Published: April 2024

Context. The paper considers the problem of automating the creation of an annotated dataset for further use in a system for detecting, localizing and classifying blood cells in an image using deep learning. The subject of the research is the processes of digital image processing for object detection and localization.
Objective. The aim of this study is to create a pipeline of digital image processing methods that can automatically generate an annotated set of blood smear images. This set will then be used to train and validate deep learning models, significantly reducing the time required by machine learning specialists.
Method. The proposed approach for object detection and localization is based on digital image processing methods such as filtering, thresholding, binarization, contour detection, and filling. The pipeline for detection and localization includes the following steps: The given fragment of text describes a process that involves noise reduction, conversion to the HSV color model, defining a mask for white blood cells and platelets, detecting the contours of white blood cells and platelets, determining the coordinates of the upper left and lower right corners of white blood cells and platelets, calculating the area of the region inside the bounding box, saving the obtained data, and determining the most common color in the image; filling the contours of leukocytes and platelets with said color; defining a mask for red blood cells; defining the contours of red blood cells; determining the coordinates of the upper left and lower right corners of red blood cells; calculating the area of the region within the bounding box; entering data about the found objects into the dataframe; saving to a .csv file for future use. With an unlabeled image dataset and a generated .csv file using image processing libraries, any researcher should be able to recreate a labeled dataset.
Results. The developed approach was implemented in software for creating an annotated dataset of blood smear images
Conclusions. The study proposes and justifies an approach to automatically create a set of annotated data. The pipeline is tested on a set of unlabelled data and a set of labelled data is obtained, consisting of cell images and a .csv file with the attributes “file name”, “type”, “xmin”, “ymin”, “xmax”, “ymax”, “area”, which are the coordinates of the bounding box for each object. The number of correctly, incorrectly, and unrecognised objects is calculated manually, and metrics are calculated to assess the accuracy and quality of object detection and localisation.

Context. Consideration of a set of examples of practical application of the procedure for identifying overflow of the bit grid of a computer system operating in a non-positional number system in residual classes. The object of the study is the process of processing data represented in the residual class system.
Objective. The goal of the work is to consider and analyze examples of the bit grid overflow definition of a computer system when implementing the operation of adding two numbers in a system of residual classes based on the application of a method for determining the bit grid overflow, based on the use of the concept of number rank.
Method. The specificity of the functioning of a computer system in a system of residual classes requires the implementation of not only modular operations, but also requires the implementation of additional, so-called non-modular operations. Non-modular operations include the operation of determining the overflow of the bit grid of a computer system in the system of residual classes. In a non-positional number system in residual classes, implementing the process of detecting overflow of the bit grid of a computer system is a difficult task to implement. The method considered in the work for determining the overflow of the bit grid is based on the use of positional features of a non-positional code of numbers in the system of residual classes, namely the true and calculated ranks of a number. The process of determining the overflow of the result of the operation of adding two numbers in the system of residual classes has been studied, since this arithmetic operation is the main, basic operation performed by a computer system.
Results. The developed methods are justified theoretically and studied when performing arithmetic modular operations of addition, subtraction and multiplication using tabular procedures.
Conclusions. The main advantage of the presented method is that the process of determining the overflow of the bit grid can be carried out in the dynamics of the computing process of the computer system, i.e. without stopping the solution of the problem. This circumstance makes it possible to reduce the unproductive expenditure of the computer system in the system of residual classes. In addition, this method can be used to control the operation of adding two numbers in the residual class system. This increases the reliability of obtaining the true result of the operation of adding two numbers in the system of residual classes.

Background: Acute coronary syndrome (ACS) is defined by the abrupt reduction or total obstruction of blood flow to the myocardium. Recognized risk factors for ACS include conditions such as hypertension, dyslipidemia, smoking, obesity, diabetes mellitus, hyperuricemia, as well as variables like age, gender, and family history of the ailment. The objective of this research was to examine the prevalence and importance of modifiable risk factors associated with ACS.
Material and Methods: The study is structured as a prospective case-control study. The research sample comprises 100 ACS patients, categorized into three groups: STEMI, NSTEMI, and UAP. The Chi-Square test and logistic regression were used to examine the samples. The threshold for statistical significance was set at p<0.05.
Results: ACS occurred more frequently in male patients (54%) and those aged ≥ 40 years (85%). Several factors demonstrated significant associations with ACS, including smoking habits, dyslipidemia, hypertension, diabetes mellitus, obesity, and hyperuricemia. Among these, inpatient ACS was notably linked with obesity (OR: 7.42; 95% CI: 1.48-37.11; p=0.015) and hypertension (OR: 0.13; 95% CI: 0.03-0.53; p=0.005). The presence of ACS was also correlated with a notable increase in inpatient care, with obesity and hypertension emerging as risk factors for inpatient ACS.
Conclusion: ACS was more common in males and individuals aged 40 or older, with significant associations identified between ACS and various factors, including smoking, dyslipidemia, diabetes, obesity, hyperuricemia, and hypertension, with obesity and hypertension specifically linked to inpatient ACS.

Authors: Ataei Abtin , McManamon Paul , Sarangan Andrew 
Published: April 2024

In this study, a Traveling-Wave Mach-Zehnder intensity Modulator (TW-MZM) was designed and optimized for six different electro-optical (EO) crystals: Lithium Niobate (LNB), Potassium Niobate (KNB), Lithium Titanate (LTO), Beta Barium Borate (BBO), Cadmium Telluride (CdTe), and Indium phosphide (InP). The performance of each EO crystal, including optical and radio frequency (RF) loss, applied voltage, and modulation bandwidth, was estimated and compared. The results suggested that, in theory, KNB, LTO, BBO, and CdTe have the potential to outperform LNB. However, it should be noted that the loss associated with KNB and LTO is comparable to that of LNB. The findings demonstrated that BBO and CdTe exhibit a modulation bandwidth exceeding 100 GHz and demonstrate the lowest loss among the considered crystals based on the assumed geometry.

Published: April 2024

Day by day, the share of renewable energy-based power plants such as offshore wind farms and photovoltaic power plants, in the present-day power systems is escalating. Nevertheless, most of these power-producing facilities have been located quite far away from the load centers. At this stage, HVDC power systems provide satisfactory options due to qualities such as reduced line losses, substantial controllability, and environmental advantages. Nevertheless, unique converter designs are required to combine asynchronous HVDC networks with each other and with already existing high voltage alternating current (HVAC) networks. In this study, based on the above special cases, a unique DC-DC modular multilevel converter (MMC) architecture is presented that provides an excellent solution for both integrating modern asynchronous HVDC networks and integrating these modern HVDC power systems with existing asynchronous HVAC power systems. The mathematical analysis of the recommended DC-DC MMC design has been examined in detail and the power transfer between two asynchronous power grids has been realized in a simulation environment. Efficient bilateral power transmission has been made achievable by the control system. The recommended DC-DC MMC topology has shown to be a highly successful approach, in the interconnection of HVDC power systems, according to the simulation results.

Published: April 2024

Background:
Open fractures, a common consequence of road traffic collisions, are associated with a high risk of complications. The introduction of standard guidelines has been shown to improve patient care and reduce the risk of complications in several countries. In September 2021, the Malawi Orthopaedic Association/Arbeitsgemeinschaft für Osteosynthesefragen Alliance (MOA/AOA) guidelines and standards for open fracture management were introduced in Malawi. This study aimed to assess the management of open fractures in hospitals in Malawi, before and after implementing a training course on the MOA/AOA open fracture guidelines.

Methods:
This was a descriptive and quantitative, before-and-after study that reviewed the medical files of patients with open fractures at Zomba Central Hospital and Mulanje, Salima, and Mangochi district hospitals over two 3-month periods. Variables included initial assessment; antibiotic prophylaxis; place of debridement; type of anesthesia; treatment of the open fracture in the emergency department, operating room, and wards; and short-term complications requiring hospital treatment.

Results:
A total of 88 open-fracture case files were reviewed; 43 were prior and 45 were subsequent to the implementation of the open fracture guidelines. The overall median patient age was 36 years (interquartile range, 27 to 45 years), and 91% (80) were male. Limb neurovascular status assessment and documentation improved from 26% (11) of the patients before the guidelines to 62% (28) afterward (p = 0.0002). The percentage who underwent debridement in the operating room significantly increased from 19% (8) to 69% (31) (p = 0.01). The percentage who underwent debridement under general or spinal anesthesia significantly increased from 5% (2) to 38% (17) and from 12% (5) to 29% (13), respectively (p= 0.001). The wound infection rate decreased from 21% to 11%, but this was not significant, and there was no change in the overall complication rate (p = 0.152).

Conclusions:
This study suggests that training on the MOA/AOA open fracture management guidelines followed by their implementation can lead to at least temporary improvement in the management of open fractures. Nevertheless, additional studies need to be performed to understand the effect on long-term patient outcomes.

Levels of Evidence:
Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
