TL;DR: An efficient quantum algorithm for simulating the evolution of a quantum state for a sparse Hamiltonian H over a given time t is presented in terms of a procedure for computing the matrix entries of H.
Abstract: We present an efficient quantum algorithm for simulating the evolution of a quantum state for a sparse Hamiltonian H over a given time t in terms of a procedure for computing the matrix entries of H. In particular, when H acts on n qubits, has at most a constant number of nonzero entries in each row/column, and ||H|| is bounded by a constant, we may select any positive integer k such that the simulation requires O((log*n)t1+1/2k) accesses to matrix entries of H. We also show that the temporal scaling cannot be significantly improved beyond this, because sublinear time scaling is not possible.

TL;DR: The relationship of voluntary work, school climates, and family values to public interest as a life goal of adolescents is presented for a sample of 5,579 12-18 year olds in three stable and four transitional democracies as mentioned in this paper.
Abstract: The relationship of voluntary work, school climates, and family values to public interest as a life goal of adolescents is presented for a sample of 5,579 12–18 year olds in three stable and four transitional democracies. In five of the seven countries, females were more likely than males to be engaged in voluntary work, and in all seven countries girls were more likely than boys to report that their families encouraged an ethic of social responsibility. Regardless of gender or country, adolescents were more likely to consider public interest an important life goal when their families emphasized an ethic of social responsibility. In addition, engagement in volunteer work and a sense of student solidarity at school were formative components of public interest as a life goal for youth in some but not all countries.

TL;DR: Island populations are more prone to extinction than mainland populations, with island endemic species having higher extinction rates than nonendemic species and inbreeding depression is one possible explanation for this.
Abstract: Island populations are more prone to extinction than mainland populations, with island endemic species having higher extinction rates than nonendemic species. Inbreeding depression is one possible expla- nation for this. Insular populations are expected to suffer increased inbreeding relative to mainland popula- tions due to bottlenecks at foundation and to lower subsequent population sizes. Inbreeding coefficients for 182 nonendemic and 28 endemic island populations were estimated from allozyme and microsatellite het- erozygosities in island and related mainland populations. Island populations were significantly inbred, with inbreeding coefficients significantly higher in endemic than nonendemic island populations. Many island populations showed levels of inbreeding associated with elevated extinction rates in domestic and laboratory species. Inbreeding depression cannot be excluded as a factor in the extinction proneness of island popula- tions.

TL;DR: This review puts the current knowledge of marine picocyanobacterial genomics into an environmental context and presents previously unpublished genomic information arising from extensive genomic comparisons in order to provide insights into the adaptations of these marine microbes to their environment and how they are reflected at the genomic level.
Abstract: Marine picocyanobacteria of the genera Prochlorococcus and Synechococcus numerically dominate the picophytoplankton of the world ocean, making a key contribution to global primary production. Prochlorococcus was isolated around 20 years ago and is probably the most abundant photosynthetic organism on Earth. The genus comprises specific ecotypes which are phylogenetically distinct and differ markedly in their photophysiology, allowing growth over a broad range of light and nutrient conditions within the 45 degrees N to 40 degrees S latitudinal belt that they occupy. Synechococcus and Prochlorococcus are closely related, together forming a discrete picophytoplankton clade, but are distinguishable by their possession of dissimilar light-harvesting apparatuses and differences in cell size and elemental composition. Synechococcus strains have a ubiquitous oceanic distribution compared to that of Prochlorococcus strains and are characterized by phylogenetically discrete lineages with a wide range of pigmentation. In this review, we put our current knowledge of marine picocyanobacterial genomics into an environmental context and present previously unpublished genomic information arising from extensive genomic comparisons in order to provide insights into the adaptations of these marine microbes to their environment and how they are reflected at the genomic level.
