• Sommario/riassunto: This brief analyzes the characteristics of a microring resonator (MRR) to perform communication using ultra-short soliton pulses. The raising of nonlinear refractive indices, coupling coefficients and radius of the single microring resonator leads to decrease in input power and round trips wherein the bifurcation occurs. As a result, bifurcation or chaos behaviors are seen at lower input power of 44 W, where the nonlinear refractive index is n2=3.2×10−20 m2/W. Using a decimal convertor system, these ultra-short signals can be converted into quantum ; information. Results show that multi solitons with FWHM and FSR of 10 pm and 600 pm can be generated respectively. The multi optical soliton with FWHM and FSR of 325 pm and 880 nm can be incorporated with a time division multiple access (TDMA) system wherein the transportation of quantum information is performed.

• Sommario/riassunto: In Our Children, Their Children, a prominent team of researchers argues that a second-rate and increasingly punitive juvenile justice system is allowed to persist because most people believe it is designed for children in other ethnic and socioeconomic groups. While public opinion, laws, and social policies that convey distinctions between "our children" and "their children" may seem to conflict with the American ideal of blind justice, they are hardly at odds with patterns of group differentiation and inequality that have characterized much of American history. Our Children, Their Children provides a state-of-the-science examination of racial and ethnic disparities in the American juvenile justice system. Here, contributors document the precise magnitude of these disparities, seek to determine their causes, and propose potential solutions. In addition to race and ethnicity, contributors also look at the effects on juvenile justice of suburban sprawl, the impact of family and neighborhood, bias in postarrest decisions, and mental health issues. Assessing the implications of these differences for public policy initiatives and legal reforms, this volume is the first critical summary of what is known and unknown in this important area of social research.
