Published: April 2024

Aiming at the problem that railway supergene geological disaster risk data are scattered and heterogeneous, and it is difficult to unify and centralize management and fusion analysis, the multi-source and heterogeneous supergene geological disaster risk data are standardized and integrated, and based on ontology theoretical knowledge, the digital model of main risk factors such as geography, geology, facilities and meteorology and their relationship is constructed to realize the unified expression of geological disaster riskinformation; Then, a standardized processing method of geological disaster risk data is proposed to realize three-dimensional modeling of geography and geology of railway facilities, and accurately extract multi-factor semantic features of disasters such as location and scope, and gather multi-source dynamic monitoring data such as displacement and meteorology, which provides key data support for scene analysis and visual expression of railway supergene geological disasters. Finally, landslide geological disasters around typical railway lines are selected for experimental verification and analysis, which proves that this method is reasonable and effective.
Biuret doping is used to improve the performance of organic/inorganic photodetectors
Authors: Zhang Qiyue , Hu Yang
Published: April 2024

The combination of inorganic semiconductor materials and perovskite materials can improve the performance and stability of photodetectors, and the photodiode prepared by combining Zinc oxide (ZnO) materials and perovskite materials can realize a wide spectrum detection from ultraviolet to near infrared. As the electron transport layer, ZnO film forming quality is very important to improve the performance of photodetectors. Therefore, in order to improve the film forming quality of ZnO, the surface passivation of ZnO films was prepared by doping Biuret into ZnO precursor solution, and its effects on the device working mechanism and device performance were studied. Studies have shown that doping Biuret improves the film forming quality of ZnO, and thus improves the electron transport capacity of ZnO. Meanwhile, the interface contact between ZnO film and perovskite film is optimized, and the film forming quality of perovskite is also improved. The light detection performance of the photodiode prepared by the combination of ZnO material and perovskite material is greatly improved, and the dark current of the device is obviously reduced, which is about 1/5 of the undoped Biuret device. Compared with undoped Biure device, the doped Biure device obtains the photoresponsivity (R) of 17740 mA/W, an increase of about three times. the specific detectivity (D*) has been increased to 1.27×1013 Jones, an order of magnitude higher than before.
High resolution frequency shift measurement based on the time domain mode-locked optoelectronic oscillator
Authors: Wang Yalan , Xiong Feng , Chen Fengbo , Zhang Jin
Published: April 2024

A high-resolution frequency shift measurement based on the time domain mode-locked optoelectronic oscillator (TDML-OEO) is proposed and experimentally demonstrated. In the proposed approach, the TDML-OEO is firstly excited and the central frequency is selected by injecting a reference microwave signal through an electrical coupler (EC) and used as the reference frequency measurement comb. Then a named unknown microwave signal with various and lower up to even 1 Hz shift compared to the reference microwave signal is injected into the TDML-OEO loop. Due to such a small frequency difference, the central frequency and nearby sidebands will have spectrum aliasing with the reference signal, which is very difficult to be distinguished by low resolution spectrograph. Benefiting from the comb effect, the small frequency difference is enlarged by fine controlling the loop delay time. The proposed method displays high resolution and accuracy due to the comb effect, which will find potential usage in the Doppler radar system for ultra-slow target detection.

Authors: Su Jingjun
Published: April 2024

Background: A large number of traffic accidents are caused by drivers mistakenly stepping on the pedal in emergencies, highlighting an urgent concern about reducing pedal misoperation of drivers. Nowadays, machine learning has been widely applied in the fields of automatic driving, vehicle-circuit coordination, automatic obstacle avoidance, etc. However, the detection technology that focuses on the driver’s driving behavior during driving has not yet been able to greatly reduce the occurrence of traffic accidents. Purpose: Data collected by Chang’an University’s comprehensive driving behavior test platform were used to recognize whether a car driver has the behavior of pedal misoperation by developing and comparing a variety of machine learning algorithms. This paper proposes a method based on machine learning algorithms that takes into account the visual characteristics of the driver to identify pedal misoperation. Research methods: Five different machine learning algorithms were compared for the behavioral judgment of pedal misoperation of drivers through multiple evaluation indexes. Then, the performance of each algorithm was evaluated. As verified, the RandomForest algorithm outperforms all other algorithms with an accuracy rate of 98.4%.Conclusion: According to the research results, a method for recognizing the pedal misoperation behavior of drivers based on the RandomForest algorithm considering visual characteristics can more accurately recognize whether there is a pedal misoperation behavior.

Authors: Yang Zhifei , Mao Bojun
Published: April 2024

The star-shaped concave structure material is a new type of negative Poisson’s ratio material, which combines the advantages of negative Poisson’s ratio material and honeycomb material. The negative Poisson’s ratio structure has very good mechanical properties, such as bearing capacity, impact resistance, and shear resistance. The honeycomb sandwich panel is a typical lightweight material with high specific strength, specific stiffness, and good energy absorption characteristics. In this paper, the star-shaped concave structure is used as the core layer of the sandwich panel, and the advantages of both the honeycomb sandwich panel and negative Poisson’s ratio structure are combined to make a star-shaped honeycomb sandwich panel. In order to analyze the properties of this material, we use the finite element numerical simulation method to study the effects of several geometric parameters (element thickness, beam width, beam length, and star angle) on the bending stiffness, buckling critical load and natural frequency of honeycomb sandwich panels, which provides a new reference for the design optimization of star-shaped concave honeycomb sandwich panels in practical engineering applications.

Authors: Wysocka Magdalena
Published: April 2024

The COVID-19 pandemic has caused a number of disruptions in social and economic life. The introduced restrictions on movement disturbed the fluctuation and efficiency of activities of all entities operating on the market. From day to day, enterprises were closed, and the time, forms and organization of work were changed for employees. Stationary work has been changed to remote work. The article aims to present the results of research on the opinions of employees in terms of preparing them to work in a new form. The research was empirical. The methods of literature studies, diagnostic survey and descriptive statistics were used. The obtained results should be approached critically, because in the opinion of employees, especially those micro and small enterprises, the main manifestation of employers' concern about equipping their home workstations was allowing employees to move computers to their homes. At the same time, nearly every fourth respondent stated that the employer was not interested in the quality of the IT equipment owned by their employee. Nearly every third surveyed employee stated that in their organizations their competences in the field of operating equipment and specialized IT programs facilitating remote work were not strengthened. The conducted research and the content of the article have a theoretical and application value. From the theoretical point of view, they enrich the existing literature on the subject, while the application character manifests itself in showing the management of organizations the expectations of employees. Satisfying these expectations will affect the efficiency of individual work and the entire organization.

Authors:   Sime Darby Technology Centre, Lim C C , Rao V ,   Boh Plantations Sdn. Bhd
Published: April 2024

In this study, DNA markers were used to identify different commercial DxP planting materials. The planting materials were from Sime Darby (SD), MPOB (M), and Felda (F) plus two novel DxP from MPOB coded Porim Series, PS1 and PS2. Six out of the 11 primers tested gave distinct DNA profiles for different materials. Primer A31 gave a unique profile for each of the different types of DxP but there was more similarity between the profiles of the main stream DxP than with the PS type. With primer A36, samples with the same breeding history showed similar DNA profiles. Sime Darby DxP had an almost identical DNA profile to that of MPOB, both of which had much similarity with the profile of Felda DxP. Likewise PS1 and PS2 shared the same DNA profile compared to the other DxP. Five primers did not distinguish the different types of planting materials, generating only 1-2 bands each.

Published: April 2024

Tapping of Hevea brasiliensis for latex is usually accompanied by stimulation. In this study two methods of stimulating clone PB 260 on panel BO-1 tapped on half spiral cut downward on d/4 frequency were evaluated. The preliminary results show that stimulation from eleven rounds with 1.25 per cent ethephon, per year gave yields that were higher than that of the unstimulated control and similar to yields from six rounds of stimulation per year with 2.5 per cent ethephon per year, during the first year of recording. However a sharp decline in yield responses was noted for both stimulated treatments in the second year of recording. The percentage dry cut length was significantly lower during the second year for trees stimulated with 1.25 per cent ethephon (eleven rounds per year) than trees stimulated with 2.5 per cent ethephon six rounds per year. Control and stimulated trees showed no differences with regard to the physiological parameters monitored. Keywords: Clone, drycut length, Hevea brasiliensis, production, stimulation.

Published: April 2024

Plastic pollution has been a serious environmental threat through its increasing application in every field whether it is household or industry. Plenty of plastic in aquatic debris ends up in aquatic environments where it degrades and fragments are nanosized through various ways. These nanoparticles can travel to almost all locations within the organisms via endogenous transport to cause severe damage to them. Among nanoplastics, polystyrene is creating more health hazards in aquatic organisms. Fishes are the best indicator of aquatic pollution as they get exposed to these toxicants by the unscrupulous use of plastic due to its easy applications in personal and public life. In the present study, Heteropneustes fossilis was exposed to various concentrations of polystyrene nanoparticles for 20 days to investigate the histological alterations in the liver under a Scanning Electron Microscope.

Relative range for skewed distributions: a tool for outlier detection
Authors: Dallah Dania , Sulieman Hana , Alzaatreh Ayman
Published: April 2024

The ongoing exploration of outlier detection involves the development and refinement of diverse statistical analysis procedures. In this paper, we examine the performance of the standardized range and relative range in detecting outliers in a skewed data. The proposed approach considers Weibull distribution as a placeholder for skewed data. The empirical construction of the PDFs of the standardized range and relative range from the Weibull distribution along with the simulation work for outlier detection reveal that while the relative range possesses comparable probability behavior to the standardized range, it outperforms the standardized range in detecting outliers from skewed data. Furthermore, the simulated outlier detection framework has been applied to real datasets. The results showed that relative range continue to outperform standardised range in identifying outliers.

BACKGROUND AND AIMS: Pharmacometric in silico approaches are frequently applied to guide decisions concerning dosage regimes during the development of new medicines. We aimed to demonstrate how such pharmacometric modelling and simulation can provide a scientific rationale for optimising drug doses in the context of the Swiss national dose standardisation project in paediatrics using amikacin as a case study.
METHODS: Amikacin neonatal dosage is stratified by post-menstrual age (PMA) and post-natal age (PNA) in Switzerland and many other countries. Clinical concerns have been raised for the subpopulation of neonates with a post-menstrual age of 30–35 weeks and a post-natal age of 0–14 days (“subpopulation of clinical concern”), as potentially oto-/nephrotoxic trough concentrations (Ctrough >5 mg/l) were observed with a once-daily dose of 15 mg/kg. We applied a two-compartmental population pharmacokinetic model (amikacin clearance depending on birth weight and post-natal age) to real-world demographic data from 1563 neonates receiving anti-infectives (median birth weight 2.3 kg, median post-natal age six days) and performed pharmacometric dose-exposure simulations to identify extended dosing intervals that would ensure non-toxic Ctrough (Ctrough <5 mg/l) dosages in most neonates.
RESULTS: In the subpopulation of clinical concern, Ctrough <5 mg/l was predicted in 59% versus 79–99% of cases in all other subpopulations following the current recommendations. Elevated Ctrough values were associated with a post-natal age of less than seven days. Simulations showed that extending the dosing interval to ≥36 h in the subpopulation of clinical concern increased the frequency of a desirable Ctrough below 5 mg/l to >80%.
CONCLUSION: Pharmacometric in silico studies using high-quality real-world demographic data can provide a scientific rationale for national paediatric dose optimisation. This may increase clinical acceptance of fine-tuned standardised dosing recommendations and support their implementation, including in vulnerable subpopulations.
Congenital Duodenal Obstruction: Atresia, Stenosis, and Annular Pancreas
Authors: Alshehri Abdullah
Published: April 2024

Congenital duodenal obstruction, whether complete or partial, occurs due to intrinsic and extrinsic problems during the development of the foetal duodenum; however, it is most often caused by intrinsic duodenal atresia or stenosis. This review will discuss the epidemiology, aetiologies, and classification of congenital duodenal obstruction. The diagnostic approach will be outlined for patients with suspected duodenal obstruction. The therapeutic approach with details of the surgical repair will also be reviewed in light of the best available clinical evidence. The early and late postoperative complications will be discussed as well as the need for reoperation. Outcomes following surgical repair were reviewed.

New blood in the vascular bed after coronary artery bypass grafting (CABG) may represent a turning point between ischemia and normal tissue nutrition. Quality control during CABG preoperatively is essential because errors lead to immediate consequences. With an understanding of hemodynamics, we can now search for less invasive tools for quantification of coronary blood flow changes over time after CABG. Ultrasound is becoming a key player for that purpose and we will present its application. Perioperatively, quality control in CABG should include target selection of native coronary arteries, graft selection, anastomose checking, and long-term flow follow-up. Because some grafts are unreachable for ultrasound evaluation, we should examine both arterial venous sides of coronary circulation. We will present the use of classic, epicardial ultrasonography and TTFM probes by looking for stenoses and competitive flow. We will present our research for quantification of new blood in coronary vessels after CABG. There we found constant increase in flow over the early postoperative period (20% per graft). By increasing graft number, coronary flow increases first linearly and then stepwise. Measured data and trends can be used in ambulatory monitoring and screening of ischemic complications after CABG.

The food azo dye tartrazine (Е102) is not metabolized in humans, and it is excreted unchanged through the kidneys. A study was carried out on the biochemical and histological features in the kidneys of rats, as well as the biochemical features in the blood and urine during long-term use of tartrazine E102 (1 ml of 0.1% solution per 100 g of animal weight daily). In the first experiment, animals received a solution of tartrazine from 1 month up to 3 months age per os; in the second experiment, individuals received tartrazine first transplacentally (in utero), then with mother’s milk, and during 1 month only with food. In the animals of the first experiment, the biochemical changes are not profound, and it is morphologically shown that the losses of the parenchyma and stroma of the kidney are compensated and regenerated. In the second experiment, oxidative stress and signs of chronic glomerulonephritis and chronic tubulointerstitial nephritis were detected against the background of disorders of intrauterine kidney development.
Plant Nutrition Optimization: Integrated Soil Management and Fertilization Practices
Authors: Nogueira de Sousa Rodrigo , Angélica Moreira Lílian
Published: April 2024

This chapter examines soil analysis, fertility management, and integrated soil management (ISM) practices that are critical to sustainable agriculture and environmental stewardship. It highlights the importance of detailed soil analysis—covering physical, chemical, and biological aspects—to inform decisions about fertilization, irrigation, and crop management. The discussion extends to soil nutrient dynamics, emphasizing how accurate analysis identifies imbalances and deficiencies that affect crops. ISM is presented as a holistic strategy that combines multiple dimensions of soil health to improve agricultural resilience. Practices such as conservation tillage, organic matter addition, and crop rotation are shown to increase soil fertility and achieve ecological goals, including biodiversity and carbon sequestration. In addition, the chapter advocates sustainable fertilization within ISM, promoting precision agriculture and 4R nutrient stewardship (right source, rate, time, place) to balance productivity with environmental stewardship. It aims to provide a comprehensive guide to modern soil management techniques that enhance productivity while ensuring soil health and sustainability, and emphasizes the integration of scientific knowledge with practical approaches to address global environmental and food security challenges.
