Authors: Bajrami Albin , Palpacelli Matteo-Claudio , Carbonari Luca , Costa Daniele
Published: March 2024

This study explores the optimization of the TIAGo robot’s configuration for grasping operation, with a focus on the context of aging. In fact, featuring a mobile base and a robotic arm, the TIAGo robot can conveniently aid individuals with disabilities, including those with motor and cognitive impairments in both domestic and clinical settings. Its capabilities include recognizing visual targets such as faces or gestures using stereo cameras, as well as interpreting vocal commands through acoustic sensors to execute tasks. For example, the robot can grasp and lift objects such as a glass of water and navigate autonomously in order to fulfill a request. The paper presents the position and differential kinematics that form the basis for using the robot in numerous application contexts. In the present case, they are used to evaluate the kinematic performance of the robot relative to an assigned pose in the search for the optimal configuration with respect to the higher-order infinite possible configurations. Ultimately, the article provides insight into how to effectively use the robot in gripping operations, as well as presenting kinematic models of the TIAGo robot.
Biomass Estimation with GNSS Reflectometry Using a Deep Learning Retrieval Model
Authors: Pilikos Georgios , Clarizia Maria Paola , Floury Nicolas
Published: March 2024

GNSS Reflectometry (GNSS-R) is an emerging technique for the remote sensing of the environment. Traditional GNSS-R bio-geophysical parameter retrieval algorithms and deep learning models utilize observables derived from only the peak power of the delay-Doppler maps (DDMs), discarding the rest. This reduces the data available, which potentially hinders estimation accuracy. In addition, reflections from water bodies dominate the signal amplitude, and using only the peak power in those areas is challenging. Motivated by all the above, we propose a novel deep learning retrieval model for biomass estimation that uses the full DDM of surface reflectivity. Experiments using CYGNSS data have illustrated the improvements achieved when using the full DDM of surface reflectivity. Our proposed model was able to estimate biomass, trained using the ESA Climate Change Initiative (CCI) biomass map, outperforming the model that used peak reflectivity. Global and regional analysis is provided along with an illustration of how biomass estimation is achieved when using the full DDM around water bodies. GNSS-R could become an efficient method for biomass monitoring with fast revisit times. However, an elaborate calibration is necessary for the retrieval models, to associate GNSS-R data with bio-geophysical parameters on the ground. To achieve this, further developments with improved training data are required, as well as work using in situ validation data. Nevertheless, using GNSS-R and deep learning retrieval models has the potential to enable fast and persistent biomass monitoring and help us better understand our changing climate.

Authors: Gonçalves Fátima Daniela , Martins Jorge M. , Carvalho Luísa H. , Rodrigues José António , Ramos Rui Miguel
Published: March 2024

This work presents a novel application of gas-diffusion microextraction (GDME) for the extraction and identification of volatile carbonyl compounds from a dry-process fibreboard (MDF) by combining high-performance liquid chromatography with diode array detection (HPLC–DAD) and mass spectrometry (MS). GDME is a simple, inexpensive, and environmentally friendly technique that allows the simultaneous extraction and derivatization with 2,4-dinitrophenylhydrazine (DNPH) of selected volatiles. The extraction conditions were optimized using design of experiments through a 24 full fractional design followed by a Box–Behnken design, resulting in 35 min of extraction at 45 °C using 500 µL of DNPH 0.15%. The analysis of commercial MDF samples with different characteristics, such as thickness or colour, showed a distinct emission profile of volatile carbonyls. The principal emitting compounds found were formaldehyde, acetaldehyde, acetone, butanal, pentanal, hexanal, heptanal, octanal, and nonanal. A total of 25 compounds were identified using MS, including saturated and unsaturated aldehydes, ketones, dicarbonyls, and benzaldehyde-derivatives. This method can be a valuable tool for the qualitative evaluation of VOCs released from wood-based panels and for the assessment of indoor-air quality.

Authors: Julich Dorit , Julich Stefan , Feger Karl-Heinz , Klauder Tobias , Zethof Jeroen H. T.
Published: March 2024

During the last decades, forest soils in Central Europe recovered from former sulfur and acid deposition. As external S input into forests has strongly decreased and legacy S pools in the soils are diminishing, internal S cycling through mineralization will increasingly become important for ecosystem nutrition. However, it is not known how microbial biomass is affected by the S pool change in the formerly S surplus soils. Here, we present data on the status quo of C, N, and S in microbial biomass in relation to contents in mineral soil and organic layer. The results of forest soil in Eastern Germany (low and high liming), which is slowly recovering from former pollution, are compared to those of a site remote from air pollution in the Swiss Alps. The contents of C, N, and S in soil as well as in microbial biomass were clearly higher in the organic layer than in mineral topsoil at all sites. Despite the generally low content in the mineral A-horizon, the clean-air site showed indications of a more active S-turnover as compared to the high-pollution site. Liming at the high-pollution site improved the conditions for microbial growth (pH increase) in the organic layer resulting in more mobile S.

Published: March 2024

The literature offers limited information on the effect of obesity on the rate of force development (RFD), a critical parameter for mobility in older adults. The objectives of this study were to explore the influence of obesity on the RFD in older adults and to examine the association between this neuromuscular parameter and walking speed. The participants (42 older adults) were classified into two groups: the control group (CG, n = 22; mean age = 81.13 ± 4.02 years; body mass index (BMI) = 25.13 ± 3.35 kg/m2), and the obese group (OG, n = 20; mean age = 77.71 ± 2.95 years; BMI = 34.46 ± 3.25 kg/m2). Walking speed (m/s) was measured using the 10 m walking test. Neuromuscular parameters of the plantar flexors were evaluated during a maximal voluntary contraction test using a dynamometer. The RFD was calculated from the linear slop of the force–time curve in the following two phases: from the onset of the contraction to 50 ms (RFD0–50) and from 100 to 200 ms (RFD100–200). The gait speed was lower in the OG compared to the CG (p < 0.001). The RFD50/100 and RFD100/200 were lower in the OG compared to the CG (p < 0.001). The RFD50/100 was found to be the predominant influencer on gait speed in the OG. In conclusion, obesity negatively impacts the RFD in older adults and RFD stands out as the primary factor among the studied parameters influencing gait speed.

Published: March 2024

Agriculture is essential for global income, poverty reduction, and food security, with crop yield being a crucial measure in this field. Traditional crop yield prediction methods, reliant on subjective assessments such as farmers’ experiences, tend to be error-prone and lack precision across vast farming areas, especially in data-scarce regions. Recent advancements in data collection, notably through high-resolution sensors and the use of deep learning (DL), have significantly increased the accuracy and breadth of agricultural data, providing better support for policymakers and administrators. In our study, we conduct a systematic literature review to explore the application of DL in crop yield forecasting, underscoring its growing significance in enhancing yield predictions. Our approach enabled us to identify 92 relevant studies across four major scientific databases: the Directory of Open Access Journals (DOAJ), the Institute of Electrical and Electronics Engineers (IEEE), the Multidisciplinary Digital Publishing Institute (MDPI), and ScienceDirect. These studies, all empirical research published in the last eight years, met stringent selection criteria, including empirical validity, methodological clarity, and a minimum quality score, ensuring their rigorous research standards and relevance. Our in-depth analysis of these papers aimed to synthesize insights on the crops studied, DL models utilized, key input data types, and the specific challenges and prerequisites for accurate DL-based yield forecasting. Our findings reveal that convolutional neural networks and Long Short-Term Memory are the dominant deep learning architectures in crop yield prediction, with a focus on cereals like wheat (Triticum aestivum) and corn (Zea mays). Many studies leverage satellite imagery, but there is a growing trend towards using Unmanned Aerial Vehicles (UAVs) for data collection. Our review synthesizes global research, suggests future directions, and highlights key studies, acknowledging that results may vary across different databases and emphasizing the need for continual updates due to the evolving nature of the field.
Blood Pressure Measurement Device Accuracy Evaluation: Statistical Considerations with an Implementation in R
Authors: Chandel Tanvi , Miranda Victor , Lowe Andrew , Lee Tet Chuan
Published: March 2024

Inaccuracies from devices for non-invasive blood pressure measurements have been well reported with clinical consequences. International standards, such as ISO 81060-2 and the seminal AAMI/ANSI SP10, define protocols and acceptance criteria for these devices. Prior to applying these standards, a sample size of N >= 85 is mandatory, that is, the number of distinct subcjects used to calculate device inaccuracies. Often, it is not possible to gather such a large sample. Many studies apply these standards with a smaller sample. The objective of the paper is to introduce a methodology that broadens the method first developed by the AAMI Sphygmomanometer Committee for accepting a blood pressure measurement device. We study changes in the acceptance region for various sample sizes using the sampling distribution for proportions and introduce a methodology for estimating the exact probability of the acceptance of a device. This enables the comparison of the accuracies of existing device development techniques even if they were studied with a smaller sample size. The study is useful in assisting BP measurement device manufacturers. To assist clinicians, we present a newly developed “bpAcc” package in R to evaluate acceptance statistics for various sample sizes.

Snakebite envenoming (SBE) is a neglected tropical disease (NTD). Community-based studies from sub-Saharan Africa are urgently required as data on the incidence are scarce. This study aimed to determine the lifetime prevalence of snakebites in rural Gabon by preparing the conduct of a larger regional survey. A cross-sectional community-based epidemiological survey in Sindara, Ngounie province, was conducted. Households were interviewed about the history of snakebites of household members to calculate lifetime prevalence. In addition, the average annual incidence rate per 100,000 over the last 5 years was calculated. A total of 771 inhabitants were enrolled, of which 5 (0.65%; 95% confidence interval (95% CI: 0.2–1.5%)) were victims of snakebites. Over the past 5 years, annual incidence was 77 bites per 100,000 (95% CI: 0–620). This study provides a first rough estimate of the incidence of SBE from rural central Gabon, demonstrating the importance of this NTD. Key Contribution: The estimated annual incidence of snakebites found was 77 per 100,000. Snakebites occurred mainly during agricultural activities.

Published: March 2024

Knowledge of the antibody response to the third dose of inactivated SARS-CoV-2 vaccines is crucial because it is the subject of one of the largest global vaccination programs. This study integrated microsampling with optical biosensors to profile neutralizing antibodies (NAbs) in fifteen vaccinated healthy donors, followed by the application of machine learning to predict antibody response at given timepoints. Over a nine-month duration, microsampling and venipuncture were conducted at seven individual timepoints. A refined iteration of a fiber optic biolayer interferometry (FO-BLI) biosensor was designed, enabling rapid multiplexed biosensing of the NAbs of both wild-type and Omicron SARS-CoV-2 variants in minutes. Findings revealed a strong correlation (Pearson r of 0.919, specificity of 100%) between wild-type variant NAb levels in microsamples and sera. Following the third dose, sera NAb levels of the wild-type variant increased 2.9-fold after seven days and 3.3-fold within a month, subsequently waning and becoming undetectable after three months. Considerable but incomplete evasion of the latest Omicron subvariants from booster vaccine-elicited NAbs was confirmed, although a higher number of binding antibodies (BAbs) was identified by another rapid FO-BLI biosensor in minutes. Significantly, FO-BLI highly correlated with a pseudovirus neutralization assay in identifying neutralizing capacities (Pearson r of 0.983). Additionally, machine learning demonstrated exceptional accuracy in predicting antibody levels, with an error level of <5% for both NAbs and BAbs across multiple timepoints. Microsample-driven biosensing enables individuals to access their results within hours of self-collection, while precise models could guide personalized vaccination strategies. The technology’s innate adaptability means it has the potential for effective translation in disease prevention and vaccine development.
Railway Bridge Runability Safety Analysis in a Vessel Collision Event
Authors: Bernardini Lorenzo , Collina Andrea , Soldavini Gianluca
Published: March 2024

Bridges connecting islands close to the coast and crossing the sea have been attracting the attention of several researchers working in the field of train–bridge interactions. A runability analysis of a bridge during the event of a ship impact with a pier is one of the most interesting and challenging scenarios to simulate. The objective of the present paper is to study the impact on the running safety of a train crossing a sea bridge as a function of different operational factors, such as the train travelling speed, the type of impacting ship, and the impact force magnitude. Considering train–bridge interactions, a focus is also placed on wheel–rail geometrical contact profiles, considering new and worn wheel–rail profiles. This work is developed considering a representative continuous deck bridge with pier foundations located on the sea bed composed of six spans of 80 m. Time-domain simulations of trains running on the bridge during ship impact events were carried out to quantify the effect of different operating parameters on the train running safety. For this purpose, derailment and unloading coefficients, according to railway standards, were calculated from wheel–rail vertical and lateral contact forces. Maps of the safety coefficients were finally built to assess the combined effect of the impact force magnitude and train speed. The present investigation also showed that new wheel–rail contact geometrical profiles represent the most critical case compared to moderately worn wheel–rail profiles.

Published: March 2024

Purpose: The estimation of the risk posed by malignant polyps for residual or lymphatic disease plays a central role. This study investigated colorectal surgeons’ assessment of these risks associated with malignant polyps.Methods: A cross-sectional questionnaire was electronically administered to colorectal surgeons in Australia and New Zealand in October 2022. The questionnaire contained 17 questions on demographics, when surgeons consider colorectal resection appropriate, and the risk assessment for 5 hypothetical malignant polyps.Results: The mean risk of residual or lymphatic disease that would prompt surgeons to recommend colonic resection was 5%. However, this increased to a mean risk of 10% if the malignant polyp was located in the rectum, and the only resection option was abdominoperineal resection with end-colostomy. There was high concordance between the estimated risk of residual or lymphatic disease by colorectal surgeons and the Association of Coloproctology of Great Britain and Ireland (ACPGBI) guidelines for the 5 hypothetical malignant polyps, with the ACPGBI estimated risk lying within the 95% confidence interval for 4 of the 5 malignant polyps. Nonetheless, 96.6% of surgeons felt that an online risk calculator would improve clinical practice.Conclusion: Colorectal surgeons in Australia and New Zealand accurately estimated the risk posed by malignant polyps. An online risk calculator may assist in better conveying risk to patients.

Nonostante sia spesso banalizzata, la definizione di turismo sostenibile è una nozione complessa e il suo significato è multidimensionale, con significati diversi attribuiti ad essa da diversi stakeholder a seconda del contesto e dei loro obiettivi. Il contributo propone una rilettura critica e schematica della retorica e delle pratiche del turismo sostenibile, in particolare per quanto riguarda i laghi dell’Insubria (nell’Italia settentrionale). Esplora poi un caso di conflitto locale nel quale i risultati degli studi scientifici non vengono presi in considerazione nell’organizzazione e nella pianificazione del territorio, lasciando l’elemento geografico «lago » come oggetto di retorica e controversie.

Authors: Bonjour Théophile
Published: March 2024

Dans la continuité des travaux de Jean-Claude Vernex sur la géographie culturelle des lacs, cet article s’inscrit dans des réflexions récentes sur la notion de limnosystème, définie par Laurent Touchart comme «l’ensemble des interactions naturelles […] et socioculturelles ([ en tant qu’écosystème] possédant une identité culturelle) se produisant sur un territoire centré sur un plan d’eau » . Cette étude propose une description de l’identité culturelle des lacs périalpins sous l’angle sonore. Cette identité sonore a notamment été construite au XIXe siècle par la multiplication des représentations musicales du Bourget et du Léman au moment de l’âge d’or des stations thermales d’Aix-les-Bains et d’Évian-les-Bains. La construction du «son des lacs » est étudiée : d’une part, au moyen de l’analyse d’un corpus de pièces musicales dont les titres évoquent les lacs périalpins ; d’autre part, en faisant la géographie des pratiques musicales thermales dans les territoires lacustres savoyards au XIXe siècle.

Verification of effect of interference between multiple scatterers on the evaluation of backscattering coefficient
Authors: Kutsuzawa Hayato , Hirata Shinnosuke , Yoshida Kenji , Franceschini Emilie , Yamaguchi Tadashi
Published: March 2024

Backscatter coefficient analysis methods for biological tissues have been clinically applied but assume a homogeneous scattering medium. In addition, there are few examples of actual measurement studies in the HF band, and the consistency with theory has not been sufficiently confirmed. In this paper, the effect of correlations among scatterer positions on backscattering was investigated by performing experiments on inhomogeneous media having two types of scattering source with different structural and acoustic properties. In the echo data of phantoms containing two types of scatterer acquired by multiple sensors, the power and frequency dependence of the backscatter coefficient were different from theoretical calculations due to the interference effects of each scatterer. The effect of interference between the two types of scatterer was confirmed to be particularly strong for echoes acquired by the sensor at high intensity and HF, or for a higher number density of strong scatterers.

Published: March 2024

This study aimed to fabricate n-channel four-terminal (4 T) polycrystalline silicon (poly-Si) vertical thin-film transistors (VTFTs) with submicron gate lengths on a glass substrate. The 4 T VTFTs have a poly-Si active layer crystallized via metal-induced crystallization using nickel (Ni-MIC), a top gate (TG), and a bottom gate (BG). Here, the TG covers all the channel regions, and the BG affects only a part of the channel region. A double-gate drive (simultaneous operation of both gates) displayed a high I
on/I
off ratio and small s.s. compared with those of a single-gate drive. In addition, the threshold voltage (V
th) of the TG drive varied depending on the BG voltages (V
BG), with a γ-value (=ΔV
th/ΔV
BG) of 0.17. This value is smaller than the theoretically expected value because of the localized effects of the BG on the channel region and the inferior crystalline quality of the Ni-MIC poly-Si film.

Mela Beşîrê Îlyozî, wekî alimekî edîb li herêma xwe dihat naskirin. Di nav gel da dihat gotin ku berhemên wî yên bi kurmancî hene; çi heye ku heta niha nehatibûn çapkirin û negihaştibûne ber destê xwendevanan. Li ser vê sedemê di vê lêkolînê hewl hat dayîn ku ev edîb digel berhemên wî bihê naskirin. Mela Beşîr, bi tevî ku alimekî edîb ê herêma Torê û Batmanê ye û berhemên wî yên edebî û dînî bi kurmancî hene, heta niha bi firehî bi rêbazeke akademîk xebat li serê nehatîye kirin. Binemala wî ji ku ye, jîyana wî li kê derê derbas bûye û berhemên wî çi ne, bi temamî nahên zanîn. Piştî ku hinek daneyên têkildarî vî mielifî û berhemên wî ji qada lêkolînê hatin berhevkirin, cihê ku ew lê dimîne hat tesbîtkirin, hevpeyvîn pê ra hat kirin û berhemên wî hatin mitalekirin. Li ser bingeha vê xebata sehayî, agadarîyên pêwîst ên têkildarî binemal, bîyografî û berhemên vî edîbî hatin komkirin û li ser van daneyan jî analîza kesayetîya wî ya edebî û berhemên wî hat kirin. Digel xebatên îlmî û xizmetên dînî, wî berhemên edebî û dînî jî bi kurmancî nivîsîne. Mela Beşîr, digel ‘eqîdenameyek, mewlûdek, meqtelnameyek û tecwîdeke bi kurmancî, wî hin helbestên tesewufî û civakî jî bi zimanê erebî û kurmancî hûnane. Ji şêwaza berhemên wî dîyar bû ku wî ji ekolên edebî yên dîroka edebiyata kurdî, daye ser şopa Ekola Aqtepîyan. Digel vê berhemdariya wî ya hêja ku nêzî nîvsedsalekê bi ser da bihûriye jî, hîn yek berhemeke wî nehatîye çapkirin. Heke xebatên akademîk li ser berhemên wî bihên kirin, dê cihê wî di raborîya ekolî ya qonaxên edebîyata klasîk a kurdî da hîn zelaltir bihê tesbîtkirin.

Yogyakarta, a city of culture, has a variety of cultures, including traditional weapons, but these are currently difficult to find. Research has shown that Augmented reality technology can educate the public about the culture of a region, such as the introduction of traditional Yogyakarta weapons through an application that displays 3D objects of traditional Yogyakarta weapons. By utilizing Augmented reality technology in the introduction of traditional Yogyakarta weapons, it becomes a material that is interesting to learn. This application can display 3D objects of traditional Yogyakarta weapons, so that the public can visualize traditional weapons that are currently quite difficult to find. The 3D objects were made based on data from a book published by the Ministry of Education and Culture. The target marker is made in the form of a QR code with a photo of a weapon in the middle, when the marker is detected, a 3D object will appear above it.

ФУНКЦІОНУВАННЯ ВІЙСЬКОВОЇ МУЗИКИ ЗА ЧАСІВ ГЕТЬМАНЩИНИ XVII – ТА ПЕРША ПОЛОВИНА XVIII СТОЛІТТЯ
Authors: Горбаль Вадим , Горбаль Ярослав
Published: March 2024

Мета доповіді полягає в окресленні та розкритті деяких історичних питань, пов’язаних з розвитком військової музики та функціонуванням військового оркестру в Україні періоду Гетьманщини. Методологія дослідження ґрунтується на комплексному підході і полягає у поєднанні методів історизму та джерелознавства. Це дозволяє виокремити військову музику з-поміж інших сфер української музичної культури і сформувати струнку систему її побутування на основі систематизації відомостей з документальних джерел ХVІІ – першої половини ХVІІІ століть та пізніших публікацій. Наукова новизна матеріалів доповіді полягає у спробі виокремити війську музику в самостійну галузь української музичної культури періоду Гетьманщини, яка була пов’язана з історією українського козацтва, і довести, що вона зазнала емансипованого розвитку. У центрі уваги – ратна, генеральна і полкова музика, яка мала офіційно-церемоніальні, службово-стройові, сигнальні (фанфарні), побутово-розважальні та концертні функції. Також вивчено кобзарський рух, що розвивався у козацькому середовищі в найтіснішій кореляції з героїчним козацьким епосом, діяльність полкових музичних цехів та гетьманської капели. У ратній музиці, що звучала під час військових походів, генеральній музиці, яка існувала при гетьмані, і полковій музиці, утвореній при кожному з козацьких полків, наголошено на значенні та функціях духових та ударних інструментів. У висновках зазначено, що бурхливий сплеск військової музики за часів Гетьманщини слід пояснити активною участю українського козацтва у національно-визвольному русі, у численних військових походах, куди українське військо вирушало разом із козацькими цеховими музикантами. Серед пам’яток козацької військової музики маємо унікальну – «Запорізький марш», який і сьогодні звучить як живий музичний образ героїчного часу.
SPONTANEOUS INTRACRANIAL HYPOTENSION – A RARE BUT IMPORTANT CAUSE OF SECONDARY HEADACHE.
Authors: Soni Anand , Soni Namita
Published: March 2024

Spontaneous intracranial hypotension is an uncommon cause of headache. Diagnosis requires high index of suspicion. It
can be easily missed if not considered in differentials. It can be missed on plain MRI if intra venous contrast is not given.
We report Nine cases of spontaneous intracranial hypotension who came with acute to subacute presentation of postural headache. Four patients
were treated conservatively with bed rest and IV uids. These patients were followed up clinically and radiologically. Follow up clinical and MRI
showed complete resolution of symptoms in four conservatively treated patients. Two patients were treated surgically. One patient required
bilateral craniotomy in view of worsening of subdural haematoma. One patient was treated with bilateral craniotomy and epidural blood patch.
Three patients were treated with epidural blood patch alone. All patients except one responded to treatment on follow up. ConclusionSpontaneous intracranial hypotension requires clinical suspicion and a contrast MRI for diagnosis. Conservative trial should be given before
proceeding for epidural blood patch unless there is worsening of symptoms or signs. Duration of observation for conservative treatment before
proceeding for epidural blood patch is individualized. In select subset bilateral craniotomy for subdural haematoma is required along with
epidural blood patch.
