Intravascular migration of bullets and other foreign bodies is a rare but known complication of penetrating trauma. Missile embolization can represent a diagnostic challenge because it may present in various and unexpected ways. We present the case of a 54-year-old female who sustained shotgun pellet emboli to the pulmonary arteries following a left upper extremity gunshot wound and related vas...

OBJECTIVE To investigate and compare, using a retrospective clinical study, the clinical outcomes of penetrating craniocerebral gunshot wounds (PCGW) with respect to the trajectory of penetration in the axial plane. METHODS In total, 22 patients with PCGW caused by conflict, suicide attempt, or accidental firing were included in this study. They were divided into two groups: anteroposterior a...

Missile pulmonary emboli are rare sequelae of traumatic entry of projectile missiles-generally bullets or bullet fragments-in which access to the systemic venous circulation is established by the missile, making it possible for the missile to migrate to the pulmonary arteries. In the case introduced here, a 24-year-old male presented to the ER with a gunshot wound to the abdomen. In the early c...

Men with chronic, penetrating missile wounds of the brain were examined with two `spatial' tasks: a visually-guided stylus maze and a locomotor map-reading task. Men whose lesions involved the posterior part of the right cerebral hemisphere were significantly worse than those with left posterior lesions at stylus maze-learning. On the locomotor task, however, a highly significant deficit was fo...

To maximize the preservation of life and minimize the attendant morbidity of battle wounds, the surgeon attempts to localize or isolate the deleterious effects of injury and to optimize healing. This objective is best accomplished by removal of all foreign material and detached or severely disrupted muscle from the wound, by the establishment of open drainage of the wound’s recesses, and by mai...

The interception of a maneuvering antisurface missile, as in ballistic missile defense and ship defense scenarios, is formulated as an imperfect information, zero-sum, pursuit-evasion game with a state constraint imposed on the evader. Assuming that the perfect informationversion of the gamedoes not yield a successful result for the defense, the solution of this game is in mixed strategies. The...

Greyscales is a method for producing estimates of guided missile miss distance and missile warhead probability of kill. The associated computer code has been written to be portable and capable of being incorporated into a variety of simulations. The code has already been integrated into the Weapon Systems Division MECA and DUEL missile engagement simulations. It can also be integrated into larg...

Missile pose estimation in terminal guidance refers to the technique of estimating missile position and attitude by matching seeker images with pre stored reference images during the terminal phase of missile flight. This paper presents a method for estimating the position and orientation of the missile with respect to a known object using point correspondences between seeker and reference imag...

Aiming at the poor reliability of targets destroy for single base surface-to-air-missile weapon system, and the existing shortcomings of anti-destroying ability for missile networking system, this paper research on system level surface-to-air-missile defense system network features. On the analysis of the missile launching area boundary, the kill probability, the operational time and threat lev...

In order to survive as a carnivorous species it was imperative that Homo sapiens hunted efficiently. It is speculative, but distinctly possible, that not only the implements of hunting but also the psychological traits of the chase led to, or at least accentuated, the proclivity of our ancestors to kill and maim their fellows. Our modern fragile and turbulent societies must surely mirror the vi...
