Optimizing the Steering of Driverless Personal Mobility Pods with a Novel Differential Harris Hawks Optimization Algorithm (DHHO) and Encoder Modeling.

This paper aims to improve the steering performance of the Ackermann personal mobility scooter based on a new meta-heuristic optimization algorithm named Differential Harris Hawks Optimization (DHHO) and the modeling of the steering encoder. The steering response in the Ackermann mechanism is crucial for automated driving systems (ADS), especially in localization and path-planning phases. Various methods presented in the literature are used to control the steering, and meta-heuristic optimization algorithms have achieved prominent results.

Clinical and Radiographic Predictors of Successful Coronary Angiography Through Right Radial Artery Access.

: One of the limitations of the right radial access approach is complex vessel anatomy, such as subclavian tortuosity. Several clinical predictors have been proposed for tortuosities, such as older age, female sex and hypertension. In this study, we hypothesised that chest radiography would add predictive value to the traditional predictors.

Evaluation of 3D Vulnerable Objects' Detection Using a Multi-Sensors System for Autonomous Vehicles.

One of the primary tasks undertaken by autonomous vehicles (AVs) is object detection, which comes ahead of object tracking, trajectory estimation, and collision avoidance. Vulnerable road objects (e.g.

Global longitudinal strain detects subtle left ventricular systolic dysfunction in Duchenne muscular dystrophy patients and carriers.

Background: With the continuous improvement of the respiratory care of Duchenne muscular dystrophy patients, cardiac manifestations (heart failure and arrhythmias) become the leading causes of morbidity and mortality. Early identification of cardiac muscle affection is crucial to start anti-failure drugs that reverse remodeling and improve prognosis. This study aimed to detect subtle cardiac changes in Duchenne muscular dystrophy patients and carriers using electrocardiography and echocardiography.

Accidental Pyrethroid Ingestion in Toddler: Near-Fatal Atypical Presentation and Successful Recovery.

We are reporting a case of pyrethroid poisoning with atypical presentation in a 21-month-old toddler who was transferred to us from a peripheral center. Signs and symptoms at presentation were predominantly of cardiopulmonary dysfunction contrary to more common presenting features of gastrointestinal and neurological impairment. The reason for this seems to be the aspiration pneumonitis as a consequence of vomiting induced by parents at home, rather than the toxin itself even though a rather rapid progression of lung injury does not rule out the possibility.

A Multi Center Experience: Is Valve Replacement Safe for Patients with Hugely Dilated Left Ventricle?

Background: Dilated left ventricle occurs in chronic aortic and mitral regurgitations. We describe the early outcome of mitral and aortic valve replacement for patients with severely dilated left ventricle in different surgical interventions.

Methods: From March 2014 to December 2018, 620 patients with left ventricular end-diastolic diameter (LVEDD) of ≥ 70 mm underwent valve replacement procedures in 8 cardiac surgery centers in Egypt.

Red blood cell distribution width and coronary artery disease severity in diabetic patients.

The purpose of the study is to evaluate the relationship between red blood cell distribution width (RDW) and coronary calcium score in diabetic patients. Hematological parameters of 100 diabetic (Type II) patients were assessed. Computed tomographic angiography was used to asses coronary artery calcium (CAC) score.

Right Ventricular Outflow Tract Systolic Excursion and Fractional Shortening: Can These Echocardiographic Parameters be Used for the Assessment of Right Ventricular Function?

Background: Echocardiographic right ventricular (RV) function assessment is difficult and still a gray area despite rapid advancement of imaging modalities. The aim of this study is to assess the role of echocardiographic RV outflow tract (RVOT) function in the form of RVOT fractional shortening (RVOT FS) and RVOT systolic excursion (RVOT SE) for the assessment of RV function.

Methods: We studied ninety individuals divided equally into two groups.

Pre-ejection mitral annular motion velocity responses to dobutamine infusion: A quantitative approach for assessment of myocardial viability.

Background: Dobutamine stress echocardiography (DSE) is widely used for detection of myocardial viability. The main limitation of DSE is its subjective interpretation. Assessment of mitral annular motion velocities with tissue Doppler imaging is a simple and quantitative measurement.

Assessment of cardiac involvement of hepatitis C virus; tissue Doppler imaging and NTproBNP study.

Introduction: Hepatitis C disease burden is substantially increasing in Egyptian community, it is estimated that prevalence of Hepatitis C virus (HCV) in Egyptian community reach 22% of total population. Recently there is a global alert of HCV cardiovascular complications.

Objective: To evaluate LV diastolic functions of HCV patients using tissue Doppler Imaging and NTPBNP.
