Opinion: Should high-resolution differential mobility analyzers be used in mainstream aerosol studies?
Authors: Fernandez de la Mora Juan
Published: February 2024

Abstract. Differential mobility analyzers (DMAs) are widely used instruments to measure the size distributions of submicron aerosols. High-resolution DMAs (HRDMAs) are defined here as plain DMAs maintaining a steady flow over an unusually broad range of sheath gas flow rates Q. HRDMAs, first developed by Georg Reischl's group, have existed for a long time. However, they have not been widely adopted, except in the size range below 10 nm, often in new particle formation studies. Here we question the commonly held view that HRDMAs are necessarily complex, bulky and expensive machines, mainly of interest in exotic applications outside mainstream aerosol research. Rather, many studies central to aerosol research could be carried out with HRDMAs with considerable advantage in size range, resolution, sensitivity and measurement speed. DMA manufacturers will hopefully take the challenge of developing commercial HRDMAs of complexity and cost comparable to those of today's commercial instruments, adapted for broad use by aerosol scientists, though with greatly improved flexibility and performance. Some of the technical challenges that still need to be overcome are discussed, such as the development of high-flow condensation counter detectors, and the control of high sample and sheath gas flow rates.

Abstract. Understanding the effect of dust upon climate and ecosystems needs comprehensive analyses of the physiochemical properties of dust-emitting sediments in arid regions. Here, we analyse a diverse set of crusts and aeolian ripples (n=55) from various dust-hotspots within the Mojave Desert, California, USA, with focus on their particle size distribution (PSD), mineralogy, aggregation/cohesion state and iron mode of occurrence characterization. Our results showed differences in fully and minimally dispersed PSDs, with crusts average median diameters (92 and 37 µm, respectively) compared to aeolian ripples (226 and 213 µm, respectively). Mineralogical analyses unveiled variations between crusts and ripples, with crusts enriched in phyllosilicates (24 vs 7.8 %), carbonates (6.6 vs 1.1 %), Na-salts (7.3 vs 1.1 %) and zeolites (1.2 and 0.12 %), while ripples enriched in feldspars (48 vs 37 %), quartz (32 vs 16 %), and gypsum (4.7 vs 3.1 %). Bulk Fe content analyses indicate higher concentrations in crusts (3.0±1.3 wt %) compared to ripples (1.9±1.1 wt %), with similar Fe speciation proportions; nano Fe-oxides/readily exchangeable Fe represent ~1.6 %, hematite/goethite ~15 %, magnetite/maghemite ~2.0 % and structural Fe in silicates ~80 % of the total Fe. We identified segregation patterns in PSD and mineralogy differences within the Mojave basins, influenced by sediment transportation dynamics and precipitates due to groundwater table fluctuations. Mojave Desert crusts show similarities with previously sampled crusts in the Moroccan Sahara for PSD and readily exchangeable Fe, yet exhibit differences in mineralogical composition, which could influence the emitted dust particles characteristics.
An Updated Parameterization of the Unstable Atmospheric Surface Layer in WRF Modeling System

Published: February 2024

Abstract. Accurate parameterization of atmospheric surface layer processes is crucial for weather forecasts using numerical weather prediction models. Here, an attempt has been made to improve the surface layer parameterization in the Weather Research and Forecasting Model (WRFv4.2.2) by implementing similarity functions proposed by Kader and Yaglom (1990) to make it consistent in producing the transfer coefficient for momentum observed over tropical region (Srivastava and Sharan 2015). The surface layer module in WRFv4.2.2 is modified in such a way that it contains all commonly used φm and φh under convective conditions instead of the existing single functional form. The updated module has various alternatives of φm and φh, which can be controlled by a flag introduced in the input file. The impacts of utilizing different functional forms have been evaluated using the bulk flux algorithm as well as real-case simulations with the WRFv4.2.2 model. The model-simulated variables have been evaluated with observational data from a flux tower at Ranchi (23.412N, 85.440E; India) and the ERA5-Land reanalysis dataset. The transfer coefficient for momentum simulated using the implemented scheme is found to agree well with its observed non-monotonic behaviour in convective conditions (Srivastava and Sharan 2022). The study suggests that the updated surface layer scheme performs well in simulating the surface transfer coefficients and could be potentially utilized for parameterization of surface fluxes in the numerical weather prediction model.
Toward interpretable LSTM-based modeling of hydrological systems
Authors: De la Fuente Luis Andres , Ehsani Mohammad Reza , Gupta Hoshin Vijai , Condon Laura Elizabeth
Published: February 2024

Abstract. Several studies have demonstrated the ability of long short-term memory (LSTM) machine-learning-based modeling to outperform traditional spatially lumped process-based modeling approaches for streamflow prediction. However, due mainly to the structural complexity of the LSTM network (which includes gating operations and sequential processing of the data), difficulties can arise when interpreting the internal processes and weights in the model. Here, we propose and test a modification of LSTM architecture that is calibrated in a manner that is analogous to a hydrological system. Our architecture, called “HydroLSTM”, simulates the sequential updating of the Markovian storage while the gating operation has access to historical information. Specifically, we modify how data are fed to the new representation to facilitate simultaneous access to past lagged inputs and consolidated information, which explicitly acknowledges the importance of trends and patterns in the data. We compare the performance of the HydroLSTM and LSTM architectures using data from 10 hydro-climatically varied catchments. We further examine how the new architecture exploits the information in lagged inputs, for 588 catchments across the USA. The HydroLSTM-based models require fewer cell states to obtain similar performance to their LSTM-based counterparts. Further, the weight patterns associated with lagged input variables are interpretable and consistent with regional hydroclimatic characteristics (snowmelt-dominated, recent rainfall-dominated, and historical rainfall-dominated). These findings illustrate how the hydrological interpretability of LSTM-based models can be enhanced by appropriate architectural modifications that are physically and conceptually consistent with our understanding of the system.
Spatial-temporal deep learning model based on Similarity Principle for dock shared bicycles ridership prediction
Authors: Zhao Jiahui , Li Zhibin , Liu Pan , Zhang Mingye
Published: February 2024

Demand prediction plays a critical role in traffic research. The key challenge of traffic demand prediction lies in modeling the complex spatial dependencies and temporal dynamics. However, there is no mature and widely accepted concept to support the solution of the above challenge. Essentially,  a prediction model combined with similar objects in temporal and spatial dimensions could obtain better performance. This paper proposes a concept called the Similarity-based Principle (SP), which is applied to improve the prediction performance of deep learning models in complex traffic scenarios. For the temporal components, the long-term temporal dynamics in contemporaneous historical data for ridership are extracted by the Stacked Autoencoder (SAE) method. For the spatial components, the activity-based spatial geographic information (ABG-information) is used to capture the spatial correlation of the traffic network, which is reflected in the daily activities of humans. Specifically, the SP is applied to a Spatio-temporal Graph Convolutional Neural Network (STGCNN) model. In the case study, the  Similarity-based Principle Spatio-temporal Graph Convolutional Neural Network (SP-STGCNN) model predicts demand for bicycle sharing in San Francisco. The results show that the SP effectively improves the model's performance. The prediction accuracy is enhanced by up to 10.34% compared with STGCNN. For spatial relationships, the model using the geographic information attribute performs better than that using the road information attribute and the distance attribute. It is proved that the construction of the Spatio-temporal model-based similarity principle can improve the performance.

Authors: J. A. Moses  , D.S. Jayas  , K. Alagusundaram
Published: February 2024

A non-linear model that can explain three dimensional airflow pressure patterns in bins filled with canola was developed using the finite element method. Resistance to airflow through the porous matrix (canola) was described using a modified form of Darcy’s equation. The airflow model was validated against experimental data obtained from studies conducted in a flat bottom bin of 4.6 m diameter containing‘Tobin’ canola, aerated using a fully perforated floor. The average relative error between the experimental and predicted values for the entire bin geometry was 1.8 per cent. Relative error values decreased with increasing grain bed height and bin diameter. The airflow pressure patterns resulting from eight other duct configurations were simulated. The model can be used to predict the airflow distribution in various grain beds and has the capability to handle variations in product type, moisture content, foreign material content, direction of airflow and aeration duct designs.

Published: February 2024

The study was conducted to standardize the fertigation levels and to find out a suitable drip system layout for okra (Arka Anamika). Initially, trials were conducted to evaluate the efficiency of fertigation and to evolve a suitable and cost effective cultivation practice for okra grown in the humid tropical climate of Kerala during summer season of 2011. It was found that fertigation with 100% of the recommended dose of fertilizer under drip irrigation and plastic mulching gave an average yield of 664g.plant-1, which was almost double when compared to the standard practice with average yield of 296g.plant-1. In continuation, another trial was laid out in 2012 to determine the effect of different fertigation levels. It was found that fertigation with120% of recommended dose (N:P:K@50:8:25 kg.ha-1) gave maximum yield of 421.7g.plant-1, which was at par with that of 100% level of the recommended dose (371.8g.plant-1). Further, a third trial was conducted to standardize the fertigation level needed for irrigated okra.

Published: February 2024

Stunting remains a significant public health concern, impacting physical growth and impeding children's development. Mothers, who play a crucial role in stimulating children's development, often encounter barriers in providing effective stimulation, primarily due to limited access to appropriate resources and information. Online education can bridge this gap by offering easily accessible learning. This aim of this study was to determine the effect of online education on maternal knowledge and attitudes in providing developmental stimulation for stunting toddlers. A quasi-experimental research design was employed, comprising a treatment group and a control group, each consisting of 46 mothers with stunting toddlers, sampled purposively. The treatment group received an online developmental stimulation educational intervention through WhatsApp groups for twelve meetings, each lasting 1.5 to 2 hours. Meanwhile, the control group participated in a stunting assistance program provided by the community health centers (Puskesmas). To compare the knowledge and attitudes between groups, Mann-Whitney and independent Student t-test were used. The assessment of intervention effects on knowledge and attitudes was conducted using Wilcoxon and paired Student t-test within each group. Following the educational intervention on developmental stimulation, there was a significant increase in knowledge; however, there was no significant difference in attitudes. The treatment group (mean score 3.9±1.76) had a higher increase in knowledge scores compared to the control group (2.0±2.25) with a p<0.001. Nonetheless, no significant difference in attitudes was observed between the two groups with the mean change scores was 5.8±15.31 in treatment group and 2.5±18.69 for control group, with a p=0.335. This study suggests that providing online education leads to increased knowledge scores but does not impact attitudes significantly. Additional educational approaches should be considered to enhance maternal attitudes.

Purpose: The European Association of Urology (EAU) classifies patients with prostate cancer into three risk groups - low-risk, intermediate- and high-risk depending on the probability of biochemical progression after treatment with curative intent (either radical prostatectomy or radiotherapy). The aim of the present study is to analyze our experience with patients who underwent radical prostatectomy and to look for the relationship between the pathological results from the operation and the distribution of patients into risk groups. Material/Methods: A single-center, non-interventional study was conducted. The study was performed after analysis of patients undergoing radical prostatectomy (either open or laparoscopic) at the Clinic of Urology in St. Anna Hospital in Varna. The number of patients available for analysis was 201. Data were analyzed with IBM SPSS version 23. Results: We found that high-risk patients had unfavorable results from the examination of the pathology specimens- patients with pT3a and pT3b were more often from the high-risk group. High-risk patients were also at increased risk of PSA progression and development of distant metastases. Conclusions: The EAU-risk groups will probably undergo changes connected with the improved methods for the diagnosis of prostate cancer. But still, it is a valid tool which correctly predicts the unfavorable pathology of the removed specimen and also the risk of biochemical progression after radical prostatectomy.

Published: February 2024

After application in thin-film silicon tandem solar cells and in lab-scale silicon heterojunction (SHJ) devices, doped nanocrystalline silicon (nc) layers now arrived on the industrial stage. Despite their challenging deposition, the benefits they hold with respect to even higher device performance compared to their amorphous counterparts are significant and justify additional effort. In this contribution we report on developments towards industrially applicable processes for n- and p-doped silicon layers, nc-Si(n) and nc-Si(p), and their implementation in SHJ cells. Our investigation focuses on the impact of deposition temperature (Tdep) and the need for a thin oxide layer to promote fast nucleation of thin, sufficiently crystalline, doped nc-Si films in a single deposition chamber powered at 13.56 MHz. We identified main challenges for thin film and contact engineering and reached efficiencies of 23.0% with n- and 23.1% with p-type nc-Si approaching cell performances of our process of record based on amorphous Si (a-Si) layers.

A contemporary view on the significance of the thickness of the retinal nerve fiber layer in the diagnosis of primary open-angle glaucoma
Authors: Karimov M. B. , Makhmadzoda Sh. Q. , Ostanaeva P. M.
Published: February 2024

The provided review reflects the modern methods of early diagnosis of primary open-angle glaucoma applied today, evaluating their positive and negative aspects. One of the diagnostic criteria for glaucoma is the thickness of the retinal nerve fiber layer. A high diagnostic value has been established for determining the thickness of the retinal nerve fiber layer in primary open-angle glaucoma. Literature analysis shows that early diagnosis and treatment of glaucoma at the initial stage of its development are most effective in preventing the progression of the glaucomatous process and exacerbating its course, which can lead to blindness and disability. This underscores the necessity for further refinement and study in this field.

Published: February 2024

Aim: To evaluate the effectiveness of mechano-chemical obliteration in the treatment of varicose enlargement of the great saphenous vein.

Material and Methods: The results of mechano-chemical obliteration of 57 patients (49 (85.9%) women, 8 (14.1%) men; average age 27.2±4.1 years) with varicose disease were analyzed. In 39 patients (36 women and 3 men), the second, and in 18 (13 women and 5 men) – the third class of varicose transformation of subcutaneous veins was observed. The average body mass index of patients was 28.2±2.4 kg/m2, and the average duration of varicose disease was 7.6±1.8 years.

Results and Discussion: The average diameter of the great saphenous vein was 10.4±2.1 mm. Insufficiency of perforating veins with an average diameter of 3.2±0.8 mm was detected in 31 (54.4%) cases. The technical success of the procedure was 100%. No intraoperative complications occurred in any patient. The average duration of mechanochemical obliteration was 24.2±4.8 minutes, and the entire operation – crossectomy, mechano-chemical obliteration, and excision of dilated tributary veins – lasted 98.5±25.5 minutes. The average length of the great saphenous vein subjected to mechano-chemical obliteration was 94.2±6.1 cm. The level of pain on the first day after surgery was 3.8±0.6 points, decreasing to 0.9±0.1 points before discharge. Only on the day after the intervention, patients required narcotic analgesics (average volume of used anesthetics – 1.5±0.5 ml); on other days, patients received non-steroidal anti-inflammatory drugs (average duration 3.5±0.5 days, volume – 10.5±1.5 ml).

Conclusion: Mechano-chemical scleroobliteration is one of the effective methods for eliminating pathological vertical reflux, with its effectiveness observed in the vast majority of patients in the long term.Moreover, due to its minimal invasiveness and capability for repeated application, it can be recommended for widespread clinical use. To improve the results of mechano-chemical obliteration and reduce the frequency of recanalization of the great saphenous vein, it is necessary to supplement the procedure with crossectomy and miniphlebectomy.

Although plastics provide numerous conveniences for human life, concerns about ecosystems and human life are rising tremendously due to increased plastic production and consumption. The ubiquitous presence and undeniable distribution of microplastics (MPs) in agricultural usage created a major risk concern for soil ecology and human health. The ecological risk assessment of microplastics in agricultural sites in the Coimbatore region of South India has been evaluated using three ecological risk indices: Pollution Hazard Index (PHI), Pollution Load Index (PLI), and Potential Ecological Risk Index (PERI). Based on the concentration of hazardous MPs (Polyethylene, polystyrene, polyacrylonitrile, polyacrylamide, polyacrylamide, polypropylene, polyvinyl chloride) in sampling sites, risk assessment indicated the major risk level in inorganic fertilizers applied site. Meanwhile, PLI indicated that all the sites were in category I with low pollution load in the region. However, the hazard scores of polymers increased the PERI values and exhibited their values in the extremely dangerous category. Since the models for evaluating MPs risk in agricultural sites are not yet developed, this calculation is cautiously calculated and further research could gradually add base reference data for understanding the distribution, ecological risk, and trophic transfer of MPs.

An Investigation into the Impact of Pesticides on Ground Water
Authors: Singh Hanumant
Published: February 2024

Agriculture’s irresponsible use of pesticides is an example of a human-caused activity that has contributed to groundwater contamination on a global scale. Prior to the creation of regulatory norms pertaining to pesticide application, the impacts of pesticides on groundwater must be assessed. This research examines the influence of pesticide use on the groundwater aquifer in an agriculturally dominant region of Mount Abu, Rajasthan, India. Using a model called Pesticide Influence Rating Index, a correlation between pesticide uses and its effects on groundwater quality has been developed (PIRI). As an example, five farms in the selected region in the Indian state of Rajasthan were studied. Four pesticides, name dchlorophyrifos, phorate, monocrotophos, and atrazine, were chosen for in-depth examination based on the occurrence of use of different pesticides in the research region. Samples of groundwater were collected and examined for pesticide residual levels. Comparing the measured residues to the PIRI model evaluations revealed that, while the detected standards were greater than the expected standards, the ratio appeared to fluctuate within a constant array. Consequently, multiplicative correction issues were included to the model predictions in order to accurately anticipate pesticide remains in a given region.

Authors: Das Bhagya , Tamuli Jayeeta
Published: February 2024

Farm mechanization is the most recent human innovation to boost food grain output. Following the green revolution, mechanization had a huge influence on output and reduced food scarcity. Today, we live in a time when expanding population has produced a scarcity scenario in which increasing agricultural lands appears to be impossible. Farmers are under pressure to adopt new technology that can enhance food crop production as well as income. Farmers are prioritizing the use of modern mechanized tools and equipment in order to save time, effort, and money. The paper attempts to investigate the influence of mechanization on farmer income. This study will calculate the cost of mechanization for each farm and crop. The mechanization intensity was calculated using several recommended scholars and was found that all randomly selected farms have an average of 1.494 hp/ha and nearly 0.895 kW/ha, requiring additional capital investment to boost power and energy supply to the cultivated areas. This affects farmers’ farm revenue and demonstrates that mechanization is an important component of modern agriculture.

Diabetes mellitus is a chronic metabolic disorder characterized by elevated blood glucose levels, affecting millions of people worldwide. This study aimed to evaluate the potential anti-diabetic activity of Schefflera stellata leaves ethanolic extract in a streptozotocin (STZ)-induced diabetic Wistar rat model. Wistar rats were induced with diabetes using STZ and subsequently treated with Schefflera stellata leaves ethanolic extract. Various biochemical parameters such as fasting blood glucose levels, serum insulin levels, lipid profile, and antioxidant enzyme activities were assessed. Additionally, histopathological examination of pancreatic tissues was performed to evaluate the impact of the extract on structural alterations. The results revealed a significant reduction in fasting blood glucose levels in rats treated with Schefflera stellata extract compared to the untreated diabetic group. Moreover, the extract exhibited a positive influence on serum insulin levels, lipid profile, and antioxidant enzyme activities, suggesting its potential in ameliorating diabetes-induced metabolic dysregulation. Histopathological analysis of pancreatic tissues indicated a preservation of islet architecture in the extract-treated group, highlighting the protective effects of Schefflera stellata against STZ-induced pancreatic damage.

Este estudo relata um caso clínico em que um cão da raça Schnauzer, resgatado e sem histórico médico prévio, foi diagnosticado com urólitos na bexiga, apresentando sinais de disúria e prostração. Durante o procedimento de cistotomia para a remoção dos urólitos, foram identificadas estruturas macroscopicamente compatíveis com um testículo criptorquida na topografia de ovário, caudal ao rim esquerdo, seguido por uma estrutura cilíndrica semelhante ao útero. A avaliação histopatológica posterior revelou que as estruturas eram testículos e útero, este último afetado por endometrite, uma inflamação do endométrio. O paciente foi diagnosticado como um pseudo-hermafrodita macho, caracterizado pela presença de características fenotípicas masculinas, mas com genitálias internas semelhantes às de uma fêmea. Este caso destaca a complexidade do desenvolvimento embrionário e ressalta a importância da avaliação clínica e diagnóstico preciso em situações clínicas incomuns. O tratamento envolveu a excisão das estruturas afetadas e destaca a necessidade de intervenção cirúrgica para tratar tanto os urólitos quanto a endometrite, proporcionando uma abordagem abrangente para o cuidado do animal.

As the demand for secure coding education grows, there is a need for improvements in how secure coding is taught and in preparing students to develop more secure software. As time in a Computer Science classroom is finite, educational efforts should be placed on targeting the most common types of vulnerabilities to better prepare students to avoid common security pitfalls in coding. Existing research in this area mainly focuses on developing vulnerability detection tools rather than analyzing the types of commonly produced vulnerabilities by students. Limited research exists in determining common student-produced vulnerabilities, and the available studies differ from the types of vulnerabilities that are researched in vulnerability detection literature. Our research works to further establish the types of vulnerabilities produced by students by using a static analysis tool on assignment code submissions in an undergraduate Programming II (CS2) course. We present our findings on what types of vulnerabilities are commonly produced by students and contrast them with what is commonly researched in the literature. We find there is little overlap between the vulnerability types reported by our study and other studies in the research area. This research has potential implications for secure coding education in a Computer Science curriculum. Further work should be done to establish the contexts in which specific vulnerability types are more likely to be produced and how to best teach students to avoid producing these vulnerabilities.

Published: February 2024

Students, especially those outside the field of cybersecurity, are increasingly turning to Large Language Model (LLM)-based generative AI tools for coding assistance. These AI code generators provide valuable support to developers by generating code based on provided input and instructions. However, the quality and accuracy of the generated code can vary, depending on factors such as task complexity, the clarity of instructions, and the model’s familiarity with the programming language. Additionally, these generated codes may inadvertently utilize vulnerable built-in functions, potentially leading to source code vulnerabilities and exploits. This research undertakes an in-depth analysis and comparison of code generation, code completion, and security suggestions offered by prominent AI models, including OpenAI CodeX, CodeBert, and ChatGPT. The research aims to evaluate the effectiveness and security aspects of these tools in terms of their code generation, code completion capabilities, and their ability to enhance security. This analysis serves as a valuable resource for developers, enabling them to proactively avoid introducing security vulnerabilities in their projects. By doing so, developers can significantly reduce the need for extensive revisions and resource allocation, whether in the short or long term.
What Is Interesting and Relevant About Cybersecurity?

Published: February 2024

Cyber attacks are a common feature of current news and many of them are the result of easy to avoid vulnerabilities in software. It is imperative that students graduating from an undergraduate Computer Science (CS) curriculum understand the consequences of vulnerable code. When developing lessons and assignments, it would be useful to have a sense of students’ attitude toward cybersecurity and appreciation of the need to write secure code. This paper describes an analysis of the results of a survey of students in core CS courses at our large public university, in which students answer free response questions about what they find interesting and relevant about cybersecurity. The survey was conducted in Fall 2022 and repeated in Spring 2023 after cybersecurity interventions were introduced into several core CS courses. We performed a Natural Language Processing (NLP) analysis of the free response answers to determine the overarching themes in the responses. We found that the most prevalent topics students are interested in are cryptography and penetration testing, and did not change over the two semesters. In answer to the question about the relevance of studying cybersecurity, we found that as students progress through the curriculum, what students find relevant moves from protecting their personal data to its importance in job duties and writing secure programs. When developing lessons and assignments, it may be helpful to introduce cryptography or penetration testing to engage students. Also, students should be taught early and often about the relevance of cybersecurity in their future job duties.
