An Extensive Assessment of the Energy Management and Design of Battery Energy Storage in Renewable Energy Systems
Authors: Onaolapo A. K. , Abe B. T.
Published: May 2024

Many benefits are derivable when renewable energy systems (RES) are integrated with battery energy storage systems (BESS). However, appropriate energy management techniques should be adopted to realize optimal benefits. Many BESS operations’ optimization approaches are available in RES with various techno-economic, environmental, and dispatch-related outputs. BESS operations are optimized using different methods. Past studies have mainly concentrated on certain renewable energy systems designed for specific purposes, such as distributed generation or large-scale. This paper thoroughly examines and analyzes various battery management systems by considering the relationship between the optimization methodology and the intended application. This strategy enables the identification of connections between favored optimization approaches and specific optimization goals. Some approaches are more effective in solving economic goal optimizations, whereas others are commonly used for technical goal optimizations. The selection of the solution methodology is also demonstrated to be highly contingent upon the degree of mathematical formulation of the problem. An analysis is conducted to assess the strengths and limitations of the described optimization techniques. The conclusion is that hybrid approaches, which combine the benefits of multiple techniques, will significantly impact the creation of future operating strategies. This paper provides a comprehensive analysis of optimization approaches and battery applications, aiming to assist researchers in efficiently identifying appropriate optimization strategies for emerging applications in the new generation.
Addressing Counterfeiting and Fraud Concerns in Healthcare Packaging and Labeling with Blockchain: Opportunities and Challenges
Authors: Pesqueira Antonio , Sousa Maria José , Machado Andreia De Bem
Published: May 2024

Blockchain technology (BT), originally developed to facilitate secure digital monetary transactions, has recently gained significant traction in various healthcare sectors. Characterized by the exponential growth of sensitive data, the healthcare sector is poised to witness the emergence of BT. This emergence is primarily driven by the pressing need to globally expose, protect against threats, ensure confidentiality, and establish traceability for the plethora of sensitive data continuously generated by the healthcare industry. The healthcare supply chain focuses on traceability due to the prevalence of counterfeit and recalled drugs. Managing operational constraints such as temperature, humidity, and air quality within specified parameters is paramount. The various processes involved in international trade transactions contribute to the creation of numerous records, each of which is meticulously entered into the systems of the companies involved. Therefore, the problem set for this study was: What are the challenges and prospects for BT in the healthcare sector? To answer this question, the following objective was set: describe and examine the challenges and prospects of BT in the healthcare sector. In addition, a key research objective was to identify specific applications and use cases that can benefit the most from this technological advancement. In line with the research objective, a systematic review of all studies BT for traceability, anti-counterfeiting, and fraud detection was conducted from January 2023 to September 2023. Using robust tools such as VosViewer, we used bibliometric metrics from the renowned medical repository PubMed to construct and visually represent data analysis networks. BT shows remarkable potential to improve traceability and optimize supply chain management within healthcare organizations. The study includes a deep analysis of blockchain capabilities, including smart contracts, identity management, access control, and zero-knowledge proofing.
New task–new results? How the gaze cone is influenced by the method of measurement
Authors: Linke Linda , Horstmann Gernot
Published: May 2024

Perceiving direct gaze — the perception of being looked at — is important in everyday life. The gaze cone is a concept to define the area in which observers perceive gaze as direct. The most frequently used methods to measure direct gaze threshold fall into two broad groups: First, a variant of the method of constant stimuli, firstly introduced by Gibson and Pick (The American Journal of Psychology, 76, 386–394, 1963). Second, a variant of the method of adjustment, firstly introduced by Gamer and Hecht (Journal of Experimental Psychology: Human Perception and Performance, 33, 705–715, 2007). Previous studies found a considerable range of thresholds, and although some influences on thresholds are already known (uncertainty, clinical groups), thresholds often vary for no apparent reason. Another important method is a triadic gaze-perception task, which usually finds triadic gaze direction judgments to be overestimated. In two experiments, we compare the method of adjustment with the method of constant stimuli. Experiment 1 additionally examines the influence of the overestimation effect found in the triadic task. Results indicate that thresholds are larger when measured by the method of adjustment than by constant stimuli. Furthermore, Experiment 1 finds a nonlinear overestimation factor, indicating that gaze directions near 0° are less overestimated than larger eccentricities. Correcting the thresholds with individually obtained overestimation factors widens the gaze cone but does not eliminate the average difference between the methods of adjustments and constant stimuli.

The use of taboo words represents one of the most common and arguably universal linguistic behaviors, fulfilling a wide range of psychological and social functions. However, in the scientific literature, taboo language is poorly characterized, and how it is realized in different languages and populations remains largely unexplored. Here we provide a database of taboo words, collected from different linguistic communities (Study 1,N= 1046), along with their speaker-centered semantic characterization (Study 2,N= 455 for each of six rating dimensions), covering 13 languages and 17 countries from all five permanently inhabited continents. Our results show that, in all languages, taboo words are mainly characterized by extremely low valence and high arousal, and very low written frequency. However, a significant amount of cross-country variability in words’ tabooness and offensiveness proves the importance of community-specific sociocultural knowledge in the study of taboo language.

Published: May 2024

Education in Indonesia has moved towards a broader digital approach. Information and communication technology development has encouraged many schools and educational institutions to look for new ways to integrate technology into teaching. One way is by utilizing a Learning Management System (LMS). One LMS platform that is quite widely used is Schoology. This research aims to find out how Schoology is used in physics learning in schools in Indonesia. The method used in this research is Systematic Literature Review (SLR), namely by finding, selecting, and synthesizing studies submitted for a specific question by following a systematic, transparent, and iterative process. Researchers chose 14 articles sourced from Google Scholar for analysis. These articles are grouped into certain groups to simplify the analysis process. This research found that the use of Schoology is quite good in facilitating physics learning in schools. However, Schoology should not be used in full, educators must play an active role so that students can still understand the material presented. Therefore, the learning method that is suitable for using Schoology in physics learning is the blended learning method.

The cases of kidnapping in Nigeria and in Edo State in particular are rising, and taking dangerous dimensions. What exists in the literature is an ample of research reports on the causes and socioeconomic implications of kidnapping. The general objective of this study is to explore citizens’ perception of the effects of the rising incidence of kidnapping on the security situations in Edo South Senatorial District of Edo State. The exploratory research design operated with the cross sectional research design was adopted for this study.  The calculated sample size for this study was placed at approximately 816. For the collection of qualitative data, the purposive sampling techniques were used to select two interviewees from each of the local government areas. Hence, there were 14 interviewees for the collection of qualitative data that complemented the quantitative data. The majority of respondents (54.7%) believe that the death of victims during kidnappings is avoidable or preventable. There was statistically significant difference in the perception of the level of panic due to kidnapping in Edo South according to the age groups. There is statistically significant association between educational qualification and the tendency to get the Police involved in cases of kidnapping. There was statistically significant difference in perceived police effectiveness in the fight against kidnapping in Edo South according the respondents’ nature of employment. In conclusion, there is a significant number of people who are concerned about kidnapping in their area, with most of affirming a high level of panic due to kidnapping. Kidnapping has a negative impact on society and is a source of fear and concern for many people. The lack of proper security measures adds to the problem, and people are left to take precautions to avoid being kidnapped. The citizens are adjusting to the panic caused by kidnapping by taking practical measures to ensure their safety and seeking solace through spiritual practices. It is recommended that the police should take proactive measures to prevent kidnappings, have the necessary resources and training to handle kidnapping cases, and work with other security agencies and organizations to provide support and services to victims after their release.

Los aceites automotrices residuales son el segundo residuo peligroso más generado en México con un 19.9% del total, debido a un manejo inadecuado de éstos residuos se ven afectados cuerpos de agua, aire y suelo produciendo infertilidad de la tierra, contaminación del aire al ser quemados sin control y en caso de caer a cuerpos de agua se afecta la oxigenación del agua y daños a la flora y fauna acuática. Existe la necesidad de remediar suelos contaminados con aceite residual a través de tratamientos que permita eliminarlo, el lavado de suelos mediante el empleo de surfactantes comerciales es una opción para la remoción de dicho contaminante. En esta investigación se evalúo la eficiencia de remoción empleando detergente líquido foca como un surfactante, para tres distintas concentraciones (1ml, 3ml, 5ml) y a tres distintas velocidades de agitación (1500, 1700 y 2000 rpm). Como resultado del análisis se identificó que la concentración de cinco ml a una velocidad de 1500 rpm presenta mejores condiciones de remoción con un porcentaje de 94.2%. Aunque se emplearon tres distintas cantidades de surfactante y tres diferentes velocidades de agitación, en todos los tratamientos se obtuvieron importantes porcentajes de remoción, las mayores cantidades de eliminación de aceite residual se presentaron a velocidades de agitación baja. Es importante la aplicación de la legislación ambiental mexicana en materia de contaminación de suelos por medio de la inspección a centros de trabajo por parte de las autoridades para realizar el manejo de los aceites residuales de una manera segura.

End-to-End Semi-Supervised Opportunistic Osteoporosis Screening Using Computed Tomography
Authors: Oh Jieun , Kim Boah , Oh Gyutaek , Hwangbo Yul , Ye Jong Chul
Published: May 2024

Background: Osteoporosis is the most common metabolic bone disease and can cause fragility fractures. Despite this, screening utilization rates for osteoporosis remain low among populations at risk. Automated bone mineral density (BMD) estimation using computed tomography (CT) can help bridge this gap and serve as an alternative screening method to dual-energy X-ray absorptiometry (DXA).Methods: The feasibility of an opportunistic and population agnostic screening method for osteoporosis using abdominal CT scans without bone densitometry phantom-based calibration was investigated in this retrospective study. A total of 268 abdominal CT-DXA pairs and 99 abdominal CT studies without DXA scores were obtained from an oncology specialty clinic in the Republic of Korea. The center axial CT slices from the L1, L2, L3, and L4 lumbar vertebrae were annotated with the CT slice level and spine segmentation labels for each subject. Deep learning models were trained to localize the center axial slice from the CT scan of the torso, segment the vertebral bone, and estimate BMD for the top four lumbar vertebrae.Results: Automated vertebra-level DXA measurements showed a mean absolute error (MAE) of 0.079, Pearson’s r of 0.852 (P<0.001), and R2 of 0.714. Subject-level predictions on the held-out test set had a MAE of 0.066, Pearson’s r of 0.907 (P<0.001), and R2 of 0.781.Conclusion: CT scans collected during routine examinations without bone densitometry calibration can be used to generate DXA BMD predictions.

Authors: Ryu Hyun Jin , Leem Da Eun , Yoo Ji Hyun , Kim Tae Hyuk , Kim Sun Wook , Chung Jae Hoon
Published: May 2024

Background: Malignant struma ovarii (MSO) is a very rare disease in which thyroid cancer originates from the ovary. Because it is rare for endocrinologists to encounter patients with MSO, endocrinologists may have a limited understanding of the disease. Therefore, we analyzed and introduced its incidence and clinical course in a tertiary hospital in Korea.Methods: We retrospectively investigated the clinical data of 170 patients who underwent surgery for struma ovarii at the Department of Obstetrics and Gynecology of Samsung Medical Center from 1994 to May 2023.Results: Among 170 patients with struma ovarii, 15 (8.8%) were diagnosed with MSO. The median age of patients with MSO was 48 years (range, 30 to 74), and the median tumor size was 3.3 cm (range, 0.5 to 11.0). Papillary thyroid carcinoma (46.7%) was the most common subtypes followed by follicular thyroid carcinoma (26.7%). All patients were diagnosed after surgery, with no predictions from preoperative imaging. The surgical extent of gynecological surgery was variable. Four patients (26.7%) underwent thyroidectomy for thyroid cancer, while one underwent total thyroidectomy and radioactive iodine therapy for MSO with peritoneal metastasis. Except for one patient who underwent hemithyroidectomy, thyroid stimulating hormone suppression therapy was performed in four patients. Only 53% of MSO patients were consulted by an endocrinologist. With a median follow-up period of 33 months (range, 4 to 156), 11 patients remained disease-free, one experienced progression with peritoneal seeding, and the remaining one was in treatment. There have been no recurrences or deaths due to MSO.Conclusion: An endocrinologist should be involved in establishing a therapeutic plan for MSO, for which the overall prognosis is generally favorable.

Published: May 2024

Heavy metals such as Lead (Pb) in the environment could pose serious reproductive health issues resulting in infertility. Jatropha tanjorensis (JT) from previous studies has been proven to enhance reproductive parameters. This study examined the effects of Jatropha tanjorensis alongside vitamin E on some reproductive parameters in male rats. 40 rats male rats were assigned into 8 groups (n=5): Control, Lead treated group, low dose JT, high dose JT, Vitamin E control, lead + low dose JT, lead + high dose JT, lead + vitamin E groups. Administration was done for 14 days. Mean testosterone level was seen to significantly increase (p<0.05) in all treated groups and vitamin E group in combination with lead when compared to normal control group and Pb control. FSH levels was seen to increase significantly (p<0.05) in all JT treated groups and vitamin E treated group when compared to Pb control but no significant difference was observed when all treated groups was compared to normal control. Also from the study, LH level increased significantly (p<0.05) in high dose JT when compared with every other treated groups. JT and vitamin E administration was able to reduce the negative effect exerted by lead on the various reproductive parameters analyzed.
Socio-cultural practices and improved cooking stove technology choices among agro-pastoral communities in Arumeru District, Tanzania
Authors: Njau Luka , Matto George
Published: May 2024

This study assessed the socio-cultural factors influencing the choice of improved cooking stove technology among agro-pastoral communities in Arumeru District, Arusha region. The study used a cross-sectional research design and was conducted in four villages. Two categories of respondents were involved in the study. The first category consisted of 37 participants interviewed as Key Informants (KIs) and through focus group discussions (FGDs). The second category who responded to the questionnaire involved 92 respondents who had benefited from the alternative cooking energy technologies programme. Both qualitative and quantitative data were collected, with a greater emphasis on qualitative data. Content analysis was used to analyse the qualitative data, while the quantitative data were analysed using Statistical Package for Social Sciences (SPSS) computer software. The study found the persistence of certain socio-cultural practices that encourage the use of traditional three-stone stoves over improved stoves. These practices include preferences for food cooked using traditional three-stone stoves and the tradition of formally handing over the traditional cooking stoves to a newly married woman in the household, among others. It is concluded that while some community members consider these practices positive and valuable, they largely contribute to high biomass consumption and, therefore, the likelihood of environmental degradation. It is recommended that serious sensitisation and training programmes, among other recommendations detailed in this study, be conducted.
The Relationship Between Frank's Sign and Coronary Artery Disease: A Literature Review
Authors: Bostancı Furkan , Yürümez Yusuf
Published: May 2024

Coronary Artery Disease (CAD) is one of the leading causes of death and a significant public health concern. Approaches to early diagnosis of individuals at risk for CAD have always been a subject of research. The Frank sign is one of these approaches. The Frank sign is an independent risk factor for CAD and can be used, especially in the diagnostic process, to identify individuals at risk in the early stages. However, more studies and more extensive series should further support this finding.

Coronal mass ejections (CMEs) are major drivers of geomagnetic storms, which may cause severe space weather effects. Automating the detection, tracking, and three-dimensional (3D) reconstruction of CMEs is important for operational predictions of CME arrivals. The COR1 coronagraphs on board the Solar Terrestrial Relations Observatory spacecraft have facilitated extensive polarization observations, which are very suitable for the establishment of a 3D CME system. We have developed such a 3D system comprising four modules: classification, segmentation, tracking, and 3D reconstructions. We generalize our previously pretrained classification model to classify COR1 coronagraph images. Subsequently, as there are no publicly available CME segmentation data sets, we manually annotate the structural regions of CMEs using Large Angle and Spectrometric Coronagraph C2 observations. Leveraging transformer-based models, we achieve state-of-the-art results in CME segmentation. Furthermore, we improve the tracking algorithm to solve the difficult separation task of multiple CMEs. In the final module, tracking results, combined with the polarization ratio technique, are used to develop the first single-view 3D CME catalog without requiring manual mask annotation. Our method provides higher precision in automatic 2D CME catalog and more reliable physical parameters of CMEs, including 3D propagation direction and speed. The aforementioned 3D CME system can be applied to any coronagraph data with the capability of polarization measurements.

The James Webb Space Telescope (JWST) North Ecliptic Pole (NEP) Time-domain Field (TDF) is a >14′ diameter field optimized for multiwavelength time-domain science with JWST. It has been observed across the electromagnetic spectrum both from the ground and from space, including with the Hubble Space Telescope (HST). As part of HST observations over three cycles (the “TREASUREHUNT” program), deep images were obtained with the Wide Field Camera on the Advanced Camera for Surveys in F435W and F606W that cover almost the entire JWST NEP TDF. Many of the individual pointings of these programs partially overlap, allowing an initial assessment of the potential of this field for time-domain science with HST and JWST. The cumulative area of overlapping pointings is ∼88 arcmin2, with time intervals between individual epochs that range between 1 day and 4+ yr. To a depth of m
AB ≃ 29.5 mag (F606W), we present the discovery of 12 transients and 190 variable candidates. For the variable candidates, we demonstrate that Gaussian statistics are applicable and estimate that ∼80 are false positives. The majority of the transients will be supernovae, although at least two are likely quasars. Most variable candidates are active galactic nuclei (AGNs), where we find 0.42% of the general z ≲ 6 field galaxy population to vary at the ∼3σ level. Based on a 5 yr time frame, this translates into a random supernova areal density of up to ∼0.07 transients arcmin−2 (∼245 deg−2) per epoch and a variable AGN areal density of ∼1.25 variables arcmin−2 (∼4500 deg−2) to these depths.

Published: May 2024

Using deep archival observations from the Chandra X-ray Observatory, we present an analysis of linear X-ray-emitting features located within the southern portion of the Galactic center chimney and oriented orthogonal to the Galactic plane, centered at coordinates l = 0.°08, b = −1.°42. The surface brightness and hardness ratio patterns are suggestive of a cylindrical morphology, which may have been produced by a plasma outflow channel extending from the Galactic center. Our fits of the feature’s spectra favor a complex two-component model consisting of thermal and recombining plasma components, possibly a sign of shock compression or heating of the interstellar medium by outflowing material. Assuming a recombining plasma scenario, we further estimate the cooling timescale of this plasma to be on the order of a few hundred to thousands of years, leading us to speculate that a sequence of accretion events onto the Galactic black hole may be a plausible quasi-continuous energy source to sustain the observed morphology.
Expected Impact of Glints from Space Debris in the LSST

Published: May 2024

We examine the simple model put forth in a recent note by Loeb regarding the brightness of space debris in the size range of 1–10 cm and their impact on the Rubin Observatory Legacy Survey of Space and Time (LSST) transient object searches. Their main conclusion was that “image contamination by untracked space debris might pose a bigger challenge [than large commercial satellite constellations in Low-Earth orbit].” Following corrections and improvements to this model, we calculate the apparent brightness of tumbling low-Earth orbit (LEO) debris of various sizes, and we briefly discuss the likely impact and potential mitigations of glints from space debris in LSST. We find the majority of the difference in predicted signal-to-noise ratio (S/N), about a factor of 6, arises from the defocus of LEO objects due to the large Simonyi Survey Telescope primary mirror and finite range of the debris. The largest change from the Loeb estimates is that 1–10 cm debris in LEO pose no threat to LSST transient object alert generation because their S/N for detection will be much lower than estimated by Loeb due to defocus. We find that only tumbling LEO debris larger than 10 cm or with significantly greater reflectivity, which give 1 ms glints, might be detected with high confidence (S/N > 5). We estimate that only one in five LSST exposures low on the sky during twilight might be affected. More slowly tumbling objects of larger size can give flares in brightness that are easily detected; however, these will not be cataloged by the LSST Science Pipelines because of the resulting long streak.
Viola suavis var. pannonica (Violaceae), a new white-flowered violet from central Europe
Authors: Hodálová Iva , Mereďa Jr Pavol
Published: May 2024

Viola suavis var. pannonica (Violaceae) from central Europe is described here as a new variety to science. It is most similar to the blue-flowered V. suavis var. suavis and the white-flowered V. suavis var. catalonica and V. suavis subsp. naqshii, but exhibits differences in several characters, such as petal colour, spur shape, fimbriae length on the stipules, bracteoles position on the peduncle and lamina sinus shape. Although the new taxon is often considered a colour mutation of V. suavis var. suavis, previous genetic analyses revealed that these white-flowered plants do not arise recurrently at different locations (having multiple origins), but rather form a monophyletic evolutionary lineage. To date, the occurrence of V. suavis var. pannonica has been reported in the Slovak Republic, the Czech Republic and western Ukraine. In this paper, we report its occurrence in Austria and Hungary. Notes on its etymology, distribution, ecology, origin and hybridization, as well as photographs of the new variety (including the holotype) are also provided.

Published: May 2024

The taxonomic status of the Oxynoemacheilus from the Karınca and Havran streams in the north Aegean Basin was evaluated, and it was concluded that these populations contain a new species. The new species, Oxynoemacheilus kottelatisp. nov., is distinguished by a body with a marbled pattern, a deeper caudal peduncle, a shorter caudal peduncle, a wider interorbital distance, and a shorter middle caudal-fin lope. Oxynoemacheilus kottelatisp. nov. is differentiated from the closest species, O. marmaraensis, in possessing 51 nucleotide substitution sites, a genetic distance of 8.40%, the presence of an axillary lobe at the base of the pelvic fin (vs. absent), and a narrower median incision in the upper lip (vs. absent). Three species delimitation tests (ASAP, ABGD, and PTP) and phylogenetic analyses reinforce the validity of O. kottelatisp. nov. as a distinct species.
Global dynamics of a delayed model with cytokine-enhanced viral infection and cell-to-cell transmission

Published: May 2024

Recent studies have demonstrated the superiority of cell-to-cell transmission over cell-free virus infection, and highlighted the role of inflammatory cytokines in enhancing viral infection. To investigate their impacts on viral infection dynamics, we have proposed an HIV infection model incorporating general incidence rates, these infection modes, and two time delays. We derived the basic reproduction number and showed that it governs the existence and local stability of steady states. Through the construction of appropriate Lyapunov functionals and application of the LaSalle invariance principle, we established the global asymptotic stability of both the infection-free and infected steady states.

Objective

We employed machine learning algorithms to discriminate insulin resistance (IR) in middle-aged nondiabetic women.

Methods

The data was from the National Health and Nutrition Examination Survey (2007–2018). The study subjects were 2084 nondiabetic women aged 45–64. The analysis included 48 predictors. We randomly divided the data into training (n = 1667) and testing (n = 417) datasets. Four machine learning techniques were employed to discriminate IR: extreme gradient boosting (XGBoosting), random forest (RF), gradient boosting machine (GBM), and decision tree (DT). The area under the curve (AUC) of receiver operating characteristic (ROC), accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and F1 score were compared as performance metrics to select the optimal technique.

Results

The XGBoosting algorithm achieved a relatively high AUC of 0.93 in the training dataset and 0.86 in the testing dataset to discriminate IR using 48 predictors and was followed by the RF, GBM, and DT models. After selecting the top five predictors to build models, the XGBoost algorithm with the AUC of 0.90 (training dataset) and 0.86 (testing dataset) remained the optimal prediction model. The SHapley Additive exPlanations (SHAP) values revealed the associations between the five predictors and IR, namely BMI (strongly positive impact on IR), fasting glucose (strongly positive), HDL-C (medium negative), triglycerides (medium positive), and glycohemoglobin (medium positive). The threshold values for identifying IR were 29 kg/m2, 100 mg/dL, 54.5 mg/dL, 89 mg/dL, and 5.6% for BMI, glucose, HDL-C, triglycerides, and glycohemoglobin, respectively.

Conclusion

The XGBoosting algorithm demonstrated superior performance metrics for discriminating IR in middle-aged nondiabetic women, with BMI, glucose, HDL-C, glycohemoglobin, and triglycerides as the top five predictors.
