This paper describes the development of a software tool for optimizing large-scale air combat tactics using stochastic genetic algorithms. The tool integrates four key components: 1) autonomous blue/red player agents, with their individual aircraft and tactics; 2) an engagement simulator used to play out a tactical scenario; 3) performance metrics reflecting engagement outcome and tactical adva...

Architectural tactics are design decisions intended to improve some system quality factor. Since their initial formulation, they have been formalized, compared with patterns and associated to styles. However, the initial set of tactics for security has only been refined once. We have examined the tactics set and classification from the viewpoint of security research, and concluded that some tac...

Associations between vocally expressed emotional arousal, influence tactics, and demand/withdraw behavior were examined in a treatment-seeking sample of 130 seriously and stably distressed, married, heterosexual couples and in a community sample (N = 38) of 18 married heterosexual and 20 dating heterosexual couples. Fundamental frequency was used to measure emotional arousal, and computational ...

Substantial changes in cardiac energy metabolism have been observed in a variety of heart diseases. Understanding the functional role of these changes is critical for developing the concept of metabolic intervention for heart disease. The use of genetically engineered mice in recent studies has made it possible to alter cardiac metabolism independently of secondary influence by disease and, thu...

The need to vary body temperature to optimize physiological processes can lead to thermoregulatory behaviours, particularly in ectotherms. Despite some evidence of within-population phenotypic variation in thermal behaviour, the occurrence of alternative tactics of this behaviour is rarely explicitly considered when studying natural populations. The main objective of this study was to determine...

Males that follow alternative reproductive tactics might differ in their investment into testis development and sperm production. The resource-allocation hypothesis predicts that males following a sneaker tactic should invest more into sperm production than dominant territorial males which should invest more into mate guarding. This hypothesis is supported by studies in species where individual...

Adult male Megacyllene robiniae (Förster) (Coleoptera: Cerambycidae) that are paired with a female often are challenged by conspecific males that attempt to displace them. In staged laboratory bouts, challenging males used seven distinct tactics to displace defending males, including wedging their head between the defender and the female (termed wedging), straddling the mated pair and pulling t...

The treatment tactics for subclavian artery occlusion include the more commonly used endovascular therapy rather than surgical intervention. We present a case of a 61-year-old woman with dialysis-dependent chronic renal failure who experienced left finger necrosis in the left upper extremity. To salvage the limb, we performed femoro-axillary (fem-ax) artery bypass using an autologous saphenous ...
