T 3 entirely covered with band; those spots and bands formed of yellowish setae. T 4 and T 5 clothed with mixed long erect yellowish and black setae. T 6 with black setal delimiting pygidial area. Head. Remarkably enlarged; in dorsal view, subquadrate, significantly wider than mesosoma and approximately 0.8× as wide as T 2, strongly convex and prolonged behind eyes, with posterolateral angles broadly rounded and occipital margin nearly straight. Vertex and frons coarsely reticulo-punctate. Eyes small, ovoid, widely separated from mandibular articulation (malar space about 0.8 LED). Scrobal carina well-developed. Antennal tubercles large, rounded, carinate above. Clypeus with deeply concave median area delimited above by elevated bituberculate portion, clypeal anterior margin straight, laterally distinctly tuberculate. Mandible robust, blunt apically, with subbasal blunt tooth inside. F 1 cylindrical throughout, 1.5× longer than its maximal width, as long as F 2 and F 3 combined. Mesosoma. Quadrangular, slightly longer than its maximal width, nearly parallel sided behind pronotum, dorsally reticulate-punctate. Pronotum slightly widened, anteriorly slightly arcuate, with humeral angles acute. Scutellar scale very small but visible. Propodeal posterior face abruptly declivitous, coarsely punctate. Meso- and metapleuron polished and shiny. Mid and hind tibiae with double row of strong spines. Metasoma. Ovoid, sessile. T 1 notably wider than long (transverse). T 2 longitudinally wrinkled on anterior third, largely to finely reticulo-punctate posteriorly. Pygidial area strongly widened anteriorly, pointed posteriorly, longitudinally irregularly wrinkled on basal two thirds, finely sculptured apically and bordered laterally with distinct carina. S 1 with large blunt tooth. MALE. Unknown. Distribution. Egypt (South Sinai). Etymology. The specific name is dedicated to Arkady S. Lelej, authority on Mutillidae and Aculeate classification and evolution.Published as part of El-Torkey, Ashraf M., Oshaibah, Alaa Din A., Salem, Magdi M.

An essential approach to the age assessment in undocumented minors in conflict with the law
No full textIn forensic contexts, assigning an age to a living child of unknown identity may be necessary when the child is suspect in a crime, when penal codes differentiate law and punishment for children of different ages or if the child is a refugee.
The age of criminal responsibility in the UK is the lowest in Europe with other European Union Member States setting the age of criminal responsibility between 14 and 16 years. In the absence of a known birth date, any assessment of age will be difficult.
The age assessment should include a comprehensive physical description of the person including: physical development, bone maturity which is observed on radiographs as the development and fusion of the long bone growth centres (e.g. in the hand and wrists) and dental age estimation (including grading tooth development both clinically and on dental radiographs).
Currently there is no medical test or a group of tests that will absolutely and accurately let us know the exact chronological age of a human being. There will always be an uncertainty related to the estimate, and correctly expressing this uncertainty is just as important as the actual estimate.
More research is needed to define more precisely the best standard approach for age estimation based on a combination of different methods. Furthermore, professionals working with children should always strive to take ethical guidelines into consideration in making decisions of such minors

A review of the medical diagnostic techniques for forensic age estimation (FAE) in minors (2nd part)
No full textMultifactorial techniques have been proposed to increase accuracy and help control for variation that may occur in any one single age indicator’. The different methods are associated with varying degrees of uncertainty and precision. No age estimation method or group of methods today can determine the exact chronological age of a minor. Much research is still needed on age estimation methods. This is still an ongoing process with advance imaging technology and statistical interpretation
A review of the medical diagnostic techniques for forensic age estimation (FAE) in minors (1st part)
No full textAge estimation presents a complex problem and requires considerable experience in recognizing significant changes and allowing for their variability within any particular population. No age estimation method or group of methods today can determine the exact chronological age of a child. The different methods are associated with varying degrees of uncertainty and precision. Because the assessment of whether a person is an adult or not, is a constant challenge for forensic science, the aim of present paper is to describe the medical testing techniques used for age assessment in minors with the purpose of determining the most accurate technique for age estimation
IoD swarms collision avoidance via improved particle swarm optimization
No full textDrones flights have been investigated widely. In the presence of high density and complex missions, collision avoidance among swarm of drones and with environment obstacles becomes a challenging task and indispensable. This paper aims to enhance the optimality and rapidity of three dimensional IoD path generation by improving the particle swarm optimization (PSO) algorithm. The improvements include using chaos map logic to initialize the population of PSO. Also, adaptive mutation is utilized to balance local and global search. Then, the inactive particles are replaced by new fresh particles to push the solution toward global optimal. Furthermore, Monte Carlo simulation is carried out and the results are compared with slandered PSO and with recent work CIPSO. The results exhibit significant improvement in convergence speed as well as optimal solution which prove the ability of proposed method to generate safety path for IoD formation without collision with terrain obstacle and among drones.The authors would like to acknowledge the support of the department of the computer engineering at King Fahd University of Petroleum and Minerals for this work.Ahmed, G (corresponding author), King Fahd Univ Petr & Minerals, Comp Engn Dept, Dhahran, Saudi Arabia.
