T elimination of health disparities in the United States is a national priority and overriding goal for Healthy People 2010 (HP 2010). Surveillance of health indicators among minority populations is essential to eliminating disparities. Surveillance is critical for program planning, policy making, evaluating population-based strategies, and tracking progress toward national and state objectives.

One new species of Riethia Kieffer, Riethia manauara n. sp., is described and figured as male, pupa and larva. The generic diagnosis for pupae and larvae are emended. The specimens were collected from water systems in the Amazon Rainforest in northern Brazil.

Abstract. The operational advantages of electrodynamic tethers of moderate length are becoming evident from studies of collision avoidance. Although long tethers (of order of 10 kilometers) provide high efficiency and good adaptability to varying plasma conditions, boosting tethers of moderate length (~ 1 kilometer) and suitable design might still operate at acceptable efficiencies and adequate...

Two new species of Stenochironomus Kieffer, 1919 are described in Brazil. New records of Stenochironomus nudipupa Borkent, 1984 and S. gladius Borkent, 1984 from Brazil, new data on geographical distribution of S. jubatus Borkent, 1984 and S. triannulatus Borkent, 1984 from the State of Roraima, and S. bacrionis Borkent, 1984 recorded from the State of Amazonas, as well as emended descriptions ...

Drosophila, Wnt, FGF, Jak/Stat, Rho, Rac, RhoGEF, Pebble, Naked Cuticle The site for the latest installment of the Fly Meeting (March 7–11) was downtown Philadelphia. The conference offered an illustration of all that is great about the Drosophila field bringing together evolutionary biologists, immunologists and everyone in between. Here I will provide a small sample of several advances from t...

We show that the oscillatory driving of crystal surfaces can induce pattern formation or smoothening. Depending on driving conditions, step bunching and meandering, mound formation, or surface smoothening may be seen in the presence of a kinetic asymmetry at the steps or kinks. We employ a step model to calculate the induced mass flux along misoriented surfaces, which accounts for surface dynam...

We study the control of modulational instability and pattern formation in a nonlinear dissipative feedback system with a periodic modulation of the material refractive index. We use a one-dimensional photonic lattice in a single-mirror feedback configuration and identify three mechanisms for pattern control: bandgap suppression of instability modes, periodicity induced pattern modes, and orient...

We present some numerical results obtained from a simple individual-based model that describes clustering of organisms caused by competition. Our aim is to show that, even when a deterministic description developed for continuum models predicts no pattern formation, an individual-based model displays well-defined patterns, as a consequence of fluctuation effects caused by the discrete nature of...

We studied the effect of nearest pattern interaction on a global pattern formation in a two-dimensional space, where patterns are to grow initially from a noise in the presence of a periodic supply of energy. Although our approach is general, we found that this study is relevant in particular to the pattern formation on a periodically vibrated granular layer, as it gives a unified perspective o...
