The rapidly growing demand for vast numbers of Internet of Things (IoT), in both urban and rural areas, necessitates their ceaseless and automatic energy supply. This is particularly vital in cases where the IoT sensors are deployed in inaccessible locations outside of human reach. In this direction, unmanned aerial vehicles (UAVs) with wireless power transfer (WPT) capabilities can solve this issue, due to their flexible deployment. To this end, we devise an architecture in which a UAV swarm covers the energy demand of an IoT network, while at the same time, the UAVs fulfil their energy needs through a charging station (CS) infrastructure. A practical energy model is considered, which takes into account the battery levels of the UAVs, energy consumption due to transition to different locations, hovering, and WPT. Also, to capture the UAV-CS interaction, an economic model is introduced. The UAVs aim to maximize their profit by transferring energy to the IoT, while the CSs aim to maximize their profit by recharging the UAVs. To ensure a profit-wise stable CS-UAV association, while providing energy coverage to the IoT, we formulate a many-to-one matching game. Due to inter-dependencies between UAVs’ utilities, i.e., externalities, a matching algorithm based on peer effects and two- sided exchange-stability is proposed. To further evaluate the con- sidered system, we design an optimization scheme which performs the UAV-CS assignment with the aim to maximize the energy coverage of the IDs. Numerical results showcase the matching algorithm’s ability to provide near-optimal energy coverage to the IDs, while balancing fairness among the competing agents’ profit, compared to the optimization scheme.

Published: May 2023

Respiration and heartbeat are among the important vital signs of living beings. Taking advantage of the physical attachment of lung and heart, measurements of both can be performed simultaneously using airflow rate microsensors to measure the respiration airflow. For such airflow rate sensors, the packaging is crucial to define and encapsulate the airflow region. In this study, we propose a facile packaging technique for flexible airflow rate microsensor. The thermal calorimetric sensing structure was fabricated through a standard microfabrication technology on a thin polyimide film. The film was packaged at the center of a resin tube utilizing its buckling. We also proposed an approach to improve the time response by limiting the thermal capacity around the sensing structure through the implementation of a thin substrate for the sensing structure supported by a thicker film. The strategy successfully improved both the time response and sensitivity of the airflow rate sensor. Finally, the utilization of the sensor for simultaneous respiration and heartbeat measurement was demonstrated through an animal experiment using a small animal, namely rat.
A Comparative Study of Physics-Informed Machine Learning Methods for Modeling HVAC Systems
Authors: Nguyen Tung L. , Nghiem Truong
Published: May 2023

Machine learning (ML) methods have been used to model complex dynamical systems, such as heating, ventilation, and air conditioning (HVAC) systems, to overcome the difficulty and high cost of modeling these systems using physical principles. However, ML-based methods often require large amounts of data, have poor generalization performance, and lack physical consistency. Physics-informed machine learning (PIML) has recently been introduced to overcome these drawbacks by incorporating physical laws into learning. There is, however, an unmet need to evaluate commonly used PIML methods to demonstrate their benefits and compare their performance in practical applications. In this comparative study, we evaluated various PIML methods and physical properties for modeling HVAC systems using real data. We considered physics-informed neural network methods and constrained Gaussian process methods, as well as physical properties that can be easily obtained in practice, such as smoothness, boundedness, and monotonicity. Our results showed the substantial benefits of PIML in improving model accuracy and data efficiency, and allowed us to compare the different PIML methods and physical properties to provide meaningful conclusions and recommendations for applying PIML in practice.

360 Degree Real Time Risk Assessment of Business for Reliable Supply Chain Operations - Business Credibility Product
Authors: Sahoo Asit Kumar , Srigiriraju Harish
Published: May 2023

Currently, small and medium-sized businesses often rely on outdated financial data and anecdotal information to assess their business risk. Large organizations may use historical financial statements and ratings provided by rating agencies, which are paid by these institutions, leading to a lack of efficiency and accuracy in assessing business credibility. This can prevent SMBs from becoming suppliers to large companies, accessing working capital credit, and increase the risk of fraud or delinquency in transactions with large corporations. To address this issue, I have developed a Business Credibility Product that uses real-time data feeds from various sources, including banking, eCommerce, payroll, payments, commercial real estate, telecom, utilities, insurance, tax filing, and firmographic data. The product includes a comprehensive 360 degree evaluation of a company's credibility, as well as a deep dive into each of the contributing factors to identify significant deviations and trends. This allows for real-time portfolio monitoring and improved lending, verification, and supply chain operations.

Published: May 2023

Introduction: The World Health Organization (WHO) defined primary bone lymphoma as a single bone lesion with or without regional lymph node involvement or multiple bone lesions without distant visceral or lymph node involvement. It is a rare entity; indeed, primary bone lymphomas represent 1-3% of non-Hodgkin's lymphomas, 5% of extra-nodal non-Hodgkin's lymphomas and 3% of primary bone tumors [2, 3]. Objective: The objective of our work is to clarify the imaging of a rare entity of primary bone lymphoma in a 6-year-old boy, who had been complaining for 1 month of pain in his right lower limb without functional impotence. Case Report: A 6 year old boy, who had been complaining for 1 month of pain in his right lower limb without functional impotence or other associated signs. The clinical examination revealed a child in good general condition, apyretic, with a limp when walking, limitation of all the articular amplitudes of the left he knee, a swelling of the homolateral thigh with discreet quadricipital amyotrophy. Examination of the lymph nodes did not identify any adenopathies. Standard radiographs of the left knee showed multiple lesions involving the lower extremities of the femur and the upper extremities of the tibia, with confluent intraspongiosa and areas of osteocondensation associated with localized cortical fracture without periosteal reaction. The biological workup revealed no abnormalities, including an LDH in the normal range. An MRI of the right thigh was requested for a better characterization of the lesion and to establish a locoregional extension assessment. It showed a large epiphyseal-metaphyseal lesion process of the lower end of the femur and epiphyseal-metaphyseal of the upper end of the left tibia in T1 hyposignal, locally infiltrating T2 heterogeneous hyper signal with vascular enclosure and popliteal ADPs. The CT scan was requested as part of the extension work-up and did not reveal any secondary lesion. The patient underwent a bone ........

Published: May 2023

Introduction: Xanthogranulomatous cholecystitis is a rare condition with a specific symptoms. The main differential diagnosis is vesicular adenocarcinoma. It can be revealed by abdominal pain, hemorrhage or fistulas. We report here the case of a patient with xanthogranulomatous cholecystitis revealed by febrile abdominal pain. We report a case of xanthogranulomatous cholecystitis in a 45 year old woman, revealed by febrile abdominal pain. Case Report: The patient was 45 years old and had no particular pathological history. She presented with acute febrile abdominal pain. The clinical examination revealed a conscious patient, hemodynamically and respiratorily stable, febrile (fever 39°C), with abdominal defence of the right hypochondrium, the rest of the examination was without anomaly. An abdominal CT scan was requested urgently revealing a circumferential and regular parietal thickening of the gallbladder, hypodense with spontaneous contrast enhanced after injection of PDC measuring 12 mm of maximum thickness, with individualization of multiple fissured calculi, seat of air bubbles realizing the sign of "Mercedes-Benz sign", It is associated with an important infiltration of the mesenteric fat of the neighborhood. A complementary MRI scan with T1, T2, Diffusion, 3DMRCP sequence was performed, showing a parietal thickening in T1 hyposignal, T2 intermediate signal, diffusion hypersignal, multiple liquid structures in T2 hypersignal associated with multiple stones in signal void on all sequences, and a dilatation of the main bile duct measuring 13 mm upstream of a regular eccentric stenosis of the lower bile duct with an inflammatory appearance. Discussion and Conclusion: Xanthogranulomatous cholecystitis is a pathology that is difficult to diagnose preoperatively, as it can be mistaken for a vesicular adenocarcinoma. CT and MRI scans can sometimes help to clarify the diagnosis, particularly in the presence of a diffuse and continuous thickening of the wall with a con

Introduction: Cerebral aspergillosis is a rare and very severe pathology, usually affecting immunocompromised patients, for whom early antifungal treatment is necessary. Because of the clinical and microbiological diagnostic difficulty, brain imaging is crucial for the positive and differential diagnosis. However, the scannographic and MRI appearance is not very specific, as aspergillosis lesions classically present as multiple rounded images, with or without a hemorrhagic component, with or without annular enhancement after contrast injection. Diffusion imaging may present a more specific aspect and help in early diagnosis. Case Report: The patient was 48 years old and had been followed for 4 months for positive HIV infection at the AIDS stage. She presented with a sudden onset of HTIC syndrome (headache, vomiting and confusion) in a febrile context.On admission, the clinical examination found a stable patient on the HD and respiratory plan, BMI: 16 kg/m2, polypneic at 28cpm, febrile at 39°the other constants are normal (FC: 90 b/mn, BP: 11/8 cmHg, FR: 28 c/mn. The somatic examination was without particularities. The biological workup showed white blood cells at 14900 (PNN: 13800) and CD4 lymphocytes at 45/mm.The evolution was marked by the occurrence of acute respiratory distress 3 days later with an elevated D-Dimer level of 740 µg/L. A thoracic angioscan was performed to rule out pulmonary embolism. Aspergillosis serology was performed: positive. The diagnosis of cerebral aspergillosis by dissemination from the pulmonary focus was retained. The patient died within 24 hours. Conclusion: Morphological imaging of cerebral aspergillosis lesions is not very specific. Knowledge of their appearance on diffusion imaging (global restriction of water diffusion or heterogeneous "target" appearance) can provide valuable assistance in the positive and differential diagnosis of aspergillosis.

Published: May 2023

Hanjeli is one of the alternative food crops that are high in nutrients, healthful, easy to grow, and adaptable to a wide range of environmental circumstances. Due to the limited understanding of people who believe Hanjeli is a wild plant or weed, usage of this commodity is still quite low in Indonesia. To save and prevent the loss of genetic resources, it is vital to study, inventory, and characterize Hanjeli so that plant breeders can use it to create greater varieties in the future. The goals of this study are to: (1) learn about the existence and types of Hanjeli plants in West Sumatra Province; (2) collect Hanjeli germplasm; and (3) learn about the morphological diversity and level of similarity of Hanjeli plants as a starting point for germplasm conservation of Hanjeli plants in West Sumatra. This study took place in four districts/cities in West Sumatra Province from June to November 2021. This study is carried out using a survey method with purposive sampling. The NTSYSpc2.02i application is used to present morphological data descriptively and for similarity analysis. 69 Hanjeli accessions were discovered throughout the exploration process. Hanjeli grows between 6 to 1575 meters above sea level and can thrive in a variety of environments, including arid ground and regions near water sources (starting on the outskirts of streams to the edges of rice fields). For all characters, the phenotypic similarity study of Hanjeli plants yielded similarity coefficients ranging from 0.67 to 1. At 0.67, the accessions were divided into two groups: 66 accessions in the first group, and 3 accessions in the second group.

Published: May 2023

Due to the extreme weather that hit throughout the year resulted in the threat of rice plants falling down. It was known that the fall of rice plants was a limiting factor for obtaining high yields and quality of grain. Therefore, it was considered important to evaluate the resistance to fall in the general methods of planting rice in the area. Those were transplanting planting (TP) and direct seed planting (TBL). Based on this objective, we identified the morphophysiology of rice stems in the laying factor of 2 planting methods commonly used by farming communities, namely transplanting planting and direct seed planting. Identification was carried out by observing the morphology and physiology of the rice stalks, the laying index and the level of fall of rice plants in each planting method (TP and TBL). The result of the research was that the direct seed planting method (TBL) tends to show morphophysiological identification results that were not resistant to falling compared to the transplanting method (TP). The laying rate shown by TBL was accounting for 75.5% while transplanting (TP) was only 5.7% of the experimental unit area. Significant differences were observed in plant height, stem length, center of gravity height, laying index, laying level, stem internode length, stem internode width, bending moment and bending stress of the stem. In the experiment, it was also found that the grain was damaged due to the fall of the rice plant when the rice fields were flooded. Therefore, it is important to carry out agronomic management as part of sustainable mitigation of the risk of falling rice plants to support national food security

Armyworm (Spodoptera exigua Hubner.) is the main pest of acacia. Controlling such pests generally uses synthetic insecticides, which cause negative impacts such as they would resistance & resurgence, environmental pollution, residual effects, secondary pest explosions, and reduced biodiversity. We need an alternative in pest control, such as using parasitoid Trichogramma japonicum. This study aims to test the parasitism after the release of Trichogramma japonicum on Spodoptera exigua eggs in Acacia crassicarpa nurseries. The research was carried out at the Kerinci Central Nursery PT. RAPP on October 2019-March 2020. The research started with exploring, rearing and releasing parasitoid Trichogramma japonicum. The treatment was plotted with and without releasing Trichogramma japonicum on Spodoptera exigua eggs for seven days of observation and analyzed using T-test at a 5% level. The significance of  Trichogramma japonicum parasitized eggs in Spodoptera exigua eggs was 41.9% after releasing parasitoids in Acacia crassicarpa nurseries. The highest parasitization by Trichogramma japonicum was in the 3rd plot with an average parasitization of 53.8% and the lowest was in the 1st plot with an average 31.3% parasitization. Trichogramma japonicum that emerged from the total mass of eggs brought to the laboratory after parasitized eggs were 14.2%. Trichogramma japonicum showed significantly different results in reducing the egg population of Spodoptera exigua in the mother plant nursery Acacia crassicarpa.

Apart from being a source of energy, rice is also a source of protein and microelements that are useful for human health, such as B vitamins, iron (Fe), zinc (Zn), anthocyanins, and folic acid. Blast disease caused by the fungus Pyricularia oryzae is an important disease in rice crops worldwide. The aim of the study was to evaluate the resistance of nutritionally specific rice lines to blast disease. The nutritionally specific rice tested were preliminary yield lines and multilocation trials. The pathogens of P. oryzae used were 4 races, namely races 173, 133, 073 and 033. Observations and analysis of resistance to blast disease were carried out based on the IRRI SES method. The results for the preliminary yield trial line showed that the B15068C-MR-1-2-7-KN-2 line showed a resistant response to 4 races of blast pathogen with a disease scale of 1 and as many as 11 special rice lines showed a resistant response or moderately resistant to 4 races, while the multilocation trial lines obtained as many as 3 special rice lines and the variety of Inpari 19 which had a resistant or moderately resistant response to 4 races of P. oryzae. These nutritionally specific rice lines can be used as gene donors for resistance or proposed as varieties that have blast disease resistance. while the multilocation trial lines obtained as many as 3 special rice lines and the variety of Inpari 19 which had a resistant or moderately resistant response to 4 races of P. oryzae.

Observation is one of the stages in the selection to obtain the expected rice lines to be tested at the yield and multi-location testing stage as candidates for breeding rice varieties. The research was carried out at the Tamanbogo Lampung Experimental Garden in the 2021 planting season (MT) using an augmented design with five replications of comparison varieties: Inpago 8. Inpago 12, Inpago 13. Situbagendit, and Situpatenggang. As many as 247 promising breeding rice lines were used as materials in this experiment with their respective advantages. Each line was planted with a 0.9 m x 5 m plot size with a spacing of 30 cm x 15 cm. Fertilizer used is 300 kg/ha NPK + 100 kg/ha Urea. Weeding is done twice, precisely at the time before the next fertilization I and II. The observations include 50% flowering age, harvest age, plant height, tiller quantity, dry-milled grain yield, and resistance to biotic and abiotic stresses. The analysis of variance showed that the genotype significantly affected plant height and productive tiller quantities. High heritability and genetic advances in plant height characters indicate that this character is a selection criterion so that selection can be made to increase these characters. The comparison varieties significantly affected the character of plant height and productive tiller quantities. From this activity, 37 breeding lines were obtained with higher yields than the comparison varieties.

Composting or decomposition is a method of processing solid waste which has a high content (70% -80%). Empty fruit bunches from the processing of Crude Palm Oil Factories and fronds of palm oil (TM) plants have the potential to be used as organic fertilizer. Composting without a decomposer takes a long time of seven months, so a bio activator is needed to speed up the process. Research with the aim of determining the influence of various bio activators in accelerating the composting of palm fronds and empty bunches has been carried out at PT. Bahana Karya Semesta unit of Sungai Air Jernih Estate, Pauh, Sarolangun, Jambi in November 2021-February 2022. The Research method used was a Complete Randomized Design (RAL) with two factors. The first factor is bioactivator consisting of four types such as LCPKS (liquid waste from crude palm oil factory), MOL (Local microorganism), EM4 (Effective microorganism 4) and cow dung. The second one is the compost material consisting of empty fruit bunch/EFB (5 kg), fronds (5 kg), EFB + fronds (2.5 kg + 2.5 kg), EFB + fronds + LCC (legume cover crop) (2 kg + 2kg + 1kg). C/N ratio, temperature, campiness, shrinkage, crumbly, and color of compost were also recorded. The results showed that the bio activator could decompose organic material with some of the parameters that we measured. The analysis of the C/N ratio showed that each treatment gave different results. Palm fronds + LCPKS had the highest C/N ratio of 91, meanwhile, the combination of EFB+cow dung showed the lowest C/N ratio of 23. The material of EFB + fronds + LCC showed the highest pH value of 6.36 and the highest compost depreciation of 57.48%. The variety of compost material has the same influence on the temperature, campiness, and color of the compost. Meanwhile, the type of bio activator had the same effect on temperature, pH, shrinkage, crumbly, and color of the compost.

Deforestation or functional change from forest to non-forest plays a role in changing ecosystems and species within it. Insects as one of the faunas in it is an interesting aspect to be studied, especially ants. The research was conducted in Nagari Gunung Selasih and Sungai Kambut, Pulau Punjung District, Dharmasraya Regency, West Sumatra from November 2017 to January 2018. This study aims to determine the diversity of ants in the palm oil plantation ecosystem bordering the forest ecosystem. This research takes the form of a survey where the Purposive Random Sampling method was used for points sampling. Hand Collecting, Bait Trap, and Pitfall Trap sampling methods were applied for each plant. Identification of the samples obtained was carried out at the Animal Taxonomy Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Andalas University, Padang. Total ants (Hymenoptera: Formicidae) collected during the study were 3,046 individuals consisting of 5 subfamilies, 15 genera, and 29 species. The most dominant species was Anoplolepis graciliphes, followed by Odontoponera denticulate and Odontomachus simillimus. Based on the results of the study, it can be concluded that the level of abundance and diversity of ant species is not directly affected by the distance from the forest ecosystem, but it is strongly influenced by the composition of environmental factors such as temperature, humidity, light intensity, altitude, and management of existing habitats and vegetation.
