols may change within a megacity and that is advisable to segment measurements according to their characteristics. We measured the optical properties of aerosols in the outskirts of Buenos Aires and compared the data obtained with AERONET data from the city center. This is the first study of its kind in the region. The comparison of concentration, sizes, and types of aerosols shows differences between the sites regardless of the background levels that they share regionally. While the city center has a strong influence from traffic and sea particles and levels of pollution typical of a dense city, the outskirts present several aerosol sources and characteristics of a semi-rural site with a moderate influence of anthropogenic sources.

Women experience menstruation at different ages which makes it difficult for young girls to explain what is happening to their bodies. The lack of information they get from them makes them unprepared and unable to manage their menstruation properly. Thus, teenage girls have feelings of fear, anxiety, discomfort which are signs of anxiety. Anxiety can be reduced by providing interventions in the form of adequate reproductive health education to female students before menarche through video media, presentations, discussions and questions and answers. The experimental approach will be used in this study, with a pre-experimental design and a pretest and posttest one group design. Because the study was conducted on variables for which data did not yet exist, it was necessary to modify the process by administering certain treatments to the research subjects, which were then observed/measured.

La fotografia e il disegno

In vista di stendere alcune riflessioni sull’operato di Gian Franco Di Pietro, in particolare sui disegni e sulle fotografie, mi è parso necessario ripercorrere i suoi testi a partire – perché no – dalla pubblicazione più recente, a dimostrare pienamente, secondo me, il suo sapere di urbanista; è il risultato di una ricerca poderosa sulla Val di Chiana che ripercorre la cronologia della bonifica di questa terra, a sud est della Toscana, tra le province di Arezzo e di Siena.
Architetto di città

La mia conoscenza con Di Pietro è legata fondamentalmente alla scuola, in particolare alla Facoltà di Architettura di Firenze, dove il suo ruolo di primaria importanza era unanimemente riconosciuto. 

Nei primi mesi del 1988, su suggerimento di Antonio Acuto, suo carissimo amico e per me docente di riferimento nel gruppo di ricerca di Guido Canella di cui facevo parte come il più giovane componente, lo chiamai per chiedergli di potermi far conoscere (e valutare) in occasione di una eventuale chiamata a Firenze in seguito al recente concorso nazionale per professori associati.
Sulla casa rurale: una disputa fra amici
Authors: Greppi Claudio

Quando nel 1979 Gian Franco (per gli amici Franco) Di Pietro si mette in viaggio per raggiungere la lontana Cuneo per partecipare al convegno Per una storia delle dimore rurali si trova ad essere l’unico architetto in mezzo a una notevole compagine di medievisti (da Rinaldo Comba, che svolge l’introduzione, a Vittorio Fumagalli, Aldo Settia, Maria Serena Mazzi, Giuliano Pinto), archeologi di diversa estrazione (Riccardo Francovich, Tiziano Mannoni, Diego Moreno, oltre alla geografa-storica Paola Sereno, per non parlare della presenza di un nutrito gruppo di studiosi francesi.
Sorridere sul mondo

L’inizio della lunga, costante, intensa, per taluni versi e in alcuni periodi viscerale, amicizia fra Gian Franco Di Pietro e me risale alla metà degli anni cinquanta. Nell’autunno del 1954 ci eravamo ambedue iscritti alla Facoltà di Architettura di Firenze e poi durante il corso di laurea ci vedevamo quasi quotidianamente. Venendo dalla natia Lugo di Romagna, Franco abitava in affitto a Firenze insieme ad altri studenti.
L'unitarietà di un impegno civile: architettura, insegnamento, urbanistica
Authors: Ventura Paolo
Published: February 2024

Le note che seguono analizzano l’attività di Gian Franco Di Pietro secondo tre campi: l’attività di architetto ed urbanista; l’attività di pianificazione territoriale; la  didattica.

I tre campi sono strettamente interrelati e tra loro complementari. Il primo è quello principale, perché Di Pietro, come i suoi  compagni di corso del tempo, ha una formazione forte di architetto, di specialista della forma fisica dell’ambiente costruito con i propri connotati estetici, costruttivi e funzionali. L’urbanistica, soprattutto quella attuativa, è intesa  come progettazione alla scala più vasta, estensione del campo disciplinare dell’architettura. Di Pietro svolge questa attività da solo o coadiuvato da aiuti di fiducia, in particolare la moglie Lela, mantenendo un proprio controllo personale dai primi schizzi fino al disegno del dettaglio architettonico.
Gian Franco di Pietro, l’attualità di un metodo per una interpretazione integrale del territorio.
Authors: Fanfani David
Published: February 2024

La proposta pervenuta alla redazione di Contesti, ed al Direttore del Dipartimento di Architettura dell’Università di Firenze, di dedicare un numero speciale della rivista alla fi gura di Gian Franco Di Pietro, ha trovato negli interpellati immediata e convinta adesione. Ciò non solo e non tanto come dovuto riconoscimento per un docente che per molti anni ha rivestito e svolto con impegno ed intelligenza un ruolo centrale ed un attività intensa nell’ambito della -un tempo- Facoltà di Architettura; quanto per la ricchezza e valore paradigmatico di un’opera che ha effi cacemente espresso, nell’arco degli anni in cui si è svolta, l’approccio critico rifl essivo, contestuale e multidisciplinare tipico di una buona parte della “scuola fi orentina” di architettura. Approccio necessario, diremmo indispensabile, per cogliere e talvolta rilevare con anticipo i problemi complessi che i fatti territoriali inevitabilmente pongono.
