The energy density wake produced by a heavy quark moving through a strongly coupled N = 4 supersymmetric Yang-Mills plasma is computed using gauge/string duality.Introduction.-The discovery that the quark-gluon plasma produced in heavy ion collisions at RHIC behaves as a nearly ideal fluid [1,2] has prompted much interest in understanding the dynamics of strongly coupled non-Abelian plasmas. Gauge/string duality [3,4] allows one to compute many observables probing nonequilibrium dynamics of thermal N = 4 supersymmetric Yang-Mills (SYM) theory, including the rate of energy loss of a heavy quark moving through an SYM plasma [5]. (See also Refs. [6,7,8,9, 10] and references therein.) Energy transferred to the plasma from the moving quark will cause the energy density of the plasma, in the vicinity of the quark, to deviate from its equilibrium value. That is, the moving quark will create an energy density "wake" which moves with it through the plasma. The structure of this wake is of interest for studies of jet quenching and jet correlations in heavy ion collisions [11,12]. We evaluate this energy density perturbation, ∆T 00 (x) , and display the resulting energy density wake in the case of subsonic, transsonic, and supersonic motion [20].

“…In contrast, buccal mucosa is usually the most affected site in the solitary cases (4,6). Solitary or multifocal, they are thought to have a reactive nature and usually they regress spontaneously or after incomplete removal, such as an incisional biopsy (3,5,6). Clinically, OMA presents as a black or brownish lesion with a flattened surface (5,6).…”

“…It may present as a solitary or multifocal lesion; however, these two variants exhibit different demographic features (5). According to Yaron et al, only about 53 patients with 72 cases of oral MA have been reported in the literature (43 solitary and 10 multifocal) (5). Although a female predominance has been observed in both variants, multifocal OMA presents an equal gender distribution and tends to occur more frequently on the palate (5).…”

“…Oral lesions occur almost exclusively in black females, affecting a wide age range (from the first to the eighth decades) (5) OMA is a distinct entity not related to the cutaneous MA, which is considered to be a variant of seborrheic keratosis (5). It may present as a solitary or multifocal lesion; however, these two variants exhibit different demographic features (5).…”
