Enhanced the Performance of Solar Photovoltaic (PV) Power Systems Based on ANFIS-MPPT P&O Using A Boost Converter

- This paper introduces the MPPT control method to help PV solar cells reach the maximum capacity thanks to the adaptive ANFIS P&O MPPT algorithm. The power from the PV source through the traditional PI-controlled boost converter has a working point that always follows the MPPT point. Thanks to the ANFIS P&O MPPT algorithm that allows adaptive correction of the perturbation step, the power can quickly reach a new maximum value when the ambient temperature and illuminance fluctuate. The new algorithm also eliminates oscillation around the MPPT’s entire operating point and improves the output voltage quality of the boost converter. The advantage of the adaptive ANFIS P&O MPPT algorithm is confirmed by simulation on MATLAB with a 3.5kW, 100V of the PV system. According to simulation findings, the suggested ANFIS-based MPPT can consistently and efficiently monitor the maximum power point of PV modules under various weather circumstances.
Development of High-Performance Flexible Radiative Cooling Film Using PDMS/TiO2 Microparticles

Radiative cooling, which cools an object below its surrounding temperature without any energy consumption, is one of the most promising techniques for zero-energy systems. In principle, the radiative cooling technique reflects incident solar energy and emits its thermal radiation energy into outer space. To achieve maximized cooling performance, it is crucial to attain high spectral reflectance in the solar spectrum (0.3–2.5 μm) and high spectral emittance in the atmospheric window (8–13 μm). Despite the development of various radiative cooling techniques such as photonic crystals and metamaterials, applying the cooling technology in practical applications remains challenging due to its low flexibility and complicated manufacturing processes. Here, we develop a high-performance radiative cooling film using PDMS/TiO2 microparticles. Specifically, the design parameters such as microparticle diameter, microparticle volume fraction, and film thickness are considered through optical analysis. Additionally, we propose a novel fabrication process using low viscosity silicone oil for practical fabrication. The fabricated film accomplishes 67.1 W/m2 of cooling power, and we also analyze the cooling performance difference depending on the fabrication process based on the measurement and optical calculation results.

White Preservice Teachers and Antiracist Practice: Enabling Trajectories of Learning and Identity in Teacher Preparation

ABSTRACT Preparing white antiracist teachers is an enduring challenge for teacher education. In this article, I demonstrate that white preservice teachers need ongoing access to a full range of learning and identity resources if they are to develop strong connections with antiracism and develop as antiracist teachers. I present data from an 18-month study that illustrates how white preservice teachers’ trajectories of learning and identity are shaped by their access to and engagement with distinct types of learning and identity resources. I discuss the significance of specific resources and identify factors that seem to influence the availability and uptake of such resources by white preservice teachers. I argue that an explicitly resource-rich orientation to preservice teacher learning can be leveraged by teacher educators to ensure that white preservice teachers have access to and engage with the types of resources needed to form a strong identification with antiracist practice and develop the capacity to enact it in the classroom.
Effects of 2-Phenylethanol on Controlling the Development of Fusarium graminearum in Wheat

Applying plant-derived fungicides is a safe and sustainable way to control wheat scab. In this study, volatile organic compounds (VOCs) of wheat cultivars with and without the resistance gene Fhb1 were analyzed by GC-MS, and 2-phenylethanol was screened out. The biocontrol function of 2-phenylethanol on Fusarium graminearum was evaluated in vitro and in vivo. Metabolomics analysis indicated that 2-phenylethanol altered the amino acid pathways of F. graminearum, affecting its normal life activities. Under SEM and TEM observation, the mycelial morphology changed, and the integrity of the cell membrane was destroyed. Furthermore, 2-phenylethanol could inhibit the production of mycotoxins (DON, 3-ADON, 15-ADON) by F. graminearum and reduce grain contamination. This research provides new ideas for green prevention and control of wheat FHB in the field.
Physiological Metrics Across Construction Activity

Safety management and occupational health are essential for construction work. Several studies examine the extent to which physical activity impacts the health and safety of construction workers. To date, however, few studies directly assess the impact of construction activities. This research analyzes physiological and environmental data to explore the impact of construction activity on individual workers, under a range of ambient conditions. Vital signs and physical indicators including heart rate, breathing rate, core temperature, physiological load, mechanical load and posture were collected from a relatively homogeneous set of US Air Force Academy cadets while performing four different construction activities. Results suggest average physiological measures (i.e. mean Heart Rate, Breathing Rate etc.) statistically vary by individual even for individuals similar in age, health, and fitness. Despite individual distinctions, statistical trends and patterns are observable across construction activities. Specifically, the results demonstrate that concrete and asphalt placement are generally more physically demanding, followed by, heavy equipment operation and surveying activities respectively. In addition, the ambient variable, Heat Index, plays a significant role and merits future research. The primary contribution of the research is to demonstrate a method for monitoring and assessing discrete physiological metrics across individuals as well as construction activity.
Upscaled rock-physics templates for seismic reservoir characterization in thin-sand reservoirs

Rock Physics Templates (RPTs) are useful tools for well seismic quantitative interpretation that allow interpreters to understand rock properties variations for a given set of geophysical attributes. RPTs can be used in combination with seismic derived elastic attributes to estimate lithology, porosity and possibly fluid type in the prospective non drilled areas. RPTs are commonly built using rock physics models at log scale. However, depending on seismic data resolution and reservoir thickness, the elastic trend responses may not fall in agreement with the log scale domain. In this work we apply a methodology (Marin and Vera de Newton, 2016) for upscaling RPTs to the seismic frequency using well data from a thin gas shaly sandstone reservoir in the Lower Magdalena basin. Geobody extractions from the seismic inversion derived attributes show how upscaled RPTs allow the identification of thin reservoirs that were not previously detected using the log scale RPTs.
PANDEMIC CRISIS AND FINTECH - MALAYSIAN EVIDENCE

The recent pandemic crisis that occurred across the globe has changed the way human lives including the use of information and communication technologies (ICT). However, the adoption of technology due to the crisis in financial function is still under research, knowing that Malaysia is an emerging country that still lag behind in responding to Industrial Revolution 4.0. Thus, the purpose of this study is to examine the current state of technology adoption by the finance professional and their determinants to adopt technology, specifically financial technology (Fintech) in the workplace. To achieve these purposes, questionnaires were distributed online to collect the information. It comprises three sections namely demographic information, information on respondents’ experience and knowledge on Fintech and finally the factors that affect users’ intention to use Fintech. This research adopted the Unified Theory of Acceptance and Use of Technology (UTAUT) theoretical framework as a theoretical foundation of the study. The findings showed that while the respondents are considered as highly experienced and heavy technology users, they have a moderate knowledge of technology. In addition, performance expectancy, behavioral intention and attitude are the biggest influence for them to adopt Fintech in the workplace. This finding shows that many finance professionals in Malaysia do not refuse to revolutionize their work process by transforming their job tools from manual-based to computerized operation and use more sophisticated devices.
Using the PILOTE Model to Improve Water Productivity for Rice in Rasht, North of Iran

In order to calibrate and validate the PILOTE model for rice in a humid climate, this study was carried in a randomized complete block design with three replications on a popular local variety, Hashemi, during 2001, 2002, 2005, 2006 and 2007 crop seasons. This research was done at the Rice Research Institute of Rasht, Iran. Evaluation of simulated and measured grain yield and dry matter values was done using Nash-Sutcliffe efficiency (EF), Root Mean Square Errors (RMSE) and normalized root mean square errors (NRMSE) indices. The results revealed that RMSE for validation and calibration were 0.69 and 0.72 Mg.ha-1, respectively. NRMSE for calibration was 9.5 % and for validation was 14.1 %. NRMSE for grain yield and dry matter were 8.74 and 13.37 %, respectively. EF values were between 0.84 and 0.98. The results showed that the PILOTE model can be used to manage properly rice irrigation in different regimes. Scenario analysis showed that the best irrigation regime was intermittent irrigation with 8-day interval.
Tools and Methods for Diagnosing Developmental Dysgraphia in the Digital Age: A State of the Art

Handwriting is a complex perceptual motor task that requires years of training and practice before complete mastery. Its acquisition is crucial, since handwriting is the basis, together with reading, of the acquisition of higher-level skills such as spelling, grammar, syntax, and text composition. Despite the correct learning and practice of handwriting, some children never master this skill to a sufficient level. These handwriting deficits, referred to as developmental dysgraphia, can seriously impact the acquisition of other skills and thus the academic success of the child if they are not diagnosed and handled early. In this review, we present a non-exhaustive listing of the tools that are the most reported in the literature for the analysis of handwriting and the diagnosis of dysgraphia. A variety of tools focusing on either the final handwriting product or the handwriting process are described here. On one hand, paper-and-pen tools are widely used throughout the world to assess handwriting quality and/or speed, but no universal gold-standard diagnostic test exists. On the other hand, several very promising computerized tools for the diagnosis of dysgraphia have been developed in the last decade, but some improvements are required before they can be available to clinicians. Based on these observations, we will discuss the pros and cons of the existing tools and the perspectives related to the development of a universal, standardized test of dysgraphia combining both paper-and-pen and computerized approaches and including different graphomotor and writing tasks.
Glucose-sensitive hypothalamic nuclei traced through functional magnetic resonance imaging

Introduction Hypothalamic glucose-sensitive neural circuits, which regulate energy metabolism and can contribute to diseases such as obesity and type 2 diabetes, have been difficult to study in humans. We developed an approach to assess hypothalamic functional connectivity changes during glucose loading using functional magnetic resonance imaging (fMRI). Methods To do so, we conducted oral glucose tolerance tests while acquiring functional images before, and 10 and 45 min after glucose ingestion in a healthy male and cross-sectionally in 20 healthy participants on two different diets. Results At group level, 39 fMRI sessions were not sufficient to detect glucose-mediated connectivity changes. However, 10 repeated sessions in a single subject revealed significant intrinsic functional connectivity increases 45 min after glucose intake in the arcuate, paraventricular, and dorsomedial nuclei, as well as in the posterior hypothalamic area, median eminence, and mammillary bodies. Discussion Our methodology allowed to outline glucose-sensitive hypothalamic pathways in a single human being and holds promise in delineating individual pathophysiology mechanisms in patients with dysglycemia.
Blood Neurofilament Levels Predict Cognitive Decline across the Alzheimer’s Disease Continuum

Neurofilament light chain (NfL) is a potential diagnostic and prognostic plasma biomarker for numerous neurological diseases including Alzheimer’s disease (AD). In this study, we investigated the relationship between baseline plasma concentration of Nfl and Mild Cognitive Impairment in participants who did and did not have a clinically determined diagnosis of dementia by the end of the three-year study. Additionally, we explored the connection between baseline plasma concentration of NfL and AD dementia patients, considering their demographics, clinical features, and cognitive profiles. A total of 350 participants from the Biomarker of AmyLoid pepTide and AlZheimer’s diseAse Risk (BALTAZAR) multicenter prospective study were investigated: 161 AD dementia participants and 189 MCI participants (of which 141 had amnestic MCI and 48 non-amnestic MCI). Plasma biomarkers were measured at baseline and the progression of clinical and cognitive profiles was followed over the three years of follow-up. Baseline plasma NfL concentration increased across the Alzheimer’s disease continuum with a mean NfL value of 17.1 ng/mL [SD = 6.1] in non-amnestic MCI, 20.7 ng/mL [SD = 12.0] in amnestic MCI, and 23.1 ng/mL [SD = 22.7] in AD dementia patients. Plasma NfL concentration correlated with age, body mass index (BMI), and global cognitive performance and decline, as measured by the Mini-Mental State Examination (MMSE). MMSE scores decreased in parallel with increasing plasma NfL concentration, independently of age and BMI. However, NfL concentration did not predict MCI participants’ conversion to dementia within three years. Discussion: Baseline plasma NfL concentration is associated with cognitive status along the AD continuum, suggesting its usefulness as a potential informative biomarker for cognitive decline follow-up in patients.
Stable posture tracking for modular spatial hyper-redundant serial arms using selective control points

ABSTRACT Robotic arms with redundant degrees of freedom are known to exhibit characteristics that make them more suitable than their non-redundant counterparts in many manipulation tasks. These redundant degrees of freedom allow for multiple control objectives to be pursued simultaneously leading to increased efficiency, dexterity and versatility. Redundancy however brings about structural complexity, difficulties in tasks specification, challenging kinematics and dynamics and high computational cost. This work tackles kinematic hyper redundancy resolution in the context of posture (shape) control of a modular serial link arm by proposing a new take on formulating and solving the problem. In the proposed formulations, strategic points along the arm (termed control points) are explicitly controlled in such way that their overall motion steers the posture of the arm toward the desired target posture. These control points stem from the modular structure of the arm and are chosen in order to achieve specific control characteristics. Desired target posture outlines are specified intuitively and arbitrarily with continuous spline curves. The proposed method has demonstrated the ability to safely steer the arm towards intermediate postures which reduce the overall posture tracking error. It copes well with singularities and is capable of tracking target postures that are significantly distinct from the arm's initial posture. Numerical simulations on a 40 DOF arm are conducted to assess the validity and performance of the method. GRAPHICAL ABSTRACT

Effectiveness of constructivist e-learning module in General Biology

With the need for improved learning materials for General Biology becoming increasingly evident, this study developed a constructivist e-learning module and evaluated its effectiveness for teaching senior high school STEM students. The module, anchored in the 5E Instructional Model (engage, explore, explain, elaborate, and evaluate), was implemented in a blended instruction setting for 81 senior high school STEM students. This module distinguishes itself from traditional e-learning modules by emphasizing student-centered learning and experiential engagement through hands-on activities, problem-solving, and peer collaboration. Pretest and posttest were used to assess content mastery and cognitive skills performance. Mean, standard deviation, and paired t-test were used to describe the scores and significant differences between the scores. The posttest scores revealed a significant increase in both content mastery and cognitive skills performance. The constructivist e-learning module effectively enhances student engagement, content mastery, and cognitive skills development while aligning with curriculum of Philippine Department of Education (DepEd) and can be seamlessly integrated into existing classrooms.
Recent earthquake sequences at Coso: Evidence for conjugate faulting and stress loading near a geothermal field

Abstract Two recent earthquake sequences near the Coso geothermal field show clear evidence of faulting along conjugate planes. We present results from analyzing an earthquake sequence occurring in 1998 and compare it with a similar sequence that occurred in 1996. The two sequences followed mainshocks that occurred on 27 November 1996 and 6 March 1998. Both mainshocks ruptured approximately colocated regions of the same fault system. Following a comparison with the background seismicity of the Coso region, we have detected evidence of stress loading within the geothermal field that appears to be in response to the 1998 earthquakes. The M L = 5.2 mainshock in the 1998 sequence occurred at 5:47 a.m. UTC and was located approximately 45 km north of the town of Ridgecrest in the Coso range. The mainshock of the 1996 sequence had an M L magnitude of 5.3. There have been no observable surface ruptures associated with either of these sequences. Though the mainshocks for both sequences were located about 900 m apart and have nearly the same local magnitudes, the sequences differ in both their temporal and spatial characteristics. An analysis of the fault-plane solutions of the mainshocks and the aftershock locations suggests that the two sequences ruptured fault planes that are perpendicular to one another. We observe a much faster temporal decay of the 1998 sequence compared to the one in 1996; moreover, while the 1996 sequence was not followed by any sizeable (i.e., M L > 4.0) aftershocks, the 1998 sequence had four such events. From an estimate of the tectonic stressing rate on the fault that produced the 1998 sequence, we infer a repeat cycle of 135 years for an earthquake of comparable magnitude at Coso.
What Affects Crop Production in Pakistan: The Role of Agriculture Employment, Machinery and Fertilizer Consumption

Labor abundant or under developing economies normally rely on their agriculture sector. The performance of agriculture sector depends on the production of cropping, livestock, fishery, and forestry sectors. The contribution of both cropping and livestock sectors in the agriculture production is almost 96.42 percent while the cropping sector contributes almost 33.85 percent during the fiscal year 20-2021 [Pakistan Economic Survey, 2020-2021]. The focus of this study is to investigate the factors which may influence the performance of crop production in Pakistan. For this purpose, bounds testing approach for the sample period from 1976 to 2022 is considered. The empirical results reveal that employment in agriculture sector, agriculture machinery, fertilizer consumption and urban population significantly boost the pace of crop production while the role of raw material imports is witnessed to be insignificant. The above reported results proposes that utilization of latest agriculture machinery, advanced fertilizers and high employability in agriculture sector may be encouraged to uplift the share of cropping sector in agriculture production in Pakistan.
