Multimodal Cardiac Imaging in the Assessment of Patients Who Have Suffered a Cardioembolic Stroke: A Review

Cardioembolic strokes account for 20–25% of all ischaemic strokes, with their incidence increasing with age. Cardiac imaging plays a crucial role in identifying cardioembolic causes of stroke, with early and accurate identification affecting treatment, preventing recurrence, and reducing stroke incidence. Echocardiography serves as the mainstay of cardiac evaluation. Transthoracic echocardiography (TTE) is the first line in the basic evaluation of structural heart disorders, valvular disease, vegetations, and intraventricular thrombus. It can be used to measure chamber size and systolic/diastolic function. Trans-oesophageal echocardiography (TOE) yields better results in identifying potential cardioembolic sources of stroke and should be strongly considered, especially if TTE does not yield adequate results. Cardiac computed tomography and cardiac magnetic resonance imaging provide better soft tissue characterisation, high-grade anatomical information, spatial and temporal visualisation, and image reconstruction in multiple planes, especially with contrast. These techniques are useful in cases of inconclusive echocardiograms and can be used to detect and characterise valvular lesions, thrombi, fibrosis, cardiomyopathies, and aortic plaques. Nuclear imaging is not routinely used, but it can be used to assess left-ventricular perfusion, function, and dimensions and may be useful in cases of infective endocarditis. Its use should be considered on a case-by-case basis. The accuracy of each imaging modality depends on the likely source of cardioembolism, and the choice of imaging approach should be tailored to individual patients.
Maternal Health Risk Detection Using Light Gradient Boosting Machine Approach

Maternal health risk detection is crucial for reducing morbidity and mortality among pregnant women. In this study, we employed the Light Gradient Boosting Machine (LightGBM) model to identify risk levels using data from rural healthcare facilities. The dataset included key health indicators aligned with the United Nations Sustainable Development Goals. The LightGBM model underwent rigorous optimization through hyperparameter tuning and 10-fold cross-validation. Its predictive performance was benchmarked against other algorithms using accuracy, precision, recall, and F1-score, with feature importance assessed to identify critical risk predictors. The LightGBM model demonstrating the highest performance across all metrics. The results underscore the value of advanced machine learning techniques in public health. Future research directions include expanding the demographic scope, incorporating temporal data, and enhancing model transparency. This study highlights the transformative potential of machine learning in maternal healthcare, providing a foundation for improved risk detection and proactive healthcare interventions.
Red onion (Allium ascalonicum L.) skin as an antibacterial on the growth of Staphylococcus aureus

The main bacteria that cause infection in humans is Staphylococcus aureus. Efforts to prevent infectious diseases caused by bacteria can be made by using plant parts that have medicinal potential. One part of the plant that needs to be explored for its potential is the skin of shallot bulbs (Allium ascalonicum L.). This research aimed to determine the effect of red onion skin extract on the growth of S. aureus bacteria. The research design is experimental. The samples in this study were 1 kg of red onion skin and a bacterial sub-culture of S. aureus ATCC: 25923. Extraction was carried out using the maceration method using 96% ethanol solvent and evaporated using a rotary evaporator and water bath. The antibacterial test was carried out by administering 30 µg chloramphenicol (positive control), sterile distilled water (negative control), and red onion skin extract with concentrations of 60%, 65%, 70%, and 75% with 3 repetitions. All treatments were given to S. aureus at 30 µL each using the Kirby-Baeur method. The research instrument was an observation sheet of the diameter of the inhibition zone. Data analysis used One-Way ANOVA. The results of this study show that ethanol extract of red onion skin with concentrations of 60%, 65%, 70%, and 75% was able to produce S. aureus inhibition zone diameters of 3.5 mm, 4 mm, 4.2 mm, and 4.3 mm. The results of the One-Way ANOVA test showed a significance value of 0.15 (sig>0.05), not proven to be able to significantly inhibit the growth of S. aureus. The conclusion shows that red onion skin extract as an antibacterial is not able to significantly inhibit the growth of S. aureus.
Mismatch Responses to Speech Contrasts in Preschoolers with and without Developmental Language Disorder

This study compared cortical responses to speech in preschoolers with typical language development (TLD) and with Developmental Language Disorder (DLD). We investigated whether top-down language effects modulate speech perception in young children in an adult-like manner. We compared cortical mismatch responses (MMRs) during the passive perception of speech contrasts in three groups of participants: preschoolers with TLD (n = 11), preschoolers with DLD (n = 16), and adults (n = 20). We also measured children’s phonological skills and investigated whether they are associated with the cortical discrimination of phonemic changes involving different linguistic complexities. The results indicated top-down language effects in adults, with enhanced cortical discrimination of lexical stimuli but not of non-words. In preschoolers, the TLD and DLD groups did not differ in the MMR measures, and no top-down effects were detected. Moreover, we found no association between MMRs and phonological skills, even though the DLD group’s phonological skills were significantly lower. Our findings suggest that top-down language modulations in speech discrimination may not be present during early childhood, and that children with DLD may not exhibit cortical speech perception deficits. The lack of association between phonological and MMR measures indicates that further research is needed to understand the link between language skills and cortical activity in preschoolers.
Field Expert Assessment on the Inventory of Science Teacher Readiness in Implementing Classroom-based Assessment

Teacher readiness is the willingness of a teacher to implement a programmed Classroom-Based Assessment (CBA) successfully, which is crucial to ensure that a program can be implemented at the individual or organizational level. The readiness of science teachers to implement CBA determines the direction and success of primary school assessments in Malaysia. However, there are limitations in measuring science teachers' readiness to implement CBA. Therefore, there is a need to develop an instrument that can measure the ability. This study was conducted to validate the Science Teacher Readiness Inventory in CBA (ISTRI-CBA) using a Multi-Faceted Rasch Measurement Model (MFRM). A sample of five officers from the Ministry of Education, Malaysia, served as a panel of field experts in assessments, science education, psychometrics, psychology, and language. Based on applying the MFRM, 162 items were retained from an initial pool of 185 items. The panel of field experts was good, with all five having a level of leniency and severity not too far when rating the item across the five dimensions. Expert evaluation using four-point rating scale criteria was used for clarity, accuracy, reasonableness, and brevity. The Results show ISTRI-CBA for the constructs of CBA knowledge, CBA skills, Attitudes, and Professionalism Values were considered unidimensional, while the resource support construct was multidimensional. Overall, the item reliability was satisfactory, ranging between 0.70 to 0.87 and the chi-square value (0.00) was significant, thus demonstrating that the items contained in the Science Teacher Readiness Inventory in the Classroom-Based Assessment dimension have good internal consistency.
Entrepreneurial Marketing Practices and the Performance of Small and Medium Enterprises in Kogi State

Purpose: This study is aimed at the entrepreneurial marketing practices (EMP) and performance of small and medium enterprises (SMEs) in Kogi State.Methodology:A survey research design was used for the study. The researchers gathered data from 208 participants. The data collected were analyzed using descriptive statistics and multiple regression analysis.Findings: Findings showed that SMEs' proactive-ness (PROA) and customer satisfaction have a negative association. However, the relationship is insignificant (p>0.05). Risk-taking (RSKT) and innovativeness (INVT) of SMEs and customer satisfaction have a favorable link that is statistically significant (p<0.05). Implication:The study concludes that SME owners and managers must properly evaluate their EMP, which may be the possible cause of the inability to cope with the dynamic and competitive business climate. The study recommended, among others, that SME owners and managers embrace more innovativeness and risk-taking disposition to achieve improved performance relative to customer satisfaction and combine entrepreneurial marketing skills of risk-taking and innovativeness.
Low-Complexity Downlink Channel Estimation for Millimeter-Wave FDD Massive MIMO Systems

Downlink channel estimation in millimeter-wave (mmWave) frequency division duplex (FDD) massive multiple input multiple output (MIMO) systems is investigated in this letter. Considering the sparse scattering nature of the mmWave channels, the estimation problem is formulated as a sparse parameter estimation problem. A low-complexity orthogonal matching pursuit (OMP) estimation algorithm is proposed by exploiting the inherent correlation in the signal angular domain and the statistical scattering information. Analysis and simulation results verify that the proposed algorithm can achieve more than 90% complexity reduction with comparable or even better estimation performance than the existing OMP-based algorithms.
Seasonal climate summary southern hemisphere (autumn 2010): rapid decay of El Niño, wetter than average in central, northern and eastern Australia and warmer than usual in the west and south

Southern hemisphere circulation patterns and associated anomalies for the austral autumn 2010 are reviewed, with emphasis given to the Pacific Basin climate indicators together with the Australian rainfall and temperature patterns. Autumn 2010 commenced with a rapid decay of El Niño conditions in the Pacific Ocean and a transition to neutral conditions, with most indices suggesting the possibility of La Niña development in subsequent seasons. Australian rainfall was above to very much above average across much of inland Australia, with some locations observing record autumn rainfall. Drier than usual conditions were experienced in southern Tasmania, northern coastal New South Wales and pockets of the Cape York Peninsula this season, whilst the drying trend continued in Western Australia, where rainfall totals in many areas of the Pilbara and Gascoyne districts did not exceed 25 mm. Seasonal maximum temperatures were warmer than average throughout Western Australia, Victoria and Tasmania. In contrast, southern parts of the Northern Territory and Queensland experienced cooler than normal daytime temperatures. Minimum temperatures in autumn 2010 were well above the long-term average in all States and Territories, with overnight temperatures Australia-wide for April ranking as the second warmest on record. Autumn 2010 marked the end of the warmest twelve months on record for Australia following on from an extremely warm winter in 2009.
Value of Water and Soil Conservation in Land Ecosystem in the Guanzhong- Tianshui Economic Zone

Calculation of the value of water and soil conservation is of an important significance for sustainable land use and coordinate ecological and environment development. A case study of calculating the value of water and soil conservation in the Guanzhong- Tianshui economic zone in 1980,2000,2005 and 2010 was carried out based on the remote sensing data,DEM data and statistical data using the geographic information system and remote sensing means. The calculated results showed that the value of water and soil conservation in the Guanzhong- Tianshui economic zone was increased year by year,its increase trend became more significant,and it was increased by2. 54 × 1010yuan during the period from 1980 to 2000,by 1. 56 × 1010yuan during the period from 2000 to 2005,and by 3. 59 × 1010yuan during the period from 2005 to 2010. In which the value of water and soil conservation was high in cultivated land,woodland and meadow,but low in waters,urban and rural construction land and unused land. In addition,there was a positive correlation between the distribution of value of water and soil conservation and vegetation coverage. In order to improve the value of water and soil conservation in the study area,it is suggested to strengthen the protection of basic farmland and woodland and grassland construction,and improve the coverage of woodland and meadow.
Fabrication of low-cost and environmental-friendly EHD printable thin film nanocomposite triboelectric nanogenerator using household recyclable materials

Humans generate massive amounts of plastic and electronic waste, which pollute our environment, particularly our water supplies, and cause fatal difficulties. In addition, the increased use of fossil fuels is wreaking havoc on the ecosystem. In order to solve these issues, we describe a simple, low-cost, and environmentally-friendly triboelectric nanogenerator (TENG) made of electronic waste and recycled plastic, and we add nanomaterial to improve power generation using biomechanical energy. The present investigation involves synthesizing carbon dots (CDs) nano-material through a single-step hydrothermal technique and CDs nano-material characterized via UV.Vis Spectroscopy. The proposed carbon dot-graphite nano composite-based TENGs (CGC-TENGs) are created by reusing dry cells (electronic waste) to obtain graphite, plastic bottles to obtain plastic, and synthesized CDs. CGC-TENGs manufactures a simple, low-cost, and environmentally friendly In-house quick and bulk fabrication printed electro hydrodynamics (EHD) electrospray process that uses less solvent and does not require specialist equipment or knowledge. Comparing fabricate TENG device results, in which CDs used produced high voltage (127.31 V)/current (107.12 μA), while not using CDs produced low voltage (95.23 V)/current (104.12 μA) at similar fabrication parameters, the size of the devices are 4.5 cm × 7 cm, and 15 N force applied. The CGC-TENG (δ) has maximum output performance and is thoroughly investigated using an open-circuit voltage of 171.30 V, a short circuit current of 111.39 μA, and a maximum output power density of 53.08 μW/cm2. CGC-TENG (δ) was used to power an electronic glucose monitoring device, and twenty-three blue light-emitting diodes (LEDs) to demonstrate its practical applications. The approach we propose produces renewable energy sources by reutilizing plastic waste and technological waste, providing a practical and sustainable path toward our goal of creating a green planet.
Influence of Peer Relationship on Self-Consciousness and Social Adaptation of School-Aged Children

This study aimed to assess the influence of peer relationships on the self-consciousness and social adaptation of school-aged children in the Enugu North Local Government Area of Enugu State. A descriptive cross-sectional survey design was used, with a population of 60,780 (29,968 males and 30,812 females). A multi-stage sampling method was employed to select 602 school-aged children from 58 schools in the Local Government Area, forming the sample for the study. For data collection, the study used questionnaires. Data were analyzed with descriptive statistics and inferential statistics. The findings revealed that more than half of the respondents (62.6%) showed moderate social adaptation, particularly when they were with their families (mean score of 4.53±2.31). The majority (76.6%) had low peer relationships, while 80.6% had high self-consciousness. The mean scores for peer relationships, self-consciousness, and social adaptation differed between male and female respondents. Females had higher peer relationships and social adaptation. The mean score for peer relationships was higher among students in private schools compared to those in public schools. A moderate positive relationship was found between peer relationships and social adaptation at a significance level of p<0.05. It is recommended that governmental and non-governmental organizations organize programs to facilitate peer relationships and social adaptation among school-aged children. Furthermore, teachers and parents should be educated to provide support to children in these areas.
A Survey on Digital Image Copy-Move Forgery Localization Using Passive Techniques

: Digital images can be tampered easily with simple image editing software tools. Therefore, image forensic investigation on the authenticity of digital images’ content is increasingly important. Copy-move is one of the most common types of image forgeries. Thus, an overview of the traditional and the recent copy-move forgery localization methods using passive techniques is presented in this paper. These methods are classified into three types: block-based methods, keypoint-based methods, and deep learning-based methods. In addition, the strengths and weaknesses of these methods are compared and analyzed in robustness and computational cost. Finally, further research directions are discussed.
Homogenizing Monthly Rainfall and Temperature Data Series in Maharashtra & Goa

Annual rainfall and temperature data series of all climate stations in Maharashtra & Goa are statistically tested for data homogeneity. To inspect homogeneity of a station, a two-step approach is followed. First, four homogeneity tests Standard normal homogeneity test, Pettit’s test, Buishand’s range test and Von Neumann ration test at 5% level of significance are used to determine test hypothesis for homogeneity on testing parameters of annual rainfall and temperature. Second, results from all these four tests aggregated together into three different classes as ‘useful’, ‘doubtful’ and ‘suspect’. Here 30 rainfall, 29 maximum and minimum temperature climate stations were tested. The results showed 80% stations as ‘useful’, 7% as ‘suspect’ and 13% as ‘doubtful’ for rainfall, for maximum temperature series these results are 17% as ‘useful’, 7% as ‘suspect’ and 76% as ‘doubtful’, while for minimum temperature series these results are 21% as ‘useful’, 10% as ‘suspect’ and 69% as ‘doubtful’. Further, in this study an attempt is also made to correct the monthly rainfall and temperature data series for homogeneity. Stations categorised as ‘useful’ are used as reference series to remove inhomogeneities from ‘suspect’ and ‘doubtful’ stations. To correct rainfall series ratio’s method is used while for temperature series addition method is used. Correction results showed significant improvement in ‘suspect’ category stations. After correction of inhomogeneous series, the results shows all 100% of rainfall stations and more than 65% of temperature stations are now in ‘useful’ category. The corrected stations may be included in further climate research studies.
Basal conditions at the grounding zone of Whillans Ice Stream, West Antarctica, from ice‐penetrating radar

We present a comprehensive ice‐penetrating radar survey of a subglacial embayment and adjacent peninsula along the grounding zone of Whillans Ice Stream, West Antarctica. Through basal waveform and reflectivity analysis, we identify four distinct basal interfaces: (1) an ice‐water‐saturated till interface inland of grounding; (2) a complex interface in the grounding zone with variations in reflectivity and waveforms caused by reflections from fluting, sediment deposits, and crevasses; (3) an interface of anomalously low‐reflectivity downstream of grounding in unambiguously floating areas of the embayment due to basal roughness and entrained debris; and (4) a high‐reflectivity ice‐seawater interface that occurs immediately seaward of grounding at the subglacial peninsula and several kilometers seaward of grounding in the embayment, occurring after basal debris and grounding zone flutes have melted off the ice bottom. Sediment deposition via basal debris melt‐out occurs in both locations. The higher basal melt rate at the peninsula contributes to greater grounding line stability by enabling faster construction of a stabilizing sediment wedge. In the embayment, the low slopes of the ice bottom and bed prevent development of a strong thermohaline circulation leading to a lower basal melt rate and less rapid sediment deposition. Thus, grounding lines in subglacial embayments are more likely to lack stabilizing sediment deposits and are more prone to external forcing, whether from the ocean, the subglacial water system, or large‐scale ice dynamics. Our conclusions indicate that subglacial peninsulas and embayments should be treated differently in ice sheet‐ocean models if these models are to accurately simulate grounding line response to external forcing.
