Path tracking with switchable stability constraints for vehicle collision avoidance based on extended stability region

There is a certain conflict between vehicle stability and the performance of path-tracking under emergency conditions. In this paper, to make full use of the lateral capacity of vehicles, a path tracking method with switchable stability constraints is proposed. First, using the Lyapunov energy equation and Hurwitz’s theorem, the lateral stability region (SR) and the critical steering angle of steady steering at different longitudinal speeds are calculated. Based on this, the extended stability region (ESR) and the extended critical steering angle of the vehicle under the control of an additional yaw moment are obtained. Furthermore, the driving area during collision avoidance is divided into unsafe and safe areas, and based on the model predictive control strategy, a path-tracking controller with switchable stability constraints is established. In the unsafe area, the vehicle states are allowed to break through the SR temporarily, and to ensure path-tracking accuracy, the ESR is taken as the stability constraint. In the safe area, the stability constraint is switched to the SR, and to make the vehicle states quickly return to SR, a regain stability controller is established. Finally, a Simulink-CarSim simulation and a hardware-in-the-loop (HIL) experiment are conducted. The simulation results show that a balance between tracking effect and vehicle stability can be effectively achieved through the proposed path-tracking system under the investigated emergency conditions. The real-time performance of the proposed control strategy is validated through the HIL experiment.

A response surface equation for the drag polar for an airplane flying in the vicinity of wavy sea surface

The drag polar equation is the key issue to calculate the performance-based parameters during various flight phases and determine the optimum conditions. This is an essential feature to be included in airplane flight control system to manage the flight. The aircraft under certain emergency conditions are instructed to land on sea water. This underlines the combinational role of ground effect and the surface wave shape on airplane aerodynamic responses. Up to now, many investigations have described the airfoil and wing aerodynamic behaviors near the ground but none was devoted to an airplane flying near a wavy surface. In this paper, intensive numerical simulations have been carried out on a general aviation airplane flying near the water wavy surface. The effects of ground proximity as well as the wave amplitude have been investigated on airplane 2D longitudinal forces and moment. Some limited wind tunnel tests have also been performed on the same model, in the vicinity of water surface to validate the numerical calculations. A statistical quadratic equation based on Response Surface Model, RSM, has been proposed for the airplane flying in the vicinity of the wavy water in which, the wave shape deterioration due to both the airplane flowfield and the viscous dissipation has been taken into account. The statistical measures approve the model quality and accuracy in comparison to the numerical simulation data. The results show that the oscillations in aerodynamic forces are strong functions of the wave amplitude. The time variations of both CL and CD follow the shape of the surface wave while it does not have any remarkable effect on their mean values.

Unraveling the Narrative of Orbital Cellulitis as a Sequelae to Trauma

Abstract Orbital cellulitis is often seen as a serious complication of acute rhinosinusitis. Facial trauma is one of the possible causes of orbital cellulitis. A middle-aged man, a mason by occupation, presented to ENT OPD following a facial trauma. He presented with a laceration over the right zygomatic region with right-sided periorbital swelling and redness. Wide-spectrum antibiotics were initiated for the patient. Pus was drained daily, and surgical debridement of the wound followed by sterile dressing of the wound cavity was done regularly until the pus discharge totally stopped. The patient was taken for secondary suturing and was discharged after that. However, the patient lost to follow-up. Facial trauma is a cause of orbital cellulitis. Orbital cellulitis is an emergency condition and requires urgent medical attention. Adequate antibiotic therapy is of utmost importance to treat the condition. Surgical care is advisable if the medical line of management fails.

Surface Deformation Analysis by Fusion of Multi-temporal and Multi-source Data under Disaster Emergency Conditions

Abstract. Rapid analysis of surface deformation is crucial for rescue operations following natural disasters. However, the lack of recent terrain data and the discrepancy between data types and field-collected data often hinder timely surface deformation analysis. To enhance data usability, this paper proposes an analytical method that integrates multiple sources of remote sensing data, including satellite data, oblique photography data, and LiDAR data. By merging oblique images with grayscale point clouds, true-color point clouds are generated. The method optimizes old data through threshold segmentation and median filtering, then converts and unifies the resolution of multi-source data via data interpolation. Elevation interpolation matrices are employed for overlay analysis, and a combination of bilateral filtering and threshold processing is used. This groundbreaking approach enables the completion of surface deformation analysis in emergency geospatial surveys and has been validated in various typical regions, demonstrating its application potential across different surface environments. Experimental results indicate that this method can quickly utilize multi-temporal and multi-source remote sensing data to effectively identify surface deformations following natural disasters.

Intravenous Lipid Emulsion for the Treatment of Ivermectin Toxicity in a Cat: A Case Report

A two-years-old male cat weighing three kg was presented to the Referral Veterinary Polyclinic of ICAR – Indian Veterinary Research Institute (IVRI), Izatnagar with history of anorexia, no water intake, ataxia, head tilting downward, sudden recumbency and loss of vision. While taking history the owner declared about the use of off-label oral ivermectin preparation @ 2.5 mg/kg total dose (5 times the recommended dose) once only. Cat had high rectal temperature (105° F), normal mucus membrane, tachypnoea (70/min), tachycardia(145/min). At the beginning, the patient received 20% lipid emulsion (Intralipid) at 1.5 mL/kg body weight, Diazepam 0.5 mg/kg b. wt.

Permissioned blockchain network for proactive access control to electronic health records

BackgroundAs digital healthcare services handle increasingly more sensitive health data, robust access control methods are required. Especially in emergency conditions, where the patient’s health situation is in peril, different healthcare providers associated with critical cases may need to be granted permission to acquire access to Electronic Health Records (EHRs) of patients. The research objective of this work is to develop a proactive access control method that can grant emergency clinicians access to sensitive health data, guaranteeing the integrity and security of the data, and generating trust without the need for a trusted third party.MethodsA contextual and blockchain-based mechanism is proposed that allows access to sensitive EHRs by applying prognostic procedures where information based on context, is utilized to identify critical situations and grant access to medical data. Specifically, to enable proactivity, Long Short Term Memory (LSTM) Neural Networks (NNs) are applied that utilize patient’s recent health history to prognose the next two-hour health metrics values. Fuzzy logic is used to evaluate the severity of the patient’s health state. These techniques are incorporated in a private and permissioned Hyperledger-Fabric blockchain network, capable of securing patient’s sensitive information in the blockchain network.ResultsThe developed access control method provides secure access for emergency clinicians to sensitive information and simultaneously safeguards the patient’s well-being. Integrating this predictive mechanism within the blockchain network proved to be a robust tool to enhance the performance of the access control mechanism. Furthermore, the blockchain network of this work can record the history of who and when had access to a specific patient’s sensitive EHRs, guaranteeing the integrity and security of the data, as well as recording the latency of this mechanism, where three different access control cases are evaluated. This access control mechanism is to be enforced in a real-life scenario in hospitals.ConclusionsThe proposed mechanism informs proactively the emergency team of professional clinicians about patients’ critical situations by combining fuzzy and predictive machine learning techniques incorporated in the private and permissioned blockchain network, and it exploits the distributed data of the blockchain architecture, guaranteeing the integrity and security of the data, and thus, enhancing the users’ trust to the access control mechanism.

MODERN PARAMETERS OF LABORATORY EXPRESS DIAGNOSTICS IN INTENSIVE NEUROLOGY AND NEUROSURGICAL PRACTICE IN PATIENTS WITH CRANIOCEREBRAL INJURIES

The parameters listed in the article show the huge path that laboratory express diagnosis of emergency conditions in neurology has taken over the past 50 years. And this is not the limit - new unique technologies appear. The range of measured and calculated parameters continues to expand, which makes it possible to more fully and adequately assess the condition of a critically ill patient. Thus, a timely and qualitative study of the gaseous composition of blood is important for carrying out differential diagnosis, prescribing adequate treatment and monitoring the therapy effectiveness. The aim of the study was to highlight the current parameters of laboratory rapid diagnostics in intensive neurology and neurosurgical practice in patients with traumatic brain injury. There are two situations that necessitate the development of rapid methods for monitoring hemostasis in the neurological intensive care unit and neurosurgical operating room: the need to immediately determine the concentration or biological effect of anticoagulants. Some areas of surgical intervention are associated with increased blood loss due to coagulopathy, which requires timely replacement therapy. A long process of determining hemostatic parameters by routine methods in a general laboratory leads to a delay in diagnosis and, as a result, untimely treatment. Quite a few express methods designed to obtain specific information about the hemostasis process are currently available in the operating room. If these monitoring methods are used correctly, the research results are reliable, so some researchers use them to develop algorithms for determining the need for transfusion of blood components. However, the development of new monitoring methods requires close collaboration with scientists specialized in hemostasis, plus quality control must be established. It is necessary to prove the positive effect of rapid diagnostic methods on the result to ensure the possibility of their wide application in various operations.

Predictability of adult patient medical emergency condition from triage vital signs and comorbidities: a single-center, observational study

BackgroundVital signs and comorbid diseases are the first information evaluated in patients admitted to the emergency department (ED). In most EDs, triage of patients takes place with vital signs and admission complaints only. Comorbidities are generally underestimated when determining the patient’s status at the triage area. This study aims to assess the relationship between initial vital signs, comorbid diseases, and medical emergency conditions (MEC) in patients admitted to the ED.MethodsThis prospective study was designed as a single-center observational study, including patients admitted to a tertiary ED between 16.06.2022 and 09.09.2022. Patients younger than 18, readmitted to the ED within 24 h, or absence of vital signs due to cardiac arrest were excluded from the study. Vital signs and comorbid diseases of all patients were recorded. The mortality within 24 h, the need for intensive care unit admission, emergency surgery, and life-saving procedures were considered “medical emergency conditions”. The role of vital signs and comorbid diseases in predicting emergencies was analyzed by binary logistic regression.ResultsA total of 10,022 patients were included in the study; 5056 (50.4%) were female, and 4966 (49.6%) were male. Six hundred four patients presented with an MEC. All vital signs -except diastolic hypertension and tachycardia- and comorbidities were found statistically significant. Hypoxia (Odd’s Ratio [OR]: 1.73), diastolic hypotension (OR: 3.71), tachypnea (OR: 8.09), and tachycardia (OR: 1.61) were associated with MECs. Hemiplegia (OR: 5.7), leukemia (OR: 4.23), and moderate-severe liver disease (OR: 2.99) were the most associated comorbidities with MECs. In our study, an MEC was detected in 3.6% (186 patients) of the patients with no abnormal vital signs and without any comorbidities.ConclusionAmong the vital signs, hypoxia, diastolic hypotension, tachypnea, and tachycardia should be considered indicators of an MEC. Hemiplegia, leukemia, and moderate-severe liver disease are the most relevant comorbidities that may accompany the MECs.

Influence of lithodynamics of coastal area on the safety of railway operation on the Tuapse-Adler section of the North Caucasus Railway

The present paper considers the railroad bed on the Tuapse-Adler section of the North Caucasus Railway (Black Sea coast) in terms of its protection from wave scouring. Aim. To evaluate the influence of coastal lithodynamics on the safety of the railway operation on the section under consideration. The paper describes lithodynamic processes in the sea coastal zone and demonstrates the influence of coastal protection structures produced on lithodynamics in general and on adjacent sections, as exemplified by a specific section of the coast (1907–1910 km). The study involves a retrospective analysis of the step-by-step construction of trapping structures, and sea groins without full-fledged dumping of beach-forming material into the inter-groin compartments. The investigation and analysis of satellite images of 1907–1910 km coast within the Vodopadny-Lazarevskoye section indicate that lithodynamic processes remained unconsidered during the intensive construction of bank protection structures, which led to the beach erosion and the emergency condition of the seawalls along 1909–1910 km section. The paper provides recommendations for considering lithodynamic processes in the construction of railway protection structures, thereby increasing the safety of the railway operation.

Acute Approach to Central Nervous System Infections in Kazakhstan

Background Neuroinfections in children are a socially significant problem of our time, as they can lead to disability and death of the patient, which actualizes the need for their early clinical diagnosis. The purpose of the study: to identify patterns of clinical manifestations of central nervous system lesions in children with neuroinfections. Materials and methods The cases of neuroinfections in 101 children treated at the “City Clinical Infectious Diseases Hospital” (Shymkent) in the period from 2018 to 2022 were analyzed, of which 37 patients with viral neuroinfections, 64 with bacterial ones. Results The predominance of bacterial neuroinfections over viral ones was revealed, with a predominance among young boys. Headache or its equivalents (in children under one year old) were observed in 72.5%; most often in children with viral infections of the nervous system (81.2%), less often in patients with bacterial infections (65.4%), p 0.01. In most cases, the disease manifested with the phenomena of fever and vomiting. When assessing the neurological status, the duration of preservation of two frequently occurring meningeal signs (rigidity of the occipital muscles, Kernig’s symptom) was taken into account, which was 6 ± 1.3 days and 5 ± 1.1 days in the group with bacterial neuroinfections, and 4 ± 1.8 and 5 ± 1.7 days, respectively, in the group with viral neuroinfections (p 0.05). With pneumococcal etiology, the most severe and protracted cases of the course of neuroinfections are recorded. Frequent emergency conditions in infectious lesions of the central nervous system in the form of cerebral edema, septic shock, which occur more often in bacterial neuroinfections, have been identified. Conclusion Neuroinfections are characterized by a symptom complex of clinical manifestations, which should be interpreted by doctors in a timely and correct manner in order to diagnose early and minimize adverse outcomes of the disease.

Laparoscopic Versus Open Closure of Duodenal Perforations: A Retrospective Comparative Study in a Rural Hospital, Andhra Pradesh, India

Abstract Introduction: Evidence on the outcomes of laparoscopic surgeries, especially in emergency conditions such as peptic ulcer, remains unknown. A retrospective study was conducted in a rural surgical unit in Andhra Pradesh to compare morbidity, mortality, and duration of hospital admission in patients undergoing laparoscopic (Group L) and open (Group O) closure of duodenal perforations. Methods: Retrospective data of adult patients with peptic ulcer perforation treated by surgical approach during January 2012 and December 2017 were scrutinized. Pre- and postoperative records were abstracted for clinical conditions. Mortality was compared between the two groups with appropriate statistical tests. Results: A total of 120 patients, 60 in each group, were recruited for the study. The preoperative clinical characteristics of the two groups were similar. The mean duration of surgery was significantly higher in Group L (212.8 ± 29 min) compared to Group O (107 ± 16 min) (P < 0.001). Wound discharge (n = 3, 5%) and postoperative leak (n = 2, 3.3%) were the only complications noted in the L group. Several complications were noted in the O group including wound discharge (n = 51, 85%), wound dehiscence (n = 12, 20.0%), postoperative leak (n = 8, 13.3%), pneumonia (n = 1, 1.7%), and need for ventilation (n = 6, 10.0%). Three (5%) patients died in the hospital in Group O while none died in Group L. The average duration of hospital admission was 7.1 days (standard deviation [SD] =1.0 days) for Group L and 11.7 days (SD = 2.2 days) for Group O (mean difference: 4.6 days; 95% confidence interval: 4.6–5.2 days). Conclusion: Laparoscopic correction of duodenal ulcer perforation is both feasible and effective in reducing morbidity and mortality and overall treatment duration at peripheral centers.

Simplified Calculation Method for the Critical Load Bearing of Market-based Profile Emergency Steel Pier

A novel emergency steel pier, assembled from market-available profiles, has been developed to address the challenges associated with the "regular stockpiling and rapid emergency deployment" of bridge pier repair equipment. These challenges often involve significant labor and financial costs for manufacturing and maintenance. The buckling modes of the columns and pier-girder connections were considered. Using energy methods and plate-shell theory, an analytical formula for the critical load-bearing capacity of the steel pier under emergency conditions was derived. Numerical simulations were conducted for comparison and validation, resulting in an optimized and simplified method for calculating the critical load capacity, which is suitable for engineering applications.The study shows that the critical load-bearing capacity of the emergency steel pier exhibits distinct patterns under the influence of column buckling modes and pier-girder connection methods. In cases where the column is fixed at one end and hinged at the other, or fixed at both ends, the critical load for axisymmetric buckling is affected by factors such as elastic modulus, Poisson’s ratio, height, radius, wall thickness, and the number of buckling waves. When considering non-axisymmetric buckling, the number of circumferential buckling waves becomes an additional factor. A simplified method for calculating the critical load-bearing capacity was developed. The simplified formula depends only on a correction factor, modified buckling stress, the number of columns, and cross-sectional area. This makes it highly practical for emergency engineering applications.

Reinforcement of the steel columns structure of the industrial hall weakened by intense corrosion

Owing to the severe impact of the corrosive environment associated closely with the technological process, steel structures, including the columns described in the study, which constitute the main framework of the industrial hall, are prone to corrosion due to inadequate protection. This corrosion has resulted in emergency conditions. The paper presents proposals for strengthening these columns, preceded by expert assessments of their technical condition, geodetic measurements, load-bearing capacity analysis, and an evaluation of the technical feasibility of conducting repairs during continuous industrial operations. The results of these analyses are detailed in this paper

Prosthesis applications and challenges in children with earthquake-related amputations

BackgroundAmputations are among the most important traumatic injuries caused by earthquakes. However, data on amputee children and prosthesis application is quite limited in the literature. The aim of the study is to evaluate the injury-related data, stump problems, prosthesis application, difficulties and complications experienced with prosthesis during follow-up of children with 2023 Kahramanmaraş earthquake-related limb loss. Patients and methodsSociodemographic and injury-related data, pre-amputation and post-amputation interventions, prosthesis application, current prosthetic problems, and revision surgeries of the amputee children were recorded. ResultsMedian age of patients (n = 102) admitted to our center was 13.0 years. 67.6 % of patients had one or more concomitant injuries. Median time and number of amputations were 4 (0–57) days and 1 (1–4), respectively. Of the total 120 amputations, 67.5 % (n = 81) were lower extremity amputations. Most common amputation levels were transtibial (29.1 %, n = 35), transfemoral (22.5 %, n = 27), and transhumeral (15.8 %, n = 19). Most amputees (56.8 %) underwent revision surgery after initial amputation. Median duration of time from amputation to prosthesis application was 184 (28–314) days. For 25 prostheses, a socket revision was required. Six patients had surgical revision of the stumps to allow prosthetic fit and mobility (due to bone overgrowth, soft tissue failure, heterotopic ossification). ConclusionLimited healthcare facilities, surgeries performed under emergency conditions, accompanying multiple traumas, inadequate follow-up conditions, and additional difficulties arising from the pediatric patient group lead to difficulties in the care of pediatric amputee patients. Our results will guide the care of this vulnerable patient population in the event of a similar unfortunate disaster.

Enhancing Student Engagement: Technology Acceptance in Higher Education During Covid-19

COVID-19 has caused institutions across the sector to transition from conventional teaching and learning environments into virtual environments. Amidst this paradigm shift, academics have adopted a range of technology-based strategies to support the online learner. However, low attendance, engagement, and participation continue to challenge the execution of eLearning across the higher education (HE) sector. Within this narrative, there has been an interest in understanding the acceptance and adoption of technologies in education from the learners’ perspective. As a result, there has been an increased focus on technology acceptance models as a theoretical lens to unpack attitudes and beliefs relating to eLearning. Motivated by these environmental shifts, this study aims to capture themes and perspectives considered in educational literature worldwide to present future considerations for studied and practitioners as we emerge from the pandemic. By systematically reviewing global educational literature, the study aims to provide valuable insights and future considerations for both studied and practitioners as the HE sectors transitions out of the pandemic. The study is guided by the central study question: What influences the learners’ acceptance and continuation of use of education technologies during forced emergency conditions such as the COVID-19 pandemic? Based on these findings, we then share recommendations for education technology adoption in the HE sector.
